Description

Technical Field

[0001] This utility model relates to the field of filter bag technology, specifically a filter bag sewing and conveying device. Background Technology

[0002] Filter bags possess excellent chemical stability and heat resistance, representing the highest performance in the filter media industry and the most advanced type of commonly used filter materials. They achieve high levels in filtration efficiency and precision. During the production of filter bags, the fabric used for sewing the filter bags needs to be fed to the sewing machine station for sewing.

[0003] In existing technologies, when conveying the fabric used to sew filter bags, manual assistance is required to bend the conveyed fabric into a cylindrical shape, align and overlap the two ends of the fabric, and sew them together. This process is not only time-consuming and labor-intensive, affecting sewing efficiency, but also prone to sewing misalignment due to varying levels of skill among manual operators. This can affect the bag's sealing performance, and in high-temperature flue gas filtration scenarios, misaligned sewing can lead to dust leakage and shorten the bag's lifespan. Utility Model Content

[0004] The purpose of this invention is to provide a filter bag sewing and conveying device to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A filter bag sewing conveying device is used to convey the fabric to be sewn, including a base, a winding shaft rotatably connected to one end of the base, an mounting frame, a circular plate and two side plates fixedly mounted on the upper surface of the base, an electric conveyor belt installed between the two side plates, a control panel installed on the outer wall of the side plates, a plurality of through slots opened on the outer wall of the circular plate, and an auxiliary mechanism provided on the upper surface of the base and located between the mounting frame and the circular plate.

[0007] The auxiliary mechanism includes two frames, each with a slider slidably connected inside. Each slider has an electric telescopic rod II installed at one end, and a central chamber is fixedly installed at the output end of each of the two electric telescopic rod IIs. Several suction heads are installed on the bottom surface of each of the two central chambers.

[0008] Preferably, a connecting pipe is fixedly connected to the upper surface of both centralized compartments, and two movable plates are slidably connected inside the slider, with fixed rods fixedly connected to the outer walls of both movable plates.

[0009] Preferably, the frame has several insertion holes on both inner sidewalls, and the insertion holes are evenly distributed, with one end of the fixed insertion rod fitting into the insertion hole.

[0010] Preferably, a spring sheet is installed between the outer walls of the two movable plates, and one end of the fixed insertion rod passes through the connecting pipe and is movably installed inside the insertion hole.

[0011] Preferably, a guide roller one is rotatably connected inside the mounting frame, and vertical grooves are opened through both outer side walls of the mounting frame. A guide roller two is arranged between the two vertical grooves and above the guide roller one.

[0012] Preferably, both ends of the second guide roller are connected to mounting plates via shafts, and a first motor is mounted on the outer wall of the mounting plate, with the output end of the first motor connected to the second guide roller;

[0013] A second motor is installed on the outer wall of the mounting frame. The output end of the second motor is connected to one end of the guide roller. An electric telescopic rod is installed at the top of the mounting frame near both sides, and the output ends of the two electric telescopic rods are respectively fixedly connected to the mounting plate.

[0014] Preferably, a control panel is installed on the outer wall of the side panel. The output end of the control panel is electrically connected to motor one, motor two, electric telescopic rod one, electric telescopic rod two, and the input end of the electric conveyor belt. Control buttons and a display screen are installed on the outer wall of the control panel. A support plate is fixedly installed between the two outer walls of the side panels and inside the electric conveyor belt.

[0015] The beneficial effects of this utility model are:

[0016] 1. In this utility model, by setting a circular plate with a slot, the fabric passes through the slot, which automatically folds the fabric into a cylindrical shape. The connecting pipe is connected to an external vacuum pump, causing the suction head to generate suction and adsorb the fabric. Combined with two centralized chambers with a height difference and two electric telescopic rods, the adsorbed fabric ends are staggered and tightly adhered, thus pre-folding the fabric into a cylinder before sewing. The ends to be sewn are staggered and overlapped, forming a pre-sewing state, facilitating subsequent sewing operations, reducing manual labor, effectively improving the efficiency of sewing filter bags, and reducing errors caused by manual stacking, thus avoiding insufficient sealing in the finished product.

[0017] 2. In this utility model, one end of the folded fabric is placed on the outer wall of guide roller 1 and located below guide roller 2. The mounting plate is moved down by electric telescopic rod 1, which in turn moves guide roller 2 down. This can press one end of the cylindrical fabric and further automatically process the shape of the fabric, making it flat. Guide roller 1, guide roller 2, and electric conveyor belt are used to transport the flat fabric, which facilitates subsequent sewing operations and further improves the efficiency of sewing work.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] A filter bag sewing and conveying device, such as Figures 1-6As shown, the conveyor for the fabric 3 to be sewn includes a base 1. A winding shaft 2 is rotatably connected to one end of the base 1. A mounting frame 6, a circular plate 7, and two side plates 4 are fixedly installed on the upper surface of the base 1. An electric conveyor belt 5 is installed between the two side plates 4. A control panel 24 is installed on the outer wall of the side plates 4. Several through slots 11 are provided on the outer wall of the circular plate 7. Multiple different through slots 11 are provided to accommodate fabrics 3 of different widths, assisting in bending the fabric 3 into a cylindrical shape. An auxiliary mechanism is provided on the upper surface of the base 1, located between the mounting frame 6 and the circular plate 7. The auxiliary mechanism includes two frames 8. A slider 19 is slidably connected inside each of the two frames 8. An electric telescopic rod 17 is installed at one end of each of the two sliders 19. A collection chamber 15 is fixedly installed at the output end of each of the two electric telescopic rods 17. Several suction heads 16 are installed on the bottom surface of each of the two collection chambers 15. The electric telescopic rod 17 can drive the two collection chambers 15 to move towards each other.

[0029] Both centralized chambers 15 are fixedly connected to a connecting pipe 18 on their upper surfaces. The connecting pipe 18 is connected to a vacuum pump. The suction head 16 generates negative pressure to adsorb the fabric 3. Two movable plates 20 are slidably connected inside the slider 19. Fixed rods 22 are fixedly connected to the outer walls of both movable plates 20. Several insertion holes 23 are opened on both inner side walls of the frame 8, and the insertion holes 23 are evenly distributed. One end of the fixed rod 22 fits into the insertion hole 23. A spring plate 21 is installed between the outer walls of the two movable plates 20. One end of the fixed rod 22 passes through the connecting pipe 18 and is movably installed inside the insertion hole 23. By sliding the two movable plates 20 along the inside of the slider 19, the two movable plates 20 are brought closer together, which can drive the two fixed rods 22 to move closer together. One end of the insertion rod 22 is moved out of the insertion hole 23, releasing the fixation between the slider 19 and the frame 8. The spring plate 21 is compressed and contracted. At this time, the slider 19 can be moved along the inside of the frame 8, driving the electric telescopic rod 17 and the concentrator 15 to move. The height of the concentrator 15 can be adjusted as needed. After adjustment, the movable plate 20 is released. Under the action of the spring plate 21, one end of the two fixed insertion rods 22 can be inserted into the corresponding two insertion holes 23, thus fixing the position between the slider 19 and the frame 8, thereby fixing the position of the concentrator 15. This allows for convenient adjustment of the height of the concentrator 15, facilitating the subsequent automatic staggered placement of the two ends of the fabric 3 bent into a cylindrical shape for sewing.

[0030] In use, one end of the fabric 3 wound on the winding shaft 2 is passed through the corresponding slot 11 on the circular plate 7, so that the fabric 3 is bent into a cylindrical shape and the two ends are close to each other. At this time, the fabric 3 bent into a cylindrical shape is located below the two collection chambers 15. Then, by adjusting the height of the two collection chambers 15, the suction heads 16 installed on the bottom surface of the two collection chambers 15 are pressed against the outer wall of the fabric 3. And through the connecting pipe 18, it is connected to an external vacuum pump, so that the suction heads 16 generate suction to adsorb the fabric 3. The height of one collection chamber 15 is lower than that of the other collection chamber 15. Then, through the two electric telescopic rods 17, the two collection chambers 15 are moved closer to each other, which can make the two ends of the adsorbed fabric 3 interlaced and pressed tightly. Thus, the fabric 3 to be sewn is pre-folded into a cylinder, and the two ends to be sewn are interlaced and overlapped, so that the two ends of the fabric 3 are interlaced and overlapped, forming a sewing preparation state, which facilitates the subsequent sewing operation, reduces manual labor, and effectively improves the working efficiency of sewing filter bags.

[0031] The mounting frame 6 has a rotatable guide roller 9 inside. Vertical grooves are opened through both outer walls of the mounting frame 6. A guide roller 10 is set between the two vertical grooves and above the guide roller 9. Both ends of the guide roller 10 are connected to the mounting plate 13 via shafts. A motor is installed on the outer wall of the mounting plate 13, and the output end of the motor is connected to the guide roller 10. A second motor is installed on the outer wall of the mounting frame 6, and the output end of the second motor is connected to one end of the guide roller 9. Electric telescopic rods 12 are installed at the top of the mounting frame 6 near both sides, and the output ends of the two electric telescopic rods 12 are fixedly connected to the mounting plate 13 respectively. The first motor drives the guide roller 10 to rotate counterclockwise, and the second motor drives the guide roller 9 to rotate clockwise, which can flatten the fabric 3 and convey it to the electric conveyor belt 5.

[0032] A control panel 24 is installed on the outer wall of the side panel 4. The output end of the control panel 24 is electrically connected to the input end of motor 1, motor 2, electric telescopic rod 12, electric telescopic rod 27 and electric conveyor belt 5. Control buttons and a display screen are installed on the outer wall of the control panel 24. The start and stop of motor 1, motor 2, electric telescopic rod 12, electric telescopic rod 27 and electric conveyor belt 5 can be conveniently controlled through the control buttons and display screen on the control panel 24. This is existing technology and will not be described in detail here. A support plate 14 is fixedly installed between the outer walls of the two side panels 4 and inside the electric conveyor belt 5. The electric conveyor belt 5 transports the fabric 3 to the sewing machine station, and the support plate 14 can support and reinforce the electric conveyor belt 5.

[0033] Specifically, after the fabric 3 is automatically folded into a cylindrical shape, one end of the folded fabric 3 is placed on the outer wall of guide roller 9 and located below guide roller 10. At this time, the mounting plate 13 is moved down by the electric telescopic rod 12, which in turn moves the guide roller 10 down, pressing one end of the cylindrical fabric 3 to make the fabric 3 flat. At this time, the guide rollers 9 and 10 are rotated simultaneously by motors 1 and 2 in opposite directions, which can convey the fabric 3 to the electric conveyor belt 5. The electric conveyor belt 5 is then started, which can continuously convey the flat and symmetrically aligned fabric 3, and can be sewn by the sewing machine.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
