Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of thin film production equipment, and particularly relates to a core extraction assisting mechanism for film rolls. Background Art
[0002] After the thin film is produced, it is usually wound into a film roll by using a paper core tube sleeved on a winding shaft, and the paper core tube is sleeved on the winding shaft, and the winding shaft is also called a core shaft. After the film roll winding is completed, it is necessary to extract the core shaft from the inside of the paper core tube, and this process is called core extraction. In the prior art, the core extraction process of most thin film production equipment is carried out by manual labor of workers. However, since the core shaft is an iron shaft and generally about 2 to 3 meters in length, it is very heavy. Therefore, it is very laborious for workers to extract the core by relying solely on manpower. In addition, multiple people are required to cooperate, which is strenuous and time-consuming. Content of the Utility Model
[0003] The purpose of the utility model is to overcome the above-mentioned drawbacks and provide a core extraction assisting mechanism for film rolls, which can make the core extraction process labor-saving and save labor.
[0004] Its purpose can be achieved according to the following scheme: A core extraction assisting mechanism for film rolls includes a fixed base, a first-level support is horizontally rotatably installed above the fixed base, a second-level support is vertically movably installed on the first-level support, and a second-level support driving mechanism for driving the vertical movement of the second-level support is also installed on the first-level support; the second-level support is connected with a first horizontal swing arm by a first vertical hinge shaft, the swing end of the first horizontal swing arm is connected with a second horizontal swing arm by a second vertical hinge shaft, the end of the second horizontal swing arm is connected with a third-level support by a third vertical hinge shaft, the third-level support is provided with a notch for accommodating the end of the winding shaft, and the orientation of the notch is horizontal; a vertically movable clamping block is also arranged in the third-level support, the clamping block is located above the notch, and a vertical air cylinder for driving the vertical movement of the clamping block is also installed in the third-level support.
[0005] The part of the third-level support located below the notch is called the lower flank of the notch, and the lower flank of the notch is in a V shape with a lower middle and higher sides.
[0006] The second-level support driving mechanism includes a motor, a gear, and a vertical rack. The vertical rack is fixed on the first-level support, the gear is driven by the motor, the gear and the motor are installed on the second-level support and move vertically synchronously with the second-level support, and the gear meshes with the vertical rack.
[0007] The utility model has the following advantages and effects:
[0008] During the core extraction process, the end of the mandrel can be placed into the notch of the third-level support, and the end of the mandrel can be clamped by the cooperation of the clamping block and the lower flank of the notch. In this way, during the core extraction process before the mandrel is completely separated from the film roll, the weight of the end of the mandrel will be fully borne by the third-level support, and the worker does not need to bear the weight of the mandrel. The worker only needs to provide the horizontal force required for core extraction, and the horizontal force required for core extraction is much smaller than the weight of the mandrel. Therefore, the core extraction process is easy and labor-saving, and there is no need for multiple people to cooperate, which saves both labor and manpower. Brief Description of the Drawings

[0017] Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5A core-pulling mechanism assisted by a film roll, as shown, includes a fixed base 6. Above the fixed base 6, a first-stage support 1 is installed. Between the first-stage support 1 and the fixed base 6, there is a bearing 60, so that the first-stage support 1 can rotate horizontally relative to the fixed base 6. The first-stage support 1 is provided with a vertical guide rail 11. On the vertical guide rail 11, a second-stage support 2 is vertically movably installed. On the first-stage support 1, there is also installed a second-stage support driving mechanism for driving the vertical movement of the second-stage support 2. The second-stage support driving mechanism includes a motor 21, a gear 22, and a vertical rack 23. Among them, the vertical rack 23 is fixed on the first-stage support 1. The gear 22 is driven by the motor 21. The gear 22 and the motor 21 are installed on the second-stage support 2 and move vertically synchronously with the second-stage support 2. The gear 22 meshes with the vertical rack 23. The second-stage support 2 is connected to a first horizontal swing arm 51 by a first vertical hinge shaft 10. The swing end of the first horizontal swing arm 51 is connected to a second horizontal swing arm 52 by a second vertical hinge shaft 20. The end of the second horizontal swing arm 52 is connected to a third-stage support 3 by a third vertical hinge shaft 30. The third-stage support 3 is provided with a notch 32 for accommodating the end of the winding shaft. The orientation of the notch 32 is horizontal. In the third-stage support 3, there is also a vertically movable clamp 4. The clamp 4 is located above the notch 32. In the third-stage support, there is also installed a vertical cylinder 41 for driving the vertical movement of the clamp 4. The part of the third-stage support below the notch 32 is called the lower flank 31 of the notch. The lower flank 31 of the notch is V-shaped with a low middle (i.e., Figure 3 point D in it is the low point) and high sides.
[0018] The usage process of the above embodiment is as follows:
[0019] When core-pulling is required, drag the third-stage support 3 horizontally to reach near the end of the winding shaft 8. The motor 21 is started to drive the gear 22 to rotate. The gear 22 rolls along the vertical rack 23, driving the third-stage support 3 (including the vertical cylinder 41 and the clamp 4) to move vertically. When the vertical position of the notch 32 is aligned with the end of the winding shaft 8, the motor 21 stops rotating. Then continue to drag the third-stage support 3 horizontally to make the end of the winding shaft 8 enter the notch 32, as Figure 6 shown. Then the vertical cylinder 41 drives the clamp 4 to move downward. The clamp 4 and the lower flank 31 of the notch clamp the winding shaft 8, as Figure 7 shown. Then, pull out the winding shaft 8 from the paper core tube along the axial direction of the winding shaft 8, as Figure 8As shown, during this process, the worker only needs to provide a horizontal force and does not need to bear the weight of the rewinding shaft 8. During this process, the third-level support 3 can rotate passively horizontally around the third vertical hinge axis 30, the second horizontal swing arm 52 can rotate passively horizontally around the second vertical hinge axis 20, the first horizontal swing arm 51 can rotate passively around the first vertical hinge axis 10, and the first-level support 1 can rotate passively horizontally around the bearing 60. After the rewinding shaft 8 completely withdraws the paper core tube, the worker holds one end of the rewinding shaft 8 and drags the rewinding shaft 8 to move horizontally, so that the rewinding shaft 8 comes above the rewinding shaft transfer platform 81. Then the motor 21 starts and drives the gear 22 to rotate. The gear 22 rolls along the vertical rack 23, driving the third-level support 3 (including the vertical cylinder 41 and the clamping block 4) to move downward until the rewinding shaft 8 is transferred to the rewinding shaft transfer platform 81, completing the core pulling step. The above process can be carried out by only one person.
