Description

Technical Field

[0001] The utility model relates to the technical field of textile components, in particular to a sliver thickness automatic stop device for a gill combing machine. Background Art

[0002] The needle combing machine is a machine that relies on the needle row roller drafting mechanism to draft, comb, and combine the fiber strips to make the fibers straight and parallel and then make them into fiber strips of a certain thickness. After the wool strips pass through the needle combing machine, the loosening and straightening state of the fibers and the uniformity of the fiber strips can be improved. During the drafting process of the needle combing machine, the wool strips may sometimes be found to be broken, which needs to be discovered by human eyes. The wool strips often break without being discovered, which ultimately affects the quality of the yarn.

[0003] In order to solve the above technical problems, a Chinese utility model patent with authorization announcement number CN211921793U discloses a self-stop device for broken slivers in a needle combing machine, comprising: a needle combing machine, a stretching roller, a stretching leather roller, a pressure roller, a bell mouth, a touch button and a controller, the bell mouth comprising: a top plate, a bottom plate and two side plates, the above four plates are surrounded to form a receiving cavity, a sliver support plate is provided in the receiving cavity, the sliver support plate is mounted on the bottom plate through an elastic member, a protrusion cooperating with the touch button is provided below the sliver support plate, the bottom plate is provided with an opening for the protrusion to pass through, and the controller is respectively connected to the touch button and the needle combing machine. Its working principle is: the strip is pressed on the strip support plate in the bell mouth, the spring under the strip support plate is in a compressed state, and the protrusion under the strip support plate is in contact with the touch button. When the strip breaks, the strip will not be pressed on the strip support plate in the bell mouth, and the compressed spring will be reset, thereby driving the protrusion to move upward and disengage from the touch button. At this moment, the touch button transmits a signal to the controller, and the controller then transmits the signal to the needle combing machine, notifying the needle combing machine to stop.

[0004] However, the prior art has the following problems: if the sliver breaks at the rear end of the bell mouth, the sliver at the front end of the bell mouth will still squeeze the sliver support plate, forcing the protrusion under the sliver support plate to be in contact with the touch button, and then the touch button cannot be triggered to transmit the signal to the controller, so the carding machine cannot be stopped in time, which ultimately affects the quality of the yarn. Utility Model Content

[0005] The purpose of the utility model is to provide a sliver thickness automatic stop device for a gill combing machine, so as to solve the technical problem raised by the above background technology that the existing sliver automatic stop devices for gill combing machines on the market cannot stably transmit signals to a controller to stop the gill combing machine after the sliver breaks.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sliver thickness automatic stop device for a gilling machine, comprising a frame, and also comprising a transmission assembly for transmitting slivers, the transmission assembly comprising at least one rotating roller and at least one end shaft arranged on the side of the rotating roller, the end shaft being rotatably connected to a rotating groove provided in the frame;

[0014] As a preferred technical solution of the utility model, the guide assembly includes at least two guide parts, and the guide part includes a guide rod, which is provided on the upper surface of the support plate, and the guide rod is slidably matched with a guide groove opened on the surface of the movable plate.

[0015] As a preferred technical solution of the utility model, there are two rotating rollers, and one of the rotating rollers is connected with an adjustment structure so as to adjust the distance between the two rotating rollers to accommodate strips of different thicknesses.

[0016] As a preferred technical solution of the utility model, the adjustment structure includes at least two adjustment parts, and the adjustment parts include:

[0017] A slider is provided with a rotating hole for inserting the end shaft of the rotating roller, and the slider is slidably matched with a sliding groove provided on the side of the frame;

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] The utility model arranges a roller for rotation inside a frame and connects a cam to the axial end of the roller. The sliver can be used to drive the roller to rotate, thereby driving the cam to rotate, so that the cam drives the movable plate to move downward, and a reset member is arranged to reset the movable plate, so that the movable plate can reciprocate and touch the button of the interval switch to keep the needle combing machine running. When the sliver breaks, the winding roller cannot continue to drive the sliver to move, and the second roller stops running quickly, so that the button of the interval switch cannot be pressed intermittently, and the needle combing machine stops, effectively avoiding the accident that the needle combing machine is still running after the sliver breaks.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] See also Figure 1-Figure 4 The utility model provides a technical solution: a sliver thickness automatic stop device for a gill combing machine, comprising a frame 1, a support plate 2 is installed at the lower end of the frame 1, and a mounting hole 3 is opened on the surface of the support plate 2;

[0030] The above technical solution can be used to conveniently install the frame 1 on the needle combing machine, fit the support plate 2 with the needle combing machine mounting platform, use bolts to pass through the mounting holes 3, and thread the other end of the bolts to the mounting platform to complete the installation.

[0031] like Figure 3 As shown, the sliver thickness automatic stop device of the gill combing machine also includes:

[0032] A transmission assembly, which is used to transmit strips, comprises at least one rotating roller and at least one end shaft arranged on the side of the rotating roller, the end shaft being rotatably connected to a rotating groove 13 provided in the frame 1; specifically, the rotating roller is a second rotating roller 11, and a first end shaft 8 is provided at both ends thereof; a cam 14 is connected to the first end shaft 8; a movable plate 15, the upper surface of which contacts the cam 14; specifically, a guide assembly is provided at the upper end of the support plate 2 to guide the movement of the movable plate 15; more specifically, the guide assembly comprises at least two guide parts, the guide part comprises a guide rod 17, which is provided on the upper surface of the support plate 2, and the guide rod 17 is slidably matched with a guide groove 16 provided on the surface of the movable plate 15;

[0033] An interval switch 20 is provided below the movable plate 15 to control the start and stop of the gilling machine. The interval switch 20 can be connected to the gilling machine using a time controller;

[0034] A reset member, which is used to drive the movable plate 15 to reset after the cam 14 presses the movable plate 15 downward to touch the button of the interval switch 20; specifically, the reset member includes a spring 18, one end of which is connected to the bottom end of the movable plate 15, and the other end of the spring 18 is connected to the upper surface of the support plate 2;

[0035] By adopting the above technical solution, the second roller 11 can drive the movable plate 15 to move back and forth downward to touch the button of the interval switch 20, so that the sliver of the needle combing machine is pulled out for a section through the frame 1, and the other end of the sliver is connected to the winding roller. The lower end of the sliver contacts the upper surface of the second roller 11. When the winding roller pulls the sliver, it will synchronously drive the second roller 11 to rotate. The second end shaft 12 on one side of the second roller 11 drives the cam 14 to rotate, and the cam 14 pushes the movable plate 15 to move downward along the guide rod 17. The movable plate 15 contacts the button of the interval switch 20. The interval switch 20 needs to be pressed regularly, otherwise the needle combing machine will be powered off and stopped. After the plate 15 drops to the lowest position, the spring 18 is compressed, and the spring 18 pushes the movable plate 15 to rise and reset, thereby realizing one round of operation, so that the contact head 19 reciprocates to touch the interval switch 20 to keep the needle combing machine running. When the sliver breaks, the winding roller cannot continue to drive the sliver to continue moving, and the second roller 11 stops running soon, and then the movable plate 15 continues to press the button on the surface of the interval switch 20, or the movable plate 15 is separated from the button on the surface of the interval switch 20, so that the interval switch 20 controls the needle combing machine to stop, effectively avoiding the needle combing machine from continuing to run after the sliver breaks, thereby preventing accidents.

[0036] Further, such as Figure 1 As shown, the lower end of the movable plate 15 is provided with a contact head 19 that cooperates with the button of the interval switch 20;

[0037] The adoption of the above technical solution can ensure that the movable plate 15 touches the button of the interval switch 20 more accurately.

[0038] Further, such as Figure 1 and Figure 4 As shown, the roller has two rollers, namely the first roller 7 and the second roller 11, and the first roller 7 is connected with an adjustment structure so as to adjust the distance between the two rollers to adapt to strips of different thicknesses; specifically, the adjustment structure includes at least two adjustment parts, and the adjustment part includes: a slider 4, which is provided with a rotation hole 6 for inserting the first end shaft 8 of the first roller 7, and the slider 4 is slidably matched with a slide groove 5 provided on the side of the frame 1; an electric push rod 10, the bottom of which is fixed in the slide groove 5, and the output end of the electric push rod 10 is connected to the slider 4;

[0039] The above technical solution can ensure that the strip is in close contact with the second roller 11 without slipping. The electric push rod 10 is started to drive the slider 4 to slide downward along the slide groove 5. The slider 4 drives the first end shaft 8 to move downward, and then drives the first roller 7 to move downward, thereby shortening the distance between the first roller 7 and the second roller 11 to clamp the strip. When the winding roller pulls the strip, it will synchronously drive the first roller 7 and the second roller 11 to rotate.

[0040] Furthermore, Figure 3 and Figure 4As shown, an anti-skid pad 9 is provided on the outside of the roller to increase the friction coefficient between the roller and the strip;

[0041] The above technical solution can prevent the rotating roller and the strip from slipping, thereby ensuring that the strip can drive the second rotating roller 11 to rotate stably.

[0042] Working principle: When in use, first pull out a section of the sliver of the gilling machine through the frame 1, connect the other end of the sliver to the winding roller, start the electric push rod 10 to drive the slider 4 to slide down along the slide groove 5, the slider 4 drives the first end shaft 8 to move downward, and then drives the first roller 7 to move downward, thereby shortening the distance between the first roller 7 and the second roller 11 to clamp the sliver, and when the winding roller pulls the sliver, it will synchronously drive the first roller 7 and the second roller 11 to rotate, and the second end of one side of the second roller 11 The shaft 12 drives the cam 14 to rotate, and the cam 14 pushes the movable plate 15 to move down along the guide rod 17, so that the contact head 19 at the lower end of the movable plate 15 contacts the button of the interval switch 20. The interval switch 20 needs to be pressed regularly, otherwise the pin combing machine will be powered off and stopped. When the movable plate 15 drops to the lowest position, the spring 18 is compressed, and the spring 18 pushes the movable plate 15 to rise and reset, thereby realizing a round of operation, so that the contact head 19 touches the interval switch 20 reciprocatingly, so that it keeps the pin combing machine running;

[0043] When the sliver breaks, the winding roller cannot continue to drive the sliver to move, and the second roller 11 stops running quickly, causing the movable plate 15 to continue pressing the button on the surface of the interval switch 20, or the movable plate 15 is separated from the button on the surface of the interval switch 20, so that the interval switch 20 controls the needle combing machine to stop, effectively avoiding the needle combing machine from continuing to run after the sliver breaks, thereby preventing accidents.
