Description

Technical Field

[0001] The invention belongs to the field of corrugated paper production equipment, and in particular relates to corrugated paper steam pre-gelatinization equipment. Background Art

[0002] Based on the requirements of environmental protection, starch adhesive is generally used as the adhesive of the strength fiber mesh in the high-strength corrugated paper production process to bond the strength fiber mesh to the face paper and core paper of the corrugated paper. Existing starch adhesives generally need to be pre-gelatinized. During the pre-gelatinization process, water vapor is used to heat the starch and replenish water.

[0003] When gelatinization is performed by heating, a relatively high temperature must be maintained at all times, and the glued corrugated paper is prone to water loss, thereby reducing the bonding strength. In addition, the existing pre-gelatinization device spreads water vapor from above to perform pre-gelatinization operations. The starch is spread flat, so that the steam can only heat and humidify the surface starch, while the starch inside is prone to uneven heating and less water replenishment. Therefore, choosing a larger steam flow rate and a higher temperature will affect the overall shape of the gelatinized material, causing it to flow on the corrugated paper and affect the bonding position. Therefore, the working efficiency of the entire pre-gelatinization device is poor. Summary of the invention

The hanger 31 is installed in the upper cover part of the equipment frame 1 through the cross beams on both sides. A mounting hole 33 is provided at the geometric center position of the upper surface of the hanger 31. The mounting hole 33 is used to install and connect to the four-corner steam pipe 41 and the gelatinized starch pipe 42, so that these pipes can be uniformly led out through the mounting hole 33. The steam device 4 is installed in the installation hole 33 and the position and number correspond to the installation hole 33 one by one. The steam device 4 includes a four-corner steam pipe 41 and a gelatinized starch pipe 42. The four-corner steam pipe 41 is fixed on the four corners of the gelatinized starch pipe 42. The four-corner steam pipe 41 sprays steam from the four corners to uniformly heat the discharged gelatinized material. The recovery preheating structure 5 includes a recovery cover 51, which is provided with multiple pieces. The recovery cover 51 is installed below the recovery box 52 and is spaced apart from the hanger device 3. The recovery cover 51 can recover the steam after use and use it to participate in heat recovery; The wiring structure 6 includes a wire roller 61 and a tensioning roller 62. Both ends of the wire roller 61 are fixedly mounted on the baffle 414. The tensioning roller 61 is located at the lower side of the wire roller 61 and both ends are fixedly mounted on the baffle 414. The wire roller 61 releases a heating wire and passes through the gelatin to heat the gelatin from the inside.

[0020] In this embodiment, the equipment rack 1 includes an electrical structure part 11 and isolation plates 12 located on both sides of the conveyor belt 2 , the isolation plates 12 are located between the electrical structure part 11 and the upper cover part, and the electrical structure part 11 is used to provide support for the equipment rack 1 .

[0021] In this embodiment, guide grooves 34 are provided on both sides of the hanger 31, and limit plates 35 are provided on both sides of the vertical frame 32, and the limit plates 35 are slidably connected in the guide grooves 34. The vertical frame 32 and the hanger 31 are connected by multiple electric push rods 36, and the bottom of the electric push rods 36 is fixed on the lower surface of the hanger 31. The vertical frame 32 and the steam device 4 in the vertical frame 31 can be adjusted up and down by pushing and pulling the electric push rods 36, so that the steam device 4 is moved to a position close to the paste, thereby reducing the waste of steam heat.

[0022] In this embodiment, the four-corner steam pipes 41 are divided into two groups and symmetrically arranged on both sides of the gelatinized starch pipe 42. The four-corner steam pipes 41 in the same group are connected to each other through a transfer plate 43. The four-corner steam pipes 41 are used to spray steam. The two groups of four-corner steam pipes 41 are connected to each other through a heat preservation plate 44 .

[0023] In this embodiment, the four-corner steam pipe 41 includes a steam pipe 411, a blocking slider 412 and a baffle 414. The steam pipe 411 is provided with a pipe for steam circulation. The blocking slider 412 is slidably connected to the bottom of the steam pipe 411. The baffle 414 is fixedly installed at the bottom of the insulation board 44. When steam is introduced into the steam pipe 411, the air pressure will cause the blocking slider 412 to move downward until the blocking slider 412 moves out of the steam pipe 411. Then, the baffle 414 is driven by the electric push rod 36 to press on the corrugated cardboard. The gas ejected from the steam pipe 411 acts on the baffle 414, which can not only concentrate heat but also prevent the corrugated paper from getting damp.

[0024] In this embodiment, a trumpet-shaped discharge port is provided at the bottom outlet of the gelatinized starch tube 42 for discharging the gelatinized material.

[0025] In this embodiment, a cavity is provided in the lower half of the adapter plate 43, and spring plate guide rails 431 are provided on the surfaces of the adapter plate 43 on both sides that are in close contact with the four-corner steam pipes 41. A spring plate 432 that is slidably and guidedly connected to the spring plate guide rail 431 is provided in the spring plate guide rail 431. The bottom of the spring plate 432 is connected to the blocking slider 412. A long plate 434 perpendicular to the spring plate 432 is also provided on the spring plate 432. The long plate 434 is slidably connected to the grooves of the two sides of the adapter plate 43 that are in close contact with the four-corner steam pipes 41. A spring 435 is provided above the spring plate 432. The spring 435 is located above the spring plate 432 and installed in the cavity. After the steam enters the steam pipe 411, the spring plate 432 will be pressed down. At the same time, since the spring 435 uses a light-load spring, the spring plate 432 can be moved downward, so that the blocking slider 412 can be disengaged from the steam pipe 411. At the same time, since a long plate 434 is also provided on the spring plate 432, the lengths of the upper and lower ends of the long plate 434 are designed to exceed the stroke of the blocking slider 412, and the long plate 434 moves up and down in the groove. Therefore, the adapter plate 43 will not cause steam leakage and can also provide guidance for the movement of the blocking slider 412.

[0026] In this embodiment, the recovery box 52 is installed above the hanger device 3, and an exhaust fan 53 is provided on the side of the recovery box 52 located on the entrance side of the equipment rack 1. The air bleed box 51 is connected between the recovery box 52 and the preheating hood 55. The bottom of the preheating hood 55 is installed above the conveyor belt 2 through a vertical plate bracket 56. The vertical plate bracket 56 is installed on the equipment rack 1. The steam sprayed by the steam device 4 is sucked out by the exhaust fan 53. This part of the steam will heat up and pass through the recovery box 52, and finally spray the heat from the preheating hood 55 onto the conveyor belt 2 at the entrance of the equipment rack 1, thereby increasing the surface temperature of the corrugated paper.

[0027] In this embodiment, the wire roller 61 and the tensioning roller 62 both include two groups symmetrically arranged on both sides of the steam device 4. A plurality of wire groups are arranged in the wire roller 61. A heating wire is wound around the wire group. The heating wire passes around the tensioning roller 62 and is tensioned by the tensioning roller 62. A semi-enclosed guide ring 63 is provided on the tensioning roller 62. A humidifying layer is provided in the guide ring 63. A motor is provided at the end of the wire roller 61. Through the circulation action of the motors symmetrically arranged on the wire rollers 61 on both sides, the heating wire can be wound back and forth on the wire rollers on both sides. During the winding process, the inside of the gelatin can be heated by movement. At the same time, the heating layer can make the wire wet when the heating wire passes through, replenish the moisture in the gelatin, and can also play a role similar to that of steel bars in reinforced concrete in the gelatin, reinforcing the surface of the gelatin to prevent it from flowing under the action of steam with wind force.

[0028] Working principle: First, put the corrugated paper on the conveyor belt 2, start the equipment rack 1, and when the conveyor belt 2 enters the equipment rack 1, it moves to the position where the steam device 4 is located, and the four-corner steam pipes 41 spray steam, and the gelatinized starch pipe discharges the gelatinized material. When steam is passed into the steam pipe 411, after the steam enters the steam pipe 411, the spring plate 432 will be pressed down, which will cause the blocking slider 412 to move down until the blocking slider 412 moves out of the steam pipe 411. The gas sprayed from the steam pipe 411 acts on the surface of the gelatinized material under the guidance of the baffle 414. At the same time, due to the The spring 435 is a light-load spring, which can move the spring plate 432 downward and make the blocking slider 412 escape from the steam pipe 411. At the same time, since a long plate 434 is also provided on the spring plate 432, the lengths of the upper and lower ends of the long plate 434 are designed to exceed the stroke of the blocking slider 412, and the long plate 434 moves up and down in the groove. Therefore, the adapter plate 43 will not cause steam leakage and can also provide guidance for the movement of the blocking slider 412. Then, the conveyor belt 2 is moved in sequence according to the interval distance of the steam device 4, and pre-gelatinization is completed under the action of the steam device 4.

It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the inventive concept and technical solution of the present invention, or the inventive concept and technical solution are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
