Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of casing and pipe marking equipment, in particular to a collision-preventing machine head and casing and pipe marking equipment. BACKGROUND

[0002] When the casing and pipe is delivered, the specification parameter mark and coding mark are sprayed on the casing and pipe by the marking machine, so as to facilitate the on-site quick identification, matching use and production traceability.

[0003] After the casing and pipe is sprayed and printed along the flow line to the position below the printing station, it needs to be transferred by turning over. During the turning over and moving upward, the casing and pipe is prone to collide with the machine head of the marking equipment. The traditional machine head is usually fixedly installed by a steel plate, and the machine head will be damaged after collision.

[0004] Therefore, there is an urgent need for a marking equipment machine head which can avoid damage caused by collision. CONTENT OF THE UTILITY MODEL

[0005] In view of the above shortcomings of the prior art, the purpose of the present application is to provide a collision-preventing machine head and casing and pipe marking equipment, which aims to solve the problem that the existing casing and pipe collides with the machine head during turning over, resulting in damage to the machine head.

[0015] Another technical solution adopted by the application to solve the technical problem is a sleeve printing device, which comprises the anti-collision head according to any one of the above.

[0016] Compared with the prior art, the anti-collision head of the application is fixed by using the folding section that can be folded upward instead of a conventional steel plate, and the printing assembly is arranged below the folding section, so that the head is prevented from being damaged due to the collision of the oil sleeve, and when the oil sleeve collides with the head during the folding process, the folding section can be automatically folded upward and quickly reset under the action of gravity, so that the impact deformation of the original rigid structure is avoided, the service life of the device is fully improved, and the maintenance cost is reduced.

Therefore, the features defined with "first", "second" can be explicitly or implicitly included one or more. In the description of the application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0024] In the description of the application, it needs to be explained that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

[0025] During the turnover process of completing the jet printing, the oil casing will move upward and collide slightly with the jet printing head. When the jet printing head adopts the traditional steel plate connection, due to the influence of rigidity, the impact force of the collision will be completely absorbed by the head, causing the head to bend and damage, so that the jet printing assembly of the head cannot accurately aim at the position to be jet printed by the oil casing.

[0026] As Figure 1 and Figure 2As shown, the embodiment of the present application proposes a collision-proof head, which comprises a fixed seat 10, a fixed segment 11, a folding segment 12, a collision segment 13 and a printing assembly 14; the printing assembly 14 is connected to the lower position of the folding segment 12, the outer side wall of the fixed seat 10 is provided with the horizontally extending fixed segment 11, the folding segment 12 is rotationally connected with the fixed segment 11, and the end of the folding segment 12 away from the fixed segment 11 is provided with the collision segment 13; when the casing tube is upwardly displaced to collide with the collision segment 13, the folding segment 12 is upwardly folded. The middle part of the fixed seat 10 is provided with a through hole, which is used for penetrating and fixing the connecting rod which is extended and arranged on the oil jacket marking machine, the fixed segment 11 is a parallel arranged metal plate, which is integrally formed with the fixed seat 10 or is connected through screws, so that the relative position of the two is kept static, the upper surface of the folding segment 12 is flush with the fixed segment 11, so that the printing assembly 14 arranged at the lower position of the folding segment 12 can print the casing tube which passes through the oil jacket marking station, and the folding segment 12 can be upwardly folded by 0°-90°, so as to be slightly upwardly folded when colliding.

[0027] In the embodiment, the printing assembly 14 is arranged at the middle part of the lower position of the folding segment 12, and a certain horizontal distance is left between the printing assembly 14 and the collision segment 13, so as to avoid the collision part from extruding the printing assembly 14 when colliding.

[0028] Working principle: the oil jacket is conveyed to the printing assembly 14 through the assembly line to complete printing, and then the oil jacket is upwardly and obliquely folded by the folding mechanism, so that some oil jackets collide with the collision part, thereby driving the folding segment 12 and the printing assembly 14 connected thereto to be automatically upwardly folded, the effect of dynamic obstacle avoidance is realized, and the oil jacket marking station is returned under the action of gravity, so that the printing assembly 14 is always aligned with the oil jacket, and the damage of the head due to the collision between the oil jacket and the head is effectively avoided.

[0029] In one embodiment, the folding segment 12 is hingedly connected with the fixed segment 11 through a movable hinge 15, and the hinge is arranged at the upper position of the folding segment 12 and the fixed segment 11, so that the folding segment 12 is upwardly folded. The movable hinge 15 comprises a pair of fixed plates which are connected through a hinge, and the two fixed plates are respectively connected to the upper surfaces of the fixed segment 11 and the folding segment 12 through screws, and the folding segment 12 is kept static under the action of gravity and is upwardly folded when colliding.

[0030] In one embodiment, the collision segment 13 is a vertically arranged thin plate structure. Figure 1 As shown, the thin plate extends towards the side away from the folding segment 12, so as to ensure that the oil jacket first contacts the collision segment 13 when colliding.

[0031] In the embodiment, the collision segment 13 is a rectangular thin plate, and the long side direction of the rectangle is arranged in coincidence with the vertical direction. In one embodiment, the collision segment 13 is a vertically arranged thin plate structure.

[0032] In one embodiment, a guide surface 131 is provided on the side of the collision section 13 away from the folding section. The guide surface 131 is inclined relative to the horizontal plane and is configured as a curved surface. By providing the guide surface 131, the bottom of the collision section 13 is narrower and gradually expands outward to form a wider top. This prevents the oil casing from getting stuck at the bottom of the collision section 13 during impact. Instead, the material continues to fold upward along the guide surface 131, ensuring the smooth operation of the oil casing marking process.

[0033] In one embodiment, a collision avoidance block 16 is also included. The collision avoidance block 16 is disposed below the collision section 13 and / or on the outer side wall of the printing assembly 14. By providing the collision avoidance block 16, the direct impact of the oil sleeve on the printing head can be further avoided, which could cause damage to the printing head or leave damage on the oil sleeve.

[0034] In this embodiment, the anti-collision block 16 is made of an elastic material, such as rubber or silicone. The anti-collision block 16 is set on the lower side of the narrower collision section 13, which can effectively prevent the oil sleeve from impacting and denting the thin plate-shaped collision section 13. By setting the anti-collision block 16 on the outer wall of the printing assembly 14, the oil sleeve can be prevented from directly impacting the printing assembly 14 and causing damage to the printing assembly 14.

[0035] In one embodiment, a buffer block 17 is further provided between the folding section 12 and the printing assembly 14. The buffer block 17 is fixed between the folding section 12 and the printing assembly 14 by screws. By providing the buffer block 17, part of the impact force of the folding section 12 when it falls back is dissipated, preventing the printing assembly 14 from being damaged by rigid impact.

[0036] In one embodiment, a tension spring 18 is also included, which is connected to the fixed base 10 and the folding section 12 respectively. The tension spring 18 is configured such that the folding section 12 can fall back to the bottom at any angle after being folded up, so that the printing assembly 14 is reset to the predetermined position of the printing station after each impact.

[0037] In one embodiment, the fixing base 10 is provided with a movable clamp 19, which is used to fix the wire harness of the printing assembly 14. Since the printing assembly 14 is connected to the ink path and the circuit, when the folding section 12 is folded up, it will drive the ink path and the circuit connected to it, causing the wire harness to become entangled. By setting the movable clamp 19, the position of the wire harness can be more restricted, ensuring that the wire harness does not undergo large displacement during the folding and resetting process.

[0038] Another technical solution adopted by this application to solve the technical problem is a sleeve marking device, including an anti-collision head as described in any of the preceding claims. The beneficial effects of this sleeve marking device have been specifically described in the above description of the anti-collision head, and will not be repeated here.

[0039] This application embodiment uses an upward-flipping section instead of a traditional steel plate to fix the machine head. The printing component is set below the flipping section, which avoids damage to the machine head due to collision with the oil sleeve. When the oil sleeve collides with the machine head during the material turning process, the movable flipping section automatically flips up and quickly resets under the action of gravity, avoiding the impact deformation of the original rigid structure, greatly improving the service life of the equipment and reducing maintenance costs.

[0040] Adding a collision section in front of the folding section can prevent the oil sleeve from directly colliding with the printing assembly and the folding section, thus mitigating the impact force and further improving the stability of the printing head during collisions.

[0041] It should be understood that the application of this application is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
