Description

Technical Field

[0001] This utility model relates to the field of sandwich seaweed production and preparation technology, and in particular to an automatic sandwich seaweed sandwich device. Background Technology

[0002] Stuffed seaweed typically consists of two sheets of seaweed and a filling in the middle. The filling usually uses a multi-layered dry material composite, such as crushed peanuts, sesame seeds, and seasoning powder. By combining different particle sizes, the filling density is improved, and the layers of texture are enhanced.

[0003] Currently, most manufacturers still rely on manual spreading of fillings for making seaweed sandwiches. This method is not only labor-intensive and inefficient, but also prone to uneven distribution of the fillings due to inconsistent worker techniques, affecting product quality consistency.

[0004] To address this issue, Chinese invention patent CN109588652B proposes an automatic seaweed filling device. This device uses a hydraulic cylinder to drive clamping blocks to compress and fix the seaweed, while simultaneously employing an automatic extrusion device to fill the filling, thus reducing manual intervention and improving production efficiency. However, in this technical solution, because the seaweed sheets are clamped vertically, the filling material naturally sinks under gravity, resulting in a thicker accumulation of filling material near the bottom and a relatively sparse accumulation at the top, ultimately affecting the product's texture and uniformity.

[0031] The specific technical solutions of this utility model are further described below to enable those skilled in the art to further understand this utility model, without constituting a limitation on its rights.

[0032] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0033] [Example 1] Please refer to Figure 1-6An automatic filling device for sandwich seaweed includes a frame and a conveyor belt horizontally mounted on the frame. The frame consists of two vertically arranged rectangular metal plates, with multiple reinforcing rods (not shown) welded horizontally between the two rectangular metal plates. Each metal plate has two support legs welded to its bottom. A material spreading mechanism and a pressing mechanism are sequentially arranged on the frame along the conveyor belt's transport direction. The conveyor belt is mainly used to transport the lower layer of seaweed sheets and the seaweed to be pressed. The material spreading mechanism is used to evenly spread the filling material on the upper surface of the lower layer of seaweed sheets. The pressing mechanism is used to press the lower layer of seaweed sheets with the filling material onto the upper layer of seaweed sheets, which are then covered with the filling material, to ensure compaction and tightness for subsequent oven baking.

[0034] The material feeding mechanism includes a support frame fixedly installed on the top of the machine frame, a hopper frame fixedly installed on the top of the support frame, a sandwich hopper installed on the top of the hopper frame, and a weight sensor installed between the sandwich hopper and the hopper frame. The weight sensor is used to monitor the weight of the sandwich material inside the sandwich hopper.

[0035] A discharge valve is installed at the bottom outlet of the sandwich hopper. A distribution roller connected to a power source is rotatably mounted on the support frame at the bottom of the discharge valve. Multiple distribution grooves are evenly opened inward along the circumference of the roller surface. A brush roller is arranged parallel to the support frame downstream of the distribution roller. The rotation direction of the brush roller is opposite to that of the distribution roller, and the bristles of the brush roller are in contact with the bottom of the distribution groove. The distance between the bristles of the brush roller and the conveyor belt is less than 3mm. When in use, the discharge valve is opened, and the sandwich material falls into the distribution groove of the distribution roller and is driven by the bristles of the brush roller to be evenly spread on the upper surface of the lower seaweed sheet.

[0036] The pressing mechanism includes a vertical plate fixedly mounted on the top of the frame, with a pressure roller rotatably mounted on the plate and connected to a power source. Below the pressure roller and inside the conveyor belt, a horizontal bracket is movably mounted, with multiple idler rollers arranged side-by-side along the conveyor belt's transport direction on the bracket. A lifting mechanism inside the conveyor belt drives the bracket to move vertically up and down. In use, workers place the upper layer of seaweed sheets on top of the lower layer of seaweed sheets, forming the seaweed to be pressed. The lifting mechanism raises the bracket, lifting the conveyor belt and the seaweed to be pressed together until they contact the pressure roller, thus compacting and pressing the seaweed. Throughout the process, the idler rollers effectively reduce friction between the conveyor belt and the bracket, making the equipment operate more stably.

[0037] Furthermore, to prevent the filling material from becoming too thick, the material spreading mechanism also includes a vertically arranged positioning plate and a scraper plate. The positioning plate is fixedly welded to the support frame downstream of the brush roller. The positioning plate has at least two symmetrical positioning holes, each with a positioning bolt inserted into it. The scraper plate is arranged parallel to one side of the positioning plate, and has vertically arranged adjustment grooves corresponding to the positioning bolts. The positioning plate and the scraper plate are secured together by a clamping nut fitted onto the positioning bolt. The lower end of the scraper plate, facing the brush roller, has a guide slope facing the conveyor belt's conveying direction. The distance between the lower end of the scraper plate and the conveyor belt is the scraping gap. When the lower layer of seaweed sheet passes the scraper plate, if the thickness of the lower layer of seaweed sheet plus the filling material exceeds the scraping gap, the excessive filling material is scraped off via the guide slope. By loosening / tightening the clamping nut, the height of the scraper plate can be adjusted, thereby changing the size of the scraping gap to adapt to different process requirements.

[0038] Preferably, the inclination angle of the guide slope is 50-70°.

[0039] A base plate is fixedly installed under the frame. The four corners of the base plate are fixedly welded to the support legs of the frame. A geared motor for driving the conveyor belt is installed on the base plate. A drive pulley is fixedly installed on the power output end of the geared motor. A driven pulley is fixedly installed on the roller shaft of the brush roller. The drive pulley and the driven pulley are connected by a belt for transmission.

[0040] In the above structure, a drive gear is coaxially fixedly installed on the roller shaft of the distributing roller, and a driven gear that meshes with the drive gear is coaxially fixedly installed on the roller shaft of the brush roller.

[0041] Specifically, the lifting mechanism includes a support plate fixedly installed on the inner frame of the conveyor belt. Multiple linkage-controlled lifting cylinders are fixedly installed on the upper surface of the support plate, and the power output end of the lifting cylinders is fixedly connected to the lower surface of the bracket.

[0042] A funnel-shaped feeder with an open top is fixedly welded to the bottom of the frame. The two opposite sides of the feeder are welded and fixed to the frame. The bottom of the feeder narrows towards the center to form an outlet. A recycling box for recycling sandwich materials is fixedly installed on the bottom plate below the outlet.

[0043] The aforementioned recycling bin has a downward-facing receiving trough at the top, and a recycling port leading to the receiving trough is located on one side of the bin. A hinged, closable door is installed at the outer edge of the recycling port, and an arc-shaped guide plate facing the recycling port is installed between the lower edge of the recycling port and the wall of the receiving trough. When the material in the receiving trough accumulates to a set height, the operator can open the door for centralized recycling. The recycled material, after screening, can be reused in the sandwich hopper, reducing raw material waste.

[0044] Working Principle: In use, the lower layer of seaweed sheets is first laid on a conveyor belt, which is then driven forward at a uniform speed by a geared motor. The mixed material in the sandwich hopper flows through a discharge valve into the rotating distribution roller's distribution trough. The distribution roller engages with a counter-rotating brush roller, which uses bristles to evenly sweep the material from the distribution trough onto the surface of the lower layer of seaweed sheets. An adjustable scraper precisely controls the thickness of the layer; excessively thick sandwich material is guided to a feeder for recycling via a guide slope. Subsequently, a manual or robotic arm places the upper layer of seaweed sheets over the laid-out lower layer. When the composite seaweed enters the pressing station, a lifting cylinder pushes the support frame upwards, causing the support roller to press against the conveyor belt. This, in conjunction with the rotating pressure roller, creates uniform linear pressure, ensuring consistent sandwich layer thickness. The recycling bin uses an arc-shaped guide plate to centrally collect scattered materials. The entire device completes the processes of spreading, leveling, covering, and pressing during horizontal conveying, effectively avoiding the material accumulation problem caused by traditional vertical operations.

[0045]

Example 2

[0046] A seaweed limiting plate is vertically installed on the side of the frame away from the seaweed placement box. The seaweed limiting plate is positioned directly opposite the seaweed outlet. A limiting cylinder perpendicular to the conveyor belt conveying direction is fixedly installed on the frame adjacent to the seaweed limiting plate. The power output end of the limiting cylinder is fixedly connected to the seaweed limiting plate.

[0047] By setting up the above structure, the upper layer of seaweed sheets are placed into the seaweed placement box from top to bottom. When the lower layer of seaweed sheets with the filling material is conveyed to the side push station (located downstream of the material spreading mechanism and upstream of the pressing mechanism) by the conveyor belt, the side push cylinder is activated. Its power output end pushes the push plate, which moves perpendicular to the conveyor belt conveying direction, and smoothly pushes the bottom layer of upper seaweed sheets out from the seaweed outlet, allowing them to slide above the conveyor belt and cover the lower layer of seaweed sheets with the filling material.

[0048] Meanwhile, to precisely control the covering position of the upper seaweed sheet and prevent deviation, a seaweed limiting plate located on the other side of the conveyor belt can be adjusted perpendicular to the conveying direction under the action of a limiting cylinder. By controlling the stroke of the limiting cylinder, the seaweed limiting plate can move to a predetermined position, precisely blocking and positioning the outer edge of the upper seaweed sheet that is pushed out to the side. In this way, during the sliding process, the outer edge of the upper seaweed sheet is blocked and positioned by the seaweed limiting plate, while the inner edge naturally falls on the target coverage area of ​​the lower seaweed sheet, ensuring alignment of the upper and lower seaweed sheets.

[0049] 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 embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
