Description

Technical Field

[0001] This application relates to the technical field of press roller devices, and more specifically, to an adjustable press roller device. Background Art

[0002] In the prior art, during the specific lamination process, it is common for a press roller to abut against a holding roller body to achieve the lamination of sheets. However, during use, there may be a deviation in the position of the press roller, which does not correspond to the holding roller body. For example, there may be a situation of front-back deviation on the left and right sides; such errors will directly affect the lamination effect. Especially when laminating ultra-thin materials, when the press roller is inconsistent in the left-right and front-back directions, it is easy to directly cause wrinkles in the ultra-thin material and non-conformity of the laminated material; and it is easy to deviate significantly during production, making it difficult to produce a laminated product that meets the specifications. Continuous and effective production cannot be carried out. At the same time, the common press roller structures in the prior art mostly consist of a bracket that can be pressed down and a press roller fixed on the bracket. Using such a press roller structure is not convenient for adjusting to achieve the balance and alignment of the press roller itself and the balance state of the abutting surface, and only the up and down movement of the press roller along with the bracket can be adjusted; with the accumulation of production time, the deviation that occurs is difficult to correct.

[0003] Therefore, there is an urgent need in the prior art for an adjustable press roller that can accurately adjust the press roller itself and at the same time ensure controllable pressing down and retracting of the press roller. Summary of the Invention

[0004] This application aims to overcome at least one of the above-mentioned deficiencies in the prior art, and provides an adjustable press roller device with a simple structure, which is easy to finely adjust to balance the press roller and accurately correspond to the abutting surface, thereby improving the pressing quality.

[0005] The technical solution adopted by this application is an adjustable press roller device, including: a press roller, and two first lamination brackets respectively located on both sides. Both ends of the press roller are respectively installed on the first lamination brackets on both sides; the first lamination bracket includes 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 press 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 press 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 press roller end is installed on the third mounting seat. The third mounting seat is used to drive the press roller to press down or retract in the pressing-down direction. Among them, the pressing-down direction intersects the plane where the first direction is located and the plane where the second direction is located. Further, the first lamination brackets on both sides are symmetrically arranged.

[0006] In this application, through the adjustment of the first mounting seat, the position adjustment of the corresponding end of the pressure roller in the first direction can be achieved; through the adjustment of the second mounting seat, the position adjustment of the corresponding end of the pressure roller in the second direction can be achieved; when the first direction is longitudinal, the second direction can be transverse, so as to achieve the corresponding direction adjustment; for example, if the right end of the whole pressure roller is biased backward compared with the left end, and at the same time, it is slightly biased to the right compared with the corresponding abutting roller body below, then the first mounting seat of the first composite bracket on the right side can be adjusted first, so as to adjust the front and rear positions of the left and right ends of the pressure roller to be consistent, and then the second mounting seats of the first composite brackets on both sides can be adjusted to slightly offset the pressure roller to the left; until the lower surface of the pressure roller is parallel and aligned with the corresponding abutting roller body. In the actual adjustment process, the first mounting seat and the second mounting seat can be combined and finely adjusted to adjust the pressure roller to a suitable position. At the same time, through the third mounting seat, the pressure roller can be driven to press down and retract, so as to cooperate with the corresponding abutting roller body to press and laminate. Through the cooperation of the first composite brackets on both sides, the pressure roller can be finely adjusted in multiple directions, and at least it can be adjusted to be aligned with the abutting roller body in the horizontal direction. For heavy equipment in industry, the process of simply calibrating the position can be carried out, reducing the corresponding costs. Based on the adjustable pressure roller device of this application, the pressure roller can be adjusted in multiple directions. When the abutting roller surface is a fixed-position device, the pressure roller can be flexibly adjusted to improve the lamination accuracy. For example, when the abutting roller body is a large roller body buried in the ground, at this time, the corresponding pressure roller can be adjusted in time through the adjustable pressure roller to ensure the docking accuracy between the surface of the pressure roller and the surface of the abutting roller body, so as to ensure the continuous production of the composite material and ensure the corresponding lamination and quality.

[0007] Further, a height adjustment mechanism is further provided below the second mounting seat; the height adjustment mechanism is used to adjust the height of the corresponding side of the second mounting seat. Further, it is at least used to finely adjust the height of the corresponding end of the pressure roller on the corresponding side, as well as the front and rear tilt angles, etc. Further, the height adjustment mechanism includes a height adjustment bolt and a cushion block fixed on the first mounting seat below the second mounting seat; a height adjustment bolt hole is provided on the second mounting seat, and the lower end of the height adjustment bolt abuts against the cushion block / the bottom of the cushion block. The height adjustment bolt rotates and cooperates with the cushion block to abut against to adjust the height of the corresponding side of the second mounting seat. In addition to the offset of the pressure roller in the first direction and the second direction, height calibration can also be achieved through the cushion block. When the heights of the two ends of the pressure roller are inconsistent, in addition to being inconvenient to cooperate for lamination, it will also directly cause the lamination to deviate, or there will be a loose lamination on one side, seriously affecting the product quality. By providing a cushion block between the first mounting seat and the second mounting seat, on the one hand, the cushion block does not need to occupy too much extra space, and when cooperating with the second bolt, it effectively reduces the complexity of the process and the required workpieces for achieving height adjustment, reducing costs. On the other hand, it can achieve the adjustment of the end height, effectively calibrate the heights of the two ends of the pressure roller, and make the roller surface of the pressure roller closely fit with the roller surface of the corresponding abutting roller body.

[0008] Further, a limiting block is provided on the first mounting base in the second direction, and the limiting block is used to limit the moving range of the second mounting base in the second direction. Further, the first mounting base is formed by a first horizontal plate, and the limiting block is a baffle above the end of the first horizontal plate; the second mounting base is formed by a second horizontal plate. Through the limiting block, the fine-tuning range of the corresponding second mounting base can be limited, so as to facilitate the controllable and accurate adjustment of the position in the second direction and avoid excessive adjustment.

[0009] Further, a first bolt and a second bolt are further included. A first long circular hole with the length direction being the first direction is provided on the first mounting base, and the first long circular hole cooperates with the first bolt to adjust the position of the first mounting base in the first direction on the mounting surface; a second bolt hole is further provided on the first mounting base, and a second long circular hole with the length direction being the second direction is provided on the second mounting base, and the second long circular hole cooperates with the second bolt to adjust the position of the second mounting base in the second direction on the first mounting base. That is, a fine-tuning space is provided through the first long circular hole, and then it is locked to the mounting surface through the first bolt, so that it can be fixed at the fine-tuned position. A first bolt hole cooperating with the first bolt is provided on the mounting surface below the first mounting base, so as to cooperate to realize the function of the first mounting base. Similarly, when the second mounting base is installed above the first mounting base, a second bolt hole can be arranged on the first mounting base to provide a fixing position for the second bolt, and the second bolt can cooperate with the second long circular hole on the second mounting base to fine-tune and fix the position.

[0010] Further, the third mounting base includes a wall panel and a downward pressing direction driving device fixed on the wall panel, and the end of the pressing roller is installed on the downward pressing direction driving device; further, the downward pressing direction is parallel to the wall panel, and the downward pressing direction forms an included angle α with the vertical direction, and the range of α is 15-60°. Further, the third direction driving device includes a driving assembly, a guide rail, and a slider adapted to the guide rail, and the end of the pressing roller is installed on the slider.

[0011] Further, at least one guide roller is arranged on the front side of the pressing roller; and / or, a tension adjusting roller is arranged on the rear side of the pressing roller, and a tension sensor is connected to the end of the tension adjusting roller. Further, the pressing roller is lower than the tension adjusting roller. Through the tension adjusting roller, the tension can be adjusted in real time in cooperation with the upstream and downstream running rollers, so as to maintain a certain degree of stretching, enable the sheets to be flatly compounded, and reduce defects such as wrinkles and air gaps in the compounding process. The guide roller cooperates with the pressing roller to facilitate the introduction or export of the compounding area.

[0012] Further, the end of the over-roller and / or the end of the tension adjusting roller are mounted on the first composite bracket through an adjusting seat; the adjusting seat includes a limiting protrusion, a fixing block, and a third bolt. The limiting protrusion is located outside the fixing block, and there is an adjusting gap between the limiting protrusion and the fixing block; the end of the roller body is mounted on the fixing block, and a third long circular hole is provided on the fixing block. The third long circular hole cooperates with the third bolt to adjust the position of the fixing block inside the limiting protrusion. Through the adjusting seat, the positions of the left and right ends of the over-roller and the tension adjusting roller can also be realized, and further, the fine adjustment of the end positions of the over-roller and the tension adjusting roller can be realized to calibrate the relatively parallel positions, so that the material feeding can proceed smoothly and continuously; and the structure is simple, easy to install and maintain, and does not affect the normal operation of the corresponding installed roller body.

[0013] Further, a lifting bolt is provided at the upper end of the third mounting seat. When the pressure roller and the first composite bracket are relatively fixed as a whole, the lifting bolt can provide a lifting position, which is convenient for transferring and installing the integrally adjustable pressure roller to a specific position.

[0014] Further, a positioning reinforcing rod is also included, and both ends of the positioning reinforcing rod are respectively fixed on the first composite bracket. Further, the positioning reinforcing rod is higher than the bottom surface of the pressure roller. Through the positioning reinforcing rod, the stability of the positions of the first composite brackets on both sides can be enhanced, and the position stability of the corresponding pressure roller can be ensured.

Detailed implementation manners

[0028] The attached drawings of this application are only for illustrative purposes and should not be construed as a limitation to this application. For better explaining the following embodiments, some components in the drawings will be omitted, enlarged or reduced, which do not represent the dimensions of the actual products; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted. Embodiment 1

[0029] As Figures 1 - 10As shown in the figure, this embodiment discloses an adjustable pressure roller 1200 device 1000, including: a pressure roller 1200, and first composite brackets 1100 located on both sides. Both ends of the pressure roller 1200 are respectively installed on the first composite brackets 1100 on both sides, and the first composite brackets 1100 on both sides are symmetrically arranged; the first composite bracket 1100 includes a first mounting seat 1110, a second mounting seat 1120, and a third mounting seat 1130. The first mounting seat 1110 is used to adjust the position of the corresponding end of the pressure roller 1200 in the horizontal first direction; the second mounting seat 1120 is arranged on the first mounting seat 1110, and the second mounting seat 1120 is used to adjust the position of the corresponding end of the pressure roller 1200 in the horizontal second direction, and the second direction is perpendicular to the first direction; the third mounting seat 1130 is arranged on the second mounting seat 1120, and both ends of the pressure roller 1200 are installed on the third mounting seat 1130. The third mounting seat 1130 is used to drive the pressure roller 1200 to press down or retract in the downward pressing direction; the downward pressing direction intersects the plane where the first direction is located and the plane where the second direction is located. During the actual adjustment process, the first mounting seat 1110 and the second mounting seat 1120 can be combined for fine adjustment to adjust the pressure roller 1200 to a suitable position. At the same time, for the third mounting seat 1130, the pressure roller 1200 can be driven to press down and retract, so as to cooperate with the corresponding abutting roller body for pressing and laminating. Through the cooperation of the first composite brackets 1100 on both sides, the pressure roller 1200 can be finely adjusted in multiple directions, and at least can be adjusted to align with the abutting roller body in the horizontal direction.

[0030] As Figures 3 - 7 shown in the figure, in this embodiment, the first mounting seat 1110 is formed by a first horizontal plate; the second mounting seat 1120 is formed by a second horizontal plate. A height adjustment mechanism is further provided below the second mounting seat 1120; the height adjustment mechanism adjusts the height of the corresponding side of the second mounting seat 1120; at least used to finely adjust the height of the corresponding end of the pressure roller 1200, as well as the front-back tilt angle, etc.; in this embodiment, the height adjustment mechanism includes a height adjustment bolt and a cushion block 1141 fixed on the first mounting seat 1110 below the second mounting seat 1120; a height adjustment bolt hole 1122 is opened on the second mounting seat 1120, the lower end of the height adjustment bolt abuts on the cushion block 1141, and the height adjustment bolt rotates and cooperates with the cushion block 1141 to abut to adjust the height of the corresponding side of the second mounting seat 1120. That is, in addition to the offset of the pressure roller 1200 in the first direction and the second direction, height calibration can also be achieved through the height adjustment mechanism to keep the pressure roller 1200 parallel to the abutting roller body.

[0031] Example of the specific implementation principle. In the present application, through the adjustment of the first mounting seat 1110, the position of the corresponding end of the pressure roller 1200 in the first direction can be achieved; through the adjustment of the second mounting seat 1120, the position of the corresponding end of the pressure roller 1200 in the second direction can be achieved; when the first direction is longitudinal, the second direction can be transverse, so as to achieve the corresponding direction adjustment. For example, if the right end of the whole pressure roller 1200 is biased backward compared with the left end and is slightly biased to the right compared with the corresponding abutting roller body below, then the first mounting seat 1110 of the right-side first composite bracket 1100 can be adjusted first to make the front and rear positions of the left and right ends of the pressure roller 1200 consistent, and then the second mounting seats 1120 of the two-side first composite brackets 1100 can be adjusted to finely adjust the leftward offset of the pressure roller 1200 until the lower surface of the pressure roller 1200 is aligned with the corresponding abutting roller body. When there is also an imbalance in height, the height of the corresponding end can be further adjusted by the height adjustment mechanism. For example, if the left side is high and the right side is low, the height adjustment mechanism in the left-side first composite bracket 1100 can be adjusted to make the height of the left side of the bottom surface of the pressure roller 1200 the same as that of the right side. In the actual process, by rotating the height adjustment bolt, the side of the second mounting seat 1120 where the height adjustment mechanism is arranged can be made to drop relative to the position of the bolt, so as to adjust the height of the corresponding second mounting seat 1120 area on this side, and further adjust the height of the corresponding side of the pressure roller 1200. Specifically, when height adjustment mechanisms are arranged on both the front and rear sides of the corresponding end of the single second mounting seat 1120 symmetrically with respect to the pressure roller 1200, more accurate and diverse adjustment methods can be achieved to adapt to the required adjustment conditions under different deviations. Specifically, height adjustment mechanisms are arranged on both the first composite brackets 1100 on both sides in this embodiment.

[0032] As Figures 3 - 4 shown, in this embodiment, a limit block 1113 is further provided on the first mounting seat 1110 in the second direction, and the limit block 1113 is used to limit the moving range of the second mounting seat 1120 in the second direction. The limit block 1113 is formed by a baffle above the end of the first horizontal plate. Through the limit block 1113, the fine adjustment range of the corresponding second mounting seat 1120 is limited.

[0033] In the specific implementation of the position adjustment method of the first mounting seat 1110 and the second mounting seat 1120, it is achieved by the cooperation of bolts and oblong holes. For example, in this embodiment, the adjustable pressure roller 1200 device 1000 further includes a first bolt and a second bolt. The first mounting seat 1110 is provided with a first oblong hole 1111 in the first direction of the length direction. The first oblong hole 1111 cooperates with the first bolt to adjust the position of the first mounting seat 1110 in the first direction on the mounting surface. The first mounting seat 1110 is further provided with a second bolt hole 1112. The second mounting seat 1120 is provided with a second oblong hole 1121 in the second direction of the length direction. The second oblong hole 1121 cooperates with the second bolt to adjust the position of the second mounting seat 1120 in the second direction on the first mounting seat 1110. That is, a fine adjustment space is provided by the first oblong hole 1111, and then it is locked to the mounting surface by the first bolt, so that it can be fixed at the fine-adjusted position. A first bolt hole cooperating with the first bolt is provided on the mounting surface below the first mounting seat 1110, so as to cooperate to realize the function of the first mounting seat 1110. Similarly, when the second mounting seat 1120 is installed above the first mounting seat 1110, the second bolt hole 1112 can be arranged on the first mounting seat 1110, so as to provide a fixed position for the second bolt. The second bolt can cooperate with the second oblong hole 1121 on the second mounting seat 1120 to finely adjust and fix the position.

[0034] As Figures 8 - 9 shown, in this embodiment, the third mounting seat 1130 includes a wall panel 1131 and a downward pressure driving device fixed on the wall panel 1131. The end of the pressure roller 1200 is installed on the downward pressure driving device. The downward pressure direction is parallel to the wall panel 1131, and the downward pressure direction forms an angle α with the vertical direction, and the range of α is 15 to 60°. For the convenience of installation, a lifting bolt 1132 is provided at the upper end of the wall panel 1131. The third direction driving device includes a cylinder driving assembly 1133, a guide rail 1134, and a slider 1135 adapted to the guide rail 1134. The end of the pressure roller 1200 is installed on the slider 1135. The cylinder driving assembly 1133 includes a cylinder and a cylinder fixing plate. The cylinder is installed on the wall panel 1131 through the cylinder fixing plate. The cylinder drives the piston rod to drive the slider 1135 to move on the slide rail, and the length direction of the slide rail is the downward pressure direction.

[0035] As Figures 1 - 2 shown, in order to realize the flat stretching and import and export of the material before and after pressing, in this embodiment, at least one guide roller 1300 is arranged on the front side of the pressure roller 1200; and, a tension adjusting roller 1400 is arranged on the rear side of the pressure roller 1200, and a tension sensor is connected to the end of the tension adjusting roller 1400. The pressure roller 1200 is lower than the tension adjusting roller 1400.

[0036] The end of the over-roller 1300 and the end of the tension adjusting roller 1400 are installed on the first composite bracket 1100 through the adjusting seat 1150; as Figure 10 shown, the adjusting seat 1150 includes a limit projection 1152, a fixing block 1151, and a third bolt. The limit projection 1152 is located outside the fixing block 1151, and an adjusting gap is left between the limit projection 1152 and the fixing block 1151. The end of the roller body is installed on the fixing block 1151. The fixing block 1151 is provided with a third long circular hole 1153, and the third long circular hole 1153 cooperates with the third bolt to adjust the position of the fixing block 1151 inside the limit projection 1152.

[0037] As Figures 1 - 2 shown, to strengthen the structural stability of the overall adjustable pressure roller 1200 device 1000, a positioning and strengthening rod 1500 is further provided in this embodiment. Both ends of the positioning and strengthening rod 1500 are respectively fixed on the first composite bracket 1100. The positioning and strengthening rod 1500 is higher than the bottom surface of the pressure roller 1200, which is convenient for the pressure roller 1200 to press and roll the running roller.
