Description

Technical Field

[0001] This utility model relates to the field of light processing technology, and in particular to a cotton filling machine. Background Technology

[0002] In the existing technology, cotton filling machines usually deliver the filling material through airflow and perform the final filling operation using a detachable filling nozzle. Currently, there are two main types of filling nozzle connection methods: one is threaded connection, and the other is clamping.

[0003] While the mainstream threaded connection method offers reliable connections, it suffers from cumbersome operation, low efficiency, and issues such as thread wear and lint accumulating easily. Conversely, the clamping method, though simple to operate, is prone to air leakage due to uneven clamping, damage to the clamp itself, and insecure fixing. These problems directly impact production efficiency and increase equipment maintenance costs. Utility Model Content

[0004] In view of this, the present invention provides a cotton filling machine to solve the problem that the connection method between the cotton filling machine and the cotton filling nozzle in the prior art is difficult to balance connection efficiency and connection reliability.

[0005] To achieve one, some, or all of the above objectives, or other objectives, this utility model proposes a cotton filling machine, including a machine body, a cotton filling mechanism, and a connecting mechanism. The machine body is provided with a cotton storage chamber, and a cotton filling port connected to the cotton storage chamber is opened on the front side of the machine body. The cotton filling mechanism is used to drive the cotton wadding in the cotton storage chamber to be evenly sprayed out from the cotton filling port. The connecting mechanism includes a connecting seat and at least two hand-adjusting bolts. The connecting seat is fixed on the front side wall of the machine body and covers the cotton filling port. The connecting seat is provided with a slot connected to its side, and the slot is connected to the cotton filling port. The front side wall of the connecting seat is provided with a notch connected to the slot. The two hand-adjusting bolts are vertically screwed onto the front side wall of the connecting seat and are evenly distributed along the circumference of the cotton filling port. The cotton filling nozzle can be inserted into the slot through the notch and connected to the cotton filling port. At this time, turning the hand-adjusting bolts can squeeze the edge of the cotton filling nozzle and lock the cotton filling nozzle at the cotton filling port.

[0006] Preferably, the connecting seat includes a base plate and a U-shaped baffle. The base plate is fixedly laid on the front side wall of the machine body and covers the filling port. The front side wall of the base plate has a receiving groove that connects to its side. The inner wall of the receiving groove has a connecting port that connects to the filling port. The U-shaped baffle is fixedly laid on the front side wall of the base plate and forms a slot with the inner wall of the receiving groove. The inner side of the U-shaped baffle forms a notch.

[0007] Preferably, the filling mechanism includes a drive shaft, a stirring paddle, cotton-dispensing fan blades, an air nozzle, a drive component, and an air tank. The drive shaft is horizontally rotatably disposed within the cotton storage chamber. The stirring paddle is fixed in the middle of the drive shaft. The cotton-dispensing fan blades are disposed at one end of the drive shaft near the filling port. The air nozzle is disposed adjacent to the filling port within the cotton storage chamber. The drive component and the air tank are both disposed within the machine body. The drive component is used to drive the drive shaft to rotate, causing the stirring paddle to continuously agitate the cotton fibers in the cotton storage chamber, preventing the cotton fibers from clumping, and to drive the cotton-dispensing fan blades to push the loosened cotton fibers towards the filling port. The air tank supplies air to the air nozzle, and the high-speed airflow ejected from the air nozzle blows the cotton fibers from the filling port to the filling nozzle.

[0008] Preferably, the end of the cotton-removing fan blade away from the drive shaft is provided with serrations.

[0009] Preferably, the driving component is a motor, which is built into the bottom of the machine body. One end of the transmission shaft extends out of the cotton storage cavity and is coaxially provided with a transmission wheel. The transmission wheel and the motor are driven by a belt.

[0010] Preferably, the cotton filling machine further includes a fan, which is built into the bottom of the machine body. The air inlet of the fan is connected to a cotton inlet pipe extending to the outside of the machine body, and the air outlet of the fan is connected to an air outlet pipe extending upward and connecting to the cotton storage chamber.

[0011] Preferably, the end of the cotton inlet pipe furthest from the blower is connected to a feed hopper.

[0012] Preferably, a lower cotton inlet is provided on the side wall of the cotton storage chamber, the cotton outlet pipe is connected to the lower cotton inlet, and a check valve is provided at the lower cotton inlet to prevent cotton lint from flowing back towards the fan.

[0014] Preferably, the machine body includes an upper box and a lower box, which are connected by bolts, and the cotton storage chamber is located in the upper box.

[0015] Implementing the embodiments of this utility model will have the following beneficial effects: After adopting the above-mentioned cotton filling machine, during use, the cotton filling nozzle can be inserted into the slot through the notch, connecting with the cotton filling port. At this time, turning the hand-adjusting bolt will cause its end to press against the edge of the cotton filling nozzle, so that the open end of the cotton filling nozzle is tightly pressed against the inner wall of the slot, locking the cotton filling nozzle at the cotton filling port, making the cotton filling nozzle and the cotton filling port tightly connected. While ensuring the connection stability of the cotton filling nozzle, it also takes into account the convenience of connection, overcoming the problem that the connection stability and connection efficiency of traditional connection methods are difficult to achieve at the same time, improving production efficiency and reducing equipment maintenance costs.

The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figure 1-5 As shown, a cotton filling machine includes a body 1, a filling mechanism, and a connecting mechanism. The body 1 has a cotton storage chamber 111, and a filling port 112 that connects to the cotton storage chamber 111 is opened on the front side of the body 1. The filling mechanism is used to drive the cotton wadding in the cotton storage chamber 111 to be evenly sprayed out from the filling port 112. The connecting mechanism includes a connecting seat 2 and at least two hand-adjusting bolts 25. The connecting seat 2 is fixed on the front side wall of the body 1 and covers the filling port 112. The connecting seat 2 has a slot 23 that connects to its side and is connected to the filling port 112. The front side wall of the connecting seat 2 has a notch 24 that connects to the slot 23. The two hand-adjusting bolts 25 are vertically screwed onto the front side of the connecting seat 2. The filling nozzles are evenly distributed on the wall and around the filling port 112. When in use, the filling nozzle a can be inserted into the slot 23 through the notch 24, and communicate with the filling port 112. At this time, turning the hand-adjusting bolt 25 can make its end press against the edge of the filling nozzle a, so that the open end of the filling nozzle a is tightly against the inner wall of the slot 23, locking the filling nozzle a at the filling port 112, so that the filling nozzle a and the filling port 112 are tightly connected. While ensuring the connection stability of the filling nozzle a, the convenience of connection is also taken into account. This overcomes the problem that the connection stability and connection efficiency of traditional connection methods are difficult to achieve at the same time, improves production efficiency, and reduces equipment maintenance costs.

[0023] In this embodiment, the slot 23 is connected to the upper side of the connector 2 so that the opening end of the filling nozzle a is inserted into the slot 23 from top to bottom, which is more in line with operating habits.

[0024] Specifically, the upper part of the body 1 is provided with at least one air inlet to balance the air pressure in the cotton storage chamber 111.

[0025] Furthermore, the connecting seat 2 includes a base plate 21 and a U-shaped baffle 22. The base plate 21 is fixed to the front side wall of the body 1 by screws and covers the cotton filling port 112. The front side wall of the base plate 21 has a receiving groove that connects to its side. The inner wall of the receiving groove has a connecting port that connects to the cotton filling port 112. The U-shaped baffle 22 is fixed to the front side wall of the base plate 21 by screws and forms a slot 23 with the inner wall of the receiving groove. The inner side of the U-shaped baffle 22 forms a notch 24. In actual use, since the cotton filling nozzle a is connected to the slot 23 by an insert, long-term friction will cause the inner wall of the slot 23 to wear to varying degrees, affecting the fit between the opening end of the cotton filling nozzle a and the inner wall of the slot 23. The connecting seat 2 is divided into multiple detachable parts, which makes it convenient for users to replace worn parts in a targeted manner, avoid cotton leakage, and ensure that the cotton filling nozzle a is tightly connected to the connecting port.

[0026] Furthermore, the filling mechanism includes a drive shaft 31, an agitator 32, a cotton-dispensing fan blade 33, an air nozzle 34, a drive component 35, and an air tank 36. The drive shaft 31 is horizontally rotatably disposed in the cotton storage chamber 111. The agitator 32 is Z-shaped, with its middle part fixedly connected to the middle part of the drive shaft 31. The cotton-dispensing fan blade 33 is disposed at one end of the drive shaft 31 near the filling port 112. The air nozzle 34 is disposed adjacent to the filling port 112 in the cotton storage chamber 111. The drive component 35 and the air tank 36 are both disposed in the machine body 1. The drive component 35 is used to drive the drive shaft 31 to rotate, so that the agitator 32 continuously agitates the cotton fibers in the cotton storage chamber 111 to prevent the cotton fibers from clumping, and drives the cotton-dispensing fan blade 33 to push the loosened cotton fibers toward the filling port 112. The air tank 36 supplies air to the air nozzle 34. The high-speed airflow ejected from the air nozzle 34 blows the cotton fibers from the filling port 112 to the filling nozzle a, completing the filling operation.

[0027] Furthermore, the end of the cotton-removing fan blade 33 away from the drive shaft 31 is provided with a serration 333. The serration 333 facilitates the pulling of cotton fibers by the end of the cotton-removing fan blade 33, improves the ability of the cotton-removing fan blade 33 to grasp cotton fibers, and ensures that the cotton fibers are transported to the air nozzle 34 in an orderly manner.

[0028] In this embodiment, the cross-section of the cotton-dispensing fan blade 33 is L-shaped. The blade of the cotton-dispensing fan blade 33 is divided into a dispensing page 331 and a retention page 332 by the bending line. The dispensing page 331 is parallel to the axis of the transmission shaft 31, and the retention page 332 is perpendicular to the axis of the transmission shaft 31. The dispensing page 331 is used to dispense and pick up cotton fibers and drive the cotton fibers to move towards the air nozzle 34, while the retention page 332 is used to prevent the cotton fibers from falling off the dispensing page 331 and improve the retention rate of cotton fibers on the dispensing page 331.

[0029] In this embodiment, the width of the agitator 331 gradually decreases from the end furthest from the drive shaft 31 toward the end closest to the drive shaft 31, to ensure that its far end has sufficient area for agitating the cotton, while its near end reduces the contact area with the cotton, thereby reducing the ineffective resistance of the blade, reducing the energy consumption of the motor, and improving economic efficiency.

[0030] Furthermore, the driving component 35 is a motor, which is built into the bottom of the machine body 1. One end of the transmission shaft 31 extends out of the cotton storage cavity 111 and is coaxially provided with a transmission wheel 37. The transmission wheel 37 is driven by the motor through a belt 38.

[0031] Furthermore, the cotton filling machine also includes a blower 4, which is built into the bottom of the machine body 1. The air inlet of the blower 4 is connected to a cotton inlet pipe 41 extending to the outside of the machine body 1, and the air outlet of the blower 4 is connected to an outlet pipe 42 extending upward and connecting to the cotton storage chamber 111. By integrating the blower 4 into the machine body 1, there is no need to configure an additional blower 4, which reduces the space occupied by the equipment, helps to keep the workshop clean, improves the space utilization of the workshop, and avoids the problems of efficiency interruption and lint pollution caused by traditional manual cotton filling by using a semi-automatic cotton filling method.

[0032] Furthermore, the end of the cotton inlet pipe 41 away from the blower 4 is connected to a feed hopper 43. The feed hopper 43 provides a wide "flare" which can naturally guide and collect cotton fibers from a larger range into the cotton inlet pipe 41, making it easier to sweep the dispersed cotton fibers into the hopper and greatly improving work efficiency.

[0033] Furthermore, a lower cotton inlet 113 is provided on the side wall of the cotton storage chamber 111, and the cotton outlet pipe 42 is connected to the lower cotton inlet 113. A check valve 44 is provided at the lower cotton inlet 113 to prevent cotton lint from flowing back towards the fan 4, so as to prevent the cotton lint in the cotton storage chamber 111 from flowing back into the cotton outlet pipe 42.

[0034] Furthermore, a pneumatic control panel 5 is provided on the front side wall of the machine body 1. The pneumatic control panel 5 integrates a pressure gauge 51 and a pressure regulating switch 52. The pressure gauge 51 is used to display the pneumatic pressure value of the air tank 36 in real time, and the pressure regulating switch 52 is used to adjust and limit the working pneumatic pressure of the air nozzle 34. The operator can directly and intuitively set and monitor the filling pneumatic pressure at the work station, which greatly improves the ease of operation and human-machine interaction experience, and ensures the consistency of filling quality.

[0035] Furthermore, the machine body 1 includes an upper box 11 and a lower box 12, which are connected by bolts. The cotton storage chamber 111 is located in the upper box 11. The drive shaft 31 and the air nozzle 34 are also located in the upper box 11, corresponding to the cotton storage chamber 111. The larger and heavier air tank 36, motor and fan 4 are located in the lower box 12. Through the modular structure of the upper and lower boxes 12, the flexibility of equipment transportation, installation and on-site layout is greatly improved. It effectively solves the limitations of traditional integrated cotton filling machines on transportation and usage scenarios, and significantly reduces the initial deployment cost and usage threshold of the equipment.

[0036] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model.
