Abstract

This utility model relates to the field of air shaft technology, specifically a non-stop air shaft winding loading and unloading mechanism, including a first support plate, one end of which is rotatably connected to two feeding rollers. This utility model, through the setting of an adjustment structure and a pressing structure, allows for continuous winding of material by an air bladder after one air bladder has finished winding the material. A second motor drives a transmission rod to rotate, and the turntable, under the rotation of the transmission rod, moves the wound air bladder. A second cylinder fixed on a fixed frame drives a first air rod to move, and the mounting base, pushed by the first air rod, drives a moving plate to rotate on the first support plate, thereby adjusting the angle of the pressing rollers and pressing the roll material onto another unused air bladder. A cutting blade cuts the wound roll material, and the cut roll material, under the pressure of the pressing rollers, is fixed onto another air bladder for winding. This allows for continuous winding of the roll material without stopping the machine, improving winding efficiency.

Description

Technical Field

[0001] This utility model relates to the field of air shafts, and in particular to a non-stop rewinding air shaft loading and unloading mechanism. Background Technology

[0002] Air shafts are a special type of shaft component widely used in the winding industry. Their core concept is to achieve quick, flexible loading and unloading and secure fixing between the shaft and the roll material through internal air pressure regulation. They consist of a shaft, an air nozzle, and an internal expandable rubber or air bladder structure, and are widely used in winding processes such as slitting, rewinding, and coating in industries such as printing, papermaking, textiles, and packaging.

[0003] Because the machine needs to be stopped during processing to continuously place and remove both the processed and unprocessed rolls, the equipment cannot operate continuously, resulting in reduced winding efficiency. Furthermore, the need for workers to continuously adjust their movements to place the rolls can easily cause physical injury to the workers. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a non-stop winding air shaft loading and unloading mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a non-stop winding air shaft loading and unloading mechanism, comprising a first support plate, one end of which is rotatably connected to two feeding rollers, a guide roller rotatably connected to the end of the first support plate near the feeding rollers, a winding structure provided on the side of the first support plate near the guide rollers, an adjustment structure provided on the side of the winding structure near the first support plate, a material receiving and unloading structure provided at the bottom end of the side of the first support plate near the winding structure, and a material pressing structure provided on the side of the first support plate near the guide rollers.

[0006] Furthermore, the adjustment structure includes a turntable, which is rotatably connected to one end of a first support plate near the guide roller. A second motor is fixedly connected inside the turntable near the first support plate. A transmission rod is driven to the side of the second motor near the turntable, and the transmission rod is fixedly connected to the turntable.

[0007] Furthermore, the winding structure includes a first motor, a plurality of the first motors are fixedly connected in a ring array to one end of the turntable near the second motor, and the transmission shaft of one end of the first motor passes through the turntable and is rotatably connected to the turntable. A winding roller is fixedly connected to the output shaft of one end of the first motor, and an air bladder is fixedly connected to the outer wall of the winding roller.

[0008] Furthermore, the material receiving and discharging structure includes a placement box, which is fixedly connected to the bottom end of the first support plate near the airbag. A third motor is fixedly connected to the end of the placement box away from the first support plate. A lead screw is driven to the side of the third motor near the placement box, and the lead screw is rotatably connected to the placement box. A movable seat is threaded to the outer wall of the lead screw, and the movable seat is slidably connected to the placement box.

[0009] Furthermore, a first cylinder is fixedly connected to both sides of the top of the movable seat, and a second support plate is fixedly connected to the second air rod of the first cylinder at the end away from the movable seat.

[0010] Furthermore, the pressing structure includes a fixed frame, which is fixedly connected to the top of the first support plate near the guide roller. A second cylinder is fixedly connected to the end of the fixed frame away from the first support plate, and a first air rod is drivenly connected to the end of the second cylinder away from the fixed frame.

[0011] Furthermore, a mounting base is rotatably connected to the side of the first air rod away from the second air cylinder, and a movable plate is fixedly connected to the end of the mounting base away from the first air rod. The movable plate is rotatably connected to the first support plate, and a pressure roller is fixedly connected to the end of the movable plate near the air bag.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting an adjustment structure and a pressing structure, after one airbag finishes winding the material, the second motor drives the transmission rod to rotate. The turntable moves the wound airbag under the rotation of the transmission rod. The second cylinder fixed on the fixed frame moves the first air rod. The mounting seat drives the moving plate to rotate on the first support plate under the push of the first air rod, so that the angle of the pressing roller is adjusted and the roll material is pressed on another unused airbag. The cutting blade cuts the wound roll material. The cut roll material is fixed on another airbag and wound up under the pressure of the pressing roller. It can continuously wind up the roll material without stopping the machine, thus improving the winding efficiency.

[0014] 2. In this utility model, by setting a receiving and feeding structure, the core is placed on a second support plate. Two first cylinders operate to adjust the height of the two second support plates. A third motor fixed on the placement box operates, and the lead screw drives the moving seat to move under the operation of the third motor. The core on one second support plate coincides with the air bladder under the movement of the moving seat. The air bladder inflates and expands to support and fix the core. The other second support plate supports the wound material. The air bladder contracts and loses its fixation on the core, so that the wound material loses its limiting support and is placed on the other second support plate. The third motor operates to move the two second support plates out from the multiple air bladders respectively. The reciprocating movement of the two second support plates facilitates the removal of the wound material and the automatic placement of the core. Attached Figure Description

[0022] Please see Figure 1-5This utility model provides a technical solution: a non-stop winding air shaft loading and unloading mechanism, including a first support plate 1, one end of the first support plate 1 is rotatably connected to two feeding rollers 11, the end of the first support plate 1 near the feeding rollers 11 is rotatably connected to a guide roller 12, a winding structure is provided on the side of the first support plate 1 near the guide roller 12, an adjustment structure is provided on the side of the winding structure near the first support plate 1, a material receiving and unloading structure is provided at the bottom end of the side of the first support plate 1 near the winding structure, and a material pressing structure is provided on the side of the first support plate 1 near the guide roller 12.

[0023] Please see Figures 1 to 3 The adjustment structure includes a turntable 2, which is rotatably connected to one end of the first support plate 1 near the guide roller 12. A second motor 21 is fixedly connected inside the turntable 2 near the first support plate 1. A transmission rod 22 is driven to the side of the second motor 21 near the turntable 2, and the transmission rod 22 is fixedly connected to the turntable 2. The pressing structure includes a fixed frame 4, which is fixedly connected to the top of the first support plate 1 near the guide roller 12. A second cylinder 41 is fixedly connected to the end of the fixed frame 4 away from the first support plate 1. A first air rod 42 is driven to the end of the second air rod 41 away from the fixed frame 4. A mounting base 43 is rotatably connected to the side of the first air rod 42 away from the second air rod 41. A moving plate 44 is fixedly connected to the end of the mounting base 43 away from the first air rod 42, and the moving plate 44 is rotatably connected to the first support plate 1. A pressing roller 45 is fixedly connected to the end of the moving plate 44 near the airbag 133.

[0024] In this embodiment, after one airbag 133 finishes winding the material, the second motor 21 drives the transmission rod 22 to rotate. The turntable 2 moves the wound airbag 133 under the rotation of the transmission rod 22. The second cylinder 41, fixed on the fixed frame 4, drives the first air rod 42 to move. The mounting base 43 drives the moving plate 44 to rotate on the first support plate 1 under the push of the first air rod 42, so that the angle of the pressure roller 45 is adjusted and the roll material is pressed on another unused airbag 133. The cutting blade cuts the wound roll material. The cut roll material is fixed on another airbag 133 and wound up under the pressure of the pressure roller 45. The roll material can be continuously wound up without stopping the machine, which improves the winding efficiency.

[0025] Please see Figure 1 and Figure 2 The winding structure includes a first motor 131. Multiple first motors 131 are fixedly connected in a ring array to one end of the turntable 2 near the second motor 21. The drive shaft of one end of the first motor 131 passes through the turntable 2 and is rotatably connected to the turntable 2. A winding roller 132 is fixedly connected to the output shaft of one end of the first motor 131. An airbag 133 is fixedly connected to the outer wall of the winding roller 132.

[0026] In this embodiment, air is injected into the airbag 133 through the air nozzle, causing the airbag 133 to expand and limit and fix the core. The first motor 131 operates, and the take-up roller 132 rotates under the operation of the first motor 131. The airbag 133 takes up the roll material under the rotation of the take-up roller 132.

[0027] Please see Figure 2 , Figure 4 as well as Figure 5 The material receiving and discharging structure includes a placement box 3, which is fixedly connected to the bottom end of the first support plate 1 near the airbag 133. A third motor 31 is fixedly connected to the end of the placement box 3 away from the first support plate 1. A lead screw 32 is driven to the side of the third motor 31 near the placement box 3, and the lead screw 32 is rotatably connected to the placement box 3. A movable seat 33 is threaded to the outer wall of the lead screw 32, and the movable seat 33 is slidably connected to the placement box 3. A first cylinder 34 is fixedly connected to both sides of the top of the movable seat 33. A second support plate 35 is fixedly connected to the second air rod of the first cylinder 34 away from the movable seat 33.

[0028] In this embodiment, the core is placed on a second support plate 35. Two first cylinders 34 operate to adjust the height of the two second support plates 35. A third motor 31 fixed on the placement box 3 operates, and the lead screw 32 drives the moving seat 33 to move under the operation of the third motor 31. The core on one second support plate 35 overlaps with the air bag 133 under the movement of the moving seat 33. The air bag 133 inflates and expands to support and fix the core. The other second support plate 35 supports the wound material. The air in the air bag 133 contracts and loses its fixation on the core, so that the wound material loses its limiting support and is placed on the other second support plate 35. The third motor 31 operates to move the two second support plates 35 out of the multiple air bags 133 respectively. The reciprocating movement of the two second support plates 35 facilitates the removal of the wound material and the automatic placement of the core.

[0029] Working principle: The roll material is fed through two feeding rollers 11 and placed on guide roller 12. Guide roller 12 guides the roll material onto an air bladder 133. Air is injected into the air bladder 133 through an air nozzle, causing the air bladder 133 to expand and limit and fix the roll core. The first motor 131 drives the take-up roller 132 to rotate. The air bladder 133, under the rotation of the take-up roller 132, winds up the roll material and places the roll core on a second support plate 35. Two first cylinders 34 operate to adjust the height of the two second support plates 35. The third motor 31, fixed on the placement box 3, operates, and the lead screw 32 is driven by the third motor 31. The operation of motor 1 drives the moving seat 33 to move. The core on one of the second support plates 35 overlaps with the air bag 133 as the moving seat 33 moves. The air bag 133 expands to support and fix the core. The other second support plate 35 supports the wound material. The air bag 133 contracts and loses its fixation on the core, so that the wound material loses its limiting support and is placed on the other second support plate 35. The third motor 31 operates to move the two second support plates 35 out of the multiple air bags 133 respectively. The reciprocating movement of the two second support plates 35 facilitates the removal of the wound material and the automatic placement of the core.

[0030] Next, after one airbag 133 finishes winding the material, the second motor 21 drives the transmission rod 22 to rotate. The turntable 2 moves the wound airbag 133 under the rotation of the transmission rod 22. The second cylinder 41, fixed on the fixed frame 4, drives the first air rod 42 to move. The mounting base 43 drives the moving plate 44 to rotate on the first support plate 1 under the push of the first air rod 42, so that the pressure roller 45 adjusts the angle and presses the roll material onto another unused airbag 133. The cutting blade cuts the wound roll material. The cut roll material is fixed on another airbag 133 and wound up under the pressure of the pressure roller 45, which can continuously wind up the roll material without stopping the machine.
