Description

Technical Field

[0001] This utility model relates to the technical field of printing post-processing equipment, specifically a dust removal device for a water-based ink sanding machine. Background Technology

[0002] In the modern printing industry, to achieve high-end and unique visual effects, printed materials are often treated with a frosted finish. The process is as follows: First, water-based ink is evenly sprayed onto the substrate, such as an acrylic sheet. Then, a drying device is used to completely evaporate the water and volatiles in the ink, forming a solid, hardened ink film. Finally, a frosting machine is used to locally grind this solid ink film to obtain the final target pattern. Dust is generated during the grinding process.

[0003] The sanding section of a water-based ink sanding machine typically consists of a drive motor, a housing that holds the drive motor in place, and a sanding head. The sanding head is usually a high-speed rotating ball head with coarse abrasive particles, while the housing is fixed and does not rotate. Its movement is usually controlled by a CNC system, allowing for precise movement along the XYZ axes to sand the product surface according to preset patterns and paths.

[0004] The prior art patent CN213968245U discloses a dust removal device for a sanding machine used in the production of water-based inks, which includes a dust removal box, an operation box fixedly installed on one side of the top of the dust removal box, a first toothed plate slidably connected inside the operation box, and a fixed rod rotatably connected to the middle of the top of the dust removal box via a bearing.

[0005] However, the existing technology still has shortcomings in use: the existing technology uses the first rack plate to slide repeatedly in the horizontal direction, in conjunction with the gear shaft, which causes the fixed rod and the dust suction hood to swing repeatedly to perform dust suction. The dust suction hood can only swing within a fixed range, while the grinding head on the sanding machine can move precisely along a preset trajectory in the XYZ three-axis direction under the control of the CNC system. The fixed swing range of the dust suction hood cannot effectively follow the moving grinding head, causing dust to escape at the source. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the existing defects and provide a dust removal device for a water-based ink sanding machine. This device can effectively follow the moving sanding head, so that the dust collection surface can be closer to and always follow the dust source, thereby achieving source capture and efficient dust removal, which can effectively solve the problems in the background technology.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a dust removal device for a water-based ink sanding machine, comprising a dust removal box, an air pump installed at the bottom of the dust removal box, an exhaust pipe installed at the exhaust port of the air pump, and the exhaust pipe passing through a through hole opened on the side wall of the dust removal box, a dust filter core installed inside the dust removal box, and the dust filter core positioned above the air pump, a dust suction pipe assembly installed on the dust removal box, and two corresponding suction half-cylinders installed on the dust suction pipe assembly, the two suction half-cylinders being hinged together on the side near the dust suction pipe assembly by a pivot, a dust suction chamber being opened inside the suction half-cylinder, and several suction holes communicating with the dust suction chamber being evenly opened at the lower end of the suction half-cylinder, a latch being installed on the side of the suction half-cylinder away from the dust suction pipe assembly, the latches on the two suction half-cylinders cooperating with each other, and a block being installed inside the suction half-cylinder. A PLC controller is installed outside the dust collection box, and the output of the PLC controller is electrically connected to the input of the air pump. In use, first, open the latches on the two suction half-canisters, allowing them to rotate around the shaft and gradually separate. Install the separated suction half-canisters onto the housing used to fix the drive motor in the grinding section of the sander. The housing is fixed and does not rotate. Position the suction nozzles on the suction half-canisters slightly higher than the lowest point of the grinding head. Gradually bring the separated suction half-canisters back together until the mounting blocks on the two suction half-canisters contact and press against the housing, forming a complete cylindrical structure. Then, lock the latches on the two suction half-canisters together, completing the installation of the suction half-canisters. When the grinding head in the sander needs to grind the dried solid ink film, turn on the PLC controller. The PLC controller will then control the air pump to operate, and the air pump will remove... Air is expelled from the dust chamber, creating negative pressure inside the suction tube, L-shaped movable tube, suction pipe, Y-shaped suction pipe, and suction chamber. Dust generated during sanding is sucked into the suction chamber through the suction nozzle and suction holes. The dust entering the suction chamber passes sequentially through the Y-shaped suction pipe, suction pipe, L-shaped movable tube, and suction tube before entering the dust collection box and adhering to the dust filter element. When the sanding machine controls the sanding head to move along a preset trajectory in the XYZ three-axis direction via a CNC system, the suction pipe, being spiral-shaped and soft, can be stretched as the suction half-tube moves. Furthermore, the L-shaped movable tube and the suction tube are rotatably connected by a sealed bearing, achieving a seal during rotation. Ultimately, the suction half-tube effectively follows the moving sanding head, allowing the suction working surface to get closer to and always follow the dust source, thus achieving source capture and efficient dust removal.

[0008] Furthermore, a suction nozzle is provided at the lower end of the suction half-tube. The suction nozzle is closer to the source of dust generated during sanding, improving the dust removal effect.

[0009] Furthermore, the suction nozzle gradually extends inward and downward at an angle. This gradual inward and downward extension of the suction nozzle allows it to get closer to the source of dust generated during sanding, further improving the dust removal effect.

[0010] Furthermore, the suction pipe assembly is a rigid suction pipe fixedly installed on the suction port of the dust collection box. An L-shaped movable rigid pipe is rotatably connected to the upper end of the rigid suction pipe. The end of the L-shaped movable rigid pipe near the suction half-cylinder is sealed, and a suction pipe is installed at the sealed part of the L-shaped movable rigid pipe. The suction pipe communicates internally with the L-shaped movable rigid pipe. The suction pipe is made of flexible material and is connected to the suction chambers inside the two suction half-cylinders via a Y-shaped suction pipe, which is also made of flexible material. The dust collection box is connected to the suction chambers inside the two suction half-cylinders via the rigid suction pipe, the L-shaped movable rigid pipe, the suction pipe, and the Y-shaped suction pipe, facilitating the collection of generated dust onto the dust filter element in the dust collection box.

[0011] Furthermore, the inner walls of the suction pipe and the Y-shaped suction pipe are evenly spaced with several reinforcing rings. These reinforcing rings on the inner walls of the suction pipe and the Y-shaped suction pipe can support the soft suction pipe and the Y-shaped suction pipe, preventing them from flattening and affecting suction.

[0012] Furthermore, the suction tube has a spiral structure. The spiral structure of the suction tube facilitates its stretching.

[0013] Furthermore, a support rod is provided at one end of the L-shaped movable rigid tube near the suction half-tube, which cooperates with the suction tube. The support rod is hollow inside. The support rod can support the portion of the suction tube near the L-shaped movable rigid tube, and the hollow interior of the support rod can reduce weight.

[0014] Furthermore, the upper end of the vacuum suction tube is rotatably connected to the L-shaped movable tube via a sealed bearing. The sealed bearing enables the L-shaped movable tube to rotate around the vacuum suction tube while simultaneously providing a seal.

[0015] Furthermore, a fastening pad is provided on the inner side of the mounting block. The mounting block and the housing of the grinding part of the sander are rigidly pressed together, and the fastening pad can reduce the crushing damage when the mounting block is installed on the housing.

[0016] Based on the above technical solution, the beneficial effects achieved by the dust removal device for a water-based ink grinding machine through practical application are as follows: The interplay between the suction half-tube, mounting block, and locking buckle in this invention allows for convenient installation of two suction half-tubes onto the housing used to fix the drive motor in the grinding section of a sander. Simultaneously, because the suction pipe has a spiral structure and is made of soft material, it can be stretched when the suction half-tube moves. Furthermore, the L-shaped movable rigid pipe and the suction rigid pipe are rotatably connected via a sealed bearing, achieving a seal during rotation. Ultimately, when the sander, controlled by a CNC system, moves the grinding head along a preset trajectory in the XYZ axes, the suction half-tube effectively follows the moving grinding head, ensuring the dust collection surface is closer to and always follows the dust source, thus achieving source capture and efficient dust removal.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Please see Figure 1-8This embodiment provides a technical solution: a dust removal device for a water-based ink sanding machine, including a dust removal box 1, an air pump 15 is provided at the bottom of the dust removal box 1, an exhaust pipe 2 is provided at the exhaust port of the air pump 15, and the exhaust pipe 2 passes through a through hole opened on the side wall of the dust removal box 1, a dust filter element 14 is provided inside the dust removal box 1, and the dust filter element 14 is located above the air pump 15, a dust collection pipe assembly is provided on the dust removal box 1, and two corresponding dust collection half cylinders 9 are provided on the dust collection pipe assembly. The two dust collection half cylinders 9 are hinged by a pivot on the side near the dust collection pipe assembly. A dust collection chamber 17 is opened inside the dust collection half cylinder 9, and several dust collection holes 16 communicating with the dust collection chamber 17 are evenly opened at the lower end of the dust collection half cylinder 9. A latch 12 is provided on the side of the dust collection half cylinder 9 away from the dust collection pipe assembly. The latches 12 on the two dust collection half cylinders 9 cooperate with each other, and a block 10 is installed inside the dust collection half cylinder 9. A PLC controller is installed outside the dust collection box 1, and the output terminal of the PLC controller is electrically connected to the input terminal of the air pump 15. In use, first, open the latches on the two suction half-cylinders 9, allowing them to rotate around the shaft and gradually separate. Install the separated suction half-cylinders 9 onto the housing used to fix the drive motor in the grinding section of the sander. The housing is fixed and does not rotate. Position the suction nozzles on the suction half-cylinders 9 slightly higher than the lowest point of the grinding head. Gradually bring the separated suction half-cylinders 9 back together until the mounting blocks 10 on the two suction half-cylinders 9 contact and press against the housing, forming a complete cylindrical structure. Then, lock the latches 12 on the two suction half-cylinders 9 together, thus completing the installation of the suction half-cylinders 9. When the grinding head in the sander needs to grind the dried solid ink film, turn on the PLC controller. The PLC controller controls the air pump 15 to work, and the air pump 15 pumps the dust from the dust collection box 1... Air is expelled, creating negative pressure inside the suction tube 3, L-shaped movable tube 5, suction tube 7, Y-shaped suction tube 8, and suction chamber 17. Dust generated during sanding is drawn into the suction chamber 17 through the suction nozzle 13 and suction hole 16. The dust entering the suction chamber 17 then passes sequentially through the Y-shaped suction tube 8, suction tube 7, L-shaped movable tube 5, and suction tube 3, eventually entering the dust collection box 1 and adhering to the dust filter element 14 within it. The sanding machine uses a CNC system to control the sanding head's movement in the XY direction. When the Z-axis moves along the preset trajectory, the suction pipe 7 is spiral-shaped and soft, so the suction half-tube 9 can be stretched as it moves. The L-shaped movable rigid tube 5 and the suction rigid tube 3 are rotatably connected by a sealed bearing 4. While rotating, a seal can be achieved, so that the suction half-tube 9 can effectively follow the moving abrasive head, allowing the suction working surface to get closer to and always follow the dust source, thereby achieving source capture and efficient dust removal.

[0028] Furthermore, a suction nozzle 13 is provided at the lower end of the suction half-canister 9. The suction nozzle 13 is closer to the source of dust generated during sanding, improving the dust removal effect.

[0029] Furthermore, the suction nozzle 13 gradually extends inward and downward at an angle. This gradual inward and downward extension of the suction nozzle 13 allows it to get closer to the source of dust generated during sanding, further improving the dust removal effect.

[0030] Furthermore, the suction pipe assembly consists of a rigid suction pipe 3 fixedly mounted on the suction port of the dust collection box 1. An L-shaped movable rigid pipe 5 is rotatably mounted on the upper end of the rigid suction pipe 3. The end of the L-shaped movable rigid pipe 5 near the suction half-cylinder 9 is sealed, and a suction pipe 7 is mounted at the sealed end of the L-shaped movable rigid pipe 5. The suction pipe 7 is flexible and connected to the suction chambers 17 inside the two suction half-cylinders 9 via a Y-shaped suction pipe 8. The Y-shaped suction pipe 8 is also flexible. The dust collection box 1 is connected to the suction chambers 17 inside the two suction half-cylinders 9 via the rigid suction pipe 3, the L-shaped movable rigid pipe 5, the suction pipe 7, and the Y-shaped suction pipe 8, facilitating the collection of generated dust onto the dust filter element 14 in the dust collection box 1.

[0031] Furthermore, several reinforcing rings 18 are evenly spaced at equal intervals on the inner walls of the suction pipe 7 and the Y-shaped suction pipe 8. The reinforcing rings 18 on the inner walls of the suction pipe 7 and the Y-shaped suction pipe 8 can support the soft suction pipe 7 and the Y-shaped suction pipe 8, preventing the suction pipe 7 and the Y-shaped suction pipe 8 from flattening and affecting suction.

[0032] Furthermore, the suction pipe 7 has a spiral structure. The spiral structure of the suction pipe 7 makes it easy to stretch.

[0033] Furthermore, a support rod 6 is provided at one end of the L-shaped movable rigid tube 5 near the suction half-tube 9, which cooperates with the suction tube 7. The support rod 6 is hollow inside. The support rod 6 can support the part of the suction tube 7 near the L-shaped movable rigid tube 5. The hollow interior of the support rod 6 can reduce weight.

[0034] Furthermore, the upper end of the suction tube 3 is rotatably connected to the L-shaped movable tube 5 via a sealed bearing 4. The sealed bearing 4 can achieve a seal while allowing the L-shaped movable tube 5 to rotate around the suction tube 3.

[0035] Furthermore, a fastening pad 11 is provided on the inner side of the mounting block 10. The mounting block 10 is rigidly pressed onto the housing of the grinding part of the grinding machine, and the fastening pad 11 can reduce the crushing damage when the mounting block 10 is installed on the housing.

[0036] The working principle of the dust removal device for a water-based ink grinding machine provided by this utility model is as follows: In use, first open the latches on the two suction half-tubes 9, allowing them to rotate around the shaft and gradually separate. Install the separated suction half-tubes 9 onto the housing used to fix the drive motor in the sanding section of the sander. The housing is fixed and does not rotate. Position the suction nozzles on the suction half-tubes 9 slightly higher than the lowest point of the sanding head. Gradually bring the separated suction half-tubes 9 back together until the mounting blocks 10 on the two suction half-tubes 9 contact and press against the housing, forming a complete cylindrical structure. Then, lock the latches 12 on the two suction half-tubes 9 together, thus completing the installation of the suction half-tubes 9. When the sanding head in the sander needs to sand the dried solid ink film, turn on the PLC controller. The PLC controller controls the air pump 15 to work, and the air pump 15 discharges the air from the dust collection box 1, allowing the suction tube 3 and the L-shaped movable tube 5 to... A negative pressure is formed inside the suction pipe 7, the Y-shaped suction pipe 8, and the suction chamber 17. The dust generated by the sanding is sucked into the suction chamber 17 by the suction nozzle 13 and the suction hole 16. The dust entering the suction chamber 17 passes through the Y-shaped suction pipe 8, the suction pipe 7, the L-shaped movable rigid pipe 5, and the suction rigid pipe 3 in sequence, and enters the dust collection box 1, where it adheres to the dust filter element 14. When the sanding machine controls the sanding head to move along the preset trajectory in the XYZ three-axis direction through the CNC system, the suction pipe 7 can be stretched when the suction half-cylinder 9 moves along with it because the suction pipe 7 has a spiral structure and is made of soft material. The L-shaped movable rigid pipe 5 and the suction rigid pipe 3 are rotatably connected by a sealed bearing 4. While rotating, a seal can be achieved. Ultimately, the suction half-cylinder 9 effectively follows the moving sanding head, allowing the sanding surface to be closer to and always follow the dust source, thereby achieving source capture and efficient dust removal.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
