The electric turntable is rotatably mounted between the width direction of the frame 1, and the lower part of the electric turntable is located in the cabinet. Considering the simplicity of the composition, Figure 2 Only the empty paper tape releasing and pressing device is shown, while the automatic glue spraying device for the paper pad block, the automatic feeding device for the paper pad block and the electric turntable are not shown.

The empty paper tape pressing mechanism 5 is used to press the empty paper tape 6 against a paper pad 35 sprayed with glue. The paper pad 35 is firmly bonded to the empty paper tape 6 at a certain distance to form a coil oil channel pad 3. The coil oil channel pad 3 is wound into a roll by a finished product winding mechanism to form a finished product.

[0022] The empty paper tape release mechanism includes a main shaft 7 and an empty paper tape material tray 2. The main shaft 7 is a circular steel pipe with the upper part processed into a platform. Positioning bolt holes are respectively processed at both ends of the upper surface platform of the main shaft 7. A number of positioning holes are evenly distributed in the middle of the upper surface platform of the main shaft 7. The positioning holes are used to position and install the empty paper tape material tray 2. The two ends of the main shaft 7 are fixedly installed in the shaft seat 8. A pair of shaft seats 8 are symmetrically fixed on the middle crossbeam in the length direction of the frame 1 by bolts. The shaft seat 8 is a rectangular structure as a whole, including an upper seat and a lower seat of a snap-fit ​​structure. The upper surface of the middle part of the lower seat is processed with arc steps matching the lower parts of the two ends of the main shaft 7. The middle part of the main shaft 7 is equipped with several sleeves corresponding to the positioning holes, and the empty paper tape material disc 2 is rotatably mounted on the sleeves. First, the two ends of the main shaft 7 are installed in the arc steps. The working position of the empty paper tape material disc 2 corresponds to the empty paper tape tensioning mechanism 4. After the working position of the empty paper tape material disc 2 is adjusted, the upper seat is clamped and mounted on the lower seat. The upper horizontal panel of the upper seat is processed with bolt through holes. The positioning bolts 9 pass through the bolt through holes and are screwed into the positioning bolt holes at both ends of the main shaft 7 to firmly install the main shaft 7 in the shaft seat 8.

[0023] The sleeve includes a sleeve body 34, the left end of the sleeve body 34 is integrally formed with a glass wool plate disc 11, the diameter of the glass wool plate disc 11 is larger than the diameter of the sleeve body 34, the right end of the sleeve body 34 is provided with a groove step, the groove step is processed with threads, and the round nut 12 is threadedly sleeved on the right end of the sleeve body 34. The width of the empty paper tape material disc 2 usually varies in the range of 6-20mm. In order to ensure that the round nut 12 can be tightly attached to the right side of the empty paper tape material disc 2 and reduce the time for tightening the round nut 12, according to the different widths of the empty paper tape material disc 2, several layers of adjusting washers 13 are provided on the left side of the round nut 12 ( Figure 4There are three layers of adjusting washers 13, which can be one to three layers of adjusting washers 13, or no adjusting washers 13 are provided. A spring pin 10 is inserted into the positioning hole on the main shaft 7 on the left side of the glass wool plate disc 11. The sleeve body 34, the glass wool plate disc 11, the adjusting washer 13, the spring pin 10 and the round nut 12 together constitute the empty paper tape material disc clamping mechanism. The left side of the empty paper tape material disc clamping mechanism is positioned by the spring pin 10. Each empty paper tape disc clamping mechanism is an independent entity, and each empty paper tape material disc 2 is correspondingly equipped with a set of empty paper tape disc clamping mechanisms. The empty paper tape material disc 2 includes a material disc inner ring rotatably mounted on the sleeve body 34.

The left and right sides of the material disc inner ring are integrally formed with a left disc and a right disc. The empty paper tape 6 is wound around the material disc inner ring and clamped between the left and right discs. After the spring pin 10 is inserted into the working position of the empty paper tape material disc 2 and the round nut 12 is tightened, the glass fiber plate disc 11 and the adjusting washer 13 apply a certain clamping force to the empty paper tape material disc 2, and the clamping force prevents the empty paper tape material disc 2 from rotating too fast, and at the same time positions and fixes the outlet direction of the empty paper tape 6. The spring pin 10 is inserted into the positioning hole on the main shaft 7 to limit the left side of the glass fiber plate disc 11. The spring pin 10 includes an L-shaped connecting plate 17, one end of which is provided with upper and lower through holes for the pin 16 to pass through, and a spring 15 is installed between the upper and lower through holes. The pin 16 passes through the upper and lower through holes and the spring 15, and a pull ring 14 is provided on the upper end of the pin 16. Pulling the pull ring 14 can pull the pin 16 out of the positioning hole of the main shaft 7, or push the pull ring 14 downward to insert the pin 16 into the positioning hole of the main shaft 7, so as to realize the position replacement of the empty paper tape material disc 2 on the main shaft 7. When replacing the empty paper tape material tray 2, only the spring pin 10 needs to be pulled out, and the empty paper tape material tray 2 can be moved between different workstations to realize the rapid replacement of the empty paper tape material tray 2. The middle of the main shaft 7 is the working position, the right side is the preparation position for placing a number of spare empty paper tape material trays 2, and the left side is the empty tray position for placing the used empty trays. The spare empty paper tape material trays 2 are moved forward to the working position one by one to complete the rapid replacement of the empty paper tape material tray 2. The rapid replacement can be completed within one minute, which is conducive to the continuous operation of the equipment and saves the time occupied by the replacement of the equipment.

[0024] The empty paper tape tensioning mechanism 4 includes a mounting base plate 24, which is a long strip. The mounting base plate 24 is vertically welded to the position of the working position of the frame 1 corresponding to the empty paper tape material tray 2. Three guide wheel mounting seats 26 are welded on the mounting base plate 24 from top to bottom in sequence. The tertiary guide wheel 20, the secondary guide wheel 19 and the primary guide wheel 18 are rotatably mounted on the guide wheel mounting seats 26 in sequence from top to bottom. The tertiary paper tape guide wheel is used for directional conveying of the empty paper tape 6, and has an anti-bias limiting function for the empty paper tape 6. A hot pressing mechanism 22 and a photoelectric switch 25 are arranged from top to bottom on the mounting base plate 24 between the secondary guide wheel 19 and the primary guide wheel 18.

The upper hot pressing plate and the lower hot pressing plate are constant temperature silicone rubber heating plates. The hot pressing mechanism 22 is used to preheat the empty paper tape 6 and heat the bonding joint of the empty paper tape 6. The electromagnetic damping wheel 21 is fixedly mounted on the mounting base plate 24 through a frame. The electromagnetic damping wheel 21 is located outside the tertiary guide wheel 20 and the secondary guide wheel 19. The electromagnetic damping wheel 21 is close to the tertiary guide wheel 20 and the secondary guide wheel 19. After the empty paper tape 6 passes through the first-level guide wheel 18, the photoelectric switch 25, the hot pressing mechanism 22, the second-level guide wheel 19, the electromagnetic damping wheel 21 and the third-level guide wheel 20 in sequence, it is transported to the empty paper tape pressing mechanism 5 through the fourth-level guide wheel 27 and the fifth-level guide wheel 28. The fourth-level guide wheel 27 and the fifth-level guide wheel 28 are fixedly installed on the frame 1 through the guide wheel mounting seat 26. The fourth-level guide wheel 27 and the fifth-level guide wheel 28 are horizontally arranged and higher than the third-level guide wheel 20.

[0026] The head and tail ends of the empty paper tape clamping mechanism 5 are respectively installed with a laser rangefinder 1, which detects the distance of the paper pad 35 in real time. 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.

[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.

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.

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 discharge inlet end of the straight-vibrating long plate 67. The spacing between the horizontal plate of the height paddle 72 and the straight-vibrating long plate 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 plate 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 (storage bin) at the bottom of the bucket elevator 38 at one time. The control system controls the linkage start and stop of multiple devices, and detects the material level in the vibrating plate 41 in real time. When the material level reaches a 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 been 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.

[0045] The automatic glue spraying device for paper pads is provided with a device bracket, on which a servo motor 2 78, a mounting plate 80, a linear guide rail 91 and a synchronous pulley cover 93 are fixedly installed, the rotating shaft of the servo motor 2 78 passes through the synchronous pulley cover 93 and is rotatably connected to the synchronous pulley cover 93 through a bearing 1, the ball screw 92 is arranged parallel to the rotating shaft of the servo motor 2 78, the rear end of the ball screw 92 passes through the synchronous pulley cover 93 and is rotatably connected to the synchronous pulley cover 93 through a bearing 2, the rotating shaft of the servo motor 2 78 and the rear end of the ball screw 92 are rotatably connected through a synchronous belt, and the ball screw 92 is driven to rotate by the servo motor 2 78. The front end of the ball screw 92 passes through the mounting plate 80 and is rotatably connected to the mounting plate 80 through the bearing 3. 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. After the glue spraying valve 82 automatically sprays glue on the neatly arranged paper pads 35 on the direct vibration conveying mechanism 43, the positioning pushing mechanism pushes the paper pads 35 onto the heat-resistant rubber plate on the outer periphery of the electric turntable, with the side of the paper pads 35 sprayed with glue facing upward.

[0048] The automatic glue spraying device for paper pads of the embodiment of the present invention is also equipped with an ultrasonic cleaning machine, which is an existing product. Before statutory holidays or long-term shutdown, the glue spraying nozzle, striker, sealing ring and other parts of the glue spraying valve 82 are removed for deep cleaning to ensure the normal operation of the equipment after the holiday. The glue spraying nozzle, striker and sealing ring and other parts are parts that are in direct contact with the glue liquid, and the glue liquid is prone to solidification.

The air volume and temperature of the heating fan 94 can be adjusted and accurately controlled. It has dual temperature control and over-temperature alarm. The temperature is controlled below 90°C to avoid risks such as over-temperature aging. The heating fan 94 is equipped with a filtering and purification device to prevent air impurities from contaminating the product.

[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.

[0052] The fully automatic bonding method for coil oil channel gasket strips provided in the embodiment of the present invention has the following conventional process flow: 1. Clean and prepare the equipment: put a certain amount of paper cushion blocks 35 into the storage bin of the bucket elevator 38, and inject a certain amount of glue into the glue storage barrel; install several empty paper trays 6 on the main shaft 7, and install the finished product winding reel on the finished product winding mechanism.

Test run for one week. Fix the end of the oil channel pad of the finished coil to the finished product reel of the finished product winding mechanism. Check that the glue between the paper pad 35 and the empty paper tape 6 does not overflow or leak and is firmly bonded. The equipment is ready.

[0056] 5. Automatic operation. The operator presses the work button, and the control system automatically controls the production process without manual operation.

[0057] 6. Empty paper tape releasing and pressing device: The empty paper tape tensioning mechanism provides a certain tensioning force. The empty paper tape 6 is automatically released as the empty paper tape material tray 2 rotates, and is directed to the pressing roller group through the five-stage guide wheel.
