Description

Technical Field

[0001] This utility model relates to the field of fabric winding technology, and in particular to a material changing device. Background Technology

[0002] In the field of fabric production technology, after fabric production is completed, it needs to be wound. Traditional fabric winding equipment is usually equipped with only one winding roller, which is connected to a drive mechanism for winding. When only one winding roller is provided, after the fabric roll on the winding shaft is finished, the machine needs to be stopped to unload the material and replace it with a new winding drum, resulting in low production efficiency.

[0003] To address the aforementioned issues, current methods in the field involve assembling two winding shafts and corresponding drive mechanisms on the winding equipment. This allows the fabric roll on one winding shaft to be wound onto the other, unwound shaft after it has been wound up. Simultaneously, the operator can unload the wound fabric roll. However, this method requires manual cutting and assistance in switching the fabric to different winding shafts, making the operation cumbersome. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a material changing device to reduce the difficulty of changing the winding shaft of the fabric.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A material changing device is disposed at the unloading end of a winding equipment, the winding equipment including at least two parallel winding mechanisms, and the material changing device including an ultrasonic welding mechanism, a translation mechanism, and a guide assembly for guiding the fabric.

[0007] The ultrasonic welding mechanism and the guide assembly are both located below the winding mechanism, and the fabric to be wound can pass through the surface of the guide assembly and be wound onto one of the winding mechanisms.

[0008] The ultrasonic welding mechanism and the guide assembly are disposed at the movable end of the translation mechanism, and the direction of movement of the translation mechanism is perpendicular to the axis of the winding mechanism, so that the ultrasonic welding mechanism and the guide assembly can move relative to the winding mechanism.

[0009] The welding end of the ultrasonic welding mechanism can press against or separate from the guide component.

[0010] Furthermore, in the vertical direction, the projection areas of two adjacent winding mechanisms are located within the projection area of ​​the guide assembly's range of motion.

[0011] Furthermore, the guiding assembly includes a first guide roller and a second guide roller that are parallel to each other;

[0012] The first guide roller and the second guide roller are spaced apart;

[0013] In the direction of movement of the translation mechanism, the ultrasonic welding mechanism is located on the side of the second guide roller away from the first guide roller.

[0014] Furthermore, the top surface of the welding end of the ultrasonic welding mechanism is lower than the lowest point of the second guide roller, or the top surface of the welding end of the ultrasonic welding mechanism is flush with the lowest point of the second guide roller, so that the welding end of the ultrasonic welding mechanism can press against or separate from the first guide roller.

[0015] Furthermore, the ultrasonic welding mechanism includes an ultrasonic welding machine and a position adjustment mechanism;

[0016] The position adjustment mechanism is disposed on the translation mechanism;

[0017] The fixed end of the ultrasonic welding machine is connected to the movable end of the position adjustment mechanism via a transmission connection.

[0018] Furthermore, the ultrasonic welding machine includes an ultrasonic generator and a welding head;

[0019] The welding head is connected to the ultrasonic generator, and the top of the welding head near the first guide roller has a welding groove.

[0020] Furthermore, the cross-section of the welding groove is arc-shaped.

[0021] Furthermore, multiple ultrasonic welding machines and position adjustment mechanisms are provided, with each ultrasonic welding machine corresponding to one of the position adjustment mechanisms.

[0022] Furthermore, the winding device includes a support;

[0023] The winding mechanism is located at the top of the bracket, and the translation mechanism is located at the bottom of the bracket.

[0024] Furthermore, the translation mechanism includes a moving platform, a slide rail, and a linear drive mechanism;

[0026] The fixed end of the linear drive mechanism is connected to the bracket, and the movable end of the linear drive mechanism is connected to the mobile platform via transmission.

[0027] The ultrasonic welding mechanism and the guiding component are respectively mounted on the mobile platform.

[0028] The beneficial effects of this utility model are as follows: by cooperating with the ultrasonic welding mechanism and the guide component, the fabric on one of the winding mechanisms (in a winding state) and the fabric on the target winding mechanism (to be wound) are welded on the surface of the guide component by the ultrasonic welding mechanism. This allows the fabric on the production line to be quickly connected with a small amount of fabric on the winding mechanism to be wound, thereby realizing the rapid switching of the winding mechanism and reducing the operational difficulty when switching the winding mechanism. At the same time, the use of the ultrasonic welding mechanism can ensure the flatness of the connection. Attached Figure Description

Detailed Implementation

[0033] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0034] Please refer to Figure 1 as well as Figure 2 A material changing device is provided, which is located at the unloading end of a winding equipment. The winding equipment includes at least two parallel winding mechanisms 1. The material changing device includes an ultrasonic welding device 2, a translation mechanism 3, and a guide component 4 for guiding the fabric. The ultrasonic welding device 2 and the guide component 4 are both located below the winding mechanism 1. The fabric 5 to be wound can pass through the surface of the guide component 4 and be wound onto one of the winding mechanisms 1. The ultrasonic welding device 2 and the guide component 4 are located at the movable end of the translation mechanism 3, and the direction of movement of the translation mechanism 3 is perpendicular to the axis of the winding mechanism 1, so that the ultrasonic welding device 2 and the guide component 4 can move relative to the winding mechanism 1. The welding end of the ultrasonic welding device 2 can press against or separate from the guide component 4.

[0035] It is worth noting that the fabric mentioned in this utility model refers to synthetic fiber fabrics or plastic films that can be ultrasonically welded.

[0036] It is understandable that by cooperating with the ultrasonic welding device 2 and the guide component 4, the fabric on one of the winding mechanisms 1 (in a winding state) and the fabric on the target winding mechanism 1 (to be wound) are welded on the surface of the guide component 4 by the ultrasonic welding device 2. This allows the fabric to be wound 5 on the production line to be quickly connected with a small amount of fabric on the target winding mechanism 1, thereby realizing the rapid switching of the winding mechanism 1 and reducing the operational difficulty when switching the fabric to the winding mechanism 1. At the same time, the use of the ultrasonic welding device 2 can ensure the flatness of the connection.

[0037] In some embodiments, in the vertical direction, the projection areas of two adjacent winding mechanisms 1 are located within the projection area of ​​the guide component 4's active range. This ensures that the guide component 4 can move the fabric that has not yet been switched to below the target winding mechanism 1, and then weld it to the small amount of fabric on the target winding mechanism 1, ensuring the reliability of the fabric switching winding mechanism 1. Specifically, the projection areas of the two winding mechanisms 1 refer to the vertical projection of the two winding mechanisms 1 and the space between them.

[0038] In some embodiments, the guiding assembly 4 includes a first guide roller 41 and a second guide roller 42 that are parallel to each other; the first guide roller 41 and the second guide roller 42 are spaced apart; in the direction of movement of the translation mechanism 3, the ultrasonic welding device 2 is disposed on the side of the second guide roller 42 away from the first guide roller 41. The first guide roller 41 is configured to cooperate with the ultrasonic welding device 2 to quickly weld two pieces of fabric, while the second guide roller 42 is configured to support the fabric and prevent the fabric from contacting the ultrasonic welding device 2 during the winding process. Specifically, the first guide roller 41 and the second guide roller 42 are parallel to each other with the two winding mechanisms 1 respectively. When the fabric is wound on the winding mechanism 1 inside the winding equipment, the fabric presses against the surface of the first guide roller 41, and at the same time, the fabric separates from the second guide roller 42. When the fabric is wound on the winding mechanism 1 outside the winding equipment, the fabric presses against the surface of the second guide roller 42.

[0039] In some embodiments, the top surface of the welding end of the ultrasonic welding device 2 is lower than the lowest point of the second guide roller 42, or the top surface of the welding end of the ultrasonic welding device 2 is flush with the lowest point of the second guide roller 42, so that the welding end of the ultrasonic welding device 2 can press against or separate from the first guide roller 41. Specifically, during the fabric switching and winding mechanism 1, the welding end of the ultrasonic welding device 2 should pass through the space below the second guide roller 42 and press against the first guide roller 41, so that the fabric is welded on the surface of the first guide roller 41. Preferably, the top surface of the welding end of the ultrasonic welding device 2 is lower than the lowest point of the second guide roller 42 to avoid friction between the welding end of the ultrasonic welding device 2 and the second guide roller 42.

[0040] In some embodiments, the ultrasonic welding apparatus 2 includes an ultrasonic welding machine 21 and a position adjustment mechanism 22; the position adjustment mechanism 22 is disposed on the translation mechanism 3; the fixed end of the ultrasonic welding machine 21 is connected to the movable end of the position adjustment mechanism 22 via a transmission connection. The position adjustment mechanism 22 is configured to change the relative positional relationship between the ultrasonic welding machine 21 and the first guide roller 41, so that the ultrasonic welding machine 21 presses against the first guide roller 41 when welding is required, and moves away from the first guide roller 41 and the second guide roller 42 when welding is not required, thereby preventing the ultrasonic welding machine 21 from contacting the fabric during the fabric conveying process and causing damage to the fabric.

[0041] In some embodiments, the ultrasonic welding machine 21 includes an ultrasonic generator 211 and a welding head 212; the welding head 212 is connected to the ultrasonic generator 211, and the top of the welding head 212 has a welding groove 2121 near the first guide roller 41. Preferably, the cross-section of the welding groove 2121 is arc-shaped, and the curvature of the welding groove 2121 should match the surface curvature of the first guide roller 41 to improve the fit of the welding surfaces and ensure that the two pieces of fabric are effectively welded.

[0042] In some embodiments, multiple ultrasonic welding machines 21 and position adjustment mechanisms 22 are provided, with each ultrasonic welding machine 21 corresponding to a position adjustment mechanism 22 to achieve independent control of each welding position. Welding can be performed on different positions of the fabric according to actual needs, thus improving flexibility.

[0043] In some embodiments, the winding device includes a support 6; a winding mechanism 1 is disposed on the top of the support 6, and a translation mechanism 3 is disposed on the bottom of the support 6.

[0044] In some embodiments, the translation mechanism 3 includes a moving platform 31, a slide rail 32, and a linear drive mechanism 33. The moving platform 31 is slidably connected to the support 6 via the slide rail 32. The fixed end of the linear drive mechanism 33 is connected to the support 6, and the movable end of the linear drive mechanism 33 is driveably connected to the moving platform 31. The ultrasonic welding device 2 and the guide assembly 4 are respectively disposed on the moving platform 31. Optionally, the linear drive mechanism 33 can be a screw drive mechanism, a linear servo module, a linear push rod, or a cylinder; preferably, the linear drive mechanism 33 is a screw drive mechanism. Specifically, both the linear drive mechanism 33 and the slide rail 32 are disposed at the bottom of the moving platform 31. Through the cooperation of the linear drive mechanism 33 and the moving platform 31, the position of the guide assembly 4 can be controlled, thereby driving the fabric in the winding state to move below the target winding mechanism 1, so as to facilitate fabric welding and improve the reliability and efficiency of the fabric switching process.

The ultrasonic welding device 2 and the guide component 4 are both located below the winding mechanism 1.

The ultrasonic welding device 2 and the guide component 4 are located at the movable end of the translation mechanism 3, and the direction of movement of the translation mechanism 3 is perpendicular to the axis of the winding mechanism 1, so that the ultrasonic welding device 2 and the guide component 4 can move relative to the winding mechanism 1. The welding end of the ultrasonic welding device 2 can press against or separate from the guide component 4.

[0047] In this embodiment, in the vertical direction, the projection areas of two adjacent winding mechanisms 1 are located within the projection area of ​​the active range of the guide component 4.

[0048] In this embodiment, the guiding assembly 4 includes a first guide roller 41 and a second guide roller 42 that are parallel to each other; the first guide roller 41 and the second guide roller 42 are spaced apart; in the direction of movement of the translation mechanism 3, the ultrasonic welding device 2 is disposed on the side of the second guide roller 42 away from the first guide roller 41. The first guide roller 41 can be moved directly below any of the winding mechanisms 1.

[0049] In this embodiment, the top surface of the welding end of the ultrasonic welding device 2 is lower than the lowest point of the second guide roller 42, so that the welding end of the ultrasonic welding device 2 can press against or separate from the first guide roller 41.

[0050] In this embodiment, the ultrasonic welding device 2 includes an ultrasonic welding machine 21 and a position adjustment mechanism 22; the position adjustment mechanism 22 is mounted on the translation mechanism 3; the fixed end of the ultrasonic welding machine 21 is connected to the movable end of the position adjustment mechanism 22 via a transmission connection. Preferably, the position adjustment component is a linear slide module, which can be a lead screw slide or a synchronous belt slide.

[0051] In this embodiment, the ultrasonic welding machine 21 includes an ultrasonic generator 211 and a welding head 212; the welding head 212 is connected to the ultrasonic generator 211, and the top of the welding head 212 near the first guide roller 41 has a welding groove 2121. Preferably, the cross-section of the welding groove 2121 is arc-shaped, and the curvature of the welding groove 2121 should match the surface curvature of the first guide roller 41.

[0052] In this embodiment, multiple ultrasonic welding machines 21 and position adjustment mechanisms 22 are provided, with each ultrasonic welding machine 21 corresponding to a position adjustment mechanism 22.

[0053] In this embodiment, the winding device includes a support 6; a winding mechanism 1 is disposed on the top of the support 6, and a translation mechanism 3 is disposed on the bottom of the support 6. The translation mechanism 3 includes a moving platform 31, a slide rail 32, and a linear drive mechanism 33; the moving platform 31 is slidably connected to the support 6 via the slide rail 32; the fixed end of the linear drive mechanism 33 is connected to the support 6, and the movable end of the linear drive mechanism 33 is driveably connected to the moving platform 31; the ultrasonic welding device 2 and the guide assembly 4 are respectively disposed on the moving platform 31. Preferably, the linear drive mechanism 33 is a screw drive mechanism. Specifically, both the linear drive mechanism 33 and the slide rail 32 are disposed on the bottom of the moving platform 31, and the fixed end of the position adjustment mechanism 22 is disposed on the moving platform 31.

[0054] The working principle of this utility model is as follows:

[0055] The following explanation will be based on the example of a winding mechanism 1 in which the fabric is wound inside the winding equipment.

[0056] When the fabric roll on the winding mechanism 1 is about to finish winding, the translation mechanism 3 drives the guide assembly 4 to move toward the side where the target winding mechanism 1 is located, until the first guide roller 41 of the guide assembly 4 moves to the bottom of the target winding mechanism 1. Before switching the winding mechanism 1, a small amount of the same fabric is manually wound on the target winding mechanism 1 so that the fabric on the target winding mechanism 1 hangs down to the position of the first guide roller 41.

[0057] Both winding mechanisms 1 stop operating. The position adjustment mechanism 22 controls the ultrasonic welding machine 21 to move towards the first guide roller 41, so that the fabric in the winding state and the fabric on the target winding mechanism 1 are simultaneously clamped between the welding head 212 of the ultrasonic welding machine 21 and the first guide roller 41. The ultrasonic welding machine 21 welds the two sections of fabric. After the welding is completed, the fabric in the winding state is manually cut off, and the target winding mechanism 1 is started, so that the fabric on the production line is wound onto the target winding mechanism 1.
