Description

Technical Field

[0001] This utility model relates to the field of slicing machine technology, specifically to a slicing machine. Background Technology

[0002] In the traditional Chinese medicine and food processing fields, reciprocating herb slicers are commonly used equipment. Existing herb slicers use independent motors to control feeding and cutting separately. This not only increases the complexity and cost of the equipment, but also makes synchronous control between the two motors difficult, prone to timing errors, resulting in material continuing to move during cutting, causing uneven slice thickness, rough cuts, and even damage to the blades. Furthermore, some simpler machines using a single motor drive have a continuous feeding mechanism, where material is still being pushed forward during the downward cutting process, causing the material to be squeezed and torn by the blades. This not only results in low yield and high losses, but also easily leads to material clogging the blade opening, affecting the continuity of production. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a slicing machine that solves the problem of current slicing machines using separate motors to control feeding and cutting. This not only increases the complexity and cost of the equipment, but also makes synchronous control between the two motors difficult, prone to timing errors, resulting in material still moving during cutting, causing uneven slice thickness, uneven cuts, and even damage to the cutting tools. Furthermore, some simple devices using a single motor drive have a continuous feeding mechanism, where material is still being pushed forward during the downward cutting process, causing the material to be squeezed and torn by the cutting tools. This not only results in low yield and high loss, but also easily leads to material clogging of the cutting gate, affecting the continuity of production.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a slicer, comprising a frame, a small flywheel of a main motor mounted on one side of the frame, a large flywheel and a crankshaft connected to the small flywheel of the main motor via a belt, a connecting rod mounted on the crankshaft, a blade holder fixedly connected to the connecting rod, a blade fixedly connected to one side of the blade holder, an eccentric wheel fixedly connected to the outer wall of the output end of the main motor, a swing arm fixedly connected to the outer wall of the eccentric wheel, and a stepping feeding assembly mounted on the swing arm.

[0005] As a preferred technical solution of this utility model, the stepping feeding assembly includes a friction wheel assembly, which is installed on one side of the outer wall of the frame. The friction wheel assembly meshes with a swing arm, and a gear and sprocket set meshes on the friction wheel assembly. The friction wheel assembly is connected to an eccentric wheel.

[0006] As a preferred embodiment of this utility model, a conveyor chain is installed on the gear and sprocket assembly, and an eccentric shaft is installed on the eccentric wheel.

[0007] As a preferred embodiment of this utility model, a rear support roller is installed on the rear side of the lower surface of the frame, and a sprocket shaft is installed on the front side of the lower surface of the frame. A chain is engaged with the outer wall of the sprocket shaft, and the inner side of the chain is engaged with the outer wall of the rear support roller.

[0008] Compared with the prior art, the present invention provides a slicer with the following advantages: This type of slicer, driven by a main motor, can move a large flywheel and an eccentric wheel, achieving perfect synchronization between cutting and feeding. With the assistance of a stepping feed assembly, it ensures that the material is absolutely stationary with each cut, fundamentally solving problems such as uneven slice thickness, inconsistent cross-sections, and material tearing caused by material movement. This results in high-quality finished products with minimal waste. Because feeding completely stops during cutting, it avoids the squeezing and blockage caused by forcibly pushing material against the blade, greatly improving the smoothness and stability of the equipment's operation.

[0011] 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.

[0012] Example 1 Please see Figure 1-5In this embodiment: a slicer includes a frame 1, a main motor flywheel 2 is mounted on one side of the frame 1, the main motor flywheel 2 is connected to a large flywheel 3 and a crankshaft 4 via a belt, a connecting rod 5 is mounted on the crankshaft 4, a blade holder 6 is fixedly connected to the connecting rod 5, a blade 7 is fixedly connected to one side of the blade holder 6, an eccentric wheel 8 is fixedly connected to the outer wall of the output end of the main motor 2, a swing arm 9 is fixedly connected to the outer wall of the eccentric wheel 8, and a stepping feeding assembly is mounted on the swing arm 9; In this embodiment, the main motor's small flywheel 2 is activated, which drives the pulley to drive a large flywheel 3 and a crankshaft 4. The crankshaft 4 is connected to the tool holder 6 via a connecting rod 5, forming a crank-connecting rod 5 mechanism. When the main motor rotates, the tool holder 6 makes a stable and continuous up-and-down reciprocating linear motion within the guide rail of the frame 1. An eccentric wheel 8 is also connected to the transmission shaft of the main motor. The eccentric pin of the eccentric wheel 8 is hinged to one end of the swing arm 9, and the other end of the swing arm 9 is engaged with the stepper feeding assembly. When the main motor rotates, the eccentric wheel 8 drives the swing arm 9 to swing back and forth around its fulcrum. When the swing arm 9 swings in one direction, the friction block on it drives the stepper feeding assembly to rotate through a certain angle. When the swing arm 9 swings in the opposite direction, the friction block disengages from or slips from the stepper feeding assembly, and no power is transmitted. In this way, the stepper feeding assembly achieves intermittent unidirectional rotation.

[0013] Furthermore, the stepping feeding assembly includes a friction wheel assembly 10, which is mounted on one side of the outer wall of the frame 1. The friction wheel assembly 10 meshes with the swing arm 9, and a gear and sprocket set 11 meshes on the friction wheel assembly 10. The friction wheel assembly 10 is connected to the eccentric wheel 8. A conveyor chain 12 is mounted on the gear and sprocket set 11, and an eccentric shaft 12 is mounted on the eccentric wheel 8. When the main motor rotates, the eccentric wheel 8 drives the rocker arm 9 to reciprocate around its fulcrum. When the rocker arm 9 swings in one direction, the friction block on it engages with the friction wheel assembly 10, driving it to rotate through a certain angle. When the rocker arm 9 swings in the opposite direction, the friction block disengages from or slips from the friction wheel assembly 10, and no power is transmitted. In this way, the friction wheel assembly 10 achieves intermittent unidirectional rotation. The power of the friction wheel assembly 10 is then transmitted to the drive shaft of the conveyor chain 12 through the gear and sprocket set 11, driving the conveyor chain 12 to move forward in a stepping manner. When the crankshaft 4 drives the tool holder 6 to move upward from the lowest point, the eccentric wheel 8 just drives the rocker arm 9 to be in the driving position. During the working stroke of the dynamic friction wheel assembly 10, the conveyor chain 12 carries the material forward a set distance. When the cutter 6 passes the highest point and begins to descend for cutting, the eccentric wheel 8 drives the swing arm 9 to return to the non-working stroke. At this time, the conveyor chain 12 remains stationary, waiting for the blade 7 to complete the cutting. This cycle repeats, achieving perfect coordination between cutting and feeding. The slice thickness is adjusted by adjusting the eccentric shaft 13 on the eccentric wheel 8. By rotating the adjustment handwheel, the eccentric distance of the eccentric shaft 13 relative to the main shaft can be changed. This distance directly determines the swing amplitude of the swing arm 9, and thus determines the step distance of each feeding, i.e., the slice thickness.

[0014] Preferably, a rear support roller 101 is installed on the rear side of the lower surface of the frame 1, and a sprocket shaft 102 is installed on the front side of the lower surface of the frame 1. A chain 103 is engaged with the outer wall of the sprocket shaft 102, and the inner side of the chain 103 is engaged with the outer wall of the rear support roller 101.

[0015] The working principle and usage of this utility model are as follows: Starting the main motor causes the small flywheel 2 to drive the pulley, which in turn drives the large flywheel 3 and crankshaft 4. The crankshaft 4 is connected to the tool holder 6 via a connecting rod 5, forming a crank-connecting rod mechanism. When the main motor rotates, the tool holder 6 makes a stable and continuous reciprocating linear motion within the guide rail of the frame 1. An eccentric wheel 8 is also connected to the transmission shaft of the main motor. The eccentric pin of the eccentric wheel 8 is hinged to one end of the swing arm 9, and the other end of the swing arm 9 engages with the friction wheel assembly 10. When the main motor rotates, the eccentric wheel 8 drives the swing arm 9 to reciprocate around its fulcrum. When the swing arm 9 swings in one direction, the friction block on it engages with the friction wheel assembly 10, driving it to rotate through a certain angle. When the swing arm 9 swings in the opposite direction, the friction block disengages from or slips from the friction wheel assembly 10, and no power is transmitted. In this way, the friction wheel assembly 10 achieves intermittent unidirectional rotation. The power of the friction wheel assembly 10 is then transmitted to the drive shaft of the conveyor chain 12 through the gear and sprocket set 11, driving the conveyor chain 12 to move forward in a stepping manner. When the crankshaft 4 drives the tool holder 6 to move upward from the lowest point, the eccentric wheel 8 drives the swing arm 9 to be in the working stroke of driving the friction wheel assembly 10. At this time, the conveyor chain 12 carries the material forward a set distance. When the tool holder 6 passes the highest point and begins to descend for cutting, the eccentric wheel 8 drives the swing arm 9 to be in the non-working stroke of returning. At this time, the conveyor chain 12 is stationary, waiting for the blade 7 to complete the cutting. This cycle repeats, achieving perfect coordination between cutting and feeding. The slice thickness is adjusted by adjusting the eccentric shaft 13 on the eccentric wheel 8. By rotating the adjustment handwheel, the eccentric distance of the eccentric shaft 13 relative to the main shaft can be changed. This distance directly determines the swing amplitude of the swing arm 9, and thus determines the stepping distance of each feeding, i.e., the slice thickness.
