Description

Technical Field

[0001] This utility model relates to the field of filter bag manufacturing, and in particular to a device for manufacturing steel belts for filter bags. Background Technology

[0002] The support ring at the filter bag opening is a crucial component for the filter bag's integration with the dust collector. This support ring is typically made of steel strip, which is first cut to a specific length on a punch press and then riveted together. Currently, most manufacturers manually cut the steel strip used for preparing the filter bag opening support ring.

[0003] During operation, after the steel strip is cut to a certain length on the punch press, manual production requires bending, punching, and fixing the steel strip manually. This requires the operator to perform repetitive mechanical labor, which can easily lead to errors and mistakes after long periods of work. This results in poor product consistency, is time-consuming and labor-intensive, inefficient, and has high labor costs. It also poses certain risks to the operation and is not conducive to production. Utility Model Content

[0004] The purpose of this invention is to provide a device for manufacturing steel belts for filter bags, which can automatically or semi-automatically complete the manufacturing of steel belts, thereby improving manufacturing efficiency and freeing up workers' productivity.

[0005] To achieve the above objectives, the solution of this utility model is: A filter bag steel belt manufacturing apparatus includes a fixing mechanism, a rounding mechanism, a clamping mechanism, a conveying mechanism, and an automatic control system. The fixing mechanism includes an annular fixing seat, with a circular hollow part in the middle of the fixing seat, an inner annular surface on the inner side of the fixing seat, and an annular limiting groove inside the fixing seat for inserting and limiting a strip of steel. The limiting groove has a notch at the bottom of the fixing seat, and the two ends of the notch form the input end and the output end of the steel strip, respectively. The rounding mechanism includes a rotating shaft passing through the center of the hollow part of the fixed base. The rotating shaft is fixed on a support base. At least three rounding brackets extend outward from the circumference of the rotating shaft. The outer side of the rounding brackets abuts against the inner ring surface of the fixed base. The rounding brackets press the inner ring surface of the fixed base while pressing the steel strip in the limiting groove and rounding the steel strip in the limiting groove during the rotation of the rotating shaft. The clamping mechanism includes a liftable clamping seat and a screw seat. The clamping seat is arc-shaped. When the rotating shaft rotates, the clamping seat rises and fills the notch in the fixed seat. The clamping seat has a through hole for the screw to pass through. After the steel strip rotates once, the screw seat rises to the clamping seat, and the screw attracted on the screw seat passes through the through hole to fix the steel strip. The transmission mechanism includes a pusher and a transmission hook. The pusher is mounted on a fixed base and located behind the limiting groove. The limiting groove forms a through groove on the front side of the fixed base. The pusher has a push part that can be pushed forward and retracted. When the push part is pushed forward, it passes through the limiting groove, pushes the steel strip forward, pushes it out of the through groove, and it falls into the transmission hook. The tail end of the transmission hook is rotatably connected to the support base. The front end of the transmission hook forms a hook part that can receive the steel strip and is located in front of the through groove. The automatic control system controls the opening, closing, and movement of the clamping mechanism, transmission mechanism, and rotating shaft.

[0006] Furthermore, the strip steel is embedded in the limiting groove, and the inner ring surface of the fixing seat is made of rubber.

[0007] Furthermore, one side of the clamping seat is also equipped with a cutter that can cut the steel strip. The cutter cuts the steel strip after it is fixed with screws.

[0008] Furthermore, the pusher is a push rod that can be pushed forward at a time. When the push rod is pushed forward, it passes through the limiting groove and pushes the steel strip. After the push rod is pushed forward, it retracts.

[0009] Furthermore, four circular supports extend outward from the circumference of the rotating shaft, each forming a four-bar linkage mechanism. Each circular support includes a base rod fixed on the circumference of the rotating shaft, with support rods pivotally connected to both ends of the base rod. The outer ends of the two support rods are connected to a fitting piece that can abut against the inner ring surface of the fixed seat.

[0010] Furthermore, the support base is fixed on the base, and the circular support mechanism supports the fixed base. The fixed base includes two parallel and spaced annular fixed blocks. The fixed blocks are simultaneously mounted on the circular support mechanism. Each fixed block has a limiting groove. The steel strip passes through the limiting groove between the two fixed blocks. The pushing member is set on the fixed block near the support base. The front side of the limiting groove of the fixed block away from the support base forms a through groove.

[0011] Furthermore, the clamping seat is located below the two fixing blocks, each fixing block has a notch at its bottom, and the arc-shaped clamping seat fills the area below the two notches. The clamping seat has four through holes.

[0012] Furthermore, after the steel belt rotates once, a superimposed section is formed between the first and last ends of the steel belt, and the screw passes through the superimposed section and is then pressed and positioned.

[0013] Furthermore, in the limiting groove of the fixed seat, multiple balls are arranged around the inner side of the groove surface, with the balls protruding from the groove surface.

[0014] Furthermore, the automatic control system is installed on the support base, the fixed base is located in front of the support base, and a storage tray is provided behind the support base to collect the steel belt transmitted by the transmission mechanism.

[0015] With the above structure, the filter bag steel belt manufacturing device of this utility model can automatically or semi-automatically complete the steel belt manufacturing, transforming the previous manual steel belt manufacturing into automated production. While ensuring accuracy, it improves production efficiency, facilitates production, reduces human error rate when producing steel belts of different specifications, lowers production costs, and improves product quality.

[0018] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0019] Combination Figures 1 to 4 As shown, a filter bag steel belt manufacturing device includes a fixing mechanism A, a rounding mechanism B, a clamping mechanism C, a transmission mechanism D, and an automatic control system E.

[0020] The fixing mechanism A includes a ring-shaped fixing seat 1. The fixing seat 1 has a circular hollow part in the middle. The inner side of the fixing seat has an inner ring surface 11. The fixing seat 1 has an annular limiting groove 12 inside, which allows a strip of steel (not shown in the figure) to be inserted and limited. The limiting groove 12 has a notch 13 at the bottom of the fixing seat 1. The two ends of the notch 13 are respectively the input end and the output end of the steel strip.

[0021] The rounding mechanism B includes a rotating shaft 21 passing through the center of the hollow part of the fixed base 1. The rotating shaft 21 is fixed on a support base 31. At least three rounding brackets extend outward from the circumference of the rotating shaft 21. The outer side of the rounding brackets abuts against the inner ring surface 11 of the fixed base. The rounding brackets 22 press against the inner ring surface of the fixed base while pressing against the steel strip in the limiting groove 12 and rounding the steel strip in the limiting groove 12 during the rotation of the rotating shaft 21.

[0022] The clamping mechanism C includes a liftable clamping seat 41 and a screw seat 42. The clamping seat 41 is arc-shaped and can rise and fill the notch 13 of the fixed seat 1 when the rotating shaft 21 rotates. The clamping seat 41 is provided with a through hole 411 through which the screw can pass. After the steel strip rotates one revolution, the screw seat 42 rises to the clamping seat 41, and drives the screw (not shown in the figure) adsorbed on the screw seat 42 to pass through the through hole 411 and fix the steel strip. The transmission mechanism D includes a pusher 51 and a transmission hook 52. The pusher 51 is mounted on the fixed base 1 and located behind the limiting groove 12. The limiting groove 12 forms a through groove 14 on the front side of the fixed base 1, through which the steel strip can pass. The pusher 51 has a pushing part (not shown in the figure) that can be pushed forward and retracted. When the pushing part is pushed forward, it enters the limiting groove 12, pushing the steel strip forward out of the through groove 14 and into the transmission hook 52. The tail end of the transmission hook 52 is rotatably connected to the support base 31, and the front end of the transmission hook forms a hook part 521 for receiving the steel strip, located in front of the through groove 14.

[0023] The automatic control system E is used to control the opening, closing and operation of the clamping mechanism C, the transmission mechanism D, and the rotating shaft 21.

[0024] Furthermore, if the steel strip entering the fixing seat 1 is not pre-cut into segments, a cutter that can cut the steel strip can be provided on one side of the clamping seat 41 as needed. The cutter cuts the steel strip after it is fixed with screws.

[0025] For the pusher 51, it may be a push rod structure that can be pushed forward at a time. When the push rod is pushed forward, it can pass through the limiting groove 12 and push the steel strip forward. Then the push rod retracts after being pushed forward to avoid interference in the limiting groove. The push rod is pushed forward again when the next steel strip is fixed.

[0026] In this embodiment, four circular support brackets 22 extend outward from the circumference of the rotating shaft 21. Each circular support bracket 22 forms a four-bar linkage mechanism. Each circular support bracket 22 includes a base rod 221 fixed on the circumference of the rotating shaft. Support rods 222 are pivotally connected to both ends of the base rod 221. The outer ends of the two support rods 222 are connected to a fitting piece 223 that can abut against the inner ring surface 11 of the fixed seat. The fitting piece 223 presses outward and supports the fixed seat and the strip steel strip inside it into a circle. The strip steel strip is embedded in the limiting groove 12. The fixed seat 1 can be made of rubber or other materials. Since the fixed seat and its inner ring surface have a certain deformation force, the circular support mechanism can support the fixed seat and the strip steel strip inside the fixed seat into a circle during rotation.

[0027] Support base 31 is fixed on base 32. The circular support mechanism B supports fixed base 1. In this embodiment, fixed base 1 includes two parallel, spaced-apart annular fixed blocks 10. The two fixed blocks 10 are connected and simultaneously mounted on the circular support mechanism. Each fixed block 10 has a limiting groove 12, through which a steel strip passes. A pushing member 51 is located on the fixed block 10 closest to support base 31, and a through groove 14 is formed on the front side of the limiting groove 12 of the fixed block 10 furthest from support base 31. Multiple balls (not shown in the figure) can be provided around the inner circumference of the limiting groove 12 in the limiting groove 12 of fixed base 1. The balls protrude from the groove surface of the limiting groove. When the steel strip moves forward one revolution within the limiting groove 12 and becomes circular, the balls can make the movement of the steel strip 12 within the limiting groove 12 smoother.

[0028] The clamping seat 41 is located below the two fixing blocks 10. Each fixing block 10 has a notch 13 at its bottom. The arc-shaped clamping seat 41 fills the space below the two notches 13. The clamping seat 41 has four through holes 411.

[0029] After the steel strip rotates once, an overlapping section will form between the beginning and end of the steel strip. The screw on the screw seat 42 can be drilled through this overlapping section. After passing through the overlapping section, the screw can be clamped and positioned for fixation. The screw can be a punched screw. When the strip steel strip rotates once in the limiting groove 12, the time for one rotation can be calculated by the rotation speed to estimate the rising time of the screw seat 42, or this can be achieved by adding a sensor to the clamping seat 41.

[0030] The automatic control system E is installed on the support base 31, the fixed base 1 is located in front of the support base 31, and a storage tray 6 is provided behind the support base 31 to collect the steel belt transmitted by the transmission mechanism.

[0031] When the filter bag steel belt making device of this utility model is working, the ordinary steel belt enters the fixing mechanism (enters from the input end of the notch 13 and moves in a circle to the output end), and bends in the limiting groove 12. At the same time, the rotating shaft 21 in the rounding mechanism rotates, causing the rounding bracket 22 to start moving, and rounding and shaping the steel belt in the limiting groove 12. After the steel belt rotates once in the limiting groove 12, the clamping mechanism is activated, and the steel belt is punched at the overlapping point (cut off) and screwed in. Then the fixed round steel belt is pushed out and falls onto the hook part 521. The transmission hook 52 rotates in the horizontal plane and puts the made steel belt into the storage tray, completing the making of one round steel belt.

[0032] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
