Description

Technical Field

[0001] This utility model belongs to the technical field of steel coil uncoiling equipment, and in particular relates to an upper and lower uncoiling guide plate platform and a steering roller mechanism assembly. Background Technology

[0002] like Figure 1 The image shows the stainless steel cleaning unit currently used in our factory. This unit was imported from abroad and only includes an upper guide roller 103 suitable for upward uncoiling and an uncoiling steel structure frame 1. This means that when the steel coil 8 is uncoiled and fed into the cleaning machine, it can only operate in the upward uncoiling mode. However, some steel coils 8 require downward uncoiling mode to avoid uncoiling scratches or improve the condition of the steel strip 801 after uncoiling. In this case, the originally designed uncoiling guide plate mechanism cannot meet the actual production requirements.

[0003] Therefore, after removing the existing uncoiling guide table, a new uncoiling guide table mechanism and uncoiling non-powered steering rollers need to be redesigned that can be installed on the existing uncoiling steel structure frame. The design must be able to operate in both upper and lower uncoiling modes, utilize the existing mechanism frame structure and lifting hydraulic system to reduce modification costs, not exceed the existing equipment space, and ensure easy disassembly and assembly for future maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide an upper and lower unwinding guide plate platform and a steering roller mechanism assembly to solve the technical problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: An upper and lower uncoiling guide plate platform and a steering roller mechanism assembly are provided, suitable for a steel structure frame of a cleaning machine equipped with a lifting cylinder. The upper end of the steel structure frame of the cleaning machine is provided with an upper guide roller, including two mounting seats detachably mounted on the steel structure frame of the cleaning machine equipped with a lifting cylinder. A guide roller core is fixed between the two mounting seats. A guide roller sleeve that can rotate around the axis of the guide roller core is fitted on the guide roller core. A guide plate platform connecting block that can rotate around the axis of the guide roller core is provided on the guide roller core at both ends of the guide roller sleeve. The guide plate platform connecting block is connected to the uncoiling guide plate platform. A cylinder connecting block is provided at the bottom of the uncoiling guide plate platform. The cylinder connecting block is connected to the telescopic execution end of the lifting cylinder.

[0006] Preferably, the guide roller core is provided with bearings at both ends, and the guide roller sleeve is fixed on the outer ring of the bearing.

[0007] Preferably, the top surface of the uncoiling guide plate is provided with a guide plate nylon plate, and both ends of the guide plate nylon plate are provided with slopes, the slope of which is close to the guide roller sleeve is matched with the outer diameter of the guide roller sleeve.

[0008] Preferably, a small spacer is provided between the guide roller sleeve and the guide plate platform connecting block, and a large spacer is provided between the guide plate platform connecting block and the mounting base.

[0009] Preferably, the guide plate connecting block includes a connecting plate connected to the uncoiling guide plate and a cover plate fixed to the connecting plate by bolts. Both the connecting plate and the cover plate have semi-circular holes, and the two semi-circular holes are arranged facing each other to form a shaft hole for accommodating a self-lubricating bearing. The self-lubricating bearing is fitted onto the guide roller core.

[0010] Preferably, the steel structure frame is provided with a lower limit top block, and the bottom of the uncoiling guide plate is provided with a buffer platform that matches the lower limit top block. The lower limit top block is used to limit the uncoiling guide plate to the position of the lower uncoiling mode.

[0011] Preferably, an extended nylon guide plate is provided inside the steel structure frame and behind the guide roller sleeve.

[0012] The beneficial effects are as follows: This utility model is used to modify common stainless steel cleaning machines that only have an upper guide roller. By installing the upper and lower uncoiling guide plate platform and the steering roller mechanism provided in this application on the original stainless steel cleaning machine, the guide plate platform can guide steel coils in both the upper and lower uncoiling modes by using the original upper guide roller in combination with the new non-powered guide roller, thereby improving its versatility.

[0013] This utility model can utilize the existing steel structure frame and hydraulic system, which helps to reduce the cost of modification. When maintaining and repairing this application, it is not necessary to disassemble the entire mechanism. Only by disassembling a mounting base can the guide plate system be quickly separated from the frame and cylinder. The uncoiling guide plate can be separated by disassembling the guide plate connecting block. During maintenance, it is not necessary to disassemble the entire mechanism, which improves the efficiency of maintenance and repair of the equipment. Attached Figure Description

[0016] The same markings in each diagram represent the same component. Detailed Implementation

[0017] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0018] like Figure 2 , 3 As shown, this utility model provides an upper and lower uncoiling guide plate platform and a steering roller mechanism assembly, applicable to a steel structure frame 1 of a cleaning machine equipped with a lifting cylinder. The upper end of the steel structure frame 1 of the cleaning machine is provided with an upper guide roller 103. The quick-release upper and lower uncoiling guide plate platform 7 system includes two mounting seats 2 detachably mounted on the steel structure frame 1 of the cleaning machine equipped with a lifting cylinder. A guide roller core 3 is fixed between the two mounting seats 2. A guide roller sleeve 301 that can rotate around the axis of the guide roller core 3 is fitted on the guide roller core 3.

[0019] On the guide roller core 3, at both ends of the guide roller sleeve 301, there is a guide plate platform connecting block 4 that can rotate around the axis of the guide roller core 3. The guide plate platform connecting block 4 is connected to the uncoiling guide plate 7. The bottom of the uncoiling guide plate 7 is provided with a hydraulic cylinder connecting block 702, which is connected to the extension and retraction execution end of the lifting hydraulic cylinder.

[0020] See again Figure 2 The top surface of the uncoiling guide plate 7 is provided with a liner plate, and a guide plate nylon plate 701 is fixed on the liner plate. Both ends of the guide plate nylon plate 701 are provided with slopes, and the slope near the end of the guide roller sleeve 301 matches the outer diameter of the guide roller sleeve 301.

[0021] The steel frame 1 is equipped with a lower limit block 101, and the bottom of the uncoiling guide plate 7 is equipped with a buffer platform that matches the lower limit block 101. The lower limit block 101 is used to limit the uncoiling guide plate 7 to the lower uncoiling mode position. The lower uncoiling mode is limited to a minimum working angle of -34.5°, while the upper uncoiling mode is completely pushed out by the lifting cylinder to limit the working angle to +26.5°.

[0022] In one specific embodiment, this application provides an extended nylon guide plate 102 within the steel structure frame 1, behind the guide roller sleeve 301. To meet the requirement of retaining the original upper guide roller 103 during modification, there is a lack of space to arrange the downward and upward pinch rollers. Furthermore, since the uncoiling tension is lower in the upper uncoiling mode than in the lower uncoiling mode, the steel strip 801 will sag due to its own weight during manual feeding of thick strips. This poses a risk of the strip head getting stuck in the gap during unit operation. This application adds the extended nylon guide plate 102 to prevent the steel strip 801 from getting stuck before tensioning.

[0023] See again Figure 3 A small spacer 5 is provided between the guide roller sleeve 301 and the guide plate platform connecting block 4, and a large spacer 6 is provided between the guide plate platform connecting block 4 and the mounting base 2. By setting the large and small spacers 5, the different directions and different speeds of the guide roller sleeve 301 and the unwinding guide plate platform 7 after coaxial connection can be isolated, and the two can rotate independently without interference on the same shaft.

[0024] like Figure 4 As shown, the guide roller core 3 has bearings 302 at both ends, the guide roller sleeve 301 is fixed on the outer ring of the bearing 302, and the inner ring of the bearing 302 is fixed on both ends of the guide roller core 3. The bearings 302 allow the guide roller sleeve 301 to rotate freely around the axis of the guide roller core 3 under the drive of the unwinding steel coil.

[0025] like Figure 5 As shown, the guide plate connecting block 4 includes a connecting plate 401 connected to the uncoiling guide plate 7 and a cover plate 402 fixed to the connecting plate 401 by bolts 403. Both the connecting plate 401 and the cover plate 402 have semi-circular holes arranged facing each other to form a shaft hole for accommodating the self-lubricating bearing 703, reducing the failure rate and maintenance frequency. The self-lubricating bearing 703 is fitted onto the guide roller core 3, and the self-lubricating bearing 703 can accommodate the slow rotation and lifting of the uncoiling guide plate 7 under the drive of the lifting cylinder. The bolts are custom-made GB / T5782M16X120-12.9 grade high-strength bolts with Dacromet surface treatment.

[0026] This invention is used to modify the steering roller assembly of an existing cleaning machine. It retains the original frame and upper guide roller 103, and modifies the frame based on a newly added mounting base 2. After modification, it can simultaneously meet both upper and lower uncoiling modes of the unit. The overall structure is compact, allowing the modified mechanism to be arranged in a space of less than 2.4m x 1.8m. Utilizing the original steel frame 1 and existing hydraulic system reduces modification costs. This invention improves the efficiency of equipment maintenance and repair. The entire mechanism only requires disassembling one mounting base 2 to quickly separate the guide plate system from the frame and cylinders. Disassembling the guide plate connecting block 4 allows for the separate separation of the uncoiling guide plate 7. Maintenance does not require disassembling the entire mechanism.
