Description

Technical Field

[0001] This utility model belongs to the technical field of packaging bag processing equipment, and in particular relates to a horizontal double-shaft automatic winding machine for packaging bag processing. Background Technology

[0002] In the packaging bag processing flow, winding is a crucial step connecting printing, bag making, and other processes. The quality of winding directly affects the subsequent cutting and sealing accuracy of the packaging bag. Uneven winding tension can easily lead to wrinkles and uneven edges on the packaging bag; excessive tension can cause film stretching and deformation, affecting the dimensional stability of the finished product. Therefore, the tension control capability and heat dissipation reliability of the winding machine are core elements to ensure the quality of packaging bag processing.

[0003] In existing equipment, the basic control of the winding process is achieved by combining a tension sensor and a single motor drive. However, the tension control accuracy is low, it relies on an external tension sensor to collect data, and it is easily affected by dust and vibration on the surface of the packaging bag. Furthermore, the tension shaft driven by the single motor is prone to tilting due to uneven force, resulting in tension deviation on both sides. Therefore, we propose a horizontal dual-shaft automatic winding machine for packaging bag processing. Utility Model Content

[0004] The purpose of this invention is to provide a horizontal dual-shaft automatic winding machine for packaging bag processing, which solves the problem of low tension control accuracy of existing equipment through a dual-drive symmetrical tensioning system and power linkage control.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a horizontal double-shaft automatic winding machine for packaging bag processing, including: a winding machine body and a winding shaft one, the circumferential surface of the winding shaft one is rotatably connected to the winding machine body, the inner circumferential surface of the winding machine body is rotatably connected to the winding shaft two, and a tensioning device is provided inside the winding machine body.

[0007] The tensioning device includes a movable base, the bottom of which is fixedly connected to the inner wall side of the winding machine body. A threaded rod is rotatably connected inside the movable base. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rod. A tensioning shaft is rotatably connected to the side of the threaded sleeve. A drive motor is fixedly connected to the bottom end of the threaded rod. The circumferential surface of the drive motor is fixedly connected to the inner circumferential surface of the winding machine body. A controller is fixedly connected to the inner wall side of the winding machine body.

[0008] Furthermore, the controller is electrically connected to the drive motor, enabling the controller to accurately collect the power data of the drive motor and infer the current tension of the packaging bag through the power. At the same time, the controller can directly send adjustment commands to the drive motor to change the height of the tensioning shaft by controlling the rotation speed of the threaded rod, thereby achieving tension control.

[0009] Furthermore, there are two drive motors and two controllers, and they are symmetrical about each other along the vertical centerline of the tension shaft. The two symmetrical drive motors and controllers allow the controller to read and compare the power of the two motors respectively. The difference in power is used to determine whether the force on the tension shaft is balanced. If a deviation occurs, the speed of the corresponding motor is adjusted independently to ensure that the tension shaft always remains horizontal.

[0010] Furthermore, an anti-slip sleeve is fixedly connected to the circumferential surface of the tensioning shaft. The anti-slip sleeve can enhance the friction between the tensioning shaft and the packaging bag, ensuring that the tension adjustment force of the tensioning shaft can be stably transmitted to the packaging bag, avoiding deviation between the actual tension and the power-related tension inferred by the controller due to slippage, and ensuring the accuracy of tension control.

[0011] Furthermore, a cooling device is provided on the circumferential surface of the first drive motor. The cooling device includes a support frame, the side of which is fixedly connected to the side of the movable base. An impeller is rotatably connected to the inner circumferential surface of the support frame, and a second drive motor is fixedly connected to one end of the impeller.

[0012] Furthermore, the second drive motor is electrically connected to the controller, enabling the controller to dynamically adjust the heat dissipation intensity based on the power data of the first drive motor, thus avoiding the energy waste of traditional constant-speed heat dissipation.

[0013] Furthermore, the cooling device is provided in two parts, and they are symmetrical to each other along the vertical central axis of the tensioning shaft. The two symmetrical cooling devices are precisely matched with the layout of the dual drive motors, which can provide independent heat dissipation for each motor, ensuring that the heat dissipation effect is directly applied to the heat source.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model achieves precise closed-loop control of the packaging bag winding tension through the electrical linkage between the controller and the dual drive motor. The controller reads the operating power of the drive motor in real time and infers the tension. The tension shaft is driven to rise and fall synchronously by the dual symmetrical motors, and the anti-slip sleeve ensures stable tension transmission. This not only avoids the defects of traditional tension sensors being susceptible to interference, but also solves the problem of tension shaft tilting caused by single motor drive. It effectively reduces defects such as wrinkles and offsets during the packaging bag winding process, and improves the quality of finished products and winding accuracy.

[0016] 2. This utility model constructs an on-demand, graded heat dissipation system through the intelligent collaboration of the controller, the second drive motor, and the dual cooling device. The controller synchronously transmits the power data of the first drive motor to the second drive motor, dynamically adjusting the impeller speed. It achieves low-power heat dissipation and enhanced heat dissipation at high power. The dual symmetrical cooling device precisely matches the two motors to achieve directional heat dissipation, which avoids the energy waste of traditional constant-speed heat dissipation, ensures that the motor does not overheat under high load, extends the service life of the equipment, and meets the continuous operation requirements of mass production of packaging bags.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 This utility model is a horizontal double-shaft automatic winding machine for packaging bag processing, including: winding machine body 1 and winding shaft 1 2. The circumferential surface of winding shaft 1 2 is rotatably connected to winding machine body 1. The inner circumferential surface of winding machine body 1 is rotatably connected to winding shaft 2 3. A tensioning device 4 is provided inside winding machine body 1.

[0027] The tensioning device 4 includes a movable base 41, the bottom of which is fixedly connected to the inner wall side of the winding machine body 1. A threaded rod 42 is rotatably connected inside the movable base 41. A threaded sleeve 43 is threadedly connected to the circumferential surface of the threaded rod 42. A tensioning shaft 44 is rotatably connected to the side of the threaded sleeve 43. A drive motor 45 is fixedly connected to the bottom end of the threaded rod 42. The circumferential surface of the drive motor 45 is fixedly connected to the inner circumferential surface of the winding machine body 1. A controller 46 is fixedly connected to the inner wall side of the winding machine body 1.

[0028] As shown in the figure, the controller 46 is electrically connected to the drive motor 45. The electrical connection between the controller 46 and the drive motor 45 enables the controller 46 to accurately collect the power data of the drive motor 45 and infer the current tension of the packaging bag through the power. At the same time, the controller 46 can directly send adjustment commands to the drive motor 45 to change the height of the tensioning shaft 44 by controlling the rotation speed of the threaded rod 42, thereby realizing tension control.

[0029] As shown in the figure, there are two drive motors 45 and two controllers 46, which are symmetrical to each other along the vertical centerline of the tension shaft 44. The two symmetrical drive motors 45 and controllers 46 allow the controllers 46 to read and compare the power of the two motors respectively. The difference in power is used to determine whether the force on the tension shaft 44 is balanced. If there is a deviation, the speed of the corresponding motor is adjusted independently to ensure that the tension shaft 44 always remains horizontal.

[0030] As shown in the figure, an anti-slip sleeve 47 is fixedly connected to the circumferential surface of the tensioning shaft 44. The anti-slip sleeve 47 can enhance the friction between the tensioning shaft 44 and the packaging bag, ensuring that the tension adjustment force of the tensioning shaft 44 can be stably transmitted to the packaging bag, avoiding the deviation between the actual tension and the power-related tension inferred by the controller 46 due to slippage, and ensuring the accuracy of tension control.

[0031] As shown in the figure, a cooling device 5 is provided on the circumferential surface of the drive motor 45. The cooling device 5 includes a support frame 51. The side of the support frame 51 is fixedly connected to the side of the movable base 41. An impeller 52 is rotatably connected to the inner circumferential surface of the support frame 51. One end of the impeller 52 is fixedly connected to the drive motor 53.

[0032] As shown in the figure, the second drive motor 53 is electrically connected to the controller 46. The electrical connection between the second drive motor 53 and the controller 46 enables the controller 46 to dynamically adjust the heat dissipation intensity based on the power data of the first drive motor 45, thus avoiding the energy waste of traditional constant speed heat dissipation.

[0033] As shown in the figure, there are two cooling devices 5, which are symmetrical to each other along the vertical central axis of the tension shaft 44. The layout of the two symmetrical cooling devices 5 and the dual drive motors 45 is precisely matched, which can provide independent heat dissipation for each motor and ensure that the heat dissipation effect is directly applied to the heat source.

[0034] A specific application of this embodiment is as follows: The operator connects the power supply to the winding machine body 1 and starts the equipment via the controller 46. The winding shaft 2 and winding shaft 3 rotate synchronously, starting the winding operation of the packaging bag. The two drive motors 45 initialize, driving the threaded rod 42 to rotate, causing the threaded sleeve 43 to drive the tension shaft 44 to rise to a preset initial height, providing basic tension for the packaging bag. The controller 46 reads the initial power data of the two drive motors 45 in real time and sends a command to the drive motor 53 based on the initial power. The drive motor 53 drives the impeller 52 to start, providing basic cooling airflow for the drive motor 45. During the winding process, the two controllers 46 continuously collect the operating power of the corresponding drive motor 45, inferring the current tension on the packaging bag from the motor power. The controller 46 then transmits the power data of the two drive motors 45. If the power difference exceeds the threshold, it indicates that the tensioning shaft 44 is under uneven force. The controller 46 sends an adjustment command to the drive motor 45 on the deviation side. By fine-tuning the speed of the threaded rod 42, the lifting and lowering amplitude of the threaded sleeve 43 is changed to keep the tensioning shaft 44 horizontal, ensuring that the tension on both sides of the packaging bag is consistent. The anti-slip sleeve 47 on the surface of the tensioning shaft 44 enhances the friction with the packaging bag, preventing the packaging bag from slipping when the winding speed changes or the tension is adjusted. This ensures that the tension inferred by the controller 46 is consistent with the tension actually acting on the packaging bag, ensuring the smoothness of the winding. The controller 46 continuously compares the real-time power of the drive motor 45 with the preset threshold. When the motor power is low, the drive motor 53 is controlled to run at a low speed, and the impeller 52 dissipates heat with a low air volume to save energy. When the motor power increases, the drive motor 53 speeds up, and the impeller 52 increases the heat dissipation air volume to enhance the cooling effect.
