DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1: Reference Figure 1-8 As shown: a modular combined production equipment that can adapt to different paint thinner formulas, including a plurality of pumping mechanisms 4, one end of the pumping mechanism 4 is connected to a mixing tank 3 through a conduit, and the other end of the pumping mechanism 4 is connected to a stirring tank 2 through a conduit, and the pumping mechanism 4 is used to pump the paint thinner in the mixing tank 3 to the stirring tank 2 for mixing and proportioning, and a metering and distributing mechanism 5 is arranged between two adjacent pumping mechanisms 4, and the metering and distributing mechanism 5 includes a tapered column 51, a threaded column 52 and a cylinder 53, and a connecting component 55 is connected between the threaded column 52 and the cylinder 53, and the connecting component 55 includes a threaded sleeve 551, squeezing roller 552 and key sleeve 553, the threaded sleeve 551 is threadedly connected to the threaded column 52, the outer wall of the cylinder 53 is fixedly connected with a flat key 531, the cylinder 53 is slidingly connected to the key sleeve 553 through the flat key 531, the squeezing roller 552 is fixedly connected to the key sleeve 553, the outer wall of the squeezing roller 552 fits the outer wall of the conical column 51, the threaded sleeve 551 is rotatably connected to the key sleeve 553, the conical column 51 is transmission-connected to one of the pumping mechanisms 4, the cylinder 53 is transmission-connected to the other pumping mechanism 4, and the gap between the conical column 51 and the cylinder 53 is equal everywhere.

[0023] In this embodiment, the paint thinner formula is customized according to the target paint types such as nitro paint, alkyd paint, water-based paint, etc. and the application scenarios. In order to meet the requirements of raw material supply in different formulas, the raw materials of each paint thinner are pumped and proportioned by a separate pumping mechanism 4. Different raw materials are stored in different mixing tanks 3 respectively, and finally are uniformly pumped and transferred to the mixing tank 2 by the pumping mechanism 4 for proportioning and mixing. The pumping mechanism 4 uses rotation as power, and the capacity of the raw materials it pumps is determined by the rotation speed. A certain amount of raw materials can be replenished every time the input end rotates one week. A metering and distribution mechanism 5 is installed between different pumping mechanisms 4. The metering and distribution mechanism 5 controls the rotation speeds of two connected pumping mechanisms 4, so that the two pumping mechanisms 4 pump and proportion different raw materials according to the specified mixing ratio. The two ends of the conical column 51 and the cylindrical column 53 are respectively connected to the two pumping mechanisms 4 on both sides. The axes of the conical column 51 and the cylindrical column 53 are inclined relative to each other. Although the conical column 51 is a conical structure and the cylindrical column 53 is a cylindrical structure, their gaps are equal everywhere. No matter where the pressing roller 552 slides, it can always maintain a tight fit with the outer surface of the conical column 51. By rotating the threaded column 52, the threaded sleeve 551 can be made to slide relatively. The sliding of the threaded sleeve 551 drives the key shaft sleeve 553 to move, thereby controlling the rotation of the cylindrical column 53 and the conical column 51 at different eccentric positions. The cylindrical column 53 and the pressing roller 552 are connected by a flat key 531. When the cylindrical column 53 rotates, it drives the pressing roller 552 to rotate. Since the pressing roller 552 is in contact with the outer surface of the conical column 51, the rotation of the pressing roller 552 drives the conical column 51 to rotate. Since the output rotation speed of the conical column 51 is fixed, when the contact position between the pressing roller 552 and the conical column 51 is thinner, the overall rotation speed of the conical column 51 is faster. When the contact position between the pressing roller 552 and the conical column 51 is thicker, the overall rotation speed of the conical column 51 is slower, so that the rotation of the cylindrical column 53 can be adjusted, thereby controlling the pumping ratio of the two pumping mechanisms 4.

[0024] Embodiment Two: Figure 1 , Figure 4 , Figure 5 and Figure 7 As shown in and, the pumping mechanism 4 includes a cylinder 41. An eccentric cylinder 45 is provided on the inner side wall of the cylinder 41, and a slot 450 is opened on the side wall of the eccentric cylinder 45. A connecting pin 47 is rotatably connected to the side wall of the cylinder 41. A baffle 46 slides on the outer side wall of the connecting pin 47. The connecting pin 47 is located at the center position of the eccentric cylinder 45, and the connecting pin 47 is fixedly connected to the eccentric cylinder 45. Both ends of the baffle 46 pass through the slot 450 and overlap with the inner wall of the cylinder 41. A circular plate 42 is fixedly connected to one side of the cylinder 41. A sealing plug is fixedly connected to the connection between the cylinder 41 and the circular plate 42. A liquid supply sleeve 44 is fixedly connected to the bottom end of the cylinder 41. Sealing joints 43 are communicated with both ends of the liquid supply sleeve 44. A second through hole 440 is opened at the axis of the liquid supply sleeve 44. A first through hole 410 is opened at the position of the cylinder 41 corresponding to the second through hole 440. Both sealing joints 43 are connected to a conduit.

[0025] In this embodiment, the working principle of the pumping mechanism 4 for pumping raw materials is as follows. When the servo motor 6 or the metering and distributing mechanism 5 drives the connecting pin 47 to rotate, the connecting pin 47 drives the eccentric cylinder 45 to rotate in the cylinder 41. Since the eccentric cylinder 45 is located at an eccentric position in the cylinder 41, when the eccentric cylinder 45 rotates, the slotted opening 450 faces different directions of the cylinder 41, causing the baffle 46 connected to the outside to face different directions of the cylinder 41. The length of the baffle 46 is fixed, and both ends of the baffle 46 always remain in close contact with the inner wall of the cylinder 41 and rotate. As the baffle 46 faces different directions, the volumes of the cavities on both sides are different. Referring to the Figure 4 description in the appendix, the volume of the cavity on the left side increases, and the volume of the air on the right side decreases. When the baffle 46 moves to the bottom end of the eccentric cylinder 45, the cavities divided by the baffle 46 are switched. The volume of the cavity on the left side always continuously increases, and the volume of the air on the right side always continuously decreases. By utilizing the positive and negative pressure changes generated by the volume changes, the raw materials on the left side are pumped to the right side at this time, realizing the pumping and transportation function of the raw materials. Among them, the pumping flow rate of the raw materials by the pumping mechanism 4 is determined by the rotation speed of the connecting pin 47. The faster the rotation speed per unit time, the more raw materials are pumped, realizing the function of the shaping pumping movement of the raw materials.

[0026] Embodiment Three: As Figure 1-8 shown, one end of the threaded column 52 is fixedly connected to a rocker 54, and an anti-slip sleeve is fixedly connected to the outer wall of the rocker 54. One end of the tapered column 51 is fixedly connected to a pin joint one 510, and one end of the cylinder 53 is fixedly connected to a pin joint two 530. Both the pin joint one 510 and the pin joint two 530 are fixedly connected to the corresponding connecting pin 47. The bottom end of the pumping mechanism 4 is fixedly connected to a base 1, the top end of the base 1 is fixedly connected to a servo motor 6, and the output end of the servo motor 6 is fixedly connected to one of the connecting pins 47. Pressure gauges are installed on the tank walls of the mixing tank 3, and a flow meter is installed on the conduit. A motor is installed on the surface of the stirring tank 2, and a mixing roller is connected through the motor. The mixing roller stirs the ingredients inside the stirring tank 2, and heating elements are installed inside the stirring tank 2.

[0027] In this embodiment, the entire production equipment is divided into several modules: a pumping module, a metering module, a mixing module and a temperature control module, wherein different pumping modules are combined to work, and a metering distribution mechanism 5 is used to adjust the ratio of the pumping modules. The metering modules are installed in the conduits at both ends of the sealing joint 43, one of which is connected between the pumping mechanism 4 and the mixing tank 3. The metering module is used to record the input capacity of the raw materials, and the other conduit is connected between the pumping mechanism 4 and the stirring tank 2. The mixing module is composed of a motor and a mixing roller on the stirring tank 2, which is used to fully mix different raw materials. The pumping module is realized by the centrifugal pumping principle of the pumping mechanism 4 to realize the unidirectional function of the raw materials. In order to better In order to improve the raw material preparation environment and extend the material storage time, a temperature control module is also arranged inside the mixing tank 2 to control the mixing or storage of the materials in the mixing tank 2 within a certain temperature range, so as to improve the quality of the finished product of the paint thinner. A rocker 54 is installed at one end of the threaded column 52 so that the user can manually adjust the position of the extrusion roller 552 to achieve the effect of adjusting the ingredients of different pumping modules. A pin joint 510 is arranged at one end of the conical column 51, and a pin joint 2 530 is arranged at the other end of the cylinder 53, wherein the pin joint 1 510 and the pin joint 2 530 are both provided with a notch that is adapted to the shape of the connecting pin 47, so as to quickly connect and separate the pumping mechanism 4 and the metering and dispensing mechanism 5.

[0028] The use method and working principle of the device are as follows: the paint thinner raw materials are stored in different mixing tanks 3 according to the formula, and each raw material is pumped and mixed by a separate pumping mechanism 4. The pumping mechanism 4 is powered by rotation, and the capacity of the pumped raw materials depends on the rotation speed. The input end is replenished with a fixed amount of raw materials every time it rotates one circle; a quantity distribution mechanism 5 is designed between adjacent pumping mechanisms 4, and its cone column 51 is connected to one pumping mechanism 4 by transmission, and the cylinder 53 is connected to the other pumping mechanism 4 by transmission, and the gap between the two is equal everywhere. The threaded column 52 is rotated to make the threaded sleeve 551 slide, driving the key shaft sleeve 553 to move, and controlling the transmission of the cylinder 53 and the cone column 51 at different thickness positions. Because the extrusion roller 552 fits the outer surface of the cone column 51, the cylinder 53 rotates to drive the cylinder 53 to rotate. The dynamic extrusion roller 552 rotates, thereby driving the cone column 51 to rotate. The contact positions of the extrusion roller 552 and the cone column 51 are different in thickness, and the rotation speed of the cone column 51 is different, so that the rotation adjustment of the cylinder 53 is realized, and the pumping ratio of the two pumping mechanisms 4 is controlled; the connecting pin 47 of the pumping mechanism 4 is driven to rotate by the servo motor 6 or the metering and dispensing mechanism 5, and the connecting pin 47 drives the eccentric cylinder 45 to rotate in the cylinder 41. Because the eccentric cylinder 45 is eccentric, the slot 450 and the baffle 46 face different directions of the cylinder 41 when it rotates. The two ends of the baffle 46 are always close to the inner wall of the cylinder 41, and the volume change of the cavity on both sides produces positive and negative pressure, which pumps the raw material on the left to the right, realizing the raw material pumping transportation, and the pumping flow rate is determined by the rotation speed of the connecting pin 47.
