Description

Technical Field

[0001] This utility model relates to the technical field of sealing equipment, specifically to a film cutter for a fully automatic sealing machine. Background Technology

[0002] In fields such as biomedical testing, food packaging, and industrial sealing, fully automated sealing machines achieve precise sealing of films through heat pressing or bonding. The film cutter, as its core component, plays a crucial role in cutting the sealing film material to a fixed length.

[0003] In the existing technology, there are two main structural designs for film cutting knives: one is an integral casting structure, in which the blade body and the support frame are integrally machined; the other is a split structure with two supports, in which the two ends of the blade are connected to the drive mechanism through fixed seats.

[0004] The aforementioned structural design has significant technical flaws: when the cutting edge of the film cutter wears down or is accidentally damaged, the one-piece structure requires the entire blade assembly to be scrapped and replaced, resulting in a huge waste of material resources; while the two-end split structure allows for partial replacement, it is limited to the fixed components at both ends of the blade, and cannot provide targeted repair for deformation or breakage in the middle of the blade. This non-modular design leads to high equipment maintenance costs, and the frequent replacement of the entire unit severely affects the working efficiency of the sealing machine.

[0005] To address this technical bottleneck, there is an urgent need in the field for a modular cutting blade structure that enables precise replacement of faulty components through the independent design of functional units, thereby reducing the overall lifecycle cost of the equipment while ensuring cutting accuracy. Utility Model Content

[0006] In view of this, the present invention provides a film cutter for a fully automatic sealing machine. The present invention can disassemble the film cutter as a whole and replace or disassemble any of its parts, so that the cutting accuracy of the film cutter can be guaranteed by regularly replacing and maintaining the parts.

[0007] To solve the above-mentioned technical problems, this utility model provides a film cutter for a fully automatic sealing machine, including a bracket, which is detachably fixed on the sealing machine to provide support for the sealing cutter as a whole, and facilitates the disassembly of the bracket as a whole.

[0008] The sliding blade has a groove inside the bracket, which is connected to the end of the bracket. The sliding blade slides in the groove, and the bottom of the sliding blade is designed to be inclined, which allows for more precise cutting of materials.

[0009] The fixed blade is located at the edge of the groove on the support. The material is located between the fixed blade and the sliding blade. When the sliding blade slides, it can cut the material together with the fixed blade.

[0010] The telescopic component is fixed in the slide groove and provides support for the sliding blade. After the sliding blade slides, it pushes the sliding blade to reset. The telescopic component is detachably fixed on the bracket, and the detachability of the telescopic component makes it easy to disassemble the sliding blade.

[0011] The telescopic component includes two guide rods fixed in the slide groove. The axial direction of the guide rods is consistent with the sliding direction of the sliding blade. The end of the guide rod is provided with a limiting rod through a threaded connection. The limiting rod and the guide rod are located on the same axis. The limiting rod has a T-shaped structure. The end of the limiting rod with a smaller cross section is connected to the guide rod. The sliding blade is slidably sleeved between the two limiting rods. Each limiting rod is sleeved with a thrust spring. The spring is used to push the sliding blade away from the support.

[0012] The end of the limiting rod is provided with a force-applying part, which is a plum blossom groove set at the end of the limiting rod.

[0013] A clearance hole is provided through the sliding blade. A limiting rod is inserted into the clearance hole and connected to the sliding blade. A movable block is slidably provided in the clearance hole. The movable block can slide in the clearance hole. Both the movable block and the clearance hole are T-shaped structures. The movable block will not fall out of the clearance hole. A movable hole is also provided through the clearance hole. The limiting rod is located in the movable hole and slidably connected to the movable block. A spring is located in the movable hole.

[0014] The slide is installed through the bracket, and the side of the bracket away from the sliding blade is also provided with a storage slot. The storage slot is connected to the slide and to both ends of the bracket. A connecting plate is provided inside the storage slot, and the guide rod is fixed to the connecting plate.

[0015] Limiting strips are connected between the two ends of the sliding blade. A storage space is formed between the limiting strips and the sliding blade. The material is placed in the storage space for cutting. The storage space is used to guide and limit the material.

[0016] The bracket includes two fixing blocks, which are arranged symmetrically and form a groove between them. The fixing blade is fixed between the two fixing blocks by bolts, which also facilitates the disassembly of the fixing blade.

[0017] The corresponding film cutting knife also has a detachable base on the frame, and the base has a slide. Both the slide and the bottom of the fixing block have a T-shaped structure, so the fixing block will not fall off from the slide.

[0018] The base is equipped with clamping parts on both sides by bolts, and the ends of the two clamping parts can clamp the two ends of the bracket.

[0019] The clamping components are located at both ends of the storage slot, which allows for the pre-positioning of the limiting plate.

[0020] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0021] 1. Precise modular maintenance reduces total lifecycle costs:

[0022] The bracket adopts a detachable fixing structure, and the sliding blade, fixed blade, and telescopic component are all independent replaceable units. When the cutting edge wears or a component is damaged, only the faulty module (such as the sliding blade or spring assembly) needs to be replaced, without scrapping the entire blade body, significantly reducing material waste and equipment downtime.

[0023] The fixed blade is fixed between two fixed blocks by bolts, while the sliding blade is independently assembled with the telescopic component through a slide groove. The decoupling design of each functional module shortens the maintenance operation time.

[0024] 2. Dual-guided reset mechanism to ensure cutting accuracy:

[0025] The coaxial layout of the guide rod and limit rod in the telescopic component, combined with the elastic reset function of the thrust spring, ensures that the sliding blade automatically and accurately returns to its original position after cutting, avoiding cutting errors caused by blade offset.

[0026] 3. Quick-assembly and disassembly of the base structure improves equipment adaptability:

[0027] The base adopts a combination design of T-shaped slide rail and clamping components. The bracket can be quickly positioned and installed through the slide rail. The pre-tightening force of the clamping components on both ends of the bracket is adjustable, which can adapt to the installation requirements of sealing machines of different specifications and shorten the changeover time.

[0028] 4. Extend the service life of core components:

[0029] The thrust spring is built into the movable hole to avoid direct contact with the membrane material, reducing the risk of corrosion and wear; the plum blossom groove design at the end of the limit rod makes it easy to manually adjust the spring preload, extending the overall service life of the telescopic component.

[0030] 5. Improved operational safety and efficiency:

[0031] The inclined blade design at the bottom of the sliding blade reduces cutting resistance, and combined with the stable support of the fixed blade, the time for a single cutting operation is shortened, while reducing the equipment failure rate caused by blade jamming.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0041] This embodiment provides a film cutter for a fully automatic sealing machine, such as... Figure 1-3 As shown: It includes a bracket 10, which is detachably fixed on the sealing machine to provide support for the sealing knife as a whole. A fixed blade 12 is fixedly mounted on the bracket 10, and a sliding groove 11 is formed on the bracket 10. The sliding groove 11 is located on the side of the fixed blade 12. A sliding blade 14 is slidably mounted in the sliding groove 11. The sliding blade 14 can slide towards the fixed blade 12 in the sliding groove 11. By placing the material between the fixed blade 12 and the sliding blade 14 and then moving the sliding blade 14, the material can be cut.

[0042] The slide groove 11 is also provided with a telescopic member 20. The end of the telescopic member 20 provides support for the sliding blade 14 and can be used to automatically push the sliding blade 14 to reset after it moves.

[0043] Specifically, the telescopic component 20 is a detachable structure, such as... Figure 2 , 3As shown: The telescopic component 20 consists of two guide rods 32 fixed in the slide groove 11. The axial direction of the guide rods 32 is consistent with the sliding direction of the sliding blade 14. The end of the guide rod 32 away from the bracket 10 is also coaxially connected to a limiting rod 21 through a threaded connection. The limiting rod 21 has a T-shaped structure. The end of the limiting rod 21 with a smaller cross section is connected to the end of the guide rod 32. The sliding blade 14 is provided with a clearance hole 24. The limiting rod 21 passes through the clearance hole 24 and is slidably connected to the sliding blade 14. A spring 22 is also sleeved on the limiting rod 21. The spring 22 is a thrust spring 22 used to always push the sliding blade 14 toward the end of the limiting rod 21 with a larger cross section.

[0044] The end of the limiting rod 21 is also provided with a force-applying part 23, which is a plum blossom-shaped groove provided at the end of the limiting rod 21. This groove facilitates the rotation of the limiting rod 21. The force-applying part 23 can also be provided with other structures that facilitate the rotation of the limiting rod 21. That is, when it is necessary to maintain the spring 22 or the sliding blade 14, the limiting rod 21 can be removed by unscrewing it from the guide rod 32, and then the spring 22 and the sliding blade 14 can be removed for maintenance or replacement.

[0045] Furthermore, a movable block 25 is slidably provided inside the clearance hole 24, such as... Figure 2 , 3 As shown: Both the clearance hole 24 and the movable block 25 are T-shaped structures, which can prevent the movable block 25 from falling out of the clearance hole 24. The movable block 25 is also provided with a movable hole 26, which is T-shaped. The limiting rod 21 passes through the movable hole 26 and is slidably connected to the movable block 25. The end of the spring 22 is located inside the movable hole 26. Thus, the clearance hole 24 and the movable block 25 can provide clearance space for the end of the spring 22. Rotating the limiting rod 21 can indirectly adjust the thrust strength of the spring 22.

[0046] Specifically, the slide groove 11 is installed through the support 10, and the support 10 is also provided with a storage groove 30 at the end away from the sliding blade 14. The two ends of the storage groove 30 are connected to the two sides of the support 10, and the storage groove 30 is connected to the slide groove 11. The storage groove 30 is used to place the limiting plate 31, and the two guide rods 32 are fixed on the limiting plate 31, so that the film cutting knife structure can be further disassembled.

[0047] Preferably, the bracket 10 includes two fixing blocks 13, which are symmetrically arranged (correspondingly, the storage slot 30 is disposed through the end of the fixing block 13). Figure 1 , 3 As shown: A groove 11 is formed between the two fixing blocks 13. The two ends of the fixing blade 12 are fixed to the fixing blocks 13 by bolts. The fixing blade 12 can be disassembled by removing the bolts, so that the fixing blade 12 can be maintained or replaced.

[0048] Furthermore, the sliding blade 14 has a concave structure, meaning that the sliding blade 14 has an opening, such as... Figure 1 , 2 As shown in Figure 3: the open side faces the fixed blade 12 and the sliding blade 14 is connected to the two ends by a limiting strip 15. The limiting strip 15 is located in the open side of the sliding blade 14 and forms a storage space between the limiting strip 15 and the sliding blade 14. The material is cut by the sliding blade 14 in the storage space during operation.

[0049] The corresponding cutting knife also has a detachable base 40 on the frame. The base 40 has a slide rail 41. The bottom of the slide rail 41 and the fixing block 13 are both T-shaped, so that the bracket 10 can be slidably installed on the base 40 and the bracket 10 will not fall off the base 40. The bracket 10 also has two clamping parts 42 corresponding to the base 40. The clamping parts 42 are located on both sides of the bracket 10 and are fixed to the base 40 by bolts, so as to achieve the purpose of fixing the bracket 10. The clamping parts 42 are located in the middle of the fixing plate, that is, the clamping parts 42 can pre-position the position of the limiting plate 31 on both sides of the storage slot 30, which is convenient for the subsequent installation of the limiting rod 21 and the spring 22.

[0050] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0051] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
