By automatically measuring the distance of the paper pad 35, if the difference on both sides exceeds the tolerance, it means that the paper pad 35 is tilted and shifted, and an alarm is issued to stop the machine to find the cause.

[0027] The empty paper tape releasing and pressing device of the embodiment of the present invention has the following working process: First, the seven empty paper tape material discs 2 of the required specifications and sizes are respectively passed through the empty paper tape disc clamping mechanism on the main shaft 7, and the spring column pin 10 is inserted into the corresponding positioning hole of the main shaft 7 to fix the empty paper tape material disc 2 on the main shaft 7; the two ends of the main shaft 7 are placed in the shaft seat 8, the empty paper tape material disc 2 at the working position is aligned with the empty paper tape tensioning mechanism 4, and then the two ends of the main shaft 7 are fixed with the positioning bolts 9, that is, the working position of the empty paper tape material disc 2 is fixed; when the empty paper tape 6 on the empty paper tape material disc 2 at the working position is used up and a new empty paper tape material disc 2 needs to be replaced, the new empty paper tape material disc 2 behind is manually moved to the working position for fixing, the head end of the new empty paper tape 6 is pulled out and glued to the tail end of the used empty paper tape 6, the bonding place is placed in the hot pressing mechanism 22, and the clamping bolt 23 on the upper part is tightened to compact and perform hot pressing bonding. The glue at the bonding place can be completely cured in about 40 seconds, and the clamping bolt 23 is loosened after the glue is cured. The empty paper tape material tray 2 is conveyed with an empty paper tape 6 by an empty paper tape tensioning mechanism 4 according to a certain tensioning force. The three-stage guide wheel conveys the empty paper tape 6 in a directional manner. The empty paper tape 6 passes through the first-stage guide wheel 18, the photoelectric switch 25, the hot pressing mechanism 22, the second-stage guide wheel 19, the electromagnetic damping wheel 21 and the third-stage guide wheel 20 in sequence, and is then conveyed between the pressure roller group and the electric turntable through the fourth-stage guide wheel 27 and the fifth-stage guide wheel 28. The photoelectric switch 25 determines whether there is an empty paper tape 6. When no empty paper tape 6 is detected, the control device stops. The outer periphery of the electric turntable is provided with a heat-resistant rubber plate for accommodating the paper pad 35, and the upper surface of the paper pad 35 is sprayed with glue. After the empty paper tape 6 is guided by the five-stage guide wheel 28, the inner side of the empty paper tape 6 is in contact with the side of the paper pad 35 on the outer periphery of the electric turntable coated with glue, and the outer side of the empty paper tape 6 is in contact with the driving belt 33 of the empty paper tape pressing mechanism 5. The empty paper tape pressing mechanism 5 cooperates with the electric turntable to firmly bond the paper pad 35 to the empty paper tape 6 to form the coil oil channel pad 3. The coil oil channel pad 3 continues to rotate with the electric turntable, and finally the coil oil channel pad 3 is wound into a roll by the winding mechanism. Further, a semicircular constant temperature heating belt can be provided at the lower part of the electric turntable, and the coil oil channel pad 3 is heated at a constant temperature by the constant temperature heating belt.

[0028] The speed of the driving wheel 31 and the driven wheel 32 of the pressure roller group is automatically matched with the speed of the electric turntable through the control system. The control system makes the linear speeds of the two the same, so that the paper pad 35 can be synchronously pressed onto the rotating empty paper belt 6. The pushing mechanism places the paper pad 35 into the heat-resistant rubber plate on the outer circle of the electric turntable at the rotation speed of the electric turntable, and adheres it to the empty paper belt 6 under a certain pressure. The pushing mechanism is based on the flying shear principle. Different spacings of the paper pad 35 correspond to different flying shear curves to match the different speeds of the electric turntable. The flying shear is an electronic cam motion that can be used to control the spacing lengths of many specifications.

[0029] like Figure 13-20As shown, the automatic feeding device for paper cushion blocks includes: a bucket elevator 38, a vibrating screen 39, a negative pressure dust removal mechanism 40 and a vibrating plate 41.

[0030] The bucket elevator 38 includes a storage bin at the bottom and a discharge bin at the top. The bottom of the discharge bin is open. A belt conveyor mechanism is arranged obliquely upward between the storage bin and the discharge bin. A plurality of horizontal transmission partitions are installed on the belt conveyor mechanism.

A transparent cover is installed above the belt conveyor mechanism and the transmission partitions to facilitate observation of the paper cushion block 35 at any time. The required batch of paper cushion block 35 materials are put into the storage bin of the bucket elevator 38 at one time. The bucket elevator 38 can realize continuous automatic feeding of the paper cushion block 35 through the belt conveyor mechanism and the transmission partitions. A photoelectric switch 1 is installed in the storage bin at the bottom of the bucket elevator 38 as a material-free sensor. The photoelectric switch 1 detects the paper cushion block 35 in the storage bin. When the photoelectric switch 1 detects that there is no material in the storage bin, the photoelectric switch 1 automatically sends a material-free alarm signal of the bucket elevator 38 to the control system. The parts of the bucket elevator 38 that are in contact with the paper cushion block 35 are preferably made of stainless steel.

[0032] Parameter table of vibrating screen 39 name Specification Remarks-Product Brand Vibrator K10 angle 5-10 degrees adjustable Vibration plate area 450mm*500mm power supply DC24V Solenoid valve 4V210 AirTac Machine material 304 Stainless Steel Dust hopper 304 Stainless Steel Full bin sensor Photoelectric Omron frame Non-standard, carbon steel spray The vibrating screen 39 includes a square bucket-shaped vibrating screen bin 44 with upper and lower openings and a rectangular vibrating screen plate 46. A photoelectric switch 2 48 is installed on the upper part of the vibrating screen bin 44 as a full bin sensor, and a photoelectric switch 3 is installed on the lower part of the vibrating screen bin 44 as an empty material sensor. A plurality of φ5mm sieve holes are evenly distributed on the plate surface of the vibrating screen plate 46. A waste hopper 53 is installed below the vibrating screen plate 46. Waste refers to dust and debris adhering to the paper pad 35. The bottom opening of the waste hopper 53 is connected to the upper end of the connecting pipe 42. A vibrating screen bin 44 is fixedly installed on the upper left side of the vibrating screen plate 46, and a downwardly inclined discharging chute 51 is installed on the right end of the vibrating screen plate 46. The discharging chute 51 is located above the vibrating plate 41. The side of the vibrating screen bin 44 close to the discharging chute 51 is a discharging side plate 49. A direct-feeding baffle 50 is installed at the edge of the vibrating screen plate 46 between the discharging side plate 49 and the discharging chute 51. A pair of direct-feeding baffles 50 are installed at the edge of the vibrating screen plate 46 in the length direction and are arranged in parallel. A rectangular discharging port is provided at the lower middle position of the discharging side plate 49. The rectangular discharging port is a rectangular through hole of a certain height. A discharging baffle that can move up and down is provided at the rectangular discharging port. The up and down movement of the discharging baffle is realized by the control system through controlling the discharging cylinder. The vibrating screen bin 44 and the direct-feeding baffle 50 are fixedly installed at the top of the bracket 47 by connecting parts and bolts, and an adjusting spring 45 is provided between the connecting parts and the top of the bracket 47. A pneumatic turbine vibrator 56 is installed at the middle position below the vibrating screen plate 46 . A solenoid valve 54 and a muffler 55 are installed on the pneumatic turbine vibrator 56 . The control system controls the pneumatic turbine vibrator 56 through the solenoid valve 54 .

[0033] The frame 12 is a rigid support frame. A laser ranging base is welded on the frame 12 near the vibration plate 41. Dual laser ranging mechanisms 52 are fixedly installed on the left and right ends of the laser ranging base by bolts. The laser beam of the dual laser ranging mechanism 52 shines on the inside of the vibration plate 41. The upper and lower limits of the height of the paper pad 35 in the vibration plate 41 are set in the control system. The bucket elevator 38 and the vibration screen 39 are automatically controlled to transport the paper pad 35 into the vibration plate 41 according to the measurement value of the dual laser ranging mechanism 52.

[0034] A vibration time controller is also added to the control system. After a period of time when the vibrating screen bin 44 is full of material, the discharge baffle is automatically lifted to a certain height, and the paper pad 35 is automatically fed to the vibrating screen plate 46 between a pair of direct feed baffles 50 through the rectangular discharge port at the bottom of the discharge side plate 49. The direct feed baffle 50 allows the paper pad 35 to be dispersed in a single layer on the vibrating screen plate 46, and the dust adhering to the paper pad 35 continues to fall into the waste hopper 53 through the vibration of the vibrating screen plate 46, and the paper pad 35 is deeply purified. Then, the paper pad 35 falls into the vibrating plate 41 through the discharge chute 51. Different vibration times and discharge baffle lifting heights are set for paper pads 35 of different sizes and dust contents, and the purification and dust removal effect of the paper pad 35 is ensured by setting the time interval and feeding speed.

[0035] The vibrating screen 39 is a non-standard customized structure. The vibrating screen 39 cooperates with the bucket elevator 38 to deliver the paper cushion block 35 to the vibrating plate 41. When the vibrating plate 41 gives a material request signal through the control system, the bucket elevator 38 lifts the paper cushion block 35 to start feeding. When the vibrating screen 39 is full, the bucket elevator 38 stops feeding to prevent the paper cushion block 35 from overflowing from the side of the vibrating screen 39. The vibration time of the vibrating screen plate 46 is set in the control system, and the vibrating screen 39 feeds the vibrating plate 41 regularly. The feeding process of the paper cushion block 35 continues until the vibrating plate 41 is full.

[0036] The vibrating screen 39 has the following characteristics: simple structure and low failure rate; the pneumatic turbine vibrator 56 is used in combination with the silencer 55, which can effectively reduce the noise to less than or equal to 75dB; the sieve holes on the vibrating screen plate 46 do not affect the catching of the paper pads 35 dropped from the bucket elevator 38, and can also collect the impurities in the paper pads 35 into the waste hopper 53 through vibration; the photoelectric switch 48 provided on the vibrating screen 39 detects that the vibrating screen bin 44 is full and sends a full bin signal to the control system, and the control system controls the bucket elevator 38 to stop running; the vibrating screen bin 44 After the warehouse is full, the vibrating screen plate 46 delays vibration for a certain period of time to screen out clean paper pads 35 materials; after the photoelectric switch 3 detects that there is no paper pads 35 materials at the bottom of the vibrating screen silo 44, it sends a signal that there is no material in the vibrating screen silo 44 to the control system, and the control system controls the bucket elevator 38 to automatically run and feed materials, and the cycle repeats; when the dual laser ranging mechanism 52 detects that the paper pads 35 in the vibrating disk 41 have reached the upper limit of the material height, the vibrating screen 39 stops running, and when the dual laser ranging mechanism 52 measures that the paper pads 35 in the vibrating disk 41 are out of material, the control system controls the vibrating screen 39 to run automatically.

[0037] Parameter table of negative pressure dust removal mechanism 40 name Specification Volume 30L power 2200W suction 24kPa power supply AC380V / 50Hz frame Non-standard, carbon steel spray Dust removal structure Dust barrier + Hypa The negative pressure dust removal mechanism 40 has the following characteristics: the negative pressure dust removal mechanism 40 is centrally controlled by the control system and can be linked with the vibrating screen 39. The negative pressure dust removal mechanism 40 only works during the vibration feeding period of the vibrating screen 39, which saves energy and reduces consumption; the dust separator and HEPA inside the negative pressure dust removal mechanism 40 are easy to disassemble and maintain, and can be washed with water; strong suction and explosion-proof; automatic pressure relief; waterproof and leakage-proof; easy to maintain; easy to clean.

[0038] The vibration plate 41 includes: a vibration plate vibration mechanism 57, a vibration plate bottom plate 58, a vibration plate cylinder wall 76, a material channel and a pick. The vibration plate bottom plate 58 is a circular structure with an upwardly extending convex plate on the edge. The diameter of the vibration plate bottom plate 58 is larger than the diameter of the vibration plate cylinder wall 76. A corner of the bottom of the vibration plate cylinder wall 76 is welded to the vibration plate bottom plate 58. The vibration plate cylinder wall 76 and the vibration plate bottom plate 58 together constitute a vibration plate material bin. A vibration plate cylinder wall notch 77 is provided between the bottom of the vibration plate cylinder wall 76 and the vibration plate bottom plate 58. The vibration plate 41 is used to screen the paper pads 35 and arrange the paper pads 35 in rows. The vibration speed of the vibration plate vibration mechanism 57 can be adjusted. The vibration plate bottom plate 58 is fixedly installed above the vibration plate vibration mechanism 57. An inclined spring sheet is arranged between the vibration plate bottom plate 58 and the vibration plate vibration mechanism 57. The vibration plate bottom plate 58 and the vibration plate cylinder wall 76 are used to receive the paper pad 35 material poured down from the vibration screen 39. The material height of the paper pad 35 in the vibration plate silo is detected in real time by the dual laser ranging mechanism 52, and the total material height of the paper pad 35 is automatically controlled to be kept within a certain range. The inner wall of the vibration plate cylinder wall 76 is provided with a spiral upward vibration plate silo inner material channel 59. The pulse electromagnet in the vibration plate vibration mechanism 57 generates power on and off under the action of current, so that the vibration plate bottom plate 58 vibrates vertically up and down. Due to the inclination of the spring sheet connected to the vibration plate bottom plate 58, the vibration plate bottom plate 58 will make a torsional pendulum vibration in one direction. Due to this vibration, the paper pad 35 in the vibration plate silo will continuously move forward and gradually rise along the inner material channel 59 of the vibration plate silo. In this process, the paper pad 35 will continuously adjust its posture and spread evenly. The width of the inner channel 59 of the vibrating disk silo is limited to accommodate only one paper pad 35, so the paper pads 35 can only be discharged in a row on the inner channel 59 of the vibrating disk silo.

[0039] The outer wall of the vibrating disk barrel wall 76 is provided with a spiral downward vibrating disk material bin outer channel 1 60 and a vibrating disk material bin outer channel 2 61, and the discharge port of the vibrating disk material bin inner channel 59 is respectively connected with the feed port of the vibrating disk material bin outer channel 1 60 and the vibrating disk material bin outer channel 2 61, and a material change channel baffle 62 is provided at the connection position, and the discharge ports of the vibrating disk material bin outer channel 1 60 and the vibrating disk material bin outer channel 2 61 are connected with the vibrating disk outlet channel 66. A double material channel is provided on the outer wall of the vibrating disk barrel wall 76, and the vibrating disk material bin outer channel 2 61 is suitable for paper pads 35 with the same length and width. The installation position of the material change channel baffle 62 is adjusted by bolts as needed, so that one of the vibrating disk material bin outer channel 1 60 and the vibrating disk material bin outer channel 2 61 is closed and the other is opened. A paddle 1 63 is provided at the outlet of the inner channel 59 of the vibrating disk silo. By setting the height of the paddle 1 63, the paddle 1 63 can break up the paper cushion blocks 35 vibrated out of the bottom plate 58 of the vibrating disk. A paddle 2 64 is respectively installed at the feed inlet of the outer channel 1 60 of the vibrating disk silo and the outer channel 2 61 of the vibrating disk silo. By setting the height of the paddle 2 64, it is ensured that the paper cushion blocks 35 are transported outward in a single layer. A paddle 3 65 is respectively installed at the discharge outlet of the outer channel 1 60 of the vibrating disk silo and the outer channel 2 61 of the vibrating disk silo. By setting the height of the paddle 3 65, the paper cushion blocks 35 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 35 is 100% correct. Because the arc structure of the paper cushion block 35 has a small processing arc, especially when the length and width of the paper cushion block 35 are the same, there may still be errors in adjusting the direction of the paper cushion block 35 only by relying on the specially designed paddle 1 63 and paddle 2 64, so a paddle 3 65 is added near the vibrating plate outlet channel 66. The paddle 3 65 blocks the paper cushion block 35 with the wrong height size, and uses the arc to guide the paper cushion block 35 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 35 with the correct height can pass.

[0040] The discharge end of the vibrating plate outlet channel 66 is connected to the front end (feeding end) of the direct vibration conveying mechanism 43. The direct vibration conveying mechanism 43 includes a straight vibration strip plate 67. The middle part of the straight vibration strip plate 67 is fixedly installed on the straight vibration vibration mechanism 70. The cross section of the straight vibration strip plate 67 is L-shaped. A fixed baffle plate 68 is fixedly installed on the thicker side of the straight vibration strip plate 67, and a push plate 69 is movably installed on the thinner side of the straight vibration strip plate 67. The push plate 69 and the fixed baffle plate 68 cooperate with the upper surface of the straight vibration strip plate 67 to form a slideway for the paper supply pad 35 to move. The distance between the push plate 69 and the fixed baffle plate 68 can be adjusted to adapt to paper pads 35 of different widths. A material shortage detection mechanism 74 is fixedly installed at the outer front end of the fixed baffle plate 68, and a full material detection mechanism 75 is fixedly installed at the outer rear end of the fixed baffle plate 68. An L-shaped height paddle 72 is provided above the feeding end of the straight-vibrating long strip 67. The spacing between the horizontal plate of the height paddle 72 and the straight-vibrating long strip 67 can be adjusted to accommodate paper pads 35 of different thicknesses. At the same time, the height paddle 72 can push the upper paper pad 35 into the slideway on the straight-vibrating long strip 67 without forming material accumulation. A pushing cylinder 71 and a laser rangefinder 73 are respectively provided on both sides of the straight-vibrating long strip 67 near the height paddle 72. A notch is provided on the straight-vibrating long strip 67 at the push rod of the pushing cylinder 71. The laser rangefinder 73 can identify the arc direction of the paper pad 35 and whether there is material accumulation. The measured distance value of the laser rangefinder 73 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 the paper pad 35 is in the wrong direction. The push rod of the pushing cylinder 71 pushes the paper pad 35 out. An inclined material guide slide is provided below this position, and the pushed-out paper pad 35 falls back into the vibration disk bottom plate 58. The full material detection mechanism 75 is linked with the laser rangefinder 73. When the full material detection mechanism 75 detects that there is material and the laser rangefinder 73 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 41 to stop running. When the lack of material detection mechanism 74 and the laser rangefinder 73 do not detect the paper pad 35 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 41 to automatically start feeding.

[0041] The vibration disk 41 and the direct vibration conveying mechanism 43 are used in conjunction with each other. The vibration disk 41 is used to sort the paper pads 35, and the direct vibration conveying mechanism 43 is used to act as a buffer and detect the paper pads 35. The direct vibration conveying mechanism 43 can also provide a stable and accurate feeding position. Under the action of the vibration disk 41, the paper pads 35 slide out along the spiral chute in sequence, and are arranged in length and width according to the requirements of the drawings. They are sent to the bottom of the glue spraying mechanism through the direct vibration conveying mechanism 43, and the glue spraying mechanism sprays glue on the paper pads 1 arranged in the moving slide between the push plate 69 and the fixed baffle 68. The frame of the vibration disk 41 and the frame of the glue spraying mechanism are independent of each other to avoid the vibration of the vibration disk 41 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.

[0042] The automatic feeding device for paper cushion blocks of the embodiment of the present invention has the following working process: The paper pad 35 is sent to the vibrating screen 39 by the bucket elevator 38, and the fine impurities therein are screened out by the vibrating screen 39. Under the combined action of gravity and negative pressure suction, the paper pad 35 is collected together by the negative pressure dust removal mechanism 40 through the sieve holes, and the clean paper pad 35 after impurities are removed falls into the vibrating plate 41. The paper pad 35 material is put into the large hopper at the bottom of the bucket elevator 38 at one time. The PLC control system controls the start and stop of multiple devices in linkage, and detects the material level in the vibrating plate 41 in real time. When the material level reaches the low level, the bucket elevator 38 automatically starts and sends the raw materials into the vibrating screen 39; the material situation in the vibrating screen 39 is automatically monitored in real time. When the vibrating screen 39 is full, the bucket elevator 38 stops, and the vibrating screen 39 continues to vibrate for a certain period of time (the time can be set arbitrarily according to the cleanliness of the raw materials) to ensure that the material debris and dust have passed through After being cleaned by the negative pressure dust removal mechanism 40, the paper pad 35 is automatically placed in the vibration plate 41; when the vibration screen 39 automatically detects that there is no material, the bucket elevator 38 is started to feed the material, and the paper pad 35 is repeatedly purified and placed in the vibration plate 41; when the vibration plate 41 is full of material, the bucket elevator 38, the vibration screen 39 and the negative pressure dust removal mechanism 40 stop running after completing a cycle; the control system controls each component to automatically start and stop and control the feeding rhythm as needed to meet the feeding needs of the vibration plate 41.

[0043] like Fig.21As shown, the automatic glue spraying device for paper pads includes: a glue spraying barrel 89, a glue spraying valve 82 and a glue spraying nozzle anti-blocking device. The glue spraying barrel 89 is connected to a large-capacity glue storage barrel through a sealing hose, and the glue liquid is placed in the glue storage barrel in a sealed manner. The glue spraying barrel 89 is connected through the large-capacity glue storage barrel to avoid frequent replenishment of glue liquid into the glue spraying barrel 89 during the glue spraying process; the glue storage barrel is placed on a fixed workbench next to the automatic glue spraying device, and the glue storage barrel is a sealed structure design made of stainless steel to reduce the contact between the glue liquid and the air and avoid the glue liquid solidifying over a long period of time. The glue storage barrel is connected to the inflation pipeline through a sealed pipeline, and the inflation pipeline continuously fills the glue storage barrel with dry air of a positive pressure value. A precision pressure regulating valve is installed on the inflation pipeline to adjust the air pressure. The precision pressure regulating valve is provided with a pressure regulating knob to adjust the glue supply pressure to ensure the stability of the glue supply pressure.

[0044] The glue supply pressure of the glue storage barrel is adjustable, and it is equipped with a material shortage alarm mechanism; the glue liquid can be stored and used in the glue storage barrel for a long time, and the fully enclosed pressure-adjustable glue storage barrel continuously provides glue liquid for the glue spray barrel 89 at the glue spray valve 82. The glue spray barrel 89 needs to move at high speed with the glue spraying device, so the glue spray barrel 89 is designed to have a small capacity and is very light. The glue liquid is automatically transported from the glue storage barrel to the glue spray barrel 89 through a sealed hose + air pressure. An electronic scale is installed at the bottom of the glue storage barrel, and the glue storage barrel is placed on the electronic scale. The electronic scale is electrically connected to the control system, and the upper and lower alarm limits of the glue liquid weight in the glue storage barrel are set in the control system, which is convenient for prompting the glue storage barrel to replenish the glue liquid and avoid the glue liquid in the glue storage barrel being too full or missing. At the same time, the control system is electrically connected to a three-color sound and light alarm lamp, which is installed on the upper part of the automatic glue spraying device bracket, and automatically alarms the glue liquid in the glue storage barrel to be too full or missing, reminding that manual intervention is required.

The bottom end of the slider 79 is slidably connected to the linear guide 91. The center of the slider 79 is provided with an internal threaded hole. The ball screw 92 passes through the slider 79. The internal threaded hole of the slider 79 cooperates with the external thread of the ball screw 92. The right side of the slider 79 is fixedly installed with the connecting transition plate 90. The pneumatic slide 81 is fixedly installed on the right side of the connecting transition plate 90. The glue spraying valve 82 is fixedly installed on the sliding plate on the right side of the pneumatic slide 81. The three-dimensional movement of the glue spraying valve 82 is realized by the cooperation of the ball screw 92 and the pneumatic slide 81. A pair of semicircular arc-shaped elastic mounting clips are fixedly installed on the upper right side of the glue spraying valve 82. The upper part of the glue spraying barrel 89 is clamped in the mounting clip. The glue outlet of the glue spraying barrel 89 is located at the lower end, and the outer periphery of the glue outlet of the glue spraying barrel 89 is processed with pipe threads. The glue outlet of the glue spray barrel 89 is fastened to the component module of the glue spray valve 82 through a pipe thread using a nut, and the glue enters the glue spray valve 82 from the glue outlet of the glue spray barrel 89 through the internal channel of the component module.

[0046] The glue spraying valve 82 is a piezoelectric glue dispensing valve, for example, a piezoelectric injection valve of model S1000. The glue spraying valve 82 can accurately spray glue (dispense glue) on multiple paper pads 35 at one time through three-dimensional rapid movement.

[0047] A cylinder lifting mechanism 83 is also fixedly mounted on the device bracket, and the cylinder lifting mechanism 83 is located at the right rear of the glue spraying valve 82. The glue spraying nozzle blocking prevention device is installed on the cylinder lifting mechanism 83, and the glue spraying nozzle blocking prevention device can prevent the conical glue spraying nozzle of the glue spraying valve 82 from being blocked during daily shutdown. The glue spraying nozzle blocking prevention device includes a waste glue box 86 and a sealing glue box 87, and the waste glue box 86 and the sealing glue box 87 are arranged side by side on the upper horizontal fixed plate 88, and the sealing glue box 87 is filled with glue liquid. The upper horizontal fixed plate 88 is fixedly connected to the middle vertical fixed plate 85 and the lower horizontal fixed plate 7 as a whole. The vertical fixed plate 85 is fixedly connected to the lifting cylinder of the cylinder lifting mechanism 83. The direct vibration conveying mechanism 43 for conveying paper pads 35 is installed in the space formed by the lower horizontal fixed plate 84, the vertical fixed plate 85 and the upper horizontal fixed plate 88.

[0050] The automatic glue spraying device for paper pads of the embodiment of the present invention has the following working process: After process tests, glue spraying tracks and glue quantity control modules are set in the control system for different paper pads 35. After glue spraying, after the paper pads 35 are pressed and bonded to the paper tape, it is ensured that the glue sprayed on the paper pads 35 will not overflow to the outside of the paper pads 35 to form glue tumors. The glue tumors will produce local discharge at high voltage and affect the normal operation of the transformer. Through the control of the glue spraying track and glue quantity control module, the control system automatically links and reads the corresponding operation data according to the size specifications of the paper pads 35, accurately controls the glue coating position and glue coating amount, ensures that the glue does not leak or overflow, and accurately controls the minimum glue amount required to ensure that the paper pads 35 and the empty paper tape 6 are firmly bonded.

[0051] After the glue spraying work is finished, the glue spraying valve 82 is automatically driven to move to the top of the glue sealing box 87 of the glue spraying nozzle anti-blocking device through the ball screw 92 and the pneumatic slide 81, and the glue sealing box 87 is driven to move up through the action of the cylinder lifting mechanism 83, so that the conical glue spraying nozzle of the glue spraying valve 82 is immersed in the glue sealing box 87, and the glue sealing box 87 seals the entire conical glue spraying nozzle liquid to avoid glue blockage caused by the conical glue spraying nozzle contacting the air when it is not used for a short period of time. When it is necessary to spray glue again, the glue spraying nozzle anti-blocking device is moved down through the action of the cylinder lifting mechanism 83, and the glue spraying valve 82 is automatically driven to move to the top of the waste glue box 86 of the glue spraying nozzle anti-blocking device through the ball screw 92 and the pneumatic slide 81. The control system controls the action of the glue spraying valve 82 to automatically spray glue a few times, and the sprayed glue is collected through the waste glue box 86. After cleaning and observing that the conical glue spraying nozzle sprays glue normally, the paper pad automatic glue spraying device is started and operated normally.
