Description

Technical Field

[0001] This utility model belongs to the field of spraying technology for filter bag production, specifically a spraying equipment for filter bag production. Background Technology

[0002] Spraying equipment refers to specialized tools used to cover metal and non-metal surfaces with protective or decorative layers. It controls the airflow to instantly drive the air distribution reversing device to reverse the direction, thereby causing the piston of the pneumatic motor to make a stable and continuous reciprocating motion, which pressurizes the inhaled paint. The paint is then delivered to the spray gun of the spraying machine through a high-pressure hose, and the paint is instantly atomized and released onto the surface of the object being coated. In order to improve the durability and filtration effect of filter bags, a spraying equipment for filter bag production is needed.

[0003] The existing spraying device includes: a spraying box, a spraying structure, a pressing and moving structure, a spray head and nozzle, and a control system. It flattens one end of the filter bag and passes it between the pressure rollers to ensure that the filter bag does not wrinkle during the spraying process. The motor drives the spray head to swing back and forth, and an external liquid pump provides spraying material. The spray head sprays the filter bag surface evenly, while the pressure rollers move the filter bag slowly to ensure that the entire surface is evenly covered with spraying material.

[0004] However, existing spraying equipment still has some problems. When the pressure roller is used to fix one end of the filter bag, the pressure roller will block a certain part of the outer surface of the filter bag during the spraying process, which will affect the quality of the filter bag spraying. Therefore, a spraying equipment for filter bag production is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a spraying device for filter bag production.

[0006] The technical solution adopted by this utility model to solve its technical problem is a spraying equipment for filter bag production, including: a workbench, a dust cover fixedly connected to the upper surface of the workbench, a dust curtain threadedly connected to one side of the dust cover, a magnetic strip fixedly connected to one side of the dust curtain, a first drive motor installed on the top of the dust cover, a main gear fixedly connected to the output end of the first drive motor, a secondary gear meshing with the main gear, one end of the secondary gear rotatably connected to the inside of the dust cover, a connecting frame threadedly connected to the lower surface of the secondary gear, the connecting frame rotatably connected to the inside of the dust cover, a cylinder installed on the lower surface of the connecting frame, a support frame fixedly connected to the lower surface of the connecting frame, the support frame located outside the cylinder, an adjusting frame fixedly connected to the telescopic end of the cylinder, a connecting rod hinged to the support frame, an inner support plate hinged to one end of the connecting rod, two sets of dust curtains blocking the opening side of the dust cover, and the position of the dust curtains being fixed by the attraction of two sets of magnetic strips, which can prevent the spray material from spreading outward during the filter bag spraying process.

[0007] Preferably, an anti-slip pad is fixedly connected to one side of the inner support plate, and a telescopic slide rod is hinged to one side of the inner support plate. One end of the telescopic slide rod is hinged to one side of the adjustment frame. The anti-slip pad can increase the friction with the inner wall of the filter bag, thereby improving the fixing strength of the filter bag.

[0008] Preferably, a spray box is fixedly connected to the lower surface of the workbench, a feeding port is provided on one side of the spray box, a pump is installed on one side of the spray box, and a transmission pipe is threadedly connected to the pump and the spray box. By operating the pump, the spray material inside the spray box can be drawn into the spray gun for use through the transmission pipe.

[0009] Preferably, a second drive motor is installed on the top of the dust cover, and a bidirectional screw is fixedly connected to the output end of the second drive motor. One end of the bidirectional screw is rotatably connected to the inside of the worktable. The bidirectional screw can be driven to rotate by the operation of the second drive motor.

[0010] Preferably, an adjusting block is threadedly connected to the bidirectional screw, the transmission pipe is connected to the adjusting block, and a spray gun is threadedly connected to one end of the adjusting block. Because the adjusting block has an internal thread that matches the thread of the bidirectional screw, the spray height can be adjusted when the bidirectional screw rotates.

[0011] Preferably, the spraying equipment is equipped with an external controller, which is used to control the start and stop of the first drive motor, cylinder, material pump, second drive motor and spray gun. By controlling the first drive motor, cylinder, material pump, second drive motor and spray gun through the external controller, the ease of use of the spraying equipment is improved.

[0012] The advantages of this invention are as follows: by pushing one end of the adjusting frame and the telescopic slide rod downwards using a cylinder, the telescopic slide rod is tilted to a horizontal position, thereby pushing the inner support plate outwards and causing the two sets of connecting rods to rotate synchronously, so that the inner support plate is in a vertical position. This allows for internal support and fixation of the inner wall of the filter bag opening, thus securing the filter bag to be sprayed. During the spraying process, this avoids obstructing the surface of the dust collector filter bag when it is secured, thereby improving the spraying quality of the dust collector filter bag surface.

[0013] This invention uses a spray gun to spray coating material onto the surface of the filter bag. Because the spraying speed of the spray gun is matched with the rotation speed of the rotating component, the spray gun can complete the coating at the same height by spraying layer by layer. After the spray gun stops working, it is driven by the double screw of the spray gun to descend to the second height, and then the spray gun starts again to spray the dust collector filter bag. Since the spraying time cycle is the same as the rotation cycle of the dust collector filter bag, the time for the dust collector filter bag and the spray gun to spray are the same, thereby improving the comprehensiveness of the filter bag coating.

[0017] 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 scope of protection of the present utility model.

[0018] Please see Figure 1-5 As shown, a spraying device for filter bag production includes: a workbench 1, a dust cover 2 fixedly connected to the upper surface of the workbench 1, a dust curtain 3 threadedly connected to one side of the dust cover 2, a magnetic strip 4 fixedly connected to one side of the dust curtain 3, a first drive motor 5 mounted on the top of the dust cover 2, a main gear 6 fixedly connected to the output end of the first drive motor 5, a secondary gear 7 meshing with the main gear 6, one end of the secondary gear 7 rotatably connected inside the dust cover 2, and a connecting frame 8 threadedly connected to the lower surface of the secondary gear 7. The connecting frame 8 is rotatably connected to the inside of the dust cover 2. A cylinder 9 is installed on the lower surface of the connecting frame 8. A support frame 10 is fixedly connected to the lower surface of the connecting frame 8. The support frame 10 is located outside the cylinder 9. An adjusting frame 11 is fixedly connected to the telescopic end of the cylinder 9. A connecting rod 12 is hinged on the support frame 10. An inner support plate 13 is hinged to one end of the connecting rod 12. An anti-slip pad is fixedly connected to one side of the inner support plate 13. A telescopic slide rod 14 is hinged to one side of the inner support plate 13. One end of the telescopic slide rod 14 is hinged to one side of the adjusting frame 11. The paint is instantly atomized by the spray gun 20 and released onto the surface of the filter bag. To improve the durability and filtration effect of the filter bag, a spraying device for filter bag production is needed. In actual use, the filter bag to be sprayed is placed over the inner support plate 13. The cylinder 9 is started by the external controller, pushing the adjusting frame 11 downward, which drives the end of the telescopic slide rod 14 connected to it to move downward synchronously, reducing the tilt angle of the telescopic slide rod 14. This pushes the inner support plate 13 and the anti-slip pad outward through the connection between the telescopic slide rod 14 and the inner support plate 13. Subsequently, the inner support plate 13 drives one end of the connecting rod 12 to move upward, so that the connecting rod 12 and the telescopic slide rod 14 rotate synchronously, which improves the uniformity of force on the inner support plate 13. After the cylinder 9 pushes the adjusting frame 11 downward a certain length, the cylinder 9 is closed by the external controller, so that the inner support plate 13 and the anti-slip pad are in contact with the inner surface of the filter bag to be sprayed. The combination of 13 and three sets of protective pads provides outward support for the filter bag opening, preventing the internal support structure from obstructing the filter bag's spraying surface during the spraying process, thereby improving the quality of the filter bag spraying. After the filter bag is fixed inside the dust cover 2, the first drive motor 5 is started by the external controller, driving the main gear 6 to rotate. Because the main gear 6 and the auxiliary gear 7 mesh, when the main gear 6 rotates, the fixed filter bag rotates synchronously through the auxiliary gear 7, the connecting frame 8, and the support frame 10. This allows the spray gun 20 to spray the filter bag at the same height while it is spraying. After the same height is completely sprayed, the spray gun 20 stops working and rotates in conjunction with the bidirectional screw 18, causing the spray gun 20 to move down a certain distance, changing the spraying position on the filter bag and continuing to spray. The spraying time cycle is the same as the rotation cycle of the dust collector filter bag, thus enabling layer-by-layer spraying of the dust collector filter bag surface, thereby improving the comprehensiveness of the filter bag spraying.

[0019] Please see Figure 1-5 As shown, a spray box 21 is fixedly connected to the lower surface of the workbench 1. A feeding port is opened on one side of the spray box 21. A pump 15 is installed on one side of the spray box 21. A transmission pipe 16 is threadedly connected to the pump 15 and the spray box 21. A second drive motor 17 is installed on the top of the dust cover 2. A bidirectional screw 18 is fixedly connected to the output end of the second drive motor 17. One end of the bidirectional screw 18 is rotatably connected to the inside of the workbench 1. An adjusting block 19 is threadedly connected to the bidirectional screw 18. The transmission pipe 16 is connected to the adjusting block 19. A spray gun 20 is threadedly connected to one end of the adjusting block 19. The spraying equipment is externally connected to a controller. The external controller is used to control the start and stop of the first drive motor 5, cylinder 9, pump 15, second drive motor 17 and spray gun 20. After the filter bag is fixed inside the dust cover 2, the second drive motor 17 is started by the external controller, which drives the bidirectional screw 18 to rotate. Since the adjusting block 19 has an internal thread that matches the thread of the bidirectional screw 18, the height of the adjusting block 19 can be adjusted when the bidirectional screw 18 rotates. This causes one end of the transmission pipe 16 and the spray gun 20 to move synchronously. Since the spraying area of ​​the spray gun 20 is fixed, the distance that the spray gun 20 moves down or up is the same as the spraying area, so that the spraying of the spray gun 20 is in the form of layer-by-layer spraying. This works with the main gear 6 and the auxiliary gear 7 to ensure that the contact time between the dust collector filter bag surface and the spray material is the same. By starting the material pump 15 and the spray gun 20 by the external controller, the spray material in the spray box 21 can be drawn into the spray gun 20 through the transmission pipe 16. The spray gun 20 sprays the spray material onto the surface of the filter bag, thus improving the comprehensiveness of the filter bag spraying in conjunction with the rotating component.

[0020] Working principle: The filter bag to be sprayed is placed over the inner support plate 13. The cylinder 9 is activated via an external controller, pushing the adjusting frame 11 downwards. This causes the end of the telescopic slide rod 14 connected to it to move downwards synchronously. This pushes the inner support plate 13 and the anti-slip pad outwards through the connection between the telescopic slide rod 14 and the inner support plate 13. Subsequently, the inner support plate 13 drives one end of the connecting rod 12 upwards, causing the connecting rod 12 and the telescopic slide rod 14 to rotate synchronously, thus improving the uniformity of force on the inner support plate 13. The cylinder 9 is then deactivated via the external controller, allowing the inner support plate 13 and the anti-slip pad to contact the inner surface of the filter bag to be sprayed. The three sets of inner support plates 13 and three sets of protective pads work together to expand and support the filter bag opening outwards. The first drive motor 5 is activated via the external controller, driving the main gear 6 to rotate, which in turn drives the auxiliary gear... Gear 7, connecting frame 8, and support frame 10 drive the fixed filter bag to rotate synchronously. Then, the second drive motor 17 is started by the external controller, which drives the bidirectional screw 18 to rotate. The height adjustment of the adjusting block 19 and the spray gun 20 is achieved by starting the material pump 15 and the spray gun 20 through the external controller. The spray paint in the spray box 21 is then drawn into the spray gun 20 through the transmission pipe 16. The spray gun 20 sprays the paint onto the surface of the filter bag. Because the spraying speed of the spray gun 20 matches the rotation speed of the rotating components, the spray gun 20 can complete the coating at the same height by spraying layer by layer. After the spray gun 20 stops working, it is driven by the bidirectional screw 18 to descend to the second height and then spraying resumes. The spraying time cycle is the same as the rotation cycle of the dust collector filter bag, thereby improving the comprehensiveness of the filter bag coating.
