Description

Technical Field

[0001] This utility model relates to the field of diaper changing table manufacturing technology, and more specifically, it relates to a vacuum adsorption bonding device for processing plastic parts. Background Technology

[0002] In the automated production of diaper changing tables, the bonding of the plastic base film with non-woven fabric and the changing table itself is a key process. In existing technologies, this process typically employs a vacuum adsorption device combined with hot melt adhesive spraying or ultrasonic welding to fix the multiple layers of material. However, traditional vacuum adsorption devices have the following technical drawbacks.

[0003] Currently, most existing vacuum adsorption platforms on the market adopt a fixed slot layout, and the adsorption force distribution relies solely on the constant pressure of the vacuum pump. When the plastic base film is being transported, due to the insufficient rigidity of the base film itself, local vacuum leaks are easily formed at the edge area of ​​the adsorption surface. This leakage will cause the base film to deviate periodically by 0.5 to 2 mm, which in turn will cause the hot melt adhesive coating trajectory to misalign with the nonwoven fiber layer.

[0004] When the nonwoven fiber layer is misaligned, it will cause the smoothed nonwoven fiber layer to shift in position during the molding process, which in turn causes the technical problem of wrinkles in the diaper table product after molding. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a vacuum adsorption bonding device for processing plastic parts that can prevent the nonwoven fiber layer from shifting.

[0007] By adopting the above technical solution, the technical problem of product wrinkling caused by the lack of a nonwoven fiber layer locking device in the bonding process of diaper changing table is solved. This results in the smoothed nonwoven fiber layer shifting in position during the mold closing process. The technical effect of improving the bonding quality of nonwoven changing table and reducing the product defect rate is achieved.

[0013] The present invention is further configured such that: the mold closing mechanism includes a limiting part and a telescopic cylinder; the limiting part is disposed on the side of the connecting part and is located on the outside of the machine housing; the telescopic cylinder is rotatably disposed on the side of the machine housing and the output end of the telescopic cylinder is rotatably connected to the limiting part.

[0014] By adopting the above technical solution, when the telescopic cylinder is started, it can drive the rotating connection limiting part and the connecting part connected to the limiting part to rotate, thereby realizing the upward and downward driving of the second sliding mold.

[0015] In summary, this application includes at least the following beneficial technical effects: By setting up an abutting mechanism, the technical problem in the existing technology of diaper table bonding process that the lack of a non-woven fiber layer locking device causes the smoothed non-woven fiber layer to shift in position during the mold closing process, thus causing product wrinkles, is solved.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0020] Please see Figure 1-8 The present invention provides the following technical solution: Example 1 includes a housing 1 and a controller 2 disposed beside the housing 1. The vacuum adsorption bonding device also includes an abutment mechanism 3 and a mold closing mechanism 4. The abutment mechanism 3 is disposed on the top of the housing 1 and includes a mold closing part 31, a flipping part 32 and an abutment part 33. The mold closing part 31 is disposed on the top of the housing 1 and has a cuboid structure. The mold closing part 31 is used to receive the workpiece 5 to be processed. There are multiple flipping parts 32, which are rotatably disposed on the top of the housing 1 and are all located beside the mold closing part 31. There are multiple abutment parts 33, which are disposed at the bottom of the multiple flipping parts 32 and are all circular structures. The mold closing mechanism 4 is disposed beside the housing 1.

[0021] To address the problem of wrinkles caused by nonwoven fabric fiber layer misalignment during the bonding process of diaper changing tables in existing technologies, the operator first places the nonwoven fabric fiber layer to be molded on top of the mold-closing part 31, which has a rectangular opening for placing the nonwoven fabric fiber layer. The operator then smooths the surface of the nonwoven fabric fiber layer. However, existing technologies lack a locking mechanism for the smoothed nonwoven fabric fiber layer. This deficiency means that in subsequent mold-closing processes, the smoothed nonwoven fabric fiber layer may still wrinkle due to positional misalignment, thus affecting the bonding quality of the diaper changing table. When the nonwoven fabric fiber layer is placed on top of the mold-closing part 31, the operator controls the flipping part 32 to flip. When the flipping part 32 flips, it drives the abutment part 33 to abut the smoothed nonwoven fabric fiber layer against the top of the machine housing 1, thereby preventing the smoothed nonwoven fabric fiber layer from misaligning during subsequent mold-closing processes and causing wrinkles in the molded product.

[0022] See Figure 5 and Figure 6 The abutting mechanism 3 also includes a positioning plate 34 and a hinge part 35; the positioning plate 34 has multiple parts and is respectively disposed on the top of the housing 1, and multiple flipping parts 32 are rotatably connected to the positioning plate 34; the hinge part 35 has multiple parts and is respectively rotatably disposed on the top of the flipping part 32, and when the hinge part 35 flips and abuts the positioning plate 34, it can drive the flipping part 32 to flip.

[0023] Specifically, when the nonwoven fiber layer is placed on top of the mold closing part 31, the worker rotates the hinge part 35. When the hinge part 35 rotates, it can drive the abutment part 33 to tilt along the rotatingly mounted positioning plate 34 until the abutment part 33 abuts against the smoothed nonwoven fiber layer.

[0024] See Figure 6The abutment mechanism 3 also includes a rotating part 36 and a rubber part 37; the rotating part 36 has multiple parts and is rotatably disposed on the top of the positioning plate 34; the rubber part 37 is disposed at the bottom of the rotating part 36, and can drive the rubber part 37 to rotate synchronously when the rotating part 36 rotates.

[0025] Specifically, in order to further fix the nonwoven fiber layer after it is abutted, after the nonwoven fiber layer is abutted by the abutting part 33, the worker rotates the rotating part 36. When the rotating part 36 rotates, the rubber part 37 can be abutted with the nonwoven fiber layer, thereby fixing the smoothed nonwoven fiber layer a second time and preventing the nonwoven fiber layer from deviating.

[0026] See Figure 6 The abutment mechanism 3 also includes a support plate 38; there are multiple support plates 38 respectively disposed on the side of the mold closing part 31, and the multiple support plates 38 are all located below the rubber part 37, and the support plate 38 has a cubic structure.

[0027] Specifically, it should be noted that after the non-woven fiber layer is smoothed and pressed against the housing, it can be supported by the support plate 38 to prevent the non-woven fiber layer from contacting the housing 1 after being pressed against the housing.

[0028] See Figures 3-5 The mold closing mechanism 4 includes a first moving mold 41, a second sliding mold 42, and a first linear drive mechanism 43; the first moving mold 41 is slidably disposed on the top of the housing 1 and is located beside the mold closing part 31; the second sliding mold 42 is slidably disposed on the housing 1 and is located below the mold closing part 31; the first linear drive mechanism 43 has a pair and is respectively disposed on the top of the housing 1.

[0029] Specifically, the first linear drive mechanism 43 includes a servo motor and a ball screw; the ball screw is threadedly connected to the first moving mold 41, and when the servo motor is started, it can drive the ball screw to rotate and move the first moving mold 41 toward the mold closing part 31. It stops after the first moving mold 41 moves above the mold closing part 31.

[0030] See Figure 1 The mold closing mechanism 4 also includes a first guide rail 44, a connecting part 45, and a swing arm 46; the first guide rail 44 has multiple parts and is respectively disposed on the top of the second sliding mold 42, and the first guide rail 44 is clearance-fitted with the housing 1; the connecting part 45 is disposed on the bottom of the housing 1; the swing part is rotatably disposed on the side of the connecting part 45, and one end of the swing arm 46 is rotatably connected to the second sliding mold 42.

[0031] Specifically, in order to raise the second sliding mold 42 and complete the mold closing action between it and the first moving mold 41 and the mold closing part 31, the connecting part 45 first drives the swing arm 46 to rotate. When the swing arm 46 rotates, it can drive the first guide rail 44 to move the second sliding mold 42 towards the mold closing part 31 along the clearance fit of the housing 1, until the second sliding mold 42 and the mold closing part are in contact and the mold closing action is completed.

[0032] See Figure 5 The mold closing mechanism 4 also includes a limiting part 47 and a telescopic cylinder 48; the limiting part 47 is disposed on the side of the connecting part 45 and is located on the outside of the housing 1; the telescopic cylinder 48 is rotatably disposed on the side of the housing 1 and is rotatably connected to the limiting part 47 at the output end of the telescopic cylinder 48.

[0033] Specifically, in order to reduce manual operation of the limiting part 47 to raise the second sliding mold 42 to complete the mold closing action, the telescopic cylinder 48 is first activated. When the telescopic cylinder 48 is activated, it can drive the rotating limiting part 47 and the connecting part 45 connected to the limiting part 47 to rotate, thereby realizing the raising and lowering of the second sliding mold 42.

[0034] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
