Description

Technical Field

[0001] The utility model relates to the field of bag-making machines, in particular to a material feeding device for a bag-making machine. Background Technique

[0002] A bag-making machine is a machine for making various plastic packaging bags or packaging bags of other materials. Its processing range is packaging bags of various sizes, thicknesses, and specifications made of plastic or other materials. Generally speaking, plastic packaging bags are the main products.

[0003] In the prior art, a material feeding device for a film bag-making machine proposed in the utility model patent with the publication number of CN 219525761 U detects the tension of the film fed from the feeding cylinder through a tension roller. If the tension is too large, it controls the tension roller to move upward. If the tension is too small, it controls the tension roller to move downward, thereby achieving the purpose of stabilizing the tension of the film during the feeding process.

[0004] However, the device only has a set of feeding rollers. During actual use, after the raw materials on the feeding roller are used up, the staff needs to stop the machine to disassemble and replace the feeding roller, which will affect the bag-making efficiency and progress. If the feeding roller is not replaced in time, more time will be wasted. At the same time, it does not have the ability to limit and correct the deviation of the raw materials. If the raw materials deviate on the guide roller, it will cause the raw materials to fold or break away, thereby affecting the processing quality. Therefore, we need to upgrade and transform on the basis of the existing technology to overcome the problems and deficiencies it has. Content of the Utility Model

[0005] The purpose of the utility model is to provide a material feeding device for a bag-making machine to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] Design a material feeding device for a bag-making machine, including a device body.

Two groups of limiting frames are screwed oppositely on the bidirectional screw. A guiding hole is provided at the lower end of the limiting frame, and a guiding rod is provided at the lower end of the bidirectional screw and the guiding rod penetrates through the guiding hole.

[0010] Further, the installation grooves are formed on the rear bracket and there are two groups. The feeding roller and the discharging roller are respectively rotatably installed in the two installation grooves. The positioning pin is arranged in a T-shaped structure.

[0011] Further, the bidirectional screw and the guiding rod are rotatably installed inside the front bracket and are located below the lower guiding roller. The external knob rotates on the outside of the front bracket.

Detailed implementation manners

[0023] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0024] As Figure 1 -4 shows, the design of a bag-making machine's feeding device provided in this embodiment includes a device body 1. The device body 1 contains a rear bracket 2, a disassembly and assembly component 5, a front bracket 6 and a limiting component 9. Inside the rear bracket 2, a feeding roller 3 and a discharging roller 4 are respectively installed from top to bottom. The disassembly and assembly component 5 is installed outside the feeding roller 3 and the discharging roller 4 and is fixed to the rear bracket 2. The front bracket 6 is arranged at the front end of the rear bracket 2. Inside the front bracket 6, two groups of lower guide rollers 7 and a group of upper guide rollers 8 are respectively arranged. The limiting component 9 is arranged at the lower end of the lower guide roller 7.

[0025] Preferably, the disassembly and assembly component 5 includes an installation groove 51. A limiting block 52 is inserted into the installation groove 51. The limiting block 52 and the outside of the installation groove 51 are correspondingly provided with a mounting plate 53. A positioning hole 54 is opened on the mounting plate 53 and a positioning pin 55 is penetrated through the positioning hole 54. The installation groove 51 is opened on the rear bracket 2 and there are two groups. The feeding roller 3 and the discharging roller 4 are respectively rotatably installed inside the two groups of installation grooves 51. The positioning pin 55 is set as a T-shaped structure;

[0026] Through the cooperation of the installation groove 51 and the limiting block 52, it is convenient to install the feeding roller 3 and the discharging roller 4 in the rear bracket 2. Through the cooperation of the positioning hole 54 and the positioning pin 55, it is convenient to fix the limiting block 52, thereby realizing the fixed limit of the material roller, facilitating the quick disassembly and assembly of the two groups of material rollers, facilitating the switching of the material roller for work, and eliminating the need to stop the machine for disassembling and assembling the material roller.

[0027] Preferably, the limiting component 9 includes a bidirectional screw 91. External knobs 92 are provided at both ends of the bidirectional screw 91. Two groups of limiting frames 93 are screwed oppositely on the bidirectional screw 91. A guiding hole 95 is provided at the lower end of the limiting frame 93. A guiding rod 94 is provided at the lower end of the bidirectional screw 91 and the guiding rod 94 penetrates through the guiding hole 95. The bidirectional screw 91 and the guiding rod 94 are rotatably installed inside the front bracket 6 and are located at the lower end of the lower guide roller 7. The external knob 92 rotates on the outside of the front bracket 6. An arc-shaped groove structure is provided at the upper end of the limiting frame 93. The upper end of the limiting frame 93 is slidably attached to the lower end of the lower guide roller 7.

[0028] By means of the external knob 92, it is convenient to control the rotation of the bidirectional screw 91. Through the cooperation of the bidirectional screw 91 and the guiding rod 94, it is convenient to control the opposite movement of the two groups of limiting frames 93. The two groups of limiting frames 93 can limit and correct the intermediate bag-making raw materials, avoiding problems such as wrinkles and offsets during the raw material transmission process, and improving the processing quality and stability of the device.

[0029] The working principle and working process of the present utility model: During use, first install the feeding roller 3 and the discharging roller 4 in the rear bracket 2, pass the raw materials through the lower guide roller 7 and the upper guide roller 8 respectively and connect them to the bag-making machine. By means of the external knob 92, the rotation of the bidirectional screw 91 can be controlled. Through the bidirectional screw 91, the limiting frame 93 can be driven to move vertically along the guiding rod 94. The two groups of limiting frames 93 move towards each other and fit on both sides of the raw material, and the limiting and correcting operation of the intermediate bag-making raw materials can be realized, facilitating the maintenance of its conveying stability, avoiding problems such as wrinkles and offsets during the raw material transmission process, and improving the processing quality and stability of the device. After the raw materials on the feeding roller 3 are emptied, the raw materials on the discharging roller 4 can be connected to each guide roller according to the route for continuous processing. Subsequently, the positioning pin 55 on one side of the feeding roller 3 is pulled out from the positioning hole 54, and then the limiting block 52 is disassembled and the feeding roller 3 is replaced, without affecting the discharging of the discharging roller 4. The working efficiency of the device is effectively improved, and there is no need to stop the machine for loading and unloading, and the operation is simple and convenient.
