Description

Technical Field

[0001] The utility model relates to the technical field of production and manufacturing of paper-based materials, in particular to infrared heat-sealing and bonding equipment for paper-based materials. Background Art

[0002] In the prior art, the production of paper-based materials requires the use of multiple layers of paper base for heat sealing and bonding. The multiple layers of paper base are pressed and bonded to support the finished product, which can effectively increase the various functions of the paper-based materials such as water resistance, flame retardancy, heat insulation, and sound insulation. At the same time, it can also increase the bonding strength between paper-based materials and improve the service life of the product.

[0003] The heat-sealing bonding equipment of paper-based materials in the prior art is usually configured to press multiple layers of paper-based materials through a pressing device, and the paper-based materials need to be heated during pressing so that the multiple layers of paper-based materials can be bonded together, thereby reducing the production cost.

[0004] However, the usual technical solution in the existing equipment is to set a heating mechanism in the pressure-bearing device at the bottom. When the paper-based material is placed in the work station slot, the pressure-bearing device heats the paper-based material, while the upper pressure device, pressure plate or pressure head, etc., do not heat themselves when pressing. Therefore, during the specific pressing, the paper-based material located on the top layer may be pressed unevenly, the heating temperature is not enough, the temperature is not uniform, etc., which leads to poor heat sealing and bonding effect of the paper-based material, and uneven heat sealing and bonding positions.

[0005] In addition, in the prior art, even if both the pressure-bearing equipment and the pressure equipment are heated, usually a set of heating structure is set on the pressure equipment or the pressure-bearing equipment. If so, two sets of heating mechanisms need to be set up, which increases the cost.

[0006] Therefore, in order to solve the above problems, it is necessary to develop a paper-based material heat-sealing and bonding device with a reasonable structure that can improve work efficiency and work quality. Summary of the invention

[0031] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0032] like Figure 1 As shown, an infrared heat-sealing bonding device for paper-based materials comprises a heat-sealing fixed base 1 and a heat-sealing pressing mechanism; a heat-sealing station slot 2 is arranged on the heat-sealing fixed base 1; the heat-sealing pressing mechanism comprises a pressing device 3 and a heat-sealing movable base 4, and a heat-sealing pressing head 5 corresponding to the position of the heat-sealing station slot 2 is arranged on the heat-sealing movable base 4;

[0033] like Figure 2 As shown, both the heat-sealing movable base 4 and the heat-sealing fixed base 1 are provided with internal hollow thermal grooves 6; and an upwardly protruding circulation convex pipe 7 is also provided at the edge of the heat-sealing fixed base 1, and the circulation convex pipe 7 is correspondingly connected to the thermal grooves 6 in the heat-sealing fixed base 1;

[0034] An inwardly concave circulation concave tube 8 is provided at the edge of the heat-sealing movable base 4, and the circulation concave tube 8 is connected to the thermal groove 6 in the heat-sealing movable base 4, and the position of the circulation concave tube 8 corresponds to that of the circulation convex tube 7, and the tube body size of the circulation convex tube 7 is adapted to the tube body size of the circulation concave tube 8. When the heat-sealing movable base 4 moves downward, the circulation convex tube 7 is correspondingly inserted into the circulation concave tube 8;

[0035] The thermal tank 6 of the heat-sealing movable base 4 is also connected to a steam device 10 via a steam pipe 9, and a circulation pump 11 is also provided on the steam pipe 9. The hot steam can be delivered from the steam device 10 to the thermal tank 6 through the circulation pump 11, and with the cooperation of the circulation convex pipe 7 and the circulation concave pipe 8, a thermal circulation is formed in the upper and lower thermal tanks 6.

[0036] like Figure 3 As shown, the circulating concave pipe 8 and the circulating convex pipe 7 are both installed with an electric control valve 12 ; and the heat sealing fixed base 1 and the heat sealing movable base 4 are both correspondingly provided with a control mechanism 13 for controlling the electric control valve 12 .

[0037] The electric control valve 12 on the circulation convex pipe 7 is arranged at the bottom of the pipe body; and the electric control valve 12 on the circulation concave pipe 8 is arranged at the upper end of the pipe body accordingly;

[0038] When the circulation convex pipe 7 is inserted into the circulation concave pipe 8, the positions of the electric control valves 12 in the two pipe bodies are independent of each other and will not interfere with each other.

[0039] like Figure 4 As shown, the heat sealing fixed base 1 and the heat sealing movable base 4 are both arranged as circular base structures; the heat sealing station groove 2 and the heat sealing pressure head 5 are both arranged as circular structures; and the circulation concave tube 8 and the circulation convex tube 7 are both arranged with six evenly spaced ones.

[0040] like Figure 5 As shown, support columns 14 are correspondingly arranged in the thermal grooves 6 in the heat-sealing fixed base 1 and the heat-sealing movable base 4; and the support columns 14 are made of heat-resistant material and are evenly spaced in the thermal grooves 6; there are two groups of pressing devices 3, and they are correspondingly arranged as hydraulic mechanisms.

[0041] A circle of annular mounting plates 41 are correspondingly provided on the outside of the heat-sealing movable base 4, and a plurality of evenly spaced infrared auxiliary drying devices 42 are installed on the annular mounting plates 41. The infrared auxiliary drying devices 42 are installed obliquely, and the direction of the infrared rays is correspondingly aligned with the paper-based material 15 in the heat-sealing station slot 2, so that the infrared drying operation can be performed on the paper-based material 15 in the heat-sealing station slot 2.

[0042] The specific working principle of this device is as follows: when the technical solution of this device is working, it is necessary to first place the stacked paper-based materials in the work station slot, and during specific work, the size of the paper-based materials is consistent with the size of the heat sealing work station slot and the heat sealing pressure head, and the form and size can be designed and changed according to the specific paper-based materials.

[0043] The heat-sealing fixed base located below is connected to a heat tank with steam equipment, and hot steam is sent into the heat tank through a circulation pump. The heat-sealing fixed base itself can heat the paper-based material in the station tank.

[0044] Afterwards, the upper heat-sealing movable base moves downward under the action of the downward pressure mechanism. In this process, the circulating convex tube is first inserted upward into the circulating concave tube, and after the positions are inserted accordingly, the electric control valves in the circulating concave tube and the circulating convex tube can be opened by the control device, so that the hot steam in the thermal tank in the heat-sealing fixed base enters into the thermal tank in the upper heat-sealing movable base accordingly, and the circulating pump is also turned on accordingly, so that a thermal circulation can be formed in the upper and lower thermal tanks.

[0045] During the thermal cycle, you can wait for a while until the upper heat-sealing movable base is heated before pressing down for heat sealing; you can also press down after the hot steam directly enters the thermal tank above. After the paper-based material is pressed, heat-sealed adhesion will occur under the action of heat. Since the upper and lower end surfaces of the paper-based material are heated by hot steam, the effect of hot air adhesion will be better and the structure will be more reasonable.

[0046] After the above work is completed, the upper heat-sealing movable base needs to be moved up and away from the lower heat-sealing fixed base. During the separation stage, the circulating convex tube gradually separates from the circulating concave tube, and at the same time, the control mechanism controls the electric control valve in the tube body to close, thereby closing the upper and lower thermal tanks as a whole, and the internal hot steam will not be lost.

[0047] After the above work is completed, the upper heat-sealing movable base can be moved upward accordingly, and then auxiliary drying is carried out through a circle of infrared auxiliary drying devices arranged on the outside, so that the moisture can evaporate faster to achieve the drying purpose. Then the product in the heat-sealing station slot can be taken out, and then the next stage of heat-sealing work can be started. The overall structural setting is very reasonable and effective.

[0048] The finished paper-based material produced by the heat-sealing bonding device of the device has good performance, and the heat-sealing interlayer bonding force is greater than 150j / m 2 ; The oil-proof Kit value is increased by 53%; the water-proof Cobb60 value is increased by 60%; it can realize the integration of multi-level barriers such as heat sealing and barrier; it can realize single coating, double coating and integrated coating of heat sealing barrier, and the oil and water barrier properties are greatly improved.

[0049] The above-mentioned specific implementation mode is only a preferred embodiment of the present invention and is not intended to limit the implementation of the present invention and the scope of the claims. All equivalent changes and modifications made according to the content of the patent protection scope of the present invention should be included in the scope of the patent application of the present invention.
