Description

Technical Field

[0001] The utility model relates to the field of resin product processing equipment, in particular to a resin centralized feeding system. Background Art

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the embodiments and drawings.

[0021] In the first embodiment, Figure 1As shown, a centralized resin feeding system comprises: a batching reaction tank 1, which is arranged in a synthesis workshop and used for preparing liquid resin; an intermediate tank 2, which is arranged in a coating workshop and used for temporarily storing liquid resin; a coating device 3a or 3b, which is arranged in the coating workshop and used for pre-coating liquid resin to a fiber-based cloth; a first feeding pipeline 4, which is used for connecting the batching reaction tank 1 and the intermediate tank 2; a second feeding pipeline 5, which is used for connecting the intermediate tank 2 and the coating device 3a or 3b; and a material pump 6 is provided on both the first feeding pipeline 4 and the second feeding pipeline 5. This resin feeding method makes full use of the advantage that the coating workshop is adjacent to the synthesis workshop, and sets the intermediate tank 2 to temporarily store liquid resin, and then uses a pipeline to transport it to the coating device 3a or 3b such as a roller coater and a clamping machine, so as to directly carry out pre-coating production; it can not only save the weekly cleaning of the batching reaction tank 1, but also avoid the waste of a large number of wall-mounted residual resins in the resin barrels and the hazardous waste generated during cleaning, which can reduce 90% of the hazardous waste treatment costs, reduce the labor intensity of the operating staff, and improve the cleanliness of the production workshop.

[0022] In the first embodiment, Figure 1 As shown, the intermediate tank 2 is equipped with a stirring device 201 and an insulating jacket 202, and the insulating jacket 202 uses electric heating or circulating hot water. Stirring can ensure the uniform dispersion of the various components of the resin, avoid uneven spots, and thus improve the quality of the final product. Heating can reduce the viscosity of the resin, making it easier to stir and handle, which is very important for subsequent coating operations, can improve production efficiency and ensure product consistency and quality. Since the heat requirement of the insulating jacket 202 is not high, electric heating is usually used to reduce the external circulating water pipeline, make the equipment more compact as a whole, and also facilitate reliable temperature control.

[0023] In the first embodiment, Figure 1 As shown, the second feeding pipeline 5 is provided with an insulation sleeve 501. The insulation sleeve 501 is made of insulation materials such as glass fiber, rock wool, polyurethane foam, etc., which is wrapped around the outside of the second feeding pipeline 5 to form an insulation layer, which is used to reduce the temperature fluctuation of the resin during the transportation process, which is beneficial to the subsequent coating operation.

[0024] In the first embodiment, Figure 1 As shown, the batching reaction tank 1, the intermediate tank 2 and the coating equipment 3a or 3b are arranged one by one, and together with the first feeding pipeline 4 and the second feeding pipeline 5 form an independent feeding line. Figure 1 There are two independent feeding lines in this form. In this form, the two feeding lines can supply coating equipment 3a (such as medical bandage coating machine) and coating equipment 3b (such as industrial bandage coating machine) respectively, that is, they can operate independently according to the order situation to produce different products, and at the same time, they can prevent mutual contamination between the feeding lines.

[0025] In the second embodiment, Figure 2As shown, there are at least two feed lines, each of which is provided with a first bypass line 7 between its respective first feed lines 4, and a second bypass line 8 between its respective second feed lines 5. In this embodiment, the two feed lines are connected by the first bypass line 7 and the second bypass line 8 before and after the intermediate tank 2, respectively, and the reaction tank 1, the intermediate tank 2 and the coating equipment 3a can be used in one and standby in the other, which enhances the flexibility of the feed system and can still ensure orderly and reliable operation of production in the case of partial equipment maintenance or failure.

[0026] In the third embodiment, Figure 3 As shown, two batching reaction tanks 1 and two coating devices 3a share one intermediate tank 2; Example 4, as shown Figure 4 As shown, two batching reaction tanks 1 and one coating device 3a share one intermediate tank 2; Example 5, as shown Figure 5 As shown, one batching reaction tank 1 and two coating devices 3a share one intermediate tank 2. In the above embodiments, according to product characteristics and production scale, the intermediate tank 2 is set in the resin centralized feeding system in different ways to meet different production requirements. In this form, all coating devices 3a are required to be of the same type to avoid contamination of materials between each other.

[0027] Obviously, the above embodiments of the present invention are only examples for explaining the present invention, and are not intended to limit the implementation methods of the present invention. Other obvious changes or modifications derived from the essence of the present invention still fall within the protection scope of the present invention.
