[0029] like Figure 1 As shown, the utility model provides a roller adjustment device for convenient roller adjustment, including a housing 1, a screw adjustment assembly 2, a first auxiliary roller 41 and a second auxiliary roller 42. Among them, the screw adjustment assembly 2 includes a transverse screw 21 horizontally mounted in the housing 1, a longitudinal screw 22 longitudinally mounted at both ends of the housing 1, and a connecting member 3 for connecting the longitudinal screw 22 and the transverse screw 21. At the same time, the transverse screw 21 is rotatably connected to the connecting member 3, the longitudinal screw 22 is threadedly connected to the connecting member 3, and the transverse screw 21 moves up and down along the height direction of the housing 1 with the rotation of the longitudinal screw 22. In addition, the first auxiliary roller 41 and the second auxiliary roller 42 are threadedly connected to the transverse screw 21 and move synchronously toward or away from each other along the horizontal direction of the housing 1 with the rotation of the transverse screw 21. At the same time, an opening is provided in the middle of the lower bottom surface of the housing 1, and a main roller 5 is elastically floatingly provided above the opening, and the first auxiliary roller 41 and the second auxiliary roller 42 are provided on both sides of the main roller 5 and are tangent to the main roller 5. The opposite side walls of the shell 1 are provided with an elastic floating structure for supporting the main roller 5 to float up and down. The elastic floating structure can be set as a spring, which bears the weight of the main roller 5 and further supports the main roller 5 to float up and down. The specific structural setting of this elastic floating structure has been disclosed in the relevant technology and will not be described in detail here.

[0030] In this embodiment, by providing a transverse screw rod 21, a longitudinal screw rod 22 and a connecting piece 3, the transverse screw rod 21 moves up and down along the height direction of the shell 1 as the longitudinal screw rod 22 rotates, and the first auxiliary roller 41 and the second auxiliary roller 42 move synchronously toward or away from each other along the horizontal direction of the shell 1 as the transverse screw rod 21 rotates, thereby conveniently and flexibly adjusting the movement of the first auxiliary roller 41 and the second auxiliary roller 42 in the longitudinal and transverse directions, thereby achieving the purpose of changing the pressure and position of the main roller 5. The adjustment structure is simple, efficient, convenient and fast.

[0031] Furthermore, the transverse screw rod 21 is threadedly connected to the second bearing seat 12, and both ends of the first auxiliary roller 41 and the second auxiliary roller 42 are rotatably connected to the corresponding second bearing seat 12. Figure 2As shown, the second bearing seat 12 disposed at the end of the pressure roller is provided with a threaded hole 32 connected to the screw thread along the radial direction of the pressure roller, and the threaded holes 32 on the bearing seats on the left and right sides are respectively matched with the threads of the threaded section B of the transverse screw 21. The transverse screw 21 includes an upper screw 211 and a lower screw 212 which are arranged in parallel and spaced on the housing 1, and the two ends of the upper screw 211 and the lower screw 212 are respectively connected to the corresponding longitudinal screw 22 through a connecting member 3. The first auxiliary roller 41 and the second auxiliary roller 42 are threadedly connected to the lower screw 212 through the second bearing seat 12, and the upper screw 211 is threadedly connected to the third auxiliary roller 43 and the fourth auxiliary roller 44 through the second bearing seat 12. The third auxiliary roller 43 is tangent to the first auxiliary roller 41, and the fourth auxiliary roller 44 is tangent to the second auxiliary roller 42. By providing the upper screw 211 and the lower screw 212, the pressure of the third auxiliary roller 43 and the fourth auxiliary roller 44 on the main roller 5 is increased to better adjust the position of the main roller 5.

[0032] like Figure 3 As described above, a polished rod section A is provided in the middle of the transverse screw rod 21, and threaded sections B with opposite thread rotation directions are provided at both ends of the polished rod section A; the length of the polished rod section A is equal to or less than the sum of the radii of the first auxiliary roller 41 and the second auxiliary roller 42. This arrangement can effectively reduce the cost of screw rod processing, improve the efficiency of screw rod processing, and make the first auxiliary roller 41 and the second auxiliary roller 42 move synchronously toward or away from each other when the transverse screw rod 21 rotates. That is, when the transverse screw rod 21 rotates forward, the first auxiliary roller 41 and the second auxiliary roller 42 move synchronously toward each other; when the transverse screw rod 21 rotates reversely, the first auxiliary roller 41 and the second auxiliary roller 42 move synchronously away from each other.

[0033] On the other hand, the longitudinal screw rods 22 arranged at both ends of the transverse screw rod 21 have the same thread rotation direction, and the two ends of the longitudinal screw rod 22 are respectively rotatably connected to the first bearing seat 11 arranged outside the opposite side walls of the housing 1. The structural setting of the longitudinal screw rod 22 is used to adjust the position of the transverse screw rod 21 in the height direction of the housing 1. Through the rotation of the above-mentioned transverse screw rod 21 and the longitudinal screw rod 22, the movement of the first auxiliary roller 41 and the second auxiliary roller 42 in the longitudinal and transverse directions can be conveniently and flexibly adjusted, thereby achieving the purpose of changing the pressure and position of the main roller 5.

The transverse screw rod 21 and the longitudinal screw rod 22 are connected by the connecting member 3, and the transverse screw rod 21 can move up and down along the height direction of the housing 1 when the longitudinal screw rod 22 rotates.

[0035] like Figure 6 As shown, a driving device 6 for driving the synchronous rotation of the transverse screw rods 21 or the longitudinal screw rods 22 is provided between adjacent transverse screw rods 21 and adjacent longitudinal screw rods 22. In order to further improve the automation level of the adjustment device, this scheme takes the adjacent transverse screw rods 21 as an example, and sets a pulley 61 at the same end between the upper screw rod 211 and the lower screw rod 212, and drives the screw rod to rotate by means of a synchronous belt 62 and a motor 63, and sets a sensor for detecting the displacement on the end shaft of the pressure roller, so as to realize the precise control of the displacement of the pressure roller; similarly, the driving device 6 set between adjacent longitudinal screw rods 22 is the same as the driving device set between adjacent transverse screw rods 21, and will not be described in detail here.

[0036] In addition, the present embodiment can also manually drive the rotation of the transverse screw rod 21 and the longitudinal screw rod 22. In order to facilitate the manual rotation of the transverse screw rod 21 and the longitudinal screw rod 22, adjustment handles can be respectively provided at the exposed ends of the screw rods, so that the longitudinal and transverse positions of the first auxiliary roller 41, the second auxiliary roller 42, the third auxiliary roller 43 and the fourth auxiliary roller 44 can be conveniently and flexibly adjusted through the rotation of the upper screw rod 211, the lower screw rod 212 and the longitudinal screw rods 22 on the left and right sides, thereby achieving the purpose of adjusting the pressure and position of the main roller 5.

It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
