[0002] As an auxiliary equipment in an important link of the baking production line, the dough cylinder lifting machine is used to lift the dough cylinder filled with dough to a certain height and then flip it to a certain angle, so that the dough slides out of the dough cylinder and enters the funnel of the divider for subsequent operation procedures.

[0003] Current cylinder lifting machines typically use a motor-driven crane for lifting. Because the dough cylinder filled with dough is quite heavy, a speed reducer and a high-power motor are required to meet the lifting requirements, resulting in high installation costs for the drive equipment. For example, Chinese utility model patent application number CN201721064720.X discloses a cylinder lifting machine structure that can achieve left and right cylinder flipping, which uses the above method to drive the lifting. Compared with motor drive, although hydraulic cylinders or pneumatic cylinders have certain advantages in driving costs, they are affected by their stroke limitations and require the use of hydraulic cylinders or pneumatic cylinders with larger strokes, resulting in still high installation costs.

[0004] Therefore, it is necessary to propose a cylinder lifting machine to solve the above problems. Utility Model Content

[0023] 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 the embodiments.

[0024] See also Figure 1-3 As shown, a cylinder lifting machine includes a first-level gantry 3, the inner side of the first-level gantry 3 is provided with a slide 5 driven to rise and fall by a driving mechanism, one side of the slide 5 is rotatably connected to a lifting frame 6, the top of the first-level gantry 3 is fixedly connected to a guide groove 1 for guiding the lifting frame 6 to flip, the driving mechanism includes a lifting cylinder 2 and a second-level gantry 4, the second-level gantry 4 is slidably connected to the first-level gantry 3 in a vertical direction, the slide 5 is slidably connected to the second-level gantry 4 in a vertical direction, the top of the second-level gantry 4 is rotatably connected to a pulley 8, the slide 5 is fixedly connected to a traction rope 9, and the traction rope 9 is fixedly connected to the first-level gantry 3 through the pulley 8.

[0025] When in use, the lifting frame 6 is inserted into the through hole at the bottom end of the cylinder body. At this time, the lifting frame 6 is in a horizontal state, and the lifting cylinder 2 extends to drive the secondary gantry 4 to slide upward. Because the slide 5 is fixedly connected to the traction rope 9, and the traction rope 9 is fixedly connected to the primary gantry 3 through the pulley 8, when the secondary gantry 4 slides upward, the traction rope 9 pulls the slide 5 to slide upward along the secondary gantry 4. The lifting height of the slide 5 is twice the lifting height of the lifting cylinder 2, which makes its cylinder lifting efficiency higher; when the lifting frame 6 moves to the top of the primary gantry 3, the lifting frame 6 drives the cylinder body to flip under the guidance of the guide groove 1 to dump the material in the cylinder body.

[0026] By setting up the lifting cylinder 2, the first-level gantry 3, the second-level gantry 4 and the traction rope 9, with their cooperation, the lifting height of the slide 5 is twice the lifting height of the lifting cylinder 2, so that the lifting efficiency of the slide 5 is higher, and there is no need to set up a lifting cylinder 2 with a longer stroke for driving; in addition, with the cooperation of the first-level gantry 3 and the second-level gantry 4, the lifting of the slide 5 is more stable.

[0027] Specifically, the lifting frame 6 includes an L-shaped arm 12, the middle portion of which is rotatably connected to the slide 5. The end of the L-shaped arm 12 corresponding to the guide slot 1 is rotatably connected to a roller 10, and the position of the slide 5 corresponding to the other end of the L-shaped arm 12 is fixedly connected to a limit plate 13. The rotational connection between the L-shaped arm 12 and the slide 5 is offset from the guide slot 1.

[0028] Specifically, the guide groove 1 is L-shaped, one end of the guide groove 1 is arranged vertically, and the other end of the guide groove 1 extends horizontally to the outside of the secondary gantry 4 .

[0029] When not lifted, one side of the L-shaped arm 12 is supported by the rotating shaft and the other side is supported by the limit plate 13 to keep it in a horizontal state. When the slide 5 moves upward and the roller 10 moves to the guide groove 1, the roller 10 slides along the guide groove 1, thereby driving the lifting frame 6 to flip through the L-shaped arm 12.

[0030] In some embodiments, the inner sides of the primary gantry 3 and the secondary gantry 4 are each provided with a slide groove, and both sides of the secondary gantry 4 and the slide 5 are rotatably connected to guide wheels 11 that are compatible with the slide groove. During the lifting process, the secondary gantry 4 slides along the inner side of the primary gantry 3 via the guide wheels 11, and the slide 5 slides along the inner slide groove of the secondary gantry 4 via the guide wheels 11. The provision of the guide wheels 11 can reduce friction. Preferably, the primary gantry 3 and the secondary gantry 4 each include a column, and the column is a channel steel. Both sides of the secondary gantry 4 and the slide 5 are rotatably connected to multiple guide wheels 11.

[0031] Specifically, a connecting plate 14 is fixedly connected to one side of the first-stage gantry 3. The fixed height of the connecting plate 14 is less than the height of the second-stage gantry 4. The traction rope 9 is fixedly connected to the first-stage gantry 3 through the connecting plate 14. The connecting plate 14 is provided so that the traction rope 9 is connected and fixed to the first-stage gantry 3.

[0032] Specifically, the lifting cylinder 2 is a hydraulic cylinder or a pneumatic cylinder, the cylinder body of the lifting cylinder 2 is connected to the first-stage gantry 3, and the piston rod of the lifting cylinder 2 is connected to the second-stage gantry 4. In order to make the lifting of the first-stage gantry 3 more stable, the bottom end of the first-stage gantry 3 is fixedly connected to a base 7.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
