Description

Technical Field

[0001] This utility model relates to the field of weighing technology, specifically to an unwinding weighing device for a winding machine. Background Technology

[0002] In many industrial production fields such as metal processing and papermaking, the winding machine is an important piece of equipment, undertaking the crucial task of winding the produced strip materials into rolls. After winding, unwinding the roll and accurately weighing it are indispensable steps in subsequent processes.

[0003] Currently, in traditional winding machine systems, unwinding and weighing are performed by two independent devices. The unwinding device is mainly responsible for smoothly unloading the wound material from the winding shaft and transporting it to a designated location. Its structural design often focuses on mechanical transmission and the gripping and conveying functions of the wound material. The weighing device, on the other hand, is independently located downstream of the unwinding device's transport path. It is used to measure the weight of the unwound material to control product quality and arrange subsequent logistics.

[0004] This equipment configuration, which separates unloading and weighing, has revealed a series of significant drawbacks in actual production. Firstly, the two independent units greatly increase the floor space required, posing a significant challenge for companies with limited production space. This not only leads to a cramped production layout but also increases the difficulty of workshop planning and management. Secondly, because unloading and weighing are performed in stages, materials need to be moved multiple times between different units. This not only prolongs the production cycle and reduces efficiency but also poses a risk of material damage during handling. For example, collisions or bumps may cause scratches or deformation on the surface of the material, affecting product quality. Furthermore, the purchase, installation, commissioning, and subsequent maintenance of multiple units significantly increase the company's equipment procurement and operating costs, hindering economic efficiency.

[0005] Therefore, developing a winding unwinding and weighing device for winding machines that can organically integrate unwinding and weighing functions to overcome the above-mentioned defects in the existing technology has become an important technical problem that needs to be solved urgently in related fields. Utility Model Content

[0006] To address the aforementioned problems, this invention provides a winding unloading and weighing device for a winding machine.

[0007] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0008] A winding unloading and weighing device for a winding machine includes a base plate. Bases are provided on both the left and right sides of the top wall of the base plate. A limiting groove is formed on the upper surface of the base. A housing is provided in the middle of the top wall of the base plate. A motor is provided on the front side of the inner bottom wall of the housing. A lead screw is locked to the output end of the motor via a coupling. The rear end wall of the lead screw is rotatably connected to the inner wall of the housing via a bearing. A connecting block is threaded onto the outer wall of the lead screw. A connecting rod is provided on the top wall of the connecting block. The top wall of the connecting rod extends out of the housing and is provided with a connecting plate. Multiple support wheels are provided on both the left and right sides of the bottom wall of the connecting plate. Weighing sensors are provided at the four corners of the top wall of the connecting plate. Top seats are provided on the top walls of the multiple weighing sensors. An arc-shaped groove is formed on the top wall surface of the top seat, and multiple anti-slip pads are provided on the inner wall of the arc-shaped groove.

[0009] Furthermore, the upper end face of the shell is provided with an elongated hole communicating with the inner cavity.

[0010] Furthermore, the outer ring of the bearing is fixedly connected to the inner wall of the housing through the bearing seat, and the inner ring of the bearing is interference-fitted with the outer wall of the lead screw.

[0011] Furthermore, the support wheels are distributed at the four corners of the bottom end of the connecting plate, and the support wheels are rotatably connected in the limiting groove.

[0012] Furthermore, the anti-slip pads are arranged with gaps from front to back on the top seat.

[0013] The beneficial effects of this utility model are:

[0014] This utility model integrates unwinding and weighing functions into one unit, eliminating the complex configuration of two separate devices in the traditional system. This greatly reduces the floor space occupied by the equipment. For companies with limited production space, this can effectively alleviate the congestion in the production layout, reduce the difficulty of workshop planning and management, and free up more valuable production space for the company.

[0015] This device simultaneously completes the weighing operation during the unwinding process, eliminating the cumbersome intermediate handling steps. The motor-driven screw drives the connecting block and other structures to quickly unload the roll from the winding mechanism roller and weigh it, significantly shortening the production cycle and greatly improving the overall production efficiency.

[0016] From an equipment procurement perspective, an integrated device reduces hardware purchase costs compared to two independent devices. During installation and commissioning, the process is simplified due to the reduced number of devices, reducing the investment of manpower and resources. In later maintenance, only one set of devices needs to be maintained, which significantly reduces the company's operating and maintenance costs and improves the company's economic benefits.

[0022] 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.

[0023] See Figure 1-2 As shown, a winding unloading weighing device for a winding machine includes a base plate 1. Bases 2 are provided on both the left and right sides of the top wall of the base plate 1. A limit groove 3 is formed on the upper surface of the base 2. A housing 4 is provided in the middle of the top wall of the base plate 1. A motor 5 is provided on the front side of the inner bottom wall of the housing 4. A lead screw 6 is locked to the output end of the motor 5 via a coupling. The rear end wall of the lead screw 6 is rotatably connected to the inner wall of the housing 4 via a bearing 7. A connecting block 8 is threaded onto the outer wall of the lead screw 6. A connecting rod 9 is provided on the top wall of the connecting block 8. The top wall of the connecting rod 9 extends out of the housing 4 and is provided with a connecting plate 10. Multiple support wheels 11 are provided on both the left and right sides of the bottom wall of the connecting plate 10. Weighing sensors 12 are provided at the four corners of the top wall of the connecting plate 10. Top seats 13 are provided on the top walls of the multiple weighing sensors 12. An arc-shaped groove is formed on the top wall of the top seat 13, and multiple anti-slip pads 14 are provided on the inner wall of the arc-shaped groove.

[0024] Furthermore, the upper end face of the housing 4 is provided with an elongated hole communicating with the inner cavity. After the motor 5 is started, the lead screw 6 is rotated. The lead screw 6 causes the connecting block 8 to drive the connecting rod 9, the connecting plate 10, the support wheel 11, the weighing sensor 12, the top seat 13, the anti-slip pad 14, and the rolled material to move to the rear. The elongated hole is used for the movement of the connecting rod 9.

[0025] Furthermore, the outer ring of the bearing 7 is fixedly connected to the inner wall of the housing 4 through the bearing seat, and the inner ring of the bearing 7 is interference-fitted with the outer wall of the lead screw 6. The bearing 7 fixes the lead screw 6, making it easier for the lead screw 6 to rotate through the bearing 7.

[0026] Furthermore, the support wheels 11 are distributed at the four corners of the bottom of the connecting plate 10, and the support wheels 11 are rotatably connected in the limiting groove 3. The support wheels 11 support the connecting plate 10, preventing the weight on the connecting plate 10 from being directly applied to the lead screw 6, which would cause the lead screw 6 to bend and be damaged.

[0027] Furthermore, the anti-slip pads 14 are arranged at intervals from front to back on the top seat 13 to increase the friction when the top seat 13 comes into contact with the coil.

[0028] For those skilled in the art, all electrical components and parts in this case are general standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. All models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires. According to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.

[0029] One specific application of this embodiment is:

[0030] In actual use, the installation and operation process of this unloading weighing device for the winding machine is clear and efficient. First, the device is precisely installed in the original position of the unloading device of the winding machine to ensure that the anti-slip pad 14 is precisely located directly below the winding mechanism. The accuracy of this installation position is crucial for the subsequent receiving and processing of the roll material.

[0031] After the winding machine completes the winding process, the winding mechanism smoothly places the wound material onto the anti-slip mat 14 according to the preset program. At this time, the motor 5 is started and starts to run and output power, causing the lead screw 6 to rotate at high speed and stably under its drive. The rotational motion of the lead screw 6 is converted into linear motion, pushing the connecting block 8 to move backward along the axial direction of the lead screw 6. Since there is a stable connection structure between the connecting block 8 and the connecting rod 9, the connecting plate 10, the support wheel 11, the weighing sensor 12, the top seat 13 and the anti-slip mat 14, the movement of the connecting block 8 will drive all the above components to move backward synchronously, and the material will also move together.

[0032] During this movement, the support wheel 11 plays a crucial role. The support wheel 11 is in close contact with the ground, and its rolling friction is much less than its sliding friction. It can easily bear the weight of the connecting plate 10 and the coiled material and other components placed on it, thereby preventing the weight on the connecting plate 10 from being directly and vertically applied to the lead screw 6. Without the support of the support wheel 11, the lead screw 6 would have to rotate while bearing huge vertical pressure, which would easily lead to bending and damage. This would seriously affect the normal operation and service life of the equipment.

[0033] As the components continue to move, the top seat 13 gradually approaches the roller of the winding mechanism and eventually contacts the coil. During the subsequent movement, the top seat 13, relying on its own structural strength and power transmission, steadily drives the coil to continue moving backward, thus successfully unloading the coil from the roller of the winding mechanism. When the coil is completely detached from the roller, it is positioned directly above the weighing sensor 12. The weighing sensor 12 immediately starts working, accurately weighing the coil and obtaining its real-time weight data.

[0034] After completing the weighing operation and obtaining accurate weight data, the operator can easily remove the roll from the top seat 13, completing the entire unwinding and weighing process. The device can then enter the next work cycle to continue serving production operations.

[0035] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, alterations, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
