Description

Technical Field

[0001] This application relates to the field of sponge processing technology, and in particular to an automatic sponge cutting and rewinding device. Background Technology

[0002] In packaging, furniture manufacturing, and industrial cushioning materials, sponge is widely used as a material with softness, elasticity, and cushioning properties. Automatic cutting and winding are crucial steps in sponge processing, and their efficiency and precision directly affect product quality and production efficiency.

[0003] In existing related technologies, traditional sponge cutting and winding devices typically operate using a fixed cutting tool combined with mechanical transmission. First, a cylindrical sponge with pre-drilled holes is fitted onto a sponge mounting rod. Then, a trapezoidal screw is rotated, causing the cylindrical sponge to contact the cutting blade at the bottom. As the sponge mounting rod rotates, the cylindrical sponge begins to be cut, and the cut sponge is then wound up onto a take-up rod. For example, see the utility model patent with publication number CN205772212U, entitled "A Sponge Winding Mechanism".

[0004] Regarding the aforementioned technologies, in actual use, when placing the cylindrical sponge onto the sponge mounting rod, the entire bracket and sponge mounting rod need to be removed before installation, which is slow and reduces production efficiency. Summary of the Invention

[0005] To improve the installation efficiency of cylindrical sponges, this application provides an automatic sponge cutting and winding device.

[0006] The automatic sponge cutting and winding device provided in this application adopts the following technical solution: An automatic sponge cutting and rewinding device includes a support base and a feeding assembly. The feeding assembly includes a first support platform, a second support platform, a fixing member, and a sponge mounting rod. The first and second support platforms are both mounted on the support base. Both the first and second support platforms have mounting rod placement slots with a fan-shaped cross-section adapted to the sponge mounting rod. The first and second support platforms are fixedly connected to a fixed slide rail. The fixing member slides vertically along the fixed slide rail. There are two fixing members, one on the first support platform and the other on the second support platform. The sponge mounting rod in the mounting rod placement slot is limited and fixed by the fixing member. One end of the fixing member is provided with a tightening bolt, which is threaded onto the first or second support platform. The fixing member is detachably mounted to the fixed slide rail by the tightening bolt.

[0007] By adopting the above technical solution, when the cylindrical sponge needs to be replaced, the tightening bolts of the first and second support platforms can be loosened, and the fixing parts can be removed from the fixed slide rail, thus unlocking the two fixing parts that secure the two ends of the sponge mounting rod. Then, the sponge mounting rod is removed, and the cylindrical sponge on it is replaced. After replacement, both ends of the sponge mounting rod are placed in the mounting rod placement slots of the first and second support platforms, respectively. Finally, the sponge mounting rod is locked in place by tightening the bolts and fixing parts. This design helps improve the installation efficiency of the cylindrical sponge.

[0008] Optionally, the first support platform is fixedly connected to a first drive motor, the output shaft of the first drive motor is provided with a first gear, and one end of the sponge mounting rod is provided with a second gear, the first gear being able to mesh with the second gear.

[0009] By adopting the above technical solution, when replacing the cylindrical sponge, it is only necessary to align and mesh the second gear at one end of the sponge mounting rod with the first gear on the output shaft of the first drive motor. This allows the drive motor to rotate the sponge mounting rod around its own axis, improving the installation efficiency of the cylindrical sponge.

[0010] Optionally, the automatic sponge cutting and rewinding device further includes a cutting assembly, which includes an auxiliary roller and a cutting blade. The auxiliary roller is rotatably connected to the top of the support base, and there is a gap between the auxiliary roller and the cutting blade. The top of the support base is provided with a blade placement groove, and the side of the support base is provided with an entry hole that communicates with the blade placement groove. The blade placement groove is inclined, and the cutting blade enters the blade placement groove through the entry hole.

[0011] By employing the above technical solution, the sponge mounting rod is lowered, causing the cylindrical sponge, auxiliary roller, and cutting blade to come into contact with each other. Driven by the first drive motor, the sponge mounting rod rotates around its own axis, allowing the cutting blade to cut the cylindrical sponge.

[0012] Optionally, a take-up rod is installed on the top of the support base, and a second drive motor is fixedly connected to the support base, which causes the take-up rod to rotate around its own axis.

[0013] By adopting the above technical solution, the sponge, which has been cut by the cutting blade, can be manually fixed and pasted onto the take-up rod. Driven by the second motor, the take-up rod stretches and retracts the cut sponge, and cooperates with the rotation of the sponge mounting rod to achieve the effect of automatic cutting and winding, thereby improving production efficiency.

[0014] Optionally, the support base has a waste receiving chamber and a waste outlet, the waste outlet facing the gap between the auxiliary roller and the cutting blade, the waste outlet communicating with the waste receiving chamber, and a waste collection drawer provided in the waste receiving chamber.

[0015] By adopting the above technical solution, the cylindrical sponge cut by the cutting blade will generate waste debris. The waste debris will flow into the waste receiving chamber through the waste inlet and be collected by the waste collection drawer for subsequent processing.

[0016] Optionally, the automatic sponge cutting and winding device further includes two support columns, each with a trapezoidal lead screw inside. A third drive motor is located at the top of the support column, and the output end of the third drive motor is connected to the trapezoidal lead screw. The first support platform is threaded into the trapezoidal lead screw, and the second support platform is threaded into the trapezoidal lead screw. The two support columns slide and engage with the first support platform and the second support platform along the length of the trapezoidal lead screw, respectively.

[0017] By adopting the above technical solution, the trapezoidal lead screw has a self-locking function and can be rotated by a third drive motor, thereby causing the first and second support platforms to slide along the length of the support column. This achieves the effect of adjusting the height of the first and second support platforms, thus facilitating the installation of the sponge mounting rod.

[0018] Optionally, one end of the cutting blade is provided with a pull handle.

[0019] By adopting the above technical solution, the operator can easily place the cutting blade into the blade placement slot through the access hole by pulling out the handle.

[0020] Optionally, the blade placement slot is equipped with a blade clamping member and a clamping nut. The blade clamping member and the clamping nut are arranged in pairs, and there are multiple blade clamping members and clamping nuts. The blade clamping member is rotatably connected to the blade placement slot through the clamping nut, and the clamping nut is fixedly connected to the blade placement slot. The blade clamping member is threaded into the clamping nut. The blade clamping member is provided with a clamping head, which passes through the blade placement slot and clamps against the cutting blade.

[0021] By adopting the above technical solution, users can tighten the clamping head against the cutting blade by twisting the blade clamping component, thereby achieving the effect of fixing the cutting blade and improving safety.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. When the cylindrical sponge needs to be replaced, the tightening bolts of the first and second support platforms can be loosened, and the fasteners removed from the fixed slide rail. This unlocks the two fasteners securing the two ends of the sponge mounting rod. The cylindrical sponge on the mounting rod can then be replaced. Next, the two ends of the sponge mounting rod are placed into the mounting rod placement slots on the first and second support platforms respectively, and then the bolts and fasteners are tightened to lock the sponge mounting rod in place. This design helps improve the installation efficiency of the cylindrical sponge. 2. The cylindrical sponge cut by the cutting blade will generate waste debris. The waste debris will flow into the waste receiving chamber through the waste inlet and be collected by the waste collection drawer for subsequent processing. 3. Users can tighten the clamping head against the cutting blade by twisting the blade clamping part, thereby fixing the cutting blade and improving safety. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses an automatic sponge cutting and winding device. (Refer to...) Figure 1The automatic sponge cutting and rewinding device includes a support base 1, a cutting assembly 2, a feeding assembly 3, and a support column 4. The cutting assembly 2, the feeding assembly 3, and the support column 4 are all installed on the top of the support base 1.

[0031] Reference Figure 1 and Figure 2 The cutting assembly 21 includes an auxiliary roller 21 and a cutting blade 22. The auxiliary roller 21 is rotatably fitted to the support base 1, and its axis is set along the width direction of the winding device. A blade placement groove 201 is fixedly mounted on the support base 1, extending along the width direction of the automatic sponge cutting and winding device. The blade placement groove 201 has a U-shaped cross-section, with its opening facing the auxiliary roller 21 and inclined upwards. The blade placement groove 201 is used to mount the cutting blade 22, ensuring that the cutting edge of the blade 22 faces the auxiliary roller 21 and is inclined upwards. Furthermore, a gap is provided between the cutting blade 22 and the auxiliary roller 21 for sponge transport, so that the sponge to be cut is pressed and limited by the auxiliary roller 21 when passing through the gap and cut into strips by the cutting blade 22. The back of the cutting blade 22 installed in the blade placement groove 201 is attached to the inner wall of the blade placement groove 201 away from the groove opening to ensure the stability of the cutting blade 22.

[0032] Reference Figure 1 and Figure 2 The blade placement slot 201 is equipped with two pairs of blade clamping members 23 and clamping nuts 24. The blade clamping members 23 and clamping nuts 24 are arranged in pairs, with each pair located at one end of the blade placement slot 201. The blade clamping member 23 is a bolt, and it is rotatably connected to the blade placement slot 201 via the clamping nut 24, which is in turn fixedly connected to the blade placement slot 201. The blade clamping member 23 is threaded into the clamping nut 24 and has a clamping head that extends into the blade placement slot 201. By rotating the blade clamping member 23, the clamping head continuously presses against and adheres to the cutting blade 22 placed in the blade placement slot 201, ensuring the cutting blade 22 is securely installed inside the blade placement slot 201. This facilitates the detachable installation of the cutting blade 22 into the blade placement slot 201. The support base 111 has an access hole 202 on its side, which connects to the blade placement slot 201. The diameter of the access hole 202 is adapted to the cutting blade 22, allowing the cutting blade 22 to be inserted into the blade placement slot 201 through the access hole 202. This facilitates the replacement of the cutting blade 22 and reduces the possibility of the cutting blade 22 obstructing the replacement process. Furthermore, one end of the cutting blade 22 is equipped with a pull handle 25. After releasing the two blade clamping parts 23, the operator can lift the pull handle 25 to remove the cutting blade 22 from the blade placement slot 201 through the access hole 202 for maintenance.

[0033] Reference Figure 3 The support base 1 has a waste receiving chamber 203, and a waste collection drawer 26 is installed inside the waste receiving chamber 203. A waste outlet is provided through the support base 1, located at the bottom of the cutting blade 22. The waste outlet connects to the waste receiving chamber 203 and faces the gap between the auxiliary roller 21 and the cutting blade 22. The cylindrical sponge cut by the cutting blade 22 will generate waste debris, which flows into the waste receiving chamber 203 through the waste outlet and is collected by the waste collection drawer 26 for subsequent processing.

[0034] Reference Figure 4 and Figure 5 The feeding assembly 3 includes a first support platform 31, a second support platform 32, a fixing member 33, and a sponge mounting rod 34. The sponge mounting rod 34 is detachably mounted on the first support platform 31 and the second support platform 32. A first drive motor is fixedly connected inside the first support platform 31. A first gear is coaxially fixedly mounted on the output shaft of the first drive motor. A second gear is fixedly mounted on one end of the sponge mounting rod 34 with a copper hook. When the sponge mounting rod 34 is mounted on the first support platform 31, the first gear and the second gear mesh, and the sponge mounting rod 34 can rotate around its own central axis through the first drive motor.

[0035] Specifically, there are two fasteners 33, which are respectively located on the first support platform 31 and the second support platform 32. Both the first support platform 31 and the second support platform 32 are provided with mounting rod placement slots 301. The cross-section of the mounting rod placement slots 301 is fan-shaped to match the sponge mounting rod 34, so that both ends of the sponge mounting rod 34 can be stably placed in the two mounting rod placement slots 301 respectively.

[0036] Both the first support platform 31 and the second support platform 32 are fixedly connected to a fixed slide rail 302, and the fixing member 33 slides vertically and is engaged with the fixed slide rail 302. One end of the fixing member 33 is threaded with a tightening bolt 35, and the tightening bolt 35 is correspondingly threaded with the first support platform 31 or the second support platform 32, so that the two fixing members 33 can be lifted upward from the first support platform 31 and the second support platform 32 respectively by loosening their respective tightening bolts 35, thereby facilitating the lifting of the sponge mounting rod 34 out of the mounting rod placement groove 301.

[0037] Reference Figure 4 and Figure 5 A receiving rod 36 is rotatably mounted on the top of the support base 1. The receiving rod 36 is equipped with a second drive motor, which causes the receiving rod 36 to rotate around its own axis. After the cylindrical sponge is cut by the cutting blade 22, the sponge flows out through the gap between the auxiliary roller 21 and the cutting blade 22. The worker then attaches the cut cylindrical sponge to the receiving rod 36 and starts the second drive motor, causing the receiving rod 36 to rotate around its own axis. As the receiving rod 36 rotates, it automatically collects the cut cylindrical sponge, thereby improving work efficiency.

[0038] Reference Figure 5 Two support columns 4 are provided, each containing a trapezoidal lead screw 41. A first support platform 31 and a second support platform 32 are threadedly connected to the trapezoidal lead screw 41 within the two support columns 4. The two support columns 4 slide along the length of the trapezoidal lead screw 41, respectively, with the first support platform 31 and the second support platform 32 connected to the first support platform 31. A third drive motor is located at the top of each support column 4. The output end of the third drive motor is connected to the trapezoidal lead screw 41. As the drive motor drives, the trapezoidal lead screw 41 rotates around its output axis. This rotation affects the first support platform 31 and the second support platform 32, causing them to slide along the length of the trapezoidal lead screw 41, thus adjusting their height for easier installation of the sponge mounting rod 34. Furthermore, the trapezoidal lead screw 41 has a self-locking function, providing a fixed support when replacing the cylindrical sponge on the sponge mounting rod 34, making the installation of the cylindrical sponge easier.

[0039] The implementation principle of the automatic sponge cutting and winding device in this application embodiment is as follows: When a cylindrical sponge needs to be installed, the first step is to start the third drive motor to raise the sponge mounting rod 34 to a suitable position; the second step is to loosen the tightening bolts 35 of the first support platform 31 and the second support platform 32 so that the fixing component 33 no longer fixes the sponge mounting rod 34; the third step is to remove the sponge mounting rod 34 and replace it with a cylindrical sponge; the fourth step is to place the sponge mounting rod 34 with the replaced cylindrical sponge in the mounting rod placement slot 301 of the first support platform 31 and the second support platform 32; the fifth step... Step 1: Engage the second gear of the sponge mounting rod 34 with the first gear of the first drive motor and tighten the bolt 35 to fix the sponge mounting rod 34. Step 2: Use the third drive motor to lower the cylindrical sponge to the position between the auxiliary roller 21 and the cutting blade 22, so that the cylindrical sponge is tightly fitted against the auxiliary roller 21 and the cutting blade 22. Step 3: Start the first drive motor to cut the cylindrical sponge. Step 4: Attach the cut cylindrical sponge to the receiving rod 36 and start the second drive motor to automatically collect the cut cylindrical sponge.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
