Usually, it is fed by a feeding device, and the existing feeding device is the equipment used for feeding halogen-free flame-retardant cable material during processing and production.

[0003] Existing feeding devices, when used for feeding halogen-free flame-retardant cable materials, require the bottom end of the feeding conveyor to be directly closed with the bottom cover, and multiple bolts to be rotated and fixed using tools. This fixing process involves a large number of bolts, and the small internal space between the bottom end of the feeding conveyor and the main frame makes rotating the multiple bolts cumbersome and inconvenient. Furthermore, disassembly is inconvenient when the feeding conveyor is damaged during maintenance, affecting the ease of disassembly and maintenance when the feeding device is damaged after long-term use in feeding halogen-free flame-retardant cable materials. Therefore, this utility model proposes a halogen-free cable material feeding device. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By designing a convenient disassembly and maintenance mechanism, the bottom cover can be closed to the bottom of the feeding conveyor by engaging a retaining ring inside the retaining groove. The push block is limited and moved, and the rolling balls simultaneously press against the four inclined extrusion blocks, moving the ends of the inclined extrusion blocks and engaging them inside the retaining holes. This quickly and easily fixes the bottom cover to the bottom of the feeding conveyor.

This improves the convenience of disassembly and maintenance of the feeding device body 100 when it is damaged during long-term use of halogen-free flame-retardant cable material feeding.

[0027] In order to facilitate the quick installation of the bottom cover 104 to the bottom end of the feeding conveyor 103 by means of the snap-fit ​​assembly, in this embodiment, preferably, the snap-fit ​​assembly includes a snap ring 1042 integrally disposed at the bottom edge of the feeding conveyor 103, and a snap groove 1041 is formed on the inner surface of the bottom cover 104. The snap ring 1042 engages with the inside of the snap groove 1041, and the bottom cover 104 is closed to the bottom end of the feeding conveyor 103 for installation by snapping the snap ring 1042 into the inside of the snap groove 1041.

[0028] To facilitate the pressing and engaging of the inclined extrusion block 1044 via the rotary pushing assembly, in this embodiment, preferably, the rotary pushing assembly includes a limiting groove 1047 located at the center of the bottom cover 104. A threaded rod 1049 is threadedly rotated within the limiting groove 1047 at the center of the bottom cover 104. A pushing block 1046 is disposed inside the limiting groove 1047, allowing a wrench to engage at the bottom end of the threaded rod 1049 to rotate it. When the threaded rod 1049 rotates, it moves the pushing block 1046. The bottom end of the pushing block 1046... The top end of the threaded rod 1049 is mounted via a bearing. Limiting blocks 1040 are provided at the bottom ends of both sides of the push block 1046, thereby limiting the sliding of the push block 1046 within the limiting groove 1047 by the limiting blocks 1040. Rolling balls 1048 roll on the end surface of the push block 1046. The surface of the push block 1046 contacts the end surface of the inclined extrusion block 1044 through the rolling balls 1048. When the push block 1046 moves, the rolling balls 1048 roll into contact with the surface of the inclined extrusion block 1044, simultaneously squeezing and engaging the four inclined extrusion blocks 1044.

[0029] To facilitate the secure installation of the retaining ring 1042 after engagement using the compression reinforcement component, in this embodiment, preferably, the compression reinforcement component includes a movement control groove 1045 formed at the end edge of the limiting groove 1047. An inclined compression block 1044 is provided inside the movement control groove 1045. A retaining hole 1043 is formed on the inner surface of the retaining ring 1042. The end of the inclined compression block 1044 engages with the interior of the retaining hole 1043, allowing the inclined compression block 1044 to move within the movement control groove 1045. The end of 4 is locked and fixed inside the card hole 1043. The lower surface of the inclined extrusion block 1044 is provided with a sliding block 10441. The end of the sliding block 10441 is provided with a reset elastic block 10442 at the connection between the inner side of the moving control groove 1045. When disassembling, the pushing block 1046 can be loosened, and the reset elastic block 10442 will deform to drive the sliding block 10441 and the inclined extrusion block 1044 to slide and reset, so that the inclined extrusion block 1044 is disengaged from the inside of the card hole 1043, which facilitates the quick disassembly of the bottom cover 104.

[0030] The feeding device includes a feeding protection mechanism, which includes feeding protection components disposed on both sides inside the feeding box 102. The end of the feeding protection component is provided with a fixing component, which can guide the feeding device body 100 into the feeding box 102 when feeding and when vibration occurs, and prevent splashing during vibration.

[0031] In order to facilitate the introduction of feed material through the feed material protection component and to protect the material from vibration during feeding, preventing splashing, in this embodiment, preferably, the feed material protection component includes feed material protection plates 1023 disposed on both sides inside the feed box 102, and the feed material protection plates 1023 have a sloping structure, so that the material can be fed in through the upper surface of the feed material protection plates 1023, and after feeding, the material can be protected by the lower surface of the feed material protection plates 1023 during feeding vibration to prevent vibration splashing.

[0032] To facilitate the fixed installation of the feed guide plate 1023 via the fixing assembly, in this embodiment, preferably, the fixing assembly includes a fixing plate 1021 integrally disposed at the end of the feed guide plate 1023. A fixing bolt 1022 is rotatably mounted inside the fixing plate 1021. The feed guide plate 1023 is fixed to the inner side of the feed box 102 via the fixing plate 1021 and the fixing bolt 1022. The feed guide plate 1023 can be closed inside the feed box 102 by the fixing plate 1021, and the fixing plate 1021 and the feed guide plate 1023 can be fixedly installed by rotating the fixing bolt 1022.

[0033] The working principle and usage process of this utility model: When using this halogen-free cable material feeding device, the main body 100 of the feeding device is placed at the usage position by directly contacting the ground through the main frame 101. After the main body 100 of the feeding device is placed, the feeding conveyor 103 operates in the conveyor belt to feed the material into the feeding box 102. The material is fed from the bottom end of the feeding box 102 into the feeding conveyor 103 and conveyed to the top and discharged through the discharge pipe 105. The material is then discharged through the discharge pipe 105 into the equipment for processing halogen-free flame-retardant cable materials.

[0034] Then, when the main body 100 of the feeding device is feeding material into the inside of the feeding box 102, the halogen-free flame-retardant cable material falls directly onto the surface of the feeding guide plate 1023 and falls to the bottom of the inside of the feeding box 102, which facilitates slow feeding. At the same time, when the equipment vibrates during operation, the feeding guide plate 1023 can protect the halogen-free flame-retardant cable material entering the inside. The halogen-free flame-retardant cable material is also elastic, which prevents the halogen-free flame-retardant cable material inside from splashing to the outside when vibration occurs, thus improving the feeding device main body 100's effect of guiding and protecting the halogen-free flame-retardant cable material inside the feeding box 102 during feeding.

[0035] Finally, before the main body 100 of the feeding device is used, the bottom cover 104 can be closed to the bottom end of the feeding conveyor 103 by engaging the retaining ring 1042 inside the retaining groove 1041. After closing, the wrench is engaged at the end of the threaded rod 1049 to drive the threaded rod 1049 to rotate. When the threaded rod 1049 rotates, it drives the push block 1046 to move within the limiting groove 1047 and is limited by the limiting block 1040. When the push block 1046 moves, it rolls through the ball bearings 1048 to simultaneously squeeze the four inclined extrusion blocks 1044, and drives the inclined extrusion blocks 1044 to move within the movement control groove 1045 until the end of the inclined extrusion block 1044 is engaged in the retaining hole 1043. The internal retaining ring 1042 is reinforced to quickly and securely install the bottom cover 104 to the bottom end of the feeding conveyor 103, making installation between the bottom cover 104 and the feeding conveyor 103 convenient. When the feeding device body 100 is damaged during long-term feeding and needs repair, the push block 1046 is loosened by rotating the reverse operation. The reset elastic block 10442 deforms and drives the sliding block 10441 and the inclined extrusion block 1044 to slide and reset, so that the inclined extrusion block 1044 disengages from the inside of the retaining hole 1043, making it easy to quickly disassemble the bottom cover 104. The disassembly and assembly are convenient, improving the convenience of disassembly and repair when the feeding device body 100 is damaged during long-term feeding of halogen-free flame-retardant cable materials.
