[0001] The utility model belongs to the field of checkweighers, and in particular relates to a checkweigher conveyor belt with a level adjustment function. Background Art

[0002] During the processing of the product production line, the finished product needs to be weighed. The existing technology has a conveyor belt checkweigher, which combines product transmission and automatic weighing. The checkweigher generally has a front conveyor belt and a rear conveyor belt, which are respectively used to connect with other transmission devices in the production line (such as the previous level transmission device and the next level transmission device).

[0003] For checkweighers, the front and rear conveyor belts sometimes need to be adjusted horizontally as needed to adjust the required spacing to prevent contact during the distance process and affect weighing. However, the spacing between the driven roller and the driving roller of the existing checkweigher conveyor belt is fixed. During the horizontal adjustment process, it is easy for the spacing at one end to be appropriate while the spacing at the other end is inappropriate. Utility Model Content

Specific embodiments

[0021] The following further describes the present application in detail with reference to the accompanying drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and cannot be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0022] Embodiment 1

[0023] As Figures 1-4 shown, a weight-checking scale conveyor belt with a horizontal adjustment function includes a conveyor belt frame 1. A driving roller 13 and a driven roller 11 are provided on the conveyor belt frame 1. A horizontal adjustment mechanism 2 is arranged on the conveyor belt frame 1. The shaft end of the driven roller 11 is slidably connected to the conveyor belt frame 1 through a sliding part 12 for adjusting the distance between the driving roller 13 and the driven roller 11 during horizontal adjustment. And the sliding part 12 is connected to the conveyor belt frame 1 and / or other transmission devices through fixing parts. A tensioning mechanism 3 is also arranged inside the conveyor belt frame 1.

[0024] In this solution, by setting the slidable driven roller 11, it can be fixed to the conveyor belt frame 1 or to other transmission devices. During the horizontal adjustment of the conveyor belt frame 1, the distance between the driven roller 11 and the driving roller 13 can be changed accordingly to adapt to the current distance. After the adjustment is completed, the conveyor belt is tensioned downward from the middle section of the conveyor belt through the tensioning mechanism 3, effectively improving the adaptability and compatibility of the weight-checking scale conveyor belt with other transmission devices on the production line during the horizontal adjustment process.

[0025] The horizontal adjustment mechanism 2 includes a fixed seat 21 for connecting with an external structure. A convex block 22 extends from the side surface of the fixed seat 21. The convex block 22 is slidably connected to an adjustment groove 14 formed on the conveyor belt frame 1. A fixing bolt 23 is further provided on the surface of the conveyor belt frame 1, which presses and fixes the conveyor belt frame 1 on the fixed seat 21 through a threaded structure. This solution specifically proposes a horizontal adjustment method, which is supported by the convex block 22 and the fixing bolt 23 passes through the conveyor belt frame 1 and is threadedly connected to the fixed seat 21 for easy pressing and fixing. The position where the fixing bolt 23 passes through the conveyor belt frame 1 has a slotted head, and a rotating handle can be further provided to facilitate the manual rotation of the fixing bolt 23.

[0026] The fixed seat 21 is located inside the conveyor belt frame 1, and the fixed seat 21 is fixed to the external structure through the installation rod 5 passing through and connected. Utilizing the internal space of the conveyor belt frame 1, further, the installation rod 5 can be connected and fixed to the external structure through the mounting plate 4.

[0027] The tensioning mechanism 3 includes a tensioning roller 31. The tensioning roller 31 is located between the driven roller 11 and the driving roller 13, and it presses down on the conveyor belt to tension the conveyor belt. By setting the tensioning roller 31, it presses down from the middle part of the conveyor belt to achieve the purpose of tensioning without affecting the span of the driven roller 11 and the driving roller 13. A lifting part 32 is provided at the shaft end of the tensioning roller 31, and the lifting part 32 is driven by a threaded rod 34 through a threaded structure. By setting the threaded structure to drive the lifting part 32 to move up and down to control the up and down movement of the tensioning roller 31. An auxiliary member 33 for restricting the movement track of the lifting part 32 is provided inside the conveyor belt frame 1.

[0028] The two threaded rods 34 extend downward and are provided with worm gears 36. A worm 37 that simultaneously meshes with the two worm gears 36 is disposed through the conveyor belt frames 1. By rotating the worm 37, the two threaded rods 34 can be simultaneously driven to rotate, and the structure of the worm gear 36 and the worm 37 also has a self-locking effect. In order to prevent the axial movement of the worm 36, a limiting member can be provided on the worm 36. A card slot 16 is provided on the side surface of the conveyor belt frame 1. The card slot 16 is formed by connecting two circular grooves. The worm 37 passes through one of the circular grooves and meshes with the worm gear 36, and is snapped into the other circular groove to disengage from the worm gear 36. An elastic component 35 is further provided at the end of the threaded rod 34. The elastic component 35 has the potential energy to drive the threaded rod 34 to drive the lifting part 32 to rise. When it is necessary to completely release the tensioning mechanism, by disengaging the worm from the worm gear, the tensioning roller rises under the drive of the elastic component, so as to quickly release the tensioning effect.

[0029] The specific implementation method is as follows: when the conveyor belt frame 1 is horizontally adjusted, there are two situations. In one situation, the distance between the driven roller 11 and the previous stage transmission device cannot be changed, so the sliding part 12 is fixedly connected to the previous stage transmission device. Before the horizontal adjustment, the worm 37 is first toggled to switch in the card slot 16 so that the worm 37 is disengaged from the worm gear 36. Driven by the elastic component 35, the threaded rod 34 rotates to make the tensioning roller 31 rise. At this time, the conveyor belt is in a relaxed state, and the sliding part 12 is connected to the previous stage transmission device. When the conveyor belt frame 1 is horizontally adjusted, the span can be adaptively adjusted. After the adjustment is completed, the worm 37 is returned to engage with the worm gear 36, and the worm 37 is rotated to rotate the threaded rod 34, driving the tensioning roller 31 to descend and tighten the conveyor belt; in the other situation, the distance between the driven roller 11 and the previous stage transmission device can be changed, and there is no need to change the span between the driving roller 13 and the driven roller 11. The sliding part 12 is fixed to the conveyor belt frame 1, and then the conveyor belt frame 1 can be horizontally adjusted.

[0030] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
