Description

Technical Field

[0001] The utility model belongs to the field of crusher accessory structures, and particularly relates to a roll component gap adjusting device. Background Technique

[0002] In a crusher system, since the material is sheared by the crushing tooth plates in the crushing cavity and punctured. During this process, the two crushing rolls of a double-toothed roll crusher are inevitably subjected to the reaction force given by the material, thereby affecting the roll gap, increasing the discharge particle size, and thus affecting the subsequent washing and screening. Moreover, the crushing teeth are also inevitably worn, thereby causing the roll gap to expand.

[0003] One of the commonly used methods for adjusting the roll gap at present is to connect the bearing seat with a movable steel plate. During the operation of a double-toothed roll internal rotation crusher, it mainly resists the large binding force of the material itself, thus causing an outward expansion force on the double rolls in the reverse direction. Therefore, the main stress point of the movable steel plate is outside the bolt. When the gap needs to be adjusted, the movable steel plate is cut or replaced. This method has high requirements for the crushing teeth. Once the crushing teeth are worn, the movable steel plate needs to be replaced or cut. Replacing requires long-term on-site spare parts for the movable steel plate, and it is difficult to determine the spare part size. Cutting the original movable steel plate will make it difficult to accurately cut the hole specifications, and when adjusting the roll inward, a steel block needs to be inserted and welded at the tail of the long hole. This causes the pulling force of the movable steel plate on the roll component to be not compact, the gap movement is large, and the difference from the target value is large. Although there are also double-roll crushers on the market that adjust the gap through a hydraulic adjustment method, the cost is high. Even when retrofitting on the original equipment, a certain amount of funds need to be invested. Content of the Utility Model

Detailed implementation manners

[0027] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments may be combined with each other.

[0028] The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0029] The present solution discloses a roller component clearance adjustment device, which specifically includes a movable plate 1 and a bearing seat. The bearing seat is a split structure, including an upper seat body 2 and a lower seat body 3. A first adjusting plate 4 is arranged on the side of the bearing seat. The first adjusting plate 4 is inclined and is used in cooperation with the second adjusting plate 12 during use.

[0030] During installation, first, it is necessary to confirm the center distance requirement with the drawing, and use the number of teeth that need to be engaged as confirmed. For example, the designed center distance of the two-tooth roller is 750 mm, and the optimal center distance for the actual crushing effect is 740 mm. It is necessary to adjust the two-tooth roller and the bearing seat 10 mm towards the center, and adjust the single-side roller component 5 mm. Based on the angle design of the teeth of the movable plate 1 and the bearing seat, the number of meshing teeth between the teeth of the movable plate 1 and the bearing seat can be increased. For example, if the bevel angle of the movable plate 1 is designed to be 60°, and each 5 mm is one tooth, then two meshing teeth need to be added to the original number of meshing teeth. After moving the bearing seat to the approximate position, then move the movable plate 1 towards the bearing seat, and then fixedly install the bearing seat cover (i.e., the upper seat body 2). Finally, use the preset suspension ring 7 to hoist and install the movable plate 1, and insert the teeth between the tooth plates from top to bottom.

[0031] During on-site adjustment, first, remove the adjusting bolt used to connect the bearing seat (specifically the lower seat body 3) to the frame, use the crowbar 8 to move the reserved hole 6 part of the bearing seat, confirm the number of meshing teeth according to the actual on-site needs (such as the adjusted roller spacing), adjust the position of the movable plate 1 back and forth, adjust the number of meshing teeth to ensure that the number of meshing teeth on both sides is the same, so as to control the accuracy of the center distance. After the adjustment is completed, tighten the adjusting bolt. A corresponding strip-shaped installation groove is arranged on the frame, and the lower connecting plate 31 is installed on the strip-shaped installation groove by using the adjusting bolt.

[0032] It should be noted that, in actual use, the movable plate 1 is lifted downward from the top by utilizing the lifting ring 7 on the movable plate 1, and the teeth of the second adjustment plate 12 are inserted from the top down into the corresponding teeth of the first adjustment plate 4, thereby completing the meshing / biting between the two, and the setting of the movable plate 1 is utilized to clamp / gather the two bearing seats inward, thereby reducing the pressure borne by the adjusting bolts in the prior art, thereby ensuring a constant spacing between the two roller shafts.

[0033] In order to meet the requirements of different discharge particle sizes, the design of the movable plate 1 and the bearing seat can be adjusted, such as Figure 2 As shown, the tooth-roller gap distance adjustment amount corresponding to each tooth and the total adjustable range or the placement angle of the first adjustment plate 4 and the second adjustment plate 12 can be expanded or reduced, and the fine-tuning requirements of the crushing roller spacing can be met by adjusting the number of teeth meshing between the two tooth plates or the overlapping area between the two tooth plates.

[0034] In the several embodiments provided in the present application, it should be understood that the disclosed methods and systems can be implemented in other ways. For example, the division of the units described above is only a logical function division, and there may be other division methods in actual implementation, such as multiple units or components can be combined or integrated into another system, or some features can be ignored or not executed. The above-mentioned units may or may not be physically separated, and the components displayed as units may or may not be physical units, that is, they may be located in one place, or they may be distributed on multiple network units. Some or all of the units may be selected according to actual needs to achieve the purpose of the embodiment scheme of the utility model.
