[0002] Wrapping paper rolls are a general term for a type of paper used for packaging purposes, which can be divided into ordinary wrapping paper, special wrapping paper, trademark paper, oil-proof wrapping paper, moisture-proof wrapping paper, etc. They usually have high strength and toughness. Various types of wrapping paper have different properties and uses. In the production process, locking mechanisms are often required. However, traditional mechanisms generally use threaded locking, which takes a long time for operators to change products, increases labor intensity, and has poor adaptability to installation.

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, an elastic locking mechanism for packaging paper rolls is proposed. The product can be quickly installed, replaced and locked by rotating a locking card, which makes the operation of the device simple, greatly shortens the time for replacing products, reduces labor intensity, and improves productivity. The product can be used to achieve adaptive and stable locking operations, making the device highly adaptable to installation. Summary of the invention

[0004] The object of the present invention is to provide an elastic locking mechanism for a packaging paper roll to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A packaging paper roll elastic locking mechanism comprises a vertically arranged limit mounting plate, a guide mounting cylinder is horizontally extended to the left at the middle position of the limit mounting plate, a locking shaft is horizontally penetrated through the middle position of the guide mounting cylinder, a locking card is vertically penetrated through the right end of the locking shaft, a rotating column is longitudinally penetrated through the middle position of the right end of the locking shaft, and a rotating groove is provided at the right end of the locking shaft to cooperate with the locking card, a rotating cylinder is coaxially and horizontally arranged at the left end of the guide mounting cylinder, a locking spring is provided on the outside of the elastic locking force adjusting screw to cooperate with the rotating cylinder and the guide mounting cylinder, and a product locking plate is vertically arranged on the locking shaft on the left side of the locking card.

[0007] As a further solution of the present invention: a product is fixed on the locking column between the product locking plate and the limiting mounting plate.

[0008] As a further solution of the present invention: an elastic locking force adjusting screw extending out of the guide mounting cylinder and the rotating cylinder is arranged on the left end of the locking shaft.

[0009] Compared with the prior art, the beneficial effects of the present invention are: the product can be quickly installed, replaced and locked by rotating the locking card, which makes the operation of the device simple, greatly shortens the time for replacing products, reduces labor intensity, and improves productivity. The product can achieve adaptive and stable locking operations, making the device highly adaptable to installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0014] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0015] Embodiment 1

[0016] See also Figures 1-2The locking plate 6 of the embodiment of the present invention is a kind of product locking mechanism.

[0017] By rotating the locking card 4 to make it parallel to the locking shaft 5, remove the product locking plate 6, install or replace the product in conjunction with the locking shaft 5, and then install the product locking plate 6. At the same time, rotate the locking card 4 vertically to limit the product from sliding to the right. The limit mounting plate 7 on the left side of the product is clamped and fixed under the action of the locking spring 2. By rotating the locking card 4, the product can be quickly installed, replaced and locked, which makes the operation of the device simple, greatly shortens the time for changing products, reduces labor intensity, and improves productivity.
