Description

Technical Field

[0001] This utility model belongs to the technical field of unpacking equipment, specifically relating to a high-efficiency material conveying component for an unpacking machine. Background Technology

[0002] Packaging unpacking machines are widely used in industries such as chemical, pharmaceutical, food, and building materials that require the processing of bagged powdery materials.

[0003] There are two main types of material conveying methods used in existing unpacking machines: belt / chain conveyor and hanging conveyor.

[0004] Among them, belt / chain conveyor mechanisms mainly transport materials via conveyor belts or chains. In the corresponding unpacking machines, saw blades are installed on the upper or lower side of the conveyor mechanism. The belt / chain conveyor mechanism drives the material through the saw blades, cutting several openings in the material bag along the conveying direction. Then, the material is unloaded by its own weight. However, for lightweight materials and multi-layered bags, on the one hand, it is difficult to completely cut open the multiple layers of the bag; on the other hand, the material is relatively light, and cutting only a few openings along the conveying direction makes it difficult for the material to fall out completely.

[0005] Therefore, in order to completely cut open multi-layered bags and allow the material to fall freely under its own weight, some companies or manufacturers use suspended conveyor mechanisms to transport materials. These mechanisms mainly consist of a track and a gripping mechanism that reciprocates along the track. In the corresponding unpacking machine, a cutting blade is installed under the grippers. This blade is X-shaped in the plane and conical in the vertical direction. During unpacking, the gripping mechanism grabs the material and moves it along the track to the underside of the cutting blade. Then, the gripping mechanism moves downwards or the cutting blade moves upwards, cutting open the multi-layered bag and leaving an X-shaped opening, allowing the lightweight material to fall freely.

[0006] However, the conveying efficiency of suspended conveyor systems is relatively low. Utility Model Content

[0007] This invention provides a high-efficiency material conveying component for a packaging unpacking machine, aiming to solve the technical problem of low efficiency in conveying lightweight materials in existing packaging unpacking machine conveying components.

[0013] In one possible implementation of the high-efficiency material conveying component for unpacking machine provided by this utility model, spikes are fixed on the outer side of the conveying chain.

A barbed hook assembly, comprising multiple barbed hooks, wherein the multiple barbed hooks are spaced apart along the axis of the second rotating shaft; The third drive assembly is connected to the tilting frame, and its power output end is connected to the second rotating shaft. In this case, the opening directions of the barbs in the two gripping mechanisms are opposite, and they rotate about the second rotating axis in opposite directions or towards each other.

[0016] In one possible implementation of the high-efficiency material conveying component for the unpacking machine provided by this utility model, the barbed hook group includes a plurality of long barbed hooks and a plurality of short barbed hooks, and the long barbed hooks and the short barbed hooks are alternately spaced along the second rotating shaft axis.

[0027] During the research on the existing unpacking machine's lifting conveyor mechanism, the applicant discovered that the next bag of material can only be lifted for unpacking after the previous bag has been unpacked and the gripping mechanism has been reset. In other words, one complete stroke of the gripping mechanism can only complete one unpacking operation, resulting in low unpacking efficiency.

[0028] Please refer to the following: Figures 1 to 8 The high-efficiency material conveying component for a packaging unpacking machine provided by this utility model is described below. The high-efficiency material conveying component for a packaging unpacking machine includes a first rotating shaft 12, a tilting frame 21, a first drive assembly 11, and two conveying and gripping assemblies. The first rotating shaft 12 is used to rotate in conjunction with the casing 51 of the packaging unpacking machine. The tilting frame 21 is connected to the first rotating shaft 12, with the upper side of the tilting frame 21 serving as the packaging unpacking station and the lower side as the unloading station. The power output end of the first drive assembly 11 is connected to the first rotating shaft 12 to drive the first rotating shaft 12 and the tilting frame 21 to rotate. The two conveying and gripping assemblies are respectively located on both sides of the tilting frame 21 to alternately convey and grip material bags. Each conveying and gripping assembly includes a conveying component and a gripping component, which are located on one side of the tilting frame 21 and connected to it. The conveying component is used to transport material bags, and the gripping component is used to grip and release material bags. The tilting frame 21 rotates 180 degrees each time, alternately placing the two conveying and gripping assemblies at the packaging unpacking station and the unloading station.

[0029] Specifically, the first drive assembly 11 is a device such as a motor, a rotary cylinder 45, or a rotary hydraulic cylinder that can drive the first rotating shaft 12 to rotate 180 degrees, and the first drive assembly 11 is located on the outside of the housing 51 and connected to the housing 51.

[0030] The high-efficiency material conveying component for unpacking machines provided by this utility model is mainly designed for lightweight materials such as toner.

[0031] It should be noted that, as Figure 8 As shown in the embodiment of this utility model, in the unpacking machine corresponding to the high-efficiency material conveying component for unpacking machine, the cutting component 52 is located on the upper side of the tilting frame 21 and can move up and down, and the hopper 53 is located on the lower side of the tilting frame 21. After the conveying component on the upper side of the tilting frame 21 conveys the material bag to the lower side of the cutting component 52, the gripping component grips the material bag, the cutting component 52 moves down and cuts the material bag. Then, the first driving component 11 drives the tilting frame 21 to rotate 180 degrees so that the cut material bag faces down and the material is unloaded by its own weight. At the same time, the conveying and gripping component that has moved from the lower side to the upper side continues to work, conveying the empty material bag down and conveying and gripping the next material bag, and so on in a reciprocating cycle.

[0032] In actual operation, material bags are transported to the conveying and gripping components through belt conveyors, push plate conveyors, etc.

[0033] The beneficial effects of the high-efficiency material conveying component for unpacking machine provided in this embodiment of the present invention are as follows: Compared with the prior art, the high-efficiency material conveying component for unpacking machine provided in this embodiment of the present invention has conveying and gripping components set on both sides of the flipping frame 21, and the flipping frame 21 is driven to flip by the first driving component 11, so that the two conveying and gripping components are alternately placed at the unpacking station and the unloading station. Thus, while the lower conveying and gripping component grips the material bag for unloading, the upper conveying and gripping component continues to convey and grip the material bag for unpacking, thereby effectively improving the conveying efficiency of lightweight materials.

[0034] like Figure 6 and Figure 7 As shown in the embodiment of the high-efficiency material conveying assembly for the unpacking machine provided in this utility model, the conveying assembly includes a second drive assembly 31, a drive wheel 32, a driven wheel 33, and a conveying component. The second drive assembly 31 is connected to the tilting frame 21; the drive wheel 32 is connected to the power output end of the second drive assembly 31; the driven wheel 33 is spaced apart from the drive wheel 32 along the conveying direction and rotates in cooperation with the tilting frame 21; the conveying component is sleeved on the drive wheel 32 and the driven wheel 33 to drive the material bag to move.

[0035] Specifically, the second drive assembly 31 is an existing assembly of a motor and a reducer, with an output shaft on the reducer, and the drive wheel 32 is connected to the output shaft for transmission. The second drive assembly 31 can also be a stepper motor or a servo motor.

[0036] like Figure 2 and Figure 7 As shown, in a specific embodiment of the high-efficiency material conveying component for unpacking machine provided in this utility model embodiment, a first sealing box 23 is fixed on the flipping frame 21, and a second drive component 31 is disposed inside the first sealing box 23.

[0037] Specifically, the first sealing box 23 is rectangular and is formed by splicing multiple plates. Installing the second drive assembly 31 inside the first sealing box 23 can effectively prevent external dust from entering the second drive assembly 31 and ensure its service life.

[0038] like Figure 6 and Figure 7 As shown in the embodiment of the high-efficiency material conveying component for unpacking machine provided in this utility model, the conveying component is a conveying chain 34, and the driving wheel 32 and the driven wheel 33 are both sprockets.

[0039] It should be noted that the conveyor chain 34 is a roller chain, which consists of an inner chain plate, an outer chain plate, a pin 3, a bushing, and rollers. The inner chain plate and bushing, and the outer chain plate and pin, are interference fits; the rollers and bushing, and the bushing and pin, are clearance fits. During operation, the inner and outer chain links can flex relative to each other, the bushing can rotate freely around the pin, and the rollers, fitted onto the bushing, reduce wear between the chain and the sprocket. To reduce weight and ensure equal strength across all sections, the inner and outer chain plates are often made in a figure-eight shape. All chain components are made of carbon steel or alloy steel. They are typically heat-treated to achieve a certain strength and hardness.

[0040] Specifically, such as Figure 1 and Figure 2 As shown in the embodiment of the high-efficiency material conveying component for unpacking machine provided in this utility model, there are several conveying chains 34, which are spaced apart and arranged in parallel perpendicular to the conveying direction. The driving wheel 32 and the driven wheel 33 correspond one-to-one with the conveying chain 34.

[0041] More specifically, there are two conveyor chains 34, which are respectively located on both sides of the first sealing box 23, and the second drive assembly 31 has two power output ends, which are respectively connected to two drive wheels 32.

[0042] like Figure 1 and Figure 7 As shown in the embodiment of the high-efficiency material conveying component for unpacking machine provided in this utility model, spikes 341 are fixed on the outer side of the conveying chain 34 to pierce the material bag, so as to increase the interaction force between the chain and the material bag and drive the material bag to move more stably.

[0043] Specifically, the length of the chain is represented by the number of links, generally an even number of links are selected, each link is provided with a spike 341, or a spike 341 is provided every few links, and the number of intervals is set according to actual needs.

[0044] like Figure 1 and Figure 2 As shown in the embodiment of the high-efficiency material conveying component for unpacking machine provided in this utility model, the flipping frame 21 is provided with receiving plates 22 on both sides. The receiving plates 22 are fixedly connected to the flipping frame 21 and are used to receive material bags. The spikes 341 protrude from the receiving plates 22.

[0045] Specifically, the receiving plate 22 is used to support the weight of the material bag, and the material bag conveying chain 34 slides on the receiving plate 22.

[0046] like Figure 3 and Figure 5As shown in the embodiment of the high-efficiency material conveying component for unpacking machine provided in this utility model, the gripping component includes two gripping mechanisms, which are spaced apart and arranged in parallel in the vertical conveying direction.

[0047] The gripping mechanism includes a second rotating shaft 41, a barbed hook assembly, and a third drive assembly. The axis of the second rotating shaft 41 is parallel to the conveying direction, and the second rotating shaft 41 is rotatably engaged with the tilting frame 21. The barbed hook assembly includes multiple barbed hooks, which are spaced apart along the axis of the second rotating shaft 41. The third drive assembly is connected to the tilting frame 21, and its power output end is connected to the second rotating shaft 41.

[0048] The two gripping mechanisms have hooks with opposite opening directions and rotate around the second pivot 41 in opposite directions or towards each other.

[0049] like Figure 4 and Figure 5 As shown, the third drive assembly includes a rocker arm 44 and a cylinder 45. One end of the rocker arm 44 is fixedly connected to the second rotating shaft 41; one end of the cylinder 45 is rotatably connected to the tilting frame 21, and the other end is rotatably connected to the other end of the rocker arm 44.

[0050] Cylinder 45 can be replaced by a hydraulic cylinder, electric actuator, etc.

[0051] The third drive component can also be a motor, a rotary cylinder 45, or a rotary hydraulic cylinder, etc.

[0052] It should be noted that when the conveyor chain 34 transports the material bag to the required position (below the cutting component 52 in the unpacking machine), the third drive component drives the two second rotating shafts 41 and their barbs to rotate in opposite directions. The barbs extend out of the receiving plate 22 and pierce into the material bag, gripping and releasing it. After unloading and flipping back to the top, the third drive component drives the two second rotating shafts 41 and their barbs to rotate in opposite directions. The barbs retract into the underside of the receiving plate 22, releasing the material bag. The material bag continues to be transported forward by the conveyor chain 34 and falls into the bag discharge bin 54 at the tail end, exiting the unpacking machine.

[0053] like Figure 3 and Figure 7 As shown, in a specific embodiment of the high-efficiency material conveying component for unpacking machine provided in this utility model, the barbed hook group includes a plurality of long barbed hooks 42 and a plurality of short barbed hooks 43, and the long barbed hooks 42 and short barbed hooks 43 are alternately spaced along the axis of the second rotating shaft 41.

[0054] It should be noted that the high-efficiency material conveying component for unpacking machine provided in this embodiment of the utility model is mainly for material bags with multiple layers. The barbs are divided into several long barbs 42 and several short barbs 43. When piercing the material bag, on the one hand, the number of barbs in contact with the material bag at the same time is reduced, and the pressure at the contact point is increased, making it easier for the long barbs 42 to pierce into the material bag. On the other hand, the long barbs 42 pierce into and grip the material bag first, which can provide sufficient resistance for the piercing of the short barbs 43, so that the short barbs 43 can fully pierce and penetrate the multi-layered material bag.

[0055] like Figure 2 and Figure 3 As shown, in a specific embodiment of the high-efficiency material conveying component for unpacking machine provided in this utility model, a second sealing box 24 is fixed on the flipping frame 21, and a third driving component is disposed inside the second sealing box 24.

[0056] The second sealing box 24 is rectangular and is formed by splicing multiple plates. There are two second sealing boxes 24 respectively located at both ends of the flipping frame 21. Installing the third drive component inside the second sealing box 24 can effectively prevent external dust from entering the third drive component and ensure its service life.

[0057] 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
