Description

Technical Field

[0001] The utility model belongs to the technical field of slitting machines, in particular to a slitting machine with a cooling structure. Background Art

[0002] A slitting machine is a mechanical device that can cut wide paper, mica tape or film into multiple narrow materials. It is commonly used in the fields of papermaking, wire and cable mica tape, printing and packaging. It is mainly used for cutting non-woven fabrics, mica tape, paper, insulation materials and various film materials.

[0003] Publication No. "CN220616349U" discloses "a slitting machine with a collecting function". Through the cooperation of a transmission belt, a rotating rod, a cam and an extrusion mechanism, the extrusion plate can squeeze the waste in the collection box and compact the waste paper in the collection box, thereby improving the space utilization rate in the collection box and storing more waste. At the same time, through the rotation of the cam, when the cam rotates to stop squeezing the transmission plate, through the cooperation of the connecting spring, the moving block can drive the transmission plate to move upward and back to its original position, and the extrusion plate can move upward and back to its original position, so that the back and forth squeezing operation can be performed.

[0004] The above-mentioned prior art still has the following disadvantages in the specific implementation process:

[0005] There is a lack of corresponding cooling and heat dissipation structure. When slitting materials, the blades on the slitting machine will come into contact with the materials to be slit. Long-term slitting operations will cause the blades to generate a certain amount of heat. If the heat is not cooled in time, the heated blades will cause curling at the slitting site for some film materials, affecting the slitting quality of the materials and the subsequent use effect. At the same time, the rotating shaft will rotate for a long time, which will also generate heat due to friction, resulting in a reduced service life of the rotating shaft and poor use effect.

[0006] In view of the above problems, we propose a slitting machine with a cooling structure. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model facilitates the slitting knife to rotate through the rotating shaft to perform slitting operations on the materials to be slit, wherein the external cooling water is conveniently introduced into the cooling chamber under the action of the water inlet pipe to cool the heat generated by friction during the rotation of the rotating shaft, and the cooling water after heat exchange is led out in combination with the return water pipe, which facilitates the cooling of the rotating shaft and solves the problem in the prior art that the rotating shaft rotates for a long time and generates heat due to friction, resulting in a reduced service life of the rotating shaft and poor use effect;

Combined with the mutual cooperation of the movable ends of the two baffles and the elastic action of the second spring, the movable ends of the two baffles are abutted against each other, thereby introducing external air into the inner cavity of the shell through the air inlet pipe.

[0017] When the raised portion of the cam is away from the arc block, the slider is squeezed downward under the elastic action of the first spring, and combined with the piston rod, the movable plate is driven to move downward, squeezing the air inside the shell downward. Under the hinged action of the baffle plate and the inner wall of the shell, the two baffle plates are squeezed to both sides, so that the air inside the shell is blown downward through the air outlet to the slitting knife, so as to achieve the purpose of cooling the slitting knife, and solve the problem of the lack of corresponding cooling and heat dissipation structure in the prior art. When the blade on the slitting machine is slitting the material, it will contact the material to be slitting. Long-term slitting operation will cause the blade to generate a certain amount of heat. If the temperature is not cooled and dissipated in time, the heated blade will cause curling at the slitting position of some film materials, affecting the slitting quality of the material and the disadvantages of the later use effect.

[0018] The one-way valve structure on the inner side of the air inlet pipe, combined with the elastic action of the second spring, makes the movable ends of the two baffles counteract each other, ensuring that external air can only enter the shell through the air inlet pipe and be discharged through the air outlet, thereby ensuring the use effect of the blowing mechanism. At the same time, the filter plate at the air inlet of the air inlet pipe prevents dust in the external air or waste generated in the cutting process from entering the air inlet pipe, causing blockage of the air inlet pipe and affecting the use effect.

[0029] The rotating shaft 2 is convenient for driving the slitting knife 3 to rotate, and the slitting operation is carried out on the material to be slit. Under the action of the water inlet pipe 20, external cooling water is conveniently introduced into the cooling chamber 4 to cool the heat generated by friction during the rotation of the rotating shaft 2. At the same time, the cooling water after heat exchange is led out in combination with the return pipe 19, which facilitates the cooling of the rotating shaft 2. The sealing cover 5 is rotatably connected to the rotating shaft 2 to ensure the normal rotation of the rotating shaft 2. At the same time, one end of the cooling chamber 4 is sealed to avoid leakage of cooling water when the rotating shaft 2 is cooled.

[0030] The air blowing mechanism includes a slider 8, a piston rod 9, a movable plate 10, an air inlet pipe 11, an arc block 13, a cam 14 and a first spring 15. Slide grooves 7 are provided on both sides of the support frame 1. The slider 8 is slidably arranged in the slide groove 7. The movable plate 10 is movably arranged on the upper side of the inner part of the shell 6. The two piston rods 9 are slidably matched with the shell 6, and the upper and lower ends of the piston rod 9 are respectively fixedly connected to the movable plate 10 and the slider 8.

[0032] Through the mutual cooperation between the cam 14 and the arc block 13, combined with the sliding cooperation between the slider 8 and the slide groove 7, when the raised portion of the cam 14 is close to the arc block 13, it is convenient to push the arc block 13 upward, drive the slider 8 to squeeze the first spring 15, and at the same time, under the action of the piston rod 9, the movable plate 10 is pushed upward to form a suction action inside the shell 6.

[0033] A water tank 21 is provided on one side of the support frame 1, and a water pump 22 is installed on the top of the water tank 21 through a water pumping pipe. The water outlet end of the water pump 22 is connected to the lower end of the water inlet pipe 20, and the end of the return pipe 19 away from the sealing cover 5 is connected to the water tank 21. The water tank 21 is connected with a water injection pipe and a drainage pipe, which is convenient for adding water to the inside of the water tank 21 and draining the water inside the water tank 21 after use. A transparent plate is provided on the surface of the water tank 21 to facilitate observing the water level inside the water tank 21.

[0034] Two tensioning rollers 23 are installed on the inner side of the support frame 1 through an electric push rod, which is convenient for adjusting the tension degree of the material to be cut and ensures the cutting effect. An L bracket is fixed on the side of the support frame 1 away from the sealing cover 5, and a motor 24 is installed on the inner side of the L bracket. The output end of the motor 24 is connected to the end of the rotating shaft 2 away from the sealing cover 5.

[0035] Example:

[0036] When non-woven fabrics, mica tapes, paper, insulating materials and various film materials need to be slid, the height of the two tensioning rollers 23 is first adjusted under the action of the electric push rod to ensure the tension of the material passing under the rotating shaft 2, and the motor 24 is started at the same time, and the rotating shaft 2 is driven by the motor 24 to rotate, thereby driving the slitting knife 3 to rotate synchronously, so as to achieve the purpose of slitting the material passing under the rotating shaft 2;

[0037] During the slitting operation, when the rotating shaft 2 and the slitting knife 3 need to be cooled, the water pump 22 is started, and the cooling water in the water tank 21 is pumped out through the pumping pipe, and enters the cooling chamber 4 through the water inlet pipe 20, so as to cool the heat generated by the friction during the rotation of the rotating shaft 2. As the cooling water level in the cooling chamber 4 rises, when the cooling water level rises to the height of the return pipe 19, it is discharged through the return pipe 19 and flows back into the water tank 21, so that the circulation of the cooling water in the cooling chamber 4 is realized, and the cooling effect of the rotating shaft 2 is ensured, which solves the problem in the prior art that the rotating shaft rotates for a long time, and the friction heats up, resulting in a reduction in the service life of the rotating shaft and a poor use effect.

[0038] Under the connection between the cooling pipe 18 and the water inlet pipe 20, part of the cooling water flowing through the water inlet pipe 20 enters the cooling pipe 18 to cool the inner cavity of the shell 6. At the same time, under the connection between the cooling pipe 18 and the return water pipe 19, the circulation of the cooling water in the cooling pipe 18 is realized.

[0039] During the rotation of the rotating shaft 2, the cam 14 is driven to rotate. When the raised portion of the cam 14 is close to the arc block 13, the arc block 13 is pushed upward. Combined with the sliding cooperation between the slider 8 and the slide groove 7, the slider 8 is driven to press the first spring 15 upward. At the same time, under the action of the piston rod 9, the movable plate 10 is pushed upward to form a suction action inside the shell 6. Combined with the mutual cooperation of the movable ends of the two baffles 16 and the elastic action of the second spring 17, the movable ends of the two baffles 16 are abutted against each other, thereby introducing the external air into the inner cavity of the shell 6 through the air inlet pipe 11;

[0040] When the raised portion of the cam 14 is away from the arc block 13, the slider 8 is squeezed downward under the elastic action of the first spring 15, and combined with the piston rod 9, the movable plate 10 is driven to move downward, squeezing the air inside the shell 6 downward. Under the hinged action of the baffle 16 and the inner wall of the shell 6, the two baffles 16 are squeezed to both sides, and the second spring 17 is compressed, and the circulation of cooling water inside the cooling pipe 18 is coordinated, so that the cold air inside the shell 6 is blown downward through the air outlet 12 to the slitting knife 3, so as to achieve the purpose of cooling the slitting knife 3, and solve the problem of lack of corresponding cooling and heat dissipation structure in the prior art. When the blade on the slitting machine slits the material, it will contact the material to be slit. Long-term slitting operation will cause the blade to generate a certain amount of heat. If the cooling and heat dissipation are not performed in time, the heated blade will cause curling at the cutting position of some film materials, affecting the slitting quality of the material and the disadvantages of the later use effect.
