[0030] To illustrate the technical content, structural features, achieved objectives, and effects of the application in detail, the technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, structure, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0031] This application provides a cross-cutting device, which is arranged on a sheet product production line and is used to cut the sheet products conveyed to it according to production requirements.

[0032] like Figure 1 As shown, the cross-cutting device includes: a base frame 10 supported on the ground, a longitudinal movement mechanism 20 mounted on the base frame 10, a cross-cutting mechanism 30 mounted on the longitudinal movement mechanism 20, and a folding bracket 40 arranged in front of the longitudinal movement mechanism 20.

[0033] The longitudinal transfer mechanism 20 includes a longitudinal transfer frame 1 mounted on a base frame 10, capable of reciprocating in the front-to-back direction, and a longitudinal transfer drive device for driving the longitudinal transfer frame 1 to move in the front-to-back direction. The top of the longitudinal transfer frame 1 has a cutting platform 101 that carries the product. The longitudinal transfer drive device drives the longitudinal transfer frame 1 to move at a speed that matches the linear speed of the production line, ensuring that the cutting platform 101 and the product it carries are relatively stationary, so that the transverse cutting mechanism 30 can smoothly cut the product in the left-to-right direction.

[0034] like Figure 1 , 2 As shown in Figure 5, the longitudinal traverse drive device includes a rack 21 extending in the front-to-back direction, a gear (not shown) meshing with the rack 21, and a longitudinal traverse motor 22 connected to the gear drive. Both the gear and the longitudinal traverse motor 22 are mounted on the longitudinal traverse frame 1, and the rack 21 is mounted on the base frame 10. The longitudinal traverse motor 22 drives the gear to rotate relative to the rack 21. The tooth surface of the rotating gear abuts against the tooth surface of the rack 21, and the relative action of the two causes the gear to move relative to the rack 21 in the front-to-back direction, thereby driving the longitudinal traverse frame 1.

[0035] A first sliding assembly 3 is provided between the longitudinal transfer frame 1 and the base frame 10. The first sliding assembly 3 includes a first guide rail 31 extending in the front-back direction and a first slider 32 that slides with the first guide rail 31. The first guide rail 31 is mounted on the base frame 10, and the first slider 32 is mounted on the bottom of the longitudinal transfer frame 1. The first sliding assembly 3 is used to guide the movement of the longitudinal transfer frame 1 and prevent the longitudinal transfer frame 1 from falling off the base frame 10 during the front-back movement.

[0036] like Figure 1 , 2 As shown in Figures 5 and 6, the transverse cutting mechanism 30 is mounted on the longitudinal frame 1. The transverse cutting mechanism 30 includes a cutting device 4 and a transverse drive device 5. The cutting device 4 includes a mounting base 41, a cutting blade 42, and a cutting motor 43 for driving the cutting blade 42 to rotate. At least a portion of the cutting blade 42 extends upward above the cutting platform 101. In this embodiment, the cutting blade 42 is a circular saw blade. The cutting motor 43 is mounted on the mounting base 41, and the cutting blade 42 is coaxially arranged with the output shaft of the cutting motor 43, thereby rotating around its own axis under the drive of the cutting motor 43. The transverse drive device 5 is connected to the mounting base 41 to drive the cutting device 4 to reciprocate in the left-right direction relative to the cutting platform 101. During the rotation of the cutting blade 42, it is driven to move in the left-right direction, so that the cutting blade 42 can cut the products on the cutting platform 101 in the left-right direction.

[0037] The lateral drive device 5 includes a lead screw 51 extending in the left-right direction, a lead screw nut threadedly engaged with the lead screw 51, and a lateral drive motor 53 connected to the lead screw 51. The lead screw nut is connected to the mounting base 41. In this embodiment, the lateral drive motor 53 is offset to one side of the lead screw 51 and is connected to the lead screw 51 via a synchronous pulley structure, thereby driving the lead screw 51 to rotate around its own axis. When the lead screw 51 rotates around its own axis, the lead screw nut can move back and forth relative to the lead screw 51 in the left-right direction. The mounting base 41 connected to the lead screw nut can drive the entire cutting device 4 to move in the left-right direction, thereby realizing the drive of the cutting device 4 by the lateral drive device 5.

[0038] A second sliding assembly 6 is provided between the cutting device 4 and the longitudinal frame 1. The second sliding assembly 6 includes a second guide rail 61 extending in the left-right direction and a second slider 62 that slides with the second guide rail 61. The second guide rail 61 is mounted on the longitudinal frame 1, and the second slider 62 is connected to the mounting base 41. The second sliding assembly 6 guides the left-right movement of the cutting device 4.

[0039] like Figure 1 , 5 As shown in Figures 8 and 9, in this embodiment of the application, the cutting blade 42 and the cutting motor 43 are mounted on a sliding seat 44. The sliding seat 44 can move vertically relative to the mounting base 41 via a lifting cylinder 46 installed between the sliding seat 44 and the mounting base 41. The cutting blade 42 moves up and down with the sliding seat 44 to adjust the height of the cutting platform 101 exposed, thereby adapting to the cutting of products of different thicknesses. A third sliding assembly 45 is also provided between the sliding seat 44 and the mounting base 41. The third sliding assembly 45 includes a third guide rail 451 extending vertically and a third slider 452 that slides with the third guide rail 451. The third guide rail 451 is mounted on the mounting base 41, and the third slider 452 is mounted on the sliding seat 44. At least one pair of third sliding assemblies 45 is provided between the sliding seat 44 and the mounting base 41, and each pair of third sliding assemblies 45 is symmetrically arranged on both sides of the sliding seat 44, thereby improving the stability during the lifting process.

[0040] like Figure 6 , 7 As shown, a cutting opening 102 extending in the left-right direction is provided on the cutting platform 101. The cutting opening 102 allows the cutting blade 42 to extend from the lower part of the cutting platform 101 and provides space for the left-right movement of the cutting blade 42.

[0041] like Figure 1-4As shown, when the cutting platform 101 moves backward, the distance between the cutting platform 101 and the upstream equipment increases, causing the product between the cutting platform 101 and the upstream equipment to lose its support and easily fall due to gravity. The fall can cause the product to bend or break, and after the product is transversely cut, one end of the cut edge will curl up, affecting subsequent transverse cutting work. In order to ensure the stability of cutting, a folding bracket 40 is installed on the front side of the cutting platform 101. The folding bracket 40 is located on the same horizontal plane as the cutting platform 101. The folding bracket 40 includes a number of first brackets 7 and a number of second brackets 8 arranged alternately in the left-right direction. Each first bracket 7 and each second bracket 8 extends in the front-back direction. The number of first brackets 7 are fixedly installed at the front end of the cutting platform 101, and the number of second brackets 8 are fixedly installed above the base frame 10 by a bracket. When the longitudinal frame 1 moves backward, the distance between the rear end of the first bracket 7 and the front end of the second bracket 8 increases; when the longitudinal frame 1 moves forward, the distance between the rear end of the first bracket 7 and the front end of the second bracket 8 decreases. The alternating design of the first bracket 7 and the second bracket 8 enables the folding function of the folding bracket 40 when the longitudinal frame 1 moves back and forth. When the longitudinal frame 1 moves back and forth, the folding bracket 40 always supports the product between the cutting platform 101 and the upstream equipment, preventing the product from bending, warping, and falling during the cross-cutting process, thus improving the stability and cutting effect of the cross-cutting.

[0042] Multiple rollers 9 are rotatably mounted on both the first bracket 7 and the second bracket 8. The rollers 9 on each bracket are arranged at intervals in the front-to-back direction, and each roller 9 can rotate around the axis extending in the left-to-right direction. The rollers contact the product, reducing the friction between the bracket and the product.

[0043] like Figure 1 , 3 As shown in Figure 6, a clamping device 50 is also provided above the cutting platform 101. The clamping device 50 includes a clamping block 11 and a clamping cylinder 12. The clamping cylinder 12 is connected to the clamping block 11 to drive the clamping block 11 to move in the vertical direction. The clamping block 11 corresponds to the cutting opening 102. The bottom of the clamping block 11 has a cutting groove 110 that cooperates with the cutting opening 102. The cutting groove 110 extends in the horizontal direction and is configured to accommodate the cutting blade 42 exposed above the cutting platform 101. The clamping block 11 falls before the cutting blade 42 makes a horizontal cut to press the product firmly onto the cutting platform 101, so as to ensure that the product will not move during the cutting process of the cutting blade 42 and to ensure the flatness of the product's cut surface.

[0044] like Figure 2-4As shown, a transition bracket 60 is installed at the rear end of the cutting platform 101, supporting the product behind the cutting platform 101. The transition bracket 60 includes a plurality of transition aluminum rollers 13 extending in the left-right direction and a plurality of transition support plates 14 extending in the left-right direction. The plurality of transition aluminum rollers 13 and the plurality of transition support plates 14 are arranged alternately in the front-back direction. The plurality of transition support plates 14 are used to support the cut product on the rear side of the cutting platform 101. At least a portion of each transition aluminum roller 13 is located on the upper side of the adjacent transition support plate 14. The transition aluminum rollers 13 are used to reduce the friction between the product and the transition support plate 14 and increase the conveying efficiency.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments.
