A solid-liquid separation equipment for distiller's grains in liquor processing

Abstract

This invention belongs to the field of alcohol production by-product recovery technology, specifically a solid-liquid separation device for baijiu (Chinese liquor) processing. It includes an outer cylinder, a pressurizing component, a traction component, and a filtering component. The pressurizing component is located inside the outer cylinder, the traction components are symmetrically arranged on the left and right sides of the pressurizing component, and the filtering component is located at the bottom of the pressurizing component. This device can separate the solid and liquid components of the baijiu mixture fed into it. Because the baijiu is separated by a concave filter screen, frequent replacement and cleaning are required during continuous processing, which is inconvenient. Therefore, after each batch of baijiu is filtered, the bottom cover can be reversed by turning it upside down to apply reverse pressure, discharging the solid baijiu accumulated in the mesh of the concave filter screen and clearing the blockage. This significantly improves the filtration performance of the device without requiring frequent replacement and cleaning.

Description

Technical Field

[0001] This invention belongs to the field of alcohol production by-product recycling technology, specifically a solid-liquid separation device for baijiu (Chinese liquor) processing. Background Technology

[0002] During the brewing process of baijiu, the agricultural by-products after solid-state fermentation and still distillation to extract the original liquor, namely the lees, still contain about 10% residual liquor and a variety of aroma and flavor substances. These residues are valuable by-products in the brewing process. However, due to the special nature of the brewing process, the lees still need to be recycled after the brewing is completed.

[0003] An existing baijiu (Chinese liquor) production lees separation device with publication number CN223351229U separates the liquor and lees through centrifugal filtration. However, the separated lees remain inside the second and first filter screens, causing the mesh to be easily clogged and the filtration effect to drop significantly. During continuous processing, frequent replacement and cleaning are required, which is inconvenient to use. Therefore, improvements are needed. Summary of the Invention

[0004] To address the problem of mesh clogging easily by lees during filtration in existing technologies, the present invention provides a solid-liquid separation device for baijiu (Chinese liquor) processing, comprising an outer cylinder, a pressurizing component, a traction component, and a filtering component. The pressurizing component is disposed inside the outer cylinder, the traction components are symmetrically arranged on the left and right sides of the pressurizing component, and the filtering component is disposed at the bottom of the pressurizing component. The pressurizing component includes a docking slide, a torque motor, a threaded pressurizing rod, a compression connecting rod, and a sliding inner cover. A threaded groove is provided at the center of the inner cavity of the docking slide cylinder. The outer surface of the threaded pressure rod is threadedly connected to the center of the inner cavity of the docking slide cylinder through the threaded groove. The outer surface of the sliding inner cover is slidably connected to the inner wall of the docking slide cylinder, and the center of the inner cavity of the sliding inner cover is rotatably connected to the bottom end of the threaded pressure rod. The filter component includes a flip-down bottom cover, a concave filter screen, and a side-deflection motor; The concave filter screen is engaged with the middle of the inner wall of the flip-top cover, and the outer surface of the flip-top cover is inserted into the bottom end of the docking slide cylinder. Both the upper and lower sides of the flip-top cover can be connected to the bottom insertion part of the docking slide cylinder to form a cylinder structure. The inner wall of the side deflection motor is rotatably connected to a built-in rotating core. A fixing bracket is inserted into the outer surface of the built-in rotating core. The end of the fixing bracket away from the side deflection motor is inserted into the outer surface of the flip-top cover. The outer surface of the side deflection motor housing is inserted into the inner wall of the outer cylinder. The docking slide is docked with the flip-top cover at the bottom through a traction component to form a container. The torque motor rotates the threaded pressure rod clockwise, pushing the sliding inner cover down to pressurize the lees inside the container. The wine permeates through the concave filter screen, while the solid lees remain inside the flip-top cover. After filtration, the docking slide slides up and separates from the flip-top cover. The side deflection motor twists the flip-top cover, and the lees are filtered again through the other side of the concave filter screen.

[0005] Furthermore, the pressurizing component also includes: The feeding guide tube has its outer surface fitted with the inner wall of the threaded pressure rod. The bottom end of the feeding guide tube extends to the outside of the sliding inner cover, and the top end of the feeding guide tube extends to the outside of the outer cylinder. The external lees mixture is transported through the feeding guide tube to the cylinder composed of the docking slide and the flip-top cover. During the pressurization of the lees, the operator will seal the top end of the feeding guide tube. The upper part of the outer surface of the docking slide is slidably connected to the inner wall of the outer cylinder. The bottom end of the torque motor shaft is inserted into the top end of the threaded pressure rod. The top of the torque motor housing is inserted into the top end of the compression connecting rod through a connecting plate. The top end of the compression connecting rod is snapped into the top of the torque motor housing through a connecting plate. A fixed guide cylinder is slidably connected to the bottom end of the compression connecting rod. The bottom end of the fixed guide cylinder is inserted into the upper surface of the docking slide.

[0006] Furthermore, the traction component includes: Side guide plates are symmetrically arranged on the left and right sides of the inner wall of the outer cylinder; The guide slide plate has one side of its outer surface slidably connected to the inner cavity of the side guide plate via a slide groove, and the other side of its outer surface is inserted into the outer surface of the docking slide cylinder via a docking slot. The pneumatic pull rod machine has its outer surface engaged with the upper part of the outer surface of the side guide plate. Guide slide rods are evenly inserted into the inner cavity of the pneumatic pull rod machine. The bottom end of each guide slide rod is inserted into the top of the inner cavity of the guide slide plate. The guide slide rod is a fixed hollow rod. By applying pressure to the lower part of the guide slide rod, the pneumatic pull rod machine can push the guide slide plate, which is inserted at the bottom of the guide slide rod, downwards, thereby causing the docking slide cylinder to slide down and tightly engage with the lower flip-top cover. The pneumatic pull rod machine can also drive the guide slide plate to slide upwards within a certain range by applying pressure.

[0007] Furthermore, the outer cylinder includes: The control panel is located on the front of the outer surface of the outer cylinder. Adjustment knobs are evenly distributed on the lower part of the outer surface of the control panel.

[0008] Furthermore, it also includes: A buffer top piece is installed at the top of the inner wall of the outer cylinder to limit the sliding of the docking slide. The transfer component, located at the bottom of the inner wall of the outer cylinder, is used to transfer the filtered wine. The lower sealing sleeve is located on the front and rear sides of the lower part of the inner wall of the outer cylinder; The lees container is used to collect the filtered solid lees.

[0009] Furthermore, the transfer component includes: The container has symmetrical drainage openings on both sides of its inner cavity, and extended outer shells are symmetrically inserted into both sides of the inner cavity through the drainage openings. The container has a disc-shaped structure with an inner convex and outer concave shape. The wine dripped into the inner wall of the container will be drained into the extended outer shells on both sides of the bottom. The liquid-drawing tube has one end inserted into the inner cavity of the extended outer shell and the other end extending to the outside of the outer cylinder. The liquid-drawing tube is a hollow rigid tube structure.

[0010] Furthermore, the transfer component also includes: The deflecting rotating cylinder has its outer surface inserted into the bottom of the inner cavity of the outer cylinder, and the inner cavity of the deflecting rotating cylinder is evenly provided with inner transfer wheels through a motor. A liquid pump is located at the axis of the inner wall of the deflecting drum. The outer surface of the liquid pump is rotatably connected to the axis of the inner wall of the deflecting drum via an inner adapter wheel. The inner cavity of the liquid pump is inserted into the inner cavity of the liquid pump. The liquid pump draws the liquid from the holding tray to the outside of the device through the liquid pump through the liquid pump, and also draws the liquid from the holding tray and the inside of the extended outer shell through the liquid pump through the liquid pump.

[0011] Furthermore, the lower sealing sleeve includes: The docking cover has its top surface fitted with the outer surface of the flip-top cover, and its bottom surface fitted with the top surface of the outer surface of the holding chassis. The bottom of the docking cover can be engaged with the top of the holding chassis, and the top of the docking cover can be engaged with the end of the flip-top cover. At this time, the flip-top cover, the docking cover, and the holding chassis form the lower cylindrical structure. A control push plate is provided, the outer surface of which is engaged with the inner wall of the outer cylinder, and the inner cavity of which is inserted into the outer surface of the docking cover via a spring slide rod.

[0012] Furthermore, the lees holding component includes: A supporting base frame, the top of which is inserted into the bottom of the outer cylinder; The sliding inner plate has its top slidably connected to the axis of the inner wall of the support base, and a spring cover is sleeved on the bottom of the outer surface of the sliding inner plate. The weighing machine is installed on the upper part of the inner wall of the support base, and the top of the spring cover is inserted into the bottom of the weighing machine's inner cavity.

[0013] Furthermore, the buffer top member includes: The upper chuck, the outer surface of which engages with the upper part of the inner wall of the outer cylinder; An external pressure sensor is installed on the upper surface of the upper chuck. Sensing heads are evenly inserted into the bottom of the inner cavity of the external pressure sensor, and the sensing heads extend to the outside of the upper chuck through a through-hole. A compression spring is inserted into the inner wall of the sensing head, and the bottom end of the compression spring is inserted into the upper surface of the docking slide.

[0014] The beneficial effects of this invention are as follows: 1. This device can perform solid-liquid separation on the mixture of lees fed into it. Because the lees are separated by a concave filter screen, a lot of solid lees will remain on the screen, which will easily clog the mesh and significantly reduce the filtration effect. During continuous processing, frequent replacement and cleaning are required, which is inconvenient. Therefore, after each batch of lees is filtered, the bottom cover can be flipped upside down to apply reverse pressure, which will drain the solid lees accumulated in the mesh of the concave filter screen and clear the blockage. This significantly improves the filtration performance of the device without the need for frequent replacement and cleaning.

[0015] 2. Directly stamping the inverted bottom cover can easily cause the lees on the outer surface of the concave filter screen to diffuse downwards, resulting in the lees being dispersed inside the outer cylinder. This not only makes it difficult to recover the lees but also requires subsequent cleaning of the inner wall of the outer cylinder to prevent bacterial growth. Therefore, a sliding docking cover is installed between the inverted bottom cover and the holding tray. Without affecting the inversion of the bottom cover and the holding tray, the inverted bottom cover, docking cover, and holding tray form a temporary cylinder structure to guide the lees downwards, ensuring that the lees can smoothly enter the holding tray and avoid contaminating the inner wall of the outer cylinder.

[0016] 3. The cascading base guides the liquid to flow to the extended outer shell on both sides through the raised structure on the inner wall, thus avoiding the problem of liquid accumulating inside the cascading base. After the cascading base is rotated 180°, more solid waste can be collected through its concave surface. Then, during subsequent rotations, the solid waste is placed into the sliding inner plate below. Therefore, the solid waste is discharged in a segmented manner. This not only ensures that the solid waste is accurately transferred to the sliding inner plate, but also ensures that the solid-liquid separated solid waste will not be remixed using the same transfer component in subsequent processes, which would lead to a deterioration in the separation effect.

[0017] 4. Since the sliding inner cover separates the liquid and solid matter inside the lees through pressurization, the connection between the docking slide and the flip-top cover needs to be relatively tight. At this time, the pneumatic pull rod machine continuously pressurizes the bottom guide slide through the guide rod. The downward pressure of the guide slide drives the docking slide to slide down, so that the docking slide and the bottom flip-top cover are tightly inserted to prevent air pressure from leaking out from the non-concave filter screen. At this time, the docking slide slides down rapidly under its own gravity and the pressurization of the pneumatic pull rod machine. However, the top of the docking slide is connected to a compression spring, so the impact force on the inner wall partition of the outer cylinder is small when the docking slide is pressed down to the lowest point, thus protecting the internal structure of the outer cylinder.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0021] Example 1, please refer to Figures 1-4 This invention provides a technical solution: a solid-liquid separation device for baijiu (Chinese liquor) processing, comprising an outer cylinder 1, a pressurizing component 2, a traction component 4, and a filtering component 5. The pressurizing component 2 is disposed inside the outer cylinder 1, the traction component 4 is symmetrically disposed on the left and right sides of the pressurizing component 2, and the filtering component 5 is disposed at the bottom of the pressurizing component 2. The pressurizing component 2 includes a docking slide 21, a torque motor 23, a threaded pressurizing rod 26, a compression connecting rod 24, and a sliding inner cover 27. A threaded groove is provided at the center of the inner cavity of the docking slide cylinder 21. The outer surface of the threaded pressure rod 26 is threadedly connected to the center of the inner cavity of the docking slide cylinder 21 through the threaded groove. The outer surface of the sliding inner cover 27 is slidably connected to the inner wall of the docking slide cylinder 21, and the center of the inner cavity of the sliding inner cover 27 is rotatably connected to the bottom end of the threaded pressure rod 26. The filter component 5 includes a flip-down bottom cover 51, a concave filter screen 52, and a side deflection motor 53; The concave filter screen 52 is engaged with the middle of the inner wall of the flip-top cover 51, the outer surface of the flip-top cover 51 is inserted into the bottom end of the docking slide cylinder 21, and both the upper and lower sides of the flip-top cover 51 can be connected to the bottom insertion part of the docking slide cylinder 21 to form a cylinder structure. The inner wall of the side deflection motor 53 is rotatably connected to the built-in rotating core 54. The outer surface of the built-in rotating core 54 is inserted with a fixing bracket 55. The end of the fixing bracket 55 away from the side deflection motor 53 is inserted with the outer surface of the flip-top cover 51. The outer surface of the outer shell of the side deflection motor 53 is inserted with the inner wall of the outer cylinder 1. The docking slide 21 is docked with the flip-top cover 51 at the bottom through the traction component 4 to form a container. The torque motor 23 rotates the threaded pressure rod 26 clockwise to push the sliding inner cover 27 down to pressurize the lees inside the container. The wine permeates through the concave filter screen 52, and the lees solids are retained inside the flip-top cover 51. After filtration, the docking slide 21 slides up and separates from the flip-top cover 51. The side deflection motor 53 twists the flip-top cover 51, and the lees are filtered again through the other side of the concave filter screen 52.

[0022] The pressurizing component 2 also includes: The feed guide pipe 28 has its outer surface fitted with the inner wall of the threaded pressure rod 26. The bottom end of the feed guide pipe 28 extends to the outside of the sliding inner cover 27, and the top end of the feed guide pipe 28 extends to the outside of the outer cylinder 1. The external lees mixture is transported through the feed guide pipe 28 to the cylinder composed of the docking slide 21 and the flip bottom cover 51. During the pressurization of the lees, the operator will seal the top end of the feed guide pipe 28. The upper part of the outer surface of the docking slide 21 is slidably connected to the inner wall of the outer cylinder 1. The bottom end of the shaft of the torque motor 23 is inserted into the top end of the threaded pressure rod 26. The top of the housing of the torque motor 23 is inserted into the top end of the compression connecting rod 24 through a connecting plate. The top end of the compression connecting rod 24 is snapped into the top of the housing of the torque motor 23 through a connecting plate. The bottom end of the compression connecting rod 24 is slidably connected to a fixed guide cylinder 25. The bottom end of the fixed guide cylinder 25 is inserted into the upper surface of the docking slide 21.

[0023] Traction component 4 includes: Side guide plates 41 are symmetrically arranged on the left and right sides of the inner wall of the outer cylinder 1. The guide slide plate 42 has one side of its outer surface slidably connected to the inner cavity of the side guide plate 41 via a slide groove, and the other side of its outer surface is inserted into the outer surface of the docking slide cylinder 21 via a docking slot 22. The pneumatic tie rod 44 has its outer surface engaged with the upper part of the outer surface of the side guide plate 41. Guide slide rods 43 are evenly inserted into the inner cavity of the pneumatic tie rod 44. The bottom end of the guide slide rod 43 is inserted into the top of the inner cavity of the guide slide plate 42. The guide slide rod 43 is a fixed hollow rod. By applying pressure to the lower part of the guide slide rod 43, the pneumatic tie rod 44 can push the guide slide plate 42, which is inserted at the bottom of the guide slide rod 43, downward, thereby driving the docking slide cylinder 21 to slide down and tightly engage with the lower flip-top cover 51. The pneumatic tie rod 44 can also drive the guide slide plate 42 to slide upward within a certain range by drawing pressure.

[0024] The outer cylinder 1 includes: Control panel 11 is located at the front of the outer surface of outer cylinder 1; Adjustment knobs 12 are evenly distributed on the lower part of the outer surface of control panel 11.

[0025] Before using the device, start the traction component 4 by adjusting the knob 12. Drive the guide slide plate 42 to slide down and drive the docking slide 21 down. At this time, the bottom of the docking slide 21 is inserted into the top of the horizontally set flip-top cover 51 below. Then, add the lees mixture to the inner cylinder through the top feeding guide pipe 28. After completing the preparation work, seal the top of the feeding guide pipe 28.

[0026] Torque motor 23 rotates the threaded pressure rod 26 clockwise, and the threaded pressure rod 26 pushes the sliding inner cover 27 to slide down continuously. Torque motor 23 also slides down under the guidance of the compression connecting rods 24 on both sides. At this time, the pressure in the space where the lees are located gradually increases, and the wine will be separated from the lees solids through the concave filter screen 52 of the bottom flip cover 51, thus realizing solid-liquid separation.

[0027] After pressurization, the solid lees will remain on the upper part of the concave filter screen 52. At this time, the traction component 4 pulls the docking slide 21 upward. After the docking slide 21 separates from the flip bottom cover 51, the torque motor 23 lifts the sliding inner cover 27 back to its original position by rotating the threaded pressure rod 26 counterclockwise. The flip bottom cover 51 also flips 180° under the torsion of the front and rear side deflection motors 53, so that the flip bottom cover 51 and the inner concave filter screen 52 are upside down. Then, the docking slide 21 is docked with the flip bottom cover 51 again, and pressurization is performed again. At this time, the solid lees on the lower surface of the concave filter screen 52 will fall off under its own weight and the pressure from above, and then completely separate from the concave filter screen 52, realizing the transfer of solid lees. After the concave filter screen 52 is effectively cleared, the docking slide 21 is separated from the flip bottom cover 51. The flip bottom cover 51 flips 180° again to return to its initial state, and then the subsequent solid-liquid separation of lees is carried out.

[0028] During the separation of the liquid inside the lees, the transfer component 6 is in... Figure 6 In the state shown, the end of the holding base 61 is facing upwards. The control push plate 71 on the side pushes the docking cover 73 through the spring slide rod 72, so that the bottom of the flip cover 51, the docking cover 73 and the holding base 61 together form the lower cylindrical structure. The wine dripping down from the concave filter screen 52 will enter the interior of the holding base 61, and then be drawn out by the liquid pumps 64 on both sides through the liquid pumping pipe 63 for collection.

[0029] Example 2, please refer to Figures 1-9 The present invention provides a technical solution: based on embodiment 1, it further includes: The buffer top part 3 is set at the top of the inner wall of the outer cylinder 1 to limit the sliding of the docking slide cylinder 21; The transfer component 6 is located at the bottom of the inner wall of the outer cylinder 1 and is used to transfer the filtered wine. The lower sealing sleeve 7 is located on the front and rear sides of the lower part of the inner wall of the outer cylinder 1; Distillery lees container 8 is used to collect the filtered solid lees.

[0030] Transfer component 6 includes: The base plate 61 has symmetrical drainage openings on both sides of its inner cavity, and an extended outer shell 62 is symmetrically inserted into both sides of the inner cavity of the base plate 61 through the drainage openings. The base plate 61 has a disc-shaped structure with an inner convex and outer concave shape. The wine dripped into the inner wall of the base plate 61 will be guided to the extended outer shell 62 on both sides of the bottom. The liquid extraction tube 63 has one end inserted into the inner cavity of the extended outer shell 62, and the other end extends to the outside of the outer cylinder 1. The liquid extraction tube 63 is a hollow rigid tube structure.

[0031] Transfer component 6 also includes: The biasing rotating drum 66 has its outer surface inserted into the bottom of the inner cavity of the outer cylinder 1, and the inner cavity of the biasing rotating drum 66 is evenly provided with inner transfer wheels 65 through the motor. A liquid pump 64 is located at the axis of the inner wall of the deflecting rotating cylinder 66. The outer surface of the liquid pump 64 is rotatably connected to the axis of the inner wall of the deflecting rotating cylinder 66 via an inner adapter wheel 65. The inner cavity of the liquid pump pipe 63 is inserted into the inner cavity of the liquid pump 64. The liquid pump 64 draws the liquid from the holding tray 61 to the outside of the device through the liquid pump pipe 63. The liquid pump 64 also draws the liquid from the holding tray 61 and the inside of the extended outer shell 62 through the liquid pump pipe 63.

[0032] The lower sealing cylinder 7 includes: The docking cover 73 is fitted with the outer surface of the top of the outer surface of the docking cover 73 and the outer surface of the flip-top cover 51. The bottom of the outer surface of the docking cover 73 is fitted with the top of the outer surface of the holding chassis 61. The bottom of the docking cover 73 can be engaged with the top of the holding chassis 61. The top of the docking cover 73 can be engaged with the end of the flip-top cover 51. At this time, the flip-top cover 51, the docking cover 73 and the holding chassis 61 form the lower cylindrical structure. The control push plate 71 is engaged with the inner wall of the outer cylinder 1 on its outer surface, and the inner cavity of the control push plate 71 is inserted into the outer surface of the docking cover 73 through the spring slide rod 72.

[0033] The lees container component 8 includes: Support base 81, the top of support base 81 is inserted into the bottom of outer cylinder 1; The top of the sliding inner plate 82 is slidably connected to the axis of the inner wall of the support base 81, and a spring cover 83 is sleeved on the bottom of the outer surface of the sliding inner plate 82. The weighing machine 84 is located on the upper part of the inner wall of the support base 81, and the top of the spring cover 83 is inserted into the bottom of the inner cavity of the weighing machine 84.

[0034] The top buffer 3 includes: Upper chuck 32, the outer surface of upper chuck 32 is engaged with the upper part of the inner wall of outer cylinder 1; An external pressure sensor 31 is installed on the upper surface of the upper chuck 32. Sensing heads 33 are evenly inserted into the bottom of the inner cavity of the external pressure sensor 31, and the sensing heads 33 extend to the outside of the upper chuck 32 through the through-hole. A compression spring 34 is inserted into the inner wall of the sensing head 33, and the bottom end of the compression spring 34 is inserted into the upper surface of the docking slide cylinder 21.

[0035] While the upper filter component 5 is pressurizing the solid lees, the lower deflecting drum 66 also inverts the holding tray 61 by twisting the liquid pump 64 180°. At this time, the holding tray 61 uses its concave surface to hold the solid lees that fall from above. When collecting the wine later, the holding tray 61 will flip back to its original position, and the lees will be placed into the lower sliding inner tray 82 by the holding tray 61. The collection of solid lees is completed inside the sliding inner tray 82.

[0036] Solid lees accumulate inside the sliding inner plate 82. As the amount of lees increases, the sliding inner plate 82 slides down relative to the supporting base 81 under the weight of the lees. The outer spring cover 83 applies a gradually increasing pulling force to the weighing machine 84 above. When the collected lees reach a certain weight, the solid lees need to be transferred. At this time, the outer cylinder 1 is separated from the supporting base 81, the solid lees inside the sliding inner plate 82 are poured out, and then the outer cylinder 1 and the supporting base 81 are plugged in and combined.

[0037] Since the sliding inner cover 27 separates the wine and solid matter inside the lees by applying pressure, the connection between the docking slide 21 and the flip-top cover 51 needs to be relatively tight. At this time, the pneumatic pull rod 44 continuously applies pressure to the bottom guide slide 42 through the guide slide rod 43. The downward force of the guide slide 42 drives the docking slide 21 to slide down, so that the docking slide 21 and the bottom flip-top cover 51 are tightly inserted to prevent air pressure from leaking out from the non-concave filter screen 52. At this time, the docking slide 21 slides down rapidly under its own gravity acceleration and the pressure of the pneumatic pull rod 44. However, the top of the docking slide 21 is connected to the compression spring 34, so the impact force on the inner wall partition of the outer cylinder 1 is small when the docking slide 21 is pressed down to the lowest point, thereby protecting the internal structure of the outer cylinder 1.

[0038] When the docking slide 21 is lifted upward, the distance between the docking slide 21 and the flip bottom cover 51 is sufficient to allow the flip bottom cover 51 to deflect. When the docking slide 21 moves upward, it will squeeze the sensing end 33 through the compression spring 34, thereby feeding back the upward sliding distance of the docking slide 21 based on the squeezing force of the sensing end 33 on the external pressure sensor 31, while preventing the docking slide 21 from hitting the upper chuck 32.

[0039] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
