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 in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear below, they only indicate that the upper, lower, left and right directions are consistent with the accompanying 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 of the following disclosure.

[0034] Examples, such as Figure 1-Figure 11As shown, a packaging device for preparing a Chinese medicine composition tea bag provided by the present invention comprises 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 set of coil support mechanisms 7 are provided at the supply ends of the inner packaging mechanism 2 and the outer packaging mechanism 3, and a tea hopper 1 is also provided above the inner packaging mechanism 2. The Chinese medicine tea material in the Chinese medicine tea bag can be conveyed by a chain bucket conveying mechanism, or can be weighed and discharged through a material tank with a valve. On this basis, the inner packaging mechanism 2, the outer packaging mechanism 3, the wire feeding mechanism 4, the label feeding mechanism 5 and the coil support mechanism 7 provided by the present invention are all arranged in a chassis 8, the chassis 8 is C-shaped and includes an upper cavity 81, a middle cavity 82 and a lower cavity 83 which are 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 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 with the inner packaging mechanism 2 and the outer packaging mechanism 3 is arranged between the two. The two sets of the coil support mechanism 7 are arranged side by side in the lower cavity 83, and a discharge hopper 10 is arranged 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 packaging cloth roll and the outer packaging paper roll are greater than the weight of the wire and the label paper, the installation space of the inner packaging cloth roll and the outer packaging paper roll is set in the lower cavity 83, and the space of the lower cavity 83 is larger than the space of the upper cavity 81, so that the difficulty of replacing the paper roll can be reduced. When replacing the material, just open the corresponding flip cover 85 to replace it, which is conducive to improving work efficiency. When the material ends of the inner packaging cloth roll and the outer packaging paper roll are pulled onto the corresponding inner packaging mechanism 2 and the outer packaging mechanism 3, the staff can 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 the outer packaging are carried out in a relatively closed environment, which is beneficial to improving the hygiene of the Chinese medicine composition tea bag and shortening the assembly line length of the inner packaging station and the outer packaging station. The inner packaging product delivered from 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 drive rollers 16 are arranged on the outer side of the outer packaging guide plate 31, and the end of the friction drive roller 16 is provided with a reduction motor 17 located on the outer side 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 the first side seam sealing machine 32 and the first port sealing machine 33 are arranged 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 led 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 delivery mechanism 5 provided by the present invention includes a paper roller 51 vertically connected to the rear wall of the chassis 8, a paper cutting roller 52 is arranged in the upper cavity 81, and a paper outlet slot 53 connected from the end of the upper cavity 81 to the outer packaging mechanism 3 is arranged in the discharging direction of the paper cutting roller 52, and a material shifting mechanism 12 hingedly connected to the paper outlet slot 53 is arranged on the back of the paper outlet slot 53. Among them, the paper roller 51 is used to load the label paper roll, and the free end of the label paper roll is pulled out to the paper cutting roller 52. A cutting knife is arranged on the roller surface of the paper cutting roller 52. The cutting knife can cut out a paper label after one rotation action, and the cut paper label is shifted into the paper outlet slot 53 by the paper cutting roller 52 and slides down along the paper outlet slot 53.

[0038] like Figure 5 and Figure 8 As shown, the interior of the middle cavity 82 is provided with a first point connection mechanism 13 that moves in a telescopic manner toward the paper outlet slot 53. The first point connection mechanism 13 is used to crimp the paper label and one end of the wire. The side of the material chute 9 is provided with a second point connection mechanism 14 that is used to crimp the other end of the wire to the inner packaging of the tea bag. The first point connection mechanism 13 is driven by a cylinder, and a dispensing head is used at its end, and the area of ​​the dispensing head is much larger than the end area of ​​the marking line. The dispensing head is connected to the glue source through a hose. Under the drive of the cylinder, the dispensing head can quickly contact the marking line. The dispensing point can be the end of the marking line or the front end of the marking line, thereby ensuring the quality and efficiency of the first point connection.

[0039] Furthermore, the interior of the paper outlet slot 53 is provided with two plate holes 54 spaced apart in an upper and lower direction, and a cutting board 55 connected to the paper outlet slot 53 is provided in the direction opposite to the plate hole 54, and the cutting 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 between the plate hole 54 and the cutting board 55, and the material shifting mechanism 12 includes a material shifting plate 121, and baffles 122 that alternately cooperate with the plate holes 54 are provided at both ends of the material shifting 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 shifting cylinder 123 is provided below the material shifting plate 121. On the path of the paper label sliding down, the telescopic end of the material-dispensing cylinder 123 descends, and the lower end of the material-dispensing 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-dispensing cylinder 123 is lifted up, and the upper end baffle 122 of the material-dispensing plate 121 is inserted into the upper plate hole 54. 4, on the one hand, it blocks the next paper mark that is about to slide down, and on the other hand, its cutting edge hits the anvil 55 to achieve the purpose of cutting the marking line. The previous paper mark is still kept on the lower baffle 122, and the other end of the marking line hangs down into the chute 9, and the marking line is pressed on the inner package by the second point connection structure; the material-dispensing cylinder 123 continues to extend, and the marking line can enter the outer packaging station with the inner package; after the material-dispensing 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, and the blowing mechanism 15 includes a blowing pipe 151 located in the middle cavity 82, and the blowing pipe 151 is used to blow one end of the wire material to the inner wall of one side of the material chute 9, and 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-digging mechanism 12 cuts off the marking line, the blowing pipe 151 provides assistance to the marking line to move downward, and enables it to be close to one wall of the material chute 9, which is conducive to improving the second point connection mechanism 14 to press the end of the marking line on the inner package of the product. The second point connection mechanism 14 can adopt a rapid hot pressing method, and the hot pressing end of the cylinder driver completes the telescopic action on the side of the material 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 of 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 a threading hole 44 is provided on the stepping traction roller 42. 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 enable the wire to be pulled out of the winding part for a certain length, and hang down from the plate hole 54 and the anvil 55, so that it has a controllable length and a sagging direction, thereby ensuring that the subsequent cutting of the wire mark is within a certain standard range.

[0042] like Figure 3 , Figure 5 and Figure 6 As shown, in order to improve the connection efficiency of the front and rear actions 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 outer side 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, the free second port sealing machine 23 is sealed, thereby achieving the continuity of the inner packaging function.

[0043] In order to facilitate the loading and unloading of coils, Fig. 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 close to 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 the equipment.

[0044] like Fig.11 As shown, for the sake of space coordination, the inner packaging mechanism 2 and the outer packaging mechanism 3 are connected in a front-to-back staggered manner. To match this, the chute 9 includes a main chute section, which is connected to the cutting mechanism 11. The side of the main chute section is provided with a side chute section that is connected to the main chute section and connected to the outer packaging guide plate 31. The bottom of the main chute section is an inclined surface, and the end of the inclined surface is connected to the side chute section. The notch of the side chute section corresponds to the open opening of the outer packaging guide plate 31, so that the cut inner package can enter the inner opening of the outer packaging guide plate 31 along the main chute section and the side chute section, and then enter the outer packaging paper formed in the outer packaging station. In order to ensure that the inner package is not transferred into the outer packaging paper before the marking line is connected, the present invention is provided with a flap valve at the end of the chute 9. The flap valve can keep the inner package in the side chute section before the wire is connected, thereby improving its connection efficiency with the wire mark. After the inner package is connected with 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 carrying the line mark enters the corresponding outer package at the same time.
