Abstract
Description
Technical Field
[0001] This utility model relates to the field of rapid drying equipment technology, and in particular to a rapid drying equipment for paper tube processing. Background Technology
[0002] Paper tubes, as a common packaging material, are widely used in industries such as textiles, electronics, food, and printing. Paper tubes are lightweight, low-cost, and environmentally friendly, making them widely applicable in various packaging and support applications. The processing of paper tubes includes raw material preparation, rolling, drying, cutting, and gluing; the quality and performance of each step directly affect the quality of the paper tube.
[0003] During processing, paper tubes ultimately require a drying process to ensure sufficient stability and compressive strength. For example, Chinese Patent Publication No. CN220356009U provides an energy-saving corrugated paper production drying device. This device includes a drying chamber with a conveyor belt for transporting corrugated paper. Heating wires for drying the corrugated paper are installed on the inner top wall of the drying chamber. Heat-conducting components are installed on the inner walls of the drying chamber on both sides of the conveyor belt. The energy-saving corrugated paper production drying device of this invention activates the induced draft fan and exhaust fan on the curved tube. The induced draft fan draws the hot air accumulated at the top of the drying chamber into the curved tube, which is then exhausted by the exhaust fan. This prevents hot air from accumulating at the top of the drying chamber, which would otherwise lead to poor drying of the corrugated paper. Simultaneously, it improves the circulation of the internal hot airflow, further enhancing the drying effect of the corrugated paper.
[0004] Currently, during paper tube processing, the paper becomes damp during pretreatment and adhesive coating. If it is not dried after being formed into a paper tube, it is easy to cause deformation or instability of the adhesive parts. Most drying methods use a single hot air blower to blow hot air for drying. If the diameter or thickness of the paper tube is large, the single hot air drying method will increase the drying time and reduce work efficiency. In addition, most industrial paper tubes are long, and the paper tubes can only be dried in sections by partial drying. Therefore, it is necessary to design a paper tube drying equipment to meet the above problems and production needs. Utility Model Content
[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a rapid drying device for paper tube processing.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] Design a rapid drying device for paper tube processing, including an outer shell, which is a cylindrical structure. Two symmetrically distributed mounting rods are fixed at the lower end of the outer shell. Several tube seats are fixed on the inner wall of the outer shell by a bracket. The tube seats are arranged in a ring at equal intervals along the inner wall of the outer shell. An electric heating tube is inserted into the inside of the tube seat. The end of the electric heating tube away from the tube seat is fixed through the surface of the outer shell. The wiring end of the electric heating tube extends outward through the outer shell.
[0008] A duct is fixedly installed through the surface of the outer shell. An annular seat is provided at one end of the duct inside the outer shell. An annular cavity is opened inside the annular seat. The duct is fixedly installed through the annular seat. The end of the duct near the annular seat is connected to the inside of the annular cavity. Several nozzles are fixedly distributed on the side of the annular seat near the heating element. The nozzles are fixedly installed through the annular seat and are connected to the inside of the annular cavity. A hot air blower is fixedly installed at the upper end of the outer shell. The air outlet end of the hot air blower is connected to the flange at the end of the duct outside the outer shell.
[0009] The bottom of the outer shell has several air holes, which are rectangular holes.
[0010] In detail, both ends of the outer shell are fixed with caps, and the inside of the caps has a pipe delivery port that runs through them.
[0011] In detail, one end of the outer shell is fixed with threaded posts along both the upper and lower positions by brackets, and the surface of the cover is fixed with a collar corresponding to the position of the threaded posts by brackets. The surface of the threaded posts and the inside of the collar are slidably sleeved together.
[0012] In detail, the threaded column has a threaded cap at its end, and one end of the threaded cap is tightly fitted to the end face of the collar.
[0013] In detail, a cylinder is fixed through the bottom of the outer shell, and the cylinders are symmetrically distributed along both ends of the outer shell. The cylinders are equipped with piston rods for extension and retraction.
[0014] In detail, the two piston rods distributed at both ends are fixed with the same support plate. A bearing seat is fixedly installed on the top of the support plate by a bracket. The bearing seats are symmetrically distributed at both ends of the support plate.
[0015] In detail, the same shaft is rotatably installed between two adjacent symmetrically distributed shaft seats, and several guide rollers are arranged side by side and equidistantly distributed above the support plate. The guide rollers are fixedly sleeved with the corresponding shaft surfaces.
[0016] The design scheme proposed in this utility model has the following beneficial effects in application:
[0017] 1. This solution uses an annularly distributed electric heating tube with a temperature control switch to precisely control the heating temperature at 50-60℃, avoiding the paper tube from cracking due to high temperature. At the same time, the hot air blower delivers hot air into the outer shell through the annular cavity and nozzles, forming an airflow circulation with the bottom air holes, achieving uniform heating of the paper tube around the circumference, significantly improving drying efficiency. The dual drying modes of electric heating and hot air can be flexibly adjusted according to needs, ensuring both drying speed and effectively protecting the physical properties of the paper tube, suitable for processing paper tubes of different specifications.
[0018] 2. As described in 1, the equipment achieves quick disassembly and assembly of the cover through the cooperation of threaded column, collar and threaded cap, which is convenient for maintenance and adaptable to paper tubes of different diameters. The bottom cylinder can adjust the height of the guide roller. With the replacement pipe conveying port, it can flexibly adapt to the conveying and support needs of paper tubes of various sizes. The rolling design of the guide roller reduces the friction of paper tube conveying and reduces surface damage. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] Reference Figures 1-4A rapid drying device for paper tube processing includes a shell 1, which is a cylindrical structure. Two symmetrically distributed mounting rods 10 are fixed at the lower end of the shell 1. A base structure can be installed at the bottom of the mounting rods 10 for stable placement of the overall structure. Several tube seats 11 are fixed on the inner wall of the shell 1 by a bracket. The tube seats 11 are arranged in a ring at equal intervals along the inner wall of the shell 1. An electric heating tube 12 is inserted inside the tube seat 11. Several electric heating tubes 12 are connected in parallel to the same temperature control switch. The temperature control switch can ensure that the heating temperature of the electric heating tube 12 is controlled between 50 and 60 degrees Celsius to avoid excessive temperature and damage to the surface of the paper tube. The ring arrangement can achieve uniform drying of the paper tube throughout the drying process. The end of the electric heating tube 12 away from the tube seat 11 is fixed through the surface of the shell 1. The terminal of the electric heating tube 12 extends outward through the shell 1.
[0026] A duct 13 is fixedly installed through the surface of the outer shell 1. An annular seat 14 is provided at one end of the duct 13 inside the outer shell 1. An annular cavity 15 is opened inside the annular seat 14. The duct 13 and the annular seat 14 are fixedly installed through the duct. The end of the duct 13 near the annular seat 14 is connected to the inside of the annular cavity 15. Several nozzles 16 are fixedly distributed on the side of the annular seat 14 near the heating tube 12. The nozzles 16 are fixedly installed through the annular seat 14 and are connected to the inside of the annular cavity 15. A hot air blower 17 is fixedly installed at the upper end of the outer shell 1. The air outlet of the hot air blower 17 is connected to the flange at the end of the duct 13 outside the outer shell 1. When hot air drying is required, the power supply of the hot air blower 17 is turned on, so that the hot air blower 17 can deliver hot air into the duct 13, and then into the annular cavity 15 of the annular seat 14. Finally, hot air is delivered into the outer shell 1 through the nozzles 16. The effect of airflow is used to improve the overall drying efficiency of the paper tube.
[0027] The bottom of the outer shell 1 has several air holes 18. The air holes 18 have a rectangular hole structure. When hot air is transported inside the outer shell 1, the air holes 18 can exhaust air appropriately, ensure the air pressure balance inside the outer shell 1, improve the air flow effect, and improve the drying efficiency.
[0028] It should be further noted that both ends of the outer shell 1 are fixed with a cover 2. The inside of the cover 2 is provided with a pipe conveying port 21 that penetrates through it. The cover 2 and the pipe conveying port 21 are non-standard parts. The pipe conveying port 21 can be produced according to the actual pipe diameter and shape, so as to ensure that the paper tube can stably penetrate the cover 2 and enter the interior of the outer shell 1 when drying.
[0029] It should be further explained that threaded posts 22 are fixed to one end of the outer shell 1 along the upper and lower positions by brackets, and collars 23 corresponding to the positions of the threaded posts 22 are fixed to the surface of the cover 2 by brackets. The surface of the threaded posts 22 and the inside of the collars 23 are slidably sleeved. By cooperating with the threaded posts 22 and the collars 23, the quick positioning and docking of the cover 2 and the outer shell 1 can be avoided.
[0030] It should be further explained that the threaded end of the threaded post 22 is threaded with a threaded cap 24. One end of the threaded cap 24 is tightly fitted to the end face of the collar 23. When the cover 2 needs to be installed, the cover 2 is first covered to cover the port of the outer shell 1. At this time, the threaded post 22 and the collar 23 are fitted together to achieve quick positioning. Through the threaded connection between the threaded cap 24 and the threaded post 22, the cover 2 and the outer shell 1 can be stably installed.
[0031] It should be further explained that a cylinder 3 is fixed through the bottom of the outer shell 1. The cylinders 3 are symmetrically distributed along both ends of the outer shell 1. The cylinder 3 has a piston rod for extension and retraction inside. The extension and retraction of the piston rod of the cylinder 3 can realize the up and down movement of the guide roller 34, so as to adjust and support it according to the position of the paper tube.
[0032] It should be further noted that the two piston rods distributed at both ends are fixed with the same support plate 31. A bearing seat 32 is fixedly installed on the top of the support plate 31 by a bracket. The bearing seats 32 are symmetrically distributed at both ends of the support plate 31. The bearing seats 32 ensure the rotational stability of the shaft 33.
[0033] It should be further explained that the same shaft 33 is rotatably installed between two adjacent symmetrically distributed shaft seats 32. Several guide rollers 34 are arranged side by side and equidistantly distributed above the support plate 31. The guide rollers 34 are fixedly sleeved with the corresponding shafts 33. The guide rollers 34 can rotate based on the shafts 33, so that the paper tube can be rolled and conveyed when passing through the guide rollers 34.
[0034] Working principle: This solution uses multiple heating elements 12 arranged in a ring on the inner wall of the cylinder to uniformly heat the paper tube. The heating elements are inserted into the tube socket 11 and connected in parallel to a temperature control switch to ensure that the heating temperature is stable within a suitable range of 50~60℃. This temperature range can effectively evaporate the moisture inside the paper tube and avoid the paper tube surface from drying and cracking or deforming due to high temperature. The ring arrangement of the heating elements 12 allows heat to radiate evenly from all sides, solving the problem of uneven heating that is easily caused by unilateral heating.
[0035] The equipment uses a hot air blower 17 to drive a hot air circulation structure, which accelerates the drying of paper tubes. The hot air blower delivers high-temperature airflow through the air duct 13 to the annular cavity 15 of the annular seat 14, and then sprays it into the interior of the outer shell 1 through multiple nozzles 16. The hot air acts directly on the surface of the paper tube, promoting rapid evaporation of moisture. At the same time, the airflow carries away the humid air, forming a dynamic drying environment. The rectangular air hole 18 at the bottom of the outer shell 1 is designed to achieve air pressure balance and exhaust gas discharge, avoiding the accumulation of hot air and the resulting increase in humidity. This system is especially suitable for high humidity paper tubes or rapid drying needs. Through the dual effects of electric heating tube radiation heating and hot air convection, the drying time is significantly shortened and energy waste is reduced.
[0036] The conveying and positioning of the paper tubes rely on the coordinated adjustment of cylinder 3 and guide roller 34. The piston rod of the cylinder drives the support plate 31 to rise and fall, thereby adjusting the height of the guide roller to meet the support requirements of paper tubes of different diameters. The paper tubes pass through the pipe conveying port 21 of the cover 2 through the outer shell. The cover uses threaded post 22 and collar 23 for quick positioning and is locked by threaded cap 24 to ensure sealing. The guide roller rotates with shaft 33 to reduce frictional resistance when the paper tubes move and achieve smooth conveying. The detachable design of the cover at both ends facilitates the loading and unloading of paper tubes, and the customized conveying port 21 can match paper tubes of different specifications to prevent heat leakage. This mechanism not only ensures the continuity of the drying process, but also improves the versatility of the equipment.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
