Description

Technical Field

[0001] The utility model relates to the technical field of packaging, and particularly relates to a synchronous capping machine. Background Art

[0002] During the production and processing of beverages, it is necessary to press-fit bottle caps for sealing. In order to achieve automated production, the prior art usually uses a capping machine to press the bottle cap into the bottle mouth. The existing capping machine generally includes a conveying mechanism and a capping mechanism. The conveying mechanism conveys the container bottles to the lower part of the capping mechanism, and the capping mechanism drives the capping head to press the bottle cap onto the bottle mouth.

[0003] Since the existing capping mechanism can only drive the capping head to move in the vertical direction, the conveying mechanism needs to first convey the container bottles to the lower part of the capping mechanism and then pause, and then wait for the capping mechanism to press the bottle cap onto the bottle mouth, and finally start the conveying mechanism again to convey the container bottles away from the capping mechanism. Since the conveying mechanism needs to start and stop frequently, it will affect the working efficiency and the service life. Summary of the Utility Model

[0004] In order to improve the problem of low working efficiency caused by the frequent start and stop of the existing conveying mechanism, the utility model provides a synchronous capping machine.

[0032] As Figure 1 shown, this embodiment provides a synchronous capping machine, which includes a main frame 10, a conveying mechanism, a support frame 40, a capping mechanism and an electric control component.

[0033] The main frame 10 of this embodiment is used to support the conveying mechanism and the capping mechanism. The main support is preferably in the shape of a cubic frame. The interior of the frame-shaped main frame 10 has a relatively large space to facilitate the accommodation of the components of the capping machine, and is relatively light in weight, which helps to achieve the lightweight of the capping machine. The bottom of the main frame 10 is preferably provided with rollers 11 to facilitate the movement of the capping machine to the required work station. The rollers 11 of this embodiment are also provided with a braking device, and the braking device facilitates the fixed parking of the main frame 10.

[0034] The conveying mechanism of this embodiment includes a chain plate chain 20, a driving sprocket, a driven sprocket and a conveying motor 21. The head and tail of the chain plate chain 20 are connected to form a closed loop. The driving sprocket and the driven sprocket are located inside the loop and tension the chain plate chain 20. The conveying motor 21 is fixedly arranged inside the main frame 10, and the conveying motor 21 is used to drive the driving sprocket to rotate, and the rotating driving sprocket drives the chain plate chain 20 to run.

[0035] The conveying mechanism of this embodiment further includes a support plate 30. The support plate 30 is fixed to the top of the main frame 10 and is distributed in parallel on both sides of the chain plate chain 20. A space is left between the support plates 30 to accommodate the chain plate chain 20. The driving sprocket is rotatably arranged at one end of the support plate 30 through a driving shaft 22, and the driven sprocket is rotatably arranged at the other end of the support plate 30 through a driven shaft 23.

[0036] Both ends of the driving shaft 22 of this embodiment are rotatably connected to the support plate 30 through bearings. The driving sprocket is fixedly sleeved on the driving shaft 22. A transmission gear is further arranged at one end of the driving shaft 22. A transmission chain 24 is arranged on the transmission gear and connected to the output gear on the conveying motor 21, so as to facilitate the driving sprocket to rotate by the conveying motor 21 inside the main frame 10.

[0037] Specifically refer to Figure 2 , corresponding to both ends of the driven shaft 23 of the support plate 30 of this embodiment, a strip-shaped groove 31 and a fixing block 32 are provided. The strip-shaped groove 31 extends along the longitudinal direction of the chain plate chain 20, and the fixing block 32 is arranged at one end of the strip-shaped groove 31 away from the driving shaft 22. The driven sprocket is rotatably sleeved on the driven shaft 23, so that the driven sprocket can rotate. The driven shaft 23 is slidably penetrated through the strip-shaped groove 31. Screw rods 33 are arranged at both ends of the driven shaft 23. The screw rods 33 penetrate and extend out of the fixing block 32. A limit nut 34 is sleeved on the part of the screw rod 33 extending out of the fixing block 32. The limit nut 34 can prevent this end of the screw rod 33 from passing through the fixing block 32. Rotating the limit nut 34 can adjust the position of the driven shaft 23 in the strip-shaped groove 31, so as to change the distance between the driven shaft 23 and the driving shaft 22, and further adjust the tension of the chain plate chain 20 to ensure the reliability of the operation of the chain plate chain 20.

[0038] The conveying mechanism of this embodiment further includes guardrails 25 fixedly arranged on both sides of the chain plate chain 20. The guardrails 25 are fixed on the support plate 30 to prevent the container bottles on the chain plate chain 20 from tipping to both sides and ensure the stability of the container bottles on the conveying mechanism. The surface of the guardrails 25 is covered with a protective sleeve to prevent the surface of the bottle body of the container bottle from being scratched. The material of the protective sleeve of this embodiment is preferably plastic, and its cost is relatively low.

[0039] The support frame 40 of this embodiment is arranged on the top of the main frame 10, and the capping mechanism is arranged on the support frame 40, so that the capping mechanism is suspended above the conveying mechanism. The capping mechanism includes a capping rod 50 and a power component. The bottom of the support frame 40 of this embodiment is fixed to the top of the main support, the top of the support frame 40 is connected to the power component, and the top of the capping rod 50 is connected to the power component, so that the capping rod 50 is suspended above the conveying mechanism. When the conveying mechanism conveys the container bottle through the capping mechanism, the capping mechanism can use the rod part 51 to press the bottle cap tightly onto the bottle mouth.

[0040] Specifically refer to Figure 3The capping rod 50 of this embodiment includes a rod portion 51 and a capping head 52. The rod portion 51 is preferably formed by splicing at least two rod bodies 53. The rod bodies 53 are connected by threads, so that the length of the rod portion 51 can be roughly adjusted and finely adjusted, so that the length of the rod portion 51 meets the capping requirements of container bottles of different models. When the height difference between container bottles of different models is small, the rod portion 51 can be adjusted by fine adjustment, and the length of the rod portion 51 can be adjusted within a smaller range by adjusting the threaded length between the rod bodies 53. When the height difference between containers of different models is large, the rod portion 51 is first adjusted by coarse adjustment, and the number of rod bodies 53 is increased or decreased by disassembling and assembling the rod bodies 53 to adjust the length of the rod portion 51 within a larger range; and then the length of the rod portion 51 is adjusted by fine adjustment to meet the use requirements.

[0041] The rod body 53 of this embodiment is preferably provided with an internal thread hole 54 at one end and an external thread rod 55 at the other end. The external thread rod 55 of one rod body 53 can be inserted into the internal thread hole 54 of another rod body 53, and the internal thread and the external thread can mesh with each other to facilitate the splicing of at least two rod bodies 53.

[0042] The capping head 52 of this embodiment is preferably connected to the bottom of the rod 51 by a thread, and the capping head 52 is connected to the internal thread hole 54 or the external thread rod 55 on the rod body 53, which is convenient for processing and disassembly. The bottom of the disc-shaped capping head 52 has a large area, so that the bottle cap can be pressed onto the bottle mouth. The bottom of the capping head 52 of this embodiment is preferably made of plastic, which can improve the situation that the capping head 52 damages the bottle cap.

[0043] See Figure 4 The power assembly of this embodiment includes a first driving member 60 and a second driving member 61. The first driving member 60 is connected to the top of the capping rod 50 by a thread, and is used to drive the capping rod 50 to move back and forth in the vertical direction, so that the capping rod 50 can achieve the operation of pressing the bottle cap downward. The second driving member 61 is connected to the first driving member 60, and is used to drive the first driving member 60 and the capping rod 50 connected to the first driving member 60 to move back and forth in the horizontal direction. During the capping process, the first driving member 60 has the same conveying direction and conveying speed as the chain plate chain 20, so that the capping rod 50 moves synchronously with the container bottle during the pressing process.

[0044] Since the power assembly of the present embodiment can drive the capping rod 50 to move vertically and horizontally, the capping rod 50 can move synchronously with the container bottle when pressing the bottle cap into the bottle mouth, so that the conveying mechanism does not need to be frequently started and stopped during the process of conveying the container bottle. The conveying mechanism can maintain a constant speed to convey the container bottle through the capping mechanism. The container bottle is not easy to tip over during the capping process, which can effectively improve the capping efficiency and increase the service life of the conveying mechanism.

[0045] Preferably, the number of the gland mechanism and the conveying mechanism in this embodiment is two. A set of cooperating gland mechanism and conveying mechanism is arranged on each side of the support frame 40. The two sets of gland mechanisms and conveying mechanisms can work simultaneously without interference, making the structure of the capping machine compact and improving the working efficiency.

[0046] The power assembly of this embodiment further includes a guide rail 62 and a sliding seat 63. The longitudinal direction of the guide rail 62 is arranged parallel to the longitudinal direction of the conveying chain plate. Preferably, the first driving member 60 in this embodiment is a first air cylinder, and the second driving member 61 is preferably a second air cylinder. The first cylinder body of the first air cylinder is fixedly arranged on the sliding seat 63 to facilitate the first air cylinder to move along the longitudinal direction of the guide rail 62. The first cylinder rod of the first air cylinder is fixedly connected to the top of the gland rod 50. When the first cylinder rod of the first air cylinder extends, the first cylinder rod pushes the gland rod 50 downward to press the bottle cap into the bottle mouth; when the first cylinder rod of the first air cylinder retracts, the first cylinder rod drives the gland rod 50 to move upward to reset the gland rod 50 in the vertical direction.

[0047] The second cylinder body of the second air cylinder in this embodiment is fixed on the support frame 40, and the second cylinder rod of the second air cylinder is fixedly connected to the first cylinder body of the first air cylinder. When the second cylinder rod of the second air cylinder extends, the second cylinder rod pushes the second air cylinder and the gland rod 50 to move synchronously with the container bottle; when the second cylinder rod of the second air cylinder retracts, the second cylinder rod drives the second air cylinder and then the gland rod 50 to reset in the horizontal direction.

[0048] In some embodiments, preferably, the retracting speed of the first cylinder rod is greater than the extending speed, and the retracting speed of the second cylinder rod is greater than the extending speed, so as to shorten the interval time of pressing the bottle cap and thus improve the capping efficiency of the entire capping machine.

[0049] Preferably, the support frame 40 of this embodiment includes two parallel I-shaped frames, and the two I-shaped frames are arranged at intervals along the longitudinal direction of the chain plate chain 20. The guide rail 62 is arranged between the two I-shaped frames, and the two ends of the guide rail 62 are correspondingly connected to the two I-shaped frames, so that the longitudinal direction of the guide rail 62 is parallel to the longitudinal direction of the chain plate chain 20. Preferably, the sliding seat 63 is provided with pulleys 64 connected to the guide rail 62, which can further ensure the smooth movement of the sliding seat 63.

[0050] The electric control component of this embodiment includes a distribution box 70, a controller, and a sensor 71. The distribution box 70 is fixed inside the main frame 10 to distribute electric energy to the components of the capping machine. The controller is installed in the distribution box 70. The sensor 71 is used to detect the position information of the container bottle and feedback it to the controller. The controller controls the operation of the conveying motor 21, the first driving member 60, and the second driving member 61 based on the position information, so that the conveying mechanism cooperates with the capping mechanism to achieve automatic capping. The sensor 71 is preferably a specular reflection type photoelectric sensor 71. The sensor 71 is installed on one side of the chain plate chain 20, and a reflector is installed correspondingly on the other side. When it detects that a container bottle passes by, the sensor 71 can effectively capture the specific position of the container bottle and feedback it to the controller.

[0051] The capping machine of this embodiment further includes an emergency stop button, which is used to control the capping machine to stop in time in case of an emergency to ensure the safety of using the capping machine. It should be noted that before the container bottle passes through the capping mechanism, a bottle cap is placed at the mouth of the container bottle on the conveying mechanism, and at this time, the bottle cap has not been pressed into the mouth of the bottle; when the container bottle passes through the capping mechanism, the capping mechanism will press it into the mouth of the bottle.

[0052] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0053] The above-described embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model should be subject to the appended claims.
