The rubberizing device capable of automatically changing the roll comprises a feeding unit, the cutting unit and the rubberizing unit, the material loading unit includes two assemblies 500 that unreel, it is used for installing the material book of material area 900 to unreel the assembly 500, it is used for the alternative pay-off of material area 900 to unreel the assembly 500, the cutting unit is located the low reaches of material loading unit, the cutting unit is used for installing on the conveying route of material area 900, the cutting unit is used for cutting off material area 900 and the material area 900 after cutting off, two rubberizing units are located the both sides of cutting the unit respectively, the rubberizing unit includes the subassembly 100 that prepares with glue and the rubberizing subassembly 200, the subassembly 100 that prepares with glue is used for providing the sticky tape, the rubberizing subassembly 200 includes rubberizing executor 210, rubberizing executor 210 is used for following the subassembly 100 that prepares with glue and moves to material area 900 in order to paste the sticky tape, the route of rubberizing executor 210 is perpendicular to the conveying route of material area 900, the cutting unit can move in order to dodge rubberizing executor 210.

It will be appreciated that since the cutting unit needs to feed in a direction perpendicular to the strip of material 900 to cut the strip of material 900, the path of movement of the taping actuator 210 when taping interferes with the path of movement of the cutting unit when cutting, and the cutting unit blocks the path of movement of the taping actuator 210. In some existing technologies, the cutting unit does not have an avoiding capability, so when the tape is applied, the tape application actuator 210 first needs to wait at a first preparation position that does not correspond to the cutting position of the tape 900, and after the cutting unit retracts to avoid, the cutting unit reaches a second preparation position that corresponds to the cutting position from the first preparation position, and finally, the cutting unit performs linear motion to complete the tape application. This results in at least two movements of the gluing actuator 210 to complete the gluing, which makes the driving structure of the gluing actuator 210 complicated.

According to the rubberizing device capable of automatically changing the roll, when the tape is cut off, the cutting unit cuts the tape 900 and then separates the tape 900 from the cutting position, when the roll is changed, the cutting unit firstly cuts the current tape 900, then one tape 900 connected with the original unreeling assembly 500 is abandoned, meanwhile, the tail end of the other tape 900 is positioned, the other unreeling assembly 500 sends the head end of the new tape 900 to the cutting unit, the head end of the new tape 900 is in butt joint with the tail end of the original tape 900, and the rubberizing actuator 210 makes a linear motion perpendicular to the tape 900 to attach the tape at the cutting position, so that the two sections of tape 900 which are originally disconnected are connected together again.

Because the cutting unit can avoid, the movement of the rubberizing executor 210 from the glue preparation assembly 100 to the material belt 900 is a linear movement, so that the rubberizing executor 210 can complete rubberizing only by performing a section of movement, and the rubberizing device capable of automatically changing rolls can simplify the feeding process of the adhesive tape and is beneficial to simplifying the driving structure of the rubberizing device capable of automatically changing rolls. Meanwhile, the avoiding action of the cutting unit and the rubberizing action of the rubberizing actuator 210 can be performed in parallel, and the efficiency of the rubberizing device capable of automatically changing rolls is improved. The efficiency of the rubberizing device capable of automatically changing the roll can be improved by arranging the two unwinding assemblies 500 to alternately feed materials.

The taping actuator 210 may take tape by negative pressure suction.

Avoidance of the cutting unit can be accomplished in a variety of ways, so long as the cutting unit does not interfere with the path of movement of the taping actuator 210. In some embodiments, the cutting unit is movable along the transport path of the strip 900 to clear the taping actuator 210. In other implementations, the cutting unit may also be retracted to clear the taping actuator 210.

When the tape 900 is cut, the tape 900 is first clamped and positioned by the clamping assembly 400, and then the tape 900 is cut by the cutter assembly 300. The two clamp assemblies 400 are moved away from each other after cutting to separate the cut strip 900 while the cutter assembly 300 is moved to clear the taping actuator 210.

The movement of the cutting unit along the transport path of the strip 900 may be achieved in different ways as long as the position of the cutter assembly 300 is offset from the cutting position of the strip 900 by a certain distance. For example, the cutter assembly 300 may be configured to move so that the cut position of the strip of material 900 is offset from the cutter assembly 300. Or the two clamping assemblies 400 can drive the material belt 900 to move, so that the cutting position of the material belt 900 is staggered with the position of the cutter assembly 300, and the interference between the rubberizing actuator 210 and the cutter assembly 300 is avoided. It is also possible that both the cutter assembly 300 and the clamp assembly 400 can be moved out of the way.

The material belt 900 of the unreeling assembly 500 to be unreeled is connected to the corresponding reel changing mechanism, and when the material roll in the unreeling assembly 500 to be unreeled is used up, the reel changing mechanism of the unreeling assembly 500 to be unreeled moves to the cutting unit, so that a new material belt 900 is sent to the cutting unit to be reeled.

It will be appreciated that, according to the principle of defining a straight line at two points, the first reel change actuator 520 and the second reel change actuator 530 are capable of fully defining the position of the length of the strip of material 900 therebetween such that the position of the length of the strip of material 900 coincides with the feed line of the strip of material 900 and such that the length of the strip of material 900 can be gripped by the gripping assembly 400 upstream of the cutter assembly 300 and severed by the cutter assembly 300.

Specifically, the roll change process may be performed as follows:

when the first reel change actuator 520 and the second reel change actuator 530 carry the material strip 900 to be changed, the cutter assembly 300 and the clamping assembly 400 positioned upstream of the cutter assembly 300 retract to avoid, and the original material strip 900 is clamped on the clamping assembly 400 positioned downstream of the cutter assembly 300;

For example, the first reel change actuator 520 and the second reel change actuator 530 may respectively clamp the material tape 900 from two places, so as to drive the material tape 900 to move, thereby achieving the position adjustment of the material tape 900. Alternatively, the first reel-change actuator 520 may grip the head of the strip of material 900 and the second reel-change actuator 530 may push the strip of material 900 at another location, which also allows the position of the strip of material 900 to be adjusted.
