Description

Technical Field

[0001] The utility model relates to the technical field of slitting equipment, in particular to a protective film slitting machine with good molding effect. Background Art

[0002] Slitting machine is a mechanical device that cuts wide paper, mica tape or film into multiple narrow materials. It is commonly used in papermaking machinery, wire and cable mica tape and printing and packaging machinery. Slitting machine is mainly used for: non-woven fabrics; mica tape, paper, insulation materials and various film materials, especially suitable for narrow tape (non-woven fabrics, paper, insulation materials, mica tape, film, etc.).

[0003] When the slitting machine is slitting the protective film, the blade head and the protective film are always in a state of friction, resulting in rapid and serious wear of the blade head. When replacing the blade head of most slitting machines, auxiliary tools are needed to remove screws and other parts, and cumbersome disassembly steps are performed. It is very easy to waste time during the replacement process, resulting in reduced production efficiency, and this replacement effect is not good.

[0004] At the same time, when the cutter head is cutting the protective film, since there is no cooling setting, the temperature of the cutter head will gradually increase during operation. The staff needs to stop the equipment to cool down the cutter head, otherwise the protective film will be deformed under the action of high temperature, resulting in poor forming effect of the protective film. Utility Model Content

[0005] The purpose of the utility model is to provide a protective film slitting machine with good molding effect, so as to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: A protective film slitting machine with good molding effect, comprising a machine body and a sliding shell fixed on both sides of the inner wall thereof, and also comprising:

[0007] A mounting seat sliding on one side of the inner wall of the sliding shell, a fixing frame fixedly connected to one side of the surface of the mounting seat, a mounting groove opened on one side of the surface of the fixing frame, a cutter head slidingly connected to the inner wall of the mounting groove, and a limiting mechanism installed on one side of the surface of the fixing frame;

[0008] A connecting groove is opened on one side of the surface of the fixing frame, a positioning mechanism is arranged on one side of the surface of the fixing frame, a fixing rod is fixedly connected above the surface of the mounting seat, an injection mechanism is fixedly connected to the surface above the fixing rod, a connecting shell is fixedly connected to one side of the bottom surface of the fixing frame, and a collecting shell is slidably connected below the connecting shell.

[0009] Preferably, the limiting mechanism includes a sliding groove opened on one side of the fixing frame and a baffle sliding on the inner wall thereof, and also includes a first spring fixed to one side of the inner wall of the connecting groove and a push-pull rod fixed to the other end thereof.

[0010] Preferably, the positioning mechanism includes a fixing block fixed to one side of the fixing frame surface and a groove opened on the surface thereof, and also includes a second spring fixed to the bottom of the inner wall of the groove and a blocking frame fixed to the other end thereof.

[0011] Preferably, the jet mechanism includes a casing fixed to the top of the fixing rod and an air inlet frame fixed to one side of its surface, and also includes an air inlet fan fixed to one side of the air inlet frame and a refrigeration assembly fixed to the inner wall of the casing, and a pipeline is provided on one side of the surface of the casing.

[0012] Preferably, a pull rod is fixedly connected below the blocking frame, and the pull rod is located inside the second spring.

[0013] Preferably, the pipe is used in conjunction with a cutter head, and the air outlet of the pipe is located above the cutting point of the cutter head.

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

[0015] The utility model uses a limiting mechanism in cooperation with a positioning mechanism. When a worker replaces a cutter head, there is no need to use complicated disassembly tools for disassembly, so that the worker can quickly replace the cutter head, which reduces the replacement time required by the worker and improves work efficiency. At the same time, when the slitting machine is running, with the cooperation of the jet mechanism and the cutter head, the cold air generated by the jet mechanism can cool the cutter head, so that it will not generate high temperature due to friction with the protective film, causing the protective film to deform when the temperature is too high. The slitting machine is more stable during operation, which solves the problem that it is troublesome to replace the cutter head of the existing slitting machine and the overheating of the cutter head causes a poor forming effect of the protective film.

An air jet mechanism 12 is fixedly connected to the upper surface of the fixing rod 11. The air jet mechanism 12 is used in conjunction with the cutter head 6. Under the action of the air jet mechanism 12, the temperature generated by friction can be reduced when the cutter head 6 cuts the protective film, and the generated waste can be guided. A connecting shell 13 is fixedly connected to one side of the bottom surface of the fixing frame 4. The connecting shell 13 is used in conjunction with the air jet mechanism 12. Under the action of the air jet mechanism 12, the waste can be blown into the connecting shell 13. A collecting shell 14 is slidably connected to the lower part of the connecting shell 13. Both sides of the surface of the collecting shell 14 are fixedly connected to the inner wall of the body 1. Under the action of the inclination of the connecting shell 13, the internal waste can be transferred into the collecting shell 14 for collection, which reduces the time required for the staff to clean up the waste and reduces the workload of the staff.

[0025] When the locking cam 72 is in the unlocking state, the locking cam 73 is in the unlocking state, and the locking cam 73 is in the unlocking state, so that the locking cam 73 can be unlocked easily.

[0026] The positioning mechanism 9 includes a fixing block 91, one side of the surface of the fixing block 91 is fixedly connected to one side of the surface of the fixing frame 4, and a groove 92 is opened on the surface of the fixing block 91. The bottom of the inner wall of the groove 92 is fixedly connected to a second spring 93, and the other end of the second spring 93 is fixedly connected to a blocking frame 94. A pull rod 10 is fixedly connected below the blocking frame 94, and the pull rod 10 is located inside the second spring 93, which can prevent the second spring 93 from having a large position displacement when it is stretched or contracted. When the staff needs to remove the cutter head, the pull rod 10 is pulled down, and the pull rod 10 drives the blocking frame 94 to descend, and the blocking frame 94 drives the second spring 93 to compress, so that the blocking frame 94 descends to release the obstruction of the baffle 72 and allows it to pass. When the baffle 72 moves to the other side of the blocking frame 94, the blocking frame 94 returns to its original position under the action of the second spring 93, and the baffle 72 is limited under the action of the blocking frame 94 so that it cannot return to its original position, which is convenient for the staff to replace the cutter head 6.

[0027] The jet mechanism 12 includes a casing 121, the bottom of which is fixedly connected to the top of the fixing rod 11, an air inlet frame 122 is fixedly connected to one side of the surface of the casing 121, an air inlet fan 123 is fixedly connected to one side of the air inlet frame 122, and a refrigeration component 124 is fixedly connected to the inner wall of the casing 121, under which the wind can be cooled, a pipe 125 is connected to the surface of one side of the casing 121, and the pipe 125 is used in conjunction with the cutter head 6, and the air outlet of the pipe 125 is located above the cutting point of the cutter head 6, under which the refrigerated wind cools the cutter head 6 to prevent the cutter head 6 from being overheated and causing the protective film to deform.

[0028] It is worth noting that the technical features such as the refrigeration component 124 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected according to conventional methods in the field, and this technical solution will not be further elaborated.

[0029] Working principle: when the staff needs to remove the cutter head 6, they first pull the push rod 74, which drives the first spring 73 to stretch and drives the baffle 72 to move. When the baffle 72 moves to a certain position, the pull rod 10 is pulled to drive the blocking frame 94 to descend, and at the same time drives the second spring 93 to compress, so as to release the blocking frame 94 from limiting the cutter head 6. When the baffle 72 passes the blocking frame 94, under the action of the second spring 93, the blocking frame 94 is driven to return to its original position, and the baffle 72 is limited again. The staff can slide the cutter head 6 out of the installation slot 5 for replacement without The complicated disassembly steps are carried out to increase the replacement speed of the staff and improve the work efficiency. After the replacement is completed, the pull rod 10 is pulled again to release the limit on the baffle 72 of the blocking frame 94. Under the action of the first spring 73, the baffle 72 returns to its original position to block the cutter head 6. When the slitting machine is running, the air inlet fan 123 is turned on, and the air is cooled under the action of the refrigeration component 124. The refrigerated air is sprayed out through the pipe 125 to cool the cutter head 6, so that the temperature of the cutter head 6 will not be too high, thereby reducing the deformation of the protective film when the temperature is too high, so that the protective film formed by cutting is better.
