Description

Technical Field

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

[0002] The adhesive coating equipment used for filter bag processing is an automated device specifically designed for coating filter bag materials with adhesive. Its core function is to uniformly coat the filter bag surface with an adhesive layer to achieve process requirements such as sealing, waterproofing, and enhanced wear resistance.

[0003] The specific design and structure of coating equipment used for filter bag processing may vary depending on the manufacturer and application requirements, but generally they include the following key components: a glue storage tank, a glue supply pump, and a clamping mechanism. The glue storage tank is used to store the glue solution and is usually equipped with a stirring device to prevent the glue solution from settling. Some equipment also has a heating and insulation layer to maintain the flowability of the glue solution. The glue supply pump, through a gear pump, plunger pump, or peristaltic pump, delivers the glue solution from the storage tank to the coating head, and the flow rate can be adjusted to control the coating thickness. The clamping mechanism is designed for the bag-shaped structure in filter bag processing, using pneumatic grippers or mechanical clamps to fix the bag opening and body, preventing material movement during coating.

[0004] Traditional glue coating equipment used for filter bag processing often uses fixed clamps as its fixing mechanism, which can only accommodate filter bags of a single specification. When changing filter bags of different lengths or diameters, the clamps need to be disassembled manually, which is time-consuming and labor-intensive. Traditional glue coating equipment often uses a single-bucket glue supply. When the glue runs out, the machine needs to be stopped to replace the glue bucket, which seriously affects production efficiency. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a coating equipment for filter bag processing.

[0006] The technical solution adopted by this utility model to solve its technical problem is a coating equipment for filter bag processing, including a base, on which a vertically fixed cylinder is installed. Two vertical sliding holes are symmetrically opened on the wall of the fixed cylinder. An adjusting cylinder with a downward direction of action is installed on the inner wall of the top of the fixed cylinder, and an installation rod is fixed to the bottom of the adjusting cylinder. Two bidirectional cylinders are respectively installed on both sides of the center of the installation rod. The bidirectional cylinders are positioned with their direction of action facing the position of the sliding hole on one side, and the working end of the bidirectional cylinder moves through the sliding hole. The working rod of the bidirectional cylinder is perpendicular to the working rod of the adjusting cylinder. An arc-shaped fixing block is installed at the end of the working rod of the bidirectional cylinder. The arc-shaped fixing block is located outside the fixed cylinder, and the concave direction of the arc-shaped fixing block faces the fixed cylinder. A sliding groove is opened vertically inside the fixed cylinder, and the two ends of the installation rod are respectively slidably disposed inside the sliding groove.

Compared with traditional gravity glue supply or pump suction glue supply, this pneumatically driven glue supply method can more accurately control the extrusion speed and flow rate of the glue. By adjusting the pressure of the pressure cylinder, the glue supply can be flexibly adjusted according to different glue application process requirements, ensuring that the glue application head continuously and stably obtains the required glue, while reducing glue waste and improving glue utilization.

[0008] Preferably, the mounting bracket is provided with an adjustment rail, and a first transmission screw is rotatably mounted inside the adjustment rail. A positioning rod is provided on the side of the first transmission screw. An adhesive application slider is slidably mounted inside the adjustment rail. The adhesive application slider is provided with a threaded hole and a positioning hole. The first transmission screw rotates through the threaded hole on the adhesive application slider, and the positioning rod passes through the positioning hole on the adhesive application slider. A second motor bracket is provided at the top of the mounting bracket, and an adjustment motor is mounted on the second motor bracket. The output end of the adjustment motor is fixedly connected to the top of the first transmission screw.

[0011] Preferably, the rotary motor, the pressure cylinder, the regulating motor, and the glue-applying motor are all connected to an external controller. The controller is used to control the start and stop of the rotary motor, the pressure cylinder, the regulating motor, and the glue-applying motor. The controller can accurately control the start and stop, running speed, and working time of each power component according to a preset program or the operator's instructions.

[0012] The advantages of this utility model are: the adjusting cylinder drives the mounting rod to slide up and down along the slide groove, adjusts the axial position of the arc-shaped fixing block to adapt to the length difference of the filter bag, and at the same time the bidirectional cylinder pushes the arc-shaped fixing block to extend and retract radially, which can flexibly clamp and fix the opening of the filter bag.

The glue-pressing cylinder drives the extrusion plate to simultaneously extrude glue, achieving uninterrupted glue supply. When the glue in one bucket is used up, the other bucket is automatically replenished, avoiding the problem of having to stop the machine to change buckets when using traditional single-bucket glue supply, thus improving work efficiency.

[0017] Please see Figure 1-5 As shown, a coating device for filter bag processing includes a base 1, on which a vertically positioned fixed cylinder 30 is mounted. Two vertical sliding holes 36 are symmetrically formed on the wall of the fixed cylinder 30. A downward-facing adjusting cylinder 31 is mounted on the inner top wall of the fixed cylinder 30, and an installation rod 33 is fixed to the bottom of the adjusting cylinder 31. Two bidirectional cylinders 34 are mounted on either side of the center of the installation rod 33. The bidirectional cylinders 34 are positioned with their operating direction facing the sliding hole 36 on one side, and their operating ends movably penetrate into the sliding hole 36. The operating rods of the bidirectional cylinders 34 are perpendicular to the operating rods of the adjusting cylinder 31. An arc-shaped fixing block 35 is mounted at the end of the operating rod of the bidirectional cylinder 34.

[0018] During operation, in order to fix the filter bag, the operator puts the filter bag on the fixing cylinder 30, aligns the part of the filter bag that needs to be coated with glue with the glue applicator 23, starts the adjusting cylinder 31, and its output end pushes the mounting rod 33 down along the slide groove 32, so that the bidirectional cylinder 34 moves to the appropriate position. Then, the bidirectional cylinder 34 is started, which drives the two arc-shaped fixing blocks 35 to move closer to the fixing cylinder 30 to clamp the opening of the filter bag.

[0019] The base 1 is provided with a mounting bracket 2, the mounting bracket 2 is provided with a placement plate 3, the placement plate 3 is provided with a glue application bucket 4, the glue application bucket 4 is provided with a mounting plate 5 above the glue application bucket 4, the mounting plate 5 is provided with a pressure cylinder 6, the output end of the pressure cylinder 6 is provided with a squeezing plate 7, and the squeezing plate 7 is provided above the glue application bucket 4.

[0020] During operation, in order to replace the glue application bucket 4 without stopping the machine, when the controller controls the corresponding pressing cylinder 6 to extend to its maximum distance, it indicates that the glue in the glue application bucket 4 has been pushed out. At this time, the pressing cylinder 6 that has completed the operation is reset, and another pressing cylinder 6 is started to push the glue in the other single glue application bucket 4. The single glue application bucket 4 that has completed the glue delivery is replaced manually, and the working end of the corresponding pressing cylinder 6 is aligned with the matching glue delivery pipe 25 to complete the replacement.

[0021] The mounting bracket 2 is provided with an adjustment rail 8, and a first transmission screw 9 is rotatably installed inside the adjustment rail 8. A positioning rod 10 is provided on the side of the first transmission screw 9. A glue-applying slider 13 is slidably installed inside the adjustment rail 8. The glue-applying slider 13 is provided with a threaded hole and a positioning hole. The first transmission screw 9 rotates through the threaded hole on the glue-applying slider 13, and the positioning rod 10 passes through the positioning hole on the glue-applying slider 13. A second motor bracket 11 is provided at the top of the mounting bracket 2, and an adjustment motor 12 is provided on the second motor bracket 11. The output end of the adjustment motor 12 is fixedly connected to the top of the first transmission screw 9.

[0022] The glue-applying slider 13 has a glue-applying groove 14, and a second transmission screw 15 is rotatably arranged in the glue-applying groove 14.

[0023] The bottom end of the adjusting slider 16 is provided with a glue application tank 21. The two glue application tanks 4 are connected by a first glue delivery pipe 25. A second glue delivery pipe 24 is provided on the first glue delivery pipe 25. The other end of the second glue delivery pipe 24 is connected to the glue application tank 21. A glue application head 23 is provided on the glue application tank 21 through a fixing ring 22. A support column 38 is provided at the bottom end of the base 1.

[0024] The pressing cylinder 6, the adjusting motor 12, and the applying motor 19 are all connected to an external controller, which is used to control the start and stop of the pressing cylinder 6, the adjusting motor 12, and the applying motor 19.

[0025] During operation, in order to apply adhesive to the filter bags, the pressure cylinder 6 drives the extrusion plate 7 to squeeze the adhesive liquid in the coating tank 4 downwards. The two coating tanks 4 are connected in parallel through the first adhesive delivery pipe 25. The adhesive liquid flows into the coating chamber 21 through the first adhesive delivery pipe 25 and the second adhesive delivery pipe 24. The regulating motor 12 drives the first transmission screw 9 to rotate. The coating slider 13 cooperates with the first transmission screw 9 through the threaded hole and moves horizontally in the regulating rail 8 to accurately position the coating area along the length of the filter bag. The coating motor 19 drives the second transmission screw 15 to rotate, so that the regulating slider 16 moves in the coating groove 14. According to the thickness of the filter bag, the distance between the coating head 23 and the surface of the filter bag is automatically adjusted.

[0026] Working principle: In order to fix the filter bag, the operator puts the filter bag on the fixing cylinder 30, and at the same time aligns the part of the filter bag that needs to be glued with the glue applicator 23. The adjusting cylinder 31 is started, and its output end pushes the mounting rod 33 down along the slide groove 32, so that the bidirectional cylinder 34 moves to the appropriate position. Then the bidirectional cylinder 34 is started, which drives the two arc-shaped fixing blocks 35 to move closer to the fixing cylinder 30 to clamp the opening of the filter bag, so as to ensure that the glue application trajectory of the filter bag is aligned with the movement trajectory of the glue applicator 23.

[0027] In order to apply glue to the filter bag, the pressure cylinder 6 applies pressure evenly to the extrusion plate 7 according to the output of the glue application head 23, so that the extrusion plate 7 presses down the glue in the glue application tank 4, which can ensure that the glue output speed is uniform. Valves are installed on the two No. 1 glue delivery pipes 25 respectively, so that when the glue application tank 4 is replaced on one side, the No. 1 glue delivery pipe 25 connected to it can be closed to ensure that other glue materials are accurately delivered to the glue application head 23. Two glue-coating buckets 4 are connected in parallel through glue delivery pipe 25. The glue flows into the glue-coating chamber 21 through glue delivery pipe 25 and glue delivery pipe 24. The regulating motor 12 drives the first transmission screw 9 to rotate. The glue-coating slider 13 cooperates with the first transmission screw 9 through the threaded hole and moves horizontally in the regulating rail 8 to accurately position the glue-coating area along the length of the filter bag. The glue-coating motor 19 drives the second transmission screw 15 to rotate, so that the regulating slider 16 moves in the glue-coating trough 14. The glue-coating head 23 is adjusted to have a suitable glue-coating distance from the surface of the filter bag to ensure that the glue discharged evenly can accurately adhere to the filter bag without causing glue overflow or falling off. When the controller controls the corresponding pressing cylinder 6 to extend to its maximum distance, it indicates that the adhesive in the coating bucket 4 has been pushed out. At this time, the pressing cylinder 6 that has completed the operation will be reset, and another pressing cylinder 6 will be started to push the adhesive in another single coating bucket 4. The single coating bucket 4 that has completed the adhesive delivery can be replaced manually, and the working end of the corresponding pressing cylinder 6 will be aligned with the matching first adhesive delivery pipe 25 to complete the replacement.
