Abstract
Description
Technical fields:
[0002] This utility model relates to the field of experimental auxiliary equipment technology, specifically a bag-supporting device for tobacco boxes. Background technology:
[0004] In tobacco processing, to prevent problems such as squeezing, breakage, moisture, or insect damage during subsequent transportation and storage, semi-finished products such as tobacco shreds produced in the initial or finishing stages are usually protectively packaged. For products with higher protection requirements, cardboard boxes and inner bags are generally used for packaging. During the packaging process, because the inner bags nested inside medium to large cardboard boxes are large or their openings are not easy to keep upright, workers need to manually locate the bag openings and lay the inner bags flat inside the packaging box. Due to the large volume of the inner bags, manual laying is time-consuming and reduces work efficiency.
[0005] In existing technology, the bag opening is manually located and the inner bag is laid flat and attached inside the tobacco box. This manual laying of the inner bag is time-consuming and affects the efficiency of subsequent operations. Utility model content:
[0007] The purpose of this invention is to provide a bag support device for tobacco boxes to solve the problems mentioned in the background art.
[0008] This utility model is implemented by the following technical solution:
[0009] A tobacco box inner bag support device includes a sliding ruler, two support plates, two handles, two limiting plates, and two compression springs. The sliding ruler has support plates and handles symmetrically arranged on both sides from the center. One end of each handle is fixed to the top of one side of a support plate. A rectangular groove is formed on both the support plates and the handles. A square groove is formed on each handle. The rectangular and square grooves are connected. The sliding ruler slides through the rectangular groove. Limiting plates are fixed to the lower surfaces of both ends of the sliding ruler. The limiting plates slide within the square grooves. Compression springs are located within the square grooves, between the support plates and the limiting plates. One end of each compression spring abuts against the surface of a support plate, and the other end abuts against the surface of a limiting plate.
[0010] Preferably, the surface of the slide ruler has scale values.
[0011] Preferably, the edge of the support plate near the handle has rounded corners.
[0012] Preferably, the thickness of the support plate is - millimeters.
[0013] Preferably, the support plate and handle are made of plastic.
[0014] The advantages of this utility model are: simple operation and high efficiency. Simply put the inner bag into the tobacco box, and then pull the handles to both sides to open the two support plates, which can quickly flatten the inner bag. Attached image description:

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-7 This utility model provides a technical solution for a bag support device for the inner bag of a tobacco box:
[0027] A tobacco box inner bag support device includes a sliding ruler 1, two support plates 2, two handles 3, two limiting plates 4, and two compression springs 5. The sliding ruler 1 has scale values on its surface for easy measurement of the width of the inner side of the box. The support plates 2 and handles 3 are symmetrically slidable on the sliding ruler 1 from the center to both sides. One end of the handle 3 is fixed to the top of one side of the support plate 2. The support plates 2 and handles 3 are made of plastic. The thickness of the support plates 2 is 2-3 mm. The edge of the support plate 2 near the handle 3 has a rounded corner 2.1 to prevent damage to the nested inner bag during use. A rectangular groove 23 is provided on the handle 3, and a square groove 3.1 is provided on the handle 3. The rectangular groove 23 and the square groove 3.1 are connected. The sliding ruler 1 slides through the rectangular groove 23. Limiting plates 4 are fixed on the lower surfaces of both ends of the sliding ruler 1. The limiting plates 4 slide in the square groove 3.1. A compression spring 5 is provided in the square groove 3.1. The compression spring 5 is located between the support plate 2 and the limiting plate 4. One end of the compression spring 5 abuts against the surface of the support plate 2 and the other end abuts against the surface of the limiting plate 4. When the bag is not supported, the two support plates 2 can quickly fit together under the action of the compression spring 5.
[0028] The working principle is as follows: Place the tobacco box on the ground, measure the box body using the sliding ruler 1 to quickly select a suitable inner bag, put the inner bag into the box, open the bag opening, and insert the two support plates 2 into the bag opening. Then, hold the handles 3 on both sides with both hands and pull them to the sides. While pulling, the distance between the two support plates 2 gradually increases, using the two support plates 2 to quickly open the inner bag until the surfaces of the two support plates 2 contact the inner surface of the box body. Finally, the entire inner bag is laid flat inside the box body. Then, slide the handles 3 on both sides towards the middle to quickly remove the device from the inner bag. Repeat the action to lay the inner bag of the next tobacco box.
[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
