Description

Technical Field

[0001] The utility model relates to the field of supporting equipment for filling bags, in particular to a turntable overshoot prevention device. Background Art

[0002] At present, a steering machine that can turn the stick bag 90 degrees is needed in the process of conveying stick line bags. The core device of the steering machine is the turntable, which can rotate around the axis. There are a total of 4 stations, one for every 90 degrees. The stick bag can achieve a 90-degree turn through the turntable, but the stick bag will be thrown out of the turntable due to the centrifugal force during the rotation, resulting in bag jam.

[0003] For example, a Chinese patent with publication number CN103921621B discloses an improvement in the structure of a turntable device for a tire disassembly and assembly machine. The present invention provides an adjustable turntable device for a tire disassembly and assembly machine with more flexible operation. The present invention includes a turntable, and four groups of gripping devices are evenly distributed above the turntable. The gripping devices are arranged in a slideway of the turntable, and the center line of the slideway passes through the center of the turntable; its structural key points are that a synchronous turntable assembly is arranged below the turntable, and the four corners of the synchronous turntable assembly are respectively fastened to the lower ends of the four groups of gripping devices; wherein the lower ends of two relatively groups of gripping devices are connected by a telescopic driving device, and the central vertical axis of the synchronous turntable assembly passes through the center of the turntable.

[0004] In summary, the existing strip bag transport turntable device has many disadvantages, which are summarized as follows:

[0005] ① When the bag is rotating on the turntable, it will be thrown out of the turntable due to the centrifugal force, causing the bag to get stuck;

[0006] ② Placing fixed baffles around the turntable prevents the strip bags from moving in and out freely. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] A turntable overshoot prevention device comprises a turntable 1 and a device body 2. The device body 2 is provided with four groups, and the device body 2 is respectively arranged in a circular array at the bottom of the turntable 1. The device body 2 comprises a rotating arm 21, a return spring 22, a rotating shaft 23, a connecting shaft 24, a plug plate 25, an axis plate connecting seat 26, a pull rod seat 27, and a pneumatic device 28. The turntable 1 is provided with a disk body connecting seat 11 and a slot body 12. The disk body connecting seat 11 is provided below the turntable 1, and the slot body 12 is provided on the turntable 1. One end of the return spring 22 is provided on the turntable 1, and the other end is connected to one side of the rotating arm 21. The middle part of the rotating arm 21 is rotatably connected to the disk body connecting seat 11 through the connecting shaft 24. The rotating shaft 23 is connected to the turntable 1. On the other side of the rotating arm 21, the plug plate 25 is fixed on the rotating shaft 23, and the movable limit is set in the groove body 12. One end of the shaft-plate connecting seat 26 is fixed on the rotating shaft 23, and the other end corresponds to the pull rod seat 27. The pneumatic device 28 is connected to the pull rod seat 27. Two rotating arms 21 are provided in each group of device bodies 2, and are symmetrically arranged and connected through the rotating shaft 23. Two return springs 22 are symmetrically arranged in each group of device bodies 2. The disk body connecting seat 11 is correspondingly arranged on both sides of the connecting shaft 24 in each group of device bodies 2. A limit column 211 is provided above the rotating arm 21, and a limit groove 121 is provided at a position corresponding to the limit column 211 on the turntable 1, and the pneumatic device 28 is a cylinder.

[0023] Four grooves are set on the four 90° workstations of the turntable 1, and then a plug plate 25 that can move up and down and retract is set in the groove body 12. When the strip bag enters the turntable 1 from the front equipment, the plug plate 25 is pulled down by the pull rod seat 27 of the pneumatic device 28 in combination with the shaft plate connecting seat 26, and is lower than the bottom surface of the groove of the turntable 1, so that the strip bag can be pushed in smoothly. After the strip bag is fully in place, the pneumatic device 28 is released, and the plug plate 25 rises to the highest point under the action of the return spring 22. In this way, when the turntable 1 rotates, the strip bag will be blocked by the plug plate 25 and cannot be thrown out if it is thrown by centrifugal force. The limiting groove 121 and the limiting column 211 both play a limiting role.
