Detailed Embodiments

[0031] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0032] Please refer to Figures 1-4 , the present utility model provides a technical solution: a roll skin mechanism for a pair of roll machines, including a base 1, a conveying assembly 200 installed on the top of the base 1 for feeding and discharging materials, and a processing mechanism 300 installed on the top of the base 1 for processing concrete;

[0033] Through the combined use of the base 1, the main body assembly 200 and the processing mechanism 300, during actual use, when it is necessary to replace the roller skin, there is no need to remove the bearing seat. Just loosen the bolts between the motor and the roller shaft to disassemble the motor and the roller shaft. Thus, it is not necessary to turn a large number of bolts to disassemble the motor, the bearing seat and the roller shaft, and the operation is relatively simple, improving the work efficiency of the staff and enhancing the practicality of the roller skin mechanism of the roller machine.

[0034] In this embodiment, the conveying assembly 200 is a structure for conveying the concrete to be processed.

[0035] As Figure 1 shown, the conveying assembly 200 includes two vertical plates 201 fixed to the top of the base 1, two cross plates 202 respectively fixed to the opposite sides of the two vertical plates 201, and a feeding hopper 203 fixed to the opposite sides of the two cross plates 202.

[0036] It should be noted that a storage tank 204 is provided on the top of the base 1, and a discharge hole 205 is provided on the back of the base 1. The front of the discharge hole 205 is communicated with the storage tank 204 to ensure the effective storage and discharge of the processed concrete.

[0037] In this embodiment, the pair of rollers assembly 301 is a structure for processing concrete.

[0038] As Figure 1 、 Figure 2 and Figure 4 shown, the pair of rollers assembly 301 includes four sliding plates 3011 slidably connected to the top of the base 1, bearing seats 3012 fixed to the tops of the sliding plates 3011 by bolts, two roller shaft bodies 3013 respectively rotatably connected between the inner parts of the two front bearing seats 3012 and between the inner parts of the two rear bearing seats 3012, a motor 3014 fixed to the left side of the roller shaft body 3013 by bolts, and a roller skin body 3015 fixed to the outside of the roller shaft body 3013 by bolts.

[0039] It should be noted that the sliding plates 3011 are fixed to the base 1 by bolts.

[0040] In this embodiment, the disassembly and assembly component 302 is a structure for facilitating the replacement of the roller skin.

[0041] As Figure 1 、 Figure 2 and Figure 3As shown in the figure, the disassembly and assembly component 302 includes two first movable blocks 3021 slidably connected inside the base 1, two second movable blocks 3028 fixed to the top of the base 1, four moving blocks 3024 slidably connected inside the first movable blocks 3021 and the second movable blocks 3028 respectively, a limiting rod 3025 slidably connected inside the moving blocks 3024, and a hydraulic rod 3026 fixed to the front of the first movable block 3021.

[0042] It should be noted that an activity groove 3022 is formed at the top of the base 1, and the first movable block 3021 is slidably connected inside the activity groove 3022, making the first movable block 3021 more stable when moving.

[0043] In addition, moving grooves 3023 are formed at the tops of the first movable block 3021 and the second movable block 3028, and the moving blocks 3024 are slidably connected inside the moving grooves 3023, ensuring that the moving blocks 3024 can slide stably and effectively in the moving grooves 3023.

[0044] Furthermore, two fixing grooves 3027 are formed at the top of the base 1, and the second movable block 3028 is fixed inside the fixing grooves 3027, enabling the fixing of the second movable block 3028.

[0045] Meanwhile, the limiting rod 3205 is fixed inside the moving groove 3023, and the bottom of the sliding plate 3011 is fixed to the top of the moving block 3024, fixing the limiting rod 3025 and ensuring that the moving block 3024 can slide stably and effectively in the moving groove 3023, thereby improving the stability of the sliding plate 3011 when sliding.

[0046] The working principle of the above embodiment is as follows:

[0047] During use, add the concrete to be processed into the hopper 203, and then the two roller body 3013 can effectively process the concrete. Moreover, by opening the hydraulic rod 3026, the first movable block 3021 is driven to move back and forth for adjustment, thereby driving the front roller body 3013 to move back and forth for adjustment, so as to effectively adjust the gap between the roller bodies 3013, thus improving the practicability of the mechanism. When the roller skin body 3015 needs to be replaced, first loosen the bolts, remove the motor 3014, and at the same time loosen the bolts to release the sliding plate 3011 and release the fixation of the sliding plate 3011, then the bearing seat 3012 on the left can be moved to the left, and the bearing seat 3012 on the right can be moved to the right. At the same time, under the action of the limit rod 3025 and the moving block 3024, the bearing seat 3012 moves more stably, so that the bearing seat 3012 loses the limit on the roller body 3013, and the roller body 3013 can be effectively removed to replace the roller skin body 3015. After the replacement is completed, the bearing seat 3012 is driven to move by moving the sliding plate 3011, so as to realize the limit on the roller body 3013, and then the roller body 3013 and the output shaft of the motor 3014 are fixed by bolts, thus completing the installation. There is no need to separate the bearing seat 3012 from the base 1, so that the process of replacing the roller body 3013 is relatively convenient.

[0048] Compared with the prior art, for this pair of roller machine roller skin mechanism, through the combined use of the base 1, the main body assembly 200 and the processing mechanism 300, during actual use, when the roller skin needs to be replaced, there is no need to remove the bearing seat. Only by loosening the bolts between the motor and the roller shaft can the motor and the roller shaft be disassembled, so that there is no need to loosen a large number of bolts to disassemble the motor, the bearing seat and the roller shaft, and the operation is relatively simple, improving the work efficiency of the staff and the practicability of the pair of roller machine roller skin mechanism, and solving the problem of low practicability of the existing pair of roller machine roller skin mechanism.
