Description

Technical Field

[0001] This utility model relates to the field of raw material proportioning equipment technology, and in particular to a raw material proportioning device for adhesive preparation. Background Technology

[0002] An adhesive is a substance that can bond two objects together, achieving a connection through surface adhesion and cohesion. The selection of an adhesive depends on factors such as the material of the objects being bonded, the environment in which they will be used, and the required bond strength. Adhesives have wide applications in daily life and industrial production, such as furniture manufacturing, bookbinding, electronic product assembly, and automobile manufacturing. With technological advancements, the types and performance of adhesives are constantly being improved and enhanced. The production and processing of adhesives requires a raw material proportioning device for adhesive preparation, as follows.

[0003] A search revealed a patent with authorization announcement number CN220609948U, which discloses a formaldehyde-free adhesive raw material proportioning device. This device includes: a base; a fixing rod fixedly connected to the top of the base on one side; a protective box fixedly connected to the top of the fixing rod; a first motor housed inside the protective box; a threaded rod fixedly connected to one end of the first motor; a threaded block threadedly connected to the external thread of the threaded rod; and a fixing plate fixedly connected to one side of the threaded block via two connecting bolts. This formaldehyde-free adhesive raw material proportioning device, through the cooperation of a scraper and a mixing frame, prevents the formaldehyde-free adhesive raw material from sticking to the inner wall of the mixer during mixing, thus ensuring even mixing. Furthermore, the scraper facilitates subsequent cleaning during the material unloading and washing process.

[0004] However, the aforementioned adhesive raw material proportioning device still has the following areas for improvement. For example, although it can improve the uniformity of mixing by scraping off the adhesive raw material on the inner wall of the mixer with the help of the stirring mechanism and scraper, the top of the mixer is open. Therefore, during the mixing process, some dust and impurities in the air may fall into the mixer and mix with the raw material. Some dust and impurities may participate in the chemical reaction of the adhesive, change its chemical properties, and affect its subsequent bonding effect. In addition, dust and impurities may introduce microorganisms, moisture, etc., affecting the storage stability of the adhesive. This will undoubtedly lead to a reduction in the production and processing quality of the adhesive. Therefore, its structure needs to be improved and its practicality needs to be enhanced. Utility Model Content

[0005] This utility model discloses a raw material proportioning device for adhesive preparation. It includes a raw material proportioning and stirring mechanism. During operation, two cylinders in the mechanism are activated and contracted, causing a lifting seat to move downwards. This, in turn, moves the cap downwards until it abuts against the top opening of the mixing tank, sealing the top opening. Then, multiple storage bins, along with their feeding components, deliver the proportioned raw materials to the mixing tank. The raw materials in the mixing tank are then stirred and mixed. During this process, because the cap seals the top opening of the mixing tank, dust and impurities are effectively prevented from entering the mixing tank and mixing into the adhesive, thus significantly improving the quality of adhesive production. In summary, this invention solves the problems in the prior art.

A first scraper and a second scraper are fixedly connected to one side and the bottom of the mounting frame respectively. The first scraper is in contact with the inner wall of the mixing tank. The bottom height of the second scraper is lower than the bottom height of the stirring shaft. Multiple storage boxes are provided, and the bottom of each storage box is provided with a feeding component. The bottom end of the feeding component extends through the cover to the bottom of the cover.

[0009] A clamping mechanism is located in a groove and engages with a cross-shaped clamping slot, and the top of the clamping mechanism is fixedly connected to the bottom of the mixing tank.

[0010] Furthermore, two sets of telescopic guide rods are fixedly connected to the top of the base, and the two sets of telescopic guide rods are respectively close to the two cylinders, and the telescopic ends of the telescopic guide rods are fixedly connected to the bottom of the lifting seat.

[0011] Furthermore, a sealing gasket is fixedly attached to the bottom of the cap. The sealing gasket is made of rubber material, and its position matches the edge of the top opening of the mixing tank.

[0012] Furthermore, the docking slot is a rectangular slot, and the outer surfaces of the docking blocks are all smooth surfaces.

[0013] Furthermore, the mounting mechanism includes a base, a first magnet, and a second magnet. The base matches and engages with the groove, and the top height of the base is higher than the top height of the base.

[0014] Furthermore, the bottom of the base is fixedly connected with multiple positioning support legs, which are matched and engaged with positioning slots, and the bottom height of the positioning support legs is flush with the cross-shaped locking block.

[0015] The present invention has the following advantages over the prior art:

[0016] 1. This technical solution incorporates a raw material proportioning and mixing mechanism. During operation, two cylinders within this mechanism are activated and retracted, causing the lifting seat to move downwards. This, in turn, moves the sealing cap downwards until it abuts against the top opening of the mixing drum, sealing the top opening.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be understood that the terms "surface", "side", "gap", "peripheral", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0029] Reference Figures 1-5 A raw material proportioning device for preparing adhesive includes a base 1 and a mixing tank 2. The top of the base 1 is provided with a groove 3, the bottom of the groove 3 is provided with a cross groove 4, and the bottom of the groove 3 is provided with positioning grooves 5 around the cross groove 4. The mixing tank 2 is located above the base 1. A discharge pipe 6 with a valve is provided at the bottom of one side of the mixing tank 2. Handles 7 are fixedly connected to both sides of the mixing tank 2.

[0030] The raw material proportioning and mixing mechanism 8 includes a cylinder 801, a lifting seat 802, a motor 803, a cover 804, a connecting shaft 805, a mixing shaft 806, a mounting frame 807, and a storage tank 808. Two cylinders 801 are provided, both fixedly mounted on the top of the base 1, and located on opposite sides of the mixing tank 2. The bottom of the lifting seat 802 is fixedly connected to the telescopic ends of the two cylinders 801. The motor 803 is... The motor 803 is fixedly installed on the top of the lifting base 802, and its output end moves through the lifting base 802. The cover 804 is fixedly installed on the bottom of the lifting base 802 by multiple connecting rods 809. The size and shape of the cover 804 match the mixing tank 2. The top end of the connecting shaft 805 is connected to the output end of the motor 803, and the bottom end of the connecting shaft 805 moves through the cover 804 and is rotatably connected to the cover 804. The bottom end of the connecting shaft 805 is fixedly connected to the card seat 810, and the bottom of the card seat 810 has a docking slot 811. The top of the stirring shaft 806 is fixedly connected to the docking block 812, which matches and engages with the docking slot 811. The docking block 812 and the card seat 810 are fixedly connected by locking bolts 813. There are two mounting frames 807, which are fixedly connected to both sides of the stirring shaft 806 respectively. The first scraper 814 and the second scraper are fixedly connected to one side and the bottom of the mounting frame 807 respectively. 815, the first scraper 814 is attached to the inner wall of the mixing tank 2, the bottom height of the second scraper 815 is lower than the bottom height of the mixing shaft 806, multiple storage boxes 808 are provided, and the bottom of each storage box 808 is provided with a feeding component 816, the bottom end of the feeding component 816 extends through the cover 804 to the bottom of the cover 804; the clamping mechanism 9 is located in the groove 3 and engages with the cross groove 4, and the top of the clamping mechanism 9 is fixedly connected to the bottom of the mixing tank 2;

[0031] Two sets of telescopic guide rods 817 are fixedly connected to the top of the base 1. The two sets of telescopic guide rods 817 are close to the two cylinders 801 respectively, and the telescopic ends of the telescopic guide rods 817 are fixedly connected to the bottom of the lifting seat 802. A sealing gasket 818 is fixedly attached to the bottom of the cover 804. The sealing gasket 818 is made of rubber material, and the position of the sealing gasket 818 matches the position of the top opening edge of the mixing tank 2. The docking groove 811 is a rectangular groove, and the outer surface of the docking block 812 is a smooth surface.

[0032] In the specific implementation process, during operation, two cylinders 801 can be activated to retract, causing the lifting seat 802 to move downwards, thereby causing the sealing cover 804 to move downwards until the sealing cover 804 abuts against the top opening of the mixing tank 2, thus sealing the top opening of the mixing tank 2. Then, multiple storage boxes 808, in conjunction with their feeding components 816, can be used to transport the raw materials to the mixing tank 2 in the specified proportions. At this time, the motor 803 can be activated, driving the connecting shaft 805 to rotate, which, in conjunction with the clamping seat 810 and the docking block 812, drives the mixing shaft 806 to rotate, thus mixing the raw materials in the mixing tank 2. During this process, because the sealing cover 804 can seal the top opening of the mixing tank 2, it can effectively prevent dust and impurities from entering the mixing tank 2 and mixing into the adhesive, effectively improving the production and processing quality of the adhesive. In this process, the rotation of the stirring shaft 806 can drive the installation frame 807 to rotate, thereby driving the first scraper 814 and the second scraper 815 to rotate. The first scraper 814 can scrape the inner wall of the mixing tank 2, and the second scraper 815 can scrape the inner bottom surface of the mixing tank 2, thereby preventing the adhesive material from sticking to the inside of the mixing tank 2 and reducing the mixing uniformity. After the adhesive material is mixed according to the ratio, the cylinder 801 can be activated to extend it, driving the lifting seat 802 and the stirring shaft 806 and other components to move upward. When the stirring shaft 806 is completely separated from the mixing tank 2, the locking bolt 813 can be removed, thereby removing the stirring shaft 806 together with the installation frame 807, which facilitates the cleaning of the stirring shaft 806, the installation frame 807, the first scraper 814 and the second scraper 815, and avoids affecting the next use of the device.

[0033] Among them, the telescopic guide rod 817 can improve the overall stability of the lifting seat 802, making the lifting seat 802 less prone to shaking;

[0034] Among them, the sealing gasket 818 can improve the sealing effect of the cap 804 at the top opening of the mixing tank 2;

[0035] The rectangular slot 811 is designed to facilitate rotational transmission with the rectangular docking block 812. Specific Implementation Example 2:

[0037] Reference Figure 5 and Figure 6In a preferred embodiment, the mounting mechanism 9 includes a base 901, a first magnet 902, and a second magnet 903. The base 901 is matched and engaged with the groove 3, and the top height of the base 901 is higher than the top height of the base 1. A cross-shaped locking block 904 is fixedly connected to the bottom of the base 901, and the cross-shaped locking block 904 is matched and engaged with the cross-shaped locking groove 4. A plurality of first magnets 902 are fixedly attached to the top of the base 1, and a plurality of second magnets 903 are fixedly attached to the periphery of the base 901. The second magnets 903 are attracted and connected to the first magnets 902.

[0038] The bottom of the base 901 is fixedly connected with multiple positioning support legs 905. The positioning support legs 905 are matched and engaged with the positioning slots 5, and the bottom height of the positioning support legs 905 is flush with the cross block 904.

[0039] In the specific implementation process, after the mixing and processing of the adhesive raw materials is completed and the stirring shaft 806 is removed, the material inside the mixing tank 2 can be discharged through the discharge pipe 6. After the discharge is completed, the mixing tank 2 can be lifted by the handle 7, which will cause the base 901 to separate from the groove 3, the cross block 904 to separate from the cross slot 4, and the positioning support leg 905 to separate from the positioning slot 5. The mixing tank 2 can be easily and quickly removed, and the mixing tank 2 can be easily and quickly cleaned. This avoids the inability to clean the mixing tank 2 properly due to the limitation of the fixing of the mixing tank 2, the operating space, and the operating angle.

[0040] Among them, the positioning support leg 905 can not only position the base 901 during installation, but also facilitate the stable placement of the base 901 on the ground or other tabletops after the mixing tank 2 and the base 901 are removed together.

[0041] The first magnet 902 and the second magnet 903 can effectively improve the connection stability between the base 901 and the base 1 after the reset base 901 and the mixing tank 2 are installed, thereby improving the connection stability of the mixing tank 2.

[0042] Working Principle: During operation, two cylinders 801 are activated to retract, causing the lifting seat 802 to move downwards, which in turn moves the sealing cover 804 downwards until it abuts against the top opening of the mixing tank 2, sealing the top opening. Then, multiple storage bins 808, along with their feeding assembly 816, deliver the raw materials to the mixing tank 2. At this point, the motor 803 is activated, driving the connecting shaft 805 to rotate. This, in conjunction with the clamping seat 810 and the docking block 812, drives the mixing shaft 806 to rotate, mixing the raw materials in the mixing tank 2. During this process, because the sealing cover 804 seals the top opening of the mixing tank 2, dust and impurities are effectively prevented from entering the mixing tank 2 and mixing into the adhesive, effectively improving the production quality of the adhesive. In this process, the rotation of the stirring shaft 806 can drive the installation frame 807 to rotate, thereby driving the first scraper 814 and the second scraper 815 to rotate. The first scraper 814 can scrape the inner wall of the mixing tank 2, and the second scraper 815 can scrape the inner bottom surface of the mixing tank 2, thereby preventing the adhesive material from sticking to the inside of the mixing tank 2 and reducing the mixing uniformity. After the adhesive material is mixed according to the ratio, the cylinder 801 can be activated to extend it, driving the lifting seat 802 and the stirring shaft 806 and other components to move upward. When the stirring shaft 806 is completely separated from the mixing tank 2, the locking bolt 813 can be removed, thereby removing the stirring shaft 806 together with the installation frame 807, which facilitates the cleaning of the stirring shaft 806, the installation frame 807, the first scraper 814 and the second scraper 815, and avoids affecting the next use of the device.

[0043] After the mixing of the adhesive raw materials is completed and the mixing shaft 806 is removed, the material inside the mixing tank 2 can be discharged through the discharge pipe 6. After the discharge is completed, the mixing tank 2 can be lifted by the handle 7, which will cause the base 901 to separate from the groove 3, the cross-shaped locking block 904 to separate from the cross-shaped locking groove 4, and the positioning support leg 905 to separate from the positioning groove 5. This allows for easy and quick removal of the mixing tank 2, enabling convenient and quick cleaning and treatment. This avoids the inability to properly clean the mixing tank 2 due to limitations in fixing the mixing tank 2, operating space, and operating angle.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
