The double-head rubber inlet and outlet plunger pump according to an embodiment of the utility model is described below with reference to FIGS. 1 to 3 .

As shown in Figures 1 to 3, the double-headed inlet and outlet glue plunger pump is mainly used in glue dispensing equipment, aiming to reduce the number of parts of the glue dispensing equipment, thereby reducing manufacturing costs, and improving the production efficiency of the glue dispensing equipment. Specifically, the double-headed inlet and outlet glue plunger pump of the utility model includes two glue dispensing valves 100, a reciprocating push-pull member 200 and a reciprocating drive mechanism 300. The two glue dispensing valves 100 have the same structure, and the pistons 110 of the two glue dispensing valves 100 are arranged opposite to each other. The glue inlet of the glue dispensing valve 100 is connected to the colloid storage tank of the glue dispensing assembly, and the glue outlet is connected to the glue dispensing head. The two ends of the reciprocating push-pull member 200 are respectively connected to the pistons 110 of the two glue dispensing valves 100, and the reciprocating push-pull member 200 is used to drive the two pistons 110 to work alternately. Specifically, when the reciprocating push-pull member 200 moves toward one of the dispensing valves 100, the piston 110 of the dispensing valve 100 that the reciprocating push-pull member 200 is close to is in a compressed state, while the piston 110 of the dispensing valve 100 that the reciprocating push-pull member 200 is away from is in a stretched state. At this time, the dispensing head of the dispensing valve 100 in the compressed state discharges glue, and the dispensing head of the dispensing valve 100 in the stretched state extracts glue.

The reciprocating drive mechanism 300 is connected to the reciprocating push-pull member 200 for driving the reciprocating push-pull member 200 to move back and forth, thereby realizing the alternating operation of the two dispensing valves 100. By driving the two dispensing valves 100 to work at the same time through a single drive mechanism, a large amount of manufacturing cost is saved compared to the existing dispensing structure, the number of structural parts of the dispensing equipment is reduced, and later maintenance is easier. In addition, the manufacturing cost of the equipment is significantly reduced, which is conducive to the construction of the production line and improves production efficiency.

In some embodiments of the present invention, as shown in FIG. 1 and FIG. 3 , the dispensing valve 100 includes a driving cavity 120, a piston 110 slides in the driving cavity 120, and an end of a reciprocating push-pull member 200 is connected to the piston 110. Specifically, the driving cavities 120 of the two dispensing valves 100 are on the same straight line and close to each other, so that the reciprocating push-pull member 200 can drive the two dispensing valves 100 alternately. Improving the response rate of the dispensing valve 100 facilitates improving the production rhythm of the production line.

In some embodiments of the present invention, as shown in Figures 1 and 3, a guide sleeve 130 is provided at the end of the driving cavity 120, and the reciprocating push-pull member 200 passes through the guide sleeve 130 to be connected to the piston 110, and the diameter of the reciprocating push-pull member 200 is equal to the inner diameter of the guide sleeve 130.

Specifically, the inner diameter of the guide sleeve 130 is equal to the outer diameter of the reciprocating push-pull member 200 , and the reciprocating push-pull member 200 is cylindrical. The guide sleeve 130 can guide the reciprocating push-pull member 200 to move into the driving cavity 120 , thereby improving the smoothness of the movement of the piston 110 .

In some embodiments of the utility model, as shown in FIG2 and FIG3, a rack structure 210 is provided on the side wall of the reciprocating push-pull member 200, and the rack structure 210 is meshed and connected with the reciprocating drive mechanism 300. Specifically, the rack structure 210 of the reciprocating push-pull member 200 is located in the middle area of the rod body, and the distance from the middle of the reciprocating push-pull member 200 to the two dispensing valves 100 is equal. The stroke of the rack structure 210 is evenly divided into two parts, and the pistons 110 of the two dispensing valves 100 each occupy one part of the rack stroke, ensuring that the working rhythm of the two dispensing valves 100 remains consistent.

In some embodiments of the present utility model, as shown in FIG. 1 and FIG. 2 , the reciprocating drive mechanism 300 includes a driving part 310 and a transmission part 330, wherein the transmission part 330 is disposed in a transmission seat 320, the transmission seat 320 is connected to the driving part 310, the output shaft of the driving part 310 is transmission-connected to the transmission part 330, and the transmission part 330 is meshed with the rack structure 210. Specifically, the transmission part 330 is disposed in the transmission seat 320, which can effectively prevent the transmission part 330 from being damaged, thereby protecting the transmission part 330.

In some embodiments of the present invention, as shown in Figures 1 to 3, two dispensing valves 100 are respectively fixedly connected to the two sides of the transmission seat 320. Specifically, the housings of the dispensing valves 100 are respectively fixed to the two sides of the transmission seat 320, so that the connection positions of the reciprocating push-pull member 200 and the dispensing valves 100 are relatively fixed to prevent the reciprocating push-pull member 200 from slipping.

In some embodiments of the present invention, as shown in FIG2 and FIG3, the transmission part 330 includes a transmission tooth 331, the transmission tooth 331 is keyed to the output shaft of the driving part 310, and the transmission tooth 331 is meshed with the rack structure 210. Specifically, the transmission tooth 331 is meshed with the rack structure 210 for transmission, and the driving part 310 uses a servo motor, which can more accurately control the rotation of the transmission tooth 331. The servo motor has higher precision and faster response speed, and can improve the production efficiency of the production line.

In some embodiments of the present invention, as shown in FIG. 2 and FIG. 3 , the transmission part 330 includes a limit ring 333, a limit groove 333-1 is provided on the periphery of the limit ring 333, and a limit column (not shown in the drawings) is provided on the transmission tooth 331, and the limit column penetrates into the limit groove 333-1. When the transmission tooth 331 rotates, the limit column slides in the limit groove 333-1. Specifically, when the limit column touches the end of the limit groove 333-1, the servo motor reverses to drive the transmission tooth 331 to reverse, so that the two dispensing valves 100 work alternately.

In a further embodiment, as shown in FIG2 , the limit ring 333 abuts against the spoke plate of the transmission tooth 331 to limit the axial displacement of the transmission tooth 331. Specifically, when the two dispensing valves 100 need to be maintained, the dispensing tooth 331 can be disassembled, and the driving part 310 and the reciprocating push-pull member 200 are separated, so that the staff can clean each component separately.
