Therefore, the above terms should not be understood as limiting the present invention.

[0017] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0018] refer to Figures 1 to 3 The embodiment of the present application provides a glue injection pump, comprising a housing 10 and a piston shaft 20, wherein the housing 10 comprises a discharge block 11, an upper pump body 12 and a lower pump body 13 connected in sequence along the axial direction, wherein the upper pump body 12 and the lower pump body 13 cooperate to form a shell cavity 101 of the housing, and the discharge block 11 is provided with a discharge port 102 connected to the shell cavity 101, and the shell cavity 101 is divided into a discharge storage area 1011, a feed storage area 1012 and a feed port 1013 in sequence, wherein the discharge port 102 is connected to the discharge area 103 through the discharge area 103. The discharge storage area 1011 is connected, wherein the piston shaft 20 is arranged in the shell cavity 101 in a manner that it can reciprocate along the axial direction, and the piston shaft 20 is provided with a sealing portion 21 near the middle, wherein the sealing portion 21 is configured to: when the piston shaft 20 moves in a direction close to the discharge block 11, it can block the connection between the discharge storage area 1011 and the discharge area 103, and at the same time, it can also make the feed port 1013, the feed storage area 1012 and the discharge storage area 1011 synchronously connected, and in addition, the The sealing portion 21 is also configured such that when the piston shaft 20 moves in a direction away from the discharge block 11, the connection between the feed port 1013 and the feed storage area 1012 can be blocked, and at the same time, the discharge storage area 1011, the discharge area 103 and the discharge port 102 can be synchronously connected. In this way, during the upward movement of the piston shaft 20, the connection between the discharge storage area 1011 and the discharge area 103 is blocked, while the feed port 1013, the feed storage area 1012 and the discharge storage area 1011 are connected to each other, so that the rubber in the barrel can be extracted from the feed port 1013 and the discharge storage area 1012. The rubber material stored in the discharge storage area 1011 is connected to the discharge storage area 103 and the discharge port 102. The rubber material stored in the discharge storage area 1011 flows into the discharge port 102 through the discharge area 103, and is then drawn from the discharge port 102 to the place where it is needed. Such a cyclic reciprocating movement can realize the continuous transportation of the rubber material, and the rubber material is not easy to adhere to the internal components, and is easy to clean and maintain.

[0019] In one embodiment, the piston shaft 20 includes an upper piston shaft 22, a piston connector 23 and a lower piston shaft 24 which are connected in sequence along the axial direction, wherein the upper piston shaft 22 is close to the upper pump body 12, and the sealing portion 21 is arranged on the piston connector 23, so that the installation of the piston shaft 20 can be facilitated, and the processing, manufacturing and subsequent maintenance of the sealing portion 21 can be facilitated. In some cases, the new piston connector 23 can be directly replaced for replacement use.

[0020] In one embodiment, the housing 10 is provided with a clamping block 14 at the top of the discharge block 11 (i.e., the side away from the upper pump body 12). The clamping block 14 is provided with a moving channel 104 for directional movement of the upper piston shaft 22, and a seal that seals with the upper piston shaft 22 is provided in the moving channel 104, so that the discharge block 11 can be firmly fastened to the upper pump body 12 through the clamping block 14, making the overall structure of the injection pump more stable.

[0021] In one embodiment, a main softener inlet channel 105 is opened on the side of the pressing block 14, so that the softener can be injected into the fitting point between the seal and the upper piston shaft 22, so that the flexibility and stability of the reciprocating movement of the piston shaft 20 can be ensured by the softener.

[0022] Taking into account that most of the rubber materials in industrial applications are highly viscous, which can reach 20,000 pas, a part of the rubber materials can be transported at normal temperature, while another part of the rubber materials needs to maintain a certain temperature to support flow, otherwise it is easy to solidify and difficult to extract. Therefore, as a preferred embodiment, the discharge block 11 is provided with a heating port 106 near the discharge port 102, wherein the heating port 106 is mainly for the transportation of heated rubber materials, and can be connected to a heating pack, and can also be used to place an electric heating element, so as to control the temperature of the discharge port 102 through the heating port 106 to avoid the solidification of the rubber materials during the feeding process.
