The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] like Figures 1 to 6 As shown, this utility model provides a fruit packaging bag binding tool, including a fruit receiving platform 10. Two sets of bag opening positioning components 20 are spaced apart along the height direction above the fruit receiving platform 10, forming a binding and adhesive area 30 between the two sets of bag opening positioning components 20. The two sets of bag opening positioning components 20 can clamp the upper and lower ends of the fruit packaging bag opening so that the binding section of the fruit packaging bag opening is located within the binding and adhesive area 30. Adhesive tape components 40 for feeding adhesive tape are provided on the fruit receiving platform 10 and on both sides of the binding and adhesive area 30. A lifting and opening mechanism 50 is provided on the fruit receiving platform 10 and above the two sets of bag opening positioning components 20. Adhesive tape pressing and cutting components 60 that can cooperate with each other are respectively provided on the two opening and closing ends of the lifting and opening mechanism 50. The lifting and opening mechanism 50 can drive the two sets of adhesive tape pressing and cutting components 60 to move towards each other into the binding and adhesive area 30 so that the adhesive tape on the adhesive tape components 40 is adhered to the binding section of the fruit packaging bag opening.

[0028] See Figure 1In one specific embodiment of this application, each end of the fruit-receiving platform 10 is provided with a vertical pole 11. Two sets of positioning plates 21 are spaced apart along the height direction on the upper ends of the two sets of vertical poles 11. The binding and adhesive area 30 is located between the two sets of positioning plates 21. Multiple sets of fruit grooves 12 are provided on the fruit-receiving platform 10. Bag opening fixing holes 22 are provided at positions corresponding to the two sets of positioning plates 21 and the multiple sets of fruit grooves 12. Multiple sets of bag inlets 23 communicating with the corresponding bag opening fixing holes 22 are provided on one side of the positioning plate 21. The fruit grooves 12 are used to place fruit and prevent it from shifting during binding. Workers can place the bagged and weighed fruit bags on the fruit-receiving platform 10, and then bundle and fix the bag openings into the bag opening positioning assembly 20. The multiple fruit grooves 12 and multiple bag opening fixing holes 22 enable the binding of multiple bag openings with tape in a single operation, accelerating the packaging speed. In addition, using two sets of positioning plates 21 to fix the bag opening can ensure that the binding section is located within the adhesive area 30, avoiding misalignment when the tape is pasted.

[0029] Furthermore, to enhance the securing effect on the bag opening, all the bag opening fixing holes 22 are provided with elastic limiting pads 24. Multiple sets of slit grooves 25 are radially spaced on the elastic limiting pads 24, one set of which connects to the bag opening 23. The elastic limiting pads 24 are made of silicone, allowing the bundled bag openings to be engaged within the slit grooves 25. They possess significant friction, preventing the bag openings from slipping out during tape binding and accommodating bag openings of different sizes. In other embodiments, elastic clamps can be used instead of the bag opening fixing holes 22 to directly clamp and secure the bag opening.

[0030] See Figure 5 and Figure 6 Both sets of tape pressing and cutting assemblies 60 include a pressing plate 61, which is respectively installed on two opening and closing ends at the bottom of the lifting and opening mechanism 50. When the lifting and opening mechanism 50 lowers the pressing plate 61 to the positions on both sides of the bonding area 30, it then drives the two sets of pressing plates 61 to move towards each other inward into the bonding area 30, so that the pressing plate 61 can press and adhere the tape on both sides to the binding section at the opening of the fruit packaging bag.

[0031] Furthermore, one set of the pressing plates 61 has a front cutter 62 on its inner side, located on both sides of the bag opening fixing hole 22, and the other set of the pressing plates 61 has a cutting groove 63 on its inner side, corresponding to the front cutter 62. All the cutting grooves 63 have a rear cutter 64 that can cooperate with the front cutter 62. The front cutter 62 and the rear cutter 64 cut alternately, with the top surface of the front cutter 62 flush with the bottom surface of the cutting groove 63. The pressing plate 61 can complete the pressing and cutting of the tape in one operation, and the tape is cut while being pressed and fixed, preventing tape movement and ensuring a clean cut.

[0032] See Figure 5 In one specific embodiment of this application, the lifting and opening mechanism 50 includes a lifting seat 51 and two sets of opening and closing rods 52. A mounting frame 13 is provided on the fruit receiving platform 10 and above the bag opening positioning component 20. A lifting cylinder 53 is provided on the mounting frame 13. The lifting seat 51 is installed on the driving end of the lifting cylinder 53. An opening and closing groove 54 is provided at the bottom of the lifting seat 51. A bidirectional lead screw 55 is rotatably installed in the opening and closing groove 54. A rotary motor 56 with its driving end connected to one end of the bidirectional lead screw 55 is provided on the lifting seat 51. Lead screw nuts 57 are slidably installed on both ends of the bidirectional lead screw 55. The two sets of opening and closing rods 52 are respectively installed on the bottom of the two sets of lead screw nuts 57. The two sets of pressure plates 61 are respectively installed on the lower ends of the two sets of opening and closing rods 52. The lifting cylinder 53 is used to drive the pressing plate 61 to move up and down. This is a prior art technology. Before putting the bag in and pulling out the tape, the pressing plate 61 can be raised above the positioning plate 21 to prevent obstruction of the operation. After fixing the fruit bag opening and pulling out the tape on both sides, the pressing plate 61 can be lowered. Then, the two sets of pressing plates 61 are driven by the rotary motor 56 to move towards each other in the adhesive area 30 to press and cut the tape. This is repeated to perform the binding operation.

[0033] In addition, the function of the opening and closing rod 52 is to drive the pressure plate 61 to move in opposite directions to complete the pressing and cutting of the tape. In order to ensure that the pressure plate 61 can close smoothly, both sets of opening and closing rods 52 are provided with outward bending avoidance sections at the corresponding positions of the positioning plate 21 to prevent the opening and closing rods 52 from interfering with the positioning plate 21.

[0034] See Figure 3The tape assembly 40 includes two sets of film holders 41, which are respectively installed on both sides of one end of the fruit-receiving platform 10. Tape fixing clips are provided on both sides of the other end of the fruit-receiving platform 10. Each set of tape fixing clips includes clamping rods 43 installed on both sides of one end of the fruit-receiving platform 10, and each clamping rod 43 has a clamping groove 44 at its upper end. The tape assembly 40 also includes multiple sets of guide rods 45, which are respectively positioned between the film holders 41 and the bag opening positioning component 20, and between the tape fixing clips and the bag opening positioning component 20. The positions of the guide rods 45 can be adjusted and set according to specific circumstances. The film holders 41 and guide rods 45 guide the path of the tape, while the clamping grooves 44 are used to clamp and fix the end of the tape.

[0035] The specific operating procedure is as follows: Insert the bag opening filled with fruit into the elastic limiting pad 24 through the bag inlet 23 to secure the bag opening (see...). Figure 1 ); Pull the tape out from the film holder 41, pass it over the guide rod 45, and fix it in the clamping groove 44 (see Figure 2 The lifting cylinder 53 drives the pressure plate 61 to descend to the binding and bonding area 30 (see...). Figure 3 Then, the rotary motor 56 drives the bidirectional lead screw 55, causing the pressing plates 61 to move in opposite directions to press the tape onto both sides of the bag opening, while the cutter completes the cutting (see...). Figure 4 The mechanism resets, and the bundled packaging bag is removed.

[0036] This utility model discloses a fruit packaging bag binding tool. Through the cooperation of the bag opening positioning component 20 and the fruit receiving platform 10, it can fix the bag opening and accurately position the binding section within the binding and bonding area 30, facilitating subsequent tape binding. It also includes a tape pressing and cutting component 60 that integrates pressing and cutting functions. By driving the lifting and opening mechanism 50, the tape on both sides can be bonded to the binding section of the bag opening, simultaneously completing the pressing, binding, and cutting operations of the tape, which can reduce the amount of binding tape used. It can also be set with multiple binding positions, allowing multiple bag openings to be bound at the same time, greatly improving the efficiency of fruit packaging.

[0037] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of the technical solution of this utility model.
