Description

Technical Field

[0001] This utility model belongs to the field of printing and packaging machinery technology, specifically a shock-absorbing aluminum roller with a buffer device. Background Technology

[0002] Aluminum rollers are cylindrical rollers made primarily of aluminum alloy. They are widely used in various fields of industrial production and play an important role in various mechanical equipment due to their unique performance advantages. In the printing and packaging machinery field, they are used for conveying and guiding paper and film. The high-precision surface ensures smooth material movement and avoids wrinkles or deviations. Some aluminum rollers can be designed as heated rollers (with internal hot oil or steam) for use in the drying process after printing.

[0003] However, the following problems were found in the implementation of the relevant technologies:

[0004] In existing technologies, when aluminum rollers come into contact with workpieces, there is generally a lack of effective cushioning design. Most aluminum rollers make direct, rigid contact with the workpiece, and the impact force between the workpiece and the aluminum roller cannot be buffered during operation. This not only easily leaves defects such as indentations and scratches on the workpiece surface, affecting the surface quality of the workpiece, but also causes the aluminum roller itself to be subjected to large impact forces for a long time, leading to accelerated wear on the surface of the aluminum roller and shortening its service life.

[0005] Moreover, the existing aluminum rollers do not provide precise guidance for the lifting plate in terms of the lifting structure. During the lifting process, the lifting plate is prone to deviation, which causes the aluminum rollers to be unstable in position during operation. This threatens the structural stability of the equipment and may even lead to loosening or damage of equipment parts, increasing the probability of equipment failure. Utility Model Content

[0006] To address the problems mentioned in the background section, this invention provides a shock-absorbing aluminum roller with a buffer device, which offers advantages such as good buffering effect and stable operation. This invention utilizes the cooperation of a spring and a lifting column to form an elastic buffer, solving the problem of workpiece damage and roller wear caused by hard contact between the aluminum roller and the workpiece in the prior art. Furthermore, through precise guidance by the positioning column and vibration reduction by the elastic damping ring, it solves the problems of easy displacement of the lifting plate and large vibrations during aluminum roller rotation affecting operational stability.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a shock-absorbing aluminum roller with a buffer device, comprising a table, two aluminum roller bodies on the upper surface of the table, L-shaped frames symmetrically fixed on the upper surface of the table, and a gantry frame fixedly fixed on the inner side of the two L-shaped frames, and a cylinder fixedly fixed on the upper surface of the gantry frame, the output end of the cylinder passing through the gantry frame and fixedly mounted on a lifting plate, support plates symmetrically fixed on both sides of the upper surface of the lifting plate, and the aluminum roller body located directly below the corresponding support plate.

[0008] Preferably, sleeves are symmetrically fixed on both sides of the lower surface of the support plate, and lifting columns are movably inserted into the sleeves and the lower surface of the support plate. The lower end of the lifting column is detachably provided with a support seat. The aluminum roller body is rotatably disposed between two corresponding support seats, and a spring is fixedly connected between the support seat and the corresponding sleeve.

[0009] Preferably, positioning columns are symmetrically fixed on both sides of the upper surface of the lifting plate, and the positioning columns penetrate the gantry frame.

[0010] Preferably, elastic damping rings are fitted at the connection points between both ends of the aluminum roller body and the support base, and the inner ring of the elastic damping ring is tightly fitted with the end of the aluminum roller body, while the outer ring is tightly fitted with the inner sidewall of the support base.

[0011] Preferably, the spring is wound around the outer surface of the corresponding lifting column.

[0012] Preferably, the lower surface of the lifting column is connected to the support base by bolts.

[0013] Preferably, the lower surface of the tabletop is symmetrically provided with support legs.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, the device includes a table 1, with two aluminum roller bodies 46 on the upper surface of the table 1. An L-shaped frame 2 is symmetrically fixed to the upper surface of the table 1, and a gantry frame 41 is fixed to the inner sides of the two L-shaped frames 2. A cylinder 42 is fixed to the upper surface of the gantry frame 41, with the output end of the cylinder 42 passing through the gantry frame 41 and fixed to a lifting plate 43. Support plates 45 are symmetrically fixed to both sides of the upper surface of the lifting plate 43. The aluminum roller bodies 46 are located directly below the corresponding support plates 45. The L-shaped frames 2 symmetrically fixed to the upper surface of the table 1 jointly support and fix the gantry frame 41, ensuring a stable installation posture for the gantry frame 41. The cylinder 42 is fixed to the upper surface of the gantry frame 41. When the cylinder 42 operates, its output end drives the lifting plate 43 to move up and down.

[0024] Specifically, sleeves 48 are symmetrically fixed on both sides of the lower surface of the support plate 45, and lifting columns 47 are movably inserted into both the sleeves 48 and the lower surface of the support plate 45. A support seat 49 is detachably provided at the lower end of the lifting column 47. The aluminum roller body 46 is rotatably positioned between the two corresponding support seats 49. A spring 410 is fixedly connected between the support seat 49 and the corresponding sleeve 48. The support plates 45 on both sides of the upper surface of the lifting plate 43 are used to install the sleeves 48. The lifting column 47 is movably inserted into both the lower surface of the sleeves 48 and the support plate 45, allowing the lifting column 47 to move up and down relative to the sleeves 48 and the support plate 45. The lower end of the lifting column 47 is connected via... The bolt is detachably connected to the support base 49. The aluminum roller body 46 is rotatably positioned between the two corresponding support bases 49. Therefore, the aluminum roller body 46 can move up and down with the support base 49 and the lifting column 47 along with the lifting plate 43. When the aluminum roller body 46 contacts the workpiece on the table 1, the workpiece exerts an upward force on the aluminum roller body 46. This force is transmitted to the lifting column 47 through the support base 49, causing the lifting column 47 to compress the spring 410 (spring 410 is wrapped around the outer surface of the lifting column 47) between the support base 49 and the sleeve 48. The elastic deformation of the spring 410 generates a reverse force, thus buffering the aluminum roller body 46.

[0025] Furthermore, positioning posts 44 are symmetrically fixed on both sides of the upper surface of the lifting plate 43, and the positioning posts 44 penetrate the gantry frame 41. The positioning posts 44 symmetrically fixed on both sides of the upper surface of the lifting plate 43 penetrate the gantry frame 41, and play a guiding and limiting role during the lifting process of the lifting plate 43, so as to ensure that the lifting plate 43 moves stably without deviation.

[0026] Furthermore, elastic damping rings are fitted at the connection points between both ends of the aluminum roller body 46 and the support base 49. The inner ring of the elastic damping ring is tightly fitted to the end of the aluminum roller body 46, and the outer ring is tightly fitted to the inner side wall of the support base 49. The elastic damping rings fitted at the connection points between both ends of the aluminum roller body 46 and the support base 49 can reduce the vibration transmission when the aluminum roller body 46 rotates, and ensure the stable rotation of the aluminum roller body 46.

[0027] It is worth noting that the lower surface of the lifting column 47 is connected to the support base 49 by bolts, and the lower end of the lifting column 47 is detachably connected to the support base 49 by bolts.

[0028] It is worth mentioning that the lower surface of the table 1 is symmetrically fixed with support legs 3. The table 1 provides the installation base for the entire device, and the support legs 3 symmetrically fixed on its lower surface play a role in stabilizing and supporting the table 1.

[0029] Among them, cylinder 42 is prior art and will not be described in detail; at the same time, this utility model also includes a power supply, controller and switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0030] Working principle: The tabletop 1 provides the installation foundation for the entire device, and the symmetrically fixed support legs 3 on its lower surface provide stable support for the tabletop 1. The symmetrically fixed L-shaped frames 2 on the upper surface of the tabletop 1 together support and fix the gantry frame 41, so that the gantry frame 41 maintains a stable installation posture;

[0031] A cylinder 42 is fixed on the upper surface of the gantry frame 41. When the cylinder 42 works, its output end will drive the lifting plate 43 to move up and down. The positioning columns 44, which are symmetrically fixed on both sides of the upper surface of the lifting plate 43, pass through the gantry frame 41 and play a guiding and limiting role during the lifting process of the lifting plate 43, ensuring that the lifting plate 43 moves stably without deviation.

[0032] The support plates 45 on both sides of the upper surface of the lifting plate 43 are used to install the sleeve 48. The lower surfaces of the sleeve 48 and the support plate 45 are movably inserted with the lifting column 47, so that the lifting column 47 can move up and down relative to the sleeve 48 and the support plate 45. The lower end of the lifting column 47 is detachably connected to the support seat 49 by bolts. The aluminum roller body 46 is rotatably set between the two corresponding support seats 49. Therefore, the aluminum roller body 46 can move up and down with the lifting plate 43 along with the support seat 49 and the lifting column 47.

[0033] When the aluminum roller body 46 contacts the workpiece on the table 1, the workpiece exerts an upward force on the aluminum roller body 46. This force is transmitted to the lifting column 47 through the support seat 49, causing the lifting column 47 to compress the spring 410 (spring 410 is wrapped around the outer surface of the lifting column 47) between the support seat 49 and the sleeve 48. The elastic deformation of the spring 410 generates a reverse force, thus buffering the aluminum roller body 46. At the same time, the elastic damping rings fitted at the connection between the aluminum roller body 46 and the support seat 49 at both ends can reduce the vibration transmission when the aluminum roller body 46 rotates, ensuring the stable rotation of the aluminum roller body 46.
