Description

Technical Field

[0001] This utility model relates to the field of drawing frame equipment technology, and in particular to an automatic sliver breaking device for a drawing frame. Background Technology

[0002] The drawing frame is a key piece of equipment in the spinning process, connecting carding and roving. Through functions such as doubling, drafting, mixing, and sliver formation, it processes multiple fiber slivers into a high-quality sliver with a uniform structure. Sometimes, for necessary operations such as process control, quality assurance, and equipment maintenance, it is necessary to actively break the sliver. For example, after changing roller spacing or adjusting draft ratio, the currently running sliver needs to be cut and re-started to verify the evenness and fiber straightening effect under the new process.

[0003] Currently, when workers need to actively break cotton slivers on a drawing frame, they usually stop the drawing frame first and then manually break or cut the cotton sliver. However, sometimes the cotton sliver is quite tough and not easy to break, and using tools to cut the cotton sliver is problematic because some tools are not easy to insert, and using tools can easily damage the drawing frame. If some parts of the drawing frame are damaged, it will cause significant losses.

[0004] In addition, drawing frames usually feed in multiple slivers at the same time, so it is time-consuming and laborious for workers to break the slivers one by one. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose an automatic sliver breaking device for drawing sliver machines, so as to solve the technical problem that manual operation by workers is troublesome and difficult when it is necessary to actively break the sliver in the prior art.

[0006] To achieve the above objectives, this utility model provides an automatic sliver breakage device for a drawing frame, comprising a front guide wheel and a rear guide wheel for guiding the sliver thread, wherein the front guide wheel and the rear guide wheel are connected to a support via a crossbeam, and the automatic breakage device further includes:

[0007] The dispensing wheel is movably connected to the bracket. The dispensing wheel is located between the front guide wheel and the rear guide wheel, and the cotton strip passes through the lower end of the dispensing wheel. Slider blocks are also connected to both sides of the bearing of the dispensing wheel.

[0008] A lifting motor is fixedly installed on the top of the bracket. A sling drum is connected to the output shaft of the lifting motor. A sling is connected to and wound on the sling drum. The lower end of the sling is fixedly connected to the slider.

[0009] Furthermore, the cotton swab passes over the front and rear guide wheels, and the crossbeam is located above the dispensing wheel and below the lifting motor.

[0010] Furthermore, the front guide wheel and the rear guide wheel are rotatably connected to the front and rear ends of the crossbeam, and the crossbeam is fixedly connected to the bracket.

[0011] Furthermore, the bracket has grooves on both sides, the slider is slidably connected in the grooves, and the bearing of the adjusting wheel is rotatably connected to the slider.

[0012] Furthermore, a connecting box is provided below the lifting motor, the connecting box is fixedly connected to the bracket, and the sling drum is rotatably connected inside the connecting box.

[0013] Furthermore, the bottom left and right sides of the connecting box are provided with a through hole, and each through hole is also provided with a pulley. The slings on both sides of the adjusting wheel pass through the two through holes and are connected to the pulleys.

[0014] Furthermore, a check chamber is fixedly connected to the crossbeam, and a check mechanism is provided inside the check chamber to prevent the front guide wheel from rotating.

[0015] Furthermore, the anti-return mechanism includes a rotating gear fixedly connected to the shaft of the front guide wheel. The rotating gear is rotatably connected to the outer wall of the crossbeam, and a pawl is rotatably connected to the outer wall of the crossbeam, the pawl meshing with the rotating gear.

[0016] The beneficial effects of this utility model are as follows: 1. A front guide wheel, a rear guide wheel, and an adjusting wheel are provided to guide the sliver thread. The adjusting wheel is movably connected to the bracket and can move up and down. The up and down movement of the adjusting wheel is driven and controlled by a lifting motor. Therefore, the up and down position of the adjusting wheel can be adjusted by the lifting motor, thereby adjusting the tension of the sliver.

[0017] 2. The mixing wheel is made of metal and is heavy enough to break the cotton strip. When it is necessary to break the cotton strip, simply control the lifting motor to fully release the mixing wheel. The mixing wheel will fall under its own weight and break the cotton strip located at the bottom of the mixing wheel. The whole process does not require manual operation by workers and is simple, convenient and quick to respond.

[0018] 3. A check mechanism is installed on the front guide wheel to prevent it from rotating back. A check mechanism can also be installed on the rear guide wheel. This prevents the cotton sliver from rotating back along with the front and rear guide wheels when the dispensing wheel drops and breaks the sliver, thus facilitating the breakage of the sliver.

[0019] 4. The lifting motor controls the up-and-down movement of the adjusting wheel via a sling. The lifting motor is a servo motor, capable of precisely controlling the displacement of the adjusting wheel, thus accurately adjusting the tension of the swab. Simply de-energizing the lifting motor allows its output shaft to rotate freely, enabling the adjusting wheel to fall freely and break the swab. Furthermore, the sling length is pre-set so that even when the sling is at its maximum length, the adjusting wheel (and its corresponding slider) remains suspended, preventing it from hitting other components.

[0029] The first aspect of this utility model is as follows: Figure 1 , Figure 2 and Figure 3 As shown, sometimes it is necessary to actively break the cotton sliver 01 for process control, quality assurance, and equipment maintenance, but manual operation by workers is troublesome and difficult. Therefore, this utility model designs a front guide wheel 103 and a rear guide wheel 104 to guide the cotton sliver 01. The front guide wheel 103 and the rear guide wheel 104 are connected to the bracket 101 through a crossbeam 102.

[0030] Additionally, a dispensing wheel 106 is movably connected to the bracket 101. The dispensing wheel 106 is located between the front guide wheel 103 and the rear guide wheel 104, and the cotton swab 01 passes under the dispensing wheel 106. Slider blocks 110 are also connected to both sides of the bearing of the dispensing wheel 106. A lifting motor 107 is fixedly connected to the top of the bracket 101. A sling drum 112 is connected to the output shaft of the lifting motor 107. A sling 109 is connected to and wound on the sling drum 112, and the lower end of the sling 109 is fixedly connected to the slider 110.

[0031] The tampons 01 pass over the front guide wheel 103 and the rear guide wheel 104. The crossbeam 102 is located above the dispensing wheel 106 and below the lifting motor 107. The front guide wheel 103 and the rear guide wheel 104 are rotatably connected to the front and rear ends of the crossbeam 102, and the crossbeam 102 is fixedly connected to the bracket 101.

[0032] The dispensing wheel 106 is made of metal and is heavy enough to break the cotton strip 01. When it is necessary to break the cotton strip 01, simply control the lifting motor 107 to fully release the dispensing wheel 106. The dispensing wheel 106 falls under its own weight and can then break the cotton strip 01 located at the lower end of the dispensing wheel 106. The whole process does not require manual operation by workers and is simple, convenient and quick to respond.

[0033] Additionally, a check chamber 113 is fixedly connected to the crossbeam 102. The check chamber 113 is equipped with a check mechanism to prevent the front guide wheel 103 from rotating. The check mechanism includes a rotating gear 114 fixedly connected to the shaft of the front guide wheel 103. The rotating gear 114 is rotatably connected to the outer wall of the crossbeam 102, and a pawl 115 is rotatably connected to the outer wall of the crossbeam 102. The pawl 115 meshes with the rotating gear 114.

[0034] A check mechanism is provided on the front guide wheel 103 to prevent it from rotating. A check mechanism can also be provided on the rear guide wheel 104. When the adjusting wheel 106 falls and breaks the cotton sliver 01, the cotton sliver 01 is prevented from rotating with the front guide wheel 103 and the rear guide wheel 104, so that the cotton sliver 01 can be easily broken.

[0035] The second aspect of this utility model is as follows: Figure 1 , Figure 2 and Figure 4 As shown, this embodiment is an improvement on the original tampon 01 tension adjustment mechanism. The tampon 01 tension adjustment is achieved by setting the tampon 01 to pass over the front guide wheel 103 and the rear guide wheel 104, and the tampon 01 to pass under the distribution wheel 106. The crossbeam 102 is located above the distribution wheel 106 and below the lifting motor 107.

[0036] The front guide wheel 103 and the rear guide wheel 104 are rotatably connected to the front and rear ends of the crossbeam 102, which is fixedly connected to the bracket 101. A sling drum 112 is connected to the output shaft of the lifting motor 107, and a sling 109 is connected to and wound on the sling drum 112. The lower end of the sling 109 is fixedly connected to the slider 110.

[0037] A front guide wheel 103, a rear guide wheel 104, and a distribution wheel 106 are provided to guide the sliver 01. The distribution wheel 106 is movably connected to the bracket 101 and can move up and down. The up and down movement of the distribution wheel 106 is driven and controlled by a lifting motor 107. Therefore, a connecting box 111 is provided below the lifting motor 107. The connecting box 111 is fixedly connected to the bracket 101, and the sling drum 112 is rotatably connected inside the connecting box 111.

[0038] Additionally, a connecting box 111 is provided below the lifting motor 107. The connecting box 111 is fixedly connected to the bracket 101, and the sling drum 112 is rotatably connected inside the connecting box 111. A through hole is provided on each of the left and right sides of the bottom of the connecting box 111, and a pulley is also provided at each through hole. The slings 109 on both sides of the adjusting wheel 106 pass through the two through holes and are connected to the pulleys.

[0039] The lifting motor 107 controls the up-and-down movement of the adjusting wheel 106 via the suspension cable 109. The lifting motor 107 is a servo motor, capable of precisely controlling the displacement of the adjusting wheel 106, thus accurately adjusting the tension of the cotton swab 01. Simply de-energizing the lifting motor 107 allows its output shaft to rotate freely, enabling the adjusting wheel 106 to fall freely and break the cotton swab 01. Furthermore, the length of the suspension cable 109 is pre-set so that even when the cable is at its maximum length, the adjusting wheel 106 (and the corresponding slider 110) remains suspended, preventing it from hitting other components.

[0040] In summary, the dispensing wheel 106 of this invention is made of metal and is heavy enough to break the cotton swab 01. When it is necessary to break the cotton swab 01, simply control the lifting motor 107 to fully release the dispensing wheel 106. The dispensing wheel 106 falls under its own weight, thus breaking the cotton swab 01 located at its lower end. The entire process requires no manual operation and is simple, convenient, and quick to respond. Furthermore, a check mechanism is provided on the front guide wheel 103 to prevent it from rotating back, and a check mechanism can also be provided on the rear guide wheel 104. When the dispensing wheel 106 falls and breaks the cotton swab 01, it prevents the cotton swab 01 from causing the front guide wheel 103 and the rear guide wheel 104 to rotate back, facilitating the breaking of the cotton swab 01.

[0041] Furthermore, a front guide wheel 103, a rear guide wheel 104, and a distribution wheel 106 are configured to guide the sliver 01. The distribution wheel 106 is movably connected to the bracket 101 and can move up and down. The up and down movement of the distribution wheel 106 is driven and controlled by a lifting motor 107. Therefore, the up and down position of the distribution wheel 106 can be adjusted by the lifting motor 107, thereby adjusting the tension of the sliver 01. The lifting motor 107 controls the up and down movement of the distribution wheel 106 via a suspension cable 109. The lifting motor 107 is a servo motor, which can precisely measure the displacement of the distribution wheel 106, thereby accurately adjusting the tension of the sliver 01. The lifting motor 107 only needs to be de-energized, allowing its output shaft to rotate freely, so that the distribution wheel 106 can fall freely and break the sliver 01. The length of the suspension cable 109 is pre-set so that when the suspension cable 109 is stretched to its maximum length, the distribution wheel 106 remains suspended, preventing it from hitting other components.
