Description

Technical Field

[0001] This utility model relates to the technical field of glue supply equipment, specifically a pneumatic pressurized glue supply device. Background Technology

[0002] In the field of mechanical equipment, glue is sprayed by a dispensing device. The dispensing device supplies glue to multiple dispensing devices through a glue container. The glue container stores glue inside. The nozzle connected to the dispensing device extends into the bottom of the glue container, and the glue is delivered from the glue container to the dispensing device.

[0003] However, existing glue supply devices still have some problems in use:

[0004] For example, a glue supply device with application number CN201720939493.4 includes a glue bucket containing glue. The glue bucket includes a bucket body and an inverted conical part that communicates with the bucket body and is located below the bucket body. The device is characterized in that: the glue supply device also includes a sealing bucket and a glue outlet pipe. The glue bucket is contained in the sealing bucket, and the inverted conical part is located at the bottom of the sealing bucket. An air inlet pipe is provided on the sealing bucket and communicates with the inside of the sealing bucket. A through hole is provided on the top of the glue bucket, and the glue outlet pipe is inserted into the sealing bucket and communicates with the inside of the glue bucket through the through hole. The through hole connects the sealing bucket and the glue bucket.

[0005] Because the adhesive has a certain viscosity, some adhesive will adhere to the inner wall of the glue container during the glue supply process. If it is not cleaned in time, the adhesive will solidify inside the glue container, which will affect the flowability of the adhesive and easily lead to uneven glue supply. This will seriously affect the product quality, adhesive performance and use effect.

[0006] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0007] To address the aforementioned issues, an innovative design was implemented based on the existing glue supply device. Utility Model Content

[0008] The purpose of this utility model is to provide a pneumatic pressurized glue supply device to solve the problem mentioned in the background art that, due to the viscosity of the glue, some glue will adhere to the inner wall of the glue bucket during the glue supply process. If it is not cleaned in time, the glue will solidify inside the glue bucket, thereby affecting the fluidity of the glue and easily causing uneven glue supply, which will seriously affect product quality, glue performance and use effect.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A pneumatic pressurized glue supply device includes a glue storage tank, a controller, an air inlet pipe, and a pressure regulating valve. The controller is fixedly installed on one side of the glue storage tank, and the air inlet pipe is connected to the top of the glue storage tank. The pressure regulating valve is installed in the middle of the air inlet pipe.

[0011] The upper end of the glue storage tank is fitted with a top cover, and a motor is fixed to the upper end of the top cover. The output end of the motor is rotatably connected to a drive shaft inside the glue storage tank. A fixing frame is fixed to the outer surface of the drive shaft, and a scraper is fixed to the top of the fixing frame. An electric heating wire is embedded inside the glue storage tank.

[0012] Preferably, the fixing frame and scraper are evenly distributed in three sets along the outer surface of the drive shaft, and the outer edge of the scraper is in close contact with the inner wall of the glue storage tank.

[0013] By adopting the above technical solution, the motor drives the transmission shaft to rotate, causing the fixing frame and scraper to rotate accordingly. The scraper adheres to the inner wall of the glue storage tank and scrapes off the adhering glue, preventing the glue from curing and affecting its fluidity, and ensuring uniform glue supply. At the same time, the heating wire embedded in the glue storage tank can heat the glue, further improving the glue performance, enhancing the use effect, improving the glue fluidity, ensuring the stability of glue supply, and thus improving product quality.

[0014] Preferably, the heating wires are arranged in a ring shape along the inside of the glue storage tank and are distributed longitudinally.

[0015] By adopting the above technical solution, the heating wire is designed in a ring shape inside the glue storage tank, which can increase the heating area of ​​the glue, maintain the fluidity of the glue, and ensure the stability of glue supply.

[0016] Preferably, the bottom edge of the glue storage tank is threaded with four sets of studs, the outer surface of the studs is nested with nuts, and the bottom end of the studs is fixed with feet.

[0017] By adopting the above technical solution, the length of the studs extending out of the bottom edge of the glue storage tank can be adjusted by rotating the nut. This allows the height and level of the glue storage tank to be adjusted by adjusting the four sets of studs according to the actual installation scenario and level requirements, so that the glue storage tank can be placed stably and the glue supply device can operate normally.

[0018] Preferably, a glue outlet pipe is connected to one side of the glue storage tank, a filter is connected to the middle of the glue outlet pipe, and a regulating valve is provided in the middle of the glue outlet pipe.

[0019] By adopting the above technical solution, by installing a filter on the dispensing pipe, impurities in the glue can be physically filtered out, ensuring the purity of the dispensing liquid and preventing impurities from clogging subsequent equipment or affecting the dispensing quality; the regulating valve can flexibly adjust the dispensing volume according to actual dispensing needs, ensuring the accuracy and stability of glue supply.

[0020] Preferably, a fixing seat is welded to the outer surface of the glue storage tank, a screw is rotatably connected to the middle of the fixing seat, a retaining plate corresponding to the fixing seat is welded to the outer surface of the top cover, and the screw and the retaining plate are engaged, and a nut is nested on the outer surface of the screw.

[0021] By adopting the above technical solution, the screw is rotated to engage or disengage with the card plate. When the nut is tightened, the position of the screw can be fixed, thereby realizing the quick connection and separation between the top cover and the glue storage tank. This facilitates the cleaning and maintenance of the inside of the glue storage tank, while ensuring the firmness of the connection and preventing the top cover from loosening and affecting the operation of the device during glue supply.

[0022] Preferably, the outer surface of the top cover is connected to an injection tube, a hinge seat is fixed on one side of the injection tube, a sealing cover plate is rotatably connected to the upper end face of the injection tube through the hinge seat, a spring fastening bolt that is threadedly connected to the injection tube is provided on one side of the sealing cover plate, and a sealing rubber ring is pasted on the bottom of the sealing cover plate.

[0023] By adopting the above technical solution, the sealing cover can rotate around the glue injection tube through the hinge seat. The sealing cover is tightened by the threaded connection between the spring fastening bolt and the glue injection tube, and the sealing ring at the bottom achieves a seal. This allows the sealing cover to be opened when glue is injected into the glue storage tank. After the glue is injected, the glue injection tube can be effectively sealed to prevent glue leakage and the entry of external impurities, thus ensuring the quality of the glue in the glue storage tank and the normal operation of the glue supply device.

[0024] Compared with the prior art, the beneficial effects of this utility model are: this pneumatic pressurized glue supply device,

[0025] 1. The motor drives the drive shaft to rotate, which in turn drives the fixed frame and scraper fixed on its outer surface to rotate. The outer edge of the scraper is in contact with the inner wall of the glue storage tank so as to scrape off the glue adhering to the inner wall of the glue storage tank, thereby preventing the glue from curing and affecting its fluidity, and ensuring uniform glue supply.

[0026] 2. By embedding a ring-shaped heating wire inside the glue storage tank, the heating wire can heat the glue. The wire is arranged longitudinally, which can increase the heating area of ​​the glue, further improve the glue performance, enhance the application effect, improve the glue fluidity, ensure glue supply stability, and thus improve product quality.

[0027] 3. By manually adjusting the length of the studs extending from the bottom edge of the glue storage tank, and then using nuts to tighten the studs to the bottom edge of the glue storage tank, the height and level of the glue storage tank can be adjusted by adjusting four sets of studs according to the actual installation scenario and level requirements, so that the glue storage tank is placed stably and the glue supply device is operating normally.

[0028] 4. By installing a filter in the dispensing tube, the filter adopts a filter screen design, which can physically intercept and filter out impurities in the glue, ensuring the purity of the dispensing glue and preventing impurities from clogging subsequent equipment or affecting the dispensing quality.

[0029] 5. Rotate the sealing cover plate through the hinge seat, and tighten the sealing cover plate by using the spring fastening bolt and the threaded connection of the glue injection tube.
