Description

Technical Field

[0001] This utility model belongs to the technical field of transportation equipment, and specifically relates to an automatic cutting and transportation line for packaging bags. Background Technology

[0002] In the production process of protein powder at the manufacturing plant, bagged powder is transported from the outside to the clean space inside via a conveyor belt, and then poured into production drums for further processing. After the powder bag is sent to the end via the conveyor belt, the packaging bag must be cut open before the powder is poured into the production drum.

[0003] For a long time, this bag-breaking process has relied on manual labor at the end of the conveyor belt. However, manual bag breaking is not only cumbersome but also inefficient, making it difficult to meet the needs of large-scale production. Utility Model Content

[0004] This invention provides an automatic cutting and conveying line for packaging bags to solve the problem of low efficiency in discharging powder from bagged powder.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An automatic packaging bag cutting and conveying line includes a conveying line, the output end of which is provided with a bag material separation mechanism;

[0007] The transport line includes a tracked feeder and a metal ramp located at the tail end of the tracked feeder, with the discharge end of the metal ramp located above the bag separation mechanism.

[0008] The metal ramp is equipped with a cutting tool for cutting the cloth bag, and the bag separation mechanism includes a support grid for separating the bag body and the material body, and the support grid is smoothly connected to the metal ramp.

[0009] Furthermore, a support frame is fixed to the back side of the metal ramp, and the cutting tool is mounted on the support frame;

[0010] The slicing tool includes a drive source and a telescopic blade, the drive source being used to drive the telescopic blade to extend out of the metal ramp or retract the metal ramp.

[0011] Furthermore, the metal ramp discharge end is connected to a material collection funnel, and the support grid is disposed at the inlet of the material collection funnel.

[0012] A frame cover is provided above the material discharge hopper, and a suction channel is installed on the top of the frame cover.

[0013] Furthermore, the support grid includes a support area in the middle and material drop areas symmetrically arranged on both sides of the support area, and the material drop areas have a slope that gradually slopes downward toward the support area.

[0014] Furthermore, there is a gap between each of the material dropping areas and the support area, and the gap between the material dropping areas and the support area is the material dropping point;

[0015] The slicing cutter is provided in two sets, and the two sets of slicing cutters are respectively aligned with the two material drop points.

[0016] Furthermore, the support grid includes a number of spaced-apart grids, each of which is bent downwards with varying curvature.

[0017] Furthermore, the curvature of the grid gradually increases as the material dropping area moves closer to the support area;

[0018] The curvature of each grid bar gradually increases from the center outwards from both sides of the support area.

[0019] Furthermore, the discharge end of the metal ramp is spaced apart from the surface of the discharge hopper, and a vibration device for driving the support grid to vibrate is installed on the discharge hopper.

[0020] The present invention can achieve the following beneficial effects:

[0021] 1. This utility model sets a cutting tool on the metal ramp of the transport line and configures a support grid that is smoothly connected to the metal ramp at the output end of the transport line. The bag body is reserved above the support grid, and the powder falls below the support grid, realizing the integrated operation of bagged powder from conveying to automatic cutting and bag separation. This application replaces the traditional manual bag breaking method, eliminating the need for manual cutting of each bag, significantly improving the efficiency of bag breaking and powder separation, and meeting the needs of large-scale production.

[0022] 2. The cutting tool adopts a telescopic blade structure driven by a drive source, which can precisely control the timing of the blade extension and retraction, avoiding the problem of excessive debris caused by continuous contact with the packaging bag by traditional fixed blades; at the same time, the suction channel above the material hopper can promptly absorb the dust generated during the operation, reducing powder pollution and dust pollution in the workshop environment.

[0023] 3. The support grid, by setting grids with different curvatures, and the design of support and discharge areas, and in conjunction with the vibration equipment to drive the grid to vibrate, can not only provide stable support for the bag, but also promote the rapid passage of residual powder in the bag through the discharge point into the discharge funnel, effectively reducing the powder residue rate and improving the powder utilization rate.

[0030] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0031] like Figures 1 to 3 As shown, an automatic bag cutting and conveying line includes a conveyor line 1 and a bag material separation mechanism 2 disposed at the output end of the conveyor line 1. The conveyor line 1 includes a crawler feeder 11 and a metal ramp 12, wherein the crawler feeder 11 is used to transport bagged powder from the outside to the production area, and the metal ramp 12 is fixed to the tail end of the crawler feeder 11, with its discharge end extending above the bag material separation mechanism 2 to ensure that the bagged powder can smoothly transition from the crawler feeder 11 to the metal ramp 12.

[0032] To achieve automatic tearing of packaging bags, a cutting blade 3 is installed on the metal ramp 12. A support frame is fixed to the back side of the metal ramp 12, and the cutting blade 3 is mounted on the support frame. The cutting blade 3 includes a drive source 31 and a telescopic blade 32. The drive source 31 can be a cylinder or a motor. The drive source 31 drives the telescopic blade 32 to extend or retract along the surface of the metal ramp 12. When the bagged powder is conveyed to the corresponding position on the metal ramp 12, the telescopic blade 32 extends and tears the packaging bag. After the packaging bag is conveyed, it retracts to avoid unnecessary danger.

[0033] The bag separation mechanism 2 is used to separate the bag body from the material body. It includes a support grid 21 and a discharge hopper 4. The support grid 21 is set at the inlet of the discharge hopper 4 and is smoothly connected to the discharge end of the metal ramp 12, so that the cut bagged powder can slide smoothly into the support grid 21. After being screened by the support grid 21, the bag body remains on the support grid 21, and the powder falls into the discharge hopper 4 for collection.

[0034] Specifically, the support grid 21 includes a support area 22 in the middle and material drop areas 23 symmetrically arranged on both sides of the support area 22. The material drop areas 23 gradually slope downwards towards the support area 22, forming a certain slope. There is a gap between each material drop area 23 and the support area 22, which is the material drop point 24. Two sets of cutting blades 3 are correspondingly arranged, and the two sets of cutting blades 3 are aligned with the two material drop points 24 respectively, so that the cut position of the bagged powder is directly opposite the material drop point 24. When the bagged powder is cut by the cutting blades 3 at the corresponding position, it slides onto the support grid 21. Since the cut point and the material drop point 24 correspond, and the material drop area 23 has a slope towards the support area 22, the material drop area 23 tends to cause the material in the packaging bag to accumulate towards the material drop point 24. At the same time, the support area 22 can support the bag to prevent the bag from falling from the material drop point 24.

[0035] Furthermore, the support grid 21 includes several spaced grids 211, each grid 211 curving downwards with varying curvatures. In the material drop area 23, the curvature of the grids 211 gradually increases towards the support area 22. Similarly, in the support area 22, the curvature of each grid 211 gradually increases from the center outwards. Because the support area 22 has a slope from the center outwards, the bagged powder located in the support area 22 can be supported by the grid with the smaller curvature in the center, thus limiting the bag's fall through the gaps in the support grid 21. The remaining area of ​​the bagged powder is unloaded from the drop point 24 by the slopes on both sides of the support area 22 and by the slopes in the drop area 23. The design of the support grid 21 in this application guides the bag to be stably placed on the support grid 21 while also promoting the accumulation of powder towards the drop point 24.

[0036] In addition, the discharge end of the metal ramp 12 is spaced apart from the surface of the discharge hopper 4. A vibrating device, which can be a vibrating motor, is installed on the discharge hopper 4. When it is working, it can drive the support grid 21 to vibrate, further causing the powder remaining in the bag to enter the discharge hopper 4 through the discharge point 24, thus reducing powder residue. In actual use, when the device of this application separates the bag and the powder, the amount of powder residue is small. In addition, when a worker stands nearby to pick up the bag, if there is still powder remaining in some of the bag, the worker can manually remove the powder.

[0037] Furthermore, a frame cover 41 is provided above the material discharge hopper 4, and a suction channel 42 is installed on the top of the frame cover 41. The suction channel 42 can be connected to an external negative pressure device, and the dust generated during the falling of the powder can be removed in time through the suction channel 42.

[0038] In operation, the automatic bag cutting and conveying line of this application transports bagged powder to a metal ramp 12 via a crawler feeder 11. The powder then slides down the ramp to the cutting blade 3, where a drive source 31 drives a telescopic blade 32 to extend and cut the bagged powder. The cut bag and powder continue to slide down to a support grid 21. Under the support of the grid 21 and the vibration of the vibrating device, the powder falls from the cutting point and drop point 24 into the discharge funnel 4 for collection, while the empty bag remains on the grid 21, thus separating the bag from the powder. The dust generated during the process is removed through a suction channel 42, ensuring a clean working environment.

[0039] 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.
