[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] The utility model provides a technical solution:
[0028] See also Figures 1 to 6 , an automatic double-sided tape cutting mechanism, comprising a cutting table 1 and a feeding wheel 2 rotatably arranged on the upper side of the cutting table 1, an adjusting component 3 is arranged on the upper side of the cutting table 1, and the adjusting component 3 includes a first screw drive unit 31 arranged inside the upper side of the cutting table 1;
[0029] A slider 32 is sleeved on the outer side of the outer side of the first screw drive unit 31, and the slider 32 is slidably connected to the upper side of the cutting table 1. A control box 33 is fixedly connected to the upper side of the cutting table 1. A slide groove 34 is provided on the front and the lower side of the control box 33. The slider 32 is slidably connected in the slide groove 34 on the lower side of the control box 33. A movable disk 35 is slidably connected to the inside of the control box 33. A movable disk 36 is slidably connected to the inside of the control box 33. A second screw drive unit 37 is clamped on the right side of the control box 33. The second screw drive unit 37 passes through the movable disk 36 and the movable disk 35. A first return spring 38 is fixedly connected to the right side of the movable disk 35, and the other end of the first return spring 38 is fixedly connected to the left side of the movable disk 36.
[0030] The first screw drive unit 31 is composed of a drive motor, a screw and a screw nut. The slider 32 is sleeved on the outside of the screw nut. The second screw drive unit 37 is composed of a drive motor and a screw.
[0031] A clamping assembly 39 is provided on the front of the control box 33, and the clamping assembly 39 includes a connecting plate 391 slidably connected to the inside of the slide groove 34 opened on the front of the control box 33. A scale line 394 is opened on the front of the cutting table 1, and one side of the back of the connecting plate 391 is fixedly connected to the outer side of the movable disk 36.
[0032] A clamping plate 392 is slidably connected inside the connecting plate 391 . Two bolts 393 are threadedly connected to the upper side of the connecting plate 391 . Both bolts 393 pass through the connecting plate 391 and penetrate the clamping plate 392 .
[0033] A reset component 4 is provided inside the control box 33 .
[0034] By adopting the above technical solution, first, the wound double-sided tape is installed inside the feeding wheel 2, and then one end of the double-sided tape is passed through the cutting tool above the cutting table 1 and placed on the upper side of the connecting plate 391, and then the two bolts 393 are screwed to make the clamping plate 392 move downward, and finally the double-sided tape is clamped. After the double-sided tape is fixed, the driving motor inside the first screw drive unit 31 is started to drive the screw to rotate, so that the screw nut drives the slider 32 to move outside the screw, and after the slider 32 slides in the slide groove 34 located below the control box 33, it will drive the moving disk 35 to move inside the control box 33, and the moving distance of the moving disk 35 can be controlled according to the scale line 394. After the position of the moving disk 35 is determined, the first screw drive unit 31 stops running, and then the second screw drive unit is started. The driving motor inside 37 drives the screw rod to rotate, so that the movable plate 35 gradually moves closer to the movable plate 35, and drives the connecting plate 391 to slide in the slide groove 34 in front of the control box 33. Then, the connecting plate 391 moves, and the double-sided tape locked in the connecting plate 391 by the clamping plate 392 will also be pulled, and finally the double-sided tape is cut by the cutting tool above the cutting table 1. After the movable plate 36 contacts the structure inside the reset component 4, it is reset by the first reset spring 38. At this time, the second screw rod driving unit 37 will continue to drive the movable plate 36 to move. Since the distance between the movable plate 36 and the movable plate 35 is adjustable, after the movable plate 35 is adjusted, the length of the double-sided tape cut each time will be the same, avoiding repeated measurements of the double-sided tape before cutting, thereby ensuring the cutting efficiency of the double-sided tape and improving the subsequent work efficiency.
[0035] Specifically, Figure 5 and Figure 6 As shown, the reset component 4 includes two first magnetic blocks 41 fixedly connected to the right side of the movable disk 35, a movable groove 42 is opened inside the movable disk 36, and two movable blocks 45 are slidably connected inside the movable groove 42. One side of the opposite surfaces of the two movable blocks 45 are threadedly connected to the outside of the second screw drive unit 37.
[0036] Two second return springs 44 are fixedly connected to the left side of the inner part of the movable groove 42, and the other ends of the two second return springs 44 are fixedly connected to the second magnetic blocks 43. The two first magnetic blocks 41 are magnetically attracted to the two second magnetic blocks 43 respectively. After the two second magnetic blocks 43 move, they are respectively inserted into the grooves on the left sides of the two movable blocks 45.
[0037] Two third return springs 46 are fixedly connected to the side away from each other of the two moving blocks 45, and the other ends of the two third return springs 46 are fixedly connected to the same pressure block 48, and the other side of the pressure block 48 is fixedly connected to two tension springs 47, and the four tension springs 47 are all fixedly connected to the inner cavity of the movable groove 42.
[0038] Two extrusion blocks 49 are fixedly connected to the right side of the control box 33 . The two extrusion blocks 49 are inserted into the right side of the movable disk 36 after the movable disk 36 moves. The two extrusion blocks 49 are respectively in extrusion contact with the inclined surfaces of the two pressure blocks 48 .
[0039] By adopting the above technical solution, firstly, during the movement of the movable disk 35, the two movable blocks 45 inside the movable groove 42 will always be threadedly connected with the screw rod inside the second screw drive unit 37, so that the movable block 45 will drive the movable disk 36 to move closer to the movable disk 35. When the movable disk 36 contacts the first magnetic block 41 on the right side of the movable disk 35, the two second magnetic blocks 43 inside the movable groove 42 will be adsorbed, so that the second magnetic block 43 is separated from the movable block 45. At this time, the tension spring 47 will pull the pressure block 48, the third return spring 46 and the movable block 45, so that the movable block 45 is retracted into the movable groove 42. After the movable block 45 is separated from the screw rod inside the second screw drive unit 37, the first return spring 38 will push the movable disk 36, so that the movable disk 36 moves toward the extrusion block 49. At this time, the second magnetic block 43 is lost. After the attraction from the first magnetic block 41 is removed, it will be pushed by the second return spring 44. When the extrusion block 49 enters the movable disk 36 and contacts the pressure block 48, the pressure block 48 will be pushed by the extrusion block 49, so that the pressure block 48 pushes the third return spring 46 and the moving block 45, and gradually approaches the screw inside the second screw drive unit 37. When the groove on one side of the moving block 45 moves to correspond to the second magnetic block 43 again, the second magnetic block 43 will enter the groove again and lock the moving block 45. At this time, the screw inside the second screw drive unit 37 will also be threadedly connected to the moving block 45 again. Since the movable disk 36 will be pushed away after being fitted with the first magnetic block 41 on the side of the movable disk 35, the double-sided tape can be cut and the next cutting operation can be carried out. The cutting length is guaranteed to be the same as the previous time, so that the cutting efficiency of the double-sided tape is further improved.
[0040] Working principle: First, tighten the two bolts 393 to make the clamping plate 392 move downward and clamp the double-sided tape inside the connecting plate 391, then start the first screw drive unit 31 to adjust the position of the slider 32, so that the slider 32 drives the movable disk 35 to move inside the control box 33, at this time, the position of the first magnetic block 41 will also be adjusted accordingly, and observed according to the scale line 394, start the second screw drive unit 37 to drive the movable block 45 to move, so that the movable block 45 drives the movable disk 36 to gradually move closer to the movable disk 35, at this time the double-sided tape will also be pulled, and finally the double-sided tape will be cut by the cutting tool above the cutting table 1, when the movable disk 36 contacts the first magnetic block 41 on the right side of the movable disk 35, it will press the inside of the movable groove 42 The two second magnetic blocks 43 are adsorbed so that the second magnetic block 43 is separated from the moving block 45. At this time, the tension spring 47 will pull the pressure block 48, the third return spring 46 and the moving block 45, and retract into the movable groove 42. At this time, the moving block 45 is separated from the screw inside the second screw drive unit 37. The first return spring 38 will push the movable disk 36, so that the movable disk 36 moves toward the extrusion block 49, and the second magnetic block 43 will be pushed by the second return spring 44. After the extrusion block 49 contacts the pressure block 48, the pressure block 48 pushes the third return spring 46 and the moving block 45, and gradually approaches the screw inside the second screw drive unit 37. At this time, the screw inside the second screw drive unit 37 will also be threadedly connected to the moving block 45 again.
[0041] Among them, the double-sided tape adopts a blank structure with protective paper / release paper on both sides. Through this structure, the sticky surface of the double-sided tape will not adhere to the parts of the cutting mechanism during processes such as clamping and pulling, ensuring the smooth transportation of the double-sided tape and the normal operation of the cutting mechanism.
[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
