Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard processing technology, specifically to a corrugated cardboard heating and gluing device. Background Technology

[0002] Corrugated cardboard, with its numerous advantages such as light weight, high strength, low cost, and ease of processing, is widely used in the packaging industry. It's found in everything from everyday goods transport packaging to display packaging for various products. In the production process of corrugated cardboard, gluing is a crucial step, directly determining the structural stability and quality of the board. Only through proper gluing can the layers of the corrugated cardboard be tightly bonded, thus providing sufficient compression and impact resistance to meet the needs of different packaging scenarios. Therefore, developing efficient and reliable corrugated cardboard heating and gluing equipment is of great significance for improving the quality and efficiency of corrugated cardboard production.

[0003] The existing equipment has an inadequate ventilation system design, which cannot effectively remove the heat generated during the heating process. As the heating process progresses, the internal temperature of the equipment will continue to rise. If the heat cannot be dissipated in time, it will not only damage the internal components and shorten the service life of the equipment, but also affect the heating effect. Excessive temperature will cause the glue to cure prematurely, reducing the bonding strength. At the same time, improper ventilation will also cause poor air circulation inside the equipment, further aggravating the problem of uneven heating. Therefore, we need to propose a corrugated cardboard heating and gluing equipment. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 This utility model provides a technical solution:

[0027] A corrugated cardboard heating and gluing device, comprising:

[0028] Mounting shell 1, with two symmetrically distributed transparent plates 2 fixedly connected inside its side wall, a conveyor belt 3 inside the mounting shell 1, and multiple heating components 4 for heating the corrugated paper inside the mounting shell 1.

[0029] The upper end of the mounting shell 1 is fixedly connected to a plurality of evenly distributed branch pipes 5, and the upper end of each of the plurality of branch pipes 5 is fixedly connected to a main pipe 6. One end of the main pipe 6 is provided with a filter assembly 7 for filtering air.

[0030] The upper end of the mounting shell 1 is fixedly connected to the air collecting shell 9, the side wall of the air collecting shell 9 is fixedly connected to the fan 8, and the lower end of the air collecting shell 9 is provided with a plurality of evenly distributed air outlet holes 10.

[0031] For example, the mounting shell 1, as the main frame of the entire equipment, plays a crucial role in supporting and protecting the various internal components. The two transparent panels 2 not only allow operators to visually observe the transportation and heating of the corrugated cardboard inside the equipment, promptly identifying potential abnormalities such as cardboard jamming or uneven heating, but also do not affect the overall sealing and stability of the equipment. The conveyor belt 3, made of high-temperature and wear-resistant material, smoothly transports the corrugated cardboard to be heated and glued from one end of the equipment to the other, ensuring stable movement of the cardboard during heating. Multiple heating components 4 are evenly distributed in suitable positions inside the mounting shell 1 to ensure comprehensive and uniform heating of the corrugated cardboard, allowing the glue to fully melt and achieve a good bonding effect. Multiple branch pipes 5 are arranged in a regular pattern to draw air out of the mounting shell 1. The main pipe 6 collects the air drawn out from the branch pipes 5, allowing the air to flow centrally to subsequent processing stages. The filter component 7 effectively removes dust, impurities, and other contaminants from the air, preventing these contaminants from... During the internal circulation process, air adhering to the surface of corrugated cardboard or heating components affects the heating effect and cardboard quality. After filtration, the clean air is further processed and utilized by other components to ensure the cleanliness of the internal working environment. An air collecting shell 9 is fixedly connected to the upper end of the mounting shell 1. The air collecting shell 9 has a specific shape design that can effectively collect and guide air. A fan 8 is fixedly connected to the side wall of the air collecting shell 9. The fan 8 serves as the power source for the ventilation system and can generate a strong airflow. When the fan 8 is started, it will draw in the air inside the mounting shell 1 and distribute it through the air collecting shell 9. Multiple evenly distributed air outlets 10 are opened at the lower end of the air collecting shell 9. These air outlets 10 can evenly blow the air guided by the air collecting shell 9 to the upper end of the conveyor belt 3 to preheat the corrugated cardboard entering the mounting shell 1. On the one hand, ventilation can remove the heat generated during the heating process and prevent the internal temperature of the equipment from being too high and damaging the components. On the other hand, proper ventilation helps to maintain airflow, making the heating more uniform and improving the heating and bonding quality of the corrugated cardboard.

[0032] Each of the multiple heating components 4 includes an electric push rod 41, a lifting plate 42, and an electric heating plate 43;

[0033] The inner top of the mounting shell 1 is fixedly connected to a plurality of evenly distributed electric push rods 41. Each of the output ends of the plurality of electric push rods 41 is fixedly connected to a lifting plate 42. The lower ends of the plurality of lifting plates 42 are in contact with electric heating plates 43. The upper ends of the plurality of electric heating plates 43 are fixedly connected to a plurality of symmetrically distributed lifting frames 44. The plurality of lifting frames 44 are slidably connected to the plurality of lifting plates 42 respectively. The outer sides of the plurality of lifting frames 44 are all fitted with tension springs 45.

[0034] For example, the electric actuator 41 adopts a high-precision electric drive device, which can accurately control its extension length and movement speed. The lifting plate 42 is made of high-strength, high-temperature resistant material to ensure that it will not deform or be damaged when bearing the weight of the heating plate 43 and the heat generated during the heating process. The heating plate 43 is the core component of the heating assembly. It can convert electrical energy into heat energy to heat the corrugated cardboard below. Multiple lifting frames 44 are fixedly connected to the upper ends of multiple heating plates 43. The multiple lifting frames 44 are slidably connected to multiple lifting plates 42 respectively. This sliding connection method allows the heating plate 43 to maintain a stable movement trajectory during the lifting process, and can also buffer the pressure on the heating plate 43 to a certain extent. Tension springs 45 are sleeved on the outer side of multiple lifting frames 44. The tension springs 45 can provide a certain elasticity during the lifting process of the heating plate 43, so that the heating plate 43 and the lifting plate 42 maintain close contact, ensuring that the heat can be effectively transferred. They also play a role in buffering and shock absorption during the operation of the equipment, reducing wear between components and extending the service life of the equipment.

[0035] The filter assembly 7 includes a fixed housing 71, a sealing cap 72, and a collection frame 73;

[0036] The upper end of the mounting shell 1 is fixedly connected to a fixed shell 71, which is fixedly connected to the main pipe 6 and the fan 8 respectively. A sealing cover 72 is bolted to the upper end of the fixed shell 71, and a collection frame 73 is contacted at the lower end of the sealing cover 72. The collection frame 73 is slidably connected to the fixed shell 71. An entry hole is provided on the side wall of the collection frame 73. A limit rod 75 is fixedly connected inside the entry hole. Two symmetrically distributed elastic plates 74 are fixedly connected inside the entry hole, and the two elastic plates 74 are in contact with the limit rod 75 respectively.

[0037] For example, the fixed housing 71 is fixedly connected to the main pipe 6 and the fan 8 respectively, serving as a connection and support, making the entire filter assembly and other parts of the equipment form an organic whole. The sealing cover 72 is made of a material with good sealing performance and is tightly connected to the fixed housing 71 by bolting, which can effectively prevent air leakage and ensure the filtration effect. The lower end of the sealing cover 72 contacts the collection frame 73, which is slidably connected to the fixed housing 71. This sliding connection method facilitates the installation and removal of the collection frame 73. When it is necessary to clean the inside of the collection frame 73, it can be retracted. When collecting dust and impurities, simply open the sealing cover 72 and slide the collection frame 73 out of the fixed shell 71. The operation is convenient and quick. An entry hole is provided on the side wall of the collection frame 73. A limit rod 75 is fixedly connected inside the entry hole. Two symmetrically distributed elastic plates 74 are fixedly connected inside the entry hole. The two elastic plates 74 are in contact with the limit rod 75 respectively. The elastic plates 74 have a certain elasticity and can deform when air passes through. When the fan 8 is turned off, the elastic plates 74 return to their original position under their own elastic force, and the limit rod 75 limits the elastic plates 74.

[0038] Working principle: The corrugated cardboard to be heated and glued is placed at the starting end of the conveyor belt 3. The conveyor belt 3 starts to run under the action of the drive device, smoothly transporting the corrugated cardboard from one end of the equipment to the other end. During the transport process, the operator observes the transport and heating of the corrugated cardboard through the transparent plate 2. If problems such as cardboard jamming or uneven heating are found, the machine is stopped in time for adjustment.

[0039] According to the specifications of the corrugated cardboard and the gluing process requirements, the extension length and movement speed of the electric push rod 41 and the heating temperature of the electric heating plate 43 are set by the control system. When the start button of the heating component 4 is pressed, multiple electric push rods 41 start to work. Their output ends drive the lifting plate 42 to move downward. Since the lifting plate 42 is slidably connected to the lifting frame 44 at the upper end of the electric heating plate 43, and the outer side of the lifting frame 44 is fitted with a tension spring 45, the electric heating plate 43 also descends during the downward movement of the lifting plate 42. The tension spring 45 provides a certain elastic force to keep the electric heating plate 43 in close contact with the lifting plate 42, ensuring that the heat can be effectively transferred. When the electric heating plate 43 descends to the appropriate position, it starts to heat, converting electrical energy into heat energy to heat the corrugated cardboard below, so that the glue is fully melted and a good gluing effect is achieved.

[0040] The operator presses the start button of the blower 8, and the blower 8 starts to run, generating a strong airflow. The airflow draws the air inside the mounting shell 1 out through multiple branch pipes 5 and gathers into the main pipe 6, then flows into the filter assembly 7. In the filter assembly 7, the air enters from the inlet hole on the side wall of the collection frame 73. After the action of the elastic plate 74 and the limiting rod 75, the dust, impurities and other pollutants in the air are blocked in the collection frame 73, while the clean air continues to flow. The filtered air enters the air collecting shell 9. Under the guidance of the air collecting shell 9, it is evenly blown towards the upper end of the conveyor belt 3 through multiple evenly distributed air outlets 10, preheating the corrugated paper that is about to enter the mounting shell 1, while taking away some of the heat generated during the heating process, maintaining the airflow inside the equipment, and making the heating more uniform.

[0041] During equipment operation, the operator monitors the temperature of the heating plate 43 and the temperature inside the mounting shell 1 in real time through the temperature sensor. If the temperature is too high or too low, the operator adjusts the heating power of the heating plate 43 in a timely manner through the control system to ensure that the heating temperature is always kept within a suitable range and to ensure the heating and gluing quality of the corrugated cardboard.

[0042] Regularly check the accumulation of dust and impurities in the collection frame 73 of the filter assembly 7. When the dust and impurities in the collection frame 73 accumulate to a certain level, close the valve on the main pipe 6, open the sealing cover 72, slide the collection frame 73 out of the fixed shell 71, clean the dust and impurities inside, and then reinstall the collection frame 73 and the sealing cover 72 to ensure the filtration effect of the filter assembly 7. The two main pipes 6 can clean impurities without stopping the device.

[0043] In this application, the control method of the conveyor belt 3, electric push rod 41, electric heating plate 43, and fan 8 is automatic control by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, this application is mainly used to protect the structure, shape, and their combination, so this application will not explain the control method and circuit connection in detail. The device is powered by a built-in power supply or an external power supply.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
