Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of carton processing, and in particular relates to a cardboard pressing device. Background Art
[0002] Cartons are commonly used packaging products in the packaging industry. They are formed into cartons by pressing lines on the cardboard after die-cutting into the corresponding shape, and folding the cardboard along the pressing line. The depth of the pressing line is an important factor affecting the quality of carton molding. At present, in the carton production workshop, the die-cutting and pressing line processes of the cardboard are carried out automatically and continuously using corresponding equipment. However, with long-term operation, the surface of the pressing line wheel will be worn and deformed, and the gap between the upper and lower pressing lines will become larger, resulting in a small number of cardboards with shallow pressing line depths, which do not meet the requirements of carton molding. However, since the automated production line uses the corresponding equipment to directly send the cardboard out after die-cutting and pressing the line, even if the operator replaces and debugs it to meet the pressing line requirements, the cardboard with the pressing line depth that does not meet the requirements is difficult to be sent to the production line equipment again for secondary processing, and such cardboards with pressing lines that do not meet the requirements are a minority in the production line. If an independent fully automatic pressing line device in the prior art is configured for secondary processing, although it can quickly and accurately achieve the individual pressing line of the cardboard, the cost of the fully automatic pressing line device is relatively high. When applied to the cardboard with the pressing line depth that does not meet the requirements for secondary processing, the cost performance is low. Utility Model Content

[0004] The utility model includes a linear drive component and two wire pressing parts, the two wire pressing parts are arranged opposite to each other, an elastic component is arranged between the two wire pressing parts, and a support plate perpendicular to the wire pressing part is extended on one side of one of the wire pressing parts, a positioning plate for limiting the end of the paperboard is arranged on the support plate, and the linear drive component is used to drive the other wire pressing part to move toward the wire pressing part provided with the support plate, and the elastic component is compressed during the movement.
[0005] Furthermore, a guide hole is provided on one of the wire pressing parts, and a guide rod is provided on the other wire pressing part.

[0006] Furthermore, two guide rods are provided, which are located at the two ends of the wire pressing part where they are located; two guide holes are provided, which are located at the two ends of the wire pressing part where they are located, and the two guide rods are correspondingly inserted into the two guide holes.
[0007] Furthermore, the guide hole is a through hole, and the two ends of the spring are correspondingly abutted against the two wire pressing parts.
[0008] Furthermore, one end of the linear drive member is detachably connected to one of the wire pressing parts, and the other end is detachably connected to the other wire pressing part.
[0009] Furthermore, two linear drive members are provided, one end of the two linear drive members is detachably connected to the two sides of one of the wire pressing parts, and the other end is detachably connected to the two sides of the other wire pressing part, and the two linear drive members work synchronously.
[0010] Furthermore, when two guide rods are provided, two springs are correspondingly provided, and the two springs are correspondingly sleeved on the two guide rods.

[0013] Furthermore, it also includes a base, which is arranged at the bottom of the wire pressing part with the supporting plate.
[0014] The beneficial effect of the utility model is that when the cardboard is fed between the two pressing parts, the cardboard can be supported by the support plate to maintain its horizontal state, and the front end of the cardboard is limited by the positioning plate to ensure that the pressing position of the cardboard can accurately fall between the two pressing parts.

DETAILED DESCRIPTION
[0018] like Figure 1 and 2 As shown, the utility model includes two pressing parts 1, and the two pressing parts 1 are arranged opposite to each other. The two pressing parts 1 are provided with convex strips and grooves on the opposite sides thereof. When pressing, the cardboard is located between the two pressing parts 1. When the two pressing parts 1 are close to each other, the convex strips and grooves act on the surface of the cardboard to complete pressing. Among the two pressing parts 1, one side of one pressing part 1 is provided with a support plate 4 extending transversely and perpendicular to the direction of the line between the two pressing parts 1. The support plate 4 plays the role of supporting the cardboard. A positioning plate 5 for limiting the end of the cardboard is provided on the support plate 4, so as to position the cardboard to extend into the dimension between the two pressing parts 1. An elastic member 3 is provided between the two pressing parts 1. The elastic expansion and contraction direction of the elastic member 3 is in the same direction as the direction of the line between the two pressing parts 1. The elastic member 3 can be rubber or a spring.
[0019] The utility model further comprises a linear drive member 8, which is used to drive the crimping part 1 without the support plate 4 to move toward the crimping part 1 with the support plate 4, so that the two crimping parts 1 are close to each other to crimp the paperboard, and in this process, the elastic member 3 is compressed.
[0020] The utility model is based on the above-mentioned structural arrangement. In the use state, the two pressing parts 1 are arranged vertically, that is, the supporting plate 4 is arranged horizontally. The two pressing parts 1 are kept open at a certain interval by the linear driving member 8 so that the paperboard can be inserted. In combination with the arrangement of the supporting plate 4 and the positioning plate 5, when the paperboard is sent between the two pressing parts 1, the paperboard can be supported by the supporting plate 4 to maintain it in a horizontal state, and the front end of the paperboard is limited by the positioning plate 5 to ensure that the pressing position of the paperboard can accurately fall between the two pressing parts 1. The paperboard is directly inserted into the position between the two pressing parts 1 to ensure the accuracy of the pressing position, eliminate the pressing position error caused by naked eye observation, and can eliminate the cost of arranging sensors to detect the position of the paperboard. Then, the linear drive 8 drives the pressing part 1 without the support plate 4 to move downward, so that the two pressing parts 1 are close to each other, and the elastic part 3 is compressed at the same time. Based on the setting of the elastic part 3, when the conventional linear drive 8 is configured, the two pressing parts 1 are close to each other to play a certain buffering role when pressing the cardboard, and at the same time, it can effectively ensure that the minimum gap value of the two pressing parts 1 when pressing the cardboard meets the corresponding requirements, presses out the line marks with the required depth on the cardboard and avoids the cardboard surface from being crushed. The overall operation is convenient and fast, and can be effectively applied to the automated production line to perform fast and accurate secondary pressing processing on a small number of cardboards whose pressing depth does not meet the requirements, so as to avoid the cardboard surface from being cracked and make the cardboard pressing depth meet the requirements. The structure is relatively simple, the cost is relatively low, and the cost performance is higher.
[0021] The two wire pressing parts 1 are slidably connected to guide when the linear drive 8 drives the wire pressing part 1 without the support plate 4 to move. Specifically, a guide hole is provided on one of the wire pressing parts 1, and a guide rod 2 is provided on the other wire pressing part 1. The length direction of the guide rod 2 is in the same direction as the direction of the line between the two wire pressing parts 1. The guide rod 2 is inserted into the guide hole and slidably cooperates with the guide hole, so that the two wire pressing parts 1 are slidably connected. The elastic member 3 is preferably a spring, and the spring is sleeved on the guide rod 2. After the spring is compressed, it can have good rigidity and can effectively buffer. The spring is sleeved on the guide rod 2, and the elastic member 3 can be arranged in the outer area of the guide rod 2. The guide rod 2 is used to meet the sliding guidance requirements of the wire pressing part 1, and can also be used as a guide member when the spring is stretched and retracted, ensuring that the spring is compressed and stretched according to a straight path, thereby improving the stability and reliability of the utility model when used.
[0022] The guide hole is specifically a through hole, that is, it is set to pass through the wire pressing part 1, and the two ends of the spring are not connected to the two wire pressing parts 1, but directly contacted, and under the action of gravity, the spring is correspondingly abutted against the two wire pressing parts 1. This setting method can easily separate the two wire pressing parts 1, and the spring can be taken out according to the actual wire pressing needs, so as to replace the worn spring or replace the spring of different models according to the actual wire pressing requirements, and after assembly, it can also ensure normal sliding connection and normal use of the spring.
[0023] On this basis, the linear drive member 8 is arranged in such a manner that the linear drive member 8 is located on the side of the two wire-pressing parts 1, and one end of the two ends of the linear drive member 8 is detachably connected to one of the wire-pressing parts 1, and the other end is detachably connected to the other wire-pressing part 1. Specifically, connecting ear plates are arranged on the sides of the two wire-pressing parts 1, and one end of the linear drive member 8 is connected to the connecting ear plate on the side of one wire-pressing part 1 by bolts, and the other end is connected to the connecting ear plate on the side of the other wire-pressing part 1 by bolts, thereby realizing a detachable connection. When the two wire-pressing parts 1 need to be separated, the bolts can be removed. In this arrangement, the linear drive member 8 is directly installed using the two wire-pressing parts 1, and there is no need to arrange an additional bracket to fix the linear drive member 8.
[0024] Preferably, the linear drive members 8 are specifically provided with two, one end of the two linear drive members 8 is detachably connected to the two sides of one of the wire pressing parts 1, and the other end is detachably connected to the two sides of the other wire pressing part 1, and the two linear drive members 8 work synchronously to ensure the balance of the movement of the wire pressing part 1. That is, the sides of the two wire pressing parts 1 are provided with connecting ear plates, one end of the two linear drive members 8 is connected to the connecting ear plates on both sides of one wire pressing part 1 by bolts, and the other end is connected to the connecting ear plates on both sides of the other wire pressing part 1 by bolts, so as to achieve detachable connection.
[0025] In the present invention, the two linear drive members 8 are both cylinders, and the two ends of the linear drive member 8 are the piston rod end and the cylinder end of the cylinder. The two cylinders are connected to the solenoid valve 9 through the air pipe, the solenoid valve 9 is connected to the pressure regulating valve 10 through the air pipe, the pressure regulating valve 10 is connected to the external transformer gas station through the air pipe, and the solenoid valve 9 is electrically connected to the electric control box 11. Compared with other linear drive members, the cylinder can change the output pressure by adjusting the air pressure, which is convenient for adjusting the wire pressing force.
[0026] There are two guide rods 2, which are located at the two ends of the wire pressing part 1; there are two guide holes, which are located at the two ends of the wire pressing part 1. The two guide rods 2 are inserted into the two guide holes to ensure the stability of the wire pressing part 1 when sliding. When there are two guide rods 2, there are two springs, which are sleeved on the two guide rods 2, and the two ends of the two springs are in contact with the two wire pressing parts 1, so that the two ends of the wire pressing part 1 can be supported by the elastic force of the springs, ensuring the force balance at the two ends of the wire pressing part 1.
[0027] like Figure 1 and Figure 2 As shown, the two ends of the two wire pressing parts 1 are notched on one side opposite to each other, and the convex strips or grooves used for forming the wire pressing are located between the notched areas at both ends on the wire pressing part 1. Due to the setting of the notched areas, a step structure is formed between the two ends of the two wire pressing parts 1 and the convex strips or grooves, and the notched area forms a step surface 101. Two guide rods 2 are correspondingly arranged on the step surfaces 101 at both ends of one of the wire pressing parts 1, and two guide holes are correspondingly arranged on the step surfaces 101 at both ends of the other wire pressing part 1, and the two ends of the two springs are correspondingly abutted against the step surfaces 101 at both ends of the two wire pressing parts 1. Since the spring has a certain size, and the minimum gap between the two wire pressing parts 1 when pressing the wire is relatively small, the notched settings at both ends of the wire pressing part 1 can provide a certain assembly space for the spring, ensure that springs of corresponding sizes can be assembled, and provide a certain accommodation space for the spring in a compressed state.
[0028] The position of the positioning plate 5 on the support plate 4 is adjustable to adjust the distance between the positioning plate 5 and the two pressing parts 1, which not only facilitates the correction of the accuracy of the positioning plate 5, but also can adapt to the pressing of different paperboards within a certain size range.
[0029] Specifically, the support plate 4 is provided with a waist-shaped hole 401, the length direction of the waist-shaped hole 401 on the support plate 4 is perpendicular to the direction of the line connecting the two wire pressing parts 1, and the positioning plate 5 is provided with a mounting hole, and the fastener 6 is inserted in the mounting hole and the waist-shaped hole 401 to connect the positioning plate 5 and the support plate 4. The fastener 6 is specifically a bolt, and the bolt is locked by a nut after passing through the mounting hole and the waist-shaped hole 401. When the position of the positioning plate 5 needs to be adjusted, the nut is loosened, and the nut is tightened after the positioning plate 5 is moved. This setting method is simple in structure, easy to process, and easy to adjust.
[0030] The two wire pressing parts 1 are both made of stainless steel plates, which are easy to obtain and process. The utility model also includes a base 7, which is arranged at the bottom of the wire pressing part 1 with the support plate 4, and is used to support the entire device. When the base 7 is used to support the entire device, the wire pressing part 1 and the guide rod 2 are both arranged vertically, and the support plate 4 is arranged horizontally.
