Description

Technical Field

[0001] This invention relates to the field of cotton quilt production equipment technology, and in particular to a traction mechanism for a continuous cotton breaking device in cotton quilt production. Background Technology

[0002] The production of cotton quilts generally involves the following steps: cotton opening, cleaning and impurity removal, mixed cotton opening, airflow cleaning, airflow conveying, combing and impurity removal, web forming, cotton laying and conveying, covering with mesh, shaping into a quilt, grinding and forming, and finally cutting the ground cotton quilt into the required length, such as 1.8 meters, 2.0 meters, and 2.2 meters, using cutting equipment.

[0003] The entire cotton quilt production process is continuous, 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, a temporary storage mechanism is generally set up upstream of the cutting equipment. The cotton quilts transported from the upstream during the cutting process are temporarily stored in the temporary storage mechanism. After the cotton quilts are cut and removed downstream, the temporarily stored cotton quilts are transported back to the cutting equipment. Repeating the above steps can achieve continuous cotton cutting operation.

[0004] While existing temporary storage mechanisms can temporarily store quilts transported from upstream, they struggle to quickly transport these quilts downstream. The speed at which the temporary storage mechanism conveys the quilts to the downstream cutting device is relatively slow. This is because if the traction roller assembly operates too quickly, slippage between the traction roller and the quilt can occur. Slippage leads to inaccurate quilt length calculations; for example, the actual length of the quilt delivered to the downstream cutting device may be shorter than required (e.g., 2 meters). This is because while the counting wheel connected to the traction roller is running, the quilt is not being transported downstream due to slippage, causing the counting wheel to spin idly. Furthermore, in related technologies, the quilt tensioning component of the temporary storage mechanism typically uses springs for tensioning, which is detrimental to both quilt tensioning and transport. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that in the current technology, the tensioning component of the temporary storage mechanism for cotton quilts generally uses a spring as the tensioning method, which is not conducive to the tensioning and conveying of cotton quilts. Therefore, this invention proposes a traction mechanism for a continuous cotton breaking device in cotton quilt production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A continuous cotton-cutting device traction mechanism in quilt production includes a third traction roller group and a cutting mechanism. The third traction roller group can transport the quilt to the cutting mechanism. A second pull-down component is provided upstream of the third traction roller group to pull the quilt down and tighten it. The weight of the second pull-down component gradually increases from light to heavy when it rises, and the weight of the second pull-down component remains unchanged or gradually increases from light to heavy when it falls.

[0008] The second pull-down assembly includes a second pressure roller and a second counterweight. The second pressure roller and the second counterweight are rotatably connected. The second pressure roller is supported above the quilt. The second counterweight is suspended below the second pressure roller and located below the quilt. The weight of the second counterweight gradually increases as it rises. The weight of the second counterweight remains unchanged or gradually increases as it falls.

[0009] The second counterweight includes a magnetic attractor, a counterweight chain, an electromagnet, and a support platform. The second pressure roller is rotatably connected to the magnetic attractor. The counterweight chain is suspended below the second pressure roller or below the magnetic attractor. When the second pressure roller moves downward, the counterweight chain can gradually support the support platform. The electromagnet is located below the magnetic attractor, and when the electromagnet is energized, it can magnetically attract the magnetic attractor.

[0010] The second pressure roller is made of a lightweight but rigid material, and the counterweight chain is a metal chain.

[0011] The traction mechanism includes a first traction roller group and a second traction roller group arranged sequentially along the quilt conveying direction. The third traction roller group is located downstream of the second traction roller group. A first pull-down component that can tighten the quilt is provided between the first traction roller group and the second traction roller group. The second traction roller group is driven and connected to a meter wheel.

[0012] A clamping mechanism is provided between the second traction roller group and the third traction roller group. The clamping mechanism can clamp the quilt and fix the relative position of the quilt and the second traction roller group between the clamping mechanism and the second traction roller group.

[0013] The clamping mechanism is fixedly mounted with a connecting rod, which 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 drivenly connected to a first rotary motor. The first rotary motor is electrically connected to a first trigger. The rotation radius of the clamping mechanism around the connecting rod is defined as the radius of rotation. The first trigger is located on the radius of rotation. When the clamping mechanism strikes the first trigger, the first rotary motor is turned off.

[0014] When the first trigger is struck, it sends out a first control signal, which can stop the third traction roller group from operating and start the cutting mechanism from cutting.

[0015] When the cutting mechanism cuts, it sends out a second control signal. The second control signal can energize the electromagnet, cause the clamping mechanism to release the quilt, and cause the second traction roller group to transport the quilt of a set length and then stop moving.

[0016] After the cutting mechanism completes the cutting, it sends a third control signal. The third control signal can de-energize the electromagnet, clamp the quilt with the clamping mechanism, and make the third traction roller group run to transport the quilt to the cutting mechanism.

[0017] The present invention proposes a continuous cotton breaking device traction mechanism in quilt production, which has the following advantages: the weight of the second pull-down component of the device gradually increases from light to heavy when it rises, and the weight of the second pull-down component remains unchanged or gradually increases from light to heavy when it falls. This can better adapt to the working state under different working conditions of the quilt and ensure better tensioning and conveying effects. Attached Figure Description

[0020] In the figure: First traction roller group 1, second traction roller group 2, third traction roller group 3, cutting mechanism 4, first pressure roller 5, first counterweight 6, connecting rod 7, clamping mechanism 8, second pressure roller 9, magnetic attraction component 10, counterweight chain 11, electromagnet 12, support platform 13, first trigger 14, first pull-down assembly 15, second counterweight 16, second pull-down assembly 17, first rotating roller 31, second rotating roller 32. Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Reference Figures 1-2 A continuous cotton cutting device traction mechanism in quilt production includes a third traction roller group 3 and a cutting mechanism 4. The third traction roller group 3 can transport the quilt to the cutting mechanism 4. A second pull-down component 17 is provided upstream of the third traction roller group 3 to pull the quilt down and tighten it. The weight of the second pull-down component 17 gradually increases from light to heavy when it rises, and the weight of the second pull-down component 17 remains unchanged or gradually increases from light to heavy when it falls.

[0023] The second pull-down assembly 17 is initially lighter during its ascent, allowing the third traction roller group 3 to transport the quilt downstream more quickly. As the weight of the second pull-down assembly 17 gradually increases during its ascent, the weight of the second counterweight gradually increases as the second quilt decreases. This gradual decrease in the weight and increase in counterweight is to gradually increase the traction force on the third traction roller group 3. The third traction roller group 3 gradually changes from high-speed operation to normal speed operation. This allows the first rotary motor to stop more promptly after the second quilt is transported. This is because the rotational inertia is relatively large during high-speed rotation. If the load is small, even if the power is immediately cut off, the second rotating roller will still rotate slightly due to inertia. In this way, the third traction roller group 3 can quickly transport the quilt downstream in the early stage and stop moving quickly in the later stage. Since the second pull-down assembly 17 has already become heavier during its ascent, keeping its weight constant or gradually increasing during its descent ensures the tensioning effect on the quilt.

[0024] The second pull-down assembly 17 includes a second pressure roller 9 and a second counterweight 16. The second pressure roller 9 and the second counterweight 16 are rotatably connected. The second pressure roller 9 is supported above the quilt, and the second counterweight 16 is suspended below the second pressure roller 9 and located below the quilt. The weight of the second counterweight 16 gradually increases as it rises, and the weight of the second counterweight 16 remains unchanged or gradually increases as it descends. Specifically, as one embodiment, refer to... Figure 1 , Figure 2 The second counterweight 16 includes a magnetic attraction component 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 component 10. The counterweight chain 11 is suspended below the second pressure roller 9 or below the magnetic attraction component 10. When the second pressure roller 9 moves downward, the counterweight chain 11 can gradually support the support platform 13. The electromagnet 12 is located below the magnetic attraction component 10, and when the electromagnet 12 is energized, it can magnetically attract the magnetic attraction component 10.

[0025] When the third traction roller group 3 pulls the second cotton quilt downstream, the electromagnet 12 is de-energized, and the magnetic attraction disappears. (Reference) Figure 2 The quilt between the second traction roller group 2 and the third traction roller group 3 is gradually flattened, the second pressure roller gradually rises, and the second pressure roller 9 pulls the counterweight chain to gradually detach from the support platform 13. That is, during the process of the second pressure roller 9 rising, the counterweight chain pulled below gradually increases, and the counterweight below the second pressure roller 9 also gradually increases.

[0026] When the third traction roller group 3 stops operating and the second traction roller group 2 needs to convey a fixed length of the second quilt, refer to Figure 1When the electromagnet is energized, it generates a downward magnetic attraction force on the magnetic attraction component 10. As the second pressure roller 9 gradually moves downward, the counterweight chain suspended below it gradually supports the support platform 13, meaning the weight of the counterweight chain gradually decreases. However, as the magnetic attraction component 10 moves downward and gets closer to the electromagnet 12, the magnetic attraction force increases. This ensures that the weight of the second counterweight component 16 remains constant or gradually increases during descent. Using a chain counterweight method has two advantages: firstly, the chain experiences minimal wear during large-amplitude lifting and lowering operations, extending the overall lifespan of the device; secondly, the chain provides a stable force as it gradually rises, resulting in a uniform and gradually increasing pulling force when the third traction roller group 3 pulls the quilt. The rotary motor can gradually adapt to this change, experiencing less impact and less wear on internal components, further extending the device's lifespan.

[0027] The second pressure roller 9 is made of a lightweight but rigid material, and the counterweight chain 11 is a metal chain. The second pressure roller of this device is relatively light overall, so the second pull-down assembly is mainly pulled by the second counterweight, which better allows for the adjustment of the pulling force.

[0028] Some conventional features are omitted in this device, such as the corresponding guide structure, which allows the first and second pressure rollers to rise and fall stably. Furthermore, a soundproof box can be installed at the bottom of the counterweight chain 11 to reduce the noise generated by the chain impact. These conventional features can be adjusted by those skilled in the art according to the specific working conditions.

[0029] The traction mechanism includes a first traction roller group 1 and a second traction roller group 2 arranged sequentially along the quilt conveying direction. A third traction roller group 3 is located downstream of the second traction roller group 2. A first pull-down component 15 that can tighten the quilt is provided between the first traction roller group 1 and the second traction roller group 2. The second traction roller group 2 is driven and connected to the meter wheel.

[0030] The first pull-down assembly 15 includes a first pressure roller 5 and a first counterweight 6. The first pressure roller 5 and the first counterweight 6 are rotatably connected. The first pressure roller 5 is supported above the quilt, and the first counterweight 6 is suspended below the first pressure roller 5 and located below the quilt. The first counterweight 6 generates a downward pulling force on the first pressure roller, which in turn generates a downward pulling force on the quilt, thus tightening the quilt between adjacent traction roller groups.

[0031] When this device is working, the processed cotton quilt is continuously conveyed downstream by the first traction roller group 1 and stored between the first traction roller group 1 and the second traction roller group 2. The cotton quilt in this interval is defined as the first cotton quilt. The second traction roller group 2, which has a meter counting function, pulls the first cotton quilt downstream until it reaches a set length. The cotton quilt of this set length is defined as the second cotton quilt. The second traction roller group 2 stops moving after pulling the cotton quilt to the set length at a normal operating speed (where normal operating speed refers to the rotation speed based on not slipping). The second cotton quilt is then quickly conveyed to the cutting mechanism 4 by the third traction roller group 3. At the cutting station, since the length of the second quilt has already been determined by the second traction roller group 2, the third traction roller group 3 does not need to consider slippage or calculate the length when quickly conveying the second quilt. The second quilt is conveyed to the cutting station quickly while ensuring the accuracy of the quilt length. During the cutting process, the second traction roller group 2 repeats the above steps to convey the second quilt of the fixed length again. In the entire quilt production process, since the final cutting process can be accelerated, the preceding processes can also be appropriately accelerated, thereby improving the overall efficiency of quilt production.

[0032] refer to Figure 2 A clamping mechanism 8 is provided between the second traction roller group 2 and the third traction roller group 3. The clamping mechanism 8 can clamp the quilt and fix the relative position of the quilt between the clamping mechanism 8 and the second traction roller group 2. 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 the non-moving second traction roller group 2 due to excessive pulling by the third traction roller group 3.

[0033] The clamping mechanism 8 can be an electromagnetic clamping mechanism, with two magnetic blocks. The quilt is located between the two magnetic blocks. When the power is on, the two magnetic blocks magnetically clamp the quilt, and when the power is off, the quilt is released.

[0034] In one embodiment, the third traction roller group 3 includes a first rotating roller 31, a second rotating roller 32, and a detection mechanism. The quilt is sandwiched between the first rotating roller 31 and the second rotating roller 32. The coefficient of friction between the first rotating roller 31 and the quilt is greater than the coefficient of friction between the second rotating roller 32 and the quilt. The second rotating roller 32 is driven by a first rotary motor. The detection mechanism can detect the operating status of the first rotating roller 31 and the second rotating roller 32. When the second rotating roller 32 is detected to be moving and the first rotating roller 31 is not moving, the first rotary motor stops operating. When this device is in use, the quilt is sandwiched between the first rotating roller 31 and the second rotating roller 32. The second rotating 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 rotating roller 31 and the second rotating roller 32. When the second quilt is finished being conveyed, there is no extra quilt to convey in 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 rotate and slip with the quilt. Since there is no extra 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. By this method, it is determined that the second quilt has been conveyed, so the first rotating motor stops running and the third traction roller group 3 stops traction.

[0035] As another implementation method, refer to Figure 1 , Figure 2 The clamping mechanism 8 is fixedly mounted with the connecting rod 7, which is rotatably connected to 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 driven to the first rotary motor, which 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 radius of rotation. The first trigger 14 is located on the radius of rotation. When the clamping mechanism 8 strikes the first trigger 14, the first rotary motor is turned off.

[0036] refer to Figure 2When there is excess cotton between the second traction roller group 2 and the third traction roller group 3, the cotton quilt between the second traction roller group 2 and the third traction roller group 3 forms a V-shaped structure. At this time, the clamping mechanism 8 is in a state far away from the first trigger 14. When the third traction roller group 3 conveys the second cotton quilt downstream, the V-shaped cotton quilt is gradually flattened. At this time, the clamping mechanism 8 is driven to rotate around the rotation radius of the connecting rod 7. When the cotton quilt is straightened, the cotton quilt between the second traction roller group 2 and the third traction roller group 3 is in a state of tending to be straight. The clamping mechanism 8 strikes the first trigger, which determines that the second cotton quilt conveying is finished, and the first rotary motor is turned off. The first trigger in this device can be a contact switch, micro switch, proximity sensor or other components, as long as the above determination effect can be achieved. Of course, it can also be used in conjunction with a controller, which receives the signal generated by the first trigger and then controls the first rotary motor to operate.

[0037] In one implementation, when the first trigger 14 is struck, it sends a first control signal, which can stop the third traction roller group 3 from operating and start the cutting mechanism 4 from cutting. When the cutting mechanism 4 is cutting, it sends a second control signal, which can energize the electromagnet 12, loosen the quilt by the clamping mechanism 8, 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 has finished cutting, it sends a third control signal, which can de-energize the electromagnet 12, clamp the quilt by the clamping mechanism 8, and cause the third traction roller group 3 to operate and transport the quilt to the cutting mechanism 4.

[0038] When this device is working, the first traction roller group 1 continuously transports and stores the cotton quilt in the interval between the first traction roller group 1 and the second traction roller group 2. The second traction roller group 2 transports the cotton quilt at a constant 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. The third traction roller group 3 transports the cotton quilt of the set length to the cutting station of the cutting mechanism 4.

[0039] The specific working method is as follows: Taking the completion of one cut as an example, after the cutting mechanism 4 completes the cut, it sends out a third control signal. The third control signal de-energizes the electromagnet 12, and the disappearance of the magnetic force reduces the counterweight under the second pressure roller 9, causing the clamping mechanism 8 to clamp the quilt to prevent the excess quilt from being pulled out during traction. The third traction roller group 3 then rotates rapidly to transport the quilt to the cutting mechanism 4. As the quilt of a fixed length is gradually pulled to the cutting position by the second traction roller group 2 and the third traction roller group 3, the V-shaped quilt is gradually straightened. Driven by the quilt, the clamping mechanism 8 rotates around the shaft of the connecting rod 7 and finally hits the first trigger 14. When the first trigger 14 is hit, it sends out a first control signal. The first control signal can stop the third traction roller group 3 and start the cutting mechanism 4. When the cutting mechanism 4 cuts, it sends out a second control signal. 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. Through the mutual feedback between various signals, the normal operation of this device is ensured.

[0040] As one implementation method, various signals can be received and the operation of various electrical components can be controlled by devices such as controllers, circuit boards, and microcomputers.

[0041] The working method is as follows: the upstream quilt is continuously pulled by the first traction roller group 1 to move towards the second traction roller group 2;

[0042] The first pull-down component 15 is used to tighten the quilt between the first traction roller group 1 and the second traction roller group 2, and the quilt within the interval between the first traction roller group 1 and the second traction roller group 2 is defined as the first quilt.

[0043] The first quilt is pulled to a set length between the second traction roller group 2 and the third traction roller group 3 by the second traction roller group 2. The quilt between the second traction roller group 2 and the third traction roller group 3 is tightened by the second pull-down component 17. The weight of the second pull-down component 17 gradually increases when it rises and remains unchanged or gradually increases when it falls. After the quilt reaches the set length, the second traction roller group 2 stops moving. The quilt of the set length is defined as the second quilt.

[0044] The second quilt is quickly transported to the cutting station of the cutting mechanism 4 by the third traction roller group 3.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes to the technical solution and inventive concept of the present invention within the scope of the technology disclosed in the present invention should be covered within the scope of protection of the present invention.
