Description

Technical Field

[0001] The present invention relates to the technical field of food safety detection, and in particular to a sampling device for food quality and safety detection. Background Art

[0002] Fruits are common foods in daily life. During the growing process, pesticides such as insecticides and fungicides are usually used. In order to prevent the pesticide residues on the surface of fruits from affecting consumers' food safety, fruits are usually required to be sampled and tested before they can be sold. In order to facilitate the testing of fruits, operators usually use sampling devices to sample the fruits. Existing sampling devices usually consist of a carrying plate, a support base, a fixing rod, a connecting base, a working plate and a slicing knife.

[0003] For example: The utility model with application number CN202121108034.4 discloses a sampling device for food quality and safety testing, which specifically includes a horizontal supporting plate, on which two plate bodies are symmetrically installed, and the fruit can be placed between the two plate bodies, and a sliding plate that can move in the vertical direction is installed on the plate body, and a fixed rod that can move in the horizontal direction is installed on the sliding plate. The utility model is provided with movable fixed rods on both sliding plates, and the sliding plates can move in the vertical direction on the plate bodies, so that the fruit placed between the two plate bodies can be fixed, and the height of the sliding plate can be adjusted according to the size of the fruit. After the fruit is fixed, the two blades can be moved downward to cut a sheet sample from the fruit. This design avoids the hand injury of the hand knife when the handheld knife is used for slicing and sampling.

[0004] However, in order to facilitate fruit sampling, the slicing knife of the existing sampling device is usually exposed when not in use. Operators may accidentally touch the slicing knife and get injured when cleaning or carrying the sampling device. At the same time, the exposed blade is prone to absorb dust and other debris when idle, causing contamination of the sample during subsequent sampling, affecting the accuracy of the test results, and making it inconvenient to use. Summary of the Invention

[0005] In view of this, the present invention provides a sampling device for food quality and safety testing, which has a protective shell that can protect the slicing knife when the slicing knife is not in operation. By pressing down a control handle, the control handle drives the sampling slide to move and compress a return spring. As the sampling slide moves, the slicing knife moves to slice and sample a fixed fruit sample. During the movement of the sampling slide, the control rack is driven to move. As the control rack moves, the control rack is driven to move. As the control rack moves, the control gear meshed with the control rack is driven to rotate. As the control gear rotates, the transmission shaft is driven to rotate. As the transmission shaft rotates, the first bevel gear is driven to rotate. As the first bevel gear rotates, the second bevel gear meshed with the control rack is driven to rotate. The rotation of the second bevel gear drives the protective shell to flip over, and the protective shell is opened to allow the slicing knife to slice the fruit sample. After slicing is completed, the control handle is released. At this time, the sampling slide is reset as the return spring rebounds. As the return spring rebounds, the control rack drives the control gear to rotate in the opposite direction, thereby automatically closing the protective shell to protect the slicing knife.

[0046] Specific usage and function of this embodiment: In the present invention, when conducting food quality and safety testing on fruit samples, the fruit samples are placed on the carrying plate 102, and the fixing rod 112 is rotated to move horizontally. As the fixing rod 112 moves horizontally, it is inserted into the fruit sample to fix the fruit sample. The setting of the drainage groove 103 can drain the juice generated when the fruit sample is sliced. The setting of the enclosure body 101 can prevent the fruit juice from flowing out. The setting of the installation slider 107 and the installation slide 105 can make the mounting seat 106 slide in the support seat 104, and the height of the mounting seat 106 can be adjusted so that the fixing rod 112 can be To fix irregular shaped fruits, the position of the mounting slide 107 can be locked by setting the locking plug rod 108 and the locking socket 111, and then the position of the mounting seat 106 can be locked. When adjusting the height of the mounting seat 106, the connecting plate 109 is pulled to make the connecting plate 109 pull the locking plug rod 108 to move and stretch the connecting spring 110. As the locking plug rod 108 moves, it will disengage from the locking socket 111, releasing the limit of the mounting slide 107. At this time, the operator can slide the mounting seat 106 to adjust the height of the fixing rod 112. After the height adjustment of the fixing rod 112 is completed, the connecting plate 109 is released, and the connecting plate 109 is reset with the rebound of the connecting spring 110, so that the locking The height of the fixing rod 112 can be fixed by inserting the stop rod 108 into the locking socket 111 aligned with the position thereof, and the control handle 119 is pressed down to drive the sampling slide 115 to move and squeeze the return spring 116. As the sampling slide 115 moves, the slicing knife 117 is driven to move to slice and sample the fixed fruit sample. In the process of the movement of the sampling slide 115, the control rack 127 is driven to move, and as the control rack 127 moves, the control gear 129 meshed with it is driven to rotate. As the control gear 129 rotates, the transmission shaft 128 is driven to rotate. As the transmission shaft 128 rotates, the first bevel gear 130 is driven to rotate. The rotation of the gear 130 drives the second bevel gear 131 meshing with it to rotate, and the rotation of the second bevel gear 131 drives the protective shell 132 to flip over, opening the protective shell 132 so that the slicing knife 117 can slice the fruit sample. After the slicing is completed, it is only necessary to release the control handle 119. At this time, the sampling slide 115 will be reset as the return spring 116 rebounds. As the return spring 116 rebounds, the control rack 127 drives the control gear 129 to rotate in the opposite direction, thereby automatically closing the protective shell 132 to protect the slicing knife 117. The protective shell 132 can be sealed by the setting of the sealing block 134, and the sealing block 134 will be squeezed during the movement of the sampling slide 115.The sealing block 134 slides in the fixed seat 133, squeezing the auxiliary spring 135 to prevent the sealing block 134 from affecting the flipping of the protective shell 132.

When the protective shell 132 is hit, it can absorb the impact force to ensure the impact resistance of the protective shell 132. The slicing knife 117 is made of 304 stainless steel (hardness HRC50-55), and the protective shell 132 is made of food-grade ABS engineering plastic (flame retardant grade V0). The control gear 129 and the control rack 127 have a module of 2 and a gear ratio of 1:1, ensuring that the flip angle of the protective shell 132 is 90°.

[0047] Example 2: Based on Example 1, please refer to Figures 12 to 16 As shown, it includes: a wiping pad 122, a disassembly slider 123, a disassembly slot 124, a limit block 125 and a control torsion spring 126. A wiping pad 122 is provided in each of the two mounting frames 121; the two wiping pads 122 are aligned with the positions of the two slicing knives 117 respectively; a group of disassembly sliders 123 are fixedly connected to the outside of the two mounting frames 121; two groups of disassembly slots 124 are symmetrically opened in the mounting plate 120; the two groups of disassembly sliders 123 are slidably connected in the two groups of disassembly slots 124 respectively.

[0048] Among them, two limit blocks 125 are symmetrically connected to the mounting plate 120 for rotation; the two limit blocks 125 are aligned with the positions of the two mounting frames 121 respectively; the outside of the rotating shafts of the two limit blocks 125 are symmetrically fixedly connected with a group of control torsion springs 126; the ends of the two groups of control torsion springs 126 are fixedly connected to the mounting plate 120.

[0049] Specific usage and function of this embodiment: In the present invention, the setting of the wiping pad 122 can wipe off the juice and fruit debris attached to the outside of the slicing knife 117 during the resetting process of the slicing knife 117. At the same time, the setting of the disassembly slider 123 and the disassembly slide groove 124 can facilitate the operator to remove the mounting frame 121 to replace the wiping pad 122. By controlling the setting of the torsion spring 126, the limiting block 125 can limit the mounting frame 121. When the wiping pad 122 needs to be replaced, the mounting frame 121 can be removed by simply flipping the limiting block 125 to expose the mounting frame 121.
