Description

Technical Field

[0001] This utility model relates to the field of corrugating machine technology, and in particular to a balancing system for the sizing assembly of a corrugating machine. 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

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

[0005] A balancing system for a corrugated machine's sizing assembly includes a frame plate, a sizing assembly, and a pushing cylinder. The frame plate is equipped with a guide rail, and the sizing assembly is equipped with rollers that travel on the guide rail. A reaction force device, which is a cylinder or an air bladder, is also provided between the sizing assembly and the frame plate. The cylinder or air bladder provides a force opposite to that of the pushing cylinder.

[0006] The objective of this utility model can also be achieved by the following technical measures:

[0007] As a more specific embodiment, the push cylinder and the reaction force device are located on the upper and lower sides of the sizing assembly, respectively.

[0009] As a further embodiment, one end of the reaction force device is connected to the frame plate, and the other end of the sizing assembly is provided with a baffle corresponding to the reaction force device, so that the sizing assembly abuts against the reaction force device through the baffle.

[0010] As a further embodiment, the push cylinder and the reaction force device are connected to the oil circuit and the air circuit, respectively.

[0011] As a further embodiment, the sizing assembly includes a sizing hopper, a sizing control roller, a sizing roller, and two end plates on the left and right sides. The sizing hopper, the sizing control roller, and the sizing roller are respectively disposed between the two end plates. Each end plate is provided with a roller and a push-pull cylinder. Each end plate is provided with a reaction force device between itself and the corresponding frame plate.

[0012] As a further embodiment, the frame plate is also provided with a corrugated roller assembly, which includes a main corrugated roller, a secondary corrugated roller, and a pressure roller. The secondary corrugated roller, the sizing roller, and the pressure roller are arranged in sequence around the main corrugated roller along the rotation direction of the main corrugated roller.

[0015] The beneficial effects of this utility model are as follows:

[0016] When the sizing assembly of this invention moves toward the corrugated roll group, oil enters the rodless chamber of the left side of the oil cylinder. The force of the oil cylinder pushes the sizing assembly close to the corrugated roll. The air bag enters and generates a force opposite to that of the oil cylinder. By controlling the magnitude of the two forces through the program, the squeezing force between the sizing assembly and the corrugated roll is achieved to achieve the best production effect.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0023] See Figures 1 to 5 As shown, a balancing system for a corrugated machine's sizing assembly includes a frame plate 1, a sizing assembly 3, and a pushing cylinder 4. The frame plate 1 is provided with a guide rail 11, and the sizing assembly 3 is provided with rollers 34, which travel on the guide rail 11. The system is characterized in that a reaction force device 5 is provided between the sizing assembly 3 and the frame plate 1. The reaction force device 5 is an airbag, which provides a force opposite to that of the pushing cylinder 4.

[0024] The push cylinder 4 and the reaction force device 5 are located on the upper and lower sides of the sizing assembly 3, respectively.

[0025] The push cylinder 4 is parallel to the guide rail 11 and points in the direction of the guide rail 11. The two ends of the push cylinder 4 are respectively hinged to the frame plate 1 and the sizing assembly 3.

[0026] One end of the reaction force device 5 is connected to the frame plate 1, and the other end of the sizing assembly 3 is provided with a baffle 311 corresponding to the reaction force device 5. The sizing assembly 3 abuts against the reaction force device 5 through the baffle 311. The frame plate 1 is provided with a mounting base 12, and the reaction force device 5 is mounted on the mounting base 12.

[0027] The push cylinder 4 and the reaction force device 5 are respectively connected to the oil circuit and the air circuit.

[0028] The sizing assembly 3 includes a sizing hopper, a sizing control roller 38, a sizing roller 37, 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. Each end plate 31 is provided with a roller 34 and a push cylinder 4. Each end plate 31 is provided with a reaction force device 5 between itself and the corresponding frame plate 1.

[0029] The frame plate 1 is also equipped with a corrugated roller group, which 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. The push cylinder 4 is used to control the sizing roller to move closer to the main corrugated roller 22.

[0030] Two sets of push-up cylinders 4 are connected in parallel, and two sets of reaction force devices 5 are connected in parallel.

[0031] The rollers 34 are connected to the end plates 31 via eccentric shafts. Each end plate has two sets of rollers 34, one in front and one behind. A support platform 32 is provided between the two sets of rollers on the end plate. When the slurry assembly 3 needs to move on the guide rail 11, the rollers 34 are lowered (e.g., ...). Figure 4 (As shown); when the sizing assembly 3 needs to be stationary relative to the guide rail 11, the roller 34 is raised, and the lower end face of the bearing platform 32 rests on the guide rail 11 (as shown). Figure 1 (As shown).

[0032] Its working principle is: See Figure 1 As shown in the diagram, 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 moves towards the corrugated roll group, oil enters the rodless chamber of the left side of the hydraulic cylinder 4. The force of the hydraulic cylinder pushes the sizing assembly close to the corrugated roll. The air bladder generates a force opposite to that of the hydraulic cylinder. By controlling the magnitude of the two forces through the program, the squeezing pressure between the sizing assembly and the corrugated roll is achieved to achieve the best production effect.
