Description

Technical Field

[0001] This utility model relates to the field of plastic granule production technology, specifically to a water-cooling device for HDPE plastic granule production. Background Technology

[0002] Water cooling is required during the production of plastic products. After the plastic raw material is melted, it enters the extruder and is then extruded into long strips which are discharged into a water tank for water cooling, thus obtaining a long strip of plastic with a stable shape. This process is called water cooling and is an indispensable part of the entire production process.

[0003] A search revealed a water-cooling device for the production of modified plastic granules, with publication number CN219055288U. This device includes a base with a cooling water tank fixed to the top. It addresses the problem that water carried on the surface of long strips of plastic after they are removed from the water tank easily drips onto the workshop floor. However, when water-cooling multiple long strips of plastic, the plastic tends to become entangled and mixed inside the device due to water flow impact or plastic movement, affecting the quality of the plastic product. Therefore, we propose a water-cooling device for the production of HDPE plastic granules. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This invention improves the water-cooling apparatus provided herein for the production of HDPE plastic granules. Please refer to [link / reference needed]. Figures 1-3The system includes: a cooling tank 1, a circulating water cooling tank 2 at one end of the cooling tank 1, a rotating roller 3 passing through the inner side of the circulating water cooling tank 2 via a sealed bearing, a first motor 4 bolted to one side of the outer wall of the cooling tank 1, and the output shaft of the first motor 4 connected to one end of the rotating roller 3, a traction shaft 5 fixed to the outer wall of the end of the rotating roller 3 away from the first motor 4, a transmission belt 6 sleeved on the outer wall of the traction shaft 5, support plates 7 symmetrically fixed to the inner surface of the rotating roller 3, a through groove 8 formed on the outer wall of the support plate 7, an insertion hole 9 formed on the lower inner surface of the through groove 8, and a guide groove 901 at the uppermost end of the insertion hole 9. The lower end is connected to a cylindrical rotating groove 902. A slot 903 is provided at the connection between the guide groove 901 and the rotating groove 902. A spring hole 904 is provided at the lowest end of the insertion hole 9. A baffle 10 is connected to the through groove 8 through the insertion hole 9. The baffle 10 forms a detachable structure with the support plate 7 through the insertion hole 9 and the through groove 8. A plate body 1001 is provided at the upper end of the baffle 10. An insertion rod 1002 is fixed to the lower surface of the middle part of the plate body 1001. A locking block 1003 is symmetrically fixed to the lower outer wall of the insertion rod 1002. A spring post 1004 is connected to the lower outer wall of the insertion rod 1002. The insertion rod 1002 and the locking block 1003 are connected to the support plate 7. The guide groove 901 has a matching external structure, and the insertion rod 1002 and the locking block 1003 can be inserted into the guide groove 901 due to their matching structures. The insertion rod 1002 is rotatably connected to the insertion hole 9 via the locking block 1003 and the rotating groove 902. When the locking block 1003 moves to the inside of the rotating groove 902, it can rotate and adjust within the cylindrical rotating groove 902. The insertion rod 1002 is elastically telescopically connected to the insertion hole 9 via the guide groove 901, the spring post 1004, and the spring hole 904. The insertion rod 1002 is also connected to the insertion hole 9 via the locking block 1003 and the locking groove 903. The baffle 10 is connected by the engagement of the locking block 1003 with the locking groove 903 and the pressing of the spring column 1004 against the insertion rod 1002 in the spring hole 904, which allows the baffle 10 to be quickly installed and removed inside the through groove 8. The through groove 8 is used to guide the long plastic strips through it to move from the support plate 7 of the rotating roller 3 to the other end of the device. Whether the through groove 8 is open can be controlled by the easily detachable baffle 10, so that when the water cooling device transports and cools the long plastic strips through the rotating roller 3, multiple long plastic strips are not easily mixed and entangled due to the impact of the water flow or the rotation of the rotating roller 3, thus improving the stability of operation.

[0022] Please see Figure 1The water cooling device for HDPE plastic granule production includes: an inlet 11 is provided on the upper surface of the cooling tank 1 near the circulating water cooling tank 2, and an inclined partition 12 is provided at the other end of the circulating water cooling tank 2. The inner lower surface of the inlet 11 and the top outer wall of the partition 12 are both equipped with rollers 13 through bearings, and the rollers 13 are rotatably connected to the inlet 11 and the partition 12. The rollers 13 installed at the inlet 11 and the partition 12 are used to assist the movement of long strips of plastic produced, reduce friction damage between the plastic and the device during the water cooling operation, and improve the smoothness of the plastic products when moving.

[0023] Please see Figure 1 The water cooling device for HDPE plastic granule production includes: a drain trough 14 at the other end of the cooling tank 1; a second motor 15 is bolted to one outer wall of the drain trough 14; the output shaft of the second motor 15 is connected to a hollow rotating cage 16; the rotating cage 16 passes through the inner side of the drain trough 14 through a sealed bearing; the rotating cage 16 is rotatably connected to the drain trough 14 through the output shaft of the second motor 15; and the rotating cage 16 rotates in the same direction as the rotating roller 3. The rotating cage 16 is used to assist the plastic products passing through the drain trough 14 in draining operations, reducing the water carried by the plastic products when they leave the water cooling device, reducing the pollution of the production environment by the cooling water, and collecting the cooling water in the drain trough 14.

[0024] Working Principle: For this type of water-cooling device used in the production of HDPE plastic granules, the operator first places the cooling tank 1 on a stable, level working surface, with the inlet 11 of the cooling tank 1 facing the output position of the plastic strips. Then, the operator connects the water source to the circulating water-cooling tank 2, allowing the tank to continuously cool the plastic strips with cooler water. Next, the first motor 4 and the second motor 15 are started and stopped manually by the operator. The rotation direction and linear speed of the rollers 3 and the rotating cage 16 driven by the output shafts of the first motors 4 and 15 are kept consistent to prevent damage to the produced plastic products. The rollers 3 rotate synchronously through the power transmission of the traction shaft 5 and the transmission belt 6. Then, the operator removes and installs the baffle 10 on the support plate 7 of the rollers 3 according to the required number of plastic strips to be cooled. The baffle 10 is accessed by the operator pressing down on the plate 1001 and the insert rod 1002, allowing the insert rod 1002 and the locking block 1003 to pass through. The rod 1002 enters the insertion hole 9 of the through slot 8 through the guide groove 901. When the spring post 1004 at the bottom of the insertion rod 1002 enters the inner side of the spring hole 904, the operator continues to press down, compressing the spring to make the locking block 1003 enter the inner side of the rotating groove 902. After the locking block 1003 rotates inside the rotating groove 902 and matches the locking slot 903, the operator releases the plate 1001, so that the locking block 1003 is locked into the locking slot 903 under the elastic force of the spring post 1004, so that the baffle 10 can block the through slot 8 and make the cooling water flow as open as possible. The plastic strips flow in the through-groove 8. Then, when multiple plastic strips move to the inside of the circulating water cooling tank 2 through the roller 13 of the inlet 11, the plastic strips move to the drain tank 14 through the open through-groove 8. The multiple plastic strips are separated by the through-groove 8, so they are not easy to get tangled due to water flow impact or collision, which has little impact on the quality of the finished plastic products. Finally, after the plastic strips leave the circulating water cooling tank 2 through the roller 13 on the partition 12, they are driven by the drain tank 14 to shed water, which makes it easier for the drain tank 14 to collect water and reduce environmental pollution.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
