[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] like Figure 1-4As shown, a semi-automatic PP strapping machine includes a device body 1, a strapping conveyor structure 11, a displacement groove 3, a moving structure 2, a sliding block 22, a fixed base 24, and a limiting connecting plate 21. The device body 1 has a displacement groove 3, which is integrally molded with the device body 1 and is used to allow the moving structure 2 to slide, providing a limited sliding distance for the moving structure 2. Part of the moving structure 2 is slidably connected within the displacement groove 3. It should be noted that during use, the moving structure 2 will separate the food material to be packaged from the top of the device body 1, reducing the probability of friction between the food material to be packaged and the top of the device body 1, thus preventing wear on the food material during use and causing ineffective packaging of the entire machine.

[0024] The movable structure 2 includes a sliding block 22, a fixed base 24, and a limiting connecting plate 21. Specifically, the sliding block 22 is horizontally slidably connected within the displacement groove 3. The displacement groove 3 has a concave design, while the bottom of the sliding block 22 has a convex design, allowing the sliding block 22 to slide within the displacement groove 3 without slipping. The length of the displacement groove 3 is the sliding length of the sliding block 22, and the top of the sliding block 22 extends beyond the displacement groove 3. It should be noted that the length of the fixed base 24 is greater than the depth of the displacement groove 3. To facilitate the movement of the fixed base 24 and further reduce the probability of contact between the food material and the top of the device body 1, the top of the sliding block 22 is connected to the fixed base 24. There is a certain gap between the fixed base 24 and the device body 1. The fixed base 24 supports the food material and moves it, ensuring that the food material remains stationary relative to the fixed base 24 during movement, reducing wear and tear. A limiting connecting plate 21 is connected to one side of the fixed base 24. The limiting connecting plate 21... Figure 1 The limit connecting plate 21 and the fixed base 24 are located on one side of the cable tie conveyor structure 11 and are used to limit the movement of food materials to reduce the probability of food materials falling. The limit connecting plate 21 and the fixed base 24 are designed in an "L" shape to limit the position of food materials when they move.

[0025] The top of the fixed base 24 is connected to a corrugated surface 23, which is made of rubber. The corrugated surface 23 is used to increase the friction between the food material and the fixed base 24, thereby further reducing the probability of the food material falling off the fixed base 24.

[0026] Two sets of displacement grooves 3 are provided on the device body 1. The two sets of displacement grooves 3 are symmetrically distributed on the transverse central axis of the device body 1. The design of the two sets, and the fact that the adjacent moving structures 2 are not connected, reduces the probability of the PP belt getting tangled in the moving structures 2 during packaging. At the same time, they are located on both sides of the central line of the device body 1, which increases the stability of the moving structures 2 when they move.

[0027] The overall effect of this embodiment is that the moving structure 2 separates the food material to be packaged from the top of the device body 1 during use, reducing the probability of friction between the food material and the top of the device body 1, thus preventing wear on the food material and avoiding ineffective packaging. Furthermore, there is a certain gap between the fixed base 24 and the device body 1. The fixed base 24 supports the food material and moves it, keeping it stationary relative to the fixed base 24 during movement, further reducing wear. A limiting connecting plate 21 is connected to one side of the fixed base 24. The limiting connecting plate 21... Figure 1 The limit connecting plate 21 and the fixed base 24 are located on one side of the cable tie conveyor structure 11 and are used to limit the movement of food materials to reduce the probability of food materials falling. The limit connecting plate 21 and the fixed base 24 are designed in an "L" shape to limit the position of food materials when they move.

[0028] Example 2

[0029] like Figure 1-4 As shown, a semi-automatic PP strapping machine has a strapping outlet 12 on its body 1. The strapping outlet 12 is located on the transverse central axis at the bottom of the body 1. The strapping outlet 12 separates the displacement groove 3 and the moving structure 2, and the displacement groove 3 and the moving structure 2 are symmetrically distributed along the strapping outlet 12, reducing the phenomenon of food materials falling off during movement. Simultaneously, as... Figure 1 The movable structures 2 shown are not connected to each other, which reduces the probability of the PP belt getting tangled with the movable structures 2 during packaging.

[0030] A cable tie conveyor structure 11 is connected to one side of the device body 1. The surface of the cable tie conveyor structure 11 is provided with a groove for winding PP straps for packaging. When in use, the PP strap extends into the device body 1 and is connected to the cable tie outlet 12.

[0031] The device body 1 has a belt end pressing and fastening, strapping tightening, heat fusion bonding and cutting, and reset standby structure. Specifically, when the belt end pressing and fastening is used, the right top body rises to press the front end of the upper belt to prevent springback; then the left top body rises to press the overlapping part of the lower belt to fix the area to be welded.

[0032] The strapping tightening mechanism uses a drive mechanism (motor and reducer) to power the tightening wheel, forcefully shrinking the strapping to the preset tension to ensure a secure tie. Some models employ a dual-motor design to enhance tightening efficiency.

[0033] In use, the hot melt bonding and cutting process involves inserting a heating plate at approximately 200°C between two layers of tape to melt the surface of the polypropylene. Then, the top knife moves to simultaneously cut off the excess tape. Finally, pressure curing is performed, using a pressing mechanism to maintain pressure and cool and bond the molten tape to form a seamless joint.

[0034] Finally, after the bonding is completed through the reset standby, the top body and heating plate of each component will automatically reset. If there is no operation within 60 seconds, it will enter the standby state for energy saving. The above is the conventional publicly disclosed technology of this PP tape semi-automatic packaging machine, which will not be repeated below.

[0035] The overall effect of this second embodiment is that the cable tie outlet 12 separates the displacement groove 3 and the moving structure 2, and the displacement groove 3 and the moving structure 2 are symmetrically distributed along the cable tie outlet 12, reducing the phenomenon of food materials falling off during movement. Figure 1 The movable structures 2 shown are not connected to each other, which reduces the probability of the PP belt getting tangled with the movable structures 2 during packaging.

[0036] Working Principle: When using this PP belt semi-automatic packaging machine with an external power supply, the moving structure 2 first separates the food material to be packaged from the top of the device body 1, reducing the probability of friction between the food material and the top of the device body 1. This prevents wear on the food material during use, which could lead to ineffective packaging. Furthermore, there is a certain gap between the fixed base 24 and the device body 1. The fixed base 24 supports the food material and moves it, keeping it stationary relative to the fixed base 24 during movement, further reducing wear. A limiting connecting plate 21 is connected to one side of the fixed base 24. The limiting connecting plate 21... Figure 1 The limit connecting plate 21 and the fixed base 24 are located on one side of the cable tie conveyor structure 11 and are used to limit the food material when it is displaced, so as to reduce the probability of the food material falling. The limit connecting plate 21 and the fixed base 24 are designed in an "L" shape to limit the position of the food material when it moves, and finally complete the work of the PP strap semi-automatic packaging machine.
