Description

Technical Field

[0001] The present application relates to the field of spinning frames, and in particular to an emergency stop protection device for a spinning frame. Background Art

[0002] The spinning frame is a spinning machine that stretches, twists and winds semi-finished roving or slivers into spun yarn during the spinning process. The slivers are stretched and twisted on the roving frame to make roving, the combing machine combs the fibers to make combed slivers, the gill carding machine combines the slivers, and the needle row stretches to improve the sliver structure. The roving is further twisted and spun into spun yarn on the ring spinning frame. The spinning frame is the main machine for spinning.

[0003] During actual operation, the operator may encounter an accident where clothing or hair is caught in the spinning frame. In this case, the spinning frame needs to be stopped immediately. However, the on / off switches of the spinning frame are usually located on both sides of the spinning frame. The operator who encounters an accident cannot access the on / off switches and thus cannot stop the spinning frame immediately, which ultimately leads to damage to personnel or machines. This problem needs to be solved urgently. Utility Model Content

[0030] In order to make the purpose, features, and advantages of the invention of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The embodiment of the present application discloses an emergency stop protection device for a spinning frame, such as Figure 1 and 2 As shown, it includes a frame 1, a support frame 2 is provided on the frame 1, a travel switch 21 is fixedly installed on the support frame 2, and the travel switch 21 is connected to the on-off switch of the spinning frame through an electric wire; a paddle 22 is relatively sliding on the support frame 2, and the paddle 22 can slide to contact the travel switch 21.

[0033] like Figure 1 and 2 As shown, the support frame 2 is provided with a control assembly 3 for controlling the sliding movement of the paddle 22. The control assembly 3 includes a control plate 31, a control rope 32, and an elastic member. The control plate 31 slides on the support frame 2. The cross-section of the control plate 31 is L-shaped, and the paddle 22 and the control plate 31 are fixedly connected. A guide column 311 is fixedly connected to the control plate 31, and a guide sleeve 23 is fixedly connected to the support frame 2. The end of the guide column 311 away from the control plate 31 passes through the guide sleeve 23. The guide sleeve 23 can limit the movement of the guide column 311, thereby limiting the movement of the control plate 31. The frame 1 is fixedly connected to the vertical pole 11. The length of the pole 11 is vertical. One end of the control rope 32 is fixedly connected to the pole 11, and the other end is fixedly connected to the guide column 311. The elastic member is a spring 33, one end of which is fixedly connected to the support frame 2, and the other end is fixedly connected to the control panel 31. Under normal circumstances, the spring 33 applies a thrust to the control panel 31, causing the control panel 31 to move the paddle 22 away from the travel switch 21. When clothing or hair is caught in the spinning frame, the operator can pull the control rope 32, which can move the guide post 311, thereby driving the movement of the control panel 31. The movement of the control panel 31 can drive the paddle 22 to move, causing the paddle 22 to contact the travel switch 21, thereby causing the spinning frame to stop suddenly, reducing the occurrence of accidents.

[0034] like Figure 1 and 3As shown, a support rod 5 is fixedly connected to the frame 1, with the length of the support rod 5 being vertical. The support frame 2 slides on the support rod 5. A positioning assembly 6 is provided on the support rod 5, which includes a positioning plate 61 and a positioning bolt 62. The positioning plate 61 slides on the support rod 5. The positioning plate 61 has a groove for the support rod 5 to be inserted, and the positioning plate 61 can slide until it is in contact with the support frame 2. The positioning bolt 62 passes through the support frame 2 and is threadedly connected to the positioning plate 61. The positioning bolt 62 can be rotated until it abuts the support frame 2. The operator can adjust the height of the support frame 2 according to actual conditions, thereby adjusting the height of the control rope 32. The operator can move the support frame 2 on the support rod 5. When the support frame is moved to a suitable position, the operator moves the positioning plate 61 so that the positioning plate 61 fits the support frame 2, and then screws in the positioning bolt 62 so that the positioning bolt 62 passes through the support frame 2 and the positioning plate 61 and is threadedly connected. The positioning bolt 62 can limit the positioning plate 61 and the support frame 2 to achieve fixation of the two, thereby achieving the installation of the control rope 32.

[0035] like Figure 1 and 4 As shown, the frame 1 is fixedly connected to an auxiliary rod 4, with the auxiliary rod 4 extending vertically. A connecting rod 41 is fixedly connected to the auxiliary rod 4. The connecting rod 41 has a U-shaped cross-section and a rotating block 42 is rotatably connected to the connecting rod 41. The rotating block 42 is positioned below the control rope 32 and has a limiting groove 421 defined therein for the control rope 32 to fit into. The auxiliary rod 4 provides support for the connecting rod 41, which in turn supports the rotating block 42, which in turn supports the control rope 32. The limiting groove 421 further limits the control rope 32, reducing the possibility of deviation and improving its stability.

[0036] The implementation principle of the emergency stop protection device for a spinning frame in the embodiment of the present application is as follows:

[0037] The operator can move the support frame 2 to adjust the height of the control rope 32. When the support frame 2 is moved to the appropriate position, the operator screws in the positioning bolt 62 so that the positioning bolt 62 passes through the support frame 2 and the positioning plate 61 and is threadedly connected. The positioning bolt 62 can limit the positioning plate 61 and the support frame 2, thereby realizing the installation of the support frame 2 and the control rope 32, making it easier for the operator to pull the control rope 32.

[0038] When clothing or hair is caught in the spinning frame, the operator can pull the control rope 32, which can drive the guide column 311 to move, and the movement of the guide column 311 can drive the movement of the control panel 31, and the movement of the control panel 31 can drive the movement of the paddle 22, so that the paddle 22 contacts the travel switch 21, thereby stopping the spinning frame suddenly and reducing the occurrence of accidents.

[0039] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
