Description

Technical Field

[0001] This utility model relates to the technical field of meat product testing, and in particular to a meat product additive testing device. Background Technology

[0002] Meat products need to be tested for additives before being sold on the market to ensure food safety. An additive testing device is required to sample the meat products. Existing technology, Chinese utility model patent CN217237269U, discloses a device for testing additives in quick-frozen meat products. This device places a sampling cylinder against the quick-frozen meat to be sampled. A drive unit rotates the sampling cylinder, causing the serrated teeth on the cylinder to rotate and cut through the meat. After cutting through the meat, the rotation of the sampling cylinder stops, and a pushing component pushes out the meat column inside the sampling cylinder to facilitate sampling. Different parts of the quick-frozen meat can be sampled as needed. When it is necessary to remove the sample from the sampling cylinder, the screw is rotated, moving it towards the mounting box. The screw drives a push plate, which pushes out the sample from the sampling cylinder, allowing for sample removal.

[0003] However, the cylindrical sampling tube of the above-mentioned detection device has a large rigidity. When sampling, due to the high hardness of frozen meat products, the sample will fill the sampling tube. At this time, the sampling tube cannot expand further to increase its inner diameter, making it difficult to push the sample out, resulting in sampling difficulties and reduced work efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a meat product additive detection device that uses an expandable sampling cylinder to increase the internal area, thereby reducing the resistance to the sample, facilitating efficient sample removal, and improving work efficiency.

[0005] This utility model discloses a meat product additive detection device, comprising an outer cylinder and a sampling cylinder. The sampling cylinder is located at the lower end of the inner cavity of the outer cylinder, and a cutting edge is provided at the lower edge of the sampling cylinder. It also includes an upper retaining ring, a push rod, a push plate, a threaded sleeve, a handwheel, a drive component, and a threaded assembly. The sampling cylinder has a regular polygonal cross-section and is made of a highly elastic material. The threaded sleeve is rotatably mounted on the inner wall of the outer cylinder, and an internal thread is provided on the inner wall of the threaded sleeve. The handwheel is concentrically mounted inside the upper end of the threaded sleeve, and the side of the handwheel extends outward from the upper end of the outer cylinder. The upper retaining ring is concentrically mounted... The upper end of the sampling cylinder is installed inside the upper end of the threaded sleeve. The upper end of the push rod is rotatably connected to the center of the upper retaining ring. A push plate is installed at the lower end of the push rod, located inside the sampling cylinder and at the lower end of the outer cylinder. A threaded assembly is installed at the upper end of the sampling cylinder, which is threadedly connected to the internal thread of the threaded sleeve. The threaded assembly can retract inward to disengage from the internal thread of the threaded sleeve. A drive component is installed between the upper retaining ring and the sampling cylinder, driving the sampling cylinder to descend and extend beyond the lower end of the outer cylinder. The wall thickness of the sampling cylinder is set to be within 0.5 mm, and it is designed to have radially... The sampler is elastic yet rigid in the axial direction. During sampling for meat product additive testing, the sampling tube retracts inside the outer cylinder, pressing the lower end of the outer cylinder against the meat product. This causes the threaded assembly to retract inward and disengage from the internal thread of the threaded sleeve. At this point, the drive unit pushes the sampling tube towards the lower end of the outer cylinder, allowing the cutting edge of the sampling tube to penetrate the meat product and cut it, leaving a sample inside the sampling tube. Pulling the sampling tube out of the meat product causes the threaded assembly to move outward and connect with the internal thread of the threaded sleeve. One hand holds the outer cylinder. With the other hand, turn the handwheel, which drives the threaded sleeve to rotate. Under the action of the internal thread and the threaded assembly, the sampling cylinder contracts into the threaded sleeve and the outer cylinder. Since the relative position of the push plate with the outer cylinder remains unchanged under the support of the push rod and the upper retaining ring, the meat product sample is pushed out by the push plate. During the pushing process, the side wall of the sampling cylinder expands outward under the pressure of the sample, and its cross-section tends to become more circular from a regular polygon. The increase in inner diameter and internal area makes the resistance to the sample smaller, which facilitates the efficient removal of the sample and improves work efficiency.

[0006] Preferably, the cutting edge of the sampling tube is a single blade, and the cutting edge is set on the outer wall of the sampling tube. With the above setting, when the sampling tube cuts meat products, its cutting edge pushes outward the edge of the hole wall formed by the sampling and cutting of the meat products, so that the outer diameter of the meat product sample is not greater than the inner diameter of the sampling tube, reducing the pressure of the sample inside the sampling tube on its inner wall, and further improving the sample extraction efficiency.

[0007] Preferably, the threaded assembly includes a seat ring, multiple threaded blocks, and multiple springs. The seat ring is concentrically mounted on the upper end of the sampling cylinder. The multiple threaded blocks are circumferentially and evenly slidably mounted on the seat ring, and each threaded block slides radially along the seat ring. Damping is provided between the multiple threaded blocks and the seat ring. The outer walls of the multiple threaded blocks are provided with external threads that match the internal threads of the threaded sleeve. The outer ends of the multiple springs are respectively connected to the multiple threaded blocks, and the inner ends of the multiple springs are connected to the seat ring. The elastic force of the multiple springs presses the multiple threaded blocks against the inner wall of the threaded sleeve, so that the external threads of the multiple threaded blocks are threadedly connected to the internal threads of the threaded sleeve. At this time, rotating the handwheel and the threaded sleeve can drive the sampling cylinder to rise and fall, and slide the multiple threaded blocks inward, so that the external threads of the multiple threaded blocks are disengaged from the internal threads of the threaded sleeve. At this time, the sampling cylinder can be pushed downward under the action of the driving component. The structure is simple and practical.

[0008] Preferably, it also includes multiple limiting grooves and multiple limiting sliders. Multiple vertical limiting grooves are evenly arranged on the inner upper circumference of the threaded sleeve, and multiple limiting sliders are arranged on the outer wall of the seat ring. The multiple limiting sliders are slidably connected to the multiple limiting grooves respectively. The multiple limiting sliders slide in the multiple limiting grooves respectively to limit the lifting and lowering of the seat ring and the sampling cylinder, thereby improving the stability of the lifting and lowering of the sampling cylinder.

[0009] Preferably, the device further includes a drive ring, multiple connecting rods, and multiple levers. The drive ring is concentrically mounted on a handwheel. The inner ends of the multiple connecting rods are rotatably connected to the drive ring, and the inner ends of the multiple connecting rods are rotatably connected to multiple slider seats. The multiple slider seats are slidably mounted on an upper retaining ring and are evenly arranged circumferentially. Each slider seat slides radially along the upper retaining ring. Levers are mounted on the lower ends of each slider seat. Slots are provided on each of the multiple threaded blocks, and the slots of the multiple threaded blocks are matched and aligned with the multiple levers. When the sampling cylinder and the seat ring rise close to the upper retaining ring, the lower ends of the multiple levers are inserted into the slots of the multiple threaded blocks. Rotating the drive ring causes the outer ends of the multiple connecting rods to rotate, causing the multiple connecting rods to tend to be radially parallel to the upper retaining ring. This causes the multiple connecting rods to push the multiple slider seats and multiple levers inward, and the multiple levers to push the multiple threaded blocks inward, causing the multiple threaded blocks to disengage from the internal threads of the threaded sleeve, thereby releasing the sampling cylinder. The operation is simple and practical.

[0010] Preferably, the driving component includes a second spring, which is sleeved on the outside of the top rod. The upper end of the second spring is connected to the upper retaining ring, and the lower end of the second spring is connected to the seat ring. When the seat ring rises and approaches the upper retaining ring, the second spring is compressed and stores force. When the multiple threaded blocks disengage from the internal thread of the threaded sleeve, the elastic force of the second spring is released, pushing the seat ring and the sampling cylinder downwards out of the outer cylinder, so that the sampling cylinder can be inserted into the meat product for sampling. The structure is simple and the cost is low.

[0011] Preferably, the driving component includes an electric push cylinder, the fixed end of which is installed on the lower end face of the upper retaining ring, and the push rod of the electric push rod is aligned with the seat ring; when the push rod of the electric push cylinder retracts, the seat ring and the sampling cylinder are retracted into the inner part of the outer cylinder through the cooperation of the threaded sleeve and the threaded assembly; when the push rod of the electric push cylinder extends, it pushes the seat ring and the sampling cylinder downward to push the outer cylinder, so that the sampling cylinder is inserted into the meat product for sampling. It has a large thrust and can sample frozen meat products with high hardness, making it practical.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The wall thickness of the sampling cylinder is set to within 0.5 mm, and it is made to be elastic in the radial direction and rigid in the axial direction. When sampling for meat product additive testing, the sampling cylinder retracts inside the outer cylinder, pressing the lower end of the outer cylinder against the meat product, causing the threaded assembly to retract inward and disengage from the internal thread of the threaded sleeve. At this time, the driving component pushes the sampling cylinder towards the lower end of the outer cylinder, allowing the sampling cylinder to be inserted into the meat product through the cutting edge, cutting the meat product to form a sample retained inside the sampling cylinder. The sampling cylinder is then pulled out of the meat product, causing the threaded assembly to... The outer cylinder is connected to the internal thread of the threaded sleeve. One hand holds the outer cylinder and the other hand turns the handwheel. The handwheel drives the threaded sleeve to rotate. Under the action of the internal thread and the threaded assembly, the sampling cylinder contracts into the threaded sleeve and the outer cylinder. Since the relative position of the push plate with the outer cylinder remains unchanged under the support of the push rod and the upper retaining ring, the meat product sample is pushed out by the push plate. During the pushing process, the side wall of the sampling cylinder expands outward under the pressure of the sample. Its cross-section tends to become more circular from a regular polygon. The increase in inner diameter and internal area makes the resistance to the sample smaller, which facilitates the efficient removal of the sample and improves work efficiency.

[0020] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0021] like Figures 1 to 4 As shown, a meat product additive detection device includes an outer cylinder 1 and a sampling cylinder 2. The sampling cylinder 2 is located at the lower end of the outer cylinder 1, and a cutting edge is provided at the lower edge of the sampling cylinder 2. It also includes an upper retaining ring 3, a push rod 4, a push plate 5, a threaded sleeve 6, a handwheel 7, a driving component, and a threaded assembly. The sampling cylinder 2 has a regular polygonal cross-section and is made of a highly elastic material. The threaded sleeve 6 is rotatably mounted on the inner wall of the outer cylinder 1, and an internal thread is provided on the inner wall of the threaded sleeve 6. The handwheel 7 is concentrically mounted inside the upper end of the threaded sleeve 6, and the side of the handwheel 7 extends outward from the upper end of the outer cylinder 1. The upper retaining ring 3 is concentrically mounted... The upper end of the push rod 4 is rotatably connected to the center of the upper retaining ring 3 inside the upper end of the threaded sleeve 6. The lower end of the push rod 4 is equipped with a push plate 5, which is located inside the sampling cylinder 2 and at the lower end of the outer cylinder 1. The upper end of the sampling cylinder 2 is equipped with a threaded assembly, which is threadedly connected to the internal thread of the threaded sleeve 6. The threaded assembly can retract inward to disengage from the internal thread of the threaded sleeve 6. The driving component is installed between the upper retaining ring 3 and the sampling cylinder 2. The driving component drives the sampling cylinder 2 to descend and extend out of the lower end of the outer cylinder 1. The cutting edge of the sampling cylinder 2 is a single blade, and the cutting surface is set on the outer side wall of the sampling cylinder 2.

[0022] The wall thickness of sampling cylinder 2 is set to within 0.5 mm, and it is made to be elastic in the radial direction and rigid in the axial direction. When sampling for meat product additive testing, sampling cylinder 2 retracts inside the outer cylinder 1, pressing the lower end of the outer cylinder 1 against the meat product, causing the threaded assembly to retract inward and disengage from the internal thread of the threaded sleeve 6. At this time, the driving component actuates to push sampling cylinder 2 towards the lower end of the outer cylinder 1, allowing the cutting edge of sampling cylinder 2 to be inserted into the meat product and cut the meat product to form a sample retained inside sampling cylinder 2. When sampling cylinder 2 cuts the meat product, its cutting edge pushes outward to push the edge of the hole wall formed by the sampling cut of the meat product, so that the outer diameter of the meat product sample is not greater than the inner diameter of sampling cylinder 2, reducing the impact of the sample inside sampling cylinder 2 on the meat product. The pressure on its inner wall pulls the sampling cylinder 2 out of the meat product, causing the threaded assembly to move outward and connect with the internal thread of the threaded sleeve 6. One hand holds the outer cylinder 1 and the other hand rotates the handwheel 7. The handwheel 7 drives the threaded sleeve 6 to rotate. Under the action of the internal thread and the threaded assembly, the sampling cylinder 2 contracts into the threaded sleeve 6 and the inner cylinder 1. Since the push plate 5 remains in a constant relative position with the outer cylinder 1 under the support of the top rod 4 and the upper retaining ring 3, the meat product sample is pushed out through the push plate 5. During the pushing process, the side wall of the sampling cylinder 2 expands outward under the pressure of the sample, and its cross-section tends to become more circular from a regular polygon. The increased inner diameter and internal area make the resistance to the sample smaller, making it easier to extract the sample efficiently and improving work efficiency. Example 2

[0023] like Figures 1 to 6As shown, based on Embodiment 1, the threaded assembly includes a seat ring 8, multiple threaded blocks 9, and multiple springs 10. The seat ring 8 is concentrically mounted on the upper end of the sampling cylinder 2. The multiple threaded blocks 9 are circumferentially and evenly slidably mounted on the seat ring 8, and all of the multiple threaded blocks 9 slide radially along the seat ring 8. Damping is provided between the multiple threaded blocks 9 and the seat ring 8. The outer walls of the multiple threaded blocks 9 are provided with external threads that match the internal threads of the threaded sleeve 6. The outer ends of the multiple springs 10 are respectively connected to the multiple threaded blocks 9, and the inner ends of the multiple springs 10 are respectively connected to the seat ring 8. It also includes multiple limiting grooves 11 and multiple limiting sliders 12. Multiple vertical limiting grooves 11 are evenly provided on the inner circumference of the threaded sleeve 6. Multiple limiting sliders 12 are provided on the outer wall of the seat ring 8, and the multiple limiting sliders 12 are respectively connected to the multiple limiting grooves 11. The sliding connection also includes a drive ring 13, multiple connecting rods 14, and multiple levers 16. The drive ring 13 is concentrically rotatably mounted on the handwheel 7. The inner ends of the multiple connecting rods 14 are rotatably connected to the drive ring 13. The inner ends of the multiple connecting rods 14 are rotatably connected to multiple slider seats 15 respectively. The multiple slider seats 15 are slidably mounted on the upper retaining ring 3. The multiple slider seats 15 are evenly arranged circumferentially. The multiple slider seats 15 slide radially along the upper retaining ring 3. The lower ends of the multiple slider seats 15 are all equipped with levers 16. The multiple threaded blocks 9 are all provided with slots. The slots of the multiple threaded blocks 9 are respectively matched and aligned with the multiple levers 16. The driving component includes a second spring 17. The second spring 17 is sleeved on the outside of the top rod 4. The upper end of the second spring 17 is connected to the upper retaining ring 3, and the lower end of the second spring 17 is connected to the seat ring 8.

[0024] Multiple limiting sliders 12 slide in multiple limiting grooves 11 to limit the lifting and lowering of the seat ring 8 and the sampling cylinder 2, thereby improving the stability of the lifting and lowering of the sampling cylinder 2. The elastic force of multiple springs 10 presses multiple threaded blocks 9 against the inner wall of the threaded sleeve 6, so that the external threads of the multiple threaded blocks 9 are threadedly connected to the internal threads of the threaded sleeve 6. At this time, turning the handwheel 7 and the threaded sleeve 6 can drive the sampling cylinder 2 to lift and lower. When the sampling cylinder 2 and the seat ring 8 rise and approach the upper retaining ring 3, the second spring 17 is compressed and stores force, and the lower ends of multiple levers 16 are respectively inserted into the slots of multiple threaded blocks 9. Rotating the drive ring 13 causes the outer ends of multiple connecting rods 14 to rotate, making the multiple connecting rods 14 tend to be radially parallel to the upper retaining ring 3. This causes the multiple connecting rods 14 to push multiple slider seats 15 and multiple lever plates 16 inward, which in turn push multiple threaded blocks 9 inward. This causes the multiple threaded blocks 9 to disengage from the internal threads of the threaded sleeve 6, thereby releasing the sampling cylinder 2. The release of the elastic force of the second spring 17 pushes the seat ring 8 and the sampling cylinder 2 downward out of the outer cylinder 1, allowing the sampling cylinder 2 to be inserted into the meat product for sampling. The structure is simple and the cost is low. Example 3

[0025] Based on Example 2, the driving component is replaced with an electric push cylinder. The fixed end of the electric push cylinder is installed on the lower end face of the upper retaining ring 3, and the push rod of the electric push rod is aligned with the seat ring 8. When the push rod of the electric push cylinder retracts, the seat ring 8 and the sampling cylinder 2 are retracted into the inner cavity of the outer cylinder 1 through the cooperation of the threaded sleeve 6 and multiple threaded blocks 9. When the push rod of the electric push cylinder extends, it pushes the seat ring 8 and the sampling cylinder 2 downward to push the outer cylinder 1, so that the sampling cylinder 2 is inserted into the meat product for sampling. The thrust is large, which can sample frozen meat products with high hardness.

[0026] like Figures 1 to 6 As shown, this utility model discloses a meat product additive detection device. During operation, when sampling for meat product additive detection, the sampling cylinder 2 retracts inside the outer cylinder 1, pressing the lower end of the outer cylinder 1 against the meat product. Then, the drive ring 13 rotates, causing the outer ends of multiple connecting rods 14 to rotate, making the connecting rods 14 radially parallel to the upper retaining ring 3. This causes the connecting rods 14 to push multiple slider seats 15 and multiple levers 16 inwards, which in turn push multiple threaded blocks 9 inwards, disengaging the threaded blocks 9 from the internal threads of the threaded sleeve 6, thus releasing the sampling cylinder 2. Then, the drive component pushes the sampling cylinder 2 towards the lower end of the outer cylinder 1, allowing the sampling cylinder 2 to be inserted into the meat product through its cutting edge, cutting the meat product to form a sample which is retained in the sampling cylinder. Inside sample cylinder 2, the sampling cylinder 2 is pulled out of the meat product. The elastic force of multiple springs 10 presses multiple threaded blocks 9 against the inner wall of the threaded sleeve 6, so that the external threads of the multiple threaded blocks 9 are threadedly connected to the internal threads of the threaded sleeve 6. Finally, the outer cylinder 1 is held with one hand and the handwheel 7 is turned with the other hand. The handwheel 7 drives the threaded sleeve 6 to rotate. Under the action of the internal threads and the external threads of the multiple threaded blocks 9, the sampling cylinder 2 contracts into the threaded sleeve 6 and the outer cylinder 1. Since the push plate 5 remains in a constant relative position with the outer cylinder 1 under the support of the top rod 4 and the upper retaining ring 3, the meat product sample is pushed out by the push plate 5. During the pushing process, the side wall of the sampling cylinder 2 expands outward under the pressure of the sample. Its cross-section tends to become more circular from a regular polygon. The increased inner diameter and internal area make the resistance to the sample smaller, which facilitates the efficient removal of the sample.

[0027] The main functions achieved by this utility model are:

[0028] 1. The sampling tube, which can expand to increase its internal area, reduces the resistance to the sample, making it easier to extract the sample efficiently and improving work efficiency.

[0029] 2. It allows for fully manual sampling, reducing usage costs;

[0030] 3. It can perform electric sampling and is suitable for frozen meat products with high hardness.

[0031] The meat product additive detection device of this utility model has common mechanical installation, connection or setting methods, and can be implemented as long as it can achieve its beneficial effect. The outer cylinder 1, sampling cylinder 2, top rod 4, push plate 5, threaded sleeve 6, handwheel 7, threaded block 9, spring 10, drive ring 13, spring 2 17 and electric push cylinder of this meat product additive detection device are purchased from the market. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual, without requiring any creative work from technical personnel in this field.
