Description

Technical Field

[0001] This utility model belongs to the technical field of corrugated cardboard production line equipment, and in particular relates to a preheating device for corrugated rolls in a corrugated cardboard production line. Background Technology

[0002] Corrugated cardboard is a lightweight, high-strength material made of multiple layers of paper bonded together. It is processed into corrugated cardboard from flat cardboard by the upper and lower corrugating rollers of a corrugated cardboard production line (such as a single-facer or a corrugating forming machine).

[0003] Currently, when changing the flute type on a corrugated cardboard production line, the corrugated cardboard box must first have its steam valve closed to release pressure and then be pulled out. The replacement corrugated cardboard box is then inserted, pressurized and fixed, and the steam valve is opened for preheating. Production can only begin after the preheated temperature has been reached. The entire process is lengthy and affects production efficiency, while the energy consumption for starting and stopping the equipment is also significant.

[0004] To address the aforementioned issues, this application proposes a preheating device for corrugated rolls in a corrugated cardboard production line. Utility Model Content

[0005] The purpose of this invention is to provide a preheating device for corrugated rolls in a corrugated cardboard production line, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a preheating device for corrugated rolls in a corrugated cardboard production line, including a frame and a body at its front end. A steam generator is installed below the frame, and corrugated rolls are installed inside the body.

[0008] A lifting unit is installed on the inner side of the machine body, located between the inner side bearing and the frame. The two ends of the corrugated roller have connecting shafts extending out. Multiple sliding blocks that move up and down are movably installed inside the lifting unit. The sliding blocks are rotatably connected to the connecting shafts.

[0009] A steam pipe is installed on one side of the lifting unit, and a connecting pipe connected to a steam generator is installed at the lower end of the steam pipe. An annular cavity is opened inside the corrugated roller, and the annular cavity is connected to the steam pipe through a pipeline.

[0010] Preferably, a set of clamping blocks is installed on one side of the slide block, and adjacent clamping blocks are mated to form a ring mechanism, which is rotatably connected to the adapter shaft.

[0011] Preferably, a rotating shaft is fixed at the center of the corrugated roller, and the rotating shaft is fixedly connected to the two ends of the corrugated roller with sidewalls. The outer side of the sidewall is an annular groove, and a through hole is opened in the sidewall to connect the annular cavity and the annular groove.

[0012] Preferably, a ventilation frame is rotatably installed inside the annular groove, and a steam pipe on one side of the ventilation frame is plugged into and disconnected from a steam pipe.

[0013] Preferably, the surface of the slide has an integral support block, which is fixedly connected to the air vent frame by bolts.

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.

[0030] In the description of this utility model, it should be understood that the terms "opening", "top and bottom", "thickness", "top", "middle", "length", "inner" and "around" indicate the orientation or positional relationship only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] Please see Figure 1-5 As shown, this utility model is a preheating device for corrugated rolls of a corrugated cardboard production line, including a frame 11 and a body 12 at its front end. A steam generator 13 is installed below the frame 11, and a corrugated roll 14 is installed inside the body 12.

[0032] The inner side of the machine body 12 is equipped with a lifting part 15, which is a vertical frame. The internal structure uses a ball screw or screw. It is located between the bearing seat 121 and the frame 11 on the inner side of the machine body 12. The two ends of the corrugated roller 14 have a connecting shaft 18 for detachable connection with the bearing seat 121. Multiple vertically movable slides 17 are movably installed in the lifting part 15. The slides 17 are rotatably connected to the connecting shaft 18. In use, the lifting part 15 drives the upper and lower sets of slides 17 with corrugated roller 14 installed to move up and down at the same time. After the corrugated roller 14 that needs to be replaced is moved out, the corrugated roller 14 that needs to be used is directly moved to the working area.

[0033] A steam pipe 16 is installed on one side of the lifting part 15 and is symmetrically distributed on both sides inside the machine body 12. A connecting pipe 161 is installed at the lower end of the steam pipe 16, one end of which is connected to the steam generator 13 to introduce steam into the interior of the steam pipe 16. A set of two on-off joints are installed on one side of the steam pipe 16 in the upper, middle and lower areas. An annular cavity 142 is opened inside the corrugated roller 14. The annular cavity 142 is connected to the steam pipe 16 through a pipeline to preheat the corrugated roller 14 to be used before switching, so that it can be put into use directly after switching.

[0034] Furthermore, a set of clamping blocks 171 is installed on one side of the slide 17. There are two blocks in a set, one of which is fixed to the slide 17. The adjacent clamping blocks 171 are connected to form a ring mechanism, which is rotatably installed on the outside of the stepped shaft between the adapter shaft 18 and the corrugated tube 14.

[0035] Furthermore, a rotating shaft 141 is fixed at the center of the corrugated roller 14. The rotating shaft 141 is connected and fixed to both ends of the corrugated roller 14 through the side wall. The outer side of the side wall is an annular groove 144. Through holes 143 are opened in the side wall to connect the annular cavity 142 and the annular groove 144. Multiple through holes 143 are evenly distributed around the circumference.

[0036] Furthermore, an air exchange frame 19 is rotatably installed inside the annular groove 144. There is an annular cavity between the side and the side wall of the air exchange frame 19 for temporarily storing steam. When the corrugated roller 14 rotates, multiple through holes 143 pass through the air vent of the air exchange frame 19 in turn, thereby introducing the temporarily stored steam into the interior of the annular cavity 142. A steam pipe 191 is fixedly installed at one end of the air vent of the air exchange frame 19, and one end of the steam pipe 191 is plugged into and disconnected from the on / off connector on the outside of the steam pipe 16.

[0037] Furthermore, a support block is fixed above or below the slide block 17, and bolts are installed inside it. The bolts are fixedly connected to the ventilation frame 19, so that the ventilation frame 19 remains stationary when the corrugated roller 14 rotates, ensuring the stability of the steam flow pipeline.

[0038] Furthermore, both the end of the adapter shaft 18 and the interior of the shaft seat 121 are provided with openings, and an electric telescopic device 181 is installed inside the opening. The movable end of the electric telescopic device 181 is fixed with an adapter block 1811.

[0039] The adapter block 1811 has a square toothed plate extending outward from its outer side, and a square groove is provided on the inner wall of the opening hole. The square toothed plate is engaged with the opening hole, which can transmit the rotational force of the bearing seat 121 to the adapter shaft 18, thereby driving the corrugated roller 14 to rotate.

[0040] Understandably, this utility model can directly preheat the corrugated tube 14 that needs to be switched during production line operation and directly replace it when the production line stops, thereby shortening the switching operation time and enabling continuous production of different types of corrugated paper. This not only improves production efficiency but also reduces the energy consumption caused by equipment start-up and shutdown.

[0041] A specific application of the operation process in this embodiment is as follows: When it is necessary to switch corrugated rollers 14, before all the materials on the current production line have been processed, the two ends of the corrugated rollers 14 are dynamically fixed inside the adjacent clamping blocks 171. Then, the steam pipe 191 is connected to the steam pipe 16 so that steam enters the interior of the annular cavity 142 from the through hole 143 to form a flow, thereby preheating the corrugated rollers 14. After heating is completed, the corrugated rollers 14 to be replaced are directly removed. Under the action of the lead screw inside the lifting part 15, the corrugated rollers 14 are driven down to the predetermined position via the slide block 17. The working position is then adjusted so that the electric telescopic device 181 at its end is inserted into the interior of the bearing seat 121, thereby connecting and fixing the annular cavity 142 to the bearing seat 121. At this time, the rotation of the bearing seat 121 drives the corrugated roller 14 to rotate. During the rotation of the corrugated roller 14, the ventilation frame 19, which is fixed by bolts in the support plate above the slide 17, is fixed inside the annular groove 144. The rotation of the corrugated roller 14 and the ventilation frame 19 form a dynamic and static relationship. The rotating through hole 143 continuously introduces steam into the interior of the annular cavity 142 and discharges it at the other end to form a cycle.
