Description

Technical Field

[0001] This utility model relates to the field of food packaging, and in particular to a food filling machine. Background Technology

[0002] As people's living standards improve, the variety of food is increasing. Existing foods include vacuum-packed foods and puffed foods. In terms of packaging, there are canned or boxed foods. Whether canned or boxed, the food needs to be weighed during packaging. The current packaging method is to weigh the food manually and then put it into the packaging box, which is inefficient. If a high-tech automated production line is used, the most important thing during filling is to ensure that the packaging box is placed directly below the discharge port. If it is misaligned, the food will scatter.

[0003] To address the aforementioned issues, a packaging machine has emerged. For example, Chinese Utility Model Patent CN219750226U discloses a food packaging machine, belonging to the field of packaging machines. It includes two side plates, symmetrically arranged, with an L-shaped cross-section. A main conveyor belt is mounted on one inner end of each side plate via bearings, and a secondary conveyor belt is mounted on the other inner end via bearings. A frame is positioned above the side plates, with a material bin on top of the frame. The frame is placed above the secondary conveyor belt. A drive bevel gear is coaxially mounted on the end of the main conveyor belt near the secondary conveyor belt, positioned on the outside of the side plates. A drive shaft A is mounted on the side of the side plate near the drive bevel gear via bearings. The production line is configured with two separate conveyor systems, a main conveyor driving the secondary conveyor to rotate. When the packaging box reaches the secondary conveyor belt, it is positioned directly below the discharge port. A mechanism prevents the secondary conveyor belt from moving, thus ensuring the packaging box does not move, facilitating filling. However, during the up-and-down movement of the auxiliary conveyor belt of the aforementioned packaging machine, the driven bevel teeth and the conveyor bevel teeth change from an engaged state to a non-engaged state. This places high demands on the stiffness coefficients of springs B and A, requiring regular replacement and resulting in high maintenance costs for the packaging machine. Therefore, a food filling machine is proposed to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a food filling machine.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a food filling machine, comprising a main conveyor belt, a secondary conveyor belt, a mounting frame, a material cylinder, and two side plates. The two side plates are spaced apart, with the main conveyor belt positioned between them. The mounting frame is mounted on the upper end of the side plates, and the material cylinder is mounted on the mounting frame with a valve at its discharge end. The secondary conveyor belt is located below the material cylinder. Both the main and secondary conveyor belts are driven by a drive mechanism. The machine also includes a first vertical rod, a second vertical rod, a touch switch, a collection bucket, a stop bar, and a torsion spring. The mounting frame has an opening... The system includes an installation slot, in which the first and second vertical rods are fixed. A stop rod is rotatably mounted on the first vertical rod via a bearing. A torsion spring is fixedly sleeved on the second vertical rod, with one end abutting against the stop rod. A touch switch is located on the side wall of the installation slot. The touch switch and the drive mechanism are electrically connected to the controller. The secondary conveyor belt is slidably mounted between the two side plates via a sliding assembly. The collection bucket is placed on the main conveyor belt and has a notch adapted to the stop rod.

[0007] As a preferred embodiment of this utility model, the sliding assembly includes two sliders and a return spring. Each of the two side plates is provided with a sliding groove. The sliders slide up and down in the corresponding sliding grooves. The two ends of the secondary conveyor belt are respectively connected to the two sliders. One end of the return spring is connected to the slider and the other end is connected to the bottom wall of the sliding groove.

[0008] In a preferred embodiment of this invention, the notch is located at the top of the collection bucket.

[0009] As a preferred embodiment of this utility model, it further includes reinforcing ribs, which are fixedly connected to the mounting frame and the side plate respectively.

[0010] As a preferred embodiment of this utility model, it also includes a protective pad, which is disposed in the mounting groove on the side away from the touch switch.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention relates to a food filling machine. An empty collection bin is placed on the main conveyor belt. The main and auxiliary conveyor belts are driven by a drive motor, transporting the collection bin to the auxiliary conveyor belt. At this point, the collection bin pushes a stop lever until it contacts a touch switch. The touch switch transmits this signal to the controller, which then stops one of the drive motors. The auxiliary conveyor belt stops transporting food, and the collection bin stops directly below the discharge end of the material cylinder. Food is then fed into the collection bin through the material cylinder. As the amount of food in the collection bin increases and its weight increases, the collection bin gradually moves downwards under the action of a sliding component until the stop lever moves to the notch in the collection bin. Under the action of a torsion spring, the stop lever passes through the notch and leaves the touch switch. The touch switch transmits this signal to the controller, which then stops one of the drive motors. The auxiliary conveyor belt continues transporting food until the collection bin completely leaves the auxiliary conveyor belt, thus completing the food filling process. Attached Figure Description

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0034] Figure 1-3 This utility model provides a food filling machine, including a main conveyor belt 1, a secondary conveyor belt 2, a mounting frame 3, a material cylinder 4, and two side plates 5. The two side plates 5 are spaced apart. The main conveyor belt 1 is located between the two side plates 5. The mounting frame 3 is located at the upper end of the side plates 5. The material cylinder 4 is located on the mounting frame 3, and a valve 14 is provided at its discharge end. The secondary conveyor belt 2 is located below the material cylinder 4. Both the main conveyor belt 1 and the secondary conveyor belt 2 are driven by a drive mechanism. The machine also includes a first vertical rod 6, a second vertical rod 7, a touch switch 8, a collection bucket 9, and a stop bar 10. The torsion spring 15 and the mounting bracket 3 have mounting grooves. The first vertical rod 6 and the second vertical rod 7 are both fixed in the mounting grooves. The stop rod 10 is rotatably mounted on the first vertical rod 6 through a bearing. The torsion spring 15 is fixedly sleeved on the second vertical rod 7, and one end of it abuts against the stop rod 10. The touch switch 8 is located on the side wall of the mounting groove. The touch switch 8 and the drive mechanism are electrically connected to the controller. The auxiliary conveyor belt 2 is slidably mounted between the two side plates 5 through a sliding assembly. The collection bucket 9 is placed on the main conveyor belt 1 and has a notch that matches the stop rod 10.

[0035] In this embodiment, the drive mechanism includes drive motors and transmission shafts. Both drive motors are mounted on one side plate via mounting bases. The output shafts of the two drive motors are horizontally positioned and coaxially connected to their corresponding transmission shafts. One end of the transmission shaft furthest from its corresponding drive motor is coaxially connected to the drive roller of the main conveyor belt 1; the other end of the transmission shaft furthest from its corresponding drive motor is also coaxially connected to the drive roller of the auxiliary conveyor belt 2. When the drive motors are started, their output torque is transmitted to the transmission shafts via a coupling. The rotation of the transmission shafts drives the drive rollers of the main conveyor belt 1, thereby driving the main conveyor belt 1 to transport materials. The transmission shafts also drive the drive rollers of the auxiliary conveyor belt 2 to rotate, thereby driving the auxiliary conveyor belt 1 to transport materials. An empty collection bucket 9 is placed on the main conveyor belt 1. The main conveyor belt 1 and the auxiliary conveyor belt 2 are transported by the drive motor, thus transporting the collection bucket 9 to the auxiliary conveyor belt 2. At this time, the collection bucket 9 pushes the stop lever 10 until the stop lever 10 contacts the touch switch 8. The touch switch 8 transmits this signal to the controller (the controller is an STM32 microcontroller). The controller controls one of the drive motors to stop working. At this time, the auxiliary conveyor belt 2 stops transporting, and the collection bucket 9 stops directly below the discharge end of the material cylinder 4. Food is transported into the collection bucket 9 through the material cylinder 4. As the amount of food in the collection bucket 9 gradually increases and the weight gradually increases, the collection bucket 9 will gradually move downward under the action of the sliding component until the stop lever 10 moves to the notch of the collection bucket 9. Under the action of the torsion spring 15, the stop lever 10 will pass through the notch and leave the touch switch 8. The touch switch 8 will transmit this signal to the controller, and the controller controls one of the drive motors to continue working. At this time, the auxiliary conveyor belt 2 transports normally until the collection bucket 9 completely leaves the auxiliary conveyor belt 2, thus completing the food filling.

[0036] Specifically, the sliding assembly includes two sliders 111 and a return spring 112. Both side plates 5 are provided with grooves 113. The sliders 111 slide up and down in the corresponding grooves 113. The two ends of the secondary conveyor belt 2 are connected to the two sliders 111 respectively. One end of the return spring 112 is connected to the slider 111 and the other end is connected to the bottom wall of the groove 113.

[0037] As the collection bucket 9 above the secondary conveyor belt 2 gradually increases in weight, the return spring 112 is compressed, and the slider 111 moves downward within the slide groove 113.

[0038] Preferably, the notch is located at the top of the collection bucket 9.

[0039] The higher position of the notch allows more food to be filled into the collection bin 9.

[0040] Preferably, it also includes a reinforcing rib 12, which is fixedly connected to the mounting bracket 3 and the side plate 5 respectively.

[0041] The reinforcing rib 12 can improve the strength of the joint surface between the mounting bracket 3 and the side plate 5.

[0042] Preferably, it also includes a protective pad 13, which is disposed in the mounting groove on the side away from the touch switch 8.

[0043] The anti-slip pad 13 can protect the stop bar 10 and prevent the stop bar 10 from colliding with the side wall of the mounting groove when it is reset under the action of the torsion spring 15.

[0044] The working principle of this utility model:

[0045] When the drive motor is started, its output torque is transmitted to the transmission shaft through the coupling. The rotation of the transmission shaft can drive the drive roller of the main conveyor belt 1 to rotate, thereby driving the main conveyor belt 1 to transport. The transmission shaft can also drive the drive roller of the auxiliary conveyor belt 2 to rotate, thereby driving the auxiliary conveyor belt 1 to transport. An empty collection bucket 9 is placed on the main conveyor belt 1. The main conveyor belt 1 and the auxiliary conveyor belt 2 are transported by the drive motor, thus transporting the collection bucket 9 to the auxiliary conveyor belt 2. At this time, the collection bucket 9 pushes the stop lever 10 until the stop lever 10 contacts the touch switch 8. The touch switch 8 transmits this signal to the controller, and the controller controls one of the drive motors to stop working. At this time, the auxiliary conveyor belt 2 stops transporting, and the collection bucket 9 stops directly below the discharge end of the material cylinder 4. Food is conveyed into the collection bucket 9 through the material cylinder 4. As the amount of food in the collection bucket 9 gradually increases and the weight gradually increases, the return spring 112 is compressed, and the slider 111 moves downward in the slide 113. The collection bucket 9 also gradually moves downward until the stop lever 10 moves to the notch of the collection bucket 9. Under the action of the torsion spring 15, the stop lever 10 will pass through the notch and leave the touch switch 8. The touch switch 8 will transmit this signal to the controller, and the controller controls one of the drive motors to continue working. At this time, the auxiliary conveyor belt 2 transports normally until the collection bucket 9 completely leaves the auxiliary conveyor belt 2, thus completing the food filling.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
