Description

Technical Field

[0001] This invention relates to the field of strength testing technology, and in particular to a quality testing device for the production of goat milk Fuzhuan tea. Background Technology

[0002] Black tea, a type of post-fermented tea, is famous for containing *Aspergillus cristatus* (golden flower). The production of Fu brick tea requires more than 20 processes, including pile fermentation, pressing, and the formation of the golden flower. The formation of the golden flower is the core of its quality, giving the tea soup a mellow taste and functions such as regulating metabolism.

[0003] Goat milk Fu brick tea is made by adding goat milk during the pile fermentation process. This adds the milky aroma and nutrition of goat milk while maintaining the original taste of Fu brick tea. It is an improved version of Fu brick tea.

[0004] In the quality inspection of Fu brick tea, a density test is required before the fermentation process. If the density is too low, moisture loss will be faster during the fermentation process. If the density is too high, reliable air circulation cannot be guaranteed, which will affect the quality of the fermentation.

[0005] In traditional techniques, the density of Fu brick tea is tested by subjective evaluation through manual squeezing. This method has low accuracy and is affected by subjectivity. It cannot guarantee that the density of the tea brick meets the requirements, and the uniformity of the mold growth is also poor, resulting in inconsistent quality of the final product.

[0006] Therefore, this invention proposes a quality testing device for the production of goat milk Fuzhuan tea. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quality testing device for the production of goat milk Fuzhuan tea.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A quality inspection device for producing goat milk Fuzhuan tea includes a base and a support platform fixed to the ground. A vertical rod is fixed to the top outer wall of the base. A rotating rod is rotatably connected longitudinally to the top of the vertical rod. A rotating rod is rotatably connected laterally to one side of the rotating rod. The ends of the rotating rods, located above the support platform, are respectively connected via pneumatic telescopic devices to grippers for picking up and putting down materials and pressure plates for cooperating with the support platform to detect compaction. A pressure sensor for sensing the applied pressure is installed at the connection between the pressure plate and the pneumatic telescopic device, and a displacement sensor for detecting displacement is installed inside the pneumatic telescopic device.

[0009] Preferably, its quality inspection includes the following steps: S1: First, through experiments, determine the empirical function L=f(F) between the pressure F on the tea brick under the qualified density P and the deformation L of the tea brick under the pressure F. S2: Then, the tea bricks are sampled from the conveyor of the tea brick production line to the top of the support platform by the pneumatic telescopic device, the gripper picks up and puts in, and the rotation of the first rotating rod. Then the second rotating rod rotates to rotate the pressure plate to the bottom. S3: The pneumatic telescopic device connecting the pressure plate extends, so that the pressure plate contacts the top of the tea brick and applies pressure. During this process, the pressure sensor and the displacement sensor respectively detect the pressure of the pressure plate on the tea brick and detect the deformation of the tea brick under pressure by detecting the displacement of the pressure plate. S4: The actual amount received by the tea brick is F 实际 The pressure is input as the independent variable into the empirical function to obtain the theoretical deformation variable L that meets the density requirements. 理论 Then L 理论 L detected by the displacement sensor 实际 Perform a comparison and set an error coefficient α; S5: If (1-α)L 理论 ≤L 实际 ≤(1+α)L 理论 If the density of the tea brick meets the requirements, then the density of the tea brick is determined to be sufficient; otherwise, it does not.

[0010] Furthermore: the inner wall of the pole is fixed with a motor by bolts, the outer wall of the motor's output shaft is fixed with a sleeve, and the inner side wall of the sleeve is connected to the main shaft by a transmission protrusion with clearance fit.

[0011] Based on the aforementioned scheme: a second bevel gear is fixed to the top outer wall of the main shaft, and a first bevel gear that mates with the second bevel gear is fixed to the outer wall of the rotating rod. The outer wall of the main shaft is fixed with a transmission pawl, and the bottom inner wall of the rotating rod is provided with a ratchet groove that engages with the transmission pawl. At the same time, the inner wall of the rotating rod at the top of the ratchet groove is provided with a smooth groove for accommodating the transmission pawl.

[0012] A better embodiment of the aforementioned scheme is that an electromagnet is fixed to the inner wall of the cavity of the upright pole by a bracket, and a permanent magnet that cooperates with the electromagnet is fixed to the outer wall of the main shaft located above the electromagnet.

[0013] As a further aspect of the present invention: the outer wall of the main shaft is rotatably connected to a movable disk via a bearing, the outer wall of the movable disk is longitudinally slidably connected to the inner wall of the upright through a gap fit between a key-shaped protrusion and a key-shaped groove, and the top outer wall of the movable disk is connected to a pressure plate via multiple arc-shaped steel plates, the upper surface of the pressure plate being engaged with the lower end face of the rotating rod.

[0014] Meanwhile, the top outer wall of the main shaft is rotatably connected to a sliding frame that is slidably connected to the inner wall of the rotating rod, and the top lower surface of the sliding frame is fixed with a bevel gear three that mates with bevel gear one.

[0015] As a preferred embodiment of the present invention: the outer wall of the rotating rod 2 is provided with a high-pressure gas tank and a gas supply mechanism for supplying gas to the high-pressure gas tank, and the high-pressure gas tank is connected to the rodless chamber and the rod chamber of the pneumatic telescopic device through a two-position four-way valve.

[0016] Meanwhile, the air supply mechanism includes a fixing ring fixed to one side wall of the rotating rod and an air supply cylinder fixed to the two side walls of the rotating rod. The inner wall of the air supply cylinder is slidably connected to a compressor piston. The outer wall of the compressor piston is connected to a ball bearing via a connecting rod. The ball bearing is slidably connected to the side of the fixing ring. The side of the fixing ring is provided with multiple arc-shaped protrusions. The inner wall of the air supply cylinder is fixed with a spring. The other end of the spring is fixed to the inner end face of the compressor piston.

[0017] As a preferred embodiment of the present invention: one side of the air supply cylinder is fixed and connected to a three-way pipe, and the other two ports of the three-way pipe are respectively connected to the air inlet of the high-pressure gas tank and the atmospheric environment through a one-way valve. The one-way valve connecting to the atmospheric environment is directed from the atmospheric environment to the inner cavity of the air supply cylinder, and the one-way valve connecting to the high-pressure gas tank is directed from the inner cavity of the air supply cylinder to the air inlet of the high-pressure gas tank.

[0018] The beneficial effects of this invention are as follows: 1. This invention establishes a reasonable and accurate tea brick density testing system by using the pressure and deformation of the tea brick as the correlation dimensions of tea brick density, then determining the empirical formula through experiments, and finally judging whether the density of the tea brick is qualified by comparing the actual test value with the theoretical value, thereby solving the various defects of traditional manual testing.

[0019] 2. This invention uses an electric motor as a single power source input, the axial movement of the main shaft as a "clutch", and the cooperation of an electromagnet and a permanent magnet as a "clutch driver" for the main shaft. This achieves comprehensive driving of rotation of rod one and rotation of rod two, while ensuring that the drive source that needs to be connected to electricity is in a fixed state and will not cause problems such as wire harness entanglement and breakage due to its movement.

[0020] 3. By setting up components such as pressure plates and bevel gears, this invention can lock non-driving components, such as rotating rod one or rotating rod two, on the basis of comprehensive drive, thereby preventing them from moving and increasing the reliability of the device. At the same time, the locking and unlocking of rotating rod one and rotating rod two are entirely achieved by the movement of the main shaft, thereby reducing the required drive source arrangement and increasing the synchronous linkage of the device.

[0021] 4. This invention, based on the integrated drive of rotating rod one and rotating rod two to ensure that the power source is in a fixed state and to prevent wire entanglement, provides power to the pneumatic telescopic device and gripper by setting a high-pressure air tank, and provides air pressure to the high-pressure air tank through an air supply mechanism. The power of the high-pressure air tank comes from the rotation of rotating rod two itself, thereby further integrating the drive required for the entire process, ensuring that there are no components on the moving parts that need to be connected to electricity, and further preventing the risk of wire entanglement and breakage.

[0024] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0025] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] Example 1: A quality testing device for goat milk Fuzhuan tea production, such as... Figures 1-8 As shown, the device includes a base 1 and a support platform 10 fixed to the ground. A vertical rod 2 is fixed to the top outer wall of the base 1. A rotating rod 3 is rotatably connected to the top of the vertical rod 2. A rotating rod 5 is rotatably connected to one side of the rotating rod 3. The ends of the rotating rod 5, located above the support platform 10, are respectively connected to grippers 9 for picking up and putting down materials and pressure plates 7 for cooperating with the support platform 10 to detect compaction through pneumatic expansion joints 8. A pressure sensor for sensing the applied pressure is provided at the connection between the pressure plate 7 and the pneumatic expansion joint 8, and a displacement sensor for detecting displacement is provided inside the pneumatic expansion joint 8.

[0027] Quality inspection includes the following steps: S1: First, through experiments, determine the empirical function L=f(F) between the pressure F of the tea brick under the qualified density P and the deformation L of the tea brick under the pressure F. That is, through multiple screenings, verify the tea bricks that meet the density requirements for subsequent fermentation. Then, apply pressure to the tea bricks and detect their deformation. Multiple data obtained through multiple experiments can be used to obtain the relationship between the pressure and deformation of the tea bricks that meet the fermentation requirements through linear interpolation and curve fitting. S2: Then, the tea bricks are sampled from the conveyor of the tea brick production line to the top of the support platform 10 by the extension and retraction of the pneumatic telescopic device 8, the pick-up and drop of the gripper 9, and the rotation of the rotating rod 1 3. Then, the rotating rod 2 5 rotates to rotate the pressure plate 7 to the bottom. S3: The pneumatic telescopic device 8 connected to the pressure plate 7 extends, so that the pressure plate 7 contacts the top of the tea brick and applies pressure. During this process, the pressure sensor and the displacement sensor respectively detect the pressure of the pressure plate 7 on the tea brick and detect the deformation of the tea brick under pressure by detecting the displacement of the pressure plate 7. S4: The actual amount received by the tea brick is F 实际 The pressure is input as the independent variable into the empirical function to obtain the theoretical deformation variable L that meets the density requirements. 理论 Then L 理论 L detected by the displacement sensor 实际 Perform a comparison and set an error coefficient α; S5: If (1-α)L 理论 ≤L 实际 ≤(1+α)L 理论 If the density of the tea brick meets the requirements, then the density of the tea brick is determined to be sufficient; otherwise, it does not.

[0028] This device uses the pressure and deformation of the tea brick as the correlation dimension of the tea brick density, then determines the empirical formula through experiments, and finally judges whether the density of the tea brick is qualified by comparing the actual test value with the theoretical value. In this way, a reasonable and accurate tea brick density detection system is established, which solves the various defects of traditional manual detection.

[0029] Example 2: A quality testing device for goat milk Fuzhuan tea production, such as... Figures 1-8 As shown, in order to solve the driving problem, this embodiment makes the following improvements based on embodiment 1: the inner wall of the pole 2 is fixed with a motor 19 by bolts, the outer wall of the output shaft of the motor 19 is fixed with a sleeve 20, and the inner side wall of the sleeve 20 is connected to the main shaft 21 by a transmission protrusion 24 in a clearance fit.

[0030] A bevel gear 23 is fixed to the top outer wall of the main shaft 21, and a bevel gear 22 that mates with the bevel gear 23 is fixed to the outer wall of the rotating rod 25.

[0031] A transmission pawl 26 is fixed to the outer wall of the main shaft 21. A ratchet groove 27 is provided on the bottom inner wall of the rotating rod 3 to engage with the transmission pawl 26. At the same time, a slot 25 for accommodating the transmission pawl 26 is provided on the inner wall of the rotating rod 3 at the top of the ratchet groove 27.

[0032] An electromagnet 29 is fixed to the inner wall of the cavity of the upright 2 by a bracket, and a permanent magnet 28 that cooperates with the electromagnet 29 is fixed to the outer wall of the main shaft 21 located above the electromagnet 29.

[0033] When the motor 19 starts, it drives the sleeve 20 to rotate, which in turn drives the main shaft 21 to rotate through the transmission action of the transmission protrusion 24. When it is necessary to drive the rotating rod 3 to rotate, the direction of the current flowing through the electromagnet 29 is controlled so that the electromagnet 29 generates an attractive force on the permanent magnet 28. The permanent magnet 28 is driven by the attractive force to move the main shaft 21 downward, so that the transmission pawl 26 and the ratchet groove 27 engage. However, at this time, the bevel gear 1 22 and the bevel gear 23 do not mesh. The rotation of the main shaft 21 can drive the rotating rod 3. When it is necessary to drive the rotating rod 25 to rotate, the direction of the current flowing through the electromagnet 29 is changed, so that the direction of its magnetic field is changed. The electromagnet 29 generates a repulsive force on the permanent magnet 28, thereby using the repulsive force to drive the permanent magnet 28 and the main shaft 21 to move upward. At this time, the ratchet 27 disengages from the transmission pawl 26, and the transmission pawl 26 is located in the slot 25. Meanwhile, the bevel gear 23 engages with the bevel gear 22. At this time, the rotation of the main shaft 21 can drive the rotating rod 25 to rotate through the meshing of the bevel gear 23 and the bevel gear 22.

[0034] This device uses an electric motor 19 as a single power source input, the axial movement of the main shaft 21 as a "clutch", and the cooperation between the electromagnet 29 and the permanent magnet 28 as a "clutch driver" for the main shaft 21. This achieves comprehensive driving of the rotation of the first rotating rod 3 and the second rotating rod 5, while ensuring that the drive source that needs to be connected to electricity is in a fixed state and will not cause problems such as wire harness entanglement and breakage due to its movement.

[0035] The outer wall of the main shaft 21 is rotatably connected to the movable disk 32 via the bearing 33. The outer wall of the movable disk 32 is longitudinally slidably connected to the inner wall of the upright rod 2 via the gap fit between the key-shaped protrusion 34 and the key-shaped groove 35. The top outer wall of the movable disk 32 is connected to the pressure plate 30 via multiple arc-shaped steel plates 31. The upper surface of the pressure plate 30 is engaged with the lower end face of the rotating rod 3.

[0036] The top outer wall of the main shaft 21 is rotatably connected to a sliding frame 36 that is slidably connected to the inner wall of the rotating rod 3. The top lower surface of the sliding frame 36 is fixed with a bevel gear 37 that cooperates with the bevel gear 22.

[0037] When the main shaft 21 is in the position where the drive rod 3 rotates, both the main shaft 21 and the moving disk 32 are in the lower position. The rod 3 does not contact the pressure plate 30. At the same time, the bevel gear 22 and the bevel gear 37 cooperate to lock the rod 5. When the main shaft 21 is in the position where the drive rod 5 rotates, the main shaft 21 moves upward, thereby driving the pressure plate 30 to move upward through the moving disk 32. The pressure plate 30 contacts the end face of the rod 3 and is pressed by the deformation of the arc-shaped steel plate 31, locking the rod 3. At the same time, the bevel gear 22 and the bevel gear 37 disengage.

[0038] This device, by setting up components such as pressure plate 30 and bevel gear 37, can lock non-driving components such as rotating rod 1 3 or rotating rod 2 5 on the basis of comprehensive drive, thereby preventing them from following the movement and increasing the reliability of the device. At the same time, the locking and unlocking of rotating rod 1 3 and rotating rod 2 5 are entirely achieved by the movement of the main shaft 21, thereby reducing the required drive source arrangement and increasing the synchronous linkage of the device.

[0039] Example 3: A quality testing device for goat milk Fuzhuan tea production, such as... Figures 1-8 As shown, in order to solve the driving problem, this embodiment makes the following improvements based on embodiment 2: A high-pressure gas tank 6 and a gas supply mechanism 4 for supplying gas to the high-pressure gas tank 6 are provided on the outer wall of the rotating rod 2 5. The high-pressure gas tank 6 is connected to the rodless chamber and the rod chamber of the pneumatic telescopic device 8 through a two-position four-way valve. Its driving logic is as follows: When the pneumatic expansion joint 8 needs to extend, the position of the two-position four-way valve changes, connecting the high-pressure air tank 6 to the rodless chamber of the pneumatic expansion joint 8, and connecting the rod chamber of the pneumatic expansion joint 8 to the atmospheric environment. At this time, the high-pressure gas in the high-pressure air tank 6 enters the rodless chamber of the pneumatic expansion joint 8, and the pneumatic expansion joint 8 extends under pressure. When the pneumatic expansion joint 8 needs to retract, the air path is switched, connecting the high-pressure air tank 6 to the rod chamber of the pneumatic expansion joint 8, and connecting the rodless chamber of the pneumatic expansion joint 8 to the atmosphere. Of course, for speed control and position holding of the pneumatic expansion joint 8, valve components such as opening valves and pressure valves need to be installed between the high-pressure air tank 6 and the two-position four-way valve. Since this is existing technology, it is widely used in hydraulic control and pneumatic control. This embodiment only designs the high-pressure air tank 6, the pressure power source of the pneumatic expansion joint 8, based on the pneumatic expansion joint 8. Those skilled in the art can refer to existing technology to add functionality to the other parts, which will not be elaborated in this embodiment.

[0040] Meanwhile, the gripper 9 can also be pneumatically driven. The gripper 9 only needs linear displacement to complete the picking and putting of materials. It can also be driven and controlled by the high-pressure air tank 6 driving the pneumatic telescopic device 8.

[0041] The air supply mechanism 4 includes a fixing ring 11 fixed to the side wall of the rotating rod 3 and an air supply cylinder 38 fixed to the side wall of the rotating rod 5. A compressor piston 15 is slidably connected to the inner wall of the air supply cylinder 38. A ball bearing 13 is connected to the outer wall of the compressor piston 15 via a connecting rod 14. The ball bearing 13 is rotatably connected to the side of the fixing ring 11. The side of the fixing ring 11 is provided with multiple arc-shaped protrusions 12. A spring 16 is fixed to the inner wall of the air supply cylinder 38. The other end of 6 is fixed to the inner end face of the air compressor piston 15, and is fixed to one side of the air supply cylinder 38 and connected to a three-way pipe 17. The other two ports of the three-way pipe 17 are respectively connected to the air inlet of the high-pressure air tank 6 and the atmospheric environment through a one-way valve 18. The one-way valve 18 connected to the atmospheric environment has a passage direction from the atmospheric environment to the inner cavity of the air supply cylinder 38, and the one-way valve 18 connected to the high-pressure air tank 6 has a passage direction from the inner cavity of the air supply cylinder 38 to the air inlet of the high-pressure air tank 6.

[0042] When the rotating rod 5 rotates, it drives the air supply cylinder 38 to rotate, thereby causing the ball bearing 13 to roll along the side of the fixed ring 11. When the ball bearing 13 rolls to the arc protrusion 12, it is limited by the arc protrusion 12, which causes the air compressor piston 15 to move inward, squeezing the gas in the inner cavity of the air supply cylinder 38 into the high-pressure gas tank 6 through the one-way valve 18, providing air pressure to the high-pressure gas tank 6. When the ball bearing 13 rolls away from the arc protrusion 12, the air compressor piston 15 rebounds under the elastic force of the spring 16, and the inner cavity of the air supply cylinder 38 draws in gas from the atmospheric environment through the one-way valve 18, and so on.

[0043] This device, based on the integrated drive of rotating rod 3 and rotating rod 5 to ensure that the power source is in a fixed state and to prevent wire entanglement, provides power to the pneumatic telescopic device 8 and gripper 9 by setting up a high-pressure air tank 6, and provides air pressure to the high-pressure air tank 6 through the air supply mechanism 4. The power of the high-pressure air tank 6 comes from the rotation of rotating rod 5 itself, thereby further integrating the drive required for the entire process, ensuring that there are no components on the moving parts that need to be connected to electricity, and further preventing the risk of wire entanglement and breakage.

[0044] However, for the entire air circuit, the valves involved only need to control the workstation, and their power requirements are negligible compared to the power required by the drive source. This can be solved by placing a small battery on the rotating rod 25.

[0045] In this embodiment, when the rotating rod 5 rotates, it drives the air supply cylinder 38 to rotate, thereby causing the ball bearing 13 to roll along the side of the fixed ring 11. When the ball bearing 13 rolls to the arc-shaped protrusion 12, it is limited by the arc-shaped protrusion 12, causing the compressor piston 15 to move inward. This compresses the gas in the inner cavity of the air supply cylinder 38 through the one-way valve 18 into the high-pressure gas tank 6, providing air pressure to the high-pressure gas tank 6. When the ball bearing 13 rolls away from the arc-shaped protrusion 12, the compressor piston 15 rebounds under the elastic force of the spring 16, and the inner cavity of the air supply cylinder 38 draws in gas from the atmospheric environment through the one-way valve 18. This process is repeated until gas is needed. When the pneumatic expansion joint 8 extends, the position of the two-position four-way valve changes, connecting the high-pressure air tank 6 with the rodless chamber of the pneumatic expansion joint 8, and connecting the rod chamber of the pneumatic expansion joint 8 with the atmospheric environment. At this time, the high-pressure gas in the high-pressure air tank 6 enters the rodless chamber of the pneumatic expansion joint 8, and the pneumatic expansion joint 8 extends under pressure. When the pneumatic expansion joint 8 needs to retract, the air path is switched, connecting the high-pressure air tank 6 with the rod chamber of the pneumatic expansion joint 8, and connecting the rodless chamber of the pneumatic expansion joint 8 with the atmosphere. Of course, for speed control and position holding of the pneumatic expansion joint 8, valve components such as opening valves and pressure valves also need to be installed between the high-pressure air tank 6 and the two-position four-way valve.

[0046] 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.
