Description

Technical Field

[0001] This utility model relates to the field of tungsten powder processing technology, specifically, a three-stage spiral feeding structure for a tungsten powder packaging machine. Background Technology

[0002] To ensure that tungsten powder is accurately and effectively conveyed or delivered to the next stage during production or processing, a corresponding feeding system is typically used. Most existing tungsten powder packaging machines use a vibratory feeding method. However, this method has a drawback: packaging accuracy and efficiency are mutually exclusive. Achieving high accuracy comes at the cost of lower efficiency, while increasing efficiency reduces accuracy. Therefore, a feeding system that can guarantee both accuracy and efficiency is needed. Utility Model Content

[0003] The purpose of this invention is to provide a three-stage spiral feeding structure for a tungsten powder packaging machine, which solves the current problem that the speed and accuracy of tungsten powder feeding cannot be achieved simultaneously.

[0004] This utility model is achieved through the following technical solution: a three-stage spiral feeding structure for a tungsten powder packaging machine, comprising:

[0005] Mounting frame, used to place and lift the material supply section;

[0006] The feeding section is used for feeding tungsten powder.

[0007] The feeding unit includes a quantitative feeding unit, a screening unit, and a grading supply unit. The grading supply unit is equipped with a secondary output unit and a tertiary output unit, and the tertiary output unit outputs material with higher precision than the secondary output unit. The quantitative feeding unit receives external tungsten powder and conveys it to the screening unit. The screening unit screens the tungsten powder conveyed by the quantitative feeding unit and conveys it to the grading supply unit. The secondary output unit first quickly outputs the tungsten powder conveyed by the screening unit, and then the tertiary output unit accurately outputs the tungsten powder.

[0008] To better realize this utility model, the graded supply unit further includes a feeding pipe, a conveying pipe, and a maintenance bin; the secondary output unit includes a secondary output motor; the tertiary output unit includes a tertiary output motor; the output ends of the tertiary output motor and the secondary output motor are both connected to a spiral conveying rod; the tertiary output motor and the secondary output motor are both mounted on the conveying pipe; the maintenance bin is connected to the output ends of the secondary output unit and the tertiary output unit; and the feeding pipe is connected to the maintenance bin.

[0009] To better realize this utility model, the graded supply unit further includes a second vibration motor, which is attached to the material conveying pipe wall of the maintenance chamber.

[0010] To better realize this utility model, the graded supply unit further includes a buffer bin, which is installed on the mounting frame. The output end of the buffer bin is connected to the conveying pipe, and the material conveyed by the screening unit is received by the buffer bin.

[0011] To better realize this utility model, the quantitative feeding unit further includes a feeding barrel, a primary output section, and a feeding pipe. The feeding barrel is installed on the feeding pipe. The primary output section includes a primary output motor. The output end of the primary output motor is drivenly connected to a spiral conveying rod. The primary output motor is installed on the feeding pipe.

[0012] To better realize this utility model, the screening unit further includes a screening cylinder, a receiving cylinder, a collecting bucket, a material discharge pipe, a slag discharge pipe, and a first vibrating motor. The screening cylinder is installed on the receiving cylinder, and a screen is provided between the screening cylinder and the receiving cylinder. The receiving cylinder and the first vibrating motor are both installed on the mounting frame. The first vibrating motor is drivenly connected to the receiving cylinder. The receiving cylinder is provided with a material discharge pipe, which discharges the material to the grading supply unit. The screening cylinder is provided with a slag discharge pipe, and the collecting bucket is installed on the mounting frame to receive the material discharged from the slag discharge pipe.

[0013] To better realize this utility model, the mounting frame further includes support rods, a placement platform, guardrails, ladders, and a support table. Multiple support rods are installed on the placement platform to increase the height of the placement platform. Guardrails, ladders, and a support table are installed on the placement platform, and the screening unit is installed on the support table.

[0014] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0015] (1) By setting two output sections with different feeding accuracies, when feeding tungsten powder, the secondary output section first outputs the tungsten powder quickly to improve the conveying efficiency; when the tungsten powder packaging section detects that the weight of the tungsten powder is close to the set value, the tertiary output section outputs the tungsten powder accurately to ensure that the tungsten powder packaging section of the next station can receive the precise dose of tungsten powder; thus, the material supply has a fast speed and high feeding accuracy, which greatly improves the efficiency of tungsten powder supply and shortens the operation cycle.

[0016] (2) By setting up a quantitative feeding unit, the conveying speed of the primary output motor depends on the screening speed of the screening unit. The screening efficiency of the screening unit is different for different tungsten powders, so the supply can be adjusted by adjusting the speed of the primary output motor.

[0017] (3) By setting up a screening unit, the tungsten powder is screened before feeding and packaging, which can screen out a small amount of large tungsten powder particles, ensuring that the tungsten powder in subsequent packaging has uniform particle size and high quality.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Example 1:

[0027] This embodiment provides a three-stage spiral feeding structure for a tungsten powder packaging machine, specifically as follows: Figures 1-3 As shown, it includes:

[0028] Mounting frame 10 is used to place and lift the feeding section 20;

[0029] Feeding section 20 is used for tungsten powder feeding;

[0030] The feeding unit 20 includes a quantitative feeding unit 21, a screening unit 22, and a grading supply unit 23. The grading supply unit 23 is equipped with a secondary output unit and a tertiary output unit, and the tertiary output unit outputs materials with higher precision than the secondary output unit. The quantitative feeding unit 21 is used to receive external tungsten powder and transport it to the screening unit 22. The screening unit 22 screens the tungsten powder transmitted by the quantitative feeding unit 21 and transmits it to the grading supply unit 23. The secondary output unit first outputs the tungsten powder transmitted by the screening unit 22 quickly, and then the tertiary output unit outputs the tungsten powder precisely.

[0031] In use, the tungsten powder is first quantitatively fed into the screening unit 22 using the quantitative feeding unit 21. The quantitative feeding of the quantitative feeding unit 21 is designed to match the screening efficiency of the screening unit 22, ensuring that the screening unit 22 operates efficiently without clogging. After screening in the screening unit 22, the tungsten powder is transferred to the grading supply unit 23. The secondary output section of the grading supply unit 23 first outputs the tungsten powder quickly to improve the conveying efficiency. When the tungsten powder packaging section of the next station detects that the weight of the tungsten powder is close to the set value, the tertiary output section outputs the tungsten powder precisely, ensuring that the tungsten powder packaging section of the next station can accept a precise dose of tungsten powder, thus achieving quantitative packaging.

[0032] The coordination of the secondary and tertiary output sections enables faster material supply with higher feeding accuracy, significantly improving the efficiency of tungsten powder supply and shortening the operation cycle.

[0033] Example 2:

[0034] This embodiment further expands upon the hierarchical supply unit 23 based on the above embodiments, specifically as follows: Figures 3-5 As shown, the graded supply unit 23 includes a feeding pipe 231, a conveying pipe 234, and a maintenance chamber 235. The secondary output section includes a secondary output motor 233, and the tertiary output section includes a tertiary output motor 232. The output ends of both the tertiary output motor 232 and the secondary output motor 233 are connected to a spiral conveying rod. The spiral conveying rod on the tertiary output motor 232 has a smaller diameter and a smaller pitch than that on the secondary output motor 233, thereby achieving higher precision supply. The tertiary output motor 232 and the secondary output motor 233 are both mounted on the conveying pipe 234. The maintenance chamber 235 is connected to the output ends of the secondary and tertiary output sections, and the feeding pipe 231 is connected to the maintenance chamber 235. When the three-stage output motor 232 or the two-stage output motor 233 starts, the screw conveyor pushes the material in the conveying pipe 234 to the maintenance chamber 235, and then passes it through the feeding pipe 231 to the next process. The maintenance chamber 235 is equipped with an inspection window, which can be opened for maintenance when necessary.

[0035] Furthermore, the graded supply unit 23 also includes a second vibration motor 236, which is attached to the material conveying pipe wall of the maintenance chamber 235. The vibration of the second vibration motor 236 can prevent tungsten powder from remaining in the maintenance chamber 235, ensuring that all material can be conveyed out through the feed pipe 231 with each feeding, thereby improving feeding accuracy.

[0036] Furthermore, the graded supply unit 23 also includes a buffer bin 230, which is installed on the mounting frame 10. The output end of the buffer bin 230 is connected to the conveying pipe 234, and the material conveyed by the screening unit 22 is received by the buffer bin 230.

[0037] The tungsten powder screened by the screening unit 22 is temporarily stored in the buffer bin 230, so that when the secondary output unit and the tertiary output unit are running alternately, the material screened by the screening unit 22 can have space to be temporarily stored. Even if the secondary output unit and the tertiary output unit temporarily stop operating, there will be no situation where the material has nowhere to be piled up.

[0038] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0039] Example 3:

[0040] This embodiment further expands the quantitative feeding unit 21 based on the above embodiment, specifically as follows: Figure 3 , Figure 4As shown, the quantitative feeding unit 21 includes a feed hopper 210, a primary output section, and a feed pipe 212. The feed hopper 210 is mounted on the feed pipe 212. The primary output section includes a primary output motor 211, whose output end is connected to a screw conveyor. The primary output motor 211 is mounted on the feed pipe 212. During operation, the primary output motor 211 drives the screw conveyor to push the tungsten powder fed into the feed hopper 210, conveying it from one end of the feed pipe 212 to the screening unit 22. The conveying speed of the primary output motor 211 depends on the screening speed of the screening unit 22. Since the screening efficiency of the screening unit 22 varies for different types of tungsten powder, the supply rate can be adjusted by changing the rotational speed of the primary output motor 211.

[0041] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0042] Example 4:

[0043] This embodiment further expands the screening unit 22 based on the above embodiment, specifically as follows: Figure 3 , Figure 4 As shown, the screening unit 22 includes a screening cylinder 220, a receiving cylinder 221, a collecting bucket 222, a material discharge pipe 223, a slag discharge pipe 224, and a first vibrating motor 225. The screening cylinder 220 is mounted on the receiving cylinder 221, and a screen is provided between the screening cylinder 220 and the receiving cylinder 221. The receiving cylinder 221 and the first vibrating motor 225 are both mounted on the mounting frame 10. The first vibrating motor 225 is connected to the receiving cylinder 221 in a driving connection. The receiving cylinder 221 is provided with a material discharge pipe 223, which discharges the material to the grading supply unit 23. The screening cylinder 220 is provided with a slag discharge pipe 224. The collecting bucket 222 is mounted on the mounting frame 10 and is used to receive the material discharged from the slag discharge pipe 224.

[0044] Since the receiving cylinder 221 and the support table 105 are connected by a spring, the screening cylinder 220 and the receiving cylinder 221 will start to vibrate when the first vibration motor 225 is started. When the tungsten powder enters the screening cylinder 220, the large particles of tungsten powder will be discharged into the collection bucket 222 through the slag discharge pipe 224, and can then be further crushed and ground for reuse. The small particles of tungsten powder that meet the standards will enter the receiving cylinder 221 through the screen, and then be discharged into the buffer bin 230 through the material discharge pipe 223.

[0045] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0046] Example 5:

[0047] This embodiment further expands upon the above embodiment by modifying the mounting bracket 10, specifically as follows: Figures 1-2 As shown, the mounting frame 10 includes support rods 101, a placement platform 102, a guardrail 103, a ladder 104, and a support table 105. Multiple support rods 101 are installed on the placement platform 102 to increase the height of the placement platform 102. The placement platform 102 is equipped with guardrails 103, ladders 104, and support table 105. The screening unit 22 is installed on the support table 105.

[0048] The support rod 101 is used to raise the entire feeding section 20 to accommodate the material receiving light operation of the subsequent work station; the guardrail 103 serves a protective function to prevent workers from falling during maintenance; the support table 105 further increases the height of the feeding section 20 and the quantitative feeding unit 21 to match the height of the graded supply unit 23.

[0049] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
