Description

Technical Field

[0001] This utility model belongs to the field of winding technology, and specifically relates to a composite material winding mechanism. Background Technology

[0002] The main drawbacks of existing composite material winding mechanisms are uneven winding and material deformation. These shortcomings are usually related to the design of the winding mechanism. Specifically, uneven winding is mainly due to improper tension control during the winding process, resulting in localized slack or excessive tightness of the material during winding, thus affecting the final quality of the roll. Material deformation often stems from excessive stress or uneven force distribution on the composite material during winding, especially at higher winding speeds.

[0003] Conventional solutions to these problems include improving the tension control system to ensure uniform winding, adjusting the winding speed to reduce the risk of material deformation, and regularly maintaining and overhauling the equipment. However, these methods have drawbacks. Improving the tension control system often requires complex modifications to the equipment, increasing costs and time. Furthermore, while adjusting the winding speed can improve material stability, it may lead to reduced production efficiency and impact overall production schedules. Therefore, we aim to design a winding mechanism with a novel structure to address this issue. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a composite material winding mechanism to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a composite material winding mechanism, comprising: a winding assembly, wherein a pressing assembly for pressing and tightening the composite material is installed on the lower front side of the winding assembly, and a clamping assembly for adjusting the tension of the composite material is installed on the upper front side of the winding assembly.

[0006] The pressing assembly includes a pressing roller for directly rolling and flattening the composite material. The pressing roller is rotatably mounted on the upper end of the mounting frame via a bearing seat. The pressing assembly includes a pressing roller for adjusting the pressure of the pressing roller. The left and right ends of the pressing roller are respectively fixedly connected to the lower end of the piston rod of an electric cylinder via a bearing seat.

[0007] In a preferred embodiment, the winding assembly includes a frame for mounting a placement frame, with a placement frame for receiving the winding roll fixed to the upper left front side and right front side of the frame, respectively.

[0008] In a preferred embodiment, the upper ends of the two placement frames are movably equipped with winding rollers for winding the composite material, and the rear side of the upper end of the frame is equipped with a traction member for pulling and guiding the composite material. In actual use, the traction member can not only pull the composite material to be wound, but also align, pre-flatten, and guide it, so that the composite material is flattened as much as possible before being wound, thereby helping to improve the uniformity of winding.

[0009] In a preferred embodiment, the pulling member includes a stand and a pulling rod assembly. The pulling rod assembly is rotatably mounted on the upper end of the stand. The pulling rod assembly includes an upper roller and a lower roller, and the height of the lower roller is greater than the height of the take-up roller.

[0010] In a preferred embodiment, the lower roller is placed below the upper roller, and the right end of the lower roller is connected to the transmission chain via a gear.

[0011] The transmission chain is connected to the output end of the drive motor installed on the right rear side of the frame, and the left end of the drive motor is connected to the reducer shaft.

[0012] In a preferred embodiment, the pressing assembly further includes a lifting seat, the upper end of which is fixedly connected to the lower end of the mounting frame. The lifting seat includes a housing and a servo motor, the servo motor is installed at the bottom of the housing, and a bearing mounting plate is installed inside the lower end of the housing.

[0013] In a preferred embodiment, the output shaft of the servo motor is connected to the lower end of the lead screw rotatably mounted on the bearing mounting plate via a coupling, and a lifting cylinder for lifting the mounting frame is slidably mounted on the upper end of the housing via the lead screw.

[0014] In a preferred embodiment, the clamping assembly further includes a gantry frame, with a cantilever welded to the upper left front side and right front side of the gantry frame, and an electric cylinder installed on the upper front side of each cantilever.

[0015] In a preferred embodiment, the length of the abutting roller is the same as the length of the pressure roller, and the lengths of the abutting roller and the pressure roller are matched with the length of the take-up roller. In actual use, multiple pressure sensors with equal spacing are embedded and fixed inside the outer wall of the abutting roller and the pressure roller, and the outer ends of the pressure sensors slightly protrude from the outer wall surface of the abutting roller and the pressure roller, with a maximum protrusion height of no more than 2mm. In this way, without affecting normal operation, the pressure generated on the abutting roller and the pressure roller during the winding of the composite material can be monitored, thereby facilitating the real-time adjustment of the distance between the abutting roller and the pressure roller and the take-up roller, thus avoiding uneven winding of the composite material due to excessive pressure.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are: 1. By setting the tension member, by installing the tension member on the rear side of the upper end of the winding assembly, the tension member can not only pull the composite material to be wound, but also align and pre-flatten and guide it, so that the composite material is flattened as much as possible before being wound, thereby helping to improve the uniformity of winding.

[0017] 2. By setting up a pressing component and a clamping component, when the composite material is being wound by the take-up roller, the clamping component located on the upper side of the frame presses down on the composite material that is about to come into contact with the take-up roller through the pressing roller on it, so that the composite material between the take-up roller and the traction roller group is tensioned, avoiding uneven tension in some areas that may cause defects in the winding. At the same time, the abutting roller on the upper side of the pressing component presses against the outer side of the composite material that has just been wound at the lower end of the take-up roller. The rolling abutting roller rolls and presses this part of the composite material, flattening and pressing it, thereby improving the compactness of the composite material after winding.

[0026] 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.

[0027] Please see Figures 1 to 4 The present invention provides a technical solution: a composite material winding mechanism, comprising: a winding assembly 100, a pressing assembly 200 for pressing and tightening the composite material is installed on the lower front side of the winding assembly 100, and a pressing assembly 300 for adjusting the tension of the composite material is installed on the upper front side of the winding assembly 100.

[0028] The pressing assembly 200 includes a pressing roller 230 for directly pressing and flattening the composite material. The pressing roller 230 is rotatably mounted on the upper end of the mounting frame 220 via a bearing seat 1. The pressing assembly 300 includes a pressing roller 330 for adjusting the pressure of the pressing roller 330. The left and right ends of the pressing roller 330 are respectively fixedly connected to the lower end of the piston rod of an electric cylinder 340 via a bearing seat 2.

[0029] Please see Figures 1 to 1 The winding assembly 100 includes a frame 110 for mounting a placement rack 130, and a placement rack 130 for receiving the winding roll 120 is fixed on the left front side and right front side of the upper end of the frame 110, respectively.

[0030] Two placement racks 130 have take-up rollers 120 for winding up the composite material movably placed on their upper ends. A tensioning member 140 for pulling and guiding the composite material is installed on the rear side of the upper end of the frame 110. In actual use, the tensioning member 140 can not only pull the composite material to be wound, but also align, pre-flatten, and guide it, so that the composite material is flattened as much as possible before being wound up, thereby helping to improve the uniformity of winding.

[0031] The traction component 140 includes a stand 142 and a traction roller assembly. The traction roller assembly is rotatably mounted on the upper end of the stand 142. The traction roller assembly includes an upper roller and a lower roller. The height of the lower roller is greater than the height of the take-up roller 120.

[0032] The lower roller is placed below the upper roller, and the right end of the lower roller is connected to the transmission chain 143 via a gear.

[0033] The transmission chain 143 is connected to the output end of the drive motor 144 installed on the right rear side of the frame 110, and the left end of the drive motor 144 is connected to the reducer shaft.

[0034] As the first embodiment of this utility model, by setting up the tension member 140, and by installing the tension member 140 on the upper rear side of the winding assembly 100, in actual use, the composite material first passes through the upper and lower rollers on the tension roller group, and then moves towards the winding roller 120 under the coordinated tension of the upper and lower rollers. During this process, the tension member 140 can not only pull the composite material to be wound, but also align, pre-flatten, and guide it, so that the composite material is flattened as much as possible before being wound, thereby helping to improve the uniformity of winding.

[0035] Please see Figures 1 to 4 The pressing component 200 also includes a lifting seat 210. The upper end of the lifting seat 210 is fixedly connected to the middle of the lower end of the mounting frame 220. The lifting seat 210 includes a housing 211 and a servo motor 215. The servo motor 215 is installed at the bottom of the housing 211, and a bearing mounting plate is installed inside the lower end of the housing 211.

[0036] The output shaft of the servo motor 215 is connected to the lower end of the lead screw 213, which is rotatably mounted on the bearing mounting plate, via a coupling. The upper end of the housing 211 is equipped with a lifting cylinder 214 for lifting the mounting frame 220 via the lead screw 213.

[0037] The clamping assembly 300 also includes a gantry frame 310, with a cantilever 320 welded to the upper left front side and right front side of the gantry frame 310 respectively, and an electric cylinder 340 is installed on the upper front side of each cantilever 320.

[0038] The length of the abutment roller 230 is the same as the length of the pressure roller 330, and the lengths of the abutment roller 230 and the pressure roller 330 are matched with the length of the take-up roller 120. In actual use, multiple pressure sensors with equal spacing are embedded and fixed inside the outer wall of the abutment roller 230 and the pressure roller 330. The outer end of the pressure sensor protrudes slightly from the outer wall surface of the abutment roller 230 and the pressure roller 330, with a maximum protrusion height of no more than 2mm. In this way, without affecting normal operation, the pressure generated on the abutment roller 230 and the pressure roller 330 during composite material winding can be monitored, thereby facilitating the real-time adjustment of the distance between the abutment roller 230 and the pressure roller 330 and the take-up roller 120, thus avoiding uneven winding of composite material due to excessive pressure.

[0039] As a second embodiment of this utility model, based on the first embodiment described above, by setting up a pressing component 200 and a clamping component 300, in actual use, when the composite material is being wound by the take-up roller 120, the clamping component 300 located on the upper side of the frame 110 uses the pressing roller 330 on it to press down the composite material that is about to contact the take-up roller 120 for winding, so that the composite material between the take-up roller 120 and the traction roller group is tensioned, avoiding uneven tension in some areas that could cause defects in winding. At the same time, the abutting roller 230 on the upper side of the pressing component 200 presses against the outer side of the composite material that has just been wound at the lower end of the take-up roller 120. The rolling abutting roller 230 rolls and presses this part of the composite material, flattening and pressing it, thereby improving the compactness of the composite material after winding. In addition, multiple equally spaced pressure rollers are embedded and fixed inside the outer wall of both the abutting roller 230 and the pressing roller 330. The pressure sensor, with its outer end slightly protruding from the outer wall surface of the abutment roller 230 and the pressure roller 330, can monitor the pressure exerted on the abutment roller 230 and the pressure roller 330 during composite material winding. This allows for real-time adjustment of the distance between the abutment roller 230 and the pressure roller 330 and the winding roller 120. For example, if the pressure exceeds the upper threshold, the lifting seat 210 lowers the mounting frame 220 and the electric cylinder 340 moves the abutment roller 230 upward. Conversely, if the pressure is below the lower threshold, the lifting seat 210 raises the mounting frame 220 and the electric cylinder 340 presses down the abutment roller 230. (The pressure sensor is connected to an external PLC controller, which controls the electric cylinder 340 and the lifting seat 210 based on real-time pressure feedback. This is existing technology, and its specific working principle and connection structure are not described here.) This prevents uneven winding of the composite material due to excessive pressure.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
