Description

Technical Field

[0001] The utility model relates to the technical field of feeding of a thin knife machine, in particular to a feeding mechanism for a thin knife machine. Background Art

[0002] A thin knife machine is a mechanical device used for carton processing, and is mainly used for the creasing process of cardboard.

[0003] The specific use of the thin knife machine is that a feeding mechanism is required to horizontally transport the cardboard, and then during the transportation process, a thin knife with a creasing cylinder will longitudinally crease the cardboard below to facilitate the subsequent bending by workers and prepare for subsequent mutual adhesion to form a finished carton.

[0004] Currently, for the existing feeding mechanism of a thin knife machine, when longitudinally creasing the cardboard below with the thin knife, since the conveyor belt itself is relatively soft, the downward moving thin knife will cause the conveyor belt itself to deform downward, which will in turn affect the longitudinal creasing effect on the cardboard.

[0005] In addition, for the existing feeding mechanism of a thin knife machine, when transporting the cardboard, if not paying attention, if it is collided by an external object, the cardboard will directly slide off the conveyor belt, which overall reduces the anti-slip conveying stability of the conveyor belt on the feeding mechanism of the thin knife machine for the cardboard. Summary of the Utility Model

[0006] The purpose of the utility model is to solve the above-mentioned drawbacks existing in the prior art, and to propose a feeding mechanism for a thin knife machine.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] Design a feeding mechanism for a thin knife machine, including a feeding mechanism. A fixed surface is provided below the feeding mechanism. A thin knife creasing device is provided on the fixed surface. A conveyor belt is provided on the feeding mechanism. The thin knife creasing device consists of a creasing cylinder, a lifting plate, a knife holder, and a thin knife. The lifting plate is arranged on the creasing cylinder. The knife holder is arranged on the lifting plate. The thin knife is arranged on the knife holder;

[0009] Columns are provided on the fixed surface. A connecting block is provided on the columns. A base plate is provided on the connecting block. Support balls and a support top plate are provided on the base plate. A smooth coating is provided on the support top plate;

[0010] Side anti-slip pads are provided on the conveyor belt. Top anti-slip pads are provided on the side anti-slip pads.

[0011] Further, the struts and the connecting blocks are grouped into a total of four groups which are symmetrically arranged. The two ends of each strut are fixedly arranged with the fixed surface and the bottom of the connecting block respectively, and the inner ends of the connecting blocks are fixedly arranged at the corners of the base plate.

[0012] Further, neither the struts nor the connecting blocks are in contact with the conveyor belt, and there is a gap between the upper and lower end faces of the base plate and the conveyor belt.

[0013] Further, the overall shape of the supporting top plate is rectangular, and the top view cross-sectional dimension of the supporting top plate is not less than that of the thin blade.

[0014] Further, there are four symmetrically arranged supporting balls which are rolling and clamped in the base plate, and the outer wall surface of the supporting balls is in rolling contact with the conveyor belt.

[0015] Further, the side anti-slip pads and the top anti-slip pads are grouped into a total of two groups which are symmetrically arranged. The side anti-slip pads are arranged on the side wall surface of the conveyor belt, and the side cross-section of the top anti-slip pads is of a bent structure.

[0016] Further, the smooth coating is evenly coated along the top surface of the supporting top plate. The smooth coating is a ceramic coating with a thickness of 50 to 60 microns.

[0017] The feeding mechanism for a thin blade machine proposed by the present utility model has the beneficial effects as follows:

[0018] 1. By arranging struts with connecting blocks on the fixed surface, and arranging a base plate with supporting balls and a supporting top plate on the connecting blocks, and then arranging a smooth coating structure on the supporting top plate, when longitudinally pressing the cardboard on the lower conveyor belt with a thin blade, the bottom of the longitudinally pressed part of the conveyor belt can be stably supported, avoiding the situation of downward deformation due to the relatively soft conveyor belt itself, and thus ensuring the longitudinal pressing effect on the cardboard.

[0019] 2. By arranging side anti-slip pads on the side wall surface of the conveyor belt and arranging top anti-slip pads with a bent structure on the side anti-slip pads, an effective and stable anti-slip effect on the side and top of the cardboard during the feeding process is achieved, avoiding the situation that the cardboard directly slips off the conveyor belt due to being accidentally collided by external objects during transportation, and overall improving the anti-slip and transportation stability of the conveyor belt on the feeding mechanism of the thin blade machine for the cardboard.

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0027] Referring to Figures 1-5 , a feeding mechanism for a thin blade machine includes a feeding mechanism 1. A fixing surface 10 is provided below the feeding mechanism 1. A thin blade wire pressing device 2 is provided on the fixing surface 10. A conveyor belt 11 is provided on the feeding mechanism 1. The thin blade wire pressing device 2 is composed of a wire pressing cylinder 21, a lifting plate 22, a tool holder 23, and a thin blade 24. The lifting plate 22 is provided on the wire pressing cylinder 21. The tool holder 23 is provided on the lifting plate 22. The thin blade 24 is provided on the tool holder 23;

[0028] A support column 4 is provided on the fixing surface 10. A connecting block 41 is provided on the support column 4. A base plate 5 is provided on the connecting block 41. A supporting ball 51 and a supporting top plate 6 are provided on the base plate 5. A smooth coating 7 is provided on the supporting top plate 6;

[0029] A side anti-detachment pad 3 is provided on the conveyor belt 11. A top anti-detachment pad 31 is provided on the side anti-detachment pad 3. The feeding mechanism 1 and the thin blade wire pressing device 2 are both prior arts. Some existing structures are not drawn and labeled, so there is no need to elaborate.

[0030] The support columns 4 and the connecting blocks 41 are grouped into a set, and there are a total of four sets arranged symmetrically. The two ends of the support columns 4 are respectively fixedly arranged with the fixed surface 10 and the bottom of the connecting blocks 41. The inner ends of the connecting blocks 41 are fixedly arranged at the corners of the base plate 5, improving the stability of the overall support structure for the supporting top plate 6.

[0031] Neither the support columns 4 nor the connecting blocks 41 are in contact with the conveyor belt 11. There is a spacing between the upper and lower end faces of the base plate 5 and the conveyor belt 11, avoiding frictional phenomena caused by contact with the conveyor belt 11.

[0032] The overall supporting top plate 6 is in a rectangular structure. The top view cross-sectional dimension of the supporting top plate 6 is not less than the top view cross-sectional dimension of the thin blade 24, ensuring the overall effective bottom stable support for the longitudinally pressed line part.

[0033] There are four symmetrically arranged supporting balls 51 which are rolling and clamped in the base plate 5. The outer wall surface of the supporting balls 51 is in rolling contact with the conveyor belt 11. The supporting balls 51 are made of high-speed steel, and two-thirds of their spherical bodies are embedded in the base plate 5. On the premise of preventing them from slipping out of the base plate 5, the rolling contact supporting effect between the supporting balls 51 and the conveyor belt 11 is ensured.

[0034] The side anti-slip pads 3 and the top anti-slip pads 31 are grouped into a set, and there are a total of two sets arranged symmetrically. The side anti-slip pads 3 are arranged on the side wall surface of the conveyor belt 11. The side cross-section of the top anti-slip pads 31 is in a bent structure. Both the side anti-slip pads 3 and the top anti-slip pads 31 are made of vulcanized rubber material, realizing the effective and stable anti-slip effect on the side and top of the cardboard during the feeding process, avoiding slipping.

[0035] The smooth coating 7 is evenly coated along the top surface of the supporting top plate 6. The smooth coating 7 is a ceramic coating with a thickness of 50 to 60 microns. The ceramic coating has excellent smoothness, and the surface is flat and smooth, ensuring the smooth movement between it and the conveyor belt 11.

[0036] Working method: Start the preset motor on the feeding mechanism 1, and horizontally feed the placed cardboard from left to right through the preset rollers and the conveyor belt 11. When the cardboard is conveyed below the thin blade 24, the preset controller will start the pressing line cylinder 21, and drive the thin blade 24 to move downward quickly through the lifting plate 22 and the tool holder 23 to longitudinally press the cardboard, which is the prior art;

[0037] At this time, the supporting top plate 6 with the smooth coating 7 arranged at the bottom can stably support the longitudinally pressed line part of the conveyor belt 11 from the bottom, avoiding the situation of downward deformation caused by the relatively soft conveyor belt 11 itself, and thus ensuring the longitudinal pressing line effect on the cardboard.

[0038] In addition, by providing a side anti-slip pad 3 on the side wall surface of the conveyor belt 11 and a top anti-slip pad 31 with a bending structure on the side anti-slip pad 3, an effective and stable anti-slip effect on the side and top of the cardboard during the feeding process is achieved, avoiding the situation where the cardboard directly slips off the conveyor belt 11 due to being accidentally collided by foreign objects during transportation, and overall improving the anti-slip conveying stability of the conveyor belt 11 on the feeding mechanism for the thin-blade machine with respect to the cardboard.

[0039] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
