Description

Technical Field

[0001] This utility model belongs to the field of feed production technology, and in particular relates to an automatic bagging device. Background Technology

[0002] In the production process of feed mills, the raw material feeding stage is an important part of the production process. The traditional feeding method mainly relies on manual operation. Bagged raw materials are usually transported to the feed mill by transport vehicles. Workers unload the bagged raw materials and stack them on iron pallets. After the stacking is completed, a forklift moves the whole stack of bagged raw materials to the feeding port next to the raw material warehouse. The feeding workers use a knife to cut open the bagged material, and then manually tilt and shake the raw material bags to put the raw materials into the feeding port. Then the workers clean up the cut waste bags.

[0003] Since bagged raw materials are usually heavy, the feeding operator needs to lift and shake the bag to fully insert the raw materials into the feeding port. When production needs are large, this is a very heavy workload for the feeding operator, which not only requires high labor costs but also results in low production efficiency. This makes it difficult to meet the needs of large-scale production in modern feed mills and is not conducive to the profitable development of enterprises. Therefore, we propose this automatic bag cutting equipment to solve the above problems. Summary of the Invention

The output direction of the conveying part faces the outlet, and the other side of the outlet is connected to the input port of the pallet storage mechanism.

[0014] By adopting the above technical solution, the iron pallet is prevented from falling off during the deflection process.

[0015] Furthermore, the pallet storage mechanism includes a mounting bracket, a scissor lift assembly, an elastic positioning assembly, and a fourth conveying assembly. The scissor lift assembly is mounted on the mounting bracket, the fourth conveying assembly is connected to the outlet and mounted on the scissor lift assembly, and there are at least two sets of elastic positioning assemblies arranged opposite to each other, with the elastic positioning assemblies located above the fourth conveying assembly.

[0039] like Figure 1 and Figure 2As shown, the specific solution of the embodiment is as follows: An automatic bag cutting device includes a raw material conveying mechanism 1. The conveying end of the raw material conveying mechanism 1 is provided with an L-shaped fixed frame 3. An L-shaped flipping and destacking mechanism 2 is rotatably installed on the top of the vertical surface of the L-shaped fixed frame 3. A driving component for driving the L-shaped flipping and destacking mechanism 2 to flip is installed on the L-shaped fixed frame 3. The L-shaped flipping and destacking mechanism 2 includes a conveying structure set on the bottom surface and a third conveying component set on the vertical surface. The raw material conveying mechanism 1 is located on one side of the bottom surface of the L-shaped fixed frame 3. A feeding conveyor belt 4 is also provided on the side of the vertical surface of the L-shaped fixed frame 3 away from the L-shaped flipping and destacking mechanism 2. The feeding conveyor belt 4 is connected to the third conveying component. A bag breaking mechanism 5 is provided at the conveying end of the feeding conveyor belt 4. A drum screen 6 is provided at the discharge end of the bag breaking mechanism 5. A screw conveyor 7 is provided at the discharge end of the drum screen 6. A scraper conveyor 8 is provided below the drum screen 6. A tray storage mechanism 9 is also provided on the side of the L-shaped flipping and destacking mechanism 2.

[0040] The drive component is preferably a hydraulic cylinder, which lifts the L-shaped flipping and destacking mechanism 2 so that it can flip.

[0041] In addition, the raw material conveying mechanism 1 and the feeding conveyor belt 4 are both used for conveying bagged stacked materials;

[0042] The L-shaped flipping and depalletizing mechanism 2 is used to lift the bagged stacked material, making it easier to transfer the bagged stacked material to the feeding conveyor belt 4, thereby facilitating the subsequent bag breaking and feeding work;

[0043] Bag-breaking mechanism 5 is used to break bags;

[0044] The rotary screen 6 is used to separate broken bags from bulk materials;

[0045] Screw conveyor 7 is used to transport broken bags for easy subsequent collection and cleaning;

[0046] The scraper conveyor 8 is used for feeding bulk materials;

[0047] Pallet storage mechanism 9 is used for recycling iron pallets.

[0048] like Figure 3 As shown, in this embodiment, the conveying structure includes a first conveying component 12, a fixing component 14, and a second conveying component 13. The input end of the first conveying component 12 is connected to the conveying end of the raw material conveying mechanism 1. The fixing component 14 is located on the first conveying component 12, and the second conveying component 13 is located on one side of the first conveying component 12. The conveying direction of the second conveying component 13 is towards the pallet storage mechanism 9. The fixing component 14 includes two cylinders 1401 disposed on the bottom surface of the L-shaped flipping and destacking mechanism 2 and disposed opposite to each other. The output end of the cylinders 1401 is provided with a limiting block 1402. There are at least two sets of fixing components 14.

[0049] The first conveying component 12, the fixing component 14, and the second conveying component 13 are all bolted to the bottom surface of the L-shaped flipping and destacking mechanism 2, and the third conveying component is bolted to the vertical surface of the L-shaped flipping and destacking mechanism 2. The second conveying component 13 and the third conveying component are preferably chain conveyors, the first conveying component 12 is preferably a roller conveyor belt, and the second conveying component 13 is located in the middle of the two roller belts. The first conveying component 12, the second conveying component 13, and the third conveying component mainly play the role of conveying.

[0050] In addition, the limiting block 1402 is located between the rollers of the first conveying assembly 12. The limiting block 1402 is driven by the cylinder 1401 to move closer to the iron pallet, so as to clamp and fix the iron pallet. By fixing the iron pallet, the iron pallet is not easy to move at the same time when the bagged stacked material is transferred to the feeding conveyor belt 4, thereby facilitating the subsequent recycling work.

[0051] Please see Figure 3 In this embodiment, the second conveying component 13 includes a lifting part and a conveying part disposed on the bottom surface of the L-shaped flipping and destacking mechanism 2. The lifting part is located between the first conveying components 12, and the conveying part is disposed at the output end of the lifting part. Both sides of the L-shaped flipping and destacking mechanism 2 are provided with a cover plate 11. The bottom surface of the cover plate 11 is provided with an outlet. The output direction of the conveying part is towards the outlet, and the other side of the outlet is connected to the input port of the pallet storage mechanism 9.

[0052] The mask 11 is designed to prevent bagged stacked material from falling to the outside of the L-shaped flipping and destacking mechanism 2 when it is flipped.

[0053] The L-shaped flipping and destacking mechanism 2 is connected to the pallet storage mechanism 9 via the outlet, and the iron pallet is transferred to the pallet storage mechanism 9 via the conveying unit.

[0054] It is worth noting that since the bottom of the iron pallet is located on the first conveying assembly 12, the iron pallet is lifted by the lifting part and then conveyed by the conveying part. The lifting part is preferably a hydraulic rod, and the conveying part is preferably a chain conveyor.

[0055] Please see Figure 4 In this embodiment, the pallet storage mechanism 9 includes a mounting bracket, a scissor lift assembly 16, an elastic positioning assembly 17, and a fourth conveying assembly 15. The scissor lift assembly 16 is mounted on the mounting bracket, and the fourth conveying assembly 15 is connected to the outlet and mounted on the scissor lift assembly 16.

[0056] The fourth conveying assembly 15 is used to receive the iron pallet conveyed to the inside of the pallet storage mechanism 9 by the conveying section, and it is preferably a chain conveyor.

[0057] The scissor lift assembly 16 is used to lift the iron pallet so that it is positioned on the elastic positioning assembly 17, which is preferably a scissor lift machine;

[0058] The elastic positioning component 17 is used to secure the iron pallet.

[0059] like Figure 5 As shown, there are at least two sets of elastic positioning components 17 arranged opposite to each other. The elastic positioning components 17 are located above the fourth conveying component 15. The elastic positioning components 17 include a fixing rod 1702 arranged on the mounting bracket. A limit cover 1701 is sleeved on the outer wall of the fixing rod 1702. The side of the limit cover 1701 away from the fixing rod 1702 is set with an incline. The inner wall of the limit cover 1701 is provided with an elastic reset member 1703 that abuts against the fixing rod 1702.

[0060] Specifically: The elastic reset component 1703 includes a positioning block installed on the inner wall of the limiting cover 1701. A positioning rod is welded between the inner wall of the limiting cover 1701 away from the positioning block and the positioning block. The positioning rod passes through the fixing rod 1702 and is slidably connected to the inner wall of the fixing rod 1702. A reset spring is fixedly installed between the fixing rod 1702 and the positioning block. The spring is sleeved on the outside of the positioning rod. The iron pallet moves upward under the action of the scissor lift assembly 16. When the top surface of the iron pallet contacts the inclined surface of the limiting cover 1701, the limiting cover 1701 will move away from the iron pallet. At this time, the reset spring is in a compressed state. When the iron pallet moves above the limiting cover 1701, the limiting cover 1701 will reset under the elastic force of the reset spring, thereby positioning the iron pallet, which is convenient for subsequent workers to collect the accumulated iron pallets.

[0061] In this embodiment, the bag breaking mechanism 5 includes a box and a crushing roller disposed inside it. The conveying end of the feeding conveyor belt 4 is connected to the feed port of the box, the feed end of the drum screen 6 is connected to the discharge port of the box, the drum screen 6 is also equipped with a pulse dust collector 10, and the output end of the scraper conveyor 8 is also connected to a tee, the other two ports of the tee are connected to chutes.

[0062] Among them, the bag breaking mechanism 5 can cut the outer packaging bag of the bagged stacked material, thereby separating the waste bag from the bulk material. The scraper conveyor 8 is used to transport the bulk material and complete the feeding work. The bottom surface of the drum screen 6 is provided with a discharge port for the discharge of bulk material. After the bulk material is discharged through the discharge port, it will fall onto the scraper conveyor 8, thereby completing the feeding work of bulk material. Through the three-way matching pipe, the bulk material can be transported to different feeding ports to complete the feeding in multiple directions.

[0063] In addition, by installing a pulse dust collector 10 on the drum screen 6, the dust generated during the breaking and conveying of feed raw materials can be absorbed, which not only improves the stability of the working environment, but also reduces the dust concentration and avoids the health impact on workers due to excessive dust concentration.

[0064] like Figure 6 , Figure 7 and Figure 8 As shown, the working method of the above embodiment is as follows: the bagged stacked material is placed on an iron pallet, and then transferred to the raw material conveying mechanism 1 by a forklift. The raw material conveying mechanism 1 can convey the bagged stacked material to the first conveying component 12 on the bottom surface of the L-shaped flipping and destabilizing mechanism 2. Then, the cylinder 1401 drives the limiting block 1402 to move closer to the iron pallet to clamp and fix the bottom of the iron pallet. The driving component drives the L-shaped flipping and destabilizing mechanism 2 to flip upward until the second conveying component 13 and the feeding conveyor belt 4 are at the same level. At this time, the bagged stacked material will flip onto the second conveying component 13 and move to the feeding conveyor belt 4 under the push of the second conveying component 13. Then it will fall into the bag breaking mechanism 5. The bag breaking mechanism 5 will cut the bag on the outer surface of the bagged stacked material into waste bags and loose material, which will enter the drum screen 6 together. Under the action of the drum screen 6, the loose material will fall onto the scraper below the drum screen 6. Feeding is performed on the plate conveyor 8, while waste bags are fed into the screw conveyor 7 through the discharge end under the action of the drum screen 6 for separate recycling. When the drive component drives the L-shaped flipping and destacking mechanism 2 to reset, the cylinder 1401 drives the limit block 1402 to move away from the iron pallet, thus releasing the iron pallet from its fixation. The iron pallet is lifted by the lifting part, causing it to leave the first conveying component 12. At this time, under the action of the conveying part, the iron pallet enters the fourth conveying component 15 in the pallet storage mechanism 9 through the outlet. The scissor lifting component 16 can lift the iron pallet and lock it into the elastic positioning component 17, thereby completing the recycling of the iron pallet. This device can effectively replace manual labor in feeding, breaking bags, and conveying feed raw materials, significantly reducing the high-intensity labor of manually lifting and cutting bags, improving work efficiency, reducing labor costs, and improving enterprise benefits.
