The present invention relates to a discharge piece applied to a feeding device, in particular to a discharge piece with a quick-release mechanism, so that the user can quickly and conveniently disassemble the discharge piece and perform subsequent cleaning of the discharge piece piece of work.

Generally speaking, the staff are taking thick materials, such as food sauces (such as mustard sauce), ointments, lime plaster, pigment mud, etc., mostly by manual methods (such as digging, scraping, However, the manual method often causes the amount of thick material to be unstable for the staff each time. This move will not only affect the quality of the final product (such as: taste, efficacy), but also disadvantageous Manage the inventory of viscous materials by the industry.

In order to solve the aforementioned problems, the inventor intends to use machines to replace manual labor, and develops an automatic feeding device 1 , which is briefly described below, please refer to FIG. 1 , the automatic feeding device 1 includes a container 11 . and the base 12, wherein the container 11 is usually assembled to the top surface of the base 12 in a locking manner, and can be filled with thick materials, and the inner bottom surface of the container 11 is provided with a channel. 111, the thick material can flow out of the container 11 through the channel 111. In addition, the base body 12 is provided with a discharge member 121 , a driving device 122 (such as a motor) and a driving portion 123 , wherein the discharge member 121 is provided with a discharge flow channel 120 , and the discharge flow channel 120 communicates with the channel 111 , so that the thick material flowing out of the channel 111 can flow into the outlet channel 120 . In addition, one end of the discharge flow channel 120 is provided with a discharge nozzle 124, and the other end of the discharge flow channel 120 can be inserted into a rod body 125, so that the piston part 126 on the rod body 125 can be used for the discharge flow channel 120. The thick material is pushed to the discharge nozzle 124 so as to flow out through the discharge nozzle 124 .

On the other hand, please refer to FIG. 1 again, the end of the rod body 125 exposed from the discharge piece 121 will be connected with the driving part 123 , and the driving part 123 can be driven by the driving device 122 to drive The rod body 125 moves back and forth back and forth, so that the piston part 126 moves back and forth back and forth in the discharge channel 120 . In this way, when the worker activates the driving device 122 , the driving device 122 drives the driving part 123 in sequence. . When the rod body 125 moves back and forth, the piston portion 126 can push the thick material, so that the thick material flows out through the discharge nozzle 124. In other words, the staff only needs to control the operation amount of the driving device 122, that is, it can be adjusted The displacement distance of the piston part 126 can then achieve the effect of quantitatively extruding the thick material.

However, since the thick material needs to be stirred from time to time to avoid solidification and hardening, a stirring member 113 will be provided in the container 11, and the stirring member 113 will continue to rotate, so that the thick material can maintain a thick liquid state, but, If the thick material flowing into the discharge channel 120 cannot be pushed out of the discharge member 121 , it will be easy to solidify and harden after a period of time, thereby causing the discharge nozzle 124 to be blocked. Generally speaking, when the discharge nozzle 124 is blocked, the user only needs to take out the discharge member 121 and clean it, which is enough to solve the aforementioned blocking problem. However, in practice, please refer to FIG. 1 again. Usually, it is locked on the driving portion 123 , and the discharging member 121 is generally formed in one piece or in a locking manner. In this case, the disassembly is complicated. In particular, for non-professional maintenance users, the aforementioned disassembly process is not only troublesome, but also requires additional operating tools, which makes the user worry that the automatic feeding device 1 will be damaged due to errors in disassembly or assembly. When the automatic feeding device 1 cannot discharge the material, the maintenance personnel will be contacted for inspection and maintenance, which in turn leads to a lot of unnecessary maintenance costs and maintenance time.
