Description

Technical Field

[0001] This invention belongs to the field of glass fiber cotton winding technology, and relates to a glass fiber cotton winding device and method. Background Technology

[0002] Chinese patent CN219620558U discloses a glass fiber cotton winding device, which includes two opposing support plates, several rollers rotatably connected between the two support plates, and a motor for driving the rollers to rotate. The rollers are circumferentially distributed and form an inner cavity of the roll. An inlet communicating with the inner cavity of the roll is formed between two adjacent rollers. One support plate is provided with an outlet, and the other support plate is provided with a pushing mechanism that pushes the glass fiber cotton roll out.

[0003] Fiberglass wool enters the roll cavity through the feed inlet. As multiple rollers rotate, the fiberglass wool is gradually rolled into a roll, and then pushed out through the discharge outlet by a pushing mechanism. However, in actual use, due to the relatively large width of the feed inlet, such as... Figure 1 As shown, when the very front end of the cotton roll moves from top to bottom to the feed inlet, it will press against the glass fiber cotton that has not entered the inner cavity of the roll, which can easily cause the winding to fail and requires manual intervention. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a glass fiber cotton winding device and method that does not cause cotton roll winding failure.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A fiberglass wool winding device includes two opposing support plates, several rollers rotatably disposed between the two support plates, and a power assembly for driving the rollers to rotate synchronously and in the same direction. The rollers are parallel to each other and arranged in a ring, forming a winding cavity. One side of the winding cavity has a feed inlet. One support plate has a discharge outlet communicating with the winding cavity. The diameter of the discharge outlet is larger than the inner diameter of the winding cavity. The other support plate has a pushing assembly for pushing the fiberglass wool roll located in the winding cavity out of the discharge outlet. A guide is provided at the feed inlet, which can guide the front end of the fiberglass wool downward to the inside of the fiberglass wool located at the feed inlet.

[0007] Like cotton quilts, fiberglass wool is long and thin. Its front end enters the roll chamber through the feed inlet and moves downward under gravity until it comes into contact with the roller below it. The rotating roller feeds the fiberglass wool forward along the inner wall of the roll chamber until the front end of the fiberglass wool is guided by the guide to extend to the inside of the fiberglass wool, thus preventing roll failure.

[0008] In the above-mentioned glass fiber cotton winding device, the guide includes a guide roller disposed between two support plates. The guide roller is parallel to the winding roller. The guide roller is located above the feed inlet and partially extends into the winding cavity. The horizontal distance from the winding roller located below the feed inlet to the center line of the winding cavity is less than the horizontal distance from the guide roller to the center line of the winding cavity.

[0009] This is equivalent to using guide rollers to fold the front end of the downward-extending glass fiber cotton inward at a certain angle. In addition to guide rollers, guide plates, guide rods, and other structures can also be used, as long as they can guide the front end of the glass fiber cotton to the inside of the glass fiber cotton.

[0010] In the aforementioned glass fiber wool winding device, the guide roller is rotatably configured. A rotatably configured guide roller provides better guidance for the glass fiber wool.

[0011] In the aforementioned glass fiber cotton winding device, horizontally extending guide rails are fixed on both support plates. The two guide rails are arranged opposite each other, and a plurality of conveying rollers are installed between the two guide rails. The plurality of conveying rollers are located at the same height, and the height of the winding roller located below the feed inlet is not higher than the height of the conveying rollers. The plurality of conveying rollers are connected by chain and sprocket transmission, so that the plurality of conveying rollers can rotate synchronously and in the same direction, and are driven by the same geared motor, thereby achieving the purpose of conveying glass fiber cotton.

[0012] In the aforementioned glass fiber cotton winding device, a plurality of horizontally extending guide rods are provided on the outer side of the support plate with the discharge port. The guide rods are evenly distributed around the discharge port, and the outer diameter of the guide channel formed by the plurality of guide rods is not less than the diameter of the discharge port.

[0013] The length of the guide rod should be greater than the length of the cotton roll. After the cotton roll is pushed out of the outlet, it will enter the guide channel formed by several guide rods. At this time, the nylon bag / plastic bag is put over the multiple guide rods, and the cotton roll can be directly put into the nylon bag / plastic bag.

[0014] In the aforementioned glass fiber cotton winding device, the power component includes a driven gear, a driving gear, and a drive motor coaxially fixed on the winding roller. The driving gear is driven by the drive motor, and a transmission gear meshes with each of the two adjacent driven gears. The driving gear meshes with one of the transmission gears.

[0015] When the drive motor is working, it drives the drive gear to rotate, which in turn drives one of the transmission gears to rotate. The transmission gears then drive the driven gears to rotate one by one, thereby driving multiple rollers to rotate synchronously and in the same direction.

[0016] In the above-mentioned glass fiber cotton winding device, a push port is provided on the support plate opposite to the discharge port. The push component includes a push plate provided in the push port and a linear drive component provided on the side of the push plate away from the discharge port. A bracket is also provided on the support plate opposite to the discharge port, and the linear drive component is provided on the bracket.

[0017] The linear drive component is a cylinder / hydraulic cylinder / linear motor, used to drive the push plate to move linearly along the length of the cotton roll, thereby pushing the cotton roll.

[0018] In the above-mentioned glass fiber cotton winding device, the support plate is provided with through holes corresponding to a plurality of winding rollers, and bearings are provided in the through holes, with the ends of the winding rollers passing through the corresponding bearings.

[0019] In the aforementioned glass fiber cotton winding device, a connecting rod is provided between the two support plates. The connecting rod connects the two support plates into one unit, enhancing the overall structural strength.

[0020] The method for winding up fiberglass wool includes the following steps:

[0021] S1. Turn on the drive motor. Through the sequential meshing of the drive gear, transmission gear and driven gear, all the rollers rotate synchronously and in the same direction at a uniform speed.

[0022] S2. Start the reduction motor to drive all the conveying rollers to rotate synchronously in the same direction, and convey the long strip of glass fiber cotton horizontally forward at a uniform speed along the conveying rollers, so that the front end of the glass fiber cotton is smoothly delivered to the feed port position.

[0023] S3. The front end of the glass fiber cotton gradually detaches from the support surface of the conveyor roller and falls naturally downward under its own gravity until it is stably attached to the roller surface of the corresponding roll below the feed inlet.

[0024] S4. The continuously rotating rollers rely on surface friction to drive the glass fiber cotton to be continuously conveyed in a circumferential direction along the inner wall of the roll cavity, and the cotton material moves smoothly along the trajectory of the roll cavity.

[0025] S5. The front end of the glass fiber cotton abuts against the surface of the guide roller. Under the limiting and guiding action of the guide roller, the front end of the glass fiber cotton is forced to bend inward and precisely extends and overlaps to the inner side of the glass fiber cotton that subsequently enters the roll cavity below.

[0026] S6. After the front end of the glass fiber cotton is folded and overlapped, it continues to move along the inner track as the roller rotates. Under the coordinated circular conveying action of several rollers, the glass fiber cotton is rolled up layer by layer in the roll cavity to gradually form a cylindrical cotton roll.

[0027] S7. When the cotton roll reaches the preset forming diameter, the pneumatic cutter assembly at the feed inlet automatically moves to neatly cut the entire strip of glass fiber cotton; then the drive motor and conveyor roller power are turned off, and the roll and conveyor roller stop running.

[0028] S8. The operator pre-places the packaging bag on the outside of the multiple guide rods outside the discharge port, starts the linear drive of the push component, drives the push plate to move forward smoothly, pushes the well-formed cotton roll in the roll cavity out through the discharge port, slides into the packaging bag along the guide channel formed by the guide rods, completes the automatic bagging and sealing, and only needs to be sealed before storage.

[0029] Compared with the prior art, the present invention has the following advantages:

[0030] This invention, by setting a guide at the inlet of the glass fiber cotton winding device, can guide the front end of the glass fiber cotton downward to the inside of the glass fiber cotton at the inlet. This effectively solves the problem in existing winding devices where the front end of the cotton roll easily comes into contact with glass fiber cotton that has not entered the inner cavity of the roll, resulting in winding failure and requiring manual intervention. This improves the stability and automation of the winding process. Attached Figure Description

Detailed Implementation

[0036] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0037] like Figure 2 and Figure 3The glass fiber cotton winding device shown includes two opposing support plates 1, a plurality of (22 in this embodiment) winding rollers 2 rotatably disposed between the two support plates 1, and a power component for driving the plurality of winding rollers 2 to rotate synchronously and in the same direction. A connecting rod 16 is provided between the two support plates 1, which connects the two support plates 1 into one unit to enhance the overall structural strength.

[0038] like Figure 2 and Figure 3 As shown, several rollers 2 are parallel to each other and arranged in a ring, as follows: Figure 4 As shown, several winding rollers 2 form a winding cavity, and one side of the winding cavity has a feed inlet 3, as shown. Figure 2 As shown, one of the support plates 1 is provided with a discharge port 4 that communicates with the winding cavity. The diameter of the discharge port 4 is larger than the inner diameter of the winding cavity, such as... Figure 3 As shown, another support plate 1 is provided with a pusher assembly for pushing the cotton roll located in the roll chamber out of the outlet 4.

[0039] In this embodiment, in order to facilitate the rotation of the roller 2, the support plate 1 is provided with through holes corresponding to the multiple rollers 2, and bearings are provided in the through holes. The ends of the rollers 2 pass through the bearings corresponding to them.

[0040] like Figure 3 As shown, the power assembly includes a driven gear 9, a driving gear 10, and a drive motor 11 coaxially fixed to the roller 2. The driving gear 10 is driven by the drive motor 11. A transmission gear 12 meshes with each of two adjacent driven gears 9. The driving gear 10 meshes with one of the transmission gears 12. When the drive motor 11 is working, it drives the driving gear 10 to rotate, which in turn drives one of the transmission gears 12 to rotate. The transmission gears 12 then drive each of the driven gears 9 to rotate, thereby causing multiple rollers 2 to rotate synchronously and in the same direction.

[0041] like Figure 3 and Figure 4 As shown, a push port is provided on the support plate 1 opposite to the discharge port 4. The push assembly includes a push plate 13 disposed in the push port and a linear drive component 14 disposed on the side of the push plate 13 away from the discharge port 4. A bracket 15 is also provided on the support plate 1 opposite to the discharge port 4, and the linear drive component 14 is disposed on the bracket 15. The linear drive component 14 is a cylinder / hydraulic cylinder / linear motor, used to drive the push plate 13 to move linearly along the length of the cotton roll, thereby pushing the cotton roll.

[0042] like Figure 2As shown, the support plate 1 with the discharge port 4 has multiple (four in this embodiment) horizontally extending guide rods 8 on its outer side. The guide rods 8 are evenly distributed around the discharge port 4, and the outer diameter of the guide channel formed by the guide rods 8 is not less than the diameter of the discharge port 4. The length of the guide rods 8 should be greater than the length of the cotton roll. When the cotton roll is pushed out of the discharge port 4, it will enter the guide channel formed by the guide rods 8. At this time, the nylon bag / plastic bag can be put over the guide rods 8, and the cotton roll can be directly put into the nylon bag / plastic bag.

[0043] like Figure 2 As shown, horizontally extending guide rails 6 are fixed on both support plates 1. The two guide rails 6 are arranged opposite each other, and several conveying rollers 7 are installed between the two guide rails 6. The several conveying rollers 7 are located at the same height, and the height of the rolling roller 2 located below the feed inlet 3 is not higher than the height of the conveying rollers 7. The several conveying rollers 7 are connected by chain and sprocket transmission, so that the several conveying rollers 7 can rotate synchronously and in the same direction, and are driven by the same geared motor, thereby achieving the purpose of conveying glass fiber cotton a.

[0044] like Figure 4 As shown, a guide is provided at the feed inlet 3. The guide guides the front end of the glass fiber cotton a downward to the inner side of the glass fiber cotton a located at the feed inlet 3. In this embodiment, the guide includes a guide roller 5 located between the two support plates 1. The guide roller 5 is parallel to the winding roller 2. The guide roller 5 is located above the feed inlet 3 and partially extends into the winding cavity. The horizontal distance from the winding roller 2 located below the feed inlet 3 to the center line of the winding cavity is less than the horizontal distance from the guide roller 5 to the center line of the winding cavity. The glass fiber cotton a, like a quilt, is long and strip-shaped. After its front end enters the winding cavity through the feed inlet 3, it moves downward under the action of gravity until it comes into contact with the winding roller 2 located below it. The rotating winding roller 2 conveys the glass fiber cotton a forward along the inner wall of the winding cavity until the front end of the glass fiber cotton a is guided by the guide, so that the front end of the glass fiber cotton a extends to the inner side of the glass fiber cotton a, avoiding winding failure. That is, it is equivalent to folding the front end of the downward-extending glass fiber cotton a inward at a certain angle by the guide roller 5.

[0045] In addition to using guide roller 5, other embodiments may also use structures such as guide plate or guide rod 8, as long as they can guide the front end of glass fiber cotton a to the inside of glass fiber cotton a.

[0046] In this embodiment, the guide roller 5 is rotated.

[0047] The glass fiber wool winding method, using the above-mentioned winding device, includes the following steps:

[0048] S1. Start the drive motor 11. Through the step-by-step meshing of the drive gear 10, transmission gear 12 and driven gear 9, all the rollers 2 are driven to rotate synchronously and in the same direction at a uniform speed.

[0049] S2. Start the reduction motor to drive all the conveying rollers 7 to rotate synchronously in the same direction, and convey the long strip of glass fiber cotton a horizontally forward at a uniform speed along the conveying rollers 7, so that the front end of the glass fiber cotton a is smoothly delivered to the feed inlet 3.

[0050] S3. The front end of the glass fiber cotton a gradually detaches from the support surface of the conveying roller 7 and falls naturally downward under its own gravity until it is stably attached to the roller surface of the corresponding winding roller 2 below the feed inlet 3.

[0051] S4. The continuously rotating roller 2 drives the glass fiber cotton a by surface friction to continuously convey it in a circumferential direction along the inner wall of the roll cavity. The cotton material moves smoothly along the trajectory of the roll cavity.

[0052] S5. The front end of the glass fiber cotton a abuts against the roller surface of the guide roller 5. Under the limiting and guiding action of the guide roller 5, the front end of the glass fiber cotton a is forced to bend inward and precisely extends and overlaps to the inner side of the glass fiber cotton a that subsequently enters the roll cavity below.

[0053] S6. After the front end of the glass fiber cotton a is folded and overlapped, it continues to move along the inner track as the roller 2 rotates. Under the coordinated circular conveying action of several rollers 2, the glass fiber cotton a is rolled up layer by layer in the roll cavity, gradually forming a cylindrical cotton roll.

[0054] S7. When the cotton roll reaches the preset forming diameter, the pneumatic cutter assembly at the feed inlet 3 automatically moves to neatly cut the entire glass fiber cotton a; then the power of the drive motor 11 and the conveyor roller 7 is turned off, and the rolling roller 2 and the conveyor roller 7 stop running.

[0055] S8. The operator pre-places the packaging bag on the outside of the multiple guide rods 8 outside the discharge port 4, starts the linear drive component 14 of the push assembly, drives the push plate 13 to move forward smoothly, pushes the well-formed cotton roll in the roll cavity out through the discharge port 4, slides into the packaging bag along the guide channel formed by the guide rods 8, and completes the automatic bagging and sealing. Afterwards, only sealing is required before storage.

[0056] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
