Description

A sealing device for meat packaging Technical Field

[0001] This utility model relates to the field of meat packaging technology, and more specifically, to a sealing device for meat packaging. Background Technology

[0002] The main purpose of meat packaging is to address issues such as preventing external contaminants, inhibiting microbial growth, and maintaining the color and texture of the meat. After undergoing a series of processing steps, cured meat needs to be packaged to prevent contamination, oxidation, and microbial damage during storage and transportation, thereby preserving its original flavor, color, and texture. Therefore, cured meat requires sealed packaging.

[0003] Most common sealed packaging products have poor sealing effects and limited sealing functionality. During the sealing process, the sealing stability is poor, and the sealing process is cumbersome, resulting in high labor costs and affecting sealing efficiency.

[0004] For example, Chinese patent CN220076864U discloses a sealing device for cured meat packaging, including a base plate, a support plate fixedly connected to the upper surface of the base plate, a limiting plate fixedly connected to the upper surface of the support plate, and a through hole formed on the upper surface of the limiting plate. Although this device can seal cured meat, its function is relatively cumbersome; moreover, the sealing performance and sealing environment are poor, affecting the quality of the cured meat and the efficiency of product production.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0006] In view of the problems in the related technologies, this utility model proposes a sealing device for meat packaging to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] A sealing device for meat packaging includes a mounting frame, mounting blocks symmetrically arranged on both sides of the top of the mounting frame, a gantry frame at the top of the mounting blocks, and a pressing mechanism interspersed in the middle of the gantry frame; a spring material assembly is arranged inside the top of the mounting frame, and two sets of sealing mechanisms are arranged on the spring material assembly; a placement plate is arranged on the inner side of the bottom of the mounting frame, and two sets of sealing mechanisms are arranged on one side of the top of the placement plate.

[0009] Furthermore, to improve sealing performance and the tightness of the product seal, thereby enhancing product quality, the pressing mechanism includes a connecting shaft located in the middle of the gantry frame. A circular locking post is located at the bottom of the connecting shaft, and a movable plate is engaged with the outer side of the circular locking post. Several elastic springs are located at the bottom of the movable plate, and a rubber pad is placed at the bottom of each elastic spring. A rubber pad cloth is placed at the bottom of the rubber pad. Movable columns penetrating the gantry frame are located on both sides of the connecting shaft. The bottom end of each movable column is fixedly connected to the top of the movable plate, and a connecting plate is connected to the top of the movable column. A groove is formed in the middle of the connecting plate. A hydraulic cylinder is connected to the top of the connecting shaft through the gantry frame, and the groove mates with the hydraulic cylinder. The four corners of the rubber pad cloth are bolted to the four corners of the rubber pad.

[0010] Furthermore, in order to improve the efficiency of sealing production and the convenience of the device, the spring assembly includes several return springs set inside the top of the mounting frame. The return springs are equipped with telescopic columns inside, and a return plate is set at the top of the return springs.

[0011] Furthermore, in order to improve the sealing performance and enhance the quality of the product, the pressure sealing mechanism includes two sets of pressure sealing grooves opened on the reset plate. A drive shaft is set inside the pressure sealing groove, and an arc-shaped heat sealing plate is sleeved on the outer circumference of the drive shaft. One end of the drive shaft is connected to a drive motor, and an air extraction groove is opened on the arc-shaped heat sealing plate.

[0012] Furthermore, to enhance the reliability of the seal and preserve the texture of the cured meat, the sealing mechanism includes two sets of vacuum pumps mounted on the placement plate. Each set of vacuum pumps has an extraction pipe at its top, and an extraction head is connected to the top of the extraction pipe. A screen is installed inside the extraction head. A mounting groove that mates with the extraction head is provided on one side of the top of the mounting frame.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. When the cured meat completes a series of processing steps and is then packaged, a sealing device is used to seal it. This process involves a pressing mechanism, a spring-loaded assembly, and a sealing mechanism. After processing, the pressing and sealing mechanisms work together. When the pressing mechanism applies downward pressure, the sealing mechanism on the top mounting frame performs initial sealing and air extraction. When the pressure reaches the bottom of the spring-loaded assembly, the bottom sealing mechanism performs final sealing and air extraction, improving sealing performance and the tightness of the seal, enhancing sealing reliability, improving product quality, and preserving the flavor of the cured meat. Finally, a heat-sealing mechanism is used to further enhance sealing performance. After sealing, the pressing mechanism rises, the spring-loaded assembly resets, and the sealed cured meat rises upwards for easy manual removal, improving the convenience of the device and increasing the efficiency of the sealing process.

[0015] 2. By incorporating a pressing mechanism, the elastic spring, rubber pad, and rubber mat allow for pressure release of the cured meat. The rubber pad and rubber mat conform to the shape of the cured meat during pressing, and when the elastic spring contracts, the rubber pad and rubber mat adhere to the vacuum bag containing the cured meat. This, combined with the sealing mechanism, achieves a vacuum seal, improving sealing performance and the tightness of the product seal, thus enhancing product quality.

[0016] 3. By setting up a sealing mechanism, the air extraction head at the top of the mounting frame performs an initial vacuuming of the cured meat inside the vacuum bag. Then, when the pressing mechanism squeezes down, the air extraction head at the bottom performs a second vacuuming, which enhances the reliability of the seal and preserves the taste of the cured meat.

[0017] 4. By setting up a spring assembly, when the pressing mechanism presses down, it holds the return spring. Then, when the pressing mechanism rises, it resets the vacuum-sealed cured meat on the return plate, which can then be manually removed, thus improving the efficiency of sealing production and the convenience of the device.

[0018] 5. By setting up a pressure sealing mechanism, the position of the arc-shaped heat sealing plate is adjusted by the drive motor. In conjunction with the sealing mechanism, the air in the vacuum bag is removed through the air extraction groove, and then the arc-shaped heat sealing plate is heated and sealed through electrical connection, thereby improving the sealing performance and enhancing the quality of the product.

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0029] According to an embodiment of the present invention, a sealing device for meat packaging is provided.

[0030] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. As shown in Figures 1-6, a sealing device for meat packaging according to an embodiment of the present invention includes a mounting frame 1. The mounting frame 1 is characterized in that mounting blocks 2 are symmetrically arranged on both sides of the top of the mounting frame 1, a gantry frame 3 is arranged at the top of the mounting blocks 2, and a pressing mechanism 4 is inserted through the middle of the gantry frame 3; a spring material assembly 5 is arranged inside the top of the mounting frame 1, and two sets of sealing mechanisms 6 are arranged on the spring material assembly 5; a placement plate 7 is arranged on the inner side of the bottom of the mounting frame 1, and two sets of sealing mechanisms 8 are arranged on one side of the top of the placement plate 7.

[0031] With the help of the above-mentioned technical solution of this utility model, when the cured meat completes a series of processing steps and is then packaged, a sealing device is used to seal the cured meat. The sealing process involves a pressing mechanism 4, a spring material assembly 5, and a sealing mechanism 8. After the cured meat is processed, the pressing mechanism 4 and the sealing mechanism 8 work together. When the pressing mechanism 4 begins to apply downward pressure, the sealing mechanism 8 on the top mounting frame 1 performs initial sealing and air extraction. When the pressure of the pressing mechanism 4 reaches the bottom of the spring material assembly 5, the bottom sealing mechanism 8 performs final sealing and air extraction, improving the sealing performance and the tightness of the product seal. This also enhances the reliability of the seal, improves product quality, and preserves the taste of the cured meat. Finally, a heat-sealing mechanism 6 is used to further improve the sealing performance. After the cured meat is sealed, the pressing mechanism 4 rises, the spring material assembly 5 resets, and the sealed cured meat rises upwards for easy manual removal, improving the convenience of the device and increasing the efficiency of the sealing production process.

[0032] In one embodiment, the pressing mechanism 4 includes a connecting shaft 401 located in the middle of the gantry frame 3. A circular locking post 402 is located at the bottom of the connecting shaft 401. A movable plate 403 is engaged with the outer side of the circular locking post 402. Several elastic springs 404 are located at the bottom of the movable plate 403, and a rubber pad 405 is commonly located at the bottom of each elastic spring 404. A rubber pad cloth 406 is located at the bottom of the rubber pad 405. Movable columns 407 penetrating the gantry frame 3 are located on both sides of the connecting shaft 401. The bottom end of the movable column 407 is fixedly connected to the top of the movable plate 403, and a connecting plate 408 is connected to the top of the movable column 407. A groove 409 is formed in the middle of the connecting plate 408. A hydraulic cylinder 410 is connected to the top of the connecting shaft 401 through the gantry frame 3, and the groove 409 cooperates with the hydraulic cylinder 410. The four corners of the rubber pad cloth 406 are bolted to the four corners of the rubber pad 405, thereby improving the sealing performance and the tightness of the product seal, and improving product quality.

[0033] In one embodiment, the above-mentioned spring assembly 5 includes a plurality of return springs 501 disposed inside the top of the mounting frame 1. The return springs 501 are provided with telescopic columns 502 inside, and the top of the return springs 501 are all provided with a return plate 503, thereby improving the efficiency of sealing production and the convenience of the device.

[0034] The working principle of the pressing mechanism 4 and the spring material assembly 5 is as follows: After the cured meat is placed into the vacuum bag, it is placed on the reset plate 503. The hydraulic cylinder 410 is activated to drive the connecting shaft 401 to move downward. The circular locking post 402 at the bottom of the connecting shaft 401 is engaged with and fixed the movable plate 403. The bottom of the movable plate is connected to a rubber pad 405 through an elastic spring 404. After the four corners of the rubber pad cloth 406 on the rubber pad 405 are fixed by bolts, the connecting shaft 401 drives the rubber pad 405 to press and seal the cured meat in the vacuum bag on the reset plate 503. The movable column 407 is stabilized on the gantry 3 and moves vertically. The groove of the connecting plate 408 is larger than the width of the hydraulic cylinder 410. The hydraulic cylinder 410 is activated to drive the connecting shaft 401 to move upward. Then the reset spring 501 and the telescopic column 502 are reset. Then the sealed cured meat is reset upward for easy removal.

[0035] In one embodiment, the sealing mechanism 6 includes two sets of sealing grooves 601 formed on the reset plate 503. A drive shaft 602 is provided inside the sealing groove 601, and an arc-shaped heat sealing plate 603 is sleeved on the outer circumference of the drive shaft 602. One end of the drive shaft 602 is connected to a drive motor 604, and an air extraction groove 605 is formed on the arc-shaped heat sealing plate 603, thereby improving the sealing performance and enhancing the quality of the product.

[0036] Working principle of sealing mechanism 6: When the vacuum bag of cured meat is placed on the upper air extraction groove 605 of the arc heat sealing plate 603, the drive motor 604 is started to rotate the arc heat sealing plate 603 on the drive shaft 602 to press one end of the vacuum bag. After the sealing mechanism 8 has extracted the air from the space of the air extraction groove 605, it uses the arc heat sealing plate 603 to heat and seal the vacuum bag by means of electrical connection.

[0037] In one embodiment, the sealing mechanism 8 includes two sets of vacuum pumps 801 mounted on the placement plate 7. Each set of vacuum pumps 801 has a suction pipe 802 at its top, and a suction head 803 is connected to the top of each suction pipe 802. A screen 804 is installed inside the suction head 803. A mounting groove 9, which mates with the suction head 803, is provided on one side of the top of the mounting bracket 1.

[0038] The working principle of the sealing mechanism 8: When the cured meat in the vacuum bag is pressed by the pressing mechanism 4, two sets of vacuum pumps 801 set on the placement plate 7 perform vacuuming. The vacuum pump 801 has a vacuum pipe 802 connected to a vacuum head 803, and both vacuum heads 803 are installed on the mounting slot 9 of the mounting frame 1. The vacuum head 803 at the top of the mounting frame 1 performs a preliminary vacuum seal on the cured meat inside the vacuum bag. Then, when the pressing mechanism 4 presses down again, the vacuum head 803 at the bottom performs a second vacuuming to complete the sealing. Impurities generated during vacuuming are blocked from entering by the screen 804.

[0039] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0040] In practical applications, after the cured meat has undergone a series of processing steps and is then packaged, it is placed into a vacuum bag. The vacuum bag is then placed on the reset plate 503 of the spring material assembly 5. The connecting shaft 401 on the pressing mechanism 4 drives the rubber pad 405 to press and seal the cured meat in the vacuum bag on the reset plate 503. Meanwhile, the reset spring 501 and the telescopic column 502 of the spring material assembly 5 extend and retract downwards. Then, in conjunction with the air extraction heads 803 at the top and bottom of the sealing mechanism 8, the cured meat in the vacuum bag is sealed (the working principle of the sealing mechanism 8 is as described above). Then, when the hydraulic cylinder 410 drives the connecting shaft 401 to move upwards, the arc-shaped heat sealing plate 603 of the pressure sealing mechanism 6 heats and seals the vacuum bag (the working principle of the pressure sealing mechanism 6 is as described above). Then, the reset spring 501 and the telescopic column 502 reset (the working principle of the pressing mechanism 4 and the spring material assembly 5 is as described above). Finally, the sealed cured meat is reset upwards and can be easily removed manually.

[0041] In summary, by utilizing the above-mentioned technical solution of this utility model, when the cured meat completes a series of processing steps and is then packaged, a sealing device is used to seal the cured meat. The sealing process involves a pressing mechanism 4, a spring material assembly 5, and a sealing mechanism 8. After the cured meat is processed, the pressing mechanism 4 and the sealing mechanism 8 work together. When the pressing mechanism 4 begins to apply downward pressure, the sealing mechanism 8 on the top mounting frame 1 performs initial sealing and air extraction. When the pressure of the pressing mechanism 4 reaches the bottom of the spring material assembly 5, the bottom sealing mechanism 8 performs final sealing and air extraction. This improves the sealing performance and the tightness of the product seal, enhances the reliability of the seal, improves product quality, and preserves the taste of the cured meat. Finally, a heat-sealing mechanism 6 is used to further improve the sealing performance. After the cured meat is sealed, the pressing mechanism 4 rises, the spring material assembly 5 resets, and the sealed cured meat rises upwards for easy manual removal, improving the convenience of the device and increasing the efficiency of the sealing production process. By incorporating a pressing mechanism 4, the elastic spring 404, rubber pad 405, and rubber pad cloth 406 press and deflate the cured meat. The rubber pad 405 and rubber pad cloth 406 conform to the shape of the cured meat during this process. When the elastic spring 404 contracts under pressure, the rubber pad 405 and rubber pad cloth 406 adhere to the vacuum bag containing the cured meat. Then, with the cooperation of the sealing mechanism 8, a vacuum seal is achieved, improving sealing performance and the tightness of the seal, thus enhancing product quality. Furthermore, by incorporating the sealing mechanism 8, the suction head 803 at the top of the mounting frame 1 initially vacuums the cured meat inside the vacuum bag. Then, when the pressing mechanism 4 presses downwards, the suction head 803 at the bottom performs a second vacuum extraction, enhancing the reliability of the seal and preserving the flavor of the cured meat. By incorporating the spring assembly 5, when the pressing mechanism 4 presses down, it presses the return spring 501. Then, when the pressing mechanism 4 rises, it resets the vacuum-sealed cured meat on the return plate 503, allowing for manual removal and improving the efficiency and convenience of the sealing process. By incorporating the sealing mechanism 6, the position of the arc-shaped heat-sealing plate 603 is adjusted using the drive motor 604. Then, the arc-shaped heat-sealing plate 603 is electrically connected for heating and sealing, improving sealing performance and enhancing product quality.
