[0030] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0031] Example 1:

[0032] Please refer to Figure 1-4 A reciprocating sprayer for plastic products includes a sprayer body 1, a reciprocating mechanism 2, and a nozzle 3. The reciprocating mechanism 2 is provided at the upper end of the sprayer body 1, and the nozzle 3 is provided inside the reciprocating mechanism 2, which facilitates comprehensive spraying of plastic products. In order to reduce the negative impact on the environment during the spraying process, a retaining frame 4 is further provided inside the reciprocating mechanism 2 and outside the nozzle 3. The retaining frame 4 is detachably connected to the reciprocating mechanism 2.

[0033] A hydraulic cylinder 13 is fixed at the center of the spraying machine body 1. A material placement seat 14 is fixed to the telescopic end of the hydraulic cylinder 13. The outer side of the material placement seat 14 is in contact with the inner side of the spraying machine body 1. When the plastic product is placed on the upper end of the material placement seat 14, in order to facilitate auxiliary positioning of the plastic product and prevent the plastic product from moving during the spraying and drying process, electric telescopic rods 15 are symmetrically fixed to the inner side of the material placement seat 14. The telescopic ends of the two electric telescopic rods 15 are both fixed with a material pressing frame 16. The two material pressing frames 16 are both slidably connected to the material placement seat 14, making it convenient to clamp the plastic product.

[0034] When the hydraulic cylinder 13 drives the material placement seat 14 and the plastic product on its upper end to shrink and move down to the inside of the spraying machine body 1, in order to facilitate the rapid drying of the plastic product, a carrying seat 17 is symmetrically fixed on the inside of the spraying machine body 1 and on the outside of the material placement seat 14. Two exhaust fans 18 are fixed on the inside of each carrying seat 17. In order to significantly reduce the entry of dust and impurities into the inside of the spraying machine body 1, dustproof nets 19 are fixed on the inside of both ends of the spraying machine body 1. In order to heat the air temperature and further improve the drying efficiency, electric heating rods 20 are provided on the inside of the spraying machine body 1 and between each carrying seat 17 and the dustproof net 19.

[0035] Example 2:

[0036] The reciprocating spraying machine for plastic products provided in Example 1 is further optimized, specifically, as Figure 3-4 As shown, after the material placement seat 14 and the plastic product are driven into the inside of the spraying machine body 1 by the hydraulic cylinder 13, in order to facilitate the blocking of the upper end of the spraying machine body 1, supports 5 are fixed at both ends of the upper end of the spraying machine body 1, and a blocking component is provided between the two supports 5;

[0037] Specifically, the blocking assembly includes a guide column 6 and a bidirectional screw 7. A guide column 6 and a bidirectional screw 7 are respectively provided between the two supports 5 and on the outside of the material placement seat 14. The guide column 6 is fixed to the two supports 5, and the bidirectional screw 7 is rotatably connected to the two supports 5. The outer side of the bidirectional screw 7 is symmetrically threaded with a blocking plate 11. The two blocking plates 11 are both slidably connected to the guide column 6. In order to limit the moving stroke of the blocking plate 11, a limiting ring 12 is symmetrically fixed to the outer side of the guide column 6. A first bevel gear 8 is fixed to the outer side of one end of the bidirectional screw 7. A reduction motor 9 is fixed inside the spraying body 1 and at the lower end of the first bevel gear 8. A second bevel gear 10 is fixed to the output end of the reduction motor 9, and the second bevel gear 10 is meshed with the first bevel gear 8.

[0038] After the air flow is guided to the inside of the sprayer body 1 by the exhaust fan 18 and the upper end of the sprayer body 1 is blocked by the blocking assembly, exhaust holes 21 are provided inside the sprayer body 1 and on both sides of the material placement seat 14 to facilitate exhaust. In order to prevent air from entering the inside of the sprayer body 1 through the exhaust holes 21, one-way air valves 22 are provided on the outside of the sprayer body 1 and on the outsides of the two exhaust holes 21.

[0039] The above electrical components are all electrically connected to a main controller and a power supply, wherein the main controller can be a conventional known device such as a computer for control, and the existing disclosed power connection technology will not be repeated here;

[0040] The use process of the reciprocating sprayer for plastic products provided by the present invention is as follows: after placing the plastic product to be processed on the upper end of the material placement seat 14, the two electric telescopic rods 15 are started to drive the two pressing racks 16 to move closer to each other to assist in clamping and limiting the plastic product, and then the blocking frame 4 is installed to the outside of the spray head 3 to reduce the negative impact on the environment during the spraying process, and then the spraying operation is started;

[0041] After the plastic product is fully and evenly sprayed, the hydraulic cylinder 13 is started to drive the material placement seat 14 and the plastic product on its upper end to move down to the inside of the spraying machine body 1, and the reduction motor 9 is started to drive the second bevel gear 10 to rotate. The engagement of the second bevel gear 10 with the first bevel gear 8 drives the bidirectional screw 7 to rotate, and then drives the two blocking plates 11 to approach each other through the guidance of the guide column 6 to block the upper end of the spraying machine body 1. At this time, the exhaust fan 18 is started to cooperate with the dustproof net 19 to guide the air outside the spraying machine body 1 to the inside of the spraying machine body 1, and the air flow is heated when passing through the electric heating rod 20, so that the drying efficiency can be further improved when the air flow contacts the plastic product, and it is not easy to be contaminated by dust and impurities. Finally, the air flow is discharged outward through the exhaust hole 21 and the one-way air valve 22.
