[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] As Figures 1 to 4 shown, the present invention provides a PE film printing and coating integrated machine, which includes a plurality of printing plates 4. A printing roller 2 is arranged between the plurality of printing plates 4. Three adjusting and positioning components 5 are fixedly connected to the bottom of the printing plate 4 and are evenly distributed outside the printing roller 2. The other ends of the adjusting and positioning components 5 at the bottom of the plurality of printing plates 4 are fixedly connected to the outer surface of the printing roller 2. A positioning roller 1 is arranged above the printing plate 4. A PE film 3 is arranged at the bottom of the positioning roller 1, and the bottom of the PE film 3 contacts the top of the printing plate 4. Due to the arrangement of the adjusting and positioning components 5, the length of the adjusting and positioning components 5 can be conveniently adjusted with the cooperation of the left and right adjusting components 23, so as to change the distance between the printing plate 4 and the printing roller 2, that is, to achieve the purpose of changing the distance between two adjacent printing plates 4, thereby achieving the effect of adjusting the distance between two adjacent coating prints on the surface of the PE film 3 in continuous printing.

[0026] The printing roller 2 includes a printing driving roller 21 fixedly connected between a plurality of adjusting and positioning components 5. A plurality of through holes 22 are formed in the middle of the printing driving roller 21. The plurality of through holes 22 correspond to the printing plates 4 one by one. The through holes 22 are communicated with one of the adjusting and positioning components 5 in the middle of each printing plate 4. Both ends of the printing driving roller 21 are connected with an adjusting component 23. One of the adjusting components 23 continuously injects air into the printing driving roller 21, and the other adjusting component 23 continuously extracts the air in the printing driving roller 21. Mounting bearings 24 are fixedly sleeved on both ends of the outer surface of the printing driving roller 21. Due to the arrangement of the printing roller 2, the distance between two adjacent printing plates 4 can be adjusted in cooperation with the adjusting and positioning components 5, and at the same time, it is also convenient to adjust the distance between the printing roller 2 and the positioning roller 1, that is, the distance between the top of the printing plate 4 and the positioning roller 1 can be changed, so as to achieve the effect of being applicable to PE films of different thicknesses.

[0027] Among them, an ink transfer roller 6 is arranged below the printing plate 4, and the top of the ink transfer roller 6 contacts the bottom of the printing plate 4. Support frames are arranged at the front and rear ends of the printing plate 4. The positioning roller 1 is fixedly installed on the support frames through a rotating shaft. The ink transfer roller 6 and the printing driving roller 21 are slidably clamped on the support frames through the mounting bearings 24 on their outer surfaces, and the printing roller 2 and the ink transfer roller 6 move up and down along the support frames.

[0028] Among them, the adjustment and positioning component 5 includes a limit tube sleeve 51 fixedly connected to the outer surface of the printing drive roller 21. A positioning slide rod 52 is movably sleeved inside the limit tube sleeve 51. The upper end of the positioning slide rod 52 extends outside the limit tube sleeve 51 and is connected to the printing plate 4.

[0029] One limit tube sleeve 51 connected to the middle of each printing plate 4 is communicated with the inside of the printing drive roller 21 through a through hole 22. The limit tube sleeve 51 and the positioning slide rod 52 inside it are sealingly sleeved. There is a gap between the other two limit tube sleeves 51 and the positioning slide rods 52 inside them. A positioning spring 53 is arranged inside the limit tube sleeve 51. The upper end of the positioning spring 53 is connected to the upper end of the inner cavity of the limit tube sleeve 51, and the lower end of the positioning spring 53 is connected to the lower end of the positioning slide rod 52. Due to the setting of the adjustment and positioning component 5 in the middle of each printing plate 4, with the cooperation of the through hole 22, the adjustment component 23 can adjust the internal air pressure through the printing drive roller 21, thereby changing the distance between the printing plate 4 and the printing roller 2. And due to the setting of the two adjustment and positioning components 5 at both ends of each printing plate 4, it can play a good limiting effect on the movement of the printing plate 4, enabling the printing plate 4 to move smoothly to ensure that its top can be closely attached to the PE film 3.

[0030] Among them, the printing plate 4 includes a detachable coating and printing plate 41 arranged at the outer end of the adjustment and positioning component 5. A clamping block 42 is arranged between the detachable coating and printing plate 41 and the adjustment and positioning component 5. The clamping block 42 is fixedly installed at the outer end of the positioning slide rod 52. A clamping strip 43 is slidably clamped inside the clamping block 42. The outer side of the clamping strip 43 is fixedly connected to the bottom of the detachable coating and printing plate 41. Due to the setting of the printing plate 4, with the cooperation of the clamping block 42 and the clamping strip 43, the detachable coating and printing plate 41 can be fixed to the outer end of the adjustment and positioning component 5, and at the same time, it is also convenient to replace the detachable coating and printing plate 41, greatly reducing the difficulty of replacing the coating and printing roller and effectively improving work efficiency.

[0031] Among them, the adjustment component 23 includes a transmission shaft 231 inserted into both ends of the printing drive roller 21. A transmission wheel 232 located outside the printing drive roller 21 is fixedly sleeved on the outer surface of the transmission shaft 231. The cross-section of the outer surface of the transmission shaft 231 is polygonal. The transmission wheel 232 drives the printing drive roller 21 to rotate through the transmission shaft 231. Due to the setting of the transmission shaft 231, when the driving mechanism drives the transmission wheel 232 to rotate through the transmission belt, the printing drive roller 21 can be driven to rotate through the transmission shaft 231.

[0032] Among them, an adjustment cavity 233 is formed inside the transmission shaft 231. At one end of the adjustment cavity 233 away from the printing transmission roller 21, an adjustment piston 234 is hermetically sleeved. On the side of the outer surface of the adjustment piston 234 close to the printing transmission roller 21, a return spring 235 located inside the adjustment cavity 233 is connected. Due to the arrangement of the adjustment piston 234, when it moves, it can continuously compress the air inside the adjustment cavity 233 with the cooperation of the return spring 235, causing the air pressure inside the adjustment cavity 233 to change continuously.

[0033] On the other side of the adjustment piston 234, a connecting rod 236 is fixedly connected. The connecting rod 236 is movably sleeved inside the transmission shaft 231, and the other end of the connecting rod 236 extends outside the transmission shaft 231 and is fixedly connected with an adjustment block 237.

[0034] Among them, an air injection valve 238 is arranged at one end of the adjustment cavity 233 close to the printing transmission roller 21. The adjustment cavity 233 is communicated with the printing transmission roller 21 through the air injection valve 238. A plurality of air inlet valves 239 evenly distributed around the adjustment cavity 233 are formed inside the transmission shaft 231. One end of the air inlet valve 239 is communicated with the adjustment cavity 233, and the other end of the air inlet valve 239 is communicated with the outside of the printing roller 2. Due to the arrangement of the air injection valve 238 and the air inlet valves 239, when the air pressure inside the adjustment cavity 233 changes, the external air can be made to flow mutually with the air inside the printing transmission roller 21. Furthermore, through the two left and right adjustment assemblies 23, the external air pressure can be injected into the printing transmission roller 21, or the air pressure inside the printing transmission roller 21 can be extracted, so as to achieve the effect of adjusting the length of the adjustment positioning assembly 5 in cooperation with the through holes 22.

[0035] The working principle and usage process of the present utility model:

[0036] As shown in the assembly equipment, according to the thickness of the PE film 3 and the printing requirements, adjust the distance between the printing roller 2 and the printing plate 4 and the positioning roller 1, that is, move the printing roller 2 up and down, which can drive a plurality of printing plates 4 to move up and down, so that the distance between the top of the printing plate 4 on the outer side of the printing roller 2 and the positioning roller 1 is suitable for clamping the PE film 3. Furthermore, after starting, the pattern on the surface of the detachable coating printing plate 41 can be transferred to the bottom of the PE film 3.

[0037] The detachable coating printing plate 41 can be replaced with the cooperation of the clamping block 42 and the clamping strip 43, so as to facilitate printing different patterns.

[0038] After moving the printing roller 2, through the two left and right adjustment assemblies 23, the distance between a plurality of printing plates 4 relative to the printing roller 2 can be adjusted with the cooperation of the adjustment positioning assembly 5, so as to change the spacing between the patterns printed on the PE film 3 by adjacent detachable coating printing plates 41.

[0039] That is, reciprocally pull the adjusting block 237, and drive the adjusting piston 234 through the connecting rod 236 to slide left and right along the inside of the adjusting cavity 233, so that the return spring 235 is repeatedly compressed; and under the cooperation of the air injection valve 238 and the air inlet valve 239, the air pressure inside the printing driving roller 21 is continuously changed, and then the air pressure at the bottom of the positioning slide rod 52 in the limiting bushing 51 is changed through the through hole 22. Then, under the cooperation of the limiting bushing 51 and the positioning spring 53, the positioning slide rod 52 moves along the inside of the limiting bushing 51, so that the length of the adjusting and positioning assembly 5 can be changed, and then the distance between the printing plate 4 and the printing roller 2 can be changed, so that the distance between two adjacent detachable coating printing plates 41 is changed;

[0040] Finally, start the driving mechanism, and the driving belt can drive the driving wheel 232 to rotate. The rotation of the driving wheel 232 can drive the printing driving roller 21 to rotate through the transmission shaft 231 under the support of the mounting bearing 24, so that a plurality of detachable coating printing plates 41 around it are successively in contact with the bottom of the PE film 3.

[0041] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprises", "comprising" or any other variation thereof is intended to cover a non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
