Description

Technical Field

[0001] This utility model relates to a feeding device, specifically an automatic mulberry leaf feeding device. Background Technology

[0002] Mulberry leaf feeding devices are mainly used for the automated transfer, sorting, and supply of materials in mulberry leaf processing (such as deep food processing). Their core function is to improve efficiency, reduce manual intervention, and ensure process stability. However, some technical and management deficiencies still exist in practical applications. The core function of automatic mulberry leaf feeding devices is to improve production efficiency and continuity, replacing manual handling and enabling the automatic transport of mulberry leaves from the raw material warehouse to processing equipment (such as sizing machines, mulberry leaf cutters, and frying lines), significantly shortening the production cycle. For example, the efficiency of automated mulberry leaf cutters can be more than 10 times that of manual operation. Furthermore, by precisely controlling the feeding quantity, speed, and position (such as uniform spraying of sizing liquid and synchronized feeding in frying lines), errors caused by manual operation are reduced, improving product qualification rates. Finally, the need for repetitive labor is reduced, alleviating labor shortage pressures. Integrated recycling systems (such as powder recovery and frying oil filtration) reduce raw material waste and extend the service life of auxiliary materials.

[0003] However, current mulberry leaf feeding devices have poor compatibility. Different mulberry leaf varieties (such as differences in leaf size and thickness) may lead to uneven sizing or material jamming, requiring frequent adjustments to equipment parameters. The operation and maintenance are complex, and debugging relies on professional technicians. Once the equipment is set up, it is difficult for operators to modify the program themselves. In case of failure, work must be stopped and repairs must be carried out. There are many points of failure. The automated system includes multiple modules such as mechanical, pneumatic, and control. Failure in any link (such as blockage of the vacuum feeder) may cause the entire line to stop. In addition, automated production lines require a large capital investment (such as modular production lines and precision control systems), which is difficult for small and medium-sized enterprises to afford. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide an automatic mulberry leaf feeding device.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: an automatic mulberry leaf feeding device, comprising a suction cup fixing plate and a plurality of evenly arranged suction cup devices installed on the lower surface of the suction cup fixing plate. A fixing connecting plate with an area smaller than the suction cup fixing plate is fixed above the suction cup fixing plate by a plurality of bolts, and the fixing connecting plate and the suction cup fixing plate are separated by the screw portion of the bolts. The fixing connecting plate is installed at the lower end of the horizontal and lifting device, so that the horizontal and lifting device drives each suction cup device to move horizontally and vertically at the same time.

[0006] Furthermore, the horizontal and lifting device consists of a Z-axis slide cylinder and an X-axis linear cylinder. The X-axis linear cylinder is fixed on a rectangular plate, which is fixed inside the top of the cuboid frame. The X-axis linear cylinder is arranged along the horizontal movement direction of the suction cup device. The fixed end of the Z-axis slide cylinder is fixed to the lower surface of the slide that is moved by the X-axis linear cylinder. The fixed connecting plate is fixed to the lower telescopic end of the Z-axis slide cylinder.

[0007] Furthermore, vertical guide rails are respectively set on both sides of the suction cup fixing plate, and the outer side of each vertical guide rail is set in the groove of the guide slider. The vertical guide rail slides up and down in the guide slider. The guide sliders on each side are slidably set on the horizontal guide rails on the inner side of the aluminum profile, so that the guide sliders on each side slide horizontally along the corresponding horizontal guide rails on the inner side of the aluminum profile. The outer side of the horizontal guide rails on the inner side of each aluminum profile is fixed to the left and right sides of the cuboid frame respectively.

[0008] Furthermore, the outer ends of the transverse guide rails on the inner side of each aluminum profile are respectively fixed with hydraulic dampers that face the guide sliders on the same side.

[0009] Furthermore, the suction cup device consists of an equal number of sponge suction cups and hollow telescopic rods. Each hollow telescopic rod vertically penetrates the suction cup fixing plate and is fixedly connected to the plate. The lower suction port of each hollow telescopic rod is covered with a sponge suction cup.

[0010] Furthermore, a mulberry leaf placement frame is provided on the inner table surface of the front side of the rectangular frame. The mulberry leaf placement frame has multiple square grooves for placing mulberry leaves, and a vibrator is also provided on the suction cup fixing plate to drive the suction cup fixing plate to shake.

[0011] Furthermore, the upper end of each suction cup device is fixedly connected to the air extraction end of the air exhaust module set on the lower surface of the fixed connecting plate via a hose, and the main air extraction end of the air exhaust module is fixedly connected to the air extraction end of an external vacuum pumping device via a hose.

[0012] Furthermore, the mulberry leaf placement frame is made of mesh sheet metal by stamping.

[0013] Furthermore, a placement frame limiting rod is fixed to the inner side of the mulberry leaf placement frame and the rectangular frame platform on the left and right sides.

[0014] Furthermore, a conveyor belt extending to the outside is installed in the rectangular frame on the side away from the mulberry leaf placement frame. The closed conveyor belt is driven by a geared motor, and the outer frame of the conveyor belt is supported by legs.

[0015] With the above settings, this utility model offers better compatibility with various product types. Multiple evenly arranged suction cups on the lower surface of the suction cup fixing plate, combined with a mulberry leaf placement frame, which has multiple square grooves for placing mulberry leaves, and a retractable hollow telescopic rod 202, facilitate contact between the sponge suction cups at its lower end and the mulberry leaves. This allows for easy adsorption and gripping of different mulberry leaf varieties (such as differences in leaf size and thickness), preventing uneven sizing or jamming, and eliminating the need for frequent adjustments to equipment parameters. The use of horizontal and lifting devices to drive the suction cups for leaf gripping not only reduces operation and maintenance difficulty, but also eliminates the need for specialized technicians during debugging. Once the equipment is set up, operators do not need to modify the program, effectively reducing the failure rate. In case of a failure, simply restarting to the initial position is sufficient, without downtime for repairs. The overall structure of this utility model is simpler and more practical. The automated system consists of simple mechanical, pneumatic, and control modules, resulting in good synergy, a lower failure rate, and preventing complete line downtime. Furthermore, it requires minimal capital investment, making it ideal for small and medium-sized enterprises. Attached Figure Description

Detailed Implementation

[0018] like Figure 1-3 As shown, an automatic mulberry leaf feeding device includes a suction cup fixing plate 1 and multiple suction cup devices 2 evenly arranged on the lower surface of the suction cup fixing plate 1. A fixing connecting plate 4 with an area smaller than the suction cup fixing plate 1 is fixed above the suction cup fixing plate 1 by multiple bolts 3, and the fixing connecting plate 4 is separated from the suction cup fixing plate 1 by the screw portion of the bolts 3. The fixing connecting plate 4 is installed at the lower end of a horizontal and lifting device 5, so that the horizontal and lifting device 5 drives each suction cup device 2 to move horizontally and vertically at the same time. A vibrator is also provided on the suction cup fixing plate 1 to drive the suction cup fixing plate 1 to shake.

[0019] Specifically: The horizontal and lifting device 5 consists of a Z-axis slide cylinder 501 and an X-axis linear cylinder 502. The X-axis linear cylinder 502 is fixed to a rectangular plate, which is fixed inside the top of the cuboid frame 6. The X-axis linear cylinder 502 is arranged along the horizontal movement direction of the suction cup device 2. The fixed end of the Z-axis slide cylinder 501 is fixed to the lower surface of the slide moved by the X-axis linear cylinder 502. The fixed connecting plate 4 is fixed to the lower telescopic end of the Z-axis slide cylinder 501. The Z-axis slide cylinder 501 and the X-axis linear cylinder 502... 02 is the existing technology. The x-axis linear cylinder 502 drives the z-axis slide cylinder 501 to move back and forth. The z-axis slide cylinder 501 drives the suction cup fixing plate 1 to move up and down, thereby ultimately driving each suction cup device 2 to move up and down and back and forth. This allows the suction cup device 2 to pick up mulberry leaves and send them to the next process to be placed down, thus completing the automatic feeding of mulberry leaves. Of course, the horizontal and lifting device 5 can also be replaced by a robotic arm, but the cost will inevitably increase. Therefore, the horizontal and lifting device 5 of this utility model is the most suitable in terms of existing technology, efficiency and cost.

[0020] Vertical guide rails 9 are respectively provided on both sides of the suction cup fixing plate 1. The outer side of each vertical guide rail 9 is set in the groove of the guide slider 7. The vertical guide rail 9 slides up and down in the guide slider 7. The guide slider 7 is slidably set on the transverse guide rail 8 on the inner side of the aluminum profile, so that the guide slider 7 on each side slides horizontally along the corresponding transverse guide rail 8 on the inner side of the aluminum profile. The outer side of the transverse guide rail 8 on the inner side of the aluminum profile is fixed to the left and right sides of the cuboid frame 6 respectively. The outer end of the transverse guide rail 8 on the inner side of the aluminum profile is fixed with a hydraulic damper 10 facing the guide slider 7 on the same side. Another hydraulic damper 10 is provided in the cuboid frame 6 on the other side, opposite to the z-axis slide cylinder 501. Thus, hydraulic dampers 10 for buffering are provided at both ends of the movement of the suction cup fixing plate 1.

[0021] The suction cup device 2 consists of an equal number of sponge suction cups 201 and hollow telescopic rods 202. The sponge suction cups 201 can be replaced by current Bernoulli suction cups. Each hollow telescopic rod 202 vertically penetrates the suction cup fixing plate 1 and is fixedly connected to the plate fixing plate 1. The lower suction port of each hollow telescopic rod 202 is covered by a sponge suction cup 201. The upper end of each suction cup device 2 (i.e., hollow telescopic rod 202) is fixedly connected to the air extraction end of the air exhaust module 12 set on the lower surface of the fixed connection plate 4 through a hose. The main air extraction end of the air exhaust module 12 is fixedly connected to the air extraction end of an external vacuum pump through a hose.

[0022] A mulberry leaf placement frame 11 is provided on the inner table surface of the front side of the rectangular frame 6. The mulberry leaf placement frame 11 has multiple square grooves for placing mulberry leaves. The mulberry leaf placement frame 11 is made of mesh sheet metal stamping and is composed of 18 small squares with a spacing of 2cm between each small square. Placement frame limiting rods 14 are fixed on the inner side of the mulberry leaf placement frame 11 and the left and right sides of the rectangular frame 6 table surface. A conveyor belt 13 extending to the outside is provided in the rectangular frame 6 on the side away from the mulberry leaf placement frame 11. The closed belt of the conveyor belt 13 is driven by a geared motor, and the outer frame of the conveyor belt 13 is supported by support legs.

[0023] The working principle of this utility model is as follows: The worker places the mulberry leaves filled with mulberry leaves into the machine frame 11, that is, into the limiting frame formed between the limiting rods 14 of the placement frame. The worker presses the start button, and the Z-axis slide cylinder 501 presses down. The suction cup picks up the mulberry leaves. Since a vibrator is preferably also provided, the excess mulberry leaves can be shaken off by the vibrator. (The thickness of the stacked mulberry leaves is controlled by the hollow telescopic rod 202.) At this time, the Z-axis slide cylinder 501 is raised, and the X-axis linear cylinder 502 moves forward, driving the suction cup device 2 to move forward. When it moves to the corresponding position and stops, the suction cup puts down the mulberry leaves, thereby realizing the automatic feeding of mulberry leaves by the suction cup device 2 after it has picked up the mulberry leaves.

[0024] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
