Description

Technical Field

[0001] This application belongs to the technical field of synchronous pattern alignment extruders, and particularly relates to a cooling mechanism for a synchronous pattern alignment extruder. Background Art

[0002] Synchronous pattern alignment extruders are mainly used for plastic extrusion production, especially in the floor production field, such as the production of products like SPC stone plastic floors and LVT floors. Since the floor contains a large amount of thermoplastic materials, during the floor production process, in order to ensure that the product can have a good shaping effect, after completing steps such as calendaring and laminating, the product generally needs to be cooled to a certain temperature before cutting. In the prior art, the commonly used cooling methods generally include natural wind cooling and water cooling. The natural wind cooling method usually involves setting up a cooling bracket, and the product after calendaring and laminating is transported to the guillotine for shearing through the cooling bracket. Using this method, the final product has a good cooling and shaping effect, but because the cooling efficiency is slow, the length of the cooling bracket that needs to be set is long, resulting in a large floor area for the overall equipment. While using the water cooling method, the cooling effect is good and the overall floor area of the equipment is small, but if a fast cooling effect is desired, the temperature difference between the coolant and the product will be large, which may cause the outer layer of the product to cool rapidly, resulting in a relatively obvious temperature difference between the inside and outside of the product, and ultimately making the cooling effect of the product poor and affecting the final quality of the product. Summary of the Utility Model

[0003] This application aims to solve the technical problems in the prior art that when the cooling mechanism of the synchronous pattern alignment extruder uses natural wind cooling, the floor area is large, and when using water cooling, the cooling effect is poor due to the large temperature difference between the coolant and the product; and proposes a cooling mechanism for a synchronous pattern alignment extruder to effectively reduce the floor area of the equipment while ensuring a good cooling effect.

[0004] To achieve the above object, this application adopts the following technical solutions:

[0005] A cooling mechanism for a synchronous pattern alignment extruder includes a support frame, a first cooling component, a second cooling component, a third cooling component, and a coolant storage device;

[0006] The first cooling component, the second cooling component, and the third cooling component are sequentially arranged on the support frame along the conveying direction of the support frame. The first cooling component, the second cooling component, and the third cooling component are connected in series through pipes. The first cooling component is provided with a liquid outlet, and the liquid outlet is connected to the coolant storage device to transfer the coolant in the first cooling component into the coolant storage device. The third cooling component is provided with a liquid inlet, and the liquid inlet is connected to the coolant storage device. A water pump is arranged between the liquid inlet and the coolant storage device to transfer the coolant in the coolant storage device into the third cooling component.

[0007] Further, the first cooling component and the third cooling component have the same structure, and both include two cooling rollers arranged in parallel. The two cooling rollers are both rotatably connected to the support frame. The two cooling rollers are both of a hollow structure inside, and the opposite ends of the two cooling rollers are respectively connected through pipes. The pipes used to connect the two cooling rollers are rotatably and sealedly connected to the two cooling rollers.

[0008] Further, the second cooling component includes one or more groups of cooling devices, and the structure of the cooling devices is the same as that of the first cooling component and the third cooling component; when the number of the cooling devices is multiple groups, the multiple groups of cooling devices are connected in series through pipes in sequence.

[0009] Further, the liquid outlet is connected to the pipe used to connect the two cooling rollers at one end of the first cooling component.

[0010] Further, the liquid inlet is connected to the pipe used to connect the two cooling rollers at one end of the third cooling component.

[0011] Further, a refrigeration device is arranged inside the coolant storage device to refrigerate the coolant.

[0012] Further, the coolant storage device is a cooling tower.

[0013] Further, the coolant storage device is a cooling tank, and the cooling tank is arranged below the first cooling component, the second cooling component, and the third cooling component.

[0014] Further, the coolant is water.

[0015] The beneficial effects of this application are:

[0016] In this application, the first cooling component, the second cooling component, and the third cooling component connected in series are sequentially arranged on the support frame along the conveying direction of the support frame. The liquid inlet is arranged on the third cooling component, and the liquid outlet is arranged on the first cooling component. During use, the product after extrusion, calendering, and film laminating by the synchronous pattern extrusion machine sequentially passes through the first cooling component, the second cooling component, and the third cooling component for cooling. The coolant in the coolant storage device flows sequentially along the directions of the third cooling component, the second cooling component, and the first cooling component, and finally returns to the coolant storage device for cooling. Thus, the flow direction of the coolant is opposite to the conveying direction of the product, that is, the coolant used to cool the high-temperature product just after calendering and film laminating is the coolant used after passing through the first cooling component and the second cooling component, and the coolant used for the second cooling component is the coolant used after passing through the first cooling component. Furthermore, it can effectively reduce the temperature difference between the cooling component and the product, ensure that the cooling mechanism has a good cooling effect, and at the same time, compared with natural air cooling, it can effectively reduce the floor area of the equipment.

[0027] An embodiment of the present application provides a cooling mechanism for a synchronous pattern extrusion machine, including a support frame 1, a first cooling component, a second cooling component, a third cooling component, and a coolant storage device 2;

[0028] The first cooling component, the second cooling component, and the third cooling component are sequentially arranged on the support frame 1 along the conveying direction of the support frame 1, and the first cooling component, the second cooling component, and the third cooling component are connected in series through pipelines so that the coolant can be sequentially transmitted along the above three groups of cooling components.

[0029] The first cooling component includes two cooling rollers 5 arranged in parallel. Both of the two cooling rollers 5 are rotatably connected to the support frame 1. Both of the two cooling rollers 5 are water-cooling rollers with a hollow interior that are commonly used in the art. The opposite ends of the two cooling rollers 5 are respectively connected through pipelines so that the two cooling rollers 5 are in a parallel state. The pipelines used to connect the two cooling rollers 5 and the two cooling rollers 5 are rotationally sealed. The rotational sealing connection method used is a conventional rotational sealing connection in the art, so it will not be elaborated here. An outlet 3 is provided on the first cooling component. The outlet 3 is arranged at one end of the two cooling rollers 5 and is connected to the corresponding pipelines for connecting the two cooling rollers 5. The outlet 3 is also connected to the coolant storage device 2 to transfer the coolant in the first cooling component (i.e., in the two cooling rollers 5 in the first cooling component) into the coolant storage device 2.

[0030] The second cooling assembly includes twelve sets of cooling devices 6. The twelve sets of cooling devices 6 are connected in series in sequence through pipelines so that the coolant can pass through each set of cooling devices 6 in sequence during use. The structure of the cooling device 6 is the same as that of the first cooling assembly, and both include two cooling rollers 5 arranged in parallel. The two cooling rollers 5 are both rotatably connected to the support frame 1. The two cooling rollers 5 are both water-cooling rollers with a hollow interior that are commonly used in the art. The opposite ends of the two cooling rollers 5 are connected through pipelines respectively to make the two cooling rollers 5 in a parallel state. The pipelines used to connect the two cooling rollers 5 are rotatably and sealingly connected to the two cooling rollers 5. In the actual application process, the specific number of the cooling devices 6 is not limited, and those skilled in the art can set different numbers of cooling devices according to actual cooling needs, which can be one set or multiple sets.

[0031] The structure of the third cooling assembly is also the same as that of the first cooling assembly, and also includes two cooling rollers 5 arranged in parallel. The two cooling rollers 5 are both rotatably connected to the support frame 1. The two cooling rollers 5 are both water-cooling rollers with a hollow interior that are commonly used in the art. The opposite ends of the two cooling rollers 5 are connected through pipelines respectively to make the two cooling rollers 5 in a parallel state. The pipelines used to connect the two cooling rollers 5 are rotatably and sealingly connected to the two cooling rollers 5. An inlet port 4 is provided on the third cooling assembly. The inlet port 4 is arranged at one end of the third cooling assembly and is connected to the corresponding pipeline for connecting the two cooling rollers 5. The inlet port 4 is also connected to the coolant storage device 2. A water pump (not shown in the figure) is provided between the inlet port 4 and the coolant storage device 2 for transporting the coolant in the coolant storage device 2 into the third cooling assembly (i.e., into the two cooling rollers 5 in the third cooling assembly).

[0032] A refrigeration device is provided inside the coolant storage device 2 for refrigerating the coolant. The refrigeration device is a refrigeration device commonly used in the prior art, and its specific structure will not be described in detail. The coolant storage device 2 is a cooling tank, and the cooling tank is arranged below the first cooling assembly, the second cooling assembly, and the third cooling assembly. In the actual application process, the coolant storage device 2 can also be set as a cooling tower according to actual needs.

[0033] In use, the products after extrusion, calendering, and film laminating by the synchronous pattern extrusion machine are sequentially cooled by the first cooling assembly, the second cooling assembly, and the third cooling assembly, while the coolant in the coolant storage device 2 flows sequentially along the directions of the third cooling assembly, the second cooling assembly, and the first cooling assembly and finally returns to the coolant storage device 2 for cooling; thus, the flow direction of the coolant is opposite to the conveying direction of the products, that is, the coolant used to cool the high-temperature products just after calendering and film laminating is the coolant that has passed through the first cooling assembly and the second cooling assembly, and the coolant used for the second cooling assembly is the coolant that has passed through the first cooling assembly. Furthermore, it can effectively reduce the temperature difference between the above cooling assemblies and the products, ensure that the cooling mechanism has a good cooling effect, and at the same time can effectively reduce the floor area of the equipment compared with natural air cooling.

Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the technical solution and its core idea of the present application; those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
