Description

TECHNICAL FIELD

[0001] The present application relates to the field of artificial leather production equipment, in particular to a embossing machine and artificial leather embossing equipment. BACKGROUND

[0002] PVC artificial leather is a kind of artificial leather produced by using resin as raw material, which has been widely used in shoes, clothes, bags, furniture decoration and automotive interior due to its excellent physical properties and cost advantage. In the production process of PVC artificial leather, embossing machine is needed to emboss the PVC artificial leather, and the designed pattern is printed on the surface of the PVC artificial leather to achieve an aesthetic effect.

[0003] The traditional embossing machine usually adopts a rubber roller supported by a frame and a cooperating structure with an embossing roller, and the embossing roller and the rubber roller are arranged in parallel. The outer circumferential surface of the embossing roller is pre-engraved with decorative patterns. During embossing operation, the artificial leather passes between the embossing roller and the rubber roller, and the rubber surface of the artificial leather abuts against the embossing roller. The decorative patterns are transferred to the surface of the artificial leather by the pressure between the two rollers, so as to form the required patterns on the surface of the artificial leather.

[0004] In the prior art, pneumatic driving mechanisms are usually arranged at both ends of the embossing roller in the axial direction. The reciprocating motion of the air cylinder drives the embossing roller to make compression displacement adjustment along the slide rail. This pneumatic driving method has the advantages of fast response and convenient maintenance when shallow embossing (such as 0.1mm level pattern depth) is performed. However, as the market demand for three-dimensional patterns increases, when 1mm level deep patterns need to be embossed, the pneumatic system exposes significant technical defects. First, the compressibility of compressed air leads to pressure fluctuation during the pressure maintaining stage, making it difficult to maintain stable contact pressure. Second, the maximum output pressure of the pneumatic system is limited by the supply pressure of 0.6-0.8MPa. When the contact area of the embossing roller increases, the system cannot break through the pressure bottleneck and provide the high linear pressure required for deep embossing. These technical limitations directly lead to quality problems such as pattern rebound and insufficient shaping of deep embossed products, which seriously affect the development of high value-added products. SUMMARY

[0005] In order to stably realize the production of deep embossed artificial leather, the present application provides an embossing machine and artificial leather embossing equipment.

[0006] The embossing machine provided by the present application adopts the following technical scheme: an embossing machine, comprising a frame, a support roller and an embossing roller are rotatably connected to the frame, the embossing roller is arranged on the frame in a radial sliding manner through a bearing seat at both ends of the embossing roller, an embossing oil cylinder is fixedly connected to the frame at both ends of the embossing roller, the embossing oil cylinder is arranged along the sliding direction of the embossing roller, the piston rod of the embossing oil cylinder is connected with the bearing seat, a mounting bracket for mounting the embossing oil cylinder is arranged on the frame, and the bearing seat is arranged in a sliding manner on the mounting bracket.

[0007] By adopting the above technical scheme, the piston rod of the embossing oil cylinder is connected with the bearing seat, the position of the embossing roller relative to the supporting roller can be accurately controlled, and stable pressing force is provided. And through the driving of the embossing oil cylinder, the embossing roller can exert greater pressure on the artificial leather during the working process, thereby effectively solving the problem of being unable to press deep lines, and ensuring that the embossing machine can clearly and stably press out deep lines.

[0008] Preferably, the mounting frame is slidably arranged on the rack along the length direction of the embossing roller, and the rack is provided with a displacement device for driving the mounting frame to slide and fix.

[0009] By adopting the above technical scheme, when it is necessary to dismount and replace the embossing roller, the mounting frame can be slid along the length direction of the embossing roller, thereby expanding the operation space, facilitating the taking out of the embossing roller from the mounting frame, and improving the convenience of equipment maintenance and replacement.

[0010] Preferably, the displacement device comprises a driving frame slidably arranged on the rack, driving plates are arranged on both sides of the driving frame, guide grooves are arranged on the driving plates, guide surfaces are arranged on the inner walls of the guide grooves, and driving rods are fixed to the bottoms of the mounting frames and can slide along the length direction of the guide surfaces in the guide grooves.

[0011] By adopting the above technical scheme, the guide grooves are arranged along the sliding direction of the driving frame, and can be designed in a bent shape according to actual needs. This design enables the driving rods to slide along the guide surfaces on the inner walls of the guide grooves, thereby stably driving the mounting frames to slide or reset relative to the rack.

[0012] Preferably, support rods are arranged on the driving frame at both ends of the embossing roller, abutting members capable of abutting with the rotating shafts of the embossing rollers are arranged on the top portions of the support rods, the abutting members are slidably arranged on the support rods in the vertical direction, the support rods are slidably arranged on the driving frame, and baffles are arranged on the mounting frames. When the mounting frame starts to slide to the outside of the rack, the baffle is located in front of the support rod. When the baffle moves to the outside of the support rod, the support rod can move with the driving frame. The rack is provided with a lifting mechanism for receiving the embossing roller on the support rod away from one end of the supporting roller. When the embossing roller moves to above the lifting mechanism with the support rod, the support rod slides downward, and the embossing roller falls into the lifting mechanism.

[0013] By adopting the technical scheme, the abutting piece at the top of the support rod abuts against the rotating shaft of the embossing roller, and the embossing roller can be stably supported; when the driving frame moves, the support rod first abuts against the baffle, and at this time, the mounting frame has not completely moved to the outside of the rack, and when the mounting frame moves out to make room, the baffle moves away from the front end of the support rod, and the support rod continues to move with the driving frame, so that the embossing roller is stably carried to the upper side of the lifting mechanism. Then, when the embossing roller moves to the upper side of the lifting mechanism, the support rod moves downward, so that the embossing roller accurately falls into the lifting mechanism, the reliable transfer and receiving of the embossing roller are realized, and the operation convenience and safety of the equipment are improved.

[0014] Preferably, the top of the support rod is provided with a support plate, the abutting piece comprises a support block slidingly arranged at the top of the support plate, the top surface of the support block is provided with a notch matched with the rotating shaft of the embossing roller, and the bottom surface of the support block is connected with an adjusting screw threadedly connected with the support plate.

[0015] By adopting the technical scheme, the support plate is arranged at the top of the support rod, the support block is slidingly arranged on the support plate and matched with the rotating shaft of the embossing roller, and the height of the support block can be adjusted through the threaded connection between the adjusting screw and the support plate. During the working of the embossing machine, the support block can be lowered below the embossing roller, so that the support block does not affect the embossing process, and the stable operation of the embossing roller is ensured.

[0016] Preferably, the driving frame is slidingly connected with a support seat, the support rod is slidingly arranged on the support seat, the side surface of the support rod is provided with a control rod, the rack is provided with a first horizontal groove, a vertical groove, a second horizontal groove and a first inclined groove for sliding of the control rod, the first horizontal groove, the vertical groove, the second horizontal groove and the first inclined groove are sequentially communicated, the first inclined groove is provided with a first one-way control piece at the communication position with the first horizontal groove, and the first one-way control piece is used to limit the control rod to only enter the first horizontal groove from the first inclined groove.

[0017] By adopting the technical scheme, the support seat is arranged, so that the horizontal sliding and vertical sliding of the support rod on the driving frame can be realized. When the driving frame starts to slide, the mounting frame first moves to the outside of the rack, and the support seat slides horizontally on the driving frame due to the blocking of the baffle, and at this time, the support seat is stationary relative to the rack. When the mounting frame completely slides to the outside of the rack, the baffle moves with the mounting frame and no longer blocks the support seat, and the support seat immediately continues to slide with the driving frame until reaching the upper side of the lifting mechanism, the control rod falls into the vertical groove from the first horizontal groove, and the embossing roller on the abutting piece is transferred to the lifting mechanism. In this way, only one driving frame can drive the mounting frame and the support rod to move, the driving structure is simplified, and the cost of the equipment is reduced.

[0018] Preferably, the lifting mechanism comprises a lifting frame arranged to slide in the vertical direction on the frame, and a supporting portion is arranged on the top of the lifting frame to support the rotating shaft of the embossing roller at both ends, and a driving member is arranged on the frame to drive the lifting frame to slide, and when the control rod is slid to the first horizontal groove away from one end of the embossing roller, the driving member drives the supporting portion to slide above the abutting member.

[0019] By adopting the above technical scheme, when the embossing roller needs to be replaced or maintained, the control rod is slid to the first horizontal groove away from one end of the embossing roller, and the abutting member is accurately moved above the supporting portion, so that the embossing roller can be smoothly lowered onto the supporting portion, and the lifting mechanism can stably support the rotating shaft of the embossing roller. At the same time, the arrangement of the driving member realizes the stable lifting of the lifting frame, effectively improves the automation degree of the embossing roller loading and unloading process, and reduces the strength of manual operation.

[0020] Preferably, the driving member comprises an intermediate gear rotatably arranged on the frame, and a driving rack is fixedly connected to the driving frame, and a driven rack is arranged on the lifting frame, and the driving rack and the driven rack are drivingly connected through the intermediate gear.

[0021] By adopting the above technical scheme, the meshing relationship between the intermediate gear and the driving rack and the driven rack is utilized to realize the linkage between the driving frame and the lifting frame. When the driving frame moves, the driving rack drives the intermediate gear to rotate, thereby driving the driven rack meshing with the intermediate gear to move, so that the lifting frame slides in the vertical direction. This structure can ensure that the lifting mechanism can act synchronously during the replacement or installation of the embossing roller, improve the operation efficiency and ensure the stability.

[0022] Preferably, a second inclined groove is arranged on the frame, and the two ends of the second inclined groove are respectively communicated with the first horizontal groove and the second horizontal groove, and a guide member is arranged in the second horizontal groove, and when the control rod in the second horizontal groove slides towards the lifting device, the control rod enters the second inclined groove under the guidance of the guide member, and a second one-way control member is arranged at the position where the second inclined groove is communicated with the first horizontal groove, and the second one-way control member is used to limit the control rod to only enter the first horizontal groove from the second inclined groove.

[0023] By adopting the above technical scheme, the arrangement of the second inclined groove can realize the automatic feeding of the embossing roller. During operation, the embossing roller to be installed is first placed on the supporting portion, and then the driving frame drives the supporting rod to slide from the second horizontal groove towards the lifting mechanism. In this process, the control rod smoothly enters the second inclined groove under the guidance of the guide member, and finally returns to the first horizontal groove. At this time, the supporting block accurately lifts the embossing roller on the lifting device to complete the position adjustment. Subsequently, the driving member is reset, and the control rod slides in the first horizontal groove, so that the embossing roller is accurately conveyed to the vicinity of the bearing seat, thereby greatly improving the feeding efficiency and operation convenience.

[0024] The artificial leather embossing device using the embossing machine comprises unwinding devices, tension control devices, embossing machines and finished product winding devices arranged on the ground in sequence, the embossing machine is arranged on the ground in sliding mode along a direction perpendicular to the material conveying direction, and a fixing mechanism is arranged for fixing the embossing machine.

[0025] By adopting the technical scheme, the embossing machine is cooperated with the unwinding devices, the tension control devices and the finished product winding devices, the continuity and efficiency of the whole production process are effectively improved, and the material waste and the production interruption risk caused by improper fixing position of the equipment are reduced. In addition, the embossing machine can be arranged on the ground in sliding mode along a direction perpendicular to the material conveying direction, so that the embossing machine can be slid out of the embossing device in the lateral direction. This design not only facilitates the disassembly and installation of the embossing roller by the operator, but also effectively improves the convenience of equipment maintenance. In combination with the use of the fixing mechanism, the stability of the position of the embossing machine can be ensured when the embossing machine works, so that the accuracy and consistency of the embossing effect are ensured.

[0026] In summary, the present application has at least one of the following beneficial technical effects:

[0027] The setting of the embossing oil cylinder replaces the traditional pneumatic driving mode, can provide stable and adjustable high pressure output, effectively overcomes the pressure fluctuation problem caused by the compressibility of compressed air, and ensures that the lines are clear and the shaping degree is high during deep embossing processing.

[0028] The cooperation of the supporting rod and the lifting mechanism makes the installation and replacement of the embossing roller more convenient, optimizes the operation process of the equipment, and improves the production efficiency and the convenience of equipment maintenance.

DETAILED DESCRIPTION

[0039] The following will be described in detail in combination with the accompanying drawings. Figures 1-9 The present application will be further described in detail.

[0040] Embodiment 1

[0041] The embodiments of the present application disclose an embossing machine. Referring to Figure 1 , Figure 2 and Figure 5The embossing machine 1 comprises a rack 11, a supporting roller 12 is rotatably connected to the rack 11, the supporting roller 12 is arranged along the width direction of the rack 11, and a mounting rack 13 is arranged behind the supporting roller 12 on the rack 11. The mounting rack 13 is provided with an embossing roller 131 arranged in parallel to the supporting roller 12. The embossing roller 131 is connected with the mounting rack 13 through a bearing seat 133. The bearing seat 133 is detachably connected with the rotating shaft of the embossing roller 131 through bolts. The bearing seat 133 is arranged on the mounting rack 13 in a sliding manner along the radial direction of the supporting roller 12. The mounting rack 13 is further provided with an embossing oil cylinder 132. The piston rod of the embossing oil cylinder 132 is arranged in parallel to the sliding direction of the bearing seat 133. The piston rod of the embossing oil cylinder 132 is fixedly connected with the bearing seat 133.

[0042] The embossing oil cylinder 132 is powered by a hydraulic station fixed on the rack 11. During the embossing operation, the artificial leather passes between the embossing roller 131 and the supporting roller 12. The embossing oil cylinder 132 drives the embossing roller 131 to slide towards the artificial leather and abut against the artificial leather. Then, the embossing roller 131 and the supporting roller 12 rotate to perform the embossing treatment on the surface of the artificial leather. The embossing oil cylinder 132 replaces the traditional pneumatic system, which solves the problems of pressure fluctuation and insufficient output during deep embossing. The high-pressure characteristics of the hydraulic system enable the embossing oil cylinder 132 to provide stable linear pressure, thereby ensuring that the contact pressure between the embossing roller 131 and the supporting roller 12 is uniformly distributed, and the product quality is ensured.

[0043] With reference to Figure 1 Since the surface decoration pattern design of the artificial leather is various, the embossing roller 131 needs to be frequently replaced during actual production. In order to facilitate the disassembly of the embossing roller 131 from the embossing machine, the mounting rack 13 slides along the length direction of the embossing roller 131. A guide rail 111 is fixedly connected to the rack 11. A sliding groove matched with the guide rail 111 is arranged on the mounting rack 13. A displacement device 2 for driving the mounting rack 13 to slide and fix is arranged on the rack 11. When it is desired to disassemble the embossing roller 131, the connection between the embossing roller 131 and the bearing seat 133 is first released. Then, the embossing oil cylinder 132 drives the bearing seat 133 to move away from the embossing roller 131. The displacement device 2 drives the entire mounting rack 13 to slide towards the outside of the rack 11. The embossing roller 131 can directly fall between the two mounting racks 13, thereby saving manual disassembly labor.

[0044] With reference to Figure 1 and Figure 3The displacement device 2 comprises a driving frame 21 which is slidably arranged on the rack 11 along the length direction of the rack 11, the driving frame 21 is arranged in a U shape and horizontally placed, two driving plates 22 are fixedly connected to the two sides of the driving frame 21, the driving plates 22 are provided with horizontally arranged guide grooves 221, the guide grooves 221 are arranged along the sliding direction of the driving frame 21, the inner wall of the guide groove 221 is provided with a guide surface 222, the guide surface 222 is arranged in a bending shape and is connected by an inclined surface and a plane, the bottom of the mounting frame 13 is fixedly provided with a driving rod 134, the bottom of the driving rod 134 can slide along the length direction of the guide surface 222 in the guide groove 221. When the driving frame 21 slides, the driving rod 134 slides along the guide surface 222, and drives the two mounting frames 13 to move towards the outside of the rack 11, when the mounting frame 13 slides to the position, the mounting frame 13 can be kept on the outside of the rack 11 even if the driving frame 21 continues to slide under the limiting action of the guide groove 221.

[0045] In order to facilitate the control of the sliding of the driving frame 21, a motor 119 is fixedly connected to the rack 11, a driving screw 118 which is fixed to the output shaft of the motor 119 is rotatably connected to the rack 11, the driving screw 118 is threadedly connected with the driving frame 21, and guide rods 8 are fixedly connected to the rack 11 on the two sides of the driving screw 118, the guide rods 8 are arranged in parallel with the driving screw 118, and the driving frame 21 is slidably connected with the guide rods 8. Only the forward and reverse rotation of the motor 119 needs to be controlled, and the sliding of the driving frame 21 on the rack 11 and the fixing can be realized.

[0046] With reference to Figure 3 Since the manual disassembly of the embossing roller 131 needs to always support the two ends of the embossing roller 131, it is very laborious, and in order to further improve the replacement efficiency of the embossing roller 131, support seats 3 are slidably connected to the driving frame 21 on the two ends of the embossing roller 131, the driving frame 21 is provided with a gap groove 212 for the sliding of the support seat 3, the gap groove 212 is arranged along the sliding direction of the driving frame 21, the bottom of the support seat 3 is slidably arranged in the gap groove 212, the support seat 3 is arranged in a cylindrical shape, a support rod 31 is slidably connected to the support seat 3 along the vertical direction, the top of the support rod 31 is provided with an abutting piece, the abutting piece can slide vertically relative to the support rod 31, and the abutting piece is used for abutting with the rotating shaft of the embossing roller 131.

[0047] With reference to Figure 4To avoid interference with the embossing roller 131 when working, a support plate 312 is fixedly connected to the top of the support rod 31, the support plate 312 is horizontally arranged, the abutting member includes a support block 313, the top surface of the support block 313 is provided with a notch 3131 matched with the rotating shaft of the embossing roller 131 and a stop block, an adjusting screw 32 is fixedly connected to the bottom of the support block 313, the adjusting screw 32 is vertically arranged, an adjusting nut 3121 is rotatably connected to the support plate 312, the adjusting screw 32 cooperates with the adjusting nut 3121, rotating the adjusting nut 3121 can drive the support block 313 to slide up and down. On the bottom of the support block 313, guide rods are fixedly connected to the two sides of the adjusting screw 32, the guide rods are slidingly connected with the support plate 312, and the support block 313 is guided and limited.

[0048] When the embossing roller 131 needs to be disassembled, the embossing cylinder 132 first drives the embossing roller 131 to slide above the support block 313, then the adjusting nut 3121 is rotated, the support block 313 slides upward, when the support block 313 abuts against the rotating shaft of the embossing roller 131, the cover plate of the bearing seat 133 can be disassembled, then the embossing cylinder 132 drives the base of the bearing seat 133 to slide upward, and the bearing seat 133 is separated from the embossing roller 131.

[0049] Referring to Figure 5 To facilitate the removal of the embossing roller 131 from the drive frame 21, a lifting mechanism 4 is arranged on the rack 11 away from the support roller 12. When the rotating shaft of the embossing roller 131 abuts against the support block 313, the motor 119 is started to drive the frame 21 to slide, and the mounting frame 13 slides outwardly away from the rack 11. At this time, to avoid the embossing roller 131 on the support block 313 from colliding with the mounting frame 13, a baffle 135 is arranged on the mounting frame 13 and abuts against the support seat 3. Under the cooperation of the baffle 135 and the gap groove 212, the support seat 3 is temporarily stationary relative to the rack 11. When the mounting frame 13 completely slides to the outside of the rack 11, the baffle 135 also moves out of the front end of the support seat 3. At this time, the drive frame 21 drives the support seat 3 to slide towards the lifting mechanism 4. When the embossing roller 131 moves above the lifting mechanism 4 with the support rod 31, the support rod 31 slides downward, and the embossing roller 131 falls into the lifting mechanism 4.

[0050] Referring to Figure 6To facilitate the reset of the support seat 3, a reset spring 213 is arranged in the displacement slot 212 along the sliding direction of the support seat 3. One end of the reset spring 213 is fixed to the support seat 3, and the other end is fixed to the inner wall of the displacement slot 212. The reset spring 213 drives the support seat 3 to always slide away from the one end of the support roller 12. In addition, the baffle 135 is arranged on the mounting frame 13 along the axis direction of the embossing roller 131. The end of the baffle 135 is chamfered, and the mounting frame 13 is provided with a driving spring that drives the baffle 135 to always slide outward of the mounting frame 13. The baffle 135 is arranged to slide, avoiding interference between the baffle 135 and the support seat 3 when the support seat 3 slides towards the support roller 12, and improving the stability of the equipment.

[0051] With reference to Figure 6 And Figure 7 To facilitate the control of the lifting of the support rod 31, a control rod 311 is fixedly connected to the side of the support rod 31 facing the rack 11. The control rod 311 is arranged perpendicular to the support rod 31. The rack 11 is provided with a first horizontal slot 112, a vertical slot 113, a second horizontal slot 114, and a first inclined slot 115 on the side facing the support rod 31, for the end of the control rod 311 to slide away from the support rod 31. The first horizontal slot 112, the vertical slot 113, the second horizontal slot 114, and the first inclined slot 115 are sequentially connected. In the initial state, the control rod 311 is located at the end of the first horizontal slot 112 away from the vertical slot 113. The position of the vertical slot 113 corresponds to the position of the lifting mechanism 4. When the drive frame 21 drives the support seat 3 to slide above the lifting mechanism 4, the control rod 311 enters the vertical slot 113 under the action of gravity, and the support rod 31 slides downward. The control rod 311 finally falls into the second horizontal slot 114. At this time, the lifting mechanism 4 is located above the support block 313, and the embossing roller 131 on the support block 313 is transferred into the lifting mechanism 4. Then the drive frame 21 drives the support seat 3 to return, and the control rod 311 slides in the second horizontal slot 114 towards the support roller 12, and finally passes through the first inclined slot 115 to return to the starting position in the first horizontal slot 112. At this time, the drive frame 21 is reset to the initial position, and the mounting frame 13 is also reset under the guidance of the guiding surface 222 of the guide slot 221.

[0052] With reference to Figure 7To avoid the control rod 311 from falling into the first inclined groove 115 when passing the junction of the first horizontal groove 112 and the first inclined groove 115, a first one-way control member is arranged at the junction of the first inclined groove 115 and the first horizontal groove 112, which is used to limit the control rod 311 to enter the first horizontal groove 112 only from the first inclined groove 115. The first one-way control member comprises a first switch plate 5 which is rotationally arranged on the rack 11 and located at the junction of the first inclined groove 115 and the first horizontal groove 112. The rotation shaft of the first switch plate 5 is arranged along the length direction of the control rod 311 and located at one end close to the second horizontal groove 114. The first switch plate 5 is flush with the bottom surface of the first horizontal groove 112 when closed. When the control rod 311 wants to enter the first horizontal groove 112 from the first inclined groove 115, the control rod 311 can enter directly after pushing open the first switch plate 5. When the control rod 311 completely enters the first horizontal groove 112, the first switch plate 5 resets to the horizontal state under the action of gravity. When the control rod 311 slides from the first horizontal groove 112 to the vertical groove 113, the control rod 311 directly slides over the first switch plate 5, and the first switch plate 5 cannot be opened. By arranging the first switch plate 5, the control rod 311 can only enter the first horizontal groove 112 from the first inclined groove 115, and cannot enter the first inclined groove 115 from the first horizontal groove 112.

[0053] With reference to Figure 5 The lifting mechanism 4 comprises a lifting frame 41 which is arranged to slide in the vertical direction on the rack 11. The lifting frame 41 is arranged in a U shape. A supporting portion is arranged at the top of the lifting frame 41 and used to support the rotating shafts of the ends of the embossing roller 131. The supporting portion comprises two supporting blocks 411 arranged at the two ends of the lifting frame 41. The supporting blocks 411 are provided with grooves matched with the embossing roller 131. To facilitate driving the lifting mechanism 4 to slide, a driving member is arranged on the rack 11 to drive the lifting frame 41 to slide. When the control rod 311 slides to the end of the first horizontal groove 112 away from the embossing roller 131, the driving member drives the supporting portion to slide to the highest position.

[0054] The driving member comprises intermediate gears 117 rotationally arranged on the rack 11. The intermediate gears 117 are arranged in plurality and meshed with or coaxially connected with each other. A driving rack 211 is fixedly connected to the driving frame 21 and arranged along the sliding direction of the driving frame 21. A driven rack 412 is fixedly connected to the lifting frame 41 and arranged vertically. The driving rack 211 and the driven rack 412 are meshed with the corresponding intermediate gears 117. When the driving frame 21 slides towards the lifting frame 41, the driving rack 211 drives the intermediate gears 117 meshed therewith to rotate, and then the driven rack 412 is driven by the intermediate gears 117 meshed therewith to slide upwards under the transmission action of the intermediate gears 117.

[0055] Referring to Figure 8 When the driving frame 21 slides to the farthest position, the control rod 311 falls into the second horizontal groove 114, the supporting block 411 is located on the same straight line with the support block 313 in the width direction of the rack 11, and the supporting block 411 is located above the support block 313 in the vertical direction, and the embossing roller 131 is transferred from the support block 313 to the supporting block 411.

[0056] When the embossing roller 131 is transferred, the driving frame 21 returns, the support block 313 moves with the driving frame 21 towards the support roller 12, the driving rack 211 also returns with the driving frame 21, and the lifting frame 41 slides downward to lower the embossing roller 131 to be disassembled to a height convenient for carrying, at which time two people can easily lift the embossing roller 131 directly from the lifting frame 41 and carry it away, a hydraulic transfer trolley can be placed outside the lifting frame 41 in advance, and one person can move the embossing roller 131 after it is placed on the transfer trolley, greatly reducing manpower and improving the disassembly efficiency of the embossing roller 131, and only the forward and reverse rotation of the motor 119 is needed to achieve, and the control process is very simple.

[0057] In order to facilitate the installation of the embossing roller 131 to be used on the bearing seat 133, a second inclined groove 116 is arranged on the rack 11, the second inclined groove 116 is arranged at one end away from the first inclined groove 115, the two ends of the second inclined groove 116 are respectively communicated with the first horizontal groove 112 and the second horizontal groove 114, and a guide piece is arranged in the second horizontal groove 114, when the control rod 311 in the second horizontal groove 114 slides towards the lifting device, the control rod 311 enters the second inclined groove 116 under the guidance of the guide piece, the guide piece includes a guide plate 7 rotatably arranged in the second horizontal groove 114, the rotating shaft of the guide plate 7 is arranged at the opening of the second inclined groove 116 and close to the vertical groove 113, the bottom of the guide plate 7 abuts with the bottom surface of the second horizontal groove 114, at this time the guide plate 7 is flush with the bottom surface of the second inclined groove 116.

[0058] If the embossing roller 131 needs to be replaced, when the control rod 311 slides to the bottom of the first inclined groove 115 in the second horizontal groove 114, the lifting frame 41 has been lowered, the motor 119 stops rotating, the driving frame 21 stops sliding, at this time, the embossing roller 131 that needs to be replaced is taken off from the supporting block 411, the new embossing roller 131 is placed on the supporting block 411, then the motor 119 controls the driving frame 21 to slide towards the lifting frame 41, the control rod 311 slides towards the second inclined groove 116, at this time, the lifting frame 41 also slides upwards, under the guidance of the guide plate 7, the control rod 311 passes through the second inclined groove 116 and re-moves to the first horizontal groove 112, the supporting rod 31 is re-raised, the supporting block 313 is higher than the supporting block 411, at this time, although the supporting block 313 and the supporting block 411 are slightly misaligned in the horizontal direction, since the length of the supporting block 313 is greater than that of the supporting block 411, the embossing roller 131 on the supporting block 411 can still be raised by the supporting block 313, and then transferred to the supporting block 313, then the driving frame 21 slides towards the supporting roller 12, the embossing roller 131 follows the driving frame 21 and returns to the front end of the mounting frame 13, after the two ends of the embossing roller 131 are fixed on the bearing seat 133, the adjusting nut 3121 is rotated to slide the supporting block 313 downwards to a position where it does not interfere with the embossing roller 131.

[0059] In addition, in order to avoid the control rod 311 from falling from the first horizontal groove 112 to the second inclined groove 116, a second one-way control member is arranged at the communication between the second inclined groove 116 and the first horizontal groove 112, which is used to limit the control rod 311 to only enter the first horizontal groove 112 from the second inclined groove 116, the principle of the second one-way control member is similar to that of the first one-way control member, the second one-way control member comprises a second switch plate 6 rotatably arranged on the rack 11, the second switch plate 6 is arranged at the communication between the second inclined groove 116 and the first horizontal groove 112, the rotation shaft of the second switch plate 6 is arranged along the length direction of the control rod 311 and located at the end away from the vertical groove 113, when the second switch plate 6 is closed, the bottom surface of the second switch plate 6 is flush with the bottom surface of the first horizontal groove 112, the control rod 311 can only enter the first horizontal groove 112 from the second inclined groove 116, but cannot enter the second inclined groove 116 from the first horizontal groove 112.

[0060] The implementation principle of the embossing machine in the embodiment of the application is as follows: when the embossing roller 131 is to be disassembled, the adjusting nut 3121 is first rotated, the supporting block 313 abuts against the rotating shaft of the embossing roller 131, then the bearing seat 133 is disassembled, the embossing oil cylinder 132 drives the bearing seat 133 to move upward, and the connection between the bearing seat 133 and the embossing roller 131 is released; the motor 119 is forwardly rotated, the driving frame 21 slides toward the lifting frame 41, the mounting frame 13 first slides outwardly toward the rack 11, after the mounting frame 13 is slid to a position, the driving frame 21 continues to slide toward the lifting frame 41, and finally drives the supporting block 313 to slide to above the lifting frame 41; the control rod 311 falls from the first horizontal groove 112 to the second horizontal groove 114 under the action of gravity of the control rod 311 and the embossing roller 131, the supporting rod 31 and the supporting block 313 slide downward together, and the embossing roller 131 is transferred to the supporting block 411; the motor 119 is reversely rotated, the driving frame 21 is retreated, and the control rod 311 slides in the second horizontal groove 114 and together with the driving frame 21 toward the supporting roller 12.

[0061] If a new embossing roller 131 needs to be replaced, after the control rod 311 slides to below the first inclined groove 115, the embossing roller 131 to be disassembled is removed, the embossing roller 131 to be replaced is placed on the lifting frame 41, then the motor 119 is forwardly rotated, the driving frame 21 again slides toward the lifting frame 41, the control rod 311 passes through the second inclined groove 116 and enters the first horizontal groove 112, and at this time the embossing roller 131 on the lifting frame 41 is lifted by the supporting block 313; then the motor 119 is reversely rotated, and the control rod 311 returns to the initial position in the first horizontal groove 112; if a new embossing roller 131 does not need to be replaced, the driving frame 21 always slides toward the supporting roller 12, and the control rod 311 passes through the first inclined groove 115 and enters the first horizontal groove 112 to return to the initial position.
