Description

A copper scrap collection device Technical Field

[0001] This utility model relates to the technical field of electrode cap processing equipment, specifically to a copper shavings collection device. Background Technology

[0002] In the processing of copper electrode caps, a specialized grinding device is used to grind the copper electrode caps, and a waste chip collection device is often used to collect the metal chips generated during grinding. Chinese invention patent CN111070037B discloses an integrated grinding and cap-changing device for electrode caps. It describes a chip removal device comprising a main body containing an interconnected vacuum generating chamber and a chip removal channel. The chip removal device also includes an L-shaped compressed air input pipe with its outlet facing the chip removal channel. When compressed air is input, a vacuum is generated in the vacuum generating chamber to draw the grinding chips into the chip removal channel for discharge. When grinding the electrode cap, a chip removal solenoid valve connected to the chip removal device circuit is activated, allowing compressed air to enter the compressed air input pipe. Due to the Venturi effect, a vacuum is generated in the vacuum generating chamber, drawing the grinding chips generated during grinding into a chip collection tank through the chip removal channel. The inventors discovered that while waste shavings collection devices utilizing the Venturi effect are widely used in electrode cap manufacturing equipment, compressed air can only be introduced into the internal environment through a single-direction inlet pipe, resulting in limited airflow. Furthermore, after prolonged use, the metal shavings adhering to the inner wall of the collection device require cleaning. Therefore, easy disassembly and assembly of the waste shavings collection device would significantly improve cleaning efficiency. There is an urgent need for a copper shavings collection device with good airflow and easy disassembly and assembly. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a copper shavings collection device with good airflow effect and convenient disassembly and assembly.

[0004] To solve the above-mentioned technical problems, the utility model includes a shell with a cavity for covering the grinding device. Its structural features are as follows: the shell is detachably connected to a vacuum seat, the vacuum seat has a first chamber that communicates with the cavity, and the vacuum seat is detachably connected to a vacuum cover located within the first chamber. The vacuum cover is hollow and open at both ends. The outer surface of the vacuum cover and the inner surface of the vacuum seat form a second chamber that is closed at one end and open at the other, with the open end communicating with the first chamber. The second chamber surrounds the outer surface of the vacuum cover. The shell has a connector through which external compressed air can enter the second chamber. The side of the vacuum seat away from the shell is piped to an external collection tank, and the open end of the second chamber faces the side of the vacuum seat away from the shell.

[0005] With the above structure, the second chamber guides the compressed air flowing in from the connector. After flowing in from the connector, the compressed air flows directionally through the second and first chambers to the external collection tank. This directional flow of compressed air creates a vacuum within the receiving chamber, thereby drawing copper shavings and other metal shavings generated during the grinding of electrode caps into the first chamber. The metal shavings ultimately reach the external collection tank. Because the second chamber surrounds the outer surface of the vacuum casing, it ensures that the compressed air flowing in from the connector is evenly and directionally dispersed into the first chamber, achieving multi-sided uniform air intake. Compared to pipe-based air intake methods like compressed air inlet pipes, this provides more uniform air intake and better airflow. Since the vacuum base is detachably connected to the outer shell and the vacuum casing is detachably connected to the vacuum base, convenient assembly and disassembly are possible. Disassembling the vacuum base and vacuum casing allows for convenient maintenance and cleaning, reducing maintenance and cleaning time and improving work efficiency.

[0006] Furthermore, the outer casing is provided with a slot, the vacuum seat is provided with a plug-in portion that can be inserted into the slot, and the outer casing is provided with a stop member that can abut against the plug-in portion inserted into the slot. By providing the slot and the plug-in portion, the vacuum seat can be detachably connected to the outer casing in a plug-in manner. By providing the stop member to abut against the plug-in portion, the plug-in portion can be tightly abutted against the slot after being subjected to the downward pressure of the stop member, preventing the plug-in portion from disengaging from the slot.

[0007] Furthermore, the vacuum base has a boss located within the first chamber, and the vacuum housing has a flange. The flange abuts against the end face of the boss near the outer shell, and the vacuum housing is inserted into the vacuum base via the inner side of the boss. By providing the boss, the vacuum housing can be detachably connected to the vacuum base in a plug-in manner. The boss and flange cooperate to position the vacuum housing on the vacuum base, and also prevent the vacuum housing from detaching from the vacuum base due to airflow within the first chamber.

[0008] Furthermore, a narrow cavity is provided at the junction of the open end of the second chamber and the first chamber, and the minimum cross-sectional area of ​​the narrow cavity is smaller than the cross-sectional area of ​​the second chamber. By providing the narrow cavity, the compressed air flowing into the second chamber can pass through the narrow cavity to increase its flow velocity before flowing into the first chamber, ensuring the flow effect of the compressed air and the suction effect of metal shavings.

[0009] Furthermore, the outer casing is equipped with an air supply component, which receives compressed air and agitates the metal shavings removed by the grinding device. By providing the air supply component, the compressed air flows into the receiving cavity through the air supply component, agitating the metal shavings removed by the grinding device, preventing the metal shavings from accumulating in the receiving cavity, and ensuring efficient suction of the metal shavings.

[0010] Furthermore, the outer casing includes a first housing, a second housing, and a supporting housing located between the first housing and the second housing. The first housing, the second housing, and the supporting housing are detachably connected by fasteners. The first housing and the second housing are each provided with clearance holes for avoiding the electrode cap. By setting up the first housing, the second housing, and the supporting housing, and by operating the fasteners, the first housing, the second housing, and the supporting housing can be easily disassembled and assembled, facilitating subsequent disassembly and maintenance.

[0011] Furthermore, the first and second housings are each equipped with an observation plate made of transparent material, and the clearance hole is located on the observation plate. By providing the observation plate, operators can observe the grinding process of the motor cap and the suction of metal shavings, making it convenient to use.

[0012] In summary, this utility model has the advantages of being easy to use and having a reasonable structure. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0024] Referring to Figures 1 to 8, this utility model includes a housing 1, which has a receiving cavity to cover the grinding device. The grinding device is a common component in the field of electrode cap processing equipment, and has been disclosed in Chinese invention patent (CN111070037B, entitled "An Integrated Grinding and Changing Device for Electrode Caps") and Chinese utility model patent (CN205129626U, entitled "An Electrode Grinding Waste Collection Device"). Its structural principle is well known to those skilled in the art and will not be described in detail here. The housing 1 includes a first shell 11, a second shell 12, and a supporting shell 13 located between the first shell 11 and the second shell 12. The first shell 11, the second shell 12, and the supporting shell 13 are detachably connected by fasteners. The cavity surrounded by the first shell 11, the second shell 12, and the supporting shell 13 forms the receiving cavity. Screws can be used as fasteners. The first shell 11 and the second shell 12 are respectively provided with clearance holes for avoiding the electrode cap. The first housing 11, the second housing 12, and the support housing 13 can be easily disassembled and assembled by operating fasteners, facilitating subsequent disassembly and maintenance. The first housing 11 and the second housing 12 are each equipped with an observation plate 100 made of transparent material, with clearance holes located on the observation plate 100. The observation plate 100 can be made of transparent plastic. By providing the observation plate 100, operators can observe the grinding process of the motor cap and the suction of metal shavings, making it convenient to use.

[0025] Referring to Figures 1 to 8, the outer casing 1 is detachably connected to a vacuum seat 2. The vacuum seat 2 has a first chamber 21 that communicates with the receiving cavity. Specifically, the outer casing 1 has a slot 6, and the vacuum seat 2 has a plug-in portion 22 that can be inserted into the slot 6. The outer casing 1 has an abutment 7 that abuts against the plug-in portion 22 inserted into the slot 6. The abutment 7 can be a hexagon socket head cap screw screwed onto the outer casing 1. The outer casing 1 and the vacuum seat 2 can also be detachably connected by threads. The outer casing 1 and the vacuum seat 2 have mutually mating threads. A sealing ring can be provided inside the outer casing 1 or the vacuum seat 2. The vacuum seat 2 is screwed onto the outer casing 1 and then sealed by the sealing ring. By setting the abutment 7 to abut against the plug-in portion 22, the plug-in portion 22 can be tightly pressed against the slot 6 under the downward pressure of the abutment 7, preventing the plug-in portion 22 from disengaging from the slot 6.

[0026] Referring to Figures 1 to 9, the vacuum base 2 is detachably connected to a vacuum housing 3 located within the first chamber 21. Specifically, the vacuum base 2 has a boss 23 located within the first chamber 21, and the vacuum housing 3 has a flange 31. The flange 31 abuts against the end face of the boss 23 near the outer shell 1. The vacuum housing 3 is inserted into the vacuum base 2 via the inner side of the boss 23. The vacuum housing 3 is hollow and open at both ends. The hollow interior of the vacuum housing 3 serves as a channel for the flow of metal shavings such as copper shavings. By providing the boss 23, the vacuum housing 3 can be detachably connected to the vacuum base 2 via an insertion method. The boss 23 and the flange 31 cooperate to position the vacuum housing 3 on the vacuum base 2, and the boss 23 and the flange 31 also prevent the vacuum housing 3 from detaching from the vacuum base 2 due to airflow within the first chamber 21. The outer surface of the vacuum casing 3 and the inner surface of the vacuum seat 2 form a second chamber 4, which is closed at one end and open at the other, with the open end connecting to the first chamber 21. The second chamber 4 surrounds the outer surface of the vacuum casing 3. The outer casing 1 is provided with a connector 5, through which external compressed air can enter the second chamber 4. The side of the vacuum seat 2 away from the outer casing 1 is connected to an external collection tank. The open end of the second chamber 4 faces the side of the vacuum seat 2 away from the outer casing 1, and the side of the vacuum seat 2 away from the outer casing 1 can be connected to the external collection tank via a telescopic pipe connected by a clamp. A narrow cavity 8 is provided at the junction of the open end of the second chamber 4 and the first chamber 21. The minimum cross-sectional area of ​​the narrow cavity 8 is smaller than the cross-sectional area of ​​the second chamber 4, and the narrow cavity 8 serves as the narrow outlet of the second chamber 4. By setting the narrow cavity 8, the compressed air flowing into the second chamber 4 can pass through the narrow cavity 8 to increase its flow velocity before flowing into the first chamber 21, ensuring the flow effect of the compressed air and the suction effect of metal shavings. The outer casing 1 is equipped with an air supply component 9, which receives compressed air and agitates the metal shavings removed by the grinding device. The air supply component 9 can be a universal elbow and an air pipe. The universal elbow is connected to the outer casing 1, one end of the air pipe is connected to the universal elbow, and the other end is located inside the receiving cavity. The end of the air pipe inside the receiving cavity faces the grinding device, and the universal elbow is connected to an external air source. By providing the air supply component 9, compressed air flows into the receiving cavity through it, agitating the metal shavings removed by the grinding device and preventing them from accumulating inside the cavity, thus ensuring efficient suction of the metal shavings. The blowing effect of the air supply component 9, combined with the vacuum effect provided by the vacuum casing 3 and the vacuum seat 2 to the receiving cavity, ensures efficient suction of the metal shavings.

[0027] When using this invention, refer to Figures 8 and 9. The arrows in Figure 8 indicate the direction of airflow. The second chamber 4 guides the compressed air flowing in from the connector 5. After flowing in from the connector 5, the compressed air flows directionally through the second chamber 4 and the first chamber 21 to the external collection tank. The directional flow of the compressed air creates a vacuum in the receiving chamber, thereby drawing copper shavings and other metal shavings generated during the grinding of the electrode cap by the grinding device into the first chamber 21. The metal shavings eventually reach the external collection tank. Because the second chamber 4 surrounds the outer surface of the vacuum casing 3, it allows the compressed air flowing in from the connector 5 to be evenly dispersed into the first chamber 21, achieving multi-sided uniform air intake. Compared to the pipe-type air intake method using a compressed air input pipe, this method offers more uniform air intake and better airflow. Since the vacuum base 2 is detachably connected to the outer shell 1 and the vacuum cover 3 is detachably connected to the vacuum base 2, convenient assembly and disassembly functions are realized. After disassembling the vacuum base 2 and the vacuum cover 3, convenient maintenance and cleaning operations can be performed, reducing the operation time of maintenance and cleaning operations and improving operation efficiency.
