Description

Technical Field

[0001] This invention relates to the field of door and window accessory processing equipment technology, specifically a high-speed automatic wind-up machine for door and window sealing strips. Background Technology

[0002] Door and window sealing strips are key sealing components in door and window systems. After production and processing, they need to be neatly wound into neat rolls using a winding machine for subsequent packaging, transportation, and use. Specialized winding equipment for door and window sealing strips is mainly used to complete the continuous winding operation of the sealing strips, combined with manual straightening, combing, and correction of the strip positions to ensure the basic neatness of the rolled strips.

[0003] However, existing conventional door and window sealing strip winding equipment has a simple structure, relying solely on ordinary fixed-speed motors to drive the rollers. The speed adjustment range is limited, requiring staff to be on duty throughout the process. They rely on manual visual observation of the outer diameter of the roll to judge the fullness of the winding, resulting in low overall processing efficiency and failing to meet the needs of large-scale, high-efficiency strip production.

[0004] Therefore, it is necessary to design a high-speed automatic rewinding machine for door and window sealing strips that can reduce the workload of workers. Summary of the Invention

[0005] The purpose of this invention is to provide a high-speed automatic winder for door and window sealing strips to solve the problems mentioned in the background art.

The receiving mechanism is located above the frame 1, and the positioning mechanism, pneumatic shear, and winding frame are all located above the frame 2. A microcomputer control system and a winding motor are installed above the frame 3.

When the winding machine is winding, the dispensing mechanism 46 corresponds to the position of one set of sleeves, and the guide rail 12 corresponds to the position of another set of sleeves.

The sleeve is provided with a groove matching the protrusion 42 and the semi-circular blocks on the side near the rotating body 20 for limiting and preventing slippage during rotation.

[0028] The microcomputer control system 8 is connected to the winding motor 9, the feeding motor 15, the first cylinder 29, the cross linear module 32, the pneumatic finger 36, the rotary cylinder 39, the second cylinder 43, the dispensing mechanism 46, the third cylinder 48, and the switching motor via telecommunications, and is used to control the operation of each drive device.

[0029] The work process is as follows: Before starting the equipment, the operator feeds the entire roll of raw wool sliver into the inclined receiving frame 10 from the outside. The sliver passes through multiple sets of guide rollers 13 inside the receiving frame 10 and enters the parallel section of the L-shaped guide frame 11, where it is embedded in the limiting groove 17 of the adjusting wheel 16. The tension spring 27 pulls the swing frame 21 to bring the pressure roller 18 closer to the adjusting wheel 16, and then the pressure roller 29 clamps the sliver. The sliver moves upward into the vertical section of the guide frame 11, and two sets of cylinders 29 extend to drive the pressure roller 31 downward, which, together with the two sets of adjusting wheels 28, provides secondary guidance and limiting for the sliver (e.g., ...). Figure 12As shown), after the wool strip exits the guide frame 11, it first passes under a set of fixed rollers 55 on the support plate 4 54, wraps around the outer periphery of the floating roller 57, and then folds back through another set of fixed rollers 55 to complete the S-shaped tension winding. Subsequently, the wool strip is fed between the adjusting wheel 38 and the pressure roller 4 52. The rotary encoder 53 rotates synchronously with the adjusting wheel 38 to collect the feeding length pulse in real time. The wool strip finally enters the U-shaped guide rail 12 to achieve the discharge guidance. After the threading is completed, the operator presets parameters such as the target winding length, standard tension range, and speed of the feeding motor 15 and the winding motor 9 in the microcomputer control system 8, and the equipment is put into standby mode.

[0030] The dispensing mechanism 46 applies glue to the outer wall of the sleeve downwards at a fixed point. Then, the switching motor is started, causing the winding frame 7 to rotate 90 degrees around the output shaft axis, so that the glued sleeve faces the guide rail 12. The cross-linear module 32 is started, moving the bracket 34 and the guide rail 12 along the X and Y axes, so that the guide rail 12 corresponds to the glued sleeve, allowing the felt to adhere to the glue. The cylinder 48 is started, and the piston rod extends, moving the moving plate 50 and the winding motor 9 along the axis of the slide rail 49 until the rotating body 20 abuts against the sleeve. The protrusion 42 engages with the groove on the end face of the sleeve, forming a circumferential limit. The winding motor 9 is started, slowly rotating the sleeve clockwise. After one revolution, the operation stops, and cylinder 4 58 is started. The tension and pressure sensor pulls the floating roller 57 upward along the floating groove 56. The floating roller 57 presses against the S-shaped winding wool strip. The reaction force generated by the wool strip downward acts on the floating roller 57, and all the tension is transmitted to the tension and pressure sensor. The tension and pressure sensor transmits the real-time tension signal to the microcomputer control system 8. After the microcomputer control system 8 detects that the tension signal is normal, the feeding motor 15 starts, and the output shaft drives the adjusting wheel 16 to rotate and continuously traction the wool strip. The winding motor 9 is started to rotate synchronously. At the same time, the cross linear module 32 drives the bracket 2 34 and the guide rail 12 to move back and forth at a uniform speed along the X-axis, so that the wool strip is evenly spread on the outer circle of the sleeve.

[0031] Furthermore, throughout the feeding process, the tension sensor continuously collects real-time tension. If the measured tension exceeds the set upper limit, the output speed of the winding motor 9 is reduced to decrease the traction force; if the measured tension is less than the set lower limit, the speed of the winding motor 9 is slightly increased to increase the traction force. The feeding motor 15 synchronously follows the winding motor 9 to match the feeding speed, eliminating tension fluctuations caused by the difference in linear speed. The rotary encoder 53 at the end of the adjusting wheel 38 continuously accumulates pulses. Since the pneumatic shears 6 are located below the guide rail 12 but the rotary encoder 53 is located above the guide rail 12, there is a certain amount of invalid length between the rotary encoder 53 and the sleeve. The actual effective winding length of the sleeve = the total length detected by the rotary encoder 53 - the length of the guide rail 12. When the calculated effective length reaches the preset target length, the cutting step begins.

[0032] The cross-shaped linear module 32 is locked, stopping the horizontal material laying. The winding motor 9 and the feeding motor 15 decelerate and stop. The grippers of the pneumatic fingers 36 above the bracket 2 34 close and clamp the wool strip. The rotary cylinder 39 drives the rotating plate 40 to rotate, rotating the pneumatic scissors 6 to a position where its own axis is opposite to the wool strip. The piston rod of the cylinder 2 43 extends, moving the slider 1 and the pneumatic scissors 6 above along the slide rail 1 41, gradually approaching the wool strip. The pneumatic scissors 6 starts to cut the wool strip. After the cutting is completed, the cylinder 2 43 and the rotary cylinder 39 reset in sequence.

[0033] Cylinder 3 48 moves backward with winding motor 9 and rotating body 20, and protrusion 42 separates from the wound sleeve. Glue dispensing mechanism 46 dispenses glue to the outer wall of the empty sleeve. The switching motor inside bracket 44 starts, rotating winding frame 7 90° to rotate the new empty sleeve to the discharge position of guide rail 12. Cylinder 3 48 pushes winding motor 9 again to feed and engage with the empty sleeve. Microcomputer control system 8 resets the length count and starts counting the next roll, starting the next round of sliver winding cycle. The operator can remove the finished sleeve from below and replace it with an empty sleeve.

[0034] Example 2: This example is based on the structure and logic of Example 1, and analyzes the tension change of the felt strip during winding. As the cross-shaped linear module 32 drives the guide rail 12 to reciprocate left and right during the material laying process, the felt strip will undergo lateral bending and continuous changes in additional frictional resistance, which in turn causes drastic fluctuations in real-time tension, resulting in process defects such as uneven tightness of the sleeve roll, tensile deformation of the felt strip, and uneven winding end face.

[0035] Specifically, the microcomputer control system 8 is an integrated electronic control module, which integrates a tension acquisition unit, a lateral offset acquisition unit, and a roll diameter auxiliary calculation unit. The units work together to control the tension of the yarn. The core functions of each unit are as follows. Tension acquisition unit: Through the series connection of tension and pressure sensors between the piston rod of cylinder 4 58 and floating roller 57, the tension of the wool strip as it passes through the S-shaped tension detection section is acquired in real time, and transmitted to the microcomputer control system 8 via an electrical signal as the reference feedback value for tension closed-loop adjustment.

[0036] Lateral offset acquisition unit: It consists of the origin photoelectric sensor, servo motor and motor pulse feedback driver built into the cross linear module 32. The origin photoelectric sensor is used for automatic zeroing calibration for each roll cycle. The motor driver provides real-time feedback of forward and reverse motion pulses. The microcomputer control system 8 guides the track 12 to the real-time lateral offset through pulse conversion. At the same time, it identifies the uniform speed, acceleration and deceleration operation status of the module by relying on the pulse change rate.

[0037] Roll diameter auxiliary calculation unit: The speed encoder of the winding motor 9, together with the rotary encoder 53 at the end of the adjustment wheel 38, records the cumulative feeding length. The microcomputer control system 8 calculates the current outer diameter of the roll material in real time, which is used to superimpose roll diameter tension compensation.

[0038] Furthermore, after the equipment completes material feeding and debugging, the feeding motor 15 and the winding motor 9 are started. The cross-linear module 32 drives the guide rail 12 to reciprocate and move laterally to lay the material. The tension adaptive compensation synchronous continuous operation is carried out. The single-cycle adjustment steps are as follows: S1, multi-signal synchronous acquisition.

[0039] Specifically, the microcomputer control system 8 synchronously reads three sets of real-time data: the measured tension from the tension and compression sensors, the lateral offset from the motor pulse feedback driver of the cross-linear module 32, and the outer diameter of the current roll material calculated by the winding encoder.

[0040] S2, segment the lateral offset interval and calculate the static compensation tension.

[0041] Specifically, the microcomputer control system 8 uses the total material laying stroke as the dividing line, combines the real-time lateral offset collected by S1 to automatically divide the offset interval, and matches the corresponding static compensation tension.

[0042] Furthermore, the cross-shaped linear module 32 is evenly divided into eight segments according to its length. The central range is determined as follows: if the guide rail 12 is located within ±1 / 4 of the stroke center of the cross-shaped linear module 32, the lateral bending angle of the felt is extremely small, the lateral additional friction is negligible, and there is no compensation tension operation. The half-stroke offset range is determined as follows: if the guide rail 12 is offset from the center by 1 / 4 to 3 / 4 of the stroke, the felt produces a moderate lateral bending, the frictional resistance increases slightly, and a certain amount of compensation tension is added. The extreme offset range is determined as follows: if the guide rail 12 is offset from the center by more than 3 / 4 of the stroke and is close to the left and right material laying ends, the bending angle of the felt reaches its maximum value, the lateral frictional resistance is the maximum, and the compensation tension is increased.

[0043] S3, superimposed roll diameter compensation, generates real-time dynamic target tension.

[0044] Specifically, the operating conditions of the cross-shaped linear module 32 are distinguished according to the pulse change rate, and the static offset compensation tension obtained by S2 is corrected a second time.

[0045] Uniform material spreading state: The pulse change rate is constant, and the static compensation tension calculated in S2 is directly used; Acceleration / deceleration reversal state: The pulse rate continuously increases or decreases, and the instantaneous downward adjustment compensation parameter is superimposed on the static offset compensation tension to temporarily reduce the compensation tension and buffer the instantaneous tensile impact of reversal.

[0046] S4, closed-loop speed regulation, matches dynamic target tension.

[0047] Specifically, the dynamic tension is calculated in real time according to the formula: Dynamic target tension = Basic reference tension + Corrected static offset compensation tension + Roll diameter compensation tension. The microcomputer control system 8 compares the difference between the measured tension collected by the tension and compression sensors and the dynamic target tension calculated in real time, and synchronously adjusts the output speed and output torque of the winding motor 9, while the feeding motor 15 follows and matches the feeding speed.

[0048] When the measured tension is greater than the dynamic target tension, the speed of the take-up motor 9 is slightly reduced to decrease the traction force of the sleeve and prevent excessive stretching and deformation of the felt. When the measured tension is less than the dynamic target tension, the speed of the take-up motor 9 is slightly increased to increase the traction force and prevent the felt from becoming loosely wound and the end face of the roll from becoming uneven. When the difference between the measured tension and the dynamic target tension is within the preset allowable error range, the take-up motor 9 maintains its current speed for stable operation. All values ​​are monitored throughout the process to maintain appropriate tension in the felt, ensuring that the wound felt is evenly wound.
