[0029] In some embodiments, please refer to Figures 1 to 3 The present application provides a paper towel packaging machine 100, which includes: a film supply device 10, a film pulling mechanism 20, a pushing mechanism 40 and a pressing mechanism 50. The film supply device 10 is used to provide a packaging film 200, and a film pulling channel 21 extending along a first direction X is formed between the film pulling mechanism 20 and the film supply device 10, and the film pulling mechanism 20 is used to pull the packaging film 200 in the film supply device 10 into the film pulling channel 21. The pushing mechanism 40 has a pushing station 41 located on one side of the film pulling channel 21 along a second direction Y, and the pushing mechanism 40 is used to push the product 300 located on the pushing station 41 to the surface of the packaging film 200 along the second direction Y, and break the packaging film 200 by pushing the product 300, wherein the first direction X intersects with the second direction Y. The pressing mechanism 50 is used to press the two folded edges 210 of the broken packaging film 200 onto a surface of the product 300.

[0030] In the above-mentioned paper towel packaging machine 100, during the packaging process, the packaging film 200 is provided by the film supply device 10; the packaging film 200 is then pulled out from the film supply device 10 by the film pulling mechanism 20, and the packaging film 200 is stretched into the film pulling channel 21, at which time the packaging film 200 is located on one side of the pushing station 41 along the second direction Y; then, the product 300 located at the pushing station 41 is pushed toward the packaging film 200 by the pushing mechanism 40, and the product 300 is pressed against the packaging film 200 by the thrust force and the packaging film 200 is pulled apart. Since the packaging film 200 is pulled apart by the squeezing of the product 300, the pulled apart packaging film 200 is easily wrapped around the surface of the product 300; finally, the two folded edges 210 of the packaging film 200 are respectively pressed on the same surface of the product 300 by the pressing mechanism 50 to complete the wrapping of the product 300. In this way, compared with the traditional wrapping method, the paper towel packaging machine 100 uses a pushing and pressing method to directly squeeze the shorter product 300 and wrap it in the packaging film 200, overcoming the problem that the traditional packaging machine is inconvenient to wrap due to its short size, and achieving effective wrapping, thereby meeting the packaging needs of shorter paper towels and reducing production costs.

[0031] It should be noted that the paper towel packaging machine 100 of this embodiment is not only suitable for packaging shorter paper towels, but also suitable for packaging larger paper towels, for example: the length of the paper towel is not less than 800 mm.

[0032] During the packaging process, the film-drawing mechanism 20 stretches the packaging film 200 into the film-drawing channel 21, so that the packaging film 200 is in a tensioned state and is located on one side of the pushing station 41 along the second direction Y, so that the product 300 can contact the surface of the packaging film 200 under the pushing of the pushing mechanism 40, and as the pushing continues, the packaging film 200 can be broken and wrapped on the surface of the product 300. Among them, the wrapping of this embodiment refers to wrapping part of the surface of the product 300. For ease of understanding, taking the rectangular hand towel as an example, when wrapping, the four surfaces of the hand towel are wrapped by the packaging film 200. Among them, in some specific examples, the first direction X and the second direction Y are perpendicular to each other. At the same time, the first direction X, the second direction Y and the height direction Z of the hand towel packaging machine 100 are perpendicular to each other, and the three are not coplanar.

[0033] In order to ensure that the packaging film 200 is pulled apart, during the production process, a softer film material may be selected, such as PET (polyethylene glycol terephthalate), PVC (Polyvinylchloride), etc. At the same time, an easy-tear line may be pre-set on the packaging film 200; of course, a cutting device may also be provided, and when the packaging film 200 is squeezed, the packaging film 200 may be cut synchronously by the cutting device, so that the packaging film 200 is easily pulled apart.

[0034] In addition, when the packaging film 200 is pulled apart, two unclosed folded edges 210 will appear. For this reason, the present embodiment introduces a pressing mechanism 50 to press the two folded edges 210. During pressing, an adhesive is provided on the packaging film 200 or the product 300 in advance, such as pre-applying glue, etc. In some specific examples, during the packaging process, glue can be applied on the packaging film 200 by a glue coating device, so that one folded edge 210 on the broken packaging film 200 has glue, so that during pressing, the other folded edge 210 is bonded to the folded edge 210 with glue, so that the packaging film 200 forms a closed loop and wraps the product 300. Since the glue coating device is not the object to be improved in the present embodiment, its specific structure is not described in detail here, and the existing literature can be directly referred to.

[0035] Of course, before wrapping, a corresponding tape may also be provided on the outer surface of the product 300 so that both folded edges 210 can be pressed onto the paper towel, and no specific limitation is made to this.

[0036] For further information, please refer to Figure 2 The pushing mechanism 40 includes a first driver 42 and a pushing member 43. The first driver 42 is located at a side of the pushing station 41 away from the film-drawing channel 21, and is used to drive the pushing member 43 to reciprocate along the second direction Y. It can be seen that when the packaging film 200 is stretched into the film-drawing channel 21, the first driver 42 drives the product 300 to move from the pushing station 41 toward the film-drawing channel 21, so that the product 300 contacts the packaging film 200, and the packaging film 200 is broken to be wrapped around the product 300.

[0037] The first driver 42 may be, but is not limited to, a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, etc.; of course, it may also be a combination of a motor and a transmission mechanism, such as a combination of a motor and a screw drive, etc.

[0038] At the same time, in order to facilitate pushing the product 300, the pushing member 43 can be designed as a plate-like structure to increase the contact area with the product 300 and improve the stability of pushing.

[0039] In some embodiments, please refer to Figure 2The film-drawing mechanism 20 includes a guide rail 22 and a film-drawing member 23. The guide rail 22 extends along the first direction X. The film-drawing member 23 is slidably arranged on the guide rail 22, and one end of the film-drawing member 23 is located in the film-drawing channel 21. The film-drawing member 23 is configured to slide along the first direction X to the film-feeding device 10 and fix the packaging film 200 of the film-feeding device 10. It can be known that when the product 300 is located at the pushing station 41, the film-drawing member 23 can be driven to slide on the guide rail 22 to reach the film-feeding device 10 along the first direction X; after reaching, one end of the packaging film 200 is fixed by the film-drawing member 23; then, the film-drawing member 23 is driven to move back along the first direction X, and the packaging film 200 is pulled out of the film-drawing mechanism 20 and extended on one side of the pushing station 41. Such a design facilitates the stretching of the packaging film 200 and facilitates stable packaging.

[0040] It should be noted that there are many ways for the film-drawing member 23 to fix the packaging film 200, such as vacuum adsorption, clamping, etc. At the same time, in order to improve the stability of the film-drawing member 23 in stretching the packaging film 200, the number of the film-drawing members 23 can be more than two, and all the film-drawing members 23 are distributed at intervals along the height direction Z of the paper towel packaging machine 100, so that one end of the packaging film 200 can be fixed by multiple film-drawing members 23 at the same time, so that the force is balanced during the stretching process, and the stability of the film drawing is improved.

[0041] In addition, the film pulling member 23 can slide on the guide rail 22 by manual drive or automatic drive, for example, by driving the film pulling member 23 to slide on the guide rail 22 by a cylinder, a hydraulic cylinder, an electric cylinder or other equipment.

[0042] For further information, please refer to Figure 2 and Figure 4 The film-drawing member 23 has an adsorption channel 231, and the side of the film-drawing member 23 is provided with an adsorption hole connected to the adsorption channel 231. One end of the adsorption channel 231 is used to communicate with the suction device, and the adsorption hole is used to adsorb the packaging film 200. It can be seen that when the packaging film 200 is fixed, the adsorption channel 231 can be sucked by the suction device to form a negative pressure in the adsorption hole. At this time, the adsorption hole of the film-drawing member 23 acts on the packaging film 200, so that the packaging film 200 is stably adsorbed on the film-drawing member 23.

[0043] It should be noted that, in order to ensure the negative pressure in the adsorption hole, the adsorption channel 231 can be designed to be open at one end and closed at the other end. The open end is connected to the suction device. At the same time, the number of adsorption holes can be one or more. In addition, in order to facilitate the adsorption of the packaging film 200, the film drawing member 23 can be designed as a tubular structure with adsorption holes on its side.

[0044] In some embodiments, please refer to Figure 2The paper towel packaging machine 100 further includes a transfer platform 30, which is located between the film-drawing channel 21 and the pushing station 41, and has a transfer channel 33 on the transfer platform 30, which is connected between the pushing station 41 and the film-drawing channel 21. In this way, the transfer platform 30 is introduced to provide a stable transfer channel 33 for pushing the product 300 from the pushing station 41 to the film-drawing channel 21, thereby achieving stable and effective transfer.

[0045] For further information, please refer to Figure 2 and Figure 5 The transfer platform 30 includes a base 31 and protective members 32 respectively disposed on both sides of the base 31 along the first direction X. The two protective members 32 and the base 31 are enclosed to form a transfer channel 33. In this way, the protective members 32 on both sides can form left and right limits for the product 300, thereby preventing the product 300 from deviating during the pushing process and causing packaging failure, thereby improving the packaging yield.

[0046] It should be noted that the two protective members 32 can be installed on the base 31 in a fixed manner or in an adjustable manner. For example, a slide groove extending along the first direction X can be provided on the base 31, and the protective member 32 is at least partially inserted into the slide groove, and moves back and forth along the first direction X on the base 31 under the drive of a driving device such as a cylinder, a hydraulic cylinder, or an electric cylinder, etc. In this way, by changing the spacing between the protective members 32, it can be suitable for limiting the position of products 300 of different sizes.

[0047] In some embodiments, please refer to Figure 2 and Figure 5 The side of the protective member 32 facing the film-drawing passage 21 is provided with a guide hole 321, and the guide hole 321 is used for at least part of the film-drawing mechanism 20 to be inserted. It can be seen that during the film-drawing process, the film-drawing mechanism 20 can be guided by the guide hole 321, so that the movement of the film-drawing mechanism 20 is more stable, ensuring stable film-drawing.

[0048] When the film-pulling mechanism 20 includes the guide rail 22 and the film-pulling member 23 , the side surface of the film-pulling member 23 can be inserted into the guide hole 321 , so that the film-pulling member 23 can reciprocate along the first direction X in the guide hole 321 .

[0049] In some embodiments, please refer to Figure 2 and Figure 5 The paper towel packaging machine 100 further includes a discharge platform 60 located on the side of the film pulling channel 21 facing away from the pushing station 41, and the pressing mechanism 50 includes two pressing components 5a. The pushing mechanism 40 is used to push the product 300 from the pushing station 41 to the discharge platform 60 to break the packaging film 200, and the two pressing components 5a are respectively located on opposite sides of the discharge platform 60 along the first direction X, and respectively correspond to the folded edges 210 used for pressing the packaging film 200.

[0050] It can be seen that after the pushing mechanism 40 pushes the product 300 to contact the packaging film 200, it continues to push the product 300 to pass through the film pulling channel 21 and enter the discharge platform 60. At this time, the packaging film 200 is broken due to excessive pulling force. Then, the pressing components 5a located on both sides of the discharge platform 60 press the two folded edges 210 of the packaging film 200 onto the product 300 in sequence to complete the packaging operation.

[0051] It should be noted that the discharge platform 60 is located on one side of the film pulling channel 21. When the product 300 is pushed from the pushing station 41 to the discharge platform 60, it means that the packaging film 200 can be stretched for a certain distance, ensuring that the pushing mechanism 40 can break the packaging film 200. When the pressing assembly 5a completes the pressing of the folding edge 210, the wrapped product 300 can be pushed out of the discharge platform 60 through the pushing mechanism 40.

[0052] In addition, to facilitate the pressing of the folded edge 210 , the two pressing components 5 a are both located at one end of the discharge platform 60 close to the film drawing channel 21 , and are located on both sides of the discharge platform 60 along the first direction X.

[0053] For further information, please refer to Figure 2 and Figure 6 Each pressing assembly 5a includes a second driver 51 and a pressing member 52. The second driver 51 is used to drive the pressing member 52 to move back and forth along the first direction X to press the folded edge 210 of the packaging film 200 onto the surface of the product 300. In this way, after the packaging film 200 is pulled apart to form two folded edges 210, the second driver 51 drives the pressing member 52 to move along the first direction X to ensure that the folded edge 210 is bent onto the surface of the product 300.

[0054] In order to prevent the pressing piece 52 from scratching the packaging film 200 during the film pulling process, a guide surface 521 can be set on the side of the pressing piece 52 facing the film pulling channel 21. The guide surface 521 is constructed to be inclined on the pressing piece 52 or to be raised along a circular arc on the side facing the film pulling channel 21. This can reduce the chance of the pressing piece 52 scratching the packaging film 200 and improve the stability of the packaging operation.

[0055] At the same time, in order to facilitate the second driver 51 to drive the pressing member 52 to move, the pressing assembly 5a also includes a connecting member 53, which at least partially extends along the first direction X and is connected between the second driver 51 and the pressing member 52.

[0056] The second driver 51 refers to a device that provides power for the movement of the pressing part 52, which may be, but is not limited to, a cylinder, a hydraulic cylinder, an electric cylinder, etc., and may also be a combination of a motor and a screw mechanism, a gear rack, etc.

[0057] In some embodiments, please refer to Figure 2The paper towel packaging machine 100 further includes a feeding mechanism 70, which is located at least on one side of the pushing station 41 along the first direction X, and is used to convey the product 300 to the pushing station 41. In this way, the feeding mechanism 70 automatically provides the packaging film 200 during the packaging process, ensuring that the packaging operation is carried out continuously and stably.

[0058] It should be noted that the number of the feeding mechanisms 70 can be one or two. When there are two feeding mechanisms 70, the two feeding mechanisms 70 can be respectively located on opposite sides of the pushing station 41 along the first direction X, so that in the first direction X, the two feeding mechanisms 70 can push the product 300 left and right, and can ensure that the product 300 accurately arrives at the pushing station 41.

[0059] Among them, please refer to Figure 2 The feeding mechanism 70 includes a third driver 71 and a feeding member 72 driven by the third driver 71. The third driver 71 is used to drive the feeding member 72 to reciprocate along the first direction X, so that the product 300 arrives at the pushing station 41 along the first direction X. The third driver 71 can be, but is not limited to, a cylinder, a hydraulic cylinder, an electric cylinder, etc.

[0060] In some embodiments, please refer to Figure 1 The film supply device 10 includes a film placing mechanism 11 and a film cutting mechanism 12. The film placing mechanism 11 is used to release the packaging film 200 to the film cutting mechanism 12. A film pulling channel 21 is formed between the film cutting mechanism 12 and the film pulling mechanism 20. The film cutting mechanism 12 is used to cut the packaging film 200. It can be seen that in the process of providing the packaging film 200, the packaging film 200 can be cut by the film cutting mechanism 12 to ensure that the packaging film 200 is effectively pulled off.

[0061] It should be noted that the film placing mechanism 11 refers to a film placing roller that can rotate around its own axis, and during operation, the roll of packaging film 200 can be sleeved on the film placing roller. Meanwhile, the film cutting mechanism 12 refers to a mechanism including a cutter, and can also include structures such as a tensioning roller. Since the structures of the film placing mechanism 11 and the film cutting mechanism 12 themselves are not the objects to be improved in this embodiment, they are not described in detail here, and the existing literature or existing product 300 can be directly referred to.

[0062] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
