[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0026] Some embodiments of this utility model are described below with reference to the accompanying drawings.

[0027] Combination Figure 1-6 As shown, this embodiment provides a two-component dispensing machine, including: a main body 100 and a dispensing mechanism 200.

[0028] The main structure 100 includes a base 110, brackets 120 symmetrically fixed on both sides of the base 110, a gantry frame 130 installed on the top of the base 110, locking members 140 movably sleeved on both sides of the gantry frame 130, a conveying member 150 movably mounted on and passing through the locking member 140, a storage member 160 symmetrically fixed on both sides of the brackets 120, an electric telescopic rod 170 installed on one side of the brackets 120, and an extruder 180 with one end fixed to the end of the electric telescopic rod 170 and the other end extending into the storage member 160.

[0029] The base 110 is used to install the glue dispensing mechanism 200. A groove 111 is opened on one side of the base 110, and the glue dispensing mechanism 200 is fitted into the groove 111, which facilitates the installation and disassembly of the glue dispensing mechanism 200 and increases the ease of replacement of the glue dispensing mechanism 200.

[0030] The bracket 120 is used to fix the storage component 160 and the electric telescopic rod 170. The gantry frame 130 is used to install the locking component 140 and limit the movement of the locking component 140. The locking component 140 includes a movable seat 141 movably disposed on the top of the base 110, a U-shaped frame 142 fixed on the top of the movable seat 141, sleeves 143 symmetrically fixed on both sides of the movable seat 141 and movably sleeved on the gantry frame 130, and one end connected to the top of the sleeve 143 and the other end connected to the gantry. The first spring 144 at the top of the frame 130 and the movable seat 141 are L-shaped and used to lock and limit the glue dispensing mechanism 200 fitted in the groove 111 to ensure the stability of the glue dispensing mechanism 200. The U-shaped frame 142 is used to install the conveyor 150. The sleeve 143 is slidably sleeved on the gantry frame 130 to limit the movement of the movable seat 141. The first spring 144 can keep the movable seat 141 always close to the base 110 to ensure the locking of the glue dispensing mechanism 200.

[0031] The conveying component 150 is used to feed AB glue into the dispensing mechanism 200. It includes a sliding block 151 movably disposed inside the U-shaped frame 142, a round tube 152 symmetrically fixed on both sides of the sliding block 151 and extending through the movable seat 141 into the first glue inlet tube 211 or the second glue inlet tube 212, and a second spring 153 connecting the sliding block 151 and the top of the U-shaped frame 142. The sliding block 151 is used to drive the round tube 152 to move, so that the round tube 152 can be moved out of the dispensing mechanism 200. One end of the round tube 152 is connected to the storage component 160, and the other end extends into the dispensing mechanism 200 to feed glue into the dispensing mechanism 200. The second spring 153 is used to ensure that the sliding block 151 is always pressed against the movable seat 141, that is, to ensure that one end of the round tube 152 is always extended into the dispensing mechanism 200.

[0032] Storage component 160 is used to store AB glue, including a cylinder 161 fixed on bracket 120, a cover plate 162 installed on the top of cylinder 161 by threaded connection, and a hose 163 with one end connected to cover plate 162 and the other end connected to the end of round tube 152. Cylinder 161 is used to store glue, cover plate 162 is used to close cylinder 161 and facilitates subsequent replenishment of glue in the cavity of cylinder 161. One end of hose 163 is connected to the end of round tube 152 and the other end is connected to the cavity of cylinder 161. When electric telescopic rod 170 retracts, it can send the glue in the cavity of cylinder 161 out through hose 163, so that the glue enters the cavity of glue dispensing mechanism 200 through hose 163 and round tube 152.

[0033] The electric telescopic rod 170 is used to drive the extruder 180 to move. The extruder 180 is used to extrude the glue inside the cylinder 161. It includes a connecting rod 181 with one end fixed to the end of the electric telescopic rod 170, a support rod 182 fixed to the other end of the connecting rod 181 and extending into the cylinder 161, and a piston 183 fixed to the end of the support rod 182. The connecting rod 181 connects the end of the electric telescopic rod 170 and the end of the support rod 182 together, so that when the electric telescopic rod 170 extends or retracts, it can drive the support rod 182 to move synchronously. When the support rod 182 moves, it drives the piston 183 to move. The movement of the piston 183 extrudes the glue inside the cylinder 161 outward.

[0034] The glue dispensing mechanism 200 is used to mix and dispense AB glue, and includes a housing 210 fitted onto the base 110, a partition 220 fixed to the inner wall of the housing 210 and dividing the inner cavity of the housing 210 into an upper cavity and a lower cavity, a first glue dispensing tube 230 installed at the bottom of the housing 210 and communicating with the lower cavity, and a second glue dispensing tube 240 installed at the bottom of the partition 220 and extending into the first glue dispensing tube 230.

[0035] The housing 210 is fitted into the groove 111 for easy installation and disassembly. The partition 220 divides the inner cavity of the housing 210 into an upper cavity and a lower cavity, which are used to deliver different types of glue. The first glue outlet tube 230 is connected to the lower cavity and is used to deliver the glue in the lower cavity. The top of the second glue outlet tube 240 is connected to the upper cavity and is used to deliver the glue in the upper cavity. Multiple through holes 241 are arranged in a ring on the outer surface of the second glue outlet tube 240. When the glue enters the second glue outlet tube 240, it can be evenly delivered into the first glue outlet tube 230 through the through holes 241, so that the two types of glue A and B can be mixed evenly in the first glue outlet tube 230.

[0036] In addition, a first glue inlet tube 211 is provided on one side of the inner top wall of the housing 210 to connect to the lower cavity of the housing 210 and to deliver glue B into the lower cavity. A second glue inlet tube 212 is provided on the other side of the inner top wall of the housing 210 to connect to the upper cavity of the housing 210 and to deliver glue A into the upper cavity. At the same time, the round tube 152 extends into the first glue inlet tube 211 and the second glue inlet tube 212.

[0037] The working principle and usage process of this utility model are as follows: When a blockage occurs in the first dispensing tube 230, the locking member 140 is pulled up, causing the conveying member 150 to move upward, so that the round tube 152 is moved out from the first dispensing tube 211 and the second dispensing tube 212. At the same time, the locking of the housing 210 is released, the blocked dispensing mechanism 200 is removed from the groove 111 on the base 110, and a new dispensing mechanism 200 is replaced. Its housing 210 is then inserted into the groove 111 on the base 110. Inside, the locking piece 140 is released. Under the action of the first spring 144, the movable seat 141 moves down, locking the housing 210. At the same time, the conveying piece 150 moves down with the housing 210, and the two round tubes 152 on both sides are inserted into the first glue inlet tube 211 and the second glue inlet tube 212 respectively. When dispensing glue, the two electric telescopic rods 170 on both sides retract synchronously, driving the extruder 180 to move up in the inner cavity of the cylinder 161, and dispensing the A glue and B glue in the inner cavity of the cylinder 161 through the hose 163. During extrusion, adhesive A in one side of the cylinder 161 is fed into the upper cavity of the housing 210 through the hose 163, the round tube 152, and the second inlet tube 212, and then enters the second outlet tube 240 through the upper cavity. Adhesive B in the other side of the cylinder 161 is fed into the lower cavity of the housing 210 through the hose 163, the round tube 152, and the first inlet tube 211, and then enters the first outlet tube 230 through the lower cavity. At this time, adhesive A is evenly fed into the first outlet tube 230 through the through hole 241 on the second outlet tube 240, mixed with adhesive B, and then discharged through the end of the first outlet tube 230, facilitating dispensing operations. Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
