Description

Technical Field

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

[0002] The existing winding system for winding film includes a winding device and a feeding device. An empty paper core tube without film rolled up is put on the air shaft and then transported to the winding device, so that the film is rolled up 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 rolled film, puts the empty paper core tube on the air shaft, and then transports it to the winding device for winding the film.

[0003] The existing feeding equipment directly dumps the empty paper core tube onto the receiving platform for sleeve the paper core tube on the outside of the air shaft through the storage rack of the feeding mechanism, which easily causes the paper core tube to be skewed and messy on the receiving platform, thereby reducing the efficiency of conveying the paper core tube and reducing the efficiency of film winding.

[0004] 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

[0005] Based on the above problems, the purpose of the present invention is to provide a feeding device for a winding system which has high stability, high efficiency, can stably place the empty paper core tube on the receiving table and can adjust the air shaft according to the change of the diameter of the paper core tube.

[0006] In view of the above problems, the following technical solutions are provided: a feeding device for a winding system, the feeding device comprising a loading mechanism and a feeding mechanism, the loading mechanism comprising a storage rack and a loading assembly for placing an empty paper core tube on the feeding mechanism, the storage rack is provided with two layers, an upper layer and a lower layer, the upper layer is used to place an empty paper core tube, and the lower layer is used to place a paper core tube with a rolled film, the loading assembly comprises a multi-section cylinder, a first driver for driving the multi-section cylinder to move left and right, and a second driver for driving the multi-section cylinder to move up and down, the multi-section cylinder comprising a cylinder body and a telescopic rod for inserting into the inner hole of the paper core tube; the feeding mechanism comprises a first support frame, a receiving platform provided on the first support frame, and a receiving platform for driving A driving device for displacing the receiving platform toward the storage rack and a supporting device for supporting the inflatable shaft, the supporting device comprising a first supporting assembly, a second supporting assembly and a third supporting assembly, the first supporting assembly comprising a first supporting block and a first transmission member located on the first supporting assembly and used to push the first supporting block to move up and down, the second supporting assembly comprising a second supporting seat located below the supporting platform, a second supporting block arranged 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 comprising a third supporting seat located below the supporting platform, a third supporting block arranged 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.

[0007] In the above structure, when the inflatable 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 inflatable 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 end of the receiving platform away from the storage rack is moved 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 inflatable shafts for supporting the first group of inflatable shafts. The second transmission member drives the second support block to move upward to a to-be-determined position (on the same horizontal plane as the initial position of the first support block). After the receiving platform moves to the position corresponding to the lower layer, the paper core tube with the rolled-up film is pushed onto the lower layer. The second driver drives the multi-section cylinder to rise to the position where the telescopic rod and the inner hole of the empty paper core tube correspond, and the multi-section cylinder controls the telescopic rod to be inserted into the empty paper core tube. After the first driver drives the multi-section cylinder to move toward the outer side of the upper layer to the upper part of the empty paper core tube and the receiving platform where the deflated expansion shaft is located, the second driver controls the multi-section cylinder to move downward until the empty paper core tube is against the receiving platform, and the multi-section cylinder controls the telescopic rod to retract and reset, and the second driver controls the multi-section cylinder to move toward the upper part of the rack to reset. When the upper empty paper core tube is extracted to the receiving platform, 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, and the driving device drives the receiving platform to drive the empty paper core tube to move. When the receiving platform moves away from the end of the receiving platform to the second support assembly, a part of the empty paper core tube has been sleeved on the first group of inflation shafts, and the second transmission member drives the second support block to move downward to reset, and the empty paper core tube is completely sleeved on the first group of inflation shafts. The coordination among the first support assembly, the second support assembly and the third support assembly enables the receiving platform to not stop during the displacement process, thereby improving the working efficiency of the present invention. By setting a third transmission member, the second transmission member can be driven to move upward, so that the second support block can be further moved upward, so that when the diameter of the empty paper core tube increases, the vertical distance of the central axis of the air shaft relative to the receiving platform can be increased to make it compatible with 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 the machine as the diameter of the paper core tube changes, thereby improving the working efficiency and convenience of the present invention. The loading of the paper core tube by the telescopic rod of the multi-section cylinder can be more stable, and the paper core tube will not be placed messily on the receiving platform, thereby improving the reliability of the present invention and the efficiency of loading.

[0008] The present invention is further configured as follows: the first driver includes a fixing frame fixed to one side of the storage rack, a first servo motor arranged on one side of the fixing frame, a first lead screw connected to the first servo motor and fixed on the fixing frame, and a first slider threadedly matched with the first lead screw; the second driver includes a second support frame fixed to the first slider, a second servo motor arranged on one side of the second support frame, a second lead screw connected to the second servo motor and fixed on the second support frame, and a second slider threadedly matched with the second lead screw; a support column is provided on the second slider; the multi-section cylinder is fixed on the support column and is located above the second support frame.

By setting the first lead screw and the second lead screw for transmission, the displacement of the multi-section cylinder is more stable, thereby improving the reliability of the present invention. By setting the first fixing frame, the first lead screw can be easily fixed, and by setting the second supporting frame, the second lead screw can be easily fixed, thereby improving the stability of the first driver and the second driver, and improving the reliability of the present invention.

The driving device drives the receiving platform to drive the paper core tube to be sleeved on the inflatable shaft. After the sleeve is completed, the first cylinder drives the transmission frame to reset, and the claw is lower than the through hole. By setting the claw, the feeding assembly can limit the empty paper core tube when placing it on the claw, so that the empty paper core tube is more stable, and it is convenient to more accurately position the center of the inflatable shaft.

[0037] In the above structure, when the inflatable shaft of the paper core tube with the rolled-up film on the winding device is transported to the receiving platform 212 through the conveying mechanism, the first transmission member 2142 drives the first transmission block to move upward until it is against the inflatable shaft, and the driving device 213 drives the receiving platform 212 to drive the paper core tube with the rolled-up film to move toward the storage rack 221.
