Description

Technical Field

[0001] The utility model relates to the technical field of towel packaging, in particular to a towel folding and packaging machine. Background Art

[0002] In the packaging industry, there is a need to fold towels before packaging. Since the towels obtained after cutting in the processing and production link are in an unfolded state, but before the towels are sold to consumers at the terminal, they must go through various packagings. Especially for towels supplied to restaurants and hotels, the towels need to be folded and put into a packaging bag first, and then the packaging bag is sealed before supply. However, in the current industry, manual folding and bagging of towels are first carried out, and then the bags are manually sealed. This packaging method has the disadvantages of low packaging efficiency and great waste of labor.

[0003] Therefore, there is an urgent need to provide a towel folding and packaging machine with high packaging efficiency and labor saving. Content of the Utility Model

[0004] Aiming at the above-mentioned deficiencies of the prior art, to achieve an object of the present utility model, a towel folding and packaging machine is provided, including: a feeding component for conveying the towel to be folded to the folding position; a folding component for folding the towel to be folded at the folding position to obtain a folded towel; a bag storage tank for storing packaging bags; a bag opening component for opening the packaging bag to obtain an opened packaging bag so that the opened packaging bag receives the folded towel; a bag taking component for taking out the packaging bag from the bag storage tank and transferring it to the bag opening component; and a sealing component for sealing the opened packaging bag that has received the folded towel.

The sealing assembly 6 is used to seal the opened packaging bag 200 that has received the folded towel. Therefore, the towel folding and packaging machine provided by the present utility model can automatically fold the towel by setting the folding assembly 2, and can automatically package the folded towel by setting the bag opening assembly 3, the bag taking assembly 5 and the sealing assembly 6, and thus has the advantages of high packaging efficiency and labor saving.

[0026] Please refer to Figures 1 to 3 Specifically, the towel folding and packaging machine further includes a feeding platform 11 on which a plurality of towels 100 to be folded are placed. The feeding assembly includes a feeding belt 1. The folding assembly 2 includes a first folding knife 21, a first folding forming groove 22 docked with the first folding knife 21, a second folding knife 23, a second folding forming groove 24 docked with the second folding knife 23, and a third folding knife 25. The bag opening assembly 3 is docked with the third folding knife 25. The first folding knife 21 and the third folding knife 25 reciprocate in the vertical direction, and the second folding knife 23 reciprocates in the horizontal direction. The second folding knife 23 is horizontally arranged and perpendicular to the vertically arranged first folding knife 21. The first folding forming groove 22 includes a pair of opposite first folding forming groove plates (not shown), and a first gap for accommodating the first folding knife 21 and the towel folded by the first folding knife 21 is provided between the pair of first folding forming groove plates. The second folding forming groove 24 includes a pair of opposite second folding forming groove plates (not shown), and a second gap for accommodating the second folding knife 23 and the towel folded again by the second folding knife 23 is provided between the pair of second folding forming groove plates. The pair of first folding forming groove plates are arranged horizontally and opposite to each other in the front and back, and preferably a first folding forming groove opening is provided at the middle position. The first folding forming groove opening corresponds to the second gap. The pair of second folding forming groove plates are arranged vertically and opposite to each other up and down, and preferably a second folding forming groove opening is provided at the middle position.

[0027] When the towel 100 to be folded is conveyed below the first folding knife 21, the first folding knife 21 moves downward in the vertical direction to fold the towel 100 to be folded in half from its middle position into the first folding forming groove 22 docked with it. After the first folding knife 21 folds the towel 100 to be folded in half, it returns to its original position. The second folding knife 23 rotates in the horizontal direction to fold the towel 100 to be folded that has been folded once in half again into the second folding forming groove 24 docked with it. The second folding knife 23 enters the second gap through the first folding forming groove opening. After the second folding knife 23 completes folding the towel 100 to be folded in half again, it returns to its original position. The third folding knife 25 folds the towel 100 to be folded for the third time through the second folding forming groove opening to obtain a folded towel and sends it into the opened packaging bag opened by the bag opening assembly 3. In this way, the folding assembly 2 folds the towel three times, making the towel neatly folded, thereby reducing the space occupied in the length direction and facilitating packaging.

[0028] Please refer to Figure 1 、 Figure 3 and Figure 4, preferably, the towel folding and packaging machine further includes a bag pulling assembly 7 disposed below the sealing assembly 6. The bag pulling assembly 7 includes a first opening cylinder 31, a first bag pulling finger 32, a second bag pulling finger 33, a second opening cylinder 34, a third bag pulling finger 35, a fourth bag pulling finger 36, a first clamping cylinder 37, and a second clamping cylinder 38. Both the first bag pulling finger 32 and the second bag pulling finger 33 are drivingly connected to the first opening cylinder 31 and approach or move away from each other under the drive of the first opening cylinder 31. Both the third bag pulling finger 35 and the fourth bag pulling finger 36 are drivingly connected to the second opening cylinder 34 and approach or move away from each other under the drive of the second opening cylinder 34. The first bag pulling finger 32 and the third bag pulling finger 35 are opposite to each other and move relatively synchronously. The second bag pulling finger 33 and the fourth bag pulling finger 36 are opposite to each other and move relatively synchronously. The first clamping cylinder 37 is used to drive the first bag pulling finger 32 and the second bag pulling finger 33 to move. The second clamping cylinder 38 is used to drive the third bag pulling finger 35 and the fourth bag pulling finger 36 to move. Under the combined drive of the first clamping cylinder 37 and the second clamping cylinder 38, the first bag pulling finger 32 and the third bag pulling finger 35 approach or move away from each other, and correspondingly, the second bag pulling finger 33 and the fourth bag pulling finger 36 approach or move away from each other. In this way, since the towel is relatively thick after being folded and the packaging bag is even more bulging after the towel is put into the packaging bag, by providing the bag pulling assembly 7 below the sealing assembly 6, the opening of the packaging bag containing the towel can be flattened, ensuring that the sealing of the opening is flat and beautiful.

[0029] Please refer to Figure 4, Further preferably, the bag pulling assembly 7 further includes a first moving plate 39 and a second moving plate 310 opposite to each other, a first mounting plate 311, a second mounting plate 312, a support plate 313, a third moving plate 314 and a pair of guide rods 315. The first mounting plate 311 is fixed to the first moving plate 39, and the first opening cylinder 31 is mounted on the first mounting plate 311. The second mounting plate 312 is fixed to the second moving plate 310, and the second opening cylinder 34 is mounted on the second mounting plate 312. The support plate 313 is opposite to the second mounting plate 312. The support plate 313 and the first moving plate 39 are located on both sides of the second moving plate 310. The second clamping cylinder 38 is disposed on the support plate 313 and is drivingly connected to the second moving plate 310. The third moving plate 314 is opposite to the support plate 313. The third moving plate 314 and the second moving plate 310 are located on both sides of the support plate 313. The first clamping cylinder 37 is disposed on the support plate 313 and faces away from the second clamping cylinder 38. The first clamping cylinder 37 is drivingly connected to the third moving plate 314. Both ends of a pair of guide rods 315 are fixed to the first moving plate 39 and the third moving plate 314 respectively and pass through the support plate 313 and the second moving plate 310. Driven by the first clamping cylinder 37 and the second clamping cylinder 38 together and guided by the guide rods 315, the first moving plate 39 and the second moving plate 310 approach or move away from each other. Therefore, the two pairs of bag pulling fingers can stably and reliably clamp and flatten the bag mouth of the packaging bag under the drive of each clamping cylinder and each opening cylinder.

[0030] Further preferably, an anti-slip rubber sleeve (not shown) is sleeved on each bag pulling finger. In this way, by sleeving the anti-slip rubber sleeve, not only can each bag pulling finger apply enough pulling force to open the bag mouth of the packaging bag, but also it is ensured that the packaging bag is not scratched.

[0031] Please refer to Figures 1 to 3 and Figure 5 , Preferably, the towel folding and packaging machine further includes a lifting and exhausting assembly 8. The lifting and exhausting assembly 8 is used to exhaust the opened packaging bag 200 containing the folded towel and transport it to the sealing assembly 6. The lifting and exhausting assembly 8 includes two opposite exhausting clamping plates 81, a first moving plate 82, a second moving plate 83, a pair of first guide rods 84, a first exhausting cylinder 85 and a second exhausting cylinder 86. The first moving plate 82 and the second moving plate 83 are respectively fixed to an exhausting clamping plate 81, especially at its end. A pair of first guide rods 84 are disposed between the first moving plate 82 and the second moving plate 83. The first exhausting cylinder 85 and the second exhausting cylinder 86 are respectively drivingly connected to the first moving plate 82 and the second moving plate 83 and drive the first moving plate 82 and the second moving plate 83 to make relative movements of approaching or moving away from each other. Since the folded towel is put into the packaging bag and makes the bag of the packaging bag relatively bulging, by providing the lifting and exhausting assembly 8, the packaging bag can be exhausted and compressed, thereby ensuring reliable sealing and the aesthetic appearance of the seal.

[0032] Please refer to Figure 5 , further preferably, the lifting and exhaust assembly 8 further includes: a pair of oppositely arranged support plates 87, a third moving plate 88, a pair of second guide rods 89, and a lifting drive 810. The third moving plate 88 is movably arranged between the pair of support plates 87. The pair of second guide rods 89 are correspondingly supported by the pair of support plates 87. The lifting drive 810 is arranged on one support plate 87 and is drivingly connected to the third moving plate 88. The lifting drive 810 drives the third moving plate 88 to reciprocate vertically under the guidance of the second guide rods 89. In this way, the lifting and exhaust assembly 8 can not only exhaust the packaging bag, but also use the lifting drive 810 to drive a pair of exhaust clamping plates 81 to timely clamp the opened packaging bag 200 filled with the folded towel and move it to the sealing position until it is released and then fall onto the output belt 9.

[0033] Please refer to Figure 5 , further preferably, in the case where the first bag pulling finger 32 and the second bag pulling finger 33 are in the initial state of approaching each other and the third bag pulling finger 35 and the fourth bag pulling finger 36 are also in the initial state of approaching each other, there is a gap between the respective bag pulling fingers. When the opened packaging bag has received the folded towel, a pair of exhaust clamping plates 81 move away from each other under the drive of the exhaust cylinder, and rise through the gap under the drive of the lifting drive 810. The exhaust cylinder then drives the pair of exhaust clamping plates 81 to approach each other to clamp and exhaust the opened packaging bag. The lifting drive 810 drives the pair of exhaust clamping plates 81 to hold the exhausted opened packaging bag and descend to the sealing position for receiving the sealing by the sealing assembly 6. At the sealing position, the packaging bag is located between the two opposite sealing knives of the sealing assembly 6. At the same time, the packaging bag is located between the first bag pulling finger 32 and the third bag pulling finger 35 and between the second bag pulling finger 33 and the fourth bag pulling finger 36. Under the common drive of the first clamping cylinder 37 and the second clamping cylinder 38, the first bag pulling finger 32 and the third bag pulling finger 35 approach each other to clamp the opposite sides of one half of the bag mouth of the packaging bag, and the second bag pulling finger 33 and the fourth bag pulling finger 36 approach each other to clamp the opposite sides of the other half of the bag mouth of the packaging bag. Under the common drive of the first opening cylinder 31 and the second opening cylinder 34, the first bag pulling finger 32 and the second bag pulling finger 33 move away from each other and the third bag pulling finger 35 and the fourth bag pulling finger 36 synchronously move away from each other, so that the bag mouth of the packaging bag is flattened. As described above, the automation degree of the entire exhaust process and the bag mouth flattening process is high, and the working effect is good.

[0034] Please refer to Figure 1, preferably, the towel folding and packaging machine further includes an output belt 9 located below a pair of exhaust clamping plates 81. The exhaust cylinder drives the pair of exhaust clamping plates 81 to move away from each other so that the packaging bag sealed by the sealing assembly 6 falls onto the output belt 9. Therefore, the sealed packaging bag can stably fall onto the output belt 9, without falling from a high position and popping out of the towel folding and packaging machine, and the output belt 9 can timely output the packaging bag to the outside.

[0035] Please refer to Figure 5 , specifically, a bag dropping detection sensor 10 is provided below one of the exhaust clamping plates 81. The bag dropping detection sensor 10 detects whether the sealed packaging bag normally drops onto the output belt 9, and generates a detection signal for alarm and shutdown when it detects that the bag does not drop normally. In this way, it prevents the packaging bag from staying at the sealing position and other unexpected situations from causing faults in the whole machine, and avoids damage to the whole machine.

[0036] Finally, it should be understood that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
