Description

Technical Field

[0001] This utility model relates to the technical field of vibration feeding structure for two-color pad printing machines, specifically a vibration feeding structure for two-color pad printing machines. Background Technology

[0002] Currently, Chinese Patent CN221587126U discloses a feeding device for pad printing machines, relating to the field of feeding device technology. Addressing the problem that existing technologies still rely on manual placement of objects to be printed, resulting in significant limitations in work efficiency and hindering production improvement, this invention proposes the following solution: a toggle mechanism and a push mechanism. The toggle mechanism includes a support platform, inclined plates fixed to the inner walls at both ends of the support platform, fixed plates fixed to the top ends of the support platform, and a threaded rod rotatably connected between the two fixed plates. This invention uses a conveyor belt to transport the objects to be printed. When an infrared sensor detects an object, a push rod motor extends and pushes a T-shaped plate to push the object into a positioning frame to cooperate with the pad printing machine for printing. After printing, a servo motor drives a movable block to move laterally left and right through the rotating threaded rod, moving the printed object in the positioning frame to the inclined plate to slide out, thus automating the feeding and unloading process.

[0003] The feeding device used in the above-mentioned pad printing machine has some problems in actual use. The size of the positioning frame is fixed and can only be adapted to workpieces of specific sizes. When processing workpieces of different specifications, the positioning frame cannot effectively fit the workpiece, which may cause the workpiece to shift or tip over during the turning process. The positioning frame needs to be replaced frequently, which is cumbersome and has low versatility. Utility Model Content

[0004] The purpose of this invention is to provide a vibration feeding structure for a two-color pad printing machine to solve the problems mentioned in the background art.

Mounting holes for mounting on the surface of the two-color pad printing machine are provided on the front side edge of the conveyor belt. A positioning frame is fixedly installed on the upper left side of the conveyor belt and at a position opposite to the processing end of the two-color pad printing machine. Several sets of pushing components are provided on the surface of the conveyor belt for pushing workpieces located at the bottom of the storage component into the positioning frame. A detection component for detecting the position of the workpiece is installed on the right side of the positioning frame.

[0007] As a preferred technical solution, the pushing component includes several sets of equidistantly arranged rubber pads fixedly installed on the surface of the conveyor belt. Each set of rubber pads has a mounting housing attached to its top. Each set of mounting housings has clamping plates at both ends of its left side for clamping the workpiece. Each set of mounting housings has an adjustment component inside for adjusting the distance between the two sets of clamping plates on the corresponding side according to the width of the workpiece.

[0008] As a preferred technical solution, the adjustment component includes a square hole opened at the left end of each set of mounting housings and arranged along its length. A gear is rotatably connected inside each set of mounting housings. A rack meshes with the left and right sides of each set of gears.

The ends of the two sets of connecting plates in the same position pass through the corresponding side square holes and are fixedly connected to the ends of the corresponding side clamps. A fixing member for fixing one set of racks is provided on the right side of each set of mounting housings.

[0009] As a preferred technical solution, the fastener includes a limiting hole formed on the upper right surface of each set of mounting housings and arranged along the length. A fixing bolt is inserted into the inner cavity of each set of limiting holes. One end of each set of fixing bolts is fixedly connected to the upper right surface of the corresponding rack. The other end of each fixing bolt is threaded with a fixing nut. Tightening each set of fixing nuts causes its end to abut against the corresponding side surface of the mounting housing.

[0010] As a preferred technical solution, a scale is fixedly connected to the top left side of each set of mounting housings, and a pointer for pointing to the scale is fixedly installed on the top of the clamp on the top left side of each set of mounting housings.

[0011] As a preferred technical solution, guide bars are fixedly connected to the top of the two sets of racks respectively, and the tops of the two sets of guide bars are slidably connected to the top inner wall of the corresponding side mounting housing. The cross-section of each set of guide bars is T-shaped.

[0012] As a preferred technical solution, the storage component includes a mounting plate fixedly installed on the upper right side of the conveyor belt. A storage tube is fixedly inserted into the top of the mounting plate. U-shaped plates are inserted into the inner walls of both the front and rear sides of the storage tube. Movable parts for adjusting the distance between the two sets of U-shaped plates according to the width of the workpiece are provided on both the front and rear sides of the storage tube.

[0013] As a preferred technical solution, the movable component includes hand-tightening bolts that are threaded to the front and rear surfaces of the storage tube, respectively. The ends of the two sets of hand-tightening bolts penetrate the corresponding side surfaces of the storage tube and are rotatably connected to the corresponding side U-shaped plate surfaces.

[0029] 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.

[0030] Please see Figure 1-5 This embodiment provides a vibration feeding structure for a two-color pad printing machine, including a conveyor belt 100. A storage component for storing workpieces is provided on the upper right side of the conveyor belt 100. The front side guard 101 of the conveyor belt 100 is provided with mounting holes 102 for mounting on the surface of the two-color pad printing machine body. A positioning frame 103 is fixedly installed on the upper left side of the conveyor belt 100 and at a position relative to the processing end of the two-color pad printing machine. A plurality of pushers are provided on the surface of the conveyor belt 100 for pushing the workpiece located at the bottom of the storage component into the position below the positioning frame 103. A detection component for detecting the position of the workpiece is installed on the right side of the positioning frame 103.

[0031] The pushing component includes several sets of equidistantly arranged rubber pads 201 fixedly installed on the surface of the conveyor belt 100. Each set of rubber pads 201 has a mounting housing 200 bonded to its top. Each set of mounting housings 200 has clamping plates 202 at both the front and rear ends of its left side for holding the workpiece. Each set of mounting housings 200 has an adjustment assembly inside for adjusting the distance between the two sets of clamping plates 202 on the corresponding side according to the workpiece width. Through the arrangement of the pushing component, the rubber pads 201 in the pushing component can reduce the vibration and friction between the mounting housings 200 and the conveyor belt 100 during operation, providing a buffering and protective function. Furthermore, the equidistantly arranged mounting housings 200 can achieve continuous workpiece conveying, improving processing efficiency; the clamping plates 202 can clamp the workpiece, preventing it from shifting or falling during conveying.

[0032] The adjustment assembly includes a square hole 203 located at the left end of each mounting housing 200 and extending along its length. Each mounting housing 200 has a gear 210 rotatably connected inside. Each gear 210 has a rack 208 meshing with its left and right sides. Two racks 208 in the same position have connecting plates 206 fixedly connected to their left ends. The ends of the two connecting plates 206 in the same position pass through the corresponding square holes 203 and are fixedly connected to the ends of the corresponding clamping plates 202. Each mounting housing 200 has a fixing member on its right side for securing one of the racks 208. Through the adjustment assembly, the meshing transmission between the gears 210 and racks 208 enables the two clamping plates 202 to move synchronously in opposite directions. This allows for flexible adjustment of the distance between the two clamping plates 202 according to the workpiece width, making the pusher suitable for workpieces of different widths, enhancing the versatility of the device, and ensuring the convenience and symmetry of the distance adjustment.

[0033] The fasteners include limiting holes 213 formed on the upper right surface of each set of mounting housings 200 and arranged along the length. Each set of limiting holes 213 has a fixing bolt 212 inserted into its inner cavity. One end of each fixing bolt 212 is fixedly connected to the upper right surface of the corresponding rack 208, and the other end of each fixing bolt 212 is threadedly connected to a fixing nut 211. Tightening each set of fixing nuts 211 so that its end abuts against the corresponding side surface of the mounting housing 200 allows the rack 208 to be quickly fixed or loosened, facilitating flexible adjustment according to the workpiece width. The limiting holes 213 provide space for the movement of the fixing bolts 212, adapting to the fixing requirements of the rack 208 at different positions. Tightening the fixing nuts 211 so that they abut against the surface of the mounting housing 200 effectively prevents the rack 208 from loosening and ensures the stability of the spacing between the clamps 202.

[0034] Each set of mounting housings 200 has a scale 205 fixedly connected to the top left side. Each set of mounting housings 200 has a pointer 207 fixedly installed on the top of the clamping plate 202 located on the top left side of the clamping plate 202, which is used to point to the scale 205. Through the setting of the pointer 207 and the scale 205, the cooperation between the scale 205 and the pointer 207 can intuitively display the size of the gap when adjusting the gap of the clamping plate 202, which is convenient for operators to accurately control, improve the accuracy and efficiency of the gap adjustment, and avoid workpiece instability or incompatibility due to improper adjustment.

[0035] The tops of the two sets of racks 208 are respectively fixedly connected to guide bars 209. The tops of the two sets of guide bars 209 are slidably connected to the top inner wall of the corresponding side mounting housing 200. The cross-section of each set of guide bars 209 is T-shaped. Through the setting of guide bars 209, the sliding connection between the T-shaped guide bars 209 and the top inner wall of the mounting housing 200 can guide and limit the movement of racks 208, prevent racks 208 from deviating or tilting during movement or operation, ensure the stability of meshing between gear 210 and racks 208, and thus ensure the accuracy of clamping plate 202 spacing adjustment and clamping reliability.

[0036] The storage component includes a mounting plate 301 fixedly installed on the upper right side of the conveyor belt 100. A storage tube 300 is fixedly inserted into the top of the mounting plate 301. U-shaped plates 302 are inserted into the inner walls of both the front and rear sides of the storage tube 300. Movable parts are provided on both the front and rear sides of the storage tube 300 to adjust the distance between the two sets of U-shaped plates 302 according to the width of the workpiece. Through the setting of the storage component, the storage tube 300 can realize the stacking and storage of workpieces, reducing the trouble of frequent feeding. At the same time, the U-shaped plates 302 can play a lateral limiting role for the workpieces in the storage tube 300, preventing the workpieces from shifting during storage or falling. The movable parts can adjust the distance between the two sets of U-shaped plates 302 according to the width of the workpiece, making the storage component suitable for workpieces of different widths and improving the versatility of the storage component.

[0037] The movable component includes hand-tightening bolts 303 threadedly connected to the front and rear surfaces of the storage tube 300. The ends of the two sets of hand-tightening bolts 303 penetrate the corresponding side surfaces of the storage tube 300 and are rotatably connected to the corresponding side surfaces of the U-shaped plates 302. With the movable component, the U-shaped plates 302 are moved by the hand-tightening bolts 303, which is simple and labor-saving to operate and facilitates quick adjustment of the spacing between the U-shaped plates 302. At the same time, the threaded connection between the hand-tightening bolts 303 and the storage tube 300 can fix the position of the U-shaped plates 302, ensuring the stability of the adjusted spacing and ensuring reliable positioning of the workpiece.

[0038] Among them, anti-drop plates 304 for supporting workpieces are fixedly connected to the bottom of opposite sides of the two sets of U-shaped plates 302. Push plates 204 are fixedly installed on the top of each set of mounting housing 200 and between the two sets of anti-drop plates 304. Through the setting of anti-drop plates 304, anti-drop plates 304 can support the workpieces stacked in the storage tube 300, prevent the workpieces from falling prematurely, and ensure that the workpieces fall in an orderly manner. At the same time, push plates 204 can accurately push the workpieces at the bottom of the storage tube 300 away from the anti-drop plates 304, ensuring that the workpieces smoothly enter the clamping range of the pusher, realizing continuous conveying of workpieces and improving the stability of feeding.

[0039] The detection component includes a Hall sensor 105 fixedly installed on the right end of the positioning frame 103. A permanent magnet 104, matching the Hall sensor 105, is embedded on the top right side of each mounting housing 200. When the pusher moves the workpiece below the positioning frame 103, the permanent magnet 104 corresponds to the Hall sensor 105. The Hall sensor 105 detects the position of the permanent magnet 104 to indicate that the workpiece has reached the processing position. Through this detection component setup, the Hall sensor 105 and the permanent magnet 104 work together to achieve fast response and high detection accuracy, accurately determining whether the workpiece has reached the processing position below the positioning frame 103. Simultaneously, by indirectly detecting the position of the permanent magnet 104, the workpiece position is fed back, avoiding direct contact between the sensor and the workpiece, reducing interference and wear on the workpiece, improving the reliability and service life of the detection, and providing precise signal triggering for the automatic processing of the two-color pad printing machine, thus enhancing the automation level of the processing.

[0040] The Hall sensor 105 can be one of the following: OH44E single-pole switch type Hall sensor 105, ACS724LLCTR-50AB-T, CC6521 / 2 Hall sensor 105, etc., and is connected to the control system of the two-color pad printing machine through the controller 106 of model TMS320F2812.

[0041] The permanent magnet 104 can be selected from one of the following: neodymium iron boron permanent magnet 104, ferrite permanent magnet 104, etc.

[0042] Working principle;

[0043] First, install the entire device on the surface of the two-color pad printing machine body through the mounting holes 102 of the front side guard 101 of the conveyor belt 100, so that the positioning frame 103 is aligned with the processing end of the two-color pad printing machine.

[0044] The workpieces are pre-stacked in the storage tube 300 of the storage component. According to the width of the workpieces, the hand-tightening bolts 303 on the front and rear sides of the storage tube 300 are rotated to drive the corresponding side U-shaped plates 302 to move in the storage tube 300 until the two sets of U-shaped plates 302 are adapted to the width of the workpieces. At this time, the anti-fall plate 304 at the bottom of the U-shaped plate 302 plays a supporting role for the stacked workpieces and prevents the workpieces from falling off in advance.

[0045] After the conveyor belt 100 is started, the mounting housing 200 on the surface moves synchronously with the conveyor belt 100. When the mounting housing 200 moves to the bottom of the storage component, the pusher 204 on the top of the mounting housing 200 will push the workpiece at the bottom of the storage tube 300 to get off the anti-fall plate 304 support and fall between the two sets of clamping plates 202, and move towards the positioning frame 103 together with the pusher.

[0046] Two sets of clamping plates 202 limit the workpiece on both sides to prevent it from shaking or falling during the conveying process. As the conveyor belt 100 continues to run, the workpiece is pushed to the bottom of the positioning frame 103. At this time, the permanent magnet 104 on the top right side of the mounting housing 200 moves with the pusher to the position corresponding to the Hall sensor 105 on the right side of the positioning frame 103. After the Hall sensor 105 detects the permanent magnet 104, the feedback signal indicates that the workpiece has reached the processing position, and the two-color pad printing machine can then perform processing operations on the workpiece in the positioning frame 103.

[0047] When processing workpieces of different widths, loosen the fixing nut 211 in the fixing component, push one set of racks 208 to move within the mounting housing 200, the racks 208 drive the gears 210 to rotate, thereby causing the other set of racks 208 to move in the opposite direction, and the two sets of racks 208 drive the corresponding side clamps 202 to move synchronously through the connecting plate 206.

[0048] During the adjustment process, the pointer 207 on the top of the upper left clamping plate 202 points to the scale 205, which facilitates precise control of the spacing. After adjusting to the width of the workpiece, tighten the fixing nut 211 so that its end abuts against the surface of the mounting housing 200. Fix the position of the rack 208 by fixing the fixing bolt 212 to complete the locking of the spacing of the clamping plate 202.

[0049] Meanwhile, the T-shaped guide bar 209 at the top of the rack 208 slides on the inner wall of the top of the mounting housing 200 to ensure the stability of the rack 208 when it moves and to prevent deviation.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
