Description

Technical Field

[0001] The utility model relates to the technical field of metal baling machine accessories, in particular to an automatic cover locking device for a metal baling machine. Background Art

[0002] Metal balers are common processing equipment used for extrusion and packaging of waste metals. A feed port is provided on the metal baler, and the feed port is used for feeding operations, and a door cover is provided at the feed port. Before the feeding of raw materials is completed and the extrusion and packaging operations are performed, the door cover needs to be closed to ensure that the metal will not be squeezed out from the feed port during the extrusion process. The closing of the door cover requires an automatic locking device, and the extension of the telescopic shaft of the cylinder or hydraulic cylinder in the automatic locking device can drive the door cover to complete the closing operation;

[0003] The utility model patent with the authorization announcement number CN211251457U discloses an automatic locking device for the door cover of a metal baler, including a discharge box, a flip door cover and a telescopic locking assembly; a hydraulic cylinder drives two latch shafts to lock and open the door cover, solving the problems of bulky structure of the door cover self-locking device, difficulty in centering the latch hole and unreliable locking; a hydraulic cylinder is used to drive the two latch shafts to lock and open the door cover, reducing the number of hydraulic cylinders, and a slide seat that meets the rigidity and strength requirements is designed at the position of the support lock rod, and a slide groove is opened on the fixed support seat, so that the piston rod pin shaft moves linearly along the slide groove, thereby driving the latch shaft to accurately insert into the socket; a slide groove is opened on the fixed support seat and a rectangular limit block is welded at the corresponding position of the slide seat, and the two slide relative to each other;

[0004] Although this technical solution has the advantages of preventing one end from tilting due to the force of the piston rod, and reducing the locking force, making the locking process easier, and having good practicality, when this technical solution is used, because the hydraulic cylinder on it is set in an inclined shape, when the telescopic shaft of the hydraulic cylinder is extended to drive the door cover to close, part of the force on the telescopic shaft of the hydraulic cylinder will directly act on the front plate of the discharge box along the direction of the telescopic shaft, causing the front plate to be subjected to a large force. Long-term reciprocating extrusion will cause the front plate to deform to a certain extent, which will affect the normal cooperation between the discharge box and the extrusion plate, affect the packaging operation, and bring inconvenience to the user. In view of this, we propose an automatic cover locking device for metal balers. Utility Model Content

[0021] See also Figure 1-Figure 3 The utility model provides a technical solution: an automatic locking cover device for a metal baler, comprising a discharge box 1, a thickened plate 10 is integrally formed on the rear side of the discharge box 1, and the thickness of the thickened plate 10 is between 10 and 15 cm, so that it has sufficient thickness and is not easily deformed after being compressed;

[0022] Specifically, a support frame 13 is fixedly installed on the front side plate of the discharge box 1, and a door cover 14 is rotatably connected between the left and right side plates of the support frame 13 through a rotating shaft. An end plate 15 is fixedly installed at the end of the door cover 14, and an opening and closing component 2 is arranged on the top plate of the support frame 13. The opening and closing component 2 includes a driving motor 20 fixedly installed on the top plate of the support frame 13, and a horizontally arranged surrounding shaft 21 is fixedly installed at the end of the output shaft of the driving motor 20. A pulling rope 23 is arranged on the surrounding shaft 21, and an end of the pulling rope 23 is fixedly installed on the end of the door cover 14. A fixing ring 151 is fixedly installed on the end plate of the door cover 14, and one end of the pulling rope 23 is fixedly installed on the surrounding shaft 21, and the other end of the pulling rope 23 is fixedly installed on the fixing ring 151, so as to facilitate the opening and closing operation of the door cover 14 by retracting and releasing the pulling rope 23;

[0023] Furthermore, a U-shaped frame 16 is fixedly installed on the top surface of the thickened plate 10, and a locking cover assembly 3 is arranged on the U-shaped frame 16. The locking cover assembly 3 includes a cylinder 30 fixedly installed on the top plate body of the U-shaped frame 16, and a locking plate 32 is arranged on the telescopic axis of the cylinder 30. The locking plate 32 presses the end plate 15 on the thickened plate 10 to complete the locking cover operation. The cylinder 30 is arranged vertically, and after the locking plate 32 presses the end plate 15 on the thickened plate 10, the force is directly directed downward. Since the thickness of the thickened plate 10 is relatively large, it is not easy for the thickened plate 10 to be deformed after the force acts on the thickened plate 10.

[0024] In this embodiment, a base plate 11 is fixedly installed on the rear side of the thickened plate 10, and two inner and outer side support plates 12 for stable support are fixedly installed between the base plate 11 and the thickened plate 10, so as to further provide stable support for the thickened plate 10 and ensure that the thickened plate 10 is not easily deformed after being compressed.

[0025] In addition, a rectangular plate 31 is fixedly installed at the end of the telescopic shaft of the cylinder 30 , and the locking plate 32 is fixedly connected to the rectangular plate 31 by a plurality of fastening bolts, so that the locking plate 32 can be fixedly installed on the telescopic shaft of the cylinder 30 .

[0026] It is worth mentioning that a bearing seat 22 is fixedly installed at the end of the surround shaft 21, the surround shaft 21 is fixedly installed on the inner ring of the bearing in the bearing seat 22, and the bearing seat 22 is fixedly installed on the top surface of the support frame 13, so that the bearing seat 22 can be used to further stabilize the support.

[0027] It is worth noting that the drive motor 20 and the cylinder 30 in this embodiment are both existing conventional technologies and will not be described in detail here.

[0028] When the automatic locking cover device for a metal baler of the utility model is used, the cylinder 30 is started and made to work. When the cylinder 30 works, the telescopic shaft on it is shortened, driving the locking plate 32 to move upward to the corresponding position. At this time, the locking plate 32 no longer presses the end plate 15. Then, the drive motor 20 is connected to the external power supply and made to work. When the drive motor 20 works, the output shaft on it rotates to drive the surrounding shaft 21 to rotate. The surrounding shaft 21 rotates to realize the winding of the pulling rope 23. After the pulling rope 23 is wound, it realizes driving the door cover 14 to open.

[0029] Connect the drive motor 20 to an external power source and make it work. When the drive motor 20 is working, the output shaft thereon rotates in the reverse direction to drive the surrounding shaft 21 to rotate in the reverse direction. The surrounding shaft 21 rotates in the reverse direction to unfold the rolled-up pulling rope 23. After the pulling rope 23 is unfolded, it will rotate in the reverse direction under the action of the door cover 14's own gravity to complete the closing operation. Then start the cylinder 30 and make it work. When the cylinder 30 is working, the telescopic shaft thereon extends to drive the locking plate 32 to press the end plate 15 against the thickened plate 10, completing the locking operation for easy use.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
