Description

Technical Field

[0001] The utility model relates to an anti-adsorption mechanism, in particular to an anti-waste adsorption mechanism. Background Art

[0002] A bag making machine is a machine used to make various plastic packaging bags or other material packaging bags. During the bag making process, it is necessary to separate the excess material from the finished bags to prevent the waste from being adsorbed on the finished bags and affecting the subsequent processing and use. Therefore, a waste adsorption mechanism is required.

[0003] For example, a bag-making machine with a waste recycling function disclosed in a Chinese patent with the publication number CN216683543U belongs to the field of plastic packaging technology, and includes a base, a workbench is arranged on the upper surface of the base, a support frame is arranged on the upper surface of the inner wall of the workbench, an electric hydraulic rod and a first piston cylinder are arranged on the upper surface of the inner wall of the support frame, a lifting plate is fixedly connected to the bottom end of the electric hydraulic rod, and a first moving rod is fixedly connected to the upper surface of the lifting plate. The bag-making machine with a waste recycling function is provided with a fan, a connecting pipe, a blow pipe, a collection box, a lifting plate and a punching head. When the lifting plate drives the punching head to move downward to punch the original piece, the fan is started, and the fan rotates to suck the debris generated by the punching into the groove, and then the debris is blown into the collection box through the connecting pipe and the blow pipe for collection. The device can quickly collect the debris through the fan, avoid the difficulty of cleaning caused by the diffusion of the debris, and thus reduce labor consumption.

[0004] The above-mentioned existing anti-adsorption structure of the bag-making machine with waste recycling function has some problems when used. The waste in the groove is sucked into the inside of the connecting pipe by the fan, and then blown into the inside of the collection box by the fan. There are two problems:

[0005] First, most fans on the market use blades to drive air circulation. When waste passes through the fan, it is very easy to entangle on the blades, causing the blades to get stuck.

[0006] Second, the outside air is constantly blowing into the collection box, and the collection box is not equipped with exhaust holes and other mechanisms, which will cause the air pressure inside the collection box to become higher and higher until the air can no longer be drawn into the collection box and the air duct cannot be effectively formed, so that the air cannot effectively carry the waste into the collection box, or the collection box is not completely sealed, and the discharge of air will cause the waste to block the exhaust holes, which also fails to effectively form the air duct. Utility Model Content

[0007] The purpose of the utility model is to provide a waste adsorption prevention mechanism to solve the existing problems raised in the above background technology.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a waste adsorption prevention mechanism, comprising a workbench, a Venturi tube is fixedly installed under the workbench, a fan is fixedly installed under the workbench and at one end of the Venturi tube, the output end of the fan is fixedly connected to the Venturi tube, a connecting hose is fixedly connected to the other end of the Venturi tube, an upper cover is provided under the workbench and at the other end of the Venturi tube, a collecting tank is provided under the upper cover, a discharge pipe is fixedly installed in the upper cover, the discharge pipe is fixedly connected to the other end of the connecting hose, and an exhaust hole is provided in the upper cover.

[0009] Preferably, a groove is provided on the workbench, and the lower end of the groove is fixedly connected to the suction end of the venturi tube through a pipeline.

[0010] Preferably, a threaded connection edge is fixedly installed on the lower side of the upper cover, a threaded groove is provided on the inner edge of the collection tank, and the threaded connection edge and the threaded groove cooperate with each other.

[0011] Preferably, a suspension rod is fixedly mounted on the upper cover, and the other end of the suspension rod is fixedly connected to the bottom of the workbench.

[0012] Preferably, a filter is fixedly installed in the exhaust hole.

[0013] Preferably, handles are fixedly mounted on both sides of the collection tank, and a transparent observation window is embedded in the front of the collection tank.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. By starting the fan, air can be blown into the Venturi tube. Air is blown into the input end of the Venturi tube. According to the Venturi effect, a certain negative pressure will be formed in the inner cavity, thereby sucking the outside air and waste into the Venturi tube, and then transporting it to the discharge pipe through the connecting hose. Compared with the existing device, it can effectively avoid the problem of waste entanglement in the fan.

[0016] 2. By adding a certain amount of clean water into the collection tank, the lower end of the discharge pipe sinks into the clean water, so that the air will directly form bubbles and float up and be discharged through the exhaust hole. The waste enters the clean water and the surface will be wetted, making it difficult to be carried by the air, thus preventing the waste from continuing to be carried by the air and effectively preventing the waste from clogging the exhaust hole.

[0023] In this embodiment, air can be blown into the venturi tube 2 by starting the fan 201. Air is blown into the input end of the venturi tube 2, and a certain negative pressure is formed in the inner cavity according to the venturi effect, so that the outside air and the waste are sucked into the venturi tube 2 together. The venturi tube 2 is connected to the discharge pipe 301 through the connecting hose 202, so that the waste will enter the discharge pipe 301 together with the air. A mechanical structure is arranged inside the entire conveying mechanism, so as to effectively avoid the entanglement of the waste. A certain amount of clean water is added to the collection tank 4, and the lower end of the discharge pipe 301 sinks into the clean water, so that the air will directly form bubbles and float up, and be discharged through the exhaust hole 302. When the waste enters the clean water, the surface will be wetted, making it difficult to be carried by the air, so as to avoid the waste from being continued to be driven by the air, separate the waste from the air, and effectively avoid the waste from clogging the exhaust hole 302.

[0024] Among them, in order to achieve the purpose of fixing the collection tank 4, the present device is implemented by adopting the following technical scheme: a groove 101 is opened on the workbench 1, and the lower end of the groove 101 is fixedly connected to the suction end of the venturi tube 2 through a pipe, a threaded connection edge 304 is fixedly installed under the upper cover 3, and a threaded groove is opened on the inner edge of the collection tank 4, and the threaded connection edge 304 cooperates with the threaded groove, a suspension rod 305 is fixedly installed on the upper cover 3, and the other end of the suspension rod 305 is fixedly connected to the bottom of the workbench 1, and a filter screen 303 is fixedly installed in the exhaust hole 302.

[0025] The waste material separated after punching is collected by the groove 101, and the groove 101 is connected to the suction end of the venturi tube 2 through a pipe, so that the air will carry the waste material into the interior of the venturi tube 2, and the threaded connection edge 304 cooperates with the threaded groove to fix the collection tank 4 under the upper cover 3, and the upper cover 3 is fixed under the workbench 1 by the suspension rod 305, and the filter screen 303 prevents a small amount of escaping waste material from being discharged to the outside.

[0026] In order to facilitate observation of the collection situation inside the collection tank 4 , the device is implemented by the following technical solution: handles 402 are fixedly installed on both sides of the collection tank 4 , and a transparent observation window 401 is embedded in the front of the collection tank 4 .

[0027] The handle 402 is used to facilitate the removal of the collection tank 4 to pour out the collected waste, and the transparent observation window 401 is used to observe the collection situation inside the collection tank 4.

[0028] The working principle and use process of the utility model: when using, the device needs to be placed in a suitable position. First, a certain amount of clean water needs to be added to the inside of the collection tank 4 to ensure that the lower end of the discharge pipe 301 is submerged. Then, the fan 201 can be started to blow air into the venturi tube 2. Air is blown into the input end of the venturi tube 2. According to the venturi effect, a certain negative pressure will be formed in the inner cavity, so that the air and the waste in the groove 101 will be sucked into the venturi tube 2, and then transported to the inside of the discharge pipe 301 through the connecting hose 202. The lower end of the discharge pipe 301 sinks into the clean water, so that the air will directly form bubbles and float up, and be discharged through the exhaust hole 302. The waste enters the clean water, and the surface will be wetted, making it difficult to be carried by the air, so that it will be retained and stored in the collection tank 4, effectively sucking the waste and preventing the waste from being adsorbed on the packaging bag.
