[0015] 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.

[0016] This application provides an online transverse hot cutting device for transversely cutting plastic sheets, ensuring a flat end face of the cut, effectively eliminating burrs, and improving the appearance quality of the cut plastic sheets. It is especially suitable for cutting PP honeycomb panels and PC hollow panels.

[0017] like Figure 1 As shown, the online transverse hot cutting equipment 100 includes a frame 10, a longitudinal movement mechanism 20 and a transverse cutting mechanism 30. The frame 10 is supported on the ground, and the longitudinal movement mechanism 20 and the transverse cutting mechanism 30 are both mounted on the frame 10.

[0018] like Figure 1 , 3 As shown, the longitudinal movement mechanism 20 includes a cutting base 1 that is movable in the front-back direction and mounted on the frame 10, a support bracket 2 mounted on the front end and rear end of the cutting base 1, and a longitudinal movement drive assembly 3 that is connected to the cutting base 1 in a transmission manner. The longitudinal movement drive assembly 3 is used to drive the cutting base 1 to move back and forth.

[0019] The support bracket 2 includes several rotating rollers 21 arranged at intervals from front to back. Each rotating roller 21 extends in the left-right direction. The support bracket 2 supports the plastic sheet being cut on the front and rear sides of the cutting base 1. The several rotating rollers 21 reduce the friction between the plastic sheet and the cutting base 1, ensuring that the plastic sheet is smoothly conveyed in the front-back direction.

[0020] The longitudinal drive assembly 3 includes a longitudinal guide rail 31 extending in the front-to-back direction and a moving rack 32, a longitudinal slider 33 slidably engaged with the longitudinal guide rail 31, a moving gear 34 meshing with the moving rack 32, and a longitudinal motor 35 drivenly connected to the moving gear 34. The longitudinal guide rail 31 and the moving rack 32 are mounted on the frame 10, and the longitudinal slider 33 and the longitudinal motor 35 are mounted on the cutting base 1. The longitudinal motor 35 drives the moving gear 34 to rotate around its own axis. During rotation, the moving gear 34 abuts against the tooth surface on the moving rack 32, thereby driving the cutting base 1 to move back and forth relative to the frame 10. The longitudinal slider 33 slidably engages with the longitudinal guide rail 31, which on the one hand reduces the friction between the cutting base 1 and the frame 10 during back-to-back movement, and on the other hand guides the back-to-back movement of the cutting base 1.

[0021] like Figure 2 , 3 As shown, the transverse cutting mechanism 30 is mounted on the cutting base. The transverse cutting mechanism 30 includes a cutting assembly 4 and a transverse drive assembly 5 that is pulsatorically connected to the cutting assembly 4. The cutting assembly 4 includes a blade 41 for transversely cutting the plastic sheet and a cast aluminum heating plate 42 that is close to the blade 41. The transverse drive assembly 5 is used to drive the blade 41 to move left and right relative to the cutting base 1 to transversely cut the plastic sheet.

[0022] The cutting base 1 has a cutting opening (not shown in the figure) through which the blade 41 passes from bottom to top. The cutting opening extends in the left and right direction, and the blade 41 moves left and right at the cutting opening under the drive of the transverse drive assembly 5.

[0023] like Figure 1-3As shown, the cutting assembly 4 includes a blade holder 43, with the blade 41 and cast aluminum heating plate 42 all mounted on the blade holder 43. The transverse drive assembly 5 includes a transverse guide rail 51 extending in the left-right direction, a transverse slider 52 slidably engaged with the transverse guide rail 51, a driving sprocket 53 and a driven sprocket 54 arranged opposite each other, a drive chain 55, and a transverse motor 56 connected to the driving sprocket 53. The transverse guide rail 51 is mounted on the cutting base 1, the transverse slider 52 is mounted on the blade holder 43, the driving sprocket 53 and the driven sprocket 54 are rotatably mounted on the cutting base 1, and the drive chain 55 passes over both the driving sprocket 53 and the driven sprocket 54. The transverse motor 56 drives the driving sprocket 53 to rotate around its own axis. The blade holder 43 is connected to the drive chain 55 via a connecting block, thus enabling it to move left and right with the drive chain 55. The transverse motor 56 drives the drive sprocket 53 to rotate. The drive sprocket 53 rotates under the drive of the transverse motor 56, thereby causing the meshing transmission chain 55 to move in the left-right direction. This further drives the cutter holder 43 to move the blade 41 in the left-right direction, enabling the transverse cutting of the plastic sheet. The transverse slider 52 and the transverse guide rail 51 slide together to guide the movement of the cutter holder 43.

[0024] A clamping assembly 6 is installed above the cutting base 1. The clamping assembly 6 includes a clamping block 61 and a clamping cylinder 62 that is pulsatorically connected to the clamping block 61. The clamping cylinder 62 is used to drive the clamping block 61 to move in the vertical direction. When the cross-cutting mechanism 30 cross-cuts the plastic sheet, the clamping cylinder 62 drives the clamping block 61 to move downward to press the plastic sheet onto the cutting base 1, preventing the plastic sheet from shifting during cutting and ensuring smooth cutting and a flat cut.

[0025] like Figure 4 As shown, the cast aluminum heating plate 42 includes an aluminum housing 421 and a heating wire 422 embedded within the aluminum housing 421. The aluminum housing 421 is die-cast into a plate shape, and the heating wire 422 is arranged in an "S" shape within the aluminum housing 421, thereby enabling uniform heating of the closely attached blade 41. The aluminum housing 421 has fast thermal conductivity, allowing the heat from the heating wire 422 to be transferred to the blade 41 evenly and quickly, reducing heat loss and improving heat utilization efficiency. Heated by the cast aluminum heating plate 42, the blade 41 produces a smooth cut when cutting plastic sheets, effectively eliminating burrs and reducing wear on the blade 41, thus extending its service life.

[0026] 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. The embodiments and descriptions in the specification are merely illustrative of the principles of this application.
