Detailed implementation mode

[0018] The embodiments of the present utility model will be described in detail below with reference to the attached drawings.

[0019] Embodiment 1: A cooling device for use after plastic products are formed, as Figures 1 - 4 shown, includes a chassis 1, a cooling cylinder 2 is fixedly connected to the chassis 1, a feeding port is opened in the upper part of the cooling cylinder 2, the feeding port of the cooling cylinder 2 is used for feeding plastic products, an overflow port is opened in the lower part of the cooling cylinder 2, a side plate 3 is welded to the cooling cylinder 2, a discharge hopper 4 is fixedly connected to the cooling cylinder 2, the discharge hopper 4 is communicated with the cooling cylinder 2, the position of the overflow port is slightly lower than that of the discharge hopper 4, a discharging mechanism is arranged on the cooling cylinder 2, a circulating mechanism is arranged on the chassis 1, the discharging mechanism is used for discharging the cooled plastic products to facilitate the staff to discharge the materials, and the circulating mechanism is used for intermittently adding cold water into the cooling cylinder 2 to cool down, so as to facilitate continuous operation.

[0020] The discharging mechanism includes a mounting bracket 5, the mounting bracket 5 is fixedly connected to the side plate 3, a motor 6 is fixedly connected to the mounting bracket 5, a rotating shaft 7 is rotatably connected to the side plate 3, the rotating shaft 7 is fixedly connected to the output shaft of the motor 6, the motor 6 is used for driving the rotating shaft 7 to rotate, the rotating shaft 7 is rotatably connected to the cooling cylinder 2, a pushing plate 8 is fixedly connected to the rotating shaft 7, the motor 6 drives the pushing plate 8 to rotate through the rotating shaft 7, and the pushing plate 8 is in close contact with the cooling cylinder 2 and the side plate 3.

[0021] The pushing plate 8 is provided with a hollow structure, and the hollow structure of the pushing plate 8 is used for filtering cooling water.

[0022] Initially, the cooling cylinder 2 is filled with cooling water. The staff puts the formed plastic products into the feeding port at the upper part of the cooling cylinder 2. The formed plastic products will fall into the cooling water in the cooling cylinder 2. The cooling water will absorb the heat of the plastic products to cool the plastic products. After cooling for a period of time, the staff starts the motor 6. The output shaft of the motor 6 rotates to drive the rotating shaft 7 to rotate. The rotating shaft 7 rotates to drive the pushing plate 8 to rotate. The pushing plate 8 rotates into the cooling water and scoops up the cooled plastic products in the direction close to the discharge hopper 4. When the plastic products move to the position of the discharge hopper 4, they will fall out of the discharge hopper 4 under the action of gravity. Through the above operations, it is convenient to discharge the cooled plastic products, facilitating the staff to carry out discharging. The pushing plate 8 is provided with a hollow structure to filter the water and prevent the cooling water from being pushed out of the cooling cylinder 2. After the pushing plate 8 continues to rotate to the initial position, the staff turns off the motor 6, facilitating the next operation.

[0023] Embodiment 2: On the basis of Embodiment 1, as Figures 1 - 3 shown, the circulation mechanism includes a water storage tank 9. The water storage tank 9 is fixedly connected to the chassis 1. The water storage tank 9 is used to let the cooling water cool naturally. The water storage tank 9 is an open-top setting. The water storage tank 9 is located below the overflow port of the cooling cylinder 2. The lower part of the inner wall of the water storage tank 9 is bolted with a water pump 10. A hose 11 is fixedly connected to the water pump 10. The other end of the hose 11 is fixedly connected to the cooling cylinder 2. The water pump 10 is communicated with the cooling cylinder 2 through the hose 11. The water pump 10 pumps the cooling water in the water storage tank 9 into the cooling cylinder 2 through the hose 11. A driving component is provided on the rotating shaft 7.

[0024] The driving component includes a rotating frame 12. The rotating frame 12 is fixedly connected to the rotating shaft 7. The rotating shaft 7 is used to drive the rotating frame 12 to rotate. A contact frame 13 is slidably connected to the side plate 3. A return spring 14 is provided between the contact frame 13 and the side plate 3. The return spring 14 is used to drive the contact frame 13 to reset. A normally closed switch 15 is fixedly connected to the water pump 10. The normally closed switch 15 is communicated with the control circuit of the water pump 10. The contact frame 13 contacts the normally closed switch 15. The rotating frame 12 drives the normally closed switch 15 to open and close through the contact frame 13, thereby controlling the opening and closing of the water pump 10.

[0025] It further includes heat dissipation ribs 16. A plurality of the heat dissipation ribs 16 are fixedly connected to the outer side wall of the water storage tank 9. The plurality of heat dissipation ribs 16 are arranged at uniform intervals. The heat dissipation ribs 16 are used to accelerate the cooling speed of the cooling water.

[0026] Initially, the water storage tank 9 is filled with cooling water, and the water pump 10 is in the off state. After the plastic product is cooled, the rotating shaft 7 rotates to drive the rotating frame 12 to rotate. The rotating frame 12 rotates and contacts the contact frame 13, and pushes the contact frame 13 towards the normally closed switch 15. The return spring 14 is stretched. When the contact frame 13 moves towards the normally closed switch 15, it will press the normally closed switch 15, and the water pump 10 will start and transport the cooling water in the cooling cylinder 2 to the cooling cylinder 2 through the hose 11. Through the above operations, it is convenient to intermittently add cooling water to the cooling cylinder 2 for cooling, which is convenient for continuous operation. The rotating frame 12 continues to rotate and limits the contact frame 13 for a period of time, so that the contact frame 13 continuously presses the normally closed switch 15, allowing the water pump 10 to pump water for a period of time. When the water level in the cooling cylinder 2 rises to the overflow port of the cooling cylinder 2, it will flow out from the overflow port of the cooling cylinder 2 and fall into the water storage tank 9 for natural cooling. The rotating frame 12 continues to rotate and disengages from the contact frame 13. The rotating frame 12 no longer limits the contact frame 13. The return spring 14 will rebound and drive the contact frame 13 to move in the reverse direction. The contact frame 13 moves in the reverse direction and disengages from the normally closed switch 15. The contact frame 13 no longer presses the normally closed switch 15, and the water pump 10 will stop pumping water.

[0027] The heat dissipation ribs 16 can accelerate the heat exchange between the cooling water in the water storage tank 9 and the air, and improve the cooling speed of the cooling water.

[0028] The above are only examples of the present invention and are not used to limit the present invention. All equivalent replacements made within the principle of the present invention shall be included within the protection scope of the present invention. The content not elaborated in detail in the present invention belongs to the well-known prior art of those skilled in the art.
