Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of baling machines, and in particular relates to a receiving and sending belt wheel supporting frame mechanism of a strapping type baling machine. Background Art
[0002] Automatic balers are increasingly used in the manufacturing industry to automatically pack products after packaging. However, in the current structure of balers, the function of the receiving and sending belt is completed by the pulley installed at the output end of the planetary reducer. Its structure is a cantilever beam, and the force during operation is an alternating load. When the baler is used in continuous operation, the output end shaft, bearings and gears of the planetary reducer will be excessively worn or broken due to the large alternating load, causing the reducer to fail or even be scrapped.
[0003] Currently, most applications are Figure 1 , Figure 2 Two types of receiving and conveying belt structures.
[0004] Figure 1 The middle motor 1 is coaxially installed with the first planetary reduction box 2 and fixed on the chassis; the first receiving and sending pulley 3 is installed on the output shaft 4 of the first planetary reduction box.
[0005] Figure 2 The second planetary reduction box 5 is also fixed on the chassis, and a second receiving and sending pulley 6 is installed on its output end; Figure 1 The difference is that the pulley is larger, and the strapping belt is pressed tightly on the pulley by a chain pressure pulley.
[0006] The two strapping balers mentioned above use a large radial force to press the strapping belt against the strapping belt wheel to generate a tightening force by friction when strapping and tightening the strapping belt. Therefore, this radial force is large and even exceeds the radial force load of the output shaft of the reducer. In the case of short-term intermittent work, the trouble-free working time of the reducer is acceptable; when used in the case of long-term continuous work, the trouble-free working time of the reducer cannot meet the use requirements. Summary of the invention
[0007] The purpose of the present invention is to solve the problem that the planetary reduction box inside the existing baler has a short life when the baler is used in continuous operation, and to provide a support frame for the sending and receiving pulley of the strapping baler.
[0008] The technical solution of the present invention is: a support frame for the sending and receiving pulley of a strapping baler, characterized in that: it includes a shaft end bracket and a reducer output extension shaft; the shaft end bracket and the planetary reducer are installed and fixed on the same chassis; one end of the reducer output extension shaft is coaxially fixedly connected to the output shaft of the planetary reducer, and the other end is rotatably installed on the shaft end bracket.
[0009] The other end of the output extension shaft of the reducer in the technical solution of the present invention is mounted on the shaft end bracket through a bearing, and can rotate freely in the circumference but is supported by the shaft end bracket in the radial direction.

[0012] The shaft end bracket described in the technical solution of the present invention is composed of a second supporting block and a second supporting plate. The second supporting block is a column and is installed and fixed on the same chassis as the second planetary reducer; the second supporting plate is plate-shaped and is vertically fixed on the second supporting block; the reducer output extension shaft is a second reducer output extension shaft, one end of which is coaxially fixedly connected to the output end of the second planetary reducer, and the other end is installed on the second supporting plate through a second bearing and is radially supported.

[0014] The shaft end bracket described in the technical solution of the present invention is composed of a third support block, a fourth support block and a third support plate; the third support block and the fourth support block are both cylinders, which are installed and fixed on the same chassis as the second planetary reducer, and are distributed on both sides of the second receiving and sending pulley; the third support plate is plate-shaped, and is vertically fixed on the third support block and the fourth support block; the reducer output extension shaft is also the second reducer output extension shaft, one end of which is coaxially fixedly connected to the output end of the reducer of the second planetary reducer, and the other end is also installed in the middle of the third support plate using a second bearing for radial support.

[0016] The invention has the characteristics of simple structure, can avoid excessive wear or fracture failure of the reducer and can extend the service life of the planetary reducer, and is mainly used for using the baler under continuous working conditions. BRIEF DESCRIPTION OF THE DRAWINGS

One end of the second reducer output extension shaft 15 is coaxially fixedly connected to the output end of the second planetary reducer 5, and the other end is mounted on the second support plate 13 through the second bearing 14 for radial support.
[0032] This embodiment 3 is aimed at Figure 2 An improved structural support frame is proposed for the receiving and sending pulley structure, and its working principle is the same as that of embodiment 1.
[0033] Example 4 Reference Figure 8 An integral support frame for a receiving and sending pulley of a strapping baler includes a second bearing 14, a second reducer output extension shaft 15, and a second shaft end bracket 16. The second shaft end bracket 16 is an integral shaft end bracket consisting of an arc-shaped side column portion and a laterally extending plate-shaped end portion.
