Description

Technical Field

[0001] The utility model relates to the technical field of vacuum negative pressure bagging, and in particular to a zinc oxide vacuum negative pressure bagging device. Background Art

[0002] Zinc oxide vacuum negative pressure bagging equipment is an automated equipment specially used for packaging zinc oxide powder or other similar materials. This equipment usually integrates vacuum packaging technology, which can extract the air in the bag during the packaging process, thereby effectively preventing the oxidation and moisture absorption of the zinc oxide powder and maintaining the quality of the product.

[0003] When the zinc oxide vacuum negative pressure bagging equipment is drawing a vacuum, the bag filled with zinc oxide material must first be placed under the vacuum drawing machine, and the vacuum straw must be inserted into the middle of the bag. However, the vacuum drawing machines on the market generally place the bags upright, causing all the materials to accumulate in one place. There is no material at the connection between the material bag and the vacuum straw. When the vacuum is drawn, the bags are all stuck together, resulting in the gas below not being drawn up. The residual gas will reduce the quality of the zinc oxide material. Since the vacuum is not fully drawn, the packaging bag is more likely to break and be damaged. Utility Model Content

[0004] The utility model provides a zinc oxide vacuum negative pressure bagging device, which solves the problem in the prior art that material accumulation causes dead corners inside the packaging bag and makes it difficult to completely extract the gas.

[0005] The technical solution of the utility model is as follows:

[0006] A zinc oxide vacuum negative pressure bagging device, comprising a base and a vacuum pump, wherein one side of the base is fixedly connected to a support plate, and the vacuum pump is fixedly mounted on an outer side wall of the base facing the support plate, and further comprising:

[0007] A mounting plate, the mounting plate being fixedly arranged above the support plate;

[0018] A first clamping plate, the first clamping plate being fixedly connected to the highest point of the fixing opening;

[0019] A second clamping plate is fixedly connected to the lowest point of the fixing opening.

[0020] Preferably, the suction mechanism comprises:

[0021] A suction port, the suction port being provided on the support plate;

[0022] Suction pipes, two of which are fixedly connected between the first and second clamping plates, and each of which passes through the suction port and extends toward one end of the base;

[0023] A connecting pipe is connected to each of the suction pipes, and the other end of the connecting pipe is connected to the output end of the vacuum pump.

[0031] The working principle and beneficial effects of the utility model are as follows:

[0032] In the utility model, when the bagged zinc oxide material is vacuumed, the electric cylinder is first started. When the packaging bag is placed under the electric cylinder, the push rack is pushed out to make the push plate hammer the packaging bag to make the zinc oxide material inside the packaging bag flat. The packaging bag is fixed using the first and second splints, and the suction tube is placed inside the packaging bag.

DETAILED DESCRIPTION

[0040] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] like Figures 1 to 5 As shown, this embodiment proposes a zinc oxide vacuum negative pressure bagging equipment, including a base 1 and a vacuum pump 2. A support plate 3 is fixedly connected to one side of the base 1. The vacuum pump 2 is fixedly installed on the outer wall of the base 1 facing the support plate 3. It also includes a mounting plate 4, a hammering mechanism, a fixing mechanism, a suction mechanism and a conveying mechanism. The mounting plate 4 is fixedly arranged above the support plate 3. The hammering mechanism is arranged on the top of the mounting plate 4 for hammering the packaging bag flat. The fixing mechanism is arranged in the middle position of the support plate 3 facing the base 1 for fixing the packaging bag. The suction mechanism is arranged on the fixing mechanism for extracting the gas inside the packaging bag. The conveying mechanism is arranged on one side of the base 1 for conveying the processed packaging bag.

[0042] In this embodiment, the hammering mechanism includes an electric cylinder 101, a push rack 102 and a push plate 103. The electric cylinder 101 is mounted on the mounting plate 4. The output end of the electric cylinder 101 is fixedly connected to the push rack 102, and the push plate 103 is fixedly connected to the other end of the push rack 102. The push plate 103 is surrounded by an arc surface 5, mainly to prevent the push plate 103 from breaking the packaging bag. The arc surface 5 makes the force distribution more uniform during hammering. It should be added that the zinc oxide material in the packaging bag does not completely fill the entire bag. One-third of the bag needs to be left when the vacuum is extracted. There are gaps to prevent the zinc oxide material from overflowing after vacuuming, and since the packaging bags filled with zinc oxide material are all gathered at the bottom of the bags, gaps will appear at the openings of the packaging bags. When the gaps are completely extracted by vacuuming, the packaging bags will stick together tightly, making it difficult to vacuum the area with zinc oxide material at the bottom. Therefore, it is necessary to use the push plate 103 to hammer the packaging bags flat and evenly distribute them in the packaging bags before vacuuming. Moreover, when the electric cylinder 101 pushes out the push plate 103, the speed can be set to a slow state so that the zinc oxide material in the packaging bags will not be hammered out.

[0043] In this embodiment, the fixing mechanism includes a fixing port 201, a splint 1 202 and a splint 203. A fixing port 201 is opened on the top of the support plate 3. The splint 1 202 is fixedly connected to the highest point of the fixing port 201, and the splint 203 is fixedly connected to the lowest point of the fixing port 201. The splint 1 202 and the splint 2 203 are set to be immovable and are made of silicone material. This is mainly to expand and fix the packaging bag on the fixing clamp, so that the packaging bag reduces movement during vacuuming to avoid affecting the vacuuming work. At the same time, the splint 1 202 and the splint 2 203 made of silicone material will not easily break the packaging bag.

[0044] In this embodiment, the suction mechanism includes a suction port 301, a suction tube 302 and a connecting tube 303. The suction port 301 is opened on the support plate 3. Two suction tubes 302 are fixedly connected between the splint 1 202 and the splint 2 203, and each suction tube 302 extends through the suction port 301 toward one end of the base 1. Each suction tube 302 is connected to a connecting tube 303, and the other end of the connecting tube 303 is connected to the output end of the vacuum pump 2.

[0045] In this embodiment, the conveying mechanism includes a support 401, a motor 402, a fixed shaft 403, a transmission wheel 404 and a conveyor belt 405. The support 401 is fixedly connected to one side of the base 1, and a turning port is provided on the support 401 away from the base 1. The motor 402 is installed on one of the supports 401 close to the base 1. A fixed shaft 403 is fixedly connected to the output end of the motor 402, and the other fixed shaft 403 is rotatably connected to the turning port. The two fixed shafts 403 are fixedly connected to the transmission wheels 404, and the conveyor belt 405 is tensioned on the two transmission wheels 404.

[0046] In summary, the working principle of the zinc oxide vacuum negative pressure bagging equipment is as follows: when the packaging bag filled with zinc oxide material is vacuumed and stored, the electric cylinder 101 is first started. When the packaging bag is placed under the electric cylinder 101, the push rack 102 is pushed out to make the push plate 103 beat the packaging bag to make the packaging bag flat. After the packaging bag is opened manually, it is respectively put on the top of the splint 1 202 and the bottom of the splint 203 to open the packaging bag. The purpose is to enable the suction pipe 302 between the splint 1 202 and the splint 203 to be inserted into the packaging bag to normally draw vacuum. The vacuum pump 2 is started, and the vacuum pump 2 is connected through the connecting pipe 303 and the suction pipe 302. The tube 302 extracts the gas inside the flattened packaging bag after beating. After the vacuuming is completed, the packaging bag is removed from the plywood 1 202 and the plywood 2 203, and the motor 402 is started. The packaging bag is transmitted by the conveyor belt 405, and the conveyor belt 405 has a sloped surface to avoid falling during the transmission process. The packaging bag is transported to a designated location for storage, and then the push plate 103 is used to beat the next zinc oxide material packaging bag that needs to be vacuumed, and then the plywood 1 202 and the plywood 2 203 are used to fix and start the vacuum pump 2 to vacuumize. After the end, it is still transported to the designated location through the conveyor belt 405, thereby circulating the vacuum production line.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
