However, because the indentation wheels must be mounted on a connecting rod, the minimum distance between the two indentation wheels during adjustment is limited by the size of the mounting frame and the indentation wheels themselves. This makes it impossible to create two indentations with a small distance between them on the cardboard. Utility Model Content

[0041] In order to enable those skilled in the art to better understand the present invention and thus more clearly define the scope of protection claimed by the present invention, the present invention is described in detail below with respect to certain specific embodiments of the present invention. It should be noted that the following are only certain specific implementation methods of the present invention, which are only part of the embodiments of the present invention. The specific and direct description of the relevant structures is only for the convenience of understanding the present invention, and the specific features do not naturally and directly limit the scope of implementation of the present invention. The conventional selections and replacements made by those skilled in the art under the guidance of the present invention should be deemed to be within the scope of protection claimed by the present invention.

[0042] Example 1:

[0043] like Figure 1-Figure 7 As shown, the utility model discloses a rubber roller matching indentation structure and a carton forming device, comprising a mounting frame 1, multiple groups of first indentation components 2, multiple groups of second indentation components 3, a first rubber roller 4 and a second rubber roller 5.

[0044] Among them, the first indentation component 2 and the second indentation component 3 are both slidably arranged on the mounting frame 1 along the left and right directions, and the first indentation component 2 and the second indentation component 3 are staggered in the front and back directions so that the movement trajectories of the first indentation component 2 and the second indentation component 3 do not interfere with each other. Specifically, the first indentation component 2 is in front and the second indentation component 3 is in the back, so that the cardboard is transported from front to back and first passes through the first indentation component 2 and then passes through the second indentation component 3.

[0045] Among them, the first rubber roller 4 is located directly below the first indentation component 2, the second rubber roller 5 is located directly below the second indentation component 3, and the axial directions of the first rubber roller 4 and the second rubber roller 5 are both in the left and right directions, and are rotatably mounted on the mounting frame 1 at both ends by bearings, wherein the first indentation component 2 slides and cooperates with different positions of the first rubber roller 4, and the first rubber roller 4 is used to cooperate with the first indentation component 2 to produce an indentation on the cardboard transmitted between the first rubber roller 4 and the first indentation component 2. Similarly, the second indentation component 3 slides and cooperates with different positions of the second rubber roller 5, and the second rubber roller 5 is used to cooperate with the second indentation component 3 to produce an indentation on the cardboard transmitted between the second rubber roller 5 and the second indentation component 3.

[0046] Therefore, 1. The first indentation component 2 is slid and adjusted to the corresponding position on the mounting frame 1, so that when the carton is transported, the carton is clamped with the first rubber roller 4 to realize the indentation processing. Similarly, the second indentation component 3 is slid and adjusted to the corresponding position on the mounting frame 1, so that when the carton is transported, the carton is clamped with the second rubber roller 5 to realize the indentation processing. Among them, since the first indentation component 2 and the second indentation component 3 are misaligned in the front and back directions, any position adjustment between the two will not interfere with each other, so as to realize the two adjacent indentations formed on the carton. The minimum spacing between them is any spacing, and even the indentations processed by the first indentation component 2 and the second indentation component 3 are the same indentation, but have the effect of deepening the indentation. 2. The first rubber roller 4 and the second rubber roller 5 are used to cooperate with the first indentation component 2 and the second indentation component 3. Not only the elasticity of the rubber roller itself is utilized to make the indentation component squeeze the deformed rubber roller to achieve a more obvious indentation, but compared with the transmission of the conveyor belt, the rubber roller only contacts the cardboard at the indentation position when deformed, and will not contact the non-indentation position to cause the cardboard to bend and affect the flatness of the cardboard.

[0047] Specifically, the first indentation assembly 2 in this embodiment includes a first slide 21, a first lifting member 22, a first carrier 23 and a first indentation wheel 24. The first slide 21 is slidably arranged on the mounting frame 1, and the first indentation wheel 24 is rotatably arranged on the first carrier 23 by means of bearings or the like. The upper end of the first lifting member 22 is fixedly mounted on the lower end of the first slide 21 by means of bolts, and the output shaft of the first lifting member 22 faces downward, and is fixedly mounted on the upper end of the first carrier 23 by means of bolts, so as to realize the connection between the first slide 21 and the first carrier 23 so as to drive the first indentation wheel 24 close to or away from the first under the operation of the first lifting member 22. The second indentation assembly 3 includes a second slide 31, a second lifting member 32, a second carrier 33 and a second indentation wheel 34. The second slide 31 is slidably arranged on the mounting frame 1, and the second indentation wheel 34 is rotatably arranged on the second carrier 33 by means of bearings or the like. The upper end of the second lifting member 32 is fixedly mounted on the lower end of the second slide 31 by means of bolts, and the output shaft of the second lifting member 32 faces downward, and is fixedly mounted on the upper end of the second carrier 33 by means of bolts to realize the connection between the second slide 31 and the second carrier 33 so as to drive the second indentation wheel 34 close to or away from the second rubber roller 5 under the operation of the second lifting member 32.

[0048] Therefore, 1. When performing the sliding adjustment of the first indentation component 2 or the second indentation component 3, the first indentation wheel 24 or the second indentation wheel 34 is first raised by the first lifting member 22 or the second lifting member 32 to prevent it from contacting the first rubber roller 4 or the second rubber roller 5, so that the subsequent sliding adjustment is smoother and has a protective effect on the first rubber roller 4 or the second rubber roller 5. 2. When indentation is required, it can be controlled according to the specific requirements of the indentation. If the indentation is a continuous indentation formed on the cardboard from beginning to end, the indentation wheel can be lowered directly after adjustment to perform indentation. If the indentation is formed on a certain section of the cardboard, the on-off control is used to realize that when the position where the cardboard needs to be indented is transmitted to the bottom of the corresponding indentation wheel, the indentation wheel is driven downward to press on the cardboard to form an indentation, and the indentation wheel is driven to be lifted after the indentation is completed at the position where the indentation is required.

[0049] Specifically, the mounting frame 1 is provided with a first guide rail 11 extending left and right on the front side and a second guide rail 12 extending left and right on the rear side; the first indentation assembly 2 is provided with a first slider 25 slidably mounted on the first guide rail 11, and the second indentation assembly 3 is provided with a second slider 35 slidably mounted on the second guide rail 12. The first indentation assembly 2 can be adjusted by the cooperation of the first guide rail 11 and the first slider 25, while the second indentation assembly 3 can be adjusted by the cooperation of the second guide rail 12 and the second slider 35.

[0050] Preferably, the first lifting member 22 is a pneumatic cylinder, and the second lifting member 32 is a pneumatic cylinder, so that the rapid drive of the pneumatic cylinder can realize rapid state conversion and better adaptability.

[0051] Preferably, the first indentation component 2 in this embodiment also includes a first pressure regulating valve connected to the first lifting member 22 for controlling the force of the first indentation wheel 24 acting on the first rubber roller 4, and the second indentation component 3 also includes a second pressure regulating valve connected to the second lifting member 32 for controlling the force of the second indentation wheel 34 acting on the second rubber roller 5, so as to achieve indentation processing of different depths and adapt to different processing requirements, different cardboard materials, thicknesses, etc.

[0052] In addition, this embodiment also includes an adjustment component for driving the first indentation component 2 and the second indentation component 3 to slide, so that the adjustment of the first indentation component 2 and the second indentation component 3 can be automatically achieved through the adjustment component, which is more accurate and convenient.

[0053] The adjustment components may include the following three types, and the three types may be combined arbitrarily.

[0054] The first type is that the adjustment component adopts the first adjustment component, the first adjustment component includes a first drive member 61, a first screw rod 62, and a first nut 63. The first screw rod 62 is rotatably installed on the mounting frame 1, and the first drive member 61 is fixed on the mounting frame 1 by means of bolts. One end of the first screw rod 62 is connected to the output shaft of the first drive member 61 by a coupling, and the first screw rod 62 is driven to rotate through the operation of the first drive member 61. The first nut 63 is fixed on the first indentation component 2 or the second indentation component 3 by means of bolts, etc., and is threadedly matched with the first screw rod 62.

[0055] Therefore, under the operation of the first driving member 61, the first screw rod 62 and the first nut 63 are threadedly matched to perform sliding driving of the first indentation component 2 or the second indentation component 3. It should be noted that if the first screw rod 62 is a single thread direction, the first indentation components 2 or the second indentation components 3 connected thereto will move synchronously in the same direction. If the first screw rod 62 is a double thread direction and the indentation components are matched on both thread sections, the indentation components on different thread sections will move synchronously in opposite directions.

[0056] The second type is that the adjustment component adopts the second adjustment component, and the second adjustment component includes a second driving member 71, a second active wheel 72, a second driven wheel 73 and a second belt 74. The second driving member 71 is fixed on the mounting frame 1 by means of bolts, and the second active wheel 72 is set on the output shaft of the second driving member 71 by means of a key connection to be driven to rotate. The second driven wheel 73 is rotatably mounted on the mounting frame 1 by means of a bearing or the like. The second belt 74 connects the second active wheel 72 and the second driven wheel 73, and the first indentation component 2 or the second indentation component 3 is connected to the second belt 74 by means of a clamp or the like.

[0057] Therefore, under the operation of the second driving member 71, the second belt 74 is driven by the second driving wheel 72 and the second driven wheel 73 to transmit and perform sliding drive of the first indentation component 2 or the second indentation component 3. It should be noted that if the indentation components are all connected to the same side of the second belt 74, the indentation components connected thereto will move synchronously in the same direction. If the indentation components are connected to different sides of the second belt 74, the indentation components connected on different sides will move synchronously in opposite directions.

[0058] The third type is that the adjustment component adopts the third adjustment component, and the third adjustment component includes a third driving member 81, a third rack 82, and a third gear 83. The third driving member 81 is set on the first indentation component 2 or the second indentation component 3 by means of bolts, that is, the third driving member 81 is set on the indentation component that needs to be adjusted by the third adjustment component. Correspondingly, the third gear 83 is set on the output shaft of the third driving member 81 to be driven to rotate, and the third rack 82 is set on the mounting frame 1 by means of bolts and engages with the third gear 83.

[0059] Therefore, under the operation of the third driving member 81, the sliding drive of the first indentation component 2 or the second indentation component 3 is performed through transmission through the engagement of the third gear 83 and the third rack 82. It should be noted that the movement of each indentation component is independent of each other and will not affect the position adjustment of other indentation components.

[0060] The first driving member 61 , the second driving member 71 , and the third driving member 81 are all precisely controlled by servo motors.

[0061] Among them, the first rubber roller 4 and the second rubber roller 5 can be actively rotated to transport the cardboard, or can be passively driven to drive the cardboard. In this embodiment, the first rubber roller 4 and the second rubber roller 5 are connected by a gear set and are actively driven by a motor.

[0062] In other embodiments, only one set of first indentation components 2 and / or one set of second indentation components 3 may be provided.

[0063] In this embodiment, the left-right direction is defined as the x direction, and the front-back direction is defined as the y direction. In other reference frames, x and y can be any non-codirectional directions.

[0064] In addition, any first creasing wheel 24 and second creasing wheel 34 in this embodiment can be used Figure 6 、 Figure 7 The single-mark indentation wheel shown can also be used Figure 8 The double-mark creasing wheel shown. It should be noted that the single-mark creasing wheel 24 is a creasing wheel with a single annular protrusion 9 arranged on its outer circumference, so that when the cardboard passes through, the protruding annular protrusion 9 presses an indentation. Correspondingly, the double-mark creasing wheel is a creasing wheel with two annular protrusions 9 arranged axially on its outer circumference, so that when the cardboard passes through, the two protruding annular protrusions 9 press two indentations simultaneously, and the distance between the two indentations is the distance between the indentation positions of the two annular protrusions 9.

[0065] Example 2:

[0066] A carton forming device includes the rubber roller-coordinated indentation structure described in Example 1. The cardboard to be indented is subjected to a first indentation when passing through a first indentation wheel 24 and a first rubber roller 4, and a second indentation when passing through a second indentation wheel 34 and a second rubber roller 5. The device can be equipped with a cutting structure and other processing to form a foldable cardboard, which is then folded into a carton.

[0067] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
