Description

Technical Field

[0001] This utility model relates to the field of filter bag manufacturing, and in particular to a filter bag support frame forming device. Background Technology

[0002] Filter bags are a common type of air filter element. Due to their large windward surface, large dust volume, and low air velocity, they are considered to be the best medium-efficiency filters currently available.

[0003] like Figure 1 As shown, a schematic diagram of a common bag filter is provided, including an outer frame 9 and a filter bag 10 fixedly connected to the outer frame 9. The outer frame 9 is usually rectangular and includes a first side 11, two second sides 12 respectively fixed to the two ends of the first side 11 and arranged perpendicular to the first side 11, and a third side 13 fixed to the two second sides 12 at both ends.

[0004] The outer frame is usually set as a rectangular frame for easy installation. The rectangular frame is usually made by bending a strip of raw material of a fixed length and then fixing it at both ends. Currently, the assembly line processing involves manually bending and shaping the material at a specific station and then transferring it to a subsequent station for fixing. This process involves many steps and is time-consuming. Utility Model Content

[0005] The purpose of this invention is to provide a filter bag support frame forming device, which has the advantage of being able to integrally form the filter bag support frame, thereby simplifying the processing steps and improving production efficiency.

[0006] To achieve the above and other related objectives, this utility model provides the following technical solution: a filter bag support frame forming device, comprising:

[0007] The first support member supports the middle part of the strip-shaped material to prevent it from deforming, and the length of the support part is equal to the length of the first side.

[0008] The first bending assembly bends the strip-shaped raw materials located on both sides of the first support member toward the same side;

[0009] The second support member is disposed between the two strips of raw material that are bent by the first bending component, and the width of the second support member is equal to the length of the third side.

[0010] The second bending assembly applies a compressive force to both ends of the strip material, causing it to tilt and bend around the second support member; and,

[0011] The locking assembly locks and fixes the joined ends of the strip-shaped raw material.

[0012] Through the above technical solution, the middle part of the strip-shaped raw material is supported by the first support member. Then, the first bending assembly bends the strip-shaped raw material located on both sides of the first support member toward the same side to bend out the first side. After bending, the two sides of the strip-shaped raw material are located on both sides of the second support member. Then, the second bending assembly squeezes the two ends of the strip-shaped raw material respectively, and bends out two second sides and a third side. At this time, the third side is in an open state. Then, the locking assembly locks and fixes the spliced ​​parts at both ends of the strip-shaped raw material to form a complete third side, thereby completing the forming process of the frame. This solution integrally forms the outer frame of the bag filter, eliminating the need for processing at multiple workstations, thus simplifying the processing steps and improving production efficiency.

[0013] In one embodiment of the present invention, the first bending assembly includes:

[0014] A pair of extruders; and a pull-out drive that drives the first support to slide, causing the first support to carry the strip material through the pair of extruders, so that the extruders apply an extrusion force to the strip material to deform it.

[0015] With the above technical solution, after the strip material is installed on the first support member, the pull-out drive member drives the first support member to pass through the paired extrusion members. During the passage, the strip material will bend due to the extrusion of the extrusion members, thus bending out the first side.

[0016] In one embodiment of the present invention, the second bending assembly includes:

[0017] A bending drive; and a bending clamping block driven to slide by the bending drive, wherein the strip material is disposed in the sliding path of the bending clamping block, and the sliding direction of the bending clamping block is inclined to the length direction of the strip material so as to apply a bending force to the strip material during sliding, wherein the bending drive and the bending clamping block are provided in two sets, respectively corresponding to one end of the strip material.

[0018] With the above technical solution, after the strip material is bent by the first bending component, both sides of the strip material will reach both sides of the second support. At this time, the strip material is located on the sliding path of the bending clamping block. Then the bending drive component drives the bending clamping block to slide. During the sliding process, the bending clamping block will squeeze the strip material to make the strip material bend, thereby bending out the second side and the unclosed third side.

[0019] In one embodiment of the present invention, the second support member includes block a and block b, which are spaced apart and respectively attached to a portion of the bent strip material.

[0020] Through the above technical solution, blocks a and b are used to restrict the strip-shaped material on one side, causing the strip-shaped material to bend under pressure.

[0021] In one embodiment of the present invention, the locking assembly includes:

[0022] A pressure block is provided between block a and block b; a stamping block is provided opposite to the pressure block; and a stamping drive is provided to drive the stamping block to apply pressure to the strip-shaped material, so that the stamping block and the pressure block cooperate to stamp out a buckle that engages the two ends of the strip-shaped material on the strip-shaped material.

[0023] With the above technical solution, after the strip material is bent by the second bending component, the two ends of the strip material will be attached between block a and block b. Then, the stamping drive component drives the stamping block to move in the direction of the strip material. The stamping drive component and the pressure block cooperate to stamp out a buckle at the overlapping part of the strip material. The buckle locks and fixes the two ends of the strip material.

[0024] In one embodiment of this utility model, the extrusion member is configured as an extrusion roller.

[0025] With the above technical solution, when the strip-shaped raw material passes between two extrusion rollers and is squeezed by the extrusion rollers, the extrusion rollers will rotate, reducing the friction between the extrusion rollers and the strip-shaped raw material, thereby preventing the strip-shaped raw material from wearing out.

[0026] In one embodiment of the present invention, the first support member is provided with a support groove for inserting the middle part of the strip-shaped raw material, and the length of the support groove is equal to the length of the first side.

[0027] Through the above technical solution, the length of the support groove that prevents the strip-shaped material from deforming is the length of the first side.

[0028] As described above, the filter bag support frame forming device of this utility model has the following beneficial effects:

[0029] The middle part of the strip-shaped raw material is supported by the first support member. Then, the first bending assembly bends the strip-shaped raw material on both sides of the first support member toward the same side to bend out the first side. After bending, the two sides of the strip-shaped raw material are respectively located on both sides of the second support member. Then, the second bending assembly squeezes the two ends of the strip-shaped raw material and bends out two second sides and a third side. At this time, the third side is not closed. Then, the locking assembly locks and fixes the spliced ​​parts at both ends of the strip-shaped raw material to form a complete third side, thereby completing the forming process of the frame. This solution integrally forms the outer frame of the bag filter, eliminating the need for processing at multiple workstations, thus simplifying the processing steps and improving production efficiency.
