Description

Technical Field

[0001] This utility model relates to the field of seat belt cutting technology, specifically a wear-resistant textile belt cutting device. Background Art

[0002] Seat belts are safety components used in vehicles or airplanes. They are made of wear-resistant materials through textile manufacturing. The required length of seat belts varies depending on the environment they are used in. For child car seats, the length of the seat belt cut into sections is shorter.

[0003] Existing cutting devices sometimes rely on visual observation of the seatbelt's length for cutting, resulting in slight deviations in length, though this doesn't affect usability. However, manual observation and cutting significantly increases labor intensity. Consequently, some factories use fully automatic cutting devices. But these devices require stopping the feeding mechanism during cutting operations, and different power sources are needed for conveying on the worktable and the cutting process, making the overall operation quite cumbersome. Utility Model Content

[0004] The purpose of this invention is to provide a wear-resistant textile belt cutting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant textile belt cutting device, comprising a working frame, a conveyor belt installed at one end of the working frame, a rotating rod rotatably installed in the middle of the working frame via a bearing, a compression conveying roller fixedly installed in the middle of the rotating rod, the compression conveying roller being used to compress and convey the textile belt, a motor fixedly installed on one side of the working frame corresponding to the position of the rotating rod, the output end of the motor passing through the working frame and fixedly connected to one end of the rotating rod, limit frames symmetrically fixedly installed at the end of the working frame away from the conveyor belt, a blade holder slidably installed between the two limit frames, and an ultrasonic cutter fixedly installed at the bottom of the blade holder.

[0006] As a further preferred embodiment of this technical solution, cams are symmetrically fixedly installed at both ends of the rotating rod, and a first sliding hole is symmetrically opened in the middle of the work frame corresponding to the position of the cam. A first sliding rod is slidably installed inside the first sliding hole, and a connecting rod is rotatably installed at the bottom of the first sliding rod through a shaft pin. The end of the connecting rod away from the first sliding rod is rotatably connected to one side of the tool holder through a shaft pin.

[0007] As a further preferred embodiment of this technical solution, the cam's protrusion is circular, and the center of the cam's protrusion coincides with the central axis of the rotating rod.

[0008] As a further preferred embodiment of this technical solution, the tool holder has symmetrical second sliding holes at both ends, and a second sliding rod is fixedly installed on the work frame at the position corresponding to the second sliding hole. The second sliding rod is slidably connected to the second sliding hole, and a return spring is sleeved on the outer side of the bottom end of the second sliding rod. One end of the return spring is fixedly connected to the tool holder, and the other end of the return spring is fixedly connected to the work frame.

[0009] As a further preferred embodiment of this technical solution, the work frame has symmetrically provided positioning holes at the middle position near the extrusion conveyor roller. Positioning rods are slidably installed inside the positioning holes. Lifting rods are fixedly installed on the top of the two positioning rods. A compression spring is sleeved on the outer side of the bottom end of the positioning rod. One end of the compression spring is fixedly connected to the bottom end of the positioning rod, and the other end of the compression spring is fixedly connected to the work frame.

[0010] As a further preferred embodiment of this technical solution, the work frame is fixedly installed at equal intervals at one end near the conveyor belt with fixing rods for limiting the horizontal position of the textile belt.

[0011] This utility model provides a wear-resistant textile tape cutting device, which has the following beneficial effects:

[0012] (1) This utility model discharges material through the discharge assembly. The operation of the motor drives the rotating rod to rotate, which in turn drives the extrusion conveyor roller to extrude and convey the textile belt. During this process, the cam intermittently extrudes the top of the first slide rod, which drives the ultrasonic cutter to reciprocate and cut the textile belt, thereby realizing the reciprocating cutting of the textile belt.

[0013] (2) When the present invention cuts the textile belt with an ultrasonic cutter, the textile belt is continuously discharged by the discharge component and the extrusion conveyor roller is in a state of extrusion on the textile belt. Therefore, the textile belt between the discharge component and the extrusion conveyor roller is in a relaxed state and will not be extruded by the lifting rod. The lifting rod will be driven to rise and extrude the textile belt by the pull of the compression spring on the bottom end of the positioning rod, keeping the textile belt in a tensioned state without stopping the discharge component, thus improving the convenience of cutting.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a wear-resistant textile belt cutting device includes a work frame 1. A conveyor belt 2 is installed at one end of the work frame 1. A rotating rod 3 is rotatably installed in the middle of the work frame 1 via a bearing. A compression conveying roller 4 is fixedly installed in the middle of the rotating rod 3. The compression conveying roller 4 is used to compress and convey the textile belt. A motor 5 is fixedly installed on one side of the work frame 1 corresponding to the position of the rotating rod 3. The output end of the motor 5 passes through the work frame 1 and is fixedly connected to one end of the rotating rod 3. Limiting frames 6 are symmetrically fixedly installed at the end of the work frame 1 away from the conveyor belt 2. A blade holder 7 is slidably installed between the two limiting frames 6. An ultrasonic cutter 8 is fixedly installed at the bottom of the blade holder 7.

[0021] like Figures 1 to 4 As shown, cams 9 are symmetrically fixed at both ends of the rotating rod 3. A first sliding hole 10 is symmetrically opened in the middle of the work frame 1 corresponding to the position of the cam 9. A first sliding rod 11 is slidably installed inside the first sliding hole 10. A connecting rod 12 is rotatably installed at the bottom of the first sliding rod 11 through a shaft pin. The end of the connecting rod 12 away from the first sliding rod 11 is rotatably connected to one side of the tool holder 7 through a shaft pin.

[0022] When the extrusion conveyor roller 4 rotates once, the cam 9 will press the top of the first slide rod 11, causing the first slide rod 11 to descend. At this time, the blade holder 7 will slide down between the two limit frames 6 through the connection of the connecting rod 12, and the ultrasonic cutter 8 will cut the textile belt.

[0023] like Figures 1 to 4 As shown, the protrusion of the cam 9 is circular, and the center of the protrusion of the cam 9 coincides with the central axis of the rotating rod 3.

[0024] This operation will keep the cam 9 pressing the first slide bar 11 for a period of time, thereby meeting the time requirement for the ultrasonic cutter 8 to cut the textile belt.

[0025] like Figures 1 to 4As shown, the tool holder 7 has symmetrical second sliding holes 13 at both ends. The work frame 1 has a second sliding rod 14 fixedly installed at the position corresponding to the second sliding hole 13. The second sliding rod 14 is slidably connected to the second sliding hole 13. A return spring 15 is sleeved on the outer side of the bottom end of the second sliding rod 14. One end of the return spring 15 is fixedly connected to the tool holder 7, and the other end of the return spring 15 is fixedly connected to the work frame 1.

[0026] After the cam 9 rotates and cancels the compression of the first slide bar 11, the compression conveyor roller 4 will compress the textile belt and then convey it. The return spring 15 lifts the knife holder 7 to raise the ultrasonic cutter 8. At the same time, the connecting rod 12 will drive the first slide bar 11 to rise, thereby resetting the ultrasonic cutter 8 and the first slide bar 11.

[0027] like Figures 1 to 4 As shown, the work frame 1 has symmetrically arranged positioning holes 16 in the middle of the work frame near the side of the extrusion conveyor roller 4. Positioning rods 17 are slidably installed inside the positioning holes 16. Lifting rods 18 are fixedly installed on the top of the two positioning rods 17. Extrusion springs 19 are sleeved on the outer side of the bottom end of the positioning rods 17. One end of the extrusion spring 19 is fixedly connected to the bottom end of the positioning rod 17, and the other end of the extrusion spring 19 is fixedly connected to the work frame 1.

[0028] The ultrasonic cutter 8 will cut the textile belt. At this time, since the discharge component continuously discharges the textile belt and the extrusion conveyor roller 4 is in a state of extrusion, the textile belt between the discharge component and the extrusion conveyor roller 4 is in a relaxed state and will not be extruded by the lifting rod 18. By the extrusion spring 19 pulling the bottom of the positioning rod 17, the lifting rod 18 will be driven to rise and extrude the textile belt, keeping the textile belt continuously in the tension device. There is no need to stop the discharge component, which improves the convenience of cutting.

[0029] like Figures 1 to 4 As shown, the work frame 1 is fixedly installed at equal intervals at one end near the conveyor belt 2 with fixing rods 20 for limiting the horizontal position of the textile belt.

[0030] The horizontal position of the textile belt can be limited by the fixing rod 20.

[0031] This utility model provides a wear-resistant textile tape cutting device, the specific working principle of which is as follows:

[0032] When the device is in use, the textile belt is discharged through the discharge assembly. The operation of motor 5 drives the rotating rod 3 to rotate, which in turn drives the extrusion conveyor roller 4 to extrude and convey the textile belt. When the extrusion conveyor roller 4 rotates once, cam 9 will extrude and press the top of the first slide rod 11, causing the first slide rod 11 to descend. At this time, the connecting rod 12 will drive the cutter holder 7 to slide and descend between the two limit frames 6. Since the protrusion of cam 9 is circular, and the center of the protrusion of cam 9 coincides with the central axis of rotating rod 3, cam 9 will continue to extrude and press the first slide rod 11 for a period of time. The ultrasonic cutter 8 will then cut the textile belt. At this time, due to the continuous extrusion of the discharge assembly... The textile belt is discharged, and the extrusion conveyor roller 4 is in a state of extrusion on the textile belt. Therefore, the textile belt between the discharge component and the extrusion conveyor roller 4 is in a relaxed state and will not be extruded by the lifting rod 18. The lifting rod 18 will be driven to rise and extrude the textile belt by the pull of the positioning rod 17 by the extrusion spring 19, keeping the textile belt in the tension device. After the cam 9 rotates to cancel the extrusion of the first slide rod 11, the extrusion conveyor roller 4 will extrude the textile belt and continue to convey it. The ultrasonic cutter 8 is raised by the lifting of the knife holder 7 by the return spring 15. At the same time, the first slide rod 11 will be raised by the connection of the connecting rod 12, realizing the reciprocating cutting of the textile belt.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
