Description

Technical Field

[0001] This utility model relates to the field of ultrasonic lace machine technology, specifically to a mop wheel device, and also to an ultrasonic lace machine using the mop wheel device. Background Technology

[0002] An ultrasonic lace machine is a device that uses high-frequency ultrasonic vibration energy to perform functions such as welding, sewing, embossing, and slitting of materials. It is widely used in industries such as textiles, clothing, medical, environmental protection, and automotive interiors. Its core principle is to generate high-frequency oscillation signals through an ultrasonic generator, which are converted into mechanical vibrations by a transducer. The vibration energy is then transferred to the surface of the material to be processed through a welding head, causing intense friction and heat generation between material molecules, thereby achieving localized melting and bonding or cutting.

[0003] In existing ultrasonic lace machines, a drag-roller structure is typically used to facilitate automatic control of fabric movement. This drag-roller structure consists of two rotating wheels that work together to form a channel for holding the fabric. The rotation of the wheels provides traction to the fabric, thus moving it to complete the printing operation at different positions. Each time the fabric is changed, the distance between the two rotating wheels needs to be adjusted so that the fabric can fit into the channel. The current method for adjusting the distance between the two rotating wheels involves a motor controlling one wheel to move closer to or further away from the other, thus achieving automated control. However, after adjustment, the distance between the two rotating wheels is fixed. If the same fabric has different thicknesses, the thicker parts are prone to jamming or damaging the fabric. Furthermore, controlling the distance between the two rotating wheels via a motor requires the installation of motors and sensors, resulting in high costs.

[0004] Therefore, a more optimized mop roller structure needs to be considered. Utility Model Content

[0005] The primary objective of this invention is to provide a mop wheel device that enables dynamic adjustment of the pressure exerted by the mop wheel on the fabric.

[0006] The second objective of this invention is to provide an ultrasonic lace machine that can dynamically adjust the pressure of the drag roller pressing the fabric.

[0007] To achieve the above-mentioned main objectives, the mop wheel device provided by this utility model includes a mop wheel, a fixed frame, a spring assembly, and a connecting seat. The mop wheel is rotatably mounted on the fixed frame, and the fixed frame is connected to the connecting seat through the spring assembly. The mop wheel can move along the extension and retraction direction of the spring assembly.

[0008] As can be seen from the above scheme, the mop roller device of this utility model installs the mop roller with a spring assembly, allowing the mop roller to move along the extension and retraction direction of the spring assembly. Under the pressure of the spring assembly, the mop roller is in close contact with the material surface and rotates with the fabric feeding direction, driving the material forward at a uniform speed through friction. When the material thickness is uneven, the height of the mop roller is automatically adjusted by the extension and retraction of the spring, which can realize dynamic adjustment of the pressure of the mop roller on the fabric, reduce rigid compression on the fabric, avoid jamming or damage to the fabric, and ensure the uniformity of processing.

[0009] In a further embodiment, the spring assembly includes a first connecting post, a second connecting post, a spring element, and a spring limiting element. The spring limiting element is mounted on a connecting seat. The spring limiting element has a spring mounting groove, a first mounting hole at the bottom of the spring mounting groove, and a second mounting hole at the top of the spring mounting groove. The first end of the first connecting post is inserted into the spring mounting groove through the first mounting hole. A protrusion is provided on the outer peripheral wall of the first end of the first connecting post, which engages with the bottom of the spring mounting groove. The second end of the first connecting post is connected to a fixing frame. The first end of the first connecting post also has a receiving hole extending axially along the first connecting post. The first end of the second connecting post is installed in the second mounting hole, and the second end of the second connecting post is movably inserted into the receiving hole. The spring element is fitted onto the outer periphery of the second connecting post, with the first end of the spring element abutting against the top of the spring mounting groove and the second end of the spring element abutting against the first end of the first connecting post.

[0010] Therefore, the spring assembly, through the arrangement of a first connecting post, a second connecting post, a spring element, and a spring limiting element, with the spring element in a pre-compressed state, pushes the first connecting post to move the fixing frame and the mop roller away from the connecting seat, causing the mop roller to apply pressure to the fabric. When the mop roller receives the reaction force from the fabric, i.e., the fabric thickness increases, the first connecting post moves along the direction of spring element contraction, thereby adjusting the pressure of the mop roller on the fabric, thus achieving dynamic adjustment of the pressure of the mop roller on the fabric, allowing the fabric to pass smoothly. Furthermore, the second connecting post inserts into the receiving hole of the first connecting post, forming a sliding guide to prevent lateral displacement when the spring element is compressed, ensuring that the mop roller moves in a direction perpendicular to the material surface, improving pressure uniformity.

[0011] In a further embodiment, the mop wheel device also includes a cam and a limiting block. The cam is rotatably mounted on the connecting seat; the limiting block is mounted on the first connecting column, and the cam and the limiting block are configured to cooperate; the cam has a first rotation position and a second rotation position; when the cam rotates from the first rotation position to the second rotation position, the cam controls the first connecting column to move in the direction of extending into the spring mounting groove; when the cam rotates from the second rotation position to the first rotation position, the cam controls the first connecting column to move in the direction of exiting the spring mounting groove.

[0012] Therefore, by setting up a cam and a limit block in coordination, when it is necessary to change the fabric, the cam can be controlled to rotate, thereby lifting the mop roller and providing sufficient space for fabric replacement. After changing the fabric, the cam can be controlled to rotate, lowering the mop roller and thus pressing the fabric down.

[0013] In a further embodiment, the cam is mounted on the connector via a handle assembly, which in turn drives the cam to rotate.

[0014] Therefore, by setting up a handle assembly to control the rotation of the cam, it is possible to facilitate manual control of the mop roller.

[0015] In a further embodiment, the handle assembly includes a handle component, a rotating shaft, and a damping component. The handle component is connected to the first end of the rotating shaft, and the second end of the rotating shaft is connected to a cam. The connecting seat is provided with a handle mounting hole, and the rotating shaft is inserted into the handle mounting hole through the damping component.

[0016] As can be seen, the handle assembly, by setting a pivot and a damping element, with the pivot inserted into the handle mounting hole via the damping element, can use the resistance of the damping element to fix the cam in the required position.

[0017] In a further embodiment, the connector is provided with a receiving groove, and the spring assembly is installed in the receiving groove.

[0018] Therefore, the connector is provided with a receiving groove for installing the spring assembly, which can prevent the spring assembly from being exposed and reduce the risk of foreign objects getting stuck in the spring assembly, thus reducing the spring assembly's extension and contraction performance.

[0019] In a further embodiment, a connecting post guide hole is provided at the bottom of the receiving groove, and the first connecting post is inserted into the receiving groove through the connecting post guide hole.

[0020] Therefore, by setting a guide hole for the connecting column, the movement of the first connecting column can be guided, reducing the shaking of the first connecting column during movement and ensuring the stability of the pressure provided by the drag roller to the fabric.

[0021] In a further embodiment, a guide hole is provided at the bottom of the connector, which extends along the extension and retraction direction of the spring assembly; a guide post is installed on the fixing frame, and the guide post can be movably inserted into the guide hole.

[0022] Therefore, the guide hole at the bottom of the connecting seat is designed to guide and cooperate with the guide column on the fixed frame, which can ensure the stability of the fixed frame's movement and further improve the stability of the pressure applied to the fabric by the drag roller.

[0023] To achieve the second objective mentioned above, the ultrasonic lace machine provided by this utility model is equipped with a mop wheel device, which is the mop wheel device mentioned above. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0034] Example of an ultrasonic lace machine:

[0035] like Figure 1 and Figure 2 As shown, in this embodiment, the ultrasonic lace machine is equipped with a machine base 1, a machine head assembly 2, a fabric dragging wheel device 3, rollers 4, and a drive motor 5. The machine head assembly 2 is mounted on the machine base 1, and the fabric dragging wheel device 3 is mounted on the machine head assembly 2. The rollers 4 and the drive motor 5 are mounted at the bottom of the machine base 1, and the drive motor 5 is used to drive the rollers 4 to rotate. The fabric dragging wheel device 3 is configured to cooperate with the rollers 4 for dragging the fabric.

[0036] In this embodiment, see Figure 3 and Figure 4The mop roller assembly 3 includes a mop roller 31, a fixing frame 32, a spring assembly 33, and a connecting seat 34. The mop roller 31 is rotatably mounted on the fixing frame 32, and the fixing frame 32 is connected to the connecting seat 34 via the spring assembly 33. The connecting seat 34 is mounted on the machine head assembly 2. The mop roller 31 can move along the extension and retraction direction of the spring assembly 33.

[0037] See Figure 5 The connecting seat 34 is provided with a receiving groove 341, and the spring assembly 33 is installed in the receiving groove 341. By providing a receiving groove 341 in the connecting seat 34 for installing the spring assembly 33, the spring assembly 33 is prevented from being exposed, reducing the risk of foreign objects getting stuck in the spring assembly 33 and weakening its extension and contraction performance. See also Figure 6 The bottom of the connecting seat 34 is provided with a guide hole 342, which extends along the extension and retraction direction of the spring assembly 33. A guide post 321 is mounted on the fixing frame 32, and the guide post 321 is movably inserted into the guide hole 342. The guide hole 342 at the bottom of the connecting seat 34 and the guide post 321 on the fixing frame 32 provide guidance and cooperation, which can ensure the stability of the movement of the fixing frame 32 and improve the stability of the pressure applied by the drag roller 31 to the fabric.

[0038] In this embodiment, see Figure 7 The spring assembly 33 includes a first connecting post 331, a second connecting post 332, a spring member 333, a spring limiting member 334, and a connecting member 335. The spring limiting member 334 is mounted on the connecting seat 34 via the connecting member 335. The spring limiting member 334 is provided with a spring mounting groove 3341, a first mounting hole 3342 is provided at the bottom of the spring mounting groove 3341, and a second mounting hole 3343 is provided at the top of the spring mounting groove 3341. The first end of the first connecting post 331 is inserted into the spring mounting groove 3341 through the first mounting hole 3342. A flange 3312 is provided on the outer peripheral wall of the first end of the first connecting post 331, which is limited and engaged with the bottom of the spring mounting groove 3341. The second end of the first connecting post 331 is connected to the fixing frame 32 via a bolt (not shown). The first end of the first connecting post 331 is also provided with a receiving hole 3312 extending axially along the first connecting post 331. The first end of the second connecting post 332 is installed in the second mounting hole 3343, and the second end of the second connecting post 332 is movably inserted into the receiving hole 3312. The spring member 333 is fitted on the outer periphery of the second connecting post 332, the first end of the spring member 333 abuts against the top of the spring mounting groove 3341, and the second end of the spring member 333 abuts against the first end of the first connecting post 331.

[0039] The spring assembly 33, comprising a first connecting post 331, a second connecting post 332, a spring element 333, and a spring limiting member 334, operates as follows: During operation, the spring element 333 is in a pre-compressed state, pushing the first connecting post 331 to move the fixing frame 32 and the mop roller 31 away from the connecting seat 34, thus applying pressure to the fabric. When the mop roller 31 experiences a reaction force from the fabric, for example, when the fabric thickness increases, the first connecting post 331 moves in the direction of spring element 333 contraction, thereby adjusting the pressure of the mop roller 31 on the fabric. This achieves dynamic adjustment of the pressure of the mop roller 31 on the fabric, allowing the fabric to pass smoothly. Furthermore, the second connecting post 332 is inserted into the receiving hole 3312 of the first connecting post 331, forming a sliding guide to prevent lateral displacement of the spring element 333 during compression, ensuring that the mop roller 31 moves in a direction perpendicular to the material surface and improving pressure uniformity.

[0040] Depend on Figure 5 It is known that a connecting post guide hole 343 is provided at the bottom of the receiving groove 341, and the first connecting post 331 is inserted into the receiving groove 341 through the connecting post guide hole 343. By providing the connecting post guide hole 343, the movement of the first connecting post 331 can be guided, reducing the shaking of the first connecting post 331 during movement and ensuring the stability of the pressure provided by the mop roller 31 to the fabric.

[0041] In this embodiment, see Figure 8 The mop wheel device 3 also includes a cam 35 and a limiting block 36. The cam 35 is rotatably mounted on the connecting seat 34. The limiting block 36 is mounted on the first connecting column 331, and the cam 35 cooperates with the limiting block 36. The cam 35 has a first rotation position and a second rotation position. When the cam 35 rotates from the first rotation position to the second rotation position, the cam 35 controls the first connecting column 331 to move in the direction of extending into the spring mounting groove 3341, thereby lifting the mop wheel 31. When the cam 35 rotates from the second rotation position to the first rotation position, the cam 35 controls the first connecting column 331 to move in the direction of exiting the spring mounting groove 3341, thereby lowering the mop wheel 31. By setting the cam 35 and the limiting block 36 to cooperate, when it is necessary to change the fabric, the cam 35 can be controlled to rotate, thereby lifting the mop wheel 31 and providing sufficient space for fabric change. After changing the fabric, the cam 35 can be controlled to rotate, lowering the mop wheel 31, thereby cooperating with the roller 4 to press the fabric.

[0042] In this embodiment, the cam 35 is mounted on the connecting seat 34 via the handle assembly 37, and the handle assembly 37 drives the cam 35 to rotate. By setting the handle assembly 37 to control the rotation of the cam 35, it is convenient to manually control the mop wheel 31.

[0043] See Figure 9The handle assembly 37 includes a handle part 371, a rotating shaft 372, and a damping element 373. The handle part 371 is connected to the first end of the rotating shaft 372 through a through hole 3711, and the second end of the rotating shaft 372 is connected to a cam 35 through a through hole 351. The damping element 373 is fitted onto the rotating shaft 372. Figure 5 It is known that the connecting seat 34 is provided with a handle mounting hole 344, and the rotating shaft 372 is inserted into the handle mounting hole 344 through the damping element 373. The handle assembly 37, by providing the rotating shaft 372 and the damping element 373, with the rotating shaft 372 inserted into the handle mounting hole 344 through the damping element 373, can use the resistance of the damping element 373 to fix the cam 35 in the required position.

[0044] As described above, the mop roller device 3 of this utility model mounts the mop roller 31 by setting a spring assembly 33, allowing the mop roller 31 to move along the extension and retraction direction of the spring assembly 33. Under the pressure of the spring assembly 33, the mop roller 31 is pressed tightly against the material surface and rotates with the fabric feeding direction, driving the material forward at a uniform speed through friction. When the material thickness is uneven, the height of the mop roller 31 is automatically adjusted by the extension and retraction of the spring, which can realize dynamic adjustment of the pressure of the mop roller 31 on the fabric, reduce rigid compression on the fabric, avoid jamming or damage to the fabric, and ensure the uniformity of processing.

[0045] It should be noted that the above are only preferred embodiments of the present utility model, but the design concept of the utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall also fall within the protection scope of the present utility model.
