Description

Technical Field

[0001] This utility model relates to the field of double-sided tape cutting technology, specifically a high-viscosity flame-retardant double-sided tape cutting device. Background Technology

[0002] High-adhesion flame-retardant double-sided tape is a special type of tape that combines high adhesion with flame retardancy. This tape is widely used in many fields such as electronics, construction, and automobiles. It is especially useful in situations where both adhesive strength and fire safety need to be considered. Its high adhesion ensures that the tape adheres firmly to various materials, while its flame retardancy provides additional safety in emergencies such as fires.

[0003] A search revealed a utility model patent with Chinese patent publication number CN217728823U, which discloses an automatic cutting device for high-adhesion double-sided tape. The device includes a housing, a cutting component, a transmission component, a snap-fit ​​component, and a through-hole. The housing has an through-hole at its upper end, and a cutting component is disposed at the upper end of the through-hole. The cutting component is horizontally disposed on the through-hole. A transmission component is disposed on the housing inside the through-hole, and a snap-fit ​​component is disposed on the housing below the transmission component. The snap-fit ​​component and the transmission component are interconnected.

[0004] The device described above achieves the cutting purpose by controlling the contact between the cutter and the double-sided tape. However, after the cutting is completed, some adhesive will adhere to the blade. If this adhesive is not treated, it will affect the sharpness of the blade as the thickness increases, indicating room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a high-viscosity flame-retardant double-sided tape cutting device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-adhesion flame-retardant double-sided tape cutting device, comprising an installation box, a cutting assembly installed inside the installation box, the cutting assembly being located at the bottom of the installation box, the cutting assembly comprising a mounting seat fixedly connected to the inner wall of one end of the installation box, two limiting rods fixedly connected to the outer wall of one side of the mounting seat, the two limiting rods being slidably fitted with the same connecting plate, and a spring being fitted on the outside of each of the two limiting rods, the two ends of the two springs being fixedly connected to the mounting seat and the connecting plate respectively.

[0007] As a further preferred embodiment of this technical solution, a cutter is installed on one side of the outer wall of the connecting plate by means of bolts, and the cutter is horizontally positioned. An abutment strip is fixedly connected to one side of the inner wall of the mounting box, and the position of the abutment strip corresponds to that of the cutter.

[0008] As a further preferred embodiment of this technical solution, a second mounting base is fixedly connected to the bottom of the inner wall of one end of the mounting box. The second mounting base is located on the side of the cutter. A horizontally arranged mounting frame is fixedly connected to the outer wall of one end of the second mounting base. Two symmetrically arranged scrapers are hinged to the outside of the mounting frame. Two springs are fixedly connected to the outer wall of the two scrapers at their ends that are far apart from each other. One end of each of the four springs is fixedly connected to the mounting frame.

[0009] This design allows the cutter to scrape both sides promptly as it retracts after completing its work, preventing adhesive from adhering to the cutter surface and ensuring its sharpness. With the thumb gripping the outer wall of the mounting box and the other two fingers pulling the connecting plate, the stress on spring one is overcome, causing it to lengthen. The connecting plate then slides along the limit rod. After the cutter contacts the scraper, the pressure applied by spring two is overcome, and the scraper rotates and is fitted outside the mounting bracket. Therefore, the cutter can push the scraper outwards, and the pressure of spring two is applied to the outer wall of the cutter through the scraper. With the cooperation of the abutment strip, the cutter completes the cutting operation. Releasing the connecting plate allows the cutter to return to its original position. As it passes the scraper, any remaining adhesive is scraped off and concentrated on one side of the cutting edge. The spring two ensures that the adhesive adheres to the cutter surface, facilitating effective cleaning.

[0010] As a further preferred embodiment of this technical solution, a fixing component is installed inside the mounting box, and the fixing component is located in the middle of the mounting box.

[0011] As a further preferred embodiment of this technical solution, the fixing component includes a rotating shaft rotatably connected to the inner wall of one end of the mounting box via a bearing, and the rotating shaft is internally threaded with multiple inclined screws, which are distributed at equal intervals.

[0012] The tape roll is placed outside the rotating shaft. Then, the screw is driven by the knob, which will rotate and move closer to the tape roll along the rotating shaft. Then, the other screws are adjusted repeatedly until multiple screws contact the inner wall of the tape roll and stop. At this time, the position of the tape roll will also be fixed, which helps to increase the adaptability of the device.

[0013] As a further preferred embodiment of this technical solution, a guide roller is rotatably connected to one corner of the inner wall of the mounting box via a bearing, and a release film is provided on the inner circumference of the guide roller.

[0014] As a further preferred embodiment of this technical solution, the bottom outer wall of an extension plate at the bottom of the mounting box is configured as an arc-shaped surface.

[0015] This utility model provides a high-adhesion flame-retardant double-sided tape cutting device, which has the following beneficial effects:

[0016] (1) By setting a cutting component, the cutter can scrape both sides of the blade in time when it retracts after completing the work, so as to avoid the adhesive adhering to the surface of the cutter and help ensure the sharpness of the cutter. The thumb holds the outer wall of the mounting box, and the other two fingers pull the connecting plate. The stress of the first spring is overcome and it becomes longer. The connecting plate will be driven to slide along the limit rod. After the cutter contacts the scraper, the pressure applied by the second spring is overcome, and the scraper rotates and is sleeved outside the mounting frame. Therefore, the cutter can push the scraper to flip outward. The pressure of the second spring will be applied to the outer wall of the cutter through the scraper. The cutter can complete the cutting work with the cooperation of the abutment strip. Then, the restriction of the connecting plate is released, and the cutter will return to its original position. When it passes the scraper, the adhesive residue on the surface will be scraped off and concentrated on one side of its blade. Under the action of the second spring, it can be ensured that it can adhere to the surface of the cutter, which is conducive to ensuring the cleaning effect.

[0017] (2) By setting a fixing component, the tape roll is sleeved outside the rotating shaft. Then, the screw is driven by the knob, which will rotate and move closer to the tape roll along the rotating shaft. Then, the other screws are adjusted repeatedly until the screws contact the inner wall of the tape roll and stop. At this time, the position of the tape roll will also be fixed, which helps to increase the adaptability of the device. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 2 , Figure 3 and Figure 4 As shown in this embodiment, a high-adhesion flame-retardant double-sided tape cutting device includes a mounting box 1. A cutting component 5 is installed inside the mounting box 1. The cutting component 5 is located at the bottom of the mounting box 1. The cutting component 5 includes a mounting base 501 fixedly connected to the inner wall of one end of the mounting box 1. Two limiting rods 502 are fixedly connected to the outer wall of one side of the mounting base 501. The same connecting plate 504 is slidably sleeved on the outside of the two limiting rods 502. A spring 503 is sleeved on the outside of each of the two limiting rods 502. The two ends of the two springs 503 are fixedly connected to the mounting base 501 and the connecting plate 504, respectively.

[0025] A cutter 505 is installed on one side of the outer wall of the connecting plate 504 by bolts, and the cutter 505 is set horizontally. An abutment strip 3 is fixedly connected to one side of the inner wall of the mounting box 1. The position of the abutment strip 3 corresponds to that of the cutter 505. If the cutter 505 needs to be replaced, it can be replaced simply by removing the bolts.

[0026] Mounting base 2 506 is fixedly connected to the bottom of the inner wall of one end of mounting box 1. Mounting base 2 506 is located on one side of cutter 505. A horizontally arranged mounting bracket 507 is fixedly connected to the outer wall of one end of mounting base 2 506. Two symmetrically arranged scrapers 508 are hinged to the outside of mounting bracket 507. Two springs 2 509 are fixedly connected to the outer wall of the two scrapers 508 at the ends that are far apart from each other. One end of each of the four springs 2 509 is fixedly connected to mounting bracket 507.

[0027] With the thumb gripping the outer wall of the mounting box 1 and the other two fingers pulling the connecting plate 504, the stress of spring 503 is overcome and it lengthens. The connecting plate 504 is then driven to slide along the limiting rod 502. After the cutter 505 contacts the scraper 508, the pressure applied by spring 509 is overcome, and the scraper 508 rotates and is sleeved on the outside of the mounting bracket 507. Therefore, the cutter 505 can push the scraper 508 to flip outward. The pressure of spring 509 will be applied to the outer wall of the cutter 505 through the scraper 508. With the cooperation of the abutment strip 3, the cutter 505 can complete the cutting work. Then, the restriction of the connecting plate 504 is released, and the cutter 505 will return to its original position. When it passes the scraper 508, the residual adhesive on the surface will be scraped off and concentrated on one side of its blade. Under the action of spring 509, it can be ensured that it can adhere to the surface of the cutter 505, which is conducive to ensuring the cleaning effect.

[0028] like Figure 1 and Figure 2 As shown, a fixing component 4 is installed inside the mounting box 1, and the fixing component 4 is located in the middle of the mounting box 1.

[0029] The fixing component 4 includes a rotating shaft 401 that is rotatably connected to the inner wall of one end of the mounting box 1 via a bearing. The rotating shaft 401 is internally threaded with a plurality of inclined screws 402, and the plurality of screws 402 are distributed at equal intervals.

[0030] The tape roll is placed outside the rotating shaft 401. Then, the screw 402 is driven by the knob, which will rotate and move closer to the tape roll along the rotating shaft 401. Then, the other screws 402 are adjusted repeatedly until they contact the inner wall of the tape roll and stop. At this time, the position of the tape roll will also be fixed, which helps to increase the adaptability of the device.

[0031] like Figure 1 and Figure 2 As shown, a guide roller 2 is rotatably connected to one corner of the inner wall of the mounting box 1 via a bearing. A release film is provided on the inner circumference of the guide roller 2, which can prevent the adhesive part of the double-sided tape from sticking to other parts of the device and will not affect the pulling of the double-sided tape. The double-sided tape can play a temporary positioning role after being cut.

[0032] like Figure 1 and Figure 2 As shown, the bottom outer wall of an extension plate at the bottom of the mounting box 1 is set as an arc surface, which can prevent the extension plate from scratching the double-sided tape and make the movement of the double-sided tape smooth enough.

[0033] This utility model provides a high-viscosity flame-retardant double-sided tape cutting device, the specific working principle of which is as follows:

[0034] When the device is working, the tape roll is placed outside the rotating shaft 401. Then, the screw 402 is driven by the knob, which rotates along the rotating shaft 401 towards the tape roll. The other screws 402 are then adjusted repeatedly until they contact the inner wall of the tape roll and stop. At this point, the position of the tape roll is fixed, which increases the adaptability of the device. Then, one end of the double-sided tape is pulled out, passes through the inside of the guide roller 2, and exits the mounting box 1. Simply pull the mounting box 1 to start pasting. The extension plate at the bottom of the mounting box 1 presses against the top wall of the double-sided tape, ensuring that the double-sided tape adheres tightly to the position to be pasted. Finally, the thumb is held against the outer wall of the mounting box 1, and the other two fingers pull the connecting plate 504. The stress of the spring 503 is overcome and it lengthens. The connecting plate 504 will be driven to slide along the limiting rod 502. After the cutter 505 contacts the scraper 508, the pressure applied by the second spring 509 is overcome, and the scraper 508 rotates and is sleeved outside the mounting bracket 507. Therefore, the cutter 505 can push the scraper 508 to flip outward. The pressure of the second spring 509 will be applied to the outer wall of the cutter 505 through the scraper 508. With the cooperation of the abutment strip 3, the cutter 505 can complete the cutting work. Then, the restriction of the connecting plate 504 is released, and the cutter 505 will return to its original position. When it passes the scraper 508, the adhesive residue on the surface will be scraped off and concentrated on one side of its blade. Under the action of the second spring 509, it can be ensured that it can adhere to the surface of the cutter 505, which is conducive to ensuring the cleaning effect.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
