DETAILED DESCRIPTION

[0023] The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings. The described embodiments are only some of the embodiments, not all of them. Based on the embodiments in this solution, all other embodiments obtained by ordinary technicians in this field without making creative work are within the protection scope of this solution.

[0024] Example 1

[0025] like Figure 1 to Figure 2 As shown, this embodiment designs a screen printing device for convex surface printing, including a screen printing mold 4, a clamp roller seat 3, a transmission gear 14, a rack 10 and a screen printing plate brush 5 and other components.

[0026] The clamp roller seat 3 can adopt a U-shaped structure, and a detachable clamp roller body 12 is arranged on the clamp roller seat 3. Specifically, a rotatable connecting seat is arranged at one end of the clamp roller seat 3, and the connecting seat can be connected to the clamp roller seat 3 through a ball bearing. The connecting seat is coaxially connected to one end of the clamp roller body 12 in a threaded connection, a clamping connection or a plug-in connection. The other end of the clamp roller body 12 is supported by the other end of the clamp roller seat 3, and the clamp roller seat 3 rolls the clamp roller seat 3. Two supporting wheels can be arranged on the upper end of the other end of the clamp roller seat 3, and the other end of the clamp roller body 12 is supported by the two supporting wheels and rolls on the supporting wheels. When the connecting seat rotates, the clamp roller body 12 can be driven to rotate synchronously.

[0027] The roller surface of the clamp roller body 12 is provided with an installation slot 13 for product installation and fixing; when a product is printed on the surface, another product of the same category can be manually replaced for printing. When a different category of product needs to be replaced, the clamp roller body 12 can be replaced.

[0028] The screen printing mold 4 is arranged above the clamp roller body 12. When printing, the lower surface of the screen printing mold 4 is in close contact with the convex surface of the product, so that the paint can be adsorbed on the surface of the product. The screen printing plate brush 5 is arranged above the screen printing mold 4 and is used to brush the paint on the screen printing mold 4; when the screen printing plate brush 5 brushes over the upper surface of the screen printing mold 4, it can promote the flow of paint and print it on the surface of the product at the corresponding position.

[0029] The transmission gear 14 is connected to the clamp roller body 12 and meshes with the rack 10; the rack 10 can move relative to the clamp roller body 12 along with the screen printing mold 4 and control the rotation of the clamp roller body 12. The transmission gear 14 can be coaxially connected to the connecting seat.

[0030] A lifting platform 9 is arranged on the upper side of the silk-screen printing mold 4, and the silk-screen printing mold 4 can be lifted and lowered along with the lifting platform 9. The lifting platform 9 can be threadedly matched with a vertical screw rod, and the lifting and lowering movement of the lifting platform 9 can be controlled by the rotation of the screw rod. A side vertical plate can be arranged on the rear side of the lifting platform 9, and a track can be arranged on the front side of the side vertical plate to guide the lifting platform 9 vertically.

[0031] The lifting platform 9 is provided with a transverse translation platform 8, and the lower part of the transverse translation platform 8 is connected with a mold bracket 11, and the mold bracket 11 can move in the left and right directions relative to the lifting platform 9 together with the transverse translation platform 8; the screen printing mold 4 is detachably connected to the mold bracket 11. A transverse guide rod can be provided on the front side of the lifting platform 9, and the transverse wire rod passes through the transverse translation platform 8 and the two slide and cooperate with each other, so that the transverse translation platform 8 can move along the transverse guide rod. The lifting platform 9 can be connected to an electric cylinder, a pneumatic cylinder or a hydraulic cylinder to control the movement of the transverse translation platform 8 in the left and right directions.

[0032] The longitudinal translation platform 7 is slidably connected to the front side of the transverse translation platform 8, and the longitudinal translation platform 7 can move in the front-to-back direction relative to the transverse translation platform 8. A longitudinal guide rod is arranged on the front side of the transverse translation platform 8, and the longitudinal wire rod passes through the longitudinal translation platform 7 and the two slide and cooperate with each other, so that the longitudinal translation platform 7 can move in the front-to-back direction along the longitudinal guide rod. An electric cylinder, a pneumatic cylinder or a hydraulic cylinder can be arranged on the transverse translation platform 8 to control the movement of the longitudinal translation platform 7 in the front-to-back direction.

[0033] A plate brush clamp 6 is arranged below the longitudinal translation platform 7, and the plate brush clamp 6 can move in the up and down directions relative to the transverse translation platform 8. An electric cylinder, an air cylinder or a hydraulic cylinder can be arranged on the longitudinal translation platform 7, and the plate brush clamp 6 is installed on the piston rod of the electric cylinder, the air cylinder or the hydraulic cylinder, so as to control the movement of the plate brush clamp 6 in the up and down directions; the plate brush clamp 6 is used to fix the screen printing plate brush 5 and drive the vertical lifting and lowering movement of the screen printing plate brush 5.

[0034] One end of the rack 10 is rotatably connected to the mold bracket 11, and the other end is freely hanging down, so that the tooth pattern on the lower surface of the rack 10 is always in mesh with the transmission gear 14.

[0035] When the silk screen printing device in this embodiment is in use, the product to be printed is mounted and fixed on the clamp roller body 12, and then the position of the mold bracket 11 is moved downward so that the lower surface of the silk screen printing mold 4 is in close contact with the surface of the product, and then the position of the silk screen printing plate brush 5 is moved so that the silk screen printing plate brush 5 is in close contact with the upper surface of the silk screen printing mold 4; the relative position of the silk screen printing plate brush 5 and the clamp roller seat 3 is kept unchanged, and then the silk screen printing mold 4 is moved in the left and right directions, and in this process, the rack 10 drives the transmission gear 14 and the clamp roller body 12 to rotate, so that the convex surface of the surface of the product rolls relative to the lower surface of the silk screen printing mold 4, so that the paint can be printed on the product.

[0036] The above embodiments are merely examples for the purpose of clarifying the description, and are not intended to limit the implementation methods; it is not necessary and impossible to list all implementation methods exhaustively. However, obvious changes or modifications derived therefrom are still within the scope of protection of the present technology.
