Description

Technical Field

[0001] The utility model relates to the technical field of measuring scale design, in particular to an automatic weighing module device for liquid materials. Background Art

[0002] Liquid weighing scales are widely used in the manufacturing industry as a device that can weigh the weight of liquid materials. Scientific proportions of materials can be achieved by weighing the materials.

[0003] The publication number of the existing public technology is: CN206074108U. A multi-liquid weight-increasing metering scale includes a metering barrel, which is fixed on a bracket. The cavity in the metering barrel is divided into more than two independent chambers. The lower part of each independent chamber is connected to a discharge pipe through a valve. A barrel cover is arranged above the metering barrel, and the edge of the barrel cover is placed on the bracket. The barrel cover and the upper end of the metering barrel are non-contact matched. More than two ingredient inlets are arranged on the barrel cover above each independent chamber. A weighing module is arranged on the side of the metering barrel on the bracket. The weighing module is connected to a controller. The utility model divides the metering barrel into multiple independent chambers for accommodating different materials, and multiple ingredient inlets are correspondingly opened above each independent chamber. The weighing module is used to weigh the ingredients of each material in turn, so as to realize the proportional weighing of multiple materials, effectively improve work efficiency and reduce costs.

[0004] However, the above patent still has certain disadvantages when in use: it stores the corresponding liquid materials through an independent chamber opened inside and performs weighing operations through a weighing module, but when the weighing is completed and the liquid materials are discharged, part of the liquid materials are easy to adhere to the barrel wall, thereby reducing the discharge volume, resulting in errors in the subsequent material ratio, which is not conducive to better production and use, and the attached materials will not only directly affect the ratio accuracy but also affect the subsequent addition and weighing operations of the liquid materials, and even contaminate the subsequent liquid materials due to long-term retention, thereby causing a decline in the quality of the subsequent products. The overall use effect is not very ideal.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0029] According to an embodiment of the utility model, a liquid material automatic weighing module device is provided.

[0030] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-4As shown, according to an embodiment of the utility model, a liquid material automatic weighing module device includes a bracket 1 and a discharge pipe 25, a metering main barrel 5 is fixedly installed in the middle position inside the bracket 1, a partition 20 is welded in the middle position inside the metering main barrel 5, and accommodating cavities 6 are symmetrically opened on both sides of the partition 20 at the inner position of the metering main barrel 5, and metering secondary barrels 2 are symmetrically formed on both sides of the bottom of the metering main barrel 5. A first scraper assembly 18 is abutted against the inner surface of the metering main barrel 5, and a first slide bar 13 is installed between the first scraper assembly 18. One side of the first slide bar 13 is located at A driving shaft 16 is provided inside the metering main barrel 5, and a second scraper assembly 23 is fixedly installed at the bottom of the driving shaft 16 through the fixed barrel 3. The second scraper assembly 23 abuts against the inner surface of the metering auxiliary barrel 2. Adjustment chambers 21 are symmetrically provided on both sides of the fixed barrel 3. A moving rod 22 is slidably connected to the inner position of the adjusting chamber 21. The moving rod 22 is fixed to the second scraper assembly 23. A spring 4 is installed at one end of the moving rod 22 at the inner position of the adjusting chamber 21. The top position of the metering main barrel 5 is suspended and wrapped with a barrel cover 8. The first sliding rod 13 and the driving shaft 16 are A support rod 7 is symmetrically welded on both sides of the top of the bracket 1, and a top plate 9 is fixedly installed on the top of the support rod 7. A plurality of groups of second cylinders 15 are symmetrically installed on both sides of the top of the top plate 9. A bearing plate 10 is fixedly installed on the top of the second cylinder 15. A brake motor 11 is installed on the top of the bearing plate 10. The output end of the brake motor 11 passes through one side of the bearing plate 10 and is connected to the drive shaft 16. A first cylinder 14 is fixedly installed in the middle of the bottom surface of the top plate 9. A connecting plate 17 is fixedly installed on the bottom of the first cylinder 14. The two ends of the connecting plate 17 The first and second scraper bars 18 are connected to the first and second scraper bars 13 on both sides. The top end of the first scraper bar 13 passes through the top plate 9 and is connected to the anti-slip plate 12 on one side. A slot is provided in the middle of the first scraper bar assembly 18 for the drive shaft 16 to pass through, and the first slide bar 13 is located on the side of the drive shaft 16. This ensures that the first slide bar 13 will not interfere with the operation of the drive shaft 16 when driving the first scraper bar assembly 18 to move. At the same time, due to the offset setting of the first slide bar 13, it is necessary to perform appropriate counterweight operation on one side of the first scraper bar assembly 18 to ensure the stability of the structure.

[0031] In one embodiment, both sides of the barrel cover 8 are welded to the surface of the support rod 7 by metal rods. The barrel cover 8 is suspended and wrapped so that the barrel cover 8 is not directly covered on the metering main barrel 5 in order to avoid the weight of the barrel cover 8 affecting the weighing of the weighing module 19.

[0032] In one embodiment, feed pipes are symmetrically installed on both sides of the top of the barrel cover 8, and the feed pipes are provided to add the required liquid materials.

[0033] In one embodiment, a discharge pipe 25 is fixedly installed at the bottom of the metering sub-barrel 2 , and a solenoid valve 24 is installed on the surface of the discharge pipe 25 .

[0034] In one embodiment, the metering main barrel 5 is a cylindrical structure.

[0035] In one embodiment, the metering sub-barrel 2 is a conical structure, and the conical structure is provided to facilitate the full discharge and use of the liquid material.

[0036] In one embodiment, the surface of the measuring main barrel 5 is located at the top position of the bracket 1 and is surrounded by several groups of weighing modules 19. The weighing module 19 is a new type of sensor application structure, which not only ensures the high precision and good long-term stability of the shear beam sensor, but also solves the problem of weighing error caused by improper installation. It is frequently involved in real life, so it will not be elaborated on. It is connected to an external controller. Through the weighing module 19, the controller and the solenoid valve 24, the self-controlled weighing purpose of the device can be achieved, thereby improving the use effect of the structure.

[0037] In one embodiment, the first scraper bar assembly 18 is composed of arc bars and rectangular bars, and the second scraper bar assembly 23 is composed of arc blocks. Since the metering main barrel 5 is separated by the partition 20 when in use, the internal structure of the metering main barrel 5 becomes a half-arc and half-rectangular structure. Therefore, through the corresponding setting of the arc bars and rectangular bars, the liquid material remaining on the inner wall surface can be scraped off during movement. The second scraper bar assembly 23 is set to ensure that its structure is adapted to the inner wall of the conical structure of the metering sub-barrel 2, so that it can ensure that it can continue to contact the inner wall no matter where it moves to the metering sub-barrel 2, thereby ensuring the cleaning effect of the inner wall of the metering sub-barrel 2 and reducing the residue of liquid material.

[0038] Working principle: In actual use, the corresponding liquid material can be added to the corresponding accommodating chamber 6 through the corresponding feed pipe arranged on the top of the barrel cover 8, so as to facilitate subsequent weighing and use. After the liquid material enters the accommodating chamber 6, the corresponding weighing operation can be performed through the weighing module 19. After the weighing is completed, the solenoid valve 24 corresponding to the position of the discharge pipe 25 can be opened to discharge the liquid material. After the liquid material is discharged, the first slide bars 13 on both sides can be driven to move downward through the ejection operation of the first cylinder 14. At this time, the first scraper assembly 18 at the bottom of the first slide bar 13 can reciprocately scrape the inner wall of the metering main barrel 5. At the same time, the retraction of the second cylinder 15 and the operation of the brake motor 11 arranged on the top can drive the drive shaft 16 to move up and down while rotating, so that the bottom of the drive shaft 16 is connected The second scraper bar assembly 23 can continuously scrape the inner wall of the metering sub-barrel 2, and when the second scraper bar assembly 23 moves downward, the compression and reset of the internal spring 4 can drive the moving rod 22 to move forward and backward accordingly, so that the second scraper bar assembly 23 can continuously fit the inner wall of the metering sub-barrel 2, thereby improving the overall processing effect. The overall arrangement of the first scraper bar assembly 18 and the second scraper bar assembly 23 can scrape off the residual liquid remaining after the liquid raw material inside the barrel wall is removed, so that the liquid material can be fully discharged, avoiding the reduction of the actual amount of material used due to the residue, ensuring the material ratio accuracy, and at the same time, removing the residual material can avoid interference with the subsequent addition of material, ensuring the overall use effect, and thereby improving the subsequent weighing accuracy. The device as a whole has the advantages of small weighing interference, less residue, and clean barrel wall.
