[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0025] like Figure 1-Figure 5 As shown, the technical solution adopted by the utility model is as follows: a sponge fixing device for a sponge cutting machine comprises a workbench 1, a slide groove is provided on the top of the workbench 1, two connecting blocks 2 are slidably arranged in the slide groove, and a driving mechanism for driving the connecting blocks 2 to slide is provided in the workbench 1.
[0026] The driving mechanism includes a bidirectional threaded rod 5, both ends of which are threadedly penetrate the connecting block 2. One end of the bidirectional threaded rod 5 is rotatably connected to the workbench 1, and the other end of the bidirectional threaded rod 5 penetrates the workbench 1 and extends to the outside of the workbench 1. A handle 4 is fixedly arranged at one end of the bidirectional threaded rod 5 located outside the workbench 1, and the handle 4 is fixedly connected to the bidirectional threaded rod 5.
[0027] The handle 4 is rotated, and the rotation of the handle 4 drives the bidirectional threaded rod 5 to rotate. The rotation of the bidirectional threaded rod 5 drives the two connecting blocks 2 to slide toward each other or away from each other.
[0028] The facing surfaces of the two connecting blocks 2 are provided with a sliding cavity 11, and a sliding block 9 is slidably arranged in the sliding cavity 11. Pressure sensors are fixedly arranged on the facing sides of the two sliding blocks 9. A magnet block 10 is fixedly arranged on the side of the sliding block 9 facing the sliding cavity 11, and an electromagnet 8 is fixedly arranged in the sliding cavity 11. The pressure sensor and the electromagnet 8 are both electrically connected to the controller.
[0029] Connecting rods 13 are rotatably arranged on both sides of the connecting block 2, and a torsion spring is sleeved on the rotating shaft between the middle of the connecting rod 13 and the side wall of the connecting block 2. One end of the torsion spring is fixedly connected to the connecting rod 13, and the other end of the torsion spring is fixedly connected to the connecting block 2. A pressing block 3 is fixedly arranged at one end of the connecting rod 13, and a protrusion 12 is fixedly arranged at the other end of the connecting rod 13. Waist-shaped grooves are opened on both sides of the connecting block 2, and the protrusion 12 is slidably arranged in the waist-shaped grooves, and the end of the protrusion 12 away from the connecting rod 13 penetrates the connecting block 2 and extends to the inside of the connecting block 2.
[0030] The two connecting blocks 2 slide towards each other, which drives the two sliding blocks 9 to slide towards each other. When the two sliding blocks 9 contact the sponge, the pressure sensor transmits the pressure signal to the controller, and the controller controls the electromagnet 8 to be energized in the forward direction. The electromagnet 8 attracts the sliding block 9, and the sliding block 9 slides in the direction close to the electromagnet 8.
[0031] When the sliding block 9 slides close to the electromagnet 8, the sliding block 9 will squeeze the protrusion 12, thereby driving the protrusion 12 to slide upward along the waist-shaped groove. When the protrusion 12 slides upward along the waist-shaped groove, the pressing block 3 will rotate downward, thereby causing the pressing blocks 3 on both sides to press and fix the sponge. The setting of the pressing block 3 improves the fixing effect of the device on the sponge, and also improves the stability of the sponge when the sponge is cut.
[0032] A fixing component is provided on the connecting block 2. The fixing component includes a limiting column 7. A "T"-shaped slot is provided on the connecting block 2, and the "T"-shaped slot is located at the bottom of the sliding cavity 11. The limiting column 7 is slidably arranged in the "T"-shaped slot. An arc block is fixedly arranged on the top of the limiting column 7, and the top of the arc block is higher than the bottom of the sliding cavity 11. A spring 6 is sleeved on the circumferential surface of the limiting column 7. The upper end of the spring 6 is fixed to the arc block, and the lower end of the spring 6 is fixedly connected to the bottom of the "T"-shaped slot. A through slot is provided at the bottom of the "T"-shaped slot, and the limiting column 7 is slidably arranged in the through slot.
[0033] The sliding block 9 will contact the arc block when sliding toward the electromagnet 8. As the sliding continues, the sliding block 9 will squeeze the arc surface of the arc block, thereby driving the arc block to slide downward. The arc block will slide downward and drive the limit column 7 to slide downward. The limit column 7 will slide downward and contact the bidirectional threaded rod 5, thereby limiting and fixing the bidirectional threaded rod 5, and then limiting the handle 4, so that the handle 4 cannot be rotated.
[0034] How it works
[0035] Place the sponge between the two connecting blocks 2, turn the handle 4, the handle 4 turns to drive the bidirectional threaded rod 5 to turn, the bidirectional threaded rod 5 turns to drive the two connecting blocks 2 to slide toward each other, the two connecting blocks 2 slide toward each other and drive the two sliding blocks 9 to slide toward each other. When the two sliding blocks 9 contact the sponge, the two sliding blocks 9 will be affected by the sponge. The pressure sensor obtains the pressure signal and transmits it to the controller, the controller controls the electromagnet 8 to conduct forward, and the electromagnet 8 attracts the sliding block 9 to slide continuously into the sliding cavity 11.
[0036] When the sliding block 9 slides toward the electromagnet 8, it will first contact the arc block. As the sliding continues, the sliding block 9 will squeeze the arc surface of the arc block, thereby driving the arc block to slide downward. The arc block slides downward and drives the limit column 7 to slide downward. The limit column 7 slides downward and contacts the bidirectional threaded rod 5, thereby limiting and fixing the bidirectional threaded rod 5, and then limiting the handle 4, so that the handle 4 cannot be rotated. At this time, the spring 6 is in a compressed state.
[0037] At the same time, when the sliding block 9 slides close to the electromagnet 8, the sliding block 9 will squeeze the protrusion 12, thereby driving the protrusion 12 to slide upward along the waist-shaped groove. When the protrusion 12 slides upward along the waist-shaped groove, the pressing block 3 will rotate downward, thereby causing the pressing blocks 3 on both sides to press and fix the sponge. The setting of the pressing block 3 improves the fixing effect of the device on the sponge, and also improves the stability of the sponge when the sponge is cut.
[0038] When the sponge cutting is completed and needs to be reset, the controller changes the current direction of the electromagnet 8, so that the electromagnet 8 and the magnet block 10 produce a repulsive force, thereby moving the sliding block 9 away from the electromagnet 8, and the sliding block 9 will slide to the side away from the electromagnet 8.
[0039] The limit post 7 will be reset under the elastic action of the spring 6, and the connecting rod 13 will be reset under the elastic action of the torsion spring. With the reset of the limit post 7, the handle 4 can continue to rotate, which is convenient for completing the next clamping work, making the device more convenient to use and having a better fixing effect.
