Description

Technical Field

[0001] This utility model relates to the field of fabric rolling machine technology, specifically to an automatic material feeding mechanism for fabric rolling machines. Background Technology

[0002] Fabric rolling machines are widely used in the clothing, textile, leather, and plastic industries for cutting various raw materials such as cotton, linen, synthetic leather, silk, and knitwear. In the traditional fabric rolling machine's take-up roller unloading operation, the take-up roller needs to be replaced manually after the roll-up is completed. The specific operation process includes: after stopping the machine, removing the full roll roller, then manually installing the empty roller and re-threading the fabric.

[0003] However, in the existing technology, the rollers are mostly fixed to the drive shaft by bolt connection. This connection method requires tools for disassembly, replacement and installation, and the operation steps are cumbersome. At the same time, the rollers are heavy after winding, and the transfer efficiency after disassembly is low and there are operational risks. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic material feeding mechanism for a fabric rolling machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic unloading mechanism for a fabric rolling machine, comprising a base plate, mounting plates symmetrically arranged on the base plate, a drive shaft arranged on the mounting plate, a rotating rod arranged on the drive shaft through the mounting mechanism, a take-up roller arranged outside the rotating rod, a lifting assembly arranged on the base plate through a moving component, and an ejection assembly matching the mounting mechanism arranged on the side wall of the lifting assembly.

[0006] Preferably, in order to facilitate installation and splicing, as well as subsequent disassembly and replacement, the installation mechanism includes plug-in blocks set on the end faces of the two drive shafts close to each other, and plug-in slots are opened at both ends of the rotating rod to be plugged into the plug-in blocks.

[0007] Preferably, in order to limit and fix the device after installation without affecting the winding and use, and to facilitate subsequent disassembly, a sliding cavity is provided inside the plug block. A movable plate is symmetrically slidably arranged inside the sliding cavity by means of a spring. Each end of the movable plate that is far apart from each other is provided with a limit member. The limit member slides out of the sliding cavity. A limit hole matching the limit member is provided on the side wall of the plug groove at the end of the rotating rod.

[0008] Preferably, in order to facilitate the movement of the lifting assembly and the disassembly and movement of the take-up roller, the moving assembly includes a linear guide rail device mounted on the base plate, a guide rail slider mounted on the linear guide rail device, and a first electric push rod mounted on the guide rail slider, the first electric push rod being connected to the lifting assembly.

[0009] Preferably, in order to facilitate the lifting of the take-up roller, facilitate the installation and disassembly of the conveyor, and ensure stability and firmness, the lifting assembly includes a support plate connected to the output end of the first electric push rod. The support plate has a groove, and an anti-slip pad is provided on the inner arc surface of the groove. The groove engages with the end of the rotating rod.

[0010] Preferably, in order to facilitate the ejection of the limiting member from the limiting hole, thereby losing its limiting fixation and facilitating disassembly, the ejection assembly includes a fixing plate disposed on the end face of the support plate near the mounting plate, a second electric push rod disposed on the fixing plate, and a top plate disposed at the output end of the second electric push rod, the top plate being matched with the limiting member.

[0011] Preferably, in order to prevent slippage, a rubber pad is provided on the side wall of the top plate, and the diameter of the top plate is smaller than the inner diameter of the limiting hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) The entire process of taking-up roller replacement is automated through structural optimization. The installation mechanism adopts a quick-connect design of plug-in block and plug-in slot, combined with the automatic locking function of spring-driven limit component and limit hole. While ensuring the stable fixation of the taking-up roller, the limit component can be quickly unlocked by pushing the top plate with the second electric push rod of the ejector component, avoiding the problems of tool dependence and cumbersome operation in the traditional bolt connection method; (2) The moving component works in coordination with the linear guide rail device and the first electric push rod to make the lifting component move precisely to the bottom of the rotating rod. The groove and the anti-slip pad are engaged to achieve stable lifting of the winding roller. With the horizontal movement capability of the linear guide rail, the winding roller is automatically transferred from the drive shaft to the lifting component. The linkage design of the ejection component and the lifting component ensures that the limiting component is reliably ejected during disassembly through the cooperation of the top plate and the rubber pad. During assembly, the spring potential energy is used to realize the automatic reset and locking of the limiting component, forming a complete automated material unloading closed loop.

[0015] 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.

[0016] Please see Figures 1-4 This utility model provides an embodiment of an automatic material feeding mechanism for a fabric rolling machine, comprising a base plate 11, on which mounting plates 12 are symmetrically arranged, and a drive shaft 14 is mounted on the mounting plates 12. The drive shaft 14 is connected to a drive device, which mainly consists of a motor, a gearbox, and a coupling, etc., to facilitate the rotation of the drive shaft 14 and the take-up roller 13 outside the rotating rod 15, thus facilitating the winding of the fabric. This is a relatively mature technology and will not be described in detail here. The drive shaft 14 is mounted with the rotating rod 15 through the mounting mechanism, and the take-up roller 13 is mounted outside the rotating rod 15. To facilitate the installation and disassembly of the take-up roller 13 and the automatic material feeding of the take-up roller 13 on the fabric rolling machine, the mounting mechanism includes an insertion joint located at the end faces of the two drive shafts 14 close to each other. The two ends of the connecting rod 15 are provided with insertion slots 46 for insertion into the connecting block 41. The initial positioning and fixing are achieved by inserting the connecting block 41 and the insertion slots 46. The connecting block 41 has a sliding cavity 44 inside. The sliding cavity 44 is symmetrically arranged with a moving plate 43 through a spring 45. Each end of the moving plate 43 is provided with a limit member 42. The limit member 42 is composed of a column and a hemisphere, which facilitates insertion and limit and ensures a stable and firm connection. The limit member 42 slides out of the sliding cavity 44. The end of the connecting rod 15 is provided with a limit hole 47 on the side wall of the insertion slot 46 that matches the limit member 42. The base plate 11 is provided with a lifting component through the moving component. The side wall of the lifting component is provided with an ejection component that matches the installation mechanism.

[0017] Please see Figures 1-4To facilitate automatic unloading and disassembly and transportation of the take-up roller 13, the moving component includes a linear guide rail device 21 mounted on the base plate 11. The linear guide rail device 21 is only partially shown in the figure. A guide rail slider 22 is mounted on the linear guide rail device 21. The linear guide rail device 21 and guide rail slider 22 can be driven by a linear motor to achieve reciprocating movement of the guide rail slider 22 on the linear guide rail device 21. Other methods, such as reciprocating guide rails, can also be used; these are mature technologies and will not be elaborated upon here. A first electric push rod 23 is mounted on the guide rail slider 22. The first electric push rod 23 is connected to a lifting component. The lifting component includes a support plate 31 connected to the output end of the first electric push rod 23. The support plate 31... A groove is provided, and an anti-slip pad 32 is provided on the inner arc surface of the groove. The groove engages with the end of the rotating rod 15, which facilitates engagement of the end of the rotating rod 15 during disassembly and transportation. This allows the moving assembly to move and transport the rotating rod 15 and the winding roller 13 as a whole. The ejector assembly includes a fixing plate 33 located on the end face of the support plate 31 near the mounting plate 12. A second electric push rod 34 is provided on the fixing plate 33. A top plate 35 is provided at the output end of the second electric push rod 34. The top plate 35 matches the limiting member 42. A rubber pad 36 is provided on the side wall of the top plate 35. The diameter of the top plate 35 is smaller than the inner diameter of the limiting hole 47, which facilitates the ejection of the limiting member 42 from the limiting hole 47 during disassembly, thus eliminating the limiting fixation between the plug-in block 41 and the plug-in groove 46 and facilitating disassembly.

[0018] Working Principle: When the take-up roller 13 needs to be disassembled during use, the linear guide rail device 21 moves the guide rail slider 22 as a whole, moving the support plate 31 directly below the rotating rod 15. The first electric push rod 23 extends, moving the support plate 31 upwards, and the rotating rod 15 enters the groove, where it engages with the anti-slip pad 32 for initial locking. Then, the top plate 35 aligns with the limiting member 42, and the second electric push rod 34 extends, bringing the top plate 35 closer together to the limiting member 42. Continuing to move, it exerts pressure on the limiting member 42. The rubber pad 36 prevents slippage. At this point, the two limiting members 42 approach each other, and the moving plate 43 slides within the sliding cavity 44. The spring 45 contracts, storing potential energy, and the limiting member 42 leaves the limiting hole 47, losing its limiting and fixing effect on the insertion block 41 and the insertion groove 46. Then, the first electric push rod 23 retracts, moving the support plate 31 downwards, and the take-up roller 13... Under the influence of gravity, as the roller moves downward, the insertion block 41 separates from the insertion slot 46, completing the disassembly. Then, the linear guide device 21 operates, moving the guide slider 22 as a whole to automatically unload the take-up roller 13. When assembly is required, the new take-up roller 13 is placed into the groove of the tray 31. The linear guide device 21 operates, moving the guide slider 22 to directly below the drive shaft 14. The first electric push rod 23 extends, moving the whole upward. Then, the limiting member 42 is pressed, and the roller continues to move upward. The insertion block 41 is inserted into the insertion slot 46, and the limiting member 42 aligns with the limiting hole 47. Under the potential energy of the spring 45, the limiting member 42 resets and enters the limiting hole 47 for limiting and fixing, completing the assembly. The first electric push rod 23 retracts, moving the tray 31 downward to reset. Then, the linear guide device 21 operates, moving the guide slider 22 and the tray 31 to reset for future use.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
