Description

Technical field:

[0002] The utility model relates to an improved structure for sucking and discharging debris of a roving machine. Background technology:

[0004] The applicant applied for the Chinese patent "Suction and exhaust cleaning mechanism of roving machine" in December 2018

[0005] Announcement No. CN209428667U, comprising a roving frame and a track arranged above the roving frame and along the length direction of the roving frame, a reciprocating car body is provided on the track, a first suction pump and a suction main pipe connected to the air inlet of the first suction pump are provided on the reciprocating car body, the suction main pipe is connected to the first ends of a plurality of suction branch pipes, the second ends of the suction branch pipes are close to the working table of the roving frame, the air outlet of the first suction pump is connected to the first end of an intermediate cylinder for storing debris, the second end of the intermediate cylinder extends out of the car body, and the second end of the intermediate cylinder is covered with a rubber sheet, the rubber sheet is cross-cut with a plurality of cutting seams, one end of the track is provided with a discharge pipe that can extend into the intermediate cylinder, a second suction pump is provided on the discharge pipe, and an opening and closing door is provided on the side of the discharge pipe facing the car body.

[0006] Although this patent can absorb and discharge the debris on the roving machine in a centralized manner, when the middle cylinder lifts the wedge block, the wedge block also exerts a reaction force on the car body, causing the driving wheel at the bottom of the car body to slip, affecting the middle cylinder from being inserted into the discharge pipe (that is, the discharge pipe extending into the middle cylinder).

[0007] In addition, the rubber sheet installed on the end of the intermediate cylinder has a slow rebound speed after the discharge pipe is separated from the intermediate cylinder, so that when the first suction pump starts working, there is still a large gap in the cutting seam of the rubber sheet, which makes it easy for debris to be discharged from the gap, affecting the workshop environment. Summary of the invention:

[0009] In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide an improved structure for suction and exhaust cleaning of debris from a roving frame, which is reasonably designed and helps to ensure that the discharge pipe can smoothly extend into the intermediate cylinder.

[0010] The utility model relates to an improved structure for sucking and discharging debris from a roving machine, comprising a roving machine and a track arranged above the roving machine and along the length direction of the roving machine, the track being provided with a reciprocating carriage, the reciprocating carriage being provided with a first suction pump and a suction main pipe connected to an air inlet of the first suction pump, the suction main pipe being connected to first ends of a plurality of suction branch pipes, the second ends of the suction branch pipes being close to a working table of the roving machine, the air outlet of the first suction pump being connected to a first end of an intermediate cylinder for storing debris, the second end of the intermediate cylinder extending out of the car body, and a rubber sheet being provided at the second end of the intermediate cylinder, the rubber sheet being cross-cut with a plurality of cutting seams, one end of the track being provided with a discharge pipe capable of extending into the intermediate cylinder, the discharge pipe being provided with a second suction pump, the discharge outlet of the second suction pump being connected to a barrel for containing debris;

[0011] The feature is that: the end of the discharge pipe facing the vehicle body has a pointed cone-shaped shell, the pointed cone-shaped shell is provided with air holes, the outer periphery of the discharge pipe is provided with a travel switch for starting and closing the second suction pump, and when the pointed cone-shaped shell of the discharge pipe extends into the middle cylinder body, the end of the middle cylinder triggers the travel switch to start the second suction pump.

[0012] Preferably, the rubber sheet is radially cut with 4-6 cutting seams starting from its center to divide the rubber sheet into several sheets, and the cutting seams do not penetrate to the periphery of the rubber sheet. The periphery of the rubber sheet is fixed on the second end face of the intermediate cylinder, and a rubber ring is provided on the surface of the rubber sheet away from the second suction pump, and the rubber ring is evenly distributed with several fixing points fixedly connected to the sheet.

[0013] Preferably, the periphery of the rubber sheet is fixed to the second end surface of the intermediate cylinder by glue, and the fixing point of the rubber ring is fixedly connected to the sheet by glue.

[0014] Preferably, the vent holes on the pointed cone-shaped shell are triangular in shape and are arranged in a circular array on the pointed cone-shaped shell, with the upper end points of the triangular vent holes being close to the tip of the pointed cone-shaped shell.

[0015] The utility model discloses an improved working method of the debris suction and discharge cleaning structure of the roving machine, which sucks the debris on the roving machine into the intermediate cylinder through the suction branch pipe, the suction main pipe and the first suction pump, and the car body moves on the track. When the car body approaches the discharge pipe and continues to move, the end of the discharge pipe pushes the cutting seam on the rubber sheet to enter the intermediate cylinder. When the end of the intermediate cylinder contacts and triggers the travel switch, the second suction pump starts to work, and the debris in the intermediate cylinder is discharged into the barrel body through the second suction pump.

[0016] Since the wedge block is eliminated in the present application, the extra power of the vehicle body to push the wedge block upward is avoided, which is conducive to the discharge pipe extending into the middle cylinder, and the second suction pump only starts working after the travel switch is triggered at the end of the middle cylinder, reducing the electric energy wasted by the continuous operation of the second suction pump, which is conducive to energy saving and consumption reduction.

[0024] The utility model discloses an improved structure for cleaning debris suction and discharge of a roving frame, comprising a roving frame 1 and a track 2 arranged above the roving frame 1 and along the length direction of the roving frame, wherein the track can be two relatively parallel angle irons, a reciprocating vehicle body 3 is arranged on the track 2, four driving wheels 17 on the vehicle body 3 travel on the angle iron track, a first suction pump 4 and a suction main pipe 5 connected to the air inlet of the first suction pump are arranged on the reciprocating vehicle body 3, the suction main pipe 5 is connected to the first ends of a plurality of suction branch pipes 6, wherein the suction branch pipes 6 can be plastic corrugated pipes, the suction main pipe 5 can be a rigid pipe body made of stainless steel, the second end of the suction branch pipe 6 is close to the working table of the roving frame 1, and the air outlet of the first suction pump 4 is connected to the first end of an intermediate cylinder 7 for storing debris.

[0025] The second end of the intermediate cylinder 7 extends out of the vehicle body 3, and a rubber sheet 8 is provided at the second end of the intermediate cylinder 7, on which a plurality of cutting slits 24 are cross-cut (the rubber sheet 8 is provided to play a sealing role so that the debris K entering the intermediate cylinder 7 will not be directly discharged under the action of the first suction pump 4, and the plurality of cutting slits 24 are provided to allow the discharge pipe 9 to pass through the rubber sheet 8 and be inserted into the intermediate cylinder 7).

[0026] Specifically, the rubber sheet 8 is radially cut with 4-6 cutting seams 24 starting from its center to divide the rubber sheet 8 into several sheets. The cutting seams 24 do not penetrate to the periphery of the rubber sheet 8. The periphery of the rubber sheet 8 is fixed to the second end face of the intermediate cylinder 7 by glue. A rubber ring A2 is provided on the surface of the rubber sheet 8 away from the second suction pump 10. The rubber ring A2 is evenly distributed with a plurality of fixing points A3 fixedly connected to the sheet (the rubber ring A2 is bonded at the fixing points by glue when the rubber sheet 8 is in the initial plane state); the fixing points of the rubber ring are fixedly connected to the sheet by glue. The cross-section of the rubber ring A2 can be circular or rectangular, but the contact area of ​​the rectangular rubber ring and the rubber sheet 8 is larger, and the rubber ring A2 is circular under normal conditions.

[0027] A discharge pipe 9 capable of extending into the intermediate cylinder 7 is fixedly provided at one end of the track 2 (the discharge pipe 9 is fixed relative to the machine body, and the intermediate cylinder 7 moves with the machine body), and a second suction pump 10 is provided on the discharge pipe 9, and a discharge port of the second suction pump 10 is connected to a barrel 25 for containing debris, a cloth bag is placed in the barrel, and the bag mouth of the cloth bag is connected to the discharge port of the second suction pump 10 through a pipeline connection. Under the action of the second suction pump 10, the discharge pipe 9 extending into the intermediate cylinder 7 can discharge the debris into the barrel 25.

[0028] The end of the discharge pipe 9 facing the vehicle body has a conical shell, and a vent hole A4 is arranged on the conical shell. The outer periphery of the discharge pipe 9 is provided with a travel switch A1 for opening and closing the second suction pump 10. When the conical shell of the discharge pipe 9 extends into the middle cylinder 7, the end of the middle cylinder 7 triggers the travel switch A1 to start the second suction pump 10. When the end of the middle cylinder 7 does not contact and trigger the travel switch A1, the second suction pump 10 does not work. In this way, the second suction pump 10 only works when it is necessary to suck debris from the middle cylinder 7, which is beneficial to energy saving and consumption reduction.

[0029] In order to improve the air flow effect, the vent holes A4 on the pointed cone shell are triangular in shape and arranged in a circular array on the pointed cone shell, with the upper end points of the triangular vent holes close to the tip of the pointed cone shell.

[0030] Since a rubber ring A2 is provided on the surface of the rubber sheet 8 away from the second suction pump 10, and a plurality of fixing points A3 are evenly distributed on the rubber ring A2 and fixedly connected to the sheet body (the rubber ring A2 is bonded at the fixing points by glue when the rubber sheet 8 is in the initial plane state), after the discharge pipe 9 leaves the intermediate cylinder 7 (that is, the discharge pipe 9 no longer pushes the cutting slit 24 of the rubber sheet 8 to extend into the intermediate cylinder 7), each sheet of the rubber sheet 8 is subjected to the contraction effect of the rubber ring A2, so that the rubber sheet 8 can quickly return to the initial plane state (that is, the two side surfaces of the rubber sheet 8 are in a plane state), so that the cutting slit 24 is closed, and there will be no large gap to cause debris to be discharged.

[0031] The working method of the improved structure for suction and discharge cleaning of debris of the roving machine of the utility model is that the debris on the roving machine is sucked into the intermediate cylinder through the suction branch pipe, the suction main pipe and the first suction pump, and the car body moves on the track. When the car body approaches the discharge pipe and continues to move, the end of the discharge pipe pushes open the cutting seam 24 on the rubber sheet 8 and enters the intermediate cylinder. When the end of the intermediate cylinder contacts and triggers the travel switch, the second suction pump 10 starts to work, and the debris in the intermediate cylinder is discharged into the barrel body through the second suction pump.

[0032] Since the wedge block is eliminated in the present application, the extra power of the vehicle body to push the wedge block upward is avoided, which is conducive to the discharge pipe extending into the middle cylinder, and the second suction pump 10 starts working only after the travel switch is triggered at the end of the middle cylinder, reducing the electric energy wasted by the continuous operation of the second suction pump 10, which is conducive to energy saving and consumption reduction.
