Description

Technical Field

[0001] This utility model belongs to the field of corrective strap processing technology, and relates to a pneumatic cutting machine for corrective straps. Background Technology

[0002] Orthopedic braces are a type of medical bandage device that uses physical external force to apply continuous pressure or traction to specific parts of the body to achieve anatomical correction, functional restoration, or posture improvement. The processing of orthopedic braces includes steps such as cutting, sewing, and overlocking, and a cutting machine is used during the cutting process.

[0003] A stamping and cutting die disclosed in Chinese patent CN222343969U has threaded rods threaded to one side of two support plates. A knob is fixedly connected to one end of each threaded rod, and a clamping plate is fixedly connected to the end of each threaded rod away from the knob. A limiting baffle is provided on one side of each clamping plate. Before stamping and cutting, the distance between the limiting baffle and the lower die base is adjusted to a suitable level according to the required length of the sheet material to be cut. The two knobs are rotated to clamp the limiting baffle using the two threaded rods and the clamping plate. The sheet material is then placed on an L-shaped positioning plate, with one side of the material adhering to the side wall of the L-shaped positioning plate. The material is then pushed to move, thereby pushing it into the positioning groove. The width of the material is equal to the width of the positioning groove, ensuring that one end of the material is in contact with one side of the limiting baffle.

[0004] When using this stamping and cutting die, the material is pushed directly below the upper die holder so that the cutting blade can perform the cutting operation. If the material to be cut is flexible, the operator needs to move the material to the positioning slot and lay it out, which is not very convenient to use.

[0005] To solve the above problems, this utility model proposes a pneumatic cutting machine for correcting straps. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes a pneumatic cutting machine for correcting straps.

[0008] A connecting plate is fixedly installed directly above the workbench. An L-shaped sliding plate is horizontally slidable on the top of the connecting plate via a first spring. A positioning seat is fixedly connected to one end of the sliding plate.

[0009] The end of the connecting seat away from the pressure block is provided with an abutment. When the cylinder drives the connecting seat to move downward, the abutment drives the positioning seat to move directly below the cutter.

[0010] Furthermore, a base plate is fixedly connected to the top of the workbench, and two support columns are fixedly connected to each of the two sides of the top surface of the base plate. The top of the four support columns is fixedly connected to the same top plate, and the cylinder is fixedly connected to the top of the top plate. The telescopic end of the cylinder slides through the top plate.

[0011] Furthermore, a collection box is fixedly connected to the top of the base plate, a connecting plate is fixedly connected to the top of the collection box, a through hole is opened in the middle of the connecting plate, the through hole corresponds vertically to the cutter, and a drawer is horizontally slidably arranged inside the collection box.

[0012] Furthermore, a push block is fixedly connected to the bottom of the connecting seat, the push block corresponds vertically to the through hole, and the cutter is fixedly connected to the bottom of the push block;

[0013] The pressure block is L-shaped and consists of a horizontal section and a vertical section from top to bottom. The vertical section of the pressure block slides vertically through the connecting seat. The top end of the second spring is fixedly connected to the bottom surface of the horizontal section of the pressure block, and the bottom end of the second spring is fixedly connected to the top of the connecting seat.

[0014] Furthermore, a protective cover is fixedly connected to the top of the connecting plate, and a groove is provided at the bottom of the protective cover.

[0015] The telescopic end of the cylinder slides vertically through the top surface of the protective cover, and the connecting seat, push block, and pressure block are all located inside the protective cover.

[0016] Furthermore, the slide plate is composed of a vertical section and a horizontal section from top to bottom. The horizontal section of the slide plate is slidably connected to the top surface of the connecting plate, and the positioning seat is fixedly connected to the end of the horizontal section of the slide plate.

[0017] One end of the first spring is fixedly connected to one side of the protective cover, and the other end of the first spring is fixedly connected to one side of the vertical section of the slide plate;

[0018] The positioning seat has a discharge groove at one end near the slide plate. The push block is adapted to the shape of the discharge groove and is slidably disposed inside the discharge groove. The cutter slides and engages with the inner wall of the discharge groove.

[0019] Furthermore, the abutment includes a roller, and a connecting rod is fixedly connected to one end of the connecting seat.

[0020] A protrusion is fixedly connected to the corner of the inner wall of the skateboard. The top surface of the protrusion is an inclined surface. The top surface of the protrusion gradually slopes upward from one end near the protective cover to the other end. The side of the protrusion near the protective cover is a vertical surface. The roller abuts against both the inclined surface and the vertical surface of the protrusion.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. This pneumatic cutting machine for straightening straps is equipped with a positioning seat, which is fixedly connected to one end of the slide plate. In use, the straightening strap is placed inside the positioning seat, so that the cutting end of the straightening strap is located at the discharge groove. Then, the cylinder pushes the connecting seat downward, causing the cutter to move downward. The abutment will first drive the discharge groove on the positioning seat to move directly below the cutter. Then, the cutter cuts the straightening strap, so that the straightening strap can be automatically moved to the cutting position while the cutter moves downward. This makes it easy to place the straightening strap outside the protective cover and facilitates operation.

[0023] 2. The pneumatic cutting machine for corrective straps is equipped with a first spring. The two ends of the first spring are fixedly connected to the slide plate and the protective cover, respectively. When the cutter moves downward to cut the corrective strap, the abutment will push the slide plate to move and stretch the first spring. When the cutter moves upward, the first spring will pull the slide plate to move, so that the positioning seat moves outward from the protective cover, making it easy to remove the cut corrective strap and reposition it. It is convenient to use.

[0024] 3. The pneumatic cutting machine for straightening straps is equipped with a pressure block, which is connected to the connecting seat via a second spring. When the connecting seat drives the cutter to move downward to cut the straightening strap, the pressure block will first contact the straightening strap as it moves downward. Then, the connecting seat will slide outside the pressure block and stretch the second spring. The second spring exerts a downward force on the pressure block, causing the pressure block to press against the straightening strap and compress it. This makes the straightening strap more stable during subsequent cutting and reduces the possibility of inaccurate cutting due to displacement. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] like Figures 1-7 As shown, the technical solution adopted by this utility model is as follows: A pneumatic cutting machine for correcting straps includes a worktable 1, a cylinder 3 is fixedly installed directly above the worktable 1, and an L-shaped connecting seat 19 is fixedly connected to the bottom of the telescopic end of the cylinder 3. The cylinder 3 is vertically arranged, so that the telescopic end of the cylinder 3 drives the connecting seat 19 to move up and down.

[0035] A base plate 4 is fixedly connected to the top of the workbench 1. Two support columns 5 are fixedly connected to each of the two sides of the top surface of the base plate 4. The top of the four support columns 5 is fixedly connected to the same top plate 6. A cylinder 3 is fixedly connected to the top of the top plate 6, and the telescopic end of the cylinder 3 slides through the top plate 6, so that the connecting seat 19 is located below the top plate 6.

[0036] A foot pedal valve 2 is installed at the bottom of the workbench 1. The foot pedal valve 2 is connected to the air port of the cylinder 3 via an air pipe. The foot pedal valve 2 is a pneumatic component with a spring piston rod that creates airflow and exhaust through clamping. The cylinder 3 is driven by stepping on the foot pedal valve 2. This is used in punch presses, injection molding machines, and cylinder lifting platforms in auto repair shops. The connection method and working principle of the foot pedal valve 2 and cylinder 3 are existing technologies and will not be elaborated further here.

[0037] A cutter 21 is fixedly installed at the bottom of the connector 19.

[0038] A push block 20 is fixedly connected to the bottom of the connecting base 19, and a cutter 21 is fixedly connected to the bottom of the push block 20. This causes the connecting base 19 to drive the push block 20 and the cutter 21 to move downwards.

[0039] One end of the connecting seat 19 is vertically slidably connected to the pressure block 17 via the second spring 18. The connecting seat 19 drives the pressure block 17 to move up and down, and at the same time, the pressure block 17 can also slide vertically on the connecting seat 19.

[0040] The pressure block 17 is L-shaped. From top to bottom, the pressure block 17 consists of a horizontal section and a vertical section, with the vertical section sliding vertically through the connecting seat 19. This ensures that the horizontal section of the pressure block 17 is positioned above the connecting seat 19.

[0041] The top end of the second spring 18 is fixedly connected to the bottom surface of the horizontal section of the pressure block 17, and the bottom end of the second spring 18 is fixedly connected to the top of the connecting seat 19. In the initial state, the second spring 18 pulls the pressure block 17 downward, so that the bottom surface of the pressure block 17 is below the cutter 21.

[0042] A connecting plate 9 is fixedly installed on the top of the workbench 1.

[0043] A collection box 11 is fixedly connected to the top of the base plate 4, and a connecting plate 9 is fixedly connected to the top of the collection box 11. The connecting plate 9 is located below the pressure block 17, allowing the connecting seat 19 to move up and down between the top plate 6 and the connecting plate 9.

[0044] A through hole is provided in the middle of the connecting plate 9, and the push block 20 and the cutter 21 are vertically aligned with the through hole. The cutter 21 cuts the corrective strap at the through hole. A drawer 10 is horizontally slidable inside the collection box 11. The cut corrective strap falls into the drawer 10 through the through hole, thereby collecting the waste.

[0045] A protective cover 7 is fixedly connected to the top of the connecting plate 9. The telescopic end of the cylinder 3 slides vertically through the top surface of the protective cover 7, and the connecting seat 19, push block 20, and pressure block 17 are all located inside the protective cover 7. This allows the cutter 21 to perform cutting work inside the protective cover 7, increasing safety through the protective cover 7.

[0046] An L-shaped slide plate 13 is horizontally slidable on the top of the connecting plate 9 via a first spring 12, and a positioning seat 8 is fixedly connected to one end of the slide plate 13.

[0047] The bottom of the protective cover 7 is provided with a sliding groove, through which both the sliding plate 13 and the positioning seat 8 can slide horizontally. The positioning seat 8 slides in cooperation with the inner wall of the sliding groove. The positioning seat 8 can be moved into the interior of the sliding groove by moving the sliding plate 13.

[0048] The slide plate 13 consists of a vertical section and a horizontal section from top to bottom. The horizontal section of the slide plate 13 is slidably connected to the top surface of the connecting plate 9, and the positioning seat 8 is fixedly connected to the end of the horizontal section of the slide plate 13.

[0049] One end of the first spring 12 is fixedly connected to one side of the protective cover 7, and the other end of the first spring 12 is fixedly connected to one side of the vertical section of the slide plate 13. In the initial state, the first spring 12 pulls the slide plate 13, so that the positioning seat 8 is located outside the protective cover 7.

[0050] The positioning seat 8 has a discharge groove 22 at one end near the slide plate 13, and the push block 20 is adapted to the shape of the discharge groove 22. The push block 20 is slidably disposed inside the discharge groove 22, and the cutter 21 slides in cooperation with the inner wall of the discharge groove 22. The corrective strap is cut by the cooperation between the cutter 21 and the inner wall of the discharge groove 22, and at the same time the push block 20 moves downward to push the corrective strap downward.

[0051] An abutment is provided at the end of the connecting seat 19 away from the pressure block 17. When the cylinder 3 drives the connecting seat 19 to move downward, the abutment drives the positioning seat 8 to move directly below the cutter 21.

[0052] The abutment includes a roller 14. A connecting rod 15 is fixedly connected to one end of the connecting seat 19. The connecting rod 15 slides vertically through the protective cover 7. A groove is formed at the end of the connecting rod 15 away from the connecting seat 19, and the roller 14 is rotatably connected inside the groove. This causes the connecting seat 19 to drive the connecting rod 15 and the roller 14 to move up and down.

[0053] A protrusion 16 is fixedly connected to the corner of the inner wall of the slide plate 13. The top surface of the protrusion 16 is an inclined surface, which gradually slopes upward from one end near the protective cover 7 to the other end. The side of the protrusion 16 near the protective cover 7 is a vertical surface, and the roller 14 abuts against both the inclined surface and the vertical surface of the protrusion 16. When the connecting seat 19 drives the roller 14 to move, the roller 14 rolls on the inclined surface and the vertical surface of the protrusion 16, and at the same time pushes the protrusion 16 to move.

[0054] Working principle:

[0055] When in use, the staff places the corrective strap on the positioning seat 8, so that the cut end of the corrective strap is located at the discharge chute 22.

[0056] The operator steps on foot valve 2, causing the telescopic end of cylinder 3 to drive connecting seat 19, push block 20, and cutter 21 to move downwards. At the same time, it drives the second spring 18 and pressure block 17 to move downwards.

[0057] Connector 19 drives link 15 and roller 14 downwards, with roller 14 initially rolling on the inclined surface of protrusion 16. This causes roller 14 to press against protrusion 16, moving it away from the protective cover 7. Protrusion 16 then moves slide plate 13 and stretches the first spring 12.

[0058] The vertical section of the slide plate 13 is moved away from the protective cover 7, and the horizontal section of the slide plate 13 slides on the top of the connecting plate 9, causing the positioning seat 8 to slide on the top of the connecting plate 9. The positioning seat 8 is then moved inward toward the protective cover 7.

[0059] When roller 14 moves to the vertical surface on one side of protrusion 16, roller 14 can no longer push protrusion 16 to move. At this time, discharge groove 22 corresponds vertically to push block 20, and cutter 21 corresponds vertically to inner wall of discharge groove 22. At this time, discharge groove 22 is located at through hole on connecting plate 9.

[0060] The connecting seat 19 continues to move downwards, and the roller 14 moves downwards on the vertical surface of the protrusion 16. The bottom end of the pressure block 17 will first contact the corrective strap, and then the connecting seat 19 will slide outside the pressure block 17.

[0061] The connecting seat 19 drives one end of the second spring 18 to move downwards. The second spring 18 exerts a downward force on the pressure block 17, causing the pressure block 17 to press down and tighten the straightening strap. Then, the cutter 21 moves downwards to cut the straightening strap. The cut straightening strap is located in the discharge groove 22. When the pusher 20 moves into the discharge groove 22, it pushes the cut straightening strap downwards. After that, the cut straightening strap falls into the drawer 10 through the through hole.

[0062] When the worker releases the foot pedal valve 2, the telescopic end of the cylinder 3 drives the connecting seat 19, push block 20, and cutter 21 to move upward. The connecting seat 19 then drives the roller 14 to move upward on the vertical surface of the protrusion 16.

[0063] The connecting seat 19 causes one end of the second spring 18 to move upward. At this time, the second spring 18 continues to pull the pressure block 17 downward, so that the pressure block 17 continues to abut against the corrective strap. After the second spring 18 returns to its initial state, the connecting seat 19 causes the second spring 18 and the pressure block 17 to move upward together.

[0064] When roller 14 moves to the inclined surface of protrusion 16, roller 14 no longer presses against protrusion 16. At this time, the first spring 12 will pull the slide plate 13 to move, causing protrusion 16 to move closer to the protective cover 7. Protrusion 16 continues to abut against roller 14. Slide plate 13 will push positioning seat 8 to move outward of protective cover 7 until positioning seat 8 is moved to the outside of protective cover 7, making it easy to remove the corrective strap.

[0065] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
