Description

Technical Field

[0001] The present invention relates to the field of plastic parts production, and in particular to intelligent manufacturing equipment for producing plastic housings of household appliances. Background Art

[0002] When producing plastic housings for home appliances, manufacturers often use hot-melt printing to print their own trademarks or unique designs on the housings to enhance the housing's aesthetics. However, in pursuit of aesthetic appeal, the housings of home appliances such as tea bar machines are not only flat but also have a certain curvature. When printing on curved housings, the curved plastic housings are difficult to fit the mold, resulting in incomplete printing and poor results. Existing methods usually force the embossing roller to apply pressure to the housing to deform it and fit it as closely as possible to the mold. This method can easily damage the housing and affect the quality of the finished product. Summary of the Invention

[0003] In order to overcome the shortcomings that the curved plastic shell is difficult to fit the mold, the printing is not comprehensive, the effect is poor, and the embossing roller is forced to press the shell to deform it to fit the mold, which easily damages the shell and affects the quality of the finished product, the present invention provides an intelligent manufacturing equipment for producing home appliance plastic shells.

[0006] In addition, it is particularly preferred that the supporting block and the corresponding limiting block are connected via a spring telescopic rod.

[0007] In addition, it is particularly preferred that the supporting block is wedge-shaped, and the two wedge-shaped supporting blocks are arranged opposite to each other.

[0008] In addition, it is particularly preferred that a moving rod is further included; the bottom of all sliding rods except those in the middle position is connected to a moving rod; the moving rod passes through the corresponding sliding rods from front to back; the rubber plate is composed of at least fourteen rubber blocks; every two rubber blocks correspond to one sliding rod; the two rubber blocks corresponding to the middle sliding rod are respectively slidably connected to the push rod tube of an electric push rod 2; and every other two rubber blocks are each slidably connected to a moving rod.

[0013] Furthermore, it is particularly preferred that the fur layer on the fur roller is fixed to the roller body by means of Velcro.

[0014] Beneficial effects: The present invention realizes that the curvature of the curved shell is adapted to the curvature of the curved shell by the rubber plate, so that multiple slide bars are arranged with the same curvature as the curved shell, and then the slide bars are squeezed one by one, so that the curved shell swings along its curved surface, and then the outer curved surface of the curved shell contacts the printing mold in different areas for printing.

[0029] It also includes an electric push rod 2 108, a limit block 7 and a supporting block 8; two electric push rods 2 108 are installed at the bottom of the slide rod 5 in the middle position of all the slide rods 5 in a front-to-back symmetrical manner; each electric push rod 2 108 is fixedly connected to a limit block 7 at the telescopic end, and the limit blocks 7 are located on both sides of the arc-shaped shell 1111 and in contact with the arc-shaped shell 1111, and each limit block 7 is connected to a supporting block 8 at the bottom; the supporting block 8 cooperates with the rubber plate 6 and the limit block 7 to limit the position of the arc-shaped shell 1111.

[0030] The supporting block 8 and the corresponding limiting block 7 are connected via a spring telescopic rod, so that the limiting block 7 and the supporting block 8 can limit the arc-shaped shells 1111 of different thicknesses.

[0031] The supporting block 8 is wedge-shaped, and the two wedge-shaped supporting blocks 8 are arranged opposite to each other; the inclined surface of the wedge-shaped supporting block 8 first contacts the arc-shaped shell 1111, thereby forcing the supporting block 8 to move away from the limit block 7 to adapt to the arc-shaped shell 1111 of different thicknesses.

[0034] The upper surface of the support bar 9 is provided with a rubber anti-slip layer to prevent the supporting arc-shaped shell 1111 from deflecting when embossing.

[0035] Four height-adjustable support legs are installed at the bottom of the workbench 1; when the present invention is placed on an inclined plane, the overall stability of the present invention can be increased by adjusting the height of the support legs.

[0036] The use steps of the present invention are as follows:

[0037] by Figure 1 For reference, the moving direction of the electric slider 3 107 is the front-to-back direction, and the moving direction of the electric slider 2 104 is the left-to-right direction.

[0038] Before practical use, the electric element of the present invention is powered. The printing mold 10 is a hot-melt metal part. After power is applied, the temperature is raised to the hot-melt temperature through resistance (taking low-density polyethylene as an example, the temperature is raised to 115°C). In the initial state, the electric push rod 105 is in an extended state, and the top surface of the support bar 9 is higher than the top of the printing mold 10. When embossing, the electric slider 107 is controlled to drive the support bar 9 to move along the guide rail 106. The distance between the two support bars 9 is adjusted to support the arc-shaped shell 1111 without blocking the area on the arc-shaped shell 1111 where printing is required. Then, the worker sews the outer surface of the arc-shaped shell 1111. The arc surface (embossed surface) is placed on the support bar 9 with the arc surface (embossed surface) facing down, and then the electric slider 102 is controlled to move downward along the guide rail 101, so that the mounting plate 2, N-shaped frame 3, pressure roller 4, slide rod 5 and rubber plate 6 move downward. During the process, the rubber plate 6 will contact the inner arc surface of the arc shell 1111. Since the inner arc surface is arc-shaped, the left and right sides of the rubber plate 6 first contact the arc shell 1111, so that the slide rods 5 on the left and right sides are blocked and cannot move downward. The mounting plate 2 will continue to move downward relative to the slide rod 5, while compressing the corresponding elastic member 502. The middle part of the rubber plate 6 will contact the arc shell 1111 at the latest, and finally as shown in FIG. Figure 4As shown, after the middle of the rubber plate 6 contacts the arc-shaped shell 1111, the rubber plate 6 is deformed into the same arc as the arc-shaped shell 1111, and each slide bar 5 is also arranged in an arc shape, and then the rubber sheet 501 on the top of the slide bar 5 is pushed and also deformed into a corresponding arc shape. At this time, the electric slider 102 stops moving downward, and all the slide bars 5 press the arc-shaped shell 1111 on the support bar 9 through the rubber plate 6. Then the electric push rod 105 is controlled to contract, so that the support bar 9 moves downward, and the electric slider 102 moves downward synchronously. , so that the slide bar 5 and the rubber plate 6 always press the arc-shaped shell 1111 on the support bar 9 until the upper surface of the support bar 9 is flush with or lower than the surface of the printing mold 10. The electric push rod 105 stops shrinking, and the electric slider 102 stops moving down. The middle part of the outer arc surface of the arc-shaped shell 1111 will first contact the printing mold 10 to emboss the middle area of ​​its outer arc surface; then the electric slider 2 104 is controlled to drive the pressure roller 4 to move back and forth left and right along the guide rail 2 103. When the pressure roller 4 moves to the left, The left side of the rubber sheet 501 is pressed down, and the sliding rods 5 on the left side are pressed down one by one. The sliding rods 5 on the left side press down the rubber plate 6 and the left side of the arc-shaped shell 1111, so that the left side of the arc-shaped shell 1111 moves down and contacts the printing mold 10. The right side of the arc-shaped shell 1111 is tilted and pushes the sliding rod 5 and the rubber plate 6 on the right side upward, and further compresses the corresponding elastic member 502, thereby embossing the left side of the outer arc surface of the arc-shaped shell 1111. When the pressing roller 4 moves to the right, the sliding rods 5 on the right side are pressed down one by one, so that The right side of the rubber plate 6 presses the right side of the arc-shaped shell 1111 downward, and the left side of the arc-shaped shell 1111 tilts up to push up the left slide bar 5, and embosses the right side of the outer arc surface of the arc-shaped shell 1111; in this way, the outer arc surface of the arc-shaped shell 1111 is in contact with the printing mold 10, and the embossing work is completed; then the electric push rod 105 is controlled to extend and the electric slider 102 is moved up, and the support bar 9 drives the arc-shaped shell 1111 to move up and disengage from the printing mold 10, and the electric slider 102 continues to move up and reset to Figure 1 The rubber sheet 6 is moved to its initial position, causing it to break away from contact with the arc-shaped shell 1111. After breaking away from the obstruction of the arc-shaped shell 1111, the elastic member 502 stretches, pushing the slide bar 5 downward, and each slide bar 5 returns to the same height in its initial state. After that, the worker can remove the printed arc-shaped shell 1111 from the support bar 9.

[0039] When the printing area is not front-to-back symmetrical, before the rubber block 601 moves down and contacts the curved shell 1111, the two electric push rods 108 are controlled to extend so that the front-to-back covering length of the two limit blocks 7 and the supporting block 8 is greater than the front-to-back length of the curved shell 1111. Then, the electric slider 102 is controlled to push the rubber block 601 to move down and fit with the curved shell 1111. Then, the two electric push rods 108 are controlled to contract so that the two limit blocks 7 contact the front and rear sides of the curved shell 1111, and the supporting block 8 contacts the bottom surface of the curved shell 1111, thereby fixing the curved shell 1111 on the middle slide bar 5 to maintain the front-to-back balance of the curved shell 1111. Then, the support bar 9 is controlled to move down below the printing mold 10. The electric slider 102 pushes the slide bar 5 and the rubber plate 6 to move down so that the curved shell 1111 contacts the printing mold 10 for printing.

[0040] When other raised structures are provided on the inner curved surface of the curved shell 1111, and the raised structures are located in the coverage area of ​​the rubber plate 6, before the rubber plate 6 moves down and contacts the curved shell 1111, according to the area where the obstruction structure is located, the worker slides the corresponding rubber block 601 along the moving rod 11 or the push rod tube of the electric push rod 2 108, so that the rubber block 601 moves forward or backward to avoid the obstruction structure, and then controls the electric slider 102 to move downward, driving the mounting plate 2, N-shaped frame 3, pressure roller 4, slide rod 5 and each rubber block 601 to move downward, so that each rubber block 601 contacts the curved shell 1111 and adapts to the shape of the curved shell 1111, and then squeezes the corresponding slide rod 5 through the pressure roller 4 to move the curved shell 1111 to perform printing.

[0041] According to the above steps, we know that the present invention has the following effects:

[0042] In order to address the problem that when printing on an arc-shaped plastic shell, the arc-shaped plastic shell is difficult to fit the mold, the printing is not comprehensive, and the effect is poor, and forced pressure on the shell causes it to deform, which easily damages the shell and affects the quality of the finished product, the present invention adapts the curvature of the arc-shaped shell 1111 through the rubber plate 6, so that multiple slide bars 5 are arranged with the same curvature as the arc-shaped shell 1111, and then squeezes the slide bars 5 one by one, so that the arc-shaped shell 1111 swings along its arc surface, and then the outer arc surface of the arc-shaped shell 1111 contacts the printing mold 10 in sections for printing. There is no need to use external force to force the arc-shaped shell 1111 to deform, and the printing operation is carried out by fitting the printing mold 10, thereby avoiding deformation of the arc-shaped shell 1111 and damage, which affects the quality.

[0043] When the printing pattern is a front-to-back asymmetrical pattern, when the arc-shaped shell 1111 moves down and contacts the printing mold 10, the contact portion of the arc-shaped shell 1111 and the printing mold 10 will be supported by it, and at this time the support bar 9 continues to move down below the top surface of the printing mold 10, and the portion of the arc-shaped shell 1111 that is not in contact with the printing mold 10 (non-printing area) has no support, causing the arc-shaped shell 1111 to tilt, and then causing the front and back heights of the downward-moving arc-shaped shell 1111 to be inconsistent, affecting the molding quality of the hot-melt-molded printing pattern; therefore, after the rubber block 601 contacts the arc-shaped shell 1111, the present invention fixes the arc-shaped shell 1111 and the middle slide bar 5 together through the limit block 7 and the support block 8, maintaining the front and back balance of the arc-shaped shell 1111, so that when the arc-shaped shell 1111 moves down and contacts the asymmetric printing mold 10, it does not tilt, thereby avoiding affecting the quality of hot-melt printing.

[0044] When the inner curved surface of the curved housing 1111 is provided with reinforcing ribs, the rubber sheet 6 in contact therewith will deform adaptively. However, when the inner curved surface is provided with other protruding structures, the protruding structures are located within the coverage area of ​​the rubber sheet 6, and the deformation degree of the rubber sheet 6 is insufficient to adapt to the protruding structures, which will hinder the rubber sheet 6 from contacting the inner curved surface of the curved housing 1111. Therefore, by moving the rubber blocks 601 that constitute the rubber sheet 6 to avoid the obstructing structures, each rubber block 601 is then brought into contact with the curved housing 1111, adapting to the shape of the curved housing 1111, and avoiding the protruding structures from hindering the rubber sheet 6 from contacting the inner curved surface of the curved housing 1111.

[0045] The additional technical effects of the present invention are as follows:

[0046] like Figure 3 As shown, the supporting block 8 and the corresponding limiting block 7 are connected by a spring telescopic rod, so that the distance between the limiting block 7 and the supporting block 8 can be adjusted, and the arc-shaped shell 1111 of different thicknesses can be adaptively limited.

[0047] Example 2: Based on Example 1, Figure 1 and Figure 2 As shown, a fur roller 12 is also included; a fur roller 12 is connected to the two guide rails 3 106 and the corresponding electric sliders 3 107 for common rotation; each fur roller 12 is located under a support bar 9.

[0048] The fur layer on the fur roller 12 is fixed to the roller body by Velcro, which makes it easy for workers to remove the dirty fur for cleaning.

[0049] The operating steps of this embodiment are as follows:

[0050] After each printing work is completed, the worker removes the arc-shaped shell 1111 from the support bar 9, controls the extension length of the electric push rod 105, so that the lowest point of the fur roller 12 is flush with the top of the printing mold 10, and then controls the electric slider 3 107 to move along the guide rail 3 106, driving the fur roller 12 to roll over the surface of the printing mold 10, and cleans the surface of the printing mold 10 before the next printing work.

[0051] According to the above steps, we know that the present invention also has the following effects:

[0052] When the printing area of ​​the printing mold 10 is large, dust is easily dropped from the surface of the printing mold 10, and plastic debris remaining on the arc-shaped shell 1111 is also easy to fall onto the printing mold 10. The heat of the printing mold 10 causes the plastic debris to melt on its surface, which is inconvenient to remove and affects the next printing. In the present invention, the fur roller 12 rolls over the surface of the printing mold 10 to remove the dust on the printing mold 10. At the same time, the fur-surfaced printing mold 10 can adhere to the plastic debris melted on the surface of the printing mold 10 and remove it from the surface of the printing mold 10, thereby keeping the printing mold 10 clean and avoiding affecting the next printing. At the same time, the height of the fur roller 12 can be adjusted in conjunction with the extension and retraction of the electric push rod 105 to adapt to the different height positions of the printing mold 10 for cleaning.

[0053] It should be understood that this embodiment is only used to illustrate the present invention and is not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall equally within the scope limited by the appended claims of the application.
