Description

Technical Field

[0001] This utility model relates to the field of plastic granule mixing technology, and in particular to an anti-sticking cylinder for a PC plastic granule mixer. Background Technology

[0002] Polycarbonate (PC) is a general term for high molecular weight compounds that contain carbonate linkages in their main molecular chain. During the production of plastic granules, a mixer is needed to mix the plastic granules. The mixing cylinder is one of the core components of the mixer, which can hold materials for mixing.

[0003] For example, CN219076175U discloses a horizontal plastic granule mixer, including a base, a horizontal mixing cylinder, a stirring shaft, a stirring rod, and a drive assembly for driving the stirring shaft to rotate. A main pipe is opened through the center of the stirring shaft, and a branch pipe connected to the main pipe is opened through the center of the stirring rod. A one-way flow assembly is fixed at the end of the stirring rod away from the stirring shaft. A water supply assembly and an air supply assembly are fixed on the base. Valves are provided at both ends of the stirring shaft. The water supply assembly is connected to one end of the stirring shaft through a preset rotary water connector.

[0004] In the prior art, the inner wall of the mixing drum of the mixer is easily adhered to by water-containing plastic particles. When the material adheres to the inner wall of the drum, the amount of material participating in normal mixing will be relatively reduced, and the flow and mixing effect of the material will be affected, resulting in uneven mixing. Furthermore, the adhered material will gradually accumulate and may block the discharge port or the feed port, hindering the normal conveying of the material. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the inner wall of the mixing drum of the existing mixer is easily adhered by water-containing plastic particles, and the material gradually accumulates, which may block the discharge port or the feed port and hinder the normal conveying of the material. Therefore, an anti-sticking drum for a PC plastic particle mixing machine is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an anti-sticking cylinder for a PC plastic granule mixer, comprising a support frame, a mixing cylinder mounted on the top of the support frame, a second anti-sticking mechanism installed inside the mixing cylinder, and a first anti-sticking mechanism provided outside the mixing cylinder. The first anti-sticking mechanism includes a sliding frame, one end of which is fixedly connected to the top of the support frame, a push plate slidably connected inside the sliding frame, a compression spring installed between the push plate and the sliding frame, a first moving plate fixedly connected to one end of the push plate, a connecting block fixedly connected to one side of the first moving plate, and an anti-sticking vibrating plate fixedly connected to one end of the connecting block. The inner side of the anti-sticking vibrating plate overlaps with the outer side of the mixing cylinder.

[0007] Preferably, a drive motor is fixedly connected to the top of the support frame, a connecting shaft is fixedly connected to the output end of the drive motor, and a rotating push plate is fixedly connected to the outside of the connecting shaft.

[0008] Preferably, a fixing block is fixedly connected to the other side of the first movable plate, and a second guide rod is slidably connected inside the fixing block. One end of the second guide rod is fixedly connected to one side of the support frame.

[0009] Preferably, a first guide rod is fixedly connected inside the sliding frame, and the outside of the first guide rod is slidably connected to the push plate, with the compression spring sleeved on the outside of the first guide rod.

[0010] Preferably, the second anti-sticking mechanism includes a rotating rod, one end of which is fixedly connected to the inside of the mixing cylinder, one end of the connecting shaft passes through one end of the mixing cylinder and is fixedly connected to the other end of the rotating rod, and a connecting rod is fixedly connected to the outside of the rotating rod. The multiple connecting rods are divided into two groups, and an anti-sticking scraper is fixedly connected to the ends of both groups of connecting rods.

[0011] Preferably, a helical blade is fixedly connected to the outside of the connecting rod.

[0012] Preferably, the mixing cylinder has a feed inlet at the top and a discharge outlet at the bottom.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the drive motor drives the connecting shaft to rotate, and the rotating push plate rotates accordingly. The rotating push plate pushes the two push plates outward, compresses the spring, and the movement of the push plate drives the first moving plate to move. The connecting block and the anti-sticking vibration plate move accordingly. Then the rotating push plate rotates until it separates from the push plate. The compressed spring works to push the push plate to move, which drives the anti-sticking vibration plate to strike the outside of the mixing cylinder. This makes it easier for the plastic particles adhering to the inner wall of the mixing cylinder to fall off under force, preventing the plastic particles from adhering to the inner wall of the mixing cylinder and affecting the flow and mixing effect of the material.

[0015] 2. In this utility model, during the operation of the drive motor that drives the connecting shaft to rotate, the rotating rod rotates accordingly, and the connecting rod and the spiral blade move to mix the material inside the mixing cylinder. At the same time, the anti-stick scraper moves with the connecting rod and can scrape off the material inside the mixing cylinder to prevent the material from adhering to the inner wall of the mixing cylinder and affecting the mixing effect.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 - Figure 4As shown, this utility model provides an anti-sticking cylinder for a PC plastic granule mixer, including a support frame 1. A mixing cylinder 4 is mounted on the top of the support frame 1. A second anti-sticking mechanism 6 is installed inside the mixing cylinder 4, and a first anti-sticking mechanism 2 is provided on the outside of the mixing cylinder 4. The first anti-sticking mechanism 2 includes a sliding frame 27. One end of the sliding frame 27 is fixedly connected to the top of the support frame 1. A push plate 24 is slidably connected inside the sliding frame 27. A compression spring 26 is installed between the push plate 24 and the sliding frame 27. A first moving plate 21 is fixedly connected to one end of the push plate 24. A connecting block 28 is fixedly connected to one side of the first moving plate 21. One end of the connecting block 28 is fixedly connected to... There is an anti-sticking vibration plate 211, the inner side of which overlaps with the outer side of the mixing cylinder 4; a drive motor 5 is fixedly connected to the top of the support frame 1, a connecting shaft 22 is fixedly connected to the output end of the drive motor 5, and a rotating push plate 23 is fixedly connected to the outside of the connecting shaft 22; a fixing block 29 is fixedly connected to the other side of the first moving plate 21, a second guide rod 210 is slidably connected inside the fixing block 29, and one end of the second guide rod 210 is fixedly connected to one side of the support frame 1; a first guide rod 25 is fixedly connected inside the sliding frame 27, and the outside of the first guide rod 25 is slidably connected to the push plate 24, and a compression spring 26 is sleeved on the outside of the first guide rod 25.

[0024] The drive motor 5 is a geared motor. The drive motor 5 drives the connecting shaft 22 to rotate, causing the rotating push plate 23 to rotate accordingly. During the rotation of the rotating push plate 23, both ends of the rotating push plate 23 push the two push plates 24 outwards. The push plates 24 slide outside the first guide rod 25, and the compression spring 26 compresses, causing the fixed push plate 24 to move linearly. The movement of the push plate 24 drives the first moving plate 21 to move, and the connecting block 28 and the anti-vibration plate 211 move accordingly. The fixed block 29 slides outside the second guide rod 210, facilitating the movement of the first moving plate 21. The moving plate 21 moves stably, and then the rotating push plate 23 rotates until it separates from the pushing plate 24. The compressed spring 26 works to push the pushing plate 24 to move, which in turn drives the first moving plate 21 and the anti-sticking vibration plate 211 to move. The anti-sticking vibration plate 211 can strike the outside of the mixing cylinder 4. By rotating the push plate 23 continuously, the anti-sticking vibration plate 211 is driven to reciprocate to strike the outer wall of the mixing cylinder 4, which makes it easier for the plastic particles adhering to the inner wall of the mixing cylinder 4 to fall off under force, and prevents the plastic particles from adhering to the inner wall of the mixing cylinder 4 and affecting the flow and mixing effect of the material.

[0025] Example 2: Figure 1 and Figure 3As shown, the second anti-sticking mechanism 6 includes a rotating rod 61, one end of which is fixedly connected to the inside of the mixing cylinder 4. One end of the connecting shaft 22 passes through one end of the mixing cylinder 4 and is fixedly connected to the other end of the rotating rod 61. A connecting rod 63 is fixedly connected to the outside of the rotating rod 61. The multiple connecting rods 63 are divided into two groups, and an anti-sticking scraper 62 is fixedly connected to the ends of both groups of connecting rods 63. A spiral blade 64 is fixedly connected to the outside of the connecting rod 63. A feed inlet 3 is installed at the top of the mixing cylinder 4, and a discharge outlet 7 is installed at the bottom of the mixing cylinder 4.

[0026] The overall effect of this embodiment is that, during the operation of the drive motor 5 which drives the connecting shaft 22 to rotate, the rotating rod 61 rotates accordingly, and the connecting rod 63 and the spiral blades 64 move. Through the arrangement of multiple spiral blades 64, the material inside the mixing cylinder 4 can be mixed. At the same time, an anti-sticking scraper 62 is installed at the end of the connecting rod 63. As the anti-sticking scraper 62 moves with the connecting rod 63, it can scrape off the material inside the mixing cylinder 4, preventing the material from adhering to the inner wall of the mixing cylinder 4 and affecting the mixing effect. The material is fed in through the feed port 3 set at the top of the mixing cylinder 4 and discharged through the discharge port 7 set at the bottom of the mixing cylinder 4.

[0027] The operating method and working principle of this device are as follows: The drive motor 5 drives the connecting shaft 22 to rotate, and the rotating push plate 23 rotates accordingly, pushing the two push plates 24 outward. The compression spring 26 is compressed, and the movement of the push plate 24 drives the first moving plate 21 to move. The connecting block 28 and the anti-sticking vibration plate 211 move accordingly. Then, the rotating push plate 23 rotates until it separates from the push plate 24. The compressed spring 26 works to push the push plate 24 to move, driving the first moving plate 21 and the anti-sticking vibration plate 211 to move. The anti-sticking vibration plate 211 can strike the outside of the mixing cylinder 4, and the plastic particles adhering to the inner wall of the mixing cylinder 4 fall off under the force. During the process of the drive motor 5 driving the connecting shaft 22 to rotate, the rotating rod 61 rotates accordingly, and the connecting rod 63 and the spiral blade 64 move to mix the material inside the mixing cylinder 4. At the same time, during the process of the anti-sticking scraper 62 moving with the connecting rod 63, the material inside the mixing cylinder 4 can be scraped off.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
