Description

Technical Field

[0001] This utility model relates to the field of counting devices, and in particular to a silent material counting device. Background Technology

[0002] In existing counting devices used for precise control of material feeding quantity, the conveying mechanism often uses a vibrating table to drive the material to be transported towards the feeding mechanism in a shaking manner.

[0003] However, the above-mentioned technologies have at least the following technical problems:

[0004] Vibration tables generate a lot of noise when they are working, and counting devices are often formed by multiple conveying mechanisms connected in series. The simultaneous operation of multiple vibration tables will generate a lot of noise pollution. Utility Model Content

[0005] The purpose of this invention is to provide a silent material counting device to solve the problem of excessive noise in existing counting devices.

[0006] The technical solution of this utility model is: a silent material counting device, including a base, on which a conveying mechanism is provided. The conveying mechanism is constructed as a first conveying channel and a second conveying channel arranged side by side. The first conveying channel and the second conveying channel operate independently, and the width of the second conveying channel is smaller than the width of the first conveying channel. Multiple conveying mechanisms with successively decreasing heights form a conveying assembly.

[0007] Any conveying mechanism includes a conveyor belt for carrying materials, and conveyor pulleys are connected to both ends of the conveyor belt. The conveyor pulleys rotate around their own axis under the drive of the conveyor driver and drive the conveyor belt to run.

[0008] Preferably, there is a vertical gap between conveying mechanisms at adjacent heights, the gap being configured as a counting channel, and a visual inspection device is provided corresponding to the counting channel. The detection end of the visual inspection device passes through the counting channel to obtain the quantity of material passing through the counting channel.

[0009] Preferably, the end of the conveying component is provided with a feeding mechanism, which includes a feeding conveyor belt. The feeding conveyor belt is arranged perpendicular to the length direction of the conveying component and runs under the drive of the feeding conveyor belt pulley, and is used to receive the material conveyed by the conveying component.

[0010] Preferably, at least one end of the feeding conveyor belt is provided with a feeding baffle in the vertical direction. The feeding baffle moves up and down under the drive of the baffle driver, so that the material is detached from one end of the feeding mechanism or retained in the feeding mechanism.

[0011] Preferably, a material straightening mechanism is provided at the head end of the corresponding conveying component. The material straightening mechanism includes a material straightening roller suspended above the conveying component. The material straightening roller has a horizontally set axis, and the closest distance between the material straightening roller and the conveying component is less than the minimum height of two materials stacked together.

[0012] Preferably, the material roller is connected to a material driver, which can drive the roller to rotate around its own axis, and the direction of movement of the point on the material roller closest to the conveying component is opposite to the direction of movement of the conveying component.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] (1) The conveying mechanism in this application consists of a conveyor belt and a conveyor pulley. Compared with the material feeding method of the vibrating table in the prior art, the conveyor belt and the conveyor pulley run more smoothly and do not generate excessive noise, thereby optimizing the working environment.

[0015] (2) This application has a material sorting mechanism at the beginning of the conveying component, which can avoid the problem that multiple materials are stacked and the visual inspection device cannot accurately identify the quantity of materials. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0024] The present invention will be further described in detail below with reference to specific embodiments:

[0025] like Figures 1-3 As shown, a silent material counting device includes a base with a conveying mechanism 1 mounted on it. The conveying mechanism 1 is used to feed multiple materials provided by a front-end feeding device into a discharging mechanism 5 in the required quantity. The conveying mechanism 1 is configured as a first conveying channel 1a and a second conveying channel 1b arranged side by side. The first conveying channel 1a and the second conveying channel 1b operate independently at the same speed, and the width of the second conveying channel 1b is smaller than the width of the first conveying channel 1a, preferably ensuring that it conveys at most one part at any given length. When the quantity of material to be conveyed approaches a preset value, the operation of the first conveying channel 1a is stopped, and only the second conveying channel 1b operates at a low flow rate. This prevents multiple materials from running side-by-side on the second conveying channel 1b and simultaneously entering the discharging mechanism 5, thus avoiding exceeding the preset value of the conveyed material quantity.

[0026] To avoid excessive density caused by placing a large amount of material in the same conveyor mechanism 1, which could lead to material behind the second conveyor channel 1b being pushed into the feeding mechanism 5 by inertia when the second conveyor channel 1b stops, resulting in inaccurate feeding, this application arranges multiple conveyor mechanisms 1 in a descending order of height to form a conveying assembly. When the amount of material fed reaches a preset value of A%, the two first conveyor channels 1a are closed, leaving only the two second conveyor channels 1b for material conveying; when it reaches a preset value of B% (B>A), the upper second conveyor channel 1b is closed, leaving only the lower second conveyor channel 1b for feeding material until the feeding quantity reaches the preset value.

[0027] In this embodiment, the conveying mechanism 1 includes a conveyor belt 11, which is used to carry materials. The two ends of the conveyor belt 11 are connected to conveyor pulleys 12. The conveyor pulleys 12 rotate around their own axis under the drive of the conveying driver 13 and drive the conveyor belt 11 to run.

[0028] like Figure 3As shown, the quantity of materials is counted in the following way: there is a vertical gap between the conveying mechanisms 1 at adjacent heights, which is constructed as a counting channel 2. A visual inspection device 3 is set up corresponding to the counting channel 2. The visual inspection device 3 has a transmitting end 3a and a receiving end 3b. The line connecting the transmitting end 3a and the receiving end 3b passes through the counting channel 2, thereby obtaining the quantity of materials passing through the counting channel 2.

[0029] To prevent multiple materials from piling up on the conveying component when the feeding equipment is feeding materials, which would cause the multiple stacked materials to be identified as a single material by the vision detection device 3 when passing through the counting channel 2, resulting in inaccurate feeding, this application provides a material straightening mechanism 4 at the head end of the conveying component.

[0030] Combination Figure 1 and Figure 4 As shown, the material leveling mechanism 4 includes a material leveling roller 41 suspended above the conveying assembly. The material leveling roller 41 has a horizontally arranged axis, and the closest distance between the material leveling roller 41 and the conveying assembly is less than the minimum height of two materials stacked together, so that materials stacked on top of other materials can be blocked by the material leveling roller 41 and fall to the same height. Furthermore, the material leveling roller 41 is connected to a material leveling driver 42, which can drive the roller to rotate around its own axis. Figure 5 As shown, the movement direction of the point on the material-forming roller 41 closest to the conveying component is opposite to the movement direction of the conveying component. This serves to bounce materials stacked on top of other materials, thus achieving a better material-forming effect.

[0031] The feeding mechanism 5 is located at the end of the conveying assembly. The feeding mechanism 5 includes a feeding conveyor belt 51, which is arranged perpendicular to the length direction of the conveying assembly and runs under the drive of the feeding conveyor belt pulley 52. ​​It is used to receive the material conveyed by the conveying assembly. Feeding baffles 53 are arranged vertically at both ends of the feeding conveyor belt 51. The feeding baffles 53 move up and down under the drive of the baffle driver 54, so that the material is detached from one end of the feeding mechanism 5 or retained in the feeding mechanism 5.

[0032] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
