DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the utility model will be further described below with reference to the drawings and embodiments.

[0020] As Figures 1-4 shown, an embodiment of the utility model provides a polyethylene tape slitter, including:

[0021] A mounting frame 1, on which an unwinding roller 14 is rotatably connected. There is a cutting mechanism between the unwinding roller 14 and the transmission pipe 9. The cutting mechanism includes a cutting knife, a fixed seat, a driving motor (not shown in the figure), etc. This part is prior art and will not be elaborated here in detail.

[0022] Fixing mechanism, the fixing mechanism includes a transmission pipe 9 rotatably installed on the mounting frame 1, and a plurality of fixing members are fixedly installed on the transmission pipe 9. The fixing members include an air outlet 20 penetrating through the transmission pipe 9. Among them, the number of air outlets 20 is set to 3; a piston cylinder 11 communicating with the air outlet 20 is fixedly installed on the transmission pipe 9. A first spring 17 is fixedly installed in the piston cylinder 11. The pulling force of the first spring 17 can drive the piston 19, the connecting rod 18 and the support plate 10 to reset. The first spring 17 is fixedly installed with a piston 19 that slidably abuts against the inner wall of the piston cylinder 11. A connecting rod 18 is fixedly installed on the piston 19, and a semi-cylindrical support plate 10 is fixedly installed on the connecting rod 18, which can abut against the tape winding cylinder.

[0023] A gas supply mechanism capable of supplying gas into the transmission pipe 9 is installed on one side of the mounting frame 1. The gas supply mechanism includes an air pump 2 provided on one side of the mounting frame 1. The air pump 2 is fixedly connected with a ventilation pipe 4. The ventilation pipe 4 is rotatably connected with the transmission pipe 9. The ventilation pipe 4 is fixedly connected with a rotary joint 5, and the rotary joint 5 is fixedly connected with the transmission pipe 9.

[0024] The air pump 2 will send air into the transmission pipe 9 through the ventilation pipe 4. The air enters the fixing member through the transmission pipe 9. The air will push the piston 19 to move upward in the piston cylinder 11. The piston 19 will drive the connecting rod 18 and the support plate 10 to move, so as to abut against the inner wall of the tape winding cylinder. The pressure exerted by the air on the piston 19 can make the support plate 10 exert a certain pressure on the tape winding cylinder, so as to fix the tape winding cylinder; among them, a rubber pad is fixed on the outer wall of the support plate 10 to increase the friction with the tape winding cylinder.

[0025] It also includes a rotating mechanism. The rotating mechanism includes a motor 3 fixedly installed on the mounting frame 1. Transmission wheels 6 are fixedly installed on the output end of the motor 3 and the transmission pipe 9 respectively. The two transmission wheels 6 are connected by a conveyor belt 8. Among them, the transmission wheel 6 can be a sprocket, and the conveyor belt 8 is a chain. The purpose is to achieve stable transmission between the transmission wheel 6 and the conveyor belt 8. The transmission method is not limited to this.

[0026] The transmission end of the motor 3 will drive the transmission wheel 6 and the conveyor belt 8 to rotate. The transmission wheel 6 will drive the transmission pipe 9 to rotate. The transmission pipe 9 will drive the fixing member to rotate. The tape on the unwinding roller 14 will be wound around the fixing member after being sheared. The rotation of the fixing member will drive the rotation of the unwinding roller 14, so as to continuously pull the tape.

[0027] It further includes a disassembly mechanism. The disassembly mechanism includes a fixed block 12 rotatably mounted on the transmission pipe 9. A chute 16 is provided on the fixed block 12. A pull rod 13 is slidably connected to the chute 16. The pull rod 13 is slidably arranged through the mounting frame 1. A limit block 15 is fixedly connected to the pull rod 13. A second spring 7 is fixedly installed between the limit block 15 and the mounting frame 1. The pulling force of the second spring 7 can make the pull rod 13 abut against the chute 16 to keep the pull rod 13 stable in the chute 16. At the same time, when the limit block 15 is pulled, the limit block 15 will pull out the pull rod 13 from the chute 16, thus forming an opening through which the made tape can be removed.

[0028] The detailed working process of the present utility model is as follows:

[0029] During use, the limit block 15 is pulled. The limit block 15 will pull out the pull rod 13 from the chute 16, thus forming an opening. The tape take-up reel is placed on the support plate 10 through the opening. There are protrusions on the side wall of the support plate 10. When the tape take-up reel is sleeved on the support plate 10, it abuts against the protrusions, which can ensure that the tape take-up reel is aligned with the tape to be wound, guaranteeing that the tape will not shift during the tape processing and avoiding unqualified tapes produced. After the tape take-up reel is placed, when the chute 16 in the fixed block 12 corresponds to the pull rod 13, the limit block 15 is released. Under the action of the second spring 7, the limit block 15 and the pull rod 13 are reset. The pull rod 13 is inserted into the chute 16 to complete the fixation, thus completing the installation.

[0030] The staff turns on the air pump 2. The air pump 2 will discharge air into the ventilation pipe 4 and the transmission pipe 9. The air enters the piston cylinder 11 through the air outlet 20. As the air enters, the pressure brought by the air will push the piston 19 to move. The piston 19 will drive the support plate 10 to move until it abuts against the tape take-up reel. With the push of the piston 19, the support plate 10 can keep the tape take-up reel stable. The motor 3 is turned on. The output end of the motor 3 will drive the transmission wheel 6 and the conveyor belt 8 to rotate. The transmission wheel 6 will drive the transmission pipe 9 to rotate. The transmission pipe 9 will drive the fixing member to rotate. The rotation of the fixing member will drive the rotation of the unwinding roller 14. The tape will be continuously cut and wound around the tape take-up reel on the support plate 10.

[0031] After the tape processing is completed, turn off the air pump 2. An exhaust pipe can be installed on the air pipe 4, and a valve is installed on the exhaust pipe. Open the valve, the first spring 17 will drive the piston 19 to reset, the air will flow out of the piston cylinder 11, the piston 19 will drive the connecting rod 18 to reset, and the connecting rod 18 will drive the support plate 10 to reset, so that the air in the transmission pipe 9 is discharged through the exhaust pipe; the tape winding reel can be removed from the support plate 10, and at the same time, the limit block 15 is pulled to move, and the limit block 15 will pull the pull rod 13 out of the chute 16, and the fixed block 12 is no longer limited, and there is a gap between the mounting frame 1 and the fixed block 12, so that the tape winding reel can be removed from the transmission pipe 9 to complete the collection of the tape. Repeating this work can continuously process the tape.

[0032] The utility model uses the cooperation between the air pump 2 and the fixing structure to fix and relax the tape winding reel. At the same time, the disassembly structure is used to facilitate the disassembly of the tape winding reel, reducing the work process and the labor intensity of the staff.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
