Description

Technical Field

[0001] This utility model relates to the technical field of woven bag production equipment, and in particular to a positioning and cutting device for woven bag production. Background Technology

[0002] Woven bags are one of the most widely used packaging materials in daily life. Their raw materials are generally various chemical plastics such as polyethylene and polypropylene. In the production process of woven bags, a positioning and cutting device is needed to cut the woven bags.

[0003] A positioning and cutting device for woven bag production, with application number CN202222723732.6, includes a frame and a first reduction motor fixedly installed on one side of the frame. Two conveyor rollers are rotatably mounted on the frame, one of which is fixedly connected to the output end of the first reduction motor. Several first pulleys are fixedly mounted on several conveyor rollers, and a belt is provided between the several first pulleys and connected by the belt. A U-shaped frame is fixedly mounted on the upper surface of the frame, and a flattening component is provided on the U-shaped frame. Two connecting plates are fixedly mounted on the lower surface of the frame. This allows the front cutter and the rear cutter to move closer to each other to perform double-sided cutting of the woven bag between the front cutter and the rear cutter. This solves the problem that when cutting on one side of the woven bag, local depressions occur on the cut side due to the force on one side, resulting in uneven cut surfaces and insufficient cutting. The device is simple to operate and convenient to use. However, the front and rear cutters work together to cut. If the front and rear cutters come into contact and cut, the excessive collision force between the blades after contact will damage the blades. If they do not come into contact, it will affect the cutting quality. Furthermore, after cutting, the workers need to manually remove the cut woven bags, resulting in a large workload for the workers. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a positioning and cutting device for woven bag production.

[0005] An embodiment of this utility model provides a positioning and cutting device for woven bag production, comprising:

[0006] Two connecting plates are provided, on which a conveying assembly and a pressing assembly are mounted. A cutting assembly is also mounted on the two connecting plates.

[0008] Furthermore, the conveying assembly includes two drive rollers rotatably connected between connecting plates, the two drive rollers being driven by a conveyor belt, and a plurality of idler rollers rotatably connected between the two connecting plates. A first motor is fixedly installed on the side wall of one of the connecting plates, and the rotating end of the first motor is fixedly connected to one of the drive rollers.

[0009] Furthermore, the pressing assembly includes a gantry frame fixedly connected between two connecting plates. A cylinder is fixedly installed on the upper surface of the gantry frame. The output end of the cylinder slides through the gantry frame and is fixedly connected to a connecting frame. Two sliding blocks are slidably connected to the connecting frame. A pressing roller is rotatably connected between the two sliding blocks. Two second springs are fixedly connected to the connecting frame. The two second springs are respectively fixedly connected to the two sliding blocks. A fixing frame is fixedly connected to the connecting frame.

[0011] Furthermore, the lever is provided with an anti-slip pad layer, which is made of soft rubber.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. First, the woven bags are laid on the conveyor belt. Then, the cylinder starts working, causing the pressing rollers and pressing wheels to contact the woven bags. Then, the first motor starts working, causing the conveyor belt to move, so that the woven bags can be transported smoothly, improving the stability of the woven bag transport.

[0014] 2. Once the woven bag has been conveyed to the specified length, the second motor starts working, which in turn starts the bidirectional screw, bringing the two cutting blades closer together to perform the cutting operation. The first spring and damper can buffer the two cutting blades, preventing them from directly contacting each other and causing damage, thus improving cutting accuracy and extending the equipment's lifespan.

[0015] 3. When the cutting blades are close to each other, the lever is rotated counterclockwise until it is parallel to the ground to lift the woven bag.

The device includes multiple first springs 11 fixedly connected to the lifting plate 7, a cutting blade 8 fixedly connected to the multiple first springs 11, and multiple dampers fixedly connected to the lifting plate 7. The dampers are existing technology and have the functions of shock absorption and energy absorption, which help to improve the service life of the equipment and reduce adverse effects such as noise and vibration. They will not be described in detail here. The multiple dampers are all fixedly connected to the cutting blade 8. Multiple support plates 12 are fixedly connected between the two connecting plates 1. The lower end face of the multiple support plates 12 is provided with anti-slip texture, which improves the stability of the device. A toggle component is installed on one of the support plates 12.

[0023] The actuation assembly includes an actuation rod 13 rotatably connected to a support plate 12. The actuation rod 13 is provided with an anti-slip pad made of soft rubber, which increases the friction between the actuation rod 13 and the woven bag, making it easier to remove the woven bag from the device and improving the portability of the device. A rotating gear 14 is fixedly connected to the actuation rod 13. A rack 15 is fixedly connected to one of the lifting plates 7. The rotating gear 14 and the rack 15 mesh with each other. Multiple rotating rollers are rotatably connected between the two connecting plates 1. The rotating rollers can lift the woven bag. The conveying assembly includes two active rollers 2 rotatably connected between the connecting plates 1. The two active rollers 2 are driven by a conveyor belt 3. Multiple idler rollers 4 are rotatably connected between the two connecting plates 1. A first motor 5 is fixedly installed on the side wall of one of the connecting plates 1. The rotating end of the first motor 5 is fixedly connected to one of the active rollers 2.

[0024] The pressing assembly includes a gantry frame 16 fixedly connected between two connecting plates 1. A cylinder 17 is fixedly installed on the upper end face of the gantry frame 16. The output end of the cylinder 17 slides through the gantry frame 16 and is fixedly connected to a connecting frame. Two sliding blocks are slidably connected to the connecting frame. A pressing roller 18 is rotatably connected between the two sliding blocks. Two second springs 19 are fixedly connected to the connecting frame. The two second springs 19 are respectively fixedly connected to the two sliding blocks. A fixing frame 20 is fixedly connected to the connecting frame. Columns are fixedly connected to the upper end faces of both connecting plates 1. The fixing frame 20 is slidably connected to the two columns.

[0026] The detailed working process of this utility model is as follows:

[0027] First, the user places the device in the designated processing area, then lays the woven bags on the conveyor belt 3. Next, cylinder 17 starts working, causing the pressing rollers 18 and 22 to contact the woven bags. Then, the first motor 5 starts working, causing the conveyor belt 3 to move, ensuring smooth transport of the woven bags and improving transport stability. Once the woven bags have been transported to the designated length, the second motor 10 starts working, causing the bidirectional screw 9 to operate, bringing the two lifting plates 7 closer together. This brings the cutting blades 8 closer together, achieving the cutting operation. The first spring... Spring 11 and damper can buffer the two cutting blades 8, preventing them from directly contacting and damaging them, thus improving cutting accuracy and extending equipment life. When the cutting blades 8 approach each other, rack 15 moves upward, causing rotating gear 14 to rotate counterclockwise. The actuating rod 13 can then rotate counterclockwise to be parallel to the ground, lifting the woven bag. After cutting, rack 15 moves downward, and actuating rod 13 rotates clockwise, thus actuating the woven bag and removing it from the device. This allows for the rapid discharge of the cut woven strip, improving the portability of the device.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it.
