Description

Technical Field

[0001] This invention relates to the field of packaging sealing technology, specifically to a sealing device for dried bean curd packaging. Background Technology

[0002] Dried tofu, also known as tofu skin, is a traditional Chinese soy product. It is a processed product of tofu, and is salty, savory, and refreshing. It is firm yet chewy, and keeps well for a long time. It is a delicacy found in various Chinese cuisines. It is produced in South China, particularly the Jiangnan region. Dried tofu is rich in nutrients, containing a large amount of protein, fat, and carbohydrates, as well as various minerals such as calcium, phosphorus, and iron, which are essential for the human body. During the production process, salt, fennel, Sichuan peppercorns, star anise, and dried ginger are added, making it fragrant and delicious. It is a food that one never tires of. Dried tofu is mostly packaged in vacuum packaging for storage.

[0003] Chinese patent document CN110510187B discloses a sealing device for dried bean curd packaging bags, including a base. A support frame is fixedly connected to the four corners of the top of the base. From left to right, a collection area, a sealing area, and a conveying area are formed between the bottom of the support frame and the base. Two hydraulic press bases are located at the bottom of the support frame, respectively within the sealing and conveying areas. Threaded blocks are fixedly connected to the top of each hydraulic press base, and a lead screw is threaded between the two threaded blocks. A forward and reverse motor is fixedly connected to one end of the lead screw. Slider blocks are fixedly connected to both sides of each hydraulic press base. A groove matching the slider is provided on the side wall of the support frame. A hydraulic press is fixedly connected to the bottom of the hydraulic press base. By sealing the dried bean curd packaging bag through two vacuum seals, a double-seal effect is achieved, strengthening the sealing effect and providing double-layer protection, thus increasing the shelf life of the dried bean curd.

[0004] However, the above-mentioned patent documents also have the following shortcomings: after the braised tofu is put into the packaging bag, because the braised tofu contains a lot of juice, when the packaging bag is vacuum sealed, the juice inside the packaging bag is easily absorbed to the sealing position of the packaging bag, thus affecting the sealing effect of the packaging bag. Summary of the Invention

[0005] This invention provides a sealing device for dried bean curd packaging, which aims to solve the problem in related technologies that the juice inside the packaging bag is easily absorbed to the sealing position of the packaging bag, thereby affecting the sealing effect of the packaging bag.

[0006] The bean curd packaging sealing device of the present invention includes a worktable, a bag conveying mechanism, a clamping mechanism, a mouth-supporting mechanism, a feeding mechanism, a sealing mechanism, and a conveying mechanism. The bag conveying mechanism, clamping mechanism, mouth-supporting mechanism, feeding mechanism, sealing mechanism, and conveying mechanism are all connected to the worktable. It also includes a lifting part, a mounting frame, a clamping part, and a guide part. The lifting part is connected to the worktable, the mounting frame is connected to the lifting part, and the clamping part and the guide part are both set on the mounting frame. The lifting part can drive the mounting frame to move up and down. There are two guide parts. The two guide parts can approach each other and make close contact with both sides of the packaging bag. The guide parts are provided with guide grooves. The guide grooves on the two guide parts can form a curved path for the air and juice inside the packaging bag to flow.

[0007] Beneficial effects: After the two guide parts come close to each other and make tight contact with both sides of the packaging bag, the guide grooves on the two guide parts create a curved path for the air and juice to flow inside the packaging bag, extending the flow path of the juice and preventing the juice from being absorbed to the sealing position of the packaging bag.

[0008] Preferably, the mounting frame is provided with two sets of clamping parts, each set having two clamping parts. The two clamping parts in the same set can approach each other and clamp the bottom of the packaging bag. The effect is that the bottom of the packaging bag can be clamped by the two sets of clamping parts to prevent the packaging bag from shaking.

[0009] Preferably, the mounting frame is provided with two pushing parts, which are located on both sides of the packaging bag and can tilt downwards synchronously. The effect is that the two synchronously tilting pushing parts can push the tofu at the top of the packaging bag away from the curved path, further preventing the juice inside the tofu from being absorbed into the sealing position of the packaging bag.

[0010] Preferably, the mounting bracket is connected to a second channel, a movable part is inserted into the second channel, a pushing part is connected to the movable part, and a second connecting pipe is connected to the second channel, which can supply air into the second channel. The effect is that supplying air into the second channel through the second connecting pipe can drive the movable part to move, thereby providing power for the tilting movement of the pushing part.

[0011] Preferably, the mounting bracket is connected to two channels 3, each channel 3 is connected to a telescopic part, and two guide parts are respectively connected to the two telescopic parts.

[0012] Preferably, a connecting pipe is provided between channel three and channel two, and the movable part is capable of sealing one end of the connecting pipe.

[0013] Preferably, a magnetic block one is connected to the moving part, and a magnetic block two is connected to the channel two. The effect is that, through magnetic blocks one and two, the telescopic part can drive the guide part to reset, and then the moving part can drive the pushing part to reset.

[0014] Preferably, the mounting bracket is provided with a through groove, and the moving part is slidably connected in the through groove.

[0015] The beneficial effects of this invention are:

[0016] 1. After the two guide parts come close to each other and make tight contact with both sides of the packaging bag, the guide grooves on the two guide parts create a curved path for the air and juice to flow inside the packaging bag, extending the flow path of the juice and preventing the juice from being absorbed to the sealing position of the packaging bag, thereby avoiding affecting the sealing effect of the packaging bag.

[0017] 2. The bottom of the packaging bag is held by two sets of clamping parts, and the top of the dried bean curd inside the packaging bag is pushed by two synchronously tilted and downward pushing parts, so that the top of the dried bean curd is away from the bending path, further preventing the juice inside the dried bean curd from being absorbed to the sealing position of the packaging bag.

[0028] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] like Figures 1 to 8 As shown, the bean curd packaging sealing device of the present invention includes a workbench 1, a bag conveying mechanism 2, a clamping mechanism 3, a mouth-supporting mechanism 4, a feeding mechanism 5, a sealing mechanism 6, a guiding mechanism 7, and a conveying mechanism 8. The bag conveying mechanism 2, the clamping mechanism 3, the mouth-supporting mechanism 4, the feeding mechanism 5, the sealing mechanism 6, the guiding mechanism 7, and the conveying mechanism 8 are all connected to the workbench 1. The bag conveying mechanism 2 is used to sequentially convey multiple packaging bags to the clamping mechanism 3. The clamping mechanism 3 can sequentially clamp multiple packaging bags and drive the packaging bags along a circular path. The trajectory movement mechanism 4 can sequentially open the openings of multiple packaging bags, the feeding mechanism 5 can put the dried bean curd into the opened packaging bags, the sealing mechanism 6 can vacuum the packaging bags containing dried bean curd and seal them, the guiding mechanism 7 can squeeze and guide the packaging bags containing dried bean curd, extending the movement path of the juice during vacuuming, thereby preventing the juice from being absorbed to the sealing position of the packaging bags, thus avoiding affecting the sealing effect of the packaging bags, and the conveying mechanism 8 can transport the sealed packaging bags.

[0030] Continue to refer to Figures 1 to 8As shown, the guiding mechanism 7 includes a lifting part 71, a mounting frame 72, a clamping member 73, a pushing member 74, and a guiding member 75. The lifting part 71 is connected to the top of the workbench 1 and is a cylinder with its telescopic end facing upwards. The mounting frame 72 is connected to the telescopic end of the lifting part 71. The clamping member 73, the pushing member 74, and the guiding member 75 are all connected to the mounting frame 72. The clamping member 73 can clamp the bottom of the packaging bag. The pushing member 74 can tilt and push the dried bean curd inside the packaging bag so that the top dried bean curd is away from the sealing position of the packaging bag. When the packaging bag is vacuumed, the guiding member 75 can form a curved path for air and juice to flow and extend the path for juice to flow, so as to prevent juice from being absorbed to the sealing position of the packaging bag. When the pushing member 74 pushes the dried bean curd, it can make the top dried bean curd away from the curved path for air and juice to flow, further preventing juice from being absorbed to the sealing position of the packaging bag.

[0031] Continue to refer to Figures 1 to 8 As shown, the clamping component 73 includes a drive unit 731, a channel 732, a clamping part 733, and a connecting pipe 734. There are two channels 732. The drive unit 731 and the two channels 732 are connected to the mounting bracket 72. There are two sets of clamping parts 733, with two clamping parts 733 in each set. The two sets of clamping parts 733 are respectively inserted into the two channels 732. The drive unit 731 is an air pump. The drive unit 731 is connected to the two channels 732 by the connecting pipe 734, which is a three-pronged pipe. When the drive unit 731 is started, air is supplied to the two channels 732 through the connecting pipe 734, so that the two clamping parts 733 in the same set move closer to each other, thereby clamping the bottom of the packaging bag.

[0032] Continue to refer to Figures 1 to 8 As shown, the mounting bracket 72 has through slots 721 on both the left and right sides. The pusher 74 is configured in two sets, which are respectively connected to the left and right sides of the mounting bracket 72. The pusher 74 includes a second drive part 741, a second channel 742, a second connecting pipe 743, a moving part 744, and a pushing part 745. The second drive part 741 is connected to the mounting bracket 72. The second channel 742 is connected to the inside of the through slot 721. The moving part 744 is inserted into the second channel 742 and is slidably connected in the through slot 721. The pushing part 745 is connected to the moving part 744. The pushing parts 745 on both sets of pushers 74 are located inside the mounting bracket 72. The second drive part 741 is an air pump. The second connecting pipe 743 is connected between the second drive part 741 and the second channel 742.

[0033] Activate the drive unit 741 on the two sets of pushers 74 to deliver air into the channel 742 through the connecting pipe 743, thereby pushing the moving part 744 to tilt downwards, causing the two pushers 745 to tilt downwards, thereby pushing the dried bean curd at the top of the packaging bag to tilt and move away from the sealed position of the packaging bag.

[0034] Continue to refer to Figures 1 to 8 As shown, the guide member 75 is configured in two sets, which are respectively connected to the left and right sides of the mounting frame 72. The guide member 75 includes a channel 3 751, a magnetic block 1 752, a magnetic block 2 753, a telescopic part 754, a connecting pipe 3 755, and a guide part 756. The channel 3 751 is connected to the mounting frame 72, the magnetic block 1 752 is connected to the moving part 744, the magnetic block 2 753 is connected to the channel 2 742, the telescopic part 754 is inserted into the channel 3 751, and the connecting pipe 3 755 is connected between the channel 2 742 and the channel 3 751. Before the moving part 744 drives the pushing part 745 to complete its movement, the moving part 744 can block one end of the connecting pipe 3 755. After the moving part 744 drives the pushing part 745 to move, it stops moving. The connecting pipe 755 connects the channel 2 742 and the channel 3 751. The guide part 756 is connected to the telescopic part 754. The guide parts 756 on the two sets of guide members 75 can approach each other and tightly clamp the packaging bag. The guide part 756 is provided with a guide groove 7561. Through the guide groove 7561 on the two guide parts 756, a curved path for air and juice to flow can be formed inside the packaging bag. The air and juice below the guide part 756 can only flow through this curved path, thereby extending the juice flow path and preventing the juice from being absorbed to the sealing position of the packaging bag.

[0035] After the pusher 74 pushes the dried bean curd at the top of the packaging bag, the moving part 744 and the pusher 74 stop moving. At this time, the magnetic block 1 752 and the magnetic block 2 753 are magnetically attracted, and the moving part 744 no longer seals the connecting pipe 3 755, so that the channel 2 742 and the channel 3 751 are connected through the connecting pipe 3 755. The driving part 2 741 continues to supply air into the channel 2 742 through the connecting pipe 2 743, and can supply air into the channel 3 751 through the connecting pipe 3 755, thereby pushing... The telescopic part 754 moves and drives the guide part 756 to approach the packaging bag. The guide part 756 on the two pushers 74 tightly clamps the packaging bag. At this time, the guide groove 7561 on the two guide parts 756 forms a curved path for air and juice to flow inside the packaging bag. When the sealing mechanism 6 evacuates the packaging bag, the air inside the packaging is first discharged through the curved path, and then the juice flows in the curved path to extend the path of juice flow and prevent the juice from being absorbed to the sealing position of the packaging bag.

[0036] Working principle:

[0037] Start the bag conveying mechanism 2 to sequentially transport multiple packaging bags to the clamping mechanism 3.

[0038] Start the clamping mechanism 3 to clamp multiple packaging bags in sequence and move the packaging bags along a circular trajectory, so that the multiple packaging bags move to the opening mechanism 4 in sequence.

[0039] Activate the opening support mechanism 4 to open the bag opening.

[0040] Start the feeding mechanism 5 to put the dried bean curd into the packaging bag.

[0041] The lifting unit 71 is activated, which moves the mounting frame 72 up to the bottom of the packaging bag containing dried bean curd. The drive unit 731 is activated, and air is supplied to the two channels 732 through the connecting pipe 734, so that the two clamping parts 733 of the same group move closer to each other, thereby clamping the bottom of the packaging bag.

[0042] Activate the drive unit 741 on the two sets of pushers 74 to deliver air into the channel 742 through the connecting pipe 743, thereby pushing the moving part 744 to tilt downwards, causing the two pushers 745 to tilt downwards, thereby pushing the dried bean curd at the top of the packaging bag to tilt and move away from the sealed position of the packaging bag.

[0043] After the pusher 74 pushes the tofu at the top of the packaging bag, the moving part 744 and the pusher 74 stop moving. At this time, the magnetic block 1 752 and the magnetic block 2 753 are magnetically attracted, and the moving part 744 no longer seals the connecting pipe 3 755, so that the channel 2 742 and the channel 3 751 are connected through the connecting pipe 3 755. The driving part 2 741 continues to deliver air into the channel 2 742 through the connecting pipe 2 743, and can deliver air into the channel 3 751 through the connecting pipe 3 755, thereby pushing the telescopic part 754 to move and driving the guide part 756 to approach the packaging bag. The guide part 756 on the two pushers 74 tightly clamps the packaging bag. At this time, the guide groove 7561 on the two guide parts 756 forms a curved path for air and juice to flow inside the packaging bag. When the sealing mechanism 6 evacuates the packaging bag, the air inside the packaging first passes through the curved path to be discharged, and then the juice flows in the curved path to extend the path of juice flow.

[0044] The sealing mechanism 6 is activated to vacuum and seal the packaging bag, and then the sealed packaging bag is placed onto the conveying mechanism 8, which transports the sealed packaging bag.

[0045] After the guide mechanism 7 is used, the second drive unit 741 is activated, and air is evacuated from the inside of the second channel 742 through the second connecting pipe 743. At this time, the first magnetic block 752 on the moving part 744 is magnetically attracted to the second magnetic block 753 in the second channel 742, so that the air in the third channel 751 enters the second channel 742 through the third connecting pipe 755 and is extracted by the second connecting pipe 743. After the telescopic part 754 is reset, the air in the third channel 751 can no longer be extracted, so that the negative pressure in the second channel 742 increases, thereby pulling the moving part 744 to reset and separating the first magnetic block 752 and the second magnetic block 753 until the moving part 744 drives the pushing part 745 to be fully reset. At the same time, the first drive unit 731 is activated, and air is evacuated from the inside of the first channel 732 through the first connecting pipe 734, thereby driving the two clamping parts 733 of each group to move away from each other, so as to loosen the sealed packaging bag.
