Description

Technical Field

[0001] The present application relates to the field of textile machinery, and more specifically, to a drawing frame breaking device. Background Art

[0002] The drawing frame is a spinning machine that mixes several carded or combed fiber strips into fiber strips with certain quality requirements. The function of the drawing frame is to improve the internal structure of the slivers, thereby improving the uniformity of its long segments, while reducing the weight unevenness, making the fibers in the slivers straight and parallel, reducing hooks, making the fineness meet the requirements, and making the raw materials of different types or qualities mix evenly to achieve the specified mixing ratio. After the slivers are processed in the drawing frame, the subsequent slivers need to be cut.

[0003] The patent with application number 202221376817.5 discloses a sliver-breaking device for a drawing frame, which solves the problem that the sliver-breaking device for drawing frames on the market in the prior art inevitably produces cotton wool due to cutting when breaking the slivers. Under the influence of gravity, the cotton wool will naturally fall to the bottom of the device, which is time-consuming and laborious for personnel to clean manually, causing great inconvenience to the staff and reducing the efficiency of the device. A sliver-breaking device for a drawing frame includes a shell, a top cover is fixedly connected to the upper surface of the shell, and a hydraulic cylinder is installed at the center of the top of the inner cavity of the top cover, and a blade is fixedly connected to the bottom of the hydraulic cylinder. This application avoids the situation where personnel need to manually clean the cotton wool that has fallen off at the bottom of the inner cavity of the shell, and while ensuring the safety of personnel, the cleaning can be carried out without stopping the operation of the device, thereby increasing the continuous working efficiency of the device and improving the utilization rate of the device.

[0004] With regard to the above-mentioned related technologies, the blade is driven downward by a hydraulic cylinder to cut off the sliver through contact with the sliver. Due to the influence of gravity, cotton wool on the surface of the sliver will inevitably fall off to the bottom of the inner cavity of the shell during the cutting process or the transmission process. The brush plate is driven by the cylinder and the piston rod to make the brush plate clean the bottom of the inner cavity of the shell, and the cotton wool at the bottom of the inner cavity of the shell is uniformly cleaned to the through groove. However, the cut sliver is not fixed and may slide out of the shell under the action of its own gravity, causing some cotton wool to fall to the ground, resulting in material waste, and the sliver may be contaminated by ground dust. Utility Model Content

[0005] In order to solve the above problems, the present application provides a drawing frame breaking device, which adopts the following technical solution:

[0006] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0007] By adopting the above technical scheme, when the equipment is used, the staff inserts the slivers into the box through one of the inlets and outlets opened on the side wall of the box, and makes the slivers pass through the rotating rod and the support rod in turn, and then makes the slivers be discharged through the other inlet and outlet into the drawing machine for operation. The side walls of the rotating rod and the support rod are respectively provided with a first guide wheel and a second guide wheel. The first guide wheel and the second guide wheel can limit the slivers, which is beneficial to maintain the stability of the sliver transportation, and play a role in separating the slivers, which helps to avoid the entanglement of the slivers during transportation. The inlet and outlet are provided with support rollers to support the slivers, and help to avoid wear of the slivers during transportation. The two rotating rods are connected. The tension adjusting component is set to adjust the tension of the sliver during transportation, which helps to avoid loosening of the sliver during transportation. When the sliver needs to be cut, the sliver is pressed by the pressing component to position and fix the sliver. Subsequently, the reciprocating screw is driven to rotate by the driving component, and the reciprocating screw drives the support block to move synchronously with the cutting component, thereby cutting the sliver. The sliver is fixed by the pressing component and will not slide out of the box through the inlet and outlet, which helps to avoid the cotton wool floating to the outside. Some of the cotton wool at the broken end of the sliver falls into the collection frame slidably installed at the bottom of the box. Subsequently, the staff can pull the collection frame to make the collection frame slide out of the box, which is convenient for the staff to clean the cotton wool later.

[0008] Furthermore, the tension adjustment assembly includes mounting blocks rotatably mounted on both ends of the rotating rod, a cylinder is fixedly mounted on the top of the box body, and a connecting plate is fixedly mounted on the end of the cylinder piston shaft, connecting frames are fixedly mounted on both ends of the connecting plate, and the bottom ends of the two connecting frames are slidably penetrated into the box body, support plates are fixedly mounted on the bottom ends of the two connecting frames, and two symmetrically distributed pillars are fixedly mounted on the bottom ends of the two support plates, movable grooves are opened at the bottom ends of the pillars, and support rods are slidably mounted in the movable grooves, a spring is fixedly connected between the top end of the support rod and the inner wall of the top end of the movable groove in the same group, and the bottom end of the support rod is fixedly connected to the top end of the mounting block in the same group.

[0009] By adopting the above technical scheme, when the sliver passes through the side wall of the rotating rod, the rotating rod plays the role of supporting the sliver, which is convenient for the transportation of the sliver, and the support rod pushes the mounting block of the same group to move downward synchronously with the rotating rod under the action of the elastic force of the same group of springs. Through the cooperation of the spring and the support rod, the support rod slides up and down in the movable groove, which plays the role of adjusting the tension during the transportation of the sliver. When the sliver is still somewhat loose, the connecting plate can be driven by the cylinder to move down with the connecting frame, so that the connecting frame moves down with the support plate of the same group, and the support plate pushes the pillar, spring and support rod of the same group to move downward synchronously. The support rod pushes the mounting block and the rotating rod to move downward synchronously, thereby playing the role of further adjusting the tension during the transportation of the sliver, which is convenient for the stable transportation of the sliver.

[0010] Furthermore, two symmetrically distributed limit blocks are fixedly mounted on the side walls at the top ends of the support rods, and the inner walls of the movable grooves are provided with limit grooves matching the limit blocks in the same group.

[0011] By adopting the above technical solution, when the support rod slides in the movable groove, the support rod slides in the limit groove with the limit block. The cooperation between the limit block and the limit groove helps to prevent the support rod from leaving the movable groove and helps to maintain the stability of the sliding of the support rod.

[0012] Furthermore, a sliding block is fixedly mounted on one side of the mounting block away from the rotating rods in the same group, and a sliding groove matching the sliding block on the same side is formed on the inner wall of the box body.

[0013] By adopting the above technical solution, when the mounting block slides in the box, the mounting block slides with the slider in the same side slide groove. The cooperation of the slider and the slide groove is conducive to maintaining the stability of the mounting block and the rotating rod when lifting and lowering.

[0014] Furthermore, the pressing assembly includes a mounting plate arranged above the two support rods, and two groups of symmetrically distributed first telescopic rods are fixedly installed on the inner wall of the top end of the box body. There are two first telescopic rods in the same group and they are symmetrically distributed on the inner wall of the top end of the box body. The ends of the two first telescopic rods in the same group are fixedly connected to the top of the mounting plate on the same side, and rubber pads are fixedly installed on the bottom ends of the two mounting plates.

[0015] By adopting the above technical scheme, when it is necessary to cut the tampon, the first telescopic rod is used to drive the mounting plate and the rubber pad of the same group to move downward, so that the rubber pad contacts the second guide wheel of the same group. Subsequently, the rubber pad continues to move downward under the driving force of the first telescopic rod of the same group, so that the rubber pad is deformed, and then the rubber pad is engaged with the second guide wheel of the same group, which can press and fix the tampon, making it convenient for the equipment to cut the tampon later. After the cutting of the tampon is completed, the tampon will not be pulled out of the box due to its own gravity because it is pressed and fixed by the rubber pad, so that the cotton wool from the broken end of the tampon can fall stably into the collection frame, making it convenient for the staff to collect it later.

[0016] Furthermore, the cutting assembly includes a second telescopic rod fixedly mounted on the bottom end of the support block, a support block is fixedly mounted on the end of the second telescopic rod, and a cutter is fixedly mounted on the bottom end of the support block.

[0017] By adopting the above technical solution, after the tampon is fixed, the position of the cutter can be adjusted by the second telescopic rod, thereby facilitating the subsequent cutting of the tampon by the device.

[0018] Furthermore, the drive assembly includes an installation box fixedly installed on one side of the box body, one end of the reciprocating screw rotates and passes through the installation box, a reduction motor is fixedly installed in the installation box, and one end of the reciprocating screw passes through the installation box and is fixedly connected to the output shaft of the reduction motor.

[0019] By adopting the above technical solution, when the cutter position adjustment is completed, the reciprocating screw is driven to rotate by the reduction motor, and the support block and the cutter are driven to move synchronously by the reciprocating screw, so as to play the role of cutting the cotton strips.

[0020] Furthermore, two symmetrically distributed positioning blocks are fixedly mounted on the bottom end of the collection frame, and a positioning groove matching the positioning blocks is formed on the inner wall of the bottom end of the box body.

[0021] By adopting the above technical solution, the bottom end of the collection frame is provided with a positioning block, and the positioning block cooperates with the positioning groove opened on the inner wall of the bottom end of the box body, which is beneficial to maintaining the sliding stability of the collection frame and plays a role in positioning the collection frame, thereby helping to improve the stability of the placement of the collection frame.

[0022] In summary, this application includes the following beneficial technical effects:

[0023] (1) In the present application, by setting up the pressing assembly, the first telescopic rod drives the same group of mounting plates and rubber pads to move downward synchronously, so that the rubber pads contact the same group of second guide wheels. Under the thrust of the first telescopic rod, the rubber pads are deformed and meshed with the second guide wheels, thereby pressing the tampon, which is convenient for the subsequent cutting of the tampon by the equipment, and the tampon will not slip and fall outside the box, which helps to prevent the cotton wool from falling outside the box and is easy to collect.

[0024] (2) In the present application, the tension adjusting component is set to adjust the tension during the conveying of the cotton strips, so as to facilitate the stable conveying of the cotton strips and keep the cotton strips taut when they are pressed and fixed, so as to facilitate the subsequent stable cutting of the equipment.

[0025] (3) In the present application, a collection frame is provided inside the box to collect fallen cotton wool, making it easier for staff to clean up later. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] When the device is in use, the staff inserts the sliver into the box body 1 through one of the inlets and outlets 6 opened on the side wall of the box body 1, and makes the sliver pass through the rotating rod 28 and the support rod 18 in turn, and then makes the sliver pass through the other inlet and outlet 6 to enter the drawing machine for operation. The side walls of the rotating rod 28 and the support rod 18 are respectively provided with a first guide wheel 13 and a second guide wheel 22. The first guide wheel 13 and the second guide wheel 22 can limit the sliver, which is beneficial to maintain the stability of the sliver transportation, and play a role in separating the slivers, which helps to avoid the slivers from being entangled during the transportation process. The setting of the support roller 7 in the inlet and outlet 6 plays a role in supporting the sliver, and helps to avoid the slivers from being worn during transportation. When the sliver passes through the rotating rod 2 8 side wall, the rotating rod 28 plays the role of supporting the sliver, which is convenient for the transportation of the sliver, and the support rod 26 pushes the same group of mounting block 12 to move downward synchronously with the rotating rod 28 under the action of the elastic force of the same group of springs 25, and through the cooperation of the spring 25 and the support rod 26, the support rod 26 is located in the movable groove 24 and slides up and down, which plays the role of adjusting the tension during the transportation of the sliver.

[0042] A pressing assembly is provided above the two support rods 18, and the pressing assembly includes a mounting plate 10 arranged above the two support rods 18. Two groups of symmetrically distributed first telescopic rods 9 are fixedly installed on the inner wall of the top end of the box body 1. There are two first telescopic rods 9 in the same group and they are symmetrically distributed on the inner wall of the top end of the box body 1. The ends of the two first telescopic rods 9 in the same group are fixedly connected to the top of the mounting plate 10 on the same side. Rubber pads 11 are fixedly installed at the bottom ends of the two mounting plates 10. When it is necessary to cut the cotton strips, the mounting plates 10 and the rubber pads 11 in the same group are driven to move downward by the first telescopic rods 9. The rubber pad 11 is brought into contact with the second guide wheel 22 of the same group, and then the rubber pad 11 continuously moves downward under the driving force of the first telescopic rod 9 of the same group, so that the rubber pad 11 is deformed, and then the rubber pad 11 is engaged with the second guide wheel 22 of the same group, which can play the role of pressing and fixing the cotton strips, making it convenient for the equipment to cut the cotton strips later. After the cotton strips are cut, they are pressed and fixed by the rubber pad 11, so the cotton strips will not be pulled out of the box body 1 due to their own gravity, so the cotton wool from the broken end of the cotton strips can fall stably into the collection frame 8, making it convenient for the staff to collect them later.

[0043] A support box 15 is fixedly installed on the inner wall of the top of the box body 1, and the support box 15 is located between two support rods 18.

The first guide wheel 13 and the second guide wheel 22 can limit the slivers, which is beneficial to maintaining the stability of the sliver transportation, and play a role in separating the slivers, which helps to avoid the entanglement of the slivers during the transportation process. The setting of the support roller 7 in the inlet and outlet 6 plays a role in supporting the slivers, and helps to avoid the wear of the slivers during transportation. The setting of the tension adjustment component between the rotating rods 28 plays a role in adjusting the tension of the tampon during transportation, which helps to avoid slackness of the tampon during transportation, and when the tampon needs to be cut, the tampon is pressed by the pressing component to position and fix the tampon. Subsequently, the reciprocating screw rod 16 is driven to rotate by the driving component, and the reciprocating screw rod 16 drives the support block 17 to move synchronously with the cutting component, thereby cutting the tampon. The tampon is fixed by the pressing component and will not slide out of the box 1 through the inlet and outlet 6, which helps to prevent the cotton wool from floating to the outside.
