Description

Technical Field

[0001] The utility model relates to the technical field of plate surface treatment, in particular to a plate surface treatment feeding mechanism. Background Art

[0002] The paper sticker machine is a device that uses hot pressing technology to hot-press the paper attached to the surface of the sheet material at high temperature and high pressure. It is mainly suitable for sticking various colors of wood grain paper, paint-free paper, aluminum foil paper, solid wood veneer, etc. on the surface of various density boards, medium-density fiberboards, and fireproof boards to provide a beautiful surface effect.

[0003] At present, the sheet materials are usually fixed by suction using a suction cup, and then moved to the sticker skinning station by a robotic arm. However, this traditional suction cup vacuum suction fixing method has some problems. For example, the surface of the sheet material is too rough, which may lead to abnormal suction, and the sheet material needs to be sucked up first and then moved to the designated position, which is a time-consuming process. In addition, the sucked sheet material may fall from the suction cup during a power outage, posing a safety hazard of hitting people, and will also cause damage and loss of the sheet material. Utility Model Content

[0004] The utility model aims at the technical problems existing in the prior art and provides a sheet material surface treatment feeding mechanism to solve the problem that the sheet material surface is too rough and may not be sucked normally, and the sheet material needs to be sucked up first and then moved to a specified position, which is a time-consuming process. In addition, the sucked sheet material may fall from the suction cup during a power outage, posing a safety hazard of hitting people, and also causing damage and loss of the sheet material.

[0005] The utility model solves the above-mentioned technical problem with the following technical solution: a sheet material surface treatment feeding mechanism, comprising:

[0006] A lifting assembly, wherein the lifting assembly moves in a direction perpendicular to the ground and is used to drive the sheet material to move in a direction perpendicular to the ground;

[0007] A pushing assembly, which is arranged above the lifting assembly and moves in a direction away from or close to the lifting assembly;

[0008] The hook assembly is suspended above the lifting assembly and is held against the side wall of the sheet material. The hook assembly is arranged on the moving end of the pushing assembly and is used to drive the sheet material to move in a direction away from or close to the lifting assembly.

[0009] The beneficial effects of the utility model are:

[0010] 1) By introducing a lifting component, a stack of sheet materials is placed on it, and the hook component is used to support the sheet material on the top layer first, and then the push component is used to drive the hook component to move away from the lifting component, while driving the sheet material to move away from the lifting component at the same time. There is no need to use the traditional suction cup vacuum suction method, thereby reducing the suction and movement process steps and improving the efficiency of feeding the sheet material.

[0011] 2) Since it no longer relies on vacuum suction by the suction cup, there is no need to worry about the problem that the sheet cannot be sucked due to the rough surface. At the same time, there is no risk of the sucked sheet falling from the air during a power outage. This not only improves the efficiency of feeding the sheet, but also reduces safety risks, reduces damage and loss of the sheet, and provides a more stable and reliable workflow for hot pressing. Therefore, the feeding mechanism improves production efficiency while also improving work safety and reducing production costs.

[0012] On the basis of the above technical solution, the present invention can also be improved as follows.

[0013] Furthermore, it also includes a detection component for detecting the number of sheets stored on the jacking component.

[0014] Furthermore, the detection component includes a "T"-shaped fixing frame, photoelectric sensor 1 and photoelectric sensor 2, wherein photoelectric sensor 1 and photoelectric sensor 2 are respectively arranged on one side of the fixing frame and electrically connected to the lifting assembly, and the horizontal height of the optical axis of photoelectric sensor 1 is at most a thickness of a sheet away from the hook assembly, and photoelectric sensor 2 is located below photoelectric sensor 1 and faces the sheet on the lifting assembly.

[0015] The beneficial effect of adopting the above further scheme is that the detection component realizes real-time detection and control of the sheet material to ensure that the sheet material on the jacking component can always be driven to move by the hook assembly, thereby improving the efficiency of the entire process of feeding the sheet material.

[0016] Specifically, photoelectric sensor 1 and photoelectric sensor 2 are arranged on one side of the fixing frame and are electrically connected to the lifting assembly, wherein the horizontal height of the optical axis of photoelectric sensor 2 is lower than the horizontal height of the optical axis of photoelectric sensor 1, and the horizontal height of photoelectric sensor 1 is at most a sheet thickness away from the hook assembly. When the hook assembly drags a sheet below to move, there is a gap of the thickness of the sheet between the hook assembly and the sheet on the lifting assembly. At this time, the optical axis emitted by the transmitting end of photoelectric sensor 1 is received by its receiving end, so that normal signal emission is completed between them, thereby satisfying the situation of detecting that there is no sheet, that is, the receiving end of photoelectric sensor 1 responds and provides the signal to the lifter of the lifting assembly;

[0017] Once the photoelectric sensor fails to detect the existence of the sheet, the lifting assembly is triggered, driving the sheet on the lifting assembly to rise by the thickness of the sheet. This process fills the gap between the hook assembly and the sheet on the lifting assembly, allowing the sheet on the lifting assembly to continue to be located on one side of the hook assembly, ensuring that it can be continuously dragged and moved by the hook assembly.

[0018] Therefore, the design of the detection component effectively ensures the stability and continuity of the feeding sheet, improves the production efficiency of the entire sticker machine, reduces downtime in practical applications, improves the operating efficiency of the production line, and at the same time reduces the need for manual operation and reduces the risk of potential human errors.

[0019] Furthermore, the pushing assembly includes a slide rail, a crossbeam, a driving member for driving the crossbeam to move on the slide rail, and two support frames arranged in mirror symmetry with each other, the two support frames are respectively located on both sides of the jacking assembly, the slide rail is arranged on the top of the two support frames, and the crossbeam slides on the slide rail.

[0020] Furthermore, the driving member includes a gear, a rack and a driving motor, the rack is located on one side of the slide rail and fixed on the supporting frame, the gear is rotatably connected to both sides of the beam through a rotating shaft, and the gear is meshed on the rack, the driving end of the driving motor is connected to one side of the gear, and one side of the driving motor is fixed on the beam.

[0021] The beneficial effect of adopting the above-mentioned further scheme is that, through the meshing relationship between the gear and the rack, the driving motor drives the gear to roll on the rack, thereby realizing the sliding action of the beam on the slide rail. This structure can provide precise control and realize a smooth pushing process, ensuring that the sliding action of the beam will not cause excessive vibration or swing, so that the pushing component moves according to the predetermined path and speed, which helps to improve the stability and accuracy of the system.

[0022] Furthermore, the hook assembly includes a drag plate and a pressure rod, the drag plate is fixed on one side of the cross beam, and the pressure rod is detachably connected near the bottom end of the drag plate.

[0023] The beneficial effect of adopting the above-mentioned further scheme is that, by connecting the pressure rod near the bottom end of the drag plate, a certain length is reserved at the bottom end of the drag plate. The reserved length can be the thickness of a sheet material. When the bottom of the drag plate is against the sheet material to move, the pressure rod can be pressed on the sheet material to ensure that the sheet material will not warp up during the movement, which helps to maintain the stability of the sheet material and prevent irregular movement or displacement caused by warping, thereby affecting the normal feeding of the sheet material.

[0024] Furthermore, a buffer pad is provided on one side of the bottom end of the drag plate.

[0025] The beneficial effect of adopting the above-mentioned further scheme is that the buffer pad arranged on one side of the bottom end of the drag plate helps to convert the rigid contact between the sheet and the drag plate into flexible contact, which can effectively reduce the impact force generated during the movement, and the impact force may cause damage to the surface of the sheet. By using the buffer pad, the impact force can be reduced. At the same time, the presence of the buffer pad can prevent scratches or damage to the surface of the sheet. In traditional rigid contact, scratches are easily generated on the surface of the sheet due to the direct contact of hard materials. By adopting the buffer pad, the contact mode is converted into flexible contact, which helps to avoid such damage and improves the quality and appearance of the sheet.

[0026] Furthermore, the lifting assembly includes a lifter. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0035] The paper sticker machine is a device that uses hot pressing technology to hot-press the paper attached to the surface of the sheet material at high temperature and high pressure. It is mainly suitable for sticking various colors of wood grain paper, paint-free paper, aluminum foil paper, solid wood veneer, etc. on the surface of various density boards, medium-density fiberboards, and fireproof boards to provide a beautiful surface effect.

[0036] At present, the sheet materials are usually fixed by suction using a suction cup, and then moved to the sticker skinning station by a robotic arm. However, this traditional suction cup vacuum suction fixing method has some problems. For example, the surface of the sheet material is too rough, which may lead to abnormal suction, and the sheet material needs to be sucked up first and then moved to the designated position, which is a time-consuming process. In addition, the sucked sheet material may fall from the suction cup during a power outage, posing a safety hazard of hitting people, and will also cause damage and loss of the sheet material.

[0037] In response to this, the utility model proposes a sheet material surface treatment feeding mechanism to solve the above-mentioned problem.

[0038] The utility model provides the following preferred embodiments

[0039] Example 1

[0040] like Figure 1-Figure 5 As shown, a sheet material surface treatment feeding mechanism comprises:

[0041] A lifting assembly 100, the lifting assembly 100 is displaced in a direction perpendicular to the ground, and is used to drive the sheet material to move in a direction perpendicular to the ground;

[0042] A pushing assembly 200, which is disposed above the lifting assembly 100 and moves in a direction away from or close to the lifting assembly 100;

[0043] The hook assembly 300 is suspended above the lifting assembly 100 and is held against the side wall of the sheet material. The hook assembly 300 is disposed on the moving end of the pushing assembly 200 and is used to drive the sheet material to move in a direction away from or close to the lifting assembly 100.

[0044] By introducing the lifting assembly 100, a stack of sheet materials is placed on it, and the hook assembly 300 is used to first hold the sheet material on the top layer, and then the push assembly 200 is used to drive the hook assembly 300 to move in a direction away from the lifting assembly 100, and at the same time drive the sheet material to move in a direction away from the lifting assembly 100, without using the traditional suction cup vacuum suction method, thereby reducing the suction and movement process steps and improving the efficiency of feeding the sheet material;

[0045] Since it no longer relies on vacuum suction by suction cups, there is no need to worry about the problem of the sheet material being unable to be sucked up due to its rough surface. At the same time, there is no risk of the sucked sheet material falling from the air during a power outage. This not only improves the efficiency of feeding the sheet material, but also reduces safety risks, reduces damage and loss of the sheet material, and provides a more stable and reliable workflow for hot pressing processing. Therefore, the feeding mechanism improves production efficiency while also improving work safety and reducing production costs.

[0046] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, it also includes a detection component 400 for detecting the number of sheets stored on the jacking component 100, and the detection component 400 includes a "T"-shaped fixing frame 401, a photoelectric sensor 1 402 and a photoelectric sensor 2 403, the photoelectric sensor 1 402 and the photoelectric sensor 2 403 are respectively arranged on one side of the fixing frame 401 and are electrically connected to the jacking component 100, and the horizontal height of the optical axis of the photoelectric sensor 1 402 is at most a sheet thickness distance from the hook claw component 300, and the photoelectric sensor 2 403 is located below the photoelectric sensor 1 and faces the sheet on the jacking component 100; the detection component 400 realizes real-time detection and control of the sheet to ensure that the sheet on the jacking component 100 can always be driven to move by the hook claw component 300, thereby improving the efficiency of the entire process of feeding the sheet;

[0047] Specifically, the photoelectric sensor 1 402 and the photoelectric sensor 2 403 are arranged on one side of the fixing frame 401 and are electrically connected to the lifting assembly 100, wherein the horizontal height of the optical axis of the photoelectric sensor 2 403 is lower than the horizontal height of the optical axis of the photoelectric sensor 1 402, and the horizontal height of the optical axis of the photoelectric sensor 1 402 is at most a sheet thickness away from the hook assembly 300. When the hook assembly 300 drags a sheet below to move, a gap of the thickness of the sheet is generated between the hook assembly 300 and the sheet on the lifting assembly 100. At this time, the optical axis emitted by the transmitting end of the photoelectric sensor 1 402 is received by its receiving end, so that normal signal transmission is completed between them, thereby satisfying the situation of detecting that there is no sheet, that is, the receiving end of the photoelectric sensor 1 402 responds and provides the signal to the lifting assembly 100;

[0048] Once the photoelectric sensor 402 fails to detect the existence of the sheet material, the lifting assembly 100 is triggered and responds to drive the sheet material on the lifting assembly 100 to rise by the thickness of the sheet material. This process fills the gap between the hook assembly 300 and the sheet material on the lifting assembly 100, so that the sheet material on the lifting assembly 100 can continue to be located on one side of the hook assembly 300, so as to ensure that it can be continuously dragged and moved by the hook assembly 300.

[0049] Therefore, the design of the detection component 400 effectively ensures the stability and continuity of the fed-in sheet material, improves the production efficiency of the entire sticker machine, reduces downtime in actual applications, improves the operating efficiency of the production line, and at the same time reduces the need for manual operation and reduces the risk of potential human errors.

[0050] In this embodiment, Figure 1 , Figure 2 and Figure 3As shown, the pushing assembly 200 includes a slide rail 210, a beam 220, a driving member 230 for driving the beam 220 to move on the slide rail 210, and two carrier frames 240 arranged in mirror symmetry with each other. The two carrier frames 240 are respectively located on both sides of the jacking assembly 100, the slide rail 210 is arranged on the top of the two carrier frames 240, the beam 220 slides on the slide rail 210, the driving member 230 includes a gear 231, a rack 232 and a driving motor 233, the rack 232 is located on one side of the slide rail 210 and fixed on the carrier frame 240, the gear 231 is rotatably connected to both sides of the beam 220 through a rotating shaft, and the gear 231 is meshed on the rack 232, the driving end of the driving motor 233 is connected to one side of the gear 231, and one side of the driving motor 233 is fixed on the beam 220;

[0051] Through the meshing relationship between the gear 231 and the rack 232, the driving motor 233 drives the gear 231 to roll on the rack 232, thereby realizing the sliding action of the beam 220 on the slide rail 210. This structure can provide precise control and realize a smooth pushing process, ensuring that the sliding action of the beam 220 will not cause excessive vibration or swing, so that the pushing component 200 moves according to the predetermined path and speed, which helps to improve the stability and accuracy of the system.

[0052] In this embodiment, Figure 1-Figure 5 As shown, the hook assembly 300 includes a carriage 301 and a pressure rod 302. The carriage 301 is fixed to one side of the crossbeam 220, and the pressure rod 302 is detachably connected near the bottom end of the carriage 301.

[0053] By connecting the pressure rod 302 near the bottom end of the carriage 301, a certain length is reserved at the bottom end of the carriage 301. The reserved length can be the thickness of a sheet. When the bottom of the carriage 301 moves against the sheet, the pressure rod 302 can press on the sheet to ensure that the sheet does not warp during the movement, which helps to maintain the stability of the sheet and prevent irregular movement or displacement caused by warping, thereby affecting the normal feeding of the sheet.

[0054] In this embodiment, Figure 1-Figure 5 As shown, a buffer pad is provided on one side of the bottom end of the drag plate 301. The buffer pad is provided on one side of the bottom end of the drag plate 301 to help convert the rigid contact between the sheet and the drag plate 301 into a flexible contact, which can effectively reduce the impact force generated during the movement, and the impact force may cause damage to the surface of the sheet. By using the buffer pad, the impact force can be reduced. At the same time, the presence of the buffer pad can prevent scratches or damage to the surface of the sheet. In traditional rigid contact, scratches are easily generated on the surface of the sheet due to the direct contact of hard materials. By using the buffer pad, the contact mode is converted into a flexible contact, which helps to avoid such damage and improves the quality and appearance of the sheet.

[0055] In this embodiment, Figure 1-Figure 5 As shown, the lifting assembly 100 includes a lifter (a lifter driven by a hydraulic cylinder is a common vertical motion device, which realizes the rising and lowering of the lifting platform through the operation of the hydraulic cylinder. This is a prior art and will not be described in detail. The lifter mentioned below will be explained as above).

[0056] The specific working process of the utility model is as follows:

[0057] (1) Preparation before feeding

[0058] First, a stack of sheets is placed on the lifter so that the highest level of the sheets on the lifter is flush with the level of the bottom of the pressing rod 302 .

[0059] (2) Feeding

[0060] After preparation is completed, the driving motor 233 drives the gear 231 to roll on the rack 232, thereby realizing the sliding action of the beam 220 on the slide rail 210. Since the plate on the lifter is flush with the horizontal height of the bottom of the pressure rod 302, the drag plate 301 can effectively support the side wall of the plate, and the pressure rod 302 presses on the plate, and then the beam 220 drives the drag plate 301 and the plate to slide along the path of the slide rail 210.

[0061] (3) Continuous feeding

[0062] When the carriage 301 drags a sheet material below to move, there is a gap of the thickness of the sheet material between the carriage 301 and the sheet material on the lifter of the lifting assembly 100. At this time, the light axis emitted by the transmitting end of the photoelectric sensor 402 is received by its receiving end, so that normal signal transmission is completed between them, and then the situation that there is no sheet material is detected, that is, the receiving end of the photoelectric sensor 402 responds and provides the signal to the lifter of the lifting assembly 100;

[0063] Once the photoelectric sensor 402 fails to detect the presence of the sheet material, the lifter is triggered and responds by driving the sheet material on the lifter to rise by the thickness of the sheet material. This process fills the gap between the slide 301 and the sheet material on the lifting assembly 100, allowing the sheet material on the lifter to continue to be located on one side of the slide 301, thereby ensuring that it can continue to be dragged and displaced by the slide 301.

[0064] Example 2

[0065] Compared with Example 1, the pushing assembly 200 of this embodiment includes a beam 220, a linear module, and two support frames 240 that are arranged in mirror symmetry with each other. The beam 220 is arranged on the moving end of the linear module (the linear module is not shown in the drawings), and the slider on the linear module drives the beam 220 and the drag plate 301 on the beam 220 to move.

[0066] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
