Description

Technical Field

[0001] This utility model relates to the field of hose processing equipment technology, and in particular to a hose external support printing mechanism. Background Technology

[0002] In the production and processing of rubber hoses, in order to identify information such as specifications, model, manufacturer, and production date, it is usually necessary to print on the outer surface of the hose. Currently, the most common method of printing on rubber hoses in the industry is to directly attach the printing device to the outer surface of the hose. However, because the hose itself has a certain degree of elasticity, it is easy for the hose to deform or collapse during the printing process, resulting in unclear printing, distorted fonts, or even misalignment of the printing position, which seriously affects the product quality and appearance of the hose. Utility Model Content

[0003] The purpose of this utility model is to solve the problems in the prior art by proposing a rubber tube external support printing mechanism.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A hose external support printing mechanism includes a positioning block, and an opening mechanism is inserted inside the positioning block. The opening mechanism includes a guide plate, a fixed limiting rod, a limiting ring, and a return spring. The guide plate is inserted into the positioning block, the fixed limiting rod is fixedly disposed at the front end of the guide plate, the limiting ring is fixedly disposed on the outer wall of the fixed limiting rod, and the return spring is fixedly disposed at one end of the limiting ring.

[0006] Preferably, the spreading mechanism includes a movable limiting rod, which is fixedly disposed at the front end of the guide plate and located above the fixed limiting rod. Two limiting rings are provided, with the other limiting ring fixedly disposed on the outer wall of the movable limiting rod.

[0007] Preferably, the spreading mechanism includes a lower spreading member and a rubber tube member, wherein the lower spreading member is fixedly disposed at one end of the guide plate, and the rubber tube member is fixedly disposed at one end of the lower spreading member.

[0010] Preferably, the upper support member is located at the top of the lower support member, and both the lower support member and the upper support member are semi-circular structures.

[0011] Preferably, both the upper and lower support members are used to expand and support the hose fitting.

[0012] Preferably, the movable limiting rod is slidably disposed in the guide groove, and the positioning block includes a limiting insert plate and a baffle plate. The limiting insert plate is movably disposed in the limiting groove, and the baffle plate is fixedly disposed at one end of the limiting insert plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, by cooperating with the positioning block and the spreading mechanism, the upper spreading member and the lower spreading member are used to expand and support the rubber hose, which can effectively solve the problem of deformation or collapse of the rubber hose due to elasticity.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example, refer to Figures 1-5 A hose external support printing mechanism includes a positioning block 1, with a spreading mechanism inserted inside the positioning block 1. The spreading mechanism includes a guide plate 2, a fixed limiting rod 201, a limiting ring 2011, and a return spring 2012. The guide plate 2 is inserted into the positioning block 1, the fixed limiting rod 201 is fixedly disposed at the front end of the guide plate 2, the limiting ring 2011 is fixedly disposed on the outer wall of the fixed limiting rod 201, and the return spring 2012 is fixedly disposed at one end of the limiting ring 2011. The opening mechanism consists of a guide plate 2, a fixed limiting rod 201, a limiting ring 2011, and a return spring 2012. The guide plate 2 is inserted into the positioning block 1, the fixed limiting rod 201 is fixed to the front end of the guide plate 2, the limiting ring 2011 is fixed to the outer wall of the fixed limiting rod 201, and the return spring 2012 is fixed to one end of the limiting ring 2011. Through the cooperation of these components, the mechanism can provide basic support and initial positioning for the subsequent printing of the tube, thus avoiding large positional deviations of the tube during the initial placement stage.

[0024] Furthermore, the spreading mechanism includes a movable limiting rod 2013, which is fixedly installed at the front end of the guide plate 2 and located above the fixed limiting rod 201. Two limiting rings 2011 are provided, with the other limiting ring 2011 fixedly installed on the outer wall of the movable limiting rod 2013. The addition of the movable limiting rod 2013 to the spreading mechanism, which is fixed at the front end of the guide plate 2 and located above the fixed limiting rod 201, and the addition of two limiting rings 2011 with the other fixed on the outer wall of the movable limiting rod 2013, can further improve the limiting effect on each component of the spreading mechanism, enhance the overall stability of the mechanism, and better adapt to the hose support requirements.

[0025] Furthermore, the spreading mechanism includes a lower spreading member 2014 and a hose member 2015. The lower spreading member 2014 is fixedly disposed at one end of the guide plate 2, and the hose member 2015 is fixedly disposed at one end of the lower spreading member 2014. The addition of the lower spreading member 2014 and the hose member 2015 to the spreading mechanism, with the lower spreading member 2014 fixed at one end of the guide plate 2 and the hose member 2015 fixed at one end of the lower spreading member 2014, can effectively support the hose member 2015 through the lower spreading member 2014, providing a more fitting support structure for the hose and facilitating subsequent printing operations.

[0026] Furthermore, a guide mechanism is fixedly installed inside the positioning block 1. The guide mechanism includes a guide groove 101 and a limiting groove 1011. The guide groove 101 is longitudinally opened inside the positioning block 1, and the limiting groove 1011 is opened at one end of the positioning block 1. The guide mechanism is fixed inside the positioning block 1. The mechanism includes the guide groove 101 and the limiting groove 1011. The guide groove 101 is longitudinally opened inside the positioning block 1, and the limiting groove 1011 is opened at one end of the positioning block 1. The guide groove 101 can provide sliding guidance for related components, and the limiting groove 1011 can limit the components, ensuring that the movement of each component of the mechanism is orderly and improving the overall operational reliability.

[0027] Furthermore, the limiting groove 1011 is located at one end of the guide groove 101. The guide mechanism includes an upper support member 1012, which is fixedly disposed at one end of the positioning block 1. The limiting groove 1011 is located at one end of the guide groove 101. The guide mechanism adds the upper support member 1012 and fixes it at one end of the positioning block 1. The upper support member 1012 can cooperate with other components to further improve the support structure of the hose, enhance the support effect, and meet the support requirements of different hoses.

[0028] Furthermore, the upper support 1012 is located at the top of the lower support 2014. Both the lower support 2014 and the upper support 1012 are semi-circular structures. The upper support 1012 is located at the top of the lower support 2014, and both are semi-circular structures. The semi-circular structure design can better fit the outer contour of the hose, so that the upper support 1012 and the lower support 2014 can form a more comprehensive and stable wrapping support for the hose, reducing the risk of hose deformation.

[0029] Furthermore, both the upper support 1012 and the lower support 2014 are used to expand and support the rubber hose 2015. Through their synergistic effect, the rubber hose 2015 can be effectively expanded and supported, ensuring that the rubber hose 2015 maintains a stable shape during the printing process and avoiding problems such as unclear printing due to hose collapse.

[0030] Furthermore, the movable limiting rod 2013 is slidably disposed within the guide groove 101. The positioning block 1 includes a limiting insert plate 1013 and a baffle 1014. The limiting insert plate 1013 is movably disposed within the limiting groove 1011, and the baffle 1014 is fixedly disposed at one end of the limiting insert plate 1013. The movable limiting rod 2013 is slidably disposed within the guide groove 101. The positioning block 1 includes a limiting insert plate 1013 and a baffle 1014. The limiting insert plate 1013 is movably disposed within the limiting groove 1011, and the baffle 1014 is fixedly disposed at one end of the limiting insert plate 1013. The sliding of the movable limiting rod 2013 within the guide groove 101 allows for flexible adjustment of its position. The cooperation between the limiting insert plate 1013 and the baffle 1014 further strengthens the limiting of the mechanism components, ensuring the accuracy of the mechanism's operation and improving the printing quality.

[0031] In use, first insert the guide plate 2 in the spreading mechanism into the positioning block 1, so that the movable limit rod 2013 slides into the longitudinally opened guide groove 101 in the positioning block 1. At the same time, ensure that the fixed limit rod 201 and the limit ring 2011 on the outer wall of the movable limit rod 2013 are in the preset position. At this time, the reset spring 2012 fixed at one end of the limit ring 2011 is in a naturally extended state, providing a reset basis for the subsequent operation of the mechanism.

[0032] The rubber hose fitting 2015 to be printed is placed onto the lower support member 2014 of the support mechanism. The lower support member 2014 is fixed to one end of the guide plate 2. The lower support member 2014 provides initial support for the rubber hose fitting 2015 to prevent excessive displacement of the rubber hose fitting 2015 during placement.

[0033] Under the tension of the return spring 2012, the guide plate 2 is pushed to move along the guide path inside the positioning block 1, which drives the movable limit rod 2013 to slide in the guide groove 101. At the same time, the lower support member 2014 moves with the guide plate 2 and gradually moves away from the upper support member 1012 fixed at one end of the positioning block 1. Since the upper support member 1012 is located at the top of the lower support member 2014 and both are semi-circular structures, as the lower support member 2014 moves closer to the upper support member 1012, the two together form an expansion support for the sleeved hose 2015, so that the hose 2015 maintains a stable cylindrical shape.

[0034] When the hose fitting 2015 is expanded to fit the printing shape, the limiting plate 1013 of the positioning block 1 is movably inserted into the limiting groove 1011. The limiting groove 1011 is located at one end of the guide groove 101. The limiting plate 1013 restricts the sliding of the movable limiting rod 2013 in the guide groove 101, thereby fixing the position of the guide plate 2. At the same time, the baffle 1014 fixed at one end of the limiting plate 1013 can prevent the limiting plate 1013 from falling out of the limiting groove 1011, ensuring that the expansion mechanism provides stable support for the expansion of the hose fitting 2015.

[0035] While the hose fitting 2015 remains in a stable expanded state, the printing operation is performed. After printing is completed, the guide plate 2 is pushed upward using external cylinders or other equipment to release the restriction on the movable limit rod 2013. The return spring 2012 is compressed, and the limit ring 2011 drives the fixed limit rod 201 and the movable limit rod 2013 to reset, thereby resetting the guide plate 2 and the lower support 2014, no longer providing expansion support for the hose fitting 2015. At this point, the printed hose fitting 2015 can be removed.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
