Description

Technical Field

[0001] This utility model relates to the field of konjac vermicelli production, and in particular to a device for testing the sealing strength of konjac vermicelli packaging. Background Technology

[0002] Konjac noodles are made from konjac flour. After production and drying, they need to be packaged in plastic bags. Because they need to be sterilized in a hot water tank after production, a certain amount of gas is usually injected into the packaging bags to ensure that the packaged konjac noodles can float on the water surface, facilitating automated feeding via conveyor belt.

[0003] Since bulging packaging has a clear visual characteristic, the traditional method is to manually inspect each batch of konjac noodle packaging for deflation to identify leaking packages. This method is labor-intensive, prone to omissions, and can only detect leaks, not assess the seal strength. Utility Model Content

[0004] This invention provides a device for detecting the sealing strength of konjac noodle packaging, which solves the problem of automated detection of the sealing strength of konjac noodle packaging.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a konjac vermicelli packaging sealing strength testing device, including a workbench, a fixed frame on the workbench, a plurality of vertical guide rods on the fixed frame, the lower ends of the guide rods being connected to the workbench, and a lifting plate, the lifting plate being slidably connected to each guide rod so that the lifting plate can move up and down, a positioning plate being provided below the lifting plate on the workbench, the positioning plate being provided with a plurality of positioning slots with indicator lights, each lifting plate being provided with a plurality of lower pressure plates that can extend and retract relative to the lifting plate, each lower pressure plate being provided above each positioning slot, and a plurality of positioning sensors for detecting the height of the lower pressure plates being provided on the workbench.

[0006] In the preferred embodiment, the positioning slots and the lower pressure plate are arranged in rows and columns. The positioning sensors are through-beam fiber optic sensors. Position sensors are arranged on the sides of each row and column of the positioning slots on the worktable. The positioning sensors are used to detect the vertical sidewalls of the lower pressure plate.

[0007] In a preferred embodiment, multiple sensor brackets are also provided. Each sensor bracket has a vertical waist-shaped groove, through which the positioning sensor passes and is fixed to the sensor bracket by a nut.

[0008] In the preferred embodiment, a servo electric cylinder is provided at the upper end of the fixed frame, and the lower end of the servo electric cylinder rod is connected to the lifting plate.

[0009] In the preferred embodiment, the lower end of the positioning plate is connected to an adjusting base plate, the adjusting base plate is slidably connected to each guide rod, and the adjusting base plate is provided with multiple threaded feet, the lower end of which rests against the worktable.

[0010] In the preferred embodiment, a first sliding rod is provided on the upper surface of the lower pressure plate, a sliding sleeve is provided on the lifting plate, the first sliding rod is slidably connected to the sliding sleeve, a spring is provided between the lower pressure plate and the lifting plate, and a limiting sleeve is provided on the upper surface of the lower pressure plate.

[0011] In the preferred embodiment, the lifting plate is further provided with a threaded sleeve, and the upper surface of the lower pressure plate is provided with a second slide rod. The sleeve and the second slide rod are slidably connected. The spring is sleeved on the second slide rod, with the lower end of the spring abutting against the lower pressure plate and the upper end of the spring abutting against the lower end of the spring.

[0012] The beneficial effects of this utility model are as follows: the lower pressure plate automatically applies a specific force to the vermicelli packaging, and the presence or absence of an indicator light can be used to determine whether the packaging bag is leaking air or bursting due to insufficient pressure, thereby determining the packaging sealing strength. The detection is accurate and can simultaneously determine both air leakage and sealing strength. The detection position is open and does not obstruct the view, allowing for direct manual assistance in judging the packaging bag's condition. This dual judgment makes the detection results more reliable. The working positions of the lifting plate and positioning plate, as well as the pressure of the lower pressure plate, are all adjustable, allowing for flexible adjustments based on working conditions.

[0019] like Figure 1-4A device for testing the sealing strength of konjac vermicelli packaging includes a workbench 1, a fixed frame 4 on the workbench 1, multiple vertical guide rods 401 on the fixed frame 4, the lower ends of the guide rods 401 being connected to the workbench 1, and a lifting plate 3, which is slidably connected to each guide rod 401 so that the lifting plate 3 can move up and down. A positioning plate 2 is provided below the lifting plate 3 on the workbench 1, and the positioning plate 2 is provided with multiple positioning slots 201 with indicator lights 7. Each lifting plate 3 is provided with multiple lower pressure plates 5 that can extend and retract relative to the lifting plate 3, and each lower pressure plate 5 is located above each positioning slot 201. The workbench 1 is also provided with multiple positioning sensors 6 for detecting the height of the lower pressure plates 5.

[0020] After the konjac noodles are packaged in bags and sealed with plastic, they are placed in the positioning slots 201. The lifting plate 3 descends, and the pressing plates 5 press down on the konjac noodle packaging bags. The lifting plate 3 stops, and the pressing plates 5 keep pressing the packaging bags tightly for a period of time. The indicator light 7 detects the height of the pressing plates 5. If the packaging bag leaks air, the pressing plate 5 at that point will continue to descend a certain distance. After being detected by the positioning sensor 6, the back-end controller transmits a signal to the indicator light 7, which lights up, indicating that the konjac noodle packaging bag in the positioning slot 201 is leaking air. Subsequently...

[0021] Subsequently, the lifting platform 3 rises to its original position, and staff remove the konjac vermicelli packaging bags from the illuminated areas. They manually screen for bags with obvious air leaks based on the degree of compression. Suspicious bags with minor leaks are re-inspected in the next batch, and the positions of the suspicious bags in the positioning slot 201 are marked. If the re-inspection is successful, the bag passes; if the alarm continues to sound at the location of the suspicious bag during re-inspection, it is deemed unqualified and removed.

[0022] In the preferred embodiment, the positioning groove 201 and the lower pressure plate 5 are arranged in a row and column manner. The positioning sensor 6 is a through-beam fiber optic sensor. Positioning sensors 6 are arranged on the side of each row and column of the positioning groove 201 on the worktable 1. The positioning sensors 6 are used to detect the vertical sidewall of the lower pressure plate 5.

[0023] The detection line of the through-beam fiber optic sensor is relatively thin. Initially, when aligned with the outer vertical wall of the lower pressure plate 5, the detection line is blocked. When the packaging belt leaks air, the lower pressure plate 5 descends, and the detection line is no longer blocked, allowing the sensor to detect the signal change.

[0024] Due to the large number of pressure plates 5, it would be too costly to install a laser displacement sensor for each pressure plate 5 to accurately detect its displacement. Furthermore, in practical applications, it has been found that the probability of sealing problems is relatively low, making laser displacement sensors unnecessary. Using cheaper fiber optic sensors, a single set can detect the height of a row or column of pressure plates 5. Even if only one bag is leaking, cross-row and cross-column detection can pinpoint the location of the leaking bag. In the rare case where multiple bags leak, subsequent manual intervention to remove the leaking bags, combined with re-inspection of the next batch, easily helps in identifying the leaking bags.

[0025] In a preferred embodiment, multiple sensor brackets 601 are also provided. Each sensor bracket 601 has a vertical waist-shaped groove 602. The positioning sensor 6 passes through the waist-shaped groove 602 and is fixed to the sensor bracket 601 by a nut.

[0026] The height of the positioning sensor 6 can be adjusted to align with the lower pressure plate 5. The outer wall of the positioning sensor 6 is threaded and can be fitted with nuts. Two nuts can be used to clamp the vertical mounting surface of the sensor bracket 601 in the middle to fix the height of the positioning sensor 6.

[0027] In the preferred embodiment, a servo electric cylinder 402 is provided on the upper end of the fixed frame 4, and the lower end of the cylinder rod of the servo electric cylinder 402 is connected to the lifting plate 3.

[0028] The servo electric cylinder can precisely control the descent position of the lifting plate 3, so that the packaging bag size can be changed, and the preset position of the lifting plate 3 when it is pressed down can also be adjusted.

[0029] In the preferred embodiment, the lower end of the positioning plate 2 is connected to an adjustment base plate 202, the adjustment base plate 202 is slidably connected to each guide rod 401, and the adjustment base plate 202 is provided with multiple threaded feet 203, the lower ends of the feet 203 abutting against the worktable 1.

[0030] Positioning plate 2 is placed on adjusting base plate 202 and positioned by positioning pins at four corners, making it easy to replace positioning plate 2.

[0031] The rotating foot 203 can adjust the height of the positioning plate 2, so that even if the servo electric cylinder 402 uses a low-cost ordinary cylinder, the height of the positioning plate 2 can be adjusted to accommodate packaging bags of different sizes.

[0032] Since the base plate 202 is slidably sleeved with the guide rod 401, the horizontal displacement will not change when the height is adjusted, thus preventing the lower pressure plate 5 from being misaligned with the positioning groove 201.

[0033] In the preferred embodiment, the upper end face of the lower pressure plate 5 is provided with a first sliding rod 501, the lifting plate 3 is provided with a sliding sleeve 301, the first sliding rod 501 and the sliding sleeve 301 are slidably connected, a spring 8 is provided between the lower pressure plate 5 and the lifting plate 3, and a limiting sleeve 503 is provided at the upper end of the lower pressure plate 5.

[0034] The limiting sleeve 503 can prevent the first slide rod 501 from dislodging from the slide sleeve 301 under the push of the spring 8.

[0035] In the preferred embodiment, the lifting plate 3 is further provided with a threaded sleeve 302, and the upper end face of the lower pressure plate 5 is provided with a second slide rod 502. The sleeve 302 and the second slide rod 502 are slidably sleeved together. The spring 8 is sleeved on the second slide rod 502, and the lower end of the spring 8 abuts against the lower pressure plate 5, while the upper end of the spring 8 abuts against the lower end of the spring 8.

[0036] The second slide bar 502 can restrict the spring 8 and prevent the spring 8 from coming out. The height of the screw sleeve 302 can be adjusted by rotation to change the initial compression of the spring 8.

[0037] When the packaging bag is pressed down, the spring 8 is compressed. First, it can act as a buffer to prevent the packaging bag from bursting due to excessive pressure. Second, the spring 8 causes the lower pressure plate 5 to exert a constant pressure on the packaging bag, and the pressure can be adjusted by the screw sleeve 302 to adapt to different specifications.

[0038] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
