Description

Technical Field

[0001] This utility model relates to the field of filter bag manufacturing equipment, and in particular to a filter bag adhesive 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. This sewing process creates pinholes that can allow dust to pass through, affecting the overall filtration efficiency of the filter bag. 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.

[0003] Currently, there is a processing method that uses hot melt adhesive tape to adhere to the stitched area, which can ensure the uniform sealing of the pinholes. However, the tape is not sticky at room temperature and needs to be heated to ensure adhesion. Therefore, there is an urgent need for an adhesive applicator to achieve automatic tape application.

[0031] 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.

[0032] Please refer to Figures 1-4 This utility model provides a filter bag adhesive applicator, including a working platform 1, a machine base 2, an adhesive tape feeding assembly and a heating assembly 4;

[0033] The base 2 is disposed on the working platform 1. The base 2 is provided with a first connecting arm 21, a second connecting arm 22 and a drive arm 23; the first connecting arm 21 and the second connecting arm 22 are disposed on the same side.

[0034] The drive arm 23 includes a fixed base 231, a drive assembly 232, and a movable arm body 233; the lower end of the movable arm body 233 is provided with a drive wheel drive component 234, a first transmission wheel 235, and a drive wheel set, the first transmission wheel 235 and the drive wheel set are respectively rotatably mounted on the movable arm body 233, and the drive wheel drive component 234 drives the first transmission wheel 235 to rotate through the drive wheel set;

[0035] The fixed base 231 is disposed at one end of the first connecting arm 21, and the driving component 232 is disposed at the fixed base 231; the movable arm body 233 is connected to the driving component 232 in a transmission manner.

[0036] One end of the second connecting arm 22 is rotatably fitted with a second driven wheel 221. The second driven wheel 221 is located below the drive wheel assembly. The first transmission wheel 235 and the second driven wheel 221 cooperate to form a filter bag bonding station. The drive assembly 232 drives the movable arm 233 to move the first transmission wheel 235 closer to or away from the second driven wheel 221.

[0037] The tape feeding assembly and the heating assembly 4 are respectively fixed to the fixed base 231. The tape feeding assembly is used to provide hot melt adhesive tape 5 to the movable arm 233; the heating assembly 4 is used to heat the hot melt adhesive tape 5 at the filter bag bonding station with hot air.

[0038] The filter bag adhesive applicator is equipped with a base 2, a tape feeding assembly, and a heating assembly 4. The tape feeding assembly provides hot melt adhesive tape 5 to the filter bag bonding station, while the heating assembly 4 heats the hot melt adhesive tape 5 at the filter bag bonding station with hot air. In conjunction with the first drive wheel 235 and the second driven wheel 221, the hot melt adhesive tape 5 is pressed onto the filter bag, which can automatically apply adhesive to the outer periphery of the filter bag, replacing manual labor and improving the quality and efficiency of adhesive application.

[0039] When applying the adhesive, first, the filter bag is placed on the second driven wheel 221. Then, the drive assembly 232 is activated, causing the movable arm 233 to drive the first transmission wheel 235 closer to the second driven wheel 221, narrowing the distance between the first transmission wheel 235 and the second driven wheel 221, thereby clamping the hot melt adhesive tape 5 and the filter bag. Subsequently, the heating assembly 4 is activated to increase the temperature of the hot melt adhesive tape 5 at the filter bag bonding station, thus making that section of the hot melt adhesive tape 5 viscous. At the same time, the drive wheel set rotates, causing the first transmission wheel 235 to rotate, and the second transmission wheel 237 follows the first transmission wheel 235 to rotate, driving the filter bag to rotate. Since a portion of the hot melt adhesive tape 5 is bonded to the outer circumference of the filter bag, as the filter bag rotates, it will pull a new section of hot melt adhesive tape 5 through the air outlet of the heating assembly 4. The hot melt adhesive tape 5 that passes through the air outlet becomes viscous and is directly bonded to the filter bag. In this way, the hot melt adhesive tape 5 can be bonded around the outer circumference of the filter bag. After a full week of bonding, start the drive assembly 232 to make the movable arm 233 drive the first transmission wheel 235 away from the second driven wheel 221, and cut off the unbonded hot melt adhesive tape 5 to complete the bonding.

[0040] The drive wheel 234 is connected to the first transmission wheel 235 via the drive wheel set, so that the first transmission wheel 235 can rotate during the application of adhesive.

[0041] Specifically, the drive wheel assembly includes a drive wheel 236, a second transmission wheel 237, and a first driven wheel 238. The drive wheel 236, the second transmission wheel 237, and the first driven wheel 238 are rotatably connected to the movable arm 233. The drive wheel 236 is connected to the drive wheel drive component 234. The first transmission wheel 235 is located below the drive wheel 236, and the second transmission wheel 237 is located in front of the drive wheel 236. The sidewalls of the first transmission wheel 235 and the second transmission wheel 237 are in contact with the sidewall of the drive wheel 236. The first driven wheel 238 is located in front of the second transmission wheel 237 and forms a belt conveying gap for pulling the hot melt adhesive belt 5.

[0042] With the above structure, one driving wheel 236 can simultaneously drive the first transmission wheel 235 and the second transmission wheel 237 to rotate, resulting in a simple structure and cost savings. The first driven wheel 238 and the second transmission wheel 237 cooperate to form a belt conveying gap, which can pull the hot melt adhesive belt 5 so that the hot melt adhesive belt 5 can be conveyed out of the belt feeding assembly more quickly.

[0043] Furthermore, through the cooperation of the first drive wheel 235, the second drive wheel 237, the second driven wheel 221 and the first driven wheel 238, when bonding the outer periphery of the filter bag, the hot melt adhesive tape 5 can adhere to the outer side of the filter bag, reducing the problem of adhesive bulging.

[0044] In one specific embodiment of this utility model, the drive wheel 234 is a motor that drives the drive wheel 236 to rotate.

[0045] Specifically, the heating assembly 4 includes a hot air heating device 41, a fixed frame 42, a swing frame 43, and a swing drive 44; the fixed frame 42 is disposed on the fixed base 231, the swing drive 44 is disposed on the fixed frame 42, and the swing frame 43 is hinged to the fixed frame 42; the hot air heating device 41 is disposed on the swing frame 43, and the hot air heating device 41 includes a heating state and an idle state. When the hot air heating device 41 is in the heating state, the hot air heating device 41 is close to the filter bag bonding station; when the hot air heating device 41 is in the idle state, the hot air heating device 41 is away from the filter bag bonding station. The swing drive 44 drives the swing frame 43 to swing, so that the hot air heating device 41 switches between the heating state and the idle state.

[0046] The hot air heating device 41 can refer to existing hot air heating equipment. Through the cooperation of the fixed frame 42, the swing frame 43 and the swing drive component 44, the air outlet of the hot air heating device 41 can be driven to approach or move away from the filter bag bonding station, thereby switching the hot air heating device 41 between the heating state and the idle state, ensuring that the air outlet of the hot air heating device 41 can blow air accurately and not affect the rotation of the first drive wheel 235 and the second driven wheel 221 for adhesive application.

[0047] 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 air outlet of the hot air heating device 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 air outlet of the hot air heating device 41 to move closer to or away from the filter bag bonding station.

[0048] Furthermore, the hot air heating device 41 is provided with a hot air heating pipe, which is disposed on the swing frame 43. The heating component 4 also includes a temperature sensor 45, the detection end of which is disposed at the air outlet of the hot air heating pipe.

[0049] The hot air heating device 41 is equipped with a hot air heating pipe, and the bottom of the hot air heating pipe is provided with an air outlet facing the adhesive application area. The air outlet is driven by the swing frame 43 to move closer to or away from the filter bag bonding station. The temperature sensor 45 is used to detect the temperature of the air outlet of the hot air heating pipe to avoid the temperature being too low and affecting the adhesion of the hot melt adhesive tape 5.

[0050] Furthermore, the heating assembly 4 also includes a limiting member, which includes a baffle 46 and a connecting rod 47. One end of the connecting rod 47 is disposed on the fixing base 231, and the baffle 46 is disposed on the other end of the connecting rod 47. The baffle 46 has an inwardly recessed cavity that matches the shape of the end of the hot air heating pipe. When the hot air heating device 41 is in an idle state, the hot air heating pipe enters the cavity. When the hot air heating device 41 is in a heating state, the hot air heating pipe extends out of the cavity. The baffle 46 is provided with multiple heat dissipation holes.

[0051] With the above structure, the limiting component serves a protective function, preventing workers from accidentally touching the hot air heating element and getting burned. The connecting rod 47 functions as both the baffle 46 and the fixing base 231. The baffle 46 has multiple heat dissipation holes, which facilitates heat dissipation of the hot air heating element when it is not in use.

[0052] Preferably, the drive arm 23 further includes a limiting rod 239, which is disposed at the lower end of the movable arm body 233 and located on the front side of the drive wheel assembly. When the hot air heating device 41 is in the heating state, the hot air heating pipe is tightly pressed against the limiting rod 239.

[0053] The limiting rod 239, together with the limiting component, can limit the swing amplitude of the hot air heating tube, preventing the hot air heating tube from getting too close to the hot melt adhesive tape 5 when it is in the heating state, which would cause the hot melt adhesive tape 5 to become too hot and leak adhesive, affecting the bonding effect. It can also prevent the hot air heating tube from hitting the staff when it switches from the heating state to the idle state, thus preventing the staff from being injured and improving safety.

[0054] Specifically, the tape feeding assembly includes an unwinding reel 31, an unwinding frame 32, and a tape limiting plate 33. The unwinding frame 32 is mounted on a fixed base 231, and the unwinding reel 31 is rotatably mounted on the unwinding frame 32. The unwinding reel 31 is used to hold the hot melt adhesive tape 5. The tape limiting plate 33 is mounted on the movable arm 233 and is located above the tape conveying gap. The tape limiting plate 33 is provided with a tape conveying groove. After the hot melt adhesive tape 5 passes through the tape conveying groove, it enters the tape conveying gap.

[0055] The tape feeding assembly can refer to existing unwinding mechanisms. The unwinding reel 31 is used to hold the hot melt adhesive tape 5, and the unwinding frame 32 is used to connect the unwinding reel 31 and the fixing base 231. The tape limiting plate 33 serves to position the hot melt adhesive tape 5, allowing the hot melt adhesive tape 5 to smoothly enter the tape conveying gap and keeping the hot melt adhesive tape 5 straight, preventing the two sides of the hot melt adhesive tape 5 from bending inward and affecting the bonding effect.

[0056] 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.

[0057] 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.

[0058] 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.
