[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0040] When the guide mechanism is working normally, the roller and the pressure roller are in contact with each other, and the cotton strips are stably controlled between the two. However, in actual production, due to the excessive traction of the cotton strip pulling device, or the cotton strips are too thin, there is a possibility of cotton strips breaking. In the case of cotton strip breaking, the guide mechanism needs to stop working, and because the force on the cotton strips mainly occurs on the guide roller assembly and the traction device, the breaking point will often appear between the two positions. In the related technology, it is necessary to rely on manpower to lift the pressure roller to complete the connection of the broken cotton strips. Therefore, there are problems of high labor costs and low equipment working efficiency.

[0041] In view of this, an embodiment of the present application proposes a guide bar mechanism to at least solve the above technical problem.

[0042] Figure 1 A partial schematic structural diagram of a guide bar mechanism provided in an embodiment of the present application, such as Figure 1 As shown, the above-mentioned sliver guide mechanism includes: a frame 100, a sliver guide roller 200, a sliver guide roller assembly 300 and a driving member 400. Among them, the sliver guide roller 200 is arranged on the frame 100, and the sliver guide roller 200 is used to pull the sliver 510'; the sliver guide roller assembly 300 is arranged on the frame 100, and the sliver guide roller assembly 300 abuts against the surface of the sliver guide roller 200 to stabilize the sliver 510'; the driving member 400 is used to drive the sliver guide roller assembly 300 away from the surface of the sliver guide roller 200.

[0043] For example, Figure 1 As shown, the above-mentioned guide roller 200 and guide roller pressure assembly 300 are both arranged on the frame 100. The frame 100 can stabilize and support the guide roller 200 and the guide roller pressure assembly 300, thereby reducing the vibration of the traction cotton strip 510' when the guide mechanism is working, and improving the quality of the product.

[0044] The slivers 510′ in the sliver can 500′ are guided by the aforementioned sliver pulling device (not shown in the figure) to pass through between the sliver guide roller assembly 300 and the sliver guide roller 200. The sliver guide roller 200 controls the tension of the slivers 510′ to pull the slivers 510′. The sliver guide roller assembly 300 abuts against the surface of the sliver guide roller 200, that is, when the sliver guide roller assembly 300 and the sliver guide roller 200 are in contact with each other, a certain interaction force is generated. This interaction force can prevent the slivers 510′ between the sliver guide roller assembly 300 and the sliver guide roller 200 from slipping, thereby playing a stabilizing role.

[0045] Based on the above-mentioned guide roller 200 and guide roller pressure assembly 300, the embodiment of the present application is provided with a driving member 400, which can drive the guide roller pressure assembly 300 away from the surface of the guide roller 200. When the cotton strip 510' breaks, there is no need to lift the pressure roller assembly manually, thereby saving labor costs and improving the working efficiency of the equipment.

[0046] In some examples, Figure 2 A schematic block diagram of a guide bar mechanism provided in an embodiment of the present application, such as Figure 2 As shown, the strip guiding mechanism further includes: a controller 800 for receiving a check signal and controlling a power source 900 to provide power to the driving member 400 so as to make the driving member 400 work. The check signal is related to the shape of the cotton strip 510' being pulled.

[0047] Exemplarily, the inspection signal may be sent by a detection device (not shown) in a production plant. The detection device may be a photoelectric detection device. When the shape of the tampon 510′ changes, such as when it breaks, the detection device sends an inspection signal to the controller 800. The controller 800 controls the power source 900 to provide power to the driving member 400 to enable the driving member 400 to work.

[0048] It should be noted that the controller 800 can be a processing device commonly used in industrial production, and can be a single chip microcomputer or a PLC (Programmable Logic Controller, Programmable Logic Controller 800) and other intelligent devices. The power source 900 is used to provide power, such as a power supply, and the specific type depends on the type of the driving member 400.

[0049] In the embodiment of the present application, the controller 800 is arranged to provide power to the driving member 400 through the power source 900 upon receiving the inspection signal reflecting the abnormal shape of the cotton strip 510′, so that the driving member 400 works and the guide strip pressure roller assembly 300 is kept away from the surface of the guide strip roller 200. Compared with manually controlling the driving member 400, the efficiency is higher.

[0050] Figure 3 A schematic structural diagram of a guide roller assembly provided in an embodiment of the present application, combined with Figure 1 and Figure 3 As shown, in some examples, the guide roller assembly 300 includes a roller head, a mounting rod 320 and a support arm 330. The roller head is in contact with the surface of the guide roller 200 to stabilize the sliver 510'; the mounting rod 320 is disposed on the frame 100, and one end of the support arm 330 is rotatably connected to the roller head, and the other end is rotatably connected to the mounting rod 320.

[0051] For example, Figure 3As shown, the support arm 330 can rotate in a plane with the mounting rod 320 as the axis, so as to drive the roller head away from or close to the guide roller 200, so that the direction of the force exerted by the roller head on the surface of the guide roller 200 is fixed. At the same time, the support arm 330 is rotatably connected to the roller head, and the roller head can rotate naturally under the friction force of the traction cotton strip 510', thereby reducing the resistance to the cotton strip 510' and reducing the possibility of the cotton strip 510' breaking.

[0052] It should be noted that the connection between the support arm 330 and the mounting rod 320 can be set to a smaller friction force, that is, after the above-mentioned driving member 400 removes the force, the support arm 330 can fall naturally under the action of gravity. In this way, when the sliver 510' is broken, the driving member 400 drives the support arm 330 to rise, the operator completes the connection of the sliver 510', removes the driving force of the driving member 400, and the support arm 330 falls naturally without manual operation. The roller head contacts the guide roller 200 again, and the guide machine continues to work, thereby further reducing labor costs and improving the working efficiency of the equipment.

[0053] In some examples, a buckle may be provided at the rotational connection between the support arm 330 and the mounting rod 320 to prevent the support wall from rotating too much.

[0054] In some examples, such as Figure 3 As shown, the guide strip pressing roller assembly 300 further includes: a pressing roller rotating arm 340, which is fixedly connected to the support arm 330 and is used to drive the support arm 330 to lift.

[0055] Exemplarily, through a fixed connection, that is, the pressure roller arm 340 and the support arm 330 will not produce relative displacement, so that the above-mentioned driving member 400 can transmit the driving force to the support arm 330 through the pressure roller arm 340, and the support arm 330 drives the roller head away from the surface of the guide roller 200.

[0056] It should be noted that the above-mentioned fixed connection can be a direct connection or an indirect connection. Direct connection refers to a connection method without an intermediate medium between the two, such as welding, which has high strength; indirect connection refers to a connection method with an intermediate medium between the two. For example, an intermediate piece can be set up, connected to the support arm 330 and the pressure roller arm 340, and the pressure roller arm 340 and the intermediate piece can be in a snap-on form to facilitate disassembly and replacement.

[0057] In some examples, such as Figure 1 As shown, the strip guide roller assembly 300 further includes: a cotton guide ring 350, which is disposed on the mounting rod 320 and is used for sleeve-mounting the cotton strip 510'.

[0058] For example, the cotton guide ring 350 can cover the tampon 510' being pulled to prevent the tampon 510' from being too long and getting entangled with the protrusion of the device, resulting in accidental breakage. The cotton guide ring 350 can be round, square or triangular in shape, which is not specifically limited in the embodiment of the present application.

[0059] In some examples, such as Figure 3 As shown, the driving member 400 includes a cylinder, which can push the pressure roller arm 340 when an air source is input, so that the roller head is away from the surface of the guide roller 200.

[0060] In some examples, such as Figure 3 As shown, the driving member 400 includes an electric cylinder, which can push the pressure roller arm 340 when power is input, so that the roller head is away from the surface of the guide roller 200.

[0061] Exemplarily, the driving member 400 may be a pneumatic cylinder or an electric cylinder, which may generate power through a piston when an air source or an electric power source is used as power, respectively, and when the air source or the electric power source is removed, the piston may return to its initial position under the action of a spring or a similar element.

[0062] It should be noted that a micro cylinder or electric cylinder can be used, which is convenient for installation and saves equipment space.

[0063] In some examples, such as Figure 3 As shown, the driving member 400 further includes a fixing seat 410 fixedly connected to the mounting rod 320 for fixing the pneumatic cylinder or electric cylinder.

[0064] Exemplarily, the air cylinder or electric cylinder is fixed by the fixing seat 410, i.e., the middle piece, which can not only stabilize the air cylinder or electric cylinder, but also facilitate the disassembly of the air cylinder or electric cylinder.

[0065] In order to better understand the guide bar mechanism provided in the embodiment of the present application, the embodiment of the present application provides the structural position changes of the guide bar mechanism under different working conditions. Figure 4 A schematic structural diagram of a guide roller assembly in a falling state provided in an embodiment of the present application, Figure 5 A schematic structural diagram of a guide roller assembly in a raised state provided in an embodiment of the present application, combined with Figure 4 and Figure 5 , the working of the guide bar mechanism provided in the embodiment of the present application is described:

[0066] like Figure 4 As shown, in a normal working room, the guide strip pressure roller assembly 300 and the guide strip roller 200 abut against each other, and the cotton strip 510' is stably transported under the action of the aforementioned cotton strip pulling device (not shown in the figure).

[0067] like Figure 5 As shown, the above-mentioned cotton strip 510' is accidentally broken. The above-mentioned detection equipment (such as photoelectric detection equipment) sends out the above-mentioned inspection signal after detecting it, and the strip guiding mechanism stops working. After receiving the inspection signal, the controller 800 controls the power source 900 to connect the air source to the cylinder, and the cylinder pushes the above-mentioned pressure roller arm 340 to lift the roller body 310. At this time, the operator can complete the connection of the cotton strip 510'.

[0068] After the splicing of the sliver 510' is completed, the operator restarts the guide mechanism, the controller 800 disconnects the air source, the cylinder stops working, and the support arm 330 falls to the working position under the action of its own weight. Figure 3 shown.

[0069] In some examples, combined Figure 1 and Figure 3 As shown, the mounting rod 320 is a hollow structure, and the mounting rod 320 is used to pass a power line tube 420, and the power line tube 420 is used to transmit the input gas source to the cylinder, or transmit the input power to the electric cylinder.

[0070] For example, when the driving member 400 is a pneumatic cylinder or an electric cylinder, a power source 900 is required to enable both to work properly. Considering that the sliver guide mechanism may be entangled with many slivers 510' in actual production, the mounting rod 320 may be set to a hollow structure, so as to provide a corresponding air source or power source for the pneumatic cylinder or the electric cylinder. The power line tube 420 of the power source 900 may pass through the mounting rod 320 and be connected to the pneumatic cylinder or the electric cylinder, thereby reducing entanglement with the slivers 510' and improving the reliability of normal operation of the equipment.

[0071] Figure 6 A schematic structural diagram of a guide bar mechanism provided in an embodiment of the present application, such as Figure 6 As shown, in some examples, the guide strip mechanism further includes a conveyor belt 700 disposed in the frame 100 , and the conveyor belt is used to drive the guide strip roller 200 to rotate.

[0072] For example, Figure 6 As shown, a conveyor belt 700 can be arranged in the frame 100. The conveyor belt 700 drives the guide roller 200 to rotate, which can provide a better stretching effect on the pulled cotton strip 510'. In addition, by controlling the conveying speed of the conveyor belt 700, the rotation speed of the guide roller 200 is adjusted, thereby adjusting the pulling speed of the cotton strip 510'.

[0073] According to some embodiments, Figure 6As shown, there are a plurality of the guide rollers 200 , which are distributed on both sides of the frame 100 along the pulling direction of the cotton strips 510 ′; wherein each guide roller 200 corresponds to at least one guide roller pressure assembly 300 .

[0074] It should be noted that in order to improve the working efficiency of pulling the cotton strips 510', a plurality of cotton strips 510' are often pulled at the same time in a drawing machine, and a plurality of guide rollers 200 can be set. The plurality of guide rollers 200 are distributed on both sides of the frame 100 along the pulling direction of the cotton strips 510', and each guide roller 200 must cooperate with at least one guide roller pressure assembly 300, so as to ensure that each guide roller 200 and guide roller pressure assembly 300 can pull at least one cotton strip 510'.

[0075] For example, Figure 6 As shown, the frame 100 can be in the shape of a long strip and fixed to the ground by a column 600. Eight guide rollers 200 are evenly distributed on both sides of the frame 100, with four on each side. The traction slivers 510' are arranged on both sides of the frame 100. Each guide roller 200 is provided with at least one traction sliver 510'. A conveyor belt 700 can be arranged inside the frame 100 to drive the eight guide rollers 200 to rotate.

[0076] In some examples, such as Figure 6 As shown, each guide roller 200 corresponds to two guide roller pressure roller assemblies 300, one of which is arranged at the end of the guide roller 200 away from the frame 100, and the other is arranged at the end of the guide roller 200 close to the frame 100.

[0077] It should be noted that in order to prevent the cotton strips 510′ on the same guide roller 200 from getting entangled, the traction cotton strips 510′ on one guide roller 200 are arranged separately. Therefore, one guide roller assembly 300 is set at one end away from the frame 100, and the other is set at one end close to the frame 100.
