Description

Technical Field

[0001] The utility model belongs to the technical field of hygiene product production equipment, and particularly relates to a production device for exhausting and sealing hygiene products. Background Art

[0002] In the current production of hygiene products, especially in the production of sanitary napkins, after a series of production processes, they need to be bagged and individually packaged separately for users to disassemble and use once. When individually packaging, the sanitary napkins are put into bags and sealed. If the air in the bags is not exhausted at this time, bags with too much remaining air will not only affect the shelf life of the sanitary napkins but also occupy a large amount of space in the box. Filling more individually packaged sanitary napkins in a single box can reduce the overall transportation cost and lower the cost input of the enterprise. However, today's exhaust equipment needs to enter the next sealing process to complete the sealing after exhausting the air in the bags. During this period, air will flow into the bags, resulting in too much air remaining in the bags. In addition, the size specifications of sanitary napkins are not the same, and today's exhaust equipment does not have a corresponding adjustment function, causing insufficient exhaust during packaging for too thin products and damage to products due to excessive extrusion during exhaust for too thick products. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides a production device for exhausting and sealing hygiene products. After the products are sent into the exhaust assembly for exhausting the air in the bags, they are immediately sent into the sealing assembly to seal the bags, shortening the time interval between the two processes and avoiding too much air entering the bags. At the same time, through adjustable pressing rollers, the gap between them is changed to adapt to products of different thicknesses for exhausting.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A production device for exhausting and sealing hygiene products includes an exhaust assembly and a sealing assembly. The exhaust assembly includes a bracket and two groups of conduction members. The two groups of conduction members are arranged corresponding to each other up and down on the bracket; the sealing assembly includes a support frame and two groups of sealing members. The two groups of sealing members are arranged corresponding to each other up and down and are rotatably connected to the support frame. The gap between the two groups of conduction members and the gap between the two groups of sealing members are horizontally aligned with each other.

[0006] The conduction member includes a driving motor, a driving roller, a driven roller, a conveyor belt, a pressing roller, a fixing plate, and an adjusting component. The conveyor belt is sleeved on the driving roller and the driven roller. The pressing roller is arranged inside the conveyor belt. The driving roller, the driven roller, and the pressing roller are all rotatably connected to the fixing plate. The driving motor is arranged on the fixing plate and its output end is connected to the driving roller. The fixing plate is connected to the bracket. The two groups of pressing rollers are arranged corresponding to each other up and down.

[0007] The adjusting member is arranged on the fixing plate of the upper conduction member. The adjusting member includes an adjusting hole, a spring, an adjusting seat, a connecting rod, a connecting cylinder and a connecting seat. The adjusting hole is arranged on the fixing plate. The rotating end of the pressing roller passes through the adjusting hole and extends out of the fixing plate. An installation groove is arranged on the lower end surface of the adjusting hole. The spring is embedded in the installation groove and abuts upward against the lower part of the rotating end. The adjusting seat is arranged on the fixing plate. A stud is threadedly connected in the threaded hole on the adjusting seat. The lower end surface of the stud abuts against the upper part of the rotating end. The connecting cylinder is connected to the bracket through the connecting seat. The output end of the connecting cylinder is connected to the fixing plate of the upper conduction member through the connecting rod. The connecting rod extends upward and inclines away from the sealing component.

[0008] The sealing component includes a servo motor and a sealing roller. The servo motor is arranged on the support frame. The output end of the servo motor drives the sealing roller rotatably connected to the support frame to rotate around its axis. Axially distributed heat sealing heads are arranged on the outer side wall of the sealing roller. The two groups of heat sealing heads abut against each other at the gap between the two groups of sealing rollers when rotating to the gap.

[0009] For the production device for exhausting and sealing sanitary products with this structure, the gap between the two groups of conduction members is horizontally aligned and corresponding to the gap between the two groups of sealing members. Therefore, when the two groups of conduction members are fed into the packaging bag from the conveyor belt, the sanitary napkins that have been loaded in sequence and separated at intervals will first be squeezed by the gap between the two groups of conduction members, so as to expel excessive air backward, avoiding too much air remaining in the packaging bag when it is fed into the sealing component. Since the distance between the two groups of conduction members and the two groups of sealing members is very short, the packaging bag can be sealed immediately in a short time, effectively preventing air from escaping into the packaging bag, thus ensuring its packaging effect. How the packaging bag carrying the sanitary napkins is fed between the two groups of conduction members through the conveyor belt belongs to the prior art, so there is no need to elaborate too much on how to achieve the effect of interval loading and conveying here.

[0010] In order to achieve the extrusion of air inside the packaging bag through the conduction member, the driving roller is driven by the driving motor to rotate, thereby driving the conveyor belt between the driving roller and the driven roller. The transmission speed is coordinated with the speed of the packaging bag entering the conveyor belt to ensure the transmission continuity during the air extrusion process. For the pressing rollers inside the conveyor belt, the upper and lower corresponding pressing rollers are adjusted by adjusting the downward displacement distance of the upper pressing roller to adapt to the exhaust effect of sanitary napkins with different thicknesses. Therefore, adjustment holes are provided on the fixed plate. The rotating end of the pressing roller is inserted into the adjustment hole. The lower part of the rotating end is supported by a spring, while the upper part is subjected to the downward pressure of the stud on the adjustment seat. Therefore, when it is necessary to adapt to a thinner sanitary napkin, the stud is turned to press down on the rotating end, and the rotating end synchronously presses down the spring, thereby reducing the gap between the two groups of pressing rollers; when it is necessary to adapt to a thicker sanitary napkin, the stud is turned to loosen the pressing force on the rotating end, and the rotating end moves upward under the supporting force of the spring, thereby increasing the gap between the two groups of pressing rollers.

[0011] Since the equipment needs to be overhauled, if the small gap between the two groups of conduction members is always maintained, it will increase the difficulty of overhaul. Therefore, the upper conduction member is displaced up and down by the start of the connecting cylinder to increase the distance between the two groups of conduction members, thereby facilitating the overhaul. Since the distance between the conduction member and the sealing member is very short, the driving roller is relatively large, the distance between the driven roller and the sealing member is relatively close and its size is small, so as to shorten the distance from the sealing member. At this time, for the movable upper conduction member, if it moves vertically up and down, it will easily cause the driven roller to hit the support frame or the sealing roller, resulting in damage to the equipment. Therefore, the connecting rod is set to extend upward and incline away from the sealing assembly. When the upper conduction member moves up and down, it will increase the distance between the driven roller and the sealing member, thereby avoiding the possibility of damage.

[0012] The sealing member consists of two groups of sealing rollers that are parallel to each other. Driven by the servo motor, they rotate at the same speed. The hot sealing heads on the sealing rollers abut against each other when they rotate to the minimum gap between the two groups of sealing rollers. Therefore, the packaging bag is sealed when it passes between the two groups of hot sealing heads. Each time the two groups of hot sealing heads abut against each other, it is exactly the interval between each group of sanitary napkins. Therefore, by adjusting the speed of the servo motor, it can well adapt to the interval sealing between each group of sanitary napkins.

[0013] Furthermore, the sealing assembly further includes an adjustment member. The adjustment member includes an adjustment seat and an adjustment cylinder. The adjustment seat is detachably connected to the support frame. The adjustment cylinder is arranged on the adjustment seat. The output end of the adjustment cylinder penetrates downward through the adjustment seat and is connected to the servo motor of the upper sealing member.

[0014] Compared with the prior art, the advantages of the present utility model are as follows: By means of two sets of conduction members and two sets of sealing members with a very short distance, the packaging bag can be sealed immediately in a short time, effectively avoiding air from entering the packaging bag, thereby ensuring its packaging effect. By adjusting the downward displacement distance of the upper pressing roller, the exhaust effect of sanitary napkins with different thicknesses can be adapted. Through the setting of the conduction member that can be displaced up and down, subsequent maintenance is facilitated, and the disassembly and assembly of the equipment are reduced. By adjusting the speed of the servo motor, it can well adapt to the hot seal head on the sealing roller to perform interval sealing between each group of sanitary napkins.

[0025] The following will describe the detailed implementation manners of the present utility model with reference to the accompanying drawings:

[0026] As Figure 1-7 shown, a production device for exhausting and sealing sanitary products includes an exhaust assembly 1 and a sealing assembly 2. The exhaust assembly 1 includes a bracket 11 and two sets of conduction members 12. The two sets of conduction members 12 are arranged corresponding to each other vertically and are disposed on the bracket 11. The sealing assembly 2 includes a support frame 21 and two sets of sealing members 22. The two sets of sealing members 22 are arranged corresponding to each other vertically and are rotatably connected to the support frame 21. The gaps between the two sets of conduction members 12 and the gaps between the two sets of sealing members 22 are horizontally aligned with each other.

[0027] The conduction member 12 includes a driving motor 121, a driving roller 122, a driven roller 123, a conveyor belt 124, a pressing roller 125, a fixed plate 126 and an adjusting member 127. The conveyor belt 124 is sleeved on the driving roller 122 and the driven roller 123. The pressing roller 125 is disposed inside the conveyor belt 124. The driving roller 122, the driven roller 123 and the pressing roller 125 are all rotatably connected to the fixed plate 126. The driving motor 121 is disposed on the fixed plate 126 and its output end is connected to the driving roller 122. The fixed plate 126 is connected to the bracket 11. The two sets of pressing rollers 125 are arranged corresponding to each other vertically.

[0028] The adjusting member 127 is arranged on the fixing plate 126 of the upper conductive member 12. The adjusting member 127 includes an adjusting hole 1271, a spring 1272, an adjusting seat 1273, a connecting rod 1277, a connecting cylinder 1278 and a connecting seat 1279. The adjusting hole 1271 is arranged on the fixing plate 126. The rotating end 1251 of the pressing roller 125 passes through the adjusting hole 1271 and extends out of the fixing plate 126. An installation groove 1274 is arranged on the lower end surface of the adjusting hole 1271. The spring 1272 is embedded in the installation groove 1274 and abuts upward against the lower part of the rotating end 1251. The adjusting seat 1273 is arranged on the fixing plate 126. A stud 1276 is in threaded connection with a threaded hole 1275 on the adjusting seat 1273. The lower end surface of the stud 1276 abuts against the upper part of the rotating end 1251. The connecting cylinder 1278 is connected to the bracket 11 through the connecting seat 1279. The output end of the connecting cylinder 1278 is connected to the fixing plate 126 of the upper conductive member 12 through the connecting rod 1277. The connecting rod 1277 extends upward and is inclined away from the sealing component 2.

[0029] The sealing member 22 includes a servo motor 221 and a sealing roller 222. The servo motor 221 is arranged on the support frame 21. The output end of the servo motor 221 drives the sealing roller 222 rotatably connected to the support frame 21 to rotate around its axis. Axially distributed heat sealing heads 223 are arranged on the outer side wall of the sealing roller 222. The two groups of heat sealing heads 223 abut against each other at the gap between the two groups of sealing rollers 222 when rotating.

[0030] Further, the sealing component 2 further includes an adjusting member 224. The adjusting member 224 includes an adjusting seat 2241 and an adjusting cylinder 2242. The adjusting seat 2241 is detachably connected to the support frame 21. The adjusting cylinder 2242 is arranged on the adjusting seat 2241. The output end of the adjusting cylinder 2242 penetrates downward through the adjusting seat 2241 and is connected to the servo motor 221 of the upper sealing member 22.

[0031] The working mode of the present utility model is described as follows:

[0032] For the production device of the exhaust sealing of sanitary products adopting this structure, the gap between the two groups of conduction members 12 is horizontally aligned and corresponding to the gap between the two groups of sealing members 22. Therefore, when the two groups of conduction members 12 are fed into the packaging bag from the conveyor belt, the sanitary napkins that have been loaded in sequence and spaced apart will first be squeezed by the gap between the two groups of conduction members 12, so as to expel the excessive air backward, avoiding too much air remaining in the packaging bag when it is fed into the sealing member 22. Since the distance between the two groups of conduction members 12 and the two groups of sealing members 22 is very short, the packaging bag can be sealed immediately in a short time, effectively preventing air from escaping into the packaging bag, thus ensuring its packaging effect. Here, how the packaging bag carrying the sanitary napkins is fed between the two groups of conduction members 12 belongs to the prior art, so there is no need to elaborate too much on how to achieve the effect of intermittent loading and conveying here.

[0033] In order to realize the extrusion of air in the packaging bag through the conduction member 12, the driving roller 122 is driven to rotate by the driving motor 121, so as to drive the conveyor belt 124 between the driving roller 122 and the driven roller 123, and its transmission speed is coordinated with the speed of the packaging bag entering from the conveyor belt to ensure the transmission continuity during the process of expelling air. The pressing rollers 125 in the conveyor belt 124, the upper and lower corresponding pressing rollers 125, are used to adapt to the exhaust effect of sanitary napkins with different thicknesses by adjusting the downward movement distance of the upper pressing roller 125. Therefore, an adjustment hole 1271 is provided on the fixing plate 126, and the rotating end 1251 of the pressing roller 125 is inserted into the adjustment hole 1271. The lower part of the rotating end 1251 is supported by the spring 1272, and the upper part is pressed by the stud 1276 on the adjustment seat 1273. Therefore, when it is necessary to adapt to sanitary napkins with a thinner thickness, the stud 1276 is screwed to press down on the rotating end 1251, and the rotating end 1251 synchronously presses down the spring 1272, thus reducing the gap between the two groups of pressing rollers 125; when it is necessary to adapt to sanitary napkins with a thicker thickness, the stud 1276 is screwed to loosen the pressing force on the rotating end 1251, and the rotating end 1251 moves upward under the supporting force of the spring 1272, thus increasing the gap between the two groups of pressing rollers 125.

[0034] Since the equipment needs to be overhauled, if the smaller gap between the two sets of conducting members 12 is maintained all the time, it will increase the difficulty of overhaul. Therefore, the upper conducting member 12 is displaced up and down by the activation of the connecting cylinder 1278 to increase the distance between the two sets of conducting members 12, thus facilitating the overhaul. Since the distance between the conducting member 12 and the sealing member 22 is very short, the driving roller 122 is relatively large, and the driven roller 123 is close to the sealing member 22 and its size is small, so as to shorten the distance from the sealing member 22. At this time, for the movable upper conducting member 12, if it is displaced vertically up and down, it is very likely that the driven roller 123 will hit the support frame 21 or the sealing roller 222, causing damage to the equipment. Therefore, the connecting rod 1277 is set to extend upward and incline away from the sealing assembly 2. When the upper conducting member 12 is displaced up and down, the distance between the driven roller 123 and the sealing member 22 will be increased, thus avoiding the possibility of damage.

[0035] The sealing member 22 is rotated at the same speed by two sets of parallel sealing rollers 222 driven by the servo motor 221. The heat sealing heads 223 on the sealing rollers 222 are in contact with each other when rotating to the minimum gap between the two sets of sealing rollers 222. Therefore, the packaging bag is sealed when passing between the two heat sealing heads 223. Each time the two heat sealing heads 223 are in contact with each other, it is exactly the interval between each group of sanitary napkins. Therefore, by adjusting the speed of the servo motor 221, it can well adapt to the interval sealing between each group of sanitary napkins.

[0036] Similarly, the sealing assembly 2 also needs to be overhauled. Therefore, an adjustment seat 2241 is added to the support frame 21, and the upper servo motor 221 is driven to move horizontally up and down by the adjustment cylinder 2242, so as to increase the distance between the two sets of sealing rollers 222, facilitating the staff to overhaul it.

[0037] The beneficial effects of the present utility model are as follows: The two sets of conducting members 12 with a very short distance and the two sets of sealing members 22 can seal the packaging bag immediately in a short time, effectively avoiding air from entering the packaging bag, thus ensuring its packaging effect. By adjusting the downward displacement distance of the upper pressing roller 125, it can adapt to the exhaust effect of sanitary napkins with different thicknesses. By setting the conducting member 12 that can be displaced up and down, it is convenient for subsequent overhaul and reduces the disassembly and assembly of the equipment. By adjusting the speed of the servo motor 221, it can well adapt to the interval sealing of the heat sealing heads 223 on the sealing rollers 222 for each group of sanitary napkins.

[0038] 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 described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
