Description

Technical Field

[0001] The invention belongs to the technical field of dust collector filter bag production equipment, and in particular relates to a cylindrical bag body forming device for dust collector filter bag production. Background Art

[0002] As we all know, the finished dust collector filter bag is a cylindrical structure, which is formed by folding the filter cloth and overlapping the two sides of the filter cloth, and then compounding the two overlapping sides together by heat sealing, thereby forming a dust collector filter bag that is cylindrical when used.

[0003] The above-mentioned superposition of filter cloths is all done manually, and this method has the following defects:

[0004] 1. The labor intensity of the staff is high;

[0005] 2. Low work efficiency;

[0006] 3. Since the overlapping part of the folded filter cloth is a three-layer structure, when the overlapping part is heat-sealed and compounded, the three layers are heat-sealed together, affecting product quality. Summary of the invention

[0007] The invention provides a cylindrical bag forming device for producing dust collector filter bags, so as to realize mechanized cylindrical forming of filter cloth and achieve the purpose of reducing labor intensity, improving work efficiency and ensuring product quality.

[0008] In order to solve the above technical problems, the technical solution of the present invention is: a cylindrical bag forming device for producing dust collector filter bags, comprising a frame, one end of the frame is provided with a filter cloth arc-shaped bending forming mold, and the frame located downstream of the filter cloth arc-shaped bending forming mold is provided with a filter cloth side stacking tube mechanism, the filter cloth side stacking tube mechanism extends in the direction of the filter cloth arc-shaped bending forming mold, and a filter cloth side guide mechanism is provided on the extended end of the filter cloth side stacking tube mechanism.

[0009] As an improvement, the filter cloth arc bending forming die includes a support rod arranged on the frame, a disc is fixedly mounted on the support rod, a forming groove is provided on the disc, and the forming groove takes the center of the circle as a base point and extends in an arc with the same radius.

[0010] As a further improvement, the disc body is provided with a plurality of the forming grooves, and the plurality of the forming grooves are in a nested relationship and are concentrically arranged.

[0011] As a further improvement, the filter cloth side stacking tube mechanism includes a stacking forming block vertically adjusted and installed on the frame, and the stacking forming block is provided with two grooves for respectively guiding the two side edges of the filter cloth, the two grooves are horizontally arranged and arranged up and down, the open ends of the two grooves are arranged back to back, and the two grooves arranged up and down have overlapping parts.

[0012] As a further improvement, a pad is provided at the bottom of the stacked forming block, and the pad extends toward the arc-shaped bending forming die of the filter cloth.

[0013] As a further improvement, the filter cloth side guide mechanism includes an L-shaped pad block arranged on the pad plate, and a guide channel for pre-guiding one of the side edges of the filter cloth is formed between the pad block and the pad plate; a pressing wheel for pressing the other side edge of the filter cloth is rotatably installed on the frame located above the pad block.

[0014] As a further improvement, a plurality of inclined guide ridges are provided on the upper surface of the cushion block.

[0015] After adopting the above technical solution, the effects of the present invention are:

[0016] Since the cylindrical bag forming device for producing dust collector filter bags includes a frame, a filter cloth arc-shaped bending forming mold is provided at one end of the frame, a filter cloth side stacking tube mechanism is provided on the frame downstream of the filter cloth arc-shaped bending forming mold, the filter cloth side stacking tube mechanism extends in the direction of the filter cloth arc-shaped bending forming mold, and a filter cloth side guide mechanism is provided on the extended end of the filter cloth side stacking tube mechanism. Based on the above structure, when the cylindrical bag forming device for producing dust collector filter bags is in use, the straight filter cloth is bent into an arc by the filter cloth arc-shaped bending forming mold, the two side edges of the filter cloth are guided and brought closer to each other by the filter cloth side guide mechanism, and the two side edges of the filter cloth are superimposed on each other by the filter cloth side stacking tube mechanism. At this time, the cylindrical structure of the dust collector filter bag is formed.

[0017] In summary, the use of the cylindrical bag forming device for the production of dust collector filter bags realizes the mechanized cylindrical forming of the flat filter cloth, which not only greatly reduces the labor intensity of the staff, but also greatly improves the work efficiency; at the same time, in the subsequent heat sealing and compounding work, only the overlapping parts on both sides of the filter cloth are compounded, which effectively ensures the product quality.

[0018] Since the filter cloth arc bending forming die includes a support rod arranged on a frame, a disc body is fixedly mounted on the support rod, and a forming groove is provided on the disc body. The forming groove takes the center of a circle as a base point and extends in an arc with the same radius, the filter cloth can be bent in an arc by passing through the forming groove. The structure is simple and the forming is fast.

[0019] Since the disc body is provided with a plurality of forming grooves, the plurality of forming grooves are in a nested relationship and are concentrically arranged, so that the filter cloth can be bent into arcs with different diameters as required.

[0020] Since the filter cloth side stacking and forming tube mechanism includes a stacking and forming block vertically adjusted and installed on the frame, the stacking and forming block is provided with two grooves for respectively guiding the two side edges of the filter cloth, the two grooves are horizontally arranged and arranged up and down, the opening ends of the two grooves are arranged back to back, and the two grooves arranged up and down have overlapping parts, so that the stacking of the two side edges of the filter cloth is completed by guiding the two grooves arranged back to back, the structure is simple, and the stacking and forming effect is good.

[0021] Since a pad is provided at the bottom of the stacked forming block, the pad extends toward the arc-shaped bending forming die of the filter cloth, so that the cylindrical filter cloth being conveyed can be supported by the pad, and at the same time, a guarantee is provided for setting a side guide mechanism for the filter cloth.

[0022] Since the filter cloth side guide mechanism includes an L-shaped pad arranged on the pad, a guiding channel for pre-guiding one of the side edges of the filter cloth is formed between the pad and the pad; a pressing wheel for pressing the other side edge of the filter cloth is rotatably installed on the frame located above the pad, so that one side edge of the filter cloth is roller-guided by the pressing wheel, and the other side edge of the filter cloth is guided by the guiding channel, which not only makes the two side edges approach each other, but also lays a foundation for the two side edges of the filter cloth to be quickly stacked on the filter cloth side stacking tube mechanism.

[0023] Since a plurality of inclined guide ridges are arranged on the upper surface of the pad block, the side edge of the filter cloth being pressed can be guided toward the other side edge through the guide ridges, which is beneficial to the superposition of the two side edges of the filter cloth.
