If the first and second are described, it is only for the purpose of distinguishing technical features and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0029] In the description of the present application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present application in combination with the specific content of the technical solution.

[0030] The belt weigher weighs the material above at a certain frequency, and the weight of a single material can be calculated based on the total weight and the frequency of the material fed into the belt weigher. If the intervals of the materials are inconsistent, it will cause a large fluctuation in the feeding frequency and affect the weighing accuracy.

[0031] In some related technologies, the speed of the conveyor belt upstream of the belt weigher can be adjusted in real time according to the spacing of the materials, so as to make the materials fed evenly. However, when the speed changes, it is easy to cause the materials (especially slender materials with light weight such as portable gas cylinders) to fall over.

[0032] In some other related technologies, baffles are used to block the materials. The baffles are opened at a set frequency, so that the intervals of the materials become consistent, and the baffles are not easy to cause the materials to fall over. However, the materials blocked by the baffles will collide with each other, easily causing damage to the surface and affecting the appearance quality of the materials.

[0033] Refer to Figure 1 , according to the material conveying device provided by the embodiment of the present application, including a conveying component 100 and an adjusting component. The conveying component 100 is used to carry and convey the material 900 along the first direction. The adjusting component is located above the conveying component 100. The adjusting component includes a second conveyor belt 210. The two second conveyor belts 210 are symmetrically arranged at intervals in the second direction to form an adjusting channel extending in the first direction. The adjusting channel is used to clamp and convey the material 900. The adjusting component can change the linear speed of the second conveyor belt 210 located in the adjusting channel to adjust the interval of the conveyed material 900.

[0034] The material conveying device is used to convey the material 900 downstream (for example, to the belt weigher). During the conveying process, the material 900 passes through the adjusting channel and is thus clamped and conveyed by the two second conveyor belts 210. In Figure 1 the illustrated embodiment, the first direction is the front-back direction and the second direction is the left-right direction.

[0035] On the one hand, by changing the linear speed of the second conveyor belt 210 that clamps the material, the timing of the material 900 leaving the adjustment channel can be adjusted, so that the intervals between the materials 900 are more uniform, and thus the material conveying device can improve the uniformity of the material 900 conveying.

[0036] On the other hand, since the material 900 is stably clamped by the second conveyor belt 210 during the adjustment process, it is not easy to overturn when the speed changes.

[0037] Finally, the total length of the second conveyor belt 210 in the adjustment assembly will obviously be smaller than the conveying structure used by the conveyor assembly 100 (in Figure 1 In the embodiment shown, the total length of the first conveyor belt is shown, so the weight and inertia of the second conveyor belt 210 are also reduced accordingly, which helps to eliminate the hysteresis of the adjustment and makes the adjustment of the linear speed more sensitive.

[0038] The present application further provides material weighing equipment, which includes a belt weighing machine and a material conveying device provided in the present application.

[0039] The material weighing equipment also has the beneficial effects provided by the physical conveying device, which will not be described in detail here.

[0040] It is understandable that in Figure 1 In the illustrated embodiment, the conveyor assembly 100 includes a first conveyor belt, a first driving wheel, and a first driven wheel. The first conveyor belt is wound around the first driving wheel and the first driven wheel to achieve a conveying function. In other embodiments, the conveyor assembly 100 may also use a chain plate or other structure to achieve conveying, and this application is not limited to this. The conveyor assembly 100 also includes a first drive member for driving the first driving wheel.

[0041] In addition to the second conveyor belt 210, the adjustment assembly obviously also includes a second driving wheel 220 and a second driven wheel 230. The second driving wheel 220 and the second driven wheel 230 are arranged at intervals along the first direction, and the second conveyor belt 210 is wound around the second driving wheel 220 and the second driven wheel 230. The adjustment assembly also includes a second driving member 240 for driving the second driving wheel 220.

[0042] It should be pointed out that the adjustment component can change the linear speed of the second conveyor belt 210 in a variety of ways. For example, in some embodiments, the adjustment component can change the rotational speed of the second driving wheel 220 in real time according to the interval of the material 900, but this method has higher performance requirements for the second driving member 240.

[0043] To this end, optionally, in some embodiments, the adjustment component includes a tension buffer 250, the second driving wheel 220 is located upstream of the second driven wheel 230, the tension buffer 250 is capable of caching or releasing the second conveyor belt 210 located outside the adjustment channel, and the second driving wheel 220 is capable of floating in the first direction in response to the tension buffer 250 to adjust the moving speed of the material 900.

[0044] Specifically, refer to Figure 1 The second conveyor belt 210 can be divided into a part located within the adjustment channel and a part located outside the adjustment channel. The linear speed of the second conveyor belt 210 located within the adjustment channel is determined by the rotation speed of the second driving wheel 220 and the moving speed of the second driving wheel 220 in the first direction. When the tension buffer 250 releases a part of the second conveyor belt 210, the floating second driving wheel 220 moves away from the second driven wheel 230, thereby reducing the linear speed of the second conveyor belt 210 located within the adjustment channel. On the contrary, when the tension buffer 250 caches a part of the second conveyor belt 210, the second driving wheel 220 approaches the second driven wheel 230, thereby increasing the linear speed of the second conveyor belt 210 located within the adjustment channel.

[0045] Therefore, by introducing the tension buffer member 250 that can actively move, the effect of adjusting the conveying interval of the material 900 is achieved. At this time, the second driving wheel 220 can run at a uniform speed, and the burden on the second driving member 240 is also reduced.

[0046] At this time, optionally, the linear speed of the first conveyor belt and the linear speed of the second driving wheel 220 can be set to be the same, and both are equal to the linear speed of the downstream equipment (such as a belt weighing machine), so that ideally no buffering or release is required.

[0047] Optionally, in some embodiments, the tension buffering member 250 includes a rotating wheel located on a side of the second conveyor belt 210 away from the adjustment channel. The adjustment assembly includes a third driving member 260. The third driving member 260 can drive the rotating wheel toward or away from the second conveyor belt 210 to buffer or release the second conveyor belt 210. Since the rotating wheel can rotate, the frictional resistance between the rotating wheel and the second conveyor belt 210 is reduced, making transportation smoother.

[0048] For example, the wheel can be moved closer to or farther away from the second conveyor belt 210 by rotating. Figure 2 In some embodiments, the rotating wheel is an eccentric wheel, and the third driving member 260 is connected to the eccentric shaft of the eccentric wheel. The third driving member 260 can drive the eccentric wheel to rotate around the eccentric shaft.

[0049] Of course, the above only illustrates an easier-to-understand cache implementation method. In other embodiments, the second driving wheel 220 may also be located downstream, and the tension buffer element 250 may also be composed of multiple wheels, and the wheels may also move closer to or away from the second conveyor belt 210. This application does not impose any restrictions on this.

[0050] Reference Figure 2 and Figure 3 In order to achieve a floating effect, in some embodiments, the adjustment component further includes a fixed platform 270 and a floating seat 280. The floating seat 280 is movably arranged on the fixed platform 270. The second driving member 240 is installed on the floating seat 280. The second driving member 240 is connected to the second driving wheel 220 in a transmission manner.

[0051] Furthermore, in some embodiments, the adjustment assembly further includes a guide shaft 290 extending in the first direction. The guide shaft 290 is connected between the fixed platform 270 and the floating seat 280 to guide the floating seat 280 .

[0052] The guide shaft 290 makes the displacement of the floating seat 280 more accurate, thereby preventing the second driving wheel 220 from deviating in the second direction and affecting the clamping effect on the material 900 .

[0053] In order to ensure that the second driving wheel 220 can move away from the second driven wheel 230 in time when the tension buffer 250 releases the second conveyor belt 210, thereby tensioning the second conveyor belt 210 to avoid problems such as slipping and tooth jumping, in some embodiments, the adjustment component includes an elastic member, which abuts the floating seat 280 to drive the floating seat 280 to reset.

[0054] The elastic member may be a compression spring, for example, referring to Figure 2 and Figure 3 The guide shaft 290 is located on the side of the second driving wheel 220 close to the second driven wheel 230, and the elastic member (not shown in the figure) is sleeved on the guide shaft 290, thereby realizing the positioning installation of the elastic member.

[0055] In some embodiments, the material conveying device includes an interval detector, which is arranged along the conveying route of the material 900 and is used to detect the conveying interval of the material 900. The interval detector can transmit the interval information to the adjustment component via a communication connection to feedback and adjust the linear speed of the second conveyor belt 210.

[0056] Specifically, the interval detector may adopt a CCD to detect the interval through image recognition, or may adopt a photoelectric sensor, which is not limited in the present application.
