Description

Technical Field

[0001] This utility model relates to the field of thermal bag production technology, specifically to a cutting device for a thermal bag making machine. Background Technology

[0002] Insulated bags are packaging bags used to hold various foods and keep them warm and fresh. Insulated bags are produced by bag-making machines, which are machines that make various plastic or other material packaging bags. Their processing range includes packaging bags of various sizes, thicknesses and specifications of plastic or other materials, with plastic packaging bags being the main product.

[0003] Because the thermal insulation bag is made of soft material and has a certain degree of elasticity, when the cutting blade in the relevant cutting device cuts the thermal insulation bag, the blade may become dull after long-term use or the thermal insulation bag material is too strong to cut easily. This may cause the part of the thermal insulation bag that contacts the cutting blade to be concave in the direction of force, and the cutting blade cannot effectively cut the thermal insulation bag. This can easily cause the position of the thermal insulation bag to shift, affecting the normal operation of the cross-cutting device. In order to prevent the position of the thermal insulation bag from shifting during the cross-cutting process, pressure plates are often used to press and position the two sides of the thermal insulation bag at the cutting point. After the cross-cutting is completed, the pressure plate moves upward to release the restriction on the thermal insulation bag. When the pressure plate moves upward, the protective pad on the lower side of the pressure plate can easily stick to the thermal insulation, causing the cut thermal insulation bag to move upward, affecting the normal feeding of the thermal insulation bag.

[0004] To address the aforementioned technical problems, this application proposes a cutting device for an insulated bag making machine. Utility Model Content

[0031] As attached Figure 1 and attached Figure 3 As shown, a cutting device for an insulated bag making machine includes a frame 1. The upper front part of the frame 1 is provided with a mounting groove 2. Multiple sets of rollers 3 are installed inside the mounting groove 2. A motor 5 connected to a set of rollers 3 is fixedly installed on the outer side of the frame 1. The upper height of the rollers 3 is higher than the upper height of the frame 1. The insulated bag is located on the upper side of the multiple sets of rollers 3. The two sets of rollers 3 on the front and rear sides are linked by a conveyor belt to transport the insulated bag. The outer side of the rollers 3 is covered with an anti-slip sleeve 4 to prevent the insulated bag from sliding on the outer side of the rollers 3 and affecting the feeding effect.

[0032] Cutting blade 11 moves rapidly laterally to cut the insulation bag material, as shown in the attached image. Figure 1 Appendix Figure 4 and attached Figure 5 As shown, an inverted U-shaped frame 6 is installed on the upper rear side of the platform 1. An electric telescopic rod 7 is installed on the top of the inverted U-shaped frame 6, with the extended end of the electric telescopic rod 7 facing downwards. An installation frame 8 is installed inside the installation frame 8, and a horizontally moving cutting blade 11 is installed inside the installation frame 8. The electric telescopic rod 7 drives the installation frame 8 to move downwards. The lower end of the cutting blade 11 has a sharp structure, which allows the cutting blade 11 to pierce the material in the insulation bag. A horizontal moving track 9 is installed inside the installation frame 8, and a stepping motor is fitted on the outside of the horizontal moving track 9. The moving component 10 has the cutting blade 11 fixedly installed on the lower side of the advancing motor drive component 10. The advancing motor drive component 10 reciprocates on the outside of the horizontal moving track 9. Its structure is the same as that of the printer that drives the print head to move horizontally and reciprocates. The mounting frame 8 has a slide 12 through which the cutting blade 11 passes. The advancing motor drive component 10 drives the cutting blade 11 to move quickly inside the slide 12 to cut the insulation bag material. The upper side of the frame 1 has a knife groove 19 to protect the lower end of the cutting blade 11.

[0033] To prevent the insulation bag material from shifting during the transverse cutting process, please refer to the attached... Figure 4As shown, pressure blocks 13 are installed on the lower side of the mounting frame 8 and on both sides of the slide rail 12. Multiple pressure sensors 15 are installed on the lower side of the pressure blocks 13. A perforated rubber pad 14 is installed on the lower side of the pressure blocks 13, and the rubber pad 14 wraps around the outside of the multiple pressure sensors 15. During the downward movement of the mounting frame 8, the rubber pads 14 on the lower side of the two pressure blocks 13 press on both sides of the material cutting position of the insulation bag, positioning the insulation bag material and detecting the pressure through the pressure sensors 15. When the pressure reaches the set threshold, the signal is transmitted to the control unit on the side wall of the inverted U-shaped frame 6 through the wire. The control unit controls the electric telescopic rod 7 to stop extending and position the pressure block 13 to prevent excessive pressure from damaging the insulation bag material. The initial position of the cutting blade 11 is between the two pressure blocks 13. After the lower end of the cutting blade 11 pierces the insulation bag material vertically downward, it moves laterally to complete the cutting of the insulation bag.

[0034] To prevent the rubber pad on the underside of the pressure block 13 from sticking to the cut insulation bag material, as shown in the attached... Figure 4 and attached Figure 5 As shown, the pressure block 13 has a hollow interior and communicates with the through hole on the rubber pad 14. An air supply assembly communicating with the hollow interior of the pressure block 13 is installed on the mounting frame 8. The air supply assembly includes a diffuser frame 17 and a fan 18. The diffuser frame 17 is fixedly installed on the upper side of the mounting frame 8. The fan 18 is installed on the upper side of the diffuser frame 17 and its air outlet is connected to the diffuser frame 17. A guide pipe 16 connects the diffuser frame 17 and the hollow interior of the pressure block 13. After cutting, when the electric telescopic rod 7 retracts upward, the control unit starts the fan 18. The fan 18 supplies air into the diffuser frame 17 and supplies air into the hollow interiors of the two pressure blocks 13 through the two sets of guide pipes 16, and discharges through the through hole on the rubber pad 14. Through slow exhaust, the insulation bag material is separated from the rubber pad 14, and the cut insulation bag material is fed along the slide groove on the upper side of the frame 1.

[0036] Based on Example 1, to prevent the material position of the insulation bag from shifting during the feeding process, as shown in the attached... Figure 2 and attached Figure 6As shown, two sets of limiting plates 26 are installed on the upper side of the platform 1 and inside the inverted U-shaped frame 6. A distance adjustment assembly that drives the two sets of limiting plates 26 to move synchronously is installed on the lower side of the platform 1. The distance adjustment assembly includes a bidirectional threaded shaft 21 and two sets of moving blocks 22. The lower side of the platform 1 is provided with a second mounting groove 20 communicating with the tool groove 19. The bidirectional threaded shaft 21 is rotatably installed inside the second mounting groove 20. A second motor 24 connected to the end of the bidirectional threaded shaft 21 is fixedly installed on the outer side of the platform 1. The two sets of moving blocks 22 are respectively sleeved on the outer sides of both ends of the bidirectional threaded shaft 21 and communicate with it. Through threaded connection, the distance between the two sets of limiting plates 26 is adjusted in advance according to the width of the insulation bag material.

The two ends of the limiting shaft 23 are fixedly connected to the side wall of the mounting groove 20, and the axis is parallel to the axis of the bidirectional threaded shaft 21. The limiting shaft 23 limits the moving blocks 22 to prevent the moving blocks 22 from rotating with the bidirectional threaded shaft 21. The bidirectional threaded shaft 21 drives the two sets of moving blocks 22 to move closer or further away at the same time.

[0037] A connecting block 25 is installed on the upper side of the moving block 22. The connecting block 25 slides through the knife groove 19 and is connected to the limiting plate 26 at its top to adjust the distance between the two sets of limiting plates 26. The lower side of the limiting plate 26 is in contact with the upper side of the frame 1 to limit the material of the heat preservation bag. A U-shaped groove 27 is provided between the connecting block 25 and the limiting plate 26 to allow the cutting knife 11 to pass through, so as not to affect the lateral reciprocating movement of the cutting knife 11.
