[0031] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0032] The inventors have discovered through research that, in the existing pressure adjustment operation of the pressure roller, the pressure roller is usually driven by a linear drive mechanism to move closer to or away from the active roller. Because the driving direction of the linear drive mechanism is collinear with the moving direction of the pressure roller, it is difficult to achieve precise adjustment of the pressure roller during the driving process, resulting in the pressure force applied by the pressure roller on the active roller being not precise enough.

[0033] Please refer to Figure 1 and Figure 2 The pressure regulating mechanism 100 and the laminating machine provided in the embodiment of the present invention can solve the above-mentioned problems, which will be described in detail below.

[0034] refer to Figure 1 and Figure 2 The pressure regulating mechanism 100 is used for a laminating machine, and the pressure regulating mechanism 100 includes a driving member 110, an eccentric disc 120, a connecting member 130 and a pressure roller 140;

[0035] Among them, the eccentric disk 120 is connected to the driving member 110 in a transmission manner, one end of the connecting member 130 is movably matched with the eccentric disk 120, and the other end of the connecting member 130 is connected to the pressure roller 140. The pressure roller 140 is used to be arranged parallel to the active roller 200, and the driving member 110 is used to drive the eccentric disk 120 to rotate, so that the connecting member 130 drives the pressure roller 140 to approach or move away from the active roller 200.

[0036] During operation, the driving member 110 is used to provide driving force for rotational motion, and drives the pressure roller 140 to move linearly through the active cooperation of the eccentric disk 120 and the connecting member 130, so that the pressure roller 140 approaches or moves away from the active roller 200. Compared with linear drive, precise adjustment of the position of the pressure roller 140 can be achieved, ensuring that the pressing force applied by the pressure roller 140 to the active roller 200 is more precise.

[0037] refer to Figure 2 The driving member 110 includes a power source 111 and a reducer 112 that are transmission-connected. The eccentric disk 120 is arranged at the output end of the reducer 112. The reducer 112 is used to drive the eccentric disk 120 to rotate.

[0038] The power source 111 is used to provide drive and perform rotational motion, and the reducer 112 is used to perform reduced speed transmission. The power source 111 can be a rotary electric cylinder, a rotary air cylinder, or a rotary hydraulic cylinder, and its specific power form is not limited.

[0039] It should be noted that in order to make the transmission process more responsive and more precise, the power source 111 is preferably a servo motor. Furthermore, the output torque of the servo motor and the reduction ratio of the reducer 112 can be selected according to the actual required pressing force.

[0040] Furthermore, the reversing speed of the pressure roller 140 depends on the accuracy, load and motor inertia ratio of the servo motor. Through reasonable selection, one reversing action can be achieved within the range of 0.01s to 0.02s.

[0041] refer to Figure 2 The eccentric disk 120 includes a disk body 121 and a disk shaft 122 connected to each other. The disk body 121 is connected to the output end of the reducer 112. The disk shaft 122 is eccentrically arranged on the disk body 121. The disk shaft 122 is movably matched with one end of the connecting member 130.

[0042] During the transmission operation, the reducer 112 can drive the disc shaft 122 to rotate eccentrically on the disc body 121. It should be noted that the disc body 121 can be regarded as a cam mechanism, and the eccentricity of the cam can be set according to the actual clamping force adjustment range. In combination with the selection of the servo motor and the reducer 112, the transmission of the entire mechanism can be achieved steplessly.

[0043] It is worth noting that in order to facilitate the movable cooperation between the disk shaft 122 and one end of the connecting member 130 to reduce the friction, the cross section of the disk shaft 122 can be made circular.

[0044] refer to Figure 1An adjusting portion 1301 is provided at the end of the connecting member 130 . The adjusting portion 1301 is in the shape of an elongated strip and an extending direction of the elongated strip forms an angle with a direction from the pressure roller 140 to the active roller 200 .

[0045] Specifically, the adjustment portion 1301 is an elongated hole or an elongated groove, and at least a portion of the disk shaft 122 is accommodated in the elongated groove, or the disk shaft 122 passes through the elongated hole.

[0046] In this embodiment, the elongated extending direction of the adjusting portion 1301 (ie, the elongated hole or the elongated groove) and the direction from the pressing roller 140 to the active roller 200 can be perpendicular to each other.

[0047] Of course, an angle α can be formed between the elongated extension direction of the adjustment portion 1301 (i.e., the elongated hole or elongated groove) and the direction from the pressure roller 140 to the active roller 200, wherein 45°≤α≤135°, preferably α=90°. In other embodiments, the specific size of α can be 45°, 60°, 75°, 105°, 120, 135°, etc., and there is no limitation on its specific size.

[0048] In this embodiment, the adjustment portion 1301 is an elongated hole, and the end of the disk shaft 122 away from the disk body 121 protrudes from the elongated hole. To prevent the end of the disk shaft 122 away from the disk body 121 from easily separating from the elongated hole, a limit buckle 123 can be connected to this end. The size of the limit buckle 123 is larger than the minimum width of the elongated hole. When the disk shaft 122 tends to separate from the elongated hole, the limit buckle 123 can abut against the connecting member 130, thereby preventing the disk shaft 122 and the elongated hole from separating relative to each other.

[0049] Specifically, the limiting buckle 123 is detachably connected to the disk shaft 122, thereby facilitating maintenance of the disk shaft 122. The specific connection method can be a threaded connection, a snap connection, etc., and there is no limitation on the specific connection method of the two.

[0050] Furthermore, the limiting buckle 123 may be a disc-shaped or rectangular parallelepiped structure, and its specific shape is not limited.

[0051] refer to Figure 1 The connecting member 130 includes a transmission plate 131, an extension plate 132, and a support base 133, which are connected in sequence. The transmission plate 131 has an adjustment portion 1301 that flexibly cooperates with the eccentric disc 120. The pressure roller 140 is coaxially connected to the support base 133. To enable relative rotation between the pressure roller 140 and the support base 133, the support base 133 can be connected to the pressure roller 140 via a bearing. Furthermore, the coaxial connection between the support base 133 and the pressure roller 140 improves the synchronization of the movement of the pressure roller 140 and the support base 133.

[0052] It can be understood that the elongated holes or elongated slots are formed on the transmission plate 131 , and the transmission plate 131 is in a rectangular structure, with its long side direction parallel to the long extension direction of the elongated holes or elongated slots.

[0053] refer to Figure 1 In order to prevent the pressure roller 140 from being deflected during the adjustment process, the number of the driving member 110, the eccentric disk 120 and the connecting member 130 can be two groups, and the two groups of connecting members 130 are respectively connected to the two ends of the pressure roller 140.

[0054] That is, the power sources 111 in the two driving members 110 communicate with each other, so that the actions of the two power sources 111 are synchronized, and the movements of the two ends of the pressure roller 140 are also synchronized, preventing the pressure roller 140 from being skewed relative to the active roller 200, so as to ensure the uniform distribution of the clamping force at different positions in the axial direction of the pressure roller 140.

[0055] An embodiment of the present invention further provides a laminating machine, including a feeding mechanism, an active roller 200 and a pressure adjustment mechanism 100 , wherein the active roller 200 is arranged parallel to the pressure roller 140 , and the feeding mechanism is used to convey the material strip between the active roller 200 and the pressure roller 140 .

[0056] During operation, the feeding mechanism is used to convey the material strip, which can pass between the active roller 200 and the pressure roller 140. The active roller 200 is used to rotate, while the pressure roller 140 is close to the active roller 200. By adjusting the relative distance between the pressure roller 140 and the active roller 200, the passing material strip can be squeezed to output a material strip that meets production requirements. The laminating machine includes a pressure adjustment mechanism 100, which has all the functions of the pressure adjustment mechanism 100.

[0057] In summary, the pressure adjustment mechanism 100 and the laminating machine provided by the embodiments of the present invention have at least the following advantages:

[0058] (1) It can drive the pressure roller 140 to move linearly through the active cooperation of the eccentric disk 120 and the connecting member 130, so that the pressure roller 140 is close to or away from the active roller 200. Compared with the linear drive, it can achieve precise adjustment of the position of the pressure roller 140, ensuring that the pressing force applied by the pressure roller 140 on the active roller 200 is more accurate.

[0059] (2) A limiting buckle 123 can be provided at the end of the disk shaft 122 away from the disk body 121. The size of the limiting buckle 123 is larger than the minimum width of the elongated hole, so that when the disk shaft 122 has a tendency to move away from the elongated hole, the limiting buckle 123 can limit it to prevent the disk shaft 122 and the elongated hole from being relatively separated.

[0060] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
