[0002] During the label production process, it is generally necessary to apply adhesive to the label surface to protect it.

[0003] However, in the existing dispensing equipment, the labels unwound from the roll are prone to undulation and misalignment during the dispensing process, and the backing paper and face paper cannot be pressed tightly together, resulting in poor adhesion and reduced production quality. Utility Model Content

[0004] To address the problems of existing dispensing equipment where labels unloaded from the roll tend to wobble and shift during the dispensing process, and where the backing paper and face paper cannot be pressed tightly together, resulting in poor adhesion and reduced production quality, this application provides a dispensing device for label production.

[0005] This application provides a dispensing device for label production, which adopts the following technical solution:

[0006] A dispensing device for label production includes a dispensing housing, with symmetrically arranged support frames at the bottom of the dispensing housing. A conveying roller and a take-up roller are rotatably mounted on the top of the two support frames, respectively. A label tape is wound between the conveying roller and the take-up roller. A first positioning component is symmetrically arranged inside the dispensing housing between the conveying roller and the take-up roller, and a support roller is symmetrically mounted between the two first positioning components. The label tape passes through the positioning mechanism, and an adhesive application mechanism is mounted on the top of the dispensing housing.

[0007] Preferably, the first positioning component includes a support base fixed to the inner wall of the dispensing housing. The support base has symmetrically formed grooves on its outer side, and each groove is provided with a positioning slide rod. A slider and a first spring are respectively sleeved on the outer side of the positioning slide rod. The other end of the first spring is fixedly connected to the slider. A pressure roller is installed on the outer side of the slider.

[0008] Preferably, the adhesive application mechanism includes a storage tank fixed to the top of the adhesive application housing, a corrugated pipe installed on one side of the storage tank, an adhesive application pipe fixedly connected to the corrugated pipe, and an adhesive dispensing machine installed at the bottom of the adhesive application pipe. The end of the corrugated pipe away from the storage tank extends into the adhesive application housing and is fixedly connected to the adhesive application pipe.

[0009] Preferably, an electric cylinder is installed at the top center of the dispensing housing, and the output shaft end of the electric cylinder extends through the dispensing housing and is provided with a fixing plate.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0018] Please see Figures 1 to 3 This utility model provides a technical solution:

[0019] A dispensing device for label production includes a dispensing housing 1. Support frames 2 are symmetrically arranged at the bottom of the dispensing housing 1. A conveying roller 3 and a take-up roller 4 are rotatably mounted on the top of the two support frames 2, respectively. A label tape 5 is wound between the conveying roller 3 and the take-up roller 4. First positioning components are symmetrically arranged inside the dispensing housing 1 between the conveying roller 3 and the take-up roller 4, and support rollers 6 are symmetrically installed between the two first positioning components. The label tape 5 passes through the positioning mechanism. A glue application mechanism is installed on the top of the dispensing housing 1.

[0020] In use, first, wrap the label tape 5 around the conveyor roller 3, then fix the other end of the label tape 5 around the take-up roller 4. Start the servo motor that drives the take-up roller 4 to rotate, thereby realizing the automatic winding and conveying of the label tape 5. The label tape 5 is pressed by the first positioning component set on the left, so that the label can be tightly attached to the label tape 5, avoiding affecting the accuracy of the glue dispensing. When the label tape 5 passes under the glue dispensing mechanism for glue dispensing, it passes by the first positioning component set on the left. The first positioning component smooths the glue, so that the glue can be better and more evenly applied to the label, improving the quality of glue dispensing.

[0021] The first positioning component includes a support base 7 fixed to the inner wall of the dispensing housing 1. The support base 7 has symmetrically opened grooves on its outer side, and each groove is provided with a positioning slide rod 8. A slider 9 and a first spring 10 are respectively sleeved on the outer side of the positioning slide rod 8. The other end of the first spring 10 is fixedly connected to the slider 9. A pressure roller 11 is installed on the outer side of the slider 9. In use, the label tape 5 will pass between the two pressure rollers 11. After the two pressure rollers 11 are squeezed, they will drive the slider 9 to move on the positioning slide rod 8, and at the same time squeeze the first spring 10. At the same time, the label tape will also be subjected to the reverse squeezing force of the first spring 10, thereby achieving the purpose of pressing.

[0022] The glue application mechanism includes a storage tank 12 fixed to the top of the glue application housing 1, a corrugated pipe installed on one side of the storage tank 12, a glue application pipe 15 fixedly connected to the corrugated pipe, and a glue dispensing machine 13 installed at the bottom of the glue application pipe 15. The end of the corrugated pipe away from the storage tank 12 passes through the glue application housing 1 and is fixedly connected to the glue application pipe 15. The glue in the storage tank 12 reaches the glue dispensing machine 13 through the corrugated pipe and the glue application pipe 15, and the glue dispensing machine 13 performs glue application on the label.

[0023] An electric cylinder 14 is installed at the top center of the dispensing housing 1. The output shaft end of the electric cylinder 14 passes through the dispensing housing 1 and is provided with a fixing plate 16. The glue application tube 15 is fixed on the outside of the fixing plate 16. Second positioning components are symmetrically arranged on both sides of the fixing plate 16.

[0024] The second positioning component includes a connecting rod 17 fixedly connected to the fixed plate 16, a movable rod 18 slidably sleeved inside the connecting rod 17, and a positioning roller 19 installed at one end of the movable rod 18. One end of the movable rod 18 passes through the connecting rod 17 and is fixedly connected to a second spring 20, while the other end passes through the connecting rod 17 and is installed with the positioning roller 19.

[0025] During operation, the electric cylinder 14 can be activated to lift and lower the fixing plate 16, the glue applicator tube 15, and the glue dispensing machine 13 to dispense glue onto the label. When the glue applicator tube 15 and the glue dispensing machine 13 move towards the label tape 5, the positioning roller 19 will first contact the label tape 5. With the cooperation of the support roller 6, the label tape 5 will be positioned again to prevent displacement during the glue dispensing process. When it continues to move downward, the connecting rod 17 will squeeze the second spring 20 to buffer the pressure and prevent excessive pressure from damaging the label tape 5 until the glue dispensing machine 13 contacts the label to dispense glue.
