Description

Technical Field

[0001] This application relates to the field of equipment for preparing decorative paper, and in particular to equipment and process for preparing antistatic decorative paper. Background Technology

[0002] In indoor spaces containing electronic devices, antistatic capability is an important indicator, because if electronic devices are interfered with by static electricity during operation, it may cause program malfunctions or even damage to the devices. Therefore, antistatic decorative paper is usually covered and pasted on walls and tabletops to prevent the generation of static electricity.

[0003] Antistatic decorative paper is made by coating an antistatic layer onto a paper base using a coating machine. After the antistatic layer is applied, the paper base is dried in a drying oven, then transported to a slitting machine for slitting, packaging, and storage.

[0004] A typical slitting machine usually consists of multiple conveyor rollers for tensioning and transporting decorative paper, a feeding rack for rotating and supporting the unslit roll of wallpaper, two cutting rollers, and an output roller for mounting the core. One of the cutting rollers is equipped with multiple circular blades as needed, which are installed at the required distances along the axis of the cutting roller. The other cutting roller is equipped with a corresponding pad, which has grooves that mate with the circular blades. During operation, the cutting edge of the circular blade is located in the groove, and the entire roll of decorative paper passes between the two cutting rollers. The circular blades, in conjunction with the pad, cut the decorative paper.

[0005] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: the positions of the circular blades and bushings on the cutter rollers of existing slitting machines are fixed or require manual adjustment. When changing the cutting size, the cutter rollers need to be removed and replaced with suitable cutter rollers, or the positions of the circular blades and bushings on the slitting machine need to be manually adjusted, making the overall adjustment quite troublesome. Summary of the Invention

[0006] To address the problem of cumbersome adjustment of the circular blade position in traditional antistatic decorative paper slitting machines, this application provides an antistatic decorative paper preparation device and process.

[0007] Firstly, the equipment for preparing antistatic decorative paper provided in this application adopts the following technical solution: An apparatus for preparing antistatic decorative paper includes a frame, a transfer roller mounted on the frame, two blade rollers mounted on the frame, blade holders and pads mounted on the two blade rollers respectively, a circular blade mounted on the blade holder, and an adjustment device mounted on the frame. The adjustment device includes an adjustment rod mounted on the frame, a fixing mechanism slidably mounted on the adjustment rod, and a connecting mechanism mounted on the fixing mechanism. The blade holder and the pad are each provided with a fixing component for fixing to the blade roller. The fixing mechanism is used to drive the fixing component to fix the blade holder and the pad to the blade roller. The connecting mechanism is used to drive the blade holder and the pad to slide synchronously with the fixing mechanism.

[0008] With the above technical solution, when it is necessary to adjust the tool holder and the pad, the tool holder and the pad are connected to the fixing mechanism through the connecting mechanism. Then, the tool holder and the pad are slid to the designated position by moving the fixing mechanism. Finally, the fixing mechanism drives the fixing component to fix the tool holder and the pad on the cutter roller to complete the fixing of the tool holder and the pad, making the adjustment of the tool holder and the pad more convenient.

[0009] Optionally, a fixing groove is formed on the cutter roller along its length direction. The fixing assembly includes fixing blocks provided on both the cutter holder and the pad. The fixing blocks are slidably installed in the fixing groove. Fixing bolts are threaded on both the cutter holder and the pad. One end of the fixing bolt is inserted into the fixing block. The fixing block is provided with a clamping block. When the fixing bolt is tightened, the clamping block pushes out and abuts against the side wall of the fixing groove.

[0010] Optionally, a base rod is provided at one end of the fixing groove, and several abutting plates are provided circumferentially around the axis of the abutting rod sidewall. The abutting plates are connected to the base rod by an elastic element. A fixing hole is provided through the fixing block, and a guide block is provided on the abutting plate for cooperating with the fixing hole to retract the abutting plate. When the cutter holder or the pad slides to one end of the cutter roller, the abutting rod and the base rod pass through the fixing hole, and at this time the abutting plate pushes the abutting block to press against the sidewall of the fixing groove.

[0011] Optionally, the fixing mechanism includes a mounting block slidably mounted on the adjusting rod, a tightening motor mounted on the mounting block, and a tightening assembly mounted on the mounting block. The tightening assembly includes two screwdriver heads threaded onto the mounting block for tightening the fixing bolts of the cutter holder and the washer. The screwdriver heads are connected to the tightening motor via a transmission connection. Both ends of the adjusting rod are slidably mounted on the frame along the direction of the screwdriver heads toward or away from the cutter roller.

[0012] Optionally, the connecting mechanism includes a positioning component and a connecting component. The positioning component is used to position the screwdriver head and the fixing bolt, and the connecting component is used to connect the tool holder, the washer, and the mounting block.

[0013] Optionally, a rubber layer is laid on the inner sidewall of the fixing groove, and the clamping block abuts against the rubber layer.

[0014] Through the above technical solution, the rubber layer is used to increase the friction between the rubber layer and the clamping block, improve the stability of the clamping block, and at the same time, the rubber layer is also used to prevent the fixing bolts from loosening. The rubber layer can also make up for the length tolerance of the fixing bolts, so that even if the number of rotations of the screwdriver head is fixed, each fixing bolt can be rotated a fixed number of times to push out the clamping block, and the fixing block can be stably fixed in the fixing groove.

[0015] Optionally, the two cutter rollers are driven by the same motor. The positioning assembly includes a pressure rod slidably mounted on the mounting block, a start button on the mounting block, and a push spring. The start button is used to start the motor that drives the cutter rollers to rotate. One end of the pressure rod is slidably engaged with the fixing groove. When the adjusting block slides close to the cutter roller, the pressure rod presses against the side wall of the cutter roller and presses the start button. When the cutter roller rotates to the point where the pressure rod is opposite to the fixing groove, the push spring pushes the pressure rod into the fixing groove, and at this time the pressure rod releases the start button.

[0016] Optionally, the connecting assembly includes four baffles. When the pressure rod abuts against the cutter roller, the four baffles respectively fit against the end faces of the cutter holder and the pad to limit the position of the cutter holder and the pad.

[0017] Optionally, the pressure rod is provided with a connecting rod, and both the pressure rod and the connecting rod are provided with limiting tubes. A connecting block is slidably installed on the mounting block, and the pressure rod is installed on the connecting block. The diameter of the limiting tube is smaller than the inner diameter of the fixing hole. When the mounting block drives the knife holder and the pad to slide to the base rod, the connecting block is used to drive the limiting tube to pass through the fixing hole and face the guide block. At this time, the guide block is used to cooperate with the limiting tube to retract the clamping plate and pass through the limiting tube. At each of the two apex points of one end of the pressure rod, rollers are rotatably installed to assist one end of the pressure rod in sliding into the fixed groove.

[0018] Secondly, this application provides a process for preparing antistatic decorative paper, comprising the following steps: S1, for preparing antistatic coatings; S2, assemble the paper base onto the coating machine and fill the coating machine with coating material; S3, start the coating machine to apply the antistatic coating to the paper base and then dry and shape it; S4, transport the formed roll of antistatic decorative paper to the slitting machine for slitting; S5, Pack and store the cut paper rolls; The slitting machine in S4 mentioned above is the same as the slitting machine described above.

[0019] In summary, the blade holder and bushing in this application are driven by a baffle via a mounting block, which in turn is driven by a motor screw. This makes adjusting the blade holder and bushing convenient and quick. Furthermore, the cooperation between the fixing bolts, the clamping block, and the rubber layer ensures that the blade holder and bushing are stably fixed to the blade roller. The rubber layer compensates for differences in length and thread count between the fixing bolts, ensuring that each fixing bolt, when rotated the same number of times, pushes the clamping block to clamp the rubber layer with a standard clamping force. Since the axial force of the blade roller on the bushing or blade holder is borne by the cooperation between the fixing block and the fixing groove, there is no relative rotation between the blade holder and the blade roller during cutting, resulting in a more stable cutting effect.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0031] In a first aspect, embodiments of this application disclose an apparatus for preparing antistatic decorative paper, referring to... Figure 1 and Figure 2 It includes a frame 1, a transport roller rotatably mounted on the frame 1, two cutter rollers 6 rotatably mounted on the frame 1, and several cutter holders 12 and pads 13 slidably mounted on the cutter rollers 6. The cutter holders 12 are used to mount circular cutters 14.

[0032] An adjustment device 2 is provided on the frame 1 for adjusting the position of the tool holder 12 and the pad 13. A fixing component 5 is provided on both the tool holder 12 and the pad 13 for fixing themselves. At the same time, the adjustment device 2 is also used to activate the fixing component 5 to fix the tool holder 12 or the pad 13.

[0033] Reference Figure 7 and Figure 8 The fixing component 5 includes a fixing block 51 integrally mounted on the cutter holder 12 or the pad 13, two abutting blocks 53, and a fixing bolt 52. A fixing groove 61 is formed on the side wall of the cutter roller 6 along its length, and the fixing block 51 is slidably installed in the fixing groove 61. A mounting hole 512 is formed through the fixing block 51 along the width of the fixing groove 61, and the two abutting blocks 53 are slidably installed in the mounting hole 512.

[0034] Reference Figure 7 and Figure 8The fixing bolt 52 is threaded onto the tool holder 12 or the pad 13, and one end of the fixing bolt 52 passes through the tool holder 12 or the pad 13 and is located in the mounting hole 512. The two clamping blocks 53 are provided with guide slopes 10 on their opposite sides. One end of the fixing bolt 52 is provided with a chamfer. After tightening the fixing bolt 52, the fixing bolt 52 pushes the clamping block 53 against the side wall of the fixing groove 61 through the cooperation of the chamfer and the guide slope 10 to fix the fixing block 51.

[0035] Reference Figure 4 and Figure 5 A rubber layer 8 is laid on the side wall of the fixing groove 61. The clamping block 53 abuts against the rubber layer 8. The rubber layer 8 increases the friction received by the clamping block 53, thereby improving the stability of the fixing block 51. Furthermore, after the fixing bolt 52 is tightened, the rubber layer 8, while counteracting loosening of the fixing bolt 52, can compensate for the length error of the fixing bolt 52. That is, the number of tightening turns is calculated based on the length of the shortest fixing bolt 52 within the tolerance range. The extra distance that the clamping block 53 moves due to the longer fixing bolt 52 is accommodated by the rubber layer 8. This ensures that all fixing bolts 52, after rotating the same number of turns, have sufficient clamping force after pushing the clamping block 53 against the rubber layer 8. Reference Figure 4 and Figure 5 A base rod 62 is fixedly installed at one end face of the fixing groove 61. Two clamping plates 63 are provided circumferentially on the base rod 62. The clamping plates 63 are slidably installed on the base rod 62 along the radial direction. An elastic element 64 is provided between the clamping plate 63 and the base rod 62. The elastic element 64 is set as a spring. Under normal conditions, the clamping rod protrudes from the base rod 62 under the action of the spring. A fixing hole 511 is provided through the fixing block 51. The fixing hole 511 passes through the mounting hole 512. The base rod 62 and the clamping plate 63 can pass through the fixing hole 511. At this time, the spring pushes the clamping plate 63 to push the clamping block 53 out and clamp the rubber layer 8 to fix the knife holder 12 or the pad 13.

[0036] Reference Figure 4 and Figure 5 A guide block 65 is integrally provided on one end of the abutment plate 63. The guide block 65 is provided with a guide slope 10. When the base rod 62 and the abutment plate 63 slide through the fixing hole 511, the abutment plate 63 is pushed to close by the cooperation between the guide block 65 and the opening of the fixing hole 511. When the guide block 65 passes out of the fixing hole 511 and the abutment plate 63 opens to push the abutment block 53 to press against the rubber layer 8, one end face of the guide block 65 is attached to the side wall of the fixing block 51 to further limit the movement of the fixing block 51.

[0037] Reference Figure 4 and Figure 5Multiple cutter holders 12 and corresponding multiple pads 13 are usually provided on the cutter roller 6 for convenient use when needed. The excess pads 13 and cutter holders 12 are slid to one end of the cutter roller 6 for storage, and then the excess cutter holders 12 and pads 13 are fixed by the base rod 62 and the clamping rod.

[0038] Reference Figure 2 and Figure 3 The adjusting device 2 includes an adjusting rod 21, a fixing mechanism 3, and a connecting mechanism 4. The adjusting rod 21 is slidably mounted on the frame 1 in a direction close to or away from the cutter roller 6, and the adjusting rod 21 is parallel to the cutter roller 6. The adjusting rod 21 is driven by a motor lead screw. The fixing mechanism 3 includes a mounting block 31 slidably mounted on the adjusting rod 21, a tightening motor 32 fixedly mounted on the mounting block 31, and a tightening assembly 33 provided on the mounting block 31. The mounting block 31 is also driven by a motor lead screw.

[0039] Reference Figure 6 and Figure 7 The tightening assembly 33 includes two screwdriver heads 331 threaded onto the mounting block 31 for tightening the fixing bolts 52 on the tool holder 12 and the fixing bolts 52 on the washer 13, respectively. The screwdriver heads 331 are connected to the tightening motor 32 via gear transmission. A columnar gear is coaxially mounted on the main shaft of the tightening motor 32 to ensure that the screwdriver heads 331 can also be connected to the tightening motor 32 for transmission when moving.

[0040] Reference Figure 6 and Figure 7 When the mounting block 31 moves to the position where the screwdriver head 331 aligns with the fixing bolt 52 on the tool holder 12 and the washer 13, the adjusting rod 21 slides towards the tool roller 6, causing one end of the screwdriver head 331 to insert into the internal hexagonal socket of the fixing bolt 52. The tightening motor 32 starts, driving the screwdriver head 331 to rotate and tighten the fixing bolt 52. After the fixing bolt 52 is tightened by rotating a specified number of times, the adjusting rod 21 retracts, pulling the screwdriver head 331 out of the internal hexagonal socket.

[0041] Since each fixing bolt 52 only needs to be tightened the same number of turns to secure the fixing block 51, the alignment of the screwdriver head 331 and the fixing bolt 52 is relatively precise and less prone to misalignment. Furthermore, the program design is relatively simple; it only requires setting the number of rotations to be completed before retracting.

[0042] Reference Figure 4 and Figure 7The connecting mechanism 4 is mounted on the mounting block 31. The connecting mechanism 4 includes a positioning assembly 41 for positioning and fixing the bolt 52, and a connecting assembly 42 for connecting the mounting block 31, the cutter holder 12, and the gasket 13. The positioning assembly 41 includes a connecting block 411 slidably mounted on the mounting block 31 and a pressure rod 412 slidably mounted on the connecting block 411. A thrust spring 414 is provided between the pressure rod 412 and the connecting block 411, with both ends of the thrust spring 414 fixedly connected to the pressure rod 412 and the connecting block 411, respectively. A start button 413 for starting the cutter roller 6 motor is also fixedly mounted on the connecting block 411. The connecting block 411 is driven by a motor lead screw.

[0043] Reference Figure 4 and Figure 7 The two cutter rollers 6 are driven by the same motor. One end of the pressure rod 412 is in sliding engagement with the fixing groove 61, and a pressure plate 415 is fixedly installed on the pressure rod 412. When the adjusting rod 21 slides to the point where the screwdriver head 331 is close to the fixing bolt 52, one end of the pressure rod 412 presses against the cutter roller 6, and at this time the pressure plate 415 on the pressure rod 412 presses down the start button 413, the motor of the cutter roller 6 starts and drives the cutter roller 6 to rotate. When the cutter roller 6 rotates to the point where the fixing groove 61 is opposite to the pressure rod 412, the push spring 414 pushes the pressure rod 412 to slide into the fixing groove 61, the pressure plate 415 releases the start button 413, the drive motor of the cutter roller 6 stops, the cutter roller 6 stops rotating under the limit of the pressure rod 412, and at this time the fixing bolt 52 and the screwdriver head 331 are directly opposite each other.

[0044] Meanwhile, rollers 9 are rotatably installed at the two apex points of one end of the pressure rod 412 to reduce the friction between the pressure rod 412 and the rubber layer 8 when the pressure rod 412 slides into the fixed groove 61 to correct the cutter roller 6, thereby reducing the possibility of the pressure rod 412 getting stuck when inserted.

[0045] Reference Figure 6 and Figure 7 A connecting rod 7 is integrally provided on the pressure rod 412. When one end of the pressure rod 412 slides into the fixing groove 61 of the cutter roller 6, the other end of the connecting rod 7 enters the fixing groove 61 of another cutter roller 6.

[0046] Reference Figure 6 and Figure 7A limiting tube 71 is fixedly installed on one end of the connecting rod 7 and the pressure rod 412 within the fixing groove 61. The limiting tube 71 corresponds to the fixing hole 511, and the diameter of the limiting tube 71 is smaller than the diameter of the fixing hole 511. The sliding direction of the connecting block 411 is parallel to the length direction of the cutter roller 6. When the mounting block 31 moves to the storage area and needs to take out the stored cutter holder 12 and the pad 13, after the fixing groove 61 is positioned by the pressure rod 412, the connecting block 411 is moved to drive the limiting tube 71 to be inserted into the fixing hole 511. During the insertion process, the limiting tube 71 will drive the abutment plate 63 to retract through the guide block 65, thereby causing the abutment block 53 to loosen the rubber layer 8, reducing the frictional resistance generated when moving the cutter holder 12 and the pad 13, and reducing the wear of the rubber layer 8.

[0047] Reference Figure 6 and Figure 7 The connecting assembly 42 includes a baffle 421 mounted on the mounting block 31. When the adjusting rod 21 moves to a position close to the cutter roller 6, the cutter holder 12 is inserted between two baffles 421, and the pad 13 is inserted between two other baffles 421. The end faces of the cutter holder 12 and the pad 13 are both in contact with the baffle 421. When the mounting block 31 slides, the baffle 421 drives the cutter holder 12 and the pad 13 to slide.

[0048] The implementation principle of the antistatic decorative paper preparation equipment in this application embodiment is as follows: When it is necessary to add knife holders 12 and pads 13, the motor screw drives the mounting block 31 to slide to the first knife holder 12 and pad 13 aligned with the base rod 62. Then, the motor screw drives the adjusting rod 21 to slide towards the knife roller 6, so that the baffle 421 is in contact with the two end faces of the knife holder 12 and the pad 13 respectively. At this time, the knife roller 6 presses down the pressure rod 412. The pressure rod 412 presses down the start button 413 through the pressure plate 415. The start button 413 starts the drive of the two knife rollers 6. The motor drives the two cutter rollers 6 to rotate until one end of the pressure rod 412 slides into the fixed groove 61. At this time, the baffle 421 releases the start button 413, the drive motor of the cutter roller 6 stops, and the pressure rod 412 slides smoothly into the fixed groove 61 under the drive of the roller 9. While calibrating the position of the fixed groove 61 through the pressure rod 412, the cutter roller 6 is limited and fixed through the cooperation between the pressure rod 412 and the fixed groove 61. Since the two cutter rollers are driven by the same motor, the two cutter rollers are connected by transmission. When one cutter roller is positioned, the other cutter roller is also positioned.

[0049] Then, the motor screw drives the connecting block 411 to move, causing the limiting tube 71 on the pressure rod 412 and connecting rod 7 to be inserted into the fixing hole 511, and the screwdriver head 331 to be inserted into the internal hexagonal hole of the fixing bolt 52. The limiting tube 71 pushes the two abutting plates 63 to retract through the guide block 65, thereby causing the abutting block 53 that abuts the rubber layer 8 to loosen under the push of the abutting plate 63, causing the fixing block 51 to disengage from the fixed state, and then the mounting block 31 slides through. After the baffle 421 moves the tool holder 12 and the pad 13 to the designated position, it stops. After the connecting block 411 moves in the opposite direction to pull out the limit tube 71, the tightening motor 32 starts and drives the screwdriver head 331 to rotate and tighten the fixing bolt 52. The fixing bolt 52 pushes the pressing block 53 to press against the inner wall of the fixing groove 61 to complete the fixing of the fixing block 51 and the tool holder 12 or the pad 13. Then the adjusting rod 21 returns to its original position, and finally the mounting block 31 returns to one end of the adjusting rod 21.

[0050] When the excess cutter holder 12 and pad 13 are sent back to one end of the cutter roller 6 for storage, the fixing bolt 52 is loosened in the manner described above, and then the limiting tube 71 is inserted into the fixing hole 511 and driven to the base rod 62. Then the limiting tube 71 is pulled out, so that the abutting plate 63 on the base rod 62 pushes the abutting block 53 to abut the rubber layer 8 to complete the fixing.
