[0030] like Figure 1 As shown, the paper pad 1 used on the coil oil channel pad strip is a hexagonal cuboid structure with a length of a, a width of b, and a height of c. The width of the paper strip 2 is d. When bonding, the length direction of the paper pad 1 must be consistent with the width direction of the paper strip 2. The four long edges of the paper pad 1 along its length direction are machined with arc structures, while the other eight edges are right-angle structures. After machining the arc structures on the four long edges, when the paper strip 2 is wrapped around the front / back and top / bottom four sides of the paper pad 1, the arc structures are less likely to cut the paper strip 2 during the stress process. When bonding the paper pad 1 to the paper strip 2, the accuracy of the orientation of the paper pad 1 bonded to the paper strip 2 and the accuracy of the spacing e between adjacent paper pad 1s must both reach 100%.

A pair of light barriers is installed in the lower storage bin of the bucket elevator 3 as a no-material sensor, which detects the paper dunnage 1 in the storage bin. When the pair of light barriers detects that there is no material in the storage bin, the pair of light barriers automatically sends a no-material alarm signal of the bucket elevator 3 to the control system. The components in contact with the paper dunnage 1 in the bucket elevator 3 are preferably made of stainless steel.

[0038] The vibrating screen 4 includes a square-shaped, open-top and bottom-bottom vibrating screen hopper 9 and a rectangular vibrating screen plate 11. A through-beam photoelectric switch 13 is installed on the upper part of the vibrating screen hopper 9 as a full-hopper sensor, and a through-beam photoelectric switch 3 is installed on the lower part of the vibrating screen hopper 9 as a no-material sensor. Several φ5mm screen holes are evenly distributed on the surface of the vibrating screen plate 11. A waste hopper 18 is installed below the vibrating screen plate 11. Waste refers to dust and debris adhering to the paper pad block 1. The bottom opening of the waste hopper 18 connects to the upper end of the connecting pipe 7. A vibrating screen hopper 9 is fixedly installed on the upper left side of the vibrating screen plate 11. A downwardly inclined discharge chute 16 is installed on the right end of the vibrating screen plate 11, located above the vibrating plate 6. A discharge side plate 14 is located on the side of the vibrating screen hopper 9 closest to the discharge chute 16. A direct feed baffle 15 is installed along the edge of the vibrating screen plate 11 between the discharge side plate 14 and the discharge chute 16. A pair of direct feed baffles 15 are installed parallel to each other along the length of the vibrating screen plate 11. A rectangular discharge port is opened at the lower middle position of the discharge side plate 14. The rectangular discharge port is a rectangular through hole of a certain height. A discharge baffle that can move up and down is installed at the rectangular discharge port. The up and down movement of the discharge baffle is achieved by the control system through the control of the discharge cylinder. The vibrating screen hopper 9 and the direct feed baffle 15 are fixedly installed on the top of the bracket 12 by connectors and bolts. An adjusting spring 10 is installed between the connectors and the top of the bracket 12. A pneumatic turbine vibrator 21 is installed at the lower center of the vibrating screen plate 11. A solenoid valve 19 and a silencer 20 are installed on the pneumatic turbine vibrator 21. The control system controls the pneumatic turbine vibrator 21 through the solenoid valve 19.

[0039] The frame 12 is a rigid support frame. A laser ranging base is welded to the frame 12 near the vibrating plate 6. A dual laser ranging mechanism 17 is fixed to the left and right ends of the laser ranging base by bolts. The laser beam of the dual laser ranging mechanism 17 shines into the interior of the vibrating plate 6. The control system sets the upper and lower limits of the height of the paper pad 1 in the vibrating plate 6. Based on the measurement value of the dual laser ranging mechanism 17, the bucket elevator 3 and the vibrating screen 4 are automatically controlled to feed the paper pad 1 into the vibrating plate 6.

[0040] A vibration time controller was also added to the control system. After the vibrating screen hopper 9 is full, the discharge baffle is automatically raised to a certain height after a period of time. The paper pad 1 is automatically fed through the rectangular discharge port at the bottom of the discharge side plate 14 onto the vibrating screen plate 11 between a pair of direct feed baffles 15. The direct feed baffles 15 disperse the paper pad 1 in a single layer on the vibrating screen plate 11, and the vibration of the vibrating screen plate 11 causes the dust adhering to the paper pad 1 to fall into the waste hopper 18, thus deeply purifying the paper pad 1. Then, the paper pad 1 falls into the vibrating plate 6 through the discharge chute 16. Different vibration times and discharge baffle lifting heights are set for paper pad 1 of different sizes and dust contents. The purification and dust removal effect of the paper pad 1 is ensured by setting the time interval and feeding speed.

[0041] The vibrating screen 4 is a non-standard structure, and the vibrating screen 4 cooperates with the bucket elevator 3 to send the paper dunnage 1 to the vibrating tray 6. When the vibrating tray 6 gives a signal of required material through the control system, the bucket elevator 3 lifts the paper dunnage 1 to start feeding. When the vibrating screen 4 is full, the bucket elevator 3 stops feeding to prevent the paper dunnage 1 from overflowing from the side of the vibrating screen 4. The vibration time of the vibrating screen plate 11 is set in the control system, the vibrating screen 4 feeds the vibrating tray 6 in a time manner, and the feeding process of the paper dunnage 1 continues until the vibrating tray 6 is full.

[0042] The vibrating screen 4 has the following characteristics: simple structure and low failure rate; the pneumatic turbine vibrator 21 is matched with the silencer 20, which can effectively reduce the noise and make the noise less than or equal to 75 dB; the screen holes on the vibrating screen plate 11 do not affect the paper dunnage 1 falling from the bucket elevator 3, and can also collect the impurities in the paper dunnage 1 into the waste hopper 18 through vibration; the pair of photoelectric switches 13 are arranged on the vibrating screen 4, and send a full bin signal to the control system after detecting that the vibrating screen bin 9 is full, and the control system controls the bucket elevator 3 to stop running; after the vibrating screen bin 9 is full, the vibrating screen plate 11 vibrates for a certain time, and the clean paper dunnage 1 material is screened out; the pair of photoelectric switches 13 send a vibrating screen bin 9 empty signal to the control system after detecting that there is no paper dunnage 1 material at the bottom of the vibrating screen bin 9, and the control system controls the bucket elevator 3 to automatically run and feed in a cycle; when the double laser ranging mechanism 17 detects that the paper dunnage 1 in the vibrating tray 6 reaches the upper limit of the material height, the vibrating screen 4 stops running, and when the double laser ranging mechanism 17 detects that the paper dunnage 1 in the vibrating tray 6 is insufficient, the control system controls the vibrating screen 4 to automatically run.

[0043] Parameter table of negative pressure dust removal mechanism 5

[0044] Name Specification Volume 30L Power 2200W Suction 24kPa Power supply AC380V / 50Hz Rack Non-standard, carbon steel plastic spraying Dust removal structure Dust isolation + Hepa

[0045] The negative pressure dust removal mechanism 5 has the following characteristics: the negative pressure dust removal mechanism 5 can be centrally controlled by the control system, and can be linked with the vibrating screen 4. The negative pressure dust removal mechanism 5 only works during the vibration feeding of the vibrating screen 4, which saves energy and reduces consumption; the dust separation inside the negative pressure dust removal mechanism 5 and the Hapa are easy to disassemble and maintain, and can be washed with water; large suction, explosion-proof; automatic pressure relief; waterproof and leakage-proof; easy to maintain; easy to clean.

[0046] The vibrating disc 6 comprises a vibrating disc vibrating mechanism 22, a vibrating disc bottom plate 23, a vibrating disc cylinder wall 41, a channel and a pusher. The vibrating disc bottom plate 23 is a disc-shaped structure with a flange with an upwardly extending flange plate. The diameter of the vibrating disc bottom plate 23 is larger than the diameter of the vibrating disc cylinder wall 41. The vibrating disc cylinder wall 41 is welded at the bottom of a corner on the vibrating disc bottom plate 23. The vibrating disc cylinder wall 41 and the vibrating disc bottom plate 23 together constitute a vibrating disc hopper. The vibrating disc cylinder wall 41 and the vibrating disc bottom plate 23 are provided with a vibrating disc cylinder wall gap 42 at the bottom. The vibrating disc 6 is used for screening and arranging the paper dunnage blocks 1 in rows. The vibrating speed of the vibrating disc vibrating mechanism 22 can be adjusted. The vibrating disc bottom plate 23 is fixedly installed above the vibrating disc vibrating mechanism 22. An inclined spring plate is arranged between the vibrating disc bottom plate 23 and the vibrating disc vibrating mechanism 22. The vibrating disc bottom plate 23 and the vibrating disc cylinder wall 41 are used for receiving the paper dunnage blocks 1 falling from the vibrating screen 4. The double laser ranging mechanism 17 is used for real-time detection of the material height of the paper dunnage blocks 1 in the vibrating disc hopper. The total material height of the paper dunnage blocks 1 is automatically controlled to be kept within a certain range. The inner wall of the vibrating disc cylinder wall 41 is provided with a vibrating disc hopper inner side channel 24 spirally upward. The pulse electromagnet in the vibrating disc vibrating mechanism 22 is switched on and off under the action of current, so that the vibrating disc bottom plate 23 vertically vibrates up and down. Due to the inclination of the spring plate connected to the vibrating disc bottom plate 23, the vibrating disc bottom plate 23 will make a torsional vibration in one direction. The paper dunnage blocks 1 in the vibrating disc hopper will continuously move forward and gradually rise along the vibrating disc hopper inner side channel 24 due to the vibration. In this process, the paper dunnage blocks 1 will continuously adjust the posture and evenly spread out. The width of the vibrating disc hopper inner side channel 24 is limited to only accommodate one paper dunnage block 1, so the paper dunnage blocks 1 can only be discharged in rows on the vibrating disc hopper inner side channel 24.

[0047] The outer wall of the vibrating disc cylinder wall 41 is provided with spiral downward vibrating disc bin outside material channel one 25 and vibrating disc bin outside material channel two 26, the vibrating disc bin inside material channel 24 discharge port is respectively communicated with the vibrating disc bin outside material channel one 25 and the vibrating disc bin outside material channel two 26 inlet, and the communication position is provided with the material channel baffle 27, the vibrating disc bin outside material channel one 25 and the vibrating disc bin outside material channel two 26 discharge port are communicated with the vibrating disc outlet material channel 31.The outer wall of the vibrating disc cylinder wall 41 is provided with double material channel, the vibrating disc bin outside material channel two 26 is suitable for the paper pad block 1 with the same length and width, and the installation position of the material channel baffle 27 is adjusted by bolt according to the need, so that one of the vibrating disc bin outside material channel one 25 and the vibrating disc bin outside material channel two 26 is closed, and the other is opened.A baffle one 28 is arranged at the outlet of the vibrating disc bin inside material channel 24, the height of the baffle one 28 is set, so that the baffle one 28 can scatter the paper pad block 1 vibrated from the vibrating disc bottom plate 23.A baffle two 29 is respectively installed at the inlet of the vibrating disc bin outside material channel one 25 and the vibrating disc bin outside material channel two 26, the height of the baffle two 29 is set, so that the paper pad block 1 is single-layer outwardly conveyed.A baffle three 30 is respectively installed at the discharge port of the vibrating disc bin outside material channel one 25 and the vibrating disc bin outside material channel two 26, the height of the baffle three 30 is set, the paper pad block 1 with wrong direction is pushed out and dropped back into the vibrating disc bin, so that the direction of the paper pad block 1 is 100% correct.Because the paper pad block 1 has small arc structure processing radian, especially when the length and width of the paper pad block 1 are the same, only the baffle one 28 and the baffle two 29 with special design can adjust the direction of the paper pad block 1, so the baffle three 30 is added near the vibrating disc outlet material channel 31.The baffle three 30 blocks the paper pad block 1 with incorrect height, and guides the paper pad block 1 to drop back to the bottom of the vibrating disc bin by radian, so as to be vibrated again to participate in screening again, only the paper pad block 1 with correct height can pass.

[0048] The discharge end of the vibration disc outlet channel 31 is communicated with the front end (feeding end) of the straight vibration conveying mechanism 8, which comprises a straight vibration long strip plate 32 with a shallow groove in the middle of the length direction, is fixedly installed on the straight vibration mechanism 35 in the middle, has an L-shaped cross section, and has a fixed baffle 33 fixedly installed on the thicker side, and has a push plate 34 movably installed on the thinner side. The cooperation between the push plate 34 and the fixed baffle 33 forms a slide for the movement of the paper cushion block 1 on the upper surface of the straight vibration long strip plate 32. The spacing between the push plate 34 and the fixed baffle 33 can be adjusted to adapt to paper cushion blocks 1 of different widths. A full material detection mechanism 40 is fixedly installed on the outer side of the rear end of the fixed baffle 33, and a lack of material detection mechanism 39 is fixedly installed on the outer side of the front end of the fixed baffle 33. An L-shaped height dial piece 37 is arranged above the front end of the straight vibration long strip plate 32. The spacing between the horizontal plate of the height dial piece 37 and the straight vibration long strip plate 32 can be adjusted to adapt to paper cushion blocks 1 of different thicknesses. At the same time, the arrangement of the height dial piece 37 can push the upper layer of the individual double-layer paper cushion block 1 down, without forming accumulated material. A pushing material cylinder 36 and a laser range finder 38 are arranged on the two sides of the straight vibration long strip plate 32 close to the height dial piece 37. The straight vibration long strip plate 32 corresponding to the push rod of the pushing material cylinder 36 is provided with a notch. The laser range finder 38 can identify the circular arc direction of the paper cushion block 1 and whether there is accumulated material. The measurement distance value of the laser range finder 38 should be approximately equal to the circular arc radius. If the measurement distance value is close to zero, it means that there is no circular arc, which means that the paper cushion block 1 is in the wrong direction. The push rod of the pushing material cylinder 36 pushes the paper cushion block 1 out. An inclined guide slide is arranged below this position, and the pushed-out paper cushion block 1 falls back into the vibration disc bottom plate 23. The full material detection mechanism 40 is linked with the laser range finder 38. The full material detection mechanism 40 detects material and the laser range finder 38 does not detect data mutation (block gap) within a certain time, which is full material. The control system controls the vibration disc 6 to stop running. The lack of material detection mechanism 39 and the laser range finder 38 do not detect the paper cushion block 1 within a certain time, which is lack of material. The control system controls the vibration disc 6 to automatically start feeding when there is lack of material.

[0049] The vibrating disc 6 is used for arranging the paper cushion block 1, and the straight vibration conveying mechanism 8 is used for buffering and detecting the paper cushion block 1, and the straight vibration conveying mechanism 8 can provide a stable and accurate feeding position. The paper cushion block 1 is sequentially slid out along the spiral chute under the action of the vibrating disc 6, and is arranged in the length and width directions according to the requirements of the drawing, and the paper cushion block 1 is sent to the lower side of the glue spraying mechanism through the straight vibration conveying mechanism 8, and the glue spraying mechanism sprays glue on the paper cushion block 1 arranged in the moving slide between the push plate 34 and the fixed baffle 33. The frame of the vibrating disc 6 and the frame of the glue spraying mechanism are independent of each other, so that the vibration of the vibrating disc 6 does not have a negative impact on automatic glue spraying. The paper cushion block 1 has a margin around the periphery, because the glue liquid will spread to the periphery during compression, and the vibration of the straight vibration conveying mechanism 8 does not have a great impact on glue spraying.

[0050] The working process of the paper cushion block automatic feeding device is as follows:

[0051] The paper cushion block 1 is sent to the vibrating screen 4 through the bucket elevator 3, and the fine impurities in the paper cushion block 1 are screened out by the vibrating screen 4. The clean paper cushion block 1 after removing the impurities falls into the vibrating disc 6 under the joint action of the gravity and the negative pressure suction force through the screen hole and the negative pressure dust removal mechanism 5. The paper cushion block 1 is automatically put into the vibrating disc 6 after being purified by the bucket elevator 3, the PLC control system controls the start and stop of multiple devices, and the material level in the vibrating disc 6 is detected in real time. When the material level reaches the low position, the bucket elevator 3 is automatically started to send the raw material into the vibrating screen 4. The material in the vibrating screen 4 is automatically monitored in real time, and the bucket elevator 3 is stopped when the vibrating screen 4 is full. The vibrating screen 4 continues to vibrate for a certain period of time (the time can be arbitrarily set according to the cleanliness of the raw material), so that the material debris and dust are cleaned by the negative pressure dust removal mechanism 5, and the paper cushion block 1 is automatically put into the vibrating disc 6. When the vibrating screen 4 is empty, the bucket elevator 3 is started to feed, and the paper cushion block 1 is repeatedly put into the vibrating disc 6 after being purified. When the vibrating disc 6 is full, the bucket elevator 3, the vibrating screen 4 and the negative pressure dust removal mechanism 5 complete a cycle without feeding material, and all stop running. The control system controls the automatic start and stop of each component and the feeding rhythm according to the needs, so as to meet the feeding demand of the vibrating disc 6.
