Description

Technical Field

[0001] The utility model relates to the technical field of material transportation, in particular to a limiting mechanism for materials on a conveyor belt. Background Art

[0002] At present, in the production process of edible oil, the first thing to do is to fill it. After filling, the product needs to be boxed. The boxed products are transported to the palletizer by a roller conveyor, and then the palletizer is used to stack the products on the pallet, so as to facilitate the subsequent transfer.

[0003] Existing roller conveyors lack the ability to limit product position during product transport, which can easily lead to multiple products piling up at the palletizer's grabbing area, affecting the ability to grab each product individually. Furthermore, the lack of a position limiter during product transport on roller conveyors affects the accuracy of the conveying position and hinders accurate palletizing. Therefore, we propose a position limiter for materials on conveyor belts. Utility Model Content

[0004] The purpose of the utility model is to provide a limiting mechanism for materials on a conveyor belt, which solves the problems raised in the background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a limiting mechanism for materials on a conveyor belt, comprising a roller conveyor, wherein guide assemblies are provided on both sides of the top of the roller conveyor, and the bottom of the roller conveyor is fixedly connected to the limiting assembly;

[0006] The limiting assembly includes a base plate, both sides of the top of the base plate are fixedly connected to the roller conveyor through a connecting plate, an electric push rod is fixed at the middle of the top of the base plate, the outer end of the electric push rod is fixedly connected to a shell, an adaptive movable plate is inserted into the top open inner cavity of the shell, springs are fixed on both sides of the bottom of the movable plate, the bottom of the spring is fixedly connected to the bottom of the inner cavity of the shell, the movable plate passes through between the two roller shafts on the roller conveyor, and a controller is fixed to the side wall of the roller conveyor.

[0007] When the product box is moved to the end of the roller conveyor, the palletizer will grab it, and after the grabbing is completed, the control end of the palletizer will feedback a signal to the controller, and the controller will start the electric push rod to repeat the above operation, so that the next product box can be released again, thereby releasing the products one by one, ensuring that the palletizer can avoid product accumulation at the grabbing point when grabbing the products.

[0008] As a preferred embodiment of the present invention, the guide assembly includes a guide plate and an end plate, and the number of the end plates is multiple, and the multiple end plates are evenly fixed on the top of the side of the roller conveyor. The guide plate is arranged on the upper side of the roller conveyor, and the outer wall of the end plate is threaded with an adjusting bolt, and the end of the adjusting bolt is rotatably connected to the guide plate.

[0009] By adopting the above technical solution, rotating the adjustment bolt can drive the guide plate to adjust its position, and the guide plates on both sides can be used to limit and guide the product, ensuring that the product is accurately positioned when transported to the palletizer's grasping point, which is conducive to improving the accuracy of grasping.

[0010] As a preferred embodiment of the present invention, a plurality of evenly distributed balls are embedded on the top of the movable plate.

[0011] By adopting the above technical solution, the setting of the ball enables the movable plate to contact the bottom of the product box so that the ball can be attached to the bottom of the product box, thereby rolling the ball and avoiding the movable plate from causing wear on the bottom of the box.

[0012] As a preferred embodiment of the present invention, fixed plates are attached to both sides of the two side walls of the shell, the tail end of the fixed plate is fixedly connected to the top of the bottom plate, the outer wall of the fixed plate is provided with a strip hole, and an adaptive sliding block is slidably arranged in the strip hole, and the sliding block is fixedly connected to the outer wall of the shell.

[0013] By adopting the above technical solution, when the electric push rod drives the shell to rise and fall, the sliding block can be used to limit the sliding in the strip hole, thereby ensuring high stability of the shell rising and falling.

[0014] As a preferred embodiment of the present invention, a limit plate is fixed at one end of the roller conveyor.

[0015] By adopting the above technical solution and setting the limiting plate, it is possible to limit the position of the product box that has been delivered to the right position, thereby facilitating further grabbing by the palletizer.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] The technical solution of the present application is a limiting mechanism for materials on a conveyor belt. The limiting component can limit the position of other products on the roller conveyor when the palletizer grabs the goods, and can release the products one by one after a single grab is completed, thereby preventing the accumulation of products at the palletizing area, which is beneficial to prevent the grabbing from being affected by the accumulation of products.

[0018] Guide plates are installed on both sides of the roller conveyor. By rotating the adjusting bolts, the guide plates can be adjusted to adjust their positions, thereby limiting the product and accurately guiding the product, ensuring that the product is accurately positioned when it is transported to the palletizer's grasping point, which is conducive to improving the accuracy of grasping.

[0028] See also Figure 1-4 The utility model provides a technical solution: a limiting mechanism for materials on a conveyor belt, comprising a roller conveyor 1, guide assemblies are provided on both sides of the top of the roller conveyor 1, and a limiting assembly 3 is fixedly connected to the bottom of the roller conveyor 1;

[0029] The limiting assembly 3 includes a base plate 31, both sides of the top of the base plate 31 are fixedly connected to the roller conveyor 1 through connecting plates 32, an electric push rod 35 is fixed at the middle of the top of the base plate 31, the outer end of the electric push rod 35 is fixedly connected to the shell 33, and the top open inner cavity of the shell 33 is plugged with an adaptive movable plate 34, and springs 39 are fixed on both sides of the bottom of the movable plate 34, the bottom of the spring 39 is fixedly connected to the bottom of the inner cavity of the shell 33, the movable plate 34 runs through between the two roller shafts on the roller conveyor 1, and the side wall of the roller conveyor 1 is fixed with a controller 12.

[0030] It should be noted that the controller 12 is connected to the control end of the palletizer, and the signal output end of the controller 12 is connected to the signal input end of the electric push rod 35;

[0031] When the product is transported to the end of the roller conveyor 1, the palletizer will grab it, and after the grabbing is completed, the control end of the palletizer will feedback a signal to the controller 12, and the controller 12 will start the electric push rod 35 to repeat the above operation, so that the next product box can be released again, thereby releasing the products one by one, ensuring that the palletizer can avoid the accumulation of products at the grabbing point when grabbing the products.

[0032] Furthermore, a plurality of evenly distributed balls 36 are embedded on the top of the movable plate 34. The arrangement of the balls 36 enables the movable plate 34 to be in contact with the bottom of the product box when the movable plate 34 is against the bottom of the product box, so that the balls 36 roll, thereby preventing the movable plate 34 from causing wear on the bottom of the box.

[0033] Furthermore, both sides of the housing 33 are fitted with fixing plates 37, the tail end of the fixing plates 37 is fixedly connected to the top of the bottom plate 31, and the outer wall of the fixing plates 37 is provided with a strip hole, in which an adapted sliding block 38 is slidably provided, and the sliding block 38 is fixedly connected to the outer wall of the housing 33;

[0034] Therefore, when the electric push rod 35 drives the housing 33 to move up and down, the sliding block 38 can be used to slide within the strip hole to ensure high stability in the lifting of the housing 33.

[0035] It is worth mentioning that a limit plate 11 is fixed at one end of the roller conveyor 1. The setting of the limit plate 11 enables the product boxes conveyed into position to be limited, thereby facilitating further grabbing by the palletizer.

[0036] like Figure 1 As shown; the guide assembly includes a guide plate 2 and an end plate 21, the number of the end plates 21 is multiple, and the multiple end plates 21 are evenly fixed to the top of the side of the roller conveyor 1. The guide plate 2 is arranged on the upper side of the roller conveyor 1. The outer wall of the end plate 21 is threaded with an adjusting bolt 22, and the end of the adjusting bolt 22 is rotatably connected to the guide plate 2;

[0037] By rotating the adjusting bolt 22, the guide plate 2 can be driven to adjust its position, and the guide plates 2 on both sides can be used to limit and guide the product, ensuring that the product is accurately positioned when transported to the palletizer grabbing location, thereby improving the accuracy of grabbing.

[0038] The implementation principle of the limiting mechanism for materials on the conveyor belt of the present application is as follows: first, rotating the adjusting bolt 22 can drive the guide plate 2 to adjust the position, and using the guide plates 2 on both sides to achieve limiting and guiding of the product, and then the electric push rod 35 drives the shell 33 and the movable plate 34 to lift, so that the movable plate 34 extends, so that the product can be limited when it is conveyed along the roller conveyor 1, and then the electric push rod 35 is started to drive the shell 33 and the movable plate 34 to descend, so that the limited product is released, and when released, the shell 33 and the movable plate 34 are lifted again, so that the movable plate 34 rests on the bottom of the product box. The spring 39 is compressed. When a single product box is conveyed beyond the limit assembly 3, the reverse thrust of the spring 39 causes the movable plate 34 to rise so that the next product box can be limited again. Then, the released product box moves to the end of the roller conveyor 1, and the palletizer grabs it. At the same time, after the grabbing is completed, the control end of the palletizer will feedback a signal to the controller 12, and the controller 12 will start the electric push rod 35 to repeat the above operation, so that the next product box can be released again, thereby achieving the release of products one by one, ensuring that the palletizer can avoid the accumulation of products at the grabbing point when grabbing products.

[0039] In addition, the components included in the limiting mechanism for materials on a conveyor belt of the utility model are all universal standard parts or components known to technical personnel in this field. The structure and principle thereof can be known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and adapted monitoring computers and power supplies, are connected through wires.
