Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to a blanking device for producing polypropylene woven bags. Background Art

[0002] Polypropylene woven bags are packaging bags made primarily from polypropylene. Polypropylene is a thermoplastic resin with high strength, corrosion resistance, and abrasion resistance. They are typically made from polypropylene flat yarns through a weaving process.

[0003] At present, in the production of polypropylene woven bags, the blanking device is of vital importance. Traditional blanking devices often have the problem of inaccurate ingredients, resulting in unstable product quality. For example, simple funnel-type blanking makes it difficult to control the proportion of different raw materials, which easily causes differences in product performance. Moreover, uneven mixing of raw materials also affects product quality. In actual production, due to poor blanking and mixing, problems such as insufficient strength of woven bags and appearance defects often occur. Therefore, we proposed a blanking device for polypropylene woven bag production to solve the above problems. Utility Model Content

[0023] like Figure 3 As shown, a mixed material discharging pipe 12 is fixed at the bottom of the processing table 1, and the top opening of the mixed material discharging pipe 12 is connected to the discharge hole 2.

[0024] It is further explained that the raw materials falling from the discharge hole will be mixed in the mixing discharge pipe, and the mixed raw materials will be collected at the outlet of the mixing discharge pipe for subsequent polypropylene woven bag production process.

[0025] like Figure 2 As shown, a batching mechanism is provided in the discharge hole 2; the batching mechanism includes a rotating groove 3 opened on the inner wall of the discharge hole 2, a batching ball 4 is rotated on the inner wall of the rotating groove 3, and two counterweight grooves 5 are provided on the batching ball 4, and the two counterweight grooves 5 are symmetrically arranged on the batching ball 4, and a T-slot 6 is provided at the bottom of the processing table 1.

[0026] It is further explained that the batching balls 4 are made more stable during rotation, vibration and noise caused by imbalance are reduced, and the service life of the equipment is extended.

[0027] like Figure 1 As shown, the processing table 1 and the T-slot 6 are coaxially arranged.

[0028] It is further explained that the structure of the entire device is more regular, the force is more uniform, and the stability of the device is further improved.

[0029] It is further explained that the batching balls 4 are made more stable during rotation, vibration and noise caused by imbalance are reduced, and the service life of the equipment is extended.

[0030] like Figure 1 As shown, a plurality of feed holes 2 are distributed in a circular array around the T-slot 6;

[0031] Further explanation: multiple discharge holes 2 are distributed in a circular array around the T-slot, so that the raw materials dropped from different discharge holes 2 can enter the mixing discharge pipe 12 more evenly, which is beneficial to the rapid mixing of the raw materials and improves production efficiency.

[0032] like Figure 1 As shown, a motor 7 rotates in the T-slot 6, a driving bevel gear 8 is fixedly sleeved on the output shaft of the motor 7, a connecting shaft 9 is fixed on the ingredient ball 4, a connecting bevel gear 10 is fixedly sleeved on the connecting shaft 9, and the driving bevel gear 8 and multiple connecting bevel gears 10 are all meshed and connected.

[0033] It is further explained that the batching ball 4 in the batching mechanism can rotate in the rotating groove 3, and the motor 7 drives the driving bevel gear 8, and then drives multiple connected bevel gears 10 to rotate the batching ball 4, which can accurately control the feeding speed and proportion of different raw materials, achieve precise batching, and improve the stability of product quality.

[0036] The functional principle of this utility model can be explained through the following operation modes:

[0037] 1. Preparation

[0038] Clean the processing table 1, the discharge hole 2, the batching ball 4, the feed funnel 11 and the central mixing and discharging pipe 12 to ensure that there are no residual raw materials or impurities that affect the discharge and mixing effects.

[0039] 2. Add raw materials

[0040] Different raw materials are poured into the corresponding feeding funnel 11 respectively. Since the feeding funnel 11 and the discharge hole 2 are connected in the vertical direction, the raw materials can enter the discharge hole 2 smoothly.

[0041] 3. Starting device

[0042] When the motor 7 is turned on, the driving bevel gear 8 on the output shaft of the motor 7 starts to rotate, and the driving bevel gear 8 drives the multiple connecting bevel gears 10 meshed with it to rotate. The connecting bevel gears 10 drive the ingredient balls 4 to rotate in the rotating groove 3 through the connecting shaft 9.

[0043] 4. Adjust the feeding speed and ratio

[0044] By controlling the speed of the motor 7, the rotation speed of the batching ball 4 can be adjusted. The two counterweight grooves 5 on the batching ball 4 will affect the feeding speed and flow of the raw materials during the rotation process. According to production needs, observe the feeding situation of the raw materials and adjust the speed of the motor 7 in time to achieve the required raw material feeding ratio and speed.

[0045] 5. Collect the mixed raw materials

[0046] The raw materials dropped from the discharge hole 2 are mixed in the mixing discharge pipe 12 , and the mixed raw materials are collected at the outlet of the mixing discharge pipe 12 for use in the subsequent polypropylene woven bag production process.

[0047] 6. Shutdown device
