The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0027] like Figures 1 to 8 As shown, the dried bean curd packaging and sealing device of the present invention comprises a workbench 1, a bag conveying mechanism 2, a clamping mechanism 3, a mouth-opening mechanism 4, a material-discharging mechanism 5, a sealing mechanism 6, a guiding mechanism 7 and a discharging mechanism 8. The bag conveying mechanism 2, the clamping mechanism 3, the mouth-opening mechanism 4, the material-discharging mechanism 5, the sealing mechanism 6, the guiding mechanism 7 and the discharging mechanism 8 are all connected to the workbench 1. The bag conveying mechanism 2 is used to convey a plurality of packaging bags to the clamping mechanism 3 in sequence. The clamping mechanism 3 can clamp a plurality of packaging bags in sequence and drive the packaging bags to move in a circular motion. The opening mechanism 4 can open the bag openings of multiple packaging bags in turn, the feeding mechanism 5 can put the dried bean curd into the packaging bag with the opened bag openings, the sealing mechanism 6 can vacuum the packaging bag containing the dried bean curd and seal it, the guiding mechanism 7 can squeeze and guide the packaging bag containing the dried bean curd, and extend the movement path of the juice during vacuuming, so as to avoid the juice being absorbed into the sealing position of the packaging bag, thereby avoiding affecting the sealing effect of the packaging bag, and the delivery mechanism 8 can transport the sealed packaging bag.

[0028] Continue to refer Figures 1 to 8As shown, the guide 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. The lifting part 71 is a cylinder with the telescopic end facing upward. 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 in the packaging bag to make the dried bean curd at the top away from the sealing position of the packaging bag. The guiding member 75 can form a curved path for air and juice to flow when the packaging bag is vacuumed, and extend the path for the juice to flow to avoid the juice being adsorbed to the sealing position of the packaging bag. When the pushing member 74 pushes the dried bean curd, it can make the dried bean curd at the top away from the curved path for air and juice to flow, further avoiding the juice being adsorbed to the sealing position of the packaging bag.

[0029] Continue to refer Figures 1 to 8 As shown, the clamping member 73 includes a driving part 731, a channel 732, a clamping part 733 and a connecting pipe 734. There are two channels 732. The driving part 731 and the two channels 732 are connected to the mounting frame 72. There are two groups of clamping parts 733. Each group of clamping parts 733 has two clamping parts. The two groups of clamping parts 733 are respectively plugged into the two channels 732. The driving part 731 is an air pump. The connecting pipe 734 is connected between the driving part 731 and the two channels 732. The connecting pipe 734 is a three-headed pipe. The driving part 731 is started to transport air into the two channels 732 through the connecting pipe 734, so that the two clamping parts 733 in the same group are close to each other, thereby clamping the bottom of the packaging bag.

[0030] Continue to refer Figures 1 to 8 As shown, through grooves 721 are provided on the left and right sides of the mounting frame 72, and the pushing members 74 are provided in two groups. The two groups of pushing members 74 are respectively connected to the left and right sides of the mounting frame 72, and the pushing members 74 include a second driving part 741, a second channel 742, a second connecting pipe 743, a moving part 744 and a pushing part 745. The second driving part 741 is connected to the mounting frame 72, the second channel 742 is connected to the inner side of the through groove 721, the moving part 744 is inserted into the second channel 742, and the moving part 744 is slidably connected in the through groove 721, and the pushing part 745 is connected to the moving part 744. The pushing parts 745 on the two groups of pushing members 74 are both located on the inner side of the mounting frame 72, the second driving part 741 is an air pump, and the second connecting pipe 743 is connected between the second driving part 741 and the second channel 742.

[0031] The second driving part 741 on the two sets of pushing members 74 is started to make the connecting pipe 743 convey air into the second channel 742, thereby pushing the moving part 744 to move downwardly, so that the two pushing parts 745 move downwardly, thereby pushing the dried tofu at the top of the packaging bag to move obliquely, so that the dried tofu at the top is away from the sealing position of the packaging bag.

[0032] Continue to refer Figures 1 to 8 As shown, the guide member 75 is provided in two groups, and the two groups of guide members 75 are respectively connected to the left and right sides of the mounting frame 72. The guide member 75 includes a channel three 751, a magnetic block 1 752, a magnetic block 2 753, a telescopic portion 754, a connecting pipe three 755 and a guide portion 756. The channel three 751 is connected to the mounting frame 72, the magnetic block 1 752 is connected to the moving portion 744, the magnetic block 2 753 is connected to the channel two 742, the telescopic portion 754 is plugged into the channel three 751, and the connecting pipe three 755 is connected between the channel two 742 and the channel three 751. Before the moving portion 744 drives the pushing portion 745 to move completely, the moving portion 744 can block one end of the connecting pipe three 755 After the moving part 744 drives the pushing part 745 to move, it will no longer move. The channel 2 742 and the channel 3 751 can be connected through the connecting pipe 3 755. The guide part 756 is connected to the telescopic part 754. The guide parts 756 on the two groups of guide members 75 can approach each other and tightly clamp the packaging bag. The guide parts 756 are provided with guide grooves 7561. Through the guide grooves 7561 on the two guide parts 756, a curved path for the flow of air and juice can be formed in the packaging bag, and the air and juice below the guide part 756 can only flow along the curved path, thereby extending the path of the juice flow and preventing the juice from being adsorbed to the sealing position of the packaging bag.

[0033] After the pusher 74 pushes the dried bean curd on the top of the packaging bag, the moving part 744 and the pusher 74 finish moving and 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 transport air into the channel 2 742 through the connecting pipe 2 743, and can transport air to the channel 3 751 through the connecting pipe 3 755, thereby pushing the package. The telescopic portion 754 moves and drives the guide portion 756 to approach the packaging bag, and the packaging bag is tightly clamped by the guide portions 756 on the two push members 74. At this time, a curved path for the flow of air and juice is formed in the packaging bag through the guide grooves 7561 on the two guide portions 756, so that when the sealing mechanism 6 vacuums the packaging bag, the air in the package is first discharged through the curved path, and then the juice flows in the curved path to extend the flow path of the juice and prevent the juice from being adsorbed to the sealing position of the packaging bag.

[0034] Working principle: The bag conveying mechanism 2 is started to convey the multiple packaging bags to the clamping mechanism 3 in sequence.

[0035] The clamping mechanism 3 is started to clamp a plurality of packaging bags in sequence, and drives the packaging bags to move along a circular track, and moves the plurality of packaging bags to the opening mechanism 4 in sequence.

[0036] The opening mechanism 4 is started to open the bag opening of the packaging bag.

[0037] The feeding mechanism 5 is started to put the dried bean curd into the packaging bag.

[0038] The lifting part 71 is started to drive the mounting frame 72 to move up to the bottom of the packaging bag containing dried tofu, and the driving part 731 is started to transport air into the two channels 732 through the connecting pipe 734, so that the two clamping parts 733 of the same group are close to each other, thereby clamping the bottom of the packaging bag.

[0039] The second driving part 741 on the two sets of pushing members 74 is started to make the connecting pipe 743 convey air into the second channel 742, thereby pushing the moving part 744 to move downwardly, so that the two pushing parts 745 move downwardly, thereby pushing the dried tofu at the top of the packaging bag to move obliquely, so that the dried tofu at the top is away from the sealing position of the packaging bag.

[0040] After the pushing member 74 pushes the dried tofu on the top of the packaging bag, the moving part 744 and the pushing member 74 have finished moving and no longer move. 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 transport air into the channel 2 742 through the connecting pipe 2 743, and can transport air to 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, and the packaging bag is tightly clamped by the guide parts 756 on the two pushing members 74. At this time, a curved path for air and juice to flow is formed in the packaging bag through the guide grooves 7561 on the two guide parts 756, so that when the sealing mechanism 6 vacuums the packaging bag, the air in the package is first discharged through the curved path, and then the juice flows in the curved path to extend the path of the juice flow.

[0041] The sealing mechanism 6 is started to evacuate and seal the packaging bag, and the sealed packaging bag is placed on the discharging mechanism 8, which transports the sealed packaging bag.

[0042] After the use of the guide mechanism 7 is completed, the driving part 2 741 is started to evacuate the inside of the channel 2 742 through the connecting pipe 2 743. At this time, the magnetic block 1 752 on the moving part 744 is magnetically attracted to the magnetic block 2 753 in the channel 2 742, so that the air in the channel 3 751 enters the channel 2 742 through the connecting pipe 3 755 and is extracted by the connecting pipe 2 743. After the telescopic part 754 is reset, the air in the channel 3 751 can no longer be extracted, so that the negative pressure in the channel 2 742 is enhanced, thereby pulling the moving part 744 to reset and separating the magnetic block 1 752 and the magnetic block 2 753 until the moving part 744 drives the pushing part 745 to completely reset. At the same time, the driving part 1 731 is started to evacuate the inside of the channel 1 732 through the connecting pipe 1 734, thereby driving the two clamping parts 733 of each group to move away from each other to loosen the sealed packaging bag.
