DETAILED DESCRIPTION

[0013] The specific contents of the utility model are described in detail below with reference to the accompanying drawings and embodiments.

[0014] like Figure 1 and Figure 2As shown, the utility model provides a bobbin loosening machine for embroidery thread production, comprising a support 1, a motor 2 is fixed to one side of the support 1, a connecting plate 3 detachably connected to the rotating shaft of the motor 2 is provided on the other side of the support 1, a barrel shaft 4 is fixed to the side of the connecting plate 3 facing away from the motor 2, a group of openings distributed in a ring array are opened on the outer wall of the barrel shaft 4, a moving bar 41 is slidably connected in the opening, a side of the moving bar 41 close to the axis of the barrel shaft 4 is located in the barrel shaft 4 and is inclined, a ring 32 is fixed on the connecting plate 3, and a spring 42 connected to the inner wall of the ring 32 is fixed to the side of the moving bar 41 away from the axis of the barrel shaft 4; an electric telescopic rod 7 is fixed to the end of the barrel shaft 4 away from the connecting plate 3, and a disc 71 located between a group of moving bars 41 is fixed to the telescopic end of the electric telescopic rod 7.

[0015] like Figure 1 , Figure 2 and Figure 3 As shown, a round block 21 is fixed on the rotating shaft of the motor 2, and a groove 22 is provided on the side of the round block 21 away from the motor 2, and a group of slots 23 are provided on the inner wall of the slot 22; a plug-in plate 31 inserted into the groove 22 is fixed on the side of the connecting plate 3 away from the cylindrical shaft 4, and a group of limit blocks are fixed on the plug-in plate 31, and a group of limit blocks are respectively located in a group of slots 23, and the round block 21 is fixed to the plug-in plate 31 by bolts. After the plug-in plate 31 is inserted into the groove 22, the limit blocks are inserted into the slots 23 (the limit blocks are not shown in the figure), and after the plug-in plate 31 and the round block 21 are docked, the round block 21 and the plug-in plate 31 are fixed together with bolts; after the cylindrical shaft 4 has been used for a long time, the staff can disassemble the plug-in plate 31 and the round block 21, and then inspect, maintain or replace the parts in the cylindrical shaft 4.

[0016] like Figure 1 and Figure 2 As shown, a limit rod 43 penetrating the collar 32 is fixed on the moving bar 41, and the limit rod 43 is located on the inner side of the spring 42. A scale 33 in contact with a limit rod 43 is fixed on the collar 32. After the loose tube is sleeved on the cylinder shaft 4, the staff can judge the distance that the moving bar 41 needs to move according to the inner diameter of the loose tube. When the moving bar 41 moves, the spring 42 is compressed, and the limit rod 43 moves with it. The staff observes the moving distance of the limit rod 43 by checking the scale 33. When the limit rod 43 moves to the specified position, the staff can close the electric telescopic rod 7 in time; and the limit rod 43 can also increase the stability of the moving bar 41 when it moves, and can also limit the spring 42.
