Description

Technical Field

[0001] This application relates to the field of paper container production technology, and in particular to a paper bending and feeding device and a paper forming tool. Background Technology

[0002] With the development of paper container production technology, devices for feeding paper sheets before paper container forming have emerged. These paper sheet feeding devices can automatically transfer paper sheets to the paper container forming device, which improves the automation level of the paper container production process to a certain extent.

[0003] Before entering the forming process, the paper needs to be pre-bent to eliminate the stress rebound of the paper in its natural state and avoid inconsistent bending direction and curling edges, which would affect the subsequent production process. In the existing technology, the paper is usually picked up manually and physically bent by experience before being placed at the feeding station. Manual operation is not only costly, but also has a low degree of automation and is prone to errors.

[0004] In existing technologies, paper can be automatically bent by adding a bending mechanism. However, the gripping device, conveying device and bending device in the existing bending mechanism need to be set up independently and cooperate with each other to achieve automated bending. In order to avoid interference between the paper container and the various components during transportation, the independently set components occupy a lot of space and are difficult to set up and cooperate with each other, which increases space costs, easily leads to resource waste and reduced efficiency. Summary of the Invention

[0005] Therefore, it is necessary to provide a paper bending feeding device and paper forming fixture to address the problems of existing feeding devices that can automate paper bending having complex structures and large space requirements, leading to increased costs and reduced efficiency.

[0006] A paper bending and feeding device is disposed between a paper conveying device and a paper forming device for automatically bending and conveying paper sheets. The device includes a frame, a clamping mechanism, a paper conveying mechanism, and a bending mechanism. The frame includes a base plate and a top plate detachably disposed on the base plate, the base plate and the top plate forming an accommodating space. The clamping mechanism is slidably disposed on the top plate and located within the accommodating space for clamping paper sheets. The paper conveying mechanism is slidably disposed on the base plate and located within the accommodating space for placing and transporting paper sheets. The folding mechanism includes a bending component and a fixing member fixed to the base plate. The bending component includes a connector and a pair of bending members that are movably mounted on the connector. The connector is slidably mounted on the fixing member. Along the height direction of the frame, the pair of bending members are spaced apart and can be moved closer or further apart from each other. The connector is located between the gripping mechanism and the paper conveying mechanism. When the gripping mechanism grips the paper and places it on the paper conveying mechanism, the connector slides to the position of the paper so that the two bending members can be brought closer together to squeeze and bend the paper.

[0007] With this configuration, the clamping mechanism, paper conveying mechanism, and bending mechanism are all centrally located within the frame's storage space, allowing paper sheets to be transported and bent synchronously at the same workstation. A pair of bending members are vertically mounted on the connecting member of the bending mechanism, enabling them to approach each other and compress the paper sheet, thus eliminating stress rebound in the paper's natural state. The connecting member of the bending assembly is slidably mounted on the fixed member, positioned between the clamping mechanism and the paper conveying mechanism. This allows the bending mechanism to be positioned along the movement path of the clamping mechanism without obstructing its paper transport. When the paper sheet is placed on the paper conveying mechanism, the connecting member can slide directly to the paper's location and bend it using the bending members, shortening the bending steps and reducing the additional space occupied by the bending mechanism. This improves paper sheet production efficiency and reduces costs.

[0008] In one embodiment, the fixing member is provided with a guide rail in a direction perpendicular to the sliding direction of the paper conveying mechanism, and the connecting member of the bending assembly is provided with a groove that matches the guide rail. The groove can be embedded in the guide rail and can slide along the guide rail.

[0009] With this configuration, the fixing component is equipped with a guide rail along the direction perpendicular to the paper conveying mechanism, which can minimize the space occupied by the bending mechanism and shorten the sliding distance of the connecting component, thereby reducing space costs and improving production efficiency. The connecting component can be directly slid by the guide rail and the slide groove, which is convenient and quick, and facilitates the automated operation of the connecting component by the drive device.

[0010] In one embodiment, the bending assembly further includes a telescopic cylinder, which includes a telescopic cylinder body and movable parts telescopically disposed at both ends of the telescopic cylinder body. The telescopic cylinder body is fixed to the connecting part, and the two bending parts are respectively fixedly connected to the movable parts.

[0011] With this configuration, the two bending components are fixedly connected to the movable component, which can prevent the paper from deforming or being damaged due to uneven force. The bending components are raised and lowered along the height of the frame by the telescopic cylinder body and the movable component. This avoids the need to arrange the bending components on the frame in other ways, which would increase the overall space of the bending mechanism and the number of paper bending steps. In addition, the cylinder drive method is responsive and stable, which facilitates automated control and improves bending efficiency. At the same time, the overall structure is integrated into the connecting component, saving space.

[0012] In one embodiment, each bending member of the bending assembly includes a limiting member and a limiting protrusion protruding from the limiting member. The limiting member is fixedly connected to the movable member. The limiting protrusion and the limiting member form a limiting groove for limiting the paper. When the connecting member slides to the point where the paper is located in the limiting groove, the telescopic cylinder body is compressed to drive the two bending members to move closer to each other and squeeze the paper to bend.

[0013] With this design, the limiting groove can precisely engage with the edge of the paper, ensuring that the paper remains in a fixed position during bending, preventing the paper from sliding or shifting, and improving the accuracy and consistency of bending. When the connector moves into place, the telescopic cylinder body can be quickly compressed, so that the two bending parts work together to squeeze the paper through the limiting groove, achieving efficient bending.

[0014] In one embodiment, the paper conveying mechanism includes a support member slidably disposed on a base plate and a clamping assembly fixed at both ends of the support member. A positioning member is fixed in the middle of the support member for positioning and placing paper pieces. The clamping assembly includes a fixing part fixed at the end of the support member and a clamping member telescopically connected to the fixing part. The clamping member is used to clamp and fix the paper pieces.

[0015] This design, with its sliding support, allows the paper sheet to be directly transported to the bending station after bending, enabling a compact layout between the paper conveying mechanism and the bending mechanism, thus reducing the overall space of the paper bending and feeding device. The positioning component ensures that the clamping mechanism accurately places the paper sheet. Through the telescopic cooperation of the fixing part and the clamping component, the clamping assembly can extend to approach and clamp the paper sheet after it is placed on the positioning component, facilitating the bending mechanism to bend the paper sheet. In addition, the telescopic cooperation of the fixing part and the clamping component allows the clamping assembly to be arranged on the movement path of the clamping mechanism, enhancing the continuity of the paper sheet transportation and bending process, facilitating automated operation and improving the production efficiency of the paper sheet.

[0016] In one embodiment, a limiting component fixed to the support is further included. The limiting component includes a lifting cylinder fixed to the support, a second telescopic cylinder movably disposed on the lifting cylinder, and a limiting shaft telescopically connected to the second telescopic cylinder. The limiting shaft is used to abut against the side of the paper sheet.

[0017] With this configuration, the limiting component, through the cooperation of the lifting cylinder and the second telescopic cylinder, can realize the vertical lifting and horizontal extension of the limiting shaft. This allows the limiting shaft to be positioned on the straight transport path of the paper sheet, preventing it from obstructing the straight transport of the paper sheet. When the paper sheet is transported to the positioning component, it can rise vertically and extend horizontally to abut against the paper sheet, achieving a compact layout of the paper conveying mechanism and the bending mechanism, reducing the overall accommodating space. The abutment of the limiting shaft against the paper sheet ensures that the paper sheet undergoes directional bending, preventing the paper sheet from bending in other directions and affecting subsequent paper sheet forming.

[0018] In one embodiment, the axial direction of the limiting shaft is perpendicular to the extension and retraction direction of the bent member.

[0019] With this configuration, the axial direction of the limiting shaft is perpendicular to the extension and retraction direction of the bending component, ensuring that the lateral limiting effect of the limiting shaft does not interfere with the bending and squeezing action of the bending component. This ensures the bending quality of the paper sheet, improves space utilization, facilitates the sequential execution of the limiting and bending steps of the paper sheet, and increases the production efficiency of the paper sheet.

[0020] In one embodiment, the base plate is provided with a second guide rail, and the end of the support member is provided with a second guide groove that matches the second guide rail. The second guide groove can be embedded in the second guide rail and can slide along the second guide rail.

[0021] This configuration, with the cooperation of the second guide rail and the second guide groove, allows the support to slide smoothly and steadily along the base plate, ensuring the straight-line accuracy and smoothness of the paper conveying mechanism in transporting paper sheets. It also facilitates disassembly and positioning, thereby improving the production efficiency of paper sheets.

[0022] This application also provides a paper sheet forming fixture, including a paper sheet conveying device for supplying paper sheets, a paper sheet forming device, and a paper sheet bending feeding device as described in any of the above embodiments, wherein the paper sheet bending feeding device is disposed between the paper sheet conveying device and the paper sheet forming device.

[0023] With this setup, the paper bending and feeding device, in conjunction with the paper conveying device and the paper forming device, enables rapid and high-quality paper production. The paper bending and feeding device can convey and bend paper at the same station, which reduces the production space occupied by the additional bending mechanism, thereby reducing production costs, while ensuring the production speed of paper, facilitating automated operation, and improving the production efficiency of paper.

[0024] In one embodiment, the paper forming fixture further includes a paper separating mechanism, which includes a support fixed on the paper conveying device and two rotating shafts rotatably disposed on the support. Each rotating shaft is provided with two paper separating blocks spaced apart in the circumferential direction. The width between the two rotating shafts is greater than or equal to the width of the paper, and the two paper separating blocks on each rotating shaft abut against the paper at intervals as the rotating shaft rotates.

[0025] With this configuration, the width between the two rotating shafts is greater than or equal to the width of the paper, ensuring that the paper separating mechanism completely separates the paper on the conveying device. The two paper separating blocks on the rotating shafts abut against the paper at intervals as the rotating shafts rotate, so that the paper on the conveying device can be separated into paper pieces of a preset thickness as the rotating shafts rotate. This facilitates the subsequent gripping mechanism to grip and transport the paper pieces, preventing the gripping mechanism from being unable to completely grip and transport the paper pieces due to too many separated paper pieces, and also preventing the gripping mechanism from gripping too many paper pieces, which would affect the bending effect of the paper pieces.

[0039] Considering the problems of low efficiency and error-prone manual bending of paper sheets to eliminate stress rebound in the natural state, and the high cost and complex structure of automated bending equipment, this application provides a paper sheet bending feeding device. This device is located between the paper sheet conveying device and the paper sheet forming device, enabling the paper sheets to be transported and bent synchronously at the same station. This ensures the bending effect while reducing the overall space occupied by the device, and facilitates automated control, thereby improving paper sheet production efficiency and reducing costs.

[0040] Specifically, see Figure 1 and Figure 2 As shown, this application provides a paper bending and feeding device. The paper bending and feeding device 1 is disposed between the paper conveying device 2 and the paper forming device 3, and is used for automatically bending and conveying paper sheets 100. It includes a frame 10, a clamping mechanism 20, a paper conveying mechanism 30 and a bending mechanism 40. The frame 10 includes a base plate 11 and a top plate 12 detachably disposed on the base plate 11. The base plate 11 and the top plate 12 form an accommodating space 200. The clamping mechanism 20 is slidably disposed on the top plate 12 and located in the accommodating space 200, and is used to clamp the paper sheet 100. The paper conveying mechanism 30 is slidably disposed on the base plate 11 and located in the accommodating space 200, and is used to place and transport the paper sheet 100. The bending mechanism 40 includes a bending component 41 and a fixing member 42 fixed to the base plate 11. The bending component 41 includes a connector 411 and a pair of bending members 412 that are movably mounted on the connector 411. The connector 411 is slidably mounted on the fixing member 42. Along the height direction of the frame 10, the pair of bending members 412 are spaced apart and can be moved closer or further apart from each other. The connector 411 is located between the clamping mechanism 20 and the paper conveying mechanism 30. When the clamping mechanism 20 clamps the paper 100 and places it on the paper conveying mechanism 30, the connector 411 slides to the position of the paper 100 so that the two bending members 412 are relatively close to each other and squeeze the paper 100 to bend it.

[0041] More specifically, see Figures 2 to 4As shown, the clamping mechanism 20, the paper conveying mechanism 30, and the bending mechanism 40 are all centrally arranged within the accommodating space 200 of the frame 10, allowing the paper sheet 100 to be transported and bent synchronously at the same workstation. A pair of bending members 412 are movably mounted on the connecting member 411 of the bending mechanism 40, allowing the two bending members 412 to approach each other and compress the paper sheet 100, thereby eliminating the stress rebound of the paper sheet 100 in its natural state. The connecting member 411 of the bending assembly 41 is slidably mounted on the fixing member 42, and the connecting member 411 is located between the clamping mechanism 20 and the paper conveying mechanism 30, allowing the bending mechanism to... The folding mechanism 40 can be set on the movement path of the gripping mechanism 20. When the gripping mechanism 20 transports the paper sheet 100, the connecting member 411 can slide away from the gripping mechanism 20 to avoid obstructing the gripping mechanism 20 from transporting the paper sheet 100. When the paper sheet 100 is placed on the paper conveying mechanism 30, the connecting member 411 can slide directly to the position of the paper sheet 100 and bend the paper sheet 100 through the bending member 412, which shortens the bending steps of the paper sheet 100 and reduces the space required by the bending mechanism 40, thereby improving the production efficiency of the paper sheet 100 and reducing the cost.

[0042] In this embodiment, the fixing member 42 is provided with a guide rail 421 in a direction perpendicular to the sliding direction of the paper conveying mechanism 30, and the connecting member 411 of the bending assembly 41 is provided with a groove 300 that matches the guide rail 421. The groove 300 can be embedded in the guide rail 421 and can slide along the guide rail 421.

[0043] For details, please refer to Figure 4 As shown, the fixing member 42 is provided with a guide rail 421 in the direction perpendicular to the sliding direction of the paper conveying mechanism 30, which can minimize the space occupied by the bending mechanism 40 and shorten the sliding distance of the connecting member 411, thereby reducing space costs and improving production efficiency. The connecting member 411 can be directly slid by the guide rail 421 in conjunction with the slide groove 300, which is convenient and quick, and facilitates the automated operation of the connecting member 411 by the drive device.

[0044] In this embodiment, the bending assembly 41 further includes a telescopic cylinder 413. The telescopic cylinder 413 includes a telescopic cylinder body 4131 and movable parts 4132 that are telescopically disposed at both ends of the telescopic cylinder body 4131. The telescopic cylinder body 4131 is fixedly mounted on the connector 411, and the two bending parts 412 are respectively fixedly connected to the movable parts 4132.

[0045] For details, please refer to Figure 4As shown, the two bending components 412 are fixedly connected to the movable component 4132, which can prevent the paper 100 from deforming or being damaged due to uneven force. The bending component 412 is raised and lowered along the height direction of the frame 10 by the telescopic cylinder body 4131 and the movable component 4132. This can avoid the bending component 412 being arranged on the frame 10 in other ways, which would increase the overall space of the bending mechanism 40 and the number of bending steps of the paper 100. In addition, the cylinder drive method has a fast response and stable operation, which is convenient for automated control and improves bending efficiency. At the same time, the overall structure is integrated on the connector 411, saving the storage space 200.

[0046] In this embodiment, each bending member 412 of the bending assembly 41 includes a limiting member 4121 and a limiting protrusion 4122 protruding from the limiting member 4121. The limiting member 4121 is fixedly connected to the movable member 4132. The limiting protrusion 4122 and the limiting member 4121 form a limiting groove 400 for limiting the paper piece 100. When the connecting member 411 slides to the point where the paper piece 100 is located in the limiting groove 400, the telescopic cylinder body 4131 is compressed to drive the two bending members 412 to move closer to each other and squeeze the paper piece 100 to bend.

[0047] For details, please refer to Figure 4 As shown, the limiting groove 400 can precisely engage the edge of the paper piece 100, ensuring that the paper piece 100 remains in a fixed position during bending, preventing the paper piece 100 from sliding or shifting, and improving the accuracy and consistency of bending; when the connecting piece 411 moves into place, the telescopic cylinder body 4131 can be quickly compressed, so that the two bending pieces 412 can work together to squeeze the paper piece 100 through the limiting groove 400 to achieve efficient bending.

[0048] In this embodiment, the paper conveying mechanism 30 includes a support member 31 slidably disposed on the base plate 11 and a clamping assembly 32 fixed at both ends of the support member 31. A positioning member 311 is fixed in the middle of the support member 31 for positioning and placing the paper piece 100. The clamping assembly 32 includes a fixing part 321 fixed at the end of the support member 31 and a clamping member 322 telescopically connected to the fixing part 321. The clamping member 322 is used to clamp and fix the paper piece 100.

[0049] For details, please refer to Figure 3As shown, the positioning member 311 ensures that the clamping mechanism 20 accurately places the paper sheet 100. The clamping component 32, through the telescopic cooperation of the fixing part 321 and the clamping member 322, can extend to the vicinity of the paper sheet 100 and clamp the paper sheet 100 after it is placed on the positioning member 311, thereby facilitating the bending mechanism 40 to bend the paper sheet 100. After the paper sheet 100 completes the bending step, the support member 31 can slide away from the bending mechanism 40 to transport the paper sheet 100 to the paper sheet forming device 3, thereby achieving a compact layout of the paper conveying mechanism 30 and the bending mechanism 40, thereby reducing the overall space occupied by the paper sheet bending feeding device 1, and enhancing the continuity of the paper sheet 100 transportation and bending process, facilitating automated operation and improving the production efficiency of the paper sheet 100.

[0050] In this embodiment, a limiting component 33 fixed on the support member 31 is also included. The limiting component 33 includes a lifting cylinder 331 fixed on the support member 31, a second telescopic cylinder 332 that is movably disposed on the lifting cylinder 331, and a limiting shaft 333 that is telescopically connected to the second telescopic cylinder 332. The limiting shaft 333 is used to abut against the side of the paper sheet 100.

[0051] For details, please refer to Figure 3 As shown, the limiting component 33, through the cooperation of the lifting cylinder 331 and the second telescopic cylinder 332, can realize the vertical lifting and horizontal telescopic movement of the limiting shaft 333. When the clamping mechanism 20 transports the paper sheet 100, the limiting shaft 333 can be located below the paper sheet 100, thereby avoiding obstructing the straight transport of the paper sheet 100. When the paper sheet 100 is transported and placed on the positioning member 311, the lifting cylinder 331 can drive the limiting shaft 333 to rise to abut the side of the paper sheet 100, thereby maximizing the utilization of the space and reducing space costs. Furthermore, the limiting shaft 333 ensures the bending effect of the paper sheet 100, preventing the paper sheet 100 from bending in other directions and affecting the subsequent forming of the paper sheet 100.

[0052] In this embodiment, the axial direction of the limiting shaft 333 is perpendicular to the extension and retraction direction of the bending member 412.

[0053] For details, please refer to Figure 3 As shown, the axial direction of the limiting shaft 333 is perpendicular to the extension and retraction direction of the bending component 412, so that the lateral limiting effect of the limiting shaft 333 and the bending and pressing action of the bending component 412 do not interfere with each other, ensuring the bending quality of the paper sheet 100, improving space utilization, facilitating the sequential execution of the limiting and bending steps of the paper sheet 100, and improving the production efficiency of the paper sheet 100.

[0054] In this embodiment, the base plate 11 is provided with a second guide rail 111, and the end of the support member 31 is provided with a second guide groove 500 that matches the second guide rail 111. The second guide groove 500 can be embedded in the second guide rail 111 and can slide along the second guide rail 111.

[0055] For details, please refer to Figure 2 and Figure 3 As shown, the cooperation of the two guide rails 421 and the second guide groove 500 enables the support member 31 to slide smoothly along the base plate 11, ensuring the linear transport accuracy and smoothness of the paper transport mechanism 30 in transporting the paper sheet 100, facilitating disassembly and positioning, thereby improving the production efficiency of the paper sheet 100.

[0056] This application also provides a paper sheet 100 forming fixture, including a paper sheet conveying device 2 for supplying the paper sheet 100, a paper sheet forming device 3, and a paper sheet bending feeding device 1 as described in any of the above embodiments, wherein the paper sheet bending feeding device 1 is disposed between the paper sheet conveying device 2 and the paper sheet forming device 3.

[0057] For details, please refer to Figure 1 As shown, the paper bending and feeding device 1 can realize the conveying and bending of paper 100 at the same station, which not only reduces the additional production space occupied by the additional bending mechanism 40 and reduces production costs, but also ensures the production speed of paper 100, and facilitates automated operation, thereby improving the production efficiency of paper 100.

[0058] In this embodiment, the paper sheet 100 forming fixture further includes a paper separating mechanism 4. The paper separating mechanism 4 includes a support part 401 fixed on the paper sheet conveying device 2 and two rotating shafts 402 rotatably disposed on the support part 401. Each rotating shaft 402 is provided with two paper separating blocks 4021 spaced apart in the circumferential direction. The width between the two rotating shafts 402 is greater than or equal to the width of the paper sheet 100, and the two paper separating blocks 4021 on each rotating shaft 402 abut against the paper sheet 100 with the rotation interval of the rotating shaft 402.

[0059] For details, please refer to Figure 5 As shown, the width between the two rotating shafts 402 is greater than or equal to the width of the paper 100, which ensures that the paper separating mechanism 4 can completely separate the paper 100 on the conveying device. The two paper separating blocks 4021 on the rotating shaft 402 abut against the paper 100 at intervals as the rotating shaft 402 rotates, so that the paper 100 on the conveying device can be separated into paper 100 of a preset thickness as the rotating shaft 402 rotates. This facilitates the subsequent clamping mechanism 20 to clamp and transport the paper 100, avoids the clamping mechanism 20 from being unable to completely clamp the paper 100 for transport due to too many separated paper 100s, and also avoids the clamping mechanism 20 clamping too many paper 100s, which would affect the bending effect of the paper 100.
