Description

Technical Field

[0001] The invention relates to the technical field of probiotic bottle production, and more particularly to a sealing method for a split-type bottled powder product. Background Art

[0002] Existing probiotic powder products are mainly packaged in strip bags, and there are some shortcomings in the strip bag packaging method: when consumers take it, the strip bag packaging is not easy to tear open, and the strip bag gap is small after tearing, which is not convenient to take. The easy-tear opening of the strip is serrated, which is difficult to tear open, and the tearing gap is incomplete, and the powder is not easy to pour out. The rounded packaging solves the problem of difficulty in tearing, but the gap is too small after tearing, which is also inconvenient to take. After research on the product, the use of bottled products can solve the above problems well. The probiotic bottle body is divided into two parts, namely, the bottle cap and the lower bottle body structure. The probiotic bottle cap has an upper bottle body under the conventional bottle cap, and is clamped between the upper bottle body and the lower bottle body. A sealing structure is provided at the clamping position, and the cover and the upper bottle body are integrally formed. When using, the sealing structure is first removed, and then the cover and the upper bottle body are separated by external force to complete a one-time take.

[0003] The existing probiotic powder strip bags are generally sealed with heat-sealing technology, which melts the plastic film by heating and forms a seal under the pressure of the mold. This technology can complete the sealing quickly and efficiently, and the cost is relatively low. However, the split bottle structure requires an aluminum foil seal at the split, and the powder is filled inward before sealing. Since the split bottle is generally made of plastic, such as PP bottles, which have static electricity, a small amount of fine powder will fly during the filling process of the material, and then adhere to the surface of the lower bottle mouth. After filling, the surface of the lower bottle mouth absorbs the fine powder in the powder, resulting in failure to effectively fuse the bottle mouth and the heat-sealing film (aluminum foil) when the PP bottle is heat-sealed, resulting in air leakage;

[0004] Due to the deviation of the bottle body and heat-sealing film materials when they are supplied, and the occasional instability that may occur during the operation of the equipment, the aluminum foil may occasionally deviate during sealing, and in severe cases, it may cause air leakage. Therefore, the existing sealing method is not suitable for the sealing of split-type bottled products, which may easily lead to poor sealing, moisture absorption and agglomeration of products, and other undesirable problems.

[0005] Therefore, how to provide a sealing method suitable for split-type bottled products is a problem that those skilled in the art need to solve urgently. Summary of the invention

[0006] Therefore, in order to solve the sealing problem of split-type bottled powder products, the present invention proposes a sealing method for split-type bottled powder products.

[0007] The technical solution of the present invention comprises the following steps:

[0008] S1. A stable high-intensity electric field is formed on the top of the filling bottle. The ions formed by the electric field ionize the air and neutralize the static electricity of the filling bottle.

[0009] S2. When preparing to fill, reduce the gap between the feeding nozzle and the filling bottle to reduce the dust splashing caused by the gap between the feeding;

[0010] S3. After the material is discharged from the discharge nozzle, dust splashing will occur. Negative pressure is formed at the discharge nozzle to remove the dust splashing during the filling.

[0011] S4. After filling, clean the dust on the edge of the bottle seal above the bottle;

[0012] S5, sealing film and filling bottle sealing positioning;

[0013] S6, sealing the positioned sealing film and the sealing position of the filling bottle.

[0014] According to the technical solution of the present invention, an ionization device and a high-voltage generator for generating ions are arranged above the filling bottle in S1.

[0015] According to the technical solution of the present invention, a fan is used in S1 to deliver the plasma to the surface of the filling bottle.

[0016] According to the technical solution of the present invention, in S2, the filling bottle moves upward to below the feeding nozzle, thereby reducing the gap between the two.

[0017] Or move the feeding nozzle downward to above the filling bottle to narrow the gap between the two.

[0018] According to the technical solution of the present invention, the above gap is 2±0.5 mm.

[0019] According to the technical solution of the present invention, a negative pressure fan is used at the discharge nozzle in S3 to generate negative pressure in the discharge nozzle area to suck away the splashing dust generated during the discharge process.

[0020] According to the technical solution of the present invention, the negative pressure generated is in the range of 50±5 Pa.

[0021] According to the technical solution of the present invention, in S4, a pressure of 100±10Pa is used to absorb dust from the sealing edge of the filling bottle.

[0022] According to the technical solution of the present invention, an electronic system is used in S5 to determine whether the sealing film is in place. If in place, the sealing film is aligned with the sealing of the filling bottle, and S6 is performed after the detection.

[0023] According to the technical solution of the present invention, S7 quality inspection is performed to remove unqualified seals.

[0024] It can be seen from the above technical solutions that, compared with the prior art, the present invention realizes an efficient and clean filling process while ensuring the sealing quality and reducing environmental pollution.

[0025] The present invention adopts static neutralization and dust control: by forming a stable high-strength electric field on the top of the filling bottle, the ions generated by ionized air are used to neutralize the static electricity of the filling bottle, effectively preventing the dust adsorption problem caused by static electricity. When the material is discharged from the discharge nozzle, a negative pressure fan is used to generate negative pressure in the filling nozzle area to absorb the splashing dust, further controlling the diffusion of dust.

[0026] The present invention reduces dust splashing during the filling process: by reducing the gap between the feeding nozzle and the filling bottle, dust splashing caused by too large a feeding gap is reduced, and the cleanliness of the filling process is improved. After filling, a suction device with a specific pressure is used to clean the dust on the sealing edge of the filling bottle to ensure the cleanliness of the sealing area and prevent dust from affecting the sealing quality.

[0027] The invention has precise sealing and quality assurance: the electronic system is used to determine whether the sealing film is in place and whether the sealing film is aligned with the filling bottle seal to ensure the accuracy and consistency of the seal. Quality inspection is carried out to remove unqualified seals to ensure the overall quality of the product.

[0028] The present invention takes into account the operation requirements under different environments, such as adjusting the relative positions of the filling bottle and the feeding nozzle to adapt to different production line layouts and operation conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Figure 1 The accompanying drawing is a schematic diagram of the process steps of a sealing method for a split-type bottled powder product provided by the present invention. DETAILED DESCRIPTION

[0030] The existing probiotic powder bag is generally sealed with heat sealing technology, which can complete the sealing quickly and efficiently. However, when filling powder in a split bottle and sealing it, it is necessary to set an aluminum foil seal at the split, and fill the powder inside before sealing. Since the split bottle is generally made of plastic, such as PP bottles, which have static electricity, a small amount of fine powder will splash during the filling process, and then adhere to the surface of the lower bottle mouth. After filling, the surface of the lower bottle mouth absorbs the fine powder in the powder, resulting in the failure of effective fusion between the bottle mouth and the heat sealing film (aluminum foil) when the PP bottle is heat-sealed, resulting in air leakage; therefore, the existing heat sealing technology cannot be directly used.

[0031] In addition, the deviation of the bottle body and sealing film materials themselves when they are received, and the instability that may occur during equipment operation may cause the sealing film aluminum foil to shift during sealing, and in severe cases, it may cause air leakage.

[0032] Therefore, the existing sealing method is not applicable to the sealing of split-type bottled powder products, which may easily lead to problems such as poor sealing performance, moisture absorption and agglomeration of the product, etc.

[0033] In view of this, see Appendix Figure 1 The technical solution of the present invention adopts a sealing method for a split-type bottled powder product, which specifically includes the following steps:

[0034] S1. A stable high-intensity electric field is formed on the top of the filling bottle. The ions formed by the electric field ionizing the air neutralize the static electricity of the filling bottle. Specifically, an ionizing device and a high-voltage generator generating ions are arranged above the filling bottle, and a fan is used to deliver the ions to the surface of the filling bottle. The fan can be connected to a nozzle, and the nozzle is 4±0.5cm above the filling bottle.

[0035] When the high voltage generated by the high voltage generator is applied to the ionization device, the molecules in the air or other gas medium around the ionization device are ionized to form positive and negative ions. These ions begin to move under the action of the electric field to form a plasma. The speed and direction of the plasma depends on the strength and configuration of the electric field.

[0036] S2. When preparing to fill, the gap between the feeding nozzle and the filling bottle is reduced to reduce the dust splashing caused by the gap between the feeding; in S2, the filling bottle moves upward to the bottom of the feeding nozzle to reduce the gap between the two. In this solution, the bottom of the filling bottle can have a lifting mechanism;

[0037] Or the feed nozzle is moved downward to above the filling bottle to reduce the gap between the two. In this solution, the upper part of the feed nozzle is provided with a retractable mechanism.

[0038] Both solutions ensure that the above gap is 2±0.5mm.

[0039] S3, after the material is discharged from the discharge nozzle, dust splashing will be generated, and negative pressure will be formed at the discharge nozzle to remove the dust splashing during the filling process; in S3, a negative pressure fan is used at the discharge nozzle to generate negative pressure in the discharge nozzle area to suck away the splashing dust generated during the discharge process. Here, a suction component such as a tube body can be set at the discharge nozzle, and the tube body is connected to the negative pressure fan, and the negative pressure range generated is 50±5pa to suck away the splashing dust generated during the discharge process.

[0040] S4, after filling, clean the dust on the edge of the bottle seal above the filling bottle; in S4, the dust on the edge of the bottle seal is sucked at a pressure of 100±10Pa. The specific pressure source can be a powder suction mechanism, the suction end of the powder suction mechanism corresponds to the seal of the filling bottle after filling, and then the instantaneous production line negative pressure of the powder suction mechanism is used to suck all the dust blown out in the previous beat.

[0041] S5, positioning the sealing film and the sealing of the filling bottle; in S5, an electronic system is used to determine whether the sealing film is in place, and if so, whether the sealing film and the sealing of the filling bottle are aligned, and then S6 is performed.

[0042] For the above solution, a photoelectric eye can be placed about 10±1cm above the filling bottle. If there is no sealing film placed above the filling bottle, the photoelectric eye generates a current signal to the industrial control system of the equipment, and the industrial control system gives a signal to control the action of the heat sealing head and not to perform heat sealing. This detection can effectively eliminate the situation of no film caused by fluctuations in the production site, avoid contamination of the heat sealing head and loss of packaging materials caused by heat sealing without film, and ensure that the sealing film corresponds to the position of the filling bottle, prevent the deviation of the bottle body and the sealing film when the material is incoming, and the occasional instability that may occur during the operation of the equipment may cause the aluminum foil to occasionally deviate during sealing, and in severe cases, cause air leakage.

[0043] S6, sealing the positioned sealing film and the sealing position of the filling bottle.

[0044] S7 quality inspection can eliminate unqualified seals by using visual inspection. Through deep visual learning, all qualified and abnormal samples are entered into the visual system in advance. During the batch production process, the camera directly above the filling bottle will take a picture of the sealed product and compare it with the system information to determine whether the seal meets the requirements and eliminate unqualified seals.

[0045] The present invention achieves static neutralization, dust control, precise sealing and quality assurance during the filling process through a series of innovative measures, thereby improving production efficiency and product quality while reducing environmental pollution. These technical effects are of great significance for the sealing of split-bottle powder products. The present invention is not only suitable for the sealing of split-bottle probiotic powder, but also suitable for the sealing of other split-bottle powder products.

[0046] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
