Description

Technical Field

[0001] This utility model relates to the field of filter bag manufacturing equipment, and in particular to a filter bag applicator. Background Technology

[0002] Filter bags are a common consumable in baghouse dust collectors. They are generally made of non-woven fabric and consist of a bottom and a body. The bottom and body, as well as the body and opening, are usually sewn together.

The current practice is to manually apply adhesive to the sewn area after sewing to seal the pinholes. However, this method is cumbersome, requires manual labor, and the adhesive application is not always even. Utility Model Content

[0040] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] Please refer to Figures 1-6 This utility model provides a filter bag applicator, including a working platform 1, a machine base 2, a feeding and pressing mechanism 3, and a hot melt adhesive discharging mechanism 4;

[0042] The base 2 is disposed on the working platform 1, and the base 2 is provided with a first connecting arm 21 and a second connecting arm 22; the first connecting arm 21 and the second connecting arm 22 are disposed on the same side; the feeding and pressing mechanism 3 includes a strip feeding assembly and a pressing assembly, the strip feeding assembly and the pressing assembly are respectively disposed on the first connecting arm 21, the strip feeding assembly is used to provide a leak-proof strip 5; the pressing assembly cooperates with the second connecting arm 22 to form a filter bag bonding station, the filter bag bonding station is used to press the leak-proof strip 5 onto the outer periphery of the filter bag.

[0043] The hot melt adhesive dispensing mechanism 4 includes a hot melt adhesive extrusion assembly 41, a fixed frame 42, a swing frame 43, and a swing drive component 44; the fixed frame 42 is disposed on the first connecting arm 21 and is located on one side of the pressing assembly;

[0044] The swing drive 44 is mounted on the fixed frame 42, and the swing frame 43 is hinged to the fixed frame 42. The hot melt adhesive dispensing mechanism 4 includes a working state and an idle state. When the hot melt adhesive dispensing mechanism 4 is in the working state, the hot melt adhesive extrusion assembly 41 is close to the filter bag bonding station. When the hot melt adhesive dispensing mechanism 4 is in the idle state, the hot melt adhesive extrusion assembly 41 is away from the filter bag bonding station. The swing drive 44 drives the swing frame 43 to swing, so that the hot melt adhesive dispensing mechanism 4 switches between the working state and the idle state. The hot melt adhesive extrusion assembly 41 is mounted on the swing frame 43 and is used to extrude hot melt adhesive onto the leak-proof cloth strip 5.

[0045] Through the cooperation of the fixed frame 42, the swing frame 43 and the swing drive 44, the hot melt adhesive extrusion assembly 41 can be driven to approach or move away from the filter bag bonding station, thereby switching the hot melt adhesive extrusion assembly 41 between working state and idle state, ensuring that the hot melt adhesive extrusion assembly 41 can extrude hot melt adhesive to the leak-proof cloth strip 5.

[0046] In a specific embodiment of this utility model, the swing drive 44 is a cylinder, the driving end of the swing drive 44 is a cylinder shaft, and a transmission rod is hinged to the end of the cylinder shaft. The other end of the transmission rod is hinged to the swing frame 43. Since the swing frame 43 is hinged to the fixed frame 42, and the hot melt adhesive extrusion assembly 41 is fixed to the swing frame 43, the swing drive 44 drives the swing frame 43 to swing through the transmission rod, thereby driving the hot melt adhesive extrusion assembly 41 to move closer to or away from the filter bag bonding station.

[0047] The filter bag applicator is equipped with a base 2, a feeding and pressing mechanism 3, and a hot melt adhesive dispensing mechanism 4. The hot melt adhesive dispensing mechanism 4 extrudes hot melt adhesive onto the leak-proof strip 5 at the filter bag bonding station, while the feeding and pressing mechanism 3 provides the leak-proof strip 5 to the filter bag bonding station and presses the leak-proof strip 5 coated with hot melt adhesive onto the filter bag. This structure allows for automatic adhesive application to the outer periphery of the filter bag, reducing manual operation, resulting in more uniform hot melt adhesive application and improving the quality and efficiency of the application.

[0048] Specifically, the hot melt adhesive extrusion assembly 41 includes a connecting rod 411, a mounting box 412, a hot melt adhesive discharging unit 413, and an X-axis drive assembly 414;

[0049] One end of the connecting rod 411 is fixed to the swing frame 43, and the mounting box 412 is fixed to the other end of the connecting rod 411;

[0050] The hot melt adhesive dispensing unit 413 and the X-axis drive assembly 414 are respectively disposed in the mounting box 412. The mounting box 412 is provided with an avoidance opening 4121 on the side facing the filter bag bonding station; the mounting box 412 is provided with a hot melt adhesive strip inlet 4122 on the side facing away from the filter bag bonding station.

[0051] The outlet of the hot melt adhesive dispensing unit 413 extends from the relief opening 4121 and is used to extrude hot melt adhesive onto the leak-proof cloth strip 5.

[0052] The X-axis drive assembly 414 is used to drive the hot melt adhesive dispensing unit 413 to move along the X-axis direction.

[0053] The width direction of the leak-proof strip 5 is the X-axis. When the hot melt adhesive dispensing mechanism 4 is in working condition, the outlet of the hot melt adhesive dispensing unit 413 extends from the clearance opening 4121 and the outlet of the hot melt adhesive dispensing unit 413 is close to the filter bag bonding station. The hot melt adhesive dispensing unit 413 squeezes the hot melt adhesive onto the surface of the leak-proof strip 5. At this time, the X-axis drive assembly 414 drives the hot melt adhesive dispensing unit 413 to move along the width direction of the leak-proof strip 5. Since the leak-proof strip 5 is continuously output from the strip feeding assembly to the filter bag bonding station to wrap around the outer periphery of the filter bag, the hot melt adhesive dispensing unit 413 can leave a wavy path of hot melt adhesive on the leak-proof strip 5.

[0054] The above structure enables the hot melt adhesive to form a wavy path, resulting in a wider distribution of the hot melt adhesive. This increases the contact area between the hot melt adhesive and the leak-proof strip 5, improves adhesion, and makes the leak-proof strip 5 bond more tightly to the filter bag, thereby reducing the probability of leakage.

[0055] The connecting rod 411 is used to connect the mounting box 412, thereby enabling the mounting box 412 to move closer to or further away from the filter bag bonding station. The mounting box 412 is used to house the hot melt adhesive dispensing unit 413 and the X-axis drive assembly 414. The hot melt adhesive dispensing unit 413 is used to extrude hot melt adhesive onto the leak-proof fabric strip 5.

[0056] Specifically, the X-axis drive assembly 414 includes an X-axis drive device 401, an X-axis slider 402, and an X-axis slide rail 403;

[0057] The X-axis drive device 401 and the X-axis slide rail 403 are respectively disposed in the mounting box 412, and the X-axis drive device 401 is located on one side of the X-axis slide rail 403. The X-axis slider 402 is slidably mounted on the X-axis slide rail 403. The drive end of the X-axis drive device 401 is connected to the X-axis slider 402 in a transmission manner. The hot melt adhesive dispensing unit 413 is disposed on the X-axis slider 402.

[0058] With the above structure, the X-axis slider 402 is driven by the X-axis drive device 401 to reciprocate on the X-axis slide rail 403, thereby achieving the purpose of moving the hot melt adhesive dispensing unit 413 along the X-axis direction. In a specific embodiment of this utility model, the X-axis drive device 401 is a reciprocating motor.

[0059] Specifically, the hot melt adhesive dispensing unit 413 includes a fixed base 404, an adhesive strip mounting base 405, a heating tube 406, and a Y-axis drive device 407;

[0060] The fixed base 404 is disposed on the X-axis slider 402, and the fixed base 404 is provided with a Y-axis groove 408 along the Y-axis direction. The adhesive strip mounting seat 405 is slidably assembled in the Y-axis groove 408. The Y-axis drive device 407 is disposed at one end of the fixed base 404 near the hot melt adhesive strip inlet 4122, and the drive end of the Y-axis drive device 407 is connected to the adhesive strip mounting seat 405. The adhesive strip mounting seat 405 is used to fix the hot melt adhesive strip 409. The Y-axis drive device 407 is used to press the hot melt adhesive strip into the heating tube 406.

[0061] The hot melt adhesive dispensing unit 413 can refer to the hot melt adhesive extrusion structure of existing hot melt glue guns. A hot melt adhesive strip 409 is inserted into the mounting box 412 through the hot melt adhesive strip inlet 4122 and fixed to the adhesive strip mounting base 405. The Y-axis drive device 407 drives the adhesive strip mounting base 405 to move along the Y-axis in the Y-axis groove 408, thereby causing the hot melt adhesive strip 409 to enter the heating tube 406. A heating device is provided on the outer periphery of the heating tube 406, capable of melting the hot melt adhesive strip 409 from a strip-shaped solid into a gel-like substance. As the Y-axis drive device 407 continuously presses the hot melt adhesive strip 409 into the heating tube 406, the gel-like hot melt adhesive is extruded from the outlet of the heating tube 406. The outlet of the heating tube 406 extends from the clearance opening 4121; therefore, when the mounting box 412 approaches the filter bag bonding station, the outlet of the heating tube 406 can extrude hot melt adhesive into the leak-proof cloth strip 5.

[0062] The above structure is simple and easy to operate, facilitating bonding operations for workers. Once the hot melt adhesive strip 409 is used up, it can be replenished through the hot melt adhesive strip inlet 4122.

[0063] Furthermore, the pressing assembly includes a connecting seat 301, a driving assembly 302, and a movable arm 303; the connecting seat 301 is disposed at one end of the first connecting arm 21, and the driving assembly 302 is disposed on the connecting seat 301; the movable arm 303 is connected to the driving assembly 302 in a transmission manner.

[0064] The lower end of the movable arm 303 is provided with an active wheel drive 304, a first transmission wheel 305 and a drive wheel set. The first transmission wheel 305 and the drive wheel set are rotatably mounted on the movable arm 303. The active wheel drive 304 drives the first transmission wheel 305 to rotate through the drive wheel set.

[0065] One end of the second connecting arm 22 is rotatably fitted with a first driven wheel 221. The first driven wheel 221 is located below the drive wheel assembly. The first transmission wheel 305 and the first driven wheel 221 cooperate to form a filter bag bonding station. The drive assembly 302 drives the movable arm 303 to move the first transmission wheel 305 closer to or away from the first driven wheel 221.

[0066] When applying adhesive, the filter bag is first placed on the first driven wheel 221, and then the drive assembly 302 is activated, causing the movable arm 303 to drive the first transmission wheel 305 closer to the first driven wheel 221, narrowing the distance between the first transmission wheel 305 and the first driven wheel 221, thereby clamping the leak-proof strip 5 and the filter bag. At the same time, the hot melt adhesive dispensing unit 413 is activated and moved closer to the filter bag bonding station, so that the hot melt adhesive dispensing unit 413 extrudes hot melt adhesive onto the leak-proof strip 5. Subsequently, the drive wheel assembly is driven to rotate, causing the first transmission wheel 305 to rotate, and the first driven wheel 221 to rotate with the first transmission wheel 305, driving the filter bag to rotate. Since a part of the leak-proof strip 5 is bonded to the outer periphery of the filter bag, when the filter bag rotates, it will pull a new section of the leak-proof strip 5 into the filter bag bonding station.

[0067] Using the above method, the leak-proof strip 5 can be bonded around the outer periphery of the filter bag. After a complete circumference of bonding, the drive assembly 302 is activated, causing the movable arm 303 to drive the first transmission wheel 305 away from the first driven wheel 221, and the unbonded leak-proof strip 5 is cut off, thus completing the bonding process.

[0068] The drive wheel 304 is connected to the first transmission wheel 305 via the drive wheel set, enabling the first transmission wheel 305 to rotate during the adhesive application process.

[0069] Furthermore, the drive wheel assembly includes a drive wheel 306, a second transmission wheel 307, and a second driven wheel 308. The drive wheel 306, the second transmission wheel 307, and the second driven wheel 308 are rotatably connected to the movable arm 303. The drive wheel 306 is connected to the drive wheel drive component 304. The first transmission wheel 305 is located below the drive wheel 306, and the second transmission wheel 307 is located in front of the drive wheel 306. The sidewalls of the first transmission wheel 305 and the second transmission wheel 307 are in contact with the sidewall of the drive wheel 306. The second driven wheel 308 is located in front of the second transmission wheel 307 and forms a belt conveying gap for pulling the leak-proof cloth strip 5.

[0070] With the above structure, one driving wheel 306 can simultaneously drive the first transmission wheel 305 and the second transmission wheel 307 to rotate, which is simple in structure and saves costs. The second driven wheel 308 cooperates with the second transmission wheel 307 to form a belt conveying gap, which can pull the leak-proof cloth strip 5 so that the leak-proof cloth strip 5 can be conveyed out of the cloth strip feeding assembly more quickly.

[0071] Moreover, through the cooperation of the first drive wheel 305, the second drive wheel 307, the first driven wheel 221 and the second driven wheel 308, when the outer periphery of the filter bag is pressed, the leak-proof strip 5 can adhere to the outer side of the filter bag, reducing the problem of sticking bulges.

[0072] In one specific embodiment of this utility model, the drive wheel 304 is a motor that drives the drive wheel 306 to rotate.

[0073] Optionally, the pressing assembly further includes a limiting rod 309, which is disposed at the lower end of the movable arm 303 and located on the front side of the drive wheel assembly. When the hot melt adhesive extrusion assembly 41 is in working condition, the connecting rod 411 abuts against the limiting rod 309.

[0074] The limiting rod 309 and the limiting component work together to limit the swing amplitude of the connecting rod 411, preventing the discharge tower of the hot melt adhesive discharge unit 413 from getting too close to the leak-proof cloth strip 5 when it is in operation, which would affect the extrusion of the hot melt adhesive and thus avoid a reduction in the bonding effect.

[0075] Specifically, the fabric feeding assembly includes an unwinding reel 310, an unwinding frame 311, and a tape limiting plate 312. The unwinding frame 311 is disposed on the connecting seat 301, and the unwinding reel 310 is rotatably mounted on the unwinding frame 311. The unwinding reel 310 is used to place the leak-proof fabric strip 5. The tape limiting plate 312 is disposed on the movable arm 303 and is located above the tape conveying gap. The tape limiting plate 312 is provided with a tape conveying groove. After the leak-proof fabric strip 5 passes through the tape conveying groove, it enters the tape conveying gap.

[0076] The fabric feeding assembly can refer to the existing unwinding mechanism. The unwinding reel 310 is used to place the leak-proof fabric strip 5, and the unwinding frame 311 is used to connect the unwinding reel 310 and the connecting seat 301. The tape limiting plate 312 plays the role of positioning the leak-proof fabric strip 5, so that the leak-proof fabric strip 5 can smoothly enter the tape conveying gap and keep the leak-proof fabric strip 5 straight, preventing the two sides of the leak-proof fabric strip 5 from bending inward and affecting the bonding effect.

[0077] Optionally, it also includes a lighting lamp 6, the fixed end of which is disposed on the first connecting arm 21, and the lighting end of the lighting lamp 6 faces the filter bag bonding station.

[0078] With the above structure, the filter bag bonding station is illuminated by the lighting lamp 6, which provides supplemental lighting to facilitate the staff's observation of the filter bag bonding status, timely detection of problems, reduction of the occurrence of a large number of defective products, and lowering of the defect rate.

[0079] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
