Technical Field

[0001] The invention relates to the technical field of processing equipment for plastic production, in particular to plastic granulation cooling equipment. Background Art

[0002] Plastic granulation is the process of making plastic particles of a certain shape and size through melting, extrusion, cooling, and pelletizing of plastic raw materials. These particles can be used directly as raw materials for subsequent plastic product processing, such as injection molding, extrusion, blow molding, etc. The particles after plastic granulation can be used as raw materials and widely used in the processing of various plastic products, such as household appliances, auto parts, office supplies, daily necessities, wires and cables, pipes, building materials and other fields.

[0003] Traditional plastic granulation equipment mostly uses water cooling to cool the finished product. However, direct contact between high-temperature plastic particles and water is prone to quality problems. In addition, the direct contact water cooling method also requires separate drying, which increases the production process. Summary of the invention

[0004] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a plastic granulation cooling device, which solves the problem that traditional plastic granulation equipment mostly uses water cooling to cool the finished product, and the direct contact between high-temperature plastic particles and water is likely to cause quality problems, and the direct contact water cooling method also requires separate drying afterwards, which increases the production process.

[0005] (II) Technical solution To achieve the above objectives, the present invention is implemented through the following technical solutions: a plastic granulation cooling device, comprising a processing box, a servo motor and a cooling box, the driving end of the servo motor passes through the top of the processing box and extends to the interior thereof and is fixedly connected to a transmission shaft through a telescopic rod, the end of the transmission shaft away from the servo motor is fixedly connected to the cooling box, the end of the cooling box away from the transmission shaft is fixedly connected to a transmission rod, the end of the transmission rod away from the cooling box is rotatably connected to the inner bottom of the processing box, an outer surface of the transmission shaft is surrounded by an adjustment slot, the adjustment slot extends in a vertical direction, the inner side wall of the processing box is fixedly connected to a fixed shaft, and the end of the fixed shaft away from the processing box is slidably engaged in the inside of the adjustment slot.

[0006] Preferably, the transmission rod is a telescopic rod, and a plurality of driving card plates are fixedly connected to the outer surface of the transmission rod at the telescopic position, and the plurality of driving card plates are arranged in a ring array. Preferably, the outer surface of the transmission rod is sleeved with a transmission cylinder, and the inner wall of the transmission cylinder is provided with an adjustment slot corresponding to the driving card plate, and the outer wall of the transmission cylinder is fixedly connected to a plurality of negative pressure plates, and the plurality of negative pressure plates are distributed in a ring array, and the curvature of the upper surfaces of the plurality of negative pressure plates is greater than the curvature of their lower surfaces.

[0007] Preferably, a limiting cylinder is provided inside the processing box, the limiting cylinder is fixedly connected to the inner side wall of the processing box, and one end of the driving clamping plate away from the transmission cylinder is slidably connected to the inner side wall of the limiting cylinder.

[0008] Working principle: When in use, place the plastic particles that need to be cooled inside the cooling box, add two-thirds of the volume of coolant into the processing box, start the servo motor, and the driving end of the servo motor rotates the transmission shaft through the telescopic rod. Since the adjustment slot opened around the outer surface of the transmission shaft extends in the vertical direction, and the fixed shaft fixedly connected to the inner wall of the processing box is slidably connected to the inside of the adjustment slot, when the transmission shaft rotates, it will move back and forth in the vertical direction. Since the end of the transmission shaft away from the servo motor driving end is fixedly connected to the top of the cooling box, it will While the cooling box makes periodic motion in the vertical direction, it also makes rotational motion, which increases the degree of contact between the cooling box and the coolant. The periodic dynamic motion, combined with the inertia of the material movement inside the cooling box, can cool the material well. During the movement of the cooling box, the transmission rod is fixedly connected to the bottom of the cooling box, and a plurality of driving pallets are fixedly connected to the outer surface of the transmission rod. The driving pallets can drive the transmission cylinder to rotate with the negative pressure plate. The negative pressure generated by the rotation of the negative pressure plate can drive the coolant to continuously flush the cooling box, further improving the heat conduction effect and accelerating the processing efficiency.

[0009] (III) Beneficial effects The present invention provides a plastic granulation cooling device. It has the following beneficial effects: 1. When the transmission shaft of the plastic granulation cooling equipment rotates, it will make a reciprocating motion in the vertical direction. Since the end of the transmission shaft away from the servo motor drive end is fixedly connected to the top of the cooling box, it will make a periodic motion of the cooling box in the vertical direction and also make a rotational motion, which provides the contact degree between the cooling box and the coolant. The periodic dynamic motion, combined with the inertia of the material movement inside the cooling box, can cool the material well.

[0010] 2. In the process of movement of the cooling box of the plastic granulation cooling equipment, since the transmission rod is fixedly connected to the bottom of the cooling box, and multiple driving clamps are fixedly connected to the outer surface of the transmission rod, the driving clamps will drive the transmission cylinder to rotate with the negative pressure plate. The negative pressure generated by the rotation of the negative pressure plate can drive the coolant to continuously flush the cooling box, further improving the heat conduction effect and accelerating the processing efficiency.
