For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0024] See also Figure 1-4 The utility model provides an embodiment: a lateral movement device for lateral movement adjustment of a printing roller with a zero point, comprising a driving motor 1, a worm gear reduction box 2 is arranged above the driving motor 1, the output shaft of the driving motor is fixedly connected to the input shaft of the worm gear reduction box 2, and the output shaft of the worm gear reduction box 2 is fixedly connected to a lateral movement screw 3;
[0025] The worm gear reduction box 2 is mainly composed of a worm wheel or gear, a shaft, a bearing and a chassis, etc., and the worm wheel or gear, shaft and bearing are all supported by the chassis. Its main function is to reduce the speed of the drive motor 1. The worm gear reduction box 2 is a publicly available and mature existing equipment commonly used in the existing industrial field, and this specification does not repeat its working;
[0026] When used in the present invention, the driving motor 1 can be driven to rotate, and when the driving motor 1 rotates, the traverse screw 3 can be driven to rotate through the worm gear reducer 2, thereby providing necessary rotation conditions for subsequent thread traverse;
[0027] An encoder 4 is fixedly mounted on the outer wall of one side of the worm gear reducer 2, and the encoder 4 is fixedly connected to the tail end of the traverse screw 3;
[0028] The encoder is a device that compiles and converts signals or data into a signal form that can be used for communication, transmission and storage. It is a rotary sensor that converts rotational displacement into a series of digital pulse signals. These pulses can be used to control angular displacement. When used in the present utility model, the encoder 4 is combined with the traverse screw 3 to measure linear displacement, thereby helping outside staff to understand the displacement distance of the traverse adjustment in real time and effectively improve the adjustment accuracy;
[0029] The outer thread sleeve of the traverse screw rod 3 is provided with a traverse seat 5, the traverse seat 5 is threadedly connected with the traverse screw rod 3, a moving key 6 is fixedly installed on the outer wall of one side of the traverse seat 5, a traverse adjustment support 7 is provided on the outer cover of the traverse seat 5, a traverse groove 8 is opened on one side of the outer surface of the traverse seat 5, the moving key 6 is placed in the traverse groove 8, and the moving key 6 is slidably connected with the traverse groove 8;
[0030] This structural design can provide displacement space for the lateral movement of the moving key 6 through the transverse movement groove 8. At the same time, the transverse movement groove 8 can also guide and limit the movement of the transverse movement seat 5 below the moving key 6. It has a certain guiding effect and can limit and block the transverse movement seat 5, preventing the transverse movement seat 5 from rotating synchronously with the transverse movement screw rod 3, thereby ensuring a normal transmission transverse movement effect.
[0031] When the utility model is actually used, the outer end of the transverse shift seat 5 can be connected to the end of the printing roller. When the transverse shift screw 3 rotates, the transverse shift seat 5 thereon will move left and right on the transverse shift screw 3 (this effect depends on the forward and reverse rotation of the driving motor 1). In this way, the printing roller is driven to adjust the transverse shift through the left and right linear transverse shift of the transverse shift seat 5, thereby having an electrically adjustable screw drive adjustment effect. By controlling the number of rotations of the driving motor 1, the displacement adjustment amount of the transverse shift can be dynamically controlled, effectively improving the accuracy of the transverse shift adjustment of the printing roller. Compared with manual adjustment, the utility model has higher adjustment accuracy, good adjustment effect, fast adjustment speed, and good displacement accuracy, which can effectively improve the production quality and efficiency of printing work.
[0032] In this embodiment, in order to improve the structural stability, the lateral adjustment support 7 and the worm gear reduction box 2 are connected to each other through the outer bearing seat 9;
[0033] Among them, a cushion seat 12 is fixedly installed on the outer wall of the side of the transverse adjustment support 7 away from the worm gear reduction box 2.
[0034] In this embodiment, a bracket 10 is fixedly mounted on the outer wall of the cushion seat 12 close to the horizontal adjustment support 7;
[0035] Furthermore, photoelectric sensors 11 are fixedly mounted on both sides of the bracket 10, and the detection end of the photoelectric sensor 11 faces the moving key 6;
[0036] Among them, the photoelectric sensor 11 is a device that converts light signals into electrical signals. Its working principle is based on the photoelectric effect. The photoelectric effect refers to the phenomenon that when light irradiates certain substances, the electrons of the substances absorb the energy of photons and produce corresponding electrical effects. The photoelectric sensor realizes detection and control by converting the change of light intensity into the change of electrical signals. The photoelectric sensor 11 is a mature existing technology product, and this specification does not elaborate on its working principle in detail;
[0037] The photoelectric sensor 11 can be used to detect the position of an object. When used in the present invention, the photoelectric sensor 11 is electrically connected to the photoelectric detection system, which can respectively detect the position of the moving key 6 before and after the displacement. By changing the position of the moving key 6, the displacement of the lateral movement can be detected, which is convenient for the staff to understand the lateral movement distance in time. By using it in conjunction with the encoder, the accuracy of the lateral movement detection can be effectively improved, and the accuracy of the lateral movement adjustment can be effectively improved.
[0038] In this embodiment, a zero point limiting ring 13 is disposed inside the cushion seat 12, and a zero point probe 14 is fixedly installed outside the zero point limiting ring 13 and on the outer surface of the cushion seat 12;
[0039] The position of the zero point limit ring 13 can be detected by the zero point probe 14. In actual use, after the printing roller has hung the printing plate, it can be used as a basis for determining the starting point of printing, thereby having the effect of simultaneous zero point detection.
[0040] Working principle: When in use, the transverse shift adjustment device of the utility model is installed at one end of the printing roller, and the end of the printing roller is connected to the transverse shift seat 5 through a bearing (that is, when the printing roller rotates, the transverse shift seat 5 will not rotate with it, thereby ensuring the normal rotation of the printing roller);
[0041] When the printing roller needs to be adjusted laterally, the driving motor 1 can be used to rotate, and when the driving motor 1 rotates, the lateral movement screw 3 can be driven to rotate through the worm gear reducer 2;
[0042] When the traverse screw rod 3 rotates, the traverse seat 5 on it will move left and right on the traverse screw rod 3 (this effect depends on the forward and reverse rotation of the driving motor 1), so that the printing roller is driven to adjust the traverse through the left and right linear traverse of the traverse seat 5, thereby having an electrically driven adjustable screw rod drive adjustment effect, and the displacement adjustment amount of the traverse can be dynamically controlled by controlling the number of rotations of the driving motor 1, effectively improving the accuracy of the traverse adjustment of the printing roller. Compared with manual adjustment, the utility model has higher adjustment accuracy, good adjustment effect, fast adjustment speed, good displacement accuracy, and can effectively improve the production quality and efficiency of printing work;
[0043] In addition, the utility model connects an encoder 4 to the tail of the traverse screw rod 3, and the encoder 4 is combined with the traverse screw rod 3 to measure linear displacement data, thereby helping outside staff to understand the displacement distance of the traverse adjustment in real time, and effectively improving the adjustment accuracy;
[0044] In addition, a photoelectric sensor 11 is provided, which can be used to detect the position of an object. When used in the present invention, the photoelectric sensor 11 is electrically connected to the photoelectric detection system, which can respectively detect the position of the moving key 6 before and after the displacement. The position change of the moving key 6 can be used to detect the displacement of the lateral movement, which is convenient for the staff to understand the lateral movement distance in time. By using it in conjunction with the encoder 4, the accuracy of the lateral movement detection can be effectively improved, thereby further improving the lateral movement adjustment accuracy, and having a high-precision automatic lateral movement adjustment effect.
[0045] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
