Description

Technical Field

[0001] The utility model belongs to the technical field of sheet material cooling, and more specifically relates to a cooling device for sheet material production. Background Art

[0002] The existing polymer sheet production line in China does not have a cooling device that can produce wide soft sheets. The existing cooling device is only suitable for producing hard sheets, but difficult to produce soft sheets. The existing cooling device has two parts: a calender and a cooling bracket. The calender needs to be moved during the production process to get closer to or farther away from the extruder for sheet production to adapt to adjustments in the production process; therefore, the distance between the calender and the cooling bracket is variable. When producing hard sheets, such a change in distance has little effect on the hard sheets, but when producing soft sheets, such a change in distance causes the distance between the soft sheet just out of the calender and the cooling bracket to change. When the distance is large, the soft sheet is suspended for a large distance, which affects the quality of the soft sheet due to tension. Utility Model Content

[0003] The utility model aims to provide a cooling device for sheet material production in view of the deficiencies in the prior art, so as to solve the problem that the cooling device in the prior art is difficult to be applied to the cooling demand in the production process of soft sheets.

[0025] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0026] like Figures 1 to 3 As shown, the utility model provides a cooling device for sheet production, comprising:

[0027] A calender 1, the calender 1 comprising at least two calender rollers 2;

[0028] a first cooling bracket 3, the first cooling bracket 3 is integrally connected to the calender 1, and an input end of the first cooling bracket 3 is close to an output end of the calender 1;

[0029] The driving mechanism 4 is connected to the calender 1 and is used to drive the calender 1 and the first cooling bracket 3 to move.

[0030] Specifically, in order to solve the problem that the cooling devices in the prior art are difficult to adapt to the cooling needs in the production process of soft sheets, the cooling device for sheet production provided by the utility model has an integrally connected calender 1 and a first cooling bracket 3. When the driving mechanism 4 drives the calender 1 to move, it can synchronously drive the first cooling bracket 3 to move, so that when the calender 1 moves, the distance between the output end of the calender 1 and the input end of the first cooling bracket 3 remains unchanged, and the distance will not be too large, thereby reducing the degree of overhead of the sheet and avoiding the situation that the production quality of the soft sheet is difficult to ensure due to tension.

[0031] Optionally, it also includes a second cooling bracket 5, which is fixed on the ground, and the output end of the first cooling bracket 3 is slidably connected to the input end of the second cooling bracket 5, and the driving mechanism 4 can drive the calender 1 and the first cooling bracket 3 to move toward or away from the second cooling bracket 5.

[0032] Specifically, the second cooling bracket 5 is a fixed structure fixed on the ground. In order to achieve the connection with the first cooling bracket 3, the output end of the first cooling bracket 3 is slidably connected with the input end of the second cooling bracket 5. In this way, when the first cooling bracket 3 moves with the calender 1, the connection between the first cooling bracket 3 and the second cooling bracket 5 can still be maintained, thereby enabling continuous cooling.

[0033] Optionally, at least two calender rollers 2 are arranged in sequence from bottom to top.

[0034] In this embodiment, three calender rollers 2 are provided, namely a lower roller, a middle roller and an upper roller.

[0035] Optionally, a feed roller 6 is provided between the calender roller 2 near the output end of the calender 1 and the input end of the first cooling bracket 3 .

[0036] Specifically, the input end of the first cooling bracket 3 is located on the side of the calender 1, such as the left or right side, and the feed roller 6 is located between the input end of the first cooling bracket 3 and the uppermost calender roller 2, and the feed roller 6 can play a role in guiding the material.

[0037] Optionally, an active cooling roller 7 is provided between the calender roller 2 near the output end of the calender 1 and the input end of the first cooling bracket 3 .

[0038] Specifically, an active cooling roller 7 is provided between the input end of the first cooling bracket 3 and the uppermost calendering roller 2. The active cooling function provided by the active cooling roller 7 can cool the sheet in advance, which is very beneficial to ensuring the production quality of the soft sheet and can reduce the deformation of the soft sheet during the production process.

[0039] In this embodiment, the active cooling roller 7 is arranged downstream of the feed roller 6, and the sheet bypasses the calendering roller 2, the feed roller 6, the active cooling roller 7 in sequence and is conveyed to the first cooling bracket 3. The feed roller 6 and the active cooling roller 7 can form a support for the sheet between the input end of the first cooling bracket 3 and the top calendering roller 2 of the calender 1.

[0040] Optionally, the first cooling bracket 3 includes a first shell and a plurality of first cooling rollers arranged in the first shell, and the first shell is cantilevered.

[0041] Specifically, a plurality of first cooling rollers are rotatably disposed in the first shell and are used to support and transport the sheet. One end of the first shell is integrally connected to the calender 1 , and the other end of the first shell forms a cantilever end that can be overlapped on the second cooling bracket 5 .

[0042] Optionally, the second cooling bracket 5 includes a second outer shell and a plurality of second cooling rollers arranged in the second outer shell, and a support foot 8 is arranged below the second outer shell.

[0043] Specifically, the second shell of the second cooling bracket 5 is supported and fixed on the ground by the supporting feet 8, and a plurality of second cooling rollers are rotatably disposed in the second shell and are used to support and transport the sheets.

[0044] Optionally, a roller 9 is provided on the lower side of one end of the first shell close to the output end of the first cooling bracket 3 , and the roller 9 rolls with the input end of the second cooling bracket 5 to achieve a sliding connection between the first cooling bracket 3 and the second cooling bracket 5 .

[0045] Specifically, by disposing the roller 9 on the lower side of the first shell, the movement of the first cooling bracket 3 relative to the second cooling bracket 5 and the connection therebetween are achieved, so that the sheet can be continuously conveyed and cooled.

[0046] Optionally, a connecting support plate 10 is provided at one end of the second shell close to the input end of the second cooling bracket 5 , and the connecting support plate 10 supports the roller 9 .

[0047] Specifically, the connecting support plate 10 supports the roller 9 , and the roller 9 can roll on the upper side of the connecting support plate 10 as the first cooling bracket 3 moves.

[0048] In this embodiment, the connecting support plate 10 is a bent plate, and one end of the connecting support plate 10 that cooperates with the roller 9 is sunken so that the supporting surfaces of the first cooling bracket 3 and the second cooling bracket 5 are as coplanar as possible.

[0049] Optionally, the linear speeds of the calender roll 2, the feed roll 6 and the active cooling roll 7 are the same.

[0050] Specifically, the calendering roller 2, the feed roller 6 and the active cooling roller 7 can be adjusted in a linkage manner and regulated by a frequency converter so that the linear speeds on the roller surfaces of the calendering roller 2, the feed roller 6 and the active cooling roller 7 are the same, thereby avoiding excessive tension when transmitting the sheet.

[0051] In this embodiment, a slide rail is provided on the ground, and the calender 1 slides with the slide rail and can move. The driving mechanism 4 includes a driving motor and a chain transmission mechanism. The driving motor is connected to the calender 1 through the chain transmission mechanism. Since the first cooling bracket 3 is integrally connected to the calender 1, the first cooling bracket 3 can move with the calender 1. The motor pulls the chain of the chain transmission mechanism, and the chain rotates counterclockwise. The upper part of the chain is connected to the calender 1 through a connecting component. As the chain moves, the calender 1 can be driven to move to the left. Conversely, when the chain rotates clockwise, the calender 1 moves to the right, thereby driving the overall structure of the calender 1 and the first cooling bracket 3 to move left and right on the slide rail.

[0052] In summary, when the cooling device for sheet material production provided by the utility model is used, the production of a soft sheet material for waterproof coiled material is taken as an example: the cooling device for sheet material production is arranged downstream of the extruder, and the polymer raw material is extruded and formed by the screw extruder and its mold, and the high-temperature sheet material enters between the lower roller and the middle roller, goes up around the middle roller, passes through the upper roller, and is then transported by the feed roller 6 and the active cooling roller 7. The linear speeds of the five rollers are consistent, which can ensure that the sheet material has a constant tension before it is completely cooled, and no indirect large traction force is generated; in order to adapt to the adjustment in the production process, the calender 1 moves under the driving action of the drive mechanism 4 , close to or away from the extruder, and correspondingly away from or close to the second cooling bracket 5. Since the first cooling bracket 3 is integrally connected to the calender 1, the first cooling bracket 3 can move with the calender 1. Therefore, the distance between the output end of the calender 1 and the input end of the first cooling bracket 3 remains unchanged and is always maintained at an acceptable distance, thereby achieving precise control of the distance between the sheet and the cooling bracket. In order to achieve docking with the second cooling bracket 5, the first cooling bracket 3 and the second cooling bracket 5 adopt a roller 9-type connection method, thereby achieving a sliding connection between the two, thereby forming continuous transportation and cooling of the sheet.

[0053] The various embodiments of the utility model have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
