[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] To address the technical problem of safety hazards during auxiliary feeding and unloading of copper foil strip cutting machines due to the lack of protective facilities at the feeding rollers and cutter 3, this utility model provides a protective device for copper foil strip cutting machines. This device allows for the installation of a second protective plate 5 and a first protective plate 4 on the main body 1, respectively, opposite the feeding rollers 2 and cutter 3. These protect the exposed feeding rollers 2 and cutter 3, preventing potential safety hazards. Simultaneously, the first protective plate 4 is detachably connected to the main body 1 via at least one connector 61, facilitating disassembly and use, maintenance, and repair.

[0032] It should be noted that the protective device for copper foil cutting machines described in this utility model is used in, but not limited to, the field of lithium battery copper foil production technology. For ease of explanation, this utility model only uses the application of the protective device for copper foil cutting machines in the field of lithium battery copper foil production technology as an example for explanation. The principle of the protective device for copper foil cutting machines applied to other types of equipment is essentially the same as the principle applied to the field of lithium battery copper foil production technology, and will not be described in detail here.

[0033] Please see Figures 1 to 5 , Figure 1This is a schematic diagram of the structure of a protective device for a copper foil cutting machine in one embodiment of the present invention. The protective device is connected to the cutting machine, which includes a main body 1, a feeding roller 2, and a cutter 3. The device includes a first protective plate 4, a second protective plate 5, and a connecting assembly 6. The first protective plate 4 covers the cutter 3, and the second protective plate 5 is disposed opposite to the feeding roller 2 and connected to the main body 1. The connecting assembly 6 includes at least one connector 61, which is connected to the main body 1 and detachably connected to the first protective plate 4.

[0034] In this device, the strip cutter includes a main body 1, a feeding roller 2 and a cutter 3. A first protective plate 4 is placed over the cutter 3 and is detachably connected to the main body 1 via at least one connector 61 to protect the cutter 3. A second protective plate 5 is disposed opposite to the feeding roller and connected to the main body 1 to protect the feeding roller 2.

[0035] Compared to existing technologies, a second protective plate 5 and a first protective plate 4 are respectively installed on the main body 1 relative to the feeding roller 2 and the cutter 3 to shield and protect the exposed feeding roller 2 and cutter 3, avoiding potential safety hazards. At the same time, the first protective plate 4 is detachably connected to the main body 1 via at least one connector 61, which facilitates the user to disassemble the first protective plate 4, making it convenient for use, maintenance and repair. This solves the problem in existing technologies where there are no protective facilities at the feeding roller and cutter 3 of the strip cutting machine, resulting in safety hazards for workers when assisting with feeding and unloading.

[0036] Furthermore, the slitting machine in this device is used to produce lithium battery copper foil in strips. The cutter 3 and the feeding roller 2 are spaced apart on the main body 1. The material is fed into the feeding roller 2 and conveyed to the cutter 3 to be cut into strips, and then conveyed to the discharge end. There are no protective devices on the top and sides of the cutter 3 and the feeding roller 2. This can be referred to in the Chinese utility model patent with publication number CN212655246U, entitled "Slitting and Slicing Machine". This is a conventional setting known to those skilled in the art and will not be described in detail here.

[0037] In one embodiment, please refer to Figure 1 , Figure 3 The connecting component 6 has two connectors 61, which are respectively connected to both sides of the cutter 3 and are detachably connected to the first protective plate 4.

[0038] Two connectors 61 are respectively located on both sides of the cutter 3 to improve the stability of the connection between the first protective plate 4 and the main body 1, and to prevent the first protective plate 4 from accidentally falling off after installation and affecting the normal production and stable operation of the device.

[0039] In this embodiment, as Figure 3 , Figure 6 As shown, the connector 61 has a slot in the vertical direction, the first protective plate 4 is L-shaped and has a snap-fit ​​section 41 and an overlap section 42. The two ends of the snap-fit ​​section 41 are slidably inserted into the slot, and the overlap section 42 abuts against both connectors 61.

[0040] By engaging the two ends of the snap-fit ​​segment 41 with the slots of the two connectors 61 respectively, and overlapping the segment 42 above the two connectors 61, the installation of the first protective plate 4 can be achieved.

[0041] Furthermore, the width of the slot is greater than the thickness of the snap-fit ​​segment 41, which facilitates the sliding of the snap-fit ​​segment 41 along the guide of the slot, making it easy for the user to install and remove.

[0042] In one embodiment, the first protective plate 4 is light-transmitting.

[0043] To facilitate users' observation of production progress, the first protective plate 4 is light-transmitting.

[0044] Furthermore, the first protective plate 4 here uses a transparent acrylic sheet that is common and readily available on the market. It not only has light transmission but also a certain degree of protective strength. This is a conventional setting known to those skilled in the art and will not be described in detail here.

[0045] In this embodiment, as Figure 6 , Figure 7 As shown, the strip cutting machine also includes an electrical control component 7, which is connected to the main body 1 and electrically connected to the feeding roller 2 and the cutter 3. It is used to control the feeding roller 2 and the cutter 3. The connecting component 6 also includes a micro switch 62, which is electrically connected to the electrical control component 7 and has a fixed end 621 and a touch end 622. The fixed end 621 of the micro switch 62 is connected to the connector 61, and the touch end 622 is set on the sliding path of the snap-fit ​​segment 41. The snap-fit ​​segment 41 slides along the guide of the snap-fit ​​groove and can abut against the touch end 622 of the micro switch 62, so that the micro switch 62 can feed back an electrical signal to the electrical control component 7.

[0046] By electrically connecting the micro-switch to the electronic control component 7 of the cutter 3 machine, the micro-switch can feed back an electrical signal to the electronic control component 7. When the locking segment 41 slides along the guide of the slot and can abut against the touch end 622 of the micro switch 62, the micro-switch feeds back an electrical signal to the electronic control component 7, and safe production can be carried out here. If the locking segment 41 slides along the guide of the slot and does not abut against the touch end 622 of the micro switch 62, no electrical signal is fed back to the electronic control component 7, and safe production cannot be carried out.

[0047] Furthermore, the electronic control component 7 here can realize intelligent control of the slicing machine. You can refer to the Chinese utility model patent with publication number CN212655246U, entitled "Slicing Machine". This is a conventional setting known to those skilled in the art. The micro-control switch is a common and readily available device on the market, which is a conventional setting known to those skilled in the art, and will not be described in detail here.

[0048] In one embodiment, please refer to Figure 6 The outer wall of the connector 61 is also provided with a connecting groove, which is connected to the card slot. The touch end 622 of the micro switch 62 passes through the connecting groove and is built into the card slot.

[0049] The micro switch 62 is disposed on the outer wall of the connector 61, and the touch end 622 of the micro switch 62 is embedded in the card slot through the connecting groove.

[0050] In one embodiment, please refer to Figure 6 The connecting component 6 also includes a rotating shaft 63 and a lever 64. The two ends of the rotating shaft 63 are fixedly connected to the inner walls of opposite sides of the connecting groove, and the middle part of the lever 64 is rotatably connected to the rotating shaft 63. One end of the lever 64 is built into the sliding path of the snap-fit ​​segment 41, and the other end is set relative to the touch end 622 of the micro switch 62, and can be rotated to abut against the touch end 622 of the micro switch 62.

[0051] To ensure that the micro switch 62 can be smoothly triggered after the snap-fit ​​segment 41 slides along the slot, a lever 64 that can rotate relative to it is also provided in the connecting slot. The micro switch is triggered by pushing the lever 64 to rotate through the snap-fit ​​segment 41, which can improve the stability of the device operation and improve the safety of production.

[0052] In one embodiment, please refer to Figures 2 to 4 The inner side wall of the card slot also has two locking holes. The two locking holes are spaced apart along the length of the card slot. The locking holes are connected to the card slot and extend to the outer wall of the through connector 61. The snap-fit ​​segment 41 has a connecting hole relative to the locking hole. The connecting component 6 also includes four locking pins 65. The locking pins 65 are set one-to-one with the locking holes. The locking pins 65 pass through the connecting holes and are inserted into the locking holes.

[0053] By setting a locking pin 65 on one side of the connector 61, the stability of the first protective plate 4 connected to the two connectors 61 is increased, and the accidental detachment of the first protective plate 4 during the production process is prevented.

[0054] Furthermore, the locking pin 65 here is a bolt or pin that is common and readily available in the market. This is a conventional setting known to those skilled in the art, and will not be described in detail here.

[0055] In this embodiment, as Figure 3 As shown, the strip cutting machine also includes two feeding shaft pressure adjustment knobs 8. The two feeding shaft pressure adjustment knobs 8 are respectively set on both sides of the feeding rubber roller 2 and are both connected to the top of the main body 1. The two ends of the second protective plate 5 are respectively provided with grooves opposite to the two feeding shaft pressure adjustment knobs 8. The second protective plate 5 overlaps the top of the main body 1, and the grooves cooperate and engage with the feeding shaft pressure adjustment knobs 8.

[0056] The second protective plate 5 achieves a detachable connection with the main body 1 by engaging with the two feeding shaft pressure adjustment knobs 8 through the grooves at both ends of its plate.

[0057] Furthermore, the feeding shaft pressure adjustment knob 8 here is a device used on the slicing machine to adjust the feeding shaft pressure. You can refer to the Chinese utility model patent with publication number CN212655246U, entitled "Slicing and Slicing Machine". This is a conventional setting known to those skilled in the art, and will not be described in detail here.

[0058] In one embodiment, please refer to Figure 5 The second protective plate 5 is L-shaped and has light transmission. The second protective plate 5 has a first segment 51 and a second segment 52. The first segment 51 is set perpendicular to the second segment 52. Two grooves are opened at both ends of the first segment 51. The second segment 52 is connected to the first segment 51 and covers one side of the feed roller.

[0059] The L-shaped second protective plate 5 can protect the top and sides of the feed roller, improving production safety.

[0060] Furthermore, the second protective plate 5 here uses a transparent acrylic sheet that is common and readily available on the market. It not only has light transmission but also a certain degree of protective strength. This is a conventional setting known to those skilled in the art and will not be described in detail here.

[0061] To better understand this utility model, the following is combined with... Figures 1 to 7 The technical solution of this utility model is described in detail below:

[0062] The strip cutting machine includes a main body 1, a feeding roller 2, and a cutter 3. A first protective plate 4 covers the cutter 3 and is detachably connected to the main body 1 via at least one connector 61, providing protection for the cutter 3. A second protective plate 5 is positioned opposite the feeding roller and connected to the main body 1, providing protection for the feeding roller 2. Compared to the prior art, the second protective plate 5 and the first protective plate 4 are respectively positioned on the main body 1 opposite the feeding roller 2 and the cutter 3, shielding and protecting the exposed feeding roller 2 and the cutter 3 to avoid safety hazards. At the same time, the first protective plate 4 is detachably connected to the main body 1 via at least one connector 61, making it convenient for users to disassemble the first protective plate 4 for use, maintenance, and repair.

[0063] In the specific working process of this utility model, the user first aligns the two grooves of the second protective plate 5 with the two feeding shaft pressure adjustment knobs 8, and then covers the feeding roller 2 with the second protective plate 5. Next, the snap-fit ​​segment 41 is inserted into the slot along the guide of the slot. Then, the snap-fit ​​segment 41 abuts against the lever 64 and pushes the lever 64 to rotate relative to the slot. After rotation, the lever 64 abuts the touch end 622 of the micro switch 62, and the micro switch 62 sends an electrical signal to the electronic control component 7. Finally, the snap-fit ​​segment 42 abuts against the two connecting parts 61, where the connecting hole and the locking hole are aligned. Then, the locking pin 65 is inserted into the connecting hole and the locking hole in sequence. At this point, the first protective plate 4 and the second protective plate 5 are installed, and the strip cutting machine can operate safely.

[0064] This device, through the aforementioned structure, can solve the problem in the prior art where the feeding roller and the cutter of the strip cutting machine lack protective facilities, resulting in safety hazards for workers assisting with feeding and unloading.

[0065] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model.
