Description

Technical Field

[0001] This utility model relates to the field of printing platform technology, and in particular to a sign production printing platform. Background Technology

[0002] As the name suggests, signs are directional signs used for identification. They are printed with text and images to indicate information and provide warnings. Common types of signs include traffic signs, metal signs, electrical appliance signs, directional signs, trademark signs, copper and aluminum nameplates, and advertising signs.

[0003] Chinese utility model patent CN215850342U discloses a printing platform for sign production, including a processing table, a UV printer, an inclined plate, and a fixing plate. The UV printer is installed on the processing table, and the processing table has a drop opening. A conveyor belt is provided on one side of the top of the drop opening. An inclined plate is welded between the side walls of the drop opening. The bottom of the inclined plate is connected to the fixing plate through a support plate. A groove is provided on the fixing plate, and the bottom end of the inclined plate is located in the groove.

[0004] In order to ensure the printing effect of existing sign production printing platforms, workers need to visually align the signs and place them on the conveyor belt surface. However, this method of relying solely on visual observation has a large error, which increases the probability of printing misalignment and thus cannot guarantee the printing effect of the signs. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a sign production and printing platform.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a sign production and printing platform, including a mounting base and a belt conveyor fixed to the top of the mounting base. A positioning shell is fixed to the top of the conveyor belt of the belt conveyor. Four sliding plates arranged in a circular array are slidably disposed on the positioning shell. The included angle between two adjacent sliding plates is 90 degrees. A centering clamp is fixed on the sliding plate. The number of centering clamps is equal to the number of sliding plates and their positions correspond one-to-one. A displacement mechanism is provided on the positioning shell for driving the four sliding plates to move closer or further apart from each other.

[0007] By adopting the above technical solution, the staff first places the sign on top of the positioning shell, between the four centering clamps. Then, the displacement mechanism drives the four sliding plates to move closer to each other, which in turn moves the centering clamps connected to the sliding plates until the four centering clamps are in contact with the surface of the sign, thus achieving the centering and alignment of the sign. Finally, the belt conveyor moves the sign to the printer for printing. There is no need for manual alignment of the sign by eye, which reduces the probability of printing misalignment and ensures the printing effect of the sign. In addition, the positioning of the sign by the four centering clamps improves the stability of the sign during printing.

[0008] Furthermore, the positioning shell has an internally hollow structure, and the displacement mechanism includes a displacement component. The displacement component includes a connecting plate that passes through the positioning shell and slides with it, an adjusting column that is disposed on the connecting plate, and an adjusting disk that is rotatably disposed inside the positioning shell. The adjusting disk has an adjusting through hole that is eccentrically disposed with it, and the adjusting column passes through the adjusting through hole and slides with it. The number of connecting plates, adjusting columns, adjusting through holes, and sliding plates are all equal and their positions correspond one-to-one. The displacement mechanism also includes a rotating component for driving the adjusting disk to rotate and a connecting component for connecting the sliding plate and the connecting plate.

[0009] By adopting the above technical solution, the rotating component drives the adjusting plate to rotate after it works. Due to the sliding fit between the adjusting through hole and the adjusting column, and the eccentric setting between the adjusting through hole and the adjusting plate, the adjusting column, the connecting plate connected to the adjusting column, the sliding plate connected to the connecting plate through the connecting component, and the centering clamping plate all move closer to or further away from each other, so as to ensure that the device can properly clamp or release the nameplate.

[0010] Furthermore, the rotating assembly includes a connecting column rotatably mounted on the bottom wall of the positioning housing, a gear fixedly sleeved on the connecting column, and a rack that passes through the positioning housing and slides in cooperation with the positioning housing. The adjusting disc is fixedly sleeved on the connecting column, and the rack meshes with the gear. The displacement mechanism also includes a moving component for driving the rack to move.

[0011] By adopting the above technical solution, the moving component drives the rack to move after it works, which in turn drives the gear meshing with the rack and the connecting column fixed to the gear to rotate, thereby ensuring the normal rotation of the adjusting plate.

[0012] Furthermore, the moving component includes a rotating column rotatably mounted on a rack and an adjusting plate fixed to the frame of the belt conveyor. The adjusting plate has a through-hole for displacement, which includes an inclined section and a horizontal section. The rotating column passes through the inclined section of the displacement through-hole and slides into it.

[0013] By adopting the above technical solution, as the positioning shell moves towards the printer, it drives the rack connected to the positioning shell and the rotating column connected to the rack to move as well. The rotating column first moves from the inclined section of the displacement through hole to the horizontal section of the displacement through hole. During this process, the rotating column drives the rack to move towards the interior of the positioning shell. The rack drives the gear, connecting column, and adjusting disc to rotate. Under the action of the displacement component, the sliding plate and the centering clamping plate move towards the axis of the adjusting disc until the label is clamped. Finally, the rotating column moves along the horizontal section of the displacement through hole until the positioning shell moves to below the printer. During this process, the centering clamping plate remains in contact with the label, achieving the purpose of clamping the label as the positioning shell moves. Similarly, as the positioning shell moves away from the printer, the rotating column moves along the horizontal section of the displacement through hole until it reaches the inclined section of the displacement through hole. Finally, the rotating column moves along the inclined section of the displacement through hole and resets. During this process, the centering clamping plate moves away from the surface of the label and resets, thereby achieving the purpose of automatically releasing the label.

[0014] Furthermore, the connecting assembly includes a threaded post that passes through the sliding plate and is rotatably connected to the sliding plate, and a limiting rod fixed to the sliding plate. The end of the connecting plate away from the axis of the adjusting disc has a threaded hole that is threadedly connected to the threaded post, and the end of the connecting plate away from the axis of the adjusting disc has an insertion hole that is inserted into the limiting rod. The number of connecting assemblies is equal to the number of sliding plates and their positions correspond one-to-one.

[0015] By adopting the above technical solution, during the movement of the connecting plate, the threaded column and the threaded hole are connected, which in turn drives the sliding plate to move, thereby ensuring the normal clamping or loosening of the nameplate by the centering clamp. In addition, by rotating the threaded column, the initial distance between the sliding plate and the connecting plate can be adjusted under the limiting action of the limiting rod and the insertion hole, thereby changing the initial distance between the four sliding plates and the axis of the adjusting disc to adapt to nameplates of various sizes and expand the applicability of the device.

[0016] Furthermore, an L-shaped limiting plate is fixed inside the positioning shell, and a fixing block is fixed on the rack. The horizontal section of the limiting plate passes through the fixing block and slides with the fixing block.

[0017] By adopting the above technical solution, the good limiting effect between the limiting plate and the fixing block improves the stability of the rack movement.

[0018] Furthermore, the adjusting column passes through the connecting plate and is rotatably connected to the connecting plate.

[0019] By adopting the above technical solution, the adjusting column and the connecting plate are rotatably connected, which reduces the friction between the adjusting column and the adjusting through hole when the adjusting column moves.

[0020] Furthermore, the centering clamp has a wavy groove on the side wall near the axis of the adjusting disc.

[0021] By adopting the above technical solution, the wavy groove design improves the friction when the centering plate contacts the sign.

[0022] In summary, this utility model has the following beneficial effects: In this application, by improving the existing technical structure, it is not necessary to manually align the sign with the naked eye, which reduces the probability of printing misalignment and ensures the effect of sign printing.

Detailed Implementation

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] like Figure 1-3As shown in the figure, this application discloses a sign production and printing platform, including a mounting base 1, a belt conveyor 2, a positioning shell 3, and a displacement mechanism 6. The belt conveyor 2 is fixed to the top of the mounting base 1. The positioning shell 3 is fixed to the top of the conveyor belt of the belt conveyor 2. The positioning shell 3 has a hollow internal structure. Four sliding plates 4 arranged in a circular array are slidably disposed on the positioning shell 3. The included angle between two adjacent sliding plates 4 is 90 degrees. Centering clamps 5 are fixed on the sliding plates 4. The number of centering clamps 5 is equal to the number of sliding plates 4, and their positions correspond one-to-one. The staff first places the sign on top of the positioning shell 3, between the four centering clamps 5. Then, the displacement mechanism 6 drives the four sliding plates 4 to move closer to each other, which in turn moves the centering clamps 5 connected to the sliding plates 4 together until the four centering clamps 5 are in contact with the surface of the sign, thus achieving the centering and alignment of the sign. Finally, the belt conveyor 2 moves the sign to the printer for printing. There is no need for manual alignment of the sign by eye, which reduces the probability of printing deviation and ensures the printing effect of the sign. In addition, the positioning of the sign by the four centering clamps 5 improves the stability of the sign during printing.

[0027] A displacement mechanism 6 is mounted on the positioning shell 3. The displacement mechanism 6 drives the four sliding plates 4 to move closer to or further apart from each other. The displacement mechanism 6 includes a displacement component 61, a rotation component 62, a movement component 63, and a connecting component 64. The displacement component 61 includes a connecting plate 611, an adjusting column 612, and an adjusting disc 613. The connecting plate 611 is mounted through the positioning shell 3 and slides in cooperation with it. The adjusting column 612 is mounted on the connecting plate 611 and passes through the adjusting through hole 7, sliding in cooperation with it. The adjusting disc 613 is rotatably mounted inside the positioning shell 3. The adjusting disc 613 has an adjusting through hole 7 that is eccentrically positioned to the adjusting disc 613. The number of connecting plates 611, adjusting columns 612, adjusting through holes 7, and sliding plates 4 are all equal and their positions correspond one-to-one. After the rotating component 62 is working, it drives the adjusting plate 613 to rotate. Since the adjusting through hole 7 and the adjusting column 612 are in sliding fit, the adjusting through hole 7 and the adjusting plate 613 are eccentrically set, which causes the adjusting column 612, the connecting plate 611 connected to the adjusting column 612, the sliding plate 4 connected to the connecting plate 611 through the connecting component 64 and the centering clamping plate 5 to move closer or further away from each other, so as to ensure that the device can properly clamp or release the nameplate.

[0028] The rotating assembly 62 drives the adjusting disk 613 to rotate. The rotating assembly 62 includes a connecting column 621, a gear 622, and a rack 623. The connecting column 621 is rotatably mounted on the inner bottom wall of the positioning housing 3. The adjusting disk 613 is fixedly sleeved on the connecting column 621, and the gear 622 is also fixedly sleeved on the connecting column 621. The rack 623 is inserted through the positioning housing 3 and slides in engagement with it, meshing with the gear 622. After the moving assembly 63 operates, it drives the rack 623 to move, thereby causing the gear 622 meshing with the rack 623 and the connecting column 621 fixed to the gear 622 to rotate, thus ensuring the normal rotation of the adjusting disk 613.

[0029] The moving component 63 is used to drive the rack 623 to move. The moving component 63 includes a rotating column 631 and an adjusting plate 632. The rotating column 631 is rotatably mounted on the rack 623, and the adjusting plate 632 is fixed to the frame of the belt conveyor 2. A displacement through hole 8 is provided through the adjusting plate 632. The displacement through hole 8 includes an inclined section and a horizontal section. The rotating column 631 passes through the inclined section of the displacement through hole 8 and slides in engagement. As the positioning shell 3 moves toward the printer, it drives the rack 623 connected to the positioning shell 3 and the rotating column 631 connected to the rack 623 to move. The rotating column 631 first moves from the inclined section of the displacement through hole 8 to the horizontal section of the displacement through hole 8. During this process, the rotating column 631 drives the rack 623 to move toward the interior of the positioning shell 3. The rack 623 drives the gear 622, the connecting column 621 and the adjusting plate 613 to rotate. Under the action of the displacement component 61, the sliding plate 4 and the centering clamp 5 move toward the axis of the adjusting plate 613 until the label is clamped. Finally, the rotating column 631 moves along the horizontal section of the displacement through hole 8 until the positioning shell 3 moves to the bottom of the printer. During this process, the centering clamp 5 remains in contact with the label. When the positioning shell 3 moves, the purpose of clamping the label is achieved. Similarly, as the positioning shell 3 moves away from the printer, the rotating column 631 moves along the horizontal section of the displacement through hole 8 until the rotating column 631 moves to the inclined section of the displacement through hole 8. Finally, the rotating column 631 moves along the inclined section of the displacement through hole 8 and resets. During this process, the centering clamp 5 moves away from the surface of the label and resets, thereby achieving the purpose of automatically releasing the label.

[0030] The connecting assembly 64 is used to connect the sliding plate 4 to the connecting plate 611. The connecting assembly 64 includes a threaded post 641 and a limiting rod 642. The threaded post 641 passes through the sliding plate 4 and is rotatably connected to the sliding plate 4. The end of the connecting plate 611 away from the axis of the adjusting disk 613 has a threaded hole 9 for threaded connection with the threaded post 641. The limiting rod 642 is fixed to the sliding plate 4. The end of the connecting plate 611 away from the axis of the adjusting disk 613 has an insertion hole 10 for insertion into the limiting rod 642. The number of connecting assemblies 64 is equal to the number of sliding plates 4, and their positions correspond one-to-one. During the movement of the connecting plate 611, the threaded column 641 is threadedly connected to the threaded hole 9, which in turn drives the sliding plate 4 to move, thereby ensuring the normal clamping or loosening of the nameplate by the centering clamp 5. In addition, by rotating the threaded column 641, the initial distance between the sliding plate 4 and the connecting plate 611 can be adjusted under the limiting action of the limiting rod 642 and the insertion hole 10, thereby changing the initial distance between the four sliding plates 4 and the axis of the adjusting plate 613 to accommodate nameplates of various sizes and expand the applicability of the device.

[0031] An L-shaped limiting plate 11 is fixed inside the positioning shell 3, and a fixing block 12 is fixed on the rack 623. The horizontal section of the limiting plate 11 passes through the fixing block 12 and slides in cooperation with the fixing block 12. The good limiting effect between the limiting plate 11 and the fixing block 12 improves the stability of the rack 623 during movement.

[0032] The adjusting column 612 passes through the connecting plate 611 and is rotatably connected to the connecting plate 611. The rotatable connection between the adjusting column 612 and the connecting plate 611 reduces the friction between the adjusting column 612 and the adjusting through hole 7 when the adjusting column 612 moves.

[0033] The centering plate 5 has a wavy groove on its side wall near the axis of the adjusting disc 613. The wavy groove increases the friction between the centering plate 5 and the nameplate.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
