Description

Technical Field

[0001] This utility model relates to the technical field of packaging equipment, and in particular to a vertical vacuum packaging machine. Background Technology

[0002] In the chemical production field, many powdery, granular, or lumpy raw materials need to be vacuum-packed to isolate them from air and moisture, ensuring the stability of the products during transportation and storage.

[0003] Currently, the mainstream vertical vacuum packaging machines on the market can vacuum package chemical raw materials. During the vacuum packaging process, the operator places the raw material package filled with raw materials on the vacuum packaging work platform. Then, the opening of the raw material package is connected to the vacuum tube of the vacuum packaging machine. The vacuum packaging machine performs vacuuming and sealing operations in sequence. Finally, the operator unloads the sealed raw material package from the work platform.

[0004] However, due to the weight of the chemical raw material packages, operators need to repeatedly lift the empty bags to the vacuum packaging station at the top of the equipment and manually remove the finished packages after vacuum sealing. The weight of each handling can reach tens of kilograms, resulting in high labor intensity for workers. At the same time, the speed of manual handling is limited and it is difficult to match the theoretical packaging efficiency of the equipment, leading to a waste of the entire production line capacity.

[0026] A vertical vacuum packaging machine according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0027] Reference Figure 1 The present invention aims to provide an embodiment of a vertical vacuum packaging machine.

[0028] A vertical vacuum packaging machine according to an embodiment of this utility model, referring to... Figure 1 , Figure 4 and Figure 5 It includes a conveying mechanism and a vacuum packaging mechanism. The conveying mechanism includes a conveyor belt 100 and a first motor 110 that drives the conveyor belt 100 to rotate. The conveyor belt 100 is used to convey unsealed raw material packages. The vacuum packaging mechanism includes a vacuuming component and a sealing component. The vacuuming component is used to vacuum the raw material packages, and the sealing component is used to seal the opening of the raw material packages.

[0029] Understandably, this utility model, by setting up a conveying mechanism and a vacuum packaging mechanism, uses a filling machine to fill raw materials into bags, and the conveying mechanism uses a conveyor belt 100 to transport unsealed raw material bags to the vacuum packaging station. The operator arranges the opening of the raw material bag so that the opening of the raw material bag is connected to the vacuum assembly. The vacuum assembly is used to evacuate the raw material bag. Then, the sealing assembly seals the opening of the raw material bag. There is no need to manually lift the raw material bag, which greatly reduces the labor intensity of workers and improves the automation level of the equipment.

[0030] A vertical vacuum packaging machine according to an embodiment of the present invention further includes a flipping mechanism and a receiving mechanism. The flipping mechanism includes a flipping frame 120, rollers 130 arranged side by side on the flipping frame 120, and a power component that drives the flipping frame 120 to rotate. The flipping frame 120 is located below the vacuum assembly and can be arranged horizontally or inclined. The rollers 130 are arranged at the discharge end of the conveyor belt 100. When the flipping frame 120 is in a horizontal state, the rollers 130 can receive raw material packages from the conveyor belt 100. When the flipping frame 120 is in a horizontal state, the rollers 130 can unload the raw material packages. The receiving mechanism includes a conveying roller 140 and a second motor 150 that drives the conveying roller 140 to rotate. The conveying roller 140 is located below the roller 130 and is used to convey the sealed raw material packages.

[0031] Understandably, this utility model, by setting up a tilting frame 120, a roller 130, and a power component, uses the power component to drive the tilting frame 120 to rotate, so that the tilting frame 120 is in a horizontal state. The raw material package on the conveyor belt 100 can enter above the roller 130. The raw material package moves on the roller 130, greatly reducing the resistance received by the raw material package, so that the raw material package can move to the vacuum packaging position. After the raw material is vacuum packaged, the tilting frame 120 rotates at a certain angle, so that the tilting frame 120 is in an inclined state. Under the action of gravity, the raw material package slides down freely. The roller 130 rolls and conveys the raw material package. The conveyor roller 140 can receive the raw material package and transport it to the next process. Thus, there is no need for manual unloading of the raw material package, which greatly reduces the labor intensity of workers, improves the automation level of the equipment, and greatly improves the vacuum packaging efficiency.

[0032] In some embodiments of this utility model, guide plates 250 are provided on both horizontal sides of the conveyor belt 100. The guide plates 250 are used to limit the position of the raw material package to prevent the raw material package from deviating from the conveyor belt 100.

[0033] Understandably, the guide plate 250 constrains the movement trajectory of the raw material package on the conveyor belt 100, preventing it from deviating, getting stuck, or even falling off during the conveying process due to inertia or unstable center of gravity, and ensuring that each raw material package can accurately reach the discharge end of the conveyor belt 100 and be received by the flipping mechanism.

[0034] In some embodiments of this utility model, reference is made to Figure 3 A photoelectric proximity switch 240 is installed on one side of the discharge end of the conveyor belt 100. The photoelectric proximity switch 240 is used to detect the position of the raw material package.

[0035] Understandably, the photoelectric proximity switch 240 can detect in real time whether the raw material package has reached the predetermined position at the discharge end of the conveyor belt 100, providing an accurate signal to trigger the flipping mechanism and ensuring that the flipping frame 120 is in a horizontal state to receive the raw material package.

[0036] In some embodiments of this utility model, the vacuum assembly includes a vacuum tube 260 and a third cylinder 270 that drives the vacuum tube 260 to rise and fall. The vacuum tube 260 is used to insert into the opening of the raw material package.

[0037] Understandably, the third cylinder 270 drives the vacuum tube 260 to automatically and quickly rise and fall, ensuring the consistency of the depth and position of the vacuum tube 260 when it is inserted into the raw material package each time. Under the action of the vacuum pump, the vacuum tube 260 evacuates the raw material package, thus achieving the function of vacuum packaging.

[0038] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2The vacuum packaging mechanism also includes a clamping assembly, which includes a first clamping plate 280, a second clamping plate 290, and a fourth cylinder 300 that drives the second clamping plate 290 to move horizontally. The second clamping plate 290 and the first clamping plate 280 clamp the opening of the raw material package relative to each other. An avoidance groove is provided between the second clamping plate 290 and the first clamping plate 280 to avoid the vacuum tube 260.

[0039] Before vacuuming, the fourth cylinder 300 drives the second clamping plate 290 to move horizontally, so that the first clamping plate 280 and the second clamping plate 290 firmly clamp the opening area of ​​the raw material package to form a sealed cavity. This prevents air from seeping in from the opening during vacuuming, ensuring the vacuum level inside the raw material package. In addition, the clearance groove avoids the air extraction tube 260, preventing the second clamping plate 290 and the first clamping plate 280 from failing to clamp the opening of the raw material package.

[0040] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 The sealing assembly includes a first sealing strip 310 and a second sealing strip 320 located below the clamping assembly, and a fifth cylinder 330 that moves the second sealing strip 320. The first sealing strip 310 and the second sealing strip 320 clamp the opening of the raw material package to heat seal the opening of the raw material package.

[0041] It should be noted that both the first sealing strip 310 and the second sealing strip 320 are equipped with heating wires.

[0042] Understandably, the fifth cylinder 330 drives the second sealing strip 320 to move, so that the first sealing strip 310 and the second sealing strip 320 clamp the opening of the raw material package. Under the heating action of the heating wire, the opening of the vacuum-sealed raw material package is automatically heat-sealed, thereby ensuring a firm seal and good airtightness.

[0043] In some embodiments of this utility model, the flipping mechanism includes a bracket with two side plates 160 and a rotating shaft 170 disposed between the two side plates 160. The two side plates 160 are respectively located on opposite sides of the conveyor belt 100, and the flipping frame 120 is mounted on the rotating shaft 170.

[0044] Understandably, the bracket formed by the two side plates 160 provides a rigid and stable support structure for the tilting frame 120 and the rotating shaft 170, ensuring that the tilting action is smooth and reliable, and is especially suitable for bearing heavy chemical raw material packages.

[0045] In some embodiments of this utility model, the power component is a first cylinder 190, a connecting rod 180 is provided on a side plate 160, a suspension rod 200 is provided at the end of the rotating shaft 170, one end of the cylinder is hinged to the connecting rod 180, and the other end of the cylinder is hinged to the suspension rod 200.

[0046] It is understandable that the first cylinder 190 is used as the power component, and the first cylinder 190 is hinged to the connecting rod 180 and the suspension rod 200. The first cylinder 190, the side plate 160 and the tilting frame 120 form a linkage mechanism to provide the tilting frame 120 with the stable driving force and precise angle control required for tilting, so as to ensure that the tilting frame 120 is in a horizontal or a certain tilt angle state.

[0047] In some embodiments of this utility model, a limiting rod 230 is provided between the two side plates 160. The limiting rod 230 is located on the side of the flipping frame 120 away from the rotating shaft 170 and is used to limit the position of the raw material package.

[0048] When the tilting frame 120 is in a horizontal receiving state, the limiting rod 230 can constrain the position of the raw material package on the roller 130, preventing it from shifting or slipping due to conveying inertia, thus ensuring the reliability of the roller 130 receiving the material.

[0049] In some embodiments of this utility model, reference is made to Figure 4 It also includes a support assembly, which includes a lifting block 210 and a second cylinder 220 that drives the lifting block 210 to rise and fall. The lifting block 210 is located away from the rotating shaft 170 and is used to abut against the bottom of the tilting frame 120.

[0050] When the tilting frame 120 is in a horizontal position, the second cylinder 220 drives the lifting block 210 to rise. The lifting block 210 abuts against the bottom of the tilting frame 120, forming an additional support point, which significantly reduces the load on the rotating shaft 170 and prevents the tilting frame 120 from tilting and thus failing to complete vacuum packaging.

[0051] In the description of this specification, references to terms such as "an embodiment," "some embodiments," "illustrative embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention.
