Description

Technical Field

[0001] The present application relates to the technical field of punching machines, and in particular to a roller body drilling device. Background Art

[0002] Papermaking machine is a paper manufacturing equipment, which is mainly composed of flow structure, forming structure, pressing structure and drying structure. As the core equipment of paper production, the design and operation process of papermaking machine are highly complex and sophisticated, and it is designed to transform pulp into the final paper product through a series of physical and chemical processes;

[0003] The main function of the pressing structure is to further dehydrate the formed wet paper sheets. In the paper manufacturing process, the wet paper sheets contain a large amount of water after they are formed. This water needs to be removed by pressing to improve the dryness and strength of the paper. In order to achieve effective dehydration, a pressing roller is provided in the pressing structure. The pressing roller is designed to be able to apply sufficient pressure to the wet paper sheets. At the same time, considering the flexibility of the paper and avoiding damage, through holes are opened on the pressing roller for this purpose. These through holes allow the water in the wet paper sheets to be quickly discharged when under pressure and enter the internal space of the pressing roller or the subsequent drainage system.

[0004] For example, the patent with publication number CN213224391U specifically discloses a drilling device for a papermaking press roller. By providing an arc plate for buffering, the arc plate and the press roller are first contacted before the drill rig contacts the press roller. As a result, when the drill rig drills holes in the press roller, the vibration generated during drilling is buffered, thereby maintaining sufficient stability and improving the precision and accuracy of drilling.

[0005] In the above patent, the drilling device is provided with a buffer device so that the vibration generated by drilling can be buffered during drilling. However, the drilling device performs one-time drilling and forming during drilling. This forming method requires extremely high operating accuracy and equipment stability. If the equipment accuracy is insufficient or the operation is improper, it is easy to cause problems such as drilling position offset and inconsistent hole size. At the same time, in a one-time drilling and forming process, once drilling begins, it is difficult to correct. If the drilling machine is offset or broken during the drilling process, the entire component may be scrapped. Therefore, it is necessary to provide a roller body drilling device with a pre-punching mechanism to solve the above problems.

[0043] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0044] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0045] Embodiment 1: This embodiment specifically describes the basic structure and working principle of the roller body drilling device, specifically:

[0046] like Figure 1-Figure 4 As shown, the present application provides a roller body drilling device, comprising a mounting frame 1, the mounting frame 1 is arranged in a paper machine production plant, and a workbench 11 is arranged on the mounting frame 1, and a drilling mechanism 2 is installed on the workbench 11, and the drilling mechanism 2 is used to perform drilling processing on a press roller (hereinafter referred to as a press roller) in the paper machine;

[0047] The drilling mechanism 2 includes a base 21, which is fixedly mounted on the top of the workbench 11. A support assembly 3 is fixedly arranged on the base 21. The support assembly 3 is used to place and fix the press roll to be processed. The support assembly 3 includes a fixing table 31, and a mounting groove 311 is arranged on the top of the fixing table 31. The size of the mounting groove 311 is adapted to the size of the press roll.

[0048] At the same time, a connecting plate 32 is installed on the side of the base 21 away from the fixed platform 31, and a rotating motor 33 is fixedly installed on the connecting plate 32. The output end of the rotating motor 33 passes through the connecting plate 32 and is arranged in the direction of the fixed platform 31. At the same time, a roller 331 is fixedly installed on the output end. A plurality of groups of feeding trays 34 are fixedly installed on the roller 331. A plurality of groups of notches 341 are arranged on the feeding tray 34, and the size of the notches 341 is the same as the size of the mounting groove 311, and the notches 341 and the mounting groove 311 are on the same horizontal line. The pressing roller can be smoothly moved from the mounting groove 311 on the fixed platform 31 to the notches 341 of the feeding tray 34 under the action of external force.

[0049] A feeding part 4 is provided on one side of the support assembly 3, and the feeding part 4 is used to convey the unprocessed squeezing roller into the support assembly 3. The feeding part 4 includes a storage box 41, and the storage box 41 is detachably mounted on one side of the workbench 11. The storage box 41 is used to store the squeezing roller after processing. At the same time, a discharge box 42 is fixedly mounted on the top of the storage box 41, and the discharge box 42 is used to store the squeezing roller to be processed. A through notch is provided on one side of the discharge box 42 close to the bottom of the workbench 11, and a sealing door is provided in the notch. When the sealing door is opened, the squeezing roller is suitable for rolling out from the notch, and the horizontal height of the notch is greater than the horizontal height of the mounting groove 311.

[0050] At the same time, a first tray 43 is arranged between the material box 42 and the fixed table 31. One end of the first tray 43 is fixedly mounted on the bottom of the material box 42, and the other end is fixedly mounted on the outside of the fixed table 31. At the same time, since the horizontal height of the material box 42 is greater than the horizontal height of the fixed table 31, the first tray 43 is installed from high to low when installed. When processing is required, the sealing door can be opened by external control, so that the pressing roller rolls from the material box 42 along the first tray 43 to the installation groove 311 on the fixed table 31, which is convenient for subsequent processing work;

[0051] At the same time, a second tray 44 is also obliquely arranged between the material storage box 41 and the connecting plate 32 . The higher end of the second tray 44 is fixedly mounted on the connecting plate 32 , and the lower end is mounted on the top of the material storage box 41 and communicated with the interior of the material storage box 41 .

[0052] like Figure 2 As shown, a support column 22 is fixedly arranged on one side of the base 21, a first cylinder 23 is fixedly arranged on the top of the support column 22, a punching part 5 is installed on the bottom of the first cylinder 23, and the punching part 5 is used to punch holes on the pressing roller placed on the support assembly 3. The punching part 5 includes a crossbeam 51, which is fixedly installed on the output end of the first cylinder 23, and a centrally penetrating convex block 511 is arranged on one side of the crossbeam 51, and a sliding rod 221 is arranged on the support column 22, and the convex block 511 is slidably installed on the sliding rod 221, so that the crossbeam 51 is suitable for moving along the height direction of the sliding rod 221 under the drive of the first cylinder 23;

[0053] At the same time, a plurality of first drilling machines 52 are arranged on the crossbeam 51. The positions of the first drilling machines 52 correspond to the positions of the fixed platform 31. The first drilling machines 52 are used to perform preliminary drilling positioning on the pressing roller to facilitate subsequent drilling processing.

[0054] At the same time, multiple groups of second drilling rigs 53 are arranged on one side of the multiple groups of first drilling rigs 52. The second drilling rigs 53 are arranged corresponding to the position of the feed tray 34, and are used to accurately punch holes in the pressing roller on the top of the feed tray 34. At the same time, in this embodiment, the rotation angle of the rotating motor 33 is fixed each time. Each time the feed tray 34 rotates driven by the rotating motor 33, there is a group of notches 341 facing the direction of the second drilling rig 53.

[0055] like Figure 2 , Figure 7-Figure 8 As shown, in order to keep the pressing roller stable during punching, a stabilizing structure 6 is further provided in the device, and the stabilizing structure 6 includes a plurality of clamping plates 61 arranged on the mounting groove 311, and a first spring is arranged between the clamping plates 61 and the mounting groove 311. When the pressing roller slides from the first tray 43 to the top of the fixing platform 31, the pressing roller will contact the clamping plates 61 and be buffered by the first spring, thereby reducing the damage of the pressing roller due to collision.

[0056] Meanwhile, a fixing plate 62 is provided between every two groups of first drilling machines 52, and the fixing plate 62 is fixedly mounted on the cross beam 51. At the same time, a plug rod 63 is fixedly mounted on the side of the fixing plate 62 away from the cross beam 51, and a pressing plate 64 is provided at the bottom of the plug rod 63. A second spring is provided between the pressing plate 64 and the multiple groups of plug rods 63. The pressing plate 64 is used to contact with the top of the pressing roller. At the same time, in order not to affect the drilling, multiple groups of through grooves 641 are provided on the pressing plate 64, and the number of the through grooves 641 matches the number of the first drilling machines 52;

[0057] When drilling is required for the pressing roller, the sealing door at the notch of the material box 42 is first opened to allow the pressing roller to roll out of the notch and roll down along the first tray 43 to the mounting groove 311 on the top of the fixed platform 31. At this time, the pressing roller will be lifted by the multiple groups of clamping plates 61 on the mounting groove 311, and then the first cylinder 23 is controlled to drive the crossbeam 51 to move toward the pressing roller. At this time, the pressing plate 64 at the bottom of the insertion rod 63 will first contact the pressing roller, and with the continuous movement of the first cylinder 23, the pressing roller is clamped between the clamping plate 61 and the pressing plate 64, and the first spring and the second spring on the clamping plate 61 and the pressing plate 64 will also be in a compressed state, so that the pressing roller is fixed more tightly.

[0058] When the pressure plate 64 contacts the pressing roller, as the first cylinder 23 continues to move, the second spring on the pressure plate 64 will gradually compress, causing the distance between the first drill 52 and the pressure plate 64 to gradually decrease until the drill bit of the first drill 52 passes through the through groove 641 on the pressure plate 64 and contacts the pressing roller, thereby completing the pre-punching of the pressing roller.

[0059] like Figure 4 , Figure 7As shown, a connecting frame 35 is provided on one side of the fixed platform 31 away from the feeding tray 34, a second cylinder 36 is fixedly installed on the outer side of the connecting frame 35, and the output end of the second cylinder 36 passes through the connecting frame 35 and is fixedly installed with a push block 37, the height of the push block 37 is greater than the height of the mounting groove 311, when the pre-punching of the pressing roller is completed, the pressing roller can be pushed to the notch 341 on the feeding tray 34 by controlling the second cylinder 36;

[0060] It can be understood that, in this embodiment, the length of the fixed platform 31 is adapted to the length of the press roll, and the distance between the feed tray 34 and the connecting plate 32 near the fixed platform 31 is adapted to the size of the press roll, so that after the press roll moves, the first drilling machine 52 and the second drilling machine 53 have the same processing position on the press roll;

[0061] like Figure 4-Figure 6 As shown, the feeding tray 34 includes two groups of chucks 342, and each group of chucks 342 includes a notch 341, and a connecting column 343 is fixedly installed between the two groups of chucks 342, and the connecting column 343 is used to be fixedly connected to the roller 331, so that the two groups of chucks 342 are suitable for rotating under the drive of the roller 331;

[0062] At the same time, a plurality of brackets 24 are arranged on the base 21 at positions corresponding to the feed trays 34. The brackets 24 and the connecting columns 343 do not contact each other, and a clamp 25 is fixedly installed on the top of the bracket 24. The size of the clamp 25 after opening is adapted to the size of the notch 341. In the present embodiment, the clamp 25 is a traditional mechanical clamp, which will not be elaborated herein.

[0063] When the squeezing roller is moved from the fixed platform 31 to the feeding tray 34 by the second cylinder 36, the clamping claw 25 can be started to clamp the squeezing roller, and then the first cylinder 23 is controlled to drive the second drilling machine 53 to approach the squeezing roller, and then the squeezing roller is punched;

[0064] When the punching is completed, the clamp 25 releases the pressing roller. At this time, the rotating motor 33 can be controlled to drive the feed plate 34 to rotate, and then drive the pressing roller to rotate toward the second tray 44. At this time, the processed pressing roller can roll from the notch 341 into the second tray 44, and move along the second tray 44 to the storage box 41, thereby completing the storage of the pressing roller.

[0065] Embodiment 2: After the press roller is pre-punched, the press roller needs to be moved by the second cylinder 36. However, if the pre-punching depth of the press roller does not meet the requirements, the punching accuracy may deviate during the formal punching. Therefore, in this embodiment, the second cylinder 36 is removed, and improvements are made to the punching part 5. Specifically:

[0066] like Figure 9-11 As shown, a third spring is provided between the push block 37 and the connecting frame 35, and the push block 37 is installed on the connecting frame 35 through the third spring. This is the initial position of the push block 37. At the same time, a mounting block (not shown in the figure) is provided on the top of the push block 37. The size of the mounting block is adapted to the size of the mounting groove 311, so that the push block 37 moves along the direction of the mounting groove 311 when moving.

[0067] At the same time, an adjusting rod 8 is fixedly installed on the top of the push block 37, a hook block 81 is installed on the top of the adjusting rod 8, and an elastic member (not shown in the figure) is arranged between the hook block 81 and the adjusting rod 8, and a plug-in column 65 is fixedly installed on the side of the fixing plate 62 close to the cross beam 51, and a limit plate 7 is fixedly installed on the bottom of the plug-in column 65, and the limit plate 7 is used to adjust the position of the push block 37;

[0068] The limiting plate 7 is provided with a plurality of channels, including a first channel 71. The bottom of the first channel 71 is provided with a first opening allowing the hook block 81 to pass through. The adjusting rod 8 can enter the first channel 71 through the first opening and slide in the first channel 71. At this time, the elastic member is in a compressed state.

[0069] At the same time, a stationary point 73 for limiting the hooking block 81 is provided at one end of the first channel 71 away from the first opening. When the limiting plate 7 continues to move toward the direction of the pressing roller driven by the first cylinder 23, the hooking block 81 will enter the first channel 71 from the first opening and slide in the first channel 71. During this process, the first drilling machine 52 will also continue to move toward the direction of the pressing roller and perform pre-drilling operation on the pressing roller. When the hooking block 81 reaches the stationary point 73, the hooking block 81 will be limited by the stationary point 73. At this time, the first drilling machine 52 has completed the pre-drilling of the pressing roller.

[0070] At the same time, a second channel 72 is obliquely arranged on one side of the first channel 71, and the length of the second channel 72 is adapted to the length of the pressing roller, and one end of the second channel 72 is connected to the first channel 71, and there is a certain distance between the connection between the second channel 72 and the first channel 71 and the stationary point 73, and at the same time, the second channel 72 has a second opening at one end away from the first channel 71, and the groove bottom height of the first channel 71 is higher than the groove bottom height of the second channel 72, and when the hooking block 81 reaches the stationary point 73, due to the limiting influence of the stationary point 73, the limiting plate 7 cannot continue to move toward the pressing roller, and the pre-punching operation of the pressing roller can be completed at this time;

[0071] When the hook block 81 is located in the stationary point 73, since the bottom height of the first channel 71 is higher than the bottom height of the second channel 72, when the hook block 81 enters the connection between the second channel 72 and the first channel 71 from the first channel 71, the elastic member will be released and drive the hook block 81 to move into the second channel 72, so that after the hook block 81 enters the second channel 72 from the first channel 71, it cannot return from the second channel 72 to the first channel 71;

[0072] When the pre-drilling is completed, the first cylinder 23 drives the first drill 52 to move in the direction away from the squeezing roller. At this time, the limit plate 7 will move synchronously. Since the bottom height of the first channel 71 is higher than the bottom height of the second channel 72, the hook block 81 will move from the stationary point 73 to the second channel 72. As the limit plate 7 continues to move, the inclined second channel 72 will generate a lateral pressure on the hook block 81, thereby causing the adjustment rod 8 to shift laterally, thereby driving the push block 37 to move in the direction of the feed tray 34. At this time, the third spring between the push block 37 and the feed tray 34 is in a stretched state, thereby causing the squeezing roller on the fixed table 31 to be moved onto the feed tray 34.

[0073] When the pressing roller is sent to the feeding plate 34, the hooking block 81 will reach the second opening on the second channel 72 and disengage from the second opening. At this time, the third spring loses the force applied to it by the second channel 72 and shrinks and resets, and drives the pushing block 37 to return to its initial position. At this time, the feeding process of the pressing roller is completed.

[0074] It should be noted that when the pressing roller is not completely pre-drilled, the hook block 81 will only move in the first channel 71 and cannot reach the inside of the stationary point 73, so that the first drilling rig 52 continues to drill the pressing roller until the pre-drilling depth reaches the requirement. Only then will the hook block 81 enter the stationary point 73, thereby realizing the subsequent pushing process and improving the drilling quality of the pressing roller.

[0075] Embodiment 3: Since the pressing roller may rotate when being pushed by the push block 37, which may cause the position of the pre-punching hole to deviate from that of the formal punching hole, improvements are made to the push block 37, specifically:

[0076] like Figure 12-13 As shown, a slot 74 is provided on one side of the push block 37 close to the fixed platform 31. The size of the slot 74 is slightly larger than the size of the pressing roller. A silicone layer 741 is provided in the slot 74. In this embodiment, the silicone layer 741 has a certain thickness.

[0077] At the same time, the length of the fixed platform 31 is set to be slightly smaller than the length of the squeezing roller, so that after the squeezing roller falls from the first tray 43 into the mounting groove 311 on the fixed platform 31, the end of the squeezing roller close to the push block 37 will fall into the card slot 74 in the push block 37, but due to the setting of the silicone layer 741, the squeezing roller will not be completely immersed in the card slot 74, and when the pre-punching starts, as the pressing plate 64 continues to move, it will contact the squeezing roller, and at this time, the end of the squeezing roller located in the card slot 74 will be squeezed by the pressing plate 64 and the silicone layer 741 will be deformed until the squeezing roller completely enters the card slot 74, and at this time, the deformation of the silicone layer 741 effectively limits the rotation of the squeezing roller, ensuring the accuracy of the punching;

[0078] Since the silicone layer 741 has a certain thickness, it not only ensures sufficient buffering effect to prevent the pressing roller from directly contacting the slot 74 and causing damage, but also provides sufficient resistance when being squeezed to limit the rotation of the pressing roller, thereby ensuring that the pressing roller maintains a stable positioning.

[0079] When the pre-punching is completed, the pressing roller will be pushed into the feed tray 34 by the push block 37. When the pressing roller completely enters the multiple groups of notches 341, the clamping claw 25 will clamp the pressing roller, and the push block 37 will be separated from the pressing roller under the pulling force of the third spring and return to the initial position to prepare for the next processing.

[0080] In summary, the device is provided with a punching part 5 that can automatically push and feed materials, so that the pressing roller can be automatically fed into the next process for formal punching after pre-punching, thereby improving the overall efficiency and automation level of the drilling device, reducing manual intervention, and improving production efficiency.

[0081] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
