Description

Technical Field

[0001] This utility model relates to the field of automatic printing equipment technology, specifically to a liquid Lycra flow adjustable glue dispensing mechanism. Background Technology

[0002] Liquid Lycra is currently mainly used in shapewear, particularly in the support areas. The amount of liquid Lycra applied to the garment fabric qualitatively and quantitatively determines the shaping or support strength of these areas. Traditional liquid Lycra printing technologies mainly include two types: manual printing and elliptical machine printing. Manual printing has no quantity limit but low efficiency; elliptical machine printing has high order volume requirements. Both traditional printing methods require the fabrication of nylon screens on which the printed pattern is engraved, making precise control of the amount of liquid Lycra applied impossible. Therefore, a liquid Lycra flow rate adjustable dispensing mechanism is proposed.

[0003] To better flatter the figure, adjustments should be made to the body in a more precise way. For example, the pressure of the fabric on the hips needs to be reduced to allow the flesh to be released more easily; similarly, the pressure of the fabric on the lower abdomen needs to be increased for a better tummy-flattening effect. Lightweight support is provided through variations in the density of the printed pattern—whether thick or thin, dense or sparse, intermittent or continuous—thus achieving a balance between precise shaping and comfortable wear. Therefore, liquid Lycra printing has strict requirements for the uniformity of the adhesive application and the density and spacing of the patterns. Utility Model Content

[0004] To address the aforementioned issues, a liquid Lycra flow adjustable dispensing mechanism is provided. This mechanism utilizes the varying gap width between the spherical roller and the second spherical arc groove to alter the dispensing volume of the liquid Lycra while maintaining the same rolling speed, thereby achieving adjustment of the dispensing thickness.

[0005] To solve the problems of the prior art, this utility model provides a liquid Lycra flow adjustable dispensing mechanism, including a dispensing tube and a servo motor. The bottom of the dispensing tube is provided with a first spherical arc groove and a number of dispensing grooves located on the wall of the first spherical arc groove and distributed circumferentially. A spherical roller is installed inside the first spherical arc groove.

[0006] The bottom end of the dispensing hose is fitted with a threaded sleeve. The outer wall of the top end of the threaded sleeve is provided with toothed grooves at equal intervals around its central axis. The threaded sleeve is threaded to fit the dispensing hose. The inside of the threaded sleeve is provided with a second spherical arc groove that can be adapted to the spherical roller.

[0007] The output end of the servo motor is fixed with a gear that can mesh with the tooth groove.

[0008] Preferably, the servo motor is fixedly installed on the dispensing pipe or at the bottom of the float.

[0009] Preferably, the outer surface of the dispensing tube is fitted with a fixing sleeve, and the top of the fixing sleeve is fixed to the bottom surface of the float plate.

[0010] Preferably, the float plate is longitudinally fixed with sliding rods on both sides, the sliding rods are located inside the limiting sleeve and can move along the central axis of the limiting sleeve.

[0011] Preferably, a limiting block for limiting is fixed on the slide rod, and a return spring is provided on the top of the limiting block. The return spring is sleeved on the slide rod, and the top of the return spring contacts the bottom of the pressure sensor. The pressure sensor is fixed on the lower end face of the limiting sleeve.

[0012] Preferably, the servo motor is fixedly installed on the dispensing pipe or at the bottom of the float.

[0013] Preferably, the opening diameter of the second spherical arc groove is smaller than the diameter of the spherical roller.

[0014] The advantages of this utility model compared to the prior art are:

[0015] 1. This application utilizes a dispensing tube to synchronously move a spherical roller, causing the bottom of the spherical roller to roll against the fabric surface through friction. As the spherical roller rolls, the material inside the dispensing tube adheres to its surface. The rolling of the spherical roller carries the material from the dispensing tube out and coats it onto the fabric surface, thus achieving uniform material distribution.

[0016] 2. This application utilizes a servo motor to drive a meshing toothed groove to rotate clockwise or counterclockwise via a gear at its output end. Simultaneously, the toothed groove rotates, causing the threaded sleeve to move longitudinally along the central axis of the dispensing tube. This adjusts the spatial distance between the spherical roller and the first and second spherical arc grooves. By utilizing the different gap widths between the spherical roller and the second spherical arc groove, the dispensing volume at the same rolling speed is altered, thus achieving adjustment of the thickness of the liquid Lycra dispensing. Furthermore, after the dispensing tube rises, the roller's own weight seals the second spherical arc groove, preventing material leakage. Attached Figure Description

[0024] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0025] See Figures 1-6 As shown, a liquid Lycra printing device includes a three-dimensional moving machine tool 1, an installation mechanism disposed at the working end of the three-dimensional moving machine tool 1, a feeding mechanism 3 disposed on the installation mechanism, a buffer mechanism 5 disposed at the bottom of the feeding mechanism 3, and a glue dispensing mechanism 6 disposed on the buffer mechanism 5. The feeding mechanism 3 includes a storage tank 31 longitudinally installed inside the installation mechanism. A discharge nozzle 311 that can communicate with the inside of the storage tank 31 is longitudinally fixed at the bottom end of the storage tank 31. A heating mechanism is provided inside the storage tank 31. The heating mechanism is a conventional technology and will not be described in detail here.

[0026] The glue dispensing mechanism 6 includes a glue dispensing pipe 61 longitudinally fixed to the bottom of the buffer mechanism 5. An elastic feeding pipe 511 is installed at the top of the glue dispensing pipe 61, and the top of the elastic feeding pipe 511 is connected to the bottom of the discharge nozzle 311. The bottom of the glue dispensing pipe 61 has a first spherical arc groove 611 and several circumferentially distributed glue dispensing grooves located on the wall of the first spherical arc groove 611. A spherical roller 612 is installed inside the first spherical arc groove 611. A threaded sleeve 62 is fitted onto the bottom end of the glue dispensing pipe 61. Gear grooves 622 are equidistantly formed on the outer wall of the top of the threaded sleeve 62 around its central axis. The threaded sleeve 62 is threadedly engaged with the glue dispensing pipe 61. The inside of the threaded sleeve 62 is provided with a second spherical arc groove 621 that can fit the spherical roller 612. The opening diameter of the second spherical arc groove 621 is smaller than the diameter of the spherical roller 612.

[0027] A servo motor 7 is fixedly mounted on the side wall of the hose 61, and a gear 71 that can mesh with the toothed groove 622 is fixed at the output end of the servo motor 7. In some other examples, the servo motor 7 may also be fixedly mounted on the bottom of the float 51.

[0028] A first spherical arc groove 611 is formed at the bottom end of the dispensing tube 61, and a spherical roller 612 is installed inside the first spherical arc groove 611. A second spherical arc groove 621 is formed inside the threaded sleeve 62 to fit the surface of the spherical roller 612, and the bottom of the spherical roller 612 protrudes downward from the bottom of the threaded sleeve 62. When the buffer mechanism 5 drives the dispensing tube 61 to move downward, the bottom of the spherical roller 612 will contact the fabric surface. When the dispensing tube 61 moves horizontally, the dispensing tube 61 drives the spherical roller 612 to move synchronously, so that the bottom of the spherical roller 612 rolls with the fabric surface through friction. While the spherical roller 612 rolls, the material in the dispensing tube 61 will adhere to the surface of the spherical roller 612. The rolling of the spherical roller 612 carries the material in the dispensing tube 61 out and coats it on the fabric surface, thereby achieving uniform material distribution.

[0029] The heating mechanism ensures that the liquid Lycra in the storage tank 31, the dispensing nozzle 311, and the dispensing tube 61 remains in a fluid state within the dispensing tube 61, effectively preventing the liquid Lycra from solidifying and causing blockage. The servo motor 7 starts, and through its output gear 71, it drives the meshing toothed groove 622 to rotate clockwise or counterclockwise. As the toothed groove 622 rotates, it drives the threaded sleeve 62 to move longitudinally along the central axis of the dispensing tube 61, thereby adjusting the spatial distance between the spherical roller 612 and the first spherical arc groove 611 and the second spherical arc groove 621. By utilizing the different gap widths between the spherical roller 612 and the second spherical arc groove 621, the dispensing volume at the same rolling speed is changed, achieving adjustment of the thickness of the liquid Lycra dispensing. Combined with the control of three-dimensional motion, this enables the distribution of density and the creation of intermittent or continuous lines. After the hose 61 rises, the spherical roller 612 seals the second spherical arc groove 621 by its own weight, preventing material leakage.

[0030] See Figure 4 As shown, the buffer mechanism 5 includes a float 51 for mounting the glue supply tube 61. A fixing sleeve 512 is fitted around the outside of the glue supply tube 61, and the top of the fixing sleeve 512 is fixed to the bottom surface of the float 51.

[0031] To ensure a stable connection between the float plate 51 and the dispensing pipe 61, a fixing sleeve 512 is fitted onto the outside of the dispensing pipe 61, and then the top of the fixing sleeve 512 is welded to the lower end face of the float plate 51. This fixes the dispensing pipe 61 to the float plate 51 via the fixing sleeve 512, thus ensuring a stable connection between the float plate 51 and the dispensing pipe 61.

[0032] See Figure 2 , Figure 3 As shown, the installation mechanism includes a movable frame 21 installed at the working end of the three-dimensional moving machine tool 1; a first fixed frame 22 is welded to one side of the movable frame 21; and a storage tank 31 is installed between the movable frame 21 and the first fixed frame 22.

[0033] By mounting the movable frame 21 on the working end of the three-dimensional moving machine tool 1, the three-dimensional moving machine tool 1 can drive the movable frame 21 to move along the X-axis, Y-axis, and Z-axis directions. The drive mechanisms in the X-axis, Y-axis, and Z-axis directions are conventional technologies and will not be described in detail here. Preferably, the drive mechanism is a motor-screw module. By installing a first fixed frame 22 on one side of the movable frame 21, the first fixed frame 22 cooperates with the movable frame 21 to fix the storage tank 31, thereby ensuring the stability of the storage tank 31.

[0034] See Figure 2 , Figure 3 As shown, limit sleeves 211 are symmetrically fixed on both sides of the movable frame 21. The limit sleeves 211 are fixed to the top and bottom of the side of the movable frame 21 respectively. A pressure sensor 212 is fixed on the lower end face of the limit sleeve 211 near the top of the movable frame 21. Slide rods 52 are longitudinally fixed on both sides of the float plate 51. The slide rods 52 are located inside the limit sleeves 211 and can move along the central axis of the limit sleeves 211.

[0035] To ensure the stability of the float 51, sliding rods 52 are longitudinally installed on both sides of the float 51 and fitted into the limiting sleeve 211. When the float 51 moves longitudinally, the sliding rods 52 slide synchronously along the inner wall of the limiting sleeve 211. Through the coordinated action of the limiting sleeve 211 and the sliding rods 52, the float 51 is limited, thus ensuring its stability during movement.

[0036] See Figure 2 , Figure 3 As shown, a limiting block 522 for limiting is fixed on the slide rod 52; a reset spring 521 is provided on the top of the limiting block 522, the reset spring 521 is fitted on the slide rod 52, and the top of the reset spring 521 is in contact with the bottom of the pressure sensor 212.

[0037] When the slide bar 52 moves upward, the limiting block 522 fixed on the slide bar 52 compresses the return spring 521, causing the return spring 521 to gradually accumulate elastic potential energy. As the elastic potential energy accumulated by the return spring 521 continues to increase, the pressure exerted by the return spring 521 on the pressure sensor 212 also increases accordingly. When the pressure sensor 212 detects that the pressure exceeds a preset value, the longitudinal movement of the three-dimensional moving machine tool 1 will immediately stop.

[0038] See Figure 2As shown, a constant pressure pump 34 and a pressure detection sensor for stabilizing the internal pressure are also fixed on the top of the storage tank 31. The output end of the constant pressure pump 34 is connected to the inside of the storage tank 31.

[0039] A constant pressure pump 34 is installed on top of the storage tank 31. When the pressure sensor detects that the pressure inside the storage tank 31 is higher or lower than a preset value, the constant pressure pump 34 is activated to perform pressure relief or pressurization operations inside the storage tank 31. This measure effectively ensures that the pressure inside the storage tank 31 is always maintained within the preset range, avoiding problems such as excessively high pressure leading to excessively fast discharge or excessively low pressure leading to slow discharge. This ensures stable feeding by the feeding mechanism 3.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
