Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of feeding mechanisms, specifically a feeding mechanism for a vertical packaging machine. Background Technology
[0002] Vertical packaging machines are automatic packaging equipment widely used in the food, pharmaceutical, and cosmetic industries. They are mainly used to package products according to certain specifications and methods. During operation, materials are poured into the machine through the feed inlet at the top, and the machine packages the materials into bags. A search reveals that Chinese patent publication number CN222272472U discloses a feeding mechanism for a vertical packaging machine, including a main body. A feed hopper is fixedly installed at the top center of the main body, and a discharge hopper is located at the bottom center. Several support rods are welded to the outer surface of the main body, and a distribution bin is fixedly installed at the top of each support rod. A cross-shaped partition is fixedly connected to the bottom center of the inner wall of the distribution bin, dividing the bin into multiple placement slots. A discharge pipe is opened through the bottom center of each placement slot. The distribution bin also has an opening and closing mechanism to control the discharge from the discharge pipe.
[0003] While the above technical solutions achieve the effect of facilitating the packaging of various materials and improving the overall packaging efficiency of the packaging machine, they lack quantitative accuracy, rely on the gravity of the material to discharge through the discharge pipe, are greatly affected by the flowability of the material, and are prone to blockage and material adhesion to the inner wall, which affects the packaging effect. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a feeding mechanism for a vertical packaging machine, which solves the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a feeding mechanism for a vertical packaging machine, comprising a base and a vertical packaging machine fixedly installed on the top of the base, a first bracket fixedly installed on the top of the base, an mounting plate fixedly installed on the top of the first bracket, a second bracket fixedly installed on the top of the mounting plate, a plurality of storage tanks fixedly installed on the top of the second bracket, a mixing tank connected to the bottom of the storage tanks fixedly installed in the middle of the first bracket, and a feeding and cleaning mechanism is installed through the top of both the storage tanks and the mixing tank;
[0006] The feeding and cleaning mechanism includes a motor, which is fixedly installed on the top of the corresponding storage tank and mixing tank. The output shaft of the motor is fixedly connected to a rotating shaft through a coupling, and a spiral conveying blade is fixedly connected to the outer surface of the rotating shaft.
[0007] Preferably, two connecting rods are symmetrically fixedly connected to the outer surface of the rotating shaft, and a scraper is fixedly connected to the other end of the connecting rod. The scraper contacts the inner wall of the corresponding storage tank and mixing tank, which can scrape the material from the inner wall of the storage tank and mixing tank to avoid material residue.
[0008] Preferably, both the storage tank and the mixing tank are fixedly connected to a discharge pipe at their bottom ends. The discharge pipe located at the bottom of the storage tank is connected to the interior of the mixing tank, and the discharge pipe located at the bottom of the mixing tank is connected to the feed end of the vertical packaging machine to facilitate material falling.
[0009] Preferably, the spiral conveying blade extends into the interior of the corresponding feed pipe to facilitate spiral conveying of materials.
[0010] Preferably, a feed pipe is fixedly installed on the top of the storage tank to facilitate the addition of materials to the storage tank.
[0011] Preferably, a controller is fixedly installed on one side of the upper surface of the base to facilitate the control of each motor.
[0012] This utility model provides a feeding mechanism for a vertical packaging machine. It has the following beneficial effects:
[0013] The feeding mechanism of this vertical packaging machine replaces the original integrated placement slots divided by cross partitions with independent storage tanks in a ring array. This breaks through the limitation of cross partitions on the types and quantities of materials, and the number of storage tanks can be flexibly increased or decreased according to needs, adapting to more diverse material packaging scenarios.
[0014] The feeding and cleaning mechanism not only enables high-precision quantitative control and precise adjustment of the feeding amount, ensuring packaging accuracy without being affected by material flowability, but also removes residual contamination and cleans adhering materials. The spiral conveyor provides active driving force, avoiding blockages and speed fluctuations caused by gravity feeding, making the subsequent packaging process of the packaging machine more stable.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example:
[0023] like Figure 1 and Figure 2 As shown, a feeding mechanism for a vertical packaging machine includes a base 1 and a vertical packaging machine 2 fixedly installed on the top of the base 1. A first bracket 3 is fixedly installed on the top of the base 1, an mounting plate 4 is fixedly installed on the top of the first bracket 3, a second bracket 5 is fixedly installed on the top of the mounting plate 4, and a plurality of storage tanks 6 are fixedly installed on the top of the second bracket 5. A mixing tank 7 connected to the bottom of the storage tank 6 is fixedly installed in the middle of the first bracket 3. Both the storage tank 6 and the mixing tank 7 are fixedly connected to the bottom end of a discharge pipe 9. The discharge pipe 9 located at the bottom of the storage tank 6 is connected to the interior of the mixing tank 7, and the discharge pipe 9 located at the bottom of the mixing tank 7 is connected to the feed end of the vertical packaging machine 2. A feed pipe 10 is fixedly installed on the top of the storage tank 6.
[0024] The original integrated placement slots separated by cross-shaped partitions have been replaced with independent storage tanks 6 arranged in a ring array. This breaks through the limitations of cross-shaped partitions on the types and quantities of materials, and the number of storage tanks 6 can be flexibly increased or decreased according to needs, adapting to more diverse material packaging scenarios.
[0025] like Figures 1 to 5 As shown, a feeding and cleaning mechanism 8 is installed through the top of both the storage tank 6 and the mixing tank 7. The feeding and cleaning mechanism 8 includes a motor 81, which is fixedly installed on the top of the respective storage tank 6 and the mixing tank 7. The output shaft of the motor 81 is fixedly connected to a rotating shaft 82 through a coupling. A spiral conveying blade 83 is fixedly connected to the outer surface of the rotating shaft 82. The spiral conveying blade 83 extends into the interior of the corresponding discharge pipe 9.
[0026] The rotation of motor 81 drives the rotating shaft 82 and the spiral conveyor blade 83 to rotate. The feeding amount can be precisely adjusted by controlling the rotation speed of the spiral conveyor blade 83 (e.g., the feeding amount is fixed per revolution). This solves the problems of the difficulty in accurately controlling the opening and closing degree of the movable baffle and the influence of material flowability on the feeding amount in the prior art. In addition, the rotation of the spiral conveyor blade 83 provides a continuous driving force, which can force the conveying of low flowability materials and effectively avoid blockage. At the same time, the uniform speed characteristic of the spiral conveyor can ensure the stable feeding speed and avoid the fluctuation of "fast at first and slow later" when discharging by gravity, making the subsequent packaging process (such as sealing and metering) of the main body of the packaging machine more stable.
[0027] Two connecting rods 84 are symmetrically fixedly connected to the outer surface of the rotating shaft 82. A scraper 85 is fixedly connected to the other end of the connecting rod 84. The scraper 85 is in contact with the inner wall of the corresponding storage tank 6 and mixing tank 7.
[0028] When the rotating shaft 82 rotates, it can also drive the connecting rod 84 and the scraper 85 to rotate. The scraper 85 rotates synchronously with the screw conveyor blade 83, which can remove the adhering material and avoid residual material.
[0029] A controller 11 is fixedly installed on one side of the upper surface of the base 1. The controller 11 facilitates the control of the corresponding motor 81. In addition, a flow meter can also be installed in this technical solution for accurate measurement. Controlling by the controller 11 is a common technical means used by those skilled in the art and belongs to the prior art.
[0030] Working principle: During use, each material enters the corresponding storage tank 6 through the feed pipe 10. The controller 11 controls the corresponding motor 81 to rotate, which can drive the rotating shaft 82, the spiral conveyor blade 83 and the scraper 85 to rotate. The rotation of the spiral conveyor blade 83 can convey the material in a spiral manner. The feeding amount can be precisely adjusted by controlling the rotation speed of the spiral conveyor blade 83 (such as a fixed feeding amount per revolution). This solves the problems of the difficulty in accurately controlling the opening and closing degree of the movable baffle and the influence of material flowability on the feeding amount in the existing technology. In addition, the rotation of the spiral conveyor blade 83 provides a continuous driving force, which can force the conveying of low flowability materials and effectively avoid blockage. At the same time, the uniform speed characteristic of the spiral conveyor can ensure the stable feeding speed and avoid the fluctuation of "fast at first and slow later" when discharging by gravity, making the subsequent packaging links (such as sealing and metering) of the main body of the packaging machine more stable.
[0031] The scraper 85 rotates synchronously with the screw conveyor blade 83, which can remove the adhering material and avoid residual material.
[0032] Finally, the materials are packaged inside the vertical packaging machine 2.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
