Abstract
Description
Technical Field
[0001] This utility model relates to the field of drafting machine technology, specifically to a mechanical compact spinning agglomeration drafting mechanism. Background Technology
[0002] Multi-roller drawing machines are process testing instruments used in the field of polymer material processing. They are mainly used for the spinning of ultra-high molecular weight polyethylene and the stretching of packing straps. The equipment achieves a temperature control environment of no more than 350°C through a four-zone heating system. It adopts an eight-roller staggered layout and a roller gap design of 250-350mm, which effectively utilizes the residual heat of the material to improve the stretching efficiency. Its patented technologies include a conical roller head anti-drop structure, a double-sided synchronous feeding system, and a gear meshing transmission device, which solves the problems of slippage and belt breakage that exist in traditional equipment.
[0003] Multi-roller drafting machines achieve fiber stretching and aggregation through the speed difference between multiple rotating rollers. In traditional multi-roller drafting machines, the rotating rollers are often directly exposed during actual use. Utility Model Content
[0004] The present invention aims to solve the problems mentioned in the background art by providing a mechanical compact spinning and drawing mechanism.
[0005] The specific technical solution is as follows:
[0006] A mechanical compact spinning gathering and stretching mechanism includes a mounting base, a mounting plate at the bottom of the mounting base, two support rods fixedly mounted at the bottom of the mounting plate, a uniformly distributed rotating roller rotatably connected to the front side of the mounting base, and a protective mechanism sleeved on the front side of the mounting base and outside the rotating rollers.
[0007] The protective mechanism includes a protective cover fitted on the front side of the mounting base and located outside the rotating roller. A first through cavity is opened on the front side of the protective cover, and a second through cavity is opened on both sides of the protective cover and on both sides of the bottom rotating roller.
[0008] As a preferred embodiment of this utility model, a first storage groove is provided on both sides of the top of the mounting base, and a mounting rod is slidably connected inside the first storage groove. The front side of the mounting rod is fixedly connected to the rear side of the protective cover.
[0009] As a preferred embodiment of this utility model, two electric push rods are fixedly installed on the rear side of the mounting base, and the output shaft of the electric push rod passes through the interior of the first storage groove and is fixedly connected to the rear side of the mounting rod.
[0010] As a preferred embodiment of this utility model, the bottom of the mounting base has two second storage slots, and two lifting adjustment rods are interlaced inside the second storage slots. The bottom of the lifting adjustment rods is fixedly connected to the top of the mounting plate.
[0011] As a preferred embodiment of this utility model, the mounting base has limit grooves on both sides of the second storage groove, and a limit rod is slidably connected inside the limit groove. One side of the limit rod is fixedly connected to the lifting adjustment rod.
[0012] As a preferred embodiment of this utility model, two hydraulic rods are fixedly installed on the top of the mounting base, and the output shaft of the hydraulic rods passes through the interior of the second storage groove and is fixedly connected to the top of the lifting adjustment rod.
[0013] In a preferred embodiment of this utility model, a drive motor is fixedly installed on the rear side of the mounting base, the output shaft of the drive motor passes through the interior of the mounting base and is connected to the input shaft of the reducer inside the mounting base, and the rear side of the rotating roller passes through the interior of the mounting base and is connected to the output shaft of the reducer.
[0014] This utility model has the following beneficial effects:
[0015] 1. Prevent fiber breakage and loss: The protective cover in the protective mechanism can be completely fitted on the outside of the rotating roller, which can effectively isolate the rotating roller from contact with external personnel or debris; at the same time, when the fiber is drawn on the rotating roller, the protective cover can prevent it from breaking due to accidental contact, reduce raw material loss during processing, ensure the continuity of the fiber drawing process, reduce the production rework rate caused by fiber breakage, and improve production efficiency.
[0016] 2. Improve production operation safety: The rotating roller is in a high-speed rotation state during operation. The protective cover can form a physical isolation barrier to prevent operators from accidentally touching the rotating roller and causing safety accidents, thus providing safety assurance for workshop production. In addition, the first cavity on the front side of the protective cover can be used to observe the running status of the rotating roller and the fiber stretching in real time. The processing progress can be grasped without disassembling the protective cover, which takes into account both protection and operation convenience. Attached Figure Description

[0027] Example
[0028] The mechanical compact spinning gathering and drawing mechanism provided in this embodiment, such as Figures 1-5 As shown, the device includes a mounting base 1, a mounting plate 5 at the bottom of the mounting base 1, two support rods 6 fixedly mounted at the bottom of the mounting plate 5, and a uniformly distributed rotating roller 2 rotatably connected to the front side of the mounting base 1. A protective mechanism 3 is sleeved on the front side of the mounting base 1 and outside the rotating roller 2. The rotating roller 2 is used to stretch the fiber filaments, and the mounting plate 5 is used to support the mounting base 1, thereby facilitating the overall installation. The protective mechanism 3 is used to protect the outside of the rotating roller 2 to prevent the rotating roller 2 from being touched during actual use, which could cause the fiber filaments to break and affect processing.
[0029] The protective mechanism 3 includes a protective cover 304 fitted on the front side of the mounting base 1 and located outside the rotating roller 2. A first through cavity 302 is provided on the front side of the protective cover 304, and a second through cavity 305 is provided on both sides of the protective cover 304 and on both sides of the bottom rotating roller 2. The protective cover 304 is used to fit on the outside of the rotating roller 2 for protection. The second through cavity 305 is used to allow the fiber filaments to enter and exit. The first through cavity 302 is used to allow observation of the rotating roller 2 and the fiber filaments.
[0030] The top of the mounting base 1 has two first storage slots 301 on both sides. The first storage slot 301 is slidably connected to the inside of the first storage slot 303. The front side of the mounting rod 303 is fixedly connected to the rear side of the protective cover 304. The first storage slot 301 and the mounting rod 303 are provided to install the protective cover 304 and to adjust the protective cover 304.
[0031] Two electric push rods 306 are fixedly installed on the rear side of the mounting base 1. The output shaft of the electric push rod 306 passes through the interior of the first receiving groove 301 and is fixedly connected to the rear side of the mounting rod 303. The electric push rod 306 is used to drive the mounting rod 303, thereby moving the protective cover 304, so that the protective cover 304 moves out from the outside of the rotating roller 2 and the fiber filament passes through the interior of the rotating roller 2, which is convenient for subsequent stretching.
[0032] The bottom of the mounting base 1 has two second storage slots 11, and two lifting adjustment rods 8 are interspersed inside the second storage slots 11. The bottom of the lifting adjustment rods 8 is fixedly connected to the top of the mounting plate 5. The second storage slots 11 are designed to accommodate the lifting adjustment rods 8.
[0033] Limiting grooves 10 are provided inside the mounting base 1 and on both sides of the second storage slot 11. A limiting rod 9 is slidably connected inside the limiting groove 10. One side of the limiting rod 9 is fixedly connected to the lifting adjustment rod 8. The limiting rod 9 and the limiting groove 10 are used to stabilize the lifting adjustment rod 8 as it passes through the second storage slot 11, thereby increasing the overall stability during connection.
[0034] Two hydraulic rods 4 are fixedly installed on the top of the mounting base 1. The output shaft of the hydraulic rod 4 passes through the interior of the second storage groove 11 and is fixedly connected to the top of the lifting adjustment rod 8. The hydraulic rods 4 are used to push the mounting base 1 to rise and fall relative to the lifting adjustment rod 8, thereby adjusting the position of the mounting base 1 to meet different height requirements in production.
[0035] A drive motor 7 is fixedly installed on the rear side of the mounting base 1. The output shaft of the drive motor 7 passes through the interior of the mounting base 1 and is connected to the input shaft of the reducer inside the mounting base 1. The rear side of the rotating roller 2 passes through the interior of the mounting base 1 and is connected to the output shaft of the reducer. The drive motor 7 drives the rotating roller 2 to rotate under the action of the reduction mechanism to achieve the stretching of the fiber filament. The reduction mechanism is an existing mechanism and therefore is not specifically shown in this utility model.
[0036] Working principle:
[0037] Fixed support: The mounting plate 5 is fixed to the workshop floor or production frame by two support rods 6 at the bottom, forming a stable basic support structure; the lifting adjustment rod 8 at the bottom of the mounting base 1 is inserted into the second storage slot 11. In the initial state, the cooperation between the lifting adjustment rod 8 and the second storage slot 11 can initially position the mounting base 1 and prevent it from shifting in subsequent operations.
[0038] Components are ready: the drive motor 7, electric push rod 306, and hydraulic rod 4 are all in a power-off standby state; the protective cover 304 is initially fitted on the outside of the rotating roller 2, and the surface condition of the rotating roller 2 can be observed through the first cavity 302 to ensure that there are no foreign objects left, thus preparing for the subsequent fiber drawing.
[0039] The protective cover is opened: the electric push rod 306 is activated, and its output shaft extends forward, pushing the mounting rod 303 in the first storage groove 301 to slide along the groove. Since the front side of the mounting rod 303 is fixedly connected to the protective cover 304, the protective cover 304 moves forward synchronously with the mounting rod 303, gradually moving out from the outside of the rotating roller 2 until the rotating roller 2 is completely exposed, making room for the fiber threading.
[0040] Fiber path layout: The operator introduces one end of the fiber to be drawn from the second cavity 305 on one side of the protective cover 304, and then passes it around the surface of multiple rotating rollers 2 on the front side of the mounting base 1 in sequence. Finally, the other end of the fiber is led out from the second cavity 305 on the other side of the protective cover 304, completing the initial layout of the fiber.
[0041] Protective cover reset protection: After the fiber filaments are laid out, the electric push rod 306 is started in reverse. The output shaft retracts and drives the mounting rod 303 and the protective cover 304 to move backward until the protective cover 304 is re-covered on the outside of the rotating roller 2, restoring the protective state. At this time, the fiber filaments remain continuous through the second passage 305 on both sides, without affecting the subsequent stretching movement.
[0042] Based on the height of the preceding and following production equipment, activate the two hydraulic rods 4 on the top of mounting base 1:
[0043] Height increase: If it is necessary to raise the height of the rotating roller 2 to match the subsequent equipment, the output shaft of the hydraulic rod 4 extends upward. Since the output shaft of the hydraulic rod 4 is fixedly connected to the top of the lifting adjustment rod 8, the hydraulic rod 4 will drive the mounting seat 1 to move upward along the lifting adjustment rod 8. The second storage slot 11 rises synchronously with the mounting seat 1, and the insertion length of the lifting adjustment rod 8 in the slot is shortened.
[0044] Height reduction: If it is necessary to reduce the height, the output shaft of the hydraulic rod 4 retracts downward, pulling the mounting base 1 down along the lifting adjustment rod 8, and increasing the insertion length of the lifting adjustment rod 8 in the second storage slot 11.
[0045] Stable limiting: During the adjustment process, the limiting rods 9 on both sides of the lifting adjustment rod 8 always slide within the limiting groove 10, limiting the lifting adjustment rod 8 to move only in the vertical direction, preventing the mounting seat 1 from tilting, ensuring that the rotating roller 2 remains horizontal after the height is adjusted, and preventing the fiber filaments from being subjected to uneven force due to the tilt of the roller body.
[0046] Power drive and speed regulation: Start the drive motor 7 on the rear side of the mounting base 1. Its output shaft passes through the inside of the mounting base 1 and is connected to the preset reducer input shaft. According to the fiber material, thickness and drawing process requirements, the reduction mechanism adjusts the output speed and transmits the power to each rotating roller 2, driving the rotating roller 2 to rotate synchronously at the preset speed.
[0047] Aggregation and stretching operation: When the rotating roller 2 rotates, the friction between its surface and the fiber filament drives the fiber filament to move along the direction of "inlet → rotating roller group → outlet"; since the rotating roller 2 is arranged at a preset interval, the fiber filament is gradually stretched during the winding process, achieving the "stretching" effect; at the same time, the arrangement density and surface roughness of the rotating roller 2 are optimized, which can keep the fiber filament in an "aggregated" state during stretching, ensuring that the fiber filament is uniform in thickness and has a compact structure after stretching.
[0048] Real-time status monitoring: Operators can observe the rotation status of the rotating roller 2 and the fiber stretching status in real time through the first passage 302 on the front side of the protective cover 304. If any abnormality is found, the machine can be stopped and adjusted in time to ensure the stretching quality.
[0049] During the continuous stretching operation:
[0050] The protective function remains effective: the protective cover 304 always isolates the external contact, preventing personnel from accidentally touching the high-speed rotating roller 2, while also preventing debris from falling between the rotating roller 2 and the fiber filaments, reducing the risk of filament breakage.
[0051] Stable power and adjustment: The drive motor 7 maintains the rotation speed of the rotating roller 2 through the reduction mechanism, the hydraulic rod 4 keeps the height of the mounting base 1 fixed, and the limiting structure ensures overall stability until the fiber filaments of this batch are drawn. After the equipment stops, the above process can be repeated for the next batch of work.
[0052] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
