Description

Technical Field

[0001] The present application relates to the technical field of cutting devices, and in particular to a paper product cutting device. Background Art

[0002] Paper cutting equipment is a mechanical device used to cut paper. It can cut paper into specific sizes and shapes. The paper cutting device can quickly and accurately cut a large amount of paper, significantly improving work efficiency, while ensuring the uniformity of the cutting position. In actual operation, workers usually place the cut products neatly on one side.

[0003] Referring to the Chinese patent document with announcement number CN219276029U, the device is named as a paper product cutting device, which includes a frame, a first pressure roller, a second pressure roller, a cutter, a fixing part and an adjusting part. The first pressure roller and the second pressure roller are symmetrically mounted on the frame, and the first pressure roller is provided with a cutter in an annular array, and the second pressure roller is provided with a cutting groove in an annular array. The frame is also provided with an adjusting part, and the adjusting part is used to adjust the first pressure roller up and down. The fixing part is installed on the first pressure roller to fix the cutter. The distance between the cutters is adjusted according to the width of the paper product to achieve fixed-distance cutting. According to the thickness of the paper, the vertical axis distance between the first pressure roller and the second pressure roller is adjusted by the adjusting part, which effectively expands the use range of the device and can improve the work efficiency of paper product cutting.

[0004] Referring to the above technical solution, when cutting paper, the stacked paper is cut from top to bottom. After the cutting is completed, the paper on the upper part is easy to tilt backward as the cutting knife moves downward. Therefore, one end of the stacked paper needs to be blocked to prevent the finished product from scattering after cutting. After a long period of high-intensity work, the manual blocking effect is easy to be poor. At the same time, since the cutting position is close to the hand blocking position, safety hazards are easy to occur. Summary of the invention

[0005] In view of this, the present application provides a paper product cutting device, which is mainly used to solve the problem of accidental injury to workers by the cutting knife.

[0006] In order to solve the above technical problems, the present application provides a paper product cutting device, including a frame, a workbench, a pressing plate and a cutting blade. The pressing plate and the cutting blade are both driven by an externally connected driving member. The pressing plate is used to press the paper product. A sliding base is installed on the workbench. The sliding base is close to or away from the cutting blade. The sliding base is composed of a bottom plate, a top plate, a vertical plate and an inclined plate. The inclined plate is located close to the cutting blade. The vertical plate is parallel to the cutting blade. A rectangular groove is opened on the inclined plate. A baffle plate is connected to the rectangular groove through a hinge. The baffle plate is used to support the cut paper product. A pressing plate located above the bottom plate is slidably connected to the vertical plate. The pressing plate is parallel to the bottom plate. A first hydraulic block is fixedly installed on the pressing plate. A first hydraulic groove is opened on the bottom plate. A first pushing block is installed in the first hydraulic groove. The first pushing block is used to push the baffle plate to rotate.

[0007] By adopting the above technical solution, before cutting the stacked paper products, the pressing plate can press the paper products to prevent the uncut paper products from scattering, and the sliding base can move closer to or away from the cutting blade on the workbench. The paper products located on the upper part of the cut paper products may tilt backward due to the smooth surface and the inertia of the cutting blade, and the baffle plate can support and bear the cut paper products.

[0008] When the pressing plate is pressed downward, the first hydraulic block can output hydraulic pressure into the first hydraulic groove, thereby driving the first pushing block to approach the baffle plate, so that the baffle plate is perpendicular to the bottom plate, and the tilted stack of paper products is sorted. The baffle plate acts as the staff's hand to complete the sorting of the tilted paper products.

[0009] Optionally, a through slot is provided on the workbench and is located directly below the cutting blade. An opening and closing plate is installed on the through slot via a torsion spring, and a waste collection box corresponding to the opening and closing plate is installed at the bottom of the workbench.

[0010] By adopting the above technical solution, under the action of the torsion force of the torsion spring, the opening and closing plate is in a closed state. After the cutting blade cuts off the scraps of paper products, the cutting blade is retracted and the opening and closing plate can be manually opened, and the waste collection box can directly collect the scraps.

[0011] Optionally, a first limiting component for limiting the opening and closing plate is provided on the workbench, and the first limiting component includes a second hydraulic groove opened on the workbench, a second clamping column for clamping the opening and closing plate is installed in the second hydraulic groove, and a second hydraulic column for pushing the second clamping column to move is provided in the second hydraulic groove.

[0012] By adopting the above technical solution, the reciprocating movement of the second hydraulic column can push the hydraulic gas inside the second hydraulic groove, thereby pushing the second clamping column to move, and the second clamping column can complete the clamping of the opening and closing plate.

[0013] Optionally, a second spring for assisting the second hydraulic column in resetting is installed on the second hydraulic column, and a second pressing block penetrating the top of the workbench is arranged above the second hydraulic column, and the second pressing block is used to drive the second hydraulic column to move.

[0014] By adopting the above technical solution, when the bottom plate on the sliding base presses the second pressing block, the second hydraulic column can move away from the opening and closing plate, and the second spring is in a compressed state. When the bottom plate on the sliding base is separated from the second pressing block, the second spring rebounds, which can assist the second hydraulic column to approach the opening and closing plate.

[0015] Optionally, a second limiting component for limiting the opening and closing plates is provided on the frame and the workbench, and the second limiting component includes a hydraulic pipeline fixedly installed on the frame, a third hydraulic column is installed inside the hydraulic pipeline, a connecting rod for driving the third hydraulic column to move is installed on the pressing plate, one end of the hydraulic pipeline leads to the side wall of the workbench, and a third pressing block is installed on the workbench by opening a T-slot.

[0016] Optionally, a third clamping column clamped on the third pressing block is installed on the workbench, the third clamping column is vertically arranged to the third pressing block, and a third spring is installed on the third clamping column, and the third spring is used to drive the third clamping column to be clamped on the opening and closing plate.

[0017] By adopting the above technical solution, when the pressing plate moves downward to press the paper product, it can drive the third hydraulic column to move away from the closing plate, and then drive the third hydraulic column to release the restraint on the third clamping column. The third clamping column is clamped on the opening and closing plate under the release of the elastic force of the third spring, which can prevent the opening and closing plate from being opened due to external pressure during cutting.

[0018] Optionally, a pushing plate is slidably mounted on the workbench to push the paper product directly below the cutting blade, and the pushing plate is driven by an external driving member.

[0019] By adopting the above technical solution, the pushing plate can push the uncut paper product part close to the cutting blade and move it a certain distance, so as to facilitate the subsequent cutting of the paper product.

[0020] Optionally, transition plates are symmetrically mounted on the frame and located on both sides of the workbench, and the transition plates are used to stack the cut paper products in stacks.

[0021] By adopting the above technical solution, after the baffle board has finished arranging the paper products, the staff can temporarily place the neatly stacked paper products on the transition board to facilitate subsequent unified arrangement.

[0022] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects: 1. The baffle plate can be used to support a stack of tilted paper products after cutting to prevent them from collapsing. By adjusting the inclination angle of the baffle plate, the position of the stack of paper products tilted on the baffle plate can be corrected so that the paper products can be placed vertically and neatly to prevent them from scattering. The baffle plate can be used instead of manual operation to improve the safety of the working process.

[0023] 2. The opening and closing of the opening and closing plates are controlled by the limiter. When cutting the scraps of paper products, the limiter cancels the limit on the opening and closing plates, so that the opening and closing plates are opened to directly complete the collection of the scraps, which can improve work efficiency and prevent workers from getting close to the cutting blades to ensure safety during the work process. When cutting paper products of specific specifications, the opening and closing plates can be limited by the limiter to close the opening and closing plates to prevent the problem of cutting misalignment caused by the opening of the opening and closing plates, thereby ensuring work quality.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the embodiments of the present application. Figure 1-Figure 12 , the technical scheme of the embodiment of the present application is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Fig. 9 and Fig.12 This embodiment provides a paper product cutting device, including a frame 1, a sorting component 2, a waste collection component 3, a first limit component 4 and a second limit component 5. The frame 1 is provided with a workbench 11, a pressing plate 12 and a cutting blade. The workbench 11 is horizontally arranged on the frame 1, and a pressing plate 12 and a cutting blade located directly above the workbench 11 are installed on the frame 1. The pressing plate 12 and the cutting blade move back and forth respectively driven by an external driving member. The pressing plate 12 is used to press a stack of paper products on the workbench 11 to prevent the cutting blade from shifting when cutting the paper products. A sorting component 2 for supporting the cut paper products and a waste collection component 3 for collecting scraps are installed on the workbench 11. The waste collection component 3 includes an opening and closing plate 31. A first limiting component 4 is installed on the workbench 11, and a second limiting component 5 is installed on the frame 1 and the workbench 11. The first limiting component 4 and the second limiting component 5 are both used to limit the opening and closing plate 31. In different working states, the opening and closing plate 31 is limited or canceled to ensure that the scraps are collected in time or to prevent the cut products from falling.

[0028] Reference Figure 1A push plate 13 and a transition plate 14 are provided on the frame 1. The push plate 13 is slidably mounted on the workbench 11. The push plate 13 is driven by an externally connected driving member. The push plate 13 moves away from or close to the cutting blade under the drive of the driving member. The push plate 13 is used to drive the paper product raw material to move a certain distance toward the cutting blade. Transition plates 14 located on the frame 1 are symmetrically provided on both sides of the workbench 11. The cut paper products can be temporarily stored on the transition plates 14 to facilitate the subsequent unified transfer of the paper products.

[0029] Reference Figure 3 The finishing assembly 2 includes a sliding base 21, which is composed of a bottom plate 211, a top plate 212, a vertical plate 213 and an inclined plate 214. The sliding base 21 is slidably mounted on the workbench 11 and is located on the side where the cutting blade cuts the finished product. The bottom plate 211 on the sliding base 21 is slidably mounted on the workbench 11. The vertical plate 213 and the inclined plate 214 are connected between the bottom plate 211 and the top plate 212. The vertical plate 213 is located away from the cutting blade and parallel to the cutting blade, and the inclined plate 214 is located close to the cutting blade.

[0030] Reference Figure 2 , Figure 3 and Figure 4 The sorting assembly 2 also includes a baffle plate 22 , a pressing plate 23 , a first hydraulic block 24 , an extrusion groove 25 , a first hydraulic groove 26 and a first pushing block 27 . A rectangular groove is provided on the inclined plate 214, and a baffle plate 22 is installed on the rectangular groove. The baffle plate 22 is installed by hinges. When the baffle plate 22 is completely located inside the rectangular groove, the baffle plate 22 is used to support a stack of cut inclined paper products to prevent the paper products from collapsing. The pressing plate 23 is slidably arranged on the vertical plate 213 through an elastic member and is parallel to the bottom plate 211. When the pressing plate 23 is pressed, the pressing plate 23 can return to its original position under the connection of the elastic member. A first hydraulic block 24 is fixedly installed on the pressing plate 23. An extrusion groove 25 is provided on the bottom plate 211. The first hydraulic block 24 is located at the upper part of the extrusion groove 25. A first hydraulic groove 26 is provided on the workbench 11. The first hydraulic groove 26 is connected to the extrusion groove 25. A first pushing block 27 is arranged in the extrusion groove 25. The first pushing block 27 is used to push the baffle plate 22 to rotate so that the baffle plate 22 is perpendicular to the bottom plate 211, thereby arranging the inclined paper products.

[0031] When in use, first, the pushing plate 13 drives the stacked paper products to move a certain distance toward the cutting blade, so that the pressing plate 12 moves down to press the paper product raw materials, and the cutting blade moves down to cut the paper product raw materials into specific specifications. When the cutting blade cuts the stacked paper product raw materials, the cutting blade moves down continuously. Under the influence of cutting inertia, the paper products located on the upper part tend to tilt backwards. At this time, the sliding base 21 is pushed to make the baffle plate 22 on the inclined plate 214 support the inclined paper products to prevent the stacked paper products from falling and scattering. The baffle plate 22 can replace the operation of the staff to keep the staff's hands away from the cutting blade, thereby improving the safety during the work process.

[0032] After the cutting of paper products of specific specifications is completed, the pressing plate 23 is pressed downward to move the first hydraulic block 24 into the extrusion groove 25, and then the hydraulic gas inside the first hydraulic groove 26 pushes the first pushing block 27. The first pushing block 27 pushes the baffle plate 22 to rotate, so that the baffle plate 22 and the bottom plate 211 remain vertical. During the rotation of the baffle plate 22, the tilted stack of paper products is driven to be placed vertically. After the cutting blade and the pressing plate 12 move up and return to their original positions, the staff can move the sorted paper products to the transition plate 14.

[0033] Reference Figure 5 The waste collection assembly 3 includes an opening and closing plate 31 and a waste collection box 32. A through slot is provided on the workbench 11, and the through slot is located directly below the cutting blade. The opening and closing plate 31 is installed on the through slot through a torsion spring. Under the torsion force of the torsion spring, the opening and closing plate 31 is in a closed state, and a waste collection box 32 located on the workbench 11 is installed below the opening and closing plate 31.

[0034] When in use, after cutting the scraps on the paper product raw material, the pressing plate 12 and the cutting blade return to their original positions, and the staff opens the opening and closing plate 31 to allow the scraps to directly fall into the waste collection box 32 for unified collection.

[0035] Reference Figure 6 , Figure 7 Fig. 9 and Fig.10The first limiting assembly 4 includes a second hydraulic groove 41 , a second clamping column 42 , a second hydraulic column 43 , a second spring 44 and a second pressing block 45 . The second hydraulic groove 41 is opened on the workbench 11, and the second clamping column 42 and the second hydraulic column 43 are both installed in the second hydraulic groove 41, and the second clamping column 42 is clamped to the opening and closing plate 31. The opening and closing plate 31 is provided with a clamping groove matching the second clamping column 42, and a second hydraulic column 43 is provided in the second hydraulic groove 41 to push the second clamping column 42 to move, and a second spring 44 is installed on the second hydraulic column 43, and one end of the second spring 44 is fixedly connected to the inner wall of the second hydraulic groove 41 away from the closing plate 31, and a second pressing block 45 that passes through the top of the workbench 11 is arranged above the second hydraulic column 43, and the second hydraulic column 43 and the second pressing block 45 are both provided with inclined surfaces. When the second pressing block 45 moves downward, the second spring 44 is compressed, and the second hydraulic column 43 moves horizontally, and the hydraulic gas drives the second clamping column 42 to break away from the restraint on the opening and closing plate 31, and the sliding base 21 will press or release the second pressing block 45 during the movement.

[0036] During use, when the bottom plate 211 on the sliding base 21 presses on the second pressing block 45, the second spring 44 is compressed, and the hydraulic gas inside the second hydraulic groove 41 drives the second clamping column 42 to cancel the restraint on the opening and closing plate 31, making it convenient for the staff to open the opening and closing plate 31 so that the scraps fall into the waste collection box 32. When the sliding base 21 slides to make the baffle plate 22 arrange paper products of specific specifications, the bottom plate 211 is separated from the restraint on the second pressing block 45, and the elastic force of the second spring 44 is released, causing the second hydraulic column 43 to move horizontally, thereby causing the hydraulic gas inside the second hydraulic groove 41 to rush toward the second clamping column 42, and the second clamping column 42 enters the clamping groove of the opening and closing plate 31, completing the restraint on the opening and closing plate 31, ensuring that the cutting blade can prevent the opening and closing plate 31 from opening under the heavy pressure of the cutting blade when cutting paper products of specific specifications.

[0037] Reference Figure 8 , Fig.11 and Fig.12The second limiting assembly 5 includes a hydraulic pipeline 51, a third hydraulic column, a connecting rod, a third pressing block 52, a third clamping column 53 and a third spring 54. The hydraulic pipeline 51 is fixedly mounted on the frame 1, one end of the hydraulic pipeline 51 is located directly above the pressing plate 12, and the other end is connected to the side wall of the workbench 11. The third hydraulic column is installed inside the hydraulic pipeline 51, and a connecting rod for driving the third hydraulic column to move is installed on the pressing plate 12. A T-slot connected to the hydraulic pipeline 51 is provided on the workbench 11, and a third pressing block 52 and a third clamping column 53 are installed in the T-slot. The third pressing block 52 is clamped on the side wall of the third clamping column 53, and a third spring 54 is installed on the third clamping column 53. When the cutting blade is in the original position, the third pressing block 52 is clamped on the third clamping column 53, and the third spring 54 is in a compressed state, and the third clamping column 53 cancels the limiting of the opening and closing plate 31.

[0038] During use, when the pressing plate 12 moves downward to press the paper product, the connecting rod drives the third hydraulic column away from the closing plate 31, and then the hydraulic gas inside the hydraulic pipe 51 drives the third pressing block 52 to break away from the restraint on the third clamping column 53. Under the recovery of the elastic force of the third spring 54, the third spring 54 drives the third clamping column 53 to be clamped inside the opening and closing plate 31. Similarly, when the pressing plate 12 returns to its original position, the connecting rod drives the third hydraulic column close to the opening and closing plate 31, and the hydraulic gas inside the hydraulic pipe 51 drives the third pressing block 52 to restrain the third clamping column 53. The third spring 54 is compressed, and the third clamping column 53 is freed from the restraint on the opening and closing plate 31.

[0039] The implementation principle of a paper product cutting device in the embodiment of the present application is as follows: When using the device, the scraps of the raw materials of paper products are first cut. When the pressing plate 12 presses the paper products, the second limiting component 5, under the hydraulic gas and a series of clamping limits, clamps and limits the opening and closing plate 31 to prevent the pressing force of the cutting blade from cutting downward and opening the opening and closing plate 31. When cutting the scraps, there is no need to slide the base 21 to arrange the paper products. The bottom plate 211 on the sliding base 21 presses on the second pressing block 45 of the first limiting component 4. Under the hydraulic gas and a series of clamping limits, the first limiting component 4 is in a state of canceling the restraint on the opening and closing plate 31. When the pressing plate 12 returns to its original position, the second limiting component 5 cancels the restraint on the opening and closing plate 31, and the opening and closing plate 31 is opened to collect the scraps. Afterwards, when cutting paper products of specific specifications, the sliding base 21 releases the restraint on the second pressing block 45. At this time, the first limiting assembly 4 clamps and limits the opening and closing plate 31, and the baffle plate 22 on the inclined plate 214 supports the stack of inclined paper products that have been cut. Then, the pressing plate 23 is pressed, and the first hydraulic block 24 pushes the hydraulic gas inside the first hydraulic groove 26. The hydraulic gas acts on the first pushing block 27 to make the baffle plate 22 perpendicular to the bottom plate 211, so that the inclined stack of paper products is straightened. Finally, the staff moves the stack of paper products to a specific position.

[0040] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0041] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
