Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of feeding auxiliary equipment, and in particular to a feeding device for modifying copper-gold powder materials. Background Technology
[0002] A powder modification machine is a device specifically designed for the physical or chemical modification of the surface of powder materials. By altering the surface properties of powder particles (such as surface energy, wettability, dispersibility, and adsorption), it can meet the needs of specific industrial applications.
[0003] The existing powder modification machines mostly feed different raw materials into the feeding hopper according to a certain ratio. Most of the feeding hoppers have an open design, that is, the top is open, which makes it convenient to manually pour the weighed raw materials and auxiliary materials into it and then mix them.
[0004] However, there is a certain height difference between the feeding hopper and the ground, which requires workers to lift the materials to the feeding hopper and then pour them in. This not only reduces work efficiency but also increases the workload of workers. In addition, the pouring process will cause dust to spill out, resulting in environmental pollution in the workshop. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides a feeding device for modifying copper-gold powder materials.
[0006] The technical solution of this utility model is achieved through the following scheme: a feeding device for modifying copper-gold powder material, including a modifying machine, a negative pressure pneumatic conveying device and a feeding device, wherein the feeding device is obliquely supported on the modifying machine by a support frame, the feeding device is connected to the modifying machine through the negative pressure pneumatic conveying device, and the feeding port of the feeding device is opened at the lowest end of the feeding device.
[0007] The feeding device includes a copper-gold powder feeding system and an auxiliary material feeding system. The auxiliary material feeding system is mounted on the copper-gold powder feeding system. The copper-gold powder feeding system is flange-connected to the auxiliary material feeding system. Both the copper-gold powder feeding system and the auxiliary material feeding system are connected to the modifier through a negative pressure pneumatic conveying device.
[0008] Through the above technical solutions, the sleeve-type dual system integration achieves precise collaborative feeding and independent material conveying; the negative pressure pneumatic conveying equipment realizes the final conveying of copper gold powder and auxiliary materials, and the inclined low-opening design reduces labor intensity and safety hazards, reduces the risk of muscle strain caused by repetitive high-intensity movements, and reduces the probability of material spillage, effectively preventing the leakage of auxiliary material dust.
[0009] Preferably, the copper-gold powder feeding system includes a feeding inner cylinder, a spiral conveying roller, a feeding hopper, and a drive motor. The spiral conveying roller is rotatably installed in the feeding inner cylinder, and the drive end of the drive motor is connected to the spiral conveying roller.

[0011] Preferably, the drive motor is installed at the lowest end of the feed cylinder away from the modifyer, and the feeding hopper is located on the outer wall of the feed cylinder near the drive motor.
[0012] Through the above technical solutions, the rotary thrust combined with the negative pressure pneumatic conveying equipment continuously and stably conveys the copper-gold powder into the modifier, ensuring that the copper-gold powder enters the modifier at a uniform flow rate and avoiding material accumulation or interruption. The inner feed cylinder provides a sealed conveying space for the copper-gold powder, preventing the copper-gold powder from flying and leaking during the conveying process and reducing material loss. The relatively low position of the feeding hopper reduces vibration and noise during operation, while also facilitating the feeding operation for the operator.
[0013] Preferably, the auxiliary material feeding system includes an outer feeding cylinder, which is divided into a left chamber and a right chamber by a partition. The right chamber is connected to a first feeding pipe, the left chamber is connected to a second feeding pipe, and the outer feeding cylinder is connected to...
[0014] Preferably, the partition plate abuts against the inner feed cylinder.
[0015] Preferably, the negative pressure pneumatic conveying equipment connects the outer feed cylinder and the inner feed cylinder through a negative pressure feeding chamber.
[0016] Through the above technical solutions, the left and right chambers enable precise classification and conveying of auxiliary materials, meeting the requirements of copper-gold powder modification for different proportions and addition sequences of various auxiliary materials, thereby improving product quality and performance stability, and effectively preventing mixing and cross-contamination between different auxiliary materials; the rapid suction of negative pressure in the negative pressure feeding chamber shortens the feeding time and improves production efficiency.
[0017] In summary, this utility model has the following beneficial effects:
[0018] 1. This utility model achieves precise and coordinated feeding and independent material conveying through the sleeve-type dual system integration; the negative pressure pneumatic conveying equipment realizes the final conveying of copper gold powder and auxiliary materials, and the inclined low-opening design reduces labor intensity and safety hazards, reduces the risk of muscle strain caused by repetitive high-intensity movements, and reduces the probability of material spillage, effectively preventing the leakage of auxiliary material dust.

[0029] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. The present invention will be further described in detail below with reference to the accompanying drawings.
[0031] A feeding device for modifying copper-gold powder materials, such as Figures 1-6 As shown, the system includes a modifier 100, a negative pressure pneumatic conveying device 101, and a feeding device 2. The feeding device 2 is supported by a support frame 1, which is inclined on the modifier 100. The support frame 1 is fixedly installed on the modifier 100 in a stepped manner. The feeding device 2 is connected to the modifier 100 through the negative pressure pneumatic conveying device 101. The feeding port of the feeding device 2 is located at the lowest end of the feeding device 2, transporting the powder from bottom to top. The workers only need to put the powder into the feeding port at a lower position, without having to lift the material, thus reducing the labor intensity of the workers. Under negative pressure, the material is stably transported in the pipeline. The auxiliary material feeding system 4 is connected to the modifier 100 through the pneumatic conveying device.
[0032] The feeding device 2 includes a copper-gold powder feeding system 3 and an auxiliary material feeding system 4. The auxiliary material feeding system 4 is mounted on the copper-gold powder feeding system 3. The copper-gold powder feeding system 3 is flanged and connected to the auxiliary material feeding system 4. The two systems are mounted together and fixed and sealed by the flange. The copper-gold powder and auxiliary materials can be fed separately without interfering with each other. The feeding sequence, feeding time and feeding amount of the copper-gold powder and auxiliary materials can be flexibly adjusted. The reliable sealing performance prevents cross-contamination. Both the copper-gold powder feeding system 3 and the auxiliary material feeding system 4 are connected to the modifier 100 through the negative pressure pneumatic conveying equipment 101.
[0033] like Figure 3 and Figure 4 As shown, the copper-gold powder feeding system 3 includes a feeding inner cylinder 31, a spiral conveying roller 32, a feeding hopper 33, and a drive motor 34. The spiral conveying roller 32 is rotatably installed in the feeding inner cylinder 31. The feeding inner cylinder 31 has through holes adapted to the spiral conveying roller 32. The drive end of the drive motor 34 is connected to the spiral conveying roller 32. The feeding hopper 33 is provided on the feeding inner cylinder 31, forming an auger screw conveyor. When the copper-gold powder enters the feeding inner cylinder 31 from the feeding hopper 33, the spiral blades of the spiral conveying roller 32 will continuously push the copper-gold powder forward. Due to the continuity and regularity of the spiral blades, the copper-gold powder can be conveyed at a relatively uniform speed and flow rate, avoiding blockage, interruption, or backflow of materials during the conveying process, thereby ensuring the high efficiency and stability of feeding. The drive motor 34 is preferably a servo motor, which can effectively prevent auxiliary materials from flowing back into the feeding inner cylinder 31.
[0034] The inner feed cylinder 31 is flanged and connected to the auxiliary material feeding system 4. The outer wall of the inner feed cylinder 31 is provided with a flange. Most of the inner feed cylinder 31 is inserted into the outer feed cylinder 41 of the auxiliary material feeding system 4. When the screw conveyor roller 32 rotates to convey copper gold powder, the inner feed cylinder 31 will be subjected to a certain force. The design of most of it being inserted can enable the inner feed cylinder 31 to better bear the stress, reduce shaking and displacement, and ensure the normal operation of the screw conveyor roller 32 and the stability of material conveying. A small part is exposed, and the feeding hopper 33 is installed on the exposed part of the inner feed cylinder 31.
[0035] The nested design saves space in the overall equipment. During the installation process, the inner feed cylinder 31 is simply inserted into the outer feed cylinder 41 of the auxiliary material feeding system 4 and then fixed by sealing with flange bolts. When the equipment needs maintenance or repair, the flange connection also facilitates quick disassembly of the inner feed cylinder 31, making it convenient to inspect, clean and repair the inside of the inner feed cylinder 31 and other components such as the screw conveyor roller 32.
[0036] The drive motor 34 is installed at the lowest end of the feed inner cylinder 31, away from the modifyer 100. The feeding hopper 33 is located on the outer wall of the feed inner cylinder 31, close to the drive motor 34. The equipment is in a relatively low and easily accessible position, so the workers do not need to climb or move to a higher or more complex position to pour the copper gold powder into the feeding hopper 33, which reduces the labor intensity and safety risks during the feeding process.
[0037] When the drive motor 34 is working, it will generate a certain amount of vibration and heat. The feeding hopper 33 is close to the drive motor 34. To a certain extent, the vibration of the motor during operation can be used to promote the smooth falling of copper gold powder into the inner feeding cylinder 31, and prevent the material from accumulating in the feeding hopper 33. At the same time, the reasonable distance setting can also use the heat of the motor to dry the material in the feeding hopper 33, ensuring the stable drying quality of the copper gold powder.
[0038] like Figure 4 , Figure 5 and Figure 6 As shown, the auxiliary material feeding system 4 includes an outer feeding cylinder 41, which is divided into a left chamber 42 and a right chamber 43 by a partition 5. The right chamber 43 is connected to the first feeding pipe 44, and the left chamber 42 is connected to the second feeding pipe 45. The outer feeding cylinder 41 is connected to the first feeding pipe 44. One end of the outer feeding cylinder 41 has a threaded groove that matches the flange of the inner feeding cylinder 31, and the other end is connected to the negative pressure feeding chamber 6. The partition 5 abuts against the inner feeding cylinder 31 and matches the arc surface of the inner feeding cylinder 31. After the inner feeding cylinder 31 is inserted, it naturally and tightly fits the arc surface of the partition 5 to form two feeding chambers. Both the first feeding pipe 44 and the second feeding pipe 45 can be connected to external pipelines and connected to the auxiliary material storage box for negative pressure suction. This ensures that the auxiliary materials in the left chamber 42 and the right chamber 43 will not leak into each other during the negative pressure suction and material conveying process, thus ensuring the independence of each auxiliary material.
[0039] The auxiliary material feeding system 4 can simultaneously process two different types of auxiliary materials, and can independently store and control the conveying of the two auxiliary materials. In actual powder modification production, it is often necessary to add multiple auxiliary materials to improve the performance of the product (for example, one auxiliary material may be a dispersant used to improve powder dispersibility, and another may be a grinding aid used to adjust the particle size of the powder). The left chamber 42 and the right chamber 43 can control the addition amount and addition time of each auxiliary material according to production needs to meet the requirements of different modification processes. The auxiliary materials enter the corresponding chambers of the feed cylinder 41 independently through their respective feeding pipes, avoiding cross-contamination between auxiliary materials and ensuring the purity and quality of each auxiliary material.
[0040] like Figure 1 and Figure 4 As shown, the negative pressure pneumatic conveying device 101 connects the outer feed cylinder 41 and the inner feed cylinder 31 through the negative pressure feeding chamber 6. The end of the inner feed cylinder 31 away from the drive motor 34 is connected to the negative pressure feeding chamber 6. When the negative pressure pneumatic conveying device 101 is working, the negative pressure feeding chamber 6 will generate a negative pressure environment. Under the action of this pressure difference, the material in the auxiliary material storage box connected to the outer feed cylinder 41 is quickly sucked up and enters the negative pressure feeding chamber 6 through the outer feed cylinder 41. Then it is conveyed to the modifier 100. Whether it is a powdery material with good flowability or a material with certain viscosity or easy agglomeration, the suction force generated by the negative pressure can overcome the resistance of the material and achieve stable conveying.
[0041] The negative pressure feeding chamber 6 is connected by flanges to the feed outer cylinder 41, the negative pressure pneumatic conveying equipment 101 and the modifier 100, thus becoming the final feeding chamber.
[0042] The excipients are modifiers or other auxiliary powders.
[0043] All parts and equipment use conventional models in the existing technology. In addition, the circuit connection and communication connection adopt conventional connection methods in the existing technology, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
[0044] Working principle: The operator connects the first feeding pipe 44 and the second feeding pipe 45 to the weighed and different auxiliary material storage boxes respectively (whether to connect both depends on the modification situation). Then, the negative pressure pneumatic conveying equipment 101 is started to perform negative pressure feeding. The copper gold powder feeding system 3 drive motor 34 is then started to make the spiral conveying roller 32 in the inner feeding cylinder 31 rotate. At this time, the copper gold powder raw material is poured into the feeding hopper 33 for batch feeding until it passes through the negative pressure discharge chamber 6 and is sucked into the modifier 100, where it is modified with the auxiliary materials.
[0045] 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 other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
