Description

Technical Field

[0001] This utility model relates to the field of automatic film winding machine technology, and specifically discloses an automatic film winding machine with efficient feeding function. Background Technology

[0002] Thin films are thin, flexible, transparent sheet-like materials made of materials such as plastics, adhesives, and rubber. Scientifically, they are defined as two-dimensional structures formed by the deposition of atoms, molecules, or ions on a substrate surface. In industrial production, the initial master roll is often too large to be directly adapted to the needs of downstream equipment (such as packaging machines and printing presses). After the master roll is unwound, the equipment needs to rewind it into smaller rolls (sub-rolls) that meet the required specifications for subsequent use.

[0003] In the existing technology, the operation process of automatic film winding is as follows: First, the master roll is placed on the unwinding shaft, and the take-up drum is fixed on the take-up shaft; then, the starting end of the master roll is pulled and wound around the outer wall of the take-up drum; finally, the automatic winding of the master roll is achieved by driving the take-up drum to rotate.

[0004] With the rapid development of technology, the traditional feeding methods of film winding machines are no longer sufficient. Due to the large diameter and heavy weight of the master roll, and the fact that the unwinding shaft is usually quite tall, manual labor is required to move the master roll and place it onto the unwinding shaft, resulting in high labor intensity and low feeding efficiency. Furthermore, many machines lack a tensioning mechanism, making the roll prone to loosening during the winding process. Therefore, there is an urgent need for an automatic film winding machine with efficient feeding capabilities to solve these problems. Utility Model Content

[0005] This utility model proposes an automatic film winding machine with efficient feeding function, which can conveniently complete the feeding of master rolls, significantly reduce labor intensity and improve feeding efficiency; and effectively avoids the problem of loose rolls during the winding process.

[0006] This utility model is implemented as follows: an automatic film winding machine with efficient feeding function includes a frame, a master roll and a winding mechanism. The frame is slidably connected to a lifting plate through two sliding grooves and two sliders. A driving mechanism is provided on the upper side of the lifting plate.

[0007] A clamping mechanism is provided on the lower side of the lifting plate. The clamping mechanism includes two connecting plates installed at the lower end of the lifting plate. A bidirectional lead screw is rotatably connected between the two connecting plates. The bidirectional lead screw is driven by a first drive motor installed on the outer wall of the left connecting plate. Two translation plates are threadedly connected to the outer wall of the bidirectional lead screw. A pressure column is slidably connected through a guide hole on the outer wall of the left translation plate. A pressure sensor that abuts against the pressure column is installed on the left side of the left translation plate through a U-shaped frame. A clamping cover is rotatably connected to the outer wall of the pressure column through a first bearing. A controller is installed at the lower end of the lifting plate. A second bearing is fixedly connected through the outer wall of the right translation plate. A shaft is fixedly connected to the inner wall of the second bearing. A clamping plate is fixedly connected to the left end of the shaft. A positioning rod is installed on the side of the clamping plate opposite to the clamping cover.

[0008] A tensioning mechanism is provided on the right side of the right-side translation plate. The tensioning mechanism includes an anti-slip disc installed on the right end of the shaft. A pressure block is provided on the outer wall of the anti-slip disc to abut against it. A horizontal plate is fixedly connected to the right end of the right-side translation plate. A compression spring is installed between the horizontal plate and the pressure block.

[0009] As a preferred embodiment of the present invention, an automatic film winding machine with efficient feeding function includes a winding mechanism comprising a flat plate fixedly connected to the front end of a frame, a vertical plate mounted on the upper end of the flat plate, an air shaft rotatably connected to the right end of the vertical plate, a winding drum provided on the outer wall of the air shaft, and a second drive motor whose output end is fixedly connected to the air shaft mounted on the outer wall of the vertical plate.

[0010] As a preferred embodiment of the present invention, an automatic film winding machine with efficient feeding function includes a drive mechanism comprising an internally threaded cylinder fixedly connected to the upper end of a lifting plate, a screw extending into and threadedly connected to the internally threaded cylinder and rotatably connected to the top end of the inner wall of the frame, and a third drive motor whose output end is fixedly connected to the screw is installed at the upper end of the frame.

[0011] As a preferred embodiment of the present invention, an automatic film winding machine with efficient feeding function is provided, wherein a circular hole is provided through the outer wall of the horizontal plate, and a retaining rod is installed at the upper end of the pressure block, which is sleeved inside the compression spring and passes through the circular hole. Two sliding grooves are provided on the outer wall of the retaining rod, and a slider that is fixedly connected to the inner wall of the circular hole is slidably connected inside the two sliding grooves.

[0012] As a preferred embodiment of the present invention, an automatic film rolling machine with efficient feeding function is provided with a sliding groove at the lower end of the lifting plate, and a slider that is slidably connected to the inside of the sliding groove is installed at the upper end of both translation plates.

[0013] As a preferred embodiment of the present invention, an automatic film winding machine with efficient feeding function, both the first drive motor and the third drive motor are worm gear motors.

[0014] As a preferred embodiment of this utility model of an automatic film winding machine with efficient feeding function, guide cones are provided on the opposite sides of the two positioning rods.

[0015] As a preferred embodiment of the present invention, an automatic film winding machine with efficient feeding function, the outer wall of the pressure column is provided with two sliding grooves, and the interior of each of the two sliding grooves is slidably connected to a slider that is fixedly connected to the inner wall of the guide hole.

[0016] The beneficial effects of this utility model are:

[0017] In use, when the lifting plate is moved downward by the drive mechanism, the two positioning rods move downward a certain distance, so that the height of the two positioning rods is equal to that of the unwinding drum of the mother roll. This makes the positions of the two positioning rods and the inside of the unwinding drum of the mother roll correspond. Then, the first drive motor drives the bidirectional lead screw to rotate, which causes the clamping cover and clamping plate to move relative to each other. The two positioning rods enter the inside of the unwinding drum of the mother roll and apply clamping force to the unwinding drum of the mother roll through the clamping cover and clamping plate. Pressure is applied to the pressure sensor through the pressure column. The pressure sensor detects the pressure. When the clamping force of the clamping cover and clamping plate on the unwinding drum of the mother roll reaches the set threshold, the unwinding drum is clamped and fixed. At this time, the pressure sensor transmits the signal to the controller, and the controller controls the first drive motor to stop rotating. Then, the drive mechanism drives the lifting plate to move upward a certain distance, which further raises the fixed mother roll to a certain height. This achieves the purpose of conveniently loading the mother roll, significantly reducing labor intensity and improving loading efficiency.

[0018] During the film winding process, the master roll rotates with the clamping cover and clamping disc, which in turn drives the anti-slip disc to rotate. At this time, the compression spring applies downward pressure to the pressure block, and dynamic friction is generated between the pressure block and the anti-slip disc. This causes the rotation of the shaft, clamping cover and clamping disc to be subject to a certain resistance. During the winding and unwinding process, the roll material can be tightened, thereby effectively avoiding the problem of the roll material becoming loose during the winding process.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0028] Please see Figure 1-6 An automatic film winding machine with efficient feeding function includes a frame 1, a master roll 27 and a winding mechanism. The inside of the frame 1 is slidably connected to a lifting plate 2 through two slide grooves and two sliders. A drive mechanism is provided on the upper side of the lifting plate 2.

[0029] A clamping mechanism is provided on the lower side of the lifting plate 2. The clamping mechanism includes two connecting plates 6 installed at the lower end of the lifting plate 2. A bidirectional lead screw 7 is rotatably connected between the two connecting plates 6. The bidirectional lead screw 7 is driven by a first drive motor 8 installed on the outer wall of the left connecting plate 6. Two translation plates 9 are threadedly connected to the outer wall of the bidirectional lead screw 7. A pressure column 12 is slidably connected through a guide hole 11 on the outer wall of the left translation plate 9. A pressure sensor 14 that abuts against the pressure column 12 is installed on the left side of the left translation plate 9 through a U-shaped frame 13. A clamping cover 15 is rotatably connected to the outer wall of the pressure column 12 through a first bearing 16. A controller 10 is installed at the lower end of the lifting plate 2. A second bearing 18 is fixedly connected through the outer wall of the right translation plate 9. A shaft 19 is fixedly connected to the inner wall of the second bearing 18. A clamping plate 20 is fixedly connected to the left end of the shaft 19. A positioning rod 17 is installed on the side of the clamping plate 20 opposite to the clamping cover 15.

[0030] A tensioning mechanism is provided on the right side of the right translation plate 9. The tensioning mechanism includes an anti-slip disc 21 installed on the right end of the shaft 19. A pressure block 26 is provided on the outer wall of the anti-slip disc 21 to abut against it. A horizontal plate 22 is fixedly connected to the right end of the right translation plate 9. A compression spring 25 is installed between the horizontal plate 22 and the pressure block 26.

[0031] In this embodiment: During use, the lifting plate 2 is driven downward by the drive mechanism, thereby causing the two translation plates 9, the pressure column 12, the clamping cover 15, the shaft 19, the clamping plate 20, and the two positioning rods 17 to move downward by a certain distance. The mother roll 27 is placed on the ground, and an unwinding drum is provided inside the mother roll 27, so that the two positioning rods 17 are at the same height as the unwinding drum. Then, the mother roll 27 rolls on the ground, so that the unwinding drum is positioned between the two positioning rods 17, and the positions of the positioning rods 17 and the inside of the unwinding drum correspond. Then, the first drive motor 8 drives the bidirectional lead screw 7 to rotate, thereby causing the two translation plates 9 to move relative to each other. At the same time, the pressure column 12 and the clamping cover 15 move to the right, and the shaft 19 and the clamping plate 20 move to the left at the same speed, causing the two positioning rods 17 to move relative to each other, so that the two positioning rods 17 can enter the unwinding drum of the mother roll 27. The positioning rod 17 is adapted to the inside of the unwinding drum of the mother roll 27, thereby preventing the mother roll 27 from moving vertically or forward and backward. Subsequently, the clamping cover 15 and the clamping plate 20 apply clamping force to the unwinding drum of the mother roll 27 and apply a leftward pushing force to the pressure column 12. The pressure column 12 applies pressure to the pressure sensor 14, and the pressure sensor 14 detects the magnitude of the pressure. When the clamping force of the clamping cover 15 and the clamping plate 20 on the unwinding drum of the mother roll 27 reaches the set threshold, the unwinding drum is clamped and fixed. At this time, the pressure sensor 14 transmits the signal to the controller 10, and the controller 10 controls the first drive motor 8 to stop rotating. Then, the drive mechanism drives the lifting plate 2 to move upward a certain distance, which can further lift the fixed mother roll 27 to a certain height. In this way, the loading of the mother roll 27 can be completed conveniently, significantly reducing labor intensity and improving loading efficiency.

[0032] The winding mechanism then enables automatic film winding. During the winding process, the first bearing 16 and the second bearing 18 allow the mother roll 27 to rotate with the clamping cover 15 and the clamping disc 20. Simultaneously, the shaft 19 drives the anti-slip disc 21 to rotate. At this time, the compression spring 25 applies downward pressure to the pressure block 26, generating dynamic friction between the pressure block 26 and the anti-slip disc 21. This provides resistance to the rotation of the shaft 19, clamping cover 15, and clamping disc 20, thus tensioning the roll material during winding and unwinding. In this way, the problem of loose roll material during winding is effectively avoided.

[0033] As a technical optimization of this utility model, the winding mechanism includes a flat plate 28 fixedly connected to the front end of the frame 1, a vertical plate 29 installed on the upper end of the flat plate 28, an air shaft 30 rotatably connected to the right end of the vertical plate 29, a winding drum 31 provided on the outer wall of the air shaft 30, and a second drive motor 32 whose output end is fixedly connected to the air shaft 30 installed on the outer wall of the vertical plate 29.

[0034] In this embodiment: the take-up drum 31 is fitted onto the outer wall of the air shaft 30, and air is directly inflated by an air gun aimed at the air nozzle of the air shaft 30. The air bladder of the air shaft 30 expands, and the key bar is pushed out, which can fix the take-up drum 31 to the outer wall of the air shaft 30. Then, the beginning end of the mother roll 27 is pulled out and wrapped around the outer wall of the take-up drum 31. Then, the second drive motor 32 drives the air shaft 30 and the take-up drum 31 to rotate, so that the roll material can be wound onto the outer wall of the take-up drum 31.

[0035] As a technical optimization of this utility model, the driving mechanism includes an internally threaded cylinder 3 fixedly connected to the upper end of the lifting plate 2, a screw 4 extending into the internally threaded cylinder 3 and threadedly connected to the top of the inner wall of the frame 1, and a third drive motor 5 whose output end is fixedly connected to the screw 4 installed at the upper end of the frame 1.

[0036] In this embodiment: the screw 4 is driven to rotate by the third drive motor 5. Since the screw 4 is threadedly connected to the inside of the internal threaded cylinder 3, it can drive the internal threaded cylinder 3 to move and drive the lifting plate 2 to move.

[0037] As a technical optimization of this utility model, a circular hole 23 is provided through the outer wall of the horizontal plate 22, and a retaining rod 24 is installed at the upper end of the pressure block 26, which is sleeved inside the compression spring 25 and passes through the circular hole 23. Two sliding grooves are provided on the outer wall of the retaining rod 24, and a slider that is fixedly connected to the inner wall of the circular hole 23 is slidably connected inside the two sliding grooves.

[0038] In this embodiment, by setting up a retaining rod 24, two sliding grooves and two sliders, the horizontal position of the pressure block 26 can be maintained and the compression spring 25 can be prevented from twisting.

[0039] As a technical optimization of this utility model, the lower end of the lifting plate 2 is provided with a sliding groove, and the upper ends of the two translation plates 9 are each equipped with a slider that is slidably connected inside the sliding groove.

[0040] In this embodiment, a chute and two sliders are provided to improve the stability of the movement of the two translation plates 9.

[0041] As a technical optimization of this utility model, both the first drive motor 8 and the third drive motor 5 are worm gear motors.

[0042] In this embodiment: Since both the first drive motor 8 and the third drive motor 5 are worm gear motors, and worm gear motors have a self-locking characteristic, the output shafts of the first drive motor 8 and the third drive motor 5 can be prevented from rotating in the non-drive state, thereby improving the stability of use.

[0043] As a technical optimization of this utility model, guide cones are provided on the opposite sides of the two positioning rods 17.

[0044] In this embodiment: by setting two guide cones, it is convenient for the two positioning rods 17 to enter the interior of the unwinding drum of the mother roll 27.

[0045] As a technical optimization of this utility model, the outer wall of the pressure column 12 is provided with two sliding grooves, and the inner walls of the two sliding grooves are slidably connected to sliders that are fixedly connected to the inner wall of the guide hole 11.

[0046] In this embodiment, by providing two grooves and two sliders, the pressure column 12 is prevented from rotating inside the guide hole 11.

[0047] The working principle and usage process of this utility model are as follows: In use, the third drive motor 5 first drives the screw 4 to rotate. Since the screw 4 is threaded into the internal threaded cylinder 3, it can move the internal threaded cylinder 3 downwards a certain distance, and also move the lifting plate 2 downwards a certain distance. This causes the two translation plates 9, the pressure column 12, the clamping cover 15, the shaft 19, the clamping plate 20, and the two positioning rods 17 to move downwards a certain distance. The mother roll 27 is placed on the ground, and an unwinding drum is installed inside the mother roll 27, so that the two positioning rods 17 are at the same height as the unwinding drum. The mother roll 27 then rolls on the ground, positioning the unwinding drum between the two positioning rods 17, and aligning the positions of the positioning rods 17 with the inside of the unwinding drum. Then, the first drive motor 8 drives the bidirectional lead screw 7 to rotate, which in turn causes the two translation plates 9 to move relative to each other. Simultaneously, the pressure column 12 and the clamping cover 15 move to the right, and the shaft 19 and the clamping plate 20 move to the left at the same speed, causing the two positioning rods... The relative movement of the two positioning rods 17 allows them to enter the unwinding drum of the mother roll 27. Since the two positioning rods 17 are adapted to the inside of the unwinding drum of the mother roll 27, the vertical and forward / backward movement of the mother roll 27 can be prevented. Subsequently, the clamping cover 15 and the clamping plate 20 apply clamping force to the unwinding drum of the mother roll 27 and apply a leftward pushing force to the pressure column 12. The pressure column 12 applies pressure to the pressure sensor 14, and the pressure sensor 14 detects the magnitude of the pressure. When the clamping force of the clamping cover 15 and the clamping plate 20 on the unwinding drum of the mother roll 27 reaches the set threshold, the unwinding drum is clamped and fixed. At this time, the pressure sensor 14 transmits the signal to the controller 10, and the controller 10 controls the first drive motor 8 to stop rotating. Then, the lifting plate 2 moves upward a certain distance, which can further lift the fixed mother roll 27 to a certain height. In this way, the loading of the mother roll 27 can be completed conveniently, significantly reducing labor intensity and improving loading efficiency.

[0048] Then, the take-up drum 31 is fitted onto the outer wall of the air shaft 30, and air is directly inflated by an air gun aimed at the air nozzle of the air shaft 30. The air bladder of the air shaft 30 expands, and the key bar is pushed out, which can fix the take-up drum 31 to the outer wall of the air shaft 30. Then, the beginning end of the mother roll 27 is pulled out and wound around the outer wall of the take-up drum 31. Then, the second drive motor 32 drives the air shaft 30 and the take-up drum 31 to rotate, thereby winding the roll material to the outer wall of the take-up drum 31. During the film winding process, due to the first bearing 16 and the second bearing 1 The configuration of 8 allows the master roll 27 to rotate with the clamping cover 15 and the clamping plate 20, while the anti-slip plate 21 is rotated via the shaft 19. At this time, the compression spring 25 applies downward pressure to the pressure block 26, and dynamic friction is generated between the pressure block 26 and the anti-slip plate 21. This causes the rotation of the shaft 19, the clamping cover 15 and the clamping plate 20 to be subject to a certain resistance, which can tighten the roll material during the winding and unwinding process. In this way, the problem of the roll material becoming loose during the winding process can be effectively avoided.
