Description

Technical Field

[0001] This utility model relates to the field of roll material processing technology, and in particular to a double roll even-cutting mechanism. Background Technology

[0002] In the FPC industry, joining two rolls of material requires overlapping the ends of the rolls, cutting the overlapping ends evenly with a cutter, and then bonding the two ends together with an adhesive. Currently, this is mostly done manually, overlapping the two rolls, pressing them together with auxiliary tools, and then cutting them with a hand-held cutter. However, because it's all done manually with auxiliary tools and manual cutting, uneven force is often applied during both the pressing and cutting processes. This can lead to loosening and shifting during pressing and cutting, resulting in uneven cuts of the material ends, which directly affects the subsequent bonding process.

[0003] The technical problem to be solved by this application is: to design a double-roll straight-cutting mechanism that can achieve stable clamping and stable cutting. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a double-rolled, even-cutting blade mechanism that can achieve stable clamping and stable cutting.

[0008] In some embodiments, there are two guide seats and two guide rods, and the drive devices on the left and right fixed plates have the same structure.

[0009] In some implementations, the mounting motherboard has a through slot, and the pressure plate has two plates located on either side of the through slot.

[0010] In some implementations, the mounting motherboard is provided with a guide rail that is fixedly connected thereto, and the cutting mechanism slides with the guide rail.

[0011] In some embodiments, the cutting mechanism includes a sliding seat that slides with the guide rail, the sliding seat having a main pressing block connected thereto, the main pressing block having a cutter connected thereto, and the main pressing block also having a secondary pressing block connected thereto for pressing the cutter.

[0012] In some embodiments, the slide seat is also provided with a handle connected thereto for pushing the slide seat to slide on the guide rail.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a double-rolled, even-cutting blade mechanism, including a left fixed plate 1 and a right fixed plate 2. A vertically movable mounting plate 3 is provided between the left and right fixed plates 1 and 2. The bottom of the mounting plate 3 has a lower pressure plate 4 for pressing the material head. When the mounting plate 3 descends, it drives the lower pressure plate 4 to descend simultaneously, thus pressing the material head for cutting. The mounting plate 3 also has a through groove 30, with two lower pressure plates 4 located on either side of the through groove 30, allowing for pressing of both material heads. The left and right fixed plates 1 and 2 are respectively provided with driving devices 5 for driving the mounting plate 3 to rise and fall. The driving device 5 includes a driving cylinder 50 connected to the left fixed plate 1, with the driving end of the driving cylinder 50 fixedly connected to one end of the mounting plate 3. The driving device 5 also includes a guide rod 51 connected to one end of the mounting plate 3 and a guide seat 52 connected to the left fixed plate 1. To ensure the stability of the lifting and lowering of the mounting plate 3, two guide seats 52 and guide rods 51 are provided between the two plates. The drive devices 5 on the left fixed plate 1 and the right fixed plate 2 have the same structure. Therefore, when it is necessary to press the material head, the two material heads are first placed overlappingly under the mounting plate 3. Then, the mounting plate 3 is driven to descend by the drive cylinder 50, which drives the lower pressure plate 4 at the bottom of the mounting plate 3 to descend simultaneously, thereby pressing the overlapping material heads. In order to ensure the stability of the mounting plate 3 when the drive cylinder 50 drives it to descend, a guide rod 51 is also provided on the mounting plate 3. The guide rod 51 is also limited and slidably engaged with the guide seat 52, thereby ensuring that the mounting plate 3 can descend smoothly. By providing two guide seats 52 on the left fixed plate 1 and the right fixed plate 2 respectively, a four-point matrix guide is achieved for the mounting plate 3, thereby further ensuring that the mounting plate 3 is evenly stressed when descending, so as to achieve stable pressing of the material head.

[0022] A cutting mechanism 6 for cutting material heads is provided on the mounting motherboard 3 and is slidably engaged with it. A guide rail 31 is fixedly connected to the mounting motherboard 3. The cutting mechanism 6 and the guide rail 31 are slidably engaged. The cutting mechanism 6 includes a sliding seat 60 that is slidably engaged with the guide rail 31. A main pressure block 61 is provided on the sliding seat 60 and connected thereto. A cutting blade 62 is provided on the main pressure block 61 and connected thereto. A secondary pressure block 63 for pressing the cutting blade 62 is also provided on the main pressure block 61. A connecting part 610 is provided at the lower end of the main pressure block 61. The connecting part 610 is mirrored at the lower end of the main pressure block 61, which means that the cutting blade 62 can be installed on both sides of the main pressure block 61. The angles at which the cutting blades 62 are installed on both sides are different, which can effectively adapt to cutting different materials or materials of different thicknesses. The secondary pressure block 63 is installed on the connecting part 610 so as to press the cutting blade 62.

[0023] The sliding seat 60 is also provided with a handle 64 connected thereto for pushing the sliding seat 60 to slide on the guide rail 31. By pushing the handle 64, the cutting mechanism 6 can be driven to slide on the guide rail 31. Because the main pressure block 61 extends to the bottom of the main mounting plate through the through groove 30, the cutting blade 62 can neatly cut the material head when the cutting mechanism 6 is pushed. Limit switches 32 are also provided at both ends of the guide rail 31. When cutting the material head, the cutting blade 62 can only be considered to have cut the material head in place after the cutting mechanism 6 touches the limit switches 32 at both ends. Otherwise, it is considered that the cutting is not completed.

[0024] The working principle of this utility model is as follows: A lower pressure plate 4 is provided at the bottom of the liftable mounting main board 3, and a driving device 5 is provided on the left fixed plate 1 and the right fixed plate 2 respectively. By using the driving device 5 to drive the mounting main board 3 to descend, the lower pressure plate 4 located at the bottom of the mounting main board 3 presses the material head, thereby ensuring that the lower pressure plate 4 applies uniform force when pressing the material head, thus ensuring the pressing stability of the material head. Furthermore, a sliding cutting mechanism 6 is provided on the mounting main board 3. After the material head is stably pressed by the lower pressure plate 4, the cutting mechanism 6 slides on the mounting main board 3 to stably cut the material head. By making the cutting mechanism 6 move linearly along the guide rail 31 to cut, the straightness of the cutting blade 62 during the cutting process can be effectively ensured, thereby achieving a flat cut.
