Description

Technical Field

[0001] This utility model relates to the field of carving material feeding technology, specifically an adjustable material box and feeding assembly. Background Technology

[0002] Sculpture is a process of gradually revealing a form by removing waste material, working from the outside in. As human needs continue to grow, the slow speed and low efficiency of traditional hand carving have become increasingly prominent, failing to meet the demands of modern life. There is an urgent need to improve the speed and quality of carving, leading to the development of carving robots.

[0003] To automate the feeding of carving robots and improve their carving efficiency, the applicant previously filed a patent application with Chinese Patent Publication No. CN216177600U entitled "A Feeding Component for a Carving Robot." Its main content is as follows: A storage cavity is constructed within a material cassette to accommodate stacked carving pieces. A lifting arm, extendable along the length of the cassette, enters the cassette at its lifting end and then extends vertically upwards to support the bottom carving piece within the storage cavity, thereby achieving automated feeding of the carving pieces.

[0004] The automatic feeding of the carving discs in the above-mentioned solution significantly improves the carving efficiency of the carving robot. However, with the development of the carving industry, the shape and structure of the carving discs have gradually diversified, and there are even irregularly shaped carving discs. When the shape and structure of the carving discs change, it is often necessary to replace them with new material bins that are compatible with the shape and structure of the carving discs, which obviously increases the cost of the device. Therefore, based on the above application, the applicant is also considering further research and development of material bin structure improvements to ensure greater adaptability to the shape and structure of the carving discs while maintaining structural simplicity. Utility Model Content

[0005] In order to avoid and overcome the technical problems existing in the prior art, this utility model provides an adjustable material box and feeding assembly, which has a simple structure and greater adaptability to the shape contour of the engraving sheet.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adjustable material tray includes a frame arranged on a machine frame. From a top view, the inner side of the frame has a rectangular structure with an adjustable long side length or wide side width. Four vertically arranged guide bars are arranged on the inner side of the frame. The cross-section of the guide bars is a right-angle structure, and the four guide bars are respectively installed at the four corners of the inner side of the frame. The guide bars can be adjusted horizontally along the two side walls of their respective corners. The right-angled inner sides of the four guide bars together form an adjustable placement cavity for stacking engraved pieces layer by layer.

[0008] As a further embodiment of the present invention: the frame includes a first frame constituting three sides or two adjacent sides of the rectangular structure, and the frame also includes a second frame constituting one side of the rectangular structure. A long hole with a hole pattern arranged horizontally in the length direction is provided on the side of the first frame perpendicular to the second frame. A first bolt passing through the long hole is fixed on the fixed end of the second frame, and the first frame and the second frame are locked and fixed by the first bolt.

[0009] As a further improvement of this utility model: all side walls of the frame are provided with elongated holes arranged horizontally in the length direction of the hole, and mounting holes are provided at the same height as the elongated holes on the two right-angled sides of the guide strip. The mounting holes on any right-angled side of the guide strip and the elongated holes on the corresponding side walls of the frame can be sequentially passed through by a second bolt to fix the guide strip and the frame to each other.

[0010] As a further embodiment of this utility model: the frame is configured as two frames arranged at an interval, one above the other, with the two frames respectively located at the upper and lower parts of the guide bar, and the frame is fixed to the two frames respectively by two brackets.

[0011] The feeding assembly uses an adjustable material box, which includes a lifting head that can lift and lower. The lifting head slides into the adjustable placement cavity from bottom to top and supports the lowest layer of engraved sheet in the adjustable placement cavity; and the top opening of the adjustable placement cavity forms a discharge port for the engraved sheet to be discharged.

[0012] As a further improvement of this utility model: a screw-slider mechanism for driving the lifting head to perform lifting and lowering actions is arranged on the side of the frame, and the slider of the screw-slider mechanism is fixed to the lifting head through a connecting part; the frame is provided with an avoidance break to avoid the lifting and lowering movement of the connecting part.

[0013] As a further improvement of this utility model: the bottom of the adjustable placement cavity is provided with a base plate, which initially supports the engraved piece inside the adjustable placement cavity, and the base plate is provided with a clearance opening to avoid the lifting head from sliding up and down.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The adjustable placement cavity has a cross-sectional structure adjustment method with a first adjustment method that only slides the guide bar horizontally along the inner wall of the frame, a second adjustment method that only adjusts the length of the long side or the width of the short side of the rectangular structure, and a third adjustment method that combines the first and second adjustment methods.

[0016] The three adjustment methods in this invention enable the adjustable placement cavity to adapt well to the contours of irregularly shaped carving pieces of different sizes. Specifically, based on the actual shape of the carving piece, the position of the guide strip is adjusted using the above three methods. This allows the guide strip to move beyond the four corners of the rectangular structure. By adjusting the guide strip, both right-angled sides of all guide strips can be made to fit and abut against the outer contour of the carving piece. This ensures that at least eight points of contact and positioning are achieved on the outer periphery of carving pieces with different outer contours, resulting in a good positioning effect for carving pieces with different contours.

[0017] 2. The adjustment of the long side length or short plate width of the rectangular structure, as well as the sliding adjustment of the guide bar, are all achieved by unlocking the nut on the bolt, sliding the bolt's thread along the length of the long hole, and finally tightening the nut. This adjustment method has a large adjustment stroke and is convenient and quick.

[0018] 3. The frame is set as two, spaced apart vertically, with the two frames positioned above and below the guide bar. This not only ensures the stable fixation of the guide bar, but the gap between the two frames can also be used to observe the state of the engraved piece inside the adjustable placement cavity formed by the guide bar, and the gap between the two frames can be used to adjust unevenly placed engraved pieces.

[0019] 4. The lifting head is driven up and down by a screw and slider mechanism to push the engraved piece out. This does not take up too much vertical space, and the adjustment stroke is large and the stability is high.

[0020] 5. The adjustable placement chamber is equipped with a base plate at the bottom. The base plate initially supports the engraved pieces inside the adjustable placement chamber, so that in the initial state, the engraved pieces do not need to rely entirely on the lifting head for support. Therefore, during the feeding process, the adjustable hoppers can be set up to work in two alternating sets. When the working adjustable hopper has finished feeding the engraved pieces, the adjustable hopper can be disassembled, and a new adjustable hopper loaded with engraved pieces can be installed on the frame, thereby improving the overall feeding efficiency.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] For ease of understanding, the specific structure and working method of this utility model are further described below with reference to the accompanying drawings:

[0033] The specific structure of this utility model is as follows: Figure 1-9 As shown, the adjustable material box mainly includes a frame 10 arranged on the frame 40 and four guide bars 20 that enclose and form an adjustable placement cavity; the feeding assembly using the adjustable material box mainly includes a lifting head 51 that pushes the engraved pieces out of the adjustable placement cavity.

[0034] 1. Adjustable feeder

[0035] like Figure 1-8As shown, from a top-down view, the inner side of the frame 10 has a rectangular structure with adjustable long or short sides. Four vertically arranged guide bars 20 are positioned on the inner side of the frame 10. The cross-section of each guide bar 20 is a right-angled structure, and the four guide bars 20 are respectively installed at the four corners of the inner side of the frame 10. Each guide bar 20 can be horizontally slid along the two side walls of its corresponding corner of the frame 10. The right-angled inner sides of the four guide bars 20 together form an adjustable placement system for stacking engraved pieces layer by layer. In this invention, the adjustable placement cavity's cross-sectional structure can be adjusted in three ways: a first adjustment method where the guide bars 20 are slid horizontally along the inner wall of the frame 10; a second adjustment method where only the long or short side of the rectangular structure is adjusted; and a third adjustment method combining the first and second adjustment methods. Currently, even with adjustment structures for the cavity containing the carving piece, most methods, such as the first adjustment method, adjust the length of the long or short side of the rectangular structure. This method is only suitable for rectangular carving pieces of different sizes. However, the three adjustment methods in this invention allow the resulting adjustable cavity to adapt well to irregularly shaped carving pieces of different sizes. Specifically, based on the actual outline of the carving piece, the position of the guide strip 20 is adjusted using the three methods described above. This allows the guide strip 20 to be positioned beyond the four corners of the rectangular structure. By adjusting the guide strip 20, both right-angled sides of all guide strips 20 can be made to fit and abut against the outer contour of the carving piece. This ensures at least eight points of contact and positioning on the outer periphery of carving pieces with different outer contours, achieving a good positioning effect for carving pieces with different contours.

[0036] Specifically, such as based on the external shape or outline, such as Figure 4 As shown, by using the third adjustment method described above, the outer periphery of the first-style engraved piece a1, whose length and width are both smaller than the maximum length and width of the rectangular structure, was properly fitted and positioned. Figure 5 As shown, by using the second adjustment method described above, the outer periphery of the second-style engraved piece a2, whose length is less than the maximum length of the rectangular structure, was properly fitted and positioned. Figure 6 and Figure 7 As shown, the first adjustment method can be used to position and fit the outer periphery of the irregularly shaped third-style engraved piece a3 and fourth-style engraved piece a4. Figure 8 As shown, the third adjustment method can be used to fit and position the outer periphery of the irregular fifth style engraving piece a5, which is smaller than the third style engraving piece a3.

[0037] like Figure 2As shown, the frame 10 includes a first frame 11 forming three sides or two adjacent sides of a rectangular structure, and a second frame 12 forming one side of the rectangular structure. An elongated hole 13, horizontally arranged in the length direction of the hole, is provided on the side of the first frame 11 perpendicular to the second frame 12. A first bolt passing through the elongated hole 13 is fixed to the fixed end of the second frame 12, locking the first frame 11 and the second frame 12 together. During adjustment, the nut on the first bolt is unlocked, and the screw of the first bolt is slid within the elongated hole 13 along the length direction of the hole, thus adjusting the position of the second frame 12. After adjustment, the nut on the first bolt is tightened, thereby adjusting the length of the long side or the width of the short side of the rectangular structure. This adjustment method has a large adjustment stroke and the adjustment process is convenient and quick.

[0038] like Figure 3 As shown, all side walls of the frame 10 are provided with elongated holes 13 arranged horizontally along their length. Mounting holes 21 are provided at the same height as the elongated holes 13 on both right-angled sides of the guide strip 20. The mounting holes 21 on any right-angled side of the guide strip 20 and the corresponding elongated holes 13 on the side walls of the frame 10 can be sequentially connected by a second bolt to fix the guide strip 20 to the frame 10. Similar to the adjustment method of the second frame 12 described above, both have the advantages of a large adjustment range and convenient and quick adjustment. The difference is that the guide strip 20 can slide and adjust along the length of its two right-angled sides. In actual implementation, when adjustment is needed along the length of a particular right-angled side, the second bolt is simply inserted into the corresponding mounting hole 21 on that right-angled side.

[0039] In the above scheme, since one of the adjustment directions of the guide bar 20 is the same as the adjustment direction of the second frame 12, in actual implementation, if... Figure 2 and Figure 3 As shown, the elongated holes 13 used for adjusting the guide bar 20 and the second frame 12 in this adjustment direction can share a single elongated hole 13.

[0040] Based on the above, two frames 10 are arranged at an interval, one above the other, with the two frames 10 positioned above and below the guide bar 20, respectively. The frame 40 is fixed to the two frames 10 via two supports 41. The arrangement of the two frames 10 above and below the guide bar 20 not only ensures stable fixation of the guide bar 20, but the interval between the two frames 10 also allows for observation of the state of the engraved piece within the adjustable placement cavity formed by the guide bar 20, and adjustment of unevenly placed engraved pieces can be made using the interval between the two frames 10.

[0041] 2. Feeding components

[0042] like Figure 9As shown, the feeding assembly includes a lifting head 51 capable of lifting. The lifting head 51 slides upward into the adjustable placement cavity and supports the lowest layer of engraved pieces within the cavity. The top opening of the adjustable placement cavity forms a discharge port for the engraved pieces to exit. By sliding the lifting head 51 upward within the adjustable placement cavity by the thickness of one engraved piece, all the engraved pieces can be lifted upward by the thickness of one engraved piece, allowing the uppermost engraved pieces to exit sequentially. In practice, the distance the lifting head 51 slides in one stroke is the same as the thickness of the engraved piece, thus achieving stable feeding of engraved pieces of different thicknesses.

[0043] Of course, in actual implementation, a bottom discharge method can also be adopted. Specifically, the adjustable hopper can be arranged directly above the feeding platform. The bottom of the adjustable hopper and the surface of the feeding platform have a discharge gap equal to the thickness of one engraving piece, and the discharge port is formed by the bottom opening of the adjustable placement cavity. In this case, the feeding assembly can include a horizontally reciprocating pusher. The pusher has a flat structure, and its thickness is less than or equal to the thickness of one engraving piece. By facing the pusher upward and sliding it directly below the adjustable placement cavity, the lowermost engraving piece in the adjustable placement cavity can be pushed out horizontally. When the pusher slides back to its original position and separates from the lower part of the adjustable placement cavity, all the engraving pieces descend by the thickness of one engraving piece under the action of gravity. After that, the continuous reciprocating sliding of the pusher can realize the continuous feeding of engraving pieces.

[0044] Based on the above, such as Figure 9 As shown, a screw-slider mechanism 50 for driving the lifting head 51 to move up and down is arranged on the side of the frame 10. The slider of the screw-slider mechanism 50 is fixed to the lifting head 51 through a connecting part. The frame 10 is provided with a clearance break 14 to avoid the lifting movement of the connecting part. Using the screw-slider mechanism 50 to drive the lifting head 51 to move up and down does not occupy too much vertical space, and has the advantages of large adjustment stroke and high stability.

[0045] It is worth mentioning that in the embodiment where the frame 10 is formed by the combination of the first frame 11 and the second frame 12, if the first frame 11 is set as two adjacent sides constituting the rectangular structure, and the second frame 12 is set as one side constituting the rectangular structure, such as... Figure 2 As shown, assuming the second frame 12 is arranged perpendicular to the long side of the first frame 11, then the clearance 14 can be formed by the gap between the cantilever end of the second frame 12 and the cantilever end of the short side of the first frame 11.

[0046] Of course, if there is sufficient vertical space at the installation location, the lifting head 51 can be raised and lowered by a cylinder or hydraulic cylinder located directly below the adjustable placement cavity. In this case, there is no need to provide a clearance break 14. In this embodiment where the frame 10 is formed by the combination of the first frame 11 and the second frame 12, the first frame 11 can be configured as three sides constituting a rectangular structure, and the second frame 12 can be configured as one side constituting a rectangular structure.

[0047] Based on the above, such as Figure 3 As shown, a base plate 30 is provided at the bottom of the adjustable placement cavity. The base plate 30 initially supports the engraved pieces inside the adjustable placement cavity, and a clearance opening 31 is provided on the base plate 30 to allow the lifting head 51 to slide and move. Because of the base plate 30, the engraved pieces inside the adjustable placement cavity do not need to rely entirely on the lifting head 51 for support in the initial state. Therefore, during the feeding process, the adjustable hoppers can be configured as two sets working alternately. When the working adjustable hopper has finished feeding the engraved pieces, the adjustable hopper is disassembled, and a new adjustable hopper loaded with engraved pieces is installed on the frame 40, thereby improving the overall feeding efficiency.

[0048] Of course, those skilled in the art will recognize that this invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0049] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
