Description

Technical Field

[0001] The invention relates to the technical field of screen printers, and in particular to a screen printer for a chemical anchor glass tube body. Background Art

[0002] Chemical anchors are commonly used fasteners in construction and are widely used in the fixation or reinforcement of curtain wall structures, mechanical equipment, steel structure guardrails and windows. Chemical anchors are more powerful, firm and reliable than ordinary anchors. Chemical anchors are mainly composed of chemicals and metal screws. There are two main types of chemicals used with chemical anchors. One is a quick-drying glass hose made of modified vinyl resin, quartz sand and curing agent, and the other is a slow-drying rebar glue made of modified epoxy resin and curing agent. The glass hose is commonly used. When in use, first put the glass tube into the hole, and the staff screws in the screw with an electric drill. After the screw breaks the glass tube and screws it into the hole, the sealed connection can be completed.

[0003] In order to improve the identification and recognition of the product, it is also necessary to print the product model, production date, expiration date, instructions for use and other information on the chemical anchor glass tube. This information is used to help users understand the basic information and characteristics of the product, so as to make the right choice and use it. At this time, a silk screen printer will be used to print this information. Silk screen printing is a method of printing text, patterns or logos on the surface of an object. In the chemical anchor glass tube, silk screen printing can be used to print various information, and can also help identify different batches of chemical anchors to avoid confusion and misuse.

[0004] A screen printer is a printing device widely used in various industries. It can print the required images, text or other logos onto the surfaces of different objects. During the printing process, the surface of the object to be printed needs to be processed so that it can fully contact with the ink. During the printing stage, the ink leaks through the screen and is evenly printed on the surface of the object. When the ink dries, a stable printed pattern will be formed. However, before screen printing, if there are impurities attached to the surface of the glass tube, or if the clamping position of the glass tube deviates during the printing process, it may lead to poor printing effect or peeling of the printed layer, or the printed pattern may be of different sizes or offset, which greatly affects the printing quality and efficiency.

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figures 1 to 11As shown, this embodiment proposes a screen printer for chemical anchor glass tubes, including a conveyor 1, a feeding frame 2, a feeding assembly, a driving assembly, a supporting frame 3, a rotating frame 4, a clamping assembly, a positioning assembly, a fixed frame 5 and a printing assembly. The feeding frame 2 is fixedly installed on the side of the conveyor 1, and the feeding assembly is installed on the feeding frame 2 to feed the glass tube into the screen printing position. The feeding assembly includes a loading frame 6, a material placement trough 7, a rotating shaft 8, a swing frame 9, a clamping frame 10, a discharging frame 11 and a clamping part. The loading frame 6 is fixedly installed On the feeding frame 2, a plurality of material placing troughs 7 are provided at equal intervals on the loading frame 6, two rotating shafts 8 are rotatably installed on the feeding frame 2, the rotating shafts 8 are located at the lower part of the loading frame 6, swing frames 9 are symmetrically and fixedly installed on the two rotating shafts 8, the loading frame 6 is located between the two swing frames 9, the clamping frame 10 is arranged on the upper part of the loading frame 6, the bottom of the clamping frame 10 is rotatably connected to the top of the four swing frames 9, the discharging frame 11 is fixedly installed at one end of the loading frame 6 away from the conveyor 1, and the clamping part is installed on the clamping frame 10, which is used to clamp the glass tube to be printed.

[0024] Specifically, when the chemical anchor glass tube is screen-printed, the glass tube to be screen-printed is first placed on the conveyor 1, and the conveyor 1 is started. The conveyor 1 drives the glass tube to move until the glass tube moves to the clamping part. At this time, the clamping part is started to clamp the glass tube, and the driving component is started to drive the rotating shaft 8 to swing back and forth. The rotating shaft 8 can drive the swing frame 9 to swing, and the swing frame 9 drives the clamping frame 10 to swing. At the same time, the clamping frame 10 is kept parallel to the feeding frame 2. When the clamping frame 10 moves to the position closest to the conveyor 1, the position of the clamping part corresponds to the material placement slot 7, and the electric-controlled clamping claw 13 is just above the glass tube on the conveyor 1. At this time, the electric-controlled clamping claw 13 is started to clamp the glass tube. The glass tube, at this time, the clamping rack 10 starts to move away from the conveyor 1. When the clamping rack 10 moves to the position closest to the supporting rack 3, the glass tube on the electric-controlled clamping claw 13 is just located on the material loading slot 7 closest to the conveyor 1. At this time, the electric-controlled clamping claw 13 can be released, and the glass tube can be placed on the material loading slot 7. As the clamping rack 10 continues to swing, the glass tube can be slowly transported to the discharging rack 11. When the glass tube moves to the discharging rack 11, the clamping assembly is started to clamp the position of the glass tube, and then the positioning assembly is started to move the glass tube to the printing position. At this time, the positioning assembly is started to calibrate the glass tube on the clamping assembly, and then the printing assembly is started to print the glass tube.

[0025] The above, such as Figure 4As shown, the clamping part includes a mounting frame 12, an electric-controlled clamping claw 13, a first electric cylinder 14 and a clamping block 15. The mounting frame 12 is fixedly mounted on one end of the clamping frame 10 close to the conveyor 1, the electric-controlled clamping claw 13 is fixedly mounted on the bottom of the mounting frame 12, and the first electric cylinders 14 are fixedly mounted on both sides of the clamping frame 10 at equal distances. The multiple first electric cylinders 14 correspond one-to-one to the multiple material placing slots 7, and the output end of each first electric cylinder 14 is fixedly mounted with a clamping block 15.

[0026] Specifically, during the loading process, when the clamping rack 10 moves to the position closest to the conveyor 1, the mounting frame 12 is just above the glass tube on the conveyor 1. At this time, the electric-controlled clamp 13 can be started to clamp the glass tube. As the clamping rack 10 swings, the clamping rack 10 drives the electric-controlled clamp 13 to move through the mounting frame 12. When the clamping rack 10 moves to the position closest to the supporting frame 3, the glass tube on the electric-controlled clamp 13 is just located on the loading trough 7 closest to the conveyor 1. As the clamping rack 10 continues to swing, the first electric cylinder 14 also continuously pushes the clamping block 15 to move back and forth, thereby clamping the glass tube on the loading trough 7, and moving the corresponding glass tube to the adjacent loading trough 7 away from the conveyor 1 until the glass tube is moved to the unloading rack 11.

[0027] like Figure 5 , Figure 6 As shown, the driving assembly is installed on the feeding frame 2, and is used to drive the feeding assembly to intermittently move. The driving assembly includes a sprocket 16, a chain 17, a shell 18 and a driving part. The sprocket 16 is fixedly installed at one end of the two rotating shafts 8, and the chain 17 is meshed between the two sprockets 16. The shell 18 is fixedly installed on the feeding frame 2, and the driving part is installed on the shell 18, and is used to drive the two rotating shafts 8 to swing back and forth.

[0028] Specifically, when driving the clamping frame 10 to swing, through the setting of the driving part, the driving part drives the two sprockets 16 to reciprocate through the setting of the chain 17, thereby driving the rotating shaft 8 to frequently rotate forward and reverse, and thus driving the swing frame 9 to swing back and forth through the rotating shaft 8.

[0029] The above, such as Figure 6 As shown, the driving part includes a driving gear 19, a driven gear 20, a slide 21, a first motor 22, a turntable 23 and a connecting block 24. The driving gear 19 is rotatably mounted on the housing 18, the driven gear 20 is fixedly mounted on one of the sprockets 16, the driven gear 20 is meshed with the driving gear 19, the driving gear 19 is fixedly mounted with a slide 21, the first motor 22 is fixedly mounted on the housing 18, the turntable 23 is fixedly mounted on the output end of the first motor 22, the turntable 23 is fixedly mounted with a connecting block 24, the connecting block 24 is eccentrically arranged, and the connecting block 24 and the slide 21 are slidably matched.

[0030] Specifically, when driving the two sprockets 16 to perform frequent forward and reverse rotation synchronously, the first motor 22 is started, the first motor 22 drives the turntable 23 to rotate, the turntable 23 drives the connecting block 24 to rotate around the axis of the turntable 23, thereby driving the slide groove 21 to swing around the axis position of the driving gear 19, thereby driving the driving gear 19 to swing, at this time the connecting block 24 and the slide groove 21 slide relative to each other, at this time the driving gear 19 starts to switch frequently between forward and reverse rotation, thereby driving the sprocket 16 to perform frequent forward and reverse rotation through the setting of the driven gear 20.

[0031] like Figures 7 to 10 As shown, the supporting frame 3 is fixedly mounted on one end of the feeding frame 2 away from the conveyor 1, the rotating frame 4 is rotatably mounted on the supporting frame 3, the clamping assembly is mounted on the rotating frame 4, and is used to place the glass tube to be printed, the clamping assembly includes a mounting plate 25, a rotating shell 26, a sliding frame 27, a second electric cylinder 28 and a clamping block 29, and a plurality of mounting plates 25 are fixedly mounted at equal angles on both ends of the rotating frame 4, and the plurality of mounting plates 25 at both ends of the rotating frame 4 correspond to each other one by one, a rotating shell 26 is rotatably mounted on the plurality of mounting plates 25, and a sliding frame 27 is slidably mounted inside the plurality of rotating shells 26, a second electric cylinder 28 is fixedly mounted on each rotating shell 26, and an output end of the second electric cylinder 28 is fixedly connected to the sliding frame 27, and a clamping block 29 is detachably mounted on each sliding frame 27.

[0032] Specifically, before work, a suitable clamping block 29 is installed according to the specifications of the glass tube. When the glass tube moves to the discharge rack 11, the glass tube is just located between the two mounting plates 25. At this time, the second electric cylinder 28 is started, and the second electric cylinder 28 drives the sliding rack 27 to move on the rotating shell 26 until the two sliding racks 27 respectively drive the clamping blocks 29 to contact the two ends of the glass tube, thereby fixing the position of the glass tube. When the position of the glass tube needs to be adjusted, the second electric cylinder 28 is released to loosen the clamping block 29 and the glass tube. At this time, the position of the glass tube can be adjusted. After adjustment, the second electric cylinder 28 is started again to fix the glass tube through the clamping block 29.

[0033] like Figures 7 to 10As shown, the position adjustment component is installed on the rotating frame 4, and is used to adjust the position of the glass tube to be printed. The position adjustment component includes a second motor 30, a first gear 31, a second gear 32, a third motor 33, a third gear 34 and a position adjustment part. The second motor 30 is fixedly installed on the fixed frame 5, and the output end of the second motor 30 is fixedly connected to the rotating frame 4. The first gear 31 is fixedly installed on each rotating shell 26. A plurality of second gears 32 are equiangularly mounted on the rotating frame 4, and the second gear 32 is meshed with the first gear 31. The third motor 33 is fixedly installed on the rotating frame 4, and the output end of the third motor 33 is fixedly installed with a third gear 34, and the third gear 34 is respectively meshed with the plurality of second gears 32. The position adjustment part is installed on the rotating frame 4, and is used to adjust the position of the glass tube.

[0034] Specifically, when printing on the glass tube, the second motor 30 is started, and the second motor 30 drives the rotating frame 4 to rotate, thereby driving the clamped glass tube to move to the printing position. At this time, the second motor 30 is closed and locked, thereby fixing the position of the rotating frame 4, and then the clamping position of the glass tube is adjusted by the adjustment part. At this time, in order to further improve the printing effect, the third motor 33 is started, and the third motor 33 drives the third gear 34 to rotate, and the third gear 34 drives the second gear 32 to rotate, and the second gear 32 drives the first gear 31 to rotate, thereby driving the rotating shell 26 to rotate through the first gear 31, thereby driving the glass tube to rotate, cleaning its surface, increasing the adhesion of the glass tube surface, and improving the printing quality. Then, during the printing process, through the setting of the third motor 33, the glass tube can also be driven to rotate, so as to cooperate with the printing component for printing.

[0035] The above, such as Fig.10 As shown, the positioning part includes a positioning frame 35, a movable frame 36, a third electric cylinder 37, a positioning roller 38 and a sponge strip 39. A plurality of positioning frames 35 are fixedly installed at equal angles on the rotating frame 4. The plurality of positioning frames 35 correspond one-to-one to the plurality of mounting plates 25. A movable frame 36 is slidably installed on the plurality of positioning frames 35. A third electric cylinder 37 is fixedly installed inside each positioning frame 35. The output end of the third electric cylinder 37 is fixedly connected to the movable frame 36. Two positioning rollers 38 are symmetrically and rotatably installed on the upper part of each movable frame 36. A sponge strip 39 is detachably installed on each movable frame 36. The sponge strip 39 is located between the two positioning rollers 38.

[0036] Specifically, when the rotating frame 4 drives the glass tube to move to the printing position, the third electric cylinder 37 can be started, and the third electric cylinder 37 drives the moving frame 36 to slide on the positioning frame 35, thereby driving the positioning roller 38 to move through the moving frame 36 until the positioning roller 38 contacts the glass tube. At this time, the sponge bar 39 also contacts the glass tube, and the glass tube can be cleaned. In order to maintain the cleaning efficiency, the sponge bar 39 can be replaced regularly. As the moving frame 36 moves, the positioning roller 38 drives the glass tube to move until the axial position of the glass tube coincides with the axial position of the first gear 31, and then the third electric cylinder 37 can be closed and locked, and then the glass tube can be refixed, and the third electric cylinder 37 can be retracted.

[0037] like Fig.11 As shown, the fixed frame 5 is fixedly installed on one side of the supporting frame 3, the printing component is installed on the fixed frame 5 for printing the glass tube, the printing component includes a sliding frame 40, a fourth electric cylinder 41 and a printing part, the sliding frame 40 is slidably installed on the fixed frame 5, the sliding frame 40 is located on the upper part of the rotating frame 4, the fourth electric cylinder 41 is fixedly installed on the fixed frame 5, the output end of the fourth electric cylinder 41 is fixedly connected to the sliding frame 40, and the printing part is installed on the sliding frame 40 for printing the glass tube.

[0038] Specifically, when printing on the glass tube, the fourth electric cylinder 41 is started, and the fourth electric cylinder 41 drives the sliding frame 40 to move until the sliding frame 40 moves to the working position, and then the fourth electric cylinder 41 can be closed and locked. At this time, ink is added to the printing part, and the printing part is started to print on the glass tube.

[0039] The above, such as Fig.11 As shown, the printing unit includes a printing screen 42, a fifth electric cylinder 43, a sixth electric cylinder 44, a scraper 45, a seventh electric cylinder 46 and an ink return knife 47.

[0040] Specifically, when printing on the glass tube, it is necessary to first install a suitable printing screen 42, and then add ink to the printing screen 42. The ink is located between the ink scraper 45 and the ink return knife 47. At this time, the seventh electric cylinder 46 is started, and the seventh electric cylinder 46 drives the ink return knife 47 to move until the ink return knife 47 contacts the printing screen 42. At this time, the corresponding fifth electric cylinder 43 is started to drive the printing screen 42 to move. The movement of the printing screen 42 causes a relative displacement between the printing screen 42 and the ink return knife 47, so that the ink is evenly attached to the printing position of the printing screen 42 through the setting of the ink return knife 47. When printing on the glass tube, the seventh electric cylinder 46 is retracted and the sixth electric cylinder 44 is started. At this time, the ink scraper 45 contacts the printing screen 42, and the ink return knife 47 is separated from the printing screen 42. Another fifth electric cylinder 43 is started to drive the printing screen 42 to move in the opposite direction. At this time, the bottom of the printing screen 42 contacts the glass tube. At the same time, as the printing screen 42 moves, the glass tube also rotates synchronously at a constant speed. At this time, through the setting of the ink scraper 45, the required pattern or text can be printed on the glass tube, and then it can be dried, and the printed glass tube can be taken down, collected and stored.

Then, during the printing process, the third motor 33 can also drive the glass tube to rotate, thereby cooperating with the printing component to print.

[0046] In order to maintain the cleaning efficiency, the sponge strip 39 can be replaced regularly. As the movable frame 36 moves, the positioning roller 38 drives the glass tube to move until the axial position of the glass tube coincides with the axial position of the first gear 31. Then, the third electric cylinder 37 can be closed and locked, and the second electric cylinder 28 can be started again. The glass tube is fixed by the clamping block 29, and then the glass tube is re-fixed, and the third electric cylinder 37 can be retracted.

[0047] At this time, printing can be started. When printing on the glass tube, it is necessary to install a suitable printing screen 42 first, and then add ink on the printing screen 42. The ink is located between the scraper 45 and the ink return knife 47. The fourth electric cylinder 41 is started, and the fourth electric cylinder 41 drives the sliding frame 40 to move until the sliding frame 40 moves to the working position. The fourth electric cylinder 41 can be closed and locked. At this time, the seventh electric cylinder 46 is started, and the seventh electric cylinder 46 drives the ink return knife 47 to move until the ink return knife 47 contacts the printing screen 42. At this time, the corresponding fifth electric cylinder 43 is started to drive the printing screen 42 to move. The movement of the printing screen 42 causes a relative movement between the printing screen 42 and the ink return knife 47. Displacement, so that the ink is evenly attached to the printing position of the printing screen 42 through the setting of the ink return knife 47. When printing on the glass tube, the seventh electric cylinder 46 is retracted and the sixth electric cylinder 44 is started. At this time, the ink scraper 45 contacts the printing screen 42, and the ink return knife 47 is separated from the printing screen 42. Another fifth electric cylinder 43 is started to drive the printing screen 42 to move in the opposite direction. At this time, the bottom of the printing screen 42 contacts the glass tube. At the same time, as the printing screen 42 moves, the glass tube also rotates synchronously at a constant speed. At this time, through the setting of the ink scraper 45, the required pattern or text can be printed on the glass tube, and then it can be dried, and the printed glass tube can be taken down, collected and stored.
