Description

Technical Field

[0001] The utility model belongs to the field of counterweight of liquid materials, and particularly relates to a rotating disc inner core assembly. Background Art

[0002] The basic principles of various car paints, paints, latex paints and inks are to mix various colorants and auxiliary materials according to a formula, and finally obtain the required coating. In the current coating preparation process, in addition to the traditional manual preparation by paint formulators, there are also various types of paint preparation equipment. The paint preparation equipment generally includes a plurality of colorant barrels and a batching conveying module. The batching conveying module discharges the colorants in different colorant barrels respectively according to the formula, and mixes them in a relevant container to obtain the required coating.

[0003] In the process of accurately preparing solutions industrially, there are two common batching devices. One is to arrange nozzles respectively connected to different raw materials above a conveyor belt assembly line. When the material buckets are driven by the conveyor belt to pass through these nozzles in turn, the nozzles inject the required materials into the material buckets according to the controller. Limited by the size of the material bucket nozzle and the type of raw materials, this material device requires a large site. The other is to arrange a plurality of nozzles in a circular layout above a fixed material receiving position. When the material receiving bucket reaches below these nozzles, the opening mechanism of the nozzle (usually a cylinder cooperating with the nozzle pull rod) pulls the valve core pull rod of the nozzle, so that the corresponding nozzle is in an open state, and the nozzle can spray out the corresponding liquid raw material. In the existing second type of industrial preparation mechanism, each nozzle valve needs to be equipped with a set of opening mechanisms, which greatly increases the manufacturing cost. On the other hand, after each valve injects the liquid, it is also necessary to prevent dripping of the residual liquid of this valve to improve the preparation accuracy. Summary of the Invention

[0022] The technical solution of the present utility model will be clearly and completely described below in conjunction with the drawings and specific embodiments. As Figures 1-4As shown in the figure, a rotating disk inner core assembly includes a valve body fixing plate 8, on which at least two valve bodies 9 are arranged along the circumference of at least one concentric circle. The valve body 9 includes a pull rod head 93 that moves up and down to open or close the discharge port of the valve body 9; a clamping mechanism is arranged on the pull rod head 93 to switch between loosening the pull rod head 93 and clamping the pull rod head 93; above the valve body fixing plate 8, the clamping mechanism that is driven to rotate by a rotary drive mechanism and driven to move up and down by a linear drive mechanism is provided; each pull rod head 93 of the concentric circle corresponds to one clamping mechanism. There are various clamping mechanisms. It can be that two clamping plates are driven by a cylinder or the like to approach or move away from each other to clamp and loosen the pull rod head 93; it can also be in the shape of a portal or a hook. Structures such as moving upward to pull the pull rod head 93 to open, moving downward to pull the pull rod head 93 downward or the pull rod head 93 automatically resetting under the action of a spring or the like are all within the protection scope of the present invention. The rotary drive mechanism drives the linear drive mechanism to rotate, and the clamping mechanism is arranged below the linear drive mechanism. Or the linear drive mechanism drives the rotary drive mechanism to move up and down, and the rotary drive mechanism drives the clamping mechanism to rotate. Or the linear drive mechanism drives the clamping mechanism to move up and down, and the rotary drive mechanism drives the clamping mechanism to rotate. All of these several schemes are within the protection scope of the present invention.

[0023] Above the valve body fixing plate 8, a rotating disc 4 driven to rotate by a rotary drive mechanism is provided. The clamping mechanism is slidably arranged up and down below the rotating disc 4 and rotates together with the rotating disc 4. Above the valve body fixing plate 8, a linear drive mechanism is also fixedly provided. The lower end of the linear drive mechanism is rotatably connected to the clamping mechanism and drives the clamping mechanism to move up and down. The lower end of the linear drive mechanism is directly below the rotation center position of the rotating disc 4, and there is no interference between the rotation center position of the rotating disc 4 and the linear drive mechanism. In fact, the linear drive mechanism can be fixedly arranged on the rotating disc 4 and rotate with the rotating disc 4, and the lower end of the linear drive mechanism is fixedly or rotatably connected to the clamping mechanism. For the structure where the linear drive mechanism is fixedly arranged on the rotating disc 4, the linear drive mechanism can be arranged at the center position of the rotating disc 4 or at other positions. However, in the actual working process, firstly, the error of the moving object is large, which will affect the accuracy. Secondly, precision components, such as cylinders in the linear drive mechanism, are prone to failure and affect the service life of the cylinder when rotating frequently, and the accuracy will also be affected. In the present utility model, a linear drive mechanism with a fixed upper end that does not rotate with the rotating disc 4 is preferably adopted. The clamping mechanism rotates with the rotating disc 4, and the lower end of the linear drive mechanism is rotatably connected to the clamping mechanism, which can realize lifting the clamping mechanism without rotating with the clamping mechanism. Here, the shape of the rotating disc 4 can be disc-shaped or other shapes, as long as it can drive the clamping mechanism to rotate together. In the present utility model, multiple valve bodies 9 distributed concentrically only need the same valve body 9 opening mechanism to realize the opening and closing of all valve bodies 9, with a simple structure and low cost.

[0024] Above the valve body fixing plate 8, an inner core fixing plate 1 is fixedly provided. The rotary drive mechanism is fixedly provided on the inner core fixing plate 1, and the rotating disc 4 is driven to rotate by the rotary drive mechanism and arranged on the inner core fixing plate 1. The upper end of the linear drive mechanism is fixedly provided on the inner core fixing plate 1. At least one guide post 10 is fixedly provided downward from the rotating disc 4, and the clamping mechanism is slidably arranged on the guide post 10. The upper end of the linear drive mechanism is fixedly provided on the inner core fixing plate 1. In fact, the rotating disc 4 can be arranged at the upper end or the lower end of the inner core fixing plate 1. If the rotating disc 4 is arranged at the upper end of the inner core fixing plate 1, as long as its size exceeds the inner core fixing plate 1, the support column 7 is located in the area outside the inner core fixing plate 1. If the rotating disc 4 is arranged at the lower end of the inner core fixing plate 1, the rotating disc 4 needs to avoid the position of the linear drive mechanism. The lower end surface of the rotating disc 4 is fixedly connected to the downwardly extending guide post 10.

[0025] The sliding disk lifting plate 11 on the guide post 10, the lower end of the linear drive mechanism is rotatably connected to the disk lifting plate 11; the clamping mechanism includes a disk hook 12 provided on the disk lifting plate 11, and each concentric valve body's pull rod head corresponds to a disk hook 12. When the disk hook 12 is lifted, it hooks the pull rod head 93; the connecting lines between the pull rod heads 93 of each valve body 9 and the center of the concentric circles do not coincide with each other. The shape of the disk lifting plate 11 is not limited to a disk shape, and it can also be other shapes, such as a long strip shape, etc. The disk lifting plate 11 is sleeved on the guide post 10, and the inner wall of the guide hole opened on the disk lifting plate 11 is slidably connected to the outer wall of the guide post 10. Relative linear motion can occur between the disk lifting plate 11 and the guide post 10 in the vertical direction. The valve body 9 includes a body 91 and a valve rod 92, and the pull rod head 93 is provided at the top of the valve rod 92. The valve body 9 is a three-section valve body 9, that is, there are three flow injection modes, and this kind of valve body 9 is prior art, and its structure will not be described in detail here. Each valve body 9 is connected to a liquid pigment. The valve rod 92 is located above the valve body fixing plate 8. By pulling up the valve rod 92 of a valve body 9, the channel inside the valve body 9 can be opened, so as to accurately inject a liquid pigment. The shape of the pull rod head 93 can be a disk shape, and the disk hook 12 can be provided on the lower end surface or side surface of the disk lifting plate 11 to hook the pull rod head 93. The shape of the disk hook 12 can be a door-shaped frame. By rotating, the disk-shaped pull rod head 93 can be located inside the disk hook 12. In this state, by providing an upward pulling force to the disk hook 12, the channel inside the valve body 9 can be opened. According to the shape of the pull rod head 93, disk hooks 12 of different shapes can be set. If the valve bodies 9 on the valve body fixing plate 8 are evenly or unevenly distributed on two or more concentric circles with different diameters, it is necessary to make corresponding adjustments to the setting method of the valve bodies 9 and the shape of the rotating disk 4 hooks. For example, the pull rod heads 93 of the valves on two concentric circles are arranged in a staggered manner, that is, they are not arranged on the same radius; one disk hook 12 is provided for each concentric circle so that it can cooperate with the valve bodies 9 on different concentric circles respectively, and thus different valve bodies 9 can be opened.

[0026] The inner core fixing plate 1 and the valve body fixing plate 8 are connected by support columns 7; the rotation driving mechanism includes a driving gear 6 driven by a driving motor 5 arranged on the inner core fixing plate 1 and a large gear meshing with the driving gear 6. A fixing shaft 2 is arranged downward at the center position of the inner core fixing plate 1. The large gear is rotatably arranged on the fixing shaft 2 through a slewing bearing 3. The rotating disc 4 is fixedly connected with the large gear; the rotating disc 4 is rotatably arranged on the fixing shaft 2; the lower end of the fixing shaft 2 is fixedly provided with the linear driving mechanism. The lower end of the fixing shaft 2 extends below the slewing bearing 3. The large gear and the rotating disc 4 can be integrally arranged as the same part, that is, external teeth are arranged on the outer circumference of the rotating disc 4 to form the large gear. Or they can be two parts fixed together. For example, the rotating disc 4 is fixedly arranged at the lower end of the large gear. In the attached drawings of the present invention, they are integrally arranged. The inner core fixing plate 1 is fixed above the valve body fixing plate 8 through a support rod. Of course, it can also be fixed above the valve body fixing plate 8 in other ways.

[0027] The lower end of the fixing shaft 2 is fixedly connected to a cylinder base 13. The linear driving mechanism includes at least one linear telescopic cylinder 14 arranged in series from top to bottom on the cylinder base 13; the number of the linear telescopic cylinders 14 arranged in series is not less than the number of gear positions of the valve. For a valve without gear positions and only having two states of opening and closing, only one linear telescopic cylinder 14 can be used. In the attached drawings, the valve has three gear positions in the open state, corresponding to different flow rates respectively. Three linearly connected linear telescopic cylinders 14 are connected to the cylinder base 13 from top to bottom in sequence. The cylinder rod of the lowermost linear telescopic cylinder 14 is rotatably connected to a disc lifting plate 11. The up-and-down movement of the disc lifting plate 11 is driven by the telescopic movement of the linear telescopic cylinder 14, and then the internal passage of the valve body 9 is opened through a disc hook 12 on the disc lifting plate 11. Since the disc lifting plate 11 needs to rotate when different valve bodies 9 are opened to ensure the cooperation between the disc hook 12 and different valve bodies 9, if the linear telescopic cylinder 14 also rotates together at this time, the service life of the linear telescopic cylinder 14 will be greatly shortened. Therefore, a boss bolt 15 is arranged on the cylinder rod of the lowermost linear telescopic cylinder 14, and a through hole is arranged on the disc lifting plate 11. The through hole is processed or installed in a stepped shape. The bolt surface of the boss bolt 15 cooperates with the through hole on the disc lifting plate 11 in the vertical direction, but in the horizontal direction, the outer circular surface of the boss bolt 15 does not contact the inner circular surface of the through hole, so as to ensure that while the vertical tension is transmitted between the cylinder rod of the linear telescopic cylinder 14 and the disc lifting plate 11, the linear telescopic cylinder 14 is also ensured not to rotate following the disc lifting plate 11, and the service life of the linear telescopic cylinder 14 is guaranteed.

[0028] The outlets of all valve bodies 9 are arranged below the valve body fixing plate 8 along the circumference of at least one concentric circle; the same rotary drip outlet disc 18 coaxial with the clamping mechanism and rotating synchronously is arranged below the outlets of all valve bodies 9, and the outlet of the rotary drip outlet disc 18 is connected to the material receiving bucket; a feed port 19 is arranged at the upper end of the rotary drip outlet disc 18, and all the outlets of the valve bodies 9 on a concentric circle correspond to one feed port 19; the size of each feed port 19 can only receive the outlet of one valve body 9, and when the clamping mechanism rotates to the position of the pull rod head 93 of the valve body 9, the feed port 19 corresponding to the concentric circle rotates to the bottom of the outlet of the same valve body 9. A material receiving bucket is arranged below the outlet of the valve body 9. When a valve body 9 is unloaded, a clamping mechanism is required, that is, the disc hook 12 on the disc lifting plate 11 is transferred to the valve stem 92 of the next valve body 9. In the process of transferring the disc hook 12 to the next valve body 9, there may be some residual drops left at the outlet of the valve body 9 that was unloaded before. The existing receiving bucket weighed by weight closes the outlet of the valve after the weight reaches the standard. If these residual drops fall into the receiving bucket after the weight is sufficient, it will affect the accuracy of the finished product. The rotating drip outlet disc 18 can receive the outlets of all valve bodies 9. There are several concentric valve bodies 9, and there are several feed ports 19. Each feed port 19 corresponds to all valve body 9 outlets corresponding to their respective concentric circles. Each feed port 19 can be moved to the corresponding concentric circle with the rotation of the rotating drip outlet disc 18. Each valve body 9 outlet can be directly below the corresponding valve body 9 outlet, so as to connect the corresponding valve body 9. The size of the feed port 19 only allows one valve body 9 to be unloaded. In this way, the feed port 19 that meets the weight standard rotates with the clamping mechanism, and residual drips will not enter the feed port 19. The weight of the liquid entering the rotating drip outlet plate 18 and the receiving barrel through the feed port 19 is more accurate. There are many ways of synchronous rotation, which can be driven by different driving mechanisms and achieved by adjusting the rotation parameters. The rotating drip outlet plate 18 and the clamping mechanism can also be connected. In addition, the feed port 19 only ensures that the raw materials pass through, and the raw materials are not contaminated on the side walls of the feed port 19 as much as possible, and no pipelines are set under the feed port 19 as much as possible, and the liquid raw materials go directly from the outlet of the valve body 9 to the receiving barrel.

[0029] The size of the feed inlet 19 is larger than the size of the outlet of the valve body; the range corresponding to the outlet of the rotary drip outlet disc 18 is larger than the moving range of its feed inlet 19; a material receiving bucket is arranged below the outlet of the rotary drip outlet disc 18, and the liquid directly falls into the lower material receiving bucket after falling from the feed inlet 19, and the inlet of the material receiving bucket is also larger than the moving range of the feed inlet 19 of the rotary drip outlet disc 18. Here, the moving range of the feed inlet 19 is the range passed through during the rotation of the feed inlet 19. The outlet of the rotary drip outlet disc 18 and the inlet of the material receiving bucket are larger than this range, and the liquid directly falls into the material receiving bucket after entering the feed inlet 19. In fact, the rotary drip outlet disc 18 in the present application is equivalent to a straight pipe connecting the outlet of the valve body 9 and the inlet of the material receiving bucket or a cover for blocking liquid residues. The liquid directly falls into the material receiving bucket after coming out of the outlet of the valve body 9, and during this period, no part of the liquid remains on the side walls of the rotary drip outlet disc 18 and the feed inlet 19, improving the accuracy. Preferably, no communicating pipe is arranged between the outlet of the rotary drip outlet disc 18 and the material receiving bucket to avoid the influence of liquid residues on the pipe on the accuracy; however, when the ranges of both of them are larger than the moving range of the feed inlet, the liquid also directly passes through the feed inlet to the material receiving bucket.

[0030] A drip tray 16 is fixedly arranged below the outlet of all valve bodies 9, and an overflow pipe 17 is arranged on the drip tray 16; the rotary drip outlet disc 18 is arranged above the drip tray 16, and the residual drops dripping from the outlet of the valve body 9 flow onto the plate surface of the rotary drip outlet disc 18 and then flow into the lower drip tray 16. A large hole is arranged at the center of the drip tray 16, and the outlet of the rotary drip outlet disc 18 communicates with the space inside the large hole. Specifically: the size of the large hole can include the area where all the outlets of the valve bodies 9 are located. An outlet hole can be arranged at the bottom of the rotary drip outlet disc 18 or the lower housing can be directly not provided. The material receiving bucket can be located below the position of the large hole. A baffle is arranged at the edge of the large hole to prevent the liquid in the drip tray 16 from flowing into the large hole. The baffle is located within the outlet hole of the rotary drip outlet disc 18.

[0031] A central shaft 20 extending upward is fixedly arranged at the center of the rotating drip outlet disc 18. The central shaft 20 passes through a hole at the corresponding position of the valve body fixing plate 8. A lower bottom plate 21 is fixedly arranged at the upper end of the central shaft 20, and the lower bottom plate 21 is fixed to the guide post 10. Specifically, in order to increase the strength of the device and ensure the stability of the rotation of the central shaft 20, a slewing bearing 3 is arranged between the central shaft 20 and the hole at the center of the valve body fixing plate 8. The upper plate surface of the lower bottom plate 21 is connected to the lower end of the guide post 10. Further, the disc lifting plate 11 and the rotating drip outlet disc 18 rotate synchronously, ensuring that the outlet of one valve faces the feed inlet 19 each time, and the outlets of other valves face the plate surface of the rotating drip outlet disc 18. That is, if there is residual liquid at the outlets of other valves, this residual liquid can directly drip onto the plate surface of the rotating drip outlet disc 18. Here, the plate surface of the rotating drip outlet disc 18 is set to be inclined outward, and this residual liquid flows to the drip receiving disc 16 by its own weight and finally flows out from the overflow pipe 17.

[0032] During specific implementation: When receiving materials, the driving motor 5 is started to drive the driving gear 6 and the rotating disc 4 to rotate. The disc hook 12 arranged on the guide post 10 of the rotating disc 4 rotates to the position of the pull rod head 93 of the corresponding valve body 9. The rotating drip outlet disc 18 and the rotating disc 4 rotate synchronously, and the feed inlet 19 rotates to the lower part of the outlet of the corresponding valve body 9 to prepare for receiving materials. The linear driving mechanism, that is, the linear telescopic cylinder 14, pulls the pull rod head 93 upward to different positions as needed to realize the adjustment of different gears for opening the valve. After receiving materials, the linear telescopic cylinder 14 moves downward to close the outlet of the valve body 9. The rotating disc 4 rotates to other positions for receiving materials from other valves or other operations, and the feed inlet 19 also moves away from the outlet of the valve body 9 where the receiving is completed. The residual liquid dripping from the outlet of the valve body 9 where the receiving is completed drips onto the plate surface of the rotating drip outlet disc 18, flows to the drip receiving disc 16 by its own weight, and finally flows out from the overflow pipe 17.

[0033] The technical features of the above-described embodiments can be combined arbitrarily. As long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification. Without departing from the overall concept of the present invention, according to the technical solution of the present invention and equivalent substitution or change, and several changes and improvements made should also be regarded as the protection scope of the present invention.
