[0044] The detachable design increases the convenience of maintenance of the reel member 2. At the same time, when replacing the reel member 2, it can be directly replaced with a reel member 2 equipped with materials, thereby reducing the installation time of the reel member 2 and affecting the subsequent process flow.

[0045] For reference Figure 1 The present application includes a reel member 2 including a connecting plate 21, a fixing plate 22 and a round rod 23; the connecting plate 21 is adapted to the width of the support frame 1 and is installed on the support frame 1 by bolts, and two fixing plates 22 are provided, which are symmetrically fixedly connected to the surface of the connecting plate 21; a round rod 23 is provided in the middle of the two fixing plates 22, and both ends of the round rod 23 are connected to the fixing plate 22, and the connection method can be set to be connected through a rotating shaft;

[0046] In one embodiment, the reel 2 is arranged at the end of the material production line to directly receive the prepared material; thus, after the material is made into a roll, the reel 2 with the material can be directly mounted on the support frame 1 for use, which can increase the smoothness of the equipment in use;

[0047] It should be noted that the material is a rolled plastic product with patterns, and the patterns are set according to production requirements.

[0048] For reference Figure 1 The material on the reel 2 is fed into the working area 3 for working, thereby sealing the bag through cutting and hot pressing.

[0049] For reference Figure 1-4 The working area 3 includes a bearing member 31, a pushing member 32, a cutting member 33 and a hot pressing member 34; the pushing member 32 is fixedly connected to the support frame 1, and the pushing member 32 is arranged in the bearing member 31 for pushing the material penetrated therein to move outward; the cutting member 33 is arranged on the bearing member 31 and downwardly corresponds to the side of the pushing member 32 pushing the material to move outward; the hot pressing member 34 is fixedly connected to the bearing member 31 for packaging;

[0050] The carrier 31 includes an outer shell 311, a carrier plate 312 and a weight plate 313; the outer shell 311 is fixedly connected to the support frame 1 and corresponds to the front and rear of the round rod 23; the carrier plate 312 is fixedly connected to the side of the outer shell 311 away from the support frame 1; the weight plate 313 is located at the lower side of the carrier plate 312 and is fixedly connected to the surface of the outer shell 311; a lower recess 315 is provided on the weight plate 313, and an opening 314 connected to the lower recess 315 is provided on the outer shell 311; when the material is transported into the outer shell 311, the material is transported to the lower recess 315 through the opening 314, and the thickness of the material is carried by the height of the lower recess 315; when the front end of the packaged item is fed into the carrier plate 312 and the weight plate 313, the influence between the item to be packaged and the material is reduced, thereby reducing the deviation of the material and affecting the packaging effect.

[0051] For reference Figure 1 The pusher 32 includes a motor 321 and a booster rod 322; the motor 321 is arranged on the outer surface of the housing 311, which is convenient for subsequent maintenance work; the booster rod 322 is arranged inside the housing 311, so that the output end of the motor 321 is connected to one end of the booster rod 322, and the booster rod 322 is driven by the motor 321 to rotate; the booster rod 322 is arranged in the housing 311 in a horizontal manner, and the top surface of the booster rod 322 is highly connected to the bottom of the opening 314; and a part of the booster rod 322 is connected to the opening 314 ; Therefore, when the material enters the opening 314, the middle will contact the upper side of the booster rod 322; thereby, the material is driven forward during the rotation of the booster rod 322; in order to further increase the boosting effect of the booster rod 322, a plurality of anti-slip protrusions 323 are provided on the booster rod 322, so that the protective protrusions can contact the material through rotation, thereby accelerating the boosting effect; however, during the contact process, the material will be against the top of the opening 314, so that the friction between the material and the opening 314 can be reduced by polishing the top of the opening 314, thereby reducing the possibility of jamming.

[0052] For reference Figure 3-4 The cutting member 33 includes a first electric slide 331 and a cutting disc 332. The first electric slide 331 is disposed on the upper surface of the housing 311.

[0055] After being cut by the cutting piece 33, the material is located in the lower recess 315, and the heat sealer 342 is driven by the second electric slide 341 to move up and down, so that the bag-like items to be sealed are placed on the weight-bearing plate 313, and the heat sealer 342 moves downward and presses on the required sealing position to seal; in the process of pressing down, the material will also be affected by the heat pressure and bonded to the sealing position, thereby increasing the exquisiteness of the sealing position, thereby improving the external image of the product and increasing the desire to buy.

[0056] In the utility model, the working steps of the device are as follows:

[0057] 1. First, install the reel 2 with the material on the support frame 1, and insert the material on the reel 2 into the carrier 31;

[0058] 2. Secondly, the length of the material required for a single time is determined by setting the arc of a single rotation of the motor 321 in the pusher 32, and the material is pushed into the lower recess 315, and the motor 321 stops working;

[0059] 3. Then, the material is cut by the cutting member 33, and the bagged products to be packaged are placed in the middle of the connection between the carrying plate 312 and the load-bearing plate 313 during cutting;

[0060] 4. Finally, when the cutting is completed, the hot pressing member 34 moves downward to seal the opening of the bagged product through hot pressing, and presses the material on the sealing portion to form a complete bag sealing effect.
