Its processing precision directly impacts product quality. To improve processing efficiency, knitted underwear dispensing devices with positioning functions are often used.

[0003] For example, Chinese patent publication number CN220027625U discloses an anti-drift, traceless underwear dispensing machine. This existing device uses a limiting structure to limit the underwear positioning frame, preventing the underwear positioning frame from slipping on the clothing placement board. The underwear positioning frame can position the underwear, preventing the underwear from shifting on the backlight assembly as a whole, ensuring accurate dispensing. However, in actual application, this existing device requires customized positioning frames for different styles of underwear, which takes a long time to change over, seriously restricting production efficiency. In addition, the positioning frame is only fixed by the set limiting columns. In actual production, the positioning frame is easy to loosen, causing the underwear to shift, resulting in reduced dispensing effect. Utility Model Content

[0004] The purpose of the utility model is to provide a knitted underwear dispensing device based on positioning and anti-biasing. The plunger selects the key positioning point according to the characteristics of the underwear pattern and is inserted to form an initial position lock. Then the first telescopic rod pushes the slider to drive the mounting seat to move radially, so that the positioning component adapts to the actual size of the underwear, and the second telescopic rod drives the L-shaped rod to rotate through the guide strip, and finally the positioning plate applies uniform pressure to the edge of the underwear.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a knitted underwear dispensing device based on positioning and anti-bias, comprising a base, an operating panel provided on the base, a first movable frame connected to the outer side of the base through a guide rail, a second movable frame movably provided outside the first movable frame, a dispensing machine for dispensing glue on the knitted underwear movably provided next to the second movable frame, a feeding device provided in the base, a first connecting seat provided at the feeding end of the feeding device, a movable seat fixed to the top of the first connecting seat, and a clothes placing board fixed to the top of the movable seat.

[0006] The top of the garment placement board is equipped with a positioning and anti-deviation assembly.

[0026] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] Example: See Figure 1-Figure 7 The utility model provides a technical solution: a knitted underwear dispensing device based on positioning and anti-bias, comprising a base 11, an operating panel 12 being provided on the base 11, a first movable frame 13 being connected to the outer side of the base 11 through a guide rail, a second movable frame 14 being movably provided outside the first movable frame 13, a dispensing machine 15 for dispensing glue on the knitted underwear being movably provided next to the second movable frame 14, a feeding device 21 being provided in the base 11, a first connecting seat 22 being provided at the feeding end of the feeding device 21, a movable seat 23 being fixed at the top end of the first connecting seat 22, and a clothes placing board 3 being fixed at the top end of the movable seat 23.

[0028] A positioning and anti-slip assembly 4 is installed at the top of the garment placement board 3. This assembly comprises a connecting slot 411 formed in the garment placement board 3. A plunger 412 is inserted into the slot 411 to assist in positioning the knitted underwear. A connecting cap 413 is secured to the top of the plunger 412. Once the plunger 412 is inserted into the slot 411, the cap 413 positions the underwear to be glued. This selective insertion allows for rapid adaptation to key stop points for different underwear styles, effectively preventing fabric slippage during processing.

[0029] Furthermore, at least three mounting blocks 426 are movably mounted on the top of the garment placement board 3. Each mounting block 426 is rotatably mounted within a connecting post 434. An L-shaped rod 435 is secured to the outside of the connecting post 434. A positioning plate 437 is secured to the side of the L-shaped rod 435 facing away from the connecting post 434. When the L-shaped rod 435 rotates, the positioning plate 437 abuts the knitted underwear to be glued. The L-shaped rod 435 and the positioning plate 437 form a lever-type clamping mechanism. This rotational action converts vertical driving force into horizontal fabric-fixing force, achieving precise positioning without damage.

[0030] Furthermore, at least thirty connecting grooves 411 are provided, and the thirty connecting grooves 411 are distributed along the circumference of the garment placement plate 3. The high density of the circumferentially distributed connecting grooves 411 expands the range of positioning point options and is compatible with the special version requirements of different types of underwear such as bras, panties, and body shapers.

[0031] Furthermore, the garment plate 3 is provided with limiting slots 421 corresponding to the mounting seats 426. A slider 422 is slidably disposed within each limiting slot 421, with the top end of each slider 422 fixedly connected to the bottom end of the corresponding mounting seat 426. The sliders 422 and limiting slots 421 form a guide mechanism that minimizes displacement deviation of the mounting seat 426 and provides a mechanical reference for multi-size adaptation.

[0032] Furthermore, a support plate 423 is fixed to the outer wall of the garment placement board 3. A second connecting seat 424 is fixed to the top of the support plate 423. A first telescopic rod 425 is embedded in the second connecting seat 424. The telescopic end of the first telescopic rod 425 is fixedly connected to the side of the slider 422. The first telescopic rod 425 forms a reaction force fulcrum through the support plate 423. Its ability to synchronously drive three or more mounting seats 426 enables the device to automatically adapt to different knitted underwear sizes.

[0033] Furthermore, each mounting base 426 is secured with a guide frame 431, to which a guide bar 432 is slidably connected. A mounting frame 433 is fixedly connected to the top of the guide bar 432. A movable sleeve 436 is rotatably connected to the side of the mounting frame 433 away from the guide bar 432. The movable sleeve 436 is movably mounted outside the L-shaped rod 435. The guide frame 431 and guide bar 432 form a two-stage displacement amplification mechanism, converting the small travel of the second telescopic rod 439 into a larger rotation angle of the L-shaped rod 435, thereby improving positioning response speed.

[0034] Furthermore, as guide bar 432 slides within guide frame 431, mounting frame 433 pulls movable sleeve 436 to move, causing L-shaped rod 435 to rotate. The kinematically optimized trajectory of movable sleeve 436 ensures that positioning plate 437 maintains surface contact with the fabric during rotation of L-shaped rod 435, avoiding localized stress concentration.

[0035] Furthermore, the positioning and anti-deviation assembly 4 includes a second telescopic rod 439 disposed within the mounting seat 426. The telescopic end of the second telescopic rod 439 is fixedly connected to the side of the guide bar 432 away from the mounting frame 433. The second telescopic rod 439 can be used to push or pull the guide bar 432 to slide within the guide frame 431, and the position of the guide bar 432 can be locked after positioning is completed.

[0036] Furthermore, a soft pad 438 is fixed to the bottom of the positioning plate 437. The pad 438 is made of silicone and has a non-slip texture on its working surface. The non-slip texture of the silicone pad 438 increases the static friction coefficient, while its elastic deformation absorbs fabric thickness deviations, ensuring a balance between positioning reliability and fabric protection.

[0037] The workflow of this positioning-based, anti-skew knitted underwear dispensing device is as follows: the operator lays the knitted underwear to be processed flat on top of the garment placement board 3, selects at least three key positioning points based on the underwear's pattern characteristics, and inserts a corresponding number of plungers 412 into the connecting grooves 411. The connecting caps 413 then pre-position the underwear by inserting the plungers 412 into the connecting grooves 411, preventing the underwear from slipping significantly.

[0038] The feeding device 21 is then activated, and the first connecting seat 22 drives the movable seat 23 and the garment placement plate 3 to adjust their horizontal displacement, moving the entire undergarment to the gluing station. At this point, the first telescopic rod 425 begins to operate, its telescopic end pushing the slider 422 along the limiting groove 421, driving the mounting seats 426 to simultaneously move toward the center of the disc or expand outward. This process is driven by the second connecting seat 424 on the support plate 423, resulting in the formation of a circular pattern of three or more mounting seats 426 that matches the size of the undergarment.

[0039] After mounting base 426 completes radial positioning, second telescopic rod 439 activates and pushes guide bar 432 to slide within guide frame 431. The axial displacement of guide bar 432 is translated into movement of movable sleeve 436 via mounting frame 433. As movable sleeve 436 moves along the outer wall of L-shaped rod 435, it creates a lever effect, forcing L-shaped rod 435 to rotate about the axis of connecting post 434. As L-shaped rod 435 swings, its end-mounted positioning plate 437, carrying cushion 438, gradually presses against the edge of the underwear. The silicone cushion 438, with its non-slip texture, creates a flexible contact with the fabric. While frictional resistance is generated between the positioning plate 437 and the underwear, the rotation of L-shaped rod 435 about connecting post 434 evenly distributes the positioning force across the underwear surface.

[0040] Ultimately, the coordinated actions of the plunger 412 and connecting slot 411, radial adjustment driven by the first telescopic rod 425, and angular compression driven by the second telescopic rod 439 achieve precise positioning and anti-skewing fixation of the underwear on the garment placement board 3. Once positioned, the first movable frame 13 moves outside the guide rails, and the second movable frame 14 enables the combined motion of the glue dispenser 15. Glue is dispensed to the designated area of ​​the underwear under the control of the program set by the operating panel 12. Throughout the entire process, the positioning assembly maintains the underwear in place, ensuring precise glue application.

[0041] The above embodiments merely represent one or several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
