Description

Technical Field

[0001] This utility model relates to the field of polishing device technology, specifically to a polishing device for the hard edges of automotive seat foam. Background Technology

[0002] To ensure the comfort of car seats, seat cushions and backrests are filled with seat foam. Since the foaming molds for seat foam are mostly open-top and closed structures, hard edges inevitably form around the perimeter during the foaming process. The presence of hard edges may increase the feeling of foreign objects on the surface of the car seat and affect the overall comfort.

[0003] Therefore, after the seat foam is foamed, its hard edges usually need to be sanded. In the existing technology, the sanding of the hard edges of seat foam is mostly done manually, that is, the operator holds a sanding machine to sand each one. This is not only difficult to operate and inefficient, but also very costly. Utility Model Content

[0004] In view of this, the present invention provides a grinding device for hard edges of car seat foam, which can speed up grinding efficiency and reduce labor intensity.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A device for sanding the hard edges of car seat foam, characterized in that: it includes a device base, on which a roller assembly and a sanding belt circumferentially sleeved are mounted, the sanding belt being at least partially exposed on the outside of the device base; the roller assembly includes a plurality of rollers rotatably mounted on the device base, and a drive assembly is provided on the device base for driving one of the rollers to rotate, thereby causing the sanding belt to rotate.

[0007] With the above structure, the drive component drives the roller to rotate, which in turn drives the sanding belt to rotate. The operator only needs to hold the seat foam and apply the hard edge to the moving sanding belt to achieve automated sanding, which greatly reduces the processing difficulty and improves the processing efficiency.

[0008] Preferably, the equipment base has a working platform on its upper side, and the rear end of the working platform has an upwardly extending mounting frame. Each of the rollers is rotatably mounted on the mounting frame in a vertical direction, and the abrasive belt is at least partially exposed on the front side of the mounting frame. With this structure, by placing the abrasive belt on the side wall, it is convenient for operators to use.

[0009] Preferably, the abrasive belt exposed on the outer side of the equipment substrate is elongated. This structure increases the usable area of ​​the abrasive belt, thereby effectively accelerating the abrasive grinding process.

[0010] Preferably, the top of the work platform has drainage holes. This structure facilitates the collection of foam debris generated during grinding.

[0011] Preferably, the lower end of the working platform is provided with a groove. This structure facilitates the collection of foam debris.

[0012] Preferably, the groove has a funnel structure, and a suction device is connected to the bottom of the groove. This structure enables automatic collection of foam debris, reducing the workload of operators.

[0013] Preferably, four rollers are provided: a first roller, a second roller, a third roller, and a fourth roller, arranged in a trapezoidal pattern. The drive assembly drives the first roller to rotate, and the abrasive belt between the third and fourth rollers is exposed on the outside of the equipment base. This trapezoidal arrangement allows for more stable rotation of the abrasive belt.

[0014] Preferably, a support plate is provided between the third and fourth rollers to support the abrasive belt. This structure provides support for the abrasive belt, ensuring its effectiveness.

[0015] Preferably, the drive assembly includes a drive motor disposed at the rear end of the device base and a rotating shaft fixedly connected to the output end of the drive motor, with one of the rollers rotatably mounted on the rotating shaft. This structure provides power for the rotational movement of the abrasive belt.

[0016] Preferably, both sides of the mounting frame have forward-extending baffles, and the two baffles and the mounting frame together form a foam-splash-proof area. This structure effectively prevents foam debris from splashing, thus ensuring a clean working environment.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The car seat foam hard edge grinding device provided by this utility model drives the roller to rotate through the drive component, which in turn drives the sanding belt to rotate. The operator only needs to hold the seat foam and apply the hard edge to the moving sanding belt to achieve automated grinding, which greatly reduces the processing difficulty and improves the processing efficiency.

[0019] 2. The suction device installed inside the working body can automatically collect the debris generated during the grinding process, saving operators the trouble of cleaning the equipment body and reducing their workload. Attached Figure Description

[0025] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0026] like Figure 1 and Figure 3 As shown, a device for sanding the hard edges of automotive seat foam includes a device base 1. A roller assembly and a sanding belt 2, which are rotatably mounted on the device base 1 and circumferentially sleeved around the roller assembly, are also included. The sanding belt 2 is at least partially exposed on the outside of the device base 1. The roller assembly includes four rollers rotatably mounted on the device base 1: a first roller 4, a second roller 5, a third roller 6, and a fourth roller 7. A drive assembly is also fixedly mounted on the device base 1 to drive one of the rollers to rotate, thereby causing the sanding belt 2 to rotate. In this embodiment, the drive assembly drives the first roller 4 to rotate.

[0027] With this design, the first roller 4 is driven to rotate by the drive component, which in turn drives the sanding belt 2 to rotate. The operator only needs to hold the seat foam and apply the hard edge to the moving sanding belt 2 to achieve automated sanding, which greatly simplifies the operation and increases the sanding efficiency.

[0028] like Figure 1 and Figure 3 As shown, a working platform 1a is provided on the upper side of the equipment base 1. A mounting frame 1b extending upward is formed at the rear end of the working platform 1a. The first roller 4, the second roller 5, the third roller 6 and the fourth roller 7 are all mounted on the mounting frame 1b in a vertical direction. The sanding belt 2 is at least partially exposed on the front side of the mounting frame 1b.

[0029] Specifically, such as Figure 3As shown, the first roller 4, the second roller 5, the third roller 6, and the fourth roller 7 are arranged in a trapezoidal shape on the mounting frame 1b. This design allows for more stable rotation of the abrasive belt 2. Specifically, the first roller 4 and the second roller 5 are respectively located at the left and right ends of the rear side of the mounting frame 1b, while the third roller 6 and the fourth roller 7 are located between the first roller 4 and the second roller 5, closer to the work platform 1a. Furthermore, the first roller 4 and the second roller 5 are of the same size, and the third roller 6 and the fourth roller 7 are of the same size, but their dimensions are smaller than those of the first roller 4 and the second roller 5. This design allows the third roller 6 and the fourth roller 7 to provide tension to the abrasive belt 2, thus making its rotation more stable.

[0030] In this embodiment, the abrasive belt 2 between the third roller 6 and the fourth roller 7 is exposed on the front side of the mounting bracket 1b, and the exposed abrasive belt 2 is generally elongated. This design can increase the contact area with the seat foam and further accelerate the abrasive efficiency.

[0031] like Figure 3 As shown, a support plate 8 is also fixedly installed between the third roller 6 and the fourth roller 7. The support plate 8 can support the sanding belt 2. When the operator presses the hard edge of the seat foam tightly against the sanding belt 2, the support plate 8 can prevent the sanding belt 2 from deforming under force, thereby ensuring the sanding effect of the sanding belt 2.

[0032] like Figure 4 As shown, the drive assembly includes a drive motor 9 fixedly installed at the rear end of the device base 1 and a rotating shaft 10 fixedly connected to the output end of the drive motor 9. In this embodiment, the first roller 4 is fixedly mounted on the upper end of the rotating shaft 10.

[0033] like Figure 4 and Figure 5 As shown in this embodiment, a protective cover 11 is also fixedly installed at the rear end of the equipment base 1. The protective cover 11 can cover the first roller 4 and the second roller 5. This design can protect the first roller 4 and the second roller 5 and also prevent the operator from accidentally touching them and causing personal injury.

[0034] In this embodiment, the roller assembly can be composed of four rollers, or it can be composed of two or three rollers.

[0035] like Figure 2As shown, a groove 1c is provided at the lower end of the work platform 1a, and an array of perforations 1a1 are formed on the top of the work platform 1a. When the hard edge of the seat foam is sanded by the sanding belt 2, foam debris will inevitably be generated. The foam debris can fall into the groove 1c from the perforations 1a1, which can save the operator from cleaning the surface of the work platform 1a later, thereby reducing the operator's workload.

[0036] In this embodiment, the groove 1a is set in the shape of a funnel, and a suction device 3 is fixedly installed at the bottom of the groove 1a. This design makes it easier to collect the generated foam debris. At this time, the set hole 1a1 can also filter out larger foam debris, so as to avoid larger foam debris affecting the normal use of the suction device 3.

[0037] like Figure 1 As shown, baffles 1d extend forward on both sides of the mounting frame 1b. The two baffles 1d and the mounting frame 1b can form a foam splash prevention area, thereby ensuring the cleanliness of the entire work area.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
