[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 cooling bracket for various plastic sheets, such as... Figure 1 , 3As shown, the cooling bracket 10 is arranged between the three-roll calender 20 and the traction machine 30 to support the sheet metal output from the three-roll calender 20. The traction machine 30 provides a front-to-back traction force to the sheet metal from the rear side of the cooling bracket 10. The rear side of the three-roll calender 20 can be optionally equipped with a corrugated sheet forming machine 40 or a cooling roller group 50 to accommodate the production of corrugated and flat sheets, depending on production needs. This cooling bracket can quickly adapt to the production switch between flat and corrugated sheets without large-scale equipment modifications, offering multiple uses, reducing production costs, and effectively minimizing the equipment's footprint.

[0024] The cooling bracket 10 includes a front bracket 1 and a rear bracket 2 that both extend in the front-rear direction. The front bracket 1 is located in front of the rear bracket 2, and the rear end of the front bracket 1 overlaps the front end of the rear bracket 2. The top surfaces of the two are flush to ensure the flat conveying of the plate.

[0025] The front end of the front bracket 1 can be detachably fitted with an extension bracket 3 according to the production requirements of the sheet material, to adapt to the production of different sheet materials. When producing corrugated sheets, a corrugated sheet forming machine 40 is located behind the three-roll calender 20, and the front end of the front bracket 1 is directly connected to the frame of the corrugated sheet forming machine 40. When producing flat sheets, a cooling roller assembly 50 is located behind the three-roll calender 20. The distance between the rear end of the cooling roller assembly 50 and the front end of the rear bracket 2 is greater than the distance between the rear end of the corrugated sheet forming machine 40 and the front end of the rear bracket 2, requiring an extension of the front bracket 1. Therefore, an extension bracket 3 is added to the front end of the front bracket 1. The rear end of the extension bracket 3 is connected to the front end of the front bracket 1 by several mechanical fasteners, and the front end of the extension bracket 3 is connected to the rear end of the cooling roller assembly 50 by several mechanical fasteners. The overall length of the front bracket 1 is adjusted by the extension bracket 3, resulting in a simple structure, convenient operation, and effective reduction of equipment costs.

[0026] A support mechanism 4 is provided below the front end of the rear bracket 2, and the rear end of the rear bracket 2 is connected to the traction machine 30. The support mechanism 4 can adjust the height of the front end of the rear bracket 2 in the vertical direction to ensure that the top surface of the rear bracket 2 is always flush with the top surface of the front bracket 1. The support mechanism 4 includes a support column 41 and a raising column 42. The support column 41 is supported on the ground, and the raising column 42 can be selectively installed on top of the support column 41 according to production needs.

[0027] like Figure 3As shown, during the production of corrugated sheets, the sheet material is positioned relatively low when output from the corrugated sheet forming machine 40. During the production of flat sheets, the sheet material is routed from the upper roller of the three-roll calender 20 and then conveyed backward via the cooling roller assembly 50. The horizontal position of the sheet material output from the cooling roller assembly 50 is higher than its horizontal position when output from the corrugated sheet forming machine 40. To ensure flat conveying of the sheet material, during corrugated sheet production, the front support 1 is connected to the rear side of the corrugated sheet forming machine 40 at a low position, and the front end of the rear support 2 is directly supported on the ground only by the support column 41. Figure 1 As shown, during the production of the flat plate, the front bracket 1 is connected to the rear end of the cooling roller assembly 50 at a higher position. In order to be flush with the front bracket 1, the front end of the rear bracket 2 is raised by installing a shim column 42 on the support column 41 to raise the horizontal position of the rear end of the front bracket 1, so as to ensure the smooth connection between the front bracket 1 and the rear bracket 2.

[0028] like Figure 1 , 3 As shown in Figure 5, both the support column 41 and the raised column 42 are equipped with lifting adjustment components 43. The lifting adjustment components 43 include a lifting screw 431 and a connecting sleeve 432. The connecting sleeve 432 can be hinged to the rear bracket by bolts, and the connecting sleeve 432 is sleeved on the top end of the lifting screw 431 so that the lifting screw 431 can rotate freely about its own axis relative to the connecting sleeve 432. The top of both the support column 41 and the raised column 42 are provided with threaded holes that are threaded to the corresponding lifting screw 431. When the lifting screw 431 rotates about its own axis, the lifting screw 431 can drive the corresponding connecting sleeve 432 to move up and down relative to the support column 41 or the raised column 42. In this embodiment of the application, the lifting screw 431 is provided with an operating part 4310 for clamping with a wrench. The operating part 4310 is not threaded. The operator clamps the operating part 4310 with a wrench and drives the lifting screw 431 to rotate. During the rotation of the lifting screw 431, the front end of the rear bracket 2 is driven to rise and fall, thereby realizing the fine adjustment of the height of the front end of the rear bracket 2.

[0029] like Figure 2 , 4 As shown, the front bracket 1 includes a plurality of first cooling rollers 11 spaced apart from front to back, the rear bracket 2 includes a plurality of second cooling rollers 21 spaced apart from front to back, and the extended bracket 3 includes a plurality of third cooling rollers 31 spaced apart from front to back. The plurality of first cooling rollers 11, the plurality of second cooling rollers 21 and the plurality of third cooling rollers 31 are parallel to each other.

[0030] In the production of flat plates, the top surfaces of several first cooling rollers 11, several second cooling rollers 21, and several third cooling rollers 31 are located in the same plane. In the production of corrugated plates, the top surfaces of several first cooling rollers 11 and several second cooling rollers 21 are located in the same plane. These rollers form a continuous, flat support surface, jointly supporting and conveying the product to ensure its flatness and continuous transport.

[0031] like Figure 1-4 As shown, a trimming device 5 is also installed on the front bracket 1. The trimming device 5 includes at least one pair of cutters for cutting products in the front-to-back direction. The at least one pair of cutters are spaced apart in the left-to-right direction. Each cutter can move in the left-to-right direction and can rotate about an axis extending in the left-to-right direction. The position of each cutter in the left-to-right direction can be adjusted to accommodate trimming of products of different widths. The rotation of each cutter can adjust the cutting angle to accommodate cutting of products of different thicknesses, thereby improving the applicability of the equipment.

[0032] The working process of this application is as follows: When producing corrugated sheets, a corrugated sheet forming machine 40 is installed on the rear side of the three-roll calender 20. The front end of the front bracket 1 is directly connected to the outlet of the corrugated sheet forming machine 40. The front end of the rear bracket 2 is only supported by the support column 41 and no shim column 42 is installed. After the corrugated sheet comes out of the three-roll calender 20, it enters the corrugated sheet forming machine 40 for shaping. Then it is cooled and conveyed on the front bracket 1 and the rear bracket 2 in sequence. Finally, it is pulled to the subsequent station by the traction machine 30. When producing flat plates, a cooling roller assembly 50 is installed after the three-roll calender 20. An extended bracket 3 is installed at the front end of the front bracket 1, and the front end of the extended bracket 3 is connected to the rear end of the cooling roller assembly 50. A shim column 42 is installed on the support column 41, and the height is adjusted by the lifting adjustment assembly 43 so that the rollers of the extended bracket 3, the front bracket 1 and the rear bracket 2 are in the same plane. After the flat plate comes out of the three-roll calender 20, it is initially cooled by the cooling roller assembly 50, and then further cooled and conveyed by the extended bracket 3, the front bracket 1 and the rear bracket 2 in sequence. Finally, it is pulled to the next station by the traction machine 30.

[0033] This application enables quick and convenient switching between flat and corrugated board production lines simply by disassembling and assembling extended brackets and raised columns, and connecting different upstream equipment, effectively improving equipment utilization and production flexibility.

[0034] 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.
