Description

Technical Field

[0001] The utility model belongs to the technical field of plastic processing, and in particular relates to a preheating device for the production and processing of plastic particles. Background Art

[0002] Plastic particles are the common name for plastic granules. They are raw materials for storage, transportation and processing of plastics in the form of semi-finished products. Usually, when processing plastic particles, it is often necessary to preheat the raw materials to facilitate subsequent processing.

[0003] A Chinese patent with publication number CN218139202U discloses a preheating device for processing modified plastic particles, including a suction machine 1, a preheating box and a suction machine 2. The suction machine 1, the preheating box and the suction machine 2 are connected by a feed pipe, and a solenoid valve is provided at the connection interface between the feed pipe and the suction machine 1, the preheating box and the suction machine 2. The preheating box is equipped with a preheating mechanism and a stirring mechanism, and the preheating box separates the preheating mechanism and the stirring mechanism by a partition plate.

[0004] The above technical solution transports the material to the preheating box, heats it through the preheating mechanism, and tumbles the material through the stirring structure to make it evenly heated. However, in the actual preheating process, the plastic particles may be of different sizes. When preheating particles of different sizes, small particles are easily softened and condensed if preheated too long. If the preheating time of larger particles is too short, they cannot be preheated thoroughly, affecting subsequent processing. As a result, uneven preheating may occur during the preheating process due to different particle sizes.

[0005] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0028] The utility model will now be further described in detail with reference to the accompanying drawings.

[0029] See also Figure 1-5 As shown, in this embodiment, a preheating device for the production and processing of plastic particles is provided, comprising a suction machine 1 and a preheating box 2, a connecting pipe 3 is installed between the preheating box 2 and the suction machine 1, a stirring plate 4 is rotatably matched on the inner wall of the preheating box 2, and a driving mechanism 5 matched with the stirring plate 4 is installed on one side of the preheating box 2;

[0030] A discharge port 6 is provided on the lower side of the inner wall of the preheating box 2, a receiving port 7 is provided on one side of the inner wall of the discharge port 6, a filter screen 8 is slidably matched on the inner wall of the receiving port 7, a plurality of springs 9 are installed between the filter screen 8 and the receiving port 7, a hidden groove 10 is provided on the upper side of the filter screen 8, a force plate 11 is rotatably matched on the inner wall of the hidden groove 10, a spring 2 12 is installed between the force plate 11 and the hidden groove 10, a discharge valve 13 is fixedly connected to the inner wall of the discharge port 6 on one side of the discharge port 6, and a trigger plate 14 is installed on the upper side of the receiving port 7;

[0031] The inner wall of the preheating box 2 is provided with a heating mechanism 15 .

[0032] The application of one aspect of this embodiment is as follows: when in use, the material is first transported to the preheating box 2 through the connecting pipe 3 by the suction machine 1, and then the driving mechanism 5 and the heating mechanism 15 are started. The material is stirred by the driving mechanism 5 so that the material is heated. During the rotation of the stirring plate 4, the force plate 11 is pressed down, driving the spring 2 12 to move. When the force plate 11 is released, the spring 2 12 drives the force plate 11 to reset, and the filter screen 8 is knocked as a whole to vibrate. After preheating for a certain period of time, the discharge valve 13 is opened to achieve the screening of smaller particles through the filter screen 8, so that the small particles fall off, and the large particles remain on the upper side of the filter screen 8, and the large particles continue to be preheated;

[0033] After the large particles have been preheated for a certain period of time, the driving mechanism 5 can be started to flip, driving the stirring plate 4 to rotate in the opposite direction. When the stirring plate 4 flips and contacts with the force-bearing plate 11, the filter screen 8 can be pushed to hide in the receiving port 7, so that the filter screen 8 is opened, and the larger particles in the opening can fall out of the discharge port 6. When the filter screen 8 is driven to move to a certain position, the force-bearing plate 11 is limited by the discharge valve 13, so that the force-bearing plate 11 is hidden in the hidden groove 10 and separated from the stirring plate 4. Under the action of the spring 9, the filter screen 8 is reset, so that small particles are filtered first and large particles are continued to be processed, so that the preheating is more uniform and thorough for different particle sizes.

[0034] By setting the force-bearing plate 11, it can be achieved that when the stirring plate 4 rotates, the downward pressure of the force-bearing plate 11 will not affect the filter screen 8. After heating for a certain period of time, small particles are filtered through the filter screen 8, and large particles continue to be preheated in the preheating box 2. After preheating for a certain period of time, the flipping drive mechanism 5 drives the filter screen 8 to be hidden in the storage port 7, so that the large particles are discharged from the discharge port 6, thereby achieving different preheating time lengths for large and small particles, making the ion preheating more uniform and thorough.

[0035] The driving mechanism 5 of this embodiment includes a fixed plate 501 fixedly connected to one side of the preheating box 2, and a driving motor 502 fixedly connected to the upper side of the fixed plate 501 and the output end of which is fixedly connected to the stirring plate 4. The driving motor 502 is a forward and reverse motor, which is a prior art and is not an innovative part, so it will not be described in detail. The driving motor 502 can control the direction of rotation of the stirring plate 4, thereby controlling the condition of the filter screen 8.

[0036] The heating mechanism 15 of this embodiment includes two heating chambers 151 opened inside the preheating box 2, a heating tube 152 fixedly connected to the inner walls of the two heating chambers 151, and a closing plate 153 installed on one side of the preheating box 2, and the closing plate 153 is located between the two heating chambers 151. The heating tube 152 is a prior art, which heats the heating chamber 151 by generating heat, and generates heat to heat the inside of the preheating box 2 by heat conduction.

[0037] A handle 16 is fixedly connected to one side of the closing plate 153 of the present embodiment. A screw matching the preheating box 2 is installed on one side of the closing plate 153. The handle 16 increases the convenience of operating the closing plate 153. The screws are used to fix the closing plate 153 and disassemble it, thereby improving the convenience of maintenance.

[0038] A guide groove 17 is provided at the lower side of the hidden groove 10 of this embodiment, and the inner wall of the guide groove 17 is slidably matched with a guide block 18 fixedly connected to the filter screen 8. When the filter screen 8 moves, the guide block 18 slides in the guide groove 17 to improve the stability of the movement of the filter screen 8.

[0039] In this embodiment, a soft protective cloth 19 is installed between the hidden groove 10 and the load-bearing plate 11 . The soft protective cloth 19 facilitates sealing between the load-bearing plate 11 and the hidden groove 10 , thereby reducing the possibility of material entering the hidden groove 10 .
