Description

Technical Field

[0001] This utility model relates to the field of slitting machine equipment, specifically a blade holder for a metal sheet and strip slitting machine. Background Technology

[0002] Metal sheets and strips are flat metal materials produced through processes such as rolling and stretching. They are characterized by uniform thickness and large width, and are widely used in industries such as construction, automobiles, and electronics, providing functions such as structural support, decoration, and conductivity. Common materials include steel, aluminum, and copper, and surface treatments such as plating and coating can be applied to enhance performance as needed.

[0003] In the production of sheet and strip metal, slitting machines are used to cut wide coils into narrow coils of different widths as required to meet downstream processing requirements; the blade holder on the sheet and strip metal slitting machine is the core cutting component, used to fix and adjust the disc blades to achieve slitting.

[0004] The existing blade holder is installed on the slitting machine by inserting both ends into the mounting plate and then fixing them with bolts. However, during use and observation, it was found that the bolts at both ends need to be operated every time the blade holder is installed or disassembled, which affects the operating speed of the blade holder.

[0005] Therefore, a blade holder for a metal sheet and strip slitting machine is proposed to address the above problems. Utility Model Content

[0008] Preferably, a disc is threadedly connected to the end of the tool holder body; a connecting rod is fixedly connected to the side wall of the disc; a sleeve is rotatably connected to the end of the connecting rod; the disc is located opposite the baffle; by adding the disc, it can be fixed at both ends with the baffle, thereby increasing the stability of the tool holder body after placement, and at the same time, the sleeve can be used to rotate without having to release and re-grip, thus increasing convenience during continuous rotation.

[0009] Preferably, a guide block is fixed to the end of the tool holder body; the end of the guide block is set with an inclined surface; by adding a guide block, the speed at which the tool holder body is inserted into the mounting plate can be accelerated by the narrowing end of the guide block when the tool holder body is inserted.

[0010] Preferably, the tool holder body has marking lines on its surface; multiple marking lines are provided on the tool holder body; by adding marking lines, a more intuitive judgment standard can be added when adjusting the blade assembly, thereby making the adjustment of the blade assembly more convenient.

[0011] Preferably, a protective sleeve is slidably fitted onto the surface of the guide block; the protective sleeve and the guide block are interference fit; by adding the protective sleeve, the sharpness of the end of the guide block can be reduced during operation to minimize discomfort during contact, thereby increasing control over the guide block during operation.

[0023] 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 scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a metal sheet and strip slitting machine blade holder includes a slitting machine body 1. A pair of upright plates 11 are fixedly connected to the top of the slitting machine body 1. A guide roller 12 is rotatably connected to the middle of the upright plates 11. A pair of support plates 13 are fixedly connected to the end of the slitting machine body 1. A motor 14 is fixedly connected to the side wall of the support plate 13. An active roller 15 is fixedly connected to the output end of the motor 14. The active roller 15 is rotatably connected to the support plate 13. A passive roller 16 is rotatably connected to the middle of the support plate 13. The passive roller 16 is located below the active roller 15. A pair of electric push rods 103 are fixedly connected to the middle of the slitting machine body 1. A mounting plate 17 is fixedly connected to the top of the electric push rods 103. A blade holder body 18 is threadedly connected to the middle of the mounting plate 17. The tool holder body 18 has threads of different lengths on both ends; a pair of blade assemblies 19 are slidably connected to the middle of the tool holder body 18; a pair of bolts 101 are threadedly connected to the surface of the blade assembly 19; a baffle 102 is fixedly connected to the end of the tool holder body 18; during operation, when installing the tool holder body 18, first insert one end of the long thread into the mounting plate 17 on one side, then rotate it to gradually pass through the first mounting plate 17, then continue to push it closer to the second mounting plate 17 and finally insert it into the mounting plate 17. At the same time, the subsequent threads will also enter the first mounting plate 17. At this time, rotating the threads on both sides of the tool holder body 18 will simultaneously engage with the mounting plates 17. Then, when the baffle 102 and the first mounting plate 17 are connected... The rotation stops upon contact, indicating that the blade holder body 18 is now installed. When slitting the metal strip, the strip is first pulled across the surface of the guide roller 12, then passes under the blade assembly 19, and finally enters the space between the drive roller 15 and the driven roller 16 where it is clamped. After clamping, the motor 14 is started, driving the drive roller 15 to rotate. During rotation, the drive roller 15 and driven roller 16 compress the metal strip, causing it to move forward. During this movement, the blade assembly 19 is unlocked by rotating the bolt 101 on it. The blade assembly 19 can then slide along the surface of the blade holder body 18, adjusting the spacing between the pair of blade assemblies 19 to adjust the slitting size of the metal strip. After adjustment, a pair of bolts 101 are rotated in sequence to contact the tool holder body 18. Upon contact, the two sides of the blade assembly 19 are fixed, thereby positioning the blade assembly 19. At this time, the electric actuator 103 is activated to drive the blade assembly 19 to move down and contact the metal strip for slitting. By providing threads at both ends of the tool holder body 18, the tool holder body 18 can be directly fixed by inserting and engaging the threads during installation. This ensures that the tool holder body 18 is fixed when it is moved to the designated position, thus speeding up the installation and fixing of the tool holder body 18 and reducing the need for adjustment during installation. At the same time, the baffle 102 can restrict the position of the tool holder body 18 during installation, allowing it to stop when the baffle 102 contacts the mounting plate 17, thereby quickly positioning the tool holder body.

[0026] like Figures 1 to 5 As shown, a disc 2 is threadedly connected to the end of the tool holder body 18; a connecting rod 21 is fixedly connected to the side wall of the disc 2; a sleeve 22 is rotatably connected to the end of the connecting rod 21; the disc 2 is located opposite the baffle 102; during operation, after the tool holder body 18 is installed, the disc 2 is sleeved on the end of the tool holder body 18, so that it moves and makes threaded contact with the surface of the tool holder body 18, and then contacts the sleeve 22, so that the disc 2 is driven to rotate through the sleeve 22. When the disc 2 rotates, the sleeve 22 will rotate on the connecting rod 21, thereby rapidly rotating the disc 2 and threadedly engaging it with the tool holder body 18. When the disc 2 contacts the second mounting plate 17, it stops rotating, thereby limiting the other end of the tool holder body 18; by adding the disc 2, it can form a fixed end with the baffle 102, thereby increasing the stability of the tool holder body 18 after placement. At the same time, the sleeve 22 can be held without having to be released and held again during rotation, thereby increasing convenience during continuous rotation.

[0027] like Figures 3 to 4 As shown, a guide block 3 is fixedly connected to the end of the tool holder body 18; the end of the guide block 3 is set with an inclined surface; during operation, when the tool holder body 18 is inserted, the guide block 3 will increase the guidance when it contacts the mounting plate 17, so that the end of the tool holder body 18 is reduced, thereby making it faster when inserted into the mounting plate 17; by adding the guide block 3, the speed at which the tool holder body 18 is inserted into the mounting plate 17 can be accelerated by the reduced end of the guide block 3.

[0028] like Figures 3 to 4 As shown, the tool holder body 18 has marking lines 4 on its surface; multiple marking lines 4 are set on the tool holder body 18; during operation, when adjusting the blade assembly 19, the blade assembly 19 can be quickly adjusted according to the position of the marking lines 4, thereby speeding up the adjustment of the blade assembly 19; by adding marking lines 4, a more intuitive judgment standard can be added when adjusting the blade assembly 19, thus making the adjustment of the blade assembly 19 more convenient.

[0029] like Figures 2 to 3 As shown, a protective sleeve 5 is slidably fitted on the surface of the guide block 3; the protective sleeve 5 and the guide block 3 are interference fit; during operation, after the tool holder body 18 is installed, the protective sleeve 5 is fitted onto the surface of the guide block 3 to close the sharp part at the end of the guide block 3, thereby increasing protection during operation; by adding the protective sleeve 5, the sharp part at the end of the guide block 3 can be reduced during operation to reduce discomfort when in contact, thereby increasing control over the guide block 3 during operation.

[0030] like Figures 2 to 5As shown, an anti-slip cloth 6 is fixedly attached to the surface of the sleeve 22; the anti-slip cloth 6 and the sleeve 22 are correspondingly arranged; during operation, when the sleeve 22 is held, the anti-slip cloth 6 will be located between the skin holding the sleeve and the sleeve 22. At this time, the sleeve 22 will increase the friction between the skin and the sleeve 22 in contact, thus increasing the frictional resistance; by adding the anti-slip cloth 6, the sleeve 22 can be made more responsive to the hand during continuous rotation after being held, thus increasing the stability after holding it.

[0031] Working principle: When installing the tool holder body 18, first insert one end of the long thread into the mounting plate 17 on one side, and then rotate it to gradually pass through the first mounting plate 17. Then continue to push it closer to the second mounting plate 17 and finally insert it into the mounting plate 17. At the same time, the subsequent threads will also enter the first mounting plate 17. At this time, rotating the threads on both sides of the tool holder body 18 will simultaneously engage with the mounting plates 17. Then, when the baffle 102 contacts the first mounting plate 17, the rotation can be stopped. At this time, the installation of the tool holder body 18 is completed. When slitting the metal strip, first pull the metal strip through the surface of the guide roller 12 and then through the area below the blade assembly 19. After passing through, the strip is finally clamped between the drive roller 15 and the driven roller 16. When the motor 14 is started, it drives the drive roller 15 to rotate. During rotation, the drive roller 15 and the driven roller 16 compress the metal strip, causing it to move forward. During this movement, the bolts 101 on the blade assembly 19 are rotated to unlock it. The blade assembly 19 can then slide along the surface of the blade holder body 18, adjusting the spacing between the pair of blade assemblies to adjust the slitting size of the metal strip. After adjustment, the pair of bolts 101 are rotated sequentially to contact the blade holder body 18. Upon contact, the blade assembly 19 will be pressed against both sides. The blade assembly 19 is positioned by fixing it in place. Then, the electric actuator 103 is activated, causing the blade assembly 19 to move downwards and contact the metal strip for slitting. After the tool holder body 18 is installed, the disc 2 is fitted onto the end of the tool holder body 18, allowing it to move and make threaded contact with the surface of the tool holder body 18, and then contact the sleeve 22. The sleeve 22 drives the disc 2 to rotate, and as the disc 2 rotates, the sleeve 22 rotates on the connecting rod 21, causing the disc 2 to rotate rapidly and engage with the tool holder body 18 through a thread. The disc 2 stops rotating when it contacts the second mounting plate 17, thus limiting the other end of the tool holder body 18. The tool holder body 18 is then inserted... When the guide block 3 contacts the mounting plate 17, it increases guidance, causing the end of the tool holder body 18 to narrow, thus allowing for faster insertion into the mounting plate 17. When adjusting the blade assembly 19, it can be quickly adjusted according to the position of the marking line 4, thus accelerating the adjustment speed. After the tool holder body 18 is installed, the protective sleeve 5 is placed on the surface of the guide block 3, closing the sharp part at the end of the guide block 3, thereby increasing protection during operation. When the sleeve 22 is held, the anti-slip cloth 6 is located between the skin and the sleeve 22, which increases the friction between the skin and the sleeve 22, thus increasing the frictional resistance.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
