Description

Technical Field

[0001] The invention relates to a food processing machine, in particular to a pancake forming and arranging integrated machine. Background Art

[0002] Currently, the forming machines on the market that make mooncakes weighing 1 to 5 kilograms are only capable of forming single mooncake patterns, and most of the plates are moved to the racks manually.

[0003] The existing mooncake forming machine on the market is a flip-type pancake making machine, whose working principle is that the machine mold shell is fixed, and the chip in the mold moves to press the mooncake pattern. The other is a straight punching type pancake making machine, in which the machine mold shell presses down to form, and the chip in the mold squeezes the mooncake. There are the following shortcomings:

[0004] 1. For the current largest amount of mooncakes with five-nut fillings, the pressure during making the mooncakes is too small, and the patterns on the mooncakes are not clear.

[0005] 2. If the pounding pressure is too high, the mooncake skin will drill into the pores of the mold. After the mooncake is formed, small nail-shaped skin will appear on the pattern (commonly known as nailing). The produced mooncakes have a very hard taste, and the mooncakes are easily pressed out of the skirt when they are formed. The steps are cumbersome and the effect is very unsatisfactory.

[0006] 3. The production efficiency is 2kg to 6kg per minute (2 to 6 moon cakes) for 2-jin cakes, and 5kg to 15kg per minute (2 to 6 moon cakes) for 5-jin cakes. The cake making speed is slow.

[0007] In summary, it is difficult for traditional mooncake forming machines to strike a balance between the clarity of the pattern and the softness of the filling, and their production efficiency is low. For large factories with a daily production task of more than 100,000 kilograms, it is difficult to keep up with the production rhythm. Summary of the invention

[0008] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to propose a large pancake forming and arranging machine with clear patterns, moderate hardness, good taste and high operating efficiency.

[0009] The pancake forming and arranging machine can solve the above technical problems, and its technical solution includes a material pushing mold device, a pancake beating device, a plate transferring device and a plate arranging device, wherein:

[0010] 1. The pusher mold device includes a loading mold and a pusher cylinder. The loading mold is installed on a linear guide rail, and the pusher cylinder drives the loading mold backward into the cake-making position.

[0011] 2. The cake-making device includes a forming mold that is arranged at the cake-making position and is combined with the loading mold to press the large cake. At the mold opening position of the loading mold and the forming mold, the pushing cylinder drives the loading mold to move forward out of the cake-making position to the loading position.

[0012] 3. The plate arranging device includes a lifting mechanism which is arranged behind the cake-making position and vertically arranges and stores the cake-receiving plates. The lifting mechanism transports the cake-receiving plates upward in a stepping manner, and the stepping distance is equal to the spacing between adjacent cake-receiving plates. At the stop position of each step, there is an empty cake-receiving plate aligned with the cake-making position.

[0013] 4. The plate transfer device includes a hook plate mechanism that advances and retreats synchronously with the loading mold. At the cake-making position, the hook plate mechanism pushes the cake-carrying and receiving plate into the lifting mechanism. At the loading position, the hook plate mechanism pulls the empty cake-receiving plate that has been stepped into place in the lifting mechanism into the cake-making position.

[0014] One structure of the lifting mechanism includes front and rear transmission chains which are symmetrically arranged on the left and right sides and run synchronously in opposite directions. Horizontal right-angle support bars are installed at equal intervals on the front and rear transmission chains on each side. The left and right opposite right-angle support bars form a supporting slide for inserting and pulling the corresponding cake plate.

[0015] Furthermore, each transmission chain is connected to the corresponding upper and lower transmission sprockets respectively. The upper transmission sprocket or the lower transmission sprocket on one side is a driving sprocket driven by a stepper motor. The driving sprocket is connected to the corresponding transmission sprocket on the other side through a reversing sprocket chain mechanism.

[0016] One structure of the loading mold includes a plurality of lower molds arranged in rows and columns on a mold frame, and a mold core provided in each lower mold is installed on a cylinder rod extending upward from a corresponding lower cylinder at the bottom of the mold frame; one structure of the forming mold includes an upper mold aligned with each lower mold, and the upper mold is installed on a cylinder rod extending downward from a corresponding upper cylinder, and each upper mold is provided with a blowing mechanism.

[0017] One structure of the hook plate mechanism includes a hook plate cylinder arranged on a mold frame, a cylinder rod extending upward from the hook plate cylinder is hinged to the rear end of a hook plate lever, and a front end of the hook plate lever is downwardly formed into a hook head.

[0018] Beneficial effects of the present invention:

[0019] 1. The pancake forming and arranging machine of the present invention combines pancake forming and arranging, saving manpower.

[0020] 2. The moon cakes made by the present invention are well formed, have clear patterns, no skirt corners, and are not easy to be nailed off.

[0021] 3. The moon cakes made by the present invention are evenly stressed and the baked moon cakes have a soft taste.

[0022] 4. The present invention can make 20 to 32 cakes per minute, with a fast discharge speed and significantly improved production efficiency.

[0023] 5. The present invention has reasonable structure and convenient operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The operation of the above-mentioned devices is controlled by an electrical program device, which conventionally includes a programmable PLC, a touch screen, a switching power supply, a leakage switch, a fuse holder, a relay and a button.

[0038] The workflow of the present invention is:

[0039] 1. At the loading position, put the pies neatly into each lower mold 15, start the pushing cylinder 2, and the extended cylinder rod drives the mold frame 14 to push the four lower molds 15 backward to the cake-making position. When the pushing cylinder 2 is started, the auxiliary tray photoeye 27 (corresponding to the cake-making position) set on the lifting frame 23 detects that there is no cake-receiving plate 5 on the supporting slide aligned with the cake-making position, and starts the stepper motor 12 to lift the lower cake-receiving plate 5 to the position aligned with the cake-making position. The left and right hook plate mechanisms 6 hook the cake-receiving plate 5 and wait for the cake-making to be completed before entering the cake-making position.

[0040] 2. Start the four upper cylinders 18, and at the same time press the four upper molds 17 down to fit tightly with the lower mold 15 to start the cake pressing and forming process (this process can ensure that the fillings are intact and not deformed), start the four lower cylinders 16 and at the same time lift the mold cores in the four lower molds 15, and after the cake is formed by inching air blowing, the four upper cylinders 18 lift the upper mold 17 at the same time, and the cylinder rods of the four lower cylinders 16 retract at the same time to return the mold cores in each lower mold 15 to their original positions, and the cylinder rod of the push cylinder 2 retracts. The mold frame 14 together with the four lower molds 15 are moved forward out of the cake-making position and returned to the loading position. At the same time, the left and right hook plate mechanisms 6 drag the cake receiving plate 5 to the cake-making position to receive the cakes. The cylinder rods of the left and right tray cylinders 28 are in a retracted and stable state without affecting the placement of the cake receiving plate 5. The four upper cylinders 18 slowly lower the upper mold 17 at the same time. The blowing mechanism in each upper mold 17 is started to blow the formed moon cakes onto the cake receiving plate 5. Subsequently, the four upper cylinders 18 lift the upper mold 17 at the same time.

[0041] 3. The pushing cylinder 2 drives the mold frame 14 to push the four lower molds 15 (filled with mooncakes) to the cake-making position. At the same time, the cylinder rods of the left and right tray cylinders 28 are synchronously lifted slightly, and the left and right hook plate mechanisms 6 steadily push the cake receiving plate 5 loaded with mooncakes to the corresponding supporting slide.

[0042] 4. The stepper motor 12 is started, and the cake receiving plate 5 loaded with moon cakes is stepped upward by one station. At the same time, the empty cake receiving plate 5 of the next station is moved up to align with the cake making position. The left and right hook plate mechanisms 6 hook the empty cake receiving plate 5 and wait for the cake making to be completed before entering the cake making position to receive the cake.

[0043] 5. The workflow of making pancakes → raising the plate → passing the plate → receiving the pancakes → passing the plate → raising the plate → making pancakes → arranging the plates is completed through this cycle.

[0044] In the described work flow, when the cake receiving plate 5 rises to the top position, the top tray photoeye 26 correspondingly arranged on the lifting frame 23 detects that the cake receiving plate 5 is in place, and the cake making is stopped until the staff takes out the top cake receiving plate 5, and then the cake making can be restarted. When there is no cake receiving plate 5 on the supporting slide corresponding to the cake making position, the cake making and placing are stopped, and the cake making program can be restarted until the secondary tray photoeye 27 detects that there is a plate (the cake receiving plate 5 is placed manually).

[0045] The present invention simulates manual operation, directly sends the mooncake blanks with the mooncake wrapped in it to the air pressure mold for one-time forming, has adjustable cake sending pressure, adjustable forming force and adjustable blowing force, and can achieve controllable cake making links.

[0046] The invention can ensure that the mooncake patterns are clearly formed without skirt corners and nails, and can also maintain the softness of the mooncake fillings and the good taste of the mooncakes. The production efficiency is greatly improved. 20kg to 32kg (20 to 32 mooncakes) can be completed per minute for 2-jin cakes, and 25kg to 40kg (10 to 16 mooncakes) can be completed per minute for 5-jin cakes.
