Bag feeding and removing mechanism for beverage extraction device

Abstract

The invention relates to a bag feeding and removing mechanism for a beverage extraction device. The mechanism comprises a machine base, a first part, a second part and two clamp plates, wherein a blocking portion is arranged at the front end of each clamp plate, and a groove is formed in front of each blocking portion. The mechanism is characterized in that blocking faces are arranged on the left side and right side of the first part, a guiding hole is formed in each clamp plate in the front-back direction, hook portions are arranged on the left side and right side of the second part, and the hook portions are located in the guiding holes and can slide front and back relative to the guiding holes; the front outer end face of each hook portion is in first contact fit with the front inner end face of the corresponding guiding hole, the rear hook face of each hook portion is in second contact fit with the rear inner end face of the corresponding guiding hole, a penetration hole allowing the corresponding hook portion to penetrate through is formed in each blocking portion, and the front inner end face of each hook portion is in third contact fit with the side face of the corresponding penetration hole. The mechanism is more reasonable in structural design, and bag removing and bag feeding are steadier and smoother.

Description

technical field [0001] The invention relates to a package-feeding and unpacking mechanism for a beverage extraction device with improved structure, wherein the beverage extraction device is mainly a coffee machine. Background technique [0002] Coffee machine is a kind of in beverage extracting device, and for making operation convenient, existing coffee machine has the function of realizing automatic unpacking. Such as the Chinese utility model patent "Automatic shedding mechanism of coffee bag in coffee machine" with the patent number ZL200720110811.2 (the announcement number is CN201044719Y), and the Chinese utility model patent "Beverage "Automatic Bag Dropping Mechanism of Preparation Device" both disclose a bag feeding and removing mechanism for a coffee machine. [0003] Both of the aforementioned two improved patents are equipped with two sets of guide grooves on the base to guide the front axle and the rear axle of the splint. There is no relative empty stroke bet...

AI Technical Summary

Problems solved by technology

[0005] 1. The left and right sides of the first component are used to guide and cooperate with the front outer surface of the groove. The guide surface has a first position and a second position, and the second position is located outside the first position and relatively forward. There is a smooth transition between the first position and the second position. The structure of the guide surface is complex and requires high machining accuracy, which is not conducive to manufacturing and increases manufacturing costs. Moreover, the opening and closing of the splint is realized through the cooperation of the guide surface and the hook, which is prone to jamming. In the dead case, the splint is not in place, so that the two parts cannot be completely closed during extraction.

[0006] 2. When packing, the splints on both sides are only limited by the side walls of the machine base to keep them moving inward. However, due to certain errors in assembly, the splints on both sides are loose, and the splints on both sides are loose. It will lead to the possibility that the blocking part at the front end of the splint will be stretched out, and then the blocking part at the front end of the splint will not be able to hold the beverage bag, resulting in unreliable packing, and the bag will be dropped during packing

[0007] 3. When extracting, the second contact and cooperation between the rear hook surface of the hook and the rear inner end surface of the guide hole forces the two splints to close together, and ensures that the annular edge of the beverage bag is located in the groove, so as to ensure the second The backward movement of the mechanism can make the grooves on the two splints move backward to drive the beverage bag out of the accommodating cavity. Because the second mechanism moves backward, the groove has a hole stroke in the guide hole. During this period of time, the friction Under the action of force, the backward movement of the second mechanism may drive the splint to move backward to a certain extent. At the same time, the second mechanism moves backward, and the front outer end surface of the hook part is separated from the front inner end surface of the guide hole. The splint may not be kept in the In-situ, that is, the ring edge of the drink pack may no longer be in the groove, which eventually leads to the inability to take out the drink pack smoothly and unstable unpacking
