The entire weighing process is controlled by a computer and completed automatically. It has the characteristics of fast weighing speed, high weighing accuracy, labor saving, manpower saving, simple operation and convenient maintenance. The quantitative packaging scale consists of a weighing unit, a trolley, a bag sewing and conveying device, a pneumatic system, a dust removal system and a quantitative packaging control instrument. Among them, the key component that affects the packaging speed and accuracy is the weighing unit, which includes a storage bin, a gate, a material cutting device, a scale body, a bag clamping device, a bracket and an electrical control device.
[0003] In the prior art, when using an automatic quantitative packaging scale to weigh packaging materials, in order to increase the loading rate, the automatic quantitative packaging scale usually uses a spiral conveying system to convey materials. Although the spiral conveying system can achieve the purpose of conveying materials, when conveying granular or highly viscous materials, the spiral conveying blades in the spiral conveying system will adhere to the materials, and the feeding amount of the automatic quantitative packaging scale cannot be accurately controlled, and the materials cannot be evenly introduced into the weighing area of the packaging scale, thereby affecting the accuracy of the packaging. Therefore, an automatic feeding mechanism for an automatic quantitative packaging scale is proposed to solve the above technical problems. Utility Model Content
[0004] In response to the shortcomings of the existing technology, the utility model provides an automatic feeding mechanism for an automatic quantitative packaging scale, which has the advantage of being able to feed evenly. It solves the problem that when conveying granular or highly viscous materials, the spiral conveying blades in the spiral conveying system will adhere to the material, making it impossible to accurately control the feeding amount of the automatic quantitative packaging scale, and thus making it impossible to evenly enter the weighing area of the packaging scale, thereby affecting the packaging accuracy.
[0005] To achieve the above-mentioned object, the present invention provides the following technical solutions: an automatic feeding mechanism for an automatic quantitative packaging scale, which is located on the packaging scale body and includes a feeding hopper provided on the packaging scale body, wherein the feeding hopper is provided with a feeding assembly for uniformly discharging materials;
[0006] The feeding assembly includes a buffer bin connected to the feed hopper, a drive module assembled on the packaging scale body, a turntable arranged on the output shaft of the drive module, a guide column arranged on the turntable, a push plate arranged on the buffer bin, a connecting rod arranged on the push plate, and a perforated plate arranged at the end of the connecting rod away from the push plate.
[0007] Furthermore, the buffer bin is in the shape of a rectangular parallelepiped with a hollow interior and a missing right side.
[0008] Furthermore, a guide hole for the connecting rod to pass through is formed on the buffer bin, and the guide hole is clearance-matched with the connecting rod.
[0009] Furthermore, a long hole for the guide column to pass through is formed on the perforated plate, and the guide column is slidably connected to the long hole.
[0010] Furthermore, a sealing plug for improving the sealing performance is provided on the buffer bin, and a through hole is formed on the sealing plug to fit the connection rod in a clearance.
[0011] Furthermore, the perforated plate is located on the front side of the turntable.
[0012] Furthermore, a vertical plate is provided on the packaging scale body, a guide sleeve is assembled on the vertical plate, and a limiting hole is formed on the guide sleeve to fit the connecting rod with a clearance.
[0013] Compared with the existing technology, the technical solution of this application has the following beneficial effects:
[0014] The automatic feeding mechanism for the automatic quantitative packaging scale is provided with a feeding assembly in the automatic quantitative packaging scale. By setting a driving module, after the driving module is started, the turntable and the guide column are driven to start rotating. The guide column performs an up and down reciprocating motion in the long strip hole provided in the perforated plate, and at the same time drives the perforated plate to perform a left and right reciprocating motion. The movement of the perforated plate drives the connecting rod and the push plate to perform a left and right reciprocating motion at the same time. With the left and right reciprocating motion of the push plate, the material dropped into the buffer bin by the feed hopper can be evenly pushed out of the buffer bin, thereby accurately controlling the feeding amount of the automatic quantitative packaging scale, so that the material can evenly fall on the weighing area of the packaging scale body, thereby solving the problem that when conveying granular or highly viscous materials, the material will adhere to the spiral conveying blades in the spiral conveying system, the feeding amount of the automatic quantitative packaging scale cannot be accurately controlled, and the material cannot evenly enter the weighing area of the packaging scale, thereby affecting the packaging accuracy.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] See also Figure 1 , an automatic feeding mechanism for an automatic quantitative packaging scale, has the advantage of being able to accurately control the feeding amount, so that the material enters the weighing area of the packaging scale evenly.
[0021] In this embodiment, an automatic feeding mechanism for an automatic quantitative packaging scale is located on a packaging scale body 1 and includes a feeding hopper 2 arranged on the packaging scale body 1. The feeding hopper 2 is provided with a feeding component 3 for uniform feeding.
[0022] The feeding assembly 3 includes a buffer bin 301 connected to the feed hopper 2, a driving module 302 assembled on the packaging scale body 1, a turntable 303 arranged on the output shaft of the driving module 302, a guide column 304 arranged on the turntable 303, a push plate 305 arranged on the buffer bin 301, a connecting rod 306 arranged on the push plate 305, and a perforated plate 307 arranged at the end of the connecting rod 306 away from the push plate 305.
[0023] It should be noted that a weighing sensor is installed on the packaging scale body 1, which is located below the buffer bin 301. In this application, it is used to weigh the material. The weighing sensor is a common accessory in automatic quantitative packaging scales in the prior art. Its working principle is a technology well known to technicians in the field of packaging scale technology and will not be described in detail in this article.
[0024] See also Figure 2-3 In order to ensure that the material enters the weighing area of the packaging scale body 1 evenly, the feeding assembly 3 in this embodiment includes a buffer bin 301 connected to the feed hopper 2, a driving module 302 assembled on the packaging scale body 1, a turntable 303 arranged on the output shaft of the driving module 302, a guide column 304 arranged on the turntable 303, a pusher plate 305 arranged on the buffer bin 301, a connecting rod 306 arranged on the pusher plate 305, and a perforated plate 307 arranged at the end of the connecting rod 306 away from the pusher plate 305.
[0025] It should be noted that the driving module 302 includes but is not limited to a speed regulating motor or a servo motor and other devices or structures that can rotate the turntable 303. It is sufficient to be able to rotate the turntable 303. Preferably, the driving module 302 in this application is a speed regulating motor. By adjusting the speed of the speed regulating motor, the feeding speed and feeding amount of the packaging scale body 1 can be controlled.
[0026] The shape of the buffer bin 301 is a rectangular parallelepiped with a hollow interior and a missing right side. The shape of the buffer bin 301 itself facilitates the falling of materials into the weighing area of the packaging scale body 1 .
[0027] A guide hole for the connecting rod 306 to pass through is formed on the buffer bin 301 , and the guide hole and the connecting rod 306 are clearance-matched.
[0028] The perforated plate 307 is formed with a long hole for the guide post 304 to pass through, and the guide post 304 is slidably connected to the long hole.
[0029] The buffer bin 301 is provided with a sealing plug for improving the sealing performance. The sealing plug is formed with a through hole that is gap-matched with the connecting rod 306 . The sealing plug plays a role in improving the sealing performance of the connection between the connecting rod 306 and the buffer bin 301 .
[0030] The perforated plate 307 is located on the front side of the turntable 303 .
[0031] A vertical plate is provided on the packaging scale body 1, and a guide sleeve is assembled on the vertical plate. A limiting hole is formed on the guide sleeve, which is clearance-matched with the connecting rod 306. The driving module 302 is assembled on the vertical plate, and the guide sleeve plays a role in limiting and guiding the connecting rod 306.
[0032] The working principle of the above embodiment is:
[0033] When the packaging scale body 1 is needed to weigh and package materials, the materials will first enter the feed hopper 2. At this time, the drive module 302 is started, and the output shaft of the drive module 302 starts to rotate, driving the turntable 303 to start rotating. The rotation of the turntable 303 drives the guide column 304 to start rotating. The guide column 304 moves in the long hole on the perforated plate 307 at this time. The perforated plate 307 reciprocates left and right with the rotation of the guide column 304. The movement of the perforated plate 307 drives the connecting rod 306 to reciprocate left and right at the same time. The movement of the connecting rod 306 drives the pusher plate 305 to reciprocate left and right. At this time, the pusher plate 305 reciprocates left and right in the buffer bin 301. As the pusher plate 305 moves, the material falling from the feed hopper 2 into the buffer bin 301 can be quantitatively pushed out of the buffer bin 301 and finally fall into the weighing area on the packaging scale body 1, so that the material evenly enters the weighing area of the packaging scale body 1, accurately controlling the feeding amount of the automatic quantitative packaging scale.
