Description

Technical Field

[0001] The utility model belongs to the technical field of food processing equipment, and in particular relates to a continuous feeding type fixed-length cutting device for strip-shaped food materials. Background Art

[0002] Food refers to all kinds of finished products and raw materials for human consumption or drinking, as well as items that are traditionally both food and Chinese medicinal materials, but does not include items for therapeutic purposes, especially strip foods. In the production and processing of strip foods, food cutting devices are used.

[0003] In conventional food cutting devices, the cutting blade is positioned above the food and moves vertically relative to the food to cut it. However, food is typically transported on a continuous conveyor belt. Since the cutting blade is stationary relative to the conveyor belt, it may interfere with the food on the conveyor belt, causing the food to become misaligned relative to the conveyor belt. Utility Model Content

[0004] The utility model provides a continuous feeding type fixed-length cutting device for strip-shaped food, aiming to solve the problem in the prior art that food cutting devices easily interfere with the conveyed food when cutting food.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A continuous feeding type strip food fixed length cutting device comprises a frame, a conveyor for conveying food is provided on the frame, and a cutting component for cutting food on the conveyor is also provided on the frame;

[0007] The cutting assembly includes a cutting knife, the cutting knife is rotatably connected to the frame, and the linear speed of the cutting knife is equal to the conveying speed of the conveyor;

[0008] The conveyor includes a driving roller and a driven roller, a conveyor belt is provided between the driving roller and the driven roller, and the driving roller drives the conveyor belt to rotate;

[0009] The frame is further provided with a motor for driving the active roller. The motor includes an output shaft. The output shaft drives the active roller through a first transmission mechanism, and the output shaft drives the cutting knife through a second transmission mechanism.

[0010] A further improved solution: the first transmission mechanism is a belt transmission mechanism.

[0011] Based on the above technical solution: The belt drive mechanism has smooth transmission characteristics. Since the belt drive transmits motion and power through the friction between the belt and the pulley, its transmission process is relatively smooth, without obvious impact and vibration. This smooth transmission characteristic helps to reduce the shaking and deviation of the food during the cutting process, thereby reducing the risk of interference between the food and the cutting device. Secondly, the structure of the belt drive mechanism is relatively simple and easy to install and maintain. Compared with other transmission mechanisms, the belt drive mechanism does not require a complex lubrication system and sealing device, so its structure is more compact and lightweight. This simple structure not only reduces manufacturing costs, but also facilitates the installation and maintenance of the equipment.

[0012] A further improved solution: the active roller and the driven roller are both rotatably connected to the frame, a driving pulley is provided on the output shaft, a driven pulley is provided on the active roller, and a transmission belt is provided between the active pulley and the driven pulley.

[0013] Based on the above technical solution, a belt drive mechanism smoothly transmits power from the driving pulley to the driven pulley via a transmission belt, which in turn drives the driven roller. This transmission method provides cushioning and vibration absorption, making the power transmission process smoother and reducing food deviation and interference caused by shock and vibration. The belt drive mechanism has a relatively simple structure and occupies a small space, making the entire food cutting device more compact. Furthermore, since components such as the transmission belt and pulleys are relatively wear-resistant and easy to replace and maintain, maintenance costs and downtime are reduced.

[0014] A further improved solution: the transmission belt is a flat belt; or, the transmission belt is a V-belt; or, the transmission belt is a synchronous belt.

[0015] Based on the above technical solution, the selection of a drive belt type requires comprehensive consideration of factors such as the specific application scenario of the food cutting device, transmission accuracy requirements, cost budget, and ease of maintenance. To meet different needs and conditions, flat belts, V-belts, or synchronous belts can be selected to achieve the best transmission effect.

[0016] Further improved solution: the second transmission mechanism is a gear transmission mechanism.

[0017] Based on the above technical solution, the gear transmission mechanism features a constant transmission ratio and precise transmission. This accuracy ensures precise cutting during the food cutting process, avoiding uneven or poor cutting quality caused by transmission errors. Furthermore, the smoothness of the gear transmission helps reduce vibration and shock, protecting the food from damage.

[0018] A further improved solution: the second transmission mechanism includes a driving gear arranged on the output shaft and a driven gear driving the cutting knife to rotate, a reversing gear set is provided between the driving gear and the driven gear, the reversing gear set includes a main shaft rotatably connected to the frame, the lower end of the main shaft is provided with a lower gear meshing with the driving gear, and the upper end of the driving gear is provided with an upper gear meshing with the driven gear.

[0019] Based on the above technical solution, the reversing gear set is the core of the transmission mechanism. The meshing of the lower gear on the main shaft with the driving gear, and the meshing of the upper gear on the main shaft with the driven gear, achieves reversing power transmission. This design allows the driven gear to rotate in the desired direction, thus meeting the different requirements of the food cutting process.

[0020] A further improved solution: the driving gear, the driven gear, the upper gear and the lower gear are all bevel gears.

[0021] Based on the above technical solution, bevel gears, thanks to their unique tapered design, enable power transmission between two intersecting shafts. This design minimizes energy loss during transmission, thereby improving transmission efficiency. The conical meshing surfaces of bevel gears provide a more stable meshing compared to parallel shaft gears. When transmitting high torque or bearing heavy loads, bevel gears maintain a stable meshing state, reducing vibration and noise and improving overall system stability.

[0022] A further improved solution: the upper gear and the lower gear are both mounted on the main shaft via a key connection, and the driving gear is mounted on the output shaft via a key connection.

[0023] Based on the above technical solution: Key connections are a widely used connection method. Through the fit between the key and the shaft, and the key and the hub, they achieve a secure connection between the gear and the shaft. This connection method prevents the gears from loosening or falling out during power and torque transmission, thereby ensuring reliable and stable transmission. Key connections offer high mating precision, ensuring accurate alignment and transmission between the gear and shaft. This helps reduce transmission errors and vibration caused by excessive clearance, thereby improving transmission accuracy and overall system performance.

[0024] A further improved solution is as follows: the cutting knife is rotatably connected to the frame via a knife shaft, and the driven gear is mounted on the knife shaft via a key connection.

[0025] Based on this technical solution, the driven gear is securely mounted to the cutter shaft via a keyed connection, ensuring slip-free transmission between the gear and the cutter shaft during the transmission process. This robust connection improves transmission efficiency and reduces energy loss. The keyed connection maintains a fixed relative position between the driven gear and the cutter shaft, ensuring transmission system stability even at high speeds or under heavy loads. This helps reduce vibration and noise, enhancing the smoothness of the cutting process.

[0026] A further improved solution: the cutting assembly also includes a connecting frame, one end of the connecting frame is fixed to the knife shaft, the other end of the connecting frame is installed with the cutting knife, and the connecting frame is provided with a mounting groove for installing the cutting knife, and the cutting knife is fixed in the mounting groove by a screw.

[0027] Based on the above technical solution: The connecting frame acts as a bridge between the cutting knife and the blade shaft, and its stability directly affects the stability of the cutting knife during operation. By firmly fixing one end of the connecting frame to the blade shaft, it can be ensured that the cutting knife is not easily offset or shaken when rotating at high speeds or subjected to large cutting forces, thereby ensuring the accuracy and stability of cutting. The connecting frame is provided with a mounting slot for installing the cutting knife, which makes the installation position of the cutting knife more precise and controllable. By adjusting the size and position of the mounting slot, the contact angle and cutting depth between the cutting knife and the food can be conveniently adjusted to meet different cutting requirements.

[0028] The beneficial effects of the utility model are:

[0029] The utility model is achieved by designing the linear speed of the cutting knife to be equal to the conveying speed of the conveyor. This design ensures that the cutting knife can remain relatively still with the conveyed food when cutting the food, thereby avoiding interference and tearing caused by speed mismatch. The conveyor adopts a conveyor belt design between the active roller and the driven roller to achieve continuous feeding of food. This feeding method ensures the stability and continuity of the food during the cutting process and further reduces the possibility of interference. The motor drives the active roller through the first transmission mechanism and drives the cutting knife through the second transmission mechanism. This design makes the power transmission path more compact, reduces energy loss and improves transmission efficiency. By adjusting the installation position and angle of the cutting knife, and replacing the cutting knife with different shapes, sizes or materials, the device can adapt to the cutting needs of food of different types and specifications.

[0043] The transmission belt 8 is a flat belt; or, the transmission belt 8 is a V-belt; or, the transmission belt 8 is a synchronous belt.

[0044] Specifically: the second transmission mechanism is a gear transmission mechanism.

[0045] The second transmission mechanism includes a driving gear 9 provided on the output shaft 7 and a driven gear 10 driving the cutting knife 2 to rotate, a reversing gear set is provided between the driving gear 9 and the driven gear 10, and the reversing gear set includes a main shaft 11 rotatably connected to the frame 1, and the lower end of the main shaft 11 is provided with a lower gear 12 engaged with the driving gear 9, and the upper end of the driving gear 9 is provided with an upper gear 13 engaged with the driven gear 10.

Simultaneously, power from motor 6 is also transmitted to cutting blade 2 via the gear transmission mechanism.
