Description

Technical Field

[0001] This utility model belongs to the field of winding and splicing technology, specifically relating to a winding and splicing device. Background Technology

[0002] In continuous production and processing fields, such as printing, packaging, textile and film manufacturing industries, the winding process is a key link to ensure continuous and efficient production. During the winding process, when a roll of material is almost used up, a new roll of material must be connected in time to maintain the continuous operation of the production line and avoid the decline in production efficiency and the increase in costs caused by downtime for material replacement.

[0003] Current winding and splicing devices on the market often require the production line to slow down or stop completely before the material roll can be replaced. This not only reduces overall production efficiency but may also cause equipment damage due to sudden start-up and shutdown, increasing maintenance costs. Furthermore, the cutter in existing winding and splicing devices lacks positioning measures during installation, making it difficult to quickly align multiple bolt holes and ensuring proper positioning during installation. This also reduces the ease of disassembly and assembly. Therefore, this utility model proposes a winding and splicing device. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example

[0028] Please see Figures 1 to 7 This is an embodiment of the present utility model, which provides the following technical solution: a winding and splicing device, comprising...

[0029] The receiving frame 1 and the pusher frame 2 are slidably installed on the top of the receiving frame 1, with the front end of the pusher frame 2 extending into the inside of the winding device 4;

[0030] And a drive structure 3 is provided between the pusher frame 2 and the receiving frame 1, for driving the pusher frame 2 to move back and forth, and to enter or exit the winding device 4;

[0031] The inner side of the push frame 2 is rotatably equipped with receiving roller 1 21 and receiving roller 22, and the inner side of the push frame 2 is also provided with receiving roller assembly 5 on the left side relative to receiving roller 22. The inner side of the push frame 2 is provided with cutting mechanism 6 at the top and bottom of receiving roller assembly 5.

[0032] The cutting mechanism 6 includes a cutting shaft 62 rotatably mounted inside the pusher frame 2, an L-shaped cutter holder 63 fixed to the bottom of the cutting shaft 62, and a cutting body 64 mounted on the inner surface of the L-shaped cutter holder 63. The cutting mechanism 6 also includes two cutting cylinders 61 rotatably mounted on the two side surfaces of the pusher frame 2. The free end of the cutting cylinder 61 is hinged to one end of the cutting shaft 62, so that after the cutting cylinder 61 is started, it can push the cutting shaft 62 to rotate, causing the cutting body 64 at the bottom of the cutting shaft 62 to be pushed out or pulled back, thereby realizing the cutting action. In actual use, this device needs to be installed on one side of the winding device 4 on the entire production line. When material needs to be received, the drive structure 3 is activated, pushing the push frame 2 to extend into the inside of the winding device 4. Then, it pre-drives the new shaft that needs to receive material from the outside. At this time, the two receiving cylinders 53 instantly push out the receiving push roller 52, and at the same time, the two cutting cylinders 61 in one of the cutting mechanisms 6 instantly push out the cutting body 64. In this way, the material originally wrapped on the winding device 4 is quickly cut off, and the cut material is made to fit with the receiving push roller 52 and be wrapped by the receiving push roller 52. Finally, it passes around the receiving roller 22 and the receiving roller 1 and is sent out from the bottom of the receiving frame 1 to complete the material receiving.

[0033] In this embodiment, preferably, the receiving roller assembly 5 includes two swing arms 51 rotatably mounted on the inner side of the pusher frame 2 via a rotating shaft, a receiving push roller 52 rotatably mounted between the two swing arms 51 via a rotating shaft, and two receiving cylinders 53 rotatably mounted on the inner walls of both sides of the pusher frame 2. The free end of the receiving cylinder 53 is connected to the swing arms 51, so that the receiving cylinder 53 can push the swing arms 51 to bend when it is running, so that the receiving push roller 52 can be pushed out or pulled back, which is used to push out the receiving push roller 52 when receiving material.

[0034] In this embodiment, preferably, the drive structure 3 includes a drive shaft 32 rotatably mounted on the inner side of the receiving frame 1 via bearings, two racks 31 fixed to the bottom surfaces of both sides of the push frame 2 by bolts, a drive gear 33 mounted on the two end surfaces of the drive shaft 32 and meshing with the racks 31, and a reduction motor 34 mounted on one side surface of the receiving frame 1. The output end of the reduction motor 34 is connected to one end of the drive shaft 32, so that the reduction motor 34 can drive the drive shaft 32 to rotate when it is running. When the drive shaft 32 rotates, the drive gear 33 rotates and drives the racks 31 to move the push frame 2 back and forth, thereby realizing the pushing or pulling action of the push frame 2.

[0035] In this embodiment, preferably, a guide sleeve is fixed to the bottom of both sides of the push frame 2 by bolts, and a guide rail is fixed to the inner wall of both sides of the receiving frame 1 by bolts. The guide sleeve is slidably sleeved on the guide rail to realize the support and smooth sliding of the push frame 2.

[0036] In this embodiment, preferably, a base plate 621 is fixed to both ends of the cutter shaft 62 by bolts, and an L-shaped cutter holder 63 is fixed between the two base plates 621. A side seat plate 622 is also fixed to the inner side of the base plate 621 by bolts, and a positioning structure 65 is provided between the side seat plate 622 and the cutter body 64. It is worth noting that there are two base plates 621 and two side seat plates 622 in a set of cutter mechanisms 6.

[0037] In this embodiment, preferably, the positioning structure 65 includes an L-shaped positioning seat 651 movably mounted on the side of the side seat plate 622, and the L-shaped positioning seat 651 is located on top of the cutter body 64. Since there are two side seat plates 622 in a set of cutter mechanisms 6, there are also two L-shaped positioning seats 651, which are located at both ends of the cutter body 64 respectively. A positioning stop strip 652 is also fixed to the bottom surface of the L-shaped positioning seat 651 relative to one side of the cutter body 64. Hemispherical positioning protrusions 653 are welded and fixed to the top of both ends of the cutter body 64. The bottom surface of the L-shaped positioning seat 651 is provided with a positioning groove 654 corresponding to the hemispherical positioning protrusion 653, so that the cutter body 64... 4. During installation, both ends of the cutter body 64 can be slid into the bottom of the two L-shaped positioning seats 651 and guided by the positioning stop 652 until the cutter body 64 is pushed into the installation position, and the hemispherical positioning protrusion 653 is squeezed into the positioning slot 654. At this time, the cutter body 64 is assisted in positioning, and all the bolts between the cutter body 64 and the L-shaped cutter seat 63 are aligned, which facilitates the subsequent installation and fixing of the cutter body 64 by the operator. It plays an auxiliary positioning role during installation, which can facilitate the quick positioning of the bolt holes and also limit the cutter body 64 to a certain extent during installation, so as to prevent the cutter body 64 from shifting and affecting the installation efficiency.

[0038] In this embodiment, preferably, the side seat plate 622 has an inner groove 655, and a support guide rod 657 is vertically fixed in the inner groove 655. An L-shaped slide block 656 and a spring 658 are slidably sleeved on the surface of the support guide rod 657. The spring 658 is located at the top of the L-shaped slide block 656. A connecting block 659 is fixed on one side surface of the L-shaped slide block 656, and a connecting slide 6221 is provided on the side of the side seat plate 622 for the connecting block 659 to pass through. The end of the connecting block 659 passes through the connecting slide 6221 to the side of the side seat plate 622 and is fixed to the L-shaped positioning seat 651, so that when the bottom of the L-shaped positioning seat 651 is pushed, it can move upward. During installation, the operator first places the cutter body 64 on top of the L-shaped cutter holder 63 and pushes it towards the bottom of the L-shaped positioning seat 651. This allows both ends of the cutter body 64 to be pushed into the two L-shaped positioning seats 651 respectively. During this pushing, the cutter body 64 is guided by the positioning stop 652, ensuring it is horizontally limited and prevents deviation. Simultaneously, when the ends of the cutter body 64 are pushed into the bottom of the L-shaped positioning seat 651, the hemispherical structure of the hemispherical positioning protrusion 653 causes it to press against the bottom surface of the L-shaped positioning seat 651, resulting in an upward force. The force causes the L-shaped positioning seat 651 to be pushed upwards, and the connecting block 659 slides the L-shaped slide 656 upwards, compressing the spring 658 until the hemispherical positioning protrusion 653 is pushed to the bottom of the positioning slot 654. At this time, the spring 658 pushes the L-shaped slide 656 back, and the L-shaped positioning seat 651 rebounds, finally causing the hemispherical positioning protrusion 653 to be engaged in the positioning slot 654, completing the limiting of the cutter body 64. At this time, the multiple bolt holes on the surface of the cutter body 64 are all aligned with the bolt holes on the surface of the L-shaped cutter holder 63, and the cutter body 64 will not undergo horizontal displacement. This allows the operator to easily install the cutter body 64 with bolts, improving the ease of installation. The positioning structure 65 here serves as a guide and auxiliary limit, improving the ease of installation of the cutter body 64 without affecting its normal assembly and disassembly. It facilitates quick alignment of bolt holes during installation. When disassembling the cutter body 64, simply remove all the connecting bolts between the cutter body 64 and the L-shaped cutter seat 63, and then pull the cutter body 64 outward forcefully. This causes the hemispherical positioning protrusion 653 to push the L-shaped positioning seat 651 upward again, ultimately pulling both ends of the cutter body 64 out from the bottom of the two L-shaped positioning seats 651. This completes the disassembly of the cutter body 64, ensuring that the positioning structure 65 does not affect the normal assembly and disassembly of the cutter body 64.

[0039] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
