[0002] A PET bottle refers to a bottle containing a plastic material called polyethylene terephthalate, or simply PET for short. It is a polymer produced by the combination of terephthalic acid and ethylene glycol. PET plastics are lightweight, highly transparent, impact-resistant and not easily broken, and can also prevent carbon dioxide gas from escaping, keeping the soda fizzy.

[0003] For this reason, Chinese Patent Publication No. 202022560100.3 discloses an automatic PET bottle cap ring cutting machine. Through the structural design between the disk motor and the rotating hollow disk, the disk motor can drive the rotating hollow disk to rotate. Then, through the regular bottle cap round holes and irregular bottle cap round holes designed on the rotating hollow disk, it can screen the bottle caps poured onto the rotating hollow disk once. Through the structural design between the regular bottle cap discharge port and the irregular bottle cap discharge port designed on the partition plate, the bottle caps after screening at the irregular bottle cap discharge port can be poured into the conduit. Through the structural design between the two conduits and the recycling box and the raw material conveying component respectively, the raw material conveying component can introduce the bottle caps meeting the specifications into the raw material conveying component, and the bottle caps not meeting the specifications into the recycling box, so that the automatic PET bottle cap ring cutting machine achieves the purpose of automatically screening the bottle caps;

[0004] Although this patent can facilitate the screening of bottle caps, the method of transporting bottle caps using a conduit is prone to causing bottle caps to block inside the conduit, resulting in blockage problems during the operation of the device. Summary of the Utility Model

[0005] Aiming at the problem that although the existing technology can facilitate the screening of bottle caps, the method of transporting bottle caps using a conduit is prone to causing bottle caps to block inside the conduit, resulting in blockage problems during the operation of the device, the utility model proposes the following technical solutions:

[0006] An automatic PET bottle cap ring cutting machine, comprising: a ring cutting part, a conveying part is arranged on one side of the ring cutting part, a screening part is arranged on one side of the conveying part, and a blockage pressurizing structure is fixedly installed at the top end of the inner wall of the screening part;

[0007] The blockage pressurizing structure includes an electric telescopic rod fixedly installed at the top end of the inner wall of the screening part. The output shaft of the electric telescopic rod is fixedly installed with an end cover. A fan is embedded in the end cover, and a filter screen is installed at the top of the fan through screws.

[0008] Preferably, four manual telescopic rods are equidistantly embedded and installed at the bottom of the outer surface of the end cover. A circular ring is fixedly installed between the bottom ends of the four manual telescopic rods, and a sealing ring is clamped and installed on the inner wall of the circular ring.

[0009] Preferably, the screening part is composed of a screening frame, a screening disc, a driving motor, and a conduit.

[0010] Preferably, the outer diameter and inner diameter of the end cover are equal to the outer diameter and inner diameter of the screening frame, and the inner diameter of the circular ring is equal to the outer diameter of the end cover.

[0011] Preferably, a connection and positioning structure is fixedly installed at one end of the screening part. The connection and positioning structure includes a fixed column fixedly installed on one end face of the screening part, and clamping strips are symmetrically and slidably connected inside the fixed column.

[0012] Preferably, a positioning rod is sleeved outside the clamping strip. A bidirectional threaded rod is rotatably connected inside the positioning rod. The bidirectional threaded rod is threadedly connected to the positioning rod, and a rotating sleeve is welded to one end face of the bidirectional threaded rod.

[0013] The beneficial effects of the present utility model are as follows:

[0014] (1) The flowing gas pressurizes the inside of the screening frame. The gas pressure after pressurization pushes the bottle cap to flow inside the conduit, preventing the bottle cap from being blocked inside the conduit and causing the device to malfunction and resulting in a shutdown problem.

[0015] (2) Fix the cutting ring part and the screening part, making the cutting ring part and the screening part form an integral body, thereby preventing the problem that the distance between the two changes due to the vibration of one of the parts, and further facilitating the operation of the overall equipment.

[0025] Embodiment 1

[0026] The present utility model provides an automatic PET bottle cap ring cutting machine, as Figures 1-5 shown, which includes: a ring cutting part 1, a conveying part 2 is arranged on one side of the ring cutting part 1, a screening part 3 is arranged on one side of the conveying part 2, and a blocking and pressurizing structure 4 is fixedly installed at the top end of the inner wall of the screening part 3;

[0027] The blocking and pressurizing structure 4 includes an electric telescopic rod 41 fixedly installed at the top end of the inner wall of the screening part 3. The input end of the electric telescopic rod 41 is electrically connected to the output end of an external power source. The output shaft of the electric telescopic rod 41 is fixedly installed with an end cover 42. A fan 43 is embedded in the end cover 42. The input end of the fan 43 is electrically connected to the output end of an external power source. A filter screen 44 is installed at the top of the fan 43 by screws.

[0028] As Figure 3 and Figure 4 shown, four manual telescopic rods 45 are equidistantly embedded and installed at the bottom of the outer surface of the end cover 42. A ring 46 is fixedly installed between the bottom ends of the four manual telescopic rods 45. A sealing ring 47 is clamped and installed on the inner wall of the ring 46. The screening part 3 is composed of a screening frame, a screening disc, a driving motor and a conduit. The outer diameter and inner diameter of the end cover 42 are equal to the outer diameter and inner diameter of the screening frame. The inner diameter of the ring 46 is equal to the outer diameter of the end cover 42, which is used to increase the sealing performance at the connection between the end cover 42 and the screening frame, prevent gas leakage, so that the gas presses the bottle caps inside the conduit, and further prevent the problem of bottle caps accumulating inside the conduit.

[0029] As Figure 1 and Figure 5As shown, a connection and positioning structure 5 is fixedly installed at one end of the screening part 3. The connection and positioning structure 5 includes a fixed column 54 fixedly installed on one end face of the screening part 3. Inside the fixed column 54, clamping strips 53 are symmetrically and slidably connected. A positioning rod 51 is sleeved outside the clamping strips 53. Inside the positioning rod 51, a bidirectional threaded rod 52 is rotatably connected. The bidirectional threaded rod 52 is threadedly connected to the positioning rod 51. A rotating sleeve 55 is welded to one end face of the bidirectional threaded rod 52, which is used for the connection and fixation between the ring cutting part 1 and the screening part 3, making the connection between the ring cutting part 1 and the screening part 3 more stable and preventing the separation problem between the ring cutting part 1 and the screening part 3 from occurring.

[0030] Working principle: During the actual use of this device, the user installs the ring cutting part 1, the conveying part 2, and the screening part 3 at the pre-determined positions. Then, the user drives the bidirectional threaded rod 52 to rotate through the rotating sleeve 55. When the bidirectional threaded rod 52 rotates, it drives the clamping strips 53 to move, so that the clamping strips 53 enter the inside of the positioning rod 51, thus completing the fixation between the ring cutting part 1 and the screening part 3, making the ring cutting part 1 and the screening part 3 form an integral body, and further preventing the problem that the distance between the two changes due to the vibration of one part, which further facilitates the operation of the overall device.

[0031] Since after the screening part 3 is used, some bottle caps are blocked inside the conduit due to insufficient pressure. At this time, the user drives the electric telescopic rod 41 to operate. When the electric telescopic rod 41 operates, it drives the end cover 42 to enter the top of the screening frame of the screening part 3. Then, the user pulls the ring 46, and the ring 46 drives the manual telescopic rod 45 to stretch, and at this time, it drives the sealing ring 47 to enter the connection between the end cover 42 and the screening frame. Then, the fan 43 is started. When the fan 43 operates, it drives the gas to be filtered along the filter net 44. The filtered gas enters the inside of the screening frame. At this time, the flowing gas pressurizes the inside of the screening frame, and the pressure of the pressurized gas pushes the bottle cap to flow inside the conduit, preventing the bottle cap from being blocked inside the conduit and causing the device to malfunction and stop working.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
