Description

Technical Field

[0001] This utility model relates to the field of food testing technology, specifically a rapid food testing device. Background Technology

[0002] Puffed snacks, such as potato chips and shrimp crackers, are popular with consumers for their crispy texture and diverse flavors. These foods typically use gas-filled packaging technology, filling the packaging with gases such as air or nitrogen to cushion the food during transportation and storage, prevent breakage, and extend shelf life. Therefore, the airtightness of the packaging is crucial for maintaining the quality and taste of puffed snacks; testing these foods generally involves checking for any air leaks.

[0003] Currently, in existing technologies, the detection of puffed food typically involves transporting the food to a detection device via a conveyor belt, then pressing down on the food. A pressure sensor within the device detects changes over a certain time to determine if the food is leaking air. To enable rapid detection, the power source for this device is usually a cylinder. However, because the cylinder stroke is fixed, the pressure applied by the device is also fixed. This results in larger puffed foods being subjected to greater compression, potentially causing air to burst the packaging and leading to product waste. Therefore, a rapid food detection device is proposed. Utility Model Content

[0004] The main objective of this invention is to provide a rapid food testing device that can solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention proposes a rapid food testing device, comprising a frame and a conveyor belt. A fixed frame is fixedly mounted on the frame, and a positioning component, a testing mechanism, and auxiliary testing components are provided on the fixed frame. The testing mechanism includes:

[0006] Mounting plate, the mounting plate is fixedly mounted on the frame, and a cylinder is fixedly mounted on the mounting plate;

[0007] Plate 1, which is fixed to the output end of the cylinder, is penetrated by a guide rod and slidably connected to the guide rod, and a limit nut is threadedly connected to the threaded part of the guide rod;

[0008] Plate 2 is fixedly connected to the bottom of the guide rod. A pressure sensor is fixedly connected to the lower side of Plate 2, and a pressure plate is fixedly connected to the side of the pressure sensor away from Plate 2.

[0009] Preferably, the first plate and the second plate are elastically connected by a connecting spring, the connecting spring is sleeved on the outside of the guide rod, and a wedge block is fixedly connected to the outer wall of the first plate.

[0010] Preferably, the positioning component includes a fixing plate, which is fixedly connected to the outer wall of the frame. An electric cylinder is fixedly installed on the outer wall of the fixing plate, and a positioning element is fixedly connected to the output end of the electric cylinder.

[0011] Preferably, the side of the positioning member away from the electric cylinder is V-shaped, and the puffed food can be positioned below the detection mechanism by the V-shaped positioning member.

[0012] Preferably, the auxiliary detection component includes a limiting sleeve, which is fixedly connected to the outer wall of the electric cylinder. The limiting sleeve is penetrated by a straight rod and slidably connected to the straight rod. One end of the straight rod is provided with a rotating wheel, and the other end of the straight rod is fixedly connected to a horizontal plate. The horizontal plate and the limiting sleeve are elastically connected by a return spring.

[0013] Preferably, a hinge rod is hinged to the side of the horizontal plate away from the vertical rod, and a vertical rod is hinged to the end of the hinge rod away from the horizontal plate. A round rod is fixedly connected to the bottom outer wall of the vertical rod.

[0014] Preferably, a bracket is fixedly connected to the outer wall of the frame, and a swing rod is hinged to the bracket. A sliding groove is provided on the outer wall of the swing rod, and the round rod is slidably connected in the sliding groove.

[0015] Preferably, a sliding plate is slidably connected to the inner surface of the frame, and the lower side of the sliding plate abuts against the end of the swing rod.

[0016] Preferably, the wedge block is located above the rotating wheel. During the descent of the wedge block, the wedge block presses against the rotating wheel, the straight rod drives the horizontal plate to move, and stretches the return spring.

[0017] This invention provides a rapid food testing device. It has the following beneficial effects:

[0018] (1) The food rapid detection device allows the position of the limit nut to be adjusted on the guide rod through the use of the detection mechanism, thereby making the height of the guide rod adjustable to adapt to puffed foods of different sizes. After the limit nut abuts against the mounting plate, when the output end of the cylinder continues to extend, the first plate will squeeze the connecting spring, while the second plate will not move, preventing the puffed food from being crushed, ensuring the detection effect of the device, and reducing product waste.

[0019] (2) The food rapid detection device uses auxiliary detection components. During the process of the plate descending, the swing rod can swing so that the sliding plate can rise and abut against the conveyor belt, thereby preventing the deformation of the conveyor belt when the puffed food is squeezed and affecting the detection of the puffed food. When the plate rises, the swing rod can reset and the sliding plate descends and separates from the conveyor belt, preventing the subsequent conveyor belt from rubbing against the sliding plate, reducing the wear of the conveyor belt and extending its service life.

[0028] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5 This utility model proposes a rapid food testing device, including a frame 1 and a conveyor belt 2. The frame 1 is also provided with the drive component and transmission component required for the conveyor belt 2. The drive component is a motor and the transmission component is a transmission roller, which is prior art and will not be described in detail. A fixing frame 3 is fixedly installed on the frame 1. The fixing frame 3 is provided with a positioning component 4, a testing mechanism 5 and an auxiliary testing component 6.

[0031] In this embodiment of the present invention, in order to transport the puffed food to the area below the detection mechanism 5, the positioning component 4 specifically includes a fixing plate 41, which is fixedly connected to the outer wall of the frame 1. An electric cylinder 42 is fixedly installed on the outer wall of the fixing plate 41, and a positioning component 43 is fixedly connected to the output end of the electric cylinder 42. The side of the positioning component 43 away from the electric cylinder 42 is V-shaped. The puffed food is transported by the conveyor belt 2, and the electric cylinder 42 drives the positioning component 43 to move, so that the transported puffed food can be moved to the area below the detection mechanism 5.

[0032] Furthermore, in order to detect puffed foods of different sizes, the detection mechanism 5 specifically includes a mounting plate 51, a first plate 53, and a second plate 56. The mounting plate 51 is fixedly mounted on the frame 1, and a cylinder 52 is fixedly mounted on the mounting plate 51. The first plate 53 is fixed to the output end of the cylinder 52. The cylinder 52 is connected to an external air source device, the installation and debugging of which are existing technologies and will not be described in detail. The first plate 53 is penetrated by a guide rod 54 and is slidably connected to the guide rod 54. A limit nut 55 is threadedly connected to the threaded part of the guide rod 54. The second plate 56 is fixedly connected to the bottom of the guide rod 54. A pressure sensor 57 is fixedly connected to the lower side of the second plate 56. A pressure plate 58 is fixedly connected to the side of the pressure sensor 57 away from the second plate 56. By rotating... The limiting nut 55 is adjusted to position the guide rod 54, allowing the guide rod 54 to descend to an adjustable height to accommodate different sizes of puffed food. By activating the cylinder 52, the first plate 53 descends, causing the second plate 56 and guide rod 54 to descend as well. After the limiting nut 55 abuts against the mounting plate 51, as the output end of the cylinder 52 continues to extend, the first plate 53 compresses the connecting spring, while the second plate 56 stops moving, preventing the puffed food from bursting. This ensures the detection effect of the device and reduces product waste. During the continuous compression of the puffed food by the pressure plate 58, the pressure sensor 57 displays a reading. If the pressure sensor 57 remains relatively stable within a certain time, it indicates that the puffed food is well-sealed; conversely, if it remains stable, it indicates that the puffed food is poorly sealed.

[0033] Furthermore, plate 1 53 and plate 2 56 are elastically connected by a connecting spring, which is sleeved on the outside of guide rod 54. A wedge block 59 is fixedly connected to the outer wall of plate 1 53. The auxiliary detection component 6 includes a limiting sleeve 61, which is fixedly connected to the outer wall of electric cylinder 42. The limiting sleeve 61 is penetrated by a straight rod 62 and is slidably connected to the straight rod 62. One end of the straight rod 62 is provided with a rotating wheel 63, and the other end of the straight rod 62 is fixedly connected to a horizontal plate 64. 64 and the limiting sleeve 61 are elastically connected by a return spring. A hinge rod 65 is hinged to the side of the horizontal plate 64 away from the straight rod 62. A vertical rod 66 is hinged to the end of the hinge rod 65 away from the horizontal plate 64. The vertical rod 66 is slidably connected to the outer shell of the electric cylinder 42 via a guide rail. A round rod 67 is fixedly connected to the bottom outer wall of the vertical rod 66. A bracket 69 is fixedly connected to the outer wall of the frame 1. A swing rod 68 is hinged to the bracket 69. A sliding groove is opened on the outer wall of the swing rod 68, and the round rod 67 slides... The frame 1 is slidably connected to a sliding plate 7 in the slide groove. The lower side of the sliding plate 7 abuts against the end of the swing rod 68. The wedge block 59 is located above the rotating wheel 63. As the plate 53 descends, the wedge block 59 descends. During the descent of the wedge block 59, the wedge block 59 presses against the rotating wheel 63. The straight rod 62 drives the horizontal plate 64 to move, stretching the return spring and driving the hinge rod 65 to move. Since the vertical rod 66 is slidably connected to the electric cylinder 42 through the guide rail... On the outer casing, the vertical rod 66 moves downward, causing the round rod 67 to move in the chute, which drives the swing rod 68 to swing, allowing the sliding plate 7 to rise and abut against the conveyor belt 2. This prevents the conveyor belt 2 from deforming when the puffed food is squeezed, thus affecting the detection of the puffed food. When the plate 53 rises, the swing rod 68 returns to its original position, and the sliding plate 7 falls away from the conveyor belt 2, preventing friction between the sliding plate 7 and the subsequent conveyor belt 2 during transport, reducing the wear of the conveyor belt 2, and extending its service life.

[0034] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.

[0035] In use, the puffed food is conveyed by the conveyor belt 2, and then the positioning component 43 is moved by the electric cylinder 42, so that the conveyed puffed food can be moved to the bottom of the detection mechanism 5. Then the cylinder 52 is activated to drive plate 1 53 to descend, which in turn drives plate 2 56 and guide rod 54 to descend. After the limit nut 55 abuts against the mounting plate 51, when the output end of the cylinder 52 continues to extend, plate 1 53 will squeeze the connecting spring, while plate 2 56 will stop moving, preventing the puffed food from bursting, ensuring the detection effect of the device, and reducing product waste. During the continuous squeezing of the puffed food by the pressure plate 58, the pressure sensor 57 displays a reading. If the pressure sensor 57 shows basically no fluctuation within a certain period of time, it proves that the puffed food is well sealed; otherwise, it proves that the puffed food is not well sealed, thus realizing the detection of the puffed food. In the food inspection process, the plate 53 descends, causing the wedge block 59 to descend as well. During the descent of the wedge block 59, it presses against the rotating wheel 63. The straight rod 62 drives the horizontal plate 64 to move, stretching the return spring and causing the hinge rod 65 to move. Since the vertical rod 66 is slidably connected to the outer shell of the electric cylinder 42 via the guide rail, the vertical rod 66 moves downward, causing the round rod 67 to move in the slide groove. This causes the swing rod 68 to swing, allowing the sliding plate 7 to rise and abut against the conveyor belt 2. This prevents the conveyor belt 2 from deforming when the puffed food is squeezed, thus affecting the inspection of the puffed food. When the plate 53 rises, the swing rod 68 returns to its original position, and the sliding plate 7 descends and separates from the conveyor belt 2, preventing friction between the conveyor belt 2 and the sliding plate 7 during subsequent conveying and reducing wear on the conveyor belt 2.

[0036] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
