Description

Technical Field

[0001] This utility model relates to the field of fabric rolling machine technology, and in particular to a fabric rolling machine buffer device and a fabric rolling machine. Background Technology

[0002] In traditional circular knitting machines, after the fabric is woven, it is wound up by a fabric winding machine, and then the wound fabric roll is pushed onto a receiving rack and transported to the storage area. In actual production, fabric rolls can weigh hundreds of kilograms. As the fabric roll is fed out of the winding machine along the guide table, a huge impact force is generated. If the cushioning device of the winding machine cannot completely absorb the kinetic energy generated by the impact, the fabric roll will rebound, potentially causing impact damage to the winding machine. Furthermore, in actual production, fabric rolls of different diameters may be produced according to requirements, resulting in different center-of-gravity heights and different directions of impact force. Therefore, how to cushion the impact force generated when the fabric roll is fed out of the winding machine is the problem that this application aims to solve. Utility Model Content

The blocking mechanism is located in front of the guide table. The buffer mechanism is located on the guide table and is fixedly connected to the blocking mechanism. When the fabric roll moves along the guide table and toward the front of the guide table, the blocking mechanism moves with the fabric roll toward the front of the guide table. The buffer mechanism provides a buffering force to the blocking mechanism in the opposite direction to its movement.

[0005] Preferably, the blocking mechanism includes two buffer roller mounting plates and two buffer rollers. The two buffer roller mounting plates are arranged in parallel in front of the guide table and are fixedly connected to the buffer mechanism.

Detailed Implementation

[0018] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. The accompanying drawings are merely illustrative to facilitate understanding of the present invention, and their specific proportions can be adjusted according to design requirements. The vertical relationships of relative elements and the definitions of front / back in the graphics described herein should be understood by those skilled in the art to refer to the relative positions of the components; therefore, they can all be flipped to present the same component, and all of this should fall within the scope disclosed in this specification.

[0019] refer to Figures 1 to 6 This application proposes a fabric roll buffering device for a fabric rolling machine, including a guide platform 1, a blocking mechanism 2, and a buffering mechanism 3. The blocking mechanism 2 is located in front of the guide platform 1. Specifically, the blocking mechanism 2 includes two buffer roller mounting plates 21 and two buffer rollers 22. The two buffer roller mounting plates 21 are arranged parallel to each other in front of the guide platform 1. The buffering mechanism 3 is located on the guide platform 1 and is fixedly connected to the buffer roller mounting plates 21. When the fabric roll moves along the guide platform 1 and toward the front of the guide platform 1, the blocking mechanism 2 moves forward with the fabric roll. Under the impact of the fabric roll, the blocking mechanism translates to trigger the buffering mechanism to provide a buffering force. Specifically, the buffering mechanism 3 provides a buffering force to the buffer roller mounting plates 21 in the opposite direction to their movement. The fabric roll buffering device proposed in this application buffers the fabric roll by converting the impact force of the fabric roll into the kinetic energy of the blocking mechanism 2 moving forward toward the guide platform 1 and the potential energy of the buffering mechanism 3, thereby preventing the impact force of the fabric roll from damaging the fabric rolling machine.

[0020] In a specific embodiment, the buffer roller mounting plate 21 is provided with strip-shaped mounting grooves 211. The two ends of the buffer roller 22 are respectively mounted in the mounting grooves 211 of the two buffer roller mounting plates 21 by screws. The two buffer rollers 22 are spaced vertically apart, and the spacing between the two buffer rollers 22 can be changed by adjusting their mounting positions within the mounting grooves 211. In a specific embodiment, the two buffer rollers 22 are located on the upper and lower sides of the fabric roll's axis, respectively. By setting buffer rollers 22 with adjustable spacing and mounting height, different diameter fabric rolls can be accommodated, thereby improving the cushioning effect against impact forces on the fabric roll.

[0021] In a specific embodiment, refer to Figure 2 The blocking mechanism 2 also includes a connecting plate 23 and a buffer pad 24. Two buffer roller mounting plates 21 are respectively installed at both ends of the connecting plate 23. The buffer pad 24 is installed on the side of the connecting plate 23 facing the guide table 1. When the blocking mechanism 2 is in the reset state, the buffer pad 24 abuts against the front end of the guide table 1. Specifically, the buffer pad 24 is a rubber pad. When the cloth roll is moved away from the guide table 1 to reset the blocking mechanism 2, the connecting plate 23 and the buffer roller mounting plate 21 move toward the guide table 1 under the action of the buffer mechanism 3, which may cause an impact on the guide table 1. The buffer pad 24 is set to avoid the connecting plate 23 and the buffer roller mounting plate 21 directly impacting and damaging the guide table 1.

[0022] In a specific embodiment, the contact surface between the buffer roller 22 and the fabric roll is an arc-shaped surface. Since the fabric roll is cylindrical, the arc-shaped surface of the buffer roller 22 can increase the contact area between the buffer roller 22 and the fabric roll. Preferably, the buffer roller 22 can adopt a cylindrical structure, with its side contacting the fabric roll, which facilitates installation and use. Furthermore, the outer side of the buffer roller 22 is covered with an elastic layer to enhance the buffering effect of the buffer roller 22 on the fabric roll.

[0023] In a specific embodiment, refer to Figure 3 Two buffer mechanisms 3 are provided, arranged side by side on both sides of the bottom surface of the guide platform 1. Each buffer mechanism 3 includes an elastic element 31, a buffer rod 32, and a bushing 33. Four buffer rod mounting seats 11 are provided at the bottom of the guide platform 1. Each buffer rod 32 passes through the elastic element 31 and two buffer rod mounting seats 11 in sequence. One end of the buffer rod 32 is fixedly connected to the elastic element 31, and the other end is fixedly connected to the blocking mechanism 2. The bushing 33 is mounted on the buffer rod mounting seat 11 and sleeved on the outside of the buffer rod 32. By guiding the buffer rod 32 through the two buffer rod mounting seats 11 and the bushing 33, the buffering effect of the buffer mechanism 3 on the impact force of the fabric roll is maximized, improving buffering efficiency.

[0024] In a specific embodiment, a weighing sensor 4 is also included. The guide table 1 includes an inclined section 12 and a platform section 13. The platform section 13 is located in front of the inclined section 12. The weighing sensor 4 is installed on the platform section 13 so that the fabric roll can be weighed directly after it stops on the platform section 13, which is convenient to use.

[0025] A fabric rolling machine includes two fabric roll buffer devices as described above. The two fabric roll buffer devices are spaced apart along the axial direction of the fabric roll, so that the center of gravity of the fabric roll is located between the two fabric roll buffer devices, and the two fabric roll buffer devices can buffer the fabric roll at the same time to improve the buffering effect.

[0026] The following is a detailed explanation of the application process.

[0027] The fabric is wound up by a fabric winding machine to obtain a fabric roll. Figure 4 and Figure 5 The middle fabric roll is a first fabric roll 51 with a first diameter. The first fabric roll 51 is fed out of the fabric rolling machine along the inclined section 12 of the guide table 1. Figure 4 This is the state when the first fabric roll 51 just comes into contact with the blocking mechanism 2. At this time, the first fabric roll 51 abuts against the sides of the two buffer rollers 22, and the first fabric roll 51 applies a pushing force to the blocking mechanism 2 in the direction of the guide table 1, thereby driving the blocking mechanism 2 to move in the direction of the guide table 1. (Reference) Figure 5 When the first fabric roll 51 and the blocking mechanism 2 move forward toward the guide table 1, the blocking mechanism 2 drives the buffer rod 32 of the buffer mechanism 3 to move. The elastic element 31 is in a compressed state, and the elastic element 31 applies a spring force to the buffer rod 32 in the opposite direction to its movement. Therefore, the buffer rod 32 applies a buffering force to the buffer roller mounting plate 21 in the opposite direction to its movement, thereby converting the impact force of the first fabric roll 51 into the kinetic energy of the blocking mechanism 2 moving forward toward the guide table 1 and the elastic potential energy of the elastic element 31, thus buffering the first fabric roll 51 and preventing the impact force of the second fabric roll 52 from damaging the fabric rolling machine. After the second fabric roll 52 is buffered by the fabric roll buffering device and stops on the platform section 13, it can be weighed using the weighing sensor 4, and the weighing data can be recorded. (Reference) Figure 6 , Figure 6 The fabric roll in the first fabric roll 51 is a second fabric roll 52 with a second diameter larger than the first diameter. Therefore, the center of gravity of the second fabric roll 52 is higher than that of the first fabric roll 51. The center of gravity of the fabric roll is usually located near its axis. Before producing the second fabric roll 52, the positions of the two buffer rollers 22 on the mounting groove 211 can be adjusted so that when the fabric roll buffer device is working, the two buffer rollers 22 are located on the upper and lower sides of the axis of the fabric roll, respectively, to ensure that the center of gravity of the second fabric roll 52 is located between the two buffer rollers 22, thereby ensuring the buffering effect.

Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of the technical solution of this utility model.
