Description

Technical Field

[0001] The utility model relates to the technical field of pancake machine auxiliary equipment, in particular to an auxiliary discharging device for a pancake forming machine. Background Art

[0002] Jianbing is a traditional Chinese delicacy. Traditionally, jianbing is made from wheat that's been soaked in water, ground into a paste, and then spread on a griddle into round shapes. While traditionally made with coarse grains, it's now often made with a batter made from fine flour and water. A jianbing machine is a mechanical device used to make jianbing.

[0003] The known authorized patent application number is: CN202123090347.4, which discloses an auxiliary discharging device for a pancake forming machine. Its background technology raises the problem that "a small amount of pancakes are easily adhered to the die surface of the first pressing plate or the die surface of the second pressing plate after baking and forming, which affects the normal production of pancakes". To this end, the technical solution to this problem is "including a mounting frame, which is mounted on the discharging end of the pancake forming machine, and a first air outlet pipe and a second air outlet pipe are provided on the mounting frame. The air outlet end of the first air outlet pipe faces the die surface of the first pressing plate, and the air outlet end of the second air outlet pipe faces the die surface of the second pressing plate. An air supply assembly is provided on the frame, and the air supply assembly is suitable for supplying air to the air inlet end of the first air outlet pipe and the air inlet end of the second air outlet pipe".

[0004] However, during the implementation of the relevant technology, it was discovered that the existing technical solutions had the following problems: In the automated pancake making process, after the pancakes are formed, a discharging device is required to deliver the pancakes into packaging bags for packaging. Currently, the discharging method of existing pancake discharging devices is relatively simple, and most of them deliver the pancakes into the packaging bags via a conveyor belt. However, the existing conveyor belts do not have a unidirectional conveying effect. During the process of conveying the pancakes into the packaging bags and then returning and reversing, the pancakes are easily pulled out of the packaging bags, affecting the accuracy of pancake bagging, thereby reducing the discharging effect and efficiency of the pancakes.

[0042] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] Example 1

[0044] See also Figure 1 - Figure 6 The utility model provides an auxiliary discharging device for a pancake forming machine, comprising: a fixing frame 1;

[0045] A mounting frame 2 is spaced apart from the top of the fixing frame 1, and the mounting frame 2 is reciprocated along the length direction of the fixing frame 1 by a motion mechanism provided on the fixing frame 1;

[0046] A conveyor belt is provided in the mounting frame 2, wherein the conveyor belt includes a driving shaft 4 rotatably connected to one end inside the mounting frame 2;

[0047] An off-stroke gear 5 connected to one end of the driving shaft 4 through a one-way bearing;

[0048] A return gear 6 connected to the other end of the driving shaft 4 through a second one-way bearing and rotating in the opposite direction to the off-wheel gear 5;

[0049] a return rack 7 provided on one side of the fixed frame 1 and meshing with the return gear 6;

[0050] And an off-stroke rack 8 is provided on the other side of the fixed frame 1 and meshed with the off-stroke gear 5 .

[0051] The conveyor belt also includes:

[0052] The tensioning shaft 9 is provided at the other end of the mounting frame 2, and slots are provided on both sides of one end of the mounting frame 2;

[0053] Rolling bearings 10 fixedly connected to both ends of the tensioning shaft 9 and slidably connected to the notches;

[0054] And the conveyor belt 11 connected to the surface of the tensioning shaft 9 and the driving shaft 4 is tensioned together.

[0055] A connecting plate 12 is fixedly installed on one side of the fixed frame 1, and the return rack 7 is fixedly installed on one side of the connecting plate 12. A connecting plate 2 13 is fixedly installed on the other side of the fixed frame 1, and the off-stroke rack 8 is fixedly installed on the top of the connecting plate 2 13. The off-stroke rack 8 and the return rack 7 are arranged parallel to each other.

[0056] The technical solution provided by this embodiment is as follows: when in use, the formed pancake is placed on the conveyor belt 11, and the movement mechanism drives the mounting frame 2 to extend and insert into the packaging bag. At this time, the off-stroke gear 5 rolls on the off-stroke rack 8 and is tightened with the driving shaft 4 under the action of the one-way bearing 1, so that the power input drives the driving shaft 4 to rotate counterclockwise, thereby cooperating with the tensioning shaft 9 to drive the conveyor belt 11 to rotate counterclockwise to transport the pancake into the packaging bag. At the same time, the return gear 6 is loosened from the driving shaft 4 under the action of the one-way bearing 2, so that the return gear 6 moves along the return rack 7. Free rolling; during the return stroke, the process is opposite to the above process, and since the return gear 6 is directly linked to the driving shaft 4 through the one-way bearing 2, during the return stroke, the return gear 6 cooperates with the return rack 7 to drive the driving shaft 4 to maintain a counterclockwise rotation state. Therefore, during the retreat of the conveyor belt 11, the pancakes thereon are still transported unidirectionally into the packaging bag, avoiding the situation where the conveyor belt 11 easily causes the pancakes to deviate and be taken out when retreating, greatly promoting the accuracy and stability of pancake bagging, and effectively improving the discharging effect and efficiency of the pancakes.

[0057] Furthermore, a position detection switch 14 is fixedly mounted on one side of the second connecting plate 13 .

[0058] Specifically, by providing the position detection switch 14 , the controller can conveniently determine the travel limit range of the motion mechanism.

[0059] Furthermore, the motion mechanism includes:

[0060] A slide rail 15 fixedly mounted on the top of the fixing frame 1;

[0061] A slider 16 is slidably engaged with the surface of the slide rail 15;

[0062] The connecting frame 3 is fixedly mounted on the top of the slider 16, and the mounting frame 2 is fixedly connected to the top of the connecting frame 3;

[0063] A motor 17 is fixedly mounted on the bottom of one end of the fixing frame 1, and an output end of the motor 17 movably passes through the fixing frame 1;

[0064] Two synchronous wheels 18 fixedly connected to the output end of the motor 17 and rotatably connected to one side of the top of the fixed frame 1;

[0065] And the synchronous belt 19 connected to the surface of the two synchronous wheels 18 is tensioned and meshed together, and the mounting frame 2 is connected to the synchronous belt 19 through a connecting piece.

[0066] Specifically, when the pancakes are discharged and bagged, the motor 17 drives the synchronous wheel 18 at its output end to rotate back and forth, and the synchronous belt 19 links another synchronous wheel 18 to rotate forward and backward, so that the synchronous belt 19 rotates forward and backward, and then drives the mounting frame 2 and the conveyor belt to move back and forth in a straight line. At the same time, the mounting frame 2 drives the slider 16 to slide back and forth along the surface of the slide rail 15 through the connecting frame 3, ensuring the movement stability of the mounting frame 2, so as to achieve the effect of one-way conveying and discharging of the pancakes, and conveniently conveying the pancakes stably to the deepest part of the packaging bag, preventing the pancakes from deviating and falling out of the packaging bag.

[0067] Example 2

[0069] The regulatory bodies include:

[0070] Two fixing blocks 20 symmetrically fixedly mounted on both sides of one end of the mounting frame 2;

[0071] An adjusting screw 21 threadedly connected to a fixed block 20;

[0072] Two connecting blocks 22 are fixedly mounted on one end surface of the two rolling bearings 10, and one end of the adjusting screw 21 is rotatably connected to a corresponding connecting block 22;

[0073] And a limiting guide rod 23 is slidably connected to the other fixed block 20 , and one end of the limiting guide rod 23 is connected to the corresponding other connecting block 22 .

[0074] The technical solution provided by this embodiment is: when maintaining the conveyor belt 11 in the later stage, the adjusting screw 21 is rotated to make it move on a fixed block 20, and drive the rolling bearing 10 to slide in the groove. At the same time, the rolling bearing 10 drives the limiting guide rod 23 to slide on another fixed block 20, thereby driving the tensioning shaft 9 to move laterally, so as to achieve the purpose of adjusting the tension of the conveyor belt 11, which is convenient for adjusting the tension of the conveyor belt 11 according to needs, and is conducive to improving the flexibility of use.

[0075] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
