Description

Technical Field

[0001] This utility model relates to the field of laminating machine technology, and more specifically, to a face laminating machine. Background Technology

[0002] For the lamination processing needs of paper and film, laminating machines offer two main solutions: instant coating and pre-coating. Instant coating laminating machines complete the lamination process through three steps: gluing, drying, and hot pressing. Due to their excellent applicability and stable and reliable performance, they are the most widely used in the domestic laminating equipment market.

[0003] During the lamination process, since the cardboard pieces are individual units, the film needs to be cut. Current cutting structures often use a cylinder to drive a horizontally positioned slitting blade to cut the film. This process has the following shortcomings that require improvement: 1. After prolonged cutting operations, the cutting edge of the slitting blade will inevitably wear down and become dull, resulting in rough film edges and reduced slitting accuracy. Replacing the worn blade requires shutting down the entire laminating production line. This frequent and time-consuming downtime for maintenance severely reduces effective production time and significantly lowers the overall efficiency of the laminating equipment.

[0004] 2. The slitting blade generates continuous high-frequency vibration during its high-speed reciprocating motion. This vibration acts on the blade and its mounting base over a long period, which can easily lead to loosening of the fixing screws or slight deformation of the blade holder support structure, causing the blade to deviate or shift at an angle. This loss of installation accuracy directly results in uneven cuts, tilted cut surfaces, or deviations in slitting dimensions, severely affecting the slitting effect.

[0005] 3. The slitting blade can only perform vertical reciprocating motion, resulting in a limited cutting method. When dealing with thin film materials with good toughness, the vertical downward cutting force is insufficient to completely sever the film fibers instantly. This often results in incomplete cuts that do not penetrate the film thickness, leading to poor slitting performance. Utility Model Content

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a laminating machine, comprising two mounting plates, with a cylinder fixedly connected to each of the two mounting plates. A fixing block is fixedly connected to the telescopic end of the cylinder. A spline sleeve is rotatably connected between the two fixing blocks. A sliding sleeve is splinedly connected to the spline sleeve. Two mounting seats are fixedly connected to the sliding sleeve. A slitting blade is detachably connected to each mounting seat.

The gear meshes with an adjacent gear ring. The fixing block on the right side is provided with a limit structure, and the fixing block on the left side is provided with a reciprocating structure.

[0008] The present invention is further configured such that the two slitting blades are symmetrically distributed with respect to the sliding sleeve, and both slitting blades are parallel to the cylinder.

[0009] The present invention is further configured such that the limiting structure includes a limiting block one, the limiting block one is fixedly connected to the right end of the spline sleeve, the fixing block on the right side is fixedly connected to a bracket one, the bracket one is fixedly connected to a fixing plate, the fixing plate is spline-connected to a spline rod one, and the spline rod one is fixedly connected to a limiting block two.

[0010] The present invention is further configured such that the first limiting block is provided with a cross-shaped limiting groove, and the first limiting block and the cross-shaped limiting groove of the second limiting block cooperate in a limiting manner.

[0011] The present invention is further configured such that a second cylinder is fixedly connected to the first bracket, and the telescopic end of the second cylinder is fixedly connected to the right end of the first spline rod.

[0012] The present invention is further configured such that the reciprocating structure includes a sliding rod, the sliding rod is slidably connected to the spline sleeve, the spline sleeve is provided with a through groove, a connecting block is slidably connected in the through groove of the spline sleeve, the connecting block is fixedly connected to the sliding rod, the connecting block is fixedly connected to the sliding sleeve, a second bracket is fixedly connected to the fixing block on the left side, a second spline rod is slidably connected to the second bracket, and the second spline rod is rotatably connected to the sliding rod.

[0014] (III) Beneficial Effects Compared with the prior art, the present invention provides a laminating machine with the following advantages: 1. This utility model utilizes a symmetrically installed two slitting blades with a splined linkage structure, combined with the 180° rotation function of the motor-driven gear ring, to quickly switch to a spare blade when the lower slitting blade wears out. This design eliminates the production line downtime required for traditional blade replacement, effectively avoiding production capacity losses caused by downtime maintenance and significantly improving the continuous operation efficiency of the laminating machine.

[0015] 2. This utility model employs a dynamic locking design with a cross-shaped limiting block in its limiting structure. During tool change, the limiting block is released to allow the spline sleeve to rotate freely; during operation, the rotating shaft is rigidly locked, effectively suppressing the risk of tool deviation caused by cutting vibration. Simultaneously, the detachable mounting base simplifies the tool replacement process and reduces the difficulty of long-term maintenance.

[0016] 3. This utility model innovatively integrates vertical reciprocating motion and lateral reciprocating motion. This composite cutting trajectory of vertical + horizontal significantly enhances the shearing force on high-toughness films, completely avoids the "broken threads" phenomenon that is prone to occur in traditional vertical cutting, and ensures that the cut edge is flat and burr-free.

[0022] Please see Figures 1-7 A laminating machine includes two mounting plates 1, with cylinder 2 fixedly connected to each mounting plate 1. A fixing block 3 is fixedly connected to the telescopic end of cylinder 2. A spline sleeve 4 is rotatably connected between the two fixing blocks 3. A sliding sleeve 5 is splinedly connected to the spline sleeve 4. Two mounting seats 6 are fixedly connected to the sliding sleeve 5. A slitting blade 7 is detachably connected to the mounting seats 6. Gear rings 8 are fixedly connected to both ends of the spline sleeve 4. A motor 9 is fixedly connected to the fixing block 3. A gear 10 is fixedly connected to the output end of the motor 9. The gear 10 meshes with the adjacent gear ring 8. The fixing block 3 on the right side is provided with a limit structure, and the fixing block 3 on the left side is provided with a reciprocating structure. The two slitting blades 7 are symmetrically distributed with respect to the sliding sleeve 5, and both slitting blades 7 are parallel to cylinder 2.

[0023] In this embodiment, two mounting plates are first installed on the laminating machine body. The two cylinders 2 reciprocate through their telescopic ends, and the two fixed blocks 3 drive the sliding sleeve 5 and the slitting blade 7 to move up and down through the spline sleeve 4 to slit the film. During the film slitting process, if the slitting blade 7 located on the lower side wears down, resulting in a reduction in the film slitting effect, two motors 9 are started while the two cylinders 2 drive the spline sleeve 4 and the slitting blade 7 on it to move downward. The output end of the motors 9 drives the gear 10 to rotate, and the gear 10 drives the adjacent gear ring 8 to rotate. At the same time, the spline sleeve 4 rotates 180°, and the positions of the two slitting blades 7 are swapped. This allows for the rapid replacement of the slitting blade 7 without stopping the laminating machine, ensuring the working efficiency of the laminating machine. When the laminating machine stops working, the worn slitting blade 7 can be replaced.

[0024] Please see Figure 1 , Figure 4 and Figure 5The limiting structure includes a limiting block 11, which is fixed to the right end of the spline sleeve 4. A bracket 12 is fixed to the right side of the fixing block 3. A fixing plate 13 is fixed to the bracket 12. A spline rod 14 is splined to the fixing plate 13. A limiting block 2 15 is fixed to the spline rod 14. The limiting block 11 is provided with a cross limiting groove. The limiting block 11 and the cross limiting groove of the limiting block 2 15 are mutually limiting. A cylinder 2 16 is fixed to the bracket 12. The telescopic end of the cylinder 2 16 is fixed to the right end of the spline rod 14.

[0025] In this embodiment, initially, limit block 11 and limit block 2 15 are in a pressing contact state. When it is necessary to change the position of the two slitting blades 7, cylinder 2 16 is started first. The extension end of cylinder 2 16 drives spline rod 14 to move to the right. During the movement of spline rod 14 along the fixed plate 13 to the right, limit block 2 15 is moved at the same time. Limit block 2 15 loses contact with limit block 11. After the two slitting blades 7 are swapped, the extension end of cylinder 2 16 is then controlled to reset, so that limit block 2 15 limits limit block 11 again, thereby limiting the spline sleeve 4 and improving the stability of the slitting blades 7 during operation.

[0026] Please see Figure 1 , Figure 6 and Figure 7 The reciprocating structure includes a sliding rod 17, which is slidably connected to a spline sleeve 4. The spline sleeve 4 is provided with a through groove, and a connecting block 18 is slidably connected in the through groove of the spline sleeve 4. The connecting block 18 is fixedly connected to the sliding rod 17 and the sliding sleeve 5. A second bracket 19 is fixedly connected to a fixed block 3 on the left side. A second spline rod 20 is slidably connected to the second bracket 19 and is rotatably connected to the sliding rod 17. A guide plate 21 is fixedly connected to the second spline rod 20, and the guide plate 21 is provided with a guide groove. A third bracket 22 is fixedly connected to the fixed block 3 on the left side. A second motor 23 is fixedly connected to the third bracket 22. The output shaft of the second motor 23 is fixedly connected to a fixed disk 24. A fixed rod 25 is fixedly connected to the eccentric position of the fixed disk 24 and slides in the guide groove of the guide plate 21.

[0027] In this embodiment, during the film slitting process of the slitting blade 7, the second motor 23 is started. The output shaft of the second motor 23 drives the fixed disk 24 on it to rotate circumferentially. The fixed disk 24 drives the fixed rod 25 to rotate circumferentially. The fixed rod 25 slides along the guide groove of the guide plate 21, thereby causing the guide plate 21 to drive the spline rod 20 to slide left and right. The spline rod 20 drives the sliding rod 17 to slide along the spline sleeve 4. The sliding rod 17 drives the sliding sleeve 5 to slide left and right along the spline sleeve 4 through the connecting block 18. The two slitting blades 7 move together with the sliding sleeve 5. Therefore, when slitting the film, the slitting blades 7 move left and right while slitting the film downwards, thereby improving the slitting effect of the film. When changing the slitting blades 7, the sliding rod 17 rotates along the spline rod 20, which does not affect the normal replacement of the slitting blades 7.

For all the fixed connections mentioned above, welding is preferred.
