Description

Technical Field

[0001] The utility model relates to the technical field of capping equipment, in particular to an adjustable capping mechanism. Background Technique

[0002] Capping machines play a crucial role in the bottling industry and are an important part of the bottling process. The design features of these machines include adjustable buffer turntables, as well as equipment for tightening and loosening bottle caps after the filling of plastic bottles, glass bottles (molded bottles or tube bottles). Capping machines have a wide range of applications, including but not limited to the pharmaceutical, food, scientific education, and other fields;

[0003] When a traditional capping machine is in use, it is inconvenient to adjust the distance between the capping heads. As a result, the capping machine cannot be applied to caps of different sizes for capping and sealing, which has certain limitations in use. At the same time, there may be a situation where the capping is not in place, affecting the capping and sealing effect of the container. Content of the Utility Model

[0004] The purpose of the utility model is to provide an adjustable capping mechanism to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an adjustable capping mechanism, including a capping machine frame. An elevating lead screw is rotatably installed in the capping machine frame through a bearing. A slide plate is threadedly connected to the elevating lead screw. Two adjusting seats are slidably connected to the slide plate. The tops of the two adjusting seats are fixedly installed with capping motors. The output shafts of the capping motors are fixedly connected with driving gears. Two driven gears are meshed and connected to one side of the driving gears. The bottoms of the two driven gears are fixedly installed with capping shafts. The bottoms of the capping shafts are fixedly installed with capping heads. A pitch lead screw is rotatably installed on one side of the slide plate and at the side position of the adjusting seat through a bearing. The pitch lead screw is a positive and negative threaded lead screw. Slide blocks are threadedly connected to the positive and negative threads of the pitch lead screw. The two slide blocks are respectively fixedly connected to the two adjusting seats.

[0006] Preferably, one ends of the elevating lead screw and the pitch lead screw are both fixedly connected with hand wheels.

[0007] Preferably, guide rods are fixedly installed on both sides of the elevating lead screw and on the capping machine frame.

[0008] Preferably, both sides of the slide plate are sleeved outside the guide rods and are slidably connected to the guide rods.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The capping mechanism of the present utility model is provided with a lifting lead screw. Through the threaded transmission effect of the lifting lead screw, the slide plate can be driven to move. Thus, the capping head below can be driven to move through the movement of the slide plate, so that the working height of the capping head can be freely adjusted. In this way, the capping mechanism of the present utility model can be applied to containers of different heights for capping treatment, reducing the use limitations and improving the scope of application;

[0011] At the same time, the distance between the two capping heads is dynamically adjustable. During actual use, by adjusting the distance, it can be applied to caps of different sizes for rotating work. Through the free adjustment of the distance, the two capping heads can be in full contact with the cap, avoiding capping gaps, having the use effect of stable clamping of the cap, effectively improving the quality and efficiency of capping, avoiding the situation of incomplete capping, and the distance adjustment can be achieved by manual rotation drive, which is convenient to adjust and has good practicability. It can be applied to caps of different sizes for automatic capping treatment, effectively reducing the use limitations and improving the scope of application. Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0018] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "provided with", "connected", etc. shall be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0019] Please refer to Figures 1-3 , an embodiment provided by the present utility model: an adjustable cap screwing mechanism, including a cap screwing machine frame 1, a lifting screw rod 2 is rotatably installed inside the cap screwing machine frame 1, a hand wheel is fixedly connected to the top end of the lifting screw rod 2, guide rods 3 are fixedly installed on both sides of the lifting screw rod 2, a sliding plate 4 is threadedly connected to the lifting screw rod 2, and both sides of the sliding plate 4 are sleeved outside the guide rods 3 and slidably connected to the guide rods 3;

[0020] Furthermore, two adjusting seats 5 are slidably connected to the sliding plate 4, cap screwing motors 6 are fixedly installed at the top ends of the two adjusting seats 5, a driving gear 7 is fixedly connected to the output shaft of the cap screwing motor 6, two driven gears 8 are meshed and connected to one side of the driving gear 7, cap screwing shafts 9 are fixedly installed at the bottom ends of the two driven gears 8, and a cap screwing head 10 is fixedly installed at the bottom end of the cap screwing shaft 9;

[0021] With this structural design, the cap screwing motor 6 can work. When the cap screwing motor 6 works, it drives the driving gear 7 at the bottom end to rotate through its output shaft. When the driving gear 7 rotates, it drives the two driven gears 8 to rotate synchronously. In this way, through the rotation of the two driven gears 8, the cap screwing head 10 is driven to rotate through the cap screwing shaft 9, so as to perform the cap screwing process on the lid of the container by the rotating cap screwing head 10, ensuring the sealing performance of the container;

[0022] In this utility model, a lifting lead screw 2 is provided. The lifting lead screw 2 can be manually rotated driven by a handwheel. When the lifting lead screw 2 rotates, the slide plate 4 threadedly connected thereto will move up and down along the lifting lead screw 2. Thus, the rotating cover head 10 below is driven to move by the movement of the slide plate 4, so that the working height of the rotating cover head 10 can be freely adjusted, thereby enabling the rotating cover mechanism 4 of this utility model to be applicable to containers of different heights for capping treatment, reducing the limitation in use and increasing the applicable range.

[0023] Furthermore, in order to make the rotating cover head 10 of this utility model applicable to clamping and capping work for covers of different sizes, a spacing lead screw 11 is rotatably installed on one side of the slide plate 4 and at the side position of the adjusting seat 5 through a bearing. The spacing lead screw 11 is a positive and negative threaded lead screw. Sliding blocks 12 are threadedly connected to the positive and negative threads of the spacing lead screw 11. The two sliding blocks 12 are respectively fixedly connected to the two adjusting seats 5. One end of the spacing lead screw 11 is fixedly connected to a handwheel.

[0024] With this structural design, the handwheel can be used to manually drive the spacing lead screw 11 to rotate. Since the spacing lead screw 11 is a positive and negative threaded lead screw, when the spacing lead screw 11 rotates, the two sliding blocks 12 threadedly connected thereto will move relatively, that is, move away from each other or approach each other (this effect depends on the forward and reverse rotation of the spacing lead screw 11). When the two sliding blocks 12 move relatively, they will drive the two adjusting seats 5 to move relatively, thereby driving the two groups of rotating cover heads 10 below to move relatively, so as to adjust the spacing between the two groups of rotating cover heads 10. In actual use, by adjusting the spacing, it can be applicable to covers of different sizes for rotating work. Through the free adjustment of the spacing, the two groups of rotating cover heads 10 can be in full contact with the cover, avoiding capping gaps, having the use effect of stable clamping of the cover, effectively improving the quality and efficiency of capping, avoiding the situation of incomplete capping, and the spacing adjustment can be achieved by manual rotation drive, which is convenient to adjust, has good practicability, can be applicable to covers of different sizes for automatic capping treatment, effectively reducing the limitation in use and increasing the applicable range.

[0025] Working principle: When this utility model is in use, a container carrying a cover can be placed between the four rotating cover heads 10. Then, the provided capping motor 6 can work. When the capping motor 6 works, its output shaft drives the driving gear 7 at the bottom to rotate. When the driving gear 7 rotates, it drives the two driven gears 8 to rotate synchronously. Thus, through the rotation of the two driven gears 8, the rotating cover heads 10 are driven to rotate through the capping shafts 9, so as to perform contact capping treatment on the cover of the container to ensure the capping tightness of the container.

[0026] Meanwhile, the cap screwing mechanism of the present utility model is provided with a lifting lead screw 2, which can be manually rotated under the drive of a handwheel. When the lifting lead screw 2 rotates, the sliding plate 4 threadedly connected thereto will move up and down along the lifting lead screw 2. Thus, the movement of the sliding plate 4 drives the cap screwing head 10 below to move, so that the working height of the cap screwing head 10 can be freely adjusted, enabling the cap screwing mechanism of the present utility model to be applicable to containers of different heights for cap screwing treatment, reducing the use limitations and improving the scope of application.

[0027] Moreover, the handwheel is provided to manually drive the spacing lead screw 11 to rotate. Since the spacing lead screw 11 is a positive and negative thread lead screw, when the spacing lead screw 11 rotates, the two sliding blocks 12 threadedly connected thereto will move relatively, that is, move away from each other or approach each other (this effect depends on the forward and reverse rotation of the spacing lead screw 11). When the two sliding blocks 12 move relatively, they will drive the two adjusting seats 5 to move relatively. Thus, the relative displacement of the two groups of cap screwing heads 10 below can be driven by the movement of the two adjusting seats 5, so that the spacing between the two groups of cap screwing heads 10 can be adjusted. In actual use, by adjusting the spacing, it can be applicable to caps of different sizes for rotation work. Through the free adjustment of the spacing, the two groups of cap screwing heads 10 can be in full contact with the cap, avoiding the occurrence of cap screwing gaps, having the use effect of stable clamping of the cap, effectively improving the quality and efficiency of cap screwing, avoiding the situation of incomplete cap screwing, and the spacing adjustment can be achieved by manual rotation drive, which is convenient to adjust, has good practicability, can be applicable to caps of different sizes for automatic cap screwing treatment, effectively reducing the use limitations and improving the scope of application.

[0028] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claims involved.
