Technical Field
[0001] This utility model relates to the field of printing and positioning technology for standees, specifically a positioning structure for printing standees. Background Technology
[0002] Acrylic is an important, well-developed, and malleable polymer material. Because acrylic is easy to cut, carve, polish, print, bend, bond, grind, and paint, many display stands are made of acrylic. When printing acrylic stands, the printing process generally refers to screen printing, which is a machine that uses a screen printing plate to apply the printing.
[0003] Currently, existing acrylic standees require screen printing to display different patterns. When printing individual standees, some existing screen printing devices lack automated mechanisms to position and fix acrylic standees of different sizes, causing the acrylic standees to easily shift during the printing process. Manual handling of acrylic standees by hand is also not precise enough and has low work efficiency. Therefore, we provide a positioning structure for printed standees to solve this problem. Utility Model Content
[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a positioning structure for printed standees that can solve the aforementioned problems.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A positioning structure for printed standees includes a belt conveyor, a positioning mechanism, and a screen printing machine. The screen printing machine is located in the middle of one side of the belt conveyor, and the positioning mechanism is installed on both sides of the belt conveyor. The belt of the belt conveyor carries a supporting mechanism.
[0007] The bearing mechanism includes a bearing plate, the upper end of which is provided with a bearing groove, and an outer frame is installed on the outer side of the bearing plate. The lower end of the outer frame is attached to the upper end of the positioning mechanism.
[0008] The positioning mechanism includes two sets of fixing bars installed on both sides of the belt conveyor. Each fixing bar has a mounting groove in the middle and a first touch switch in the inner cavity of each mounting groove. Each fixing bar has a first mounting hole and a second mounting hole at its upper end. A first positioning component and a second positioning component are respectively installed in the inner cavity of the first mounting hole and the second mounting hole. A plug-in component is installed on the outer side of the outer frame to be inserted into it.
[0009] As a further embodiment of this utility model: the first positioning component includes a first electromagnet installed in the lower part of the inner cavity of the first mounting hole, a mounting block installed in the inner cavity of the first mounting hole, a support column movably inserted into the middle of the mounting block, a support block connected to the outer side of the support column, a spring connected between the support block and the mounting block, an iron block connected to the lower end of the support column, a stop block connected to the upper end of the support column, and a two-touch switch installed in the middle of the stop block.
[0010] As a further embodiment of this utility model: the second positioning component includes a second electromagnet installed in the lower part of the inner cavity of the second mounting hole, a magnetic block is movably disposed in the inner cavity of the second mounting hole, a fixing sleeve is installed on the outer side of the magnetic block, a connecting post is equidistantly connected to the upper end of the fixing sleeve, and a positioning block is connected to the upper end of the connecting post.
[0011] As a further embodiment of this utility model: the inner cavity of the second mounting hole is symmetrically provided with limiting grooves, and the inner cavity of each limiting groove is movably provided with a limiting block, and each limiting block is integrally connected with the fixing sleeve.
[0012] As a further embodiment of this utility model: the plug-in assembly includes a first fixing block installed on both sides of the outer frame, and the outer side of the first fixing block is provided with a positioning groove that plugs into the stop block.
[0013] As a further embodiment of this utility model: the plug-in assembly further includes a second fixing block installed on both sides of the outer frame, and the lower end of the second fixing block is provided with a positioning hole for plugging into the positioning block.
[0014] As a further embodiment of this utility model: support sleeves are installed around the lower end of the outer frame, and the lower part of the inner cavity of each support sleeve is movably connected to a ball via a connecting shaft. The upper end of the fixing strip is provided with a sliding groove that slides in connection with the ball, and the lower end of the bearing plate is symmetrically connected with sliding strips.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. The position information of the carrier plate is sensed by the first touch switch and fed back to the PLC controller. Then, the PLC controller turns off the switch of the first electromagnet. Subsequently, the iron block that was magnetically attracted to it loses its magnetic attraction, and the spring rebounds and resets. The spring drives the support block, support column and iron block to move upward, so that the support column drives the stop block to move into the positioning groove until the positioning groove is in contact with the second touch switch on the outside of the stop block, restricting the movement of the carrier plate and its outer frame. This facilitates the initial automated positioning of the carrier plate and the stand, effectively improving the positioning effect.
[0017] 2. The second touch switch triggers the positioning sensor information and feeds it back to the PLC controller. Subsequently, the PLC controller automatically turns on the switch of the second electromagnet with the same magnetic pole at the lower end of the magnetic block, so that the magnetic block moves in the opposite direction instantly. This causes the magnetic block to move the fixing sleeve, connecting column and positioning block upward. Then the positioning block is engaged in the positioning hole at the lower end of the second fixing block, which facilitates the positioning and fixing of the entire supporting mechanism and the stand, making it convenient for the screen printing machine to quickly and accurately print on it. This effectively improves the printing stability of the stand. Furthermore, the belt conveyor automatically drives the support plate and the stand to be transported, which facilitates the automated and rapid printing production line of the stand and improves the printing efficiency.

Detailed Implementation
[0026] 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.
[0027] Please see Figure 1-3 As shown in Figure 6, a positioning structure for a printed stand includes a belt conveyor 1, a positioning mechanism 2, and a screen printing machine 3. The screen printing machine 3 is located in the middle of one side of the belt conveyor 1. The positioning mechanism 2 is installed on both sides of the belt conveyor 1. The positioning mechanism 2 includes two sets of fixing strips 21 installed on both sides of the belt conveyor 1. The belt of the belt conveyor 1 carries a bearing mechanism 4. The bearing mechanism 4 includes a bearing plate 41. The upper end of the bearing plate 41 is provided with a bearing groove, and the lower end of the bearing plate 41 is symmetrically connected with sliding strips 42.
[0028] By placing the support plate 41 on the belt of the belt conveyor 1, and the slide bar 42 at the lower end of the support plate 41 contacting the belt of the belt conveyor 1, the belt conveyor 1 can drive the slide bar 42 to move and transport. Subsequently, the slide bar 42 drives the support plate 41 to move. The size and depth of the support groove at the upper end of the support plate 41 can be designed according to different stand-up products to match each stand-up product. The thickness of the stand-up product is greater than the depth of the support groove, making it convenient for workers to pick up. Two slots can be opened at the upper end of the support plate 41 to further facilitate product retrieval.
[0029] An outer frame 43 is installed on the outer side of the support plate 41. An insertion component is installed on the outer side of the outer frame 43 to be inserted into the first positioning component and the second positioning component. The insertion component includes a first fixing block 44 installed on both sides of the outer frame 43. A positioning groove 45 is provided on the outer side of the first fixing block 44 to be inserted into the stop block 210.
[0030] The plug-in assembly also includes a second fixing block 46 installed on both sides of the outer frame 43, and the lower end of the second fixing block 46 is provided with a positioning hole 47 for plugging into the positioning block 217.
[0031] Support sleeves 48 are installed around the lower end of the outer frame 43. The lower part of the inner cavity of each support sleeve 48 is movably connected to a ball bearing 49 via a connecting shaft. The upper end of the fixing strip 21 is provided with a sliding groove 22 that slides in connection with the ball bearing 49.
[0032] After the carrier plate 41 is moved by the belt conveyor 1, the carrier plate 41 and its outer frame 43 move synchronously. The support sleeve 48 at the lower end of the outer frame 43 slides stably in the inner cavity of the slide groove 22 through the ball 49, which effectively improves the stability of the movement and transportation of the outer frame 43 and the carrier plate 41. Then, the positioning groove 45 is used to limit the insertion with the first positioning component, and the positioning hole 47 is engaged with the positioning block 217, which facilitates the positioning and fixing of the outer frame 43 and the carrier plate 41. This makes it convenient for the screen printing machine 3 to position and print the stand, which effectively improves the printing stability of the stand. Moreover, the automatic conveyor belt 1 drives the carrier plate 41 and the stand to be transported, which facilitates the automatic and rapid printing of the stand and improves the printing efficiency.
[0033] Please see Figure 1-5 As shown, each fixing strip 21 has a mounting groove in the middle, and a first touch switch 23 is installed in the inner cavity of each mounting groove. Each fixing strip 21 has a first mounting hole 25 and a second mounting hole 220 at its upper end. A first positioning component and a second positioning component are installed in the inner cavities of the first mounting hole 25 and the second mounting hole 220, respectively. The first positioning component includes a first electromagnet 24 installed in the lower part of the inner cavity of the first mounting hole 25. A mounting block 28 is installed in the inner cavity of the first mounting hole 25. A support column 29 is movably inserted into the middle of the mounting block 28. A support block 26 is connected to the outside of the support column 29. A spring 27 is connected between the support block 26 and the mounting block 28. An iron block 212 is connected to the lower end of the support column 29. A stop block 210 is connected to the upper end of the support column 29. A second touch switch 211 is installed in the middle of the stop block 210.
[0034] The second positioning component includes a second electromagnet 213 installed in the lower part of the inner cavity of the second mounting hole 220. A magnetic block 214 is movably arranged in the inner cavity of the second mounting hole 220. A fixing sleeve 215 is installed on the outer side of the magnetic block 214. A connecting post 216 is equidistantly connected to the upper end of the fixing sleeve 215. A positioning block 217 is connected to the upper end of the connecting post 216. A limiting groove 218 is symmetrically arranged in the inner cavity of the second mounting hole 220. A limiting block 219 is movably arranged in the inner cavity of each limiting groove 218. The limiting blocks 219 are all integrally connected to the fixing sleeve 215.
[0035] When the support plate 41 and its outer frame 43 move, the first touch switch 23 receives the position information of the support plate 41 and feeds this information back to the PLC controller on the outside. Subsequently, the PLC controller turns off the switch of the first electromagnet 24. After the first electromagnet 24 is de-energized, the iron block 212 that was magnetically attracted to it loses its magnetic attraction, causing the stretched spring 27 to rebound and reset. Then, the spring 27 drives the support block 26, the support column 29, and the iron block 212 to move upward. As a result, the support column 29 drives the stop block 210 to move upward to the inner cavity of the first mounting hole 25. At this time, the support plate 41 and its outer frame 43 gradually move to the position of the stop block 210, and the stop block 210 is inserted into the positioning groove 45 on the outside of the first fixing block 44. The support plate 41 and its outer frame 43 continue to move until the positioning groove 45 and the second touch switch 23 on the outside of the stop block 210 are engaged. The 11 phases are pressed together to restrict the movement of the support plate 41 and its outer frame 43. At this time, the second touch switch 211 triggers the positioning sensing information and feeds it back to the PLC controller. Then the PLC controller automatically turns on the switch with the same magnetic pole at the lower end of the second electromagnet 213 and the magnetic block 214. As a result, the magnetic block 214, which is magnetically attracted to the second electromagnet 213, moves in the opposite direction. The magnetic block 214 drives the fixing sleeve 215, the connecting column 216 and the positioning block 217 to move upward. The fixing sleeve 215 moves upward stably in the inner cavity of the limiting groove 218 through the limiting block 219, which helps to improve the stability of the movement of the magnetic block 214. Then the positioning block 217 is inserted into the positioning hole 47 at the lower end of the second fixing block 46, which helps to position and fix the entire support mechanism 4, thereby positioning and fixing the stand-up sign it supports, which facilitates the screen printing machine 3 to quickly and accurately print on it.
[0036] Working principle: An external PLC controller is connected to the belt conveyor 1 via a programmed control system, which includes the first touch switch 23, the first electromagnet 24, the second touch switch 211, and the screen printing machine 3. This programming connection is existing technology and will not be elaborated upon here. During operation, the operator places the carrier mechanisms 4, each carrying a signboard, onto the belt conveyor 1, with a certain interval between each carrier plate 41. As the carrier plates 41 and their outer frames 43 move, the first touch switch 23 receives the position information of the carrier plates 41 and feeds this information back to the external PLC controller. The LC controller then turns off the switch of the first electromagnet 24. After the first electromagnet 24 is de-energized, the iron block 212, which was magnetically attracted to it, loses its magnetic force. This causes the stretched spring 27 to rebound and reset. The spring 27 then moves the support block 26, support column 29, and iron block 212 upwards. The support column 29 then moves the stop block 210 upwards into the positioning groove 45. Meanwhile, the bearing plate 41 and its outer frame 43 continue to move until the positioning groove 45 comes into contact with the second touch switch 211 on the outside of the stop block 210, thus controlling the movement of the bearing plate 41 and its outer frame 43. When the second touch switch 211 triggers the position sensing information and feeds it back to the PLC controller, the PLC controller automatically turns on the switch with the same magnetic pole at the lower end of the second electromagnet 213 and the magnetic block 214. This causes the magnetic block 214, which is magnetically attracted to the second electromagnet 213, to move instantaneously in the opposite direction. This causes the magnetic block 214 to move the fixing sleeve 215, connecting post 216, and positioning block 217 upwards. The fixing sleeve 215 is then stabilized and moved upwards within the limiting groove 218 by the limiting block 219, improving the stability of the magnetic block 214's movement. Subsequently, the positioning block 217 engages with the lower end of the second fixing block 46. The positioning hole 47 facilitates the positioning and fixing of the entire support mechanism 4, thereby positioning and fixing the stand it supports, which makes it convenient for the screen printing machine 3 to quickly and accurately print on it. At this time, the multiple support plates 41 behind are still moving. After the screen printing machine 3 finishes printing on the current stand, the stop block 210 and positioning block 217 of the positioning mechanism 2 are all quickly reset. Then, the stand continues to move forward with the support plate 41. The multiple support plates 41 behind are positioned and fixed one by one by the positioning mechanism 2 before the stand printing operation is carried out, which effectively improves the automated printing effect of the stand and improves the work efficiency.
