[0025] The present invention provides a production detection device and method for a coffee machine filter. Compared with the prior art, it has the following beneficial effects:

[0026] 1. The production detection device of the coffee machine filter adopts an upper detection cylinder and a lower detection cylinder to cooperate with the coffee machine filter to be detected, and uses sand mixed with water to simulate coffee bean particles for testing. If sand passes through the coffee machine filter, it means that the mesh density of the coffee machine filter is unqualified. On the basis of gravity detection, the present invention further adds a two-stage dynamic detection method of one stirring and one shaking. By moving the sand to increase the difficulty, the quality of the coffee machine filter can be better detected. The experiment is simple, convenient and low-cost. Compared with the simple and direct penetration experiment, the detection accuracy is better, which ensures the quality of the produced coffee machine filter.

[0027] 2. The production inspection device for the coffee machine filter sets a transparent observation bottle at the bottom of the lower inspection cylinder. If sand passes through the coffee machine filter during the inspection, it means that part or all of the pores of the coffee machine filter are too large, thus indicating that its quality is unqualified. After inspecting a coffee machine filter, when the inspection mechanism is turned over and the coffee machine filter is opened to be replaced, the sand in the transparent observation bottle will slide to the outside of the sand collecting hopper due to the layout of the sand retaining hopper and the sand collecting hopper during the turning process. When turning back again, the sand on the outside of the sand collecting hopper will slide to the outside of the sand retaining hopper, thereby preventing the sand from falling onto the coffee machine filter to be replaced and causing the sand to be scattered. The sand retaining hopper only needs to be pushed up, and the sand on the outside can be discharged from the bottom for easy collection and reuse. The structural layout is ingenious and the use is flexible and convenient.

[0028] 3. The production and testing device for the coffee machine filter has a stirring structure that can be driven by wind to rotate during the testing process, thereby churning up sand. The dynamic sand can pass through and pass through the coffee machine filter more comprehensively than the static sand, thereby more effectively testing the quality of the coffee machine filter. At the same time, the stirring structure can also be equipped with an eccentric swinging structure. While rotating and churning the sand, it can also drive the testing mechanism itself to move to achieve a shaking effect. Under the dual dynamic effects, the quality of the coffee machine filter can be further tested, and the eccentric swinging structure can be used selectively, thereby providing multiple levels of experimental effects for the quality inspection of the coffee machine filter, and the structure is simple and convenient to operate.

[0029] 4. The production and detection device for the coffee machine filter has a simple bracket structure. The diameter of the lower ring is larger than that of the upper ring. The structure with a small upper part and a large lower part is relatively stable. The detection mechanism can be placed in both directions by using a spring and a U-shaped seat to position the support rod. It can be used for both the replacement and detection steps of the coffee machine filter. The elastic support method allows the detection mechanism to further increase the vibration amplitude when it swings, so as to better detect the quality of the coffee machine filter.

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] The present invention discloses a production detection device for a coffee machine filter and provides the following four technical solutions:

[0052] Figure 1-Figure 4 The first embodiment is shown: it includes a detection mechanism for placing a coffee machine filter 1 for detection, and a bracket 2 for placing and supporting the detection mechanism, and the detection mechanism includes:

[0053] The upper detection cylinder 3 is filled with water and sand simulating coffee bean particles. The diameter of the sand is larger than the aperture of the standard coffee machine filter 1. A stirring structure 31 is also provided inside the upper detection cylinder 3. The stirring structure 31 stirs the sand to increase the probability of passing through the coffee machine filter 1. A driving member is installed on the top of the upper detection cylinder 3 to drive the stirring structure 31 to rotate. An eccentric swinging structure 32 is installed on the top of the stirring structure 31 to make the detection mechanism shake as a whole by using centrifugal force when rotating. The eccentric swinging structure 32 can be driven or not driven by the stirring structure 31. A heating structure can also be installed in the upper detection cylinder 3 to further simulate the influence of temperature on the coffee machine filter 1, or to increase the influence of other physical factors.

[0054] The lower detection cylinder 4 cooperates with the upper detection cylinder 3 to clamp the coffee machine filter 1 therebetween, and the lower detection cylinder 4 is used to receive and observe the water and sand that leak through the coffee machine filter 1;

[0055] A sealing gasket 7 is also provided on the bottom surface of the upper detection cylinder 3, and a groove for positioning the coffee machine filter 1 is provided on the bottom surface of the sealing gasket 7;

[0056] The clamp 5 is used to dock and fix the upper detection tube 3 and the lower detection tube 4, and the clamp 5 is mounted on the bracket 2 for use, and the bracket 2 elastically supports the clamp 5 to increase the swing amplitude of the detection mechanism;

[0057] A pneumatic power source 6 is mounted on the bracket 2 for driving the driving member in a split manner to avoid the influence of the shaking of the detection mechanism on the pneumatic power source 6 .

[0058] The present invention adopts an upper detection cylinder 3 and a lower detection cylinder 4 to cooperate with a coffee machine filter 1 to be tested, and uses sand mixed with water to simulate coffee bean particles for testing. If sand passes through the coffee machine filter 1, it means that the mesh density of the coffee machine filter 1 is unqualified. On the basis of gravity detection, the present invention also adds a two-stage dynamic detection method of one stirring and one shaking. By making the sand move to increase the difficulty, the quality of the coffee machine filter 1 can be better detected. The experiment is simple, convenient and low-cost. Compared with a simple and direct penetration experiment, the detection accuracy is better, thereby ensuring the quality of the produced coffee machine filter 1.

[0059] Figure 5-Figure 8A second embodiment is shown, which is mainly different from the first embodiment in that: a transparent observation bottle 41 is threadedly connected to the bottom of the lower detection tube 4, and a sand collecting bucket 42 is installed inside the lower detection tube 4. The sand collecting bucket 42 is used to gather the fallen sand particles to the middle and discharge them into the transparent observation bottle 41. A sand blocking bucket 43 covering the outside of the bottom end of the sand collecting bucket 42 is also provided at the bottom of the inner cavity of the lower detection tube 4. The sand blocking bucket 43 is used to isolate the sand particles from the periphery when the detection mechanism is turned over to prevent the sand particles from entering the sand collecting bucket 42; the structure of the sand blocking bucket 43 is similar to a teacup with a teacup holder at the bottom, and a plurality of connecting rods 45 are fixedly connected to the bottom of the sand blocking bucket 43, which slide through the bottom of the lower detection tube 4 and are connected by a push ring 46. The bottom of the sand blocking bucket 43 is separated from or attached to the inner wall of the lower detection tube 4 by pushing and pulling the push ring 46. The bottom of the lower detection tube 4 is conical, so that when the sand blocking bucket 43 rises and separates from the lower detection tube 4, the sand particles on the periphery of the sand blocking bucket 43 slide toward the center and are discharged;

[0060] A plurality of through holes 47 are evenly arranged on the top of the sand collecting hopper 42, and a fine filter 44 covering the through holes 47 is pasted on the outer wall of the sand collecting hopper 42, and the mesh size of the fine filter 44 is smaller than the mesh size of the coffee machine filter 1. When the detection mechanism is flipped, the water outside the sand collecting hopper 42 flows back into the upper detection cylinder 3 through the through holes 47, and the water discharged back into the upper detection cylinder 3 can also flush some of the sand remaining on the coffee machine filter 1 back into the upper detection cylinder 3.

[0061] By arranging a transparent observation bottle 41 at the bottom of the lower detection cylinder 4, if sand passes through the coffee machine filter 1 during the detection process, it means that part or all of the pores of the coffee machine filter 1 are too large, thereby indicating that its quality is unqualified. After testing a coffee machine filter 1, when the detection mechanism is turned over and the coffee machine filter 1 is opened to replace, the sand in the transparent observation bottle 41 will slide to the outside of the sand collecting hopper 42 due to the layout of the sand retaining hopper 43 and the sand collecting hopper 42 during the turning process, and the sand on the outside of the sand collecting hopper 42 will slide to the outside of the sand retaining hopper 43 when turning back again, thereby preventing sand from falling onto the coffee machine filter 1 to be replaced and causing the sand to be scattered. The sand retaining hopper 43 only needs to be pushed up, and the sand on the outside can be discharged from the bottom for easy collection and reuse. The structural layout is ingenious and the use is flexible and convenient.

[0062] Figure 9-11 The third embodiment is shown, which is mainly different from the first embodiment in that the stirring structure 31 includes a stirring rod 311 and a stirring blade 312 fixed at its bottom end, and the stirring blade 312 is a blade type, which causes the sand to tumble when rotating;

[0063] The driving member includes a wind hood 33 fixedly connected to the top of the upper detection cylinder 3 by nuts and studs, a prism sleeve 34 is fixedly sleeved on the surface of the stirring rod 311 and located at the top of the upper detection cylinder 3, and the prism sleeve 34 passes through the top of the wind hood 33, and a fan blade 35 axially sleeved outside the prism sleeve 34 rotates in the wind hood 33, an air inlet nozzle 331 is tangentially connected to one side of the wind hood 33, and an air outlet 332 is tangentially opened on the other side of the wind hood 33, and the air outlet 332 and the air inlet nozzle 331 are opposite in direction but located on both sides of the axis, so that the air flow flows in an annular direction, and the fan blade 35 is driven to rotate by blowing air from the air inlet nozzle 331 into the wind hood 33;

[0064] The eccentric swing structure 32 includes a swing rod 321, one end of which is provided with a prism hole adapted to the prism sleeve 34, a magnetic ring 322 is bonded inside the swing rod 321 and at the top of the prism hole, the magnetic force of the magnetic ring 322 prevents the swing rod 321 from sliding down and connecting with the prism sleeve 34, and the stirring rod 311 is a round shaft with a smooth surface, so the friction is small when rotating, and the eccentric swing structure 32 will not be driven to rotate, or the eccentric swing structure 32 will only rotate very slowly, the prism hole is covered with the prism sleeve 34 by pressing down the swing rod 321, and the other end of the swing rod 321 is threadedly connected with a counterweight block 323.

[0065] During the detection process, the stirring structure 31 can be driven by wind to rotate by the driving part, so that the sand can be churned up. The dynamic sand can pass through the coffee machine filter 1 more comprehensively than the static sand, so the quality of the coffee machine filter 1 can be detected more effectively. At the same time, the stirring structure 31 can also be equipped with an eccentric swinging structure 32. While rotating and churning the sand, it can also drive the detection mechanism itself to move to achieve a shaking effect. Under the dual dynamic effects, the quality of the coffee machine filter 1 can be further detected, and the eccentric swinging structure 32 can be used selectively, thereby providing multiple levels of experimental effects for the quality inspection of the coffee machine filter 1, and the structure is simple and convenient to operate.

[0066] Figure 1 Figure 2 and Figure 12-13 The fourth embodiment is shown, which is mainly different from the first embodiment in that: the hoop 5 comprises a left half hoop 51 and a right half hoop 52 which are hinged to each other at one end, the other end of the right half hoop 52 is rotatably connected with a T-shaped stud 53, and one end of the T-shaped stud 53 is threadedly connected with a butterfly nut 54, the other end of the left half hoop 51 is provided with a hanging block, and a notch adapted to the T-shaped stud 53 is opened inside the hanging block, and the T-shaped stud 53 is inserted into the notch and the butterfly nut 54 is tightened to fasten the upper detection tube 3 and the lower detection tube 4;

[0067] The upper detection tube 3 and the lower detection tube 4 have convex edges extending outward from the opposite surfaces. The outer surface of the convex edge is an inclined surface, and a wear-resistant metal ring 301 is embedded and fixed on the inclined surface. When the clamp 5 is tightened, the wear-resistant metal ring 301 is squeezed to compress the upper detection tube 3 and the lower detection tube 4.

[0068] The clamp 5 is used to fix the upper detection tube 3 and the lower detection tube 4. It only needs to tighten a butterfly nut 54 to fix them, and there is no need to tighten them throughout the process or completely disassemble them. The fastening is simple and convenient. At the same time, the design of the wear-resistant metal ring 301 can also avoid the wear of the upper detection tube 3 and the lower detection tube 4 caused by frequent fastening.

[0069] The bracket 2 includes an upper ring 21 and a lower ring 22, and a plurality of vertical plates 23 are connected between the upper ring 21 and the lower ring 22. The pneumatic power source 6 includes an air pump 61 fixedly connected to the vertical plate 23 on one side through a mounting plate 24. An air filling pipe 62 is connected between the air outlet end of the air pump 61 and the air inlet nozzle 331. A dust filter cover is provided at the air inlet end of the air pump 61. A starting switch 63 is fixedly connected between the vertical plates 23 on the other side through the mounting plate 24. The starting switch 63 is connected to an external power supply and is connected to the air pump 61 through a wire.

[0070] The top of the upper ring 21 is elastically connected to multiple U-shaped seats 26 through multiple evenly distributed springs 25, and the sides of the clamp 5 and the upper detection tube 3 are fixedly connected to multiple clamping rods 55. The detection mechanism is placed on the bracket 2 by placing the clamping rods 55 into the U-shaped seats 26.

[0071] By setting the bracket 2 with a simple structure, the diameter of the lower ring 22 is larger than the diameter of the upper ring 21, and the structure with a small upper part and a large lower part is relatively stable. The spring 25 cooperates with the U-shaped seat 26 to position the support clamping rod 55, so that the detection mechanism can be placed forward and backward, which can be used for the replacement step of the coffee machine filter 1 and the detection step of the coffee machine filter 1. The elastic support method allows the detection mechanism to further increase the shaking amplitude when swinging, so as to better detect the quality of the coffee machine filter 1.

[0072] The present invention also discloses a detection method based on a production detection device for a coffee machine filter, comprising the following steps:

[0073] Step 1: First, turn the detection mechanism upside down, and use the clamping rod 55 to invert the upper detection cylinder 3 on the U-shaped seat 26 of the bracket 2, and screw the butterfly nut 54 of the clamping hoop 5 to the end of the T-shaped stud 53, and then turn the T-shaped stud 53 to open the left half hoop 51 and the right half hoop 52, and then remove the lower detection cylinder 4, pour water and sand into the upper detection cylinder 3, and then put the coffee machine filter 1 to be tested, and then cover the lower detection cylinder 4 on the upper detection cylinder 3 to press the coffee machine filter 1, and then use the clamping hoop 5 to lock the upper detection cylinder 3 and the lower detection cylinder 4, and then turn it over and put it on the bracket 2, so that the clamping rod 55 of the clamping hoop 5 is locked in;

[0074] Step 2: First, observe whether there are sand grains in the transparent observation bottle 41 in a static state to preliminarily judge the quality of the coffee machine filter 1; if no sand grains are observed, start the air pump 61 to blow air into the wind cover 33 through the inflation tube 62, so as to make the fan blade 35 rotate and drive the stirring structure 31 to rotate through the prism sleeve 34 to perform a second detection on the stirring of the sand grains, and observe again whether there are sand grains falling into the transparent observation bottle 41 in a dynamic state; if no sand grains are observed, press down the eccentric swing structure 32, use the stirring structure 31 to drive the eccentric swing structure 32 to rotate so as to shake the detection mechanism to perform a third detection, and observe again whether there are sand grains falling into the transparent observation bottle 41;

[0075] Step 3: Determine the quality of the coffee machine filter 1 through triple testing and record it, then repeat step 1 to replace the coffee machine filter 1;

[0076] Step 4: Regularly remove the transparent observation bottle 41, push up the push ring 46 to lift up the sand retaining bucket 43, and the sand on the periphery slides toward the middle along the inclined surface of the bottom of the lower detection tube 4 and is discharged from the bottom of the lower detection tube 4. After all the sand is discharged, pull down the push ring 46 to make the bottom of the sand retaining bucket 43 fit the bottom of the inner wall of the lower detection tube 4, and then the inspection can be carried out urgently.
