Description

Technical Field

[0001] This utility model relates to the field of corrugated machine technology, and in particular to a support structure for a corrugated machine sizing assembly. Background Technology

[0002] The current corrugated machine sizing assembly includes a frame plate, the sizing assembly itself, and a movement control mechanism. The frame plate has guide rails, and the sizing assembly rests on these rails via rollers and is controlled to move along them by the movement control mechanism. The sizing assembly comes to rest when it reaches the working position. Because the lower ends of the rollers are in line contact with the top surface of the guide rails, the sizing rollers are close to the corrugating rollers during sizing. Furthermore, combined with the mechanical vibration of the equipment, relative vibration between the sizing assembly and the guide rails is unavoidable. After prolonged use, pits can easily develop on the guide rails where the rollers rest, affecting the positioning of the sizing assembly. Utility Model Content

[0003] The purpose of this utility model is to provide a simple and reasonable corrugated machine sizing assembly support structure in which the sizing assembly contacts and cooperates with the guide rail plate through the support platform during the sizing process, thereby improving the support stability.

[0004] The purpose of this utility model is achieved as follows:

[0005] A corrugated machine sizing assembly support structure includes a frame plate, a sizing assembly, and a movement control mechanism. The frame plate is equipped with guide rails, and the sizing assembly rests on the guide rails and is controlled to move along the guide rails by the movement control mechanism. The sizing assembly has rollers and a support platform above the support surface corresponding to the guide rails. The sizing assembly also has a lifting adjustment mechanism for controlling the relative height between the lower end of the rollers and the lower end face of the support platform. When the sizing assembly needs to move on the guide rails, the lifting adjustment mechanism controls the lower end of the rollers to be lower than the lower end face of the support platform. When the sizing assembly needs to remain relatively stationary with respect to the guide rails, the lifting adjustment mechanism controls the lower end of the rollers to be higher than or equal to the lower end face of the support platform, with the lower end face of the support platform resting on the guide rails.

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0030] See Figures 1 to 8 As shown, a corrugated machine sizing assembly support structure includes a frame plate 1, a sizing assembly 3, and a movement control mechanism 4. The frame plate 1 is provided with a guide rail 11, and the sizing assembly 3 is supported on the guide rail 11 and its movement on the guide rail 11 is controlled by the movement control mechanism 4. The sizing assembly 3 has a roller 34 and a support platform 32 above the support surface corresponding to the guide rail 11. The sizing assembly 3 is also provided with a lifting adjustment mechanism for controlling the relative height between the lower end of the roller 34 and the lower end face of the support platform 32. When the sizing assembly 3 needs to move on the guide rail 11, the lifting adjustment mechanism controls the lower end of the roller 34 to be lower than the lower end face of the support platform 32. When the sizing assembly 3 needs to be stationary relative to the guide rail 11, the lifting adjustment mechanism controls the lower end of the roller 34 to be higher than or equal to the lower end face of the support platform 32, with the lower end face of the support platform 32 resting on the guide rail 11.

[0031] The lower end of the support platform 32 is provided with a wear-resistant plate 33.

[0032] The lifting and adjusting mechanism includes an eccentric shaft 35, the two ends of which are rotatably connected to the sizing assembly 3 and the roller 34, respectively.

[0033] The roller 34 is provided with two sets, front and rear, and the support platform 32 is located between the two sets of rollers 34.

[0034] The movement control mechanism 4 is a hydraulic cylinder. The two ends of the hydraulic cylinder are respectively hinged to the frame plate 1 and the sizing assembly 3.

[0035] The sizing assembly 3 includes a sizing hopper, a sizing control roller, a sizing roller, and two end plates 31 on the left and right. The sizing hopper, the sizing control roller, and the sizing roller are respectively arranged between the two end plates 31. The two end plates 31 are each provided with the roller 34 and the support platform 32.

[0036] The frame plate 1 is also provided with a corrugated roller group. The movement control mechanism 4 is used to control the sizing roller of the sizing assembly 3 to approach the corrugated roller group. When the distance between the sizing roller and the corrugated roller group meets the requirements, the sizing assembly 3 is supported on the guide rail 11 through the lower end face of the support platform 32.

[0037] The corrugated roller assembly includes a main corrugated roller 22, a secondary corrugated roller 21, and a pressure roller 23. The secondary corrugated roller 21, the sizing roller, and the pressure roller 23 are arranged in this order around the main corrugated roller 22 along the rotation direction of the main corrugated roller 22.

[0038] The hydraulic cylinder is parallel to the guide rail 11. An air bladder 5 is also provided between the sizing assembly 3 and the frame plate 1, providing a force opposite to that of the hydraulic cylinder. In this embodiment, one end of the air bladder 5 is connected to the frame plate 1, and the sizing assembly 3 is provided with a baffle corresponding to the other end of the air bladder 5, allowing the sizing assembly 3 to contact the air bladder 5 via the baffle. By adjusting the magnitudes of the forces from the hydraulic cylinder and the air bladder 5, the extrusion pressure between the sizing assembly and the corrugated roller is adjusted to achieve the best production effect.

[0039] Its working principle is: See Figure 1 As shown in the figure, arrows A, B, and C represent the core paper feeding direction, the face paper threading direction, and the corrugated paper exit direction, respectively. When the sizing assembly 3 is in the working position, the eccentric shaft 35 rotates to make the roller 34 leave the guide rail. The wear-resistant plate supports the weight of the sizing assembly and contacts the track plane, resulting in a large contact area, resistance to wear, durability, and smooth operation.

[0040] See Figure 5 As shown, when the sizing assembly 3 is in the non-working position, the roller supports the sizing assembly to contact the guide rail. At this time, the wear-resistant plate leaves the guide rail plane, changing sliding friction to rolling friction, which facilitates the long-distance movement of the sizing assembly and makes maintenance easier.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
