Description

Technical Field

[0001] This invention belongs to the field of fabric flocking technology, specifically relating to a graphene fabric flocking machine. Background Technology

[0002] The principle of electrostatic flocking is to utilize the physical property that like charges repel and unlike charges attract. The flock fibers are made to carry a negative charge. When the object to be flocked is placed under zero potential or grounded conditions, the flock fibers are attracted by the opposite potential of the plant body and rise vertically to the surface of the object to be flocked. Since the plant body is coated with adhesive, the flock fibers are vertically adhered to the plant body. Electrostatic flocking is a new production process that utilizes the natural properties of electric charge.

[0003] Electrostatic flocking is a method for rapidly obtaining graphene conductive fabrics by implanting graphene fibers with one negatively charged end into the surface of a fabric to form a conductive layer. For example, publication number CN109295745B is entitled "A Method for Preparing Flexible and Durable Conductive Graphene Fabrics by Electrostatic Flocking".

[0004] However, this method uses a flocking machine, which has the problem that the flocking fibers cannot be fully utilized during use. The unused fibers not only adhere to the fabric and are carried away with the fabric, which can easily lead to waste of the fibers, but also pollute the on-site working environment. Summary of the Invention

[0005] The purpose of this invention is to provide a graphene fabric flocking machine in order to solve the problems mentioned in the background art.

[0006] The present invention achieves the above objectives through the following technical solutions: A graphene fabric flocking machine includes a base, on which a rotating ring is rotatably mounted, and a drive assembly for driving the rotating ring to rotate is provided on the base. The inner ring of the rotating ring is fixedly provided with a plurality of base plates for placing fabric along its circumference, and each of the four corners of the base plate is provided with a clamping component. A mounting frame is fixedly provided on the base, and a flocking machine body is fixedly provided on the mounting frame. A nozzle is connected to the flocking machine body, and a collection box is fixedly provided on the mounting frame. The nozzle is located in the middle of the collection box. When the substrate rotates to the top of the rotating ring, the nozzle performs electrostatic flocking on the inverted fabric on the substrate.

[0007] Preferably, the drive assembly includes a drive motor fixedly mounted on the base and two rotating shafts rotatably mounted on the base; One of the rotating shafts is provided with a transmission component between it and the output shaft of the drive motor, and the rotating shaft rotates synchronously with the drive motor. Both of the aforementioned rotating shafts are concentrically fixed with several rotating wheels for positioning and supporting the rotating ring. The rotating wheels drive the rotating ring to rotate as the rotating shafts rotate.

[0008] Preferably, the outer ring of the rotating ring is provided with a plurality of annular grooves corresponding one-to-one with the rotating wheel, the rotating wheel is located in the annular groove, and the rotating wheel is used to limit the rotation of the rotating ring.

[0009] Preferably, the four corners of the substrate are provided with through holes perpendicular to its plane. The clamping assembly includes four connecting rods that are movably installed at each of the through holes. Each of the four connecting rods is fixed with a clamping plate for fixing the fabric at one end near the center of the rotating ring. A return spring is provided between the clamping plate and the substrate. The return spring does not extend or retract when the clamping plate is in contact with the substrate, and it is stretched when the clamping plate moves away from the substrate.

[0010] Preferably, the four corners of the substrate are notched, and slots are provided at the notched corners. A pin is movably installed in the slot, and a slider is fixedly installed in the pin. The slider has a through hole perpendicular to the plane of the substrate. The clamping assembly includes four connecting rods that are movably installed at each through hole. Each of the four connecting rods has a clamping plate fixed at one end near the center of the rotating ring for fixing the fabric. A return spring is provided between the clamping plate and the slider. When the clamping plate is in contact with the slider, the return spring does not extend or retract. When the clamping plate moves away from the slider, the return spring is stretched.

[0011] Preferably, electromagnets are fixedly installed at all four corners of the substrate. When the electromagnets are turned on, the slider generates a magnetic attraction force, causing the slider to approach the substrate. When the electromagnets are turned off, there is no interaction force between the slider and the substrate.

[0012] Preferably, the base is provided with two boss groups, each boss group including two bosses that are fixedly fixed on the base in sequence according to the rotation direction of the rotating ring. The four bosses correspond to the connecting rods at the four corners of the substrate. When the connecting rods move to the base, they contact the bosses and move, causing the clamping plate to move away from the substrate. After the connecting rods disengage from the bosses, the return spring drives the clamping plate to move closer to the substrate.

[0013] The beneficial effects of this invention are as follows: This invention inverts the fabric and uses static electricity to move the pile upwards, unlike the traditional downward flocking method. This allows the pile that is not in contact with the adhesive on the fabric and the pile floating in the air to move downwards under their own gravity and be collected, reducing the waste rate of pile. The collection of pile does not affect the normal movement of the fabric.

[0014] This invention enables continuous flocking of fabrics, thereby improving the efficiency of fabric flocking.

[0015] This invention can shake the fabric after flocking to further shake off the lint adhering to the fabric surface, which not only makes the fabric surface cleaner, but also increases the lint recovery efficiency.

[0016] This invention can automatically clamp and release fabrics, making the fabric loading and unloading process simpler and reducing manual operation. Attached Figure Description

[0019] The present application will now be described in further detail. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example 1 like Figure 1-4 As shown, a graphene fabric flocking machine includes a base 1, and a drive assembly is provided on the base 1. The drive assembly includes a drive motor 8 fixedly mounted on the base 1 and two rotating shafts 9 rotatably mounted on the base 1.

[0021] A transmission component 10 is provided between one of the rotating shafts 9 and the output shaft of the drive motor 8, and the rotating shaft 9 rotates synchronously with the drive motor 8. The transmission component 10 can be a synchronous belt.

[0022] Several rotating wheels 11 are concentrically fixed on both rotating shafts 9.

[0023] A rotating ring 2 is rotatably mounted on the base 1. A rotating wheel 11 is in contact with the outer ring of the rotating ring 2, and two rotating shafts 9 are located on both sides of the rotating ring 2. The rotating wheels 11 on the two rotating shafts 9 suspend the rotating ring 2 in the air. The rotating wheels 11 are used to position and support the rotating ring 2. The rotating wheels 11 rotate with the rotating shafts 9 and drive the rotating ring 2 to rotate.

[0024] The inner ring 2 has several substrates 3 fixedly arranged around its circumference for placing graphene fabric, and each of the four corners of the substrate 3 is provided with a clamping component. The substrate 3 is preferably a flat plate, but is not limited to a flat plate.

[0025] A mounting bracket 4 is fixedly mounted on the base 1. A flocking machine body 5 is fixedly mounted on the mounting bracket 4. A nozzle 6 is connected to the flocking machine body 5. A collection box 7 is fixedly mounted on the mounting bracket 4. The nozzle 6 is located in the middle of the collection box 7 and the working direction of the nozzle 6 is upward.

[0026] It should be noted that after the fabric to be flocked is coated with adhesive, it is laid flat on the substrate 3. The four corners of the fabric are held in place by the clamping assembly, and then the drive motor 8 is started, driving the transmission component 10 to rotate. The substrate 3 or the fabric can be grounded. The transmission component 10 drives the connected rotating shaft 9 to rotate, causing the rotating wheel 11 on the shaft 9 to rotate. The rotating wheel 11, through friction with the rotating ring 2, drives the rotating ring 2 to rotate, causing the substrate 3 to carry the fabric upwards. The substrate 3 stops rotating or its speed decreases when it reaches the top of the rotating ring 2. The flocking machine body 5 generates static electricity, causing the graphene fluff inside the nozzle 6 to become statically charged. At this point, the fluff flies at high speed onto the fabric. Since the object to be flocked has been coated with adhesive according to the process, the flocking is now applied to the adhesive-coated surface.

[0027] After a single flocking process is completed, excess fluff on the fabric and fluff floating in the air fall into collection box 7 under the influence of gravity. Once a certain amount of fluff accumulates in collection box 7, it is processed in a centralized manner.

[0028] In the above embodiment, the four corners of the substrate 3 are provided with through holes 13 perpendicular to its plane. The clamping assembly includes four connecting rods 14 that are movably installed at each of the through holes 13. Each of the four connecting rods 14 is fixed with a clamping plate 15 for fixing the fabric at one end near the center of the rotating ring 2. A return spring 16 is provided between the clamping plate 15 and the substrate 3. When the clamping plate 15 is in contact with the substrate 3, the return spring 16 does not extend or retract. When the clamping plate 15 is away from the substrate 3, the return spring 16 is stretched.

[0029] It should be noted that when clamping the fabric, the clamping plate 15 is engaged, causing it to move away from the substrate 3. At this time, the return spring 16 is stretched and has a restoring force. After the fabric is laid on the substrate 3, the clamping plate 15 is released, and the return spring 16 moves the clamping plate 15 closer to the substrate 3, clamping and fixing the fabric on the substrate 3.

[0030] Furthermore, the outer ring of the rotating ring 2 is provided with several annular grooves 12 that correspond one-to-one with the rotating wheel 11. The rotating wheel 11 is located in the annular groove 12 and is used to prevent the rotating ring 2 from falling to the ground from the rotating wheel 11.

[0031] Example 2 like Figure 1-4 As shown, unlike Embodiment 1, the substrate 3 has notches 17 at its four corners, and slots 18 are provided at the notches 17. A pin 19 is movably installed in the slot 18, and a slider 20 is fixedly installed in the pin 19. The slots 18 are installed at an angle, so when the substrate 3 moves to the top of the conversion, the slider 20 moves diagonally downwards. The end of the pin 19 inside the slot 18 is larger to prevent the pin 19 from accidentally sliding out of the slot 18. The position of the slider 20 can also be restricted by fixing a connecting wire between the slider 20 and the substrate 3.

[0032] The slider 20 has a through hole 13 perpendicular to the plane of the substrate 3. The clamping assembly includes four connecting rods 14 that are movably installed at each of the through holes 13. Each of the four connecting rods 14 has a clamping plate 15 fixed at one end near the center of the rotating ring 2 for fixing the fabric. A return spring 16 is provided between the clamping plate 15 and the slider 20. When the clamping plate 15 is in contact with the slider 20, the return spring 16 does not extend or retract. When the clamping plate 15 moves away from the slider 20, the return spring 16 is stretched.

[0033] It should be noted that because the fabric is located below the substrate 3 during flocking, the fabric may deform downwards due to gravity. This deformation, especially when the fabric is large, can make the fabric surface uneven, thus affecting the flocking effect. By providing pins 19 and sliders 20, when slider 20 moves diagonally downwards, the distance between the four sliders 20 increases, causing the fabric to be pulled in four different directions, resulting in a smoother fabric and improving the flocking effect. When slider 20 moves to the bottom position of the rotating ring 2, it re-contacts the substrate 3 under gravity.

[0034] Furthermore, electromagnets 21 are fixedly mounted at each of the four corners of the substrate 3. When the electromagnets 21 are activated, they generate a magnetic attraction to the iron slider 20, causing the slider 20 to approach the substrate 3. Then, when the energization of the electromagnets 21 is stopped, the magnetic attraction disappears, causing the slider 20 to abruptly separate from the substrate 3. The repeated pulling of the fabric by the slider 20 shakes off excess graphene fibers, simplifying the post-processing of the fabric and resulting in a greater amount of recovered graphene fibers.

[0035] Furthermore, the base 1 is provided with two boss groups, each boss group including two bosses 22 that are fixedly fixed on the base 1 in the direction of rotation of the rotating ring 2. The four bosses 22 correspond to the connecting rods 14 at the four corners of the substrate 3. When the connecting rods 14 move to the base 1, they contact the bosses 22 and move, causing the clamping plate 15 to move away from the substrate 3. At this time, the fabric can be removed or placed without manually lifting the clamping plate 15. After the connecting rods 14 disengage from the bosses 22, the return spring 16 drives the clamping plate 15 to move back closer to the substrate 3. To prevent the slider 20 from moving simultaneously with the connecting rods 14, the slider 20 can be limited by the electromagnet 21.

[0036] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
