Detailed implementation manners

[0016] To describe in detail the technical content, structural features, achieved objectives and effects of the application, the following will describe the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments can also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments can be different, but do not have to be exclusive. For example, without departing from the inventive concept, the specific shapes, structures and characteristics of the exemplary embodiments can be used or implemented in another exemplary embodiment.

[0017] Hereinafter, terms such as "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0018] The "upper", "lower", "front", "rear", "left" and "right" described in the present application are in accordance with the upper, lower, front, rear, left and right shown in the attached Figure 1 drawings.

[0019] In this application, unless otherwise clearly specified and defined, the term "connection" shall be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral one; it can be directly connected or indirectly connected through an intermediate medium.

[0020] An embodiment of this application provides a sheet cooling device, as Figure 1 shown, the sheet cooling device 10 is arranged between a calender 20 that can move back and forth and a tractor 30. The calender 20, the sheet cooling device 10, and the tractor 30 are arranged in sequence from front to back to convey the sheet from front to back.

[0021] The sheet cooling device 10 includes a bracket 1 connected between the calender 20 and the tractor 30, a plurality of cooling rollers 2 arranged on the bracket 1 in sequence from front to back, and a platform 3 erected on the bracket 1.

[0022] As Figures 3 - 5 shown, the bracket 1 has a first end 101 connected to the calender 20 and a second end 102 connected to the tractor 30. The first end 101 and the second end 102 have a horizontal distance L in the front-rear direction. This horizontal distance L is the distance between the calender 20 and the tractor 30 in the front-rear direction. Since the calender 20 can move back and forth in the front-rear direction, the horizontal distance L of the bracket 1 can be adjusted to adapt to the distance between the calender 20 and the tractor 30.

[0023] The bracket 1 includes a front bracket 11 and a rear bracket 12 arranged in sequence from front to back. The front bracket 11 has a rear end portion 111 slidably connected to the rear bracket 12, and the rear bracket 12 has a front end portion 121 slidably connected to the front bracket 11. The rear end portion 111 is located above the front end portion 121; a sliding structure 13 is arranged between the front bracket 11 and the rear bracket 12. The sliding structure 13 enables the front bracket 11 to move relative to the rear bracket 12 in the front-rear direction to change the size of the horizontal distance L, so that the bracket 1 can adapt to the changing distance between the calender 20 and the tractor 30.

[0024] As Figure 2 、 4 shown, the sliding structure 13 includes at least a pair of moving wheels 131 and a connecting bracket 132 connecting the moving wheels 131 to the front bracket 11. The front end portion 121 of the rear bracket 12 forms a track for at least a pair of moving wheels 131 to move back and forth. At least a pair of moving wheels 131 are rotatably connected to the lower side of the rear end portion 111 of the front bracket 11 through the connecting bracket 132, and at least a pair of moving wheels 131 can move in the front-rear direction on the front end portion 121.

[0025] In an embodiment of the present application, a pair of moving wheels 131 are provided at the rear end portion 111 of the front bracket 11, which are arranged opposite to each other left and right. The axis lines of the pair of moving wheels 131 all extend in the left-right direction. Each moving wheel 131 has a groove 133 that radially indents inward in the circumferential direction. At least a part of the front end portion 121 is received in the groove 133 of the moving wheel 131 to guide the movement of the moving wheel 131.

[0026] As Figure 3 , 4 shown, a plurality of support columns 14 are further provided at the bottom of the rear bracket 12. Each support column 14 extends in the up-down direction to support the rear bracket 12 on the ground. At least a pair of support columns 14 are connected to the bottom of the front end portion 121 of the rear bracket 12 opposite to each other left and right to support the sliding structure 13 and the front end portion 121 and the rear end portion 111 slidably connected through the sliding structure 13, strengthening the supporting force of the rear bracket 12 at the front end portion 121 and making the sliding of the front bracket 11 on the rear bracket 12 more stable.

[0027] The front end portion of the front bracket 11 is fixedly connected to the calender 20, and the rear end portion 111 is slidably connected to the rear bracket 12. When the calender 20 moves back and forth, the front bracket 11 connected between the calender 20 and the rear bracket 12 moves back and forth with the calender 20 through the sliding structure 13, and thus the horizontal distance L can be changed without the need for manual labor and other power equipment to move the bracket 1, with a simple structure and time and labor saving.

[0028] As Figure 5 , 6 shown, a part of the plurality of cooling rollers 2 are rotatably arranged on the front bracket 11, and another part are rotatably arranged on the rear bracket 12. Each cooling roller 2 extends in the left-right direction and rotates around an axis line extending in the left-right direction. Each cooling roller 2 includes a core shaft 21, a roller body 22 coaxially sleeved on the core shaft 21, a bearing 23 coaxially connected between the core shaft 21 and the roller body 22, and a pair of adjusting blocks 24 respectively arranged at both end portions of the core shaft 21. The adjusting block 24 is used to detachably connect both end portions of the core shaft 21 to the bracket 1, facilitating the disassembly and assembly of the cooling roller 2; the roller body 22 can rotate relative to the core shaft 21 around the axis line of the core shaft 21 through the bearing 23 to realize the conveying of the plate. The roller body 22 of the cooling roller 2 on the front bracket 11 forms a first plane in contact with the plate on the front bracket 11, and the roller body 22 of the cooling roller 2 on the rear bracket 12 forms a second plane in contact with the plate on the rear bracket 12. The front end portion 121 of the rear bracket 12 sinks, so that the first plane and the second plane are located in the same conveying plane W (refer to the appendix Figure 3), within which, the conveying plane W is used to carry the plates output by the calender 20. And under the traction of the tractor 30, the plates are pressed against the outer circumferences 22 of a plurality of cooling rollers 2 to be conveyed within the conveying plane W. The remaining heat on the plates is taken away by the plurality of cooling rollers 2 and gradually releases heat during the long-distance conveyance by the bracket 1, thereby achieving a cooling effect.

[0029] Since the plates are relatively soft when output from the calender, in order to prevent the plates from sagging and deforming between adjacent cooling rollers 2 due to their own gravity, the distance between adjacent two cooling rollers 2 is 250 mm - 400 mm. Because the plates gradually dissipate heat and cool and form during the conveyance on the bracket 1, the cooling rollers 2 near the first end 101 of the front bracket 11 are arranged more densely, while the cooling rollers 2 in the latter half of the front bracket 11 and the cooling rollers 2 of the rear bracket 12 are arranged more loosely. The distance between the cooling rollers 2 near the first end 101 of the front bracket 11 is less than the distance between the cooling rollers 2 in the latter half of the front bracket 11 and the distance between the cooling rollers 2 of the rear bracket 12.

[0030] The outer circumferences 22 of the respective cooling rollers 2 are made of aluminum alloy material, and the roller surfaces are anodized to increase the hardness of the outer circumferences 22, making the cooling rollers 2 more durable.

[0031] As Figure 1 、 4 、shown in FIG. 5, a cutting mechanism 40 is mounted on the front bracket 11. The cutting mechanism 40 is used to slice and trim the edges of the plates output by the calender 20, so that the finally output plates meet the production requirements; a platform 3 is disposed adjacent to the cutting mechanism 40. An operator moves to the vicinity of the cutting mechanism 40 through the platform 3 to adjust the position and tilt angle of the cutter on the cutting mechanism 40 in the left-right direction.

[0032] The platform 3 includes a step portion 31 and a platform portion 32. The platform portion 32 is mounted on the upper side of the conveying plane W and is located in front of or behind the cutting mechanism 40; the step portion 31 extends from the platform portion 32 to the ground, for the operator to move from the ground to the upper side of the bracket 1 to adjust the cutting mechanism 40.

[0033] The bracket of the present application is divided into an independent front bracket and a rear bracket. The front bracket is movably arranged between the calender and the rear bracket relative to the rear bracket in the front-rear direction, and can change the distance between the first end and the second end of the bracket to adapt to the front-rear movement of the calender. And the front bracket moves back and forth with the calender. The structure is simple, the operation is convenient, time and labor are saved, and it is convenient for the calender to move back and forth to clean the upstream equipment.

[0034] The foregoing has shown and described the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and what is described in the above embodiments and the specification only illustrates the principles of the present application. Without departing from the spirit and scope of the present application, the present application will have various changes and improvements. The scope of protection claimed by the present application is defined by the appended claims, the specification and their equivalents.
