[0022] 1. The utility model uses a handheld handle to pull one side of the PE protective film cylinder sleeved on the outer surface of the bracket rod backward along the bottom of the shell, and then covers the PE protective film body on one side of the required packaging carton. After covering, the staff holds the handle and pushes the shell vertically so that the two side edges of the shell are tightly attached to the covered PE protective film body. Then the staff turns on the external power supply of the motor and starts the motor. The output end of the motor starts to drive one of the rotating columns to rotate forward, and the positive rotation of the rotating column drives one of the gears to rotate. At this time, the chain located on the outer surface of one of the gears also rotates accordingly, and the force generated by the rotation of the chain drives the other gear to rotate forward. At this time, the cylinder on the surface of the chain also moves and pushes the slider to move. The fixed plate also moves horizontally due to the force generated by the push of the slider. At this time, the sliding plate embedded in the hollow partition also moves accordingly. When the two side edges of the bottom of the shell fit in place, the fixed plate moves horizontally. When the two sides of the PE protective film body are touched by the elastic force of multiple springs, the outer surfaces of multiple silicone scrapers under the flat plate begin to stick to the surface of the PE protective film body.

Previously, the two limit pins were pushed by the elastic force of spring three and were always embedded in the limit holes on both sides of the outer surface of the pop-up plate. After the limit pins are pulled out, the pop-up plate is quickly popped out by the elastic force of spring two. The telescopic column two limits the pop-up trajectory of spring two to prevent it from deviating. At this time, the PE protective film body between the pop-up plate and the blade is pressed onto the blade edge by the notch in the pop-up plate, thereby completing the cutting operation, thereby achieving a better cutting of the tail of the PE protective film body, and being able to neatly cut the tail of the PE protective film body, thereby improving the cutting effect of the tail of the PE protective film body and improving the cutting quality of the PE protective film body after packaging.

[0035] In this embodiment, by holding the handle 101, one side of the PE protective film tube 104 mounted on the outer surface of the bracket rod 103 is pulled back along the bottom of the shell 1, and then the PE protective film body is covered on one side of the desired packaging carton. After covering, the staff holds the handle 101 and pushes the shell 1 vertically so that the two side edges of the shell 1 are tightly attached to the PE protective film body after covering. Then the staff turns on the external power supply of the motor 105, starts the motor 105, and the output end of the motor 105 starts to drive one of the rotating columns 117 The positive rotation of the rotating column 117 drives one of the gears 113 to rotate. At this time, the chain 114 located on the outer surface of one of the gears 113 also rotates accordingly. The force generated by the rotation of the chain 114 drives the other gear 113 to rotate forward. At this time, the cylinder 116 on the surface of the chain 114 also moves and pushes the slider 115 to move. The fixed plate 112 is also pushed by the force generated by the slider 115 to move horizontally. At this time, the sliding plate 111 embedded in the hollow partition 110 is also As the movement proceeds, when the two side edges of the bottom of the shell 1 are attached to the two sides of the PE protective film body, the outer surfaces of the multiple silicone scrapers 107 below the flat plate 106 begin to adhere to the surface of the PE protective film body through the elastic force of multiple springs 109. Through the continuous movement of the sliding plate 111, the multiple silicone scrapers 107 begin to move horizontally on the surface of the PE protective film body, and the scraping force generated by the multiple silicone scrapers 107 is used to expel the air inside the PE protective film body. When the first exhaust is not complete, there will be some bubbles inside the PE protective film body. At this time, through the continuous rotation of the chain 114, the flat plate 106 as a whole can circulate back and forth on the surface of the PE protective film body, thereby repeatedly exhausting the air inside the PE protective film body, so that the PE protective film body is closely attached to the surface of the required packaging box, thereby facilitating better exhaust treatment of the PE protective film body during packaging, preventing some small bubbles from being incompletely exhausted due to one exhaust treatment, and repeatedly exhausting a certain area, thereby improving the exhaust efficiency of the PE protective film body during packaging.
[0036] Example 2, as Figure 1-7As shown, the bottom of the shell 1 is fixedly connected to the blade 2 near the edge, both sides of the outer surface of the shell 1 are fixedly connected with long plates 201, the inner sides of the outer surfaces of the two long plates 201 are fixedly connected with connecting plates 208, the top of the connecting plate 208 is fixedly connected to telescopic columns 203 on both sides near the edge, the top of the connecting plate 208 is fixedly connected to springs 202 on both sides near the edge, the tops of the two telescopic columns 203 are fixedly connected to pop-up plates 204, the bottom of the pop-up plate 204 is fixedly connected to one end of spring 202 on both sides near the edge, the top of the connecting plate 208 is fixedly connected to vertical plates 205 on both sides near the edge, and the two vertical plates 205 are movably embedded with limit pins 206, one side of the outer surface of the limit pin 206 is fixedly connected to spring three 207, and one end of the spring three 207 is fixedly connected to one side of the outer surface of one of the vertical plates 205.
[0037] In this embodiment, the two limit pins 206 are quickly pulled out. Previously, the two limit pins 206 were pushed by the elastic force of spring three 207 and were always embedded in the limit holes on both sides of the outer surface of the pop-up plate 204. After the limit pins 206 are pulled out, the pop-up plate 204 is quickly popped out by the elastic force of spring two 202. The telescopic column two 203 limits the pop-up trajectory of spring two 202 to prevent it from deviating. At this time, the PE protective film body between the pop-up plate 204 and the blade 2 is pressed to the blade 2 by the notch in the pop-up plate 204, thereby completing the cutting operation, thereby achieving better cutting of the tail of the PE protective film body, and being able to neatly cut the tail of the PE protective film body, thereby improving the cutting effect of the tail of the PE protective film body and improving the cutting quality of the PE protective film body after packaging.
[0038] Working principle: When packaging, the staff first holds the handle 101 and pulls one side of the PE protective film tube 104 mounted on the outer surface of the bracket rod 103 backward along the bottom of the shell 1, and then covers the PE protective film body on one side of the required packaging carton. After covering, the staff holds the handle 101 and pushes the shell 1 vertically so that the two side edges of the shell 1 are close to the PE protective film body after covering. Then the staff turns on the external power supply of the motor 105 and starts the motor 105. The output end of the motor 105 starts to drive one of the rotating columns 117 to rotate forward, and the forward rotation of the rotating column 117 drives one of the gears 113 to rotate as well. At this time, the chain 114 located on the outer surface of one of the gears 113 also rotates. The force generated by the rotation of the chain 114 drives another gear 113 to rotate forward. At this time, the cylinder 116 on the surface of the chain 114 also moves and pushes the slider 115 to move. The fixed plate 112 is also moved horizontally by the force generated by the slider 115. At this time, the sliding plate 111 embedded in the hollow partition 110 also moves accordingly. When the two side edges of the bottom of the shell 1 are attached to the two sides of the PE protective film body, the outer surfaces of the multiple silicone scrapers 107 under the flat plate 106 begin to cling to the surface of the PE protective film body through the elastic force of multiple springs 109. Through the continuous movement of the sliding plate 111, the multiple silicone scrapers 107 begin to move horizontally on the surface of the PE protective film body. The flat plate 106 moves and utilizes the scraping force generated by multiple silicone scrapers 107 to discharge the air inside the PE protective film body. When the first discharge is not complete, there will be some bubbles inside the PE protective film body. At this time, through the continuous rotation of the chain 114, the flat plate 106 can perform a circular reciprocating motion on the surface of the PE protective film body to repeatedly discharge the air inside the PE protective film body, so that the PE protective film body is tightly attached to the surface of the required packaging box, thereby achieving better exhaust treatment of the PE protective film body during packaging, preventing some small bubbles from being exhausted completely due to one exhaust treatment, and repeatedly exhausting a certain area, thereby improving the exhaust efficiency of the PE protective film body during packaging, and when the exhaust is completed, the PE protective film body needs to be cleaned. The body is cut, and the staff quickly pulls out the two limit pins 206. Previously, the two limit pins 206 were pushed by the elastic force of the spring three 207 and were always embedded in the limit holes on both sides of the outer surface of the pop-up plate 204. After the limit pins 206 are pulled out, the pop-up plate 204 is quickly popped out by the elastic force of the spring two 202, and the telescopic column two 203 limits the pop-up trajectory of the spring two 202 to prevent it from deviating. At this time, the PE protective film body between the pop-up plate 204 and the blade 2 is pressed onto the blade 2 by the notch in the pop-up plate 204, thereby completing the cutting operation, thereby achieving a better cutting of the tail of the PE protective film body, and being able to neatly cut the tail of the PE protective film body, thereby improving the cutting effect of the tail of the PE protective film body.Improved the cutting quality of PE protective film after packaging.
