Description

Technical Field

[0001] This utility model relates to the field of medium and high rollers, specifically an adjustable medium and high roller. Background Technology

[0002] The medium-high roller shaft, with its olive-shaped structure where the diameter of the middle section is slightly larger than that of both ends, effectively compensates for the bending deformation of the roller when it rotates under pressure. This ensures uniform pressure distribution when in contact with steel rollers or substrates, thereby improving equipment operating efficiency and product quality in various fields such as printing and packaging, papermaking, and transportation, and reducing problems such as local wear and paper warping. It is a key component for ensuring stable contact pressure under dynamic loads.

[0003] In existing technologies, the length of medium-high rollers is usually fixed. However, in actual use, since the length of medium-high rollers is fixed, multiple rollers are often equipped to adapt to production needs. During the production process, medium-high rollers of different lengths are replaced to adapt to the product, resulting in high roller usage costs. Therefore, an adjustable medium-high roller is proposed to address the above problems. Utility Model Content

[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 scope of protection of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] This application discloses an adjustable medium-high roller shaft. (See also...) Figure 1 , Figure 2 , Figure 3 and Figure 5 An adjustable medium-high roller shaft includes two main roller shafts 1, several auxiliary roller shafts 2, two main rotating shafts 3, two auxiliary rotating shafts 4, and several sub-rotating shafts 5. The several auxiliary roller shafts 2 cooperate with the two main roller shafts 1, the two auxiliary rotating shafts 4 cooperate with the two main roller shafts 1, the two main rotating shafts 3 cooperate with the two auxiliary rotating shafts 4 respectively, and the several sub-rotating shafts 5 cooperate with the two auxiliary rotating shafts 4. A connecting component 6 is provided on the opposite side of the two auxiliary rotating shafts 4 and the several sub-rotating shafts 5. A first locking block 31 is fixedly connected to the opposite side of the two main rotating shafts 3. A first locking groove 32 is opened on the opposite side of the two auxiliary rotating shafts 4. The first locking block 31 cooperates with the first locking groove 32.

[0027] The connecting assembly 6 includes several connecting rods 61 and several connecting grooves 62. The connecting grooves 62 are respectively opened on one side of the two auxiliary rotating shafts 4 and on both sides of the sub-rotating shaft 5. The two ends of the connecting rods 61 are respectively inserted into the interior of the connecting grooves 62. A support rod 63 is fixedly connected inside the connecting groove 62. A support sleeve 64 is slidably fitted on the surface of the support rod 63. A support plate 65 is fixedly installed on one end of the support sleeve 64. A spring 66 is slidably fitted on the surfaces of the support rod 63 and the support sleeve 64. One end of the spring 66 is fixedly connected to the inner wall of the connecting groove 62, and the other end of the spring 66 is fixedly connected to one side of the support plate 65. The other side of the support plate 65 abuts against one end of the connecting rod 61.

[0028] The surfaces of the two main rotating shafts 3 are respectively fitted with a fixed frame 9 and a connecting frame 91. A screw 92 is rotatably connected to the side of the connecting frame 91 opposite to the fixed frame 9. One end of the screw 92 is threaded into the inside of the fixed frame 9.

[0029] When adjusting the length of the medium and high roller shafts, rotate screw 92 to adjust the distance between connecting frame 91 and fixed frame 9, thereby adjusting the distance between the two main rotating shafts 3, so that the first locking block 31 separates from the first locking groove 32, thus separating the main rotating shaft 3 from the auxiliary rotating shaft 4. Then, pull the auxiliary rotating shaft 4 to separate the auxiliary rotating shaft 4 from the sub-rotating shaft 5, thereby separating the main roller shaft 1 from the auxiliary roller shaft 2. Thus, the auxiliary roller shaft 2 and sub-rotating shaft 5 can be removed or added as needed. After the number of auxiliary roller shafts 2 is adjusted, the corresponding number of sub-rotating shafts 5 can be added. The rotating shaft 5 is connected, and the two auxiliary rotating shafts 4 are connected to the sub-rotating shaft 5. The main rotating shaft 3 and the auxiliary rotating shaft 4 are connected to the inside of the main roller shaft 1 and the auxiliary roller shaft 2. The two main rotating shafts 3 are aligned with the two auxiliary rotating shafts 4 respectively. Then, the screw 92 is rotated to adjust the distance between the connecting frame 91 and the fixing frame 9, so that the first locking block 31 is inserted into the inside of the first locking slot 32, so that the two main rotating shafts 3 support the two auxiliary rotating shafts 4 and several sub-rotating shafts 5, thereby achieving the function of positioning the main roller shaft 1 and the auxiliary roller shaft 2, so as to complete the length adjustment of the medium and high roller shafts.

[0030] Reference Figure 2 Limiting rods 21 are fixedly connected to one side of several auxiliary rollers 2 and one side of two main rollers 1. One end of the limiting rod 21 passes through the main roller 1 and the auxiliary rollers 2, and the surface of the limiting rod 21 is slidably connected to the inner cavity of the main roller 1 and the auxiliary rollers 2. By setting the limiting rods 21 on one side of the two main rollers 1 and on both sides of the auxiliary rollers 2, the position between the two main rollers 1 and several auxiliary rollers 2 can be stabilized by the limiting rods 21.

[0031] Reference Figure 2 and Figure 3 The surfaces of the auxiliary shaft 4 and the sub-shaft 5 are each provided with a second slot 8. The inner walls of the main roller shaft 1 and the auxiliary roller shaft 2 are each fixedly installed with a second block 7. The second block 7 is used in conjunction with the second slot 8. By using the second block 7 in conjunction with the second slot 8, the main shaft 3, the auxiliary shaft 4 and the sub-shaft 5 can drive the main roller shaft 1 and the auxiliary roller shaft 2 to rotate.

[0032] Reference Figure 4 A limiting block 67 is fixedly installed on the inner wall of the support sleeve 64, and a limiting groove 68 is formed on the surface of the support rod 63. The surface of the limiting block 67 is slidably connected to the inner cavity of the limiting groove 68. By sliding the surface of the limiting block 67 to the inner cavity of the limiting groove 68, the docking position of the support sleeve 64 and the support rod 63 is effectively stabilized. Thus, the position of the spring 66 is stabilized by the support rod 63 and the support sleeve 64, so that the spring 66 plays a supporting role between the connecting rod 61 and the connecting groove 62, thereby ensuring the stability of the docking position of the connecting rod 61 and the connecting groove 62.

[0033] Reference Figure 5The other end of the screw 92 is fixedly installed with a first positioning block 9201, which is rotatably connected to the inside of the connecting frame 91. The first positioning block 9201 is rotatably connected to the inside of the connecting frame 91 to effectively stabilize the position of the screw 92 and prevent the screw 92 from separating from the connecting frame 91 and affecting the position of the fixing frame 9 and the connecting frame 91.

[0034] Reference Figure 5 A positioning rod 93 is fixedly connected to the side of the connecting frame 91 opposite to the fixed frame 9. A positioning groove 9301 is provided on the side of the fixed frame 9 opposite to the connecting frame 91. One end of the positioning rod 93 is slidably connected inside the positioning groove 9301. By sliding one end of the positioning rod 93 inside the positioning groove 9301, the relative positions of the fixed frame 9 and the connecting frame 91 are stabilized through the positioning rod 93 and the positioning groove 9301, so as to avoid the relative positions of the fixed frame 9 and the connecting frame 91 from shifting and affecting the positions of the two main rotating shafts 3.

[0035] Reference Figure 5 Each of the two main rotating shafts 3 has a second positioning block 94 fixedly installed on its surface. The two second positioning blocks 94 are respectively rotatably sleeved inside the fixed frame 9 and the connecting frame 91. By rotatably connecting the two second positioning blocks 94 inside the fixed frame 9 and the connecting frame 91, the fixed frame 9 and the connecting frame 91 can drive the two main rotating shafts 3 to move while avoiding affecting the rotation of the two main rotating shafts 3, so as to adjust the distance between the two main rotating shafts 3.

[0036] Working principle: When adjusting the length of the medium and high roller shafts, rotate the screw 92 and stabilize its position through the first positioning block 9201. One end of the positioning rod 93 is slidably connected inside the positioning groove 9301, stabilizing the relative position of the connecting frame 91 and the fixed frame 9, thereby adjusting the distance between them. This allows the connecting frame 91 and the fixed frame 9 to move the two main rotating shafts 3 via the second positioning block 94, thus adjusting the distance between them. This causes the first locking block 31 to separate from the first locking groove 32, separating the main rotating shaft 3 from the auxiliary rotating shaft 4. The auxiliary rotating shaft 4 and the sub-rotating shaft 5 can then be removed. Next, separate the main roller shaft 1 from the auxiliary roller shaft 2. As needed, the auxiliary roller shaft 2 can be removed or added. After adjusting the number of auxiliary roller shafts 2, when connecting several sub-rotating shafts 5 or connecting sub-rotating shafts 5 with auxiliary roller shafts 4, insert both ends of the connecting rod 61. Inside the connecting groove 62, the positions of the support rod 63 and the support sleeve 64 are stabilized by the limiting block 67 and the limiting groove 68, so that the support rod 63 and the support sleeve 64 stabilize the position of the spring 66, so that the spring 66 plays a supporting role between the connecting rod 61 and the connecting groove 62, so as to connect the sub-rotating shafts 5 corresponding to the number of auxiliary roller shafts 2, and then connect the two auxiliary rotating shafts 4 with several sub-rotating shafts 5, and connect the main rotating shaft 3 and the auxiliary rotating shaft 4 into the interior of the main roller shaft 1 and the auxiliary roller shaft 2, and insert the second locking block 7 into the interior of the second locking groove 8, then align the two main rotating shafts 3 with the two auxiliary rotating shafts 4, and rotate the screw 92 to adjust the distance between the fixing frame 9 and the connecting frame 91, so that one end of the first locking block 31 is inserted into the interior of the first locking groove 32, so that the two main rotating shafts 3 support the two auxiliary rotating shafts 4 and several sub-rotating shafts 5, thereby achieving the function of positioning the main roller shaft 1 and the auxiliary roller shaft 2, so as to complete the length adjustment of the medium and high roller shafts.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
