Description

Technical Field

[0001] This utility model relates to fabric slitting equipment, specifically to a fully automatic ultrasonic fabric strip slitting machine. Background Technology

[0002] When making other products from a whole piece of fabric (such as making masks from non-woven fabric), the whole piece of fabric needs to be cut into strips so that the size of the strips obtained from the cutting meets the requirements for making the corresponding products. A slitting machine is needed when cutting the fabric into strips.

[0003] CN217351915U discloses a fabric strip cutting machine, which includes a machine body, an active roller rotatably mounted on the machine body, a pressure roller rotatably mounted on the machine body, and a driving component for driving the active roller to rotate. The pressure roller presses against the active roller. A plurality of pneumatic cutters for cutting fabric are fixed on the machine body on one side of the active roller. The pneumatic cutters are arranged in an axial direction parallel to the active roller, and the blades of the pneumatic cutters face the active roller.

[0004] In operation, the fabric strip cutting machine described above allows the fabric to pass between the driven roller and the driving roller. Then, a rotary cylinder drives a pressure plate to move a clamping roller away from the driving roller, allowing the fabric to pass between the clamping roller and the driving roller. The rotary cylinder then drives the clamping roller to press against the driving roller. As the driving roller rotates, it conveys the fabric towards the pneumatic cutter. When cutting fabric strips of different widths, the locking bolts can be loosened to adjust the position of the clamping roller along the adjusting groove, allowing it to move closer to or further away from the pneumatic cutter.

[0005] For the aforementioned fabric strip cutting machine, after the fabric is cut into strips, burrs will appear on the cut edges on both sides of the strips. The aforementioned fabric strip cutting machine cannot process these burrs, which will affect the quality of the corresponding products when the strips are used to produce them. Utility Model Content

[0006] This invention provides a fully automatic ultrasonic fabric strip cutting machine, which sewn the cut edges while cutting the fabric.

[0007] The technical solution to the above problem is as follows:

[0008] The fully automatic ultrasonic fabric strip slitting machine includes a frame, a first tensioning roller, a slitting mechanism, a clamping roller mechanism, and a drive mechanism. The first tensioning roller is rotatably mounted on the frame. The slitting mechanism is located on the frame and between the first tensioning roller and the clamping roller mechanism. The clamping roller mechanism is mounted on the frame. The drive mechanism is connected to the clamping roller mechanism. The machine also includes an ultrasonic sewing mechanism for sewing the slitting strips. The ultrasonic sewing mechanism is mounted on the frame and works in conjunction with the slitting mechanism.

[0009] Furthermore, the pinch roller mechanism includes a mounting frame, a first bearing assembly, a second bearing assembly, an upper pinch roller, a lower pinch roller, and a lifting driver. The mounting frame is fixed on the machine frame. The first bearing assembly is slidably engaged with the mounting frame. The second bearing assembly is fixed on the mounting frame. Both ends of the upper pinch roller are connected to the first bearing assembly, and both ends of the lower pinch roller are connected to the second bearing assembly. The lower pinch roller is also connected to the driving mechanism. The lifting driver is mounted on the mounting frame and is connected to the first bearing assembly.

[0010] Furthermore, the ultrasonic suturing mechanism includes a support frame and an ultrasonic welding assembly. The support frame is fixed to the machine frame, the ultrasonic welding assembly is mounted on the support frame, and the ultrasonic welding assembly is clearance-fitted with the slitting mechanism.

[0011] Furthermore, it also includes a feeding mechanism, which includes a base frame, a movable frame, a feeding support, a fabric side detection component, and a correction driver. The movable frame is movably connected to the base frame, the feeding support is fixed on the movable frame, the fabric side detection component is installed on the base frame, and the correction driver is connected to the base frame and the movable frame respectively.

[0012] Furthermore, it also includes a first winding mechanism for winding the odd-numbered strips of fabric and a second winding mechanism for winding the even-numbered strips of fabric. The first winding mechanism and the second winding mechanism are arranged on the frame at different heights, and the first winding mechanism and the second winding mechanism are respectively connected to the drive mechanism.

[0013] Furthermore, both the first and second winding mechanisms include a support, a winding shaft, a driven gear, a driving gear, and a rotating shaft. The support is fixed to the frame, the winding shaft is fitted to the support, the driven gear is fixed to the winding shaft, the driven gear meshes with the driving gear, the driving gear is fixed to the rotating shaft, and the rotating shaft is rotatably mounted on the frame and connected to the drive mechanism.

[0014] When the slitting mechanism cuts the fabric, the ultrasonic sewing mechanism acts as a cutter holder, meaning the fabric slitting mechanism 3 is pressed onto the ultrasonic sewing mechanism to cut it. At the same time, the high-frequency ultrasonic energy output by the ultrasonic sewing mechanism generates low-amplitude mechanical vibration. This vibration is transmitted to the cut edge of the fabric strip, and the thermoplastic fabric melts through frictional heat, thus forming a weld. Therefore, this invention sewn the cut edge while cutting the fabric, ensuring that the sides of the cut fabric strip are free of fraying, thereby guaranteeing the quality of the products produced in subsequent manufacturing processes.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing" and other such terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components, unless otherwise explicitly limited.

[0024] like Figures 1 to 3 As shown, the fully automatic ultrasonic fabric strip slitting machine of this utility model includes a frame 1, a first tensioning roller 2, a slitting mechanism 3, a clamping roller mechanism, and a drive mechanism 4. The following is a detailed description of each part and the relationship between them.

[0025] The first tension roller 2 is rotatably mounted on the frame 1. Its main function is to create tension in the fabric, preventing it from becoming slack and thus avoiding unevenness after being cut into strips. The frame 1 is equipped with a support seat 1a, and both ends of the first tension roller 2 are clearance-fitted into the support seat 1a. A slitting mechanism 3 is mounted on the frame 1, located between the first tension roller 2 and the clamping roller mechanism. The slitting mechanism 3 can employ… Figure 1 The structure shown can also be the structure consisting of a guide rail and a pneumatic cutter as described in CN217351915U.

[0026] The pinch roller mechanism is mounted on the frame 1, and the drive mechanism 4 is connected to the pinch roller mechanism. When the pinch roller mechanism is working, it generates a pinching force on the fabric, causing the fabric to move. The pinch roller mechanism includes a mounting frame 5, a first bearing assembly 6, a second bearing assembly 7, an upper pinch roller 8, a lower pinch roller 9, and a lifting driver 10. The mounting frame 5 is fixed on the frame 1. The first bearing assembly 6 is slidably engaged with the mounting frame 5. The second bearing assembly 7 is fixed on the mounting frame 5. The two ends of the upper pinch roller 8 are respectively connected to the first bearing assembly 6, and the two ends of the lower pinch roller 9 are respectively connected to the second bearing assembly 7. The lower pinch roller 9 is also connected to the drive mechanism 4. The lifting driver 10 is mounted on the mounting frame 5 and is connected to the first bearing assembly 6. The lifting driver 10 can be a linear drive component such as a cylinder or a hydraulic cylinder.

[0027] Since different fabrics may have different thicknesses, the lifting drive 10 drives the first bearing assembly 6 to rise or fall, thereby adjusting the distance between the upper clamping roller 8 and the lower clamping roller 9. Furthermore, since the fabric is cut into strips by the slitting mechanism 3, and the strips pass between the upper clamping roller 8 and the lower clamping roller 9, adjusting the distance between the upper and lower clamping rollers changes the angle between the fabric and the upper clamping roller 8, thus adjusting the pressure exerted by the slitting mechanism 3 on the fabric. For example, for thicker fabrics, the lifting drive 10 drives the first bearing assembly 6 to rise, increasing the slope of the fabric passing through the slitting mechanism 3 and the upper clamping roller 8. Since the position of the slitting mechanism 3 remains unchanged, the pressure exerted by the slitting mechanism 3 on the fabric increases, making it easier for the slitting mechanism 3 to cut the fabric.

[0028] An ultrasonic sewing mechanism sews the cut fabric strips together. The ultrasonic sewing mechanism is mounted on frame 1 and works in conjunction with the cutting mechanism 3. When the cutting mechanism 3 cuts the fabric, the ultrasonic sewing mechanism acts as a cutter, pressing the fabric cutting mechanism 3 against it and cutting it. Simultaneously, the high-frequency ultrasonic energy output by the ultrasonic sewing mechanism generates low-amplitude mechanical vibrations. These vibrations are transmitted to the cut edges of the fabric strips, generating heat through friction and melting the thermoplastic fabric to form a weld. Therefore, this invention sews the cut edges simultaneously with the fabric cutting, ensuring that the sides of the cut fabric strips are free of fraying, thus guaranteeing the quality of the products produced using the fabric strips in subsequent manufacturing.

[0029] The ultrasonic suturing mechanism includes a support 11 and an ultrasonic welding assembly 12. The support 11 is fixed to the frame 1, the ultrasonic welding assembly 12 is mounted on the support 11, and the ultrasonic welding assembly 12 is clearance-fitted with the cutting mechanism 3.

[0030] This utility model also includes a feeding mechanism, which includes a base frame 13, a movable frame 14, a feeding support 15, a fabric side detection component 16, and a correction driver 17. The movable frame 14 is movably connected to the base frame 13. A guide component is provided on the base frame 13, and a guide sleeve is provided at the bottom of the movable frame 14. The guide sleeve slides with the guide component on the base frame 13, thereby movably connecting the movable frame 14 and the base frame 13. The feeding support 15 is fixed on the movable frame 14. The fabric side detection component 16 is installed on the base frame 13. The fabric side detection component 16 preferably adopts a photoelectric sensor. The correction driver 17 is connected to the base frame 13 and the movable frame 14 respectively. The correction driver 17 can be a cylinder or a hydraulic cylinder.

[0031] The feeding roller C, which is wound with fabric, is engaged with the feeding support 15. After the fabric is released from the feeding roller C, it passes through the fabric side detection component 16. The fabric side detection component 16 detects whether the fabric is off-center. If it is off-center, the correction driver 17 is activated. The correction driver 17 drives the movable frame 14 to move on the base frame 13, adjusts the position of the feeding roller C, and thus adjusts the arrangement of the fabric.

[0032] The fully automatic ultrasonic fabric strip slitting machine of this utility model also includes a first winding mechanism A for winding the odd-numbered fabric strips and a second winding mechanism B for winding the even-numbered fabric strips. The first winding mechanism A and the second winding mechanism B are arranged on the frame 1 at different heights. The first winding mechanism A and the second winding mechanism B are respectively connected to the drive mechanism 4. For example, after the fabric is slitted by the slitting mechanism 3, the number of fabric strips obtained is 10. These 10 fabric strips are arranged sequentially from the first direction to the second direction (e.g., from left to right). Among them, the 1st, 3rd, 5th, 7th and 9th strips are wound by the first winding mechanism A, and the 2nd, 4th, 6th, 8th and 10th strips are wound by the second winding mechanism B.

[0033] Both the first winding mechanism A and the second winding mechanism B include a support 18, a winding shaft 19, a driven gear 20, a driving gear 21, and a rotating shaft 22. The support 18 is fixed to the frame 1, the winding shaft 19 cooperates with the support 18, the driven gear 20 is fixed to the winding shaft 19, the driven gear 20 meshes with the driving gear 21, the driving gear 21 is fixed to the rotating shaft 22, and the rotating shaft 22 is rotatably mounted on the frame 1 and connected to the drive mechanism 4.

[0034] The drive mechanism 4 consists of a motor 4a, a first belt drive mechanism 4b, a second belt drive mechanism 4c, an intermediate transmission assembly 4d, a third belt drive mechanism 4e, a fourth belt drive mechanism 4f, and a fifth belt drive mechanism 4g. The first belt drive mechanism 4b is connected to both the motor 4a and the lower clamping roller 9. The second belt drive mechanism 4c is connected to both the motor 4a and the intermediate transmission assembly 4d. The third belt drive mechanism 4e is connected to the intermediate transmission assembly 4d, the fourth belt drive mechanism 4f, and the fifth belt drive mechanism 4g. The fourth belt drive mechanism 4f is connected to the first winding mechanism A, and the fifth belt drive mechanism 4g is connected to the second winding mechanism B. This structure uses only one motor 4a and multiple belt drive mechanisms to complete the transmission of multiple parts, which has the advantage of cost saving.
