Description

Technical Field

[0001] This utility model relates to the technical field of soft bag infusion production line equipment, and in particular to a sealing machine cutter punching device. Background Technology

[0002] In the production of soft bag infusions, a 1-outlet 6-filling and sealing machine needs to cut continuous film material into individual bags using a cutter. However, existing technology has the following problems:

[0003] 1. Complex cutter adjustment: Traditional cutters rely on depth adjustment. If the cutter is too deep, it will cause the bag to separate prematurely and roll up when moving in parallel. If it is too shallow, it will cause uneven tear edges. Frequent adjustments are required, which is time-consuming and labor-intensive.

[0004] 2. Low production efficiency: The debugging process leads to wasted time and a high rate of waste bags.

[0005] 3. Simple structure: Most existing cutters are single cutting units, without forming a collaborative cutting structure, making it difficult to accurately control the connection state between bags.

[0006] To address the aforementioned issues, there is an urgent need in this field for a cutting structure that can ensure neat bag cutting without requiring frequent adjustments. Utility Model Content

[0007] This utility model aims to at least partially solve one of the technical problems in the related art.

[0008] Therefore, the purpose of this utility model is to propose a sealing machine cutter punching device. By setting regular holes at both ends of the cutter blade, the 1-3mm connection area between bags can be precisely controlled to form a "close yet distant" state. This eliminates the need for frequent adjustment of the cutter depth, avoids uneven bag rolling and tearing, reduces waste bag rate, requires less cutter adjustment, allows multiple cutters to cut simultaneously, improves work efficiency, and has a stable structure that is easy to maintain.

[0009] To achieve the above objectives, this utility model proposes a sealing machine cutter punching device comprising multiple cutter bodies arranged parallel to each other along the width direction of the film material, each cutter body having holes at both ends of its blade; the spacing between adjacent cutter bodies matches the spacing width between adjacent bags during a single bag making process in the filling and sealing machine, and all the holes of the cutter bodies are aligned one-to-one in the bag conveying direction; the diameter of the holes satisfies that the width of the connection area between adjacent bags after cutting is 1-3mm, forming a slightly separated structure that prevents bag rolling and ensures neat tearing edges.

[0010] This utility model discloses a sealing machine cutter punching device. By setting regular holes at both ends of the cutter blade, it can accurately control the 1-3mm connection area between bags, forming a "near but not far" state. It eliminates the need for frequent adjustment of the cutter depth, avoids bag rolling and uneven tearing, reduces waste bag rate, requires less cutter adjustment, allows multiple cutters to cut simultaneously, improves work efficiency, and has a stable structure that is easy to maintain.

[0011] In addition, the sealing machine cutter punching device proposed in the above application may also have the following additional technical features:

[0012] Specifically, the holes are circular or elliptical and are distributed at equal intervals with the spacing width between adjacent bags along the length direction of the cutter body.

[0013] Specifically, multiple cutter bodies are detachably connected by a fixing frame and synchronously installed at the bag-making station of the filling and sealing machine. The fixing frame is linked with the drive mechanism of the filling and sealing machine to achieve synchronous cutting, and the bottom of the blades of all cutter bodies are located on the same plane.

[0014] Specifically, the blade surface of the cutter body is provided with an anti-stick coating.

[0015] The advantages of this invention compared to existing technologies are as follows:

[0016] (1) By setting regular holes at both ends of the cutter blade, the width of the connection area between the bags after cutting (1-3mm) can be precisely controlled, forming a stable connection state that is "close yet distant". This completely changes the traditional mode that relies on the depth adjustment of the cutter, eliminating the need to frequently adjust the cutting depth of the cutter and greatly reducing the cost of manual intervention.

[0017] (2) The hole design ensures that a uniform weak connection area is retained between the bags after cutting. This avoids the phenomenon of bag rolling caused by complete separation when the bags move in parallel, and allows the waste edges to be easily and completely torn off when tearing the waste edges, so as to achieve neat bag cutting edges and no damage to the edges, and significantly reduce the waste bag rate.

[0018] (3) The reduction in the frequency of cutter adjustments directly shortens the equipment downtime. Multiple cutters are installed synchronously and cut in conjunction with the fixed frame, ensuring precise and consistent cutting actions and significantly improving the continuous operation capability of the soft bag production line.

[0019] (4) The multi-blade body is arranged in parallel along the width of the film material. The blades are installed on the same plane through a detachable fixing frame. It is linked with the filling machine drive mechanism for synchronous cutting, avoiding positional deviation when a single blade operates independently, ensuring cutting accuracy and stability, and facilitating later maintenance and replacement. The structure is simple, reliable, and highly compatible.

[0020] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0021] The above and / or additional aspects and advantages of this utility model will become apparent and readily understood from the following description of the embodiments taken in conjunction with the accompanying drawings, in which:

[0022] Figure 1 This is a perspective view of a sealing machine cutter punching device according to an embodiment of the present invention;

[0023] Figure 2 This is a front view of a sealing machine cutter punching device according to an embodiment of the present invention.

[0024] As shown in the figure: 1. Cutting body; 2. Hole; 11. Blade. Detailed Implementation

[0025] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0026] The following description, in conjunction with the accompanying drawings, describes a sealing machine cutter punching device according to an embodiment of the present invention.

[0027] like Figures 1-2 As shown, a sealing machine cutting and punching device according to an embodiment of the present invention includes a plurality of cutting blade bodies 1 arranged in parallel along the width direction of the film material, and each cutting blade body 1 has holes 2 at both ends of its blade 11.

[0028] In this embodiment, the cutting and punching structure includes multiple cutting blade bodies 1 arranged parallel to each other along the width direction of the membrane material. Each cutting blade body 1 is a long strip-shaped metal blade, and its length direction is consistent with the width direction of the membrane material, i.e., perpendicular to the membrane material conveying direction. Each cutting blade body 1 has a blade 11 at its bottom, and holes 2 are machined at both ends of the blade 11 (i.e., both ends of the cutting blade body along its length direction). The holes 2 penetrate the blade 11 and extend along the membrane material conveying direction (i.e., the width direction of the cutting blade body).

[0029] The spacing between adjacent cutter bodies 1 perfectly matches the interval width between adjacent bags during a single bag making process by the filling and sealing machine (for example, if the interval width between bags is 50mm, then the spacing between adjacent cutter bodies is set to 50mm), ensuring that the position of the cutter body 1 corresponds one-to-one with the interval area of ​​the bag. At the same time, the holes 2 of all cutter bodies 1 are strictly aligned in the bag conveying direction, that is, the holes 2 on the same film conveying path are in the same vertical plane.

[0030] The diameter of hole 2 is set according to the thickness and toughness of the membrane material, ensuring that the width of the connection area between adjacent bags after cutting is 1-3mm. For example, when the membrane material thickness is 0.1mm, the diameter of hole 2 is set to 2mm. During cutting, the membrane material at the hole 2 position is completely cut off, while the blade 11 between holes 2 only cuts into 2 / 3 of the membrane material depth, leaving a 1-3mm incompletely cut connection area. This keeps the adjacent bags in a "partially connected" state—maintaining a slight connection through the connection area while allowing for easy separation in subsequent processes.

[0031] Workflow:

[0032] 1. Membrane material conveying: The continuous membrane material enters the bag making station along the conveying direction (perpendicular to the length direction of the cutter body). The surface of the membrane material is pre-divided into 6 equally spaced bag areas, and the interval between adjacent bags is the area to be cut.

[0033] 2. Cutter positioning: Multiple cutter bodies 1 are arranged in parallel along the width direction of the film material, and the holes 2 at both ends of the blade 11 are aligned with the center position of the interval area of ​​the adjacent bag body to ensure that the holes 2 are aligned one by one in the bag conveying direction.

[0034] 3. Synchronous cutting: The filling machine drive mechanism drives the cutter body 1 downward, and the blade 11 contacts the film material and applies cutting force:

[0035] The membrane material at position 2 was completely cut off due to the blade penetrating the hole structure, forming the initial break point for the separation of the bag body;

[0036] The blade 11 between holes 2 only cuts into the membrane material to a preset depth (not completely cut off), leaving a 1-3mm connection area between adjacent bags.

[0037] 4. Bag Forming: The cut membrane material continues to be conveyed, and the bag body is kept slightly connected through the connecting area to avoid the bag rolling phenomenon caused by complete separation when moving in parallel; in the subsequent waste edge tearing process, because the connecting area is uniform and thin, the waste edge can be easily and completely torn off along the connecting area to ensure that the bag edge is neat and undamaged.

[0038] In one embodiment of this utility model, such as Figures 1-2 As shown, the holes 2 are circular or elliptical and are distributed at equal intervals with the adjacent bag bodies along the length of the cutter body 1.

[0039] It is understood that, in this embodiment, the holes 2 provided on the blade 11 of the cutter body 1 can be circular or elliptical to adapt to the cutting requirements of different film materials. The holes 2 are distributed along the length direction of the cutter body 1 (i.e., the width direction of the film material), and their spacing is strictly equidistant from the spacing width between adjacent bags during a single bag making process by the filling and sealing machine.

[0040] In one embodiment of this utility model, such as Figures 1-2 As shown, multiple cutter bodies 1 are detachably connected by a fixing frame and synchronously installed at the bag-making station of the filling and sealing machine. The fixing frame is linked with the drive mechanism of the filling and sealing machine to achieve synchronous cutting, and the bottom ends of the blades 11 of all cutter bodies 1 are located on the same plane.

[0041] In this embodiment, it is understood that multiple cutter bodies 1 are installed collaboratively via a detachable mounting bracket. The mounting bracket is a metal frame structure with mounting slots (a component of the mounting bracket) along the width direction of the membrane material that match the number of cutter bodies 1. Each cutter body 1 is detachably installed in its corresponding mounting slot using fastening bolts.

[0042] The top of the cutter body 1 is provided with a mounting hole. After the fastening bolt passes through the mounting hole, it is screwed to the side wall of the mounting groove of the fixing frame, which facilitates the individual disassembly and replacement of any cutter body 1 during later maintenance.

[0043] Coplanar adjustment: During installation, adjust the tightness of the fastening bolts to ensure that the bottom of the blade 11 of all cutter bodies 1 is located on the same horizontal plane (error ≤ 0.1mm), so as to avoid the deviation in cutting depth caused by inconsistent blade height.

[0044] Workflow details:

[0045] 1. Installation and debugging phase

[0046] Multiple cutter bodies 1 are respectively embedded into the mounting slots of the fixing frame and initially fixed by fastening bolts;

[0047] Use a level to check whether the bottom of all blades 11 are on the same plane, and fine-tighten the fastening bolts until the coplanarity accuracy is met.

[0048] Install the fixing frame to the bag-making station of the filling and sealing machine using bolts or snap-fit ​​structures, ensuring that the movement direction of the fixing frame is perpendicular to the film conveying direction.

[0049] 2. Bag making and cutting stage

[0050] Membrane material conveying: Continuous membrane material enters the bag making station in a horizontal direction, and the conveying speed is matched with the cutting frequency of the drive mechanism;

[0051] Synchronous downward pressure: After receiving the cutting signal, the drive mechanism drives the fixed frame and the cutter body 1 to move downward synchronously, and the blade 11 contacts the membrane material;

[0052] Collaborative cutting: Since the blades 11 of all the cutter bodies 1 are coplanar and move synchronously, the membrane material at the hole 2 position is cut at the same time, and the cutting depth of the blades in the area between the holes is consistent, forming a connection area with uniform width (1-3mm).

[0053] Reset and Lift: After cutting is completed, the drive mechanism drives the fixed frame and the cutter body 1 to lift synchronously, and the membrane material continues to be transported to the next process.

[0054] 3. Maintenance and Replacement Phase

[0055] When the blade 11 of a certain cutter body 1 is worn, it is not necessary to disassemble the entire fixing frame. Simply loosen the corresponding fastening bolts, take out the old cutter body and replace the new blade, and readjust the coplanar accuracy. This significantly improves maintenance efficiency.

[0056] It should be noted that the filling and sealing machine is an existing device (e.g., the commercially available GF-1200 soft bag filling and sealing machine, or the GF-1200 1-out-6 filling and sealing unit). Its mounting frame and drive mechanism are standard components from the original manufacturer and require no additional design or marking. The following explanation is based on the existing equipment structure:

[0057] Fixing frame: The original metal frame of the filling machine is adopted (such as the bag making station fixing frame of the GF-1200 filling machine, which is the standard configuration when the equipment leaves the factory and has no special marking). Multiple rectangular installation slots are provided along the width of the film material (corresponding to the cutting requirements of 1 out of 6 bags). The size of the slot is perfectly matched with the cutter body 1.

[0058] Drive mechanism: The pneumatic drive system (or servo motor drive system, depending on the equipment model) of the filling machine is used. For example, the GF-1200 filling machine uses a cylinder to drive the fixed frame to move up and down. The drive signal is uniformly output by the equipment PLC control system. It is a known structure of existing equipment and does not require additional labeling.

[0059] In one embodiment of this utility model, such as Figures 1-2 As shown, the blade 11 of the cutter body 1 is provided with an anti-stick coating.

[0060] In this embodiment, the surface of the blade 11 of the cutter body 1 is coated with an anti-stick coating using existing technology. The coating material is preferably polytetrafluoroethylene (PTFE) or molybdenum disulfide (MoS2), with a thickness of 0.01-0.05 mm and an adhesion strength ≥5 N / cm (compliant with GB / T 9286-2021 "Cross-cut Test for Paints and Varnishes"). The anti-stick coating uniformly covers the cutting surface of the blade 11 and the inner wall of the hole 2, forming a low surface energy interface and significantly reducing the adhesion between the film material and the blade.

[0061] Specifically, taking the commercially available GF-1200 1-out-6 soft bag filling and sealing machine as an example, the specific usage process of the cutting and punching structure of this utility model is as follows:

[0062] 1. Membrane material conveying and positioning

[0063] The continuous film material enters the bag-making station of the filling machine along the conveying direction (perpendicular to the length direction of the cutter body 1). The surface of the film material is pre-divided into 6 equidistant bag areas, with a spacing of 50mm between adjacent bags (matching the parameters of the filling machine).

[0064] The filling machine's traction roller (an existing equipment component) conveys the film material at a speed of 5 m / min. The positioning sensor (standard equipment in existing equipment) detects the position of the film material in real time, ensuring that the gap area between adjacent bags is strictly aligned with the hole 2 of the cutter body 1 in the bag conveying direction.

[0065] 2. Preparation for coordinated operation of the cutter body 1

[0066] Multiple cutter bodies 1 are arranged in parallel along the width of the film material by a fixing frame, and the holes 2 at both ends of the blade 11 of each cutter body 1 are aligned with the center of the bag body interval area (a total of 5 interval areas, with a hole spacing of 50mm).

[0067] The fixed frame is bolted to the bag making station of the GF-1200 filling and sealing machine. Its drive interface is rigidly connected to the cylinder of the filling and sealing machine (existing drive mechanism). The bottom ends of the blades 11 of all cutter bodies 1 are located on the same plane after being adjusted by a level (error ≤ 0.05mm).

[0068] 3. Synchronous cutting process

[0069] Signal triggering: When the positioning sensor detects the film material in place, the PLC system of the filling machine sends a cutting command to the drive mechanism, and the cylinder piston rod drives the fixed frame and the cutter body 1 to move downward synchronously (stroke 25mm, speed 0.5m / s).

[0070] Hole cutting and area preservation:

[0071] The hole 2 (2mm in diameter, circular) of the cutter body 1 contacts the membrane material along with the blade 11. The edge of the hole 2 completely cuts the membrane material, forming the initial break point for bag separation (a total of 5 break points, corresponding to 1-out-6-bag intervals).

[0072] The blade 11 between holes 2 only cuts into 2 / 3 of the membrane material depth (0.06mm when the membrane material thickness is 0.1mm), leaving a 1-3mm uncut connection area, so that the adjacent bags are in a "close yet separate" state.

[0073] Cutting force uniformity: Due to the rigid connection of the fixing frame, all cutter bodies 1 apply cutting force (80N) synchronously, ensuring that the width of the connection area of ​​each bag body interval is consistent.

[0074] 4. Bag forming and subsequent processing

[0075] Parallel movement anti-roll bag: The cut film material continues to be conveyed, and the bag body is slightly connected through a 1-3mm connection area to avoid the rolling phenomenon caused by complete separation.

[0076] Neatness of the tear edge: After the membrane material enters the tear edge station, the waste edge is easily torn off along the break point formed by hole 2 because the connection area is weak, and the edge of the bag is undamaged and without residue.

[0077] 5. Equipment reset and maintenance

[0078] After cutting is completed, the drive mechanism drives the fixed frame and the cutter body 1 to reset and lift, waiting for the next cycle signal.

[0079] When the blade 11 of a certain cutter body is worn, loosen the corresponding fastening bolt, replace the new blade and adjust the coplanar accuracy. The maintenance time for a single maintenance is ≤10 minutes.

[0080] In summary, the sealing machine cutter punching device of this utility model, by setting regular holes at both ends of the cutter blade, precisely controls the 1-3mm connection area between bags, forming a "near but not far" state. It eliminates the need for frequent adjustment of the cutter depth, avoids uneven bag rolling and tearing, reduces waste bag rate, requires less cutter adjustment, allows multiple cutters to cut simultaneously, improves work efficiency, and has a stable structure that is easy to maintain.
