DETAILED DESCRIPTION

[0054] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0055] Example 1

[0056] An automatic weighing and packaging device for Chinese herbal medicine slices, such as Figure 1-Figure 3 As shown, it includes a base 1, a moving component 2 is installed on the upper left side of the base 1, a blanking frame 3 is fixedly installed on the upper left side of the base 1 and located at the rear side of the moving component 2, a cover plate 4 is movably installed on the top of the blanking frame 3, and the top of the cover plate 4 is provided with a pull handle, a first cylinder 5 is installed on the upper side of the moving component 2, a first adsorption component 6 is installed on the telescopic rod of the first cylinder 5, and a second adsorption component 7 is installed on the front side of the first adsorption component 6, which is used to cooperate with the first adsorption component 6 to adsorb and expand the packaging bag, and the first adsorption component and the second adsorption component both use airflow adsorption to achieve adsorption connection of the packaging bag, a weighing mechanism 8 is arranged inside the blanking frame 3, which is used to quantitatively weigh the materials to be packaged, and a sealing mechanism 9 is arranged on the upper right side of the base 1, which is used to quickly hot-melt seal the packaged materials.

[0057] It should be noted that after the production and processing of Chinese herbal medicines, they need to be packaged according to the quantitative quantity. At this time, the present device can be used for auxiliary operation. First, the cover plate 4 is opened, and the Chinese herbal medicines to be packaged are placed in the feeding frame 3. Then, the weighing mechanism 8 is used to weigh the herbal medicines to be packaged each time. After reaching the standard weight, the herbal medicines are guided downward and discharged. At the same time, the packaging bag is fitted with the first adsorption component 6 and the second adsorption component 7 so that the upper part of the packaging bag is opened as a whole. As the herbal medicines enter the packaging belt, the weighing mechanism 8 will stop feeding. At this time, the moving component 2 is operated to drive the first adsorption component 6 and the second adsorption component 7 to move slightly, so that the loaded packaging bag moves to the sealing mechanism 9. Finally, the sealing mechanism 9 is operated to perform hot-melt sealing on the packaging bag.

[0058] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the weighing mechanism 8 includes a second cylinder 81, a total of two, which are respectively installed on the left and right sides of the unloading frame 3, a placing plate 82 is slidably installed between the telescopic rods of the second cylinder 81, and is used to carry and support the Chinese herbal medicine pieces, a first spring 83 is respectively sleeved on the placing plate 82, and is connected to the placing plate 82 and the telescopic rod of the second cylinder 81, a weighing plate 85 is installed on the placing plate 82, and is used to quantitatively weigh the Chinese herbal medicine pieces to be packaged, and a heating plate 86 is installed between the placing plate 82 and the weighing plate 85 , used to heat the Chinese herbal medicine slices and keep them dry. The power supply component 84 is installed on the shelf at the bottom of the blanking frame 3 and is electrically connected to the weighing plate 85 and the heating plate 86. There are two baffles 87, which are rotatably arranged inside the blanking frame 3 to block and guide the Chinese herbal medicine slices. There are four limit members 88, two in each group, which are arranged on the left and right sides of the blanking frame 3. The sliding member 89 is slidably arranged on the corresponding limit member 88, and is used to cooperate with the limit member 88 to clamp and limit the adjacent baffles 87.

[0059] It should be noted that when weighing the materials, first, the baffles 87 are flipped upward at a certain angle so that the two baffles 87 are in a parallel state, and then the baffles 87 are limited and locked by relying on the cooperation of the sliding member 89 and the limit member 88. After the operation is completed, the Chinese herbal medicine pieces are put in normally, so that the baffles 87 can support the materials, and then the baffles 87 are manually controlled to flip so that the medicine pieces can fall on the weighing plate 85, and the heating plate 86 is started to dry the medicine pieces. When the medicine pieces reach the packaging weight, the baffles 87 are flipped and closed to prevent the medicine pieces from being unloaded. At the same time, the telescopic rod of the second cylinder 81 is controlled to move to drive the placement plate 82 to move, so that the medicine pieces on the weighing plate 85 can directly fall into the opened packaging bag, thereby achieving the effect of quantitative weighing and packaging. After the operation is completed, the telescopic rod of the second cylinder 81 is controlled to reset, so that the placement plate 82 drives the weighing plate 85 to reset, and the lower part of the unloading frame 3 is blocked again.

[0060] like Figure 1 and Figure 7 As shown, the sealing mechanism 9 includes a mounting frame 91, which is mounted on the upper right side of the base 1. There are two heating elements 92, which are mounted on the top of the mounting frame 91 in a front-to-back symmetrical state. There are four driving wheels 93, which are rotatably mounted on the left and right parts of the mounting frame 91 for pushing the packaging bag. There are two first driving motors 94, which are respectively mounted on the rear side of the mounting frame 91. There are six gears 95, four of which are connected to the driving wheels 93, and the other two are respectively connected to the corresponding output shafts of the first driving motors 94, and adjacent gears 95 are meshed with each other.

[0061] It should be noted that as the Chinese herbal medicine pieces are put into bags, the moving component 2 will control the first adsorption component 6 and the second adsorption component 7 to move to the right, so that the packaging bag is guided to the left side of the sealing mechanism 9, and then the first drive motor 94 is started. The rotation of the output shaft of the first drive motor 94 will drive the corresponding gear 95 to rotate, so that the front and rear symmetrical driving wheels 93 begin to rotate in opposite directions, and then the packaging bag is sent into the gap between the heating elements 92, and finally the packaging bag is hot-melt sealed by the heating element 92. The entire process is automated, the operating efficiency is higher, and automatic loading and unloading of the packaging bag can be realized.

[0062] Example 2

[0063] On the basis of Example 1, Figure 1 , Figure 8 and Fig. 9As shown, it also includes a feeding mechanism 10, which includes a limiting seat 101. The limiting seat 101 is connected to the middle position of the left and right sides of the feeding frame 3 by bolts. The limiting seat 101 is slidably connected with a moving part 102. The moving parts 102 are slidably connected to the corresponding baffles 87. The moving parts 102 are connected to the corresponding telescopic rods of the first cylinder 5. Two fixed columns 103 are connected to the left and right sides of the feeding frame 3. A second spring 104 is rotatably connected between the fixed column 103 and the adjacent baffle 87.

[0064] It should be noted that as the placement plate 82 moves backward, the telescopic rod of the first cylinder 5 will drive the movable member 102 to move backward synchronously, so that the movable member 102 pulls the baffle 87 to flip, thereby achieving the effect of automatically closing the baffle 87. In this process, the second spring 104 will be deformed due to the involvement. When the discharge is completed and weighing needs to continue, as the telescopic rod of the first cylinder 5 is reset, the baffle 87 will be assisted in opening under the action of the second spring 104, so as to prevent the baffle 87 from getting stuck and difficult to flip normally.

[0065] like Figure 1 and Fig.10 As shown, it also includes a vibration mechanism 11, which includes a second drive motor 111. The second drive motor 111 is installed on the front side of the blanking frame 3. An eccentric wheel 112 is connected to the output shaft of the second drive motor 111. The front side of the blanking frame 3 is connected to a cover frame 113, and the second drive motor 111 is located inside the cover frame 113.

[0066] It should be noted that the second drive motor 111 is started synchronously when discharging, and the rotation of the output shaft of the second drive motor 111 drives the eccentric wheel 112 to rotate, thereby generating a vibration deviation, so that the discharge frame 3 can maintain vibration to avoid material blockage.

[0067] like Figure 1 and Fig.11 As shown, a protective mechanism 12 is also included, and the protective mechanism 12 includes a first protective frame 121. The first protective frame 121 is connected to the heating element 92 on the rear side, and the first protective frame 121 is connected to the heating element 92 on the front side. The first protective frame 121 and the second protective frame 122 are both used to protect the heating element 92. The first protective frame 121 and the second protective frame 122 are detachable connection structures.

[0068] like Figure 1 and Fig.11 As shown, it also includes a moving mechanism 13, which includes a rotating roller 131. The left and right parts of the mounting frame 91 are both rotatably connected to the rotating rollers 131, and a conveyor belt 132 for assisting the transportation of packaging bags is wound between the rotating rollers 131.

[0069] It should be noted that when the packaging bag is loaded and conveyed to the right to the sealing mechanism 9, the bottom of the packaging bag will contact the conveyor belt 132, and the conveyor belt 132 will be driven by the movement of the packaging bag, thereby reducing the friction that the packaging bag may encounter during the movement, making the movement of the packaging bag smoother and avoiding damage to the bottom of the packaging bag.

[0070] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
