[0011] A blocking block is arranged at the top end of the connecting rod, and the blocking block is matched with the constricted part of the inner diameter of the feed pipe;

[0012] A spring is arranged between the blocking block and the support frame, and in normal state, the spring force of the spring makes the blocking block abut against the constricted part of the inner diameter of the feed pipe to prevent heat loss in the machine body; when pouring from the top of the feed pipe, the paint falls on the blocking block, and the blocking block is lowered under the pressure of the paint, and the paint enters the machine body from the gap between the blocking block and the inner wall of the feed pipe, thereby reducing the heat loss in the machine body.

[0013] Further, a cover is installed on the feed pipe to block the opening at the top of the feed pipe.

[0014] Further, the feeding pipe is hinged with the cover.

[0015] Further, a connecting block one is arranged on the cover, a connecting block two is arranged on the feeding pipe, and the connecting block one and the connecting block two are hinged through a connecting shaft.

[0019] (Three) beneficial effects

[0020] Compared with the prior art, the powder coating drying mechanism with the crushing function has the following beneficial effects:

[0021] The powder coating drying mechanism with the crushing function, through the inner diameter contraction of the middle part of the feeding pipe and the arrangement of the blocking block and the spring, under normal conditions, the spring force makes the blocking block abut against the inner diameter contraction part of the feeding pipe, a good sealing structure is formed, and the heat in the machine body can be effectively prevented from being dissipated outward through the feeding pipe. During the coating injection process, the coating falls on the blocking block, the blocking block is lowered under pressure, and the coating enters the machine body from the gap between the blocking block and the inner wall of the feeding pipe. The gap is much smaller than the opening area of the existing open feeding pipe, and the coating will pass through the gap during the coating injection process, thereby playing a role in sealing the gap, greatly reducing the heat dissipation channel, and minimizing the heat loss during the coating injection process.

[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0029] Please refer to Figures 1-5 The utility model discloses a powder coating drying mechanism with crushing function, including the machine body 1 that has the crushing function and the drying function in one, be provided with feeding pipe 2 on the machine body 1, the inner diameter of feeding pipe 2 middle part is set to contract, the bottom of machine body is provided with the discharge port, and the powder coating of crushing and drying is discharged.

[0030] The bottom of feeding pipe 2 is installed with support frame 3, and the top of connecting rod 4 is provided with blocking piece 5, and the blocking piece 5 is matched with the inner diameter contraction part of feeding pipe 2, and the top of blocking piece 5 is provided with curved surface, which can also be provided with inclined plane, which is beneficial to the blanking and prevents the material from remaining on the blocking piece 5. The spring 6 is arranged between the blocking piece 5 and the support frame 3, and the spring force of spring 6 makes the blocking piece 5 abut against the inner diameter contraction part of feeding pipe 2 to prevent the heat loss in the machine body 1, when the material is injected from the top of feeding pipe 2, the coating falls on the blocking piece 5, and the blocking piece 5 is lowered under the pressure of the coating, and the coating enters the machine body 1 from the gap between the blocking piece 5 and the inner wall of feeding pipe 2, and the heat loss in the machine body 1 is reduced during the feeding process. The end of connecting rod 4 is provided with limiting block 12 to prevent the connecting rod 4 from being separated from the support frame 3.

[0031] The cover 7 for plugging the opening of the top of feeding pipe 2 is installed on the feeding pipe 2, and the feeding pipe 2 is hinged with the cover 7 to facilitate the opening and closing of the cover. The specific connection relationship is that the connecting block one 8 is arranged on the cover 7, the connecting block two 9 is arranged on the feeding pipe 2, and the connecting block one 8 and the connecting block two 9 are hinged through the connecting shaft 10. The handle 11 is arranged on the cover 7.

[0032] The long driving rod (not shown in the figure) is arranged on the blocking piece 5, but the length thereof is not higher than that of the cover 7, when the material is injected through the top of feeding pipe 2 and falls on the blocking piece 5, if it is desired to accelerate the falling speed of the material, the staff need not wait for the slow downward pressure of the blocking piece 5 by the gravity of the material itself, but can directly manually press down the driving rod. The blocking piece 5 can be driven to fall, and then the material can enter the machine body 1 from the gap between the blocking piece 5 and the inner wall of feeding pipe 2 more quickly, and the feeding efficiency is significantly improved.

[0033] In actual use, sometimes there is too little material. When the weight of the residual material is not enough to make the blocking block 5 descend, causing the material to remain on the blocking block 5, the staff can actively make the blocking block 5 overcome the elastic force of the spring 6 to descend by pressing the driving rod, so that the residual material falls into the machine body 1 smoothly. Effectively avoid material residues, ensure that the feeding process is more thorough, and reduce material waste.

[0034] In summary, the powder coating drying mechanism with crushing function, when using, the equipment in no feeding, the blocking block 5 at the bottom of the feeding pipe 2 is affected by the elastic force of the spring 6, tightly fits the contraction part of the inner diameter of the feeding pipe 2, prevents the heat loss inside the machine body 1.

[0035] The material is poured from the top of the feeding pipe 2, and the material naturally falls on the blocking block 5. As the material increases, its gravity will overcome the elastic force of the spring 6, so that the blocking block 5 gradually descends, and the material enters the machine body 1 from the gap between the blocking block 5 and the inner wall of the feeding pipe 2.

[0036] If you need to speed up the material descending speed, the operator can directly manually press the driving rod on the blocking block 5. The driving rod will make the blocking block 5 quickly descend, increase the gap between the material and the inner wall of the feeding pipe 2, and thus speed up the speed of the material entering the machine body 1.

[0037] When the material is too little, the residual material cannot make the blocking block 5 descend by its own weight, the operator needs to press the driving rod again. By manually applying external force, the blocking block 5 overcomes the elastic force of the spring 6 to descend, ensuring that the material remaining on the blocking block 5 falls into the machine body 1.

[0038] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
