Description

Technical Field

[0001] This utility model relates to the field of loose lint removal technology, specifically a device for removing loose lint from carpet surfaces. Background Technology

[0002] Carpets are floor coverings made from natural fibers such as cotton, linen, wool, silk, and grass, or chemically synthesized fibers, through manual or mechanical processes of weaving, tufting, or spinning. After production, carpets are prone to having loose fibers attached to their surface, so it is necessary to design a loose fiber removal device for carpet production.

[0003] A carpet production loose lint removal device disclosed in Chinese Patent No. CN221029215U uses only a cleaning brush to comb and clean loose lint. This method cannot remove stubborn loose lint with strong adhesion to the carpet surface, which can easily leave loose lint residue. Furthermore, due to the lack of an adaptive adjustment structure for the pressure between the cleaning brush and the carpet, it is difficult to accurately control the adhesion when dealing with carpets of different thicknesses and specifications. If the adhesion is too loose, loose lint will be missed, and if the adhesion is too tight, it can easily damage the carpet surface pile or create indentations, affecting the cleaning effect and carpet quality.

The preliminary cleaning brush assembly first pre-combs the carpet surface to loosen stubborn lint with strong adhesion. Subsequently, the adhesive tape adhesion mechanism uses the adhesive properties of the lint-adhesive tape to firmly adhere to and collect the pre-combed lint.

At the same time, the device is equipped with a pressure adaptive adjustment component that can monitor and fine-tune the adhesion pressure between the tape and the carpet in real time. Combined with the lifting adjustment mechanism, the height can be preset according to the carpet thickness to ensure that the preliminary cleaning brush assembly, the adhesive tape adhesion mechanism, and carpets of different thicknesses always maintain an ideal fit. This avoids lint leakage due to excessively loose adhesion, and also prevents damage or indentations to the carpet surface pile due to excessively tight adhesion, thus ensuring cleaning effect and carpet quality.

[0016] Please see Figure 1-5 A carpet lint removal device includes a workbench 32, a transverse drive mechanism 33 located outside the workbench 32, a lifting adjustment mechanism 34 located above the transverse drive mechanism 33, a preliminary cleaning brush assembly connected to one side of the lifting adjustment mechanism 34 and located above the workbench 32, and two pressure adaptive adjustment components located above the lifting adjustment mechanism 34 and respectively on both sides of the width direction of the workbench 32, a tape adhesion mechanism 35 located above the two pressure adaptive adjustment components and spanning above the workbench 32, and two carpet side pressing mechanisms embedded in the upper side of the workbench 32 and spaced apart along its length direction; the preliminary cleaning brush assembly and the tape adhesion mechanism 35 are spaced apart along the driving direction of the transverse drive mechanism 33, and the preliminary cleaning brush assembly is located in front of the tape adhesion mechanism 35.

[0017] This application further proposes that the workbench 32 includes a support body 1, side mounting plates 6 welded to both ends of the support body 1, two grooves 2 arranged at intervals along the length of the support body 1 on the lower side, two pressure grooves 3 arranged on the upper side of the support body 1 corresponding to the two grooves 2, a negative pressure adsorption chamber 4 located inside the support body 1 and between the two grooves 2, and a plurality of openings 5 ​​arranged in a matrix uniformly on the upper side of the support body 1; the openings 5 ​​communicate with the upper side of the negative pressure adsorption chamber 4; the carpet side pressing mechanism includes two second cylinders 26 arranged at intervals along the width of the support body 1 on the upper side of the grooves 2, and pressure blocks 27 connected to the output ends of the two second cylinders 26 and adapted to the pressure grooves 3; the pressure blocks 27 are made of silicone material, the two pressure blocks 27 are symmetrically arranged, and the opposite end is provided with an arc-shaped chamfer; the upper part of the opposite side of the two pressure grooves 3 is provided with an arc-shaped chamfer with a radius of 5-8mm.

[0018] Among them, the lower surface of the side mounting plate 6 is flush with the lower surface of the support platform body 1; the negative pressure adsorption chamber 4 is integrally formed inside the support platform body 1; the two second cylinders 26 are fixed to the upper side of the inside of the groove 2 by cylinder seat bolts, and their output ends are set upward and connected to the lower side of the pressure block 27 by threads; the pressure block 27 is adapted to the shape of the pressure groove 3.

[0019] Specifically, the matrix-style opening 5 is connected to the negative pressure adsorption chamber 4, and together with the negative pressure fan 28, it can form a uniform adsorption force to ensure that the center of the carpet is flat and fixed; the second cylinder 26 drives the pressure block 27 to embed into the corresponding pressure groove 3, so as to achieve flexible pressing of the carpet edge. The silicone material and the arc chamfer design can not only avoid damaging the carpet edge, but also enhance the friction with the carpet and prevent the edge from lifting.

[0020] This application further proposes that a negative pressure fan 28 is fixed to the lower side of the support platform body 1 by bolts, and an air pipe 29 is connected to the air inlet end of the negative pressure fan 28. The end of the air pipe 29 away from the negative pressure fan 28 extends into a groove 2 and is sealed and connected to one side of the negative pressure adsorption chamber 4.

[0021] The air inlet of the negative pressure fan 28 is sealed to one end of the air pipe 29 via a flange. A negative pressure resistant rubber gasket is installed at the flange connection to prevent air leakage. The air pipe 29 is made of PVC and its diameter is adapted to the air intake of the negative pressure fan 28. The end of the air pipe away from the negative pressure fan 28 passes through the side wall of the groove 2 on the lower side of the support platform body 1, extends into the groove 2, and is sealed to one side opening of the negative pressure adsorption chamber 4 by welding. The weld is polished smooth and coated with sealant.

[0022] Specifically, the negative pressure fan 28 is sealed and connected to the negative pressure adsorption chamber 4 through the air pipe 29, which can form a stable negative pressure in the negative pressure adsorption chamber 4. The matrix-type openings 5 ​​on the upper side of the support platform body 1 can generate adsorption force evenly, firmly fixing the middle of the carpet and preventing the carpet from shifting or wrinkling when the horizontal drive mechanism 33 moves the cleaning component, thus ensuring the continuous removal trajectory of loose fibers.

[0023] This application further proposes that the tape adhesion mechanism 35 includes two vertical plates 19 spaced apart along the width direction of the support platform body 1, a second rotating shaft 23 and a first rotating shaft 21 rotatably connected to opposite sides of the two vertical plates 19 via deep groove ball bearings and staggered from top to bottom, a tape roll 24 disposed on the outer wall of the second rotating shaft 23, a lint-removing tape 25 wound on the outer wall of the tape roll 24, a winding pressure roller 22 disposed on the outer wall of the first rotating shaft 21, and a servo motor 20 fixed to the outside of one of the vertical plates 19 by a motor base bolt; the output end of the servo motor 20 is connected to one end of the first rotating shaft 21 via a coupling; the free end of the lint-removing tape 25 is fixed to the outer wall of the winding pressure roller 22 by double-sided adhesive; the lower part of the winding pressure roller 22 extends to the bottom of the two vertical plates 19.

[0024] The axes of the first rotating shaft 21 and the second rotating shaft 23 are parallel to the width direction of the support body 1; the tape roll 24 is coaxially fixed to the outer wall of the second rotating shaft 23 by a key connection; the winding pressure roller 22 is coaxially fixed to the outer wall of the first rotating shaft 21 by an interference fit, and the lower part of the winding pressure roller 22 extends 5-15mm below the two vertical plates 19 to ensure full contact with the carpet surface.

[0025] Specifically, the first rotating shaft 21 and the second rotating shaft 23 are staggered and spaced apart. Combined with the positional relationship between the tape roll 24 and the winding pressure roller 22, the lint-removing tape 25 can be released from the tape roll 24 at a stable angle and adhere to the winding pressure roller 22, so as to avoid the lint-removing tape 25 breaking due to excessive pulling or loose adhesion, and to ensure the continuity of lint adhesion.

[0026] This application further proposes that the pressure adaptive adjustment component includes a first cylinder 16, an S-shaped tension / compression sensor 17 connected to the output end of the first cylinder 16, and a mounting side plate 18 connected to the upper side of the pressure sensor 17; the mounting side plate 18 is welded and fixed to the outside of the vertical plate 19 and located below the servo motor 20; the first cylinder 16 is fixed to the upper side of the lifting adjustment mechanism 34 by cylinder seat bolts, its output end is set upward, and the output end is fixedly connected to the lower end of the S-shaped tension / compression sensor 17 by threads; a PLC controller is installed on one side of a side mounting plate 6, and the two pressure sensors 17, the two first cylinders 16, the servo motor 20, the four second cylinders 26, and the negative pressure fan 28 are all electrically connected to the PLC controller.

[0027] The upper end of the S-shaped tension / compression sensor 17 is fastened to the lower center area of ​​the mounting side plate 18 by bolts, ensuring that the axis of the pressure sensor 17 is collinear with the axis of the first cylinder 16, which can accurately detect the contact pressure in the vertical direction.

[0028] Specifically, the first cylinder 16 is coaxially connected to the S-shaped tension and pressure sensor 17, which can directly transmit the adhesion pressure between the lint-removing tape 25 and the carpet. The pressure sensor 17 can collect pressure data in the range of 5-15N in real time and feed it back to the PLC controller. The PLC can drive the first cylinder 16 to extend and retract in real time according to the feedback signal of the pressure sensor 17, quickly correct the adhesion pressure of the lint-removing tape 25, prevent the loose lint from being missed due to insufficient pressure, and prevent the carpet or lint-removing tape 25 from being damaged due to excessive pressure, and adapt to the cleaning needs of carpets of different thicknesses.

[0029] This application further proposes that the lifting adjustment mechanism 34 includes connecting plates 10 respectively disposed on both sides of the support platform body 1, an electric push rod 11 disposed on the upper side of the connecting plate 10, guide rods 13 disposed on the upper side of the connecting plate 10 and respectively located on both sides of the electric push rod 11, a lifting seat 12 disposed at the output end of the electric push rod 11, and linear bearings embedded on both sides of the lifting seat 12 and adapted to the guide rods 13; two sliding sleeves are provided on the mounting side plate 18, and the sliding sleeves are slidably engaged with the corresponding guide rods 13; two first cylinders 16 are respectively installed on the upper side of the two lifting seats 12, and the first cylinders 16 are located between the corresponding two guide rods 13; both electric push rods 11 are electrically connected to the PLC controller.

[0030] The electric push rod 11 is vertically fixed to the upper center of the connecting plate 10 by flange bolts, with its output end facing upward and connected to the lower center area of ​​the lifting seat 12; two guide rods 13 are vertically welded to the upper side of the connecting plate 10 by interference fit, and the axis of the guide rod 13 is parallel to the axis of the electric push rod 11; the inner ring of the linear bearing is slidably fitted with the guide rod 13, limiting the lifting seat 12 to move only in the vertical direction.

[0031] Specifically, the mounting side plate 18, through the cooperation of the sliding sleeve and the guide rod 13, allows the mounting side plate 18 to adjust its height synchronously with the lifting seat 12, and the guide rod 13 restricts the shaking of the mounting side plate 18, ensuring the detection accuracy of the pressure sensor 17 in the pressure adaptive adjustment component, and providing a basis for the stable bonding pressure between the lint tape 25 and the carpet; the electric push rod 11 is electrically connected to the PLC controller, which can realize the synchronous lifting and lowering of the electric push rods 11 on both sides, and can preset the extension and retraction parameters of the electric push rods 11 according to the carpet thickness, flexibly adapting to the processing needs of carpets of different specifications.

[0032] This application further proposes that the preliminary cleaning brush assembly includes a fixing plate 14 detachably connected to one side of the two lifting seats 12 by bolts, and a cleaning brush 15 located between the two fixing plates 14 and above the support body 1; the bristles of the cleaning brush 15 are made of anti-static nylon filaments.

[0033] The two fixing plates 14 are installed at the same height to ensure that their tops are on the same horizontal plane; the cleaning brush 15 is long and narrow, and its handle is fixed to the two fixing plates 14 at opposite inner sides by a snap-fit ​​structure.

[0034] Specifically, the bristles of the cleaning brush 15 are made of anti-static nylon, which can prevent the secondary adsorption of loose hair caused by static electricity generated by friction during the cleaning process, ensuring that the loose hair after pre-cleaning can be adhered by the subsequent lint adhesive tape 25, thus improving the overall cleaning efficiency. In addition, the cleaning brush 15 is located in front of the tape adhesion mechanism 35, which can loosen knotted or stubbornly attached loose hair in advance, laying the foundation for the subsequent adhesion and removal of the lint adhesive tape 25.

[0035] This application further proposes that the transverse drive mechanism 33 includes a lead screw 8 rotatably connected between two side mounting plates 6 and located on one side of the support platform body 1 via ball bearings, a threaded sleeve 9 threadedly engaged with the lead screw 8, a guide rod 30 located between the two side mounting plates 6 and located on the other side of the support platform body 1, a sliding sleeve 31 slidably engaged with the guide rod 30, and a drive motor 7 fixed to one side of one side mounting plate 6 by motor mount bolts; the output end of the drive motor 7 is connected to one end of the lead screw 8; the upper sides of the sliding sleeve 31 and the threaded sleeve 9 are respectively fixed to the lower sides of the two connecting plates 10 by bolts; limit sensors 36 are installed on opposite sides of the two side mounting plates 6, one of the limit sensors 36 is located on the threaded sleeve 9 near the initial end of the drive motor 7, and the other limit sensor 36 is located on the threaded sleeve 9 away from the end of the stroke of the drive motor 7; the drive motor 7 and the two limit sensors 36 are all electrically connected to a PLC controller.

[0036] The lead screw 8 has its axis parallel to the length of the support platform body 1. One end of the lead screw 8 penetrates one of the side mounting plates 6 and is connected to the output end of the drive motor 7 via a coupling. The guide rod 30 is parallel to the lead screw 8, and its two ends are fixed between the two side mounting plates 6 by interference fit. The sliding sleeve 31 is slidably fitted with the guide rod 30 through an internal copper sleeve. The limit sensor 36 on the side closer to the drive motor 7 is fixed to the side of the inner wall of the side mounting plate 6 corresponding to the initial position of the threaded sleeve 9. The limit sensor 36 on the side farther from the drive motor 7 is fixed to the side of the inner wall of the other side mounting plate 6 corresponding to the maximum stroke end point of the threaded sleeve 9, forming a bidirectional limit monitoring of the reciprocating movement of the threaded sleeve 9. When the threaded sleeve 9 moves to trigger either side limit sensor 36, the sensor immediately sends an electrical signal to the PLC controller. After receiving the signal, the controller controls the drive motor 7 to execute a stop or reverse operation command in real time.

[0037] It should be noted that the pressure sensor 17, the first cylinder 16, the servo motor 20, the second cylinder 26, the negative pressure fan 28, the drive motor 7, the electric push rod 11, the PLC and controller, etc. are all commercially available and mature products that can be purchased directly. Their specific models and specifications can be selected according to the actual application scenario. The staff does not need to understand the specific structure and working principle of these components. As long as the purchased products can operate normally, it will not affect the specific implementation of this utility model. Therefore, they will not be described in detail here.

[0038] Working process and principle: When the carpet lint removal device is running, the carpet to be treated is first laid flat on the support body 1 of the workbench 32. Then, the PLC controller starts four second cylinders 26 to drive the silicone pressure blocks 27 to descend, so that the pressure blocks 27 are embedded in the corresponding pressure grooves 3, forming a flexible pressing on both sides of the carpet (the arc-shaped chamfer design avoids damage to the carpet edges). At the same time, the negative pressure fan 28 is started, and a negative pressure is formed in the negative pressure adsorption chamber 4 through the air pipe 29. The matrix openings 5 ​​on the upper side of the support body 1 generate uniform adsorption force, fixing the middle of the carpet. This achieves a dual fixing effect of edge pressing and middle adsorption, preventing the carpet from shifting or wrinkling during subsequent cleaning.

[0039] After fixing, the PLC controller controls the two electric push rods 11 to extend and retract synchronously according to the preset parameters of the thickness of the carpet to be treated, so that the lifting seat 12 can be smoothly raised and lowered along the guide rod 13 until the bristles of the cleaning brush 15 of the fixed brush cleaning component lightly touch the carpet surface, and the lint-removing tape 25 on the winding pressure roller 22 of the tape wrapping lint removal mechanism 35 forms a 5-15N adhesion pressure with the carpet surface, thus completing the parameter calibration before cleaning.

[0040] Subsequently, the PLC controller synchronously drives the drive motor 7 of the horizontal drive mechanism 33 and the servo motor 20 of the tape-wrapping lint removal mechanism 35 to start. The drive motor 7 drives the lead screw 8 to rotate, causing the threaded sleeve 9, which is threaded with the lead screw 8, to translate along the axis of the lead screw 8. Simultaneously, it drives the sliding sleeve 31, which is slidably engaged with the guide rod 30, to slide in the same direction as the guide rod 30. This, in turn, drives the entire lifting adjustment mechanism 34, the pressure adaptive adjustment component, and the lint removal related components to move at a constant speed along the length of the support platform body 1. During the movement, the cleaning brush 15 of the fixed brush-type cleaning component... First, the carpet surface is initially brushed. Then, the bristles of the cleaning brush 15 penetrate deep into the carpet pile layer to comb and loosen stubborn loose hairs with strong adhesion. Next, the servo motor 20 drives the first rotating shaft 21 to rotate the winding pressure roller 22 at a low speed. The tape roll 24 on the second rotating shaft 23 releases the lint-adhesive tape 25 synchronously with the rotation of the winding pressure roller 22. The adhesive side of the lint-adhesive tape 25 faces outward and is tightly adhered to the carpet surface to adhere the pre-combed loose hairs. The winding pressure roller 22 continues to rotate, so that the tape segment with loose hairs is continuously wrapped around the roller body, realizing the continuous collection and removal of loose hairs. During this process, the S-shaped tension and pressure sensor 17 of the pressure adaptive adjustment component monitors the adhesion pressure between the lint-removing tape 25 and the carpet surface in real time. If the detected pressure exceeds the preset range of 5-15N (too tight or too loose), the PLC controller immediately drives the first cylinder 16 to extend and retract for fine adjustment. The mounting side plate 18 slides synchronously along the guide rod 13 with the sliding sleeve to correct the adhesion pressure to the optimal range, ensuring that the lint removal effect is achieved and the carpet surface is not damaged.

[0041] When the threaded sleeve 9 moves with the lead screw 8 to the limit sensor 36 at the end of the stroke away from the drive motor 7, the limit sensor 36 triggers a signal and transmits it to the PLC controller. The PLC controller then controls the drive motor 7 to rotate in the opposite direction, the servo motor 20 to stop running, and the two electric push rods 11 to rise synchronously, driving the lifting seat 12 to rise along the guide rod 13, so that the cleaning brush 15 is removed from the carpet surface and the lint-removing tape 25 on the pressure roller 22 is separated from the carpet surface. Subsequently, the threaded sleeve 9 moves in the opposite direction along the lead screw 8, synchronously driving the sliding sleeve 31 to slide in the opposite direction along the guide rod 30. When the sliding sleeve 31 moves to the limit sensor 36 near the initial end of the drive motor 7, the limit sensor 36 triggers a signal, the PLC controller controls the drive motor 7 to stop running, the negative pressure fan 28 to stop working (the negative pressure adsorption chamber 4 is released from negative pressure), and the four second cylinders 26 synchronously drive the pressure block 27 to extend upward from the pressure groove 3. The operator can then remove the cleaned carpet, replace the tape roll 24, and the equipment is reset to the initial state, waiting to enter the next round of lint cleaning operation.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
