Description

Technical Field

[0001] The utility model relates to the field of automobile part production equipment, in particular to a welding and cutting integrated device for non-woven fabrics. Background Art

[0002] A fuel filter is a common automobile part, and its main function is to prevent impurities in the fuel from entering the fuel pump and causing blockage. The fuel filter is usually composed of a skeleton and non-woven fabrics connected to the skeleton. During the production process, the non-woven fabrics need to be welded, cut, and then fixed on the skeleton. During the welding process of the non-woven fabrics, the two ends of the non-woven fabrics need to be welded together, and then according to the production requirements, the non-woven fabrics are cut into corresponding lengths to form non-woven fabric cylinders of corresponding sizes. The following problems exist in the non-woven fabric cutting device and non-woven fabric welding device in the prior art: First, after welding is completed, there will be waste materials at the welding position, and in the prior art, it is usually necessary for workers to manually remove the waste materials, which will affect the subsequent work efficiency; Second, the existing processing equipment can usually only process non-woven fabrics of one size, which will greatly increase the production cost. Summary of the Invention

[0003] In order to solve the above problems, the utility model provides a welding and cutting integrated device for non-woven fabrics, which can improve the processing efficiency, automatically remove waste materials, and meet the processing requirements of non-woven fabrics of different sizes.

[0004] Technical solution of the utility model: A welding and cutting integrated device for non-woven fabrics, comprising an equipment base, a feeding device connected to the equipment base, a welding device connected to the equipment base, a cutting device connected to the equipment base, a waste removal device connected to the equipment base, a finished product collection bin connected to the equipment base, and a controller. The feeding device includes a first coil reel connected to the equipment base, a first roller shaft connected to the equipment base, a second roller shaft connected to the equipment base, a first rotating motor for driving the first roller shaft to rotate, and a second rotating motor for driving the second roller shaft to rotate. The welding device includes a support platform connected to the equipment base and a welding element connected to the equipment base. The non-woven fabric passes through the gap between the support platform and the welding element. The cutting device includes a third roller shaft connected to the equipment base, a fourth roller shaft connected to the equipment base, a third rotating motor for driving the third roller shaft to rotate, a fourth rotating motor for driving the fourth roller shaft to rotate, a first fixing frame connected to the equipment base, a first sliding base slidably connected to the first fixing frame, a cutting element connected to the first sliding base, and a first hydraulic cylinder for driving the first sliding base to move in the vertical direction. The finished product collection bin is located directly below the cutting element. The rotation directions of the first roller shaft and the third roller shaft are opposite to those of the second roller shaft and the fourth roller shaft respectively. The waste removal device includes a second fixing frame connected to the equipment base and a cutting tool head connected to the second fixing frame. The waste removal device is located between the welding device and the cutting device. The position of the cutting tool head corresponds to the weld position of the non-woven fabric. The controller is electrically connected to the first rotating motor, the second rotating motor, the third rotating motor, the fourth rotating motor, the first hydraulic cylinder, and the welding element.

[0005] With the above technical solution, first, place the non-woven fabric to be processed on the first coiling reel. Then, pull out one end of the non-woven fabric, fold the non-woven fabric, and feed the folded non-woven fabric so that it passes through the gap between the first roller and the second roller. At the same time, it also needs to pass through the gap between the third roller and the fourth roller. Then, control the rotation of the first rotary motor, the second rotary motor, the third rotary motor, and the fourth rotary motor respectively through the controller. Among them, the rotation directions of the first roller and the third roller are opposite to those of the second roller and the fourth roller respectively. In this way, the friction between the first roller and the second roller and the friction between the third roller and the fourth roller can drive the continuous feeding of the non-woven fabric. Then, control the welding element to work through the controller so that when the non-woven fabric passes between the welding element and the support platform, the welding element welds the two ends of the non-woven fabric together. When the non-woven fabric moves to the position where the cutting blade is located, since the position of the cutting blade corresponds to the weld position of the non-woven fabric, the cutting blade will cut off the excess non-woven fabric waste at the weld position, automatically completing the waste removal work. When the non-woven fabric is welded and moves directly below the cutting element, control the first hydraulic cylinder to drive the first sliding base to move vertically downward through the controller. After the cutting element completes the cutting work, the first sliding base moves vertically upward, and the cut non-woven fabric falls into the finished product collection bin, thus automatically completing the welding and cutting work of the non-woven fabric.

[0006] Further setting of the present utility model: The welding element includes an ultrasonic generator and a flower wheel element. The flower wheel element contacts the support platform, and the controller is electrically connected to the ultrasonic generator.

[0007] With the above technical solution, since the welding element includes an ultrasonic generator and a flower wheel element, and the flower wheel element contacts the support platform, when the seam position of the non-woven fabric passes through the bottom of the flower wheel element, the controller controls the ultrasonic generator to emit ultrasonic waves, so that the seam of the non-woven fabric is welded together. At the same time, the seam position will be pressed out with patterns by the flower wheel element, which is more convenient for the subsequent cutting blade to cut off the waste.

[0008] Further setting of the present utility model: The feeding device includes several connecting shafts connected to the equipment base, a second sliding base slidably connected to the equipment base, a top sheet fixedly connected to the second sliding base, and a second hydraulic cylinder for driving the second sliding base to move horizontally. The non-woven fabric bypasses each connecting shaft in turn. When the non-woven fabric is folded, the top sheet is located at the fold of the non-woven fabric, and the controller is electrically connected to the second hydraulic cylinder.

[0009] With the above technical solution, since the non-woven fabric bypasses each connecting shaft in turn, it can ensure that the non-woven fabric remains in a taut state during the feeding process. Since the top material piece is located at the crease of the non-woven fabric after the non-woven fabric is folded, when processing non-woven fabrics of different sizes, according to user requirements, the controller can control the second hydraulic cylinder to drive the second sliding base to slide horizontally, so that during the feeding process of the non-woven fabric, the size of the folded non-woven fabric remains fixed, and the size of the folded non-woven fabric can meet the processing requirements.

[0010] A further setting of the present utility model: A third sliding base slidably connected to the second fixing frame and a third hydraulic cylinder for driving the third sliding base to move horizontally are provided on the second fixing frame. The cutting tool head is fixedly connected to the third sliding base. A waste collection tray and a fifth rotating motor for driving the waste collection tray to rotate are also provided on the second fixing frame. The waste cut from the non-woven fabric is wound on the waste collection tray. The controller is electrically connected to the third hydraulic cylinder and the fifth rotating motor respectively.

[0011] With the above technical solution, since the position of the waste at the seam of the welded non-woven fabric may change after the processing size of the non-woven fabric is changed, the controller controls the third hydraulic cylinder to drive the third sliding base to slide horizontally, so that the position of the cutting tool head corresponds to the position of the waste of the welded non-woven fabric. At the same time, the controller controls the fifth rotating motor to rotate, so that the waste collection tray rotates continuously, and the cut waste is wound on the waste collection tray, further ensuring the automation degree of the device.

Detailed Embodiments

[0014] As shown Figure 1 in the figure, a welding and cutting integrated device for non-woven fabrics includes a device base 1, a feeding device 2 connected to the device base 1, a welding device 3 connected to the device base 1, a cutting device 4 connected to the device base 1, a waste removal device 5 connected to the device base 1, a finished product collection bin 6 connected to the device base 1, and a controller 7. The feeding device 2 includes a first coil reel 8 connected to the device base 1, a first roller 9 connected to the device base 1, a second roller 10 connected to the device base 1, a first rotating motor 11 for driving the first roller 9 to rotate, and a second rotating motor 12 for driving the second roller 10 to rotate. The welding device 3 includes a support platform 13 connected to the device base 1 and a welding element 14 connected to the device base 1. The non-woven fabric passes through the gap between the support platform 13 and the welding element 14. The cutting device 4 includes a third roller 15 connected to the device base 1, a fourth roller 16 connected to the device base 1, a third rotating motor 17 for driving the third roller 15 to rotate, a fourth rotating motor 18 for driving the fourth roller 16 to rotate, a first fixing frame 19 connected to the device base 1, a first sliding base 20 slidably connected to the first fixing frame 19, a cutting element 21 connected to the first sliding base 20, and a first hydraulic cylinder 22 for driving the first sliding base 20 to move in the vertical direction. The finished product collection bin 6 is located directly below the cutting element 21. The rotation directions of the first roller 9 and the third roller 15 are opposite to those of the second roller 10 and the fourth roller 16 respectively. The waste removal device 5 includes a second fixing frame 23 connected to the device base 1 and a cutting knife head 24 connected to the second fixing frame 23. The waste removal device 5 is located between the welding device 3 and the cutting device 4. The position of the cutting knife head 24 corresponds to the weld position of the non-woven fabric. The controller 7 is electrically connected to the first rotating motor 11, the second rotating motor 12, the third rotating motor 17, the fourth rotating motor 18, the first hydraulic cylinder 22, and the welding element 14.

[0015] First, place the non-woven fabric to be processed on the first coil reel 8, then pull out one end of the non-woven fabric, fold the non-woven fabric, and then feed the folded non-woven fabric so that it passes through the gap between the first roller 9 and the second roller 10. At the same time, it also needs to pass through the gap between the third roller 15 and the fourth roller 16. Then, control the rotation of the first rotary motor 11, the second rotary motor 12, the third rotary motor 17, and the fourth rotary motor 18 respectively through the controller 7. Among them, the rotation directions of the first roller 9 and the third roller 15 are opposite to those of the second roller 10 and the fourth roller 16 respectively. In this way, the friction between the first roller 9 and the second roller 10 and the friction between the third roller 15 and the fourth roller 16 can drive the continuous feeding of the non-woven fabric. Then, control the welding element 14 to work through the controller 7 so that when the non-woven fabric passes between the welding element 14 and the support platform 13, the welding element 14 welds the two ends of the non-woven fabric together. When the non-woven fabric moves to the position where the cutting blade 24 is located, since the position of the cutting blade 24 corresponds to the weld position of the non-woven fabric, the cutting blade 24 will cut off the excess non-woven fabric waste at the weld position, automatically completing the waste removal work. When the non-woven fabric is welded and moves directly below the cutting element 21, control the first hydraulic cylinder 22 to drive the first sliding base 20 to move vertically downward through the controller 7. After the cutting element 21 completes the cutting work, the first sliding base 20 moves vertically upward, and the cut non-woven fabric falls into the finished product collection bin 6, so that the welding and cutting work of the non-woven fabric can be completed automatically.

[0016] The welding element 14 includes an ultrasonic generator 25 and a flower wheel element 26. The flower wheel element 26 is in contact with the support platform 13, and the controller 7 is electrically connected to the ultrasonic generator 25. Since the welding element 14 includes an ultrasonic generator 25 and a flower wheel element 26, and the flower wheel element 26 is in contact with the support platform 13, when the seam position of the non-woven fabric passes under the flower wheel element 26, the controller 7 controls the ultrasonic generator 25 to emit ultrasonic waves, so that the seams of the non-woven fabric are welded together. At the same time, the seam position will be pressed out with patterns by the flower wheel element 26, which is more convenient for the subsequent cutting blade 24 to cut off the waste.

[0017] The feeding device 2 includes several connecting shafts 27 connected to the equipment base 1, a second sliding base 28 slidably connected to the equipment base 1, a blanking piece 29 fixedly connected to the second sliding base 28, and a second hydraulic cylinder 30 for driving the second sliding base 28 to move horizontally. The non-woven fabric bypasses each connecting shaft 27 in sequence. When the non-woven fabric is folded, the blanking piece 29 is located at the crease of the non-woven fabric. The controller 7 is electrically connected to the second hydraulic cylinder 30. Since the non-woven fabric bypasses each connecting shaft 27 in sequence, it can ensure that the non-woven fabric is always in a taut state during the feeding process. Since the blanking piece 29 is located at the crease of the non-woven fabric when the non-woven fabric is folded, when processing non-woven fabrics of different sizes, according to user requirements, the controller 7 can control the second hydraulic cylinder 30 to drive the second sliding base 28 to slide horizontally, so that during the feeding process of the non-woven fabric, the size of the folded non-woven fabric remains fixed, and the size of the folded non-woven fabric can meet the processing requirements.

[0018] The second fixing frame 23 is provided with a third sliding base 31 slidably connected to the second fixing frame 23 and a third hydraulic cylinder 32 for driving the third sliding base 31 to move horizontally. The cutting tool head 24 is fixedly connected to the third sliding base 31. The second fixing frame 23 is also provided with a waste collection tray 33 and a fifth rotating motor 34 for driving the waste collection tray 33 to rotate. The waste cut from the non-woven fabric is wound on the waste collection tray 33. The controller 7 is electrically connected to the third hydraulic cylinder 32 and the fifth rotating motor 34 respectively.

[0019] Since the position of the waste at the seam of the welded non-woven fabric may change after the processing size of the non-woven fabric is changed, the controller 7 controls the third hydraulic cylinder 32 to drive the third sliding base 31 to slide horizontally, so that the position of the cutting tool head 24 corresponds to the position of the waste of the welded non-woven fabric. At the same time, the controller 7 controls the fifth rotating motor 34 to rotate, so that the waste collection tray 33 rotates continuously, and the cut waste is wound on the waste collection tray 33, further ensuring the automation degree of the device.
