Description

Technical Field

[0001] This utility model relates to the field of cylinder technology, specifically to a cylinder pump assembly. Background Technology

[0002] A cylinder is a pneumatic actuator that converts the pressure energy of compressed gas into mechanical energy in pneumatic transmission; there are two types of cylinders: those that perform reciprocating linear motion and those that perform reciprocating oscillating motion.

[0003] A search revealed that patent application number 201821385589.1 discloses a cylinder, a pump body assembly, and a device with the pump body assembly. The cylinder includes: a cylinder body with a working chamber and an air inlet communicating with the working chamber; a first flow guiding structure disposed on the cylinder body and communicating with the air inlet and the working chamber respectively; and at least one second flow guiding structure disposed on the cylinder body, communicating with the first flow guiding structure and extending from the first flow guiding structure toward the working chamber. By setting the first flow guiding structure and the second flow guiding structure extending from the first flow guiding structure toward the working chamber, the airflow vortex generated at the connection between the air inlet and the working chamber can be guided to the first flow guiding structure and further guided to the second flow guiding structure, thereby making full use of the airflow that originally formed the airflow vortex and reducing energy loss. At the same time, when the substance entering the air inlet is a refrigerant or contains a refrigerant, the cylinder can be cooled and dissipated more fully by guiding the refrigerant to the first and second flow guiding structures.

[0004] The aforementioned application documents effectively cooled the equipment and ensured its stable operation by incorporating heat dissipation components. However, existing glue pumps present a series of problems that urgently need to be addressed in actual use. The pump cylinder radius is generally too small, resulting in insufficient glue spraying pressure. To meet operational requirements, the pump cylinder must be started frequently. Frequent starts exacerbate wear and tear on components, significantly shortening the lifespan of the glue pump, increasing equipment maintenance costs, and negatively impacting production efficiency.

[0005] Therefore, we propose a cylinder pump assembly. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a cylinder pump assembly, which solves the problems of insufficient power due to the small pump body and piston diameter of existing devices, requiring high-frequency reciprocating drive and resulting in a short service life.

[0010] The specifications of the piston assembly are the same as those of the magnetic ring plate. By increasing its diameter, the power can be increased simultaneously, and the pressing capacity and flow rate of the glue pump can be increased, which greatly solves the problem of insufficient glue supply in production. With the increased capacity, the cylinder does not need to be frequently reversed, thus increasing the service life of the glue pump.

[0011] As a preferred embodiment of this utility model, a flat washer is provided on the top of the lower magnetic ring pressure plate, and a nut is fitted on the flat washer.

[0013] As a preferred embodiment of this utility model, a piston disc is provided on the bottom side of the upper magnetic ring pressure plate, a piston sealing ring is assembled at the bottom of the piston disc, and an O-ring is assembled between the upper magnetic ring pressure plate and the piston disc.

[0014] The components on the bottom side of the upper magnetic ring pressure plate enhance the sealing effect and further ensure the practicality of the cylinder.

[0015] As a preferred embodiment of the present invention, the pump shaft assembly consists of a pump body, a pump shaft, and a pump cover from top to bottom, and the pump shaft assembly is fitted inside the piston assembly.

[0016] The pump shaft assembly ensures the overall driving effect of the device.

[0017] As a preferred embodiment of this utility model, a pressure regulating valve assembly is fixedly installed on the top of the upper cover assembly via a mounting plate, a controller assembly is assembled on the outer side of the cylinder body, and a solenoid valve assembly is also fixedly installed on the outer wall of the cylinder body via a mounting plate.

[0018] This utility model provides a cylinder pump assembly. It has the following beneficial effects:

[0019] This cylinder-pump assembly increases power and pressure capacity by increasing the cylinder diameter and the diameter of the inner piston assembly, simultaneously increasing the glue pump capacity and greatly solving the problem of insufficient glue supply. In addition, with the increased capacity, the cylinder does not need to be frequently reversed, increasing the service life of the glue pump. Furthermore, the device uses a pressurized air source as the input end to ensure driving force, solving the problem of insufficient power due to the small pump body and piston diameter of existing devices, which require high-frequency reciprocating drive and have a short service life.

The outer side of the cylinder body 1 is equipped with a controller assembly 8, and a solenoid valve assembly 5 is also fixedly mounted on the outer wall of the cylinder body 1 via a mounting plate.

[0033] In addition, the surface of each component in this technology is treated with a special coating, which increases the surface strength of the parts, enhances the wear resistance of the parts, and improves the high temperature resistance and corrosion resistance of the product.
