Description

Technical Field

[0001] The utility model relates to the technical field of heavy-duty embroidery machines, and more specifically, to a needle bar device of a heavy-duty embroidery machine. Background Art

[0002] Traditional embroidery machines are usually suitable for general light and thin fabrics, but for embroidery of thick materials (such as denim, canvas, etc.), specially designed thick material embroidery machines are required. Thick material embroidery machines are usually equipped with stronger penetration capabilities and can embroider smoothly on thick fabrics without needle jams or thread breaks. The needle bar is an important component of the thick material embroidery machine. The needle bar is the main component used to support and drive the embroidery needle.

[0003] When the needle bar device of the existing computer embroidery machine is embroidering, since the existing device is not provided with a device to process the vibration generated during operation, the needle bar may break due to vibration, which affects the service life of the needle bar device and the service life of the needle bar of the computer embroidery machine and increases the cost investment of the manufacturer.

[0004] The utility model with announcement number CN214142834U discloses a needle bar device for a computer embroidery machine. A support frame is installed on the embroidery machine, and the embroidery machine starts to operate. The embroidery needle performs high-speed embroidery work. At this time, the needle bar swings left and right or moves up and down. The up and down movement of the needle bar pushes the fixed ring and the connecting ring to move up and down. The shock-absorbing spring inside the shock absorber is elastic so that the shock-absorbing spring can freely expand and contract, thereby achieving a shock-absorbing effect. The installation of the shock absorber greatly increases the service life of the needle bar device and the needle bar of the computer embroidery machine and reduces the cost.

[0005] When the needle bar device is in use, the shock absorber is connected to the support frame by screwing the No. 1 bolt and the No. 1 bolt hole, but the support frame is not convenient to be connected to the driving mechanism. If the support frame is directly welded to the driving mechanism, it is not convenient to disassemble and replace the support frame when it is damaged. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides a needle bar device of a thick material embroidery machine, aiming to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a needle bar device of a thick material embroidery machine, comprising a support frame, a needle bar body is movably arranged at the bottom of the support frame, a vertical plate is fixedly connected to the top center position of the support frame, a first mounting plate is fixedly connected to the top of the vertical plate, two second mounting plates are movably arranged on the first mounting plate, a connecting assembly is arranged between the two second mounting plates, the connecting assembly comprises a threaded rod and a threaded extrusion sleeve, one end of the threaded rod passes through the two second mounting plates, and the two threaded extrusion sleeves are movably sleeved on the threaded rod.

[0008] Furthermore, two sleeves are fixedly connected on both the front and rear sides of the vertical plate, and one end of the threaded rod passes through two of the sleeves.

[0009] It can be seen that in the above technical solution, the sleeve can provide limited support for the threaded rod.

[0010] Furthermore, four limiting rods are fixedly connected to the top end of the support frame, and the top ends of the four limiting rods respectively penetrate the two second mounting plates.

[0011] It can be seen that in the above technical solution, the limiting rod can provide limiting support for the second mounting plate.

[0012] Furthermore, a side ring is fixedly mounted on the needle rod body, a buffer assembly is disposed on the top of the side ring, and the buffer assembly includes a convex tube, a circular plate, a buffer pad and a buffer spring.

[0013] Furthermore, the top end of the convex tube passes through the support frame, and the bottom end of the convex tube extends into the needle rod body, the circular plate is fixedly sleeved on the convex tube, the top end of the buffer pad is fixedly connected to the circular plate, the top end of the buffer spring is fixedly connected to the buffer pad, and the bottom end of the buffer spring is fixedly connected to the side ring.

[0014] Furthermore, a threaded sleeve is threadedly connected to the convex tube, and the threaded sleeve is located inside the support frame.

[0015] It can be seen that in the above technical solution, when the threaded sleeve is away from the convex tube, the fixation between the convex tube and the support frame can be released, and the needle rod body can be inspected and replaced.

[0016] Furthermore, a gasket is movably provided at the bottom of the threaded sleeve, and the bottom end of the gasket is in contact with the support frame.

[0017] It can be seen that in the above technical solution, the gasket can improve the firmness between the threaded sleeve and the support frame.

[0018] Technical effects and advantages of the utility model:

[0019] 1. The utility model places the first mounting plate on the driving mechanism of the thick material embroidery machine, and fixes the first mounting plate to the driving mechanism of the thick material embroidery machine through four bolts. When the contact area between the driving mechanism of the thick material embroidery machine and the first mounting plate is small, the threaded extrusion sleeve is rotated and moved away from the threaded rod, thereby releasing the fixation between the threaded rod and the two second mounting plates, and the two second mounting plates are moved upward and located on both sides of the driving mechanism of the thick material embroidery machine, and then the two second mounting plates are fixed to the driving mechanism of the thick material embroidery machine through four bolts. Similarly, the support frame is disassembled, which is simple to operate, convenient to use, and has a wide range of applications.

[0020] 2. In the utility model, when the needle bar body moves upward, the needle bar body drives the side ring to move upward, thereby driving the buffer spring to compress, and the buffer pad absorbs the energy generated by the deformation of the buffer spring, thereby achieving an effective buffering effect. The threaded sleeve is rotated and moved away from the convex tube, and then lubricating oil is added to the convex tube. The lubricating oil lubricates the convex tube and the needle bar body. The structure is simple and the service life is long. BRIEF DESCRIPTION OF THE DRAWINGS
