AI Technical Summary
During the cleaning process of the existing circular screen printing equipment, the connection strength between the stuffed head and the circular screen is insufficient, which leads to easy disengagement during the cleaning and separation process, and the use of the detachment agent is relatively wasteful.
A circular screen printing head suffix mechanism is designed, including the body, annular protrusion, a groove, accommodating groove and an end cap. By applying glue in the groove, the contact area between the glue and the annular protrusion is increased to ensure a secure connection between the round net and the head; when separation, the release agent is fully in contact with the glue through the accommodating groove and the small hole, so as to dissolve the glue to achieve effective separation between the head and the round net.
The connection strength between the round net and the stuffed head is improved, the risk of disengagement during the cleaning process is reduced, and the waste of resources is reduced by more effective use of the disengagement agent, and it has high economic benefits.

Abstract
Description
Technical Field
[0001] The utility model relates to printing equipment, more specifically, it relates to a rotary screen printing head mechanism. Background Art
[0002] The rotary screen printing machine is a screen printing machine that uses a continuously rotating seamless rotary screen for printing. The surface of the rotary screen is coated with photosensitive glue, which will form the desired pattern after processes such as exposure and glue washing. The pigment is injected into the interior of the rotary screen, and then the scraper inside the rotary screen squeezes the pigment out of the pattern on the surface of the rotary screen, so that it forms a pattern on the fabric that is the same as the pattern, thereby completing the printing work.
[0003] After a printing job is completed, when the pattern on the surface of the rotary screen needs to be replaced, a rotary screen cleaning machine will be used. The rotary screen cleaning machine contains a blind head for installation at both ends of the rotary screen. The blind head is usually installed on the inner wall of the end of the rotary screen, and then the rotary screen is installed in the rotary screen cleaning machine by applying torque to the blind head. Then a high-pressure water jet is used to clean the photosensitive adhesive on the surface of the rotary screen. In this process, in order to ensure the connection strength between the blind head and the inner wall of the rotary screen, glue is usually added to the contact point between the blind head and the rotary screen. After the cleaning process is completed, the blind head and the rotary screen need to be separated by soaking in a release agent. The soaking requires the rotary screen and the blind head to be placed in a separation tank containing a release agent. More release agent needs to be poured into the separation tank to completely immerse the rotary screen and the blind head, and the release agent is only used to react with the glue at the connection between the blind head and the rotary screen, which makes the use of the release agent more wasteful.
[0004] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content
[0005] In view of the shortcomings of the prior art, the utility model aims to provide a rotary screen printing head mechanism.
[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a rotary screen printing head mechanism, including a main body, one end of the main body is provided with an annular protrusion for being sleeved on the inner circumferential wall of the rotary screen, a plurality of grooves are provided on the outer circumferential wall of the annular protrusion, and an accommodating groove for accommodating a release agent is provided at the end of the main body facing away from the annular protrusion, small holes connected to the accommodating groove are provided on the bottom wall of the groove and the top wall of the annular protrusion, and an end cover for closing the accommodating groove is also detachably connected to the main body.
[0007] The utility model is further configured as follows: an inner circumferential wall of the containing groove is provided with an internal thread, an external thread for matching with the internal thread is provided on the end cover, and a sealing member for preventing the release agent from overflowing is provided between the end cover and the body.
[0008] The utility model is further configured as follows: the sealing member is a rubber ring, and the end cover is provided with a recess for being embedded by the rubber ring.
[0009] The utility model is further configured as follows: a gripping block is provided at one end of the end cover facing away from the body.
[0010] The utility model is further configured as follows: the outer edge of the body is also provided with a stop ring for contacting with the end of the round net.
[0011] The utility model is further configured as follows: the body is made of stainless steel.
[0012] In summary, the utility model has the following beneficial effects: when it is necessary to use a round screen cleaning machine to clean the photosensitive adhesive cured on the round screen, first apply glue in the groove, and then embed the annular protrusion in the end of the round screen. The opening of the groove can better accommodate the glue and indirectly increase the contact area between the glue and the annular protrusion, so that the bonding effect of the glue is relatively reliable, so that the round screen is not easy to separate from the blind head during the cleaning process. When performing the operation of separating the round screen from the blind head, the operator can remove the end cover from the main body, and then inject a release agent into the receiving groove. After the injection is completed, the receiving groove is closed with the end cover. At this time, the release agent is fully in contact with the glue through the small holes, so that the release agent can better dissolve the glue, thereby completing the separation of the blind head and the round screen. Compared with pouring the release agent into the separation tank, this method requires less release agent, so that the release agent can be used more fully, with higher economic benefits.

[0016] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.
[0017] Rotary screen printing head mechanism, such as Figure 1 and Figure 2As shown, it includes a body 1, one end of the body 1 is provided with an annular protrusion 2 for being sleeved on the inner circumferential wall of the round net, and the outer circumferential wall of the annular protrusion 2 is provided with a plurality of grooves 3, and the end of the body 1 facing away from the annular protrusion 2 is provided with a receiving groove 4 for accommodating a release agent, and the bottom wall of the groove 3 and the top wall of the annular protrusion 2 are both provided with small holes 5 connected with the receiving groove 4, and the body 1 is also detachably connected with an end cover 6 for closing the receiving groove 4. When it is necessary to use a round net cleaning machine to clean the photosensitive adhesive cured on the round net, glue is first applied to the groove 3, and then the annular protrusion 2 is embedded in the end of the round net. The opening of the groove 3 can better accommodate the glue and indirectly increase the glue The contact area between water and the annular protrusion 2 makes the bonding effect of the glue more reliable, so that the round screen is not easy to separate from the blind head during the cleaning process. When performing the operation of separating the round screen from the blind head, the operator can remove the end cover 6 from the main body 1, and then inject the release agent into the receiving groove 4. After the injection is completed, the receiving groove 4 is closed with the end cover 6. At this time, the release agent is in full contact with the glue through the small hole 5, so that the release agent can better dissolve the glue, thereby completing the separation of the blind head and the round screen. Compared with pouring the release agent into the separation tank, this method requires less release agent, so that the release agent can be used more fully, with higher economic benefits.
[0018] like Figure 2As shown, an internal thread is provided on the inner peripheral wall of the receiving groove 4, and an external thread for matching with the internal thread is provided on the end cover 6. The rotation direction of the internal thread is opposite to the rotation direction of the round screen cleaning machine. A sealing member 7 for preventing the release agent from overflowing is provided between the end cover 6 and the body 1. After the photosensitive glue on the body 1 is cleaned, before the release agent is injected into the receiving groove 4, the end cover 6 is unscrewed from the body 1, and the release agent is poured into the receiving groove 4. After the release agent is injected, the screw cap is screwed back on the body 1, and part of the release agent overflows through the small hole 5 to react with the glue. When the release agent at the outside reacts more with the glue, the screw cap can be further moved toward the body 1. Screw it in, so that more release agent that has not participated in the reaction seeps out from the small hole 5 and reacts with the glue, so that the release agent can be fully utilized. The end cover 6 and the body 1 are fixed more firmly through the threaded connection. In addition, the rotation direction of the internal thread is set opposite to the rotation direction of the round screen cleaning machine, so that when the round screen cleaning machine is running, it is not easy for the end cover 6 and the body 1 to rotate relative to each other, so that the operation of the round screen cleaning machine will not affect the connection strength between the end cover 6 and the body 1. The setting of the sealing member 7 makes it difficult for the release agent to leak out from the gap between the end cover 6 and the body 1, and better ensures the sealing of the connection between the end cover 6 and the body 1. The sealing member 7 is a rubber ring. The end cover 6 is provided with a depression for embedding the rubber ring. The rubber ring has good deformation ability. The rubber ring is used as the seal 7, so that the seal 7 can be deformed along the inner wall of the receiving groove 4, so that the seal 7 can better fill the gap between the end cover 6 and the inner wall of the receiving groove 4. The opening of the depression makes it difficult for the rubber ring to fall off the end cover 6. A gripping block 8 is provided at one end of the end cover 6 facing away from the body 1. The number of the gripping blocks 8 is three. The three gripping blocks 8 are distributed in a circular array with the center of the end cover 6 as the axis. The setting of the gripping blocks 8 provides the operator with a better force point when disassembling and installing the end cover 6, so that the disassembly and assembly of the end cover 6 is more convenient. At the same time, when the blind head is installed on the round screen cleaning machine, the three gripping blocks 8 on the end cover 6 can also cooperate well with the three-jaw chuck on the round screen cleaning machine, which facilitates the installation of the blind head on the round screen cleaning machine. The outer edge of the main body 1 is also provided with a stop ring 9 for contacting the end of the round screen. The setting of the stop ring 9 makes the end of the round screen contact with the stop ring 9 when the main body 1 is embedded in the end of the round screen, so that the main body 1 will not be too embedded in the end of the round screen. The main body 1 is made of stainless steel, which has good corrosion resistance. The main body 1 made of stainless steel can better adapt to the environment full of release agent, so that the main body 1 has a longer service life.
