Description

Technical Field

[0001] The utility model belongs to the technical field of large-scale casting machine equipment, and in particular relates to a casting box with uniform casting thickness. Background Art

[0002] The casting machine is the main equipment for producing cast film. Its main production process is: the slurry is drawn out from the casting barrel through the pipeline by air pressure, and spread on the conveyor line through the casting box to form a slurry with a certain width and thickness, and then the casting film is formed by heating and hot air baking in the casting box. In the casting machine, the casting box is an important connecting device between the casting slurry and the casting equipment. The commonly used casting box is usually composed of a long baffle plate, two sponge pads and a casting scraper. The long baffle plate and the bottom of the sponge pad are close to the conveyor line, and the end faces of the casting scraper are respectively close to the two sponge pads to prevent leakage. The scraper can adjust the thickness up and down. When the casting machine is running, the conveyor line drives forward and brings the casting slurry out from the bottom of the scraper. When the casting scraper is close to the sponge pads on both sides, because the sponge pads have a certain memory and are irreversible, the height of the left and right sponge pads is different, resulting in different casting thicknesses, which affects the normal operation of the casting production. Utility Model Content

[0003] The utility model proposes a casting box with uniform casting thickness, which can effectively solve the problem that the left and right heights of the casting scraper are inconsistent due to the different heights caused by the deformation of the sponge pad, thereby ensuring the uniform casting thickness.

DETAILED DESCRIPTION

[0022] The present invention will be further described below by way of embodiments and in conjunction with the accompanying drawings:

[0023] like Figure 1-6 As shown, a casting box with uniform casting thickness is mainly composed of a casting scraper 1, a long baffle plate 4, two sponge pads 3 and two correction baffles 2. Among them, the casting scraper 1 and the long baffle plate 4 are arranged at intervals in front and back, and the casting scraper 1 is arranged above the rear end of the conveyor line 6 extending forward and backward, and the long baffle plate 4 is located at the rear side of the rear end of the conveyor line 6. The casting scraper 1 includes a scraper handle 1-2 and a cylindrical scraper surface 1-1 sleeved on the scraper handle 1-2. The casting scraper can move up and down relative to the conveyor line 6. The installation structure of the casting scraper and the long baffle plate is a prior art and will not be repeated here.

[0024] In order to prevent the sponge pad from deformation and to correct the sponge pad, a correcting baffle 2 is correspondingly arranged on the left and right outer sides of the two sponge pads 3, and each correcting baffle 2 is arranged on the long baffle rear plate 4 through a corresponding mounting structure. In order to prevent the leakage of the casting slurry, the inner side surface of each sponge pad is always in close contact with the end surface of the scraper surface, and the lower end of the long baffle rear plate 4 and the lower end of each sponge pad 3 are in close contact with the conveyor line 6. Since each correcting baffle does not contact the conveyor line and the casting scraper, that is, the correcting baffle is only used to correct the sponge pad and prevent the sponge pad from deformation, it does not affect the height of the casting scraper.

[0025] The mounting structure includes a mounting bolt 5. A mounting groove 2-1 is provided on the correction baffle 2, which is open downward and is used to insert the correction baffle 2 into the long baffle rear plate 4. The mounting bolt 5 passes through the rear side of the correction baffle 2 and is tightened on the long baffle rear plate 4. At this time, the mounting bolt and the long baffle rear plate are screwed together. Of course, the mounting bolt can also be tightened on the long baffle rear plate. At this time, the mounting bolt and the correction baffle are screwed together.

[0026] To prevent the casting film from leaking out from the mounting groove, it is best that the highest point of the sponge pad 3 coincides with the highest point of the mounting groove 2-1, and the rear side of the sponge pad 3 is parallel to the front side of the mounting groove 2-1. To increase the volume of the casting box, the upper end of the long baffle rear plate is set to be tilted backward, that is, the long baffle rear plate is set to be tilted. At this time, the mounting groove 2-1 is set as an inclined groove, and the rear side of the sponge pad 3 is set as an inclined surface parallel to the mounting groove 2-1.

[0027] Preferably, a scraper clearance notch 2-2 for making way for the casting scraper 1 is provided at the front upper end of the correction baffle 2, and a conveying clearance notch 2-3 for making way for the conveyor line 6 is provided at the lower end of the correction baffle 2. A scraper close-fitting notch 3-1 for close-fitting with the casting scraper 1 is provided at the front upper end of the sponge pad 3, and a conveying close-fitting notch 3-2 for close-fitting with the conveyor line 6 is provided at the lower end of the sponge pad 3.

[0028] When the casting scraper 1 drops to the lowest point, the scraper-fitting recess 3-1 above the two sponge pads 3 just fits with the lower side of the scraper handle 1-2 of the casting scraper 1. At the same time, since the conveying-fitting recess 3-2 below the sponge pad 3 is in close contact with the conveying line 6, and the rear side surface 3-3 of the sponge pad is in close contact with the long baffle plate 4, the two sponge pads 3, the conveying line 6, the long baffle plate 4 and the casting scraper 1 form a square and tight box-shaped space, namely the casting box.

[0029] Preferably, the length of the scraper close to the notch 3-1 is greater than the diameter of the scraper handle 1-2, that is, the sponge pad can extend to the front of the scraper handle, thereby preventing the scraper from rising and causing the casting slurry to overflow.

[0030] In order to realize the installation between the sponge pad and the correction baffle, the sponge pad 3 and the corresponding correction baffle 2 are connected by bonding. The bonding method can be glued by super glue or Velcro.

[0031] To ensure the correcting effect of the correcting baffle, the correcting baffle 2 is made of metal. Preferably, the distance between the scraper surface 1-1 and the scraper handle 1-2 is twice the maximum thickness of the formed cast film.
