Description

Technical Field

[0001] The invention relates to the field of filter bag processing equipment, in particular to a filter bag production sewing device with a continuous conveying mechanism. Background Art

[0002] Dust filter bags are a type of equipment used for air purification in industrial production. Their main function is to filter dust and particulate matter in the air. They are usually made of special fiber materials that are resistant to high temperatures, corrosion, and wear. They are widely used in various industrial sites, such as cement plants, steel plants, power plants, chemical plants, etc.

[0003] The fabric of the dust filter bag must be triple-sewn at the bag body, bag opening and bag bottom to form a complete dust filter bag. The bag body and bag opening, bag body and bag bottom are sewn separately. The bag body and bag head are sewn by putting the bag body into the bag head prepared in advance and sewing it on a sewing machine by manual rotation.

[0004] To this end, a Chinese patent provides a high-efficiency sewing device for the production of dust filter bags (publication number: CN114507949A), which sews the bag body, bag tail and bag head together to improve the production efficiency of the entire dust bag, and then fixes the entire bag tail through an arc-shaped tooth plate and a semicircular ring, while driving the entire bag tail to rotate and sew, so as to solve the problem that the material of the bag body and the bag bottom is relatively soft, which is easy to cause the bottom of the dust filter bag to be damaged during operation after sewing.

[0005] However, in the actual production and processing of dust filter bags, it is often necessary to place tie strips in the bag head first and then sew them. The above patent content lacks the required tie strip placement structure, so the operator needs to manually place the tie strips and then sew the bag head, which greatly affects the continuity of work and makes it difficult to achieve automatic and continuous installation of the tie strips.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figure 1 - Figure 5 As shown, this embodiment is a suturing device for filter bag production with a continuous conveying mechanism, including a fixed frame, a conveyor belt is fixedly installed on the fixed frame, a movable frame is movably installed on the fixed frame, the movable frame is located on one side of the conveyor belt, a storage box is arranged above the movable frame, and the storage box is fixedly connected to the fixed frame.

[0031] A conveying assembly 2 is movably installed in the fixed frame 1, and the conveying assembly 2 includes a rotating frame 201, a fixed plate 202 and a movable plate 203. The rotating frame 201 is movably installed in the movable frame 102, the fixed plate 202 is fixedly installed on the rotating frame 201, and the movable plate 203 is movably installed on one side of the fixed plate 202.

[0032] The conveying component 2 also includes a support rod 204, an airbag 1 205, an airbag 206 and a moving rod 1 207. The support rod 204 is movably installed on the side of the conveyor belt 101 away from the moving frame 102, the airbag 1 205 is fixedly installed in the moving frame 102, the airbag 2 206 is fixedly connected to the moving rod 1 207, and the end of the moving rod 1 207 away from the airbag 2 206 is fixedly connected to the support rod 204, and the airbag 1 205 is fixedly connected to the airbag 2 206 through a pipeline.

[0033] A cylinder 208 is fixedly installed on one side of the storage box 103, and a limit block 209 is fixedly installed on the output end of the cylinder 208. The limit block 209 is movably installed in the storage box 103. First, a plurality of tie bars are placed in the storage box 103. In the initial state, the tie bars are kept fixed under the action of the limit block 209. When the tie bars are installed, the cylinder 208 drives the limit block 209 to be retracted. At this time, the tie bars fall onto the rotating frame 201 under the action of gravity. When the bottom tie bars fall, the cylinder 208 drives the limit block 209 to reset to block the remaining tie bars above to prevent the remaining tie bars from falling.

[0034] A motor is fixedly installed on one side of the mobile frame 102, and a rotating rod 210 is fixedly installed on the output end of the motor. One end of the rotating rod 210 is fixedly connected to the rotating frame 201. An electric push rod is fixedly installed on one side of the rotating frame 201, and the output end of the electric push rod is fixedly connected to the mobile plate 203. A screw rod 211 is movably installed inside the fixed frame 1. A motor is fixedly installed on the side of the fixed frame 1 away from the conveyor belt 101, and the output end of the motor is fixedly connected to the screw rod 211. A moving nut 212 is movably installed on the screw rod 211 through a thread, and the top of the moving nut 212 is fixedly connected to the mobile frame 102.

[0035] An electric push rod is fixedly installed in the rotating frame 201, and a lifting rod 213 is fixedly installed at the output end of the electric push rod. The top of the lifting rod 213 passes through the movable frame 102, and the lifting rod 213 is located on both sides of the fixed plate 202. When the movable frame 102 drives the tie bar to enter the bag head, the electric push rod in the rotating frame 201 is started, driving the lifting rod 213 to move, and the tie bar on the fixed plate 202 is pushed by the lifting rod 213, thereby separating the tie bar from the fixed plate 202. When the tie bar is separated from the fixed plate 202, under the action of elastic force, the tie bar gradually recovers until it fits with the inner wall of the bag head, and the movable frame 102 is gradually reset.

[0036] During the process of resetting the movable frame 102, the tie bar has not yet fully recovered, and the cylinder 2 219 is started to drive the support rod 204 to reset. When the airbag 1 205 is gradually reset, the gas re-enters the airbag 1 205 from the airbag 2 206, and the airbag 206 contracts to drive the movable rod 1 207 to reset, and then drives the connecting rod to reset. At this time, the support rod 204 is moved out from the bag head, and the tie bar is fully restored to open the bag head.

[0037] Specifically, the tie strip falls from the storage box 103 to the rotating frame 201. At this time, the fixed plate 202 is located in the tie strip, pushing the movable plate 203 to squeeze one side of the tie strip, compressing the area of ​​the tie strip, driving the rotating frame 201 to rotate, and making the movable frame 102 move in the fixed frame 1. During the movement of the movable frame 102, the airbag 1 205 is squeezed, and the airbag 2 206 expands accordingly. The airbag 2 206 pushes the movable rod 1 207 to move, and then the support rod 204 is inserted into the bag head on the conveyor belt 101. As the support rod 204 moves, the bag head is propped up, and the movable frame 102 continues to move, driving the tie strip to enter the bag head, thereby realizing the fully automatic installation of the tie strip, greatly improving the sewing efficiency of the dust filter bag.

[0038] Example 2: Please refer to Figure 6 - Figure 7As shown, the present invention also includes a support rod 204, a connecting plate 217 is fixedly installed on one end of the moving rod 1 207 away from the airbag 2 206, a cross plate 218 is fixedly installed on the connecting plate 217, a cylinder 219 is fixedly installed on the cross plate 218, two cross plates 218 are provided, and the cross plates 218 are symmetrically arranged on the connecting plate 217, and support rods 204 are fixedly installed on the output ends of the cross plate 218 and the cylinder 2 219, and the two support rods 204 are symmetrically arranged.

[0039] When the bag head is placed on the conveyor belt 101, the center of the bag head sinks under the action of gravity, and the top of the bag head presents a concave state with high ends and low middle. At this time, there is a gap at both ends of the bag head, and the symmetrically arranged support rods 204 are slightly smaller than the gap. Then, the support rods 204 are pushed into the gaps at both ends of the bag head by moving rod 1 207, and then the upper support rods 204 are driven to move upward by cylinder 2 219 to support the bag head.

[0040] A fixed tube 214 is fixedly installed on the fixed frame 1, a movable rod 207 is movably installed in the fixed tube 214, an airbag 206 is fixedly installed in the fixed tube 214, a fixed tube 215 is fixedly installed on the side of the movable frame 102 close to the airbag 205, a movable rod 216 is movably installed inside the fixed tube 215, the top of the movable rod 216 is fixedly connected to the airbag 205, a spring is fixedly installed on the side of the movable rod 216 away from the airbag 205, and one end of the spring is fixedly connected to the inner wall of the fixed tube 215.

[0041] During the movement of the mobile frame 102, the fixed tube 215 is driven to move, and the mobile rod 216 is gradually squeezed with the airbag 1 205, and the airbag 1 205 gradually shrinks. When the airbag 1 205 is completely contracted, the mobile rod 216 gradually moves under the squeezing, and the spring is gradually compressed. Through the cooperation of the fixed tube 215 and the mobile rod 216, it is ensured that when the airbag 1 205 is squeezed into place, it does not affect the normal movement of the mobile frame 102. At the same time, the spring is used to assist the mobile rod 216 to reset, thereby ensuring the stability of the mobile rod 2 during movement.

[0042] After the installation of the tie strip is completed, it continues to follow the conveyor belt 101 to move to the sewing device, wherein the type of the sewing device is determined according to actual needs. When the conveyor belt 101 drives the installed bag head to move to the sewing device, the operator places the assembled bag head directly on the sewing device for sewing, and no additional manual assembly of the bag head is required, which effectively saves manpower. At the same time, the tie strip is placed in the bag head through a mechanical structure, the placement position deviation is small, and the placement effect is not affected by work experience and is more efficient, that is, the installed bag head is continuously transported to the subsequent sewing device through the conveyor belt 101 to ensure the continuity of the sewing work.

[0043] Combining Example 1 and Example 2, it can be known that the tie strip is squeezed and fixed by the fixed plate 202 and the movable plate 203, and the bag head is propped up by the support rod 204, and the tie strip is placed in the bag head, so as to realize the fully automatic installation of the tie strip, greatly improving the sewing efficiency of the dust filter bag, and at the same time, the installed bag head is continuously transported to the subsequent sewing device through the conveyor belt 101 to ensure the continuity of the sewing work.

[0044] The working process and principle of the present invention are as follows:

[0045] The tie strips are squeezed and fixed by the fixed plate 202 and the movable plate 203, and the bag head is propped up by the support rod 204, and the tie strips are put into the bag head at the same time, so as to realize the full-automatic installation of the tie strips, which greatly improves the sewing efficiency of the dust filter bag;

[0046] Furthermore, the installed bag head is continuously transported to the subsequent sewing device through the conveyor belt 101 to ensure the continuity of the sewing work;

[0047] In summary, the present invention not only realizes the automatic placement of the tie strip, but also ensures the continuity of the sewing work by continuously conveying the bag head.
