[0002] A glue dispensing machine is an automated equipment widely used in industrial production. It can accurately control the amount and position of glue dispensing to achieve efficient and accurate glue dispensing operations. The working principle of a glue dispensing machine is usually to push the glue out through air pressure, screw or plunger, and apply glue in various shapes such as dots, lines and surfaces on the product according to a preset program. It is suitable for many industries, such as the packaging of circuit boards in electronics manufacturing, the bonding of parts in automobile manufacturing, and the fine gluing in handicraft production.

The motor, rotating shaft, and valve body of this dispensing valve are coaxially mounted on a bearing seat, with the countersunk hole on the rotating shaft corresponding to the position of the stepped through-hole on the valve body. One end of the screw is mounted within the stepped hole of the rotating shaft, and the other end is mounted within the stepped through-hole of the valve body. The spiral flow channel on the screw corresponds to the position of the mounting groove on the valve body. The valve body is also mounted with a fastening needle corresponding to the position of the screw. The barrel is also mounted on the bearing seat via a feed bracket, and the barrel discharge port is connected to the stepped through-hole of the valve body through a feed pipe and through the mounting groove on the valve body. This utility model is easy to install and disassemble, can provide accurate glue dosage, is suitable for dispensing medium and high viscosity fluids, and can also achieve reliable sealing. However, the size of the glue tip is single, and the glue tip needs to be frequently disassembled and replaced for different usage situations, which increases the workload and maintenance burden of the equipment.

By providing the pressure spring, the pressure spring facilitates the sliding of the auxiliary insertion rod during use, thereby increasing the usability of the device and reducing the difficulty of operating the device.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] The present invention provides a replacement device and a dredging device. When in use, the motor drives the gear to rotate, and the gear rotates while pushing the driving bar, which drives the rotating disk to rotate. The rotating disk drives the tube head to rotate and switch. When the appropriate tube head is switched, the tube head corresponds to the glue coating head up and down, and glue spraying can be carried out. After the glue spraying is completed, the auxiliary frame is rotated. At this time, the push handle is located under the tube head. The push handle is squeezed to drive the insertion rod to be inserted into the tube head to dredge the solidified glue and reduce blockage. The push handle is released, and the pressure spring loses its restraint and generates elastic force to squeeze the insertion rod to reset. At this time, the auxiliary frame is rotated away from the tube head. By setting the present invention, it is convenient to switch the tube head model according to actual needs, which reduces the situation of frequently replacing the tube head using tools, increases the switching speed of the equipment, improves the processing efficiency of the equipment, increases the ease of use of the equipment, reduces the difficulty of operating the equipment, and is convenient to use.
