Description

Technical Field

[0001] The present application relates to the technical field of dried bean curd production equipment, and in particular to a dried bean curd packaging device and packaging method. Background Art

[0002] Dried tofu is the abbreviation of dried bean curd, one of China's traditional soy products and a processed product of tofu. After processing, dried tofu needs to be vacuum packed for subsequent transportation.

[0003] For example, the Chinese patent document with the announcement number CN103496463B discloses a bag-making and bag-feeding type fully automatic packaging machine, including a workbench, a bag-loading device, a printing device, a bag-opening device, a material-dropping device, a sealing device and an active motor. It also includes an automatic bag-making machine, which is provided with an automatic bag-making machine, and the bag-making process is completed through film pulling, horizontal sealing, cutting and other processes, and the finished finished bags are automatically bagged to the bag-feeding type automatic packaging machine, and then the opening of the finished bag is opened by the bag-opening device, and the material-dropping device is moved vertically into the opened packaging bag, and then the food is loaded into the packaging bag by the material-dropping device, and finally the packaging bag is sealed by the sealing device. In addition, in the food production process, after the food is loaded into the packaging bag, the next station needs to extend the moving rod into the packaging bag in the vertical direction to push the food, so as to ensure that the air in the packaging bag is discharged as much as possible, thereby reducing the oxidation effect of oxygen on the food and extending its shelf life.

[0004] In the above-mentioned related technologies, when packaging foods with juice, such as dried tofu, since the dried tofu contains a small amount of juice and oil, after the dried tofu in the blanking device enters the packaging bag, the end of the blanking device will come into contact with the juice and oil. When the blanking device moves in the opposite direction, the juice and oil on the end will come into contact with the opening of the packaging bag, and then the juice will adhere to the opening of the inner wall of the packaging bag, affecting the subsequent sealing and the aesthetics of the entire packaging; at the same time, since the moving rod needs to be moved into the packaging bag to squeeze the food, it needs to be extended out of the packaging bag after the extrusion is completed, but the moving rod extended into the packaging bag will come into contact with the juice. During the long-term processing, the moving rod will be contaminated with the dried tofu, affecting the quality of the food. Summary of the invention

[0005] The present application provides a dried tofu packaging device and a packaging method, aiming to solve the problem of juice being stained at the opening of the packaging bag in the related art.

[0006] First aspect:

[0009] By adopting the above technical scheme, when the dried tofu needs to be put into the packaging bag, the upper hopper drives the installation frame to move, so that the installation frame can be extended from the opening of the packaging bag into the packaging bag, and the two sealing plates can be rotated in opposite directions. At this time, the opening at the lower end of the installation frame is opened, and the dried tofu in the lower hopper will fall into the packaging bag, and then the lower pressure plate is rotated to squeeze the dried tofu in the packaging bag, thereby reducing the air in the dried tofu. Finally, when the upper hopper drives the installation frame to move in the opposite direction, the lower pressure plate is rotated into the installation frame, and the two sealing plates are rotated in the opposite direction at the same time. Finally, the sealing plate blocks the opening of the installation frame to reduce the pollution caused by leakage of the lower pressure plate.

[0013] By adopting the above technical solution, when the first rotating part and the second rotating part move away from each other, the supporting assembly no longer supports the sealing plate, and then drives the sealing plate to rotate under the action of the torsion spring, thereby facilitating the dried tofu in the upper hopper to fall into the packaging bag through the mounting frame; then when the first rotating part and the second rotating part approach each other, the supporting assembly will drive the two sealing plates to approach each other, and when the first rotating part and the second rotating part abut against each other, the end faces of the two sealing plates also abut against each other, thereby sealing the opening of the mounting frame.

[0014] Optionally, the support assembly includes a connecting rod fixed on the sealing shaft, a support block slidably connected to the first rotating part, a support rod fixed on the support block, and a pushing rod fixed on the second rotating part, one end of the support block abuts against the connecting rod; the support rod includes a vertical part fixed on the support block and a horizontal part fixed on the vertical part, an inclined surface is provided on the horizontal part, and a pushing surface is provided at one end of the pushing rod close to the support rod, the pushing surface is used to abut against the inclined surface.

[0015] By adopting the above technical solution, when the first rotating part and the second rotating part move away from each other, the pushing rod and the support rod are no longer in contact, and under the action of the torsion spring, the sealing plate is pushed to rotate, which is convenient for material unloading. After the material unloading is completed, the first rotating part and the second rotating part approach each other, and the pushing surface on the pushing rod will contact the inclined surface, which will gradually push the support rod to move. During the movement of the support rod, the support block will be pushed to move, and the support block will push the connecting rod and the sealing shaft to rotate, and finally the opening of the installation frame will be sealed.

[0016] Optionally, an adjustment component is provided on both the first rotating part and the second rotating part, the adjustment component is used to adjust the position of the lower pressure plate, and the pushing component is arranged on the adjustment component; the adjustment component includes two adjustment plates slidably connected to the first rotating part, an adjustment rod fixed on the adjustment plate and a connecting plate for connecting the two adjustment rods, an adjustment shaft is fixedly installed on the lower pressure plate, the adjustment shaft is rotatably connected to the adjustment plate, a waist-shaped groove is provided on the adjustment plate, a fixing bolt is threadedly connected to the first rotating part, and the fixing bolt passes through the waist-shaped groove and is threadedly connected to the first rotating part.

[0017] Optionally, the pushing assembly includes a pushing gear fixedly mounted on the adjusting shaft and a pushing rack slidably connected to the adjusting plate, and the pushing rack is meshed with the pushing gear.

[0018] By adopting the above technical solution, the gear can be driven to rotate by pushing the rack to move, and finally the lower pressure plate can be driven to rotate.

At this time, the lower pressure plate is in the mounting frame, and the sealing plate can reduce the contamination of the lower pressure plate.

[0028] In summary, this application has the following beneficial effects:

[0029] After the packaging is completed, the sealing plate rotates into the first rotating part to seal the opening of the mounting frame. At this time, the lower pressure plate is in the mounting frame. The sealing plate can reduce the contamination of the lower pressure plate. In addition, in the process of loading dried tofu, the unfolded sealing plate will contact the juice in the dried tofu. When the first rotating part and the second rotating part are close to each other, the sealing plate stained with juice will rotate into the mounting frame. Then, when the lower hopper moves in the opposite direction, the sealing plate will not contact the packaging bag, which can reduce the adhesion of juice to the opening of the packaging bag.

[0039] The following combination Figure 1-Figure 8 This application is described in further detail.

[0040] First aspect:

[0041] The present application embodiment discloses a dried bean curd packaging device. Figures 1 to 6A dried bean curd packaging device comprises a frame 01, a packaging bag loading assembly 02 arranged on the frame 01, a clamping assembly 03, a bag-supporting assembly 04, a dried bean curd loading assembly 1 and a sealing assembly 05. The packaging bag loading assembly 02 is used to transfer the packaging bag to the clamping assembly 03, and then the packaging bag is opened by the bag-supporting assembly 04. The dried bean curd loading assembly 1 moves toward the opening of the packaging bag so that a part of the dried bean curd loading assembly 1 is in the packaging bag, and then the dried bean curd is put into the packaging bag; after the dried bean curd enters the packaging bag, the dried bean curd loading assembly 1 moves toward the opening of the packaging bag, and finally the packaging bag is sealed by the sealing assembly 05. The packaging bag loading assembly 02, the clamping assembly 03, the bag-supporting assembly 04, the dried bean curd loading assembly 1 and the sealing assembly 05 belong to the prior art. In this embodiment, the specific structure and working principle of the packaging bag loading assembly 02, the clamping assembly 03, the bag-supporting assembly 04, the dried bean curd loading assembly 1 and the sealing assembly 05 are not described in detail. In addition, the dried bean curd feeding assembly 1 can deliver a quantitative amount of dried bean curd into the packaging bag each time, and it belongs to the prior art and will not be described in detail here.

[0042] Reference Figures 1 to 4 The tofu feeding assembly 1 includes a feeding hopper 11 and a mounting frame 12 arranged on the upper hopper 11. The upper hopper 11 is slidably connected to the bracket. The mounting frame 12 has a conical structure, and the horizontal cross-section of the mounting frame 12 gradually decreases in the direction away from the upper hopper 11; two blocking plates 2 are arranged at one end of the mounting frame 12 away from the upper hopper 11, and the two blocking plates 2 are rotatably connected to the mounting frame 12. In addition, a lower pressure plate 21 is rotatably connected to the inner wall of the installation frame 12. When the dried tofu needs to be loaded into the packaging bag, the upper hopper 11 drives the installation frame 12 to move, so that the installation frame 12 can be extended into the packaging bag from the opening of the packaging bag, and the two sealing plates 2 are rotated in opposite directions. At this time, the opening at the lower end of the installation frame 12 is opened, and the dried tofu in the lower hopper will fall into the packaging bag, and then the lower pressure plate 21 is rotated to squeeze the dried tofu in the packaging bag, thereby reducing the air in the dried tofu. Finally, when the upper hopper 11 drives the installation frame 12 to move in the opposite direction, the lower pressure plate 21 is rotated into the installation frame 12, and the two sealing plates 2 are rotated in the opposite direction. Finally, the sealing plate 2 blocks the opening of the installation frame 12 to reduce the leakage of the lower pressure plate 21 and the pollution.

[0043] Reference Figures 1 to 4The mounting frame 12 includes a first rotating part 121 and a second rotating part 122. The first rotating part 121 and the second rotating part 122 are both fixedly mounted with a rotating shaft 22. The rotating shaft 22 is rotatably connected to the upper hopper 11. When the first rotating part 121 and the second rotating part 122 are in contact, the cross section of the end away from the upper hopper 11 is the smallest, which facilitates the movement of the mounting frame 12 into the packaging bag. At the same time, a control component 3 is provided on the upper hopper 11. The control component 3 is used to drive the first rotating part 121 and the second rotating part 122 to move away from each other. At this time, the first rotating part 121 and the second rotating part 122 support the opening of the packaging bag, further enlarging the opening of the packaging bag. When the first rotating part 121 and the second rotating part 122 rotate at the same time, the blocking plate 2 also rotates, and finally facilitates the dried tofu to fall into the packaging bag.

[0044] Reference Figures 1 to 4 The control assembly 3 includes a control block 31 slidably connected to the upper hopper 11, a sliding rod 32 hinged on the control block 31 and a mounting rod 33 slidably connected to the sliding rod 32, and the end of the mounting rod 33 away from the control block 31 is fixedly connected to the rotating shaft 22. Since two rotating shafts 22 are provided, two sliding rods 32 and two mounting rods 33 are also provided on the control block 31, so that when the control block 31 moves, the two blocking plates 2 can be driven to move in opposite directions; in order to facilitate the movement of the control block 31, a control cylinder is provided on the upper hopper 11, the piston rod of the control cylinder is fixed on the control block 31, and the cylinder body is fixed on the upper hopper 11.

[0045] Reference Figures 1 to 8 In order to facilitate the rotation of the blocking plate 2, a blocking shaft 23 is fixedly installed on the blocking plate 2, and the blocking shaft 23 is rotatably connected to the mounting frame 12, and a control member 24 for driving the blocking plate 2 to rotate is provided on the mounting frame 12. The two blocking plates 2 in this embodiment can block the openings of the first rotating part 121 and the second rotating part 122 that abut against each other, and then when no dried tofu is added to the packaging bag, the opening of the mounting frame 12 is in a blocked state, thereby reducing the contamination of the dried tofu in the mounting frame 12 and the lower pressing plate 21.

[0046] Reference Figures 1 to 8The control member 24 is configured as a torsion spring, one end of which is fixed on the blocking shaft 23, and the other end is fixed on the mounting frame 12. At the same time, a support assembly 4 is provided on the mounting frame 12, and the support assembly 4 is used to keep the blocking plate 2 in a horizontal state and to block the opening of the mounting frame 12. When the first rotating part 121 and the second rotating part 122 move away from each other, the support assembly 4 no longer supports the blocking plate 2, and then drives the blocking plate 2 to rotate under the action of the torsion spring, thereby facilitating the dried tofu in the upper hopper 11 to fall into the packaging bag through the mounting frame 12; then when the first rotating part 121 and the second rotating part 122 approach each other, the support assembly 4 will drive the two blocking plates 2 to approach each other, and when the first rotating part 121 and the second rotating part 122 abut, the end faces of the two blocking plates 2 also abut against each other, thereby blocking the opening of the mounting frame 12.

[0047] Reference Figures 1 to 8 Since two blocking plates 2 are provided, two support assemblies 4 are also provided, and the two support assemblies 4 are provided on opposite sides of the mounting frame 12, in this embodiment, only the support assembly 4 on the first rotating portion 121 is described; for details, refer to Figure 7 The support assembly 4 includes a connecting rod 41 fixed on the blocking shaft 23, a support block 42 slidably connected to the first rotating part 121, a support rod 43 fixed on the support block 42, and a pushing rod 44 fixed on the second rotating part 122. One end of the support block 42 abuts against the connecting rod 41. An arc groove 25 is provided on the first rotating part 121. A sliding block is slidably connected in the arc groove 25. The arc block is fixed on the support block 42. Through the arrangement of the arc groove 25 and the arc block, the support block 42 can be made more stable when moving.

[0048] Reference Figure 7 The support rod 43 includes a vertical portion 431 fixed on the support block 42 and a horizontal portion 432 fixed on the vertical portion 431. The horizontal portion 432 is provided with an inclined surface 26, and a pushing surface 27 is provided at one end of the push rod 44 close to the support rod 43. The pushing surface 27 is used to abut against the inclined surface 26. When the first rotating portion 121 and the second rotating portion 122 are in an abutting state, the pushing surface 27 on the push rod 44 abuts against the inclined surface 26. At this time, the support block 42 is at the highest point, and then the support block 42 supports the connecting rod 41, and the sealing plate 2 is in the installation frame 12.

[0049] When the first rotating part 121 and the second rotating part 122 are away from each other, the push rod 44 and the support rod 43 are no longer in contact. At this time, under the action of the torsion spring, the blocking plate 2 is pushed to rotate. During the rotation of the blocking plate 2, the blocking shaft 23 and the connecting rod 41 are driven to rotate. The connecting rod 41 will push the support block 42 to slide on the first rotating part 121. When the blocking plate 2 is completely rotated out, the support block 42 is at the lowest point. After the unloading is completed, the first rotating part 121 and the second rotating part 122 are close to each other. At this time, the push surface 27 on the push rod 44 will contact the inclined surface 26, and will gradually push the support rod 43 to move. During the movement of the support rod 43, the support block 42 will be pushed to move. The support block 42 pushes the connecting rod 41 and the blocking shaft 23 to rotate, and finally the installation frame 12 is blocked. Since the arc block is slidably connected in the arc groove 25, the support block 42 can always slide in the horizontal direction during the movement, and then it will be more stable when pushing the connecting rod 41 to rotate.

Since the adjustment components 5 on the first rotating part 121 and the second rotating part 122 have the same structure, in this embodiment, only the adjustment component 5 and the pushing component 6 on the first rotating part 121 are described in detail.

[0051] Reference Figures 1 to 8 The adjusting assembly 5 includes two adjusting plates 51 slidably connected to the first connecting part, an adjusting rod 52 fixed on the adjusting plate 51 and a connecting plate 53 for connecting the two adjusting rods 52.

In this embodiment, an adjusting shaft 7 is fixedly installed on the lower pressing plate 21, and the adjusting shaft 7 is rotatably connected to the adjusting plate 51. In addition, a waist-shaped groove 71 is opened on the adjusting plate 51, and a fixing bolt 72 is threadedly connected to the first rotating part 121. The fixing bolt 72 passes through the waist-shaped groove 71 and is threadedly connected to the first rotating part 121, thereby fixing the adjusting plate 51 on the first rotating part 121. Under the action of the waist-shaped groove 71, it is convenient to adjust the position of the connecting plate 53, and then it is convenient to adjust the position of the adjusting plate 51, so that the lower pressing plate 21 can squeeze the dried tofu in the packaging bags of different depths.

[0052] Reference Figures 1 to 8The pushing assembly 6 includes a pushing gear 61 fixedly mounted on the adjusting shaft 7 and a pushing rack 62 slidably connected to the adjusting plate 51. The pushing rack 62 is meshed with the pushing gear 61, and then the pushing rack 62 is moved to drive the pushing gear 61 to rotate, and finally drive the lower pressing plate 21 to rotate. In this embodiment, a mounting groove is provided on the inner wall of the first rotating part 121. When the lower pressing plate 21 is in the mounting groove, the lower pressing plate 21 is flush with the inner wall of the first rotating part 121. In order to facilitate the movement of the pushing rack 62, a connecting rod is fixedly mounted on the pushing rack 62, and the connecting rod extends out of the first rotating part 121. A pushing cylinder is provided at one end of the connecting rod, and the pushing cylinder is fixed on the first rotating part 121. The pushing rack 62 is driven to move by the pushing cylinder, and then the lower pressing plate 21 is driven to rotate, and finally the purpose of conveniently squeezing the dried tofu by rotating the lower pressing plate 21 is achieved.

[0053] The implementation principle of the dried bean curd packaging device of the embodiment of the present application is as follows: after the dried bean curd falls into the packaging bag, the first rotating part 121 and the second rotating part 122 are in an open state, and then the push cylinder drives the push rack 62 to move, and the push rack 62 and the push gear 61 drive the lower pressing plate 21 to rotate, and the dried bean curd in the packaging bag is squeezed by the rotation of the lower pressing plate 21. After the squeezing is completed, the push cylinder drives the lower pressing plate 21 to rotate in the opposite direction, and the control component 3 drives the first rotating part 121 and the second rotating part 122 to approach each other. At the same time, under the action of the support component 4 , so that the blocking plate 2 rotates into the first rotating part 121 to block the opening of the installation frame 12. At this time, the lower pressing plate 21 is in the installation frame 12. The blocking plate 2 can reduce the contamination of the lower pressing plate 21. In addition, in the process of loading dried tofu, since the unfolded blocking plate 2 will contact the juice in the dried tofu, when the first rotating part 121 and the second rotating part 122 are close to each other, the blocking plate 2 stained with juice will rotate into the installation frame 12, and then when the lower hopper moves in the opposite direction, the blocking plate 2 does not contact the packaging bag, which can reduce the adhesion of juice to the opening of the packaging bag.
