Description

Technical Field

[0001] This utility model relates to the field of dough production technology, and in particular to a dough processing mechanism for stuffed foods. Background Technology

[0002] When rolling out dumpling wrappers by hand, the pressure of the rolling pin is controlled by hand to produce wrappers that are thicker in the middle and thinner at the edges. Hand-rolled wrappers result in dumplings with a better texture and do not break at the bottom during steaming or boiling. Therefore, in the production of dumpling wrappers on a machine assembly line, a pressing mechanism is used to mimic the hand-rolled wrapper in order to achieve the same texture as the dumplings.

[0003] A pressing mechanism for producing imitation handmade dumpling wrappers is disclosed in Chinese Patent CN203233955U, and an imitation handmade dumpling wrapper machine is disclosed in Chinese Patent CN115486468A. Both prior art technologies use the same principle for imitating handmade dumpling wrappers: feeding the dough strip between a forming roller and a pressing roller. The surface of the forming roller has multiple grooves that are deep in the center and thin at the edges. The pressing roller presses the dough strip into these grooves, thus forming the dough strip into a shaped dough strip with a thicker center and thinner edges, resembling an island. The shaped dough strip is then punched to produce imitation handmade dumpling wrappers with a thicker center and thinner edges, resembling an island. However, both prior art technologies still have the following drawbacks in use:

[0004] Among them, CN203233955U discloses a pressing mechanism for producing imitation handmade dumpling skin dough strips, which is equipped with two scraper plates, corresponding to the forming roller and the flat roller respectively. However, the surface of the forming roller is provided with grooves, and the dumpling skin part is located in the grooves. Therefore, when the scraper plates are attached to the surface of the forming roller, they cannot scrape off the dumpling skin in the grooves, and may even cause the dumpling skin part to be torn.

[0005] A simulated handmade dumpling skin machine disclosed in Chinese patent CN115486468A has a forming roller located above the pressing roller. The dough strip is scraped off the pressing roller by a scraper. However, the dumpling skin part in the groove of the forming roller will be adsorbed in the groove due to friction and air pressure. The dough strip is pulled out of the groove by gravity, which will cause the dumpling skin to be stretched and deformed, affecting the wrapping effect. Utility Model Content

[0006] The purpose of this utility model is to at least solve one of the technical defects described in the background art.

[0007] Therefore, one objective of this utility model is to provide a dough processing mechanism for stuffed food, which aims to solve the problem in the prior art that dumpling wrappers are easily scratched or stretched and deformed when processing dumpling wrappers in a simulated hand-made manner.

[0008] To achieve the above objectives, one embodiment of the present invention provides a dough processing mechanism for stuffed food, including a left vertical plate, a right vertical plate, a forming roller and a pressing roller. A support rod is installed between the left and right vertical plates. The forming roller and the pressing roller are rotatably connected between the left and right vertical plates. A transmission component connected to the forming roller and the pressing roller is provided on the outer side of the left vertical plate. Multiple grooves are provided on the outer surface of the forming roller.

[0009] An air knife and a support rod are installed between the left and right upright plates. A guide plate is installed at the air outlet of the air knife, and a scraper is installed on the support rod.

[0010] The beneficial effects are: the high-pressure air blown out by the air knife can separate the dough strip from the grooved surface of the forming roller without damage, and the scraper can scrape the dough strip off the flat pressing roller without damage, so the dumpling skin will not be torn or stretched and deformed.

[0011] Furthermore, one side of the left and right vertical plates is provided with adjustment components for adjusting the position of the pressing rollers.

[0012] A preferred embodiment is that a housing is installed on the left and right upright plates, with a feed inlet at the top of the housing and guide plates installed on both sides of the feed inlet.

[0013] The beneficial effects are: the shell wraps around the forming roller and the pressing roller, which can play a certain role in dust prevention, and the guide plate can accurately guide the dough strip between the forming roller and the pressing roller.

[0014] A preferred embodiment is that the outer surface of the forming roller has several anti-slip grooves.

[0015] In a further preferred embodiment, several anti-slip grooves are arranged laterally, parallel to the axis of the forming roller.

[0016] The beneficial effects are: when the dough enters the forming roller and pressing roller, the anti-slip grooves grip the dough, reducing the sliding displacement of the dough and thus avoiding the problem of transverse breakage of the dough.

[0017] In a further preferred embodiment, the outer surface of the forming roller is provided with multiple longitudinal anti-slip grooves, which are perpendicular to each other as well as the transverse anti-slip grooves.

[0018] The beneficial effect is that the longitudinal anti-slip grooves can reduce the displacement of the surface strip between the forming roller and the pressing roller towards the groove, thereby avoiding the problem of longitudinal cracks in the surface strip.

[0019] A preferred option is to design the anti-slip grooves in a V-shape.

[0020] The beneficial effects are as follows: the two sides of the V-shaped anti-slip groove are inclined, so when the dough belt enters between the forming roller and the pressing roller, the V-shaped anti-slip groove can grip the dough belt and play an anti-slip role. In addition, the inclined sides of the dough belt located between the forming roller and the pressing roller can also prevent the dough belt from shifting laterally, thus achieving the purpose of anti-slip in both the lateral and longitudinal directions at the same time, avoiding the problem of lateral breakage or longitudinal cracks in the dough belt.

[0021] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] This utility model provides a processing mechanism for dough for stuffed foods.

[0032] Example 1:

[0033] like Figure 1 As shown, it includes a left vertical plate 11, a right vertical plate 12, a forming roller 21, and a pressing roller 22. A support rod 13 is installed between the left vertical plate 11 and the right vertical plate 12, fixing the left vertical plate 11 and the right vertical plate 12 together with a fixed spacing. A central shaft is fixed at the axis of both the forming roller 21 and the pressing roller 22. The forming roller 21 and the pressing roller 22 are rotatably connected between the left vertical plate 11 and the right vertical plate 12 through the central shaft. A transmission assembly 3 is installed at one end of each of the two central shafts. The transmission assembly 3 includes two gears, which are respectively installed on the two central shafts and mesh with each other. By driving one of the central shafts to rotate using a drive assembly, both central shafts can be rotated simultaneously, thereby causing the forming roller 21 and the pressing roller 22 to rotate simultaneously. The transmission assembly 3 and the corresponding drive assembly are existing technologies and will not be described in detail in this application.

[0034] One side of the left vertical plate 11 and the right vertical plate 12 is provided with an adjustment component 4 for adjusting the position of the pressing roller 22. The adjustment component 4 can adjust the distance between the forming roller 21 and the pressing roller 22. The adjustment component 4 is prior art, and its specific structure will not be described in detail in this application.

[0035] The outer surface of the forming roller 21 has multiple grooves 23, with the center of the grooves 23 being deep and the edges being shallow. Thus, after the dough passes between the forming roller 21 and the pressing roller 22, the pressing roller 22 can press part of the dough into the grooves 23. The part inside the grooves 23 is the dumpling skin that is thick in the middle and thin at the edges.

[0036] like Figure 2As shown, an air knife 51 and a support rod 52 are installed between the left vertical plate 11 and the right vertical plate 12. The air knife 51 is connected to an air pump through a pipeline and can blow out high-pressure air. The air knife 51 is located below the forming roller 21, and the support rod 52 is located below the pressing roller 22. A guide plate 53 is installed at the air outlet of the air knife 51, and the end of the guide plate 53 faces the forming roller 21. Thus, the high-pressure air blown out by the air knife 51 can be blown towards the forming roller 21 through the guide plate 53. A scraper 54 is installed on the support rod 52, and the scraper 54 is elastic. The end of the scraper 54 is pressed against the surface of the pressing roller 22 by the rebound force. Thus, when the position of the pressing roller 22 is adjusted by the adjusting component 4, the scraper 54 can always stick to the surface of the pressing roller 22 through deformation and rebound, ensuring that the scraper 54 can always scrape off the dough strips pasted on the surface of the pressing roller 22.

[0037] like Figure 3 As shown, a housing 14 is installed on the left vertical plate 11 and the right vertical plate 12 to cover the top, front and rear sides and right side of the left vertical plate 11 and the right vertical plate 12, thereby wrapping the forming roller 21 and the pressing roller 22 and improving the dustproof effect. The top of the housing 14 is provided with a feed port 15, and guide plates 16 are installed on both sides of the feed port 15. When the dough is fed from the feed port 15, the dough can accurately enter between the forming roller 21 and the pressing roller 22 with the guide plates 16.

[0038] The working principle of this embodiment is as follows: In use, the forming roller 21 and the pressing roller 22 are driven to rotate, and then the dough is put into the feed port 15. The dough falls between the forming roller 21 and the pressing roller 22 with the guide plate 16. The pressing roller 22 presses part of the dough into the groove 23. After the dough passes through the forming roller 21 and the pressing roller 22, the high-pressure air blown out by the air knife 51 can separate the dough from the surface of the forming roller 21 with the groove 23 without damage. The scraper 54 can scrape the dough off the flat pressing roller 22 without damage. The formed dough with an island-shaped structure with a thick middle and thin periphery finally falls on the conveyor belt and is conveyed to the next process.

[0039] Because the dough has good extensibility, when the pressing roller 22 presses the dough into the groove 23 in the forming roller 21, the dough that has not yet entered the space between the pressing roller 22 and the forming roller 21 will quickly extend between the forming roller 21 and the pressing roller 22, causing the dough to slide between the pressing roller 22 and the forming roller 21. This may lead to the problem of transverse breakage of the dough. To solve this problem, this application proposes Embodiment 2:

[0040] like Figure 1-2 As shown, based on Embodiment 1, the outer surface of the forming roller 21 is provided with several transverse anti-slip grooves 24, so that when the dough enters the forming roller 21 and the pressing roller 22, the anti-slip grooves 24 grip the dough, reduce the sliding displacement, and thus avoid the problem of transverse breakage of the dough.

[0041] Because the dough has good extensibility, when the pressing roller 22 presses the dough into the groove 23 in the forming roller 21, the dough between the forming roller 21 and the pressing roller 22 quickly extends towards the groove 23. This causes the dough to slide between the pressing roller 22 and the forming roller 21, which may lead to longitudinal cracks in the dough. To solve this problem, this application proposes Embodiment 3:

[0042] like Figure 4 As shown, based on Embodiment 2, the outer surface of the forming roller 21 is provided with several longitudinal anti-slip grooves 24. The longitudinal anti-slip grooves 24 are perpendicular to each other with the transverse anti-slip grooves 24. The longitudinal anti-slip grooves 24 can reduce the displacement of the dough strip between the forming roller 21 and the pressing roller 22 towards the groove 23, thereby avoiding the problem of longitudinal cracks in the dough strip.

[0043] Because the dough has good extensibility, when the pressing roller 22 presses the dough into the groove 23 in the forming roller 21, the dough that has not yet entered the space between the pressing roller 22 and the forming roller 21 will quickly extend between the forming roller 21 and the pressing roller 22, and the dough between the forming roller 21 and the pressing roller 22 will quickly extend towards the groove 23. As a result, the dough will slide between the pressing roller 22 and the forming roller 21, which may lead to transverse breakage or longitudinal cracks in the dough. To solve this problem, this application proposes Embodiment 4:

[0044] like Figure 5 As shown, based on Embodiment 1, the outer surface of the forming roller 21 is provided with several V-shaped anti-slip grooves 24. The two sides of the V-shaped anti-slip grooves 24 are inclined, so that when the dough enters between the forming roller 21 and the pressing roller 22, the V-shaped anti-slip grooves 24 can grip the dough and play an anti-slip role. In addition, the inclined sides of the dough located between the forming roller 21 and the pressing roller 22 can also prevent the dough from lateral displacement, thus playing the purpose of lateral and longitudinal anti-slip at the same time, avoiding the problem of lateral breakage or longitudinal cracks in the dough.
