Description

Technical Field

[0001] The present application relates to the field of paint mixing equipment, and in particular to an auxiliary material feeding mechanism for paint mixing. Background Art

[0002] Paint contains a variety of ingredients, usually including dye components, film-forming components and diluent components, and the film-forming components and diluent components account for a relatively high proportion. The film-forming components and diluent components are usually stored in a storage tank. A discharge pipe and a discharge valve are provided at the bottom of the storage tank. An electronic scale is provided at the bottom of the discharge port. A receiving barrel is placed on the electronic scale. The discharge valve is opened manually for discharge. When the required weight is displayed on the electronic scale, it is closed to obtain the required mass of raw materials, and then the components are mixed for blending. When the discharge pipe is discharged, manual supervision is required, which consumes manpower and workers cannot do other work, thereby reducing production efficiency. Summary of the invention

[0003] In order to improve production efficiency, the present application provides a mechanism for discharging auxiliary materials for paint mixing.

[0004] The present application provides a paint mixing auxiliary material feeding mechanism, which adopts the following technical solution:

[0005] A material discharging mechanism for paint mixing comprises a discharging pipe, a discharging valve for controlling the resistance of the discharging pipe, a frame, a weighing assembly and a material holding barrel, wherein the weighing assembly comprises a supporting shaft and a balancing bar, wherein the supporting shaft is arranged on the frame, and the length direction of the supporting shaft is horizontal; the center part of the balancing bar is hinged on the balancing bar, the material holding barrel is arranged at one end of the balancing bar, and a placing part is arranged at the other end of the balancing bar, wherein the placing part is for placing a mass block;

[0006] It also includes a controller, a magnetic induction switch, and a leakage valve assembly for controlling leakage of the material holding barrel; a leakage pipe is provided at the bottom of the material holding barrel, and the leakage valve assembly controls the flow resistance of the leakage pipe; a positioning piece is provided on the frame, and both ends of the balance bar are in a horizontal state when the balance bar abuts against the positioning piece;

[0007] The discharge valve is a solenoid valve, and the magnetic induction switch, the discharge valve and the leakage valve assembly are electrically connected to the controller; the magnetic induction switch is arranged on the positioning piece, and the balance bar contacts the magnetic induction switch when it is in a horizontal state, and the magnetic induction switch transmits an electrical signal to the controller, and the controller controls the discharge valve to close, and controls the leakage valve assembly to open to make the leakage pipe leak.

[0008] By adopting the above technical solution, the feeding pipe is connected to the storage tank, the feeding barrel is located below the outlet of the feeding pipe, and a mass block is placed on the placement part. After the feeding pipe discharges the material, the liquid enters the feeding barrel to increase the weight of the feeding barrel. When the weights at both ends of the balance bar are equal, the balance bar is horizontal, so that the required mass of liquid is obtained in the feeding barrel. At this time, the magnetic induction switch receives the signal that the balance bar is horizontal, and transmits the electrical signal to the controller. The controller controls the discharge valve to close, so that the feeding pipe is closed. At the same time, the controller controls the leakage valve assembly to open so that the leakage pipe leaks, and the mixing barrel is placed below the leakage pipe. When the leakage is completed, the leakage valve assembly is controlled to close. At this time, the mass on one side of the feeding barrel is less than the mass on one side of the mass block, so that the balance bar tilts toward the side of the mass block. At this time, the magnetic induction switch transmits a signal to enable the controller to control the feeding valve to open, so that the feeding pipe discharges the material, and this cycle is repeated. It is also possible to connect two auxiliary material feeding mechanisms for paint mixing to two storage tanks so that two components can be quantitatively fed at the same time, and place a mixing barrel under the two material storage barrels so that the two components can be merged into the same mixing barrel after weighing, thereby improving production efficiency.

[0009] The present application scheme stops feeding automatically when the required mass of liquid material is reached, and no personnel supervision is required, which reduces manpower requirements and improves the accuracy of dosage. Personnel can carry out other work, thereby improving the utilization rate of working time and thus improving work efficiency. It can also allow two different components to be quantitatively fed at the same time, and the components of the required weight are collected into the same mixing barrel. The two components do not need to be fed separately, saving feeding time, thereby improving production efficiency.

[0010] Optionally, the leakage valve assembly includes two valve magnets and two electromagnets, the electrical signals of the two electromagnets are connected to the controller, the two valve magnets are slidably arranged on the leakage pipe, the two valve magnets adsorb each other to close the leakage pipe, and the sliding directions of the two valve magnets are away from or close to each other; the two electromagnets are arranged at the ends of the valve magnets away from each other, and the electromagnet adsorbs the two valve magnets away from each other.

[0011] By adopting the above technical solution, after the magnetic induction switch receives the horizontal signal of the balance bar, the controller controls the electromagnet to energize, adsorbs and separates the two valve magnets, thereby opening the leakage pipe, allowing the liquid in the material barrel to leak out, making it easier to discharge the material from the material barrel. After a certain period of time, the electromagnet is turned off, and the two valve magnets are adsorbed to each other, closing the leakage pipe.

[0012] Optionally, the leakage valve assembly also includes a mounting plate, a top surface of the mounting plate is provided with a positioning groove for the leakage pipe to enter, the positioning groove is expanded, a side groove for the valve magnet to slide is provided at a relative position of the side wall of the positioning groove, the electromagnet is fixed in the side groove, and a guide slope is provided on the side groove near the top surface of the mounting plate and near the edge of the positioning groove, and the guide slope is inclined upward in the direction close to the positioning groove.

[0013] By adopting the above technical solution, when the electromagnet is just closed, the two valve magnets are far away from each other and difficult to adsorb to each other. By setting the guide slope, when the material barrel is tilted upward, the valve magnets are guided by the guide slope and approach each other, which makes it convenient for the two valve magnets to adsorb to each other and ensure the successful closure of the leakage tube.

[0014] Optionally, edges of the ends of the valve magnets that are away from each other and close to the top surface of the mounting plate are provided with chamfers having the same inclination as the guide slope.

[0015] By adopting the above technical solution, the contact area is increased, so that the valve magnet is not easy to scratch the guiding inclined surface, and the guiding stability is also improved.

[0016] Optionally, sealing rubber strips are provided at the ends of the two valve magnets that are close to each other.

[0017] By adopting the above technical solution, the sealing performance of the two valve magnets when they are attracted to each other is improved.

[0018] Optionally, the inner bottom wall of the material holding barrel is inclined downward toward the center of the bottom of the material holding barrel.

[0019] By adopting the above technical solution, it is convenient for the material container to leak liquid.

[0020] Optionally, the positioning member includes a positioning plate and a positioning block, the positioning block is located above the end of the balance bar where the placement portion is provided, and the magnetic induction switch is provided on the positioning block.

[0021] By adopting the above technical solution, the positioning block positions the positioning plate in a horizontal position and provides an installation position for the magnetic induction switch, making the installation of the magnetic induction switch convenient.

[0022] Optionally, the placement portion includes a connecting rod and a placement plate, the top end of the connecting rod is hinged to the end of the balance rod, the bottom end of the connecting rod is fixed to the center of the placement plate, and the mass block is a weight.

[0023] By adopting the above technical solution, the setting of the connecting rod and the placement plate makes it convenient to place the weight and to match the weights sold on the market.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 2. The electromagnet and valve magnet are convenient for controlling the opening and closing of the leakage pipe;

[0027] 3. The setting of the guide slope ensures that the two valve magnets are successfully adsorbed to each other, so that the leakage pipe is successfully closed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The present application is further described in detail below with reference to the accompanying drawings and embodiments.

[0033] The embodiment of the present application discloses a feeding mechanism for auxiliary materials used in paint mixing. Figure 1 , Figure 2 The auxiliary material feeding mechanism for paint mixing includes a feeding pipe 1, a feeding valve 2, a frame 3, a weighing assembly 4 and a material holding barrel 5. The feeding pipe 1 is used to be connected to the bottom of the storage tank 11, the feeding pipe 1 is used to feed the material to the discharge pipe, and the feeding valve 2 controls the resistance of the feeding pipe 1, thereby controlling the feeding.

[0034] Reference Figure 1 The weighing assembly 4 includes a support shaft 41 and a balance bar 42. The support shaft 41 is fixed to the frame 3, and the length direction of the support shaft 41 is horizontal. The center of the balance bar 42 is hinged to the balance bar 42, and the middle of the length direction of the balance bar 42 is hinged to the balance bar 42. The material barrel 5 is fixed to one end of the balance bar 42 by a connecting rope, and the other end of the balance bar 42 is provided with a placement portion 43, and the placement portion 43 is for placing the mass block 44. When there is no liquid in the material barrel 5, both ends of the balance bar 42 are in a horizontal state.

[0035] Reference Figure 1The placement portion 43 includes a connecting rod 431 and a placement plate 432. The top end of the connecting rod 431 is hinged to the end of the balance rod 42. The placement plate 432 is a circular plate. The bottom end of the connecting rod 431 is welded and fixed to the center of the placement plate 432. The mass block 44 is a weight sold on the market.

[0036] Reference Figure 1 , Figure 3 The auxiliary material feeding mechanism for paint mixing also includes a controller (not shown in the figure), a magnetic induction switch 7, and a leakage valve assembly 8 for controlling the leakage of the material barrel 5. A leakage pipe 51 is integrally formed at the bottom of the material barrel 5, and the inner bottom wall of the material barrel 5 is tilted downward toward the center of the bottom of the material barrel 5, so that the material liquid in the material barrel 5 can easily enter the leakage pipe 51.

[0037] Reference Figure 1 , Figure 3 The leakage valve assembly 8 controls the flow resistance of the leakage pipe 51. The leakage valve assembly 8 includes a mounting plate 83, two valve magnets 81 and two electromagnets 82. The two electromagnets 82 are electrically connected to the controller. The two valve magnets 81 are slidably connected to the leakage pipe 51. The two valve magnets 81 are mutually attracted to close the leakage pipe 51. The sliding direction of the two valve magnets 81 is horizontal, and the two valve magnets 81 slide away from or close to each other.

[0038] The top surface of the mounting plate 83 is provided with a positioning groove 831 for the leakage pipe 51 to enter, and the positioning groove 831 is expanded to facilitate the leakage pipe to enter the positioning groove 831. The side wall of the positioning groove 831 is provided with a side groove 8311 for the valve magnet 81 to slide, and the electromagnet 82 is fixed in the side groove 8311.

[0039] Reference Figure 3 When the leakage pipe 51 is located in the positioning groove 831, the two electromagnets 82 are located at the ends of the valve magnets 81 that are away from each other, and there is a gap between the electromagnets 82 and the valve magnets 81. After the electromagnets 82 are energized, the two valve magnets 81 are attracted to move away from each other, thereby opening the leakage pipe 51. The ends of the two valve magnets 81 that are close to each other are provided with sealing rubber strips 811 to improve the sealing performance when the two valve magnets 81 are attracted to each other.

[0040] A guide slope 832 is provided on the edge of the side groove 8311 close to the top surface of the mounting plate 83 and close to the positioning groove 831, and the guide slope 832 is inclined upward in the direction close to the positioning groove 831. The edge of the ends of the valve magnets 81 that are away from each other and close to the top surface of the mounting plate 83 is provided with a chamfer 812 with the same inclination as the guide slope 832, so that the sliding of the valve magnets 81 is stable. When the two valve magnets 81 move away from the positioning groove 831, the two valve magnets 81 are guided by the guide slope 832 to slide close to each other, so that the two valve magnets 81 are convenient for adsorption to each other.

[0041] Reference Figure 1A positioning member 6 is fixed on the frame 3, and both ends of the balance bar 42 are in a horizontal state when the balance bar 42 abuts against the positioning member 6. The positioning member 6 includes a positioning plate 61 and a positioning block 62. The positioning plate 61 is fixed on the frame 3, and the positioning block 62 is fixed to the bottom surface of the positioning plate 61. The positioning block 62 is located above the end of the balance bar 42 provided with the placement portion 43, and the magnetic induction switch 7 is fixed on the positioning block 62. The magnetic induction switch 7, the unloading valve 2 and the leakage valve assembly 8 are electrically connected to the controller.

[0042] The implementation principle of the auxiliary material feeding mechanism for paint mixing in the embodiment of the present application is as follows: Figure 2 , Figure 3 When in use, the end of the feeding tube 1 is connected to the bottom of the storage tank 11. Before feeding, a weight of corresponding mass is placed on the placement plate 432, so that the material barrel 5 is in an upward state. The feeding valve 2 is opened, the feeding tube 1 discharges the material, and the material liquid enters the material barrel 5. After a certain mass, the mass of the material barrel 5 increases, making the balance bar 42 horizontal. At this time, the magnetic induction switch 7 detects that the balance bar 42 is horizontal, and the electrical signal is transmitted to the controller. The controller controls the feeding valve 2 to close, and at the same time controls the electromagnet 82 to be energized. The electromagnet 82 attracts the two valve magnets 81 away from each other, and the mixing barrel is located below the leakage pipe 51. The material liquid in the material barrel 5 enters the mixing barrel.

[0043] After a certain period of time, the electromagnet 82 is closed, and due to the gravity of the weight, the material container 5 will bend up, so that the leakage pipe 51 slides away from the positioning groove 831. At this time, the two valve magnets 81 slide close to each other through the guide slope 832. After sliding to a certain distance, the two valve magnets 81 attract each other, so that the leakage pipe 51 is closed. When the balance bar 42 loses balance, the magnetic induction switch 7 detects that the balance bar 42 is in an unbalanced state, so that the discharge valve 2 is reopened to discharge the material, thereby repeating the discharge.

[0044] When multiple components need to be mixed, for example, when two components need to be mixed, two auxiliary material unloading mechanisms for paint mixing are connected to two storage tanks 11 containing different components, and the two components are quantitatively unloaded at the same time. A mixing bucket is placed under the two leakage pipes 51, so that the two components are merged into the same mixing bucket after weighing, thereby realizing simultaneous unloading and weighing of the two components and improving production efficiency.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
