Technical Field

[0001] This utility model relates to the field of breast milk bag detection technology, and in particular to an online defective breast milk bag rejection device. Background Technology

[0002] Breast milk bags are food-grade, sterile plastic bags used to safely store expressed breast milk. They are typically made of polyethylene (PE), have good sealing properties, and are easy to freeze or refrigerate, ensuring the hygiene of the breast milk and maintaining its nutritional components, allowing mothers flexible feeding options for their babies.

[0003] A search revealed Chinese Patent CN211637359U, which discloses a defective food plastic packaging bag rejection device, relating to the field of detection device technology. Its key technical features include an inspection component and a rejection component arranged along the material conveying direction. The rejection component includes a frame, a turntable mounted on the frame, and a motor mounted on the frame that drives the turntable to rotate. Suction cups are arranged at equal angular intervals along the circumference of the turntable. When the inspection component detects a defective product, the turntable rotates, and the suction cups rotate to one side of the conveyor belt, adsorbing the defective packaging bag and rejecting it from the conveyor belt. This solution addresses the problems of low efficiency, excessive labor consumption, and increased production costs associated with manual rejection in existing technologies.

[0004] In the aforementioned existing technical solution, the rotating turntable causes the suction cup to rotate to one side of the conveyor belt, adsorbing defective packaging bags and removing them from the conveyor belt. However, in actual use, after the breast milk bags are produced, there may be some wrinkles on the surface, resulting in gaps between the suction cup and the breast milk bag, which prevents the suction cup from picking up the breast milk bag and removing the defective product. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model proposes an online defective product rejection device for breast milk bags. By extending the extension end of the impact hydraulic rod, the push rod impacts the side wall of the placement plate, causing the placement plate to rotate around the connecting rope. The breast milk bags placed on top of the placement plate fall into the storage box as the placement plate flips, facilitating the collection and processing of defective products and avoiding the situation where defective products cannot be rejected.

[0006] The technical solution to achieve the purpose of this utility model is: an online defective product rejection device for breast milk bags, including a conveying device, a fixed bracket fixedly installed on the top wall of the conveying device, a detection device fixedly installed on the inner top wall of the fixed bracket, a storage frame slidably installed on the side wall of the conveying device, and a conveying component provided inside the conveying device, the conveying component including;

[0007] Placement plates, there are multiple placement plates, and the multiple placement plates are evenly distributed inside the conveying device;

[0008] A connecting rope is provided inside the conveying device. The connecting rope is looped around the side wall of the drive shaft inside the conveying device and passes through the interior of multiple placement plates.

[0009] The bottom of the fixed bracket is equipped with a flip component, which is aligned with the storage box. The flip component includes:

[0010] A receiving groove is formed on the inner wall of the conveying device. A push rod is slidably installed inside the receiving groove, and the side wall of the push rod near the placement plate is inclined.

[0011] An impact hydraulic rod is fixedly installed on the outer side wall of the conveying device, and the extended end of the impact hydraulic rod is fixedly connected to the side wall of the push rod.

[0012] In some embodiments, a positioning component is provided at the bottom of the fixing bracket, the positioning component including;

[0013] A positioning strip that slides through the side wall of the fixed bracket and fits against the top wall of the placement plate;

[0014] A reset groove is formed on the top wall of the conveying device. Limiting rods are fixedly installed on the side wall of the positioning bar and the push rod. The limiting rods on the positioning bar are slidably installed inside the reset groove, and the limiting rods are fixedly installed on the bottom wall of the positioning bar.

[0015] In some embodiments, the positioning component further includes;

[0016] The linkage rotating rod is rotatably installed inside the receiving groove, and its upper and lower ends are respectively in contact with the side walls of the two limiting rods.

[0017] In some embodiments, a return spring is fixedly connected to the side wall of the limiting rod.

[0018] In some embodiments, a support bar is fixedly installed on the inner sidewall of the conveying device. The support bar is in contact with the bottom wall of the placement plate, and there is a notch at the position where the support bar is aligned with the push rod.

[0020] Compared with the prior art, the significant advantages of this utility model are:

[0021] Firstly, this invention facilitates the inspection of breast milk bags by placing them at the bottom of the detection device. When the detection device detects a defective breast milk bag, it extends the hydraulic rod to impact the side wall of the placement plate. The placement plate then rotates around the connecting rope, causing the breast milk bag placed on top of the placement plate to fall into the storage box. This facilitates the collection and processing of defective products and avoids situations where defective products cannot be removed. This invention solves the problem that existing rejection devices may not be able to remove defective products.

[0022] Secondly, this utility model uses the extension of the positioning strip to press against the top wall of the placement plate, thus fixing the position of the placement plate and preventing it from flipping due to accidental contact. When the impact hydraulic rod pushes the push rod to move, the limit rod on the push rod will push the linkage rotating rod to rotate. The top of the linkage rotating rod pushes the positioning strip to move away from the placement plate, so the positioning strip will not block the top wall of the placement plate, making it easier for the placement plate to flip.

[0030] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0031] This utility model provides an improved online defective breast milk bag rejection device. The technical solution of this utility model is as follows:

[0032] like Figures 1-4 As shown, the online defective product rejection device for breast milk bags includes a conveying device 1, a fixed bracket 4 is fixedly installed on the top wall of the conveying device 1, a detection device 5 is fixedly installed on the inner top wall of the fixed bracket 4, a storage frame 15 is slidably installed on the side wall of the conveying device 1, and a conveying assembly is provided inside the conveying device 1, which includes a placement plate 2 and a connecting rope 3.

[0033] There are multiple placement plates 2, which are evenly distributed inside the conveying device 1;

[0034] The connecting rope 3 is installed inside the conveying device 1. The connecting rope 3 is sleeved on the side wall of the drive shaft inside the conveying device 1, and the connecting rope 3 passes through the interior of multiple placement plates 2.

[0035] The breast milk bag to be tested is placed on the side wall of the placement plate 2. Since the connecting rope 3 connects multiple placement plates 2 together, and the placement plate 2 is placed on the side wall of the drive shaft on the conveying device 1, it is convenient to transport the breast milk bag on the top of the placement plate 2. By sending the breast milk bag to the bottom of the testing device 5, it is convenient for the testing device 5 to inspect the breast milk bag.

[0036] The bottom of the fixed bracket 4 is provided with a flipping component, which is aligned with the storage frame 15. The flipping component includes a receiving groove 8 and an impact hydraulic rod 7.

[0037] The receiving groove 8 is opened on the inner wall of the conveying device 1. A push rod 9 is slidably installed inside the receiving groove 8. The side wall of the push rod 9 near the placement plate 2 is inclined.

[0038] The impact hydraulic rod 7 is fixedly installed on the outer side wall of the conveying device 1, and the extended end of the impact hydraulic rod 7 is fixedly connected to the side wall of the push rod 9.

[0039] When the detection device 5 detects that the breast milk bag is defective, the extension end of the impact hydraulic rod 7 extends, causing the push rod 9 to impact the side wall of the placement plate 2. As a result, the placement plate 2 will rotate around the connecting rope 3, and the breast milk bag placed on top of the placement plate 2 will fall into the storage box 15 as the placement plate 2 flips, making it easier to collect and process the defective products.

[0040] like Figures 1-4 As shown, in this embodiment, a positioning component is provided at the bottom of the fixed bracket 4. The positioning component includes a positioning strip 10, a reset groove 11, and a linkage rotating rod 14.

[0041] The positioning strip 10 slides through the side wall of the fixed bracket 4 and fits against the top wall of the placement plate 2;

[0042] The reset groove 11 is opened on the top wall of the conveying device 1. Limiting rods 12 are fixedly installed on the side wall of the positioning bar 10 and the push rod 9. The limiting rods 12 on the positioning bar 10 are slidably installed inside the reset groove 11. The limiting rods 12 are fixedly installed on the bottom wall of the positioning bar 10. A reset spring 13 is fixedly connected to the side wall of the limiting rod 12.

[0043] The linkage rod 14 is rotatably installed inside the receiving groove 8, and the upper and lower ends of the linkage rod 14 are respectively in contact with the side walls of the two limiting rods 12;

[0044] The positioning strip 10 extends and presses against the top wall of the placement plate 2 to fix the position of the placement plate 2, preventing the placement plate 2 from flipping due to accidental contact. When the impact hydraulic rod 7 pushes the push rod 9 to move, the limit rod 12 on the push rod 9 will push the linkage rotating rod 14 to rotate. The top of the linkage rotating rod 14 pushes the positioning strip 10 to move away from the placement plate 2. Therefore, the positioning strip 10 will not block the top wall of the placement plate 2, making it easier for the placement plate 2 to flip.

[0045] By utilizing the elasticity of the return spring 13, the positioning bar 10 is pushed closer to the placement plate 2. When the linkage rotating rod 14 no longer abuts against the limit rod 12 on the positioning bar 10, the positioning bar 10 can easily return to its original position.

[0046] like Figures 1-4 As shown, in this embodiment, a support bar 16 is fixedly installed on the inner side wall of the conveying device 1. The support bar 16 is attached to the bottom wall of the placement plate 2, and there is a notch at the position where the support bar 16 is aligned with the push rod 9. The support bar 16 supports the bottom end of the placement plate 2, ensuring that the placement plate 2 can stably convey the breast milk bag. The notch at the position where the support bar 16 is aligned with the push rod 9 facilitates the discharge of defective products.

[0047] like Figures 1-4 As shown, in this embodiment, guide grooves 6 are provided on both the corners of the placement plate 2 near the push rod 9 and the corners away from the push rod 9. The guide grooves 6 provide space for the placement plate 2 to rotate inside the conveying device 1, which facilitates the rotation of the placement plate 2. At the same time, the guide grooves 6 are provided at the diagonal corners of the placement plate 2 so that the placement plate 2 can only rotate around one direction, thus avoiding the situation where the placement plate 2 does not rotate in the predetermined direction.

[0048] The specific working method is as follows: Place the breast milk bags to be tested on the side wall of the placement plate 2. Since the connecting rope 3 connects multiple placement plates 2 together, and the placement plate 2 is fitted onto the side wall of the drive shaft on the conveying device 1, it is convenient to transport the breast milk bags on the top of the placement plate 2. By sending the breast milk bags to the bottom of the detection device 5, it is convenient for the detection device 5 to inspect the breast milk bags. When the detection device 5 detects that the breast milk bags are defective, the extension end of the impact hydraulic rod 7 is extended, causing the push rod 9 to impact the side wall of the placement plate 2. The placement plate 2 will then rotate around the connecting rope 3. The breast milk bags placed on the top of the placement plate 2 fall into the inside of the storage box 15 as the placement plate 2 flips, making it convenient to collect and process the defective products.

[0049] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
