Description

Technical Field

[0001] The utility model belongs to the technical field of fresh-keeping bag storage, and particularly relates to a fresh-keeping bag folding device. Background Art

[0002] Fresh-keeping bags mainly refer to bags made of food preservative film, which are mainly used for storing vegetables, fruits, grains, cooked foods and other foods, and are widely used in daily life.

[0003] Fresh-keeping bags are divided into two storage methods: rolled storage and flat storage. When taking out a single fresh-keeping bag from the stacked ones, it is usually taken from the upper side. When pulling it out, it is easy to collapse and needs to be manually sorted and reset, resulting in the problem that it is relatively troublesome to take out the stacked conventional fresh-keeping bags.

[0004] Therefore, we propose a fresh-keeping bag folding device to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem that it is relatively troublesome to take out the stacked conventional fresh-keeping bags, and a fresh-keeping bag folding device is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] The fresh-keeping bag folding device includes a support frame. The upper end of the support frame is fixedly connected with a folding box. The front end of the folding box is fixedly connected with a threaded frame. A lifting plate is slidably installed on the inner wall of the front part of the folding box. A bolt is threadedly installed inside the threaded frame. The lower part of the bolt is threadedly connected with the lifting plate. A weight is movably installed inside the folding box. Place the fresh-keeping bag in the folding box, then turn the bolt to drive the lifting plate to rise, so that a gap is generated between the lower part of the lifting plate and the folding box. Rub out the fresh-keeping bag from the bottom of the folding box with fingers. When too much fresh-keeping bag is pulled out, turn the bolt in the reverse direction to reduce the gap between the lifting plate and the folding box, which is convenient for adjusting and matching the thickness of a single fresh-keeping bag and convenient for folding and taking out the fresh-keeping bag.

[0008] Preferably, a resistance block is fixedly connected to the lower part of the lifting plate. The resistance block is used to provide friction for the extra pulled-out fresh-keeping bag and reduce the possibility of pulling out too much fresh-keeping bag.

[0009] Preferably, the folding box includes a box body and an inclined plate. Finger grooves are formed in the front parts of the box body and the inclined plate. After stacking the fresh-keeping bags on the inclined plate, insert the fingers into the finger grooves and then rub out the fresh-keeping bag, which is convenient for taking out the fresh-keeping bag with fingers.

[0010] Preferably, the threaded frame includes a connecting rod and a bearing. The bearing is fixedly connected to the middle of the connecting rod. The bearing is convenient for guiding the spiral movement of the bolt.

[0011] Preferably, the bolt includes a knob, a swivel ring and a threaded bolt body. The knob is fixedly connected to the upper end of the threaded bolt body, and the swivel ring is fixedly connected to the upper part of the threaded bolt body. Turning the knob drives the swivel ring and the threaded bolt body to rotate.

[0012] Preferably, the lifting plate includes a plate body, slide bars and nuts. The slide bars are symmetrically and fixedly connected to the sides of the plate body, and the rear end of the nut is fixedly connected to the plate body. Turning the knob drives the threaded bolt body to rotate, drives the nut to rise or fall through the threaded bolt body, and acts on the plate body through the nut, facilitating the adjustment of the gap on the lower side of the plate body.

[0013] Preferably, the resistance block includes a connecting plate and a stepped plate. The rear end of the stepped plate is fixedly connected to the lower part of the connecting plate. When rubbing the fresh-keeping bag outwards, the stepped plate provides a backward force for the extra fresh-keeping bag on the upper side, further reducing the possibility of taking out multiple fresh-keeping bags.

[0014] In summary, the technical effects and advantages of the present utility model are as follows:

[0015] 1. Place the fresh-keeping bag in the folding box, then turn the bolt to drive the lifting plate to rise, so that there is a gap between the lower part of the lifting plate and the folding box. Rub out the fresh-keeping bag with fingers from the bottom of the folding box. When too much fresh-keeping bag is pulled out, turn the bolt in the reverse direction to reduce the gap between the lifting plate and the folding box, facilitating the adjustment of the thickness of a single fresh-keeping bag and making it convenient to fold and take the fresh-keeping bag.

[0016] 2. Turning the knob drives the threaded bolt body to rotate, drives the nut to rise or fall through the threaded bolt body, and acts on the plate body through the nut, facilitating the adjustment of the gap on the lower side of the plate body. BRIEF DESCRIPTION OF THE DRAWINGS
