Description

Technical Field

[0001] The utility model relates to the technical field of film lamination of packaging paper boxes, in particular to a film lamination positioning and cutting device for packaging paper boxes. Background Art

[0002] During the production process of packaging cartons, a layer of film needs to be coated on the surface of the packaging cartons to improve the wear resistance and waterproofness of the packaging cartons. After the packaging cartons are coated with the film, a special device needs to be used to cut off the excess film. For example, a packaging carton coating positioning and cutting device with the publication number of "CN215751028U" is disclosed. Through the provided pressing plate, when the packaging carton passes through the conveyor belt and reaches the pressing plate, the packaging carton is lifted up against the pressing plate. The upward movement of the pressing plate drives the long strip to move upward on the long column and the straight column through the slide groove. While the long strip moves upward, the small spring is tightened. The small spring is tightened under the interaction force so that the pressing plate presses the coated packaging carton. It prevents bubbles from being generated during the lamination of packaging cartons and prevents the packaging cartons from shaking, effectively solving the problem of being unable to make adjustments when facing packaging cartons of different heights, and the problem of being unable to immediately expel bubbles when air enters during lamination, and the problem of manually expelling bubbles later is time-consuming and may cause damage to the lamination, thereby wasting materials. The handle is pulled to drive the pressure strip to move on the straight column through the movable groove, thereby driving the ceramic blade to cut the lamination on the packaging carton, and a large spring is set to pull the ceramic blade to automatically rebound, which is time-saving and convenient, and the ceramic blade is safer to operate, effectively protecting the safety of the operator.

[0003] When the above mechanism is in use, the handle is pulled to drive the pressure strip, so that the movable groove moves on the straight column, thereby driving the ceramic blade to cut the excess coating on the packaging carton. However, due to the lack of a structure to fix the packaging carton during the cutting process, the packaging carton is prone to deviation, and then the excess film of the packaging carton cannot be accurately cut, resulting in poor cutting effect.

[0004] Therefore, we proposed a packaging carton laminating positioning and cutting device that can solve the above problems well. Utility Model Content

[0005] The purpose of the utility model is to provide a packaging paper box laminating positioning and cutting device to solve the problem proposed in the above-mentioned background technology that the packaging paper box is easily offset due to the defect of the structure for fixing the packaging paper box during the cutting process, and then the excess film of the packaging paper box cannot be accurately cut, resulting in poor cutting effect.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a packaging paper box laminating positioning and cutting device, comprising a bracket, the top of the bracket is bolted to a hydraulic cylinder, and the lower end of the hydraulic cylinder passes through the inside of the bracket, and a pressing plate is slidably connected to the upper inside of the bracket, and the top of the pressing plate is fixedly connected to the output end of the hydraulic cylinder;

[0007] A packaging paper box laminating positioning and cutting device, further comprising:

[0008] A conveyor belt assembly is installed below the inner side of the bracket to transport the packaging carton, and a motor is bolted to the lower left side of the bracket, and the output end of the motor is fixedly connected to the shaft end of the conveyor belt assembly;

[0009] A blade is installed in the middle of the bottom of the pressure plate, and fixed blocks are fixed through the left and right sides of the inner wall of the bracket, and a rack is slidably connected inside the fixed block, and a driving gear is rotatably connected above the rack inside the fixed block;

[0010] A traction rope is passed between the driving gear and the pressure plate, and a vortex spring is installed between the shaft end of the driving gear and the inner wall of the fixed block. A box body is symmetrically arranged on the inner side of the bracket above the conveyor belt assembly;

[0011] Clamping plates are fixed on opposite sides of the two box bodies, and movable plates are arranged on opposite sides of the two clamping plates. Side surfaces of the two box bodies are fixedly connected to ends of two racks.

[0012] Preferably, one end of the traction rope is wound around the shaft end of the driving gear, and the other end of the traction rope is fixed to the top of the pressure plate, the driving gear and the rack are meshed, and both ends of the rack pass through the interior of the fixed block.

[0013] Preferably, the inside of the clamping plate is slidably connected with a connecting rod, and the right ends of the two connecting rods are fixedly connected to the left side of the movable plate, and a buffer spring is installed between the outer sides of the two connecting rods and the inner wall of the clamping plate, and the left ends of the two connecting rods are fixedly connected to a guide plate.

[0014] Preferably, one end of the inner wall of the two boxes is provided with an air bag, and a suction pipe is fixed to the side of the air bag.

[0015] Preferably, through tubes are fixed to the bottom of the pressure plate symmetrically about the center point of the blade, and air outlets are opened at equal intervals at the bottom of the two through tubes, and an air supply pipe is fixedly connected between the airbag and the through tubes.

[0017] Preferably, one-way valves are installed inside the air intake pipe and the air delivery pipe.

[0018] Compared with the prior art, the beneficial effects of the utility model are as follows: the packaging carton laminating positioning and cutting device drives the pressing plate to move downward through the hydraulic rod, and at the same time uses the traction rope to pull the driving gear to rotate and drive the meshing rack to move. At this time, the two clamping plates move relative to each other to clamp and fix the packaging carton on the conveyor belt assembly, thereby preventing the packaging carton from deviating and affecting the cutting effect when the film on the packaging carton is cut. The specific contents are as follows:

[0019] (1) The pressure plate is driven downward by a hydraulic cylinder, and the driving gear is pulled by a traction rope to rotate. At this time, the two racks move relative to each other, and drive the two clamping plates to move relative to each other to clamp and fix the packaging carton on the conveyor belt assembly, thereby preventing the packaging carton from deviating when the film on the packaging carton is cut, thereby affecting the cutting effect;

[0020] Furthermore, as the two clamping plates move relative to each other, the two movable plates come into contact with the packaging carton and move under pressure, while the connecting rod moves and stretches the buffer spring, thereby utilizing the elastic force of the return spring to effectively buffer the clamping force, thereby preventing the packaging carton from being damaged due to excessive clamping force.

[0021] (2) When the pressing plate moves downward, it can press the film-coated packaging carton, thereby expelling bubbles on the packaging carton film, and at the same time, the blade can be used to cut off the excess film.

[0022] (3) When the connecting rod moves, it drives the guide plate to squeeze the airbag, so that the gas released by the airbag under pressure enters the through pipe through the air pipe and is blown out from the air outlet, thereby preventing the excess film from sticking to the blade when cutting the excess film;

[0023] (4) When the guide plate no longer squeezes the airbag, the airbag returns to its original state and automatically replenishes gas through the air intake pipe, making it easier to use next time. At the same time, a one-way valve is provided so that external gas can only enter the airbag from the air intake pipe, and the gas in the airbag can only enter the through pipe from the gas supply pipe, thereby preventing gas turbulence.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figure 1-Figure 7 , the utility model provides the following technical solutions: a packaging paper box laminating positioning and cutting device;

[0034] Embodiment 1: In order to solve the problem in the prior art that the packaging paper box is easily offset due to the structure of fixing the packaging paper box during the cutting process, and then the excess film of the packaging paper box cannot be accurately cut, resulting in poor cutting effect, the following solution is disclosed, and specific reference is made to Figure 1-Figure 5 and Figure 7 As shown, it includes a bracket 1, the top of the bracket 1 is bolted with a hydraulic cylinder 2, and the lower end of the hydraulic cylinder 2 passes through the inside of the bracket 1, and a pressure plate 4 is slidably connected to the upper inside of the bracket 1, and the top of the pressure plate 4 is fixedly connected to the output end of the hydraulic cylinder 2;

[0035] It also includes: a conveyor belt assembly 3 is installed at the lower part of the inner side of the bracket 1 for conveying the packaging carton, and a motor is bolted to the lower part of the left side of the bracket 1, and the output end of the motor is fixedly connected to the shaft end of the conveyor belt assembly 3; a blade 5 is installed at the middle position of the bottom of the pressing plate 4, and a fixed block 6 is fixed through the left and right sides of the inner wall of the bracket 1, and a rack 7 is slidably connected inside the fixed block 6, and a driving gear 11 is rotatably connected above the rack 7 inside the fixed block 6; a traction rope 13 is passed between the driving gear 11 and the pressing plate 4, and the shaft end of the driving gear 11 is connected to the A vortex spring 12 is installed between the inner walls of the fixed block 6, and a box body 8 is symmetrically arranged on the inner side of the bracket 1 above the conveyor belt assembly 3; clamping plates 10 are fixed to the opposite surfaces of the two box bodies 8, and movable plates 9 are arranged on the opposite surfaces of the two clamping plates 10, and the side surfaces of the two box bodies 8 are fixedly connected to the ends of the two racks 7, one end of the traction rope 13 is wound around the shaft end of the driving gear 11, and the other end of the traction rope 13 is fixed to the top of the pressing plate 4, the driving gear 11 is meshed with the rack 7, and both ends of the rack 7 pass through the interior of the fixed block 6;

[0036] When in use, the motor is started, and the motor drives the conveyor belt assembly 3 to rotate, so that the packaging box that has been coated with film can be transported. When it is transported to the position between the two clamping plates 10, the hydraulic cylinder 2 is started, and the hydraulic cylinder 2 drives the pressure plate 4 to move downward, and uses the traction rope 13 to pull the driving gear 11 to rotate forward, so that the two driving gears 11 drive the two meshing racks 7 to move relative to each other, and drive the two box bodies 8 and the clamping plates 10 to move relative to each other to clamp and fix the packaging paper box on the conveyor belt assembly 3, thereby preventing the film on the packaging paper box from being cut. At this time, the packaging carton is offset and affects the cutting effect. At the same time, the pressure plate 4 drives the blade 5 to move downward to cut the excess film on the packaging carton. Then, after the cutting is completed, the pressure plate 4 and the blade 5 are driven upward by the hydraulic cylinder 2. At this time, the traction rope 13 no longer pulls the driving gear 11 to rotate, so that the driving gear 11 is reversed and reset under the stored force of the vortex spring 12, and drives the meshing rack 7 to move. At this time, the two racks 7 move in opposite directions and drive the two box bodies 8 and the clamping plate 10 to move in opposite directions, thereby releasing the fixation of the packaging carton.

[0037] Embodiment 2: Different from Embodiment 1, this embodiment utilizes the elastic force of the buffer spring 20 to effectively buffer the clamping force and prevent the packaging paper box from being damaged. For details, refer to Figure 5 As shown, the inside of the clamping plate 10 is slidably connected with a connecting rod 14, and the right ends of the two connecting rods 14 are fixedly connected to the left side of the movable plate 9, and a buffer spring 20 is installed between the outer sides of the two connecting rods 14 and the inner wall of the clamping plate 10, and the left ends of the two connecting rods 14 are fixedly connected to the guide plate 15;

[0038] As the two clamping plates 10 move relative to each other, the two movable plates 9 come into contact with the packaging carton and move due to compression. At this time, the connecting rod 14 moves and stretches the buffer spring 20, and then the reverse force generated by the elastic force of the buffer spring 20 is utilized to effectively buffer the clamping force, thereby preventing the packaging carton from being damaged due to excessive clamping force.

[0039] Embodiment 3: Different from Embodiment 2, this embodiment utilizes the gas released by the airbag 16 under pressure to prevent the cut film from adhering to the blade 5 and affecting the next cutting. For details, refer to Figure 1 , Figure 5 and Figure 6 As shown, one end of the inner wall of the two box bodies 8 is provided with an air bag 16, and an air suction pipe 17 is fixed to the side of the air bag 16, and the end of the air suction pipe 17 away from the air bag 16 passes through the interior of the box body 8, and the air bag 16 is connected to the interior of the through pipe 21 through the air supply pipe 18, and the inside of the air suction pipe 17 and the air supply pipe 18 are both installed with a one-way valve 19, and the bottom of the pressure plate 4 is symmetrically fixed with through pipes 21 about the center point of the blade 5, and the bottoms of the two through pipes 21 are provided with air outlets 22 at equal intervals, and the air supply pipe 18 is fixedly connected between the air bag 16 and the through pipe 21;

[0040] When the connecting rod 14 moves, it will drive the guide plate 15 to squeeze the airbag 16, so that the gas released by the pressure of the airbag 16 enters the through pipe 21 through the air supply pipe 18, and then blows out to the blade 5 from the air outlet 22, thereby preventing the excess film from sticking to the blade 5 and affecting the next cutting when the excess film is cut. Then, when the cutting is completed, the connecting rod 14 is reset under the elastic force of the buffer spring 20, and drives the guide plate 15 to reset, so that it no longer squeezes the airbag 16. At this time, the airbag 16 restores its original state by itself, and uses the suction pipe 17 to automatically replenish the gas, which is convenient for the next use. At the same time, the one-way valve 19 is set, so that the outside gas only enters the airbag 16 from the suction pipe 17, and the gas in the airbag 16 only enters the through pipe 21 from the air supply pipe 18, thereby preventing gas turbulence.

[0041] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
