Description

Technical Field

[0001] This utility model relates to rubber roller adjustment, specifically a rubber roller pressure adaptive mechanism. Background Technology

[0002] In existing technology, the height of the rubber roller in printing equipment usually needs to be adjusted according to the thickness of the workpiece during use, so that the rubber roller can contact the workpiece and process it. Currently, the height adjustment of the rubber roller is usually done manually, and it needs to be adjusted according to the thickness of the workpiece before each processing, which is quite cumbersome.

[0003] Furthermore, if the thickness of the workpiece changes during processing, an increase in thickness will lead to increased pressure on the rubber roller, making it prone to deformation; conversely, a decrease in thickness may result in a gap between the rubber roller and the workpiece, preventing normal operation. Therefore, a rubber roller pressure adaptive mechanism is proposed. Utility Model Content

[0006] A further preferred embodiment includes at least one limiting guide installed on the wall panel to limit and guide the movement of the pressure regulating plate.

[0007] Further preferably, it also includes at least one waist-shaped groove disposed on the pressure regulating plate corresponding to the limiting guide, so that the pressure regulating plate can move based on the limiting guide.

[0008] More preferably, the width of the waist-shaped groove is greater than or equal to the diameter of the limiting guide.

[0019] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly; for example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can also mean a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] See Figures 1-3 As shown: Example 1

[0021] A rubber roller pressure adaptive mechanism includes a wall plate 1, a rubber roller 2 rotatably mounted on the wall plate 1, and a bearing 21 mounted on the end of the rubber roller 2; characterized in that it further includes a pressure adjusting component for automatically adjusting the height of the rubber roller 2 according to the thickness of the workpiece, the pressure adjusting component including a pressure adjusting plate 3 movably connected to the wall plate 1 and in contact with the bearing 21 at the end of the rubber roller 2, and at least one tension spring 4 connecting the pressure adjusting plate 3 and the wall plate 1 for applying a downward force to the pressure adjusting plate 3 to drive the rubber roller 2 to move downward;

[0022] With the setting of this device, the height of the rubber roller 2 can be automatically adjusted according to the thickness of the workpiece during use, so that it can be used for workpieces of different thicknesses. At the same time, it can be adjusted automatically without manual operation, with a wide range of applications and a high degree of automation.

[0023] The tension spring 4 pulls the pressure adjusting plate 3 downward in a straight line, thereby driving the rubber roller 2 to move downward and stick tightly to the workpiece, so that the rubber roller 2 elastically presses against the workpiece.

[0024] In one embodiment, it further includes at least one limiting guide 5 installed on the wall panel 1 to limit and guide the movement of the pressure regulating plate 3. The limiting guide 5 limits and guides the linear movement of the pressure regulating plate 3.

[0025] In one embodiment, it further includes at least one waist-shaped groove 31 disposed on the pressure regulating plate 3 corresponding to the limiting guide 5 so that the pressure regulating plate 3 can move based on the limiting guide 5;

[0026] The width of the waist-shaped groove 31 is equal to the diameter of the limiting guide 5;

[0027] With the waist-shaped groove 31 set, and the width of the waist-shaped groove being the same as the diameter of the limiting guide 5, the pressure regulating plate 3 moves linearly along the limiting guide 5 through the waist-shaped groove 31 when adjusting its up and down position.

[0028] In one embodiment, an arc-shaped groove 32 is provided on the pressure regulating plate 3 to contact and cooperate with the bearing 21. By providing the arc-shaped groove 32, the pressure regulating plate 3 and the bearing 21 are in contact and cooperate. When the pressure regulating plate 3 is in motion, it can drive the bearing 21 to move, and the bearing 21 drives the rubber roller 2 to move accordingly.

[0029] In one embodiment, it also includes a waist-shaped groove 11 provided on the wall panel 1 for adjusting the vertical position of the rubber roller 2 and the bearing 21;

[0030] The waist-shaped groove 11 allows the rubber roller 2 and the bearing 21 to move up and down without interference.

[0031] In one embodiment, a connector 6 is also included, which is installed on the pressure regulating plate 3 and the wall plate 1 to connect the tension spring 4. The tension spring 4 can be directly connected to the pressure regulating plate 3 and the wall plate 1, or the connector 6 can be installed on the pressure regulating plate 3 and the wall plate 1, and then the two ends of the tension spring 4 can be connected to the connector 6.

[0032] In this embodiment, when the rubber roller 2 is in contact with the workpiece, it automatically moves up and down according to the thickness of the workpiece. When the thickness increases, the rubber roller 2 drives the bearing 21 to move upward. The bearing 21 pushes the pressure adjusting plate 3 to move upward during the upward movement. When the pressure adjusting plate 3 moves upward, it moves upward along the limiting guide 5 through the waist-shaped groove 31, and at the same time pulls the tension spring 4.

[0033] When the thickness decreases, the tension of the tension spring 4 pulls the pressure adjusting plate 3 downward, and the pressure adjusting plate 3 applies downward pressure to the bearing 21, which in turn drives the rubber roller 2 to move downward. Example 2

[0034] The difference between this embodiment and embodiment 1 is that there are two limiting guide members 5 in this embodiment. One is movably connected to the pressure regulating plate 3 and serves as the rotation base point when the pressure regulating plate 3 rotates. The other plays a limiting role when the pressure regulating plate 3 rotates. In addition, the width of the waist-shaped groove 31 is greater than the width of the limiting guide member 5, so that the pressure regulating plate 3 can rotate within the set stroke.

[0035] When the rubber roller 2 adjusts its position up and down based on the thickness of the workpiece, when the thickness increases, the rubber roller 2 drives the bearing 21 to move upward. During the upward movement, the bearing 21 applies an upward thrust to the pressure adjusting plate 3. After receiving the upward thrust, the pressure adjusting plate 3 rotates along the rotation base point, and the other end of the pressure adjusting plate 3 pulls the tension spring 4.

[0036] When the thickness decreases, the tension of the tension spring 4 pulls the pressure adjusting plate 3, and the pressure adjusting plate 3 rotates along the rotation base point. When the pressure adjusting plate 3 rotates, it applies downward pressure to the bearing 21, and the bearing 21 drives the rubber roller 2 to move downward accordingly.

[0037] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
