Detailed Implementation

[0022] 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.

[0023] This application provides a tempering device, such as Figure 1 , 2 As shown, the tempering device 100 is arranged in the sheet production line, downstream of the calender 200, and is used to temper and shape the sheet output from the calender 200. The tempering device 100 includes a frame 10 extending in the front-rear direction and a roller assembly 20, a drive assembly 30, a traction assembly 40, and a trimming assembly 50 mounted on the frame 10.

[0024] The front end of the frame 10 is connected to the calender to receive the sheet output from the calender.

[0025] The roller assembly 20 includes a plurality of tempering rollers 1 arranged at intervals from front to back. The plurality of tempering rollers 1 extend in the left-right direction and are rotatably mounted on the frame 10. The top of the plurality of tempering rollers 1 forms a horizontal surface to support the sheet, so that the sheet can be smoothly conveyed backward while tempering the sheet.

[0026] Each tempering roller 1 is configured to allow hot water to pass through it. Several tempering rollers 1 of the roller assembly 20 are connected to a temperature control system (not shown in the figure), which provides hot water. The temperature control system precisely controls the roller surface temperature of each tempering roller 1 by adjusting the temperature of the hot water input to each tempering roller 1, thereby ensuring that the sheet material passing through the tempering device 100 is heated evenly.

[0027] In this embodiment, the roller assembly 20 includes eight tempering rollers 1, which allows the sheet to have sufficient distance for tempering, fully releases internal stress, and effectively improves the forming effect of the sheet and the quality of the final sheet product.

[0028] The drive assembly 30 is connected to the eight tempering rollers 1 of the roller assembly 20 for driving the eight tempering rollers 1 to rotate synchronously and at the same speed. The synchronous rotation of the eight tempering rollers 1 at the same speed can ensure the stable feeding of the sheet, avoid scratching the surface of the sheet due to inconsistent speed, and ensure the flatness and smoothness of the sheet.

[0029] The drive assembly 30 includes a drive motor 2 and several transmission belts 3. In this embodiment, the drive motor 2 is connected to a tempering roller 1 located at the rearmost side of the roller assembly 20 via the transmission belts 3, so as to drive the rearmost tempering roller 1 to rotate around its own axis. Transmission belts 3 are connected between adjacent tempering rollers 1, and several transmission belts 3 connect eight tempering rollers 1. When the rearmost tempering roller 1 rotates under the drive of the drive motor 2, the other seven tempering rollers 1 rotate synchronously and at the same speed as the rearmost tempering roller 1 under the transmission of the transmission belts 3.

[0030] Except for the foremost and rearmost tempering rollers 1, the other six tempering rollers 1 are connected at one end to the adjacent tempering roller 1 in front via a drive belt 3, and at the other end to the adjacent tempering roller 1 behind via a drive belt 3. The foremost tempering roller 1 has no tempering roller 1 in front of it, and only one end of it is connected to the adjacent tempering roller 1 behind it via a drive belt 3; the rearmost tempering roller 1 has no tempering roller 1 behind it, and one end of it is connected to the adjacent tempering roller 1 in front via a drive belt 3, and the other end of it is connected to the drive motor 2 via a drive belt 3.

[0031] Each tempering roller 1 has a pulley 4 installed at both ends to cooperate with the transmission belt 3, so as to improve the stability of the transmission connection between the eight tempering rollers 1.

[0032] The traction assembly 40 is arranged near the rear end of the frame 10. The traction assembly 40 includes a traction roller 5 parallel to the tempering roller 1. The traction roller 5 corresponds to the tempering roller 1 located on the rear side in the roller assembly 20 and is located directly above the tempering roller 1 on the rear side. The traction roller 5 is configured to press the sheet onto the corresponding tempering roller 1 from top to bottom. When the tempering roller 1 rotates, the traction roller 5 cooperates with it to pull the sheet from front to back, effectively preventing the sheet from deviating.

[0033] The traction assembly 40 also includes a traction cylinder 6 that is connected to the traction roller 5 for driving the traction roller 5 to move closer to and away from the corresponding tempering roller 1.

[0034] The edge-cutting assembly 50 is mounted adjacent to the front end of the frame 10. The edge-cutting assembly 50 includes at least one pair of cutters 7 for cutting sheets. The at least one pair of cutters 7 is located above the roller assembly 20 and spaced apart in the left-right direction. Each cutter 7 is configured to be movable in the left-right direction and to rotate about a center line extending in the left-right direction, thereby enabling the cutting of sheets with different thicknesses and width requirements.

[0035] The edge-cutting assembly 50 also includes a plurality of support rollers 8 mounted on the frame 10. The plurality of support rollers 8 are arranged at intervals in the left-right direction and are all adjacent to at least one pair of cutters 7. The plurality of support rollers 8 cooperate with the tempering roller 1 to support the sheet being cut, prevent the sheet from warping during cutting, and ensure the flatness of the cut surface.

[0036] 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. Various changes and modifications can be made without departing from the spirit and scope of this application. The scope of protection claimed by this application is defined by the appended claims, specification, and their equivalents.
