[0025] like Figures 1 to 4As shown, the present embodiment provides a knife-edge belt climbing weighing machine, including a frame 1, a climbing conveyor 2, an inlet section conveyor 3, a weighing section conveyor 4, a rejecting section conveyor 5 and a downhill conveyor 6. The inlet section conveyor 3, the weighing section conveyor 4 and the rejecting section conveyor 5 are fixed on the frame 1 and arranged in sequence. The climbing conveyor 2 is located at the front side of the inlet section conveyor 3. In order to allow the conveyed objects to move up, the climbing conveyor 2 enters the inlet section conveyor 3. The downhill conveyor 6 is located at the rear side of the rejecting section conveyor 5. After the weighed objects are weighed on the weighing section conveyor 4, if it is monitored that the weighed objects are higher or lower than a threshold value, an alarm or a reminder is issued, and the weight is supplemented or reduced on the rejecting section conveyor 5 to reach the required qualified products. The climbing conveyor 2, the inlet section conveyor 3, the weighing section conveyor 4, the rejecting section conveyor 5 and the downhill conveyor A conveying mechanism 7 is respectively provided on the slope conveyor 6, wherein the conveying mechanism 7 on the climbing conveyor 2 and the downhill conveyor 6 forms an acute angle A with the horizontal plane, and the acute angle A is 20°-30°. The frame 1 includes an upper frame 11, a lower frame 12 and a support frame 13, the upper part of the support frame 13 is fixedly connected to the side of the upper frame 11, and the side position of the lower frame 12 is fixedly connected to the bottom of the support frame 13, and a through passage is formed between the upper frame 11 and the lower frame 12. By moving the knife-edge belt climbing weighing machine to the existing conveyor line, a conveyor line channel is left between the upper frame 11 and the lower frame 12, and the climbing conveyor 2 and the downhill conveyor 6 are attached to the conveyor line, so that the weighing machine can be used without modifying the existing conveyor line, without affecting the normal operation of the production line, with low cost and greater flexibility.

[0026] Furthermore, the climbing conveyor 2, the inlet section conveyor 3, the weighing section conveyor 4, the rejection section conveyor 5 and the downhill conveyor 6 are each provided with a motor 71, and the motor 71 drives the conveying mechanism 7 to rotate. The motor 71 is provided with a driving gear 72, and the conveying mechanism 7 is provided with a driven gear 73, and a synchronous belt 74 is provided between the driving gear 72 and the driven gear 73.

[0027] Furthermore, the weighing section conveyor 4 includes a weighing device 41 and a first conveying bracket 42, the weighing device 41 is fixed on the upper frame 11, the first conveying bracket 42 is fixed on the weighing device 41, the conveying mechanism 7 is installed on the first conveying bracket 42, the conveying mechanism 7 and the first conveying bracket 42 are both set on the weighing device 41 and reset, and then when the weighed object passes through the conveying mechanism 7, the weight of the object will be actually detected to determine whether the weight reaches the preset threshold.

[0028] Furthermore, the conveying mechanism 7 includes a front roller 75, a rear roller 76, a conveying plate 77 and a conveying belt 78, the front roller 75 and the rear roller 76 are located in front and rear positions of the conveying plate 77, the conveying belt 78 wraps the front roller 75, the rear roller 76 and the conveying plate 77, and the driven gear 73 is installed at the end position of the rear roller 76.

[0029] Furthermore, the diameter of the front roller 75 of the climbing conveyor 2 and the downhill conveyor 6 is smaller than the diameter of the rear roller 76, so that small-sized items can be lifted from the conveyor belt 78 of the front roller 75 for transportation.

[0030] Furthermore, raised columns 79 are provided on both sides of the conveying mechanism 7, and lock buckles 8 are provided on the climbing conveyor 2 and / or the inlet section conveyor 3 and / or the weighing section conveyor 4 and / or the rejection section conveyor 5 and / or the downhill conveyor 6, and the lock buckles 8 lock the raised columns 79. In order to facilitate the disassembly of the conveying mechanism 7, this structure requires first separating the synchronous belt 74, and then opening the lock buckle 8. When the raised column 79 is not constrained by the lock buckle 8, the conveying mechanism 7 can be lifted up for easy cleaning.

[0031] like Figure 5 As shown, the conveying plate 77 includes a front plate 771 and a rear plate 772, the front roller 75 is located at the front end of the front plate 771, and the rear roller 76 is located at the rear end of the rear plate 772.

During the rotation, the conveyor belt 78 can be disassembled. This method is convenient, simple and fast.

[0032] like Figure 6 As shown, the front end of the front plate 771 is provided with a slot 777, and the front roller 75 is arranged in the slot 777. One end of the slot 777 is provided with an adjusting screw 776 for supporting the front roller 75. When the conveyor belt 78 becomes loose, it can be tightened to increase the friction.

[0034] In the prior art, when weight re-inspection is required, the existing production line can only be disassembled and modified to add weight detection equipment, which will affect the normal operation of the production line. Different processes have different requirements, and the position of the weight detection equipment has also changed. Modifying the production line will incur a large cost. Therefore, a knife-edge belt climbing weighing machine is used. A channel for the conveyor line can be left on the frame 1. As long as it is moved to the existing production line, there are climbing conveyors 2, inlet conveyors 3, weighing conveyors 4, rejection conveyors 5 and downhill conveyors 6 on the frame 1. The climbing conveyors 2 and downhill conveyors 6 can be fitted on the production line to change the direction of transportation, and the weighed objects can be moved to the climbing conveyor 2 for weighing. When the material is transported from the external supporting equipment to the knife-edge climbing conveyor 1, the climbing conveyor 1 transports the material to the inlet conveyor 2 to achieve material separation and adjustment, and then enters the weighing conveyor 4 separately to achieve the weighing and metering function; the rejection conveyor 5 can be equipped with a lateral rejection device to reject and separate unqualified products. The unqualified products can also be manually supplemented with materials or reduced in weight to reach the qualified level before entering the knife-edge downhill conveyor 6; the qualified weight is achieved and displayed on the touch screen of the electric control box or the detailed product records are made.

[0035] The knife-edge type belt climbing weighing machine weighs and measures the materials through the weighing section conveyor 4 and performs real-time weighing through the sensor and weight display control through the electric control box; when the weight reaches the qualified standard, the section conveyor 5 is rejected; the knife-edge type downhill conveyor 6 will send the materials to the qualified area; when it is detected that the weight deviates from the qualified standard range, the rejecting section conveyor 5 will send the materials to the unqualified area under the action of the configured rejection device, thereby realizing the distinction and grading of qualified and unqualified weights.

[0036] The use of this knife-edge belt climbing weighing machine can better work in water environment and improve product quality. In the direct import food packaging industry, direct human contact is not suitable, and even the emergence of sterile environment requirements requires more suitable machines to adapt to this kind of work; due to the continuous working requirements of packaging and the need to reduce human intervention, the demand for knife-edge belt climbing weighing machines is becoming increasingly tight.

[0037] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited thereto. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention are all equivalent replacement methods and are included in the protection scope of the present invention.
