[0001] The application relates to the technical field of cutting devices, in particular to a film cutting device for ton bags. BACKGROUND

[0002] In a ton bag production line, the film as an important packaging material directly affects the efficiency of the subsequent packaging process and the quality of the finished product. The traditional film cutting device adopts a straight conveying mode of a conveying belt. Although automatic production is achieved to a certain extent, the following problems exist.

[0003] Film position deviation: during the conveying process, due to the factors such as the weight of the film itself and the uneven speed of the conveying belt, the film is prone to position deviation, which affects the cutting precision.

[0004] Film stacking after cutting: after cutting, the film often directly falls into the collection area due to the lack of effective arrangement, which easily causes mutual stacking and increases the difficulty of subsequent separation. CONTENT OF THE INVENTION

[0005] The application aims to solve the problems of the existing film cutting device, which is prone to position deviation during conveying and affects the cutting precision, and causes film stacking after cutting due to the lack of effective arrangement.

[0006] To solve the above technical problems, the application provides a film cutting device for ton bags, which comprises a rack, a pullable material frame arranged in the rack, a traction assembly, a deviation correction assembly and a cutting assembly arranged in sequence on the top of the rack for processing the film, the traction assembly is located at the front end of the top of the rack, a material pushing assembly is further arranged on the upper part of the rack, the material pushing assembly is located behind the cutting assembly, the material pushing assembly comprises a third air cylinder, a pull frame and a support, the support is fixedly arranged on the upper part of the rack, the pull frame is sleeved on the upper part of the support, and the third air cylinder is arranged on the upper part of the rack and connected with the pull frame.

[0007] Since the cutting device is designed with the traction assembly, the deviation correction assembly, the cutting assembly and the material pushing assembly, the feeding and deviation prevention of the film can be realized through the traction assembly and the deviation correction assembly, and the cutting and anti-stacking of the film can be realized through the cutting assembly and the material pushing assembly, thereby solving the problems of the existing film cutting device, which is prone to position deviation during conveying and affects the cutting precision, and causes film stacking after cutting due to the lack of effective arrangement.

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application. EMBODIMENT

[0017] The present application relates to a kind of rubber sheet cutting device for ton bag, such as Figures 1-7As shown, the cutting device comprises a rack 1 as the support structure of the whole device, made of square tube or angle iron to ensure stability and durability, the upper end of the rack 1 is arranged with a material roller 2 for feeding and can be disassembled, so as to facilitate quick replacement of different specifications or batches of film, improve production flexibility, the inside of the rack 1 is arranged with a pullable material frame 3, so as to be used for receiving the cut film, and its structure design is convenient for taking out and cleaning, the top of the rack 1 is arranged with a traction assembly 4, a deviation correction assembly 5 and a cutting assembly 6 in turn, the traction assembly 4 is located at the front end of the top of the rack 1, and advances the film at a constant speed through a belt structure, so as to ensure the stable movement of the film before cutting, the deviation correction assembly 5 is followed by the traction assembly 4, adopts a baffle type structure, and physically corrects the film to ensure that the film is in a predetermined position before cutting, reduces the position deviation, the cutting assembly 6 adopts a vertical lifting knife cutting mode, and quickly and accurately cuts the film according to the preset parameters, in order to make the film accurately fall into the material frame 3, the upper part of the rack 1 is further arranged with a material pushing assembly 7, the material pushing assembly 7 is located behind the cutting assembly 6, and the cut film is pushed into the material frame 3 through a horizontally pulled push plate structure, effectively avoiding the accumulation of the film, and ensuring that each piece of film can be independently and neatly fallen into the material frame 3.

[0018] The traction assembly 4 includes a motor 13, a conveying belt 12, a first cylinder 8, a compression roller 11, a sliding rail 9, and a sliding block 10. The conveying belt 12 is horizontally arranged on the upper part of the frame 1 to serve as a carrier for film conveying. The material and surface treatment of the conveying belt 12 need to be selected according to the material and characteristics of the film to ensure good friction and wear resistance. The motor 13 is arranged inside the frame 1 and connected to the conveying belt 12 through a transmission device (such as a belt pulley, chain, etc.) to drive the conveying belt 12 to move horizontally, thereby driving the film to advance. The compression roller 11 is arranged on the upper part of the conveying belt 12 to form an abutment with the film and the conveying belt 12, ensuring that the film remains stable during conveying. The material and diameter of the compression roller 11 need to be selected according to the thickness and material of the film to avoid damaging the film. The sliding rail 9 is arranged on the upper part of the frame 1 to provide a sliding track for the sliding block 10 in the vertical direction. The design of the sliding rail 9 needs to ensure that the sliding block 10 can move vertically smoothly and accurately, with good wear resistance and corrosion resistance. The sliding block 10 is connected to both ends of the compression roller 11 and can slide vertically on the sliding rail 9. The design of the sliding block 10 needs to ensure good cooperation with the sliding rail 9, as well as sufficient carrying capacity and stability. The first cylinder 8 is arranged on the upper part of the frame 1 and connected to the sliding block 10 through a piston rod to drive the sliding block 10 and the compression roller 11 to move vertically. The selection of the first cylinder 8 needs to be determined according to factors such as the weight of the compression roller 11, the required pressure, and the movement speed. When the motor 13 is started, it drives the conveying belt 12 to move horizontally through the transmission device, driving the film to advance. At the same time, the first cylinder 8 drives the sliding block 10 and the compression roller 11 to move vertically on the sliding rail 9, forming a certain pressure between the compression roller 11 and the film, ensuring that the film remains stable during conveying. By adjusting the stroke of the first cylinder 8, the film conveying pressure can be controlled. By adjusting the speed of the motor 13, the film conveying speed can be controlled, thereby meeting the traction requirements of films of different thicknesses and materials.

[0019] The deviation correction assembly 5 includes a support rod 21 and a clamping plate 20. The support rod 21 is horizontally arranged between the frames 1 on the upper part of the conveying belt 12 as a support structure for the clamping plate 20. The design of the support rod 21 needs to ensure sufficient strength and stability to withstand the weight of the clamping plate 20 and the impact force during film movement. The clamping plate 20 is symmetrically arranged on the upper part of the support rod 21 with a manually adjustable spacing. The clamping plate 20 has a passage for the film to pass through, and the width of the passage can be manually adjusted according to the width of the film. The material of the clamping plate 20 needs to have a certain elasticity and wear resistance to ensure good contact and friction with the film while avoiding damage to the film. When the film moves on the conveying belt 12, if it deviates from the position, it will touch one side of the clamping plate 20. Since the spacing of the clamping plate 20 is manually adjustable, the width of the clamping plate 20 can be adjusted to allow the film to automatically return to the predetermined position after being affected by the force of the clamping plate 20, thereby achieving deviation correction of the film.

[0020] The cutting assembly 6 comprises a support plate 15, a second cylinder 14, a frame plate 16, a pressing strip 18, a cutter body 17 and a supporting strip 19. The support plate 15 is horizontally arranged on the upper portion of the frame 1 and serves as a support structure of the whole cutting assembly 6. The design of the support plate 15 needs to ensure sufficient strength and stability to withstand the impact force and vibration generated during the cutting process. The second cylinder 14 is arranged at the central position of the upper portion of the support plate 15 and is vertically installed downward. The second cylinder 14 is connected with the frame plate 16 through a piston rod to drive the frame plate 16 and the cutter body 17 to move vertically. The selection of the second cylinder 14 needs to be determined according to factors such as cutting force, cutting speed and movement stroke. The frame plate 16 is connected with the lower end of the second cylinder 14 and serves as a mounting carrier of the cutter body 17. The design of the frame plate 16 needs to ensure sufficient rigidity and precision to ensure stable movement and cutting precision of the cutter body 17. The cutter body 17 is arranged at the lower end of the frame plate 16 and serves as the main component for cutting the film. The material and shape of the cutter body 17 need to be selected and designed according to the material and thickness of the film to ensure the accuracy and stability of the cutting. The pressing strip 18 is vertically and slidingly connected inside the frame plate 16 and is used to press and fix the film. The material of the pressing strip 18 needs to have certain elasticity and wear resistance to avoid damaging the film. The vertical sliding connection between the pressing strip 18 and the frame plate 16 can be achieved through structures such as sliding rails 9 and sliding blocks 10. The supporting strip 19 is arranged on the upper portion of the frame 1 and corresponds to the pressing strip 18 to support the film. The design of the supporting strip 19 needs to ensure good cooperation with the pressing strip 18 and sufficient carrying capacity and stability. The supporting strip 19 and the frame 1 can be fixedly connected through bolts or welding. When the film is conveyed to the cutting position, the supporting strip 19 supports the film. At this time, the second cylinder 14 drives the frame plate 16 and the cutter body 17 to move vertically downward, and the pressing strip 18 slides vertically inside the frame plate 16 to press and fix the film. When the cutter body 17 contacts the film, the film is cut. After the cutting is completed, the second cylinder 14 drives the frame plate 16 and the cutter body 17 to move vertically upward, and the pressing strip 18 also rises, and the film is released.

[0021] The pushing assembly 7 comprises a third cylinder 24, a pulling frame 23 and a support 22. The support 22 is fixedly arranged on the upper portion of the frame 1 and serves as a temporary bearing platform for the cut film. The design of the support 22 needs to ensure sufficient bearing capacity and stability to withstand the impact force generated during the cutting process and the weight of the film. The pulling frame 23 is sleeved on the upper portion of the support 22 and is used to push the film under the drive of the third cylinder 24. The shape and size of the pulling frame 23 need to match the support 22 to ensure that it can closely fit the film during the pushing process to avoid damage to the film. The third cylinder 24 is arranged on the upper portion of the frame 1 and is connected with the pulling frame 23 to pull the pulling frame 23 to slide back and forth. The selection of the third cylinder 24 needs to be determined according to the pushing distance, speed and required force, etc. to ensure the stability and accuracy of the pushing process. When the cutting assembly 6 completes the cutting of the film, the cut film falls on the support 22. At this time, the third cylinder 24 is started to drive the pulling frame 23 to slide back and forth along the track set on the upper portion of the frame 1. The pulling frame 23 pushes the film on the support 22 into the material frame 3 during the sliding process. After the pushing is completed, the third cylinder 24 drives the pulling frame 23 to return to the initial position, waiting for the next pushing operation.
