In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0042] like Figure 1-Figure 2As shown, this embodiment provides a particle collecting device, which includes a powder collecting box 1, a fixed clamping mechanism 2, a screwing mechanism 3, a collecting mechanism 4 and a frame, wherein the powder collecting box 1, the fixed clamping mechanism 2, the screwing mechanism 3 and the collecting mechanism 4 are all arranged on the frame, and the frame plays a role of overall support. Specifically, a feed port 11 is provided on the powder collecting box 1, and the PP adhesive tape can enter the powder collecting box 1 through the feed port 11. The fixed clamping mechanism 2 is located on one side of the powder collecting box 1, and can clamp one end of the PP adhesive tape in the powder collecting box 1. The screwing mechanism 3 is located on the other side of the powder collecting box 1. The screwing mechanism 3 includes a movable clamping jaw 31 and a first linear driving member 34. The first linear driving member 34 is used to drive the movable clamping jaw 31 to move toward or away from the fixed clamping mechanism 2. The movable clamping jaw 31 can open and close on both sides of the other end of the PP adhesive tape to vibrate the PP adhesive tape to make the PP particles on the PP adhesive tape fall off. The collecting mechanism 4 is located below the powder collecting box 1, and the collecting mechanism 4 can collect the PP particles that fall from the PP adhesive tape. The first linear driving member 34 is specifically a first cylinder.

[0043] The particle collection device proposed in this embodiment, when in use, the operator puts the PP adhesive tape into the powder collection box 1 from the feed port 11 of the powder collection box 1, the fixed clamping mechanism 2 clamps one end of the PP adhesive tape, the movable clamping claw 31 clamps the other end of the PP adhesive tape, and continuously opens and closes on both sides of the PP adhesive tape to imitate the rubbing action of human hands, so that PP particles fall from the PP adhesive tape, and the first linear drive member 34 can drive the movable clamping claw 31 to move in the direction of approaching or away from the fixed clamping mechanism 2, so that the PP particles on the entire surface of the PP adhesive tape can fall, and the PP particles fall to the bottom of the powder collection box 1, which is convenient for the collection mechanism 4 to collect the PP particles in a centralized manner. The particle collection device provided in this embodiment, by setting the powder collection box 1, the powder collection box 1 provides a closed space for the collection of PP particles, prevents the waste of PP particles, and reduces environmental pollution; by setting the screwing mechanism 3, the screwing mechanism 3 is used to imitate the rubbing action of human hands, reduces the workload of the operator, improves the collection efficiency, and has a high degree of automation.

[0044] Furthermore, if Figure 2 As shown, the screwing mechanism 3 also includes a linear moving plate 33 and a screwing rotary driving member 32. The linear moving plate 33 is connected to the output end of the first linear driving member 34. The screwing rotary driving member 32 is arranged on the linear moving plate 33. The output end of the screwing rotary driving member 32 is connected to the movable clamping claw 31. The screwing rotary driving member 32 is specifically a first motor. When the movable clamping claw 31 is opened and closed on both sides of the PP adhesive tape, the screwing rotary driving member 32 drives the movable clamping claw 31 to rotate at a small angle, further improving the kneading effect of the movable clamping claw 31 on the PP adhesive tape, so that the PP particles are more likely to fall off the PP adhesive tape.

[0045] Furthermore, the screwing mechanism 3 further includes a screwing mounting frame 35 disposed on the frame, a guide rail 351 is disposed on the screwing mounting frame 35, a guide slider 331 is disposed on the linear moving plate 33, and the guide slider 331 is slidably matched with the guide rail 351. By providing the mutually matched guide slider 331 and the guide rail 351, a guide is provided for the linear moving plate 33 to slide along the screwing mounting frame 35, and the stability of the sliding process is ensured.

[0046] Furthermore, if Figure 3 As shown, the collecting mechanism 4 includes a collecting mounting frame 41, a collecting cup 42 and a collecting lifting drive assembly 43. The collecting mounting frame 41 is arranged on the frame and is located below the powder collecting box 1. The collecting cup 42 is arranged on the collecting mounting frame 41 and can be directly opposite to the discharge port of the powder collecting box 1. The collecting lifting drive assembly 43 is configured to drive the collecting mounting frame 41 to rise and fall so as to be close to or away from the powder collecting box 1. Preferably, the collecting cup 42 is detachably connected to the collecting mounting frame 41, so that the operator can install and replace the collecting cup 42 conveniently.

[0047] Before the screwing mechanism 3 starts working, the collection lifting drive assembly 43 first drives the collection mounting frame 41 and drives the collection cup 42 to move upward, so that the cup cover of the collection cup 42 is set at the discharge port of the powder collection box 1, and then the screwing mechanism 3 starts working, so that the PP particles can fall into the collection cup 42, preventing the PP particles from being blown away in the process of falling into the collection cup 42, causing environmental pollution and waste of PP particles. When the collection cup 42 is full of PP particles, the collection lifting drive assembly 43 drives the collection mounting frame 41 and drives the collection cup 42 to move downward, so that the collection cup 42 is away from the powder collection box 1, which is convenient for the operator to take away the collection cup 42 full of PP particles and put a new collection cup 42 in.

[0048] Specifically, a limiting slide groove is provided on the mounting frame 41, and a limiting ring is protruding at the cup mouth of the collecting cup 42. The collecting cup 42 can slide along the limiting slide groove, and the bottom of the limiting ring can abut against the upper surface of the mounting frame 41 to realize a detachable connection between the collecting cup 42 and the mounting frame 41.

[0049] Furthermore, in order to improve the collection efficiency, the number of the collection cups 42 is multiple, and the multiple collection cups 42 are arranged at intervals along the circumference of the collection mounting frame 41, and the discharge port of the powder collection box 1 can selectively face any collection cup 42. In this embodiment, the number of the collection cups 42 is two, and the two collection cups 42 are respectively arranged on both sides of the collection mounting frame 41. When the cup cover of one of the collection cups 42 is arranged at the discharge port of the powder collection box 1, the other collection cup 42 is horizontally away from the powder collection box 1 (such as Figure 1As shown), the operator can remove the collection cup 42 away from the powder collecting box 1 and then replace it with a new collection cup 42 without affecting the normal operation of the particle collection device.

[0050] Furthermore, the collecting mechanism 4 also includes a collecting rotating drive assembly 44, the output end of which is connected to the collecting mounting frame 41, for driving the collecting mounting frame 41 to rotate so that one of the collecting cups 42 is directly opposite to the discharge port of the powder collecting box 1.

[0051] Specifically, the collection lifting drive assembly 43 includes a second cylinder and a collection lifting plate, the output end of the second cylinder is connected to the collection lifting plate, and can drive the collection lifting plate to lift and lower, the collection rotation drive assembly 44 includes a second motor and a turntable, the second motor is arranged on the collection lifting plate, the output end of the second motor is connected to the turntable, and can drive the turntable to rotate, and the collection mounting frame 41 is arranged on the turntable. By arranging the collection lifting drive assembly 43 and the collection rotation drive assembly 44, the lifting and rotation of the collection mounting frame 41 and the collection cup 42 are realized.

[0052] Furthermore, a filter is provided in the collection cup 42. When the movable clamp 31 rubs the PP adhesive tape, the PP adhesive tape may be damaged, so some fragments of the PP adhesive tape may fall into the collection cup 42 together with the PP particles. A filter is provided in the collection cup 42, and the PP particles are filtered before falling into the bottom of the collection cup 42, so that the PP particles falling into the bottom of the collection cup 42 can be purer. Preferably, the filter is detachably connected to the collection cup 42. When collecting the PP particles at the bottom of the collection cup 42, the filter is first removed from the collection cup 42, and then the relatively pure PP particles in the collection cup 42 are transferred to the collection box. Specifically, an annular groove is provided at the edge of the filter, and the annular groove can be snapped onto the edge of the mouth of the collection cup 42, thereby realizing a detachable connection between the filter and the collection cup 42.

[0053] Furthermore, in order to improve the efficiency of PP particles passing through the filter, the collection mechanism 4 also includes a vibration assembly 45, which is configured to drive the collection cup 42 to vibrate. Specifically, the vibration assembly 45 includes a plurality of vibration cylinders arranged on a frame, and when the cup cover of the collection cup 42 is arranged at the discharge port of the powder collection box 1, the collection mounting frame 41 is directly opposite to the output ends of the plurality of vibration cylinders, and through the telescopic action of the output ends of the vibration cylinders, the output ends of the vibration cylinders continuously collide with the collection mounting frame 41, thereby driving the vibration of the collection cup 42, so that the PP particles can quickly pass through the filter.

[0054] Furthermore, if Figure 4 As shown, the particle collection device further includes a waste collection box 5, which is used to collect the PP adhesive tape from which the PP particles have fallen.

[0055] Furthermore, the fixed clamping mechanism 2 includes a second linear drive member 21 and a fixed jaw 22, the fixed jaw 22 can clamp one end of the PP adhesive tape, and the output end of the second linear drive member 21 is connected to the fixed jaw 22, which is used to drive the fixed jaw 22 to move between the powder collection box 1 and the waste collection box 5. The second linear drive member 21 is specifically a third cylinder. In this embodiment, the third cylinder is arranged on the frame, and the fixed end of the third cylinder and the fixed jaw 22 are respectively located on both sides of the waste collection box 5, the fixed jaw 22 is located on the side close to the powder collection box 1, and the fixed end of the third cylinder is located on the side away from the powder collection box 1. The output end of the third cylinder can pass through the waste collection box 5 and connect to the fixed jaw 22, and can drive the fixed jaw 22 to transfer between the powder collection box 1 and the waste collection box 5, so that the PP adhesive tape that has dropped all the PP particles is collected in the waste collection box 5, so as to realize the recycling of the PP adhesive tape.

[0056] Specifically, when all the PP particles on the PP tape in the powder collection box 1 have fallen off, the movable jaw 31 releases the PP tape, the fixed jaw 22 clamps one end of the PP tape, and the second linear drive member 21 drives the fixed jaw 22 to move into the waste collection box 5, and then the fixed jaw 22 releases the PP tape to allow it to fall into the waste collection box 5.

[0057] It is understandable that the specific structures of the movable clamping jaw 31 and the fixed clamping jaw 22 are all prior arts and are not described in detail in this application. Any clamping jaw structure that can clamp the PP adhesive tape can be adopted.

[0058] Combine the following Figure 1-Figure 4 Briefly describe the working process of the particle collection device:

[0059] (1) The operator puts the PP adhesive tape into the powder collecting box 1 from the feed port 11, and the second linear drive member 21 drives the fixed clamping claw 22 to extend into the powder collecting box 1 so that the fixed clamping claw 22 clamps one end of the PP adhesive tape;

[0060] (2) The first linear driving member 34 drives the movable clamping jaw 31 to move toward the fixed clamping jaw 22, so that the movable clamping jaw 31 clamps the other end of the PP adhesive tape;

[0061] (3) The collection rotation drive assembly 44 drives the collection mounting frame 41 to rotate so that the cup mouth of one of the collection cups 42 is directly opposite to the discharge port of the powder collection box 1, and then the collection lifting drive assembly 43 drives the collection mounting frame 41 to move upward so that the cup mouth cover of the collection cup 42 is set at the discharge port of the powder collection box 1;

[0062] (4) The first linear drive member 34 continues to drive the movable jaw 31 to move toward the fixed jaw 22 at a preset speed, and the rotary drive member 32 is screwed to drive the movable jaw 31 to reciprocate at a small angle. At the same time, the movable jaw 32 is continuously opened and closed on both sides of the PP adhesive tape, so that the PP particles fall from the PP adhesive tape to the bottom of the powder collecting box 1 and fall into the collecting cup 42 from the discharge port;

[0063] (5) When all the PP particles on the PP adhesive tape have fallen off, the movable jaw 31 releases the PP adhesive tape, and the second linear drive member 21 drives the fixed jaw 22 to extend into the waste collection box 5, and then the fixed jaw 22 releases the PP adhesive tape, so that the PP adhesive tape falls into the waste collection box 5;

[0064] (6) When the above-mentioned collecting cup 42 is filled with PP particles, the collecting lifting drive assembly 43 drives the collecting mounting frame 41 to move downward so that the cup mouth of the collecting cup 42 is away from the discharge port of the powder collecting box 1, and the collecting rotating drive assembly 44 drives the collecting mounting frame 41 to rotate so that the cup mouth of another collecting cup 42 is opposite to the discharge port of the powder collecting box 1, and then the collecting lifting drive assembly 43 drives the collecting mounting frame 41 to move upward so that the cup mouth cover of the other collecting cup 42 is set at the discharge port of the powder collecting box 1. At this time, the particle collecting device can continue to start, and the operator removes the collecting cup 42 filled with PP particles and replaces it with a new collecting cup 42.

[0065] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments.
