Description

Technical Field

[0001] The present application relates to the technical field of aluminum-plastic film coating equipment, and in particular to a winding machine for UPS power supply processing. Background Art

[0002] An uninterruptible power supply (UPS) is a type of power supply that provides uninterrupted power to equipment. When the mains power is interrupted, it can maintain normal operation of the equipment and protect the equipment's load software and hardware from damage. Aluminum-plastic film, as an important material for battery packaging, plays a vital role in the production and processing of UPS power supplies.

[0003] Laminating aluminum foil with plastic film is an important process in the production and preparation of aluminum-plastic film, which mainly includes coating, drying, laminating and winding steps. Coating is to evenly apply the adhesive on the aluminum foil, and according to the use requirements of the aluminum foil film, the gap between the pressing roller and the coating roller is adjusted to control the coating thickness of the adhesive on the aluminum foil.

[0004] However, in the existing coating process, it is difficult to adjust the gap between the pressure glue roller and the coating roller and the accuracy is poor. In the process of adjusting the gap, it is very easy for the pressure glue roller to tilt, resulting in the gap between it and the coating roller being larger at one end and smaller at the other end, which greatly affects the uniformity of the adhesive coating on the aluminum foil. At the same time, the gap adjustment mechanism in the existing coating roller is complex in structure, resulting in a high failure rate during operation, and high production and daily maintenance costs, which invisibly increases the cost of aluminum foil film production.

[0005] After the aluminum-plastic film is prepared and formed, during the winding process, as the winding diameter of the aluminum-plastic film increases, the linear speed of the winding will increase accordingly when its angular velocity remains unchanged, which can easily cause excessive pulling on it and seriously affect the previous coating process, reducing the production and processing quality of the aluminum-plastic film, and having poor stability and reliability.

[0006] Therefore, there is an urgent need for a production and processing component for the aluminum foil film on the UPS to solve the defects of the above-mentioned existing aluminum-plastic film in the actual production and processing process. Summary of the Invention

[0007] The present application proposes a winding machine for UPS power supply processing, which has the advantages of low difficulty and high precision in adjusting the gap between the pressing roller and the coating roller, so that the gap between them will not be larger at one end and smaller at the other end, high uniformity in adhesive coating on the aluminum foil, and automatic adjustment of the linear speed of the aluminum-plastic film winding according to changes in the aluminum-plastic film winding weight, so as to achieve high processing quality of the aluminum-plastic film. It is used to solve the problems of high difficulty and poor precision in adjusting the gap between the pressing roller and the coating roller in the existing coating process, and the problem that the gap between the pressing roller and the coating roller is easily larger at one end and smaller at the other end due to the tilt of the pressing roller during the gap adjustment process, and that during the winding process of the aluminum-plastic film after it is prepared and formed, as the winding diameter of the aluminum-plastic film increases, the linear speed of the winding will increase accordingly when its angular velocity remains unchanged, which is very likely to cause excessive pulling of the film.

[0008] To achieve the above objectives, the present application adopts the following technical solution: a winding machine for UPS power supply processing, comprising a bracket, a drive shaft fixedly mounted on the interior of the right side of the bracket, the outer surface of the drive shaft being provided with three groups of conductive blocks arranged in a circular array, an inner sleeve fixedly mounted on the outer surface of the drive shaft, and three groups of coils forming conductive contact with the conductive blocks being disposed within the inner sleeve, a group of disc springs movably mounted on both sides of the outer surface of the inner sleeve, a coating roller movably mounted on the outer periphery of the inner sleeve via the disc springs, and a gap being formed between the inner wall of the coating roller and the outer surface of the inner sleeve, and a magnetic strip fixedly mounted on the inner wall of the coating roller;

[0009] Grooved rails are respectively provided at both ends of the left side of the bracket, and a winding roller is provided between the two sets of groove rails. The end of the winding roller is transmission-connected to the bottom end of the groove rail through an elastic member fixedly installed inside the groove rail, and an end cover is provided at the top end of the groove rail. A transmission disk is fixedly installed at one end of the outer surface of the winding roller, and the winding roller is transmission-connected to a power machine fixedly installed with a main shaft arranged on the center of the groove rail through the transmission disk.

[0010] Furthermore, a piezoelectric module is provided inside the groove rail, and the piezoelectric module forms a negative feedback connection with the power machine through a control system.

[0011] Furthermore, the plurality of groups of magnetic strips and magnetic poles fixedly mounted on the inner wall of the coating roller are arranged in an alternating manner.

[0012] Furthermore, the three groups of coils on the inner sleeve are arranged in a circular array, wherein one group is located at the bottom of the inner sleeve, and the other two groups of coils are symmetrically distributed on the left and right sides of the top of the inner sleeve.

[0013] Further, a set of third grooves are respectively formed on both sides of the outer surface of the coating roller, and a scraping ring with a semi - circular structure is movably sleeved around the coating roller through the third grooves. The right side of the outer surface of the scraping ring is clamped with a guide rod fixedly installed on the bracket.

[0014] Further, a set of first grooves are respectively formed on both sides of the outer surface of the inner bushing and are clamped with the inner wall of the disc - shaped spring, and second grooves for clamping with the outer surface of the disc - shaped spring are formed on the inner wall of the coating roller.

[0015] Further, when the central axis of the coating roller is in the initial state, under the elastic force of the disc - shaped spring, it coincides with the central axis of the transmission shaft, and the minimum magnetic field combined force generated by the three groups of coils when energized is greater than the elastic force of the disc - shaped spring.

[0016] Further, the top of the outer surface of the coating roller is located above the top of the scraping ring, thus effectively avoiding the interference between the aluminum foil conveyed on the coating mechanism and the scraping ring and the problem of scratching the surface of the aluminum foil. At the same time, it ensures that the aluminum foil makes full extrusion contact with the adhesive carried on the outer surface of the coating roller.

[0017] The present invention application has the following technical effects:

[0018] 1. For the winding machine for UPS power supply processing provided in this application, regarding the setting of the transmission shaft and the inner bushing, by changing the magnetic field intensity generated between the three groups of coils on the inner bushing, under the action of the magnetic strip, the coating roller is forced to shift upward against the elastic force of the disc - shaped spring, thereby adjusting the gap between the outer surface of the coating roller and the pressure - sensitive adhesive roller, so that the gap will not be large at one end and small at the other end. The uniformity of the adhesive coating on the aluminum foil is relatively high, and the existing gap adjustment mechanism inside the coating roller is greatly optimized, with a lower failure rate during operation, and lower preparation and daily maintenance costs.

[0019] 2. For the winding machine for UPS power supply processing provided in this application, regarding the setting of the winding roller and its structure, according to the weight of the winding roller during the process of winding the aluminum - plastic film and the change in the diameter of the wound aluminum - plastic film, the winding linear speed of the aluminum - plastic film on it can be automatically adjusted to maintain a relatively stable winding tension of the winding roller on the aluminum - plastic film, without causing excessive pulling phenomenon, thereby effectively improving the processing quality of the aluminum - plastic film by this winding machine.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0029] As Figure 1 shown, a winding machine for processing a UPS power supply includes a bracket 1 fixedly installed in a storage adhesive chamber. Inside the right side of the bracket 1, a transmission shaft 2 is fixedly installed. As Figure 2 shown, on the outer surface of the transmission shaft 2, three groups of conductive blocks 8 arranged in a circular array are provided, and the three groups of conductive blocks 8 are respectively independently electrically connected to an external power supply. On the outer surface of the transmission shaft 2, an inner shaft sleeve 3 is fixedly sleeved, and inside the inner shaft sleeve 3, three groups of coils 9 that form electrical contact with the conductive blocks 8 are provided. On both sides of the outer surface of the inner shaft sleeve 3, a group of disc springs 4 with a constant pressure structure are respectively movably sleeved, and through the disc springs 4, a coating roller 5 is movably sleeved on the periphery of the inner shaft sleeve 3. A gap for accommodating the up and down displacement of the coating roller 5 is formed between the inner wall of the coating roller 5 and the outer surface of the inner shaft sleeve 3. As Figure 3 shown, a magnetic strip 11 is fixedly installed on the inner wall of the coating roller 5. Thus, by changing the magnetic field intensity generated between the three groups of coils 9 on the inner shaft sleeve 3, under the action of the magnetic strip 11, the coating roller 5 is forced to move upward against the elastic force of the disc spring 4, and the gap between the outer surface of the coating roller 5 and the pressure rubber roller is adjusted;

[0030] On both ends of the left side of the bracket 1, a set of arc-shaped slot tracks 14 are respectively provided, and a winding roller 15 is arranged between the two sets of slot tracks 14. The end of the winding roller 15 is in transmission connection with the bottom end of the slot track 14 through an elastic member 16 fixedly installed inside the slot track 14. Thus, when more and more aluminum-plastic film is wound on the winding roller 15, as its mass increases, the winding roller 15 moves downward along the track of the slot track 14 by overcoming the elastic force of the elastic member 16. And a end cover 17 for limiting the maximum upward displacement of the winding roller 15 is provided at the top end of the slot track 14. A transmission disk 18 is fixedly installed at one end of the outer surface of the winding roller 15, and the winding roller 15 is in transmission connection with a power machine fixedly installed on the main shaft at the center of the circle of the slot track 14 through the transmission disk 18. Thus, when the power machine is started, the winding roller 15 is driven to rotate accordingly, and the aluminum-plastic film extruded and formed on the coating roller 5 is wound.

[0031] In this technical solution, a piezoelectric module is provided inside the slot track 14, and the piezoelectric module is in negative feedback connection with the power machine through a control system. Thus, when the piezoelectric module on it is triggered due to the increase in the mass of the winding roller 15, the rotation speed of the power machine can be reduced to reduce the angular velocity of the winding roller 15, and according to the change in the winding diameter of the aluminum-plastic film by the winding roller 15, its linear velocity does not change, so as to maintain a relatively stable winding tension of the winding roller 15 on the aluminum-plastic film.

[0032] In this technical solution, several groups of magnetic strips 11 fixedly installed on the inner wall of the coating roller 5 are arranged with their magnetic poles staggered in sequence. And in the case of like magnetic poles repelling and unlike magnetic poles attracting, when the three groups of coils 9 generate magnetic fields with opposite magnetic poles at the positions corresponding to the magnetic strips 11 on the coating roller 5, while the coating roller 5 deflects, it can be forced to rotate, and thus the adhesive stored in the chamber is carried along the outer wall of the coating roller 5 to its top and coated on the aluminum foil.

[0033] As Figure 5 shown, in this technical solution, the three groups of coils 9 on the inner shaft sleeve 3 are arranged in a circular array. Among them, one group is located at the bottommost end of the inner shaft sleeve 3, and the other two groups of coils 9 are symmetrically distributed on the left and right sides at the top of the inner shaft sleeve 3. Thus, when the three groups of coils 9 are respectively energized, the resultant magnetic force applied to the coating roller 5 by them is along the vertical direction, forcing the coating roller 5 to deflect upward or downward, and thus effectively improving the stability of the coating roller 5 during rotation.

[0034] As Figure 3 、 Figure 5As shown, in this technical solution, a set of third grooves 13 are respectively formed on both sides of the outer surface of the coating roller 5, and a scraping ring 7 with a semi-ring structure is movably sleeved around the coating roller 5 through the third grooves 13, so as to scrape flat the adhesive rotated and carried on the outer surface of the coating roller 5 and control the conveying amount of the adhesive rotated and carried on its outer surface. The right side of the outer surface of the scraping ring 7 is clamped with the guide rod 6 fixedly installed on the bracket 1, and under the action of the third grooves 13, when the coating roller 5 moves up and down, the scraping ring 7 can be driven to move up and down accordingly, so as to ensure that the gap between the inner wall of the scraping ring 7 and the outer surface of the coating roller 5 remains unchanged.

[0035] As Figure 2 , Figure 3 and Figure 4 As shown, in this technical solution, a set of first grooves 10 are respectively formed on both sides of the outer surface of the inner shaft sleeve 3 and are clamped with the inner wall of the disc spring 4, and a second groove 12 for clamping with the outer surface of the disc spring 4 is formed on the inner wall of the coating roller 5, so as to effectively limit the axial movement of the coating roller 5, making it not prone to axial offset during the rotation and offset process, and effectively avoiding the phenomenon that the whole aluminum foil extruded and conveyed in this coating process is offset.

[0036] As Figure 5 As shown, in this technical solution, when the central axis of the coating roller 5 is in the initial state, it coincides with the central axis of the transmission shaft 2 under the elastic force of the disc spring 4, and the minimum magnetic field combined force generated by the three coils 9 when energized on the coating roller 5 is greater than the elastic force of the disc spring 4. Therefore, when the three coils 9 are respectively energized, the coating roller 5 can be effectively forced to move accordingly.

[0037] As Figure 5 As shown, in this technical solution, the top of the outer surface of the coating roller 5 is located above the top of the scraping ring 7, so as to effectively avoid the interference between the aluminum foil conveyed on the coating mechanism and the scraping ring 7 and the problem of scratching damage to the surface of the aluminum foil. At the same time, it ensures that the aluminum foil can fully make extrusion contact with the adhesive carried on the outer surface of the coating roller 5.
