Description

Technical Field

[0001] This invention relates to the field of roll slitting equipment technology, and in particular to a slitting mechanism with a heating function. Background Technology

[0002] Vapor phase corrosion inhibitor paper is a special rust-preventive packaging material made from special neutral paper as the base material, coated with different formulations of special substances—vapor phase corrosion inhibitors (VCI), and processed through a series of post-processing steps. After processing, vapor phase corrosion inhibitor paper is often stored in large rolls and is slit into smaller rolls as needed before sale.

[0003] Similar to existing roll slitting, vapor phase rust inhibitor paper is slitted on a slitting machine. One end of the vapor phase rust inhibitor paper is fixed on the slitting roller, and then the drive unit drives the slitting roller to rotate so that the roll material is wound onto the slitting roller. When the material on the slitting roller is wound to a certain length, it is cut off by the slitting mechanism on the slitting machine.

[0004] The existing slitting mechanism includes a lifting mechanism, a blade holder, and a slitting blade. The slitting blade is mounted on the blade holder, and the lifting mechanism drives the blade holder to rise and fall to cut the material. Vapor phase rust inhibitor paper has a rust-preventive layer, therefore it needs to be stored in a dry environment, and the wound vapor phase rust inhibitor paper should also be kept as dry as possible.

[0005] Therefore, the present invention proposes a slitting mechanism with heating function. Summary of the Invention

[0006] To address the technical problems existing in the background art, the present invention proposes a slitting mechanism with heating function.

[0007] The present invention proposes a slitting mechanism with heating function, including a frame and a blade holder. The blade holder is mounted on the frame via a lifting mechanism. The mechanism also includes an upper heating roller and a lower heating roller. Both the upper heating roller and the lower heating roller are laterally rotatably mounted on the frame, with the upper heating roller located above the lower heating roller. A material guiding channel is formed between the lower heating roller and the upper heating roller.

[0008] The upper heating roller has an upper guide through hole along its radial direction, and the lower heating roller has a lower guide through hole along its radial direction; when the upper guide through hole is perpendicular to the material guiding channel, the lower guide through hole is perpendicular to the material guiding channel.

[0009] The cutter holder can move within the lower guide through hole or the upper guide through hole. Those skilled in the art should understand that when the cutter holder is above the upper heating roller, it moves within the upper guide through hole to cut the material, and when the cutter holder is below the lower heating roller, it moves within the lower guide through hole.

[0010] Preferably, the height of the material guiding channel is maximized when the upper guide through hole and the lower guide through hole are opposite each other.

[0011] Preferably, it further includes a driving mechanism, which drives the lower heating roller and the upper heating roller to rotate at the same speed but in opposite directions.

[0012] Preferably, the upper heating roller and / or the lower heating roller have heating chambers containing heated gas, and the inner walls of the upper guide through hole and / or the lower guide through hole have gas guide holes communicating with the heating chambers.

[0013] Preferably, when the cutter head moves within the lower guide through hole to cut material, gas is discharged through the vent hole of the upper guide through hole;

[0014] When the cutter head moves within the upper guide hole to cut material, gas is discharged through the air vent of the lower guide hole.

[0015] Preferably, the device further includes a guide roller, which is rotatably mounted on the frame and is used to guide the material passing through the upper heating roller and the lower heating roller.

[0016] Preferably, the outer diameter of the guide roller is larger than the outer diameters of the upper heating roller and the lower heating roller, and the axis of the guide roller is located vertically between the axis of the upper heating roller and the axis of the lower heating roller.

[0017] Preferably, the guide roller has a negative pressure chamber, and the outer wall of the guide roller has an adsorption hole communicating with the negative pressure chamber. The negative pressure chamber is connected to an exhaust fan through a pipe. The discharge end of the exhaust fan is connected to an air dryer through a pipe. The discharge end of the air dryer is connected to a gas heater. The discharge end of the gas heater is connected to the heating chamber through a pipe.

[0018] Preferably, when the lower heating roller and the upper heating roller stop rotating, the lifting mechanism drives the knife holder to move within the lower guide through hole or the upper guide through hole.

[0019] Preferably, when the tool holder moves within the upper guide through hole or the lower guide through hole, the temperature of the upper heating roller and the lower heating roller is higher than the temperature of the rotating upper heating roller and the lower heating roller.

[0020] In this invention, the proposed slitting mechanism with heating function heats the material through a guide channel between the upper and lower heating rollers, thereby achieving material drying; further, the material is heated by high-temperature gas discharged from the upper and lower heating rollers; the friction between the upper and lower heating rollers and the material is changed by the upper and lower guide holes during the material transport process, thereby increasing the transport efficiency; at the same time, the frame moves within the upper or lower guide channel to prevent the upper or lower heat-conducting rollers from rotating relative to the material during the cutting process, thereby increasing the cutting accuracy and cutting effect; furthermore, the setting of the heating chamber and air guide holes further enhances the heating effect and the material leveling effect.

[0021] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0028] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] like Figures 1-5The slitting mechanism with heating function shown includes a frame 1 and a blade holder 2. The blade holder 2 is mounted on the frame 1 via a lifting mechanism 3. Similar to the prior art, the frame 1 is also equipped with a discharge roller and a dividing roller that are mounted laterally. A motor is mounted on the dividing roller to drive the dividing roller to rotate, so that the material on the discharge roller is wrapped around the dividing roller. After the material on the dividing roller has been wrapped around for a certain distance, the blade holder 2 cuts the material.

[0030] Similar to existing technologies, the tool holder 2 includes a frame 20 and a cutting blade 21. The cutting blade 21 is mounted on the frame 20, and the lifting end of the lifting mechanism 3 is mounted on the frame 20. The lifting mechanism 3 can be a component that can achieve lifting, such as an electric cylinder or a hydraulic cylinder in the prior art. In this embodiment, the lifting mechanism 3 is a hydraulic cylinder.

[0031] It also includes an upper heating roller 4 and a lower heating roller 5. The outer diameters of the upper heating roller 4 and the lower heating roller 5 are equal. The upper heating roller 4 and the lower heating roller 5 are both rotatably mounted on the frame 1, and the upper heating roller 4 is located above the lower heating roller 5. A material guiding channel is formed between the lower heating roller 5 and the upper heating roller 4.

[0032] The upper heating roller 4 has an upper guide through hole 40 along its radial direction. Specifically, the two ends of the upper heating roller 4 are rotatably mounted on the frame 1, and the upper heating roller 4 has an upper guide through hole 40 in its middle. The axis of the upper heating roller 4 is located in the middle dividing surface of the upper guide through hole 40. The lower heating roller 5 has a lower guide through hole 50 along its radial direction. Specifically, the two ends of the lower heating roller 5 are rotatably mounted on the frame 1, and the lower heating roller 5 has a lower guide through hole 50 in its middle. The axis of the lower heating roller 5 is located in the middle dividing surface of the lower guide through hole 50. When the upper guide through hole 40 is perpendicular to the material guide channel, the lower guide through hole 50 is perpendicular to the material guide channel.

[0033] The lengths of the upper guide through hole 40 and the lower guide through hole 50 along the axial direction of the upper heating roller 4 and the lower heating roller 5 are greater than the width of the material.

[0034] The blade holder 2 can move within the lower guide through hole 50 or the upper guide through hole 40. Specifically, if the blade holder 2 is located above the upper heating roller 4, then the blade holder 2 moves within the upper guide through hole 40. The lifting mechanism 3 drives the blade holder 2 to move downward to cut the material. In this embodiment, the blade holder 2 is located below the lower heating roller 5, and the blade holder 2 moves within the lower guide through hole 50. The lifting mechanism 3 drives the blade holder 2 to move upward to cut the material.

[0035] When the upper heating roller 4 and the lower heating roller 5 are not provided with upper guide holes 40 and lower guide holes 50, they are cylindrical. When the upper guide hole 40 and the lower guide hole 50 are provided on the lower heating roller 5, the height of the material guide channel is at its maximum when the upper guide hole 40 and the lower guide hole 50 are opposite each other. During the material guiding process, when the upper guide hole 40 and the lower guide hole 50 are not opposite to the material (i.e., when the upper guide hole 40 and the lower guide hole 50 are not opposite to each other), the upper heating roller 4 and the lower heating roller 5 heat the material and exert a certain squeezing effect, leveling and drying the material. When the upper guide hole 40 and the lower guide hole 50 are opposite to each other during the material guiding process, the upper heating roller 4 and the lower heating roller 5 do not directly contact the material, thereby achieving spaced leveling and guidance of the material, which facilitates material transmission to a certain extent.

[0036] At the same time, during the cutting process, the blade holder 2 extends into the lower guide channel to cut the material located opposite the lower guide channel and the upper guide channel. The cutting blade 21 of the blade holder 2 can extend into the upper guide channel to ensure the cutting effect. During the cutting process, the blade holder 2 is heated by the lower heat-conducting roller to achieve a high temperature of the cutting blade 21 during cutting, which to a certain extent achieves the technical effect of heat sealing the material.

[0037] In some preferred embodiments, the system further includes a drive mechanism 6, which drives the lower heating roller 5 and the upper heating roller 4 to rotate at the same speed but in opposite directions. The drive mechanism 6 includes a motor and a transmission mechanism, which is a gear transmission mechanism. The motor drives the lower heating roller 5 to rotate laterally. The gear transmission mechanism includes a driving gear and a driven gear. The driving gear is mounted on the lower heating roller 5, and the driven gear is mounted on the upper heating roller 4. The driving gear and the driven gear mesh to ensure that the upper heating roller 4 and the lower heating roller 5 rotate at the same speed but in opposite directions, which facilitates the transfer of materials.

[0038] Preferably, the upper heating roller 4 and / or the lower heating roller 5 have heating chambers containing heated gas. The inner walls of the upper guide through hole 40 and / or the lower guide through hole 50 are provided with air guide holes communicating with the heating chambers. In this embodiment, the heating chamber includes an upper heating chamber 41 and a lower heating chamber 51. The upper heating chamber 41 is located on the upper heating roller 4, and the lower heating chamber 51 is located on the lower heating roller 5. The air guide holes include an upper air guide hole 42 and a lower air guide hole 52. The upper air guide hole 42 is located on the inner wall of the upper guide through hole 40 and communicates with the upper heating chamber 41. The lower air guide hole 52 is located on the inner wall of the lower heat conduction through hole and communicates with the lower heating chamber 51.

[0039] During operation, externally heated drying gas is transmitted to the upper heating chamber 41 and the lower heating chamber 51 through a rotary joint. The high-temperature gas in the upper heating chamber 41 and the lower heating chamber 51 heats the upper heating roller 4 and the lower heating roller 5. At the same time, the high-temperature gas is discharged through the upper air guide hole 42 and the lower air guide hole 52 into the upper guide through hole 40 and the lower guide through hole 50 and then discharged through the upper guide through hole 40 and the lower guide through hole 50. As the upper heating roller 4 and the lower heating roller 5 rotate, the upper guide through hole 40 and the lower guide through hole 50 also rotate, thereby blowing the material with the gas in the upper guide through hole 40 and the lower guide through hole 50 to further facilitate the leveling and drying of the material.

[0040] Preferably, when the tool holder 2 moves within the lower guide through hole 50 to cut material, gas is discharged through the air vent of the upper guide through hole 40;

[0041] When the cutter holder 2 moves within the upper guide hole 40 to cut the material, the air vent of the lower guide hole 50 discharges gas. This further facilitates increasing the cutting effect. In this embodiment, since the cutter holder 2 moves within the lower guide hole 50 to cut the material, when cutting (when the cutting blade 21 just contacts the material and the cutting blade 21 moves upward), the upper guide hole 40 discharges heated gas, and no more gas is introduced into the lower heating chamber 51, that is, no heated gas is discharged from the lower guide hole 50.

[0042] To further enhance the slitting effect, preferably, a guide roller 7 is also included. The guide roller 7 is rotatably mounted on the frame 1 and is used to guide the material passing through the upper heating roller 4 and the lower heating roller 5. The material passes through the upper heating roller 4, the lower heating roller 5 and the guide roller 7 and then winds onto the slitting roller.

[0043] Preferably, the outer diameter of the guide roller 7 is larger than the outer diameters of the upper heating roller 4 and the lower heating roller 5, and the axis of the guide roller 7 is located between the axis of the upper heating roller 4 and the axis of the lower heating roller 5 in the vertical direction. This increases the heating and drying capacity of other materials discharged from the upper guide hole 40 and the lower guide hole 50, and also enhances the connection effect.

[0044] Preferably, the guide roller 7 has a negative pressure chamber 70, and the outer wall of the guide roller 7 has an adsorption hole 71 that communicates with the negative pressure chamber 70. Multiple sets of adsorption holes 71 are provided and distributed on the outer wall of the guide roller 7. The negative pressure chamber 70 is connected to an exhaust fan 8 through a pipe. The discharge end of the exhaust fan 8 is connected to an air dryer 9 through a pipe. The discharge end of the air dryer 9 is connected to a gas heater 10. The discharge end of the gas heater 10 is connected to a heating chamber through a pipe, which further increases the leveling and drying effect of the material. Moreover, after the material is cut, it can still pass through the guide roller 7 and then be wound onto the distribution roller.

[0045] Preferably, when the tool holder 2 moves within the upper guide through hole 40 or the lower guide through hole 50, the temperature of the upper heating roller 4 and the lower heating roller 5 is higher than the temperature of the rotating upper heating roller 4 and the lower heating roller 5.
