It is mainly used to accurately control the output of fluids (such as glue, grease, adhesives, etc.) to achieve non-contact high-speed and high-precision dispensing operations. Compared with traditional contact dispensing valves, the advantage of the jet valve is that it can avoid damage to the product surface caused by needle contact, while reducing dripping and drawing, and is particularly suitable for high-precision and high-speed production scenarios.

The utility model can improve the glue dispensing quality and stability of the glue dispenser.

[0004] Although the jet valve of the glue dispensing machine can achieve stable glue feeding, the use of the motor and screw for glue feeding operation requires continuous consumption of a certain amount of electricity, which is still not optimized and there is room for improvement. Utility Model Content

[0005] In response to the shortcomings of the prior art, the present application provides an energy-saving glue dispensing machine jet valve, which has the advantages of being able to complete the glue feeding operation during the needle dispensing operation, avoiding the use of motors, and saving electricity resources. It solves the problem that although the existing glue dispensing machine jet valve can achieve stable glue feeding, the use of motors and screws for glue feeding operations requires continuous consumption of a certain amount of electricity, which is still not optimized and there is room for improvement.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: an energy-saving glue dispensing machine injection valve, comprising a main body, a glue storage tank is fixedly connected to the left side of the main body, a firing pin is slidably inserted inside the main body, a nozzle is fixedly connected to the inside of the main body, a slide rod 1 is slidably inserted inside the main body, a fixed plate is fixedly connected to the upper surface of the main body, an electric push rod is fixedly connected to the left side of the fixed plate, and the bottom surface of the electric push rod is fixedly connected to the upper surface of the slide rod 1.

[0007] Through the above scheme, although the existing dispensing machine injection valve can achieve stable glue feeding, the use of motors and screws for glue feeding operations requires continuous consumption of a certain amount of electricity, which is still not optimized enough and there is room for improvement. The sliding rod drives the connecting plate and the inclined plate to move at the same time during the lifting process, so that the striker and the baffle can operate alternately, and when the striker rises, the glue is sucked into the nozzle with the help of the pressure generated by the internal closure of the main body to complete the automatic glue feeding, avoid the use of motors to complete the glue feeding operation, and optimize the glue feeding operation process of the dispensing machine injection valve.

[0008] Furthermore, a connecting plate is fixedly sleeved on the outer circumferential surface of the sliding rod 1, and the other end of the connecting plate is slidably sleeved on the striker through a groove provided on the outer circumferential surface of the striker.

[0009] Through the above scheme, the linkage between the slide rod 1 and the striker is achieved through the connecting plate, and the linkage between the slide rod 1 and the striker has a certain hysteresis under the action of the striker groove.

[0011] Through the above scheme, the nozzle is shielded by the baffle, so that the interior of the body is in a sealed state, which enables the striker to automatically suck the glue into the nozzle when it is lifted, thereby realizing automatic glue feeding.

[0012] Furthermore, an inclined plate is fixedly connected to the upper surface of the baffle, the upper surface of the inclined plate is an inclined surface, and the inclined plate is located below the first sliding rod.

[0013] Through the above scheme, when the sliding rod moves down, the baffle can be driven to move to one side and open under the action of the inclined plate, so that the striker can perform the dispensing operation.

[0016] Furthermore, the inner wall of the fixing seat is fixedly connected with a limiting plate, a limiting groove is arranged inside the second sliding rod, and the second sliding rod is slidably connected with the limiting plate through the limiting groove.

[0017] Through the above solution, the second slide bar is restricted to prevent the second slide bar from rotating, thereby increasing the stability of the movement of the second slide bar.

[0018] Furthermore, a fixing ring is fixedly sleeved on the outer circumferential surface of the second slide rod, a spring is fixedly connected to the left side of the fixing ring, and the other end of the spring is fixedly connected to the right side of the fixing seat.

[0019] Through the above solution, the sliding rod 2 is pushed back by the elastic force of the spring itself, so that the baffle can automatically move back.

[0020] Furthermore, a connecting pipe is fixedly inserted into the interior of the main body, one end of the connecting pipe is fixedly inserted into the interior of the glue storage tank, and the other end of the connecting pipe is fixedly inserted into the interior of the nozzle.

[0021] Through the above solution, the glue storage tank and the nozzle are connected through the connecting pipe, so that the glue can be transported from the glue storage tank into the nozzle.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] The energy-saving glue dispensing machine injection valve drives the connecting plate and the inclined plate to move simultaneously during the lifting and lowering process through a sliding rod, so that the striker and the baffle can operate alternately, and when the striker rises, the glue is sucked into the nozzle with the help of the pressure generated by the internal closure of the main body, thereby achieving the effect of being able to complete automatic glue feeding, avoiding the use of a motor to complete the glue feeding operation, and optimizing the glue feeding operation process of the glue dispensing machine injection valve. The existing glue dispensing machine injection valve can achieve stable glue feeding, but the use of a motor and a screw for the glue feeding operation requires continuous consumption of a certain amount of electricity, is still not optimized enough, and has a certain amount of room for improvement.

[0033] See also Figure 2 , Figure 3 and Figure 4 The bottom surface of the main body 1 is fixedly connected with a fixing seat 10, and a sliding rod 11 is slidably inserted inside the fixing seat 10. The left side of the sliding rod 11 is fixedly connected with a baffle 12. The upper surface of the baffle 12 contacts the bottom surface of the nozzle 4. The baffle 12 blocks the nozzle 4, so that the inside of the main body 1 is in a sealed state, so that the striker 3 can automatically suck the glue into the nozzle 4 when it is lifted, thereby realizing automatic glue feeding.

[0035] See also Figure 2 and Figure 4A through hole 14 is provided inside the baffle 12 and is located on one side of the inclined plate 13. The through hole 14 is in close contact with the inclined plate 13, so that the striker 3 can continue to move downward after moving to the bottom of the inclined surface of the inclined plate 13, thereby avoiding obstruction to the movement of the striker 3.

[0039] An energy-saving glue dispensing machine injection valve in the present embodiment drives the connecting plate 9 and the inclined plate 13 to move simultaneously during the lifting and lowering process through the sliding rod 6, so that the firing pin 3 and the baffle 12 can operate alternately, and when the firing pin 3 rises, the glue is sucked into the nozzle 4 with the help of the pressure generated by the internal closure of the main body 1, so as to achieve the effect of completing automatic glue feeding, avoiding the use of a motor to complete the glue feeding operation, and optimizing the glue feeding operation process of the glue dispensing machine injection valve, and solves the problem that although the existing glue dispensing machine injection valve can achieve stable glue feeding, the use of a motor and a screw for the glue feeding operation requires continuous consumption of a certain amount of electricity, is still not optimized enough, and there is a certain room for improvement.

[0040] It should be noted that the bottom surface of the striker 3 is a plane, and the flat bottom surface can ensure the uniformity of the impact pressure and optimize the dispensing effect.

[0041] The working principle of the above embodiment is:

[0042] When it is necessary to perform glue dispensing, glue is injected into the glue storage tank 2, and the electric push rod 8 is started to drive the slide bar 6 to reciprocate and lift. The slide bar 6 drives the striker 3 to reciprocate and lift through the connecting plate 9, and the groove on the outer circumferential surface of the striker 3 causes the lifting and lowering movement of the striker 3 to have a certain hysteresis. When the slide bar 6 moves down, it will first drive the baffle 12 to follow the slide bar 2 11 to move to one side and open through the inclined plate 13. Then, the slide bar 6 drives the striker 3 to move down under the action of the connecting plate 9, and sprays the glue inside the nozzle 4 to the outside to perform glue dispensing. In the process of the baffle 12 driving the slide bar 2 11 to move, the spring 18 will be stretched. When the slide bar 6 moves up, the spring 18 drives the baffle 12 to automatically return to the original position by its own elastic force. The nozzle 4 is blocked, causing the interior of the body 1 to be in a closed state. Then the slide bar 6 continues to move upward, driving the connecting plate 9 to move to the top of the groove of the striker 3 and then driving the striker 3 to move upward for a distance. During the upward movement, the striker 3 will generate pressure under the action of the closure of the body 1, and the glue inside the glue storage tank 2 will be sucked into the nozzle 4 through the connecting pipe 5. Then the slide bar 6 moves downward. When the slide bar 6 opens the baffle 12 under the action of the inclined plate 13, the slide bar 6 drives the connecting plate 9 to move downward to the bottom of the groove of the striker 3. Then the slide bar 6 drives the striker 3 to continue to move downward for a distance through the connecting plate 9, and the glue in the nozzle 4 is sprayed to the outside again. During the continuous reciprocating lifting and lowering process of the slide bar 6, the glue feeding and dispensing operations continue.
