Description

Technical Field

[0001] This invention relates to the field of sound-absorbing cotton production technology, and in particular to a heat-sealing device and method for double-layer sound-absorbing cotton. Background Technology

[0002] Sound-absorbing cotton is a type of man-made inorganic fiber. It is made from natural minerals such as quartz sand, limestone, and dolomite as the main raw materials, and is melted into glass with some chemical raw materials such as soda ash and borax. It has the advantages of high sound absorption rate and good sound insulation performance.

[0003] During production, sound-absorbing cotton requires hot-pressing and die-cutting. The complete sound-absorbing cotton is conveyed to the hot-pressing processing area on the hot-pressing equipment. The machine presses down to complete the hot-pressing process. The die-cut sound-absorbing cotton is then conveyed out along with other materials. The sealed sound-absorbing cotton is then manually removed, completing the hot-pressing step. Currently, there is a type of double-layer sound-absorbing cotton. When fed onto the hot-pressing equipment, there are two layers of material. After moving to the hot-pressing processing area, the machine presses down to hot-press the two layers together, thus completing the hot-pressing process for the double-layer sound-absorbing cotton.

[0004] The invention disclosed in CN115401918A proposes a high-temperature edge-sealing device for sound-absorbing cotton. This device transports the sound-absorbing cotton via an infeed conveyor belt and an outfeed conveyor belt. A drive gear drives a cutting component and a heat-sealing component to move alternately up and down. First, the heat-sealing component heat-seals the sound-absorbing cotton, then the cutting component cuts it into the required shape. A spiral heating core quickly heats the heating mold. However, when heat-sealing double-layer sound-absorbing cotton, the conveyor belt can only transport the bottom layer. The upper layer is prone to misalignment during transport, resulting in misalignment of the upper and lower layers. This leads to excessive debris after heat-sealing and die-cutting, affecting the overall production efficiency of the double-layer sound-absorbing cotton heat-sealing process. Therefore, this solution proposes a double-layer sound-absorbing cotton heat-sealing equipment and method to address these problems. Summary of the Invention

[0005] In view of this, the present invention proposes a double-layer sound-absorbing cotton heat-sealing device. A partition separates the upper and lower sound-absorbing cottons. The two sound-absorbing cottons are transported by feeding mechanisms located inside the upper and lower feeding chambers respectively. By adjusting the transmission speed of the feeding mechanisms to be consistent, the two sound-absorbing cottons can always be aligned vertically during transmission, preventing misalignment of the two sound-absorbing cottons during heat sealing and thus avoiding an increase in impurities, which is convenient to use.

[0006] The technical solution of this invention is implemented as follows: This invention provides a double-layer sound-absorbing cotton heat-sealing device, including a base frame, pads, mounting side frames, partitions, a feeding mechanism, and a hydraulic heat-sealing mechanism, wherein,

[0020] Based on the above technical solutions, a preferred embodiment also includes an installation cover, wherein...

[0021] There are two mounting covers, which are respectively set on the two mounting side frames. The transmission gear is located inside the mounting cover, and the first motor is set on the mounting cover.

[0022] Based on the above technical solutions, a preferred embodiment also includes a cutting plate, wherein...

[0023] The pad block is provided with a material discharge through hole;

[0024] A feeding plate is disposed inside the feeding through hole, and both ends of the feeding plate are inclined from the side closer to the sound-absorbing cotton to the side farther away from the sound-absorbing cotton.

[0025] Based on the above technical solutions, preferably, it also includes a rotary wheel and a pressure plate, wherein,

[0026] A rotating wheel is rotatably positioned on the side of the sound-absorbing cotton away from the pad block;

[0027] Multiple pressure plates are arranged at equal intervals around the circumference of the rotary wheel to squeeze the sound-absorbing cotton toward the side closest to the discharge through hole.

[0028] Based on the above technical solutions, the preferred embodiment also includes an assembly, a shaft, and a second motor, wherein...

[0029] The components are mounted on the base frame;

[0030] A shaft is rotatably mounted on the assembly, and the rotating wheel is mounted on the shaft;

[0032] Based on the above technical solutions, preferably, the system also includes a sliding guide rail, a sliding component, a storage bin, and a snap-fit ​​component, wherein...

[0033] A sliding guide rail is provided on the side of the pad away from the sound-absorbing cotton;

[0034] A slider is slidably mounted on the sliding guide rail;

[0035] A storage bin is mounted on the sliding member and slides towards or away from the discharge through hole. A receiving port is provided on the side corresponding to the discharge through hole.

[0036] A snap-fit ​​component is used to position the slider relative to the sliding guide rail.

[0037] Based on the above technical solutions, preferably, the locking component includes a locking block and a spring, wherein,

[0038] The sliding guide rail has a mounting groove, and the locking block is slidably disposed inside the mounting groove. One end of the locking block protruding from the mounting groove is arc-shaped, and the sliding member has a positioning groove for the end of the locking block to be inserted into.

[0039] A spring, disposed between the sliding guide rail and the locking block, is used to reset the sliding position of the locking block relative to the mounting groove.

[0040] The double-layer sound-absorbing cotton heat-sealing method, including the double-layer sound-absorbing cotton heat-sealing equipment as described above, further includes the following steps:

[0041] S1. Place two sound-absorbing cotton pieces overlapping each other on top of the pad block, and insert the opposite sides of the two sound-absorbing cotton pieces into the upper and lower feeding chambers respectively. At this time, the feeding belt is in contact with the sound-absorbing cotton pieces.

[0042] S2. Start the first motor. At this time, the feeding belts in the upper and lower feeding chambers independently transmit the two sound-absorbing cottons. The transmission speed of the upper and lower feeding belts is the same, so that the two sound-absorbing cottons can be transmitted synchronously on the pad.

[0043] S3. When the two sound-absorbing cottons move to the hydraulic heat sealing mechanism, the hydraulic heat sealing mechanism completes the heat sealing process of the sound-absorbing cottons. The heat-sealed sound-absorbing cottons are then transported synchronously on the pad along with the surrounding debris.

[0044] S4. When the sound-absorbing cotton moves to the rotating wheel, the second motor is started and drives the rotating wheel to rotate. The rotating wheel drives the pressure plate to rotate. The rotating pressure plate squeezes the heat-sealed sound-absorbing cotton towards the direction of the discharge hole, so that the heat-sealed sound-absorbing cotton is separated from the debris and falls into the interior of the discharge hole. Under the guidance of the discharge plate, it falls into and is stored in the interior of the storage box.

[0045] S5. When it is necessary to remove the sound-absorbing cotton after heat sealing, pull the storage box outward to make the sliding part slide away from the sliding guide rail, thereby removing the storage box from the sliding guide rail, so as to take out the sound-absorbing cotton stored inside the storage box.

[0046] The double-layer sound-absorbing cotton heat-sealing device and method of the present invention have the following advantages over the prior art:

[0047] (1) By setting up a side frame, during use, two sound-absorbing cottons overlap and are placed on top of the pad. At this time, the opposite sides of the sound-absorbing cottons are inserted into the upper and lower feeding chambers respectively. The partition separates the upper and lower sound-absorbing cottons. The two sound-absorbing cottons are transported by the feeding mechanism located inside the upper and lower feeding chambers respectively. By adjusting the transmission speed of the feeding mechanism to be consistent, the two sound-absorbing cottons can move along the length of the pad without interfering with each other for heat sealing. The synchronous transmission of the two sound-absorbing cottons can keep them aligned vertically, preventing misalignment during heat sealing and thus increasing the amount of impurities, which is convenient for use.

[0048] (2) By setting a feeding through hole, after the sound-absorbing cotton has completed the heat sealing process, the heat-sealed sound-absorbing cotton can continue to be transported on the pad along with the surrounding debris. When the sound-absorbing cotton moves to the feeding through hole, it can be squeezed downwards to remove the surrounding debris and squeeze into the inside of the feeding through hole. At this time, one end of the sound-absorbing cotton moves to the lower part of the feeding plate. Since the feeding plate is set in an inclined position inside the feeding through hole, the feeding mechanism continues to transport the sound-absorbing cotton. The heat-sealed sound-absorbing cotton moves towards the feeding plate and gradually moves downwards under the restriction of the feeding plate and gets rid of the surrounding debris. The detached sound-absorbing cotton falls out from below, which is convenient for users to collect and use. Attached Figure Description

[0060] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0061] like Figures 1-10 As shown, the double-layer sound-absorbing cotton heat-sealing device of the present invention includes a base frame 11, a pad 12, mounting side frames 3, a partition 4, a feeding mechanism 5, and a hydraulic heat-sealing mechanism 6. The pad 12 is mounted on the base frame 11 and supports two sound-absorbing cottons 2 in the vertical direction. In specific implementation, the sound-absorbing cottons 2 are placed on top of the pad 12 and moved along the length of the pad 12 for heat-sealing. Two mounting side frames 3 are mounted on the base frame 11 and located on opposite sides of the sound-absorbing cottons 2. The mounting side frames 3 have assembly slots 31 for inserting the sides of the sound-absorbing cottons 2. The partition 4 is located inside the assembly slots 31, dividing the assembly slots 31 into an upper feeding chamber 311 and a lower feeding chamber. 312, two sound-absorbing cottons 2 are located inside the upper feeding chamber 311 and the lower feeding chamber 312 respectively. Specifically, when the sound-absorbing cotton 2 is being transported, the width of the sound-absorbing cotton 2 is slightly larger than the width of the pad 12 so that its side can be inserted into the inner side of the assembly groove 31. During this time, the two sound-absorbing cottons 2 are located inside the upper feeding chamber 311 and the lower feeding chamber 312 respectively and are separated by the partition 4. By independently transporting the two sound-absorbing cottons 2, the two sound-absorbing cottons 2 can move synchronously on the pad 12. There are multiple feeding mechanisms 5, which are respectively set inside each upper feeding chamber 311 and the lower feeding chamber 312 for transporting the sound-absorbing cotton 2. The hydraulic heat sealing mechanism 6 is set on the base frame 11 for heat sealing the edges of the sound-absorbing cotton 2.

[0062] In practice, two sound-absorbing cottons 2 are placed on top of the pad 12, overlapping each other. The opposite sides of the sound-absorbing cottons 2 are inserted into the upper feeding chamber 311 and the lower feeding chamber 312, respectively. A partition 4 separates the upper and lower sound-absorbing cottons 2. The two sound-absorbing cottons 2 are transported by feeding mechanisms 5 located inside the upper and lower feeding chambers 311 and 312, respectively. By adjusting the transmission speed of the feeding mechanisms 5 to be consistent, the two sound-absorbing cottons 2 can move along the length of the pad 12 without interfering with each other, for heat sealing. Synchronous transport of the two sound-absorbing cottons 2 ensures that they are always aligned vertically, preventing misalignment during heat sealing and thus reducing material buildup, making it convenient to use.

[0063] In a preferred embodiment, the feeding mechanism 5 includes a feeding roller 51, a feeding belt 52, and a first motor 53. The feeding roller 51 is multiple and is rotatably disposed inside the upper feeding chamber 311 or the lower feeding chamber 312. The feeding belt 52 is connected to each feeding roller 51 and squeezes the sound-absorbing cotton 2 toward the side close to the partition 4. The first motor 53 is used to drive the feeding roller 51 to rotate.

[0064] In practice, when both sound-absorbing cotton 2 are inserted into the assembly slot 31, the partition 4 and the feeding belt 52 press the sound-absorbing cotton 2 from opposite sides. The first motor 53 starts and drives the feeding roller 51 to rotate. The feeding roller 51 drives the feeding belt 52 to rotate, and the rotating feeding belt 52 completes the feeding process of the sound-absorbing cotton 2.

[0065] In a preferred embodiment, the system further includes multiple connecting shafts 54 and multiple transmission gears 55. The multiple connecting shafts 54 pass through the mounting side frame 3 and extend into the interior of the upper feeding chamber 311 or the lower feeding chamber 312, and are fixedly connected to the feeding roller 51. The multiple transmission gears 55 are respectively disposed on each connecting shaft 54, and two transmission gears 55 disposed on one mounting side frame 3 mesh with each other. There are two first motors 53, which are respectively disposed on one side of the two mounting side frames 3, and are used to drive the transmission gears 55 to rotate.

[0066] In specific implementation, an upper feeding chamber 311 and a lower feeding chamber 312 on a mounting side frame 3 are respectively connected to a connecting shaft 54. The connecting shaft 54 ​​passes through the mounting side frame 3 and extends to the outside of the mounting side frame 3. Each connecting shaft 54 ​​is provided with a transmission gear 55. The transmission gears 55 mesh with each other. When the first motor 53 drives one transmission gear 55 to rotate, the other transmission gear 55 meshing with it rotates in the opposite direction, thereby completing the feeding process of the two sound-absorbing cotton 2 through the feeding belt 52.

[0067] In a preferred embodiment, the device also includes a mounting cover 56, wherein there are two mounting covers 56, which are respectively mounted on two mounting side frames 3, the transmission gear 55 is located inside the mounting cover 56, and the first motor 53 is mounted on the mounting cover 56.

[0068] With this design, the mounting cover 56 is placed on the mounting side frame 3 to shield and protect the transmission gear 55 during use, thereby ensuring the operational stability of the transmission gear 55.

[0069] In a preferred embodiment, a feeding plate 71 is also included, wherein a feeding through hole 121 is provided on the pad 12; the feeding plate 71 is disposed inside the feeding through hole 121, and both ends of the feeding plate 71 are inclined from the side closer to the sound-absorbing cotton 2 to the side away from the sound-absorbing cotton 2.

[0070] In practice, after the sound-absorbing cotton 2 has completed the heat-sealing process, the heat-sealed sound-absorbing cotton 2 can continue to be transported on the pad block 12 along with the surrounding debris. When the sound-absorbing cotton 2 moves to the discharge through hole 121, it can be squeezed downwards to remove the surrounding debris and squeeze into the discharge through hole 121. At this time, one end of the sound-absorbing cotton 2 moves to the lower part of the discharge plate 71. Since the discharge plate 71 is set in an inclined position inside the discharge through hole 121, the feeding mechanism 5 continues to transport the sound-absorbing cotton 2. The heat-sealed sound-absorbing cotton 2 moves towards the discharge plate 71 and gradually moves downwards under the restriction of the discharge plate 71 and gets rid of the surrounding debris. The detached sound-absorbing cotton 2 falls out from below, which is convenient for users to collect and use.

[0071] In a preferred embodiment, the device also includes a rotating wheel 72 and a pressure plate 73. The rotating wheel 72 is rotatably disposed on the side of the sound-absorbing cotton 2 away from the pad 12. The pressure plate 73 is a plurality of plates, which are equidistantly disposed on the periphery of the rotating wheel 72 and are used to squeeze the sound-absorbing cotton 2 toward the side close to the discharge through hole 121.

[0072] In practice, when the sound-absorbing cotton 2 moves to the rotating wheel 72, the rotating wheel 72 is adjusted to rotate and drive the pressure plate 73 to rotate. The rotating pressure plate 73 squeezes the sound-absorbing cotton 2 towards the side close to the discharge through hole 121, squeezing the heat-sealed sound-absorbing cotton 2 out from the debris connected to it and into the interior of the discharge through hole 121. This quickly squeezes the heat-sealed sound-absorbing cotton 2 into the interior of the discharge through hole 121, making it convenient to use.

[0073] In a preferred embodiment, the assembly 74, the shaft 75, and the second motor 76 are also included. The assembly 74 is mounted on the base frame 11. The shaft 75 is rotatably mounted on the assembly 74, and the wheel 72 is mounted on the shaft 75. The second motor 76 is used to drive the shaft 75 to rotate.

[0074] With this design, when the rotation of the rotating wheel 72 needs to be adjusted, the second motor 76 starts, the second motor 76 drives the shaft 75 to rotate, and the shaft 75 drives the rotating wheel 72 to rotate, thereby completing the automatic adjustment of the rotation of the rotating wheel 72 and automatic feeding. The feeding process does not require manual removal of the heat-sealed sound-absorbing cotton 2, which is convenient to use.

[0075] In a preferred embodiment, the device further includes a sliding guide rail 81, a sliding member 82, a storage box 83, and a snap-fit ​​component 9. The sliding guide rail 81 is disposed on the side of the pad 12 away from the sound-absorbing cotton 2. The sliding member 82 is slidably disposed on the sliding guide rail 81. The storage box 83 is disposed on the sliding member 82 and slides towards or away from the discharge through hole 121. A receiving port 831 is provided on the corresponding side of the discharge through hole 121. The snap-fit ​​component 9 is used to position the sliding position of the sliding member 82 relative to the sliding guide rail 81.

[0076] With this design, the sound-absorbing cotton 2 falling from the discharge hole 121 can be collected and stored by the storage box 83. In specific implementation, the sliding member 82 can slide from the sliding guide rail 81 to disengage from the sliding guide rail 81. When it is necessary to remove the sound-absorbing cotton 2 stored inside the storage box 83, the sliding member 82 is adjusted to slide out of the sliding guide rail 81, thereby removing the storage box 83 and facilitating the recycling of the sound-absorbing cotton 2 stored in the storage box 83. At the same time, when the storage box 83 moves to the receiving position, the locking member 9 positions the sliding position of the sliding member 82 relative to the sliding guide rail 81, so that the storage box 83 can stably receive the falling sound-absorbing cotton 2, which is convenient for use.

[0077] Preferably, the storage box 83 is provided with a handle 84 for the convenience of the user to pull the storage box 83.

[0078] In a preferred embodiment, the locking component 9 includes a locking block 91 and a spring 92. The sliding guide rail 81 has a mounting groove 811. The locking block 91 is slidably disposed inside the mounting groove 811, with one end protruding from the mounting groove 811 being arc-shaped. The sliding component 82 has a positioning groove 821 for the end of the locking block 91 to be inserted into. The spring 92 is disposed between the sliding guide rail 81 and the locking block 91 and is used to reset the sliding position of the locking block 91 relative to the mounting groove 811.

[0079] In practice, when the sliding member 82 slides to the locking block 91, the end of the locking block 91 protruding from the mounting groove 811 is arc-shaped. Therefore, the sliding member 82 will press down on the locking block 91 and move the locking block 91 into the mounting groove 811. The spring 92 is in a contracted state. When the storage box 83 moves to the receiving position, the locking block 91 and the positioning groove 821 are aligned. Under the action of the spring 92, the locking block 91 is inserted into the positioning groove 821, thereby completing the locking and positioning process of the sliding position of the sliding member 82.

[0080] A method for heat-sealing double-layer sound-absorbing cotton, comprising the double-layer sound-absorbing cotton heat-sealing equipment as described above, and further comprising the following steps:

[0081] Step 1: Place two sound-absorbing cotton 2 overlapping each other on top of the pad 12, and insert the opposite sides of the two sound-absorbing cotton 2 into the upper feeding cavity 311 and the lower feeding cavity 312 respectively. At this time, the feeding belt 52 is in contact with the sound-absorbing cotton 2, and the feeding step of the sound-absorbing cotton 2 is completed.

[0082] Step 2: Start the first motor 53. At this time, the feeding belts 52 located in the upper feeding chamber 311 and the lower feeding chamber 312 independently transport the two sound-absorbing cotton 2. The transmission speed of the upper and lower feeding belts 52 is the same. Since the upper and lower feeding belts 52 are in contact with the sound-absorbing cotton 2, the rotating feeding belts 52 can transport the sound-absorbing cotton 2. By adjusting the rotation speed of the two feeding belts 52 to be the same, the two sound-absorbing cotton 2 can be transported synchronously on the pad block 12. During the transmission process, the upper and lower sound-absorbing cotton 2 can always maintain an upper and lower alignment relationship.

[0083] Step 3: When the two sound-absorbing cottons 2 move to the hydraulic heat sealing mechanism 6, the hydraulic heat sealing mechanism 6 completes the heat sealing treatment of the sound-absorbing cottons 2. The heat-sealed sound-absorbing cottons 2 are then synchronously transported on the pad block 12 along with the surrounding debris.

[0084] Step 4: When the sound-absorbing cotton 2 moves to the rotating wheel 72, the second motor 76 is started and drives the rotating wheel 72 to rotate. The rotating wheel 72 drives the pressure plate 73 to rotate. The rotating pressure plate 73 squeezes the heat-sealed sound-absorbing cotton 2 towards the discharge hole 121, so that the heat-sealed sound-absorbing cotton 2 is separated from the debris and falls into the discharge hole 121. Under the guidance of the discharge plate 71, it falls into and is stored in the storage box 83. During the discharge process, the second motor 76 always drives the rotating wheel 72 to rotate at a constant speed. Whenever the heat-sealed sound-absorbing cotton 2 moves to the rotating wheel 72, the rotating pressure plate 73 will squeeze the heat-sealed sound-absorbing cotton 2 into the discharge hole 121, thereby completing the automatic collection and processing of the sound-absorbing cotton 2.

[0085] Step 5: When it is necessary to remove the heat-sealed sound-absorbing cotton 2, pull the storage box 83 outward to slide the sliding member 82 away from the sliding guide rail 81, thereby removing the storage box 83 from the sliding guide rail 81 to facilitate the removal of the sound-absorbing cotton 2 stored inside the storage box 83.

[0086] The working principle of this invention is described below:

[0087] Two sound-absorbing cottons 2 are placed overlapping each other on top of the pad 12. At this time, the opposite sides of the two sound-absorbing cottons 2 are inserted into the upper feeding cavity 311 and the lower feeding cavity 312 respectively, and are in contact with the feeding belt 52. The first motor 53 drives the feeding belt 52 to rotate, so that the feeding belt 52 conveys the two sound-absorbing cottons 2 separately. The two sound-absorbing cottons 2 are conveyed independently under the restriction of the partition 4. Adjusting the conveying speed of the feeding belt 52 to be consistent can ensure that the two sound-absorbing cottons 2 are always conveyed on the equipment in a vertically aligned manner. When the sound-absorbing cottons 2 move to the hydraulic heat sealing mechanism 6, the hydraulic heat sealing mechanism 6 completes the heat sealing process of the sound-absorbing cottons 2. After heat sealing, the sound-absorbing cotton 2 moves to the rotating wheel 72. The second motor 76 drives the rotating wheel 72 to rotate, and the rotating wheel 72 drives the pressure plate 73 to rotate. The pressure plate 73 presses the heat-sealed sound-absorbing cotton 2 into the discharge through hole 121. Under the action of the discharge plate 71, it falls from below and into the storage box 83. The storage box 83 stores the heat-sealed sound-absorbing cotton 2. When it is necessary to take out the sound-absorbing cotton 2 stored in the storage box 83, the adjusting sliding member 82 slides to disengage from the sliding guide rail 81, so as to take out the storage box 83 and collect the sound-absorbing cotton 2 stored in the storage box 83.

[0088] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
