[0002] A luggage, also known as a traveling case or a rolling suitcase, is a box used to carry items when going out. It is one type of luggage. Usually, a luggage is used to place clothes, personal care products, and souvenirs needed during a journey. During the production process of a luggage cover plate, the bonding of the carpet and the substrate is one of the key processes.

[0003] During the production of existing luggage, the process of bonding the carpet and the substrate mostly uses manual or semi-automatic methods for glue spraying.

[0032] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0033] The present utility model provides as Figures 1 to 4A glue spraying device for a suitcase cover plate shown in the figure includes an equipment support 1. At the upper end of the equipment support 1, there is a support top plate 11 fixedly connected. On the upper surface of the support top plate 11, two hydraulic cylinders 12 are fixedly installed. Inside the equipment support 1, there are two positioning mechanisms. The positioning mechanism includes a positioning plate 2, a first motor 23, a transmission gear 24, a first rack 25, a second rack 28, and a clamping plate 211. The upper positioning mechanism and the lower positioning mechanism are symmetrically distributed. At the rear of the lower positioning mechanism, there is a glue spraying mechanism fixedly connected. The upper surface of the upper positioning plate 2 is fixedly connected to the telescopic rods of the two hydraulic cylinders 12. The lower positioning plate 2 is fixedly connected to the equipment support 1. On the upper surface of the lower positioning plate 2, there are four positioning grooves 22. The clamping plates 211 are respectively slidably connected to the four positioning grooves 22. On the upper surface of the lower positioning plate 2, there is a placement plate 21 fixedly connected. The first motor 23 is fixedly installed on the lower surface of the lower positioning plate 2. The transmission gear 24 is fixedly connected to the output end of the first motor 23. There are two sets of the first rack 25 and the second rack 28. The two sets of the first rack 25 are meshed with the front and rear sides of the upper half of the transmission gear 24. The two sets of the second rack 28 are meshed with the left and right sides of the lower half of the transmission gear 24. The ends of the first rack 25 and the second rack 28 are respectively fixedly connected to the four clamping plates 211. On the surface of the first rack 25, there is a first limiting groove 26. Inside the first limiting groove 26, there are two first limiting blocks 27 slidably connected. The first limiting blocks 27 are fixedly connected to the upper and lower inner walls of the positioning plate 2. The two first limiting blocks 27 on the same side are in contact with the side surface of the second rack 28 on the same side. On the surface of the second rack 28, there is a second limiting groove 29. Inside the second limiting groove 29, there are two second limiting blocks 210 slidably connected. The second limiting blocks 210 are fixedly connected to the upper and lower inner walls of the positioning plate 2. The two second limiting blocks 210 on the same side are in contact with the side surface of the first rack 25 on the same side.

[0034] Among them, during the bonding process, the surface blanket is placed on the surface of the lower placement plate 21. The lower positioning mechanism adjusts the position of the surface blanket and limits the four sides of the surface blanket to improve the stability of the surface blanket. Next, the substrate is abutted against the lower surface of the upper placement plate 21. Then, the upper positioning mechanism clamps and fixes the position of the substrate to improve the stability of the substrate. Next, the glue spraying mechanism is used to spray glue on the surface blanket.

[0035] Specifically, the output end of the first motor 23 drives the transmission gear 24 to rotate clockwise. The transmission gear 24 cooperates to drive the two groups of first racks 25 and the second rack 28 to push outwards, causing the clamping plates 211 to slide outwards inside the positioning grooves 22. Then, the surface blanket is placed on the surface of the placement plate 21. Next, the output end of the first motor 23 drives the transmission gear 24 to rotate counterclockwise. The transmission gear 24 cooperates to drive the two groups of first racks 25 and the second rack 28 to retract inwards, thereby driving the multiple groups of clamping plates 211 to move closer inwards, adjusting the position of the surface blanket, and clamping and positioning the four sides of the surface blanket. Similarly, the upper positioning mechanism clamps and fixes the substrate. After the surface blanket is sprayed with glue, the two hydraulic cylinders 12 push the upper positioning mechanism downwards, thereby pushing the substrate downwards to bond and fix the substrate to the surface blanket.

[0036] Refer to Figure 5 and Figure 6 As shown in FIGS. 7 and 8, the glue spraying mechanism includes an equipment box 3, a second motor 31, a sliding groove 32, a transmission screw 33, a transmission block 34, a mounting bracket 35, a cylinder 36, and a glue spraying head 37. The equipment box 3 is fixedly connected to the rear end of the lower positioning plate 2. The second motor 31 is fixedly installed at the right end of the equipment box 3. The two ends of the transmission screw 33 are rotatably connected to the left and right inner walls of the equipment box 3. The right end of the transmission screw 33 penetrates the right wall of the equipment box 3 and is fixedly connected to the output end of the second motor 31. The sliding groove 32 is opened on the upper surface of the equipment box 3. The mounting bracket 35 is slidably connected to the sliding groove 32. The transmission block 34 is threadedly connected to the transmission screw 33. The lower end of the mounting bracket 35 is fixedly connected to the upper surface of the transmission block 34. The cylinder 36 is fixedly installed at the upper end of the mounting bracket 35. The glue spraying head 37 is fixedly connected to the front end of the telescopic rod in the cylinder 36.

[0037] In addition, during the process of spraying glue on the surface blanket, the output end of the second motor 31 drives the transmission screw 33 to rotate. The transmission screw 33 drives the transmission block 34 to slide inside the equipment box 3, thereby driving the mounting bracket 35 to slide inside, adjusting the position of the mounting bracket 35 left and right, and then driving the glue spraying head 37 to move left and right. At the same time, the cylinder 36 pushes the glue spraying head 37 back and forth, improving the flexibility of the glue spraying head 37, facilitating its flexible adjustment, thereby effectively improving the glue spraying accuracy and simultaneously increasing the automation degree of the glue spraying mechanism.

[0038] Working principle of the utility model: The second motor 31 drives the transmission screw 33 to rotate, and the transmission screw 33 drives the mounting bracket 35 to slide left and right, so as to adjust the position of the glue spraying head 37 left and right. The telescopic rod in the cylinder 36 drives the glue spraying head 37 to adjust back and forth, improving the flexibility of the glue spraying head 37, facilitating its flexible adjustment, thus effectively improving the glue spraying precision and at the same time increasing the automation degree of the glue spraying mechanism; Meanwhile, the first motor 23 drives the four groups of clamping plates 211 to slide inside the positioning groove 22, respectively positioning the substrate and the surface blanket on the upper and lower sides, making the surface blanket and the substrate at the center of the equipment, and improving their stability during the processing, thus effectively improving the stability during the bonding process of the substrate and the surface blanket and improving the bonding precision.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the utility model and are not used to limit the utility model.
