Description

Technical Field

[0001] The invention relates to the technical field of carton production, and in particular to a corrugating machine for carton production. Background Art

[0002] In the carton production process, the manufacture of corrugated cardboard is a vital link. As the core equipment of the corrugated cardboard production line, the corrugator is responsible for processing single-sided paper and corrugated paper into corrugated cardboard with specific strength and structure. In this process, the coating mechanism applies glue to the corrugated paper so that it can be firmly combined with the single-sided paper later. However, the existing technology has obvious shortcomings. Usually, when the equipment is shut down and restarted, the staff needs to manually use a scraper and spend a lot of energy to remove the dried glue on the coating roller. Because the glue has strong adhesion after drying, this manual scraping method is not only cumbersome to operate, but also time-consuming and manpower-consuming, reducing production efficiency, and increasing operating costs for enterprises. There is an urgent need for a corrugated machine for carton production to solve the above problems. Summary of the invention

Description of the reference numerals in the drawings

[0018] For better explaining the present invention for easy understanding, the present invention will be described in detail below in conjunction with the drawings through specific implementation manners. Among them, the orientation nouns such as "upper", "lower", etc. mentioned in this article are based on Figure 1 the orientation shown.

[0019] The corrugating machine for carton production proposed in the embodiment of the present invention has a cleaning mechanism 300 detachably mounted on the frame 100 by a quick connection method. When it is necessary to clean the coating mechanism 200, the cleaning mechanism 300 is installed in place so that the scraping plate 320 is in close contact with the surface of the coating roller 210 of the coating mechanism 200. At this time, the aggregate hopper 310 is fixed to the frame 100 to ensure the overall stability of the cleaning mechanism 300 during the operation of the equipment; when the corrugating machine is running, the scraping plate 320 continuously scrapes off impurities such as dried glue attached to it as the coating roller 210 rotates, and the scraped materials slide down the scraping plate 320 into the aggregate hopper 310. When it is not necessary to clean the coating mechanism 200, the cleaning mechanism 300 can be quickly separated from the frame 100, improving work efficiency.

[0020] To better understand the above technical solutions, the exemplary embodiments of the present invention will be described in more detail below with reference to the drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and the scope of the present invention can be fully conveyed to those skilled in the art.

[0021] As shown Figures 1 to 8 in the figure, a corrugating machine for carton production according to an embodiment of the present application is used to combine a base paperboard and a base paper to form a corrugated board, and includes: a frame 100; a coating mechanism 200 disposed within the frame 100 for applying glue to the base paperboard; a cleaning mechanism 300 detachably mounted on the frame 100; wherein, the cleaning mechanism 300 includes a collecting hopper 310 and a scraping plate 320 connected to each other, and when the scraping plate 320 is in contact with the coating mechanism 200, the collecting hopper 310 is fixed to the frame 100.

[0022] The corrugating machine for carton production provided by the embodiment of the present application includes a frame 100, a coating mechanism 200, and a cleaning mechanism 300. Among them, both the coating mechanism 200 and the cleaning mechanism 300 are disposed within the frame 100. The frame 100 serves as the basic support structure of the entire device. The frame 100 provides a stable installation platform for other components, ensuring the stability and relative positional relationship of the coating mechanism 200, the cleaning mechanism 300, and their components during operation, and guaranteeing the normal operation of the entire corrugating machine and the coordinated work among various components; The coating mechanism 200 installed within the frame 100 mainly functions to apply glue to the base paperboard. The coating mechanism 200 accurately applies an appropriate amount of glue evenly on the base paperboard according to the production requirements of the corrugated board, laying a foundation for the subsequent production of high-quality corrugated board; The cleaning mechanism 300 is detachably mounted on the frame 100, which is convenient for installation and disassembly. The cleaning mechanism 300 is composed of a collecting hopper 310 and a scraping plate 320 connected to each other. When the scraping plate 320 is in contact with the coating mechanism 200, the collecting hopper 310 is fixed to the frame 100, so that when the device needs to clean the glue on the coating mechanism 200, the coating mechanism 200 can be directly cleaned; wherein, the scraping plate 320 is responsible for contacting the surface of the coating roller 210 within the coating mechanism 200. When cleaning the coating mechanism 200, it can timely scrape off the dried glue or other impurities attached to the surface of the coating roller 210, ensuring the cleanliness of the surface of the coating roller 210, and thus guaranteeing the coating quality. Its scraping effect is efficient and stable. The collecting hopper 310 is connected to the scraping plate 320. Its function is to collect the glue, impurities, etc. scraped off by the scraping plate 320. By being fixed to the frame 100, the collecting hopper 310 remains stable when collecting materials, avoiding the scattering of materials, and is also convenient for subsequent unified cleaning, further optimizing the production environment and operation process.

[0023] It can be seen from the above content that the cleaning mechanism 300 is detachably mounted on the frame 100 by means of a quick connection. When the coating mechanism 200 needs to be cleaned, the cleaning mechanism 300 is installed in place so that the scraper plate 320 is in close contact with the surface of the coating roller 210 of the coating mechanism 200. At this time, the collecting hopper 310 and the frame 100 are fixed to each other to ensure the overall stability of the cleaning mechanism 300 during the operation of the equipment. When cleaning is required, the corrugator is running, and the scraper plate 320 continuously scrapes off impurities such as dried glue attached to the coating roller 210 as it rotates, and the scraped material slides along the scraper plate 320 into the collecting hopper 310.

[0024] After the equipment is officially put into production, the operator only needs to start the corrugator according to the conventional production process. When it is necessary to clean the coating roller 210 on the coating mechanism 200, the cleaning mechanism 300 is installed on the frame 100. The cleaning mechanism 300 will automatically clean the coating roller 210 without manual intervention. The material collection situation in the collecting hopper 310 is regularly checked, and the materials are cleaned in time to ensure the normal operation of the cleaning mechanism 300. Manual cleaning of the coating roller requires specialized personnel to spend a lot of time and energy to operate tools such as shovels for cleaning, which is labor-intensive and inefficient. The cleaning mechanism 300 of the present invention reduces manual intervention and reduces dependence on manual cleaning, allowing enterprises to reduce corresponding manpower investment. For example, each production line originally needed to be equipped with 1 to 2 workers who were specifically responsible for cleaning the coating roller. After using this device, this part of the staffing can be reduced, thereby reducing labor costs.

[0025] like Figures 1 to 4 As shown, in some examples, the corrugator for carton production further includes: a mounting frame 400, symmetrically fixedly mounted on the inner wall of the frame 100, the mounting frame 400 is close to one end of the coating mechanism 200, and is formed with a groove 401 whose opening direction is away from the coating mechanism 200, and the collecting hopper 310 is clamped on the side of the mounting frame 400 away from the groove 401; In this technical solution, the mounting frame 400 is symmetrically fixed on the inner wall of the frame 100, and a groove 401 is formed at one end thereof close to the coating mechanism 200, with the opening direction facing away from the coating mechanism 200, wherein the groove 401 has the functions of positioning and supporting. The two symmetrically arranged mounting frames 400 provide precise positioning and reliable support for the cleaning mechanism 300. By fixing it on the inner wall of the frame 100, the entire cleaning mechanism 300 can be firmly installed in a suitable position of the corrugator, ensuring the accuracy of the relative position with the coating mechanism 200.

[0026] The aggregate hopper 310 is snap - connected to the side of the mounting frame 400 away from the groove 401. This snap - connection method is not only convenient for installation but also can effectively fix the position of the aggregate hopper 310 during the operation of the equipment, preventing it from shifting due to vibrations or other reasons, ensuring the stability of the aggregate hopper 310 when collecting the scraped glue and impurities. The snap - connection method can be selected such that a snap - connection groove is formed at the bottom of the aggregate hopper 310, and during snap - connection, the snap - connection groove is snap - connected to the mounting frame 400.

[0027] The above - mentioned cleaning mechanism 300 further includes: a support rod 330, one end of which is hinged to the above - mentioned scraping plate 320; a mounting assembly 340, detachably installed in the above - mentioned groove 401, the other end of the above - mentioned support rod 330 is rotatably connected to the above - mentioned mounting assembly 340; a first elastic member 350, one end of which is connected to the above - mentioned mounting assembly 340, and the other end is connected to the above - mentioned aggregate hopper 310; a second elastic member 360, one end of which is connected to the above - mentioned mounting assembly 340, and the other end is connected to the above - mentioned scraping plate 320, for making the above - mentioned scraping plate 320 in close contact with the above - mentioned coating mechanism 200.

[0028] In this technical solution, the cleaning mechanism 300 further includes a support rod 330, a mounting assembly 340, a first elastic member 350 and a second elastic member 360. Among them, one end of the support rod 330 is hinged to the scraping plate 320, and the other end is rotatably connected to the mounting assembly 340. The function of the support rod 330 is an articulated joint. The mounting assembly 340 is detachably installed in the groove 401, and it plays a key role in connecting each component. By being installed in the groove 401, it connects each part of the cleaning mechanism 300 with the mounting frame 400 into a whole. In addition, its connection with the support rod 330, the first elastic member 350 and the second elastic member 360 provides a stable working structure for the entire cleaning mechanism.

[0029] One end of the first elastic member 350 is connected to the mounting assembly 340, and the other end is connected to the aggregate hopper 310. The first elastic member 350 has an elastic restoring force. Its function is to fasten the aggregate hopper 310 so that, on the basis of snap - connection, it can be more tightly fixed to the mounting frame 400 through elastic tension. During the operation of the equipment, when vibrations or other situations occur, the first elastic member 350 can play a buffering and stabilizing role, preventing the aggregate hopper 310 from loosening and ensuring that the aggregate hopper 310 can continuously and stably collect materials.

[0030] One end of the second elastic member 360 is connected to the mounting assembly 340, and the other end is connected to the scraping plate 320. The main function of the second elastic member 360 is to make the scraping plate 320 in close contact with the coating mechanism 200. Due to its elasticity, during the operation of the equipment, it can automatically adjust the position and pressure of the scraping plate 320 according to the unevenness of the surface of the coating roller 210 or the vibration of the coating mechanism 200, etc., and always ensure that there is an appropriate contact pressure between the scraping plate 320 and the coating roller 210. In this way, it can effectively scrape off the dried glue on the surface of the coating roller 210, and will not excessively wear the coating roller 210 or affect the normal progress of the coating work due to excessive pressure.

[0031] During the installation of the cleaning mechanism 300, first, it is clamped in the groove 401 through the mounting assembly 340. At this time, the aggregate hopper 310 is rotated relative to the scraping plate 320 so that the aggregate hopper 310 is clamped on the mounting frame 400. At this time, under the combined action of the first elastic member 350 and the second elastic member 360, the scraping plate 320 is in close contact with the coating roller 210 in the coating mechanism 200. At the same time, the scraping plate 320 is inclined relative to the top opening of the aggregate hopper 310 at this time, which is convenient for the material scraped by the scraping plate 320 to enter the aggregate hopper 310 along the inclined scraping plate 320; when it is necessary to remove the cleaning mechanism 300, the aggregate hopper 310 can be directly manually lifted to separate the aggregate hopper 310 from the mounting frame 400. At the same time, during this process, the scraping plate 320 rotates relative to the aggregate hopper 310. At this time, under the combined action of the first elastic member 350 and the second second elastic member 360, the mounting assembly 340 can be separated from the groove 401, and thus the scraping plate 320 can be separated from the coating mechanism 200.

[0032] Through one operation, when the scraping plate 320 is in contact with the coating mechanism 200, the cleaning mechanism 300 is installed on the frame 100, achieving the effects of quick installation and quick disassembly, and improving work efficiency.

[0033] As Figures 2 to 4 shown, in some examples, the above-mentioned mounting assembly 340 includes: a connecting rod 341, and one end of the above-mentioned support rod 330 away from the above-mentioned scraping plate 320 is rotatably installed on the connecting rod 341; a rectangular limit block 342, fixedly installed at both ends of the above-mentioned connecting rod 341, the above-mentioned rectangular limit block 342 is adapted to the above-mentioned groove 401, and the above-mentioned rectangular limit block 342 is detachably installed in the above-mentioned groove 401; a rotating cam 343, coaxially rotatably installed on the connecting rod 341, and the first elastic member 350 and the second elastic member 360 are respectively arranged at both ends of the rotating cam 343.

[0034] In this technical solution, the end of the support rod 330 away from the scraper plate 320 is rotatably mounted on the connecting rod 341, thereby establishing a flexible rotation relationship between the scraper plate 320, the support rod 330 and the connecting rod 341. This allows the scraper plate 320 to be rotatably adjusted with the connecting rod 341 as the axis through the support rod 330. In the actual working process, since there may be a certain shape error on the surface of the coating roller 210 or a slight shake during operation, the scraper plate 320 can be flexibly rotated around the connecting rod 341 with the help of the support rod 330, and always maintain a good contact state with the coating roller 210, so as to more effectively scrape off impurities such as dried glue on the surface of the coating roller 210 and ensure the cleaning effect.

[0035] The rectangular limit block 342 is fixedly installed at both ends of the connecting rod 341, and it is adapted to the groove 401 and can be detachably installed in the groove 401, thereby ensuring the accuracy and stability of the installation of the installation component 340 in the groove 401. When the cleaning mechanism 300 needs to be installed, the rectangular limit block 342 can be accurately inserted into the groove 401 to limit the position of the connecting rod 341 on the frame 100; the rectangular limit block 342 is stuck in the groove 401, which can ensure the overall stability of the installation component 340, thereby ensuring that the scraper plate 320, the collecting hopper 310 and other components will not be affected by the instability of the installation component 340. The coordinated work with the coating mechanism 200, so that the cleaning mechanism 300 can always operate stably and reliably, ensuring its function of cleaning the coating roller 210 in the equipment is realized normally.

[0036] By respectively arranging the first elastic member 350 and the second elastic member 360 at the two ends of the rotating cam 343, it can be achieved that when the scraping mechanism 300 is removed from the mounting frame 400, the first elastic member 350 and the second elastic member 360 can rotate along with the rotating cam 343, and the acting force between the first elastic member 350 and the second elastic member 360 can be adjusted to ensure stable folding movement between the scraper plate 320 and the collecting hopper 310 to avoid interference.

[0037] To sum up, the connecting rod 341, the rectangular limit block 342 and the rotating cam 343 in the mounting assembly 340 effectively realize the positioning, connection and stable operation of the cleaning mechanism 300 in the groove 401 through the above functions and mutual cooperation, which plays an important role in the normal operation of the adjustable corrugating machine and the cleaning effect of the coating roller 210.

[0038] like Figures 1 to 5 and Figure 8As shown, in some examples, the above-mentioned cleaning mechanism 300 further includes: an arc-shaped slide rail 301 formed on the inner wall of the above-mentioned aggregate hopper 310, and one end of the above-mentioned scraping plate 320 is slidably installed in the above-mentioned arc-shaped rail 301; an arc-shaped baffle 370 arranged along the edge of the above-mentioned arc-shaped slide rail 301 on the inner wall of the above-mentioned aggregate hopper 310, for forming a receiving space 302 with an open top in the above-mentioned aggregate hopper 310, and the above-mentioned arc-shaped slide rail 301 is arranged outside the above-mentioned receiving space 302.

[0039] In this technical solution, the arc-shaped slide rail 301 is formed on the inner wall of the aggregate hopper 310, and one end of the scraping plate 320 is slidably installed in the arc-shaped rail 301. On the one hand, when the scraping plate 320 rotates around the hinge point with the support rod 330, its end inside the aggregate hopper 310 can slide along the arc-shaped slide rail 301, restricting the movement range of the scraping plate 320 so that it can only move within a suitable angle range, preventing the scraping plate 320 from shaking excessively or shifting in position, ensuring that it always maintains good contact with the coating roller 210, and thus stably realizing the cleaning function of the coating roller 210. On the other hand, the arc-shaped slide rail 301 plays a role in supporting the scraping plate 320, sharing part of the pressure received by the scraping plate 320 during the working process, improving the stability and working reliability of the scraping plate 320, and extending its service life.

[0040] The arc-shaped baffle 370 is arranged along the edge of the arc-shaped slide rail 301 on the inner wall of the aggregate hopper 310. Its main function is to jointly form a receiving space 302 with an open top with other parts of the aggregate hopper 310. The structure of the open top is to facilitate the collection of materials such as glue and impurities scraped off by the scraping plate 320. During the working process of the corrugating machine, these materials slide down along the scraping plate 320 and can directly fall into the receiving space 302, avoiding the scattering of materials everywhere and being beneficial to maintaining a clean production environment.

[0041] The arc-shaped baffle 370 also plays an auxiliary positioning and protection role in the sliding of the scraping plate 320 on the arc-shaped slide rail 301. It is arranged along the edge of the arc-shaped slide rail 301, which can prevent the scraping plate 320 from slipping out of the arc-shaped slide rail 301 during the sliding process, ensuring that the scraping plate 320 slides stably on the specified path. At the same time, as a part of the inner wall structure of the aggregate hopper 310, the arc-shaped baffle 370 cooperates with the arc-shaped slide rail 301 to enhance the stability of the entire structure, ensuring the stability and reliability of the cleaning mechanism 300 during long-term operation.

[0042] The arc-shaped slide rail 301 is arranged outside the storage space 302, so that the sliding mechanism of the scraping plate 320 is separated from the space for collecting materials, avoiding the interference of the materials in the storage space 302 during the sliding process of the scraping plate 320, ensuring that the scraping plate 320 can always slide smoothly on a stable track; at the same time, it can prevent materials from accumulating on the arc-shaped slide rail 301 and affecting its normal operation, ensuring that each component of the cleaning mechanism 300 can perform its own functions effectively.

[0043] In some examples, when the scraping plate 320 is in contact with the coating mechanism 200, the scraping plate 320 is clamped with the aggregate hopper 310.

[0044] In this technical solution, the scraping plate 320 is clamped with the aggregate hopper 310, ensuring that during the cleaning process, materials such as glue and impurities scraped from the surface of the coating mechanism 200 can be smoothly transported from the scraping plate 320 to the aggregate hopper 310. Due to their firmly clamped connection, the materials can naturally slide along the surface of the scraping plate 320 into the aggregate hopper 310 after being scraped off, avoiding the spilling of materials midway, ensuring the effectiveness and continuity of material collection during the cleaning process, and keeping the production environment relatively clean.

[0045] During the operation of the equipment, the scraping plate 320 will be affected by the frictional force and vibration brought by the rotation of the coating roller 210. If the connection between the scraping plate 320 and the aggregate hopper 310 is unstable, it may cause the position of the scraping plate 320 to change, thus affecting its contact with the coating roller 210 and reducing the cleaning effect. The clamping method ensures the position fixity of the scraping plate 320 during the working process, enabling the cleaning mechanism 300 to better cope with various external force effects generated by the operation of the coating mechanism 200 and ensuring the continuous and stable operation of the entire cleaning mechanism.

[0046] When in contact with the coating roller 210 and in the working state, the scraping plate 320 can ensure that it always maintains an appropriate scraping angle and force through the clamping with the aggregate hopper 310. Once this clamping relationship is damaged, the working state of the scraping plate 320 may change, such as uneven scraping force or incomplete coverage of the area to be cleaned, affecting the cleaning quality of the coating mechanism. Therefore, a stable clamping structure is an important factor to ensure the reliable operation of the cleaning mechanism.

[0047] As Figures 2 to 5 and Figure 8 shown, in some examples, the cleaning mechanism 300 further includes: arc-shaped scrapers 380, which are arranged on the scraping plate 320 in an overlapping and equidistant manner for inclined contact with the coating mechanism 200.

[0048] In this technical solution, the inclined arc-shaped scraper 380 and the scraping plate 320 form an inclined angle. The arc-shaped scraper 380 can clean the coating mechanism 200 from an inclined angle. The overlapping and equidistant arrangement ensures that the entire cleaning area can be evenly cleaned within the lateral range, avoiding the occurrence of cleaning dead spots or uneven cleaning intensity.

[0049] The arc-shaped scraper 380 is beneficial to dispersing the pressure on the scraping plate 320 and the coating mechanism 200 during the scraping process. Compared with an ordinary flat scraper, when the arc-shaped scraper 380 contacts the surface of the coating mechanism, its arc-shaped structure can distribute the pressure more evenly, avoiding damage to the surface of the coating roller 210 caused by excessive local pressure, and at the same time reducing the wear of the scraping plate 320 itself. For example, during long-term cleaning work, a flat scraper may leave scratches on the surface of the coating roller 210 due to local pressure concentration, or wear the contact part of the scraping plate 320 itself more quickly. However, through the pressure dispersion effect, the arc-shaped scraper 380 extends the service life of the scraping plate 320 and the coating mechanism 200.

[0050] The arc-shaped scraper 380 is arranged on the scraping plate 320 in an inclined and equidistant manner and is in inclined contact with the coating mechanism 200, improving the cleaning function of the cleaning mechanism 300. It works in cooperation with the scraping plate 320 to further enhance the cleaning effect, efficiency and reliability of the cleaning mechanism.

[0051] As Figures 1 to 5 shown, in some examples, the above-mentioned coating mechanism 200 includes: a coating roller 210 rotatably installed within the above-mentioned frame 100; a warming component 220 provided within the above-mentioned coating roller 210 for heating the above-mentioned coating roller 210; a glue delivery rack component 230 provided within the above-mentioned frame 100. A plurality of glue outlet holes 201 are formed at equal intervals at the top of the glue delivery rack component 230. The plurality of above-mentioned glue outlet holes 201 are arranged at equal intervals along the axis of the above-mentioned coating roller 210 for applying glue to the outer wall surface of the above-mentioned coating roller 210.

[0052] In this technical solution, the coating roller 210 is rotatably installed within the frame 100, and the warming component 220 is provided on the inner wall of the coating roller 210. Its main function is to heat the outer wall of the coating roller 210. By heating the outer wall of the coating roller 210, the glue coated on the roller surface can be maintained at an appropriate temperature, improving the fluidity and viscosity of the glue. At an appropriate temperature, the glue can better adhere to the surface of the coating roller 210 and can be more evenly transferred when contacting materials such as corrugated cardboard, thereby improving the gluing quality and enhancing the bonding effect between the papers. For example, for some temperature-sensitive glues, an appropriate heating temperature can prevent the glue from drying too quickly or having insufficient viscosity, ensuring the bonding strength and quality of the corrugated cardboard.

[0053] The glue delivery frame assembly 230 is arranged within the frame 100, providing a channel and a distribution structure for glue supply in the gluing operation. A plurality of glue outlet holes 201 are formed equidistantly at its top. The equidistantly arranged glue outlet holes 201 can make the glue evenly distributed in the circumferential direction of the coating roller 210. When the coating roller 210 rotates, the glue flowing out from the glue outlet holes 201 will evenly adhere to the outer wall surface of the coating roller 210, achieving a comprehensive and uniform gluing effect on the outer wall surface of the coating roller 210. This uniform gluing is crucial for ensuring the even distribution of glue on the corrugated board, helping to improve the gluing quality of the corrugated board, avoiding situations of excessive or insufficient glue in local areas, and reducing product quality problems caused by uneven gluing, such as weak local adhesion or cardboard deformation.

[0054] The coating roller 210, the warming component 220, and the glue delivery frame assembly 230 together constitute the coating mechanism 200. They cooperate closely with each other, enabling the gluing process of the corrugator to be completed efficiently and precisely. The rotational movement of the coating roller 210 provides the power and carrier for coating the glue. The warming component 220 improves the performance of the glue by heating the coating roller 210. The glue delivery frame assembly 230 precisely controls the output and distribution of the glue. This collaborative work ensures that the coating roller 210 can provide a uniform and high-quality glue coating to the corrugated board, which plays a key role in improving the production efficiency and product quality of the corrugator and is an important part to ensure the stable and reliable operation of the entire corrugator.

[0055] The above-mentioned warming component 220 includes: a heating medium 221 arranged within the above-mentioned coating roller 210; a heating rod 222 arranged within the above-mentioned coating roller 210 for heating the above-mentioned heating medium 221.

[0056] In this technical solution, the heating medium 221 is arranged within the coating roller 210. Exemplarily, the heating medium 221 can be selected but is not limited to glycerol. Glycerol has good thermal conductivity and specific heat capacity characteristics. As a heat medium, it plays an important role in storing and transferring heat in the warming component 220. The heating medium 221 is filled inside the coating roller 210, capable of absorbing the heat generated by the heating rod 222 and evenly diffusing it to the entire inner wall of the coating roller 210, thereby making the outer wall of the coating roller 210 receive heat more evenly. This uniform heat transfer ensures that the surface temperature of the coating roller 210 is consistent, effectively avoiding the phenomenon of uneven gluing caused by local temperature differences. For example, without the heating medium 221, the temperature in the area near the heating rod 222 may be too high, while the temperature in the area far from the heating rod 222 is relatively low, which will affect the distribution and performance of the glue on the surface of the coating roller 210.

[0057] The heating rod 222 is disposed inside the coating roller 210. Its main function is to heat the heating medium 221, generating heat through electrification. The heating rod 222 converts electrical energy into heat energy and transfers it to the surrounding heating medium 221. This heating process can precisely control the temperature to ensure that the heating medium 221 reaches and maintains an appropriate temperature range, so that the outer wall of the coating roller 210 can continuously maintain an ideal temperature for improving the performance of the glue. During actual operation, the heating power and working time of the heating rod 222 can be reasonably adjusted according to the characteristics of the glue used and the requirements of the production process to achieve precise control of the temperature of the coating roller 210.

[0058] The heating medium 221 and the heating rod 222 work together to jointly ensure that the warming component 220 can effectively heat the outer wall of the coating roller 210. The heating rod 222, as the source of heat generation, continuously provides heat. The heating medium 221, as the carrier and spreader of heat, evenly distributes the heat generated by the heating rod throughout the entire interior of the coating roller 210 and then transfers it to the outer wall of the coating roller 210. This cooperative relationship ensures that the coating roller 210 can work externally at a stable and uniform temperature, enabling the glue to have good fluidity and viscosity characteristics on the surface of the coating roller 210, which helps the glue to evenly adhere to materials such as corrugated cardboard during subsequent coating processes, greatly improving the quality and effect of glue application, and ensuring the bonding quality and stability of products during the production process of the corrugating machine.

[0059] In summary, through the coordinated cooperation of the heating medium 221 and the heating rod 222, the warming component 220 provides a stable and uniform heating environment for the coating roller 210, playing an important supporting role in the glue application operation and overall production quality of the corrugating machine.

[0060] As Figure 1 、 Figure 2 、 Figure 6 and Figure 7 shown, in some examples, the corrugating machine for carton production further includes: a preheating component 500, which is disposed behind the above-mentioned coating mechanism 200 along the advancing direction of the original cardboard and is used to preheat the original cardboard. The above-mentioned preheating component 500 includes: a preheating frame 510, which is disposed inside the above-mentioned frame 100 and forms a preheating space 501 for the original cardboard to pass through; a plurality of preheating holes 520, which are communicated with an external heating device and are disposed inside the above-mentioned preheating space 501. A plurality of the above-mentioned preheating holes 520 are symmetrically and equidistantly disposed on the upper and lower sides of the original cardboard along the moving direction of the original cardboard and are used to blow hot air onto the original cardboard.

[0061] In this technical solution, the preheating component 500 is arranged behind the coating mechanism 200 along the forward direction of the original cardboard. After the original cardboard has completed the gluing process through the coating mechanism 200, it needs to be preheated before the subsequent processes such as corrugated forming. This is because appropriate preheating can improve the physical properties of the original cardboard, making it easier to form and better combine with glue, thereby improving the processing quality and product stability in the entire carton production process.

[0062] The preheating frame 510 is arranged in the frame 100, and a preheating space 501 is formed inside the frame 100 for the raw paperboard to pass through. The raw paperboard moves in this space to receive preheating treatment, which helps to confine the raw paperboard in a specific preheating environment, improve the efficiency of heat transfer, avoid excessive heat loss to the surrounding environment, and ensure the consistency and controllability of the preheating effect of the raw paperboard. If the preheating holes 520 are connected to an external heating device, it is ensured that the preheating holes 520 have a continuous supply of hot air. These preheating holes 520 are symmetrically and equidistantly arranged in the preheating space 501 along the moving direction of the original paperboard, and are located on the upper and lower sides of the original paperboard, so that during the movement of the original paperboard, various parts in the width direction of the original paperboard can evenly receive the blowing of hot air. If the preheating holes 520 are unevenly arranged, the original paperboard may be locally overheated or insufficiently heated. Overheating may cause damage to the paperboard material, affecting its strength and durability; insufficient heating cannot achieve the expected preheating effect and cannot well improve the processing performance of the paperboard. For example, when the original paperboard passes through the preheating space 501 at a uniform speed, the symmetrical and equidistant preheating holes can ensure that at the same time, various parts in the width direction of the original paperboard obtain heat transfer of the same intensity and duration, so that the entire original paperboard can be fully and evenly preheated, providing good conditions for subsequent production processes.

[0063] When the corrugator is running, the external heating device blows hot air into the preheating space 501 through the connected preheating holes 520. After the hot air is ejected from the preheating holes 520, it directly acts on the raw paperboard passing through the preheating space 501. The heat of the hot air is transferred to the raw paperboard, so that its temperature rises to the expected preheating temperature. The preheated raw paperboard changes in physical properties, such as its flexibility is enhanced and its fiber structure is more relaxed. This can make the raw paperboard easier to bend and form in the subsequent corrugated forming process, reducing the risk of rupture caused by excessive stretching or folding; at the same time, the increase in temperature can also make the raw paperboard and the glue applied after the coating process interact better, enhance the bonding force between the two, improve the overall bonding quality of the corrugated paperboard, and ultimately improve the production quality and product performance of the carton.
