Description

Technical Field

[0001] This utility model relates to the field of tissue paper folding equipment technology, and in particular to a fully automatic bottom-drawing soft tissue paper folding machine that can handle both thick and thin tissues. Background Technology

[0002] Cotton soft towels, made from 100% pure natural cotton using advanced spunlace nonwoven fabric technology and high-pressure steam sterilization, are soft, delicate, highly absorbent, and lint-free. They are gradually becoming an environmentally friendly alternative to paper towels, cotton pads, and face towels, and their market demand is growing. Cotton soft towels are typically produced using cotton soft towel folding machines.

[0003] However, the existing equipment has the following shortcomings: During use, when the second support descends and the first support replaces the second support to support the cotton towel, because the cotton towel is folded, the first support frame easily inserts into the middle of the folded cotton towel ">", causing one end of the cotton towel to dangle below the first support frame. This affects the second support's ability to exchange the cotton towel above the first support frame. Therefore, we proposed a fully automatic bottom-drawing folding machine for both thick and thin soft towels to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to solve the shortcomings of the existing technology where the second support and the first support cause wrinkles or shifts when exchanging cotton towels, which affects the exchange of cotton towels by the second support. The invention proposes a fully automatic bottom-drawing cotton towel folding machine that can handle both thick and thin towels.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a fully automatic bottom-drawing cotton towel folding machine (for both thick and thin towels), comprising a base, a transmitter, a first support, a roller, a power unit, a second support, and an air blowing device. The transmitter is installed on the upper surface of the base, the first support is fixedly connected to the upper surface of the base and is installed above the transmitter, the roller is fixedly connected between the power units, the power unit is fixedly connected to the upper surface of the base, the second support is installed on the upper surface of the base, and the air blowing device is installed on the upper surface of the second support. The air blowing device includes a connecting plate and a support column. The support column is fixedly connected to the upper surface of the second support and fixes the height of the connecting plate to ensure that the distance between the air outlet and the surface of the cotton towel is constant, so that the airflow is uniform. The connecting plate is fixedly connected to the upper surface of the support column, and a pipe is fixedly connected to one end of the connecting plate near the second support.

[0006] Furthermore, a connector is fixedly connected to the end of the pipe away from the connecting plate. By setting the connecting plate, the gas that initially enters the equipment can be diverted, reducing the difficulty of accurately diverting the gas during equipment use and preventing uneven gas output.

[0007] Furthermore, an air outlet is fixedly connected to the end of the connector away from the pipe, and the air outlet end of the air outlet is installed above the second bracket. The connector enhances the sealing between the pipe and the air outlet and reduces air pressure loss.

[0008] Furthermore, an air inlet is fixedly connected to the end of the connecting plate away from the pipe, and a connecting pipe is fixedly connected to the end of the air inlet away from the connecting plate.

[0009] Furthermore, an auxiliary component is fixedly installed inside the air intake head. The auxiliary component includes an air intake hole and a baffle. The air intake hole is opened inside the air intake head, and the baffle is installed inside the air intake head. A rubber ring is fixedly connected inside the upper end of the air intake head, and the baffle is slidably connected inside the rubber ring. By setting the rubber ring, the rubber ring enhances the sealing between the baffle and the air intake head and reduces air leakage.

[0010] Furthermore, an installation head is fixedly connected to the upper end of the baffle, and a cylinder is fixedly connected to the upper end of the installation head.

[0011] Furthermore, a support plate is fixedly connected to the side of the cylinder, and the support plate is fixedly connected to the upper surface of the air intake head.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by incorporating an air-blowing device, the cotton towel at the lower end of the first support is effectively and tightly fitted to the first support. This facilitates the replacement of the cotton towel at the upper end of the first support by the second support. It also reduces the problems encountered in existing systems where, during the exchange of support between the second support and the first support, the cotton towel is folded, and the first support frame can easily insert into the middle of the folded cotton towel ">", causing one end of the cotton towel to dangle below the first support, resulting in wrinkles or misalignment. This hinders the second support from replacing the cotton towel at the upper end of the first support frame. This air-blowing device, through its air outlet, tightly fits the dangling cotton towel to the bottom of the first support, facilitating the exchange of support between the second support and the upper end of the first support frame, thus improving the practicality of the equipment.

[0013] In this invention, by setting auxiliary components, the device adjusts the gas inside the air inlet head, and then starts the cylinder extension end to drive the mounting head and baffle to move up and down. The baffle slides inside the rubber ring to adjust the opening and closing degree of the air inlet, thereby controlling the air flow rate entering the blowing device. Attached Figure Description

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] Please see Figures 1-5 This utility model provides a technical solution: a fully automatic bottom-drawing cotton towel folding machine for both thick and thin towels, including a base 1, a transmitter 2, a first support 3, a roller 4, a power unit 5, a second support 6, and an air blowing device 7. The transmitter 2 is installed on the upper surface of the base 1, the first support 3 is fixedly connected to the upper surface of the base 1 and is installed above the transmitter 2, the roller 4 is fixedly connected between the power units 5 and the power units 5 are fixedly connected to the upper surface of the base 1, and the second support 6 is installed on the upper surface of the base 1.

[0019] The base 1 is welded from heavy-duty steel, with strong load-bearing capacity, ensuring stable operation without shaking; the conveyor 2 is a belt conveyor structure with an anti-slip surface, which can smoothly transport cotton towels; the first support 3 and the second support 6 are both made of high-strength alloy material, with good rigidity and not easy to deform, and can accurately complete the support replacement action; the roller 4 is a smooth metal roller, and the rolling pressure can be adjusted according to the thickness of the cotton towel; the power unit 5 is a servo motor with controllable speed, which can provide stable power to the roller 4.

[0020] The following section will describe in detail the specific settings and functions of its air blowing device 7 and auxiliary components 8.

[0021] In this embodiment: the air blowing device 7 is installed on the upper surface of the second support 6. The air blowing device 7 includes a connecting plate 71 and a support column 73. The support column 73 is fixedly connected to the upper surface of the second support 6. The support column 73 fixes the height of the connecting plate 71 to ensure that the distance between the air outlet 75 and the surface of the cotton towel is constant, so that the airflow is uniform. The connecting plate 71 is fixedly connected to the upper surface of the support column 73. The connecting plate 71 is a hollow metal plate with a reasonable airflow channel design, which can realize uniform gas distribution. A pipe 72 is fixedly connected to one end of the connecting plate 71 near the second support 6.

[0022] Specifically, a connector 74 is fixedly connected to the end of pipe 72 away from the connecting plate 71.

[0023] In this embodiment, by setting up the connecting plate 71, the gas initially entering the equipment can be diverted, reducing the difficulty of accurately diverting the gas during use and preventing uneven gas output.

[0024] Specifically, an air outlet 75 is fixedly connected to the end of the connector 74 away from the pipe 72. The air outlet 75 is a flat nozzle that can generate directional airflow. The air outlet end of the air outlet 75 is installed above the second bracket 6. The connector 74 enhances the sealing between the pipe 72 and the air outlet 75 and reduces air pressure loss.

[0025] Specifically, an air inlet 76 is fixedly connected to the end of the connecting plate 71 away from the pipe 72, and a connecting pipe 77 is fixedly connected to the end of the air inlet 76 away from the connecting plate 71.

[0026] In this embodiment: An auxiliary component 8 is fixedly installed inside the air intake head 76. The auxiliary component 8 includes an air intake hole 81 and a baffle 82. The air intake hole 81 is opened inside the air intake head 76, and the baffle 82 is installed inside the air intake head 76. A rubber ring 83 is fixedly connected inside the upper end of the air intake head 76, and the baffle 82 is slidably connected inside the rubber ring 83.

[0027] In this embodiment: by setting a rubber ring 83, the rubber ring 83 enhances the sealing between the baffle 82 and the air inlet head 76, reducing air leakage.

[0028] Specifically, a mounting head 84 is fixedly connected to the upper end of the baffle 82, and a cylinder 85 is fixedly connected to the upper end of the mounting head 84.

[0029] Specifically, a support plate 86 is fixedly connected to the side of the cylinder 85, and the support plate 86 is fixedly connected to the upper surface of the air intake head 76.

[0030] For thin cotton towels, the airflow pressure can be reduced to prevent the towels from tearing due to excessive airflow. For thick cotton towels, the airflow pressure is increased to ensure sufficient thrust to complete the folding, thus meeting the need for one machine to adapt to products of different thicknesses.

[0031] Working Principle: When using the equipment, the user guides the cotton towel material into the roller 4 via the roller at the top of the power unit 5. The power unit 5 is then activated, driving the roller 4 to rotate and crush the cotton towel material at adjustable pressure. The cotton towel then enters the folding station at the bottom of the roller 4 for folding. The first support 3 and the second support 6 support the folded material. When a certain number of cotton towels are placed on the upper part of the second support 6, it moves downwards rapidly. The first support 3 then inserts horizontally to replace the second support 6 in supporting the cotton towels. The second support 6 then moves downwards, placing the cotton towels on the surface of the conveyor 2. After moving the folded cotton towels, the second support 6 rises again to support the cotton towels on the upper part of the first support 3. The first support 3 then retracts. The second support 6 and the second support 6 then repeat the folding process for fully automatic folding of the cotton towels. When the second support 6 is raised and lowered to replace the cotton towels supported on the upper part of the first support 3, compressed air is introduced into the connecting pipe 77 through the air inlet 76. The air enters the connecting plate 71, is diverted to the pipe 72, and finally sprays out from the air outlet 75. The air outlet 75 is evenly distributed above the second support 6. The sprayed air can gently push the edge of the cotton towel. By setting the air blowing device 7, the cotton towel at the lower end of the first support 3 is effectively and tightly attached to the first support 3, which facilitates the replacement of the cotton towel at the upper end of the first support 3 by the second support 6. This reduces the problem that in the existing use, when the second support 6 descends and the first support 3 replaces the second support 6 to support the cotton towel, the first support frame is prone to inserting into the middle of the folded cotton towel ">" during the exchange support process. This causes one end of the cotton towel to be suspended at the lower end of the first support 3, resulting in wrinkles or displacement, which affects the second support to exchange the cotton towel at the upper end of the first support frame. This air blowing device 7, through the air outlet 75, tightly attaches the suspended cotton towel to the lower part of the first support 3, which facilitates the exchange support of the cotton towel at the upper end of the first support 3 by the second support 6, thus improving the practicality of the equipment.

[0032] The equipment adjusts the gas inside the air inlet 76, and then starts the cylinder 85 extension end to drive the mounting head 84 and baffle 82 to move up and down. The baffle 82 slides in the rubber ring 83 to adjust the opening and closing degree of the air inlet 81, thereby controlling the air flow rate entering the air blowing device 7.

[0033] The auxiliary component 8 works in conjunction with the air blowing device 7 to ensure that the airflow response time is ≤0.5 seconds. It can be adjusted in real time according to the speed of the conveyor 2 (10-30m / min), reducing folding lag in the high-speed conveying of cotton towels. For cotton towels of uneven thickness, the folding deviation caused by the difference in raw materials can be compensated by adjusting the local airflow intensity. The folding accuracy is high and the adaptability is strong. The combination of the directional airflow of the air blowing device 7 and the flow control of the auxiliary component 8 ensures that the folding qualification rate of both thin and thick cotton towels reaches more than 99%, reducing the defect rate by 50% compared with traditional mechanical folding. The entire process requires no manual intervention, and the folding speed is adjusted synchronously with the conveyor 2. The daily production capacity can reach 100,000 to 300,000 pieces, meeting the needs of large-scale production.

[0034] The above description discloses only one or more preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of the present utility model still fall within the scope of the present utility model.
