Description

Technical Field

[0001] The invention relates to a device, in particular to a non-sticking and non-stop cutting and winding device. Background Art

[0002] In many fields such as medical dressings and waterproof rolls, it is necessary to cut a whole piece of material such as non-woven fabrics and PVC films into multiple thinner material strips, and then perform subsequent operations such as applying medicine on the thinner material strips. The current cutting method is generally to cut the material strip into thin strips by using multiple parallel cutting knives arranged side by side, and then use a winding device to receive the material strip to form a material roll for standby use. The winding device includes a rotating shaft, on which a row of independent reels with a width basically the same as the thin strip are mounted, and each reel is used to receive and roll up a thin strip. In this way, after the material strip is cut, the adjacent thin strips are not separated, but are received by different reels on the winding device in the same direction. The vibration and shaking of the material strip during movement or the shaking of the winding device during rotation may cause the adjacent thin strips to squeeze and adhere to each other after rolling, making it difficult to separate the rolls of different thin strips. In addition, after the reel is fully rolled, it is necessary to stop the machine to change the roll and then work again. This intermittent operation mode affects work efficiency.

[0003] In view of this, it is a technical problem that the art hopes to solve to provide a winding device that can change rolls without stopping the machine and in which the rolls will not be squeezed and adhered to each other. Summary of the invention

[0004] The purpose of the present invention is to provide a non-sticking and non-stop cutting and winding device, which can be used to cut a whole piece of material strip and wind up the separated material strip, thereby avoiding mutual adhesion between material rolls and no need to stop when changing rolls, which can effectively improve work efficiency and quality.

[0005] In order to achieve the above object, the present invention adopts the following technical scheme:

[0006] A non-sticking and non-stop cutting and winding device comprises a frame, a cutting roller is mounted on the frame, and a plurality of cutting knives are arranged side by side on one side of the cutting roller; a first rotating frame and a second rotating frame are rotatably mounted on the frame, a first supporting roller and a second supporting roller are mounted on the first rotating frame, a first air knife is arranged between the first supporting roller and the second supporting roller, and a first material strip channel is left on one side of the first supporting frame; a third supporting roller and a fourth supporting roller are mounted on the second rotating frame, a second air knife is arranged between the third supporting roller and the fourth supporting roller, and a second material strip channel is left on one side of the third supporting roller; a first winding turret and a second winding turret are mounted on the frame, a first winding shaft, a second winding shaft, a first pushing roller and a second pushing roller are mounted on the first winding turret, and the The first winding shaft, the second winding shaft and the first pushing roller and the second pushing roller are arranged crosswise; the third winding shaft, the fourth winding shaft, the third pushing roller and the fourth pushing roller are installed on the second winding rotary frame, and the third winding shaft, the fourth winding shaft and the third pushing roller and the fourth pushing roller are arranged crosswise; after the first winding shaft is fully wound up with the material tape, the first winding rotary frame can rotate to place the second winding shaft in the winding position, and the first rotating frame can rotate and make the material tape contact with the reel on the second winding shaft through the second supporting roller; after the third winding shaft is fully wound up with the material tape, the second winding rotary frame can rotate to place the fourth winding shaft in the winding position, and the second rotating frame can rotate and make the material tape contact with the reel on the fourth winding shaft through the fourth supporting roller.

[0007] Preferably, the first rotating frame includes two first Z-shaped arms, one end of the first Z-shaped arm is installed on the frame via a first mounting shaft, the other end is provided with the first support roller and the second support roller, the first air knife is installed between the first support roller and the second support roller, the first material belt channel is formed between the second support roller and the first mounting shaft, and the first Z-shaped arm is connected to the first cylinder; the second rotating frame includes two second Z-shaped arms, one end of the second Z-shaped arm is installed on the frame via a second mounting shaft, the other end is provided with the third support roller and the fourth support roller, the second air knife is installed between the third support roller and the fourth support roller, the second material belt channel is formed between the fourth support roller and the second mounting shaft, and the second Z-shaped arm is connected to the second cylinder.

[0008] Preferably, the surfaces of the second support roller and the fourth support roller have buffering properties, and the first air knife and the second air knife both include a guide rod and a blade, and the blade is mounted on the guide rod and driven by gas.

[0009] Preferably, the cutters on one side of the cutting roller are arranged in parallel with equal intervals. After the entire material strip is cut into equal widths by the cutters, the odd-numbered material strips are received by the first winding rotary frame through the first group of guide rollers, and the even-numbered material strips are received by the second winding rotary frame through the second group of guide rollers.

[0010] Preferably, when the first rotating frame makes the material strip contact with the reel on the second winding shaft through the second support roller, the material strip contacts the first support roller at the same time, and the first air knife starts to act to cut off the material strip; when the second rotating frame makes the material strip contact with the reel on the fourth winding shaft through the fourth support roller, the material strip contacts the third support roller at the same time, and the second air knife starts to act to cut off the material strip.

[0011] Preferably, when the first air knife cuts off the material tape and contacts the first contact point at the same time, the PLC control system obtains the contact and starts timing, and drives the first winding turret to rotate and the first cylinder to move according to the preset time for fully filling the material tape, and drives the first air knife to complete the re-cutting of the material tape; when the second air knife cuts off the material tape and contacts the second contact point at the same time, the PLC control system obtains the contact and starts timing, and drives the second winding turret to rotate and the second cylinder to move according to the preset time for fully filling the material tape, and drives the second air knife to complete the re-cutting of the material tape.

[0013] After the device cuts the entire piece of material strip through parallel cutters, the odd-numbered material strips and even-numbered material strips move in different directions under the action of the guide rollers and are received by the winding turret, so that the originally adjacent thin strips are separated and will not stick to each other. When it is necessary to change the roll, the roll that has been filled with material strips can be turned to the position through the rotation of the winding turret, and the empty roll on the already replaced winding shaft is rotated to the original winding position. In this process, the material strip will be pushed up by the pushing roller, and then the rotating frame will rotate to make the material strip contact with the new roll, and the material strip will be cut off at the same time. At this time, the original full roll is still rotating, and the tail end of the cut material strip is collected. At the same time, the new roll is also rotating, and the winding starts. The rotating frame is reset and left for the next cycle. In this way, when the new roll is wound, the full roll can be removed and replaced, so as to achieve the purpose of changing rolls without stopping the machine, which can effectively improve work efficiency.

[0018] The present invention will be further described below in conjunction with the accompanying drawings:

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention is a non-sticking and non-stop cutting and winding device, which includes a frame 1, a cutting roller 2 is installed on the frame 1, and a plurality of cutters 3 are arranged side by side above the cutting roller 2. In a preferred embodiment, these cutters are arranged in parallel with equal widths, and when a whole piece of material such as non-woven fabric, PVC film, etc. passes through the cutting roller, it is cut into thin strips of material with equal widths by the cutters 3 above. These material strips are numbered from one side to the other side and are divided into odd-numbered material strips 101 and even-numbered material strips 102. The odd-numbered material strips 101 move upwards under the action of the guide roller 103, and the even-numbered material strips 102 move downwards under the action of the guide roller 104.

[0020] A rotatable first rotating frame 4 is mounted on the frame 1, which includes two parallel Z-shaped arms 401. One end of the Z-shaped arm 401 is mounted on the frame 1 via a first mounting shaft 402, and the other end is mounted with a first support roller 403 and a second support roller 404. The Z-shaped arm 401 is also connected to a first cylinder 409. The Z-shaped arm can rotate upward under the push of the first cylinder, and can be reset after rotation. A first air knife 405 is mounted between the first support roller 403 and the second support roller 404. A first material belt channel 406 is formed between the second support roller 404 and the first mounting shaft 402. The odd-numbered material belt 101 passes through the first material belt channel 406 and is guided to the first winding rotating frame 5 by the guide roller 105. In one embodiment of the present invention, the first air knife 405 includes a guide rod 407 and a blade 408 mounted on the guide rod. The blade 408 is driven by gas to move quickly on the guide rod 407 to cut the material belt, and then the blade is reset in the opposite direction.

[0021] The first winding turret 5 is mounted on the frame 1, and includes two four-corner support plates 501 parallel to each other. The first winding shaft 502 and the second winding shaft 503 are mounted on two opposite corners of the four-corner support plates 501, and the first push-up roller 504 and the second push-up roller 505 are mounted on the other two opposite corners. The centers of the two four-corner support plates 501 are mounted on the support plate rotating shaft 506, and the support plate rotating shaft 506 drives the winding turret 5 to rotate. The first winding shaft 502 and the second winding shaft 503 have separate power drives and can rotate independently.

[0022] When winding, the odd-numbered material strip 101 passes through the first material strip channel 406 via the guide roller 103 and then is wound onto the reel on the first winding shaft 502 via the guide roller 105. The first winding shaft 502 rotates to wind. When the preset time is reached and the winding is completed, the first winding support rotates counterclockwise to the rear relative position (i.e., the first winding shaft and the second winding shaft exchange positions, and the second winding shaft is at the winding position) under the control of the PLC control system. During the rotation, the first push roller 504 pushes up the odd-numbered material strip 101, and the first winding shaft 502 keeps rotating. Figure 1 In the state shown, the first cylinder 409 then pushes the first rotating frame 4 to rotate upwards, at which time the second support shaft 404 lifts the odd-numbered tape up and contacts the reel on the second reel 503. The reel of the second reel is coated with glue, which can stick the tape. Therefore, at the same time, the odd-numbered tape 101 contacts the second support shaft 404 and the first support shaft 403 at the same time, that is, a plane is formed between the first and second support shafts. At this time, the first air knife 405 is activated, so that the blade 408 moves from one end to the other end on the guide rod 407, cutting off the odd-numbered tape 101, and then the blade 408 is reset. In this way, the second reel 503 starts to rewind, and the first reel 502 rewinds the tail of the cut odd-numbered tape, and then the first reel stops rotating. At this time, the material roll can be removed and replaced with a new reel for the next rewinding. During specific control, the first air knife can be made to contact the first contact point at the same time after cutting off the odd-numbered material strips. The PLC control system obtains the contact and starts timing. According to the preset time for filling up the material strips, the first winding turntable is driven to rotate and the first cylinder is driven to move and drive the first air knife to complete the re-cutting of the material strips.

[0023] In the above structure, the surface of the second support shaft can be made of a material with cushioning properties such as rubber, so that it has cushioning properties when in contact with the reel on the second winding shaft.

[0024] The above-mentioned first winding turret receives and changes the roll process and related structures for odd-numbered material strips, and the second winding turret receives and changes the roll process and related structures for even-numbered material strips are similar to this, and are specifically described as follows:

[0025] A rotatable second rotating frame 24 is installed on the frame 1, which includes two parallel Z-shaped arms 2401. One end of the Z-shaped arm 2401 is installed on the frame 1 via the second mounting shaft 2402, and the other end is installed with a third support roller 2403 and a fourth support roller 2404. The Z-shaped arm 2401 is also connected to the second cylinder 2409. The Z-shaped arm can rotate upward under the push of the second cylinder and can be reset after rotation. A second air knife 2405 is installed between the third support roller 2403 and the fourth support roller 2404. A second material belt channel 2406 is formed between the fourth support roller 2404 and the second mounting shaft 2402. The even-numbered material belt 102 is guided to the second winding rotating frame 6 by the guide roller 2105. In one embodiment of the present invention, the second air knife 2405 includes a guide rod 2407 and a blade 2408 mounted on the guide rod. The blade 2408 is driven by gas to move quickly on the guide rod 2407 to cut the material strip, and then the blade is reset to the opposite direction.

[0026] The second winding turret 6 is mounted on the frame 1, and includes two parallel four-corner support plates 2501, on which the third winding shaft 2502 and the fourth winding shaft 2503 are mounted at two opposite corners, and on the other two opposite corners, the third push-up roller 2504 and the fourth push-up roller 2505 are mounted. The centers of the two four-corner support plates 2501 are mounted on the support plate rotating shaft 2506, which drives the second winding turret 6 to rotate, and the third winding shaft 2502 and the fourth winding shaft 2503 have separate power drives and can rotate independently.

[0027] During winding, the even-numbered material strip 102 is wound onto the reel on the third winding shaft 2502 after passing through the guide roller 104 and the guide roller 2105. The third winding shaft 2502 rotates to wind up. When the preset time is reached and the winding is completed, the second winding bracket rotates counterclockwise to the rear relative position under the control of the PLC control system (that is, the third winding shaft and the fourth winding shaft exchange positions, and the fourth winding shaft is in the winding position at this time). During the rotation, the third push-up roller 2504 pushes up the even-numbered material strip 102, and the third winding shaft 2502 keeps rotating. Figure 1In the state shown, the second cylinder 2409 then pushes the second rotating frame to rotate upwards, at which time the fourth support roller lifts the even-numbered tape upwards and contacts the reel on the fourth reel. The reel of the fourth reel is coated with glue, which can stick the tape. Therefore, at the same time, the even-numbered tape 102 contacts the fourth support shaft and the third support shaft at the same time, that is, a plane is formed between the third and fourth support shafts. At this time, the second air knife 2405 is actuated, so that the blade 2408 moves from one end to the other end on the guide rod 2407, cutting off the even-numbered tape 102, and then the blade 2408 is reset. In this way, the fourth reel starts to rewind, and the third reel rewinds the tail of the cut even-numbered tape, and then the third reel stops rotating. At this time, the material roll can be removed and replaced with a new reel for the next rewinding. During specific control, the second air knife can be made to contact the second contact point at the same time after cutting off the even-numbered material strips. The PLC control system obtains the contact and starts timing. According to the preset time for filling up the material strips, the second winding turret is driven to rotate and the second cylinder is driven to move and drive the second air knife to complete the re-cutting of the material strips.

[0028] In the above structure, the surface of the fourth support shaft can be made of a cushioning material such as rubber, so that it has cushioning properties when in contact with the reel on the fourth winding shaft.

[0029] The above actions are all carried out under the drive of the drive system, and various transmissions can be performed through electrodes and chains. A high degree of automation can be achieved using a PLC control system. Since the drive and control are easy to implement and can be designed by technicians in this field, they will not be described in detail here.

[0030] This embodiment is only an illustration of the concept and implementation of the present invention, and does not limit it. Under the concept of the present invention, technical solutions that have not been substantially changed are still within the scope of protection.
