Description

Technical Field

[0001] This utility model relates to the field of mud bag cutting and feeding, specifically an automatic mud bag feeding machine. Background Technology

[0002] Mud bags are containers made of special materials and filled with mud or other similar substances. They are commonly used in emergency situations such as flood control and disaster relief. When floods strike, they can be quickly stacked to form temporary dikes, preventing the spread of floodwaters and protecting people and property. They can also be used to reinforce dikes, riverbanks, and other hydraulic facilities, enhancing their stability and preventing collapses due to water erosion. Mud bags are simple to make, easy to use, and low in cost, playing an important role in responding to natural disasters and engineering construction, and are one of the commonly used materials in flood control and disaster relief work.

[0003] In the past, the processing of mud bags was characterized by low efficiency and difficulty in ensuring accuracy. Workers had to manually measure the length of the mud bags with their eyes and simple tools. This process not only consumed a lot of time and manpower, but also, due to the uncertainty of human factors, the measured length was prone to deviation. Workers also had to cut the mud bags with hand tools based on the measured length. The entire processing flow was very cumbersome, resulting in extremely low production efficiency. At the same time, manual cutting was difficult to control precisely, making it impossible for the mud bag length to reach the ideal standard, which affected product quality and production efficiency.

[0019] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0020] Please see Figures 1 to 5 As shown, this utility model provides a technical solution: an automatic mud bag feeding machine, including a shelf 1, a machine body 2 fixedly connected to the front end of the shelf 1, the machine body 2 including a machine base 21, the machine base 21 is hollow, a protective net 22 is fixedly connected to one side of the machine base 21, a cutting structure 23 is installed on the rear side of the machine base 21, and a rolling structure 24 is installed inside the machine base 21.

[0021] This material feeding machine has strong automation capabilities in the mud bag production process. On the one hand, it can accurately and efficiently perform automated flattening of the mud bag fabric, making the fabric that may have wrinkles or unevenness neat and smooth, preparing it for subsequent processing. On the other hand, it can cut the fabric into appropriate sizes evenly according to preset parameters. This process greatly reduces manual intervention, avoids errors and inefficiencies that may occur with manual operation, significantly improves the manufacturing efficiency of mud bags, and provides strong support for the high-quality development of the mud bag production industry.

[0022] A tensioning device 25 is fixedly located at the top center of the machine base 21. Two sets of support frames are fixedly connected to the front side of the top of the machine base 21, and a material tray 26 is rotatably connected between the two sets of support frames.

[0023] When in use, the fabric is wrapped and fixed on the surface of the tray 26, one end of the fabric is passed through the tensioning device 25 and placed inside the rolling structure 24. After the rolling structure 24 flattens the fabric, it is cut by the cutting structure 23 and then falls into the shelf 1 for subsequent processing.

[0024] The cutting structure 23 includes a first motor 231, a first motor bracket 232 fixedly connected to the bottom of the first motor 231, a bracket fixedly connected to the output shaft of the first motor 231, a connecting rod 233 rotatably connected to the front end of the bracket, a tool holder 234 rotatably connected to the front end of the connecting rod 233, two sets of tool holders 235 slidably connected to both sides of the tool holder 234, the tool holders 235 are fixed to the front end of the machine base 21 with bolts, an upper blade 236 is fixedly connected to the inner wall of the top of the tool holder 234, and a lower blade 237 is fixed to the front end of the machine base 21 with bolts, the lower blade 237 is located below the upper blade 236;

[0025] The rolling structure 24 includes a second motor 241, a second motor bracket 242 fixedly connected to the bottom end of the second motor 241, a first rotating shaft 243 fixedly connected to the output shaft of the second motor 241, two sets of first limiting seats 248 fixedly connected to the top end of the machine base 21, a drive rod 246 rotatably connected inside the two sets of first limiting seats 248, a lower rolling wheel 247 fixedly connected to the outside of the drive rod 246, a second rotating shaft 245 fixedly connected to one end of the drive rod 246, and a belt 244 sleeved on the outer wall of the second rotating shaft 245 and the first rotating shaft 243;

[0026] The top of the machine base 21 is fixedly connected to a limiting frame 249. Two sets of second limiting seats 2410 are fixedly connected inside the limiting frame 249. An upper rolling roller 2411 is rotatably connected inside the two sets of second limiting seats 2410. The upper rolling roller 2411 is located above the lower rolling roller 247.

[0027] The first motor bracket 232 and the second motor bracket 242 are both fixedly connected to the inner wall of the bottom of the machine base 21, and the protective net 22 is sleeved on the outside of the first rotating shaft 243, the belt 244 and the second rotating shaft 245.

[0028] When the fabric is rolled, the second motor 241 drives the first rotating shaft 243 to rotate. The first rotating shaft 243 drives the second rotating shaft 245 to rotate synchronously via the belt 244. The second rotating shaft 245 drives the drive rod 246 and the lower rolling roller 247 to rotate synchronously. When the lower rolling roller 247 rotates, it will synchronously drive the upper rolling roller 2411 to rotate. At this time, the fabric placed between the lower rolling roller 247 and the upper rolling roller 2411 is moved forward to the cutting structure 23 under the drive of the lower rolling roller 247 and the upper rolling roller 2411. The two sets of rolling rollers can roll the fabric flat.

[0029] When cutting the fabric, the first motor 231 drives the bracket to rotate. When the bracket rotates, it will cause one end of the connecting rod 233 to swing, and the other end of the connecting rod 233 will swing synchronously. This will enable the knife holder 234 to move up and down inside the two sets of knife fixing frames 235. When the knife holder 234 moves up and down, it will drive the upper blade 236 to move synchronously. At this time, the fabric located between the upper blade 236 and the lower blade 237 will be cut by the movement of the upper blade 236.

[0030] After the fabric is cut, it will slide down the slope of shelf 1 to the bottom of shelf 1 for easy collection and processing later.

[0031] The machine base 21 also houses an electrical control box, which consists of a three-pole air main switch, a 3kW frequency converter, a control transformer, a three-phase solid-state relay, two single-phase relays, and two intermediate relays. The electrical control box mainly controls the on / off state of the circuit, protects the circuit safety, and distributes power. It also works in conjunction with the infrared position sensor at the mounting shelf 1 to achieve automated control. This device uses the infrared sensor to collect the object obstruction signal, and in conjunction with the microcontroller counting pulse, it triggers a zeroing process after reaching the set length, thereby cutting the mud bag with the cutter.

[0032] The air switch is responsible for connecting and disconnecting the power supply. It automatically trips when the circuit experiences faults such as load or short circuit, protecting the entire electrical control box and equipment. The single-phase relay is responsible for detecting single electrical parameters in the circuit, such as current and voltage. When the parameters are abnormal, it sends a signal to protect the circuit. The control transformer is responsible for converting the input high voltage into a low voltage suitable for the control circuit, providing a stable working power supply for control components such as intermediate relays and solid-state relays. The intermediate relay is responsible for receiving signals from the infrared sensor, amplifying and converting the signals so that the frequency converter can change the operating state of the motor. The frequency converter is responsible for receiving signals from the intermediate relay to change the power supply frequency and voltage of the motor. Then, the solid-state relay uses solid-state electronic components to achieve contactless on / off control of the motor's start and stop, thereby controlling the cutting of the tool.

[0033] Working principle: The rotation of the second motor 241, controlled by the electrical control box, propels the mud bag forward. Infrared sensors are installed at equal intervals at shelf 1. As the mud bag passes by, it sequentially blocks the light from the infrared sensors at different positions. By recording the time sequence and interval of the mud bag blocking each sensor, length detection is achieved. The intermediate relay in the electrical control box receives the weak electrical signal from the infrared sensor, amplifies and converts the signal, and transmits it to the frequency converter to convert the fixed frequency and voltage AC power into adjustable frequency and voltage AC power. Then, the fixed relay is used to precisely start and stop the first motor 231, thereby controlling the cutting frequency of the upper blade 236.
