Description

Technical Field

[0001] The invention relates to the field of automatic hole opening for mushroom bags, and in particular to a small automatic hole opening machine for mushroom bags. Background Art

[0002] The existing patent (publication number: CN103609335B) proposes an automatic mushroom bag hole opening machine, including a frame, a round table is provided on the frame, a mushroom bag channel is provided on the round table, a puncture block is provided at the exit of the mushroom bag channel, the puncture block is provided with spikes, a support is installed on the bottom surface of the round table, and a spring is connected between the support and the round table. However, this device "when the mushroom bag passes through the mushroom bag channel, an extrusion effect is generated between the mushroom bag and the puncture block, and the support drives the spikes on the puncture block under the action of the spring to puncture and punch holes in the mushroom bag". During the punching process, each puncture block operates independently, and the force in each direction is uneven, which can easily affect the overall opening effect of the mushroom bag during the hole opening process. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the present invention provides a hole-opening wheel array group arranged in a ring, so as to ensure that holes are evenly opened around the mushroom bag in the process of the mushroom bag passing through the hole-opening wheel array group. Linkage groove wheels and linkage gears are respectively arranged on both sides of the hole-opening wheel, so that after the hole-opening wheels form a ring array, the hole-opening wheels will mesh with each other for transmission, without adding additional parts, simplifying the overall structure of the device, reducing production costs and daily maintenance costs. At the same time, one hole-opening wheel is provided with two groups of hole-opening needles. Compared with only a single group of hole-opening needles, the double groups of hole-opening needles can ensure the hole-opening density of the mushroom bag while providing fewer hole-opening wheels, thereby reducing the transmission level of the hole-opening wheel, making the movement of the hole-opening wheel smoother, and making the mushroom bag more evenly stressed during the hole-opening process, thereby achieving a small-scale automatic hole-opening machine for mushroom bags with better hole-opening effect.
