DETAILED DESCRIPTION

[0023] The following will be combined with the attached embodiment of the utility model Figure 1-5 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] like Figures 1 to 5As shown, the utility model discloses a plastic particle cooling device, including a cooling box 1, a feeding vehicle 2 and a motion mechanism for enabling the feeding vehicle 2 to intermittently feed are arranged above the cooling box 1, and at the same time, a cooling chamber 11 and a water storage chamber 12 are arranged inside the cooling box 1, wherein the cooling chamber 11 is located above the water storage chamber 12, in this structure, the cooling chamber 11 is connected with the water storage chamber 12 and a water flow opening and closing mechanism is arranged between the cooling chamber 11 and the water storage chamber 12, the water flow opening and closing mechanism is used to close or open the connection between the cooling chamber 11 and the water storage chamber 12, in addition, a water supply pipe 31 is arranged on the cooling box 1, the water supply pipe 31 is connected with the water storage chamber 12 and is used to inject water into the cooling chamber 11, and a water pump 32 and a refrigeration mechanism are arranged on the water supply pipe 31.

[0026] The working principle of the above structure is as follows: first, the water supply pipe 31 transports the water cooled by the refrigeration mechanism into the cooling chamber 11. When the feeding vehicle 2 is to feed plastic particles, the water flow opening and closing mechanism isolates the cooling chamber 11 and the water storage chamber 12 from each other. The water supply pipe 31 continues to inject water into the cooling chamber 11 until the water storage chamber 12 is full. After the plastic particles are cooled, the plastic particles are salvaged. The water flow opening and closing mechanism connects the cooling chamber 11 and the water storage chamber 12 to each other. The water circulates between the cooling chamber 11, the water storage chamber 12 and the water supply pipe 31 while being cooled by the refrigeration mechanism. When the water temperature drops again, the water flow opening and closing mechanism isolates the cooling chamber 11 and the water storage chamber 12 from each other again, and the feeding vehicle 2 feeds again, and the cycle repeats.

[0027] The specific structure of the feeding trolley 2 is as follows: the feeding trolley 2 includes a support frame, the support frame includes a fixed axis 21, the fixed axis 21 is transversely arranged above the cooling box 1, and a rotating drum 22 is concentrically sleeved on the outer side of the fixed axis 21. A plurality of hoppers 23 are fixedly arranged on the outer side wall of the rotating drum 22 along the circumferential direction. At the same time, in this structure, a motion mechanism is used to make the rotating drum 22 perform unidirectional intermittent rotation, specifically: a plurality of claw grooves 24 are opened on the inner side wall of the rotating drum 22 along the circumferential direction, and the motion mechanism includes an elastic telescopic rod, which is fixedly arranged on the fixed axis 21 and extends toward the claw groove 24, and a slope 25 is arranged on one side of the end of the elastic telescopic rod away from the fixed axis 21, and the slope 25 is inclined toward the claw groove 24. The side wall on one side of the groove 24 is used to contact the lower end of the side wall of the claw groove 24. In addition, the side of the elastic telescopic rod facing away from the slope 25 is used to abut against the side wall of the claw groove 24. In this structure, the feeding direction of the feeding cart 2 should be opposite to the direction of the slope 25 of the elastic telescopic rod, that is, with the fixed axis 21 as the center of the circle, an arc is drawn between the side where the slope 25 of the elastic telescopic rod is set and the side where the slope 25 of the elastic telescopic rod is not set. If the feeding cart 2 rotates clockwise to feed, then the end of the arc away from the slope 25 can only be moved counterclockwise to make the end of the arc away from the slope 25 close to the end of the arc close to the slope 25 on the arc's path.

[0028] The elastic telescopic rod includes a first rod portion 26 and a second rod portion 27 . The first rod portion 26 is fixedly disposed on the fixed shaft 21 , and the second rod portion 27 is slidably disposed on the first rod portion 26 . A spring 28 is disposed between the first rod portion 26 and the second rod portion 27 .

[0029] The working principle of this structure is as follows: the device feeds the hopper 23 on the feeding cart 2 through an external feeding pipe 6. When the plastic particles in the hopper 23 reach a certain weight, the claw groove 24 inside the feeding cart 2 can push the elastic telescopic rod to contract, thereby causing the feeding cart 2 to rotate. When the plastic particles in the hopper 23 fall into the cooling chamber 11, the force used to drive the feeding cart 2 to rotate becomes smaller, and the corresponding pushing force of the claw groove 24 on the elastic telescopic rod also becomes smaller, and the elastic telescopic rod can be extended again and stuck in the claw groove 24, thereby preventing the feeding cart 2 from continuing to rotate.

[0030] An isolation plate for separating the cooling chamber 11 and the water storage chamber 12 is provided in the cooling box 1, and the isolation plate includes a first partition 13 and a second partition 14 located on the right side of the first partition 13. The first partition 13 is in the shape of a slope 25 and is inclined downward toward the second partition 14. The second partition 14 is arranged horizontally, and a water hole 15 for connecting the cooling chamber 11 and the water storage chamber 12 is provided at one end of the second partition 14 close to the first partition 13. The working principle of this structure is: when the plastic particles are not salvaged cleanly, the water flow can follow the first partition 13 to gather the plastic particles at the second partition 14, thereby facilitating the collection of the plastic particles.

[0031] The water flow opening and closing mechanism includes a water baffle 44, a motor 41, a gear 42 and a rack 43. The water baffle 44 is slidably arranged below the second partition 14, the motor 41 is fixedly installed on the outer wall of the cooling box 1, the rack 43 is fixedly arranged at the lower end of the water baffle 44, the gear 42 is rotatably arranged in the cooling box 1 and meshes with the rack 43, and the output end of the motor 41 penetrates into the working box and is connected with the gear 42.

[0032] The refrigeration mechanism includes a cooling circulation pipe 33, a part of the cooling circulation pipe 33 is arranged on the outside of the water supply pipe 31, and the other part of the cooling circulation pipe 33 is inserted into the inside of the water supply pipe 31. The cooling circulation pipe 33 is equipped with a refrigeration box 34. The working principle of the refrigeration box 34 and the cooling circulation pipe 33 is the same as the prior art, mainly that the refrigerant in the cooling circulation pipe 33 flows in one direction. When it flows to the refrigeration box 34, the refrigeration box 34 cools down the refrigerant in the cooling circulation pipe 33, so that the cooling circulation pipe 33 can exchange heat with the water in the water supply pipe 31.

[0033] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
