Description

Technical Field

[0001] This utility model relates to the field of fabric adhesive application technology, specifically a ball-type adhesive head for fabric adhesive application. Background Technology

[0002] Currently, when non-woven underwear crotch material and main body material are combined, they are usually glued together by spraying. A fixed glue spraying device will form regularly arranged glue marks on the back of the crotch material during the fabric transfer process. After the crotch material is cut, it is transferred by the adsorption device and adheres to the main body material.

[0003] In actual production, to avoid issues such as excessive or misaligned glue application in the crotch area, or glue overflow, a 3-5mm blank space is often left before applying glue to the crotch area. However, leaving a blank space in the crotch area can cause burrs to form after the non-woven underwear is cut. The crotch material is also prone to delamination, especially when changing sanitary napkins during menstruation. The strong adhesive on the back of the sanitary napkin can easily peel the crotch material away from the blank space, resulting in the exposure of the hot air layer on the back of the crotch area and lint shedding.

[0004] In view of this, a ball-type glue applicator for applying adhesive to fabric is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a ball-type adhesive applicator for fabric coating, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ball-type adhesive applicator for fabric application, comprising, A glue-applying box, wherein the interior of the glue-applying box is provided with a glue storage chamber and a glue dispensing channel, the top of the glue-applying box is provided with a glue inlet and the bottom of the glue-applying box is provided with a glue outlet; A ball bearing head, comprising a connecting cylinder detachably connected to the dispensing port, the connecting cylinder having an opening at the top and a limiting cavity at the bottom, a ball bearing head being disposed inside the limiting cavity, and the bottom portion of the ball bearing head extending to the outside; The inner wall of the top end of the connecting cylinder is provided with an inclined layer, and a limiting cylinder is inserted into the surface of the inclined layer. The bottom end of the limiting cylinder extends into the interior of the limiting cavity and abuts against the surface of the ball head. A spring is sleeved on the outer wall of the limiting cylinder extending into the interior of the connecting cylinder, and a positioning ring for limiting the spring is provided on the outer wall of the bottom end of the limiting cylinder.

[0007] Preferably, the outer wall of the top of the connecting cylinder is provided with a threaded layer, and the connecting cylinder is threadedly connected to the glue outlet through the threaded layer.

[0008] Preferably, a plurality of screws are rotatably connected to the upper part of the front of the glue dispensing box, wherein the other end of the screws extends into the interior of the glue dispensing box and is threadedly connected to a sealing plate, the sealing plate moving along the axial direction of the screws to open and close the glue dispensing channel.

[0009] Preferably, the bottom outer wall of the limiting cylinder is provided with a notch and an arc-shaped layer, the height of the notch extends into the interior of the connecting cylinder, wherein the arc-shaped layer abuts against the surface of the ball head.

[0010] Preferably, the end of the screw extending outside the glue-applying box is provided with a knob, and the surface of the knob is provided with anti-slip texture.

[0011] Preferably, the number of ball bearing heads is several, and they are evenly spaced at the bottom of the glue application box.

[0012] This utility model has the following beneficial effects: This type of fabric adhesive applicator uses a ball-type applicator to precisely control the application trajectory and range. Unlike traditional spray adhesives, it eliminates the need to leave a 3-5mm blank space beforehand to avoid excessive, misaligned, or overflowing adhesive. This fundamentally solves the problem of burrs caused by leaving blank spaces after cutting non-woven underwear, prevents the crotch material from delaminating, and especially prevents the strong adhesive on menstrual sanitary napkins from peeling the crotch material from the blank space, reducing the exposure of the back heat air layer and lint shedding. This type of ball-type glue head for fabric coating, through the cooperation of the limiting cylinder and the spring, can ensure that the ball head always closely contacts the fabric surface, ensuring uniform and stable glue application pressure, avoiding the problems of glue overflow and uneven glue amount in traditional spraying. At the same time, the insertion structure of the inclined layer and the limiting cylinder can accurately limit the glue application position and reduce the risk of glue misalignment. This is a ball-type glue head for applying adhesive to fabric. The connecting cylinder is detachably connected to the glue outlet through a threaded layer, which facilitates the individual disassembly, cleaning, or replacement of the ball-type glue head, reducing maintenance costs. By rotating the screw, the sealing plate can be driven to close the glue outlet channel, thus facilitating the sealing of the disassembled glue outlet. With the disassembled ball-type glue head, the required spacing for glue application can be adjusted. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1 to 6 This utility model provides a ball-type glue applicator for applying adhesive to fabric; including, The glue-applying box 1 has a glue storage chamber 2 and a glue outlet channel 17 inside. The top of the glue-applying box 1 has a glue inlet 4 and the bottom of the glue-applying box 1 has a glue outlet 5. The ball head 3 includes a connecting cylinder 301 detachably connected to the dispensing port 5. The top of the connecting cylinder 301 is provided with an opening 302 and the bottom is provided with a limiting cavity 303. The ball head 304 is provided inside the limiting cavity 303 and the bottom part of the ball head 304 extends to the outside. The inner wall of the top end of the connecting cylinder 301 is provided with an inclined layer 6, and a limiting cylinder 7 is inserted into the surface of the inclined layer 6. The bottom end of the limiting cylinder 7 extends into the interior of the limiting cavity 303 and abuts against the surface of the ball head 304. A spring 8 is sleeved on the outer wall of the limiting cylinder 7 extending into the interior of the connecting cylinder 301, and a positioning ring 9 for limiting the spring 8 is provided on the outer wall of the bottom end of the limiting cylinder 7.

[0017] When applying adhesive to the fabric, the ball bearing head 3 is positioned above the fabric; When the ball head 304 is not in contact with the fabric, the limiting cylinder 7 abuts against the surface of the ball head 304 under the action of the spring 8, and the ball head 304 abuts against the outlet at the bottom of the limiting cavity 303, thereby sealing the glue outlet. When the ball head 304 contacts the fabric, and the ball head 304 moves upward a suitable distance, it applies a force to the limiting cylinder 7. With the cooperation of the positioning ring 9, the spring 8 gradually contracts, and the top of the limiting cylinder 7 moves upward. At this time, the glue outlet 5 and the bottom of the limiting cavity 303 open, and the glue is coated on the surface of the ball head 304. When the ball head 304 moves, it rotates and drives the glue to be coated on the surface of the fabric. When the ball head 304 is not in contact with the fabric, it can automatically close the glue outlet 5. When the ball head 304 is in contact with the fabric, it is convenient to dispense glue, making it easy to use. If the fabric deviates and the ball head 304 is compressed, the ball head 304 can automatically close the glue outlet 5 to prevent glue overflow.

[0018] The outer wall of the top of the connecting cylinder 301 is provided with a threaded layer 10. The connecting cylinder 301 is threadedly connected to the glue outlet 5 through the threaded layer 10, which facilitates subsequent disassembly and facilitates rapid maintenance of the production line.

[0019] Several screws 11 are rotatably connected to the upper part of the front of the glue dispensing box 1. The other end of the screw 11 extends into the interior of the glue dispensing box 1 and is threadedly connected to a sealing plate 12. The sealing plate 12 moves along the axial direction of the screw 11 to open and close the glue dispensing channel 17. A knob 15 is provided at the end of the screw 11 that extends to the outside of the glue dispensing box 1. Anti-slip texture 16 is provided on the surface of the knob 15. There are several ball bearing heads 3, which are equidistantly arranged at the bottom of the coating box 1, so that different areas of the fabric can be coated at the same time, improving coating efficiency; the screw 11 on the coating box 1 controls the sealing plate 12 to open and close the glue outlet channel 17, which can flexibly adjust the glue output to adapt to the coating needs of fabrics of different thicknesses and materials, and enhance the versatility of the equipment.

The bottom outer wall of the limiting cylinder 7 is provided with a notch 13 and an arc-shaped layer 14. The height of the notch 13 extends into the interior of the connecting cylinder 301, wherein the arc-shaped layer 14 abuts against the surface of the ball head 304.

[0020] The notch 13 on the bottom outer wall of the limiting cylinder 7 ensures that the adhesive flows smoothly from the adhesive storage chamber 2 through the adhesive outlet channel 17, the adhesive outlet 5, and the opening 302 of the connecting cylinder 301 to the ball head 304. The bonding structure between the arc layer 14 and the ball head 304 guides the adhesive to adhere evenly to the surface of the ball, and with the rolling of the ball, continuous and uniform adhesive application is achieved, improving the bonding strength and stability of the fabric after lamination.

[0021] In this invention, the working steps of the device are as follows: When in use, turn the knob 15: the operator holds the knob 15 with anti-slip texture 16, drives the screw 11 to rotate, and moves the sealing plate 12 along the axial direction of the screw 11 to adjust the opening and closing degree of the glue dispensing channel 17 until the required glue dispensing amount is reached. Start the fabric conveying device: move the fabric to be coated along the preset trajectory to ensure that the area of ​​the fabric to be coated is aligned with the ball bearing heads 3 equidistantly set at the bottom of the coating box 1; when the fabric comes into contact with the ball bearing head 304, the ball bearing head 304 moves upward and applies force to the limiting cylinder 7. With the cooperation of the positioning ring 9, the spring 8 contracts, the top of the limiting cylinder 7 moves upward, the glue outlet 5 and the bottom of the limiting cavity 303 open, and the glue flows to the ball bearing head 304 through the glue outlet channel 17, the glue outlet 5, the opening 302 of the connecting cylinder 301 and the notch 13 at the bottom of the limiting cylinder 7; The ball head 304 rotates as the fabric moves. Guided by the arc layer 14, the adhesive is evenly applied to the surface of the ball head 304 and then spread onto the fabric. After the adhesive is applied, the fabric conveying device is turned off, and the fabric is separated from the ball head 304.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
