Abstract

The utility model discloses a hot melt adhesive coating head, comprising a scraper holder, a scraper plate and baffle plates; the baffle plates are arranged at both sides of the scrapper holder; the scraper holder is a tubular structure with both ends closed; one end of the scraper holder is provided with an oil inlet tube and an oil outlet tube; the scraper plate is arranged at the lower end of the scraper holder, forming a negative angle with the horizontal plane. The hot melt adhesive coating head of the utility model is applicable to liquid adhesive as well as hot-melt adhesive.

Description

PUR is coated with head

Technical field

The utility model relates to a kind of PUR that utilizes as coating material, and base materials such as woven, nonwoven are carried out compound compounding machine, and the PUR that particularly relates to this machine is coated with head.

Background technology

Existing compounding machine, be a kind of liquid glue that utilizes as coating material, base materials such as woven, nonwoven, waterproof humidity-permeant film are carried out compound equipment.This machine mainly by the feeding unit of coating material, be coated with head and wrap-up constitutes.The main effect that is coated with head is liquid glue to be applied on the engraved roll, and this glue to be transferred to the surface of base material by engraved roll.The existing head that is coated with mainly comprises and scrapes tool rest, scrapes knife plate and baffle plate.Scrape knife plate and become positive angle to be arranged on level to scrape on the tool rest, baffle plate is arranged on the both sides of scraping tool rest, and the edge of a knife of scraping knife plate is close on the surface of compounding machine engraved roll.During work, liquid glue is fed in the space of scraping between tool rest and the engraved roll, and the engraved roll of rotation makes and is coated with head this glue is applied on the engraved roll, and is transferred to the surface of base material by engraved roll.The existing PUR of head to need using under molten state that be coated with obviously can't be suitable for.Simultaneously, so often scrape very untotally to the lip-deep liquid glue of engraved roll because the existing knife plate of scraping becomes positive angle to be arranged on level to scrape on the tool rest.

The utility model content

The technical problems to be solved in the utility model provides a kind of PUR and is coated with head, and it not only adapts to the use of PUR, and can make and be coated with head with this and scrape the engraved roll surface that the knife plate edge of a knife is close to and scrape totally.

For solving the problems of the technologies described above, a kind of PUR of the utility model is coated with head, it contains scrapes tool rest, scrapes knife plate and baffle plate, baffle plate is arranged on the both sides of scraping tool rest, described to scrape tool rest be tubular-shaped structures, its closed at both ends and at one end be provided with oil inlet pipe and flowline, describedly scrapes the lower end that knife plate becomes negative angle to be arranged on level to scrape tool rest.

Described flowline is longer than oil inlet pipe in tubular length of scraping tool rest inside and is scraped the length of tool rest inside at this.

Since scrape tool rest be tubular-shaped structures, its closed at both ends and at one end on be provided with oil inlet pipe and flowline, high temperature oil enters the tubular of sealing from oil inlet pipe and scrapes in the tool rest, flow out from flowline again, high temperature oil makes the body of scraping tool rest be elevated to certain temperature during this period, make the state that is fed into the PUR maintenance fusing of scraping between tool rest and the engraved roll like this, thereby make to be coated with head this glue is applied on the engraved roll, and be transferred to the surface of base material by engraved roll.Become negative angle owing to be arranged on the knife plate of scraping of scraping the tool rest lower end with level simultaneously, be close to the lip-deep knife plate edge of a knife of scraping of engraved roll, not only the lip-deep PUR of engraved roll is scraped, and shovel, therefore the lip-deep PUR of engraved roll can be scraped totally by shovel, and wire drawing (leaving loose ends) phenomenon can not take place.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is that the A that scrapes tool rest in the utility model shown in Figure 1 is to view.

Fig. 3 is the left view of Fig. 2.

1. scrape tool rest among the figure, 2. scrape knife plate, 3. flowline, 4. oil inlet pipe, 5. baffle plate, 6. engraved roll.

The specific embodiment

Among Fig. 1, PUR is coated with head and contains and scrape tool rest 1, scrape knife plate 2 and baffle plate 5.Baffle plate 5 is arranged on the both sides of scraping tool rest 1, scrapes tool rest 1 for tubular-shaped structures, its closed at both ends and at one end be provided with oil inlet pipe 4 and flowline 3, scrapes the lower end that knife plate 2 becomes negative angle to be arranged on level to scrape tool rest 1.For improving the heat exchanger effectiveness of high temperature oil in scraping tool rest 1, flowline 3 is longer than oil inlet pipe 4 in tubular length of scraping tool rest 1 inside and is scraped the length of tool rest 1 inside at this, as shown in Figures 2 and 3.The edge of a knife of scraping knife plate 2 is close on the engraved roll 6 of compounding machine, as shown in Figure 1.During work, the PUR that in the melten gel jar, melts, fed in the space of scraping between tool rest 1 and the engraved roll 6, high temperature oil is tubularly scraped in the tool rest 1, is flowed out from flowline 3, makes and scrape tool rest 1 and keep certain temperature from what oil inlet pipe 4 entered sealing, can make PUR be in molten state all the time like this, thereby make to be coated with head this glue is applied on the engraved roll 6, and be transferred to the surface of base material.Because being arranged on the knife plate 2 of scraping of scraping tool rest 1 lower end becomes negative angle with level, be close to the engraved roll 6 lip-deep edges of a knife of scraping knife plate 2, not only engraved roll 6 lip-deep PURs are scraped, and shovel, therefore engraved roll 6 lip-deep PURs can be scraped totally by shovel, and wire drawing (leaving loose ends) phenomenon can not take place.When high temperature oil is not advanced in the inside of scraping tool rest 1, be coated with head and go for liquid glue, so this is coated with head and both had been applicable to liquid glue, also has been applicable to the use of PUR.

Claims

1. a PUR is coated with head, it contains scrapes tool rest, scrapes knife plate and baffle plate, baffle plate is arranged on the both sides of scraping tool rest, it is characterized in that: described to scrape tool rest be tubular-shaped structures, its closed at both ends and at one end be provided with oil inlet pipe and flowline, describedly scrapes the lower end that knife plate becomes negative angle to be arranged on level to scrape tool rest.

2. PUR according to claim 1 is coated with head, it is characterized in that: described flowline is longer than oil inlet pipe in tubular length of scraping tool rest inside and is scraped the length of tool rest inside at this.
