Description

Technical Field

[0001] The present invention belongs to the technical field of vacuum sealing equipment, and more specifically, it is a vacuum sealer with a flattening structure. Background Art

[0002] A vacuum sealer is a device often used in food preservation. When in use, food is put into a packaging bag. First, the vacuum sealer is used to pump out the air in the packaging bag. After the predetermined vacuum degree is reached in the packaging bag, the opening of the packaging bag is sealed to maintain a vacuum and low-oxygen environment inside the packaging bag, thereby extending the storage time of the food.

[0003] When the opening of the packaging bag is put over the vacuum suction pipe of the vacuum sealer, the packaging bag often has wrinkles because the opening fails to be flattened. The existence of these wrinkles is not conducive to the vacuum sealer in pumping out the air, and the existing similar products lack the function of flattening these wrinkles. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the present invention to solve its technical problems is: a vacuum sealer with a flattening structure, including: a machine body, a cover body is rotatably connected to the top of the machine body, and a mounting frame is fixedly connected inside the machine body;

[0005] The vacuum sealer with a flattening structure further includes:

[0006] A limiting mechanism, the bottom of the limiting mechanism is fixedly connected to the bottom of the inner wall of the mounting frame;

[0007] The limiting mechanism includes a lifting column, the bottom of the lifting column is fixedly connected to the bottom of the inner wall of the mounting frame, the top of the lifting column is fixedly connected to a housing, and a sealing component is rotatably connected to the outer wall of the housing;

[0008] An adjustment mechanism, the bottom of the adjustment mechanism is fixedly connected to the bottom of the inner wall of the mounting frame on the side away from the sealing component;

[0009] The adjustment mechanism includes a base, a heating plate is fixedly connected to the top of the base, sliders are uniformly arranged on the side of the top of the base away from the heating plate, the bottom of the slider is slidably connected to the top of the base, the top of the slider is fixedly connected to a flattening component, and it is pulled towards both ends to keep the opening flat. After covering the cover body, the flattening component retracts, the vacuum pumping is started and then the sealing is carried out, so that the surface of the packaging bag is flat during sealing, avoiding the appearance of wrinkles and affecting the sealing effect.

[0010] Furthermore, pressing strips are symmetrically arranged at the bottom of the cover body, the top of the pressing strip is fixedly connected to the bottom of the cover body, and an auxiliary mechanism is fixedly connected to the bottom of the inner wall of the mounting frame on the side close to the adjustment mechanism.

[0011] Furthermore, the limiting mechanism further includes an elastic rod. The outer wall of the elastic rod is fixedly connected to the inner wall of the frame. A mesh bag is fixedly connected to the inner wall of the frame. The bottom of the mesh bag contacts the surface of the elastic rod, pressing the opening of the packaging bag from the upper and lower sides and keeping the pressing position closer to the food. Thus, there is a wider sealing range on one side of the opening of the packaging bag. At the same time, it is more conducive to the flattening assembly to adjust the opening, keeping the packaging bag flat and then heat-sealing it. Even when there is more food in the packaging bag, it can be sealed, preventing the food from spilling out, saving the space used by the packaging bag, and leaving a certain adjustment space before sealing the packaging bag, which is more conducive to the tightness of the seal.

[0012] Furthermore, the auxiliary mechanism includes a roller. The outer wall of the roller is rotatably connected to the inner wall of the mounting frame. Silicone strips are evenly arranged on the outer wall of the roller, and the outer walls of the silicone strips are fixedly connected to the outer wall of the roller. Rotating rings are symmetrically arranged at both ends of the roller. The outer wall of the rotating ring is rotatably connected to the outer wall of the rotating shaft. An adsorption assembly is fixedly connected to the top of the rotating ring. The outer wall of the adsorption assembly is rotatably connected to a pressing rod. Magnets are evenly arranged on the outer wall of the pressing rod, and the inner walls of the magnets are slidably connected to the outer wall of the pressing rod. Since the packaging bag is placed obliquely, the food contained therein may roll obliquely to a certain extent. When the pressing rod is lifted, it can intercept the food spilling out of the packaging bag. The sealing assembly rotates to attract the magnets on the pressing rod, thereby closing the opening of the packaging bag and making the closed part closer to the food, thus pre-pressing the packaging bag. Also, because the magnets are convex and dispersed, when they attract the sealing assembly, there are still gaps at the sealing part of the packaging bag, enabling vacuum pumping to be completed.

[0013] Furthermore, the adsorption assembly includes a telescopic column. The bottom of the telescopic column is fixedly connected to the top of the rotating ring. A fixed rod is fixedly connected to the top of the telescopic column. Adsorption blocks are evenly arranged on the outer wall of the fixed rod, and the inner walls of the adsorption blocks are fixedly connected to the outer wall of the fixed rod. An arc surface is arranged at the bottom of the adsorption block. An air pipe is fixedly connected to the top of the adsorption block, so that after the adsorption block contacts the upper surface of the packaging bag, the holes at the bottom of the arc surface can be blocked, generating negative pressure to adsorb the upper surface of the packaging bag, and then lifting it to open the opening of the packaging bag for the flattening assembly to insert.

[0014] Further, the sealing assembly includes a rotating rod, the outer wall of the rotating rod is rotatably connected to the outer wall of the housing, two rotating rods are symmetrically arranged, a connecting rod is fixedly connected to the opposite side of the rotating rod, both ends of the connecting rod are fixedly connected to the outer wall of the rotating rod, elastic ropes are evenly arranged on the outer wall of the connecting rod, the outer wall of the elastic rope is fixedly connected to the outer wall of the connecting rod, one end of the elastic rope away from the connecting rod is fixedly connected to an arc-shaped plate, the bottom of the arc-shaped plate is rotatably connected to the top of the frame, and support plates are evenly arranged at one end of the arc-shaped plate away from the connecting rod. The connecting rod is made of metal and can be attracted by a magnet, so as to realize the preliminary sealing of the packaging bag. The arc-shaped plate and the support plates can lift the packaging bag upward, so that the food in the packaging bag is clamped between the connecting rod and the arc-shaped plate, which can expand the utilization range of the opening of the packaging bag and make the sealing position closer to the food, thereby improving the utilization rate of the space of the packaging bag.

[0015] Further, the flattening assembly includes a hydraulic cylinder, the bottom of the hydraulic cylinder is fixedly connected to the top of the slider, the top of the hydraulic cylinder is fixedly connected to an I-shaped block, rotating shafts are symmetrically arranged on the inner wall of the I-shaped block, the top of the rotating shaft is rotatably connected to the top of the inner wall of the I-shaped block, elastic blocks are symmetrically arranged at the bottom of the rotating shaft, the outer wall of the elastic block is sleeved on the bottom of the rotating shaft, movable rods are symmetrically arranged at the bottom of the inner wall of the I-shaped block, the bottom of the movable rod is slidably connected to the bottom of the inner wall of the I-shaped block, one end of the outer wall of the I-shaped block away from the heating plate is fixedly connected to a telescopic rod, the telescopic rod away from the I-shaped block is fixedly connected to a connecting frame, and the inner wall of the connecting frame is slidably connected to the outer wall of the movable rod, so that the movable rod completes the action of opening to both sides after being inserted into the packaging bag, the movable rod stretches the packaging bag to both sides from the inside, thereby flattening the opening of the packaging bag, and then the adsorption assembly buckles downward to keep the opening of the packaging bag in a certain state and then performs vacuum sealing, avoiding the packaging bag from wrinkling during the vacuum pumping and sealing processes, thereby affecting the sealing effect.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. When the opening of the packaging bag is sleeved on the vacuum suction pipe of the vacuum sealer, the packaging bag often wrinkles because the opening is not flattened. The existence of these wrinkles is not conducive to the vacuum sealer to pump vacuum. By setting an adjustment mechanism, after the packaging bag is opened, the flattening assembly is inserted into the interior of the packaging bag and pulled towards both ends to keep the opening flat. After covering the cover body, the flattening assembly retracts, the vacuum is pumped, and then sealing is carried out, so that the surface of the packaging bag is flat during sealing, avoiding wrinkles and affecting the sealing effect.

[0018] 2. The present invention presses the opening of the packaging bag from the upper and lower sides by setting a limiting mechanism, and keeps the pressing position closer to the food, so that there is a wider sealing range on one side of the opening of the packaging bag. At the same time, it is more conducive to the flattening component to adjust the opening, keep the packaging bag flat, and then heat-seal it, so that the packaging bag can be sealed even when there is more food in it, making the food not easy to spill out, saving the space usage of the packaging bag. Before sealing the packaging bag, a certain adjustment space is reserved, which is more conducive to the tightness of the seal.

[0019] 3. The present invention sets a sealing component to support the bottom of the packaging bag containing food, enabling it to be closer to the roller, so that the remaining part of the packaging bag can be lifted upward. The rotating rod drives the connecting rod to contact the magnetic block. The connecting rod is made of metal and can be attracted by the magnetic block, thus realizing the preliminary sealing of the packaging bag. The arc-shaped plate and the support plate can lift the packaging bag upward, sandwiching the food in the packaging bag between the connecting rod and the arc-shaped plate, which can expand the utilization range of the opening of the packaging bag, make the sealing position closer to the food, and thus improve the utilization rate of the space of the packaging bag.

[0020] 4. The present invention sets a flattening component to make the movable rod open to both sides after being inserted into the packaging bag, stretching the packaging bag from the inside to both sides, thus flattening the opening of the packaging bag. Then the adsorption component buckles downward to keep the opening of the packaging bag in a certain state and then perform vacuum pumping and sealing, avoiding the packaging bag from wrinkling during the vacuum pumping and sealing processes, which may affect the sealing effect.

Specific embodiments

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are given for purposes of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed form. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

[0032] Example 1, please refer to Figures 1 - 5 , the present invention provides a technical solution: A vacuum sealer with a flattening structure will be described as follows.

[0033] Including: the body 1, the cover body 2 is rotatably connected to the top of the body 1, and the mounting rack 4 is fixedly connected to the inside of the body 1;

[0034] This vacuum sealer with a flattening structure further includes:

[0035] The limiting mechanism 6, the bottom of the limiting mechanism 6 is fixedly connected to the bottom of the inner wall of the mounting rack 4;

[0036] The limiting mechanism 6 includes the lifting column 601, the bottom of the lifting column 601 is fixedly connected to the bottom of the inner wall of the mounting rack 4, the top of the lifting column 601 is fixedly connected to the housing 602, and the outer wall of the housing 602 is rotatably connected to the sealing component 604;

[0037] The adjustment mechanism 7, the bottom of the adjustment mechanism 7 is fixedly connected to the bottom of the inner wall of the mounting rack 4 on the side away from the sealing component 604;

[0038] At the bottom of the cover body 2, pressing strips 3 are symmetrically arranged. The top of the pressing strip 3 is fixedly connected to the bottom of the cover body 2. At the bottom of the inner wall of the mounting frame 4, on one side close to the adjusting mechanism 7, an auxiliary mechanism 5 is fixedly connected.

[0039] During operation, first open the cover plate, place the packaging bag to be sealed on the top of the limiting mechanism 6, make the opening of the packaging bag face the adjusting mechanism 7. Subsequently, the auxiliary mechanism 5 unfolds the opening of the packaging bag, enables the adjusting mechanism 7 to insert and flatten the opening of the packaging bag. At the same time, with the cooperation of the auxiliary mechanism 5 and the limiting mechanism 6, the food in the packaging bag is intercepted. After flattening the opening of the packaging bag, the adjusting mechanism 7 extracts the auxiliary mechanism 5 and presses the opening of the packaging bag on the heating plate 702. Then manually cover the cover body 2, start the vacuum extraction device in the machine body 1. After all the air in the packaging bag is extracted, the heating plate 702 heats the sealing part. When the cover body 2 covers the machine body 1, the pressing strip 3 contacts the heating plate 702, presses the opening of the packaging bag, so that the packaging bag can be heat-sealed.

[0040] The limiting mechanism 6 further includes an elastic rod 606. The elastic rod 606 is made of elastic material. Its purpose is to divide the mesh bag 605 into three parts, facilitating the mesh bag 605 to accommodate packaging bags with more food loaded. The outer wall of the elastic rod 606 is fixedly connected to the inner wall of the frame 603. The inner wall of the frame 603 is fixedly connected with a mesh bag 605. The mesh bag 605 has elasticity, so that when a relatively bulging packaging bag is placed at the bottom and is held by the mesh bag, the opening can be more stable. The bottom of the mesh bag 605 contacts the surface of the elastic rod 606.

[0041] Initially, the user places the packaging bag containing food on the mesh bag 605 and manually places the opening of the packaging bag into the auxiliary mechanism 5. When objects such as apples are loaded into the packaging bag, the opening of the packaging bag is not easy to close and is not easy to place, and is more likely to have wrinkles. Since the mesh bag 605 has elasticity, when such a packaging bag is placed inside, the mesh bag 605 is squeezed, enabling the opening of the packaging bag to be placed stably. After placing the packaging bag, the end close to the opening is opened by the auxiliary mechanism 5, facilitating the adjusting mechanism 7 to insert and flatten. Since the frame 603 is inclined, the opening of the food in the packaging bag faces upward and is not easy to spill. At this time, the sealing component 604 rotates and cooperates with the auxiliary mechanism 5 to move closer to each other, pressing the opening of the packaging bag tightly from the upper and lower sides, and keeping the pressing position closer to the food. Thus, there is a wider sealing range on one side of the opening of the packaging bag, and at the same time, it is more beneficial for the flattening component 704 to adjust the opening, keeping the packaging bag flat, and then heat-sealing, so that the packaging bag can be sealed even when more food is loaded and unloaded, making the food not easy to spill, saving the space usage of the packaging bag. Before sealing the packaging bag, a certain adjustment space is reserved, which is more beneficial for the tightness of the seal.

[0042] The auxiliary mechanism 5 includes a roller 501. The outer wall of the roller 501 is rotatably connected to the inner wall of the mounting bracket 4. The outer wall of the roller 501 is evenly provided with silica gel strips 503, and the outer wall of the silica gel strips 503 is fixedly connected to the outer wall of the roller 501. Rotating rings 502 are symmetrically arranged at both ends of the roller 501, and the outer wall of the rotating ring 502 is rotatably connected to the outer wall of the rotating shaft 7042. An adsorption assembly 504 is fixedly connected to the top of the rotating ring 502, a pressure lever 505 is rotatably connected to the outer wall of the adsorption assembly 504, magnetic blocks 506 are evenly arranged on the outer wall of the pressure lever 505, and the inner wall of the magnetic blocks 506 is slidably connected to the outer wall of the pressure lever 505.

[0043] After the packaging bag is placed on the mesh bag 605, its opening is placed on the roller 501 and the pressure lever 505. The rotating direction of the roller 501 is the same as the direction of the opening of the packaging bag, so that the silica gel strip 503 adheres to the bottom of the packaging bag. Subsequently, the adsorption assembly 504 sucks the top of the packaging bag. After being fixed up and down, the packaging bag is opened, so that the adjustment mechanism 7 can be inserted into the inside of the opening of the packaging bag to flatten it. The pressure lever 505 rotates and lifts. Since the packaging bag is placed obliquely, the food contained in it may roll obliquely to a certain extent. The lifting of the pressure lever 505 can intercept the food in the packaging bag from spilling out. The sealing assembly 604 rotates to attract the magnetic block 506 on the pressure lever 505, so that the opening of the packaging bag is closed, and the closed part is closer to the food, so as to pre-press the packaging bag. Also, because the magnetic blocks 506 are convex and dispersed, when it attracts the sealing assembly 604, there are also gaps at the sealing part of the packaging bag, and vacuum pumping can be completed.

[0044] The adjustment mechanism 7 includes a base 701. A heating plate 702 is fixedly connected to the top of the base 701. Sliders 703 are evenly arranged on one side of the top of the base 701 away from the heating plate 702. The bottom of the slider 703 is slidably connected to the top of the base 701. A flattening assembly 704 is fixedly connected to the top of the slider 703.

[0045] After the packaging bag is pre-pressed, the excess part of the opening of the packaging bag is placed on the heating plate 702. As the opening is opened, the slider 703 moves to a suitable position. Subsequently, the flattening assembly 704 is inserted into the inside of the packaging bag and pulled towards both ends to keep the opening flat. After covering the cover body 2, the flattening assembly 704 retracts. Vacuum pumping is started and then sealing is carried out, so that the surface of the packaging bag is flat when sealed, and wrinkles are avoided from affecting the sealing effect.

[0046] Example 2, please refer to Figures 1 - 9, the present invention provides a technical solution: on the basis of Embodiment 1, the adsorption component 504 includes a telescopic column 5041. The bottom of the telescopic column 5041 is fixedly connected to the top of the swivel ring 502. The top of the telescopic column 5041 is fixedly connected to a fixed rod 5042. Adsorption blocks 5043 are evenly arranged on the outer wall of the fixed rod 5042. The inner wall of the adsorption block 5043 is fixedly connected to the outer wall of the fixed rod 5042. An arc surface 5044 is arranged at the bottom of the adsorption block 5043. An air pipe 5045 is fixedly connected to the top of the adsorption block 5043.

[0047] The air pipe 5045 is externally connected to a suction device. During the downward movement of the telescopic column 5041, the bottom of the adsorption block 5043 contacts the upper surface of the packaging bag placed on the roller 501. The arc surface 5044 at the bottom of the adsorption block 5043 fits with the surface of the roller 501, so that after the adsorption block 5043 contacts the upper surface of the packaging bag, the hole at the bottom of the arc surface 5044 can be blocked, thereby generating negative pressure to adsorb the upper surface of the packaging bag, and then lifting it to open the opening of the packaging bag for the flattening component 704 to insert.

[0048] The sealing component 604 includes a rotating rod 6041. The outer wall of the rotating rod 6041 is rotatably connected to the outer wall of the housing 602. There are two symmetrically arranged rotating rods 6041. A connecting rod 6042 is fixedly connected to the opposite side of the rotating rod 6041. Both ends of the connecting rod 6042 are fixedly connected to the outer wall of the rotating rod 6041. Elastic ropes 6043 are evenly arranged on the outer wall of the connecting rod 6042. The outer wall of the elastic rope 6043 is fixedly connected to the outer wall of the connecting rod 6042. One end of the elastic rope 6043 away from the connecting rod 6042 is fixedly connected to an arc plate 6044. The bottom of the arc plate 6044 is rotatably connected to the top of the frame 603. Support plates 6045 are evenly arranged at one end of the arc plate 6044 away from the connecting rod 6042.

[0049] After placing the packaging bag on the mesh bag 605, the rotating rod 6041 rotates. During the rotation, the elastic rope 6043 is straightened, driving the arc plate 6044 to rotate, so that the bottom of the packaging bag containing food is supported and can be closer to the roller 501, making the empty part of the packaging bag able to be lifted upward. The rotating rod 6041 drives the connecting rod 6042 to contact the magnet 506. The connecting rod 6042 is made of metal and can be attracted by the magnet 506, thereby realizing the preliminary sealing of the packaging bag. The arc plate 6044 and the support plates 6045 can lift the packaging bag upward, sandwiching the food in the packaging bag between the connecting rod 6042 and the arc plate 6044, which can expand the utilization range of the opening of the packaging bag and make the sealing position closer to the food, thereby improving the utilization rate of the space of the packaging bag.

[0050] The flattening assembly 704 includes a hydraulic column 7047. The bottom of the hydraulic column 7047 is fixedly connected to the top of the slider 703. The top of the hydraulic column 7047 is fixedly connected with an I-shaped block 7041. The inner walls of the I-shaped block 7041 are symmetrically provided with rotating shafts 7042. The top of the rotating shaft 7042 is rotatably connected to the top of the inner wall of the I-shaped block 7041. The bottom of the rotating shaft 7042 is symmetrically provided with elastic blocks 7043. The outer walls of the elastic blocks 7043 are sleeved on the bottom of the rotating shaft 7042. The bottom of the inner wall of the I-shaped block 7041 is symmetrically provided with movable rods 7044. The bottom of the movable rod 7044 is slidably connected to the bottom of the inner wall of the I-shaped block 7041. One end of the outer wall of the I-shaped block 7041 away from the heating plate 702 is fixedly connected with a telescopic rod 7045. The end of the telescopic rod 7045 away from the I-shaped block 7041 is fixedly connected with a connecting frame 7046. The inner wall of the connecting frame 7046 is slidably connected to the outer wall of the movable rod 7044.

[0051] After the adsorption assembly 504 opens the opening of the packaging bag, the telescopic rod 7045 drives the connecting frame 7046 to approach the packaging bag, so that the movable rod 7044 is inserted into the interior of the packaging bag. The shape of the movable rod 7044 is Figure Nine as shown. During the process of the movable rod 7044 moving along the I-shaped block 7041, the rotating shaft 7042 slides along the inner wall of the movable rod 7044. When the rotating shaft 7042 contacts the hollow part of the movable rod 7044, the elastic block 7043 pops out, so that the rotating shaft 7042 catches and rotates the movable rod 7044, so that the movable rod 7044 completes the action of opening to both sides after being inserted into the packaging bag, so that the movable rod 7044 stretches the packaging bag to both sides from the inside, and then the opening of the packaging bag is flattened. Then the adsorption assembly 504 buckles downwards to keep the opening of the packaging bag in a state and then evacuates and seals it, avoiding wrinkles in the packaging bag during the evacuation and sealing processes, thereby affecting the sealing effect.

[0052] The specific working process is as follows:

[0053] During operation, first open the cover plate. The user places the food-containing packaging bag on the mesh pocket 605 and manually positions the opening of the packaging bag inside the auxiliary mechanism 5. When objects such as apples are placed in the packaging bag, the opening of the packaging bag is not easily closed, not easily placed, and is more likely to form wrinkles. Since the mesh pocket 605 is elastic, when such a packaging bag is placed inside, the mesh pocket 605 is squeezed, enabling the opening of the packaging bag to be placed stably. After placing the packaging bag, one end near the opening is opened by the auxiliary mechanism 5. Since the frame 603 is inclined, the opening of the food in the packaging bag faces upward. After placing the packaging bag on the mesh pocket 605, its opening is placed on the roller 501 and the pressure bar 505. The rotation direction of the roller 501 is the same as the direction of the opening of the packaging bag, causing the silicone strip 503 to adhere to the bottom of the packaging bag. Subsequently, the adsorption component 504 sucks the top of the packaging bag. After being fixed up and down, the packaging bag is opened, enabling the adjustment mechanism 7 to be inserted into the interior of the opening of the packaging bag to flatten it. The pressure bar 505 rotates and lifts. Since the packaging bag is placed obliquely, the food contained therein may roll obliquely to a certain extent. The lifting of the pressure bar 505 can intercept the spillage of the food in the packaging bag. The sealing component 604 rotates to attract the magnet 506 on the pressure bar 505, thereby closing the opening of the packaging bag and keeping the pressing position closer to the food, resulting in a wider sealing range on one side of the opening of the packaging bag. At the same time, it is more conducive for the flattening component 704 to adjust the opening, keeping the packaging bag flat, and then heat-sealing.
