Description

Technical Field

[0002] Traditional Chinese medicine tea bags are a more convenient, portable, and brewable alternative to traditional decoction methods. Based on their efficacy, they can be categorized as health and wellness, conditioning, and disease prevention. A traditional Chinese medicine tea bag typically consists of a herbal bag, a marking string, and a paper label. The marking string connects the bag and the label, and the paper label can be hung on the cup for positioning during brewing.

[0003] At present, most tea bag packaging machines adopt a vertical structure, but most of them operate in an open environment, such as a tea bag packaging machine disclosed in the existing patent CN201910842177.9, and a tea bag encapsulation machine disclosed in the existing patent CN202021552538.0. This type of tea bag packaging machine can meet the requirements for general tea bags, but for Chinese medicine tea bags, the hygiene requirements are higher, and the open packaging environment is not conducive to ensuring its hygiene, especially the inner packaging cloth and outer packaging paper are always in the open environment of the workshop, and the inner packaging is mostly breathable. In addition, due to the design of the inner and outer packaging stations, there is a certain distance between the inner and outer packaging stations of most packaging machines, which increases the probability of the inner bag being contaminated with dust on the one hand, and lengthens the length of the working line and increases the volume of the equipment on the other hand.

DETAILED DESCRIPTION

[0032] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other unless they conflict. For the convenience of description, the words "upper", "lower", "left", and "right" appearing below only indicate the upper, lower, left, and right directions consistent with the drawings themselves and do not limit the structure.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Examples, such as Figures 1-11As shown, the present invention provides a packaging device for preparing Chinese medicine composition tea bags, comprising an inner packaging mechanism 2, an outer packaging mechanism 3, a wire feeding mechanism 4, a label feeding mechanism 5, and a control box 6. A coil support mechanism 7 is provided at the supply end of each of the inner packaging mechanism 2 and the outer packaging mechanism 3. A tea hopper 1 is also provided above the inner packaging mechanism 2. The Chinese medicine tea in the tea bags can be conveyed via a chain bucket conveyor mechanism or can be weighed and discharged from a material tank with a valve. On this basis, the inner packaging mechanism 2, outer packaging mechanism 3, wire feeding mechanism 4, label feeding mechanism 5 and coil support mechanism 7 provided by the present invention are all arranged in a chassis 8, and the chassis 8 is C-shaped and includes an upper cavity 81, an intermediate cavity 82 and a lower cavity 83 connected in sequence. The upper cavity 81 and the lower cavity 83 are both provided with a flip cover 85 for replacing materials. A transparent door 84 is provided on the front side of the chassis 8. The tea hopper 1 is arranged on the top of the chassis 8 and is connected to the inner packaging mechanism 2. The wire feeding mechanism 4 and the label feeding mechanism 5 are arranged side by side on the left and right. It is arranged in the upper cavity 81, the inner packaging mechanism 2 and the outer packaging mechanism 3 are arranged side by side in the middle cavity 82, and a chute 9 connected to the inner packaging mechanism 2 and the outer packaging mechanism 3 is provided between the inner packaging mechanism 2 and the outer packaging mechanism 3. The two sets of the coil support mechanisms 7 are arranged side by side in the lower cavity 83, and a discharge hopper 10 is provided inside the chassis 8 and is located in the discharge direction of the outer packaging mechanism 3. The end of the discharge hopper 10 is located outside the chassis 8, and a cutting mechanism 11 is provided between the inner packaging mechanism 2 and the chute 9, and between the outer packaging mechanism 3 and the discharge hopper 10.

[0035] Specifically, considering that the weight and volume of the inner and outer wrapping rolls are greater than the weight of the wire and label paper, the installation space for the inner and outer wrapping rolls is set in the lower chamber 83. The space in the lower chamber 83 is larger than the space in the upper chamber 81. This simplifies the difficulty of replacing the paper rolls. When changing materials, the corresponding flap 85 can be opened to replace them, which helps improve work efficiency. To pull the ends of the inner and outer wrapping rolls onto the corresponding inner and outer wrapping mechanisms 2 and 3, the staff can simply open the box door 84 to operate. The present invention adopts a chassis 8 as an isolation structure between the equipment and the workshop environment, and comprehensively arranges the inner packaging mechanism 2, the outer packaging mechanism 3, the wire feeding mechanism 4, the label feeding mechanism 5 and the control box 6, so that the main operation processes of the inner packaging and outer packaging are carried out in a relatively closed environment, which is beneficial to improving the hygiene of the Chinese medicine composition tea bags and shortening the assembly line length of the inner packaging station and the outer packaging station. The inner packaging product delivered to the inner packaging station is cut by the upper cutting mechanism 11 and can enter the outer packaging station along the chute 9. After the outer packaging station performs the final packaging on the inner packaging product, it is cut by the lower cutting mechanism 11 and can be output from the chassis 8 along the discharge hopper 10, thereby realizing efficient connection between the inner packaging station and the outer packaging station, which is beneficial to improving the space utilization rate of the equipment.

[0036] like Figure 3 、 Figure 5 and Figure 6 As shown, the outer packaging mechanism 3 provided by the present invention includes an outer packaging guide plate 31, at least two friction transmission rollers 16 are arranged on the outside of the outer packaging guide plate 31, and the end of the friction transmission roller 16 is provided with a reduction motor 17 located on the outside of the chassis 8. The cross-section of the outer packaging guide plate 31 is C-shaped and its inner surface is used to connect with the chute 9. The guide track of the outer packaging guide plate 31 is n-shaped and its diameter gradually narrows from bottom to top and then gradually narrows from top to bottom. The outer packaging guide plate 31 is used to guide the outer packaging paper to move along its outer surface, and a first side seam sealing machine 32 and a first port sealing machine 33 are provided on the side of the outer packaging guide plate 31 and in the direction extending toward the discharge hopper 10. In this way, the free end of the outer packaging paper roll is pulled out and guided to the outer surface of the outer packaging guide plate 31. The continuous operation of the friction conveying roller can form a continuous conveying path for the outer packaging paper. The outer packaging paper gradually shrinks from a longer width to a width close to forming a closed side seam. The side seam is heat-sealed by the first side seam sealing machine 32, and the upper and lower ports of the product are heat-sealed by the first port sealing machine 33, and finally cut by the cutting mechanism 11.

[0037] In order to improve the efficiency of paper labeling, presentation and inner packaging, such as Figure 3 、 Figure 7 and Figure 8 As shown, the label feeding mechanism 5 provided by the present invention includes a paper roller 51 connected perpendicularly to the rear wall of the chassis 8. A cutting roller 52 is disposed within the upper cavity 81. A paper outlet 53 extending from the end of the upper cavity 81 to the outer packaging mechanism 3 is provided in the paper feeding direction of the cutting roller 52. The paper outlet 53 is connected to the outer packaging mechanism 3 through a paper outlet 53. A material feeding mechanism 12 is hingedly connected to the back of the paper outlet 53. The paper roller 51 is used to load a roll of label paper. The free end of the roll is pulled out to the cutting roller 52. A cutter is disposed on the roller surface of the cutting roller 52. The cutter cuts a single label after a single rotation. The cut label is then fed by the cutting roller 52 into the paper outlet 53 and slides down the paper outlet 53.

[0038] like Figure 5 and Figure 8 As shown, the interior of the intermediate cavity 82 is equipped with a first contact mechanism 13 that moves in a telescopic manner toward the paper outlet slot 53. This first contact mechanism 13 is used to crimp one end of the paper label and the wire rod. A second contact mechanism 14 is provided on the side of the material chute 9 to crimp the other end of the wire rod to the inner packaging of the tea bag. The first contact mechanism 13 is driven by an air cylinder. Its end features a dispensing head with an area significantly larger than the end of the marking line. The dispensing head is connected to the glue source via a hose. Driven by the air cylinder, the dispensing head can quickly contact the marking line. The dispensing point can be the end of the marking line or the very front end of the marking line, thereby ensuring the quality and efficiency of the first contact.

[0039] Furthermore, the interior of the paper outlet slot 53 is provided with two plate holes 54 spaced apart in the upper and lower directions, and an anvil board 55 connected to the paper outlet slot 53 is provided in the direction opposite to the plate hole 54, and the anvil board 55 has a certain flipping margin or vertical displacement margin between it and the slot surface of the paper outlet slot, so that it and the baffle 122 have a secondary action effect, and the wire feeding mechanism 4 passes the end of the wire through the plate hole 54 and the anvil board 55, and the material digging mechanism 12 includes a material digging plate 121, and baffles 122 that alternate with the plate holes 54 are provided at both ends of the material digging plate 121, and the end face of the baffle 122 is provided with a cutting edge, and the cutting edge is used for cutting wire, and a material digging cylinder 123 is provided below the material digging plate 121. On the path of the paper label sliding down, the telescopic end of the material-diverting cylinder 123 descends, and the lower end of the material-diverting plate 121 turns upward and is inserted into the lower plate hole 54, intercepting the previous paper label. At the same time, the free end of the wire hangs down from the gap between the plate hole 54 and the anvil 55 to the paper label, and the first point connection mechanism 13 presses the paper label and one free end of the wire; the telescopic end of the material-diverting cylinder 123 is lifted up, and the upper end baffle 122 of the material-diverting plate 121 is inserted into the upper plate hole 54. 4, on the one hand, it blocks the next paper label that is about to slide down, and on the other hand, its cutting edge hits the anvil 55 to cut the marking line. The previous paper label is still kept on the lower baffle 122, and the other end of the marking line hangs down into the chute 9. The second point connection structure presses the marking line on the inner package; the material cylinder 123 continues to extend, and the marking line can be transferred to the outer packaging station along with the inner package; after the material cylinder 123 reaches its upper dead center, it starts to enter the next action cycle.

[0040] In order to ensure that the wallpaper mark at the end of the marking line is dropped into the chute 9 in advance, Figure 3 、 Figure 7 and Figure 8 As shown, the material joining direction of the label feeding mechanism 5 and the wire feeding mechanism 4 provided by the present invention is provided with a blowing mechanism 15, which includes a blowing pipe 151 located in the middle cavity 82. The blowing pipe 151 is used to blow one end of the wire material toward the inner wall of one side of the chute 9. The supply end of the blowing pipe 151 is provided with a pulse tank 152, and the pulse tank 152 is arranged on the outside of the chassis 8. In this way, after the material feeding mechanism 12 cuts the marking line, the blowing pipe 151 provides assistance to the marking line to move downward, and enables it to stick to one wall of the chute 9, which is conducive to improving the second point connection mechanism 14 to press the end of the marking line onto the inner package of the product. The second point connection mechanism 14 can adopt a rapid hot pressing method, and the cylinder drive hot pressing end completes the telescopic action on the side of the chute 9. Its hot pressing working surface is much larger than the cross-section of the end of the marking line, which is conducive to improving its efficiency in simultaneous thermal contact with the marking line and the inner package of the product, thereby improving the quality of the second point connection.

[0041] like Figure 7 and Figure 8As shown, in order to control the length of the marking line, the wire feeding mechanism 4 provided by the present invention includes a wire roller 41 vertically connected to the rear wall of the chassis 8, a stepping traction roller 42 is provided on one side of the wire roller 41, and a traction cylinder 43 located on the outside of the chassis 8 is provided at the end of the stepping traction roller 42. The traction cylinder 43 is used to drive the stepping traction roller 42 to reciprocate up and down, and the stepping traction roller 42 is provided with a threading hole 44. Among them, the traction cylinder 43 performs a vertical telescopic movement on the outside of the chassis 8, thereby driving the stepping traction roller 42 to rise and fall, and the stepping traction roller 42 uses the pressure of its threading hole 44 on the wire to pull out a length from the winding part, and hang down from between the plate hole 54 and the anvil 55, so that it has a controllable length and drooping direction, thereby ensuring that the wire markings subsequently cut are within a certain standard range.

[0042] like Figure 3 、 Figure 5 and Figure 6 As shown, in order to improve the efficiency of the front and rear movement connection of the inner packaging mechanism 2, the inner packaging mechanism 2 provided by the present invention includes an inner packaging guide plate 21, and the outer side of the inner packaging guide plate 21 is provided with a friction transmission roller 16, and the end of the friction transmission roller 16 is provided with a reduction motor 17 located on the outside of the chassis 8. The cross-section of the inner packaging guide plate 21 is C-shaped and its inner surface is used to connect with the tea hopper 1. The guide track of the inner packaging guide plate 21 is n-shaped and the vertical path length is greater than that of the outer packaging guide plate 31. The inner packaging guide plate 21 is used to guide the inner packaging cloth to move along its outer surface, and the side and bottom of the inner packaging guide plate 21 are respectively provided with a second side seam sealing machine 22 and a second port sealing machine 23. In this way, the free end of the inner packaging cloth roll is pulled out and guided to the outer surface of the inner packaging guide plate 21. The continuous operation of the friction conveyor roller can form a continuous conveying path for the inner packaging cloth roll. The inner packaging cloth roll gradually shrinks from a longer width to a width close to forming a closed side seam. The side seam is heat-sealed by the second side seam sealing machine 22, and the upper and lower ports of the product are heat-sealed by the second port sealing machine 23, and finally cut by the cutting mechanism 11; before the upper port of the product inner package is sealed, the Chinese medicine composition can fall from the upper port direction and enter the corresponding inner package range. When the product inner package continues to descend for a distance, it is sealed by the free second port sealing machine 23, thereby achieving the continuity of the inner packaging function.

[0043] In order to facilitate the removal of coils, Figure 9As shown, the coil support mechanism 7 provided by the present invention includes a support seat 71, a cantilever 72 is provided at the end of the support seat 71, a support opening 73 is provided on the cantilever 72, a support arm 74 is provided in the support opening 73, a roller shaft 75 is provided on one side of the support arm 74, a support shaft 76 near the top end thereof is provided on the other side of the support arm 74, and a pull plate 77 is provided at the end of the support shaft 76. Among them, the bottom surface of the support seat 71 is larger than the lower surface of the cantilever 72. In order to ensure the rationality of the coil installation space, the support seat 71 is installed below the discharge hopper 10, and the support seat 71 is fixed to the inner bottom of the chassis 8 by screws, bolts and other connecting parts, and the cantilever 72 extends to the support center of the coil by staggered extension; the roller shaft 75 is used to be inserted in the center of the coil, and the upper and lower sides of the roller shaft 75 have corresponding supports. For example, the cantilever 72 supports the bottom of the support arm 74, and the support shaft 76 and the pull plate 77 are hung on one side of the chassis 8 by hanging, so as to exert an upward pulling force on the support arm 74, and have a certain anti-overturning effect, so that the inner packaging cloth roll and the outer packaging paper roll have better stability, and can reduce the resistance of their free ends to being continuously pulled out, thereby improving the quality and efficiency of the discharge of this equipment.

[0044] like Figure 11 As shown, for spatial considerations, the inner packaging mechanism 2 and the outer packaging mechanism 3 are connected in a staggered front-to-back manner. To match this, the chute 9 includes a main chute section, which is connected to the cutting mechanism 11. Side chute sections are provided on the sides of the main chute section, which communicate with it and connect to the outer packaging guide plate 31. The bottom of the main chute section is an inclined surface, the end of which connects to the side chute section. The notch of the side chute section corresponds to the opening of the outer packaging guide plate 31, allowing the cut inner package to flow along the main and side chute sections into the inner opening of the outer packaging guide plate 31, and then into the outer packaging paper formed at the outer packaging station. To ensure that the inner package is not transferred into the outer packaging paper before the marking line is connected, the present invention provides a flap valve at the end of the chute 9. The flap valve keeps the inner package in the side chute section before the wire is connected, thereby improving the efficiency of its connection to the wire mark. After the inner package is connected to the line mark, the flap valve allows the inner package to slide down along the outer package guide plate 31, thereby ensuring that the inner package and the line mark enter the corresponding outer package at the same time.

[0045] The above description is merely a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any person skilled in the art may utilize the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields. However, any simple modification, equivalent change, and modification of the above embodiments made in accordance with the technical essence of the present invention without departing from the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
