Abstract
Description
Technical Field
[0001] This utility model relates to the field of primer mixing technology, and in particular to a high-speed primer mixer. Background Technology
[0002] Primer is the first layer in a paint system. It improves the adhesion of the topcoat, increases its fullness, provides alkali resistance, and offers corrosion protection. It also ensures even absorption of the topcoat, allowing the paint system to perform at its best. The statement that a high-quality topcoat eliminates the need for a primer is incorrect. Topcoats and primers have different functions. Topcoats focus more on the final decorative and aesthetic effect, while primers prioritize improving adhesion, corrosion protection, and alkali resistance.
[0003] In the production process of primer, the mixing of primer raw materials is a crucial step. To achieve this, a mixer is necessary to assist in the mixing process, ensuring that all primer raw materials are fully and uniformly mixed to meet the required quality standards and process requirements.
[0004] Primers are typically composed of multiple components, some of which may be solid or semi-solid at room temperature and require heating to melt quickly and mix evenly. However, some existing mixers, due to their simple design, lack corresponding heating devices, making it impossible to heat the primer material in a timely and effective manner. This results in the solid components in the primer being difficult to dissolve and disperse quickly, significantly reducing mixing efficiency. Furthermore, in actual production, when the primer is poured into the mixer from a height, the primer generates a significant impact force due to gravitational potential energy under the action of the stirring rod. This impact force acts directly on the bottom of the equipment, causing severe friction between the bottom of the equipment and the supporting components, accelerating wear on the bottom of the equipment, and also causing strong vibration and noise. Therefore, to address these problems, a high-speed primer mixer is proposed. Utility Model Content
[0005] To overcome the above deficiencies, this utility model provides a high-speed primer mixer, which aims to improve the problems of existing mixers lacking heating function and large vibration amplitude during mixing, resulting in severe wear of internal components.

[0010] As a further description of the above technical solution:
[0011] The weight-increasing base has support legs fixedly connected to its four bottom corners. Auxiliary legs are slidably connected to the outside of the support legs. Two gas springs are fixedly connected to the bottom inside of the support legs. Support springs are sleeved on the outside of the gas springs.

[0033] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Reference Figures 1 to 3 This utility model provides an embodiment of a high-speed primer mixer, comprising a weight-adding base 1, which is a hollow metal structure. A drive motor 2 is fixedly connected to the top of the weight-adding base 1, and is also mounted on the right side of the top of the weight-adding base 1. A main gear 3 is fixedly connected to the drive end of the drive motor 2, and is driven by the drive motor 2 to rotate within the inner cavity of the weight-adding base 1. A positioning seat 4 is fixedly connected to the top of the weight-adding base 1, located at the center of the left side of the bottom of the weight-adding base 1, and is used to determine the positions of the mixing rack 5 and the mixing tank 7.
[0035] A mixing frame 5 is rotatably connected to the middle of the positioning base 4. The mixing frame 5 is a round rod in the middle with short mixing blades on the outside of the rod to break up the primer. A curved scraper is provided on the outside to fit the mixing tank 7 and scrape off the primer residue on the inner wall of the mixing tank 7. Inclined arc rods are also provided in front of and behind the curved scraper of the mixing frame 5. The rotating arc rods drive the primer to vortex and rotate, thereby increasing the mixing effect of the mixing frame 5.
[0036] A driven gear 6 is fixedly connected to the bottom of the mixing rack 5. The external teeth of the main gear 3 are meshed with the external teeth of the driven gear 6. The driven gear 6 rotates on the inner wall of the weight-adding base 1 and meshes with the main gear 3, so that the mixing rack 5 fixed by the driven gear 6 can rotate at high speed. A mixing tank 7 is fixedly connected to the top of the positioning seat 4. The mixing tank 7 is used to store the primer material.
[0037] The mixing rack 5 is externally slidably connected to the inner wall of the mixing tank 7. The arc-shaped rod and curved scraper of the mixing rack 5 scrape against the inner wall of the mixing tank 7 to prevent the primer from adhering to the wall. A heating wire 8 is installed inside the mixing tank 7 and is fixed within the inner wall of the mixing tank 7. A temperature controller 9 is installed on the front side of the mixing tank 7. The temperature controller 9 is electrically connected to the heating wire 8. The temperature controller 9 contains a temperature sensor and control circuit, and is connected to the heating wire 8 via a cable to achieve temperature control of the heating wire 8.
[0038] refer to Figure 4 , Figure 5 A telescopic cylinder 10 is installed at the top of the weight-increasing base 1. The telescopic cylinder 10 contains a piston and piston rod, which can extend and retract inside the cylinder. Both ends of the cylinder have connection interfaces for connecting an air source and a push rod 13. The telescopic cylinder 10 has a mounting base on its outer shell for fixing it to the weight-increasing base 1. A sleeve 11 is fixedly connected to the rear exterior of the mixing tank 7. The sleeve 11 is a hollow cylindrical metal tube. A spiral groove 12 is formed on the exterior of the sleeve 11, spiraling upwards. A push rod 13 is rotatably connected to the drive end of the telescopic cylinder 10. The push rod 13 is slidably connected to the inner wall of the sleeve 11, and can move up and down inside the sleeve 11 under the drive of the telescopic cylinder 10.
[0039] A limiting rod 14 is fixedly connected to the outside of the push rod 13. The limiting rod 14 is a short cylindrical metal rod fixed at the middle position of the push rod 13. A return spring 15 is sleeved on the outside of the push rod 13. The return spring 15 is a helical spring. The bottom end of the return spring 15 is fixedly connected to the top end of the sleeve 11, and the top end of the return spring 15 is fixedly connected to the bottom end of the connecting plate 16. The return spring 15 plays a role in assisting sealing and resetting when the heat-sealing cover 17 is closed. When the telescopic cylinder 10 pulls the push rod 13 downward to close the heat-sealing cover 17, the return spring 15 returns to its original state from the stretched state, and pulls the connecting plate 16 and the heat-sealing cover 17 through its elastic force. A sealing assembly is fixedly connected to the top of the push rod 13. The sealing assembly includes a connecting plate 16, the bottom of which is fixedly connected to the top of the push rod 13. A heating sealing cover 17 is fixedly connected to the side of the bottom of the connecting plate 16 away from the push rod 13. The connecting plate 16 serves as the connecting component between the push rod 13 and the heating sealing cover 17. The bottom of the heating sealing cover 17 engages with the top of the mixing tank 7, and the outer side of the limiting rod 14 is slidably connected to the inner wall of the vortex 12. During the mixing process, the heating sealing cover 17 seals the top of the mixing tank 7 to prevent the primer from evaporating and leaking. Simultaneously, its internal heating element works in conjunction with the heating wire 8 inside the mixing tank 7 to improve the heating effect of the primer and accelerate the mixing process. The excellent sealing performance and heating function of the heating sealing cover 17 play a crucial role in ensuring the quality and efficiency of primer mixing.
[0040] refer to Figure 4, Figure 6 The weight-increasing base 1 has four fixed support legs 18 at its bottom corners. Each support leg 18 is a cylindrical metal rod in an inverted T-shape. An auxiliary leg 19 is slidably connected to the outside of each support leg 18. The top of each auxiliary leg 19 has an elastic ring to increase friction when the support leg 18 slides. Two gas springs 20 are fixedly connected to the bottom of each support leg 18, with their tops fixed to the bottom of the support leg 18. The elasticity of the compressed gas inside the gas springs buffers the impact force transmitted by the support leg 18. When the equipment is subjected to vibration, the support leg 18 compresses the gas springs 20, compressing the gas inside and absorbing some energy, thus reducing the impact of vibration on the bottom of the equipment.
[0041] A support spring 21 is fitted around the gas spring 20. The top end of the support spring 21 is fixedly connected to the bottom end of the support leg 18, and the bottom end of the support spring 21 is fixedly connected to the inner wall of the auxiliary leg 19. The support spring 21 and the gas spring 20 work together to further enhance the buffering capacity of the shock-absorbing support structure. When the equipment is subjected to vibration, the support spring 21 and the gas spring 20 are compressed together to absorb and disperse the impact force, thereby improving the shock absorption effect of the equipment. A discharge pipe 22 is fixedly connected to the outside of the mixing tank 7. An open valve 23 is provided in the middle of the discharge pipe 22. The discharge pipe 22 serves as the discharge channel for the mixed primer. Under the control of the open valve 23, the primer in the mixing tank 7 is discharged to an external storage container or subsequent processing equipment.
[0042] Working principle: First, the telescopic cylinder 10 is activated, and the thrust it generates pushes the push rod 13 upward. During this process, because the limiting rod 14 fixed externally to the push rod 13 slides along the inner wall of the swivel groove 12 opened on the outside of the sleeve 11, this structural design causes the push rod 13 to rotate while moving upward. The heating sealing cover 17, which is fixedly connected to the push rod 13 via the connecting plate 16, also rotates synchronously at a 90-degree angle, thereby opening the top of the mixing tank 7. At this point, the operator can place the primer material into the mixing tank 7.
[0043] After the primer material has been placed, the telescopic cylinder 10 is activated again to pull the push rod 13 downward. As the push rod 13 moves downward, the limiting rod 14 slides down along the inner wall of the vortex 12, which in turn drives the push rod 13 to rotate, ultimately causing the heating sealing cover 17 to rotate ninety degrees again, thus covering the top of the mixing tank 7. At the same time, the return spring 15, which was originally in a stretched state, returns to its original state, indirectly applying tension to the heating sealing cover 17 through the sleeve 11, so that the heating sealing cover 17 can seal the top of the mixing tank 7 more tightly, ensuring that the mixing process takes place in a closed environment.
[0044] Next, the temperature controller 9 is activated, which controls the heating wire 8 inside the mixing tank 7 to begin heating. Simultaneously, the heating element inside the heating seal cover 17 also works in conjunction to heat the primer inside the mixing tank 7. Then, the drive motor 2 is activated, and its drive end drives the main gear 3 to rotate. The main gear 3 meshes with the driven gear 6 fixed on the mixing frame 5. The rotation of the main gear 3 is transmitted to the driven gear 6, which in turn drives the mixing frame 5 to rotate at high speed, thoroughly mixing the primer inside the mixing tank 7. Under the stirring action of the mixing frame 5 and the heating action of the heating wire 8 and the heating seal cover 17, the primer gradually melts and eventually reaches a uniformly mixed state.
[0045] Once the primer is mixed, activate the opening valve 23 to open the outlet pipe 22, allowing the mixed primer to be discharged through the outlet pipe 22, thus completing the discharge process.
[0046] During the start-up and operation of the mixer, the high-speed rotation of the stirring frame 5, main gear 3, and driven gear 6 causes vibration in the mixer body. This vibration is transmitted through the weight-adding base 1 to the support legs 18 at its four corners, where the support legs 18 experience sliding friction within the auxiliary legs 19. The gas springs 20 and support springs 21 installed inside the auxiliary legs 19 effectively buffer the impact force transmitted from the support legs 18, thereby dispersing the impact force generated during mixing and protecting the bottom of the equipment from damage. This also reduces noise generated during operation, ensuring stable operation and a comfortable working environment.
[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
