Description

Technical Field

[0001] The present application relates to the field of screen printing equipment, and in particular to a split roller conveyor belt capping system. Background Art

[0002] After the bottle is formed, it needs to go through the processes of silk screen printing and capping. Silk screen printing is the process of printing text, patterns, or other logos on the bottle cap and bottle body using a silk screen printer. Capping is the process of screwing the cap onto the end of the bottle using a capping machine.

[0003] In the prior art, a capping mechanism for bottle tools can be found in patent publication CN 112194076 A, which discloses a capping mechanism for a vacuum capping machine and its operating method. The capping mechanism comprises a drive mechanism, a capping mechanism, a bottle clamping mechanism, and a vacuum generating mechanism. The capping mechanism includes an upper support plate, an upper middle support plate, a lower middle support plate, and N capping assemblies arranged in parallel and spaced order from top to bottom. The bottle clamping assemblies include a bottle clamping motor, a bottle clamping claw, and an ampoule platform. The inner sides of the multiple ampoule platforms are connected to the cam drive surface cam pair of the lower drive cam. The vacuum generating mechanism includes N vacuum generators and N vacuum covers. The N vacuum covers are correspondingly mounted on the outer sides of N capping heads. The N vacuum generators are fixed above the upper support plate and connected to the inner cavities of the N vacuum covers via N vacuum tubes. This invention has the technical advantage of high production efficiency.

[0004] Regarding the above-mentioned related technologies, the capping machine is large in size and requires a separate production workshop. As a result, the bottles need to be transferred to the capping machine workshop after screen printing, which takes up a lot of production time and has an adverse impact on production efficiency. Summary of the Invention

[0005] In order to improve the efficiency of bottle capping, the present application provides a split roller conveyor belt capping system.

[0006] The present application provides a split roller conveyor belt capping system that adopts the following technical solutions:

[0007] A split roller conveyor belt capping system includes a frame, a bottle cap conveying assembly and a bottle pushing assembly;

[0008] The frame is equipped with a bottle conveyor belt, and the input end of the bottle conveyor belt is connected to the output end of the screen printing machine;

[0009] The bottle cap conveying assembly is used to convey the bottle caps to the bottle conveyor belt;

[0010] The bottle pushing assembly is used to move the bottle mouth of the bottle close to the bottle cap in the horizontal direction;

[0011] The split roller conveyor belt capping system further comprises a fixing assembly and a capping assembly, wherein the fixing assembly is used to fix the bottle;

[0012] The capping assembly includes a capping seat, a capping connecting rod and a capping wheel. The capping seat is mounted on the frame, the capping connecting rod is rotatably engaged with the capping seat, and the capping wheel is rotatably engaged with the capping connecting rod.

[0013] The capping seat is provided with a connecting rod driving part and a wheel driving part. The connecting rod driving part is used to drive the capping connecting rod to rotate toward or away from the bottle cap, and the wheel driving part is used to drive the capping wheel to rotate.

[0014] By adopting this technical solution, bottles are first transferred from the screen printer to the bottle conveyor, where a bottle pusher pushes the bottles into the bottle caps. Then, a fixing assembly secures the bottles, and the capping wheel presses against the bottle caps and rotates, threading the caps into the bottles and completing the capping process. This reduces bottle transfer time and improves capping efficiency.

[0015] Optionally, the connecting rod driving member is linearly abutted against one end of the cap screwing rod, and the cap screwing seat is provided with an elastic reset member, which is abutted against the other end of the cap screwing rod.

[0016] By adopting the above technical solution, the connecting rod driving member moves away from the capping connecting rod, allowing the capping connecting rod to be tightly fitted against the bottle cap under the action of the elastic return member, thereby completing the capping. After the capping is completed, the connecting rod driving member overcomes the elasticity of the elastic return member and drives the capping connecting rod to rotate, causing the capping wheel to move away from the bottle cap and bottle, thereby allowing the capped bottle to continue to move along the bottle conveyor belt.

[0017] Optionally, the connecting rod driving member is a cylinder, the connecting rod driving member is fixedly mounted on the rotary cover seat, and the connecting rod driving member abuts against the rotary cover connecting rod via an abutment rod.

[0018] By adopting the above technical solution, the connecting rod driving part has a simple structure and a fast response speed, which is beneficial to reducing the volume of the split roller conveyor belt capping system and ensuring the capping efficiency.

[0019] Optionally, the rotary cover seat is rotatably coupled with a transmission synchronous wheel, the rotary cover wheel is equipped with a wheel body synchronous wheel, the transmission synchronous wheel is connected to the wheel body synchronous wheel through a synchronous belt, and the wheel body driving member drives the rotary cover wheel to rotate through the transmission synchronous wheel.

[0020] By adopting the above technical solution, the wheel driving member drives the capping wheel to rotate through the transmission synchronous wheel and the first synchronous belt, so that the installation position of the wheel driving member is not easily affected by the rotation of the capping connecting rod, thereby facilitating the layout of the split roller conveyor belt capping system to take into account both functional requirements and volume requirements.

[0021] Optionally, the wheel driving member is a motor, the wheel driving member is mounted on the rotary cover seat, and an active synchronous wheel is mounted on the output shaft of the wheel driving member;

[0022] The rotary cover seat is equipped with a rotary damper, the core shaft of the rotary damper is equipped with a driven synchronous wheel, the active synchronous wheel is connected to the driven synchronous wheel through a synchronous belt, and the transmission synchronous wheel is equipped with the core shaft of the rotary damper.

[0023] By adopting the above technical solution, the rotary damper adjusts the torque of the capping wheel. After the capping wheel and the bottle cap are properly tightened, relative movement between the capping wheel and the bottle cap will not easily occur due to the action of the rotary damper, thereby protecting the bottle cap from friction and scratches.

[0024] Optionally, the bottle cap conveying assembly includes a vibration plate and a guide rail, the vibration plate is used to convey the bottle caps, the guide rail is connected to the output end of the vibration plate, and the guide rail is curved.

[0025] By adopting the above technical solution, after the bottle cap is output from the vibration plate to the guide rail, it is turned over by the guide rail and the opening of the bottle cap is directed toward the bottle. The structure is simple, reliable and compact.

[0026] Optionally, the frame is provided with a guide surface, which is arranged straight in the horizontal direction. The frame is installed with a limit plate, which is used to make the bottom of the bottle fit tightly against the guide surface. The limit plate is arranged closer to the input end of the bottle conveyor belt than the bottle pushing assembly.

[0027] By adopting the above technical solution, the bottles can be neatly transported to the bottle pushing assembly, so that the bottles can be accurately inserted into the bottle caps.

[0028] Optionally, the fixing assembly includes a vertical fixing block and a vertical driving member, the vertical fixing block is located on the top of the bottle conveyor belt, and the vertical driving member is used to drive the vertical fixing block to move toward or away from the bottle in a vertical direction.

[0029] By adopting the above technical solution, the vertical fixing block presses against the bottle from the top, so that the bottle is fixed to the bottle conveyor belt, and the structure is simple, reliable and compact.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. First, bottles are transferred from the screen printer to the bottle conveyor belt, where a bottle pusher pushes the bottles into the caps. Then, a fixing assembly secures the bottles, and the capping wheel presses against the caps and rotates, threading the caps into the bottles and completing the capping process. This reduces bottle transfer time and improves capping efficiency.

[0032] 2. The connecting rod driving member moves away from the capping connecting rod, so that the capping connecting rod is pressed against the bottle cap under the action of the elastic return member, thus completing the capping. After the capping is completed, the connecting rod driving member overcomes the elasticity of the elastic return member and drives the capping connecting rod to rotate, so that the capping wheel moves away from the bottle cap and the bottle, so that the capped bottle continues to move along the bottle conveyor belt;

[0033] 3. The wheel driving member drives the capping wheel to rotate through the transmission synchronous wheel and the first synchronous belt, so that the installation position of the wheel driving member is not easily affected by the rotation of the capping connecting rod, thereby facilitating the layout of the split roller conveyor belt capping system to take into account both functional requirements and volume requirements.

[0040] The following is combined with Figure 1-5 This application is described in further detail.

[0041] The embodiment of the present application discloses a split roller conveyor belt capping system. Figure 1The split roller conveyor capping system is located at the output end of the screen printing machine. In this embodiment, the bottles are centrifuge tubes. The split roller conveyor capping system includes a frame 1, a bottle cap conveying assembly 2, a bottle pushing assembly 3, a fixing assembly 4, and a capping assembly 5.

[0042] The frame 1 is equipped with a bottle conveyor belt 11, which includes a sprocket, a chain and a conveyor roller. The sprockets are rotatably coupled to the frame 1, the chains are wound around the sprockets, the conveyor rollers are rotatably coupled to the chains, and the sprockets are driven by a motor, thereby driving the conveyor rollers to move in a horizontal direction, and making the conveyor rollers rotate in conjunction with the bottles during the capping process to reduce friction during the capping process.

[0043] Reference Figure 2 The frame 1 is provided with two guide surfaces 101, which are arranged opposite each other and are both arranged horizontally and straight. A limit plate 12 is fixedly mounted on the frame 1, and the limit plate 12 is provided with a limit bevel. The limit bevel extends horizontally and is inclined from one side of the frame 1 toward the other side of the frame 1. The limit bevel makes the limit plate 12 trapezoidal in shape. After the bottles move horizontally along the bottle conveyor belt 11 to the position where the limit plate 12 is located, the bottle mouths of the bottles abut against the limit bevels, so that the bottoms of the bottles fit tightly against the guide surfaces 101, so that the bottles are neatly arranged along the guide surfaces 101, thereby ensuring accuracy when the bottles are subsequently inserted into the openings of the bottle caps.

[0044] Reference Figure 1 and Figure 2 The bottle cap conveying assembly 2 is located on one side of the bottle conveyor belt 11, and the bottle cap conveying assembly 2 includes a vibration plate 21 and a guide rail 22. The vibration plate 21 is used to convey the bottle caps, and when the bottle caps are output from the output end of the vibration plate 21, the opening of the bottle caps is set vertically upward. The guide rail 22 is fixedly mounted on the frame 1, and the input end of the guide rail 22 is connected to the output end of the vibration plate 21. The guide rail 22 is curved, and the shape of the guide rail 22 is approximately parabolic, so that the opening of the bottle cap gradually rotates from the vertical upward state to the horizontal state after entering the guide rail 22, so as to facilitate the subsequent insertion of the bottle into the opening of the bottle cap. In addition, an opening and closing cylinder 221 is fixedly installed at the bottom of the guide rail 22, and an opening and closing plate is fixedly installed on the output rod of the opening and closing cylinder 221. When the output rod of the opening and closing cylinder 221 is in an extended state, the opening and closing plate closes the output end of the guide rail 22. When the output rod of the opening and closing cylinder 221 is in a retracted state, the opening and closing plate opens the output end of the guide rail 22, so that the bottle caps fall to the bottle conveyor belt 11 in an orderly manner.

[0045] The bottle pushing assembly 3 includes a push drive 31 and a push plate 32. The push drive 31 is used to drive the push plate 32 horizontally toward the bottle cap, thereby causing the bottle mouth to horizontally approach the bottle cap through the push plate 32 and inserting the bottle into the bottle cap. Specifically, in the embodiment of the present application, the push drive 31 is a cylinder type, the push drive 31 is fixedly mounted on the frame 1, and the output rod of the push drive 31 is horizontally oriented toward the guide rail 22. The push plate 32 is circular and fixedly mounted on the output rod of the push drive 31. Therefore, the push plate 32 is moved closer to or away from the guide rail 22 by the extension and contraction of the output rod of the push drive 31.

[0046] Reference Figure 2 The fixing assembly 4 includes a vertical fixing block 41 and a vertical driving member 42. The vertical fixing block 41 is located at the top of the bottle conveyor belt 11. The vertical driving member 42 is used to drive the vertical fixing block 41 to move vertically toward or away from the bottles, thereby pressing the bottles against the bottle conveyor belt 11. Specifically, in the embodiment of the present application, the vertical driving member 42 is a cylinder, fixedly mounted on the frame 1, and the output rod of the vertical driving member 42 is arranged vertically downward. The top of the vertical fixing block 41 is fixedly mounted to the output rod of the vertical driving member 42, and the bottom of the vertical fixing block 41 is provided with a fixing groove. The shape of the fixing groove is adapted to the outer shape of the bottle. When the bottle is fixed, the inner wall of the fixing groove presses against the outer circumference of the bottle, thereby stably fixing the bottle to the top of the bottle conveyor belt 11.

[0047] Reference Figure 3 and Figure 4 The capping assembly 5 is located opposite the fixed assembly 4 and includes a capping base 51, a capping connecting rod 52, and a capping wheel 53. The capping base 51 is fixedly mounted on the frame 1. A rotary damper 511 is fixedly mounted on the capping base 51. The core shaft of the rotary damper 511 is rotatably mounted on the capping base 51. The middle portion of the capping connecting rod 52 is rotatably engaged with the core shaft of the capping base 51 via a bearing. The outer peripheral surface of the capping wheel 53 is made of rubber and is rotatably engaged with one end of the capping connecting rod 52.

[0048] The capping base 51 is provided with a connecting rod drive 512 and an elastic return member 513. The connecting rod drive 512 is a pneumatic cylinder and is fixedly mounted on the capping base 51, with its output shaft vertically downwardly arranged. The output shaft of the connecting rod drive 512 is fixedly mounted with an abutment rod 54, which abuts and fits against the other end of the capping connecting rod 52. This allows the connecting rod drive 512 to extend or retract its own output rod, thereby driving the capping wheel 53 at the other end of the capping connecting rod 52 away from or toward the bottle cap. The elastic return member 513 is elastic, and its bottom also abuts and fits against the other end of the capping connecting rod 52. Therefore, when the connecting rod drive 512 retracts, the elastic return member 513 causes the capping wheel 53 to abut and fit tightly against the bottle cap. Specifically, in the embodiment of the present application, the elastic return member 513 includes a telescopic sleeve and a telescopic pin. The telescopic pin slides in the vertical direction to fit in the telescopic sleeve, and a linear spring (not shown in the figure) is provided between the telescopic pin and the telescopic sleeve so that the linear spring can quickly rebound the telescopic pin after retraction to push the rotary cover connecting rod 52 to rotate.

[0049] Reference Figure 4 and Figure 5 The rotary cover base 51 is provided with a wheel drive 514, which is a motor. The wheel drive 514 is fixedly mounted on the rotary cover base 51, and the output shaft of the wheel drive 514 is arranged horizontally. A driving synchronous pulley 55 is coaxially fixedly mounted on the output shaft of the wheel drive 514. A driven synchronous pulley 56 is coaxially fixedly mounted on the core shaft of the rotary damper 511. The driving synchronous pulley 55 is connected to the driven synchronous pulley via a timing belt (not shown in the figure), so that the wheel drive 514 drives the core shaft of the rotary damper 511 to rotate via the driving synchronous pulley 55 and the driven synchronous pulley 56. A transmission synchronous wheel (not shown in the figure) is coaxially fixedly mounted on the core shaft of the rotary damper 511, and a wheel body synchronous wheel 57 is coaxially fixedly mounted on the capping wheel 53. The transmission synchronous wheel is connected to the wheel body synchronous wheel 57 through a synchronous belt (not shown in the figure), so that the wheel body driving member 514 drives the capping wheel 53 to rotate through the active synchronous wheel 55, the passive synchronous wheel 56, the transmission synchronous wheel, the wheel body synchronous wheel 57 and the two synchronous belts.

[0050] The operating principle of the split roller conveyor capping system of the present embodiment is as follows: First, after being output from the screen printer, the bottles are transferred to the bottle conveyor belt 11, where they move horizontally along the bottle conveyor belt 11. The bottle caps drop from the output port at the bottom of the guide rail 22 to the top of the bottle conveyor belt 11, where the bottle pusher pushes the bottles horizontally to insert them into the bottle caps. Next, the vertical fixing block 41 moves vertically downward to secure the bottles to the bottle conveyor belt 11. Next, the connecting rod driving member 512 retracts upward, causing the capping connecting rod 52 to rotate toward the bottle caps under the combined action of gravity and the elastic return member 513. This in turn causes the capping wheel 53 to press against the bottle caps and rotate, allowing the bottle caps to be screwed into the bottles and capping to be completed. This reduces the bottle transfer time and improves the bottle capping efficiency.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
