Description

Technical Field

[0001] This utility model relates to the field of toner bottle blow molding technology, specifically to a toner bottle blow molding device with rapid cooling capability. Background Technology

[0002] A toner bottle blow molding machine is a specialized piece of equipment used to produce plastic toner bottles. It employs a hollow blow molding process, in which molten plastic preforms (usually PE, PP, etc.) are placed in a mold, and high-pressure air is used to inflate them to fit the inner wall of the mold. After cooling, a hollow container is formed.

[0003] In existing toner bottle blow molding equipment, the fixed base and sealing cap are separate structures to facilitate the removal of blow-molded parts from the molding cavity. Cooling pipes are typically located on the inner walls of the fixed base and sealing cap, outside the molding cavity. When removing the blow-molded parts from the molding cavity, the fixed base and sealing cap must be repeatedly separated and re-closed. This can easily cause deformation at the connection points of the cooling pipes during separation due to deviations in the force direction or forceful disassembly, thus reducing the service life of the toner bottle blow molding cooling system and consequently affecting the production efficiency of toner bottle blow-molded parts. Therefore, it is necessary to design a toner bottle blow molding equipment with rapid cooling that can extend the service life of the cooling pipes at the connection points of the fixed base and sealing cap. Utility Model Content

[0004] The purpose of this invention is to provide a toner bottle blow molding device that can be rapidly cooled, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapidly cooling toner bottle blow molding device, comprising a fixed base and a sealing cap, characterized in that:

[0006] A sealing cover is installed on the upper side of the fixed base. The fixed base has an "L" shaped cross-section and a cavity is opened inside the fixed base. A molding cavity is opened on the side of the fixed base and the sealing cover that are in contact with each other. The cavity is located below the molding cavity, and the cavity and the molding cavity are not interconnected.

[0007] A fan is installed on the side of the fixed base away from the sealing cover, and a conveying pipe is installed at the output end of the fan. The conveying pipe passes through the fixed base and is inserted into the cavity.

[0008] Both the fixed base and the sealing cover are equipped with air supply mechanisms. The air supply mechanisms are distributed on the outside of the molding cavity, and the bottom of the air supply mechanisms communicates with the inside of the cavity.

[0009] A limiting mechanism is installed on the outside of the sealing cover.

[0010] Preferably, the air supply mechanism includes a flow cavity, and multiple flow cavities are formed inside the fixed base and the sealing cover. The multiple flow cavities are arranged in a circumferential array and are evenly distributed on the outside of the forming cavity. Multiple through holes are evenly formed on the upper part of the cavity, and the through holes connect the cavity with the interior of the flow cavity.

[0011] Preferably, a plurality of insertion tubes are evenly installed on the side of the fixed base near the sealing cover, the through hole is located on the lower side of the insertion tube, and a plurality of sleeve holes are evenly opened on the bottom of the sealing cover. The sleeve holes communicate with the inside of the flow cavity, and the diameter of the sleeve holes is smaller than the inner diameter of the flow cavity.

[0012] The positions of the sleeve and the insertion tube are matched, the outer diameter of the insertion tube is the same as the inner diameter of the sleeve, and the insertion tube is inserted inside the sleeve.

[0013] Preferably, a sealing ring is installed inside the sleeve hole, the inner diameter of the sealing ring is the same as the inner diameter of the insertion tube, and the bottom of the sealing ring is in contact with the top of the insertion tube.

[0014] Preferably, both the fixed base and the sealing cover have ventilation slots inside, the ventilation slots are located at the top of the flow chamber, and the tops of the multiple flow chambers communicate with the interior of the ventilation slots;

[0015] The fixed base has an exhaust trough on the side away from the sealing cover, and the exhaust trough passes through the fixed base and communicates with the inside of the insertion tube.

[0016] Preferably, the limiting mechanism includes connecting blocks, two of which are symmetrically installed on both sides of the sealing cover. Supporting bases are installed on both sides of the fixed base, with the supporting bases located below the connecting blocks.

[0017] Preferably, an electric push rod is installed at the bottom of the support base, a connecting block is installed at the output end of the electric push rod, a sliding strip is installed on the side of the connecting block near the fixed base, the sliding strip is inserted inside the positioning rail, and the positioning rail is fixedly installed on one side of the fixed base.

[0018] Preferably, the positioning track has a groove inside, and the groove has a "T" shaped structure, with the end of the sliding bar away from the connecting block slidably installed inside the groove.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: When the rapidly cooling toner bottle blow molding device is used, by evenly distributing the flow chamber on the outer wall of the molding cavity, the flow chamber corresponds to different areas of the molding cavity.

Therefore, when the rapidly cooling toner bottle blow molding device is used, it plays the role of efficiently delivering cold air into the flow chamber 701 while extending the service life of the air supply mechanism.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a blow molding device for toner bottles that can be cooled quickly, including a fixed base 1 and a sealing cap 2. The sealing cap 2 is installed on the upper side of the fixed base 1. The fixed base 1 has an "L" shaped cross section. A cavity 3 is opened inside the fixed base 1. A molding cavity 5 is opened on the side where the fixed base 1 and the sealing cap 2 are in contact with each other. The cavity 3 is located below the molding cavity 5, and the cavity 3 and the molding cavity 5 are not interconnected.

[0030] A fan 6 is installed on the side of the fixed base 1 away from the sealing cover 2. A conveying pipe 4 is installed at the output end of the fan 6. The conveying pipe 4 passes through the fixed base 1 and is inserted into the cavity 3.

[0031] In practice, by closing the fixed base 1 and the sealing cover 2, the material for blowing the toner bottle is placed into the molding cavity 5, and then air is blown into the material. The material expands and fits against the inner wall of the molding cavity 5. At the same time, the blower 6 will start working to send air into the cavity 3. The cold air inside the cavity 3 will be transported to the outer wall of the molding cavity 5 through the flow cavity 701, thereby reducing the temperature of the material surface and achieving a cooling effect.

[0032] Please see Figure 1 and Figure 4 Both the fixed base 1 and the sealing cover 2 are equipped with air supply mechanisms 7. The air supply mechanisms 7 are distributed on the outside of the molding cavity 5, and their bottoms communicate with the inside of the cavity 3. The air supply mechanism 7 includes a flow cavity 701. Multiple flow cavities 701 are formed inside the fixed base 1 and the sealing cover 2 and are arranged in a circumferential array. The multiple flow cavities 701 are evenly distributed on the outside of the molding cavity 5. Multiple through holes 706 are evenly formed on the upper part of the cavity 3, and the through holes 706 connect the cavity 3 with the inside of the flow cavities 701.

[0033] In practice, cold air is delivered into the flow cavity 701 through the through hole 706 on the cavity 3. Since the flow cavity 701 is evenly distributed on the outside of the molding cavity 5 and the air inside the flow cavity 701 is continuously delivered upward, the cold air absorbs the heat generated on the inner wall of the molding cavity 5 in the area corresponding to the flow cavity 701 while being delivered upward, thereby achieving the effect of cooling the inner wall of the molding cavity 5 and improving the cooling effect during the blow molding of toner bottles inside the molding cavity 5.

[0034] Please see Figures 3-5 Multiple insertion tubes 702 are evenly installed on the side of the fixed base 1 near the sealing cover 2. The through hole 706 is located on the lower side of the insertion tube 702. Multiple sleeve holes 704 are evenly opened at the bottom of the sealing cover 2. The sleeve holes 704 communicate with the inside of the flow cavity 701, and the diameter of the sleeve holes 704 is smaller than the inner diameter of the flow cavity 701.

[0035] The positions of the sleeve 704 and the insertion tube 702 are matched, the outer diameter of the insertion tube 702 is the same as the inner diameter of the sleeve 704, and the insertion tube 702 is inserted into the sleeve 704.

[0036] In practice, the cooperation between the sleeve hole 704 and the insertion tube 702 allows the sealing cover 2 to be lifted up and the toner bottle processed inside the molding cavity 5 to be taken out. This provides positioning and installation between the fixed base 1 and the sealing cover 2. The fixed base 1 and the sealing cover 2 can be reassembled simply by inserting the sleeve hole 704 into the insertion tube 702.

[0037] Please see Figure 4 A sealing ring 703 is installed inside the sleeve hole 704. The inner diameter of the sealing ring 703 is the same as the inner diameter of the insertion tube 702, and the bottom of the sealing ring 703 contacts the top of the insertion tube 702.

[0038] In practice, the cooperation between the sealing ring 703, the sleeve hole 704 and the insertion tube 702 can fill the gap between the insertion tube 702 and the sleeve hole 704 when cold air is delivered into the flow cavity 701 through the through hole 706, thereby reducing the leakage and dispersion of air from the gap and improving the efficiency of air delivery into the flow cavity 701.

[0039] Please see Figure 2 and Figure 6 Both the fixed base 1 and the sealing cover 2 have ventilation slots 705 inside. The ventilation slots 705 are located at the top of the flow chamber 701, and the tops of multiple flow chambers 701 are connected to the inside of the ventilation slots 705.

[0040] An exhaust duct 707 is provided on the side of the fixed base 1 away from the sealing cover 2. The exhaust duct 707 passes through the fixed base 1 and communicates with the interior of the insertion tube 702.

[0041] In practice, when cold air is delivered into the flow cavity 701 through the through hole 706, the air that has absorbed heat from the molding cavity 5 will be delivered into the ventilation slot 705 by the upward force and then discharged into the fixed base 1 and the sealing cover 2 through the exhaust slot 707 on one side of the ventilation slot 705. This ensures that the air inside the flow cavity 701 is always in a state of circulation, further improving the efficiency of cooling the heat adsorbed on the inner wall of the molding cavity 5 by the air circulation inside the flow cavity 701.

[0042] Please see Figure 2 and Figure 7 The limiting mechanism 8 includes a connecting block 804. Two connecting blocks 804 are symmetrically installed on both sides of the sealing cover 2. Support bases 805 are installed on both sides of the fixed base 1. The support bases 805 are located below the connecting blocks 804. An electric push rod 801 is installed at the bottom of the support base 805. A connecting block 804 is installed at the output end of the electric push rod 801. A sliding strip 806 is installed on the side of the connecting block 804 near the fixed base 1. The sliding strip 806 is inserted into the positioning rail 802. The positioning rail 802 is fixedly installed on one side of the fixed base 1.

[0043] In practice, through the cooperation between the electric push rod 801 and the connecting block 804, the sealing cap 2 can be gently lifted upward after the toner bottle inside the forming cavity 5 is processed, thereby separating the insertion tube 702 from the sleeve hole 704. This reduces the deformation of the sleeve hole 704 and the insertion tube 702 caused by the different force directions when lifting upward during the process of separating the fixed base 1 and the sealing cap 2, thus extending the service life of the air supply mechanism 7.

[0044] Please see Figure 7 The positioning track 802 has a groove 803 inside, and the groove 803 has a "T" shaped structure. The end of the sliding bar 806 away from the connecting block 804 is slidably installed inside the groove 803.

[0045] In practice, through the cooperation between the positioning rail 802, the slide groove 803 and the sliding bar 806, while the electric push rod 801 pushes the connecting block 804 to lift the sealing cover 2 upward, the sliding bar 806 is moved within the slide groove 803. The top of the positioning rail 802 is a closed structure, which limits the range of upward movement of the sliding bar 806 driven by the electric push rod 801.

[0046] In summary, when using this rapid-cooling toner bottle blow molding device, the fixed base 1 and sealing cap 2 are closed, the toner bottle blow molding material is placed into the molding cavity 5, and air is blown into the material. The material expands and adheres to the inner wall of the molding cavity 5. At the same time, the blower 6 starts working and blows air into the cavity 3. The cold air inside the cavity 3 is transported to the outer wall of the molding cavity 5 through the flow chamber 701, reducing the surface temperature of the material and achieving a cooling effect. This is existing technology and will not be elaborated further. By evenly distributing the flow chamber 701 on the outer wall of the molding cavity 5, so that the flow chamber 701 corresponds to different areas of the molding cavity 5, the cold air flows inside the flow chamber 701 during the toner bottle blow molding process, adsorbing the inner wall of the molding cavity 5. The heat generated during the blow molding of the toner bottle is cooled, and cold air is continuously and efficiently delivered into the cavity 3 by the fan 6, which increases the airflow efficiency inside the flow chamber 701 and thus achieves a rapid cooling effect. In addition, the sealing cap 2 is stably pushed upward by the electric push rod 801, which reduces the deformation of the sleeve hole 704 and the insertion tube 702 caused by the displacement of the moving direction of the sealing cap 2 when the blow-molded toner bottle is removed from the molding cavity 5, and extends the service life of the air supply mechanism 7. Thus, when using a toner bottle blow molding device with rapid cooling, it plays the role of efficiently delivering cold air into the flow chamber 701 while extending the service life of the air supply mechanism. The contents not described in detail in this description are prior art known to those skilled in the art.

[0047] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
