Description

Technical Field

[0001] This utility model relates to a packaging machine, specifically to a material feeding and stacking device. Background Technology

[0002] Some sheet-shaped packages need to be packed into cardboard boxes. These sheet-shaped packages are fed one by one onto a grid conveyor belt via a conveyor feeding device, and then transported forward to the boxing station for packaging. However, some products require multiple sheet-shaped packages to be packed into a single cardboard box. Current technology uses a rotary suction and release mechanism to pick up materials from a hopper and place them directly onto the grid conveyor belt. After multiple placements, the materials on the grid conveyor belt stack up. However, this structure has a technical problem: the drop point of the rotary suction and release mechanism is a certain distance from the grid conveyor belt. Due to this height, the sheet-shaped packages tend to float when falling, preventing them from landing stably within the grid area of ​​the grid conveyor belt. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, this utility model innovatively provides a material unloading and stacking device that can achieve stable material dropping after material stacking.

[0004] This material feeding and stacking device includes a frame, a hopper, a rotary suction and discharge mechanism, and a material stacking mechanism. The rotary suction and discharge mechanism is located in front of the hopper, and the material stacking mechanism is located below the rotary suction and discharge mechanism. The rotary suction and discharge mechanism includes a rotating disk, a rotating rod, and a vacuum nozzle. The vacuum nozzle is mounted on the rotating rod, and the rotating rod is mounted on the rotating disk. The rotating disk is rotatably mounted on the frame, and the rotating disk is driven by a rotary power source that drives the rotating disk to rotate. The material stacking mechanism includes a front baffle, a rear baffle, a middle partition, a material support plate, and a material support power source. The middle partition is located between the front baffle and the rear baffle to form several stacking hoppers. The material support plate is driven by the material support power source. The rear baffle has a through hole, and the material support power source can drive the material support plate through the through hole in the rear baffle into the stacking hopper.

[0005] The hopper includes a left hopper plate, a right hopper plate, a feeding belt, a front feeding wheel, a rear feeding wheel, and a feeding power source. The front feeding wheel and the rear feeding wheel can be rotatably installed between the left hopper plate and the right hopper plate. The feeding belt is wound around the front feeding wheel and the rear feeding wheel. The front feeding wheel or the rear feeding wheel is connected to the feeding power source. An upper stop and a lower stop are provided at the front end between the left hopper plate and the right hopper plate, and there is a discharge space between the upper stop and the lower stop.

[0006] The hopper is mounted on a hopper seat, which is vertically mounted on an adjusting seat via guide columns. The adjusting seat is equipped with a rotatable height adjusting screw, which is threadedly connected to the hopper seat.

[0007] The adjusting seat is slidably mounted on the guide rail of the base via a sliding block. The base is equipped with a rotatable front and rear adjusting screw, which is threadedly connected to the adjusting seat.

[0008] The upper stop is connected to the material stop bar, the material stop bar is connected to the upper crossbar, the upper crossbar is connected to the side bar, and the side bar is connected to the bin plate.

[0009] The side rod has a vertically extending side elongated hole, and the side rod is connected to the bin plate through the side elongated hole by a first bolt; the baffle rod has a front-to-back extending lower elongated hole, and the upper crossbar has a left-to-right extending upper elongated hole, and the baffle rod is connected to the upper crossbar through the upper elongated hole and the lower elongated hole by a second bolt.

[0010] According to the material feeding and stacking device provided by this utility model, by setting a material stacking mechanism below the rotary suction and discharge mechanism, the material is stacked before being fed, making the material fall more stably. Attached Figure Description

[0011] Figure 1 This is a perspective view of the present utility model; Figure 2 This is a structural diagram of the silo section; Figure 3 This is a partial schematic diagram of the silo; Figure 4 This is a schematic diagram of the rotary suction and discharge mechanism; Figure 5 This is a schematic diagram of the material stacking mechanism. Detailed Implementation

[0012] like Figure 1 As shown, this material feeding and stacking device includes a frame 1, a hopper 2, a rotary suction and discharge mechanism 3, and a material stacking mechanism 4. The rotary suction and discharge mechanism 3 is located in front of the hopper 2, and the material stacking mechanism 4 is located below the rotary suction and discharge mechanism 3. The material is stored in the hopper 2. The rotary suction and discharge mechanism 3 sucks the material out of the hopper 2 and places it into the material stacking mechanism 4. When the material in the material stacking mechanism 4 is stacked to a set quantity, the material stacking mechanism 4 controls the material to fall, and the material enters the grid conveyor belt below.

[0013] like Figure 3As shown, the rotary suction and discharge mechanism 3 includes a rotary disk 32, a rotary rod 31, and a vacuum nozzle 30. The vacuum nozzle 30 is mounted on the rotary rod 31 (the vacuum nozzle 30 is connected to a vacuum pump, which can generate negative pressure suction). The rotary rod 31 is mounted on the rotary disk 32. The rotary disk 32 is rotatably mounted on the frame 1. The rotary disk 32 is connected to the rotary power source 33 that drives the rotary disk 32 to rotate. Driven by the rotary power source 33, the rotary disk 32 rotates, causing the rotary rod 31 to revolve. First, the vacuum nozzle 30 comes to the front position of the hopper 2 to pick up the material, and then the vacuum nozzle 30 comes to the top of the material stacking mechanism 4 to discharge the material, allowing the material to be stacked in the material stacking mechanism 4.

[0014] like Figure 5 As shown, the material stacking mechanism 4 includes a front baffle 40, a rear baffle 41, several intermediate partitions 42, a support plate 43, and a support power source 45. Several intermediate partitions 42 are arranged between the front baffle 40 and the rear baffle 41 to form several stacking bins 46. The support plate 43 is connected to the support power source 45. The rear baffle 41 has perforations. When materials are to be stacked, the support power source 45 drives the support plate 43 to pass through the perforations of the rear baffle 41 and enter the stacking bin 46. After the materials enter the stacking bin 46, they are placed on the support plate 43. When the materials are stacked to a set quantity, the support power source 45 drives the support plate 43 to move backward. The support plate 43 no longer supports the materials, and the stacked materials fall onto the grid conveyor belt below. Because the stacked materials are relatively heavy and the falling distance is relatively short, the materials can fall stably onto the grid conveyor belt below.

[0015] like Figure 3 As shown, the hopper 2 includes a left hopper plate 20, a right hopper plate 21, a feeding belt (not shown), a front feeding wheel 28, a rear feeding wheel 29, and a feeding power source. The front feeding wheel 28 and the rear feeding wheel 29 are rotatably mounted between the left hopper plate 20 and the right hopper plate 21. The feeding belt is wound around the front feeding wheel 28 and the rear feeding wheel 29. Either the front feeding wheel 28 or the rear feeding wheel 29 is connected to the feeding power source. An upper stop 26 and a lower stop 27 are provided at the front end between the left hopper plate 20 and the right hopper plate 21, with a discharge space between them. Driven by the feeding power source, the feeding belt conveys the material in the hopper 2 forward, ensuring that the material at the very front always rests against the upper stop 26 and the lower stop 27, thus keeping the material at the very front at the suction point of the rotating suction and discharge mechanism 3.

[0016] In order to adjust the height of hopper 2, such as Figure 2As shown, the hopper 2 is mounted on the hopper seat 8. The hopper seat 8 is vertically mounted on the adjusting seat 7 via guide posts 9. The adjusting seat 7 is equipped with a rotatable height adjusting screw 11, which is threadedly connected to the hopper seat 8. By rotating the height adjusting screw 11, the hopper seat 8 can move up and down carrying the hopper 2, thereby adjusting the height of the hopper 2.

[0017] In order to adjust the front and rear position of hopper 2, such as Figure 2 As shown, the adjusting seat 7 is slidably mounted on the guide rail 6 of the base 5 via a sliding block. A rotatable front-to-back adjusting screw 10 is installed on the base 5, and the front-to-back adjusting screw 10 is threadedly connected to the adjusting seat 7. By rotating the front-to-back adjusting screw 10, the adjusting seat 7 moves back and forth on the guide rail 6, thus adjusting the front-to-back position of the hopper 2.

[0018] like Figure 3 As shown, the upper stop 26 is connected to the material stop rod 24, the material stop rod 24 is connected to the upper crossbar 23, the upper crossbar 23 is connected to the side rod 22, and the side rod 22 is connected to the bin plates (the bin plates are the left bin plate 20 and the right bin plate 21). This allows the upper stop 26 to be installed above the lower stop 27.

[0019] To facilitate adjustment of the position of the upper stop 26, such as Figure 3 As shown, the side rod 22 has a side elongated hole 220 extending vertically. The side rod 22 is connected to the bin plate by passing through the side elongated hole 220 with a first bolt. By moving the side rod 22 vertically, the vertical position of the upper stop 26 can be adjusted. The baffle rod 24 has a lower elongated hole 240 extending front to back, and the upper crossbar 23 has an upper elongated hole 230 extending left to right. The baffle rod 24 is connected to the upper crossbar 23 by passing through the upper elongated hole 230 and the lower elongated hole 240 with a second bolt. By moving the baffle rod 24 horizontally, the horizontal position of the upper stop 26 can be adjusted.
