Description

Technical Field

[0001] The utility model relates to the technical field of latex fabric garment making, in particular to a position limiting, aligning and bonding device for latex elastic fabric. Background Art

[0002] Latex clothing is made from latex and is primarily used in various industries, including fitness, swimming, tights, lingerie, and film. Latex clothing is made from latex fabric (also known as latex sheet or film). Unlike other clothing fabrics, latex clothing must be glued together at all cut and joined points, then heat-pressed to prevent delamination during wear.

[0003] Existing techniques typically involve manual gluing, alignment, and bonding, resulting in low efficiency, poor precision, and extremely high operator requirements and reliance on personnel. The production of latex garments requires overlapping and bonding latex sheets of varying shapes. The bonding process must ensure uniform seam widths, and the two pieces must not stretch during bonding, otherwise they will be uneven in length. Latex fabric is elastic, requiring specialized glue for assembly. Furthermore, it is prone to deformation and expansion after gluing, making manual alignment and bonding difficult to ensure precision. Furthermore, certain areas of the garment, such as the shoulders and chest, often feature curved sections, further increasing the complexity and demands placed on the operator. Utility Model Content

[0004] The main purpose of the utility model is to provide a latex elastic fabric limiting alignment bonding device to solve the above problems.

[0005] To achieve the above-mentioned purpose, the utility model provides a limiting alignment and bonding device for latex elastic fabrics, comprising an integral bracket, a lifting mechanism, an upper head assembly, a lower head assembly and a glue-isolating needle cantilever; the lifting mechanism is mounted on the top of the integral bracket, the upper head assembly is mounted on the output end of the lifting mechanism, and the lower head assembly is mounted on the bottom of the integral bracket and arranged opposite to the upper head assembly; the glue-isolating needle cantilever is rotatably arranged on the top of the integral bracket; a glue-isolating needle is arranged at the bottom of the glue-isolating needle cantilever; limiting grooves are provided on the facing sides of the upper head assembly and the limiting grooves are adapted to the EVA strips, a first driving wheel is rotatably provided in the limiting groove of the upper head assembly, and a second driving wheel is rotatably provided in the limiting groove of the lower head assembly, the first driving wheel and the second driving wheel are of the same model, the same speed, and opposite rotation directions, and the first driving wheel and the second driving wheel are both used to drive the EVA strips to move.

[0006] Furthermore, the upper head assembly is connected to the lifting mechanism through a connecting plate, a first motor is installed on the connecting plate, and a first driving wheel is installed on the first motor; a first driven wheel is rotatably arranged in the upper head assembly, the first driving wheel is installed on the first driven wheel, and the first driving wheel and the first driven wheel are connected by a first synchronous belt.

[0027] Before the bonding process, first prepare the two pieces of latex elastic fabrics 100 that need to be bonded, lay them flat on the workbench, then prepare an EVA adhesive strip 300 that is the same length as the bonding edge of the latex elastic fabric 100, align the EVA adhesive strip 300 with the bonding edge of the latex elastic fabric 100 and stick it on one side of the bonding edge. After both pieces of latex elastic fabric 100 are pasted with the EVA adhesive strip 300, turn them over and apply glue 200 to the other side of the bonding edge. During the bonding process, first lift the upper machine head assembly 5 through the lifting mechanism 3, manually rotate the glue needle cantilever 6 upward, then place one of the latex elastic fabrics 100 with the glued surface facing up, and insert one end of the EVA adhesive strip 300 into the limiting groove 56 of the lower machine head assembly 7; then rotate the glue needle cantilever 6 downward to push the glue needle 61 onto the glue surface of the lower latex elastic fabric 100; then place the other piece of latex elastic fabric 100 with the glued surface facing down, and insert one end into the lower machine head together with the lower latex elastic fabric 100. One end of the assembly 7 is aligned and pre-pasted; the upper head assembly 5 is pressed down by the lifting mechanism 3, so that the EVA strip 300 on the upper latex elastic fabric 100 is embedded in the limit groove 56 of the upper head assembly 5, and the first driving wheel 53 and the second driving wheel 73 are started to make the upper and lower pieces of latex elastic fabric 100 move forward synchronously.
