Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and in particular to a mixing machine for plastic processing. Background Technology

[0002] Plastic processing, also known as plastic molding, mainly involves molding plastics into plastic products. This process requires the coordinated work of multiple steps. First, the raw materials need to be mixed and stirred to ensure that different types of plastic particles are mixed more evenly during melting and molding, thereby improving the wear resistance and strength of the plastic. Therefore, a plastic processing mixer is needed to fully mix the plastic particles to facilitate subsequent processing and molding.

[0003] However, the existing technology has the following shortcomings: since there are many types of plastic particles that need to be mixed together, and the mixing of plastic particles is usually done by horizontal stirring, the particles are constantly pushed by the stirring paddle and moved in the same area (such as the prior art with publication number CN119635864A), which makes it difficult for different types of plastic particles to be fully mixed, and the mixing efficiency is low, the structure is complex, and it is not conducive to subsequent maintenance work; therefore, this application proposes a mixing machine for plastic processing. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a mixing machine for plastic processing.

[0005] An embodiment of this utility model provides a mixing machine for plastic processing, comprising:

[0006] A support frame on which a mixing cylinder is mounted;

[0007] A mixing assembly includes a shaft that passes through and is rotatably connected to a mixing cylinder. Multiple connecting rods are mounted on the shaft, and a stirring plate is fixed on the connecting rod. An inverted, channel-shaped guide plate is fixed on the stirring plate. The stirring plate rotates with the shaft and can scrape up the plastic. The plastic moving with the stirring plate can roll to both sides on the channel-shaped guide plate.

[0008] Furthermore, the upper end of the mixing cylinder is connected to an arc-shaped cover plate that mates with the mixing cylinder, and a handle is fixed on the arc-shaped cover plate.

[0009] Furthermore, the bottom of the mixing cylinder is provided with a discharge port, and the bottom of the mixing cylinder is hinged to an arc-shaped bottom cover that seals the discharge port and is configured to cooperate with the mixing cylinder.

[0010] Furthermore, a driving component is mounted on the bracket, a driving shaft is fixed to the output end of the driving component, and a transmission wheel is mounted on the shaft and the driving shaft. The two transmission wheels are connected by a transmission belt.

[0011] Furthermore, the inner sides of the arc-shaped cover plate and the arc-shaped bottom cover are both arc-shaped. When the arc-shaped cover plate and the arc-shaped bottom cover are closed on the mixing cylinder, the arc-shaped cover plate, the arc-shaped bottom cover, and the mixing cylinder form a complete cylinder.

[0012] Furthermore, both the mixing plate and the channel-shaped guide plate are made of stainless steel, and the mixing plate and the channel-shaped guide plate are welded together.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention utilizes a channel-shaped guide plate to roll plastic particles onto both sides. When the mixing plate scrapes the plastic particles again, the plastic particles accumulated on both sides roll towards the center. The plastic particles that have not detached from the channel-shaped guide plate eventually detach from the channel-shaped guide plate due to gravity. This achieves efficient mixing of plastic particles in the mixing drum, and the structure is simple and easy to maintain. Attached Figure Description

Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1-Figure 4 As shown in the figure, this utility model embodiment proposes a mixing machine for plastic processing, comprising:

[0022] The support frame 1 is made of high-strength alloy steel, possessing sufficient load-bearing capacity and stability to ensure that it will not shake or deform during the operation of the mixing machine. A mixing cylinder 6 is securely mounted on the support frame 1 using bolts. The mixing cylinder 6 is made of high-quality stainless steel, possessing excellent corrosion resistance and wear resistance, capable of adapting to the mixing needs of different types of plastic granules, and is easy to clean and maintain.

[0023] The upper end of the mixing cylinder 6 is connected to an arc-shaped cover plate 7 via a hinge shaft. A handle 8 is fixed to the arc-shaped cover plate 7 for easy operation. The surface of the handle 8 is treated with an anti-slip coating to increase friction when the operator grips it and prevent slippage. The bottom of the mixing cylinder 6 is equipped with a discharge port 13. The size of the discharge port 13 is rationally designed according to the flow rate requirements of plastic granules in actual production to ensure smooth discharge and prevent blockage.

[0024] The bottom of the mixing cylinder 6 is hinged to an arc-shaped bottom cover 14 that seals the discharge port 13 and mates with the mixing cylinder 6. A sealing strip is provided on the contact surface between the arc-shaped bottom cover 14 and the mixing cylinder 6 to enhance the sealing effect and prevent leakage of plastic particles during mixing. The inner sides of both the arc-shaped cover 7 and the arc-shaped bottom cover 14 are arc-shaped. This design allows the arc-shaped cover 7, arc-shaped bottom cover 14, and mixing cylinder 6 to form a complete cylinder when they are closed on the mixing cylinder. This not only does not obstruct the rotation of the stirring plate 11 but also facilitates smooth circulation of plastic particles within the mixing cylinder, improving the mixing effect.

[0025] The mixing assembly includes a shaft 9 that passes through the mixing cylinder 6 and is rotatably connected to it via bearings. The bearings are high-performance sealed bearings, effectively preventing plastic particles from entering the bearing and extending its service life. A drive unit 2 is mounted on the support 1, and a drive shaft 3 is fixed to the output end of the drive unit 2. The drive unit 2 includes a motor and a gearbox mounted on the support 1. The motor is a variable frequency motor, allowing for flexible control by adjusting the frequency to change the stirring speed according to the mixing requirements of different plastic particles. The motor and gearbox are connected by a coupling with good alignment and shock absorption performance, ensuring stable transmission between the motor and gearbox. The drive shaft 3 is fixed to the shaft end of the gearbox.

[0026] A transmission wheel 4 is mounted on shaft 9 and drive shaft 3, and the two transmission wheels 4 are connected by a transmission belt 5. The transmission wheels 4 are synchronous pulleys, and the transmission belt 5 is also a synchronous belt, which can ensure the accuracy and stability of transmission and avoid slippage.

[0027] Multiple connecting rods 10 are bolted to the shaft 9. The number and spacing of the connecting rods 10 are reasonably set according to the size of the mixing drum 6 and the stirring requirements to ensure uniform stirring effect. A stirring plate 11 is fixed to the connecting rod 10 by welding. The weld is ground to make the surface smooth and prevent residual plastic particles. The stirring plate 11 can be rectangular or as shown in the figure.

[0028] An inverted, channel-shaped guide plate 12 is fixed to the mixing plate 11 by bolts. The depth and width of the channel-shaped guide plate 12 are optimized according to the size and flowability of the plastic particles, so that the mixing plate 11 can scrape up the plastic when it rotates with the shaft 9. The plastic moving with the mixing plate 11 can roll to both sides on the channel-shaped guide plate 12, thereby increasing the collision and mixing opportunities between plastic particles and improving the mixing efficiency.

[0029] Plastic particles that roll to both sides via the channel-shaped guide plate 12 accumulate on both sides. When the mixing plate 11 scrapes the plastic particles again, the plastic particles accumulated on both sides roll towards the center. In addition, plastic particles that do not detach from the channel-shaped guide plate 12 eventually detach from the channel-shaped guide plate 12 due to gravity. This achieves efficient mixing of plastic particles in the mixing drum 6, and the structure is simple and easy to maintain.

[0030] Both the mixing plate 11 and the channel-shaped guide plate 12 are made of stainless steel. The mixing plate 11 and the channel-shaped guide plate 12 are welded together. The welding quality has been strictly tested to ensure that the connection is firm and reliable and can withstand a large mixing force.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
