Abstract
Description
Technical Field
[0001] This utility model relates to the field of floor joint cutting technology, specifically a joint cutting device for garage floor paint construction. Background Technology
[0002] Garage floors, especially large-area cement floors such as fine aggregate concrete floors, are prone to cracking during construction and later use due to the internal shrinkage stress of the concrete. To avoid these cracks, one common measure is to cut expansion joints (also known as contraction joints or gaps) in the floor. This can effectively reduce the internal shrinkage stress of the concrete, thereby reducing the probability of cracks appearing on the concrete surface. Therefore, the research and application of floor joint cutting devices are of great significance for improving the construction quality and service life of garage floors.
[0003] However, it still has some drawbacks. For example, most cutting devices cannot freely adjust the depth of the dividing line. Usually, the depth of the dividing line cut by a device is mostly the same, resulting in a low range of applicability. In addition, during the cutting process, the high-speed rotation and friction between the blade and the ground can cause the blade surface temperature to become too high, affecting the life of the blade.
[0004] To address the aforementioned issues, this application proposes a cutting device for garage floor paint application. Utility Model Content
[0005] The purpose of this utility model is to provide a cutting device for garage floor paint construction, in order to solve the problems mentioned in the background art where the cutting device cannot freely adjust the depth of the dividing joint, and the dividing joint depth cut by a device is usually consistent, resulting in a low applicability range of the device and the problem that the blade surface temperature is too high due to high-speed rotation and friction with the ground during the cutting process, which affects the service life of the blade.

[0013] This invention, through the coordinated operation of the connecting block, gear groove, movable block, groove, blade motor, rotating shaft, and adjusting motor and gear in the blade adjustment assembly, allows for adjustments to the cutting depth of the blade during cutting operations without the need to replace the blade. Simply activating the adjusting motor causes the gear to rotate on the gear groove, which in turn drives the movable block to move up and down on the connecting block. This synchronizes the up-and-down movement of the blade motor, rotating shaft, and cutting blade, thereby achieving the effect of adjusting the cutting depth and providing better application prospects.
[0014] This invention utilizes the coordinated operation of a condenser box, inlet, water pipe, and nozzle in a condensation assembly.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Please see Figures 1-4This utility model provides a technical solution: a garage floor paint construction joint cutting device, including a main body 1, a connecting column 2 fixedly connected to the upper outer surface of the main body 1, a cutting blade 3 movably connected to the rear outer surface of the connecting column 2, a blade adjustment assembly 4 fixedly connected to the front outer surface of the connecting column 2, a condensation assembly 5 fixedly connected to the upper outer surface of the main body 1, a dustproof assembly 6 fixedly connected to one side outer surface of the main body 1, a caster wheel 7 fixedly connected to the lower outer surface of the main body 1, a support rod 8 fixedly connected to the upper outer surface of the main body 1, and a handle 9 fixedly connected to one side outer surface of the support rod 8.
[0023] In this embodiment, as Figure 2 As shown, the blade adjustment assembly 4 includes a connecting block 10, a gear groove 11, a movable block 12, a groove 13, a blade motor 14, a rotating shaft 15, an adjusting motor 16, and a gear 17. The connecting block 10 is fixedly connected to the front outer surface of the connecting column 2. A gear groove 11 is fixedly connected to one side outer surface of the connecting block 10. The movable block 12 is slidably connected to one side outer surface of the connecting block 10. A groove 13 is formed on the front outer surface of the connecting column 2. The blade motor 14 is fixedly connected to the front outer surface of the movable block 12. The rear outer surface of the blade motor 14 is fixedly connected to the rotating shaft 15. The adjusting motor 16 is fixedly connected to the rear outer surface of the movable block 12. A gear 17 is fixedly connected to the rear outer surface of the adjusting motor 16. 7. Gear 17 is connected to gear groove 11. Through the cooperation of connecting block 10, gear groove 11, movable block 12, groove 13, blade motor 14, rotating shaft 15, adjusting motor 16 and gear 17 in the blade adjustment assembly 4, if it is necessary to adjust the cutting depth of cutting blade 3 during cutting, there is no need to replace cutting blade 3. Simply start adjusting motor 16. Adjusting motor 16 drives gear 17 to rotate on gear groove 11. Gear 17 drives movable block 12 to move up and down on connecting block 10 in the opposite direction. Thus, blade motor 14, rotating shaft 15 and cutting blade 3 move up and down synchronously to achieve the effect of adjusting cutting depth, bringing better application prospects.
[0024] In this embodiment, as Figure 3As shown, the condensation assembly 5 includes a condensation box 18, an inlet 19, a water pipe 20, and a nozzle 21. The condensation box 18 is fixedly connected to the upper outer surface of the main body 1. The inlet 19 is fixedly connected to the upper outer surface of the condensation box 18. The water pipe 20 is fixedly connected to the upper outer surface of the condensation box 18. The nozzle 21 is fixedly connected to one side of the outer surface of the water pipe 20. Through the cooperation of the condensation box 18, the inlet 19, the water pipe 20, and the nozzle 21 in the condensation assembly 5, when the device is cutting for a long time, the temperature of the cutting blade 3 will be too high. At this time, the condensate in the condensation assembly 5 enters the nozzle 21 through the water pipe 20 and is sprayed out to cool the cutting blade 3, which greatly improves the service life of the cutting blade 3 and brings better application prospects.
[0025] In this embodiment, as Figure 4 As shown, the dustproof component 6 includes a support plate 22, a movable rod 23, a spring 24, a dustproof plate 25, and a wear-resistant pad 26. The support plate 22 is fixedly connected to one outer surface of the main body 1. The movable rod 23 is fixedly connected to the lower outer surface of the support plate 22. A spring 24 is sleeved on the outer wall of the movable rod 23. The dustproof plate 25 is fixedly connected to the lower outer surface of the movable rod 23. The wear-resistant pad 26 is fixedly connected to the lower outer surface of the dustproof plate 25. Through the support plate 22, movable rod 23, and other components in the dustproof component 6... The cooperation of spring 24, dustproof plate 25 and wear-resistant pad 26 ensures that when the device is cutting, the cutting blade 3 will blow dust towards the construction workers, seriously affecting their safety. At this time, the dustproof component 6 can block the dust. Furthermore, due to the action of movable rod 23 and spring 24, the wear-resistant pad 26 under the dustproof plate 25 is kept in close contact with the ground, which better prevents dust from flying. The wear-resistant pad 26 has high wear resistance and can be used for a long time, bringing better application prospects.
[0026] Working principle:
[0027] First, move the device to the site where cutting is required, and then begin cutting. If it is necessary to adjust the cutting depth of the cutting blade 3, there is no need to replace the cutting blade 3. Simply start the adjustment motor 16. The adjustment motor 16 drives the gear 17 to rotate on the gear groove 11. The gear 17 drives the movable block 12 to move up and down on the connecting block 10 in the opposite direction. This causes the blade motor 14, the rotating shaft 15, and the cutting blade 3 to move up and down synchronously, thereby achieving the effect of adjusting the cutting depth. During long-term cutting, the temperature of the cutting blade 3 may become too high. At this time, the condenser in the condensation assembly 5 will condense the condenser. The liquid enters the nozzle 21 through the water pipe 20 and is sprayed out to cool the cutting blade 3, which greatly improves the service life of the cutting blade 3. When the device is cutting, the cutting blade 3 will blow dust towards the construction workers, which seriously affects their health and safety. At this time, the dust can be blocked by the dustproof component 6. Due to the action of the movable rod 23 and the spring 24, the wear-resistant pad 26 under the dustproof plate 25 is in close contact with the ground, which better prevents dust from flying. The wear-resistant pad 26 has high wear resistance and can be used for a long time, bringing better application prospects.
[0028] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
