Description

Technical Field

[0001] The utility model relates to the technical field of raw material addition, in particular to a raw material addition device for coating production with synchronous addition of multiple raw materials. Background Technique

[0002] The raw material addition device for coating production is a key component in the coating production process, which can improve production efficiency and product quality. At present, there are various raw material addition devices on the market, but most of them have simple designs and single functions, unable to meet the requirements of efficient and uniform mixing.

[0003] Existing raw material addition devices for coating production usually only have one feed inlet, so different raw materials can only be added in batches. This design results in a slow feeding speed, and the raw materials are prone to blockage during the addition process, affecting production efficiency. For example, Chinese Patent CN219232290U provides a raw material addition device for chemical products, including a support, a storage tank is threadedly connected to the upper end of the support; vertical rod frames are welded to the four sides of the lower end of the support; a movable pressure injection seat structure is supported on the outer wall of the storage tank; an observation window is inlaid on the outer side of the interior of the storage tank, and a scale line is engraved on the observation window to avoid scratching; a flow meter is threadedly connected to the middle part of the lower end of the storage tank; a movable support addition injection pipe structure is installed at the lower end of the flow meter. Through the setting of the movable pressure injection seat structure in the utility model, the piston rod in motion is used to apply pressure to the storage tank, thereby increasing the injection speed and amount of the raw materials.

[0004] The above application also adopts a single feed inlet setting. The single feed inlet design limits the simultaneous addition of multiple raw materials, increasing the production time cost; the problem of raw material blockage occurs frequently, reducing the stability of equipment operation and the quality of coating production. Content of the Utility Model

[0006] To achieve the above object, the utility model provides the following technical solution: A raw material addition device for coating production with synchronous addition of multiple raw materials, including a cylinder body, two symmetrically arranged support feet are fixed on the lower surface of the cylinder body, and a stirring rod for stirring the raw materials is arranged inside the cylinder body;

[0007] A feeding mechanism for anti-blocking addition of raw materials is arranged on the upper side of the cylinder body, and an auxiliary mechanism for improving the stirring effect of the raw materials is arranged inside the cylinder body;

[0008] The feeding mechanism includes a feeding box, a motor, a connecting shaft, a spiral blade, a feeding hopper, and a dispersion table. The feeding box is fixed on the upper surface of the cylinder body. The motor is fixed on the upper surface of the feeding box.

[0013] Furthermore, four connecting sleeves are fixed on the outer side of the stirring rod. On both the left and right sides of each connecting sleeve, a crushing rod is fixed. On the front and back of each crushing rod, a blade is fixed. On the single side of the left and right crushing rods far from the connecting sleeve, the same scraping blade is fixed.

[0014] The beneficial effect of adopting the above further scheme is that by combining the functions of stirring, crushing, and scraping, the efficiency and uniformity of raw material mixing are improved. At the same time, the blockage problem that may occur during the stirring of raw materials is reduced, and the quality and efficiency of coating production are enhanced.

[0015] Furthermore, the auxiliary mechanism includes support seats fixed on the inner walls on both sides of the cylinder body, springs fixed on the upper surfaces of the support seats, support plates fixed on the upper surfaces of the springs, and filter nets fixed inside the support plates.

[0016] The beneficial effect of adopting the above further scheme is that the auxiliary mechanism can not only effectively screen the raw materials, but also, through the elastic action of the springs, reduce the direct impact of the raw materials on the filter nets and extend the service life of the filter nets. At the same time, the designs of the support seats and the support plates also facilitate the replacement and maintenance of the filter nets, ensuring the long-term stable operation of the equipment.

[0017] Furthermore, the auxiliary mechanism also includes two chutes opened on the upper surface of the support plate. A sliding rod is slidably connected in each of the two chutes. Support rods are fixed on the inner walls of the four sides of the cylinder body, and the same diversion plate is fixed at the ends of the support rods far from the inner wall of the cylinder body.

[0018] The beneficial effects of adopting the above further solution are as follows: Through the cooperation of the sliding groove and the sliding rod, a dynamic adjustment mechanism can be provided to adjust the position of the filter screen.

[0019] Furthermore, the two sliding rods are respectively fixed to the bottom ends of the two scraping blades, and the inner walls on both sides of the sliding groove are inclined.

[0020] The beneficial effects of adopting the above further solution are as follows: After the sliding rod slides into the sliding groove, the height of the filter screen increases, and after the sliding rod slides out of the sliding groove, the height of the filter screen decreases to realize the vibration of the filter screen.

[0021] Furthermore, the upper surface of the flow dividing plate is provided with no less than two flow dividing holes, and the flow dividing plate faces the filter screen.

[0022] The beneficial effects of adopting the above further solution are as follows: These flow dividing holes play a role in dispersing the flow direction of the raw materials after the raw materials pass through the filter screen. Through the flow dividing holes, the raw materials can be evenly distributed to different regions or directions, which helps to improve the mixing uniformity of the raw materials.

[0023] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

Specific implementation mode

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1-4 , a raw material adding device for coating production with synchronous addition of multiple raw materials in this embodiment, including a cylinder body 1, two symmetrically fixed support feet 2 on the lower surface of the cylinder body 1, and a stirring rod 3 for stirring the raw materials is arranged inside the cylinder body 1;

[0032] A feeding mechanism 4 for anti-blocking addition of raw materials is arranged on the upper side of the cylinder body 1, and an auxiliary mechanism 5 for improving the stirring effect of the raw materials is arranged inside the cylinder body 1;

[0033] The feeding mechanism 4 is arranged on the upper side of the cylinder body 1, and its main function is to realize the anti-blocking addition of raw materials. The design of the feeding mechanism 4 can reduce or avoid the blockage problem occurring during the addition of raw materials, ensuring that the raw materials smoothly enter the inside of the cylinder body 1. The feeding mechanism 4 includes various components, such as a feeding hopper 45, a screw conveyor or other mechanical devices, to promote the continuous flow of raw materials.

[0034] The auxiliary mechanism 5 is located inside the cylinder body 1, aiming to improve the stirring effect of the raw materials. The auxiliary mechanism 5 includes mechanical components for enhancing the stirring action, such as stirring rods 3, crushing rods 7, blades 8, etc., and a filter screen 54 and other auxiliary devices. These components work together to improve the mixing uniformity of the raw materials, ensuring the quality and efficiency of coating production.

[0035] The feeding mechanism 4 includes a feeding box 41, a motor 42, a connecting shaft 43, spiral blades 44, a feeding hopper 45, and a dispersion table 46. The feeding box 41 is fixed on the upper surface of the cylinder body 1, the motor 42 is fixed on the upper surface of the feeding box 41, one end of the connecting shaft 43 is fixed to the output shaft of the motor 42, the other end is fixed to the dispersion table 46, the spiral blades 44 are fixed on the outside of the connecting shaft 43, and the number of feeding hoppers 45 is four and they are connected and fixed on the outside of the feeding box 41.

[0036] The design of the feeding mechanism 4 takes into account the efficiency of raw material addition and anti-blocking properties. Through the synergistic effect of screw conveyance and the dispersion table 46, it ensures that the raw materials can smoothly enter the cylinder 1 and start the mixing process. At the same time, the design of multiple feed hoppers 45 allows for the synchronous addition of multiple raw materials, which is crucial for improving the efficiency and quality of paint production.

[0037] Among them, the shape of the feed box 41 is a frustum of a cone with a hollow interior, and both its inner wall and the outer side of the screw blade 44 are coated with a Teflon coating.

[0038] It should be noted that the Teflon coating has a certain anti-sticking effect and can prevent material sticking.

[0039] The Teflon coating (usually made of polytetrafluoroethylene PTFE) is widely used in various industrial applications due to its unique non-sticking properties, including raw material addition equipment for paint production. The following are the specific functions and advantages of the Teflon coating in the feeding mechanism 4:

[0040] Anti-sticking: The Teflon coating has a very low coefficient of friction, which means it hardly adheres to other substances. During the paint production process, this can significantly reduce the adhesion of raw materials to the inner wall of the feed box 41 and the outer side of the screw blade 44, thus maintaining the smooth flow of raw materials.

[0041] Corrosion resistance: The Teflon coating can also resist the erosion of various chemical substances, including corrosive substances that may be contained in the paint raw materials. This helps to protect the equipment from damage and extend its service life.

[0042] High temperature resistance: The Teflon coating can withstand relatively high temperatures without losing its properties. During the paint production process, there may be situations that require high-temperature operation, and the Teflon coating can ensure the normal operation of the equipment under these conditions.

[0043] Easy to clean: Due to the non-sticking and smooth nature of the coating, cleaning becomes relatively easy. This helps to maintain the hygiene standards of the equipment and ensure the quality and safety of the paint products.

[0044] Improve efficiency: By reducing the adhesion of raw materials, the Teflon coating helps to improve the efficiency of the entire feeding process and reduce the downtime required for cleaning the adhered raw materials.

[0045] Reduce maintenance costs: Since the coating reduces the wear and tear of the equipment and the frequency of cleaning, it can reduce maintenance costs and repair requirements.

[0046] Among them, the stirring rod 3 is fixed to the lower surface of the dispersion table 46 and is on the same straight line as the connecting shaft 43.

[0047] It should be noted that from the motor 42 to the connecting shaft 43, then to the dispersion table 46 and the stirring rod 3, an efficient stirring and dispersion mechanism is formed.

[0048] Among them, four connecting sleeves 6 are fixed on the outer side of the stirring rod 3. On both the left and right sides of the connecting sleeve 6, a crushing rod 7 is fixed. On both the front and back of the crushing rod 7, a blade 8 is fixed. On the single ends of the left and right crushing rods 7 far from the connecting sleeve 6, the same scraping blade 9 is fixed.

[0049] It should be noted that by combining the functions of stirring, crushing and scraping, the design improves the efficiency and uniformity of raw material mixing. At the same time, it also reduces the blockage problem that may occur during the stirring of raw materials, and improves the quality and efficiency of paint production.

[0050] Among them, the auxiliary mechanism 5 includes support seats 51 fixed on the inner walls of both sides of the cylinder body 1, springs 52 fixed on the upper surfaces of the support seats 51, support plates 53 fixed on the upper surfaces of the springs 52, and filter nets 54 fixed inside the support plates 53.

[0051] It should be noted that the auxiliary mechanism 5 can not only effectively screen the raw materials, but also reduce the direct impact of the raw materials on the filter net 54 through the elastic action of the spring 52, and extend the service life of the filter net 54. At the same time, the design of the support seats 51 and the support plates 53 also facilitates the replacement and maintenance of the filter net 54, ensuring the long-term stable operation of the equipment.

[0052] Among them, the auxiliary mechanism 5 further includes two chutes opened on the upper surface of the support plate 53. A sliding rod 55 is slidably connected in each of the two chutes. Support rods 56 are fixed on the inner walls of the four sides of the cylinder body 1. The same flow dividing plate 57 is fixed at the ends of the support rods 56 far from the inner wall of the cylinder body 1.

[0053] It should be noted that through the cooperation of the chute and the sliding rod 55, a dynamic adjustment mechanism can be provided to adjust the position of the filter net 54.

[0054] Among them, the two sliding rods 55 are respectively fixed to the bottom ends of the two scraping blades 9, and the inner walls of both sides of the chute are inclined.

[0055] It should be noted that after the sliding rod 55 slides into the chute, the height of the filter net 54 increases, and after the sliding rod 55 slides out of the chute, the height of the filter net 54 decreases to realize the jitter of the filter net 54.

[0056] Among them, the upper surface of the flow dividing plate 57 is provided with no less than two flow dividing holes, and the flow dividing plate 57 faces the direction of the filter net 54.

[0057] It should be noted that these diversion holes play a role in dispersing the flow direction of the raw materials after the raw materials pass through the filter screen 54. Through the diversion holes, the raw materials can be evenly distributed to different regions or directions, which helps to improve the mixing uniformity of the raw materials.

[0058] The working principle of the above embodiment is as follows:

[0059] Four feeding hoppers 45 can be used to feed different raw materials simultaneously, avoiding sequential feeding and affecting subsequent stirring. During the feeding process, when the output shaft rotates after the operation of the motor 42, it will drive the spiral blade 44 and the dispersion table 46 to rotate. During the rotation of the spiral blade 44, the material will be pushed downward along with the rotation of the spiral blade 44, which can prevent the clogging of the feeding box 41. After different raw materials enter the inside of the cylinder body 1 through the spiral blade 44, they will contact the rotating dispersion table 46, and the dispersion table 46 will break up the raw materials, which can improve the subsequent mixing effect. The broken-up raw materials are stirred by the stirring rod 3 and the crushing rod 7 on its outer side to complete uniform mixing. During the mixing process, the filter screen 54 is used to filter and discharge the small mixed raw materials downward. At the same time, the blade 8 on the outer side of the crushing rod 7 is used to break up the agglomerated raw materials. During the rotation of the scraping blade 9, it is used to prevent raw materials from remaining on the inner wall of the cylinder body 1. When the scraping blade 9 moves, it will drive the two sliding rods 55 to rotate, and the sliding rods 55 will perform a reciprocating movement in and out of the sliding groove. At this time, the filter screen 54 will vibrate up and down through the spring 52, further improving the screening effect of the filter screen 54. After the screening is completed, the raw materials will contact the diversion plate 57, and the mixed raw materials will be diverted and then converge through the diversion openings on the diversion plate 57 and the gap between the diversion plate 57 and the inner wall of the cylinder body 1, further improving the mixing effect between different raw materials and avoiding subsequent operations of the raw materials.
