Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, specifically to a sealing device for instant noodle packaging. Background Technology

[0002] Currently, most of the sealing equipment available on the market for instant noodle packaging can perform the basic sealing function of instant noodle packaging bags. By heating and pressurizing, the sealing edge of the packaging bag achieves a sealing effect, thereby completing the packaging operation of instant noodles.

[0003] In existing sealing equipment workflows, there is usually a gap between sealing and cutting operations. Most cutting modules use an intermittent cutting method, meaning that the cutting mechanism only starts and cuts the bags after sealing a set of packaging bags. After cutting, the cutting mechanism resets, and the cycle of sealing and cutting the next set of packaging bags begins. This intermittent operation mode prevents the sealing and cutting processes from forming a continuous workflow. A significant amount of ineffective work time is generated during the starting, resetting, and waiting periods for sealing to complete, severely impacting the smoothness and continuity of the overall packaging operation.

[0004] Specifically, the shortcomings of existing slitting modules are mainly reflected in the following aspects: First, the coordination between slitting and sealing actions is poor, and the working rhythm between the two is difficult to match precisely. This easily leads to problems such as slitting lagging behind sealing or slitting too early, resulting in incomplete packaging and increasing the probability of producing defective products. Second, the intermittent slitting method makes it impossible for the production line to achieve uniform and continuous operation. The equipment is frequently in an alternating state of "start-run-stop," which not only reduces the packaging workload per unit time but also aggravates the wear and tear of equipment parts, shortens the service life of the equipment, and increases equipment maintenance costs. Third, the blade structure design of some slitting modules is unreasonable, which easily leads to problems such as packaging bags sticking together and uneven slitting during the slitting process. This further affects subsequent product sorting and warehousing and transportation links, indirectly reducing the efficiency of the entire production chain. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a sealing device for instant noodle packaging, capable of completing the packaging operation of instant noodles. Furthermore, through improvements to the cutting module, it can complete continuous packaging bag cutting operations, improving the smoothness and continuity of the overall packaging operation, thereby increasing operational efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sealing device for instant noodle packaging, comprising a frame, wherein a heat sealing module, an exhaust module and a cutting module are sequentially arranged on the frame along the material conveying direction, the cutting module comprising a mounting frame, wherein a cutting head and a cutting holder are provided on the mounting frame for cooperation, and a drive shaft is provided in both the cutting head and the cutting holder, wherein a drive source is provided at one end of the two drive shafts and a synchronous gear set is provided at the other end.

[0007] As a further improvement to the above technical solution: The number of the cutter heads is multiple and they are evenly distributed along the circumference of the drive shaft. Each cutter head is equipped with a heating plate on its exterior.

[0008] The number and position of the tool holders correspond to the tool heads.

[0009] The heat sealing module includes a tray with a clearance channel at the center line of the tray, a heating module below the tray, and guide roller assemblies at both ends of the heating module.

[0010] The heating module includes two symmetrically distributed heating blocks, with a material passage gap reserved between the two heating blocks that is coaxially distributed with the clearance channel.

[0011] The exhaust module includes a substrate located above the heat sealing module, an exhaust brush is provided on the lower surface of the substrate, and an adjustment device is provided on one side of the substrate.

[0012] The number of exhaust brushes is multiple, and they are evenly distributed along the length of the substrate.

[0013] The adjustment device includes a positioning frame, in which a vertically installed adjustment screw is provided, and a lifting seat that works in conjunction with the adjustment screw is provided on one side of the base plate.

[0014] The tail end of the slitting module is equipped with a discharge conveyor belt, and a flattening roller is installed above the discharge conveyor belt.

[0015] The beneficial effects of this utility model embodiment are as follows: The sealing equipment for instant noodle packaging includes a frame, on which a heat sealing module, an exhaust module, and a cutting module are sequentially arranged along the material conveying direction.

[0018] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0019] like Figure 1-5 As shown, the sealing equipment for instant noodle packaging in this embodiment includes a frame 1. A heat-sealing module, an exhaust module, and a cutting module are arranged sequentially along the material conveying direction on the frame 1. The cutting module serves as the end-effector of the equipment. The core component is a mounting frame 2, on which are mounted mutually cooperating blades 3 and blade holders 4, both of which have drive shafts 5 passing through them. One end of each drive shaft 5 is connected to a drive source 6 to obtain power, while the other end is synchronized through a synchronous gear set 7 to ensure precise cooperation between the blades 3 and blade holders 4.

[0020] Multiple blades 3 are evenly distributed along the circumference of the drive shaft 5. Each blade 3 is equipped with a heating plate 8 to ensure the sealing effect of the packaging during the cutting process. The number and position of the blade holders 4 correspond to the blades 3, forming a stable cutting pair. In this embodiment, two blades 3 and two blades 4 are used. During operation, the film bag can be cut twice in one rotation of the drive shaft, that is, the front and rear ends of each dough are cut to form a complete packaging bag.

[0021] At the tail of the slitting module, a discharge conveyor belt 19 for conveying finished products is also installed. A flattening roller 20 is set above the discharge conveyor belt 19 to flatten the slitting packaging and flatten the vertically distributed connecting parts at the bottom of the packaging bag after heating, so as to facilitate the boxing operation.

[0022] The heat sealing module is located at the front end of the slitting module and mainly consists of a pallet 9 and a heating module. A clearance channel 10 is provided at the center line of the pallet 9, and the heating module is correspondingly arranged below it. Guide wheel sets 11 are installed at both ends of the heating module to assist in the smooth conveying of materials. The heating module consists of two symmetrically distributed heating blocks 12, with a material passage gap 13 reserved between the two heating blocks 12. This material passage gap 13 is coaxially distributed with the clearance channel 10 on the pallet 9 to ensure that the material can pass smoothly and complete the heat sealing operation.

[0023] The exhaust module is located above the heat sealing module, with the substrate 14 as the mounting carrier. Multiple exhaust brushes 15 are evenly arranged on the lower surface of the substrate 14 to exhaust the air inside the packaging before heat sealing. To adapt to the exhaust requirements of different packaging sizes, an adjustment device is provided on one side of the substrate 14. The front end of the substrate 14 is located behind the heating module to ensure that the exhaust operation is carried out after the bottom of the packaging bag is sealed.

[0024] The adjustment device includes a positioning frame 16, inside which an adjustment screw 17 is vertically mounted. A lifting seat 18, adapted to the adjustment screw 17, is provided on the corresponding side of the base plate 14. The lifting seat 18 has guide rods located on both sides of the adjustment screw 17. Rotating the adjustment screw 17 drives the base plate 14 to rise and fall, thereby adjusting the contact height between the exhaust brush 15 and the material.
