Description

Technical Field

[0001] The utility model relates to the technical field of dividers, in particular to a divider with stable operation. Background Art

[0002] The superficial meaning of a divider can be roughly understood as a mechanism that can divide an object into several sections or pieces.

[0003] Existing dividers usually use indexing cams and roller discs to achieve intermittent motion. The cam rotates, and the track on the cam pushes the column under the roller disc, causing the roller disc to rotate intermittently. However, the track-driven method not only has poor rotation precision, but is also extremely unstable. In order for the track to smoothly push the column and get stuck, the gap between the track and the column must be larger, which will lead to a reduction in precision between the two and a reduction in the limit position of the column, causing the roller disc to easily rotate back and forth. In particular, if the material on the roller disc is slightly heavier, the inertia of the back and forth rotation will be greater, making it difficult to run smoothly.

[0004] Based on the above background, a smoothly running segmenter is proposed to solve the proposed problem. Utility Model Content

[0005] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by implementing the utility model. The purpose and other advantages of the utility model can be realized and obtained through the structures specifically pointed out in the description and other drawings of the description.

[0006] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a divider with stable operation.

[0007] To achieve the above-mentioned purpose, the technical solution of the utility model is: a smoothly running divider, including: a housing, a worm, an input shaft, a turbine, and an output shaft, the worm being rotatably arranged in the housing; the input shaft being installed in the housing; the turbine and the worm being clearance-matched and arranged on the turbine; the output shaft being installed in the housing; the intermittent transmission assembly including a driving wheel and a driven wheel, the driving wheel being installed on the input shaft and fixedly connected to the turbine, the driven wheel being installed on the output shaft, the gear teeth on the driving wheel being divided into sixteen equal parts and four of the teeth being merged into one tooth, the gear teeth on the driven wheel being divided into twenty-six equal parts and two of the teeth being symmetrical at one hundred and eighty degrees being merged into one tooth respectively.

[0008] Preferably, the diameter of the driving wheel is smaller than that of the driven wheel.

[0009] Preferably, the outward protrusion length of one combined tooth on the driving wheel is smaller than that of the remaining twelve teeth.

[0010] Preferably, the end faces of each tooth on the driven wheel are both recessed inwards.

[0011] Preferably, the driving wheel is fixedly connected to the turbine via a plurality of locking members.

[0012] Preferably, the locking member adopts a bolt structure.

[0013] Preferably, the gear teeth on the driving wheel and the gear teeth on the driven wheel are clearance-matched.

[0014] Preferably, a flange is installed on one side of the shell.

[0015] Preferably, a motor is arranged on the flange.

[0016] Preferably, the motor is connected to a worm gear.

[0017] By adopting the above technical scheme, the beneficial effect of the utility model is as follows: the intermittent mode of the utility model drives the turbine to rotate through the worm, so that the driving wheel drives the driven wheel to rotate, and the roller disk rotates. When it rotates to the point where the driving wheel is combined with one tooth and faces the point where the driven wheel is combined with one tooth, the push on the driven wheel is cancelled, and the driven wheel stops rotating, that is, self-locking. The driving wheel continues to rotate, and when the gear teeth touch the point where the driven wheel is combined with one tooth, it is pushed to rotate again, thereby realizing the self-locking of the output shaft and enabling it to move intermittently. The divider is through the gear teeth and the combined teeth between the two gears, and the matching precision between the gear teeth will be improved, and the limit of the roller disk is also improved, so that the intermittent rotation of the roller disk is more stable, and the noise generated by the rotation between the gears is also small, and the service life is longer. It can be widely used in the fields of automated production line packaging, printing, ceramic machinery, etc. that require intermittent action, and through the number of gear teeth and the number of combined teeth of the driving wheel and the driven wheel, when the driving gear rotates one circle, the driven gear just rotates half a circle with the output shaft, which is more suitable for objects that are required on both the front and back sides.

[0018] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure.

[0029] The following will describe the implementation methods of the present invention in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. It should be noted that as long as there is no conflict, the various embodiments of the present invention and the various features in the embodiments can be combined with each other, and the technical solutions formed are all within the protection scope of the present invention.

[0030] Meanwhile, in the following description, many specific details are set forth for the purpose of explanation to provide a thorough understanding of the embodiments of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without the specific details or the specific manner described herein.

[0031] See also Figure 1-4The utility model provides a smoothly running divider, including: a housing 1, a worm 2, an input shaft 3, a turbine 4, and an output shaft 5, wherein the worm 2 is rotatably arranged in the housing 1; the input shaft 3 is installed in the housing 1; the turbine 4 is clearance-matched with the worm 2 and is arranged on the turbine 4; the output shaft 5 is installed in the housing 1; an intermittent transmission component 6, which includes a driving wheel 61 and a driven wheel 62, the driving wheel 61 is installed on the input shaft 3 and is fixedly connected to the turbine 4, the driven wheel 62 is installed on the output shaft 5, the gear teeth on the driving wheel 61 are divided into sixteen equal parts and four teeth are merged into one tooth, and the gear teeth on the driven wheel 62 are divided into twenty-six equal parts and two teeth symmetrical at one hundred and eighty degrees are respectively merged into one tooth.

[0032] When in use, the roller disc is connected to the output shaft 5. When intermittent rotation is required, the worm 2 is rotated, the turbine 4 is mechanically rotated, and the driving wheel 61 is rotated with the input shaft 3. When the gear teeth of the driving wheel 61 are meshed with the gear teeth of the driven wheel 62, the driving wheel 61 will drive the driven wheel 62 to rotate together, so that the output shaft 5 rotates with the roller disc. When it rotates to the point where the driving wheel 61 is connected with one tooth and faces the point where the driven wheel 62 is connected with one tooth, the push on the driven wheel 62 is cancelled, and the driven wheel 62 stops rotating, that is, self-locking. The driving wheel 61 continues to rotate, and when the gear teeth touch the point where the driven wheel 62 is connected with one tooth, it is pushed to rotate again, thereby realizing the self-locking of the output shaft 5 and enabling it to move intermittently. Among them, through the number of teeth and the number of teeth of the driving wheel 61 and the driven wheel 62, when the driving gear 61 rotates one circle, the driven gear 62 just rotates half a circle with the output shaft 5, which is more suitable for objects that need to be on both the front and back sides.

[0033] According to some embodiments of the present application, optionally, the diameter of the driving wheel 61 is smaller than that of the driven wheel 62. This has the effect of achieving different numbers of rotations of the two wheels, thereby achieving intermittent motion.

[0034] According to some embodiments of the present application, optionally, the length of the combined tooth on the driving wheel 61 protruding outward is less than the remaining twelve teeth, which prevents the combined tooth on the driving wheel 61 from protruding outward too much and increasing the distance with the driven wheel 62, so that the gear teeth cannot be smoothly pushed to the position where the driven wheel 62 is combined into one tooth.

[0035] According to some embodiments of the present application, optionally, the end faces of the passive wheel 62 that are connected to one tooth are all recessed inwards, which has the function of preventing the active wheel 61 from rotating at the end that is connected to one tooth.

[0036] According to some embodiments of the present application, optionally, the driving wheel 61 is fixedly connected to the turbine 4 via a plurality of locking members 7 .

[0037] According to some embodiments of the present application, the locking member 7 is optionally a bolt structure, which has the advantages of low cost and simple and easy-to-understand locking operation.

[0038] According to some embodiments of the present application, the gear teeth on the driving wheel 61 and the gear teeth on the driven wheel 62 are optionally matched with each other, so that the two wheels can be driven by each other at the same time.

[0039] According to some embodiments of the present application, optionally, a flange 8 is installed on one side of the housing 1, and a motor is arranged on the flange 8, and the motor is drivingly connected with the worm 2. This has the function of stabilizing the operation of the motor and the rotation of the worm 2.

[0040] According to some embodiments of the present application, optionally, when the shell 1 is manufactured, the mold is opened in half, which is not only easier to process, but also both shells 1 manufactured by the mold opened in half can be used, without wasting materials and saving costs.
