Description

Technical Field

[0001] This utility model relates to the field of blow molding equipment technology, and in particular to a blow molding device for edible plastic packaging bottles. Background Technology

[0002] Plastic bottles are mainly made of polyester, polyethylene, and polypropylene as raw materials. After adding appropriate organic solvents, they are heated at high temperatures and then formed into plastic containers through blow molding, extrusion blow molding, or injection molding using plastic molds. They are mainly used as disposable plastic packaging containers for liquids or solids such as beverages, food, pickles, and edible oils. During the processing of plastic bottles, the preform needs to be blow-formed to facilitate subsequent processing.

[0003] A known example of a blow molding device for edible plastic packaging bottles can be found in Chinese Utility Model Patent Publication No. CN215151729U, which discloses a blow molding device for plastic preforms. This device, belonging to the field of blow molding equipment technology, specifically comprises a mounting frame. An electric indexing plate is fixedly mounted on the top of the mounting frame, and a drive plate is fixedly mounted on the top of the electric indexing plate. Four sets of electric telescopic rods are fixedly mounted on the top of the drive plate, and forming templates are fixedly mounted on the output shafts of the electric telescopic rods. This blow molding device holds the preform inside two forming templates. The electric indexing plate drives the drive plate and forming templates to rotate, moving the forming templates containing the preforms to the bottom of the heating blow molding mechanism for blow molding. A photoelectric switch detects the position of the forming templates after blow molding, and the photoelectric switch feeds the signal back to the control box. The control box then controls the electric telescopic rods to open the forming templates, achieving material unloading and improving the degree of automation.

[0004] However, in actual use, it was found that after the plastic bottles were blow-molded, there would be excess blanks. These plastic bottles would need to be processed again, resulting in a waste of manpower and resources and increasing production costs. Therefore, this application provides a blow molding device for edible plastic packaging bottles to meet the needs. Utility Model Content

[0028] like Figure 1 and Figure 2 As shown, an embodiment of this utility model provides a blow molding device for edible plastic packaging bottles, including: a base 1, a blow molding machine 2 fixedly installed at one end of the top of the base 1, two symmetrical support plates 3 fixedly installed on the top of the base 1, hydraulic rods 4 installed on opposite sides of the two support plates 3, and a mold 5 fixedly installed at the other end of the hydraulic rods 4. The feature is that a slide assembly 6 is fixedly installed on the top of the base 1, a first support platform 7 and a second support platform 8 are fixedly installed on the top of the base 1 and on the same side of the slide assembly 6, a cleaning assembly 9 is fixedly installed on the top of the first support platform 7, and a lifting assembly 10 is fixedly installed on the top of the second support platform 8. A scraping assembly 11 is provided on the lifting assembly 10.

[0029] The scraping assembly 11 includes a body 111, a connecting piece 112 fixedly installed on the back of the body 111, a sliding groove 113 opened on the front of the body 111, a limiting rod 114 fixedly installed in the inner cavity of the body 111, a handle 115 slidably connected to the outer wall of the limiting rod 114, a cutting blade 116 fixedly installed at the front end of the handle 115, a spring 117 sleeved on the outer wall of the limiting rod 114, a limiting block 118 fixedly installed at the bottom of the inner wall of the body 111, and a groove adapted to the limiting block 118 opened at the bottom of the handle 115.

[0030] like Figure 1 and Figure 4As shown, the slide assembly 6 includes a housing 61. A first motor 62 is fixedly installed on the outer wall of one end of the housing 61. A first threaded rod 63 is fixedly installed on the output shaft of the first motor 62. A slider 64 is threadedly connected to the outer edge of the first threaded rod 63. A material plate 65 is fixedly installed on the top of the slider 64. A limit strip 66 is slidably connected to the bottom of the slider 64, and the limit strip 66 is fixedly connected to the bottom of the inner cavity of the housing 61. The first motor 62 drives the first threaded rod 63 to rotate, causing the slider 64 to move the material plate 65.

[0031] like Figure 1 and Figure 2 As shown, the cleaning component 9 includes a fixing plate 91, an electric telescopic rod 92 is fixedly installed on one side of the fixing plate 91, and a scraper 93 is fixedly installed at the front end of the electric telescopic rod 92.
