Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive film production, and in particular to a fixing fixture for multi-segment cutting of hot melt adhesive film. Background Technology

[0002] Hot melt adhesive webs, as an important bonding material, are widely used in textiles, clothing, footwear, automotive interiors, and many other fields. In practical applications, it is often necessary to cut rolls of wide hot melt adhesive webs into narrow products of specific widths or to segment and slice them to meet different production needs. Currently, cutting equipment is commonly used for slitting or cutting hot melt adhesive webs. However, existing cutting equipment has some significant drawbacks during operation. First, hot melt adhesive webs are typically soft and have a certain degree of stickiness. When the cutting blade presses down, they are prone to shifting, shrinking, or wrinkling due to stress, resulting in inaccurate cutting paths and uneven cuts, severely impacting cutting quality and product yield. Second, traditional fixing methods often use simple pressure plates or clamps. While these provide some fixation before cutting, they often lack effective dynamic pressing and smoothing mechanisms, especially in the areas on both sides of the cutting line, where the fixing effect is poor. Utility Model Content

[0003] In view of this, the purpose of this utility model is to propose a fixing fixture for multi-segment slicing of hot melt adhesive film, so as to solve the technical problems in the prior art.

[0004] To achieve the above objectives, this utility model provides a fixing fixture for multi-segment slicing of hot melt adhesive film, comprising: The machine platform has clearance slots on it; A pair of support plates are symmetrically fixed on the machine base and located at both ends of the clearance groove. Positioning blocks are slidably installed on the support plates, and a cutting blade is fixed between the two positioning blocks. The drive component, located between the bottom of the positioning block and the machine base, is used to drive the cutting blade to descend and cut. The lead screw is rotatably mounted between two positioning blocks; A pair of movable plates are symmetrically threaded onto the surface of the lead screw. Each movable plate has a guide hole, through which a guide rod is movably inserted and fixed to a positioning block. At least one pressing element is hinged to the bottom of the movable plate; The hinge rod is hinged at one end to the side of the pressing component near the positioning block; At least one groove is provided at the bottom of the movable plate, and a first fixing rod is fixed inside it; The U-shaped block is fitted onto the first fixed rod, and the other end of the hinge rod is hinged to the bottom of the U-shaped block; The first spring is sleeved on the surface of the first fixed rod, and its two ends are respectively fixed to the side wall of the U-shaped block and the side wall of the slide groove.

[0005] Preferably, the driving component includes: A connecting rod is fixed to the bottom of the positioning block, and the lower end of the connecting rod extends to the bottom of the machine through a clearance groove. A connecting plate is fixed between the bottoms of the two connecting rods. A bracket is fixed to the bottom of the machine tool, and an electric push rod is fixed in the middle of the bracket, with the output end of the electric push rod fixed at the middle position of the bottom of the connecting plate.

[0006] Preferably, both ends of the lead screw are provided with threads, and the threads at the left and right ends are arranged in opposite directions.

[0007] Preferably, bearings are provided at both ends of the lead screw, and the inner ring of the bearing is fixedly connected to the surface of the lead screw, and the outer ring of the bearing is fixedly connected to the interior of the adjacent positioning block.

[0008] Preferably, there are two pressing members, which are symmetrically hinged at both ends of the bottom of each movable plate away from the positioning block.

[0009] Preferably, the bottom of the pressing member has a groove, and a push roller is rotatably mounted in the groove.

[0010] Preferably, the fixed fixture further includes two sets of movable slots symmetrically opened on the machine base, with each set of movable slots arranged opposite to each other on both sides of the cutting blade; A second fixed rod is fixed in the movable groove, and a movable block is slidably fitted on the surface of the end of the second fixed rod away from the positioning block. The movable block is located directly below the adjacent push roller. A second spring is fitted onto the other end of the second fixed rod, and both ends are fixed to the side wall of the movable groove and the side wall of the movable block, respectively.

[0011] Preferably, the movable block is made of elastic rubber, and the height of the movable block is flush with the top of the movable groove.

[0012] The beneficial effects of this utility model are as follows: The fixture for multi-segment slicing of hot melt adhesive film, as described in this utility model, utilizes a push roller located at the bottom of the pressing component. This push roller, in conjunction with a hinged rod, a U-shaped block, and a first spring, rolls and contacts the hot melt adhesive film during the deflection of the pressing component. This not only achieves the pressing function but also unfolds and smooths the film material to both sides. Combined with a movable block made of elastic rubber located directly below the push roller, and the movable design of the block under the action of a second spring, this constitutes a highly efficient "rolling-smoothing" action. This action actively eliminates wrinkles that have formed or may form in the film material during feeding or cutting, further ensuring the flatness of the cutting area and thus improving the quality of the final product. The distance between the two moving plates can be easily adjusted by rotating the lead screw, thereby adjusting the position of the pressing parts on both sides. This design allows the fixed fixture to quickly adapt to the cutting needs of hot melt adhesive film of different widths, greatly enhancing the versatility and practicality of the equipment, avoiding the trouble of frequently changing special fixtures for different specifications of products, and improving production efficiency.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0017] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0018] The first aspect of this utility model proposes a fixing fixture for multi-segment slicing of hot melt adhesive film, such as... Figure 1-5 As shown, it includes: Machine 1, on which a clearance groove 101 is provided; A pair of support plates 2 are symmetrically fixed on the machine base 1 and located at both ends of the clearance groove 101. Positioning blocks 3 are slidably installed on the support plates 2, and a cutting blade 4 is fixed between the two positioning blocks 3. The drive component is located between the bottom of the positioning block 3 and the machine base 1, and is used to drive the cutting blade 4 to descend and cut. The lead screw 5 is rotatably mounted between two positioning blocks 3; A pair of movable plates 6 are symmetrically threaded onto the surface of the lead screw 5. The movable plates 6 are provided with guide holes, and the guide rod 7 movably passes through the guide holes and is fixed to the positioning block 3. At least one pressing element 8 is hinged to the bottom of the movable plate 6; The hinge rod 9 is hinged at one end to the side of the pressing member 8 near the positioning block 3. It should be noted that the height of the pressing member 8 is lower than the height of the cutting blade 4. When the cutting blade 4 descends, the pressing member 8 first contacts the hot melt adhesive mesh and positions the hot melt adhesive mesh. At least one groove 601 is provided at the bottom of the movable plate 6, and a first fixing rod 10 is fixed therein; The U-shaped block is fitted onto the first fixed rod 10, and the other end of the hinge rod 9 is hinged to the bottom of the U-shaped block; The first spring 11 is sleeved on the surface of the first fixed rod 10, and its two ends are respectively fixed to the side wall of the U-shaped block and the side wall of the slide groove 601.

[0019] In the multi-segment cutting process of roll-up wide hot melt adhesive film, the hot melt adhesive film is conveyed at equal intervals by an external conveying device. When the drive assembly drives the cutting blade 4 to descend, the pressing part 8 first contacts the hot melt adhesive film and presses it to ensure the stability of the hot melt adhesive film in the multi-segment cutting. As the cutting blade 4 continues to descend, the pressing part 8 is squeezed and deflected, and the U-shaped block at the end of the hinge rod 9 slides on the surface of the first fixed rod 10. At the same time, the first spring 11 is squeezed and generates a reverse force, which acts on the U-shaped block, so that the pressing part 8 at one end of the hinge rod 9 is always in stable contact with the two sides of the hot melt adhesive film. At the same time, the cutting blade 4 descends to cut the hot melt adhesive film. When the drive assembly drives the cutting blade 4 to move upward after cutting, the bottom of the pressing part 8 is released from the pressure, and the first spring 11 returns the pressing part 8 to the initial position for easy reuse. Furthermore, when it is necessary to adjust the distance between the two moving plates 6 to effectively fix hot melt adhesive film of different widths, the moving plates 6 with threads installed on the surface of the screw 5 can be moved relative to each other or in opposite directions under the guidance of the guide rod 7 by manually rotating the screw 5. This allows the fixing fixture to quickly adapt to the cutting requirements of hot melt adhesive film of different widths, greatly enhancing the versatility and practicality of the equipment, avoiding the trouble of frequently changing special fixtures for different specifications of products, and improving production efficiency.

[0020] In this embodiment: the driving component includes: A connecting rod 12 is fixed to the bottom of the positioning block 3. The lower end of the connecting rod 12 extends to the bottom of the machine base 1 through the clearance groove 101. A connecting plate 13 is fixed between the bottoms of the two connecting rods 12. A bracket 14 is fixed to the bottom of the machine base 1. An electric push rod 15 is fixed in the middle of the bracket 14, and the output end of the electric push rod 15 is fixed in the middle position of the bottom of the connecting plate 13. During the cutting process, the output end of the electric push rod 15 drives the connecting plate 13 to descend, which in turn causes the connecting rod 12 at the bottom of the two positioning blocks 3 to move down. This causes the two positioning blocks 3 to drive the cutting blade 4 fixed between them to descend, thus performing the hot melt adhesive film cutting operation.

[0021] In this embodiment, both ends of the lead screw 5 are threaded, and the threads at the left and right ends are arranged in opposite directions. By arranging the threads at the left and right ends of the lead screw 5 in opposite directions, the two moving plates 6 can move relative to or in opposite directions.

[0022] In this embodiment, bearings are provided at both ends of the lead screw 5, and the inner ring of the bearing is fixedly connected to the surface of the lead screw 5, while the outer ring of the bearing is fixedly connected to the interior of the adjacent positioning block 3. It should be noted that a rotating handwheel is fixedly connected to one end of the lead screw 5 to facilitate its rotation.

[0023] In this embodiment, two pressing members 8 are provided, and the two pressing members 8 are symmetrically hinged to both ends of the bottom of each movable plate 6 on the side away from the positioning block 3. It should be noted that by setting two pressing members 8 symmetrically at the bottom of each movable plate 6, both sides of the hot melt adhesive film cutting position can be pressed and fixed simultaneously, thereby further improving the stability of hot melt adhesive film cutting.

[0024] In this embodiment, the bottom of the pressing member 8 has a groove, and a push roller 801 is rotatably mounted in the groove. With the push roller 801 in place, when the pressing member 8 is squeezed and deflected, the push roller 801 at the bottom of the pressing member 8 rolls on the hot melt adhesive web, which unfolds and smooths the film material to both sides, preventing wrinkles in the hot melt adhesive web during cutting and affecting the cutting quality, thereby improving the cutting effect.

[0025] In this embodiment: the fixed fixture also includes two sets of movable slots 102 symmetrically opened on the machine base 1, and each set of movable slots 102 is arranged opposite to each other on both sides of the cutting blade 4; The second fixed rod 16 is fixed in the movable groove 102, and the movable block 17 is slidably fitted on the surface of the second fixed rod 16 away from the positioning block 3. The movable block 17 is located directly below the adjacent push roller 801. A second spring 18 is fitted onto the other end of the second fixed rod 16, and both ends are fixed to the side wall of the movable groove 102 and the side wall of the movable block 17, respectively. It should be noted that since the movable block 17 is located directly below the adjacent push roller 801, as the push roller 801 deflects with the pressing member 8 and rolls in contact with the hot melt adhesive film, the push roller 801 simultaneously presses the hot melt adhesive film onto the surface of the movable block 17. Furthermore, as the push roller 801 rolls, it squeezes and pushes the pressed movable block 17 to move synchronously, thereby further improving the unfolding effect of the hot melt adhesive film.

[0026] In this embodiment, the movable block 17 is made of elastic rubber, and its height is flush with the top of the movable groove 102. Because the movable block 17 is made of elastic rubber, the hard contact is reduced when the push roller 801 presses the hot melt adhesive film, thus reducing the wear caused by the pressing of the hot melt adhesive film.

[0027] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
