Description

Technical Field

[0001] The invention relates to the field of spraying and coding of labels for bottle cap production, and in particular to a device for spraying and coding of labels for bottle cap production and a control method. Background Art

[0002] Bottle cap inkjet printer is a device specially used for printing on the surface of bottle caps. It can clearly print information such as production date, batch number, anti-counterfeiting mark, etc. on the bottle caps.

[0003] During the production process of bottle caps, it is necessary to spray codes on the surface of the bottle caps, and the bottle cap inkjet printer can clearly mark the production date, batch number and other information on the bottle caps. This information provides a basis for product traceability, ensuring that each product can trace its production process, facilitating management and recall. When there are problems with product quality, companies can use this information to quickly locate and recall problematic products to reduce losses. They can also spray codes on the inside of the bottle caps to hold prize-winning activities.

[0004] However, the existing bottle cap inkjet printer can only perform single-sided coding processing on the bottle cap during use, and cannot perform continuous coding processing on the inner and outer surfaces of the bottle cap. Therefore, when performing double-sided coding processing, the bottle cap needs to be turned over and placed on the conveyor belt for secondary coding processing, which makes it impossible to complete the processing of the bottle in one go, thereby failing to improve the efficiency of the bottle cap coding processing.

[0045] The coding component 3 includes a supporting base 33, a threaded rod 37 is rotatably connected to the top of the middle part of the supporting base 33, and limiting vertical rods 32 are arranged at both ends of the supporting base 33. The outer surface of the threaded rod 37 is threadedly connected to a cross frame 34, and the first and second coding devices 31 and 35 are fixedly installed at both ends of the cross frame 34 respectively, and the tops of the first and second coding devices 31 and 35 are fixedly connected with wires 36.

[0046] The supporting component 4 includes a supporting frame 47, an inclined guide rail 41 is welded to the inner bottom end of the supporting frame 47, a collecting box 42 is slidably installed on the upper surface of the inclined guide rail 41, a spiral limit strip 45 is arranged in the middle of the top end of the supporting frame 47, and limiting shaft holes 46 are evenly provided on the two end edges of the spiral limit strip 45, a discharge port 44 is arranged at the top end of the supporting frame 47 and in the middle of one end of the spiral limit strip 45, and a guide plate 43 is fixedly installed at one end of the supporting frame 47 and below the discharge port 44.

[0047] The limiting wheel 15 and the limiting block 16 of the present invention are rotatably connected with the top of the support frame 47 through the limiting shaft hole 46, which can play a limiting role in the rotation of the conveyor belt 110. The first transmission rod 11 and the second transmission rod 13 are rotatably connected with the top two ends of the support frame 47 through the limiting shaft hole 46, which can play a limiting role in the two ends of the conveyor belt 110. The driving motor 19 is fixedly connected to one end of the top of the support frame 47 to ensure the stability of the operation of the driving motor 19. A support plate is set at the end of the spiral limiting strip 45 away from the discharge port 44, and the feeding conduit 23 is fixedly installed at one end of the support frame 47 and is located directly above the support plate. At the same time, the arc-shaped stopper 24 at the bottom of the feeding conduit 23 is fixedly connected to the upper surface of the support plate, so that the bottle cap can be dropped from the inside of the feeding conduit 23 to the upper surface of the support plate, so that the rotating conveyor belt 110 pushes the bottle cap.

[0048] The bevel gear rod 26 of the present invention is meshedly connected with the bevel gear 12 at the top of the first transmission rod 11, so the conveyor belt 110 will drive the bevel gear rod 26 to rotate through the bevel gear 12, so that the bevel gear rod 26 drives the bottle cap conveying rotating block 27 to unload the bottle caps. The upper and lower ends of the outer surface of the bottle cap conveying rotating block 27 are both wedge-shaped, which can prevent the bottle cap conveying rotating block 27 from rotating and squeezing the bottle caps inside the limiting groove 29. The second wedge block 210 is higher than the first wedge block 28 inside the limiting groove 29, which can limit the bottle caps from falling inside the limiting groove 29 to the position of the wedge-shaped end of the bottle cap conveying rotating block 27, affecting the normal rotation of the bottle cap conveying rotating block 27. The wedge-shaped rotation of the outer surface of the bottle cap conveying rotating block 27 is biased towards the second wedge block 210, which can ensure that when the bottle cap conveying rotating block 27 is deflected, the wedge-shaped end can squeeze out the bottle caps that have not fallen normally, so that the bottle caps can be The bottle caps are normally flipped and conveyed inside the cap conveying rotary block 27, and the first wedge block 28 and the second wedge block 210 abut against the outer surface of the bottle cap conveying rotary block 27 inside the limiting groove 29, which can block the gap when the bottle cap conveying rotary block 27 is flipped, and prevent the bottle caps from falling into the gap between the bottle cap conveying rotary block 27 and the limiting groove 29, affecting the normal deflection of the bottle cap conveying rotary block 27. The spiral limiting strip 45 is located on the upper and lower sides of the conveyor belt 110 at the top of the support frame 47, so that the bottle caps conveyed by the conveyor belt 110 can be limited. The second inkjet printer 35 and the first inkjet printer 31 are at the top of both ends of the conveying component 1. Point to the center of the bottle caps, and perform coding processing on the bottle caps conveyed by the conveyor belt 110. The two ends of the cross frame 34 are slidably sleeved on the outer surface of the limiting vertical rod 32, which can limit the lifting and lowering of the two ends of the cross frame 34.

[0049] A control method for a bottle cap production label spraying and coding device, comprising:

[0050] Step 1: first pour the bottle caps into the feeding hopper 5;

[0051] Step 2: Start the driving motor 19 to drive the two sets of conveyor belts 110 to rotate. At the same time, the other end of the conveyor belt 110 will drive the bottle cap conveying rotating block 27 inside the unloading component 2 to rotate, so as to convey the bottle caps inside the feeding hopper 5 to the inside of the feeding conduit 23, and make the bottle caps fall to one end of the two sets of conveyor belts 110. After being conveyed by the conveyor belts 110, the bottle caps will pass through the second inkjet printer 35 for the first inkjet processing;

[0052] Step 3: At the same time, the conveyor belt 110 will continue to convey the bottle caps until the bottle caps pass through the spiral flipping conveyor in the middle of the conveyor belt 110, so that the bottle caps are flipped 180 degrees, and the bottle caps pass through the bottom of the first inkjet printer 31 for the second inkjet processing;

[0053] Step 4: Finally, the conveyor belt 110 rotates to convey the bottle caps to the other end and discharge them into the collection box 42 through the discharge port 44 and the guide plate 43 for collection.

[0054] The working principle of the present invention is as follows: first, a large number of bottle caps that need to be processed by inkjet coding are poured into the feeding hopper 5, and then the driving motor 19 is started to drive the first driving gear 17 to rotate synchronously through the second driving gear 18 at the bottom, and the second driving gear 18 drives the first driving gear 17 to synchronously drive the two sets of conveyor belts 110 at the bottom to rotate in the opposite direction, and when the conveyor belt 110 rotates, the other end of the conveyor belt 110 will drive the bevel gear 12 to rotate through the first transmission rod 11, and when the bevel gear 12 rotates, it will drive the bevel gear rod 26 meshingly connected on the outer surface to rotate, and when the bevel gear rod 26 rotates, it will synchronously drive the bottle cap conveying rotating block 27 to rotate inside the limiting groove 29, and when the bottle cap conveying rotating block 27 rotates, the wedge-shaped ends at the upper and lower ends will squeeze the first wedge-shaped blocks 28 and the second wedge-shaped blocks 210 on both sides to slide, so in the process of flipping the bottle cap conveying rotating block 27, the bottle caps inside the feeding hopper 5 will be turned over until a bottle cap is stuck downward on the wedge-shaped end of the outer surface of the bottle cap conveying rotating block 27 and will be rotated. The bottle cap conveying rotating block 27 drives the bottle cap to flip downward and fall into the feeding conduit 23. During the flipping process, the bottle cap conveying rotating block 27 will limit the bottle cap inside the top of the limiting groove 29 to prevent the bottle cap from being stuck in the side gap of the limiting groove 29. The outer surfaces of the first wedge block 28 and the second wedge block 210 are both wedge-shaped, the purpose of which is to package the bottle caps to flip normally, and the wedge-shaped ends of the outer surfaces of the bottle cap conveying rotating block 27 also have the same purpose, so that the bottle caps inside the feeding hopper 5 are conveyed to the feeding conduit 23. Inside the conduit 23, the bottle cap will finally drop to the upper surface of the support plate at one end of the two sets of conveyor belts 110, wherein the two sets of conveyor belts 110 push the bottle cap to move through the shifting blocks 14 on the outer surface, and at the same time, the spiral limiting strips 45 will limit the bottle cap on both sides of the conveyor belt 110 to prevent the leather from escaping from the inside of the conveying component 1 during the conveying process. After being transported by the conveyor belt 110, the bottle cap will pass through the bottom of the second inkjet printer 35, and the second inkjet printer 35 will perform the first inkjet processing on the top of the bottle cap;

[0055] At the same time, the conveyor belt 110 will continue to push and convey the bottle caps until the bottle caps pass through the spiral flipping conveyor in the middle of the conveyor belt 110, so that the bottle caps are flipped 180 degrees and then pass through the bottom of the first inkjet printer 31 for the second inkjet printing process. Finally, the conveyor belt 110 rotates to convey the bottle caps to the other end and discharge them downward through the discharge port 44 into the guide plate 43. Then, the bottle caps are conveyed along the guide plate 43 and discharged into the collection box 42 for collection. When the inkjet printing height of the second inkjet printer 35 and the first inkjet printer 31 needs to be adjusted, the threaded rod 3 can be rotated. 7 drives the lifting of the cross frame 34 to achieve the adjustment of the coding height of the second inkjet printer 35 and the first inkjet printer 31. When the collecting box 42 is full of bottle caps, the collecting box 42 in one group can be slowly pulled to move. At the same time, the collecting boxes 42 in other groups will slide down on the upper surface of the inclined guide rail 41 until the first group of collecting boxes 42 is completely detached, so as not to affect the normal coding processing of the bottle caps. Therefore, through the coordinated operation of the conveying component 1 and the unloading component 2, the bottle cap label spraying and coding equipment can perform one-time double-sided coding processing on the bottle caps, thereby improving the production efficiency of the coding processing.

[0056] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
