Description

Technical Field

[0001] This utility model relates to the field of beef fattening technology, and more specifically, to a beef fattening quantitative packaging machine. Background Technology

[0002] Fatty beef is a type of beef product produced through a specific fattening process. Its characteristics include the even distribution of fat between muscle fibers, forming a marbled pattern. The meat is tender and juicy, and its even fat distribution makes it tender, juicy, and flavorful. It is suitable for various cooking methods such as hot pot and barbecue, satisfying both nutritional and delicious needs.

[0003] In the packaging stage of beef, the beef needs to be cut into slices or chunks of a specific weight. After being weighed by an electronic scale, the product can be packaged. Current packaging machines usually transport the packaging material to the sealing position, cover the surface of the container receiving the beef, and then use a heat sealing device to heat up to the set temperature and briefly press the film to the edge of the container, so that the surface of the material melts, further sealing the packaging box and container, isolating air and moisture to complete the seal.

[0004] In actual use, the heat sealing mechanism of the packaging machine presses the packaging box downwards. Since the packaging box is made of plastic, its physical properties change significantly when subjected to the high temperature of the heat sealing mechanism, causing the plastic to gradually soften. Under these circumstances, when the heat sealing mechanism continues to apply pressure to seal, the softened plastic packaging box is easily deformed. This deformation not only affects the appearance quality of the product, causing dents or twists on the surface of the packaging box, but more seriously, it may damage the sealing integrity of the packaging. Therefore, it needs to be improved and optimized. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a quantitative packaging machine for beef, which has the advantages of good packaging effect and prevention of deformation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a beef quantitative packaging machine, including a conveyor, a conveying roller is provided on the top of the conveyor, a packaging box is placed on the conveying roller, and a limiting chamber is fixedly installed inside the housing of the conveyor;

[0007] The limiting chamber has two sets of limiting grooves on its top left and right sides. Sliding blocks are slidably installed on both sides inside the limiting chamber. Two sets of connecting rods are fixedly installed on the top of each set of sliding blocks. The connecting rods on both sides first pass through the limiting grooves to the outside of the limiting chamber, and then extend upwards above the conveying rollers through the gaps between them. Limiting blocks are fixedly installed on the top of the two sets of connecting rods on both sides of the packaging box. Support grooves are present on the side of each set of limiting blocks facing the packaging box, and these support grooves fit snugly against the sealing edge of the packaging box.

[0008] As a preferred embodiment of this utility model, one end of each of the two sets of hinge rods is hinged to an eccentric position on the left and right sides of the rotating disk, and the other end of each of the two sets of hinge rods is hinged to the center position at the bottom of the slider.

[0009] As a preferred embodiment of this utility model, a sealing machine is provided on the top of the conveyor, and columns are fixedly installed at the four corners of the bottom of the sealing machine, with a base fixedly installed at the bottom of each column.

[0010] As a preferred embodiment of this utility model, guide columns are fixedly installed on both the left and right sides of the sealing machine, and a heat sealing head is fixedly installed on the telescopic end of the sealing machine, with the heat sealing head and the guide columns being movably connected.

[0011] As a preferred technical solution of this utility model, the sealing machine is provided with dust removal mechanisms at both the left and right ends. The dust removal mechanism includes a fixed block fixedly installed on the column, a movable block at the bottom of the fixed block, and a locking block fixedly installed at the top of the movable block. The movable block and the fixed block are interlocked by the locking block and the fixed block.

[0012] As a preferred technical solution of this utility model, the fixed block is internally threaded with a hand-tightening bolt, one end of which penetrates into the interior of the movable block, and a dust-sticking roller is rotatably installed between the two sets of movable blocks.

[0013] As a preferred technical solution of this utility model, a guide groove is provided on one side of the fixed block, and a movable block is slidably installed inside each set of guide grooves. The movable block and the guide groove are elastically connected by a spring, and a pressure roller is rotatably installed between the two sets of movable blocks.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model uses a worm gear to drive the worm wheel to rotate, which further causes the rotating disk to pull the two sets of sliders inward synchronously through the hinge rod.

Detailed Implementation

[0025] 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.

[0026] like Figures 1 to 7 As shown, this utility model provides a quantitative packaging machine for beef, including a conveyor 1, a conveyor roller 101 is provided on the top of the conveyor 1, a packaging box 102 is placed on the conveyor roller 101, and a limiting chamber 2 is fixedly installed inside the shell of the conveyor 1.

[0027] Two sets of limiting grooves 201 are provided on the top left and right sides of the limiting chamber 2. Sliding sliders 205 are slidably installed on the left and right sides inside the limiting chamber 2. Two sets of connecting rods 203 are fixedly installed on the top of each set of sliding sliders 205. The connecting rods 203 on the left and right sides first pass through the limiting grooves 201 to the outside of the limiting chamber 2. Then, the top of the connecting rods 203 extends upward through the gap between the conveying rollers 101 to the top of the conveying rollers 101. Limiting blocks 202 are fixedly installed on the top of the two sets of connecting rods 203. The limiting blocks 202 are located on both sides of the packaging box 102, and the two sets of limiting blocks 202 face the... One side of the packaging box 102 has a support groove 204, which fits into the sealing edge of the packaging box 102. A rotating disk 206 is rotatably installed inside the limiting chamber 2. Two sets of hinge rods 207 are hinged to the bottom of the rotating disk 206. The other end of the hinge rods 207 is hinged to two sets of sliders 205 respectively. A worm gear 208 is fixedly installed at the bottom of the rotating disk 206. A worm 209 is rotatably installed inside the limiting chamber 2. The worm 209 and the worm gear 208 are connected by a transmission. A motor 210 is fixedly installed on the outer wall of the limiting chamber 2. The output shaft of the motor 210 is fixedly connected to the worm 209.

[0028] One end of each of the two sets of hinge rods 207 is hinged to the eccentric position on the left and right sides of the rotating disk 206, and the other end of each set of hinge rods 207 is hinged to the center position at the bottom of the slider 205.

[0029] The conveyor 1 is equipped with a sealing machine 3 at its top. Each of the four corners of the sealing machine 3 has a fixed column 304, and each column 304 has a fixed base 301. Guide columns 302 are fixedly installed on both the left and right sides of the sealing machine 3. A heat sealing head 303 is fixedly installed at the bottom of a telescopic rod inside the sealing machine 3, and the heat sealing head 303 and the guide columns 302 are movably connected. During heat sealing, the heat sealing head 303 moves along the guide columns 302, ensuring its stability.

[0030] When it is necessary to package the beef, the staff weighs it using an electronic scale at the front of the production line, places the weighed beef into the packaging box 102, and then the packaging box 102 is conveyed and packaged by the conveyor roller 101 on the conveyor 1. When the packaging box 102 is conveyed to the bottom of the sealing machine 3, the staff can turn on the motor 210 through the main control switch. The operation of the motor 210 drives the worm gear 209 to rotate, and the worm gear 209 further drives the worm wheel 208 to rotate. The rotation of the worm wheel 208 will drive the rotating disk 206 to rotate slowly. The rotation of 06 will cause the two sets of hinge rods 207 to move, and the two sets of hinge rods 207 will further pull the two sets of sliders 205 inward. Finally, the two sets of limit blocks 202 will move inward synchronously along the limit groove 201 to fix the packaging box 102. Through the setting of the support groove 204 on one side of the limit block 202, the limit block 202 limits and supports the packaging box 102 at the same time. At this time, the operation of the sealing machine 3 will drive the heat sealing head 303 to move downward along the guide column 302, and finally heat seal the plastic film on the top of the packaging box 102 to realize the packaging operation.

[0031] The worm gear 209 drives the worm wheel 208 to rotate, which in turn causes the rotating disk 206 to pull the two sets of sliders 205 inward synchronously via the hinge rod 207. Finally, the two sets of limit blocks 202 limit and support the packaging box 102. Compared with traditional devices, this device can not only ensure the stability of the packaging box 102 during packaging and prevent the heat sealing head 303 from damaging the packaging box 102, but also ensure that the packaging box 102 is located in the middle of the conveyor 1 and aligned with the heat sealing head 303 through the synchronous displacement of the two sets of limit blocks 202, thus improving the packaging accuracy.

[0032] The sealing machine 3 is equipped with dust removal mechanisms 4 at both ends. The dust removal mechanism 4 includes a fixed block 401 fixedly installed on the column 304, a movable block 402 at the bottom of the fixed block 401, and a locking block 405 fixedly installed at the top of the movable block 402. The movable block 402 and the fixed block 401 are interlocked by the locking block 405.

[0033] The fixed block 401 has a threaded internal thread fitted with a hand-tightening bolt 406, one end of which extends into the interior of the movable block 402. A dust-adhesive roller 404 is rotatably mounted between the two sets of movable blocks 402. The hand-tightening bolt 406 is used to fix the movable block 402, and the dust-adhesive roller 404 is used to absorb and remove dust from the plastic film. Without the hand-tightening bolt 406, the fixed block 401 can be engaged with the fixed block 401 using a locking block 405.

[0034] The fixed block 401 has a guide groove 407 on one side. A movable block 408 is slidably installed inside each set of guide grooves 407. The movable block 408 and the guide groove 407 are elastically connected by a spring 409. A pressure roller 403 is rotatably installed between the two sets of movable blocks 408.

[0035] When packaging the beef, the plastic packaging film passes from the left side to the right side of the sealing machine 3, and is located between the packaging box 102 and the heat sealing head 303. When the heat sealing head 303 presses down, it heat seals the packaging film onto the packaging box 102, thus achieving packaging. As the packaging film is conveyed, the pressure roller 403 will move downward through the elastic potential energy of the spring 409, ensuring that the packaging film and the dust-adhesive roller 404 adhere to each other. Furthermore, the dust-adhesive roller 404 will absorb the dust on the packaging film. When the dust-adhesive roller 404 needs to be replaced, the operator rotates the hand-tightening bolt 406 to move the hand-tightening bolt 406 away from the inside of the movable block 402, so that the operator can remove the dust-adhesive roller 404 together with the movable block 402 for replacement.

[0036] The pressure roller 403 ensures that the packaging film and the dust-adhesive roller 404 come into contact with each other. The dust-adhesive roller 404 removes the dust adhering to the bottom of the packaging film during conveying, preventing dust from being sealed inside the packaging box 102. Compared with traditional devices, this device can ensure the cleanliness of the packaging film, avoid quality problems of the beef after heat sealing, and ensure product quality and food safety.

[0037] Working principle and usage process of this utility model:

[0038] When it is necessary to package the beef, the workers weigh it using an electronic scale at the front of the production line, place the weighed beef into the packaging box 102, and then transport and package it using the conveyor rollers 101 on the conveyor 1. The conveying operation is stopped during heat pressing, and the conveying speed and start / stop control are all set by the existing control system. When the packaging box 102 is transported to the bottom of the sealing machine 3, the workers can turn on the motor 210 via the master switch. The operation of the motor 210 drives the worm gear 209 to rotate, which in turn drives the worm wheel 208 to rotate. The rotation of the worm wheel 208 causes the rotating disk 206 to rotate slowly, and the rotation of the rotating disk 206 drives the two sets of hinged rods. The displacement of 207, the two sets of hinge rods 207 further pull the two sets of sliders 205 inward, and finally the two sets of limiting blocks 202 move inward synchronously along the limiting groove 201 to fix the packaging box 102. Through the setting of the support groove 204 on one side of the limiting block 202, the limiting block 202 limits and supports the packaging box 102 at the same time. At this time, the operation of the sealing machine 3 will drive the heat sealing head 303 to move downward along the guide post 302, and finally heat seal the plastic film on the top of the packaging box 102 to realize the packaging operation. After the packaging is completed, the limiting block 202 moves in the opposite direction under the reverse rotation of the rotating disk 206, and the two sets of sliders 205 move in opposite directions, thereby driving the limiting block 202 to move together, and thus releasing the fixing of the packaging box 102.
