Description
Technical Field
[0001] This utility model relates to the field of material conveying and processing equipment technology, and in particular to a linear double-section material pulling mechanism. Background Technology
[0002] In modern industrial production, especially in the fields of electronics, batteries, printing, or packaging, it is often necessary to process long-length materials such as films, separators, or foils in roll-to-roll fashion. The material pulling mechanism is a key piece of equipment in this process, responsible for accurately pulling the material from the unwinding end to a preset length and conveying it to subsequent cutting, inspection, or lamination stations.
[0003] To ensure the length accuracy and repeatability of the material pulling, linear pulling mechanisms are commonly used in existing technologies. These mechanisms typically rely on a pulling assembly (such as grippers or pressure rollers) that reciprocates along a linear guide rail to pull the material. During operation, when a section of material needs to be pulled, this pulling assembly must travel along the guide rail completely to complete one pulling action.
[0004] However, this traditional linear material pulling method is showing increasingly prominent structural flaws when dealing with the growing demand for processing long materials. When the preset material pulling length is very large, the total stroke of the linear guide rail and its drive system supporting the material pulling assembly must also reach or exceed this length. This directly results in the entire material pulling mechanism becoming very large in the length direction, with a lengthy structure, greatly increasing the equipment's footprint and manufacturing costs. This is a problem that urgently needs to be solved in the space-constrained layout of modern factories.
[0005] Therefore, this utility model proposes a linear double-segment feeding mechanism to overcome the shortcomings of the prior art. Utility Model Content
[0006] To overcome the above shortcomings, this utility model provides a linear double-segment material pulling mechanism, which aims to improve the problems of long material pulling stroke, resulting in large physical size of the equipment in the length direction, large footprint, and redundant structure in the existing technology.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: a linear double-segment material pulling mechanism, comprising a material pulling guide rail and a linear mechanism, wherein the linear mechanism is slidably mounted on the material pulling guide rail;
[0008] As well as the material pulling roller mechanism, the material pulling pre-pressing mechanism, and the material pulling post-pressing mechanism;
[0009] The material pulling roller mechanism is fixedly connected to the linear mechanism. The material pulling roller mechanism includes an outer fixing frame for the material pulling roller, a material pulling inlet roller, and a material pulling outlet roller. The material pulling inlet roller is rotatably connected to the outer fixing frame for the material pulling roller, and the material pulling outlet roller is rotatably connected to the outer fixing frame for the material pulling roller. The material pulling inlet roller and the material pulling outlet roller together define a U-shaped material path.
[0010] Furthermore, the pre-pull pressing mechanism is fixedly connected to the linear mechanism and located at the material inlet end of the pull inlet roller; the post-pull pressing mechanism is fixedly connected to the linear mechanism and located at the material outlet end of the pull outlet roller.
[0011] Preferably, it also includes a feeding correction mechanism, which is located upstream of the material in the pre-pull pressing mechanism;
[0012] Preferably, the feeding correction mechanism includes a feeding correction sensor and a feeding correction electric cylinder, wherein the feeding correction sensor is electrically connected to the feeding correction electric cylinder;
[0013] Preferably, it also includes a diaphragm shaft, which is located on the upstream side of the material in the feed correction mechanism;
[0014] Preferably, it also includes a free step mechanism after material pulling, which is located downstream of the material in the pressing mechanism after material pulling;
[0015] Preferably, the end of the free step mechanism after pulling the material is provided with a material receiving and cutting platform;
[0016] Preferably, it also includes a receiving and correction mechanism, which includes a receiving shaft located downstream of the material on the receiving and cutting platform;
[0017] Preferably, both the pre-pull pressing mechanism and the post-pull pressing mechanism use non-elastic pressing components to press the material from both the top and bottom sides.
[0018] This utility model has the following beneficial effects:
[0019] 1. This utility model, by setting up a linear mechanism and fixing the material pulling roller mechanism, the material pulling pre-pressing mechanism, and the material pulling post-pressing mechanism to the linear mechanism, makes the material distributed in a U-shaped double segment within the material pulling roller mechanism. The linear mechanism only needs to move half of the material pulling length to achieve the pulling of a complete length of material, which solves the problem of long material pulling stroke in the prior art, resulting in large equipment footprint and redundant structure. It achieves the effect of significantly shortening the equipment stroke, saving equipment installation space, and improving production efficiency.
[0020] 2. This utility model uses a linear mechanism in conjunction with a material pulling guide for driving, and sets up a pre-pulling pressing mechanism and a post-pulling pressing mechanism that move synchronously with the linear mechanism to dynamically press the material throughout the process. This solves the problems of slippage, low precision, and easy scratching of materials by relying on friction rollers for material pulling in the prior art, and achieves the effects of high material pulling precision, accurate repeatability, and stable material operation.
[0021] 3. This utility model solves the problems in the prior art where materials are easily pulled, stretched, or broken during high-speed start-up and shutdown, and where traditional rubber rollers easily cause material damage to pressure points, by setting up a free step mechanism after material pulling to form a buffer between the material pulling assembly and the receiving and cutting platform, and by using a non-elastic pressing component for both the pre-pulling and post-pulling pressing mechanisms. This achieves the effects of protecting materials, reducing damage risks, and improving product yield. Attached Figure Description

[0028] 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.
[0029] Reference Figures 1-4 The present invention provides an embodiment of a linear double-segment material pulling mechanism, including a material pulling guide rail 401 and a linear mechanism 8. The linear mechanism 8 is slidably mounted on the material pulling guide rail 401, and the material pulling guide rail 401 provides guidance for the reciprocating motion of the linear mechanism 8. The mechanism also includes a material pulling roller mechanism 3 fixedly connected to the linear mechanism 8, a material pulling front pressing mechanism 2 fixedly connected to the linear mechanism 8, and a material pulling rear pressing mechanism 4 fixedly connected to the linear mechanism 8.
[0030] Specifically, the material pulling roller mechanism 3 includes a material pulling roller outer fixing frame 301, a material pulling inlet roller 302, and a material pulling outlet roller 201; the material pulling roller outer fixing frame 301 is fixedly connected to the linear mechanism 8; the material pulling inlet roller 302 is rotatably connected to the material pulling roller outer fixing frame 301; the material pulling outlet roller 201 is rotatably connected to the material pulling roller outer fixing frame 301; the material pulling inlet roller 302 and the material pulling outlet roller 201 together define a U-shaped material path; the material pulling pre-pressing mechanism 2 is located at the material inlet end of the material pulling inlet roller 302; the material pulling post-pressing mechanism 4 is located at... At the material outlet end of the material pulling roller 201; the pre-pulling pressing mechanism 2, the material pulling roller mechanism 3, and the post-pulling pressing mechanism 4 together constitute a material pulling assembly that moves synchronously with the linear mechanism 8 along the material pulling guide rail 401; along the material's forward direction, on the upstream side of the material in the pre-pulling pressing mechanism 2, an infeed correction mechanism 1 is provided, which includes an infeed correction sensor 102 and an infeed correction electric cylinder 101, with the infeed correction sensor 102 electrically connected to the infeed correction electric cylinder 101; on the upstream side of the material in the infeed correction mechanism 1, a diaphragm shaft 7 is also provided;
[0031] Furthermore, it also includes a free step mechanism 5 located downstream of the material in the pulling and pressing mechanism 4. The free step mechanism 5 forms a free travel space for storing part of the material during high-speed pulling. At the downstream end of the material in the free step mechanism 5, a receiving and cutting platform 501 is provided. The receiving and cutting platform 501 is a flat worktable used to receive the pulled material and perform the cutting process. A receiving and correcting mechanism 6 is provided downstream of the material in the receiving and cutting platform 501. The receiving and correcting mechanism 6 includes a receiving shaft 601, which is rotatably set to wind up the material. In order to stably hold the material during the pulling process and avoid crushing, both the pre-pulling pressing mechanism 2 and the post-pulling pressing mechanism 4 use non-elastic pressing parts to press the material from the upper and lower sides.
[0032] It also includes a feeding correction mechanism 1, which is located upstream of the material in the pre-pull pressing mechanism 2. The feeding correction mechanism 1 includes a feeding correction sensor 102 and a feeding correction electric cylinder 101. The feeding correction sensor 102 is electrically connected to the feeding correction electric cylinder 101. The diaphragm shaft 7 is rotatably located upstream of the material in the feeding correction mechanism 1. It also includes a post-pull free step mechanism 5, located downstream of the material in the post-pull pressing mechanism 4. The post-pull free step mechanism 5 provides a free stroke for the material as a buffer. The downstream end of the material free step mechanism 5 is provided with a receiving and cutting platform 501, and further includes a receiving and correction mechanism 6. The receiving and correction mechanism 6 is located on the downstream side of the material of the receiving and cutting platform 501, and includes a receiving shaft 601. Both the pre-pulling pressing mechanism 2 and the post-pulling pressing mechanism 4 use non-elastic pressing parts to press the material from the upper and lower sides. The specific structure of the non-elastic pressing part can be a hard roller or a smooth pressing block. This structure ensures stable holding force and avoids material damage caused by uneven elasticity of traditional rubber rollers.
[0033] Working principle: The material is released from the diaphragm shaft 7 and first passes through the feeding correction mechanism 1. The feeding correction sensor 102 of the feeding correction mechanism 1 detects the edge position of the material in real time. When the deviation is detected, the feeding correction sensor 102 electrically drives the feeding correction electric cylinder 101 to adjust the lateral position of the material and ensure that the material enters the subsequent feeding assembly in a straight line.
[0034] The material then enters the feeding assembly, which consists of a pre-feeding pressing mechanism 2, a feeding roller mechanism 3, and a post-feeding pressing mechanism 4. The pre-feeding pressing mechanism 2 and the post-feeding pressing mechanism 4 are activated first to stably press the material from the top and bottom sides. This pressing mechanism is preferably a non-elastic pressing component to avoid the risk of crushing. The material enters the feeding roller mechanism 3 under the pressed state, is guided through the feeding inlet roller 302, and is discharged around the feeding outlet roller 201. It is distributed in a U-shape between the two rollers supported by the feeding roller outer fixing frame 301.
[0035] When the material pulling action is performed, a power source (not shown) drives the linear mechanism 8. The linear mechanism 8 is slidably mounted along the material pulling guide rail 401 and begins to move smoothly in a straight line. Since the pre-pulling pressing mechanism 2, the material pulling roller mechanism 3, and the post-pulling pressing mechanism 4 are all fixedly connected to the linear mechanism 8, the movement of the linear mechanism 8 will drive the entire material pulling assembly to move synchronously. Based on the structure of the U-shaped material path, when the linear mechanism 8 drives the material pulling assembly to move half of the preset material pulling length, the inlet and outlet ends of the U-shaped path of the material are simultaneously pulled by half of the stroke. The superposition of the two makes the total material pulling length reach a complete preset length. This design halves the movement stroke of the linear mechanism 8, greatly shortens the equipment length, saves installation space, and at the same time, the linear mechanism 8, in conjunction with the linear movement of the material pulling guide rail 401, ensures high precision and high stability in material pulling.
[0036] During the material pulling process, the free step mechanism 5 after pulling is located downstream of the pressing mechanism 4 after pulling, providing a free buffer area for the material to prevent the material from being pulled and tightened instantly during high-speed start-stop. The material after pulling is conveyed to the receiving and cutting platform 501, where the receiving and cutting process is performed. The cut material finally enters the receiving and correction mechanism 6, which corrects the material again to ensure neat winding, and the material is finally wound up by the receiving shaft 601.
