Description

Technical Field

[0001] The utility model belongs to the technical field of papermaking equipment, in particular to a gluing section for improving the structural strength of special paper. Background Art

[0002] Specialty paper is a kind of paper with special properties and uses made of specific fiber materials. These fiber materials can be natural, such as wood, grass, hemp, etc., or artificial, such as polyester fiber, nylon fiber, etc. Specialty paper has a wide range of applications, such as packaging, printing, electronics, construction, medical, etc. For example, pearlescent paper can be used for high-end packaging and greeting cards; sulfate paper can be used for printing engineering drawings and maps; thermal paper can be used for cash registers and fax machines; anti-counterfeiting paper can be used for anti-counterfeiting labels and currency, etc.

[0003] During the gluing process, the main purpose of heating specialty paper is to melt or soften the adhesive so that the papers can be better bonded together. Specifically, the adhesive will melt or soften after being heated, allowing it to better penetrate into the fibers of the paper and form a stronger bond. At the same time, heating can also accelerate the curing process of the adhesive, allowing it to reach the required strength for bonding more quickly. It should be noted that the heating process also needs to control the temperature and time to avoid problems such as excessive heating causing paper deformation or adhesive decomposition. Therefore, in actual operation, it is necessary to select the appropriate temperature and time based on factors such as the type of paper, the properties of the adhesive, and the required bonding strength. In short, the main purpose of heating specialty paper during the gluing process is to melt or soften the adhesive and accelerate its curing process to improve the bonding force and achieve the required bonding strength.

[0004] Specialty papers often require heat during the gluing process. The gluing process requires the adhesive to melt or soften so it can bond with the paper's fibers. Heat can speed up this process, allowing the adhesive to penetrate the paper's fibers more quickly and form a stronger bond.

[0005] In the prior art, the heating of paper is only directional heating, which results in uneven heating temperature of paper in a certain space, thereby affecting the structural strength after gluing. Utility Model Content

[0006] In order to solve the problem that the heating direction of paper is only directional, resulting in uneven heating and affecting the structural strength of paper, the utility model provides a gluing section for improving the structural strength of special paper.

[0007] The utility model is realized by the following technical solutions:

[0008] A gluing section for improving the structural strength of special paper comprises a frame, a conveying mechanism for driving the material to be processed is arranged on the table of the frame, a gluing box is arranged above the conveying mechanism, the gluing box spans the conveying mechanism and is installed on the frame; a heating mechanism and a gluing mechanism are arranged in sequence on the inner bottom surface of the gluing box along the material incoming direction;

[0009] The heating mechanism comprises an air outlet nozzle, which is rotatably connected and arranged at the bottom end of a hot air pipe, and the hot air pipe is installed on the gluing box.

[0010] The gluing box spans over the conveying mechanism to form a relatively sealed space, which is helpful for the heat gluing of the paper; the air outlet is rotatably set on the hot air pipe, and by continuously adjusting the direction of the air outlet, the temperature uniformity in the space can be improved, thereby enhancing the structural strength of the paper after gluing.

[0011] A further improvement of the utility model is that the air outlet nozzle and the inner top surface of the gluing box are further connected with a tension spring, and a vibration mechanism is provided in the middle section of the tension spring. The vibration mechanism is connected to an external power source to generate vibration, and the vibration is transmitted through the tension spring and drives the air outlet nozzle to form disordered random rotation, thereby improving the bottleneck of only directional heating.

[0012] A further improvement of the utility model is that the air outlet is connected to the hot air pipe through an adjusting pipe; the two ends of the adjusting pipe are rotatably connected to the hot air pipe and the air outlet respectively. The adjusting pipe helps to increase the wind direction coverage of the air outlet.

[0013] A further improvement of the utility model is that the two ends of the above-mentioned regulating tube are respectively provided with regulating balls; the bottom end of the hot air tube is provided with a threaded section capable of accommodating the regulating ball, the threaded section is provided with a plurality of notches, and the regulating tube is sleeved with a nut ring capable of cooperating with the threaded section to fix the regulating tube. The nut ring cooperates with the threaded section to fix the upper end of the regulating tube, thereby achieving a certain control and management of the general area of ​​the air outlet direction.

[0014] A further improvement of the utility model is that the diameter of the adjusting ball at the lower end of the adjusting tube is between the diameter of the adjusting ball at the upper end of the adjusting tube and the diameter of the adjusting tube, which is helpful to realize the installation of the nut ring on the adjusting tube.

[0015] A further improvement of the utility model is that the above-mentioned air outlet nozzles are provided in plurality, and the plurality of air outlet nozzles are distributed along a direction perpendicular to the moving direction of the conveying mechanism, thereby increasing the coverage of the space inside the gluing box.

[0016] It can be seen from the above technical scheme that the beneficial effects of the utility model are: the gluing box spans above the conveying mechanism, thereby forming a relatively sealed space, which is conducive to the heating and gluing of paper; the air outlet is rotatably set on the hot air pipe, and by continuously adjusting the direction of the air outlet, the temperature uniformity acting on the space can be improved, so as to enhance the structural strength of the paper after gluing.

DETAILED DESCRIPTION

[0024] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0025] As attached Figure 1-5As shown, a gluing section for improving the structural strength of special paper includes a frame 1, a conveying mechanism 2 for moving the material to be processed is provided on the table top of the frame 1, a gluing box 31 is above the conveying mechanism 2, and the gluing box 31 spans the conveying mechanism 2 and is installed on the frame 1; a heating mechanism 6 and a gluing mechanism 5 are provided in sequence on the inner bottom surface of the gluing box 31 along the direction of incoming materials.

[0026] The heating mechanism 6 includes an air outlet 62, which is rotated and connected to the bottom end of the hot air pipe 4, and the hot air pipe 4 is installed on the gluing box 31. There are multiple air outlets 62, and the multiple air outlets 62 are distributed along a direction perpendicular to the moving direction of the conveying mechanism 2. The coverage of the space in the gluing box 31 is increased.

[0027] The air outlet nozzle 62 is connected to the hot air pipe 4 through the regulating tube 61; the two ends of the regulating tube 61 are rotatably connected to the hot air pipe 4 and the air outlet nozzle 62 respectively. The regulating tube 61 helps to increase the wind direction coverage of the air outlet nozzle 62.

[0028] The two ends of the regulating tube 61 are respectively provided with regulating balls 611; the bottom end of the hot air tube 4 is provided with a threaded section 41 capable of accommodating the regulating ball 611, and the threaded section 41 is provided with a plurality of notches, and the regulating tube 61 is sleeved with a nut ring 42 capable of cooperating with the threaded section 41 to fix the regulating tube 61. The nut ring 42 cooperates with the threaded section 41 to fix the upper end of the regulating tube 61, thereby achieving a certain control and management of the approximate area of ​​the air outlet direction.

[0029] The two regulating ball parts 611 are respectively provided with channels communicating with the inside of the regulating tube 61 to achieve gas circulation.

[0030] The diameter of the adjusting ball portion 611 at the lower end of the adjusting tube 61 is between the diameter of the adjusting ball portion 611 at the upper end of the adjusting tube 61 and the diameter of the adjusting tube 61. This helps to achieve the installation of the nut ring 42 on the adjusting tube 61. At the same time, the adjusting ball portion 611 at the lower end of the adjusting tube 61 is sleeved with the air outlet 62 to achieve rotation.

[0031] The tail of the air outlet 62 is connected to the inner top surface of the gluing box 31 with a tension spring 63, and the middle section of the tension spring 63 is provided with a vibration mechanism 64. The vibration mechanism 64 is connected to an external power source to generate vibration, and the vibration is transmitted through the tension spring 63 and drives the air outlet 62 to form a disordered random rotation, thereby improving the bottleneck of only directional heating.

[0032] In summary, the operating principle of the device is as follows: the adjusting ball portion 611 on the upper portion of the adjusting tube 61 extends into the threaded tube 41, and after the nut ring 42 and the threaded section 41 are matched, the adjusting tube 61 is connected to the hot air pipe 4, and the adjusting ball portion 611 on the upper portion of the adjusting tube 61 is supported, so that the adjusting ball portion 611 on the upper portion of the adjusting tube 61 can be flexibly rotated on the hot air pipe 4;

[0033] Finally, with the use of the vibration mechanism 64, the tension spring 63 transmits the amplitude to the air outlet nozzle 62, so that the air outlet nozzle 62 rotates randomly at the lower end of the adjustment tube 61, achieving a uniform heating effect in the space.

[0034] The rotational resistance of the upper end of the adjusting tube 61 on the hot air pipe 4 is controlled by coordinating the tightening degree of the nut ring 42 and the threaded section 41, so that the rotational resistance between the upper part of the adjusting tube 61 and the hot air pipe 4 is greater than the rotational resistance between the lower part of the adjusting tube 61 and the air outlet nozzle 62; the purpose is to adjust the blowing area of ​​the air outlet nozzle 62 by operating the angle between the adjusting tube 61 and the hot air pipe 4.

[0035] The utility model discloses a gluing section for improving the structural strength of special paper. The gluing box spans above the conveying mechanism to form a relatively sealed space, which is helpful for the heated gluing of the paper. The air outlet is rotatably arranged on the hot air pipe. By continuously adjusting the direction of the air outlet, the temperature uniformity acting on the space can be improved, so as to improve the structural strength of the paper after gluing.
