Dual-station winding embedded internal pressure roller mechanism

Abstract

This utility model discloses a dual-station winding embedded internal pressure roller mechanism. The internal pressure roller mechanism includes a rodless cylinder, a mounting arm, a drive motor, and a pressure roller. The mounting arm is mounted on the rodless cylinder, and the drive motor and the rotatable pressure roller are fixedly mounted on the mounting arm. The rodless cylinder is positioned corresponding to the first and second winding shafts, and upon startup, it drives the mounting arm to move towards the first or second winding shaft, causing the pressure roller to press against the material on the first or second winding shaft. The drive motor connects to the pressure roller, thus driving the pressure roller to rotate actively upon startup. This utility model pre-drives the pressure roller with the drive motor, synchronizing the pressure roller with the winding speed before pressing, eliminating surface abrasion caused by speed differences. After stable pressing, the power to the pressure roller is removed, eliminating vibration between the pressure roller and the drive motor structure, which is more conducive to obtaining ideal crushing and winding effects, and also achieves energy saving.

Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, and more specifically to a dual-station winding embedded internal pressure roller mechanism. Background Technology

[0002] In the coating industry, during high-speed center winding of materials, airflow is drawn into the material layers, forming air bubbles that affect smoothness and light transmittance. During dual-station roll changeovers, sudden tension changes cause misalignment of the entire roll surface, resulting in poor winding and a decrease in finished product yield. To address these issues, internal pressure roller mechanisms are widely used in the center winding process of the coating industry.

[0003] Traditionally, the internal pressure roller is a passive roller. After winding and changing rolls, the speed of the internal pressure roller before applying pressure is 0, while the winding drum rotates at high speed based on the rated linear speed of the unit. At the moment of collision between the internal pressure roller and the drum, the speed difference can cause scratches and abrasions on the surface of the winding drum. After the internal pressure roller is rubbed by the drum to achieve speed synchronization, the speed difference disappears. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a dual-station winding embedded inner pressure roller mechanism. By adding power to the pressure roller and pre-driving it before pressing, the impact of pressure roller bounce on the winding surface quality is reduced, thereby ensuring the quality of material winding.

[0005] This utility model provides the following technical solution: a dual-station winding embedded inner pressure roller mechanism, including a first winding shaft and a second winding shaft arranged at intervals. The material is conveyed to the first winding shaft or the second winding shaft for winding through the winding mechanism. An inner pressure roller mechanism is arranged between the first winding shaft and the second winding shaft. The inner pressure roller mechanism is movably pressed onto the material on the first winding shaft or the second winding shaft for synchronous rotation. The inner pressure roller mechanism includes a rodless cylinder, a mounting arm, a drive motor, and a pressure roller. The mounting arm is arranged on the rodless cylinder. The drive motor and the pressure roller are respectively fixed on the mounting arm. The rodless cylinder is positioned corresponding to the first winding shaft and the second winding shaft, so that when started, it drives the mounting arm to move towards the first winding shaft or the second winding shaft, so that the pressure roller presses onto the material on the first winding shaft or the second winding shaft. The drive motor is connected to the pressure roller, so that when started, it drives the pressure roller to rotate actively.

[0006] As an improvement, the pressure roller includes a mandrel and an outer roller. The outer roller is rotatably mounted on the mandrel, which is rotatably mounted on the mounting arm and connected to a drive motor. The outer roller contacts and engages with the material on the first or second take-up shaft.

[0007] As an improvement, bearings are provided at both ends of the outer roller, and the bearings cooperate with the mandrel to allow the outer roller to rotate relative to the mandrel; retaining rings are provided on the outer side of the bearings at both ends, and the retaining rings are installed on the mandrel to limit the axial position of the outer roller.

[0008] As an improvement, the inner pressure roller mechanism also includes a guide rail arranged parallel to the rodless cylinder, and the mounting arm is slidably mounted on the guide rail.

[0009] As an improvement, the rodless cylinder and guide rail are symmetrically arranged on both sides of the pressure roller, thereby synchronously driving the mounting arms on both sides to move horizontally.

[0010] As an improvement, a pressure roller pulley is provided on the outside of the mounting arm, and a motor pulley is provided on the outside of the mounting arm for the drive motor. A synchronous belt is wound around the pressure roller pulley and the motor pulley for linkage.

[0011] As an improvement, a tensioning wheel is also provided on the mounting arm, which contacts the timing belt from the outside inward to tension it.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting a drive motor to pre-drive the pressure roller, the speed of the pressure roller is synchronized with the winding speed before pressing, eliminating scratches on the roll surface caused by speed difference, thereby ensuring the product quality after the material is wound.

[0014] 2. After the pressing is stable, the power to the pressure roller is removed to eliminate the vibration between the pressure roller and the drive motor structure, which is more conducive to obtaining the ideal rolling and winding effect, and also achieves the effect of energy saving.

[0019] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 ,2 Figures 3 and 4 show specific embodiments of the dual-station winding embedded inner pressure roller mechanism of this utility model. This embodiment includes a first take-up shaft 1 and a second take-up shaft 2 spaced apart. Material is conveyed to the first take-up shaft 1 or the second take-up shaft 2 by a take-up mechanism 3 for take-up. An inner pressure roller mechanism 4 is provided between the first take-up shaft 1 and the second take-up shaft 2. The inner pressure roller mechanism 4 presses against the material on the first take-up shaft 1 or the second take-up shaft 2 and rotates synchronously. The inner pressure roller mechanism 4 includes a rodless cylinder 41, a mounting arm 42, a drive motor 43, and a pressure roller 44. The mounting arm 42 is provided on the rodless cylinder 41. The drive motor 43 and the pressure roller 44 are fixedly provided on the mounting arm 42 respectively. The rodless cylinder 41 is positioned corresponding to the first take-up shaft 1 and the second take-up shaft 2. When started, it drives the mounting arm 42 to move towards the first take-up shaft 1 or the second take-up shaft 2, so that the pressure roller 44 presses against the material on the first take-up shaft 1 or the second take-up shaft 2. The drive motor 43 is connected to the pressure roller 44 and drives the pressure roller 44 to rotate actively when started.

[0021] In use, this utility model embeds the inner pressure roller mechanism 4 between two winding stations, i.e., the first winding shaft 1 and the second winding shaft 2 correspond to the two winding stations. Power and material are supplied by the existing winding mechanism 3 to the first winding shaft 1 or the second winding shaft 2, thereby performing the winding process at the first winding shaft 1 or the second winding shaft 2. After winding is completed at one winding station, the material can be transferred to another winding station by a worker, and then the inner pressure roller mechanism 4 is adjusted to the other winding station for winding, thus ensuring winding efficiency. Figure 1For example, the material is first wound up at the first take-up shaft 1. The specific pressure roller 44 in the inner pressure roller mechanism 4 reaches the first stop position A1 to press the material and cooperate with the winding. As the material is wound up larger and larger, the pressure roller 44 gradually moves to the stop position A2. After the winding of the predetermined diameter is completed, the first take-up shaft 1 stops running. The staff connects the material to the second take-up shaft 2 for winding. The pressure roller 44 moves to the second stop position B to press the material and cooperate with the winding. The above describes the principle of dual-station switching winding in the prior art. As a technical improvement of this invention, based on the translational adjustment of the pressure roller 44, a drive motor 43 is added. Before the pressure roller 44 presses against the first winding shaft 1 or the second winding shaft 2 to contact the material, the drive motor 43 is first started to drive the pressure roller 44 to the same rotational speed as the first winding shaft 1 or the second winding shaft 2. Then, the rodless cylinder 41 is activated to move the pressure roller 44 onto the material pressed against the first winding shaft 1 or the second winding shaft 2. This specific operation eliminates the surface abrasion caused by the original speed difference, thereby avoiding material damage and ensuring the product quality after winding. Furthermore, after the pressing is stable, the drive motor 43 can be stopped, thus removing the power to the pressure roller 44. This eliminates vibration between the transmission structure of the pressure roller 44 and the drive motor 43, which is more conducive to obtaining ideal crushing and winding effects, and also achieves energy saving.

[0022] As an improved specific embodiment, the pressure roller 44 includes a mandrel 441 and an outer roller 442. The outer roller 442 is rotatably sleeved on the mandrel 441. The mandrel 441 is rotatably mounted on the mounting arm 42 and connected to the drive motor 43. The outer roller 442 makes contact with the material on the first take-up shaft 1 or the second take-up shaft 2.

[0023] like Figure 2 , 3 As shown in Figure 4, the outer roller 442 is sleeved on the mandrel 441 and can rotate independently. When the drive motor 43 provides power, the mandrel 441 and the outer roller 442 can rotate synchronously to reach the required speed. After the outer roller 442 contacts the first take-up shaft 1 or the second take-up shaft 2, the speed of the outer roller 442 reaches synchronous stability with the first take-up shaft 1 or the second take-up shaft 2. After the drive motor 43 is stopped, the drive motor 43 and the mandrel 441 stop rotating, while the outer roller 442 rotates independently. This can eliminate the jump of the mandrel 441 and the vibration of the drive motor 43, ensuring the winding effect while reducing the wear on the drive motor 43, which is beneficial to improving the durability of the components and reducing maintenance costs.

[0024] As an improved specific implementation, bearings 443 are provided at both ends of the outer roller 442. The bearings 443 cooperate with the spindle 441 to allow the outer roller 442 to be rotatably set relative to the spindle 441. Retaining rings 444 are provided on the outer side of the bearings 443 at both ends. The retaining rings 444 are installed on the spindle 441 to limit the axial position of the outer roller 442.

[0025] like Figure 4 As shown, the outer roller 442 cooperates with the mandrel 441 through bearings 443 at both ends, reducing structural friction between the two and thus improving the smoothness of the outer roller 442 when rotating independently. The retaining ring 444 can be installed on the mandrel 441 by means of snap-fitting, fastener installation, etc., to limit the two ends of the outer roller 442, thereby achieving structural installation stability.

[0026] As an improved specific implementation, the inner pressure roller mechanism 4 also includes a guide rail 45 arranged parallel to the rodless cylinder 41, and the mounting arm 42 is slidably arranged on the guide rail 45.

[0027] like Figure 1 , 2 As shown, the guide rail 45, in conjunction with the rodless cylinder 41, allows the mounting arm 42 to slide more smoothly. In practice, the rodless cylinder 41 and the guide rail 45 are connected to the upper and lower positions of the mounting arm 42 respectively, ensuring the smooth movement of the mounting arm 42.

[0028] As an improved specific implementation, the rodless cylinder 41 and the guide rail 45 are symmetrically arranged on both sides of the pressure roller 44, thereby synchronously driving the mounting arms 42 on both sides to move horizontally.

[0029] like Figure 2 As shown, two sets of rodless cylinders 41 on both sides provide power for the translation of the mounting arm 42, ensuring the stability of the translational adjustment position of the mounting arm 42 and the pressure roller 44. Guide rails 45 are correspondingly set on both sides to provide sliding stability and structural stability.

[0030] As an improved specific implementation, the pressure roller 44 is provided with a pressure roller pulley 431 on the outside of the mounting arm 42, and the drive motor 43 is provided with a motor pulley 432 on the outside of the mounting arm 42. A synchronous belt 433 is wound around the pressure roller pulley 431 and the motor pulley 432 for linkage.

[0031] like Figure 3 As shown, the pressure roller pulley 431 and motor pulley 432 are set in the space outside the mounting arm 42, and then the synchronous belt 433 is wound around to realize the power transmission of the drive motor 43 to the pressure roller 44. It makes reasonable use of space for structural arrangement and realizes stable transmission.

[0032] As an improved specific implementation, the mounting arm 42 is also provided with a tensioning wheel 434, which abuts against the timing belt 433 from the outside to the inside to tension the timing belt 433.

[0033] like Figure 3 As shown, the tensioning wheel 434 contacts the synchronous belt 433 to tension it, thereby ensuring the stable transmission of the drive motor 43 to the pressure roller 44. In specific implementation, the tensioning wheel 434 can be set on the mounting arm 42 through a translation structure, so that the operator can adjust the tension.

[0034] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
