The rubber connecting belt 41 is installed inside the cleaning belt 31. Rubber sliding shafts 42 are provided at both ends of the rubber connecting belt 41. The rubber sliding shaft 42 is used for sealing and sliding inside the limiting sliding groove 33. The outer surface of the rubber sliding shaft 42 is arranged with a sealing strip 43. A connecting block 44 is fixedly installed inside the rubber sliding shaft 42. The sealing strip 43 is used to increase the sealing effect of the rubber sliding shaft 42 in the limiting sliding groove 33. The upper surface of the rubber connecting belt 41 and the inner space of the cleaning belt 31 are sealed; The sealing movable plate 4 further comprises a limiting sleeve 46 and a connecting bead 45. The limiting sleeve 46 is fixedly installed inside the connecting block 44. The connecting bead 45 is provided at one end of the connecting block 44.

When the liquid guide tube 48 is located at the lower end of the cleaning belt 31, it provides a liquid transport function; Elastic telescopic rods 10 are installed on both sides of the inner walls of the negative pressure belt 71 and the cleaning belt 31 . The elastic telescopic rods 10 are used to provide expansion and contraction compensation for the negative pressure belt 71 and the cleaning belt 31 .

[0032] When in use, the plastic product needs to be placed on the upper surface of one end of the equipment frame 1, and the plastic product is brought to the upper surface of the cleaning belt 31 and the negative pressure belt 71 by the rotation of the downward pressure belt 16, and continues to move, and the plastic product is driven to be pressed down by the downward pressure of the limit plate 17; according to Figure 10 As shown, by the movement of the downward pressure belt 16 and the provision of downward pressure, the upper surfaces of the cleaning belt 31 and the negative pressure belt 71 are brought closer to the lower surface of the plastic product. At this time, the first spring 58 provides a lifting force to push the lifting rod 22 upward, and then the lifting rod 22 pushes the negative pressure belt 71 and the cleaning belt 31 up, and forms a reverse force with the downward pressure of the plastic product, so that the upper surfaces of the cleaning belt 31 and the negative pressure belt 71 adapt to the grooves on the lower surface of the plastic product, and automatically fit the lower surface of the plastic product according to the cross-sectional shape of the plastic product, so that the negative pressure belt 71 and the cleaning belt 31 can change their own shapes according to the shape of the plastic product and fit with it to complete the contact state; The cleaning liquid is connected to the conveying device through the liquid guide tube 48 to convey the cleaning liquid to the upper surface space of the rubber connecting belt 41. At this time, the sponge 83 is located in the shrink cover 84. Through the material of the sponge 83, when the cleaning liquid contacts the sponge 83, it will be adsorbed by the sponge 83. When the cleaning belt 31 rises and contacts the lower surface of the plastic part, it will squeeze the shrink cover 84 and squeeze out the cleaning liquid inside the sponge 83 and flow to the inside of the surrounding bristles 82. There are also pores on the side of the shrink cover 84, and the cleaning liquid can also flow out from the side of the shrink cover 84 through these pores. Finally, the whole rotary disk 81 is driven by the cleaning belt 31, so that the bristles 82 contact and clean the lower surface of the plastic product. At this time, the cleaning belt 31 slides horizontally on the upper surface of the supporting roller 25. While sliding, the gear 97 at the bottom meshes with the gear of the driving rack 98 to provide a rotational power for the rotary disk 81. The sliding of the cleaning belt 31 provides the bristles 82 with a friction cleaning action on the plastic product, thereby increasing the rotation of the rotary disk 81, increasing the diversity of the friction cleaning action of the bristles 82, and improving the cleaning effect on the plastic product. At the same time, the rotation of the rotary disk 81 can make the limiting arc edge 89 gather the cleaning liquid to the axis of the rotary disk 81. At the same time, the spiral guide tube 80 can realize the scooping action, and send the cleaning liquid along the inside of the spiral guide tube 80 into the inside of the spiral groove 87 through the rotation force, and finally fall into the inside of the sponge 83, thereby increasing the amount of cleaning liquid discharged into the inside of the sponge 83, avoiding the difficulty of the cleaning liquid being absorbed by the upper part, resulting in insufficient absorption of liquid. When the plastic product is attached to the upper surface of the negative pressure belt 71 and the cleaning belt 31, the plastic product slides on the upper surface of the negative pressure belt 71 and the cleaning belt 31 through the continuous pressing of the lower pressure belt 16. When one end of the plastic product in the forward direction is pressed on the upper surface of the first cleaning belt 31, the cleaning belt 31 and the negative pressure belt 71 are linked by the traction belt 26. When the first cleaning belt 31 is pressed down, the subsequent cleaning belt 31 or the negative pressure belt 71 will be pulled down by the traction belt 26. As the plastic product moves, the end of the plastic product will press the traction belt 26 downward, so that the plastic product moves along the traction belt 26 to the upper surface of the next cleaning belt 31 or the negative pressure belt 71, completing the sliding effect of the plastic product when it is located on the upper surface of the cleaning belt 31 and the negative pressure belt 71. The device utilizes the ductility of the cleaning belt 31 so that when it is raised, it contacts the lower surface of the plastic product and changes its own structure according to its shape and structure to fit it; And through the action of the cleaning rack 8, it is possible to provide the function of cleaning liquid when cleaning plastic products, and through the sliding of the cleaning belt 31, on the basis of providing the bristles 82 with the friction cleaning action for the plastic products, increase the rotation of the turntable 81, increase the diversity of the friction cleaning action of the bristles 82, and improve the cleaning effect of the plastic products. Compared with the conventional structure, the convenience of cleaning is greatly increased.

The bottom surface of the inner wall of the negative pressure suction frame 61 is provided with an upper plate 64, the lower surface of the upper plate 64 is fixedly provided with a lower plate 65 located in the negative pressure suction frame 61, and the lower surface of the lower plate 65 is also provided with a top open cross bar 66 located on the inner wall of the negative pressure suction frame 61; The lower surface of the upper pasting plate 64 is used to seal and fit with the upper surface of the lower pasting plate 65; Second springs 67 are installed on both sides of the negative pressure suction frame 61, and the second springs 67 are used to provide a lifting force for the negative pressure suction frame 61; When the liquid guiding tube 48 is located at the lower end of the negative pressure belt 71, negative pressure suction is provided.

[0034] After the bristles 82 complete the cleaning task, residual cleaning liquid will be attached to the outer surface of the plastic paper product, which needs to be removed, otherwise it will affect the use of the product; When the plastic product is attached to the upper surface of the cleaning belt 31 and the negative pressure belt 71, the liquid guide tube 48 below the negative pressure belt 71 is connected to the negative pressure device to provide negative pressure suction for the space above the rubber connecting belt 41. When the upper surface of the absorbent cotton 62 is attached to the plastic product, the material properties of the absorbent cotton 62 will absorb the cleaning liquid after contact, and at the same time, the negative pressure suction frame 61 will be pressed down. After being pressed down to the position of the top cross bar 66, the top cross bar 66 will lift the upper plate 64 to release the sealing state between the upper plate 64 and the lower plate 65, so that the negative pressure force can absorb the absorbent cotton 62, and at the same time, the air vents 63 are used to vent the surface of the plastic product. The suction is performed and the cleaning liquid is absorbed into the inside, so that the negative pressure belt 71 drives the absorbent cotton 62 to move together while moving horizontally, and realizes the scraping action, and the material characteristics of the absorbent cotton 62 are used to directly absorb the cleaning liquid, and then the negative pressure suction provided by the liquid guide tube 48 is used to suck the outer surface of the plastic product through the air vent 63. The two operation modes cooperate with each other to directly remove the residual cleaning liquid, and the negative pressure suction can only be triggered when the negative pressure suction frame 61 is subjected to downward pressure, and at other times, it remains in a closed state. This operation can ensure the strength of the negative pressure suction, which is only in an open state during operation; Through the action of the negative pressure suction member 6, the processing operation of the cleaning liquid can be realized. The cleaning liquid is first adsorbed by the absorbent cotton 62, and then the absorbent cotton 62 is pressed downwardly and contacted with the plastic product to release the closed state of the upper plate 64 and the lower plate 65, thereby realizing the effect of negative pressure suction. While sucking the cleaning liquid, the moisture inside the absorbent cotton 62 can also be sucked together to complete the suction operation of the cleaning liquid.

The reduction box 96 is used for gear meshing transmission with the drive shaft 95. A cleaning liquid delivery pump 11 is installed at one end of the equipment rack 1, a negative pressure pump 12 is installed on one side of the cleaning liquid delivery pump 11, a liquid delivery pipe 13 is connected to one end of the cleaning liquid delivery pump 11, and a negative pressure pipe 14 is connected to one end of the negative pressure pump 12. Both the liquid delivery pipe 13 and the negative pressure pipe 14 extend to the interior of the equipment rack 1; A forked connecting tube 15 is arranged at one end of the liquid supply tube 13 and the negative pressure tube 14, and the forked connecting tube 15 is fixed to each built-in truss 20. The liquid supply tube 13 and the negative pressure tube 14 are each arranged with a group of forked connecting tubes 15, and each group of forked connecting tubes 15 is correspondingly connected to the liquid guide tube 48. One end of the liquid supply tube 13 is connected to the liquid guide tube 48 at the lower end of the cleaning belt 31, and one end of the negative pressure tube 14 is connected to the liquid guide tube 48 at the lower end of the negative pressure belt 71.

[0036] When the cleaning belt 31 and the negative pressure belt 71 rebound, if the rebound speed is too fast, it will cause the surface of the next plastic product to be bumped, affecting the surface quality; The negative pressure pump 12 provides negative pressure suction, and is connected to the liquid guide tube 48 under each negative pressure belt 71 through the bifurcated connecting tube 15 at one end of the negative pressure tube 14. According to the same steps, the bifurcated connecting tube 15 at one end of the liquid delivery tube 13 is connected to the liquid guide tube 48 under each cleaning belt 31. A plug-in shaft is provided at one end of the friction end 53, and the plug-in shaft is used to increase the stability of the friction end 53. During rebound, the first spring 58 provides elastic thrust, the lifting rod 22 rises, and then forms relative motion with the middle vertical rod 51, and at the same time, the friction end 53 and the inclined surface edge 52 are rubbed, and the inclined surface edge 52 makes the lifting rod 22 rebound more upward, the friction force between the friction end 53 and the inclined surface edge 52 is greater, and the resistance is greater. This operation can increase the resistance of the lifting rod 22 during the initial rebound, and avoid the situation that the friction resistance between the friction end 53 and the inclined surface edge 52 is small during the initial rebound, and the rebound force cannot be limited, and the speed of the lifting rod 22 when it is raised is slowed down to avoid the possibility of collision with plastic products, and the built-in cavity 56 is provided with air holes, so that the gas on both sides of the built-in cavity 56 can flow normally; Through the linkage structure between the reduction box 96 and the lower plate 65, during operation, the friction shaft 93 is driven to operate through the driving shaft 95, and the two friction shafts 93 clamp the cleaning belt 31 or the negative pressure belt 71 therein, and provide sliding power support for the cleaning belt 31 and the negative pressure belt 71. At the same time, when the plastic product is subjected to a downward pressure force, the cleaning belt 31 and the negative pressure belt 71 are embedded in their internal grooves, and the bottoms of the cleaning belt 31 and the negative pressure belt 71 are compensated and retracted, and at the same time, the outer shell 91 is driven to rise, and the position is limited by the limiting side frame 92, so that the outer shell 91 can only be raised according to the position of the limiting side frame 92, so that the power output to the cleaning belt 31 and the negative pressure belt 71 can be maintained while it is rising; The cleaning belt 31 and the negative pressure belt 71 are normally in a rectangular state, and the total length of the two is unchanged. When the upper surfaces of the two are in contact with the lower surface of the plastic product, if there is a pit on the lower surface of the plastic product, a height difference will be generated when the cleaning belt 31 and the negative pressure belt 71 are attached to it. The appearance of the height difference will increase the use length of the cleaning belt 31 and the negative pressure belt 71. At this time, the lower ends of the cleaning belt 31 and the negative pressure belt 71 will be pulled, and the lower ends of the cleaning belt 31 and the negative pressure belt 71 will be pulled upward to compensate for the required length when the upper part is attached to the plastic product, and the elastic telescopic rod 10 will be retracted, and the outer shell 91 will be The cleaning belt 31 and the negative pressure belt 71 are clamped therein. When the cleaning belt 31 and the lower end of the negative pressure belt 71 are contracted, 91 will be driven to rise together. It should be noted that cross bars are provided at the two corners of the upper cleaning belt 31 to support and position the corners of the cleaning belt 31. Secondly, only the rubber connecting belt 41 at the top in a horizontal state is provided with a driving rack 98, and the rubber connecting belt 41 and the driving rack 98 are both made of rubber and have a certain elasticity. At the same time, the bottom gear 97 has a small diameter, and when the rubber connecting belt 41 and the driving rack 98 at the top in a horizontal state are bent by the shape of the plastic product (such as Fig.10 ), at this time, because the diameter of the bottom gear 97 is small, and the bending angles of the rubber connecting belt 41 and the driving rack 98 are relatively small, the driving rack 98 can also produce a certain deformation, so that the bottom gear 97 can pass normally, effectively avoiding the situation of being stuck; and located in Figure 6 The rubber connecting belt 41 at the corner of the middle connecting block 44 is not provided with a driving rack 98, and the subsequent reciprocating motion of the friction shaft 93 drives the cleaning belt 31 to reciprocate on the rubber connecting belt 41 to achieve the polishing of the plastic product. At the same time, in order to avoid the left and right deviation of the polished part on the cleaning belt 31, technical personnel in this field can use a clamping and positioning device to position the plastic product during the polishing process. The clamping and positioning device is a prior art and can be a clamping robot arm. Personnel in this technical field can select it according to actual needs.
