Technical Field
[0001] The utility model belongs to the technical field related to trouser waist machines, in particular to a bending needle mechanism and a trouser waist machine. Background Art
[0002] Currently, most trouser waist machines on the market are multi-needle machines. In order to meet the needs of trouser waists of different specifications and to switch quickly, the machine will be pre-installed with multiple needle positions on the looper seat when it is shipped. However, due to limited space, there are often other parts blocking the direction close to people. Therefore, it is extremely difficult to thread the looper during use, especially when the needle position is small and the distance between two adjacent loopers is smaller. In this way, threading takes a lot of time, which greatly reduces the sewing efficiency. Utility Model Content

[0017] In one of the embodiments, the driving assembly further includes an elastic member, which is sleeved on the bending needle shaft and abuts against the bending needle swing seat, and the elastic member can push the bending needle swing seat to move toward the limit block.
[0018] It can be understood that the elastic deformation of the elastic member is used to drive the bending needle swing seat toward the limit block, so that the drive component can simplify the structure of the drive component while meeting the requirements for the reciprocating motion of the bending needle swing seat on the bending needle shaft.
[0019] In one of the embodiments, a retaining ring is fixedly connected to the bending needle shaft, and an end of the elastic member away from the bending needle swing seat abuts against the retaining ring.
[0020] In one embodiment, the push plate is capable of pushing the bending needle assembly in a surface-to-surface contact manner.
[0021] It can be understood that the push plate pushes the bending needle assembly in a face-to-face contact manner, which can increase the contact area between the two when the push plate pushes the bending needle assembly, thereby improving the stability of the push plate when driving the bending needle swing seat to move away from the limit block.
[0022] In one embodiment, the needle bending mechanism further comprises a mounting seat, and the body of the telescopic driving member is fixedly connected to the mounting seat;
[0023] Wherein, the mounting seat is used for fixed connection with the casing.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0037] like Figure 1As shown, the bending needle mechanism 100 provided in one embodiment of the present application includes a bending needle assembly 10, a bending needle shaft 20, a clutch assembly 30 and a driving assembly 40, wherein the clutch assembly 30 includes a limit block 31 and a bending needle swing seat 32, wherein the limit block 31 is fixedly connected to the bending needle shaft 20, and the bending needle swing seat 32 is rotatably mounted on the bending needle shaft 20 and connected to the bending needle assembly 10; the driving assembly 40 is transmission-connected to the bending needle swing seat 32, and the driving assembly 40 can drive the bending needle swing seat 32 to reciprocate on the bending needle shaft 20 to control the locking / unlocking between the bending needle swing seat 32 and the limit block 31; when the bending needle swing seat 32 is locked with the limit block 31, the bending needle swing seat 32 and the limit block 31 are circumferentially limited. Here, the locking between the bending needle swing seat 32 and the limit block 31 specifically refers to the locking of the bending needle swing seat 32 and the limit block 31 in the circumferential direction. It should be noted that the specific structure of the bending needle assembly 10 can adopt the conventional structure of the existing trouser waist machine, which will not be elaborated here.
[0038] As can be seen from the above, when the operator needs to thread the bending needle assembly 10 of the bending needle mechanism 100, the driving assembly 40 can be used to push the bending needle assembly 10 out, and the bending needle swing seat 32 can be separated from the limit block 31, so that the bending needle assembly 10 can be rotated on the bending needle shaft 20 through the bending needle swing seat 32; thereafter, the operator holds the bending needle assembly 10 by hand and rotates the bending needle assembly 10 towards the operator, which can provide a larger operating space for the subsequent threading of the bending needle assembly 10, and during the threading process, the visibility is higher, thereby facilitating the threading of the bending needle assembly 10.
[0039] like Figure 1 As shown, the limit block 31 is mounted on the bending needle shaft 20, and then the limit block 31 is locked by the first fixing screw 101, and the limit block 31 is fixedly connected to the bending needle shaft 20. Of course, in other embodiments, the limit block 31 can also be assembled to the bending needle shaft 20 by welding or interference fit.
[0040] like Figure 2As shown, the clutch assembly 30 also includes a connecting pin 33, which is fixedly connected to the looper swing seat 32, and the connecting pin 33 can be plugged and matched with the limit block 31 under the drive of the looper swing seat 32, and the looper swing seat 32 is locked with the limit block 31. In other words, the looper swing seat 32 can be locked with the limit block 31 by plugging and matching between the connecting pin 33 fixed to the looper swing seat 32 and the limit block 31, so that on the basis of satisfying the locking of the looper swing seat 32 on the limit block 31, it has the effect of simplifying the structure of the clutch assembly 30. Here, the connecting pin 33 is partially inserted into the looper swing seat 32, and the part of the connecting pin 33 inserted into the looper swing seat 32 is locked by the second fixing screw 102. Of course, in other embodiments, the connecting pin 33 can also be connected to the looper swing seat 32 in an interference fit manner, or the connecting pin 33 and the looper swing seat 32 are directly connected as one.
[0041] like Figure 2 As shown, the connecting pin 33 has a plug connector 331, and the limiting block 31 is provided with a slot 311 matching the plug connector 331, and the plug connector 331 can be plugged and matched with the slot 311; wherein the plug connector 331 can abut against the groove wall 3111 of the slot 311, so as to limit the plug connector 331 circumferentially to the limiting block 31. Here, the cross section of the plug connector 331 is square.

In other words, the drive assembly 40 can use the telescopic drive member 41 to realize the control of the movement of the bending needle swing seat 32 to separate from the limit block 31, so that the movement control of the bending needle swing seat 32 to separate from the limit block 31 can be automated, and it is further convenient for subsequent operators to thread the bending needle assembly 10. Here, the telescopic drive member 41 is configured as a cylinder, a telescopic motor, etc.
[0043] As preferably, Figure 1 As shown, the push plate 42 can push the bending needle assembly 10 in a surface-to-surface contact manner. This can increase the contact area between the push plate 42 when pushing the bending needle assembly 10, thereby improving the stability when the push plate 42 drives the bending needle swing seat 32 to move away from the limit block 31. Of course, in other embodiments, the push plate 42 can also directly push the bending needle swing seat 32.
[0044] like Figure 1As shown, the drive assembly 40 also includes an elastic member 43, which is sleeved on the looper shaft 20 and abuts against the looper swing seat 32, and the elastic member 43 can push the looper swing seat 32 to move toward the limit block 31. In this way, the elastic deformation of the elastic member 43 can be used to drive the looper swing seat 32 to move toward the limit block 31, so that the drive assembly 40 can simplify the structure of the drive assembly 40 on the basis of meeting the requirement for the looper swing seat 32 to reciprocate on the looper shaft 20. Here, the elastic member 43 is a spring, a bellows, a rubber sleeve with high elasticity, etc. Of course, in other embodiments, the telescopic movement of another telescopic drive member can also be used to drive the looper swing seat 32 to move toward the limit block 31, which will not be elaborated here.

Here, the retaining ring 50 is fixedly connected to the looper shaft 20 by a third fixing screw 103.
[0046] like Figure 1 As shown, the looper mechanism 100 further includes a connecting piece 60, which is arranged through the looper swing seat 32 and is threadedly connected to the looper assembly 10. In this way, the looper assembly 10 and the looper swing seat 32 can be assembled and connected, so as to facilitate the assembly between the looper swing seat 32 and the looper assembly 10. Here, the connecting piece 60 is a bolt, a screw, etc. Of course, in other embodiments, the looper assembly 10 and the looper swing seat 32 can also be assembled and connected by a buckle or interference fit.
