Description

Technical Field

[0001] This utility model belongs to the field of down jacket technology, and relates to filling devices, specifically an automatic weighing and filling device for down jackets. Background Technology

[0002] The automatic weighing and filling device for down jackets is an automated piece of equipment used in down jacket production, capable of precisely controlling the amount of down filling. Equipped with a weighing system, control system, conveying system, and interface system, this device ensures the consistency of warmth and quality in each down jacket by monitoring and adjusting the down filling amount in real time, thereby improving production efficiency and reducing human error.

[0003] However, some existing automatic weighing and filling devices are prone to down residue in their weighing chambers. This is because down has a certain static electricity, which causes it to adhere to the walls of the weighing chamber, resulting in residue. This residue leads to inconsistent filling amounts in each down jacket, affecting the product's warmth and overall quality. Therefore, this problem needs to be solved. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic weighing and filling device for down jackets. The technical problem this invention aims to solve is that static electricity causes down to adhere to the wall surface inside the weighing chamber, resulting in residue. This down residue leads to inconsistent filling amounts in each down jacket, thus affecting the product's warmth retention and overall quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic weighing and filling device for down jackets includes a housing with a storage compartment on one side. Four support plates are fixedly connected inside the storage compartment, and three weighing compartments are arranged between the four support plates. Each of the three weighing compartments has a support mechanism on its surface for supporting the weighing compartment. Each of the three weighing compartments is rotatably connected to a guide tube, and the guide tubes are configured to cooperate with the weighing compartments. Each of the three guide tubes has multiple air nozzles on its surface, and each of the three guide tubes has a rotating mechanism at its top for rotating the guide tube. The guide tubes prevent down from adhering to the inner wall of the weighing compartment.

[0007] As a further embodiment of this utility model, the support mechanism includes two weighing plates, both of which are fixedly connected to the surface of the weighing chamber. Each of the two support plates has a slot on its surface near the weighing plates, and two pressure sensors are fixedly connected inside each slot. The weighing plate is fixedly connected to the top of the two pressure sensors. Two symmetrical flow guides are symmetrically opened on the top of the weighing chamber, and a screen is fixedly connected inside each flow guide. Through the arrangement of the weighing plates, the weighing chamber can be symmetrically supported.

[0008] As a further embodiment of this utility model, the rotating mechanism includes a geared disc, which is fixedly sleeved on the surface of the guide pipe. A motor is fixedly connected to the top of the weighing chamber, and a gear is fixedly connected to the output shaft of the motor via a coupling. The gear and the geared disc are configured to cooperate with each other. A rotary joint is provided at the end of the guide pipe near the geared disc. A feed pipe is provided on the surface of the weighing chamber near the screen. A return pipe is provided at the bottom of the weighing chamber. A filling pipe is provided on the surface of the weighing chamber away from the return pipe. Four universal wheels are provided at the bottom of the housing, and the four universal wheels are evenly arranged in a square shape. A counterweight is fixedly connected to the top of the weighing chamber on the side away from the motor.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. This utility model employs a technical solution of installing a guide pipe inside the weighing chamber, which effectively prevents down from adhering to the inner wall of the weighing chamber. This solves the problem of static electricity causing down to adhere to the wall surface inside the weighing chamber, resulting in residue. Down residue leads to inconsistent filling volume in each down jacket, affecting the product's warmth retention and overall quality. The guide pipe is installed inside the weighing chamber and is connected to an external air pump via a rotary joint. Multiple air nozzles are provided on the surface of the guide pipe, allowing air to be introduced into the weighing chamber. The airflow causes the down to circulate in the air, reducing the contact time with the weighing chamber wall and lowering the possibility of static electricity accumulation. The moving air may also help carry away some static charge, thus neutralizing static electricity and ensuring that down does not adhere to the inside of the weighing chamber. Because the guide pipe is also connected to the geared disc, it rotates synchronously when the geared disc rotates, ensuring thorough cleaning of the weighing chamber's interior.

Four support plates 103 are fixedly connected inside the storage compartment 101. Three weighing compartments 2 are arranged between the four support plates 103. Each of the three weighing compartments 2 has a support mechanism on its surface for supporting the weighing compartment 2. Each of the three weighing compartments 2 is rotatably connected to a guide pipe 303, and the guide pipe 303 is configured to cooperate with the weighing compartment 2. Each of the three guide pipes 303 has multiple air nozzles 304 on its surface. The air nozzles 304 allow air to enter the weighing compartment 2. Each of the three guide pipes 303 has a rotating mechanism at its top for rotating the guide pipe 303. The guide pipes 303 prevent down from adhering to the inner wall of the weighing compartment 2.

[0018] Preferably, the support mechanism includes two weighing plates 201, both of which are fixedly connected to the surface of the weighing chamber 2. Each of the two support plates 103 has a slot 104 on its surface near the weighing plates 201. Two pressure sensors 202 are fixedly connected inside each slot 104. The weighing plates 201 are fixedly connected to the top of the two pressure sensors 202. The pressure sensors 202 allow for weighing of the down filling amount. Two symmetrical flow guides 207 are symmetrically opened on the top of the weighing chamber 2. Screens 208 are fixedly connected inside each flow guide 207. The weighing plates 201 provide support for the weighing chamber 2.

[0019] Preferably, the rotating mechanism includes a gear disc 302, which is fixedly sleeved on the surface of the guide pipe 303. A motor 3 is fixedly connected to the top of the weighing chamber 2. The output shaft of the motor 3 is fixedly connected to a gear 301 through a coupling. The gear 301 and the gear disc 302 are configured to cooperate with each other. A rotary joint 305 is provided at the end of the guide pipe 303 near the gear disc 302. A feed pipe 203 is provided on the surface of the weighing chamber 2 near the screen 208. A return pipe 204 is provided at the bottom of the weighing chamber 2. A filling pipe 205 is provided on the surface of the weighing chamber 2 away from the return pipe 204. Four universal wheels 102 are provided at the bottom of the housing 1, and the four universal wheels 102 are evenly arranged in a square shape. A counterweight 206 is fixedly connected to the top of the weighing chamber 2 away from the motor 3. The guide pipe 303 can be rotated by the gear disc 302.

[0020] Working principle: During use, connect the external pipe to the feed pipe 203, return pipe 204, filling pipe 205, and rotary joint 305. After preparation, reset the pressure sensor 202 to zero, and then it can work normally. During the filling process, the motor 3 will start. A gear 301 is installed on the output shaft of the motor 3, and the gear 301 cooperates with the gear plate 302 on the top of the weighing chamber 2. When the gear 301 rotates, the gear plate 302 will rotate synchronously.
