Description

Technical Field

[0001] This utility model relates to the field of plastic particle mixing technology, and in particular to a plastic particle hot melt mixing device. Background Technology

[0002] Different types of plastics have their own unique properties, such as strength, toughness, heat resistance, and corrosion resistance. By mixing various plastic granules evenly and then hot-melting them, the advantages of each component can be combined to obtain materials with better performance. The most common plastic granule mixing and hot-melting device is the twin-screw extruder. Its core working principle is to use the rotation of two screws in the barrel to mix, convey, melt, and extrude the added plastic granules and other materials, so that the material is extruded from the die head in a specific shape and state, thereby improving the efficiency of plastic granule hot-melt mixing.

[0003] However, during the feeding process, multiple types of plastic granules are continuously dropped out simultaneously. Due to the large variety of plastic granules and the continuous feeding, the materials accumulate in the mixing area. The accumulated materials affect the normal conveying and mixing effect of the double screw, preventing the materials from being fully tumbled and mixed under the action of the screw blades, ultimately leading to a decrease in the uniformity of mixing.

[0004] Therefore, we propose a plastic granule hot melt mixing device to solve the above problems. Utility Model Content

The mixing unit includes multiple mixing tanks, and each mixing tank is provided with a stirring element for preliminary mixing of at least two types of plastic granules entering the mixing tank. The intermittent feeding component is located between the mixing tanks and the mixing container and is used to control the output end of the mixing tank to synchronously and intermittently feed material into the mixing tank.

[0008] Preferably, the intermittent feeding assembly includes a first motor and a control plate connected to the output shaft of the first motor. The control plate has a plurality of discharge holes corresponding to the mixing tank. When the output end of the mixing tank is aligned with or misaligned with the discharge hole, it is used to control the opening and closing of the output end of the mixing tank.

[0009] Preferably, the mixing tank is provided with a support frame, and the support frame is provided with a support plate for fixing multiple mixing tanks, and the first motor is provided on the support plate.

[0012] Preferably, the bottom of the control plate is provided with a limiting cover to prevent plastic particles from splashing out.

[0013] The beneficial effects of this utility model are as follows: by randomly placing various plastic particles into the mixing tank, and using a stirring component to initially stir and mix the plastic particles inside each mixing tank, and by using an intermittent feeding component to release the initial mixture from each mixing tank into the mixing tank in small amounts multiple times, the accumulation of plastic particles caused by continuous feeding is avoided, and the small amount of plastic particles also improves the mixing efficiency.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0022] Reference Figures 1-5 As shown, a plastic granule hot melt mixing device includes a mixing unit, which comprises multiple mixing tanks 3. Each mixing tank 3 is equipped with a stirring element 4 for initially mixing at least two types of plastic granules entering the mixing tank 3. Different plastic granules have unique properties, and the plastic granules to be mixed for hot melt mixing differ in strength, toughness, heat resistance, and corrosion resistance. For example, four types of plastic granules are prepared: plastic granule No. 1, plastic granule No. 2, plastic granule No. 3, and plastic granule No. 4. Four mixing tanks 3 are also prepared. Combinations of plastic granule No. 1 and No. 2, plastic granule No. 2 and No. 3, plastic granule No. 3 and No. 4, and plastic granule No. 4 and No. 1 are respectively placed in the four mixing tanks 3. Then, the stirring element 4 in each mixing tank 3 initially mixes the plastic granules. In the initial mixing stage, the types of plastic particles are relatively few, reducing the impact of differences in properties. After initial mixing in multiple mixing tanks 3, the plastic particles enter the subsequent process in a more uniform binary combination. Then, the intermittent feeding component 5 located below the mixing tank 3 controls the output end of the mixing tank 3 to feed intermittently. The plastic particles falling from the mixing tank 3 enter the interior of the mixing tank 2. When these binary combinations are mixed again, the overall mixing process is easier to control. Intermittent feeding allows the plastic particles to enter in batches and in small quantities. The plastic particles in the mixing tank 2 are always in a relatively loose and easy-to-mix state. Then, they enter the double spiral conveyor mechanism from the mixing tank 2 for secondary mixing and hot melting. Under the action of the double spiral mixing conveyor mechanism 1, the plastic particles interweave and are more thoroughly stirred. This not only avoids the accumulation of plastic particles caused by continuous feeding, but also improves the mixing efficiency by mixing a small amount of plastic particles each time.

[0023] Reference Figure 4 , Figure 5As shown, furthermore, in order to reduce the accumulation of plastic particles caused by continuous feeding, the intermittent feeding component 5 includes a first motor 51 and a control plate 52 connected to the output shaft of the first motor 51. The control plate 52 has multiple discharge holes 6 corresponding one-to-one with the mixing tank 3. In use, the time interval of each intermittent feeding can be controlled by adjusting the speed of the first motor 51. The control plate 52 is attached to the output end of each mixing tank 3. In use, the first motor 51 drives the control plate 52 to rotate. When rotating, the output end of the mixing tank 3 is aligned with the discharge hole 6, and the plastic particles in the mixing tank 3 fall out. As the control plate 52 rotates, the output end of the mixing tank 3 and the discharge hole 6 gradually become misaligned. The control plate 52 seals the mixing tank 3. During this process, the plastic particles stop falling and are separated from the plastic particles that have entered the double spiral mixing and conveying mechanism 1 for a certain period of time to avoid accumulation.

[0024] In order to prevent the falling plastic particles from splashing when the control plate 52 rotates, a limiting cover 11 is provided at the bottom of the control plate 52 to prevent the plastic particles from splashing out. If the limiting cover 11 does not restrain the plastic particles during the falling process, the control plate 52 will easily carry the particles away from the original feeding path when it rotates, causing the particles to splash everywhere. The limiting cover 11 can effectively block the plastic particles from splashing out, so that the plastic particles can only fall within a limited area, avoiding the scattering of a large number of plastic particles and keeping the production environment clean.

[0025] Reference Figures 1-3 As shown, further, in order to improve stability, a support frame 7 is provided on the mixing tank 2, and a support plate 8 is provided on the support frame 7 for fixing multiple mixing tanks 3. During the operation of the equipment, the stirring component 4 in the mixing tank 3 will generate vibration when stirring the plastic particles. The support of the mixing tank 3 can prevent the mixing tank 3 from shifting or shaking due to stirring vibration, and maintain a stable feeding and mixing process. At the same time, in order to maintain the stability of the first motor 51, the first motor 51 is mounted on the support plate 8.

[0026] Reference Figure 3 As shown, further, in order to mix the plastic particles in the mixing tank 3, the stirring component 4 includes a second motor 41 and stirring rods 42 that are staggered along the length extension direction of the output shaft of the second motor 41. When the plastic particles are inside the mixing tank 3, the stirring rods 42 are rotated by turning on the second motor 41, so that the plastic particles in the mixing tank 3 are stirred and mixed. In order to prevent the plastic particles from falling out or impurities from entering during stirring, a bucket lid 9 is detachably connected by means of snap-fit, magnetic attraction, etc. The second motor 41 is located on the bucket lid 9, which improves the stability and convenience of use.

[0027] Reference Figure 3As shown, furthermore, in order to disperse the plastic particles falling into the mixing tank 2, a multi-layered inclined dispersion net 10 is provided inside the mixing tank 2. The dispersion net 10 can intercept the falling plastic particle flow, and the plastic particles slide down along the inclined net surface, causing the plastic particles to collide and slide with the net surface. With different degrees of change in direction and speed, this gives different types of plastic particles more opportunities to interweave and mix with each other. Compared with the case without the dispersion net 10, it greatly increases the probability of mixing between plastic particles, further improves the mixing effect, and helps to produce products with more stable and uniform performance.
