Description

Technical Field

[0001] The utility model relates to a cutting device, in particular to an adaptive broccoli continuous slicing device, belonging to the technical field of vegetable cutting. Background Art

[0002] With people's continuous pursuit of healthy diet, the demand for vegetables has increased significantly. Coupled with the growing demand for vegetable-related products in the global market, the scale of the broccoli market has expanded rapidly. In terms of broccoli dicing, most of them currently use manual dicing, which is inefficient and has the risk of injury to operators. The mechanization degree of broccoli dicing is low. Although there are many types of broccoli cutters on the market, the height of the cutting blades on most broccoli cutters cannot be adjusted, that is, a fixed-size dicing method is adopted. This method is only effective for broccoli dicing within a certain size range, but due to the wide variety of broccoli varieties and different sizes, the fixed-size dicing method cannot adapt well to the changes in broccoli varieties and sizes. After dicing, there will be more large-sized flower pieces, which cannot meet the market demand well. Although an adaptive broccoli continuous dicing device with the publication number CN207224099U solves the problem of uneven dicing well, the equipment is more complicated and inefficient. Summary of the invention

[0003] The purpose of the utility model is to provide an adaptive broccoli continuous slicing device in order to solve the above problems.

[0004] The utility model achieves the above-mentioned purpose through the following technical scheme: an adaptive broccoli continuous slicing device, comprising:

[0005] The conveying device is provided with a reduction motor, a chain transmission device, a conveying chain plate and an intermittent mechanism. The driving sprocket of the chain transmission device is connected to the reduction motor, and its driven sprocket is coaxial with the driving wheel of the intermittent mechanism. The intermittent mechanism is provided with a transmission gear and a locking pair. The driving wheel of the transmission gear is an incomplete gear, and the driven wheel is a complete gear. The locking pair is composed of a concave locking pair and a convex locking pair, which are respectively fixed on the transmission shafts of the driven wheel and the driving wheel through a key connection, and are tightly fitted with the driving wheel and the driven wheel during installation. The conveying chain plate adopts a roller chain plate conveyor belt, on which a plurality of hollow truncated cone faceplates are installed.

[0006] The cutting actuator is divided into two parts: linear motion and circular motion. It adopts the superposition of linear motion in the vertical direction and circular motion of the spherical tool opening and closing to change the cutting trajectory of the spherical tool. The linear motion part is provided with a servo motor and a rack-and-pinion mechanism. The servo motor is located above the rack-and-pinion mechanism and is used to drive the rack-and-pinion mechanism to realize the advancement and retraction of the spherical tool, and cooperate with the six-bar mechanism to complete the change of the cutting trajectory of the spherical tool. The circular motion part is provided with a cylinder, a six-bar mechanism, and a spherical tool. The cylinder is connected to the six-bar mechanism to drive the six-bar mechanism to move. The two spherical blades are symmetrically installed at two hinge points. The tension and thrust transmitted by the non-edge pin shaft cause the two blades to rotate around their hinge points respectively, thereby realizing the opening and closing of the two blades.

[0007] The visual sensor, which is threaded onto the side of the rack and pinion frame, is used to detect and identify the diameter of the broccoli.

[0008] Preferably, when the speed of the linear motion in the vertical direction increases, the opening of the spherical tool cutting trajectory curve decreases accordingly, that is, only the linear speed in the vertical direction and the position where the spherical tool starts cutting need to be controlled to achieve cutting of broccoli of different sizes.

[0009] Preferably, a linear bearing is used in conjunction with a cylindrical guide rail to limit the horizontal freedom of the rack, thereby enhancing the stability of the rack and pinion mechanism.

[0010] Preferably, the rack and pinion mechanism drives the entire six-bar mechanism to perform linear motion in the vertical direction, and the six-bar mechanism is driven by a cylinder, thereby driving the spherical tool to perform circular motion, so that the blade can achieve a cutting trajectory that approximates a quadratic curve.

[0011] Preferably, the locking pair is located at a toothless position of the incomplete gear. When the driving wheel and the driven wheel are in gear meshing, the broccoli is conveyed. When the driving wheel rotates to the toothless position, the locking pair cooperates to limit the rotation of the driven wheel, so that the conveyor belt stops and the broccoli is cut into pieces.

[0012] Preferably, the visual sensor can detect and identify the diameter of the broccoli buds, interact through the PLC inside the device, and cooperate with the cutting actuator to complete the cutting work within the static time of the truncated table flower disk.

[0013] The beneficial effect of the utility model is that the linear motion in the vertical direction and the circular motion of the spherical tool opening and closing are superimposed to realize the change of the cutting trajectory of the spherical tool, that is, the cutting of broccoli of different sizes can be realized by only controlling the linear speed in the vertical direction and the position where the spherical tool starts cutting, which effectively solves the problem of different sizes of broccoli cut from different varieties caused by the fixed size cutting method, is more adaptable to the changes in the varieties and sizes of broccoli, realizes the stable cutting of broccoli, improves the cutting efficiency, and better meets the market demand.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model, but it is not intended to limit the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0020] See attached Figure 1 To Attachment Figure 4As shown, the adaptive broccoli continuous dicing device mainly includes a dicing actuator, a conveying device, and a visual sensor. Specifically, the driving sprocket of the chain transmission device 2 is connected to the reduction motor 1, and its driven sprocket is coaxial with the driving wheel 6 of the intermittent mechanism. The intermittent mechanism is provided with a transmission gear and a locking pair. The driving wheel 6 of the transmission gear is an incomplete gear, and the driven wheel 3 is a complete gear. The locking pair is divided into a concave locking pair 4 and a convex locking pair 5. The visual sensor 9 in the actuator is threadedly connected to the side of the rack 10 frame, the servo motor 11 drives the rack 10, and drives the entire six-bar mechanism to move linearly in the vertical direction. The cylinder 8 drives the six-bar mechanism to move in an arc. The spherical tool 7 is composed of two spherical blades, which are symmetrically installed at two hinge points. The conveying chain plate 12 is equipped with a plurality of hollow truncated table flower discs 13 for transporting broccoli.

[0021] Specifically, the cutting trajectory of the spherical cutter 7 is an approximate quadratic curve, and is a quadratic curve under ideal conditions.

[0022] Specifically, the female locking pair 4 and the male locking pair 5 are respectively fixed on the transmission shafts of the driven wheel 3 and the driving wheel 6 through key connections.

[0023] Specifically, a linear bearing is used in conjunction with a cylindrical guide rail to limit the horizontal degree of freedom of the rack, thereby enhancing the stability of the gear rack 10. Example

[0024] See attached Figure 1 To Attachment Figure 4 As shown, the self-adaptive broccoli continuous slicing device has an intermittent mechanism working process as follows: when the driving wheel 6 and the driven wheel 3 are in gear meshing, the broccoli is conveyed; when the driving wheel 6 rotates to a toothless position, the locking pair cooperates to limit the rotation of the driven wheel 3, so that the conveyor belt stops and the broccoli is cut. Example

[0025] See attached Figure 1 To Attachment Figure 4As shown, the self-adaptive broccoli continuous dicing device has the following general working process: the reduction motor 1 drives the active sprocket in the chain transmission device 2 to rotate, and the driven sprocket is driven to rotate synchronously through the transmission chain, and the driven sprocket drives the active wheel 6 in the intermittent mechanism to rotate through the transmission shaft, and when the active wheel 6 is engaged with the driven wheel 3, the transmission shaft drives the conveying chain plate 12 to rotate slowly, and when the visual sensor 9 recognizes that the broccoli cone flower disk 13 placed on the conveying chain plate 12 reaches the dicing position, it drives the active wheel 6 in the intermittent mechanism to end the gear meshing with the driven wheel 3, and the driven wheel 3 is kept stationary through the locking pair. In this process, the broccoli dicing actuator performs broccoli dicing. The broccoli cutting process, that is, the visual sensor 9 transmits the broccoli bract diameter data to the PLC, thereby controlling the servo motor 11 to drive the gear rack 10 to initially adjust the linear speed in the vertical direction and the initial position of the spherical tool 7, and then the gear rack 10 drives the six-bar mechanism to move in a straight line, and at the same time the cylinder 8 pushes the six-bar mechanism to move, thereby driving the spherical tool 7 to perform a cutting trajectory that approximates a quadratic curve, to achieve broccoli cutting. After the cutting is completed, the active wheel 6 in the intermittent mechanism continues to mesh with the driven wheel 3, and again drives the conveying chain plate 12 to rotate slowly, and the next broccoli cutting process is performed, thereby achieving continuous and smooth broccoli cutting.
