Description

Technical Field

[0001] This utility model relates to the technical field of putty roller coating, specifically a putty roller coating machine equipped with an automatic telescopic mechanism. Background Technology

[0002] Existing technologies for putty roller coating mainly include various types of manual tools and mechanical spraying devices. These devices are designed with an emphasis on construction efficiency, coating uniformity, and ease of operation. For putty roller coating, common types include manual rollers and mechanical putty spraying devices.

[0003] Existing putty application methods often involve manual application using a roller, which is inconvenient and causes the putty to settle and solidify over time, affecting its adhesion and usability. To address these issues, a putty roller coating machine disclosed in an existing patent (Chinese patent application number CN202322157950.2, application date 2023-08-11) can be used. This machine allows operators to inject putty, water, and pigment into a container. After injection, the operator can activate a drive motor to rotate a stirring rod. The rotating rod mixes the putty, water, and pigment, and continues to rotate to prevent the putty from settling and solidifying, thus ensuring proper application and usability of the putty.

[0004] Manual scraper rollers are typically made of wood or plastic and covered with short or long nap. They are suitable for applying putty to small areas of walls. The operator rolls the roller to evenly coat the wall with putty, but this method is labor-intensive and slow. Mechanical putty sprayers can significantly improve efficiency, especially for large, flat walls. However, the putty material sprayed by these devices has defects such as a loose surface and insufficient adhesion. This can lead to cracking and peeling during subsequent construction, affecting the overall quality of the work. Furthermore, due to the limitations of the sprayed material, its adhesion to vertical walls or ceilings is difficult to achieve ideal results, further restricting the applicability of mechanical devices.

[0005] Therefore, we proposed that a putty roller coating machine equipped with an automatic telescopic mechanism can effectively solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a putty roller with an automatic telescopic mechanism to solve the problems mentioned in the background art. Currently, manual scraper rollers on the market are usually made of wood or plastic and covered with short or long hair roller sleeves. They are suitable for applying putty to small areas of walls. The operator rolls the roller to make the putty adhere evenly to the wall, but the labor intensity is high and the construction speed is slow. Although mechanical putty spraying devices can significantly improve construction efficiency, especially suitable for large areas of flat walls, the putty material sprayed by this device has defects such as loose surface and insufficient adhesion. This will easily lead to cracking and peeling problems in subsequent construction, affecting the overall construction quality. In addition, due to the characteristics of the sprayed material, its adhesion effect on vertical walls or ceilings is also difficult to achieve ideal results, further limiting the application range of mechanical devices.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a putty roller coating machine equipped with an automatic telescopic mechanism, including a feeding machine, a discharge pipe connected to one side of the feeding machine, and a control component for controlling the operation of the control device electrically connected to the lower end of the feeding machine, the outer end of the discharge pipe passing through the interior of the hollow telescopic rod, the outer top of the discharge pipe being fixedly connected to the inner side of the discharge pipe connecting sleeve, and the outer side of the discharge pipe being fastened to the outer side of the hollow telescopic rod by a set screw; a putty roller assembly is connected to the top of the discharge pipe connecting sleeve.

[0008] As a preferred technical solution of this application, the lower end of the feeding machine is provided with a discharge nozzle, the inner end of which is connected to the discharge pipe. The discharge port serves as a transition structure between the feeding machine and the discharge pipe, allowing the putty material in the feeding machine to be accurately introduced into the discharge pipe, avoiding leakage or accumulation of material at the connection point. At the same time, the clear discharge path ensures the continuity of material transportation, solves the problem of roller coating layer breakage caused by easy interruption of traditional material supply, improves coating integrity, and reduces material waste.

[0009] As a preferred technical solution of this application, the interior of the putty roller assembly includes a roller connecting sleeve connected to the top of the discharge pipe connecting sleeve, and a roller frame fixed to the top of the roller connecting sleeve; a flow guide kit is nested on the outside of the roller frame, and the putty roller core is nested on the outside of the flow guide kit; a roller core cap is set at the left end of the putty roller core; the roller connecting sleeve realizes a stable connection between the putty roller assembly and the discharge pipe joint, ensuring smooth material transfer; each component has a clear division of labor and is easy to disassemble and assemble, and there is no need to disassemble the entire equipment when cleaning or replacing worn parts, reducing maintenance costs; the roller core cap can seal the left end of the putty roller core to prevent material from seeping out from the side, which reduces waste and prevents contamination of the construction wall.

[0010] As a preferred technical solution of this application, the interior of the flow guide kit is provided with several sets of flow guide sleeve outlets at equal angles along its center direction, and the inner side of the putty roller core is provided with several sets of putty roller core outlets. The outer side of the flow guide sleeve outlet corresponds to the inner side of the putty roller core outlet. The corresponding design of the flow guide sleeve outlet and the putty roller core outlet allows the material in the flow guide kit to be evenly distributed to the inner side of the putty roller core, avoiding local accumulation of material and resulting in uneven coating thickness on the roller surface. The outlets distributed at equal angles can further improve the consistency of material distribution, so that the putty forms a uniform coating on the roller surface, solving the problem of loose and cracked coatings in traditional spray coatings and ensuring the quality of roller coating.

[0011] As a preferred technical solution of this application, the inside of the roller frame is a hollow structure, and the outer end of the roller frame is provided with a number of roller connector outlets, which are located inside the flow guide kit.

[0012] As a preferred technical solution of this application, the left end of the flow guiding kit is nested with a flow guiding sleeve cover, and the end edge of the flow guiding sleeve cover is fixedly connected to the flow guiding kit by a self-tapping screw; the flow guiding sleeve cover is fixed by a self-tapping screw, which can achieve a reliable seal on the left end of the flow guiding kit, preventing material from leaking from the left end of the flow guiding kit. At the same time, the self-tapping screw is easy to install and remove, and the internal structure of the flow guiding kit does not need to be damaged when maintaining it later, thus improving the convenience of maintenance.

[0013] As a preferred technical solution of this application, the brush material of the putty roller core is nylon; the nylon brush has good adsorption and wear resistance, which can firmly adsorb putty to form a stable coating, and can withstand long-term roller friction, thus extending the service life of the putty roller core. In addition, the nylon material is not easy to stick to the material, making it easier to clean later.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This putty roller coating machine with an automatic telescopic mechanism continuously supplies material through a feeding machine, and with the adjustable hollow telescopic rod, it can adapt to different working heights; the putty roller assembly has a reasonable structural design, is easy to assemble and disassemble, and has a stable discharge path, ensuring that the putty adheres evenly to the wall surface and avoiding a loose coating. The overall device balances efficient construction and quality assurance, is suitable for both small dead corners and large-area operations, and reduces the difficulty of manual operation and material waste, comprehensively improving the efficiency, adaptability, and economy of putty construction. Specific details are as follows:

[0015] 1. The device far surpasses traditional hand brushes and ordinary roller coatings, and its efficiency can be doubled when multiple units work together. The hollow telescopic rod design for internal material feeding makes the device compact, allowing it to reach deep into architectural corners such as bay windows and entryways to achieve full wall coverage. It also supports crossing ground obstacles and is compatible with various materials such as interior wall putty and latex paint, greatly expanding its applicability to complex construction scenarios.

[0016] 2. The stable discharge structure reduces putty waste, resulting in a material utilization rate significantly higher than traditional construction methods. It also reduces labor input and rework costs caused by cracking and peeling later on. The economic benefits are even more prominent when applied to large-scale projects. In addition, the various components of the putty roller assembly are easy to disassemble and assemble, and the flow guide kit and putty roller core are easy to clean and maintain. Maintenance can be completed without complicated operations, reducing equipment downtime for maintenance and further improving the overall cost-effectiveness of construction and equipment utilization efficiency.

[0024] 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.

[0025] Please see Figures 1-6 The present invention provides the following technical solution: a putty roller coating machine equipped with an automatic telescopic mechanism.

[0026] Example 1: For easier roller coating, please refer to the attached document. Figure 1 -Appendix Figure 3 The system includes a feeding machine 1, with a discharge pipe 2 connected to one side of the feeding machine 1; a control component 7 is electrically connected to the lower end of the feeding machine 1 to realize the operation of the control device; the outer end of the discharge pipe 2 passes through the interior of the hollow telescopic rod 6, the outer top of the discharge pipe 2 is fixedly connected to the inner side of the discharge pipe connecting sleeve 4, and the outer side of the discharge pipe 2 is fastened to the outer side of the hollow telescopic rod 6 by a set screw 3; a putty roller assembly 5 is connected to the top of the discharge pipe connecting sleeve 4; a discharge nozzle 101 is provided at the lower end of the feeding machine 1, and the inner end of the discharge nozzle 101 is connected to the discharge pipe 2.

[0027] Before operation, the start / stop and feeding speed of the feeder 1 can be precisely controlled by inputting the operation command through the control component 7, thereby regulating the overall operating rhythm of the device. The putty material pre-stored in the feeder 1 flows along the inner cavity of the equipment to the pre-set discharge nozzle 101 at the lower end under the drive of its built-in power components such as motors and conveying pumps. The discharge nozzle 101 is sealed to the discharge pipe 2 to form a leak-free material conveying channel, ensuring that the putty enters the discharge pipe 2 stably. The hollow cavity of the hollow telescopic rod 6 is inserted through the outer end of the discharge pipe 2, and the set screw 3 passes through the side wall of the hollow telescopic rod 6 and presses against the outer end of the discharge pipe 2. The wall ensures a rigid connection between the two components, preventing the discharge pipe 2 from shifting due to vibration during material transport or relative displacement between the hollow telescopic rod 6 and the discharge pipe 2 during adjustment, thus ensuring the continuity of material transport. Finally, the material is transported along the discharge pipe 2 to the discharge pipe connecting sleeve 4 fixed at its top, and then transferred from the discharge pipe connecting sleeve 4 to the putty roller assembly 5 connected at the top, providing a continuous material supply for the roller coating operation. Simultaneously, operators can manually or through the drive structure adjust the extension length of the hollow telescopic rod 6 according to the construction scenario. After adjustment, the structure remains stable, ensuring a precise working distance for subsequent roller coating.

[0028] Example 2: This example differs from Example 1 in that it discloses the structure of the putty roller assembly 5 and facilitates automatic telescopic spraying. For details, please refer to the appendix. Figure 1 -Appendix Figure 5The interior of the putty roller assembly 5 includes a roller connecting sleeve 501 connected to the top of the discharge pipe connecting sleeve 4. The roller connecting sleeve 501 is connected to the top of the discharge pipe connecting sleeve 4, and a roller frame 502 is fixed to the top of the roller connecting sleeve 501. A flow guide kit 503 is nested outside the roller frame 502, and a putty roller core 506 is nested outside the flow guide kit 503. A roller core cap 507 is provided on the left end of the putty roller core 506. Several sets of flow guide sleeve outlets 509 are opened at equal angles along the center of the flow guide kit 503 inside, and several sets of flow guide sleeve outlets 509 are opened on the inner side of the putty roller core 506. The dry putty roller core has an outlet 510, and the outer side of the guide sleeve outlet 509 corresponds to the inner side of the putty roller core outlet 510; the roller frame 502 is hollow inside, and the outer end of the roller frame 502 has several sets of roller connector outlets 508, which are located inside the guide kit 503; the putty roller core 506 has a brush made of nylon; the left end of the guide kit 503 is nested with a guide sleeve cap 504, and the end edge of the guide sleeve cap 504 is fixedly connected to the guide kit 503 by self-tapping screws 505.

[0029] Based on Example 1, automatic telescopic spraying and roller coating are further achieved through the putty roller assembly 5: the material is conveyed through the discharge pipe connecting sleeve 4 to the roller connecting sleeve 501 coaxially connected at its top, and flows into the hollow roller frame 502 fixed at the top along the inner cavity of the roller connecting sleeve 501. The hollow structure of the roller frame 502 serves as both a material storage cavity and, through the roller connector discharge port 508 at the outer end, evenly distributes the material to the guide sleeve nested on the outside of the roller frame 502. In component 503, the guide sleeve outlets 509, distributed at equal angles along the center of the circle inside the guide sleeve 503, correspond one-to-one with the putty roller core outlets 510 on the inner side of the putty roller core component 506 nested outside, and their apertures match, which can prevent material blockage or excessive local discharge; after the material passes through the guide sleeve outlets 509 and the putty roller core outlets 510, it penetrates at a uniform speed to the nylon brush layer of the putty roller core component 506, utilizing the high adsorption and elasticity of the nylon material to form on the brush surface. A uniform putty coating is formed. The left end of the guide kit 503 is tightly pressed with the guide sleeve cap 504 by the self-tapping screw 505, forming a sealed cavity at the left end of the guide kit 503, blocking the leakage of material from the gap at the left end of the guide kit 503, and ensuring that all the material flows to the roller core along the outlet 509 of the guide sleeve. The roller core cap 507 at the left end of the putty roller core 506 is interference-fitted with the inner wall of the roller core, which can completely block the path of material seepage from the side of the roller core, avoiding material waste and preventing contamination of the construction wall or equipment. During construction, the operator adjusts to the target working height through the hollow telescopic rod 6, and the structure maintains rigid support after adjustment. Then, the putty roller core 506 is pushed to move along the wall. The friction generated by the contact between the nylon brush and the wall causes the roller core to rotate, completely transferring the uniform putty coating adsorbed on the brush surface to the wall. At the same time, the wear resistance of the nylon brush can ensure that the coating remains flat after long-term construction, avoiding the loosening and peeling problems of traditional spraying.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
