Description

Technical Field

[0001] The utility model relates to the technical field of disposable sanitary products, in particular to a heat-pressing cutting device for menstrual pants. Background Art

[0002] The composite core of menstrual pants is usually composed of non-woven fabrics, polymer water-absorbent resins, breathable membranes and other materials, which together constitute the core part of menstrual pants.

[0003] Our company has applied for a Chinese utility model patent with the authorization number "CN 219383049 U". It is a sealing and cutting integrated knife holder, including a frame, an upper roller and a lower roller. Since the blade of this device is set between the hot pressing roller part, the hot pressing roller part simultaneously performs hot pressing and sealing on the cut part of the product. Compared with the traditional cutting and heat sealing process, it is necessary to first perform hot pressing and sealing on both ends of the cut position of the product, and then cut the heat sealed position. There is no need for two sealing and cutting devices, which shortens the whole machine and solves the problem that the existing whole machine is much longer in length after packaging, sealing and cutting, which is difficult to meet the technical requirements for small customer factories.

[0004] In practical applications, the above device still has defects;

[0005] 1. It is difficult for the cutter to cut the cut part after heat pressing and sealing, and it needs to be cut again manually or by machine, which reduces production efficiency;

[0006] 2. Since the trousers on the lower roller go through the hot press sealing-cutting-hot press sealing process in sequence, the trousers are subjected to tension during the first hot press sealing process, causing the trousers to stretch. After cutting, the position of the blade is far away from the second hot press sealing position, so that the incision is not in the middle of the two hot press seals, resulting in asymmetry on both sides of the trousers, affecting the quality of the trousers. Utility Model Content

[0007] The purpose of the present utility model is to provide a heat-pressing cutting device for menstrual pants to solve the problems raised in the above-mentioned background technology.

[0008] To achieve the above-mentioned object, the present invention provides the following technical solution: a heat-pressing and cutting device for menstrual pants, comprising a mounting plate, a pressure roller and an anvil roller being movably provided on the side of the mounting plate, the pressure roller being located directly above the anvil roller, and the menstrual pants being located between the pressure roller and the anvil roller;

[0009] The surface of the anvil roller is provided with a plurality of first adsorption holes, through which the menstrual pants are adsorbed, and the surface of the anvil roller is also provided with at least one sedimentation tank;

[0010] The pressing roller comprises a roller body and at least one hot-pressing and cutting assembly arranged on the roller body, and the menstrual pants are cut by the hot-pressing and cutting assembly.

[0011] Preferably, the hot pressing cutting assembly includes two hot pressing protrusions, a mounting groove is formed between the two hot pressing protrusions, and a cutting blade is installed in the mounting groove;

[0012] The top end surface of the cutting knife extends out of the mounting groove and is matched with the settling trough.

[0013] Preferably, a tensioning roller is provided on the feed side of the anvil roller, and the tensioning roller generates tensioning force on the menstrual pants to ensure that the menstrual pants are adsorbed on the upper surface of the anvil roller.

[0014] Preferably, the discharge side of the anvil roller is provided with a material transfer assembly and a conveying assembly;

[0015] The material transfer assembly includes a rotating shaft and a T-shaped suction plate, and the T-shaped suction plate is provided with a plurality of second adsorption holes;

[0016] The end surface of the rotating shaft is provided with a plurality of through holes connected to the second adsorption holes;

[0017] The conveying component conveys the cut menstrual pants.

[0018] Preferably, a barrier is provided at the bottom of the anvil roller, the barrier comprises a rotating rod and a surrounding plate, and the distance between the surrounding plate and the anvil roller is 0.5-1 mm.

[0019] Preferably, slopes are formed on both sides of the enclosure.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] The hot-pressing cutting device for menstrual pants has a top surface of a cutting knife extending out of a mounting groove and adapted to a sedimentation tank. During cutting, the cutting knife is inserted into the sedimentation tank, thereby completely cutting adjacent menstrual pants without the need for secondary processing, thereby improving production efficiency.

[0022] At the same time, the trouser body is tensioned by the tensioning roller, and the top of the trouser body is adsorbed by the anvil roller. At this time, the position of the trouser body remains unchanged, ensuring the stability of the trouser body and preventing the trouser body from generating tension during the first hot pressing and sealing process. The incision is located in the middle of the two hot pressing seals, making the two sides of the menstrual pants symmetrical after cutting, thereby improving the quality of the menstrual pants.

[0023] Furthermore, a material transfer assembly and a conveying assembly are also provided. When the menstrual pants move to the side of the anvil roller, the side of the T-shaped suction plate contacts the menstrual pants, and the menstrual pants are adsorbed by the T-shaped suction plate, thereby removing the menstrual pants from the anvil roller. When the T-shaped suction plate rotates to the top of the conveying assembly, the controller controls the fan to stop or reverse the fan. At this time, the menstrual pants fall onto the conveyor belt of the conveying assembly for transportation and enter the next process, further improving production efficiency.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] This device is specially used for cutting off menstrual pants.

[0030] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: a heat-pressing cutting device for menstrual pants, comprising a mounting plate 1, a pressure roller 2 and an anvil roller 4 movably provided on the side of the mounting plate 1, the pressure roller 2 being located directly above the anvil roller 4, the menstrual pants 9 being located between the pressure roller 2 and the anvil roller 4, and one side of the menstrual pants 9 being wound on a reel or other similar reeling device;

[0031] A plurality of first adsorption holes are provided on the surface of the anvil roller 4. It can be seen that the menstrual pants 9 are adsorbed through the first adsorption holes. At least one sedimentation tank 401 is also provided on the surface of the anvil roller 4.

[0032] The pressing roller 2 includes a roller body and at least one hot-pressing and cutting assembly 3 provided on the roller body, and the menstrual pants 9 are cut by the hot-pressing and cutting assembly 3 .

[0033] In a specific embodiment of the present solution, the number of the sedimentation tank 401 is set to one, and the number of the hot pressing cutting components 3 is set to two, so that the pressure roller 2 can cut two menstrual pants after rotating one circle.

[0034] like Figure 2As shown, the hot pressing and cutting assembly 3 includes two hot pressing protrusions 301, and an installation groove is formed between the two hot pressing protrusions 301. A cutting knife 302 is installed in the installation groove. The cutting knife 302 seals and cuts the two ends of the continuous product passing through. Since the cutting knife 302 is arranged between the hot pressing protrusions 301, the hot pressing protrusion 301 simultaneously performs hot pressing and sealing on the cutting part of the product passing through. Compared with the traditional cutting and heat sealing process, it is necessary to first perform hot pressing and sealing on the two ends of the cutting position of the product and then cut the heat sealing position. There is no need for two sealing and cutting devices, which shortens the entire equipment and ensures that the cutting is in the middle of the sealing. The product is more beautiful, which saves production costs for the equipment manufacturer. In addition, the shortened length of the equipment also reduces the length of the production line, the product transmission efficiency is higher, and the production efficiency is improved. The hot pressing protrusion 301 and the cutting knife 302 have been disclosed in a sealing and cutting integrated knife holder with the authorization number "CN 219383049 U" and will not be repeated in this solution.

[0035] In this solution, the top surface of the cutting knife 302 extends out of the mounting groove and is adapted to the sedimentation tank 401. When cutting, the cutting knife 302 is inserted into the sedimentation tank 401, so that the adjacent menstrual pants 9 can be completely cut without the need for secondary processing, thereby improving production efficiency.

[0036] like Figure 1 As shown, a tensioning roller 5 is provided on the feeding side of the anvil roller 4 , and the tensioning roller 5 generates tensioning force on the menstrual pants 9 to ensure that the menstrual pants 9 are adsorbed on the upper surface of the anvil roller 4 .

[0037] Specifically, during the trouser body transmission process, the trouser body is tensioned by the tensioning roller 5, and the top of the trouser body is adsorbed by the anvil roller 4. At this time, the position of the trouser body remains unchanged, ensuring the stability of the trouser body and preventing the trouser body from generating tension during the first hot pressing and sealing process. The incision is located in the middle of the two hot pressing seals, making the two sides of the menstrual pants 9 symmetrical after cutting, thereby improving the quality of the menstrual pants 9.

[0038] In order to further improve the practicability of the device and increase production efficiency, Figure 1 and Figure 3 As shown, a material transfer assembly 6 and a conveying assembly 7 are provided on the discharge side of the anvil roller 4;

[0039] The material transfer assembly 6 includes a rotating shaft 601 and a T-shaped suction plate 602. A plurality of second suction holes are provided on the T-shaped suction plate 602. A plurality of through holes 603 connected to the second suction holes are provided on the end surface of the rotating shaft 601.

[0040] It can be understood that an air distribution disk (not shown in the figure) is provided on the outside of the rotating shaft 601 and the anvil roller 4, and the air distribution disk is connected to the through hole 603. The air distribution disk is used to connect the negative pressure generated by the external fan to the second adsorption hole and the first adsorption hole through the suction pipe (not shown in the figure), thereby achieving adsorption of the menstrual pants 9 and the trouser body. The above is the existing technology and will not be repeated in this solution.

[0041] It can be understood that the conveying assembly 7 conveys the cut menstrual pants 9, and the conveying assembly 7 is a common conveying assembly on the market consisting of a rotating shaft and a conveyor belt.

[0042] Specifically, after the trouser body is cut into menstrual pants 9, the menstrual pants 9 continue to rotate along the anvil roller 4. When the menstrual pants 9 move to the side of the anvil roller 4, the side of the T-shaped suction plate 602 contacts the menstrual pants 9, and the menstrual pants 9 are adsorbed by the T-shaped suction plate 602, thereby taking the menstrual pants 9 away from the anvil roller 4. When the T-shaped suction plate 602 rotates to the top of the conveying component 7, the controller controls the fan to stop or control the fan to reverse. At this time, the menstrual pants 9 fall onto the conveyor belt of the conveying component 7 for transportation and enter the next process.

[0043] In order to ensure the adsorption force on the top of the pressure roller 2 and prevent the trouser body from separating from the anvil roller 4, a barrier 8 is provided at the bottom of the anvil roller 4. The barrier 8 includes a rotating rod 801 and a surrounding plate 802. The distance between the surrounding plate 802 and the anvil roller 4 is 0.5-1mm. Slopes 803 are formed on both sides of the surrounding plate 802 to avoid interfering with the movement of the menstrual pants 9.

[0044] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the accompanying embodiments and their equivalents.
