Description

Technical Field

[0001] The utility model relates to the technical field of food processing machines, in particular to a conveying mechanism with self-adaptive pressing force. Background Art

[0002] As a medicinal and edible material, Chinese yam is one of the earliest plants used by humans. Chinese yam has the effects of nourishing and strengthening, helping digestion, and stopping diarrhea, and can relieve and treat various diseases. Chinese yam has great development prospects in the food industry and processing industry. The consumption of Chinese yam requires slicing or cutting into sections. Relying solely on manual slicing or cutting is extremely labor-intensive and time-consuming. The structures of the slicing machines on the market are relatively simple and have single functions. However, there are many structural patterns of slicing machines, and most of them are rotary structures. The current slicing machines have low efficiency and are prone to jamming.

[0003] The utility model patent with the authorization announcement number of CN 221160595 U discloses a Chinese yam slicing machine, which includes a working box. One side of the top of the working box is fixedly installed with a second connecting plate, and one side of the second connecting plate is fixedly installed with a first electric push rod, and the output end of the first electric push rod is provided with a connecting frame. After peeling the Chinese yam, it is placed inside the connecting box. By setting the motor to work, the limiting frame moves the Chinese yam into the inside of the chute. By setting the second electric push rod to work, the push plate pushes the Chinese yam to achieve automatic feeding, reducing a large amount of manual operation, thereby reducing the labor of the operators. By setting the first electric push rod to work, the cutting knife slices the Chinese yam inside the cutting groove four times to the left and right respectively. In this way, not only can the Chinese yam be quickly sliced, improving the working efficiency of the slicing of this equipment, but also the situation that the Chinese yam slices stick to one side of the cutting knife can be reduced, thereby ensuring the normal operation of this equipment.

[0004] However, this Chinese yam slicing machine still has the following defects: during the process of slicing Chinese yam, it cannot arrange the Chinese yam regularly, resulting in irregular Chinese yam slices; the Chinese yam is prone to sliding on the conveyor belt; the Chinese yam residues generated on the conveyor belt cannot be cleaned in time, which will affect the performance of the conveying mechanism after a long time. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a conveying mechanism with self-adaptive pressing force, which solves the problems raised in the above background art.

[0006] The technical solution of the utility model is as follows:

[0007] Further, a conveying mechanism with self - adapting pressing force includes a frame. A table is arranged at the left side of the frame in a connected manner. Electric rollers rotatably connected are arranged on the left and right sides at the upper end of the frame. A first conveyor belt for transporting yams is wound between the two electric rollers. Above the first conveyor belt, a yam arranging structure and a conveying structure for stably transporting yams are arranged in sequence from left to right. A brush wheel for brushing off yam residues on the first conveyor belt is arranged at the lower end of the right - hand electric roller.

[0008] Further, the arranging structure includes support seats fixed on both sides at the upper end of the frame, two threaded rods, a number of moving plates and first nuts. The two ends of the threaded rods are fixedly connected to the support seats. The two threaded rods penetrate through the moving plates, and first nuts are arranged on the front and rear sides of the moving plates in a mutually contacting manner.

[0009] Further, the conveying structure includes a second conveyor belt wound between two driven rollers arranged left and right, connecting plates rotatably installed at the ends of the two driven rollers, and a pressing shaft pressing against the upper surface of the second conveyor belt. The transmission shafts fixedly connected to both ends of the left - hand driven roller are rotatably connected to second bearing seats. The connecting shafts extending from both ends of the pressing shaft are rotatably connected to fixed blocks. A strip - shaped rod fixedly connected to the bottom end of the fixed block penetrates through the frame. A stop block is fixedly connected to the bottom end of the strip - shaped rod. A spring sleeved on the strip - shaped rod has one end pressing against the lower side of the frame and the other end pressing against the stop block.

[0010] Further, a first gear is fixedly connected to the end of the transmission shaft extending out of the second bearing seat at one end of the left - hand driven roller. A second gear meshing with the first gear is arranged below the first gear. A first sprocket is fixedly connected to the inner side of the second gear.

Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than 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 efforts shall fall within the protection scope of the present utility model.

[0019] As Figures 1-4 shown, a conveying mechanism with self - adapting pressing force includes a frame 1. A connected tabletop 7 is arranged on the left side of the frame 1. Rotationally connected electric rollers 4 are arranged on the upper left and right sides of the frame 1. A first conveyor belt 5 for transporting yams is wound between the two electric rollers 4. An arrangement structure 8 for arranging yams and a conveying structure 9 for stably transporting yams are sequentially arranged from left to right on the upper end of the first conveyor belt 5. A brush wheel 12 for brushing yam residues on the first conveyor belt 5 is arranged at the lower end of the right - hand electric roller 4.

[0020] Specifically, the frame 1 is composed of several square steels. To reduce the weight of the overall machine, the square steels used are of hollow structure; the frame 1 includes a structure in the shape of a Chinese character "mu" welded by multiple horizontally placed square steels, and vertical square steels are welded at the four corners of the square steels in the shape of a Chinese character "mu". To enhance the stability of the frame 1, horizontal square steels are welded between the two vertical square steels; a fence 6 is provided at the left end of the frame 1, and a tabletop 7 for placing yams is fixedly connected inside the fence 6. The fence 6 and the tabletop 7 are made of stainless steel material; a support plate 2 is fixedly connected to the inner side of the vertical square steel close to the tabletop 7. The support plate 2 is in an L shape, and a bearing is fixedly connected inside the support plate 2. The extension shafts at both ends of the left electric roller 4 are rotatably connected in the bearing, and the outer surface of the right vertical square steel is fixedly connected with a first bearing seat 3. The extension shafts at both ends of the right electric roller 4 are rotatably connected in the first bearing seat 3;

[0021] The first conveyor belt 5 is made of anti-slip rubber material to increase the friction during yam transmission. The width of the first conveyor belt 5 is the same as the distance between the opposite surfaces of the two vertical square steels on the wide side to prevent the slices from falling to the ground. The inclined surface on the tabletop 7 is placed on the upper end of the first conveyor belt 5; a support frame 11 is fixedly connected below the first bearing seat 3. A bearing is provided inside the support frame 11, and the extension shafts at both ends of the brush wheel 12 are inserted into the bearing. By setting the brush wheel 12, the yam residues generated on the first conveyor belt 5 can be cleaned to prevent blockage and improve the performance of the conveying mechanism;

[0022] When slicing is required, place the yam to be sliced on the tabletop 7, start the electric roller 4, start the motor 14, place the yam in the arrangement structure 8. The first conveyor belt 5 rotates, driving the yam to move to the right, facilitating the regular arrangement of the yam during transmission and preventing the yam from shifting, resulting in irregular yam slices; when the yam moves to the lower end of the conveying structure 9, it squeezes the yam to move forward, maintaining the stability of the yam during transmission and preventing slipping.

[0023] As Figure 2 shown, the arrangement structure 8 includes support seats 81 fixed on both sides of the upper end of the frame 1, two threaded rods 82, several moving plates 83 and first nuts 84. The two ends of the threaded rods 82 are fixedly connected to the support seats 81. The two threaded rods 82 are inserted through the moving plates 83, and first nuts 84 that are in contact with each other are arranged on the front and rear sides of the moving plates 83.

[0024] Specifically, the support base 81 is L-shaped, and a bearing is provided on the support base 81. Both ends of the threaded rod 82 are inserted into the bearing. A semi-elliptical connecting block is fixedly connected to the upper end of the moving plate 83 at positions corresponding to the two threaded rods 82. A hole having the same diameter as the threaded rod 82 is formed in the connecting block. A certain distance is left between the bottom end of the moving plate 83 and the first conveyor belt 5 to prevent the moving plate 83 from continuously rubbing against the first conveyor belt 5 and causing damage to the first conveyor belt 5. When moving the moving plate 83, the moving plates 83 at the outermost sides are kept at a certain distance from the edge of the first conveyor belt 5, and the yams are only placed between the two moving plates 83 to ensure smoothness during the transmission process and prevent dislocation. Before the yams are transmitted, the yams are regularly arranged between the two moving plates 83. When placing the yams, avoid over-tightening and stacking to prevent them from not being able to move forward. When moving the moving plate 83, only need to turn the first nuts 84 on both sides, and the process is convenient and easy to operate.

[0025] As Figure 3 shown, the conveying structure 9 includes a second conveyor belt 92 wound between two driven rollers arranged left and right, connecting plates 93 rotatably installed at the ends of the two driven rollers, and a pressing shaft 94 abutting against the upper surface of the second conveyor belt 92. The transmission shafts fixedly connected to both ends of the left driven roller are rotatably connected to the second bearing seats 91. The connecting shafts 95 extending from both ends of the pressing shaft 94 are rotatably connected to the fixing blocks 96. The strip-shaped rod 97 fixedly connected to the bottom end of the fixing block 96 penetrates through the frame 1. A stop block 99 is fixedly connected to the bottom end of the strip-shaped rod 97. One end of the spring 98 sleeved on the strip-shaped rod 97 abuts against the lower side surface of the frame 1, and the other end abuts against the stop block 99.

[0026] Specifically, both ends of the left driven roller are rotatably connected to the second bearing seats 91 on the frame 1. The connecting plate 93 has an elliptical structure. Circular holes having the same diameter as the driven roller are formed at the center positions on both sides of the connecting plate 93. The driven roller can be positioned and fixed through the connecting plate 93, and the connecting plate 93 does not abut against the second conveyor belt 92 to prevent mutual friction. Since the right driven roller is movable relative to the frame 1, the second conveyor belt 92 is inclined to the right. When no yams are being conveyed, the second conveyor belt 92 abuts against the first conveyor belt 5. When yams are being conveyed, the right end of the second conveying structure 9 is lifted by the yams. When the left driven roller rotates, the right driven roller is driven to rotate through the second conveyor belt 92. When the yams move to the bottom end of the second conveyor belt 92, the second conveyor belt 92 squeezes the yams to move forward. When encountering yams of different diameters, the second conveyor belt 92 can tilt upward or downward so that the second conveyor belt 92 can abut against yams of different diameters, ensuring that the yams can reach the next slicing device in an arranged manner.

[0027] The length of the pressure roller 94 is the same as that of the second conveyor belt 92. The connecting shaft 95 extends to the upper end of the frame 1, and the frame 1 is provided with insertion holes relative to the position of the strip bar 97. In the initial state, the pressure roller 94 presses the second conveyor belt 92 downward due to gravity, and the spring 98 is not compressed. When passing through the Chinese yam, the Chinese yam jacks up the conveying structure 9 and the pressure roller 94, the pressure roller 94 rises, and the spring 98 is compressed. The Chinese yam is transmitted to the next structure, and the pressure roller 94 returns to the initial state. By setting the pressure roller 94 that can move up and down on the second conveyor belt 92, the stability of the Chinese yam transmission process is further ensured, the pressure on the second conveyor belt 92 is increased, and the efficiency during slicing is improved.

[0028] As Figure 3 and Figure 4 shown, one end of the transmission shaft of the driven roller on the left extends out of one end of the second bearing seat 91 and is fixedly connected with a first gear 910. A second gear 911 meshing with the first gear 910 is arranged below the first gear 910. A first sprocket 912 is fixedly connected to the inner side of the second gear 911. A connecting shaft extending from one side of the electric drum 4 on the right is fixedly connected with a second sprocket 20. A third sprocket 21 fixedly connected to the connecting shaft extending from the brush wheel 12 is arranged at the lower end of the second sprocket 20. The first sprocket 912, the second sprocket 20 and the third sprocket 21 in the same vertical horizontal plane are connected by a chain.

[0029] Specifically, the frame 1 is provided with a rotating shaft in the same vertical direction relative to the position of the driven roller. When the electric drum 4 is started, the second sprocket 20 drives the first sprocket 912 and the third sprocket 21 to rotate simultaneously through the chain. At this time, the brush wheel 12 rotates to clean the residue of the Chinese yam slices generated on the first conveyor belt 5, ensuring that it will not be blocked and always keeping the first conveyor belt 5 clean. The first sprocket 912 drives the second gear 911 to rotate. The second gear 911 meshes with the first gear 910, and the first gear 910 drives the conveying structure 9 to rotate. And the first conveyor belt 5 and the second conveyor belt 92 rotate in opposite directions (that is, the first conveyor belt 5 rotates clockwise and the second conveyor belt 92 rotates counterclockwise, so that the upper side of the first conveyor belt 5 and the lower side of the second conveyor belt 92 move in the same direction).

[0030] As Figure 1 shown, a plurality of soft bristles 13 are arranged on the brush wheel 12. The bristles 13 are made of nylon material. The nylon material has the advantages of durability, strong cleaning power and high-efficiency cleaning. The length of the bristles 13 is greater than the distance between the brush wheel 12 and the first conveyor belt 5, which can ensure that the residue on the first conveyor belt 5 is cleaned up.

The buttons for controlling operations are connected to the two control modules through wires. Buttons for operating the electric roller 4 are configured on the buttons. Through the button control instructions, the corresponding electric roller 4 can start, stop, run forward and reverse. The connection method and working principle of the power supply module, control module and electric roller 4 are all prior arts and will not be elaborated here.
