Description

Technical Field

[0001] This utility model belongs to the technical field of toast sheet forming structure, and more specifically, it relates to a toast sheet forming structure and a toast shaping machine. Background Technology

[0002] Toast is a popular food among consumers. When eating it, you can first slice the toast, and then add jam, salad or other ingredients between two slices of toast. It is a very convenient and quick breakfast option.

[0003] In the process of forming toast, the dough is often rolled into sheets by multiple sets of pressure rollers. During the initial rolling, the dough is prone to slippage, and repeated rolling can cause the final sheet to deform or misalign. It is difficult to ensure that the sheet is effectively aligned with the central axis of the conveyor belt, which affects the dimensional accuracy of subsequent toast rolling and cutting. In severe cases, jamming may also occur, affecting the forming quality and efficiency of the toast. Utility Model Content

[0004] The purpose of this invention is to provide a toast sheet forming structure and a toast shaping machine that can deform the dough into strips and then into sheets, ensuring the forming quality and positional accuracy of the sheets.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a toast dough sheet forming structure is provided, including a frame, a first conveyor belt, a second conveyor belt, a rolling roller assembly, and a sheet rolling roller assembly. The first and second conveyor belts are connected to the frame, and the second conveyor belt is located below the discharge end of the first conveyor belt. The rolling roller assembly includes two forming rollers with main shafts connected to the frame in the vertical direction. The forming rollers are located above the first conveyor belt and have a gap between them. The two forming rollers rotate in opposite directions and are used to squeeze the dough from both sides to form a strip-shaped dough blank. The sheet rolling roller assembly includes a lower support roller and an upper pressure roller connected to the frame. The lower support roller and the upper pressure roller rotate in opposite directions and are used to roll the strip-shaped dough blank to form a dough sheet.

[0006] In one possible implementation, the lower part of the forming roller has a guide cone with a gradually increasing outer diameter, and the guide cones of the two forming rollers cooperate with each other to guide the dough to the center and form it into a strip-shaped dough blank.

[0007] In one possible implementation, the forming roller is connected to the frame via an adjustment assembly, which includes a lead screw, a lead nut, a guide rod, and an adjustment knob. The lead screw and the guide rod are connected to the frame in the left and right directions, respectively. The lead nut is threaded onto the lead screw and slides with the guide rod. The adjustment knob is connected to the outer end of the lead screw. The forming roller is connected below the lead nut and can move left and right synchronously with the lead nut under the action of the lead screw.

[0008] In one possible implementation, the upper pressure roller is located above and in front of the lower support roller, and the two ends of the upper pressure roller are respectively provided with outwardly extending mounting shafts. The inner side wall of the frame is provided with a mounting groove that extends forward and downward at an angle. The mounting shaft is locked in the mounting groove by a first locking member.

[0009] In one possible implementation, a rejection plate is connected to the frame, located in front of the upper pressure roller. The rear of the rejection plate is inclined downward toward the side closer to the upper pressure roller to guide the sheet away from the upper pressure roller.

[0010] In some embodiments, extension rods are provided at the left and right ends of the rejection plate, and mounting arc grooves for mounting the extension rods are provided on the inner side wall of the frame. The mounting arc grooves extend in an arc along the circumferential direction of the upper pressure roller, and the extension rods are locked in the mounting arc grooves by a second locking member.

[0011] In one possible implementation, a rejection roller located in front of the lower support roller is also rotatably connected to the frame. The rejection roller is located below the lower support roller and rotates in the same direction as the lower support roller to guide the sheet away from the lower support roller.

[0012] In some embodiments, a guide roller located below the front side of the rejection roller is also rotatably connected to the frame, the guide roller being used to guide the sheet onto the second conveyor belt.

[0013] In one possible implementation, the second conveyor belt is provided with a primary roll curtain located in front of the lower idler roller. The primary roll curtain is located in front of the rejecting roller and is used to guide the front edge of the sheet to roll backward to form a sheet roll. The rear edge of the primary roll curtain is connected to an adjusting crossbar. The frame is provided with two symmetrical support brackets located on both sides of the primary roll curtain. The support brackets are provided with several hanging slots spaced apart in the vertical direction. The two ends of the adjusting crossbar are respectively hooked into the hanging slots of the two support brackets.

[0014] Compared with the prior art, the toast sheet forming structure provided in this application embodiment utilizes a strip-rolling roller group and a sheet-rolling roller group to sequentially extrude the dough into strips and roll it into sheets. The dough is first extruded into strip-shaped dough blanks by the two forming rollers of the strip-rolling roller group on the first conveyor belt, and then sent to the lower support roller and upper pressure roller of the rolling roller group to be rolled into an oblong sheet, which facilitates subsequent rolling and other operations. The above-mentioned step-by-step forming method can not only improve the forming efficiency of toast sheets, but also facilitate the addition of layers generated by subsequent rolling, thereby helping to improve the forming quality of toast.

[0015] This utility model also provides a toast shaping machine, which includes a toast sheet forming structure.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a number" means two or more, unless otherwise explicitly specified.

[0026] Please refer to the following: Figures 1 to 5 The present invention will now describe the toast sheet forming structure and toast shaping machine provided by the present invention. The toast sheet forming structure includes a frame 1, a first conveyor belt 2, a second conveyor belt 3, a strip rolling roller group 4, and a sheet rolling roller group 5. The first conveyor belt 2 and the second conveyor belt 3 are connected to the frame 1, and the second conveyor belt 3 is located below the discharge end of the first conveyor belt 2. The strip rolling roller group 4 includes two forming rollers 41 whose main shafts are rotatably connected to the frame 1 in the vertical direction. The forming rollers 41 are located above the first conveyor belt 2 and have a gap between them. The two forming rollers 41 rotate in opposite directions and are used to squeeze the dough from both sides to form a strip-shaped dough blank. The sheet rolling roller group 5 includes a lower support roller 51 and an upper pressure roller 52 rotatably connected to the frame 1. The lower support roller 51 and the upper pressure roller 52 rotate in opposite directions and are used to roll the strip-shaped dough blank to form a dough sheet.

[0027] Compared with the prior art, the toast sheet forming structure provided in this embodiment utilizes the rolling roller group 4 and the rolling roller group 5 to sequentially extrude the dough into strips and roll it into sheets. The dough is first extruded into strip-shaped dough blanks by the two forming rollers 41 of the rolling roller group 4 on the first conveyor belt 2, and then sent to the lower support roller 51 and the upper pressure roller 52 of the rolling roller group to be rolled into an oblong sheet, which facilitates subsequent rolling and other operations. The above-mentioned step-by-step forming method can not only improve the forming efficiency of toast sheets, but also facilitate the addition of layers generated by subsequent rolling, thereby helping to improve the forming quality of toast.

[0028] In this embodiment, the rolling roller group 4 can shape the spherical dough into long strips of dough, which makes it easier to roll it into oblong sheets later. This results in more layers when the dough is rolled up, thus improving the texture after baking.

[0029] It should be noted that the two forming rollers 41 are symmetrically located on both sides of the central axis of the first conveyor belt 2. They not only have the function of shaping the dough, but more importantly, they can guide the dough to the central axis of the first conveyor belt 2, which is the middle position in the width direction. This facilitates the improvement of the positional accuracy of subsequent dough sheet and dough roll forming, and improves the overall forming quality of subsequent products.

[0030] Please refer to one possible implementation as well. Figures 1 to 5 The lower part of the forming roller 41 has a guide cone 42 with a gradually increasing outer diameter. The guide cones 42 of the two forming rollers 41 cooperate with each other to guide the dough to the center and form it into a strip-shaped dough blank. The guide cone 42 at the lower part of the forming roller 41 can help the dough to be squeezed into a long strip of dough with a circular cross section, ensuring the smooth passage of the strip-shaped dough blank and avoiding the strip-shaped dough blank from sticking and getting stuck at this position.

[0031] In one possible implementation, the forming roller 41 is connected to the frame 1 via an adjusting assembly 7. The adjusting assembly 7 includes a bidirectional lead screw 71, a lead screw nut 72, a guide rod 73, and an adjusting knob 74. The bidirectional lead screw 71 and the guide rod 73 are respectively connected to the frame 1 in the left and right directions. The lead screw nut 72 is threaded to the bidirectional lead screw 71 and slides with the guide rod 73. The adjusting knob 74 is connected to the outer end of the bidirectional lead screw 71. The forming roller 41 is connected below the lead screw nut 72 and can move left and right synchronously with the lead screw nut 72 under the action of the bidirectional lead screw 71.

[0032] In this embodiment, the distance between the two forming rollers 41 can be adjusted using the adjusting component 7 according to the size of the dough, thereby obtaining a long strip of dough with a suitable thickness. Specifically, rotating the adjusting knob 74 drives the bidirectional lead screw 71 to rotate. Under the limiting action of the guide rod 73, the lead screw nut 72 moves closer to or further away from each other along the axial direction of the bidirectional lead screw 71, thereby adjusting the distance between the two forming rollers 41 and ensuring effective alignment between the long strip of dough and the central axis of the first conveyor belt 2, meeting the subsequent shaping requirements.

[0033] Please refer to one possible implementation as well. Figures 1 to 5 The upper pressure roller 52 is located above the lower support roller 51 on the front side. The two ends of the upper pressure roller 52 are respectively provided with outwardly extending mounting shafts 53. The inner side wall of the frame 1 is provided with a mounting groove 11, which extends forward and downward at an angle. The mounting shaft 53 is locked in the mounting groove 11 by the first locking member 54.

[0034] In this embodiment, when installing the upper pressure roller 52, the mounting shaft 53 is locked in the mounting groove 11 by the first locking member 54. By adjusting the vertical position of the mounting shaft 53 in the mounting groove 11, it is convenient to roll strip blanks of different specifications and ensure good rolling quality.

[0035] Please refer to one possible implementation as well. Figures 1 to 5 A scraper plate 55 is connected to the frame 1, located in front of the upper pressure roller 52. The rear part of the scraper plate 55 is inclined downward towards the side closer to the upper pressure roller 52 to guide the dough sheet away from the upper pressure roller 52. When the lower support roller 51 and the upper pressure roller 52 are used to roll the strip-shaped dough blank, due to the large rolling pressure, a scraper plate 55 is also provided to prevent the dough sheet from sticking to the peripheral wall of the upper pressure roller 52. The scraper plate 55 is located on the lower front side of the upper pressure roller 52 and has an edge that can contact the peripheral wall of the upper pressure roller 52, so as to remove the dough sheet that is stuck to the upper pressure roller 52 and allow the dough sheet to fall smoothly and be conveyed to the next step.

[0036] In some embodiments, please refer to the following: Figures 1 to 5 The left and right ends of the ejector plate 55 are respectively provided with extension rods 56. The inner side wall of the frame 1 is provided with an installation arc groove 12 for installing the extension rods 56. The installation arc groove 12 extends in an arc along the circumferential direction of the upper pressure roller 52. The extension rods 56 are locked in the installation arc groove 12 by the second locking member 57.

[0037] In this embodiment, in order to ensure the rejection effect of the rejection plate 55 on the sheet, the rejection plate 55 needs to be able to move synchronously with the upper pressure roller 52. In addition, the rejection plate 55 should also be able to adjust its angle so that its plate surface is tangent to the peripheral wall of the upper pressure roller 52, thereby improving the removal efficiency of the sheet. Therefore, the extension rod 56 can be locked in the mounting arc groove 12 by means of the second locking member 57 to satisfy its rejection function.

[0038] Please see Figures 4 to 5 When structurally cutting the ejector plate 55 and the upper pressure roller 52, the cutting is performed along the central axis of the mounting groove 11 and the mounting arc groove 12 to more clearly reflect the mounting structure.

[0039] Please refer to one possible implementation as well. Figures 1 to 5 The frame 1 is also rotatably connected to a stripping roller 58 located in front of the lower support roller 51. The stripping roller 58 is located at the lower part of the lower support roller 51 and rotates in the same direction as the lower support roller 51, and is used to guide the sheet to detach from the lower support roller 51.

[0040] In this embodiment, while the stripper plate 55 peels the sheet off from the upper pressure roller 52, a stripper roller 58 is also provided to prevent the sheet from sticking to the peripheral wall of the lower support roller 51. The stripper roller 58 is located at the lower front side of the lower support roller 51, and the rotation direction of the stripper roller 58 is the same as the rotation direction of the lower support roller 51, so as to achieve the stripping effect on the sheet.

[0041] In some embodiments, please refer to the following: Figures 1 to 5A guide roller 6 is rotatably connected to the frame 1, located below the front side of the rejection roller 58. The guide roller 6 is used to guide the dough pieces onto the second conveyor belt 3. Through the guiding action of the guide roller 6, the dough pieces rejected by the rejection roller 58 from the lower support roller 51 can fall smoothly onto the second conveyor belt 3, meeting the requirements for smooth conveying of the dough pieces.

[0042] Please refer to one possible implementation as well. Figures 1 to 5 The second conveyor belt 3 is equipped with a primary roll curtain 8 located in front of the lower idler roller 51. The primary roll curtain 8 is located in front of the rejecting roller 58 and is used to guide the front edge of the sheet to roll backward to form a sheet roll. The rear edge of the primary roll curtain 8 is connected to an adjusting crossbar 81. The frame 1 is equipped with two symmetrical support brackets 13 located on both sides of the primary roll curtain 8. The support brackets 13 are equipped with several hanging slots 14 spaced apart in the vertical direction. The two ends of the adjusting crossbar 81 are respectively hooked into the hanging slots 14 of the two support brackets 13.

[0043] In this embodiment, the initial roll curtain 8, located in front of the lower roller 51, can block and limit the front edge of the sheet, thereby causing the sheet to initially form a winding trend. Then, under the overall action of the upper initial roll curtain 8 and the lower second conveyor belt 3, a continuous winding trend is formed, which meets the forming requirements of the sheet roll.

[0044] The front edge of the initial roller blind 8 is raised in height by adjusting the crossbar 81. The crossbar 81 is connected to the hanging slot 14 at the same height in the two support brackets 13 to ensure the consistency of the height on both sides of the initial roller blind 8. This avoids excessive friction between the rolled-up surface and the initial roller blind 8, thus ensuring that the surface can be smoothly conveyed forward for subsequent rolling and pressing steps. This further makes the surface forming more stable and facilitates subsequent cutting and reversing operations of the rolled-up surface.

[0045] Based on the same inventive concept, this application also provides a toast shaping machine, which includes a toast sheet forming structure. This toast shaping machine can sequentially extrude the dough into strips and roll it into sheets, thereby improving the efficiency of toast sheet forming and increasing the layers created during subsequent rolling, thus contributing to improved toast forming quality.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
