A feeding device for a sponge continuous foaming line and a method of using the same

Abstract

The present invention relates to the field of sponge foaming. The present invention discloses a feeding device for a sponge continuous foaming line and a method for using the same. The problem to be solved by the present invention is that when the sponge is foaming on a conveyor belt, paper needs to be attached to the surface of the conveyor belt so that the sponge foaming material is evenly spread on the surface of the paper. However, most existing equipment focuses on whether the upper surface is flat during the sponge foaming process, but ignores whether the lower surface is horizontal during the sponge foaming process. The existing sponge foaming material does not have a good contact effect with the edge of the paper, which results in the bottom edge being uneven after the sponge foaming is completed and there will be defects that affect the quality of the sponge. The present invention uses a leveling auxiliary device to make the bottom of the foaming material horizontal after foaming into a sponge, and will not cause the bottom to be uneven and defective due to the edge of the paper not contacting the foaming material.

Description

Technical Field

[0001] The invention relates to the field of sponge foaming, in particular to a feeding device for a sponge continuous foaming line and a use method thereof. Background Art

[0002] Current sponge production equipment is primarily categorized as discontinuous and continuous. Discontinuous sponge production equipment, due to mold size limitations, requires downtime for removal, resulting in high labor intensity and low production efficiency, making it unsuitable for mass production. Consequently, sponge production is typically performed on continuous foaming lines, where the material flowing from the feed pipe is evenly spread onto a sponge foaming conveyor belt. As the conveyor belt travels and reaction time increases, the material gradually grows into a sponge of a certain thickness.

[0003] In the existing sponge-connected production process, the foamed sponge is usually transported by a conveyor belt. When the sponge foams on the conveyor belt, paper needs to be attached to the surface of the conveyor belt so that the sponge foaming material is evenly spread on the surface of the paper. Most of the existing equipment focuses on whether the upper surface of the sponge is flat during the foaming process, but ignores whether the lower surface of the sponge is horizontal during the foaming process. The existing sponge foaming material does not have a good contact effect with the edge of the paper, which results in the bottom edge of the sponge being uneven after foaming and defects that affect the quality of the sponge.

[0009] Preferably, a fan is also provided on the support seat, and the fan is connected to the other end main shaft of the dual-axis motor. The fan is provided with an air outlet pipe, and the air outlet pipe is connected to the sleeve. The sleeve is hollow, and two groups of fan blades arranged opposite to each other are fixed on the sleeve. The sleeve is also provided with an air outlet hole, and the air outlet hole is located beside the two groups of fan blades.

[0010] Preferably, a branch pipe is further provided on the air outlet pipe, the branch pipe is communicated with the air outlet pipe, the branch pipe is fixedly arranged on the top of the support seat, and the air outlet end of the branch pipe is arranged toward the discharge pipe.

[0011] Preferably, a blocking member is also provided on the branch pipe, and the blocking member includes a support, a closing plate, a closing rod and a spring. The support is fixedly set on the branch pipe, and the closing plate is slidably set on the inner wall of the branch pipe. The closing rod is connected to the closing plate and slides with the support. A groove is provided in the support, and the two ends of the spring are respectively connected to the groove and the closing rod, and the discharge pipe is in contact with the closing rod.

[0012] Preferably, the method for using the feeding device of the sponge continuous foaming line comprises the following steps:

[0013] S1: When the sponge is foamed and fed, the foaming material in the feed box is transported to the discharge pipe through the feed pipe, and then the electric cylinder is driven to drive the mobile frame to move back and forth on the carrier frame. The two limit rods limit the mobile frame, and the reciprocating movement of the mobile frame drives the discharge pipe to move back and forth above the conveyor belt, so that the foaming material in the discharge pipe is evenly spread on the foam sponge paper on the conveyor belt, so that the foaming material can be effectively foamed into sponge and transported by the conveyor belt;

[0014] S2: When the foaming material in the discharge pipe is evenly spread on the paper of the conveyor belt, the dual-axis motor drives one of the rotating frames to rotate, and the rotation of one of the rotating frames drives the driving rod and the other rotating frame to rotate, and the driving rod is inclined, and then when the driving rod rotates, it drives the ball to make the card seat move in the deflection frame, and the tail end of the deflection frame is fixedly connected to the sleeve, and the two ends of the sleeve are limited by the support seat, and then when the card seat moves in the deflection frame, it drives the deflection frame to continuously deflect up and down, and the continuous up and down deflection of the deflection frame drives the two brackets to continuously vibrate the vibrating rods, and the two vibrating rods extend to the bottom of the foaming material paper of the conveyor belt, so that the foaming material in the discharge pipe can be quickly leveled when it moves to the conveyor belt by the vibration of the vibrating rod. This vibration method can quickly level the foaming material on the paper, thereby avoiding the inconsistent height of the upper surface of the foaming material during the foaming process on the conveyor belt, so that the subsequent operator needs to trim the sponge;

[0015] S3: When the dual-axis motor on the leveling auxiliary equipment rotates, the other end of the dual-axis motor will drive the fan to operate, and the fan will guide the inhaled air into the sleeve through the air outlet pipe, and the discharge pipe will move back and forth on the conveyor belt. During the movement, the discharge pipe will push the foaming material on the paper on the conveyor belt to the left and right sides to flatten it. The deflection frame will drive the sleeve to deflect forward and backward on the support seat. The relative fan blades on the sleeve will change the direction of the wind flowing out of the air outlet of the sleeve. When the discharge pipe drives the foaming material to move to the left, the deflection frame will be in an upward deflection, causing the sleeve to rotate clockwise. The clockwise rotation of the sleeve will drive one of the fan blades to blow the air from the air outlet in the sleeve to the left. At this time, the foaming material The material will be pushed by the discharge pipe and the direction of the wind and move obliquely to the left, effectively contacting the side edge of the paper on the conveyor belt. If the discharge pipe drives the foam material to move to the right side of the conveyor belt, the sleeve will rotate counterclockwise to make the other fan blade discharge air to the right. This setting can effectively make the foam material in the discharge pipe effectively contact the edge of the paper, so that the bottom of the foam material will be horizontal after it is foamed into a sponge, and will not be uneven or incomplete due to the edge of the paper not contacting the foam material. Most of the existing equipment only focuses on the horizontality of the top of the sponge, but does not pay attention to whether the bottom of the sponge can completely contact the edge of the paper. Therefore, this setting can effectively deal with the flatness of the bottom of the sponge.

[0016] S4: When the fan blades on the sleeve blow air, the card seat will slide on the deflection frame, and the sliding of the card seat will drive the guide plate to move above the conveyor belt. The guide plate is set at an angle to prevent the fan blades on the sleeve from blowing air outward, causing the foam material to move toward the discharge pipe. The guide plate can prevent the wind from moving in the direction of the discharge pipe and obstructing the wind, and will not affect the normal discharge operation of the discharge pipe;

[0017] S5: When the foaming operation is completed, the driving electric cylinder will drive the mobile frame to move toward the branch pipe. When the outer wall of the discharge pipe contacts the closing rod on the branch pipe, the closing rod will drive the closing plate to move in the branch pipe. At this time, the branch pipe will be ventilated to guide the wind in the outlet pipe to the bottom of the branch pipe. At this time, the wind will blow the bottom of the discharge pipe, thereby quickly cleaning the material on the discharge pipe.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] In the present invention, when the sponge is foamed and fed into the feed box, the foaming material in the feed box is transported to the discharge pipe through the feed pipe, and then the electric cylinder is driven to drive the movable frame to move back and forth on the carrier frame, and the two limit rods limit the movable frame. The reciprocating movement of the movable frame will drive the discharge pipe to move back and forth above the conveyor belt, thereby making the foaming material in the discharge pipe evenly spread on the foam sponge paper on the conveyor belt, so that the foaming material can be effectively foamed into sponge and transported by the conveyor belt.

[0020] When the carrier moves in the direction of rotation, the gear train of the driven gear is rotated to move upwards and downwards, and the gear train of the driven gear is rotated to move upwards and downwards, thereby the gear train of the driven gear is rotated and rotated, thereby the gear train of the driven gear is rotated and rotated, thereby the gear train of the driven gear is rotated and rotated, thereby the gear train of the driven gear is rotated and rotated, thereby the gear train of the driven gear is rotated and rotated, thereby the gear train of the driven gear is rotated and rotated,

[0021] In the present invention, when the dual-axis motor on the leveling auxiliary equipment rotates, the other end of the dual-axis motor will drive the fan to operate, and the fan will guide the inhaled air into the sleeve through the air outlet pipe, and the discharge pipe will move back and forth on the conveyor belt. During the movement, the discharge pipe will push the foaming material on the paper on the conveyor belt to the left and right sides to flatten it, and the deflection frame will drive the sleeve to deflect forward and backward on the support seat. The relative fan blades arranged on the sleeve will change the direction of the wind flowing out of the air outlet of the sleeve, and then when the discharge pipe drives the foaming material to move to the left, the deflection frame will be in an upward deflection, thereby causing the sleeve to rotate clockwise. The clockwise rotation of the sleeve will drive one of the fan blades to blow the wind from the air outlet in the sleeve to the left, and the foaming The material will move obliquely to the left under the push of the discharge pipe and the direction of the wind, and effectively contact the side edge of the paper on the conveyor belt. If the discharge pipe drives the foamed material to move to the right side of the conveyor belt, the sleeve will rotate counterclockwise to make the other fan blade discharge air to the right. This setting can effectively make the foamed material in the discharge pipe effectively contact the edge of the paper, so that the bottom of the foamed material will be horizontal after it is foamed into a sponge, and the bottom will not be uneven or incomplete due to the edge of the paper not contacting the foamed material. Most of the existing equipment only focuses on the horizontality of the top of the sponge, but does not pay attention to whether the bottom of the sponge can completely contact the edge of the paper. Therefore, this setting can effectively deal with the flatness of the bottom of the sponge.

[0022] Preferably, when the fan blades on the sleeve blow air, the holder will slide on the deflection frame, and when the holder slides, it will drive the guide plate to move above the conveyor belt. The guide plate is arranged at an angle to avoid the fan blades on the sleeve blowing air outward, causing the foaming material to move toward the discharge pipe. The guide plate can prevent the wind from moving in the direction of the discharge pipe and obstructing the wind, and will not affect the normal discharge operation of the discharge pipe.

[0023] Preferably, when the foaming operation is completed, the driving electric cylinder will drive the movable frame to move toward the branch pipe, and when the outer wall of the discharge pipe contacts the closing rod on the branch pipe, the closing rod will drive the closing plate to move in the branch pipe. At this time, the branch pipe will be ventilated to guide the wind in the outlet pipe to the bottom of the branch pipe. At this time, the wind will blow air to the bottom of the discharge pipe, thereby quickly cleaning the material on the discharge pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] When the sponge is foamed and fed into the feed box 22, the foaming material is transported to the discharge pipe 25 through the feed pipe 23, and then the electric cylinder 26 is driven to drive the movable frame 24 to move back and forth on the carrier frame 21. The two limit rods 27 limit the movable frame 24, and the reciprocating movement of the movable frame 24 will drive the discharge pipe 25 to move back and forth above the conveyor belt 11, so that the foaming material in the discharge pipe 25 is evenly spread on the foam sponge paper on the conveyor belt 11, so that the foaming material can be effectively foamed into sponge and transported by the conveyor belt 11.

[0036] In this embodiment, Figure 1 、 Figure 3 、 Figure 4 ,and Figure 5 As shown, a leveling auxiliary device 3 is provided beside the feeding device 2, and the leveling auxiliary device 3 includes a dual-axis motor 31, a support seat 32, a driving rod 33, a sphere 34, a clamping seat 35, a sleeve 36, a deflection frame 37 and two rotating frames 38. The support seat 32 is fixedly arranged on the conveying platform 1, and the support seat 32 is located on the top of the conveying platform 1. The dual-axis motor 31 is fixedly arranged on the outer wall of the support seat 32, and the two rotating frames 38 are symmetrically rotated on the support seat 32. One end of the main shaft of the dual-axis motor 31 is in transmission cooperation with one of the rotating frames 38. The two ends of the driving rod 33 are respectively connected to the two rotating frames 38, and the driving rod 33 is arranged at an angle. The ball 34 is arranged on the driving rod 33. The sleeve 36 is rotatably arranged on the support seat 32. One end of the deflection frame 37 is fixedly connected to the sleeve 36. The clamping seat 35 is slidably arranged on the deflection frame 37. The ball 34 is embedded in the clamping seat 35 and the ball 34 and the clamping seat 35 are rotatably cooperated.

[0037] Two brackets 39 extend outward from the bottom of the deflection frame 37. Both brackets 39 are provided with a vibration rod 391. The vibration rod 391 is inserted into the bottom of the foam material paper placed on the conveyor belt 11.

[0038] When the foaming material in the discharge pipe 25 is evenly spread on the paper of the conveyor belt 11, the dual-axis motor 31 will drive one of the rotating frames 38 to rotate, and the rotation of one of the rotating frames 38 will drive the driving rod 33 and the other rotating frame 38 to rotate, and the driving rod 33 is set at an angle, and then when the driving rod 33 rotates, it will drive the ball 34 to make the card seat 35 move in the deflection frame 37, and the tail end of the deflection frame 37 is fixedly connected to the sleeve 36, and the two ends of the sleeve 36 are limited by the support seat 32, and then when the card seat 35 moves in the deflection frame 37, it will drive the deflection frame 37 to move. The deflection frame 37 deflects up and down continuously, and the deflection frame 37 deflects up and down continuously, which drives the two brackets 39 to make the vibration rod 391 vibrate continuously. The two vibration rods 391 extend to the bottom of the foaming material paper of the conveyor belt 11, so that the foaming material in the discharge pipe 25 can be quickly leveled when it moves to the conveyor belt 11 by the shaking of the vibration rod 391. This vibration method can quickly level the foaming material on the paper, thereby avoiding the inconsistent height of the upper surface of the foaming material during the foaming process on the conveyor belt 11, so that the subsequent operator needs to trim the sponge.

[0039] In this embodiment, Figure 1 、 Figure 3 、 Figure 4 ,and Figure 5 As shown, a guide plate 392 is further provided at the bottom of the holder 35, and the guide plate 392 is arranged at an angle; when the fan blades 361 on the sleeve 36 blow air, the holder 35 will slide on the deflection frame 37, and when the holder 35 slides, it will drive the guide plate 392 to move above the conveyor belt 11. The guide plate 392 is arranged at an angle to avoid the fan blades 361 on the sleeve 36 from blowing air outward, causing the foaming material to move toward the discharge pipe 25. The guide plate 392 can prevent the wind from moving in the direction of the discharge pipe 25 and obstructing the wind, and will not affect the normal discharge operation of the discharge pipe 25.

[0040] In this embodiment, Figure 1 、 Figure 3 、 Figure 6 ,and Figure 7 As shown, the support base 32 is further provided with a fan 4, which is connected to the other end of the main shaft of the dual-axis motor 31. The fan 4 is provided with an air outlet pipe 41, which is connected to the sleeve 36. The sleeve 36 is hollow and fixed with two sets of fan blades 361 arranged opposite to each other. The sleeve 36 is also provided with an air outlet hole 362, which is located beside the two sets of fan blades 361.

[0041] When the dual-axis motor 31 on the leveling auxiliary equipment 3 rotates, the other end of the dual-axis motor 31 will drive the fan 4 to operate, and the fan 4 will guide the inhaled air through the air outlet pipe 41 to the sleeve 36, and the discharge pipe 25 will move back and forth on the conveyor belt 11. During the movement, the discharge pipe 25 pushes the foaming material on the paper on the conveyor belt 11 to the left and right sides to flatten it, and the deflection frame 37 will drive the sleeve 36 to deflect forward and backward on the support seat 32. The relative fan blades 361 provided on the sleeve 36 will change the direction of the wind flowing out of the air outlet 362 of the sleeve 36, and then when the discharge pipe 25 drives the foaming material to move to the left, the deflection frame 37 is in an upward deflection, thereby causing the sleeve 36 to rotate clockwise, and the clockwise rotation of the sleeve 36 will drive one of the fan blades 361 to move the air outlet hole 36 in the sleeve 36 The wind of 362 blows to the left, and at this time the foaming material will be pushed by the discharge pipe 25 and the direction of the wind and move obliquely to the left, and effectively contact the side edge of the paper on the conveyor belt 11. If the discharge pipe 25 drives the foaming material to move to the right side of the conveyor belt 11, the sleeve 36 will rotate counterclockwise to make the other fan blade 361 discharge air to the right. This setting can effectively make the foaming material in the discharge pipe 25 effectively contact the edge of the paper, and then make the bottom of the foaming material horizontal after it is foamed into sponge, and will not be uneven and incomplete due to the edge of the paper not contacting the foaming material. Most of the existing equipment only focuses on the horizontality of the top of the sponge, but does not pay attention to whether the bottom of the sponge can completely contact the edge of the paper. Therefore, this setting can effectively deal with the flatness of the bottom of the sponge.

[0042] In this embodiment, Figure 1 、 Figure 3 、 Figure 6 ,and Figure 7 As shown, the outlet pipe 41 is further provided with a branch pipe 42, the branch pipe 42 is connected to the outlet pipe 41, the branch pipe 42 is fixedly arranged on the top of the support base 32, and the outlet end of the branch pipe 42 is arranged toward the discharge pipe 25;

[0043] The branch pipe 42 is further provided with a blocking member 5, which includes a support 51, a closing plate 52, a closing rod 53 and a spring 54. The support 51 is fixedly provided on the branch pipe 42, and the closing plate 52 is slidably provided on the inner wall of the branch pipe 42. The closing rod 53 is connected to the closing plate 52 and slidably cooperates with the support 51. A groove is provided in the support 51, and the two ends of the spring 54 are respectively connected to the groove and the closing rod 53. The discharge pipe 25 is in contact with the closing rod 53.

[0044] When the foaming operation is completed, the driving electric cylinder 26 will drive the movable frame 24 to move toward the branch pipe 42. When the outer wall of the discharge pipe 25 contacts the closing rod 53 on the branch pipe 42, the closing rod 53 will drive the closing plate 52 to move in the branch pipe 42. At this time, the branch pipe 42 will be ventilated to guide the wind in the outlet pipe 41 to the bottom of the branch pipe 42. At this time, the wind will blow the bottom of the discharge pipe 25, thereby quickly cleaning the material on the discharge pipe 25.

[0045] The use method and advantages of the present invention: The use method of the feeding device of the sponge continuous foaming line has the following working process:

[0046] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 As shown:

[0047] S1: When the sponge is foamed and fed, the foaming material in the feed box 22 is transported to the discharge pipe 25 through the feed pipe 23, and then the electric cylinder 26 is driven to drive the mobile frame 24 to move back and forth on the carrier frame 21. The two limit rods 27 limit the mobile frame 24, and the reciprocating movement of the mobile frame 24 drives the discharge pipe 25 to move back and forth above the conveyor belt 11, so that the foaming material in the discharge pipe 25 is evenly spread on the foam sponge paper on the conveyor belt 11, so that the foaming material can be effectively foamed into sponge and transported by the conveyor belt 11;

[0048] S2: When the foaming material in the discharge pipe 25 is evenly spread on the paper of the conveyor belt 11, the dual-axis motor 31 will drive one of the rotating frames 38 to rotate, and the rotation of one of the rotating frames 38 will drive the driving rod 33 and the other rotating frame 38 to rotate, and the driving rod 33 is set at an angle, and then when the driving rod 33 rotates, it will drive the ball 34 to make the card seat 35 move in the deflection frame 37, and the tail end of the deflection frame 37 is fixedly connected to the sleeve 36, and the two ends of the sleeve 36 are limited by the support seat 32, and then when the card seat 35 moves in the deflection frame 37, it will drive the deflection frame 3 7 is constantly deflected up and down, and the deflection frame 37 is constantly deflected up and down, which drives the two brackets 39 to make the vibration rods 391 vibrate continuously. The two vibration rods 391 extend to the bottom of the foaming material paper of the conveyor belt 11, so that the foaming material in the discharge pipe 25 can be quickly leveled by the vibration of the vibration rods 391 when it moves to the conveyor belt 11. This vibration method can quickly level the foaming material on the paper, thereby avoiding the uneven height of the upper surface of the foaming material during the foaming process on the conveyor belt 11, so that the subsequent operator needs to trim the sponge;

[0049] S3: When the dual-axis motor 31 on the leveling auxiliary equipment 3 rotates, the other end of the dual-axis motor 31 will drive the fan 4 to operate, and the fan 4 will guide the inhaled air through the air outlet pipe 41 to the sleeve 36, and the discharge pipe 25 will move back and forth on the conveyor belt 11. During the movement, the discharge pipe 25 pushes the foaming material on the paper on the conveyor belt 11 to the left and right sides to flatten it, and the deflection frame 37 will drive the sleeve 36 to deflect forward and backward on the support seat 32. The relative fan blades 361 provided on the sleeve 36 will change the direction of the wind flowing out of the air outlet 362 of the sleeve 36, and then when the discharge pipe 25 drives the foaming material to move to the left, the deflection frame 37 is in an upward deflection, thereby causing the sleeve 36 to rotate clockwise, and the clockwise rotation of the sleeve 36 will drive one of the fan blades 361 to deflect the outlet of the sleeve 36 The wind from the air hole 362 blows to the left. At this time, the foaming material will be pushed by the discharge pipe 25 and the direction of the wind and move obliquely to the left, effectively contacting the side edge of the paper on the conveyor belt 11. If the discharge pipe 25 drives the foaming material to move to the right side of the conveyor belt 11, the sleeve 36 will rotate counterclockwise to make the other fan blade 361 discharge air to the right. This arrangement can effectively make the foaming material in the discharge pipe 25 effectively contact the edge of the paper, so that the bottom of the foaming material is horizontal after it is foamed into a sponge, and will not be uneven or defective due to the edge of the paper not contacting the foaming material. Most existing devices only focus on the horizontality of the top of the sponge, but do not pay attention to whether the bottom of the sponge can completely contact the edge of the paper. Therefore, this arrangement can effectively deal with the flatness of the sponge bottom.

[0050] S4: When the fan blades 361 on the sleeve 36 blow air, the holder 35 will slide on the deflection frame 37, and when the holder 35 slides, it will drive the guide plate 392 to move above the conveyor belt 11. The guide plate 392 is arranged at an angle to prevent the fan blades 361 on the sleeve 36 from blowing air outward, causing the foam material to move toward the discharge pipe 25. The guide plate 392 can prevent the wind from moving in the direction of the discharge pipe 25 and obstructing the wind, and will not affect the normal discharge operation of the discharge pipe 25.

[0051] S5: When the foaming operation is completed, the driving electric cylinder 26 will drive the movable frame 24 to move toward the branch pipe 42. When the outer wall of the discharge pipe 25 contacts the closing rod 53 on the branch pipe 42, the closing rod 53 will drive the closing plate 52 to move in the branch pipe 42. At this time, the branch pipe 42 will be ventilated to guide the wind in the outlet pipe 41 to the bottom of the branch pipe 42. At this time, the wind will blow the bottom of the discharge pipe 25, thereby quickly cleaning the material on the discharge pipe 25.

5. The method for using the feeding device of the sponge continuous foaming line according to claim 4, comprising the following steps: S1: When the sponge is foamed and fed, the foaming material in the feed box (22) is transported to the discharge pipe (25) through the feed pipe (23), and then the electric cylinder (26) is driven to drive the movable frame (24) to move back and forth on the carrier frame (21), and the two limit rods (27) limit the movable frame (24), and the reciprocating movement of the movable frame (24) drives the discharge pipe (25) to move back and forth above the conveyor belt (11), thereby making the foaming material in the discharge pipe (25) evenly spread on the foaming sponge paper on the conveyor belt (11), so that the foaming material can be effectively foamed into sponge and transported by the conveyor belt (11); S2: When the foaming material in the discharge pipe (25) is evenly spread on the paper of the conveyor belt (11), the dual-axis motor (31) drives one of the rotating frames (38) to rotate, and the rotation of one of the rotating frames (38) drives the driving rod (33) and the other rotating frame (38) to rotate, and the driving rod (33) is set at an angle, and when the driving rod (33) rotates, it drives the ball (34) to move the card seat (35) in the deflection frame (37), and the tail end of the deflection frame (37) is fixedly connected to the sleeve (36), and the two ends of the sleeve (36) are supported by the support seat (3 2) limiting, and then when the card seat (35) moves in the deflection frame (37), it will drive the deflection frame (37) to continuously deflect up and down, and the continuous up and down deflection of the deflection frame (37) will drive the two brackets (39) to make the vibration rod (391) continuously vibrate, and the two vibration rods (391) extend to the bottom of the foaming material paper of the conveyor belt (11), and then the foaming material in the discharge pipe (25) can be quickly leveled by the vibration of the vibration rod (391) when it moves to the conveyor belt (11). This vibration method can quickly level the foaming material on the paper; S3: When the double-axis motor (31) on the leveling auxiliary equipment (3) rotates, the other end of the double-axis motor (31) drives the fan (4) to operate, and the fan (4) guides the inhaled air through the air outlet pipe (41) to the sleeve (36), and the discharge pipe (25) moves back and forth on the conveyor belt (11). During the movement, the discharge pipe (25) pushes the foaming material on the paper on the conveyor belt (11) to the left and right sides to flatten it, and the deflection frame (37) drives the sleeve (36) to deflect forward and backward on the support seat (32). The relative fan blades (361) provided on the sleeve (36) change the direction of the air flowing out of the air outlet (362) of the sleeve (36). Then, when the discharge pipe (25) drives the foaming material to move to the left, the deflection frame (37) is in an upward deflection, and the foaming material moves to the left. The sleeve (36) rotates clockwise, and the clockwise rotation of the sleeve (36) drives one of the fan blades (361) to blow the wind from the air outlet (362) in the sleeve (36) to the left. At this time, the foaming material will be pushed by the discharge pipe (25) and the direction of the wind and move obliquely to the left, and effectively contact the side edge of the paper on the conveyor belt (11). When the discharge pipe (25) drives the foaming material to move to the right side of the conveyor belt (11), the sleeve (36) will rotate counterclockwise, causing the other fan blade (361) to discharge wind to the right. This setting can effectively make the foaming material in the discharge pipe (25) effectively contact the edge of the paper, so that the bottom of the foaming material is horizontal after it is foamed into a sponge, and the bottom will not be uneven or defective due to the edge of the paper not contacting the foaming material. S4: When the fan blades (361) on the sleeve (36) blow air, the holder (35) slides on the deflection frame (37), and when the holder (35) slides, it drives the guide plate (392) to move above the conveyor belt (11). The guide plate (392) is arranged to be inclined, thereby preventing the fan blades (361) on the sleeve (36) from blowing air outward, causing the foaming material to move in the direction of the discharge pipe (25). The guide plate (392) blocks the wind and prevents the wind from moving in the direction of the discharge pipe (25), which will not affect the normal discharge operation of the discharge pipe (25); S5: After the foaming operation is completed, the driving electric cylinder (26) drives the movable frame (24) to move toward the branch pipe (42). When the outer wall of the discharge pipe (25) contacts the closing rod (53) on the branch pipe (42), the closing rod (53) drives the closing plate (52) to move in the branch pipe (42). At this time, the branch pipe (42) is ventilated to guide the wind in the air outlet pipe (41) to the bottom of the branch pipe (42). At this time, the wind blows the bottom of the discharge pipe (25), thereby quickly cleaning the material on the discharge pipe (25).
