Description

Technical Field

[0001] The utility model belongs to the field of automation equipment, and in particular relates to a synchronous belt pitch-changing mechanism. Background Art

[0002] At present, in the process of tablet production, medicine bottles and medicine boxes are used for filling. In order to adjust the coordination efficiency between the filling container and the filling machine, a corresponding variable distance structure is needed to adjust the distance between the medicine bottle and the medicine box. The medicine box is a box for packaging medicines. The advantage is that it saves a lot of time and achieves results as quickly as possible.

[0003] For example, comparative document 1: "CN202122962001.2", a variable wheelbase synchronous belt transmission mechanism, the utility model provides a variable wheelbase synchronous belt transmission mechanism, including: a fixed hub; a movable hub, driven by a driving device to move in a straight line to change the distance between the movable hub and the fixed hub; a connecting piece fixedly mounted on the movable hub; a first idler wheel, rotatably mounted on the connecting piece; a second idler wheel, fixedly mounted relative to the fixed hub, the projection of the first idler wheel in the horizontal plane is located between the second idler wheel and the fixed hub; a synchronous belt, tensioned on the fixed hub, the movable hub, the first idler wheel and the second idler wheel, forming an S-shaped running track to compensate for the displacement change of the synchronous belt as the movable hub moves. The utility model is suitable for chassis dynamometer tests with different wheelbases, and has a simple and compact structure.

[0004] Although the comparative document 1 can move along the motion trajectory, it cannot achieve rapid adjustment during use and takes a long time.

[0005] For example, comparative document 2: "CN202320178873.6", a test needle plate dual-axis non-equidistant automatic pitch-changing mechanism, the present application discloses a test needle plate dual-axis non-equidistant automatic pitch-changing mechanism, which relates to the field of automatic testing technology, including a Y-axis pitch-changing servo motor, an X-axis pitch-changing synchronous belt, a Y-axis pitch-changing shifting mechanism, an X-axis pitch-changing shifting mechanism, a Y-axis pitch-changing synchronous belt, an X-axis pitch-changing servo motor, a Y-axis moving linear bearing, a test probe, a position sensing sheet, a pitch-changing shifting mechanism sensor, a pitch-changing shifting mechanism latch, a pitch-changing fixing rod, an X-axis moving slider, a sliding rod, a connecting rod, a connecting plate and a mounting plate; the Y-axis pitch-changing synchronous belt is arranged and installed on the top side surfaces at opposite ends of the mounting plate, the X-axis pitch-changing synchronous belt is arranged and installed on the top of the front side of the mounting plate and the top of the back side of the mounting plate, the Y-axis pitch-changing shifting mechanism is installed on the bottom side of the mounting plate, and the X-axis pitch-changing shifting mechanism is located on the bottom side of the mounting plate. This test needle plate dual-axis non-equidistant automatic pitch-changing mechanism is novel in design and simple in structure.

[0006] Although Comparative Document 2 can be controlled by a servo motor, it is unable to achieve rapid steering adjustments of components during use, and has limitations.

[0007] For example, comparative document 3: "CN202022146258.6", a synchronous pulley tensioning structure. The utility model relates to a synchronous pulley tensioning structure, including a prime mover, a working machine, an eccentric sleeve, a synchronous pulley, a synchronous belt, a synchronous pulley, a driving shaft, and a driven shaft. The prime mover is connected to the synchronous pulley through the driving shaft, and the working machine is connected to the synchronous pulley through the driven shaft. It is characterized in that the eccentric sleeve is provided with an inner hole, and there is an eccentricity between the inner mounting hole of the eccentric sleeve and the outer circular surface of the eccentric sleeve. The inner mounting hole can be connected to the working machine or the prime mover, and the eccentric sleeve is rotated through the circular hole of the eccentric sleeve to drive the synchronous pulley or the synchronous pulley to rotate, thereby changing the center distance between the synchronous pulleys. The solution of the utility model avoids the phenomenon that the traditional synchronous belt transmission mechanism will have a certain degree of slack after working for a period of time, and ensures the normal operation of the transmission mechanism. It uses a synchronous pulley structure equipped with an eccentric device to realize the adjustment of the center distance and tension of the belt drive, simplifies the synchronous belt transmission mechanism, simplifies the synchronous belt transmission structure, and is easier to operate.

[0008] However, referring to the above patents and prior art, it is known that the existing synchronous belt pitch-changing structure has limitations in that it takes a long time to change the pitch due to its complex structure and it is also unable to adjust the steering of the clamped parts.

[0009] Therefore, in view of the shortcomings of the above-mentioned scheme in actual production and implementation, it has been revised and improved. At the same time, in the spirit and concept of seeking improvement, with the assistance of professional knowledge and experience, and after many ingenuity and experiments, the present utility model was created. A synchronous belt pitch changing mechanism is provided to solve the problem that the existing synchronous belt pitch changing structure has a relatively complex structure during use, which not only takes a long time to change the pitch, but also cannot make steering adjustments to the clamped parts, which has limitations.

[0032] Among them, the mounting part 1 is fixedly connected to the top surface of the mounting plate 7 by high-strength bolts, and the main body of the mounting plate 7 is a rectangular plate structure, and a synchronous belt pitch change component 6 is installed on the top surface of the mounting plate 7. The synchronous belt pitch change component 6 is located on the right side of the mounting part 1, and the driving component 5 is fixedly connected to the top surface of the synchronous belt pitch change component 6, and an output shaft is provided at the front end of the driving component 5.
