Description

Technical Field

[0001] The utility model relates to the field of packaging bag production and winding devices, in particular to a coiled material winding device for packaging bag production. Background Art

[0002] Packaging bags refer to bags used to package various items, which make it easy to transport goods during the production and circulation process, prevent goods from being damaged by moisture, and are easy to store. At the same time, compared with other containers, packaging bags take up less space, are light in weight, and are easy to carry. Therefore, they are widely used in daily life and industrial life. In real life, during the production process of packaging bags, the packaging bags will be rolled up by a coil winding device.

[0003] The cam is fixedly mounted on the support frame, and the cam is fixedly mounted on the support frame, and the cam is fixedly mounted on the support frame.

[0004] However, the above device still has certain shortcomings, mainly reflected in the lack of a clamping mechanism. This lack directly leads to the inability to effectively compress the packaging bag material during high-speed or long-term winding processes. The bag material is prone to loosening or even falling off due to external factors or uneven internal tension. This will not only increase the difficulty of subsequent processing steps, such as reorganizing or repairing fallen packaging bags, but will also significantly reduce the overall operating efficiency and winding quality of the winding device, thereby affecting the stability of the production line and the final quality of the product.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] The following describes an embodiment of the present invention based on its overall structure.

[0030] A coil winding device for producing packaging bags, such as Figure 1 - Figure 5 As shown, it includes a device body 1, a motor 2 and a spring 7. A top plate 3 is slidably installed in the device body 1, and a first slider 303 is fixedly installed on the outer wall of the top plate 3. A first slide groove 102 corresponding to the first slider 303 is opened in the device body 1. When the top plate 3 slides, the first slider 303 slides in the first slide groove 102. A second slider 304 is fixedly installed on the outer wall of the top plate 3, and a threaded rod 4 is connected to the inner thread of the second slider 304. The threaded rod 4 rotates, and then the second slider 304 slides up and down through the thread. A second slide groove 103 corresponding to the second slider 304 and the threaded rod 4 is opened in the device body 1. The threaded rod 4 is installed in the second slide groove 103, and the second slider 304 is in the second slide groove 103. The device body 1 slides in the slide groove 103, and a connecting rod 6 is rotatably installed at the bottom of the device body 1, and a bevel gear 5 is fixedly installed on the outer wall of the connecting rod 6, and a bevel gear 5 is also installed at the end of the threaded rod 4. Through the mutual engagement of the bevel gears 5, when the connecting rod 6 rotates, the horizontal rotation force is converted into a vertical rotation force through the bevel gear 5, thereby rotating the threaded rod 4, and a first roller 101 is rotatably installed in the device body 1, and a second roller 301 corresponding to the first roller 101 is rotatably installed at the bottom of the top plate 3. The first roller 101 and the second roller 301 are fitted together to press the packaging bag, and the bottom of the top plate 3 is also rotatably installed with a third roller 302, and the end of the packaging bag is fixed by the third roller 302 and the winding roller in the device body 1.

[0031] See also Figure 3 and Figure 4 There are multiple groups of first sliders 303 symmetrically installed on the outer walls of both sides of the top plate 3, and each group of first sliders 303 consists of two symmetrical first sliders 303, and the maximum distance between the two symmetrical first sliders 303 corresponds to the width of the top plate 3. The first sliders 303 on both sides slide in the first slide groove 102, so that the position of the top plate 3 can be adjusted, and the sliding force is relatively symmetrical.

[0032] See also Figure 5 A spring 7 is installed in the first slide groove 102, and one end of the spring 7 is fixedly connected to the outer wall of the first slide groove 102, and the other end of the spring 7 is fixedly connected to the first slider 303. The spring 7 will continuously apply pressure to the first slider 303, so that the first slider 303 drives the top plate 3, thereby making the fixing effect of the second roller 301 and the third roller 302 better.

[0033] See also Figure 3 and Figure 4 There are multiple groups of second sliders 304 symmetrically installed on the outer walls on both sides of the top plate 3, and the shape of the second slide groove 103 corresponds to the second slider 304, and the length of the second slide groove 103 corresponds to the threaded rod 4. The second slider 304 slides in the second slide groove 103, and the threaded rod 4 is installed in the second slide groove 103, so that the second slider 304 can be pushed into the second slide groove 103 by the threaded rod 4.

[0034] See also Figure 1 、 Figure 3 and Figure 4 There are multiple groups of bevel gears 5 symmetrically installed on the connecting rod 6, and the installation positions of the multiple groups of bevel gears 5 correspond to the multiple groups of second sliders 304, and the multiple groups of bevel gears 5 on the connecting rod 6 are all engaged with the bevel gears 5 at the bottom of the corresponding threaded rod 4. When the connecting rod 6 rotates, the bevel gears 5 on the connecting rod 6 are driven to rotate, and then the connecting rod 6 can be driven to rotate through the bevel gears 5.

[0035] See also Figure 1 The second roller 301 is installed above the first roller 101, and the third roller 302 is installed above the winding roller in the device body 1. When the top plate 3 moves downward, the second roller 301 is better fitted with the first roller 101, and the third roller 302 is better fitted with the winding roller in the device body 1, thereby achieving a clamping and fixing effect.

[0036] See also Figure 1 and Figure 4 One end of the connecting rod 6 passes through the device body 1, and a rotating handle is installed at the end of the connecting rod 6 passing through the device body 1. The connecting rod 6 is rotated by rotating the rotating handle, making the connecting rod 6 more convenient to rotate.

[0037] The working principle of the present invention is as follows: when winding is required, the connecting rod 6 is first rotated to rotate the bevel gear 5 on the connecting rod 6, and the bevel gear 5 at the bottom of the threaded rod 4 drives the threaded rod 4 to rotate, and then the threaded rod 4 drives the top plate 3 to slide through the second slider 304. The top plate 3 first moves upward and drives the second roller 301 and the third roller 302 at the bottom to move upward, so that a gap is generated between the second roller 301 and the first roller 101, and a gap is generated between the third roller 302 and the winding roller in the device body 1, and the end of the packaging bag is placed between the third roller 302 and the device body 1, and the subsequent part of the packaging bag is placed between the second roller 301 and the first roller The rollers 101 are interposed between them, and the connecting rod 6 is rotated in the opposite direction to move the top plate 3 downward, and the third roller 302 and the winding roller are pressed against the end of the packaging bag, and the second roller 301 and the first roller 101 are pressed against the subsequent part of the packaging bag, and the top plate 3 slides in the first slide groove 102 of the device body 1. The outer wall of the first slider 303 is connected to the spring 7, and the spring 7 further increases the pressing force of the third roller 302 and the second roller 301. The power is turned on, the motor 2 is started, the winding roller starts to rotate and rewind, and drives the third roller 302 to rotate. The subsequent part of the packaging bag will be smoothed in advance by the second roller 301 and the first roller 101 to facilitate the subsequent rewinding of the rewinding roller.
