Description

Technical Field

[0001] The present invention particularly relates to an all-in-one machine for punching, folding and packaging bed sheet patches. Background Art

[0002] In the medical field, when a patient suffers a localized skin injury, such as a back injury, surgery or medication is required. At this time, a patch with through holes is attached to the injured area, such as the back. The position of the through holes will expose the injured area, so that the injured area can be treated without infection. In the production process, such patches with through holes are produced in rolls, and rolled fabrics are commonly known as bed sheets. The manufacturing steps generally involve first sticking one side of the double-sided patch to the bed sheet, then punching the holes, and then folding it. Therefore, automated production equipment is required to implement the above process.

[0003] The invention patent disclosure document with publication number "CN114506727A" discloses a bed sheet punching and patching machine, which is mainly composed of a rewinding mechanism, a patching mechanism, a punching mechanism, a first folding mechanism, and a second folding mechanism. It can realize the patching and punching operations on the bed sheet, and can also fold the bed sheet.

[0004] However, the above-mentioned sheet punching and placement machine has the following defects:

[0005] First, the second folding mechanism includes multiple sets of conveyor belts, and a set of inserting plates is provided between each two adjacent sets of conveyor belts. Figure 1 9-13 show the folding method of the second folding mechanism. During folding, the insert plate pushes the sheet downward. Each time the sheet moves under a different insert plate, the folding method is repeated to complete the folding. This folding mechanism mainly utilizes the insert plate and the gap between the two sets of conveyor belts to fold the sheet. During this process, the force of the insert plate on the sheet and the weight of the sheet itself are both vertically downward, and the entire sheet will move during the folding process. The sheet will inevitably wrinkle during the folding process, and it is impossible to ensure that each layer of the sheet is flat, which means that the folding effect is poor.

[0006] Secondly, the aforementioned sheet punching and placement machine suffers from low production efficiency. The second folding mechanism within the machine primarily utilizes the gaps between insert plates and two sets of conveyor belts to fold sheets. Each folded insert plate and conveyor belt must be lower than the insert plate and conveyor belt of the previous layer to receive the folded sheet. Consequently, the overall layout of the second folding mechanism is complex, directly increasing the overall size of the machine and resulting in low production efficiency. Within a single workspace, only one sheet can be folded. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a bed sheet patch punching, folding and packaging all-in-one machine in view of the deficiencies of the above-mentioned prior art.

[0008] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a bed sheet patch punching, folding and packaging all-in-one machine, comprising a frame and a rewinding mechanism, a patch mechanism, a punching mechanism, a vertical folding mechanism and a transverse folding mechanism sequentially arranged on the frame along the material transport direction, characterized in that the transverse folding mechanism comprises a first conveyor belt and several groups of first pins perpendicular to the transport direction of the first conveyor belt, the end of the first pin is linked to a first driving mechanism, and the first pin can slide back and forth along the transport direction of the first conveyor belt under the action of the first driving mechanism, and can also be lifted and lowered back and forth along the transport direction perpendicular to the first conveyor belt, and can move away from and approach the first conveyor belt.

[0009] The above-described technical solution solves the problem of uneven folding of materials such as bed sheets in the prior art. The material does not undergo significant positional shifting during the folding process, resulting in a flatter folded material. Furthermore, the device as a whole possesses multiple functions, including patching, punching, and folding. Specifically, the device utilizes several sets of first latches, driven by a first drive mechanism, to achieve folding of the material. During the folding process, one set of first latches initially presses against a portion of the material, while another set of first latches, through their own lifting and lateral displacement, folds the material. During this process, the material does not undergo significant positional shifting due to the first latches. As a result, the folded material is flatter and folds more effectively, thus solving the problem of uneven folding in the prior art. Furthermore, the several sets of first latches are consistently located above the first conveyor belt, allowing the folded material to be positioned solely on the first conveyor belt. Consequently, the folding device provided by the present technical solution has a more streamlined overall structure and occupies a smaller footprint.

[0010] The above-mentioned bed sheet patch punching, folding and packaging integrated machine can be further configured as: the first driving mechanism includes a first slider relatively fixedly connected to the end of the first pin, the first slider is slidably connected to the first slide rail, the first slide rail is arranged perpendicular to the transport direction of the first conveyor belt, the first slide rail is relatively fixedly connected to the second slider, the second slider is slidably connected to the second slide rail, the second slide rail, the first slide rail and the first conveyor belt are distributed perpendicular to each other, the second slide rail is relatively fixedly connected to the third slider, the third slider is slidably connected to the third slide rail, and the third slide rail is arranged parallel to the transport direction of the first conveyor belt.

[0011] By adopting the above technical solution, the first pin can be moved arbitrarily in space, so that part of the first pin can penetrate into the bottom of the bed sheet, part of the first pin can be pressed on top of the bed sheet, the first pin can drive the bed sheet to fold, and after folding, the first pin can exit the bed sheet and other materials.

[0012] The above-mentioned bed sheet patch punching, folding and packaging integrated machine can be further configured as follows: several groups of first pushing mechanisms are arranged at intervals along the transport direction of the first conveyor belt under the first conveyor belt, and the first pushing mechanism includes a top plate and several groups of pushing plates fixedly installed on the top plate and arranged at intervals, and the top plate is linked to a first cylinder.

[0013] By adopting the above technical solution, a first pushing mechanism is provided to lift materials such as bed sheets, thereby leaving a gap between the bed sheets and the first conveyor belt, so that part of the first inserting plate can be inserted under the bed sheets.

[0014] The above-mentioned bed sheet patch punching, folding and packaging integrated machine can be further configured as follows: the first pushing mechanism also includes a mounting plate, the first cylinder is located at the end away from the top plate and is fixedly connected to the mounting plate, the mounting plate is detachably connected to a transverse position adjustment rod, and the transverse position adjustment rod is detachably connected to a longitudinal position adjustment rod.

[0015] By adopting the above technical solution, the position of the mounting plate can be adjusted according to actual conditions, that is, the mounting position of the pusher plate can be adjusted, so that the pusher plate can lift the material more accurately.

[0016] The above-mentioned bed sheet patch punching, folding and packaging integrated machine can be further configured as follows: the frame is also provided with at least one group of second conveyor belts distributed below the first conveyor belt, and above the second conveyor belt are provided with several groups of second pins perpendicular to the conveying direction of the second conveyor belt, and the ends of the second pins are linked to a second driving mechanism. Under the action of the second driving mechanism, the second pins can slide back and forth along the conveying direction of the first conveyor belt, and can be lifted and lowered back and forth perpendicular to the conveying direction of the first conveyor belt, and can move away from and approach the first conveyor belt.

[0017] By adopting the above technical solution, a first conveyor belt, a first latch, a first drive mechanism and other components are provided. This not only completes the folding work, but also does not require the overall position of materials such as bed sheets to change during the folding process. Therefore, at least one set of second conveyor belts is provided below the first conveyor belt. Each conveyor belt can complete the folding work of a set of bed sheets and other materials, without affecting each other and without interfering with each other. Within the same width position range, this technical solution can realize the folding work of two sets of bed sheets and other materials at the same time. Compared with the existing technology, the production efficiency is greatly improved, and the overall structural complexity is not increased. Among them, the second conveyor belt, the second latch, the second drive mechanism and other components are respectively the same as the first conveyor belt, the first latch, and the first drive mechanism, so the overall equipment has good interchangeability.

[0018] The above-mentioned bed sheet patch punching, folding and packaging integrated machine can be further configured as follows: a plurality of second pushing mechanisms are provided below the second conveyor belt and are arranged at intervals along the conveying direction of the second conveyor belt.

[0019] By adopting the above technical solution, a second pushing mechanism is set up to lift materials such as bed sheets, so as to leave a gap between the bed sheets and other materials and the second conveyor belt, so that part of the first insert plate can extend under the bed sheets and other materials; among them, the second pushing mechanism can adopt the same structure as the first pushing mechanism to further improve the overall interchangeability of the equipment.

[0020] The above-mentioned bed sheet patch punching, folding and packaging integrated machine can be further configured as follows: one end of the second conveyor belt is connected to a lower discharge conveyor belt, an upper discharge conveyor belt is provided between the first conveyor belt and the lower discharge conveyor belt, the upper discharge conveyor belt is linked to a fourth slider, the fourth slider is slidably connected to a fourth slide rail, the upper discharge conveyor belt is also linked to a second cylinder, and the upper discharge conveyor belt moves back and forth between the first conveyor belt and the lower discharge conveyor belt under the drive of the second cylinder.

[0021] With the above technical solution, the lower discharge conveyor belt is used to receive and transport folded sheets and other materials; the upper discharge conveyor belt is used to transport folded sheets and other materials on the first conveyor belt to the lower discharge conveyor belt.

[0022] The above-mentioned bed sheet patch punching, folding and packaging integrated machine can be further configured as follows: a pressing mechanism is provided on the lower discharge conveyor belt, and the pressing mechanism includes a pressing plate and a third cylinder linked to the pressing plate.

[0023] By adopting the above technical solution, a material pressing mechanism is provided to flatten the folded material, thereby further improving the flatness of the folded material.

[0024] The above-mentioned bed sheet patch punching, folding and packaging integrated machine can be further configured as follows: the other end of the second conveyor belt is connected to the lower feed conveyor belt, the end of the first conveyor belt located away from the upper discharging conveyor belt is connected to the upper feed conveyor belt, and the upper feed conveyor belt is located at the end away from the first conveyor belt and is inclined toward the lower feed conveyor belt; a pressing and cutting component is provided between the vertical folding mechanism and the horizontal folding mechanism, and a swinging conveyor belt is provided between the pressing and cutting component and the horizontal folding mechanism, one end of the swinging conveyor belt is hinged to the frame, the swinging conveyor belt is hinged to a fourth cylinder, and the fourth cylinder is located at the end away from the swinging conveyor belt and is installed on the frame.

[0025] By adopting the above-mentioned technical solution, the pressing and cutting assembly flattens and cuts the sheets and other materials after the preliminary folding, and the swinging conveyor belt swings up and down under the drive of the fourth cylinder, transporting sheets and other materials toward the upper feed conveyor belt and the lower feed conveyor belt respectively; therefore, by setting the swinging conveyor belt and the fourth cylinder, the vertical folding mechanism and the horizontal folding mechanism having the first conveyor belt and the second conveyor belt are effectively linked to achieve efficient processing.

[0026] The above-mentioned bed sheet patch punching, folding and packaging integrated machine can be further configured as follows: a triangular folding mechanism is provided between the punching mechanism and the vertical folding mechanism.

[0027] By adopting the above technical solution and adding a triangular folding mechanism, materials such as bed sheets can be folded in half before the vertical folding mechanism. This can reduce the size of bed sheets and other materials after processing, making it easier to fold and transport them later. It also further improves the adaptability of the entire machine and can be used to process larger materials such as bed sheets.

DETAILED DESCRIPTION

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0038] like Figures 1 to 7 The illustrated machine for punching, folding, and packaging sheets includes a frame and, arranged sequentially along the material transport direction, an unwinding mechanism 1, a patching mechanism 2, a punching mechanism 3, a triangular folding mechanism 4, a vertical folding mechanism 5, and a horizontal folding mechanism 6. Compared to existing sheet punching and patching machines, the triangular folding mechanism 4 is added to fold the sheet in half before the vertical folding mechanism 5. This reduces the finished sheet size, facilitating subsequent folding and transport. This also further improves the adaptability of the machine, allowing it to process larger sheets and other materials.

[0039] The transverse folding mechanism 6 includes a first conveyor belt 61, four sets of first latches 62 extending perpendicularly to the conveying direction of the first conveyor belt 61, a set of second conveyor belts 63 arranged below the first conveyor belt 61, and four sets of second latches 64 extending perpendicularly to the conveying direction of the second conveyor belt 63. The ends of the first latches 62 are linked to a first drive mechanism 65. Under the action of this first drive mechanism 65, the first latches 62 can slide back and forth along the conveying direction of the first conveyor belt 61, can be lifted and lowered perpendicularly to the conveying direction of the first conveyor belt 61, and can move away from and toward the first conveyor belt 61. The ends of the second latches 64 are linked to a second drive mechanism 67. Under the action of this second drive mechanism 67, the second latches 64 can slide back and forth along the conveying direction of the first conveyor belt 61, can be lifted and lowered perpendicularly to the conveying direction of the first conveyor belt 61, and can move away from and toward the first conveyor belt 61. The second drive mechanism 67 has the same structure as the first drive mechanism 65. By utilizing four sets of first latches 62 (and the same applies to second latches 64), driven by a first drive mechanism 65, materials such as bed sheets can be folded. During the folding process, one set of first latches 62 initially presses against a portion of the material, while the other set of first latches 62 folds the material through their own lifting and lateral displacement. During this process, the material as a whole does not undergo significant positional movement due to the first latches 62. As a result, the folded material is more flat and folds more effectively, thus resolving the uneven folding problem encountered in the prior art. Furthermore, since the four sets of first latches 62 are consistently located above the first conveyor belt 61, the folded position of the material can be achieved solely on the first conveyor belt 61. This results in a more streamlined overall structure and a smaller footprint.

[0040] The first driving mechanism 65 includes a first slider 651 fixedly connected to the end of the first latch 62. The first slider 651 is slidably connected to a first slide rail 652, which is arranged perpendicular to the transport direction of the first conveyor belt 61. The first slide rail 652 is fixedly connected to a second slider 653, which is slidably connected to a second slide rail 654. The second slide rail 654, the first slide rail 652, and the first conveyor belt 61 are arranged perpendicular to each other. The second slide rail 654 is fixedly connected to a third slider 655, which is slidably connected to a third slide rail 656, which is arranged parallel to the transport direction of the first conveyor belt 61. The first latch 62 can be freely moved in space, allowing some of the first latch 62 to penetrate the bottom of the bed sheet, some of the first latch 62 to press on the top of the bed sheet, the first latch 62 to drive the bed sheet to fold, and the first latch 62 to withdraw from the bed sheet after folding.

[0041] Below the first conveyor belt 61, two sets of first pusher mechanisms 66 are arranged at intervals along the conveyor belt 61's direction of transport. These first pusher mechanisms 66 include a top plate 661 and four sets of pusher plates 662 fixedly mounted on the top plate 661 and spaced apart. The top plate 661 is coupled to a first cylinder. The first pusher mechanism 66 also includes a mounting plate 663, which is located at an end away from the top plate 661 and fixedly connected to the mounting plate 663. The mounting plate 663 is detachably connected to a transverse position adjustment rod 664, which is detachably connected to a longitudinal position adjustment rod 665. The first pusher mechanisms 66 are configured to lift materials such as bed sheets, creating a gap between the sheets and the first conveyor belt 61 to allow a portion of the first insert plate to extend beneath the sheets. By providing the transverse and longitudinal position adjustment rods 664 and 665, the position of the mounting plate 663, and therefore the installation position of the pusher plates 662, can be adjusted according to actual conditions, enabling the pusher plates 662 to more accurately lift the materials.

[0042] Below the second conveyor belt 63, two sets of second pushing mechanisms 68 are arranged at intervals along the conveying direction of the second conveyor belt 63. The second pushing mechanisms 68 are provided to lift materials such as bed sheets, creating a gap between the materials and the second conveyor belt 63, allowing a portion of the first insert plate to extend beneath the materials. The second pushing mechanisms 68 share the same structure as the first pushing mechanisms 66, further enhancing the interchangeability of the entire equipment.

[0043] One end of the second conveyor belt 63 is connected to the lower discharge conveyor belt 12. An upper discharge conveyor belt 13 is provided between the first conveyor belt 61 and the lower discharge conveyor belt 12. The upper discharge conveyor belt 13 is linked to a fourth slider 15, which is slidably connected to a fourth slide rail 14. The upper discharge conveyor belt 13 is also linked to a second cylinder 16. Driven by the second cylinder 16, the upper discharge conveyor belt 13 reciprocates between the first conveyor belt 61 and the lower discharge conveyor belt 12. The lower discharge conveyor belt 12 is used to receive and transport folded bed sheets and other materials; the upper discharge conveyor belt 13 is used to transport folded bed sheets and other materials from the first conveyor belt 61 to the lower discharge conveyor belt 12.

[0044] A pressing mechanism 17 is provided on the lower discharge conveyor belt 12. The pressing mechanism 17 includes a pressing plate 171 and a third cylinder 172 linked to the pressing plate 171. The pressing mechanism 17 is provided to flatten the folded material to further improve the flatness of the folded material.

[0045] The other end of the second conveyor belt 63 is connected to the lower feed conveyor belt 7, and the end of the first conveyor belt 61 away from the upper discharge conveyor belt 13 is connected to the upper feed conveyor belt 8, and the upper feed conveyor belt 8 is located at the end away from the first conveyor belt 61 and is inclined toward the lower feed conveyor belt 7; a pressing and cutting component 9 is provided between the vertical folding mechanism 5 and the horizontal folding mechanism 6, and a swinging conveyor belt 10 is provided between the pressing and cutting component 9 and the horizontal folding mechanism 6, one end of the swinging conveyor belt 10 is hinged to the frame, and the swinging conveyor belt 10 is hinged to the fourth cylinder 11, and the fourth cylinder 11 is located at the end away from the swinging conveyor belt 10 and is installed on the frame. The pressing and cutting component 9 flattens and cuts the sheets and other materials after preliminary folding, and the swinging conveyor belt 10 swings up and down driven by the fourth cylinder 11, transporting sheets and other materials toward the upper feed conveyor belt 8 and the lower feed conveyor belt 7 respectively; therefore, by setting the swinging conveyor belt 10 and the fourth cylinder 11, the vertical folding mechanism 5 and the horizontal folding mechanism 6 having the first conveyor belt 61 and the second conveyor belt 63 are effectively linked to achieve efficient processing.

[0046] This specific embodiment has the following advantages:

[0047] ① The first latch 62 and the first conveyor belt 61, the second latch 64 and the second conveyor belt 63 are set as the main folding tools. The bed sheets and other materials will not move significantly as a whole during the folding process, which solves the problem of uneven folding of bed sheets and other materials in the existing technology. The folded bed sheets and other materials are flatter, and the whole device has multiple functions of patching, punching and folding.

[0048] ② The arrangement of the first conveyor belt 61, first latch 62, and first drive mechanism 65 not only allows for the folding process, but also eliminates the need for the entire sheet material to change position during the folding process. Therefore, a second conveyor belt 63 is positioned below the first conveyor belt 61. Each conveyor belt can fold a separate set of sheets, without interfering with each other. Within the same width, this solution allows for the simultaneous folding of two sets of sheets, significantly improving production efficiency compared to existing technologies without increasing overall structural complexity.

[0049] ③ The overall equipment has good interchangeability. For example, the second conveyor belt 63, the second latch 64, the second drive mechanism 67 and other components are respectively consistent with the first conveyor belt 61, the first latch 62, and the first drive mechanism 65 in structure.

[0050] ④ A triangular folding mechanism 4 is added to fold the sheets and other materials in half before the vertical folding mechanism 5. This can reduce the size of the sheets and other materials after processing, making it easier to fold and transport them. It also further improves the adaptability of the entire machine and can be used to process larger sheets and other materials.

[0051] The working principle of this specific embodiment is as follows: the unwinding mechanism 1 delivers the bed sheet raw materials in sequence, and the raw materials are passed through the patch mechanism 2 and the punching mechanism 3 for patching and punching (the patch mechanism 2 and the punching mechanism 3 are existing technologies, so they are not elaborated in detail in this application). Then, they are preliminarily folded in half by the triangular folding mechanism 4, and further folded by the vertical folding mechanism 5. The folded bed sheet is cut by the pressing and cutting mechanism (the cutting length is selected according to the actual situation and is not a fixed value), and then the preliminarily folded bed sheet is delivered to the upper feed conveyor belt 8 and the lower feed conveyor belt 7 in sequence via the swing conveyor belt 10. The bed sheet folding work is carried out separately at the first conveyor belt 61 and the second conveyor belt 63, without interfering with each other, and the production efficiency is high.

[0052] In order to understand the folding process of the bed sheet at the transverse mechanism more clearly, as shown in the attached Figure 5 As shown, taking the first conveyor belt 61 as an example for specific description, the folding steps specifically include the following:

[0053] 1) As attached Figure 3 The first latch 62 shown includes four groups of first latches 62a, first latches 62, first latches 62c, and first latches 62d;

[0054] 2) The first latch 62b and the first latch 62c respectively press the material;

[0055] 3) The first latch 62a and the first latch 62d are respectively inserted under the material (between the material and the first conveyor belt 612);

[0056] 4) The first latch 62a lifts the material upward and moves it toward the first latch 62b until the material is folded; similarly, the first latch 62d lifts the material upward and moves it toward the first latch 62c until the material is folded;

[0057] 5) The first latch 62b lifts the material upward and moves it toward the first latch 62a until the material is folded;

[0058] 6) The first latch 62c lifts the material upward and moves it toward the first latch 62d until the material is folded.

[0059] The material after folding according to the above steps is in a folded state, and the folding steps can be changed according to actual conditions. It only needs to change the movement order between the first latch 62a, the first latch 62b, the first latch 62c, and the first latch 62d, etc., and you can also choose which pin to press down and fold respectively. These can be selectively changed on the equipment provided in this specific embodiment without creative labor. Therefore, the above folding steps are only for better facilitating those skilled in the art to understand this specific embodiment more clearly, and are not a limitation of this application.
