Technical Field

[0001] This application relates to the technical field of collector gluing, and particularly relates to a combinable glue applicator roll. Background Art

[0002] When applying glue to the bottom coating of lithium electrode sheets, due to different specifications of the glue applicator rolls, the cost of manufacturing each type of glue applicator roll is very high, and the processing time is relatively long.

[0003] When applying glue to the bottom coating + coating of existing lithium electrode sheets, the glue applicator roll is customized according to the size of the electrode sheet. Because the size of the glue applicator roll needs to be determined according to the size of the electrode sheet during glue application, if there are many specifications, the cost will inevitably increase. In addition, the processing cycle is relatively long, which is time-consuming and laborious. Therefore, there is an urgent need for a glue applicator roll that can be freely combined. Utility Model Content

A second thread adapted to the outer part of the fixing sleeve is provided inside the reticulated sleeve, and the length of the reticulated sleeve is the same as that of the combined glue applicator roll.

[0007] By adopting the above technical solutions, the detachable coating smooth rolls are connected to the fixing sleeve through the first threads at both ends, so as to realize the connection between adjacent two coating smooth rolls. According to the length of the electrode sheet, different coating smooth rolls or combinations of coating smooth rolls are selected, and the fixing sleeve sleeved outside the coating smooth roll can be used to install the outer reticulated sleeve, meeting the stable connection between the reticulated sleeve corresponding to the size of the electrode sheet and the coating smooth roll.

[0009] By adopting the above technical solutions, the first threads at both ends of the coating smooth roll are respectively connected to the fixing nut, and the length of the fixing nut is equal to the length of the first threads on adjacent two coating smooth rolls, thereby improving the connection stability of the two coating smooth rolls.

[0010] Preferably, corresponding clamping grooves and clamping blocks are respectively provided on both end faces of the coating smooth roll, and the depth of the clamping groove is greater than the height of the clamping block.

[0011] By adopting the above technical solution, the end face of the coating light roller is connected through the cooperation of the clamping groove and the clamping block, further enhancing the stability of the connection between the two.

[0012] Preferably, a limiting strip is axially arranged inside the fixed sleeve, and a nut groove adapted to the fixed nut is provided at the end of the fixed sleeve. A limiting groove adapted to the limiting strip is formed on the coating light roller.

[0017] Preferably, the annular strip on the side of the baffle is made of an elastic rubber strip.

[0018] By adopting the above technical solution, a sleeve baffle is installed outside the fixed nuts at both ends of the anilox sleeve, which can limit the fixed sleeves and the anilox roller on both sides of the glue applicator roller, improving the stability of the installation of the fixed sleeves and the anilox roller on the surface of the coating light roller. And an anti-overflow mechanism is provided. The T-shaped baffle connected to the inner side of the baffle can be adapted to the annular groove on the anilox sleeve through the annular strip on its side.

The length of the reticulated sleeve 4 is the same as that of the combined glue - applying roller. The detachably - connected coating light rollers 1 are connected to the fixing sleeve 3 through the first threads 11 at both ends, so as to realize the connection between adjacent two coating light rollers 1. According to the length of the pole piece, different coating light rollers 1 or combinations of coating light rollers 1 are selected. And the fixing sleeve 3 sleeved outside the coating light roller 1 can be used to install the outer reticulated sleeve 4, meeting the stable connection between the reticulated sleeve 4 corresponding to the size of the pole piece and the coating light roller 1.

[0029] Referring to Figure 1 , Figure 2 and Figure 3, the first threads 11 at both ends of the coating light roller 1 are adapted to the internal threads of the fixing nuts 2, where the length of the first threads 11 along the axial direction of the coating light roller 1 is half of the length of the fixing nuts 2. The first threads 11 at both ends of the coating light roller 1 are respectively connected to the fixing nuts 2, and the length of the fixing nuts 2 is equal to the length of the first threads 11 on two adjacent coating light rollers 1, thereby improving the connection stability of the two coating light rollers 1.

The end face of the coating light roller 1 is connected through the cooperation of the clamping grooves 12 and the clamping blocks 13, further enhancing the connection stability between the two.

[0031] Refer to Figure 1 , Figure 2 and Figure 3 , a limiting strip 31 is axially provided inside the fixing sleeve 3, and a nut groove 33 adapted to the fixing nut 2 is provided at the end of the fixing sleeve 3. A limiting groove 32 adapted to the limiting strip 31 is provided on the coating light roller 1. The limiting strip 31 inside the fixing sleeve 3 can be adapted to the limiting groove 32 on the coating light roller 1 when the fixing sleeve 3 is sleeved on the coating light roller 1, thereby limiting the position of the fixing sleeve 3 on the coating light roller 1 and preventing the fixing sleeve 3 from rotating relative to the coating light roller 1.
