In order to make the objects, technical solutions and advantages of the present utility model more apparent, the present utility model will be described in detail with reference to the accompanying drawings and examples. It should be understood that the following specific examples are given by way of illustration only and are not intended to be limiting.

As shown in fig. 1 to 2, in order to achieve the above object, the present utility model provides a tab embossing roll quick switching device, comprising:

And at least two press roller assemblies with different embossing shapes are used for embossing the tabs, and the two press roller assemblies are connected to the moving block 14 and can move along with the moving block 14 so as to realize the switching of the press roller assemblies.

Specifically, the fixing plate 11 is made of a metal material, such as an aluminum alloy material, an alloy steel material, etc., and the fixing plate 11 made of a metal material has the advantages of strong supporting capability, wear resistance, etc. The fixed plate 11 is vertically placed, a sliding rail is arranged on the fixed plate 11, two ends of the sliding rail are respectively and fixedly connected to the fixed plate 11, and the sliding rail is used for supporting the reciprocating motion of the moving block 14. The moving block 14 is a movable member connected to the platen roller assembly. The guide on the sliding rail can be used for carrying out back-and-forth reciprocating motion along the length direction of the sliding rail. The main function of the moving block 14 is to support the movement of the press roll assembly and to achieve a rapid switching of the press roll assembly of different embossing shapes. It is conceivable that the movement of the driving movement block 14 may be achieved by a telescopic cylinder, or may be achieved by a screw, and a locking structure.

The application is preferably realized by a screw rod, and is exemplified as follows:

The lead screw is located one side of slide rail, and the lead screw runs through movable block 14, threaded connection between movable block 14 and the lead screw, and the one end of lead screw passes through first servo motor 12 drive, and the lead screw rotates under the drive of first servo motor 12 this moment to realize that movable block 14 moves along the length direction of slide rail. A coupling 13 is further provided between the screw and the first servo motor 12, and power and torque are transmitted through the coupling 13, so that rotation between shafts can effectively transmit power.

When the locking assembly is adopted, the moving block 14 can be manually driven to move, and after the moving block 14 moves to a designated position, the moving block 14 is locked on the sliding rail through the locking device, so that the position adjustment is completed.

The press roll assembly is a component for embossing the tab. In the present application, there are at least two press roll assemblies, and they have different embossing shapes. Taking two press roller assemblies as examples, namely a first press roller assembly and a second press roller assembly, wherein the first press roller assembly can press a stripe shape, and the second press roller assembly can press a dot shape; the first compression roller assembly and the second compression roller assembly are fixedly connected to the moving block 14 and can move along with the moving block 14. By moving the moving block 14, the correspondence between different press roller assemblies and the lugs can be realized, so that the embossing treatment of different shapes on the lugs can be realized.

With the above technical solution, the press roll assemblies of different embossing shapes can be rapidly switched by the reciprocating movement of the moving block 14. Different embossing shapes can be flexibly selected in the processing process so as to meet different requirements. Meanwhile, since the pressing roller assembly is tightly connected with the moving block 14 and accurately moves through the sliding rail, accurate embossing treatment of the tab can be realized. This accuracy helps to improve process quality and consistency.

In one embodiment of the present application, the press roll assembly includes:

A press roller cylinder 21, the fixed part of which is connected to the moving block 14;

A support member 22 connected to the telescopic shaft of the pressure roller cylinder 21; and

The press roller 23 is rotatably connected to the supporting member 22, and the supporting member 22 can drive the press roller 23 to press or be far away from the outer surface of the tab.

Specifically, the pressing roller cylinder 21 is a main driving device of the pressing roller assembly, and a telescopic cylinder commonly used in the prior art can be adopted, and a fixed part of the pressing roller cylinder 21 is connected to the moving block 14. The compression roller cylinder 21 is connected with the movable block 14 in a fixed connection mode, the connection strength between the compression roller cylinder 21 and the movable block 14 can be improved, and the stability of the compression roller cylinder 21 during operation is guaranteed. Of course, according to the design requirement, the compression roller cylinder 21 and the moving block 14 can be connected in a detachable manner, such as screw connection, bolt connection, and the like, and the compression roller cylinder 21 and the moving block 14 can be conveniently installed and detached, so that later maintenance is facilitated. The press roller cylinder 21 is used for pressing the press roller 23 on the tab so as to realize embossing treatment on the tab.

The supporting member 22 is connected to a telescopic shaft of the platen roller cylinder 21 for supporting and positioning the platen roller 23. The main function of the support 22 is to provide a stable support platform, enabling the pressure roller 23 to effectively apply pressure to the outer surface of the tab.

Specifically, the first servomotor 12 is a control motor, and is mounted on the fixed plate 11. The first servo motor 12 drives the reciprocating motion of the moving block 14 by driving the rotation of the first screw rod. The first servo motor 12 can precisely control the rotation angle and speed according to the control signal, so as to realize precise control on the motion of the moving block 14.

The first screw is a rod-shaped member of a spiral shape, and is fixed to the fixing plate 11. The sliding rail is in threaded connection with the moving block 14, and the moving block 14 is driven to reciprocate along the length direction of the sliding rail through rotation. When the first servo motor 12 rotates, power and motion are transmitted through threads, so that the moving block 14 can perform stable reciprocating motion on the sliding rail.

The first servomotor 12 is mounted on the fixed plate 11 and is connected to the first screw through a transmission (e.g., a coupling 13 or a gear). The threads of the first screw are engaged with the threaded holes of the moving block 14 so that they are screwed together. The moving block 14 is slidably connected to the sliding rail, and can slide smoothly along the length direction of the sliding rail by driving the screw rod.

By adopting the technical scheme, the first servo motor 12 realizes accurate control of the position of the movable block 14 by controlling the rotation of the first screw rod. This enables the system to achieve high precision reciprocating motion, meeting precise control of position. Since the moving block 14 is connected to the first screw rod by screw threads and slides on the slide rail, smooth reciprocating motion can be achieved. This helps reduce vibration and shock, providing more reliable athletic performance.

In one embodiment of the present application, a traversing assembly is further included, and the traversing assembly may be used to drive the fixed plate 11 to reciprocate along the width direction of the pole piece.

The traversing assembly is mounted to the bottom of the fixed plate 11 and is coupled to the fixed plate 11 by a transmission (e.g., belt, gear, etc.). The motor transmits power to the fixing plate 11 through the transmission device so that the fixing plate reciprocates along the width direction of the pole piece. Thereby facilitating the press roller 23 to correspond to different positions on the pole piece.

With the above technical solution, the lateral movement of the fixing plate 11 can expand the working space of the system. By adjusting the driving of the traversing assembly, the fixing plate 11 can be made to cover a larger range in the width direction, providing a larger operation area.
