Description

Technical Field

[0001] This utility model relates to the technical field of glue supply mechanism for dispensing machines, specifically a glue supply mechanism for dispensing machines. Background Technology

[0002] The glue supply mechanism is an important component of the dispensing machine during operation. It is mainly used to store glue and accurately deliver the glue to the dispensing head according to the dispensing settings, thereby improving the stability and accuracy of the dispensing machine. However, if it is inconvenient to consistently add glue according to the usage situation, it can easily affect the working efficiency of the dispensing machine.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application CN202221605473.0, filed on 2022-06-25) provides an automatic glue supply mechanism for a dispensing machine. This mechanism uses a motor to drive a motor shaft, which, in conjunction with a clamping component, causes a protruding extrusion component in front of the motor shaft to periodically squeeze the glue tube as the motor shaft rotates. This generates fluid that flows sequentially in the same direction within the glue tube, thus achieving the purpose of glue supply. The glue tube is a disposable product and can be replaced after a period of use. By connecting the glue storage component and the dispensing head to both ends of the glue tube, only the dispensing head needs to be installed at the dispensing station, reducing the space required for installing the dispensing machine. Furthermore, the multiple evenly arranged protruding extrusion components can evenly deliver the glue material from the glue tube to the dispensing head. While the prior art can supply glue, it is inconvenient to remove air bubbles inside the glue during operation, which can easily lead to a low dispensing yield and glue leakage.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on the existing glue supply mechanism of dispensing machines. Utility Model Content

[0005] The purpose of this invention is to provide a glue supply mechanism for a dispensing machine, so as to solve the problem mentioned in the background art that it is inconvenient to remove air bubbles inside the glue during the working process, which easily leads to low dispensing yield and glue leakage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a glue supply mechanism for a dispensing machine, comprising a dispensing machine frame for working support; including: a settling tank, installed on the upper end of the dispensing machine frame, with a connecting rod rotatably connected to the outer surface of the settling tank, and a cover nested on the outer surface of the connecting rod, with a locking nut threadedly connected to the upper end of the outer surface of the connecting rod, and a feed valve installed on the upper surface of the cover; a protective chamber, installed on the upper end of the dispensing machine frame, located behind the outer surface of the settling tank, with a slot formed on the outer surface of the protective chamber, and a fixing plate installed on the upper end of the inner surface of the protective chamber, with a cylinder installed on the outer surface of the fixing plate, and a telescopic rod telescopically connected to the inner surface of the cylinder, the telescopic rod passing through the fixing plate, and a movable plate installed on the upper surface of the telescopic rod.

[0007] Preferably, the settling tank and the dispensing machine frame form an integrated structure, and the settling tank and the cover form a locking structure through a connecting rod and a locking nut, and the cover and the lower surface of the feed valve are embedded in the settling tank.

[0008] The above structure controls the stability of the assembled lid of the static tank during use.

[0009] Preferably, a discharge valve is installed on the lower side of the outer surface of the settling tank, and a buffer chamber is nested on the outer surface of the discharge valve. At the same time, a glue tank is connected to the outer surface of the buffer chamber through a pipe.

[0010] With the above structure, the discharge valve can be stably connected during use, and it can be used in conjunction with the buffer tank for subsequent material filling.

[0014] With the above structure, the position of the moving plate can be controlled in telescopic movement during use, and the stability of the moving plate's telescopic movement is improved through symmetrical cylinders.

[0015] Preferably, a glue container is installed in the middle section of the inner surface of the fixing plate, and a piston block is telescopically connected to the inner surface of the glue container. A sealing ring is connected between the piston block and the glue container, and the sealing ring is nested in the inner surface of the piston block. At the same time, a piston rod is nested in the upper surface of the piston block, and a positioning screw is connected between the piston rod and the piston block. A glue dispensing valve is installed on the upper surface of the piston rod, and a movable plate is installed on the upper side of the outer surface of the piston rod.

[0016] With the above structure, the discharge valve of the piston rod assembly can be effectively adjusted during use to form glue discharge, improving discharge stability and the stability of glue delivery by the dispensing machine.

[0017] Preferably, the fixing plate and the glue tank form an integrated structure, and the glue tank and the piston block form a sealed telescopic structure through the sealing ring, and the piston block and the piston rod form a threaded connection structure through the positioning screw. At the same time, the inner surfaces of the positioning screw and the piston rod are hollow structures, and the piston rod and the lower surface of the glue dispensing valve are embedded in the installation.

Furthermore, the telescopic rod assembled with the moving plate, and the piston rod installed in conjunction with the moving plate, effectively and evenly control the piston rod's extension and retraction via the cylinders, improving the stability of glue extraction and supply. Furthermore, the piston block and sealing ring assembled with the glue canister prevent glue leakage during extraction and supply. The positioning screw assembled with the piston block and piston rod effectively delivers glue, and the hollow design of the piston rod and positioning screw, along with the ball valve structure of the glue dispensing valve, controls the stability of glue dispensing.
