Description

Technical Field

[0001] The present invention relates to the technical field of the design and manufacture of white liquor packaging boxes, and specifically relates to a trimming mechanism and a trimming method for a packaging box with anti-warping edges. Background Technique

[0002] White liquor packaging boxes play a crucial role in protecting the products. They can effectively prevent white liquor from being affected by external factors such as collision, light, and temperature changes during transportation and storage. Most white liquor products use glass bottle containers, and when designing the packaging, functions such as shock resistance, anti-falling, and anti-breaking need to be considered to ensure the safety of the products. In addition, the packaging boxes usually adopt thick cardboard boxes with internal partitions, which can play a buffering role, block light, and protect the liquor quality from being affected by external factors. Currently, the packaging materials of white liquor packaging boxes generally use packaging boxes made of special paper. When processing the packaging materials, cutting is required to make their sizes meet the required dimensions.

[0003] The existing trimming mechanisms for packaging boxes are inconvenient to clamp and fix according to the width of the original packaging materials, and the two sides of the packaging materials are prone to warping during the trimming process, resulting in easy deviation during the trimming process. Therefore, they do not meet the existing requirements. For this reason, we propose a trimming mechanism and a trimming method for a packaging box with anti-warping edges. Summary of the Invention

[0008] Preferably, the driving mechanism includes slide rails, sliding seats, sliding plates and threaded rods. On both sides of the bottom end of the conveyor plate, and at the front and rear ends where the two limiting holes are close to each other, there are fixed slide rails, and the sliding seats are slidably connected to the outer surfaces of the slide rails.

[0009] Preferably, the sliding plate is arranged in a T shape and is slidably connected between the two slide rails. The bottom end of the clamping plate slidably penetrates through the limiting hole and is fixedly connected to one end of the sliding plate. On both sides of the end of the sliding plate away from the clamping plate, there are connecting rods hinged between the two sliding seats.

[0010] Preferably, on the bottom ends of the two sliding plates, on the sides away from each other, there are fixed plates fixedly connected. On both sides of the bottom end of the conveyor plate, there are fixed seats corresponding to the fixed plates.

On both sides of the inner wall of the U-shaped seat, there are installation seats connected by connecting rods. At both ends of the cutting knife, there are connecting blocks fixedly connected, and the two connecting blocks are respectively inserted into the corresponding installation seats.

[0012] Preferably, inside one end of the U-shaped seat, there is a driving cavity, and one of the connecting rods movably penetrates through the driving cavity and extends to the outside of the U-shaped seat.

[0015] A trimming method for a trimming mechanism of a packaging box with anti-warping edges, comprising the following steps:

[0016] S1: Place the packaging material on the conveyor plate, and position the position of the packaging material to be cut above the cutting hole. Then, by rotating the threaded rods on both sides of the bottom end of the conveyor plate, while the threaded rods rotate, they thread through the fixed seats and rotate in the fixed plates, thereby pushing the sliding plates on both sides to drive the clamping plates to move towards each other along the limiting holes. At the same time, both ends of the sliding plates are hinged to the sliding seats through connecting rods, so that the clamping plates are driven to move smoothly along the slide rails, and thus the packaging material is clamped and fixed on the upper end of the conveyor plate according to its size;

[0017] S2: The stepping motor drives the lead screw to rotate. While the lead screw rotates, the connecting seat on its outer surface is threaded and moves along the side groove towards the bottom end of the top plate under the limitation of the slide bar, and the position of the packaging material to be cut corresponds to the cutting knife;

[0018] S3: The first oil cylinder drives the top plate provided with the cutting knife to move downward. While the top plate moves downward, it drives the pressing plate to move downward. The pressing plate is elastically connected to the second spring inside the fixed sleeve through the mounting rod at the upper end, so that the pressing plate presses the edge of the packaging material to be cut, avoiding warping on both sides during cutting and causing deviation during the edge-cutting process;

[0019] S4: The second oil cylinder pushes the cutting knife to perform a horizontal cut along the strip-shaped hole, and thus the stable cutting of the packaging material can be completed. Start the dust suction fan, suck the cut debris from the dust suction port into the dust collection box for collection, avoid excessive debris from causing discomfort to the user, and the dust collection box can be pulled out for cleaning very conveniently.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In the present invention, the position of the packaging material to be cut is placed above the cutting hole. Then, by rotating the threaded rods on both sides of the bottom end of the conveyor plate, while the threaded rods rotate, they thread through the fixed seats and rotate in the fixed plates, thereby pushing the sliding plates on both sides to drive the clamping plates to move towards each other along the limiting holes. At the same time, both ends of the sliding plates are hinged to the sliding seats through connecting rods, so that the clamping plates are driven to move smoothly along the slide rails, and thus the packaging material is clamped and fixed on the upper end of the conveyor plate according to its size;

[0022] 2. By pulling the connecting rod that can move on one side of the U-shaped seat in the present invention, the limiting plate presses the first spring to compress, and the movable connecting rod drives the mounting seat to move away from the fixed mounting seat on the other side. Then, the connecting block on one side of the cutting knife is inserted into the fixed mounting seat. Next, the pulling of the movable connecting rod on the other side is released, so that the first spring releases its elastic force, and then the mounting seat on the movable side is pushed to be clamped on the outer surface of the connecting block on the other side of the cutting knife, thereby installing and fixing the cutting knife, which is convenient for replacing the worn cutting knife during long-term use;

[0023] 3. By starting the first oil cylinder to drive the top plate provided with the cutting knife to move downward, while the top plate moves downward, it drives the pressure plate to move downward. The pressure plate is elastically connected to the second spring inside the fixed sleeve through the mounting rod at the upper end, so that the pressure plate presses the edge to be cut of the packaging material, avoiding warping on both sides during cutting and resulting in deviation during the cutting edge process.

Below one end of both side grooves 101, a first oil cylinder 9 is supported and connected through a support plate 8. A top plate 10 is fixedly connected between the tops of the two first oil cylinders 9. One side of the upper end of the top plate 10 is driven and connected to a mounting mechanism 12 through a second oil cylinder 11. A cutting knife 1204 is installed inside the mounting mechanism 12. A strip-shaped hole 1001 is opened in the middle of the top plate 10, and one end of the cutting knife 1204 penetrates the strip-shaped hole 1001 and extends to the bottom end of the top plate 10. One side of the bottom end of the top plate 10 close to the conveyor plate 2 and on one side of the strip-shaped hole 1001, a pressure plate 15 is movably connected;

[0033] A dust suction fan 18 is provided on the side of the workbench 1 away from the conveyor plate 2. A dust suction port 19 is fixedly connected to one side of the upper end of the dust suction fan 18 close to the cutting knife 1204.

[0034] Inside the side groove 101 on one side, a lead screw 4 is driven and connected by a stepping motor 3. Inside the side groove 101 on the other side, a slide bar is fixedly connected. One connecting seat 5 is threadedly connected to the outer surface of the lead screw 4, and the other connecting seat 5 is slidably connected to the outer surface of the slide bar. By starting the stepping motor 3 to drive the lead screw 4 to rotate, while the lead screw 4 rotates, the connecting seat 5 on its outer surface is threaded to move along the side groove 101 towards the bottom end of the top plate 10 under the limitation of the slide bar, and the position of the packaging material to be cut is made to correspond to the cutting knife 1204.

[0035] The driving mechanism 7 includes a slide rail 701, a slide seat 702, a sliding plate 703, and a threaded rod 707. On both sides of the bottom end of the transfer plate 2, and at the front and back of the two limiting holes 202 close to each other, slide rails 701 are fixedly connected. The slide seat 702 is slidably connected to the outer surface of the slide rail 701. The sliding plate 703 is arranged in a T shape and is slidably connected between the two slide rails 701. The bottom end of the clamping plate 6 slidably penetrates through the limiting hole 202 and is fixedly connected to one end of the sliding plate 703. On both sides of the end of the sliding plate 703 away from the clamping plate 6, connecting rods 704 are hinged between the two slide seats 702. On the bottom ends of the two sliding plates 703 away from each other, fixing plates 706 are fixedly connected. On both sides of the bottom end of the transfer plate 2, fixed seats 705 corresponding to the fixing plates 706 are fixedly connected. On the sides of the two fixing plates 706 away from each other, threaded rods 707 that penetrate through the fixed seats 705 through rotation shafts and extend to the outside of the fixed seats 705 are rotatably connected.

[0036] By rotating the threaded rods 707 on both sides of the bottom end of the transfer plate 2, while the threaded rods 707 rotate, they threadedly penetrate through the fixed seats 705 and rotate with the fixing plates 706, thereby pushing the sliding plates 703 on both sides to drive the clamping plates 6 to move towards each other along the limiting holes 202. Moreover, the two ends of the sliding plate 703 are hinged to the slide seats 702 through the connecting rods 704, enabling it to drive the clamping plate 6 to move smoothly along the slide rail 701, so as to clamp and fix the upper end of the transfer plate 2 according to the size of the packaging material.

[0037] The installation mechanism 12 includes a U-shaped seat 1201, a connecting rod 1202 and an installation seat 1203. Both sides of the inner wall of the U-shaped seat 1201 are connected with the installation seat 1203 through the connecting rod 1202. Both ends of the cutting knife 1204 are fixedly connected with connecting blocks 1205. The two connecting blocks 1205 are respectively inserted into the corresponding installation seats 1203. A driving cavity 120101 is formed inside one end of the U-shaped seat 1201. One side connecting rod 1202 movably penetrates through the driving cavity 120101 and extends to the outside of the U-shaped seat 1201. A limiting plate 1206 is fixedly connected to the outer surface of the connecting rod 1202 at one end inside the driving cavity 120101.

[0038] By pulling the movable connecting rod 1202 on one side of the U-shaped seat 1201, the limiting plate 1206 is made to squeeze the first spring 1207 to compress, and the movable connecting rod 1202 drives the installation seat 1203 to move away from the fixed installation seat 1203 on the other side. Then, the connecting block 1205 on one side of the cutting knife 1204 is inserted into the fixed installation seat 1203. Next, the pulling of the movable connecting rod 1202 on the other side is released, so that the first spring 1207 releases its elastic force, and then the installation seat 1203 on the movable side is pushed to be clamped on the outer surface of the connecting block 1205 on the other side of the cutting knife 1204, thereby installing and fixing the cutting knife 1204, which is convenient for replacing the worn cutting knife 1204 during long-term use.

[0039] A trimming method for a trimming mechanism of an anti-warping packaging box includes the following steps:

[0040] S1: Place the packaging material on the conveying plate 2, and position the position of the packaging material to be cut above the cutting hole 201. Then, by rotating the threaded rods 707 on both sides of the bottom end of the conveying plate 2, while the threaded rods 707 rotate, they thread through the fixed seat 705 and rotate in the fixed plate 706, thereby pushing the sliding plates 703 on both sides to drive the clamping plates 6 to move towards each other along the limiting holes 202. The two ends of the sliding plate 703 are hinged to the sliding seat 702 through the connecting rod 704, so as to drive the clamping plate 6 to move smoothly along the slide rail 701, and thus clamp and fix the packaging material on the upper end of the conveying plate 2 according to the size of the packaging material;

[0041] S2: After the packaging material is fixed on the conveying plate 2, start the stepping motor 3 to drive the lead screw 4 to rotate. While the lead screw 4 rotates, the connecting seat 5 on its outer surface is threaded to move along the side groove 101 towards the bottom end of the top plate 10 under the limitation of the slide bar, and the position of the packaging material to be cut corresponds to the cutting knife 1204;

[0042] S3: After the cutting position corresponds to the cutting knife 1204, start the first oil cylinder 9 to drive the top plate 10 provided with the cutting knife 1204 to move downward. While the top plate 10 moves downward, it drives the pressing plate 15 to move downward. The pressing plate 15 is elastically connected to the second spring 17 inside the fixed sleeve 13 through the mounting rod 14 at the upper end, so that the pressing plate 15 presses the edge of the packaging material to be cut, avoiding warping on both sides during cutting and causing deviation during the cutting edge process;

[0043] S4: After the pressing plate 15 presses, start the second oil cylinder 11 to push the cutting knife 1204 to perform a horizontal cut along the strip hole 1001, and the stable cutting of the packaging material can be completed. At the same time, start the dust suction fan 18 to suck the cut debris from the dust suction port 19 into the dust collection box 20 for collection, avoiding excessive debris and causing discomfort to the user. And through the pull-out setting of the dust collection box 20, the dust collection box 20 can be easily pulled out for cleaning.

[0044] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
