Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of material feeding, specifically an alternating continuous material feeding mechanism. Background Technology
[0002] Coated fabric is a type of fabric that is waterproof and windproof by uniformly coating an adhesive onto its surface. This type of fabric is widely used in applications requiring a certain thickness and protective function, such as insulating tape and raincoats. Currently, common production methods for coated fabrics include blade coating, roller coating, dip coating, and spray coating, which can be used individually or in combination.
[0003] According to Chinese Patent No. CN220925755U, a chemical fiber fabric placement mechanism includes a base and two opposing support frames slidably connected to the base. A drive motor for driving the take-up roller to rotate is mounted on each support frame. A take-up roller is positioned between the two support frames. The take-up roller includes a left support roller, several telescopic rollers, and a right support roller connected sequentially along the axial direction. The left support roller is movably connected to the output shaft of the drive motor, and the right support roller is movably connected to the right support frame. Several telescopic rollers are connected between the left and right support rollers. Roller columns are provided on the left side of the telescopic roller and the left side of the right support roller. Openings are provided on the right side of the telescopic roller and the right side of the left support roller. Support wings are provided on the outer side of the roller columns, and slots adapted to the support wing structure are provided in the openings.
[0004] In the above scheme, the fabric is fed by rotating the support roller and the telescopic roller. However, this still has the following disadvantages: after the fabric on the current support roller and the telescopic roller is fed out, the fabric on the support roller and the telescopic roller needs to be replaced and replenished. The time spent in the process of replacing and replenishing the fabric prevents the equipment from continuing to work, which reduces the single working time of the equipment and reduces the processing efficiency of the equipment for the fabric. Utility Model Content
[0005] The purpose of this invention is to provide an alternating continuous feeding mechanism to solve the problem of time wasted during the replacement and replenishment of fabric, which prevents the equipment from continuing to work, reduces the single working time of the equipment, and reduces the processing efficiency of the equipment for fabric.
[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: an alternating continuous feeding mechanism, including a base frame, a plurality of support plates fixed on the top surface of the base frame, wherein two support plates form a group, a fixing plate is fixed above each group of support plates, a connecting plate is fixed on the top surface of the fixing plate, a fixing folding plate is fixed on one side of each of the two rear support plates, a magnetic powder brake is fixed on one side of the fixing folding plate, a drive gear is fixed on the output shaft of the magnetic powder brake, two air expansion shafts are rotatably arranged on the connecting plate, a driven gear is fixedly inserted at one end of the air expansion shaft, the drive gear and the driven gear mesh with each other, bearings are fixedly inserted at both ends of the air expansion shaft, and the bearings are fixedly inserted into the interior of the connecting plate.
[0007] Preferably, the top surface of the bottom frame is fixed with two fixed arc plates, and a first winding roller is rotatably inserted inside the fixed arc plates. The top surface of the bottom frame is fixed with two positioning arc plates, and a second winding roller is rotatably inserted inside the positioning arc plates.
[0008] Preferably, a mounting plate is fixed to one side of each of the two front support plates, and a movable plate is slidably disposed on one side of the mounting plate. A screw rod is threadedly connected to the movable plate, and one end of the screw rod is rotatably disposed with one side of the mounting plate. A limit post is fixed to the top surface of the movable plate, and a limit groove is formed on the surface of the air shaft. The limit post and the limit groove are slidably disposed.
[0009] Preferably, two stabilizing rods are fixed on one side of the mounting plate, and two stabilizing holes are opened on one side of the movable plate, with the stabilizing holes and stabilizing rods slidably inserted into each other.
[0010] Preferably, two support frames are fixed on the top surface of the bottom frame, a tension sensor is fixed on the top surface of the support frame, a connecting arc plate is provided on the top surface of the tension sensor, and an inspection roller is rotatably inserted in the connecting arc plate.
[0011] Preferably, the bottom surface of the base frame is fixed with several anti-slip pads.
[0012] Compared with existing technologies, the alternating continuous feeding mechanism that adopts the above technical solution has the following advantages:
[0013] 1. Material rolls are fitted on both air expansion shafts. First, the worker will unwind the material roll on the right air expansion shaft around the second winding roller and continue to extend it. As the material roll on the right air expansion shaft is unwound, the worker will pull the material roll on the left air expansion shaft around the first winding roller and continue to extend it. This seamlessly fills the time when changing material rolls, thus maintaining continuous and uninterrupted material feeding for a long time, extending the working time of the equipment and increasing the processing efficiency of the equipment.
[0014] 2. Before the material roll is unwound, the staff will adjust the position of the air shaft according to the position of the first winding roller and the second winding roller. During the adjustment, the staff will rotate the screw rod. According to the rotation direction of the screw rod, the movable plate can be driven to slide back and forth by the threaded connection with the movable plate. During the sliding process, the movable plate can drive the limit post to move synchronously. The position of the air shaft can be adjusted by the sliding setting with the limit groove, which can increase the flatness of the material roll when it is unwound.
[0015] 3. When the material roll is unwound, the material will bypass the inspection roller and apply pressure to the inspection roller. At this time, the tension sensor will respond to the pressure and convert the pressure change into an easily processed electrical signal through the built-in strain gauge or other sensing element. The electrical signal is then transmitted to the control system. The PID control algorithm processes the tension value transmitted by the sensor and compares it with the preset tension value to obtain the current unwound tension value, so as to make timely adjustments.

A magnetic powder brake 6 is fixed on one side of the fixing folding plate 5. A drive gear 7 is fixed on the output shaft of the magnetic powder brake 6. Two air expansion shafts 9 are rotatably arranged on the connecting plate 4. A driven gear 8 is fixedly inserted at one end of the air expansion shaft 9. The drive gear 7 and the driven gear 8 mesh with each other. Bearings 10 are fixedly inserted at both ends of the air expansion shaft 9. The bearings 10 are fixedly inserted into the interior of the connecting plate 4. Two fixing arc plates 11 are fixed on the top surface of the base frame 1. A first winding roller 12 is rotatably inserted inside the fixing arc plate 11. Two positioning arc plates 13 are fixed on the top surface of the base frame 1. A second winding roller 14 is rotatably inserted inside the positioning arc plate 13.
[0023] During use, material rolls are fitted onto both air expansion shafts 9. First, the operator will unwind the material roll on the right air expansion shaft 9 around the second winding roller 14 and continue to extend it. As the material roll on the right air expansion shaft 9 finishes unwinding, the operator will pull the material roll on the left air expansion shaft 9 around the first winding roller 12 and continue to extend it. This seamlessly fills the time when changing material rolls, thus maintaining continuous and uninterrupted material feeding for a long time, extending the working time of the equipment, and increasing the processing efficiency of the equipment.
[0024] like Figure 2 and Figure 3 As shown, a mounting plate 15 is fixed to one side of the two front support plates 2. A movable plate 16 is slidably arranged on one side of the mounting plate 15.

A limit post 18 is fixed to the top surface of the movable plate 16. A limit groove 19 is opened on the surface of the air shaft 9. The limit post 18 and the limit groove 19 are slidably arranged. Two stabilizing rods 20 are fixed to one side of the mounting plate 15. Two stabilizing holes 21 are opened on one side of the movable plate 16. The stabilizing holes 21 and the stabilizing rods 20 are slidably inserted.
[0025] In use, before the material roll is unwound, the operator will adjust the position of the air shaft 9 according to the positions of the first winding roller 12 and the second winding roller 14. During the adjustment, the operator will rotate the screw rod 17. According to the rotation direction of the screw rod 17, the movable plate 16 can be driven to slide back and forth by the threaded connection with the movable plate 16. During the sliding process, the movable plate 16 can drive the limit post 18 to move synchronously. The position of the air shaft 9 can be adjusted by the sliding setting with the limit groove 19, thereby increasing the flatness of the material roll when it is unwound.
[0026] like Figure 1 and Figure 4As shown, two support frames 22 are fixed on the top surface of the bottom frame 1, a tension sensor 23 is fixed on the top surface of the support frame 22, a connecting arc plate 24 is provided on the top surface of the tension sensor 23, an inspection roller 25 is rotatably inserted in the connecting arc plate 24, and several anti-slip pads 26 are fixed on the bottom surface of the bottom frame 1.
[0027] During use, when the material roll is unwound, the material will bypass the inspection roller 25 and apply pressure to the inspection roller 25. At this time, the tension sensor 23 will react to the pressure and convert the pressure change into an easily processed electrical signal through the built-in strain gauge or other sensing element. The electrical signal is then transmitted to the control system. The tension value transmitted by the sensor is processed by the PID control algorithm and compared with the preset tension value to obtain the current unwinding tension value, so as to make timely adjustments.
