Detailed Description of the Embodiments

[0037] In industrial production, the following two automation methods are usually adopted to mix these raw materials in different forms: 1) Mix multiple raw materials in advance and then sub-pack; 2) Weigh each raw material separately and then mix and bag. Among them, the disadvantage of the first method is that the error is relatively large and the content of each raw material cannot be monitored. When implementing the second method, multiple multi-head scales (also known as computer combination scales) are often used to weigh the raw materials separately, and the cost of the multi-head scale is relatively high, and it occupies a large area and is not convenient to clean.

[0038] Therefore, both of the above two automation methods are difficult to balance cost and accuracy.

[0039] To solve this problem, the present utility model provides a feeding device, and a feeding counting component is arranged in the feeding device. The feeding counting component can realize feeding by counting, thereby reducing the cost. Moreover, by adjusting the size of the tray discharge port, the requirement of feeding accuracy can be achieved.

[0040] To make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given with reference to the accompanying drawings.

[0041] Referring to Figure 1 , an embodiment of the present utility model provides a feeding device, and the feeding device includes:

[0042] Bracket 11;

[0043] Storage bin 12, located on the bracket 11, for storing materials;

[0044] Feeding assembly 13, for feeding materials to the tray 14;

[0045] The tray 14 is used for performing the feeding operation; the tray 14 has a tray discharge port;

[0046] The storage bin 12, the feeding assembly 13 and the tray 14 are located on the bracket 11;

[0047] Wherein, the feeding device further includes: a feeding counting assembly; the feeding counting assembly is located in the tray and is used for feeding a preset number of materials into the discharge port; the size of the tray discharge port matches the size of the preset number of materials.

[0048] By adjusting the size of the tray discharge port so that the size of the tray discharge port matches the size of the preset number of materials, in this way, the quantitative feeding can be realized by calculating the number of materials fed into the tray discharge port without weighing, thereby reducing the cost and ensuring the feeding accuracy.

[0049] In the embodiment of the present utility model, the materials include but are not limited to spherical or quasi-spherical granular raw materials, such as green beans, peas, peanuts, chickpeas, etc.

[0050] In a specific implementation, the bracket 11 is used to support other components of the feeding device, and the specific shape is not limited as long as it can provide a horizontal support surface 11a. The storage bin 12, the feeding assembly 13 and the tray 14 are all located above the horizontal support surface 11a of the bracket 11.

[0051] In a specific implementation, the storage bin 12 can be in a funnel shape. The storage bin 12 has a storage bin inlet at the upper part, and materials can enter and be stored in the storage bin 12 through the storage bin inlet. The storage bin 12 can have a storage bin outlet at the lower part, and the storage bin outlet is connected to the feeding assembly 13, so that the materials stored in the storage bin 12 can be transported to the tray 14 through the feeding assembly 13.

[0052] In a specific implementation, the feeding assembly 13 can include: a feeding channel and a vibration assembly. One end of the feeding channel is communicated with the storage bin 12, and the other end is communicated with the tray 14. The vibration assembly is connected to the feeding channel, and the vibration assembly can make the feeding channel vibrate.

[0053] Specifically, the vibration assembly can be fixed on the support surface 11a of the bracket 11. The feeding channel can be implemented by a feeding groove. The vibration assembly drives the feeding channel to vibrate, so that the materials output into the feeding channel can be quickly put into the tray 14, improving the feeding efficiency.

[0054] Figure 2 This is a schematic cross-sectional view of the tray 14 in an embodiment of the present invention. Figure 3 A schematic top view of the tray 14 in an embodiment of the present invention. Refer to Figure 2 and Figure 3 In an embodiment of the present invention, the tray 14 may have a tray discharge port 141. A feeding counting assembly may be provided inside the tray 14. The feeding counting assembly can achieve counting and feeding.

[0055] Specifically, the feeding counting assembly may include: a rotating disk 142, a feeding structure 143, and a rotating shaft 144. Among them, the rotating disk 142 is located inside the tray and has a plurality of discharge holes 142a. The feeding structure 143 is connected to the tray 14 and is used to put the materials inside the tray 14 into the discharge holes 142a. The rotating shaft 144 is fixed on the bracket 11 and penetrates the bottom of the tray 14 and the rotating disk 142. The rotating shaft 144 is used to drive the rotating disk 142 to rotate. Figure 3 The discharge holes 142a are not shown in

[0056] In a specific implementation, the feeding counting assembly may further include a driving structure (such as a motor), which is connected to the rotating shaft 144 through the driving structure, thereby driving the rotating shaft 144 to rotate. The rotating disk 142 can be fixedly connected to the rotating shaft 144, including but not limited to being fixedly connected by welding. In this way, when the rotating shaft 144 rotates, the rotating disk 142 can be driven to rotate.

[0057] In a specific implementation, the feeding device may further be provided with a control component, and the control component is used to control the operation of the feeding counting assembly. Specifically, the control component can receive external input information, and then control the driving structure of the feeding counting assembly based on the external input information, so that the rotation frequency and rotation duration of the rotating disk 142, etc., so that the materials finally put into the tray discharge port 141 meet the setting.

[0058] In specific implementation, the materials provided by the feeding channel are usually stacked on the rotating disk 142 below the discharge port of the feeding channel. At least in the area corresponding to the lower part of the discharge port of the feeding channel on the rotating disk 142, discharge holes 142a are provided, and at least part of the stacked materials enter into the discharge holes 142a of the rotating disk 142. When the rotating disk 142 rotates, the redundant materials are blocked by the feeding structure 143, so that there are no redundant materials on the surface of the discharge holes 142a into which the materials enter. When the discharge holes 142a rotate above the discharge port 141, the materials entering the discharge holes 142a will be discharged from the discharge port 141.

[0059] In specific implementation, the feeding structure 143 can be a scraper. The scraper can be fixed on the material tray 14 and pass through the distribution area of the discharge holes 142a. There can be a small gap between the bottom end of the scraper and the surface of the rotating disk 142. When the rotating disk 142 rotates, the scraper can scrape off the redundant materials on the surface of the rotating disk 142, so that there are no redundant materials on the surface of the discharge holes 142a into which the materials enter, thereby controlling the feeding quantity.

[0060] In specific implementation, the number of the scrapers can be one or two, which is not limited here. For example, referring to Figure 3 , the feeding counting assembly can include two scrapers, namely a first scraper 1431 and a second scraper 1432. Both the first scraper 1431 and the second scraper 1432 pass through the distribution area of the discharge holes 142a and are distributed along the rotation direction of the rotating disk 142. Taking the counterclockwise rotation of the rotating disk 142 as an example, after the first scraper 1431 clears the materials on the rotating disk 142 first, the second scraper 1432 then clears the materials on the rotating disk 142, so that the redundant materials on the surface of the rotating disk 142 can be completely removed.

[0061] In specific implementation, by adjusting the size and thickness of the discharge holes 142a to be basically the same as the size of a single material, each discharge hole 142a can only allow one material to enter, and the weight of a single material is basically the same. Therefore, by controlling the number of the discharge holes 142a rotating above the discharge port 141, the quantity of the discharged materials can be controlled, and accurate feeding can be achieved.

[0062] In specific implementation, the feeding device can have multiple rotating disks 142, and each rotating disk 142 has discharge holes of different sizes. By replacing the rotating disk 142, different sizes of materials can be adapted.

[0063] In specific implementation, the distribution of the discharge holes 142a on the rotating disk 142 can be set according to actual needs. In one embodiment, the area of the region where the discharge holes 142a are located can be set to be greater than or equal to the area of the discharge port 141. Thus, a preset quantity of materials can be output through one rotation, improving the feeding efficiency.

[0064] In one embodiment, referring to Figure 4 , the discharge holes 142a can be arranged uniformly in the edge area of the rotating disk 142. Among them, the size of the edge area can be set according to the size of the discharge port 141. Among them, the edge area of the rotating disk 142 refers to: an annular area near the edge of the rotating disk 142 and capable of covering the discharge port 141. The discharge holes 142a are uniformly distributed in the edge area of the rotating disk 142, that is, they are arranged in multiple rings around the center of the rotating disk 142, and the number of discharge holes 142a in each ring distribution is equal. The rotating disk 142 has a plurality of uniformly distributed radial directions, and the discharge holes 142a in the same ring are respectively arranged in each radial direction. In this way, along each radial direction, the same number of discharge holes 142a can be provided, thereby facilitating the control of the number of discharge holes 142a rotated above the discharge port 141 and achieving the purpose of precise feeding.

[0065] In a specific implementation, in order to make the material easier to enter the discharge holes 142a, the rotating disk 142 can be set to be inclined relative to the bottom surface of the material tray 14. Specifically, the distance from the side of the rotating disk 142 close to the discharge port 141 to the side of the rotating disk 142 close to the feeding component can be set to decrease from large to small with respect to the bottom surface of the material tray 14, so that the material is easier to accumulate on the side of the rotating disk 142 close to the feeding component, and it is easier for the material to enter the discharge holes 142a.

[0066] In a specific implementation, after the rotating disk 142 is selected, by adjusting the size of the discharge port 141 of the material tray, the feeding amount can be changed, so as to precisely control the feeding amount.

[0067] In one embodiment, the material tray 14 may further include: a discharge port adjustment structure for adjusting the size of the discharge port of the material tray. Specifically, the discharge port adjustment structure can be located on one side of the discharge port 141 of the material tray. The discharge port adjustment structure can be a telescopic structure. By pulling the discharge port adjustment structure to the other side of the discharge port 141 of the material tray, the size of the discharge port of the material tray can be changed, thereby changing the single feeding amount.

[0068] In some embodiments, referring to Figure 1 , the feeding device may further include a first discharge component 15. The first discharge component 15 is connected to the material tray 14 and communicates with the discharge port of the material tray, and is used for outputting the material input to the discharge port of the material tray.

[0069] In a specific implementation, the first discharge component 15 can be a closed discharge chute. The closed discharge chute can be detachably connected to the material tray 14. The material input to the discharge port 141 of the material tray is output through this closed discharge chute.

[0070] In some embodiments, referring toFigure 5 The feeding device may further include a multi-head scale 16. The multi-head scale is fixed on the bracket 11. The multi-head scale 16 may include: a blanking chute, a multi-head scale main body, and a plurality of heads located on the multi-head scale main body. The blanking chute is located above the multi-head scale main body and can supply materials to each head in a vibrating manner. Each head is an individual scale and can weigh independently. The sum of the weights of each head is used as the weighing result of the multi-head scale.

[0071] In a specific implementation, the multi-head scale 16 can be used to weigh various materials such as granular, flaky, strip-shaped, spherical, etc., such as various nuts, pet foods, puffed foods, hardware parts, plastic pellets, etc. It not only has accurate measurement but also high production capacity.

[0072] In a specific implementation, the multi-head scale 16 further includes a second discharging assembly 161. After weighing is completed, the materials weighed in each head are output through the second discharging assembly 161.

[0073] The multi-head scale 16 is fixed on the bracket 11. In this way, two sets of weighing assemblies are arranged on the same bracket. Among them, the method of weighing through the feeding counting assembly in the tray not only has accurate measurement but also occupies less space. After being combined with the multi-head scale 16, it can realize the quantitative feeding of different materials. Compared with using multiple multi-head scales, in the feeding device of the embodiment of the present invention, only one multi-head scale is provided, which occupies a smaller area, saves space, has a lower cost, and is simple to change products.

[0074] Refer to Figure 5 An embodiment of the present invention further provides a feeding system. The feeding system includes the above-mentioned feeding device and a packaging machine 20. The feeding device is used to feed materials into the packaging machine 20, and the packaging machine 20 is used to package the input materials.

[0075] In some embodiments, the feeding system may further include: a feeding hopper 30. The feeding hopper 30 is communicated with the first discharging assembly 15 and the second discharging assembly 161, so that the materials output by the first discharging assembly 15 and the second discharging assembly 161 can be fed into the packaging machine 20 through the feeding hopper 30.

[0076] In a specific implementation, the packaging machine 20 may be provided with a controller. The controller can receive external input information, such as the weighing amount of each material, so as to control the multi-head scale 16 and the feeding counting assembly to work. The multi-head scale 16 and the feeding counting assembly work according to the control of the controller. After weighing different materials, they are simultaneously output to the feeding hopper 30 through the first discharging assembly 15 and the second discharging assembly 161, and then the packaging machine 20 bags the received materials.

[0077] By adopting the feeding system of the present utility model, accurate feeding can be achieved at a relatively low cost, and it occupies less space and is simple to change products.

[0078] Although the present utility model is disclosed as above, the present utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the scope defined by the claims.
