Description

Technical Field

[0001] The utility model relates to the technical field of carton processing, and in particular to a creasing wheel used for processing creasing lines on paperboard during carton processing. The utility model also relates to a carton machine provided with the explosion-proof creasing wheel. Background Art

[0002] In the process of processing cardboard into flat-shaped semi-finished carton products, the carton machine can process horizontal grooves, horizontal indentation lines, vertical indentation lines, and handle holes on the cardboard. Some carton machines can also cut out tongues for bonding and apply glue on the tongues.

[0003] When the cardboard material is poor or the weather is dry, the creasing wheel of the carton machine is prone to cracking during creasing (referring to the creasing process in the corrugated paper processing technology, which causes the cardboard to crack), especially during the corrugated processing, which leads to unqualified quality of the produced cartons.

[0004] Traditional equipment mostly uses the method of upper and lower wheels or upper pressing wheel with roller to achieve wire pressing. The wire pressing wheel combination mainly includes: upper pressing wheel 1 is a three-wire wheel, lower pressing wheel 2 is a double-wire wheel (see Figure 1 , Figure 2 ); the upper pressing wheel is a single-line wheel, the lower pressing wheel is an arc wheel and other combinations. Among them, the upper pressing wheel 1 is a three-line wheel, and the lower pressing wheel 2 is a double-line wheel. The combination can better ensure the pressing effect of the cardboard 3 and reduce the phenomenon of cracking.

[0005] Although the combination of the upper pressing wheel 1 being a three-line wheel and the lower pressing wheel 2 being a double-line wheel can better ensure the pressing effect and reduce the phenomenon of cracking, because there are pressing lines on both the upper and lower sides, there will be bulges on the back of the cardboard 3 after pressing, which will affect the subsequent processes of carton processing such as digital printing, and the upper and lower wheels need to move and position synchronously in the fully automatic equipment, which is complex in structure and high in cost.

[0036] Please refer to Figures 3 to 5 , Figure 3 It is a structural schematic diagram of a first type of explosion-proof wire crimping wheel provided by an embodiment of the utility model; Figure 4 for Figure 3 AA view; Figure 5 for Figure 3 Axonometric view of the explosion-proof wire crimping wheel shown.

[0037] As shown in the figure, in a specific embodiment, the explosion-proof wire crimping wheel provided by the utility model is mainly composed of two parts: a core shaft 10 and a rubber-coated wheel 20, wherein the core shaft 10 is made of metal, the rubber-coated wheel 20 is made of rubber, and the rubber-coated wheel 20 is located on the outside of the core shaft 10.

[0038] Specifically, the core shaft 10 is provided with an axial hole 11 for connecting the rotating shaft, and the rubber-coated wheel 20 is coated on the outer periphery of the core shaft 10. The rubber-coated wheel 20 is integrally formed and has a spoke portion 21 and a wheel surface portion 22. The spoke portion 21 is provided with a hollow portion 23 that passes through along the axial direction. Each hollow portion 23 is generally in the form of a right-angled triangle, wherein the first acute angle thereof is greater than the second acute angle and the second acute angle points to the center of the circle, the long side of the right angle thereof is located in the radial direction, and the direction of the short side of the right angle from the first acute angle to the right angle is the direction of rotation. Multiple hollow portions 23 are evenly distributed along the circumferential direction, and spokes 24 are formed between adjacent hollow portions 23. The entire hollow portion 23 forms a pressure buffer area between the core shaft 21 and the wheel surface portion 22, and this area can be elastically deformed when the cardboard is pressed.

[0039] The outer surface of the wheel portion 22 is in a shape in which the middle portion 221 is higher than the two side portions 222. In this embodiment, the outer surface of the wheel portion 22 is in an inverted "V" shape in cross section, and the middle portion 221 can be flat or curved, which is used to press the cardboard.

[0040] Please refer to Figure 6 , Figure 6 A schematic structural diagram of a second explosion-proof wire crimping wheel provided in an embodiment of the utility model.

[0041] As shown in the figure, compared with the first embodiment, the difference of this embodiment is:

[0042] The two ends of the hollow portion 23 of the rubber-coated wheel 20 are semicircular, the circular diameter of the first end is larger than the circular diameter of the second end, the first end is far away from the center of the circle, the width of the hollow portion 23 gradually narrows from the first end to the second end, and the center line from the first end to the second end is located in the radial direction.

[0043] In this embodiment, the same parts as those in the first embodiment are given the same figure marks, and the same text descriptions are omitted.

[0044] Please refer to Figure 7 , Figure 7 A schematic structural diagram of a third explosion-proof wire crimping wheel provided in an embodiment of the utility model.

[0045] As shown in the figure, compared with the first embodiment, the difference of this embodiment is:

[0046] The hollow portion 23 of the rubber-coated wheel 20 includes a first circular hole portion and a second circular hole portion. The diameter of the first circular hole portion is greater than the diameter of the second circular hole portion. The line connecting the centers of the first circular hole portion and the second circular hole portion is located in the radial direction, and the first circular hole portion is far away from the center.

[0047] In this embodiment, the same parts as those in the first embodiment are given the same figure marks, and the same text descriptions are omitted.

[0048] Please refer to Figure 8 , Figure 8 A schematic structural diagram of a fourth explosion-proof wire crimping wheel provided in an embodiment of the utility model.

[0049] As shown in the figure, compared with the first embodiment, the difference of this embodiment is:

[0050] The hollow portion 23 of the rubber-coated wheel 20 is in an oblong shape, and a center line from the first end to the second end thereof is located in a radial direction, and spokes 24 are formed between adjacent hollow portions 23 .

[0051] In this embodiment, the same parts as those in the first embodiment are given the same figure marks, and the same text descriptions are omitted.

[0052] The above embodiments are only preferred solutions of the present invention and are not limited thereto. On this basis, targeted adjustments can be made according to actual needs to obtain different implementation methods. For example, the rotating shaft and the core shaft 10 are an integrated structure, etc. Since there are many possible implementation methods, they will not be described one by one here.

[0053] In order to ensure the creasing effect, a certain amount of pressure must be applied to the cardboard. If the pressure is too small, the indentation will be shallow and the molding effect will be poor. If the pressure is too large, the cardboard will burst.

[0054] The utility model can form a line pressing effect on the cardboard by designing the outer ring to be high in the middle and low on both sides, and can form a line pressing effect on the cardboard by designing a hollow shape on the spoke part 21, so that it can be deformed under pressure and reduce the pressure of the line pressing wheel on the cardboard. In this way, the rubber-coated material, the hollow shape, and the high in the middle and low on both sides work together to achieve the effect of explosion-proof line while ensuring the line pressing effect.

[0055] like Fig.11 As shown, the indentation line A is the indentation effect of the explosion-proof wire creasing wheel of the utility model, and the indentation lines B, C, and D are the indentation effects of three different traditional creasing wheels. By comparison, it can be found that the indentation line A processed by the explosion-proof wire creasing wheel of the utility model is more uniform and consistent, and there is no excess rolling mark parallel to the indentation, and there is no cracking on the indentation line.

[0056] Moreover, the explosion-proof wire pressing wheel is used as the upper pressing wheel. When positioning the pressing wheel, it is only necessary to move the upper pressing wheel. It has a simple structure. And because of the single-sided pressing, there will be no indentation on the back, which can ensure the processing quality of the cardboard and solve the problem of pressing of corrugated cardboard, honeycomb cardboard and other cardboards.

[0057] Please refer to Fig. 9 , Fig.10 , Fig. 9 A schematic structural diagram of a longitudinal crimping unit of a carton machine provided by an embodiment of the utility model; Fig.10 for Fig. 9 A side view of the longitudinal crimping unit is shown.
