Description

Technical Field

[0001] This utility model relates to the field of unpacking machines, specifically to a new type of automatic unpacking machine. Background Technology Automatic unpacking machines are key equipment in industrial production lines used for the automated processing of bagged powder or granular materials. Their core function is to safely and efficiently separate materials from packaging bags through mechanization, while solving the pain points of manual unpacking. They achieve a fully automated production line of "unpacking, conveying, and feeding" by directly connecting to conveyor belts, pneumatic conveying pipelines, or storage silos. They use rotating blades, hooks, or laser cutting systems to precisely cut woven bags or paper bags, and then completely separate the materials from the packaging bags through vibrating screening or centrifugal swinging.

[0002] When existing bag-breaking equipment breaks bags, materials naturally fall out from the opening. When the bag contains granular materials, these falling materials inevitably roll around. If they roll into the gaps in the internal structure of the equipment, they are difficult to clean and result in waste. Utility Model Content

[0003] Based on the above description, this utility model provides a new type of automatic unpacking machine to solve the problem that granular materials roll on the conveyor belt during the unpacking process of existing unpacking machines.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A novel automatic unpacking machine includes a belt conveyor and a pack breaking device. One end of the belt conveyor is connected to the inlet of the pack breaking device. A rotating screen is installed at one end of the pack breaking device. A screw conveyor is installed at the bottom of the rotating screen. A pulse dust collector is installed at the top of the rotating screen. The bag-breaking device includes a conveying section, a cutting section, and a housing. One side of the housing is fixedly connected to the side wall of the rotating screen. The conveying section is installed inside the housing, and the cutting section is installed on the side wall of the housing. The conveying unit includes a conveyor belt, a limiting plate, a groove, and a gear. The limiting plate is installed on the top of the conveyor belt, the groove is formed on the top surface of the limiting plate, the gear meshes with the conveyor belt, and one end of the gear is connected to the output end of a stepper motor via a rotating shaft. The stepper motor is installed on the side wall of the housing.

[0005] Furthermore, the cutting part includes a cutting disc and a motor. One end of the cutting disc is movably mounted on the inner wall of the housing via a rotating shaft, and the rotating shaft on the cutting disc passes through the side wall of the housing and is connected to the output end of the motor.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the conveying unit also includes a baffle plate, which is mounted on the conveyor belt and one side of the baffle plate is fixedly connected to the end face of the limiting plate.

[0008] Furthermore, the number of limiting plates is several, and the several limiting plates are evenly arranged on the conveyor belt, with a gap between every two limiting plates.

[0009] Furthermore, the conveying unit also includes a limiting block, which is installed on the top surface of the limiting plate, and the cross-section of the limiting block is designed as a triangle.

[0010] Furthermore, the conveying unit also includes a partition plate, which is installed on the top surface of the conveyor belt, and the partition plate and the limiting plate are arranged at intervals.

[0011] Furthermore, the bottom of the cutting disc is inserted into the inner cavity of the groove, and the groove is located in the middle of the limiting plate.

[0012] Furthermore, the partition is made of rubber, and both ends of the partition are connected to the sidewalls of the baffle. The two ends of the partition are designed to be pleated.

[0013] Furthermore, one end of the conveyor belt is connected to the belt conveyor, while the other end of the conveyor belt is connected to the inlet of the rotating screen.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: 1. This utility model, by setting a limiting plate on the conveyor belt and opening a groove on the limiting plate, can use the limiting plate to block granular materials, and the groove can conform to the cutting work of the cutting disc, so that the cutting work occurs above the groove. When the cutting is completed, it can pick up the granular materials and prevent the granular materials from rolling around randomly.

[0015] 2. By setting baffles at both ends of the limiting plate, and in conjunction with partitions connected to the baffles, the granular material can be blocked in the front and rear directions, keeping the granular material within the enclosure of the limiting plate and partitions, thus blocking the granular material from rolling into the gap outside the conveyor belt and preventing it from being transported by the conveyor belt to the rotating screen for separation.

[0023] Please see Figure 1 , Figure 2 and Figure 4 A novel automatic unpacking machine includes a belt conveyor 1 and a pack breaking device 8. One end of the belt conveyor 1 is connected to the inlet of the pack breaking device 8. A rotating screen 3 is installed at one end of the pack breaking device 8. A screw conveyor 5 is installed at the bottom of the rotating screen 3. A pulse dust collector 4 is installed at the top of the rotating screen 3. The material bag is conveyed from the belt conveyor 1 to the pack breaking device 8. After being broken by the pack breaking device 8, it is conveyed to the rotating screen 3. After the rotating screen 3 separates the broken material bag from the material, the material enters the screw conveyor 5 and is conveyed to the next process. The bag breaking device 8 includes a conveying part 2, a cutting part 6, and a housing 7. One side of the housing 7 is fixedly connected to the side wall of the rotating screen 3. The conveying part 2 is installed inside the housing 7, and the cutting part 6 is installed on the side wall of the housing 7. The conveying unit 2 includes a conveyor belt 201, a limiting plate 202, a groove 205, and a gear 207. The limiting plate 202 is installed on the top of the conveyor belt 201, and the groove 205 is formed on the top surface of the limiting plate 202. The gear 207 meshes with the conveyor belt 201, and one end of the gear 207 is connected to the output end of a stepper motor through a rotating shaft. The stepper motor is installed on the side wall of the housing 7. The material bag is transported from the belt conveyor 1 to the conveyor belt 201. Since the limiting plate 202 is installed on the conveyor belt 201, it can support the material bag. At the same time, the cut granular material will fall into the groove 205 to collect the granular material and prevent the granular material from rolling randomly.

[0024] Please see Figure 1 In this embodiment, the cutting part 6 includes a cutting disc 601 and a motor. One end of the cutting disc 601 is movably mounted on the inner wall of the housing 7 via a rotating shaft. The rotating shaft on the cutting disc 601 passes through the side wall of the housing 7 and is connected to the output end of the motor. When the motor is started, the motor will drive the cutting disc 601 to rotate, thereby cutting the material package.

[0025] Please see Figure 1In this embodiment, the conveying unit 2 also includes a baffle 203. The baffle 203 is installed on the conveyor belt 201, and one side of the baffle 203 is fixedly connected to the end face of the limiting plate 202. The baffle 203 is located on the end face of the limiting plate 202 and works with the limiting plate 202 to block the granular material and prevent the granular material from rolling into the gap between the conveyor belt 201 and the housing 7.

[0026] Please see Figure 1 In this embodiment, there are several limiting plates 202, which are evenly arranged on the conveyor belt 201, and a gap is left between every two limiting plates 202.

[0027] Please see Figure 1 In this embodiment, the conveying unit 2 also includes a limiting block 204. The limiting block 204 is installed on the top surface of the limiting plate 202, and the cross-section of the limiting block 204 is designed as a triangle. The limiting block 204 installed on the limiting plate 202 can support the material bag. The limiting block 204 is designed as a triangular prism, and the edges of the limiting block 204 are used to enhance the friction between the limiting block 204 and the material bag, so as to prevent the material bag from moving backward under force during cutting.

[0028] Please see Figure 3 and Figure 4 In this embodiment, the conveying unit 2 also includes a partition 206, which is installed on the top surface of the conveyor belt 201, and the partition 206 and the limiting plate 202 are arranged at intervals.

[0029] The partition 206 and the limiting plate 202 can cooperate to block the falling granular material and prevent the granular material from rolling into the gap between the conveyor belt 201 and the housing 7.

[0030] Please see Figure 3 and Figure 4 In this embodiment, the bottom of the cutting disc 601 is inserted into the inner cavity of the groove 205, and the groove 205 is located in the middle of the limiting plate 202. The cutting edge of the cutting disc 601 enters the groove 205, which can ensure that the entire material package is completely cut off.

[0031] Please see Figure 3 and Figure 4 In this embodiment, the partition 206 is made of rubber, and both ends of the partition 206 are connected to the side wall of the baffle 203. At the same time, both ends of the partition 206 are designed to be pleated. By utilizing the stretchability of the pleats, the partition 206 can adapt to the curvature at both ends of the conveyor belt 201.

[0032] Please see Figure 4In this embodiment, one end of the conveyor belt 201 is connected to the belt conveyor 1, and the other end of the conveyor belt 201 is connected to the inlet of the rotary screen 3. The material package conveyed from the belt conveyor 1 can enter the conveyor belt 201 and then enter the rotary screen 3 to separate the material package from the material.

[0033] In practical use, the material package is first transported to the conveyor belt 201 via the belt conveyor 1, and then cut by the cutting disc 601 on the conveyor belt 201. The granular material falling from the material package will naturally fall into the groove 205. At the same time, some of the granular material will roll and be blocked by the limiting plate 202 and the partition plate 206 to prevent it from rolling into the gap between the conveyor belt 201 and the shell 7. Finally, it is transported together with the conveyor belt 201 to the rotary screen 3 for separation of the material from the material package.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
