Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary jigs, in particular to an auxiliary jig for a UV printer. Background Art

[0002] A UV printer is a high-tech full-color digital printing machine without plate-making, which is not restricted by materials. It can perform color photo-level printing on the surfaces of T-shirts, sliding doors, cabinet doors, sliding doors, glass, plates, various signs, crystals, PVC, acrylic, metals, plastics, stones, leathers, etc. During the UV printing process, an auxiliary jig is often required to clamp the printing substrate to facilitate the UV printing on its surface. The Chinese authorized utility model patent (Publication No.: CN219988812U) discloses an auxiliary jig for a UV printer, which can monitor the clamping force of the printing substrate during the UV printing process to avoid scratches on the surface of the printing substrate due to excessive clamping force or slippage of the printing substrate due to insufficient clamping force.

[0003] However, there are still some deficiencies in the above device during use: specifically, during the clamping process, the operator usually needs to manually hold up the object to keep it stable in the horizontal position. After both ends of the object come into contact with the clamping plates and are clamped, the staff then release their hands. This not only increases the complexity and labor intensity of the operation, but also easily causes the object to tilt after being clamped due to human factors, resulting in printing deviation and affecting the final printing effect. Therefore, an auxiliary jig for a UV printer is proposed for the above situation. Summary of the Utility Model

[0004] The auxiliary jig for a UV printer proposed by the utility model has the advantages of ensuring that the object is always in a horizontally placed state and improving the UV printing quality.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An auxiliary jig for a UV printer includes a U-shaped frame, a driving mechanism is arranged on the U-shaped frame, and a threaded block is arranged on the driving mechanism.

[0007] A first clamping member is arranged on the top of the threaded block, and a second clamping member is arranged at one end of the U-shaped frame far from the threaded block.

[0008] The first clamping member includes a vertical plate, the vertical plate is fixed on the top of the threaded block, through holes and a first through groove are respectively formed on the vertical plate, a motor is fixedly connected to the vertical plate, the output shaft of the motor passes through the through hole, and the protruding end of the output shaft of the motor is fixedly connected to a first clamping plate.

[0009] A first support plate is fitted in the first through groove, a first electric push rod is arranged on the threaded block, and the moving end of the first electric push rod is fixedly connected to the first support plate.

[0010] The second clamping member includes a vertical plate fixed on a U-shaped frame. A second clamping plate is provided on the vertical plate, and a second through groove is formed on the vertical plate. A support plate is fixedly connected to the U-shaped frame. A second electric push rod is provided at the top of the support plate, and a second support plate is fixedly connected to the moving end of the second electric push rod. The second support plate cooperates with the second through groove. A rectangular groove is formed on the outer surface of the U-shaped frame, and the rectangular groove communicates with the second through groove.

[0011] Preferably, a through hole is formed on the vertical plate, a rotating shaft is rotatably fitted in the through hole, a pressure sensor is installed at one end of the rotating shaft away from the vertical plate, and a second clamping plate is provided on the pressure sensor.

[0012] Preferably, a PLC control host is fixedly connected to one side of the outer surface of the U-shaped frame close to the second clamping plate.

[0013] Preferably, fixing plates are provided on both sides of the outer surface of the U-shaped frame. The fixing plates are L-shaped and have reserved holes.

[0014] Preferably, threaded holes and round holes are respectively formed through the threaded block, and the threaded holes and the round holes respectively cooperate with the driving mechanism.

[0015] Preferably, there is a gap between the bottom of the first clamping plate and the top of the first support plate, and there is a gap between the bottom of the second clamping plate and the top of the second support plate.

[0016] The utility model has the following beneficial effects:

[0017] 1. Through the structural design of the first through groove, the first support plate, the second through groove and the second support plate, when in use, the bottoms of both ends of the article to be printed can be supported and lifted, reducing the labor intensity of the operator. At the same time, during the movement of the first clamping plate, the article is always in a horizontally placed state, avoiding printing errors caused by the inclination of manual lifting, thus significantly improving the quality of UV printing.

[0018] 2. Through the structural design of the first support plate, the first electric push rod, the second electric push rod and the second support plate, after positioning the article to be printed, the first support plate and the second support plate can be retracted, avoiding the occlusion of the surface of the object during reverse printing, improving the flexibility of printing, and further improving the printing quality.

[0030] In this embodiment, during use, first connect an external power supply and a switch to the electrical equipment in this device. When it is necessary to fix the item to be printed, simultaneously turn on the switches of the first electric push rod 405 and the second electric push rod 504 to make them work. The first electric push rod 405 works to push the first support plate 404 to move out from the first through groove 4010, and the second electric push rod 504 works to push the second support plate 505 out from the second through groove 5010. At this time, turn off the switches of the first electric push rod 405 and the second electric push rod 504, and then the two ends of the item to be printed can be placed on the first support plate 404 and the second support plate 505. Then, make the threaded block 3 move through the work of the driving mechanism, that is, make the first clamping plate 403 move towards the second clamping plate 502 to complete the clamping of the item. After clamping, turn on the switches of the first electric push rod 405 and the second electric push rod 504 again. The moving ends of the first electric push rod 405 and the second electric push rod 504 make a contraction movement, respectively making the first electric push rod 405 and the second support plate 505 retract, and then no longer lift the positioned item.

[0038] In this embodiment, due to the existence of the gap, the first supporting plate 404 and the second supporting plate 505 can work without interfering with the first clamping plate 403 and the second clamping plate 502.

[0039] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
