[0075] The present invention will be further described with reference to the following examples. Example 1

[0076] Referring to the attached drawings, the multi-specification material receiving and packing conveying device of this embodiment is provided with a diaphragm ring 1-3, a material receiving translation and rotation driving unit 3, a lifting driving device 4, a carton placement unit 1 and a diaphragm ring removal unit 2. The upper frame of the diaphragm ring 1-3 is provided with a magnetic attraction portion 1-31 that can be attracted by a magnetic material. The material of the ring 1-3 of the embodiment is iron. Initially, the film bag is put into the carton 5, and the carton 5 is placed in the carton placement unit 1. The lifting driving device 4 drives the carton placement unit 1 to drive the carton 5 and the diaphragm ring 1-3 to rise and align with the diaphragm ring removal unit 2 for detection, and the removal electromagnet 2-1 is adjusted to be precisely aligned with the magnetic attraction portion 1-31 of the diaphragm ring 1-3. After the alignment check is completed, the lifting drive device 4 drives the carton 5 and the diaphragm ring 1-3 to move downward and horizontally to the bottom of the box mouth limiting mechanism 3-1 of the material receiving translation and rotation drive unit 3. The lifting drive device 4 makes the carton 5 and the diaphragm ring 1-3 rise, and the carton 5 is clamped in the box mouth limiting mechanism 3-1. The material receiving translation and rotation drive unit 3 makes the carton 5 flip the opening toward the layered material receiving and packing device 6 (the layered material receiving and packing device 6 in this embodiment is the prior art recently developed and disclosed by the applicant of the present invention) for material receiving. The prior art has a very difficult problem to solve in bagging and boxing, that is, after the film bag is put into the carton, if the machine equipment is used to automatically load the product, the film bag is easily deviated, shifted, dropped or slipped into the bottom of the box. Therefore, the prior art often faces a dilemma: either automatic boxing without putting a large film bag on the product, which results in that the material can only be taken out of the carton in a scattered manner, and it is easy to contaminate and dirty the product, which does not meet the hygiene requirements; or the film bag is put on first and then the products are put in one by one manually, but the work efficiency is low and the products are not neatly arranged (affected by various unstable factors of the workers). The present invention adopts diaphragm rings 1-3 to fix the film bag, which can effectively prevent the film bag from wrinkling, shifting and sliding. At the same time, it cooperates with other equipment to realize the functions of automatic boxing and removal of the diaphragm rings 1-3 after bagging, ensuring product hygiene, neat product boxing and high work efficiency.

[0077] In this embodiment, the carton placement unit is provided with a carton limiting frame 1-1 capable of carrying carton, and the carton limiting frame 1-1 is provided with a fixed placement seat, a width telescopic limiting structure, an L-shaped length adjustment plate 1-4, a rotating limiting plate 1-5, a width adjustment driving bracket 1-2 and a width adjustment driving device, and the width adjustment driving device is installed on the width adjustment driving bracket 1-2 and drives the width telescopic limiting structure to move. The fixed placement seat includes a placement bottom plate 1-6, a width side plate 1-7 and a length side plate 1-8, and the placement bottom plate 1-6, the width side plate 1-7 and the length side plate 1-8 are all provided with a gap 1-9. The width telescopic limiting structure includes a first side plate 1-10, a second side plate 1-11 and a bottom plate 1-12, the first side plate 1-10, the second side plate 1-11 and the bottom plate 1-12 are perpendicular to each other, the first side plate 1-10 and the bottom plate 1-12 are embedded in the gap 1-9 corresponding to the fixed placement seat, and the width telescopic limiting structure can be moved forward and backward relative to the fixed placement seat to adjust the position to meet the placement requirements of cartons 5 of different widths. The width adjustment drive device of this embodiment is provided with a motor 1-21, a transmission belt 1-22 and a transmission wheel 1-23, the transmission wheel 1-23 is installed on the width adjustment drive bracket 1-2, the motor 1-21 drives the transmission wheel 1-23 to rotate, the transmission belt 1-22 is installed on the transmission wheel 1-23 and drives the width telescopic limiting structure to translate, thereby realizing automatic width adjustment.

[0078] In order to facilitate the length adjustment in the longitudinal direction, the L-shaped length adjustment plate 1-4 of this embodiment is embedded in the gap 1-9 of the fixed placement seat. In order to facilitate the removal of the carton 5 filled with products, the rotary limit plate 1-5 of this embodiment is composed of a rotary cylinder 1-13, and the rotary cylinder 1-13 is fixedly installed on the L-shaped length adjustment plate 1-4. The rotary cylinder 1-31 and the rotary limit plate 1-5 can move together with the L-shaped length adjustment plate 1-4. When the carton 5 needs to be removed, the rotary cylinder 1-31 drives the rotary limit plate 5 to rotate outward and downward to form a carton outlet.

[0079] At the same time, the carton placement unit is also provided with a clutch support side plate 1-14, a base 1-15, an angle fixing plate 1-16, and a width adjustment drive bracket 1-2 fixed to the base 1-15. The base 1-15 is vertically fixed to the clutch support side plate 1-14, and an angle fixing plate 1-16 is also provided between the base 1-15 and the clutch support side plate 1-13. The function of the angle fixing plate 1-16 is to ensure that the clutch support side plate 1-14 and the base 1-15 are perpendicular to each other to avoid errors. If the clutch support side plate 1-14 and the base 1-15 are not at a right angle, the magnetic attraction portion 1-31 of the diaphragm ring 1-3 on the carton 5 cannot be accurately aligned with the removal electromagnet 2-1, and the diaphragm ring 1-3 cannot be smoothly removed.

[0080] A guide rail 1-17 is provided on the side of the clutch supporting side panel 1-14 of the carton placing unit 1, and a slider 1-18 is slidably provided on the guide rail 1-17, and the slider 1-18 is fixedly connected with a latch connecting seat 1-19, and the latch connecting seat 1-19 is provided with a latch 1-20, and the latch connecting seat 1-19 can be fixedly connected to the aluminum profile by screws, and the latch connecting seat 1-19 can be locked at different positions of the aluminum profile according to actual needs, and in actual application, the position and quantity of the latch 1-20 and the latch connecting seat 1-19 can be adjusted according to specific circumstances, but all belong to the scope of protection required by the present invention. Correspondingly, the back plate of the rotating seat 3-5 of the material receiving translation and rotation driving unit 3 is fixed with a pin hole seat 3-2, and the pin hole seat 3-2 is provided with a pin hole. The pin 1-20 can be assembled and plugged with the pin hole of the pin hole seat 3-2. When the lifting drive device 4 drives the carton placement unit 1 to rise toward the box mouth limit mechanism 3-1, the pin 1-20 can be inserted into the pin hole seat 3-2 corresponding to the back plate of the rotating seat 3-5 to play a role in reinforcing the connection. In order to further strengthen the firmness of the connection, the back plate of the rotating seat 3-5 of this embodiment can also be provided with an electromagnet 3-15 for adsorbing the clutch support side plate 1-14 to adsorb the diaphragm ring 1-3 and the carton 5. The diaphragm ring 1-3 is provided with a part that can be adsorbed by the electromagnet, and can also be made entirely of iron, or the main body can be made of stainless steel and the part that needs to be adsorbed is made of iron. The lower part of the rotating seat 3-5 of the material receiving translation and rotation driving unit 3 is fixed with a rotating shaft 3-8, which is rotatably mounted on the bearing seat 3-9, and the bearing seat 3-9 is fixed to the translation and rotation connecting seat 3-10. The upper part of the rotating seat 3-5 is hinged with one end of the rotating connecting rod 3-11, and the other end of the rotating connecting rod 3-11 is pushed and pulled by the cylinder 3-12.

After rotation, it docks with the discharge port of the layer-by-layer material conveying device. The gate 3-3 gradually rises under the action of the gate driving device 3-4 to prevent the products transported into the carton 5 by the layer-by-layer material conveying device from falling out.

[0081] In this embodiment, the lifting drive device 4 is provided with a screw lift 4-1, a clutch lifting seat 4-2 and a lifting base plate 4-3.
