Regardless of whether preforms or granules are used as raw materials, materials are generally easily squeezed against each other during the feeding process, causing more and more materials to pile up together, which can easily cause blockage of subsequent feeding; 2. Usually, the feed port is an integrated through structure, which causes the material to fall too quickly, so that too much raw material enters the blow molding unit, which can also easily cause blockage.

[0023] The conveying component 2 is provided with a pulley 201, which is connected to each other by rollers, and the pulley 201 is rotatably connected to the inner wall of the first feeding section 1 through a rotating shaft. The outside of the pulley 201 is covered with a conveying belt 202, and the surface of the conveying belt 202 is glued with a spacer plate 203.

[0024] The anti-blocking drive assembly 6 includes a discharge turntable 601, a driven gear 602 and a driving gear 603. The discharge turntable 601 and the driven gear 602 are rotatably connected between the second feeding interval 5 and the third feeding interval 7 via a rotating shaft installed inside the driven gear 602. The driven gear 602 is meshedly connected with the driving gear 603. The driving gear 603 is rotatably connected to the cavity on the outer side of the third feeding interval 7 via a mounting frame.

[0025] In this embodiment, Figure 1 As shown, the first feeding interval 1, the second feeding interval 5 and the third feeding interval 7 are an integrated structure, and a funnel-shaped discharge port is provided at the top of the first feeding interval 1, and the discharge port is located at the front end of the conveying component 2 and at the same horizontal position therewith, and at the same time, the outer walls of the first feeding interval 1 and the third feeding interval 7 are provided with glass visual windows; the structural form of the discharge port at the top of the first feeding interval 1 plays a preliminary role in alleviating the effect of the material falling too fast, and the integrated upright structure of the differential transmission makes the first feeding interval 1, the second feeding interval 5 and the third feeding interval 7 distributed in a horizontal L shape, and the problem of material discharge too fast is alleviated by the conveying component 2 and the anti-blocking drive component 6.

[0026] In this embodiment, Figure 2 As shown, the output end of the servo motor 8 is connected to the pulley 201 on one side through a rotating shaft, and the conveyor belt 202 and the partition plate 203 form a transmission structure through the servo motor 8 and the pulley 201, and the partition plates 203 are distributed in a ring shape and at equal distances on the surface of the conveyor belt 202; when all the raw materials are placed at the discharge port at the top of the first feeding interval 1, they fall onto the surface of the front end of the conveyor belt 202, and the partition plate 203 can separate the materials into batches, and gradually pour them onto the surface of the push plate 3 below through the circumferential transmission structure of the conveyor belt 202, and the materials are pre-stored and accumulated in the cavity where the push plate 3 is located.

[0027] In this embodiment, Figure 1 and Figure 3 As shown, the first feeding interval 1 is provided with a through hole penetrating the hydraulic telescopic rod 4, and the push plate 3 forms a horizontal transmission structure above the second feeding interval 5 through the hydraulic telescopic rod 4; when the material is accumulated on the push plate 3, the hydraulic telescopic rod 4 is driven to push the push plate 3 to push the material to the inside of the second feeding interval 5. The structure of using the hydraulic telescopic rod 4 to drive the push plate 3 to reciprocate and push the material reserves a certain operating time for the lower discharge, effectively ensuring the smoothness of the lower discharge and reducing the problem of mutual squeezing caused by excessive materials.

[0028] In this embodiment, Figure 3 and Figure 4 As shown, the second feeding interval 5 is in the shape of a trapezoid that is wider at the top and narrower at the bottom, and the inner walls are all inclined surfaces, and the bottom of the second feeding interval 5 and the surface of the discharge turntable 601 are provided with through holes of the same specifications; the structural form of the second feeding interval 5 can effectively prevent materials from piling up or getting stuck inside it, and all of them can be discharged into the third feeding interval 7 from the through holes at its bottom.

[0029] In this embodiment, Figure 4As shown, the driving gear 603 and the driven gear 602 form a rotating structure through the servo motor 8, and the through holes on the surface of the discharge turntable 601 are in circular motion along the axis center of the discharge turntable 601 through the driving gear 603 and the driven gear 602; the third feeding interval 7 is the final discharge port connecting the subsequent blow molding unit and the front end feed port. On the basis of the first feeding interval 1 and the second feeding interval 5 above, the driving gear 603 is driven by the servo motor 8 to drive the driven gear 602 to rotate the discharge turntable 601, so that the through holes on its surface are in an intermittent discharge structure along the bottom of the second feeding interval 5, so that the materials enter the blow molding unit in an orderly manner.

[0030] The use method and advantages of the utility model: When the feeding hopper of the bottle blowing machine with the function of dispersing materials is used, the working process is as follows:

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, first, the staff pours the raw materials into the discharge port at the top of the first feeding interval 1, and the materials will fall into the surface of the front end of the conveyor belt 202 through the opening. Under the drive of the servo motor 8, the array pulleys 201 and the rollers drive the conveyor belt 202 to transmit, and the partition plate 203 is transmitted together with the conveyor belt 202. At the same time, the partition plate 203 can separate the falling materials in batches in the transmission structure. When it is transferred to a point above the push plate 3, the materials will all be dumped into the cavity where the push plate 3 is located. The push plate 3 is pushed by the hydraulic telescopic rod 4 to fall into the second feeding interval 5. The telescopic reciprocating structure is used to make the materials fall progressively, which has the effect of secondary relief of the falling of the materials. The material falls into the second feeding interval 5, and will fall into the third feeding interval 7 through the through hole at the bottom thereof, and will be sent to the rear end blow molding unit by the third feeding interval 7. At the same time, the servo motor 8 drives the active gear 603 to drive the driven gear 602 to rotate the discharge turntable 601, so that the through holes on its surface form an intermittent discharge structure along the bottom of the second feeding interval 5, which ultimately reduces the falling speed of the material. The problem of the material falling too fast is delayed through the layer-by-layer progressive and intermittent discharge structure, which greatly reduces the problem of the material accumulating inside the feed hopper and causing blockage, improves the smoothness and orderliness of the discharge inside the feed hopper, and can be observed through the external glass visual window during operation.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected.
