Description

Technical Field

[0001] This utility model relates to the technical field of dough press products, specifically a manual dough press. Background Technology

[0002] As we all know, hand-pulled noodles are clean, hygienic, healthy, and nutritious. However, hand-pulled noodles are generally made by kneading flour into a dough, then repeatedly rolling it out on a board with a rolling pin to make a thin sheet of dough, which is then cut into strips and cooked. Rolling out the dough requires a lot of effort, and sometimes the dough may not be uniform, resulting in noodles that are dry and not very palatable.

[0003] For example, a manual dough press machine with application number CN201520900466.7 is disclosed. Its structure includes: a support frame; a rack slidably mounted on the support frame; a pressing hammer fixedly connected to the bottom end of the rack; a pressing groove mounted on the support frame, with the pressing hammer engaged within the pressing groove; a rack shaft rotatably supported on the support frame via bearings, and meshing with the rack; and a pressing arm fixedly connected to the rack shaft. Existing equipment lacks a limiting design for the dough tray, causing the dough to easily shift and affecting operational convenience. Therefore, there is an urgent need for a manual dough press machine with a simple structure, requiring less effort to operate, and capable of stably pressing uniform dough. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide a manual dough sheeter that, through optimized transmission structure and limiting design, solves the problems of laborious operation, uneven dough distribution, and dough slippage in existing equipment.

[0005] According to this utility model, a manual dough sheeter includes a base plate, a material tray mounted on the upper surface of the base plate, a support rod fixed to the base plate, a housing mounted on the support rod, a pressure rod inside the housing, teeth on the surface of the pressure rod, one end of the pressure rod passing through the upper surface of the housing, the other end of the pressure rod passing through the lower surface of the housing and connected to a pressure plate, a limit washer mounted on the top of the pressure rod, a spring sleeved on the pressure rod, a protrusion on the front surface of the housing, a bearing mounted in the inner cavity of the protrusion, a rotating shaft inserted into the bearing, one end of the rotating shaft extending into the housing, a gear mounted on the extension of the rotating shaft, the gear meshing with the teeth, and a pull rod mounted on the other end of the rotating shaft.

[0006] The front and rear edges of the tray are respectively provided with limiting flanges, which extend from the edge of the base plate to the bottom surface of the base plate.

[0007] The base plate is equipped with positioning posts, the height of which is higher than the upper surface of the material tray.

[0008] Specifically, the surface of the pressure rod is provided with a keyway, and a guide key is provided inside the housing, with the guide key placed inside the keyway.

[0009] Furthermore, the material tray is provided with a handle on its side.

[0010] Furthermore, the surface of the support rod is provided with at least one reinforcing member, and the lower surface of the reinforcing member is welded to the upper surface of the base plate.

[0011] Specifically, the top end of the pressure rod is connected to the limiting washer via a first screw.

[0012] Furthermore, the surface of the housing is provided with a recess, one end of which extends to the edge of the housing.

[0013] Specifically, a ball head is installed at one end of the pull rod.

[0014] Specifically, the rotating shaft is equipped with a second screw, which rests against the surface of the pull rod.

[0015] The beneficial effects of this utility model are as follows.

[0016] 1. This structure uses gears and teeth to form a gear and rack transmission pair structure, which, together with the spring return mechanism, allows the user to drive the pressure plate to complete the pressing action by applying only a small force when pulling the lever. The compression and rebound characteristics of the spring ensure that the pressure plate returns to its original position quickly, improving the overall operating efficiency by more than 40% and significantly reducing manpower consumption.

[0017] Second, the front and rear edges of the material tray are equipped with limiting flanges, which, combined with the double limiting structure of the positioning column, effectively prevent the dough from shifting; the gap tolerance between the pressing plate and the surface of the material tray is controlled within ±0.5mm, ensuring that the dough thickness uniformity error is ≤1mm, thus improving the quality of the finished product.

[0018] 3. The support rod and the base plate are connected by T-shaped reinforcing parts. The casing and the support rod adopt an embedded fastening design, which increases the overall bending strength by 30% and can withstand a maximum pressure of 500N, extending the service life of the equipment to more than 10 years.

[0019] Fourth, the ball end of the pull rod matches the recess in the machine housing, meeting ergonomic grip requirements; the side handle of the material tray facilitates pulling operation, reducing the risk of dough sticking and improving ease of use.

[0020] 5. The guide key is placed in the keyway. The keyway guides the guide key and prevents the pressure rod from rotating due to accidental contact during the pressing of the pressure plate, thus preventing the gear from disengaging from the teeth. Attached Figure Description

Detailed Implementation

[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 are only used to explain this utility model, and should not be construed as limiting this utility model.

[0030] The following is for reference. Figures 1 to 6 A manual dough press machine according to an embodiment of the present invention includes a base plate 1, a material tray 2 mounted on the upper surface of the base plate 1, a support rod 3 fixed to the base plate 1, a housing 5 mounted on the support rod 3, a pressure rod 4 provided inside the housing 5, the surface of the pressure rod 4 having teeth 406, one end of the pressure rod 4 passing through the upper surface of the housing 5, the other end of the pressure rod 4 passing through the lower surface of the housing 5 and connected to a pressure plate 402, a limit washer 403 mounted on the top of the pressure rod 4, a spring 404 sleeved on the pressure rod 4, a protrusion 502 provided on the front surface of the housing 5, a bearing 9 installed in the inner cavity of the protrusion 502, a rotating shaft 6 inserted into the bearing 9, one end of the rotating shaft 6 extending into the housing 5, a gear 10 mounted on the extension of the rotating shaft 6, the gear 10 meshing with the teeth 406, and a pull rod 7 mounted on the other end of the rotating shaft 6.

[0031] The base plate 1 is a rectangular metal plate with mounting holes at its four corners. Plastic gaskets are bolted to the bottom surface of the base plate 1. The housing 5 is fixed to the support rod 3, and the inner wall of the housing 5 is tightly connected to the support rod 3. The pressure rod 4 is connected to the limiting washer 403 via a first screw 401. A spring 404 is sleeved on the outside of the pressure rod 4, with its bottom end pressing against the top surface of the housing 5 and its top end pressing against the limiting washer 403, providing a restoring force. The bottom end of the pressure rod 4 is welded to the pressure plate 402, which has a smooth surface. The rotating shaft 6 is installed in the inner cavity of the protrusion 502 of the housing 5 via a bearing 9. One end of the rotating shaft 6 extends into the housing 5 and is fitted with a gear 10. The rotating shaft 6 and the gear 10 are connected by a pin; the gear 10 meshes with the teeth of the pressure rod 4. The outer end of the rotating shaft 6 is fixed to the pull rod 7 via a second screw 601. For example, the spring 404 has an elastic modulus of 500 N / m, is made of high carbon steel, has a hardness of HRC45-50, a compression stroke of 20 mm, and can perform a reset function.

[0032] In addition, the gear 10 has a module of 2 and a number of teeth of 20, which meshes with the teeth of the pressure rod 4 (module 2, number of teeth 40) to form a transmission ratio of 2:1, so that the pressure plate 402 can be driven to complete the pressing action by lightly pulling the pull rod 7. The parameters of gear 10 are as follows: number of teeth (Z1): 20; pitch circle diameter (D1): Z1 × m = 40 mm; pressure angle: 20° (standard pressure angle, ensuring smooth meshing); material: 45# steel, surface hardened (hardness HRC45-50); tooth width: 10 mm (ensuring contact strength); The parameters of the rack part of the pressure rod 4 are as follows: number of teeth (Z2): 40 (meshing with gear 10); pitch circle diameter (D2): Z2 × m = 80 mm; tooth profile: spur teeth, matching gear 10; material: same as gear 10, ensuring wear resistance; transmission ratio (i): i = Z2 / Z1 = 40 / 20 = 2:1. When the user pulls the lever 7, gear 10 rotates one revolution, and the teeth drive the pressure rod 4 to move a distance of 2 modules (i.e., 4 mm). This transmission ratio balances the operating force and stroke requirements, and works with the spring to implement the reset function, achieving labor-saving operation.

[0033] During operation, when the dough press machine is pressing the dough, parchment paper is placed on both the top and bottom surfaces of the dough. The dough, wrapped in parchment paper, is then placed on the upper surface of the material tray 2, and the tray, along with the dough, is sent to the bottom of the pressing plate 402. Pulling the lever 7 downward causes the gear 10 to drive the pressing rod 4 downward counterclockwise. At this time, the spring 404 is compressed, and the pressing plate 402 presses the dough, ensuring that the dough is evenly stressed until it is pressed into a thin pancake of the specified thickness. After releasing the lever 7, the spring 404 pushes the pressing rod 4 back to its original position, and the pressing rod 4 drives the pressing plate 402 upward, lifting the pressing plate 402 off the dough, thus completing one pressing operation.

[0034] Comparative experiments showed that this dough press requires 60% of the operating force of a traditional dough press, and the standard deviation of dough thickness uniformity is reduced from 1.5mm to 0.8mm. Furthermore, after 20 repeated tests, the dough thickness error remained stable within ±0.5mm, and the support rod 3 did not deform under 500N pressure. Additionally, accelerated aging tests (equivalent to a 10-year service life) showed that the welding strength between the support rod 3 and the reinforcing component 301 remained ≥280MPa, with no fatigue cracks observed.

[0035] The material tray 2 described in this structure has a handle 201 on its side. The material tray 2 and the handle 201 are integrally formed, which facilitates pulling and placing the dough. When making the material tray 2, a cross or circular scale can be processed in the center of the material tray 2. The center of the scale corresponds to the center of the pressing plate 402. This makes it easy for people to accurately place the dough in the pressing center of the pressing plate 402, avoiding uneven pressure on the pressing plate due to misalignment between the dough and the center of the pressing plate 402, which would cause the dough to be pressed unevenly and become uneven in thickness. At the same time, the scaled material tray also makes it easy for the operator to know the size of the pressed pancake-shaped dough. The material tray 2 of this structure has limiting flanges 202 on its front and rear edges. The limiting flanges 202 extend downward from the edge of the base plate 1 to the bottom surface of the base plate 1, forming a U-shaped limiting groove to prevent the material tray 2 from moving back and forth. They also guide the material tray 2 to enter along the left side of the base plate 1. The material tray 2 can move left and right on the upper surface of the base plate 1. The material tray 2 detaches from the base plate 1 from the left side. A mark is provided at the center of the upper surface of the material tray 2 to facilitate the placement of dough in the center of the material tray 2 and prevent the dough from overflowing to the edge of the material tray 2.

[0036] The support rod 3 of this structure has at least one reinforcing member 301 on its surface, and the lower surface of the reinforcing member 301 is welded to the upper surface of the base plate 1. In this embodiment, three reinforcing members 301 are used, and the three reinforcing members 301 are distributed in a T-shape on the base plate 1 to enhance the bending resistance of the support rod 3.

[0037] The top end of the pressure rod 4 in this structure is connected to the limiting washer 403 by a first screw 401. The top end of the pressure rod 4 is provided with a screw hole, and the first screw 401 passes through the limiting washer 403 and is screwed into the screw hole, thereby fixing the limiting washer 403.

[0038] The surface of the housing 5 in this structure is provided with a recess 501, one end of which extends to the edge of the housing 5, making it convenient to grip the recess 501. Additionally, one end of the pull rod 7 in this structure is equipped with a ball head 701 for easy gripping.

[0039] The rotating shaft 6 of this structure is equipped with a second screw 601. The second screw 601 abuts against the surface of the pull rod 7 to fix the position of the pull rod 7 and prevent it from falling off the rotating shaft 6. In addition, the rotating shaft 6 is provided with a socket, and the pull rod 7 is inserted into the socket.

[0040] The pressure rod 4 of this structure has a keyway 405 on its surface, and a guide key 503 is provided inside the housing 5. The guide key 503 is fixed to the inner wall of the housing 5 and is placed in the keyway 405, which guides the guide key 503. When the gear 10 meshes with the teeth 406, the guide key 503 and the keyway 405 work together to prevent the pressure rod 4 from rotating due to accidental contact during the pressing of the pressure plate 402, and to prevent the gear 10 from disengaging from the teeth 406. Therefore, the guide key 503 and the keyway 405 work together to provide effective guidance and positioning.

[0041] like Figure 6 As shown, the base plate 1 of this structure is equipped with positioning posts 8, the height of which is higher than the upper surface of the material tray 2. The positioning posts 8 are vertically welded to the base plate 1 to limit the position of the material tray 2 and ensure uniform pressing.

[0042] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
