Description

Technical Field

[0001] This utility model relates to a noodle pressing machine. Background Technology

[0002] A dough press machine can replace manual labor in the dough pressing process of pasta making, saving time and effort. There are many types of pasta, and the requirements for dough pressing vary, primarily in the thickness of the resulting dough sheet. To control the dough thickness, existing dough press machines have corresponding adjustment functions. For example, Chinese patent CN215346722U, published on July 30, 2021, entitled "Adjustment Structure for the Gap of Dough Rollers in a Dough Press Machine," describes a first and second dough roller rotatably connected to a frame. Both ends of the second dough roller have sliders, which slide along the frame to change the gap between the second and first dough rollers. The sliders have teeth, and the frame has a rotating shaft with gears meshing with the teeth at both ends. The frame also has an adjustment component for controlling the slider's movement. Both sliders slide simultaneously in the same direction and distance. The adjustment component is matched with one of the gears; this adjustment component includes a worm gear structure and a rack and pinion structure. The spacing adjustment structure uses a worm gear structure as the power input end and a gear and rack structure as the power output end. In the existing technology, the entire spacing adjustment structure is designed to be installed in pieces on the frame. The assembly process of the spacing adjustment structure is included in the assembly process of the dough press machine, which requires the personnel to be proficient in more assembly content during the assembly process of the dough press machine, resulting in high assembly difficulty. Summary of the Invention

[0003] The technical problem to be solved by this invention is how to reduce the difficulty of the assembly process, thereby obtaining a dough press machine that is easy to assemble.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The dough press machine includes a frame, a movable pressure roller, a fixed pressure roller, and a spacing adjustment component. The movable pressure roller, fixed pressure roller, and spacing adjustment component are all mounted on the frame. The movable pressure roller is slidably mounted on the frame at both ends via sliding seats. The movable pressure roller is parallel to the fixed pressure roller. The spacing adjustment component is connected to the sliding seats and drives the movable pressure roller to move in the direction of changing the spacing with the fixed pressure roller. The spacing adjustment component is equipped with a series-connected drive module. The drive module includes a housing and a drive shaft. The drive shaft and driven shaft are movably mounted on the housing, which is fixedly mounted on the frame. The centerline of the drive shaft is perpendicular to the centerline of the driven shaft. The drive shaft has helical teeth, and the driven shaft has hobbing teeth. The drive shaft and driven shaft are connected by the meshing of the helical teeth and the hobbing teeth. The telescopic rod is movably connected to the driven shaft by a thread. One end of the telescopic rod is connected to a sliding seat, and the telescopic rod is stationary relative to the sliding seat in the circumferential direction around the centerline of the telescopic rod. The drive shafts of adjacent drive modules are connected by couplings.

[0005] The spacing adjustment component of the dough press machine adopts a modular design concept, achieving a synchronized and consistent spacing adjustment structure through a series connection. This modular design concept is reflected in the drive module; in this technical solution, the spacing adjustment structure is only implemented by the series-connected drive modules, and the drive shaft and driven shaft within the drive module are designed based on a worm gear structure. As mentioned earlier, the drive module integrates the transmission structure into the housing, achieving an integrated modular structure. Installation of the drive module is achieved through a fixed connection between the housing and the frame. The drive module does not need to be assembled during the dough press machine assembly; it can be produced separately at another location, at another time, and by other personnel. Personnel assembling the drive module only need to possess assembly skills specific to the drive module, while personnel assembling the dough press machine do not require such skills. This significantly reduces the assembly process difficulty of the dough press machine.

[0006] Compared to existing pitch adjustment structures that use a worm gear structure as the power input and a rack and pinion structure as the power output, this technical solution only involves a series drive module from the adjustment component. The drive shaft serves as the power input, and the driven shaft as the power output. In the former case, a parallel power transmission structure is required, forming a two-stage transmission mechanism with the worm gear structure at the power input. This technical solution, however, eliminates the need for such a parallel transmission structure; power is directly transmitted across the drive shafts without secondary distribution. Therefore, the power transmission path in this technical solution is shorter.

[0007] It should be added that in the existing technology, the spacing adjustment structure only has a worm gear structure at the power input end. Although the worm gear structure itself has a self-locking feature, meaning that power can only be transmitted unidirectionally from the worm to the worm, the transmission structure based on the gear and rack at the power output end is always affected by the assembly clearance, resulting in a relative range of motion. This power output end is a bidirectional transmission structure and does not have a self-locking function. Specifically, there is an assembly clearance between the teeth of the gear and rack, which allows the rack to have a small range of motion relative to the gear. That is, when the power output end is not outputting power, the gear and rack are stationary. Due to the aforementioned assembly clearance, the rack obtains a range of motion relative to the gear through the assembly clearance. Furthermore, this causes the distance between the first and second dough rollers to change, with the spacing being larger or smaller, resulting in the phenomenon of the second dough roller wobbling relative to the first dough roller. This is the reason why the dough thickness produced by the existing dough press machine is inconsistent after adjusting the dough thickness. In this technical solution, the main structure of the drive module is a worm gear structure, meaning the drive module itself has a self-locking function, i.e., unidirectional transmission. The telescopic rod and the driven shaft are connected by a threaded connection. The meshing degree of the threaded connection is much higher than that of the aforementioned straight gear connection. Therefore, once the spacing is adjusted, the drive module will not cause the movable pressure roller to wobble relative to the fixed pressure roller due to the assembly gaps found in existing technologies. After implementation, this technical solution achieves a consistent surface thickness.

[0008] When implementing a threaded connection between the telescopic rod and the driven shaft, the telescopic rod can be provided with an external thread and the driven shaft with an internal thread, and the telescopic rod and the driven shaft can be connected by the external thread and the internal thread; alternatively, the telescopic rod can be provided with an internal thread and the driven shaft with an external thread, and the telescopic rod and the driven shaft can be connected by the internal thread and the external thread.

[0009] The drive shaft of the drive module can be rotated manually or electrically. Manual operation includes directly using a wrench to clamp the drive shaft and then turning it; it also includes a manual component on the drive shaft for hand operation. Specifically, the spacing adjustment component includes a manual component fixedly mounted on one end of the drive shaft of one of the drive modules. This manual component can be a hand crank or a handwheel, and it is firmly fixed to the drive shaft. Electrical operation includes direct drive and split drive. Direct drive means that the electric component is directly and fixedly assembled with the drive shaft. Specifically, the spacing adjustment component also includes an electric component fixedly mounted on one end of the drive shaft of one of the drive modules. This electric component can be a motor or a combination of a motor and a reducer. The separate-drive method refers to a quick-release connection between the electric component and the drive shaft. Specifically, one end of the drive shaft of one of the drive modules of the spacing adjustment component has a non-centrally symmetrical cross-section, which can be a regular hexagon or a square. The electric component is a handheld drill. In use, a socket is attached to the handheld drill, and the socket has holes corresponding to the regular hexagon or square. One end of the drive shaft is embedded in the socket, and the handheld drill can then drive the drive shaft to rotate. After adjustment, the socket can be directly pulled off the drive shaft. Of course, in this separate-drive method, not only the electric component can be used, but also a hand crank or handwheel with a matching hole structure can be used. In use, simply align the hole on the hand crank or handwheel with the drive shaft and ensure that one end of the drive shaft is inserted into the hole. After the spacing adjustment is completed, the hand crank or handwheel can be directly pulled off the drive shaft.

[0010] The drive modules are connected in series using couplings. To further reduce the difficulty of the assembly process, at least two couplings are provided between adjacent drive modules, and adjacent couplings are connected by a drive shaft. This can significantly increase the capacity to accommodate redundancy with low machining and assembly precision, and helps to obtain more uniform and stable mechanical performance.

[0011] In existing technologies, the second dough roller is driven by a chain. When the second dough roller moves horizontally, the chain tension changes. Excessive tension increases the resistance to chain movement, preventing the second dough roller from rotating. Therefore, the range of motion of the second dough roller in existing technologies is limited by the chain drive effect, resulting in a small adjustment range for the spacing. The dough press machine in this technical solution also includes a synchronization component, comprising a first gear, a second gear, a third gear, and a fourth gear. The first gear is connected to the fixed pressure roller, and the fourth gear is connected to the movable pressure roller. The second and third gears are movably mounted on the frame. The first gear meshes with the second gear, the second gear meshes with the third gear, and the third gear meshes with the fourth gear. The centerline of the third gear is located directly below the sliding seat's range of motion on the frame. As long as the range of motion of the third gear's teeth always intersects with that of the fourth gear's teeth, the fourth gear can always be driven by the third gear, regardless of where the fourth gear moves with the movable pressure roller. Therefore, the synchronization component has an open transmission structure. When the distance between the movable pressure roller and the fixed pressure roller increases to the point that the movement range of the third gear tooth is out of the movement range of the fourth gear tooth, the movable pressure roller can still rotate. However, at this time, the working mode of the movable pressure roller has changed from active rotation to passive rotation. There will never be a situation where the movable pressure roller cannot rotate.

[0012] As is well known, dough exhibits non-Newtonian fluid properties. When dough passes through the area between the fixed and movable rollers, the high-speed rotation of the fixed and movable rollers creates an impact on the dough surface, resulting in friction. The greater the distance between the fixed and movable rollers, the more pronounced the friction. This is because the dough sheet formed at this point is thick and still exhibits significant non-Newtonian fluid properties. Therefore, it is necessary to maintain sufficient meshing between the third and fourth gears. For this purpose, the centerline of the third gear is located directly below one end of the sliding seat's range of motion on the frame. At this point, the distance between the movable and fixed rollers is at its maximum, and the third and fourth gears are in optimal meshing, sufficient to overcome friction and complete the dough pressing operation.

[0013] The present invention adopts the above-mentioned technical solution: the spacing adjustment component is set in a modular manner on the dough press, so the personnel assembling the dough press do not need to master the assembly skills of the drive module, which greatly reduces the difficulty of the dough press assembly process; moreover, the power transmission path of the spacing adjustment component is short, and the spacing between the movable pressure roller and the fixed pressure roller remains stable after the spacing is adjusted, so that dough sheets with uniform thickness can be obtained.

[0023] like Figures 1 to 8 As shown, the first embodiment of this utility model is an example.

[0024] The dough press machine includes a frame 1, a movable pressure roller 2, a fixed pressure roller 3, a spacing adjustment component, a synchronization component, and a main power motor.

[0025] The fixed pressure roller 3 is mounted on the frame 1 via bearings, and its position on the frame 1 is fixed. One end of the fixed pressure roller 3 is connected to the drive motor mounted on the frame 1 via a gear transmission structure. After the drive motor is started, it can drive the fixed pressure roller 3 to rotate.

[0026] The movable pressure roller 2 is slidably mounted on the frame 1 via sliding seats 17 at both ends. The movable pressure roller 2 and the sliding seats 17 are connected by bearings. The movable pressure roller 2 can not only rotate itself but also slide horizontally on the frame 1. The movable pressure roller 2 is parallel to the fixed pressure roller 3. Horizontal displacement of the movable pressure roller 2 can change the distance between it and the fixed pressure roller 3, such as... Figure 3 , 4As shown.

[0027] A synchronization assembly ensures that the movable pressure roller 2 rotates simultaneously when the fixed pressure roller 3 rotates. The synchronization assembly is located at the other end of the fixed pressure roller 3. The synchronization assembly includes a first gear 11, a second gear 12, a third gear 13, and a fourth gear 14. The first gear 11 is connected to the fixed pressure roller 3, and the fourth gear 14 is connected to the movable pressure roller 2. The second gear 12 and the third gear 13 are movably mounted on the frame 1, while their positions on the frame 1 remain fixed. The first gear 11 meshes with the second gear 12, and the meshing degree between them remains constant. The second gear 12 meshes with the third gear 13, and the meshing degree between them remains constant. Although the third gear 13 meshes with the fourth gear 14, the fourth gear 14 moves horizontally along with the movable pressure roller 2, causing the meshing degree between the third gear 13 and the fourth gear 14 to change with the distance between the movable pressure roller 2 and the fixed pressure roller 3. Since the centerline of the third gear 13 is located directly below the sliding seat 17's range of motion on the frame 1, and the centerline of the third gear 13 is located directly below one end of the sliding seat 17's range of motion on the frame 1, the distance between the movable pressure roller 2 and the fixed pressure roller 3 is at its maximum in this state. After the movable pressure roller 2 moves toward the position of the fixed pressure roller 3, the meshing degree between the third gear 13 and the fourth gear 14 will decrease. When the fixed pressure roller 3 rotates, it can drive the movable pressure roller 2 to rotate through the synchronization component, and the rotation direction of the fixed pressure roller 3 is opposite to the rotation direction of the movable pressure roller 2.

[0028] The spacing adjustment component is connected to the sliding seat 17 and drives the movable pressure roller 2 to move in the direction of changing the spacing with the fixed pressure roller 3. Therefore, the spacing adjustment component is used to drive the movable pressure roller 2 to move horizontally.

[0029] The spacing adjustment component is equipped with a series of drive modules 4. Each drive module 4 is a fully functional unit, including a housing 5, a drive shaft 6, a driven shaft 7, and a telescopic rod 8. The drive shaft 6 and driven shaft 7 are movably mounted on the housing 5. The drive shaft 6 is equipped with a bearing and is movably connected to the housing 5 via the bearing, allowing it to rotate on the housing 5 after installation. The driven shaft 7 is also equipped with a bearing and is movably connected to the housing 5 via the bearing, allowing it to rotate on the housing 5 after installation. After installation, the centerline of the drive shaft 6 is perpendicular to the centerline of the driven shaft 7. The drive shaft 6 has helical teeth, and the driven shaft 7 has hobbing teeth. The drive shaft 6 and driven shaft 7 are connected by the meshing of the helical teeth and hobbing teeth, thus connecting them through a worm gear structure. The rotation of the drive shaft 6 drives the rotation of the driven shaft 7, and only the drive shaft 6 can drive the driven shaft 7. Both ends of the drive shaft 6 are located outside the housing 5, and one end of the driven shaft 7 is located outside the housing 5. The outer casing is fixedly mounted on the frame 1 by bolts.

[0030] like Figure 5 As shown, the driven shaft 7 has a threaded hole with an internal thread. The telescopic rod 8 is cylindrical in shape, with a flange at one end and an external thread at the other. The flange has a non-centrally symmetrical cross-section, such as a regular hexagon. The sliding seat 17 has a groove 15 corresponding to the flanged end of the telescopic rod 8. The width of the groove 15 is less than the maximum width of the flange but greater than the minimum width of the flange. A limiting plate 16 is bolted to the sliding seat 17 and covers the groove 15. The limiting plate 16 has a notch for easy insertion of the telescopic rod 8. The width of the notch is less than the minimum width of the flange. Therefore, when the flanged end of the telescopic rod 8 is inserted into the groove 15, the telescopic rod 8 cannot rotate in the circumferential direction around its centerline or move along its centerline. This is equivalent to the telescopic rod 8 remaining stationary relative to the sliding seat 17 in the circumferential direction around its centerline after the flanged end is connected to the sliding seat 17.

[0031] The end of the telescopic rod 8 with an external thread is located in the threaded hole of the driven shaft 7. The telescopic rod 8 and the driven shaft 7 are connected by external and internal threads. When the driven shaft 7 rotates, it causes the telescopic rod 8 to move relative to the driven shaft 7, and the direction of movement coincides with the center line of the telescopic rod 8. The telescopic rod 8 can extend and retract on the drive module 4. The extension and retraction of the telescopic rod 8 can directly drive the sliding seat 17 to move, ultimately realizing the translation of the sliding seat 17 driven by the drive module 4, thereby adjusting the distance between the movable pressure roller 2 and the fixed pressure roller 3.

[0032] The spacing adjustment component includes two drive modules 4, which are arranged adjacently on both sides of the frame 1. The drive shafts 6 of the adjacent drive modules 4 are connected by two couplings 9, and the two couplings 9 are connected by a transmission shaft. A manual component 10, which is a hand crank, is installed at one end of the drive shaft 6 of one of the drive modules 4. The manual component 10 is fixedly connected to the drive shaft 6.

[0033] In use, simply operate the manual component 10 to make the drive shaft 6 rotate, and the telescopic rod 8 of the drive module 4 will move in a telescopic motion, thereby adjusting the distance between the movable pressure roller 2 and the fixed pressure roller 3.

One end of the drive shaft is inserted into the socket, and the handheld drill can drive the drive shaft to rotate. After adjustment, the socket can be directly pulled off the drive shaft. Alternatively, a hand crank or handwheel with a matching hole structure can be used. When in use, simply align the hole on the hand crank or handwheel with the drive shaft and ensure that one end of the drive shaft is inserted into the hole.
