[0038] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.
[0039] First, see Figure 1 The embodiment of the present application provides a platen assembly 100, which includes a bracket 1 and a platen 2, wherein the platen 2 is disposed on a side of the bracket 1 facing a first direction X. The dotted arrow in the accompanying drawings refers to an arrow pointing into the paper. The platen 2 is used to carry a printing medium, such as cloth, which includes cloth pieces or ready-made clothes, and the cloth usually has different shapes and sizes. In order to adapt to the cloth, the platen 2 also includes a plurality of models, and different models of platens 2 have different shapes and / or sizes to adapt to cloths of different shapes and / or sizes.
[0040] In the prior art, the table 2 is usually fixed to the bracket 1 by multiple screws. Each time the table 2 is replaced, each screw needs to be disassembled and assembled once, which makes the replacement process of the table 2 not only cumbersome, but also takes a lot of time, and the efficiency of replacing the table 2 is low. To improve this problem, in some embodiments, refer to Figures 2 to 4 As shown, a positioning hole 111 and a first magnetic member 12 are provided on the side of the bracket 1 facing the first direction X; a positioning column 21 and a second magnetic member 22 are provided on the side of the table 2 facing the bracket 1, the positioning column 21 is passed through the positioning hole 111, and the second magnetic member 22 is magnetically connected to the first magnetic member 12. The table 2 is magnetically attracted to the bracket 1 by the first magnetic member 12 and the second magnetic member 22, and the position of the table 2 relative to the bracket 1 is positioned by the positioning column 21 and the positioning hole 111, so that the table 2 is detachably mounted on the bracket 1, which is conducive to simplifying the replacement steps of the table 2 and improving the efficiency of replacing the table 2. Optionally, the positioning column 21 is a metal cylinder, such as a steel cylinder, a cast iron cylinder, etc., which is mounted on the body of the table 2 by screws.
[0041] Among them, one of the first magnetic attraction member 12 and the second magnetic attraction member 22 is a permanent magnet, such as magnetic steel, magnet, neodymium magnet, etc.; the other of the first magnetic attraction member 12 and the second magnetic attraction member 22 is a ferromagnetic metal, such as iron, cobalt, nickel and gadolinium, so that the first magnetic attraction member 12 and the second magnetic attraction member 22 can be magnetically attracted to each other. In some other embodiments, one of the table 2 and the bracket 1 is made of ferromagnetic metal material, and the other is provided with a permanent magnet or is made of permanent magnet material, so that the table 2 can be magnetically attracted to the bracket 1. Optionally, the second magnetic attraction member is a ferromagnetic metal and is mounted on the body of the table 2 by screws.
[0042] For the above-mentioned bracket 1, in some embodiments, see Figure 2 and Figure 4 The bracket 1 includes a support plate 11, and the support plate 11 is in the shape of a plate. A positioning hole 111 is provided on the support plate 11, for example, the positioning hole 111 is formed on the support plate 11. The first magnetic member 12 is provided on the support plate 11, and the first magnetic member 12 can be directly provided on the support plate 11, for example, embedded in the support plate 11 or pasted on the support plate 11, or indirectly provided on the support plate 11 through other components. For example, in some embodiments, the bracket 1 also includes a plurality of threaded columns 13, and the support plate 11 is provided with a plurality of threaded holes 112 along the first direction X, and the threaded columns 13 are threadedly connected with the threaded holes 112, and the first magnetic member 12 is provided at one end of the threaded column 13 facing the first direction X. Among them, the support plate 11 is provided with a plurality of threaded holes 112 along the first direction X, which means that the axis of the threaded hole 112 is parallel to the first direction X, and the number of the threaded holes 112 is multiple. The plurality of threaded holes 112 can be arranged in a spaced-apart manner along a direction perpendicular to the first direction X, for example, in a matrix along the second direction Y and the third direction Z, so that the table 2 and the bracket 1 are magnetically attracted through a plurality of magnetic attraction sites, which is beneficial to increase the magnetic attraction force of the table 2 to the bracket 1, thereby increasing the stability of the table 2 to the bracket 1. The first direction X, the second direction Y and the third direction Z are perpendicular to each other. Optionally, the threaded column 13 is a screw. It is understandable that in some other embodiments, the direction in which the plurality of threaded holes 112 are arranged in a spaced-apart manner can be adaptively adjusted in a direction perpendicular to the first direction X.
[0043] In this embodiment, the length of the threaded column 13 extending out of the support plate 11 along the first direction X can be adjusted by rotating the threaded column 13. If the threaded columns 13 are rotated synchronously, the position of the table 2 relative to the support plate 11 along the first direction X can be adjusted; if the threaded columns 13 are rotated asynchronously, the angle of the table 2 relative to the support plate 11 can be adjusted. For example, when the support plate 11 is set horizontally, the horizontality of the table 2 can be adjusted.
[0044] For the above-mentioned threaded column 13, in some embodiments, see Figure 2The end surface of the threaded column 13 facing the first direction X is provided with a mounting groove 131, and the first magnetic member 12 is provided in the mounting groove 131. The first magnetic member 12 is embedded in the mounting groove 131, and glue can be poured to increase the mounting strength of the first magnetic member 12 in the mounting groove 131. By setting the first magnetic member 12 in the mounting groove 131, and the mounting groove 131 is located at the end face of the threaded column 13 facing the first direction X, the distance between the first magnetic member 12 and the second magnetic member 22 is shortened, and the two can also be in direct contact, which is beneficial to increase the magnetic attraction of the table 2 to the bracket 1, and then increase the stability of the table 2 to the bracket 1; and the first magnetic member 12 is set in the mounting groove 131, which can protect the first magnetic member 12. For example, along the first direction X, the end face of the threaded column 13 is flush with the first magnetic member 12. When the table 2 is placed on the bracket 1, the end face of the threaded column 13 can withstand part of the impact force of the table 2, which is beneficial to improve the problem of damage to the first magnetic member 12. Optionally, along the first direction X, the distance between the first magnetic member 12 and the end face of the threaded column 13 is 1 to 3 mm.
[0045] In some embodiments, there are multiple positioning holes 111, which are arranged at intervals along a direction perpendicular to the first direction X; there are multiple positioning posts 21, and one positioning post 21 is correspondingly provided in one positioning hole 111. Multiple positioning holes 111 are arranged at intervals along a direction perpendicular to the first direction X, for example, they are arranged in a matrix along the second direction Y and the third direction Z, so that the table 2 and the bracket 1 are positioned by multiple positioning posts 21 and positioning holes 111, which is conducive to improving positioning accuracy. Optionally, please refer to Figures 2 to 4 The number of the positioning holes 111 and the number of the positioning posts 21 are both two, and the two positioning holes 111 and the two positioning posts 21 are arranged at intervals along the second direction Y.
[0046] In some embodiments, see 2 and Figure 4 The bracket 1 further includes a movable member 14, which is movably disposed on the support plate 11, and is used to abut against the positioning column 21, so as to cooperate with the inner wall of the positioning hole 111 to clamp the positioning column 21. The movable member 14 is used to move in a direction perpendicular to the first direction X or rotate around an axial direction parallel to the first direction X, so that when observed along the first direction X, at least part of the projection of the movable member 14 can overlap with the projection of the positioning hole 111, and then the movable member 14 abuts against the positioning hole 111 in a direction perpendicular to the first direction X, so as to cooperate with the inner wall of the positioning hole 111 to clamp the positioning column 21, thereby increasing the installation strength of the table 2 installed on the bracket 1.
[0047] It is worth mentioning that when the movable member 14 abuts against the positioning column 21, the positioning column 21 can be pushed to abut against the inner wall of the positioning hole 111, thereby increasing the positioning accuracy between the table 2 and the bracket 1 along the direction perpendicular to the first direction X. Next, an example is given in which the number of the positioning columns 21 and the positioning holes 111 are both two, and the two positioning holes 111 and the two positioning columns 21 are arranged at intervals along the second direction Y. Specifically, the positioning hole 111 includes a first positioning hole 111a and a second positioning hole 111b arranged along the second direction Y, and the positioning column 21 includes a first positioning column 21a and a second positioning column 21b arranged along the second direction Y, the first positioning column 21a is penetrated in the first positioning hole 111a, and the second positioning column 21b is penetrated in the second positioning hole 111b.
[0048] In some embodiments, see Figure 4 The movable member 14 is used to abut against the second positioning column 21b in the opposite direction of the second direction Y, so as to position the table 2 relative to the bracket 1 in the second direction Y. When the movable member 14 applies a force in the opposite direction of the second direction Y to the second positioning column 21b, the first positioning column 21a abuts against the inner wall of the first positioning hole 111a, thereby positioning the relative position of the first positioning column 21a and the bracket 1 in the second direction Y, thereby increasing the positioning accuracy between the table 2 and the bracket 1 in the second direction Y.
[0049] In some embodiments, see Figure 4 , the inner wall of the first positioning hole 111a includes a first surface 111a1 and a second surface 111a2, the first surface 111a1 and the second surface 111a2 are arranged relatively to each other along the third direction Z, and the first surface 111a1 and the second surface 111a2 are both arranged to be inclined toward the second direction Y. The first surface 111a1 is arranged to be inclined toward the second direction Y, which means that the normal direction of the first surface 111a1 rotates in a direction in which the angle between the normal direction and the second direction Y is reduced on the basis of being parallel to the third direction Z. In other words, the angle between the normal direction of the first surface 111a1 and the second direction Y is an acute angle. Similarly, the angle between the normal direction of the second surface 111a2 and the second direction Y is an acute angle. The first surface 111a1 and the second surface 111a2 are arranged relatively to each other, so along the second direction Y, the distance between the first surface 111a1 and the second surface 111a2 gradually increases. In this embodiment, when the movable member 14 abuts against the second positioning column 21b in the opposite direction of the second direction Y, the first surface 111a1 and the second surface 111a2 are in contact with the first positioning column 21a, so that along the third direction Z, the position of the first positioning column 21a is limited by the first surface 111a1 and the second surface 111a2, that is, through the above method, the position of the first positioning column 21a relative to the bracket 1 along the third direction Z is positioned, thereby increasing the positioning accuracy between the first positioning column 21a and the bracket 1 along the third direction Z.
[0050] In some embodiments, see Figure 4 , the movable member 14 includes a third surface 141, and the inner wall of the second positioning hole 111b includes a fourth surface 111b1. The third surface 141 and the fourth surface 111b1 are arranged relatively to each other along the third direction Z, and the third surface 141 is arranged obliquely in the opposite direction of the second direction Y, and the fourth surface 111b1 is perpendicular to the third direction Z. The third surface 141 is arranged obliquely in the opposite direction of the second direction Y, which means that the normal direction of the third surface 141 rotates in the direction in which the angle between the normal direction and the second direction Y increases on the basis of being parallel to the third direction Z. In other words, the angle between the normal direction of the third surface 141 and the second direction Y is an obtuse angle. The third surface 141 and the fourth surface 111b1 are arranged relatively to each other, so along the second direction Y, the distance between the third surface 141 and the fourth surface 111b1 gradually decreases. In this embodiment, when the movable member 14 abuts against the second positioning column 21b in the opposite direction of the second direction Y, the third surface 141 and the fourth surface 111b1 are in contact with the second positioning column 21b, so that along the third direction Z, the position of the second positioning column 21b is limited by the third surface 141 and the fourth surface 111b1, that is, through the above method, the position of the second positioning column 21b relative to the bracket 1 along the third direction Z is positioned, thereby increasing the positioning accuracy between the second positioning column 21b and the bracket 1 along the third direction Z.
[0051] By means of the above method, the positioning accuracy between the first positioning column 21 a and the second positioning column 21 b and the bracket 1 along the third direction Z can be increased, thereby increasing the positioning accuracy between the table plate 2 and the bracket 1 along the third direction Z.
[0052] In particular, the fourth surface 111b1 is perpendicular to the third direction Z, so when the fourth surface 111b1 contacts the second positioning column 21b, the position of the second positioning column 21b relative to the bracket 1 along the third direction Z can be positioned. In this way, when the movable member 14 applies a force in the opposite direction of the second direction Y to the second positioning column 21b, and the table 2 moves relative to the bracket 1 in the opposite direction of the second direction Y, the positioning between the second positioning column 21b and the bracket 1 along the third direction Z will not be affected.
[0053] In some embodiments, see Figure 2 and Figure 4 The middle of the support plate 11 is provided with a through opening 113, thereby reducing the mass of the support plate 11. In addition, along the second direction Y, both sides of the opening 113 are connected to the first positioning hole 111a and the second positioning hole 111b, respectively, thereby further reducing the mass of the support plate 11 without affecting the functions of the first positioning hole 111a and the second positioning hole 111b.
[0054] For the above movable part 14, see Figure 4The movable member 14 is provided with a sliding hole 142, the sliding hole 142 penetrates the movable member 14 along the first direction X, and the sliding hole 142 extends along the second direction Y. A fastener (not shown) is passed through the sliding hole 142 and connected to the support plate 11, so that the movable member 14 can be slidably arranged on the support plate 11 along the second direction Y. Among them, when the sliding hole 142 extends toward the second direction Y, it also extends toward the opposite direction of the third direction Z. Therefore, when the movable member 14 slides relative to the support plate 11 along the opposite direction of the second direction Y, it also slides relative to the support plate 11 along the third direction Z, and a force toward the fourth surface 111b1 can be applied to the second positioning column 21b, thereby improving the problem that the second positioning column 21b does not contact the fourth surface 111b1.
[0055] In some embodiments, see Figure 2 and Figure 4 The bracket 1 also includes an elastic member 15, one end of which is connected to the support plate 11, and the other end of which is connected to the movable member 14. The elastic member 15 is used to apply an elastic force to the movable member 14 in the opposite direction of the second direction Y. The elastic member 15 can apply a tensile force, such as a tension spring. One end of the elastic member 15 facing the second direction Y is connected to the movable member 14, and the other end of the tension spring is connected to the middle of the support plate 11, thereby applying an elastic force to the movable member 14 in the opposite direction of the second direction Y. The bracket 1 also includes a connecting beam 16, which extends along the third direction Z. The connecting beam 16 is disposed at the opening 113, and both ends of the connecting beam 16 are connected to the support plate 11, while the other end of the tension spring is connected to the connecting beam 16, thereby realizing that the other end of the tension spring is connected to the middle of the support plate 11.
[0056] In a second aspect, an embodiment of the present application provides a printer (not shown), the printer comprising a platen assembly 100 as described above. The printer has the structural features and beneficial effects of the platen assembly 100, which will not be described in detail here. The printer can be a flatbed printer, such as a UV printer (Ultraviolet LED Inkjet Printer), to print on printing media such as clothing and fabrics.
[0057] In the table assembly 100 and the printer of the embodiment of the present application, the positioning column 21 of the table 2 is inserted into the positioning hole 111 to position the table 2, and the table 2 is magnetically connected to the bracket 1, so that the table 2 can be detachably mounted on the bracket 1, which is conducive to simplifying the replacement steps of the table 2 and improving the efficiency of replacing the table 2. The movable member 14 can cooperate with the inner wall of the positioning hole 111 to clamp the positioning column 21, thereby increasing the installation strength of the table 2 on the bracket 1. The movable member 14 can apply a force in the opposite direction of the second direction Y to the second positioning column 21b, so that the first positioning column 21a is against the inner wall of the first positioning hole 111a, thereby increasing the positioning accuracy between the table 2 and the bracket 1 along the second direction Y. The inner wall of the first positioning hole 111a includes a first surface 111a1 and a second surface 111a2, thereby increasing the positioning accuracy between the first positioning column 21a and the bracket 1 along the third direction Z. The movable member 14 includes a third surface 141 , and the inner wall of the second positioning hole 111 b includes a fourth surface 111 b 1 , which increases the positioning accuracy along the third direction Z between the second positioning column 21 b and the bracket 1 .
