Description

Technical Field

[0001] This application relates to the field of printing equipment, and more particularly to a rigid frame and printing equipment. Background Technology

[0002] Printed materials are very common in daily life, such as brochures, newspapers, and product packaging. These printed materials are all produced by printing plants.

[0003] The printing head in printing equipment is mounted on a frame, which has a significant impact on the stable operation of the printing equipment. The frame generally consists of a base plate and several plates vertically connected to the base plate. To facilitate the connection with screws, metal blocks with connection holes are usually welded to one side of the plates, and then screws are inserted into the connection holes and screwed into the base plate.

[0004] Welding metal blocks onto the plate not only adds welding steps and occupies extra space on the base plate surface, but also results in a larger positional error between the plate and the base plate due to the superposition of positional errors between the metal blocks and the plate, leading to lower overall accuracy of the frame. Utility Model Content

[0005] This application provides a rigid frame and printing equipment, which can reduce manufacturing processes, save space on the base plate surface, and improve the frame's precision. The technical solution is as follows:

[0006] In a first aspect, embodiments of this application provide a rigid frame, the rigid frame including a base plate, a first wall plate, and a plurality of support plates, the first wall plate and the support plates being located on the same side of the base plate, the first wall plate being perpendicularly connected to the base plate, and the support plates being perpendicularly connected to the base plate and the first wall plate respectively.

[0007] The first wall panel has a plurality of first openings, and the first openings near the hole wall of the bottom plate are provided with first connecting holes extending to the bottom plate. A first connecting member is inserted into the first connecting hole and the first connecting member is connected to the bottom plate.

[0008] The support plate has a plurality of second openings. The second openings have a second connecting hole extending to the base plate near the hole wall of the base plate. A second connecting member is inserted into the second connecting hole and is connected to the base plate.

[0009] In some examples, the height of the first opening in the direction perpendicular to the base plate is not less than the length of the first connector;

[0010] The height of the second opening in the direction perpendicular to the base plate is not less than the length of the second connector.

[0012] In some examples, the rigid frame further includes a second wall panel and a plurality of wall panel support frames, the second wall panel being located on the side of the first wall panel away from the support plate, the second wall panel being arranged parallel to and opposite to the first wall panel, and being connected to the base plate;

[0013] The plurality of wall panel support frames are located between the first wall panel and the second wall panel, and are respectively connected to the first wall panel and the second wall panel.

[0014] In some examples, the second wall panel has a plurality of third openings, and the third openings near the wall of the base plate have a fourth connecting hole extending to the base plate. A fourth connector is inserted into the fourth connecting hole and is connected to the base plate.

[0015] In some examples, the first wall panel also has a plurality of fifth connection holes, in which fifth connectors are inserted and connected to the wall panel support frame;

[0016] The second wall panel also has a plurality of sixth connecting holes, in which a sixth connecting member is inserted, and the sixth connecting member is connected to the wall panel support frame.

[0017] In some examples, the rigid frame further includes a connecting block located on the side of the second wall panel near the first wall panel and connected to both the second wall panel and the base plate.

[0018] In some examples, the connecting block has a plurality of seventh connecting holes into which a seventh connector is inserted, the seventh connector being connected to the base plate.

[0019] In some examples, the base plate, the first wall plate, and the support plate are all castings.

[0021] The beneficial effects of the technical solutions provided in this application include at least the following:

[0022] By vertically connecting the first wall panel and the support plate on the same side of the base plate, with the support plate also vertically connected to the first wall panel, the first wall panel can be supported, reducing its lateral deformation and improving the overall stability of the rigid frame structure. A first opening is provided in the first wall panel, and a first connecting hole is provided in the wall of the opening.

[0037] Figure 1 This is a schematic diagram of a rigid frame structure provided in an embodiment of this application, as shown below. Figure 1 As shown, the rigid frame includes a base plate 10, a first wall plate 20, and a plurality of support plates 30. The first wall plate 20 and the support plates 30 are located on the same side of the base plate 10. The first wall plate 20 is perpendicularly connected to the base plate 10, and the support plates 30 are perpendicularly connected to the base plate 10 and the first wall plate 20, respectively.

[0038] Figure 2 This is a front view of a rigid frame provided in an embodiment of this application, such as... Figure 2 As shown, the first wall panel 20 has a plurality of first openings 20a, and the first opening 20a near the hole wall of the bottom plate 10 has a first connecting hole 20b extending to the bottom plate 10. Figure 3 yes Figure 2 Section I-I in the diagram, as shown Figure 3 As shown, a first connector 41 is inserted into the first connecting hole 20b, and the first connector 41 is connected to the base plate 10. For ease of demonstration of some structures, Figure 1 and Figure 2 Some features have been omitted, for example, to facilitate the demonstration of the first connecting hole 20b. Figure 1 and Figure 2 The first connector 41 is omitted.

[0039] like Figure 1 As shown, the support plate 30 has a plurality of second openings 30a, and the second openings 30a near the hole wall of the base plate 10 have second connecting holes 30b extending to the base plate 10. Figure 3 As shown, a second connector 42 is inserted into the second connecting hole 30b, and the second connector 42 is connected to the base plate 10.

[0040] By vertically connecting the first wall panel 20 and the support plate 30 on the same side of the base plate 10, with the support plate 30 also vertically connected to the first wall panel 20, the first wall panel 20 can be supported, reducing its lateral deformation and improving the overall stability of the rigid frame structure. By providing a first opening 20a in the first wall panel 20 and a first connecting hole 20b in the wall of the opening 20a, and connecting it to the base plate 10 using a first connector 41 inserted into the first connecting hole 20b, the first wall panel 20 is connected to the base plate 10 without welding a metal block to the surface of the first wall panel 20, thus eliminating the need for additional space on the surface of the base plate 10. Similarly, by providing a second opening 30a in the support plate 30 and a second connecting hole 30b in the wall of the opening 30a, and connecting it to the base plate 10 using a second connector 42 inserted into the second connecting hole 30b, the support plate 30 is connected to the base plate 10 without welding a metal block to the surface of the support plate 30, thus eliminating the need for additional space on the surface of the base plate 10. Both the first wall panel 20 and the support plate 30 are directly connected to the base plate 10, which helps to improve the accuracy of the rigid frame.

[0041] In some examples, the first connector 41 and the second connector 42 can be screws, and the first connector 41 and the second connector 42 are respectively threaded to the base plate 10.

[0042] The first wall panel 20 can be a rectangular plate, and the first opening 20a can be arranged near the side of the first wall panel 20 close to the base plate 10. That is, the distance from the first opening 20a to the side of the first wall panel 20 close to the base plate 10 is less than the distance to the side of the first wall panel 20 away from the base plate 10, so as to avoid the first connecting hole 20b being too long and affecting the connection between the first wall panel 20 and the base plate 10.

[0043] There can be multiple first openings 20a, and the multiple first openings 20a are arranged at intervals along the side of the first wall plate 20 near the bottom plate 10. For example, there can be two first openings 20a.

[0044] The first opening 20a can be a polygonal hole, such as a rectangular hole. The wall of the first opening 20a near the base plate 10 can be a flat surface, and the first connecting hole 20b is located on the wall of the first opening 20a near the base plate 10. The wall of the first opening 20a away from the base plate 10 can be a curved surface, such as a curved concave surface.

[0045] The support plate 30 can be a quadrilateral or a pentagonal plate. For example, the support plate 30 can be a right trapezoidal plate, or a pentagonal plate formed by cutting off the smaller base angle of a right trapezoidal plate. Taking the right trapezoidal support plate 30 as an example, the lower base of the trapezoidal plate can be attached to the first wall plate 20, and the right-angled leg of the trapezoidal plate can be attached to the base plate 10.

[0046] The second opening 30a can be arranged near the side of the support plate 30 close to the base plate 10. That is, the distance from the second opening 30a to the right-angled waist of the support plate 30 is less than the distance from the second opening 30a to the connection point between the bottom of the support plate 30 and the inclined waist. This avoids the second connecting hole 30b being too long and affecting the connection between the support plate 30 and the base plate 10.

[0047] Each support plate 30 may have a plurality of second openings 30a, which are spaced apart along the side of the support plate 30 near the base plate 10. For example, there may be two or three second openings 30a.

[0048] The second opening 30a can be a polygonal hole, such as a rectangular hole. The wall of the second opening 30a near the base plate 10 can be a plane, and the second connecting hole 30b is located on the wall of the second opening 30a near the base plate 10.

[0049] The length of the side of the support plate 30 that is in contact with the first wall panel 20 can be no less than half the height of the first wall panel 20, and the height direction of the first wall panel 20 is perpendicular to the base plate 10. Setting the length of the support plate 30 to be relatively large allows the support plate 30 to provide more stable support for the first wall panel 20.

[0050] In some examples, the height of the first opening 20a in the direction perpendicular to the base plate 10 is not less than the length of the first connector 41. The height of the second opening 30a in the direction perpendicular to the base plate 10 is not less than the length of the second connector 42.

[0051] The height of the first opening 20a in the direction perpendicular to the base plate 10 refers to the dimension of the first opening 20a in the direction perpendicular to the base plate 10, and not the vertical distance between the first opening 20a and the surface of the base plate 10; the height of the second opening 30a in the direction perpendicular to the base plate 10 refers to the dimension of the second opening 30a in the direction perpendicular to the base plate 10, and not the vertical distance between the second opening 30a and the surface of the base plate 10.

[0052] Setting the height of the first opening 20a perpendicular to the base plate 10 to be no less than the length of the first connector 41 facilitates the insertion of the first connector 41 into the first connecting hole 20b. Similarly, setting the height of the second opening 30a perpendicular to the base plate 10 to be no less than the length of the second connector 42 facilitates the insertion of the second connector 42 into the second connecting hole 30b. Since both the first connector 41 and the second connector 42 can be inserted downwards from above the base plate 10, operation is relatively convenient.

[0053] In some other possible implementations, the first connector 41 and the second connector 42 can also be inserted from the bottom of the base plate 10. In this way, the first opening 20a only needs to be able to accommodate the nut connected to the first connector 41, and similarly, the second opening 30a only needs to be able to accommodate the nut connected to the second connector 42.

[0054] like Figure 3 As shown, the first wall panel 20 has multiple third connecting holes 20c distributed along its height, and a third connector 43 is inserted into each of the third connecting holes 20c. The third connector 43 is connected to the support plate 30.

[0055] For example, the third connector 43 can be a screw.

[0056] Multiple third connectors 43 are arranged along the height of the first wall panel 20 to fix the support plate 30 to the first wall panel 20, which can improve the stability of the rigid frame. The third connectors 43 are connected by the third connecting hole 20c, which facilitates assembly after the first wall panel 20 and the support plate 30 are manufactured separately.

[0057] like Figure 1 As shown, the rigid frame also includes a second wall panel 50 and multiple wall panel support frames 60. The second wall panel 50 is located on the side of the first wall panel 20 away from the support plate 30. The second wall panel 50 is arranged parallel to and opposite to the first wall panel 20 and is connected to the base plate 10.

[0058] Multiple wall panel support frames 60 are located between the first wall panel 20 and the second wall panel 50, and the wall panel support frames 60 are respectively connected to the first wall panel 20 and the second wall panel 50.

[0059] A second wall panel 50 is arranged parallel to and opposite to the first wall panel 20. A roller can be arranged between the first wall panel 20 and the second wall panel 50, and the first wall panel 20 and the second wall panel 50 support both ends of the roller. A wall panel support frame 60 is connected between the first wall panel 20 and the second wall panel 50, which can play a reinforcing role, improve the stability of the first wall panel 20 and the second wall panel 50, and prevent relative deformation of the first wall panel 20 and the second wall panel 50.

[0060] For example, the second wall panel 50 can be arranged at the edge of the base plate 10, and the first wall panel 20 can be arranged at the middle of the base plate 10, so that other structures can be arranged on the side of the first wall panel 20 away from the second wall panel 50.

[0061] Figure 4 This is a rear view of a rigid frame provided in an embodiment of this application, such as... Figure 4 As shown, the second wall panel 50 has multiple third openings 50a, and the third openings 50a near the bottom plate 10 have fourth connecting holes 50b extending to the bottom plate 10. (Refer to...) Figure 3 As shown, a fourth connector 44 is inserted into the fourth connecting hole 50b, and the fourth connector 44 is connected to the base plate 10. For ease of demonstration of some structures, Figure 4 Some features have been omitted, for example, to facilitate the demonstration of the fourth connecting hole 50b. Figure 4 The fourth connector 44 is omitted.

[0062] For example, the fourth connector 44 can be a screw.

[0063] The second wall panel 50 is connected to the base plate 10 in the same way as the first wall panel 20. After the first wall panel 20, the second wall panel 50 and the base plate 10 are prefabricated, they are assembled. The manufacturing is convenient and the connection strength is high. The first connector 41 and the fourth connector 44 do not occupy space and do not affect the layout of other structures.

[0064] like Figure 2 As shown, the first wall panel 20 also has a plurality of fifth connecting holes 20d, in which fifth connectors are inserted and connected to the wall panel support frame 60.

[0065] like Figure 4 As shown, the second wall panel 50 also has a plurality of sixth connecting holes 50c, in which a sixth connector is inserted, and the sixth connector is connected to the wall panel support frame 60.

[0066] For example, the fifth and sixth connectors can be screws, such as drive screws.

[0067] The wall panel support frame 60 is connected to the first wall panel 20 and the second wall panel 50 via a fifth connector and a sixth connector, respectively. This allows the wall panel support frame 60, the first wall panel 20, and the second wall panel 50 to be processed separately before assembly, facilitating the fabrication of the rigid frame. During the design phase, for different models of rigid frames, the arrangement of the wall panel support frame 60 can be changed simply by adjusting the positions of the fifth connecting hole 20d and the sixth connecting hole 50c, thus meeting the arrangement requirements of different machine heads 200.

[0068] like Figure 1 As shown, the rigid frame also includes a connecting block 70, which is located on the side of the second wall panel 50 closest to the first wall panel 20. The connecting block 70 is connected to the second wall panel 50 and the base plate 10, respectively.

[0069] By arranging a connecting block 70 at the connection between the second wall panel 50 and the base plate 10, the second wall panel 50 and the base plate 10 are further connected through the connecting block 70, which can further improve the stability of the connection between the first wall panel 20 and the base plate 10.

[0070] In this example, the connecting block 70 may have multiple seventh connecting holes 70a, such as Figure 3 As shown, a seventh connector 47 is inserted into the seventh connecting hole 70a, and the seventh connector 47 is connected to the base plate 10.

[0071] The connecting block 70 is connected to the base plate 10 through the seventh connector 47, which facilitates assembly after processing.

[0072] As an example, the connecting block 70 may have multiple eighth connecting holes 70b, into which an eighth connector is inserted, and the eighth connector is connected to the second wall plate 50. The connecting block 70 and the second wall plate 50 are two independent structures, which can be manufactured separately and then connected by the eighth connector.

[0073] For example, the seventh connector 47 and the eighth connector can be screws.

[0074] In some other possible implementations, the connecting block 70 can be an integral structure with the second wall panel 50, or it can be welded to the second wall panel 50.

[0075] In some examples, the base plate 10, the first wall plate 20, and the support plate 30 are all castings. The second wall plate 50 and the wall plate support frame 60 can also be castings. Castings have the advantages of high precision, high manufacturing efficiency, and low cost, which is beneficial for improving the precision of rigid frames.

[0076] Figure 5 This is a schematic diagram of the structure of a printing device provided in an embodiment of this application, such as... Figure 5 As shown, the printing equipment may include a print head 200 and a rigid frame 100, with the print head 200 connected to the rigid frame 100. The rigid frame 100 may be any of the aforementioned types. The print head 200 and the rigid frame 100 may be detachably connected to facilitate the replacement of the print head 200. The print head 200 may be, for example, a flexographic print head or a die-cutting print head.

[0077] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
