Description

Technical Field

[0001] This invention relates to the field of film tape production equipment technology, specifically to a glue dispensing device for the production of antistatic PTFE film tape. Background Technology

[0002] Antistatic PTFE film tape uses polytetrafluoroethylene (PTFE) molding raw material, which is molded and sintered on a high-cleanliness, dust-free production line. A unique, precise, and high-precision process is used to cut a high-quality PTFE film as the tape base. The adhesive is prepared by coating one side of the PTFE film with a layer of silicone pressure-sensitive adhesive, resulting in a PTFE film-attached or roll-shaped pressure-sensitive self-adhesive tape. The existing technology has the following problems:

[0003] Because the glue dispensing device used in the production of existing antistatic PTFE film tapes is fixed in position, the height of the glue dispensing device cannot be adjusted when dispensing glue for films of different thicknesses, resulting in uneven glue dispensing. Summary of the Invention

[0004] This invention provides a dispensing device for producing antistatic PTFE film tape, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] A dispensing device for producing antistatic PTFE film tape includes a dispensing platform. A tape limiting plate is fixedly installed on the outer wall of the top middle section of the dispensing platform. A limiting wheel is provided on the front outer wall of the tape limiting plate. An extension plate is fixedly installed on the front outer wall of the dispensing platform. A bracket is fixedly installed on the top outer wall of the extension plate. A film wheel is movably installed between the inner and outer walls of the bracket. A winding bracket is fixedly installed on the rear top outer wall of the dispensing platform. A winding motor is fixedly installed on the left outer wall of the winding bracket. A tape winding wheel is fixedly installed on the outer wall of the output shaft of the winding motor.

[0007] The top outer wall of the adhesive dispensing platform is fixedly installed with a platform shell.

The bottom outer wall of the storage cylinder base is fixedly installed with a connecting pipe. The connecting pipe is located inside the platform shell. The bottom outer wall of the connecting pipe is fixedly connected with an adhesive conveying plate. The bottom outer wall of the adhesive conveying plate is fixedly installed with an applicator head.

[0008] A lifting threaded rod is movably installed on the inner wall of the bottom left side of the tape limiting plate. A lifting plate is movably installed on the outer wall of the threaded rod. An adjustment knob is fixedly installed on the outer wall of the top of the lifting threaded rod. A connecting rod is fixedly installed on the outer wall of the right side of the lifting plate. A lifting column is fixedly installed on the outer wall of the top of the connecting rod. An adjustment plate is fixedly installed on the outer wall of the top of the lifting column. The side of the adjustment plate overlaps with the inner wall of the groove at the top center of the tape limiting plate.

[0009] A further improvement of the technical solution of the present invention is that: the outer walls of the left and right ends of the front top of the glue dispensing platform are fixedly installed with clips, and the outer walls of the clips are fitted with protective covers.

[0010] A further improvement of the technical solution of the present invention is that a dustproof plate is snapped onto the top outer wall of the bracket, and the dustproof plate is located above the film wheel.

[0011] A further improvement of the technical solution of the present invention is that: an adjustment box is fixedly installed on the front outer wall of the adhesive conveying plate, and a beveled pressure plate is provided through the bottom inner wall of the adjustment box, and the outer wall of the beveled pressure plate overlaps with the inner wall of the middle groove side of the tape limiting plate.

[0012] A further improvement of the technical solution of the present invention is that a threaded rod is movably installed on the front outer wall of the inclined pressure plate, and the outer wall of the threaded rod penetrates the front outer wall of the adjustment box.

[0013] A further improvement of the technical solution of the present invention is that: a fixing knob is threadedly installed on the outer wall of the front end of the threaded rod, and an anti-slip pad is fixedly installed on the outer wall of the rear side of the fixing knob, and the outer wall of the rear side of the anti-slip pad overlaps with the outer wall of the front side of the adjustment box.

[0014] A further improvement of the technical solution of the present invention is that: a drying box is fixedly installed on the top outer wall of the platform shell, and ventilation holes are opened on the left and right inner walls of the rear top of the platform shell, and the inner walls of the ventilation holes are connected to the holes on the left and right sides of the bottom of the drying box.

[0015] A further improvement of the technical solution of the present invention is that: an air inlet fan is fixedly installed in the inner cavity on both the left and right sides of the drying box, the air inlet fan is located above the ventilation hole, and an air inlet is provided on the outer wall of both the left and right sides of the top of the drying box, and a filter screen is provided on the inner wall of the air inlet.

[0016] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0017] 1. This invention provides a dispensing device for producing antistatic PTFE film tape. It employs a dispensing platform, tape limiting plate, limiting wheel, lifting threaded rod, adjusting knob, lifting plate, connecting rod, lifting column, adjusting plate, winding bracket, winding motor, tape winding wheel, film wheel, and applicator head. During dispensing, a section of film from the film wheel is passed through the limiting wheel and then pressed against the central groove of the tape limiting plate, and then fixed onto the tape winding wheel. The winding motor is then started to wind the dispensed tape. When films of varying thicknesses are required, [further details can be added]. Rotating the adjustment knob drives the lifting threaded rod to rotate, which in turn causes the lifting plate to rise along the connecting rod. This, in turn, uses the lifting column to lift the adjusting plate in the groove at the middle of the tape limiting plate. This allows the distance between the film and the applicator head to be adjusted. This solves the problem that the glue dispensing device used in the production of antistatic PTFE film tape is fixed in position, which makes it impossible to adjust the height of the glue dispensing device when dispensing glue for films of different thicknesses, resulting in uneven glue dispensing. This invention achieves the goal of making the glue dispensing device adaptable to films of different thicknesses and ensuring uniform glue dispensing.

[0018] 2. This invention provides a glue dispensing device for the production of antistatic PTFE film tape. It adopts the cooperation of a clip, a protective cover, a bracket, and a dustproof clip. By aligning the protective cover with the clip and snapping it in, the entire tape limiting plate can be shielded. At the same time, by snapping the dustproof clip onto the bracket, the film wheel can be shielded, thereby preventing dust from adhering to the surface of the film during normal conveying. This achieves the effect of keeping the film clean before glue dispensing and ensuring the normal adhesion of the adhesive.

[0019] 3. This invention provides a glue dispensing device for the production of antistatic PTFE film tape. It adopts a combination of a drying box, air inlet, filter screen, inlet fan, and ventilation hole. When the adhesive is applied to the film and continues to be wound and conveyed, it will pass under the ventilation hole. By utilizing the rotation of two inlet fans in the drying box, the outside air can be filtered through the filter screen in the air inlet and then pass through the ventilation hole to quickly dry the adhesive. This achieves the effect of quickly drying the adhesive during tape winding, avoiding adhesive dripping after winding, and reducing waste. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to embodiments:

[0029] Example 1

[0030] like Figure 1-7As shown, this invention provides a dispensing device for producing antistatic PTFE film tape, including a dispensing platform 1. A tape limiting plate 12 is fixedly installed on the outer wall of the top middle section of the dispensing platform 1. A limiting wheel 121 is provided on the front outer wall of the tape limiting plate 12. An extension plate 5 is fixedly installed on the front outer wall of the dispensing platform 1. A bracket 51 is fixedly installed on the top outer wall of the extension plate 5. A film wheel 511 is movably installed between the inner and outer walls of the bracket 51. A winding bracket 13 is fixedly installed on the rear top outer wall of the dispensing platform 1. A winding motor 131 is fixedly installed on the left outer wall of the winding bracket 13. A tape winding wheel 132 is fixedly installed on the outer wall of the output shaft of the winding motor 131. A platform shell 2 is fixedly installed on the top outer wall of the dispensing platform 1. A storage cylinder base 41 is fixedly installed on the front top outer wall of the platform shell 2. The top inner wall of the storage cylinder base 41 extends through... An adhesive storage cylinder 4 is threadedly installed. A connecting pipe 42 is fixedly installed through the bottom outer wall of the storage cylinder base 41. The connecting pipe 42 is located inside the platform shell 2. An adhesive conveying plate 43 is fixedly connected to the bottom outer wall of the connecting pipe 42. An applicator head 431 is fixedly installed on the bottom outer wall of the adhesive conveying plate 43. A lifting threaded rod 122 is movably installed on the bottom inner wall of the left side of the tape limiting plate 12. A lifting plate 124 is movably installed on the threaded outer wall of the lifting threaded rod 122. An adjusting knob 123 is fixedly installed on the top outer wall of the lifting threaded rod 122. A connecting rod 125 is fixedly installed on the right outer wall of the lifting plate 124. A lifting column 126 is fixedly installed on the top outer wall of the connecting rod 125. An adjusting plate 127 is fixedly installed on the top outer wall of the lifting column 126. The side of the adjusting plate 127 overlaps with the inner wall of the groove at the top center of the tape limiting plate 12.

[0031] In this embodiment, during adhesive preparation, the film wound on a section of film roller 511 is passed through the limiting roller 121 and then pressed against the middle groove of the tape limiting plate 12, and then fixed on the tape take-up roller 132. When films of different thicknesses are required, the lifting threaded rod 122 can be rotated by rotating the adjustment knob 123, thereby causing the lifting plate 124 to drive the connecting rod 125 to rise. Then, the adjusting plate 127 in the middle groove of the tape limiting plate 12 is raised by the lifting column 126, so that the distance between the film and the applicator head 431 can be adjusted. Then, the small pump in the adhesive conveying plate 43 can use the applicator head 431 to evenly apply the adhesive in the detachable adhesive storage cylinder 4 at the top of the storage cylinder base 41 to the top surface of the film through the connecting pipe 42. Then, the prepared tape is wound up by starting the take-up motor 131.

[0032] Example 2

[0033] like Figure 1-7As shown, based on Embodiment 1, the present invention provides a technical solution: preferably, the outer walls of the left and right ends of the front top of the glue dispensing platform 1 are fixedly installed with clips 11, the outer walls of the clips 11 are snapped with protective covers 6, the top outer wall of the bracket 51 is snapped with a dustproof clip plate 512, and the dustproof clip plate 512 is located above the film wheel 511.

[0034] In this embodiment, the protective cover 6 can be inserted into the clip 11 to cover the entire tape limiting plate 12. At the same time, the dustproof clip 512 can be inserted into the bracket 51 to cover the film wheel 511. With the protective cover 6, dust can be prevented from adhering to the surface of the antistatic PTFE film during normal transport, keeping the surface of the antistatic PTFE film clean.

[0035] Example 3

[0036] like Figure 1-7 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, an adjustment box 44 is fixedly installed on the front outer wall of the adhesive conveying plate 43, and a beveled pressure plate 441 is provided through the bottom inner wall of the adjustment box 44. The outer wall of the beveled pressure plate 441 overlaps with the inner wall of the middle groove side of the tape limiting plate 12. A threaded rod 442 is movably installed on the front outer wall of the beveled pressure plate 441. The outer wall of the threaded rod 442 penetrates the front outer wall of the adjustment box 44. A fixing knob 443 is threadedly installed on the front outer wall of the threaded rod 442. An anti-slip pad 4431 is fixedly installed on the rear outer wall of the fixing knob 443. The rear outer wall of the anti-slip pad 4431 overlaps with the front outer wall of the adjustment box 44.

[0037] In this embodiment, by rotating the fixing knob 443 on the front side of the adjustment box 44, the fixing knob 443 can be moved forward, and the inclined pressure plate 441 can be lowered, thereby pressing and limiting the top surface of the film. Then, by reversing the fixing knob 443, it can be moved backward, and the anti-slip pad 4431 is used to press and stick to the outer wall of the front side of the adjustment box 44 for fixation, thereby pressing and limiting the film that has been adjusted in height.

[0038] Example 4

[0039] like Figure 1-7 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, a drying box 3 is fixedly installed on the top outer wall of the platform shell 2, ventilation holes 21 are opened on the left and right inner walls of the rear top of the platform shell 2, the inner walls of the ventilation holes 21 are connected to the holes on the left and right sides of the bottom of the drying box 3, an air inlet fan 32 is fixedly installed on the left and right inner cavities of the drying box 3, the air inlet fan 32 is located above the ventilation holes 21, an air inlet 31 is provided on the top left and right outer walls of the drying box 3, and a filter screen 311 is provided on the inner wall of the air inlet 31.

[0040] In this embodiment, as the adhesive is applied to the film and continues to be rolled up and conveyed, it passes under the ventilation hole 21 at the top rear side of the platform housing 2. By utilizing the rotation of the two intake fans 32 inside the drying box 3, external air is filtered through the filter screen 311 inside the air inlet 31 to remove impurities and then passes through the ventilation hole 21 to quickly dry the adhesive.

[0041] The working principle of the adhesive dispensing device for the production of antistatic PTFE film tape will be explained in detail below.

[0042] like Figure 1-7 As shown, during adhesive application, the film wound on a section of film roller 511 is passed through the limiting roller 121 and then pressed against the middle groove of the tape limiting plate 12, and then fixed on the tape take-up roller 132. When films of different thicknesses are required, the lifting threaded rod 122 can be rotated by rotating the adjusting knob 123, thereby causing the lifting plate 124 to drive the connecting rod 125 to rise. This, in turn, uses the lifting column 126 to drive the adjusting plate 127 in the middle groove of the tape limiting plate 12 to rise, thus allowing the distance between the film and the applicator head 431 to be adjusted. Then, by rotating the fixing knob 443 on the front side of the adjusting box 44, the fixing knob 443 can be moved forward, and the inclined pressure plate 441 can be lowered, thereby pressing and limiting the top surface of the film. Reversing the fixing knob 443 allows the device to move backward. The anti-slip pad 4431 is used to press and press against the front outer wall of the adjustment box 44 for fixation. Then, the small pump in the adhesive conveying plate 43 can use the connecting pipe 42 to evenly apply the adhesive from the detachable adhesive storage cylinder 4 at the top of the storage cylinder base 41 onto the top surface of the film using the application head 431. Then, the winding motor 131 is started to wind up the prepared adhesive tape. As the adhesive is applied to the film and continues to be wound and conveyed backward, it will pass under the ventilation hole 21 at the top rear side of the platform shell 2. The rotation of the two inlet fans 32 in the drying box 3 will allow the outside air to pass through the filter screen 311 in the air inlet 31 to filter impurities and then pass through the ventilation hole 21 to quickly dry the adhesive.

[0043] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
