Description

Technical Field

[0001] This application relates to the field of carpet production technology, and in particular to a coating device for tufted carpets. Background Technology

[0002] In the production of tufted carpets, coating equipment is used to evenly coat the surface of the base fabric with adhesives and other materials to enhance the bonding strength between the base fabric and the pile layer, thereby improving the carpet's abrasion resistance and other properties.

[0003] Existing coating equipment includes a base fabric roller and an adhesive applicator. The base fabric roller needs to continuously feed the base fabric during the coating process, and the adhesive applicator applies the adhesive to the base fabric. During production, when a roll of base fabric is used up, a new base fabric roller needs to be replaced in time to ensure the continuity of production.

[0004] However, the replacement of the base fabric roller currently relies mainly on manual operation. When the base fabric on the roller is exhausted, the worker needs to lift the empty base fabric roller off the frame first, and then lift the fully loaded base fabric roller with the new base fabric and place it in the installation position on the frame. This replacement method is time-consuming and labor-intensive, which prolongs the replacement time of the base fabric roller and reduces the replacement efficiency of the base fabric roller, thus affecting the continuous operation efficiency of the coating equipment, which has obvious shortcomings. Utility Model Content

[0005] To improve the efficiency of workers changing base fabric rollers, this application provides a coating device for tufted carpets.

[0006] The coating equipment for tufted carpets provided in this application adopts the following technical solution:

[0007] A coating device for tufted carpets includes a frame, on which a motor is mounted. The output shaft of the motor is detachably connected to a base fabric roller via a coupling. An auxiliary assembly is mounted on the frame, including a rotating shaft rotatably connected to the frame. Roller frames are mounted on opposite sides of the rotating shaft, and both ends of the base fabric roller are located inside the roller frames. The roller frames have openings. A drive component is mounted on the frame to drive the roller frames to rotate about the axis of the rotating shaft.

[0008] By adopting the above technical solution, during replacement, the connection between the coupling and the unloaded base fabric roller is first disconnected. Then, the drive unit drives the roller holder frame to rotate towards the ground and tilt downwards. At this time, the opening is close to the ground, and the unloaded base fabric roller rolls to the opening under gravity. The worker takes out the unloaded base fabric roller and places the full-loaded base fabric roller in it. After placement, the drive unit drives the roller holder frame to rotate upwards and tilt upwards. At this time, the full-loaded base fabric roller rolls to the end of the roller holder frame under gravity. The worker connects the coupling to the full-loaded base fabric roller, thus completing the replacement of the base fabric roller. The auxiliary components reduce the height at which the worker can raise the base fabric roller, and the base fabric roller rolls in the roller holder frame under its own gravity, saving time and effort, thereby improving the efficiency of the worker in replacing the base fabric roller.

[0009] Optionally, the driving component is a driving cylinder rotatably connected to the frame, and the driving cylinder is arranged in a one-to-one correspondence with the two roller frames, and the piston rod of the driving cylinder is hinged to the corresponding roller frame.

[0010] By adopting the above technical solution, during replacement, the piston rods of the two drive cylinders retract synchronously, pulling the roller frame to rotate to a downward tilted state. After the fully loaded base fabric roller is placed, the piston rods of the two drive cylinders extend synchronously, pushing the roller frame to rotate to an upward tilted state. The two drive cylinders ensure that the roller frame is subjected to balanced force and has a consistent tilt angle, reducing the possibility of the base fabric roller shifting or getting stuck due to the height difference on both sides.

[0011] Optionally, a limiting block is provided on the outer surface of the rotating shaft, and an arc groove is provided on the inner side wall of the frame to slide with the limiting block. When the limiting block moves to the end of the arc groove, the roller frame tilts upward, and the axis of the base fabric roller is in the same straight line as the axis of the motor output shaft.

[0012] By adopting the above technical solution, during the rotation of the roller frame, the limiting block slides inside the arc groove. The length of the arc groove limits the rotation range of the roller frame, thereby avoiding the need for multiple adjustments due to the roller frame not rotating into position. This ensures a smooth connection between the coupling and the base fabric roller, further improving the efficiency of workers changing the base fabric roller.

[0013] Optionally, the roller frame has a limiting groove along its length, and the two opposite base fabric rollers are rotatably connected to limiting wheels. The limiting wheels are nested on the base fabric rollers and are tumbled within the limiting grooves.

[0014] By adopting the above technical solution, the limiting wheel transforms sliding friction into rolling friction, reducing the friction between the base fabric roller and the roller frame, making the movement of the base fabric roller smoother. The opening of the limiting groove effectively restricts the movement direction of the limiting wheel, reducing the occurrence of axial displacement when the base fabric roller moves, thereby ensuring the smooth connection between the coupling and the base fabric roller.

[0015] Optionally, each of the roller frames is provided with a limiting element, which is a limiting pin. The roller frame is provided with a sliding groove that slides with the limiting pin, and the limiting wheel is provided with an insertion groove that inserts with the limiting pin. When the base fabric roller is connected to the coupling, the insertion groove and the sliding groove are aligned. The inner sidewall of the sliding groove is provided with a receiving groove, and a control component that drives the limiting pin to insert into or disengage from the insertion groove is provided in the receiving groove.

[0016] By adopting the above technical solution, after the base fabric roller is connected to the coupling, the control component drives the limiting pin to be inserted into the insertion groove through the sliding groove, thus fixing the position of the limiting wheel in the roller frame. By fixing the two limiting wheels, the two ends of the base fabric roller are constrained, reducing the possibility of the base fabric roller moving due to unidirectional driving force or equipment vibration during equipment operation, and ensuring the accuracy of coating. When changing, the control component drives the limiting pin to disengage from the insertion groove, at which time the limiting wheel can roll freely in the roller frame.

[0017] Optionally, the control component includes an iron block slidably connected in the receiving groove, the iron block being disposed at the end of the limiting pin, an electromagnetic ring for adsorbing the iron block being disposed at one end of the receiving groove near the sliding groove, and a return spring being disposed at the other end, the end of the return spring away from the receiving groove being disposed on the iron block, in the natural state of the return spring, the limiting pin being disengaged from the insertion groove, and when the electromagnetic ring is energized to adsorb the iron block, the limiting pin being inserted into the insertion groove.

[0018] By adopting the above technical solution, after the base fabric roller is connected to the coupling, the electromagnetic ring is energized to attract the iron block, and the iron block drives the limit pin to insert into the insertion groove, thus locking the base fabric roller. When replacing, the electromagnetic ring is de-energized, at which time the attraction force of the electromagnetic ring on the iron block disappears, the return spring rebounds and drives the iron block to reset, the limit pin disengages from the insertion groove, and the base fabric roller is released.

[0019] Optionally, two limiting members are provided on each of the roller frames, and the two limiting members are respectively provided on both radial sides of the limiting wheel.

[0020] By adopting the above technical solution, the two limiting pins achieve bidirectional constraint on the limiting wheel, making the fixing of the limiting wheel in the roller frame more secure, thereby making the rotation of the base fabric roller more stable.

[0021] Optionally, each of the roller frames is hinged to two arc-shaped clamps at its end. The two arc-shaped clamps are arranged opposite each other and sleeved on the outer surface of the rotating shaft. The two arc-shaped clamps are detachably connected by connecting bolts.

[0022] By adopting the above technical solution, when it is necessary to disassemble the roller frame, the worker loosens the connecting bolts to separate the two arc-shaped clamps from each other. At this time, the connection between the roller frame and the rotating shaft disappears, and the worker can replace the roller frame. During installation, the two arc-shaped clamps are placed on the outer surface of the rotating shaft and the loose connecting bolts are tightened. This achieves a detachable connection between the roller frame and the rotating shaft, which makes it convenient for workers to replace the roller frame when it is damaged.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The embodiments of this application provide an auxiliary component, which reduces the height at which the worker can raise the base fabric roller, and the base fabric roller rolls within the roller frame under its own weight, saving time and effort, thereby improving the efficiency of the worker in changing the base fabric roller.

[0025] 2. In this embodiment of the application, by setting a limiting wheel and a limiting groove, the setting of the limiting wheel and the limiting groove effectively restricts the movement direction of the limiting wheel, reduces the axial displacement when the base fabric roller moves, and thus ensures the smooth connection between the coupling and the base fabric roller;

[0026] 3. In this embodiment of the application, by setting up a control component and a limiting component, after the base fabric roller is connected to the coupling, the control component drives the limiting pin to be inserted into the insertion groove through the sliding groove, thereby fixing the position of the limiting wheel in the roller frame. By fixing the two limiting wheels, the two ends of the base fabric roller are constrained, reducing the possibility of the base fabric roller moving due to unidirectional driving force or equipment vibration during equipment operation, and ensuring the accuracy of coating.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a coating apparatus for tufted carpets.

[0034] Reference Figure 1 and Figure 2 A coating device for tufted carpets includes a frame 1, which is mounted on a gluing device. A motor 2 is fixedly installed on the frame 1. The output shaft of the motor 2 is detachably connected to a base fabric roller 3 via a coupling 21. A base fabric is wound on the base fabric roller 3. During gluing, the power of the motor 2 is transmitted to the base fabric roller 3 via the coupling 21 to drive it to rotate. When the base fabric roller 3 rotates, it conveys the base fabric to achieve gluing.

[0035] Reference Figure 1 and Figure 2 The frame 1 is provided with an auxiliary component 4. Specifically, the auxiliary component 4 includes a rotating shaft 41 rotatably connected to the end of the frame 1. Roller frames 42 are installed on both sides of the rotating shaft 41 along the axial direction. Both ends of the base fabric roller 3 are set inside the roller frames 42. An opening 421 is opened on the side of the roller frames 42 away from the rotating shaft 41. The frame 1 is provided with a driving component 43 corresponding to the two roller frames 42. The driving component 43 is a driving cylinder rotatably connected to the inner wall of the frame 1. The piston rod of the driving cylinder is hinged to the bottom surface of the corresponding roller frame 42.

[0036] Reference Figure 1 and Figure 2 A limiting block 411 is fixedly connected to the outer surface of the rotating shaft 41. An arc groove 101 that slides with the limiting block 411 is provided on the inner side wall of the frame 1. When the roller frame 42 rotates, the limiting block 411 slides inside the arc groove 101. When the limiting block 411 moves to the end of the arc groove 101 near the ground, the roller frame 42 is tilted downward and the opening 421 is close to the ground. When the limiting block 411 moves to the end of the arc groove 101 away from the ground, the roller frame 42 is tilted upward, and at this time the axis of the base fabric roller 3 and the axis of the output shaft of the motor 2 are on the same straight line.

[0037] When the base fabric roller 3 needs to be replaced, the worker first disconnects the coupling 21 from the unloaded base fabric roller 3. Then, the piston rods of the two drive cylinders retract synchronously, pulling the roller frame 42 and the rotating shaft 41 to rotate towards the ground. When the rotating shaft 41 moves the limiting block 411 to the end of the arc groove 101 near the ground, the roller frame 42 is tilted downward and the opening 421 is close to the ground. The unloaded base fabric roller 3 rolls to the opening 421 under the action of gravity. The worker takes out the unloaded base fabric roller 3 and places the fully loaded base fabric roller 3 in its place.

[0038] After placement, the piston rods of the two drive cylinders extend synchronously, pushing the roller frame 42 and the rotating shaft 41 to rotate upward. When the limiting block 411 moves to the end of the arc groove 101 away from the ground, it rotates to an inclined upward state. At this time, the fully loaded base fabric roller 3 rolls to the end of the roller frame 42 under gravity. The worker connects the coupling 21 to the fully loaded base fabric roller 3, thus completing the replacement of the base fabric roller 3. The auxiliary component 4 makes it easier for the worker to raise the base fabric roller 3. The base fabric roller 3 rolls in the roller frame 42 by its own gravity, saving time and effort, thereby improving the efficiency of the worker in replacing the base fabric roller 3.

[0039] Reference Figure 2 and Figure 3 Each roller frame 42 has two arc-shaped clamps 5 hinged to its end near the rotating shaft 41. The two arc-shaped clamps 5 are arranged opposite each other and sleeved on the outer surface of the rotating shaft 41. The ends of the two arc-shaped clamps 5 away from the roller frame 42 are detachably connected by connecting bolts 51. In order to reduce the possibility of slippage and relative rotation between the arc-shaped clamps 5 and the rotating shaft 41, rubber strips (not shown in the figure) can be fixedly connected to the inner surfaces of the two arc-shaped clamps 5. The rubber strips are parallel to the axis of the rotating shaft 41, and the rotating shaft 41 has grooves for the rubber strips to be inserted (not shown in the figure).

[0040] When the roller frame 42 needs to be disassembled, the worker loosens the connecting bolt 51 to make the connection between the two arc-shaped clamps 5 disappear. Then, the two arc-shaped clamps 5 are rotated to separate them. At this time, the connection between the roller frame 42 and the rotating shaft 41 is lost, and the worker can replace the roller frame 42. During installation, the two arc-shaped clamps 5 are rotated to abut against the outer surface of the rotating shaft 41. At this time, the rubber strip is embedded in the groove. Finally, the connecting bolt 51 is tightened. In this way, the roller frame 42 and the rotating shaft 41 are detachably connected, which makes it convenient for the worker to replace the roller frame 42 when it is damaged.

[0041] Reference Figure 2 and Figure 3 Each roller frame 42 has a limiting groove 422 on its inner sidewall along its length. The base fabric roller 3 is rotatably fitted with limiting wheels 31 on its opposite sides. The limiting wheels 31 are nested on the base fabric roller 3 and are rolled inside the limiting groove 422. The limiting wheels 31 reduce the friction between the base fabric roller 3 and the roller frame 42, making the movement of the base fabric roller 3 smoother. At the same time, the limiting groove 422 restricts the movement direction of the limiting wheels 31, reducing the possibility of axial displacement when the base fabric roller 3 moves.

[0042] Reference Figure 3 and Figure 4Each roller frame 42 has a sliding groove 6 on its inner sidewall. The sliding groove 6 is connected to the limiting groove. The two sliding grooves 6 are respectively located on the radial sides of the base fabric roller 3. The sliding groove 6 is slidably connected to the limiting pin 7. The outer sidewall of the limiting wheel 31 has an insertion groove 311 that is engaged with the limiting pin 7. When the base fabric roller 3 is connected to the coupling 21, the insertion groove 311 and the sliding groove 6 are facing each other.

[0043] Reference Figure 3 and Figure 4 Each sliding groove 6 has an inner wall with a receiving groove 61. The cross-section of the receiving groove 61 and the sliding groove 6 forms a T-shape. A control component 8 is provided in the receiving groove 61. Specifically, the control component 8 includes an iron block 81 that is slidably connected in the receiving groove 61. The iron block 81 is fixedly connected to the end of the limiting pin 7 that extends to the receiving groove 61. An electromagnetic ring 82 is fixedly connected to the end wall of the receiving groove 61 near the sliding groove 6, and a return spring 83 is fixedly connected to the other end. The end of the return spring 83 away from the receiving groove 61 is fixedly connected to the iron block 81. In its natural state, the limiting pin 7 is disengaged from the insertion groove 311. When the electromagnetic ring 82 is energized and attracts the iron block 81, the limiting pin 7 is inserted into the insertion groove 311.

[0044] When the base fabric roller 3 is connected to the coupling 21, the electromagnetic ring 82 is energized and generates an adsorption force on the iron block 81. The iron block 81 overcomes the elastic force of the return spring 83 and drives the limit pin 7 to insert into the insertion slot 311. In this way, the position of the limit wheel 31 in the roller frame 42 is fixed. By fixing the two limit wheels 31, the two ends of the base fabric roller 3 are constrained, reducing the possibility of the base fabric roller 3 moving due to unidirectional driving force or equipment vibration during equipment operation, thus ensuring the accuracy of coating.

[0045] When replacing, the electromagnetic ring 82 is de-energized. At this time, the attraction force of the electromagnetic ring 82 on the iron block 81 disappears, the return spring 83 rebounds and drives the iron block 81 to reset, the limit pin 7 disengages from the insertion groove 311, and the limit wheel 31 can roll freely in the roller frame 42.

[0046] The implementation principle of a coating device for tufted carpets according to an embodiment of this application is as follows: When it is necessary to replace the base fabric roller 3, the worker first disconnects the coupling 21 from the unloaded base fabric roller 3. Then, the piston rods of the two drive cylinders retract synchronously, pulling the roller frame 42 and the rotating shaft 41 to rotate towards the ground. When the rotating shaft 41 drives the limiting block 411 to the end of the arc groove 101 near the ground, the roller frame 42 is tilted downward and the opening 421 is close to the ground. The unloaded base fabric roller 3 rolls to the opening 421 under the action of gravity. The worker takes out the unloaded base fabric roller 3 and places the fully loaded base fabric roller 3.

[0047] After placement, the piston rods of the two drive cylinders extend synchronously, pushing the roller frame 42 and the rotating shaft 41 to rotate upward. When the limiting block 411 moves to the end of the arc groove 101 away from the ground, it rotates to an inclined upward state. At this time, the fully loaded base fabric roller 3 rolls to the end of the roller frame 42 under gravity. The worker connects the coupling 21 to the fully loaded base fabric roller 3, thus completing the replacement of the base fabric roller 3. The auxiliary component 4 makes it easier for the worker to raise the base fabric roller 3. The base fabric roller 3 rolls in the roller frame 42 by its own gravity, saving time and effort, thereby improving the efficiency of the worker in replacing the base fabric roller 3.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
