[0002] A hygiene product packaging machine is a device that automatically packages tissues into packaging bags.

[0003] Existing hygiene product packaging machines lack vacuum suction functionality for servo conveying of packaging bags. This poses a risk of displacement when the bags are laid flat on the conveyor belt during transport, especially in windy environments. Additionally, the current method of feeding the packaging belt from top to bottom results in uneven folding of the bag opening. All of these issues can lead to misalignment of the subsequent bag opening mechanism 5, preventing the bag opening from opening properly. To address these shortcomings, this invention proposes a hygiene product packaging machine with a vacuum suction bag conveyor belt. Utility Model Content

A vacuum suction box assembly is fitted between the middle of the second servo conveyor belt and the right side of the bottom surface of the bag guide frame.

[0006] A further improvement is that multiple small suction holes for bag openings are spaced apart on the right side frame of the bag guide frame, and the bag opening mechanism is vertically aligned with each small suction hole for bag openings. The second servo conveyor belt has multiple vacuum adsorption holes arrayed on its belt.

[0007] A further improvement is that the vacuum suction box assembly includes a first suction plate box, and an opening is provided in the middle of the right side of the first suction plate box, and a second suction plate box is connected to the opening. The top surface of the first suction plate box is provided with a plurality of first suction openings that are connected to the vacuum adsorption holes at intervals. The top surface of the second suction plate box is provided with a plurality of second suction openings that are connected to the bag mouth adsorption holes at intervals. A vacuum pump is connected to the right side of the first suction plate box through a suction hose.

[0008] A further improvement is that the bag-catching mechanism includes a support frame, on which synchronous belt conveyors and horizontal rails are arranged at horizontal intervals, and a drag block that is fixed to the synchronous belt conveyor and is pulled laterally is sleeved on the horizontal rail, and a bag-catching assembly is arranged vertically on the drag block.

[0009] A further improvement is that the bag-catching assembly includes a fixing plate, on which a pneumatic telescopic device is vertically arranged, and a longitudinal frame is longitudinally arranged at the lower end of the pneumatic telescopic device, on which multiple suction cup rods are vertically spaced.

[0010] The packaging bag feeding rack mechanism includes a lifting support, and two slide rails are vertically arranged at the left and right ends of the front side of the lifting support. A material rack is movably fitted between the two slide rails. A lead screw pusher is fitted at the middle of the front end of the material rack. A lead screw is threaded onto the lead screw pusher. A motor is driven to the lower end of the lead screw. An infrared sensor is provided on the top surface of the lifting support.

[0011] Further improvements are made to the fact that the pusher, the first servo conveyor belt, the anti-detachment pressing mechanism, the bag opening support mechanism, the bag opening opening mechanism, the heat sealing mechanism, the bag pressing and positioning mechanism, and the control panel are all existing technologies, and their structures and functions will not be described in detail here.

[0012] A further improvement is that the other end of the pneumatic telescopic device and each suction cup rod is connected to a vacuum pump via an air intake hose.

[0014] The beneficial effects of the utility model are: This utility model provides a hygiene product packaging machine with a vacuum suction bag conveyor belt. It comprises a vacuum conveyor belt mechanism and support consisting of a bag guide frame, a second servo conveyor belt, and a vacuum suction box assembly; a synchronous belt conveyor; a cross rail; a bag-grabbing mechanism and pusher consisting of a drag block and a bag-grabbing assembly; a first servo conveyor belt; an anti-detachment pressing mechanism; a bag opening support mechanism; a bag opening opening mechanism; a heat-sealing mechanism; a bag-pressing and positioning mechanism; and a packaging bag unloading rack mechanism, all mounted on a frame. This design creates a hygiene product packaging machine with a vacuum suction bag conveyor belt. The second servo conveyor belt of this utility model has a vacuum suction conveying function, servo-transporting the packaging bags forward. There will be no displacement or deviation issues. It also has a vacuum adsorption function that works in conjunction with the bag opening mechanism to open the bag opening. The bag grabbing mechanism uses a horizontal adsorption and dragging method to drag the packaging bags on the packaging bag feeding rack mechanism to the vacuum conveyor belt mechanism. During this process, due to the vacuum adsorption of the vacuum conveyor belt mechanism, the bag body will have a leveling process, so that the bag opening will not fold. This effectively solves the problems of bag feeding deviation and bag opening folding in the existing technology. In addition, the packaging bag feeding rack mechanism uses an infrared sensor in conjunction with a lead screw to push the packaging bag, so that the packaging bag can automatically rise and cooperate with the intermittent feeding of the bag grabbing mechanism, which is highly practical.

The bag positioning mechanism 10 has a bag feeding rack mechanism 11 on the right side of the bag grabbing mechanism 8. The front side of the bag grabbing mechanism 8 has a control panel 12. The pusher 2, the first servo conveyor belt 3, the anti-detachment pressing mechanism 4, the bag opening support mechanism 5, the bag opening opening mechanism 6, the vacuum conveyor belt mechanism 7, the bag grabbing mechanism 8, the heat sealing mechanism 9, the bag pressing and positioning mechanism 10, and the bag feeding rack mechanism 11 are electrically connected to the control panel 12. The vacuum conveyor belt mechanism 7 includes a bag guide frame 71, and a second servo conveyor belt 72 is horizontally aligned in the middle of the bag guide frame 71. A vacuum suction box assembly 73 is fitted between the middle of the second servo conveyor belt 72 and the right side of the bottom surface of the bag guide frame 71.

[0018] The bag guide frame 71 has multiple bag mouth adsorption holes 74 spaced apart on the right side frame. The bag opening mechanism 6 is vertically aligned with each bag mouth adsorption hole 74. The second servo conveyor belt 72 has multiple vacuum adsorption holes 721 arrayed on its belt.

[0019] The vacuum suction box assembly 73 includes a first suction plate box 731, and a through-hole 732 is opened in the middle of the right side of the first suction plate box 731, and a second suction plate box 733 is connected to the through-hole 732. The top surface of the first suction plate box 731 is provided with a plurality of first suction openings 734 that are connected to the vacuum adsorption holes 721 at intervals. The top surface of the second suction plate box 733 is provided with a plurality of second suction openings 735 that are connected to the bag mouth adsorption holes 74 at intervals. A vacuum pump 736 is connected to the right side of the first suction plate box 731 through a suction hose.

[0020] The bag-catching mechanism 8 includes a bracket 81, on which a synchronous belt conveyor 82 and a horizontal rail 83 are arranged at horizontal intervals. A drag block 84, which is fixed to the synchronous belt conveyor 82 and is pulled horizontally, is sleeved on the horizontal rail 83. A bag-catching assembly 85 is vertically arranged on the drag block 84.

[0021] The bag-catching assembly 85 includes a fixing plate 851, on which a pneumatic telescopic device 852 is vertically arranged, and a longitudinal frame 853 is longitudinally arranged at the lower end of the pneumatic telescopic device 852. Multiple suction cup rods 854 are vertically spaced on the longitudinal frame 853.

[0022] The packaging bag feeding rack mechanism 11 includes a lifting support 111, and two slide rails 112 are vertically arranged at the left and right ends of the front side of the lifting support 111. A material rack 113 is movably fitted between the two slide rails 112. A lead screw push seat 114 is fitted at the middle of the front end of the material rack 113. A lead screw 115 is threaded onto the lead screw push seat 114. A motor 116 is drivenly connected to the lower end of the lead screw 115. An infrared sensor 117 is provided on the top surface of the lifting support 111.

[0023] Working principle: In use, the bag-catching assembly 85 first pulls the packaging bags in the packaging bag feeding rack mechanism 11 to the rear end of the second servo conveyor belt 72 by horizontal pulling. The synchronous belt conveyor 82 then moves the drag block 84 servo left and right on the horizontal rail 83. The pneumatic telescopic device 852 on the bag-catching assembly 85 lifts and lowers each suction cup rod 854 to adsorb the tail of the packaging bag. This allows the packaging bag to be dragged horizontally to the tail of the second servo conveyor belt 72 with vacuum adsorption for flat feeding, preventing folding of the bag opening. Then, the vacuum adsorption holes 721 on the second servo conveyor belt 72 generate negative pressure adsorption under the action of the first suction plate box 73, making the second servo conveyor belt 72 more stable and preventing displacement problems when it forward servo transports the packaging bag to the bag opening adsorption hole 74.

[0024] Then, under the action of the second suction plate box 733, the negative pressure adsorption function is generated through the small adsorption hole 74 at the bag opening, and it works in conjunction with the bag opening mechanism 6 to open the bag opening. Then, the bag opening support mechanism 5 uses a left-right horizontal movement to open the cavity of the packaging bag, so that the pusher 2 can push the paper towel that is flexibly pressed between the anti-detachment pressing mechanism 4 and the first servo conveyor belt 3 to the left into the cavity of the packaging bag. At the same time, the packaging bag containing the paper towel is pushed to the bottom of the heat sealing mechanism 9. Then, the heat sealing mechanism 9 heat seals the bag opening and trims the edges to complete the packaging of the sanitary products.

[0025] Additionally, when the bag-catching assembly 85 catches a packaging bag, the motor 116 on the packaging bag feeding rack mechanism 11 drives the lead screw 115 to rotate. Through the lead screw pusher 114, the feeding rack 113 is pushed up between the two slide rails 112, so that the infrared sensor 117 can sense the packaging bag on the feeding rack 113. When the infrared sensor 117 senses a packaging bag on the top surface, the motor 116 stops, thereby ensuring that the bag-catching assembly 85 can continue to catch bags.
