Description

Technical Field

[0001] This utility model relates to the technical field of hand towel equipment, specifically a hand towel folding and feeding device. Background Technology

[0002] Previously, the feeding of hand towel folding equipment relied on manual loading. Because hand towels are relatively thin, manual operation was not only inconvenient but also labor-intensive and inefficient due to prolonged work. Therefore, our company designed a device that uses a blower to drive suction cups to draw air, combined with a push rod to move the hand towels for loading. This improved the loading effect and increased efficiency. After using this device for a period of time, we found that there is still room for optimization. When the solenoid valve on the blower stops the suction cups, allowing the hand towels to fall onto the loading conveyor, they naturally sink to the conveyor under gravity. The sinking speed is slow. Increasing this speed would further improve the efficiency of the entire hand towel folding process and increase production progress. Therefore, we propose a new type of hand towel folding and loading equipment. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a hand towel folding and feeding device, which aims to further improve the feeding efficiency of hand towels based on existing technologies.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A hand towel folding and feeding device includes a folding device and an installation plate disposed on one side of the folding device. A suction cup is installed at the bottom of the installation plate, and a guide post is fixedly installed at the top of the installation plate. A buffer pressure plate and a slide are slidably sleeved on the guide post. A buffer spring sleeved on the guide post is provided between the buffer pressure plate and the installation plate. The slide is slidably connected to a horizontally fixed cross rail on the folding device.

[0006] A lifting push rod that is connected to the buffer pressure plate is fixedly connected to the slide. A support frame located above the lifting push rod is also fixed on the slide. A blower and a Venturi jet are fixed on the support frame. The blower is connected to the air inlet of the Venturi jet. The suction inlet of the Venturi jet is connected to the suction cup through a connecting pipe. A sealing plug corresponding to the nozzle of the Venturi jet is fixed above the folding conveyor on the folding device.

[0007] Preferably, it also includes a lead screw stepper motor that is connected to the slide table drive above the horizontal rail.

[0008] Preferably, the Venturi jet is arranged in parallel with the lead screw stepper motor and the folding conveyor.

[0009] Preferably, the sealing plug is a conical rubber plug coaxially arranged with the Venturi jet.

[0010] Preferably, the sealing plug is mounted on the folding device via a bracket.

[0011] Preferably, the connecting tube includes a connecting hose connected to the suction port of the venturi jet injector, a distributor connected to the lower end of the connecting hose, and a distributor tube between the distributor and the suction cup.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention utilizes a blower to generate negative pressure to adsorb hand towels using a Venturi jet injector. When the injector moves to the right for loading, the nozzle of the Venturi jet injector is blocked by a sealing plug on the right side. The airflow generated by the blower is redirected to the intake port of the Venturi jet injector, allowing air to be blown downwards from the suction cup. This enables the hand towels adsorbed by the suction cup to fall smoothly and quickly onto the folding conveyor below. This design not only simplifies the structure and makes implementation more convenient, but also further improves the efficiency of hand towel loading and enhances practicality compared to existing technologies.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-2As shown, this utility model provides a technical solution: a hand towel folding and feeding device, including a folding device 1 and an installation plate 2 disposed on one side of the folding device 1, and a lead screw stepper motor 16 connected to the slide table 6 above the horizontal rail 8. A suction cup 3 is installed at the bottom of the installation plate 2, and a guide post 4 is fixedly installed at the top of the installation plate 2. A buffer pressure plate 5 and a slide table 6 are slidably sleeved on the guide post 4. A buffer spring 7 sleeved on the guide post 4 is provided between the buffer pressure plate 5 and the installation plate 2. The slide table 6 is slidably connected to the horizontal rail 8 that is horizontally fixed on the folding device 1.

[0019] A lifting push rod 9, which is connected to the buffer plate 5, is fixedly connected to the slide table 6. A support frame 10 located above the lifting push rod 9 is also fixed on the slide table 6. A blower 11 and a Venturi jet 12 are fixed on the support frame 10. The Venturi jet 12 is arranged in parallel with the lead screw stepper motor 16 and the folding conveyor 14. The blower 11 is connected to the air inlet of the Venturi jet 12. The suction inlet of the Venturi jet 12 is connected to the suction cup 3 through the connecting pipe 13.

[0020] The connecting pipe 13 includes a connecting hose 131 connected to the suction port of the Venturi jet injector 12, a distributor 132 connected to the lower end of the connecting hose 131, and a distributor pipe 133 between the distributor 132 and the suction cup 3. A sealing plug 15 corresponding to the nozzle of the Venturi jet injector 12 is fixed above the folding conveyor 14 on the folding device 1. The sealing plug 15 is a conical rubber plug coaxially arranged with the Venturi jet injector 12. The sealing plug 15 is installed on the folding device 1 through the bracket 17.

[0021] Working principle:

[0022] Blower 11 blows air onto Venturi jet 12, creating negative pressure on suction cup 3. Lifting push rod 9 moves buffer plate 5, mounting plate 2, and suction cup 3 up and down. Suction cup 3 descends to adsorb hand towel 18 and lifts it up. Screw stepper motor 16 moves slide table 6 to the right onto folding conveyor 14. The nozzle of Venturi jet 12 is blocked by sealing plug 15 on the right side. The airflow generated by blower 11 is instead output downward from the suction port of Venturi jet 12 and blows air downward from suction cup 3, allowing the hand towel 18 adsorbed by suction cup 3 to fall smoothly and quickly onto the folding conveyor 14 below, improving the feeding efficiency of hand towel 18.
