[0001] This utility model belongs to the field of filter bag production technology, and relates to a steel ring sleeve device for a filter bag sewing production line. Background Technology

[0002] The filter bag possesses excellent chemical stability and heat resistance, representing the highest performance in the filter media industry and the most advanced variety among all commonly used filter materials, achieving high levels of filtration efficiency and precision. In the filter bag production process, after the filter media is cut into sections, it needs to be adhered to the surface of the steel ring. This requires a specialized fitting device; therefore, designing a steel ring fitting device for a filter bag sewing production line is essential. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a steel ring feeding device for a filter bag sewing production line.

[0004] The objective of this utility model can be achieved through the following technical solution: A steel ring feeding device for a filter bag sewing production line, comprising a frame, characterized in that a guide strip is fixedly installed in the middle section of the frame as the feeding end, a first conveyor wheel assembly is installed above the guide strip, a second conveyor wheel assembly is installed horizontally behind the first conveyor wheel assembly, and a glue application mechanism is installed between the second conveyor wheel assembly and the first conveyor wheel assembly. The glue application mechanism includes a glue wheel and a glue box, the glue box is installed below the second conveyor wheel assembly and the first conveyor wheel assembly, and the glue wheel is installed inside the glue box. The top of the rubber wheel is slightly higher than the height of the guide bar. A pressing mechanism for pressing the filter material and the steel ring is installed behind the second conveyor wheel assembly. The pressing mechanism includes a support wheel and a pressing wheel. The support wheel is installed behind the second conveyor wheel assembly and connected to a rotary motor. The bottom of the support wheel is flush with the guide bar. The pressing wheel is installed above the support wheel and connected to a rotary motor. The rotary motor is installed inside the mounting component. A push rod motor is vertically connected to the top of the mounting component. The outer ring of the support wheel is also provided with a feeding mechanism for feeding the filter material after the steel ring is fitted.

[0005] The working principle of this utility model is as follows: The cut filter material is introduced through the guide bar and conveyed to the gluing mechanism for single-sided gluing through the first conveyor wheel group. After the gluing is completed, it enters the pressing mechanism under the action of the second conveyor wheel group. Before the filter material enters the pressing mechanism, the steel ring to be fitted is fitted onto the support wheel. Then, the first push rod motor controls the pressure wheel to cooperate with the support wheel to press the filter material and the steel ring together. Under the drive of the first and second rotary motors, they rotate and fit together. After the steel ring rotates several times and is fitted together, the finished steel ring is unloaded through the unloading mechanism.

[0006] The feeding mechanism includes a U-shaped component, a mounting block, and a second push rod motor. The second push rod motor is horizontally mounted below the first rotary motor. The rod of the push rod motor is equipped with a mounting block, and the U-shaped component is mounted on the mounting block.

[0007] With the above structure, the U-shaped component is pushed out by the push rod motor. Since the steel ring is larger than the support wheel, the U-shaped component can contact the hanging part below the steel ring to push it out.

[0008] A bellows is installed above the glue box.

[0009] Using the above structure, the evaporated glue is recovered through a bellows.

[0010] The U-shaped component is mounted on the mounting block using fixing bolts.

[0011] The above structure facilitates disassembly and replacement.

[0012] A stirrer is installed inside the glue tank.

[0013] With the above structure, the fluidity of the glue in the glue tank is ensured by low-speed stirring with a stirrer.

[0014] Compared with the prior art, the steel ring sleeve device of this filter bag sewing production line has the following advantages: This utility model, by setting up a continuous wheel group structure, can well complete the sleeve process from applying glue to the filter material to pasting the filter material onto the surface of the steel ring.

Detailed Implementation

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figure 1-3As shown, in the steel ring feeding device of this filter bag sewing production line, a guide bar 2 is fixedly installed in the middle of the frame 1 as the feeding end. A first set of conveyor wheels 3 is installed above the guide bar 2. A second set of conveyor wheels 4 is installed horizontally behind the first set of conveyor wheels 3. A glue applicator is installed between the second set of conveyor wheels 4 and the first set of conveyor wheels 3. The glue applicator includes a rubber wheel 5 and a glue box 6. The glue box 6 is installed below the second set of conveyor wheels 4 and the first set of conveyor wheels 3. The rubber wheel 5 is installed inside the glue box 6, and the top of the rubber wheel 5 is slightly higher than the height of the guide bar 2. A pressing mechanism for pressing the filter material and the steel ring is installed behind the second conveyor wheel assembly 4. The pressing mechanism includes a support wheel 7 and a pressure wheel 8. The support wheel 7 is installed behind the second conveyor wheel assembly 4 and connected to a rotary motor 9. The bottom of the support wheel 7 is flush with the guide bar 2. The pressure wheel 8 is installed above the support wheel 7 and connected to a rotary motor 10. The rotary motor 10 is installed inside the mounting component 11. A push rod motor 12 is vertically connected to the top of the mounting component 11. The outer ring of the support wheel 7 is also provided with a feeding mechanism for unloading the filter material after the steel ring is fitted.

[0021] In this invention, the surface of the guide strip 2 needs to be polished to reduce friction on the filter material.

[0022] In this utility model, both the first conveyor wheel assembly 3 and the second conveyor wheel assembly 4 are composed of a front conveyor wheel A and a rear conveyor wheel B. The conveyor wheel A is mainly responsible for guiding, while the conveyor wheel B is responsible for pressing and positioning. Therefore, in a specific embodiment, the surface of the conveyor wheel A is provided with protruding guiding textures to increase friction, while the surface of the conveyor wheel B is smooth and has a larger width.

[0023] In this utility model, both the first conveyor wheel assembly 3 and the second conveyor wheel assembly 4 are independently connected to corresponding electronically controlled drive structures.

[0024] In this invention, the size of the support wheel 7 is much smaller than the size of the steel ring to be processed. Therefore, when the steel ring is fitted onto the support wheel 7, it is in a swingable state, which facilitates the ejection of the unloading mechanism.

[0025] The feeding mechanism includes a U-shaped part 13, a mounting block 14, and a push rod motor 15. The push rod motor 15 is horizontally mounted below the rotary motor 9. The rod of the push rod motor is mounted with the mounting block 14, and the U-shaped part 13 is mounted on the mounting block 14.

[0026] In practice, to reduce the contact between the U-shaped part 13 and the steel ring, a plastic protective pad can be installed on the surface of the U-shaped part 13.

[0027] A bellows 16 is installed above the plastic box 6.

[0028] The air box 16 in this utility model adopts an existing air suction device product.

[0029] U-shaped part 13 is mounted on mounting block 14 by fixing bolt 17.

[0030] A stirrer 18 is installed inside the glue tank 6.

[0031] The stirrer 18 in this invention is an existing product.

[0032] The working principle of this utility model is as follows: The cut filter material is introduced through the guide bar 2 and conveyed to the gluing mechanism by the first conveyor wheel group 3 for single-sided gluing. After the gluing is completed, it enters the pressing mechanism under the action of the second conveyor wheel group 4. Before the filter material enters the pressing mechanism, the steel ring to be fitted is fitted on the support wheel 7. Then, the push rod motor 12 controls the pressure wheel 8 to cooperate with the support wheel 7 to press the filter material and the steel ring together. Under the drive of the first rotary motor 9 and the second rotary motor 10, they rotate and fit together. After the steel ring rotates several times and is fitted together, the finished steel ring is unloaded by the unloading mechanism.

[0033] In this invention, the various mechanisms are connected and driven using existing technologies, and synchronous control is achieved through a control panel.

[0034] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0035] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
