Description

Technical Field

[0001] This utility model relates to the field of needle implantation machine technology, and specifically discloses a universal needle implantation machine needle holder adapter. Background Technology

[0002] As a core piece of equipment in the textile industry, needle insertion machines are widely used in the weaving process of products such as tufted carpets and embroidered fabrics. They carry needles through needle holders for high-speed piercing operations (typically at a frequency of 200-1500 times / minute). The needle holder, as a key component directly fixing the needles, needs frequent replacement with different specifications depending on process requirements (e.g., tufted needle holder diameter Φ8-12mm, embroidery needle holder Φ10-15mm). The connection between the needle holder and the needle holder frame of the needle insertion machine generally uses a standardized interface. Currently, the mainstream solution in the industry is to pre-set threaded holes or slots on the needle holder and directly lock the bottom of the needle holder with screws, or to customize a special mounting bracket for specific needle holders.

[0003] However, current technology has significant drawbacks:

[0004] Poor compatibility: A single needle holder can only be used with needle holders of a fixed diameter, which means that companies need to keep dozens of different needle holders in stock, increasing inventory costs.

[0005] Replacing the needle hub requires removing the locking screw, which takes an average of 3-5 minutes per needle hub, and the screw is easily lost. Utility Model Content

[0006] This invention proposes a universal needle holder adapter for needle implantation machines. Through an adjustable clamping mechanism, a single adapter can securely clamp needle holders of various diameters, eliminating the need for enterprises to stock a large number of dedicated needle holders and significantly reducing inventory costs and management burden.

[0007] This utility model is implemented as follows: a universal needle holder adapter for a needle implantation machine includes a base plate. Two left and right distributed shaft seats are fixedly connected to the front side of the upper end face of the base plate. A lead screw is rotatably connected between the two shaft seats. Two nut seats are threadedly connected to the outer wall of the lead screw. Guide rods are fixedly connected to the back of the two nut seats. Clamping blocks are fixedly connected to the lower end faces of the two guide rods. A slide rail is fixedly connected to the rear side of the upper end face of the base plate. Two sliders are slidably connected to the outer wall of the slide rail. The rear ends of the two guide rods are fixedly connected to the two sliders respectively.

[0008] As a preferred embodiment of the universal needle holder adapter of this utility model, each of the two clamping blocks has a V-shaped clamping cavity on one side opposite to the other.

[0009] As a preferred embodiment of the universal needle holder adapter of this utility model, the upper end surface of the substrate is provided with a through hole, and the two clamping blocks are symmetrically distributed on the left and right sides of the through hole.

[0010] As a preferred embodiment of the universal needle holder adapter of this utility model, the bottom of the base plate is fixedly connected to a support plate by multiple connecting posts, the lower end face of the support plate is fixedly connected to a standard interface, and the outer wall of the standard interface is provided with multiple mounting holes.

[0011] As a preferred embodiment of the universal needle holder adapter of this utility model, one end of the lead screw extends to the outside of the shaft seat and is provided with a handwheel.

[0012] As a preferred embodiment of the universal needle holder adapter of this utility model, a rubber pad is fixedly connected to the inner side of the clamping cavity.

[0013] As a preferred embodiment of the universal needle holder adapter of this utility model, the upper surface of the support plate is coated with a wear-resistant coating.

[0014] The beneficial effects of this utility model are:

[0015] This invention improves the versatility and efficiency of needle holder replacement in needle implantation machines. Through an adjustable clamping mechanism, a single adapter can securely clamp needle holders of various diameters, eliminating the need for companies to stock large quantities of dedicated needle holders and significantly reducing inventory costs and management burden. The manual screw-driven clamping design, combined with a slide rail guide, V-shaped clamping surface, and anti-slip rubber pads, enables quick and reliable clamping and release of needle holders. The replacement process requires no tools, completely avoiding the tedious and time-consuming process of screw removal and the risk of loss, making operation simple and fast. A standard bottom interface ensures a unified connection between the adapter and the needle holder of the needle implantation machine, resulting in a stable and reliable structure. The overall design significantly improves equipment utilization and production flexibility. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0022] Please see Figure 1-3 A universal needle holder adapter for a needle implantation machine includes a base plate 1. Two left and right distributed bearing seats 2 are fixedly connected to the front side of the upper end face of the base plate 1. A lead screw 3 is rotatably connected between the two bearing seats 2. Two nut seats 4 are threadedly connected to the outer wall of the lead screw 3. Guide rods 5 are fixedly connected to the back of the two nut seats 4. Clamping blocks 6 are fixedly connected to the lower end face of the two guide rods 5. A slide rail 8 is fixedly connected to the rear side of the upper end face of the base plate 1. Two sliders 9 are slidably connected to the outer wall of the slide rail 8. The rear ends of the two guide rods 5 are fixedly connected to the two sliders 9 respectively.

[0023] In this embodiment: rotating the handwheel 15 drives the lead screw 3 to rotate, causing the two nut seats 4 and the connected guide rod 5 and clamping block 6 to move synchronously in opposite directions under the guidance of the slide rail 8. The V-shaped clamping cavity 7 on the inner side of the clamping block 6 adaptively clamps or releases needle seats of different diameters. A through hole 10 is opened in the center of the base plate 1, which facilitates the needle seat to pass through the through hole 10 and be supported by the support plate 12, thereby improving the installation stability. The clamping block 6 is symmetrical on both sides of the through hole 10. The support plate 12 is fixed below the base plate 1 by the connecting column 11. The standard interface 13 is installed on the bottom surface of the support plate 12 for uniform connection to the needle holder of the needle implantation machine. The clamping cavity 7 is lined with a rubber pad 16 to enhance friction and prevent slippage. The upper surface of the support plate 12 is coated with a wear-resistant coating to improve durability, so as to realize that a single adapter can quickly and stably clamp needle seats of various specifications and uniformly connect to the needle holder.

[0024] As a technical optimization of this utility model, V-shaped clamping cavities 7 are provided on the opposite sides of the two clamping blocks 6.

[0025] In this embodiment: the V-shaped clamping cavity 7 utilizes the principle of inclined plane self-centering, which can more stably adapt to and clamp cylindrical needle seats of different diameters, increase the contact area, and prevent skewing.

[0026] As a technical optimization of this utility model, a through hole 10 is provided on the upper end surface of the substrate 1, and two clamping blocks 6 are symmetrically distributed on the left and right sides of the through hole 10.

[0027] In this embodiment, a through hole 10 is provided in the center of the substrate 1, which facilitates the needle holder to pass through the through hole 10 and be supported by the support plate 12, thereby improving installation stability.

[0028] As a technical optimization of this utility model, the bottom of the substrate 1 is fixedly connected to a support plate 12 by a plurality of connecting posts 11, and the lower end face of the support plate 12 is fixedly connected to a standard interface 13, and the outer wall of the standard interface 13 is provided with a plurality of mounting holes 14.

[0029] In this embodiment: the support plate 12 is connected to the base plate 1 through the connecting column 11, providing a basis for installing the standard interface 13. The standard interface 13 has a pre-set mounting hole 14, which realizes the standardization, unification and quick connection between the adapter and the needle holder of the needle implantation machine, eliminating the need to replace the needle holder itself.

[0030] As a technical optimization of this utility model, one end of the lead screw 3 extends to the outside of the bearing seat 2 and is provided with a handwheel 15.

[0031] In this embodiment, one end of the lead screw 3 extends to the outside of the bearing seat 2 and is provided with a handwheel 15, which facilitates driving the lead screw 3 to rotate via the handwheel 15.

[0032] As a technical optimization of this utility model, a rubber pad 16 is fixedly connected to the inner side of the clamping cavity 7.

[0033] In this embodiment, the rubber pad 16 increases the friction between the clamping cavity 7 and the needle seat surface, preventing the needle seat from slipping or rotating during operation, improving clamping reliability, and protecting the needle seat surface from hard friction damage.

[0034] As a technical optimization of this utility model, the upper surface of the support plate 12 is coated with a wear-resistant coating.

[0035] In this embodiment, the wear-resistant coating on the upper surface of the support plate 12 effectively reduces the wear of the pin seat on the support plate 12, and significantly extends the service life of the key load-bearing components of the adapter.

[0036] The working principle and usage process of this utility model are as follows: In use, the needle holder is placed vertically on the upper surface of the base plate 1. The working end of the needle holder is inserted into the through hole 10, and the bottom end is supported by the support plate 12. The operator rotates the handwheel 15 to drive the lead screw 3 to rotate. The rotational motion of the lead screw 3 is converted into the linear motion of the two nut seats 4 through a thread. Since the back of the nut seat 4 is fixedly connected to the guide rod 5, and the rear end of the guide rod 5 is fixedly connected to the slider 9 on the slide rail 8, the slider 9 constrains the guide rod 5 to slide precisely only along the direction of the slide rail 8 (i.e., the left and right horizontal direction). Therefore, the rotation of the lead screw 3 drives the two nut seats 4... Guide rod 5 and its lower clamping block 6 move synchronously towards each other under the guidance of slide rail 8; the V-shaped clamping cavities 7 inside the two clamping blocks 6 close accordingly, and automatically adapt to and firmly hold the outer cylindrical surface of the needle holder by utilizing the self-centering effect of the V-shaped inclined surface, and the rubber pad 16 enhances the clamping friction; when the needle holder needs to be replaced, turn the handwheel 15 in the opposite direction, and the screw 3 drives the nut seat 4, guide rod 5 and clamping block 6 to separate in the opposite direction, so that the current needle holder can be released and taken out, and a new specification needle holder can be inserted and re-clamped; the bottom of the adapter is uniformly fixed to the needle holder of the needle implantation machine through the standard interface 13 and its mounting hole 14.
