Description

TECHNICAL FIELD

[0001] The utility model relates to the field of organic film-removing liquid, and particularly relates to an automatic metering device for organic film-removing liquid. BACKGROUND

[0002] Organic solvents are a large class of organic compounds widely used in life and production, and have small molecular weight. They exist in coatings, adhesives, paints and cleaning agents. Organic solvents such as styrene, perchloroethylene, trichloroethylene, ethylene glycol ether and triethanolamine can dissolve some organic compounds (such as oil, wax, resin, rubber, dye, etc.) that are insoluble in water. The characteristic is that it is in liquid state at normal temperature and pressure, has high volatility, and the properties of solute and solvent are not changed during the dissolution process.

[0003] The organic film-removing liquid belongs to one of many organic solvents. When the organic solvents are used, they need to be metered for use in proportioning with other materials. Therefore, a metering device is often needed. The conventional metering device can only perform single metering in the actual metering process, that is, after metering is completed, the metered solution needs to be taken out, and the measuring cup needs to be re-placed for metering. The orderly metering operation of multiple measuring cups cannot be realized. Therefore, the metering efficiency is low in the process of facing multiple metering operations. Therefore, we improve it and propose an automatic metering device for organic film-removing liquid. UTILITY MODEL CONTENT

[0004] The utility model aims at providing an automatic metering device for organic film-removing liquid, which solves the problem of low metering efficiency of the existing automatic metering device for organic film-removing liquid during use.

[0005] To solve the above technical problems, the utility model is realized by the following technical schemes:

[0006] An automatic metering device for organic film-removing liquid comprises a support seat, a rotating element is fixed on one side of the top of the support seat, a placing groove is formed on the surface of the rotating element, and a limiting element is arranged at the position close to the placing groove of the rotating element to position the metering element in the placing groove.

[0007] An organic film-removing liquid infusion assembly is arranged above the rotating element, and a weighing element connected with the support seat is arranged below one of the placing grooves.

[0008] As a preferred technical scheme of the application, the rotating element comprises a rotating motor fixedly installed on one side of the top wall of the support seat and a rotating disc connected to the output end of the rotating motor.

[0009] The insertion grooves are arranged on the surface of the rotating disc and are equidistantly distributed in a ring shape.

[0010] The limiting element comprises a movable cavity arranged at the edge of the rotating disc, a servo motor fixed in the movable cavity and a gear connected to the output end of the servo motor.

[0011] The gear is meshed with a toothed plate on one side, and the toothed plate is fixed with a connecting plate at one end.

[0012] The other end of the toothed plate is slidably inserted with a guide plate fixed to the side wall of the movable cavity.

[0013] The metering element comprises a metering cup arranged in the insertion groove, a metering cavity formed in the metering cup and a metering valve arranged at the bottom of the metering cup.

[0014] The outer side of the metering cup is provided with a clamping groove corresponding to the clamping plate.

[0015] The end of the clamping plate is formed with a slope groove.

[0016] The weighing element comprises an electronic scale body arranged on the supporting seat and a weighing platform arranged at the top of the electronic scale body.

[0017] The surface of the rotating disc is fixed with a photoelectric receiver at the position corresponding to the insertion groove.

[0018] The photoelectric receiver, the photoelectric emitter, the rotating motor and the servo motor are electrically connected with the external PLC controller.

[0019] Compared with the prior art, the present application has the following advantages:

[0020] In the scheme of the application: 1. Through the setting of the rotating element, after the single measuring cup is measured, the measured measuring cup can be rotated outside the measuring area under the action of the rotating motor, so that another empty measuring cup is placed above the weighing platform and cooperates with the limiting element to make it fall for measurement, and the above steps can be repeated to orderly realize the measurement of the organic stripping solution in multiple measuring cups. When multiple portions of organic stripping solution are measured, the measurement efficiency of the device can be improved;

[0021] 2. Through the setting of the rotating element, during the measurement of a certain measuring cup, the measuring cup that has been measured and rotated outside the weighing platform can be directly operated outside the measuring valve to discharge the measured organic stripping solution outside for use, so that the measuring cup above the weighing platform can be weighed at the same time without affecting the use of the organic stripping solution in the measured measuring cup, further improving the measurement efficiency of the device.

[0034] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments.

[0035] As shown in Figures 1-6 The present embodiment proposes an automatic metering device for organic film-removing liquid, which comprises a support base 1, a rotating element 2 fixed on one side of the top of the support base 1, a placing groove 21 formed on the surface of the rotating element 2, and a limiting element 3 arranged at the position of the rotating element 2 close to the placing groove 21 for positioning a metering element 4 in the placing groove 21.

[0037] The rotating element 2 comprises a rotating motor 23 fixedly installed on one side of the top wall of the support base 1 and a rotating disc 22 connected with the output end of the rotating motor 23.

[0038] The placing grooves 21 are formed on the surface of the rotating disc 22, and the placing grooves 21 are provided in plurality, the plurality of placing grooves 21 are arranged equidistantly in a ring shape on the surface of the rotating disc 22, and the orderly metering of the plurality of metering cups 41 can be realized through the design of the plurality of placing grooves 21.

[0039] The limiting element 3 comprises a movable cavity 31 formed at the edge of the rotating disc 22, a servo motor 32 fixedly installed in the movable cavity 31, and a gear 33 connected with the output end of the servo motor 32, as shown in Figure 5 A storage battery is installed at the edge of the bottom of the rotating disc 22, the storage battery is electrically connected with the servo motor 32 and the photoelectric receiver 7, and thus the necessary energy can be provided for the servo motor 32 and the photoelectric receiver 7 to meet the normal use.

[0040] The gear 33 is engaged with a toothed plate 34 on one side, one end of the toothed plate 34 is fixedly connected with a connecting plate 35, and the connecting plate 35 is fixedly connected with a clamping plate 36 for clamping the metering element 4 at both ends.

[0041] The other end of the toothed plate 34 is slidingly inserted with a guide plate 37 fixed with the side wall of the movable cavity 31, through the design of the guide plate 37, the stability of the toothed plate 34 in the sliding process is ensured.

[0042] The metering element 4 includes a metering cup 41 located in the insertion groove 21, a metering cavity 42 formed in the metering cup 41, and a metering valve 43 provided at the bottom of the metering cup 41. By opening or closing the metering valve 43, the discharge or retention of organic stripping solution in the metering cup 41 can be formed.

[0043] The outer side of the metering cup 41 is provided with a clamping groove 44 corresponding to the clamping plate 36, and the edge of the bottom of the metering cup 41 is further fixed with a support frame 45, through the design of the support frame 45, the stability of the metering cup 41 and the weighing when the weighing platform 62 is ensured.

[0044] The end of the clamping plate 36 is formed with a relief inclined surface groove 38;

[0045] The weighing element 6 includes an electronic scale body 61 placed on the support seat 1 and a weighing platform 62 located at the top of the electronic scale body 61;

[0046] The bottom of the metering element 4 limited by the limiting element 3 in the insertion groove 21 has a gap between the weighing platform 62;

[0047] The surface of the rotating disc 22 is fixed with a photoelectric receiver 7 corresponding to the position of the insertion groove 21, the surface of the support seat 1 has a photoelectric emitter 71 corresponding to the position of one of the photoelectric receivers 7, the photoelectric receiver 7 is connected with the photoelectric emitter 71, and the rotating action of the servo motor 32 is driven after the photoelectric receiver 7 is connected with the photoelectric emitter 71;

[0048] The photoelectric receiver 7, the photoelectric emitter 71, the rotating motor 23 and the servo motor 32 are all electrically connected with the external PLC controller 8.

[0049] In the actual application process, when the rotating motor 23 drives a certain inserted slot 21 on the rotating disc 22 to rotate above the weighing platform 62, at this time the photoelectric receiver 7 receives the electrical signal of the photoelectric emitter 71, which is fed back to the PIC controller 8, which makes the rotating motor 23 stop (the stop of the rotating motor 23 can be reasonably set in the PIC controller 8 according to the actual perfusion time of the organic membrane-removing liquid), and acts on the servo motor 32 to make it drive the gear 33 to rotate. When the gear 33 rotates, the gear 33 will form a meshing action with the toothed plate 34 on one side, and the toothed plate 34 subjected to the meshing action will drive the clamping plate 36 to slide away from the clamping groove 44 through the connecting plate 35. After the servo motor 32 rotates to the position, it will also stop for a certain period of time (the stop of the rotating motor 23 can be reasonably set in the PIC controller 8 according to the actual perfusion and weighing time of the organic membrane-removing liquid).

[0050] When the clamping plate 36 is separated from the corresponding clamping groove 44, the measuring cup 41 will fall a certain small height and fall on the weighing platform 62. At this time, the organic membrane-removing liquid in the organic membrane-removing liquid perfusion assembly 5 above can be weighed by the electronic scale body 61 (which can be manually closed at this time). When the weight reaches the set weight, the organic membrane-removing liquid perfusion assembly 5 is closed to stop perfusion. At this time, the servo motor 32 still has a remaining time, which can be used to manually remove the excess membrane liquid when the organic membrane-removing liquid is perfused too much. The specific time can be set according to the actual situation. After the servo motor 32 stops for the remaining time, the servo motor 32 rotates in the opposite direction to promote the rotation of the gear 33, so that the gear 33 drives the toothed plate 34 and the clamping plate 36 thereon to slide back to the original position.

[0051] Since the measuring cup 41 will fall a certain small height when the clamping plate 36 is separated from the corresponding clamping groove 44, when the clamping plate 36 slides back to insert into the clamping groove 44, it will form a sliding action with the edge of the clamping groove 44 under the action of the inclined groove 38 at the end of the clamping plate 36 (as shown in Figure 5The rotation motor 23 stops at the time limit, and then the rotation motor 23 continues to rotate until the adjacent photoelectric receiver 7 receives the electric signal of the photoelectric emitter 71 again, at which time the rotation motor 23 repeats the above-mentioned stop time, and so on, so as to realize the orderly infusion of multiple measuring cups. The measuring cup 41 that is conveyed outside the weighing platform 62 after infusion can be discharged through the measuring valve 43, so that the discharge and the measurement are not affected, and the application efficiency of the actual organic stripping solution is effectively saved. The stop time of each link can be set in the PLC controller 8 according to the actual infusion condition, and the action and connection relationship between the PLC controller 8 and each electric device are mature and perfect existing technologies, so further elaboration is not made in the embodiment.

Although the present application has been described in detail with reference to the above embodiments, the present application is not limited to the above specific embodiments, and any modification or equivalent replacement of the present application is included.
