[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0029] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-3 A cooling device for powder coating production includes a screw conveyor 1 mounted on a base.

[0030] The screw conveyor 1 has an automatic folding assembly 2 installed on its conveyor chain plate 11, and a cloth belt 3 carrying powder coating is installed on the conveyor chain plate 11 and the automatic folding assembly 2. The screw conveyor 1 is equipped with an auxiliary cooling mechanism 5 for cooling the powder coating in the cloth belt 3. The auxiliary cooling mechanism 5 includes a material turning assembly 51 and a cooling assembly 52. ​​Multiple sets of material turning assemblies 51 for turning materials are installed on the side of the screw conveyor 1, and the cooling assembly 52 is installed on the screw conveyor 1.

[0031] A swing feeding structure 7 is installed on the base; a conformal suction nozzle 6 is fixedly installed on the upper side of the screw conveyor 1; the lower end of the conformal suction nozzle 6 is aligned with the fabric belt 3, and the upper end of the conformal suction nozzle 6 is connected to the pneumatic conveying equipment through a pipe.

[0032] The screw conveyor 1 is a commercially available and mature device, such as the multi-layer chain plate screw conveyor produced by Shanghai Manxin Machinery Co., Ltd.

[0033] Pneumatic conveying equipment is a mature technology in this field.

[0034] In this embodiment, when the cooling device for powder coating production is working normally, the spiral elevator 1 drives the conveyor chain plate 11 to move cyclically, thereby driving the automatic folding component 2 and the fabric belt 3 to move cyclically. Through the automatic folding component 2, the two ends of the fabric belt 3 are folded up as it spirals upward with the conveyor chain plate 11, thereby preventing the powder coating from falling off the fabric belt 3. The powder coating is fed onto the lower fabric belt 3 by the oscillating feeding structure 7, making the powder coating fall onto the fabric belt 3 more evenly, thereby improving the heat dissipation efficiency. During the upward process, the powder coating on the fabric belt 3 is turned over by the turning component 51, further improving the heat dissipation efficiency. During this process, the heat is exchanged between the cooling component 52 and the powder coating, and the heat is carried away by the cooling component 52. Until the powder coating is conveyed to the upper side by the conveyor chain plate 11, the cooled coating is collected by the conformal suction nozzle 6, thereby completing the cooling of the powder coating. This application occupies a small area, extends the moving distance of the powder coating in a limited space, and the feeding, cooling and unloading processes are carried out continuously, which can effectively improve the cooling efficiency during production.

[0035] Example 2: In some embodiments, such as Figures 1-5 As shown, in a preferred embodiment of this utility model, the automatic folding assembly 2 includes a rotating rod 22, and the conveyor chain plate 11 includes a connecting chain and evenly arranged chain plates; the chain plates of the conveyor chain plate 11 have mounting grooves 21 on both sides, and the mounting grooves 21 are hinged to the lower end of the rotating rod 22; a torsion spring is sleeved on the hinge shaft of the rotating rod 22 and the mounting groove 21, and the two elastic legs of the torsion spring abut against the mounting groove 21 and the rotating rod 22 respectively; the length of the rotating rod 22 is greater than the length of the mounting groove 21; the middle part of the fabric belt 3 is fixedly connected to the chain plate of the conveyor chain plate 11, and the two ends of the fabric belt 3 are fixedly connected to the outer ends of the two rotating rods 22 respectively;

[0036] The automatic folding assembly 2 also includes a support platform 23. The support platform 23 is symmetrically fixedly installed on both sides of the spiral conveyor chain plate 11 that rises along the spiral on the spiral elevator 1. The bottom of the support platform 23 is provided with an inclined guide surface. The upper end of the rotating rod 22 slides in contact with the support platform 23.

[0037] In its natural state, the rotating rod 22 is located in the mounting groove 21 on the side of the conveyor chain plate 11. Before the conveyor chain plate 11 moves to the spiral rise, the outer end of the rotating rod 22 is supported by the support platform 23, so the support platform 23 pushes the rotating rod 22 to rotate upward, thereby causing the side of the cloth belt 3 to fold upward, preventing the powder coating in the cloth belt 3 from overflowing.

[0039] The material turning module includes a mounting frame 511, a lever 512, a turning plate 513, and a connecting rod 514. The mounting frame 511 is fixedly installed on the side of the screw conveyor 1. The middle part of the lever 512 is rotatably connected to the mounting frame 511, and the lower side of the lever 512 is fixedly connected to one end of the turning plate 513. Multiple levers 512 are provided, and the multiple levers 512 are evenly distributed at equal intervals on the mounting frame 511. The upper ends of the multiple levers 512 are rotatably installed on the connecting rod 514 at equal intervals.

[0040] The drive module includes a first electric push rod 515, a moving block 516, and a slider 518. The first electric push rod 515 is fixedly mounted on the mounting bracket 511. The moving block 516 is fixedly mounted on the output end of the first electric push rod 515. A sliding groove 517 is opened on the inner side of the moving block 516. The slider 518 is fixedly mounted on the outer end of the connecting rod 514. The slider 518 slides in contact with the sliding groove 517.

[0041] During the upward conveying of powder, the first electric push rod 515 drives the moving block 516 to move. The moving block 516 drives the slider 518 to move through the slide groove 517. The slider 518 moves and pushes the connecting rod 514 to move. The connecting rod 514 pushes the lever 512 to move, thereby causing the lever 512 to swing. The swing center of the lever 512 is the hinge point between the mounting frame 511 and the lever 512, thereby driving the tilting plate 513 to swing. The tilting plate 513 flips the powder coating.

[0042] The cooling assembly 52 includes a support frame 521 and cooling pipes 522. The support frame 521 is fixedly installed on the screw conveyor 1, and multiple cooling pipes 522 are fixedly installed on the support frame 521.

[0044] During the movement, cooling water is continuously pumped into the cooling pipe 522 by an external water pump. The cooling water flowing in the cooling pipe 522 carries away heat and accelerates cooling.

[0045] The swing feeding structure 7 includes a second support frame 71, a swing bucket 72, and a second electric push rod 73. The second support frame 71 is fixedly installed on the base platform, and the upper side of the second support frame 71 is rotatably connected to the side of the swing bucket 72. The second electric push rod 73 is rotatably installed on the side of the second support frame 71, and the output end of the second electric push rod 73 is rotatably connected to the swing bucket 72.

[0046] The second electric push rod 73 drives the swing bucket 72 to swing, causing the lower end of the swing bucket 72 to swing back and forth, thus feeding the powder coating onto the cloth belt 3 through the swing bucket 72, making the powder coating more uniform on the cloth belt 3.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
