Technical Field

[0001] The utility model relates to the technical field of the production of double-sided adhesive tapes, in particular to a production device for a heat-conducting double-sided adhesive tape. Background Technique

[0002] The heat-conducting double-sided adhesive tape is composed of an acrylic polymer filled with heat-conducting ceramic powder and compounded with an organic silicone adhesive. It has the characteristics of high heat conduction and insulation. In the process of the existing production of heat-conducting double-sided adhesive tapes, the heat-conducting double-sided adhesive tapes are generally cut.

The utility model relates to the technical field of the production device of double-sided adhesive tapes, and discloses a production device for a heat-conducting double-sided adhesive tape, including a cutting body. A rectangular protrusion is arranged at the top of one side of the front of the cutting body. A power box is fixedly installed at the bottom of the rectangular protrusion part. A cutter disc is fixedly installed at the bottom of the power box. Bases are fixedly installed at the four corners of the bottom of the cutting body, and a bottom plate is fixedly installed at the bottom of the bases. For this production device of the heat-conducting double-sided adhesive tape, by setting a screw rod and a guiding plate, before cutting the heat-conducting double-sided adhesive tape, first rotate the screw rod according to the width of the tape to be cut to adjust the distance between the two guiding plates. And there are scales on the rectangular block, making the position of the guiding plate easier to adjust. The right end of the guiding plate is designed to be inclined outward. The guiding plate plays a role in restricting the heat-conducting tape, avoiding the tape from shifting during the cutting process and improving the practicability of the device.

[0004] Based on the retrieval of the above patent and the combination with the devices in the prior art, it is found that when the above device is applied, although it can solve the problem that there is no tape limiting device on the die-cutting machine, making the tape prone to tilt during the cutting process, affecting the cutting effect.

However, during the use process, before cutting the heat-conducting double-sided adhesive tape, it is necessary to wind it on a roller first. However, the width specifications of the heat-conducting double-sided adhesive tapes on the market are different. However, there are no movable blocking objects at both ends during the winding of the roller, thus affecting the neatness of the winding. Eventually, the unwound heat-conducting double-sided adhesive tape tilts randomly, resulting in the cutting being inclined. Content of the Utility Model

However, there are no movable blocking objects at both ends during the winding of the roller, thus affecting the neatness of the winding. Eventually, the unwound heat-conducting double-sided adhesive tape tilts randomly, resulting in the cutting being inclined.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A production device for a heat-conducting double-sided tape, including a bottom plate, a workbench, a cutting device, a conveying device, a support rod and a roller.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The utility model solves the problem that before cutting the heat-conducting double-sided adhesive, it needs to be wound around a roller first. However, the width specifications of the heat-conducting double-sided adhesives on the market vary, and there are no movable blocking objects at both ends during the winding of the roller, which affects the neatness of winding. Eventually, the unwinding of the heat-conducting double-sided adhesive is inclined randomly, resulting in inclined cutting. By setting a spacing plate, when the heat-conducting double-sided adhesive is wound around the roller, the user adjusts the spacing between the two spacing plates according to the width of the heat-conducting double-sided adhesive, so as to limit and assist the winding of the heat-conducting double-sided adhesive on the roller, achieving the effect of assisting winding.

[0015] 2. The utility model improves the stability of the spacing plate when assisting the roller to wind the heat-conducting double-sided adhesive. By setting a fixing component, after the user adjusts according to the width of the heat-conducting double-sided adhesive, the user turns the knurled bolt on the extension ring until the knurled bolt abuts against the roller to generate an abutting force. Using the abutting force, the spacing plate is limited and fixed, preventing the spacing plate from sliding naturally when assisting the roller to wind the heat-conducting double-sided adhesive and losing the assisting effect.

[0016] 3. The utility model is provided with a self-centering mechanism. When the user adjusts the spacing between the two spacing plates according to the width of the heat-conducting double-sided adhesive, one of the spacing plates is pushed, and the extension block moves along with it, and the toothed plate is pushed to move, causing the gear to rotate. Subsequently, through the rotation of the gear, the other toothed plate moves, and the other spacing plate is driven to move through the other extension block. Finally, the two spacing plates move symmetrically outward or inward simultaneously with the center point of the roller as the center, so as to facilitate the user to quickly adjust the spacing between the two spacing plates and improve work efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figures 1 to 3 shown, a production device for a heat-conducting double-sided tape provided by the present invention includes a bottom plate 1, a workbench 2, a cutting device 3, a conveying device 4, a support rod 5, and a roller 6. The four corners of the bottom of the workbench 2 are fixedly connected to the top of the bottom plate 1. The two sides of the bottom of the cutting device 3 are fixedly connected to the two sides of the bottom of the workbench 2. The two sides of the bottom of the conveying device 4 are fixedly connected to the front side and the rear side of the two sides of the top of the workbench 2. The bottom of the support rod 5 is fixedly connected to the two sides of the right side of the top of the bottom plate 1. The two sides of the surface of the roller 6 are slidably connected to the inner wall of the support rod 5. Spacing plates 7 are slidably connected to both sides of the surface of the roller 6. A fixing assembly 8 is fixedly connected to the outside of the spacing plate 7. A self-centering mechanism 9 is provided at the top of the roller 6.

[0023] Referring to Figure 1 and Figure 3 , the fixing assembly 8 includes an extension ring 81. The inner side of the extension ring 81 is fixedly connected to the outside of the spacing plate 7. The inner wall of the extension ring 81 is slidably connected to the surface of the roller 6. A knurled bolt 82 is provided on the right side of the extension ring 81. The left side of the knurled bolt 82 is threadedly penetrated to the right side of the inner wall of the extension ring 81.

[0024] As a technical optimization solution of the present invention, by setting the fixing assembly 8, after the user adjusts according to the width of the heat-conducting double-sided tape, the user turns the knurled bolt 82 on the extension ring 81 until the knurled bolt 82 abuts against the roller 6 to generate an abutting force. The spacing plate 7 is limited and fixed by using the abutting force, preventing the spacing plate 7 from sliding naturally when assisting the roller 6 to wind the heat-conducting double-sided tape and losing the assisting effect, thereby improving the stability of the spacing plate 7 when assisting the roller 6 to wind the heat-conducting double-sided tape.

[0025] Referring to Figure 1 and Figure 3 , the self-centering mechanism 9 includes a main body groove 91. The main body groove 91 is opened at the top of the roller 6. Opposite toothed plates 92 are slidably connected to the front side of the right inner wall and the rear side of the left inner wall of the main body groove 91. A gear 93 is provided inside the main body groove 91. The two sides of the gear 93 are meshed with the inner sides of the toothed plates. Extension blocks 94 are fixedly connected to the outside of the tops of the opposite toothed plates 92. The tops of the extension blocks 94 are fixedly connected to the tops of the inner walls of the spacing plates 7.

[0026] As a technical optimization solution of the present utility model, by setting the self-centering mechanism 9, when the user adjusts the distance between the two spacing plates 7 according to the width of the thermally conductive double-sided tape, pushing one of the spacing plates 7, the extension block 94 moves together, and the toothed plate 92 is pushed to move, so that the gear 93 rotates. Subsequently, through the rotation of the gear 93, the other toothed plate 92 moves, and drives the other spacing plate 7 to move through the other extension block 94, finally making the two spacing plates 7 move symmetrically outward or inward simultaneously with the center point of the roller 6 as the center, thus facilitating the user to quickly adjust the distance between the two spacing plates 7 and improving work efficiency.

[0027] Reference Figure 3 At the top of the gear 93, a T-shaped rod 10 is provided, and the bottom of the T-shaped rod 10 penetrates to the bottom of the gear 93 and is fixedly connected to the bottom of the inner wall of the main body groove 91.

[0028] As a technical optimization solution of the present utility model, by setting the T-shaped rod 10, during the process of the two toothed plates 92 being able to move symmetrically through the transmission of the gear 93, the gear 93 is limited and fixed by the T-shaped rod 10, so that the gear 93 stably transmits between the two toothed plates 92, preventing the gear 93 from naturally rising and disengaging from the meshing with the toothed plate 92 when driving the two toothed plates 92, thereby improving the stability of the gear 93 during transmission.

[0029] Reference Figure 3 On the left side of the knurled bolt 82, a rubber block 11 is fixedly connected, and the left side of the rubber block 11 is movably connected to both sides on the right side of the roller 6.

[0030] As a technical optimization solution of the present utility model, by setting the rubber block 11, when the knurled bolt 82 is screwed until the knurled bolt 82 abuts against the roller 6 to generate an abutting force, during the process of the spacing plate 7 being limited and fixed, as the knurled bolt 82 gradually approaches the roller 6, the rubber block 11 moves together and first contacts the roller 6, isolating the direct contact between the knurled bolt 82 and the roller 6. After that, as the knurled bolt 82 continues to move, the rubber block 11 will be squeezed and then deform along the surface of the roller 6, thereby increasing the contact area between the knurled bolt 82 and the roller 6 and improving the abutting force generated when the knurled bolt 82 abuts against the roller 6.

[0031] Reference Figure 2 And Figure 3 On the rear side on the right side of the roller 6, a scale groove 12 is opened, and a plurality of scale grooves 12 are opened and distributed at equal intervals.

[0032] As a technical optimization solution of the present utility model, by providing the scale groove 12, when adjusting the distance between the two spacing plates 7 according to the width of the thermally conductive double-sided tape, the user can quickly and accurately position and adjust the distance between the spacing plates 7 through the scale groove 12 on the roller 6, so that the roller 6 can quickly wind up the thermally conductive double-sided tape, thereby improving the work efficiency of the user.

[0033] Reference Figure 1 , a separator 13 is fixedly connected to the inner side of the spacing plate 7, and the separator 13 is made of polyethylene.

[0034] As a technical optimization solution of the present utility model, by providing the separator 13, when the spacing plate 7 assists the roller 6 in winding the thermally conductive double-sided tape, the contact between both sides of the thermally conductive double-sided tape and the spacing plate 7 is isolated by the separator 13, and due to the low surface energy characteristic of the polyethylene material of the separator 13, it is difficult for the separator 13 to be adhered, preventing the two ends of the thermally conductive double-sided tape from being scratched and adhered to the spacing plate 7 when the roller 6 neatly winds the thermally conductive double-sided tape through the limiting assistance of the spacing plate 7 and being difficult to tear off, which affects the subsequent unwinding. Thus, the stability of the spacing plate 7 in providing limiting assistance to the two ends of the thermally conductive double-sided tape is improved.

[0035] The working principle and usage process of the present utility model: When it is necessary to wind the thermally conductive double-sided tape onto the roller 6 for cutting, the user first adjusts the distance between the two spacing plates 7 on the roller 6 according to the width of the thermally conductive double-sided tape, pushes one of the spacing plates 7, and the extension block 94 moves along with it, and pushes the toothed plate 92 to move, causing the gear 93 to rotate. Subsequently, through the rotation of the gear 93, the other toothed plate 92 moves, and drives the other spacing plate 7 to move through the other extension block 94, moving the two spacing plates 7 symmetrically outward or inward simultaneously with the center point of the roller 6 as the center. Then, through the scale groove 12 on the roller 6, quickly and accurately position and adjust the distance between the two spacing plates 7 to reach the width of the thermally conductive double-sided tape required for the current cutting. At this time, turn the knurled bolt 82 on the extension ring 81 until the rubber block 11 on the knurled bolt 82 is squeezed, deforms and fits against the surface of the roller 6, generating a tightening force. Utilize the tightening force to limit and fix the spacing plate 7. Now, the roller 6 can be rotated to wind the thermally conductive double-sided tape roll, and it is limited and assisted by the spacing plate 7, and neatly and flatly wound on the roller 6. Subsequently, after the winding is completed, the thermally conductive double-sided tape can be pulled through under the conveying device 4 and the cutting device 3. At this point, the conveying device 4 and the cutting device 3 can be started to process the thermally conductive double-sided tape, thereby having the advantage of assisting winding.

[0036] In summary, for the production equipment of the heat-conducting double-sided tape, by setting the spacing plate 7, before cutting the heat-conducting double-sided tape, when it is wound around the roller 6, the user adjusts the spacing between the two spacing plates 7 according to the width of the heat-conducting double-sided tape, so as to provide limit assistance for the roller 6 to wind up the heat-conducting double-sided tape, solving the problem that before cutting the heat-conducting double-sided tape, it needs to be wound around the roller first, but the width specifications of the heat-conducting double-sided tapes on the market are different, and there are no movable blocking objects at both ends during the winding of the roller, thus affecting the neatness of the winding, and finally causing the unwinding heat-conducting double-sided tape to tilt randomly, resulting in the tilting of the cutting.
