Description

Technical Field

[0001] This utility model relates to the field of bakelite board production, specifically a feeding device for bakelite board production. Background Technology

[0002] Bakelite board, also known as phenolic laminate or phenolic paperboard, is a type of board made using high-quality bleached wood pulp paper and cotton linter paper as reinforcement, and high-purity, fully synthetic petrochemical raw materials reacted to produce phenolic resin as the adhesive. Bakelite board has good mechanical strength, is anti-static, and has medium electrical insulation properties. It is made by impregnating insulating paper with phenolic resin, followed by baking and hot pressing. This product is suitable for use as insulating structural components in motors and electrical equipment with high mechanical performance requirements, and can be used in transformer oil. It also has good mechanical strength and is suitable for use in PCB industry applications such as drilling pads, distribution boxes, jig plates, mold clamps, high and low voltage wiring boxes, packaging machines, and combs. It is suitable for motors, mechanical molds, PCBs, ICT jigs, forming machines, drilling machines, and table grinding pads. The feeding device used in bakelite board production is used to transport the bakelite boards, and a conveyor belt conveyor is generally used.

[0003] Existing feeding devices for bakelite board production include guide rollers to guide the bakelite boards during transport and prevent them from shifting. However, the guiding mechanisms (including guide rollers, mounting frames, etc.) of current bakelite board feeding devices are mostly integral welded or fixedly connected structures. When guide rollers experience wear, PTFE coating peeling, or shaft jamming due to long-term use, the entire guide frame (and even related components such as the conveyor belt and frame) must be disassembled to replace the damaged parts. This increases the cost of component replacement, extends maintenance time, and increases downtime costs for the company. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a feeding device for bakelite board production, so as to solve the technical problem that it is inconvenient to disassemble and replace the damaged guide rollers individually.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for bakelite board production, comprising a frame, a conveyor belt on the frame, multiple fixed seats mounted on the outer surface and back of the frame by fastening bolts, and through holes on the fixed seats, an adjusting rod inserted into the through holes, and a guide plate mounted on the end of the adjusting rod, a sliding groove on the guide plate, and multiple insert plates inserted into the sliding groove, a guide seat fixed on one side of the insert plate, and a guide roller rotatably connected to the guide seat through a rotating shaft.

[0006] By adopting the above technical solution, when the device needs to be used, the conveyor belt can be started, and then the material to be placed on the conveyor belt can be transported by the conveyor belt.

[0007] Furthermore, the insert plate has a second screw hole inside, and the top of the guide plate has a plurality of first screw holes at equal intervals. A locking bolt extending into the second screw hole is threaded into one of the first screw holes.

[0008] By adopting the above technical solution, the loosening of the insert plate in the chute is restricted by the locking bolts, thus preventing the guide roller from shifting during feeding.

[0009] Furthermore, the bottom end of the locking bolt extends to the bottom of the guide plate and is threaded with a self-locking nut, and the top of the self-locking nut is in contact with the bottom of the guide plate.

[0010] By adopting the above technical solution, the self-locking nut fits snugly against the bottom of the guide plate, offsetting the impact of feeding vibration on the bolt and further enhancing the fixing effect.

[0011] Furthermore, support frames are fixed on both sides of the bottom of the frame.

[0012] By adopting the above technical solution, the support frame can support the machine frame, thereby improving the stability of the machine frame.

[0013] Furthermore, the adjusting rod is slidably connected to the through hole.

[0014] By adopting the above technical solution, the adjusting rod can slide laterally along the through hole of the fixed base, driving the guide plate to adjust its position so as to adapt to objects of different widths.

[0015] Furthermore, the top of the fixing seat is threadedly connected to a clamping bolt extending into the through hole, and the bottom end of the clamping bolt contacts the adjusting rod.

[0016] By adopting the above technical solution, after the adjusting rod is adjusted to the correct position, the tightening bolt is tightened to hold the adjusting rod in place, preventing the adjusting rod from slipping during feeding.

[0017] Furthermore, the guide roller is fitted with a rubber sleeve made of polyurethane material, and the surface of the rubber sleeve is coated with a PTFE coating, and the thickness of the rubber sleeve is 5mm.

[0018] By adopting the above technical solution, the polyurethane-coated sleeve (Shore hardness 85A) is soft, avoiding scratches on objects, thereby improving the protective effect on objects.

[0019] Furthermore, the guide roller, guide seat, and insert plate are all detachably connected to the guide plate.

[0020] By adopting the above technical solution, the guide roller, the guide seat and the insert plate can be conveniently disassembled, so that the guide roller can be replaced.

[0021] Further, the insert plate is arranged in a "convex" shaped structure, and the insert plate and the guide seat are integrally formed.

[0022] By adopting the above technical solution, the insert plate with the "convex" shaped structure can be prevented from slipping out of the sliding groove, and the stability of the insert plate inserted into the sliding groove is improved.

[0023] In summary, the present utility model mainly has the following beneficial effects: 1. According to the present utility model, by providing the insert plate, the sliding groove, the first screw hole and the second screw hole, the insert plate can be longitudinally slid to adjust the spacing between the guide rollers to adapt to bakelite plates of different sizes, and the number of the guide rollers can be increased or decreased according to the size of the bakelite plate, so that one set of device can meet the production requirements of various bakelite plate specifications, thereby improving the applicability; and when components such as the guide roller are damaged, they can be replaced separately without replacing the entire guide mechanism, thereby saving replacement costs; 2. The insert plate of the present utility model is integrally formed with the guide seat, and the anti-falling design of the "convex" shaped insert plate enhances the structural strength, avoiding deformation or falling off of components during long-term operation. By providing the self-locking nut and the locking bolt, the locking bolt restricts the looseness of the insert plate in the sliding groove, preventing displacement of the guide roller during feeding, and the self-locking nut is attached to the bottom of the guide plate to counteract the influence of feeding vibration on the bolt, further strengthening the fixing effect.

The conveyor belt 3 is electrically connected to an external control box to control its start and stop. Multiple mounting seats 4 are installed on the outer surface and back of the frame 1 using fastening bolts. Each mounting seat 4 has a through hole 6, into which an adjusting rod 5 is inserted. A guide plate 8 is mounted at the end of the adjusting rod 5. A sliding groove 9 is provided on the guide plate 8, into which multiple insert plates 10 are inserted. A guide seat 15 is fixed to one side of each insert plate 10. The guide roller 16 is rotatably connected to the inside of the 5 via a rotating shaft. When the device is to be used, the conveyor belt 3 can be started, and the material to be placed on the conveyor belt 3 can be conveyed by the conveyor belt 3. The insert plate 10 has a second screw hole 14 inside, and the top of the guide plate 8 has a plurality of first screw holes 13 equidistantly opened. A locking bolt 11 extending into the second screw hole 14 is threaded into one of the first screw holes 13. The locking bolt 11 restricts the loosening of the insert plate 10 in the slide 9 and prevents the guide roller 16 from displacing when feeding.

[0029] See Figures 1-8the adjusting rod 5 is slidably connected with the through hole 6, the adjusting rod 5 can slide transversely along the through hole 6 of the fixing base 4, driving the guide plate 8 to adjust its position so as to adapt to objects of different widths. The outer side of the guide roller 16 is equipped with a rubber-coated sleeve made of polyurethane material, the surface of the rubber-coated sleeve is coated with a PTFE coating, and the thickness of the rubber-coated sleeve is 5mm. The polyurethane rubber-coated sleeve (Shore hardness 85A) is soft, which avoids scratching the object, thereby improving the protection effect on the object. The guide roller 16, the guide seat 15 and the insert plate 10 are all detachably connected with the guide plate 8, which facilitates the disassembly of the guide roller 16, the guide seat 15 and the insert plate 10, so that the guide roller 16 can be replaced. The insert plate 10 is arranged in a "convex" structure, and the insert plate 10 and the guide seat 15 are integrally formed. The insert plate 10 with the "convex" structure can prevent it from slipping out of the sliding groove 9, and improve the stability of the insert plate 10 inserted into the sliding groove 9. Support frames 2 are fixed on both sides of the bottom of the frame 1, and the support frames 2 can support the frame 1, thereby improving the stability of the frame 1.

[0030] Embodiment 2: On the basis of the above-mentioned Embodiment 1, the following structure is provided to improve the locking stability of the locking bolt 11 to the insert plate 10.

[0031] Specifically, the bottom end of the locking bolt 11 extends to the bottom of the guide plate 8 and is threadedly connected with a self-locking nut 12, and the top of the self-locking nut 12 is attached to the bottom of the guide plate 8. The self-locking nut 12 is attached to the bottom of the guide plate 8, which counteracts the influence of feeding vibration on the bolt and further strengthens the fixing effect.

[0032] Embodiment 3: On the basis of the above-mentioned Embodiment 1, the following structure is provided to improve the stability of the adjusting rod 5 and prevent it from moving arbitrarily.

[0033] Specifically, the top of the fixing base 4 is threadedly connected with a tightening bolt 7 extending into the through hole 6, and the bottom end of the tightening bolt 7 is in contact with the adjusting rod 5. After the adjusting rod 5 is adjusted in place, the tightening bolt 7 is tightened to press against the adjusting rod 5, preventing the adjusting rod 5 from sliding during feeding.

[0034] The working principle of the utility model is as follows: First, before use, the staff can loosen the tightening bolt 7 on the top of the fixing base 4, push the adjusting rod 5 to slide transversely along the through hole 6 of the fixing base, drive the guide plate 8 to move to a position matching the width of the object, then tighten the tightening bolt 7 to press the adjusting rod 5 to fix its position, then loosen the locking bolt 11 on the guide plate 8 and the self-locking nut 12 at the bottom, push the insert plate 10 to slide longitudinally along the sliding groove 9 of the guide plate 8, drive the guide seat 15 and the guide roller 16 to adjust the spacing, then pass the locking bolt 11 through the first screw hole 13 of the guide plate 8 and the second screw hole 14 of the insert plate, tighten the locking bolt 11 and screw the self-locking nut 12 to fix the position of the insert plate 10 and prevent loosening; Next, start the conveyor belt 3 on the frame 1, place the object at the input end of the conveyor belt 3, and the object moves towards the output end as the conveyor belt 3 rotates. Meanwhile, the guide rollers 16 on both sides rotate flexibly with the object under the action of the rotating shaft, and reduce the wear of the object's edge by replacing sliding friction with rolling friction. At the same time, the polyurethane coating of the guide rollers 16 prevents scratching the surface of the object, and the adjusted guide rollers 16 can limit the lateral displacement of the object, so that the object is conveyed along the preset path and avoids deviation. When the rubber coating of the guide roller 16 wears off, the PTFE coating peels off, or the parts are damaged, the locking bolt 11 and the self-locking nut 12 can be loosened, and the insert plate 10 and the connected guide seat 15 and guide roller 16 can be removed for replacement or cleaning. After maintenance, the parts can be reinstalled and adjusted to restore operation.
