Description

Technical Field

[0001] This utility model relates to the field of extrusion molding equipment technology, and in particular to a felt conveying mechanism. Background Technology

[0002] As extruded products achieve increasingly complex cross-sections, single-yarn structures are no longer sufficient to meet production demands. With the widespread use of felt fabric, frequent quality issues have arisen due to felt fabric stacking and directional instability during transport. Uneven wall thickness in extruded products is the most significant problem. Current on-site felt fabric conveying mechanisms only meet the basic function of conveying the felt; they lack the necessary conveying stability and preventative measures against felt stacking.

[0003] Currently, similar products on the market achieve precise conveying control through electromagnetic resistance. Electromagnetic resistance conveying mechanisms require an external power supply, are expensive, and pose a fire risk. Existing conveying mechanisms use a fixed circular shaft passing through the center of a felt roll. The felt roll rotates around the fixed shaft under external force to achieve the conveying function, lacking axial positioning capabilities. The felt roll exhibits axial movement when passively rotated. Furthermore, because the felt roll itself lacks tension, uneven conveying speed and stacking problems can occur after continuous stretching. Utility Model Content

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention provide a felt conveying mechanism that offers advantages such as stable conveying and prevention of stacking.

A mounting backplate is provided at the first end of the fixed base, and a fixed bearing is provided at the second end of the fixed base. The tensioning mechanism includes a fixed tensioning wheel and a rotating roller. The first end of the rotating roller passes through the fixed bearing and is pivotally connected to the mounting backplate. A pair of fixed tensioning wheels are provided on the rotating roller to constrain the felt. The fixed tensioning wheels are located on the side of the fixed bearing away from the mounting backplate. The damping mechanism is arranged on the mounting backplate and abuts against the first end of the rotating roller to provide stable rotational damping to the rotating roller.

[0006] The felt conveying mechanism according to this utility model has the advantages of stable conveying and prevention of stacking. This invention uses a damping mechanism without external power supply to achieve precise conveying control to meet production needs and ensure stable supply direction of the felt during conveying. Simultaneously, the tensioning mechanism provides tension to the felt and maintains the conveying speed. The equipment is easy to maintain and replace, meets fire and explosion prevention requirements in workshops, and poses minimal safety hazards.

[0021] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] According to an embodiment of the present invention, the felt conveying mechanism includes a fixed base 1, a tensioning mechanism, and a damping mechanism. A mounting back plate 2 is provided at the first end of the fixed base 1, and a fixed bearing 3 is provided at the second end of the fixed base 1. The tensioning mechanism includes fixed tensioning wheels 5 and a rotating roller 4. The first end of the rotating roller 4 passes through the fixed bearing 3 and is pivotally connected to the mounting back plate 2. A pair of fixed tensioning wheels 5 are provided on the rotating roller 4 to constrain the felt. The fixed tensioning wheels 5 are located on the side of the fixed bearing 3 away from the mounting back plate 2. The damping mechanism is arranged on the mounting back plate 2 and abuts against the first end of the rotating roller 4 to provide stable rotational damping to the rotating roller 4. The fixed base 1 serves to support and fix other components. The mounting back plate 2 is used to fix the damping mechanism and the rotating roller. The fixed bearing 3 is used to limit the rotational roller 4 to prevent it from deviating or tilting, ensuring that it can rotate smoothly and steadily.

[0023] The damping mechanism provides stable damping for the rotating roller 4, which can effectively control the tension changes of the felt during the conveying process and prevent the felt from wrinkling, loosening or breaking due to excessive or insufficient tension, thus achieving a stable supply of felt during the conveying process.

[0024] The tensioning mechanism provides tension to the felt and maintains the conveying speed, preventing uneven conveying speed and stacking of the felt due to continuous stretching caused by a lack of tension. A pair of fixed tensioning wheels 5 of the tensioning mechanism are used to restrain the felt, ensuring that the felt stays on the correct path during conveying and preventing the felt from deviating or slipping.

[0025] In some embodiments, the felt conveying mechanism further includes a limiting mechanism, which includes a flange and a locking bolt. The flange is sleeved on the rotating roller 4, and the locking bolt passes through the flange and is connected to the rotating roller 4.

[0026] Specifically, the limiting mechanism is used to solve the problem of axial movement of the felt cloth when it is passively rotated. The flange is arranged on the rotating roller 4 to prevent the felt cloth from moving axially, thus achieving axial positioning. The locking bolt is threadedly connected to the rotating roller 4, which facilitates the adjustment of the flange position to achieve adjustment of the axial positioning position.

[0027] In some embodiments, a limiting groove is provided on the rotating roller 4, which is arranged around the circumference of the rotating roller 4 and enters in conjunction with the locking bolt.

[0028] Specifically, the limiting groove is an annular groove arranged around the rotating roller 4, facilitating the entry of the locking bolt. Regardless of the angle from which the locking bolt approaches the rotating roller 4, it can smoothly enter the limiting groove. The locking bolt's entry into the limiting groove allows for rapid positioning, eliminating the need for multiple manual adjustments and facilitating quick installation or replacement of the roll material. After the locking bolt enters the limiting groove, tightening the bolt securely fixes the flange to the rotating roller 4, thus limiting the movement of the rotating roller 4.

[0029] In some embodiments, the width of the limiting groove is greater than the diameter of the locking bolt and less than the thickness of the flange.

[0030] Specifically, the width range of the limiting groove ensures that the locking bolt can effectively enter the limiting groove to achieve the limiting function, while avoiding interference between the flange and the limiting groove, thus ensuring the stability and reliability of the limiting mechanism. If the width of the limiting groove is smaller than the diameter of the locking bolt, the bolt will not be able to enter the groove, causing the limiting function to fail. During installation, the flange needs to fit tightly against the rotating roller 4. If the limiting groove is too wide, the flange may sink into the limiting groove, preventing proper installation of the flange and even damaging the rotating roller 4 or the flange.

[0031] Optionally, anti-slip textures or anti-slip protrusions can be provided on the inner surface of the limiting groove to increase the friction between the locking bolt and the limiting groove, prevent the locking bolt from loosening when the rotating roller 4 rotates at high speed, and further improve the stability of the limiting.

[0032] In some embodiments, the fixed base 1 includes a connecting plate 7, an adjusting column 9, and a support plate 8. The support plate 8 is connected to the mounting back plate 2 and the fixed bearing 3, and the adjusting column 9 passes through the support plate 8 and is connected to the connecting plate 7.

[0033] Specifically, the connecting plate 7 can be fixed to the ground or other equipment to provide a stable installation foundation for the conveying mechanism. The support plate 8 is the upper structure of the fixed base 1, used to support the mounting back plate 2 and the fixed bearing 3. It is connected to the mounting back plate 2 and the fixed bearing 3 to ensure the structural stability of the entire conveying mechanism. The adjusting column 9 connects the support plate 8 and the connecting plate 7. Changing the size of the protrusion of the adjusting column 9 from the support plate 8 and the connecting plate 7 can change the distance between the support plate 8 and the connecting plate 7, and adjust the height position of the mounting back plate 2 and the fixed bearing 3 on the support plate 8. The adjusting column 9 makes the connecting plate 7 and the support plate 8 form a detachable frame, which is convenient for equipment installation and maintenance. The two ends of the adjusting column 9 are threaded to fix it to the support plate 8 and the connecting plate 7 through screws. The mounting back plate 2 and the support plate 8 are fixed by a threaded connection, which facilitates the disassembly and replacement of the mounting back plate 2.

[0034] Optionally, the adjusting column 9 is provided with a scale to facilitate quick manual adjustment of the height of the support plate 8.

[0035] In some embodiments, guide grooves are provided on the support plate 8 and the connecting plate 7 respectively. The guide grooves extend along the axial direction of the rotating roller 4, and the two ends of the adjusting column 9 enter the guide grooves of the support plate 8 and the connecting plate 7 respectively.

[0036] Specifically, the guide groove extends along the axial direction of the rotating roller 4, and its main function is to provide a movement path for the adjusting column 9. Both ends of the adjusting column 9 enter the guide grooves of the support plate 8 and the connecting plate 7 respectively, ensuring that the movement direction of the adjusting column 9 is restricted when adjusting its height or position, allowing it to move only axially. This facilitates quick and easy changes to the position and height of the adjusting column 9, improving efficiency.

[0037] The width and depth of the guide groove need to match the dimensions of the adjusting column 9 to ensure smooth movement of the adjusting column 9 within the guide groove, while preventing the adjusting column 9 from wobbling or becoming loose within the guide groove. The guide groove provides a stable movement path for the adjusting column 9, reducing friction and wear between the adjusting column 9 and other components, and extending the service life of the equipment. The cooperation between the guide groove and the adjusting column 9 allows for convenient adjustment of the equipment height.

[0038] In some embodiments, a plurality of adjusting columns 9 are used between the support plate 8 and the connecting plate 7 to form a clamping space, and two adjusting columns 9 are arranged in each guide groove for clamping the device.

[0039] Specifically, the clamping space is used to clamp other equipment for easy fixation. The support plate 8 and the connecting plate 7 abut against other equipment to complete the fixation. The adjusting column 9 moves in the guide groove until it abuts against other equipment, which can fix the base 1 to other equipment and ensure stability.

[0040] In some embodiments, the damping mechanism includes a rotary damper 6, which is arranged on the side of the mounting back plate 2 away from the fixed bearing 3.

[0041] Specifically, the rotating damper 6 provides stable damping via hydraulic pressure, eliminating the need for an external power supply and ensuring fire and explosion safety in the production workshop. The damper generates heat during operation; positioning it away from the fixed bearing 3 increases heat dissipation space, facilitating heat dissipation for the rotating damper 6 and simplifying its adjustment and maintenance. The rotating damper 6 is fixed to the mounting back plate 2 with bolts.

[0042] In some embodiments, a heat sink is provided on the rotary damper 6, and the heat sink is a semiconductor cooling chip.

[0043] Specifically, the cooling end of the thermoelectric cooler is attached to the rotating damper 6, which can quickly reduce the temperature of the rotating damper 6. The fast cooling speed of the thermoelectric cooler can control the operating temperature of the rotating damper 6 within a reasonable range, avoid performance degradation or damage caused by overheating, and extend the service life of the equipment.

[0044] Optionally, a fan can be placed at the heat dissipation end of the thermoelectric cooler to increase air convection and improve heat dissipation.

[0045] In some embodiments, the felt conveying mechanism further includes a torque sensor arranged on the rotating roller 4 to detect the torque of the rotating roller 4.

[0046] Specifically, a torque sensor is mounted on the rotating roller 4. Based on the torque signal detected by the sensor, the damping force output by the rotary damper 6 is adjusted. The torque sensor can detect changes in the torque of the rotating roller 4 in real time. By monitoring these changes, the damping force of the rotary damper 6 can be adjusted according to the deviation between the actual measured value and the set value, ensuring that the tension of the felt fabric during transport remains within the set range and reducing transport problems caused by tension fluctuations. The torque sensor can also detect abnormal torque changes in a timely manner, such as felt fabric knotting or sudden tension changes, issuing early warnings to prevent equipment damage or production interruptions.

[0047] Optionally, the torque sensor is positioned at one end of the rotating roller 4 adjacent to the rotating damper 6, which facilitates the detection of torque changes and minimizes the influence of the rotating roller 4 and other equipment. Positioning the torque sensor at one end of the rotating roller 4 adjacent to the rotating damper 6 can reduce measurement errors and improve measurement accuracy.

[0048] In some embodiments, the felt conveying mechanism further includes a controller, which is electrically or communicatively connected to the torque sensor and the rotary damper 6 to control the output damping force of the rotary damper 6.

[0049] Specifically, the controller can also be a control center with remote communication or electrical connection. On the one hand, the controller can obtain the torque of the rotating roller 4 in real time to understand the working condition of the felt conveying mechanism. On the other hand, it can control the damping force of the rotating damper 6 by combining the working conditions of other equipment in the production line with the real-time monitoring data of the torque sensor, thereby realizing the control of the rotating roller 4 and realizing the automated production of the production line.

[0050] For example, when the feed rate of other equipment on the production line increases, the control center can send a corresponding torque reduction control command to the rotary damper 6 in a timely manner. The rotary damper 6 controls the damping force of the rotary damper 6 to decrease according to the torque reduction control command. This can reduce the rotational resistance of the rotating roller 4, thereby increasing the rotational speed of the rotating roller 4, and thus increasing the amount of felt conveyed.

[0051] For example, if a production line malfunctions and requires an emergency stop, the control center can promptly send a corresponding emergency stop control command to the rotary damper 6. Based on this command, the rotary damper 6 increases its damping force to its maximum value, maximizing the rotational resistance of the rotating roller 4 and causing it to brake and stop in time. This effectively stops the felt conveying mechanism. In this situation, it effectively prevents the felt conveying mechanism from continuing to output felt when the production line is paused, thus avoiding excessive felt output leading to stacking and blockage. This allows for coordinated control with other equipment on the production line, effectively improving production efficiency and safety.

[0052] Precise torque control can reduce excessive wear between the rotating roller 4 and other components, extending the service life of the equipment. Operators can flexibly adjust the damping force of the rotary damper 6 according to different working conditions such as the material and thickness of the felt and the conveying speed, improving the adaptability of the equipment.
