Description

Technical Field

[0001] This utility model relates to the field of cotton filling machine technology, specifically to a cotton filling machine that can recycle cotton wadding. Background Technology

[0002] A cotton filling machine, also known as a stuffing machine, is a machine that fills plush toys, sofa cushions, pillows, or pillow covers with PP cotton or other filling materials. It is generally used in industries such as plush toys, home textiles, furniture, and clothing. Compared with manual filling, the advantages of cotton filling machine are high work efficiency, reduced labor costs, and better product quality. Products filled by cotton filling machine are full and uniform, and have a better feel than those filled by hand.

[0003] Existing cotton filling machines typically require pre-setting the filling weight in grams before filling, and then the machine fills the outer jacket with the corresponding amount of cotton according to the set value. However, during the filling process, some cotton fibers may remain in the filling pipes or fall outside the jacket, so the final filling weight often does not meet the requirements. Therefore, the existing process requires transferring the filled item to a manual station for weighing and manually supplementing the missing weight, which is time-consuming, labor-intensive, inconvenient, and affects production efficiency. Furthermore, the cotton fibers that fall outside the jacket during the filling process cannot be recovered, resulting in waste of cotton materials. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a cotton filling machine that can recycle cotton wadding. It can measure the filling weight in real time during filling and recycle the fallen cotton wadding, making it more convenient to use.

[0005] This utility model is achieved through the following technical solution: a cotton filling machine for recyclable cotton wadding, comprising a filling machine body, a cotton wadding bin and a filling fan for expelling cotton wadding, the inlet of the filling fan being connected to the cotton wadding bin, a workbench, a buffer box fixedly mounted on the workbench, the buffer box having an inlet and an outlet, the outlet of the filling fan being connected to the inlet of the buffer box via a first conveying pipe, the outlet of the buffer box being connected to a filling pipe, and a weighing scale also being mounted on the workbench, the filling pipe being positioned opposite to the weighing scale.

[0006] This solution uses a buffer box to cushion the cotton wadding expelled by the filling blower, reducing the flow rate of the wadding and preventing it from scattering inside the outer jacket due to excessive speed, thus avoiding uneven filling. It also effectively reduces the amount of wadding that escapes outside the jacket. By installing a weighing scale on the workbench, the outer jacket can be placed directly on the scale for filling, with weighing and filling occurring simultaneously. This allows personnel to easily monitor the filling weight in real time and stop filling when the required weight is reached, facilitating weight control, improving ease of use, and increasing production efficiency.

[0007] As an optimization, a cotton-drawing fan is also included. The inlet of the cotton-drawing fan is connected to a cotton-drawing pipe, and the outlet of the cotton-drawing fan is connected to the cotton wadding bin through a second conveying pipe. This optimized solution uses the cotton-drawing fan to provide airflow, and the cotton wadding that falls outside the outer cover can be sucked back into the cotton wadding bin through the cotton-drawing pipe, avoiding material waste.

[0008] As an optimization, a collection hopper is fixedly installed at the bottom of the workbench. The upper port of the collection hopper is connected to the top surface of the workbench, and the lower port of the collection hopper is connected to the cotton extraction pipe. The weighing scale is located above the collection hopper. This optimized solution, by placing the weighing scale above the collection hopper, allows cotton lint that falls during filling to fall directly into the collection hopper and be extracted by the cotton extraction pipe, making cotton lint recovery more convenient and timely.

[0009] As an optimization, the cotton extraction pipe includes a tee fitting, a first branch pipe, a second branch pipe, and a third branch pipe. One end of each of the first, second, and third branch pipes is connected to one of the three ports of the tee fitting. The other end of the first branch pipe is connected to the inlet of the cotton extraction fan, the other end of the second branch pipe is connected to the lower port of the collection hopper, and the third branch pipe is open to the outside air. This optimized cotton extraction pipe, through the third branch pipe, extracts and collects cotton fibers floating in the air and those that have fallen to the ground, improving the cotton fiber recovery rate.

[0010] As an optimization, the third branch pipe is a corrugated flexible hose. This optimized design uses a flexible hose for the third branch pipe, making it easier for personnel to adjust different suction positions and angles.

[0011] As an optimization, two support plates are fixed to the upper end of the collection hopper. The weighing scale includes a placement plate and four weighing sensors fixed to the four corners of the bottom of the placement plate. The four weighing sensors are fixed to the two support plates in pairs. In this optimized design, the placement plate is used to place the outer cover, and the weight is detected by the four weighing sensors, resulting in higher accuracy.

[0012] The beneficial effects of this utility model are as follows: by controlling the operation of the weighing scale and the filling fan through the controller, the weighing and filling can be carried out simultaneously, the filling weight can be detected in real time, and the filling can be stopped when the requirement is met, which makes it convenient to control the filling weight, has a higher degree of automation, is more convenient to use, and improves production efficiency.

[0013] During the filling process, a cotton extraction fan is used to collect cotton lint that falls onto the workbench, floats in the air, or falls to the ground, resulting in a higher recycling rate and avoiding material waste. Attached Figure Description

Detailed Implementation

[0020] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0021] like Figures 1-4 As shown, a cotton filling machine for recyclable cotton wadding includes a filling machine body 1, which is provided with a cotton wadding bin 12 and a filling fan 10 for blowing out cotton wadding. The inlet of the filling fan 10 is connected to the cotton wadding bin 12.

[0022] Specifically, in this embodiment, the cotton filling machine body 1 includes a housing 21. A horizontal partition is fixedly connected inside the housing 21, dividing the inner cavity of the housing 21 into a cotton wadding bin 12 and an equipment bin 13 distributed vertically. The cotton wadding bin 12 is used to store cotton wadding, and the equipment bin 13 is used to house equipment. The cotton filling fan 10 is installed inside the equipment bin 13. The input port of the cotton filling fan 10 is connected to the horizontal partition through a first air duct 14, thus communicating with the cotton wadding bin 12. The output port of the cotton filling fan 10 is connected to the outside of the front side wall of the housing 21 through a second air duct 15.

[0023] In this embodiment, the front wall of the housing 21 is provided with an observation window 20 corresponding to the cotton wadding 12 for easy observation of the amount of cotton wadding. The top of the housing 21 has an air inlet 16 communicating with the cotton wadding 12 to facilitate airflow. The left and right side walls of the housing 21 have heat dissipation holes 18 communicating with the equipment compartment 13 for heat dissipation. The rear side wall of the housing 21 has an upper cotton inlet corresponding to the cotton wadding 12 and an inspection port corresponding to the equipment compartment 13. Both the upper cotton inlet and the inspection port are hinged with doors 17. Cotton wadding is added to the cotton wadding 12 through the upper cotton inlet, and the equipment inside the equipment compartment 13 is easily inspected and maintained through the inspection port.

[0024] The cotton wadding 12 is also equipped with a stirring mechanism for stirring the cotton wadding. The stirring mechanism can adopt the stirring device in patent CN216549618U. The stirring mechanism disperses the cotton wadding in the cotton wadding hopper, ensuring the softness of the cotton wadding and preventing the cotton wadding from clumping. This is a conventional technology and will not be elaborated on here.

[0025] The cotton filling machine also includes a workbench 2, which in this embodiment is located on the front side of the main body 1 of the cotton filling machine. A buffer box 3 is fixed on the workbench 2, and the buffer box 3 has a feed inlet and a discharge outlet. The output port of the cotton filling fan 10 is connected to the feed inlet of the buffer box 3 through a first conveying pipe 9, and the discharge outlet of the buffer box 3 is connected to a cotton filling pipe 8. A weighing scale 4 is also provided on the workbench 2, and the cotton filling pipe 8 is arranged opposite to the weighing scale 4.

[0026] The buffer box 3 buffers the cotton wadding expelled by the filling blower 10, reducing the flow rate of the cotton wadding and preventing it from scattering inside the jacket due to excessive flow, thus avoiding uneven filling. It also effectively reduces the amount of cotton wadding that escapes outside the jacket. During filling, the jacket can be placed directly on the weighing scale 4. Since the filling tube is opposite the weighing scale, it is convenient to insert the filling tube 8 directly into the jacket for filling, allowing weighing and filling to occur simultaneously. This allows personnel to easily observe the filling weight in real time and control the filling weight. Filling can be stopped when the required weight is reached, making it more convenient and efficient.

[0027] The cotton filling machine also includes a cotton extraction fan 5, which in this embodiment is located at the bottom of the workbench 2. The input port of the cotton extraction fan 5 is connected to a cotton extraction pipe 6, and the output port of the cotton extraction fan 5 is connected to the cotton wadding hopper 12 through a second conveying pipe 11. A collection hopper 7 is fixedly provided at the bottom of the workbench 2. The upper port of the collection hopper 7 is connected to the top surface of the workbench 2, and the lower port of the collection hopper 7 is connected to the cotton extraction pipe 6.

[0028] Specifically, the cotton extraction pipe 6 includes a tee fitting 64, a first branch pipe 61, a second branch pipe 62, and a third branch pipe 63. One end of the first, second, and third branch pipes is connected to the three ports of the tee fitting 64, respectively. The other end of the first branch pipe 61 is connected to the inlet of the cotton extraction fan 5, the other end of the second branch pipe 62 is connected to the lower port of the collection hopper 7, and the third branch pipe 63 is in communication with the outside air.

[0029] During the filling process, cotton lint that falls onto the workbench 2 enters the collection hopper 7 and is then drawn away and recycled by the cotton extraction fan 5. The third branch pipe 63 can collect and recycle cotton lint floating in the air and that has fallen to the ground, improving the cotton lint recovery rate.

[0030] In this embodiment, the third branch pipe 63 is a corrugated flexible hose. The flexible hose allows personnel to easily adjust different suction positions and angles.

[0031] The weighing scale 4 is located above the collection hopper 7. Cotton fibers that fly out of the outer casing during filling can fall directly into the collection hopper for collection.

[0032] Specifically, two support plates 19 are fixedly connected to the upper end of the collection hopper 7, and the two support plates 19 are parallel and opposite to each other. The weighing scale 4 includes a placement plate 41 and four weighing sensors 42 fixed to the four corners of the bottom of the placement plate 41. The four weighing sensors 42 are paired up and fixed to the two support plates 19 respectively. In this way, two weighing sensors 42 are fixed on each support plate 19, and the items on the placement plate are weighed by four weighing sensors, which has higher accuracy.

[0033] like Figure 1 As shown, the cotton filling machine body 1 of this embodiment is provided with two cotton filling fans 10. The two cotton filling fans 10 are symmetrically distributed in the housing 21. Each cotton filling fan is provided with a workbench, a buffer box, a weighing scale and a cotton extraction fan, so that one cotton filling machine can simultaneously perform cotton filling operations on two outer jackets, thereby improving efficiency.

[0034] The system also includes a controller, with the weighing sensor 42 and the cotton filling fan 10 both connected to the controller via signal connections. This embodiment of the cotton filling machine also includes a control console, in which the controller is installed, and the cotton extraction fan 5 is also connected to the controller via signal connections. The control console is equipped with a control panel and a display screen. The control panel has power buttons for individually controlling the start and stop of the cotton filling fan 10, the cotton extraction fan 5, and the weighing scale 4. The display screen can show the weight in real time. During cotton filling, the weighing sensor 42 transmits the detected weight to the controller for processing. When the set weight is reached, the controller can control the cotton filling fan 10 to stop filling, making the system more automated. The controller's control program can be implemented by those skilled in the art through programming, which will not be elaborated upon here.

[0035] Working principle: The filling weight is set via the control panel. The outer jacket to be filled is placed on the weighing scale's placement plate. The filling tube is inserted into the jacket. The filling fan transports the cotton wadding from the wadding bin to the buffer tank, where it is then filled into the jacket through the filling tube. Cotton wadding that falls onto the worktable during filling is collected in a collection hopper. A third branch pipe collects cotton wadding floating in the air and falling on the ground. The collected cotton wadding is then transported back to the wadding bin by a cotton extraction fan. The weighing sensor on the weighing scale transmits the detected weight to the controller for processing. When the set weight is reached, the controller stops the filling fan.

[0036] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solution of this utility model and are not intended to limit this utility model. This utility model has been described in detail with reference to preferred embodiments. Those skilled in the art should understand that any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model do not depart from the spirit of this utility model and should also fall within the protection scope of the claims of this utility model.
