Description

Technical Field

[0001] This utility model relates to the technical field of diaper folding equipment, and in particular to a diaper folding device. Background Technology

[0002] Disposable diapers are a type of disposable hygiene product, mainly used for infants and adults. During the production of disposable diapers, they need to be folded to facilitate packaging and shipping.

[0003] For example, CN222809015U discloses an auxiliary folding device for diaper production. The described scheme includes an operating table, a positioning device, a conveyor belt, and a folding shovel. The folding shovel falls during the diaper conveying process, and the front end of the diaper slides upward along the folding shovel. After sliding a certain distance, the folding shovel folds the front end and the rear end of the diaper together to complete the folding.

[0004] However, the operators discovered the following problem during production: Although the positioning device of the equipment can be used to produce diapers of various sizes, when folding diapers of the same size, because the outer layer of the diaper is made of waterproof plastic film material, and the core part of the diaper is relatively heavy while the edges are relatively light and easily deformed, the outer plastic film of the core part of the diaper tends to stick to the conveyor belt when the folded diaper is conveyed on the conveyor belt. The folding shovel head needs to press down on the conveyor belt to make the diaper move up along the folding shovel. This will cause friction on the conveyor belt and accelerate the wear and tear of the conveyor belt. Utility Model Content

[0005] The purpose of this utility model is to provide a diaper folding device to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] First, this utility model provides a diaper folding device, comprising:

[0008] A machine tool having an upward-facing slot that runs through the machine tool in a left-right direction;

[0009] The conveying assembly includes a conveyor belt and two conveyor rollers. The two conveyor rollers are disposed in the groove of the machine tool and are rotatably connected to the machine tool. The conveyor belt is connected to the conveyor rollers. The surface of the conveyor belt is provided with several rows of evenly spaced first through holes. Each row of first through holes is evenly distributed along the width direction of the conveyor belt.

[0010] A guide assembly is located on the left side of the machine tool, the guide assembly is connected to the machine tool, and the guide assembly is positioned above the conveyor belt;

[0011] A folding assembly is located to the right of the guide assembly. The folding assembly includes a folding shovel, a bracket, and a telescopic mechanism. The bracket is connected to the machine base. The telescopic mechanism is connected to the downward side of the bracket. The folding shovel is connected below the telescopic mechanism. A gap is left between the lower end of the folding shovel and the surface of the conveyor belt.

[0012] An air outlet mechanism has an air inlet and an air outlet. The air inlet of the air outlet mechanism is connected to an air source. The air outlet of the air outlet mechanism is located between the folding assembly and the guiding assembly. The air outlet of the air outlet mechanism is located in the area enclosed by the conveyor belt. The air outlet of the air outlet mechanism discharges air upwards.

[0013] A motion sensor switch is connected to the bracket and is located on the left side of the folding assembly.

[0014] By configuring the conveyor belt with the first through-hole, the adhesion between the outer plastic film of the core portion of the diaper to be folded and the conveyor belt is reduced. Secondly, because an air outlet mechanism is installed in the space enclosed by the conveyor belt, with its outlet facing upwards and its inlet connected to an air source, the gas is transmitted through the row of holes on the conveyor belt to the top of the conveyor belt and acts on the diaper to be folded. This causes one edge of the diaper to be folded to rise upwards, allowing the folding spatula to smoothly move one end of the diaper upwards without contacting the conveyor belt, ultimately completing the folding. In this design, the folding spatula does not rub against the conveyor belt, thus not accelerating conveyor belt wear. Although the conveyor belt surface in this design has several evenly spaced first through-holes, since the conveyor belt surface carries diapers, which are very lightweight, these first through-holes do not actually accelerate the aging or breakage of the conveyor belt.

[0015] Specifically, the inductive switch is responsible for detecting the position of the diaper to be folded and connecting the air source. When the diaper is being conveyed to the folding assembly, the inductive switch detects that one end of the diaper is about to reach the folding spatula. At this time, the inductive switch sends a signal to turn on the air source, and gas is ejected from the air outlet of the air outlet mechanism. Gas passes through the holes in the conveyor belt and acts on the front end of the diaper, causing the front end of the diaper to rise. Most of the diaper remains on the conveyor belt. After a set time, the inductive switch turns off the air source. The diaper then continues to move upwards along the folding spatula until it is folded in half. After folding, the folding spatula moves upwards, allowing the folded diaper to move to the next process. It should be noted that the air outlet mechanism needs to distribute the gas evenly across the outer plastic film of the diaper to prevent displacement. Additionally, the air outlet of the air outlet mechanism should be positioned relatively close to the spatula head in the diaper conveying direction, allowing the front part of the diaper to rise and facilitating its movement upwards along the folding spatula under the action of the conveyor belt. The interval between two adjacent rows of first through holes on the conveyor belt should be set to be smaller than the diameter of the air outlet, so as to ensure that the gas ejected from the air outlet can pass through the conveyor belt during the rotation of the conveyor belt.

[0016] As an extension of the above solution, the air outlet mechanism includes an air outlet pipe and an air outlet nozzle. The air outlet nozzle faces upwards, and the center of the air outlet nozzle is an air storage chamber. Multiple air outlet nozzles are connected above the air storage chamber and communicate with the air storage chamber. The air outlet pipe is connected below the air storage chamber and is connected to an air source. By connecting one end of the air outlet pipe to the air source and the other end to the air storage chamber, and by setting multiple air outlet nozzles on the air storage chamber, the air outlet nozzles can deliver air more evenly, preventing the diaper to be folded from shifting during the blowing process.

[0017] In some scenarios, the following configuration can be made: the air storage cavity is a rectangular cavity with an overall thickness less than its overall length, and its length extends in the same direction as the width of the conveyor belt. Multiple air outlet nozzles are connected to the upper surface of the air storage cavity. Each air outlet nozzle is a cylindrical tube, and its inner bore communicates with the air storage cavity. The number of air outlet nozzles is the same as the number of first through holes evenly arranged along the width of the conveyor belt. Furthermore, the distribution of the air outlet nozzles is consistent with the distribution of the first through holes on the conveyor belt. An air outlet pipe is connected to the lower part of the air storage cavity, and this pipe is connected to an air source. The gas flow rate entering the air storage cavity should be greater than or equal to the sum of the gas flow rates of the multiple air outlet nozzles, and the inner diameter of each air outlet nozzle should be consistent.

[0018] As an extension of the above solution, the inner diameter of the air nozzle is the same as the diameter of the first through hole. Although the gas will act on the gap between the two rows of first through holes at a certain moment of conveyor belt rotation, as mentioned in the previous solution, the gap between the two rows of first through holes is smaller than the diameter of the first through hole. Therefore, during the gas injection process, gas can always pass through the first through hole, and the impact on the conveyor belt is minimized. Furthermore, when the air nozzle is aligned with the first through hole, the gas coverage area on the outer layer of the diaper is maximized, and the diaper is more stably lifted by the gas.

[0019] As an extension of the above solution, the inner diameter of the outlet pipe is larger than the inner diameter of the outlet nozzle. This ensures that the flow rate of gas passing through the gas storage chamber is greater than the flow rate of gas from the outlet nozzle.

[0020] As an extension of the above solution, the air storage chamber has a first air inlet pipe extending downwards, and a second air inlet pipe extending horizontally from the end of the first air inlet pipe. The second air inlet pipe is connected to the air outlet of the air outlet pipe, which horizontally penetrates the machine tool, and the air inlet of the air outlet pipe is connected to the source. This arrangement simplifies the installation of the air outlet mechanism.

[0021] As an extension of the above solution, the air outlet pipe is a circular pipe, and the outer wall of the connection between the air outlet pipe and the second air inlet pipe is provided with a groove. The inner wall of the second air inlet pipe extends inward with protruding teeth, which are adapted to the groove. This arrangement can prevent displacement between the air outlet nozzle and the air outlet pipe during operation.

[0022] As an extension of the above solution, the bracket is equipped with a slider, and the sensor switch is connected to a slide rail, with the slide rail slidably connected to the slider. Connecting the sensor switch to the bracket via a sliding connection allows for easy adjustment of the sensor switch's position. Furthermore, the slider is positioned at the top of the bracket, and the sensor switch is positioned above the conveyor belt.

[0023] As an extension of the above solution, a traction handle is connected to the slide rail. This arrangement facilitates adjustment of the relative position of the inductive switch.

[0024] As an extension of the above solution, the guiding assembly includes two symmetrically arranged guide blocks and a telescopic motor. The telescopic motor is connected to the opposite sides of the two guide blocks, causing the two guide blocks to face each other or move apart. The telescopic motor is connected to the machine base. Compared with the prior art, this arrangement allows for more consistent relative displacement between the two guide blocks and facilitates installation.

[0025] As an extension of the above solution, both guide blocks are regular triangular prisms with their inclined surfaces facing each other. One right-angled surface of each guide block is vertical to the machine platform and connected to the telescopic motor. Because the edges of the diaper are relatively soft and lighter than the core portion, in existing technologies, the edges of the diaper may deform when passing over the guide blocks, resulting in poor positioning. However, this solution ensures that during transport, the side edges of the diaper rise upwards under the action of the inclined surfaces of the guide blocks, allowing the core portion of the diaper to contact the corner of the regular triangular prism guide block. Compared to existing technologies, this solution provides better positioning of the diaper. Attached Figure Description

[0035] Reference Figures 1 to 3 The following are several embodiments of a diaper folding device according to the present invention.

[0036] like Figures 1 to 2 As shown, a diaper folding device includes:

[0037] Machine base 100, the machine base 100 having an upward-facing slot that extends through the machine base 100 in the left-right direction;

[0038] The conveying assembly 300 includes a conveyor belt 301 and two conveyor rollers 302. The two conveyor rollers 302 are disposed in the groove of the machine base 100 and are rotatably connected to the machine base 100. The conveyor belt 301 is connected to the conveyor rollers 302. The surface of the conveyor belt 301 is provided with several rows of evenly spaced first through holes 600. Each row of first through holes 600 is evenly distributed along the width direction of the conveyor belt 301.

[0039] A guide component 200 is connected to the machine base 100 and is located above the conveyor belt 301;

[0040] The folding assembly 400 is located to the right of the guide assembly 200. The folding assembly 400 includes a folding shovel 401, a bracket 402, and a telescopic mechanism 403. The bracket 402 is connected to the machine base 100. The downward side of the bracket 402 is connected to the telescopic mechanism 403. The folding shovel 401 is connected below the telescopic mechanism 403. A gap is left between the lower end of the folding shovel 401 and the surface of the conveyor belt 301.

[0041] An air outlet mechanism 500 has an air inlet and an air outlet. The air inlet of the air outlet mechanism 500 is connected to an air source, and the air outlet of the air outlet mechanism 500 is located between the folding assembly 400 and the guiding assembly 200. The air outlet of the air outlet mechanism 500 is located in the area enclosed by the conveyor belt 301, and the air outlet of the air outlet mechanism 500 discharges air upwards.

[0042] A sensor switch 501 is connected to the bracket 402 and is located on the left side of the folding assembly 400.

[0043] By configuring the conveyor belt 301 with a first through hole 600, the adhesion between the outer plastic film of the core portion of the diaper to be folded and the conveyor belt 301 is reduced. Secondly, because an air outlet mechanism 500 is provided in the space enclosed by the conveyor belt 301, with its outlet facing upwards and its inlet connected to an air source, when the air source is ejected through the air outlet mechanism 500, the gas is transmitted through the row of holes on the conveyor belt 301 to the area above the conveyor belt 301 and acts on the diaper to be folded. This causes one edge of the diaper to be folded to rise upwards, allowing the folding spatula 401 to smoothly move one end of the diaper upwards along the folding spatula 401 without contacting the conveyor belt 301, ultimately completing the folding. In this design, the folding spatula 401 does not rub against the conveyor belt 301, thus not accelerating the wear and tear on the conveyor belt 301. Although the conveyor belt in this solution has several evenly spaced first through holes, since the conveyor belt carries diapers, which are very lightweight, these first through holes will not actually accelerate the aging and breakage of the conveyor belt.

[0044] Specifically, the induction switch 501 is responsible for detecting the position of the diaper to be folded and connecting to the air source. When the diaper is being conveyed to the folding assembly 400, the induction switch 501 detects that one end of the diaper is about to reach the folding spatula 401. At this time, the induction switch 501 activates the air source, and gas is ejected from the air outlet mechanism 500, passing through the holes in the conveyor belt 301 and acting on the front end of the diaper to be folded, causing the front end of the diaper to rise. Most of the diaper remains on the conveyor belt. After a set time has elapsed, the induction switch 501 deactivates the air source. The diaper then continues to move upwards along the folding spatula until it is folded in half. After folding, the folding spatula 401 moves upwards, allowing the folded diaper to move to the next process. It should be noted that when the air outlet mechanism 500 emits gas, it must ensure that the gas acts evenly on the outer plastic film of the diaper to prevent displacement of the diaper. In addition, the position of the air outlet in the conveying direction should be relatively close to the head of the folding shovel 401, so that the front part of the diaper can rise, facilitating the upward movement of the diaper along the folding shovel 401 driven by the conveyor belt 301. The interval between two adjacent rows of first through holes 600 on the conveyor belt 301 should be set to be smaller than the diameter of the air outlet of the air outlet mechanism 500, so as to ensure that the gas ejected from the air outlet can pass through the conveyor belt during the rotation of the conveyor belt 301.

[0045] like Figure 2 and Figure 3 As shown, in some embodiments, the air outlet mechanism 500 includes an air outlet pipe 502 and an air outlet nozzle 503. The air outlet nozzle 503 faces upwards, and the middle of the air outlet nozzle 503 is an air storage chamber 5031. Multiple air outlet nozzles 5032 are connected above the air storage chamber 5031 and communicate with the air storage chamber 5031. The air outlet pipe 502 is connected below the air storage chamber 5031 and is connected to an air source. By connecting one end of the air outlet pipe 502 to the air source and the other end to the air storage chamber 5031, and by providing multiple air outlet nozzles 5032 on the air storage chamber 5031, the air outlet mechanism 500 can deliver air more evenly, preventing the diaper to be folded from shifting during the blowing process.

[0046] In some scenarios, the following configuration can be made: the air storage cavity 5031 is a rectangular cavity with an overall thickness less than its overall length, and its length extends in the same direction as the width of the conveyor belt. Multiple air outlet nozzles 5032 are connected to the upper surface of the air storage cavity 5031. Each air outlet nozzle 5032 is a cylindrical tube, and its inner hole communicates with the air storage cavity 5031. The number of air outlet nozzles 5032 corresponds to the number of the first through holes 600 evenly arranged along the width of the conveyor belt. The quantities are the same, and the distribution of the air outlet nozzles 5032 is consistent with the first through hole 600 provided on the conveyor belt. An air outlet pipe 502 is connected to the lower part of the air storage chamber 5031. The air outlet pipe 502 is connected to the air source. The gas flow rate entering the air storage chamber 5031 should be greater than or equal to the sum of the gas flow rates of the plurality of air outlet nozzles 5032. Furthermore, the inner diameter of each air outlet nozzle 5032 should be consistent, and the inner diameter of the air outlet nozzle 5032 is the same as the diameter of the first through hole 600.

[0047] Although gas may act on the gap between the two rows of first through holes 600 at a certain moment of rotation of the conveyor belt 301, as mentioned in the aforementioned scheme, the gap between the two rows of first through holes 600 is smaller than the diameter of the first through holes 600. Therefore, during the gas injection process, gas can always pass through the first through holes 600, and the impact on the conveyor belt 301 is minimal. Furthermore, when the air nozzle 5032 is aligned with the first through hole 600, the coverage area of ​​the gas acting on the outer layer of the diaper is maximized, and the gas will blow the diaper more stably.

[0048] The inner diameter of the air outlet pipe 502 is larger than the inner diameter of the air outlet nozzle 5032. This ensures that the flow rate of the gas passing through the air storage chamber 5031 is greater than the flow rate of the gas outlet nozzle 5032.

[0049] In some embodiments, the air storage chamber 5031 has a first air inlet pipe 5033 extending downwards, and a second air inlet pipe 5034 extending horizontally from the end of the first air inlet pipe 5033. The second air inlet pipe 5034 is connected to the air outlet of the air outlet pipe 502, which horizontally penetrates the machine base 100. The air inlet of the air outlet pipe 502 is connected to the source. The air outlet pipe 502 is a circular pipe, and the outer wall of the connection between the air outlet pipe 502 and the second air inlet pipe 5034 has a groove. The inner wall of the second air inlet pipe 5034 has protruding teeth extending inwards, which are adapted to the groove. This arrangement can prevent displacement between the air outlet nozzle 503 and the air outlet pipe 502 during operation, and makes the installation of the air outlet mechanism 500 simpler.

[0050] In some embodiments, the bracket 402 is provided with a slider 4021, and the sensor switch 501 is connected to a slide rail 4022, with the slide rail 4022 slidably connected to the slider 4021. Connecting the sensor switch 501 to the bracket 402 via this slidable connection facilitates easy adjustment of its position. Further, the slider 4021 is positioned at the top of the bracket 402, and the sensor switch 501 is positioned above the conveyor belt 301. A traction handle 4023 is connected to the slide rail 4022. This arrangement facilitates adjustment of the relative position of the sensor switch 501.

[0051] In some embodiments, the guiding assembly 200 includes two symmetrically arranged guide blocks 201 and a telescopic motor 202. The telescopic motor 202 is connected to the opposite sides of the two guide blocks 201, causing the two guide blocks 201 to face each other or move apart. The telescopic motor 202 is connected to the machine base 100. Compared with the prior art, this arrangement allows for more consistent relative displacement between the two guide blocks 201 and facilitates installation.

[0052] Both guide blocks 201 are regular triangular prisms, with their inclined surfaces facing each other. One right-angled surface of each guide block 201 is vertical to the machine base 100 and connected to the telescopic motor 202. Because the edges of the diaper are relatively soft and lighter than the core portion, in existing technologies, the edges of the diaper may deform when passing over the guide blocks 201, resulting in poor positioning. However, this design ensures that during transport, the side edges of the diaper rise upwards under the influence of the inclined surfaces of the guide blocks 201, allowing the core portion of the diaper to contact the corners of the triangular prism guide blocks 201. Compared to existing technologies, this design provides better positioning of the diaper.

[0053] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
