Description
Technical Field
[0001] This utility model relates to the technical field of longitudinal and transverse cutting devices, specifically to a longitudinal and transverse cutting device for a sewing machine table. Background Technology
[0002] Longitudinal and transverse cutting devices have wide applications in many fields. For example, in furniture manufacturing, they are used for cutting, slicing, and grooving furniture boards; in building decoration, they are used for making wooden doors, windows, stairs, flooring, etc.; in the packaging industry, they are used for cutting packaging materials such as cartons and wooden crates; in hardware processing, they are used for cutting metal materials and processing parts; and during the production process of sewing machines, the table part needs to be processed using longitudinal and transverse cutting devices.
[0003] However, the existing longitudinal and transverse cutting devices on the market are mainly used for cutting materials with low strength and flexibility, such as cardboard and plastic sheets. When cutting wood on the sewing machine table, it is not easy to clamp and position it. The cutting angle needs to be found manually, and it cannot directly cut the required length or width of the board. The cutting position needs to be adjusted manually, and it needs to be cut four times to get a board, which is very troublesome and inconvenient. Utility Model Content

[0027] A longitudinal and transverse cutting device for a sewing machine table, such as Figure 1 , 2 As shown, it includes a base 1, a bracket 2, an adjustable cutting structure, a plate fixing structure, and a feeding structure.
[0028] The base 1 is a square platform, and the support 2 is erected and fixed to the right side of the base 1. The support 2 is as follows: Figure 5 As shown, the plate is L-shaped, and a fixed electric saw wheel 11 (with its own motor) is installed on the top of the left side wall. A square through hole is reserved on the front side of the plate.
[0029] Adjustable distance cutting structure such as Figure 3 As shown, the structure is located on the left side of the base 1 and includes support legs 3, limiting slide rods 4, adjusting motor 6, adjusting screw 7, transmission rod 9, moving platform 5, and moving electric saw wheel 10. Two pairs of support legs 3 are vertically arranged and fixed to the base 1 (forming a square, with each pair located at one of the four corners of the square). Two limiting slide rods 4 are arranged horizontally to the left and right, with their ends fixed to the tops of the support legs 3. The moving platform 5 is movably fitted onto the two limiting slide rods 4 on its front and rear sides, and the top of the right side wall is correspondingly fixed to the electric saw wheel 10. The movable electric saw wheel 10 and the adjustable motor 6 are fixed on the left support leg 3 (between the two support legs 3) by a motor bracket. The adjustable screw 7 is arranged parallel to the limiting slide bar 4, and one end is connected to the drive shaft of the adjustable motor 6. The other end is rotatably set on the bearing plate 8 fixed between the two support legs 3 on the right. The bottom of the transmission rod 9 is threaded onto the adjustable screw 7, and the top is connected and fixed to the bottom of the moving table 5. After the adjustable motor 6 is started, the moving table 5 drives the movable electric saw wheel 10 to move left and right along the limiting slide bar 4.
[0030] Board fixing structure such as Figure 4 As shown, the structure includes clamping plates 12, limiting posts 16, clamping motors 14, and clamping screws 15. A pair of clamping plates 12 are arranged vertically. The top of the limiting post 16 is fixed to the front end of the upper clamping plate, and the front end of the lower clamping plate is movably sleeved on the limiting post 16. The top of the clamping screw 15 is rotatably disposed at the rear end of the upper clamping plate and connected to the drive shaft of the clamping motor 14 fixed above the upper clamping plate. The rear end of the lower clamping plate is threaded onto the clamping screw 15. Each clamping surface of the clamping plates 12 is provided with an anti-slip pad 18. A pair of plate fixing structures are mirror-arranged left and right between the bracket and the adjustable-distance cutting structure. The right ends of two pairs of sliding rods 17 are respectively sleeved and fixed to the front and rear ends of each clamping plate 12 on the right side of the plate fixing structure, and the left ends are respectively sleeved and fixed with limiting caps 13 (to prevent the plate fixing structure from slipping). The front and rear ends of each clamping plate 12 on the left side of the plate fixing structure are movably sleeved on the two pairs of sliding rods 17 (when not clamped, they can be manually slid left and right).
[0031] Feeding structure such as Figure 5As shown, the system includes a feeding motor 19, a feeding screw 20, a support slide rail 22, and a positioning sleeve 21. The support slide rail 22 is a U-shaped rod (with a square cross-section) with its opening facing upwards. Both ends are connected and fixed to the front and rear ends of the lower clamping plate of the right-side plate fixing structure, respectively. The crossbar section is slidably sleeved in the square through hole of the bracket 2 (supporting the plate fixing structure by sleeved in the square through hole). The feeding motor 19 is fixed to the left side of the rear end of the support slide rail 22 by a motor bracket. The rear end of the feeding screw 20 is connected to the drive shaft of the feeding motor 19, and the front end is rotatably set on the bearing seat 23 formed on the support slide rail 22. The positioning sleeve 21 is threaded onto the feeding screw 20 and is connected and fixed together with the bracket 2. When the feeding motor 19 is started, the plate fixing structure and the fixed plate move at a constant speed in the front and rear directions.
[0032] Each motor is a bidirectional motor, and the usage and installation methods of each saw wheel and motor are all existing mature technologies that are familiar to the general public.
[0033] In the specific implementation of this embodiment:
[0034] Start the feeding motor 19 to move the plate fixing structure to the front position. Place the plate to be cut between the upper and lower clamping plates 12 on the front side of the plate fixing structure, and arrange the two plate fixing structures on the left and right sides of the plate respectively (the distance between the outer sides of the two plate fixing structures is less than the width to be cut). Turn on the clamping motor 14 (the two clamping motors 14 are synchronized to avoid damage to the slide rod 17) to firmly fix the plate on the plate fixing structure. Turn on the pitch adjustment motor 6 to adjust the position of the moving table 5 so that the distance between the moving electric saw wheel 10 and the fixed electric saw wheel 11 is equal to the width to be cut. Finally, turn on the feeding motor 19 again. The plate fixing structure and the fixed plate move at a uniform speed in the front and back direction, and the plate is cut from both sides by the moving electric saw wheel 10 and the fixed electric saw wheel 11 at the same time.
[0035] Remove the board, flip it 90°, and repeat the above steps (changing the cutting width to another width) to obtain a sewing machine table.
[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
