Technical Field

[0001] This utility model relates to the field of plastic product manufacturing technology, specifically to a plastic surface printing device. Background Technology

[0002] As is well known, plastics are defined as follows: mainly composed of carbon, oxygen, hydrogen, nitrogen, and other organic or inorganic elements. The finished product is a solid, but during the manufacturing process, it is a molten liquid. Therefore, it can be heated to melt it, pressurized to make it flow, and cooled to solidify it, thus forming various shapes. This vast and diverse group of materials is called plastics. In the production process of plastic products, in order to meet the needs of different consumers, it is necessary to print on the surface of plastic products to obtain different shapes of prints and improve their aesthetics.

[0003] Currently, printing rollers are generally used to print on plastic products. However, dust remains on the surface of plastic products after the initial processing, so the surface of the plastic products needs to be cleaned before printing.

[0004] Therefore, we propose a plastic surface printing device. Utility Model Content

[0005] The purpose of this invention is to provide a plastic surface printing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plastic surface printing device, comprising a base plate, a printing mechanism disposed on the top of the base plate, a support frame fixedly mounted on the top of the base plate in front of the printing mechanism, a rotating bracket fixedly mounted on the top of the base plate in front of the support frame, movable boxes fixedly mounted on both sides of the support frame, sliding grooves formed on both sides of the support frame, movable gears rotatably connected to the middle of both sides of the support frame and located inside the movable boxes, racks slidably connected to the front and rear sides inside the movable boxes, and gears fixedly mounted on the upper and lower sides inside the movable boxes in close contact with the racks. A retaining spring is used. The rack meshes with a movable gear. One end of the rack is rotatably connected to a dust-adhesive roller located inside the support frame. A cleaning roller brush is rotatably connected inside the rotating bracket. A drive motor is fixedly installed on the top of the rotating bracket. A blower located on one side of the drive motor is fixedly installed on the top of the rotating bracket. The output end of the drive motor is connected to one end of the cleaning roller brush. An air supply pipe is fixedly installed at the air outlet of the blower. A diffuser pipe is fixedly installed at the other end of the air supply pipe. A nozzle is fixedly installed on the outer circumferential surface of the diffuser pipe. Both ends of the diffuser pipe are fixedly installed to the opposite surfaces of the support frame and the rotating bracket, respectively.

[0007] Optionally, a rotating ring is integrally provided at one end of the rack, and the rotating ring of the rack is slidably connected to the inside of the sliding groove. The two ends of the sticky roller are respectively rotatably connected to the middle of the rotating ring.

[0008] Optionally, the four air ducts are divided into two groups and fixedly installed on the top and bottom of the support frame and the rotating bracket, respectively. The nozzles of the air ducts are arranged opposite to the nozzles of the other air duct arranged diagonally.

[0009] Optionally, a first synchronous pulley is fixedly installed at the output end of the drive motor, and a second synchronous pulley located outside the rotating bracket is fixedly installed at one end of one of the cleaning roller brushes. The second synchronous pulley is connected to the first synchronous pulley via a synchronous belt.

[0010] Optionally, a transmission gear is fixedly installed on the same side of the two cleaning roller brushes on the other side of the rotating bracket, the two transmission gears mesh, and the two cleaning roller brushes are arranged vertically inside the rotating bracket.

[0011] Optionally, the racks are symmetrically arranged inside the movable box with the center of the movable gear as the center of symmetry, and the two racks are integrally connected to rotating rings that are rotatably connected to the two ends of the two sticky rollers respectively.

[0012] Optionally, the movable gear is located in the middle of the two sliding grooves, and the center of the movable gear coincides with the midpoint of the line connecting the two sliding grooves.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This plastic surface printing device uses a drive motor to rotate the first and second synchronous wheels, causing the upper cleaning roller to rotate. Two transmission gears cause the lower cleaning roller to rotate at the same speed but in opposite directions. When the plastic product is conveyed between the two cleaning rollers, the two cleaning rollers simultaneously clean both the top and bottom surfaces of the plastic product. After cleaning, the plastic product passes through two sets of air ducts, where airflow from the nozzles completely blows away any residual dust on the surface of the plastic product, ensuring the quality of the printing.

[0015] This plastic surface printing device uses adhesive rollers. When a plastic product enters between two adhesive rollers, the adhesive rollers drive a rack to move up and down. The two racks, which mesh with the movable gear, move at the same distance, ensuring that the two adhesive rollers move the same distance. This results in the lower and upper adhesive rollers applying the same pressure to the upper and lower sides of the plastic product, preventing deformation and damage to the plastic product due to different pressures from the lower and upper adhesive rollers.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4This utility model provides a plastic surface printing device, including a base plate 1, a printing mechanism 2 disposed on the top of the base plate 1, a support frame 3 fixedly installed on the top of the base plate 1 in front of the printing mechanism 2, a rotating bracket 10 fixedly installed on the top of the base plate 1 in front of the support frame 3, movable boxes 4 fixedly installed on both sides of the support frame 3, sliding grooves 8 opened on both sides of the support frame 3, movable gears 5 rotatably connected to the middle of both sides of the support frame 3 and located inside the movable boxes 4, racks 6 slidably connected to the front and rear sides inside the movable boxes 4, and clamping springs 9 fixedly installed on the upper and lower sides inside the movable boxes 4 and in close contact with the racks 6, the racks 6 meshing with the movable gears 5, and a dust-adhesive roller 7 rotatably connected to one end of the racks 6 and located inside the support frame 3, the rotating bracket 10 rotating inside the support frame 3 and the rotating bracket 10 rotating inside the support frame 3. A cleaning roller brush 11 is dynamically connected. A drive motor 12 is fixedly installed on the top of the rotating bracket 10. A blower 13 located on one side of the drive motor 12 is fixedly installed on the top of the rotating bracket 10. The output end of the drive motor 12 is connected to one end of the cleaning roller brush 11. An air supply pipe 14 is fixedly installed at the air outlet of the blower 13. A diffuser pipe 15 is fixedly installed at the other end of the air supply pipe 14. A nozzle 16 is fixedly installed on the outer circumferential surface of the diffuser pipe 15. The two ends of the diffuser pipe 15 are fixedly installed to the opposite surfaces of the support frame 3 and the rotating bracket 10, respectively. The four diffuser pipes 15 are divided into two groups and fixedly installed to the top and bottom of the support frame 3 and the rotating bracket 10, respectively. The nozzle 16 of the diffuser pipe 15 is set opposite to the nozzle 16 of the other diffuser pipe 15 set diagonally.

[0023] A rotating ring is integrally provided at one end of the rack 6. The rotating ring of the rack 6 is slidably connected to the inside of the sliding groove 8. The two ends of the sticky roller 7 are rotatably connected to the middle of the rotating ring. The rack 6 is symmetrically arranged inside the movable box 4 with the center of the movable gear 5 as the center of symmetry. The rotating rings integrally connected to the two racks 6 are rotatably connected to the two ends of the two sticky rollers 7. The movable gear 5 is located in the middle of the two sliding grooves 8. The center of the movable gear 5 coincides with the midpoint of the line connecting the two sliding grooves 8. By setting the sticky rollers 7, when the plastic product enters between the two sticky rollers 7, the sticky rollers 7 drive the rack 6 to move up and down. The two racks 6 meshing with the movable gear 5 have the same distance when moving, so that the two sticky rollers 7 move the same distance. This makes the pressure of the lower sticky roller 7 and the upper sticky roller 7 on the upper and lower sides of the plastic product the same, preventing the plastic product from being deformed or damaged due to the different pressure of the lower sticky roller 7 and the upper sticky roller 7.

[0024] A first synchronous pulley 18 is fixedly installed at the output end of the drive motor 12. A second synchronous pulley 20 located outside the rotating bracket 10 is fixedly installed at one end of a cleaning roller brush 11. The second synchronous pulley 20 is connected to the first synchronous pulley 18 via a synchronous belt 19. A transmission gear 17 located on the other side of the rotating bracket 10 is fixedly installed on the same side of the two cleaning roller brushes 11. The two transmission gears 17 mesh. The two cleaning roller brushes 11 are arranged vertically inside the rotating bracket 10. The drive motor 12 drives the first synchronous pulley 18 and the second synchronous pulley 20 to rotate, causing the upper cleaning roller brush 11 to rotate. The two transmission gears 17 cause the lower cleaning roller brush 11 to rotate at the same speed but in opposite directions. When the plastic product is conveyed between the two cleaning roller brushes 11 through the conveying equipment, the two cleaning roller brushes 11 clean the upper and lower surfaces of the plastic product at the same time. The cleaned plastic product passes through the airflow sprayed from the nozzle 16 between the two sets of air ducts 15, which completely blows away the residual dust on the surface of the plastic product, ensuring the quality of the printing.

[0025] Working principle:

[0026] The drive motor 12 drives the first synchronous wheel 18 and the second synchronous wheel 20 to rotate, causing the upper cleaning roller brush 11 to rotate. Through two transmission gears 17, the lower cleaning roller brush 11 rotates at the same speed but in opposite directions. When the plastic product is conveyed between the two cleaning roller brushes 11 through the conveying equipment, the two cleaning roller brushes 11 clean the upper and lower surfaces of the plastic product simultaneously. The cleaned plastic product passes through the two sets of air ducts 15, and the airflow sprayed from the nozzles 16 completely blows away the residual dust on the surface of the plastic product, ensuring the quality of the printing. When the plastic product enters between the two dust-adhesive rollers 7, the dust-adhesive rollers 7 drive the rack 6 to move up and down. The two racks 6 that mesh with the movable gear 5 move at the same distance, so that the two dust-adhesive rollers 7 move the same distance. This ensures that the lower dust-adhesive roller 7 and the upper dust-adhesive roller 7 exert the same pressure on the upper and lower sides of the plastic product, preventing the plastic product from being deformed or damaged due to different pressures exerted by the lower dust-adhesive roller 7 and the upper dust-adhesive roller 7.
