Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of food processing equipment, and particularly relates to a trimming device for long strip food materials. BACKGROUND

[0002] Long strip food material cutting refers to cutting food materials with a relatively long length and a relatively narrow width. Such food materials usually have a long length during processing and are usually formed by a compression roller. When a compression roller is used to form long strip food materials, the two sides of the long strip food material usually have jagged edges. During processing, the jagged edges need to be cut off so that the long strip food material has a flat edge.

[0003] In the prior art, the jagged edges of long strip food materials are cut off by manual trimming. This trimming method has high labor intensity and low flatness. UTILITY MODEL CONTENTS

[0004] The utility model provides a trimming device for long strip food materials, which aims to solve the problem of high labor intensity and low flatness of operators during trimming of long strip food materials in the prior art.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme:

[0006] A trimming device for long strip food materials includes a rack. A conveyor for conveying food materials is arranged on the rack. The conveyor is a belt conveyor.

[0007] A trimming assembly for trimming food materials on the conveyor is further arranged on the rack. The trimming assembly includes a rotating shaft rotatably connected to the rack. Two ends of the rotating shaft are provided with cutters for trimming food materials on the conveyor. The cutters have a circular cross-sectional shape. A cutting knife for cutting food materials trimmed by the cutters is arranged on the cutters. The cutting knives are uniformly distributed along the circumferential direction of the cutters.

[0008] A collecting box for collecting trimmed food materials is further arranged on the rack. A guide assembly for guiding trimmed food materials to the collecting box is arranged on the rack.

[0009] The conveyor is driven by a first motor. The rotating shaft is driven by a second motor. The linear speed of the cutters is equal to the conveying speed of the conveyor.

[0010] Further improved scheme: The rack is provided with two upright columns for mounting the rotating shaft. The two upright columns are arranged at two ends of the rotating shaft. The two upright columns are each provided with an axle hole matched with the rotating shaft. Rolling bearings are arranged between the rotating shaft and the axle holes.

[0011] Based on the above technical solution: the use of rolling bearings greatly reduces the vibration of the rotating shaft, making the trimming process more stable. The precise installation of the shaft hole and the rolling bearing ensures the accuracy of the rotating shaft, thereby improving the flatness of the trimming. The stable shaft support structure makes the whole trimming device more reliable, reduces the downtime caused by the failure of the rotating shaft. The rolling bearing has a long service life and low friction loss, reducing the maintenance cost of the device.

[0012] Further improved scheme: two said cutters are arranged on the rotating shaft, and the distance between the two said cutters is equal to the width of the trimmed food material.

[0013] Based on the above technical solution: since the distance between the two cutters is accurately set to the width of the trimmed food material, it can ensure that the trimmed food material has consistent width size. Through the precise control of mechanization, the size error that may occur during manual trimming is avoided, and the trimming accuracy is improved.

[0014] Further improved scheme: the cutting edge of the cutter is flush with the cutting edge of the cutting knife, and the cutting edge of the cutting knife is perpendicular to the cutting edge of the cutter, and the cutter and the cutting knife are an integral structure.

[0015] Based on the above technical solution: the cutting edge of the cutter is flush with the cutting edge of the cutting knife, which ensures the synchronization of trimming and cutting actions. This means that the trimmed food material can be accurately cut to the predetermined length at the same time of trimming, without the need for additional cutting steps. The cutting edge of the cutting knife is perpendicular to the cutting edge of the cutter, which helps to achieve a clean and smooth cutting effect. The perpendicular cutting edge can penetrate the food material more effectively, reducing the resistance during cutting, thereby ensuring the flatness and smoothness of the cutting surface.

[0016] Further improved scheme: the conveyor includes a driving roller and a driven roller, both of which are rotationally connected to the rack, the first motor is rotationally connected to the rack through bolts, the first motor drives the driving roller through a transmission, and an annular belt is arranged between the driving roller and the driven roller.

[0017] Based on the above technical solution: the first motor drives the driving roller to rotate through the transmission, and the transmission can adjust the output speed of the motor to adapt to the conveying speed requirement of different food materials, ensuring the stability and continuity of the food materials during conveying. The annular belt arranged between the driving roller and the driven roller is responsible for carrying and conveying the food materials. The design of the annular belt allows the food materials to move smoothly on it, avoiding sliding or jumping of the food materials during conveying, thereby ensuring the accuracy and efficiency of trimming. The driving roller and the driven roller are both rotationally connected to the rack, which makes the structure of the conveyor part compact and occupies less space.

[0018] Further improved scheme: the guide assembly includes a conveyor belt, the conveying direction of the conveyor belt is perpendicular to the conveying direction of the conveyor, the food materials trimmed by the trimming assembly fall into the conveyor belt under the action of gravity, and all the food materials trimmed by the trimming assembly are conveyed to the collection box by the conveyor belt.

[0019] Based on the above technical scheme: the conveying direction of the conveyor belt is perpendicular to the conveying direction of the conveyor, such a layout ensures that the food materials trimmed by the trimming assembly can smoothly fall from the trimming area onto the conveyor belt. Due to the action of gravity, the food materials will naturally fall and move along the direction of the conveyor belt. The conveyor belt has the function of continuous conveying, which can continuously transport the trimmed food materials from the trimming area to the collection box, avoiding the accumulation and stagnation of food materials in the trimming area. All the food materials trimmed by the trimming assembly are conveyed to the collection box by the conveyor belt, realizing the centralized collection and processing of food materials. This facilitates subsequent utilization or disposal of food materials.

[0020] Further improved scheme: the guide assembly further includes a guide sheet, the guide sheet is arranged on the rack, and one end of the guide sheet extends above the conveyor, and the other end of the guide sheet extends directly above the conveyor belt.

[0021] Based on the above technical scheme: one end of the guide sheet extends above the conveyor, and the other end of the guide sheet extends directly above the conveyor belt, forming a clear food material guide path. When the food materials are trimmed by the trimming assembly, they will slide down along the inclined surface of the guide sheet under the action of gravity and fall onto the conveyor belt, ensuring that the food materials can accurately and orderly enter the conveying area. The design of the guide sheet helps to reduce the scattering and splashing of food materials during the sliding process, maintaining the cleanliness and orderliness of the working area.

[0022] Further improved scheme: the guide sheet is welded to the rack, or the guide sheet is fixed to the rack by screws.

[0023] Based on the above technical scheme: welding is a permanent connection method, once completed, the guide sheet and the rack will form a solid whole. This fixing method can ensure that the guide sheet will not loosen or fall off during long-term use, thereby maintaining its stability and durability. Since the welding fixing method has high stability, it reduces the maintenance needs caused by loosening or falling off. This helps to reduce the maintenance cost and downtime of the equipment. The screw fixing method allows the guide sheet to be easily installed and removed without the need for complex processes and equipment. This helps to reduce installation costs and time, and facilitates subsequent maintenance and replacement.

[0024] Further improved scheme: the guide piece has a gap with the upper surface of the conveyor, and the gap is not greater than 0.3mm.

[0025] Based on the above technical scheme: the gap design takes into account the vibration that may be generated during the operation of the device. The gap of not greater than 0.3mm helps to reduce noise and component loosening caused by vibration, thereby maintaining the stable operation of the device. Precise gap design reduces friction and wear between components, helping to extend the service life of the device.

[0026] Further improved scheme: the guide assembly further comprises a driving shaft rotatably connected to the rack and a driven shaft rotatably connected to the rack, and the two ends of the conveyor belt are sleeved on the driving shaft and the driven shaft respectively, and the rack is further provided with a third motor for driving the driving shaft.

[0027] Based on the above technical scheme: the third motor serves as a power source and drives the driving shaft to drive the rotation of the conveyor belt. This design ensures that the conveyor belt can operate stably and continuously, providing reliable power support for the conveying of food materials. The rotatable connection of the driving shaft and the driven shaft, and the stable connection between them and the rack, help to reduce the vibration and noise generated by the conveyor belt during operation, improving the overall performance of the device.

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

[0029] The utility model discloses a conveyor driven by the first motor and a trimming assembly driven by the second motor, realizes the automatic conveying and trimming of food materials. The operator only needs to place the food materials on the conveyor, and the device can automatically complete the trimming operation, greatly reducing the labor intensity of the operator. The cross-sectional shape of the cutter in the trimming assembly is circular, and the linear velocity is equal to the conveying speed of the conveyor. This design ensures that the cutter can trim the edges of the food materials stably and uniformly when contacting the food materials, thereby improving the flatness of trimming.

[0030] The setting of the collection box and the guide assembly can effectively guide and collect the trimmed food materials into the collection box. This not only avoids the scattering and waste of food materials, but also facilitates the subsequent utilization or disposal of food materials. The evenly distributed cutting knives on the cutter can cut the trimmed food materials while trimming. This design avoids the formation of long strip-shaped waste materials during trimming, making the trimmed food materials easier to collect and process. The action of the cutting knife makes the trimmed food materials present as small blocks or particles, which are easier to be guided by the guide assembly into the collection box, realizing the centralized collection and processing of waste materials. This not only improves the work efficiency, but also maintains the neatness and orderliness of the working area. BRIEF DESCRIPTION OF DRAWINGS
