Description

Technical Field

[0001] The present invention relates to the technical field of tea packaging equipment, and more particularly to a wrapping paper machine for Pu-erh tea cakes. Background Art

[0002] Pu-erh tea grows in areas such as Xishuangbanna, Lincang, and Pu'er in Yunnan Province. It is a large arbor, up to 16 meters tall. The young branches have fine hairs, and the terminal buds have white pubescence. The leaves are thinly leathery and elliptical. The flowers are axillary and are covered with pubescence. There are 2 bracts, which fall off early. The sepals are 5, nearly circular, and hairless on the outside. The petals are 6-7, obovate, and hairless. The stamens are 8-10 mm long, free, and hairless. The ovary is 3-locular and covered with fuzz; the style is 8 mm long and 3-lobed at the apex. The capsule is oblate triangular spherical. There is 1 seed in each locule, nearly circular, with a diameter of 1 cm. Pu-erh tea pays attention to brewing techniques and tasting arts, and can be drunk pure or mixed. The tea soup of Pu-erh tea is orange-yellow and thick, with a high and sharp persistent aroma, a unique fragrance type, a strong and mellow taste, and is durable for brewing. Pu-erh tea cakes are all compressed into cake shapes from Pu-erh tea, commonly known as Pu-erh tea cakes. Pu-erh tea is mostly stored and transported in the form of cake pressing. Historically, one cake was 357 grams, and seven cakes were a load. This is convenient for calculation and transportation by mules and horses.

[0003] When selling, Pu-erh tea cakes generally need to be packaged. Most of the existing Pu-erh tea cake packaging is manual packaging, with a low level of automation, low packaging efficiency, large labor intensity of workers, and it is not easy to control the packaging quality.

[0124] The fourth cylinder 1415 works to drive the supporting plate 1421 to catch the material to prevent the material from being damaged due to the distance between the material and the conveyor belt O; the movable side plate 1406 can be swung and fixed within a certain range to facilitate the connection between the finished product discharge and the external conveyor belt.

[0125] The working process is as follows: The sucker in the tea cake feeding mechanism adsorbs the tea cake from the external conveyor belt onto the sorting tray in the feeding turntable assembly through vacuum adsorption, and the tea cake is rotated to the die - closing station by the servo indexing plate. Meanwhile, the tissue paper is separated and fed into the paper - feeding conveyor belt assembly through the peripheral page - separating mechanism. The blower is started, and the tissue paper is adsorbed on the upper - opening conveyor belt. After the fiber optic sensor determines that the tissue paper is in place, the mini - clamp clamps the tissue paper to the die - closing station. Then, the ejector cylinder jacks the tea cake upward from the station to below the tissue paper, and the upper cylinder works simultaneously to clamp the tea cake and the tissue paper together. After that, the mini - clamp opens and returns to the standby position waiting for the next action. At the same time, the die - closing assembly, the ejector cylinder, and the upper cylinder work simultaneously to close the mold, press out the embossing on the tissue paper, and then the upper cylinder and the ejector cylinder synchronously send the tea cake and the tissue paper to the standby closing tray on the closing turntable. Meanwhile, the feeding pick - up piece at the standby position opens during die - closing, and after the tea cake and the tissue paper enter the closing tray, the feeding pick - up piece resets. The closing tray clamps the tea cake and the tissue paper under the self - pulling force of the clamping block and the tension spring. Subsequently, the closing turntable rotates one station. During the rotation, the cam follower on the closing piece turntable collides with the one on the full - closing fixed seat to perform cam - track movement, changing the closing tray from the fully - open state to the fully - tightened state within one station rotation. When the closing tray reaches the next station, the dialing arm drives by the cylinder to dial the closing tray to the semi - open state. The closing turntable rotates one more station, and the paper - sorting assembly re - sorts the wrapping tissue paper for the second time. The closing tray continues to rotate to the next station, where the label - moving mechanism and the inverted label - sticking machine perform labeling. The label - pressing sucker head presses the label on the label - removing moving plate, and the cylinder drives the moving plate to move backward to complete label removal. Then, the adjustable - stroke cylinder pastes the label on the tea cake at this station. After labeling is completed, the closing tray continues to rotate to the next station. During the rotation, the follower cam collides with the closing piece turntable, and due to the rotation relationship of the turntable itself, the closing tray is fully opened. After reaching the next station, the lifting plate rises, the fully - open pick - up piece opens the clamping block of the closing tray. After the packaged tea cake sinks due to its own gravity, it is caught by the lifting plate. The clamping block of the closing tray then resets under the spring tension, the lifting plate returns to the standby position, the packaged tea cake is conveyed out by the round belt, the closing tray enters the next standby station, and then enters the die - closing station from the standby station.
