Abstract
Description
Technical Field
[0001] This utility model relates to the field of modified plastics technology, and in particular to a cooling device for modified plastic filler masterbatch particles. Background Technology
[0002] Modified plastic filler masterbatch granules are granular materials made by mixing fillers (such as calcium carbonate, talc, barium sulfate, etc.), carrier resins (such as polyethylene PE, polypropylene PP) and additives (dispersants, lubricants, stabilizers, etc.). The core of this product is to reduce costs by using a high proportion of fillers, while optimizing processing performance and finished product characteristics by using carrier resins and additives.
[0003] A search revealed Chinese Patent Publication No. CN220280173U, which discloses a cooling device for modified plastic filler masterbatch granules. The device includes a cooling box assembly, a discharge assembly, and a worktable. The cooling box assembly is located above the discharge assembly, which is located above the worktable. A discharge pipe is fixedly connected to the bottom of the worktable. This technical solution uses a coiled pipe to divert and cool the modified plastic filler masterbatch granules, improving the cooling effect. However, this structure is prone to clogging in the coiled pipe, hindering flow and affecting continuous production. Furthermore, the cooled granules easily generate debris, but the device lacks a screening structure, making it impossible to effectively separate debris from qualified granules, thus failing to meet usage requirements. Therefore, this paper proposes a cooling device for modified plastic filler masterbatch granules to address the aforementioned problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a modified plastic filler masterbatch granule cooling device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A modified plastic filler masterbatch granule cooling device includes a support frame, a cooling box at the top of the support frame, a material bucket extending through the top of the cooling box and to the bottom of the support frame inside the cooling box, a feed pipe at the top of the material bucket, a rotating mechanism extending into the material bucket and through to the bottom of the material bucket at the top of the material bucket, and a screening component communicating with the material bucket at the bottom of the support frame, with a movable mechanism extending outward from the screening component inside the screening component.
[0007] The rotating mechanism includes a rotating cylinder, which is rotatably mounted on the top of the material barrel and extends to its bottom. Rotary joints are fixedly connected to both the upper and lower ends of the rotating cylinder. A protective frame is provided on the top of the material barrel, located outside the rotating cylinder. A drive motor is fixedly installed inside the protective frame. Bevel gears are fixedly installed on the output shaft of the drive motor and on the outside of the rotating cylinder. The two bevel gears mesh with each other. Bending stirring rods communicating with the interior of the rotating cylinder are fixedly installed on both the left and right sides of the rotating cylinder.
[0008] Preferably, the screening assembly includes a connecting frame, which is fixedly installed at the bottom of the support frame. A guide hopper communicating with the material bucket is fixedly installed on the inner side of the connecting frame, and a collection frame communicating with the bottom of the guide hopper is fixedly installed on the inner side of the connecting frame. A collection box extending to its front side is movably installed inside the collection frame.
[0009] Preferably, the movable mechanism includes a screening plate, which is movably installed inside the guide hopper and extends through to the left side of the connecting frame. Two support blocks are fixedly installed on both the left and right sides of the inner wall of the guide hopper and located below the screening plate. A vibration motor is fixedly installed at the bottom of the screening plate. A support rod is movably installed inside the support block, extending through to its top and fixedly connected to the screening plate. A support plate located inside the support block is fixedly connected to the bottom of the support rod. A support spring is fixedly installed at the bottom of the support plate.
[0010] Preferably, water pipes communicating with the interior are fixedly installed on both the upper and lower sides of the cooling box, and flow holes are opened inside both the rotating cylinder and the bent stirring rod.
[0011] Preferably, the top of the feed hopper is connected to a receiving pipe that communicates with the material bucket, and a handle is fixedly installed on the front side of the collection box.
[0012] Preferably, the screening plate is designed with an inclined structure, and the sides of the connecting frame and the guide hopper are provided with through holes that are adapted to the moving trajectory of the screening plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This modified plastic filler masterbatch granule cooling device significantly improves the cooling efficiency and uniformity of the modified plastic filler masterbatch granules through the synergistic effect of the rotating mechanism and the cooling tank. The drive motor drives the rotating cylinder to rotate through the bevel gear, which in turn drives the bent stirring rod to rotate synchronously, thoroughly stirring the granules in the material tank. At the same time, the water pipes on the upper and lower sides of the cooling tank introduce cooling medium (such as cold water), which circulates in the material tank through the flow holes inside the rotating cylinder and the bent stirring rod, making full contact with the granules to achieve efficient heat exchange, avoid local overcooling or overheating, ensure uniform granule cooling, and improve product quality.
[0015] This modified plastic filler masterbatch granule cooling device effectively improves the quality and convenience of granule discharge by combining the screening components with the moving mechanism. The screening plate adopts an inclined structure design, and with the cooperation of the vibration motor, the screening plate is driven to vibrate through the support rod, support plate and support spring, which can quickly separate qualified particles from the debris generated by cooling friction. The structural design of the support block and support spring not only limits the vibration trajectory of the screening plate (adapted by the through holes on the side of the connecting frame and the guide hopper), but also effectively helps users to remove debris from the modified plastic filler masterbatch granules and improve the granule quality.

[0026] Example
[0027] like Figure 1-5 As shown, this utility model provides a technical solution: a modified plastic filler masterbatch granule cooling device, including a support frame 1, which serves as the base support structure of the entire device. A cooling box 2 is fixedly installed on the top of the support frame 1. Water pipes 21 communicating with the interior of the cooling box 2 are fixedly installed on both the upper and lower sides of the cooling box 2. A material bucket 3, which extends through the top of the cooling box 2 and extends to the bottom of the support frame 1, is fixedly installed inside the cooling box 2. The water pipes 21 on the upper and lower sides of the cooling box 2 are respectively connected to an external cooling medium circulation system (such as a chiller unit). By introducing a low-temperature cooling medium (such as cold water) into the cooling box 3, uniform cooling of the modified plastic filler masterbatch granules inside the material bucket 3 is achieved. A feed pipe 4 is fixedly installed on the top of the material bucket 3 for stably introducing the modified plastic filler masterbatch granules to be cooled into the material bucket 3.
[0028] A rotating mechanism 5 is movably installed on the top of the material tank 3, extending into its interior and penetrating to its bottom. The rotating mechanism 5 includes a rotating cylinder 51, which is rotatably installed on the top of the material tank 3 and extends to its bottom. Rotary joints 52 are fixedly connected to both the upper and lower ends of the rotating cylinder 51. A protective frame 53 is provided on the top of the material tank 3, located outside the rotating cylinder 51. A drive motor 54 is fixedly installed inside the protective frame 53. Bevel gears 55 are fixedly installed on the output shaft of the drive motor 54 and on the outer side of the rotating cylinder 51, meshing with each other. Bent stirring rods 56, communicating with the interior of the rotating cylinder 51, are fixedly installed on both the left and right sides of the rotating cylinder 51. Flow holes are provided inside both the rotating cylinder 51 and the bent stirring rods 56. The bent structure of the stirring rod 56 increases the contact area with the particles. This modified plastic filler masterbatch particle cooling device, through the synergistic effect of the rotating mechanism 5 and the cooling tank 2, significantly improves the cooling efficiency and uniformity of the modified plastic filler masterbatch particles. The drive motor 54 drives the rotating cylinder 51 to rotate through the bevel gear 55, which drives the bent stirring rod 56 to rotate synchronously, fully stirring the particles in the material tank 3. At the same time, the water pipes 21 on the upper and lower sides of the cooling tank 2 introduce cooling medium (such as cold water). The cooling medium circulates in the material tank 3 through the flow holes inside the rotating cylinder 51 and the bent stirring rod 56, making full contact with the particles to achieve efficient heat exchange, avoid local overcooling or overheating, ensure uniform particle cooling, and improve product quality.
[0029] The bottom of the support frame 1 is fixedly connected to a screening component 6 that communicates with the material bucket 3. The screening component 6 includes a connecting frame 61, which is fixedly installed at the bottom of the support frame 1. A guide hopper 62 that communicates with the material bucket 3 is fixedly installed on the inner side of the connecting frame 61. A receiving pipe that communicates with the material bucket 3 is connected to the top of the guide hopper 62. A collection frame 63 that communicates with the bottom of the guide hopper 62 is fixedly installed on the inner side of the connecting frame 61. A collection box 64 that extends to the front side of the collection frame 63 is movably installed inside the collection box 63. A handle is fixedly installed on the front side of the collection box 64, which can be easily pulled out for temporary storage of screened debris.
[0030] The screening assembly 6 has an internally mounted movable mechanism 7 extending to its outer side. The movable mechanism 7 includes a screening plate 71, which is movably installed inside the guide hopper 62 and extends through to the left side of the connecting frame 61. The screening plate 71 has an inclined structure design. The sides of the connecting frame 61 and the guide hopper 62 are provided with through holes adapted to the moving trajectory of the screening plate 71. Two support blocks 72 are fixedly installed on the left and right sides of the inner wall of the guide hopper 62 and located below the screening plate 71. A vibration motor 73 is fixedly installed at the bottom of the screening plate 71. A support rod 74 is movably installed inside the support block 72, extending through to its top and fixedly connected to the screening plate 71. The bottom of the support rod 74 is fixedly connected to a support block 72. The internal support plate 75 has a support spring 76 fixedly installed at its bottom. This modified plastic filler masterbatch granule cooling device effectively improves the granule discharge quality and ease of discharge by setting up the screening component 6 and the movable mechanism 7. The screening plate 71 adopts an inclined structure design. With the cooperation of the vibration motor 73, the screening plate 71 is driven to vibrate through the support rod 74, support plate 75 and support spring 76, which can quickly separate qualified particles from the debris generated by cooling friction. The structural design of the support block 72 and the support spring 76 not only limits the vibration trajectory of the screening plate 71 (adapted by the through holes on the side of the connecting frame 61 and the guide hopper 62), but also effectively helps users to screen out debris from the modified plastic filler masterbatch granules and improve the granule quality.
[0031] The working process of this utility model:
[0032] Step 1: Modified plastic filler masterbatch granules enter the material tank 3 through the feed pipe 4; the drive motor 54 starts, and the bevel gear 55 of its output shaft meshes with the bevel gear 55 on the outside of the rotating cylinder 51, driving the rotating cylinder 51 to rotate, which in turn drives the bent stirring rod 56 to rotate synchronously, stirring and mixing the granules in the material tank 3; at the same time, cooling medium (such as cold water) is introduced into the water pipes 21 on the upper and lower sides of the cooling box 2. The cooling medium circulates in the material tank 3 through the flow holes inside the rotating cylinder 51 and the bent stirring rod 56, making full contact with the granules and carrying away heat, so as to achieve uniform cooling of the granules. The cooling medium in the cooling box 2 cools the modified plastic filler masterbatch granules synchronously through the material tank 3.
[0033] Step 2: After cooling, the particles fall from the bottom of the material bucket 3 onto the screening plate 71 in the guide hopper 62; the vibration motor 73 starts and drives the support rod 74 to vibrate through the support plate 75. The support rod 74 pushes the screening plate 71 to vibrate through the limiting action of the support block 72; the debris accelerates through the screening plate 71 under the action of vibration and falls into the collection box 65 for collection.
[0034] 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.
