Description

Technical Field

[0001] This invention relates to the field of polyester Mylar tape technology, and in particular to a polyester Mylar tape production equipment and its production process. Background Technology

[0002] Mylar tape, also known as Mylar tape, transformer tape, or silicone Mylar tape, is a single-sided adhesive tape. Mylar tape is widely used for insulation wrapping of various motors and electronic components such as transformers, motors, and capacitors, as well as for high-voltage isolation between the main circuit board and the casing of switching power supplies. It is also used for wrapping soft-pack lithium batteries; for example, when wrapped between the protection board and the battery cell, it serves to fix, insulate, and prevent fire.

[0003] Polyester Mylar tape: It is made by mixing 35%~45% solid content acrylic adhesive with 15%~25% halogen-free flame retardant powder, 1%~5% color powder (light yellow, dark yellow, red, blue, green, white and black need to be ground into color paste), 0~10% titanium dioxide (added as needed after grinding into color paste), and 0.1%~1% curing agent. After stirring evenly and filtering, it is evenly coated onto polyester film on a coating production line to make polyester Mylar tape.

[0004] Manufacturers typically produce a type of tape with a width of 1 meter or more, which is then cut to size as needed.

[0005] In the production process, it is usually necessary to wind up polyester Mylar tape. Traditionally, one end of the polyester Mylar tape is glued to the winding drum using adhesive tape, and the tape is wound around the drum by rotating it. However, this not only consumes a large amount of adhesive tape, but also requires additional manual labor, resulting in a waste of manpower and resources.

[0006] Therefore, how to design a polyester Mylar tape production equipment and its production process that can automatically clamp and wind the polyester Mylar tape without using adhesive paper is a technical problem that needs to be solved. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a polyester Mylar tape production equipment and its production process, which automatically clamps and winds the polyester Mylar tape without the need for adhesive tape.

The rotating part is bent and clamped on the fixed shaft. The elastic part and the pressure part are respectively located at both ends of the rotating part.

[0015] The take-up and unwinding spool also includes a rotating blocking shaft and a resetting blocking shaft housed inside the spool body. The rotating blocking shaft is used to block the elastic part, and the resetting blocking shaft is used to block the pressing part.

[0016] The drum body has a feed inlet on its wall, and the inside of the drum body has a pressing surface at the feed inlet. The pressing part contacts or separates from the pressing surface.

[0017] In one embodiment, the driving device includes: a telescopic driving mechanism and a rotation driving mechanism;

[0018] The rotation drive mechanism is provided with a main drive rod, and the end of the drum body is provided with a main arc-shaped through hole corresponding to the main drive rod;

[0019] The telescopic drive mechanism drives the rotary drive mechanism to extend and retract, so that the main drive rod enters or exits the interior of the drum body through the main arc-shaped through hole;

[0020] The rotation drive mechanism drives the main drive rod to rotate, so that the main drive rod drives the movable pressure plate to rotate, thereby driving the drum body to rotate.

[0021] In one embodiment, the rotation drive mechanism is provided with a secondary drive rod, and the end of the drum body is provided with a secondary arc-shaped through hole corresponding to the secondary drive rod.

[0024] In one embodiment, the rotating part and the fixed shaft are clearance-fitted.

[0025] In one embodiment, the rotating part and the fixed shaft are in frictional engagement.

[0026] A process for producing polyester Mylar tape involves using the aforementioned polyester Mylar tape production equipment to wind the polyester Mylar tape into the take-up and unwinding roll.

[0044] Please refer to the following: Figure 1 , Figure 2 and Figure 3 The present invention discloses a polyester Mylar tape production equipment 10, including a base 20 and a take-up and untake-up roll body 30 rotatably disposed on the base 20.

[0045] like Figure 3As shown, the polyester Mylar tape production equipment 10 also includes a drive device 40, which is drivenly connected to the take-up and untake-down roll body 30. The drive device 40 is used to drive the take-up and untake-down roll body 30 to rotate on the base 20.

[0046] like Figure 4 , Figure 5 and Figure 6 As shown below, the specific structure of the take-up and unwinding drum 30 will be described:

[0047] The winding and unwinding drum body 30 includes: drum body 100, fixed shaft 200, and movable pressure plate 300.

[0048] The fixed shaft 200 and the movable pressure plate 300 are housed inside the drum body 100. The central axis of the fixed shaft 200 is parallel to the central axis of the drum body 100 but not on the same straight line.

[0049] The movable pressure plate 300 extends along the central axis of the drum body 100, such as Figure 7 and Figure 8 As shown, the movable clamping plate 300 has an elastic part 310, a rotating part 320, and a clamping part 330 connected in sequence. The rotating part 320 is bent and clamped on the fixed shaft 200. The elastic part 310 and the clamping part 330 are located at the two ends of the rotating part 320, respectively.

[0050] like Figure 5 and Figure 6 As shown, the take-up and unwind spool body 30 also includes a rotation blocking shaft 400 and a reset blocking shaft 500 housed inside the spool body 100. The rotation blocking shaft 400 is used to block the elastic part 310, and the reset blocking shaft 500 is used to block the pressing part 330.

[0051] like Figure 4 As shown, the drum body 100 has a feed inlet 110 on its drum wall, and the inside of the drum body 100 has a pressing surface 120 located at the feed inlet 110 (as shown). Figure 5 and Figure 6 As shown), the pressing part 330 contacts or separates from the pressing surface 120.

[0052] like Figure 9 As shown, the specific structure of the drive device 40 will be described below:

[0053] The drive unit 40 includes: a telescopic drive mechanism 600 and a rotation drive mechanism 700.

[0054] The rotary drive mechanism 700 is provided with a main drive rod 710, and the end of the drum body 100 is provided with a main arc-shaped through hole 130 corresponding to the main drive rod 710 (e.g., Figure 4 (As shown).

[0055] The telescopic drive mechanism 600 drives the rotary drive mechanism 700 to extend or retract, so that the main drive rod 710 enters or exits the interior of the drum body 100 through the main arc-shaped through hole 130.

[0056] The rotation drive mechanism 700 drives the main drive rod 710 to rotate, so that the main drive rod 710 drives the movable pressure plate 300 to rotate, thereby driving the drum body 100 to rotate.

[0057] In this embodiment, the telescopic drive mechanism 600 is a cylinder-driven structure, and the rotation drive mechanism 700 is a motor-driven structure.

[0058] The working principle of the above-mentioned polyester Mylar tape production equipment 10 will now be explained in conjunction with the take-up and untake-down drum 30 and the drive device 40:

[0059] like Figure 1 and Figure 2 As shown, under the guidance of the guide roller 51 and the action of gravity, one end of the polyester Mylar tape 50 is suspended and naturally extended. The suspended and naturally extended end of the polyester Mylar tape 50 falls from top to bottom and enters the interior of the roll body 100 through the feed port 110.

[0060] like Figure 10 As shown, when one end of the polyester Mylar tape 50 enters the inside of the roll body 100, the telescopic drive mechanism 600 drives the rotation drive mechanism 700 to extend, so that the main drive rod 710 enters the inside of the roll body 100 through the main arc-shaped through hole 130.

[0061] like Figure 11 As shown, immediately afterward, the rotation drive mechanism 700 drives the main drive rod 710 to rotate. The main drive rod 710 will first touch the pressing part 330, and the pressing part 330 will then drive the entire movable pressing piece 300 to rotate. During the rotation of the movable pressing piece 300, the elastic part 310 will be blocked by the rotation blocking shaft 400 (the elastic part 310 also begins to accumulate elastic force), so the movable pressing piece 300 stops rotating.

[0062] like Figure 12 As shown, although the movable pressing plate 300 stops rotating, the pressing part 330 continues to be deformed by the driving force of the main drive rod 710 until the pressing part 330 is pressed onto the pressing surface 120 (at this time, one end of the polyester Mylar tape 50 is clamped between the pressing part 330 and the pressing surface 120).

[0063] like Figure 12As shown, the pressing part 330 continues to be driven by the main drive rod 710. Since the pressing part 330 has been pressed against the pressing surface 120 and cannot continue to deform, the main drive rod 710 will drive the entire drum body 100 to rotate through the movable pressing piece 300 and the fixed shaft 200.

[0064] Since one end of the polyester Mylar tape 50 has been clamped, the polyester Mylar tape 50 will not come off the feed port 110 the moment the roll body 100 rotates. As the roll body 100 continues to rotate, the polyester Mylar tape 50 can be continuously wound around the roll body 100 to achieve winding.

[0065] It is worth noting that although the elastic part 310 will be blocked by the rotation blocking shaft 400 first, the drum body 100 will not rotate temporarily. To achieve the rotation of the drum body 100, a greater driving force is required. Therefore, the pressing part 330 will deform and press against the pressing surface 120 before the rotation of the drum body 100. After the pressing part 330 presses against the pressing surface 120, the entire movable pressing piece 300 is completely positioned and can no longer move. Thus, the main drive rod 710 can drive the entire drum body 100 to rotate through the movable pressing piece 300 and the fixed shaft 200.

[0066] It should also be noted that, in this invention, the most important purpose of using a rotating blocking shaft 400 to block the elastic part 310 is to allow the elastic part 310 to accumulate elastic force. This prepares the subsequent smooth and unobstructed unwinding of the polyester Mylar tape 50 from the roll body 100. A detailed explanation follows:

[0067] After the main drive rod 710 is pulled out from the inside of the roll body 100, the main drive rod 710 no longer abuts against the pressing part 330, the elastic force accumulated in the elastic part 310 will be released, the entire movable pressing piece 300 will rotate in the opposite direction, so the pressing part 330 will no longer press against the pressing surface 120, and one end of the polyester Mylar tape 50 will no longer be clamped by the pressing part 330 and the pressing surface 120 and will be in a free state. In this way, in the final stage of unwinding the roll body 100, the end of the polyester Mylar tape 50 that was originally clamped can be smoothly pulled out from the feed port 110.

[0068] It should also be noted that by setting the reset blocking shaft 500 to block the pressing part 330, the entire movable pressing piece 300 can be prevented from overstepping during the reverse rotation, so that the main drive rod 710 can be accurately inserted into the drum body 100 again to prepare.

[0069] From the above, it can also be seen that the structure of the movable pressure plate 300 is simple yet sophisticated, and its rotating part 320 is obtained by bending (as shown in the image). Figure 8 As shown, on the one hand, the bent rotating part 320 can be quickly and stably engaged with the fixed shaft 200; on the other hand, the bent rotating part 320 can cause the entire movable pressing plate 300 to rotate around the fixed shaft 200.

[0070] Regarding the cooperation between the rotating part 320 and the fixed shaft 200, the following implementation method is available:

[0071] In this embodiment, the rotating part 320 and the fixed shaft 200 are in clearance fit, meaning that a gap will be generated between the rotating part 320 and the fixed shaft 200. The rotating part 320 is not tightly clamped onto the fixed shaft 200, which facilitates the smooth rotation of the entire movable pressure plate 300. Even during the unwinding process, as long as the rotation speed of the drum body 100 reaches a certain level and continues to rotate, the movable pressure plate 300 will not wobble. This is because the central axis of the fixed shaft 200 is parallel to the central axis of the drum body 100 but not on the same straight line (the fixed shaft 200 is located at an eccentric position of the drum body 100). During the rotation of the drum body 100, the movable pressure plate 300 is fixed by centrifugal force.

[0072] In other embodiments, the rotating part 320 and the fixed shaft 200 are in frictional engagement, that is, the rotating part 320 is clamped on the fixed shaft 200, and friction is generated between the rotating part 320 and the fixed shaft 200. This friction is kept moderate, so that the elastic force accumulated by the elastic part 310 can cause the movable pressure plate 300 to rotate in the opposite direction and return to its original position. During the subsequent unwinding process, due to the presence of this friction, even if the rotation speed of the drum body 100 is not very fast (or rotates intermittently), the movable pressure plate 300 is unlikely to wobble.

[0073] In this invention, the rotation drive mechanism 700 is provided with a secondary drive rod 720 (e.g., Figure 9 As shown), the end of the drum body 100 is provided with a secondary arc-shaped through hole 140 corresponding to the secondary drive rod 720 (as shown). Figure 4 (As shown). It should be noted that the auxiliary drive rod 720 does not contact the pressing part 330 of the movable pressing plate 300 mentioned above. The auxiliary drive rod 720 only contacts the drum body 100. The auxiliary drive rod 720 is to cooperate with the main drive rod 710 so that the entire drum body 100 is subjected to more uniform force during rotation.

[0074] like Figure 3As shown, in other embodiments, there are two drive devices 40, which are respectively located at both ends of the drum body 100. The drive devices 40 drive the drum body 100 from both ends, which can reduce the length of the main drive rod 710 and the auxiliary drive rod 720 extending into the drum body 100.

[0075] The present invention also discloses a process for producing polyester Mylar tape, wherein the polyester Mylar tape is wound into a take-up and unwinding roll body by means of the above-mentioned polyester Mylar tape production equipment 10.

[0076] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
