A spring is fixedly connected to the ratchet, one end of the spring is fixedly connected to the spur gear, and the ratchet is fixedly sleeved on the drive shaft. The ratchet and the ratchet correspond to and are adapted to each other.

[0010] As a further improvement of this utility model: the receiving box is symmetrically equipped with wheels on its side and a push handle is installed on the receiving box. The receiving box can be pushed and moved by the cooperation of the wheels and the push handle.

[0011] As a further embodiment of this utility model: an outer connecting groove is fixedly connected between the legs of the cooling conveying mechanism, and an inner connecting groove is connected to the receiving box corresponding to the outer connecting groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model uses an electric push rod to drive the blade holder to rise and fall, thereby cutting plastic packaging boxes through the cooperation of the cutting blade and the blade groove. At the same time, the blade holder drives the toothed plate to move up and down reciprocally. When the toothed plate descends, it drives the spur gear to rotate forward. At this time, under the action of the adjustable ratchet structure, the spur gear drives the drive shaft to rotate. When the toothed plate rises, the spur gear rotates in the opposite direction without load and does not drive the drive shaft to rotate. Thus, the first bevel gear and the second bevel gear drive the threaded rod to rotate, which in turn drives the placement plate to descend through the threaded assembly. In this way, each cut plastic packaging box is gradually supported by the placement plate and the plastic packaging boxes on it, preventing them from falling directly and causing unevenness.

[0016] 2. This utility model controls the ratchet teeth that cooperate with the ratchet by moving the toggle block, thereby controlling the rotation direction of the ratchet. This allows the toothed plate to drive the spur gear to rotate in the opposite direction, thereby controlling the lifting of the placement tray and facilitating the removal of plastic packaging boxes located in the receiving box.

[0017] 3. In this utility model, the opening of the outer connecting groove is set outwards and the opening of the inner connecting groove is set inwards, which facilitates insertion and alignment. The clamping rod slides up in the groove by pressing the inclined plate until the groove is aligned. When the groove is aligned, the clamping rod falls into the groove to form a limit, forming a quick alignment connection limit effect, which facilitates the combination, alignment and fixation of the receiving box and the cooling conveying mechanism.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5In this embodiment of the present invention, a plastic packaging box blister forming processing receiving mechanism includes a receiving box 2 disposed outside a cooling conveying mechanism 1. A mounting frame 3 is fixedly connected to the top of the receiving box 2 near the cooling conveying mechanism 1. A blade holder 4 is slidably connected to the inner side of the mounting frame 3. A cutting blade 5 is fixedly connected to the bottom surface of the blade holder 4. A blade groove 6 is provided on the mounting frame 3 corresponding to the cutting blade 5. An electric push rod 7 is symmetrically fixedly mounted on the top surface of the mounting frame 3. The electric push rod 7 is externally connected to a power supply and a switch. The telescopic end of the electric push rod 7 slides through the mounting frame 3 and is fixedly connected to the blade holder 4. Two toothed plates 8 are symmetrically fixedly connected to the bottom surface of the blade holder 4. The toothed plates 8 slide through the middle crossbeam of the mounting frame 3 and are meshed with a spur gear 9. A sliding groove for the toothed plates 8 to slide through and slide on the middle crossbeam of the mounting frame 3 is provided. The toothed plates 8 slide against the inner wall of the receiving box 2. The spur gear 9 is rotatably connected to the inner wall of the receiving box 2. A drive mechanism is rotatably mounted inside the receiving box 2 corresponding to the axis of the spur gear 9. Shaft 10, spur gear 9 has a cavity corresponding to drive shaft 10, and an adjustable ratchet structure 11 is provided between spur gear 9 and drive shaft 10. The adjustable ratchet structure 11 can be adjusted in the forward and reverse directions. Two first bevel gears 12 are fixedly connected to drive shaft 10. The bottom of the first bevel gears 12 is meshed with a second bevel gear 13. The second bevel gear 13 is fixedly connected to the top of threaded rod 14. Threaded rod 14 is rotatably connected to the inside of receiving box 2. Isolation plates 15 are symmetrically fixedly connected to the inside of receiving box 2. The isolation plates 15 isolate the transmission components on both sides. Isolation plates 15 are set on the outside of threaded rod 14 and drive shaft 10. Threaded fittings 16 are threadedly connected to threaded rod 14. Threaded fittings 16 move through isolation plates 15. Isolation plates 15 have slots for threaded fittings 16 to pass through and slide up and down. The ends of threaded fittings 16 are fixedly connected to a placement plate 17. The spacing between placement plate 17 and isolation plate 15 is adapted.

[0026] The electric push rod 7 drives the blade holder 4 to rise and fall, thereby cutting the plastic packaging box through the cooperation of the cutting blade 5 and the blade groove 6. At the same time, the blade holder 4 drives the toothed plate 8 to move up and down. When the toothed plate 8 falls, it drives the spur gear 9 to rotate forward. At this time, under the action of the adjustable ratchet structure 11, the spur gear 9 drives the drive shaft 10 to rotate. When the toothed plate 8 rises, the spur gear 9 rotates in the opposite direction without load and does not drive the drive shaft 10 to rotate. Thus, the first bevel gear 12 and the second bevel gear 13 drive the threaded rod 14 to rotate, thereby driving the placement plate 17 to fall through the threaded assembly 16. Thus, each cut plastic packaging box is gradually supported by the placement plate 17 and the plastic packaging box on it, and there will be no situation where it falls directly and causes an uneven situation.

[0027] The adjustable ratchet structure 11 includes a ratchet 18, symmetrically arranged ratchet teeth 19, and a toggle block 20.

[0028] The ratchet 19 is symmetrically and rotatably mounted on the side wall of the spur gear 9. The actuating block 20 is disposed between the ratchet 19 and rotatably connected to the spur gear 9. The actuating block 20 is adapted to the ratchet 19. When the actuating block 20 is in contact with one side of the ratchet 19, it can push the ratchet 19 on the other side away, thereby forming an adjustment effect. A spring 21 is fixedly connected to the ratchet 19. One end of the spring 21 is fixedly connected to the spur gear 9. The ratchet 18 is fixedly sleeved on the drive shaft 10. The ratchet 19 and the ratchet 18 correspond to and are adapted to each other.

[0029] By controlling the ratchet 19 that engages with the ratchet 18 through the toggle block 20, the rotational direction of the ratchet 18 can be controlled. This allows the spur gear 9 to be driven in the opposite direction through the toothed plate 8, thereby driving the drive shaft 10 to rotate and controlling the placement tray 17 to rise, making it easier to remove the plastic packaging box located in the receiving box 2.

[0030] The receiving box 2 is symmetrically equipped with wheels 22 on its side, and a push handle 23 is installed on the receiving box 2. The receiving box 2 can be pushed and transferred by the cooperation of the wheels 22 and the push handle 23.

[0031] An outer connecting groove 24 is fixedly connected between the legs of the cooling conveying mechanism 1. An inner connecting groove 25 is connected to the receiving box 2 at the corresponding position of the outer connecting groove 24. The opening of the outer connecting groove 24 is set outwards, and the opening of the inner connecting groove 25 is set inwards.

[0032] The opening of the inner connecting groove 25 is provided with a connected ramp 26 and a slot 27. The outer connecting groove 24 is provided with a sliding groove 28 that is adapted to the ramp 26 at the slot 27. A locking rod 29 is movably connected in the sliding groove 28. The locking rod 29 is adapted to the slot 27 and can be lifted up along the ramp 26.

[0033] The opening of the outer connecting groove 24 is set outwards, and the opening of the inner connecting groove 25 is set inwards, so as to facilitate insertion and alignment. The clamping rod 29 is pressed by the ramp 26 and slides upwards in the slide groove 28 until the clamping groove 27 corresponds. When the clamping rod 29 falls into the clamping groove 27, it forms a limit, forming a quick alignment connection limit effect, which facilitates the combination, alignment and fixation of the receiving box 2 and the cooling conveying mechanism 1.

[0034] Guide rods 30 are fixedly connected at equal intervals on the inner connecting groove 25. Guide sleeves 31 that are adapted to the guide rods 30 are slidably sleeved on the outer side of the guide rods 30. The guide sleeves 31 are fixedly connected to the bottom surface of the receiving box 2. The guide rods 30 are provided with scale lines. The end of the guide sleeves 31 is threadedly connected with a hand-tightening bolt 32. The hand-tightening bolt 32 is inserted into the guide sleeves 31 and abuts against the outer wall of the guide rods 30. The guide sleeves 31 are provided with threaded holes for threaded connection of the hand-tightening bolts 32.

[0035] The guide rod 30 can slide inside the guide sleeve 31 and be fixed with the hand-tightening bolt 32. The distance between the inner connecting groove 25 and the receiving box 2 is controlled by the scale line, thereby controlling the distance between the receiving box 2 and the cooling conveying mechanism 1, so that the distance between the receiving box 2 and the cooling conveying mechanism 1 is the length of a packaging box semi-finished product.

[0036] The working principle of this utility model is as follows:

[0037] In use, the guide rod 30 slides within the guide sleeve 31, thereby controlling the distance between the inner connecting groove 25 and the receiving box 2 via the scale lines, and thus controlling the distance between the receiving box 2 and the cooling conveying mechanism 1. At this time, it is fixed by hand-tightening the bolt 32. The receiving box 2 is moved by the cooperation of the wheel 22 and the push handle 23, and the inner connecting groove 25 and the outer connecting groove 24 are aligned. At this time, the ramp 26 lifts the locking rod 29 along the sliding groove 28, further making the locking groove 27 and locking rod 29 correspond. At this time, the locking rod 29 falls into the locking groove 27 to form a limiting effect. At this time, the cooling conveying mechanism 1 transports the plastic packaging box to the space between the cutting blade 5 and the cutting groove 6. The electric push rod 7 drives the blade holder 4 to rise and fall, thereby cutting the plastic packaging box through the cooperation of the cutting blade 5 and the cutting groove 6. At the same time, the blade holder 4 drives the toothed plate 8 to move up and down. When the toothed plate 8 descends, it drives the spur gear 9 to rotate forward. At this time, under the action of the adjustable ratchet structure 11, the spur gear 9 drives the drive shaft 10 to rotate. At the same time, when the toothed plate 8 rises, the spur gear 9 rotates in the opposite direction without load and does not drive the drive shaft 10 to rotate. Thus, the first bevel gear 12 and the second bevel gear 13 drive the threaded rod 14 to rotate, thereby driving the placement plate 17 to descend through the threaded assembly 16. Thus, each cut plastic packaging box is gradually supported by the placement plate 17 and the plastic packaging box on it, and there will be no situation where it falls directly and causes an uneven situation. By controlling the ratchet 19 that engages with the ratchet 18 through the toggle block 20, the rotational direction of the ratchet 18 can be controlled. This allows the spur gear 9 to be driven in the opposite direction through the toothed plate 8, thereby driving the drive shaft 10 to rotate and controlling the placement tray 17 to rise, making it easier to remove the plastic packaging box located in the receiving box 2.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
