Description

Technical Field

[0001] The utility model relates to the technical field of film-coating packaging equipment, in particular to a heat-shrinkable film-coating device for tea-making production. Background Art

[0002] Boiling tea is a traditional tea processing method, usually used to produce some special teas, such as black tea, Pu'er tea, etc. The following are the general steps of boiling tea:

[0003] Withering (spreading and drying): First, the freshly picked tea leaves must be withered, that is, the tea leaves are spread out and dried to allow the moisture of the tea leaves to evaporate slowly and soften the tea leaves. During this process, the color and aroma of the tea leaves will gradually change. Rolling: The tea leaves after withering must be rolled and twisted, the purpose is to destroy the cell structure of the tea leaves, promote the contact between the cell fluid in the tea leaves and the enzyme, and thus promote the subsequent fermentation process. The strength and time of rolling will affect the appearance and taste of the tea leaves. Fermentation (fermentation and corruption): The tea leaves after rolling must be fermented, generally under wet or dry pile conditions. In this process, the enzymes in the tea leaves will interact with the components in the tea leaves, produce complex chemical changes, and form the unique flavor and aroma of the tea leaves. Killing: After fermentation is completed, the tea leaves must be killed, that is, the tea leaves are treated with high temperature to stop the fermentation process. Killing can be done by steaming, baking, etc. Shaping: The tea leaves after killing must be shaped to make the appearance of the tea leaves neat and beautiful. Drying: The shaped tea leaves must be dried to reduce the moisture content of the tea leaves and improve the stability and shelf life of the tea leaves. The drying method can be sun drying, oven drying, etc.

[0004] After the tea leaves have gone through multiple production processes, they need to be weighed and packaged. To prevent the tea leaves from getting moldy due to excessive moisture during storage, the outside of the tea leaves can be coated. A coating device is required for the coating process. The existing coating device used in tea production requires manual weighing of the tea leaves, placing the tea leaves into the heat shrink film, and sealing the top of the heat shrink film, which makes the overall production process cumbersome and inefficient.

[0005] Existing, for this reason, we propose a heat shrinkable film coating device for tea production. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example

[0028] See also Figure 1-Figure 4The heat shrink film coating device for tea production shown in the figure includes a conveying platform 1, a conveying trough is provided on the surface of the conveying platform 1, and a conveyor belt 2 is installed in the conveying trough, a bracket 3 is arranged parallel to the surface of the conveying platform 1 and across the conveyor belt 2, a plurality of through rods 4 are passed through the top of the bracket 3, and the bottoms of the through rods 4 in the same extension line direction are screwed with spacers 5 arranged parallel to each other, the bottom of the spacers 5 is located above the conveyor belt 2, a tea frame 6 for centralized storage of processed tea leaves, and the bottom of the tea frame 6 is provided with a tea delivery port 7 located between adjacent spacers 5, a control closing component located below the tea delivery port 7 is installed at the bottom of the tea frame 6, linear slide rails 12 are installed on the surfaces of the two spacers 5 located on the edge side, and a film conveying component is installed between the tops of the guide rail sliders of the linear slide rails 12.

[0029] Under the action of the partition 5, the space above the conveyor belt 2 is divided into equal intervals to form multiple conveying channels, so that the tea bags after the film coating process can be independently conveyed. In addition, the number of tea delivery ports 7 is the same as the number of intervals formed by the partition 5.

[0030] Furthermore, the control closing component includes a bottom film 17 symmetrically arranged at the bottom of the tea frame 6 and located on both sides of the corresponding tea delivery port 7, and the adjacent sides of the bottom film 17 are constructed with notches for limiting the rotation of the end of the telescopic rod 18, the other end of the telescopic rod 18 is rotatably connected to the baffle frame 19, and the top edge side of the baffle frame 19 is rotatably connected to the bottom surface of the tea frame 6.

[0031] When the telescopic rod 18 is extended, the top of the baffle frame 19 rotates around its edge side, and the bottoms of the baffle frames 19 approach each other. After the baffle frames 19 are fitted together, the bottom of the tea delivery opening 7 is closed to stop the delivery of tea. When the telescopic rod 18 is retracted, the top of the baffle frame 19 rotates around its edge side, and the bottoms of the baffle frames 19 are separated from each other, so that the tea leaves in the tea frame 6 fall into the heat shrink film delivered by the film conveying component below through the tea delivery opening 7 and the gap at the bottom of the baffle frame 19.

[0032] Furthermore, the film conveying assembly includes a film bonding frame 14 located above the middle position of the partition, and connecting blocks 13 are fixed on both sides of the film bonding frame 14. The connecting blocks 13 on the side walls of the film bonding frame 14 at both ends are bonded to the surface of the guide rail slider of the linear slide rail 12. A horizontal push rod 15 parallel to the axial direction of the partition 5 is fixed on the surface of the film bonding frame 14, and a hot melt sheet 16 is installed at the end of the horizontal push rod 15.

[0033] The inner wall of the film laminating frame 14 is bonded with a silicone strip. When the heat shrinkable film is unfolded and attached to the inner wall of the film laminating frame 14, the silicone strip can keep the heat shrinkable film and the film laminating frame 14 in close contact.

[0034] Furthermore, a vertical reinforcement rod 11 is connected between the bottom of the tea frame 6 and the surface of the conveying platform 1 to support the tea frame 6, a transverse reinforcement rod 10 is connected and bonded between the side wall of the tea frame 6 and the side wall of the bracket 3, a bonding strip 8 is fixed to the bottom surface of the side where the tea frame 6 and the bracket 3 are bonded, and a number of equidistantly distributed plug blocks 9 are inserted between the side wall of the bonding strip 8 and the side wall of the bracket 3.

[0036] It should be noted that the utility model is a heat shrink film coating device for tea production. When in use, the tea leaves processed through multiple processes are poured into the tea frame 6, and the linear slide rail 12 controls the horizontal movement of the laminating block to move the heat shrink film pre-laminated on the inner wall of the film laminating frame 14 to the corresponding tea delivery port 7. Then the telescopic rod 18 is retracted, and the top of the baffle frame 19 rotates around its edge side, and the bottom of the baffle frame 19 is separated from each other, so that the tea leaves in the tea frame 6 fall into the heat shrink film delivered by the film conveying component below through the tea delivery port 7 and the gap at the bottom of the baffle frame 19, and the telescopic rod 18 is controlled according to the designed delivery time. The shrink rod 18 is reset and extended, so that the bottom of the baffle frame 19 fits and closes the tea inlet 7. When the tea falls, it falls accurately into the heat shrink film below. At this time, the conveyor belt 2 is in a stopped state. The heat shrink film is filled with tea and falls on the surface of the conveyor belt 2 as a whole. Then the horizontal push rod 15 drives the hot melt sheet 16 to move horizontally. The hot melt sheets 16 fit together to seal the heat shrink film. After sealing, the conveyor belt 2 is started, and the tea bag after the film coating is controlled to move to the end of the conveyor platform 1, and the linear slide rail 12 is controlled to move the film bonding frame 14 to the end opposite to the moving direction of the tea bag, and a new heat shrink film is attached to the film bonding frame 14.
