Description

Technical Field

[0001] The invention relates to the technical field of glue dispensing equipment, and in particular to a glue dispensing machine and a glue dispensing method thereof. Background Art

[0002] In the process of garment manufacturing, some iron-free seams are usually glued so that the shape and lines of the garment can be maintained under the action of glue, and no frequent ironing is required, such as the lines in the middle of the legs of trousers. In the existing technology, glue is dispensed manually, which is inefficient, and the glue amount and speed cannot be accurately controlled, making it difficult to ensure product quality. Summary of the invention

[0003] In order to solve the problems in the prior art of low manual glue dispensing efficiency and difficulty in ensuring product quality, the present invention provides a glue dispensing machine and a glue dispensing method thereof with high efficiency and guaranteed quality.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] A glue dispensing machine comprises a frame, a workbench is arranged on the frame, a crossbeam is spanned above the workbench, a trolley is arranged on the crossbeam and a lifting pressure wheel is arranged on the trolley, a groove and an air suction hole are arranged on the surface of the workbench, the pressure wheel presses the cloth to be glued into the groove, adsorption holes for adsorbing the cloth are arranged on both sides of the groove on the surface of the workbench, and a liftable glue dispensing device for dispensing glue to the cloth in the groove is arranged on the trolley beside the pressure wheel.

[0006] Furthermore, a workstation is respectively arranged on both sides of the workbench, and the crossbeam reciprocates between the two workstations.

[0007] Furthermore, a vacuum adsorption device communicating with the adsorption hole is provided in the workbench.

[0008] Furthermore, the outer edge of the pressing wheel matches the shape of the groove.

[0009] Furthermore, the groove is a V-shaped groove or a U-shaped groove.

[0010] Furthermore, a first cylinder and a second cylinder are fixed on the trolley, the pressure wheel is fixed to the end of the piston rod of the first cylinder, and the dispensing device is fixed to the end of the piston rod of the second cylinder.

[0011] Furthermore, the dispensing device includes a rubber hose and a back-suction dispensing valve that are interconnected.

[0012] Furthermore, the crossbeam is provided with a first proximity switch for detecting that the trolley is in place, and the frame is provided with a second proximity switch for detecting that the crossbeam has moved into place.

[0013] A dispensing method for the dispensing machine as described above comprises the following steps:

[0014] Step 1: Spread the fabric on the workbench, flatten the fabric, keep it flat through the adsorption holes, and align the part of the fabric to be glued with the groove position;

[0015] Step 2: The piston rod of the first cylinder extends, the pressing wheel descends, and then the trolley slides from one end of the workbench to the other end. During the sliding process, the pressing wheel presses the fabric into the groove;

[0016] Step 3: When the trolley reaches the first proximity switch position, the first cylinder piston rod drives the pressure wheel to retract, and the second piston rod extends. At the same time, the trolley slides back. During the sliding process, the dispensing equipment dispenses glue to the fabric in the groove. After the dispensing is completed, the back-suction dispensing valve stops dispensing glue. At the same time, the second piston rod drives the dispensing equipment to retract.

[0017] Beneficial effects:

[0018] (1) The dispensing machine of the present invention replaces the traditional manual dispensing work, solving the problems of low efficiency and poor product consistency;

[0019] (2) The fabric is pressed into the V-shaped groove by the V-shaped edge of the pressing wheel, so that the fabric forms a V-shaped accommodation space, and then glue is applied, which has a good shaping effect and is more beautiful;

[0020] (3) There are two workstations on a workbench, and the crossbeam reciprocates between the two workstations, so that one workstation can lay the fabric and the other workstation can dispense glue, and then they can alternate, which is highly efficient;

[0021] (4) The dispensing equipment adopts a back-suction dispensing valve, which can effectively control the dispensing and stop of glue, and has high controllability. BRIEF DESCRIPTION OF THE DRAWINGS
