Description

Technical Field

[0001] The present invention relates to the technical field of quilt cutting equipment, and in particular to a continuous quilt cutting device based on a storage function and a working method. Background Art

[0002] The production of quilts generally requires cotton grabbing and loosening, cleaning and removing impurities, mixing and loosening, air flow cleaning, air flow conveying, combing and removing impurities, web forming, cotton laying and conveying, mesh yarn covering, shaping and grinding. Finally, the ground quilt is cut into the required length by cutting equipment, for example, 1.8 meters, 2.0 meters, and 2.2 meters long quilts.

[0003] The entire quilt production process is carried out continuously, and cutting takes a certain amount of time. Therefore, in order to ensure that the cutting process does not affect the continuous operation of the upstream equipment, it is generally necessary to set up a temporary storage mechanism upstream of the cutting equipment. The quilt transported from the upstream during the cutting process can be temporarily stored through the temporary storage mechanism, and the temporarily stored quilt can be transported to the cutting equipment after the downstream quilt is cut and taken away. Repeating the above steps can realize continuous cotton cutting operation.

[0004] Although the temporary storage mechanism in the prior art can temporarily store the quilt transported from upstream, it is difficult to quickly transport the temporarily stored quilt downstream, that is, the speed at which the temporary storage mechanism transports the quilt to the downstream cutting device is relatively slow (the reason is that if the traction roller group rotates too fast, the traction roller and the quilt will slip. If slipping occurs, the calculation of the quilt length will be inaccurate. For example, when slipping occurs, the length of the quilt actually transported to the downstream cutting device will be shorter than the actual required length, for example, the required length is 2 meters, but the length transported to the downstream will be shorter than 2 meters, because when slipping, the meter wheel connected to the traction roller is running, but the quilt is not transported downstream due to the slipping problem, resulting in the meter wheel idling and counting). In order to accommodate the slow downstream transportation of the temporary storage mechanism, the operating speed of the equipment in the upstream process steps can only be reduced to a certain extent, resulting in a decrease in the overall production efficiency of the quilt. Summary of the invention

[0005] The purpose of the present invention is to enable the quilts stored in the temporary storage mechanism to be quickly transported downstream and improve the overall production efficiency of the quilts, and to propose a continuous cotton cutting device and working method based on the storage function.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A continuous cotton cutting device based on storage function comprises a first traction roller group, a second traction roller group, a third traction roller group and a cutting mechanism which are sequentially arranged along the conveying direction of the quilt; a first pull-down assembly capable of tightening the quilt is arranged between the first traction roller group and the second traction roller group; a second pull-down assembly capable of tightening the quilt is arranged between the second traction roller group and the third traction roller group; and the second traction roller group is connected to a meter wheel through transmission.

[0008] A clamping mechanism is arranged between the second traction roller group and the third traction roller group, and the clamping mechanism can clamp the quilt to fix the relative position of the quilt between the clamping mechanism and the second traction roller group and the second traction roller group.

[0009] The third traction roller group includes a first roller, a second roller, and a detection mechanism. The quilt is clamped between the first roller and the second roller. The friction coefficient between the first roller and the quilt is greater than the friction coefficient between the second roller and the quilt. The second roller is transmission-connected to the first rotating motor. The detection mechanism can detect the operating status of the first roller and the second roller. When it is detected that the second roller is moving and the first roller is stationary, the first rotating motor stops.

[0010] The clamping mechanism is fixedly installed with a connecting rod, and the connecting rod is rotatably connected to the second traction roller group. The third traction roller group includes a first rotating roller and a second rotating roller. The quilt is clamped between the first rotating roller and the second rotating roller. The second rotating roller is transmission-connected to the first rotating motor, and the first rotating motor is electrically connected to the first trigger. The rotation radius of the clamping mechanism around the connecting rod is defined as the turning radius. The first trigger is located on the turning radius. When the clamping mechanism hits the first trigger, the first rotating motor is turned off.

[0011] The first pull-down assembly includes a first pressure roller and a first counterweight, wherein the first pressure roller is rotatably connected to the first counterweight, the first pressure roller is supported above the quilt, and the first counterweight is suspended below the first pressure roller and located below the quilt.

[0012] The second pull-down assembly includes a second pressure roller and a second counterweight, wherein the second pressure roller is rotatably connected to the second counterweight, the second pressure roller is supported above the quilt, and the second counterweight is suspended below the second pressure roller and located below the quilt.

[0013] The weight of the second counterweight member gradually increases from light to heavy when ascending, and the weight of the second counterweight member remains unchanged or gradually increases from light to heavy when descending.

[0014] The second counterweight member includes a magnetic attraction member, a counterweight chain, an electromagnet, and a support platform. The second pressure roller is rotatably connected to the magnetic attraction member. The counterweight chain is suspended below the second pressure roller or below the magnetic attraction member. When the second pressure roller moves downward, the counterweight chain can gradually be supported on the support platform. The electromagnet is located below the magnetic attraction member and can magnetically attract the magnetic attraction member when the electromagnet is energized.

[0015] The second pressure roller is made of a light hard material, and the counterweight chain is a metal chain.

[0016] A working method of a continuous cotton breaking device based on a storage function, the working method of the continuous cotton breaking device comprising the following steps:

[0017] The upstream quilt is continuously pulled by the first pulling roller group to move toward the second pulling roller group;

[0018] The quilt between the first traction roller group and the second traction roller group is tightened by the first pull-down assembly, and the quilt between the first traction roller group and the second traction roller group is defined as the first quilt;

[0019] The first quilt is pulled between the second traction roller group and the third traction roller group according to the set length by the second traction roller group, and the quilt between the second traction roller group and the third traction roller group is tightened by the second pull-down assembly, and the weight of the second pull-down assembly gradually increases from light to heavy when it rises, and remains unchanged or gradually increases from light to heavy when it descends. After the quilt reaches the set length, the second traction roller group stops moving, and the quilt of the set length is defined as the second quilt;

[0020] The second quilt is quickly transported to the cutting station of the cutting mechanism through the third traction roller group.

[0021] The present invention proposes a continuous cotton cutting device and working method based on storage function, which has the beneficial effect that: the second traction roller group stops moving after pulling the quilt to a set length at a normal operating speed, and the second quilt is quickly transported to the cutting station of the cutting mechanism through the third traction roller group. Because the length of the second quilt has been determined by the second traction roller group, there is no need to consider the slipping problem or calculate the length when the third traction roller group quickly transports the second quilt. The second quilt is transported to the end, which can ensure that the quilt length is accurate and the quilt is quickly transported to the cutting station. During the cutting process, the second traction roller group repeats the above steps to transport the second quilt of a fixed length again. In the entire quilt production process, since the cutting process at the end can be accelerated, the preceding process can also be appropriately accelerated, and the efficiency of the entire quilt production can also be improved.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1-Figure 2 A continuous cotton cutting device based on storage function comprises a first traction roller group 1, a second traction roller group 2, a third traction roller group 3, and a cutting mechanism 4 which are sequentially arranged along the conveying direction of the quilt. A first pull-down component 15 capable of tightening the quilt is arranged between the first traction roller group 1 and the second traction roller group 2. A second pull-down component 17 capable of tightening the quilt is arranged between the second traction roller group 2 and the third traction roller group 3. The pull-down component is used to put the temporarily stored quilt in a tightened state to avoid the problem of traction deviation caused by loose quilt. The second traction roller group 2 is transmission-connected to the meter wheel.

[0027] When the device is working, the quilt processed upstream is continuously transported downstream through the first traction roller group 1 and stored between the first traction roller group 1 and the second traction roller group 2. The quilt in this interval is defined as the first quilt. The first quilt is pulled downstream by the second traction roller group 2 with a metering function and reaches a set length. The quilt of the set length is defined as the second quilt. The second traction roller group 2 stops moving after pulling the quilt to the set length at a normal operating speed (wherein the normal operating speed refers to a rotation speed based on no slipping), and the second quilt is quickly transported to the cutting mechanism 4 through the third traction roller group 3. At the cutting station, because the length of the second quilt has been determined by the second traction roller group 2, the third traction roller group 3 does not need to consider the slipping problem or calculate the length when quickly transporting the second quilt. The second quilt is transported to the end, which can ensure that the quilt length is accurate and the quilt can be quickly transported to the cutting station. During the cutting process, the second traction roller group 2 repeats the above steps and transports the second quilt of fixed length again. In the entire quilt production process, since the cutting process at the end can be accelerated, the preceding process can also be appropriately accelerated, and then the efficiency of the entire quilt production can also be improved.

[0028] refer to Figure 2 A clamping mechanism 8 is arranged between the second traction roller group 2 and the third traction roller group 3. The clamping mechanism 8 can clamp the quilt so that the relative position of the quilt between the clamping mechanism 8 and the second traction roller group 2 and the second traction roller group 2 is fixed. After the second traction roller group 2 conveys the second quilt of a fixed length, the clamping mechanism 8 clamps the quilt to prevent the quilt from slipping out from between the second traction roller group 2 that is not moving due to excessive pulling by the third traction roller group 3.

[0029] The clamping mechanism 8 can adopt an electromagnetic clamping mechanism, and two magnetic blocks are set. The quilt is located between the two magnetic blocks. When power is turned on, the two magnetic blocks magnetically clamp the quilt, and the quilt is released when power is turned off.

[0030] As an embodiment, the third traction roller group 3 includes a first roller 31, a second roller 32, and a detection mechanism. The quilt is clamped between the first roller 31 and the second roller 32. The friction coefficient between the first roller 31 and the quilt is greater than the friction coefficient between the second roller 32 and the quilt. The second roller 32 is connected to the first rotating motor. The detection mechanism can detect the operating status of the first roller 31 and the second roller 32. When it is detected that the second roller 32 moves and the first roller 31 is stationary, the first rotating motor stops. When the device is in use, since the quilt is clamped between the first roller 31 and the second roller 32, the second roller 32 is driven to rotate by the first rotating motor, so that the quilt is conveyed downstream under the clamping action of the first roller 31 and the second roller 32. When the second quilt is conveyed, there is no excess quilt to be conveyed by the second traction roller group 2 and the third traction roller group 3. At this time, the second rotating motor drives the second rotating roller to continue to operate and slip with the quilt. Since there is no residual quilt, the first rotating roller will not continue to rotate. At this time, the detection mechanism can detect that the first rotating roller 31 and the second rotating roller 32 are in two different operating states, that is, the first rotating roller is stationary and the second rotating roller is rotating. In this way, it is judged that the second quilt has been conveyed, the first rotating motor stops running, and the third traction roller group 3 stops the traction action.

[0031] As another embodiment, refer to Figure 1 , Figure 2 The clamping mechanism 8 is fixedly installed with the connecting rod 7, and the connecting rod 7 is rotationally connected with the second traction roller group 2. The third traction roller group 3 includes a first rotating roller 31 and a second rotating roller 32. The quilt is clamped between the first rotating roller 31 and the second rotating roller 32. The second rotating roller 32 is transmission-connected to the first rotating motor. The first rotating motor is electrically connected to the first trigger 14. The rotation radius of the clamping mechanism 8 around the connecting rod 7 is defined as the turning radius. The first trigger 14 is located on the turning radius. When the clamping mechanism 8 hits the first trigger 14, the first rotating motor is turned off.

[0032] refer to Figure 2When there is a surplus of quilt between the second traction roller group 2 and the third traction roller group 3, the quilt between the second traction roller group 2 and the third traction roller group 3 is in a V-shaped structure. At this time, the clamping mechanism 8 is in a state away from the first trigger 14. When the third traction roller group 3 transports the second quilt downstream, the quilt in the V-shaped structure is gradually flattened, and the clamping mechanism 8 is driven to rotate around the rotation radius of the connecting rod 7. When the quilt is straightened, the quilt between the second traction roller group 2 and the third traction roller group 3 is in a state of tending to be straight, and the clamping mechanism 8 hits the first trigger. At this time, it is determined that the second quilt is transported and the first rotating motor is turned off. The first trigger in the device can be a contact switch, a micro switch, a proximity sensor and other components, as long as it can achieve the above-mentioned determination effect. Of course, it can also be used in combination with a controller to receive the signal generated by the first trigger through the controller, and then control the first rotating motor to move.

[0033] The first pull-down assembly 15 includes a first pressing roller 5 and a first counterweight 6. The first pressing roller 5 is rotatably connected to the first counterweight 6. The first pressing roller 5 is supported above the quilt. The first counterweight 6 is suspended below the first pressing roller 5 and is located below the quilt. The first counterweight 6 generates a downward pulling force on the first pressing roller, and the first pressing roller generates a downward pulling force on the quilt, so that the quilt between the adjacent traction roller groups is tightened.

[0034] The second pull-down assembly 17 includes a second pressing roller 9 and a second counterweight 16. The second pressing roller 9 is rotatably connected to the second counterweight 16. The second pressing roller 9 is supported above the quilt, and the second counterweight 16 is suspended below the second pressing roller 9 and is located below the quilt. Similarly, the second counterweight 16 generates a downward pulling force on the second pressing roller 9, and the quilt between the adjacent pulling roller groups is tightened by the second pressing roller 9.

[0035] As an implementation mode, the weight of the second counterweight 16 of the device gradually changes from light to heavy when it rises, and the second counterweight 16 is overall lighter in the early stage of rising, so that the third traction roller group 3 can be used to transport the quilt downstream faster. Since the weight of the second counterweight 16 gradually changes from light to heavy when it rises, that is, as the second quilt gradually decreases, the second counterweight gradually becomes heavier. The second quilt gradually decreases and the counterweight gradually becomes heavier in order to gradually increase the traction force exerted on the third traction roller group 3. The third traction roller group 3 gradually changes from fast operation to normal speed operation. In this way, after the second quilt is transported, the first rotating motor can be stopped more timely. The reason is that the rotational inertia is relatively large during fast rotation. If the load is small, even if the power is immediately cut off, the second rotating roller will rotate a little under the action of inertia. In this way, the third traction roller group 3 can quickly pull the quilt to the downstream in the early stage and can quickly stop the movement in the later stage. Since the second counterweight 16 has become heavier when it rises, the weight of the second counterweight 16 remains unchanged or gradually changes from light to heavy when it descends, which can ensure the tightening effect on the quilt.

[0036] In order to achieve the above effects, as an implementation method, refer to Figure 1 , Figure 2 The second counterweight 16 includes a magnetic attraction member 10, a counterweight chain 11, an electromagnet 12, and a support platform 13. The second pressure roller 9 is rotatably connected to the magnetic attraction member 10. The counterweight chain 11 is suspended below the second pressure roller 9 or below the magnetic attraction member 10. When the second pressure roller 9 moves downward, the counterweight chain 11 can gradually be supported on the support platform 13. The electromagnet 12 is located below the magnetic attraction member 10 and can magnetically attract the magnetic attraction member 10 when the electromagnet 12 is energized.

[0037] When the third traction roller group 3 pulls the second quilt to be transported downstream, the electromagnet 12 is powered off, and the magnetic attraction disappears. Figure 2 , the quilt between the second traction roller group 2 and the third traction roller group 3 is gradually flattened, the second pressing roller gradually rises, and the second pressing roller 9 pulls the counterweight chain to gradually separate from the supporting platform 13, that is, during the rising process of the second pressing roller 9, the counterweight chain pulled below gradually increases, and the counterweight below the second pressing roller 9 also gradually increases;

[0038] When the third traction roller group 3 stops running and the second traction roller group 2 is required to convey the second quilt of fixed length, refer to Figure 1 , the electromagnet is energized, and the electromagnet generates a downward magnetic attraction force on the magnetic attraction member 10. As the second pressure roller 9 gradually moves downward, the counterweight chain suspended below it is gradually supported on the support platform 13, that is, the weight of the counterweight chain gradually decreases, but the magnetic attraction member 10 gradually moves downward and gets closer and closer to the electromagnet 12, and the magnetic attraction force becomes larger and larger, thereby achieving that the weight of the second counterweight member 16 remains unchanged or gradually changes from light to heavy when descending. The counterweight method of the chain is adopted. On the one hand, because there is basically no loss when the chain is lifted and lowered back and forth in a large range, it is beneficial to extend the service life of the entire device. On the other hand, the chain can provide a stable change force when it gradually rises, so that the pulling force of the third traction roller group 3 when pulling the quilt is uniform and gradually increases, and the rotating motor can gradually adapt to this change. The rotating motor is less impacted, and the wear of internal parts will also be less, which is beneficial to extend the service life of the device.

[0039] The second pressing roller 9 is made of a light hard material, and the counterweight chain 11 is a metal chain. The second pressing roller of the device is overall light, so that the second pull-down assembly is mainly exerted with tension by the second counterweight, which better realizes the adjustment of the tension.

[0040] Some conventional settings are omitted in this device, such as the corresponding guide structure, through which the first pressure roller and the second pressure roller can be stably raised and lowered. Furthermore, a soundproof box can be set at the bottom of the counterweight chain 11 to reduce the noise generated by the chain collision. These conventional settings can be adaptively adjusted by technical personnel in this field according to specific working conditions.

[0041] A working method of a continuous cotton breaking device based on a storage function, the working method of the continuous cotton breaking device comprising the following steps:

[0042] The upstream quilt is continuously pulled by the first pulling roller group 1 to move toward the second pulling roller group 2;

[0043] The quilt between the first traction roller group 1 and the second traction roller group 2 is tightened by the first pull-down assembly 15, and the quilt between the first traction roller group 1 and the second traction roller group 2 is defined as the first quilt;

[0044] The first quilt is pulled between the second traction roller group 2 and the third traction roller group 3 according to the set length by the second traction roller group 2, and the quilt between the second traction roller group 2 and the third traction roller group 3 is tightened by the second pull-down assembly 17, and the weight of the second pull-down assembly 17 gradually increases from light to heavy when it rises, and remains unchanged or gradually increases from light to heavy when it descends. After the quilt reaches the set length, the second traction roller group 2 stops moving, and the quilt of the set length is defined as the second quilt;

[0045] The second quilt is quickly transported to the cutting station of the cutting mechanism 4 through the third traction roller group 3 .

[0046] As an implementation mode, when the first trigger 14 is hit, a first control signal is sent out, and the first control signal can stop the third traction roller group 3 from running and start the cutting mechanism 4 to start cutting; when the cutting mechanism 4 is cutting, a second control signal is sent out, and the second control signal can energize the electromagnet 12, cause the clamping mechanism 8 to release the quilt, and cause the second traction roller group 2 to transport the quilt of a set length and then stop moving; after the cutting mechanism 4 completes cutting, a third control signal is sent out, and the third control signal can de-energize the electromagnet 12, cause the clamping mechanism 8 to clamp the quilt, and cause the third traction roller group 3 to run and transport the quilt to the cutting mechanism 4.

[0047] When the device is working, the first traction roller group 1 continuously transports and stores the quilt in the interval between the first traction roller group 1 and the second traction roller group 2, and the second traction roller group 2 transports the quilt at a uniform speed and according to the set length to the interval driven by the second traction roller group 2 and the third traction roller group 3, and the third traction roller group 3 transports the quilt after the fixed length to the cutting station of the cutting mechanism 4;

[0048] The specific working method is as follows: taking one cutting as an example, after the cutting mechanism 4 completes the cutting, a third control signal is issued, and the electromagnet 12 is powered off through the third control signal, and the magnetic force disappears to reduce the counterweight under the second pressure roller 9, so that the clamping mechanism 8 clamps the quilt to avoid pulling out excess quilts during traction, and the third traction roller group 3 runs quickly to transport the quilt to the cutting mechanism 4. As the fixed-length quilt in the driving interval of the second traction roller group 2 and the third traction roller group 3 is gradually pulled to the cutting station, the V-shaped quilt is gradually straightened, and the clamping mechanism 8 is driven by the quilt to rotate around the rotating shaft of the connecting rod 7, and finally hits the first trigger 14. When the first trigger 14 is hit, a first control signal is issued, and the first control signal can stop the third traction roller group 3 from running and start the cutting work of the cutting mechanism 4. When the cutting mechanism 4 is cutting, a second control signal is issued, and the second control signal can energize the electromagnet 12, release the clamping mechanism 8, and stop the second traction roller group 2 after transporting the set length of the quilt. The normal operation of the device is ensured through mutual feedback between multiple signals.

[0049] As an implementation method, the feedback of each signal can be received and the action of each electrical component can be controlled through a controller, a circuit board, a microcomputer and other devices.

[0050] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technical solution, conception, and design obtained by equivalent replacement or modification of the technical solution and inventive concept of the present invention by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
