Abstract
Description
Technical Field
[0001] This utility model relates to the field of subwoofer manufacturing technology, specifically to a leather cutting machine with a positioning device. Background Technology
[0002] Subwoofer is a common term or abbreviation. Strictly speaking, it should be: bass speaker box. In English, subwoofer means super bass, which is a bass with heat and energy. As the name suggests, the function of subwoofer is to enhance the bass band, that is, to enhance the long wave part of the audio. Because ordinary speakers have limited size, they cannot produce low-frequency sounds with longer wavelengths, so a larger subwoofer is needed to produce a warm low-frequency effect.
[0003] Subwoofers often require a wooden casing during production to house the speaker. To enhance the aesthetics, genuine leather is often applied to the surface of the wooden casing. This requires cutting the leather, which necessitates the use of a leather cutting machine. Traditional leather cutting machines often place the leather directly inside for cutting. Due to the lack of a positioning device, the leather moves with the cutting blade during the cutting process, leading to misalignment and waste of leather, thus failing to meet the cutting requirements.

[0029] Example
[0030] The leather cutting machine with positioning device provided in this embodiment, such as Figures 1-7 As shown, the system includes a base 1, with mounting strips 2 fixedly installed on both sides of the top of the base 1. The mounting strips 2 have a receiving groove 9 inside, and a placement plate 4 is inserted inside the receiving groove 9. A mounting plate 3 is installed on the top of the mounting strips 2, and multiple leather cutting blades 15 are installed on the bottom of the mounting plate 3. Positioning mechanisms 6 are installed on the front and rear sides of the bottom of the mounting plate 3. The mounting strips 2 and receiving grooves 9 are used to receive the placement plate 4. The placement plate 4 is used to place the leather. The mounting plate 3 is used to install hydraulic rods 5. The hydraulic rods 5 are used to cut the leather placed on top of the placement plate 4. The positioning mechanisms 6 are used to squeeze and fix the leather placed on top of the placement plate 4 before cutting, so as to prevent the leather from moving with the hydraulic rods 5 after cutting and affecting subsequent cutting.
[0031] The positioning mechanism 6 includes two mounting cavities 605 located on the front and rear sides of the mounting plate 3. A connecting rod 604 is inserted inside the mounting cavity 605. The bottom of the connecting rod 604 is fixedly connected to the top of the extrusion plate 603. A spring 602 is sleeved on the outside of the connecting rod 604 and on the top of the extrusion plate 603. The top of the spring 602 contacts the bottom of the mounting plate 3. The mounting cavity 605 is used to accommodate the connecting rod 604. The connecting rod 604 is used to install the spring 602 and the extrusion plate 603. The extrusion plate 603 is used to extrude leather. The spring 602 is used to press the extrusion plate 603 downward to extrude and fix the leather.
[0032] A limiting block 601 is provided on the top of the mounting plate 3. The bottom of the limiting block 601 is fixedly connected to the top of the connecting rod 604. The limiting block 601 is used to limit the top of the connecting rod 604 and prevent the connecting rod 604 from detaching from the mounting plate 3.
[0033] A handle 7 is fixedly installed on the front side of the placement plate 4, and rollers are fixedly installed on both sides of the bottom of the placement plate 4. The handle 7 is designed to facilitate the insertion of the placement plate 4 into the interior of the mounting strip 2, and the rollers facilitate the movement of the placement plate 4, thereby facilitating the subsequent cutting of the leather on the top of the placement plate 4.
[0034] Two limiting cavities 11 are opened on both sides inside the mounting plate 3. A limiting rod 8 is inserted inside the limiting cavity 11. The bottom of the limiting rod 8 is fixedly connected to the top of the mounting strip 2. The limiting cavity 11 and the limiting rod 8 are used to limit the mounting plate 3 and increase the stability of the mounting plate 3 when it is raised or lowered.
[0035] The mounting strip 2 has an internal cavity 10, and a hydraulic rod 5 is fixedly installed inside the cavity 10. The top of the hydraulic rod 5 is fixedly connected to the bottom of the mounting plate 3. The cavity 10 is used to install the hydraulic rod 5. The positioning mechanism 6 is used to adjust the mounting plate 3 by raising and lowering it, thereby driving the hydraulic rod 5 to cut the leather placed on the top of the mounting plate 4.
[0036] Two limiting strips 12 are fixedly installed at the bottom of the mounting plate 3. The leather cutting knife 15 extends to the inside of the limiting strips 12. The setting of the limiting strips 12 facilitates the subsequent accommodation and limiting of the hydraulic rod 5.
[0037] The limiting strip 12 has a through cavity 13 inside, and a bolt 14 is inserted inside the through cavity 13. The bolt 14 passes through the inside of the leather cutting knife 15. The through cavity 13 and the bolt 14 are used to fix the hydraulic rod 5 to the limiting strip 12, and at the same time facilitate the subsequent disassembly of the leather cutting knife 15, so as to facilitate the subsequent cutting of leather into different shapes.
[0038] In use, according to the shape of the leather strip to be cut, place the hydraulic rod 5 of the required shape below the mounting plate 3 and inside the limiting strip 12. The bolt 14 passes through the through cavity 13 and passes through the limiting strip 12 and the leather cutting knife 15 respectively, and fixes the leather cutting knife 15 below the limiting strip 12. After fixing, place the leather on the top of the placement plate 4. Push the placement plate 4 under the mounting plate 3 through the handle 7. Pull the mounting plate 3 and the leather cutting knife 15 down through the hydraulic rod 5. At the same time, the extrusion plate 603, which follows the descent of the mounting plate 3, makes contact with the top of the leather in advance. At the same time, as the mounting plate 3 descends, the spring 602 is compressed to fix the leather, so as to cut the leather placed on the top of the placement plate 4. After cutting, as the mounting plate 3 rises, the extrusion plate 603 continues to extrude the leather under the compression of the spring 602. At the same time, the leather cutting knife 15 separates from the leather. After separation, push the placement plate 4 to continue to move backward through the handle 7, and continue to cut the leather placed on the top of the placement plate 4.
[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
