DETAILED DESCRIPTION

[0021] 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. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] A raw silk rack locking device is used in conjunction with a rotary raw silk rack 1. The rotary raw silk rack 1 includes a rotary chassis 11. The rotary chassis 11 is rotatably installed on the workshop floor. The rotary chassis 11 can drive the silk cake above to turn, so that workers can choose a suitable silk cake to feed silk. The bottom surface of the rotary chassis 11 is connected to a locking plate 12. The locking plate 12 is used in conjunction with the raw silk rack locking device to achieve the orientation fixing effect of the rotary raw silk rack 1 and meet the needs of continuous silk feeding operations. The raw silk rack locking device includes a lock base 2 and a lock body 3. The lock body 3 is elastically connected to the lock base 2. The lock body 3 can move vertically up and down. The lock A locking groove 31 is provided on the top of the body 3, and the locking plate 12 rotates with the rotary chassis 11. The lock body 3 is arranged on the movement trajectory of the locking plate 12. The size of the locking groove 31 matches the locking plate 12. When the locking plate 12 moves to the lock body 3 position, the locking plate 12 can be locked into the locking groove 31, forming a locking and fixing effect. At this time, the entire rotary silk rack 1 will not be able to rotate. Only after unlocking can the rotary silk rack 1 resume its rotation function. A plurality of locking plates 12 can be provided, and the plurality of locking plates 12 are evenly distributed on the bottom surface of the rotary chassis 11, and each locking plate 12 corresponds to a silk cake, so that the silk casting and sorting operation is more convenient.

[0023] like Figure 3As shown, a spring 4 is installed between the lock body 3 and the lock base 2, and the lock body 3 and the lock base 2 are elastically connected. The lock base 2 is fixed to the workshop floor, and the lock body 3 can move elastically. The bottom of the lock body 3 is connected to two symmetrically arranged first guide rods 33, and the top surface of the lock base 2 is installed with two rod racks 21. The first guide rods 33 and the rod racks 21 are set one-to-one. The first guide rods 33 are installed through the rod racks 21. The diameter of the through hole on the rod rack 21 matches the diameter of the rod body of the first guide rod 33. The movement guidance of the lock body 3 is achieved through the cooperation of the first guide rod 33 and the rod rack 21, so that the lock body 3 can only move up and down. A slide 32 is provided on the top of the lock body 3. The lock body 3 is moved downwards by the locking plate 31 and the locking plate 12 is locked in the locking groove 31.

[0024] like Figure 3 As shown, the bottom of the first guide rod 33 is connected to a limit plate 34, and the diameter of the limit plate 34 is larger than the through hole on the rod frame 21. The limit plate 34 limits the rising height of the first guide rod 33, so that when the lock body 3 is lifted by the spring 4, the first guide rod 33 will not separate from the rod frame 21.

[0025] Since the locking plate 12 is fixed in position, when unlocking the raw yarn rack locking device, it is only necessary to push the lock body 3 down again. After the lock body 3 is lowered, the locking plate 12 is disengaged from the lock groove 31, and the locking plate 12 can rotate again with the rotary raw yarn rack 1. In order to facilitate the unlocking operation, Figure 2 As shown, a rocker 35 is connected to the side wall of the lock body 3. The installation position of the raw silk rack locking device is close to the ground, so it is more appropriate for workers to use foot unlocking operation. The rocker 35 is designed to facilitate workers to use foot unlocking operation.

[0026] In actual application, it is found that workers need to stand on the spinning trolley when performing high-level spinning and sorting operations. At this time, if the rotation function of the rotary yarn rack 1 is to be unlocked, the worker needs to get off the trolley to operate. After unlocking, the worker needs to get on the trolley again. Moreover, the rotary yarn rack 1 will automatically lock when it rotates. In this way, the worker needs to frequently get on and off, which is very inconvenient. In view of the above situation, Figure 2As shown, the present invention also designs a raw silk rack unlocker, which is used in conjunction with a raw silk rack locking device. The raw silk rack unlocker includes an unlocking drive mechanism 5 and a lifting beam 6. The lifting beam 6 is driven and installed on the unlocking drive mechanism 5. The lifting beam 6 can realize vertical lifting movement by being driven by the unlocking drive mechanism 5. The lower end surface of the lifting beam 6 is connected with a striker 61. The rocker 35 moves up and down with the lifting beam 6. The rocker 35 is set on the descending movement path of the striker 61. After the striker 61 descends, it can hit the force-applying rocker 35, and then the lock body 3 is driven to descend through the rocker 35, thereby realizing the unlocking of the rotation function of the rotary raw silk rack 1.

[0027] like Figure 4 As shown, the unlocking drive mechanism 5 includes a transmission base frame 51, a top beam 52 and a motor 55. The top beam 52 is parallel to the base frame 51. A transmission screw 53 and two second guide rods 54 are installed between the top beam 52 and the base frame 51. The transmission screw 53 is rotatably installed. The two second guide rods 54 are installed on both sides of the transmission screw 53. The two second guide rods 54 are fixedly installed and parallel to the transmission screw 53. The lifting beam 6 is passed through the two second guide rods 54 and is threadedly connected to the transmission screw 53. The output end of the motor 55 is connected to the transmission screw 53. The second guide rod 54 plays a role in limiting the movement of the lifting beam 6. The motor 55 can drive the transmission screw 53 to rotate. When the transmission screw 53 rotates, it can drive the lifting beam 6 to move along the length direction of the second guide rod 54, that is, vertical lifting movement. In order to facilitate workers to operate the raw silk rack unlocker on the silk casting trolley, as shown in FIG. Figure 1 and Figure 2 As shown, the motor 55 of the present invention adopts a remote control motor, and the motor 55 is equipped with a remote control 7. The worker uses the remote control 7 to remotely control the operation of the motor 55 on the thread casting trolley to realize the unlocking control. In the present invention, if the striker 61 is always in the maximum descending state, the lock body 3 is also always in the descending state. At this time, even if the locking plate 12 moves to the lock groove 31 position, it cannot be locked. In this case, it is convenient for the worker to perform the thread casting and sorting operation. After the operation is completed, the striker 61 is remotely controlled to rise. At this time, the raw silk rack locking device can restore the original locking function.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
