Description

Technical Field

[0001] This utility model relates to the field of tortilla machines, specifically to a Mexican tortilla machine with easily replaceable mold rollers. Background Technology

[0002] Currently, tortilla machines are used to flatten dough made from corn flour and die-cut it into Mexican tortillas in shapes such as circles or ovals. For example... Figure 6As shown, the corn pancake machine includes a first spreading roller 91, a second spreading roller 92, and a die roller 93. The die roller 93 has a protruding blade on its cylindrical surface and is located to the lower left of the first spreading roller 91. The corn pancake machine also includes a conveyor belt 94, the left end of which is located to the lower right of the first spreading roller 91. In operation, the second spreading roller 92 is positioned close to the left side of the first spreading roller 91. When dough is placed between the second spreading roller 92 and the first spreading roller 91, the first spreading roller 91 rotates counterclockwise, and the second spreading roller 92 rotates clockwise. The second spreading roller 92 and the first spreading roller 91 together drive the dough downwards through the second spreading roller 91. The gap between the dough and the first spreading roller 91 allows the dough to be squeezed through and flattened into a sheet. The sheet moves downward to the die roller 93. As the die roller 93 rotates clockwise, it moves the lower end of the soft sheet to the right, so that the sheet moves between the die roller 93 and the lower left of the first spreading roller 91. As the blade on the die roller 93 rotates to a position close to the first spreading roller 91, the blade can cut the sheet. Thus, the sheet is cut into the shape of a corn tortilla as it passes between the die roller 93 and the first spreading roller 91. The right end of the cut corn tortilla then reaches the conveyor belt 94, which moves the corn tortilla to the right.When cleaning the corn cake machine, the first spreading roller 91 and the second spreading roller 92 need to be separated. The corn cake machine is equipped with a fixed base 1 and a swing base 11. The first spreading roller 91 is rotatably mounted on the fixed base 1 via a bearing, and the second spreading roller 92 is rotatably mounted between the two swing bases 11 via a bearing. The two swing bases 11 are relatively fixedly connected. The mold roller 93 is rotatably mounted on the swing arm, which is hinged to the fixed base 1 and connected to a tension spring. The swing base 11 is equipped with a buckle block 3, and the fixed base 1 is connected to a hook arm 2. The left end of the hook arm 2 is fastened to the buckle block 3, and the swing base 11 is hinged to an unlocking arm 4. When the unlocking arm 4 is swung forcefully by hand, the right end of the unlocking arm 4 swings upward to lift the left end of the hook arm 2 so that the hook arm 2 disengages from the buckle block 3. Then, the upper part of the swing base 11 is pulled to the left, and the swing base 11 swings counterclockwise. The second spreading roller 92 then separates from the first spreading roller 91, opening the internal structure of the corn cake machine. This facilitates thorough cleaning of the inside of the corn cake machine, which is beneficial to food hygiene. After cleaning, swing the swing seat 11 clockwise back to its original position. The latch block 3 contacts and pushes the hook arm 2, causing the left end of the hook arm 2 to swing upward. When the latch block 3 passes the hook part of the left end of the hook arm 2 to the right, the elastic restoring force of the upper latch spring 26 pulls the left end of the hook arm 2 downward, thus restoring the latch block 3 to the hook arm 2. When it is necessary to replace the mold roller 93 to change the size or shape of the cut tortillas, the internal structure of the tortilla machine can also be opened using the above method. That is, the tortilla machine can be opened, and then the swing arm can be swung counterclockwise by hand, causing the mold roller 93 to swing to the lower left and away from the first spreading roller 91 so that the mold roller 93 can be easily removed upward. At the same time, the tension spring is further elastically stretched and deformed. However, when disassembling the mold roller 93, the elastic restoring force of the tension spring will cause the swing arm to swing clockwise to reset. Therefore, the worker has to hold the mold roller 93 to the lower left with one hand and then operate the disassembly of the mold roller 93 with the other hand, which makes the disassembly of the mold roller 93 inconvenient and needs to be improved.

Detailed Implementation

[0019] The present invention will now be further described with reference to the accompanying drawings.

[0020] This utility model relates to a Mexican tortilla machine with easily replaceable die rollers, such as... Figure 1 and Figure 2 As shown, it includes a fixed base 1 and a mold roller 93. The fixed base 1 is hinged with a swing arm 931, as shown in the figure. Figure 4 As shown, the swing arm 931 has a swing arm pivot point 9314 at the middle in the vertical direction, as... Figure 3 As shown, a swing support shaft is installed on the inner side of the fixed base 1. The aforementioned swing support shaft passes through the pivot point 9314 of the swing arm, as... Figure 1 and Figure 3 As shown, the mold roller 93 is rotatably mounted on the upper part of the swing arm 931. The lower end of the swing arm 931 is connected to a tension spring 932. Specifically, the front and rear ends of the connecting rod 934 are respectively connected to the lower ends of the corresponding swing arms 931 by corresponding screws. That is to say, the connecting rod 934 fixes the front and rear swing arms 931 relatively. The fixed seat 1 includes a fixed plate 10. The right end of the fixed plate 10 is connected to the body of the fixed seat 1 by corresponding screws. The front and rear ends of the crossbar 101 are respectively fixed to the corresponding fixed plate 10 by corresponding screws. The right end of the tension spring 932 hooks onto the middle part of the connecting rod 934 in the front-rear direction, and the left end of the tension spring 932 hooks onto the crossbar 101. Thus, the elastic restoring force of the tension spring 932 can drive the swing arm 931 to swing clockwise. In the working state, as shown... Figure 1 As shown, the mold roller 93 is located near the lower left of the first spreading roller 91. The rear end of the first spreading roller 91 is equipped with a first gear, and the rear end of the mold roller 93 is equipped with a second gear. At this time, the first gear meshes with the second gear, so that the first gear swing arm 931 blocks the swing arm 931 from swinging further clockwise. Alternatively, a limiting structure can be set to block the swing arm 931 from swinging further clockwise. Combined with the elastic restoring force of the tension spring 932, the mold roller 93 is kept in the working position.

[0021] like Figure 2 and Figure 3As shown, the corn cake machine of this utility model also includes a latching piece 933 for keeping the mold roller 93 in the maintenance position. One end of the latching piece 933 is hinged to the upper end of the swing arm 931. For example, an internal hexagonal head screw passes through the latching piece 933 and the swing arm 931. The internal hexagonal head screw is correspondingly screwed with a first anti-loosening nut. For example, the first anti-loosening nut can be found in "An Anti-loosening Nut" with Chinese Utility Model Patent Publication No. CN218894860U. Thus, the latching piece 933 and the swing arm 931 are limited in the axial direction of the internal hexagonal head screw between the head of the internal hexagonal head screw and the aforementioned first anti-loosening nut. Figure 5 As shown, the other end of the hook piece 933 has a hook hole 9330, as... Figure 2 and Figure 3 As shown, the mounting base 1 is provided with a protruding bracket 1101, and the hanging hole 9330 can be used to attach the protruding bracket 1101.

[0022] When the corn cake machine needs cleaning or the die roller 93 needs to be replaced, such as Figure 2 As shown, the hook arm 2 is unfastened from the buckle block 3, and then the swing seat 11 is swung counterclockwise to open, the second spreading roller 92 is separated from the first spreading roller 91, and then the hook piece 933 is pulled by hand, causing the hook piece 933 to drive the swing arm 931 to swing counterclockwise, and the mold roller 93 moves to the lower left. At the same time, the tension spring 932 is further elastically stretched and deformed. Then the hook hole 9330 of the hook piece 933 is hooked onto the protruding hanger 1101, that is, the hook hole 9330 is fitted onto the protruding hanger 1101. At this time, the protruding hanger 1101 blocks the swing arm 931 from swinging clockwise. Combined with the elastic restoring force of the tension spring 932, as Figure 2 As shown, this positions the swing arm 931 and the mold roller 93 in the maintenance position, allowing the worker to simultaneously operate both hands to disassemble the mold roller 93. The mold roller 93 can then be moved to the upper left and removed using both hands. When replacing or installing the mold roller 93, the worker can also operate both hands simultaneously to install it. After installation, the hook plate 933 is moved backward to disengage from the protruding bracket 1101, releasing the hook plate 933. The swing arm 931 then swings back to its original position due to the elastic restoring force of the tension spring 932. Figure 1 The state shown above. As can be seen from the above, this utility model facilitates the replacement of the mold roller.

[0023] Furthermore, such as Figure 1 and Figure 2As shown, the corn cake machine of this utility model also includes a swing seat 11. The lower end of the swing seat 11 is hinged to the fixed seat 1 via a protruding hanger 1101. Specifically, the lower end of the swing seat 11 is hinged to the fixed plate 10 of the fixed seat 1 via the protruding hanger 1101. One end of the protruding hanger 1101 forms a disc head. The protruding hanger 1101 passes through the swing seat 11 and the fixed plate 10. The inner end (i.e., the rear end) of the protruding hanger 1101 protrudes out of the fixed plate 10, so the inner end of the protruding hanger 1101 can pass through the hanging hole 9330. Specifically, the hook piece 933 is hooked to the rear end of the protruding hanger 1101 located at the front position. With the above arrangement, the hinge axis between the swing seat 11 and the fixed seat 1 can be used as the protruding hanger 1101, avoiding the need for a separate structure for connecting the hook piece 933. Figure 3 As shown, the inner end of the protruding bracket 1101 can be screwed with a corresponding second anti-loosening nut, so that the swing seat 11 and the fixing plate 10 are positioned in the front-back direction between the disc head of the corresponding protruding bracket 1101 and the second anti-loosening nut. Specifically, the hanging hole 9330 can be fitted onto the aforementioned second anti-loosening nut.

[0024] Furthermore, such as Figure 3 As shown, the hook piece 933 is provided with a shank 9331, which can be a screw. The shank 9331 is vertically screwed to the hook piece 933, so the worker can pinch the shank 9331 and pull the hook piece 933, which is convenient for operation.

[0025] Furthermore, such as Figure 4 As shown, the swing arm 931 is provided with a rotating positioning seat 9310, which can be welded to the swing arm 931, such as... Figure 1 and Figure 4 As shown, the rotating positioning seat 9310 has an upwardly opening slot 9311. The bottom of the slot 9311 is arc-shaped to correspond to and fit the shaft ends 9301 at both ends of the mold roller 93 axially. Figure 1 and Figure 3 As shown, the two axial ends of the mold roller 93 are respectively located in corresponding slots 9311. That is to say, the shaft end 9301 at the front end of the mold roller 93 is located in the slot 9311 of the forward rotating positioning seat 9310, and the shaft end 9301 at the rear end of the mold roller 93 is located in the slot 9311 of the rear rotating positioning seat 9310, so that both the front and rear ends of the mold roller 93 are rotatably supported. By setting the slots 9311, such as Figure 2 As shown, when the corn cake machine is in the open state, lifting the mold roller 93 allows the shaft heads 9301 at both ends of the mold roller 93 to slide out into the corresponding slots 9311, which facilitates the quick installation and removal of the mold roller 93.

[0026] Furthermore, such as Figure 4As shown, the rotating positioning seat 9310 is screwed with a positioning pin 9312 for positioning the end of the mold roller 93 at the bottom of the slot 9311. One end of the positioning pin 9312 is attached to the end of the mold roller 93. Specifically, the axial end of the mold roller 93 is a shaft head 9301, and one end of the positioning pin 9312 is attached to the upper part of the shaft head 9301. The shaft head 9301 is pressed against the bottom of the slot 9311 by gravity, and the upward movement of the shaft head 9301 is blocked by the positioning pin 9312. When it is necessary to disassemble the mold roller 93, first rotate the positioning pin 9312 to make the end of the positioning pin 9312 leave the slot 9311, and then move the shaft head 9301 upward out of the slot 9311.

[0027] Furthermore, such as Figure 4 As shown, a bushing 9313 is provided in the slot 9311. The bushing 9313 contacts the end of the mold roller 93, that is, the shaft head 9301 contacts the bushing 9313. The bushing 9313 can be made of polytetrafluoroethylene or copper. For food safety, it is preferred to make the bushing 9313 of polytetrafluoroethylene. The bushing 9313 acts as a sliding bearing, which helps to reduce the rotational resistance of the mold roller 93.
