[0027] Referring to Figure 1 The utility model provides a cutting film device for cutting the film material on the film material roll, the film material includes the first edge and the second edge of the first angle, the cutting film device includes the bottom platform 1, the bottom platform 1 is arranged at the side of the film material roll close to the film outlet end, is used for carrying the film material, the film material on the film material roll can be stretched out from the film outlet end and is placed on the bottom platform 1, the bottom platform 1 is provided with the positioning assembly 2, is used for positioning the film material, the bottom platform 1 is recessed with the cutter groove 3, the cutter groove 3 is located between the positioning assembly 2 and the film material roll, the cutter groove 3 is provided with the cutter 4, and the cutter 4 can slide in the cutter groove 3, is used for cutting the film material.

[0028] Specifically, the positioning assembly 2 comprises a first stopper 21 and a second stopper 22 arranged at a first angle, for limiting the cutting size, so that the product consistency is good after each cutting, and at the same time, it is not necessary to measure each time, improving the efficiency. When the worker wants to cut the film on the film roll, first pull out the film, and then uncover the protective layer at the bottom of the film, then place the film on the base 1, and abut the first edge with the first stopper 21 and the second edge with the second stopper 22, complete the positioning of the film, at this time the worker can press the intersection of the first edge and the second edge of the film with one hand, and then slide the cutter 4 with the other hand, complete the cutting process of the film, this process only needs one worker to operate, saves time and effort, and the cutter 4 slides in the cutting groove 3 to realize cutting, which can avoid cutting skew and other consequences and thus waste the film.

[0029] It can be understood that the first edge of the film corresponds to the width direction of the film, and the second edge of the film corresponds to the length direction of the film, the first stopper 21 and the second stopper 22 are arranged at a first angle, and then the first edge and the second edge arranged at a first angle on the film are resisted, that is, the length direction and the width direction of the film are quickly positioned, that is, the first stopper 21 and the second stopper 22 form a rigid angle positioning system, which constrains the edge of the film and realizes positioning, compared with the prior art which needs to measure the short side and the long side of the film respectively and then manually aligns and cuts, this way reduces the manual adjustment time and simplifies the positioning steps, which is very convenient.

[0030] Further, the first angle is 90 degrees. The first stopper 21 and the second stopper 22 are vertically arranged on the base 1, and the first edge and the second edge of the film are also vertically arranged, which reduces the positioning difficulty. It needs to be explained here that the worker can first trim the film on the film roll before placing the film on the base 1, trim the free end of the film flat, that is, trim the first edge and the second edge of the film vertically, and then the first stopper 21 and the second stopper 22 arranged vertically can quickly position the film.

[0031] In addition, the cutting groove 3 is arranged on the base 1, and the cutter 4 is arranged in the cutting groove 3 for cutting the film. The cutting groove 3 provides a guide for the sliding path of the cutter 4, and the worker can cut the film by directly sliding the cutter 4 in the cutting groove 3, so that the cutting action does not need to rely on the experience of the worker, which improves the cutting efficiency and reduces the risk of cutting skew. Moreover, the cutting groove 3 is arranged parallel to the first stopper 21, which can ensure that the first edge of the cut film is parallel to the cut edge, and ensure that the cut film is regular.

[0032] Further, the cutter 4 is provided with a cutting edge at both ends along the extension direction of the cutter slot 3, and the cutter 4 can move bidirectionally in the cutter slot 3 to realize bidirectional cutting of the film material, that is, the cutter 4 can cut the film material at any end in the cutter slot 3, without the need for resetting after cutting, and has high cutting efficiency. It can be understood that the length of the cutter slot 3 is greater than the width of the film material, and when the film material is placed on the base table 1, the cutter 4 can be placed on either side of the film material in the width direction, avoiding shielding of the cutter 4 when the film material is placed on the base table 1, and further hindering the cutting process.

[0033] In an embodiment, in order to realize the connection of the first stop piece 21 and the second stop piece 22 with the base table 1, a first connecting hole 211 is arranged on the first stop piece 21, a second connecting hole 221 is arranged on the second stop piece 22, and the film cutting device further comprises a first connecting piece and a second connecting piece, the first connecting piece fixes the first stop piece 21 on the base table 1 by penetrating the first connecting hole 211, and the second connecting piece fixes the second stop piece 22 on the base table 1 by penetrating the second connecting hole 221. Further, in order to improve the strength of the fixing, the first connecting hole 211 and the second connecting hole 221 are each provided with a plurality of connecting holes, and the connecting pieces are also provided with a plurality of connecting pieces.

[0034] Further, the first stop piece 21 is positionally adjustable relative to the cutter slot 3, that is, the first stop piece 21 is positionally adjustable in a direction forming an angle with the cutter slot 3 and is arranged on the base table 1 to change the positioning position of the film material and further change the limited cutting size to adjust the cutting length of the film material. Preferably, the first stop piece 21 can be adjusted in a direction forming a 90-degree angle with the cutter slot 3, so that the adjustment distance is smaller. It is worth noting that during the adjustment process, the first stop piece 21 is always parallel to the cutter slot 3, ensuring that after the adjustment of the first stop piece 21, the cut film material is still regular.

[0035] Alternatively, the base table 1 is provided with an adjustment long hole arranged in a direction forming an angle with the extension direction of the cutter slot 3, and the first connecting piece is slidably arranged in the adjustment long hole to drive the first stop piece 21 to approach or move away from the cutter slot 3. The worker can move the first stop piece 21 to make the first connecting piece move in the adjustment long hole, so that the first stop piece 21 moves on the base table 1 in a direction approaching or moving away from the cutter slot 3, thereby changing the positioning position of the film material and further changing the limited cutting size to adjust the cutting length of the film material. Preferably, the adjustment long hole is arranged in a direction forming a 90-degree angle with the extension direction of the cutter slot 3.

[0036] In another embodiment, in order to realize the connection of the first stop piece 21 and the second stop piece 22 with the base table 1, the first stop piece 21 and the second stop piece 22 can be connected with the base table 1 by magnetic attraction, the material of the first stop piece 21 and the second stop piece 22 is magnet, and the base table is made of steel.

[0037] Further, the magnetic attraction arrangement allows the worker to change the position of the first blocking piece 21 on the base table 1, so that the first blocking piece 21 is close to or away from the cutter slot 3, thereby changing the positioning position of the film material and changing the limited cutting size to adjust the cutting length of the film material.

[0038] It should be noted that the two connection modes (connecting piece connection or magnetic attraction connection) of the first blocking piece 21 and the second blocking piece 22 with the base table 1 described above are two completely parallel technical solutions, both of which have good beneficial effects, and a person skilled in the art can choose flexibly according to actual use requirements.

[0039] Moreover, the base table 1 is provided with a scale mark, and the worker can accurately adjust the position of the first blocking piece 21 on the base table 1 according to the scale mark on the base table 1, thereby accurately determining the cutting length of the film material, and also can accurately adjust the position of the second blocking piece 22 on the base table 1 according to the scale mark on the base table 1, thereby ensuring that the second blocking piece 22 is aligned with the second edge of the film material.

[0040] In order to ensure the safety performance in the cutting process, the cutter 4 is provided with a holding part 41, and when the cutter 4 is placed in the cutter slot 3, the holding part 41 is exposed above the base table 1. Therefore, the sharp part of the cutter 4 for cutting the film material is hidden in the cutter slot 3, and the worker moves the cutter 4 by pinching the holding part 41 with his hand during the cutting process, avoiding the sharp part of the cutter 4 causing safety hazards to the worker. Moreover, a gap should be provided between the bottom end of the holding part 41 of the cutter 4 and the upper surface of the base table 1 for accommodating the film material, so as to avoid the holding part 41 of the cutter 4 being too low to accommodate the film material and thus unable to cut the film material.

[0041] In addition, a limiting groove is arranged in the cutter slot 3, the limiting groove is located on the side wall of the cutter slot 3 and extends along the extension direction of the cutter slot 3, and the side surface of the cutter 4 is provided with a limiting piece, the limiting piece is slidingly arranged in the limiting groove. When the cutter 4 slides in the cutter slot 3, the limiting piece slides in the limiting groove, and the cooperation between the limiting piece and the limiting groove limits the height direction of the cutter 4 in the cutter slot 3, preventing the cutter 4 from falling out of the cutter slot 3.

[0042] In order to further ensure the stability of the film material placed on the base table 1, the film cutting device further comprises a pressing plate, which can be pressed on the film material to press the film material tightly on the base table 1. Since the worker can press the intersection of the first edge and the second edge of the film material with one hand through the pressing plate, and then slide the cutter 4 with the other hand to complete the cutting process of the film material, the pressing plate is provided as an auxiliary tool to press the film material again, avoiding displacement of the film material during cutting.

[0043] A plurality of foot pads 5 are arranged below the base table 1 and used for supporting the base table 1.
