[0002] In the production process of coatings, a large amount of powder raw materials are required, and most of the purchased raw materials are packaged according to specifications. In actual use, the hopper is usually cut with a knife before the raw material is lifted and poured into the hopper. This method is relatively simple, but it also has certain drawbacks. In particular, the process of opening the bag and then pouring the material requires careful lifting and pouring. If the operation is not done properly, the raw material can easily spill outside, requiring cleaning or even recycling and secondary processing before it can be used, which affects the overall efficiency. Therefore, it needs to be improved. Utility Model Content

[0006] In a preferred embodiment of this invention, the supporting mesh frame includes a first mesh frame, a second mesh frame, and a rotating shaft. The first mesh frame and the second mesh frame are rotatably connected by the rotating shaft. The side of the first mesh frame and the second mesh frame away from the rotating shaft is inclined upward and respectively mounted on the top of both sides of the hopper. The rotatable connection between the first mesh frame and the second mesh frame forms a V-shaped concave area. The first mesh frame and the second mesh frame are provided with a feeding port on the side near the rotating shaft. The cutting roller is rotatably mounted on the bottom surface of the first mesh frame through a bearing. The driving structure is mounted on the bottom surface of the first mesh frame.

[0007] In a preferred embodiment of this invention, the first mesh frame has a plurality of first discharge ports arranged in an array along its length on the side near the rotating shaft; the second mesh frame has a plurality of second discharge ports arranged in an array along its length on the side near the rotating shaft; the opening widths of the first and second discharge ports are the same, and the array spacing of the first and second discharge ports is the same; the opening ends of the first and second discharge ports are provided with corresponding circular holes; the first and second discharge ports are staggered and interlocked, and are rotatably connected by a rotating shaft passing through the circular holes.

[0008] In a preferred embodiment of this invention, two support blocks are included, and the top of each support block is provided with a V-shaped groove. The support blocks are fixedly installed on the inner wall of the hopper by bolts, and the groove is used to support the bottom of the rotating connection between the first and second mesh frames.

[0009] In a preferred embodiment of this invention, the cutting roller includes a support shaft, on which a plurality of blades are fixedly arranged in an array along the length direction, the positions of the blades corresponding to the positions of the first feed inlet; the top of the blades is a semi-circular first cutting part, and the bottom is a quarter-circular second cutting part; the center of the first cutting part coincides with the axis of the support shaft; the radius of the second cutting part is twice the radius of the first cutting part, and the center of the second cutting part falls on the bottom of the first cutting part on the side away from the rotating shaft.

[0012] The beneficial effects of this utility model are as follows:

[0013] This utility model provides an add-on bag-breaking device, including a support frame, a cutting roller, and a drive structure. The inner bottom surface of the support frame has a V-shaped concave structure, and there are feeding ports on both sides of the concave area.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 4 As shown in the figure, a specific embodiment of the present invention discloses an add-on bag-breaking device, including a support frame 100, a cutting roller 200, and a drive structure 300; the inner bottom surface of the support frame 100 has a V-shaped concave structure, and both sides of the concave area are provided with a discharge port; the cutting roller 200 is rotatably mounted on the bottom surface of the support frame 100 through bearings, and the blade of the cutting roller is set corresponding to the discharge port; the drive structure 300 is mounted on the bottom surface of the support frame 100 and is used to drive the cutting roller 200 to rotate; the blade only passes through the top of the discharge port when the cutting roller rotates.

[0024] The aforementioned add-on bag-breaking device has a relatively simple overall structure and can be used as an add-on for convenient on-demand application. Its recessed area facilitates the sliding of bagged material towards the bottom and close to the cutting roller. The cutting roller rotates under the drive of the drive structure to cut and break the bagged material, allowing the internal material to be smoothly discharged and fall out. The overall operation is simple, effectively preventing the problem of raw materials scattering or falling out, reducing the probability of additional cleaning or secondary processing, thereby improving overall efficiency.

[0025] The blade only protrudes from the top of the feed inlet when the cutting roller rotates, which means that it is retracted inside the support frame during the rest of the standby time and is not exposed to the outside, which can improve the safety of use.

[0026] Furthermore, it also includes a controller and a foot switch (not shown). Both the foot switch and the drive structure are electrically connected to the controller. The foot switch is used to control the power supply to the drive structure. The operator starts the drive structure by stepping on the foot switch, thereby driving the cutting roller to rotate a preset number of times to cut and break the bagged material placed in the concave area. It should be noted that the foot switch is a common switch structure with a simple power connection method and can be purchased and used on the market. Specific details will not be elaborated here.

[0027] Furthermore, such as Figure 2 , Figure 3As shown, the support frame 100 includes a first frame 110, a second frame 120, and a rotating shaft 130. The first frame 110 and the second frame 120 are rotatably connected via the rotating shaft 130. The sides of the first frame 110 and the second frame 120 away from the rotating shaft are inclined upwards and respectively mounted on the top of both sides of the hopper. The rotatable connection between the first frame and the second frame forms a V-shaped concave area. The first frame and the second frame are provided with a discharge port on the side near the rotating shaft. The cutting roller 200 is rotatably mounted on the bottom surface of the first frame 110 via a bearing. The drive structure 300 is mounted on the bottom surface of the first frame 110. A first hanging plate is fixedly provided on the top of the side of the first frame away from the rotating shaft, and a second hanging plate is fixedly provided on the top of the side of the second frame away from the rotating shaft. Figure 4 As shown, the first and second hanging plates are placed on the top surface of the hopper opening and are close to the top of the corresponding side wall of the hopper opening. They are fixedly connected by screws to provide a stable connection. Furthermore, the first and second mesh frames are rotatably connected, and the cutting roller and drive structure are installed on the bottom surface of the first mesh frame. During maintenance, the first mesh frame can be flipped to expose the part to be maintained, which is convenient for actual operation.

[0028] Furthermore, the first mesh frame 110 has multiple first discharge ports 111 arranged in an array along its length on the side near the rotating shaft; the second mesh frame 120 has multiple second discharge ports 121 arranged in an array along its length on the side near the rotating shaft; the opening widths of the first discharge ports 111 and the second discharge ports 121 are the same, and the array spacing of the first discharge ports 111 is the same as the array spacing of the second discharge ports 121; the opening ends of the first and second discharge ports are provided with corresponding circular holes; the first discharge ports 111 and the second discharge ports 121... The meshes are arranged in a staggered and interlocked manner, and are rotatably connected by a rotating shaft 130 passing through a circular hole. One end of the rotating shaft is fixed with a circular plate, and the other end is fixed with a threaded post. A nut is installed on the threaded post, so that the rotating shaft can be rotatably mounted on the first mesh frame and the second mesh frame. The first mesh frame and the second mesh frame use the first discharge port and the second discharge port as the interface for cooperation, which can not only meet the required rotational cooperation effect, but also make the discharge port part as close as possible to the bottom position, maintain normal material dropping and discharging action, and reduce material retention.

[0029] Furthermore, it includes two support blocks 400, with a V-shaped groove 410 on the top of each support block 400. The support blocks are fixedly installed on the inner wall of the hopper by bolts. The groove 410 is used to support the bottom of the rotating connection between the first grid frame 110 and the second grid frame 120, so that the grid frame can be installed stably, the overall load-bearing capacity can be strengthened, the problem of bending and deformation caused by concentrated force on the rotating shaft can be prevented, and the rotating connection between the first grid frame and the second grid frame can be maintained.

[0030] Furthermore, such as Figure 5As shown, the cutting roller 200 includes a support shaft 210, on which a plurality of blades 220 are fixedly arranged in an array along the length direction. The position of the blades 220 corresponds to the position of the first feed port 111, providing cutting at multiple parts, effectively expanding the cutting range, and improving the efficiency and quality of bag breaking. The top of the blade 220 is a semi-circular first cutting part 221, and the bottom is a quarter-circular second cutting part 222. The center of the first cutting part 221 coincides with the axis of the support shaft 210. The radius of the second cutting part 222 is twice the radius of the first cutting part 221, and the center of the second cutting part falls on the bottom of the first cutting part on the side away from the rotating shaft. When the cutting roller is in the initial position, the top of the first cutting part is located inside the first feed port and does not extend beyond the top of the first feed port. When the cutting roller rotates, the rear end of the first cutting part rotates and extends beyond the top of the first feed port, and the subsequent second cutting part extends a larger range, thereby effectively breaking the material bag.

[0031] Furthermore, the first cutting section 221 has a thin sheet structure; the top of the second cutting section 222 near the rotating shaft 130 is connected to the first cutting section 221, and the thickness gradually increases towards the bottom. This design allows for rapid tearing of the bag through the first cutting section and then expansion through the second cutting section, effectively increasing the range of bag breaking, ensuring the efficiency and quality of bag breaking, and allowing the internal material to fall and be discharged fully.

[0032] Furthermore, the drive structure 300 includes a geared motor 310 and a protective cover 320; the protective cover 320 is bolted to the bottom of the first grid frame 110, the geared motor 310 is installed inside the protective cover 320, the output shaft of the geared motor 310 is sealed through the outside of the protective cover 320, and a first pulley 510 is fixedly installed at its end; a second pulley 520 is correspondingly fixed on the support shaft 210, and the second pulley 520 and the first pulley 510 are connected by a synchronous belt 530; the protective cover includes a box body with one end open, a cover is installed outside the opening of the box body, the cover has a wire hole, and a wire plug is installed at the wire hole; the controller and the geared motor are installed inside the box body, the geared motor is electrically connected to the controller, and the controller... The wiring plug extends outward and connects to the foot switch, which is powered externally, allowing the device to be started by stepping on the foot switch. A perforation is located on the end face of the housing away from the open opening. An extended tube is fixed to the outside of the perforation, and multiple sealing rings are fixed to the inner wall of the extended tube. The output shaft of the geared motor extends outward through the extended tube and forms a rotational seal with the sealing rings. The protective cover is a split structure, allowing for easy disassembly and assembly, facilitating the inspection or replacement of internal electrical components. It should be noted that the hopper feeding is not continuous; only a certain amount needs to be added each time. This means the geared motor does not operate continuously for extended periods, eliminating the need to consider heat dissipation. Therefore, a relatively enclosed protective cover can be used for dust protection.

[0033] Furthermore, the width of the first mesh frame is smaller than that of the second mesh frame, and the first mesh frame is located on the side of the hopper closer to the worker's position. On the one hand, this makes it convenient for workers to put heavier bagged materials into the closer cutting area. On the other hand, during subsequent maintenance, the drive structure and cutting roller installed on the first mesh frame can be inspected or replaced by flipping it over separately, which is convenient for actual operation.

[0034] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. This utility model is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are all within the protection scope of this utility model.
