Description

Technical Field

[0001] The present invention relates to the field of three-side seal packaging machines, and particularly to a three-side seal packaging machine with a shock-absorbing function. Background Art

[0002] A three-side seal packaging machine is a device used to package products in a packaging bag with three-side seals. The three-side seal packaging machine forms a bag from packaging materials (such as plastic film), then places the product into the bag, and finally seals three sides of the packaging bag. This packaging form can effectively protect the product from moisture, contamination, and oxidation, and extend the shelf life of the product. A three-side seal packaging machine with a shock-absorbing function is a device that adds a shock-absorbing function on the basis of a traditional three-side seal packaging machine. This packaging machine is mainly used to package products, and ensures the tightness and freshness of the product through the three-side sealing method. The addition of the shock-absorbing function can reduce the vibration generated during the packaging process, thereby protecting the product inside the package from damage.

[0003] For example, as disclosed in a three-side seal packaging machine with a shock-absorbing function in Chinese Patent CN212125751U, when the packaging machine body works, it will generate vibrations. The force generated by the vibrations will move the shock-absorbing column downward, and then squeeze the connecting plate. The buffer cross block is driven to move in the buffer cross groove through the buffer inclined rod, and the first buffer spring is compressed. At the same time, the cross plate is driven to move downward through the dispersion rod, and then the second buffer spring is compressed, thereby damping the packaging machine body. The sliding column is driven to move downward through the connecting block, squeezing the fourth spring, and at the same time, the third spring can further play a shock-absorbing effect, further dispersing the vibration force generated by the packaging machine body and improving the shock-absorbing effect.

[0004] For this structure, although the three-side seal packaging machine can be shock-absorbed, the shock-absorbing strength of this structure is inconvenient to adjust. Therefore, we propose a three-side seal packaging machine with a shock-absorbing function that can adjust the shock-absorbing strength according to the weight of the three-side seal packaging machine to improve the shock-absorbing effect. Summary of the Invention

[0005] The purpose of the present invention is to provide a three-side seal packaging machine with a shock-absorbing function to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the present invention provides the following technical solution: A three-side seal packaging machine with a shock-absorbing function, including a bottom plate, a placement plate is arranged above the bottom plate, a three-side seal packaging machine body is arranged on the top surface of the placement plate, and a processing component is arranged outside the three-side seal packaging machine body. The processing component includes a shock-absorbing component arranged outside the three-side seal packaging machine, a clamping component is arranged above the shock-absorbing component, and a fixing component is arranged below the clamping component.

[0007] According to the above technical solution, the shock absorption assembly includes a support block fixedly installed on the top surface of the bottom plate. A square rod is fixedly installed inside the support block. A retaining ring is fixedly installed on the outer wall of the square rod. An oppositely threaded rod is rotatably connected inside the square rod. A sleeve plate is sleeved on the outer wall of the oppositely threaded rod. A spring is fixedly installed on the side wall of the sleeve plate. A sleeve ring is slidably arranged on the outer wall of the square rod. A connecting plate is hinged on the outer wall of the sleeve ring. A sliding rod is fixedly installed at the bottom of the placement plate. A sealing ring is fixedly installed at one end of the sliding rod away from the placement plate. An air pipe is slidably arranged on the outer wall of the sealing ring. A fixing block is fixedly installed on the outer wall of the air pipe. An airbag is communicated at the end of the fixing block. A support plate is fixedly installed at the bottom of the airbag. A connecting frame is fixedly installed on the outer wall of the support plate.

[0008] According to the above technical solution, the clamping assembly includes a rod frame fixedly installed on the top surface of the placement plate. A limiting ring is fixedly installed on the outer wall of the rod frame. A clamping plate is slidably arranged on the outer wall of the rod frame. An inclined groove is formed on the outer wall of the clamping plate. A sliding column is slidably arranged inside the inclined groove. A push plate is fixedly installed at the end of the sliding column. A push block is fixedly installed on the top surface of the push plate. A screw rod is rotatably connected at the end of the push block. A vertical plate is sleeved on the outer wall of the screw rod.

[0009] According to the above technical solution, the fixing assembly includes a rigid tube sleeved inside the bottom plate. A limiting ring is fixedly sleeved on the outer wall of the rigid tube. A suction cup is fixedly installed at the end of the rigid tube. A sealing bolt is sleeved inside the rigid tube.

[0010] According to the above technical solution, the sleeve plate is slidably arranged with the square rod, and the oppositely threaded rod is threadedly sleeved with the sleeve plate. Under its restriction, the rotating oppositely threaded rod drives the sleeve plate to slide on the outer wall of the square rod.

[0011] According to the above technical solution, one end of the spring is fixedly installed on the side of the sleeve plate close to the retaining ring, and the other end of the spring away from the sleeve plate is fixedly installed on the side of the retaining ring close to the sleeve plate. Under the elastic action of the spring, the shock absorption treatment can be carried out on the three-side sealing packaging machine body.

[0012] According to the above technical solution, the inclined groove is obliquely formed, and the outer wall of the sliding column is slidably arranged inside the inclined groove. Under the restriction of the obliquely formed inclined groove, the sliding column moving towards the three-side sealing packaging machine body presses against the inner wall of the inclined groove, and the inclined groove drives the clamping plate to move towards the clamping plate direction, and the two clamping plates clamp the outer wall of the three-side sealing packaging machine body.

[0013] According to the above technical solution, the suction cup is made of soft material, and the number of the suction cups is four, which are divided into two groups and symmetrically distributed with respect to the center line of the top surface of the bottom plate. Under the sleeving of the sealing bolt, the rigid tube and the suction cup are in a sealed state, and the bottom plate is stably adsorbed on the ground.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. The three-side sealing packaging machine with shock absorption function of the present invention has a shock absorption component as one of its components. When the three-side sealing packaging machine body works, it will generate vibrations and needs to be shock-absorbed. When the three-side sealing packaging machine body applies a vibration force to the placement plate, the placement plate pushes the collar through the connecting plate hinged at its bottom. The collar slides on the outer wall of the square rod and compresses the spring sleeved on the outer wall of the square rod. Under the restriction of the spring, the vibration force generated by the three-side sealing packaging machine body can be shock-absorbed, and then the shaking force generated by the spring is offset by the damping shock-absorbing column (the damping shock-absorbing column is a known prior art and is not shown in the figure). When the gravity of the three-side sealing packaging machine body increases, at this time, it is necessary to adjust the shock absorption strength of the spring. At this time, rotate the opposing threaded rod. Since the sleeve plate is slidably arranged with the square rod, under its restriction, the rotating opposing threaded rod drives the two sleeve plates to move towards each other, making the shock absorption harder to shock-absorb the three-side sealing packaging machine body.

[0015] 2. The three-side sealing packaging machine with shock absorption function of the present invention has a shock absorption component as one of its components. When the placement plate moves downward, it drives the sliding rod and the sealing ring fixedly installed at the bottom to slide into the trachea. Since the sealing ring slides in a sealed manner with the trachea, under its restriction, the sealing ring sliding into the trachea pushes the gas inside the trachea, causing the trachea to inflate the airbag inside, and assisting in supporting and cushioning the downward-moving placement plate. Under the support of the connecting frame, the airbag and the support plate stably cushion the placement plate. When the three-side sealing packaging machine body drives the placement plate to move upward, the sliding rod drives the sealing ring to slide in the direction outside the trachea, sucking air from the airbag. At this time, the airbag no longer expands, so as to support and buffer the bottom of the placement plate next time. There are four connecting frames, which can stably support the support plate and the airbag. Under the support of the fixed block, the trachea and the sliding rod slide stably.

[0016] 3. The three-side sealing packaging machine with shock absorption function of the present invention has a clamping component as one of its components. When the three-side sealing packaging machine body is used, it needs to be shock-absorbed. Place the three-side sealing packaging machine body on the top surface of the placement plate and rotate the screw. Since the clamping plate is slidably arranged with the rod frame, and the sliding column is slidably arranged with the inclined groove, under its restriction, the rotating screw pushes the push block, causing the push block to drive the push plate and the sliding column to move. Since the inclined groove is inclined, under its restriction, the sliding column moving towards the three-side sealing packaging machine body squeezes the inner wall of the inclined groove, causing the two clamping plates to move towards each other to clamp the three-side sealing packaging machine body. This structure can stably place the three-side sealing packaging machine body on the top surface of the placement plate, so that the placement plate can stably shock-absorb it.

[0017] 4. The three-side sealing packaging machine with shock absorption function according to the present invention has a fixing component as one of its components. When placing the three-side sealing packaging machine body, the bottom plate needs to be stably placed on the ground. Remove the sealing bolt from the inside of the hard pipe. Place the bottom plate, the placing plate and the three-side sealing packaging machine body on the ground. Under the action of gravity, press the suction cup so that the suction cup is closely attached to the ground. Then, sleeve the sealing bolt inside the hard pipe. At this time, under the restriction of the sealing bolt, the inside of the hard pipe and the suction cup is hermetically arranged. Under its restriction, the bottom plate is tightly adsorbed on the ground. This structure can prevent the bottom plate from shifting due to the shaking of the three-side sealing packaging machine body during operation. BRIEF DESCRIPTION OF THE DRAWINGS

For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Embodiment 1: A preferred embodiment of a three-side sealing packaging machine with a shock absorption function provided by the present invention is as follows Figures 1 to 9 As shown: A three-side sealing packaging machine with a shock absorption function includes a bottom plate 1; A placement plate 2 is arranged above the bottom plate 1; The top surface of the placement plate 2 is provided with a three-side sealing packaging machine body 3; And a processing component 4 arranged outside the three-side sealing packaging machine body 3. The processing component 4 includes a shock absorption component 41 arranged outside the three-side sealing packaging machine body 3. The shock absorption component 41 includes a support block 411 fixedly installed on the top surface of the bottom plate 1. A square rod 412 is fixedly installed inside the support block 411. A retaining ring 413 is fixedly installed on the outer wall of the square rod 412. An oppositely threaded rod 414 is rotatably connected inside the square rod 412. A sleeve plate 415 is sleeved on the outer wall of the oppositely threaded rod 414. A spring 416 is fixedly installed on the side wall of the sleeve plate 415. A sleeve ring 417 is slidably arranged on the outer wall of the square rod 412. A connecting plate 418 is hinged on the outer wall of the sleeve ring 417. A sliding rod 419 is fixedly installed at the bottom of the placement plate 2. A sealing ring 420 is fixedly installed at the end of the sliding rod 419 away from the placement plate 2. An air pipe 421 is slidably arranged on the outer wall of the sealing ring 420. A fixing block 422 is fixedly installed on the outer wall of the air pipe 421. An airbag 423 is communicated at the end of the fixing block 422. A support plate 424 is fixedly installed at the bottom of the airbag 423. A connecting frame 425 is fixedly installed on the outer wall of the support plate 424.

[0024] In this embodiment, when the three-side sealing packaging machine body 3 works, it will generate vibrations and needs to be shock-absorbed. When the three-side sealing packaging machine body 3 applies a vibration force to the placement plate 2, the placement plate 2 pushes the collar 417 through the connecting plate 418 hinged to its bottom. The collar 417 slides on the outer wall of the square rod 412 and compresses the spring 416 sleeved on the outer wall of the square rod 412. Under the restriction of the spring 416, the vibration force generated by the three-side sealing packaging machine body 3 can be shock-absorbed. Then, the shaking force generated by the spring 416 is offset by the damping shock-absorbing column (the damping shock-absorbing column is a well-known prior art and is not shown in the figure). When the gravity of the three-side sealing packaging machine body 3 increases, at this time, it is necessary to adjust the shock-absorbing strength of the spring 416. At this time, the opposed threaded rod 414 is rotated. Since the sleeve plate 415 is slidably arranged with the square rod 412, under its restriction, the rotated opposed threaded rod 414 drives the two sleeve plates 415 to move towards each other, making the shock absorption harder to perform shock-absorbing treatment on the three-side sealing packaging machine body 3. When the placement plate 2 moves downward, it drives the sliding rod 419 fixedly installed at its bottom and the sealing ring 420 to slide into the trachea 421. Since the sealing ring 420 seals and slides with the trachea 421, under its restriction, the sealing ring 420 sliding into the trachea 421 pushes the gas inside the trachea 421, so that the trachea 421 inflates the inside of the airbag 423 to assist in supporting and cushioning the downward-moving placement plate 2. Supported by the connecting frame 425, the airbag 423 and the support plate 424 stably cushion the placement plate 2. When the three-side sealing packaging machine body 3 drives the placement plate 2 to move upward, the sliding rod 419 drives the sealing ring 420 to slide towards the outside of the trachea 421, sucking air from the airbag 423. At this time, the airbag 423 no longer expands, so as to support and buffer the bottom of the placement plate 2 next time. There are four connecting frames 425, which can stably support the support plate 424 and the airbag 423. Supported by the fixed block 422, the trachea 421 and the sliding rod 419 stably slide.

[0025] Embodiment 2: A preferred embodiment of a three-side sealing packaging machine with a shock-absorbing function provided by the present invention is as Figures 1 to 9 shown: The clamping assembly 43 includes a rod frame 431 fixedly installed on the top surface of the placement plate 2. A limit ring 432 is fixedly installed on the outer wall of the rod frame 431. A clamping plate 433 is slidably arranged on the outer wall of the rod frame 431. An inclined groove 434 is formed on the outer wall of the clamping plate 433. A sliding column 435 is slidably arranged inside the inclined groove 434. A push plate 436 is fixedly installed at the end of the sliding column 435. A push block 437 is fixedly installed on the top surface of the push plate 436. One end of the push block 437 is rotatably connected to a screw rod 438. A vertical plate 439 is sleeved on the outer wall of the screw rod 438.

[0026] In this embodiment, when the three-side sealing packaging machine body 3 is in use, it is necessary to shock-absorb it. Place the three-side sealing packaging machine body 3 on the top surface of the placing plate 2, and rotate the screw rod 438. Since the clamping plate 433 is slidably arranged on the rod frame 431, and the sliding column 435 is slidably arranged in the inclined groove 434, under its limitation, the rotating screw rod 438 pushes the push block 437, so that the push block 437 drives the push plate 436 and the sliding column 435 to move. Since the inclined groove 434 is inclined, under its limitation, the sliding column 435 moving towards the three-side sealing packaging machine body 3 presses against the inner wall of the inclined groove 434, so that the two clamping plates 433 move towards each other to clamp the three-side sealing packaging machine body 3. This structure can stably place the three-side sealing packaging machine body 3 on the top surface of the placing plate 2, so that the placing plate 2 can stably shock-absorb it.

[0027] Embodiment 3: A preferred embodiment of the three-side sealing packaging machine with a shock-absorbing function provided by the present invention is as Figures 1 to 9 shown: The fixing assembly 44 includes a hard tube 441 sleeved inside the bottom plate 1, a limiting ring 442 is fixedly sleeved on the outer wall of the hard tube 441, a suction cup 443 is fixedly installed at the end of the hard tube 441, and a sealing plug 444 is sleeved inside the hard tube 441.

[0028] In this embodiment, when placing the three-side sealing packaging machine body 3, it is necessary to stably place the bottom plate 1 on the ground, remove the sealing plug 444 from the inside of the hard tube 441, place the bottom plate 1, the placing plate 2 and the three-side sealing packaging machine body 3 on the ground. Under the action of gravity, the suction cup 443 is pressed so that the suction cup 443 is in close contact with the ground, and then the sealing plug 444 is sleeved inside the hard tube 441. At this time, under the limitation of the sealing plug 444, the inside of the hard tube 441 and the suction cup 443 is hermetically arranged. Under its limitation, the bottom plate 1 is tightly adsorbed on the ground. This structure can prevent the bottom plate 1 from shifting due to the shaking of the three-side sealing packaging machine body 3 during operation.

[0029] Among them, the sleeve plate 415 is slidably arranged on the square rod 412, and the opposing threaded rod 414 is threadedly sleeved on the sleeve plate 415. Under its limitation, the rotating opposing threaded rod 414 drives the sleeve plate 415 to slide on the outer wall of the square rod 412.

[0030] Among them, one end of the spring 416 is fixedly installed on the side of the sleeve plate 415 close to the retaining ring 413, and the end of the spring 416 far from the sleeve plate 415 is fixedly installed on the side of the retaining ring 413 close to the sleeve plate 415. Under the elastic action of the spring 416, the three-side sealing packaging machine body 3 can be shock-absorbed.

[0031] Among them, the inclined groove 434 is formed in an inclined manner, and the outer wall of the sliding column 435 is slidably arranged inside the inclined groove 434. Under the restriction of the inclined groove 434 formed in an inclined manner, the sliding column 435 moving towards the three-side sealing packaging machine body 3 squeezes the inner wall of the inclined groove 434, and the inclined groove 434 drives the clamping plate 433 to move towards the clamping plate 433, and the two clamping plates 433 clamp the outer wall of the three-side sealing packaging machine body 3.

[0032] Among them, the suction cup 443 is made of a soft material. The number of suction cups 443 is four, which are divided into two groups and symmetrically distributed with respect to the center line of the top surface of the bottom plate 1. Under the sleeving of the sealing bolt 444, the hard tube 441 and the suction cup 443 are in a sealed state, and the bottom plate 1 is stably adsorbed on the ground.
