Description

Technical Field

[0001] This utility model relates to the field of cable production technology, specifically to a cable reel mounting mechanism for an extruder. Background Technology

[0002] Extruders, also known as plastic extruders, are one of the core pieces of equipment in the field of plastic molding and processing. They occupy an important position in modern industrial production, especially in industries such as cable production, pipe manufacturing, and profile processing. In cable production, they are usually equipped with cable reel mounting mechanisms at the rear to carry and release semi-finished or finished cables.

[0003] Patent publication number CN108724668A discloses a cable reel installation device for an extruder, belonging to the field of cable production technology. This device allows for the installation of cable reels in either a 7-shaped space formed by the interconnection of a first and second cable reel baffle, or a 7-shaped space formed by the interconnection of a third and fourth cable reel baffle, depending on the reel specifications. Removing the third and fourth cable reel baffles and the pads does not affect the use of the cable reel installation structure composed of the first and second cable reel baffles and the track guard plate. This significantly improves the utilization rate of the cable reel installation device, ensuring continuous production of the extruder and reducing cable production costs. It also solves the problems of wasted time and manpower, and poor safety and reliability, when installing cable reels with outer diameters of Ф500-Ф800 on the Ф70 extruder's take-up and cable-laying machine.

[0004] The aforementioned patent achieves the placement and fixation of cable reels of different sizes by welding the first cable reel baffle, the second cable reel baffle, the third cable reel baffle, and the fourth cable reel baffle at different positions. However, once the structure is welded, it cannot be quickly adjusted according to the size of the cable reel, which makes it inconvenient in actual use. Furthermore, the baffles support the cable reel, resulting in high friction and preventing the cable reel from rotating, thus making it impossible for the cable to complete the winding and unwinding tasks freely.

[0005] Therefore, this utility model provides a cable reel mounting mechanism for extruders. Utility Model Content

[0006] To address the problem that welded fixed structures cannot be quickly adjusted according to the size of the cable reel, and that their baffle support method causes high friction, resulting in inflexible rotation of the cable reel and seriously affecting cable winding and unwinding operations, the purpose of this utility model is to provide a cable reel installation mechanism for extruders.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cable reel mounting mechanism for an extruder, comprising a frame, wherein two symmetrically distributed sliding rods are fixedly mounted on the middle of opposite sides of the two frames, and an assembly mechanism is provided in the middle of the two frames for mounting the cable reel. The assembly mechanism includes: The adjustment assembly includes two movable frames slidably mounted in the middle of the sliding rod. Two symmetrically distributed movable seats are slidably mounted on the upper part of each of the two movable frames. A first double-ended screw is rotatably mounted on the lower part of each of the two movable frames. The lower parts of multiple movable seats are threaded onto the upper part of the first double-ended screw. Limit rollers are rotatably mounted on the upper part of multiple movable seats. Fixed frames are fixedly mounted at both ends of the two sliding rods. A second double-ended screw is rotatably mounted in the middle of each of the two fixed frames. Sliding frames are fixedly mounted on one side of each of the two movable frames. The middle parts of the two sliding frames are threaded onto the middle of the second double-ended screw. A limiting component, located on one side of the movable frame, is used to limit the side of the cable reel.

[0008] Preferably, the limiting component includes a limiting frame fixedly installed on one side of the movable frame, a telescopic seat slidably engaged at the middle of the opposite sides of the two limiting frames, a buffer spring fixedly installed at the middle of one side of the two telescopic seats, and the other ends of the multiple buffer springs fixedly installed at the middle of one side of the limiting frame.

[0009] Preferably, a rotating disk is rotatably mounted on each of the two telescopic seats on opposite sides, and anti-slip textures are provided on the opposite sides of the two rotating disks.

[0010] Preferably, a telescopic rod is fixedly installed in the middle of each of the two limiting frames, and the other end of each telescopic rod is fixedly installed in the middle of one side of the telescopic seat.

[0011] Preferably, a handle is fixedly installed at one end of both the No. 1 double-ended screw and the No. 2 double-ended screw, and the outer circumferential surface of both handles is covered with an anti-slip sleeve.

[0012] Preferably, two symmetrically distributed vibration damping pads are fixedly installed at the bottom of each of the two frames, and the four vibration damping pads are symmetrically distributed. The vibration damping pads are rubber pads with anti-slip textures on their bottom. Beneficial effects

[0013] This utility model provides a cable reel mounting mechanism for an extruder. Compared with the prior art, it has the following advantages: 1. This application allows operators to drive the No. 1 and No. 2 double-headed screws to rotate simply by turning a handle. The rotation of the No. 1 double-headed screw drives the moving seat and the limiting roller to move horizontally to accommodate cable reels of different diameters. The rotation of the No. 2 double-headed screw drives the entire moving frame to slide along the sliding rod to accommodate cable reels of different widths. This design enables rapid and precise bidirectional adjustment of the cable reel's installation position. It is highly versatile, easy to operate, and significantly improves installation efficiency and adjustment accuracy. Furthermore, by setting the limiting roller, the cable reel can reduce friction after installation, enabling rapid cable winding and unwinding.

[0014] 2. This application achieves a tight fit between the rotating disc and the cable reel side plate under the thrust of the buffer spring. The anti-slip texture provides sufficient static friction. When the cable reel rotates, the rotating disc rotates accordingly, transforming sliding friction into rolling friction. This effectively reduces friction loss and surface scratches caused by traditional fixed limiters, protecting the cable reel while ensuring its stability and reliability during rotation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4This utility model provides a technical solution: a cable reel mounting mechanism for an extruder, including a frame 1. The frame 1 has two symmetrically distributed sliding rods 211 fixedly installed at the center of opposite sides of the two frames 1. The sliding rods 211 are made of high-strength carbon steel with a chrome-plated surface, and their outer diameter accuracy reaches IT6 level, ensuring that the straightness error of the moving frame 212 during sliding does not exceed 0.05mm. An assembly mechanism 2 is provided at the center of the two frames 1 for installing the cable reel. The assembly mechanism 2 includes: The adjusting assembly 21 includes two movable frames 212 slidably mounted in the middle of the sliding rod 211. The movable frames 212 are made of T6 heat-treated aluminum alloy profiles. Two symmetrically distributed movable seats 214 are slidably mounted on the upper part of each of the two movable frames 212. A first double-ended screw 213 is rotatably mounted on the lower part of each of the two movable frames 212. The lower parts of multiple movable seats 214 are threaded onto the upper part of the first double-ended screw 213. Limit rollers 215 are rotatably mounted on the upper part of each of the multiple movable seats 214. The outer surface of the limit rollers 215 is machined with a depth of 3. The roller body has a V-shaped groove of mm and is equipped with a double-row deep groove ball bearing. The two ends of the two sliding rods 211 are fixedly mounted with a fixed frame 216. The middle of the two fixed frames 216 is rotatably mounted with a second double-ended screw 217. The two movable frames 212 are fixedly mounted with a sliding frame 218 on one side. The middle of the two sliding frames 218 is threadedly mounted on the middle of the second double-ended screw 217. The two ends of the first double-ended screw 213 and the second double-ended screw 217 are mounted in the middle of the movable frame 212 and the fixed frame 216 through deep groove ball bearings. The limiting component 22 is disposed on one side of the movable frame 212 and is used to limit the side of the cable reel.

[0022] The limiting assembly 22 includes a limiting frame 221 fixedly installed on one side of the movable frame 212. A telescopic seat 222 is slidably attached to the middle of the opposite side of the two limiting frames 221. A buffer spring 224 is fixedly installed on the middle of one side of the two telescopic seats 222. The other end of the multiple buffer springs 224 is fixedly installed on the middle of one side of the limiting frame 221.

[0023] Two telescopic seats 222 are each rotatably mounted on opposite sides of a rotating disk 223. The opposite sides of the two rotating disks 223 are provided with anti-slip textures. By creating anti-slip textures, the rotating disk 223 can make close contact with the side plate of the cable reel and rotate with it during rotation, reducing friction loss. At the same time, it can limit and fix the two sides of the cable reel, ensuring its rotational stability.

[0024] Telescopic rods 225 are fixedly installed in the middle of both limit brackets 221. The other end of each telescopic rod 225 is fixedly installed in the middle of one side of the telescopic seat 222. The telescopic rods 225 can prevent the spring from tilting when it is compressed, which would damage the buffer spring 224.

[0025] A handle 2131 is fixedly installed at one end of both the No. 1 double-ended screw 213 and the No. 2 double-ended screw 217. The outer circumferential surface of both handles 2131 is covered with an anti-slip sleeve. The surface of the anti-slip sleeve is designed with raised dot patterns and the coefficient of friction is not less than 0.8, which allows the operator to easily turn the handle 2131 to drive the No. 1 double-ended screw 213 and the No. 2 double-ended screw 217 to rotate.

[0026] Two symmetrically distributed vibration damping pads 11 are fixedly installed at the bottom of each of the two racks 1, and the four vibration damping pads 11 are symmetrically distributed. The vibration damping pads 11 are rubber pads with anti-slip textures on the bottom to reduce the vibration generated when the cable reel rotates.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0028] During operation, when the cable reel needs to be installed, the operator first drives the first double-ended screw 213 and the second double-ended screw 217 to rotate by turning the handle 2131. For the first double-ended screw 213, its forward and reverse rotation will drive the threaded movable seat 214 to slide in the horizontal direction towards or away from each other on the movable frame 212, thereby adjusting the axial spacing of the limit roller 215 to adapt to the different thicknesses of the cable reel. At the same time, when the second double-ended screw 217 is rotated, since the sliding frame 218 is threadedly connected to the middle of the second double-ended screw 217, and the fixed frame 216 is fixed at both ends of the movable frame 212, the two movable frames 212 can be driven to move towards or away from each other along the sliding rod 211 to adjust the length of the cable reel and ensure that the diameter of the entire assembly mechanism 2 matches the span of the cable reel. At this time, the two side plates of the cable reel can be placed in the middle groove of its limiting roller 215. When the cable reel rotates, it will drive its limiting roller 215 to rotate, thereby reducing the damage caused by friction and ensuring that the cable reel can freely retract and extend the cable. After the cable reel is placed on its limiting roller 215, the rotating disk 223 is located in the middle of the two side plates of the cable reel. With the cooperation of the buffer spring 224, the two rotating disks 223 can be tightly attached to their side plates to limit the side plates, ensuring that the rotation of the limiting disk is always in a stable state and reducing the shaking generated during rotation.
