Description

Technical Field

[0001] This utility model relates to the field of edge sealing technology, specifically a circular edge sealing packaging machine. Background Technology

[0002] Packaging machines are a type of machine that packages products to protect and enhance their appearance. Circular saws, due to the ease with which their circular blades can be damaged or cause injury during transportation or handling, require edge sealing treatment at the blade edges.

[0003] For example, Chinese patent CN215922761U discloses a circular saw edge-sealing packaging machine, including an edge-sealing table. A servo motor is installed on the inner bottom wall of the edge-sealing table, and a placement tray is fixedly connected to the output end of the servo motor. The saw body is placed on the upper surface of the placement tray, and an edge-sealing seat is slidably connected to the upper surface of the edge-sealing table. A control panel is installed on the upper surface of the edge-sealing seat. This circular saw edge-sealing packaging machine, by incorporating a servo motor, placement tray, edge-sealing seat, electric push rod, conical extrusion block, hydraulic rod, cutting blade, and control panel, facilitates the pressing of the edge-sealing strip onto the blade edge of the circular saw by the conical extrusion block. The control panel automatically calculates the required sealing time based on the circumference of the blade and the rotation speed of the servo motor using a formula. The edge-sealing strip is then cut by the hydraulic rod and the cutting blade. The conical extrusion block presses the edge-sealing strip, improving the edge-sealing effect of the circular saw and preventing easy injury to workers, thus enhancing the safety of the machine.

[0004] However, in practical applications, existing circular saw edge banding equipment mainly uses a threaded rod that engages with the inner hole of the circular saw to drive the saw to rotate and complete the edge banding operation. However, this equipment has a significant drawback: the diameter of the threaded rod is fixed. Since circular saws come in various models and have different inner hole diameters in actual production and application, when this equipment is used to process circular saws with different inner hole diameters, a loose fit occurs. When the inner hole diameter of the circular saw is larger than the diameter of the threaded rod, a gap exists between them. During the rotation of the circular saw, it is very easy for the saw to shift. This shift not only seriously affects the positional accuracy of the edge banding, causing the edge banding strip to not accurately fit the saw edge, resulting in uneven edge banding, incomplete sealing, and other problems, thus reducing the edge banding effect; it may also cause uneven stress between the edge banding strip and the saw during the edge banding process, further affecting the edge banding quality, and may even cause additional wear on related components of the edge banding equipment, shortening the equipment's service life and increasing production costs. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a circular saw edge-sealing packaging machine. This technical solution solves the problems of existing circular saw edge-sealing equipment mentioned in the background section. This equipment primarily uses a threaded rod that engages with the inner hole of the circular saw to drive its rotation, thereby completing the edge-sealing operation. However, this equipment has a significant drawback: the diameter of the threaded rod is fixed. Since circular saws come in various models and have different inner hole diameters in actual production and application, when this equipment is used to process circular saws with different inner hole diameters, a loose fit occurs. When the inner hole diameter of the circular saw is larger than the diameter of the threaded rod, a gap exists between them. During the rotation of the circular saw, it is prone to misalignment. This misalignment not only severely affects the positional accuracy of the edge sealing, causing the edge-sealing strip to not accurately adhere to the saw edge, resulting in uneven sealing, incomplete sealing, and reduced sealing effect; it may also cause uneven stress between the edge-sealing strip and the saw during the sealing process, further affecting the sealing quality, and may even cause additional wear on related components of the edge-sealing equipment, shortening the equipment's service life and increasing production costs.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

The bottom end of the rotating shaft extends to the bottom of the worktable and is connected to a drive unit. A coaxial support plate is fixedly connected to the top of the rotating shaft. A bidirectional lead screw is rotatably connected to the top center of the support plate. Several vertical rods arranged in a circular array around the bidirectional lead screw are fixedly connected to the top of the support plate. A top plate is fixedly connected to the top of each vertical rod. Two lifting seats are threaded onto the bidirectional lead screw. The two lifting seats are respectively connected to the forward thread section and the reverse thread section of the bidirectional lead screw. The lifting seats are also slidably connected to each vertical rod. Four arc-shaped support plates arranged in a circular array around the bidirectional lead screw are arranged above the support plate. Push-pull rods are hinged between the two lifting seats and each arc-shaped support plate. The top end of the bidirectional lead screw extends to the top plate and is fixedly connected to a first knob.

[0014] Compared with the prior art, this utility model provides a circular knife saw edge sealing packaging machine, which has the following beneficial effects:

[0015] 1. This utility model, by setting four arc-shaped support plates arranged in a circular array around a bidirectional lead screw, and in conjunction with a lifting seat and push-pull rod driven by the bidirectional lead screw, allows for flexible adjustment of the opening range of the arc-shaped support plates, thereby adapting to circular saws with different inner hole diameters. This effectively solves the problem of easy deviation of the saw during rotation caused by the fixed diameter of the threaded rod in existing equipment, ensuring that the saw is stable and does not shake during the edge sealing process, significantly improving the edge sealing position accuracy and edge sealing effect, while avoiding additional wear caused by deviation, extending the service life of the equipment, and reducing production costs.

[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0024] Example 1

[0025] Please refer to Figures 1 to 5As shown, a circular saw-sealing packaging machine includes a worktable 1. A rotating shaft 2 is rotatably connected to the top of the worktable 1 near the left side. The bottom end of the rotating shaft 2 extends to the bottom of the worktable 1 and is connected to a drive unit 3. A support plate 4 is coaxially fixedly connected to the top of the rotating shaft 2. A bidirectional lead screw 5 is rotatably connected to the top center of the support plate 4. Several vertical rods 6 are fixedly connected to the top of the support plate 4 in a circular array centered on the bidirectional lead screw 5. A top plate 7 is fixedly connected to the top of each vertical rod 6. The upper threaded connection has two lifting seats 8, which are respectively connected to the forward thread section and the reverse thread section of the bidirectional lead screw 5. The lifting seats 8 are also slidably connected to each vertical rod 6. Four arc-shaped support plates 9 are arranged in a ring array with the bidirectional lead screw 5 as the center above the support plate 4. Push-pull rods 10 are hinged between the two lifting seats 8 and each arc-shaped support plate 9. The top end of the bidirectional lead screw 5 extends to the top plate 7 and is fixedly connected to the first knob 11. A clamping component is provided on the outside of each arc-shaped support plate 9 near the bottom.

[0026] Those skilled in the art will understand that rotating the first knob 11 causes the bidirectional lead screw 5 to rotate. Since the two lifting seats 8 are respectively connected to the forward and reverse threaded sections of the bidirectional lead screw 5, and the lifting seats 8 are slidably engaged with the vertical rod 6, the two lifting seats 8 move up and down synchronously in opposite directions along the vertical rod 6. The lifting seats 8 push the four arc-shaped support plates 9 to open or retract around the bidirectional lead screw 5 via the push-pull rod 10, thereby adapting to circular saws with different inner diameters.

[0027] It enables centering support for saw blades with different inner hole sizes, solving the problems of poor adaptability and easy deviation of traditional fixed diameter threaded rods, and improving edge sealing stability.

[0028] Example 2

[0029] Furthermore, the clamping assembly includes a groove 12 formed on the outside of the arc-shaped support plate 9 near the bottom. A vertically arranged threaded rod 13 is rotatably connected inside the groove 12. The top end of the threaded rod 13 extends to the top of the arc-shaped support plate 9 and is fixedly connected to a second knob 14. A matching sliding sleeve 15 is threaded onto the threaded rod 13. The sliding sleeve 15 is slidably disposed inside the groove 12. The groove 12 is a square groove, and the sliding sleeve 15 is a square structure that matches the square groove. An arc-shaped pressure plate 16 is fixedly connected to the outside of the sliding sleeve 15.

[0030] Those skilled in the art will understand that rotating the second knob 14 causes the threaded rod 13 to rotate. Since the sliding sleeve 15 has a square structure and slides in conjunction with the square sliding groove 12, the sliding sleeve 15 moves vertically up and down along the sliding groove 12, thereby causing the arc-shaped pressure plate 16 to press or release the circular saw.

[0031] The lifting and lowering of the arc-shaped pressure plate 16 enables the clamping of saw blades of different thicknesses. Combined with the square structure anti-rotation design, it ensures that the clamping process is stable and does not deviate, thus enhancing the positioning accuracy during edge sealing.

[0032] Example 3

[0033] Furthermore, the outer rings of the first knob 11 and the second knob 14 are both provided with anti-slip textures, the top of the support plate 4 is provided with a first anti-slip pad 17, and the bottom of the arc-shaped pressure plate 16 is fixedly connected with a second anti-slip pad 18.

[0034] Those skilled in the art will understand that the anti-slip texture of the first knob 11 and the second knob 14 improves the ease of operation, the first anti-slip pad 17 increases the friction between the saw and the support plate 4, and the second anti-slip pad 18 enhances the clamping force between the arc-shaped pressure plate 16 and the saw.

[0035] To prevent slippage during operation, further improve the stability of the saw rotation, reduce deviation caused by insufficient friction, and ensure the quality of edge banding.

[0036] Example 4

[0037] Furthermore, support legs 19 are fixedly connected to the four corners of the bottom of the workbench 1, and anti-slip pads 20 are provided on the bottom of the support legs 19.

[0038] Those skilled in the art will understand that the support leg 19 supports the workbench 1, and the anti-slip foot pad 20 increases the friction between the equipment and the ground.

[0039] Ensure the equipment is placed stably to prevent shaking during the edge sealing process from affecting the positioning accuracy of the saw and improve operational safety.

[0040] Example 5

[0041] Furthermore, the drive unit 3 includes a motor 302 fixedly connected to the bottom of the workbench 1, the bottom end of the rotating shaft 2 extends to the bottom of the workbench 1 and is fixedly connected to a worm gear 301, the output end of the motor 302 is fixedly connected to a worm 303 that meshes with the worm gear 301, the motor 302 is a bidirectional drive motor that can drive the worm 303 to rotate in both directions.

[0042] Those skilled in the art will understand that the motor 302 drives the worm 303 to rotate in both directions, and through the meshing transmission between the worm 303 and the worm wheel 301, the rotating shaft 2 drives the support plate 4 and the saw to rotate synchronously.

[0043] It achieves stable rotation of the saw blade, and with the bidirectional drive function, it meets the forward and reverse rotation requirements during the edge banding process, improving the continuity and efficiency of edge banding.

[0044] Example 6

[0045] Furthermore, the edge sealing mechanism body 22 is connected to the top of the workbench 1 near the right side via a moving mechanism 21.

[0046] Those skilled in the art will understand that the edge banding mechanism body 22 is mounted on the right side of the workbench 1 via the moving mechanism 21, and its relative position to the saw can be adjusted with the moving mechanism 21.

[0047] It allows for easy adjustment of the edge banding mechanism position according to the saw size, ensuring that the edge banding strip precisely fits the saw edge and improving edge banding flexibility.

[0048] In addition, the edge banding mechanism body 22 is existing technology in the prior art document, so the edge banding principle will not be described in detail here.

[0049] Example 7

[0050] Furthermore, the moving mechanism 21 includes a mounting groove on the top of the workbench 1 near the right side. A horizontally arranged lead screw 2101 is rotatably connected in the mounting groove. A guide rod 2102 parallel to the lead screw 2101 is also fixedly connected in the mounting groove. A moving seat 2103 is threaded onto the lead screw 2101. The moving seat 2103 is slidably connected to the guide rod 2102. The edge sealing mechanism body 22 is fixedly connected to the top of the moving seat 2103. One end of the lead screw 2101 extends outside the workbench 1 and is fixedly connected to a crank 2104.

[0051] Those skilled in the art will understand that turning the crank 2104 causes the lead screw 2101 to rotate, and the moving seat 2103, due to its sliding fit with the guide rod 2102 and its threaded connection with the lead screw 2101, moves horizontally along the guide rod 2102, thereby causing the edge sealing mechanism body 22 to adjust its position.

[0052] It achieves precise positioning of the edge banding mechanism body 22, adapts to the edge banding needs of saws with different diameters, and is simple to operate and has high adjustment accuracy.

[0053] The working principle and usage procedure of this device are as follows: Place the circular saw on the first anti-slip pad 17 on top of the support plate 4. Rotate the first knob 11 to rotate the bidirectional lead screw 5, which drives the two lifting seats 8 to rise and fall in the opposite direction along the vertical rod 6. The push-pull rod 10 pushes the four arc-shaped support plates 9 to open and fit against the inner wall of the saw hole. Rotate the second knob 14 on each arc-shaped support plate 9 to rotate the threaded rod 13. The square sliding sleeve 15 descends along the square sliding groove 12, which drives the second anti-slip pad 18 at the bottom of the arc-shaped pressure plate 16 to press the upper surface of the saw. Start the motor 302, which drives the rotating shaft 2 to rotate the support plate 4 and the saw through the worm gear 303 and worm wheel 301. Rotate the crank 2104 of the moving mechanism 21. The lead screw 2101 drives the moving seat 2103 to move along the guide rod 2102. Adjust the edge sealing mechanism body 22 to the edge of the saw for edge sealing. After the operation is completed, operate the knobs in the opposite direction to release the saw and turn off the motor 302.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
