Description

Technical Field

[0001] This utility model relates to the technical field of film cutting equipment, specifically a vertical composite film slitting machine. Background Technology

[0002] Traditional composite film slitting machines have low cutting efficiency, and the unidirectional pressure results in a long time for the film material to break. Furthermore, the blades are prone to damaging the surface of the film material, causing wrinkles or uneven edges.

[0003] The patent published under authorization announcement number CN207861536U describes a vertical composite film slitting machine. This machine allows for flexible removal of the roll-up roller by disassembling the roll-up roller mounting base, achieving sequential installation and disassembly and improving production efficiency. While the design is reasonable and performs well, it lacks a bidirectional coordinated pressure design, making it impossible to simultaneously position the cutting and film support, thus affecting slitting accuracy. Furthermore, traditional film fixing methods easily lead to localized stress concentration, causing material tearing, and the cutting position adjustment is complex, making it difficult to adapt to different film thicknesses.

[0004] Therefore, in view of this, we have studied and improved the existing shortcomings and proposed a vertical composite film slitting machine. Utility Model Content

[0005] The purpose of this invention is to provide a vertical composite film slitting machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vertical composite film slitting machine, comprising: a platform, a power box, a cutting mechanism and an upper support mechanism, wherein a transverse groove is provided in the middle of the top of the platform, a power box is provided at the top of the platform, and a second electric telescopic rod body is provided inside the power box.

[0007] The upper abutment mechanism is used to accelerate the speed at which the film material breaks;

[0008] The cutting mechanism is used to cut the film material.

[0009] Furthermore, the cutting mechanism includes a pressure column, a cutting head, slices, a film-supporting block, an inner shaft, and an outer bushing. The bottom end of the second electric telescopic rod body is provided with a pressure column, the bottom end of the pressure column is provided with a cutting head, the two sides of the bottom end of the cutting head are provided with slices, the middle of the bottom end of the cutting head is provided with an outer bushing, the bottom end of the outer bushing is provided with an inner shaft, and the bottom end of the inner shaft is provided with a film-supporting block.

[0010] Furthermore, the position of the abutment block is lower than the position of the slice.

[0011] Furthermore, the length of the slice is greater than the length of the abutment block.

[0012] Furthermore, the upper abutment mechanism includes a first electric telescopic rod body, a material placement plate, and a corrugated plate. The first electric telescopic rod body is provided on both sides of the top of the platform. A corrugated plate is provided on one side of the first electric telescopic rod body. A protrusion is provided on one side of the top of the corrugated plate. The thickness of the other side of the top of the corrugated plate is equal to half the depth of the groove in the middle of the platform. A material placement plate is provided at the upper end of the other side of the top of the corrugated plate.

[0013] Furthermore, the protruding part at the top of the corrugated plate has a semi-cylindrical structure.

[0014] Furthermore, the thickness of the portion on the other side of the top of the corrugated plate is less than the thickness of the material placement plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, the slicing mechanism first positions and cuts the film material, and the film-stopping block applies a downward pushing force after contacting the film material through the mechanical telescopic structure of the built-in shaft and the external bushing. This force counteracts the upward force of the convex plate of the upper abutment mechanism pushing the material plate, thereby shortening the film material breakage time and improving the slitting efficiency.

[0017] 2. The semi-cylindrical protrusion of the corrugated plate of this utility model reduces friction with the film material, and the number of film blocks is greater than that of the slices and is evenly distributed, avoiding local stress concentration that could cause wrinkles or tears in the film material; the material placement plate is aligned with the bottom of the cutting head to ensure accurate cutting position and improve slitting quality.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-5 As shown, a vertical composite film slitting machine includes: a platform 1, a power box 3, a cutting mechanism and an upper support mechanism. A transverse groove is provided in the middle of the top of the platform 1. The power box 3 is provided at the top of the platform 1. A second electric telescopic rod body 7 is provided inside the power box 3.

[0026] The upper abutment mechanism is used to accelerate the breaking speed of the film material;

[0027] The cutting mechanism is used to cut the film material.

[0028] The cutting mechanism includes a pressure column 2, a cutting head 4, slices 9, a film-supporting block 12, an internal shaft 10, and an external bushing 11. The pressure column 2 is located at the bottom end of the second electric telescopic rod body 7. The cutting head 4 is located at the bottom end of the pressure column 2. Slices 9 are located on both sides of the bottom end of the cutting head 4. An external bushing 11 is located in the middle of the bottom end of the cutting head 4. The internal shaft 10 is located at the bottom end of the external bushing 11. The film-supporting block 12 is located at the bottom end of the internal shaft 10.

[0029] The rest are provided with slicing blades 9 extending from both sides of the bottom end of the cutting head 4. The slicing blades 9 can cut the film material on the surface of the material plate 6. Since the width of the slicing blades 9 is smaller than the width of the cutting head 4, and the number of slicing blades 9 can be increased, the contact area of ​​the slicing blades 9 with the film material can be increased.

[0030] When the cutting head 4 drives the slice 9 to quickly cut the film material that penetrates the surface of the feeding plate 6, since the position of the abutment block 12 is lower than the position of the slice 9, the abutment block 12 contacts the surface of the film material before the slice 9. The number of abutment blocks 12 is greater than the number of slices 9, so that multiple abutment blocks 12 abut against the surface of the film material.

[0031] Because the built-in shaft 10 and the outer bushing 11 form a mechanical telescopic structure, when the abutting block 12 abuts against the film material on the surface of the material plate 6, the abutting block 12 is forced to move the built-in shaft 10 upward. At this time, the built-in shaft 10 moves upward inside the outer bushing 11. When the built-in shaft 10 is completely overlapped with the outer bushing 11, the abutting block 12 applies a downward pushing force to the film material, so that the slice 9 and the abutting block 12 can quickly cut the film material placed at the bottom of the cutting head 4.

[0032] like Figures 1-5As shown, a vertical composite film slitting machine includes an upper support mechanism comprising a first electric telescopic rod body 5, a material placement plate 6, and a corrugated plate 8. The first electric telescopic rod body 5 is arranged on both sides of the top of the platform 1. A corrugated plate 8 is arranged on one side of the first electric telescopic rod body 5. A protrusion is provided on one side of the top of the corrugated plate 8. The thickness of the other side of the top of the corrugated plate 8 is equal to half the depth of the groove in the middle of the platform 1. A material placement plate 6 is arranged at the upper end of the other side of the top of the corrugated plate 8.

[0033] The rest are as follows: a transverse groove is provided in the middle of the platform 1, and a material plate 6 is placed inside the groove. The surface of the material plate 6 is used to place the film material, and the surface of the material plate 6 is on the same straight line as the bottom surface of the cutter head 4.

[0034] After the first electric telescopic rod body 5 is started, the first electric telescopic rod body 5 pushes the corrugated plate 8 to move between the corrugated plate 8 and the groove between the mounting frame 1. Since there are multiple protrusions on one side of the top of the corrugated plate 8, and these protrusions are semi-cylindrical, when the protrusions move with the corrugated plate 8, the protrusions gradually squeeze into the groove between the mounting plate 6 and the mounting frame 1. At this time, the mounting plate 6 moves upward.

[0035] At this time, the film material on the surface of the feeding plate 6 moves upward under the force. As the slice 9 at the bottom of the cutting head 4 and the film-supporting block 12 move downward, the cutting head 4, slice 9, film-supporting block 12 and the feeding plate 6 form a mutual up-and-down force, thereby accelerating the speed at which the film material at the top of the feeding plate 6 breaks.

[0036] Working principle: When using this vertical composite film slitting machine, first place the film material to be cut at the top center of the platform 1, and place the film material at the top of the material plate 6. Then start the second electric telescopic rod body 7 inside the power box 3. The second electric telescopic rod body 7 drives the pressure column 2 to move downward. The pressure column 2 drives the cutting head 4 to approach the surface of the film material at the top of the material plate 6. At this time, the slices 9 on both sides of the bottom end of the cutting head 4 first position and cut the surface of the film material. The film abutment block 12 at the bottom center of the cutting head 4 abuts against the top of the cut film material. At the same time, the external bushing 11 and the internal shaft 10 make the force transmitted by the film abutment block 12 first transmitted to the surface of the film material, and the surface of the cut film material is subjected to downward force.

[0037] Then start the first electric telescopic rod body 5. The first electric telescopic rod body 5 drives the corrugated plate 8 to move towards the side of the material placement plate 6. When the protruding part at the top of the corrugated plate 8 is gradually inserted into the groove between the material placement plate 6 and the placement frame 1, the material placement plate 6 moves upward and generates an upward force, and the film block 12 and the cutting head 4 and the slice 9 generate a downward force.

[0038] At this time, the surface of the film material on the surface of the material plate 6 is penetrated by the slice 9 at the bottom of the cutter head 4, and the film block 12 quickly pushes out the film material fixed around the bottom of the cutter head 4. In this way, the film material will be cut by the slice 9 and the film block 12. This is the working principle of the vertical composite film slitting machine.

[0039] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
