An inclined spring sheet is arranged between the vibration plate bottom plate 23 and the vibration plate vibration mechanism 22. The vibration plate bottom plate 23 and the vibration plate cylinder wall 41 are used to receive the paper pad 1 material poured down from the vibration screen 4. The material height of the paper pad 1 in the vibration plate silo is detected in real time by the dual laser ranging mechanism 17, and the total material height of the paper pad 1 is automatically controlled to be kept within a certain range. The inner wall of the vibration plate cylinder wall 41 is provided with a spiral upward vibration plate silo inner material channel 24. The pulse electromagnet in the vibration plate vibration mechanism 22 generates power on and off under the action of current, so that the vibration plate bottom plate 23 vibrates vertically up and down. Due to the inclination of the spring sheet connected to the vibration plate bottom plate 23, the vibration plate bottom plate 23 will make a torsional pendulum vibration in one direction. Due to this vibration, the paper pad 1 in the vibration plate silo will continuously move forward and gradually rise along the inner material channel 24 of the vibration plate silo. In this process, the paper pad 1 will continuously adjust its posture and spread evenly. The width of the inner channel 24 of the vibrating disk silo is limited to accommodate only one paper cushion block 1, so the paper cushion blocks 1 can only be discharged in a row on the inner channel 24 of the vibrating disk silo.

[0029] The outer wall of the vibration disk barrel wall 41 is provided with a spiral downward vibration disk material bin outer channel 1 25 and a vibration disk material bin outer channel 2 26. The discharge port of the vibration disk material bin inner channel 24 is respectively connected with the feed ports of the vibration disk material bin outer channel 1 25 and the vibration disk material bin outer channel 2 26. The connection position is provided with a material change channel baffle 27. The discharge ports of the vibration disk material bin outer channel 1 25 and the vibration disk material bin outer channel 2 26 are connected with the vibration disk outlet channel 31. Double channels are provided on the outer wall of the vibration disk barrel wall 41. The vibration disk material bin outer channel 2 26 is suitable for paper pads 1 with the same length and width. The installation position of the material change channel baffle 27 is adjusted by bolts as needed, so that one of the vibration disk material bin outer channel 1 25 and the vibration disk material bin outer channel 2 26 is closed and the other is opened. A paddle 28 is provided at the outlet of the inner channel 24 of the vibrating disk silo. By setting the height of the paddle 28, the paddle 28 can break up the paper cushion blocks 1 vibrated out from the bottom plate 23 of the vibrating disk. A paddle 29 is respectively installed at the feed inlet of the outer channel 25 of the vibrating disk silo and the outer channel 26 of the vibrating disk silo. By setting the height of the paddle 29, it is ensured that the paper cushion blocks 1 are transported outward in a single layer. A paddle 3 30 is respectively installed at the discharge outlet of the outer channel 25 of the vibrating disk silo and the outer channel 26 of the vibrating disk silo. By setting the height of the paddle 3 30, the paper cushion blocks 1 with the wrong direction are pushed out and returned to the vibrating disk silo, meeting the requirement that the direction of the paper cushion blocks 1 is 100% correct. Because the arc structure of the paper cushion block 1 has a small processing arc, especially when the length and width of the paper cushion block 1 are the same, there may still be errors in adjusting the direction of the paper cushion block 1 only by relying on the specially designed paddle 1 28 and paddle 2 29, so a paddle 30 is added near the vibrating plate outlet channel 31. The paddle 30 blocks the paper cushion block 1 with the wrong height size, and uses the arc to guide the paper cushion block 1 to fall back to the bottom of the vibrating plate bin, and vibrate it again to participate in the screening again. Only the paper cushion block 1 with the correct height can pass.

[0030] The discharge end of the vibrating plate outlet channel 31 is connected to the front end (feeding end) of the direct vibration conveying mechanism 8. The direct vibration conveying mechanism 8 includes a straight vibration strip plate 32. The middle part of the straight vibration strip plate 32 is fixedly mounted on the straight vibration vibration mechanism 35. The cross section of the straight vibration strip plate 32 is L-shaped. A straight vibration side baffle plate 33 with a boss structure is integrally formed on one side of the straight vibration strip plate 32. A push plate 34 is movably mounted on the other side of the straight vibration strip plate 32. The push plate 34 and the straight vibration side baffle plate 33 cooperate with the upper surface of the straight vibration strip plate 32 to form a slideway for the paper supply pad 1 to move. The distance between the push plate 34 and the straight vibration side baffle plate 33 can be adjusted to accommodate paper pads 1 of different widths. A full material detection mechanism 40 is fixedly mounted on the outer rear end of the straight vibration strip plate 32, and a lack of material detection mechanism 39 is fixedly mounted on the outer front end of the straight vibration strip plate 32. An L-shaped height paddle 37 is provided above the front end of the straight vibration strip 32. The spacing between the horizontal plate of the height paddle 37 and the straight vibration strip 32 can be adjusted to accommodate paper pads 1 of different thicknesses. At the same time, the height paddle 37 can push down the upper layer of individual double-layer paper pads 1 without forming material accumulation. A material pushing cylinder 36 and a laser rangefinder 38 are provided on both sides of the straight vibration strip 32 near the height paddle 37, respectively. A notch is provided at the push rod of the corresponding push cylinder 36. The laser rangefinder 38 can identify the arc direction of the paper pad 1 and whether there is material accumulation. The measured distance value of the laser rangefinder 38 should be approximately equal to the arc angle radius. If the measured distance value is close to zero, it means that there is no arc, indicating that it is a paper pad 1 with the wrong direction. The push rod of the push cylinder 36 pushes the paper pad 1 out. An inclined material guide slide is provided below this position, and the pushed paper pad 1 falls back into the bottom plate 23 of the vibration plate. The full material detection mechanism 40 is linked with the laser rangefinder 38. When the full material detection mechanism 40 detects that there is material and the laser rangefinder 38 does not detect a sudden change in data (pad gap) within a certain period of time, it means that the material is full, and the control system controls the vibration plate 6 to stop running. When the lack of material detection mechanism 39 and the laser rangefinder 38 do not detect the paper pad 1 within a certain period of time, it means that there is a lack of material. When there is a lack of material, the control system controls the vibration plate 6 to automatically start feeding.

[0031] The vibration disk 6 and the direct vibration conveying mechanism 8 are used in conjunction with each other. The vibration disk 6 is used to sort the paper pads 1, and the direct vibration conveying mechanism 8 is used to act as a buffer area and detect the paper pads 1. The direct vibration conveying mechanism 8 can also provide a stable and accurate feeding position. Under the action of the vibration disk 6, the paper pads 1 slide out along the spiral chute in turn, and are arranged in length and width according to the requirements of the drawing. The paper pads 1 are sent to the bottom of the glue spraying mechanism through the direct vibration conveying mechanism 8, and the glue spraying mechanism sprays glue on the paper pads 1 arranged in the moving slide between the push plate 34 and the direct vibration side baffle 33. The frame of the vibration disk 6 and the frame of the glue spraying mechanism are independent of each other to avoid the vibration of the vibration disk 6 from having a negative impact on the automatic glue spraying. A margin is left around the paper pad 1, because the glue will extend to the periphery when pressed, and the vibration of the direct vibration conveying mechanism 8 will not have much effect on the glue spraying. Embodiment 2

[0032] According to different production process requirements, the length a, width b and height c of the paper cushion block 1 are all variable values, such as Figure 10-17 As shown, the second embodiment is based on the first embodiment. In order to flexibly adapt to the different sizes of the paper cushion block 1 that often change, ensure that the paper cushion block 1 reaches 100% accuracy, and at the same time, in order to accurately push the paper cushion block 1 sprayed with glue onto the electric turntable, a positioning and pushing mechanism is set at the discharge end (rear end) of the direct vibration conveying mechanism 8. The positioning and pushing mechanism includes components such as the middle plate 1 44 and the middle plate 2 46, as well as two sets of servo motors and linear modules. The three variables of the length a, width b and height c of the paper cushion block 1 are adjusted mechanically and electrically to form precise positioning. Only the paper cushion block 1 with correct three variables can be pushed onto the electric turntable through the positioning and pushing mechanism. The pushing line speed beat of the positioning and pushing mechanism matches the line speed of the electric turntable to form a reciprocating feeding with a certain beat.

[0033] A circular screw hole is provided on one side of the upper surface of the rear end of the straight vibration long strip plate 32 on the same side as the straight vibration side baffle plate 33, and the intermediate plate 1 44 and the positioning plate 1 43 are installed at the circular screw hole by bolts.

A slideway for the paper supply cushion block 1 to pass through is formed between the positioning plate 1 43 and the positioning plate 2 45. Since the positioning plate 2 45, the middle plate 2 46 and the straight vibration strip plate 32 are connected by waist-shaped screw holes, the positions of the positioning plate 2 45 and the middle plate 2 46 can be fine-tuned along the width direction of the straight vibration strip plate 32, thereby changing the width of the slideway for the paper supply cushion block 1 to adapt to paper cushion blocks 1 of different sizes.

[0034] A mounting base plate 47 is provided below the rear end of the straight vibration strip 32, and the mounting base plate 47 is fixedly mounted on the bracket of the positioning and pushing mechanism (the bracket is not shown in the figure). The upper surface of the mounting base plate 47 can be processed with steps according to the installation requirements to adapt to the different heights of various components. A sliding module 48 is fixedly installed on the left side of the upper surface of the mounting base plate 47, and the sliding module 48 includes components such as a slider 481, a lead screw slide rail 482 and a motor 483.

When the slide 50 moves and adjusts to adapt to the length a of different paper pads 1, there are always constraints on both sides of the feeding track, and the paper pads 1 will not tilt or fall off the slideway. The length a of the paper pad 1 is a parameter value that changes frequently, while the width b and height c do not change frequently. Therefore, the width b and height c are both manually adjusted. The length a may need to be adjusted more than three times in one shift. By setting up the slide 50, the set value option corresponding to the length a can be directly selected through the control system to easily adjust it.

Embodiment 3

[0043] The control method of the automatic feeding device for paper cushion blocks according to the second embodiment of the present invention comprises the following steps: The paper cushion block 1 is sent to the vibrating screen 4 by the bucket elevator 3, and the fine impurities therein are screened out by the vibrating screen 4. The fine impurities are collected together by the negative pressure dust removal mechanism 5 through the sieve holes under the combined action of gravity and negative pressure suction. The clean paper cushion block 1 after the impurities are removed falls into the vibrating plate 6. The paper pad 1 material is put into the large hopper (storage bin) at the bottom of the bucket elevator 3 at one time. The PLC control system controls the linkage start and stop of multiple devices, and detects the material level in the vibration plate 6 in real time. When the material level reaches a low level, the bucket elevator 3 starts automatically to feed the raw materials into the vibration screen 4; the material situation in the vibration screen 4 is automatically monitored in real time. When the vibration screen 4 is full of material, the bucket elevator 3 stops, and the vibration screen 4 continues to vibrate for a certain period of time (the time can be set arbitrarily according to the cleanliness of the raw material) to ensure that the material debris and dust have been cleaned by the negative pressure dust removal mechanism 5, and the paper pad 1 is automatically put into the vibration plate 6; when the vibration screen 4 automatically detects that there is no material, the bucket elevator 3 is started to feed the material, and the paper pad 1 is purified and put into the vibration plate 6 after reciprocating circulation; when the vibration plate 6 is full of material, the bucket elevator 3, the vibration screen 4 and the negative pressure dust removal mechanism 5 do not put any material after completing a cycle, and all stop running; the control system controls each component to automatically start and stop as needed and control the feeding rhythm to meet the feeding needs of the vibration plate 6.

[0044] Adjustments before pushing are as follows: First adjust the equipment size before starting, adjust the left and right positions of the middle plate 1 44 and the positioning plate 2 45, so that the distance between the left side of the positioning plate 1 43 and the positioning plate 2 45 is equal to the width b of the paper cushion block 1; set the final target position of the paper cushion block 1 according to the width and position of the paper tape, and adjust the front and rear positions of the paper cushion block limit plate 60 accordingly. Adjust the sliding module 1 48 so that the distance between the front side of the slotted connecting plate 1 531 and the rear side of the paper cushion block limit plate 60 is exactly equal to the length a of the paper cushion block 1.

[0045] The material pushing process is as follows: the direct vibration conveying mechanism 8 conveys the paper cushion block 1 to the material pushing position by continuous vibration, which is the end of the direct vibration strip plate 32. At this time, the front end of the paper cushion block 1 is in contact with the paper cushion block limit plate 60. When the electric turntable rotates to the target position, the sliding module 2 57 starts, driving the material pushing finger 64 to push the paper cushion block 1 to the left, and pushes the paper cushion block 1 onto the electric turntable. Then the material pushing finger 64 returns to the original position to the right, waiting for the next paper cushion block 1 to be transported into place. The linear speed beat of the sliding module 2 57 matches the linear speed of the electric turntable, forming a reciprocating feeding with a certain beat.
