Description

Technical Field

[0001] This invention relates to the field of sponge processing, specifically to a sponge clamping and correction device. Background Technology

[0002] Currently, in foam mattress production lines, it's inevitable that the foam will shift position during transport. This necessitates a alignment device to correct the foam's position. Traditional alignment devices use alignment rollers on one or both sides of the conveyor belt. During alignment, the movement of these rollers pushes the foam along the conveyor belt, thus correcting its position. While this alignment structure works for ordinary foam, it's less effective for soft, thin foams, such as slow-rebound foam. In particular, the sides of the foam are prone to folding and wrinkling due to the movement of the alignment rollers.

[0003] Therefore, to address the aforementioned issues, patent CN216104545U proposes an air-float correction device for a foam mattress, comprising a correction bracket with a correction conveyor belt mounted on it, and air outlets on the conveyor belt; a blowing unit disposed within the conveyor belt, comprising a wind box with several air outlets at the upper end and several air inlets at the lower end, each air inlet connected to a blower; and a correction unit disposed above the conveyor belt, comprising a pair of correction plates disposed above the conveyor belt, the two correction plates being driven by a correction drive mechanism to move closer or further apart.

[0004] The aforementioned patent proposes using air blowing to correct the alignment of soft or thin sponges, preventing defects such as folding and wrinkling during the alignment process. However, in practical use, staff found that while air blowing is more effective than alignment rollers, it still requires an alignment plate to move the sponge after it is suspended in the air. This presents two risks: first, the sponge is suspended and, due to its softness or thinness, the alignment plate may be unable to move the sponge as a whole; second, the sides of the sponge may still fold or wrinkle due to the movement of the alignment plate. Therefore, the alignment device described in the patent is not very effective for correcting soft or thin sponges. Utility Model Content

[0005] The technical problem to be solved by the present invention is to provide a sponge-clamping and straightening device that can effectively correct the deviation of soft or thin sponges.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is: a cotton-skimming correction device, the innovation of which is: including

[0007] A correction bracket is provided, on which several conveying rollers are arranged along the conveying direction of the sponge, with gaps between adjacent conveying rollers.

[0008] The direction in which the sponge is transported is defined as the first direction, and the horizontal direction perpendicular to the first direction is defined as the second direction;

[0009] A sponge clamping mechanism is installed at the discharge end of the correction bracket. The sponge clamping mechanism includes a sponge clamping bracket, on which several clamping components distributed along a second direction are installed. The clamping of the sponge end is achieved through the cooperation of each clamping component.

[0010] An undulating unit is installed on the correction bracket. The undulating unit includes several lifting seats distributed along a first direction. Each lifting seat is respectively located at the gap of each conveying roller, and each lifting seat is driven by a lifting mechanism to switch back and forth between a first position and a second position. In the first position, the top height of the lifting seat is lower than the height of the conveying roller, and in the second position, the top height of the lifting seat is higher than the height of the conveying roller.

[0011] Furthermore, the clamping assembly includes a clamping plate, which includes a vertically arranged clamping plate body and a clamping base plate extending horizontally towards the correction bracket at the bottom of the clamping plate body. The clamping plate body is driven by a first lifting cylinder to switch back and forth between a third position and a fourth position. In the third position, the height of the clamping base plate is lower than the height of the conveying roller, and in the fourth position, the height of the clamping base plate is higher than the height of the conveying roller.

[0012] The clamping plate body is driven to move horizontally along a first direction by a horizontal mechanism mounted on the clamping bracket. The horizontal mechanism includes a transition plate, a horizontal screw, and a horizontal motor. The two sides of the horizontal screw are mounted on the clamping bracket and are driven to rotate by the horizontal motor. A screw nut is also provided on the horizontal screw for cooperation. The transition plate is mounted on the screw nut and moves horizontally along the horizontal screw under the drive of the screw nut. The clamping plate body and the first lifting cylinder are both mounted on the transition plate and move horizontally synchronously with the transition plate.

[0013] A clamping pressure plate is also provided above the clamping base plate. The clamping pressure plate is driven by a pressure cylinder installed on the clamping plate body to move up and down, thereby moving closer to or away from the clamping base plate.

[0014] Furthermore, a horizontally arranged guide rod is provided on each side of the clamping plate body on the clamping bracket, and guide through holes are opened on each side of the clamping plate body to allow the guide rod to pass through and move.

[0015] Furthermore, the lifting seat includes a lifting seat body, on which several sponge support columns are installed in sequence along the second direction. The sponge support columns are horizontally arranged, and the two sides of each sponge support column are movablely engaged with the lifting seat body through the cooperation of bearings.

[0016] The lifting mechanism includes a lifting bracket, on which each lifting seat is mounted. The lifting bracket is driven by a second lifting cylinder to move up and down, thereby driving all the lifting seats to move up and down synchronously, realizing the switching of the lifting seats between a first position and a second position.

[0017] Furthermore, a guide unit is provided between the lifting bracket and the correction bracket. The guide unit includes guide racks respectively arranged around the lifting bracket, and guide gears that mesh with each guide rack are also installed around the lifting bracket.

[0018] Furthermore, a sponge baffle is provided on each side of the correction bracket. The sponge baffle is located above the conveyor roller, extends along the first direction, and the two sponge baffles are driven by a translation mechanism to move closer or further away from each other along the second direction.

[0019] The translation mechanism includes a translation bracket mounted on a correction bracket. A pair of translation racks distributed and extending along a second direction are mounted on the translation bracket, and the two translation racks are staggered vertically. The two translation racks are respectively connected to two sponge baffles one-to-one through connecting plates. A translation gear is also mounted on the translation bracket, and the upper and lower sides of the translation gear mesh with the two translation racks respectively. The translation gear is driven to rotate by a translation motor mounted on the translation bracket, which drives the two translation racks to translate synchronously in opposite directions, thereby realizing the two sponge baffles moving closer or further apart.

[0020] Furthermore, the bottom end of the sponge baffle is also equipped with several cotton-blocking columns arranged sequentially along the first direction. The cotton-blocking columns are vertically arranged at the bottom end of the sponge baffle and are located above the conveying roller.

[0021] Furthermore, an auxiliary lifting unit is also provided on the correction bracket between the cotton clamping unit and the undulating unit. The auxiliary lifting unit includes a lifting bracket, which is connected to the undulating unit and moves up and down synchronously with the lifting seat. Several lifting plates distributed along the second direction are installed on the lifting bracket, and the lifting plates also switch back and forth between the first position and the second position with the lifting seat.

[0022] The advantages of this invention are as follows: The correction device of this invention, through the cooperation of the clamping mechanism and the undulating unit, realizes the clamping and up-and-down shaking of the sponge. In this way, it simulates artificial shaking, effectively avoiding adverse phenomena such as sponge folding, displacement, and wrinkling, and the correction effect is better.

[0023] The guide unit is designed with multiple guide racks and guide gears to provide excellent guidance for the vertical movement of the lifting bracket. Furthermore, by distributing the guide racks in different positions and cooperating with different guide gears, the vertical movement of the lifting bracket can be limited from multiple directions, resulting in a better guiding effect.

[0024] The auxiliary lifting unit is designed to provide auxiliary support for the sponge by setting up a lifting bracket and lifting plate that rise and fall synchronously with the lifting seat. This prevents the sponge from folding during the correction process due to its softness, which could occur when it is located between the clamping unit and the undulating unit, thus ensuring that the sponge can be smoothly corrected.

[0025] The fit between the guide rod and the guide through holes on both sides of the clamping plate body is to serve as a guide and limit when the transition plate moves horizontally, so as to prevent the transition plate from deviating and thus ensure the stability of the overall horizontal movement path of the clamping plate, and avoid deviations that would affect the subsequent clamping of the sponge.

[0026] By setting several foam-blocking columns at the bottom of the foam baffle, the height of the foam baffle can be increased, preventing the foam baffle from getting too close to the conveyor roller and affecting the smooth conveying of the foam by the conveyor roller.

[0034] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0035] like Figures 1-7 The illustrated device for correcting the alignment of cotton fibers includes:

[0036] A correction bracket 1 is a rectangular frame. Several conveying rollers 11 are arranged on the correction bracket 1 along the conveying direction of the sponge. The two sides of the conveying rollers 11 are movably mounted on the correction bracket 1 through the cooperation of bearings and bearing seats. There is a gap between two adjacent conveying rollers 11. The conveying rollers 11 are synchronized and rotate in the same direction through the cooperation of synchronous chains and synchronous sprockets. Any one of the conveying rollers 11 is driven to rotate by a motor mounted on the correction bracket 1, thereby driving all the conveying rollers 11 to rotate, so as to realize the conveying of the sponge.

[0037] The direction in which the sponge is transported is defined as the first direction, and the horizontal direction perpendicular to the first direction is defined as the second direction.

[0038] On both sides of the correction bracket 1, a sponge baffle 2 is respectively provided. The sponge baffle 2 is located above the conveyor roller 11 and extends along the first direction. At the bottom of the sponge baffle 2, several cotton-blocking columns 25 are installed in sequence along the first direction. The cotton-blocking columns 25 are vertically arranged at the bottom of the sponge baffle 2 and are located above the conveyor roller 11. By setting several cotton-blocking columns 25 at the bottom of the sponge baffle 2, the height of the sponge baffle 2 can be increased, preventing the sponge baffle 2 from being too close to the conveyor roller 11 and affecting the smooth conveying of the sponge by the conveyor roller 11. This effectively reduces the interference of the sponge conveying due to the presence of the sponge baffle 2, and at the same time facilitates the subsequent limiting of the sponge on both sides, providing a good foundation for the correction of the sponge.

[0039] The two sponge baffles 2 are driven by a translation mechanism to move horizontally along the second direction, thereby enabling the two sponge baffles 2 to move closer to or further away from each other.

[0040] The translation mechanism includes a translation bracket 21 mounted on a correction bracket 1. A pair of translation racks 22 are mounted on the translation bracket 21, which are distributed and extend along a second direction. The two translation racks 22 are staggered vertically. The two translation racks 22 are respectively connected to two sponge baffles 2 through connecting plates 2. Several connecting plates 2 are connected to the same sponge baffle 2. A translation gear 23 is also mounted on the translation bracket 21. The upper and lower sides of the translation gear 23 are respectively engaged with the two translation racks 22. The translation gear 23 is driven to rotate by a translation motor 24 mounted on the translation bracket 21, which drives the two translation racks 23 to move synchronously in opposite directions, thereby realizing the movement of the two sponge baffles 2 closer to or further away from each other.

[0041] Each connecting plate 23 connected to the same sponge baffle 2 is connected to a support bracket. A traveling rod is also provided on both sides of the upper end surface of the translation bracket 21 along the first direction, and the traveling rod extends along the second direction. A translation roller 26 supported on the traveling rod and reciprocating along the traveling rod is also installed at the bottom end of the support bracket. A translation guide rail is also provided on both sides of the upper end surface of the translation bracket 21 along the first direction. At the same time, a translation slider that cooperates with the translation guide rail is also installed at the bottom end of the support bracket.

[0042] When the sponge baffle 2 moves horizontally, the meshing between the translation gear 23 and the translation rack 22 provides the active power for the horizontal movement of the sponge baffle 2. The cooperation between the traveling rod and the translation roller 26 is used to ensure that the sponge baffle 2 can move horizontally smoothly. The cooperation between the translation guide rail and the translation slider is used to guide the horizontal movement of the sponge baffle 2 and prevent the sponge baffle 2 from deviating.

[0043] The clamping mechanism installed at the discharge end of the correction bracket 1, such as Figure 4 As shown in the schematic diagram, the sponge clamping mechanism includes a sponge clamping bracket 3, on which several clamping components distributed along the second direction are installed. The clamping components work together to clamp the end of the sponge.

[0044] like Figure 4 As shown in the schematic diagram, the clamping assembly includes a clamping plate 31, which includes a vertically arranged clamping plate body 311. At the bottom of the clamping plate body 311, there is a clamping base plate 312 extending horizontally towards the correction bracket 1. The clamping plate body 311 is driven by a first lifting cylinder 315 to switch back and forth between a third position and a fourth position. The first lifting cylinder 315 is a cylinder. In the third position, the height of the clamping base plate 312 is lower than the height of the top of the conveying roller 11. In the fourth position, the height of the clamping base plate 312 is higher than the height of the top of the conveying roller 11.

[0045] The clamping plate body 311 is driven to move horizontally along a first direction by a horizontal mechanism mounted on the sponge clamping bracket 3. The horizontal mechanism includes a transition plate 313, a horizontal lead screw, and a horizontal motor 314. The two sides of the horizontal lead screw are mounted on the sponge clamping bracket 3 through the cooperation of bearings and bearing seats, and the horizontal lead screw is driven to rotate by the horizontal motor 314. A lead screw nut is also provided on the horizontal lead screw for use with it. The transition plate 313 is mounted on the lead screw nut and moves horizontally along the horizontal lead screw under the drive of the lead screw nut. The clamping plate body 311 and the first lifting cylinder 315 are both set on the transition plate and move horizontally synchronously with the transition plate 313. The setting of the horizontal mechanism enables the horizontal movement of each clamping component in the first direction, so as to adjust the initial position of the clamping components according to different working conditions, so as to clamp different sponges.

[0046] On the clamping plate body 311, a horizontally arranged guide rod 318 is provided on both sides of the clamping plate body 311. Guide through holes are provided on both sides of the clamping plate body 311 to allow the guide rod 318 to pass through and move. The cooperation between the guide rod 318 and the guide through holes on both sides of the clamping plate body 311 serves to guide and limit the horizontal movement of the transition plate 313, preventing the transition plate 313 from deviating and ensuring the stability of the overall horizontal movement path of the clamping plate, thus avoiding deviations that could affect the subsequent clamping of the sponge.

[0047] A clamping pressure plate 316 is also provided above the clamping base plate 312. The clamping pressure plate 316 is driven by a pressure cylinder 317 installed on the clamping plate body 311 to move up and down, thereby moving closer to or away from the clamping base plate 312. The pressure cylinder 317 is a pneumatic cylinder.

[0048] An undulating unit is installed on the correction bracket 1. The undulating unit includes several lifting seats distributed along a first direction. Each lifting seat is respectively installed at the gap of each conveying roller 11. Each lifting seat is driven by a lifting mechanism to switch back and forth between a first position and a second position. In the first position, the top height of the lifting seat is lower than the top height of the conveying roller 11. In the second position, the top height of the lifting seat is higher than the top height of the conveying roller 11.

[0049] The lifting seat includes a lifting seat body 42, on which several sponge support columns 43 are installed in sequence along a second direction. The sponge support columns 43 are horizontally arranged, and the two sides of each sponge support column 43 are movablely engaged with the lifting seat body 42 through bearings, so that when the sponge is supported on the sponge support column 43, it can have a certain degree of mobility in the second direction for position adjustment and correction.

[0050] The lifting mechanism includes a lifting bracket 4, and the lifting seat body 42 of each lifting seat is installed on the lifting bracket 4. The lifting bracket 4 is a hollow cuboid bracket. The lifting bracket 4 is driven by the second lifting cylinder 41 to move up and down, thereby driving all the lifting seats to move up and down synchronously, realizing the switching of the lifting seats between the first position and the second position. The second lifting cylinder 41 is a cylinder and is located at the center of the lifting bracket 4.

[0051] A guide unit is also provided between the lifting bracket 4 and the correction bracket 1. The guide unit includes guide racks 44 arranged vertically around the lifting bracket 4. Guide gears 45 are also installed around the lifting bracket 4, each meshing with a corresponding guide rack 44. The guide gears 45 are movably mounted on the lifting bracket 4 through bearings. The design of the guide unit, using the cooperation of multiple guide racks 44 and guide gears 45, provides a good guiding effect for the vertical movement of the lifting bracket 4. Moreover, by distributing the guide racks 44 at different positions and cooperating with different guide gears 45, the vertical movement of the lifting bracket 4 can be limited from multiple directions, resulting in a better guiding effect. Furthermore, when the meshing guide gears 45 cooperate with the guide racks 44 for guidance, it is achieved by the rotation of the guide gears 45 on the guide racks 44. This does not interfere with the vertical movement of the lifting bracket 4, allowing the lifting bracket 4 to move up and down more smoothly.

[0052] An auxiliary support unit is also provided on the correction bracket 1 between the cotton clamping unit and the undulation unit, such as... Figure 7 As shown in the schematic diagram, the auxiliary lifting unit includes a lifting bracket 5. The two sides of the lifting bracket 5 are fixed to the lifting bracket 4 via connecting plates, thus rising and falling synchronously with the lifting seat. Several lifting plates 51, distributed along a second direction, are installed on the lifting bracket 5. These lifting plates 51 also switch back and forth between the first and second positions with the lifting seat. The lifting plates 51 are U-shaped channel steel. The design of the auxiliary lifting unit, through the cooperation of the lifting bracket 5 and the lifting plates 51 that rise and fall synchronously with the lifting seat, provides auxiliary lifting for the sponge. This prevents the sponge from folding during the correction process due to its softness, especially in the section between the clamping unit and the undulating unit, ensuring smooth correction of the sponge.

[0053] Working principle: When correcting the sponge, firstly, the sponge processed in the previous process is conveyed onto the conveyor roller 11. At this time, the lifting seat is in the first position, and the clamping plate 31 is in the third position. As the conveyor roller 11 conveys, the end of the sponge moves to the clamping unit position. At this time, the end of the sponge is above the clamping base plate 312. Then, the conveyor roller 11 stops conveying, and the clamping pressure plate 316 moves downward under the drive of the pressure cylinder 317, cooperating with the clamping base plate 312 to clamp the end of the sponge. Then, the translation motor 24 drives the translation gear 23 to rotate, and drives the two translation racks 23 to move synchronously in the opposite direction, thereby realizing the mutual approach of the two sponge baffles 2, and realizing the correction of the sponge. The two side ends are limited in the second direction, and the second lifting cylinder 41 drives the lifting bracket 4 to move up and down, thereby realizing the switching of each lifting seat between the first position and the second position. This method simulates the phenomenon of artificial shaking to correct the sponge. This correction method can effectively avoid defects such as sponge folding and wrinkling, and the correction effect is better. After the correction is completed, the lifting seat returns to the first position, and the clamping pressure plate 316 moves upward under the drive of the pressure cylinder 317 to release the end of the sponge. Then, the clamping plate 31 moves upward as a whole under the drive of the first lifting cylinder 315. At this time, the conveying roller 11 continues to work, conveying the sponge out of the correction bracket and into the next process.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
