Description

Technical Field

[0001] This invention relates to the field of decoration equipment technology, and more specifically, to a putty spraying machine. Background Technology

[0002] Currently, most large (or industrial) putty spraying machines on the market are driven by older stator-rotor motors. However, the driving power of a stator-rotor motor is entirely determined by the number of coils; more coils mean a heavier and larger motor. Furthermore, large putty spraying machines require additional fuel tanks to provide power, resulting in heavier equipment, larger footprint, inconvenience for users to move or use, and high resource consumption, leading to waste.

[0003] Therefore, overcoming the above problems is a technical challenge that urgently needs to be addressed. Summary of the Invention

[0004] The purpose of this invention is to provide a putty spraying machine that can improve the above-mentioned problems.

[0006] This invention provides a putty spraying machine, which includes a housing, an external rotor motor, a pressure sensor, a control device, an oil-free drive device, and a hydraulic high-pressure pump head;

[0007] Both the external rotor motor and the oil-free drive device are housed inside the housing.

[0008] The output shaft of the external rotor motor is connected to the input end of the oil-free drive device; the output end of the oil-free drive device is connected to the hydraulic high-pressure pump head.

[0009] The pressure sensor is mounted on the hydraulic high-pressure pump head;

[0010] Both the pressure sensor and the external rotor motor are electrically connected to the control device.

[0011] The control device is located on the outer surface of the enclosure.

[0012] In a preferred embodiment of the present invention, the control device includes a control box and a PCB board with integrated control circuitry; one end of the pressure sensor is connected to the PCB board via a data cable.

[0013] The PCB board is fixed inside the control box;

[0014] The control box is mounted on the outer surface of the enclosure.

[0015] In a preferred embodiment of the present invention, the control box includes a body and a cover, wherein the cover is disposed on the body;

[0016] The PCB board is installed inside the body;

[0017] The cover has a control area and a sensor hole for the data cable to pass through.

[0018] In a preferred embodiment of the present invention, the control area is provided with a display screen, which is connected to the PCB board.

[0019] In a preferred embodiment of the present invention, the housing includes a first housing and a second housing, the external rotor motor is disposed in the first housing, the oil-free drive device is disposed in the second housing, the first housing and the second housing are connected; the control box is disposed on the outer surface of the first housing.

[0020] In a preferred embodiment of the present invention, the second housing is provided with heat dissipation holes, which are located on the side of the heat dissipation device that contacts the second housing.

[0021] In a preferred embodiment of the present invention, the heat dissipation device includes a heat sink, which is electrically connected to the PCB board.

[0022] The putty spraying machine provided by the present invention comprises a housing, an external rotor motor, a pressure sensor, a control device, an oil-free drive device, and a hydraulic high-pressure pump head. Both the external rotor motor and the oil-free drive device are housed within the housing. The output shaft of the external rotor motor is connected to the input end of the oil-free drive device.

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.

[0033] Please refer to Figures 1 to 7This embodiment provides a putty spraying machine 100, which includes an external rotor motor 110, a hydraulic high-pressure pump head 130, a control device 140, a housing 150, a pressure sensor 160, and an oil-free drive device 170.

[0034] The external rotor motor 110 is installed inside the housing 150. The output shaft of the external rotor motor 110 is connected to the input end of the oilless drive device 170, and the output end of the oilless drive device 170 is connected to the hydraulic high-pressure pump head 130.

[0035] The external rotor motor 110 is connected to the control device 140 so that the control device 140 can control the speed and working state of the external rotor motor 110 (e.g., working or stopping).

[0036] It should be noted that because the external rotor motor 110 has a larger torque, it is smaller and lighter than an internal rotor motor of the same power.

[0037] It should be noted that in actual use, the coil of the external rotor motor 110 can be adjusted according to the required power, but this will not increase the size of the external rotor motor 110.

[0038] Optionally, the external rotor motor 110 is a brushless motor.

[0039] Optionally, the external rotor motor 110 includes an external rotor 111 and a housing 113.

[0040] The outer rotor 111 is located inside the housing 113; the outer rotor 111 is also provided with a bearing hole 112 for the bearing to pass through the bearing hole 112.

[0041] Optionally, the external rotor motor 110 also includes a stator 114, which is disposed within the housing 113 and located within the external rotor 111.

[0042] Optionally, the hydraulic high-pressure pump head 130 is used to connect to an external hydraulic gun (not shown) to provide the hydraulic gun with the liquid to be sprayed.

[0043] The control device 140 is used to control the drive of the external rotor motor 110.

[0044] The control device 140 includes a control box 141, a PCB board with integrated control circuitry, and 143.

[0045] Optionally, the control box 141 is used to fix the PCB board 143 (i.e., the PCB) that integrates the control circuitry. For example, the PCB board 143 is fixed inside the control box 141 by screws.

[0046] Optionally, the control box 141 is mounted on the outer surface of the enclosure 150 to facilitate user operation of the control box 141.

[0047] Optionally, the control box 141 is rectangular, for example, a cuboid.

[0048] Of course, in actual use, the control box 141 can also be other shapes, such as a cube or cylinder, or even a polygonal irregular shape. No specific limitation is made here.

[0049] It should be understood that the control box 141 has sufficient space to accommodate the PCB board 143.

[0050] Optionally, the control box 141 includes a body 1411 and a cover 1413, the cover 1413 covering the body 1411 (for example, the cover 1413 is connected to the body 1411 by screws); the PCB board 143 is installed inside the body 1411.

[0051] Optionally, the cover 1413 is provided with a control area 1415 and a sensor hole 1417 for the data line to pass through.

[0052] Optionally, the control box 141 is made of a metal material, such as aluminum, iron, stainless steel, etc.

[0053] Of course, in actual use, the controller 141 can also be made of plastic or glass, and no specific limitation is made here.

[0054] Optionally, the control area 1415 is provided with a display screen 1419, which is connected to the PCB board 143.

[0055] Optionally, the display screen 1419 is used to display the pressure value of the hydraulic high-pressure pump head 130 collected by the pressure sensor 160 in real time for user viewing.

[0056] Optionally, the PCB board 143 can dynamically set the driving voltage of the external rotor motor 110, such as 110V, 220V, etc., without modifying the control box 141. It only needs to adjust the number of coils of the external rotor motor 110 according to the driving voltage, which makes it easier to adjust the driving voltage of the motor and shortens the time for adjusting the driving voltage of the motor.

[0057] Optionally, the PCB board 143 is provided with a female port for the pressure sensor 160 to be plugged in and out.

[0058] It should be understood that the data line connected to the pressure sensor 160 has a male port corresponding to the female port, so as to facilitate quick insertion and removal of the pressure sensor 160.

[0059] It should be noted that the control circuit integrated on the PCB board 143 can be pre-programmed, and this application does not limit the specific composition of the control circuit.

[0060] Optionally, the housing 150 is used to mount the external rotor motor 110 and the oilless drive device 170.

[0061] Optionally, the enclosure 150 is made of stainless steel.

[0062] Of course, in actual use, the enclosure 150 can also be made of other materials, such as aluminum alloy.

[0063] Optionally, the shape of the housing 150 is rectangular.

[0064] Optionally, the housing 150 includes a first housing 151 and a second housing 153, the external rotor motor 110 is disposed in the first housing 151, the oil-free drive device 170 is disposed in the second housing 153, the first housing 151 and the second housing 153 are connected; the control box 141 is disposed on the outer surface of the first housing 151.

[0065] Optionally, the first housing 151 and the second housing 153 are integrally formed.

[0066] It should be understood that a channel (e.g., a through hole) must be provided between the first housing 151 and the second housing 153 to facilitate the connection between the external rotor motor 110 and the oil-free drive device 170.

[0067] Optionally, the oil-free drive unit 170 is externally connected to an energy storage device 178, which is used to reduce pulses.

[0068] Optionally, the oilless drive unit 170 can be a drive pump, such as a hydraulic pump. Specifically, one end of the hydraulic high-pressure pump head 130 is connected to the cooling assembly 180 via an oil inlet pipe J, and the cooling assembly 180 is connected to a filter (that is, the oil inlet pipe J passes through the cooling assembly 180 and is connected to the filter). The hydraulic high-pressure pump head 130 is connected to the oilless drive unit 170 via an oil outlet pipe C.

[0069] Optionally, one end of the pressure sensor 160 is connected to the PCB board 143 via a data cable, and the pressure sensor 160 is fixed to the hydraulic high-pressure pump head 130 (for example, by binding it to the hydraulic high-pressure pump head 130 with a bandage) for real-time monitoring of the pressure of the hydraulic high-pressure pump head 130 during operation.

[0070] In the above implementation process, by setting a pressure sensor 160 and a PCB board 143 with integrated control circuit, the pressure of the hydraulic high-pressure pump head 130 can be monitored in real time by the pressure sensor 160. This allows the PCB board 143 with integrated control circuit to dynamically adjust the output voltage of the external rotor motor 110 according to the pressure, thereby realizing the variable speed operation of the external rotor motor 110 and saving energy.

[0071] Alternatively, the pressure sensor 160 can also be mounted on the oil-free drive unit 170, for example, on the outer surface of the second housing 153.

[0072] In one possible embodiment, the putty spraying machine 100 further includes a heat dissipation device 180, which is mounted on the outer surface of the second housing 153.

[0073] Optionally, the second housing 153 is provided with heat dissipation holes (not shown in the figure), and the heat dissipation holes are located on the side of the heat dissipation device that contacts the second housing 153.

[0074] Optionally, the heat dissipation device 180 includes a heat sink 181, which is electrically connected to the PCB board 143.

[0075] It should be noted that the power supply of the putty spraying machine 100 in this application is an external mains power supply.

[0076] It should be noted that the putty spraying machine 100 in this application has greatly reduced its size by eliminating the oil tank and using an external rotor motor 110, making the putty spraying machine 100 more convenient.

[0077] It should be understood that although the oil tank present in the prior art has been removed in this application, there will still be lubricating oil in the putty spraying machine 100. However, the lubricating oil is only a very small part. Therefore, removing the oil tank in the prior art has no effect on the lubricating oil in this application.

[0078] In summary, the putty spraying machine provided by this invention comprises a housing, an external rotor motor, a pressure sensor, a control device, an oil-free drive device, and a hydraulic high-pressure pump head. Both the external rotor motor and the oil-free drive device are housed within the housing. The output shaft of the external rotor motor is connected to the input end of the oil-free drive device. The output end of the oil-free drive device is connected to the hydraulic high-pressure pump head. The pressure sensor is located on the hydraulic high-pressure pump head. Both the pressure sensor and the external rotor motor are electrically connected to the control device, which is located on the outer surface of the housing. This application eliminates the need for an additional oil tank by using an external rotor motor, providing sufficient kinetic energy to the putty spraying machine. This effectively reduces the weight and size of the putty spraying machine, making it more convenient for users. Furthermore, the elimination of an oil tank effectively saves energy, conserves resources, and reduces operating costs.
