Description

Technical Field

[0001] The embodiments of the present disclosure relate to the technical field of bagged food packaging equipment, and in particular, to a filling and sealing equipment for bagged sauce production. Background Art

[0002] In the prior art, many materials are gradually packaged, sealed, stored, and transported in bottles or bags. In particular, materials containing liquids or slurries, such as juicy mustard tubers and various sauce bags, are mostly packaged and transported in material bags. The general operation process is to take the packaging bag, open the packaging bag, fill the packaging bag with materials, seal the packaging bag, and then store it in the warehouse, and deliver it to the place of use. The sealing of the packaging bag plays a vital role in the process.

[0003] In addition, there is a common problem when opening bagged products, that is, the packaging bag is difficult to open, so the edge of the packaging bag is generally processed and a tear is left to facilitate people to quickly open the bagged product through the tear. This processing is also closely related to the sealing of the packaging bag. If the tear is too long, it is easy to cause the sealing of the bagged product to fail. Once the packaging bag is not sealed tightly or cracked, during the storage and transportation process, it will cause the material to seep or flow out, causing material contamination, deterioration, and inedible, resulting in increased costs. At the same time, the seeped or flowed material will also adhere to other problem-free packaging bags, resulting in a large amount of cleaning and washing operations. The adhered packaging bags need to be re-inspected, cleaned, disinfected and other processes, which is time-consuming and labor-intensive.

[0004] At the same time, if the tear produced by processing on the packaging bag is not in the right direction or is offset, it will not help to open the packaging bag. Therefore, it is necessary to improve and optimize the existing technology to improve the sealing effect of the packaging bag. Summary of the invention

[0005] In order to overcome the above-mentioned defects, the embodiments of the present disclosure provide a filling and sealing device for the production of bagged sauces, which solves the problems in the prior art that, during the packaging operation, the packaging bags may be poorly sealed, cracked, or the tearing edge may be too long, resulting in material leakage, increased costs, and product deterioration.

[0025] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0026] like Figure 1 to Figure 8 As shown, it shows a filling and sealing device for producing bagged sauces in one embodiment of the present disclosure.

[0027] In some examples, the filling and sealing equipment includes a frame, a transfer tray, a heat sealing unit, a support, a bag fixing member and a cutting knife; the transfer tray 2 is rotatably set on the frame 1 for transferring the material bag 3; the heat sealing unit 4 is slidably set relative to the frame 1 and is located on one side of the transfer tray 2, the heat sealing unit 4 has a sealing space 6, and the sealing space 6 is used to seal the material bag 3 transferred by the transfer tray 2; the support 23 is set on the frame 1 and is located on the side of the transfer tray 2; the bag fixing member 18 is slidably set relative to the support 23 and is located above the sealing space 6, the bag fixing member 18 has a bag card slot 19 and a knife slot 20 which are perpendicular to each other, and the bag card slot 19 and the knife slot 20 are connected to each other; after the bag fixing member 18 slides, the material bag 3 is inserted into or removed from the bag card slot 19; the cutting knife 16 is slidably set relative to the support 23 and is located on one side of the bag fixing member 18, the sliding directions of the cutting knife 16 and the bag fixing member 18 are perpendicular to each other, and after the cutting knife 16 slides, the cutting knife 16 is inserted into or removed from the knife slot 20.

[0028] For example, Figure 1 to Figure 8 As shown, the filled material bag 3 is fixed on the transfer plate 2, and the transfer plate 2 rotates to transfer the material bag 3 to the sealing space 6 of the heat sealing unit 4, and the heat sealing unit 4 is started to perform thermoplastic sealing on the upper edge of the material bag 3. After the material bag 3 is sealed, it is in a vertical hoisting state, and a sealing belt will be left on the material bag 3; an external force is applied to drive the bag-fixing member 18 to slide downward, and the bag-fixing member 18 will move in the same direction with the cutting knife 16; the bag-fixing member 18 gradually approaches the material bag 3 until the sealing belt of the material bag 3 is stuck in the bag-fixing groove 19 for a distance After separation, the bag fixing member 18 stops sliding, and the cutting knife 16 is located at the side of the material bag 3; then another force is applied to drive the cutting knife 16 to slide in the direction close to the material bag 3, and the cutting knife 16 gradually approaches and is inserted into the knife groove 20, and the cutting knife 16 cuts the material bag 3 in the knife groove 20, leaving a tear at the side edge of the material bag 3, and at the same time will not cause leakage of the product in the material bag 3, so that the later user can open the bagged product through the tear to achieve quick use and consumption, reducing the difficulty of opening for the user.

[0029] The upper edge of the material bag 3 is fixed by means of the bag clamping groove 19 to prevent the material bag 3 from being offset and deformed when the cutting knife 16 cuts the material bag 3, thereby causing the bag cutting operation to fail. The knife groove 20 is used to constrain the trajectory of the cutting knife 16 to ensure the consistency of the bag cutting operation and the bag cutting position, improve the consistency of the product, and ensure that the tearing opening can effectively help people open the packaging bag.

[0030] At the same time, by designing the bag fixing member 18 and the cutting knife 16 above the sealing space 6, the space of the sealing space 6 is fully utilized to reduce the subsequent processing steps. At the same time, the transfer plate 2 clamps the material bag 3 to ensure the consistency of the product state.

[0031] In some examples, the heat sealing unit 4 is refined, and the heat sealing unit 4 includes two heat sealing plates 5 sliding in opposite directions, and the gap between the two heat sealing plates 5 forms a sealing space 6. After the heat sealing plates 5 slide, the size of the sealing space 6 is adjusted; the heat sealing plates 5 are slidably arranged on the support member 23. The heat sealing plates 5 can be selected from the prior art equipment that can perform thermoplastic sealing on the material bag 3 made of plastic material by heating.

[0032] For example, Figure 1~Figure 5 As shown, the transfer plate 2 rotates to transfer the material bag 3 to the sealing space 6, and the two heat sealing plates 5 approach each other and come into squeeze contact with the outer surface at the upper edge of the material bag 3, and then the heat sealing plates 5 are started to heat and seal the material bag 3. After the sealing operation is completed, the two heat sealing plates 5 slide away from each other to restore the gap size of the sealing space 6, which is convenient for the further operation of the bag fixing part 18 and the cutting knife 16 to complete the processing of the tear. At the same time, the size of the sealing space 6 can be adjusted by the sliding heat sealing plate 5, which is suitable for material bags 3 of different thicknesses, ensuring that while completing the sealing operation, the material bag 3 will not be squeezed, excessively thinned, and there is a risk of rupture.

[0033] In some examples, the transmission unit 24 is structurally refined and includes a slide 25, a first rack 26, a second rack 27, a first transmission shaft 28, a second transmission shaft 29, a first transmission gear 30, a fourth transmission gear 31, a third transmission gear 32, a second transmission gear 33 and a third rack 34.

[0034] The slide 25 is arranged on the heat sealing plate 5 near the support 23 side; the first rack 26 is arranged on the slide 25; the second rack 27 is arranged on the slide 25, and the second rack 27 is parallel to the first rack 26 and staggered; the first transmission shaft 28 is rotatably arranged on the support 23; the second transmission shaft 29 is arranged on the support 23, and the second transmission shaft 29 is parallel to the first transmission shaft 28 and staggered; the first transmission gear 30 is rotatably arranged on the first transmission shaft 28 by means of a one-way rotating bearing; the fourth transmission gear 31 is rotatably arranged on the first transmission shaft 28 by means of a one-way rotating bearing, and the fourth transmission gear 31 is The movable gear 31 is spaced apart from the first transmission gear 30; the third transmission gear 32 is arranged on the first transmission shaft 28, and the fourth transmission gear 31 is located between the first transmission gear 30 and the third transmission gear 32; the second transmission gear 33 is rotatably arranged on the second transmission shaft 29, and the second transmission gear 33 is meshed and connected with the fourth transmission gear 31; the third rack 34 is arranged on the solid bag part 18, and the third rack 34 is meshed and connected with the third transmission gear 32; after the sliding member 25 slides, the first transmission gear 30 is meshed with the first rack 26 or the second transmission gear 33 is meshed with the second rack 27.

[0035] For example, Figure 1 to Figure 6As shown, during operation, when the heat sealing unit 4 has completed its operation, the two heat sealing plates 5 move away from each other, the heat sealing plate 5 close to the support 23 is defined as plate A, and the heat sealing plate 5 away from the support 23 is defined as plate B; in this example, the slide 25 is arranged on plate A, and as plate A slides, plate A slides with the slide 25, the first rack 26 and the second rack 27 towards the direction close to the support 23 at the same time, at which time the first rack 26 first meshes with the first transmission gear 30, and with the sliding of the first rack 26, the first transmission gear 30 is driven to rotate, and the first transmission gear 30 is installed on the first transmission shaft 28 with the help of a one-way rotating bearing in the prior art, at which time the first The transmission gear 30 will drive the first transmission shaft 28 to rotate synchronously, and through the rotation of the first transmission shaft 28, drive the third transmission gear 32 to rotate in the same direction. At this time, the rotation direction of the first transmission shaft 28 is defined as forward rotation; at this time, the fourth transmission gear 31 is installed on the first transmission shaft 28 with the help of a one-way rotating bearing in the prior art, and the forward rotation of the first transmission shaft 28 will not drive the fourth transmission gear 31 to rotate; the third transmission gear 32 drives the meshing third rack 34 to slide downward, and the third rack 34 drives the bag fixing part 18 to slide downward, and the bag fixing part 18 and the cutting knife 16 slide synchronously to the edge position close to the material bag 3 and prepare for bag cutting operation.

[0036] As the plate A continues to slide, the first rack 26 separates from the first transmission gear 30; at this time, the second rack 27 and the second transmission gear 33 are in a separated state, and an external force is applied to drive the cutter 16 to quickly complete the bag cutting operation and withdraw the cutter 16 from the material bag 3.

[0037] Then the second rack 27 is meshed with the second transmission gear 33. With the sliding of the slider 25, the second rack 27 drives the second transmission gear 33 to rotate on the second transmission shaft 29. The rotating second transmission gear 33 drives the meshed fourth transmission gear 31 to rotate. The fourth transmission gear 31 is installed on the first transmission shaft 28 with the help of a one-way rotating bearing in the prior art.

[0038] The fourth transmission gear 31 drives the first transmission shaft 28 to rotate, and the rotation direction is opposite to the forward rotation, which is defined as reverse rotation; the reversely rotating first transmission shaft 28 drives the third transmission gear 32 to rotate in the reverse direction, and the third transmission gear 32 drives the meshing third rack 34 to slide upward, and the third rack 34 drives the bag-fixing member 18 to slide upward until the second rack 27 is separated from the second transmission gear 33, and the bag-fixing member 18 stops sliding upward and is separated from the material bag 3. The bag-fixing member 18 and the cutting knife 16 slide in the same direction away from the material bag 3 to wait for the next bag cutting operation.

[0039] When the heat sealing unit 4 is ready to seal a new material bag 3 again, the plate A moves away from the support member 23 and gradually approaches the new material bag 3; at this time, the second rack 27 on the slide 25 is first meshed and connected with the second transmission gear 33, and the first rack 26 and the first transmission gear 30 are in a separated state; the rotation of the second transmission gear 33 drives the meshed fourth transmission gear 31 to rotate in the forward rotation direction, and the fourth transmission gear 31 idles on the first transmission shaft 28, and the first transmission shaft 28 and the third transmission gear 32 do not rotate, that is, the third rack 34 and the bag-fixing member 18 do not slide up and down, thereby preventing the bag-fixing member 18 and the cutting knife 16 from entering the sealing space 6, and avoiding problems such as extrusion damage and sealing failure.

[0040] When the plate A continues to slide, the second rack 27 separates from the second transmission gear 33, and then the first rack 26 and the first transmission gear 30 gradually approach and mesh, and then the first transmission gear 30 rotates in the reverse direction. Since the first transmission gear 30 and the first transmission shaft 28 are one-way rotating bearings in the prior art, the first transmission gear 30 rotates on the first transmission shaft 28, and then the first transmission shaft 28 does not rotate, so the third rack 34 and the bag fixing member 18 will not slide up and down, ensuring the stability and safety of the sealing operation of the heat sealing plate 5. With the help of the transmission unit 24, the material bag 3 is ensured to complete the bag cutting operation in the gap of the sealing operation, reducing the subsequent processing steps and improving the overall work efficiency.

[0041] In some examples, the filling and sealing equipment is refined, and a knife arm 17, a knife holder 15 and a limit member 35 are added; the knife arm 17 is slidably set on the support member 23, and the bag-fixing member 18 is set on the knife arm 17. After the knife arm 17 slides, the bag-fixing member 18 approaches or moves away from the material bag 3; the knife holder 15 is slidably set on the support member 23, and the sliding directions of the knife arm 17 and the knife holder 15 are perpendicular to each other; the cutting knife 16 is set on the knife holder 15, and after the knife holder 15 slides, the cutting knife 16 is inserted into or un-inserted into the knife groove 20; the limit member 35 is slidably set on the knife holder 15, and after the limit member 35 slides, it is used to adjust the depth of the cutting knife 16 inserted into the knife groove 20.

[0042] For example, Figure 1 to Figure 8As shown, after the transfer plate 2 moves with the material bag 3 to the sealing space 6, the two heat-sealing plates 5 approach each other until they are in squeeze contact with the material bag 3. After the material bag 3 completes the sealing operation with the help of the heat-sealing plates 5, the two heat-sealing plates 5 slide in the direction away from each other, and a sealing belt will be left on the material bag 3; the material bag 3 is located in the sealing space 6, and at this time, an external force is applied to drive the knife arm 17 to slide downward, and the knife arm 17 drives the knife holder 15, the limiter 35 and the cutting knife 16 to slide in the direction close to the sealing belt at the same time until the material bag 3 is stuck in the bag-slotting groove 19, and the cutting knife 16 is located on the side of the material bag 3; then the knife holder 15 is driven to slide on the knife arm 17 with the help of an external force. In this example, the external force used by the knife holder 15 is selected as a telescopic cylinder, an electric cylinder, etc. in the prior art. A device for linear drive can be used; when the tool holder 15 brings the cutting knife 16 close to the material bag 3 for bag cutting operation, the limiting member 35 gradually approaches the knife arm 17 with the tool holder 15 until the limiting member 35 abuts against the knife arm 17, at which time the tool holder 15 stops moving and the cutting knife 16 cuts into place, and the cutting depth of the cutting knife 16 is limited by means of the limiting member 35 to prevent the cutting distance of the cutting knife 16 from being too long, causing leakage of the material bag 3; at the same time, the limiting member 35 is installed on the tool holder 15 by means of the fastening bolts of the prior art. For different types of packaging bags, the position of the limiting member 35 on the tool holder 15 can be adjusted by tightening and loosening the fastening bolts, which is suitable for different types of material bags 3. On the basis of ensuring the consistency of the bag cutting operation, the application range of the filling and sealing equipment is expanded.

[0043] In some examples, the structure at the lowermost end of the bag slot 19 is refined, and a bag guiding arc surface 21 is added. There are two bag guiding arc surfaces 21, which are respectively located on both sides of the bag slot 19.

[0044] For example, Figure 1~Figure 2 and Figure 5~Figure 8 As shown, when the bag-fixing member 18 gradually approaches the material bag 3, the upper edge of the material bag 3 is guided into the bag-fixing groove 19 by means of the bag-guiding arc surface 21 designed at the side of the lowermost position of the bag-fixing groove 19, and the upper edge of the material bag 3 is fixed by means of the bag-fixing member 18 and the bag-fixing groove 19 to prevent the material bag 3 from being offset and deformed when the cutting knife 16 cuts the material bag 3, thereby causing the bag cutting operation to fail.

[0045] In some examples, a plurality of knife guide members 22 are added to the bag-fixing member 18 and are arranged on the bag-fixing member 18 and distributed on both sides of the knife groove 20. In this example, the number of the knife guide members 22 is four.

[0046] For example, Figure 1~Figure 2 and Figure 5~Figure 8As shown, when the knife holder 15 brings the cutting knife 16 close to the material bag 3, with the help of four knife guide members 22, it is ensured that the cutting knife 16 smoothly cuts the material bag 3 without cutting other positions; through the cooperation of the bag fixing member 18 and the knife guide member 22, the consistency of the cutting position on the material bag 3 is improved.

[0047] In some examples, the number of support members 23 and heat sealing units 4 is refined. In this example, the number of support members 23 and heat sealing units 4 are both selected to be two. Viewed along the moving direction of the material bag 3, the bag fixing member 18 is located above the sealing space 6 at the end.

[0048] For example, Figure 1~Figure 3 As shown, the filled material bag 3 is fixed on the transfer plate 2, and the transfer plate 2 rotates to transfer the material bag 3 to the sealing space 6 at the first heat sealing unit 4. The two heat sealing plates 5 in the first heat sealing unit 4 approach each other and come into contact with the outer surface of the material bag 3, and then the heat sealing plate 5 is started to heat and seal the material bag 3. After the operation of the first heat sealing unit 4 is completed, the two heat sealing plates 5 in the first heat sealing unit 4 move away from each other, the transfer plate 2 continues to rotate and continues to move the material bag 3 to the sealing space 6 at the second heat sealing unit 4, and then the two heat sealing plates 5 in the second heat sealing unit 4 approach each other and come into contact with the outer surface of the material bag 3, and the material bag 3 is sealed for the second time, ensuring that the material bag 3 is tightly sealed and leak-free, thereby improving the effectiveness and reliability of the product sealing operation. At the same time, the size of the sealing space 6 can be adjusted by the sliding heat sealing plate 5, which is suitable for material bags 3 of different thicknesses, ensuring that the material bag 3 will not be overly deformed by force extrusion when the sealing operation is completed, and will not become excessively thin, causing the risk of rupture.

[0049] In some examples, the filling and sealing equipment is refined, and a filling gun 7 is added; the filling gun 7 is slidably arranged up and down relative to the frame 1, and is located on the side of the transfer plate 2. After the filling gun 7 slides, the muzzle of the filling gun 7 extends into or cancels the extension into the material bag 3. The filling gun 7 can be selected from the equipment with filling operation in the prior art.

[0050] For example, Figure 1 and Figure 3 As shown, during operation, the material bag 3 is fixed on the transfer plate 2, and the bag mouth is opened with the help of equipment with the function of opening the bag mouth of the material bag 3 in the prior art or manually, the transfer plate 2 rotates to move the material bag 3 to the filling gun 7, the filling gun 7 slides downward, the muzzle of the filling gun 7 is inserted into the material bag 3, and the filling gun 7 is started to perform the filling operation. After the filling is completed, the filling gun 7 slides upward, and the muzzle leaves the material bag 3; then the transfer plate 2 continues to rotate, and the filled material bag 3 is transferred to the heat sealing unit 4 for sealing operation, thereby realizing the continuity of the filling and sealing operations of the material bag 3.

[0051] In some examples, the filling and sealing equipment is optimized by adding a conveyor belt 8 , which is arranged to be cyclically driven relative to the frame 1 . The conveyor belt 8 is located below the heat sealing unit 4 and is used to receive the material bags 3 after heat sealing by the heat sealing unit 4 .

[0052] For example, Figure 1 and Figure 3 As shown, after the material bag 3 is sealed, the material bag 3 falls off the transfer plate 2 and onto the conveyor belt 8. With the help of the circular transmission of the conveyor belt 8, the sealed material bag 3 is transferred to the next processing step, thereby realizing the continuous operation of sealing and unloading the material bag 3. The circular operation of the transfer plate 2 is realized.

[0053] In some examples, the filling and sealing equipment is refined, and clamping units 9 are added. There are several clamping units 9, which are arranged in sequence on the transfer plate 2 at intervals, and each clamping unit 9 is used to clamp a material bag 3; the clamping unit 9 includes two symmetrically distributed mechanical arms 10, and the mechanical arm 10 includes a clamping arm 11 and a clamping hand 14: the clamping arm 11 is swingably arranged relative to the transfer plate 2, and the clamping arm 11 has a clamping portion 12, and the clamping portion 12 has an arc surface 13, and the arc surface 13 is used to abut or cancel the abutment with the material bag 3; the clamping hand 14 is rotatably arranged relative to the clamping arm 11, and after the clamping hand 14 rotates, the clamping hand 14 clamps or cancels the material bag 3.

[0054] For example, Figure 1 to Figure 6 As shown, the material bag 3 is placed on the two clamping parts 12, the outer surface of the material bag 3 is in conflict with the arc surface 13, and then an external force is applied to drive the clamping hand 14 to rotate, and the clamping hand 14 is in extrusion contact with the material bag 3, and the material bag 3 is fixed between the clamping part 12 and the clamping hand 14. When the bag mouth of the material bag 3 needs to be opened, the two clamping arms 11 in the same clamping unit 9 rotate in a direction close to each other, so as to facilitate the opening of the bag mouth of the material bag 3. When the size of the material bag 3 changes, an external force can be applied to drive the clamping arm 11 to rotate, and the distance between the two clamping parts 12 can be appropriately adjusted to adapt to material bags 3 of different sizes; at the same time, with the help of the arc surface 13 designed on the clamping part 12, it is prevented that the surface of the material bag 3 will have obvious indentations or injuries when clamping.
