Description

Technical Field

[0001] This utility model relates to the field of fried dough stick processing technology, specifically to an automatic fried dough stick forming production line. Background Technology

[0002] In the automated production of fried dough sticks, for example, during the processing of the dough, the noodles need to be stretched to a certain thickness before being cut into strips. Manually stretching the dough is not only time-consuming and labor-intensive but also inefficient. This inefficient stretching method increases production costs and may limit the expansion of production scale. Currently existing belt conveyors with dough stretching functions mostly achieve dough stretching by laterally rolling the dough with rollers. This method results in uneven lateral internal stress within the dough, making it prone to shrinkage after cutting, leading to product bending and deformation, ultimately affecting product quality. Furthermore, the lateral stretching degree is inconvenient to adjust, resulting in poor operational flexibility. Utility Model Content

[0003] This utility model provides an automatic dough stick forming production line to solve the technical problem in the prior art where the dough strip stretching equipment during dough stick processing results in uneven lateral stretching of the dough strip, affecting the product appearance and having poor flexibility of use.

[0004] To solve the above problems, the automatic dough stick forming production line provided by this utility model adopts the following technical solution:

[0005] The system includes a dough sheet rolling machine, a continuous dough sheet conveyor, a dough sheet cutting mechanism, and a fryer arranged in sequence. The fryer includes a frying pan and an automatic unloading mechanism. The continuous dough sheet conveyor includes a frame assembly. A lower dough pressing mechanism is provided on the frame assembly, and an upper dough pressing mechanism is provided above the lower dough pressing mechanism with a gap. The upper dough pressing mechanism is supported by an upper support plate, which is supported above the frame assembly by a height adjustment component.

[0006] Both the lower pressing mechanism and the upper pressing mechanism include a rotating shaft with a rotating support. A V-shaped pulley is provided on the rotating shaft, and a V-shaped belt is conveyed on the V-shaped pulley. The V-shaped belts are arranged at intervals, and the distance between adjacent V-shaped belts gradually increases from one end to the other. The conveying directions of the V-shaped belts in the lower pressing mechanism and the upper pressing mechanism are opposite. The side of the frame assembly is provided with a power component for driving the V-shaped belts in the lower pressing mechanism and the upper pressing mechanism to rotate.

[0007] The side of the V-belt pulley is provided with a positioning and mounting bushing. The positioning and mounting bushing moves along the axis of the rotating shaft to drive the V-belt pulley to move and adjust on the rotating shaft.

[0008] Furthermore, the height adjustment assembly includes a side connecting plate, the bottom of which is fixedly connected to the frame assembly and the upper part is vertically adjustable to the upper support plate.

[0009] Furthermore, the side connecting plate is provided with a waist hole opposite to the upper support plate.

[0010] Furthermore, the side of the side connecting plate is provided with an outwardly extending side wing plate, and the side of the upper support plate is provided with an adjustment plate opposite to the side wing plate. An adjustment bolt with threaded engagement is vertically inserted through the adjustment plate, and the bottom end of the adjustment bolt penetrates through the side wing plate.

[0011] Furthermore, the positioning and mounting bushing is provided with slots distributed along its axial direction, and the two free ends formed at the slots are fastened together by bolts.

[0012] Furthermore, in the lower pressing surface mechanism, the rotating shaft directly driven by the power component is the main power shaft, and in the upper pressing surface mechanism, the shaft opposite to the main power shaft is the auxiliary power shaft. Both the main power shaft and the auxiliary power shaft are provided with a transmission sprocket at the end away from the power component. The side of the upper support plate is rotatably supported by redirecting sprockets distributed on both sides of the transmission sprockets. The transmission sprockets and the redirecting sprockets are connected by a transmission chain.

[0013] Furthermore, in the lower pressing surface mechanism and the upper pressing surface mechanism, the rotating shaft at the end away from the power component is a tension adjustment shaft, and a tension adjustment component is provided on the side of the tension adjustment shaft.

[0014] Furthermore, both the frame assembly and the upper support plate are provided with adjustment slots opposite to the tension adjustment shaft. The tension adjustment shaft passes through the adjustment slots. The tension adjustment assembly includes a vertical plate fixed to one side of the adjustment slot. A tension bolt passes through the vertical plate laterally. The side of the tension adjustment shaft is provided with positioning holes opposite to the tension bolt.

[0015] The tensioning bolt is equipped with positioning nuts distributed on both sides of the vertical plate.

[0016] The beneficial effects of this utility model are:

[0017] 1. In this utility model, by gradually increasing the spacing between adjacent V-belts from one end to the other, the V-belts conveyed through them form a conveying structure that is wide at one end and narrow at the other. The strip that needs to be extended enters from the narrower end and flows out from the wider end, achieving automatic lateral extension. The strip gradually disperses and extends laterally during the transmission process, improving the forming effect after the strip is cut.

[0018] 2. In this utility model, the distance between the lower pressing mechanism and the upper pressing mechanism can be easily adjusted to obtain noodle strips of different thicknesses, thereby improving the flexibility of equipment use.

[0019] 3. In this invention, the spacing between adjacent V-belts is adjustable. By controlling and adjusting the spacing of the V-belts, the lateral extension width of the surface belt can be controlled and adjusted. This helps to meet different production needs. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0030] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0031] Example 1 of the automatic fried dough stick forming production line provided by this utility model:

[0032] like Figures 1 to 5 As shown, the system includes, in sequence, a dough sheet rolling machine (a), a continuous dough sheet conveyor (b), a dough sheet cutting mechanism (c), and a fryer. The fryer includes a frying pan (d) and an automatic unloading mechanism (e). The continuous dough sheet conveyor (b) includes a frame assembly (1), on which a lower dough pressing mechanism (2) is mounted. An upper dough pressing mechanism (3) is mounted on the lower dough pressing mechanism (2) with a gap, and the upper dough pressing mechanism (3) is supported by an upper support plate (4). The upper support plate (4) is supported above the frame assembly (1) by a height adjustment component (5). The frame assembly (1) has the lower dough pressing mechanism (2) mounted on it, and the upper dough pressing mechanism (3) is mounted on the lower dough pressing mechanism (2) with a gap, and the upper dough pressing mechanism (3) is supported by the upper support plate (4). Both the lower pressing mechanism 2 and the upper pressing mechanism 3 include a rotating shaft 21 with a rotating support. A V-shaped pulley 211 is provided on the shaft 21, and a V-shaped belt 212 is conveyed on the V-shaped pulley 211. Several V-shaped belts 212 are arranged at intervals, and the distance between adjacent V-shaped belts 212 gradually increases from one end to the other end. The conveying directions of the V-shaped belts 212 in the lower pressing mechanism 2 and the V-shaped belts 212 in the upper pressing mechanism 3 are opposite. The side of the frame assembly 1 is provided with a power component for driving the V-shaped belts 212 in the lower pressing mechanism 2 and the V-shaped belts 212 in the upper pressing mechanism 3 to rotate.

[0033] The coordinated action of the lower pressing mechanism 2 and the upper pressing mechanism 3 ensures that the dough strip is stretched evenly under force during transmission. The resulting V-shaped strips 212 are spaced apart with the spacing between adjacent strips gradually increasing, which helps the dough strip to gradually spread and stretch laterally during transmission, improving the forming effect after the dough strip is cut.

[0034] In practical use, after the dough is initially rolled by two dough rolling machines, it enters the continuous dough stretching conveyor b. Specifically, the dough that needs to be stretched enters from the narrower end and flows out from the wider end, achieving automatic lateral stretching.

[0035] After passing through the continuous stretching conveyor b, the dough strip enters the dough strip cutting mechanism c. The cut dough strips are then conveyed by a conveyor belt to the fryer d for frying. After frying, the strips are automatically removed from the fryer d by a coordinated automatic ejection mechanism. Subsequent packaging and other operations are then performed.

[0036] It should be noted that the dough rolling machine (a), the dough strip cutting mechanism (c), and the fryer are all existing technologies, so they will not be described in detail here.

[0037] In this embodiment, the upper support plate 4 is supported above the frame assembly 1 by the height adjustment component 5.

[0038] The height adjustment component 5 includes a side connecting plate 51, the bottom of which is fixedly connected to the frame assembly 1 and the upper part is vertically adjustable to the upper support plate 4.

[0039] The upper support plate 4 and the side connecting plate 51 are gradually vertically adjustable, enabling vertical adjustment of the upper pressing mechanism 3 supported by the upper support plate 4, and thus adjusting the distance between the lower pressing mechanism 2 and the upper pressing mechanism 3. Different distances between the lower pressing mechanism 2 and the upper pressing mechanism 3 can result in dough strips of different thicknesses, improving the flexibility of equipment use.

[0040] The side connecting plate 51 has a waist hole 511 opposite to the upper support plate 4. The waist hole 511 facilitates the adjustment of the relative fixed position of the upper support plate 4 and the side connecting plate 51. That is, the height of the upper support plate 4 can be adjusted while the height of the side connecting plate 51 remains unchanged.

[0041] The side of the side connecting plate 51 is provided with an outwardly extending side wing plate 512, and the side of the upper support plate 4 is provided with an adjustment plate 41 opposite to the side wing plate 512. An adjustment bolt 42 with threaded engagement is vertically inserted through the adjustment plate 41, and the bottom end of the adjustment bolt 42 passes through the side wing plate 512.

[0042] The ease of adjusting the upper support plate 4 is improved by adjusting bolt 42. When adjustment is required, first loosen the connecting bolt at the waist hole 511, and then rotate the adjusting bolt 42 to move the upper support plate 4 up or down relative to the side connecting plate 51, thereby achieving vertical adjustment of the upper pressure surface mechanism 3.

[0043] In this embodiment, a positioning and mounting bushing 23 is provided on the side of the V-belt pulley 211. The positioning and mounting bushing 23 moves along the axial direction of the rotating shaft 21 to drive the V-belt pulley 211 to move and adjust on the rotating shaft 21.

[0044] The positioning and mounting bushing 23 has grooves 231 distributed along its axial direction, and the two free ends formed at the grooves 231 are fastened together by bolts.

[0045] The V-belt pulley 211 moves and adjusts on the rotating shaft 21, driving the adjustment of the V-belt 212 that passes through it. This adjusts the spacing between adjacent V-belts 212, and by controlling the spacing of the V-belts 212, the lateral extension width of the belt can be controlled and adjusted. This helps to meet different production needs.

[0046] The two free ends at slot 231 are fastened together by bolts and nuts. For adjustment, first loosen the connection at slot 231. At this point, the positioning bushing 23 can move freely on the rotating shaft 21 for adjustment. After adjusting to the appropriate position, tighten the bolts and nuts at slot 231. Adjustment is quick and convenient.

[0047] In this embodiment, the main power shaft 24 in the lower pressing mechanism 2 is the rotating shaft 21 directly driven by the power component, and the auxiliary power shaft 31 is opposite to the main power shaft 24 in the upper pressing mechanism 3. Both the main power shaft 24 and the auxiliary power shaft 31 are provided with a transmission sprocket 32 ​​at the end away from the power component. The side of the upper support plate 4 is rotatably supported by redirecting sprockets 43 distributed on both sides of the transmission sprocket 32. The transmission sprocket 32 ​​and the redirecting sprocket 43 are connected by a transmission chain.

[0048] A single power component, namely a motor, drives the rotation of both the lower pressing mechanism 2 and the upper pressing mechanism 3. By cooperating with the redirecting sprocket 43, the transmission directions of the V-belt 212 in the lower pressing mechanism 2 and the V-belt 212 in the upper pressing mechanism 3 are reversed, ultimately achieving the output of the surface belt sandwiched between them in one direction.

[0049] In this embodiment, the rotating shaft 21 in the lower pressing surface mechanism 2 and the upper pressing surface mechanism 3, which is far from the power component, is a tension adjustment shaft 25, and a tension adjustment component is provided on the side of the tension adjustment shaft 25.

[0050] The frame assembly 1 and the upper support plate 4 are provided with adjustment transverse grooves 44 opposite to the tension adjustment shaft 25. The tension adjustment shaft 25 passes through the adjustment transverse grooves 44. The tension adjustment assembly includes a vertical plate 45 fixed to one side of the adjustment transverse groove 44. A tension bolt 46 passes through the vertical plate 45 laterally. The side of the tension adjustment shaft 25 is provided with positioning holes 251 opposite to the tension bolt 46.

[0051] The tensioning bolt 46 is provided with positioning nuts 461 distributed on both sides of the vertical plate 45.

[0052] After the lower pressing mechanism 2 and the upper pressing mechanism 3 have been running for a period of time, the V-belt 212 may become loose, affecting the overall stability of the structure and the service life of the equipment. At this time, it is necessary to adjust the tensioning bolt 46 to bring the V-belt 212 into a taut state. Specifically, by rotating the tensioning bolt 46, it moves towards the end closer to the tension adjustment shaft 25. Since one end of the tensioning bolt 46 extends into the side of the tension adjustment shaft 25, the tensioning bolt 46 will move within the adjustment groove 44 against the tension adjustment shaft 25. After adjustment, the positioning nut 461 can be used for auxiliary positioning.

[0053] Based on the above description in this specification, those skilled in the art will also understand that the following terms used, such as "upper," "lower," "front," "rear," "left," "right," "width," "horizontal," "top," "bottom," "inner," and "outer," are terms indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.

[0054] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
