Description

Technical Field

[0001] This utility model relates to the field of foam production line equipment, and in particular to a foam storage device. Background Technology

[0002] Foam, also known as foam material or sponge, is a polymer material formed by dispersing a large number of gas micropores in a solid plastic. It is characterized by its porous, lightweight, and elastic properties, and is ubiquitous in our daily lives and industrial production.

[0003] A foam production line mainly consists of an output unit and a winding unit. The foam produced by the output unit is recycled by the winding unit, which winds the foam onto an empty roll. When the roll reaches its predetermined load capacity, a new roll needs to be replaced to continue winding.

[0004] There is often a mismatch between the winding speed and the output speed: if the winding speed is less than the output speed, the foam cannot be recycled in time, causing it to accumulate between the output device and the winding device, affecting the continuity and efficiency of the production process. Utility Model Content

[0005] To overcome the shortcomings of existing technologies where the winding speed and the output speed are often out of sync, resulting in foam not being able to be recycled in time if the winding speed is less than the output speed, causing it to accumulate between the production device and the winding device and affecting the continuity and efficiency of the production process, this utility model provides a foam storage device, including: a material rack; a drive assembly, which is equipped with multiple drive rollers and the same number of motors, with each drive roller and motor connected in a one-to-one correspondence, and the multiple drive rollers are spaced apart on the material rack, with a storage space inside the material rack below each adjacent drive roller.

[0006] Optionally, multiple drive rollers are mounted on the material rack in parallel and at equal intervals.

[0007] Optionally, a position sensor is installed inside the rack.

[0008] Optionally, the material rack is equipped with multiple partitions, which are located at the bottom of the drive roller.

[0009] Optionally, the top of the material rack is equipped with a support, on which multiple passive rollers are mounted, with the passive rollers located between two adjacent active rollers.

[0010] Optionally, the bracket is movably mounted on the material rack, and the material rack is equipped with a first cylinder, which is connected to the bracket.

[0011] Optionally, a feeding roller assembly is provided on one side of the material rack.

[0012] Optionally, the feeding roller assembly includes a first feeding roller and a second feeding roller. The first feeding roller is movably mounted on the material rack, and a second cylinder is provided on the material rack. The second cylinder is connected to the first feeding roller.

[0013] Optionally, the material rack is equipped with a feeding platform, and the feeding platform is equipped with feeding rollers.

[0014] Optionally, a thickness measurement module is provided on the unloading platform.

[0015] The beneficial effects of this utility model are: the active rollers are spaced apart, and the foam between two adjacent active rollers bends under the action of gravity. The bent part is located in the storage space. The foam placement method can make the foam retain a longer length on the material rack. The storage length of the foam on the material rack can be adjusted by adjusting the rotation speed of the active rollers. Regardless of how the winding speed of the winding device changes or how the output efficiency of the production equipment changes, the foam can maintain an appropriate storage amount on the material rack, avoiding the foam from piling up randomly, and achieving a good transition of foam between the production device and the winding device.

[0023] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, this utility model provides a foam 3 storage device, which is used as a transition device in the foam 3 production line. Specifically, it is installed between the production device and the winding device to store foam 3 and prevent foam 3 from accumulating between the production device and the winding device. Specifically, it includes: a material rack 1; a drive assembly, which is provided with multiple active rollers 201 and the same number of motors 202. The active rollers 201 and the motors 202 are connected one-to-one. The multiple active rollers 201 are spaced apart on the material rack 1. The space between two adjacent active rollers 201 corresponds to the storage space 101 inside the material rack 1.

[0025] The material rack 1 is a frame structure used to support other components; the drive assembly is used to drive the foam 3 to move on the material rack 1.

[0026] In implementation, multiple drive rollers 201 from the drive assembly are installed on the material rack 1, spaced apart. A motor 202 is installed on the material rack 1, and the drive rollers 201 are connected to the motor 202. The motor 202 drives the drive rollers 201. The foam 3 discharge device is installed between the output device and the winding device in the foam 3 production line. The foam 3 is pulled out from the output device and placed on the multiple drive rollers 201 on the material rack 1. Then, the foam 3 is wound onto the winding device. The foam 3 moves from the output device to the foam 3 storage device and then to the winding device. The motor 202 drives the drive rollers 201 to rotate. Foam 3 is moved to the winding device by the push of the drive roller 201. The drive rollers 201 are spaced apart, and the foam 3 between two adjacent drive rollers 201 bends under the action of gravity. The bent part is located in the material storage space 101. First, this arrangement of foam 3 allows the foam 3 to retain a longer length on the material rack 1. Second, the rotation speed of the drive roller 201 can be adjusted according to the lowest point of the bent part. For example, when the lowest point of the bent part of the foam 3 between two drive rollers 201 is below a predetermined height, this indicates that the winding speed of the winding device is decreasing, and the length of the foam 3 on the material rack 1 is about to be reduced. If the length exceeds the predetermined limit, the rotation speed of the active roller 201 near the winding device can be increased, while the rotation speed of the active roller 201 near the output device can be decreased or stopped. This causes the lowest point of the curved portion of the foam 3 to rise within the storage space 101, thus accelerating the movement of the foam 3 to the winding device and preventing the curved portion of the foam 3 from exceeding the storage limit of the storage space 101 and causing accumulation. Alternatively, when the lowest point of the curved portion of the foam 3 between the two active rollers 201 is higher than another predetermined height, this indicates that the winding speed of the winding device is increasing. As the speed increases, the length of foam 3 on the material rack 1 decreases. At this time, the rotation speed between the two active rollers 201 can be slowed down or the rotation of the two active rollers 201 can be stopped. That is, the speed at which foam 3 moves to the winding device is slowed down, so that the lowest point of the curved part of foam 3 is lowered. By adjusting the rotation speed of the active rollers 201, the storage length of foam 3 on the material rack 1 can be adjusted. This ensures that no matter how the winding speed of the winding device changes or how the output efficiency of the production equipment changes, foam 3 can maintain an appropriate storage amount on the material rack 1, avoiding messy accumulation of foam 3 and achieving a good transition of foam 3 between the production device and the winding device.

[0027] Furthermore, multiple active rollers 201 are installed parallel to each other and equidistantly on the material rack 1. Each active roller 201 remains parallel on the material rack 1. The foam 3 is spread flat on the active rollers 201. The portion of the foam 3 between every two active rollers 201 bends downward under the action of gravity. The bent portion of the foam 3 is located within the storage space 101.

[0028] Furthermore, a position sensor 102 is installed inside the material rack 1.

[0029] The position sensor 102 is used to sense the position of the foam 3 within the storage space 101, specifically to sense the position of the lowest point of the bend of the foam 3.

[0030] During implementation, a position sensor 102 is installed at a predetermined position in the material rack 1. The sensor is installed to detect the lowest point of the bent part of the foam to determine whether the material rack 1 contains foam 3 of a predetermined length. This determines whether it is necessary to change the conveying speed of the active roller 201 or stop the active roller 201 to control the walking speed of the foam on the material rack 1.

[0031] Specifically, the material rack 1 is provided with a first detection position 113 and a second detection position 114. A position sensor 102 is installed on the first detection position 113, and a position sensor 102 is also installed on the second detection position 114. The first detection position 113 is located near the drive roller 201, such as... Figure 1 , 2 The dotted line represents the position of foam 3 in one scenario. This scenario refers to a situation where the lowest point of the curved portion of foam 3 is higher than the first detection position 113 (the position sensor 102 at the first detection position 113 changes from detecting foam 3 to no longer detecting it). This indicates that the winding speed of foam 3 is too fast, requiring slowing down or pausing the rotation of the drive roller 201. The second detection position 114 is set at a position far from the drive roller 201. Figure 1 , 2 As shown, this represents the position of foam 3 in another situation. This situation means that if the lowest point of the curved part of foam 3 is lower than the second detection position 114 (the position sensor 102 on the second detection position 114 changes from not being able to detect foam 3 to being able to detect foam 3), it indicates that the winding speed of foam 3 is too fast, and the rotation of the active roller 201 needs to be accelerated.

[0032] In some embodiments, the material rack includes an incoming side and an outgoing side. The incoming side is connected to the production equipment, and the outgoing side is connected to the receiving roll equipment. The incoming side of the material rack is provided with a third detection position and a fourth detection position. Position sensors are respectively provided on the third detection position and the fourth detection position, and the third detection position is located above the fourth detection position.

[0033] In practice, similar to the first and second detection positions, when the fourth detection position detects foam, it indicates that the foam is moving too slowly on the receiving side and will soon accumulate or touch the ground under the influence of gravity. At this time, the speed of the active roller on the material rack can be increased to make the foam on the receiving side of the material rack move faster, thereby avoiding the foam touching the bottom. The third detection position can usually always detect foam. When the third detection position cannot detect foam, it means that no material has been loaded or the foam is moving too fast and the position of the foam is already higher than the third detection position. At this time, the speed of the active roller on the material rack can be slowed down to make the foam on the receiving side of the material rack move slower and avoid the foam being taut.

[0034] In some embodiments, the material rack includes an incoming side and an outgoing side. The incoming side is connected to the production equipment, and the outgoing side is connected to the receiving roll equipment. The incoming side of the material rack is provided with a fifth detection position and a sixth detection position. Position sensors are respectively provided on the fifth detection position and the sixth detection position, and the fifth detection position is located above the sixth detection position.

[0035] During implementation, when the sixth detection position detects foam, it indicates that the foam is exiting the material rack too quickly, causing it to accumulate or touch the ground on the exit side due to gravity. In this case, the rotation speed of the drive roller on the material rack can be reduced to slow down the movement of the foam on the receiving side of the material rack, thus preventing the foam from touching the bottom. The fifth detection position can usually always detect foam. If the fifth detection position cannot detect foam, it indicates that the foam is moving too slowly, the winding speed is greater than the speed at which the foam exits the material rack, and the position of the foam is already higher than the fifth detection position. In this case, the rotation speed of the drive roller on the material rack can be increased to slow down the movement of the foam on the receiving side of the material rack, preventing the foam from being taut.

[0036] Furthermore, the material rack 1 is a square frame with a hollow center. The active roller 201 is located on the top of the material rack 1. Two crossbeams are provided on both sides of the top of the material rack 1. The motor 202 is fixed on one side by a mounting base. A bearing seat is provided on the crossbeam on the other side. One end of the bearing active roller 201 is connected to the motor 202, and the other end of the active roller 201 is connected to the bearing seat, so that the active roller 201 is located between the two crossbeams.

[0037] In some embodiments, the material rack 1 is provided with multiple partitions 103, which are located at the bottom of the drive roller 201.

[0038] During implementation, the material rack 1 is equipped with multiple active rollers 201, and there is a material storage space 101 between every two active rollers 201. A partition net 103 is installed at the bottom of the active rollers 201, and the partition net 103 separates the material storage space 101 at the bottom of every two active rollers 201.

[0039] like Figure 2As shown, in some cases, the material rack 1 is equipped with five or more drive rollers 201, and there is a storage space 101 between every two drive rollers 201. The number of storage spaces 101 is three. The material rack 1 below the second drive roller 201 and the fourth drive roller 201 is equipped with a partition net 103, which divides the material rack 1 into three storage spaces 101. Each storage space 101 is equipped with a first detection position 113 and a second detection position 114. For example, the first storage space 101 is surrounded by the material rack 1 on one side and the partition net 103 on the other side. The material rack 1 is equipped with the first detection position 113 and the second detection position 114. The second storage space 101 is surrounded by partition nets 103 on both sides. The partition net 103 is equipped with the first detection position 113 and the second detection position 114.

[0040] In some embodiments, the top of the material rack 1 is provided with a support 104, and a plurality of passive rollers 105 are provided on the support 104, with the passive rollers 105 located between two adjacent active rollers 201.

[0041] During implementation, a support 104 is installed on the top of the material rack 1, and multiple passive rollers 105 are set on the support 104, with the passive rollers 105 located between two active rollers 201.

[0042] Furthermore, the support 104 is movably mounted on the material rack 1. The material rack 1 is equipped with a first cylinder 106, which is connected to the support 104. The first cylinder 106 is used to drive the support 104 to rise or fall. When feeding material onto the material rack 1, the first cylinder 106 first raises the support 104 so that the height of the passive roller 105 on the support 104 is greater than the height of the active roller 201. Then, the foam 3 is placed on the active roller 201. At this time, the first cylinder 106 drives the support 104 to fall, and the passive roller... The height of position 105 is lower than the height of the active roller 201. As mentioned earlier, foam 3 will form a curved part between the two active rollers 201. If the winding speed is fast, the curved part will be gradually straightened. The passive roller 105 is located between the two active rollers 201 and its height is lower than the height of the two active rollers 201. When foam 3 is gradually straightened, it will be resisted by the passive roller 105. Due to the material characteristics of foam 3, it is easy to deform it when it is taut for a long time, which can prevent foam 3 from being completely straightened.

[0043] The specific movable connection is achieved by having a mounting plate on the material rack 1, a guide rail on the mounting plate, and a bracket 104 mounted on the guide rail.

[0044] In some embodiments, a feeding roller assembly is provided on one side of the material rack 1.

[0045] Among them, the feeding roller group is used as the roller group through which foam 3 is fed.

[0046] During implementation, the foam 3 pulled out by the production device first passes through the feeding roller group and then onto the drive roller 201.

[0047] In some embodiments, the feeding roller assembly includes a first feeding roller 107 and a second feeding roller 108. The first feeding roller 107 is movably mounted on the material rack, and a second cylinder 109 is provided on the material rack 1. The second cylinder 109 is connected to the first feeding roller 107.

[0048] In practice, the first cylinder 106 can drive the first feeding roller 107 to bring the first feeding roller 107 closer to the second feeding roller 108, thereby changing the distance between the first feeding roller 107 and the second feeding roller 108 to accommodate foam 3 of different thicknesses.

[0049] In some embodiments, the material rack 1 is provided with a feeding platform 110, and the feeding platform 110 is provided with a feeding roller 111.

[0050] During implementation, foam 3 passes through the active roller 201, then through the feed roller 111 on the feed platform 110, and finally reaches the winding equipment.

[0051] like Figure 1 As shown, furthermore, a seventh detection position and an eighth detection position are provided on the material rack. The seventh and eighth detection positions are located between the drive roller and the feed roller, with the seventh detection position being higher than the eighth detection position. Position sensors are provided on the seventh and eighth detection positions respectively. The position sensors on the seventh and eighth detection positions are used to detect the distance between the foam and the material rack. The distance between the foam and the material rack can be preset. When the distance detected by the position sensor is lower than the preset distance, it indicates that the foam is too close to the material rack and the movement speed of the foam from the drive roller to the feed roller is too slow. The rotation speed of the drive roller can be increased to make the foam move faster.

[0052] In some cases, the foam on the feeding platform also undergoes labeling and drying processes.

[0053] In some embodiments, the unloading platform 110 is provided with a thickness measurement module 112.

[0054] During implementation, when foam 3 passes through the unloading platform 110, it will also pass through the thickness detection module 112, which is used to detect the thickness of foam 3.

[0055] Specifically, the thickness measurement module 112 includes a thickness sensor.

[0056] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
