Description

Technical Field

[0001] This invention relates to the technical field of packaging, specifically to a small, rapid packaging machine. Background Technology

[0002] Bread is a common food in daily life. During production, bread is usually packaged to make it easy to carry and transport, and to reduce contact between the bread and external dust and other impurities.

[0003] The common packaging method nowadays involves manually opening the packaging bag beforehand, placing the bread inside, and then tying the bread tightly with gold thread to pack it up.

[0004] The aforementioned technical conditions also present a drawback: inconvenience in packaging.

[0005] Based on this, the present invention designs a small, rapid packaging machine to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a small, rapid packaging machine to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a small, rapid packaging machine, comprising a placement table, a vertical plate disposed on the placement table, a horizontal plate fixedly disposed on the vertical plate, a sealing device disposed on the horizontal plate, and a feeding roller disposed on the vertical plate. A feeding platform is fixedly disposed on the placement table. The sealing device includes a sealing box and a heating wire. A cylinder is fixedly disposed on the horizontal plate. A connecting plate is disposed on the sealing box. The telescopic shaft of the cylinder passes through the horizontal plate and is fixedly connected to the connecting plate. The sealing box is located above the feeding platform. The heating wire is fixedly disposed on the lower side of the sealing box. A guiding device for guiding the packaging film is disposed on the vertical plate. The guiding device includes a first rotating roller and a second rotating roller rotatably disposed on the vertical plate. The system includes a first rotating roller, a second guide roller, and a third guide roller. The first rotating roller and the second rotating roller are located above the horizontal plate, and the first guide roller is located below the second rotating roller. A placement plate is fixedly mounted on the connecting plate, and an mounting plate is vertically fixed on the placement plate. The first guide roller is rotatably mounted on the mounting plate, and the second and third guide rollers are located below the first guide roller. The feeding platform is located between the second and third guide rollers. The packaging film guided between the first and second guide rollers is the upper film, and the packaging film guided between the second and third guide rollers is the lower film. After the bread is placed between the upper and lower films, the sealing device presses down to tighten the upper and lower films. At this time, the heating wire conducts heat to seal the bread.

[0008] By adopting the above technical solution, when packaging bread, after placing the bread between the upper and lower films, the cylinder is driven to move the connecting plate downward, thereby moving the sealing box downward. The first guide roller also moves downward along with the connecting plate. As the sealing box moves downward continuously, the upper and lower films are pressed together, and the bread is wrapped between the upper and lower films. At this time, the heating wire is turned on to seal the upper and lower films, achieving the effect of convenient bread packaging.

[0009] Preferably, a telescopic spring is fixedly connected to the sealing box, and the upper end of the telescopic spring is fixedly connected to the lower surface of the connecting plate. A cutting frame is provided on the sealing box, and the cutting frame is sleeved on the outer side wall of the sealing box. Cutting teeth are provided on the lower side of the cutting frame. When the sealing box is not pressed down to tighten the upper film, the cutting frame is higher than the heating wire.

[0010] By adopting the above technical solution, after heat sealing the sealing box, the cutting frame can cut the packaging film, thereby taking out the packaged bread.

[0011] Preferably, a buffer plate is rotatably mounted on the vertical plate, and a buffer roller is rotatably mounted on the buffer plate, the buffer roller being located between the feed roller and the first rotating roller.

[0012] By adopting the above technical solution, the buffer plate can rotate when the first guide roller is pressed down, thereby buffering the packaging film and reducing damage to the packaging film.

[0013] Preferably, the horizontal plate has a stabilizing hole, and a stabilizing rod is vertically inserted into the stabilizing hole, with the lower end of the stabilizing rod fixedly connected to the connecting plate.

[0014] By adopting the above technical solution, the stabilizer bar can reduce the shaking of the connecting plate when the connecting plate moves, thereby stabilizing the connecting plate.

[0015] Preferably, an installation cylinder is vertically fixed on the connecting plate, a guide rod is inserted into the installation cylinder, the lower end of the guide rod is fixed on the sealing box, and the telescopic spring is sleeved on the guide rod.

[0016] By adopting the above technical solution, the guide rod can reduce the shaking of the sealing box when it is being sealed, thus stabilizing the sealing box.

[0017] Preferably, the feeding platform is provided with a cutting groove, and the cutting frame is inserted into the cutting groove.

[0018] By adopting the above technical solution, when the cutting frame is cutting, it can enter the cutting groove to protect the cutting teeth.

[0019] Preferably, the feeding platform is provided with a feeding trough.

[0020] By adopting the above technical solution, it is convenient to place the bread during sealing, and the upper and lower films of the film box are flush.

[0021] Preferably, a recycling roller is rotatably mounted on the vertical plate.

[0022] By adopting the above technical solution, the cut packaging film can be wound on a recycling roller to recycle the remaining packaging film, thereby reducing waste.

[0023] In summary, this application has the following beneficial technical effects: When packaging bread, after placing the bread between the upper and lower films, the cylinder is driven to move the connecting plate downward, thereby moving the sealing box downward. The first guide roller also moves downward along with the connecting plate. As the sealing box moves downward continuously, the upper and lower films are pressed together, and the bread is wrapped between the upper and lower films. At this time, the heating wire is turned on to seal the upper and lower films, achieving the effect of convenient bread packaging. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0037] like Figure 1 and Figure 2 A small, rapid packaging machine includes a placement table 1, a vertical plate 2 set on the placement table 1, a horizontal plate 3 fixedly set on the vertical plate 2, a sealing device set on the horizontal plate 3, and a feeding roller 4 set on the vertical plate 2. The packaging film is wound on the feeding roller 4, and a feeding table 25 is fixedly set on the placement table 1.

[0038] like Figure 2 and Figure 3 The vertical plate 2 is equipped with a guiding device for guiding the packaging film. The guiding device includes a first rotating roller 11, a second rotating roller 12, a second guide roller 14, and a third guide roller 15 rotatably mounted on the vertical plate 2. A buffer plate 16 is rotatably mounted on the vertical plate 2, and a buffer roller 17 is rotatably mounted on the buffer plate 16. The buffer roller 17 is located between the feed roller 4 and the first rotating roller 11. A first auxiliary roller 21 and a second auxiliary roller 22 are rotatably mounted on the vertical plate 2. The first auxiliary roller 21 is located below the first rotating roller 11, and the second auxiliary roller 22 is located below the second rotating roller 12. The first rotating roller 11 and the second rotating roller 12 are located above the horizontal plate 3.

[0039] like Figure 3 and Figure 4 The sealing device includes a sealing box 5 (combined with...) Figure 5 The sealing box 5 is a square box with an opening at the bottom. The heating wire 6 is fixedly installed at the bottom of the sealing box 5. A control switch 7 for controlling the heating wire 6 to conduct heat is installed on the vertical plate 2. The heating wire 6 is electrically connected to the control switch 7. A cylinder 8 is vertically fixed on the horizontal plate 3. A connecting plate 9 is installed on the sealing box 5. A telescopic spring 10 is fixedly installed on the upper surface of the sealing box 5 (in conjunction with...). Figure 6 The upper end of the telescopic spring 10 is fixedly connected to the connecting plate 9, the telescopic shaft of the cylinder 8 passes through the horizontal plate 3 and is fixedly connected to the connecting plate 9, and the sealing box 5 is located above the feeding platform 25.

[0040] like Figure 3 and Figure 4 A placement plate 18 is fixedly installed on the connecting plate 9, and an mounting plate 19 is vertically fixedly installed on the placement plate 18. A first guide roller 13 is rotatably installed on the mounting plate 19, and the first guide roller 13 is located below the second rotating roller 12.

[0041] like Figure 2 and Figure 3 The second guide roller 14 and the third guide roller 15 are located below the first guide roller 13. A recovery roller 23 is rotatably mounted on the vertical plate 2, located below the feed roller 4. A guide roller 24 is rotatably mounted on the vertical plate 2, located below the second guide roller 14. The feeding platform 25 is located between the second guide roller 14 and the third guide roller 15. After the packaging film comes out of the feed roller 4, it passes sequentially through the buffer roller 17, the first rotating roller 11, the first auxiliary roller 21, the second rotating roller 12, the second auxiliary roller 22, the first guide roller 13, the second guide roller 14, the third guide roller 15, the guide roller 24, and the recovery roller 23. The buffer roller 17, the first rotating roller 11, the first auxiliary roller 21, the second rotating roller 12, the second auxiliary roller 22, the first guide roller 13, the second guide roller 14, the third guide roller 15, the guide roller 24, and the recovery roller 23 guide the packaging film respectively.

[0042] like Figure 3 and Figure 4 The packaging film guided between the first guide roller 13 and the second guide roller 14 is the upper film 27, and the packaging film guided between the second guide roller 14 and the third guide roller 15 is the lower film 28. The lower film 28 is laid above the feeding platform 25. When packaging bread, the bread is placed on the lower film 28, so that the bread is between the upper film 27 and the lower film 28. At this time, neither the discharge roller nor the recovery roller 23 is rotating. The drive cylinder 8 moves the connecting plate 9 downward, thereby driving the sealing device to press down, and finally the sealing box 5 (combined with...) Figure 6When the heating wire 6 presses against the feeding platform 25, the upper film 27 and the lower film 28 are pressed together. The upper film 27 and the lower film 28 are located between the heating wire 6 and the feeding platform 25. Then, turn on the control switch 7 to allow the heating wire 6 to be energized and heated, so that the part of the upper film 27 and the lower film 28 that is in contact with the heating wire 6 is heat-sealed, thus achieving the effect of conveniently packaging bread.

[0043] like Figure 4 and Figure 5 A protective frame 29 is fixedly mounted on the sealing box 5, and a cutting frame 30 is fixedly mounted on the protective frame 29. Cutting teeth 31 are provided on the lower side of the cutting frame 30. When the sealing box 5 is not pressed down, the lower side of the cutting frame 30 is lower than the lower side of the sealing box 5.

[0044] like Figure 3 and Figure 7 The feeding table 25 is provided with a cutting groove 32 that matches the cutting teeth 31 (in combination with...). Figure 7 After the sealing box 5 presses down against the upper film 27 and the lower film 28 to seal the bread, the cylinder 8 continues to move, causing the connecting plate 9 to continue to move downward. The telescopic spring 10 is compressed by the sealing box 5 and the connecting plate 9, and the sealing box 5 stops moving downward. At the same time, the cutting frame 30 continues to move downward with the connecting plate 9 until the cutting teeth 31 enter the cutting groove 32. At this time, the packaged bread is located in the cutting frame 30. The cylinder 8 is then driven to move the telescopic shaft upward, causing the cutting frame 30 to disengage from the cutting groove 32. The heating wire 6 disengages from contact with the upper film 27 and the lower film 28, and the packaged bread is taken out, achieving the effect of easily separating the packaged bread from the packaging film.

[0045] like Figure 3 and Figure 6 When the heating wire 6 presses against the feeding table 25, the first guide roller 13 is close to the third guide roller 15, and the upper film 27 is close to the lower film 28. During sealing, the first guide roller 13 is close to the third guide roller 15, which reduces the tension of the upper film 27 and the separation between the upper film 27 and the lower film 28 after packaging. The first guide roller 13 is higher than the cutting tooth 31. When the cutting tooth 31 enters the cutting groove 32, the first guide roller 13 does not contact the third guide roller 15, thus avoiding the first guide roller 13 affecting the downward movement of the connecting plate 9.

[0046] like Figure 3 and Figure 4The buffer roller 17 contacts the upper surface of the packaging film it contacts. When the first guide roller 13 moves downward, the discharge roller and the recovery roller 23 do not rotate. The first guide roller 13 drives the buffer plate 16 to pull the packaging film downward. Under the guidance of the first rotating roller 11, the packaging film in contact with the buffer roller 17 is pulled upward. The packaging film drives the buffer plate 16 to rotate upward, thereby buffering the packaging film and preventing the packaging film from tearing due to the downward movement of the first guide roller 13 when the discharge roller stops rotating. At the same time, when the buffer plate 16 rotates, the buffer roller 17 always guides the packaging film under the action of gravity, preventing the packaging film from becoming too loose and achieving the effect of protecting the packaging film.

[0047] like Figure 2 and Figure 8 It should be noted that in this embodiment, the feed roller 4 motor is used as the power source. The motor is fixedly mounted on the vertical plate 2, and the rotating shaft of the motor 38 is coaxially fixedly mounted on the feed roller 4. At the same time, the second guide roller 14 and the recovery roller 23 both use the motor 38 as the power source.

[0048] like Figure 5 and Figure 6 A reinforcing block 37 is fixedly installed on the horizontal plate 3. A stabilizing hole 33 is vertically opened on the reinforcing block 37. A stabilizing rod 34 is vertically inserted into the stabilizing hole 33. The lower end of the stabilizing rod 34 is fixedly connected to the connecting plate 9. When the connecting plate 9 moves, the stabilizing rod 34 can reduce the shaking of the connecting plate 9 and achieve the effect of stabilizing the connecting plate 9.

[0049] like Figure 5 and Figure 6 An installation cylinder 35 is vertically fixed on the connecting plate 9. A guide rod 36 is inserted into the installation cylinder 35. The lower end of the guide rod 36 is fixed on the sealing box 5. A telescopic spring 10 is sleeved on the guide rod 36. When the sealing box 5 is sealed, the guide rod 36 can reduce the shaking of the sealing box 5 and achieve the effect of stabilizing the sealing box 5.

[0050] Reference Figure 2 and Figure 7 The feeding platform 25 has a recycling port 26. After the cutting is completed and the heating wire is no longer in contact with the packaging film, the feeding roller and recycling roller 23 continue to rotate. The packaging film passes through the recycling port 26 and contacts the guide roller 24. The recycling roller 23 recycles the cut packaging film, thereby improving the environmental protection effect.

[0051] Reference Figure 2 and Figure 7The feeding table 25 is provided with a feeding groove 20, which is an arc-shaped groove. When the panel is packaged, the feeding groove 20 is provided when the panel is placed on the lower film 28. Under the action of the weight of the bread, the lower film 28 can be allowed to collapse. When the upper film 27 is covered on the bread and then sealed, the part of the upper film 27 that contacts the bread will bulge, thereby reducing the large size difference between the upper film 27 and the lower film 28 after the bread is sealed, thus improving the appearance.

[0052] The implementation principle of this embodiment is as follows: When packaging bread, the bread is placed on the lower film 28, with the bread positioned between the upper film 27 and the lower film 28. At this time, neither the discharge roller nor the recovery roller 23 is rotating. The driving cylinder 8 moves the connecting plate 9 downward, thereby driving the sealing device to press down, ultimately causing the sealing box 5 to press against the feeding platform 25. At this time, the heating wire 6 presses the upper film 27 and the lower film 28 together, with the upper film 27 and the lower film 28 positioned between the heating wire 6 and the feeding platform 25. Then, the control switch 7 is turned on, allowing the heating wire 6 to be energized and heated, so that the parts of the upper film 27 and the lower film 28 that are in contact with the heating wire 6 are heat-sealed, achieving the effect of convenient bread packaging.

[0053] After the sealing box 5 presses down against the upper film 27 and lower film 28 to seal the bread, the cylinder 8 continues to move, causing the connecting plate 9 to continue moving downwards. The telescopic spring 10 is compressed by the sealing box 5 and the connecting plate 9, and the sealing box 5 stops moving downwards. At the same time, the cutting frame 30 continues to move downwards along with the connecting plate 9 until the cutting teeth 31 enter the cutting groove 32. At this time, the packaged bread is located in the cutting frame 30. The cylinder 8 is then driven to move the telescopic shaft upwards, causing the cutting frame 30 to disengage from the cutting groove 32. The heating wire 6 disengages from contact with the upper film 27 and lower film 28, allowing the packaged bread to be removed. This achieves the effect of easily separating the packaged bread from the packaging film.
