Description

Technical Field

[0001] This utility model relates to the field of tableware quality testing technology, and in particular to a tableware quality testing organization. Background Technology

[0002] Tableware refers to non-edible utensils that come into direct contact with food during meals, used to assist in the distribution or consumption of food. Chopsticks are a type of tableware. Chopsticks require a certain level of strength to prevent breakage during use. Therefore, manufactured chopsticks need to undergo strength testing. Chopsticks are placed on a testing platform of an extrusion machine, and their compressive strength is tested by suspending both ends of the chopsticks in the air and compressing them. However, when chopsticks break, fragments splatter out, and these fragments, without any shielding, can easily cause injury to testing personnel. To address this, publication number CN222579791U discloses a tableware quality testing mechanism aimed at solving the technical problem of chopsticks splattering fragments when broken, which could easily injure testing personnel. The device includes a base, a frame mounted on the base, a hydraulic cylinder body mounted on the top of the frame, a connecting plate, pressure blocks, a worktable, and a placement structure. The connecting plate is positioned below the hydraulic cylinder body. Two pressure blocks are symmetrically fixed to the bottom side of the connecting plate. The worktable is fixed to the base. The placement structure is positioned on the worktable. The placement structure includes positioning block A and positioning block B. Positioning block A is fixed to the worktable. A placement groove is formed on the top side of positioning block A. Positioning block B is positioned above positioning block A. A chip-blocking groove is formed on the bottom side of positioning block B. This device has the advantage that when chopsticks are squeezed by the pressure blocks, the breakage occurs within the placement groove and the chip-blocking groove. The chip-blocking groove blocks the chips generated during the breakage, preventing chips from scattering. The tableware quality testing mechanism disclosed in the aforementioned patent reduces the risk of splashing by shielding the middle of the placed chopsticks. However, this shielding method is not ideal. During the testing process, it is difficult to ensure that the chopsticks break only in the middle, as there is a risk of breakage at the ends or other locations. Even with only shielding the middle, the risk of splashing still exists. In addition, there is no structure for automatically pressing and securing the chopsticks during testing, which can cause the chopsticks to wobble and shift during the squeezing process, thus affecting the stability of the testing. In view of the above, this application proposes a tableware quality testing mechanism. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a tableware quality inspection agency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A tableware quality testing organization includes: The testing station has an L-shaped support fixedly connected to its top; A hydraulic cylinder, fitted and fixed to the top of an L-shaped support, is used to provide vertical driving force. A support plate, the top of which is fixedly connected to the bottom end of the output shaft of the hydraulic cylinder; A shielding mechanism, mounted on a support plate, is used to shield the chopsticks being tested. The support and clamping mechanism is installed on the top of the testing platform and the shielding mechanism. The support and clamping mechanism is used to support and clamp the chopsticks. The pressure detection and control mechanism is installed at the bottom of the support plate and the top of the L-shaped support base, and is electrically connected to the hydraulic cylinder. The pressure detection and control mechanism is used to detect the strength of the chopsticks and the squeezing force during the detection process.

[0005] Preferably, the shielding mechanism includes a transparent protective cover with an opening at the bottom, which is used to completely shield and protect the chopsticks. L-shaped guide rods are fixedly connected to both sides of the top of the transparent protective cover. A support plate is slidably sleeved on the two L-shaped guide rods. The L-shaped guide rods provide vertical guidance for the transparent protective cover. Two first springs are fixedly connected between the bottom of the support plate and the top of the transparent shielding cover. The first springs are movably sleeved on the corresponding L-shaped guide rods, and the extension and contraction characteristics of the first springs provide vertical movement space for the support plate.

[0006] Preferably, the support and clamping mechanism includes a support base fixedly connected to the top of the testing platform, a clamping block above the support base, and both the support base and the clamping block having an arc-shaped structure on their adjacent sides and a first anti-slip rubber sheet bonded to them. The first anti-slip rubber sheet can effectively reduce slippage during the clamping process. A T-shaped positioning rod is fixedly connected to the top of the clamping block, which guides the clamping block. The transparent protective cover is slidably fitted onto the T-shaped positioning rod. A second spring is fixedly connected between the top of the clamping block and the inner wall of the top of the transparent protective cover. The second spring is movably fitted onto the T-shaped positioning rod, and the extension and contraction characteristics of the second spring provide vertical movement space for the transparent protective cover.

[0007] Preferably, the pressure detection and control mechanism includes two pressure sensors fixedly connected to the bottom of the support plate. A connecting rod is fixedly connected to the bottom of each pressure sensor. The pressure sensor is used to continue detecting the extrusion force. The bottom end of the connecting rod extends into the transparent protective cover and is fixedly connected to an extrusion block. The extrusion block extrudes the chopsticks. A PLC controller and a display screen are fixedly connected to the top of the L-shaped support base. The PLC controller is electrically connected to the hydraulic cylinder and the two pressure sensors. The display screen is electrically connected to the two pressure sensors. The pressure value detected by the pressure sensors is transmitted to the display screen for display.

[0008] Preferably, a second anti-slip rubber sheet is bonded and fixed to the bottom of the extrusion block. The properties of the second anti-slip rubber sheet reduce slippage during the extrusion process. Two rectangular perforations are opened on the top inner wall of the transparent protective cover, and the inner wall of the rectangular perforations slides in contact with the outer side of the corresponding connecting rod.

[0009] Preferably, the distance between the inner walls on both sides of the transparent protective cover is greater than the length of a regular chopstick.

[0010] Preferably, guide holes are provided on both sides of the top of the support plate, and the inner wall of the guide hole slides in contact with the outer side of the corresponding L-shaped guide rod.

[0011] Compared with existing technologies, the beneficial effects of this utility model are: By combining hydraulic cylinders, support plates, and support and clamping mechanisms, chopsticks can be clamped before testing. By clamping the chopsticks before the compression test, the shaking and displacement of the chopsticks during the test can be effectively reduced, and the stability of the test process can be improved. By setting up a shielding mechanism, the chopsticks can be completely shielded during testing. This complete shielding effectively avoids the risk of a chopstick breaking off at one point and scattering onto a person. The pressure detection control mechanism is used to perform compression tests on chopsticks, and to detect the compression force during the test. The pressure value is displayed on the screen so that personnel can intuitively understand the test results. This invention, through a series of structural designs, can compress chopsticks before compression testing, effectively reducing the likelihood of chopsticks shaking or shifting during testing and improving stability. Furthermore, it can completely shield the chopsticks during testing, effectively preventing the risk of a broken chopstick scattering onto a person, thus improving the protective effect and safety.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-3 A tableware quality testing institution, comprising: The testing station 1 has an L-shaped support base 2 fixedly connected to its top; Hydraulic cylinder 3 is embedded and fixed on the top of L-shaped support 2. Hydraulic cylinder 3 is used to provide vertical driving force. The top of the support plate 7 is fixedly connected to the bottom end of the output shaft of the hydraulic cylinder 3; The shielding mechanism 4 is installed on the support plate 7 and is used to shield the chopsticks being tested. The shielding mechanism 4 includes a transparent protective cover 401 with an opening at the bottom. The distance between the inner walls of the two sides of the transparent protective cover 401 is greater than the length of a regular chopstick. The transparent protective cover 401 is used to shield and protect the chopstick. L-shaped guide rods 402 are fixedly connected to both sides of the top of the transparent protective cover 401. The support plate 7 is slidably sleeved on the two L-shaped guide rods 402. Guide holes are opened on both sides of the top of the support plate 7. The inner wall of the guide hole slides in contact with the outer side of the corresponding L-shaped guide rod 402. The L-shaped guide rods 402 provide vertical guidance for the transparent protective cover 401. Two first springs 403 are fixedly connected between the bottom of the support plate 7 and the top of the transparent shielding cover 401. The first springs 403 are movably sleeved on the corresponding L-shaped guide rods 402. The extension and retraction characteristics of the first springs 403 provide vertical movement space for the support plate 7.

[0016] In this implementation scheme: the hydraulic cylinder 3 is opened in the forward direction, and the output shaft of the hydraulic cylinder 3 drives the support plate 7 to move downward. The support plate 7 drives the transparent protective cover 401 to move downward through two first springs 403. When the transparent protective cover 401 moves downward to the point where its bottom contacts the top of the testing table 1, the transparent protective cover 401 is restricted from moving further. At this time, the support plate 7, which continues to move, slides downward on the two L-shaped guide rods 402 and compresses the first springs 403. The first springs 403 squeeze the transparent protective cover 401 to achieve the pressure fixation of the transparent protective cover 401.

[0017] It should be noted that the model and type of hydraulic cylinder 3 are the same as those of the hydraulic cylinder disclosed in announcement number CN222579791U, and its working principle is the same. Alternatively, the first spring 403 can be selected with a spring force range of 0.1N-10N.

[0018] Furthermore: A tableware quality inspection mechanism includes a support and clamping mechanism 5, which is installed on the top of the inspection table 1 and a shielding mechanism 4. The support and clamping mechanism 5 includes a support base 501 fixedly connected to the top of the testing table 1. A clamping block 502 is provided above the support base 501. The sides of the support base 501 and the clamping block 502 that are close to each other are both designed with an arc shape and are bonded with a first anti-slip rubber. The first anti-slip rubber can effectively reduce slippage during the clamping process. A T-shaped positioning rod 503 is fixedly connected to the top of the clamping block 502. The T-shaped positioning rod 503 is used to guide the clamping block 502. A transparent protective cover 401 is slidably sleeved on the T-shaped positioning rod 503. The top inner wall of the transparent protective cover 401 is provided with a positioning hole that slides with the outer side of the T-shaped positioning rod 503. A second spring 504 is fixedly connected between the top of the clamping block 502 and the top inner wall of the transparent protective cover 401. The second spring 504 is movably sleeved on the T-shaped positioning rod 503. The extension and contraction characteristics of the second spring 504 provide vertical movement space for the transparent protective cover 401.

[0019] In this implementation scheme: when pressing the chopsticks, the chopsticks to be tested are placed on top of the support base 501. When the transparent protective cover 401 moves downward, the second spring 504 drives the pressing block 502 to move downward. The pressing block 502 drives the first anti-slip rubber on it to move downward until it contacts the chopsticks, thus restricting the pressing block 502 from moving further. At this time, the transparent protective cover 401, which continues to move, slides downward on the T-shaped positioning rod 503 and compresses the second spring 504. The second spring 504 squeezes the pressing block 502, thereby achieving the pressing of the chopsticks.

[0020] It should be noted that the second spring 504 can be selected from springs with a spring force range of 0.1N-10N.

[0021] Furthermore: A tableware quality inspection mechanism further includes a pressure detection control mechanism 6, which is installed at the bottom of the support plate 7 and the top of the L-shaped support seat 2, and is electrically connected to the hydraulic cylinder 3. The pressure detection and control mechanism 6 includes two pressure sensors 603 fixedly connected to the bottom of the support plate 7. A connecting rod 602 is fixedly connected to the bottom of each pressure sensor 603. The pressure sensors 603 are used to further detect the extrusion pressure. The bottom end of the connecting rod 602 extends into the transparent protective cover 401 and is fixedly connected to an extrusion block 601. Two rectangular perforations are formed on the top inner wall of the transparent protective cover 401. The inner walls of the rectangular perforations slide in contact with the outer sides of the corresponding connecting rods 602. A second anti-slip rubber sheet is bonded to the bottom of the extrusion block 601. The anti-slip rubber reduces slippage during the extrusion process. The chopsticks are extruded by the extrusion block 601, and the connecting rod 602 provides vertical guidance for the corresponding extrusion block 601. The top of the L-shaped support 2 is fixedly connected to the PLC controller 604 and the display screen 605. The PLC controller 604 is electrically connected to the hydraulic cylinder 3 and two pressure sensors 603. The display screen 605 is electrically connected to the two pressure sensors 603. The pressure value detected by the pressure sensors 603 is transmitted to the display screen 605 for display.

[0022] In this implementation scheme: As the support plate 7 continues to move downward, it sequentially drives two extrusion blocks 601 to move downward through two pressure sensors 603 and two connecting rods 602 to extrude pressure on both ends of the chopsticks. The strength of the chopsticks is detected by the extrusion. During the detection process, the chopsticks are observed to see if they are broken through the transparent shield 401. During the extrusion detection process, the pressure sensor 603 detects the extrusion force and transmits the detected extrusion force to the PLC controller 604 and the display screen 605. The display screen 605 is used to display the pressure value. When the extrusion force reaches the preset value and the chopsticks are still in good condition, the PLC controller 604 controls the hydraulic cylinder 3 to close, thereby completing the strength detection of the chopsticks.

[0023] It should be noted that: the pressure sensor 603 can preferably be Honeywell FSG15N1A, the display screen 605 can preferably be Weintek MT8071iE, and the PLC controller 604 can preferably be FX3U-32MT / ES-A. The specific control principle is as follows: the pressure sensor 603 feeds back the pressure value to the analog input channel of the PLC controller 604 in real time. The PLC controller 604 presets a chopstick strength threshold (e.g., 10N). When the pressure is ≥10N and the chopstick does not break, it triggers the shutdown of the hydraulic cylinder 3. If the pressure does not reach the threshold and the chopstick breaks, the PLC controller 604 records the fault and controls the solenoid valve of the hydraulic cylinder 3 to de-energize through digital output, stopping the downward pressure. The specific control principle is existing technology in this field and will not be elaborated on here.

[0024] Working principle: When testing chopsticks, the chopsticks to be tested are placed on top of the support base 501. Then, the hydraulic cylinder 3 is opened in the forward direction. The output shaft of the hydraulic cylinder 3 drives the support plate 7 to move downward. The support plate 7 drives the transparent protective cover 401 to move downward through two first springs 403. The transparent protective cover 401 drives the pressing block 502 to move downward through the second spring 504. The pressing block 502 drives the first anti-slip rubber on it to move downward until it contacts the chopsticks, which restricts the pressing block 502 from moving further. At this time, the transparent protective cover 401, which continues to move, slides downward on the T-shaped positioning rod 503 and compresses the second spring 504. The second spring 504 squeezes the pressing block 502, thereby pressing the chopsticks. By pressing the chopsticks before the pressing test, the shaking and displacement of the chopsticks during the test can be effectively reduced, and the stability of the test process can be improved. When the transparent protective cover 401 moves downwards until its bottom contacts the top of the testing platform 1, it restricts the transparent protective cover 401 from moving further. At this time, the support plate 7, which continues to move, slides downwards on the two L-shaped guide rods 402 and compresses the first spring 403. The first spring 403 squeezes the transparent protective cover 401 to achieve the pressure fixation of the transparent protective cover 401. At this time, the transparent protective cover 401 covers and protects the entire chopstick. By covering the entire chopstick, the risk of the chopstick breaking and splashing onto people can be effectively avoided, thus improving the protection effect and safety. The pressure value for closing the hydraulic cylinder 3 is preset via the PLC controller 604. As the support plate 7 continues to move downward, it sequentially drives the two extrusion blocks 601 downward via two pressure sensors 603 and two connecting rods 602. As the two extrusion blocks 601 move downward, they extrude pressure on both ends of the chopsticks. The strength of the chopsticks is tested by the extrusion. During the test, the chopsticks are observed to see if they are broken through the transparent shield 401. During the extrusion test, the pressure sensor 603 detects the extrusion force and transmits the detected extrusion force to the PLC controller 604 and the display screen 605. The display screen 605 is used to display the pressure value. When the extrusion force reaches the preset value and the chopsticks are still intact, the PLC controller 604 controls the hydraulic cylinder 3 to close, thereby completing the strength test of the chopsticks.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
