Description

Technical Field

[0001] This application relates to the field of paperboard production technology, and in particular to a heating mechanism for the flute tip of corrugated paperboard. Background Technology

[0002] Corrugated cardboard is a composite material composed of corrugated paper and face paper. The corrugated cardboard tip instant heating device is a piece of equipment used in the corrugated cardboard production process. Its function is to soften the tip part of the corrugated cardboard by heating it instantly, so as to facilitate the lamination of the upper, middle and lower layers of cardboard.

[0003] Furthermore, existing patent publication number CN221678193U discloses an instantaneous heating device for the corrugated cardboard tip. This device addresses the problem of inconvenient steam box position adjustment in existing instantaneous heating devices. However, it does not consider that the high-temperature steam will dissipate to the surroundings when it exits the steam box, potentially leading to uneven heating of the cardboard. Moreover, this high-temperature steam can be reused. Therefore, this solution proposes a corrugated cardboard tip heating mechanism. Utility Model Content

[0004] To address the issue of high-temperature steam escaping into the surroundings, this application provides a corrugated cardboard tip heating mechanism.

[0005] The corrugated cardboard tip heating mechanism provided in this application adopts the following technical solution:

[0006] A corrugated cardboard tip heating mechanism includes a mounting frame. A steam assembly is provided at one end of the mounting frame. The steam assembly includes a steam box connected to the mounting frame. Air ducts with inwardly inclined tops are symmetrically fixed on both sides of the steam box. Multiple inwardly inclined exhaust ports are equidistantly fixed on the top surface of the air ducts. A fan is symmetrically fixed at the bottom end of the steam box. A vertically upward connecting pipe is fixedly connected to the input end of the fan. A collection port for collecting high-temperature steam is fixedly installed at one end of the connecting pipe.

[0007] By adopting the above technical solution, the steam assembly at one end of the mounting frame can discharge steam in a direction through the air ducts and exhaust ports on both sides of the steam box to heat the target. At the same time, the fan at the bottom collects high-temperature steam through the connecting pipe and collection port, realizing the recycling of steam. This not only provides heating function but also saves energy to a certain extent and improves the utilization rate of heat.

[0008] Preferably, the top surface of the steam box is provided with equidistant vent holes for the discharge of high-temperature steam.

[0009] By adopting the above technical solution, the equidistant vents on the top surface of the steam box allow the high-temperature steam inside the box to be discharged in an orderly manner. Through the reasonable distribution of vents, the steam can act on the cardboard surface more evenly, thereby heating or treating the object and ensuring the effectiveness and efficiency of the steam.

[0010] Preferably, the output end of the fan is fixedly connected to the bottom middle of the air duct via a pipe.

[0011] By adopting the above technical solution, the fan output end and the bottom of the duct are fixedly connected by a pipe, which allows the fan to transport the collected gas to the duct through the pipe and then discharge it through the exhaust port on the duct, realizing the directional transmission and distribution of the gas and ensuring that the gas can be discharged evenly from the duct to heat the target area.

[0012] Preferably, one end of the mounting bracket is fixedly connected to a positioning plate that is movably connected to both ends of the steam box, and the positioning plate has an arc-shaped hole in a ring.

[0013] By adopting the above technical solution, one end of the mounting bracket is movably connected to both ends of the steam box through a positioning plate, and an arc-shaped hole is opened around the positioning plate, so that the steam box can be rotated and its position adjusted at a certain angle by relying on the arc-shaped hole. This enhances the flexibility of the steam box installation and makes it easier to optimize the angle and position of the steam box according to actual usage needs, so as to better perform its heating and other functions.

[0014] Preferably, a positioning bolt with one end fixedly connected to the steam box is inserted through the arc-shaped hole.

[0015] By adopting the above technical solution, the positioning bolts can be moved through the arc-shaped holes on the positioning plate and fixedly connected to the steam box. After the steam box is adjusted in angle and position based on the arc-shaped holes, it can be fixed in a suitable position to ensure the stability of the steam box during operation and ensure its normal function.

[0016] Preferably, heating components are provided on both sides of the mounting frame. The heating components include positioning blocks that are fixedly connected to one side of the mounting frame. The positioning blocks vertically move through the limit plate, and the outer side of the positioning blocks are symmetrically threaded with limit bolts for fixing the limit plate.

[0017] By adopting the above technical solution, in the heating components on both sides of the mounting frame, the positioning block is fixedly connected to the mounting frame, and the limiting plate moves vertically through the positioning block. The limiting plate can be fixed on the positioning block by the limiting bolt. This design can flexibly adjust the position of the limiting plate and fix it, which is convenient for positioning the relevant parts of the heating component according to actual needs.

[0018] Preferably, both ends of the limiting plate are fixedly connected to support frames, and the middle of each support frame is fixedly connected to a fixing plate, with a heating plate fixedly installed on each of the two fixing plates.

[0019] By adopting the above technical solution, the support frames at both ends of the limiting plate and the positioning plate in the middle are used to fix the heating plate. The limiting plate can be adjusted and fixed in position by positioning blocks and limiting bolts. This allows the heating plate to flexibly change position and be stably set according to actual needs, so as to better heat the target area.

[0020] Preferably, one end of each of the two support frames is fixedly perforated with a limiting rod for limiting.

[0021] By adopting the above technical solution, the limiting rods fixed through one end of the two support frames can limit the relevant components, ensuring that the support frames and the heating plates installed on them maintain a stable position and state during operation, and avoiding unnecessary displacement or shaking.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The top of the steam box's duct is designed with an inwardly sloping surface, and multiple inwardly sloping exhaust ports are installed at equal intervals. This unique structure allows steam to be ejected from the exhaust ports at a specific angle, precisely targeting the corrugated tip of the cardboard. This reduces unnecessary steam loss to the surrounding areas, and the concentrated steam injection onto the areas that need heating not only improves steam utilization but also ensures uniform heating of the cardboard in critical areas. This effectively avoids uneven heating caused by steam loss and improves the processing quality of the cardboard.

[0024] 2. The steam box can be rotated within a certain range around the positioning bolt through the arc-shaped hole and positioning bolt. By adjusting the angle of the steam box, the direction of steam injection can be precisely controlled. This allows for flexible adjustment of the steam injection range and angle according to different specifications and heating requirements of cardboard, ensuring that all parts of the middle layer of the cardboard are fully and evenly heated.

[0034] The following is in conjunction with the appendix Figure 1 - Figure 6 This application will be described in further detail.

[0035] The device's "up, down, left, right" perspectives are... Figure 1 The orientation of the attached diagram is the reference.

[0036] This application discloses a corrugated cardboard tip heating mechanism.

[0037] Reference Figure 1 - Figure 3 As shown, a corrugated cardboard tip heating mechanism includes a mounting frame 1. A steam assembly 3 is provided at one end of the mounting frame 1. The steam assembly 3 includes a steam box 301 connected to the mounting frame 1. Air ducts 302 are symmetrically fixedly connected to both sides of the steam box 301. The top of the air ducts 302 is inclined inward. Multiple exhaust ports 303 are equidistantly fixedly installed on the top surface of the air ducts 302. The multiple exhaust ports 303 are all distributed in an inward inclined manner. Fans 304 with a width smaller than the width of the steam box 301 are symmetrically fixedly installed at both ends of the bottom of the steam box 301. A connecting pipe 305 is fixedly connected to the input end of the fan 304. The connecting pipe 305 is perpendicular to the top at a right angle. A collection port 306 is fixedly installed at one end of the connecting pipe 305. The collection port 306 is rectangular and is used to collect high-temperature steam.

[0038] Mounting frame 1 provides support and installation foundation for the overall structure. Steam box 301 serves as the steam carrier and supply source, generating high-temperature steam. After the fan 304 starts, it collects the high-temperature steam through connecting pipe 305 and rectangular collection port 306. The collected steam enters steam box 301 and flows to air ducts 302 symmetrically arranged on both sides. Since the top of air duct 302 is an inwardly inclined slope, and multiple inwardly inclined exhaust ports 303 are installed at equal intervals on its top surface, steam will be ejected from these exhaust ports 303 at a specific angle, precisely heating the tip of the corrugated cardboard and meeting the heating requirements in the corrugated cardboard processing process.

[0039] It should be noted that the steam box 301 is connected to a steam device that can generate high-temperature steam through a pipe. The steam device and the blower 304 are existing technologies and will not be described here.

[0040] Reference Figure 3 - Figure 6 As shown, the top surface of the steam box 301 has air vents arranged at equal intervals. The output ends of the two fans 304 are connected to the bottom center of the air duct 302 via pipes. One end of the mounting bracket 1 is fixedly connected to a positioning plate 101, which is movably connected to both ends of the steam box 301. The positioning plate 101 has an arc-shaped hole 102 for limiting the position, and a positioning bolt 103 passes through the arc-shaped hole 102. One end of the positioning bolt 103 is fixedly connected to the steam box 301. Heating components 2 are provided on both sides of the mounting bracket 1. The heating components 2 include positioning blocks fixedly connected to one side of the mounting bracket 1. 201. A vertically upward rectangular hole is provided in the positioning block 201. A limiting plate 203 moves through the rectangular hole. A limiting bolt 202 is symmetrically threaded on the outer side of the positioning block 201. The limiting bolt 202 is used to fix the limiting plate 203. Horizontal support frames 204 are fixedly connected to both ends of the limiting plate 203. A fixing plate 205 is fixedly installed in the middle of the support frame 204 by bolts. A heating plate 206 of the same length as the steam box 301 is fixedly installed on one side of each of the two fixing plates 205. A limiting rod 207 of the same length as the steam box 301 is fixedly passed through one end of each of the two support frames 204.

[0041] The positioning plate 101 at one end of the mounting frame 1 is movably connected to both ends of the steam box 301. The arc-shaped hole 102 on the positioning plate 101, in conjunction with the positioning bolt 103, allows the steam box 301 to rotate within a certain range around the positioning bolt 103. By adjusting the angle of the steam box 301, the direction of steam injection can be precisely controlled, ensuring that all positions in the middle layer of the cardboard are fully heated to accommodate cardboard of different specifications and heating requirements. In the heating components 2 on both sides of the mounting frame 1, the positioning block 201 is fixedly connected to the mounting frame 1, and the limiting plate 203 can be positioned within the positioning block 201. The rectangular hole moves vertically up and down. By tightening or loosening the limiting bolts 202 on the outside of the positioning block 201, the height of the limiting plate 203 can be fixed or adjusted, thereby flexibly adjusting the heating plate 206. When the height of the limiting plate 203 is properly adjusted, the heating plate 206 provides auxiliary heating to the upper and lower layers of the cardboard, enhancing the heating effect of the upper and lower layers and making the overall heating of the cardboard more uniform. The installation of the limiting roller 207 can adjust the conveying angle of the cardboard, allowing the cardboard to pass through the surface of the heating plate 206, thereby enhancing the heating effect of the upper and lower layers.

[0042] The implementation principle of the corrugated cardboard tip heating mechanism in this application embodiment is as follows: First, the mounting frame 1 is fixed to the cardboard processing equipment with bolts. In the heating components 2 on both sides of the mounting frame 1, the positioning block 201 is fixed to the mounting frame 1. The limiting plate 203 can move vertically within the rectangular hole of the positioning block 201, and its height is fixed by the limiting bolt 202, thereby adjusting the heating plate 206. Then, after the upper and lower layers of cardboard pass through the limiting roller 207, they adhere to the surface of the heating plate 206 during the conveying process. The steam box 301 is installed below the middle layer of the cardboard. The steam box 301 generates high-temperature steam, and the fan 304... Upon startup, steam is collected through connecting pipe 305 and rectangular collection port 306. The collected steam enters steam box 301 and flows to air ducts 302 on both sides. The top of air duct 302 is inclined inward, and multiple inwardly inclined exhaust ports 303 are evenly distributed. Steam is ejected from exhaust ports 303 at a specific angle to precisely heat the tip of the corrugated cardboard. At the same time, positioning plate 101 at one end of mounting frame 1 is movably connected to both ends of steam box 301. Through arc hole 102 and positioning bolt 103, steam box 301 can rotate around positioning bolt 103 to adjust the steam injection direction and ensure that the middle layer of cardboard is heated evenly.

Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
