Description

Technical Field

[0001] This utility model relates to a rope embroidery loop head structure. Background Technology

[0002] The looper head is a key component of a rope embroidery machine, used in conjunction with the machine needle to perform rope embroidery. During the rope embroidery process, the looper head rotates at high speed according to the pattern requirements while outputting the rope.

[0003] Existing loop-forming head structures typically mount bearings on the connecting plate of the rope feeding device, driving its rotation via a drive belt. For example, existing loop-forming head drive shafts only have bearings on the upper or lower side of the driven pulley. Because the loop-forming head needs an internal cavity for the needle to pass through, the outer diameter of its drive shaft and the mounted bearings is limited, resulting in smaller bearing sizes and thinner bearing walls. Furthermore, the drive belt usually applies driving force from only one side of the bearing, causing an angle between the bearing's force direction and its preset optimal radial force direction, leading to uneven force distribution. Under high-speed operation of the loop-forming head, the single-bearing structure is prone to premature damage due to uneven loading, requiring frequent downtime for replacement, increasing maintenance costs and impacting production efficiency. Utility Model Content

[0004] This invention addresses the problem of easily damaging bearings in existing rope embroidery loop head structures by providing a rope embroidery loop head structure that optimizes bearing installation and extends bearing life.

[0005] The technical solution of this utility model to solve the existing problems is: a rope embroidery loop head structure, including a connecting plate set on the rope feeding device, a loop head set on the connecting plate, a passive pulley on the loop head, and a transmission belt between the passive pulley and the drive pulley on the rope feeding device. As an improvement, bearings are installed on both axial sides of the loop head on the passive pulley, and the connecting plate is provided with mounting holes that cooperate with the two bearings on both axial sides of the passive pulley.

[0006] As a further improvement, a drive shaft is provided above the ring-forming head, and the passive pulley and bearings on both sides of the axial direction are all mounted on the drive shaft, which is provided with receiving holes.

[0007] As a further improvement, the connecting plate is provided with a mounting groove for mounting a transmission belt at the passive pulley.

[0008] Compared with the prior art, this utility model has bearings installed on both axial sides of the driven pulley at the ring-forming head, and mounting holes for the two bearings on both axial sides of the driven pulley are provided on the connecting plate. The bearings are located on both sides of the driven pulley, and the bearings on both sides can evenly bear the tension of the transmission belt. Its advantages are: 1. Optimize stress distribution and extend service life: By symmetrically setting two bearings on both sides of the driven pulley along the axis, the radial force generated by the transmission belt is decomposed and borne by the two bearings together, which greatly improves the stress state of a single bearing. This allows the bearing to mainly bear its designed radial load, avoiding early failure caused by off-center loading, and thus significantly extending the service life of the bearing and even the entire ring head structure.

[0009] 2. Improved operational stability: The dual-bearing support structure enhances the rigidity of the drive shaft, reduces vibration and sway at high speeds, and makes the ring-forming head run more smoothly and reliably, which helps to improve the quality of rope embroidery.

[0010] 3. Reasonable structure and easy to implement: The structure is cleverly improved. It can be achieved by simply adding a bearing mounting hole to the existing connecting plate and selecting a standard bearing. The modification cost is low and it is easy to promote and apply on existing equipment. Attached Figure Description

[0019] See Figure 1-7This embodiment discloses a loop-making head structure for rope embroidery, comprising a connecting plate 1 mounted on a rope feeding device, and a loop-making head 2 mounted on the connecting plate 1. The loop-making head 2 has a driven pulley 3, and a transmission belt 5 connects the driven pulley 3 to a drive pulley 4 on the rope feeding device. The drive pulley 4 is typically also mounted on the connecting plate 1 and connected to a drive motor 41 via a transmission shaft. The loop-making head 2 is used to feed rope in conjunction with the needle and rotates the rope feeding according to the rope embroidery process. The connecting plate 1 is connected to the mounting frame of the rope feeding device. Receiving grooves are typically provided on the connecting plate 1 at the locations of the drive pulley 4, the driven pulley 3, and the transmission belt 5.

[0020] Other structures of the rope feeding device, such as the mounting frame, the rope feeding structure set above the mounting frame, the drive motor for driving the loop head 2, the transmission pulley assembly, and the loop head 2 with receiving holes, can all adopt existing technologies.

[0021] To facilitate the production and installation of the ring-forming head 2, a drive shaft 21 is provided above the ring-forming head 2. The drive shaft 21 is used to install the passive pulley 3, which cooperates with the inner ring of the bearing 11. The passive pulley 3 and the bearings 11 on both sides of the axial direction are all installed on the drive shaft 21. The drive shaft 21 is provided with a receiving hole to accommodate the passage of the machine needle.

[0022] The ring-forming head 2 is equipped with bearings 11 on both axial sides of the driven pulley 3. The connecting plate 1 has mounting holes 12 that mate with the two bearings 11 on both axial sides of the driven pulley 3. The mounting holes 12 mate with the outer rings of the bearings. When the bearings are installed on both axial sides of the driven pulley 3, and the drive pulley 4 drives the transmission belt 5 to drive the driven pulley 3 and the ring-forming head 2, the two bearings 11 on both axial sides of the driven pulley 3 can effectively balance the force on the driven pulley 3, allowing the two bearings to bear more purely radial force, which is parallel to the preset radial force of the bearings. This makes the force on the bearings more reasonable and can effectively extend the bearing life.

[0023] The connecting plate 1 is provided with a mounting groove 6 for installing the transmission belt at the passive pulley 3. The mounting groove 6 facilitates the installation of the transmission belt 5.

[0024] The passive pulley 3 can be integrated with the ring head. In this embodiment, as a preferred option, the passive pulley is mounted on the drive shaft 21 and integrated with the drive shaft 21.
