Description

Technical Field

[0001] This utility model relates to the field of fabric equipment operation protection technology, and more specifically, to a fabric equipment main unit protection device. Background Technology

[0002] Fabric weaving equipment typically includes a main machine, a tensioning and transmission structure, and a winding machine. The main machine is the core equipment in the weaving process, responsible for weaving warp and weft threads into fabric. The tensioning and transmission structure mainly ensures that the fabric maintains appropriate tension during transportation. The winding machine is mainly used to wind up the woven fabric for subsequent processing and transportation.

[0003] During the weaving process, the main machine uses multiple shuttles to weave the warp and weft threads into fabric. Then, the woven fabric is transferred to the winding machine through a tensioning and transmission structure, and the winding machine generates traction tension to wind the fabric into tubes.

[0004] However, if the winding machine malfunctions and stops working, the fabric between the main machine and the winding machine will loosen. This will cause the warp threads on the main machine to lose traction and fall. At this time, the shuttle, which is still running, will knock off some or all of the warp threads, eventually leading to damage to the main machine components. Utility Model Content

[0005] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a main unit protection device for fabric processing equipment, designed to prevent damage to the main unit components when the winding machine malfunctions.

[0006] According to an embodiment of the present invention, a protective device for a main fabric equipment includes a main unit, a tensioning and transmission structure, and a winding machine. The protective device for the main fabric equipment includes a clamping mechanism, a sensor, a driving mechanism, and a control unit. The clamping mechanism includes clamping arms and a driving assembly arranged opposite each other. The two clamping arms are respectively disposed above and below the fabric being transmitted. Each clamping arm has a clamping plane. The driving assembly is convectively connected to the clamping arms and is used to drive the two clamping arms away from each other and to drive the two clamping arms closer to each other until the two clamping planes clamp the fabric being transmitted. The sensor is used to emit a trigger signal when the fabric being transmitted by the tensioning and transmission structure droops. The driving mechanism is disposed on the tensioning and transmission structure and is convectively connected to the clamping mechanism. It is used to drive the clamping mechanism to move along the transmission direction of the fabric until the fabric being transmitted is tensioned. The control unit is used to control the main unit, the sensor, and the driving mechanism to perform corresponding actions according to a preset process when the trigger signal is detected.

[0007] According to some embodiments of this utility model, the clamping arm is provided with a row of teeth, and the driving assembly includes a slide, two sets of gears, a push rod, a transmission structure, and a driver. The slide is located on one side of the fabric being transported, the clamping arm is slidably mounted on the slide, both sets of gears are rotatably mounted on the slide, and the two gears are respectively meshed with the two rows of teeth. The push rod is horizontally slidably mounted on the slide, and the two sets of gears are respectively located on both sides of the push rod's movement path. The transmission structure is used to drive the push rod and the gears to rotate as the push rod moves horizontally. The driver is poweredly connected to the push rod to drive the push rod to move horizontally.

[0008] According to some embodiments of the present invention, the transmission structure includes a fixed arm and a rotating arm. The fixed arm is located at one end of the push rod near the clamping arm, and the two ends of the rotating arm are rotatably connected to the gear and the fixed arm, respectively.

[0009] According to some embodiments of the present invention, the driving mechanism includes a linear motor, and the slide on the linear motor is connected to the slide block.

[0010] According to some embodiments of the present invention, a tension detector is provided on the clamping arm, and the tension detector is electrically connected to the control unit.

[0011] According to some embodiments of the present invention, the sensor is selected from ultrasonic sensors, and the ultrasonic sensors are disposed on the clamping arm.

[0012] According to some embodiments of the present invention, the sensor is selected from a capacitive proximity switch, which is disposed on the clamping arm located below the conveyed fabric.

[0013] According to some embodiments of the present invention, a mounting cavity is provided on the clamping plane of the clamping arm located below the conveyed fabric, the capacitive proximity switch is disposed in the mounting cavity, and the detection end of the capacitive proximity switch is flush with the clamping plane.

[0014] According to some embodiments of the present invention, a buffer spring is provided between the slide and the rail on the linear motor.

[0015] According to some embodiments of the present invention, rubber protrusions are arranged in an array on the clamping plane.

[0016] The fabric equipment main unit protection device according to the embodiment of this utility model has at least the following beneficial effects: by driving the action of the clamping mechanism in coordination with the drive mechanism, when the control unit receives the trigger signal sent by the sensor, the control unit controls the main unit to stop the machine, and at the same time controls the two clamping arms of the clamping mechanism to move closer to each other until the conveyed fabric is clamped.

[0027] Reference Figures 1 to 4 The diagram illustrates a protective device for the main unit of a fabric processing equipment disclosed in this utility model. The fabric processing equipment includes a main unit 100, a tensioning transmission structure 200, and a winding machine 300. The main unit 100 is used to weave warp and weft threads into fabric. The tensioning transmission structure 200 is used to transmit the woven fabric and maintain appropriate tension during transportation. The winding machine 300 is used to wind up the woven fabric transmitted by the tensioning transmission structure 200 for subsequent processing and transportation. The protective device for the main unit of the fabric processing equipment includes a clamping mechanism 400, a sensor 500, a drive mechanism 600, and a control unit (not shown in the diagram).

[0028] Specifically, the clamping mechanism 400 includes clamping arms 410 and a drive assembly 420 disposed opposite to each other. The two clamping arms 410 are respectively positioned above and below the fabric being transported. Each clamping arm 410 has a clamping surface 411, which are vertically opposite to each other. The fabric being transported passes through the space between the two clamping surfaces 411. The drive assembly 420 is driveably connected to the clamping arms 410 and is used to drive the two clamping arms 410 away from each other and to drive them closer together until the two clamping surfaces 411 clamp the fabric being transported. The sensor 500 is used to issue a trigger signal when the fabric being transported by the tensioning transmission structure 200 droops. The drive mechanism 600 is disposed on the tensioning transmission structure 200 and is driveably connected to the clamping mechanism 400. When the control unit receives a trigger signal from the sensor 500, it stops the main unit 100 and simultaneously moves the two clamping arms 410 of the clamping mechanism 400 closer together until they clamp the fabric being transported. Then, it controls the drive mechanism 600 to move the clamping mechanism 400 along the fabric transport direction until the fabric is re-tensioned. This prevents the warp threads on the main unit 100 from falling due to loss of traction, which could cause the shuttle to knock off some or all of the warp threads, damaging components of the main unit 100. Optionally, the control unit can be an electronic control module such as a microcontroller, PLC, DSP, or FPGA.

[0029] In some embodiments of this utility model, such as Figure 3 As shown, the clamping arm 410 is provided with a toothed rack 411, and the drive assembly 420 includes a slide 421, two sets of gears 422, a push rod 423, a transmission structure 424, and a driver 425. The slide 421 is located on one side of the fabric being transported, and the clamping arm 410 is slidably mounted on the slide 421. Both sets of gears 422 are rotatably mounted on the slide 421, and the two gears 422 are respectively meshed with the two toothed racks 411. Thus, when the gears 422 rotate, the toothed racks 411 slide up and down on the slide 421, causing the two clamping arms 410 to move closer to or further away from each other. The push rod 423 is horizontally slidably mounted on the slide block 421. Two sets of gears 422 are respectively arranged on both sides of the moving path of the push rod 423. The transmission structure 424 drives the push rod 423 and the gears 422. The driver 425 is poweredly connected to the push rod 423, so that when the driver 425 drives the push rod 423 to move horizontally, it drives the gears 422 to rotate, thereby pushing the two clamping arms 410 closer to each other or further apart. Optionally, the driver 425 can be a telescopic motor, a telescopic cylinder, a telescopic hydraulic cylinder, etc. Preferably, in order to improve the speed at which the two clamping arms 410 clamp the fabric, the driver 425 is preferably a telescopic cylinder.

[0030] In some embodiments of this utility model, such as Figure 3As shown, the transmission structure 424 includes a fixed arm 4241 and a rotating arm 4242. The fixed arm 4241 is located at one end of the push rod 423 near the clamping arm 410. The two ends of the rotating arm 4242 are rotatably connected to the gear 422 and the fixed arm 4241, respectively. When the push rod 423 slides horizontally on the slide block 421, the fixed arm 4241 drives the rotating arm 4242 to rotate. The rotation of the rotating arm 4242 drives the gear 422 to rotate. The rotation of the gear 422 drives the gear rack 411 to slide on the slide block 421.

[0031] In some embodiments of this utility model, such as Figure 2 As shown, the drive mechanism 600 includes a linear motor, and a slide 610 on the linear motor is connected to a slide block 421. When the slide 610 slides, it drives the slide block 421 to move along the fabric transmission direction, so that the fabric that is falling between the host 100 and the tensioning transmission structure 200 is re-tensioned.

[0032] To prevent the fabric falling between the main unit 100 and the tensioning transmission structure 200 from being stretched too tightly when the slide 421 moves along the fabric transport direction, thus preventing the fabric from being pulled apart, in some embodiments of this utility model, such as... Figure 4 As shown, a tension detector 412 is provided on the clamping arm 410, and the tension detector 412 is electrically connected to the control unit. During the actual test, the measuring head of the tension detector 412 is perpendicular to the surface of the fabric, and then a certain pressure is applied to the fabric by the measuring head until the measurement requirements are met. The control unit acquires the tension value collected by the tension detector 412 in real time. When the tension value exceeds a certain value, the control unit controls the drive mechanism 600 to stop moving to prevent the fabric from being pulled apart.

[0033] In some embodiments of this utility model, the sensor 500 is selected from an ultrasonic sensor. The ultrasonic sensor is mounted on the clamp arm 410, and the sound waves emitted by the ultrasonic sensor are used to determine whether the fabric is sagging.

[0034] In some embodiments of this utility model, such as Figure 4 As shown, sensor 500 is selected from capacitive proximity switches. Specifically, the capacitive proximity switch is disposed on clamping arm 410 located below the conveyed fabric. When the falling fabric touches the capacitive proximity switch on clamping arm 410, it indicates that the fabric has drooped.

[0035] In some embodiments of this utility model, such as Figure 4As shown, a mounting cavity 413 is provided on the clamping plane 411 of the clamping arm 410 located below the conveyed fabric. A capacitive proximity switch is installed in the mounting cavity 413, and the detection end of the capacitive proximity switch is flush with the clamping plane. This is to prevent the capacitive proximity switch from being damaged when the upper and lower clamping arms 410 clamp the fabric. At the same time, the capacitive proximity switch is installed on the clamping arm 410 to determine whether the two clamping arms 410 are separated, so as to avoid affecting the normal transmission of the fabric after the winding machine is repaired.

[0036] Because the slide 421 needs to be moved along the fabric conveying direction in a short time, the slide table 610 moves at a high speed, generating a large impulse, which can easily cause the fabric between the host 100 and the tensioning conveying structure 200 to break. Therefore, in some embodiments of this utility model, such as... Figure 2 As shown, a buffer spring 700 is provided between the slide table 610 on the linear motor and the rail base 620, and the moving speed of the slide table 610 is gradually reduced by the buffer spring 700.

[0037] To prevent the fabric from sliding relative to the clamping plane 411 when the upper and lower clamping arms 410 clamp the fabric, and to prevent damage to the fabric surface caused by clamping, in some embodiments of this utility model, such as... Figure 4 As shown, rubber protrusions 4111 are arranged in an array on the clamping plane 411. By setting the rubber protrusions 4111, on the one hand, the friction between the clamping plane 411 and the fabric can be increased, making it easier to clamp the fabric; on the other hand, since the rubber material is relatively soft, it is not easy to damage the fabric when the rubber comes into contact with the fabric.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
