Description

Technical Field

[0001] The present invention belongs to the technical field of dust collector filter bag production equipment, and particularly relates to a dust collector filter bag body forming machine. Background Art

[0002] As is well known, a finished dust collector filter bag is in a cylindrical structure. Its formation is achieved by rolling the filter cloth into a cylindrical shape, and the two side edges of the filter cloth are in an overlapping state. Then, the overlapping two side edges are compounded together by heat sealing, thereby forming the cylindrical structure of the dust collector filter bag.

[0003] Since one side of the filter cloth has a polymer film, it will affect the hot melt adhesion of the two overlapping side edges of the filter cloth. It is necessary to process the edge part (i.e., the overlapping area) of the side of the filter cloth with the polymer film. The current processing method is: manually using a brush for processing; after the processing is completed, manually perform the overlapping and compounding work on the filter cloth. There are the following defects in using this method:

[0004] 1. Manual work has low work efficiency;

[0005] 2. Processing the surface of the filter cloth with a brush has poor processing consistency and affects hot melt adhesion;

[0006] 3. It cannot be completed online during the production process of forming the cylindrical structure, seriously affecting the production efficiency and rhythm of the cylindrical structure;

[0007] 4. The labor intensity of the staff is large;

[0008] 5. Since the overlapping part after the filter cloth is folded manually is a three-layer structure, there is a situation where all three layers are heat-sealed together when heat-sealing the overlapping part, affecting the forming quality of the product. Summary of the Invention

[0009] The present invention provides a dust collector filter bag body forming machine to achieve the purpose of mechanized online consistent processing of the edges of the filter cloth, as well as cylindrical forming and compounding, and to achieve the effects of reducing labor intensity and improving work efficiency.

[0010] To solve the above technical problems, the technical solution of the present invention is: a forming machine for the bag body of a dust collector filter bag, which includes a frame. At the starting end of the frame, there is a swinging material roll support mechanism. On the frame downstream of the swinging material roll support mechanism, there is a feeding and edge grinding mechanism. On the frame downstream of the feeding and edge grinding mechanism, there is a filter cloth flattening and holding roller; on the frame downstream of the filter cloth flattening and holding roller, there is a filter cloth arc bending and forming die.

[0016] There are multiple forming grooves on the disc body, and the multiple forming grooves are in a nested relationship and are concentrically arranged.

A superposition forming block is provided on the connecting rod. Two grooves for horizontally guiding the two side edges of the filter cloth respectively are provided on the superposition forming block. The two grooves are horizontally arranged and vertically arranged. The open ends of the two grooves are arranged in opposite directions, and the two vertically arranged grooves have an overlapping part. The support plate is arranged below the two superposition forming blocks, and both ends of the support plate extend towards the filter cloth arc bending forming die and the thermoplastic composite mechanism respectively.

[0018] As a further improvement, the thermoplastic composite mechanism includes a second linear driving element arranged on the frame. A wheel frame is provided at the driving end of the second linear driving element. A roller is rotatably installed on the wheel frame, and the roller abuts against the support plate.

[0019] An air supply pipe is provided on the frame upstream of the roller. An air inlet pipe is communicated with the air supply pipe, and an electric heating element is provided in the air supply pipe. The air outlet end of the air supply pipe is bent towards the superposition forming block and is located between the two grooves.

[0020] As a further improvement, a protective plate is provided on one side of the superposition forming block close to the roller. Filter cloth restraint grooves and isolation grooves arranged vertically are provided on the protective plate. The filter cloth restraint groove is communicated with the groove above the superposition forming block, and the isolation groove is higher than the groove below the superposition forming block. The air outlet end of the air supply pipe is bent into the isolation groove.

[0021] A protective cover is provided on the frame on one side of the air supply pipe.

[0022] As an improvement, a filter cloth side edge guiding mechanism is provided upstream of the filter cloth side edge pre - superposition into cylinder mechanism, and a filter cloth side edge guiding and gathering mechanism is provided upstream of the filter cloth side edge superposition into cylinder mechanism. A traction pressing mechanism is provided on the frame downstream of the thermoplastic composite mechanism.

[0023] As a further improvement, both the filter cloth side edge guiding mechanism and the filter cloth side edge guiding and gathering mechanism include L - shaped pads arranged on the support plate. A guiding channel for pre - guiding one side edge of the filter cloth is formed between the pads and the support plate. A pressing wheel for pressing the other side edge of the filter cloth is rotatably installed on the frame above the pads. A plurality of inclined guiding ridges are provided on the upper surface of the pads.

[0024] On the frame on one side of the cushion block on the side guide and gathering mechanism of the filter cloth, a guide feed pressure wheel is also rotatably installed. The guide feed pressure wheel abuts against the support plate. The feed pressure wheel and the guide feed pressure wheel are both inclined and arranged in a "V" shape, and the end with a smaller distance between the feed pressure wheel and the guide feed pressure wheel is close to the filter cloth side stacking into a cylinder mechanism;

[0025] The traction and pressing mechanism includes two roller shafts rotatably installed on the frame, and one of the roller shafts is driven by a power source.

[0026] After adopting the above technical solution, the effects of the present invention are as follows:

[0027] Since the dust collector filter bag body forming machine includes a frame, a swing type material roll support mechanism is provided at the starting end of the frame, a guide and edge grinding mechanism is provided on the frame downstream of the swing type material roll support mechanism, and a filter cloth flattening and holding roller is provided on the frame downstream of the guide and edge grinding mechanism; a filter cloth arc bending and forming die is provided on the frame downstream of the filter cloth flattening and holding roller, a filter cloth side pre-stacking into a cylinder mechanism is provided on the frame downstream of the filter cloth arc bending and forming die, a filter cloth side stacking into a cylinder mechanism is provided on the frame downstream of the filter cloth side pre-stacking into a cylinder mechanism, a support plate is provided between the filter cloth side stacking into a cylinder mechanism and the filter cloth side pre-stacking into a cylinder mechanism, and a thermoplastic composite mechanism is provided on the frame downstream of the filter cloth side stacking into a cylinder mechanism. Based on the above structure, during the use of the dust collector filter bag body forming machine, the material roll is supported by the swing type material roll support mechanism, and then, the filter cloth on the material roll is tractionally conveyed by the traction and conveying mechanism downstream of the dust collector filter bag body forming machine. During the conveying process, the filter cloth is synchronously guided and edge ground by the guide and edge grinding mechanism, and the filter cloth flattening and holding roller ensures that the filter cloth is in a horizontal unfolded state when edge grinding the filter cloth (because the downstream of the guide and edge grinding mechanism is a device for winding the filter cloth into a cylindrical shape, and the filter cloth in a horizontal unfolded state can effectively edge grind the filter cloth); the filter cloth is arc bent by the filter cloth arc bending and forming die, and through the cooperation of the filter cloth side pre-stacking into a cylinder mechanism and the filter cloth side stacking into a cylinder mechanism, the upper and lower layers of the two sides of the arc bent filter cloth are stacked, and the thermoplastic composite mechanism composites the stacked two sides of the filter cloth together, thereby completing the forming of the cylindrical filter bag.

[0028] In summary, by using the dust collector filter bag body forming machine, the purpose of mechanized online edge grinding consistency treatment of the filter cloth, as well as cylindrical forming and composite is achieved. At the same time, the labor intensity of the staff is greatly reduced, the work efficiency is effectively improved, and the production rhythm, production continuity and product quality are ensured.

[0029] Since the feeding and edge grinding mechanism includes two baffles arranged on the frame, an avoidance groove is provided on one of the baffles, a grinding wheel driven by a power device is rotatably installed in the avoidance groove, the width of the grinding wheel is greater than the width of the baffle, and a pressing wheel is rotatably installed on the frame above the grinding wheel. Thus, the filter cloth is fed by the two baffles. At the same time, the baffle can also play a role in safety protection. When the filter cloth passes between the grinding wheel and the pressing wheel, the edge of the filter cloth is ground by the grinding wheel. The structure is simple and the edge grinding consistency effect is good.

[0030] Since support rollers are provided on the frame on both sides of the grinding wheel, the baffle is slidably adjusted and installed on the support rollers. A connecting frame is provided on one of the support rollers, and a pressing wheel is rotatably installed on the connecting frame. Thus, the filter cloth is supported by the two support rollers, so that the filter cloth is in a flat state before and after edge grinding, ensuring that the filter cloth only contacts at the position of the grinding wheel, effectively avoiding the problem that the filter cloth sags and contacts the grinding wheel, causing damage to the filter cloth. Since the baffle is slidably adjusted and installed on the support rollers, the working position of the baffle can be adjusted according to the width of the filter cloth.

[0031] Since the power device includes a base slidably adjusted and installed on the frame, a motor is provided on the base, and the motor drives the grinding wheel. The structure is simple, it can adapt to the adjustment of the baffle, and the adjustment is convenient. The driving effect on the grinding wheel is good, meeting the conveying and edge grinding requirements of filter cloths with different widths.

[0032] A protective ring is provided on the outer periphery of the grinding wheel below the baffle, and the protective ring is arranged on the base, so as to play a safety protection role when the grinding wheel works through the protective ring.

[0033] Since the swing-type coil support mechanism includes support plates hinged to both sides of the frame, shaft grooves are provided on the support plates, a coil shaft is provided in the two shaft grooves, and coils are provided on the coil shaft. It also includes a first linear driving element with one end hinged to both sides of the frame, and the other end of the first linear driving element is hinged to the support plate. Two stoppers are fixedly installed on the coil shaft, and the two stoppers are arranged on both sides of the coil. Thus, the coil shaft (with coils thereon) is constrained through the shaft grooves. Then, the first linear driving element drives the support plate to swing to a suitable position according to the diameter of the coil. The structure is simple, facilitating the rapid loading of the coil, and having good support for the coil. At the same time, it can meet the support requirements of coils with different diameters.

[0034] Since the filter cloth arc bending forming die includes a support rod arranged on the frame, a disc body is fixedly installed on the support rod, and a forming groove is provided on the disc body. The forming groove extends in an arc with the center of the circle as the base point and with the same radius. Thus, the filter cloth can achieve arc bending work after passing through the forming groove. The structure is simple and the forming is fast.

[0035] Since a plurality of forming grooves are provided on the disc body, and the plurality of forming grooves are in a nested relationship and are concentrically arranged, different diameter arc bending work can be carried out on the filter cloth as required.

[0036] Since both the filter cloth side superposition into cylinder mechanism and the filter cloth side pre - superposition into cylinder mechanism include a connecting rod vertically adjusted and installed on the frame, the connecting rod is provided with a superposition forming block, and the superposition forming block is provided with two grooves for horizontally guiding the two sides of the filter cloth respectively. The two grooves are horizontally arranged and vertically arranged, the open ends of the two grooves are arranged back to back, and the two vertically arranged grooves have an overlapping part; the support plate is arranged below the two superposition forming blocks, and both ends of the support plate extend towards the filter cloth arc bending forming die and the thermoplastic composite mechanism respectively, so as to complete the superposition of the two sides of the filter cloth through the guidance of the two grooves arranged back to back (the surface - treated filter cloth side passes through the lower groove). The structure is simple and the superposition forming effect is good.

[0037] Since the thermoplastic composite mechanism includes a second linear driving element arranged on the frame, the driving end of the second linear driving element is provided with a wheel frame, a roller is rotatably installed on the wheel frame, and the roller abuts against the support plate; an air supply pipe is arranged on the frame upstream of the roller, an air inlet pipe is communicated with the air supply pipe, and an electric heating element is arranged in the air supply pipe; the air outlet end of the air supply pipe is bent towards the superposition forming block and is located between the two grooves. Thus, during compounding, the air inlet pipe continuously conveys gas to the air supply pipe, the electric heating element heats the gas in the air supply pipe, and then it is conveyed between the two sides of the superposed filter cloth. Thus, through the cooperation of the roller and the support plate, the heated two sides of the filter cloth are roll - pressed and compounded. The structure is simple, the pressure is stable, and the continuous pressing effect is good.

[0038] Since a protection plate is arranged on one side of the superposition forming block close to the roller, the protection plate is provided with a filter cloth restraint groove and an isolation groove arranged vertically. The filter cloth restraint groove is communicated with the groove above the superposition forming block, the isolation groove is higher than the groove below the superposition forming block, and the air outlet end of the air supply pipe is bent into the isolation groove. Thus, the protection plate is used to isolate the filter cloth and the air supply pipe, which not only does not affect the normal conveyance of the filter cloth, but also can prevent the filter cloth from being damaged due to direct contact with the air supply pipe.

[0039] Since a protective cover is arranged on the frame on one side of the air supply pipe, the protective cover is used to protect the air supply pipe, playing a role in protecting the safety of the staff.

[0040] Since a filter cloth side guiding mechanism is arranged upstream of the filter cloth side pre - superposition into cylinder mechanism, and a filter cloth side guiding and gathering mechanism is arranged upstream of the filter cloth side superposition into cylinder mechanism; a traction and pressing mechanism is arranged on the frame downstream of the thermoplastic composite mechanism. Thus, the two sides of the filter cloth are guided by the filter cloth side guiding mechanism and the filter cloth side guiding and gathering mechanism, which is beneficial to the superposition effect of the two sides of the filter cloth; the compounded cylindrical structure is flattened and tractioned by the traction and pressing mechanism, which is beneficial to subsequent centralized collection.

[0041] Since both the filter cloth side guiding mechanism and the filter cloth side guiding and gathering mechanism include L-shaped cushion blocks arranged on the supporting plate, a guiding channel for pre-guiding the side of one of the filter cloths is formed between the cushion block and the supporting plate; a pressing wheel for pressing and guiding the other side of the filter cloth is rotatably installed on the frame above the cushion block; a guiding and pressing wheel is also rotatably installed on the frame on one side of the cushion block of the filter cloth side guiding and gathering mechanism, and the guiding and pressing wheel abuts against the supporting plate. Both the pressing wheel and the guiding and pressing wheel are inclined and arranged in a "V" shape, and the end with a smaller distance between the pressing wheel and the guiding and pressing wheel is close to the filter cloth side superposition cylinder mechanism. Thus, the sides of the filter cloth are respectively subjected to roller pressing and guiding by the pressing wheel and the guiding and pressing wheel, and the filter cloth is guided through the guiding channel, which can not only make the two sides approach each other, but also lay a foundation for the two sides of the filter cloth to be quickly superposed on the filter cloth side superposition cylinder mechanism.

[0042] Since a plurality of inclined guiding ridges are provided on the upper surface of the cushion block, the side of the filter cloth being pressed can be guided towards the other side through the guiding ridges, which is beneficial to the superposition of the two sides of the filter cloth.

[0043] Since the traction and pressing mechanism includes two roller shafts rotatably installed on the frame, and one of the roller shafts is driven by a power source, the flattening and traction are realized through the two roller shafts, and the structure is simple, and the flattening and traction effects are good.

[0058] As Figure 2 and Figure 3 As shown together, the feeding and edge grinding mechanism 3 includes two baffle plates 301 arranged on the frame 1. On one of the baffle plates 301, there is an avoidance groove 302. Inside the avoidance groove 302, a grinding wheel 303 driven by a power device is rotatably installed.
