Description

Technical Field

[0001] This utility model belongs to the field of reaction cup feeding technology, specifically relating to a vibration mechanism and a hopper assembly and feeding device using the same. Background Technology

[0002] Analytical instruments often use a large number of reaction cups. During the transportation of reaction cups, they are usually placed in a hopper assembly. When the reaction cups are in the hopper assembly, a large number of reaction cups gather together, especially near the bottom. The accumulation of a large number of reaction cups causes them to be difficult to move due to mutual compression and friction, making it difficult to complete the selection of cups smoothly, reducing the selection speed, and thus affecting the speed of instrument analysis. Utility Model Content

[0003] The purpose of this invention is to provide a vibration mechanism and a hopper assembly and feeding device using the same, which aims to solve the problem in the prior art where the hopper assembly cannot smoothly complete the cup selection due to the accumulation of reaction cups, thus reducing the cup selection speed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A vibration mechanism for vibrating a reaction cup in a hopper assembly includes a drive member, a cup-pulling member, and a connecting member. One end of the connecting member is connected to the cup-pulling member, and the other end of the connecting member is connected to the drive member. The cup-pulling member extends into the hopper assembly. In use, the drive member drives the connecting member to rotate around it, while simultaneously causing the cup-pulling member to vibrate the reaction cup.

[0006] In some embodiments, the drive member performs circumferential or horizontal motion to drive the connector to rotate.

[0007] In some embodiments, when the drive member performs circumferential motion, the drive member is a disc cam or a cylindrical cam; when the drive member performs horizontal motion, the drive member is a traverse cam.

[0008] In some embodiments, the cup-dispensing component includes a cup-dispensing part, a reset part, and a fixing part. The cup-dispensing part is connected to the fixing part through the reset part. The fixing part is disposed on the hopper assembly. The cup-dispensing part is connected to the connecting member.

[0009] In some embodiments, one end of the cup-dispensing portion away from the fixing portion extends into the hopper assembly and contacts the reaction cup therein.

[0010] In some embodiments, the vibration mechanism further includes a power element, and the drive element is connected to the power element.

[0011] This utility model adopts another technical solution: a hopper assembly, including the aforementioned vibration mechanism and a cup storage bin, wherein the upper part of the cup storage bin is provided with a cup inlet, and the vibration mechanism is located below the cup inlet.

[0012] This utility model adopts another technical solution: a feeding device, including the aforementioned hopper assembly, cup feeding assembly, and conveying assembly. The cup storage bin is provided with a cup outlet on the side near the conveying assembly. The hopper assembly is connected to the conveying assembly through the cup outlet. The cup feeding assembly pushes the reaction cup in the hopper assembly into the conveying assembly through the cup outlet. In use, the vibration mechanism vibrates the reaction cup in the cup storage bin, and the reaction cup then falls and is pushed into the conveying assembly by the cup feeding assembly.

[0013] In some embodiments, the cup storage compartment has a notch on the side near the cup delivery component, and the notch corresponds to the cup-dispensing component.

[0014] In some embodiments, the cup delivery assembly includes a pusher plate that slides within the cup storage chamber to push the reaction cup from the cup outlet into the delivery assembly.

[0015] Compared with the prior art, in use, the driving component drives the connecting component to swing and move, while driving the cup-pulling component to vibrate the reaction cup in the hopper assembly, so that the reaction cup will not accumulate in the hopper assembly and can fall smoothly into the next process.

[0030] Example 1

[0031] Embodiment 1 of this utility model provides a vibration mechanism for vibrating the reaction cup in a vibrating hopper assembly, such as... Figure 1 and Figure 2 As shown, it includes a driving component 111, a cup-pulling component 112, and a connecting component 113. One end of the connecting component 113 is connected to the cup-pulling component 112, and the other end of the connecting component 113 is connected to the driving component 111. The cup-pulling component 112 extends into the hopper assembly. In use, the driving component 111 drives the connecting component 113 to rotate around it, while simultaneously causing the cup-pulling component 112 to vibrate the reaction cup.

[0032] After adopting the above solution, the driving component 111 drives the connecting component 113 to rotate around it, and at the same time drives the cup-pulling component 112 to vibrate the reaction cup in the hopper assembly, so that the reaction cup will not accumulate in the hopper assembly, and the reaction cup can fall smoothly into the next process.

[0033] Furthermore, the driving member 111 drives the connecting member 113 to rotate around it, ultimately resulting in the connecting member 113 moving up and down relative to each other on horizontal planes at different heights, rather than moving vertically.

[0034] In the specific implementation process of this embodiment 1, such as Figure 1-6 As shown, the driving component 111 performs circumferential or horizontal motion, causing the connecting component 113 to rotate.

[0035] More specifically, such as Figure 2 and Figure 6 As shown, the connector 113 contacts the outer periphery of the drive member 111, and the drive member 111 performs circumferential movement, thereby enabling the connector 113 to rotate around the drive member 111; as Figure 4As shown, the connector 113 contacts the upper or lower end face of the drive member 111, and the drive member 111 moves horizontally, thereby enabling the connector 113 to rotate around the drive member 111.

[0036] In the specific implementation process of this embodiment 1, such as Figure 2 and Figure 6 As shown, when the driving member 111 performs circumferential movement, the driving member 111 is a disc cam or a cylindrical cam; as Figure 4 As shown, when the drive member 111 moves horizontally, the drive member 111 is a moving cam.

[0037] More specifically, the drive component 111 can be connected to the power component to drive its movement; when the drive component 111 is a disc cam or a cylindrical cam, the drive component 111 can be connected to the cup feeding assembly 2. During the process of pushing the reaction cup up and down to the conveying assembly 3, the cup feeding assembly 2 synchronously drives the drive component 111 to rotate, thereby saving device space and power device.

[0038] Furthermore, one embodiment of the drive element 111 is as follows: Figure 2 As shown, the driving component 111 is a disc-shaped part with a recess on one side, so that when the connecting component 113 contacts the circumference of the driving component 111, the driving component 111 rotates while the circumference of its surface is different, which causes the connecting component 113 to drive the cup-pulling component 112 to vibrate the reaction cup while rotating.

[0039] Furthermore, another embodiment of the drive element 111 is, for example... Figure 6 As shown, the driving member 111 is a disc-shaped component with recesses on all four sides. When the connecting member 113 contacts the circumference of the driving member 111, the different circumferential surfaces of the driving member 111 cause the connecting member 113 to simultaneously rotate, driving the agitator 112 to vibrate the reaction cup. In other embodiments, the driving member 111 may also be a disc-shaped component with recesses on two, three, or more than four sides, and the driving member may also be an irregular disc.

[0040] Furthermore, while the driving component 111 is moving in a circumferential direction, the connecting component 113 comes into contact with the driving component 111, and the connecting component 113 rotates accordingly, thereby driving the cup-pulling component 112 to shake or vibrate the reaction cup.

[0041] Furthermore, another embodiment of the drive element 111 is, for example... Figure 4 As shown, the driving component 111 is a component with a stepped surface on the upper or lower end face. When the connecting component 113 contacts the stepped surface of the driving component 111, the driving component 111 moves horizontally while the connecting component 113 moves horizontally, and due to the uneven height of the stepped surface, it drives the cup-pulling component 112 to vibrate the reaction cup.

[0042] In the specific implementation process of this embodiment 1, such as Figure 2 As shown, the cup-dispensing component 112 includes a cup-dispensing part 1121, a reset part 1122, and a fixing part 1123. The cup-dispensing part 1121 is connected to the fixing part 1123 through the reset part 1122. The fixing part 1123 is disposed on the hopper assembly. The cup-dispensing part 1121 is connected to the connecting member 113.

[0043] More specifically, the drive member 111 rotates, causing the connecting member 113 to rotate around it. The connecting member 113 simultaneously drives the cup-pulling part 1121 to move. When the connecting member 113 moves to the highest position, the reset part 1122 resets the cup-pulling part 1121. The fixing part 1123 is provided on the hopper assembly. One end of the reset part 1122 is connected to the fixing part 1123, and the other end of the reset part 1122 is connected to the cup-pulling part 1121, which enables the cup-pulling part 1121 to be reset better.

[0044] Furthermore, the reset part 1122 is a reset spring or other component that performs a reset function.

[0045] In the specific implementation process of this embodiment 1, such as Figure 2 As shown, one end of the cup-dispensing part 1121, away from the fixing part 1123, extends into the hopper assembly and contacts the reaction cup therein.

[0046] More specifically, the end of the cup-dispensing part 1121 away from the fixed part 1123 extends into the hopper assembly and contacts the reaction cup therein. In the non-working state, the cup-dispensing part 1121 is flush with the inner wall of the hopper assembly, ensuring that the cup-dispensing part 1121 can contact the reaction cup. In the working state, the cup-dispensing part 1121 is higher than the inner wall of the hopper assembly. As the drive member 111 drives, the cup-dispensing part 1121 gradually falls back to be flush with the inner wall of the hopper assembly, thereby achieving the effect of vibrating the reaction cup, so that the reaction cup can fall smoothly.

[0047] In the specific implementation process of this embodiment 1, such as Figure 3 and Figure 6 As shown, the vibration mechanism also includes a power component 114, and the drive component 111 is connected to the power component 114.

[0048] More specifically, the power component 114 can be a motor or other component capable of driving the drive component 111 to rotate, and the power component 114 drives the drive component 111 to move in a circumferential direction.

[0049] Furthermore, such as Figure 3As shown, when the driving component 111 is a component with a stepped surface on its upper or lower end face, the driving component 111 is located on one side of the hopper assembly. The driving component 111 is connected to the power component 114. The power component 114 is a component capable of driving the driving component 111 to move horizontally. The power component 114 includes a first synchronous belt 1141, a first driving pulley 1142, a first driven pulley 1143, and a first motor 1144. The first motor 1144 is mounted on a fixed frame. The first driving pulley 1142 and the first driven pulley 1143... A driven wheel 1143 is horizontally arranged and spaced apart on the fixed frame. The first driving wheel 1142 is connected to the output shaft of the first motor 1144. The first synchronous belt 1141 is sleeved on the first driving wheel 1142 and the first driven wheel 1143. The first synchronous belt 1141 is connected to the driving member 111. When the first motor 1144 moves, the driving member 111 can be driven to move horizontally through the first synchronous belt 1141, thereby driving the cup-pulling member 112 to vibrate the reaction cup.

[0050] The working process provided in Embodiment 1 of this utility model is as follows: In use, the driving member 111 drives the connecting member 113 to rotate around it. The end of the cup-pulling part 1121 away from the fixed part 1123 passes through the hopper assembly and contacts the reaction cup therein. In the non-working state, the cup-pulling part 1121 is flush with the inner wall of the hopper assembly, ensuring that the cup-pulling part 1121 can contact the reaction cup. In the working state, the cup-pulling part 1121 is higher than the inner wall of the hopper assembly. As the driving member 111 drives, the cup-pulling part 1121 gradually falls back to be flush with the inner wall of the hopper assembly, thereby achieving the effect of vibrating the reaction cup, so that the reaction cup can fall smoothly.

[0051] Example 2

[0052] Embodiment 2 of this utility model provides a hopper assembly, such as Figure 1 As shown, it includes a vibration mechanism 11 and a cup storage compartment 12 as described in Embodiment 1. The upper part of the cup storage compartment 12 is provided with a cup inlet 121, and the vibration mechanism 11 is located below the cup inlet 121.

[0053] Example 3

[0054] The feeding device provided in Embodiment 3 of this utility model is as follows: Figure 7 and Figure 8As shown, the assembly includes a hopper assembly 1, a cup feeding assembly 2, and a conveying assembly 3 as described in Embodiment 2. The cup storage chamber 12 has a cup outlet 122 on the side near the conveying assembly 3. The hopper assembly 1 is connected to the conveying assembly 3 through the cup outlet 122. The cup feeding assembly 2 pushes the reaction cup in the hopper assembly 1 into the conveying assembly 3 through the cup outlet 122. In use, the vibration mechanism 11 vibrates the reaction cup in the cup storage chamber 12, and the reaction cup falls down and is pushed into the conveying assembly 3 by the cup feeding assembly 2.

[0055] After adopting the above scheme, when in use, a large number of reaction cups are put into the cup inlet 121. The reaction cups fall into the cup storage chamber 12 along the hopper assembly. The vibration mechanism 11 vibrates the reaction cups in the cup storage chamber 12. The reaction cups then fall down and are pushed into the conveying assembly 3 by the cup feeding assembly 2.

[0056] Furthermore, such as Figure 8 As shown, when the cup feeding assembly 2 pushes the reaction cup to the outlet 122, the reaction cup can enter the conveying assembly 3 from the outlet 122.

[0057] In the specific implementation process of this embodiment 3, such as Figure 7 As shown, the cup storage compartment 12 has a notch 123 on the side near the cup delivery component 2, and the notch 123 corresponds to the cup dispensing component 112.

[0058] More specifically, the cup storage compartment 12 has a notch 123 on the side near the cup delivery component 2. The notch 123 corresponds to the cup pusher 112, so that the reaction cup in the hopper assembly will not fall out of the hopper assembly.

[0059] Furthermore, the cup storage compartment 12 also includes a partition 124, such as... Figure 10 and Figure 11 As shown, the partition 124 divides the storage cup chamber 12 into a temporary storage chamber 12a and a working chamber 12b. A large number of reaction cups are poured in and sequentially enter the temporary storage chamber 12a and the working chamber 12b. The working chamber 12b comes into contact with the cup delivery assembly 2. The vibration mechanism 11 is used to vibrate the reaction cups in the working chamber 12b, so that the reaction cups move orderly from the temporary storage chamber 12a to the working chamber 12b, and the reaction cups are not all poured into the working chamber 12b at once, nor are they accumulated in the temporary storage chamber 12a without sliding into the working chamber 12b. More specifically, the cup-pulling component 112 extends into the working chamber 12b, and the driving component 111 drives the cup-pulling component 112 to vibrate the reaction cups in the working chamber 12b, ensuring that there is always an appropriate amount of reaction cups in the working chamber 12b, so that the reaction cups in the working chamber 12b fall in an orderly manner to ensure that the cup delivery assembly 2 picks up the reaction cups, and at the same time, there is no accumulation that would cause the cup delivery assembly 2 to jam.

[0060] In the specific implementation process of this embodiment 3, such as Figure 9 As shown, the cup delivery assembly 2 includes a push plate 21, which slides within the cup storage chamber 12 to push the reaction cup from the cup outlet 122 into the delivery assembly 3.

[0061] More specifically, the cup delivery assembly 2 includes a pusher plate 21, which pushes the reaction cup from the outlet 122 into the delivery assembly 3.

[0062] Furthermore, the push plate 21 is provided with an arc-shaped guide surface 211 at the contact point with the reaction cup, so that the push plate 21 will not cause wear to the reaction cup during the process of pushing the reaction cup; in other embodiments, the end of the push plate 21 near the reaction cup can also be set as a roller (not shown in the figure), so that the push plate 21 will not cause wear to the reaction cup during the process of pushing the reaction cup; or it can be set in other ways that will not cause wear to the reaction cup.

[0063] Furthermore, such as Figure 9 As shown, the cup feeding assembly 2 also includes a driver 22 and a base 23. The driver 22 is used to drive the push plate 21 to slide up and down within the cup storage compartment 12. The driver 22 includes a second synchronous belt 221, a second driving wheel 222, a second driven wheel 223, and a second motor 224. The second motor 224 is mounted on the base 23. The second driving wheel 222 and the second driven wheel 223 are vertically arranged and spaced apart on the base 23. The second driving wheel 222 is connected to the output shaft of the second motor 224. The second synchronous belt 221 is sleeved on the second driving wheel 222 and the second driven wheel 223. The push plate 21 is connected to the second synchronous belt 221 and is slidably connected to the base 23. When the second motor 224 moves, the push plate 21 can be driven to slide up and down relative to the base 23 via the second synchronous belt 221, allowing the push plate 21 to slide up and down within the cup storage compartment 12.

[0064] Furthermore, the end of the second driven wheel 223 near the base 23 is connected to the second driving wheel 222 via the second synchronous belt 221, and the end of the second driven wheel 223 away from the base 23 is connected to the drive member 111. This allows the push plate 21 to push the reaction cup, while the drive member 111 drives the cup-pulling member 112 to vibrate the reaction cup in the hopper assembly. The second motor 224 can serve two purposes, saving space in the device.

[0065] In summary, when this utility model is in use, the driving component 111 drives the connecting component 113 to rotate around it, and at the same time drives the cup-pulling component 112 to vibrate the reaction cup in the hopper assembly, so that the reaction cup will not accumulate in the hopper assembly, and the reaction cup can fall smoothly into the next process.

[0066] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
