Description

Technical Field

[0001] The invention relates to the technical field of film production equipment, and in particular to a feeding mechanism for feeding equipment. Background Art

[0002] The existing winding system for winding film includes a winding device and a feeding device. After the empty paper core tube without film is sleeved on the air shaft, it is transported to the winding device so that the film is rolled on the paper core tube. After the winding is completed, the conveying mechanism on the winding device transports the air shaft to the feeding device, removes the paper core tube with the film rolled, sleeves the empty paper core tube on the air shaft, and then transports it to the winding device for film winding. The feeding device includes a loading mechanism and a feeding mechanism. The loading mechanism includes a rack and a loading assembly for placing the empty paper core tube on the feeding mechanism. After the loading assembly places the empty paper core tube on the rack on the feeding mechanism, the feeding mechanism cannot fix the empty paper core tube, so it is easy to shake, resulting in the feeding mechanism being unable to stably transport the empty paper core tube, and the feeding mechanism cannot stably sleeve the empty paper core tube on the outside of the air shaft when transporting it, thereby reducing the working efficiency of the feeding device.

[0003] In the existing winding system, when the paper core tube with the rolled film is completely removed from the air shaft, the feeding mechanism needs to be paused, and the air shaft is fixed before the paper core tube can be removed. In addition, the existing feeding mechanism cannot be adjusted according to the change in the diameter of the paper core tube, and thus cannot be adjusted according to customer needs, and cannot be adapted to special work requirements. Summary of the invention

[0004] Based on the above problems, the purpose of the present invention is to provide a feeding mechanism for a feeding device, which has high stability and efficiency in conveying empty paper core tubes, can easily sleeve the empty paper core tubes on the inflatable shaft, and can adjust the inflatable shaft according to changes in the diameter of the paper core tube.

[0005] The cam is an adjustable air bag, and the adjustable air bag is an adjustable air bag that can move with the push of a button. The cam is an adjustable air bag that can move with the push of a button. The cam is an adjustable air bag that can move with the push of a button. The transmission frame is controlled to move up and down relative to the connecting frame. The transmission frame is provided with a claw that is compatible with the through hole, and an arc surface that is compatible with the empty paper core tube is formed between the relative claws. The supporting device includes a first supporting assembly, a second supporting assembly and a third supporting assembly. The first supporting assembly includes a first supporting block and a first transmission member located on the first supporting frame and used to push the first supporting block to move up and down. The second supporting assembly includes a second supporting seat located below the supporting platform, a second supporting block provided on the top of the second supporting seat, a second transmission member for controlling the up and down displacement of the second supporting block, and a third transmission member for controlling the up and down displacement of the second transmission member. The third supporting assembly includes a third supporting seat located below the supporting platform, a third supporting block provided on the top of the second supporting seat, and a fourth transmission member for controlling the up and down displacement of the third supporting block.

[0006] The present invention is further configured such that the support device also includes a fourth support assembly, the fourth support assembly includes a fourth support block and a fifth transmission member for driving the fourth support block to move up and down, the first transmission member and the fourth transmission member are respectively fixed on both sides of the clamping frame, the first support block is located on the side of the clamping frame facing the support platform, the second support seat and the third support seat are fixed to the crossbeam, and the tops of the first support block, the second support block and the third support block are all provided with grooves that are compatible with the inflatable shaft.

[0007] In the above structure, when the air shaft of the paper core tube with the rolled-up film on the winding device is transported to the receiving platform through the conveying mechanism, the first transmission member drives the first transmission block to move upward until it is against the air shaft, and the driving device drives the receiving platform to drive the paper core tube with the rolled-up film to move toward the storage rack. When the receiving platform moves away from the end of the storage rack to leave the third support assembly, the fourth transmission member drives the third support block to move upward until it is against the first group of air shafts for supporting the first group of air shafts, and the second transmission member drives the second support block to move upward to a to-be-determined position (located on the same horizontal plane as the initial position of the first support block), and the receiving platform moves to a position corresponding to the lower layer of the storage rack, and the paper core tube with the rolled-up film is placed on the storage rack. After being mounted on the rack, when the loading assembly places the empty paper core tube on the receiving platform, the first cylinder controls the transmission frame to move upward so that the claws protrude from the through hole. When the loading assembly places the empty paper core tube on the arc surface between the claws, the fourth transmission member controls the third support block to move downward to reset. The first transmission member controls the first support block to move downward to reset. The driving device drives the receiving platform to drive the empty paper core tube to move. When the receiving platform moves away from one end of the storage rack to close to the second support assembly, a part of the empty paper core tube has been sleeved on the first group of air shafts. The second transmission member drives the second support block to move downward to reset. After the empty paper core tube is completely sleeved on the first group of air shafts, the first cylinder drives the transmission frame to reset, and the claws are lower than the through hole. By setting the claws, the empty paper core tube can be limited when the feeding assembly places it on the claws, so that the empty paper core tube is more stable, and the center positioning of the air shaft is more accurate. It can also improve the stability of the receiving platform driving the empty paper core tube to move, and it is convenient to sleeve the empty paper core tube on the air shaft, thereby improving the reliability and stability of the present invention. The cooperation between the first support assembly, the second support assembly and the third support assembly can make the receiving platform not stop during the displacement process, thereby improving the working efficiency of the present invention. By setting the third transmission member, the second transmission member can be driven to move upward, so that the second support block is further moved upward, so that when the diameter of the empty paper core tube increases, the vertical distance of the center axis of the air shaft relative to the receiving platform can be increased, so that it can be adapted to the empty paper core tube, thereby improving the scope of application of the present invention to meet the different needs of different customers, so that the present invention can be switched with one key without stopping according to the different diameters of the paper core tube, thereby improving the working efficiency and convenience of the present invention. The fifth transmission member in the fourth support assembly is linked with the third transmission member in the second support assembly, so that the inflatable shaft can be adjusted more stably as the diameter of the empty paper core tube changes, thereby improving the stability and reliability of the present invention. The provision of the groove can facilitate the first support block, the second support block and the third support block to better match the inflatable shaft, thereby improving the stability of the inflatable shaft and the reliability of the present invention.By setting a clamping block, one end of the inflatable shaft can be limited to prevent the axial displacement of the inflatable shaft caused by the receiving platform moving toward the storage rack, thereby improving the stability of the inflatable shaft, making it easier for the receiving platform to control the paper core tube to be sleeved on the inflatable shaft or removed from the inflatable shaft, thereby improving the reliability of the present invention.

[0008] The present invention is further configured such that an end of the clamping frame away from the receiving platform is provided with a stopper that abuts against the end of the inflatable shaft.

[0009] By adopting the above structure, by setting a stopper, when the receiving platform sleeves the empty paper core tube on the inflatable shaft, one end of the inflatable shaft is limited by the stopper, further preventing axial displacement of the inflatable shaft, improving the stability of the inflatable shaft, and thus improving the reliability of the present invention.

[0010] The present invention is further configured such that the driving device includes a driving motor disposed on the support platform at one side of the clamping frame, a screw connected to the driving motor, and fixing blocks disposed at both ends of the crossbeam for fixing the screw.

[0011] The present invention is further configured such that a transmission block threadably connected to the screw rod is provided at the bottom of the connecting frame, fixing columns are provided on both sides of the transmission block, and a roller abutting against the top surface of the beam is provided on one side of the fixing column.

[0012] In the above structure, the driving motor drives the screw to rotate, the screw cooperates with the transmission block, and the transmission block drives the receiving platform to move. The roller on the fixed column cooperates with the crossbeam to improve the stability of the receiving platform during displacement, and can prevent the screw from driving the transmission block to rotate, thereby improving the reliability of the present invention.

[0013] The present invention is further configured such that a booster is provided at the bottom of the front end of the connecting frame for lifting the storage plate upwards and tilting it downwards toward the storage rack.

[0014] In the above structure, one side of the storage plate is pushed upward by the auxiliary device so that the storage plate is tilted toward the lower plate, and the paper core tube with the rolled film automatically rolls onto the storage rack, thereby reducing manual operation, improving the working efficiency of the present invention, and reducing labor costs.

[0015] The present invention is further configured such that both the driver and the booster are cylinders.

[0016] By adopting the above structure, the stability of the present invention can be improved and the production cost can be reduced.

[0017] Beneficial effects of the present invention: Compared with the existing feeding mechanism, the present invention has high stability and high efficiency in conveying empty paper core tubes and can easily sleeve the empty paper core tube on the air shaft. By setting the clamping claw, the empty paper core tube can be limited when the feeding component places the empty paper core tube on the clamping claw, so that the empty paper core tube is more stable, and the center positioning of the air shaft is more accurate, and the stability of the receiving platform driving the empty paper core tube to move can be improved, which is convenient for sleeve the empty paper core tube on the air shaft, thereby improving the reliability and stability of the present invention.
