Description

Technical Field

[0001] This utility model relates to the field of packaging production technology, and in particular to a rapid checkweighing and diversion device. Background Technology

[0002] During the packaging production process, it is often necessary to weigh and sort the products to be packaged or already packaged. When the weight of a product is within a set range, the product is determined to be good and is placed into a designated container. When the weight of a product exceeds the set range, the product is determined to be defective and is placed into another designated container.

[0003] In related technologies, in order to improve production efficiency, equipment with weighing and sorting functions has emerged. However, since both the weighing and sorting steps require a certain amount of time, the next product arrives before the previous product has been sorted, resulting in waiting and extremely low efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, one of the objectives of this utility model is to provide a rapid checkweighing and sorting device that can quickly complete the weighing and sorting of products without waiting, thereby improving packaging production efficiency.

The sorting guide is provided with a first unloading plate that connects to the lower end of the first door panel and a second unloading plate that connects to the lower end of the second door panel. The first unloading plate of one sorting guide is adjacent to the second unloading plate of the other sorting guide to define a first discharge channel for outputting good products.

[0013] In some embodiments of this utility model, the sorting guide includes a front end plate and a rear end plate arranged in parallel, a first unloading plate and a second unloading plate are connected between the front end plate and the rear end plate, the upper end of the first unloading plate and the upper end of the second unloading plate are connected, and the lower end of the first unloading plate and the lower end of the second unloading plate are opposite to each other.

[0014] In some embodiments of this utility model, both the front end plate and the rear end plate are inclined forward from top to bottom.

[0015] In some embodiments of this utility model, the lower edges of the front and rear side panels of the hopper are both "V" shaped. The front and rear sides of the first and second door panels are respectively provided with bent plate portions that are rotatably connected to the front and rear side panels of the hopper.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Reference Figures 1 to 6 This utility model discloses a rapid checkweighing and diversion device, comprising: a frame 100, on which a guide channel component 200 is movably disposed, the guide channel component 200 having a vertically penetrating material conveying channel 210 inside; at least two hoppers 300 disposed below the guide channel component 200, each hopper 300 having a vertically penetrating storage cavity 310, and each hopper 300 having a first door panel 320 and a second door panel 330 movably disposed opposite each other. The second door panel 330 is inclined to form a "V" shape to close the lower port of the storage cavity 310; the weighing module 400 is connected to the hopper 300; the first drive mechanism 500 is connected to the guide channel 200 and is used to drive the lower end of the conveying channel 210 to move to align with the upper port of the storage cavity 310 one by one; the second drive mechanism 600 is used to drive the first door panel 320 or the second door panel 330 to move to open the lower port of the storage cavity 310.

[0032] Products requiring checkweighing and sorting enter the guide channel component 200 one by one. After the products enter the storage chamber 310 of one of the hoppers 300 along the conveying channel 210, the first drive mechanism 500 drives the guide channel component 200 to move to align with the upper port of the storage chamber 310 of another hopper 300. Another product can then enter the other hopper 300 along the conveying channel 210. At the same time, the weighing module 400 weighs the previous product. The second drive mechanism 600 selectively controls the opening of the first door panel 320 or the second door panel 330 based on the weight data, thereby unloading the product in different paths. The weighing and sorting of products can be completed quickly without waiting, improving packaging production efficiency. It should be noted that, since the first door panel 320 and the second door panel 330 are inclined to form a "V" shape to close the lower port of the storage cavity 310, when the first door panel 320 is opened, the product can be discharged along the slope of the second door panel 330 towards the direct downward direction of the first door panel 320, and when the second door panel 330 is opened, the product can be discharged along the slope of the first door panel 320 towards the direct downward direction of the second door panel 330.

[0033] See Figure 1 and Figure 3 In some embodiments of this utility model, two hoppers 300 are arranged side by side on the frame 100, and the guide channel component 200 is rotatably arranged on the frame 100 about a horizontal axis. The first drive mechanism 500 drives the guide channel component 200 to reciprocate so that the material conveying channel 210 is alternately aligned with the upper port of the two storage cavities 310. Taking two hoppers 300 spaced approximately apart as an example, when the first drive mechanism 500 drives the guide channel component 200 to align with the left storage chamber 310, the product enters the left hopper 300. Then, the first drive mechanism 500 drives the guide channel component 200 to align with the right storage chamber 310, and another product can enter the other hopper 300. At the same time, the weighing module 400 weighs the previous product, and the second drive mechanism 600 selectively controls the first door panel 320 or the second door panel 330 to open based on the weight data. When the product is discharged, the first drive mechanism 500 drives the guide channel component 200 again to align with the left storage chamber 310, thereby realizing continuous product weighing and diversion.

[0034] See Figure 1 and Figure 3In some embodiments of this utility model, the first drive mechanism 500 includes a first motor 510, a first crank 520 connected to the output shaft of the first motor 510, and a connecting rod 530 rotatably connected to the end of the first crank 520. The end of the connecting rod 530 away from the first crank 520 is rotatably connected to the lower part of the guide channel component 200. The two opposite sidewalls of the upper part of the guide channel component 200 are respectively connected to the frame 100 through a rotating shaft assembly 700. The first drive mechanism 500 with the above structure constitutes a planar four-bar linkage. The two times when the first crank 520 and the connecting rod 530 are collinear correspond to the positions of the two maximum rotation angles of the guide channel component 200, so that the guide channel component 200 can pause briefly when aligned with the two hoppers 300 to facilitate the smooth entry of the product into the corresponding storage chamber 310.

[0035] See Figure 2 and Figure 3 In some embodiments of this utility model, in order to improve the smoothness and stability of the rotation of the guide channel component 200 relative to the frame 100, the rotating shaft assembly 700 includes a shaft component 710 fixedly disposed on the side wall of the guide channel component 200, a bearing inner sleeve 720 through which the shaft component 710 passes and is fixed, and a bearing outer sleeve 730 rotatably disposed outside the bearing inner sleeve 720.

[0036] See Figure 2 In some embodiments of this utility model, the frame 100 is provided with a guide rail groove 110 extending in a straight line between the two hoppers 300. The two opposite sidewalls of the guide channel component 200 are respectively provided with a support 800 corresponding to the rotating shaft assembly 700. The bearing outer sleeve 730 is formed with a mounting seat 740, which is fixedly mounted on the support 800. The support 800 has mounting holes opposite to the guide rail groove 110. A bolt assembly is connected between the mounting hole and the guide rail groove 110 to adjust the position of the guide channel component 200. It is understood that the size of the hopper 300 and the relative positions of its various parts need to be adjusted according to the different sizes of the products to be weighed and sorted. When the bolt assembly is loosened, the mounting hole on the support 800 moves along the guide rail groove 110. After the guide channel component 200 is adjusted to the correct position, the bolt assembly is tightened.

[0037] See Figure 1 and Figure 6In some embodiments of this utility model, a sorting guide 900 is installed below each of the two hoppers 300. The sorting guide 900 has a first unloading plate 910 that connects to the lower end of the first door panel 320 and a second unloading plate 920 that connects to the lower end of the second door panel 330. The first unloading plate 910 of one sorting guide 900 and the second unloading plate 920 of the other sorting guide 900 are adjacent to each other, defining a first discharge channel for outputting good products. It should be noted that when the first door panel 320 is opened, the product moves downwards along the slope of the second door panel 330. After the product leaves the second door panel 330, it is still a considerable distance from the container where the product is stored. The arrangement of the first unloading plate 910 and the second unloading plate 920 can guide the product towards the container for unloading, preventing it from falling and damaging itself. Moreover, generally speaking, the majority of products are of acceptable weight, and the first discharge channel formed by the areas where the two sorting guides 900 are close to each other supports a large flow rate of discharge.

[0038] See Figure 6 In some embodiments of this utility model, in order to prevent the product from detaching from the first unloading plate 910 and the second unloading plate 920 during downward movement, the sorting guide 900 includes a front end plate 930 and a rear end plate 940 arranged in parallel. The first unloading plate 910 and the second unloading plate 920 are connected between the front end plate 930 and the rear end plate 940. In order to prevent the product from being discharged in the wrong direction when diverting the product, the upper end of the first unloading plate 910 is connected to the upper end of the second unloading plate 920, and the lower end of the first unloading plate 910 is opposite to the lower end of the second unloading plate 920. The whole formed by the first unloading plate 910 and the second unloading plate 920 is inverted "V" shape.

[0039] See Figure 6 In some embodiments of this utility model, in order to avoid the discharged products from colliding with the rack 100 and to ensure that the products can be discharged smoothly and received by the container placed on the ground, both the front end plate 930 and the rear end plate 940 are inclined from top to bottom and forward.

[0040] See Figure 3 and Figure 4In some embodiments of this utility model, the lower edges of the front and rear side plates of the hopper 300 are both "V" shaped. The front and rear sides of the first door plate 320 and the second door plate 330 are respectively provided with curved plate portions that are rotatably connected to the front and rear side plates of the hopper 300. A tension spring 340 is provided between the curved plate portion on the front side and the hopper 300 to drive the first door plate 320 and the second door plate 330 to close. The curved plate portion on the rear side is rotatably connected to a connecting arm 350. The end of the connecting arm 350 is rotatably connected to a rotating arm 360. The rotating arm 360 is provided with a drive plate 361 that drives it to rotate. The second drive mechanism 600 includes a second motor 610 and a second crank 620 connected to the output shaft of the second motor 610. The second crank 620 is located between the two drive plates 361. The second crank 620 rotates clockwise or counterclockwise to drive one of the first door plate 320 and the second door plate 330 to rotate. Understandably, with Figure 3 In an example embodiment, when a product enters the left-side hopper 300, if the weighing module 400 detects that the weight of the product meets the set range, the second motor 610 drives the second crank 620 to rotate. The second crank 620 then rotates the rotating arm 360 corresponding to the second door panel 330. Through the connecting arm 350, the second door panel 330 is opened, and the product can fall along the first door panel 320 towards the first discharge channel.

[0041] See Figure 5 In some embodiments of this utility model, the hopper 300 is connected to the sensor of the weighing module 400 via a connecting frame 370, so that the hopper 300 presses downward against the sensor of the weighing module 400. The frame 100 is provided with a limiting member 410 to restrict the upward displacement of the hopper 300. When the product falls into the hopper 300, the hopper 300 and the product together press downward against the sensor of the weighing module 400 to obtain weight data, thereby obtaining the specific weight data of the product. The limiting member 410 can prevent damage to the sensor of the weighing module 400 when the hopper 300 is lifted upward by external force.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
