[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0022] Please see Figure 1 The diagram shown is a structural schematic of an embodiment of the shortbread baking device of this utility model. Please refer to [link / reference]. Figure 1 This paper provides a detailed description of a shortbread baking apparatus.

[0023] A shortbread baking device includes a front drive roller 1, a baking oven 2, a heating tube 3, a baking mesh belt 4, a rear drive roller 5, and insulation cotton. The front drive roller 1 and the rear drive roller 5 are respectively arranged at the front end and the rear end of the baking oven 2, and both ends of the front drive roller 1 and the rear drive roller 5 are mounted on the side walls of the baking oven 2 through bearing seats.

[0024] The baking mesh belt 4 is wound around the outside of the front drive roller 1 and the rear drive roller 5 to form a ring transmission structure; stable support is achieved through the bearing seat, and the baking mesh belt 4 is wound around the outside of both to form a ring transmission, ensuring that the biscuit dough can be transported smoothly.

[0025] The heating tubes 3 are installed inside the baking oven 2, and are divided into two rows, upper and lower. The upper row of heating tubes 3 is installed at the top inside the baking oven 2, and the lower row of heating tubes 3 is installed at the bottom inside the baking oven 2. Both rows of heating tubes 3 are parallel to the transmission direction of the baking mesh belt 4, and the spacing between the upper and lower rows of heating tubes 3 is equal. The heating tubes 3 are divided into two rows inside the oven, which can heat the biscuit dough from both the top and bottom, ensuring uniform heating.

[0026] The insulation cotton is laid on the inner wall of the baking oven 2, covering the entire inner space of the baking oven 2; the insulation cotton laid on the inner wall of the oven can effectively reduce heat loss and improve energy utilization.

[0027] It also includes a servo motor, which is fixedly installed on the rear exterior of the baking oven chamber 2. The output shaft of the servo motor is connected to one end of the rear drive roller 5 via a coupling. The servo motor is connected to the rear drive roller 5 via the coupling to provide stable power for the rotation of the baking mesh belt 4. Its technical effect is to make the structure of the baking device more stable and reliable, realize the smooth conveying and uniform heating of the biscuit dough, and at the same time have a good heat preservation and energy saving effect, ensuring baking quality and production efficiency. The servo motor can be the HF-SN series servo motor manufactured and sold by Mitsubishi Electric Automation China Co., Ltd.

[0028] Furthermore, an adjusting screw and an adjusting nut are provided between the bearing seat of the front drive roller 1 and the side wall of the baking oven 2. One end of the adjusting screw is fixedly connected to the bearing seat, and the other end passes through the side wall of the baking oven 2 and is threaded into the adjusting nut. By rotating the adjusting screw, the bearing seat can be moved along the side wall of the baking oven 2. The bearing seat of the front drive roller 1 is connected to the side wall of the oven through the adjusting screw and the adjusting nut. When the adjusting screw is rotated, the bearing seat can move along the side wall, which facilitates and quickly adjusts the tension and skew of the baking mesh belt 4, avoids the mesh belt from slipping or running off-center, ensures stable transmission of the biscuit dough during baking, and improves the practicality and reliability of the baking device.

[0029] Furthermore, the number of upper heating tubes 3 is two, and the two upper heating tubes 3 are spaced apart along the width direction of the baking mesh belt 4. The number of lower heating tubes 3 is two, and the two lower heating tubes 3 are spaced apart along the width direction of the baking mesh belt 4. The upper heating tubes 3 and the lower heating tubes 3 correspond one-to-one in the vertical direction. Both the upper and lower heating tubes 3 are provided in pairs and are spaced apart along the width direction of the mesh belt and vertically correspond to each other. This makes the distribution of heating tubes 3 in the baking oven 2 more reasonable, and can evenly heat the biscuit dough from multiple directions, ensuring that the biscuit dough is heated evenly during the baking process. This results in biscuits with uniform color and crisp and delicious taste.

[0030] Furthermore, the servo motor is fixed to the rear exterior of the baking oven 2 via a mounting bracket. The mounting bracket includes a horizontal fixing plate and a vertical support plate. The horizontal fixing plate is fixed to the rear outer wall of the baking oven 2, and the vertical support plate is vertically fixed below the horizontal fixing plate. The servo motor is fixedly installed on the outer side wall of the vertical support plate, ensuring that the servo motor is securely and reliably installed. This allows the servo motor to stably provide power to the rear drive roller 5, thereby ensuring the smooth rotation of the baking mesh belt 4 and avoiding the impact on the baking quality of the cookies due to unstable motor installation.

[0031] Furthermore, the insulation cotton is high-temperature resistant insulation cotton with a thickness of 3-5 cm. The insulation cotton is adhered to the inner wall of the baking oven 2 with a high-temperature resistant adhesive to form a complete insulation layer, which can effectively prevent heat from being lost from the baking oven 2 to the outside, maintain the temperature inside the oven, reduce energy consumption, and make the temperature distribution inside the oven more uniform, which is conducive to improving the baking quality of biscuits.

[0032] Furthermore, the baking mesh belt 4 is a metal wire mesh belt with a mesh aperture of 2-5 mm. Tensioning protrusions are provided on both sides of the baking mesh belt 4. Annular grooves that cooperate with the tensioning protrusions are provided on the outer walls of both the front drive roller 1 and the rear drive roller 5. The metal wire mesh belt has good air permeability and thermal conductivity, which allows the biscuit dough to be heated more evenly during baking. The appropriate mesh size prevents the biscuit dough from falling off. The cooperation between the tensioning protrusions and the annular grooves further improves the stability of the mesh belt transmission, ensuring that the biscuit dough can pass smoothly through the baking oven 2 to complete the baking process.

[0033] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
