Description

Technical Field

[0001] This application relates to the field of foam material processing equipment, and in particular to a device for embossing the surface of pearl cotton. Background Technology

[0002] To improve the aesthetics of EPE foam, patterns with a design can be embossed on its surface. Existing embossing equipment mostly uses a liftable embossing plate and requires a feeding mechanism and a picking mechanism. However, because EPE foam has a low density, large area but light weight, air resistance has a significant impact during picking and placing operations, causing the sheet-like EPE foam to bend, making positioning and alignment difficult. Summary of the Invention

[0003] The purpose of this application is to provide a device for embossing pearl cotton surfaces that facilitates alignment and positioning.

[0004] To achieve the above objectives, this application provides a device for embossing the surface of pearl cotton: including a frame, on which a pair of tensioning wheels are rotatably connected, and a conveyor belt is driven between the two tensioning wheels. The frame is also provided with a drive mechanism and an embossing assembly. The drive mechanism includes a drive roller rotatably connected to the frame, located between the upper and lower inner surfaces of the conveyor belt, and adapted to drive the conveyor belt to move. The embossing assembly is located on the conveyor belt, and includes a synchronous roller rotatably connected to the frame, adapted to be driven by the drive roller. An embossing sleeve is provided over the synchronous roller. The outer surface of the conveyor belt is provided with a plurality of equally spaced barrier strips to prevent the pearl cotton from sliding on the outer surface of the conveyor belt.

[0005] As a preferred embodiment, the frame includes a base, on the upper surface of which a dual-shaft frame and a single-shaft frame are fixedly connected. The synchronous roller includes a support cylinder located between the dual-shaft frame and the single-shaft frame. The outer surface of the support cylinder has an internal toothed groove. The main body of the conveyor belt is a bottom support surface. Both sides of the bottom support surface have side rails. The inner side of the side rails has straight toothed grooves suitable for meshing with the internal toothed grooves. The outer side of the side rails protrudes from the outer side of the bottom support surface. The barrier strip is located between the two side rails and can form a rectangular positioning groove structure for constraining the pearl cotton on the surface of the conveyor belt.

[0006] As a preferred embodiment, the end of the support cylinder has a drive gear disc, and one end of the synchronous roller has a driven gear disc, which is adapted to mesh with the drive gear disc, so that the embossing assembly and the pearl cotton on the conveyor belt have the same linear speed, thereby avoiding embossing drag and misalignment.

[0007] As a preferred embodiment, the drive mechanism further includes an electric drive assembly located on the side of the dual-shaft frame. The electric drive assembly includes a motor and a reducer fixedly connected to the outer side of the dual-shaft frame. The drive gear is connected to the output end of the reducer via a linkage shaft to obtain rotational power.

[0008] As a preferred embodiment, the end face of the driven gear disc has a bridging shaft, the end of which passes through the dual-shaft frame and is fixedly connected to an anti-detachment disc to ensure the stability of the printing assembly on the frame.

[0009] As a preferred embodiment, the main body of the synchronous roller is a hollow cylinder, the outer surface of the hollow cylinder has guide strips, and the inner wall of the embossed sleeve is provided with guide grooves, which are suitable for interlocking with the guide strips to form a sliding pair, thereby suppressing the rotation of the embossed sleeve relative to the hollow cylinder and facilitating the replacement of the embossed sleeve.

[0010] As a preferred embodiment, a chuck is fixedly connected to the end of the hollow cylinder facing away from the driven gear plate via a connector. The end face of the hollow cylinder has an internal threaded hole, and the chuck has through holes with positions and numbers corresponding to the internal threaded holes. The connector passes through the through holes and engages with the internal threaded holes to ensure the chuck's restraining effect on the embossed sleeve.

[0011] As a preferred embodiment, two sets of wheel frames are also fixedly connected to the base. The tensioning wheel includes a follower roller, and the two ends of the follower roller have limiting rings. The conveyor belt is adapted to pass between the two limiting rings. The limiting rings cooperate with the wheel frame through the end shaft to form a rotating pair, which restricts the degree of freedom of the tensioning wheel, thereby maintaining stability.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By designing a conveyor belt structure with a positioning groove structure on the outer surface, the pearl cotton can adhere to the outer surface of the conveyor belt when it moves with the conveyor belt, which can effectively reduce the influence of air resistance and keep it flat. Combined with a cylindrical imprinting sleeve structure with the same linear speed, a uniform and regular imprinting pattern can be formed on the surface of the pearl cotton.

[0014] (2) By designing the embossing sleeve as a replaceable mating structure, the embossing device can form a variety of different types of patterns on the surface of pearl cotton, giving the embossing device more usage options. Attached Figure Description

[0028] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0030] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0031] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0032] like Figure 1-12 The pearl cotton surface embossing device shown includes a fixed frame 1, on which a pair of tensioning wheels 2 are rotatably connected. The two ends of the two tensioning wheels 2 are aligned and their axes are parallel. A conveyor belt 5 is driven between the two tensioning wheels 2 for conveying pearl cotton. Two sets of wheel frames 102 of equal height are also fixedly connected to the base 101. The specific structure of the tensioning wheel 2 includes a follower roller 203. The two ends of the follower roller 203 have coaxial limiting rings 202. The conveyor belt 5 passes between the two limiting rings 202 and wraps around the follower roller 203. The limiting rings 202 cooperate with the wheel frames 102 through the end shaft 201 to form a rotating pair. The end shaft 201 is also coaxial with the limiting rings 202.

[0033] The frame 1 is also equipped with a drive mechanism 3 and an imprinting assembly 4. The drive mechanism 3 includes a drive roller 320 rotatably connected to the frame 1. The drive roller 320 is located between the upper and lower inner surfaces of the conveyor belt 5 and is used to drive the conveyor belt 5 to move. The outer surface of the conveyor belt 5 is provided with a number of equally spaced barrier strips 504, all of which are parallel. The frame 1 includes a horizontal base 101. A double-shaft frame 103 and a single-shaft frame 104 are fixedly connected to the upper surface of the base 101. The synchronous roller 410 includes a support cylinder 323 located between the double-shaft frame 103 and the single-shaft frame 104. The axis of the support cylinder 323 is parallel to the axis of the follower roller 203. The outer surface of the support cylinder 323 is provided with an internal toothed groove 324. The main body of the conveyor belt 5 is the bottom. The bottom support surface 501 has side rails 502 on both sides. Both the bottom support surface 501 and the side rails 502 are made of flexible material, but the thickness of the side rails 502 is greater than that of the bottom support surface 501. The inner side of the side rails 502 protrudes from the inner surface of the bottom support surface 501. The inner side of the side rails 502 is provided with straight toothed grooves 503. The straight toothed grooves 503 are close to the end of the support cylinder 323 and mesh with the inner toothed grooves 324. The outer side of the side rails 502 also protrudes from the outer side of the bottom support surface 501. Therefore, the barrier strips 504 located on the outer surface of the bottom support surface 501 are all located between the two side rails 502. In this way, the outer surface of the conveyor belt 5 will form several evenly distributed rectangular placement slots for accommodating regularly shaped pearl cotton.

[0034] The printing assembly 4 is located above the conveyor belt 5. The specific structure of the printing assembly 4 includes a synchronous roller 410 rotatably connected to the frame 1, which can be driven to rotate synchronously by the drive roller 320. The end of the support cylinder 323 has a drive gear 322, and one end of the synchronous roller 410 has a driven gear 412, which meshes with the drive gear 322 to achieve linkage. The end face of the driven gear 412 has a coaxial bridging shaft 411. The end of the bridging shaft 411 passes through the double shaft frame 103 and is fixedly connected to an anti-detachment disc 415. The anti-detachment disc 415 can be fixedly connected to the bridging shaft 411 by bolts, which is convenient for disassembly and assembly and can prevent the bridging shaft 411 from detaching from the double shaft frame 103.

[0035] The drive mechanism 3 also includes an electric drive assembly 310 located on the side of the dual-shaft frame 103. The electric drive assembly 310 includes a motor 311 and a reducer 312 fixedly connected to the outer side of the dual-shaft frame 103. The output end of the motor 311 is connected to the input end of the reducer 312. The drive gear 322 is connected to the output end of the reducer 312 through the linkage shaft 321, thereby obtaining rotational power.

[0036] The synchronous roller 410 is covered with an embossed sleeve 420. The outer surface of the embossed sleeve 420 has raised textures, which can press corresponding patterns onto the surface of the pearl cotton. The main body of the synchronous roller 410 is a hollow cylinder 413. While ensuring sufficient structural strength, it is kept as lightweight as possible. The outer surface of the hollow cylinder 413 has guide strips 414, and there are several guide strips 414, all parallel to the axis of the hollow cylinder 413. The inner wall of the embossed sleeve 420 has guide grooves 421, which fit into the guide strips 414 to form a sliding pair. The hollow cylinder 413 has a back... A chuck 430 is fixedly connected to one end of the driven gear 412 via a connector 404. The outer diameter of the chuck 430 is larger than the inner diameter of the embossed sleeve 420, which can effectively prevent the embossed sleeve 420 from slipping off the hollow cylinder 413. In fact, in order to facilitate the disassembly and assembly of the chuck 430, an internal threaded hole 416 is provided on the end face of the hollow cylinder 413, and the chuck 430 is provided with through holes 431 whose position and number correspond to the internal threaded holes 416. The connector 404 is usually a bolt, which passes through the through hole 431 and engages with the internal threaded hole 416 to achieve tightening and fixation.

[0037] Working principle: During operation, the electric drive assembly 310 drives the conveyor belt 5 through the active roller 320. The flat rectangular pearl cotton falls into the rectangular frame formed on the outer surface of the conveyor belt 5 and moves forward with the conveyor belt 5. When the pearl cotton passes the synchronous roller 410 driven by the active roller 320, it will be pressed into a specific pattern by the raised texture on the outer surface of the embossing sleeve 420. Because the raised texture on the surface of the embossing sleeve 420 is very high, it will cause the pearl cotton to form an irreversible texture. After pressing, the pearl cotton will continue to move forward with the conveyor belt 5 to enter the next process. When it is necessary to change the texture of the pearl cotton surface, the chuck 430 can be removed, the embossing sleeve 420 with the corresponding texture can be replaced, and the chuck 430 can be reinstalled to restart the device to emboss the pearl cotton.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
