Description

Technical Field

[0001] This utility model relates to the technical field of paper bag manufacturing, and in particular to an integrated die-cutting roller holder for paper bags. Background Technology

[0002] In the paper bag manufacturing industry, when a paper bag is unopened, its two main layers of paper are tightly packed together due to the bonding process or natural stacking effect during manufacturing. This structural feature often requires users to spend extra time and skill to separate the two layers and open the bag smoothly. The handle was designed to solve this problem. Essentially, it is a notch created in one of the two layers of paper. This notch allows for direct application of force to the separation interface between the two layers, providing users with a convenient point of leverage and significantly reducing the difficulty of separating the two layers, thus enabling the bag to be opened quickly. Currently, the industry commonly uses roller die-cutting technology for the die-cutting of paper bag handles. The core component of this process is a die-cutting roller equipped with a die cutter. Its working principle is that the rotation of the die-cutting roller drives the die cutter to move synchronously. When the continuously fed paper bag strips (usually strips of pre-formed paper rolls) pass uniformly over the die-cutting roller, the die cutter on the roller performs a top cut on the paper bag strip with each rotation, thus forming the pre-set handle cut on the paper bag strip. In subsequent processes, the paper bag strips cut at the handle are further divided into individual paper bags, ultimately achieving the production goal of ensuring that each paper bag has a complete handle, guaranteeing convenient use for users.

[0003] However, existing die-cutting roller cutter holders have the following shortcomings in actual use: In actual production, paper bags of different specifications and uses (such as food packaging paper bags, shopping paper bags, gift packaging paper bags, etc.) often require different shapes (such as round, semi-circular, rectangular, irregular, etc.) or different sizes of handle positions due to differences in size, load-bearing requirements, and appearance design. Existing die-cutting roller cutter holders can only accommodate one die. When production needs are switched from one handle position specification to another, operators must disassemble the cutter holder on the die-cutting roller: first, loosen the fixing connection between the cutter holder and the die-cutting roller using special tools, and remove the original die from the cutter holder; then, install the die adapted to the new handle position into the cutter holder, and retighten the fixing connection; afterwards, the installation position of the die (ensuring alignment with the positioning reference of the paper bag strip) and verticality (to avoid skewed cuts during punching) and other parameters need to be repeatedly adjusted until the die-cutting accuracy requirements are met before the production line can be restarted to resume operation. Such frequent die-cutting and equipment debugging operations severely impact production efficiency. Moreover, the repeated debugging process not only increases the complexity of equipment operation but also easily leads to problems such as handle position cut deviation, burrs, and incomplete cuts due to human error, thereby increasing the product defect rate. In view of this, the integrated die holder for paper bag die-cutting rollers proposed in this application is proposed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an integrated die holder for paper bag die-cutting rollers that can quickly replace various die cutters and reduce repeated equipment adjustments, thereby improving production efficiency and product quality.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] An integrated die holder for paper bag die-cutting rollers includes:

[0007] Die-cutting rollers; and

[0008] A tool collecting assembly includes a tool holder, a bushing, an elastic element, and several tool clamping elements. The tool holder is coaxially mounted on the die-cutting roller. Each tool clamping element is rotatably mounted on the tool holder and is equidistantly distributed along the circumference of the tool holder. The bushing is coaxially rotatably mounted on the die-cutting roller, with one end of the bushing covering the tool holder and each tool clamping element. The bushing has several slots corresponding to each tool clamping element. The two ends of the elastic element abut against the tool holder and the bushing, respectively. The elastic element pushes the bushing to rotate relative to the die-cutting roller, causing one of the tool clamping elements to engage in the slot in a vertical position.

[0009] Optionally, the slot is provided with a locking platform, which is located at the opening of the slot, and the locking platform and an inner sidewall of the slot jointly engage the clamping tool.

[0010] Optionally, the bushing has a circular groove, and each of the slots is connected to the inner wall of the circular groove and the outer wall of the bushing.

[0011] Optionally, the bushing has an annular groove, a top block is provided in the annular groove, a push block is provided on the tool holder, the elastic element is located in the annular groove, and the two ends of the elastic element abut against the top block and the push block respectively.

[0012] Optionally, the bushing is provided with a guide ring, one end of the guide ring is disposed on the top block, the other end of the guide ring passes through the push block, and the elastic element is sleeved on the guide ring.

[0013] Optionally, the tool holder has a plurality of grooves, each groove being equidistantly distributed along the circumference of the tool holder, and each tool clamping member being rotatably disposed in each groove in a corresponding manner.

[0014] Optionally, the cutter holder includes a cutter disc and a sandwich block. The cutter disc is coaxially disposed on the die-cutting roller, the sandwich block is coaxially disposed on the cutter disc, each of the grooves is formed on the cutter disc, and the push block is disposed on the sandwich block.

[0015] Optionally, a U-shaped groove is formed on the inner sidewall of the groove, and a protrusion is provided on the clamping tool, the protrusion being rotatably engaged with the U-shaped groove.

[0016] Optionally, the clamping member includes a base block and a locking plate, the protrusion is disposed on the base block, and the locking plate is used to clamp the die cutter together with the base block.

[0017] Optionally, the bottom surface of the base block has an arc-shaped structure.

[0018] Compared with the prior art, the present invention has at least the following advantages:

[0019] This utility model discloses an integrated die-cutting roller holder for paper bags. Each die-clamping component is rotatably mounted on the holder, and an elastic element is provided between the bushing and the holder. The bushing has slots corresponding to each die-clamping component. When changing the die, there is no need to disassemble the connection structure between the die-clamping components and the holder. The worker only needs to manually rotate the bushing to disengage the current slot from the corresponding die-clamping component, allowing the vertical die-clamping component to rotate to a parallel position. Then, the parallel die-clamping component with the target die-shaped die is rotated into the empty slot, making it vertical. After releasing the bushing, the elastic element pushes the bushing back to its original position, causing the slot to tightly engage with the new die-clamping component, completing the die replacement. The entire process does not require disassembling the fixing structure of the die and the die-clamping components, nor does it require readjusting the connection position between the die-clamping components and the holder, significantly shortening the die replacement and subsequent equipment debugging time, effectively improving production efficiency.

[0032] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0033] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0036] like Figure 1 Only Figure 9 As shown, in one embodiment, an integrated paper bag die-cutting roller knife holder 1 includes a die-cutting roller 10 and a knife-collecting assembly. The knife-collecting assembly includes a knife holder 20, a bushing 21, an elastic element 22, and a plurality of knife-clamping elements 23. The knife holder 20 is coaxially disposed on the die-cutting roller 10. Each knife-clamping element 23 is rotatably disposed on the knife holder 20, and each knife-clamping element 23 is equidistantly distributed along the circumference of the knife holder 20. The bushing 21 is coaxially rotatably disposed on the die-cutting roller 10, and one end of the bushing 21 covers the knife holder 20 and each knife-clamping element 23. The bushing 21 has a plurality of slots 210 corresponding to each knife-clamping element 23. The two ends of the elastic element 22 abut against the knife holder 20 and the bushing 21, respectively. The elastic element 22 pushes the bushing 21 to rotate relative to the die-cutting roller 10, so that one of the knife-clamping elements 23 is engaged in the slot 210 in a vertical state.

[0037] It should be noted that the blade holder 20 is coaxially mounted on the die-cutting roller 10. For example, a raised circular tube structure is integrally formed on one side of the blade holder 20 and screwed onto the circular tube structure, so that the screw can press against the die-cutting roller 10 when tightened. In this way, the blade holder 20 can be synchronously rotated when the die-cutting roller 10 rotates, and the position of the blade holder 20 relative to the die-cutting roller 10 is also adjustable. Furthermore, each clamping blade 23 is rotatably mounted on the blade holder 20, and the axis of each clamping blade 23 can be perpendicular or parallel to the axis of the die-cutting roller 10. Moreover, each clamping blade 23 is equidistantly distributed along the circumference of the blade holder 20. Furthermore, the bushing 21 is rotatably mounted coaxially on the die-cutting roller 10. When the axes of each clamping blade 23 are parallel to the axis of the die-cutting roller 10, one end of the bushing 21 can completely cover the blade holder 20 and part of the structure of each clamping blade 23. This ensures that when the die-cutting roller 10 drives the blade holder 20 to rotate, each clamping blade 23 rotates around the die-cutting roller 10 in a parallel state. Furthermore, the bushing 21 has several slots 210, which are equidistantly distributed along the circumference of the bushing 21. The number of slots 210 corresponds to the number of clamping blades 23, ensuring that each clamping blade 23 is positioned within its respective slot when perpendicular to the blade holder 20. Furthermore, for example, the elastic element 22 is a spring structure, and its two ends abut against the knife holder 20 and the bushing 21 respectively. The knife holder 20 is fixedly connected to the die-cutting roller 10 by screws, so that the elastic element 22 can push the bushing 21 to rotate around the axis of the die-cutting roller 10, so that the bushing 21 drives the inner side wall of each slot 210 to engage with each clamping member 23 respectively. Furthermore, the clamping member 23 is used to clamp the die cutter 26. When any clamping member 23 is engaged in the slot 210 in a vertical state, the die-cutting roller 10 can drive the clamping member 23 to perform a top-cutting operation on the paper bag strip once for each rotation. Furthermore, when it is necessary to produce handles of other shapes, the worker rotates the bushing 21 to disengage the slot 210 from the clamping member 23, so that the clamping member 23, which is in a vertical state, can rotate relative to the tool holder 20 to a parallel state. At the same time, the other shaped die cutter 26, which is in a parallel state, is rotated into another slot 210 to a vertical state. Then the bushing 21 is released, and under the push of the elastic member 22, the bushing 21 drives the slot 210 to maintain engagement with the clamping member 23, thereby keeping the clamping member 23 in a vertical state.This allows workers to quickly change the die cutter 26 of different shapes according to actual production needs. Moreover, each clamping part 23 is rotatably mounted on the cutter holder 20. When changing the die cutter, only the clamping part 23 that needs to be used is changed from a parallel state to a vertical state. Therefore, the connection position between each clamping part 23 and the cutter holder 20 is always fixed, avoiding the steps of disassembling and assembling the die cutter 26. This reduces the impact on the cutting accuracy of the die cutter 26. In this way, the time for frequently changing the die cutter 26 and the time for debugging the equipment after the change are reduced, thereby improving production efficiency and product quality.

[0038] like Figures 1 to 5 , Figure 7 , Figure 9 As shown, in one embodiment, the slot 210 is provided with a locking platform 2100, which is located at the opening of the slot 210. The locking platform 2100 and an inner sidewall of the slot 210 jointly engage the clamping tool 23.

[0039] It should be noted that the slot 210 is provided with a mounting plate 2100, and the mounting plate 2100 is located at the opening of the slot 210, so that the width of the opening of the slot 210 is less than the width of the inner bottom wall of the slot 210, forming an L-shaped structure; further, the width of the opening of the slot 210 is greater than the width of the clamping member 23, so that the clamping member 23 rotates relative to the tool holder 20 into the slot 210 and abuts against the inner bottom wall of the slot 210; further, when the clamping member 23 is vertically located in the slot 210, under the elastic force of the elastic member 22, the bushing 21 drives the inner side wall of the slot 210 near the mounting plate 2100 to abut against the clamping member 23, and simultaneously drives the mounting plate 2100 to abut against the side adjacent to the clamping member 23, so that the clamping member 23 cannot rotate relative to the tool holder 20, thereby keeping the clamping member 23 in a vertical state. Furthermore, when the bushing 21 covers the tool holder 20, each slot 210 communicates with the outer wall of the tool holder 20, and the retaining platform 2100 on each slot 210 extends relative to the side of the tool holder 20 away from the bushing 21. Thus, when the elastic element 22 drives the bushing 21 to abut against a clamping member 23, the other slots 210 simultaneously drive their retaining platforms 2100 to abut against the other parallel clamping members 23, preventing the parallel clamping members 23 from rotating relative to the tool holder 20. This prevents the parallel clamping members 23 from tailing during the rotation of the die-cutting roller 10.

[0040] like Figures 7 to 9 As shown, in one embodiment, a circular groove 211 is provided on the bushing 21, and each slot 210 is connected to the inner side wall of the circular groove 211 and the outer side wall of the bushing 21.

[0041] It should be noted that a circular groove 211 is formed on the end face of the bushing 21 near the tool holder 20. The depth of the circular groove 211 is the same as the thickness of the tool holder 20, so that the bushing 21 can completely cover the tool holder 20. Furthermore, the inner diameter of the circular groove 211 is adapted to the outer diameter of the tool holder 20, and the two sides of each slot 210 are respectively connected to the inner sidewall of the circular groove 211 and the outer sidewall of the bushing 21. In this way, when the tool holder 23 is in a vertical state, it can extend relative to the outer sidewall of the bushing 21.

[0042] like Figures 7 to 9 As shown, in one embodiment, the bushing 21 has an annular groove 212, a top block 2120 is provided in the annular groove 212, a push block 2010 is provided on the tool holder 20, and an elastic member 22 is located in the annular groove 212, with both ends of the elastic member 22 abutting against the top block 2120 and the push block 2010 respectively.

[0043] It should be noted that the annular groove 212 is formed on the inner bottom wall of the circular groove 211, and a top block 2120 is provided in the annular groove 212. The top block 2120 is located in the annular groove 212 with a structure that cuts through the annular groove 212. A push block 2010 is provided on the cutter holder 20. The push block 2010 is located on the end face of the cutter holder 20 near the bushing 21. When the bushing 21 covers the cutter holder 20, the push block 2010 fits into the annular groove 212. When the bushing 21 rotates relative to the die-cutting roller 10, the push block 2010 can slide along the opening direction of the annular groove 212. Furthermore, the elastic member 22 is located in the annular groove 212 in a ring shape, and the elastic member 22 The two ends of the blade holder 20 abut against the top block 2120 and the push block 2010, respectively. Since the blade holder 20 is fixedly mounted on the die-cutting roller 10, when the die-cutting roller 10 is stationary, the push block 2010 mounted on the blade holder 20 will also be stationary. Thus, when the worker manually rotates the bushing 21, the bushing 21 drives the top block 2120 to rotate and press the elastic element 22 to replace the clamping blade 23. When the worker releases his hand, since the push block 2010 is stationary, the elastic element 22 will push the top block 2120 to rotate the bushing 21, so that the bushing 21 drives the slot 210 to engage with the clamping blade 23. In this way, the worker can quickly replace the clamping blade 23, thereby improving production efficiency.

[0044] like Figure 4 , Figures 7 to 8 As shown, in one embodiment, a guide ring 213 is provided on the bushing 21. One end of the guide ring 213 is provided on the top block 2120, and the other end of the guide ring 213 is passed through the push block 2010. The elastic element 22 is sleeved on the guide ring 213.

[0045] It should be noted that there are two top blocks 2120, both located within the annular groove 212 in a manner that cuts off the annular groove 212, and the two top blocks 2120 are arranged opposite each other, so that the two top blocks 2120 divide the annular groove 212 into a first annular groove and a second annular groove; there are also two push blocks 2010, both located on the side of the tool holder 20 near the bushing 21, and the two push blocks 2010 are respectively located in the first annular groove and the second annular groove, and the two push blocks 2010 can slide along the opening direction of the first annular groove and the second annular groove, respectively; furthermore, a guide ring 213 is disposed on the two top blocks 2120, and since the two top blocks 2120 are arranged opposite each other, the two top blocks 2120 can slide along the opening direction of the first annular groove and the second annular groove, respectively; The guide ring 20 is fixedly connected to the two opposite ends of the guide ring 213. Furthermore, the diameter of the guide ring 213 is smaller than the groove width of the annular groove 212 and smaller than the minimum diameter of the elastic element 22, so that the guide ring 213 is in a suspended state except at the position where it is connected to the two top blocks 2120, and the guide ring 213 is located in the first annular groove and the second annular groove respectively. Furthermore, the two push blocks 2010 are located in the first annular groove and the second annular groove respectively, and the guide ring 213 located in the first annular groove and the second annular groove respectively passes through the two push blocks 2010 to prevent the bushing 21 from separating from the tool holder 20, and at the same time, the two push blocks 2010 can slide along the guide ring 213 in the first annular groove and the second annular groove respectively. Furthermore, two elastic elements 22 are provided, both of which are sleeved on the guide ring 213; one elastic element 22 is located in the first annular groove, with its two ends abutting against a top block 2120 and a push block 2010 respectively, while the other elastic element 22 is located in the second annular groove, with its two ends abutting against another top block 2120 and another push block 2010 respectively. In this way, when the bushing 21 rotates relative to the die-cutting roller 10, both top blocks 2120 rotate circumferentially around the axis of the die-cutting roller 10, so as to simultaneously squeeze the two elastic elements 22.

[0046] like Figures 1 to 4 , Figure 6 As shown, in one embodiment, the tool holder 20 has a plurality of grooves 2000, each groove 2000 is equidistantly distributed along the circumference of the tool holder 20, and each tool clamping member 23 is rotatably disposed in each groove 2000 in a corresponding manner.

[0047] It should be noted that each groove 2000 is opened on the end of the cutter holder 20 away from the bushing 21, and one end of each clamping member 23 is rotatably disposed in each groove 2000; and the two adjacent ends of each groove 2000 are respectively connected to the end face of the cutter holder 20 away from the bushing 21 and the outer wall, so that each clamping member 23 can only be parallel to the axis of the die-cutting roller 10 in the direction away from the bushing 21, or radially perpendicular to the axis of the die-cutting roller 10.

[0048] like Figure 4, Figure 6 As shown, in one embodiment, the cutter holder 20 includes a cutter disc 200 and a sandwich block 201. The cutter disc 200 is coaxially disposed on the die-cutting roller 10, and the sandwich block 201 is coaxially disposed on the cutter disc 200. Each groove 2000 is formed on the cutter disc 200, and a pusher block 2010 is disposed on the sandwich block 201.

[0049] It should be noted that, for ease of initial installation and subsequent maintenance, the cutter holder 20 includes a cutter disc 200 and a sandwich block 201. The cutter disc 200 is coaxially mounted on the die-cutting roller 10, and the sandwich block 201 is coaxially mounted on the cutter disc 200. Grooves 2000 are equidistantly distributed circumferentially on the cutter disc 200. Two push blocks 2010 are symmetrically arranged circumferentially on the end face of the sandwich block 201 away from the cutter disc 200, with the axis of the die-cutting roller 10 as the center. In another embodiment, the cutter disc 200 and the sandwich block 201 are integrally formed.

[0050] like Figure 6 As shown, in one embodiment, a U-shaped groove 2001 is provided on the inner sidewall of the groove 2000, and a protrusion 2300 is provided on the clamping member 23, which is rotatably engaged with the U-shaped groove 2001.

[0051] It should be noted that U-shaped grooves 2001 are provided on both inner sidewalls of the groove 2000 facing each other, with the opening of the U-shaped groove 2001 facing the side of the interlayer block 201. When the worker installs the clamping tool 23 in the early stage, the protrusion 2300 is slid into the opening of the U-shaped groove 2001, and then the interlayer block 201 is installed. When the interlayer block 201 is placed on the cutter head 200, it blocks the opening of the U-shaped groove 2001, thus preventing the clamping tool 23 from falling off the cutter head 200.

[0052] like Figures 1 to 6 As shown, in one embodiment, the clamping member 23 includes a base block 230 and a locking plate 24. A protrusion 2300 is disposed on the base block 230, and the locking plate 24 is used to clamp the die cutter 26 together with the base block 230.

[0053] It should be noted that a protruding post 2300 is provided on each of the two opposing ends of the bottom block 230, and the height of the protruding post 2300 is consistent with the depth of the U-shaped groove 2001. The protruding posts 2300 on both ends of the bottom block 230 are respectively rotatably engaged with the U-shaped groove 2001 facing the groove 2000, so that the bottom block 230 can drive the die cutter 26 to rotate relative to the die disc 200. Furthermore, a die-holding groove is provided on the bottom block 230, and one end of the die cutter 26 is engaged in the die-holding groove. The locking plate 24 is screwed through the die cutter 26 and screwed to the bottom block 230, so that the locking plate 24 and the bottom block 230 together clamp the die cutter 26.

[0054] like Figures 1 to 3 , Figure 6 As shown, in one embodiment, the bottom surface of the bottom block 230 has an arc-shaped structure.

[0055] It should be noted that the side of the bottom block 230 away from the die cutter 26 has a semi-circular arc structure. When the bottom block 230 drives the die cutter 26 to a vertical state, the arc structure of the bottom block 230 is tangent to the inner bottom wall of the groove 2000. When the bottom block 230 drives the die cutter 26 to a parallel state, the arc structure of the bottom block 230 is tangent to the end face of the interlayer block 201 near the cutter head 200. In this way, the protrusion 2300 and the U-shaped groove 2001 rotate coaxially, thereby keeping the position of each clamping member 23 rotatably connected to the cutter head 200 fixed.

[0056] like Figure 5 As shown, in one embodiment, the blade assembly further includes a limiting ring 25.

[0057] It should be noted that the limiting ring 25 is coaxially disposed on the die-cutting roller 10. For example, the limiting ring 25 is vertically screwed onto the die-cutting roller 10 by screws, so that when the screws are tightened, they press against the die-cutting roller 10, thereby causing the limiting ring 25 to rotate synchronously with the die-cutting roller 10. Furthermore, the limiting ring 25 is located on the side of the bushing 21 away from the cutter holder 20, and the limiting ring 25 is in close contact with the bushing 21 to restrict the bushing 21 from sliding away from the cutter holder 20.
