Description

Technical Field

[0001] This utility model relates to the field of powder equipment technology, and in particular to a scraping device. Background Technology

[0002] In industrial production, the processing of fine powdery materials is a common step. For example, in the production of electronic materials, powder metallurgy, and feed, it is necessary to precisely fill fine powdery materials into specific containers. Currently, the common filling method involves using a feeding auger to transport the powdery material into a rectangular crucible. During this process, a vacuum device is usually activated to ensure the material is compacted. However, this filling method has a significant problem: when the pressure head at the bottom of the feeding auger is lifted after pressing down, clumps of material form at the bottom of the pressure head because the vacuum device remains on. These clumps are difficult to clean, and once the crucible is removed, the material scatters onto the ground. This not only wastes material and increases production costs but also pollutes the production environment, affecting the hygiene of the production workshop and potentially adversely impacting subsequent production processes.

[0003] Therefore, developing a device that can effectively clean up clumps of material at the bottom of the pressing head is of great practical significance. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the shortcomings of the existing technology, this utility model provides a scraping device that can solve the problem that the bottom clump of material cannot be cleaned when the pressing head is raised, resulting in material scattering, waste and environmental pollution.

[0005] Technical solution: Scraping device, including:

[0006] Mounting plate, used to connect and secure to the feeding auger;

[0007] The drive mechanism is fixed to the mounting plate;

[0008] A flexible traction component assembly connected to the drive mechanism is included, comprising at least one flexible traction component, for reciprocating motion under the action of the drive mechanism.

[0009] A scraper, mounted on the flexible traction member, is used to scrape off the material remaining on the pressing head;

[0010] An elastic reset mechanism is disposed in the transmission path of the flexible traction member;

[0011] The drive mechanism drives the scraper to reciprocate through a flexible traction member, and the elastic reset mechanism keeps the flexible traction member in a tensioned state.

[0012] Furthermore, it also includes:

[0013] A pulley block is disposed above the mounting plate, and the flexible traction member is wound around the pulley block to form a transmission circuit.

[0014] Furthermore, the driving mechanism is a linear actuator, and the end of the driving mechanism is provided with a lower connecting plate for connecting the first end of the flexible traction member. The lower connecting plate and the mounting plate are also slidably connected by a guide post.

[0015] Furthermore, the elastic reset mechanism includes:

[0016] A mounting base is disposed above the mounting plate, and the mounting base is used to connect to the second end of the flexible traction member;

[0017] An elastic element disposed between the mounting plate and the mounting base.

[0018] Furthermore, the flexible traction member is provided with a pre-tension adjustment assembly.

[0019] Furthermore, the pretension adjustment component is a turnbuckle.

[0020] Furthermore, it also includes a pulley lower pressure plate disposed at the bottom of the pressure head, and the flexible traction member is wound around the bottom side of the pulley lower pressure plate.

[0021] Furthermore, each group of the flexible traction components includes two flexible traction components, which are arranged in parallel at both ends of the scraper plate.

[0022] Furthermore, there are two flexible traction component groups, which are arranged opposite to each other on both sides of the mounting plate, and correspondingly there are also two scraper plates, which are respectively arranged on the two flexible traction component groups.

[0023] Beneficial effects: After the material pressing head completes the compaction operation, the drive mechanism drives the scraper plate to slide through the flexible traction component group to scrape off the residual material at the bottom of the material pressing head. The flexible traction component is kept taut by the elastic reset mechanism to avoid slack error and prevent the clumps of material from being unable to be cleaned and causing the material to fall to the ground and cause pollution after the crucible is removed. Moreover, the structure is relatively simple and easy to manufacture and promote. Attached Figure Description

[0029] See Figure 1-2 An embodiment of the scraping device of this utility model is shown, comprising: a mounting plate 10, a drive mechanism 8, a flexible traction component assembly, a scraper plate 15, and an elastic reset mechanism. The mounting plate 10 is used to connect and fix to the feeding auger 1, and can be made of rectangular steel plate with mounting holes at its four corners. It is fixedly connected to the frame of the feeding auger 1 by high-strength bolts. The bottom of the feeding auger 1 is provided with a pressing head 3, and the pressing head 3 is provided with an air extraction port 2. The feeding auger 1 is used to convey powdered material 5 into the crucible or other container below, and relies on the air extraction port 2 to evacuate and compact it. After being filled into the container, it is pressed and compacted by the pressing head 3.

[0030] The drive mechanism 8 is fixed to the mounting plate 10, and preferably employs a linear actuator such as a cylinder assembly or a hydraulic cylinder assembly. A flexible traction component assembly is driven and connected to the drive mechanism 8, including at least one flexible traction component 9, for reciprocating motion under the action of the drive mechanism 8. Specifically, the flexible traction component 9 is a steel wire rope, but it can also be a polymer rope such as polyester rope, nylon rope, or a polyester-nylon blended rope.

[0031] A scraper 15 is mounted on the flexible traction member 9 to scrape off residual material from the pressing head 3. The working surface of the scraper 15 matches the curvature of the bottom surface of the pressing head 3. The middle or both sides of the scraper are rigidly connected to the connection point. An elastic reset mechanism is located in the transmission path of the flexible traction member 9. The drive mechanism 8 drives the scraper to reciprocate through the flexible traction member 9, and the elastic reset mechanism keeps the flexible traction member 9 in a tensioned state.

[0032] After the pressing head 3 completes the compaction operation, the drive mechanism 8 drives the scraper 15 to slide through the flexible traction component group to scrape off the residual material at the bottom of the pressing head 3. The flexible traction component 9 is kept taut by the elastic reset mechanism to avoid slack error and to prevent the clumps of material from being unable to be cleaned and causing the material to fall to the ground and cause pollution after the crucible is removed. Moreover, the structure is relatively simple and easy to manufacture and promote.

[0033] It also includes a pulley block 7 disposed above the mounting plate 10, and the flexible traction member 9 is wound around the pulley block 7 to form a transmission circuit to assist in saving effort and reduce the resistance encountered by the scraper plate 15 when scraping material.

[0034] The drive mechanism 8 has a lower connecting plate 13 at its end for connecting the first end of the flexible traction member 9. The lower connecting plate 13 and the mounting plate 10 are also slidably connected by a guide post 12. The elastic reset mechanism includes a mounting base and an elastic element 11. The mounting base is disposed above the mounting plate 10 and is used to connect to the second end of the flexible traction member 9, thereby enabling the flexible traction member 9 to form a closed loop. The elastic element 11 is disposed between the mounting plate 10 and the mounting base, thereby tightening the flexible traction member 9.

[0035] In some preferred embodiments, the flexible traction member 9 is provided with a pretension adjustment component 14. Specifically, the pretension adjustment component 14 is a turnbuckle, which has a relatively simple structure and can easily adjust the pretension of the flexible traction member 9.

[0036] In some preferred embodiments, a pulley lower pressure plate 4 is further provided at the bottom of the pressure head 3, and the flexible traction member 9 is wound around the bottom side of the pulley lower pressure plate 4. Pulleys are provided at both ends of the pulley lower pressure plate 4 to assist in guiding the movement of the flexible traction member 9.

[0037] In this embodiment, each set of flexible traction components includes two flexible traction components 9, which are arranged parallel to each other at the horizontal ends of the scraper plate 15. There are two sets of flexible traction components, arranged opposite each other on both sides of the mounting plate 10. Correspondingly, there are also two scraper plates 15, each mounted on one of the two sets of flexible traction components. Thus, a single drive mechanism 8 can be used simultaneously to scrape material from both pressure heads 3, greatly improving work efficiency.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
