Description

Technical Field

[0001] This utility model relates to the field of sponge processing technology, specifically to a sponge coating device and a sponge composite equipment. Background Technology

[0002] The main component of most sponges is polyurethane, and different manufacturing processes result in different products. Sponges can be laminated for packaging, heat-processed, and burst-opened according to customer requirements. Polyurethane sponges themselves have many air bubbles, but their air permeability is not very high. It is necessary to evenly coat sponge blocks of different types and densities with glue and then laminate them together.

[0003] In traditional glue application, the sponge is usually placed under the glue applicator manually and moved manually to be positioned. Then the glue applicator moves actively to spray the glue, and the sprayed sponge is removed manually before subsequent lamination operations are carried out. This process is time-consuming, labor-intensive, and has low production efficiency. Utility Model Content

[0032] In the description of this utility model, references to terms such as "one embodiment," "some alternative implementations," or "some optional embodiments," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0033] Please see Figures 1 to 2 One embodiment of this utility model provides a sponge coating device, including: a correction mechanism 10 and a coating mechanism 20.

[0034] The correction mechanism 10 is used to correct the position of the sponge relative to the feeding conveyor assembly 11. The correction mechanism 10 includes the feeding conveyor assembly 11, two correction plates 12 and a correction drive assembly 13. The two correction plates 12 are respectively arranged on both sides of the feeding conveyor assembly 11. The correction drive assembly 13 is driven to connect with the correction plates 12. The two correction plates 12 move closer to each other and further away from each other under the drive of the correction drive assembly 13.

[0035] The glue application mechanism 20 includes a sponge conveying assembly 21, a glue application lifting assembly 22, a glue application translation assembly 23, and multiple glue nozzles 24. The sponge conveying assembly 21 is located at the end of the feeding conveying assembly 11. The glue nozzles 24 are located above the sponge conveying assembly 21. The glue application lifting assembly 22 is driven to the glue nozzles 24. The glue nozzles 24 are lifted and lowered relative to the sponge conveying assembly 21 under the drive of the glue application lifting assembly 22. The glue application translation assembly 23 is driven to the glue nozzles 24. The glue nozzles 24 are moved relative to the sponge conveying assembly 21 in the glue application direction under the drive of the glue application translation assembly 23. The glue application direction is not parallel to the conveying direction of the sponge conveying assembly 21.

[0036] After the sponge is placed in the feeding conveyor assembly 11, the correction drive assembly 13 drives the two correction plates 12 to move closer together, so that the sponge is clamped and positioned by the two correction plates 12. Then, the correction drive assembly 13 drives the two correction plates 12 to move away from each other, and then the feeding conveyor assembly 11 can transport the sponge to the sponge conveying assembly 21. Of course, after the two correction plates 12 are clamped and positioned, the two correction plates 12 may not move away from each other or may only move slightly away from each other. During the process of the feeding conveyor assembly 11 transporting the sponge to the sponge conveying assembly 21, the correction plates 12 can guide the sponge, making the position of the sponge more accurate.

[0037] When at least a portion of the sponge reaches the sponge conveying assembly 21, the adhesive application lifting assembly 22 lowers the adhesive nozzle 24, bringing it closer to the sponge. Driven by the adhesive application translation assembly 23, the adhesive nozzle 24 moves in the adhesive application direction. Combined with the movement of the sponge driven by the sponge conveying assembly 21, the adhesive is sprayed along a suitable path. In this embodiment, the adhesive application direction is perpendicular to the conveying direction of the sponge conveying assembly 21. The adhesive nozzle 24 can spray adhesive back and forth onto the sponge in the adhesive application direction, while the sponge conveying assembly 21 gradually moves the sponge, achieving uniform adhesive application to the sponge.

[0038] By correcting the position of the sponge through the correction mechanism 10, the position of the glue nozzle 24 can be relatively accurate when the sponge is transported to the sponge transport assembly 21, so that the glue nozzle 24 can accurately spray the glue onto the sponge.

[0039] The correction drive assembly 13 can synchronously drive the two correction plates 12 to translate, or it can drive the two correction plates 12 to translate separately. Its specific structure can be selected according to actual needs. The correction drive assembly 13 can be a lead screw drive assembly, a rotary motor translation drive assembly, a belt translation drive assembly, a cylinder translation drive assembly, or a linear motor translation drive assembly, etc., and is not limited to this example. For example, the correction drive assembly 13 includes two correction electric cylinders, which are correspondingly driven and connected to the correction plates 12.

[0040] The way the adhesive application translation component 23 and the adhesive application lifting component 22 drive the colloid nozzle 24 can be selected according to actual needs. For example, the adhesive application translation component 23 is driven to move the adhesive application lifting component 22, thereby indirectly driving the colloid nozzle 24 to move. The adhesive application lifting component 22 directly drives the colloid nozzle 24 to move. In some optional embodiments, the adhesive application mechanism 20 also includes an adhesive application lifting frame 25, which is movably mounted above the sponge conveying component 21. The adhesive application lifting component 22 is driven to move the adhesive application lifting frame 25, and multiple colloid nozzles 24 are movably mounted on the adhesive application lifting frame 25, located respectively in front of and behind the adhesive application lifting frame 25 in the conveying direction of the sponge conveying component 21. The adhesive application lifting component 22 drives the adhesive application translation component 23 and the colloid nozzle 24 to move together by lifting the adhesive application lifting frame 25, thereby indirectly driving the colloid nozzle 24 to move. Increasing the number of colloid nozzles 24 can speed up the efficiency of applying colloid to the sponge. However, a large number of colloid nozzles 24 can lead to a narrow range of movement for the colloid nozzles 24, affecting the design requirements of the adhesive path. Moreover, adjacent colloid nozzles 24 need to maintain a distance from each other in the adhesive application direction to avoid collisions, which sometimes results in adhesive gaps on the sponge between adjacent colloid nozzles 24. Distributing the colloid nozzles 24 on the front and rear sides of the adhesive application lifting frame 25 can increase the number of colloid nozzles 24. At the same time, the colloid nozzles 24 located on the front side of the adhesive application lifting frame 25 and the colloid nozzles 24 located on the rear side of the adhesive application lifting frame 25 do not need to consider the spacing between them. This can avoid the situation where adjacent colloid nozzles 24 need to be spaced apart in the adhesive application direction, resulting in adhesive gaps on the sponge.

[0041] Please see Figure 3The structure of the adhesive application translation component 23 can be selected according to actual needs. For example, in some optional embodiments, the adhesive application translation component 23 includes multiple adhesive application translation seats 231, multiple adhesive application translation motors 232, and multiple translation transmission gears 233. The multiple adhesive application translation seats 231 are respectively movably arranged on the front and rear sides of the lifting frame. The adhesive application translation motors 232 are correspondingly arranged on the adhesive application translation seats 231 and are correspondingly driven and connected to the translation transmission gears 233. The colloid nozzles 24 are correspondingly installed on the adhesive application translation seats 231. The adhesive application lifting frame 25 is provided with translation transmission racks 234 on the front and rear sides of the sponge conveying component 21 in the conveying direction. The adhesive application translation seats 231 located on the same side of the adhesive application lifting frame 25 are arranged sequentially along the translation transmission racks 234. The translation transmission gears 233 mesh with the translation transmission racks 234. The translation transmission gear 233 on the glue-applying translation seat 231 located on the front side of the glue-applying lifting frame 25 meshes with the translation transmission rack 234 located on the front side of the glue-applying lifting frame 25, while the translation transmission gear 233 on the glue-applying translation seat 231 located on the rear side of the glue-applying lifting frame 25 meshes with the translation transmission rack 234 located on the rear side of the glue-applying lifting frame 25. The glue-applying translation motor 232 drives the translation transmission gear 233 to rotate, causing the translation transmission gear 233 to move relative to the translation transmission rack 234, thereby driving the glue-applying translation seat 231 to move along the translation transmission rack 234, thus driving the glue nozzle 24 located on the glue-applying translation seat 231 to move. Each glue-applying translation seat 231 can move independently, thereby individually driving each glue nozzle 24 to achieve a richer glue path. Moreover, the glue-applying translation seats 231 located on the same side of the glue-applying lifting frame 25 share the same translation transmission rack 234, which helps to simplify the structure. Furthermore, the precision of the movement of the colloid nozzle 24 can be improved by the cooperation of the translational transmission gear 233 and the translational transmission rack 234. In this embodiment, the front and rear sides of the glue application lifting frame 25 are also provided with support guide rails extending along the glue application direction, and the glue application translation seat 231 slides with the support guide rails, thereby improving the movement stability of the glue application translation seat 231.

[0042] Please see Figure 4In some optional embodiments, the adhesive application lifting assembly 22 includes an adhesive application fixing bracket 221, a lifting transmission rack 222, an adhesive application lifting motor 223, and a lifting transmission gear 224. The adhesive application fixing bracket 221 is disposed on the side of the sponge conveying assembly 21. The lifting transmission rack 222 is disposed on the adhesive application fixing bracket 221. The adhesive application lifting motor 223 is disposed on the lifting frame and is drivenly connected to the lifting transmission gear 224. The lifting transmission gear 224 meshes with the lifting transmission rack 222. The adhesive application lifting motor 223 drives the lifting transmission gear 224 to rotate, causing the lifting transmission gear 224 to move along the lifting transmission rack 222, thereby driving the adhesive application lifting frame 25 to rise and fall, thus achieving stable lifting and falling of the adhesive nozzle 24. The cooperation between the lifting transmission gear 224 and the lifting transmission rack 222 can improve the accuracy of the lifting and falling of the adhesive nozzle 24.

[0043] In some optional embodiments, the adhesive application lifting assembly 22 includes an intermediate drive shaft 225, two adhesive application fixing brackets 221, two lifting drive racks 222, and two lifting drive gears 224. The two adhesive application fixing brackets 221 are respectively disposed on both sides of the sponge conveying assembly 21, the adhesive application lifting frame 25 is located between the two adhesive application fixing brackets 221, the lifting drive racks 222 are correspondingly disposed on the adhesive application fixing brackets 221, the intermediate drive shaft 225 is rotatably mounted on the lifting frame and is located between the two adhesive application fixing brackets 221, and the two lifting drive gears 224 are assembled... The glue application lifting motor 223 is connected to the intermediate drive shaft 225 and meshes with two lifting drive racks 222. The glue application lifting frame 25 is supported by two glue application fixing brackets 221. The intermediate drive shaft 225 drives the two lifting drive gears 224 to rotate, which in turn drives the lifting drive gears 224 to rise and fall along the lifting drive racks 222. Since the power of the two lifting drive gears 224 is applied to the glue application lifting frame 25, the stability of the glue application lifting frame 25 is improved, and the wobbling of the glue application lifting frame 25 is avoided.

[0044] In some optional embodiments, the glue-applying fixing bracket 221 is provided with a plurality of lifting guide rails 226, and the glue-applying lifting frame 25 slides in cooperation with the lifting guide rails 226. The lifting guide rails 226 help to improve the lifting stability of the glue-applying lifting frame 25.

[0045] Please see Figures 5 to 6In some optional embodiments, the feeding and conveying assembly 11 includes a feeding bracket 111, a feeding drive module 112, multiple feeding conveying rollers 113, and multiple correction guide structures 114. The multiple feeding conveying rollers 113 are rotatably mounted on the feeding bracket 111 and arranged sequentially in the direction close to the sponge conveying assembly 21. The feeding drive module 112 is drivenly connected to the feeding conveying rollers 113. The correction guide structures 114 are disposed between adjacent feeding conveying rollers 113. The correction guide structures 114 include multiple guide wheels 1141, which are rotatably mounted on the feeding bracket 111 and arranged sequentially along the axial direction of the feeding conveying rollers 113. Under the drive of the correction drive assembly 13, the two correction plates 12 move closer to each other and further away from each other along the axial direction of the feeding conveying rollers 113. When the correction plates 12 move to drive the sponge to move, the sponge will drive the guide wheels 1141 to rotate. There is rolling friction between the sponge and the guide wheels 1141, which is beneficial for guiding the movement of the sponge and avoiding scratching. The feeding drive module 112 can be a feeding drive motor, which is connected to multiple feeding conveyor rollers 113 to drive the multiple feeding conveyor rollers 113 to rotate, but this example is not limited to this one.

[0046] Please see Figure 7 In some optional embodiments, the sponge coating device further includes a layered conveying mechanism 30, which includes a swing conveying component 31, a layered conveying support 32, and a swing drive component 33. The swing conveying component 31 is rotatably mounted on the layered conveying support 32. The beginning of the swing conveying component 31 is located at the end of the sponge conveying component 21. The swing conveying component 31 swings upward to a first position and downward to a second position under the drive of the swing drive component 33. When the swing drive component 33 is in the first position, the height of the end of the swing conveying component 31 is higher than the height of the end of the swing conveying component 31 when the swing drive component 33 is in the second position. The sponge is conveyed from the sponge conveying assembly 21 to the oscillating conveying assembly 31. The oscillating drive assembly 33 drives the oscillating conveying assembly 31 to oscillate up and down, allowing the sponge to detach from the oscillating drive assembly 33 at different heights. This allows the sponge to be conveyed to different height positions, facilitating subsequent sponge lamination. For example, after the first sponge is sprayed with glue, it is moved to the oscillating conveying assembly 31. At this time, the oscillating conveying assembly 31 is in the second position, and then the sponge is conveyed to the next process. The second sponge can be conveyed directly to the oscillating conveying assembly 31 without applying glue. At this time, the oscillating conveying assembly 31 is in the first position, so the second sponge can be conveyed to a higher height than the first sponge, facilitating the subsequent pressing of the second sponge onto the first sponge to achieve lamination.

[0047] The specific structures of the feeding conveyor assembly 11, the oscillating conveyor assembly 31, and the sponge conveyor assembly 21 can be selected according to actual needs, such as mesh belt conveyor assembly, roller conveyor assembly, chain conveyor assembly, and belt conveyor assembly. In this embodiment, the feeding conveyor assembly 11, the oscillating conveyor assembly 31, and the sponge conveyor assembly 21 all adopt belt conveyor assemblies.

[0048] The specific structure of the swing drive assembly 33 can be selected according to actual needs. For example, the swing drive assembly 33 can adopt several swing drive cylinders. The swing drive cylinders are set on the layered conveying bracket 32, and their output shafts are connected to the swing conveying assembly 31. This example is not limited to this one.

[0049] The starting point of the feeding conveyor assembly 11 refers to the position where the sponge enters the feeding conveyor assembly 11, and the ending point of the feeding conveyor assembly 11 refers to the position where the sponge leaves the feeding conveyor assembly 11; the starting point of the sponge conveyor assembly 21 refers to the position where the sponge enters the sponge conveyor assembly 21, and the ending point of the sponge conveyor assembly 21 refers to the position where the sponge leaves the sponge conveyor assembly 21; the starting point of the oscillating conveyor assembly 31 refers to the position where the sponge enters the oscillating conveyor assembly 31, and the ending point of the oscillating conveyor assembly 31 refers to the position where the sponge leaves the oscillating conveyor assembly 31.

[0050] In some optional embodiments, the layered conveying support 32 is provided with a plurality of buffer pads 34. When the swing conveying component 31 swings downward to the second position under the drive of the swing driving component 33, the swing conveying component 31 abuts against the buffer pads 34. The buffer pads 34 can provide a buffering function for the swing conveying component 31 to avoid damage to the swing conveying component 31 due to long-term collision.

[0051] The aforementioned sponge coating device can be applied to sponge composite equipment, which includes: the aforementioned sponge coating device.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
