Description

Technical Field

[0001] The invention relates to the field of packaging machinery, in particular to an automatic water towel assembly machine. Background Art

[0002] Compressed tissue, also known as compressed cotton towel, compressed facial towel or magic tissue, is another daily necessity after paper towel and wet wipes. Compressed water towel refers to a granular product made of non-woven fabric cut into the shape of a facial towel and then compressed into a certain shape. After compression molding, the volume is generally very small. A 25x25cm facial towel can be compressed into a volume of about 2x2x1cm. Compressed water towel is a concentrated product. Under normal circumstances, it is generally not easy to open and use directly. Therefore, it needs to be opened with the help of a small amount of water dilution. After contacting water, it will immediately absorb water and expand to form a water towel.

[0003] like Figure 1-2 As shown, in the prior art, the compressed cotton towel 3333 is installed in the water towel box, and the water towel box includes a box body 1111 and a box cover 2222, the box body 1111 is provided with an annular groove 11111, and a middle hole is provided in the middle of the box body 1111, wherein the groove 11111 is used to hold water or other liquids; the box cover 2222 specifically includes an outer cover 22221 and an inner cover 22222, the box cover 2222 is buckled with one side surface of the box body 1111, and the middle hole and one end surface of the groove 11111 are closed by the box cover 2222; after turning it over, the compressed cotton towel 3333 is placed in the middle hole, and then a label 4444 is attached to the other side surface of the box body 1111, thereby closing the middle hole, and completing the product assembly. When in use, just squeeze the label to squeeze the compressed cotton towel, and transmit the pressure to the box cover through the compressed cotton towel. The inner cover of the box cover bulges outward, and a gap is formed between the box body and the box cover. Water flows out from the groove. After the compressed cotton towel contacts the water, it becomes wet and expands to form a water towel.

[0004] The difficulty in assembling the above-mentioned water towel box product lies in how to ensure the sealing during the installation process and how to improve efficiency.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] The present invention protects an automatic water towel assembly machine, which is used to assemble compressed cotton towels and a water towel box. Based on the description of the background technology of the present invention, the specific structural composition of the automatic water towel assembly machine of the present invention is introduced below.

[0039] like Figure 3-5 As shown in Figure 7, an automatic assembly machine for water towels includes a box body vibration plate 1, a box cover vibration plate 6, a cotton towel vibration plate 14, a ceramic pump filling machine 4 and a labeling machine 19. The output end of the box body vibration plate 1 is connected to a first conveying guide rail 2, and a first turntable 3 is arranged on the upper surface of the first conveying guide rail 2. The ceramic pump filling machine 4 is connected to a canning liquid outlet 5 through a conduit, and the canning liquid outlet 5 is located above the edge of the first turntable 3; it is used to inject clean water or other liquids into the groove of the box body. The ceramic pump filling machine 4 has the advantages of corrosion resistance, high temperature resistance, strong antibacterial ability and high precision. It is selected from the existing technology and its specific structure is not introduced here.

[0040] The output end of the box cover vibration plate 6 is connected to the upper cover curved rail 61, and the tail end of the upper cover curved rail 61 is provided with a flattening station 62 and a waiting station 63. A flattening cylinder 64 is arranged at the lower part of the flattening station 62; at the flattening station 62, the inner cover of the box cover that protrudes outward is flattened by pressing down the cylinder to facilitate the next process.

[0041] It also includes a vacuum suction cup 65 that can reciprocate between the first turntable 3 and the workstation to be moved 63; an outer cover pressing device 7, an inner cover pressing device 8 and a pressing and blowing device 9 are sequentially installed at the edge of the first turntable 3;

[0042] It also includes a second conveying rail 10, which is located at the edge of the first turntable 3, and a flipping device 13 is provided on the front upper surface of the second conveying rail 10, a second turntable 11 is provided on the middle upper surface of the second conveying rail 10, a cotton towel curved rail 141 is provided between the cotton towel vibration plate 14 and the second turntable 11, a cotton towel pressing cylinder 142 is installed at the end of the cotton towel curved rail 141, and a labeling machine 19 is located above the second turntable 11, and a label pressing head 191 is provided at the end of the labeling machine 19.

[0043] Specifically, a reverse cover rejection mechanism is also provided at the end of the upper cover curved rail 61, and the reverse cover rejection mechanism includes a first rejection cylinder 66 and a reverse cover bracket 67, and the reverse cover bracket 67 is installed at the end of the first rejection cylinder. A detection electric eye is provided at the edge of the to-be-moved station 63, and a height detection is performed to determine whether the cover is closed in the reverse direction. If it is reversed, the reverse cover rejection mechanism will reject the box cover with the wrong direction.

[0044] Specifically, the vacuum suction cup 65 is driven by the reciprocating mechanism 21, which includes a motor 211 and a swing rod 212. The end of the swing rod 212 is connected to a connecting rod 213, and the connecting rod 213 is connected to the vacuum suction cup 65. The connecting rod 213 is sleeved in the groove of a transverse slider 214, and a longitudinal slider 215 is connected between the connecting rod 213 and the transverse slider 214. The longitudinal slider 215 can slide longitudinally in the groove of the transverse slider 214, and the transverse slider 214 can be slidably mounted on a transverse slide rail 216. In addition, a vacuum generator is connected to one end of the vacuum suction cup 65, and air is pumped and discharged through the vacuum generator to enable the vacuum suction cup 65 to suck the box cover or detach from the box cover. The above mechanism constitutes a cover device of an automatic water towel assembly machine.

[0045] Specifically, Figure 8-9 As shown, the outer cover pressing device 7 includes a first downward pressing cylinder 71 located on the first turntable 3; the inner cover pressing device 8 includes a second downward pressing cylinder 81 located on the first turntable 3 and a lifting cylinder 82 located under the first turntable 3; the compression and blowing device 9 includes a third downward pressing cylinder 91 located on the first turntable 3 and a drying blowing joint 92 located under the first turntable 3; the lower ends of the first downward pressing cylinder 71, the second downward pressing cylinder 81 and the third downward pressing cylinder 91 are respectively connected with pressing blocks, and the upper ends of the lifting cylinder 82 are respectively connected with lifting blocks.

[0046] As for the outer cover pressing device 7, since the box cover of the water towel box includes an inner sealing cover and an outer sealing cover, the water towel box product needs to press the outer cover first and then the inner cover; the order here is more critical, otherwise after pressing the inner cover, the outer cover will be pressed, and the inner cover will be opened due to the sealed air pressure, and the seal will fail.

[0047] As for the inner cover pressing device 8, it is composed of a second downward pressing cylinder 81 and an upward pushing cylinder 82. A spring is also connected between the second downward pressing cylinder 81 and the pressing block to achieve the effect of floating compression, and to ensure the reverse force generated when pressing the inner cover, so that the box body vibrates to make the clean water overflow. The second downward pressing cylinder 81 and the upward pushing cylinder 82 have different cylinder diameters. When working at the same time, a thrust difference is formed, and the thrust of the upward pushing cylinder 82 is set to be less than the thrust of the second downward pressing cylinder 81. During specific operation, the upward pushing cylinder 82 rises first, and its top block does not contact the inner cover first, and is kept within a distance of 0.5mm. Due to the difference in force between the second downward pressing cylinder 81 and the upward pushing cylinder 82, the second downward pressing cylinder 81 slowly presses down the upward pushing cylinder 82. Since the inner cover is slowly pressed down, it can be ensured that water does not overflow.

[0048] The purpose of the compression blowing device 9 is to blow the space where the cotton towel is installed through the dry blowing joint 92 to output pressurized gas to ensure that the space where the cotton towel is installed is dry and free of water. The air is blown dry by air of a certain pressure. The third downward pressure cylinder 91 ensures that the inner cover will not open during the blowing, thereby ensuring the sealing.

[0049] Specifically, Figure 6 As shown, the flipping device 13 includes two clamping cylinders 131 and a flipping cylinder 132. The two clamping cylinders 131 are symmetrically arranged relative to the second conveying guide rail 10. A clamping block 134 is installed at the end of each clamping cylinder 131. A flipping rod 133 is connected to the end of the flipping cylinder 132. The two clamping cylinders 131 are fixedly connected to the same side of the flipping rod 133. One side surface of the clamping block 134 is arc-shaped, which matches the shape of the box body to increase the stability of clamping.

[0050] The electric eye detects that the box cover is in place, and then the two box clamping cylinders 131 clamp the box cover, and then the box cover is flipped to the rear end by the flipping cylinder 132. In this way, the box body and the box cover are flipped, so that the space for installing the cotton towel faces upward and the box cover faces downward, preparing for the subsequent placement of the cotton towel and labeling.

[0051] Specifically, Fig.10 As shown, a cotton towel blowing pipe 143 is also installed in the middle of the cotton towel curved track 141 to ensure that the cotton towel slides down smoothly; a second rejecting cylinder is also provided at the edge of the second turntable 11 to reject defective products with leaking inner covers.

[0052] Specifically, an inner cover leak detection device 20 is also provided at the edge of the second turntable 11. The inner cover leak detection device 20 is an airtightness inspection device, which is directly selected from the prior art. The present invention adopts a one-way precision leak detection system of model ZTL-0025. Since it is not an innovative point of the present invention, its structure is not specifically introduced. For the convenience of understanding, its principle is introduced here: the detection head realizes up and down movement through the cylinder. When the bottle reaches the station, the detection head is pressed down, and the sealing head presses the upper surface of the box body to form a sealed state with the box body. There is an exhaust channel in the middle of the detection head. When the sealing head is sealed in place, it is exhausted to make the cotton towel installation cavity a vacuum state. The air pressure change is detected by a precision pressure sensor. If the air pressure change is greater than a certain range, it means that the inner cover seal is leaking or the seal is not in place. For products with poor sealing, they are removed from the second turntable by the second rejection cylinder.

[0053] Specifically, a first feed cylinder 15 is provided at the entrance of the first conveying rail 2 near the first turntable 3, and a second feed cylinder 16 is provided at the entrance of the second conveying rail 10 near the second turntable 11; the first turntable 3 and the second turntable 11 are both driven by motors, and arc-shaped notches are evenly opened on the edges.

[0054] Detection electric eyes are respectively provided at a distance of about three box bodies on the left side of the first feeding cylinder 15 and the second feeding cylinder 16. The detection electric eyes are respectively located on the first conveying rail 2 or the second conveying rail 10 for detecting whether there is a box body.

[0055] Specifically, the label pressing head 191 is provided with a plurality of exhaust holes, which are connected to the vacuum generator; the label pressing head 191 is driven by the labeling cylinder. After the label is discharged through the conveying mechanism, the label pressing head 191 can use vacuum suction to suck the label, and then press the label onto the bottle body through the labeling cylinder. It should be noted that the transmission component of the labeling machine 19 adopts the commonly used technical means in this field, which is not the innovation point of the present invention, so the specific structure of the labeling machine 19 is not described here.

[0056] Specifically, a beam sensor 18 and a third reject cylinder 17 are also provided on the second conveying rail 10, and the beam sensor 18 is located on the left side of the third reject cylinder 17. The tail end of the second conveying rail 10 is also connected to a turning rail.

[0057] It should be noted that the detection electric eye is a common technical means in this field and is a standard part. It generally uses a photosensitive element as a sensing element to work, and senses different light reflections, and has different reactions in the measurement circuit. The present invention directly selects the electric eye from the prior art, so there is no need to explain its specific structure.

[0058] The present invention also has detection electric eyes at other places to determine the location of objects, etc. The specific installation locations will not be described in detail.

[0059] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
