In order to be applicable to printing substrates of different lengths, the printing platform further comprises a limiting block and a spring, the limiting block is slidably connected in the placing groove, and the spring is arranged between the limiting block and the printing platform to drive the limiting block to abut against the printing substrate of different lengths, so that the printing substrate is limited by the limiting block and the printing platform.

[0004] However, when the printing substrate needs to be placed and taken out, the limiting block needs to be pressed for operation, which is troublesome, and therefore needs to be improved. SUMMARY

[0005] In order to facilitate the placing and taking out of the printing substrate, in a first aspect, the present application provides a printing platform.

[0006] The printing platform provided by the present application adopts the following technical scheme:

[0007] A printing platform comprises a placing plate, a guide rail and a limiting assembly; a placing groove is formed in one side of the placing plate along the length direction of the placing plate; the guide rail is arranged on the side of the placing plate away from the placing groove and is arranged along the width direction of the placing plate, and one side of the guide rail is provided with an inclined guide surface; the limiting assembly comprises a limiting block and a plurality of first elastic members; the limiting block is slidably connected to the placing groove along the length direction of the placing plate and extends to the outside of the placing plate on the side close to the guide rail; and the plurality of first elastic members are arranged between the side of the limiting block away from the guide rail and the placing plate to drive the limiting block to abut against the guide surface.

[0008] By adopting the above technical scheme, in actual application, in the initial state, when the placing plate is located at one end of the guide rail, the limiting block abuts against the guide surface on the side close to the guide rail under the driving action of the plurality of first elastic members, at this time, the placing space of the placing groove is large, so as to facilitate the direct placing of the printing substrate in the placing groove;

[0009] After the placement of the printing material is completed, the driving device drives the placement plate to move along the length direction of the guide rail to the printing device. Due to the inclined arrangement of the guide surface, the limiting block gradually moves towards the printing material, which can stably drive the printing material to move, so that the printing material is limited between the limiting block and the placement plate, thereby achieving the limiting and fixing of the printing material. In this process, the side of the printing material does not need to be abutted to the placement groove, which is convenient for placing the printing material and can stably limit the printing material.

[0010] After the printing of the printing material is completed, the driving device drives the placement plate to reset to the initial state, and the limiting block releases the limiting of the printing material. At this time, the placement space is larger, thereby facilitating the taking out of the printing material.

[0011] Preferably, the side of the limiting block close to the guide rail is provided with a connecting surface, and the connecting surface is in close contact with the guide surface.

[0016] By adopting the above technical scheme, the mounting blocks and the second elastic members are arranged. The mounting blocks provide a mounting basis for the rotation of the rollers. When the limiting block abuts against the roller, the mounting block compresses the second elastic member, so that the roller extends into the sliding groove, thereby ensuring that the limiting block stably abuts against the guide surface.

[0017] Preferably, the printing platform further comprises an ejection assembly, and the ejection assembly comprises an ejection rod. The placement plate is vertically provided with a movable slot in communication with the placement groove. The ejection rod is movably arranged in the movable slot, and one end of the ejection rod is arranged in the movable slot, and the other end of the ejection rod abuts against one end of the guide rail away from the guide surface.

[0020] By adopting the technical scheme, when one end of the ejection rod is located in the first groove part and the other end is located in the movable groove, when one end of the ejection rod is located in the second groove part and moves away from one end of the first groove part, the ejection rod gradually protrudes from the movable groove to slowly eject the printing object.

[0021] Preferably, the movable groove is located on one side of one long side of the placement groove.

[0022] By adopting the technical scheme, the movable groove is arranged on the side of the placement groove away from the limiting block, so that the printing object is placed obliquely when the ejection rod ejects the printing object, thereby facilitating taking out of the printing object.

[0023] Preferably, the ejection assembly further comprises an ejection plate, and the ejection plate is arranged at one end of the ejection rod away from the guide rail.

[0024] By adopting the technical scheme, the ejection plate is arranged to increase the contact area with the printing object, thereby improving the stability of the printing object being ejected.

DETAILED DESCRIPTION

[0040] The following will be described in detail in combination with the accompanying Figures 1-6 The present application will be further described in detail.

[0041] The embodiment of the present application discloses a printing platform.

[0042] Embodiment 1:

[0043] With reference to Figure 1 The printing platform comprises a placing plate 1, a guide rail 2 and a limiting assembly 3. The placing plate 1 is in the shape of a rectangular plate. A placing groove 11 for placing a printing object is formed in the upper side of the placing plate 1. The placing groove 11 is in the shape of a rectangle and is arranged along the length direction of the placing plate 1. The placing plate 1 is driven to move along the width direction of the placing plate 1 by a driving device of a screen printing machine.

[0044] The guide rail 2 is arranged on the lower side of the placing plate 1 and between the two end walls of the placing groove 11. The guide rail 2 is in the shape of a rectangular block and is arranged along the width direction of the placing plate 1. A slot is formed in one side of the guide rail 2 to form an inclined guide surface 21. The width of one end of the guide rail 2 is smaller than that of the other end. The guide rail 2 is fixedly connected to the rack of the screen printing machine.

[0045] With reference to Figure 1 and Figure 2 The limiting assembly 3 comprises a limiting block 31 and a plurality of first elastic members 32. The limiting block 31 is in the shape of a rectangular block and is slidably connected to the placing groove 11. The sliding direction of the limiting block 31 is the length direction of the placing plate 1. The lower side of the limiting block 31 protrudes downward to form a limiting column 311. The limiting column 311 extends out of the placing plate 1. Correspondingly, the placing plate 1 is provided with a gap slot 12 at the position of the placing groove 11 for the movement of the limiting column 311. The plurality of first elastic members 32 are arranged between the limiting block 31 and the placing plate 1. Specifically, the first elastic members 32 are springs. In other embodiments, the first elastic members 32 can also be elastic columns. One end of the plurality of first elastic members 32 is fixedly connected to the slot wall of the placing plate 1 at the end of the placing groove 11 close to the guide surface 21. The other end is fixedly connected to the side of the limiting block 31 away from the guide rail 2, so as to drive the limiting column 311 to abut against the guide surface 21, that is, to drive the limiting block 31 to be close to the guide rail 2.

[0046] In actual application, when the printing object is loaded, the placing plate 1 is located at the initial position, that is, the placing plate 1 is located at the end of the guide rail 2 with a larger width. Under the driving action of the plurality of first elastic members 32, the side of the limiting column 311 close to the guide rail 2 abuts against the guide surface 21, so as to limit the movement of the limiting block 31. At this time, the placing space of the placing groove 11 is relatively large (that is, much larger than the space required for placing the printing object), so as to facilitate the direct placement of the printing object in the placing groove 11. Similarly, after the printing of the printing object is completed, the placing plate 1 is reset to the initial position, and has a relatively large movement space, so as to facilitate the taking out of the printing object.

[0047] Wherein, after the placement of the printing object, the placement plate 1 is driven by the driving device to move to the printing device. Due to the inclined arrangement of the guide surface 21, the limiting column 311 moves the limiting block 31 gradually towards the printing object under the guidance of the guide surface 21, which can stably drive the printing object to move, so that the printing object is limited between the limiting block 31 and the placement plate 1, thereby achieving the limiting and fixing of the printing object. The printing object can be stably limited, and the side of the printing object does not need to be abutted to the placement groove 11, which further facilitates the placement of the printing object.

[0048] Referring to Figure 2 and Figure 3 In some embodiments, the limiting column 311 is provided with a connecting surface 312 on one side close to the guide rail 2, and the connecting surface 312 is matched with the guide surface 21, so that the connecting surface 312 is attached to the guide surface 21, effectively increasing the contact area between the limiting column 311 and the guide surface 21, so that the limiting column 311 is stably abutted to the guide surface 21 under the action of the plurality of first elastic members 32, thereby improving the stability of the movement of the limiting block 31, and further improving the stability of the limiting and fixing of the printing object.

[0049] In some embodiments, the printing platform further comprises a rolling assembly 4, and the rolling assembly 4 comprises a plurality of rollers 41, which are all rotationally connected to the guide rail 2 on one side of the guide surface 21 and are uniformly spaced along the length direction of the guide surface 21. Wherein, each roller 41 slightly protrudes from the guide surface 21 to facilitate the relative movement between the limiting column 311 and the guide surface 21.

[0050] In some embodiments, the rolling assembly 4 further comprises a plurality of mounting blocks 42 and a plurality of second elastic members 43, and the number of the rollers 41, the mounting blocks 42 and the second elastic members 43 correspond. Correspondingly, a plurality of sliding grooves 22 are formed on one side of the guide rail 2, each mounting block 42 is slidingly connected in each sliding groove 22, and each second elastic member 43 is also a spring. One end of each second elastic member 43 is fixedly connected to the mounting block 42, and the other end is fixedly connected to the guide rail 2 at the bottom wall of the sliding groove 22, so as to drive the mounting block 42 to move towards the opening end of the sliding groove 22, and each roller 41 is rotationally connected to each mounting block 42, so that the roller 41 protrudes from the guide surface 21. Wherein, the force of the plurality of first elastic members 32 driving the limiting block 31 is greater than the force of the second elastic member 43 driving the mounting block 42, so that when the limiting column 311 abuts against the roller 41, the mounting block 42 moves into the sliding groove 22, so that the roller 41 extends into the sliding groove 22, and the connecting surface 312 is attached to the guide surface 21, thereby ensuring the stability of the movement of the limiting block 31.

[0051] Referring to Figure 1 and Figure 4In some embodiments, the printing platform further comprises an ejection assembly 5, the ejection assembly 5 comprises an ejection rod 51, the ejection rod 51 is a cylindrical rod, the placement plate 1 is provided with a movable slot 13 in the vertical direction, the upper end of the movable slot 13 is communicated with the placement slot 11, the ejection rod 51 is movably arranged in the movable slot 13, specifically, the upper end of the ejection rod 51 is located in the movable slot 13, and the lower end of the ejection rod 51 abuts against the guide rail 2.

[0052] In the embodiment, the upper side of the guide rail 2 is provided with a guide slot 23 along the length direction of the guide rail 2, the lower end of the ejection rod 51 is slidably connected to the guide slot 23 and abuts against the bottom wall of the guide slot 23 of the guide rail 2. Specifically, the guide slot 23 comprises a first slot portion 231 and a second slot portion 232, one end of the first slot portion 231 extends to the end of the guide rail 2 with smaller width, the other end of the first slot portion 231 is communicated with one end of the second slot portion 232, and the other end of the second slot portion 232 away from the first slot portion 231 extends to the end of the guide rail 2 with larger width and the slot depth gradually decreases.

[0053] When the ejection rod 51 slides in the first slot portion 231, the upper end of the ejection rod 51 is flush with the bottom surface of the placement slot 11, and the placement plate 1 is in the initial position, the lower end of the ejection rod 51 is located at one end of the first slot portion 231 close to the second slot portion 232, because the upper end of the ejection rod 51 is flush with the bottom surface of the placement slot 11, the printing object can be placed in the placement slot 11 flatly. When the ejection rod 51 slides in the second slot portion 232 away from the one end of the first slot portion 231, the ejection rod 51 gradually moves upward, so that the ejection rod 51 protrudes in the movable slot 13, so that when the ejection rod 51 abuts against the end of the guide rail 2 away from the guide surface 21, the other end of the ejection rod 51 protrudes in the movable slot 13, the printing object can be slowly ejected from the placement slot 11, so as to be taken out stably. It should be noted that after the printing object is printed, the driving device drives the placement plate 1 to move to the end of the guide rail 2, that is, the ejection rod 51 moves to the second slot portion 232, and after the printing object is taken out, the driving device drives the placement plate 1 to the initial position.

[0054] In some embodiments, the movable slot 13 is located in the placement slot 11 and on one side of one long side of the placement slot 11, so that when the ejection rod 51 ejects the printing object, the printing object is placed obliquely, thereby facilitating the taking out of the printing object.

[0055] The implementation principle of the embodiment is that in actual application, when the printing substrate is fed, the placing plate 1 is located at the initial position, that is, the placing plate 1 is located at one end of the guide rail 2 with a larger width, and under the driving action of the plurality of first elastic members 32, the limiting column 311 abuts against the guide surface 21 on one side of the guide rail 2 to limit the movement of the limiting block 31, at this time, the placing space of the placing groove 11 is larger, so as to facilitate the direct placing of the printing substrate in the placing groove 11, and in the same way, after the printing of the printing substrate is completed, the placing plate 1 is reset to the initial position, and has a larger movement space, thereby facilitating the taking out of the printing substrate.

[0056] In the embodiment, after the placing of the printing substrate is completed, the placing plate 1 is moved to the printing device under the driving of the driving device, and since the guide surface 21 is inclined, the limiting block 31 is gradually moved towards the printing substrate under the guiding action of the guide surface 21, can stably drive the movement of the printing substrate, and limits the printing substrate between the limiting block 31 and the placing plate 1 to realize the limiting and fixing of the printing substrate, can stably limit the printing substrate, and without abutting one side of the printing substrate against the placing groove 11, further facilitates the placing of the printing substrate.

[0057] Embodiment 2

[0058] With reference to Figure 5 The embodiment is the same as the other structures of the embodiment 1, and the difference lies in that the position of the movable groove 13 is located at the middle position of the placing groove 11, and the ejection assembly 5 further comprises an ejection plate 52, the ejection plate 52 is in the shape of a rectangular plate and is arranged at the upper end of the ejection rod 51, so that the ejection plate 52 abuts against the printing substrate to increase the contact area with the printing substrate, thereby improving the stability of the ejection of the printing substrate.

[0059] In some embodiments, the ejection plate 52 is screw-connected to the ejection rod 51, the distance between the ejection plate 52 and the ejection rod 51 is adjusted by rotating the ejection rod 51, the ejection plate 52 is moved upwards to adjust the distance between the ejection plate 52 and the upper side of the placing plate 1, and the printing substrate is placed on the ejection plate 52, so that the printing platform can be suitable for printing substrates with different thicknesses, thereby improving the applicability of the printing platform.

[0060] The embodiment of the application further discloses a screen printing machine.

[0061] With reference to Figure 6The screen printing machine comprises a frame 6, driving devices 7, printing devices 8 and the printing platform as described above, and the driving devices 7 and the printing devices 8 are fixedly connected to the frame 6. Specifically, the placement plate 1 is located at the middle position of the driving devices 7, the driving devices 7 drive the placement plate 1 to move along the width direction of the driving devices 7 to the lower side of the printing devices 8, so that the printing devices 8 print the printing object on the placement plate 1, and the guide rails 2 are fixedly connected to the frame 6 and located between the driving devices 7.
