Technical Field

[0001] This utility model relates to the technical field of putty powder production equipment, and in particular to a continuous feeding device for putty powder production. Background Technology

[0002] Putty powder is a building decoration material, generally composed of base material, filler, additives and water. Currently, the commonly used putty powders on the market are roughly divided into two types: lime-based putty powder and gypsum-based putty powder. Lime-based putty powder contains lime powder, heavy calcium carbonate, hydroxypropyl methylcellulose, redispersible latex powder, bentonite, etc. Gypsum-based putty powder contains gypsum powder, cellulose, heavy calcium carbonate, retarder, etc. When producing different types of putty powder, materials need to be added according to different proportions and then mixed to finally obtain the finished putty powder.

[0003] Some putty powder fillers or additives are usually packaged in bags. When feeding, the bags need to be opened manually and fed into the mixing equipment through a conveying device. However, manual opening of bags is inefficient, labor-intensive, and the dust can easily cause harm to workers. Therefore, this application proposes a feeding device that can automatically open bags.

The other ends of the two traction ropes pass through the top of the feeding box and are fixed to the ends of the two carrier nets away from the cutting blade.

[0008] In some embodiments, the clamping pliers rotate inside a connecting frame via a connecting shaft, the connecting frame being a U-shape with the opening facing upwards, and the clamping pliers and the connecting shaft being driven to rotate by a third drive motor.

[0009] In some embodiments, the clamping clamp includes two clamping rods that are staggered. The end of the clamping rod near the feeding box is the clamping end. The lower clamping rod is fixedly mounted on the surface of the connecting shaft, and the upper clamping rod rotates on the surface of the connecting shaft. An electric push rod is provided at the end of the two clamping rods away from the feeding box for driving the two clamping rods to perform clamping actions.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-7 A continuous feeding device for putty powder production includes a feeding box 1 and a conveying pipe 2 fixed at the lower end of the feeding box 1. The lower end of the feeding box 1 is funnel-shaped and connected to the conveying pipe 2. A spiral auger 201 rotates inside the conveying pipe 2. The spiral auger 201 is driven by a first drive motor, which is fixed at the lower end of the conveying pipe 2. A discharge port is provided at the upper end of the conveying pipe 2. An inlet is provided on the side of the feeding box 1 away from the conveying pipe 2. A cutting blade 3 is fixed inside the feeding box 1. The cutting blade 3 is perpendicular to the inlet and its height is lower than that of the inlet. Two carrying nets 4 are provided inside the feeding box 1. The two carrying nets 4 are symmetrically arranged with the cutting blade 3 as the center and their height is lower than that of the cutting blade 3. The two carrying nets 4 are hinged to each other at one end inside the feeding box 1.

[0026] Understandably, the packaged raw materials are transported to the feeding box 1 by the conveyor belt and fall onto the surface of the two carrier nets 4. The lower surface of the packaging is cut open from the middle by the cutting blade 3, allowing the raw materials to leak out and fall into the bottom of the feeding box 1 through the carrier nets 4. The raw materials are then lifted upward by the spiral auger 201 and fed into the mixing device.

[0027] Specifically, the upper surface of the feeding box 1 is provided with a traction assembly 5 for driving the two supporting nets 4 to rotate. The traction assembly 5 includes two winding wheels 501 rotating on the upper surface of the feeding box 1 and two traction ropes 503 respectively wound around the surfaces of the two winding wheels 501. The two winding wheels 501 are fixedly mounted on the surface of the rotating shaft, which is fixed on the upper surface of the feeding box 1. Two guide wheels 502 are symmetrically fixed on the upper surface of the feeding box 1. The two traction ropes 503 are respectively laid on the surfaces of the two guide wheels 502. The other ends of the two traction ropes 503 pass through the top of the feeding box 1 and are fixed to the ends of the two supporting nets 4 away from the cutting blade 3. The rotating shaft is driven to rotate by a second drive motor.

[0028] Understandably, the second drive motor drives the rotating shaft and the two winding wheels 501 to rotate, causing the two winding wheels 501 to simultaneously wind the two traction ropes 503, thereby causing the two traction ropes 503 to pull the two carrying nets 4 to rotate, causing the two carrying nets 4 to fold in half, thereby causing the packaging bag of the raw material to fold in half, so that the cut on the lower surface of the packaging bag faces downward, making it easier to quickly discharge the raw material inside the packaging bag.

[0029] Specifically, a clamping clamp 8 for pulling packaging bags out of the feeding box 1 is provided on the side near the conveying pipe 2. The clamping clamp 8 rotates inside the connecting frame 7 via the connecting shaft 6. The connecting frame 7 is U-shaped with the opening facing upwards. The clamping clamp 8 and the connecting shaft 6 are driven to rotate by a third drive motor. The clamping clamp 8 includes two clamping rods 801 that are staggered. The clamping rod 801 near the feeding box 1 is the clamping end. The lower clamping rod 801 is fixedly mounted on the surface of the connecting shaft 6, and the upper clamping rod 801 is fixedly mounted on the surface of the connecting shaft 6. The clamping rod 801 rotates on the surface of the connecting shaft 6. When the lower clamping rod 801 is inserted into the feeding box 1, it is close to the upper surface of the horizontal bearing plate 4. This is to facilitate the insertion of the lower clamping rod 801 under the packaging bag when clamping the packaging bag. The two clamping rods 801 are provided with an electric push rod 802 at the end away from the feeding box 1 to drive the two clamping rods 801 to perform clamping action. The two ends of the electric push rod 802 are respectively hinged to the ends of the two clamping rods 801 away from the feeding box 1.

[0030] Understandably, the operation of the electric push rod 802 drives the upper clamping rod 801 to rotate, thereby cooperating with the lower clamping rod 801 to open and close the clamping ends of the two clamping rods 801, facilitating the clamping of the packaging bag. The operation of the third drive motor drives the connecting shaft 6 and the two clamping rods 801 to rotate, causing the clamping ends of the two clamping rods 801 to rotate downwards, thereby completely pulling the packaging bag that has been partially pulled out of the feeding box 1 out of the feeding box 1, preventing the packaging bag from affecting the subsequent feeding of raw materials in the feeding box 1.

[0031] Specifically, a displacement component 9 is fixed on the side of the feeding box 1 near the conveying pipe 2. The displacement component 9 includes a slide 901 for sliding the connecting frame 7. The two ends of the slide 901 are fixed to the side of the feeding box 1 near the conveying pipe 2 and the surface of the conveying pipe 2, respectively. A threaded column 902 is rotatably mounted on the upper surface of the slide 901. A moving block 903 is threadedly connected to the surface of the threaded column 902. A through groove for moving the connecting frame 7 is opened on the surface of the slide 901. One end of the connecting frame 7 slides on the inner wall of the through groove. The lower end of the moving block 903 is fixed to the end of the connecting frame 7 that slides on the inner wall of the through groove. The threaded column 902 is driven to rotate by a fourth drive motor. An opening for the clamping clamp 8 to enter and exit is opened on the side of the feeding box 1 near the conveying pipe 2.

[0032] Under normal conditions, the clamping pliers are located outside the feeding box 1. The fourth drive motor works to drive the threaded column 902 to rotate, which causes the moving block 903 to drive the connecting frame 7 to move on the surface of the slide 901. This allows the connecting frame 7 to drive the clamping end of the clamping pliers 8 to enter and exit the feeding box 1, making it easier to pull out the packaging bag inside the feeding box 1.

[0033] Specifically, a dust collection assembly 10 is provided in front of the feeding box 1. The dust collection assembly 10 includes a dust collection hood 1001 fixed in front of the feeding box 1. The dust collection hood 1001 is L-shaped and connected to the feeding box 1. The air inlet of the dust collection hood 1001 is close to the feeding port of the feeding box 1. A filter screen 1002 is provided inside the dust collection hood 1001 and is located at the bend of the dust collection hood 1001. The dust collection hood 1001 is divided into a dust collection chamber and a negative pressure chamber by the filter screen 1002. An air pump is fixed in front of the feeding box 1 and the air inlet of the air pump is connected to the negative pressure chamber of the dust collection hood 1001. A collection box 1003 is slidably provided at the bottom of the dust collection chamber of the dust collection hood 1001.

[0034] Understandably, by operating the air pump, air is extracted from the negative pressure chamber to create negative pressure, which allows the dust hood 1001 to absorb the dust floating in the feeding box 1. The dust is then intercepted by the filter screen 1002, causing it to remain in the dust collection chamber. The dust is then collected by the collection box 1003, which is then pulled out of the dust hood 1001 for easy cleaning.

[0035] In use, this invention transports packaged raw materials to the feeding box 1 via a conveyor belt, where they fall onto the surfaces of two support nets 4. A cutting blade 3 cuts the lower surface of the packaging in half, allowing the raw materials to leak out and fall through the support nets 4 into the bottom of the feeding box 1. A first drive motor then rotates the auger 201, lifting the raw materials upwards and feeding them into the mixing device. Next, a second drive motor rotates the shaft and two winding wheels 501, causing the two winding wheels 501 to simultaneously engage the two traction ropes 50... 3. The two supporting nets 4 are folded at 45 degrees using two traction ropes 503, which in turn folds the raw material packaging bag so that the cut on the bottom surface of the packaging bag faces downwards, facilitating the rapid discharge of the raw material inside the packaging bag. After discharge, the supporting nets 4 are laid flat. At the same time, the air pump is used to extract the air from the negative pressure chamber to create negative pressure, thereby allowing the dust hood 1001 to absorb and collect the dust floating in the feeding box 1, preventing the dust from being dispersed in large quantities through the feed inlet, which would worsen the working environment and affect the health of the workers. The drive motor rotates the threaded column 902, causing the moving block 903 to move the connecting frame 7 on the surface of the slide 901. This causes the connecting frame 7 to move the clamping end of the clamping pliers 8 into the feeding box 1. The electric push rod 802 then rotates the clamping rod 801 located above, causing the clamping ends of the two clamping rods 801 to open and continue to penetrate deeper into the feeding box 1. This squeezes the packaging bag against the clamping ends, ensuring that the clamping rods 801 clamp the packaging bag. Finally, the clamping ends of the two clamping rods 801... The packaging bag is clamped by the threaded column 902, which drives the connecting frame 7 and the clamping clamp 8 to move outward. When the clamping end of the clamping clamp 8 moves out of the feeding box 1, the packaging bag is pulled out partially. The third drive motor then rotates the connecting shaft 6 and the two clamping rods 801, causing the clamping ends of the two clamping rods 801 to rotate downward. This completely pulls the packaging bag, which has already been partially pulled out of the feeding box 1, out of the feeding box 1, preventing the packaging bag from affecting the subsequent feeding of raw materials and achieving the purpose of continuous feeding.
