Description

Technical Field

[0001] This invention relates to the field of yogurt pressing machine technology, and in particular to a dry yogurt pressing machine. Background Technology

[0002] Dry-pressed yogurt is a dairy product made by pressing to remove some of the whey from yogurt, increasing its solids content and creating a firmer texture. In the processing of dry-pressed yogurt, fermented yogurt is typically placed into a filter bag, and then pressure is applied to the yogurt in the filter bag using a pressing mechanism, forcing the whey through the filter bag and thus completing the dehydration and pressing process.

[0003] Existing dry yogurt pressing equipment typically requires manual labor to place the folded filter bag into the tank and open it, and then close the bag opening after feeding. This involves many steps and a high degree of manual intervention, which increases the number of manual operations and affects processing efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dry yogurt pressing machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A dry yogurt pressing machine includes a machine body, in which multiple outer barrels are arranged, and an inner barrel is embedded in the outer barrels. The inner wall of each inner barrel is vertically provided with a toothed rack. A filter bag is installed inside the inner barrel, and the top of the filter bag is provided with a drawstring, and the top of the drawstring is provided with an elastic elastic opening. The top cover is located on the top of the outer barrel and moves laterally via guide rails. Each top cover has a pressing plate that extends into the inner barrel to press the yogurt. A feeding pipe that passes through the pressing plate is also fixedly installed on the top cover. The movable ring is installed inside the inner barrel and moves vertically. Multiple transmission boxes are fixedly installed on the outer side of the movable ring. Each transmission box has an external input gear that meshes with a rack on its outer side, and an internal output gear on its inner side. The lower rotating ring is rotatably mounted on the movable ring via a bearing mechanism. An upper rotating ring is vertically movably arranged above the lower rotating ring and rotates synchronously with it. The outer side wall of the upper rotating ring is provided with transmission teeth that mesh with the inner output gear. The tightening and loosening opening is assembled between the lower rotating ring and the upper rotating ring and rotates synchronously with them to achieve the twisting and closing of the bag.

[0006] In addition, the preferred structure is that the guide rails are fixedly installed on both sides of the machine body, and the top cover is fixedly installed with a mounting bracket that moves synchronously with it. The cylinders are all installed on the top of the top cover and fixed by the mounting bracket. The piston rods of the cylinders pass downward through the top cover and are fixedly connected to the pressing plate. The feeding pipe is fixedly assembled at the bottom of the mounting bracket.

[0007] In addition, a preferred structure is that the bottom of the top cover is provided with a storage groove for storing the pressing plate and the feeding tube, the bottom of the pressing plate is provided with a top groove, the top groove is adapted to the movable ring, the upper rotating ring and the lower rotating ring, and the pressing plate is provided with a through cavity for the feeding tube to pass through.

[0008] In addition, in a preferred configuration, multiple support seats are fixedly provided on the top of each of the movable rings, and the transmission box is fixedly installed at the end of each support seat.

[0009] In addition, a preferred structure is that the inner wall of the inner barrel is provided with an inner groove vertically, the rack is provided at the upper part of the inner groove, and the transmission box is guided to move through the inner groove.

[0010] In addition, a preferred structure is that silicone locking blocks are provided on both sides of the upper part of the inner groove, and locking grooves that are adapted to them are provided on the transmission box.

[0011] In addition, in a preferred configuration, a convex ring is fixedly provided at the bottom of the movable ring, and both the upper and lower rotating rings are sleeved on the movable ring and rotate. The lower rotating ring is rotatably connected to the movable ring through a bearing at the top of the convex ring, and a smooth surface that contacts the movable ring is provided on the inner wall of the upper rotating ring.

[0012] In addition, a preferred structure is that the inner wall of the lower rotating ring is provided with an inner cavity, and a plurality of vertical guide members are fixedly provided in the inner cavity.

[0013] In addition, a preferred structure is that an outer ring is fixedly provided at the bottom of the upper rotating ring, the outer ring moves vertically within the inner cavity, and a guide cavity adapted to the guide member is provided on the outer ring.

[0014] Furthermore, in a preferred configuration, the lower rotating ring has a top slope surface with a female friction groove on the top slope surface, the upper rotating ring has a bottom slope surface with a female friction groove on the bottom slope surface, the tightening and loosening opening is fitted into the gap between the top slope surface and the bottom slope surface, and the lower rotating ring has an outer slope surface located outside the top slope surface.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] See Figure 1-2 A dry yogurt pressing machine includes a machine body 1. Multiple outer barrels 12 are arranged side-by-side inside the machine body 1. An inner barrel 13 is embedded within each outer barrel 12 to hold yogurt and facilitate filtration and dehydration. A filter bag 14 is fitted inside the inner barrel 13. The top of the filter bag 14 has a constriction opening 141, and the top of the constriction opening 141 also has an elastic tightening opening 142. Through the elastic deformation of the tightening opening 142, it is easy to fit and install the bag between an upper rotating ring 4 and a lower rotating ring 5.

[0020] Guide rails 11 are fixedly installed on both sides of the machine body 1, and a top cover 2 is correspondingly installed on the top of the outer barrel 12. The top cover 2 can move laterally via the guide rails 11, allowing it to switch back and forth between an operating position directly above the outer barrel 12 and on one side of the machine body 1, facilitating the user's assembly and removal of components such as the bag 14. It is worth noting that the guide rail 11 moving mechanism is existing technology, and therefore will not be described in detail.

[0021] See Figure 3-5 A mounting bracket 21 is fixedly installed on the top cover 2 and moves synchronously therewith. A cylinder 22 is fixedly installed on the mounting bracket 21. The piston rod of the cylinder 22 passes downward through the top cover 2 and is fixedly connected to the pressing plate 221. The cylinder 22 can drive the pressing plate 221 to move vertically within the inner barrel 13 to press the yogurt in the bag 14. A feeding pipe 23 is also fixedly installed at the bottom of the mounting bracket 21. The feeding pipe 23 is vertically inserted into the cavity 223 opened on the pressing plate 221 to fill the bag 14 with yogurt.

[0022] It is worth noting that the feeding pipe 23 only moves horizontally in sync with the top cover 2 and the mounting bracket 21, and does not move vertically in sync with the pressing plate 221. That is, when the pressing plate 221 moves downward to press, the feeding pipe 23 always remains in its original position, and the feeding pipe 23 is connected to the external feeding mechanism through a corrugated pipe.

[0023] The bottom of the top cover 2 is provided with a storage groove for accommodating the pressing plate 221 and the feeding pipe 23, so as to avoid interference with the external structure when the top cover 2 moves laterally. The bottom of the pressing plate 221 is provided with a top groove 222, which is used to accommodate the movable ring 3, the upper rotating ring 4 and the lower rotating ring 5, and to provide them with clearance space.

[0024] See Figure 6-10An inner groove 131 is vertically formed on the inner wall of the inner barrel 13, and a rack 132 is fixedly installed on the upper part of the inner groove 131. Silicone locking blocks 133 are fixedly installed on both sides of the upper part of the inner groove 131, and a locking groove 333 adapted to the silicone locking block 133 is provided on the transmission box 33.

[0025] The movable ring 3 can move vertically within the inner barrel 13. Multiple support seats 32 are fixedly installed on the top of the movable ring 3, and a transmission box 33 is fixedly installed at the end of each support seat 32. The transmission box 33 moves along the inner groove 131 with the movable ring 3. An external input gear 331 is provided on the outer side of the transmission box 33, and an internal output gear 332 is provided on the inner side of the transmission box 33.

[0026] It is worth noting that the internal structure of the transmission box 33 can employ existing transmission structures such as helical gear sets, worm gears, or sprockets and chains to achieve the transmission connection between the external input gear 331 and the internal output gear 332. The number of meshing teeth and module between the rack 132 and the external input gear 331, the transmission ratio between the external input gear 331 and the internal output gear 332 inside the transmission box 33, and the torque required for the meshing transmission between the internal output gear 332 and the transmission gear 43 can all be adapted to the working conditions, such as the distance and speed of the downward movement of the movable ring 3. The specific selection of the number of gear teeth, module, and torque matching method are all existing technologies that can be implemented by those skilled in the art based on existing gear transmission design principles; therefore, they will not be elaborated upon in this embodiment.

[0027] See Figure 11-16 A protruding ring 31 is fixedly provided at the bottom of the movable ring 3. The upper rotating ring 4 and the lower rotating ring 5 are both sleeved on the movable ring 3 and can rotate relative to the movable ring 3. The lower rotating ring 5 is rotatably connected to the movable ring 3 through a bearing at the top of the protruding ring 31. The bearing seat and the bearing are existing technologies, so they will not be described in detail.

[0028] The inner wall of the upper rotating ring 4 is provided with a smooth surface 41 that fits against the outer wall of the movable ring 3, so that the upper rotating ring 4 can rotate smoothly or move vertically relative to the movable ring 3.

[0029] The lower rotating ring 5 has an inner cavity 51 on its inner wall, and multiple vertical guide members 511 are fixedly installed inside the inner cavity 51. An outer ring 42 is fixedly installed at the bottom of the upper rotating ring 4. The outer ring 42 is located within the inner cavity 51 and can move vertically. A guide cavity 421 adapted to the guide members 511 is provided on the outer ring 42. Through the cooperation of the guide members 511 and the guide cavity 421, the upper rotating ring 4 can slide vertically relative to the lower rotating ring 5 while also rotating synchronously with the lower rotating ring 5. A transmission tooth 43 is provided on the outer wall of the upper rotating ring 4. The transmission tooth 43 is adapted to mesh with the inner output gear 332 of the transmission box 33 to drive the upper rotating ring 4 to rotate.

[0030] The lower rotating ring 5 has a top slope surface 52 with a female friction groove 521 on it. The upper rotating ring 4 has a bottom slope surface 44 with a female friction groove 441 that matches the female friction groove 521 on it. The lower rotating ring 5 also has an outer slope surface 53 located outside the top slope surface 52. The elastic opening 142 of the sleeve 14 is fitted into the gap between the top slope surface 52 and the bottom slope surface 44. The outer slope surface 53 facilitates the easy insertion of the elastic opening 142 into the gap. Through the mutual adaptation of the female friction groove 521 and the female friction groove 441, the elastic opening 142 can be frictionally limited, allowing it to rotate synchronously with the upper rotating ring 4 and the lower rotating ring 5.

[0031] In this embodiment, before pressing the yogurt, the user first places the elastic opening 142 on the bag 14 between the lower rotating ring 5 and the upper rotating ring 4. Guided by the outer slope 53, the elastic opening 142 smoothly fits into the gap between the top slope 52 and the bottom slope 44, and is frictionally fixed by the female friction groove 521 and the female friction groove 441. During the placement of the elastic opening 142, the upper rotating ring 4 moves upward to make room. After the elastic opening 142 is placed, the upper rotating ring 4 moves to the top, and the elastic opening 142 is squeezed between the top slope 52 and the bottom slope 44.

[0032] Subsequently, the user aligns and inserts the transmission box 33 into the inner groove 131 of the inner barrel 13, ensuring that the silicone locking blocks 133 are engaged in the locking grooves 333. This completes the installation of the movable ring 3, the upper rotating ring 4, the lower rotating ring 5, and the bag 14. At this point, the top cover 2 can be controlled to move laterally back to directly above the outer barrel 12 via the guide rail 11, aligning the pressing plate 221 and the feeding pipe 23 with the inner barrel 13.

[0033] At this point, yogurt can be poured into the bag 14 through the feeding pipe 23 to open the bag 14. Then, the pressing plate 221 is moved downward by the cylinder 22. At this time, the movable ring 3, the upper rotating ring 4, and the lower rotating ring 5 can enter the top groove 222 at the bottom of the pressing plate 221 and move downward synchronously with the pressing plate 221. During this process, the silicone locking block 133 is subjected to downward pressure and falls out of the locking groove 333, so that the movable ring 3, the upper rotating ring 4, and the lower rotating ring 5 can move downward.

[0034] At this time, the transmission box 33 moves down along the inner groove 131. When the external input gear 331 on the transmission box 33 contacts and meshes with the rack 132 on the upper part of the inner groove 131, the external input gear 331 rotates under the transmission action of the rack 132, and transmits the rotation to the inner output gear 332 through the transmission box 33. This drives the transmission gear 43 meshing with the inner output gear 332 to rotate, causing the upper rotating ring 4 to rotate. Since the upper rotating ring 4 rotates synchronously with the lower rotating ring 5 through the cooperation of the guide member 511 and the guide cavity 421, the lower rotating ring 5 also rotates synchronously, thereby driving the tightening opening 142 clamped between the top slope surface 52 and the bottom slope surface 44 to rotate together. At this time, since the main body of the bag 14 cannot rotate due to gravity, the rotation of the tightening opening 142 can twist and close the closing opening 141 of the bag 14, thereby realizing the automatic closing of the bag 14.

[0035] Furthermore, after the pressing plate 221 moves down to the transmission box 33 and passes the area where the rack 132 is located, the upper rotating ring 4 and the lower rotating ring 5 stop rotating. The pressing plate 221 continues to move down along the inner groove 131 to press and dehydrate the yogurt in the closed bag 14, so that the whey is discharged through the bag 14.

[0036] Furthermore, a mutually compatible adsorption mechanism is provided between the support base 32 and the pressing plate 221. When the pressing plate 221 moves upward to reset, the adsorption mechanism can drive the movable ring 3, the upper rotating ring 4, and the lower rotating ring 5 to move upward synchronously until the locking groove 333 on the transmission box 33 re-engages with the silicone locking block 133. It is worth noting that the adsorption mechanism, the silicone locking block 133, and the locking groove 333 are all existing technologies. They can all be selected or replaced with other structures with the same function according to actual needs. For example, the adsorption mechanism can be set as a magnet, electromagnet, air plate adsorption, etc., and the silicone locking block 133 can be set as a snap-lock, friction lock, etc., which will not be elaborated here.

[0037] During the upward repositioning of the pressing plate 221, the transmission box 33 passes through the rack 132 area above the inner groove 131 again, causing the external input gear 331 to rotate in the opposite direction. This, in turn, drives the upper rotating ring 4 and the lower rotating ring 5 to rotate in the opposite direction, causing the tightening opening 142 to rotate in the opposite direction as well. This releases the torsion on the closing opening 141 of the bag 14, allowing the bag 14 to reopen. When the silicone locking block 133 re-enters the locking groove 333, the adsorption mechanism releases its adsorption. The specific release method can be adapted according to the type of adsorption mechanism selected. The movable ring 3, the upper rotating ring 4, and the lower rotating ring 5 are then relocked in the inner barrel 13.

[0038] After the pressing plate 221 is fully reset, the top cover 2 is moved laterally along the guide rail 11 away from the outer barrel 12. At this time, the user can remove the movable ring 3, the upper rotating ring 4, the lower rotating ring 5 and the bag 14 from the inner barrel 13 for cleaning or replacement, so as to carry out the next assembly and pressing operation.

[0039] In this invention, the pressing process of dry yogurt can be achieved through the outer barrel 12, the inner barrel 13 and the pressing plate 221. Through the linkage between the feeding pipe 23, the movable ring 3, the upper rotating ring 4 and the lower rotating ring 5, the yogurt can be automatically fed into the bag 14 to expand it. During the pressing process of the pressing plate 221, the twisting and closing of the bag 14's closing opening 141 is automatically completed, reducing manual operation steps and improving the processing efficiency of dry yogurt.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
