Description

Technical Field

[0001] This utility model relates to the field of bread production, and in particular to an integrated kneading, proofing and shaping device for toast bread. Background Technology

[0002] In toast production, kneading, proofing, and shaping are the core steps that determine the product's taste and appearance. Currently, core processes such as kneading and proofing in toast production mostly rely on independent equipment, requiring manual transfer of the dough. This not only increases labor intensity but also makes the dough quality susceptible to changes in temperature and humidity during transfer. To solve these problems, developing an integrated toast production machine that streamlines the entire process has become an urgent need in the industry. Summary of the Invention

[0003] To address the shortcomings mentioned above in the background technology, this utility model provides an integrated kneading, proofing, and shaping device for toast bread.

[0004] The present invention adopts the following technical solution: An integrated kneading, proofing, and shaping device for toast bread, characterized in that the device comprises: A frame, the frame including columns and bases and top plates at both ends of the columns; A turntable, which is a ring structure, is mounted on the base and can rotate around the axis of the column; a barrel is provided on the turntable. A dough kneading mechanism, comprising a dough kneading body that can be raised and lowered along the column and a stirrer that rotates at its bottom.

[0005] The proofing mechanism includes a liftable proofing cover with an air inlet pipe running through it. Temperature sensors are installed on both sides of the air inlet pipe. A sealing ring is provided on the bottom surface of the proofing cover. The outer diameter of the sealing ring is larger than the outer diameter of the barrel and the inner diameter is smaller than the inner diameter of the barrel. An atomizing nozzle is provided at the end of the air inlet pipe. When the turntable rotates the bucket to the kneading station, the kneading body descends to knead the dough; when it rotates to the proofing station, the proofing cover descends to seal the opening of the bucket, and the air inlet pipe introduces water vapor for proofing.

[0006] As a further improvement, the outer ring surface of the column is provided with a sliding groove with a lead screw, and the kneading body is threadedly connected to the lead screw through a threaded sleeve.

[0007] As a further improvement, the proofing cover is driven by a cylinder mounted on the top plate.

[0008] As a further improvement, the air intake pipe is located at the center of the waking cap.

[0009] As a further improvement, the bottom surface of the proofing cap is provided with an annular groove for mounting the sealing ring.

[0010] As a further improvement, the annular groove is provided with multiple vent holes.

[0011] As a further improvement, the barrel body is detachably connected to the turntable.

[0012] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: Based on a vertical frame, it integrates a turntable, a kneading mechanism, and a proofing mechanism. The turntable achieves precise rotation through internal meshing transmission, driving the detachable bucket to switch work positions; the bucket is quickly fixed to the positioning block by an electromagnetic adsorption structure, making assembly and disassembly efficient and stable. The kneading mechanism is driven by a lead screw and a guide rod to ensure precise lifting and kneading of the mixer. The proofing mechanism drives the proofing cover through a cylinder, and with a sealing ring and vent holes, it achieves sealing and leak prevention and air pressure balance, while the atomizing nozzle and temperature sensor ensure stable proofing temperature and humidity. The device achieves automated process connection, improving production efficiency and product quality. Attached Figure Description

[0019] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0020] As attached Figure 1 As shown, an integrated kneading, proofing and shaping device for toast bread is disclosed. The device includes a frame 1, a turntable 2, a kneading mechanism 4 and a proofing mechanism 5.

[0021] As attached Figure 1 and Figure 3As shown, the frame 1 serves as the basic support structure of the device. The frame 1 mainly consists of a column 12 and a top plate 13 and a base 11, which are respectively fixed to the upper and lower ends of the column 12. The base 11 provides an installation platform for the turntable 2, while the top plate 13 is used to fix the proofing mechanism 5. The column 12 not only connects the base 11 and the top plate 13, but also provides guidance and drive support for the lifting and lowering of the kneading mechanism 4, forming a stable "vertical frame" structure.

[0022] As attached Figure 1 As shown, the turntable 2 adopts a ring design and is horizontally installed on the upper surface of the base 11. Its rotation axis is completely coincident with the central axis of the column 12, ensuring that the drum 3 can be accurately aligned with each workstation when the turntable 2 rotates. The rotation power of the turntable 2 is provided by a rotary motor located inside the base 11. The specific transmission method is as follows: a toothed ring coaxial with itself is fixed on the bottom surface of the turntable 2. The end of the motor shaft of the rotary motor is connected to a drive gear. The drive gear and the toothed ring form an internal meshing transmission. The precise positioning and rotation of the turntable 2 are achieved by the forward and reverse rotation of the motor, driving the drum 3 to switch between the kneading workstation and the proofing workstation.

[0023] As attached Figure 2 As shown, the bucket 3 serves as the dough container and is detachably connected to the turntable 2. This is achieved through a pre-installed mounting base 12 on the turntable 2. The mounting base 12 has a mounting groove 13 on its top that matches the bottom contour of the bucket 3. Simultaneously, the mounting base 12 and the bucket 3 are connected by an electromagnetic adsorption structure, facilitating quick assembly and disassembly of the bucket 3 (such as cleaning or replacing it) while ensuring stability during operation. To further improve the positioning accuracy of the bucket 3 after installation, the groove wall of the mounting groove 13 protrudes outward to form a positioning groove 14. Correspondingly, the outer ring surface of the bottom of the bucket 3 has a positioning block 31 that matches the positioning groove 14. During installation, the positioning block 31 is embedded in the positioning groove 14, effectively preventing the bucket 3 from shifting or rotating during kneading or turntable 2 rotation.

[0024] The electromagnetic adsorption structure mainly consists of two parts: an electromagnetic coil assembly and a magnetic adsorption plate. These are respectively installed on the mounting base 12 of the turntable 2 and the bottom of the barrel 3, forming a precise fit. The electromagnetic coil assembly is installed inside the mounting base 12 of the turntable 2, specifically embedded in the bottom of the mounting groove 13. This assembly includes a ring-shaped electromagnetic coil, a coil protective shell, a wire interface, and an insulation layer. The magnetic adsorption plate is fixed to the bottom of the barrel 3 and is coaxially aligned with the electromagnetic coil assembly. The adsorption plate is made of low-carbon steel plate with high magnetic permeability, its outer diameter matching the bottom size of the mounting groove 13, and it is welded to the bottom of the barrel 3. Furthermore, the upper surface of the adsorption plate (the side connected to the barrel 3) is treated with rust prevention (such as galvanizing), while the lower surface (the side opposite the electromagnetic coil assembly) is polished to reduce the contact gap with the bottom of the mounting groove 13 and improve magnetic adsorption efficiency. The electromagnetic adsorption structure operates based on the principle of "electromagnetic induction and magnetic adsorption," and its operation is linked to the device's control system for automated control.

[0025] As attached Figure 3 and Figure 4 As shown, the kneading mechanism 4 is used to complete the mixing and kneading of the dough, and mainly consists of the kneading body 41, the mixer 42, and the matching drive and guide components.

[0026] The kneading body 41 is located on the outside of the column 12 and can move up and down along the column 12. Its lifting power and guidance are achieved through a sliding groove 121 on the outer ring surface of the column 12, a lead screw 122, and a threaded sleeve 43 on the kneading body 41. The sliding groove 121 is opened along the height direction of the column 12, and a lead screw 122 is built into it. The bottom end of the lead screw 122 is connected to a lead screw motor located inside the column 12. A threaded sleeve 43 is fixed to the inner side of the kneading body 41, and the threaded sleeve 43 is embedded in the sliding groove 121 and forms a threaded engagement with the lead screw 122. When the lead screw motor starts, the lead screw 122 rotates, driving the threaded sleeve 43 to move up and down along the sliding groove 121 through threaded transmission, thereby realizing the lifting and lowering of the kneading body 41.

[0027] The mixer 42 is installed on the bottom surface of the kneading body 41. Its rotational power is provided by a kneading motor located inside the kneading body 41. The kneading motor is connected to the mixer 42 through a reduction gear mechanism, and the mixing speed can be adjusted according to the kneading requirements of the dough. At the same time, in order to prevent the kneading body 41 from rotating during the lifting and lowering process and to ensure that the mixer 42 is accurately aligned with the bucket 3, a guide rod is also provided parallel to the lead screw 122 in the slide groove 121. A guide rod hole is opened at the corresponding position of the kneading body 41, and the guide rod passes through the guide rod hole, so that the kneading body 41 slides along the guide rod, which plays a stable guiding role and ensures that the mixer 42 can accurately extend into the bucket 3 to perform the kneading operation.

[0028] As attached Figure 5 and Figure 6 As shown, the proofing mechanism 5 is used to provide a suitable temperature and humidity environment for the dough (by adjusting with water vapor) to achieve dough proofing. It mainly includes a proofing cover 51, an air inlet pipe 52, a temperature sensor 53, a sealing ring 54, and matching drive and connection components.

[0029] The proofing cover 51 is a circular cover structure, installed below the top plate 13. Its lifting and lowering action is driven by a cylinder 55 fixed on the top plate 13: the cylinder body of the cylinder 55 is fixed on the lower surface of the top plate 13, and the end of the piston rod of the cylinder 55 is connected to the upper surface of the proofing cover 51. Through the extension and retraction of the piston rod of the cylinder 55, the proofing cover 51 can be driven to quickly descend (lock into the barrel 3) or rise (detach from the barrel 3), thereby achieving the sealing and opening of the barrel 3.

[0030] To ensure stable temperature and humidity within the barrel 3 during proofing, the bottom surface of the proofing cover 51 is provided with an annular groove 57, into which a sealing ring 54 is embedded, and the sealing ring 54 is coaxially aligned with the proofing cover 51. The dimensions of the sealing ring 54 are precisely designed: its outer diameter is larger than the outer diameter of the barrel opening of the barrel 3, and its inner diameter is smaller than the inner diameter of the barrel opening of the barrel 3. When the proofing cover 51 is lowered and closed, the sealing ring 54 can completely cover the edge of the barrel opening, forming a reliable seal and preventing water vapor leakage. At the same time, multiple vent holes 58 are provided through the bottom of the annular groove 57. When the proofing cover 51 is pressed down, the sealing ring 54 deforms outward under axial pressure. If the annular groove 57 had no vent holes 58, the air in the enclosed space would be compressed, forming "pressure resistance," preventing the sealing ring 54 from completely fitting the side wall of the annular groove 57 and the surface of the barrel opening of the barrel 3, resulting in localized micro-gaps of ≤0.1mm, through which temperature and humidity can easily leak. At the same time, it can balance the air pressure inside and outside the barrel 3 during the proofing process, and avoid damage to the sealing structure due to excessive air pressure inside the barrel.

[0031] An air inlet pipe 52 runs through the central axis of the proofing cover 51. Its top end connects to the outlet of an external steam generator (such as a steam generator) via a flexible hose 56, and its bottom end extends below the proofing cover 51, with an atomizing nozzle installed at the end. The steam is atomized by the nozzle and sprayed more evenly onto the dough surface inside the container 3, preventing uneven temperature and humidity from affecting the proofing effect. To monitor the proofing temperature inside the container 3 in real time, temperature sensors 53 are symmetrically installed on both sides of the air inlet pipe 52. The sensing ends of the temperature sensors 53 face inwards towards the inside of the container 3, allowing them to collect real-time temperature data and feed it back to the control system. When the temperature deviates from the set range, the control system adjusts the output of the steam generator to ensure a stable proofing temperature.

[0032] During operation, the dough material to be kneaded is placed into the barrel 3. Through the cooperation of the positioning block 31 and the positioning groove 14, the barrel 3 is installed on the mounting base 12 of the turntable 2, and the electromagnetic adsorption structure is activated to fix the barrel 3.

[0033] The rotary motor is started, and through the meshing transmission of the drive gear and the gear ring, the turntable 2 is rotated, causing the bucket 3 to move to the kneading station (located directly below the kneading mechanism 4). Then, the lead screw motor starts, driving the lead screw 122 to rotate, which, through the threaded sleeve 43, causes the kneading body 41 to descend along the column 12 until the mixer 42 extends into the raw materials inside the bucket 3. Next, the kneading motor starts, driving the mixer 42 to rotate and knead the raw materials; during the kneading process, the guide rod ensures the stable raising and lowering of the kneading body 41, preventing the mixer from shifting.

[0034] After kneading is complete, the kneading motor stops, and the lead screw motor reverses to lift and reset the kneading body 41. The rotary motor restarts, driving the turntable 2 to rotate the bucket 3 to the proofing position (directly below the proofing mechanism 5). At this time, the piston rod of the cylinder 55 extends, pushing the proofing cover 51 down until the sealing ring 54 presses against the edge of the bucket 3, forming a sealed space. Subsequently, the steam generator starts, and steam is atomized through the hose 56, air inlet pipe 52, and atomizing nozzle before entering the bucket 3. The temperature sensor 53 monitors the temperature inside the bucket in real time and provides feedback for adjustment, ensuring that the dough proofs under suitable temperature and humidity. During the proofing process, the vent 58 balances the air pressure inside and outside the bucket, preventing damage to the sealing structure.

[0035] After proofing is complete, the piston rod of cylinder 55 retracts, causing the proofing cover 51 to rise and reset. The rotary motor can rotate the barrel 3 to the next station (such as the forming station) as needed, or stop rotating, close the electromagnetic adsorption structure, and remove the barrel 3 for subsequent processing (such as dough removal and barrel 3 cleaning).

[0036] In summary, this utility model device is based on a vertical frame 1, integrating a turntable 2, a kneading mechanism 4, and a proofing mechanism 5. The turntable 2 achieves precise rotation through internal meshing transmission, driving the detachable bucket 3 to switch work positions; the bucket 3 is quickly fixed to the positioning block 31 using an electromagnetic adsorption structure, making assembly and disassembly efficient and stable. The kneading mechanism 4 is driven by a lead screw 122 and a guide rod, ensuring precise lifting and kneading of the mixer 42. The proofing mechanism 5 drives the proofing cover 51 through a cylinder, and with a sealing ring 54 and a vent 58, achieves sealing and leak prevention and air pressure balance, while an atomizing nozzle and a temperature sensor 53 ensure stable proofing temperature and humidity. The device achieves automated process integration, improving production efficiency and product quality.

[0037] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
