[0002] The double-roll granulator is a molding machine that can make materials into specific shapes. It is widely used in agriculture, medicine and chemical industries, especially in the field of crop fertilizers, where finished products often need to be granulated. For example, in crop production and fertilization, in order to make chemical fertilizers decompose slowly and last longer, auxiliary materials are usually added to the fertilizers for granulation. There are many types of fertilizer granulators, and the double-roll granulator is currently a more commonly used granulation equipment.

[0003] After searching, the Chinese patent with the announcement number CN2184477Y discloses a roller shaft regulator for a compound fertilizer granulator. The driving gear on the driving roller shaft drives the driven gear on the driven roller shaft to make the two roller shafts rotate relative to each other. There are bearing seats and bearings for installing the roller shafts. There is a roller shaft regulator between the bearing seat and the bearing. The so-called regulator is an integrally made regulating disk and an eccentric regulating ring with an eccentric spacing of C = 0.3 to 5 mm. The regulator is fixed by an regulating gland. After installing the regulator, the gap between the two roller shafts can be effectively adjusted at any time without replacing the shaft sleeve, and the structure is simple and easy to install.

[0004] The adjustment grooves are distributed at equal angles around the circumference. In the actual adjustment process, as the adjustment ring rotates, the adjustment spacing of the roller shaft will continue to increase with each subsequent rotation of a certain fixed angle, making it impossible to achieve equal spacing adjustment.

[0027] The following is combined with Figure 1-3 This application is described in further detail.

[0028] A granulation roller spacing regulator, such as Figure 1-Figure 3 As shown, it is used on a granulator 1 to adjust the distance between two granulating rollers 2 of the granulator 1. The granulator 1 includes a main body 3 and two granulating rollers 2 arranged in parallel. The granulating rollers 2 are densely covered with granulating holes 4. The ends of the granulating rollers 2 have transmission gears connecting the two. The granulating rollers 2 include a driving roller and a driven roller. This embodiment is installed at the ends of the driven rollers.

[0029] like Figure 1-Figure 3 As shown, this embodiment includes a bearing end cover 5, an eccentric sleeve 6 and a locking block 7. The eccentric sleeve 6 is sleeved on the end of the driven roller. The bearing end cover 5 is fixedly installed on the main body 3 of the granulator 1 by a locking screw 13. A center hole 8 is provided in the center of the bearing end cover 5 for the end of the eccentric sleeve 6 to pass through. The bearing end cover 5 is sleeved on the outside of the eccentric sleeve 6. The locking block 7 is slidably connected to the bearing end cover 5 along the circumferential direction of the bearing end cover 5. A convex portion 9 axially protruding from the bearing end cover 5 is provided at the end of the eccentric sleeve 6. A groove 10 for the locking block 7 to engage is provided on the convex portion 9. A plurality of grooves 10 are distributed at intervals around the circumference. The locking block 7 has a clamping portion 11 adapted to the clamping slot 10. Through the clamping of the clamping portion 11 and the clamping slot 10, the eccentric sleeve 6 can be synchronously driven to rotate when the locking block 7 slides circumferentially to adjust the horizontal spacing between the two granulating rollers 2.

[0030] like Figure 1-Figure 3As shown, the locking block 7 is provided with an arc groove 12 that penetrates therethrough, and a locking piece is inserted into the arc groove 12. The locking piece is used to lock and fix the position of the locking block 7. In this embodiment, the locking piece is a locking screw 13, and the head of the locking screw 13 is larger than the width of the arc groove 12. At the same time, the bearing end cover 5 is provided with a threaded hole for threaded connection of the end of the locking screw 13. By tightening the locking screw 13, the locking block 7 can be pressed with the help of its head to achieve locking in the current position state. When the sliding locking block 7 needs to be adjusted, it only needs to loosen the locking screw 13, which is simple and convenient to operate.

[0031] like Figure 1 and Figure 2 As shown, an identification portion 14 is provided on the side wall of the bearing end cover 5, and the identification portion 14 is a notch opened on the side wall of the bearing end cover 5. At the same time, a marking portion 15 for aligning with the identification portion 14 is provided on the side wall of the locking block 7. There are multiple marking portions 15 spaced apart along the arc direction of the locking block 7. The marking portion 15 is an identification groove opened on the locking block 7, which is convenient for production and processing. The distances between adjacent marking portions 15 are different, and the distance between adjacent marking portions 15 gradually decreases from one end to the other end of the locking block 7. During the adjustment process, when the locking block 7 slides from the previous marking portion 15 corresponding to the identification portion 14 to the next marking portion 15 corresponding to the identification portion 14, the eccentric sleeve 6 is driven to rotate to achieve the same adjustment spacing for the granulating roller 2. In this embodiment, the distance of each sliding of the locking block 7 by one marking portion 15 is equal to the horizontal spacing adjustment of the granulating rollers 2 by 0.2 mm, which well achieves the equal spacing for each adjustment of the granulating rollers 2.

[0032] Through the pre-set marking part 15 and identification part 14, when the spacing of the granulating rollers needs to be adjusted, the locking piece is released and the adjustment is achieved by sliding the locking block 7 circumferentially and synchronously driving the eccentric sleeve 6 to rotate. Moreover, each sliding distance of the locking block 7 by an adjacent marking part 15 corresponds to the adjustment of the same spacing of the granulating rollers, which effectively realizes the adjustment of the equal spacing of the granulating rollers. In addition, with the help of the marking part 15 and the identification part 14, efficient and accurate adjustment can be achieved, and the adjustment operation is more convenient.

[0033] like Figure 1 and Figure 2 As shown, the end of the locking screw 13 passes through the bearing end cover 5 to form a connection end 16 for threaded connection and fixation with the main body 3. In this way, the locking screw 13 realizes the connection and fixation of the bearing end cover 5 and the main body 3 while simultaneously realizing the connection and fixation of the locking block 7. The same locking screw 13 is used to realize the connection and fixation at two places, thereby realizing the multi-purpose of the locking screw 13 and effectively simplifying the overall structure.

[0034] like Figure 2 and Figure 3As shown, the width of the slot 10 decreases gradually from the center of the circle toward the outside, and the engaging portion 11 on the locking block 7 is adapted to the slot 10, so that radial anti-slip limiting can be achieved, so that the engaging stability between the locking block 7 and the slot 10 is better, and it is convenient for the locking block 7 to stably drive the eccentric sleeve 6 to rotate for adjustment.

[0035] like Figure 1-Figure 3 As shown, both ends of the driven roller are provided with the present embodiment, so that the adjustment of the driven roller can be realized synchronously from both ends to ensure the final adjustment accuracy, and a radially penetrating oil inlet hole 17 is opened on the top of the eccentric sleeve 6, and a plurality of oil inlet holes 17 are distributed around the circumference at intervals, and the oil inlet holes 17 are distributed in the corresponding upper half of the eccentric sleeve 6, and at the same time, an inwardly concave oil groove 18 is provided on the outer surface of the eccentric sleeve 6, and the oil groove 18 is annular and connected to each oil inlet hole 17, so that in actual use, the oil can enter the interior through the oil inlet hole 17 and the oil groove 18 to realize lubrication of the bearing, improve the smoothness of the rotation of the granulating roller 2 and extend the service life of the bearing; in addition, there is a trimming portion 19 on one side of the bearing end cover 5, and the trimming portion 19 is a vertically oriented plane, and the trimming portions 19 on the two adjacent granulating rollers 2 are arranged oppositely, which is convenient for the orientation identification when the bearing end cover 5 is installed, and is convenient for the installation of the bearing end cover 5, and at the same time, the trimming portions 19 arranged opposite to each other can also play a role of circumferential limit, thereby improving the installation convenience of the bearing end cover 5.

[0036] Example 2

[0037] A granulation roller spacing regulator, such as Figure 4 As shown, the main difference between it and Example 1 is that the connection method between the locking block 7 and the eccentric sleeve 6 is different. In this embodiment, the locking block 7 is provided with two fastening screws 20 connected and fixed to the eccentric sleeve 6, so that the eccentric sleeve 6 can also be driven to rotate and adjust the angle by rotating the locking block 7. After the adjustment is completed, the locking screw 13 on the arc groove 12 is tightened to achieve locking. In addition, in this embodiment, the marking portion 15 is also arranged on the side wall of the locking block 7, and the identification portion 14 can be specifically arranged on the bearing end cover 5 to correspond to the marking portion 15; in addition, two auxiliary screws 21 are also connected to the eccentric sleeve 6, and adjacent auxiliary screws 21 form a spacing groove. When the eccentric sleeve 6 actually needs to be rotated and adjusted, a wrench can be inserted into the spacing groove for operation.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
