Description

Technical Field

[0001] This utility model belongs to the field of aluminum-plastic composite belt production technology, and specifically relates to an aluminum-plastic composite belt correction device. Background Technology

[0002] A web-correcting device is a mechanical device that corrects lateral errors that occur when components such as roll materials move forward on the production line. Aluminum-plastic composite belts have a smooth surface. When passing through the horn diaphragm, the aluminum-plastic composite belt is prone to deviation due to structural changes and uneven tension, which ultimately leads to uneven longitudinal wrapping and affects product quality. Therefore, it is very important to design a web-correcting mechanism before the aluminum-plastic composite belt enters the horn diaphragm.

[0003] A search revealed a Chinese utility model patent for "An Aluminum-Plastic Composite Belt Correction Auxiliary Device," with publication number CN216426251U. This utility model, an aluminum-plastic composite belt correction auxiliary device, primarily uses a positioning frame and pressure sensors to detect whether the aluminum-plastic composite belt deviates from its designated position on the production line. The pressure sensor relays the belt's position to an electronic control device, which then controls the correction mechanism and the rotation of a lead screw to return the clamping rollers to the correct position. Existing technology corrects the aluminum-plastic composite belt by translating it while clamping it, resulting in a complex structure and poor practicality. Furthermore, the pressure sensor is susceptible to environmental factors such as temperature and humidity, and its measurement accuracy may decrease after prolonged use. Summary of the Invention

[0004] The purpose of this invention is to provide an aluminum-plastic composite belt correction device to solve the problem of deviation of aluminum-plastic composite belts during transportation in the prior art, and to improve the accuracy and quality of longitudinal wrapping of aluminum-plastic composite belts.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An aluminum-plastic composite belt correction device includes a base, a bracket, and a correction actuator;

[0007] The base is provided with a linear slide rail, and the bottom of the bracket cooperates with the linear slide rail. The bracket is used to install the aluminum-plastic composite strip roll, so that the aluminum-plastic composite strip is laid between the fixed wheel and the pressure wheel.

[0008] The correction actuator includes a detector, a controller, and an actuator. The actuator includes a linear motor and a connecting rod. The detector is located between the fixed wheel and the pressure wheel, at the edge of the aluminum-plastic composite belt. The signal output terminal of the detector is connected to the signal input terminal of the controller. The signal output terminal of the controller is connected to the signal input terminal of the linear motor. The linear motor is fixed on the base. The output shaft of the linear motor is fixed with a connecting rod. The other end of the connecting rod is connected to the bracket.

[0009] Furthermore, one end of the connecting rod is keyed to the output shaft of the linear motor, and the other end is provided with an annular buckle. The bracket is provided with an annular groove, and the annular buckle is axially positioned and connected to the annular groove.

[0010] Furthermore, the guiding direction of the linear slide rail is parallel to the axial direction of the connecting rod.

[0011] Furthermore, the detector is an ultrasonic sensor.

[0012] Furthermore, the ultrasonic sensor includes two parallel sensing heads, with the edge of the aluminum-plastic composite strip positioned between the two sensing heads, and the distance from the aluminum-plastic composite strip to the two sensing heads being equal.

[0013] Compared with existing technologies, this utility model provides an aluminum-plastic composite tape correction auxiliary device. A detection mechanism monitors the deviation of the aluminum-plastic composite tape on the production line and transmits the tape's position to a controller in real time. The controller performs dynamic compensation calculations in real time, and the actuator slides along a linear guide rail via a push-pull bracket to correct the misaligned aluminum tape in the opposite direction. This avoids substandard longitudinal wrapping caused by tape misalignment. This application effectively improves longitudinal wrapping quality and ensures the reliability of finished aluminum-plastic composite tape products in applications such as communication cables.

[0016] The present invention will be further described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The terms such as "upper," "lower," "left," and "right" used in this specification are only for clarity of description and are not intended to limit the scope of implementation of the present invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of the present invention.

[0017] like Figure 1As shown, an aluminum-plastic composite tape correction device includes a base 1, a bracket 8, and a correction actuator. The base 1 is equipped with a linear slide rail. To ensure smooth movement of the bracket 8 on the base 1, a double-rail structure is preferably adopted. The guiding direction of the linear slide rail is parallel to the axial direction of the connecting rod 7 described below. The bottom of the bracket 8 cooperates with the linear slide rail. The bracket 8 is used to mount the aluminum-plastic composite tape roll 13. The aluminum-plastic composite tape 12 extending from the roll 13 is laid between the fixed wheel 4 and the pressure wheel 5 in the production line.

[0018] The correction actuator includes a detector, a controller 3, and an actuator. Since the aluminum-plastic composite belt is prone to deviation when passing the horn diaphragm due to structural abrupt changes and uneven tension, and the horn diaphragm is located at the front end of the fixed wheel, to get as close to the horn diaphragm as possible, this application places the detector between the fixed wheel 4 and the pressure wheel 5, at the edge of the aluminum-plastic composite belt 12. The detector commonly uses an ultrasonic sensor 2 or a photoelectric sensor; in this embodiment, an ultrasonic sensor 2 is used. The ultrasonic sensor 2 includes two parallel sensing heads, forming a detection area between them. The edge of the aluminum-plastic composite belt 12 is positioned between the two sensing heads, and the distance from the aluminum-plastic composite belt 12 to the two sensing heads is equal. The ultrasonic sensor 2 has a response time of 1ms and a detection accuracy of 0.1mm, enabling rapid and accurate detection of the deviation of the aluminum-plastic composite belt 12. The detection result is converted into an electrical signal and transmitted to the controller 3 in real time. The controller 3 acquires the deviation signal of the aluminum-plastic composite belt 12 and drives the actuator to perform the correction operation.

[0019] The actuator includes a linear motor 6 and a connecting rod 7. The tail of the linear motor 6 is equipped with a spherical bearing seat 9, which is fixed to the base 1. The output shaft of the linear motor 6 is fixedly connected to one end of the connecting rod 7, and the other end of the connecting rod 7 is connected to a bracket 8. The connection can be made by welding, bonding, or other methods. This embodiment further provides a preferred method: the end of the connecting rod 7 pointing towards the bracket 8 is provided with an annular buckle 10, and the side of the bracket 8 facing the connecting rod 7 is welded with an annular groove 11. The annular buckle 10 and the annular groove are axially positioned together. When the aluminum-plastic composite belt deviates at the diaphragm, the ultrasonic sensor detects the deviation angle. The controller 3 controls the actuator to perform a correction operation. The linear motor 6 pushes the connecting rod 7 in the opposite direction to the deviation of the aluminum-plastic composite belt, thereby pushing the bracket 8 to move on the linear slide rail of the base 1. Through reverse correction, the aluminum-plastic composite belt returns to the correct position, completing the correction operation for the aluminum-plastic composite belt 12.

[0020] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included within the protection scope of the present utility model patent application.
