Description

Technical Field

[0001] The invention relates to the technical field of hardness detection, and in particular to a digital tenderness detector. Background Art

[0002] Tripe hotpot is a traditional specialty of Chongqing, belonging to Sichuan or Chongqing cuisine. The stove of Chongqing tripe hotpot is under the table. There is a big hole in the middle of the table, and a big pot is placed on it. The inside is divided into several grids, one for each person. Diners who don't know each other can share the pot and eat. The ingredients of tripe hotpot are diverse, the taste is fresh and spicy, and the soup is rich. Diners can simmer and eat by themselves. It has a unique flavor and is deeply loved by people. Its main ingredients are tripe, beef liver, beef kidney, etc.

[0003] In order to adapt to market demand, hot pot base manufacturers, while producing hot pot base, also produce bagged tripe to make it convenient for consumers to purchase tripe, so that consumers can conveniently make tripe hot pot at home. The processing and production of tripe generally includes material selection, fat layer peeling, cleaning, blanching and shaping, reagent treatment, rinsing, soaking, impurity removal, knife changing, bagging and other processes. Among them, the tripe that has been processed and bagged needs to be subjected to quality sampling. The inspection content mainly includes manual visual inspection of the tripe matching uniformity, whether there is thin skin, whether there is peculiar smell, and experimental inspection of the tenderness of the tripe. The tenderness of the tripe is the most important technical indicator for evaluating the edible physical properties of tripe products, and it truly reflects the physical structure characteristics of the tripe. At present, there is no fixed inspection standard for the tenderness of the tripe. The general detection method is to rely on manual experience judgment or use a hardness tester to test the hardness of the tripe, and then deduce the tenderness of the tripe based on the measured hardness value. Since the hardness tester is large in size and is generally placed in the laboratory, the tripe needs to be sent to the laboratory when testing the tenderness of the tripe, which wastes time and has low detection efficiency. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a digital tenderness detector, which solves the problem of inconvenience in detecting the tenderness of tripe in the prior art.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a digital tenderness detector, including a support plate, a pushing mechanism and a push pin connected to the pushing mechanism are provided on the support plate, and the tenderness detector is provided between the push pin and the pushing mechanism; a baffle is fixedly connected to the support plate, a socket is provided on the baffle and is opposite to the push pin, and a pressing mechanism is provided on the pushing mechanism and is opposite to the baffle.

[0006] The principle of the present invention is: the tenderness and crispness of tripe are different depending on the shear force it can withstand when cutting. The shear force refers to the force used by the thimble of the testing instrument to pierce the tested tripe sample. We use the magnitude of this shear force to characterize the tenderness of the tripe, by recording the force used when the thimble pierces the tripe sample and taking the measured shear force peak value (maximum force) as the tripe tenderness value.

[0007] When it is necessary to detect the tripe, the tripe is directly placed between the baffle and the thimble, and then the pushing mechanism is pushed to make the pushing mechanism push the thimble to move toward the tripe, and the thimble gradually approaches the tripe. Since the baffle has a supporting effect on the tripe, the tripe will not shift after the thimble contacts the tripe, so that the thimble pierces the tripe. In the process of the thimble piercing the tripe, the thimble will be subject to resistance from the tripe, and the thimble transmits the resistance from the tripe to the tenderness detector. The tenderness detector records the maximum resistance encountered by the thimble, and the maximum resistance value encountered by the thimble in the process of piercing the tripe is equal to the peak shear force when the thimble pierces the tripe. The tenderness of the tripe can be clearly judged by the maximum resistance value recorded on the tenderness detector; at the same time, when the pushing mechanism pushes the thimble to move toward the tripe, the pressing mechanism moves toward the tripe with the thimble, thereby fixing the tripe on the baffle to prevent the tripe from shifting when the thimble pierces the tripe and affecting the process of the thimble piercing the tripe. The detection accuracy is higher after the pressing mechanism is set.

[0008] The advantages of adopting the above solution are:

[0009] 1. Ability to quickly detect the tenderness of tripe: Compared with the prior art that uses a hardness tester to test the hardness of tripe, the hardness tester is large in size, has many control procedures, and is cumbersome to operate, so the detection efficiency is not high. In this application, a special tenderness tester is set up. When testing the tenderness of tripe, it is only necessary to place the tripe between the baffle and the ejector pin, and then use the push mechanism to push the ejector pin to pierce the tripe. The tenderness of the tripe can be quickly detected using the special tenderness tester, and the detection is convenient and efficient. At the same time, since the tenderness tester in this application is fixed on the support plate, and the ejector pin and the push mechanism are much simpler in structure than the hardness tester, when using the tenderness tester of this application for detection, the tenderness tester can be taken to the detection site, so that the tenderness detection of the tripe can be completed at the same time as the manual visual inspection, thereby improving the efficiency of the entire detection.

[0010] 2. The detection results are more accurate: In the present application, while the pushing mechanism is used to push the ejector pin to pierce the tripe, the pressing mechanism is also simultaneously pushed to press the tripe, thereby preventing the tripe from shifting under the force of the ejector pin when the ejector pin pierces the tripe, thereby making the detection results more accurate.

[0011] 3. The test results are intuitive and easy to read: In this application, a special tenderness detector is used to detect the tenderness of the tripe, and the tenderness detector will only record the maximum resistance encountered by the thimble when piercing the tripe. When the thimble is used to pierce the tripe, the maximum resistance is encountered at the moment the thimble pierces the tripe, and the force used by the thimble to pierce the tripe is directly related to the tenderness of the tripe. Therefore, the tenderness of the tripe can be detected by only recording the force when the thimble pierces the tripe. At the same time, the test results are retained on the tenderness detector, which is convenient for the tester to view and record.

[0012] Furthermore, the pushing mechanism includes a smooth-stroke quick clamp, and the tenderness detector includes a detection display unit and a fixed rod and a force-bearing rod connected to the detection display unit. The fixed rod is fixedly connected to the sliding rod of the quick clamp, and the force-bearing rod is fixedly connected to the ejector pin.

[0013] The quick clamp is used to push the thimble to move smoothly and directionally, thereby ensuring that the thimble stably pierces the tripe. The detection display unit is used to detect the force applied to the thimble and display the maximum resistance applied to the thimble. The fixing rod is fixedly connected to the slider of the quick clamp, so that when the quick clamp is pushed manually, the slider of the quick clamp can quickly push the tenderness detector to realize the detection. The force-bearing rod is used to transmit the resistance applied to the thimble to the detection display unit.

[0014] Furthermore, a support is fixedly connected to the support plate, a guide hole is opened on the support, and the force-bearing rod is slidably connected in the guide hole.

[0015] Compared with only using a quick clamp to push the ejector pin and the tenderness detector to move, the ejector pin is less supported and is prone to shaking during the piercing process and is not easy to align with the socket. In this solution, preferably, a support is provided on the support plate, and a guide hole for the load-bearing rod to slide is provided on the support. The guide hole provides guidance and support for the sliding of the load-bearing rod, so that the ejector pin piercing the tripe is more stable and accurate.

[0016] Furthermore, a guide sleeve is fixedly connected in the guide hole.

[0017] A guide sleeve is fixedly connected in the guide hole to reduce the friction between the force-bearing rod and the guide hole, so that the detection result of the detection display unit is more accurate.

[0018] Furthermore, a connecting sleeve coaxially arranged with the guide sleeve is provided between the ejector pin and the stress-bearing rod, one end of the connecting sleeve is fixedly connected to the ejector pin, and the other end is threadedly connected to the stress-bearing rod.

[0019] Since one end of the connecting sleeve is fixedly connected to the ejector pin and the other end is threadedly connected to the force-bearing rod, the distance between the ejector pin and the force-bearing rod can be adjusted by adjusting the depth of the force-bearing rod being screwed into the connecting sleeve, and finally the distance between the ejector pin and the baffle can be adjusted, thereby facilitating the adjustment of the distance between the ejector pin and the baffle to an appropriate size, so that the tripe can be conveniently placed between the ejector pin and the baffle.

[0020] Furthermore, the support is provided with a notch arranged along the axial direction of the guide hole, the notch is communicated with the guide hole, and the support is provided with a fixing hole arranged along the radial direction of the guide hole and passing through the notch.

[0021] Compared with using screws to fix the guide strip, or directly using a linear bearing with a flange to replace the guide sleeve, it is necessary to open a corresponding threaded hole on the support to fix the linear bearing, making the entire structure more complicated. In this solution, since the notch is connected to the guide hole, and the fixing hole opened on the support passes through the notch, the size of the notch can be reduced by locking a screw in the fixing hole, thereby reducing the size of the guide hole and fixing the guide sleeve in the guide hole. Since the guide sleeve can be fixed with only one screw, adjustment and disassembly are very convenient, the structure is simple, and it is easy to operate.

[0022] Furthermore, the pressing mechanism includes a slide plate fixedly connected to the slide rod, a pressure plate fixedly connected to the slide plate, a pressure block slidably connected to the pressure plate and arranged opposite to the baffle, an elastic member fixedly connected between the pressure plate and the pressure block, and a side of the pressure block close to the baffle is at a distance from the baffle that is smaller than the distance between the ejector pin and the baffle.

[0023] When the quick clamp is pushed, the slide bar drives the slide plate to move, and the slide plate drives the pressure plate and the pressure block to move. Since the distance between the side of the pressure block close to the baffle plate and the baffle plate is smaller than the distance between the ejector pin and the baffle plate, the pressure block reaches the baffle plate earlier than the ejector pin, so that the pressure block fixes the tripe before the ejector pin pierces the tripe. The slide bar is fixed on the slide bar, and an elastic part is fixedly connected between the pressure block and the pressure plate, so that the pressure block pressing against the tripe will not affect the tenderness detection of the tripe by the tenderness detector. The elastic part is provided to ensure that the pressure block can continue to push the ejector pin toward the tripe after fixing the tripe, so that the ejector pin can smoothly pierce the tripe.

[0024] Furthermore, a slide rail is fixedly connected to the support plate, and the slide plate is fixedly connected to a slider of the slide rail.

[0025] The slide rails are set to facilitate the smooth and precise sliding of the skateboard.

[0026] Furthermore, the insertion hole passes through the baffle, a cleaning needle coaxially arranged with the ejector pin is fixedly connected to the slide plate, and the baffle is located between the cleaning needle and the ejector pin.

[0027] When the ejector pin pierces the tripe, the punctured tripe pieces may be pushed into the socket, thus affecting the accuracy of subsequent tripe detection. In this solution, a cleaning pin is fixedly connected to the slide board. When the ejector pin is pushed toward the tripe, the ejector pin pierces the tripe to detect the tenderness of the tripe. After the detection, the ejector pin is pushed in the opposite direction to move it away from the socket. At the same time, the slide board drives the cleaning pin to be inserted into the socket, so that the cleaning pin clears the socket and prevents the tripe from being blocked in the socket and affecting subsequent detection.

[0028] Furthermore, a receiving frame is fixedly connected to the support plate, and the receiving frame is located below the insertion hole.

[0029] Since the tripe may be broken when the thimble pierces it, in order to prevent the tripe from falling onto the support plate at will, in this solution, a receiving frame is fixed under the insertion hole, and the falling tripe is collected by the receiving frame.

[0037] Embodiment 1 is basically as follows Figure 1 As shown, the digital tenderness detector comprises a laterally arranged support plate 1, on which a pushing mechanism, a tenderness detector, a push pin 2 and a baffle 3 are arranged in sequence from right to left, the pushing mechanism comprises a quick clamp 4 fixedly connected to the support plate 1 by screws, the slide bar 5 on the quick clamp 4 is laterally arranged horizontally, and the free end of the slide bar 5 is arranged to the left; the tenderness detector comprises a detection display unit 6, a fixed rod 7 and a force rod 8, wherein the principle of the detection display unit 6 is similar to that of a spring dynamometer, when the detection display unit 6 is subjected to an external force, the magnitude of the force applied will be displayed, the left end of the fixed rod 7 is welded to the detection display unit 6, the right end of the fixed rod 7 is fixedly connected to the left end of the slide bar 5 by screws, and the right end of the force rod 8 is welded to the sensing component of the detection display unit 6, so that when the force rod 8 is subjected to an external force, the force can be transmitted to the detection display unit 6, so that the detection display unit 6 can detect the force applied to the force rod 8 and display the magnitude of the force applied.

[0038] Combination Figure 1 and Figure 2 As shown, the left end of the force-bearing rod 8 is provided with an external thread, and a connecting sleeve 9 is threadedly connected to the external thread of the force-bearing rod 8. The left end of the connecting sleeve 9 is welded to the ejector pin 2. By adjusting the depth of the force-bearing rod 8 threaded into the connecting sleeve 9, the position of the ejector pin 2 relative to the support plate 1 can be adjusted. In order to effectively support the connecting sleeve 9, a support 10 is fixedly connected to the support plate 1 by screws, and a transversely arranged guide hole is provided on the support 10. The connecting sleeve 9 is located in the guide hole. In order to reduce the friction force on the connecting sleeve 9 when sliding transversely and reduce the influence of the friction force on the detection accuracy of the tenderness detector, in this embodiment, a guide sleeve 11 is fixedly connected to the guide hole by screws.

[0039] like Figure 2 As shown, in order to facilitate the removal of the guide sleeve 11 and the adjustment of the position of the guide sleeve 11, a transversely arranged slot 12 is provided at the top of the support 10, and the slot 12 extends downward to be connected with the guide hole, and a fixing hole in the front-to-back direction is provided on the support 10, and the fixing hole passes through the front side to the rear side of the support 10, and the fixing hole passes through the slot 12, and a screw can be locked in the fixing hole. Due to the presence of the slot 12, the size of the guide hole can be changed. When the screw is locked in the fixing hole, the size of the guide hole is reduced, so that the guide sleeve 11 in the guide hole is fixed.

[0040] Combination Figure 1 and Figure 2 The baffle plate 3 is located on the left side of the thimble 2 and a gap for placing the tripe is provided between the thimble 2 and the baffle plate 3. The baffle plate 3 is fixedly connected to the support plate 1 by screws. A socket 13 opposite to the thimble 2 is provided on the baffle plate 3. When the thimble 2 is pushed to the left, the thimble 2 can pierce the tripe between the thimble 2 and the baffle plate 3, and then be inserted into the socket 13. In order to prevent the debris generated when the thimble 2 pierces the tripe from falling onto the support plate 1 at will, in this embodiment, a receiving frame 14 is fixedly connected to the support plate 1 by screws. The receiving frame 14 is located below the socket 13 so as to receive the tripe debris falling from the socket 13.

[0041] The specific implementation process is as follows:

[0042] When the tenderness of the tripe needs to be tested, first place the tripe in the gap between the ejector pin 2 and the baffle plate 3, and then manually push the quick clamp 4 to make the slide bar 5 of the quick clamp 4 slide to the left, and the slide bar 5 pushes the fixed rod 7, the detection display unit 6, and the force-bearing rod 8 to move to the left together, and the force-bearing rod 8 pushes the connecting sleeve 9 to slide to the left in the guide sleeve 11, and the connecting sleeve 9 pushes the ejector pin 2 to move to the left and gradually approaches the tripe.

[0043] When the thimble 2 comes into contact with the tripe, the tripe cannot be displaced due to the supporting effect of the baffle 3, and as the thimble 2 continues to be pushed to the left, the thimble 2 will gradually apply force to the tripe until the thimble 2 pierces the tripe. When the thimble 2 pierces the tripe, the thimble 2 will be subjected to a reverse force from the tripe, and the thimble 2 transmits the reverse force to the detection and display unit 6 through the connecting sleeve 9 and the force-bearing rod 8 in sequence. The detection and display unit 6 detects the force applied to the thimble 2 and records the maximum pressure applied to the thimble 2 during the process of the thimble 2 piercing the tripe. The tester can know the maximum pressure applied to the thimble 2 based on the recorded value of the detection and display unit 6, and it can be known from the process of the thimble 2 piercing the tripe that the pressure applied to the thimble 2 is the greatest at the moment the tripe is pierced. Therefore, the tenderness of the tripe can be directly judged based on the maximum pressure recorded by the detection and display unit 6.

[0044] After the tripe is pierced, the ejector pin 2 is inserted into the jack 13. At this time, the quick clamp 4 is pulled in the opposite direction, and the ejector pin 2 returns to the initial position. After recording the recorded data on the detection display unit 6, the detection display unit 6 is manually adjusted to reset it to the initial state. Then the position of the tripe corresponding to the jack 13 is changed, and the above operation is repeated four times. A total of five tenderness detection values ​​at different positions of the tripe are obtained, and the average value is taken to see whether the tenderness of the tripe meets the corresponding standard, and finally the tenderness detection of the tripe is completed.

[0045] Embodiment 2

[0046] The difference between the second embodiment and the first embodiment is that: Figure 3 and Figure 4 As shown, a pressing mechanism is provided on the slide bar 5. In this embodiment, the pressing mechanism includes a slide plate 15, a pressing plate 16 and a pressing block 17. A horizontally arranged slide rail is fixedly connected to the support plate 1 by screws. The slide plate 15 is fixedly connected to the slide rail by screws, and a rib plate 18 is fixedly connected between the slider and the slide bar 5 by screws. When the quick clamp 4 is manually pushed, the slide plate 15 can be driven to slide horizontally on the support plate 1 by sliding the slide bar 5 left and right; the pressing plate 16 is fixedly connected to the slide plate 15 by screws, and the pressing plate 16 is L-shaped, with a slide groove on the pressing plate 16, and a protrusion matching the slide groove is integrally formed on the pressing block 17, so that the pressing block 17 can slide horizontally left and right along the slide groove, and an elastic member is provided between the pressure block 17 and the pressure plate 16. In this embodiment, the elastic member includes a compression spring 19 welded between the pressure block 17 and the pressure plate 16. When the compression spring 19 is in a natural state, the distance between the left side of the pressure block 17 and the baffle 3 is smaller than the distance between the ejector pin 2 and the baffle 3. When the tenderness of the tripe is tested, it is ensured that the pressure block 17 contacts the tripe on the baffle 3 first and the ejector pin 2 contacts the tripe later, so that the block squeezes and fixes the tripe before it is contacted by the ejector pin 2, preventing the tripe from being displaced when the ejector pin 2 pierces the tripe and affecting the detection accuracy.

[0047] like Figure 4As shown, a cleaning needle 20 is fixedly connected to the slide plate 15 by a screw. The cleaning needle 20 is located on the left side of the baffle 3 and is directly opposite to the socket 13 on the baffle 3. When the slide bar 5 of the quick clamp 4 is pulled to the right extreme position, the cleaning needle 20 will be inserted into the socket 13 driven by the slide plate 15, so as to prevent the ejector 2 from pushing the tripe debris into the socket 13 when detecting the tenderness of the tripe, so as to prevent the tripe debris from being blocked in the socket 13 and affecting the subsequent detection of the tenderness of the tripe; when the ejector 2 is used to pierce the tripe, the slide plate 15 slides to the left, causing the cleaning needle 20 to exit the socket 13 to the left, so as to prevent the cleaning needle 20 from interfering with the insertion of the ejector 2 into the socket 13.

[0048] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure or characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
