Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of double-sided tape winding devices, and more specifically, to an acrylic foam double-sided tape winding device. Background Technology
[0002] Acrylic foam double-sided tape is a double-sided adhesive material made by coating both sides of a foam substrate with a strong acrylic adhesive and covering it with release paper or release film. Due to its strong adhesion, good holding power, UV protection, temperature resistance, water resistance, solvent resistance and plasticity, it is widely used in electronics, home furnishings and automobiles and other fields.
[0003] Acrylic foam double-sided tape consists of a gel and a protective layer. Both sides of the gel are adhesive, so a protective layer is needed to isolate and protect the wrapped gel to prevent them from sticking together. However, when using acrylic foam double-sided tape, the protective layer often becomes too long, causing it to fall to the ground. If a user accidentally steps on the protective layer, it may cause a fall. Furthermore, the unwrapped protective layer takes up a large area, seriously affecting the usability of the tape.
[0004] Therefore, there is a need to develop a device that can hand-roll the protective body of acrylic foam double-sided tape during use. Utility Model Content
[0005] Based on this, in order to solve the problems mentioned in the background art, the present invention provides an acrylic foam double-sided adhesive winding device, the specific technical solution of which is as follows: An acrylic foam double-sided tape winding device includes a base frame, a winding roller and a winding assembly. The base frame is set in an arch shape, consisting of a first frame, a second frame and a third frame connected in sequence, with the first and third frames arranged in parallel. The two ends of the winding roller are detachably and movablely connected to the middle of the first and third frames, respectively, and the winding roller is wrapped with unused double-sided tape. The take-up assembly includes a receiving roller, a rotating roller, and a fixed roller. One end of the receiving roller is movably connected to one side of the first frame, and one end of the fixed roller is movably connected to one side of the third frame. The receiving roller and the fixed roller are spaced apart. The rotating roller is telescopically disposed inside the fixed roller, and one end of the rotating roller telescopically engages with the other end of the receiving roller.
[0006] In some embodiments, a circular receiving groove is provided inward at one end of the receiving roller facing the rotating roller, and a snap-fit groove is provided along the inner sidewall of the receiving groove.
[0007] In some embodiments, the card slot is folded into three sections, namely the first section, the second section, and the third section; The first section is opened along the positive axis of the receiving slot; The second section is opened along the circumference of the receiving slot; The third section is opened along the reverse axis of the receiving slot; The first, second, and third paragraphs connect sequentially.
[0008] In some embodiments, there are at least three slots.
[0009] In some embodiments, the first segment extends through to the end face of the receiving roller.
[0010] In some embodiments, a spring is provided at the bottom of the receiving slot.
[0011] In some embodiments, a rotating groove is provided on the section of the fixed roller near the third frame, and a receiving groove is provided on the section of the fixed roller near the first frame. The rotating groove and the receiving groove are connected to penetrate the fixed roller, and the inner diameter of the receiving groove is larger than the inner diameter of the rotating groove.
[0012] In some embodiments, the rotating roller can be divided into a guide section and a docking section, the guide section and the docking section are integrally arranged, the docking section is located in the receiving groove and moves, a part of the guide section is located in the rotating groove and moves, the rotating roller can rotate relative to the fixed roller, and the rotating roller can extend and retract relative to the fixed roller. The side wall of the docking section is equipped with snap-fit parts, and the number and size of the snap-fit parts are matched with the snap-fit slots.
[0013] In some embodiments, a first groove is further provided at the bottom of the receiving slot, and a spring is installed in the first groove.
[0014] In some embodiments, a straight plate is provided on the end face of the rotating roller facing the first frame, and a snap-fit member is provided at the end of the straight plate.
[0015] The beneficial effects of this solution are as follows: The rotating docking section drives the receiving roller to rotate, causing the protective material of the double-sided adhesive to continuously wrap around the rotating roller, effectively preventing the protective material from falling off randomly. When the double-sided adhesive is used up, the rotating roller is first pushed to disengage the locking element from the third section, then the rotating roller is rotated to disengage the locking element from the second section. Finally, the rotating roller is driven to extend and retract, causing the docking section of the rotating roller to retract towards the receiving groove while the locking element disengages from the first section. At this time, there is a gap between the fixed roller and the receiving roller. Until the rotating roller retracts towards the receiving groove, the protective material wrapped around the rotating roller is blocked by one end of the fixed roller, allowing it to fall through the gap. The protective material wrapped around the rotating roller is relatively small, making it easier to collect. Attached Figure Description

[0021] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.
[0022] like Figure 1 As shown, an acrylic foam double-sided tape winding device according to one embodiment of the present invention includes a base frame 1, a winding roller 2 and a winding assembly 3. The base frame 1 is arranged in three arched sections, namely a first frame 11, a second frame 12 and a third frame 13 connected in sequence. The first frame 11 and the third frame 13 are arranged in parallel. The two ends of the winding roller 2 are detachably and movably connected to the middle of the first frame 11 and the third frame 13, respectively, and the winding roller 2 is wrapped with unused double-sided tape 100. like Figures 1-6 As shown, the take-up assembly 3 includes a receiving roller 31, a rotating roller 32, and a fixed roller 33. One end of the receiving roller 31 is movably connected to the first frame 11, and the other end of the receiving roller 31 has a circular receiving groove 311. At least three snap-fit grooves 3111 are evenly formed along the edge of the receiving groove 311 at the end of the receiving roller 31 with the receiving groove 311. The snap-fit groove 3111 is divided into three segments: a first segment 3111a, a second segment 3111b, and a third segment 3111c. The first segment 3111a is formed along the axial direction of the inner wall of the receiving groove 311, the second segment 3111b is formed along the circumferential direction of the inner wall of the receiving groove 311, and the third segment 3111c is formed along the axial direction of the inner wall of the receiving groove 311, with the opening direction of the third segment 3111c facing the end of the receiving roller 31 with the receiving groove 311. The first segment 3111a, the second segment 3111b, and the third segment 3111c are sequentially connected. A spring 3112 is provided at the bottom of the receiving slot 311.
[0023] like Figure 2 and Figure 4 As shown, one end of the fixed roller 33 is movably connected to the third frame 13. A rotating groove 331 is formed on the section of the fixed roller 33 near the third frame 13, and a receiving groove 332 is formed on the end of the fixed roller 33 near the first frame 11. The rotating groove 331 and the receiving groove 332 are connected to penetrate the fixed roller 33. The inner diameter of the receiving groove 332 is larger than the inner diameter of the rotating groove 331. The fixed roller 33 and the receiving roller 31 are spaced apart.
[0024] Furthermore, the third frame 13 has a through hole 131, and a bearing is installed in the through hole 131. One end of the fixed roller 33 is movably connected to the third frame 13 through the bearing.
[0025] like Figure 6 As shown, the rotating roller 32 can be divided into a guide section 321 and a docking section 322. The guide section 321 and the docking section 322 are integrally arranged. The guide section 321 passes through the receiving groove 332, the rotating groove 331 and the through hole 131 in sequence, so that the docking section 322 is located in the receiving groove 332. The rotating roller 32 can rotate relative to the fixed roller 33, and the rotating roller 32 can extend and retract relative to the fixed roller 33.
[0026] A snap-fit member 323 is provided on the side wall of the docking section 322. One end of the guide section 321 abuts against the spring 3112 and overcomes the reaction force of the spring 3112, so that the snap-fit member 323 can be inserted into the first section 3111a. By rotating the rotating roller 32, the snap-fit member 323 enters the second section 3111b. Then, the reaction force of the spring 3112 drives the rotating roller 32 to move away from the receiving roller 31. When the snap-fit member 323 is snapped into the third section 3111c, the spring 3112 will fix the rotating roller 32 and the receiving roller 31 in a fixed connection.
[0027] like Figures 1-8 As shown, in use, the initial state of an acrylic foam double-sided tape winding device is that the snap-fit part 323 of the rotating roller 32 is snapped into the snap-fit groove 3111, that is, the fixed roller 33 and the receiving roller 31 are connected through the rotating roller 32. The specific operating steps are as follows: First, remove the winding roller 2. Then, attach the unused double-sided tape 100 to the winding roller 2. Pull one end of the double-sided tape 100 to separate the adhesive 100a from the protective body 100b. The protective body 100b is then wound around the docking section 322 of the rotating roller 32 to begin using the double-sided tape 100. During use, rotating the docking section 322 causes the receiving roller 31 to rotate, resulting in the protective body 100b of the double-sided tape 100 continuously winding around the rotating roller 32.
[0028] When the adhesive 100a of the double-sided tape 100 is used up, the rotating roller 32 is pushed first to disengage the snap fastener 323 from the third section 3111c. Then the rotating roller 32 is rotated to disengage the snap fastener 323 from the second section 3111b. Finally, the rotating roller 32 is driven to extend and retract, so that the mating section 322 of the rotating roller 32 retracts towards the receiving groove 332, and the snap fastener 323 disengages from the first section 3111a. At this time, the fixed roller 33 and the receiving roller 31 are spaced apart. Until the rotating roller 32 retracts towards the receiving groove 332, the protective body 100b wrapped around the rotating roller 32 is blocked by one end of the fixed roller 33, so the protective body 100b falls through the gap between the fixed roller 33 and the receiving roller 31. The fallen protective body 100b is due to
[0029] The number of the snap-fit slots 3111 and snap-fit pieces 323 is preferably three.
[0030] Example 2 like Figure 7 and Figure 8 As shown, the difference from Embodiment 1 is that the snap-fit groove 3111 is located at the bottom of the receiving groove 311, and a first groove 3113 is also provided at the bottom of the receiving groove 311. The first groove 3113 is used to house the spring 3112. The spring 3112 extends beyond the first groove 3113 and protrudes into the receiving groove 311.
[0031] A straight plate 324 is provided on the docking section 322 facing the first frame 11. A snap-fit member 323 is provided at the end of the straight plate 324. The first section 3111a of the snap-fit groove 3111 is adapted to the straight plate 324 and the snap-fit member 323, meaning the straight plate 324 and the snap-fit member 323 can be inserted into the first section 3111a. The second section 3111b of the snap-fit groove 3111 is adapted to the straight plate 324, meaning that by rotating the rotating roller 32, the straight plate 324 and the snap-fit member 323 can move to the end of the second section 3111b (i.e., the position of the third section 3111c). The third section 3111c of the snap-fit groove 3111 is adapted to the snap-fit member 323, meaning that when the spring 3112 acts on the docking section 322 of the rotating roller 32, the rotating roller 32 retracts towards the third frame 13, at which time the snap-fit member 323 is held in the third section 3111c.
[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
