Description
Technical Field
[0001] This application relates to the field of textile machinery, and in particular to an anti-fooling device for the safety protection cover of a loom. Background Art
[0002] The basic characteristics of a shuttleless loom are to separate the weft yarn package from the shuttle, or to carry only a small amount of weft yarn and replace the large and heavy shuttle with a small and light weft inserter, which provides favorable conditions for high-speed weft insertion. Using a shuttleless loom is of great significance for increasing fabric varieties, adjusting fabric structures, reducing fabric defects, improving fabric quality, reducing noise, and improving working conditions. The shuttleless loom has a high speed, usually 4-8 times more efficient than a shuttle loom. During the production process of the loom, the internal mechanical components rotate at high speed, and abnormal situations such as broken needles flying out may occur, posing a great danger to the nearby staff. At the same time, dust, debris, hard sand grains, etc. are easily introduced into the mechanical equipment.
[0003] In the prior art, a protective bracket for textile machinery is provided. During the operation of the textile machine body, it can protect the surrounding personnel and keep a certain safe distance. Moreover, the protective net plate can block some dust, debris, and hard sand grains around the textile machine body to prevent dust, debris, and hard sand grains from entering the interior of the textile machine body and damaging the parts inside the textile machine body.
[0004] However, during the use of this protective net plate, it needs to be opened and closed multiple times according to the usage of the loom. There is no specific sequence between the operator starting the loom and closing the protective net plate. Therefore, the operation of starting the loom first and then closing the protective net plate has a relatively large potential safety hazard and thus needs to be improved. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0027] The following will further describe the present application in detail Figures 1 - 3 with reference to the accompanying drawings.
[0028] The embodiment of the present application discloses an anti-fooling device for the safety protective cover of a loom. Referring to Figure 1 , the anti-fooling device for the safety protective cover of the loom includes a protective cover 1. The protective cover 1 is an acrylic plate made of transparent material. The protective cover 1 is installed on the loom to reduce dust, debris, and hard sand particles from entering the inside of the loom body, and at the same time reduce the safety hazards during the use of the loom.
[0029] A rotating assembly 2 for rotatably connecting with the loom is provided on the protective cover 1, and a control assembly 3 is provided on the rotating assembly 2. The rotating assembly 2 rotates to enable the control assembly 3 to control the start and stop of the loom. Specifically, when the protective cover 1 is rotated and opened through the rotating assembly 2, the control assembly 3 controls the loom to stop; when the protective cover 1 is rotated and closed through the rotating assembly 2, the control assembly 3 controls the loom to start.
[0030] Referring to 1 and Figure 2The rotating assembly 2 includes a rotating frame 21, one end of which is fixed to the loom by bolts. In this embodiment, the rotating frame 21 itself is composed of multiple parts connected by splicing. A connecting notch 211 is provided at one end of the rotating frame 21 away from the loom, and a rotating hole 212 is provided on both side walls of the rotating frame 21. The rotating hole 212 is provided through the connecting notch 211, that is, the rotating hole 212 is connected to the connecting notch 211. A rotating shaft 22 is provided in the connecting notch 211, and both ends of the rotating shaft 22 are inserted in the rotating hole 212, so that the rotating shaft 22 can rotate in the connecting notch 211.
[0031] The rotating shaft 22 is provided with a connecting plate 23 at the connecting notch 211 by bolts, and the end of the connecting plate 23 away from the rotating shaft 22 extends out from the connecting notch 211 and is connected to the protective cover 1 by bolts. The end of the protective cover 1 away from the rotating assembly 2 is provided with a holding notch 11; a limit plate 217 is installed on the rotating frame 21 by bolts, and the limit plate 217 is installed at the bottom of the rotating frame 21, and the end of the limit plate 217 away from the rotating frame 21 extends into the protective cover 1, and the protective cover 1 can be abutted against the limit plate 217.
[0032] When operation is required, the operator extends his hand into the holding notch 11 to open the protective cover 1. When the protective cover 1 rotates, the rotating shaft 22 rotates synchronously. When the rotating shaft 22 rotates, it is linked with the control component 3, so that the control component 3 controls the loom to stop; when the operation is completed, the operator closes the protective cover 1, and the rotating shaft 22 rotates synchronously with the protective cover 1 again. When the inner wall of the protective cover 1 is attached to the top wall of the limit plate 217, the protective cover 1 cannot continue to rotate. At this time, the control component 3 controls the loom to start.
[0033] Reference Figure 2 and Figure 3 The control assembly 3 includes a control pin 31. A control hole 213 is provided at one end of the rotating frame 21 close to the loom. The control hole 213 is communicated with the rotating hole 212. The control pin 31 is inserted into the control hole 213. The control pin 31 can reciprocate along the axial direction of the control hole 213. A clearance notch 221 is provided on the side of the rotating shaft 22 close to the control pin 31. The control pin 31 can abut against the side wall of the rotating shaft 22 located at the clearance notch 221, or against the side wall of the outer edge side wall of the rotating shaft 22, so that the control pin 31 retracts into the control hole 213, or one end of the control pin 31 extends out of the control hole 213.
[0034] A rebound groove 21 is opened on the inner circle side wall of the control hole 213, and a rebound spring 215 is embedded in the rebound groove 21. A rebound ring 311 is integrally formed on the outer peripheral side wall of the control pin 31. One end of the return spring 215 abuts against the inner end wall of the rebound groove 21, and the other end abuts against the rebound ring 311.
[0035] The return spring 215 is located on the side of the rebound ring 311 close to the loom, and a buffer pad 216 is provided on the side of the rebound ring 311 away from the loom. In this embodiment, the buffer pad 216 is made of rubber. The buffer pad 216 is embedded in the inner end wall of the rebound groove 21 and protrudes from the end wall. The buffer pad 216 can be squeezed and deformed.

The controller 33 is electrically connected to the start-stop travel switch 32 and the loom. The controller 33 is used to control the start and stop of the machine.
[0037] When the protective cover 1 is closed, the side wall of the clearance notch 221 at the rotating shaft 22 abuts against the control pin 31, and the end of the control pin 31 away from the rotating shaft 22 retracts into the control hole 213. When the protective cover 1 is opened, the rotating shaft 22 rotates, the position of the clearance notch 221 changes, and finally the outer peripheral side wall of the rotating shaft 22 contacts the control pin 31. The control pin 31 extends from the control hole 213 and contacts the start-stop travel switch 32 to press the button. The start-stop travel switch 32 sends a signal that the button is pressed to the controller 33. After receiving the signal from the start-stop travel switch 32, the controller 33 controls the loom to stop; when the protective cover 1 is closed again, the rotating shaft 22 rotates, the clearance notch 221 is reset again, and the control pin 31 retracts into the control hole 213 under the elastic action of the return spring 215 and abuts against the side wall at the clearance notch 221. The button of the start-stop travel switch 32 is reset, and the start-stop travel switch 32 sends a signal that the button is reset to the controller 33. The controller 33 controls the loom to start.
[0038] The implementation principle of the foolproof device of a safety protective cover for a loom in the embodiment of the present application is as follows: when the protective cover 1 is opened, the control pin 31 extends to press the button of the start-stop travel switch 32, and the start-stop travel switch 32 sends a signal that the button is pressed to the controller 33. After receiving the signal from the start-stop travel switch 32, the controller 33 controls the loom to stop. When the protective cover 1 is closed again, the clearance gap 221 is reset again, and the control pin 31 retracts into the control hole 213 under the elastic action of the return spring 215, and the button of the start-stop travel switch 32 is reset. The start-stop travel switch 32 sends a signal of button reset to the controller 33, and the controller 33 controls the loom to start. Through the cooperation of the start-stop travel switch 32, the rotating shaft 22 and the control pin 31, multi-faceted mechanical linkage is achieved, thereby reducing the safety hazards of the textile machine when it is in use.
[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
