Description

Technical Field

[0001] The present invention relates to the technical field of wine mashing, in particular to a wine mashing device and a wine mashing method thereof. Background Art

[0002] Grape crushing is a crucial step in the winemaking process, directly impacting the efficiency of juice extraction during subsequent fermentation, the quality of the juice, and the taste and flavor of the final wine. Grapes need to be separated from the juice after crushing. However, the grape pulp can clog the discharge port for the separated mixture, affecting the efficiency of the crushing machine.

[0003] Patent publication number CN222574603U discloses a grape crushing device for making wine, which screens the crushed pulp through a filter rod, picks out the pulp screened by the filter rod again through a picking rod, and then discharges the pulp from the inside of the crushing bin through a discharge door. The juice produced by the crushing is collected through a collecting trough, thereby preventing the pulp produced by the crushing from clogging the device, thereby improving the efficiency of the device in crushing grapes and improving practicality.

[0004] Although the above solution can process the pulp in the gap between adjacent filter rods, the pulp on the filter rod that does not exceed the range of the filter rod cannot be picked out by the picking rod. When the filter rod is rotated vertically downward, the pulp may still fall into the juice, and some pulp may remain attached to the filter rod for a long time, causing the filter rod to be contaminated. When the juice passes through the contaminated filter rod again, it will also be contaminated. Summary of the Invention

[0006] In order to solve the problems of the prior art, the present invention provides a mashing device for wine production, comprising a mashing mechanism and a separation mechanism arranged at the lower end of the mashing mechanism, the separation mechanism comprising a vertically arranged main shaft and a separation unit arranged on the main shaft, the separation unit comprising an outer cover body arranged outside the main shaft, a filter screen and a flip connection structure; the interior of the outer cover body is sequentially provided with four workstations of separation, first cleaning, second cleaning and sterilization around the main shaft, and the four workstations are respectively provided with a separation pipe, a first cleaning structure, a second cleaning structure and a sterilization structure; the filter screen is horizontally located inside the separation pipe at the separation workstation; the flip connection structure connects the main shaft with the filter screen, and the flip connection structure changes the state of the filter screen following the rotation of the main shaft, so that the posture of the filter screen at each workstation is different.

[0009] Preferably, the flip structure includes a horizontally arranged active intermittent gear and a vertically arranged driven intermittent gear; the active intermittent gear is coaxial with the main shaft and is rotationally connected; the driven intermittent gear is coaxial with the rotating shaft and is fixedly connected, and the driven intermittent gear is intermittently meshed with the active intermittent gear.

[0010] Preferably, the flip structure also includes a toggle assembly, which includes a baffle rod parallel to the rotating shaft and a toggle plate connected to the active intermittent gear; one end of the baffle rod is connected to the driven intermittent gear, and the other end of the baffle rod extends toward the middle of the active intermittent gear; the toggle plate rotates around the axis of the main shaft following the active intermittent gear.

[0011] Preferably, the toggle assembly also includes a connecting seat and a reset rod; the connecting seat is connected to the active intermittent gear; one end of the reset rod is connected to the toggle plate axis, the other end of the reset rod passes through the connecting seat, and the other end of the reset rod is sleeved with a first reset spring, and the two ends of the first reset spring are respectively abutted against the end of the connecting seat and the reset rod.

[0012] Preferably, the flip connection structure further includes a horizontal stabilizing structure, which includes a rectangular docking assembly arranged at one end of the rotating shaft and a horizontally arranged stabilizing plate.

[0013] Preferably, the rectangular docking assembly includes a mounting plate and at least four rollers; the mounting plate is connected to the end of the rotating shaft; the four rollers are all arranged parallel to the rotating shaft, and the four rollers are installed on the mounting plate in a matrix shape.

[0014] Preferably, the horizontal stabilizing structure further includes an adaptive downward pressure assisting component, which is connected to the stabilizing plate and is used to apply a downward force along the main axis to the stabilizing plate.

[0015] A mashing method for a wine-producing mashing device, applied to a wine-producing mashing device, comprises the following steps:

[0016] S1, after the crushing mechanism crushes the grapes, the pulp and juice fall into the separation mechanism;

[0017] S2. Inside the separation mechanism, the pulp and juice fall along the separation pipe onto the filter screen, the pulp remains on the filter screen, and the juice continues to flow downward;

The combination of the separation pipe and the filter realizes the separation of pulp and juice, ensuring the purity of the juice. The flip connection structure enables the filter to automatically adjust its posture according to the rotation of the main shaft. The conversion of the filter from horizontal to vertical and then to horizontal not only avoids the filter from obstructing the movement of the pulp during the cleaning process, but also greatly improves the working efficiency and quality of the second cleaning structure by changing the direction of the filter so that the side with the pulp attached faces downward. After cleaning is completed, the filter is rotated to the sterilization station. The sterilization structure performs a comprehensive sterilization treatment on the surfaces of both sides of the filter, effectively eliminating possible microbial contamination and ensuring the hygienic standards of subsequent separation operations. The flip connection structure controls the filter to switch its posture in different stations, so that the filter can contact the first cleaning structure and the second cleaning structure in a posture that is more convenient for cleaning the pulp, thereby achieving efficient cleaning of the pulp attached to the surface of the filter and preventing the pulp from adhering to the filter and contaminating the juice.

DETAILED DESCRIPTION

[0036] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Reference Figures 1 to 10 As shown: A mashing device for wine production includes a mashing mechanism and a separation mechanism arranged at the lower end of the mashing mechanism, the separation mechanism includes a vertically arranged main shaft 1 and a separation unit arranged on the main shaft 1, the separation unit includes an outer cover body 2 covered on the outside of the main shaft 1, a filter screen 3 and a flip connection structure 4; the interior of the outer cover body 2 is sequentially provided with four stations of separation, first cleaning, second cleaning and sterilization around the main shaft 1, and the four stations are respectively provided with a separation pipe 5, a first cleaning structure 6, a second cleaning structure 7 and a sterilization structure 8; the filter screen 3 is located inside the separation pipe 5 at the level of the separation station; the flip connection structure 4 connects the main shaft 1 with the filter screen 3, and the flip connection structure 4 changes the state of the filter screen 3 following the rotation of the main shaft 1, so that the posture of the filter screen 3 at each station is different.

[0038] The separation pipe 5, the first cleaning structure 6, the second cleaning structure 7 and the sterilization structure 8 are all prior art. After the crushing mechanism crushes the grapes, the pulp and juice fall into the separation mechanism under the action of gravity. Inside the separation mechanism, the pulp and juice fall along the separation pipe 5 to the filter 3. The pulp is blocked by the filter 3 and remains on the horizontal filter 3, while the juice will continue to flow downward through the filter 3 to separate the pulp from the juice. When the filter 3 carries more pulp, the main shaft 1 starts to rotate, and the main shaft 1 drives the filter 3 to rotate synchronously around the axis of the main shaft 1 through the flip connection structure 4. At the same time, when the filter 3 rotates to the first cleaning station, the flip connection structure 4 gradually changes the filter 3 from a horizontal state to a vertical state. At this time, the filter 3 will not hinder the movement of the pulp. Under the action of gravity, it falls from the filter screen 3, completing the preliminary cleaning of the filter screen 3, and then the main shaft 1 continues to rotate, and the filter screen 3 rotates to the second cleaning station. At this time, the flip connection structure 4 gradually changes the filter screen 3 from a vertical state to a horizontal state, and the two rotation directions of the filter screen 3 are consistent, so that the side of the filter screen 3 originally carrying the pulp is facing downward, which is convenient for the second cleaning structure 7 to deeply clean the pulp attached to the filter screen 3. The main shaft 1 rotates again, and the main shaft 1 drives the filter screen 3 to rotate horizontally to the sterilization station. The sterilization structure 8 sterilizes the surfaces of both sides of the filter screen 3. Finally, the main shaft 1 drives the filter screen 3 to return to the separation station to prepare for a new round of separation operations, thereby achieving efficient cleaning of the pulp attached to the surface of the filter screen 3 and preventing the pulp from adhering to the filter screen 3 and contaminating the juice.

[0039] Reference Figure 2 and Figure 3 As shown, there are at least four separation units, and the filter screens 3 in the four separation units are located in four different working positions.

[0040] If the number of separation units is set to at least four, the waiting time of the filtration process will be increased. Specifically, when the separation mechanism contains only one separation unit, the separation pipe 5 needs to wait for the filter 3 to pass through three different working positions before the filter 3 can return to the separation pipe 5. If the number of separation units is two, the separation pipe 5 needs to wait for the filter 3 to pass through two working positions before the filter 3 can return to the separation pipe 5. When the number of separation units is three, the separation pipe 5 needs to wait for the filter 3 to pass through one working position before the filter 3 can return to the separation pipe 5. There is no filter 3 partition in the separation pipe 5. In this case, the mashed pulp and juice mixture will fall directly. To ensure that the mixture can be continuously blocked by the filter 3, the separation mechanism needs to be equipped with at least four separation units, and the filter 3 of the four separation units is in a different working state. As the main shaft 1 rotates, the four filter screens 3 will synchronously follow the main shaft 1 to rotate, realizing the synchronous transformation of the states of the four filter screens 3. By configuring at least four separation units, it is ensured that during the rotation of the main shaft 1, at least one filter screen 3 is always in the separation position, thereby realizing continuous separation of the mixture and avoiding efficiency loss caused by waiting for the filter screen 3 to return to the separation position.

[0041] Reference Figure 3 and Figure 5 As shown: The flip connection structure 4 includes a rotating shaft 41 and a flip structure 42; one end of the rotating shaft 41 passes vertically through the main shaft 1, and the axis of the rotating shaft 41 intersects with the axis of the main shaft 1, and the other end of the main shaft 1 is connected to the filter 3; the flip structure 42 is arranged on one side of the rotating shaft 41, and the flip structure 42 is used to drive the rotating shaft 41 to rotate around its own axis.

[0042] If the filter 3 only follows the main shaft 1 to rotate around the axis of the main shaft 1, the side of the filter 3 used to carry the pulp is always facing. When cleaning the side of the filter 3 used to carry the pulp, the surface of the filter 3 will always hinder the movement of the pulp, making it inconvenient to clean the filter 3. Therefore, a rotating shaft 41 and a flip structure 42 are provided. When the main shaft 1 rotates, the flip structure 42 drives the rotating shaft 41 to rotate, and the flip structure 42 controls the rotation speed of the rotating shaft 41. When the main shaft 1 rotates 90 degrees, the filter 3 moves to the first cleaning station. At this time, the flip structure 42 drives the rotating shaft 41 to rotate 90 degrees, and the rotating shaft 41 drives the filter 3 to flip 90 degrees, so that the filter 3 is turned from a horizontal state to a vertical state. Then the main shaft 1 rotates 90 degrees for the second time. 0 degrees, the filter 3 moves to the second cleaning station. At this time, the flipping structure 42 drives the rotating shaft 41 to continue to rotate 90 degrees, and the rotating shaft 41 drives the filter 3 to change from a vertical state to a horizontal state. At this time, the surface of the side of the filter 3 originally used to carry the pulp is facing downward. Then the main shaft 1 rotates 90 degrees for the third time, and the flipping structure 42 stops driving the rotating shaft 41 to rotate, so that the filter 3 maintains a horizontal posture and moves to the sterilization structure 8. After the sterilization is completed, the main shaft 1 rotates 90 degrees for the fourth time. At this time, the flipping structure 42 drives the rotating shaft 41 to rotate 180 degrees, and flips the side of the filter 3 used to carry the pulp to face upward, so that the filter 3 re-enters the separation pipe 5, thereby realizing the flipping and cleaning of the filter 3, which significantly improves the cleaning efficiency and cleanliness.

[0043] Reference Figure 5 and Figure 6 As shown: the flip structure 42 includes a horizontally arranged active intermittent gear 421 and a vertically arranged driven intermittent gear 422; the active intermittent gear 421 is coaxial with the main shaft 1 and is rotationally connected; the driven intermittent gear 422 is coaxial with the rotating shaft 41 and is fixedly connected, and the driven intermittent gear 422 is intermittently meshed with the active intermittent gear 421.

[0044] When the main shaft 1 rotates, the main shaft 1 drives the active intermittent gear 421 to rotate, the active intermittent gear 421 drives the driven intermittent gear 422 to rotate, and the driven intermittent gear 422 drives the rotating shaft 41 to rotate. When the main shaft 1 rotates 90 degrees for the first time, the active intermittent gear 421 is meshed with the driven intermittent gear 422. When the main shaft 1 rotates 90 degrees for the second time, the active intermittent gear 421 is meshed with the driven intermittent gear 422. When the main shaft 1 rotates 90 degrees for the third time, the active intermittent gear 421 is separated from the driven intermittent gear 422. When the main shaft 1 rotates 90 degrees for the fourth time, the active intermittent gear 421 is meshed with the driven intermittent gear 422. When the main shaft 1 rotates 90 degrees for the third time, the active intermittent gear 421 and the driven intermittent gear 422 are engaged, so that the rotating shaft 41 does not rotate during this process, so that the filter screen 3 can enter the sterilization structure 8 horizontally, effectively avoiding the problem of large vertical space occupation caused by the filter screen 3 vertically entering the sterilization structure 8, and also eliminating the need for the sterilization structure 8 to use an additional drive to move and cover the filter screen 3. Through the cooperation of the active intermittent gear 421 and the driven intermittent gear 422, the rotational movement of the main shaft 1 and the rotational movement of the rotating shaft 41 are linked, without the need for additional configuration of a driving device to drive the rotating shaft 41 separately, thereby realizing the linkage mechanism between the main shaft 1 and the rotating shaft 41.

[0045] Reference Figure 6 and Figure 7 As shown: the flip structure 42 also includes a toggle assembly 423, which includes a blocking rod 4231 parallel to the rotating shaft 41 and a toggle plate 4232 connected to the active intermittent gear 421; one end of the blocking rod 4231 is connected to the driven intermittent gear 422, and the other end of the blocking rod 4231 extends toward the middle of the active intermittent gear 421; the toggle plate 4232 rotates around the axis of the main shaft 1 following the active intermittent gear 421.

[0046] In the process of the main shaft 1 driving the active intermittent gear 421 to rotate, the active intermittent gear 421 needs to drive the driven intermittent gear 422 to complete two 90-degree rotations, a 0-degree stop and a 180-degree rotation in a specific order. In particular, in the stage of driving the driven intermittent gear 422 to rotate 180 degrees, the active intermittent gear 421 itself only rotates 90 degrees, which is not enough to directly complete the action. Therefore, it is necessary to use the toggle assembly 423 to achieve supplementary drive. When the filter screen 3 is horizontally placed inside the sterilization structure 8, the toggle plate 4232 rotates with the active intermittent gear 421. When the main shaft 1 completes the third 90-degree rotation and is ready to rotate for the fourth time, the toggle plate 423 2 gradually approaches the stop rod 4231. When the main shaft 1 starts to rotate 90 degrees for the fourth time, the toggle plate 4232 comes into contact with the stop rod 4231 and applies a driving force along its tangential direction to the driven intermittent gear 422 through the stop rod 4231. This driving force causes the driven intermittent gear 422 to first rotate 90 degrees independently. At this time, the driving intermittent gear 421 re-engages with the driven intermittent gear 422 that has rotated 90 degrees. Subsequently, the driving intermittent gear 421 continues to rotate the remaining 90 degrees, driving the driven intermittent gear 422 to complete the remaining 90 degrees of rotation. Therefore, during the entire process of the main shaft 1 rotating 90 degrees for the fourth time, the driven intermittent gear 422 is rotated a total of 180 degrees.

[0047] Reference Figure 6 and Figure 7 As shown: the toggle assembly 423 also includes a connecting seat 4233 and a reset rod 4234; the connecting seat 4233 is connected to the active intermittent gear 421, and the toggle plate 4232 is hinged to the connecting seat 4233; one end of the reset rod 4234 is axially connected to the toggle plate 4232, and the other end of the reset rod 4234 passes through the connecting seat 4233, and the other end of the reset rod 4234 is sleeved with a first reset spring 4235, and the two ends of the first reset spring 4235 are respectively abutted against the end of the connecting seat 4233 and the reset rod 4234.

[0048] When the toggle plate 4232 pushes the baffle rod 4231 to move, the baffle rod 4231 moves in the tangential direction of the rotation of the toggle plate 4232 and moves along the toggle plate 4232 away from the active intermittent gear 421. If the toggle plate 4232 is fixedly connected to the active intermittent gear 421, the movement of the toggle plate 4232 and the baffle rod 4231 may interfere with each other, affecting the movement of the baffle rod 4231. By providing a connecting seat 4233 and a reset rod 4234, and providing a first reset spring 4235 on the reset rod 4234, the reaction force exerted by the baffle rod 4231 on the toggle plate 4232 will cause the toggle plate 4232 to rotate around the hinge between it and the connecting seat 4233, so that the toggle plate 4232 The interference of rod 4231 is reduced. At the same time, when the toggle plate 4232 rotates, the reset rod 4234 and the connecting seat 4233 are driven to move relative to each other. The connecting seat 4233 squeezes the first reset spring 4235. The first reset spring 4235 stores elastic potential energy. When the toggle plate 4232 is out of contact with the baffle rod 4231, the first reset spring 4235 releases the elastic potential energy. The elastic potential energy acts on the reset rod 4234, causing the reset rod 4234 to pull the toggle plate 4232 to reset. Through the movement of the toggle plate 4232, the interference of the toggle plate 4232 on the movement of the baffle rod 4231 is effectively reduced, thereby ensuring that the baffle rod 4231 and the driven intermittent gear 422 connected thereto can achieve smoother and more stable rotation.

[0049] Reference Figure 3 and Figure 8 As shown, the flip connection structure 4 further includes a horizontal stabilizing structure 43 , which includes a rectangular docking assembly 431 arranged at one end of the rotating shaft 41 and a horizontally arranged stabilizing plate 432 .

[0050] When the main shaft 1 rotates for the third 90 degrees, the active intermittent gear 421 and the driven intermittent gear 422 are not engaged. Since the vibration of the rotation of the main shaft 1 will be transmitted to the rotating shaft 41, the rotating shaft 41 may still rotate. Therefore, a rectangular docking component 431 and a horizontal stabilizing plate 432 are provided. The rectangular docking component 431 has four continuous surfaces. When the rotating shaft 41 rotates, the rotating shaft 41 drives the rectangular docking component 431 to rotate. The four continuous surfaces on the rectangular docking component 431 rotate to the horizontal upward in turn, and the horizontally provided stabilizing plate 432 contacts the surface of the rectangular docking component 431. Since there is a large overlapping area between the surface of the rectangular docking component 431 and the stabilizing plate 432, the vibration force acting on the rotating shaft 41 is limited by the contact between the stabilizing plate 432 and the rectangular docking component 431, thereby ensuring that the filter screen 3 can maintain a stable posture during the horizontal displacement process and avoiding the occurrence of deflection.

[0051] Reference Figure 8 and Figure 9As shown: the rectangular docking assembly 431 includes a mounting plate 4311 and at least four rollers 4312; the mounting plate 4311 is connected to the end of the rotating shaft 41; the four rollers 4312 are all arranged parallel to the rotating shaft 41, and the four rollers 4312 are installed on the mounting plate 4311 in a matrix shape.

[0052] If the rectangular docking assembly 431 is in the shape of a quadrangular prism, then when the rectangular docking assembly 431 rotates with the rotating shaft 41, the edges of the rectangular docking assembly 431 will come into contact with the stabilizing plate 432, and sliding friction will occur between the two. The contact area between the two is small, resulting in a large friction force between the two. During the long-term rotation of the rectangular docking assembly 431, both the rectangular docking assembly 431 and the stabilizing plate 432 will wear out. Therefore, at least four rollers 4312 are provided, and the four rollers 4312 are mounted in a matrix on the mounting plate 4311. When the stabilizing plate 432 comes into contact with one of the rollers 4312, the force applied by the stabilizing plate 432 to the roller 4312 is transmitted to the rotating shaft 41 through the mounting plate 4311. , causing the rotating shaft 41 to rotate, and at the same time, another roller 4312 on the mounting plate 4311 will move toward the stabilizing plate 432 and eventually contact the stabilizing plate 432. At this time, two rollers 4312 are in contact with the stabilizing plate 432 at the same time, so that both sides of the rotating shaft 41 are subjected to forces of equal magnitude and the same direction. Therefore, the rotating shaft 41 will not rotate, and the main shaft 1 drives the rotating shaft 41 to rotate, and rolling friction occurs between the roller 4312 and the stabilizing plate 432. The friction coefficient of rolling friction is small, and the contact area between the roller 4312 and the stabilizing plate 432 is large, so that the friction force between the roller 4312 and the stabilizing plate 432 is small, thereby avoiding wear of the rectangular docking assembly 431 and the stabilizing plate 432.

[0053] Reference Figure 8 and Figure 10 As shown, the horizontal stabilizing structure 43 further includes an adaptive downward pressure assisting component 433 , which is connected to the stabilizing plate 432 . The adaptive downward pressure assisting component 433 is used to apply a downward force along the main axis 1 to the stabilizing plate 432 .

[0054] Specifically, the adaptive downward pressure assist assembly 433 includes a connecting plate 4331 and at least two connecting rods 4332. The connecting plate 4331 is fixedly connected to the main shaft 1, and the connecting plate 4331 is parallel to the stabilizing plate 432. The two connecting rods 4332 are both slidably connected to the connecting plate 4331, and one end of the connecting rod 4332 is connected to the stabilizing plate 432. The two connecting rods 4332 are both provided with a second return spring 4333, and the two ends of the second return spring 4333 are respectively connected to the connecting plate 4331 and the stabilizing plate 432.

[0055] When the stabilizing plate 432 contacts the two rollers 4312, the distance between the stabilizing plate 432 and the axis of the rotating shaft 41 is the shortest. When the rotating shaft 41 drives the rectangular docking assembly 431 to rotate, the rollers 4312 will exert an upward force on the stabilizing plate 432 along the axis of the main shaft 1, causing the stabilizing plate 432 to move away from the rotating shaft 41. At this time, the stabilizing plate 432 pushes the connecting rod 4332 and the connecting plate 4331 to slide relative to each other, and the second return spring 4333 is compressed. When the line connecting the rotating shaft 41 and the rollers 4312 is perpendicular to the stabilizing plate 432, the stabilizing plate 432 The distance between the stabilizing plate 432 and the rotating shaft 41 is the largest, and then the roller 4312 continues to rotate around the axis of the rotating shaft 41. At this time, the stabilizing plate 432 moves toward the rotating shaft 41 under the push of the second return spring 4333 until the stabilizing plate 432 contacts the two rollers 4312 again, and the second return spring 4333 continues to apply a downward force along the axis of the main shaft 1 to the stabilizing plate 432. Therefore, after the rotating shaft 41 rotates 90 degrees, the stabilizing plate 432 can prevent the rotating shaft 41 from continuing to rotate in time, so that the filter plate can accurately stay at each work station with the corresponding posture.

[0056] A mashing method for a wine-producing mashing device, applied to a wine-producing mashing device, comprises the following steps:

[0057] S1, after the crushing mechanism crushes the grapes, the pulp and juice fall into the separation mechanism;

[0058] S2. Inside the separation mechanism, the pulp and juice fall along the separation pipe 5 onto the filter 3. The pulp remains on the filter 3, while the juice continues to flow downward.

[0059] S3. When the filter 3 is loaded with a large amount of pulp (the pulp affects filtration), the main shaft 1 rotates, and the main shaft 1 drives the filter 3 to rotate synchronously around the axis of the main shaft 1 through the flip connection structure 4. At the same time, when the filter 3 rotates to the first cleaning station, the flip connection structure 4 flips the filter 3 90 degrees and performs preliminary cleaning at the first cleaning station;

[0060] S4, the main shaft 1 continues to rotate, and the filter 3 rotates to the second cleaning station. At this time, the flip connection structure 4 flips the filter 3 again by 90 degrees and performs a second cleaning at the second cleaning station;

[0061] S5, the main shaft 1 rotates again, the filter screen 3 rotates to the sterilization station, the filter screen 3 is sterilized, and finally the filter screen 3 rotates back to the separation station.
