Description

Technical Field

[0001] The invention belongs to the technical field of corrugated board production, in particular to a uniformly heated board machine for producing corrugated board. Background Art

[0002] Corrugated cardboard is a material consisting of at least three layers of paper, mainly used for packaging and transporting items. It is usually composed of two layers of flat paper and a layer of wavy corrugated paper core. The wavy design gives the cardboard good strength and rigidity, which can effectively protect the items inside.

[0003] For example, the utility model with the publication number CN217532105U belongs to the technical field of corrugated board production equipment, especially a hot plate machine for corrugated board production. In view of the problem that the moisture generated by the existing corrugated paper during continuous drying is easily condensed on the inner wall of the chassis, which affects the subsequent production and is not convenient for uniformly heating corrugated paper of different thicknesses, the following scheme is proposed, which includes a chassis, a baffle is fixedly connected to the top of the chassis, a cylinder is fixedly connected to the outer wall of the baffle, an I-type plate is fixedly connected to the bottom of the output end of the cylinder, two vertical plates are fixedly connected to the outer wall of the I-type plate, a rotating roller is rotatably connected between the two vertical plates, and a support rod is fixedly connected to the inner wall of the chassis. The electric heating wire of the utility model removes moisture in the airflow and heats the airflow at the same time. The airflow enters the heating roller through a rotary joint, and the corrugated paper is uniformly heated by the heating roller;

[0004] When the above device is in use, the effect of uniform heating is achieved through the cooperation between the heating component and the dehumidification component and other structures. However, since the corrugated cardboard usually contains a certain amount of moisture, if the hot plate machine is not preheated in advance before entering the hot plate machine, the unpreheated hot plate machine will need to be heated from room temperature. During the heating process, the heat transfer efficiency is low, and the evaporation rate of the moisture in the cardboard is slow, resulting in a significant extension of the drying time of the cardboard in the hot plate machine, which will not only reduce the production efficiency, but also may cause the interruption of the production process and affect the overall production progress. When the above device is in use, due to the large inlet and outlet gaps and the heating by the electric heating wire, the heat radiation in the box will be directly dissipated to the external environment through the gaps. In addition to being transferred to the air by convection, the heat generated by the electric heating wire will also be dissipated to the surroundings in the form of heat radiation. The opening of the inlet and outlet allows the heat radiation to be dissipated outward without hindrance, further aggravating the heat loss, thereby affecting the preheating speed and efficiency, and further reducing the overall production efficiency of the corrugated cardboard. Therefore, a uniform hot plate machine for corrugated cardboard production is proposed to solve the problems raised in the background technology. Summary of the invention

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figures 1 to 6 As shown, the present invention provides a uniform heating plate machine for corrugated board production, comprising an outer box 1, three groups of guide rollers 2 are movably connected inside the outer box 1, two groups of heating components 3 are fixedly connected inside the outer box 1, a first motor 4 is fixedly connected to the top of the outer box 1, a moving component 5 is movably connected inside the outer box 1, baffles 6 are movably connected to both sides of the outer box 1, a second motor 7 is fixedly connected to one side of the outer box 1, a second gear 9 is fixedly connected to the output shaft end of the second motor 7, correction components 8 are movably connected to both sides of the inner part of the outer box 1, and a dehumidification component 10 is arranged outside the outer box 1 away from the second motor 7;

[0031] The heating assembly 3 includes a jet box 31, and a temperature sensor 32 is arranged inside the jet box 31;

[0032] The moving assembly 5 includes a first connecting rod 51 . The two ends of the first connecting rod 51 are hinged to second connecting rods 52 . The opposite ends of the two second connecting rods 52 are hinged to limit plates 53 . The surface of the limit plates 53 is provided with an inclined groove 54 .

[0033] The above scheme is adopted: when the first motor 4 rotates, the first connecting rod 51 is driven to rotate, so that the first connecting rod 51 drives the two limit plates 53 to move in opposite directions through the two second connecting rods 52, and then the baffle 6 moves downward along the trajectory of the inclined groove 54. After the two baffles 6 move downward, the inlet and outlet of the outer box 1 are sealed respectively, thereby reducing the influence of the external cold air on the internal temperature of the outer box 1, so that the outer box 1 can reach the required working temperature faster under the heating of the heating component 3, thereby improving the preheating efficiency and speed.

[0034] like Figure 2 , Figure 5 and Figure 6 As shown, the correction assembly 8 includes a rotating drum 81, the inner wall of which is provided with a first gear 82, the outer wall of which is fixedly connected with a guide groove 83, which is meshingly connected with the second gear 9, the first gear 82 is corrugated, the interior of the rotating drum 81 is movably connected with a round rod 84, the outer wall of which is fixedly connected with two protrusions 85, which are movably clamped in the interior of the round rod 84.

[0035] The above scheme is adopted: when the second motor 7 is running, the second gear 9 is driven to rotate, and the second gear 9 is meshed and connected with the guide groove 83, so that the guide groove 83 drives the rotating drum 81 to rotate, and the first gear 82 is corrugated, so that when the rotating drum 81 rotates, the protrusion 85 drives the round rod 84 to move horizontally back and forth along the trajectory of the first gear 82, and then the round rod 84 drives the push plate 86 to push the side wall of the corrugated cardboard, thereby ensuring that the cardboard maintains a central position during the feeding process, avoiding quality problems caused by position deviation, and thus improving the production quality and efficiency of the corrugated cardboard.

[0036] like Figure 2 , Figure 5 and Figure 6 As shown, the opposite ends of the two round rods 84 are fixedly connected with push plates 86, and the push plates 86 are L-shaped. The inner wall of the outer box 1 is provided with a square groove for limiting the push plates 86 in the horizontal direction. The push plates 86 are made of high-temperature alloy material. When the rotating drum 81 rotates, it drives the protrusion 85 to slide along the trajectory of the first gear 82. When the protrusion 85 slides, it drives the push plates 86 to move toward the direction close to the heating component 3 through the round rods 84.

[0037] The above scheme is adopted: the push plate 86 is made of a high-temperature alloy material. Its function is that, since the high-temperature alloy material can maintain high strength and hardness in a high-temperature environment, and this type of alloy has good oxidation resistance and thermal stability, it can make the push plate 86 less likely to deform, soften, etc. at high temperatures, and thus can continuously and stably push the corrugated cardboard left and right to ensure the normal operation of the device.

[0038] like Figures 2 to 4 As shown, the first connecting rod 51 rotates with the center point as the axis, and the inner wall of the outer box 1 is provided with a sliding groove for limiting the limit plate 53 in the horizontal direction. When the first connecting rod 51 rotates, the two limit plates 53 are driven to move toward each other through the second connecting rod 52. Both ends of the top of the baffle 6 are provided with convex rods. In the initial state, the convex rods are movably connected to the bottom of the inner cavity of the inclined groove 54. The inner wall of the outer box 1 is provided with a limiting groove for limiting the baffle 6 in the vertical direction. Inlet and outlet are respectively provided on both sides of the outer box 1. In the initial state, the two baffles 6 seal the inlet and outlet respectively. After the limit plate 53 moves, it drives the convex rod on the baffle 6 to slide upward along the trajectory of the inclined groove 54. After the baffle 6 moves up, the seal on the outer box 1 is released.

[0039] The above scheme is adopted: the outer box 1 is sealed by the baffle 6 in the initial state. Its function is that the baffle 6 seals the outer box 1. In addition to improving the preheating effect and efficiency, it can also prevent external dust and impurities from entering the interior of the outer box 1 through the inlet and outlet when the device is not in use, and then adhere to the parts inside the outer box 1. The sealing of the outer box 1 by the baffle 6 can reduce the equipment failure rate and thus increase the service life of the equipment.

[0040] like Figures 2 to 3 As shown, there are two guide rollers 2 and two heating components 3, the two guide rollers 2 rotate in opposite directions, the second gear 9 is fixedly connected to the axis of one end of one of the guide rollers 2, the jet box 31 is located between the two guide rollers 2, and a plurality of jet holes 33 are provided on opposite sides of the two jet boxes 31, and the dehumidification component 10 includes an exhaust fan and an air pipe connected to the interior of the outer box 1.

[0041] The above scheme is adopted: through the design of the dehumidification component 10, its function is that when the corrugated cardboard is heated in the outer box 1, the moisture in the cardboard will evaporate to form water vapor. Through the design of the dehumidification component 10, the humid air in the outer box 1 is extracted, and the dry air from the outside is introduced, so as to accelerate the circulation of air and the discharge of moisture, thereby achieving the dehumidification effect and preventing the water vapor from re-condensing on the surface of the corrugated cardboard.

[0042] The working principle and use process of the present invention are as follows: the operator issues an operation command to the heating component 3 through the remote control system, and then the jet box 31 heats the steam transported from the outside and sprays it into the outer box 1 through the jet hole 33. At the same time, the temperature sensor 32 monitors the temperature change during the heating process in real time. Since the two baffles 6 seal the inlet and outlet on both sides of the outer box 1 in the initial state, the influence of the external cold air on the internal temperature of the outer box 1 can be reduced, so that the outer box 1 can reach the required working temperature faster under the heating of the heating component 3, thereby improving the preheating efficiency.

[0043] When the temperature sensor 32 detects that the temperature reaches a predetermined value, the temperature sensor 32 converts the temperature signal into an electrical signal and transmits it to the information terminal, so that the controller of the information terminal issues a command to the first motor 4 to rotate half a circle. The first motor 4 drives the first connecting rod 51 to rotate while running, so that the two limiting plates 53 are pulled toward each other by the two second connecting rods 52, and the convex rod at the top of the baffle 6 slides along the track of the inclined groove 54. Since a limiting groove matching the baffle 6 is provided inside the outer box 1, the convex rod can only drive the baffle 6 to move upward along the track of the inclined groove 54, and the two baffles 6 respectively release the seals on the inlet and outlet on both sides of the outer box 1.

[0044] Subsequently, the operator starts the second motor 7 and puts the corrugated cardboard into the outer box 1, and the three sets of guide rollers 2 rotate under the action of external force, so that the corrugated cardboard moves inside the outer box 1 under the guidance of the guide rollers 2, and heats the corrugated cardboard through the heating component 3. The second motor 7 drives the second gear 9 to rotate while rotating, and through the engagement of the second gear 9 with the guide groove 83, the rotating drum 81 is driven to rotate, and then the protrusion 85 slides along the trajectory of the first gear 82. Since the inner wall of the outer box 1 is provided with a square groove for limiting the push plate 86, the protrusion 85 can only drive the round rod 84 and the push plate 86 thereon to move horizontally back and forth. During the reciprocating movement of the two push plates 86, the two sides of the corrugated cardboard will be continuously pushed, thereby ensuring that the cardboard maintains a central position during the feeding process, avoiding quality problems caused by position deviation, and thus improving the production quality and efficiency of the corrugated cardboard.

[0045] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
