Description

Technical Field

[0001] This invention relates to the field of thermal insulation cotton cutting technology, and more specifically, to a cutting mechanism and cutting method for a thermal insulation cotton conveyor. Background Technology

[0002] Currently, thermal insulation cotton made from ultra-light aluminum silicate fiber needs to be cut after being compacted and dried during the manufacturing process to facilitate segmented winding and boxing. During the cutting process, because the thermal insulation cotton is relatively soft, it is easy to deform when the cutter cuts it, making it difficult to cut. Therefore, the cutter needs to be sharper and the cutting force needs to be greater, which increases the frequency of equipment maintenance and affects the life of the cutter, which is a shortcoming. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cutting mechanism and cutting method for a thermal insulation cotton conveyor, thereby improving service life and reducing maintenance frequency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a cutting mechanism for a thermal insulation cotton conveyor, comprising a first conveyor frame, a second conveyor frame, a rotating drum, and rollers. The first and second conveyor frames are spaced apart and both are used for conveying. The upper end surfaces of the first and second conveyor frames are both conveying surfaces. The rotating drum is located between the first and second conveyor frames. Two rotating drums are spaced apart along the conveying direction of the first and second conveyor frames. The rollers are located above the rotating drums and are arranged in a one-to-one correspondence. The rollers can move up and down to approach or move away from the rotating drum. The invention also includes an upper die and a lower die, which are arranged vertically opposite each other. The upper die can move up and down to approach or move away from the lower die. The upper die is located between the two rollers, and the lower die is located between the two rollers. When the rollers move downward to abut against the rotating drum, the upper die moves downward and forms a shearing action with the lower die.

[0005] The invention is further configured such that the rotating drum can rotate along its own axis. When the roller is in contact with the rotating drum, the top of the rotating drum on the side closer to the first conveyor frame rotates toward the first conveyor frame, and the top of the rotating drum on the side closer to the second conveyor frame rotates toward the second conveyor frame. When the roller is in contact with the rotating drum, the rotation of the rotating drum drives the roller to rotate.

[0006] The invention is further configured such that the rotating drum can move up and down, and when the rotating drum is at its upper limit position, the upper end of the rotating drum is higher than the upper end of the first conveyor frame.

[0007] The invention is further configured to include a rotating shaft that can rotate along its own axis, a rotating cylinder having a first groove having a wall, and protrusions on both sides of the rotating shaft having sidewalls. When the sidewalls are in contact with the wall, the rotating shaft rotates to drive the rotating cylinder to rotate.

[0008] The invention is further configured such that the rotating shaft is driven to rotate by a driving component, which is a rotary cylinder. The rotating shaft rotates at an angle of 0 degrees. When the rotating cylinder moves up and down, the side wall and the wall surface are both set in the horizontal direction, and the width direction of the first groove is set in the vertical direction, with the side wall located above the wall surface.

[0009] The invention is further configured such that bearing sleeves are installed on the outer walls of both axial ends of the rotating drum via bearings, the bearing sleeves are slidably connected to the support frame, and the bearing sleeves can move up and down along the inner wall of the support frame.

[0010] The present invention is further configured such that the support frame includes limiting blocks located on both sides, the bearing sleeve is located between the two limiting blocks, and the bearing sleeve moves up and down along the wall surface of the limiting blocks; a fixing block is installed at the bottom of the support frame, the fixing block has a countersunk hole, an insertion rod is installed at the bottom of the bearing sleeve, the insertion rod is inserted into the countersunk hole, and a spring is installed between the bottom surface of the countersunk hole and the bottom surface of the insertion rod.

[0011] The present invention is further configured to include a bearing housing, wherein the end of the rotating shaft away from the driving component is connected to the bearing housing via a bearing.

[0012] The invention is further configured to include a lifting seat, which is capable of moving up and down. The lifting seat is equipped with a shaft, and a roller is rotatably connected to the outer wall of the shaft. The upper die passes through the lifting seat.

[0013] The present invention also adopts the following technical solution: a cutting method for an insulation cotton conveyor, which uses the cutting mechanism of the insulation cotton conveyor to cut the insulation cotton, including the following steps:

[0014] ① The rotating drum is at its upper limit position, the wall is above the side wall and the two are in contact with each other, the roller moves downward and the roller and the rotating drum press the insulation cotton tightly;

[0015] ② The rotating drum rotates 180 degrees, and the two rotating drums on both sides rotate to stretch the insulation cotton;

[0016] ③ The rollers continue to move downwards, pushing the drum downwards, and the insulation cotton approaches and abuts the lower die;

[0017] ④ The upper die moves downward, and the upper die and the lower die form a shearing action to cut the insulation cotton.

[0018] In summary, the present invention has the following beneficial effects:

[0019] When the rollers are in contact with the rotating drum, the top of the rotating drum on the side closer to the first conveyor frame rotates toward the first conveyor frame, and the top of the rotating drum on the side closer to the second conveyor frame rotates toward the second conveyor frame. This causes the insulation cotton on both sides of the lower die to be tightened. At this time, when the upper die cuts the insulation cotton, the insulation cotton is not easy to yield or bend, which makes cutting easier. The cutting force of the upper die is reduced, which improves the service life and reduces the maintenance frequency. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figures 1-7 As shown, this embodiment discloses a cutting mechanism for a thermal insulation cotton conveyor, including a first conveyor frame 1 and a second conveyor frame 11. Both the first conveyor frame 1 and the second conveyor frame 11 are used to convey thermal insulation cotton 4. The upper end surface of the first conveyor frame 1 and the upper end surface of the second conveyor frame 11 are both conveying surfaces. The upper end surface of the first conveyor frame 1 and the upper end surface of the second conveyor frame 11 are at the same height. The first conveyor frame 1 and the second conveyor frame 11 are arranged at intervals. The thermal insulation cotton 4 is conveyed from the first conveyor frame 1 to the second conveyor frame 11.

[0030] like Figure 1 , Figure 2 As shown, it also includes a rotating drum 7, which is located between the first conveyor frame 1 and the second conveyor frame 11. Two rotating drums 7 are spaced apart along the conveying direction of the first conveyor frame 1 and the second conveyor frame 11. The rotating drum 7 has a cylindrical structure, as shown... Figure 4 As shown, bearing sleeves 8 are installed on the outer walls of both axial ends of the rotating drum 7 via bearings. The rotating drum 7 passes through the bearing sleeves 8, and the bearing sleeves 8 are slidably connected to the support frame 6. The bearing sleeves 8 can move up and down along the inner wall of the support frame 6. Specifically, combined with Figure 4 , Figure 5 The support frame 6 includes limiting blocks 61 located on both sides, and the bearing sleeve 8 is located between the two limiting blocks 61. The bearing sleeve 8 moves up and down along the wall of the limiting blocks 61.

[0031] like Figure 4 As shown, a fixing block 62 is installed at the bottom of the support frame 6. The fixing block 62 has a countersunk hole 621. A plug rod 64 is installed at the bottom of the bearing sleeve 8. The plug rod 64 is inserted into the countersunk hole 621. A spring 63 is installed between the bottom surface of the countersunk hole 621 and the bottom surface of the plug rod 64. The upper and lower ends of the spring 63 abut against the bottom surface of the countersunk hole 621 and the bottom surface of the plug rod 64, respectively.

[0032] like Figure 3 , Figure 4 As shown, the rotating drum 7 can rotate along its own axis. Specifically, the rotating drum 7 has a first groove 71 with a wall surface 711. A rotating shaft 21 is inserted into the rotating drum 7. A driving component 2, which is a rotary cylinder, is connected to one end of the rotating shaft 21. The rotating shaft 21 can rotate along its own axis under the drive of the driving component 2. The rotation angle of the rotating shaft 21 is 180 degrees. A bearing seat 65 is mounted on the rotating shaft 21 through a bearing. The bearing seat 65 is mounted on the support frame 6. The rotating shaft 21 has protrusions 211 on both sides, each protrusion including a side wall 2111. When the side wall 2111 is in contact with the wall surface 711, the rotating shaft 21 rotates, driving the rotating drum 7 to rotate.

[0033] like Figure 1 , Figure 2 As shown, the assembly includes a lifting base 5 and an upper die 51. The lifting base 5 is driven to rise and fall by a hydraulic cylinder, and a separate hydraulic cylinder is installed on the lifting base 5 to drive the upper die 51 to move up and down. The lifting base 5 is equipped with a shaft 521, and the shaft 521 is rotatably connected to a roller 52. The roller 52 is located above the rotating drum 7, and the roller 52 is arranged in a one-to-one correspondence with the rotating drum 7. Under the drive of the lifting base 5, the roller 52 can move up and down to approach or move away from the rotating drum 7.

[0034] It also includes a lower die 3 and an upper die 51. The lower die 3 and the upper die 51 are arranged vertically opposite each other. The upper die 51 moves up and down to move closer to or away from the lower die 3. The upper die 51 is located between two rollers 52, and the lower die 3 is located between two rollers 52. When the rollers 52 move downward and abut against the rotating drum 7, the upper die 51 moves downward and forms a shearing action with the lower die 3 to cut the insulation cotton 4.

[0035] When the roller 52 is in contact with the rotating drum 7, the top of the rotating drum 7 on the side closer to the first conveyor frame 1 rotates toward the first conveyor frame 1, and the top of the rotating drum 7 on the side closer to the second conveyor frame 11 rotates toward the second conveyor frame 11, so that the insulation cotton 4 on the left and right sides of the lower die 3 is tightened. At this time, when the upper die 51 cuts the insulation cotton 4, the insulation cotton 4 is not easy to yield and bend, thus facilitating cutting. The cutting force of the upper die 51 is reduced, which improves the service life and reduces the maintenance frequency.

[0036] Roller 52 is a driven wheel. When roller 52 is in contact with rotating drum 7, rotating drum 7 drives roller 52 to rotate. To be precise, when roller 52 and rotating drum 7 are pressing down on the insulation cotton 4, rotating drum 7 rotates and drags the insulation cotton 4 to move and pull it apart. Roller 52 rotates and adjusts accordingly as the insulation cotton 4 moves.

[0037] like Figure 1 As shown, due to the setting of spring 63, insert rod 64, etc., the rotating drum 7 can move up and down. When the rotating drum 7 is at the upper limit position, the upper end of the rotating drum 7 is higher than the upper end of the first conveyor frame 1, which facilitates the transfer of the insulation cotton 4 from the first conveyor frame 1 to the second conveyor frame 11. When the front conveying end of the insulation cotton 4 is just sent out from the right side of the first conveyor frame 1, the conveying height can be increased by the rotation of the rotating drum 7, which facilitates the connection of the insulation cotton 4 between the first conveyor frame 1 and the second conveyor frame 11.

[0038] like Figure 2 , Figure 3 As shown, the first groove 71 is connected to the second groove 72. In the initial state, the first groove 71 and the second groove 72 are vertically connected to the rotating cylinder 7, the second groove 72 is connected to the top of the rotating cylinder 7, and the first groove 71 is connected to the bottom of the rotating cylinder 7. The side wall 2111 and the wall surface 711 are both set in the horizontal direction, and the wall surface 711 is located above the side wall 2111. At this time, the roller 52 moves downward, and the roller 52 and the rotating cylinder 7 slightly press the insulation cotton 4. The rotating shaft 21 rotates 180 degrees, driving the rotating cylinder 7 to rotate. The left rotating cylinder 7 rotates counterclockwise, and the right rotating cylinder 7 rotates clockwise. The rotation of the two rotating cylinders 7 stretches the insulation cotton 4.

[0039] When the rotating drum 7 rotates 180 degrees from its initial state, with the side wall 2111 above the wall surface 711, the rotating drum 7 can move downwards under the pressure of the roller 52, so that the insulation cotton 4 is closer to the lower die 3, thus facilitating cutting by the upper die 51. Because the lower die 3 is positioned lower, it avoids interfering with the transmission of the insulation cotton 4.

[0040] The outer wall of the rotating drum 7 is fitted with an outer pad 2 73, and the outer wall of the roller 52 is fitted with an outer pad 1 522. Both the outer pad 2 73 and the outer pad 1 522 are made of silicone.

[0041] A cutting method for an insulation cotton conveyor, using the cutting mechanism of the aforementioned insulation cotton conveyor, includes the following steps:

[0042] ① The rotating drum 7 is located at the upper limit position, the wall surface 711 is located above the side wall 2111 and the two are in contact with each other, the roller 52 moves downward, and the roller 52 and the rotating drum 7 slightly press the insulation cotton 4.

[0043] ② The rotating shaft 21 rotates 180 degrees and drives the rotating drum 7 to rotate synchronously. The left rotating drum 7 rotates counterclockwise and the right rotating drum 7 rotates clockwise. The rotating drums 7 on both sides rotate to stretch the insulation cotton 4. The wall surface 711 is located below the side wall 2111.

[0044] ③ The roller 52 continues to move downward and pushes the rotating drum 7 downward. The wall 711 separates from the side wall 2111, and the insulation cotton 4 approaches and abuts the lower die 3.

[0045] ④ The upper die 51 moves downward, and the upper die 51 and the lower die 3 form a shearing action to cut the insulation cotton 4.

[0046] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
