Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aluminum-plastic film production, in particular to an aluminum-plastic film production equipment with double-sided coating function and a production method thereof. BACKGROUND

[0002] Aluminum-plastic film products have excellent flexibility, and also have many superior properties such as oxygen barrier, moisture resistance, light shielding, and anti-static. As electronic product-related lithium batteries, they are widely used in various small digital products due to their high energy density and excellent high and low temperature environment adaptability. With the continuous increase of electronic product types, the production requirements for lithium batteries are becoming higher and higher, and the packaging of lithium batteries is gradually replaced from aluminum shells and hard steel shells to soft aluminum-plastic films.

[0003] In the production process of battery aluminum-plastic film, a layer of special functional paste needs to be coated on the surface of the coiled base material aluminum foil to ensure that the surface is flat, smooth, evenly coated, and has good adhesion, and after drying, it does not fall off, does not drop, has no dust accumulation and no bubbles. The conventional method is to coat both sides separately, and to coat twice on the same equipment, which has low overall production efficiency and slow production speed, and the product turnover period is too large, which seriously affects the production progress. SUMMARY

[0005] In order to solve the above technical problems, the present application provides the following technical scheme: an aluminum-plastic film production equipment with double-sided coating function, the production equipment comprises a bottom plate, an oven, a supporting frame is installed above the bottom plate, an upper plate is rotatably installed above the supporting frame, a platform is installed below the oven, one end of the platform is installed on the bottom plate through a supporting leg, two blocking plates are arranged inside the oven, the blocking plates divide the internal space of the oven into a coating bin and a heating bin, an aluminum foil roll is placed on the upper plate, the aluminum foil passes through the coating bin and the heating bin in sequence, two coating rollers are arranged in the coating bin, a heating roller is arranged in the heating bin, two discharge rollers are installed at one end of the oven, and the discharge rollers convey the aluminum foil.

[0006] The feeding plate comprises a sleeve and two inner plates installed in the sleeve, both ends of the inner plate and the sleeve are provided with clamping grooves, the two clamping grooves are parallel to each other and the opening directions are opposite, a small clamping wheel and a large clamping wheel are installed between the two inner plates, the small clamping wheel and the large clamping wheel are located on the two sides of the clamping groove respectively, the inner plate is provided with a guide groove corresponding to the positions of the small clamping wheel and the large clamping wheel, the rotation shafts of the small clamping wheel and the large clamping wheel are located in the guide groove, the inner plate is provided with a spring, one end of the spring is connected with the small clamping wheel and the large clamping wheel, and an included angle exists between the guide groove and the clamping groove. When installing the aluminum foil roll, the roll shaft of the aluminum foil roll is put into the upward clamping groove (at this time, the guide groove is inclined downward), the roll shaft extrudes the small clamping wheel and the large clamping wheel, the small clamping wheel and the large clamping wheel are extruded into the guide groove, after the roll shaft passes the small clamping wheel and the large clamping wheel, the small clamping wheel and the large clamping wheel are reset under the support of the spring and are located obliquely above the roll shaft respectively and are tangent to the roll shaft, with the rotation of the feeding plate, the opening of the clamping groove in which the aluminum foil roll is installed faces downward (at this time, the guide groove is inclined upward), the small clamping wheel and the large clamping wheel are located below the roll shaft, the roll shaft generates an oblique downward force on the small clamping wheel and the large clamping wheel, the small clamping wheel and the large clamping wheel apply the force on the guide groove through the rotation shafts, since the guide groove is inclined upward at this time, the small clamping wheel and the large clamping wheel cannot move upward along the guide groove, but can only support the roll shaft at the bottom of the guide groove, thereby limiting the aluminum foil roll from sliding out of the clamping groove. Through the arrangement of the clamping groove, the guide groove and the small and large clamping wheels, the quick feeding and convenient installation of the aluminum foil roll are realized, the installation structure of the aluminum foil roll is simplified, the installation efficiency is improved, the number of parts required for installing and fixing the roll shaft is reduced, and the cost is saved.

[0007] The guide groove comprises a receiving groove and a clamping roller groove, an included angle exists between the receiving groove and the clamping groove, the clamping roller groove is parallel to the clamping groove, the receiving groove and the clamping roller groove are communicated, and an included angle exists between the center line of the spring and the center line of the receiving groove. The center line of the spring points to the center of the clamping roller groove. When the aluminum foil roll is installed, the roll shaft contacts the small clamping wheel and the large clamping wheel first, the small clamping wheel and the large clamping wheel are extruded downward, the small clamping wheel and the large clamping wheel move out of the clamping roller groove first, then the small clamping wheel and the large clamping wheel continue to move along the receiving groove and avoid the space for the movement of the roll shaft, after the roll shaft passes, the small clamping wheel and the large clamping wheel move under the support of the spring and are moved to the position of the clamping roller groove again. After the feeding plate rotates 180°, the roll shaft generates a force on the small clamping wheel and the large clamping wheel, at this time, the small clamping wheel and the large clamping wheel apply the force on the clamping roller groove through the rotation shafts, since the clamping roller groove is in a vertical state, the small clamping wheel and the large clamping wheel will not move into the receiving groove under the extrusion of the roll shaft, therefore, the small clamping wheel and the large clamping wheel can stably support the roll shaft. When it is needed to take out the empty roll shaft from the clamping groove, the roll shaft can be pulled out from one side of the feeding plate, or the small clamping wheel or the large clamping wheel can be pressed first and then the roll shaft is taken out of the clamping groove.

In the release process, the ratchet plate is extruded by the shaft sleeve, so that the ratchet plate rotates around the pin shaft and avoids the rotation space of the shaft sleeve. When the aluminum foil is released, the release motor is reversed, so that the ratchet plate enters the positioning groove again. When the pressure value detected by the pressure detector reaches the internal setting value of the control system, the release motor stops rotating, the avoiding cylinder pulls the release motor backward, so that the roller shaft and the shaft sleeve are separated. Then, the feeding plate rotates by 180 degrees, and the new aluminum foil roll rotates to the height of the release motor again. In this process, the avoiding cylinder pushes the release motor back to the original position again, so that the new roller shaft is clamped with the shaft sleeve.

[0052] An aluminum-plastic film production method with double-sided coating function comprises the following specific steps:

[0053] S1, releasing an aluminum foil 102;

[0054] S2, cleaning the surface of the aluminum foil 102 on both sides;

[0055] S3, coating the aluminum foil 102 on both sides;

[0056] S4, heating and drying the coated aluminum foil 102.

[0057] S5, winding the aluminum foil 102.

[0058] The step S2 comprises the following specific steps:

[0059] S201, the dust cloth 4014 is used to clean the surface of the aluminum foil 102;

[0060] S202, the dust cloth 4014 is used to heat the aluminum foil 102 while cleaning.

[0061] The working principle of the present application is as follows:

[0062] When the aluminum foil roll 1 is installed, the roll shaft 101 of the aluminum foil roll 1 is put into the upward clamping groove (at this time, the guide groove 307 is inclined downward), when the roll shaft 101 contacts the small clamping wheel 301 and the large clamping wheel 302, the small clamping wheel 301 and the large clamping wheel 302 are first pressed downward, and the small clamping wheel 301 and the large clamping wheel 302 are first moved out of the clamping roller groove 3072, then the small clamping wheel 301 and the large clamping wheel 302 continue to move along the storage groove 3071 to avoid the space for the movement of the roll shaft 101, and after the roll shaft 101 passes, the small clamping wheel 301 and the large clamping wheel 302 move under the support of the spring and move to the position of the clamping roller groove 3072 again.

[0063] The rotating hydraulic cylinder drives the feeding plate 3 to rotate 180°, after the feeding plate 3 rotates 180°, the roll shaft 101 generates a force on the small clamping wheel 301 and the large clamping wheel 302, at this time, the small clamping wheel 301 and the large clamping wheel 302 apply the force to the clamping roller groove 3072 through the rotating shaft, since the clamping roller groove 3072 is in a vertical state, the small clamping wheel 301 and the large clamping wheel 302 will not move into the storage groove 3071 under the extrusion of the roll shaft 101, therefore, the small clamping wheel 301 and the large clamping wheel 302 can stably support the roll shaft 101. When it is needed to take out the empty roll shaft 101 from the clamping groove, the roll shaft 101 can be pulled out from one side of the feeding plate 3, or the small clamping wheel 301 or the large clamping wheel 302 can be pressed first, and then the roll shaft 101 is taken out of the clamping groove.

[0064] After the feeding plate 3 rotates 180°, the triangular end of the roller shaft 101 is clamped with the shaft sleeve 204, and then the roller shaft 101 drives the aluminum foil roll 1 to rotate and release the aluminum foil 102 by releasing the rotation output of the release motor 202. During the release process, the ratchet plate 206 is pressed by the shaft sleeve 204, so that the ratchet plate 206 rotates around the pin shaft and avoids the rotation space of the shaft sleeve 204. When the release of the aluminum foil 102 is completed, the release motor 202 is reversed to make the ratchet plate 206 enter the positioning groove again. When the pressure value detected by the pressure detector reaches the internal setting value of the control system, the release motor 202 stops rotating, the avoidance cylinder pulls the release motor 202 backward to separate the roller shaft 101 from the shaft sleeve 204, and then the feeding plate 3 rotates 180°. The new aluminum foil roll 1 rotates to the height of the release motor 202 again. In this process, the avoidance cylinder pushes the release motor 202 back to the original position again, so that the new roller shaft 101 is clamped with the shaft sleeve 204.

[0065] The aluminum foil 102 enters the coating bin for coating, and then passes through the heating bin for drying, and finally flows out between the two discharge rollers 5 and is wound on the winding roller.

[0066] The dust brush 4014 is driven by the hot air roller 4015, and the driving motor drives the hot air roller 4015 to rotate. The hot air roller 4015 drives the dust brush 4014 to move through the friction force between the sawtooth groove and the protrusion. The dust brush 4014 moves on the outside of the aluminum foil 102 and cleans the dust on the surface of the aluminum foil. The movement direction of the dust brush 4014 is opposite to the movement direction of the aluminum foil 102, and the two dust brushes 4014 cooperate with each other to clean the surface of the aluminum foil 102.

[0067] In the process of movement of the dust brush 4014, the hot air roller 4015 injects hot air into the bottom shell 4011. The accumulated hot air passes through the dust brush 4014 and moves to the outside of the dust brush 4014. After the dust brush 4014 is heated by the hot air, the dust brush 4014 heats the aluminum foil 102 while removing the dust on the aluminum foil 102, which can accelerate the drying speed of the coating liquid on the surface of the aluminum foil 102.

[0068] The hot air heats the bottom shell 4011 and the dust brush 4014 wrapped by the dust brush 4014. The heat accelerates the separation of dust on the surface of the aluminum foil 102. At the same time, when the hot air passes through the dust brush 4014, the hot air washes the dust brush 4014 and the dust on the surface of the dust brush 4014. Part of the dust leaves the surface of the dust brush 4014, and the remaining dust is scraped by the scraper 4012 and enters the inside of the cover plate 4013. The dust removal system extracts the air inside the bottom shell 4011 through the dust removal pipe. The hot air carrying the dust in the air enters the dust removal pipe to clean the air inside the bottom shell 4011 and the dust scraped by the scraper 4012.

[0069] The hot roller 405 heats the air inside the heating bin, and through the trapezoidal arrangement, the heat dissipation area is increased. The bellows 403 transports the breeze between the two hot rollers 405 through the air port 404. The size of the air volume will not cause damage to the aluminum foil. The wind screen 407 divides and blocks the breeze. The breeze is heated by the hot roller 405 and blown on the surface of the coated aluminum foil 102, which accelerates the drying of the coating liquid on the surface of the aluminum foil 102, speeds up the drying speed, and improves the coating efficiency of the surface of the aluminum foil 102.
