If the signal continues after the bundle is wrapped, the PLC determines that the bundle is valid and allows the goods to enter the downstream process; if the signal is interrupted, it is considered a failure. The entire detection device is a small module. If the threaded hole positioning is misaligned when it is fixed with bolts, it will cause damage to the entire device, requiring the entire device to be reconfigured. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tape-packing detection device for a PP tape packing machine, comprising a mounting plate, a mounting component, and a limiting block: the bottom of the mounting plate is connected to the PP tape packing machine; the mounting component is connected to the bottom of the mounting plate, and two mounting components are provided; the limiting block is located on one side of the mounting component, and two limiting blocks are provided on the bottom of the mounting plate, with the two limiting blocks located on different sides of the two mounting components respectively.

[0020] 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.
[0021] Example 1
[0022] like Figure 1-5As shown, a strapping detection device for a PP strapping machine includes a mounting plate 1, mounting parts 2, and limiting blocks 3. The bottom of the mounting plate 1 is connected to the PP strapping machine. The mounting plate 1 serves as the mounting base and should be made of a corrosion-resistant and moisture-proof material. The PP strapping machine has slots facing opposite directions for the mounting parts 2 to be inserted into. To secure the mounting plate 1 and the PP strapping machine without bolts, mounting parts 2 are provided on the mounting plate 1 for fixing the mounting plate 1 and the PP strapping machine. Two mounting parts 2 are provided, such as... Figure 2 and Figure 3 As shown, the two mounting components 2 are symmetrically distributed on the center line at the bottom of the mounting plate 1.
[0023] To prevent over-reset of mounting component 2 during reset, the limiting block 3 is positioned on one side of mounting component 2, such as... Figure 2 and Figure 3 As shown, two limiting blocks 3 are provided at the bottom of the mounting plate 1, and the two limiting blocks 3 are located on different sides of the two mounting parts 2. On the one hand, the limiting blocks 3 will prevent the mounting parts 2 from over-resetting during reset. On the other hand, the limiting blocks 3 are located on different sides of the two mounting parts 2, so that the rotation directions of the two mounting parts 2 are different, preventing the mounting plate 1 from deflecting during use, which would cause the entire mounting plate 1 to separate from the PP strapping machine.
[0024] Specifically, when using it, first rotate the mounting part 2 to... Figure 3 At the designated location, the mounting plate 1 is connected to the PP strapping machine. At this time, the PP strapping machine has a slot for the mounting part 2 to be inserted. After the mounting part 2 is connected to the slot, the mounting part 2 is released and will reset. To avoid the mounting part 2 from over-resetting during reset, the limiting block 3 is placed on one side of the mounting part 2.
[0025] The mounting plate 1 is internally connected to two bearings 11, each bearing having rolling steel balls / rollers that allow the rolling elements to roll between the raceways of the inner and outer rings, restricting rotational motion to the inner ring while keeping the outer ring stationary. This is publicly available technology and will not be described in detail below. The bearing 11 is internally connected to a rotating knob 12, the top and bottom of which extend outside the bearing 11. The rotating knob 12 is fixed inside the bearing 11. During use, the design of the bearing 11 allows the rotating knob 12 to be fixed to the mounting plate 1 while still being able to rotate.
[0026] Mounting component 2 includes a snap-fit plate 21 disposed at the bottom of mounting plate 1, wherein snap-fit plate 21 is as follows: Figure 2 and Figure 3As shown, it has a rectangular design and is used to connect with the slot of the PP strapping machine. It defines the mounting plate 1 and the top of the snap-fit plate 21 is connected to the rotating plate 22. It should be noted that the bottom of the rotating plate 22 is connected to the bottom of the rotating knob 12. Specifically, when the rotating knob 12 rotates, it will drive the rotating plate 22 and the snap-fit plate 21 to rotate synchronously.
[0027] A return spring 23 is connected to the top of the rotating plate 22. The return spring 23 is a torsion spring. The type of return spring 23 should be selected to match the equipment. When there is no external force, the return spring 23 will limit the locking plate 21 to [position missing]. Figure 2 At the indicated position, after being subjected to force, the snap-fit plate 21 is rotated to... Figure 3 Upon release, the snap-fit plate 21 will be reset to its original position under the torque of the return spring 23. Figure 2 It should be noted that the top of the return spring 23 is connected to the bottom of the mounting plate 1, and the return spring 23 is wrapped around the knob 12 below the mounting plate 1.
[0028] The effect achieved by the entire first embodiment is that, firstly, the mounting part 2 is rotated to... Figure 3 At the designated location, when connecting the mounting plate 1 to the PP strapping machine, the PP strapping machine has slots for the mounting component 2 to insert into. After the mounting component 2 aligns with the slot, releasing the mounting component 2 will cause it to reset. To prevent over-reset during reset, a limiting block 3 is positioned on one side of the mounting component 2. The limiting block 3 prevents over-reset during reset and, by being located on different sides of the two mounting components 2, ensures that the two components rotate in different directions, preventing the mounting plate 1 from deflecting during use and causing separation between the mounting plate 1 and the PP strapping machine. The return spring 23, during use, will limit the locking plate 21 to... Figure 2 At the indicated position, after being subjected to force, the snap-fit plate 21 is rotated to... Figure 3 Upon release, the snap-fit plate 21 will be reset to its original position under the torque of the return spring 23. Figure 2 Location.
[0029] Example 2
[0030] like Figure 1-5 As shown, a tape-making detection device for a PP tape packaging machine has an adsorption block 14 connected to the center of the bottom of the mounting plate 1. The adsorption block 14 is a magnet. Specifically, the part connecting the PP tape packaging machine and the adsorption block 14 should be made of iron, and the plane where the lowest point of the adsorption block 14 is located is coplanar with the plane where the lowest point of the snap-fit plate 21 and the limiting block 3 are located.
[0031] The top of the mounting plate 1 is connected to an infrared detection head 13, which is divided into signal transmitter and receiver. In actual use, two are usually installed, one for signal transmitter and one for signal receiver. The infrared transmitter actively emits an infrared beam of a specific wavelength; while the receiver captures the infrared signal reflected by the target object and converts it into a current or voltage signal. The infrared detection head 13 is located at the center of the bottom of the mounting plate 1 and is used in conjunction with a PP strapping machine.
[0032] The effect achieved by the entire second embodiment is that the part connecting the PP strapping machine and the adsorption block 14 should be made of iron material, and the plane where the lowest point of the adsorption block 14 is located is coplanar with the plane where the lowest point of the snap-fit plate 21 and the limiting block 3 are located, so as to facilitate the adsorption of the adsorption block 14 and initially position the mounting plate 1.
[0033] Working principle: When using the strapping detection device of this PP strapping machine, an external power supply is required. First, rotate the mounting part 2 to... Figure 3 At the designated location, the mounting plate 1 is connected to the PP strapping machine. At this time, the PP strapping machine has a slot for the mounting part 2 to be inserted. After the mounting part 2 is connected to the slot, the mounting part 2 is released and will reset. To prevent the mounting part 2 from over-resetting during reset, the limiting block 3 is placed on one side of the mounting part 2. The limiting block 3 prevents the mounting part 2 from over-resetting during reset. On the other hand, the limiting block 3 is located on different sides of the two mounting parts 2, so that the rotation directions of the two mounting parts 2 are different, preventing the mounting plate 1 from deflecting during use and causing the entire mounting plate 1 to separate from the PP strapping machine.
[0034] Secondly, the part connecting the PP strapping machine and the adsorption block 14 should be made of iron, and the plane where the lowest point of the adsorption block 14 is located should be coplanar with the plane where the lowest point of the snap-fit plate 21 and the limit block 3 are located, so as to facilitate the adsorption of the adsorption block 14. The mounting plate 1 is initially positioned, and finally the work of the strapping detection device of the PP strapping machine is completed.
