Description

Technical Field

[0001] The invention belongs to the technical field of baking paper laying, in particular to an automatic baking paper laying device for baking pancake production. Background Art

[0002] When producing scones, the traditional method is to pour the batter prepared with ingredients directly onto the conveyor belt, which then carries the batter into the oven for baking. The final processing and packaging are then carried out in the cold processing workshop. However, this method has obvious disadvantages. First, the surface of the steel belt must be kept clean to prevent it from contaminating the bottom of the batter. However, it is difficult to ensure that the steel belt is absolutely clean, and scones produced by conveying contaminated steel belts are likely to fail to meet the hygiene standards in batches. Excessive cleaning may wear out the steel belt. In addition, the steel belt and the scones may become adhered and difficult to separate, and the steel belt that has conveyed the scones will face the problem of being difficult to clean, thus forming a vicious cycle that affects production efficiency and yield rate.

[0003] Therefore, in order to overcome the above defects, our company chooses to add baking paper between the steel belt and the batter for isolation, which can ensure sanitary production, reduce the difficulty of cleaning the steel belt, and increase its service life.

[0020] Through the buckle groove and the buckle 2. As the batter conveyor line continues to convey, the magnet 3 climbs onto the block, and the buckle 2 then lifts the auxiliary spreader, thereby causing the auxiliary spreader and the steel belt to break away from the suction relationship. When the paper collector continues to drive the support arm to rotate, the support arm slides on the batter conveyor line and actively reduces its length to pass through the lower part between the paper collector and the batter conveyor line. After the support arm completes the fixation of the position between the auxiliary spreader, the auxiliary spreader as a whole can be used as a cross bar between the two corresponding support arms, which is used to cooperate with other cross bars to wind the baking paper and complete the collection of the baking paper.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 11 As shown, the present invention provides an automatic baking paper laying device for producing pancakes, comprising a batter conveyor line 100 and an oven 200 arranged on the conveying route of the batter conveyor line 100 for baking the batter thereon, and also comprising a baking paper spreader 300 and a paper collector 500 respectively arranged at both ends of the batter conveyor line 100 for laying and recycling baking paper, the baking paper spreader 300 comprising a cantilever 301 driven to rotate by a servo motor, the end of the cantilever 301 is movably connected with an auxiliary spreader 400 for clamping one end of the baking paper; the auxiliary spreader 400 rotates with the cantilever 301 and is lowered to be attracted to the surface of the steel belt of the batter conveyor line 100 and clamp the baking paper, and lays the baking paper on the steel belt as the batter conveyor line 100 is conveyed.

[0035] In the initial state, the cantilever 301 is tilted upward, and the servo motor controls the cantilever 301 to be pressed downward, and the auxiliary spreader 400 is pressed onto the steel belt. The auxiliary spreader 400 is fixed to the steel belt, and the baking paper is clamped and pulled and laid on the steel belt along with the conveying of the batter conveyor line 100. In addition, the extension direction of the steel belt of the auxiliary spreader 400 is vertical, which can ensure that the laying of the baking paper is always parallel to the steel belt. When the auxiliary spreader 400 reaches the end of the steel belt conveying, it cooperates with the paper collector 500 to roll up the baking paper.

[0036] like Fig.10 As shown, the auxiliary spreader 400 includes an upper plate 401 and a lower plate 402 glued to each other, and a hollow groove 4021 is opened on the lower plate 402. The hollow groove 4021 cooperates with the upper plate 401 to form a cavity interlayer. The auxiliary spreader 400 also includes an air guide plate 403 installed on the sides of the upper plate 401 and the lower plate 402 and connected to the cavity interlayer, and a negative pressure device 405 installed on the air guide plate 403 and connected to the inner cavity.

[0037] A cavity connected to the negative pressure device 405 is formed between the upper plate 401 and the lower plate 402. The cavity forms a negative pressure through the negative pressure device 405, and finally the negative pressure allows the bottom of the auxiliary spreader 400 to be sucked onto the steel belt, thereby completing the fixation between the auxiliary spreader 400 and the steel belt.

[0038] like Fig.10 As shown, the auxiliary spreader 400 further includes a rubber plate 404 disposed at the bottom of the lower plate 402, and a suction cup 4041 is provided on the rubber plate 404 to communicate with the cavity interlayer;

[0039] A clamping plate 406 is disposed at both ends of the upper plate 401 . The clamping plate 406 is provided with two buckle grooves 4061 at the same level, facing the baking paper spreading machine 300 and the paper collecting device 500 respectively.

[0040] The rubber sheet 404 is made of a high temperature resistant rubber and can be deformed to fit perfectly on the steel belt. The buckle groove 4061 is used to connect the auxiliary spreader 400 and the baking paper spreader 300.

[0041] like Fig.10 As shown, a pressure plate 408 is hingedly provided on the upper plate 401, and the pressure plate 408 cooperates with the lower plate 402 to clamp the baking paper. An arc-shaped recess is provided on the lower plate 402, and a rubber strip 4081 that can be embedded in the arc-shaped recess is provided at the bottom of the pressure plate 408. The rubber strip 4081 and the arc-shaped recess are used to clamp the baking paper.

[0042] The upper plate 401 and the lower plate 402 are tightly combined to form a cavity sandwich based on the empty groove 4021. Multiple empty grooves 4021 can be opened on the lower plate 402, and the cavity sandwich formed by multiple empty grooves 4021 can be connected through the air guide plate 403. Instead of opening a very long empty groove 4021 along the entire length of the lower plate 402, a larger cavity is prevented from affecting the negative pressure. The pressing plate 408 rotates to hold the baking paper, and the rubber strip 4081 and the arc-shaped groove on the lower plate 402 cooperate to increase the friction on the baking paper and improve the firmness of the baking paper.

[0043] The pressing plate 408 can be buckled onto the lower plate 402 or provided with an elastic hinge to clamp the baking paper. A person skilled in the art can design a suitable fixing method according to actual conditions, and is not limited to the limitation herein of the present application.

[0044] like Figures 9 to 11 As shown, the negative pressure device 405 includes a spring 4051 disposed in its inner cavity and a piston rod 4052 sleeved in the inner cavity with an interference fit, the spring 4051 elastically supports the spring 4051, and the inner cavity of the negative pressure device 405 is connected to the cavity interlayer;

[0045] The auxiliary spreader 400 is provided with a hook-shaped card 407 for engaging with the outer end of the piston rod. The top of the hook-shaped card 407 is hook-shaped and engages with the step at the outer end of the piston rod 4052. The bottom end of the hook-shaped card 407 is lower than the bottom end of the lower plate 402.

[0046] The spring 4051 in the negative pressure device 405 is in a compressed state in the initial state. The hook-shaped card 407 is located at the outer end of the piston rod 4052 to limit the above state. When the auxiliary spreader 400 is pressed on the steel belt, the hook-shaped card 407 is contacted with the steel belt and then the hook-shaped card 407 is lifted upward as a whole, so that the hook-shaped card 407 is separated from the piston rod 4052, and the limiting state of the piston rod 4052 is released, so the spring 4051 elastically supports the piston rod 4052 to move outward, and the piston rod 4052 sucks the air pressure in the cavity to form a negative pressure state and can simultaneously affect the pressure in the cavity interlayer, so that the suction cup 4041 of the rubber plate 404 is sucked on the steel belt to complete the fixation between the auxiliary spreader 400 and the steel belt.

[0047] like Figure 5 As shown, a pressure roller 302 and a buckle 303 are respectively provided on the inner and outer sides of the end of the baking paper spreading machine 300. The end face configuration of the buckle 303 is adapted to the cross-sectional configuration of the buckle groove 4061, and the buckle 303 can be snap-fitted with the buckle groove 4061.

[0048] The main function of the pressure roller 302 is to roll on the conveyor steel belt. The baking paper is clamped between the pressure roller 302 and the steel belt. The length of the pressure roller 302 covers the width of the baking paper and presses the baking paper on the steel belt to lay it evenly. The air bulge between the baking paper and the steel belt can be emptied to ensure the tightness of the two. The buckle 1 303 and the buckle groove 4061 are mutually engaged and connected. The cantilever 301 can be rotated by the servo motor set on the baking paper spreading machine 300. Therefore, when the cantilever 301 is rotated and lifted, the auxiliary spreader 400 can be lifted upward. In the initial state, the cantilever 301 is in the lifted state, which is convenient for adjusting the relative position between the baking paper, the steel belt and the cantilever 301 at the beginning. At the same time, for the convenience of cooperation, the auxiliary spreader 400 is also installed on the cantilever 301 through the buckle 1 303 at the beginning. Buckle 1 303 also completes the positioning of the auxiliary spreader 400, ensuring that after the auxiliary spreader 400 is engaged with buckle 1 303, the auxiliary spreader 400 is perpendicular to the extension direction of the steel belt, so that the baking paper pulled out can be parallel to the steel belt without deviation. When the cantilever 301 is rotated and lowered with the servo motor control, the auxiliary spreader 400 is horizontally attached to the steel belt, and the outer periphery of the pressure roller 302 is also attached to the steel belt. The docking direction of buckle 1 303 and the card plate 406 is also parallel to the conveying direction of the steel belt, so the card plate 406 can smoothly detach from buckle 1 303 when the steel belt is conveyed horizontally.

[0049] like Figure 1 and Figure 2 As shown, the paper collector 500 includes a support arm 501, a pad block 502 is fixedly installed at the end of the support arm 501, a magnet three 503 and a buckle two 504 are fixedly installed on the inner side of the pad block 502, the end face of the buckle two 504 is adapted to the cross-sectional configuration of the buckle groove 4061 and the initial position is located on the movement trajectory of the buckle groove 4061 conveyed by the steel belt of the batter conveyor line 100.

[0050] The auxiliary spreader 400 is transported to the cold processing workshop along the steel belt of the batter conveyor line 100, and finally arrives in front of the paper collector 500 located in the cold processing workshop, and is horizontally transported through the buckle groove 4061 to align with the buckle 2 504 to dock with it, and the magnet 3 503 is attracted to the card board 406 on the side of the card board 406, and the position of the auxiliary spreader 400 on the support arm 501 is fixed by the cooperation of the magnet 3 503 and the buckle 2 504 with the card board 406. The length of the support arm 501 is movable and retractable. When the paper collector 500 drives the support arm 501 to rotate, the support arm 501 slides on the batter conveyor line 100 and actively reduces its length to pass through the lower part between the paper collector 500 and the batter conveyor line 100. After the support arm 501 is fixed in position with the auxiliary spreader 400, the auxiliary spreader 400 as a whole can be used as a cross bar between two correspondingly arranged support arms 501, and is used to cooperate with other cross bars to wind up the baking paper and complete the collection of the baking paper.

[0051] like Figure 4 and Figure 6 As shown, a magnet 1 5011 is provided at the end of the inner sleeve rod of the support arm 501, and a magnet 2 5012 is provided near the end of the inner cavity of the sleeve of the support arm 501. The magnet 1 5011 and the magnet 2 5012 can attract each other when the support arm 501 is contracted to shorten and fix the length of the support arm 501.

[0052] The paper collector 500 is provided with multiple support arms 501, but in this solution, only one support arm 501 has a sleeve end provided with a cushion block 502, a magnet three 503, and a buckle two 504, etc., and the sleeve rod and the inner wall of the sleeve are respectively provided with a magnet one 5011 and a magnet two 5012. After the support arm 501 completes the capture of the auxiliary spreader 400, it rotates with the paper collector 500. When it rotates to the upper side of the circular track, the support arm 501 begins to tilt upward, so the outer sleeve slides down along the inner sleeve rod so that the magnet one 5011 and the magnet two 5012 attract each other. As a result, the support arm 501 is greatly shortened and the length is fixed. Therefore, when the support arm 501 rotates to the bottom of the circular track, it will not conflict with the steel belt, but shorten to a length almost the same as other support arms 501 to roll up the baking paper.

[0053] like Figure 1 and Figure 2 As shown, the batter conveyor line 100 includes a stopper 101 fixed on a bracket, the slope surface of the stopper 101 abuts against the magnet three 503 , and the batter conveyor line 100 also includes a position sensor 102 installed on the bracket for detecting the position of the auxiliary spreader 400 .

[0054] The stopper 101 disposed above it is mainly used to initially limit the support arm 501, and when the auxiliary spreader 400 moves toward the paper collector 500 and reaches the second buckle 504, in order to prevent the second buckle 504 and the buckle groove 4061 from not being properly engaged due to the contact friction between the third magnet 503 and the card plate 406, the stopper 101 plays a certain blocking role here, so that the horizontal movement of the third magnet 503 is blocked, so that the buckle groove 4061 and the second buckle 504 are engaged. As the batter conveying line 100 continues to convey, the third magnet 503 climbs onto the stopper 101, and the second buckle 504 lifts the auxiliary spreader 400, thereby causing the auxiliary spreader 400 and the steel belt to break away from the suction relationship. The main function of the position sensor 102 is to detect whether the auxiliary spreader 400 has arrived at a fixed position. In this solution, it is placed at the position of the buckle 2 504. When the auxiliary spreader 400 moves to the buckle 2 504 and completes the engagement with it, the position sensor 102 detects the auxiliary spreader 400 and reports its position to the control. The motor on the paper collector 500 drives the paper collector 500 to rotate, thereby starting the rolling of the baking paper.

[0055] like Figure 4 As shown, the delivery device 500 is disposed in a cold processing workshop 600 .

[0056] The baking paper is laid on the steel belt and transported along the batter conveyor line 100. After being baked in the oven, the batter is cooked and finally transported to the cold processing workshop along the batter conveyor line 100 for further processing or packaging. The paper collector 500 is located there and needs to collect the baking paper after the dough on it is unloaded. The auxiliary spreader 400 is transported to the paper collector 500 and cooperates with it to carry the baking paper for unified reeling.

[0057] The working principle and use process of the present invention:

[0058] The servo motor controls the rotation of the baking paper spreader 300 to press the cantilever 301 downward, driving the auxiliary spreader 400 to press onto the steel belt, the auxiliary spreader 400 fits with the steel belt, the hook-shaped card 407 is removed from contact with the steel belt, and the limit of the piston rod 4052 is released, so that the spring elasticity in the negative pressure device 405 supports the piston rod 4052 to form a negative pressure, and the cavity interlayer is decompressed, so that the bottom of the auxiliary spreader 400 can be sucked onto the surface of the steel belt. And the baking paper is clamped and pulled and laid on the steel belt with the assistance of the batter conveyor line 100. And the extension direction of the steel belt of the auxiliary spreader 400 is vertical, which can ensure that the laying of the baking paper is always parallel to the steel belt. The auxiliary spreader 400 reaches the end of the steel belt conveyor and cooperates with the paper collector 500 to reel up the baking paper.

[0059] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
