Description

Technical Field

[0001] The utility model relates to the technical field of glue spraying equipment, in particular to a high-efficiency glue spraying device. Background Art

[0002] Glue spraying equipment is a machine that automatically sprays glue onto the surface of an object, and can be used to stick different products together. Automatic gluing equipment is a machine used to automatically apply glue or adhesive during the manufacturing process. It uses an external liquid pump to pump the glue in the barrel into the nozzle, and sprays it out of the nozzle and onto the surface of the object.

[0003] During the spraying process of the workpiece, different spraying positions may require different amounts of glue to be sprayed. In this case, if the same nozzle is used, the amount of glue sprayed per unit time from the nozzle outlet is difficult to change. When spraying a large area, the power of the liquid pump can only be increased, otherwise the spraying efficiency will be reduced. Increasing the spraying pressure will easily cause glue splashing. Therefore, it is necessary to replace a nozzle with a larger diameter. Under the original spraying pressure, more glue can be sprayed per unit time. In order to avoid wasting time caused by switching nozzles, it is necessary to design a glue spraying device that can quickly switch nozzles. Utility Model Content

[0004] The utility model aims to provide a high-efficiency glue spraying device in view of the problems existing in the background technology.

[0005] The technical solution of the utility model is as follows: a high-efficiency glue spraying device comprises a spray head and a nozzle mounted on a numerical control slide rail, the numerical control slide rail is slidably connected to a fixed rail, a track plate is fixed on the numerical control slide rail, the spray head is fixed on the track plate, the bottom of the spray head passes through the track plate and is provided with a discharge port, a mounting frame is fixed on the front side of the track plate, a switching plate is rotatably connected to the bottom of the mounting frame, the switching plate is located below the spray head, a group of nozzles are installed on the switching plate and at a position corresponding to the discharge port, wherein the upper end of one of the nozzles abuts against the bottom of the discharge port.

[0006] Preferably, a perforation is provided in the nozzle, and the sizes of the perforations of different nozzles are different. The different sizes of the perforations can make different nozzles spray different amounts of glue per unit time.

[0007] Preferably, a baffle is fixed on the front side of the track plate and above the switching turn plate. During the rotation of the switching turn plate, the baffle can be used to cover the upper openings of the remaining nozzles to prevent dust from falling in.

[0008] Preferably, a sealing gasket is fixed on the upper end of the switching plate and located at the periphery of the nozzle, and the upper end of the seal abuts against the baffle plate. The sealing gasket is used to ensure the sealing of the connection between the baffle plate and the switching plate to avoid the risk of glue overflow.

[0009] Preferably, a servo motor is fixed to the upper end of the mounting frame, and an output end of the servo motor is fixed to the switching plate.

[0010] Preferably, a glue tube is fixed on the nozzle, and a liquid pump is installed on the glue tube, and the glue is pumped into the nozzle by the glue tube and sprayed out from the discharge port.

[0011] Compared with the prior art, the utility model has the following beneficial technical effects: a rotatable switching plate is provided on the nozzle, and by rotating the switching plate, nozzles of different types can be aligned with the discharge outlet at the bottom of the nozzle when selecting different spraying amounts, thereby achieving rapid replacement during the spraying process and improving work efficiency.

[0017] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Example

[0019] like Figure 1-4As shown, the utility model proposes an efficient glue spraying device, including a nozzle 3 and a nozzle 5 installed on a CNC slide rail 12, the CNC slide rail 12 is slidably connected to the fixed rail 1, a track plate 2 is fixed on the CNC slide rail 12, the nozzle 3 is fixed on the track plate 2, the bottom of the nozzle 3 passes through the track plate 2, and a discharge port 31 is opened, a mounting frame 21 is fixed on the front side of the track plate 2, a switching plate 6 is rotatably connected to the bottom of the mounting frame 21, the switching plate 6 is located below the nozzle 3, a group of nozzles 5 are installed on the switching plate 6 and at a position corresponding to the discharge port 31, the upper end of one of the nozzles 5 is against the bottom of the discharge port 31, a glue pipe 4 is fixed on the nozzle 3, and a liquid pump is installed on the glue pipe 4.

[0020] A through hole 51 is provided in the nozzle 5, and the sizes of the through holes 51 of different nozzles 5 are different. A baffle 22 is fixed on the front side of the track plate 2 and above the switching turn plate 6. A sealing gasket 61 is fixed on the upper end of the switching turn plate 6 and outside the nozzle 5, and the upper end of the seal is against the baffle 22. A servo motor 23 is fixed on the upper end of the mounting frame 21, and the output end of the servo motor 23 is fixed on the switching turn plate 6. The output end of the servo motor 23 can be used to drive the switching turn plate 6 to rotate so that the designated nozzle 5 is aligned with the discharge port 31.

[0021] In this embodiment, the entire device is first connected to an external power source, and the glue is pumped into the nozzle 3 by the glue tube 4 and sprayed out from the discharge port 31. During this process, the output end of the servo motor 23 is used to drive the switching plate 6 to rotate so that the specified nozzle 5 is aligned with the discharge port 31. When the spraying pressure remains consistent, the larger diameter perforation 51 will discharge more glue per unit time, which is suitable for large-area glue spraying and effectively improves efficiency. The smaller diameter perforation 51 will discharge less glue per unit time, which is suitable for fine glue spraying in a smaller range. When spraying at different positions on the same workpiece, the spraying mode can be quickly switched, thereby achieving the purpose of improving efficiency, and there is no need to manually switch the nozzle 5. During the rotation of the switching plate 6, the baffle 22 can be used to cover the upper openings of the remaining nozzles 5 to prevent dust from falling in, and the sealing gasket 61 is used to ensure the sealing of the connection between the baffle 22 and the switching plate 6 to avoid the risk of glue overflow.
