Description

Technical Field

[0001] This utility model belongs to the field of cable raw material conveying technology, specifically relating to a raw material conveying device for cable material manufacturing. Background Technology

[0002] Cable raw materials refer to various materials used in the manufacture of cables, such as polyvinyl chloride (PVC), cross-linked polyethylene (XLPE), and rubber. They are mainly used to manufacture the outer protective layer of cables. In the manufacturing process of cable materials, special raw material conveying devices are usually required to ensure smooth production.

[0003] Existing raw material conveying devices for cable material manufacturing typically employ auger conveyors. These devices transport raw materials by feeding them into a hopper and then using a rotating auger. Although auger conveyors can generally meet the needs of raw material conveying, some problems still exist in actual operation. Raw materials are prone to arching and accumulation at the discharge port of the hopper, which leads to poor material flowability. Arching and accumulation may eventually cause the raw materials to block the discharge port, affecting production efficiency and quality. Utility Model Content

[0004] In view of this, the present invention provides a raw material conveying device for cable material manufacturing. Through the anti-blocking mechanism, the raw material can be effectively loosened to ensure the flowability of the cable material and prevent the raw material from bridging and accumulating at the discharge port, thus further enhancing the anti-blocking effect. Through this continuous and stable action, the blockage problem of the raw material during the conveying process is effectively prevented.

[0005] To solve the above-mentioned technical problems, this utility model provides a raw material conveying device for cable material manufacturing, including an auger conveyor and a hopper at its inlet, and an anti-blocking mechanism inside the hopper. The anti-blocking mechanism is used to prevent cable raw materials from clogging at the outlet of the hopper. The anti-blocking mechanism includes a fixed plate inside the hopper cavity, a rotating groove at the lower end of the fixed plate, a rotating cylinder rotatably connected within the groove, a sliding groove on the outer arc surface of the rotating cylinder, and a material feeding head slidably connected within the sliding groove. The fixed plate also has a driving component for driving the rotating cylinder to rotate. This effectively loosens the raw material, ensures the flowability of the cable raw material, prevents the raw material from bridging and accumulating at the outlet, and further enhances the anti-blocking effect. Through this continuous and stable action, the blockage problem of the raw material during the conveying process is effectively prevented.

[0006] The anti-blocking mechanism also includes a fixed rod installed in the rotating trough. The lower end of the fixed rod is equipped with a reciprocating screw. Both the fixed rod and the reciprocating screw are located inside the rotating cylinder. The reciprocating screw is threadedly connected to the threaded hole on the feeding head, which drives the feeding head to move up and down reciprocally.

[0007] The drive assembly includes a toothed ring disposed on the outer arc surface of the rotating cylinder. A gear is rotatably connected to the lower end of the fixed plate near the toothed ring. The gear meshes with the toothed ring, thus providing a rapid drive function.

[0008] The drive assembly also includes a motor mounted on the upper part of the fixed plate, and the output shaft of the motor is fixedly connected to the gear, thus providing a drive source for the gear.

[0009] The lower end of the fixed plate is equipped with a protective shell, and the gear and toothed ring are located inside the protective shell. The protective shell is provided with an opening that matches the rotating cylinder, so as to avoid interference from external impurities.

[0010] The chutes are rectangular and symmetrically distributed on the lower end of the outer arc surface of the rotating cylinder. The material feed head is slidably connected between the two chutes and slides in cooperation with the rotating cylinder, thus guiding the material feed head to move.

[0011] The middle of the feed head gradually tapers towards both ends, ensuring smoother up-and-down movement of the feed head.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. As raw materials enter the auger conveyor through the hopper, the rotating drum rotates, and the rectangular chute and the discharge head rotate synchronously with it. During rotation, the discharge head effectively loosens the raw materials, ensuring their flowability and preventing them from bridging and clogging at the outlet. Simultaneously, due to the reciprocating screw thread connection, the discharge head not only rotates with the rotating drum but also moves up and down along the rectangular chute via the reciprocating screw, further enhancing the anti-clogging effect and ensuring the raw materials smoothly pass through the hopper into the auger conveyor for subsequent processing. This continuous and stable action effectively prevents blockages during the conveying process.

[0014] 2. Start the motor, and its output shaft drives the gear to rotate. The gear drives the rotating cylinder to rotate in the groove through the toothed ring that meshes with it, thus achieving rapid driving.

[0015] 3. The entire anti-clogging mechanism is protected by a protective shell to prevent interference from external impurities, and the protective shell is provided with openings that are compatible with the rotating cylinder. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0022] This embodiment provides a raw material conveying device for cable material manufacturing, such as... Figure 1-4 The diagram shows a screw conveyor 100 and a hopper 200 located at its inlet. It also includes an anti-blocking mechanism within the hopper 200. The anti-blocking mechanism prevents cable material from clogging at the outlet of the hopper 200. The mechanism includes a fixed plate 300 within the hopper 200's inner cavity. A rotating groove 301 is located at the lower end of the fixed plate 300. A rotating cylinder 302 is rotatably connected within the rotating groove 301. The upper end of the rotating cylinder 302 is open. A sliding groove 303 is located on the outer arc surface of the rotating cylinder 302. A discharge head 304 is slidably connected within the sliding groove 303. Both ends of the discharge head 304 are longer than both ends of the sliding groove 303, preventing the discharge head 304 from exposing the sliding groove 303 when it moves up and down, thus preventing material from entering the rotating cylinder 302. The fixed plate 300 also has a drive assembly for driving the rotating cylinder 302 to rotate.

[0023] Raw materials enter the auger conveyor 100 through the hopper 200. During this process, the rotating drum 302 is driven to rotate, which in turn drives the rectangular chute 303 and the discharge head 304 to rotate synchronously. The discharge head 304 can effectively loosen the raw materials during rotation, ensuring the flowability of the cable raw materials and preventing the raw materials from bridging and clogging at the discharge port. At the same time, the discharge head 304 not only rotates with the rotating drum 302, but also moves up and down along the rectangular chute 303, thereby further enhancing the anti-clogging effect and ensuring that the raw materials can smoothly pass through the hopper 200 and enter the auger conveyor 100 for subsequent processing. Through this continuous and stable action, the problem of blockage of raw materials during the conveying process is effectively prevented.

[0024] like Figure 2-4 As shown, the anti-blocking material mechanism also includes a fixed rod 305 disposed in the rotating groove 301. The lower end of the fixed rod 305 is provided with a reciprocating screw 306. Both the fixed rod 305 and the reciprocating screw 306 are located in the rotating cylinder 302. The reciprocating screw 306 is threadedly connected to the threaded hole provided on the feeding head 304. The axes of the rotating groove 301, the fixed rod 305, the reciprocating screw 306 and the rotating cylinder 302 coincide.

[0025] Due to the threaded connection of the reciprocating screw 306, the feeding head 304 not only rotates with the rotating cylinder 302, but can also move up and down along the rectangular slide groove 303 via the reciprocating screw 306, thereby further enhancing the anti-clogging effect.

[0026] like Figure 2-4 As shown, the drive assembly includes a toothed ring 400 disposed on the outer arc surface of the rotating cylinder 302. The toothed ring 400 is fixedly disposed on the upper end of the outer arc surface of the rotating cylinder 302. A gear 401 is rotatably connected to the lower end of the fixing plate 300 near the toothed ring 400. The gear 401 meshes with the toothed ring 400.

[0027] When the gear 401 rotates, it drives the rotating cylinder 302 to rotate in the rotating groove 301 through the toothed ring 400 that meshes with it. As the rotating cylinder 302 rotates, the rectangular slide 303 and the feeding head 304 rotate synchronously, thus achieving the effect of rapid driving.

[0028] like Figure 1-4 As shown, the drive assembly also includes a motor 402 disposed on the upper end of the fixed plate 300. The output shaft of the motor 402 is fixedly connected to the gear 401. The rotation of the output shaft of the motor 402 drives the gear 401 to rotate synchronously, thereby providing a drive source for the gear 401.

[0029] like Figure 2-4 As shown, the lower end of the fixed plate 300 is provided with a protective shell 500. The gear 401 and the toothed ring 400 are located inside the protective shell 500. The protective shell 500 is provided with an opening that matches the rotating cylinder 302. The entire anti-blocking material mechanism is protected by the protective shell 500 to avoid interference from external impurities.

[0030] like Figure 2-3 As shown, the slide grooves 303 are rectangular and symmetrically distributed at the lower end of the outer arc surface of the rotating cylinder 302. The feeding head 304 is slidably connected between the two slide grooves 303 and slidably cooperates with the rotating cylinder 302, which plays a guiding role in the movement of the feeding head 304.

[0031] like Figure 2-3 As shown, the middle of the feeding head 304 gradually tapers towards both ends to ensure smoother up-and-down movement of the feeding head 304.

[0032] The working principle of the raw material conveying device for cable material manufacturing provided by this utility model is as follows: When cable raw materials need to be conveyed, the raw materials enter the auger conveyor 100 through the feed hopper 200. During this process, the motor 402 is started, and its output shaft drives the gear 401 to rotate. The gear 401 drives the rotating cylinder 302 to rotate in the rotating groove 301 through the toothed ring 400 meshing with it. As the rotating cylinder 302 rotates, the rectangular chute 303 and the feed head 304 rotate synchronously. During the rotation, the feed head 304 can effectively loosen the raw materials to ensure the cable raw materials are properly conveyed. The material flowability prevents raw materials from bridging and clogging at the discharge port. Simultaneously, due to the threaded connection of the reciprocating screw 306, the discharge head 304 not only rotates with the rotating drum 302 but also moves up and down along the rectangular chute 303 via the reciprocating screw 306, further enhancing the anti-clogging effect. The entire anti-clogging mechanism is protected by the protective shell 500, preventing interference from external impurities and ensuring that the raw materials smoothly pass through the discharge hopper 200 into the auger conveyor 100 for subsequent processing. This continuous and stable action effectively prevents blockage of the raw materials during the conveying process.

[0033] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
