Description

Technical Field

[0001] The utility model relates to the technical field of grain packaging, in particular to a grain packaging continuous weighing device. Background Art

[0002] When packaging grains, they are usually filled inside vacuum bags. In order to extend the shelf life of the grains, the vacuum bags are evacuated. The resulting grains are usually square finished products with higher hardness, higher sealing performance and higher quality. When inspecting the grains, they need to be weighed and tested to verify the quality of the finished products to be released.

[0003] For example, in the patent document with application number: 201921335044.4, a continuous weighing device for melon seeds packaging is disclosed, and the setting of the weighing sensor is specifically disclosed, that is, the melon seeds transported on the conveyor belt are weighed by the weighing sensor under the conveyor belt, and the weighing quality is displayed on the display screen.

[0004] In the above technical solution, when the packaged grains are weighed, the grain packages may be impacted when they fall and may have sharp parts on the mechanical equipment when they enter the weighing sensor, which may affect the sealed grain packages and cause air leakage. However, if the grain packages are not weighed, some grain packages may contain defective products that do not meet the weight standards, which may affect the reputation of the product when it is sold. Utility Model Content

[0005] The technical problem solved by the utility model is to solve the problems in the prior art that, when grains are transferred from a conveying device to a weighing device, the grain packaging may generate impact force and the grain packaging may contact sharp parts to cause air leakage.

[0006] The utility model can be implemented through the following technical scheme: a continuous weighing device for grain packaging, comprising a transmission component and a weighing component, wherein the output end of the transmission component acts on the weighing component, and a receiving component for buffering the grain packaging is arranged between the weighing component and the transmission component.

[0007] A further technical improvement of the utility model is that the receiving component includes a first buffer component for initially buffering the grain packaging from the conveying component and a second buffer component for buffering the grain packaging direction from the first buffer component, and the second buffer component is located at the input end of the weighing component.

[0008] A further technical improvement of the utility model is that the first buffer assembly includes an elastic arc plate, the elastic arc plate is fixed on the connecting inclined plate, and a filling liquid is filled between the connecting inclined plate and the elastic arc plate.

[0009] A further technical improvement of the utility model is that the second buffer assembly includes a supporting slide plate, a fixed arc plate is fixed to the output end of the first buffer assembly, and a supporting slide plate for receiving the grain packaging is provided on the fixed arc plate in an inclined and sliding manner.

[0010] A further technical improvement of the utility model is that a supporting slide bar is fixed to the side of the supporting slide plate, the supporting slide bar is slidably connected to the fixed arc plate, and a supporting spring is installed between the end of the supporting slide bar and the fixed arc plate.

[0011] A further technical improvement of the utility model is that the supporting slide plate comprises a bottom plate, on which a buffer rubber for buffering the cereal packaging is fixed.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The present application installs a receiving assembly for buffering the grain packaging at the output end of the conveying assembly, so that the grain packaging that passes through the receiving assembly and falls onto the weighing assembly can be fully buffered, thereby preventing the grain packaging from directly hitting the weighing assembly, or preventing the grain packaging from contacting sharp parts during transportation, ensuring that the vacuum bag of the grain packaging will not leak easily, thereby ensuring the integrity of the grain packaging and making the finished grain packaging of higher quality.

[0014] 2. The present application uses the edge of the grain package to contact the elastic arc plate and impact the elastic arc plate. At this time, the viscous glue and the elastic arc plate are used for preliminary cushioning, and the grain package continues to fall on the second cushioning component due to inertia. The elastic arc plate will rebound and return to its original position due to its own memory, which is convenient for cushioning the next group of grain packages, thereby realizing continuous weighing of the grain packages.

[0021] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0022] See also Figure 1-4 As shown, a continuous weighing device for grain packaging includes a frame, on which a weighing component 1 and a conveying component 3 are arranged, wherein the conveying component 3 is used to convey the packaged grain packages until they are conveyed to the position of the weighing component 1 for weighing and determination, and good products and defective products are placed, thereby ensuring the quality of the grain packages obtained after production and ensuring that the weight of the grain packages to be sold reaches an acceptable level.

[0023] In order to achieve the stability of the grain package when it passes through the conveying component 3 and reaches the weighing component 1, that is, to avoid the problem of air leakage caused by the grain package under a large impact, and to avoid the problem of air leakage caused by the grain package contacting the sharp parts of the machine, a receiving component 2 is adopted in the present application, so that the grain package is buffered by the receiving component 2, and the grain package can be directly transported to the position of the weighing component 1 for weighing, and after weighing, the grain package only needs to be taken out for packaging to be sold.

[0024] Therefore, the receiving component 2 in the present application includes a multi-stage buffer component, that is, the receiving support plate 21 is first installed at the output end of the conveying component 3, that is, the grain package transported by the conveying component 3 first falls on the receiving support plate 21, and at this time the grain package is buffered by the first buffer component on the receiving support plate 21, so that the first buffer component protects the grain package to avoid problems such as collision caused by the grain package contacting sharp parts; then, after being guided and buffered by the first buffer component, the grain package falls to the position of the second buffer component, and the second buffer component is used to guide the grain package again, which can not only realize the falling of the grain package, but also realize the grain package falling to the position of the weighing component 1 for weighing.

[0025] Specifically, the first buffer component includes a connecting inclined plate 22, on which an elastic arc plate 210 is fixed, wherein the elastic arc plate 210 is made of rubber material, wherein the elastic arc plate 210 and the connecting inclined plate 22 form a filling cavity, wherein the filling cavity is filled with a filling liquid 29, wherein the filling liquid 29 is made of a viscous glue. When in use, the edge of the grain package first contacts the elastic arc plate 210 and collides with the elastic arc plate 210. At this time, the viscous glue and the elastic arc plate 210 are used for preliminary buffering, and the grain package continues to fall on the second buffer component due to inertia. The elastic arc plate 210 has its own memory, so it will rebound and return to its original position, so as to facilitate buffering for the next group of grain packages. However, in this process, the surface of the elastic arc plate 210 needs to be replaced regularly to prevent the filling liquid 29 from being broken and flowing out.

[0026] As a further embodiment of the present application, the second buffer component includes a supporting slide 28. Specifically, a fixed arc plate 23 is fixed at the end of the connecting inclined plate 22, wherein a supporting slide 28 is slidably arranged on the fixed arc plate 23, wherein the supporting slide 28 is inclined relative to the horizontal plane, so when the grain package falls on the supporting slide 28, the end of the grain package first slides along the direction of the fixed arc plate 23, and when it contacts the supporting slide 28, the moving direction of the grain package is gradually deflected by utilizing the tilting effect of the supporting slide 28, so that the grain package enters the weighing component 1 with a relatively gentle arc, thereby achieving another buffering effect on the grain package.

[0027] In the present application, since the support slide 28 moves longitudinally, when the cereal package falls and contacts the support slide 28, a downward force is applied to the support slide 28, causing the support slide 28 to move slightly longitudinally under the action of the cereal package, thereby buffering the downward impact force of the cereal package.

[0028] The supporting slide plate 28 is fixedly mounted on the supporting slide rod 26, wherein the supporting slide rod 26 is slidably mounted on the fixed arc plate 23, wherein a limiting plate 25 is fixed to one end of the fixed arc plate 23 away from the supporting slide plate 28, wherein a supporting spring 24 is installed between the limiting plate 25 and the fixed arc plate 23 for realizing longitudinal buffering of the supporting slide plate 28, wherein both ends of the supporting spring 24 are respectively located on the limiting plate 25 and the fixed arc plate 23.

[0029] During this process, the support slide plate 28 performs a slight tilt movement, causing the support slide rod 26 to slide tiltedly. At this time, the limit plate 25 is away from the fixed arc plate 23, so that the support spring 24 is subjected to a tensile force, that is, the support slide plate 28 can cushion the downward impact force of the grain package.

[0030] Since the upper surface of the support slide 28 may be relatively hard, the cereal package dropped onto the support slide 28 may be bumped, so the support slide 28 includes a bottom plate 211, wherein the bottom plate 211 is fixedly connected to the support slide bar 26, wherein a buffer rubber 212 is fixed to the end of the bottom plate 211 away from the support slide bar 26, that is, the buffer rubber 212 is used to support the cereal package, even if the sharp parts of the cereal package contact the buffer rubber 212, it will not affect the vacuum environment of the cereal package, thereby effectively protecting the vacuum of the cereal package.

[0031] Connecting rollers 27 are evenly arranged at the output end of the supporting spring 24, wherein the connecting rollers 27 and the frame are rotatably connected. When the grain packaging bag falls on the connecting rollers 27, the connecting rollers 27 can be used to buffer it and reduce the friction force when it moves to the position of the weighing component 1.

[0032] When the utility model is in use, when the grain package moves from the conveying component 3 to the position of the weighing component 1, it needs to be buffered by the receiving component 2, that is, the edge of the grain package first contacts the elastic arc plate 210, and the elastic arc plate 210 is impacted. At this time, the viscous glue and the elastic arc plate 210 are used for preliminary buffering, and the grain package continues to fall on the second buffer component due to inertia. The elastic arc plate 210 will rebound due to its own memory and return to its original position, which is convenient for buffering the next group of grain packages. However, in this process, the surface of the elastic arc plate 210 needs to be replaced regularly to prevent the filling liquid 29 from being broken and flowing out.

[0033] When the second buffer assembly is in use, the end of the grain package first slides down along the direction of the fixed arc plate 23. When it contacts the supporting slide plate 28, the moving direction of the grain package is gradually deflected by utilizing the tilting effect of the supporting slide plate 28, so that the grain package enters the weighing assembly 1 with a relatively gentle arc, thereby achieving another buffering effect on the grain package. In this process, since the supporting slide plate 28 moves longitudinally, when the grain package falls and contacts the supporting slide plate 28, a downward force is applied to the supporting slide plate 28, so that the supporting slide plate 28 moves slightly longitudinally under the action of the grain package, and at this time, the downward impact force of the grain package is buffered.

[0034] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
