Description

Technical Field

[0001] This utility model relates to the field of cooling equipment for modified polypropylene extruded strips, specifically a novel water-cooling device for modified polypropylene extruded strips. Background Technology

[0002] In the production and processing of polypropylene granules, modified polypropylene is generally extruded into strips, then cooled by water, and finally pelletized. Currently, existing water-cooling devices for modified polypropylene extruded strips mostly rely on workers pulling the extruded strips into various structural parts within the water-cooling tank. This method is inconvenient, inefficient, and the structures supporting the polypropylene extruded strips have fixed installation heights, making it impossible to adjust the strips and limiting the shape they can be shaped to fit into the water. Therefore, to address these issues, a novel water-cooling device for modified polypropylene extruded strips is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a novel water-cooling device for modified polypropylene extrusion strips in order to solve the above-mentioned problems.

[0004] The present invention achieves the above objectives through the following technical solution: a novel water-cooling device for modified polypropylene extrusion strips, comprising a cooling water tank body, wherein cylindrical cylinders are distributed and installed at the bottom of the cooling water tank body, and an electric winding module is installed at one end face of the cooling water tank body, and each cylindrical cylinder is provided with a support bar assembly.

[0005] The support assembly includes a rotating rod, a U-shaped plate, and a cylinder. The cylinder body is fixedly installed inside the cylinder, and the output end of the cylinder is fixedly connected to the middle of the U-shaped plate. Two rotating rods are rotatably installed between the two sides of the U-shaped plate. A take-up strip is inserted between the two rotating rods in the same group, and a traction carrier is installed at one end of the take-up strip. The other end of the take-up strip is wound and connected to an electric take-up module.

[0006] Preferably, a first guide roller, a second guide roller, and a third guide roller are distributed on one side of the interior of the cooling water tank.

[0007] Preferably, the electric winding module consists of a motor, a housing, and an I-beam winding frame located in the housing.

[0008] Preferably, the traction carrier is not limited to one type of structure, and the traction carrier and the external extrusion strip are wrapped together.

[0009] Preferably, the support bar assembly is provided in multiple sets, and the multiple sets of support bar assemblies are in different height states through corresponding cylinders.

[0010] Preferably, the U-shaped plate is always submerged in the water inside the cooling water tank.

[0011] Compared with the prior art, the advantages of this utility model are as follows: It uses a retractable pull strip to pull the traction carrier connected to the end of the polypropylene extrusion strip, and combines the pull strip shuttling through multiple sets of rotating rods to solve the problem of inconvenience in manually operating the polypropylene extrusion strip to shuttle through the cooling water tank. With the multiple sets of cylinders operating alternately in different extension and retraction states, the height between the multiple sets of rotating rods can be adjusted, so that the polypropylene extrusion strip is in a multi-segment zigzag shape, increasing the residence length of the polypropylene extrusion strip in the cold water and ensuring sufficient cooling.

[0020] Please see Figure 1-3 As shown, a novel water-cooling device for modified polypropylene extrusion strips includes a cooling water tank 1. Cylinders 3 are distributed and installed at the bottom of the cooling water tank 1, and an electric winding module 9 is installed at one end face of the cooling water tank 1. Each cylinder 3 is provided with a support strip assembly 2.

[0021] The support assembly 2 includes a rotating rod 210, a U-shaped plate 220, and a cylinder 230. The cylinder body of the cylinder 230 is fixedly installed inside the cylinder 3, and the output end of the cylinder 230 is fixedly connected to the middle of the U-shaped plate 220. Two rotating rods 210 are rotatably installed between the two sides of the U-shaped plate 220. A pull strip 5 is inserted between the two rotating rods 210 in the same group, and a pulling carrier 4 is installed at one end of the pull strip 5. The other end of the pull strip 5 is wound and connected to the electric winding module 9.

[0022] The cooling water tank 1 has a first guide roller 6, a second guide roller 7 and a third guide roller 8 distributed on one side inside to facilitate material feeding.

[0023] The electric winding module 9 consists of a motor, a housing, and an I-beam winding frame located in the housing. The motor enables the electric winding module 9 to wind up the connected winding strip 5.

[0024] The traction carrier 4 is not limited to one type of structure, and the traction carrier 4 is wrapped together with the external extrusion strip.

[0025] The support bar assembly 2 is provided in multiple sets, and the multiple sets of support bar assemblies 2 are in different height states through the corresponding cylinders 230, which is beneficial to adjust the height position of the extruded bar in the cooling water.

[0026] Furthermore, the U-shaped plate 220 is always submerged in the water inside the cooling water tank 1.

[0027] Working principle: When the polypropylene extrusion strip is drawn out, one end of the polypropylene extrusion strip is wrapped around the pulling carrier 4. The electric winding module 9 is operated to wind the connected winding strip 5 at a uniform speed, and the speed is consistent with the extrusion speed. This allows the polypropylene extrusion strip to pass through multiple sets of rotating rods 210 located in the cooling water tank 1 in sequence, completing the task of inserting the polypropylene extrusion strip into the cold water of the cooling water tank 1. Finally, the corresponding cylinders 230 are operated to extend and retract to different degrees, so that the polypropylene extrusion strip is in a multi-segment zigzag shape, increasing the residence length of the polypropylene extrusion strip in the cold water.

[0028] Compared with existing technologies, the difference lies in the following: a retractable pull strip 5 is used to pull the traction carrier 4 connected to the end of the polypropylene extrusion strip. Combined with the pull strip 5 shuttling through multiple sets of rotating rods 210, the problem of inconvenience in manually operating the polypropylene extrusion strip to shuttle through the cooling water tank 1 is solved. The multiple sets of cylinders 230, which are in different extension and retraction states, can adjust the height between the multiple sets of rotating rods 210, so that the polypropylene extrusion strip is in a multi-segment zigzag shape, increasing the residence length of the polypropylene extrusion strip in the cold water and ensuring sufficient cooling.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
