Description

Technical Field

[0001] The invention belongs to the technical field of raw material proportioning equipment, and in particular relates to a formaldehyde-free adhesive raw material proportioning equipment. Background Art

[0002] In recent years, the hazards of formaldehyde have received more and more attention. Formaldehyde is a colorless, soluble, irritating gas that is very harmful to the human body. Wooden products made with formaldehyde adhesives used indoors can release formaldehyde for up to 15 years. Formaldehyde-free adhesives are adhesives that do not contain formaldehyde or have extremely low formaldehyde release. They are mainly composed of a variety of environmentally friendly chemicals. The biggest feature of formaldehyde-free adhesives is their environmental performance, which makes them widely used in furniture manufacturing, building decoration and other fields with high environmental protection requirements.

[0003] In the production of formaldehyde-free adhesives, the raw material ratio is crucial to product quality. The raw material ratio equipment includes a metering part, a raw material conveying part, a mixing part and a control system. The metering tank used for raw material ratio works by installing a weighing module at the bottom of the tank. The weighing module can sense the weight changes of the raw materials in the tank in real time. When the raw materials are added to the tank, the weighing block converts the weight signal into an electrical signal and transmits it to the controller. After completing the precise weighing and ratio of the raw materials, the raw materials are transported to mixing equipment such as a high-speed disperser or a high-power stirring kettle through pipes and pumps for the next step of mixing processing to ensure the production of high-quality formaldehyde-free adhesives.

[0004] The weighing module is usually installed under the metering tank by bolts. In the actual production operation process, the weighing module will inevitably fail or have reduced accuracy due to long-term use, overload, environmental factors, etc., and needs to be replaced regularly. At present, in most cases, when replacing the weighing module, the metering tank needs to be moved as a whole. During this replacement process, the following problems may occur:

[0005] 1. Metering tanks do not exist independently in industrial environments. They are usually connected to complex pipeline systems. These pipelines are used for material input, output, and possible circulation operations. The process of moving metering tanks is very likely to cause damage to these connecting pipelines, which may cause leakage of stored or transported materials. In order to avoid damage, if the connected pipelines are disassembled one by one, it will make replacement more difficult;

[0006] 2. If a supporting structure is welded under the metering tank for support, after the welded supporting structure and the metering tank form a whole, the original center of gravity distribution and stress state of the metering tank may be changed, and it is difficult to adjust or disassemble it later.

[0007] In view of the existing structure and deficiencies, improvements are made to provide a formaldehyde-free adhesive raw material proportioning equipment. Summary of the invention

At this time, the protective cover 18 can cover the connecting nut 15 under the action of the spring 21. The protective cover 18 can prevent the connection between the connecting nut 15 and the connecting bolt 14 from contacting with corrosive substances, other impurities, etc., thereby extending the service life of the connecting nut 15 and the connecting bolt 14. At the same time, the support plate 1 7 and the support plate 2 8 are doubly connected with the connecting bolt 14 and the fixing rod 4, thereby improving the stability of the connection between the support plate 1 7 and the support plate 2 8.

When the weighing module 2 is connected to the support frame 1, the protective tube 27 is moved so that the protective tube 27 covers the nut. At this time, the fixing rod 4 rotates so that the fixing rod 4 moves to the upper surface of the short plate 31. At this time, the protective tube 27 cannot move upward. At this time, the nut is covered by the protective tube 27. The protective tube 27 can prevent the nut and the bolt connection from contacting corrosive substances, other impurities, etc., to prevent the nut and bolt from being difficult to disassemble due to corrosion or impurities, thereby reducing the difficulty of disassembly and improving work efficiency.

[0036] Principle of the present invention:

[0037] In the first step, the threaded plate 3 on the support plate 1 7 and the support plate 2 8 is clamped on the outside of the limit block 5 through the limit groove 6. During this process, the pull rope 33 is pulled to drive the short plate 31 to make the protective tube 27 enter the interior of the storage groove 26 so that the threaded plate 3 can be smoothly connected to the limit block 5. When the limit block 5 enters the interior of the limit groove 6, the protective tube 27 is released. At this time, the protective tube 27 slides downward to cover the nut connecting the support frame 1 and the weighing module 2.

[0038] In the second step, at this time, one end of the connecting bolt 14 enters the interior of the protective cover 18 through the opening 16 and the opening 2 17. At this time, the protective cover 18 is pulled to expose the connecting bolt 14. At this time, the spring 21 is stretched. At this time, the connecting nut 15 can be connected to the connecting bolt 14 until the connecting nut 15 fits with the outside of the support plate 1 7. At this time, the protective cover 18 can be loosened. Under the action of the spring 21, the protective cover 18 moves to cover the connecting nut 15. At this time, the fixing rod 4 rotates to connect the fixing rod 4 with the two threaded plates 3. The support plate 1 7 and the support plate 2 8 are connected stably under the double connection of the connecting bolt 14 and the fixing rod 4. The stability is high. When the two ends of the fixing rod 4 are attached to the upper surfaces of the support plates 1 7 and 2 8, the fixing rod 4 is located on the upper surface of the short plate 31. At this time, the short plate 31 is restricted by the fixing rod 4 and cannot move upward. At this time, the protective tube 27 cannot move upward either, thereby ensuring the protective effect of the protective tube 27. At this time, the limiting bolt 11 is rotated to make the limiting bolt 11 and the limiting hole 12 threadedly connected. At this time, the fixing rod 4 is fixed by the limiting bolt 11 and cannot rotate, thereby strengthening the connection between the fixing rod 4 and the threaded plate 3, reducing the risk of the fixing rod 4 being rotated during the disassembly and assembly of the weighing module 2, and ensuring the stability of the supporting mechanism.

[0039] The third step, when the height formed by the bottom plate 19 and the support plate 17 does not meet the working requirements, rotate the fixing bolt 24 to release the connection between the fixing bolt 24 and the fixing hole 25, then move the bottom plate 19 to make the bottom plate 19 fit the ground, then rotate the fixing bolt 24 to connect the fixing bolt 24 with the corresponding fixing hole 25 to fix the bottom plate 19, and then use the same method to adjust the height formed by the bottom plate 210 and the support plate 28. When the weighing module 2 needs to be replaced, rotate the fixing rod 4 in the opposite direction to keep the fixing rod 4 away from the short plate 31. At this time, the protective tube 27 can be moved into the interior of the storage groove 26. At this time, the nut connecting the support frame 1 and the weighing module 2 can be rotated to release the connection between the nut and the bolt. At this time, the connection structure between the weighing module 2 and the placement surface is released, and the weighing module 2 can be taken out from the bottom of the support frame 1.

[0040] Finally, it should be pointed out that the above embodiments are only representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention should be considered to belong to the protection scope of the present invention.
