[0015] A method for detecting continuous weighing of a product includes the following steps: Step 1: The transmission mechanism is based on the conveyor table. The No. 2 motor drives the rotating shaft, which drives the outer roller to rotate. The outer roller meshes with the internal gear chain through gears to ensure stable rotation, which in turn drives the No. 1 belt and the No. 2 belt to transport products. When encountering irregular products, the No. 1 inclined block, spring and other structures in the No. 2 belt work together to make the sleeve fit the product and ensure smooth conveying. Step 2: In the pressurization mechanism, the No. 1 motor drives the lead screw, which controls the slide to drive the electric push rod to adjust the horizontal position. After the product is in place, the electric push rod presses down. At the same time, the rod plate assembly in the frame, with the magnetic assistance of the No. 1 and No. 2 magnetic blocks, stably squeezes the product, reducing weighing errors. The frame is used to store spare products. Step 3: The strip-shaped body of the control mechanism moves with the No. 1 belt, the hydraulic rod pushes the support to slide, and drives the No. 1 plate, extension plate and other components to move. Through the linkage between the components, such as the No. 1 plate contacting the moving rod, the squeezing slide plate causing the No. 2 plate to deflect, the precise control of the pressurization mechanism is achieved.
[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. The No. 2 belt and adaptive adjustment structure designed for irregular products can effectively solve the problem of conveyor offset or slippage caused by the unstable center of gravity of irregular products by elastically squeezing and conforming to the product contour; the sleeve plate automatically adjusts the fit according to the product shape, and at the same time, the No. 2 inclined block at the tail pushes the No. 1 inclined block to retract during the unloading stage, avoiding mechanical interference during unloading and improving the equipment's compatibility with diverse products.
[0017] 2. The hydraulic rod pushes the No. 1 plate to automatically fit the moving rod, moving synchronously with the transmission mechanism and applying pre-pressure to ensure that the pressurization action is completely synchronized with the product positioning, avoiding time difference errors caused by manual intervention. The specially designed bladder-decompression bladder buffer structure can absorb the impact force during product movement, preventing rigid compression from damaging the packaging, while achieving adaptive pressure adjustment through gas buffering.

[0030] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be understood that the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0031] Please see Figures 1 to 11 The present invention provides a technical solution: Example 1: Operation process of the transmission mechanism.
[0032] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, this embodiment focuses on the working process of the transmission mechanism 3. The conveyor table 31 is fixedly installed on the weighing and detection equipment 1. The groove 304 on its top is slidably adapted to the moving rod 27, providing guidance and space for the movement of the moving rod 27. The second motor 32 is fixedly installed on the outside of the conveyor table 31. Its output end is connected to the rotating shaft 33 through a coupling to realize power transmission. The outer roller 34 is fixedly connected to the outside of the rotating shaft 33. The gear 35 on the outside of the outer roller 34 meshes with the internal gear chain 36 to ensure the stable rotation of the outer roller 34. The outer side of the outer roller 34 is respectively squeezed and adapted to the first belt 37 and the second belt 38, which drive the belt to move and realize product conveying. The second belt 38 is designed for irregular products and products with small surface roughness, while ordinary packaged products are conveyed forward along the center part of the outer roller 34. The second belt 38 also increases the friction of the product during the conveying process and avoids slippage.
[0033] When conveying irregular products, the products squeeze the first inclined block 30 inside the second belt 38. The first inclined block 30 slides in the notch and compresses the spring 39. The sleeve 301 on the outside of the first inclined block 30 fits against the product, ensuring that the irregular products are conveyed smoothly and avoiding errors in subsequent weighing due to unstable center of gravity. When the product moves to the tail of the transmission mechanism 3, the second inclined block 302 keeps squeezing the first inclined block 30 during the movement, which is only implemented at the tail. At this time, the first inclined block 30 compresses the spring 39 and is completely retracted into the notch. At the same time, the sleeve 301 is away from the product and does not contact it, thus facilitating the unloading of the weighed product.
[0034] The transmission mechanism 3, through the connection and cooperation of various components, not only achieves stable conveying of conventional products, but also features an adaptive adjustment structure designed for irregular products. This design improves the equipment's compatibility with products of different shapes, avoids problems such as slippage and jamming of irregular products during conveying, ensures the continuity and stability of product conveying, and enhances the equipment's versatility and practicality.
[0035] Example 2: Working process of the pressurization mechanism.
[0036] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment details the operation of the pressurizing mechanism 2. The outer rail 21 is bolted to the outside of the table legs of the weighing and testing equipment 1, providing a stable mounting base for the pressurizing mechanism 2. A motor 22 is mounted on the outer end face of the outer rail 21, and its output end is connected to a lead screw 23 via a coupling. Bearings at both ends of the lead screw 23 are installed inside the outer rail 21 to ensure smooth rotation of the lead screw 23. A slide 24 is threaded onto the outer side of the lead screw 23, and an electric push rod 25 is fixedly installed on the top inner side of the slide 24. Rotation of the lead screw 23 drives the slide 24 to move horizontally, adjusting the position of the electric push rod 25. The top of the moving rod 27 is fixedly connected to the frame 28, and the inside of the frame 28 is fixedly connected to the partition plate 29, dividing the inside of the frame 28 into two cavities. The function of one cavity is to handle the high-altitude placement of a large number of products from the same batch. In short, one product is placed on the conveying mechanism 3 for transportation, while the other product is placed in the frame 28 for transportation, and the two are transported synchronously without affecting subsequent weighing and detection. The bottom of the inner cavity of the frame 28 is fixedly connected to the second magnetic block 20, and the bottom of the rod plate assembly 201 is inserted into the bottom. The bottom of the top plate of the rod plate assembly 201 is fixedly connected to the first magnetic block 26. When the product is transported to the designated position, the electric push rod 25 starts to extend, and the rod plate assembly 201 applies downward pressure to the top of the product. At the same time, under the action of magnetic force, the rod plate assembly 201 stably squeezes the product to ensure that the product is compact during weighing.
[0037] The pressurizing mechanism 2 achieves precise position adjustment of the electric push rod 25 through the screw 23-slide 24 structure. Combined with the magnetically assisted rod plate assembly 201, it can accurately control the downward pressure and position on the product according to different product sizes and weights. This design effectively reduces weighing errors caused by loose products, improves the accuracy of weighing detection, and provides reliable data support for product quantity confirmation.
[0038] Example 3: Adjustment process of the control mechanism.
[0039] like Figure 9 , Figure 10 and Figure 11 As shown, This embodiment illustrates the working principle of the control mechanism 4. A strip-shaped body 41 is fixedly connected to the outer end face of a first belt 37 and moves synchronously with the first belt 37. A support 43 inside the strip-shaped body 41 is connected to the outside of the strip-shaped body 41 via a hydraulic rod 406. The extension and retraction of the hydraulic rod 406 can push the support 43 to slide within the inner groove 42 of the strip-shaped body 41. A first plate 45 is rotatably mounted on the outside of a fixed shaft 44 inside the support 43, and an extension plate 47 is fixedly connected to the outside. The extension plate 47 slides and adapts to the outer groove of the strip-shaped body 41, with both ends fixedly connected to the strip-shaped body 41 via folding pieces 48. A second plate 40 is rotatably mounted on the outside of a shaft 49 inside the extension plate 47. The second plate 40 is connected to a sliding plate 402 via a universal joint seat 401, and the sliding plate 402 slides and adapts to the outer groove 46. When the moving rod 27 needs to be moved, the hydraulic rod 406 pushes the support 43 to extend outward, and the first plate 45 contacts the outer wall of the moving rod 27. When the transmission mechanism 3 conveys, the first plate 45 squeezes the moving rod 27 and moves together, thereby enabling the transmission mechanism 3, the squeezing mechanism 2 and the control mechanism 4 to move forward synchronously. When the moving rod 27 reaches the other end of the tank 304, the first plate 45 is continuously subjected to the reverse force of the sliding plate 402. At this time, the sliding plate 402, which originally supported the first plate 45, will cause the second plate 40 to deflect outward through the shaft 49 under the reverse force. The telescopic tube 403 squeezes the bladder 404, causing the bladder 404 to compress. After deflecting 12°-16°, the first plate 45 no longer squeezes the moving rod 27. Finally, the hydraulic rod 406 retracts, realizing precise control of the pressurizing mechanism 2.
[0040] The first plate 45 will extend completely from the strip 41, while the support 43 will extend partially. At the same time, the slide plate 402 will also detach from the external slot 46 and come into contact with the first plate 45. The universal joint seat 401 connecting the slide plate 402 and the second plate 40 has a certain degree of toughness in its joint rod part.
[0041] The function of the bladder 404 is as follows: During the movement of the moving rod 27, it will exert a reverse force on the first plate 45, and the reverse force will eventually be transmitted to the bladder 404. Therefore, the bladder 404 will cancel out the reverse force. However, when the moving rod 27 moves to the other end of the tank, the reverse force will reach its peak. At this time, the bladder 404 will contract due to the force, and some gas will enter the pressure relief bladder 405 for storage until the first plate 45 is no longer in contact with the moving rod 27, and the gas will return to the bladder 404.
[0042] The movable rod 27 can be reset by external electric drive, and at the same time, the retraction of the hydraulic rod 406 makes the control mechanism 4 disconnect from the pressurization mechanism 2, so that the device returns to the initial state.
[0043] The control mechanism 4, through hydraulic drive and multi-component linkage structure, achieves automated and precise control of the pressurizing mechanism 2. It eliminates the need for manual adjustment of the position and status of the pressurizing mechanism 2, automatically adjusting the pressurization operation according to product conveying progress and requirements. This improves the equipment's intelligence and work efficiency, reduces manual intervention, and lowers the risk of operational errors.
[0044] The working principle of this invention is as follows: When the product uninterrupted weighing and testing equipment is working, the transmission mechanism 3 first smoothly transports the product to the weighing and testing equipment 1. During the product transport process, the control mechanism 4 drives the pressurizing mechanism 2 to operate according to the set program, applying downward pressure to the product to ensure that the product is stable during weighing. Then, the weighing and testing equipment 1 weighs the product and confirms whether the number of products in the packaging box meets the standard through the weight data, thus realizing uninterrupted automated testing.
[0045] The transmission mechanism 3 is based on the conveyor table 31. After the second motor 32 on its outer side starts, it drives the rotating shaft 33 to rotate through the coupling. The rotating shaft 33 then drives the outer roller 34 to rotate. The gear 35 on the outer side of the outer roller 34 meshes with the internal gear chain 36 to ensure the stability of the rotation of the outer roller 34. The transmission mechanism 3 is equipped with multiple sets of tensioning wheels 305 to further limit the lateral deviation of the chain and ensure that the intermediate gear 35 and the internal gear chain 36 always maintain stable meshing without the risk of tooth disengagement. When the outer roller 34 rotates, the outer pressure-adapted first belt 37 and second belt 38 move accordingly to realize the conveying of the product. The transmission mechanism 3 is equipped with a pressure wheel 306. The function of the pressure wheel 306 is to press the belt downwards so that the belt fits tightly against the surface of the intermediate outer roller 34, further compensating for the problem of insufficient wrap angle. The function of the connecting strip 37 is to transfer the pressure of the pressure wheel 306 to the first belt 37 to the second belt 38. When conveying irregular products, the product squeezes the first inclined block 30 inside the second belt 38. The first inclined block 30 slides in the notch and compresses the spring 39, so that the sleeve 301 on the outside of the first inclined block 30 fits against the product. At the same time, the first inclined block 30 squeezes the matching second inclined block 302 to provide squeezing force, so that the first inclined block 30 compresses the spring 39 and is pulled into the notch. Then the sleeve 301 moves outward at the same time, ensuring that the irregular product can be smoothly conveyed outward at the end of the conveying process.
[0046] In the pressurizing mechanism 2, the outer rail 21 is fixed to the outside of the table leg of the weighing and testing equipment 1. After the first motor 22 is started, its output end drives the lead screw 23 to rotate under the support of the bearing through the coupling. When the lead screw 23 rotates, the slide 24, which is threaded to it, moves linearly along the outer rail 21. By controlling the rotation direction and number of rotations of the first motor 22, the position of the slide 24 can be precisely adjusted, thereby adjusting the position of the electric push rod 25 in the horizontal direction. When the product is transported to the designated position by the transmission mechanism 3, the electric push rod 25 is started, and its push rod extends to apply downward pressure to the top of the product. During the pressurization process, the connecting frame 28 at the top of the moving rod 27 plays an auxiliary role. The internal partition plate 29 of the connecting frame 28 divides it into two cavities, one of which can hold multiple unpackaged products as a spare product storage area. At the same time, the rod plate assembly 201 inserted at the bottom of the connecting frame 28 plays a role during pressurization. The first magnetic block 26 at the bottom of the top plate of the rod plate assembly 201 interacts with the second magnetic block 20 at the bottom of the inner cavity of the frame 28. When the electric push rod 25 applies a downward force to the rod plate assembly 201, the rod plate assembly 201 can more stably squeeze the product under the assistance of magnetic force, ensuring that the product is in a tight and stable state when weighing, and reducing the weighing error caused by the looseness of the product.
[0047] The strip-shaped body 41 of the control mechanism 4 is fixed to the outer end face of the first belt 37 and moves with the movement of the first belt 37. The support 43 inside the strip-shaped body 41 can slide within the inner groove 42 of the strip-shaped body 41 under the action of the hydraulic rod 406. When the hydraulic rod 406 extends and pushes the support 43 to slide outward, the first plate 45 rotatably mounted on the outside of the fixed shaft 44 inside, the extension plate 47 fixedly connected on the outside, and related components move in coordination. The extension plate 47 slides on the outer groove of the strip-shaped body 41, and the folding pieces 48 at both ends of it play a connecting and buffering role. The second plate 40 rotatably mounted on the outside of the shaft 49 inside the extension plate 47 slides within the outer groove 46 of the strip-shaped body 41 through the slide plate 402 connected by the universal joint seat 401, converting the movement of the support 43 into precise control of the pressurization mechanism 2.
[0048] For example, when the moving rod 27 needs to be moved together, the hydraulic rod 406 pushes the support 43 to extend outward. At this time, the first plate 45 will contact the outer wall of the moving rod 27. Through the forward conveying of the transmission mechanism 3, the first plate 45 will squeeze the moving rod 27 and move forward together. However, when the moving rod 27 moves to the other end of the trough 304, the first plate 45 will be subjected to force and squeeze the slide plate 402. Finally, the second plate 40 will deflect outward through the shaft 49. At the same time, the telescopic tube 403 will squeeze the bladder 404. Finally, the first plate 45 will no longer squeeze the moving rod 27 due to the deflection.
[0049] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any modifications made by those skilled in the art based on the above concepts without creative effort shall fall within the scope of protection of the present invention.

12. A method for detecting continuous product weighing, used in the continuous product weighing detection equipment as described in claim 11, characterized in that, Includes the following steps: Step 1: The transmission mechanism is based on the conveyor table. The No. 2 motor drives the rotating shaft, which drives the outer roller to rotate. The outer roller meshes with the internal gear chain through gears to ensure stable rotation, which in turn drives the No. 1 belt and the No. 2 belt to transport products. When encountering irregular products, the No. 1 inclined block, spring and other structures in the No. 2 belt work together to make the sleeve fit the product and ensure smooth conveying. Step 2: In the pressurization mechanism, the No. 1 motor drives the lead screw, which controls the slide to drive the electric push rod to adjust the horizontal position. After the product is in place, the electric push rod presses down. At the same time, the rod plate assembly in the frame, with the magnetic assistance of the No. 1 and No. 2 magnetic blocks, stably squeezes the product, reducing weighing errors. The frame is used to store spare products. Step 3: The strip-shaped body of the control mechanism moves with the No. 1 belt, the hydraulic rod pushes the support to slide, and drives the No. 1 plate, extension plate and other components to move. Through the linkage between the components, such as the No. 1 plate contacting the moving rod, the squeezing slide plate causing the No. 2 plate to deflect, the precise control of the pressurization mechanism is achieved.
