DETAILED DESCRIPTION

[0017] To further illustrate the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes, the specific implementation, structure, features and effects according to the utility model are described in detail as follows by combining with the drawings and preferred embodiments.

[0018] Example 1:

[0019] As Figures 1-6The utility model discloses a kind of adhesion compression devices of corrugated board, including a box 1, paperboard inlet 2 and paperboard outlet 3 are respectively arranged on the opposite two side walls of box 1, two installation strips 17 are arranged on the bottom inside box 1, the installation strip 17 extends from the one end of paperboard inlet 2 to the one end of paperboard outlet 3, rubber block is arranged above the installation strip 17 close to the one end of paperboard inlet 2, a support plate 8 is horizontally arranged on the rubber block, ultrasonic vibrator 9 is arranged on the lower surface of support plate 8, a plurality of support guide rollers 18 are arranged at intervals between installation strip 17, sprocket 5 is arranged in one end of support guide roller 18, drive motor 4 is arranged on the bottom of box 1, sprocket 5 is arranged on the output shaft of drive motor 4, and sprocket 5 of drive motor 4 is connected by chain 6 transmission between the end of support guide roller 18;Vertical slide rail 19 is arranged on the side wall of box 1 at the two ends of each support guide roller 18 and the two ends of support plate 8, sliding frame 10 is arranged on slide rail 19, and pressure roller 13 is rotatably arranged on each sliding frame 10, the pressure roller 13 corresponds to corresponding support guide roller 18, support plate 8, and vertical downward hydraulic cylinder 15 is arranged on the top of box 1 at the corresponding place of each sliding frame 10, and the telescopic end of hydraulic cylinder 15 is connected with sliding frame 10.

[0020] The installation strip 17 in the box 1 is located at the two ends of paperboard inlet 2, and the two are arranged in parallel, support guide roller 18 is arranged on installation strip 17, and support guide roller 18 is driven to rotate synchronously by drive motor 4. Specifically: sprocket 5 is arranged at the end of support guide roller 18, the size of sprocket 5 is the same, drive motor 4 is arranged on the bottom of box 1 at one end, sprocket 5 is also arranged on the output shaft of drive motor 4, and all sprocket 5 is connected by chain 6 transmission, so that drive motor 4 can drive all support guide rollers 18 to rotate synchronously. Of course, all support guide rollers 18 are at the same horizontal height. The hydraulic cylinder 15 on the top of box 1 can drive each sliding frame 10 to rise and fall on slide rail 19, so as to change the height of pressure roller 13, adapt to the compression degree of corrugated board.

[0021] When the corrugated paperboard coated with glue is input from the paperboard inlet 2 to the support plate 8, the pressure roller 13 is used to press the corrugated paperboard, and then the corrugated paperboard is pushed forward by the support guide roller 18 and the pressure roller 13 until the corrugated paperboard is output from the paperboard outlet 3. In this process, the corrugated paperboard coated with glue needs to be transported from the paperboard inlet to the contact between the paperboard and the first support guide roller 18 by a front-end device such as a mechanical hand or by manual operation, and the support guide roller 18 provides power for the forward transportation of the corrugated paperboard. At the same time, the ultrasonic vibrator 9 vibrates the plate body during the entire transportation process. Since the corrugated paperboard is pressed on the support plate 8 by the pressure roller 13 during the transportation process, the vibration of the plate body is transmitted to the corrugated paperboard. The glue inside the corrugated paperboard coated with glue is uniformly dispersed during the vibration process, so that the glue is more uniformly distributed, and the glue is more easily penetrated into the paperboard, thereby improving the adhesion strength.

[0022] The ultrasonic vibrator 9 is generally a commercially available product, which mainly includes an ultrasonic generator and a transducer, and the specific structure is not limited.

[0023] The guide holes in the vertical direction are arranged at both ends of the sliding frame 10, the guide rods 11 are slidably connected in the guide holes, the shaft seats 12 are fixedly arranged at the lower ends of the guide rods 11, the pressure rollers 13 are arranged between the shaft seats 12 at both ends of the same sliding frame 10, the pressure rollers 13 are rotatably arranged on the shaft seats 12, the compression springs 14 are sleeved on the guide rods 11 between the shaft seats 12 and the sliding frame 10, and the two ends of the compression springs 14 are fixedly connected with the shaft seats 12 and the sliding frame 10.

[0024] In order to control the pressing force of the pressure roller 13 on the corrugated paperboard, the guide rods 11 are arranged on the sliding frame 10, the pressure rollers 13 are arranged on the shaft seats 12 at the bottom of the guide rods 11, and the compression springs 14 are arranged between the shaft seats 12 and the sliding frame 10. In actual work, when the pressure roller 13 does not contact the corrugated paperboard during the downward movement of the sliding frame 10 driven by the hydraulic cylinder 15, the compression spring 14 is in a stretched state and bears the weight of the pressure roller 13 and the shaft seat 12. When the hydraulic cylinder 15 continues to move downward after contacting the corrugated paperboard, the tension of the compression spring 14 gradually decreases until it is zero, and the pressure on the corrugated paperboard is the sum of the weights of the pressure roller 13, the shaft seat 12 and the guide rod 11. If it is necessary to continue to increase the pressure according to actual needs, the hydraulic cylinder 15 continues to press down, and at this time the compression spring 14 generates pressure on the shaft seat 12, thereby increasing the pressure of the pressure roller 13 on the corrugated paperboard. The arrangement of the compression spring 14 can effectively control the gradual increase of the pressure on the corrugated paperboard to achieve buffering and avoid damage to the corrugated paperboard.

[0025] A heating element 16 is arranged inside the box 1. The heating element 16 inside the box 1 can be an electric heating tube, which can increase the temperature inside the box 1 when started, so that the glue is easier to solidify, the efficiency of pressing is improved, and the solidification time is reduced.

[0026] A concave hole is arranged on the mounting strip 17 near one end of the paperboard inlet 2, and a rubber block inserted into the concave hole is a rubber column 7. The top end of the rubber column 7 is exposed outside the mounting strip 17, and the support plate 8 is fixed to the top of the rubber column 7. In this embodiment, the rubber block is a rubber column 7, the rubber column 7 is inserted into the concave hole, and the support plate 8 is fixed to the rubber column 7. When the ultrasonic vibrator 9 vibrates, the support plate 8 can produce slight displacement, so that the vibration is better transmitted to the paperboard, and the vibration effect is improved.

[0027] The diameter of the concave hole is 0.5 cm larger than the diameter of the rubber column 7. The rubber column 7 has a small gap inside the concave hole, which can effectively increase the amplitude of vibration and improve the vibration efficiency of the corrugated paperboard.
