[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.
[0022] Figures 1 to 5 The first embodiment of the utility model is shown.
[0023] As Figure 1 and Figure 2 shown, the first embodiment of the utility model provides a film cutting structure, comprising:
[0024] The cutting operation unit 1 comprises a sliding block 11 and a cutting blade 12 fixedly connected with the sliding block 11.
[0025] As Figures 3-4 shown, the cutting sliding rail unit 2 comprises an upper-end-opened cutting sliding groove 21 and a sliding rail mounting clamp 22 fixedly connected with the lower end of the cutting sliding groove 21.
[0026] The sliding block 11 is accommodated in the cutting sliding groove 21 and can slide along the cutting sliding groove 21.
[0027] As Figure 4 shown, the sliding rail mounting clamp 22 comprises symmetrically arranged first clamping pieces 221 and second clamping pieces 222, one end of the first clamping pieces 221 and the second clamping pieces 222 is respectively fixedly connected with the cutting sliding groove 21, parallelly extends to the middle part, narrows to form a long and narrow clamping gap, and is separated to both sides at the opposite end to form a flared shape.
[0028] The lower end of the sliding rail mounting clamp 22 in the first embodiment of the utility model is designed as a flared type, plays a guiding role, and can quickly clamp the cutting sliding rail unit 2 on a vertical plane; the long and narrow clamping gap in the middle part of the sliding rail mounting clamp 22 is clamped on both sides of the vertical plane to form two opposite clamping surfaces, and compared with the conventional mounting structure, the mounting structure of the embodiment is more stable and will not cause deviation of the working circuit of the cutting operation unit 1 due to bumping, vibration and the like. As a preferred, the sliding rail mounting clamp 22 can be selected from an elastic material with large rigidity to increase the clamping force of the clamping surface.
[0029] Further, as Figure 1 and Figure 4 shown, the cutting sliding groove 21 is in the shape of an isosceles trapezoid with the long side downward, and the cross section of the sliding block 11 is matched with the cutting sliding groove 21.
[0030] The isosceles trapezoidal section size of the cutting sliding groove 21 of the first embodiment of the utility model is matched with the sliding block 11, so that the sliding block 11 can smoothly slide back and forth along the length direction of the cutting sliding groove 21; because of the design of the long side downward, the contact surface of the two waists of the trapezoid completely limits the up and down movement of the sliding block 11; in the sliding process, because the two are closely fitted, the shaking of the sliding block in the sliding rail can be effectively avoided, and the cooperation tolerance between them is small, so as to ensure the stability and accuracy of the sliding block when sliding.
[0031] Further, as shown in Figure 2 The bottom surface of the sliding block 11 is provided with a chamfer 13 at the intersection with the side surface.
[0032] By setting the chamfer 13, the sliding of the sliding block 11 in the cutting sliding groove 21 is smoother, and the jamming is eliminated.
[0033] Further, as shown in Figure 1 And Figure 2 The cutting blade 12 is a double-sided blade.
[0034] By setting the double-sided blade, the cutting operation unit 1 can cut during the reciprocating sliding process in the cutting sliding rail unit 2, and the work efficiency is improved.
[0035] Further, as shown in Figure 4 The upper end opening of the cutting sliding groove 21 is bent to the two sides to form a first adsorption surface 211 and a second adsorption surface 212, and an electrostatic adsorption layer is arranged on the upper surfaces of the first adsorption surface 211 and the second adsorption surface 212.
[0036] By setting the electrostatic adsorption layer, after the film is cut, the films on the two sides of the cutting line are respectively adsorbed on the first adsorption surface 211 and the second adsorption surface 212, so that the self-adhesion of the film is avoided, and the next process can be quickly connected.
[0037] Further, as shown in Figure 5 The cutting sliding rail unit 2 comprises a limiting mechanism 23; the limiting mechanism 23 comprises a first limiting device 231 capable of elastic contraction and a second limiting device 232 incapable of elastic contraction.
[0038] By setting the limiting mechanism 23, the cutting operation unit 1 can be prevented from separating from the cutting sliding rail unit 2; when the work is paused or moved for a short distance, the cutting operation unit 1 is limited between the first limiting device 231 and the second limiting device 232.
[0039] Further, the second limiting device 232 is at least two, arranged on the bottom surface of the cutting chute 21, near the two ends; the first limiting device 231 is at least two, arranged corresponding to the second limiting device 232; the first limiting device 231 and the adjacent second limiting device 232 form the limiting area of the cutting operation unit 1.
[0040] Further, the bottom surface of the cutting chute 21 is provided with mounting holes, and the first limiting device 231 and the second limiting device 232 are mounted in the mounting holes.
[0041] The second limiting device 232 is arranged at the two ends of the cutting chute 21 and fixedly mounted in the mounting hole, at least partially protruding from the bottom surface of the cutting chute 21, and the protruding part cannot be elastically retracted; the first limiting device 231 is arranged opposite to the second limiting device 232, and the distance between the two can just accommodate the cutting operation unit 1; the first limiting device 231 is fixedly mounted in the mounting hole and can only elastically retract part of the protrusion from the bottom surface of the cutting chute 21.
[0042] In operation, when the cutting operation unit 1 slides through the first limiting device 231, the first limiting device 231 can be retracted part is compressed by the chamfer 13 and the bottom surface of the sliding block 11, and the first limiting device 231 can be retracted part is retracted below the bottom surface of the cutting chute 21 under the action of pressure, and the friction force acting on the sliding block 11 increases and the speed slows down. After the rear end of the sliding block 11 slides through the first limiting device 231, the first limiting device 231 can be retracted part is elastically raised, and the front end of the sliding block 11 contacts the second limiting device and stops. The cutting operation unit 1 stays between the first limiting device 231 and the second limiting device 232.
[0043] The utility model also has a second embodiment. The second embodiment is basically the same as the first embodiment, and the difference is only that:
[0044] The cutting blade 12 comprises a first cutting blade and a second cutting blade, and the cutting edges of the first cutting blade and the second cutting blade are arranged in opposite directions.
[0045] Further, the utility model also provides a film cutting device, and the film cutting device comprises any one of the film cutting structures.
[0046] The equal leg trapezoidal section size of the cutting sliding groove 21 and the sliding block 11 is matched, so that the sliding block 11 can stably slide back and forth along the length direction of the cutting sliding groove 21; because of the design of the long side downward, the contact surface of the two legs of the trapezoid completely limits the up-down movement of the sliding block 11; in the sliding process, because the two are closely fitted, the shaking of the sliding block in the sliding rail can be effectively avoided, and the cooperation tolerance between them is small, so as to ensure the stability and accuracy of the sliding block when sliding.
[0047] The thin film cutting structure provided by the utility model has the advantages that the lower end of the sliding rail mounting clamp 22 is designed as a flared type, so that the installation is more convenient; the long and narrow gap in the middle of the sliding rail mounting clamp 22 ensures that the installation structure of the utility model is more stable; the cross section of the cutting sliding groove 21 and the sliding block 11 adopts an equal leg trapezoidal design, so that the up-down movement of the sliding block 11 is completely limited, and the stable operation of the cutter is ensured.
