Technical Field

[0001] The utility model relates to the technical field of feeding mechanisms, in particular to a feeding mechanism for copper and gold powder coating production. Background Art

[0002] An automatic feeder for copper and gold powder production disclosed in Chinese patent CN217343569U is a kind of automatic feeder for copper and gold powder production. The automatic feeder for copper and gold powder production is conducive to fixing the inner wall of the top end of the shell body through the outer cylinder, and plays a good role in receiving the structure arranged on the inner side thereof. The inner cylinder can cooperate with the first through hole arranged at the bottom end of the body and the second through hole arranged at the bottom end of the outer cylinder, as well as the lower bucket and the feeding pipe under the driving rotation action of the motor, the rotating shaft and the connecting arm, to play an effective and relatively uniform and quantitative feeding effect on the copper and gold powder preparation raw materials accumulated in the inner cylinder, thereby realizing the overall automation and uniform and quantitative feeding effect of the copper and gold powder production equipment. However, the copper and gold powder is easy to oxidize. The automatic feeder for copper and gold powder production has the disadvantage that the copper and gold powder is easy to oxidize in contact with the air during feeding while solving the problem. Utility Model Content

[0003] In order to prevent the copper-gold powder from being easily oxidized during feeding, the utility model provides a feeding mechanism for copper-gold powder coating production.

[0004] The utility model provides a feeding mechanism for copper and gold powder coating production, which adopts the following technical scheme:

[0005] A feeding mechanism for copper-gold powder coating production comprises an electrical module and a mechanical module. The mechanical module comprises a silo and a vacuum pump. The top of the silo is fixedly connected to the input end of the vacuum pump, and a filter is fixedly connected to the interior of the silo. The electrical module comprises a control system.

[0006] By adopting the above technical solution, the control system operates the vacuum pump to start, so that negative pressure is formed in the silo to automatically load the copper and gold powder into the silo.

[0007] Preferably, an air vent pipe is provided on the outer surface of the silo, and an air vent valve is fixedly connected to the inside of the air vent pipe.

[0008] By adopting the above technical solution, when both the feed pipe and the discharge pipe are blocked by copper-gold powder, the vent pipe is used as a safeguard to avoid complete imbalance of air pressure inside and outside the silo.

[0009] Preferably, a discharge pipe is fixedly connected to the bottom of the silo, and a stopcock is fixedly connected to the outer surface of the discharge pipe.

[0010] By adopting the above technical solution, the copper-gold powder enters the production of the next coating process through the discharge pipe.

[0011] Preferably, a feed pipe is fixedly connected to the outer surface of the silo, and the other end of the feed pipe is fixedly connected to a raw material box.

[0012] By adopting the above technical solution, after negative pressure is formed in the silo, the copper-gold powder enters the interior of the raw material box through the feed pipe.

[0013] Preferably, the filter is located above the feed pipe.

[0014] By adopting the above technical solution, it is convenient to filter copper and gold powder, block the copper and gold powder from entering the interior of the vacuum pump, avoid wasting copper and gold powder, and prevent the use of the filter from being hindered.

[0015] Preferably, a back-blowing air bag is fixedly connected to the interior of the silo, and the vacuum pump, filter, stopcock and back-blowing air bag are all communicatively connected to a control system, and the back-blowing air bag is located between the filter and the vacuum pump.

[0016] By adopting the above technical solution, it is convenient for employees to control the opening and closing of various valves and electrical parts through the control program, so that the back-blowing air bag and the plug valve can be opened at the same time, avoiding the need for multiple employees to open the switches of different valves and machines at the same time, which wastes human resources.

[0017] As the technical solution of the utility model, the hardware setting provided is only for the purpose of facilitating the avoidance of the copper and gold powder from being easily oxidized when the copper and gold powder is loaded on the basis of hardware facilities. The specific method of avoiding the copper and gold powder from being easily oxidized when the copper and gold powder is loaded is not the technical problem to be solved and the object of protection of the utility model. At the same time, the communication methods between the devices all adopt the existing communication methods, which are not the innovation points of the present application.

[0018] In summary, the utility model has the following beneficial technical effects:

[0019] 1. The device is provided with a vacuum pump and a plug valve. The plug valve blocks the discharge pipe. After the vacuum pump is started, negative pressure is applied to the silo. When positive pressure is required for discharge, the plug valve is turned, and the copper-gold powder can be automatically discharged. A closed space is formed by the plug valve, and the copper-gold powder is directly negatively applied to the silo through the feed pipe, which helps to avoid the copper-gold powder being easily oxidized when being applied.

[0020] 2. The device is provided with a filter and a back-blowing air bag. When feeding under negative pressure, the vacuum pump works continuously, and the copper and gold powder can be filtered through the filter, so that the copper and gold powder entering the silo and moving upward adheres to the bottom of the filter. The back-blowing air bag is started for blowing, so that the copper and gold powder at the bottom of the filter is backblown into the silo, and then fed to other processes through the discharge pipe for coating production, which is beneficial to avoid the negative pressure feeding of the copper and gold powder into the vacuum pump, affecting the operation of the vacuum pump, and avoiding waste of raw materials.

[0027] The following is combined with Figure 1-4 The utility model is described in further detail.

[0028] The utility model embodiment discloses a feeding mechanism for producing copper and gold powder coating.

[0029] Reference Figure 1 , 4 , including an electrical module and a mechanical module. The mechanical module includes a silo 1 and a vacuum pump 2 (known technology). The top of the silo 1 is fixedly connected to the input end of the vacuum pump 2. After the vacuum pump 2 is started, a negative pressure is formed inside the silo 1, and then under the action of pressure, the copper-gold powder enters the interior of the silo 1 through the feeding pipe 8. A filter 3 (known technology) is fixedly connected to the interior of the silo 1. When feeding under negative pressure, the vacuum pump 2 works continuously, and the filter 3 is used to prevent the copper-gold powder from being fed into the vacuum pump 2 under negative pressure. The electrical module includes a control system (known technology). The control system has modules such as controlling the opening and closing of related components, receiving and transmitting data, and judging and processing. Employees can conveniently control the opening and closing of the vacuum pump 2, the filter 3, the stopcock 7 (known technology) and the back-blowing air bag 10 (known technology) by operating the control system.

[0030] Reference Figure 2 , 34. A vent pipe 4 is provided on the outer surface of the silo 1. A pressure gauge can be installed on the outer surface of the silo 1 to detect the pressure inside the silo 1 through the pressure gauge to prevent the internal pressure of the silo 1 from exceeding the limit of the silo 1. A vent valve 5 is fixedly connected to the inside of the vent pipe 4. Both the vent pipe 4 and the vent valve 5 are protective devices. When the pressure in the silo 1 is too low and the stopcock 7 cannot be turned normally, the vent valve 5 is opened to balance the air pressure inside and outside the silo 1 through the vent pipe 4. When negative pressure is applied, the vent valve 5 is closed so that when the vacuum pump 2 is started, the silo 1 can be in a negative pressure state.

[0031] Reference Figure 1 , 3 4. A discharge pipe 6 is fixedly connected to the bottom of the silo 1, and a plug valve 7 is fixedly connected to the outer surface of the discharge pipe 6. The plug valve 7 is a partition gate, which blocks the discharge pipe 6 during negative pressure feeding. During positive pressure unloading, the copper-gold powder can be automatically discharged by turning the plug valve 7.

[0032] Reference Figure 1 , 2 , 3, 4. The outer surface of the silo 1 is fixedly connected with a feed pipe 8. When negative pressure is formed in the silo 1, negative pressure is also formed in the feed pipe 8, so that the copper-gold powder inside the raw material box 9 is fed under negative pressure. The other end of the feed pipe 8 is fixedly connected with the raw material box 9, and the raw material box 9 is filled with copper-gold powder.

[0033] Reference Figure 4 The filter 3 is located above the feed pipe 8 to prevent the copper-gold powder from directly entering the interior of the vacuum pump 2 and then being discharged into the atmosphere, causing raw material loss and air pollution.

[0034] Reference Figure 4 A back-blowing air bag 10 is fixedly connected to the interior of the silo 1. The back-blowing air bag 10 is located between the filter 3 and the vacuum pump 2. After the copper-gold powder is negatively pressure fed into the silo 1, it is filtered by the filter 3, and a part of the copper-gold powder remains at the bottom of the filter 3. The control system controls the blowing of the back-blowing air bag 10, so that the copper-gold powder at the bottom of the filter 3 is back-blown into the interior of the silo 1 and enters the discharge pipe 6.

[0035] The implementation principle of a feeding mechanism for copper-gold powder coating production in the embodiment of the utility model is as follows:

[0036] After the worker operates the control system to start the vacuum pump 2, negative pressure loading occurs in the silo 1, and the filter 3 prevents the copper and gold powder from entering the vacuum pump 2. At this time, the stopcock 7 closes the discharge pipe 6. The stopcock 7 is rotated by operating the control system to allow the copper and gold powder to enter the discharge pipe 6, thereby completing automatic vacuum negative pressure loading and positive pressure unloading.

[0037] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
