Description

Technical Field

[0001] This utility model relates to the field of web guiding devices, specifically a web guiding device for unwinding in the production of aluminized film. Background Technology

[0002] Metallized film is produced by vacuum metallization, in which high-purity aluminum wire is evaporated into a gaseous state at high temperature. When the plastic film passes through the vacuum evaporation chamber, the gaseous aluminum molecules precipitate onto the surface of the plastic film, forming a bright metallic film. In the production process of metallized film, the unwinding and correction device is one of the key pieces of equipment to ensure accurate material delivery. Currently, this device mainly uses a correction sensor head to sense the unwinding status of the metallized film. The correction cylinder pushes the unwinding frame to move in a specific direction, thereby correcting the material deviation during the unwinding process. The bottom of the unwinding frame is usually equipped with sliders, which slide in conjunction with the slide rails on the base of the unwinding frame to ensure that the unwinding frame can move smoothly and accurately.

[0003] Currently, most unwinding and correction devices on the market adopt the above structure, that is, the sliding cooperation between the slider and the slide rail realizes the correction function of the unwinding frame. However, in the existing correction devices, the slide rail is usually in a completely exposed state. During the production process, dust, debris and other impurities in the workshop are easy to accumulate on the slide rail. These impurities not only increase the friction between the slider and the slide rail, but may also cause the slider to slide poorly or even get stuck, which will have a certain impact on the correction process. Therefore, in view of the above situation, an unwinding and correction device for aluminum-coated film production is proposed. Utility Model Content

[0004] To address the problem that impurities in existing technologies tend to accumulate on the guide rails, thus affecting the correction process, this invention proposes an unwinding and correction device for aluminum-coated film production.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an unwinding and correction device for aluminum-coated film production, including a base and a protective component. The base is provided with slide rails, and there are four slide rails. The four slide rails are distributed in a rectangular shape on the base, and each of the four slide rails has a sliding part that is slidably engaged.

[0006] Each of the four sliding parts is fixedly connected to a support block at its top, and a fixing plate is fixedly connected to both sides of each support block. The fixing plate has screw holes.

[0007] The length of the protective component is greater than the length of the slide rail. The protective component includes a first protective housing and a second protective housing. A clamping plate is fixedly connected to one side of the first protective housing. There are two clamping plates. A connecting plate is fixedly connected to the side of the second protective housing close to the first protective housing. There are two connecting plates. The two connecting plates have connecting grooves.

[0008] The top of both the first and second protective housings has positioning holes, and there are notches between the two card plates and the two connecting plates.

[0009] When the card plate is snapped into the connecting groove, the notch abuts against the surface of the support block, the tops of the first protective shell and the second protective shell respectively contact the bottom of the fixing plate, and a bolt is threaded into the screw hole. After the bolt passes through the screw hole, it engages with the positioning hole.

[0010] Preferably, a roll unwinding frame is fixedly connected to the four support blocks.

[0011] Preferably, the unwinding frame includes two support plates, each fixedly connected to a support block. A transverse reinforcing rod is fixedly connected to each support plate, and an unwinding roller is also provided on each support plate.

[0012] Preferably, the base is provided with a correction cylinder, and the moving end of the correction cylinder is fixedly connected to one of the support plates.

[0013] Preferably, the base is also provided with a bracket, and the bracket is provided with a correction sensing head.

[0014] Preferably, both the first protective housing and the second protective housing have cavities that cooperate with the slide rail.

[0015] Preferably, the card plate is convex in shape.

[0016] Preferably, when the first protective shell and the second protective shell are fixed on the support block, there is a gap between the bottom of the first protective shell and the second protective shell and the base.

[0017] The advantages of this utility model are:

[0018] 1. Through the structural design of the first protective shell, the second protective shell, the positioning hole and the clamping plate, this utility model ensures that the slide rail is always covered during the sliding process of the sliding part, effectively preventing impurities from entering the slide rail, thereby avoiding the interference of impurities on the sliding performance of the sliding part, improving the moving accuracy of the unwinding frame, and thus ensuring that the correction device can accurately and stably realize the correction function, thereby improving the quality of aluminized film production.

[0019] 2. The structural design of this utility model, including a fixing plate, bolts, positioning holes, a clamping plate, and a connecting plate, makes the protective components easy to disassemble. This allows users to easily maintain the slide rail without disassembling the entire unwinding and correction device, simplifying the maintenance process and improving its efficiency and convenience.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0028] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0029] This application discloses an unwinding and web-correcting device for the production of aluminized film. (Refer to...) Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A winding and correction device for producing aluminized film includes a base 1 and a protective component 6. The base 1 is provided with four slide rails 2, which are arranged in a rectangular shape on the base 1. Each of the four slide rails 2 has a sliding part 201 that is slidably engaged with it. The sliding part 201 is any one of a slider or a pulley that engages with the slide rail 2.

[0030] Each of the four sliding parts 201 has a support block 202 fixedly connected to its top, and a fixing plate 4 fixedly connected to both sides of the support block 202. The fixing plate 4 has screw holes 401.

[0031] Among them, four support blocks 202 are fixedly connected to unwinding frames 3. Unwinding frames 3 include support plates. There are two support plates. The two support plates are fixedly connected to the support blocks 202 respectively. Horizontal reinforcing rods are fixedly connected to the two support plates. Unwinding rollers are also provided on the two support plates. Unwinding rollers are used to realize the unwinding operation during the processing of aluminum-coated film.

[0032] Correspondingly, the support block 202 can move the unwinding frame 3 left and right as the sliding part 201 moves left and right, thereby realizing the correction operation.

[0033] The length of the protective component 6 is greater than the length of the slide rail 2. The protective component 6 includes a first protective housing 601 and a second protective housing 602. A clamping plate 604 is fixedly connected to one side of the first protective housing 601. The clamping plate 604 is convex in shape and there are two clamping plates 604. A connecting plate 605 is fixedly connected to the side of the second protective housing 602 near the first protective housing 601. There are two connecting plates 605, and the two connecting plates 605 have connecting grooves 6050.

[0034] The top of both the first protective housing 601 and the second protective housing 602 has a positioning hole 603, which is preferably a screw hole. There is a notch 606 between the two clamping plates 604 and the two connecting plates 605.

[0035] When the card plate 604 is snapped into the connecting groove 6050, the notch 606 abuts against the surface of the support block 202. The tops of the first protective shell 601 and the second protective shell 602 respectively contact the bottom of the fixing plate 4. A bolt 5 is threaded into the screw hole 401. After the bolt 5 passes through the screw hole 401, it engages with the positioning hole 603.

[0036] Reference Figure 1 The base 1 is equipped with a correction cylinder 7, the moving end of the correction cylinder 7 is fixedly connected to one of the support plates, and the base 1 is also equipped with a bracket 8, on which a correction sensing head 9 is installed.

[0037] Among them, the correction cylinder 7 serves as the actuator for the correction operation, and the correction sensing head 9 can be any one of the following: a line-tracking sensor, a photoelectric sensor, or an ultrasonic sensor.

[0038] Correspondingly, both the correction cylinder 7 and the correction sensor head 9 are connected to an external correction controller.

[0039] Reference Figure 4 and Figure 5 Both the first protective housing 601 and the second protective housing 602 have cavities 607, which cooperate with the slide rail 2.

[0040] The first protective housing 601 and the second protective housing 602 completely cover the slide rail 2 through the cavity 607. When the first protective housing 601 and the second protective housing 602 slide left and right with the support block 202, the slide rail 2 is always inside the cavity 607 and will not collide.

[0041] Reference Figure 3 , Figure 4 and Figure 5 When the first protective housing 601 and the second protective housing 602 are fixed on the support block 202, there is a gap between the bottom of the first protective housing 601 and the second protective housing 602 and the base 1.

[0042] The presence of a certain gap ensures the protection of the slide rail 2 while preventing friction between the first protective housing 601 and the second protective housing 602 and the base 1, thereby improving the smoothness of the correction operation.

[0043] Working principle: In use, the first protective housing 601 and the second protective housing 602 are respectively gripped and inserted from the left and right sides of the slide rail 2, so that the top of the first protective housing 601 and the second protective housing 602 are in contact with the bottom surface of the fixing plate 4, and then the notch 606 is made to fit against the surface of the support block 202. At this time, the clamping plate 604 is completely inserted into the connecting groove 6050. Then, the operator inserts the bolt 5 into the screw hole 401 and tightens the bolt 5 so that it passes into the positioning hole 603 and engages with the thread of the positioning hole 603 to complete the positioning process of the first protective housing 601 and the second protective housing 602. At this time, the first protective housing 601 and the second protective housing 602 completely cover the slide rail 2.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
