Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and in particular to a pendulum cotton cloth forming mechanism for achieving uniform cotton cloth distribution and a method of using the mechanism. Background Art

[0002] In the field of rock wool production, the uniformity of the cotton distribution directly affects the quality stability of the final product. Traditional pendulum cotton laying machines mostly adopt fixed or simple reciprocating laying methods. However, traditional unformed cotton felt laying devices mostly adopt fixed or simple reciprocating laying methods, which are difficult to ensure the uniform distribution of unformed cotton felt on the conveyor belt. Due to the lack of flexibility, the fixed laying method cannot adjust the laying width and thickness according to actual production needs; and although the simple reciprocating laying method can achieve uniform laying of unformed cotton felt to a certain extent, the stroke amplitude and movement frequency of its reciprocating mechanism are difficult to achieve precise closed-loop control, which often leads to poor laying effects and even accumulation or gaps of unformed cotton felt.

[0003] Furthermore, this type of equipment generally suffers from the problem of insufficient stability in conveying unformed felt. Due to its stickiness and softness, unformed felt is prone to blockage or entanglement during conveyance, which not only affects laying efficiency but can also damage the equipment.

[0004] In response to the above problems, the present invention document proposes a pendulum cotton cloth forming mechanism for achieving uniform cotton cloth and a method of using the same. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the existing inability to adjust the pendulum swing amplitude in real time according to the thickness uniformity of the cotton cloth and the impact on the conveying speed of the unformed cotton felt, and to propose a pendulum cotton cloth forming mechanism for achieving uniform cotton cloth and its use method.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A pendulum cotton cloth forming mechanism for achieving uniform cotton cloth distribution, comprising: A U-shaped frame, wherein a frame body is provided through the U-shaped frame, and a conveyor belt conveyor is provided within the frame body; The pendulum is rotatably connected to the U-shaped frame through the base, and strip grooves are provided on both sides of the pendulum; The storage barrel is fixed to one side of the U-shaped frame and connected to the pendulum through a feed hose; The reciprocating swing structure includes two rotating disks, two base plates, a transmission rod and an adjustment structure; The base plate is fixed to the inner wall of the top of the U-shaped frame and is located on both sides of the rotating disk. The rotating disk is rotatably connected to the base plate through a rotating shaft. A pin is slidably provided on one side of the rotating disk deviating from the center of the circle, and the pin is slidably engaged with the strip groove. The adjustment structure includes a hydraulic cylinder, a piston rod, a box body, and an electric push rod. The hydraulic cylinder is connected to the box body through a fixed pipe. The piston rod is sealingly and slidingly connected to the hydraulic cylinder and fixed to the pin rod. The electric push rod controls the liquid level in the hydraulic cylinder through the piston plate to adjust the radial position of the pin rod. The vibration structure includes two round rods, a second synchronous wheel, an arc-shaped rack and a rotating wheel. The round rods are linked to the pendulum through the arc-shaped rack. The outer wall of the rotating wheel is provided with a hemispherical block to knock the feed hose.

[0007] In a possible design, the reciprocating swing structure further includes a transmission structure, which is composed of a first synchronous wheel and a first synchronous belt fixed to a transmission rod and a rotating shaft, and the transmission rod is driven by a motor.

[0008] In a possible design, the box of the adjustment structure is connected to the fixed pipe through a liquid guide pipe, and the liquid guide pipe and the fixed pipe are sealed with a flange.

[0009] In a possible design, the arc-shaped rack of the vibration structure is fixed to an arc-shaped plate, and the arc-shaped plate is slidably matched with the U-shaped frame and is fixed to both sides of the pendulum by bolts.

[0010] In a possible design, two meshing second gears are provided on one side of the pendulum, and the second gears drive the conveying wheels to rotate in opposite directions to convey the unformed cotton felt at a uniform speed.

[0011] In a possible design, a rotating ring is sleeved on the outer wall of the pin rod, and the rotating ring is in rolling engagement with the inner wall of the strip groove.

[0012] In one possible design, a U-shaped plate is fixed on the top of the frame, and multiple cylinders are arranged inside the U-shaped plate. A piston block is sealed and slidably connected inside the cylinder. The piston block drives the sliding rod and the rolling wheel to compact the cotton felt through the pressure of the inert gas.

[0013] In a possible design, a pressure sensor is embedded in the top end of the sliding rod, and the pressure sensor communicates with a control system to provide feedback on the compaction uniformity of the cotton felt.

[0014] In one possible design, the striking frequency of the hemispherical block is synchronized with the swing period of the pendulum.

[0015] In the present application, a method for using a pendulum cotton cloth forming mechanism to achieve uniform cotton cloth distribution includes the following steps: S1. Device startup and initial settings Start the motor to drive the transmission rod to rotate, and drive the rotating shaft and the rotating disk to rotate through the cooperation of the first synchronous belt and the first synchronous wheel; adjust the initial height of the piston plate of the electric push rod so that the distance between the pin rod and the center of the rotating disk meets the preset swing amplitude; transport the unformed cotton felt to the storage barrel through the pipeline, and enter the pendulum through the feed hose; synchronously start the drive device of the conveyor belt to ensure that the conveyor wheel rotates at a uniform speed.

[0016] S2. Pendulum swing and cotton felt conveying The rotating disk drives the pendulum to swing back and forth at a constant speed through the cooperation of the pin rod and the strip groove, and the cotton felt is evenly laid on the conveyor belt through the pendulum outlet; when the pendulum swings, the arc plate alternately engages with the first gear through the arc rack, and the driving round rod drives the rotating wheel to knock the feed hose to ensure that the cotton felt falls smoothly; the conveying wheel rotates synchronously through the engagement of the second gear, controlling the cotton felt conveying speed to match the pendulum swing frequency.

[0017] S3. Dynamic adjustment of swing amplitude According to actual laying requirements, the height of the piston plate is adjusted by the electric push rod, the volume of hydraulic oil in the hydraulic cylinder is changed, the piston rod is driven to drive the pin rod up and down, and the distance between the pin rod and the center of the rotating disk is adjusted; after the pin rod is displaced, the matching trajectory of the strip groove and the pin rod changes, realizing real-time control of the pendulum swing amplitude.

[0018] S4. Felt uniformity detection and feedback When the conveyor belt transports the laid cotton felt to the bottom of the U-shaped plate, multiple rolling wheels contact the surface of the cotton felt and move up and down as the thickness changes, compressing the inert gas in the cylinder; the sliding rod pushes the piston block upward, and the pressure sensor detects the pressure signals at different positions in real time; by comparing multiple sets of pressure data, if the uniformity does not meet the standard, the motor speed is adjusted to change the pendulum swing frequency, or the swing amplitude is adjusted by the electric push rod until the cotton felt is evenly distributed.

[0019] S5. Continuous operation and shutdown maintenance After completing the parameter calibration, keep the equipment running continuously and monitor the pressure sensor feedback data in real time; when shutting down, turn off the motor, conveyor belt and electric push rod in sequence, clean the remaining cotton felt in the storage barrel and pendulum, check whether the vibration function of the feed hose and rotating wheel is normal, and ensure the stability of subsequent operations.

[0020] Beneficial effect: In the present invention, the outer walls of the two round rods are fixedly sleeved with a first gear, the tops of the two arc-shaped plates are fixed with an arc-shaped rack, the outer walls of the two round rods are fixedly sleeved with a rotating wheel, and the outer walls of the two rotating wheels are fixed with a plurality of hemispherical blocks; the pendulum drives the arc-shaped plate to swing, and the cooperation of the arc-shaped rack and the first gear drives the two first gears and the round rod to rotate, and the round rod can continuously knock the feed hose through the hemispherical blocks on the outer wall of the rotating wheel to make it vibrate, thereby ensuring that the unformed cotton felt inside can smoothly enter the pendulum; In the present invention, a fixed tube is fixedly passed through each of the two base plates, and the ends of the two fixed tubes close to each other are rotated in sequence to pass through the rotating shaft and the rotating disk and are fixedly connected to the corresponding hydraulic cylinder. The bottom ends of the two liquid guide tubes are fixedly connected to one end of the two fixed tubes, and the bottom ends of the two piston rods are fixedly connected to the corresponding pin rods. The output shaft of the electric push rod drives the piston plate to rise and fall, and the box body is connected to the hydraulic cylinder through the liquid guide tube and the fixed tube, and then the pin rod can be driven to rise and fall through the piston rod. The change in the distance between the pin rod and the center of the circle can change the amplitude of the pendulum swing under the action of the strip groove. In the present invention, a plurality of cylinders are fixed to the top inner wall of the U-shaped plate, a piston block is sealingly and slidingly connected to the cylinder, a sliding rod is slidingly penetrated by the bottom inner wall of the cylinder, the bottom end of the sliding rod is rotatably connected to a rolling wheel via a rolling frame, and a pressure sensor is fixedly embedded on the top of the sliding rod; the inert gas in the cylinder drives the sliding rod and the rolling frame to move downward, which is used for preliminary compaction of the laid cotton felt, and the pressure sensor cooperates with the piston block to detect the pressure applied by the inert gas when compacting the cotton felt, and then the data of multiple pressure sensors are compared to detect the uniformity of the laying of the cotton felt, which is convenient for the later adjustment of the frequency and amplitude of the pendulum swing.

[0021] In the present invention, the uniformity of cotton felt laying can be detected in real time through the cooperation of the pressure sensor and the piston block, and the amplitude and frequency of the pendulum swing can be adjusted in time according to the uniformity to ensure that the pendulum can lay the unformed cotton felt evenly. In addition, the feed hose is continuously driven to vibrate when the pendulum swings to ensure that the unformed cotton felt in the feed hose smoothly enters the pendulum, avoiding the ununiform cotton felt laying in the later stage due to the blockage of the unformed cotton felt in the feed hose.

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Example 1: Reference Figure 1 The present invention relates to a forming mechanism, which relates to the technical field of cotton felt spreading equipment. The mechanism mainly includes a U-shaped frame 1, which serves as the basic supporting structure of the entire device. The U-shaped frame 1 is provided with a frame body 2, which runs through the U-shaped frame 1 and provides a stable support platform for a conveyor belt 3. The conveyor belt 3 is arranged in the frame body 2 and is used to transport the cotton felt after the cotton is spread.

[0026] Reference Figure 1-Figure 3A pendulum 4 is rotatably connected to the base within the U-shaped frame 1. This pendulum 4 is the core component for laying the felt. A storage barrel 38 is bolted to one side of the U-shaped frame 1. The top of the barrel 38 is connected to an external source of unformed felt via a delivery pipe, ensuring a continuous supply of unformed felt. A feed hose 39 connects the bottom of the barrel 38 to the pendulum 4, allowing the unformed felt to be smoothly transported to the pendulum 4 and evenly laid on the conveyor belt 3.

[0027] Reference Figure 2-Figure 5 In order to achieve the reciprocating swing of the pendulum 4 and ensure that the unformed cotton felt can be evenly laid on the conveyor belt 3, a reciprocating swing structure is set in the U-shaped frame 1. This structure includes two rotating disks 8 arranged on both sides of the pendulum 4 and two base plates 6 fixed to the top inner wall of the U-shaped frame 1, with the two base plates 6 located on both sides of the two rotating disks 8.

[0028] Reference Figure 2 、 Figure 4 、 Figure 5 and Figure 6 Specifically, the reciprocating swinging structure also includes a transmission rod 11 that rotates on the inner wall of one side of the U-shaped frame 1 through the base. The two base plates 6 are rotatably connected to the side close to each other with a rotating shaft 7. The two rotating shafts 7 are fixedly connected to one side of the corresponding rotating disk 8. The outer peripheral contour of the rotating disk 8 can adopt an involute type, an eccentric arc type or a compound cycloid type. When an eccentric arc is used in combination with an involute transition, the impact noise during high-speed operation can be effectively reduced. The two rotating shafts 7 are connected to the transmission rod 11 through a transmission structure, and the transmission structure consists of two first synchronous wheels 9 and a first synchronous belt 10. The two first synchronous wheels 9 are fixedly mounted on the transmission rod 11 and the outer wall of the rotating shaft 7, respectively, and the two first synchronous wheels 9 are connected by the first synchronous belt 10, thereby realizing the function of the transmission rod 11 driving the rotating shaft 7 to rotate. As the rotating disk 8 drives the pin 14 to rotate, the pin 14 cooperates with the strip groove 5 to drive the pendulum 4 to swing back and forth. The cross-sectional shape of the pin 14 can be circular, elliptical, or polygonal, with a hexagonal cross-sectional design providing torsion resistance. Pins 14 are slidably mounted on the sides of the two rotating disks 8 that approach each other, and the pins 14 are located off-center. Strip grooves 5 are provided on both sides of the pendulum 4, with the pins 14 slidingly engaging with the strip grooves 5. When the motor drives the transmission rod 11 to rotate, the transmission rod 11 drives the rotating shaft 7 and the rotating disk 8 through the first synchronous belt 10 and the two first synchronous wheels 9. The rotating disk 8, through the cooperation of the pin 14 off-center and the strip groove 5, drives the pendulum 4 to swing back and forth at a constant speed, thereby evenly laying the unformed cotton felt on the conveyor belt 3.

[0029] When the device is activated, unformed felt enters the storage barrel 38 from an external unformed felt storage source through a conveying pipe. Under the influence of gravity, the unformed felt enters the pendulum 4 through the feed hose 39. At this point, the motor drives the transmission rod 11, which, through the first synchronous belt 10 and the two first synchronous pulleys 9, drives the rotating shaft 7 and the rotating disk 8. The rotating disk 8, through the interaction of the pin 14, located off-center, and the strip groove 5, drives the pendulum 4 to swing back and forth at a constant speed, evenly distributing the unformed felt onto the conveyor belt 3.

[0030] Reference Figure 4 and Figure 7 In order to reduce the friction between the outer wall of the pin 14 and the inner wall of the strip groove 5 and increase the service life of the pin 14, a rotating ring 15 is rotatably sleeved on the outer wall of the pin 14, and the rotating ring 15 is located in the strip groove 5. In this way, when the pin 14 and the strip groove 5 cooperate to drive the pendulum 4 to swing, the rotating ring 15 can play a lubricating and buffering role, reducing wear and noise.

[0031] Reference Figure 3 and Figure 5-Figure 7 In addition, the reciprocating swing structure also includes an adjustment structure for adjusting the amplitude of the reciprocating swing of the pendulum 4 to meet different production needs. The adjustment structure includes two hydraulic cylinders 12 and a piston rod 13 that is sealed and slidably connected to the corresponding hydraulic cylinder 12. The structure also includes a box body 16 fixed on the top of the U-shaped frame 1, and both sides of the box body 16 are fixedly connected with a liquid guide tube 19. A fixed tube 20 is fixedly passed through the two base plates 6, and the ends of the two fixed tubes 20 that are close to each other are rotated in turn to pass through the rotating shaft 7 and the rotating disk 8 and are fixedly connected to the corresponding hydraulic cylinder 12. The bottom ends of the two liquid guide tubes 19 are fixedly connected to one end of the two fixed tubes 20, thereby connecting the hydraulic cylinder 12 with the box body 16.

[0032] Reference Figure 3 and Figure 7 A piston plate 18 is sealed and slidingly connected to the housing 16, and an electric push rod 17 is fixed to the top of the housing 16. The output shaft of the electric push rod 17 extends into the housing 16 and is fixedly connected to the top of the piston plate 18. It is used to control the raising and lowering of the piston rod 13 by controlling the raising and lowering of the piston plate 18. The bottom ends of the two piston rods 13 are fixedly connected to corresponding pins 14, which are used to control the position of the pins 14 from the center of the rotating disk 8, thereby adjusting the swing amplitude of the pendulum 4.

[0033] Specifically, when the swing amplitude of pendulum 4 needs to be adjusted, the output shaft of electric push rod 17 drives piston plate 18 up and down. The housing 16 is connected to the hydraulic cylinder 12 via a fluid conduit 19 and a fixed tube 20, which in turn drives pin 14 up and down via piston rod 13. As the distance between pin 14 and the center of the circle changes, the swing amplitude of pendulum 4 can be altered by the action of strip groove 5. This allows operators to flexibly adjust the swing amplitude of pendulum 4 according to actual production needs to achieve optimal felt laying results.

[0034] Reference Figure 3 、 Figure 8 and Figure 9 To drive the feed hose 39 to vibrate as the pendulum 4 reciprocates, allowing the unformed cotton felt inside to flow smoothly into the pendulum 4, a vibrating structure is also provided within the U-shaped frame 1. This structure comprises two rectangular holes 22 on either side of the U-shaped frame 1, each housing a rotating rod 23. A second synchronous pulley 26 is fixedly mounted on the outer wall of each rod 23. The two second synchronous pulleys 26 are connected by a second synchronous belt 27, which synchronizes the rotation of the two rods 23. A first gear 24 is fixedly mounted on the outer wall of each rod 23. Curved plates 21 are bolted to either side of the pendulum 4. The distal ends of the two curved plates 21 slide through the U-shaped frame 1. Curved racks 25 are fixed to the tops of each plate 21, meshing with the first gear 24. As the pendulum 4 swings, the coordination between the curved racks 25 and the first gear 24 drives the rods 23 to rotate. The outer walls of both round rods 23 are fixedly mounted with rotating wheels 28, one of which is located below the feed hose 39. Multiple hemispherical blocks 29 are fixed to the outer walls of both rotating wheels 28, which engage the feed hose 39. When the rotating wheels 28 rotate, the hemispherical blocks 29 strike the feed hose 39, allowing the unformed cotton felt in the feed hose 39 to smoothly enter the pendulum 4.

[0035] Specifically, when the pendulum 4 drives the curved plate 21 to swing, the curved plate 21 slides with the U-shaped frame 1, which can increase the stability of the pendulum 4's swing. In addition, the curved plate 21 can alternately drive the two first gears 24 to rotate when the pendulum 4 swings through the cooperation of the arc-shaped rack 25 and the first gear 24. The first gear 24 drives the round rod 23 to rotate, and the two round rods 23 are connected to the two second synchronous wheels 26 through the second synchronous belt 27. Therefore, when the pendulum 4 swings, the two round rods 23 can be driven to rotate back and forth synchronously. The round rod 23 can continuously knock the feed hose 39 through the hemispherical block 29 on the outer wall of the rotating wheel 28, causing it to vibrate, ensuring that the unformed cotton felt inside can smoothly enter the pendulum 4.

[0036] Reference Figure 4To transport the unformed felt in the pendulum 4 downward at a uniform speed, two conveyor wheels 40 are rotatably connected to the pendulum 4. The two conveyor wheels 40 are located near the opening at the bottom of the pendulum 4. One end of the output shaft of each conveyor wheel 40 extends to one side of the pendulum 4 and is secured to a second gear 37. The two second gears 37 mesh, allowing the two conveyor wheels 40 to rotate toward each other. This allows the unformed felt to enter the pendulum 4 and be transported downward at a uniform speed by the two conveyor wheels 40, ensuring uniform placement of the unformed felt on the conveyor belt 3.

[0037] During actual operation, the operator first adjusts the swing amplitude and frequency of pendulum 4 according to production requirements. The electric push rod 17 controls the raising and lowering of piston plate 18, which in turn adjusts the position of pin 14 relative to the center of rotating disk 8 to change the swing amplitude of pendulum 4. Simultaneously, the control system sets the motor speed and direction to control the swing frequency of pendulum 4.

[0038] Throughout the production process, operators can monitor and adjust the device's operating parameters in real time through the control system to ensure it is always in optimal working condition. At the same time, regular maintenance and servicing of the device is performed, including inspections of component wear and connection tightness, and timely replacement of damaged components to extend the device's service life and ensure safe and stable production.

[0039] Example 2: Reference Figure 1 and Figure 10 , an improvement based on Example 1: In order to preliminarily compact the cotton felt after laying, a U-shaped plate 30 is fixed to the top of the frame 2, and the U-shaped plate 30 is located on one side of the U-shaped frame 1. A plurality of cylinders 31 are fixed to the top inner wall of the U-shaped plate 30, and a piston block 32 is sealed and slidably connected inside the cylinder 31. Inert gas is stored between the top of the piston block 32 and the top inner wall of the cylinder 31, and a sliding rod 33 slides through the bottom inner wall of the cylinder 31. The top of the sliding rod 33 cooperates with the bottom of the piston block 32, and the inert gas above the piston block 32 is used to drive the sliding rod 33 to move downward.

[0040] refer to Figure 10 A rolling frame 35 is fixed to the bottom end of the sliding rod 33, and a rolling wheel 36 is rotatably connected to the rolling frame 35. When the inert gas in the cylinder 31 drives the sliding rod 33 and the rolling frame 35 downward, the rolling wheel 36 can perform preliminary compaction on the laid cotton felt. This allows for immediate preliminary compaction after the cotton felt is laid, improving its density and stability.

[0041] refer to Figure 10To detect the pressure applied by the inert gas during compaction of the felt, and to compare data from multiple pressure sensors 34 to check the uniformity of the felt placement and facilitate subsequent adjustment of the frequency and amplitude of the pendulum 4, a pressure sensor 34 is fixedly mounted on the top of the sliding rod 33. The pressure sensor 34, in conjunction with the piston block 32, monitors the pressure applied by the inert gas to the piston block 32 in real time and transmits the data to the control system for analysis and processing.

[0042] Specifically, after the felt is laid on the conveyor belt 3, the inert gas within the cylinder 31 drives the sliding rod 33 and the rolling frame 35 downward, and the rolling wheel 36 performs a preliminary compaction on the laid felt. At this time, the pressure sensor 34 monitors the pressure exerted by the inert gas on the piston block 32 in real time and transmits the data to the control system for analysis and processing. By comparing the data from multiple pressure sensors 34, the control system can detect the uniformity of the felt laying and adjust the frequency and amplitude of the pendulum 4's swing according to the actual situation to achieve the optimal laying effect.

[0043] A method for using a pendulum cotton cloth forming mechanism to achieve uniform cotton cloth distribution includes the following steps: S1. The unformed cotton felt is conveyed into the storage barrel 38 through the pipeline. The storage barrel 38 conveys the unformed cotton felt into the pendulum 4 through the feeding hose 39. The transmission rod 11 is driven by the motor to rotate. The transmission rod 11 drives the rotating shaft 7 and the rotating disk 8 to rotate through the first synchronous belt 10 and the two first synchronous wheels 9. The rotating disk 8 drives the pendulum 4 to swing back and forth at a constant speed through the cooperation of the pin rod 14 on the side deviating from the center of the circle and the strip groove 5, so that the cotton felt can be evenly laid on the conveyor belt conveyor 3. The frame 2 transports the laid cotton felt to the next process. S2, the pendulum 4 drives the arc plate 21 to swing, and the arc plate 21 and the U-shaped frame 1 slide together, which can increase the stability of the pendulum 4 swinging. In addition, the arc plate 21 cooperates with the first gear 24 through the arc rack 25. Therefore, when the pendulum 4 swings, the pendulum 4 alternately drives the two first gears 24 to rotate through the two arc racks 25. The first gear 24 drives the round rod 23 to rotate. The two round rods 23 are connected to the two second synchronous wheels 26 through the second synchronous belt 27, so the pendulum 4 swings. When the motor drives the two round rods 23 to rotate synchronously back and forth, the round rods 23 can continuously knock the feed hose 39 through the hemispherical block 29 on the outer wall of the rotating wheel 28 to make it vibrate, thereby ensuring that the unformed cotton felt inside can smoothly enter the pendulum 4, and the motor drives one of the conveying wheels 40 to rotate. The two conveying wheels 40 are meshed with each other through two second gears 37, and then the two conveying wheels 40 can uniformly convey the unformed cotton felt in the pendulum 4 downward, ensuring that the cotton felt can be evenly laid when the pendulum 4 swings; S3. When the swing amplitude of the pendulum 4 needs to be adjusted to achieve uniform paving, the output shaft of the electric push rod 17 drives the piston plate 18 to move up and down, and the box 16 is connected to the hydraulic cylinder 12 through the liquid guide tube 19 and the fixed tube 20. Then, the piston rod 13 can drive the pin 14 to move up and down. The change in the distance between the pin 14 and the center of the circle can change the swing amplitude of the pendulum 4 under the action of the strip groove 5; S4. When the conveyor belt conveyor 3 transports the laid cotton felt to the next process, the multiple rolling wheels 36 in the U-shaped plate 30 perform preliminary squeezing at different positions on the cotton felt, and during squeezing, the rolling wheels 36 move upward under the action of the cotton felt, compressing the inert gas in the cylinder 31 (which can be nitrogen or other harmless inert gases, not limited here), and when the sliding rod 33 pushes the piston block 32 to move upward, the pressure sensor 34 can detect the pressure applied by the sliding rod 33 to the piston block 32, and the pressure signals received by the pressure sensors 34 in the multiple cylinders 31 are compared, and the multiple rolling wheels 36 are at different positions, so that the uniformity of the laid cotton felt can be detected, which is convenient for the later adjustment of the rotation speed of the motor-driven transmission rod 11 and the pendulum 4, thereby adjusting the frequency of the pendulum 4 swinging, and the amplitude of the pendulum 4 swinging, so as to achieve the purpose of uniform laying of the cotton felt.

[0044] However, as those skilled in the art are familiar with, the working principles and wiring methods of the pressure sensor 34 and the electric push rod 17 are commonplace and are conventional means or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
