Detailed Implementation

[0024] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0025] Embodiments of this application provide a material adding device 10, such as... Figure 1 and Figure 4 As shown, the material adding device 10 includes: a hopper 100, a discharge plate 200, a pusher plate 300, and a first driving member 400. The bottom of the hopper 100 has a feed inlet, the discharge plate 200 is disposed opposite to the feed inlet, and the discharge plate 200 has a discharge outlet 210. The pusher plate 300 is slidably connected to the discharge plate 200 and is used to close or open the feed inlet. The first driving member 400 is connected to the pusher plate 300 and is used to drive the pusher plate 300 to reciprocate, so that the pusher plate 300 pushes the material on the discharge plate 200 into the discharge outlet 210.

[0026] In this embodiment, the material is a solid sample; for example, the material may be benzoic acid. The hopper 100 is used to contain the material. The hopper 100 has a cylindrical structure. The material enters the hopper 100 through the top opening and exits the hopper 100 through the bottom inlet. The top of the hopper 100 is provided with a sealing plate that can open or close the top opening.

[0027] The discharge plate 200 is located below the feed inlet. This plate intercepts material falling from the feed inlet, ensuring it lands on the discharge plate 200 after leaving the hopper 100. The discharge port 210 on the discharge plate 200 is horizontally spaced from the feed inlet. A pusher plate 300 is located on the side of the discharge plate 200 closest to the feed inlet. The drive end of the first drive unit 400 is connected to the pusher plate 300, enabling the pusher plate 300 to reciprocate on the discharge plate 200. Figure 4 The arrow at position M points to the direction of movement of the pusher plate 300. The pusher plate 300 can block or avoid the feed inlet to open or close the hopper 100.

[0028] The first driving component 400 is initially extended outwards. At this time, the pusher plate 300 closes the feed inlet and seals the hopper 100. When material is added, the driving end of the first driving component 400 retracts inwards, and the material automatically falls onto the drop plate 200. The driving end of the first driving component 400 then extends outwards, driving the pusher plate 300 forward and pushing the material on the drop plate 200 into the discharge port 210, thus completing the material addition operation. Simultaneously, the pusher plate 300 continues to close the feed inlet, keeping the material within the hopper 100.

[0029] The first drive unit 400 and the pusher plate 300 enable automatic material addition, reducing manual operation, saving labor costs, and avoiding safety hazards caused by manual operation. Furthermore, it minimizes material contact with the outside environment during the addition process, preventing material contamination and ensuring the accuracy of material test results. In addition, the pusher plate 300 can close and seal the hopper 100 while completing the material addition action, achieving two functions in one operation and effectively improving material addition efficiency.

[0030] For example, the first drive element 400 may be a pneumatic cylinder or a hydraulic cylinder.

[0031] In some embodiments provided in this application, such as Figure 3 As shown, optionally, the material adding device 10 further includes a sealing element 500, which is connected to the hopper 100 and surrounds the outer periphery of the feed inlet. When the pusher plate 300 closes the feed inlet, the pusher plate 300 abuts against the sealing element 500.

[0032] In this embodiment, the sealing element 500 is located at the bottom of the hopper 100 and surrounds the outer periphery of the feed inlet. When the pusher plate 300 closes the feed inlet, the pusher plate 300 seals the hopper 100 by abutting against the sealing element 500, thereby preventing material from leaking from the feed inlet.

[0033] For example, the seal 500 can be a sealing ring made of polyurethane or rubber.

[0034] In some embodiments provided in this application, such as Figure 4 As shown, optionally, the material adding device 10 further includes a baffle 600, which is connected to the discharge plate 200 and is located on the side of the discharge port 210 away from the pusher plate 300.

[0035] In this embodiment, a baffle 600 is provided above the discharge plate 200. The baffle 600 is located on the side of the discharge port 210 away from the pusher plate 300, so that when the material is pushed again, it can touch the baffle 600 and fall into the discharge port 210. The baffle 600 limits the position of the material on the discharge plate 200 and cooperates with the pusher plate 300 to improve the falling efficiency of the material.

[0036] In some embodiments provided in this application, such as Figure 4 As shown, optionally, the baffle 600 includes a bending portion 610 and an intercepting portion 620. The bending portion 610 surrounds the outer periphery of the discharge port 210, and the intercepting portion 620 is connected to the end of the bending portion 610 and extends in a direction away from the bending portion 610.

[0037] In this embodiment, the curved portion 610 is disposed around the periphery of the discharge port 210 and surrounds a portion of the discharge port 210. The curvature of the curved portion 610 is less than or equal to the curvature of the discharge port 210. The sidewall of the curved portion 610 can be coplanar with the sidewall of the discharge port 210, so that the shape of the curved portion 610 matches that of the discharge port 210, thus preventing material from accumulating in the curved portion 610.

[0038] The end of the curved portion 610 is provided with an intercepting portion 620, which extends away from the curved portion 610, thereby expanding the interception range of the baffle 600 on the material and improving the interception effect of the baffle 600.

[0039] For example, there are two interception units 620, and the two interception units 620 extend in a direction away from each other.

[0040] In some embodiments provided in this application, such as Figure 4 As shown, optionally, the first end of the pusher plate 300 is connected to the first drive member 400, the second end of the pusher plate 300 is used to push the material, and the pusher plate 300 is provided with an inclined surface 320 on the side near the feed port. The inclined surface 320 extends obliquely towards the direction near the drop plate 200 along the direction from the first end to the second end.

[0041] In this embodiment, the top surface of the pusher plate 300 is a downwardly sloping surface 320. The distance between the sloping surface 320 and the discharge plate 200 gradually decreases in the pushing direction, making the height of the first end of the pusher plate 300 greater than the height of the second end. Material falling onto the pusher plate 300 can automatically slide down the sloping surface 320 into the discharge port 210, improving discharge efficiency. Furthermore, the pusher plate 300 forms a flat shovel shape, enhancing the pushing and shoveling effect. Additionally, the sloping surface 320 cooperates with the sealing element 500, enabling vertical compression of the sealing element 500, thus improving its sealing effect.

[0042] In some embodiments provided in this application, such as Figure 4 As shown, optionally, the second end of the pusher plate 300 is provided with a notch 310, which avoids the discharge port 210.

[0043] In this embodiment, the second end of the pusher plate 300 is provided with a notch 310. The outer dimensions of the notch 310 are greater than or equal to the diameter of the discharge port 210, so that the pusher plate 300 can avoid the discharge port 210 through the notch 310 during the pushing process, and avoid the pusher plate 300 from hindering the material from entering the discharge port 210.

[0044] In some embodiments provided in this application, such as Figure 1 and Figure 5 As shown, optionally, the material adding device 10 further includes: a receiving plate 710 and a second driving member 720. The receiving plate 710 is located on the side of the discharge plate 200 away from the hopper 100, and the receiving plate 710 can face the discharge port 210. The receiving plate 710 is used to place the container 20. The second driving member 720 is connected to the discharge plate 200 and is used to drive the receiving plate 710 to reciprocate.

[0045] In this embodiment, a receiving plate 710 and a second driving member 720 are provided below the discharge plate 200. The receiving plate 710 is used to place the container 20. For example, the container 20 may be a crucible clamp. The driving end of the second driving member 720 is connected to the receiving plate 710 and drives the receiving plate 710 to reciprocate between the receiving position and the designated position.

[0046] When material is added, the drive end of the second drive unit 720 extends outward, driving the receiving plate 710 to a designated position, whereby a container 20 is placed on the receiving plate 710 via an external device. Then, the drive end of the second drive unit 720 retracts inward, driving the receiving plate 710 to a receiving position, placing it below the discharge port 210. The material flows out of the discharge port 210 and falls into the container 20. Through the receiving plate 710 and the second drive unit 720, automatic material loading is achieved, reducing manual operation.

[0047] In some embodiments provided in this application, such as Figure 2 and Figure 3 As shown, optionally, the material adding device 10 further includes: a pallet 810 and a support plate 820. The pallet 810 is connected to the hopper 100, and the bottom of the hopper 100 passes through the pallet 810. The two ends of the support plate 820 are respectively connected to the pallet 810 and the discharge plate 200, and the support plate 820 extends along the movement direction of the pusher plate 300.

[0048] In this embodiment, the pallet 810 is connected to the bottom of the hopper 100. The pallet 810 has a through hole through which the hopper 100 passes. A seal 500 is disposed on the pallet 810. The pallet 810 and the discharge plate 200 are connected by a support plate 820, creating a gap between the feed inlet and the discharge plate 200, allowing the pusher plate 300 to reciprocate between the feed inlet and the discharge plate 200. The support plate 820 is located on one side of the pusher plate 300 and avoids the movement path of the pusher plate 300. The support plate 820 extends along the movement direction of the pusher plate 300 to limit the material falling onto the discharge plate 200 and prevent the material from scattering outwards.

[0049] For example, the number of support plates 820 is at least two, and the pusher plate 300 is located between the two support plates 820.

[0050] In some embodiments provided in this application, such as Figure 2 and Figure 3 As shown, optionally, the material adding device 10 further includes a reinforcing member 830, which is connected to the bottom of the pallet 810 and the hopper 100 respectively.

[0051] In this embodiment, a reinforcing member 830 is provided at the bottom of the connecting pallet 810 and the hopper 100 to improve the connection strength between the pallet 810 and the hopper 100 and ensure the stability of the material adding device 10.

[0052] For example, the shape of the reinforcing member 830 can be triangular or L-shaped, the reinforcing member 830 can be angle steel or reinforcing rib, and the number of reinforcing members 830 can be multiple, with multiple reinforcing members 830 evenly distributed along the circumference of the hopper 100.

[0053] In some embodiments provided in this application, such as Figure 5 As shown, optionally, the material adding device 10 further includes: a bracket 840 and / or a vibration motor, the bracket 840 being connected to the side of the discharge plate 200 away from the hopper 100, the vibration motor being connected to the hopper 100, and the vibration motor being used to drive the hopper 100 to vibrate.

[0054] In this embodiment, the bracket 840 is located at the bottom of the blanking plate 200 and is used to provide structural support for the blanking plate 200 to ensure the stability of the blanking process.

[0055] For example, there can be multiple supports 840, and the material adding device 10 also includes a connector, the two ends of which are connected to adjacent supports 840, further improving the stability of the supports 840.

[0056] The vibration motor is connected to the hopper 100. The vibration motor is used to drive the hopper 100 to vibrate, so that the material in the hopper 100 is vibrated and can leave the hopper 100 more easily, thereby improving the falling efficiency and feeding effect of the material in the hopper 100.

[0057] In some embodiments provided in this application, the material adding device 10 may optionally include two limiting members, one of which is located on the side of the discharge plate 200 near the hopper 100 and connected to the discharge plate 200. The two limiting members are located on both sides of the movement path of the pusher plate 300, and the two ends of the limiting members are connected to the support plate 820 and the baffle 600, respectively.

[0058] In this embodiment, the limiting member is located above the dropping plate 200 and extends along the movement direction of the pusher plate 300 to limit the material falling on the dropping plate 200 and prevent the material from scattering outward.
