Abstract

This application relates to a raw material feeding mechanism and method for preparing insulating tape. The method includes: an equipment support frame; a first plate is fixedly installed at the upper end of the equipment support frame; a second plate is fixedly installed in the middle of the equipment support frame; a screw feeder is fixedly installed on the upper surface of the first plate; an anti-blocking mechanism is provided on the upper side of the first plate; a feeding mechanism is provided on the upper side of the second plate; both the first and second plates have several fixed limiting ports; the anti-blocking mechanism includes a sealing cylinder with an insertion port inside; and a feeding channel is slidably connected inside the sealing cylinder. This method allows the feeding disc and sealing cylinder to move as a whole, along with the conical channel and short channel, when bridging or blockage occurs, using the thrust generated by the accumulation of raw materials. This mechanically disturbs the blocked area, allowing some raw material to continue feeding. For minor bridging, the blockage can be directly cleared. After clearing, the spring returns to its original position, ensuring normal feeding and reducing the risk of material interruption.

Description

Technical Field

[0001] This application relates to the field of transportation technology, and in particular to a raw material feeding mechanism and feeding method for preparing insulating tape. Background Technology

[0002] The raw material feeding mechanism for the preparation of insulating tape is a mechanical device or system that continuously, stably, and quantitatively conveys raw materials such as substrates, powders, granules, and additives according to process requirements.

[0003] In the process of preparing insulating tape, in addition to the substrate and liquid adhesive, fillers such as calcium carbonate, talc, and aluminum hydroxide, as well as powder or granular additives such as rosin resin, terpene resin, carbon black, and titanium dioxide, need to be added to the adhesive mixing system. The above solid raw materials are usually continuously and quantitatively conveyed to the mixing device by feeding mechanisms such as screw feeders, loss-in-weight feeders, or vibrating feeders.

[0004] However, due to the poor flowability and irregular particle shape of powder materials, bridging, arching and blockage often occur during the actual feeding process. After the material forms a stable arch structure at the discharge port, the material below cannot be discharged normally, resulting in feeding interruption.

[0005] Once a blockage occurs, although the screw or vibrating feeder continues to operate, the output will decrease significantly or even stop completely, causing fluctuations in the proportion of solid components in the adhesive. This directly affects the viscosity of the adhesive and the uniformity of coating, resulting in quality defects in the insulating tape such as color difference, particles, and uneven adhesion.

[0006] Meanwhile, if material shortages are not detected in time, they may lead to a decrease in the continuity of subsequent production and batch stability. Therefore, bridging blockage and the resulting material shortages have become key technical challenges that the raw material feeding mechanism for insulating tape urgently needs to address.

The spring is sleeved on the outside of the telescopic rod. The outside of the limiting plate is slidably connected to the inner wall of the sliding limiting groove.

[0018] Compared with the prior art, the present invention provides a raw material feeding mechanism and feeding method for preparing insulating tape, which has the following beneficial effects: 1. By setting up an anti-blocking mechanism, this invention can use the thrust generated by the accumulation of raw materials to move the feed pan, sealing cylinder, conical channel and short channel as a whole when bridging or blockage occurs. This will mechanically disturb the blocked part, allowing some raw materials to continue to be fed. For bridging with a low degree of blockage, it can be directly cleared. After clearing, the spring returns to its original position to ensure normal feeding and reduce the risk of material interruption.

[0019] 2. By setting up a feeding mechanism, the present invention can push the raw materials into the main pipeline in a timely manner when blockage or bridging occurs, through the cooperation of an electric telescopic rod, an electric telescopic rod 1 and a pushing scraper 1, reducing the risk of material interruption.

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0024] Please see Figures 1 to 11This embodiment of a raw material feeding mechanism for preparing insulating tape includes an equipment support frame 1. A first plate 1111 is fixedly installed on the upper end of the equipment support frame 1, and a second plate 12 is fixedly installed in the middle of the equipment support frame 1. A screw feeder 2 is fixedly installed on the upper surface of the first plate 1111. The discharge port of the screw feeder 2 is connected to the upper end of the feed channel 3. The connection between the discharge port of the screw feeder 2 and the upper end of the feed channel 3 is existing technology and will not be described in detail here, and is not shown in the figure. An anti-blocking mechanism 4 is provided on the upper side of the first plate 1111, and a feeding mechanism 5 is provided on the upper side of the second plate 12. Several fixed limiting ports 11111 are opened on both the first plate 1111 and the second plate 12. The anti-blocking mechanism 4 includes a sealing cylinder 41, and an insertion port 411 is opened inside the sealing cylinder 41. A feed channel 3 is slidably connected inside the sealing cylinder 41. One end of the feed channel 3 extends into the interior of the sealing cylinder 41, and a feed plate 31 is fixedly installed at the other end of the feed channel 3. The feed plate 31 can cooperate with the interior of the sealing cylinder 41. When there is blockage or bridging, the raw material accumulates and becomes compacted. At this time, the raw material pushes the feed plate 31, causing the feed plate 31 to move and thus moving the sealing cylinder 41. Several diversion ports 33 are opened around the feed plate 31 to divert the raw material and ensure uniform feeding. In the event of blockage or bridging, there will be no situation where raw material accumulates on one side and there is no raw material on the other side, thus stably and accurately pushing the feed plate 31. The inner wall of the feed plate 31 A guide vane 32 is fixedly installed. The guide vane 32 diverts the raw material, and another part of the raw material moves directly downward in the feed tray 31. One end of the guide vane 32 is fixedly connected to one side of the diversion port 33. A conical channel 45 is fixedly installed at the lower end of the sealing cylinder 41. A small short channel 46 is fixedly connected to the end of the conical channel 45 away from the sealing cylinder 41. A limiting mechanism 10 is provided inside the small short channel 46. The conical channel 45 and the small short channel 46 can break the blockage and bridging state, so that some raw materials can continue to be fed or even raw materials with a low degree of blockage can be directly cleared. Therefore, the movement of the conical channel 45 and the small short channel 46 can achieve the purpose of clearing. The limiting mechanism 10 includes a limiting opening 105 extending through one side of the short track 46 and a sliding limiting groove 106 inside the short track 46. Two symmetrically distributed telescopic rods 104 and a spring 103 are fixedly installed on the inner wall of the sliding limiting groove 106. The ends of the spring 103 and the telescopic rods 104 away from the inner wall of the sliding limiting groove 106 are fixedly connected to a limiting plate 101. The spring 103 is sleeved on the outside of the telescopic rods 104. The outer side of the limiting plate 101 is connected to the sliding limiting groove 106. The inner wall is slidably connected. A magnet 102 is fixedly installed on the side of the limiting plate 101 near the outside of the small short channel 46. A magnet six is ​​installed on the lower side of the connection between the feeding inclined channel 8 and the vertical cylinder 6. The magnets and magnet 102 have opposite magnetic properties. Therefore, when the sealing cylinder 41 moves, the small short channel 46 moves, and magnet 102 moves and attracts magnet six. The magnetic force is greater than the upward movement and the force of spring 103. At this time, the limiting plate 101 slides downward on the inner wall of the sliding limiting groove 106. At this time, some raw materials enter the inside of the feeding inclined channel 8. The limiting port 105 is connected to the sliding limiting groove 106. A pre-storage cylinder 9 is slidably connected to the inner wall of the insertion port 411. Several pre-storage limiting grooves 91 are opened around the periphery of the pre-storage limiting grooves 91. Guide slide rods 44 are fixedly installed on the inner walls of the pre-storage limiting grooves 91 on opposite sides. A slider 43 is slidably installed on the outer side of the guide slide rods 44. A spring 42 is fixedly installed on one side of the slider 43. The side of the spring 42 away from the slider 43 is fixedly connected to the inner wall of the pre-storage limiting groove 91. The side of the slider 43 is fixedly connected to the inner wall of the insertion port 411. Therefore, when the sealing cylinder 41 moves, the spring... 42 begins to contract or expand, so that after the unblocking is completed, the spring 42 can reset the sealing cylinder 41. The feeding mechanism 5 includes a sealing fixing body 51, an electric telescopic rod 52, and an electric telescopic rod 53. The upper end of the sealing fixing body 51 is fixedly installed with a controller, a buzzer, and a distance sensor. When the sealing cylinder 41 moves, the controller controls the electric telescopic rod 52 and the electric telescopic rod 53 to run, and the buzzer alarms in case of blockage or bridging. The controller, buzzer, and distance sensor are existing technologies and will not be described in detail here. One end of the electric telescopic rod 52 and one end of the electric telescopic rod 53 are fixedly connected to the inner wall of the sealing body 51. The inner walls of the electric telescopic rod 52 and one end of the electric telescopic rod 53 away from the sealing body 51 are respectively fixedly connected to the pushing scraper 541 and the pushing scraper 54. The electric telescopic rod 52 and one end of the electric telescopic rod 53 are existing technologies and will not be described in detail here. The upper ends of the pushing scraper 54 and the pushing scraper 541 are respectively fixedly installed with the extrusion body 55 and the extrusion body 551. The extrusion body 55 and the extrusion body 551 are respectively provided with the extrusion inclined surface 56 and the extrusion inclined surface 561 on one side. The extrusion inclined surface 56 and the extrusion inclined surface 561 are adapted to the pressure inclined surface 112, thereby reducing friction. The pushing scraper 54 and the pushing scraper 541 are respectively fixedly installed with the sliding directional slider 5711 on one side. The outer side of the sliding directional slider 5711 is slidably connected to the inner wall of the sliding limiting groove 572. A feeding cylinder 57 is fixedly connected to one side of the sealing and fixing body 51. The feeding cylinder 57 has two symmetrically distributed sliding guide grooves 571 inside. The inner wall of the sliding guide groove 571 has a sliding limiting groove 572. The end of the feeding cylinder 57 away from the sealing and fixing body 51 is fixedly connected to the connecting channel 7. An inclined elastic baffle 71 is fixedly installed on the inner wall of the connecting channel 7. When the raw material falls, the inclined elastic baffle 71 ensures that the raw material falls along the inclined surface. There is only one inclined elastic baffle 71 to avoid multiple inclined elastic baffles 71 causing blockage and aggravation. The weight of the falling material can make the inclined elastic baffle 71 shake slightly, further accelerating the speed at which the raw material falls on its surface. A vertical cylinder 6 is fixedly connected to the upper end of the connecting channel 7. Several symmetrically distributed fixed limiting blocks 61 are fixedly installed on the outer side of the vertical cylinder 6. The fixed limiting blocks 61 are engaged with the fixed limiting port 11111. A feeding ramp 8 is fixedly installed on one side of the vertical cylinder 6. Two magnets 115 are fixedly installed inside the feeding ramp 8. An orientation mechanism 11 is provided inside the feeding ramp 8. The orientation mechanism 11 includes a rotating shaft 113 rotatably connected to the inside of the feeding ramp 8. A limiting plate 117 for limiting the position of the orientation rod 114 is fixedly installed on the outside of the rotating shaft 113. An orientation rotation groove 116 is opened on the outside of the rotating shaft 113. The inner walls of the orientation rotation groove 116 are rotatably connected to small rotating shafts 118 on both sides. A directional rod 114 is slidably connected to the outer side of the small rotating shaft 118. A magnet 5 is provided at the end of the directional rod 114 near the magnet 115. The magnetic poles of the magnet 115 and the magnet 5 are opposite. When the swing plate 111 is squeezed and swings, the magnet 5 on the directional rod 114 attracts one of the magnets 115, thus ensuring the stability of the position of the swing plate 111. Springs 2 119 are rotatably connected to both opposite sides of the directional rod 114. The ends of the two springs 2 119 away from the directional rod 114 are rotatably connected to the inner wall of the directional rotating groove 116. The springs 2 119 are sleeved on the outer side of the small rotating shaft 118. The swing plate 111 is fixedly connected to the outer side of the rotating shaft 113. A pressure inclined surface 112 is opened on one side of the swing plate 111. The end of the feeding inclined channel 8 away from the vertical cylinder 6 is fixedly connected to the side of the feeding cylinder 57. The end of the vertical cylinder 6 away from the connecting channel 7 is fixedly connected to the lower end of the pre-storage cylinder 9. In this embodiment, a method for feeding raw materials for preparing insulating tape includes the following steps: Step 1: Start feeding: The screw feeder 2 runs, the raw material enters the feed channel 3, some of the raw material falls on the guide plate 32, enters the diversion port 33, and enters the conical channel 45, and some raw material directly enters the interior of the conical channel 45; Step 2: Blockage or bridging occurs: The raw material pushes the feed plate 31, the feed plate 31 moves, the sealing cylinder 41 moves, the slider 43 moves, the spring 42 contracts, the conical channel 45 moves, and the short channel 46 moves. Step 3: Feeding begins: Magnet 102 and Magnet 6 attract each other, the short track 46 moves upward, the limiting plate 101 remains stationary, spring 103 contracts, and a space is created between the upper end of the limiting plate 101 and the inner side of the limiting port 105. At this time, the raw material enters the feeding ramp 8. Step 4: Replenishing materials: Electric telescopic rod 52 and electric telescopic rod 53 start to run. Electric telescopic rod 53 pushes the scraper 54 to move. The scraper 54 pushes the raw material into the replenishing cylinder 57. The sliding directional slider 5711 slides inside the sliding limit groove 572. Step 5: Switching to feeding: After the push is completed, the electric telescopic rod 53 retracts. After the push scraper 54 is reset, the electric telescopic rod 52 unfolds, and the extrusion body 551 pushes the swing plate 111. Step 6: Switching Orientation: The swing plate 111 swings, the rotating shaft 113 rotates, the orientation rod 114 rotates, the small rotating shaft 118 rotates, the limiting plate 117 limits the orientation rod 114, the orientation rod 114 swings, the small rotating shaft 118 rotates, and the orientation rod 114 moves closer to another magnet 115. Step 7: Continue feeding: The raw material enters the vertical cylinder 6 and then the connecting channel 7.
