Description
Technical Field
[0001] This utility model relates to the field of cigarette equipment technology, and in particular to a slicing machine cutter locking device and a slicing machine. Background Technology
[0002] Tobacco slicing machines are key pieces of equipment in the tobacco industry used to cut materials into shreds or flakes. During operation, the cutting system needs to have rapid and reliable braking capabilities to ensure production safety, guarantee cutting accuracy, and allow for precise stopping of the cutter during maintenance.
[0003] The blade braking system is the core component for achieving this function. Existing slicing machine braking systems mostly employ a simple push-rod structure. When the blade needs to be stopped, the push rods are brought closer together to clamp it, thus stopping the operation. This direct clamping of the blade by existing slicing machine braking systems easily causes wear on the blade surface, reducing its lifespan. Furthermore, the contact surface between the push rods and the blade is prone to wear during long-term operation, reducing the reliability of the push rod clamping. In addition, the blade generates significant impacts during operation, and under frequent braking impact loads, it is prone to loosening and deformation, leading to brake system failure and posing a safety hazard to the slicing machine.
[0004] Therefore, there is an urgent need for a slicing machine blade locking device and a slicing machine to solve the above-mentioned technical problems. Utility Model Content
[0005] The purpose of this utility model is to provide a slicing machine blade locking device and a slicing machine. The slicing machine blade locking device stops the blade by clamping the brake block, avoiding wear on the blade surface. It can also adjust the locking component according to different specifications of brake blocks to improve the reliability of brake block locking.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] On the one hand, a slicing machine blade locking device is provided, comprising:
[0008] frame;
[0009] Brake block, the brake block being used to connect the cutter;
[0010] The locking assembly includes two locking assemblies, which are respectively located on both sides of the brake block along the first direction and are symmetrically arranged about the brake block. Both locking assemblies are connected to the frame.
[0011] A drive assembly is driven to the two locking assemblies, and the drive assembly is capable of driving the two locking assemblies to clamp or release the brake block;
[0012] The device includes two limiting components, both of which are adjustablely connected to the frame. Each limiting component corresponds to a locking component. When the locking component is not clamping the brake block, it abuts against the limiting component. When the locking component clamps the brake block, it disengages from the limiting component.
[0013] In some possible implementations, the locking assembly includes a locking element and a rotating shaft, the rotating shaft being connected to the frame and the locking element being rotatably connected to the rotating shaft.
[0014] In some possible implementations, the locking member has a clamping surface on the side facing the brake block, and the clamping surface is arc-shaped.
[0015] In some possible implementations, the limiting assembly includes a limiting member that is adjustablely connected to the frame along the first direction. The limiting member is located on the side of the locking member facing away from the brake block. When the locking assembly is not clamping the brake block, the locking member abuts against the corresponding limiting member.
[0016] In some possible implementations, the frame is provided with a threaded hole extending along the first direction, the limiting member is provided with an external thread corresponding to the threaded hole, and the limiting member is threadedly connected to the threaded hole.
[0017] In some possible implementations, the limiting component further includes a locking nut that is threadedly connected to the limiting member.
[0018] In some possible implementations, the limiting component further includes an elastic element connected to the side of the limiting component facing the brake block.
[0019] In some possible implementations, the drive assembly includes two cylinders, each corresponding to one of the locking assemblies, and the cylinders are driven to the locking assemblies.
[0020] On the other hand, a slicer is provided, including a cutter and the above-described slicer cutter locking device, wherein the cutter is connected to the brake block.
[0021] In some possible implementations, the slicer further includes a control unit, and the drive assembly is communicatively connected to the control unit.
[0022] The beneficial effects of this utility model are:
[0023] This utility model provides a slicing machine blade locking device and a slicing machine. The slicing machine blade locking device includes a frame, locking components, a drive component, a limiting component, and a brake block. The brake block is used to connect the blade. Two locking components are provided, located on opposite sides of the brake block along a first direction and symmetrically arranged about the brake block. Both locking components are connected to the frame. The drive component is connected to the two locking components and can drive the two locking components to clamp or release the brake block. Two limiting components are provided, both adjustablely connected to the frame. The limiting components correspond one-to-one with the locking components. When the locking component is not clamping the brake block, it abuts against the limiting component. When the locking component clamps the brake block, it disengages from the limiting component. The blade is connected to the brake block. By clamping the brake block, the two locking components stop the brake block, thereby stopping the blade. This avoids direct contact between the locking components and the blade, preventing wear on the blade surface and improving the blade's service life. By incorporating a limiting component, the locking component can be limited when the brake block is released, ensuring a shorter path for the locking component to clamp the brake block and enabling rapid clamping. Furthermore, the position of the limiting component is adjustable, allowing for adjustment of the initial position of the locking component when the brake block is released, adapting it to brake block widths. Simultaneously, as the locking component wears, adjusting the position of the limiting component can also adjust the distance between the locking component and the brake block, maintaining a greater clamping force and improving the reliability of brake block clamping. Additionally, the locking component completely disengages from the limiting component when clamping the brake block, preventing impact from the locking component to the limiting component.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0032] like Figure 1 and Figure 2 As shown, this embodiment provides a slicing machine blade locking device. The slicing machine blade locking device includes a frame 1, a locking assembly 2, a drive assembly 3, a limiting assembly 4, and a brake block 5. The brake block 5 is used to connect the blade. There are two locking assemblies 2, which are respectively located on both sides of the brake block 5 along a first direction and are symmetrically arranged about the brake block 5. Both locking assemblies 2 are connected to the frame 1. The drive assembly 3 is driven and connected to the two locking assemblies 2. The drive assembly 3 can drive the two locking assemblies 2 to clamp or release the brake block 5. There are two limiting assemblies 4, which are both adjustablely connected to the frame 1. The limiting assemblies 4 correspond one-to-one with the locking assemblies 2. When the locking assembly 2 is not clamping the brake block 5, the locking assembly 2 abuts against the limiting assembly 4. When the locking assembly 2 clamps the brake block 5, the locking assembly 2 disengages from the limiting assembly 4.
[0033] In this embodiment, the cutter is connected to the brake block 5. The two locking components 2 clamp the brake block 5, stopping its operation and thus the cutter. This prevents the locking components 2 from directly contacting the cutter, avoiding wear on the cutter surface and extending its service life. By setting the limiting component 4, the locking component 2 can be limited when the brake block 5 is released, ensuring a shorter path for clamping the brake block 5 and enabling rapid clamping. Furthermore, the position of the limiting component 4 is adjustable, allowing the initial position of the locking component 2 in the released state to be adjusted according to different widths of brake blocks 5, making it suitable for brake blocks of varying widths. Simultaneously, when the locking component 2 wears down, adjusting the position of the limiting component 4 can also adjust the distance between the locking component 2 and the brake block 5, maintaining a larger clamping force and improving the reliability of clamping the brake block 5. In addition, the locking component 2 is completely disengaged from the limiting component 4 when clamping the brake block 5, thus preventing the locking component 2 from impacting the limiting component 4.
[0034] Specifically, the first direction is Figure 1 The X-direction is defined as the width direction of the brake block 5. The frame 1 is U-shaped, including a horizontal bar 11 and two vertical bars 12. The horizontal bar 11 extends along the first direction, and the two vertical bars 12 extend vertically and are connected to both ends of the horizontal bar 11. The brake block 5 is elongated and extends vertically, with the two vertical bars 12 symmetrically arranged about the brake block 5. Both locking components 2 are connected to the horizontal bar 11, and the limiting components 4 correspond one-to-one with the vertical bars 12 and are connected to them. The surface roughness of the brake block 5 is greater than that of the cutter surface, which increases the friction between the brake block 5 and the locking components 2, thereby improving the clamping effect of the locking components 2 on the brake block 5.
[0035] Optionally, the locking assembly 2 includes a locking member 21 and a rotating shaft 22. The rotating shaft 22 is connected to the frame 1, and the locking member 21 is rotatably connected to the rotating shaft 22. The drive assembly 3 drives the first ends of the two locking members 21 to rotate in a direction away from each other, and the second ends of the two locking members 21 to rotate in a direction closer to each other, thereby clamping the brake block 5 between the two locking members 21. The structure of the locking member 21 and the rotating shaft 22 improves the locking effect of the locking assembly 2 on the brake block 5.
[0036] Specifically, the locking member 21 is rod-shaped, with a shaft hole in its middle, and a rotating shaft 22 is fixedly connected to the crossbar 11. The rotating shaft 22 is rotatably connected within the shaft hole. The limiting component 4 corresponds to the second end of the locking component 2 and can abut against the second end of the locking component 2. In other embodiments, the two locking members 21 can also be driven by the driving component 3 to move closer to each other along the first direction to clamp the brake block 5.
[0037] Optionally, the locking member 21 has a clamping surface 211 on the side facing the brake block 5, and the clamping surface 211 is arc-shaped. Setting the clamping surface 211 to be arc-shaped can increase the contact area between the locking member 21 and the brake block 5, improve the friction between the locking member 21 and the brake block 5, further improve the clamping effect of the locking member 21 on the brake block 5, and at the same time, avoid stress concentration that could damage the brake block 5.
[0038] Optionally, the limiting assembly 4 includes a limiting member 41, which is adjustablely connected to the frame 1 along a first direction. The limiting member 41 is located on the side of the locking member 21 facing away from the brake block 5. When the locking assembly 2 is not clamping the brake block 5, the locking member 21 abuts against the corresponding limiting member 41. By adjusting the position of the limiting member 41 along the first direction, the distance between the two limiting members 41 can be adjusted, thereby adjusting the angle of the locking member 21 when it is not clamping the brake block 5, and thus adjusting the distance of the second end of the locking assembly 2. Specifically, the limiting member 41 is rod-shaped. The end of the limiting member 41 facing the locking member 21 is flat, and the side wall of the locking member 21 near the second end is provided with an abutment surface. The abutment surface is located on the side facing away from the brake block 5, and the abutment surface is flat, improving the stability when the limiting member 41 abuts against the locking member 21.
[0039] Furthermore, the frame 1 is provided with a threaded hole extending in the first direction, and the limiting member 41 is provided with an external thread corresponding to the threaded hole, and the limiting member 41 is threadedly connected to the threaded hole. By rotating the limiting member 41, the limiting member 41 can move in the first direction, which facilitates the adjustment of the limiting member 41. Specifically, the vertical rod 12 is provided with a threaded hole. In other embodiments, a through hole extending in the first direction can also be provided on the frame 1, and the limiting member 41 passes through the through hole and can move relative to the through hole. The frame 1 is provided with a positioning hole communicating with the through hole, and the positioning hole is provided with an internal thread. A screw is threadedly connected to the positioning hole, and rotating the screw can tighten and fix the limiting member 41.
[0040] Optionally, the limiting component 4 also includes a locking nut 42, which is threadedly connected to the limiting member 41. After the limiting member 41 is adjusted to a suitable position, the locking nut 42 is tightened so that it abuts against the side wall of the vertical rod 12, thereby fixing the limiting member 41 and preventing it from loosening.
[0041] Optionally, the limiting component 4 also includes an elastic element connected to the side of the limiting component 41 facing the brake block 5. By providing the elastic element, the limiting component 41 makes elastic contact with the brake block 5, thereby improving the impact resistance of the limiting component 41. The elastic element can be a spring or a washer made of elastic material.
[0042] Optionally, the drive assembly 3 includes two cylinders 31, each corresponding to a locking assembly 2, and the cylinders 31 are driven and connected to the locking assembly 2. This configuration simplifies the structure and reduces the cost of the drive assembly 3.
[0043] Specifically, the drive assembly 3 also includes two rotating rods, each corresponding to a cylinder 31. The first end of each rotating rod is hinged to the extended end of the cylinder 31, and the second end is hinged to the first end of the locking member 21. By configuring the rotating rods, the linear motion of the cylinder 31 can be converted into the rotational motion of the locking member 21. In another embodiment, a double-acting cylinder can be used to drive the two locking members 21 to rotate in opposite directions. In other implementations, the cylinder 31 can be replaced with a hydraulic cylinder or an electric actuator.
[0044] This embodiment also provides a slicer. The slicer includes a cutter and the aforementioned slicer cutter locking device, with the cutter connected to the brake block 5. In this embodiment, the slicer clamps the brake block 5 using the locking assembly 2, causing the brake block 5 to stop operating, thereby stopping the cutter. This avoids direct contact between the locking assembly 2 and the cutter, preventing wear on the cutter surface and improving the cutter's service life. Furthermore, when the locking assembly 2 wears down, adjusting the position of the limiting assembly 4 allows the locking assembly 2 to maintain a large clamping force, improving the reliability of clamping the brake block 5.
[0045] Furthermore, the slicer also includes a control unit, and the drive assembly 3 is communicatively connected to the control unit. When the slicer malfunctions, it feeds a signal back to the control unit, which then transmits the signal to the drive assembly 3, causing the drive assembly 3 to drive the locking member 21 to clamp the brake block 5, thereby achieving automated control. Specifically, the slicer also includes a detection unit capable of detecting whether the slicer has malfunctioned. The detection unit can be a sensor or a switch, and this embodiment does not limit this.
[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
