Description

Technical Field

[0001] The utility model relates to the field of weighing, in particular to an anti-collision weighing conveyor. Background Art

[0002] A weighing conveyor generally includes a horizontal conveyor, several weighing sensors and a support frame. The horizontal conveyor is installed on the support frame through the weighing sensor. After the material enters the horizontal conveyor, the weighing sensor weighs the material on the horizontal conveyor. The weighing result minus the weight of the horizontal conveyor is the material weight.

[0003] However, materials are generally transferred to the horizontal conveyor through other equipment. There is no doubt that the horizontal conveyor may be hit during this process. If the horizontal conveyor is hit, it may cause damage to the horizontal conveyor and may also cause damage to the connection structure between the weighing sensor and the horizontal conveyor or the support frame, thereby affecting the normal operation of the weighing conveyor.

[0004] At present, there is a circle or half circle of guardrails around the area where the weighing conveyor is located, and the weighing conveyor is located within the range of the guardrail. Although this situation can protect the weighing conveyor, the guardrail will cause inconvenience in the process of transferring materials to the horizontal conveyor, and it occupies a large area. Once the weighing conveyor is moved, the guardrail needs to be removed and moved to another position, resulting in poor flexibility in use. Summary of the invention

[0005] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide an anti-collision weighing conveyor, which can effectively prevent the weighing conveyor from being damaged by collision and has high flexibility in use.

[0006] In order to solve the above technical problems, the technical solution of the utility model is: an anti-collision weighing conveyor, including a support frame, a horizontal conveyor and a plurality of weighing sensors, the weighing sensors are installed on the support frame, the horizontal conveyor is installed at the weighing end of the weighing sensors, and the support frame is provided with an anti-collision frame surrounding the side of the horizontal conveyor with a gap.

[0007] A specific structure of an anti-collision frame is further provided, and the anti-collision frame includes a front anti-collision portion, a left anti-collision portion and a right anti-collision portion located at the front side, left side and right side of the horizontal conveyor.

[0008] In order to further reduce the probability of the front bumper frame being hit, the front bumper portion is tilted backward from top to bottom.

[0009] A more rational structure is further provided, wherein the upper ends of the left anti-collision part and the right anti-collision part are not lower than the horizontal conveyor, and the upper end of the front anti-collision part is not higher than the horizontal conveyor.

[0010] Furthermore, there are four weighing sensors, which respectively support the left front, right front, left rear and right rear of the horizontal conveyor.

[0011] In order to further play a role of shock absorption and buffering and prevent the weighing sensor from being damaged due to sudden force, a shock absorber is arranged between the horizontal conveyor and each weighing sensor.

[0012] Furthermore, the weighing sensor is a cantilever weighing sensor, the fixed end of the cantilever weighing sensor is fixedly mounted on the support frame, the lower end of the shock absorber is connected to the swing arm end of the cantilever weighing sensor, and the upper end is connected to the horizontal conveyor.

[0013] After adopting the above technical solution, after setting up the anti-collision frame, even if the external force hits the entire weighing conveyor, it is borne by the anti-collision frame. The horizontal conveyor and the weighing sensor are protected by the anti-collision frame. On the one hand, the horizontal conveyor and the weighing sensor can be prevented from being damaged. On the other hand, the connection between the horizontal conveyor and the weighing sensor or the connection between the weighing sensor and the support frame can be prevented from being affected due to the impact of the horizontal conveyor, thereby ensuring the weighing accuracy. In addition, compared with the form of setting up a guardrail in the area where the weighing conveyor is located, this anti-collision weighing conveyor hardly increases the floor space and has higher flexibility in use.

[0018] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0019] like Figure 1 , 2As shown in Figure 3, an anti-collision weighing conveyor includes a support frame 1, a horizontal conveyor 2 and a plurality of weighing sensors 3. The weighing sensors 3 are installed on the support frame 1, the horizontal conveyor 2 is installed at the weighing end of the weighing sensors 3, and the support frame 1 is provided with an anti-collision frame 4 surrounding the side of the horizontal conveyor 2 with a gap.

[0020] It should be noted that the anti-collision frame 4 is a part of the support frame 1, and the anti-collision frame 4 is connected to the support frame 1 as an integral structure. The horizontal conveyor 2 is a conventional structure, including a conveyor frame, a driving pulley and a driven pulley respectively rotatably supported on the conveyor frame, a conveyor belt tensioned on the driving pulley and the driven pulley, and a power mechanism, the power mechanism is fixedly installed on the conveyor frame and connected to the driving pulley to drive the driving pulley to rotate. The conveyor frame of the horizontal conveyor 2 is installed at the weighing end of the weighing sensor 3.

[0021] Specifically, after the anti-collision frame 4 is set, even if the external force hits the entire weighing conveyor, it is borne by the anti-collision frame 4. The anti-collision frame 4 protects the horizontal conveyor 2 and the weighing sensor 3. On the one hand, it can prevent the horizontal conveyor 2 and the weighing sensor 3 from being damaged. On the other hand, it can prevent the connection between the horizontal conveyor and the weighing sensor 3 or the connection between the weighing sensor and the support frame 1 from being affected due to the impact of the horizontal conveyor 2, thereby ensuring the weighing accuracy. In addition, this anti-collision weighing conveyor is more flexible in use than setting a guardrail in the area where the weighing conveyor is located.

[0022] The number of the weighing sensors 3 may be 2, 3, 4, 5, etc. In the present embodiment, there are four weighing sensors 3, which respectively support the left front, right front, left rear and right rear of the horizontal conveyor 2.

[0023] In one embodiment, Figure 1 As shown, the anti-collision frame 4 includes a front anti-collision portion 41 , a left anti-collision portion 42 and a right anti-collision portion 43 located at the front side, left side and right side of the horizontal conveyor 2 .

[0024] Specifically, materials enter the horizontal conveyor 2 from the front and / or left side and / or right side of the horizontal conveyor, and the front, left and right sides of the horizontal conveyor 2 are more likely to be hit. Therefore, only the front anti-collision part 41, the left anti-collision part 42 and the right anti-collision part 43 are provided. While being able to effectively prevent collisions, the material and cost of the support frame 1 can be reduced.

[0025] In one embodiment, Figure 1 As shown, the front bumper 41 is inclined from top to bottom and rearward.

[0026] Specifically, the possibility of materials entering the horizontal conveyor 2 from the front side is generally higher. The front anti-collision part 41 is configured in this way, so that even if the equipment that transfers the materials is closer to the front side of the horizontal conveyor 2, it can avoid hitting the front anti-collision part 41 as much as possible.

[0027] In one embodiment, Figure 1 As shown, the upper ends of the left anti-collision part 42 and the right anti-collision part 43 are not lower than the horizontal conveyor 2, and the upper end of the front anti-collision part 41 is not higher than the horizontal conveyor 2.

[0028] In this way, it can be ensured that the front anti-collision part 41 will not interfere with the process of materials entering the horizontal conveyor 2, and it can also be ensured that the protection effect of the left anti-collision part 42 and the right anti-collision part 43 is better.

[0029] In one embodiment, Figure 3 As shown, a shock absorber 5 is arranged between the horizontal conveyor 2 and each weighing sensor 3 .

[0030] In this way, it can play the role of shock absorption and buffering, preventing the weighing sensor from being damaged due to sudden force.

[0031] In one embodiment, Figure 3 As shown, the weighing sensor 3 is a cantilever weighing sensor 3 , the fixed end of the cantilever weighing sensor is fixedly mounted on the support frame 1 , the lower end of the shock absorber 5 is connected to the swing arm end of the cantilever weighing sensor 3 , and the upper end is connected to the horizontal conveyor 2 .

[0032] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
