Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of packaging cartons, and particularly relates to a cutting mechanism. BACKGROUND

[0002] With the rapid development of intelligent warehousing logistics in recent years, the trend of warehouse intelligence and few people is more and more obvious. Before the current conventional warehouse, the package (the raw material is taken out from the incoming paper box and transferred to the turnover box) needs to be manually cut with an art knife to open the horizontal (middle seam) and two vertical (edge seam) tapes on the top surface of the paper box (hereinafter referred to as cutting box) before the package action can be performed. And because of the variety of materials, the size of the paper box is different, and it needs to be compatible to the greatest extent. Because the paper box is quite different, the same type of paper box also has a large difference due to the collision and extrusion in the transportation process, and the overall rigidity of the upper and lower surfaces of the paper box is inconsistent, the rigidity near the edge position is stronger, and the rigidity of the middle part is poorer, which leads to poor consistency of the cutting amount when opening the horizontal (middle seam) tape, and it is easy to appear that the cutting depth is too large to scratch the material in the box or the cutting depth is too shallow to open the tape, etc. Adverse, reducing the reliability of the tape cutting.

[0034] With the rapid development of intelligent warehousing logistics related fields in recent years, the trend of warehouse intelligence and few people is more and more obvious. Taking the warehouse of 3C electronic enterprise as an example, the production rhythm is fast, and the personnel demand is large. In the face of the current high personnel turnover and difficult recruitment situation, automation and intelligence are the best solution.

[0035] The current conventional warehouse needs to manually use a knife to cut a horizontal (middle seam) and two vertical (edge seam) tapes on the top surface of the carton (hereinafter referred to as cutting box) before the carton (taking out the raw materials from the incoming carton and transferring them to the turnover box) action can be performed. And because of the variety of materials, the size of the carton is different, and needs to be compatible to the greatest extent. And the carton as garbage also needs to cut a horizontal and two vertical tapes on the bottom surface in the subsequent processing, and the carton is collected flat. The cutting action does not produce value, wastes time, and the knife has a certain safety risk in use.

[0036] Because of the large difference of the carton, the same type of carton also has a large difference due to the collision and extrusion in the transportation process, and the overall rigidity of the upper and lower surfaces of the carton is inconsistent, the rigidity near the edge position is strong, and the rigidity of the middle part is poor, which leads to the problem that the cutting amount consistency of the horizontal (middle seam) tape cutting is poor, and the edge cutting is deep and the middle cutting is shallow. At the same time, because the blade is sharp, it is easy to scratch the operator when changing the blade or cleaning the blade.

[0037] Figure 1 The combination structure schematic diagram of the box body 200 and the two cutting mechanisms 100 according to the embodiment of the application is schematically shown. Figure 2 For Figure 1 The structure schematic diagram of the middle cutting mechanism 100. As Figure 1 And 2As shown, the present application provides a cutting mechanism 100. The cutting mechanism 100 in the present application comprises a fixed seat 10, a cutter assembly and a guide piece. The cutter assembly comprises a sliding piece and a cutter body 21. The sliding piece is arranged on the fixed seat 10 and is elastically connected with the fixed seat 10. The cutter body 21 is arranged on the sliding piece. The sliding piece is used to drive the cutter body 21 to move towards or away from the fixed seat 10. The guide piece is connected with the sliding piece and is located on the side of the sliding piece away from the fixed seat 10. The side of the guide piece away from the fixed seat 10 is used to abut against a box body 200. The guide piece is provided with an opening 35. The side of the cutter body 21 away from the fixed seat 10 has a cutting end. The cutting end penetrates the opening 35 and extends to the side of the guide piece away from the fixed seat 10. The cutting end is used to cut the adhesive tape of the box body 200.

[0038] According to the technical scheme of the present application, the fixed seat 10 can fix and support the cutter assembly and the guide piece. The cutter assembly is aligned with the position of the adhesive tape of the box body 200. When the cutting operation of the adhesive tape of the box body 200 is performed, the box body 200 will move to the side of the guide piece away from the fixed seat 10 and abut against the guide piece. Since the guide piece is connected with the sliding piece and the sliding piece is elastically connected with the fixed seat 10, the elastic force can always keep the guide piece abutting against the box body 200. The cutting end exposed from the opening 35 of the guide piece has a consistent cutting amount into the box body 200. The situation that the box body 200 is squeezed and deformed to cause the cutter body 21 to cut too deeply and scratch the materials in the box, or the situation that the cutter body 21 cuts too shallowly and cannot cut the adhesive tape is effectively reduced. The reliability of the cutting mechanism 100 for cutting the adhesive tape of the box body 200 is improved.

The sliding connection can ensure the moving direction of the fixed part 221 of the sliding piece, thereby ensuring the accuracy of the moving direction of the sliding piece. In addition, the other end of the connecting part 222 is connected with the fixed seat 10 through the elastic piece 25, thereby realizing the elastic connection between the sliding piece and the fixed seat 10. When the box body 200 contacts the guide piece, the other end of the connecting part 222 can change with the height change of the side of the box body 200 towards the guide piece, thereby realizing that the side of the box body 200 towards the guide piece always abuts against the guide piece. The cutting end exposed from the opening 35 of the guide piece has a consistent cutting amount into the box body 200. The reliability of the cutting operation of the adhesive tape is improved.

In the present embodiment, the detachable connection between the guard 26 and the cutter body 21 facilitates the dismounting or mounting of the guard 26 from or on the cutter body 21, and the detachable connection between the cutter body 21 and the sliding member facilitates the dismounting or mounting of the cutter body 21 from or on the sliding member. The detachable connection facilitates the dismounting and replacement of parts without damaging the entire structure or system, and when the parts are repaired or replaced, the quick dismounting and re-mounting can greatly reduce the downtime of the equipment and improve the production efficiency.

[0047] Specifically, as shown in Figure 3 and 3 In the present embodiment, the combination of the bolt 28 and the nut is used to fix the guard 26, the cutter body 21 and the sliding member. The bolt 28 is sequentially arranged through the guard 26, the cutter body 21 and the sliding member and cooperates with the nut to realize the fixing operation. In the direction of the cutter body 21 towards the fixing base 10, the guard 26 is provided with the first fixing hole 262, the sliding member is provided with the second fixing hole, and the cutter body 21 is provided with the third fixing hole.

In the embodiment, the connecting portion 31 is used to connect the sliding piece and the guide piece, and the abutting portion 32 is used to abut against the box body 200. When the box body 200 moves towards one direction of the cutting mechanism 100, the box body 200 will first contact the first guide portion 33, since one end of the first guide portion 33 away from the abutting portion 32 is bent and arranged towards the fixed base 10, the first guide portion 33 can be arranged obliquely, after the box body 200 contacts the first guide portion 33, the box body 200 will move along the extension direction of the first guide portion 33, and finally reach the position of the abutting portion 32, and the adhesive tape on the box body 200 is cut by the cutter body 21.

[0049] When the box body 200 moves towards the other direction of the cutting mechanism 100, the box body 200 will first contact the second guide portion 34, since one end of the second guide portion 34 away from the abutting portion 32 is bent and arranged towards the fixed base 10, the second guide portion 34 can be arranged obliquely, after the box body 200 contacts the second guide portion 34, the box body 200 will move along the extension direction of the second guide portion 34, and finally reach the position of the abutting portion 32, and the adhesive tape on the box body 200 is cut by the cutter body 21.

[0050] Specifically, in the embodiment, the guide piece can also prevent the cutter body 21 from excessively penetrating into the carton.

[0051] In some embodiments of the present application, as shown in Figure 1 and 4 As shown, the cutting mechanism 100 further comprises a sliding rail 40 and a sliding block 50, the sliding rail 40 is arranged on the fixed base 10, the sliding block 50 is in sliding connection with the sliding rail 40, and the sliding piece is arranged on the sliding block 50 and can move towards or away from the fixed base 10 along with the sliding block 50.

[0052] In some embodiments of the present application, as shown in ​As shown, the cutting mechanism 100 is provided with two, two cutting mechanisms 100 are arranged at intervals, and a containing space is formed between the two cutting mechanisms 100, and the cutting end of the cutter body 21 of each cutting mechanism 100 is arranged towards the containing space. In this embodiment, since the opposite two side surfaces of the box body 200 need to be bonded with adhesive tape, the two cutting mechanisms 100 can be arranged to cut the adhesive tape from the opposite two side surfaces of the box body 200 respectively, thereby improving the integrity of the cutting of the adhesive tape of the box body 200.

[0053] Further, the working principle of the cutting mechanism 100 in the present application is as follows: when the middle seam positions of the opposite two side surfaces of the carton are respectively aligned with the cutter bodies 21 of the two cutting mechanisms 100, the carton is pushed forward, and the carton enters the containing space along the guide surface of the first guide away from one side of the fixed seat 10 or the guide surface of the second guide away from one side of the fixed seat 10 during the running process, and the carton will push the guide and the cutter body 21 away from the direction of the fixed seat 10, and under the action of the elastic member 25, the cutter body 21 and the guide will always move along the upper (or lower) end surface of the carton, achieving the effect of automatic adjustment according to the shape and position of the carton, adjusting the relative position of the guide and the cutter body 21 (i.e. adjusting the cooperation position of the positioning pin and the first positioning hole 261 and the second positioning hole 2211), thereby adjusting the protruding amount of the cutting end of the cutter body 21, and after the adjustment is completed, the relative protruding length of the cutting end of the cutter body 21 and the guide is fixed, and the guide can prevent the cutter body 21 from excessively penetrating into the carton, so that the cutter body 21 can always move along the middle seam of the carton at a fixed angle and protruding amount, achieving the purpose of uniformly cutting the adhesive tape of the middle seam of the carton.

[0054] When the cutter body 21 needs to be replaced or cleaned, a gap is loosened between the protection member 26 and the cutter body 21, the positioning pin is pulled out, the cutter body 21 is moved forward by one grid (i.e. the through hole of the cutter body 21 is cooperated with the next first positioning hole 261 and the second positioning hole 2211), and the worn blade is removed or a new blade is directly replaced, and after the replacement is completed, the positioning pin is inserted back and the cutter body 21, the protection member 26 and the sliding member are locked. Since the protection member 26 does not need to be removed during the whole cutter replacement process, the protection member 26 can always limit the activity range of the cutter body 21 during the whole cutter replacement process, thereby protecting the operator.

[0055] Specifically, in this embodiment, the cutter body 21 can be a wallpaper blade structure, and the blade can be reused by being broken into segments.

[0056] Further, the cutting mechanism 100 of the present application can be compatible with the cutting and slotting of adhesive tape of various sizes of cartons, and can be perfectly compatible with cartons of different sizes and different incoming states. It can also ensure the consistency of the state of the cut and slotted adhesive tape, the uniformity of the cutting amount, and effectively avoid the cutting depth being too large to scratch the contents of the carton or the cutting being too shallow to cut the adhesive tape. In addition, it can also effectively reduce the safety risk of the operator when replacing and cleaning the blade.

[0057] The above merely describes the preferred embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present application, which shall be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
