Description

Technical Field

[0001] This invention relates to the field of transport and unloading devices, and in particular to a nonwoven fabric transport and unloading device. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth, is made of oriented or random fibers. It is called cloth because it has the appearance and some properties of cloth. In the process of non-woven fabric processing, the rolls of cloth need to be unloaded.

[0003] For example, a patent entitled "Non-woven Fabric Transport and Unloading Device" (patent application number: CN213622367U) discloses a non-woven fabric transport and unloading device. The limiting plate is fixedly installed on the track and is perpendicular to the track at its location. The limiting plate can block the non-woven fabric and prevent it from rolling off during transport. However, in actual use, especially for heavy non-woven fabric rolls, the lateral thrust generated by the roll will be concentrated at the connection between the limiting plate and the track, which can easily cause stress concentration, deformation or even damage at the connection, affecting the efficiency of the transport and unloading device.

[0004] In view of the above-mentioned shortcomings, the present invention aims to create a non-woven fabric transport and unloading device, which makes it more industrially valuable. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the purpose of this invention is to provide a nonwoven fabric transport and unloading device, including an inclined housing and a ring belt, wherein the ring belt is disposed inside the housing and is used to transport fabric rolls;

[0006] Limiting components are provided on the outer ring surface of the belt. The limiting components include a lower baffle and an upper baffle. The upper baffle and the lower baffle are connected to the belt in sequence, and adjacent baffles are rotatably connected by a hinge shaft. A torsion spring is fitted on the hinge shaft. Before unloading, the lower and upper baffles are arranged in a V-shape, and the orientation of the corner where the lower and upper baffles connect is opposite to the moving direction of the limiting component. During unloading, the fabric roll is placed on the ring belt. The fabric roll contacts and squeezes the corner where the lower and upper baffles are connected. The lower and upper baffles unfold under force to form a collinear plate structure. When the lower and upper baffles unfold under force, the torsion spring is compressed. The inertial impact force and lateral thrust of the fabric roll are absorbed through the compression deformation of the torsion spring. Guide channels are provided on both inner walls of the chassis. The guide channels include an upper guide branch, a lower guide branch, and a main channel. The upper guide branch, the lower guide branch, and the main channel are all located on the inner wall of the chassis. The main channel is close to the upwardly inclined end of the chassis, and the upper guide branch and the lower guide branch are located at the lower end of the main channel. As the fabric roll and the limiting component move with the belt, the upper baffle on the limiting component slides in the upper guide channel.

[0007] Preferably, the upper guide channel and the lower guide channel are distributed vertically; The top of the upper baffle is rotatably equipped with a top shaft, and the two ends of the top shaft extend into two guide channels respectively; The heights of the upper and lower guide channels are adapted to the outer diameter of the top shaft.

[0008] Preferably, a guide assembly is provided inside the main channel. The guide assembly includes an inner shaft and a guide plate.

The upper guide branch and the lower guide branch are respectively distributed on both sides of the inner shaft. The guide plate is rotatably mounted on the inner shaft, and the end of the guide plate away from the inner shaft is switched with the top and bottom of the main channel.

[0009] Preferably, a magnetic block is fixedly embedded in the bottom of the guide plate, and an installation groove is provided at the bottom of the main channel. An electromagnet is fixedly installed inside the installation groove, and the magnetic block and the electromagnet cooperate.

[0010] Preferably, the upper guide branch, the lower guide branch at the end away from the main channel, and the main channel at the end away from the upper guide branch are all provided with arc extension portions, and the arc of the arc extension portions corresponds to the arc surface of the end of the ring belt.

[0011] Preferably, the bottom end of the lower baffle is rotatably provided with a bottom shaft, and an mounting plate is fixedly provided on the outer ring surface of the ring belt, with the bottom shaft fixedly mounted on the mounting plate; The inner walls on both sides of the chassis are provided with stabilizing slides, and the two ends of the bottom shaft extend into the two stabilizing slides respectively.

[0012] Preferably, a support frame is fixedly installed at the bottom of the chassis; Both ends of the chassis are equipped with rotating rollers, and a belt is fitted over the outside of the two rotating rollers. A motor is fixedly installed on the outer wall of the chassis, and one of the rotating rollers is fixedly installed on the drive shaft of the motor. When the motor starts, it drives the rotating roller to rotate through the drive shaft, and the rotating roller drives the belt to move.

[0013] Preferably, multiple limiting members are provided, and the multiple limiting members are evenly distributed.

[0014] Preferably, the chassis is provided with a locking mechanism located within the inner ring space enclosed by the ring belt. The locking mechanism includes a horizontal bar, a U-shaped bracket, a tray, and an electric push rod. The horizontal bar is distributed along the inclined direction of the ring belt. Multiple U-shaped brackets and trays are provided, with multiple U-shaped brackets and multiple trays distributed in a one-to-one correspondence. The U-shaped brackets are fixedly connected to the top of the horizontal bar and are distributed perpendicularly to the horizontal bar. The U-shaped brackets are located on the side of the ring belt. The trays are fixedly connected to the side of the horizontal bar. The fixed end of the electric push rod is fixedly installed on the chassis, and one of the trays is fixedly installed on the telescopic end of the electric push rod. The lower panel is fixedly connected to a lug, and the corresponding lug, bottom shaft and U-shaped bracket are engaged.

[0015] Preferably, a diagonal brace is fixedly installed on the side wall of the lower baffle, and the diagonal brace is located in front of the lower baffle in the direction of movement. A pressure plate is fixedly installed at the end of the diagonal brace away from the lower baffle, and the pressure plate abuts against the ring belt.

[0016] By means of the above-described solution, the present invention has at least the following advantages: 1. By setting up limiting components and other structures, the present invention absorbs and disperses the inertial impact force and lateral thrust of the fabric roll through elastic deformation at the moment of fabric roll loading, and quickly switches to a rigid support state to form a three-dimensional mobile interception structure, thereby improving the efficiency of the non-woven fabric transport and unloading device. 2. By setting a guide channel on the inner wall of the chassis and a top shaft at the top of the upper baffle, and a guide component in the guide channel, when the lower baffle and the upper baffle are subjected to the pressure of the fabric roll, the top shaft can enter the upper guide channel to connect and support the top of the limiting component, thereby improving the overall stability of the limiting component. This structure can further improve the load-bearing capacity of the limiting component for the fabric roll, and at the same time, while increasing the height of the limiting component, it can still maintain stable and reliable support for the fabric roll, which can meet the support requirements of higher and heavier fabric rolls, and solve the technical problem of difficult to set high load-bearing and high height baffles on the conveyor belt in traditional technology. 3. The support of the pallet and the locking of the U-shaped bracket work together to form a multi-point support and overall locking structure, which ensures that the limiting parts maintain sufficient rigidity and stability under high load and high height conditions, while also sharing the braking load of the motor, thus improving the overall safety and reliability of the equipment. 4. By setting up structures such as magnetic blocks and electromagnets, the coordination state of the upper guide branch, lower guide branch and main channel can be flexibly controlled, which improves the operational flexibility and adaptability of the device and extends the service life of the distributed buffer system. 5. By setting up structures such as bottom shaft and stabilizing slide, the top of the ring belt is provided with movable support, and the top and bottom of the limiting component can be connected with the chassis, thereby enhancing the stability of the three-dimensional movable interception structure. 6. By setting up structures such as diagonal braces and pressure plates, and utilizing the switchable state of the limiting component, an inclined support structure is formed for the middle section of the limiting component, which further improves the stability of the limiting component. At the same time, its swingable design will not hinder the turning action of the belt, ensuring the smoothness of the belt's cyclic movement.

[0035] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0036] Example 1, the present invention provides as follows Figures 1 to 15 The nonwoven fabric transport and unloading device shown includes a housing 1 and a ring belt 2. Both the housing 1 and the ring belt 2 are inclined in the same direction. The ring belt 2 is located inside the housing 1. The upper end of the housing 1 is the loading end, and the lower end of the housing 1 is the unloading end. When the ring belt 2 moves in a circular motion along the inclined direction of the housing 1, it drives the nonwoven fabric placed on the top of the ring belt 2 from the loading end to move towards the unloading end, thus completing the unloading operation of the nonwoven fabric from the transport vehicle.

[0037] In existing technologies, to prevent nonwoven fabric from sliding randomly on the top of the inclined ring belt 2 and to achieve orderly unloading, baffles, such as partitions, are usually bolted to the outer ring surface of the ring belt 2. These baffles are perpendicular to the ring belt 2. However, to avoid affecting the arc-shaped turning motion at both ends of the ring belt 2, the connection width between the baffles and the ring belt 2 is small, and a rigid direct connection is used. When facing a heavy nonwoven fabric roll 23, the inertial impact force and lateral thrust of the roll 23 cannot be dispersed flexibly and are all concentrated at the connection point between the baffles and the ring belt 2. This easily leads to deformation or damage at the connection point, affecting the conveying efficiency and safety stability of the device. Therefore, this invention sets baffles on the outer ring surface of the ring belt 2. The limiting component 3 includes a lower baffle 301 and an upper baffle 302. The upper baffle 302 and the lower baffle 301 are sequentially connected to the ring belt 2, and adjacent baffles are rotatably connected by a hinge shaft, on which a torsion spring is fitted. When not subjected to other external forces, the lower baffle 301 and the upper baffle 302 are arranged in a V-shape, and the orientation of the corner connecting the lower baffle 301 and the upper baffle 302 is opposite to the moving direction of the limiting component 3. For example, at the top of the ring belt 2, the corner connecting the lower baffle 301 and the upper baffle 302 faces to the right, while the top of the ring belt 2 drives the limiting component 3 to move to the left; at the bottom of the ring belt 2, the corner connecting the lower baffle 301 and the upper baffle 302 faces to the left, while the bottom of the ring belt 2 drives the limiting component 3 to move to the right.

[0038] Guide channels are provided on both inner walls of the chassis 1. The guide channels include an upper guide branch 10, a lower guide branch 11, and a main channel 12. The upper guide branch 10, the lower guide branch 11, and the main channel 12 are all located on the inner wall of the chassis 1. The main channel 12 is close to the loading end of the chassis 1, and the upper guide branch 10 and the lower guide branch 11 are located at the lower end of the main channel 12.

[0039] The specific operating procedure for unloading fabric roll 23 is as follows: The first step is to bring the loading end of chassis 1 close to the loading and unloading door of the transport vehicle; The second step is that the ring belt 2 moves in a circular motion along the inclined direction of the housing 1, and the top of the ring belt 2 runs from the loading end to the loading end. The third step is for the operator to place the fabric roll 23 on the ring belt 2 from the feeding end, with the axial direction of the fabric roll 23 aligned with the width direction of the ring belt 2. After placement, the fabric roll 23 rolls towards the limiting member 3 under its own weight. During this feeding process, the ring belt 2 stops moving briefly. The fabric roll 23 contacts and presses the corner where the lower baffle 301 and the upper baffle 302 are connected, causing the lower baffle 301 and the upper baffle 302 to unfold and form a collinear plate-like structure, forming a rigid support, thereby limiting the position of the fabric roll 23. During this process, both torsion springs deform and work together to form a distributed buffer system to buffer the inertial impact force and lateral thrust of the fabric roll 23. Fourth step, the upper baffle 302 slides in the upper guide support 10. When the ring belt 2 continues to move, it drives the limiting member 3 to move synchronously, forming a three-dimensional moving interception structure in which the bottom end of the limiting member 3 is connected to the ring belt 2 and the top end of the limiting member 3 is connected to the chassis 1. The interception structure provides rigid limiting support for the cloth roll 23. Fifth step, the belt 2 stops moving briefly, and the operator removes the fabric roll 23 from the unloading end and places it on a transfer trolley or other mobile equipment; Step 6: After the limiting member 3 completes the arc turning motion with the ring belt 2 at the unloading end, the top of the upper baffle 302 disengages from the machine box 1, and the lower baffle 301 and the upper baffle 302 reset to the V-shaped distribution and continue to move, completing the unloading operation of the cloth roll 23.

[0040] In summary, by setting up structures such as limiting members 3, the present invention absorbs and disperses the inertial impact force and lateral thrust of the fabric roll 23 through elastic deformation at the moment of feeding, and quickly switches to a rigid support state, forming a three-dimensional mobile interception structure, thereby improving the efficiency of the nonwoven fabric transport and unloading device.

[0041] Reference Figure 5 , Figure 6 , Figure 10 As shown, multiple limiting components 3 are provided, and the multiple limiting components 3 are evenly distributed to achieve continuous unloading.

[0042] Reference Figure 6 , Figure 10 , Figure 11 As shown, a bottom shaft 5 is rotatably mounted on the bottom end of the lower baffle 301. The length of the bottom shaft 5 is greater than the width of the ring belt 2. A mounting plate 4 is fixedly connected to the bottom shaft 5. The mounting plate 4 is fixedly mounted on the outer ring surface of the ring belt 2 by bolts, etc. The torsion spring between the lower baffle 301 and the ring belt 2 is a first torsion spring 8. The first torsion spring 8 is fitted on the bottom shaft 5. One end of the first torsion spring 8 is fixedly connected to the bottom shaft 5, and the other end of the first torsion spring 8 is fixedly connected to the lower baffle 301. When not affected by other external forces, under the elastic support force of the first torsion spring 8, the top of the lower baffle 301 tilts in the opposite direction of the movement of the limiting member 3. The elastic support force of the first torsion spring 8 is large, which can absorb the inertial impact force and lateral thrust of the fabric roll 23 through compression deformation, and also ensure that the lower baffle 301 and other structures will not shake randomly when the ring belt 2 is in cyclical motion.

[0043] Meanwhile, the top of the lower baffle 301 is fixedly connected to the central shaft 7, and the bottom of the upper baffle 302 is rotatably mounted on the central shaft 7. The torsion spring between the upper baffle 302 and the lower baffle 301 is the second torsion spring 9. The second torsion spring 9 is fitted on the central shaft 7, one end of the second torsion spring 9 is fixedly connected to the central shaft 7, and the other end of the second torsion spring 9 is fixedly connected to the upper baffle 302. When not affected by other external forces, under the elastic support force of the second torsion spring 9, the top of the upper baffle 302 tilts in the direction of movement of the limiting member 3. The elastic support force of the second torsion spring 9 is large, which can absorb the inertial impact force and lateral thrust of the cloth roll 23 through compression deformation, and also ensure that the upper baffle 302 and other structures will not shake randomly when the ring belt 2 is in cyclical motion.

[0044] Reference Figure 2 , Figure 6 As shown, a limiting strip 24 is fixedly installed on the side of the top of the lower baffle 301, and the limiting strip 24 is located on the concave side when the lower baffle 301 and the upper baffle 302 are distributed in a V shape. When the lower baffle 301 and the upper baffle 302 are adjusted from a V shape distribution to a collinear distribution, the bottom end of the upper baffle 302 abuts against the limiting strip 24 to achieve the purpose of limiting.

[0045] Reference Figure 2 , Figure 4 , Figure 6 As shown, the lengths of the upper guide branch 10 and the lower guide branch 11 are greater than the length of the main channel 12, and the upper guide branch 10 is located above the lower guide branch 11; the top of the upper baffle 302 is rotatably provided with a top shaft 6, and the two ends of the top shaft 6 extend into the two guide channels respectively.

[0046] It should be noted that the upper guide branch 10, the lower guide branch 11 at the end away from the main channel 12, and the main channel 12 at the end away from the upper guide branch 10 are all provided with arc-shaped extension portions. The arc of the arc-shaped extension portions corresponds to the arc surface of the end of the ring belt 2, which is adapted to the movement trajectory of the top shaft 6. The arc-shaped extension portions penetrate through the end of the housing 1. The arc-shaped extension portions have a large opening, which ensures that the top shaft 6 can quickly enter the interior of the guide channel during the movement of the limiting member 3. The other parts except for the arc-shaped extension portions are rectangular and parallel to the running direction of the top of the ring belt 2.

[0047] When not compressed by the fabric roll 23, if the top shaft 6 enters the interior of the main track 12, the top shaft 6 will fit against the bottom end of the main track 12. The heights of the upper guide track 10 and the lower guide track 11 are adapted to the outer diameter of the top shaft 6, which can constrain and guide the movement trajectory of the top shaft 6, ensuring that the top shaft 6 slides stably along the upper guide track 10 or the lower guide track 11, and avoiding radial shaking or deviation. At the same time, both ends of the top shaft 6 are equipped with wear-resistant bushings, sliding bearings or wear-reducing pads and other wear-resistant structures to reduce the friction and wear between the top shaft 6 and the guide track during the reciprocating sliding process, and improve the running stability of the guiding mechanism.

[0048] Reference Figure 4 , Figure 6 and Figure 9 As shown, in order to control the top shaft 6 to enter the upper guide branch 10 or the lower guide branch 11, a guide assembly is provided in the main channel 12. The guide assembly includes an inner shaft 13 and a guide plate 14. The inner shaft 13 is fixedly installed on the inner wall of the main channel 12. The inner shaft 13 is located at the end of the main channel 12 near the upper guide branch 10. The upper guide branch 10 and the lower guide branch 11 are respectively distributed on both sides of the inner shaft 13. The guide plate 14 is rotatably mounted on the inner shaft 13. The end of the guide plate 14 away from the inner shaft 13 is switched with the top and bottom of the main channel 12.

[0049] A magnetic block 15 is fixedly embedded in the bottom of the guide plate 14, and an installation groove is opened at the bottom of the main channel 12. An electromagnet 16 is fixedly installed inside the installation groove, and the magnetic block 15 and the electromagnet 16 cooperate.

[0050] By setting a guide channel on the inner wall of the chassis 1 and setting a top shaft 6 at the top of the upper baffle 302, and a guide component is provided in the guide channel, when the lower baffle 301 and the upper baffle 302 are subjected to the pressure of the fabric roll 23, the top shaft 6 can enter the upper guide support 10 to connect and support the top of the limiting member 3, thereby improving the overall stability of the limiting member 3. This structure can further improve the load-bearing capacity of the limiting member 3 on the fabric roll 23. At the same time, while increasing the height of the limiting member 3, it can still maintain stable and reliable support for the fabric roll 23, which can meet the support requirements of higher and heavier fabric rolls 23, and solve the technical problem of difficult to set high load-bearing and high height baffles on the conveyor belt in traditional technology.

[0051] The actual working conditions are as follows: Reference Figure 5 The ring belt 2 rotates counterclockwise. When unloading is required, the electromagnet 16 is activated, and the magnetism of the magnetic block 15 and the electromagnet 16 on the side that is close to each other is opposite. Under the action of the attraction force, the end of the guide plate 14 away from the inner shaft 13 abuts against the bottom of the main channel 12, effectively ensuring that the top shaft 6 achieves a smooth transition between the main channel 12 and the upper guide branch channel 10. At this time, the end of the lower guide branch channel 11 close to the main channel 12 is blocked to prevent the top shaft 6 from accidentally entering the lower guide branch channel 11 and affecting the unloading process.

[0052] The operator places the fabric roll 23 onto the ring belt 2 from the feeding end, with the axial direction of the fabric roll 23 aligned with the width direction of the ring belt 2. At this time, the top shaft 6 is in a waiting-to-guide state inside the main channel 12. After placement, the fabric roll 23 rolls towards the adjacent and lower limiting member 3 under its own weight. The fabric roll 23 contacts and presses the corner of the lower baffle 301 and the upper baffle 302. At the same time, guided by the guide plate 14, the top shaft 6 smoothly enters the interior of the upper guide branch 10. The lower baffle 301 and the upper baffle 302 unfold under force to form a collinear plate structure, thereby stabilizing and limiting the fabric roll 23. During this process, the first torsion spring 8 and the second torsion spring 9 cooperate with each other and undergo elastic deformation simultaneously, absorbing the inertial impact force and lateral thrust of the fabric roll 23, preventing the impact force from directly acting on the connection between the limiting member 3 and the ring belt 2, thus protecting the limiting member 3 and the ring belt 2.

[0053] Due to the continuous compression of the cloth roll 23, the top of the limiting member 3 still tends to tilt in its direction of movement. This tilting tendency ensures that the top shaft 6 is always tightly attached to the inner wall of the upper guide support 10, providing suspension support for the top of the limiting member 3. Furthermore, the limiting member 3, the top shaft 6, and the cloth roll 23 move synchronously with the ring belt 2, thereby forming a three-dimensional moving interception structure in which the bottom of the limiting member 3 connects with the ring belt 2 and the top of the limiting member 3 connects with the machine housing 1. This structure has both limiting and buffering functions, preventing the cloth roll 23 from shaking or slipping during the conveying process, and ensuring that the unloading operation is carried out in an orderly and safe manner.

[0054] After the fabric roll 23 is conveyed to the unloading end, the operator removes the fabric roll 23. After the limiting member 3 completes the arc turning motion with the ring belt 2 at the unloading end, the top shaft 6 disengages from the guide channel on the machine box 1. Under the action of the reset elastic force of the first torsion spring 8 and the second torsion spring 9, the lower baffle 301 and the upper baffle 302 reset to the V-shaped distribution and continue to move, completing the unloading operation of the fabric roll 23.

[0055] When the unloading frequency of the cloth roll 23 is low, it is not necessary to place the cloth roll 23 at each limiting member 3. At this time, the electromagnet 16 is activated, and the magnetism of the magnetic block 15 and the electromagnet 16 on the side closest to each other is the same. Under the action of repulsive force, the end of the guide plate 14 away from the inner shaft 13 abuts against the top of the main channel 12, effectively ensuring that the top shaft 6 achieves a smooth transition between the main channel 12 and the lower guide branch channel 11. Specifically, when not squeezed by the cloth roll 23, the lower baffle 301 and the upper baffle 302 maintain a V-shaped distribution state. The top shaft 6 moves from the main channel 12 into the interior of the lower guide branch channel 11. The first torsion spring 8 and the second torsion spring 9 can maintain a natural state, without elastic deformation, and do not need to bear additional load. This zero-force state can reduce the fatigue wear of the first torsion spring 8 and the second torsion spring 9, and extend the service life and maintenance cycle. At the same time, the use of magnetic control does not affect the smooth transition of the top shaft 6 between the main channel 12 and the lower guide branch channel 11.

[0056] In summary, by setting up structures such as magnetic blocks 15 and electromagnets 16, the present invention flexibly controls the coordination state of the upper guide branch 10, the lower guide branch 11 and the main channel 12, thereby improving the operational flexibility and adaptability of the device and extending the service life of the distributed buffer system.

[0057] In addition, an infrared sensor (not shown in the figure) is installed at the corresponding feeding end of the chassis 1, and a controller is set up to connect the infrared sensor and the electromagnet 16. The infrared sensor monitors in real time whether there is a cloth roll 23 placed on the ring belt 2 and the corresponding limiting member 3 at the feeding end, and transmits the detection signal to the controller. The controller determines the unloading frequency according to the detection result, outputs a command to the electromagnet 16 to adjust its magnetic polarity with the magnetic block 15, switches the direction of the guide plate 14, and guides the top shaft 6 into the upper guide branch 10 (when there is a cloth roll 23) or the lower guide branch 11 (when there is no cloth roll 23), adapting to different unloading conditions and ensuring stable operation of the device.

[0058] Reference Figure 2 , Figure 4 , Figure 6 As shown, in order to ensure the stability of the cyclic motion of the ring belt 2, stabilizing slides 17 are provided on both sides of the inner wall of the housing 1. The two ends of the bottom shaft 5 are respectively inserted into the two stabilizing slides 17 for sliding. In actual use, the two ends of the bottom shaft 5 are provided with wear-resistant bushings, sliding bearings or wear-reducing pads and other wear-resistant structures to reduce the friction and wear between the bottom shaft 5 and the stabilizing slides 17 during the reciprocating sliding process.

[0059] Specifically, during the cyclic movement of the ring belt 2, the bottom shaft 5 moves inside the stabilizing slide 17, thereby providing movable support to the top of the ring belt 2 and reducing the pressure of the cloth roll 23 on the ring belt 2; at the same time, it allows the top and bottom ends of the limiting member 3 to dock with the chassis 1, enhancing the stability of the three-dimensional moving interception structure, preventing the limiting member 3 from tilting or deforming due to uneven force, and ensuring the limiting effect of the limiting member 3 on the cloth roll 23.

[0060] It should be noted that both ends of the stabilizing slide 17 are provided with arc-shaped extensions to adapt to the movement trajectory of the bottom shaft 5. The arc-shaped extensions extend through the end of the chassis 1 and have a large opening to ensure that the bottom shaft 5 can quickly enter the stabilizing slide 17 when it moves with the ring belt 2.

[0061] In summary, the present invention provides movable support for the top of the ring belt 2 by setting up structures such as the bottom shaft 5 and the stabilizing slide 17, while enabling the top and bottom of the limiting member 3 to dock with the chassis 1, thereby enhancing the stability of the three-dimensional movable interception structure.

[0062] Reference Figure 1 , Figure 5As shown, a support frame 20 is fixedly installed at the bottom of the chassis 1. The support frame 20 adopts a rigid metal frame structure and is distributed along the length of the chassis 1 to provide stable support for the entire chassis 1 and various components of the device. In actual use, a swivel caster or other moving structure (not shown in the figure) is provided at the bottom of the support frame 20, and the swivel caster is equipped with a braking locking mechanism. This not only makes it easy for operators to flexibly push the device to adjust its placement position according to the unloading requirements, reducing the difficulty of handling, but also allows the swivel caster to be fixed by the locking braking mechanism when the device is working, preventing the device from sliding or shifting. Adjustments can be made according to the specific usage conditions.

[0063] Both ends of the housing 1 are equipped with rotating rollers 18, and the ring belt 2 is fitted around the outside of the two rotating rollers 18. A motor 19 is fixedly installed on the outer wall of the housing 1. The motor 19 is a geared motor adapted to the workshop conditions, which has the characteristics of stable power and convenient speed adjustment. One of the rotating rollers 18 is fixedly installed on the drive shaft of the motor 19. After the motor 19 starts, it can drive the rotating roller 18 to rotate at a uniform speed, thereby driving the ring belt 2 to move smoothly in a circular motion around the two rotating rollers 18 along the inclined direction of the housing 1, providing continuous and stable power support for the conveying and unloading of the fabric roll 23.

[0064] In actual use, a tensioning device is installed inside the casing 1 to tension the ring belt 2, ensuring the smooth operation of the ring belt 2. The tensioning device includes structures such as tensioning wheels. The tensioning device is a common existing technology and will not be described in detail here.

[0065] Reference Figure 7 , Figure 8 , Figure 9 , Figure 12 As shown, considering the long waiting time for the transport trolley to reach the unloading end during the unloading process, when the belt 2 carrying a large number of fabric rolls 23 stops working, the fabric rolls 23 will put a lot of pressure on the belt 2, limiting components 3, etc. To achieve stable support, a locking mechanism is provided on the chassis 1. The locking mechanism is located in the inner circle space enclosed by the belt 2. The locking mechanism includes a horizontal bar 25, a U-shaped bracket 26, a support plate 27, and an electric push rod 28. The horizontal bar 25 is distributed along the inclined direction of the belt 2, and the U-shaped bracket 28 is... Multiple U-shaped card holders 26 and multiple trays 27 are provided. Multiple U-shaped card holders 26 and multiple trays 27 are distributed in a one-to-one correspondence. The U-shaped card holders 26 are fixedly connected to the top of the crossbar 25. The U-shaped card holders 26 are distributed perpendicularly to the crossbar 25 and are located on the side of the ring belt 2. The ring belt 2 does not affect the upward movement of the U-shaped card holders 26. The trays 27 are fixedly connected to the side of the crossbar 25. The fixed end of the electric push rod 28 is fixedly installed on the chassis 1. One of the trays 27 is fixedly installed on the telescopic end of the electric push rod 28.

[0066] The lower baffle 301 is fixedly connected to the side with a lug 29. The lug 29, the bottom shaft 5, and the U-shaped bracket 26 corresponding to the same limiting member 3 are engaged and cooperated. The lug 29, the U-shaped bracket 26, etc. are all made of high-strength materials, such as stainless steel.

[0067] In actual use, when the belt 2, which needs to support a large number of fabric rolls 23, stops working, the limiting member 3 at the top of the belt 2 first aligns with one of the U-shaped brackets 26, and the telescopic end of the electric push rod 28 is extended, causing the crossbar 25 and the U-shaped bracket 26 to move upward at an angle until the support plate 27 abuts against the lower surface of the top of the belt 2, thus providing synchronous support for the belt 2 and the fabric rolls 23, sharing the weight of the fabric rolls 23, and reducing the tension and deformation pressure on the belt 2 itself. At the same time, the ear rod 29 and the bottom shaft 5 are simultaneously inserted into the U-shaped bracket 26, restricting the lower baffle 301 from rotating around the bottom shaft 5, further preventing the limiting member 3 from tilting, swaying, or loosening under load, and ensuring the stability of the limiting member 3 in supporting the fabric rolls 23.

[0068] Furthermore, in the existing structure, when the belt 2 stops working, it usually relies solely on the braking lock of the motor 19 to achieve a shutdown. Long-term heavy-load shutdown can easily cause a large load and impact on the motor 19, affecting the service life of the motor 19 and the operational stability of the equipment. However, the present invention uses a locking mechanism to mechanically lock and provide auxiliary support to the bottom shaft 5, the limiting member 3, and other structures, thereby sharing the braking load of the motor 19 and preventing the motor 19 from bearing the heavy load pressure of the cloth roll 23 and the belt 2 alone.

[0069] In summary, the support of the pallet 27 and the locking of the U-shaped bracket 26 work together to form a multi-point support and overall locking structure, which enables the limiting component 3 to maintain sufficient rigidity and stability under high load and high height conditions, while also sharing the braking load of the motor 19, thereby improving the overall safety and reliability of the equipment.

[0070] Example 2, the present invention provides as follows Figures 14-15 The nonwoven fabric transport and unloading device shown has a diagonal brace 21 fixedly installed on the side wall of the lower baffle 301 to further ensure the stability of the use of the limiting member 3. The diagonal brace 21 is located in front of the lower baffle 301 in the direction of movement. A pressure plate 22 is fixedly installed at the end of the diagonal brace 21 away from the lower baffle 301. The pressure plate 22 has a large contact area.

[0071] During the unloading process, the lower baffle 301 and the upper baffle 302 unfold into a collinear plate structure. At this time, the pressure plate 22 abuts against the outer ring surface of the belt 2, forming an inclined support structure for the middle section of the limiting member 3, further improving the stability of the limiting member 3. At the same time, when the limiting member 3 moves in an arc with the belt 2 at the loading end and unloading end, since the lower baffle 301 and the upper baffle 302 are not squeezed, the pressure plate 22 will not contact the outer ring surface of the fabric roll 23, ensuring the stable movement of the belt 2.

[0072] This embodiment is suitable for continuous, high-frequency unloading conditions. Long-term high-frequency conveying of the cloth roll 23 can easily lead to fatigue wear of the limiting component 3. The supporting effect of the inclined support frame 21 can extend the service life of the limiting component 3. The inclined support frame 21 and the lower baffle 301 can also be fixed by a detachable assembly method, which is convenient for later maintenance and replacement, and can be adjusted according to the specific use.

[0073] In summary, by setting up structures such as the inclined support frame 21 and the pressure plate 22, and utilizing the switchable state of the limiting member 3, the present invention forms an inclined support structure for the middle section of the limiting member 3, which further improves the stability of the limiting member 3. At the same time, its swingable design will not hinder the turning action of the ring belt 2, ensuring the smoothness of the ring belt 2's cyclic movement.

[0074] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
