[0004] To overcome the problems existing in related technologies, this utility model provides a roller pressing structure that can well meet the thickness uniformity of bread, ensure the bread can be demolded without damage, eliminate the need for manual operation, and ensure the quality of the product.

[0005] This utility model provides a roller pressing structure for a baking tray conveying device, including a pressure roller, a fixed plate and an adjusting plate located at both ends of the pressure roller, a mounting plate, a screw, a transmission rod, and a drive assembly for driving the pressure roller to rotate.

[0006] The fixed plate is provided with a sliding groove extending in the vertical direction. The two ends of the pressure roller are accommodated in the sliding groove and rotatably connected to the adjusting plate. The mounting plate is fixed on the fixed plate. The mounting plate is provided with a shaft hole for the screw to pass through. The first end of the screw is provided with a turntable, and the second end is threadedly connected to the adjusting plate. The transmission rod is rotatably connected to the two fixed plates and is connected to the screw through gear meshing.

[0007] In some embodiments, the number of pressure rollers is two, the drive assembly includes a motor, a transmission belt and a tension adjustment mechanism, the motor shaft of the motor is provided with a drive gear, and both the pressure rollers and the tension adjustment mechanism are provided with driven gears. The drive gear and the driven gear are connected by a transmission belt, and the tension adjustment mechanism is used to adjust the tension of the transmission belt.

[0008] In some embodiments, the tension adjustment mechanism includes a spring, a slider, and a fixed shaft. The fixed plate has a horizontal bar hole, the spring is horizontally disposed on the fixed plate, the spring is connected to the slider, the slider is embedded in the horizontal bar hole, the fixed shaft is connected to the slider, and the driven gear is sleeved on the fixed shaft.

[0009] In some embodiments, a housing is also included, in which the pressure roller, fixing plate, transmission rod, and adjusting plate are all disposed. The housing is provided with mounting holes, and the motor is disposed on the housing. The housing is connected and fixed to the baking tray conveying device by a latch.

[0010] In some embodiments, the latch includes a claw, a fixed base, a handle, and a retaining ring.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] The technical solutions of the embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0029] like Figures 1 to 3 As shown, the present invention provides a roller pressing structure for a baking tray conveying device, including a pressure roller 1, a fixed plate 2 and an adjusting plate 3 located at both ends of the pressure roller 1, a mounting plate 4, a screw 5, a transmission rod 6, and a driving assembly 7 for driving the pressure roller 1 to rotate.

[0030] The fixed plate 2 is provided with a sliding groove 20 extending in the vertical direction. The two ends of the pressure roller 1 are accommodated in the sliding groove 20 and rotatably connected to the adjusting plate 3. The mounting plate 4 is fixed on the fixed plate 2. The mounting plate 4 is provided with a shaft hole for the screw 5 to pass through. The first end of the screw 5 is provided with a turntable 8, and the second end is threadedly connected to the adjusting plate 3. The transmission rod 6 is rotatably connected to the two fixed plates 2 and is meshed with the screw 5 through a gear.

[0031] In the bread processing and production process, after proofing, the dough is baked in a multi-layer tunnel oven and then conveyed to a demolding machine via a baking tray conveyor for demolding. The roller pressing structure provided by this invention has fixed plates 2 placed on both sides at the end of the bread conveying path in the baking tray conveyor. The pressure roller 1 is located above the conveyor belt of the baking tray conveyor, and the bread in the baking tray enters below the pressure roller 1 under the drive of the conveyor belt. The bread is shaped by the action of the pressure roller 1, ensuring that the height of the bread does not exceed the demolding height. The fixed plate 2 is provided with a sliding groove 20 for the free movement of the pressure roller 1. The operator adjusts the thread depth of the screw 5 and the adjusting plate 3 by rotating the turntable 8, thereby adjusting the distance between the pressure roller 1 and the conveyor belt. Simultaneously, the screw 5 meshes with the transmission rod 6, driving the transmission rod 6 to rotate, so that the screw 5 at the other end can rotate synchronously, achieving synchronous lifting and lowering of the adjusting plates 3 at both ends of the pressure roller 1, ensuring that the pressure roller 1 maintains a stable horizontal posture. To reduce the friction between the pressure roller and the bread and prevent the pressure roller from damaging the appearance of the bread, the rotation of the pressure roller 1 is achieved by a drive assembly 7. In some embodiments, the speed at which the pressure roller 1 rotates is the same as the conveying speed of the conveyor belt. That is, when the linear speed of the pressure roller 1 is equal to the conveying speed of the conveyor belt, the friction between the roller surface of the pressure roller 1 and the bread is minimized, which can avoid the problem of bread breakage caused by friction.

[0032] Furthermore, the number of pressure rollers 1 is two. The drive assembly 7 includes a motor, a transmission belt 71 and a tension adjustment mechanism. The motor shaft of the motor is provided with a drive gear 72. Both the pressure rollers 1 and the tension adjustment mechanism are provided with driven gears 73. The drive gear 72 and the driven gear 73 are connected by transmission belt 71. The tension adjustment mechanism is used to adjust the tension of the transmission belt 71.

[0033] Furthermore, the aforementioned tension adjustment mechanism includes a spring 74, a slider 75, and a fixed shaft 76. The fixed plate 2 is provided with a horizontal bar hole 21. The spring 74 is horizontally arranged on the fixed plate 2. The spring 74 is connected to the slider 75. The slider 75 is embedded in the horizontal bar hole 21. The fixed shaft 76 is connected to the slider 75. The driven gear 73 is sleeved on the fixed shaft 76.

[0034] Furthermore, the above-mentioned roller pressing structure also includes a housing 9, in which the pressure roller 1, the fixing plate 2, the transmission rod 6, and the adjusting plate 3 are all disposed within the housing 9. The housing 9 is provided with mounting holes, and the motor is disposed on the housing 9. The housing 9 is connected and fixed to the baking tray conveying device through a locking buckle 10.

[0035] In this embodiment, a stepper motor can be used, which is a type of electric motor that converts electrical pulse signals into corresponding angular or linear displacements. For each input pulse signal, the rotor rotates by an angle or moves forward one step. The output angular or linear displacement is proportional to the number of input pulses, and the rotational speed is proportional to the pulse frequency. Therefore, the stepper motor can precisely control the rotation amplitude of the pressure roller 1, ensuring that the rotational speed of the pressure roller 1 is synchronized with the conveyor belt speed of the baking tray conveyor. When there are two pressure rollers 1 in the roller pressing structure, the two pressure rollers 1 are located on the same horizontal plane. At this time, the motor and the pressure roller 1 are connected by a transmission belt 71. When the pressure roller 1 moves up and down under the action of the screw 5, the tension of the transmission belt 71 can be adjusted by the tension adjustment mechanism to ensure the meshing strength between the driving gear 72 and each driven gear 73. For example, when the pressure roller 1 moves up, the distance between the driven gear 73 and the driving gear 72 of the two pressure rollers 1 increases. The transmission belt 71 squeezes the spring 74. The compression of the spring 74 causes the slider 75 to move towards the driving gear 72, so that the transmission belt 71 can always maintain an effective tension state and maintain the effective meshing between the driving gear 75 and the driven gear 72.

[0036] Furthermore, to ensure the secure installation of the roller pressing structure and the baking tray conveying device, the aforementioned locking buckle 10 includes a hook 100, a fixed base 101, a handle 102, and a retaining ring 103. The first end of the hook 100 has a first hook that engages with the baking tray conveying device, and the second end has a second hook that engages with the retaining ring 103. The fixed base 101 is mounted on the housing 9, and the handle 102 is rotatably connected to the fixed base 101. The handle 102 is hinged to the retaining ring 103. This configuration achieves a detachable design between the roller pressing structure and the baking tray conveying device, thus allowing adjustment of the roller pressing structure's position on the baking tray conveying device according to actual production conditions.

[0037] Furthermore, the aforementioned pressure roller 1 includes a rotating shaft and a roller sleeved and fixed to the rotating shaft, the roller being made of stainless steel.

[0038] Furthermore, the aforementioned roller pressing structure also includes a scraper (not shown) arranged along the axial direction of the pressure roller 1 and a collection trough (not shown) connected to the scraper. The scraper is in close contact with the roller surface of the pressure roller 1, and the two ends of the collection trough are connected to fixed plates 2. The collection trough is connected to a collection bucket. By scraping away the food residue adhering to the roller surface with the scraper, and after the pressure roller structure has been running for a period of time, the food residue on the collection trough is removed by a brush, further ensuring the quality of the bread produced.

[0039] Furthermore, the angle between the aforementioned scraper and the roller surface is 45°.

[0040] Furthermore, the above-mentioned roller pressing structure also includes a measuring scale, which is used to measure the horizontal height of the pressure roller 1. The measuring scale is vertically set on the housing 9 and located on one side of the turntable 8. The measuring scale is provided with millimeter-level graduations. When the turntable 8 is rotated, the current horizontal height of the pressure roller 1 can be determined by the measuring scale.

[0041] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
