Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pressure roller device, and more particularly, to an adjustable pressure roller device. BACKGROUND

[0002] In the prior art, in the specific compounding process, the pressure roller and the abutting roller body are commonly abutted to realize the compounding of the sheet material. However, in the use process, the position of the pressure roller may deviate, and does not correspond to the abutting roller body, for example, there is a left-right front-back deviation condition; such error will directly affect the compounding effect. Especially when compounding ultra-thin materials, when the pressure roller has inconsistent left-right front-back conditions, it is easy to directly cause the wrinkles of the ultra-thin materials, the non-adhesion of the compounded materials, and the like; and it is easy to be obviously deviated with the production, and it is difficult to produce the compounded products meeting the specifications. It is impossible to continuously and effectively produce. At the same time, the common pressure roller structure in the prior art is embodied as a support that can be pressed down and a pressure roller fixed on the support, and the use of such pressure roller structure is not convenient for adjusting the position balance consistency and alignment of the pressure roller itself, and can only adjust the up-down movement of the pressure roller with the support; with the accumulation of production time, the deviation is difficult to be corrected.

[0003] Therefore, the prior art urgently needs an adjustable pressure roller that can accurately adjust the pressure roller itself and at the same time can guarantee the controllable pressure roller pressing and retraction. SUMMARY

[0004] The present application aims to overcome at least one of the above-mentioned deficiencies in the prior art, and provides an adjustable pressure roller device with simple structure, easy fine adjustment of the pressure roller balance, accurate corresponding to the abutting surface, and improved compounding quality.

[0005] The technical solution adopted by the present application is an adjustable pressure roller device, comprising: a pressure roller, two first compounding supports respectively located on both sides, the pressure roller is respectively installed on the first compounding supports on both sides; the first compounding support comprises a first mounting seat, a second mounting seat and a third mounting seat, the first mounting seat is used to adjust the position of the corresponding pressure roller end in the horizontal first direction; the second mounting seat is arranged on the first mounting seat, and the second mounting seat is used to adjust the position of the corresponding pressure roller end in the horizontal second direction, and the second direction is perpendicular to the first direction; the third mounting seat is arranged on the second mounting seat, and the pressure roller end is installed on the third mounting seat, and the third mounting seat is used to drive the pressure roller to press down or retract in the pressing direction. Wherein, the pressing direction intersects with the plane where the first direction is located and the plane where the second direction is located. Further, the first compounding supports on both sides are symmetrically arranged.

[0006] In the present application, the position of the corresponding pressure roller end in the first direction can be adjusted by adjusting the first mounting seat; the position of the corresponding pressure roller end in the second direction can be adjusted by adjusting the second mounting seat; when the first direction is the longitudinal direction, the second direction can be the transverse direction, thereby realizing the corresponding directional adjustment; for example, the right end of the pressure roller is offset backward compared with the left end, and there is a slight right offset of the corresponding abutting roller body relative to the lower end; at this time, the first mounting seat of the right first composite support can be adjusted first, thereby adjusting the front and back positions of the left and right ends of the pressure roller to be consistent, and then the second mounting seat of the first composite support on both sides can be adjusted to fine-tune the left offset of the pressure roller; until the lower surface of the pressure roller is parallel to and aligned with the corresponding abutting roller body. In the actual adjustment process, the first mounting seat and the second mounting seat can be fine-tuned to adjust the pressure roller to the appropriate position. At the same time, the third mounting seat can drive the pressure roller to press down and retract, thereby cooperating with the corresponding abutting roller body to press the composite. Through the cooperation of the first composite supports on both sides, the pressure roller can be fine-tuned in multiple directions, and at least in the horizontal direction, it can be adjusted to be aligned with the abutting roller body. For heavy equipment in the industry, the process of simply correcting the position can reduce the corresponding cost. Based on the adjustable pressure roller device of the present application, the pressure roller can be adjusted in multiple directions, and when the abutting roller surface is a fixed position equipment, the pressure roller can be flexibly adjusted to improve the composite precision. For example, when the abutting roller body is a large roller body embedded in the ground, the adjustable pressure roller can timely adjust the docking accuracy of the surface of the corresponding pressure roller and the surface of the abutting roller body, thereby ensuring the continuous production of the composite material and ensuring the corresponding composite and quality.

In addition to the offset of the pressure roller in the first direction and the second direction, the height can also be calibrated through the pad. When the heights of the two ends of the pressure roller are not consistent, in addition to being inconvenient to cooperate to composite, it will also directly cause the composite to deviate, or there is a loose composite on one side, which seriously affects the product quality. By arranging the pad between the first mounting seat and the second mounting seat, on the one hand, the pad does not need to occupy much space, and when cooperating with the second bolt, it effectively reduces the complexity of the process and the required workpieces for height adjustment, thereby reducing the cost, on the other hand, the height of the end can be adjusted, and the height of the two ends of the pressure roller can be effectively calibrated, so that the roller surface of the pressure roller is closely attached to the roller surface of the corresponding abutting roller body.

In the actual adjustment process, the first mounting seat 1110 and the second mounting seat 1120 can be fine-tuned to adjust the pressure roller 1200 to the appropriate position. At the same time, the third mounting seat 1130 can drive the pressure roller 1200 to press down and retract, so as to cooperate with the corresponding counter roller body to press the composite. Through the cooperation of the first composite supports 1100 on both sides, the pressure roller 1200 can be fine-tuned in multiple directions, and at least in the horizontal direction, it can be adjusted to be aligned with the counter roller body.

[0030] As shown in the figure, Figures 3-7 In the embodiment, the first mounting seat 1110 is formed by a first horizontal plate; and the second mounting seat 1120 is formed by a second horizontal plate.
