Description

Technical Field

[0001] This utility model relates to the field of rotary drilling machine technology, and in particular to a support plate for rotary drilling platform. Background Technology

[0002] A rhinestone applicator is a processing device that arranges and securely adheres rhinestones to fabric, adhesive tape, or other materials according to a preset pattern. Subsequent processing of the fabric, adhesive tape, or other materials facilitates the creation of garments with various exquisite rhinestone patterns. During operation, the rhinestones are supported in a pile on the applicator's platform. The platform is driven to shake the pile, allowing the rhinestones to enter the drill holes of a template on the platform and be attracted to them, arranging them into a preset pattern. The upper side of the template has drill holes for accommodating the rhinestones, and the lower side has air holes communicating with the drill holes to create negative pressure that attracts the rhinestones.

[0003] Chinese utility model patent CN220734521U discloses a rotary drilling machine. The rotary drilling platform of this machine includes a mounting plate, a template is positioned above the mounting plate, the mounting plate has a through hole, the template has a mounting hole (i.e., a drilling hole), and an air hole is provided at the bottom of the mounting hole. The through hole connects the air hole to the cavity of the rotary drilling platform. Although the aforementioned patent discloses a technical solution of placing the template above the mounting plate, the structure of its mounting plate has defects.

[0004] The aforementioned mounting plate is formed from a sheet material with a horizontal upper surface, through which only through holes are drilled. When the template is placed on top of the mounting plate, there is a large and continuous contact surface between the template and the mounting plate. It is essential to ensure that each vent on the template corresponds to and aligns with a through hole on the mounting plate, allowing direct communication between the vent and the corresponding through hole. Otherwise, some vents will inevitably be blocked or obstructed by the mounting plate, making it impossible to effectively attract decorative drills at the corresponding drill holes, or even completely preventing the attraction of decorative drills, resulting in missed drill holes. In other words, the aforementioned mounting plate imposes strict limitations and requirements on the location of the vents in the template and the accuracy of template placement. It not only restricts the location of the vents to strictly follow the dot matrix positions of the through holes, but also requires that the template be placed without misalignment or angular deviation. However, the location of the vents in different templates is determined by a preset pattern, and the patterns vary widely, making it impossible to drill holes and vents exactly according to the dot matrix positions of the through holes.

[0005] Therefore, the mounting plates described above have poor versatility. For many patterns, the templates cannot be adapted to these mounting plates. Utility Model Content

[0035] The following description is provided to enable those skilled in the art to implement the present invention. Other obvious substitutions, modifications, and variations will arise in the mind of those skilled in the art. Therefore, the scope of protection of the present invention should not be limited to the exemplary embodiments described herein.

[0036] Those skilled in the art will understand that, unless specifically indicated herein, the term "a" should be understood as "at least one" or "one or more," meaning that in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple.

[0037] Those skilled in the art should understand that, unless specifically indicated herein, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., refer to the orientation or position based on the accompanying drawings, and are merely for the convenience of describing the present invention, and do not indicate or imply that the device or element involved must have a specific orientation or position. Therefore, the above terms should not be construed as limiting the present invention.

[0038] Refer to the accompanying drawings in this utility model specification. Figures 1 to 9 A support plate for a rotary drilling rig according to an embodiment of the present invention is described. The support plate 1 has a support side 101 and a back side 102, with the support side 101 and the back side 102 being opposite sides of the support plate 1. The support plate 1 is mounted on the rotary drilling rig, with the back side 102 of the support plate 1 facing the negative pressure chamber of the rotary drilling rig. A template 2 is adapted to be placed on the support plate 1 and supported by the support plate 1 on the support side 101.

[0039] It is worth mentioning that the template 2 has interconnected drill holes 21 and air holes 22, with the air holes 22 located below the drill holes 21. The drill holes 21 are used to accommodate decorative rhinestones, and by creating a negative pressure at the air holes 22, the decorative rhinestones are adsorbed onto the drill holes 21. It is also worth mentioning that the diameter of the air holes 22 is smaller than the diameter of the drill holes 21.

[0040] like Figures 2 to 9As shown, the support plate 1 has multiple first channels 11 and multiple second channels 12. The first channels 11 are located on the back side 102 of the support plate 1 and are adapted to communicate with the negative pressure chamber of the rotary drilling platform. The second channels 12 are located on the support side 101 of the support plate 1, and the first channels 11 communicate with corresponding second channels 12. By providing the second channels 12, the air holes 22 of the template 2 can be indirectly connected to the first channels 11 of the support plate 1, thus eliminating the requirement that each air hole 22 on the template 2 be aligned with one of the first channels 11 of the support plate 1. Figure 5 As shown, even if the air hole 22 is misaligned and not aligned with the first channel 11 in the vertical direction, the air hole 22 and the first channel 11 can still be connected through the corresponding second channel 12. Therefore, the opening position of the air hole 22 of the template 2 is no longer limited by the opening point of the first channel 11, thereby enabling the support plate 1 to be adapted to templates with various patterns, and has strong versatility.

[0041] In some embodiments of this invention, the second channels 12 of the support plate 1 can be fully interconnected, which helps to uniformly form negative pressure at each of the air holes 22. In some embodiments of this invention, the second channels 12 of the support plate 1 can also be connected in groups, with the second channels 12 in the same group interconnected and those in different groups not interconnected. It is understood that having all the second channels 12 interconnected or connected in groups helps to reduce the number of the first channels 11, thus reducing manufacturing difficulty and cost. In the most extreme case, having all the second channels 12 interconnected allows the number of the first channels 11 to be reduced to a minimum of one, while having the second channels 12 connected in groups allows the number of the first channels 11 to be reduced to a minimum of the number of groups, with each group corresponding to one first channel 11. Of course, the more first channels 11 there are, the more beneficial it is to uniformly form negative pressure. In practical applications, the appropriate number of first channels 11 can be designed according to the actual situation.

[0042] In some embodiments of this utility model, the second channels 12 of the support plate 1 may also be disconnected from each other, that is, any two second channels 12 are not connected. In this way, the number of the first channels 11 needs to be the same as the number of the second channels 12 to ensure that the first channels 11 and the second channels 12 can be connected in a one-to-one correspondence.

[0043] like Figures 2 to 9As shown, the support plate 1 further includes at least one support portion 13, which is disposed on the support side 101 of the support plate 1. The support portion 13 is used to flatly support the template 2. It is understood that since the template 2 needs to be frequently replaced to change the arrangement pattern of the rhinestones, the template 2 is usually made of thin and easily processed sheet material, which is difficult to maintain flatness on its own and is prone to deformation, making it difficult to arrange the rhinestones into a preset pattern. Therefore, supporting the template 2 with the support portion 13 of the support plate 1 helps maintain the flatness of the template 2.

[0044] However, a portion of the support portion 13 may be located directly below some of the vents 22. To avoid the support portion 13 excessively obstructing the vents 22 and to reduce the probability of the support portion 13 obstructing the vents 22, the cross-sectional dimension of the support portion 13 decreases along the direction closer to the template 2. In other words, the cross-sectional dimension of the support portion 13 decreases along the direction from the back side 102 to the support side 101. It is worth mentioning that the term "cross-section" does not specifically refer to a section taken with a plane parallel to the horizontal plane, but should be understood as a section taken with a plane parallel to the plane where the template 2 is located. It is also worth mentioning that the reduction in the cross-sectional dimension of the support portion 13 should not be regarded as a restriction on its continuous reduction, but should be understood as a reduction trend in the overall direction, including, for example, a phased reduction. In other words, the core concept behind reducing the cross-sectional size of the support portion 13 lies in reducing the contact area between the support portion 13 and the template 2. By forming a very small surface contact, or near point contact or line contact, between the support end 131 of the support portion 13 and the template 2, excessive obstruction of the air hole 22 by the support end 131 is avoided, thus ensuring that the rhinestone can be reliably adsorbed and preventing missed rhinestones. The support end 131 is the end of the support portion 13 extending along the back side 102 towards the support side 101. Based on this, the support plate 1 can be applied to scenarios where the rhinestone size is smaller, i.e., the air hole 22 size is smaller, thus having greater versatility.

[0045] like Figures 2 to 5 As shown, in a specific embodiment of this utility model, the support plate 1 includes a plurality of support portions 13, the support ends 131 of the support portions 13 being pointed, and the contact between the support ends 131 and the template 2 is close to point contact. The support ends 131 of the plurality of support portions 13 are located within a support plane, and by forming a contact point array through an appropriate number of point contacts, the template 2 can be supported smoothly. More specifically, in this embodiment, the support side 101 of the support plate 1 is constructed in a wave shape, and the support ends 131 are located at the crest of the wave.

[0046] like Figure 6 and Figure 7 As shown, in a specific embodiment of this utility model, the support plate 1 includes a plurality of support portions 13, the support ends 131 of the support portions 13 being pointed, and the contact between the support ends 131 and the template 2 is close to line contact. The support ends 131 of the plurality of support portions 13 are located in the same support plane, and by forming a contact line array through an appropriate number of line contacts, the template 2 can be supported flatly. More specifically, in this embodiment, the support portion 13 is constructed as a triangular prism or similar to a triangular prism, and the support ends 131 are located at the side edges.

[0047] It is understood that in some embodiments of this utility model, a portion of the support end 131 forms point contact with the template 2, while another portion of the support end 131 forms line contact with the template 2.

[0048] like Figure 8 and Figure 9 As shown, in a specific embodiment of this utility model, the support plate 1 has only one support portion 13, and the support end 131 of the support portion 13 is a pointed tip. The contact between the support end 131 and the template 2 is close to a line contact. Each of the support ends 131 is located within a support plane, thus forming a network of contact lines through intersecting line contacts, which can also smoothly support the template 2. More specifically, in this embodiment, the second channel 12 is frustum-shaped, and the support end 131 is mesh-like. Moreover, in this embodiment, any two second channels 12 are not connected.

[0049] Understandably, although Figure 8 and Figure 9 In the specific embodiment shown, the support portion 13 is a mesh-like whole, and the support end 131 is also a mesh-like whole. However, in some modified embodiments, the support portion 13 can form multiple support ends 131. The support ends 131 can form point contact or line contact with the template 2, or a portion of the support ends 131 can form point contact with the template 2, and another portion of the support ends 131 can form line contact with the template 2.

[0050] In some embodiments of this invention, the support end 131 of the support portion 13 and the template 2 can also form a very small surface contact, as long as the support end 131 avoids excessively obstructing the air hole 22. Preferably, the area obstructed by the support end 131 of the air hole 22 is less than 50% of the area of ​​the air hole 22. To illustrate the obstruction of the air hole 22 by the support end 131 from another perspective, this invention selects a circular region at any position in the support plane, the diameter of which is the same as the diameter of the air hole 22, as an equivalent substitute for the air hole 22. Thus, the overlapping area of ​​the circular region and the support end 131 can be used as an equivalent substitute for the obstruction area of ​​the air hole 22 by the support end 131. Preferably, the overlapping area of ​​the circular region and the support end 131 is less than 50% of the area of ​​the circular region. Preferably, the diameter of the circular region is 1.2 mm. More preferably, the diameter of the circular region is 0.8 mm.

[0051] In particular, such as Figure 10 and Figure 11 As shown, in one embodiment of this utility model, there is no clear boundary between the first channel 11 and the second channel 12. However, the overall channel formed by them is still formed by the connection between the first channel 11 formed on the back side 102 and the second channel 12 formed on the support side 101. Moreover, in this embodiment, the support end 131 of the support portion 13 and the template 2 can also form line contact or a very small surface contact, which does not deviate from the core concept of this utility model. In other words, even if there is no clear boundary between the first channel 11 and the second channel 12, it does not exceed the protection scope of this utility model.

[0052] The specific shape and structure of the support side 101 of the support plate 1 shown in the accompanying drawings of this utility model are only examples and should not be regarded as a limitation on the specific shape and structure of the support side. Any shape and structure of the support side that does not deviate from the concept of this utility model should be included within the protection scope of this utility model.

[0053] It will be understood by those skilled in the art that the above embodiments are merely examples, and features of different embodiments can be combined with each other to obtain implementation methods that are readily conceived based on the content disclosed in this utility model but are not explicitly shown in the accompanying drawings.

[0054] Those skilled in the art should understand that the embodiments described above and illustrated in the figures are merely illustrative explanations of the present invention and are not intended to limit the scope of the invention. All equivalent implementations, modifications, and improvements within the spirit of the present invention should be included within the protection scope of the present invention.
