Description

Technical Field

[0001] The present invention relates to the technical field of plastic bottle molding, and in particular to intelligent molding equipment and a method for processing pesticide plastic bottles. Background Art

[0002] When molding pesticide plastic bottles, the plastic bottle raw materials are usually first transported into the seat body through the feed pipe, and a parison is formed after being discharged from the seat body. Then, the parison is transferred to the blow molding station through the transfer mechanism. After the blow molding is completed, it is transferred to the conveying station, and the molded pesticide plastic bottle is transferred away for subsequent capping and filling and other processing. Finally, the transfer mechanism is moved to the parison again, and this cycle is repeated to complete the automated molding of the pesticide plastic bottle.

[0003] Publication number CN112693099B discloses a plastic bottle manufacturing device that integrates heating and blowing molding. The problem raised in its background technology is that before blow molding, the plastic bottle needs to be manually heated and softened. After the softening, the plastic bottle needs to be manually taken out and placed on the blower to blow the softened plastic bottle. If there is a problem in a part of the bottle, the entire bottle needs to be re-injected. During this process, the plastic bottle needs to be manually moved multiple times, which makes it inefficient and is more likely to hurt the hands.

[0004] Based on the existing technology, the following problems exist: The existing plastic bottle compression molding equipment only produces the preform by continuously squeezing the plastic bottle raw material into the preform forming device during the process of forming the preform, which easily leads to uneven distribution of the plastic bottle raw material and is not convenient for quickly forming the preform, resulting in the preform drooping too long, resulting in uneven distribution of the plastic bottle raw material of the preform. In addition, during the formation process of the preform, the inner wall of the preform is prone to adhesion, which affects the stability of the subsequent blow molding and the quality of the pesticide plastic bottle molding. There are certain shortcomings. In order to solve the above problems, an intelligent compression molding equipment and method based on pesticide plastic bottle processing are proposed.

[0010] Furthermore, the auxiliary mechanism further includes: The connecting head is rotatably mounted on the top of the connecting seat and extends into the sleeve rod; The liquid guide tube is sleeved in the sleeve rod and extends to the top of the connecting plate.

[0015] The present invention provides an intelligent die-casting device and method for processing pesticide plastic bottles. Compared with the existing technology, it has the following advantages: 1. The present invention rotates the second guide block, the first guide rod and the second guide block through a rotating mechanism, thereby increasing the fluidity of the plastic bottle raw material in the guide cavity, so that the plastic bottle raw material is more evenly distributed in the guide cavity, thereby improving the uniformity of subsequent preforms. The auxiliary mechanism reduces adhesion between the inner walls of the preforms and increases the buoyancy of the preforms in the air, thereby reducing the uneven distribution of the plastic bottle raw material in the preforms due to excessive downward drooping of the preforms after extrusion, thereby improving the quality of pesticide plastic bottles.

[0016] 2. The present invention enables the spiral blades to convey the plastic bottle raw materials downward, thereby increasing the fluidity of the plastic bottle raw materials and making the plastic bottle raw materials more compact. It also avoids the traditional situation in which the raw materials in the guide cavity are squeezed by continuously conveying the plastic bottle raw materials, resulting in slow discharge of the plastic bottle raw materials. It increases the speed of forming the preform, is conducive to improving work efficiency, and avoids the situation in which the preform is suspended at the bottom of the guide tube for too long and causes the preform to be deformed.

[0017] 3. The present invention rotatably connects the second guide rod to the second guide block and limits the second guide rod through an auxiliary mechanism so that it does not rotate with the first guide rod. This allows the plastic bottle raw materials to be evenly distributed through the molding mechanism, while not affecting the stability of the plastic bottle raw materials being discharged through the guide tube and the second guide rod.

[0018] 4. The present invention discharges the preform through the guide tube and the second guide rod and continuously moves downward when the lubricating oil is sprayed, so that the lubricating oil can fully contact the inner wall of the preform. By providing a first valve body and a second valve body, etc., it is convenient to separately control the air guide tube and the liquid guide tube. When the lubricating oil is evenly sprayed in the preform but there is insufficient gas, the gas is sprayed into the preform through the nozzle to make the preform reach the specified buoyancy, thereby avoiding the injection of excessive lubricating oil and reducing the uneven distribution of plastic bottle raw materials caused by the drooping process of the preform.

[0019] 5. The present invention uses a sliding mechanism to enable the rotating mechanism to drive the sleeve rod to rotate, while the lifting mechanism can adjust the height of the sleeve rod, which is convenient for actual adjustment and use, and convenient for adjusting the height position of the nozzle, so as to facilitate the rapid and uniform gas flow in the parison, and is convenient for use with some large parisons; By adjusting the number of transmission gears in the transmission mechanism, multiple connecting pipes can be synchronously transmitted. By adjusting the length of the connecting plate, the height of multiple sleeve rods can be synchronously adjusted, so that adjustment can be made according to the number of synchronously discharged blanks. This makes it suitable for use in multi-station molding equipment such as double-station molding equipment, thereby improving molding efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Embodiment one: please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , an intelligent compression mold equipment based on pesticide plastic bottle processing, comprising a seat body 1 and a feeding pipe 2 designed in a bent shape. When the pesticide plastic bottle is formed, the plastic bottle raw material is usually first conveyed to the seat body 1 through the feeding pipe 2, and a parison is formed after being discharged from the seat body 1. Then, the parison is transferred to a blow molding station by a transfer mechanism, and after blow molding, it is transferred to a conveying station. The formed pesticide plastic bottle is transferred away for subsequent cap covering and filling treatment. Finally, the transfer mechanism is moved to the parison again to circulate, so as to complete the automatic forming of the pesticide plastic bottle. This is the prior art, which will not be described here. It also includes a guide cavity 4 spaced apart in the seat body 1 and a forming mechanism 3 arranged in the guide cavity 4 for guiding the plastic bottle raw material to form a parison. The forming mechanism 3 comprises: The first guide rod 32 is sleeved in the guide cavity 4, and the top and bottom of the first guide rod 32 are fixed with a first guide block 31 and a second guide block 33 respectively, and the first guide block 31 and the second guide block 33 are designed in a truncated cone shape and an inverted truncated cone shape respectively. The inner wall of the guide cavity 4 is adapted to the side walls of the first guide rod 32, the first guide block 31 and the second guide block 33. The top of the base body 1 is provided with a rotating mechanism 9 for driving the first guide rod 32 to rotate, and the interior of the forming mechanism 3 is provided with a sleeve rod 11 for lifting. The bottom of the sleeve rod 11 is provided with an auxiliary mechanism 12 along the inside of the sleeve rod 11 and extending to the top of the sleeve rod 11, and the top of the base body 1 is provided with a lifting mechanism 8 for driving the sleeve rod 11 to rise and fall.

[0024] During specific implementation, after the plastic bottle raw material enters the guide cavity 4 between the feed pipe 2 and the connecting pipe 13, it is distributed in the gaps between the first guide block 31, the second guide block 33, the first guide rod 32 and the guide cavity 4. By continuously conveying the plastic bottle raw material, the plastic bottle raw material in the gap is squeezed downward, so that the plastic bottle raw material is discharged between the second guide rod 6 and the guide pipe 5 and forms a parison, which facilitates the subsequent production of pesticide plastic bottles by blow molding.

[0025] The first guide block 31 facilitates the even distribution of the plastic bottle raw materials discharged from the feed pipe 2 to the side wall of the first guide rod 32 , and the second guide block 33 allows the plastic bottle raw materials to flow downward while being introduced into the guide pipe 5 , so that the parison is formed more evenly.

[0026] See also Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 10 , a guide tube 5 is fixedly provided at the bottom of the seat body 1, and the inner wall of the guide tube 5 is connected to the inner wall of the guide cavity 4; The bottom of the second guide block 33 is rotatably provided with a second guide rod 6 extending into the guide tube 5. The central axes of the first guide rod 32, the second guide rod 6, the first guide block 31 and the second guide block 33 coincide with each other, and all coincide with the central axes of the guide tube 5 and the guide cavity 4. The connecting seat 121 is located at the bottom of the guide tube 5. The first guide block 31, the first guide rod 32, the second guide rod 6 and the second guide block 33 are all hollow in design, and the side wall diameter of the connecting seat 121 is smaller than the outer wall diameter of the second guide rod 6.

[0027] A connecting tube 13 extending to the top of the feed tube 2 is fixedly provided on the top of the first guide block 31, and the connecting tube 13 is rotatably connected to the feed tube 2. The side wall diameter of the connecting tube 13 is smaller than the inner wall diameter of the feed tube 2, so that there is space between the connecting tube 13 and the feed tube 2 for the plastic bottle raw material to flow; The lower end of the outer wall of the first guide rod 32 is fixedly sleeved with a spiral blade 7, so that when the first guide rod 32 rotates, the spiral blade 7 pushes the plastic bottle material in the guide cavity 4 to flow downward. The rotating mechanism 9 includes: The servo motor 91 is fixed on the top of the base body 1 , and a transmission mechanism 92 is provided on the outer wall of one end of the connecting tube 13 located at the top of the feeding tube 2 so that the servo motor 91 drives the spaced connecting tubes 13 to rotate synchronously through the transmission mechanism 92 .

[0028] During the specific implementation, the servo motor 91 is started, and the servo motor 91 drives the connecting tube 13 to rotate through the transmission mechanism 92, thereby driving the second guide block 33, the first guide rod 32 and the second guide block 33 to rotate. As a result, after the plastic bottle raw material enters the guide cavity 4, the fluidity of the plastic bottle raw material is increased, so that the plastic bottle raw material is more evenly distributed in the guide cavity 4, thereby improving the uniformity of the subsequent parison, thereby improving the quality of the pesticide plastic bottle; By setting the spiral blade 7, when the first guide rod 32 rotates, the spiral blade 7 has the effect of conveying the plastic bottle raw material downward, thereby increasing the fluidity of the plastic bottle raw material, making the plastic bottle raw material more compact, and avoiding the traditional method of only continuously conveying the plastic bottle raw material to squeeze the raw material in the guide cavity 4 so that the plastic bottle raw material is discharged from the guide tube 5, causing the plastic bottle raw material to be discharged slowly, thereby increasing the speed of forming the preform, which is beneficial to improving work efficiency and avoiding the preform being suspended at the bottom of the guide tube 5 for too long and causing the preform to be deformed.

[0029] By rotatably connecting the second guide rod 6 to the second guide block 33 and limiting the second guide rod 6 by the auxiliary mechanism 12, the second guide rod 6 does not rotate with the first guide rod 32, thereby evenly distributing the plastic bottle raw materials through the molding mechanism 3 and the like, while not affecting the stability of the plastic bottle raw materials discharged through the guide tube 5 and the second guide rod 6.

[0030] The transmission mechanism 92 includes a transmission gear, a chain and a rotating shaft. The rotating shaft is fixed to the output shaft of the servo motor 91 through a coupling. The transmission gear is fixedly sleeved on the outer wall of one end of the connecting tube 13 located at the top of the feed tube 2 and the side wall of the rotating shaft. The chain is engaged with the transmission gear, thereby synchronously driving the spaced connecting tubes 13 and the first guide rod 32 to rotate through the servo motor 91.

[0031] Example 2: Please refer to Figure 12 、 Figure 13 、 Figure 14 、 Figure 15 、 Figure 16 、 Figure 17 and Figure 18 The difference between this embodiment and the first embodiment is that the auxiliary mechanism 12 includes: The connecting seat 121 is fixedly mounted on the bottom of the sleeve rod 11 . The sidewall of the connecting seat 121 is embedded with nozzles 129 arranged in a circular array to spray lubricating oil and gas into the preform.

[0032] The auxiliary mechanism 12 further includes: The connector 1292 is rotatably mounted on the top of the connector base 121 and extends into the sleeve rod 11; The liquid guide tube 124 is sleeved in the sleeve rod 11 and extends to the top of the connecting plate 82. The discharge end of the liquid guide tube 124 is connected to the liquid inlet end of the connecting head 1292, and the discharge end of the connecting head 1292 is connected to the liquid inlet end of the nozzle 129 to transport lubricating oil to the nozzle 129.

[0033] The auxiliary mechanism 12 further includes: The air guide tube 127 is sleeved in the sleeve rod 11 and extends to the top of the connecting plate 82. The exhaust end of the air guide tube 127 is fixed with a bend pipe 1291. The exhaust end of the bend pipe 1291 is connected to the liquid guide tube 124. The outer wall of the bend pipe 1291 is provided with a first one-way valve 1293 and a first valve body 125. The outer wall of one end of the liquid guide tube 124 located at the top of the bend pipe 1291 is provided with a second one-way valve 122 and a second valve body 123. The bottom of the air guide tube 127 is rotatably connected to the top of the connecting head 1292.

[0034] The auxiliary mechanism 12 further includes: The fixing rod 126 is fixed to the top of the connecting plate 82 and extends along the inner wall of the sleeve rod 11 to the bottom of the connecting seat 121; The first limiting rod 1294 is fixed on the side wall of one end of the fixing rod 126 at the bottom of the connecting seat 121, and is arranged in a circular array. The first limiting rod 1294 is designed to be bent. The top of the first limiting rod 1294 is fixed with a second limiting rod 128 extending into the second guide rod 6. The bottom of the second guide rod 6 is provided with a limiting groove for sleeved with the second limiting rod 128. The top of the second limiting rod 128 is designed to protrude outward to limit the second limiting rod 128 from being separated from the limiting groove.

[0035] In specific implementation, during the process of forming the preform, the gas pipeline and the lubricating oil pipeline are respectively connected to the outside through the air guide tube 127 and the liquid guide tube 124, so that the gas and lubricating oil are mixed and sprayed into the preform through the nozzle 129 to reduce the adhesion between the inner walls of the preform, and by filling with gas, the buoyancy of the preform in the air is increased to reduce the uneven distribution of the plastic bottle raw material of the preform due to the excessive downward drooping after the preform is extruded from between the second guide rod 6 and the guide tube 5, so as to avoid affecting the quality of the pesticide plastic bottle.

[0036] After the air guide tube 127 and the liquid guide tube 124 are respectively connected to the gas pipeline and the lubricating oil pipeline, the first valve body 125 and the second valve body 123 are opened, and the gas enters the elbow 1291 through the air guide tube 127 and enters the liquid guide tube 124 through the elbow 1291. At the same time, the lubricating oil enters the connector 1292 through the liquid guide tube 124. Under the action of the first one-way valve 1293 and the second one-way valve 122, the gas and the lubricating oil are mixed and sprayed into the preform through the nozzle 129 to reduce the adhesion between the inner walls of the preform, and reduce the uneven distribution of the plastic bottle raw materials of the preform due to the excessive downward drooping after the preform is extruded from between the second guide rod 6 and the guide tube 5, so as to avoid affecting the quality of the pesticide plastic bottle. By mixing the gas and the lubricating oil and then discharging them into the preform, the uniformity of the distribution of the lubricating oil is improved, thereby improving the effect of reducing the adhesion of the inner wall of the preform.

[0037] When the lubricating oil is sprayed, the parison is discharged through the guide tube 5 and the second guide rod 6 and continuously moves downward, so that the lubricating oil can fully contact the inner wall of the parison. Since the side wall diameter of the connecting seat 121 is smaller than the outer wall diameter of the second guide rod 6, the lubricating oil and gas can be sprayed without affecting the formation of the parison.

[0038] By setting the first valve body 125 and the second valve body 123, etc., it is convenient to separately control the air guide tube 127 and the liquid guide tube 124. When the lubricating oil is evenly sprayed into the preform but there is insufficient gas, the second valve body 123 is closed, and the gas is sprayed into the preform through the nozzle 129 to make the preform reach the specified buoyancy, thereby avoiding excessive injection of lubricating oil and reducing the uneven distribution of plastic bottle raw materials due to the drooping process of the preform.

[0039] The connector 1292 is a rotary joint for practical use. This is prior art and will not be described in detail here.

[0040] The lower end of the inner side wall of the second guide rod 6 is fixedly sleeved with spaced sealing rings to provide dynamic sealing between the second guide rod 6 and the sleeve rod 11; The length of the sleeve rod 11 at the top of the connecting tube 13 is adapted to the distance the second limiting rod 128 moves in the limiting groove, so that when the sleeve rod 11 is raised or lowered, the second limiting rod 128 can always limit the second guide rod 6 and prevent the second guide rod 6 from rotating.

[0041] The outer wall of the sleeve rod 11 is provided with a sliding mechanism 10 for limiting the sleeve rod 11 .

[0042] See also Figure 8 , the sliding mechanism 10 includes: The spline grooves 102 are formed in an annular array and are provided on the inner walls of the first guide rod 32 and the second guide block 33; The spline protrusions 101 are fixedly arranged on the outer wall of the sleeve rod 11 in an annular array and are sleeved in the spline groove 102, so that the sleeve rod 11 can move vertically along the inner wall of the spline groove 102, and the first guide rod 32 can drive the sleeve rod 11 to rotate.

[0043] See also Figure 8 、 Figure 9 and Figure 11 , the lifting mechanism 8 includes: The connecting plate 82 is provided on the top of the base body 1 and is T-shaped. The bottom of the connecting plate 82 is rotatably connected to the top of the sleeve rod 11. The electric push rod 81 is fixed on the back of the base body 1. The top of the telescopic shaft of the electric push rod 81 is fixedly connected to the bottom of the connecting plate 82. The bottom of the connecting plate 82 is fixed with a guide rod 83 extending into the base body 1, and the top of the base body 1 is provided with a guide groove for sleeved with the guide rod 83 to limit the lifting and lowering of the connecting plate 82.

[0044] During specific implementation, the spline groove 102 and the spline ridge 101 of the sliding mechanism 10 limit the position between the sleeve rod 11 and the first guide rod 32 and the second guide block 33, so that the sleeve rod 11 can move vertically relative to the first guide rod 32 and the second guide block 33. At the same time, the first guide rod 32 can drive the sleeve rod 11 to rotate, thereby driving the nozzle 129 to rotate, so that the nozzle 129 can spray the lubricating oil evenly on the inner wall of the preform, and by enabling the nozzle 129 to move vertically, it is convenient to adjust the height position of the nozzle 129. When only gas is delivered to the preform, by adjusting the height of the nozzle 129, it is convenient to make the gas in the preform quickly and evenly, which is convenient for use with some large preforms. After the gas is evenly distributed, the nozzle 129 is reset to avoid affecting the subsequent transfer of the preform.

[0045] When the nozzle 129 rotates, the first guide rod 32 rotates under the action of the rotating assembly, thereby causing the sleeve rod 11 to rotate under the action of the sliding mechanism 10, and the sleeve rod 11 is rotationally connected to the connecting plate 82, which does not affect the rotation of the sleeve rod 11 and does not affect the vertical movement of the sleeve driven by the lifting mechanism 8. When the sleeve rod 11 is lifted or lowered, the connecting plate 82 is driven to move by the electric push rod 81, thereby driving the sleeve rod 11 to move to adjust the height of the nozzle 129.

[0046] The transmission mechanism 92 facilitates synchronous transmission of multiple connecting tubes 13, and by adjusting the length of the connecting plate 82, the height of multiple sleeve rods 11 can be synchronously adjusted, so as to adjust the number of discharged parisons according to actual needs, so as to facilitate actual processing and use.

[0047] The embodiment of the present invention further provides a method for using an intelligent molding device for processing pesticide plastic bottles. The method comprises the following steps: S1: The plastic bottle raw material enters the guide cavity 4 through the space between the feed pipe 2 and the connecting pipe 13, and the molding mechanism 3 cooperates with the guide cavity 4 to form a parison after being extruded between the second guide rod 6 and the guide pipe 5; S2: During the formation of the preform, gas and lubricating oil are filled into the preform through the auxiliary mechanism 12 to assist the molding of the preform. By filling the preform with gas and lubricating oil, the adhesion between the inner walls of the preform is reduced during the subsequent transfer and final molding of the preform into a pesticide plastic bottle after formation. The buoyancy of the preform in the air is increased by filling with gas, so as to reduce the uneven distribution of the plastic bottle raw material of the preform due to the excessive downward drooping after the preform is extruded from between the second guide rod 6 and the guide tube 5, thereby avoiding affecting the quality of the pesticide plastic bottle.

[0048] The molding mechanism 3 is rotated by the molding mechanism 3 and the driving mechanism, so that the plastic bottle raw materials are evenly distributed in the guide cavity 4 , thereby improving the uniformity of the plastic bottle raw materials after they are discharged from the guide pipe 5 .
