Description

Technical Field

[0001] This utility model relates to the field of baking pancake oven technology, and in particular to a self-circulating baking pancake oven. Background Technology

[0002] Existing flatbread baking machines can be categorized into charcoal-fired, gas-fired, and electric-fired baking machines based on their heating energy source. Charcoal-fired baking machines require dedicated personnel for supervision, are difficult to control in terms of temperature, and are prone to producing toxic gases such as carbon monoxide. Gas-fired baking machines offer easier temperature control compared to charcoal-fired machines, but are less safe. Electric baking machines are widely used due to their superior safety and ease of temperature control.

[0003] A self-circulating sesame seed cake machine is disclosed in Chinese utility model patent application number CN202022662954.2. In this patent, a mold is set up to hold the dough, and then a conveying structure is used to send the dough into the baking cavity for baking. However, in this solution, the mold needs to be opened manually, which increases the labor intensity. In addition, the dough enters from one end and the finished product comes out from the other end. If one worker is in charge, he needs to walk back and forth to put in the dough and collect the finished product. If two people are in charge, it will increase the labor cost. Therefore, this application proposes a self-circulating sesame seed cake oven to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing self-circulating sesame seed cake ovens requiring manual mold opening and back-and-forth movement when placing the dough and collecting the finished product, and thus proposes a self-circulating sesame seed cake oven.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The self-circulating sesame seed cake oven includes an oven body, in which a mold for holding the dough is provided and a conveying assembly for circulating the mold are provided. It also includes an opening structure for automatically opening the mold and a limiting structure to prevent the mold from opening.

[0006] Preferably, the oven cavity is equipped with a heating component for heating and baking the dough.

[0007] Preferably, the conveying assembly consists of two sprocket sets, and the mold is mounted on the chains of the two sprocket sets.

[0008] Preferably, the mold consists of an upper mold and a lower mold, which are hinged together, and the lower mold is connected to two chains via a connecting plate.

[0009] Preferably, the mold opening structure includes a mold opening guide rail fixedly disposed at the upper front end of the furnace body, a roller disposed on the upper mold, and a roller disposed at the end of the roller, wherein the roller is capable of moving along the trajectory of the mold opening guide rail.

[0010] Preferably, the limiting structure includes a limiting ring, which is fixedly disposed at the tail end of the furnace body, and the roller can move along the inner ring of the limiting ring.

[0011] Preferably, the limiting structure further includes a limiting guide rail, which is fixedly installed on the lower part of the inner wall of the furnace body, and the roller can move along the top surface of the limiting guide rail.

[0012] Preferably, a proximity switch is also provided on the outside of the furnace body, and the sensing part of the proximity switch is positioned opposite the roller of the upper mold that is opened by the mold opening guide rail.

[0013] Preferably, a receiving box is fixedly installed at the bottom front end of the furnace body, and the receiving box is in communication with the interior of the furnace body.

[0014] Compared with the prior art, the present invention provides a self-circulating sesame seed cake oven, which has the following beneficial effects.

[0015] 1. This utility model, by setting a mold opening structure, can achieve the effect of automatically opening the mold. When a new dough is put in, there is no need to manually open the mold, saving labor intensity and solving the problem that the self-circulating sesame seed oven in the prior art requires manual mold opening.

[0016] 2. This utility model, through the setting of the limiting structure, enables the mold to return to the dough placement end under the drive of the conveying component, ensuring that the mold will not open on its own due to gravity during the return trip, thereby realizing the placement of dough and production of finished products at the same end of the oven body, thus solving the problem in the prior art of self-circulating sesame seed ovens that require back-and-forth movement for placing dough and collecting finished products.

[0017] 3. In this utility model, when the mold returns to the position above the receiving box, the limiting structure no longer limits it, allowing the mold to open by gravity, and then the product to fall into the receiving box by gravity.

[0018] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0027] Please refer to Figures 1-6 The self-circulating sesame seed cake oven includes a furnace body 1. The furnace body 1 has a mold for holding the dough and a conveying component for circulating the mold inside the furnace cavity. It also has a mold opening structure for automatically opening the mold and a limiting structure to prevent the mold from opening.

[0028] In a specific embodiment of this utility model, the mold is mainly used to hold the dough that is about to be baked. The conveying component drives the mold containing the dough to rotate in the oven cavity, and the dough is baked into a finished product in the oven cavity. During this process, the mold opening component is used to automatically open the mold, so that the workers can put the dough into the empty, opened mold. The limiting structure plays a limiting role in the conveying process of the mold, preventing the mold from opening by gravity on its return trip. When the mold containing the dough returns to the position below the mold opening structure after one cycle, the limiting structure no longer limits it. The mold will open by gravity, allowing the baked dough inside to automatically detach from the mold. Then the mold continues to run to the mold opening structure position and continues the next cycle. This cycle completes the baking of the dough.

[0029] The oven cavity is equipped with a heating component for heating and baking the dough. In this solution, the heating component is a heating tube 10, which is used to heat the inside of the oven cavity to achieve the effect of baking the dough. The heating tube 10 can be a conventional electric heating tube.

[0030] Specifically, this design includes three rows of heating tubes 10, all fixedly installed on the inner wall of the oven body 1. The three rows of heating tubes 10 are located above the upper mold, between the upper and lower molds, and below the lower mold, respectively. This arrangement can improve the heating uniformity of the heating tubes 10 and achieve uniform baking of the dough.

[0031] The conveying assembly consists of two sprocket sets, and the mold is set on the chain 5 of the two sprocket sets.

[0032] Specifically, the sprocket assembly includes sprockets 6 and chains 5. One chain 5 corresponds to two sprockets 6. Rotating shafts 7 are rotatably installed at both the front and rear ends of the furnace body 1. The two sprockets 6 on the same sprocket assembly are fixedly installed on the two rotating shafts 7 respectively. The sprockets 6 on the two sprocket assemblies on the same rotating shaft 7 are located at the two ends of the rotating shaft 7 respectively (note that they are not the end faces).

[0033] One of the rotating shafts 7 is rotated by a drive device, and then the chain 5 drives the other rotating shaft 7 to rotate. The drive device can be driven by a servo motor and a reducer. The drive device is fixedly installed on the outer wall of the furnace body 1, and the output shaft of the reducer is fixedly connected to one of the rotating shafts 7.

[0034] The mold consists of an upper mold 9 and a lower mold 3, which are hinged together. The lower mold 3 is connected to two chains 5 through a connecting plate 16. That is, the two ends of the connecting plate 16 are fixedly connected to the inner side of the two chains 5 respectively. The bottom surface of the lower mold 3 is fixedly connected to the connecting plate 16. Both the lower mold 3 and the upper mold 9 are provided with dough trays for holding dough.

[0035] In use, the drive device drives the chain 5 to rotate, and the connecting plate 16 drives the mold on it to move, and the movement path is the same as that of the chain 5, that is, it moves with the chain 5 to rotate.

[0036] The mold opening structure includes a mold opening guide rail 4 fixedly installed at the upper front end of the furnace body 1, a roller 15 installed on the upper mold 9, and a roller 14 installed at the end of the roller 15. The roller 14 can move along the trajectory of the mold opening guide rail 4.

[0037] If the roller 15 is fixedly connected to the upper mold 9, then the roller 14 is rotatably connected to the roller 15, thus ensuring that the roller 14 can achieve the rolling effect. Alternatively, if the roller 15 is rotatably connected to the upper mold 9, then the roller 14 can be fixedly connected to the roller 15, thus ensuring that both the roller 15 and the roller 14 can rotate. In this solution, the second solution is preferred. This arrangement prevents the roller 15 from generating significant hard friction when passing through the limiting ring 13, allowing the roller 15 to roll within the limiting ring 13, reducing wear caused by hard friction, and thereby improving the service life of the roller 15 and the limiting ring 13.

[0038] The mold opening guide rail 4 is located at the upper front end of the furnace body 1, which is the position where the dough is placed into the mold. Specifically, it is located at the upper front end of the chain 5, and the top plane of the mold opening guide rail 4 is higher than the top surface of the chain 5. The vertical front end of the mold opening guide rail 4 is located in front of the front end of the chain 5, and the bottom slope of the mold opening guide rail 4 is located below the corresponding sprocket 6.

[0039] The limiting structure includes a limiting ring 13, which is fixedly installed at the tail end of the furnace body 1, and the roller 15 can move along the inner ring of the limiting ring 13.

[0040] Specifically, the limiting ring 13 is U-shaped, with one end fixedly connected to the top of the tail end of the furnace body 1 and the other end fixedly connected to the bottom surface of the limiting guide rail 11. It is mainly used to limit the position of the roller 15. When the mold moves to this position, the movement trajectory of the corresponding roller 15 will be limited by the limiting ring 13. In this way, the relative position between the roller 15 and its corresponding lower mold 3 will not change, ensuring the closed state of the mold.

[0041] The limiting structure also includes a limiting guide rail 11, which is fixedly installed on the lower part of the inner wall of the furnace body 1, and the roller 14 can move along the top surface of the limiting guide rail 11.

[0042] The limiting guide rail 11 is flat and is horizontally fixed in the lower part of the inner wall of the furnace body 1. When the mold moves from the limiting ring 13 to this point, the roller 14 corresponding to the mold will contact the top surface of the limiting guide rail 11. That is, the limiting guide rail 11 is used to support the corresponding roller 14, so as to prevent the upper mold 9 of the mold from opening on its own due to gravity.

[0043] A downward ramp 12 is provided at the front end of the limiting guide rail 11. When the mold passes through this point, its upper mold 9 will open automatically, allowing the finished cake inside to fall out of the mold by itself.

[0044] A proximity switch 2 is also provided on the outside of the furnace body 1. The sensing part of the proximity switch 2 is positioned opposite the roller 14 of the upper mold 9 which is opened by the mold opening guide rail 4. The proximity switch 2 can monitor whether the mold is open. If it is, the conveying action of the conveying component is cut off, and it is restarted after a period of time. During this period, it is convenient for the staff to put in the dough. If not, it operates normally. The proximity switch 2 adopts existing equipment, and the control between it and the drive device adopts existing conventional settings.

[0045] A receiving box 8 is fixedly installed at the bottom front end of the furnace body 1, and the receiving box 8 is connected to the interior of the furnace body 1. The receiving box 8 is mainly used to receive the finished cakes after baking. The receiving box 8 is located below the slope 12. In addition, the bottom of the receiving box 8 can be set to be inclined, and an opening is provided at the lower end of the inclination. Then, a receiving basket is set below the opening, so that the finished cakes fall into the receiving box 8 and slide directly into the receiving basket. When the basket is full, an empty receiving basket can be directly replaced to achieve continuous operation.

[0046] Workflow: Refer to the attached diagram in this solution (see attached diagram for details). Figure 1 , Figure 2 , Figure 3 and Figure 5 Taking the mold located at the mold opening guide rail 4 as an example, this state is the mold opening state. The roller 14 supporting the mold is used on the top plane of the mold opening guide rail 4, so that the upper mold 9 and the lower mold 3 are in the open state. At this time, the roller 14 is located at the sensing point of the proximity switch 2, and the conveying component is in a paused state. Then, the worker brushes oil on the mold and puts in the dough. After a certain period of time, the conveying component continues to convey, moving the mold to the rear of the mold opening guide rail 4. During this process, the roller 14 is on the mold opening guide rail 4. Under the action of the inclined surface at the top rear end, it slowly falls until it disengages from the mold guide rail 4. Under the action of gravity, the upper mold 9 of the mold closes with the corresponding lower mold 3, and then enters the oven cavity for baking. When the mold moves to the limiting ring 13 (that is, at the rear end of the chain 5, just before entering the flipping stage), the roller 15 of the mold is restricted in its movement trajectory by the limiting ring 13 to avoid the problem of premature mold opening caused by the relative position change between the roller 15 and the lower mold 3. Then, when the mold moves to the limiting ring 13, it slowly falls. When the mold reaches the end of guide rail 11, the roller 14 of the mold will be supported by the guide rail 11 to prevent the mold from opening on its own during the return stroke. When the mold moves to the front end of the guide rail 11 and disengages from the guide rail 11, the upper mold 9 of the mold will open automatically under the action of gravity, and the finished cake inside will automatically detach from the mold (achieving the function of automatic mold opening and delivery of finished products) and fall into the receiving box 8 (this allows the operation of placing the cake blank and collecting the finished product to be concentrated at the same end, reducing the number of workers walking back and forth. In addition, by reducing the number of standing positions at one end, the length of the equipment can also be reduced to a certain extent). Then the mold continues to move forward. During the upward movement, the position of its roller 14 will be restricted by the front end face of the mold opening guide rail 4. That is, during the upward movement, the roller 14 will stick to the front end face of the mold opening guide rail 4. After the mold moves completely above the chain 5, the roller 14 can be located on the top surface of the mold opening guide rail 4, achieving the effect of mold opening (achieving the effect of automatic mold opening). At this point, the mold completes one cycle, and other molds also cycle in the same way.

[0047] In addition, in some other embodiments, the receiving box 8 can be removed, and several layers of staggered conveyor belts can be set inside the support legs of the furnace body 1. The conveyor belts carry the finished products in a reciprocating motion, thereby achieving a natural cooling effect and avoiding poor heat dissipation caused by the accumulation of finished cakes. This prevents the heat from condensing into water after contacting the outside air, which could cause the finished cakes to collapse or bubble on the surface. Specifically, taking a two-layer conveyor belt as an example, both conveyor belts are horizontally set. The front part of the upper conveyor belt is located at the original position of the receiving box 8, and the rear end of the lower conveyor belt extends beyond the rear end of the upper conveyor belt. Then, a receiving basket is placed below the front end of the lower conveyor belt. During operation, the front of the upper conveyor belt catches the falling finished products and then transports them to the rear. Upon reaching the rear, they naturally fall onto the lower conveyor belt, which then transports the cakes forward. After reaching the front of the lower conveyor belt, the cakes naturally fall into the receiving basket. During the conveying process, the cakes naturally cool down, preventing condensation or swelling that may occur if they are directly piled up after being taken out of the oven. The number of conveyor belt layers can be selected according to actual needs. If you want the cakes to dry for a longer time, you can add more conveyor belts. The conveying speed of the conveyor belts can be the same as the conveying speed of the conveying components. In addition, to prevent the finished cakes from falling off the conveyor belt, a protective railing can be installed around the edge of the conveyor belt.
