Description

Technical Field

[0001] This utility model relates to the field of thermal insulation bag manufacturing technology, specifically to a longitudinal cutting device for manufacturing micro-foamed nonwoven thermal insulation bags. Background Technology

[0002] Microfoamed nonwoven fabric insulated bags are insulated containers made of microfoamed nonwoven fabric material. Through their special microfoamed structure, they can effectively keep the temperature of food or beverages. At the same time, microfoamed nonwoven fabric insulated bags are reusable and biodegradable, meeting environmental protection requirements. They are becoming increasingly popular in the market and are gradually replacing disposable plastic insulated bags. In the bag-making process of micro-foamed non-woven insulation bags, a longitudinal cutting device is needed to cut the micro-foamed non-woven insulation bags to a suitable size for easy use later. However, in the application of traditional longitudinal cutting devices, the cut insulation bags mostly remain on the platform. Due to the lack of effective unloading measures, the presence of the cut insulation bags on the platform can easily affect the cutting efficiency of subsequent insulation bags.

[0003] Based on this, we propose a longitudinal cutting device for making micro-foamed nonwoven insulation bags to solve the above problems. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this utility model provide a longitudinal cutting device for making micro-foamed nonwoven insulation bags, which solves the technical problem that the presence of insulation bags after slitting on the platform in the prior art can easily affect the subsequent slitting efficiency of insulation bags.

[0005] According to one aspect, at least one embodiment of the present invention provides a longitudinal cutting device for making micro-foamed nonwoven thermal insulation bags, comprising: A support frame, wherein a clearance opening is provided in the middle of one end of the support frame, and a linear slide rail is fixedly connected to the top of one end of the support frame, and a displacement plate is vertically slidably connected to the outer side of the linear slide rail.

[0022] like Figures 1-5 As shown, it illustrates a longitudinal cutting device for making micro-foamed nonwoven thermal insulation bags according to one embodiment of the present invention.

[0023] In some examples, including: Support frame 1, with a clearance opening 2 in the middle of one end of support frame 1, and a linear slide rail 3 fixedly connected to the top of one end of support frame 1, with a displacement plate 4 vertically slidably connected to the outer side of the linear slide rail 3. The cutter 5 is longitudinally fixed to the bottom end of the displacement plate 4. The displacement plate 4 is provided with a guide groove 6. The top of the support frame 1 is provided with a transmission component 7. The transmission component 7 is used to cooperate with the guide groove 6 and the cutter 5 to cut the heat preservation bag. The carrier plate 8 is fixedly connected to the middle of one end of the support frame 1. The two ends of the carrier plate 8 are provided with feeding components 9, which are used to cooperate with the collection box 21 to receive the cut insulation bags.

[0024] For example, such as Figure 3 and Figure 4 As shown, the transmission assembly 7 includes: The central shaft 10 is rotatably connected to the top of one end of the support frame 1. An eccentric plate 11 is fixedly connected to one end of the central shaft 10, and the end of the eccentric plate 11 away from the central shaft 10 is also movably connected to the inside of the guide groove 6. The drive motor 12 is fixedly connected to the top of one end of the support frame 1, and the output end of the drive motor 12 is fixedly connected to the central shaft 10.

[0025] For example, such as Figure 4 As shown, a support hole is provided at the top of one end of the support frame 1, and the central shaft 10 is assembled inside the support hole; More specifically, by setting the support hole, the support frame 1 can have space for the central shaft 10 to pass through, so that the drive motor 12 and the central shaft 10 can be effectively assembled. Furthermore, in order to ensure the smooth rotation of the central shaft 10 on the support hole, a ball bearing is also provided between the support hole and the central shaft 10.

[0026] For example, such as Figure 5 As shown, the end of the eccentric plate 11 away from the central shaft 10 is fixedly connected to a guide rod 13, and the eccentric plate 11 is movably connected to the inside of the guide groove 6 through the guide rod 13.

[0027] More specifically, by setting the guide rod 13, while the guide rod 13 rotates with the eccentric plate 11, the guide rod 13 can slide adaptively inside the guide groove 6 to push the displacement plate 4, causing the displacement plate 4 to push the cutter 5 back to the reset position under the limit of the linear slide rail 3, thereby realizing the longitudinal cutting of the heat preservation bag. For example, such as Figure 5 As shown, the feeding assembly 9 includes: Two upright plates 14 are fixedly connected to the top of both ends of the carrier plate 8. Guide grooves 15 are provided at the bottom of both upright plates 14, and a contact rod 16 is slidably connected between the two guide grooves 15. An electric push rod 17 is fixedly connected to the end of the support frame 1 away from the carrier plate 8. The output end of the electric push rod 17 is fixedly connected to a displacement push plate 18. Both ends of the top of the displacement push plate 18 are vertically provided with waist holes 19, and the two ends of the contact rod 16 are respectively movably connected to the inside of the two waist holes 19.

[0028] For example, such as Figure 5 As shown, since the contact rod 16 will not contact the cut insulation bag when it is displaced at the bend of the guide groove 15, in this embodiment, the end of the carrier plate 8 away from the avoidance opening 2 is U-shaped. Through the structural characteristics of the end of the carrier plate 8 away from the avoidance opening 2, the distance of the contact rod 16 displacement at the bend of the guide groove 15 can be compensated.

[0029] For example, such as Figure 5 As shown, the guide groove 15 is bent upward at one end near the cutter 5, and a wear-resistant layer is provided inside the guide groove 15.

[0030] More specifically, due to the characteristics of the guide groove 15, when the contact rod 16 is moved towards the guide channel 6 under the limit of the guide groove 15, it can move upward along the slope of the guide groove 15, thereby moving away from the carrier plate 8, so that there can be a gap between the contact rod 16 and the carrier plate 8 for the insulation bag to pass through. Furthermore, by setting a wear-resistant layer, the wear of the contact rod 16 when sliding inside the guide groove 15 can be reduced, and the material of the wear-resistant layer can be rubber; For example, such as Figure 1 As shown, a linear slide rod 20 is slidably connected to one end of the support frame 1 near the electric push rod 17, and the end of the linear slide rod 20 near the displacement push plate 18 is also fixedly connected to the displacement push plate 18. More specifically, in conjunction with the connection between the linear slide bar 20 and the displacement push plate 18, the displacement of the displacement push plate 18 can be assisted and guided, thereby balancing the weight at both ends of the displacement push plate 18 and making the displacement of the displacement push plate 18 more stable. Furthermore, to prevent the linear slide bar 20 from detaching from the support frame 1, a limiting piece is fixedly connected to the end of the linear slide bar 20 away from the displacement push plate 18. Working principle: First, the support frame 1 is set on the production line of the thermal insulation bags. The thermal insulation bags to be longitudinally cut, conveyed by the subsequent production line, pass through the material avoidance opening 2 and reach the carrier plate 8, and are then cut as follows: Figure 1As shown, a central box 21 is placed on the support frame 1. At the same time, the drive motor 12 is started. With the connection between the drive motor 12 and the central shaft 10, the eccentric plate 11 can be rotated through the central shaft 10. Since the guide rod 13 is connected inside the guide groove 6, when the guide rod 13 rotates with the eccentric plate 11, the displacement plate 4 can be moved back to its original position under the limit of the linear slide rail 3 by the adaptive movement of the guide rod 13 inside the guide groove 6. When the cutter 5 contacts the heat preservation bag on the carrier plate 8, the heat preservation bag can be longitudinally cut. The longitudinally cut insulation bag will be initially received by the carrier plate 8. Subsequently, after the cutter 5 moves away from the carrier plate 8, the electric push rod 17 is activated to push the displacement push plate 18 to move linearly. Since the contact rod 16 is connected inside the waist hole 19, when the displacement push plate 18 moves linearly, it can push the contact rod 16 to move along the guide groove 15. When the contact rod 16 contacts the insulation bag, as the contact rod 16 continues to move, it can push the insulation bag off the carrier plate 8 and finally receive it through the collection box 21.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
