Detailed description of the embodiments

[0027] To further explain the object, technical solutions, and advantages of the embodiments of the disclosure, the technical solutions in the embodiments of the disclosure are described clearly and completely with reference to the figures in the embodiments of the disclosure. Of course, the described embodiments represent a portion of the embodiments of the disclosure, rather than all embodiments. In general, the components of the embodiments of the disclosure described and illustrated in the figures herein can be arranged and configured in various configurations.

[0028] Therefore, the detailed description of the embodiments of the disclosure provided in the figures should not serve to limit the claimed scope of the disclosure, but merely represents selected embodiments of the disclosure. All further embodiments that a person skilled in the art can achieve without inventive step based on the embodiments in the disclosure fall within the claimed scope of the disclosure.

[0029] It should be noted that similar reference symbols and letters denote similar objects in the following figures. Therefore, if an object is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] It should be noted in the description of the revelation that the orientation or positional relationship indicated by terms such as "center," "top," "bottom," "left," "right," "vertical," "horizontal," "inside," "outside," or the like, is based on the orientation or positional relationship depicted in the figures or refers to the orientation or positional relationship in which the product is usually arranged when used, according to the revelation. Furthermore, terms such as "first," "second," and "third" serve only to differentiate the description and are not to be understood as indicating or implying any relative importance.

[0031] Furthermore, terms like "horizontal," "vertical," etc., do not mean that the parts must be absolutely horizontal or vertical, but can be slightly inclined. For example, "horizontal" simply means that the orientation is described as more horizontal than "vertical," and does not mean that this structure must be perfectly horizontal, but can be slightly inclined.

[0032] It should further be noted in the description of the disclosure that, unless expressly specified and defined otherwise, terms such as "arranged," "attached," "coupled," and "connected" are to be understood in a broad sense. This can refer to a fixed connection, a detachable connection, or a one-piece connection; a mechanical connection or an electrical connection; a direct connection, an indirect connection via an intermediate medium, or an internal connection between the two elements. The specific meaning of the aforementioned terms within the context of the disclosure will be readily apparent to the person skilled in the art.

[0033] As in Fig. 1 to Fig. As shown in Figure 3, this disclosure presents an integrated dosing and shaking machine comprising a frame, a first housing 210 attached to the frame, a second housing 220, a dosing system, and a shaking system. As shown in Figure 3, the machine is described in Figure 3. Fig. 4 to Fig. As shown in Figure 8, the dosing system comprises a plurality of liquid ink cartridges 121 containing different materials to provide materials as needed. The dosing system further comprises a base 110 rigidly connected to the frame, a turntable 122 mounted on the base 110, and a first drive unit 140, which is attached to the base 110 and is drive-connected to the turntable 122. As shown in Figure 8, the dosing system comprises a plurality of liquid ink cartridges 121 containing different materials to provide materials as needed. Fig. As shown in Figure 4, the liquid color cartridges 121 are arranged on the turntable 122, and the color dosing unit 120 consists of these cartridges and the turntable 122. The first drive unit 140 is connected to the turntable 122 for drive purposes in order to select the desired liquid color cartridges 121 and thus obtain different materials. It should be noted that in this disclosure, the liquid color cartridge 121 is not limited to a cylindrical structure filled with liquid color, but is to be understood as a container filled with a material.

[0034] Furthermore, the first housing 210 and the turntable 122 are located on the same side of the base 110, and the turntable 122 and the liquid ink cartridges 121 are enclosed by the first housing 210. The first housing 210 and the first drive unit 140 are located on opposite sides of the base 110. Disassembly of the first drive unit 140 can be facilitated by mounting the ink metering unit 120 and the first drive unit 140 on opposite sides of the base 110.

[0035] It should be noted that the phrase "the paint metering unit 120 and the first drive unit 140 are attached to the two opposite sides of the base 110" is to be understood as meaning that the paint metering unit 120 and the first drive unit 140 are each to be removed from different sides of the base 110, but rather that the entire assembly of the paint metering unit 120 or the first drive unit 140 is not located entirely on both sides of the base plate. In this disclosure, although the first drive unit 140 and the paint metering unit 120 are attached to the two opposite sides of the base 110, the assembly of the first drive unit 140 extends partially through the base and is connected to the rotary disk 122 in the paint metering unit in a drive-related manner in order to drive the rotary disk 122 to rotate.

[0036] Furthermore, the shaking system is located below the base 110. As in Fig. As shown in Figure 1, the second housing 220 and the first drive unit are located on the same side of the base 110. The second housing 220 encloses the shaking system, and the first drive unit 140 is located outside the second housing 220. In the integrated dosing and shaking machine according to this disclosure, the first drive unit 140 is not enclosed by either the first housing 210 or the second housing 220, thus the first drive unit 140 can be easily disassembled.

[0037] This disclosure does not contain any specific limitation on the structure of the base 110. In some embodiments, the base 110 is a plate-shaped component, the space receiving the dosing unit is bounded by the base 110 and the first housing 210, and the space receiving the shaking system is bounded by the base 110 and the second housing 220.

[0038] In some embodiments of the metering system according to this disclosure, as in Fig. 4 and Fig. As shown in Figure 5, the turntable 122 has a plurality of fitting sections 1221 arranged along a circumference and serving to fit with the first drive unit 140, so that the first drive unit 140 can drive the turntable 122 to rotate, the center of rotation of the turntable 122 being the center of the circumference. Furthermore, the liquid ink cartridges 121 are located within this circumference, and the first drive unit 140 is located outside this circumference. The placement of the first drive unit 140 outside the circumference is to be understood as allowing it to be removed from the outside of the circumference. In some embodiments, the first drive unit 140 is positioned outside the circumference by placing the connection point between the first drive unit 140 and the base 110 outside the circumference.

[0039] As in Fig. 4 and Fig. As shown in Figure 5, since the circumference of the circle encloses the liquid ink cartridges 121, the circumference lies close to the edge of the turntable 122, and the first drive unit 140 is mounted outside the circumference, so that the mounting point of the first drive unit 140 is close to the edge of the turntable 122. This makes it easier for the first drive unit 140 to be located outside the second housing 220, and at the same time the overall size of the integrated dosing and shaking machine is relatively smaller, thus making the structure more efficient.

[0040] The metering unit according to this disclosure further comprises a valve switching unit 130 mounted on the base 110, which serves to fit a valve 1211 on a liquid paint cartridge 121 and to open the valve in order to allow the material in the liquid paint cartridge 121 to flow out through an outlet of the valve 1211. In this disclosure, the valve 1211 connected to the liquid paint cartridge 121 has an outlet. Opening the valve 1211 means that the outlet of the valve 1211 is opened so that the material in the valve 1211 can flow out.

[0041] The metering system according to this disclosure drives the rotary disk 122 to rotate by means of the first drive device 140, so that various liquid color cartridges 121 rotate successively towards the valve 1211 and align with the valve switching unit 130, whereby various materials in the liquid color cartridges 121 flow out through the outlet of the valve 1211 under the action of the valve switching unit 130 to complete the metering process of the materials. Furthermore, as in Fig. As shown in Figure 3, a discharge opening 111 is arranged on the base 110. After the valve 1211 is fitted with the valve switching unit 130, the outlet on the valve 1211 is located above the discharge opening 111. A container for receiving the material is arranged below the discharge opening 111.

[0042] This disclosure does not restrict the relative position of the valve switching unit to the first drive unit 140. In some preferred embodiments, as in Fig. As shown in Figure 2, the first segment, which connects the mounting location of the valve switching unit 130 and the center of rotation, and the second segment, which connects the mounting location of the first actuator 140 and the center of rotation, form an obtuse angle. The first segment 410 and the second segment 420 lie in the same horizontal plane. One end of the first segment 410 can be any point in the area of ​​the mounting location of the valve switching unit 130, or the projection of the geometric center of the valve switching unit 130 at the mounting location onto the horizontal plane. One end of the second segment 420 can be any point in the area of ​​the mounting location of the first actuator 140, or the projection of the geometric center of the first actuator 140 at the mounting location onto the horizontal plane. As shown in Figure 2. Fig. As shown in Figure 2, one end of the first section 410 connects the projection of the geometric center of the valve switching unit 130 at the mounting location to the horizontal plane, and one end of the second section 420 connects the projection of the geometric center of the first actuator 140 at the mounting location to the horizontal plane. In this embodiment, the valve switching unit is located relatively far from the first actuator 140, and this can reduce the adverse effects on the other during disassembly of one of the two.

[0043] This disclosure does not restrict the design of the first drive unit 140, as long as it is possible to fit with the mating section 1211 to drive the turntable 1222 to rotate. In some embodiments, the first drive unit 140 comprises a first drive element 141 and a first drive wheel 142. Along the circumference of the first drive wheel 142, there are a plurality of teeth which, during the rotation of the first drive wheel 142, drive the turntable 1222 to rotate and fit successively with the mating sections 1221.

[0044] This disclosure does not restrict the specific design of the first drive wheel 142. Depending on the fitting section 1221, the first drive wheel 142 can also have a different design. For example, in an embodiment where the fitting section has a hole structure, the first drive wheel 142 can be a gear or sprocket, with a toothed section of the first drive wheel 142 projecting into the hole structure of the turntable 122. In an embodiment where the turntable 122 is provided with a toothed rim, the fitting section 1221 represents the toothed structure of the toothed rim, and the first drive wheel can be a gear that can engage with the toothed rim.

[0045] This disclosure does not restrict the specific design of the valve switching unit 130, as long as it is possible to drain the material from a liquid paint cartridge 121 using the valve switching unit 130.

[0046] In some embodiments, as in Fig. As shown in Figure 8, the valve 1211 on the liquid ink cartridge 121 comprises a first drive rod 12111, wherein the opening and closing of the outlet of the valve 1211 is enabled by rotation of the first drive rod 12111. The valve switching unit 130 comprises a rotatable drive disc 131, which is provided with a second drive rod 132. As shown in Fig. As shown in Figure 9, the driven disc 131 is connected to a second drive element 133, and the driven disc 131 is rotated under the action of the second drive element 133 to push the first driven rod 12111, thus opening the outlet of the valve 1211. This disclosure does not restrict the direction of rotation of the axis of the first driven rod 12111 and the second driven rod 132. The first driven rod 12111 and the second driven rod 132 can be rotated about a horizontal or a vertical axis.

[0047] This disclosure does not restrict the form of the second drive element 133. For example, the second drive element 133 may be an electric motor connected to the drive disc 131. There is also no restriction on the mounting location of the second drive element 133, as long as the mounting location of the second drive element 133 is fixed to the base 110.

[0048] Furthermore, the valve 1211 is connected to a pump body 123, which is provided with a piston rod 1231, and a pressure plate 12311 is arranged on the piston rod 1231. A pressure force is exerted on the material in a liquid paint cartridge 121 during the movement of the piston rod 1231, so that the material in the liquid paint cartridge 121 is discharged through the outlet of the valve 1211. The valve switching unit 130 further comprises a pressure piece 134 that is movable back and forth in a vertical direction, wherein the pressure piece 134 has a groove-shaped structure that fits with the pressure plate 12311, and the pressure plate 12311 is located in the groove-shaped structure when the valve 1211 is rotated with the rotary disk 122 and fits into the valve switching unit.The pressure piece 134 is connected to a third drive element, which serves to move the pressure piece 134 in a vertical direction, so that the side wall of the groove-shaped structure pushes the pressure plate 12311 together with the pressure piece 134 for movement. The above-mentioned design of the pump body and the valve switching unit 130 represents only one embodiment of this technical solution. Other embodiments with a differently designed pump body and a corresponding valve switching unit are also conceivable.

[0049] This disclosure does not restrict the specific design of the third drive element. In some embodiments, the third drive element is a threaded spindle-nut mechanism, wherein the threaded spindle is arranged vertically and the nut is rigidly connected to the pressure piece 134. By means of the rotation of the threaded spindle, the pressure piece 134 is moved by the nut in a vertical direction to discharge the material in the liquid ink cartridge 121 from the outlet.

[0050] In the above technical solution, the valve switching unit 130 further comprises a pressure piece 134 for dispensing the material in the liquid paint cartridge 121 and a third drive element, such that the material in the liquid paint cartridge 121 flows out through the outlet after the outlet of the valve 1211 is opened by the drive disc 131 and the second drive rod 132. In a specific embodiment, the valve 1211 has a first channel connected to the liquid paint cartridge 121 and a second channel connected to the outlet, wherein both the first channel and the second channel are fluidically connected to the inner chamber of the pump body 123, so that the material in the first channel reaches the outlet via the second channel under the action of the pump body 123.In some further embodiments of this disclosure, a differently constructed liquid paint cartridge 121 and a differently constructed valve 1211 can of course be used to discharge the material.

[0051] In some preferred embodiments of this disclosure, the dosing system further comprises a display panel and a control unit, which are signal-connected to automatically complete the dosing process. The control unit is further signal-connected to the first drive element 141, the second drive element 133, and the third drive element to drive the first drive element 141, the second drive element 133, and the third drive element according to the specified requirements and to display the progress of the dosing process by means of the display panel.

[0052] In the integrated dosing and shaking machine according to this disclosure, there is no restriction on the specific design of the shaking system, as long as it can shake the different materials in the container.

[0053] In some embodiments, the shaking system comprises a vibration unit 300, wherein the vibration unit 300 has a support table 370 and the vibrating working plane of the support table serves to support the container. It should be readily apparent to those skilled in the art that the vibration unit 300 can generate vibrations and transmit these vibrations to the container on the vibrating working plane.

[0054] This disclosure does not restrict the specific design of the vibration unit 300. In one embodiment, a structure disclosed in the prior art (publication number: CN2772611Y) may be used. Specifically, as described in Fig. 10 and Fig.As shown in Figure 11, the vibration unit 300 comprises an inner frame 310 and a middle frame 320, which are movable relative to each other, wherein the support table 370 is arranged on the inner frame 310 and the middle frame 320 is provided with a fourth drive element 330.

[0055] The fourth drive element 330 is drivingly connected to a second drive wheel 340, and the second drive wheel 340 is connected to a connecting shaft 350, one end of the connecting shaft 350 being fixedly connected to the second drive wheel 340 and the other end being rotatably connected to the inner frame 310. During rotation of the drive wheel, the connecting shaft moves in a circular motion with the center of rotation of the drive wheel as the circle center, thus moving the inner frame 310. Thus, the inner frame 310 is moved along with the rotation of the drive wheel. The support table 370 arranged on the inner frame 310 exhibits a movement in the vertical direction, which makes it possible to shake the material held in the container located on the oscillating work plane.

[0056] Furthermore, the vibrating unit 300 comprises a central frame 320 rigidly connected to the inner frame 310, wherein a damping unit 380 is connected between the inner frame 320 and the frame, and the central frame 320 is provided with a vertically movable cover plate 360. The upper part of the container standing on the vibrating working plane can be closed by moving the cover plate 360 ​​downwards, thereby preventing material from splashing out of the container during shaking.

[0057] In some preferred embodiments of this disclosure, the shaking system further comprises a damping unit 380 connected between the vibrating unit 300 and the frame to reduce the vibrations transmitted to the frame, thus making the integrated metering and shaking machine more stable during operation. By way of example, the damping unit 380 comprises a plurality of damping struts having a damping function, wherein the damping strut is connected at one end to the central frame 320 and at another end to the frame, thereby reducing the vibrations transmitted from the vibrating unit 300 to the frame.

[0058] The foregoing description is only one preferred embodiment of the present disclosure and is not intended to limit it. For a person skilled in the art, the present disclosure may exhibit various modifications and variations. Changes, equivalent replacements, improvements, etc., made in accordance with the spirit and principles of the disclosure fall within the scope of protection of the disclosure.
