Description
Technical Field
[0001] This invention relates to the field of coating machine technology, and in particular to a conductive structure for a gold-coated bronze furnace body of a metal decorative coating machine. Background Technology
[0002] In the hardware decoration industry, coating machines play a crucial role. They can form a special film layer on the surface of hardware products, which not only enhances the product's aesthetics but also improves its wear resistance, corrosion resistance, and other properties, thereby greatly increasing the product's added value. Imitation gold-coated metal, with its realistic gold appearance, is often used in various decorative hardware products, such as door handles, bathroom accessories, and lighting fixtures, meeting the market's demand for aesthetically pleasing and cost-effective decoration. The conductive structure, as a key component of the imitation gold-coated metal furnace body, directly affects the working efficiency and coating quality of the coating machine. Its working principle is to rotate the workpiece in a magnetic field by a rotating frame, while simultaneously introducing current into the workpiece through the conductive structure. Through the adsorption of positive and negative charges, the coating material with opposite charges adheres to the workpiece surface. However, existing conductive structures for imitation gold-coated metal furnace bodies generally have some significant problems.
[0003] In terms of energy consumption, the traditional conductive structure transmits current to the entire inner wall of the coating machine furnace, resulting in a large resistance during the current transmission process. This causes a large amount of electrical energy to be consumed as heat during transmission, which not only increases the production and operation costs of enterprises, but also does not conform to the current advocacy of energy conservation and emission reduction. Therefore, it is urgent to innovate and improve the conductive structure of the imitation gold-coated bronze furnace body in order to achieve the goals of energy saving and uniform coating, and improve the production level and economic benefits of the entire hardware decorative coating industry. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of existing technologies by proposing a conductive structure for the imitation gold-coated bronze furnace body of a hardware decorative coating machine. This invention, through the setting of guide rods, allows the device to switch the circuit distribution simultaneously during the initial operation and the coating stage. During initial operation, a concentrated current is used for preheating; during the coating stage, the current is evenly distributed to stabilize the magnetic field. Compared to existing technologies that transmit current to the entire inner wall of the coating machine's furnace, resulting in a large amount of electrical energy being consumed as heat during transmission, this device can reduce energy consumption while ensuring coating effect, thereby simultaneously improving the enterprise's production level and economic benefits.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a conductive structure for a gold-coated bronze furnace body of a metal decorative coating machine, comprising a rotating frame rotatably inserted into the furnace body of the coating machine and a furnace body central shaft cap fixed on the coating machine housing. Several equidistantly distributed circumferential hanging rods are rotatably inserted into the top outer wall of the rotating frame. Several bias-insulated connecting posts electrically connected to the hanging rods are provided on the outer wall of the rotating frame. A bias-connecting shaft for connecting to a power source is provided at the center of the outer wall of the rotating frame. A fixed shaft coaxial with the bias-connecting shaft is fixed at the center of the inner wall of the furnace body central shaft cap. An insulating block capable of vertical movement is slidably fitted onto the outer wall of the fixed shaft. A copper busbar for conducting electricity is provided at the bottom end of a displacement center riser on the outer wall of the rotating frame. Several equidistantly distributed circumferentially distributed insulating guide rails are provided on the outer wall of the copper busbar, and each insulating guide rail extends toward the bias-insulated connecting post. A conductive slider capable of electrically abutting the bias-insulated connecting post is slidably inserted into each insulating guide rail.
[0006] Preferably, a conductive mounting frame is provided on the outer wall of the insulating block, and a guide rod is rotatably connected to the outer wall of each conductive slider, with the end of each guide rod away from the conductive slider rotatably connected to the outer wall of the conductive mounting frame.
[0007] Preferably, the outer wall of the fixed shaft is provided with a first smooth rod section, a threaded section, a second smooth rod section and a boss in sequence from top to bottom, and the insulating block is fitted onto the outer wall of the threaded section by threaded engagement.
[0008] Preferably, a spring is provided between the outer wall of the insulating block and the outer wall of the boss, and the spring is fitted onto the outer wall of the fixed shaft.
[0009] Preferably, the copper busbar abuts against the bias connection shaft, and a copper column is provided on the outer wall of the copper busbar, the copper column being slidably inserted into the outer wall of the conductive mounting bracket.
[0010] Preferably, each of the hanging rods has a conductive bearing plate fitted on its bottom outer wall, each conductive bearing plate is fixed to the outer wall of the rotating frame, and each conductive bearing plate is electrically connected to the bias-insulated connecting post through a wire.
[0011] Preferably, a central vertical pipe is provided at the center of the outer wall of the rotating frame, and an anti-sway ring fixing plate is provided on the top outer wall of the central vertical pipe. The anti-sway ring fixing plate is rotatably inserted into the central shaft cap of the furnace body. Several equidistant circularly distributed clearance grooves are provided on the outer wall of the central vertical pipe, and the guide rod passes through the clearance grooves. A shielding cover located above the clearance grooves is provided on the outer wall of the rotating frame.
[0012] Preferably, the bottom end of the bias connecting shaft abuts against the conductive carbon brush, and a gear disc driven by a motor is fixed on the bottom outer wall of the rotating frame.
[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention, through the setting of the guide rod, enables the device to switch the circuit distribution simultaneously at the initial stage of equipment operation and during the coating stage. During initial operation, the current is concentrated for preheating, and during the coating stage, the current is evenly distributed to stabilize the magnetic field. Compared with the existing technology that transmits current to the entire inner wall of the coating machine, resulting in a large amount of electrical energy being consumed as heat during transmission, this device can reduce energy consumption while ensuring the coating effect, thereby improving the production level and economic benefits of enterprises at the same time.
[0014] 2. The present invention uses conductive sliders and insulated guide rails to arrange the guide rods in a circular pattern along the radius of the rotating frame. This makes the magnetic field distribution formed by the current in the furnace more uniform when the current passes through the guide rods, further improving the coating effect. In addition, the same length of each guide rod ensures that the current path of each branch is consistent, the voltage of each hanger rod is uniformly conducted, and the current is stable, further improving the coating effect.
[0015] 3. This invention, through the setting of a fixed shaft, allows the rotating frame to continue reversing when the insulating block returns to the threaded section, causing the insulating block to move to the first smooth rod section. At this time, the insulating block drives the conductive mounting bracket to disengage from the copper column on the copper busbar, thereby cutting off the current from the copper busbar. The current is then intercepted on the copper busbar at the central riser, resulting in no current flow inside the furnace, facilitating the removal of the coated workpiece. Compared to existing technologies that require the device to be powered off before material removal, this device achieves material removal without shutting off the equipment power supply by cutting off the circuit, thereby reducing the frequency of power on / off and thus reducing the additional energy consumption caused by the power on / off process. Especially in mass production operations, keeping the equipment powered on during material removal allows for immediate operation after loading, shortening equipment preparation time and greatly improving work efficiency.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0019] See Figures 1 to 8 As shown, a conductive structure for a gold-coated bronze furnace body of a metal decorative coating machine includes a rotating frame 1 rotatably inserted into the furnace body of the coating machine and a furnace body central shaft cap 15 fixed to the shell of the coating machine. Several equidistantly distributed hanging rods 11 are rotatably inserted into the top outer wall of the rotating frame 1. Several bias-insulated connecting posts 112 electrically connected to the hanging rods 11 are provided on the outer wall of the rotating frame 1. A bias-connecting shaft 121 for connecting to a power source is provided at the center of the outer wall of the rotating frame 1. A conductive bearing plate 111 is fitted onto the bottom outer wall of each hanging rod 11, and each conductive bearing plate 111 is fixed to the outer wall of the rotating frame 1. All 111 are electrically connected to the bias-insulated connecting post 112 via wires. A central riser 14 is provided at the center of the outer wall of the rotating frame 1. An anti-sway ring fixing plate 141 is provided on the top outer wall of the central riser 14. The anti-sway ring fixing plate 141 is rotatably inserted into the central shaft cap 15 of the furnace body. Several equidistant circularly distributed clearance grooves 142 are provided on the outer wall of the central riser 14. The guide rod 33 passes through the clearance grooves 142. A shielding cover 13 is provided on the outer wall of the rotating frame 1 above the clearance grooves 142. The bottom end of the bias-connecting shaft 121 abuts against the conductive carbon brush. A gear disc 12 driven by a motor is fixed on the bottom outer wall of the rotating frame 1.
[0020] It should be noted that by supplying a bias current to each hanger rod 11, the workpiece and the coating material are respectively charged with opposite charges. Under the effect of charge adsorption, the coating material impacts and adheres to the surface of the workpiece, thus achieving the coating effect. Furthermore, by energizing the equidistantly distributed hanger rods 11, the magnetic field distribution inside the coating machine furnace is made more uniform, thereby improving the coating effect.
[0021] A fixed shaft 151, coaxially distributed with the bias connection shaft 121, is fixed at the center of the inner wall of the furnace body central shaft cap 15. An insulating block 3, capable of moving up and down, is slidably fitted on the outer wall of the fixed shaft 151. A copper busbar 2 for conducting electricity is provided at the bottom end of the displacement center riser 14 on the outer wall of the rotating frame 1. Several equidistantly distributed insulating guide rails 22 are provided on the outer wall of the copper busbar 2, and each insulating guide rail 22 extends toward the bias insulating connection post 112. A conductive slider 34, capable of electrically contacting the bias insulating connection post 112, is slidably inserted into each insulating guide rail 22. A conductive mounting bracket 32 is provided on the outer wall of the insulating block 3. Each conductive slider 34 has an outer... Guide rods 33 are rotatably connected to the wall. The end of each guide rod 33 away from the conductive slider 34 is rotatably connected to the outer wall of the conductive mounting frame 32. The outer wall of the fixed shaft 151 is provided with a first smooth rod section 153, a threaded section 152, a second smooth rod section 154 and a boss 155 from top to bottom. The insulating block 3 is fitted onto the outer wall of the threaded section 152 by threaded engagement. A spring 31 is provided between the outer wall of the insulating block 3 and the outer wall of the boss 155. The spring 31 is fitted onto the outer wall of the fixed shaft 151. The copper busbar 2 abuts against the bias connection shaft 121. A copper column 21 is provided on the outer wall of the copper busbar 2. The copper column 21 is slidably inserted into the outer wall of the conductive mounting frame 32.
[0022] It should be noted that in the initial state, the insulating block 3 is located at one end of the threaded section 152 near the first smooth rod section 153, the spring 31 is in a stretched state, and the conductive mounting bracket 32 pulls the conductive slider 34 to move to the side near the central riser 14 through the guide rod 33. At this time, the conductive slider 34 is disconnected from the bias insulating connecting post 112, the hanging rod 11 is not energized, and all the guide rods 33 are concentrated at the position of the central riser 14. Thus, when the coating machine is energized, the current is conducted sequentially through the carbon brush along the bias connecting shaft 121, copper busbar 2, conductive mounting bracket 32, guide rod 33 and conductive slider 34, thereby concentrating the current at the central conductor. The concentrated current accelerates preheating, thereby shortening the overall working time of the equipment and achieving the effect of reducing energy consumption.
[0023] During the coating stage, the gear disc 12 driven by the external motor drives the rotating frame 1 to rotate. The rotating frame 1 drives the insulating block 3 to rotate relative to the fixed shaft 151. Under the action of the threaded engagement, the insulating block 3 drives the conductive mounting frame 32 to move downward. This causes the conductive mounting frame 32 to push the conductive slider 34 to abut against the biased insulating connecting post 112 through the guide rod 33. This energizes the hanger rod 11, thereby changing the circuit distribution during operation and distributing the current evenly. This not only ensures the uniformity of the coating effect but also greatly improves the current utilization rate, avoiding the excessive concentration of current that would cause electrical energy to be consumed as heat.
[0024] Meanwhile, under the action of the conductive slider 34 and the insulating guide rail 22, the guide rods 33 are arranged in a circular pattern along the radius of the rotating frame 1, so that when the current passes through the guide rods 33, the magnetic field distribution formed by the current in the furnace body is more uniform, which further improves the coating effect. In addition, the length of each guide rod 33 is the same, so that the path current of each branch is consistent, thereby making the voltage of each hanger rod 11 uniformly conducted and the current stable, which further improves the coating effect.
[0025] In summary, compared to existing technologies that transmit current to the entire inner wall of the coating machine, resulting in a large amount of electrical energy being consumed as heat during transmission, this device switches the circuit distribution simultaneously at the initial stage and during the coating stage. During initial operation, the current is concentrated for preheating, and during the coating stage, the current is evenly distributed to stabilize the magnetic field, reducing energy consumption while ensuring coating effect, thereby improving the production level and economic benefits of enterprises.
[0026] In addition, when the conductive slider 34 abuts against the biased insulating connecting post 112, the insulating block 3 moves onto the second smooth rod section 154. At this time, the spring 31 is in a compressed state. After the coating is completed, the motor drives the gear disc 12 to drive the rotating frame 1 to rotate in the opposite direction. At this time, under the action of the spring 31, the insulating block 3 engages with the threaded section 152 again. As the insulating block 3 drives the conductive mounting frame 32 to move upward, the conductive mounting frame 32 pulls the guide rod 33. At this time, the guide rod 33 is subjected to tension, thereby correcting the straightness of the guide rod 33 to a certain extent, reducing the bending deformation of the guide rod 33 during long-term operation, and thus improving the service life of the device.
[0027] Furthermore, when the insulating block 3 returns to the threaded section 152, it continues to drive the rotating frame 1 to reverse, causing the insulating block 3 to move onto the first smooth rod section 153. At this time, the insulating block 3 drives the conductive mounting frame 32 to disengage from the copper column 21 on the copper busbar 2, thereby cutting off the current from the copper busbar 2. The current is then intercepted on the copper busbar 2 at the central riser 14, resulting in no current flow inside the furnace, which facilitates the removal of the coated workpiece. Compared with the prior art, which requires the device to be powered off before material can be removed, this device achieves material removal without turning off the power supply by cutting off the circuit, thereby reducing the frequency of power on / off and thus reducing the additional energy consumption caused by the power on / off process. Especially in mass production operations, keeping the equipment powered on during material removal allows for immediate operation after loading, shortening equipment preparation time and greatly improving work efficiency.
[0028] Working principle: In the initial state, the insulating block 3 is located at one end of the threaded section 152 near the first smooth rod section 153, the spring 31 is in a stretched state, and the conductive mounting bracket 32 pulls the conductive slider 34 to move to the side near the central riser 14 through the guide rod 33. At this time, the conductive slider 34 is disconnected from the bias insulating connecting post 112, the hanger rod 11 is not energized, and all the guide rods 33 are concentrated at the position of the central riser 14. Thus, when the coating machine is energized, the current is conducted sequentially through the carbon brush along the bias connecting shaft 121, copper busbar 2, conductive mounting bracket 32, guide rod 33 and conductive slider 34, thereby concentrating the current at the central conductor. The concentrated current accelerates preheating, thereby shortening the overall working time of the equipment and achieving the effect of reducing energy consumption. During the coating stage, the gear disc 12 driven by the external motor drives the rotating frame 1 to rotate. The rotating frame 1 drives the insulating block 3 to rotate relative to the fixed shaft 151. Under the action of the threaded engagement, the insulating block 3 drives the conductive mounting frame 32 to move down. This causes the conductive mounting frame 32 to push the conductive slider 34 to abut against the biased insulating connecting post 112 through the guide rod 33. This energizes the hanger rod 11, thereby changing the circuit distribution during operation and distributing the current evenly. This not only ensures the uniformity of the coating effect but also greatly improves the current utilization rate, avoiding the loss of electrical energy as heat due to excessive current concentration. Meanwhile, under the action of the conductive slider 34 and the insulating guide rail 22, the guide rods 33 are arranged in a circular pattern along the radius of the rotating frame 1, so that when the current passes through the guide rods 33, the magnetic field distribution formed by the current in the furnace is more uniform, which further improves the coating effect. In addition, the length of each guide rod 33 is the same, so that the current path of each branch is consistent, the voltage of each hanger rod 11 is uniformly conducted, the current is stable, which further improves the coating effect. Furthermore, when the insulating block 3 returns to the threaded section 152, it continues to drive the rotating frame 1 to reverse, causing the insulating block 3 to move onto the first smooth rod section 153. At this time, the insulating block 3 drives the conductive mounting frame 32 to disengage from the copper column 21 on the copper busbar 2, thereby cutting off the current from the copper busbar 2. The current is then intercepted on the copper busbar 2 at the central riser 14, resulting in no current flow inside the furnace, which facilitates the removal of the coated workpiece. Compared with the prior art, which requires the device to be powered off before material can be removed, this device achieves material removal without turning off the power supply by cutting off the circuit, thereby reducing the frequency of power on / off and thus reducing the additional energy consumption caused by the power on / off process. Especially in mass production operations, keeping the equipment powered on during material removal allows for immediate operation after loading, shortening equipment preparation time and greatly improving work efficiency.
