Description

Technical Field

[0001] The invention relates to the technical field of umbrella processing, in particular to a process for molding plastic umbrella surfaces. Background Art

[0002] In the prior art, the production of plastic umbrellas usually adopts the traditional manual or semi-automatic method, which requires 8 triangular umbrella cloths to be manually sewn or welded together to form a complete umbrella. This method is not only inefficient, but also difficult to ensure product quality, and is prone to problems such as uneven sewing and loose welding. Summary of the invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a plastic umbrella fabric forming process, which combines the traditional 8-piece triangle forming into 2-piece forming, realizes the integration of umbrella cloth welding and cutting processes, and greatly improves production efficiency and product stability.

[0004] The technical solution of the present invention is as follows:

[0005] A process for forming a plastic umbrella surface comprises the following steps:

[0006] S1. Preliminary cutting: The plastic umbrella cloth roll is used as the raw material, and the plastic umbrella cloth is cut into flat half pieces using cutting equipment.

[0007] S2, automatic welding: the flat half sheet is cut into 4 triangular umbrella cloths for three times, and then the triangular umbrella cloths are welded in sequence into a semi-finished product; in the semi-finished product, there is a raised strip at the welding position between two adjacent triangular umbrella cloths;

[0008] S3. Final welding: Use a welding fixture to firmly connect the parts of the two semi-finished products together, and weld the inner edges of the two semi-finished products to form a finished product.

[0009] The flat half piece consists of a periphery and a connecting edge, three square notches are evenly distributed on the periphery, and a semicircular notch is opened in the middle of the connecting edge.

[0010] There are also raised strips at the inner edge welding points of the two semi-finished products in the finished product.

[0011] Technical effects and advantages of the present invention:

[0012] Using fully automated welding equipment, 8 pieces of triangular umbrella cloth are combined into 2 large umbrella cloths through high-temperature welding technology, which are automatically welded and cut to form the umbrella surface. This greatly improves production efficiency and ensures the uniformity and stability of welding quality.

[0013] After welding is completed, automatic cutting is performed immediately to ensure the accuracy and consistency of cutting, reducing the errors caused by multiple transfers and positioning in traditional processes.

[0014] The entire process is precisely controlled by the PLC control system to achieve fully automated production, greatly reducing labor costs and improving product quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1

[0020] A process for forming a plastic umbrella surface comprises the following steps:

[0021] S1. Preliminary cutting: The plastic umbrella cloth roll is used as the raw material, and the plastic umbrella cloth is cut into two flat half sheets 1 using a cutting device, namely Figure 1 Shape shown.

[0022] S2, automatic welding: each flat half sheet is cut into 4 triangular umbrella cloths 11 after three times, and 2 sheets have 8 triangular umbrella cloths, and then each 4 triangular umbrella cloths are welded into a semi-finished product form 2 in sequence; the welding part between two adjacent triangular umbrella cloths in the semi-finished product form has a raised strip 21; that is, the plastic umbrella cloth will undergo three fully automatic welding and cutting processes, and the plastic umbrella cloth will be processed into Figure 2 The semi-finished product form is shown.

[0023] S3, final welding: Use a welding fixture to firmly connect the parts of the two semi-finished products together, and weld the inner edges 3 of the two semi-finished products to form Figure 3 , the finished product shown.

[0024] like Figure 1 As shown, the flat half sheet is composed of a periphery 12 and a connecting edge 13 , the periphery 12 is evenly distributed with three square notches 14 , and the connecting edge 13 is provided with a semicircular notch 15 in the middle.

[0025] like Figure 3 As shown, there are also raised strips 31 at the inner edge welding points of the two semi-finished products.

[0026] The raised strips not only facilitate welding, but also serve as reinforcement ribs.

[0027] Embodiment 2

[0028] 1. The three-step molding process of the plastic umbrella cloth uses a fully automated design to achieve the integration of umbrella cloth welding and cutting processes.

[0029] 2. The advanced cutting equipment can cut the plastic umbrella cloth rolls efficiently and accurately.

[0030] 3. By introducing three fully automatic welding and cutting processes, we have achieved a high degree of automation in the processing of plastic umbrella cloth.

[0031] 4. Innovative merging welding technology, we merge 8 pieces of umbrella cloth into 2 pieces, and then perform the final firm welding.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
