Valve bags are very popular in the domestic market, especially in the small commodity wholesale market and the food industry. Many people who make it do not know that this kind of bag is made by a special valve bag making machine. What is the working process of the valve pocket bag making machine, let’s learn more about it together!

The working flow of valve bag making machine

1. Hopper feeding

The bag making machine is a hopper on which the powder is transported to the packaging machine by the feeder throughout the day. Device Control. The sealing paper roll is driven by the guide roll to the lapel forming machine. After bending, it is lapped into a cylinder with a longitudinal sealer. The material of the bag making machine is automatically measured and then loaded into the bag. The transverse sealer intermittently pulls down the bag cylinder while cutting off the heat seal to form a flat bag with overlapping longitudinal seams on three sides, and seals the seal of the bag.

2. Cutting

How to carry out the cutting of the bag making machine, the metal cutting process of the bag making machine is actually very similar to the metal extrusion process. When the gravure printing machine cuts plastic materials, the material begins to elastically deform under the action of the tool. As the tool continues to cut in, the stress and strain inside the metal continue to increase. When the stress reaches the yield point of the material, plastic deformation begins; Using computer control, the advanced (servo) fixed-length system makes the sealing and cutting size error small, and the electric eye is installed to make the printed pattern position. The length of the bag can be adjusted by computer numerical control. If there is a problem with the printing bag, the machine will automatically stop and give a warning sound.

As a commonly used screening equipment in the mining industry, the vibrating screen is in a long-term working state and the operation is also a fine operation, so there will be more or less problems. If the feeding is too slow, it will affect the screening efficiency of the vibrating screen. The reasons for the slow feeding of the vibrating screen and the adjustment methods have been introduced in detail below. Let’s take a look.

The reason why the vibrating screen feeds slowly

1. Vibration motor problem

(1) The motor power cannot reach or the motor power is normal but the speed is slow, and the 1500 rpm that cannot be used will also cause the feeding to be slow.

(2) The steering problem of the vibration motor: the steering of the motor is divided into two types: forward rotation and reverse rotation. Under normal circumstances, the steering of the two motors is in the opposite direction, but if the user connects the positive and negative poles incorrectly when the power is connected, it will cause When the motor rotates in the same direction, there will be a problem of slow or no material feeding on the screen surface.

(3) The problem of the installation position of the motor: There are three installation positions of the vibrating motor of the linear screen, which are the bottom, the two sides, and the upper part. If the vibration motor is installed close to the feeding port, the screen surface material will run for a certain distance and then the speed will decrease and stay on the screen surface.

2. The amount of screen cloth is too large

The excessive amount of cloth on the screen surface is also the reason for the slow feeding of the vibrating screen. When the screen is added, the load of the motor is also added accordingly, and there will be a problem of slow feeding.

As an important part of the tractor, the clutch must be reasonably matched to fully satisfy the use of the tractor clutch. It needs to be lubricated in the process of use. Then in the process of selecting lubricating oil, what should we do? to operate it?

We want to make high-quality lubricating greases from base oils, thickeners and additives. The performance of different types of greases with different grades of the same type is very different, and the allowable rotation limits are also different. Therefore, the tractor clutch must be clear when choosing!

1. The choice of diesel

Diesel is divided into light and heavy diesel, and agricultural tractors generally use light diesel. Light diesel oil is generally divided into No. 10, No. 0, -10, -20, -35 and other grades according to its freezing point. In order to save money, in many areas, apart from those who are engaged in transportation in the cold winter, they need to prepare -35 oil. Generally, they only need to prepare two kinds of diesel oil, 0 and -20, for agricultural production. Use No. 0 diesel in summer and No. 11 in winter. In other areas, the appropriate number of diesel can be selected according to the specific local temperature.

2. The choice of oil

Diesel engine oil is required for agricultural diesel engines. Diesel engine oil is divided into three types: No. 8, No. 11 and No. 14. Generally, use No. 8 oil in summer and No. 11 oil in winter.

3. Selection of gear oil

Gear oil is divided into 20th and 309th. 30 in summer; 20 in winter. Here to remind the owners of the machine, it is strictly forbidden to use engine oil instead of gear oil, or to mix diesel and kerosene in the gear oil, so as not to reduce its viscosity, weaken the lubricating performance, and accelerate gear wear.

We are all concerned about the output of the ball briquetting machine. If the output of the ball briquetting machine does not meet the requirements, then even saving energy is useless. Next, we will focus on how to increase the pressure of the ball briquetting machine and supporting facilities without changing. The output of the ball machine?

How to increase the output of the ball press

1. The composition of the pressed material, that is, the degree of adhesion is very important and is a key factor in determining the ball-forming effect and productivity. Therefore, before the ball is pressed, the material should be fully dry-mixed to ensure smooth production.

2. The material of the pressure roller is very important. The selected alloy steel material is too single, and long-term use will cause wear and tear, which will have a great impact on production efficiency.

3. The motor and deceleration device of the briquetting machine are also very critical, and a good motor and deceleration device can also indirectly increase the output.

Precautions for the operation of the ball press

1. During the production process of the briquetting machine, metal and stones should not be allowed to enter the inside of the machine, so as to avoid construction hazards and damage to the structure of the machine;

2. The particle size of the materials used in the briquetting machine must be kept within 3 mm, otherwise it will affect the production efficiency and quality, and also reduce the service life of the briquetting machine;

3. Before starting, it must be ensured that the inside of the machine is empty, and no material is allowed to start;

4. It is strictly forbidden for non-professionals to disassemble and modify the fuselage;

5. It is necessary to regularly maintain and maintain the ball press, and it is strictly forbidden to use it with faults to avoid unnecessary dangers and losses.
