Description

Technical Field

[0001] This invention relates to the field of cooling device technology, specifically to a cooling device for plastic masterbatch molding. Background Technology

[0002] Plastic masterbatch is a plastic processing aid composed of excessive amounts of chemical additives, carrier resin, and dispersants. Masterbatch is an aggregate obtained by uniformly loading excessive amounts of pigments (dyes) into resin. In plastic processing, masterbatch refers to granules produced through a process of mixing various additives and fillers with a small amount of carrier resin for ease of operation, followed by metering, mixing, melting, extrusion, and pelletizing using equipment such as extruders. These granules need to be cooled and molded to form the final masterbatch. However, existing molding cooling devices still have some problems in use, as follows:

[0003] Most existing cooling devices use open or closed cooling water tanks, where particles flow freely and their trajectories are not fixed. This makes them very easy to accumulate in the cooling water tank, which affects the overall cooling effect of the particles. Furthermore, the water flow in existing cooling water tanks cannot carry a large number of continuously fed particles to be cooled, so particles are constantly left in the dead corners at the bottom of the device, which greatly reduces the overall cooling uniformity and effect of the particles. Therefore, we propose a plastic masterbatch molding cooling device. Summary of the Invention

[0016] The present invention has the following beneficial effects:

[0017] 1. This plastic masterbatch molding and cooling device has a material guiding component inside the outer cylinder. The particles to be cooled are fed in from the top feed pipe, and then the feeding particles are centrifugally driven by a rotating distribution plate, causing the particles to flow and continuously fall into the material guiding cooling pipe. The material guiding cooling pipe is also rotating on the distribution plate. With the support of the support component, the distribution plate can rotate on its own axis while revolving around the central axis. In this way, the particles falling into it can fully and evenly exchange heat with the cooling water under the action of rotation. The slender material guiding cooling pipe allows the particles to fall in small amounts and in sequence, preventing dead corners inside the equipment from accumulating and avoiding particle blockage.

[0018] 2. This plastic masterbatch molding and cooling device has a stretchable and movable support ring and bottom ring at the bottom of the inner cylinder. The rotation of the first motor pulls them upward, so that the particles falling from the cooling pipe to the bottom are cooled and then lifted to the top by the support ring for discharge. During the upward lifting process, the elastic band at the bottom ensures that the particles in the middle of the collection plate do not spread to the bottom edge of the inner cylinder, ensuring that the particles can be collected again after the support ring moves down again, thus ensuring the continuous use of the entire device.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The plastic masterbatch molding and cooling device involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-3 A plastic masterbatch molding cooling device includes an outer cylinder 1 filled with cooling water, an inner cylinder 2 fixedly installed inside the outer cylinder 1, a material guiding assembly 3 movably installed on the inner cylinder 2, a water inlet pipe 4 fixedly installed at the bottom center of the outer cylinder 1, a drain pipe 5 fixedly connected through the upper side of the outer cylinder 1, a filter screen structure provided above the inner cylinder 2, and the height of the filter screen is not higher than the height of the drain pipe 5, a collection trough 6 fixedly installed on the upper outer side of the outer cylinder 1, a support assembly 7 fixedly installed inside the inner cylinder 2, a lifting and discharging assembly 8 installed on the inner cylinder 2, a discharge trough 9 opened at the top of the outer cylinder 1, a bracket 10 fixedly installed at the top of the inner cylinder 2, a second motor 11 fixedly installed on the bracket 10, a drive gear 12 fixedly installed on the output shaft of the second motor 11, and a side groove 13 opened on the inner side of the outer cylinder 1.

[0031] Compared with the prior art, this application provides a material guiding component 3 inside the outer cylinder 1. The particles to be cooled are fed in through the top feed pipe 31, and then centrifugally rotated by the rotating distribution plate 32, causing the particles to flow within it and continuously fall into the material guiding cooling pipe 34. The material guiding cooling pipe 34 is rotatably mounted on the distribution plate 32. Supported by the support component 7, the distribution plate 32 rotates on its own axis while simultaneously revolving around the central axis. This allows the particles falling into the cooling pipe to fully and evenly exchange heat with the cooling water under the action of rotation. The slender material guiding cooling pipe 34 ensures that the particles... The particles fall in small quantities and in sequence, preventing accumulation in dead corners inside the equipment and avoiding particle blockage. At the same time, by setting a stretchable and movable support ring 84 and bottom ring 85 at the bottom of the inner cylinder 1, the rotation of the first motor 82 pulls them upward, so that the particles falling from the guide cooling pipe 34 to the bottom are cooled and then lifted to the top by the support ring 84 for discharge. During the upward lifting process, the elastic band 86 at the bottom ensures that the particles in the middle located on the collection plate 35 do not spread to the edge of the bottom of the inner cylinder 1, ensuring that the particles can be collected again after the support ring 84 moves down again, ensuring the continuous use effect of the entire device.

[0032] Please see Figure 1-4 A plastic masterbatch molding and cooling device includes a material guiding assembly 3, which includes a feed pipe 31. A distribution plate 32 is fixedly installed at the bottom end of the feed pipe 31. A core rod 33 is fixedly installed on the lower surface of the distribution plate 32. A material guiding and cooling pipe 34 is movably installed on the distribution plate 32. A collection plate 35 is fixedly installed at the bottom end of the core rod 33. A driven tooth 36 is sleeved and fixedly installed on the feed pipe 31.

[0033] In this embodiment, it should be noted that the top end of the feed pipe 31 is connected to an external feeding device, and a slot is opened at the end of the feed pipe 31 connected to the distribution plate 32. Circular grooves are evenly opened on the distribution plate 32. The top end of the guide cooling pipe 34 is located in the circular groove and rotates. A discharge groove is opened at the bottom end of the guide cooling pipe 34. A water inlet groove is opened at the end of the core rod 33 connected to the collecting plate 35. The driven gear 36 meshes with the driving gear 12. In this way, after the particles to be cooled enter the upper surface of the distribution plate 32 through the feed pipe 31, the rotation of the driving gear 12 drives the feed pipe 31 to rotate. The rotation of the distribution plate 32 causes the particles to move centrifugally on the upper surface of the distribution plate 32 under the action of centrifugal force. This allows the particles to fall evenly from the top of each guide cooling pipe 34 into the plate. The particles also rotate simultaneously, which greatly improves the uniformity of heat exchange with the internal cooling water and enhances the cooling effect of the plastic masterbatch. It also prevents the masterbatch from piling up. When the masterbatch is cooled and falls into the collection plate 35 at the bottom, it can spread to the lifting and discharge assembly 8 with the help of its rotation, making it easier to lift and discharge it later.

[0034] Please see Figure 2-5 A plastic masterbatch molding and cooling device includes a support assembly 7, the support assembly 7 includes a bottom rod 71, a support rod 72 is uniformly fixedly installed on the upper surface of the bottom rod 71, and a support ring 73 is fixedly installed on the top end of the support rod 72.

[0035] In this embodiment, it should be noted that a through groove is provided at the bottom of the inner cylinder 2, and one end of the bottom rod 71 is fixedly connected to the top of the through groove of the inner cylinder 2. The support ring 73 is arranged in a ring around the outer edge of the material guiding cooling pipe 34. In this way, when the material distribution plate 32 drives the material guiding cooling pipe 34 to rotate, the support ring 73 can better support the rotation of the material guiding cooling pipe 34, thereby comprehensively cooling the plastic masterbatch flowing inside and ensuring the cooling effect of the entire device.

[0036] Please see Figure 1-7 A plastic masterbatch molding and cooling device includes a lifting and discharging assembly 8. The lifting and discharging assembly 8 includes a support 81. A first motor 82 is fixedly installed on one side of the support 81. A rotating wheel is movably installed inside the support 81. A pull rope 83 is movably installed on the rotating wheel of the support 81. A support ring 84 is fixedly installed at the bottom end of the pull rope 83. A bottom ring 85 is movably provided at the bottom end of the support ring 84. An elastic band 86 is fixedly installed below the bottom ring 85. Locking insert structures 87 are movably installed on both sides inside the support ring 84. A sliding pin 88 and a locking component structure 89 are fixedly installed on both sides of the upper surface of the bottom ring 85.

[0037] In this embodiment, it should be noted that a water-draining groove is provided on the support ring 84. The inner ring of the support ring 84 is set to be higher than the outer ring. The elastic band 86 is fixedly installed at the bottom end of the inner ring of the bottom ring 85, and the bottom end of the elastic band 86 is fixedly connected to the bottom end of the inner cylinder 1. The locking plug structure 87 is slidably limited at the location of the side groove 13. The top of the side groove 13 is provided with a slope structure, and the height of the slope structure is higher than the top of the through groove opened at the bottom end of the inner cylinder 2. A fixing slot is provided on the outer side of the inner cylinder 2 above the through groove. The fixing slot can be engaged with the locking component structure 89. The sliding pin 88 and the locking component structure 89 are respectively movably set inside the support ring 84. The locking component structure 89 is movably engaged with the locking plug structure 87 and slidably set. After the cooled masterbatch accumulates on the support ring 84, the elastic band 86 stretches and grows as the support ring 84 moves upward, gradually sealing the through groove at the bottom of the inner cylinder 2. This prevents the plastic masterbatch in the middle of the outer cylinder 1 from spreading to the edge after the support ring 84 moves upward. When it moves above the through groove at the bottom of the inner cylinder 2, it engages with the fixing slot, ensuring that the bottom ring 85 is positioned above the through groove. This ensures that the elastic band 86 completely covers the area, preventing the spread of the plastic masterbatch. Under the driving action of the side groove 13, the bottom ring 85 separates from the support ring 84, and the locking plug structure 87 separates from the locking component structure 89. This also facilitates the reconnection of the locking plug structure 87 and the locking component structure 89 during the subsequent downward movement, ensuring the cyclical use effect of the entire device.

[0038] Please see Figure 6-9 A plastic masterbatch molding and cooling device includes a locking insert structure 87, which includes an insert plate 871. An inner groove 872 is provided on one side of the insert plate 871. An inner plate 873 is fixedly installed below the middle of the inner groove 872. A limit straight groove 874 is provided in the middle of the inner plate 873. An elastic telescopic rod 875 is fixedly installed at one end of the insert plate 871. Springs 876 are fixedly installed on both sides of one end of the insert plate 871.

[0039] In this embodiment, it should be noted that the insert plate 871 is slidably disposed inside the support ring 84, the sliding pin 88 has a T-shaped structure and is slidably disposed in the inner groove 872 through the limiting straight groove 874, one end of the elastic telescopic rod 875 is movably disposed against the locking member structure 89, and one end of the spring 876 is fixedly installed inside the support ring 84. In this way, the side groove 13 can drive the insert plate 871 to move to one side during the upward movement. This process compresses the elastic telescopic rod 875 and the spring 876 at the same time, which will push the locking member structure 89 until it is locked into the fixed slot for fixed support, thereby ensuring that the bottom elastic band 86 can be stably sealed and preventing the plastic masterbatch from spreading.

[0040] Please see Figure 7-8A plastic masterbatch molding and cooling device includes a locking structure 89, the locking structure 89 includes a base 891, a slot 892 is provided above the base 891, and a sliding plug 893 is movably installed on one side of the base 891.

[0041] In this embodiment, it should be noted that the bottom end of the base 891 is fixedly installed on the upper surface of the bottom ring 85. The slot 892 is divided into two sections, with the opening width of the end near the sliding pin 88 being smaller than the width of the other end. The elastic telescopic rod 875 is movably inserted into the slot 892, and the smaller opening width of the slot 892 is the same as the middle section size of the elastic telescopic rod 875. The sliding plug 893 is movably inserted into the slot 892 via a plug rod. In this way, the elastic telescopic rod 875 is driven by the side groove 13 to push the sliding... When the movable plug 893 extends outward, and after the slot 892 moves and is inserted into the fixed slot, the elastic telescopic rod 875 moves laterally in the slot 892, causing the widest part of the elastic telescopic rod 875 to move out of the narrowest part of the slot 892 opening, thus disengaging the elastic telescopic rod 875 from the slot 892. At the same time, the sliding pin 88 also moves relative to the end without the inner plate 873 in the inner groove 872 and separates from it, thus releasing the bottom ring 85 and ensuring the overall conveying path of the plastic masterbatch.

[0042] The working principle is as follows: the plastic masterbatch to be cooled is conveyed from the feed pipe 31 to the surface of the distribution plate 32. The second motor 11 is started to drive the support 10 to rotate, which in turn drives the guide assembly 3 to rotate as a whole through the driven gear 36. During the rotation, the plastic masterbatch is dispersed on the surface of the distribution plate 32 and falls into the guide cooling pipe 34. While the distribution plate 32 drives the guide cooling pipe 34 to rotate, the guide cooling pipe 34 also rotates under the action of the support ring 73, which makes the plastic masterbatch and cooling water inside fully mix and exchange heat. Cooling water flows into the outer cylinder 1 through the bottom water inlet pipe 4. The cooling water flows from bottom to top in the outer cylinder 1, so that the upper cooling water is at the temperature after heat exchange with the lower plastic masterbatch. The upper cooling water is set in a direction opposite to the movement of the plastic masterbatch to ensure that the overall internal temperature is roughly the same, avoiding cracking or poor cooling effect of the plastic masterbatch due to excessive temperature difference. After cooling, the plastic masterbatch is cooled by the rotation of the collection plate 35. The masterbatch flows to the upper surface of the support ring 84, which in turn drives the pull rope 83 via the first motor 82 to pull the support ring 84 and the bottom ring 85 upward. During the movement, the elastic band 86 at the bottom is stretched to seal the bottom end of the inner cylinder 2. Driven by the side groove 13, the insert plate 871 is pushed to compress the elastic telescopic rod 875, which in turn pushes the sliding insert 893 to the fixed slot position for insertion. After insertion, the sliding pin 88 also disengages from the inner groove 872. This achieves the connection between the bottom ring 85 and its structure and the support ring 84. The end separation ensures that the cooled plastic masterbatch can be discharged when it is lifted to the position of the discharge trough 9 during the upward movement of the support ring 84. Then, under its own weight, the support ring 84 falls back to the position of the locking structure 89, so that the elastic telescopic rod 875 is re-engaged into the slot 892. During the subsequent downward movement, the elastic force causes the insert plate 871 to move back to the position of the side groove 13, thereby unlocking the locking and fixing of the support ring 84, so as to continue to collect the cooled plastic masterbatch.

[0043] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
