TECHNICAL FIELD
[0001] The present application relates to the technical field of plastic bottle forming, in particular to an intelligent compression molding equipment and method based on pesticide plastic bottle processing. BACKGROUND
[0002] When forming pesticide plastic bottles, the plastic bottle raw material is usually first conveyed into the seat through the feeding pipe, and the parison is formed after being discharged from the seat. Then, the parison is transferred to the blow molding station by the transfer mechanism, and after blow molding, it is transferred to the conveying station. The formed pesticide plastic bottles are transferred for subsequent cap filling and other treatments. Finally, the transfer mechanism moves to the parison again to complete the automatic forming of the pesticide plastic bottles.
[0003] The background technology of the disclosure No. CN112693099B discloses a plastic bottle manufacturing device integrating heating and air forming. The problem is that the plastic bottle needs to be manually heated and softened before blow molding, and the softened plastic bottle needs to be manually taken out and placed on the air blower for air blowing. If the bottle has a problem in some positions, the entire bottle needs to be re-injected. In this process, the plastic bottle needs to be manually moved multiple times, which is low in efficiency and easy to injure the hand.
[0004] Based on the existing technology, the following problems exist:
[0005] The existing plastic bottle compression molding equipment only continuously extrudes the plastic bottle raw material into the parison forming device to form the parison during the parison forming process, which easily leads to uneven distribution of the plastic bottle raw material and is not convenient for quickly forming the parison. The excessively long downward sagging of the parison leads to uneven distribution of the plastic bottle raw material in the parison. In addition, the inner wall of the parison is prone to adhesion during the forming process, which affects the stability of the subsequent blow molding and the quality of the pesticide plastic bottle forming.

[0030] The application also provides a use method of the intelligent compression mold equipment based on pesticide plastic bottle processing.
[0031] S1: The plastic bottle raw material enters the guide cavity through the feeding pipe, and is formed into a parison after being extruded between the second guide rod and the guide pipe through the cooperation of the molding mechanism and the guide cavity.
[0032] S2: In the process of forming the parison, the auxiliary mechanism fills gas and lubricating oil into the parison to assist the molding of the parison.
[0033] The application provides an intelligent compression mold equipment and method based on pesticide plastic bottle processing.
[0034] 1: The second guide block, the first guide rod and the second guide block are rotated by the rotating mechanism, the flowability of the plastic bottle raw material in the guide cavity is increased, the plastic bottle raw material is more uniformly distributed in the guide cavity, the uniformity of the subsequent parison is improved, the adhesion between the inner walls of the parison is reduced by the auxiliary mechanism, the buoyancy of the parison in the air is increased, the distribution of the plastic bottle raw material of the parison after extrusion is not uniform due to the excessive length of the downward sag, and the quality of the pesticide plastic bottle is improved.
[0035] 2: The spiral blade has the effect of downwardly conveying the plastic bottle raw material, thereby increasing the flowability of the plastic bottle raw material, making the plastic bottle raw material more compact, avoiding the situation that the plastic bottle raw material is slowly extruded from the guide cavity by the traditional continuous conveying of the plastic bottle raw material, thereby improving the speed of forming the parison, being beneficial to improving the work efficiency, and avoiding the situation that the parison is suspended for a long time at the bottom of the guide pipe and deforms.
[0036] 3: The second guide rod is rotationally connected with the second guide block, and the second guide rod is limited by the auxiliary mechanism so as not to rotate with the first guide rod, so that the plastic bottle raw material is uniformly distributed by the molding mechanism, and the stability of the plastic bottle raw material extruded from the guide pipe and the second guide rod is not affected.
[0037] 4. In this invention, when lubricating oil is sprayed in, the preform is discharged through the guide pipe and the second guide rod and moves downward continuously, so that the lubricating oil can fully contact the inner wall of the preform. Furthermore, by setting the first valve body and the second valve body, it is easy to control the gas guide pipe and the liquid guide pipe separately. When lubricating oil is sprayed evenly into the preform but the gas is insufficient, the gas is sprayed into the preform through the nozzle to make the preform reach the specified buoyancy. This avoids spraying too much lubricating oil and reduces the uneven distribution of plastic bottle raw materials caused by the preform drooping process.
[0038] 5. The present invention enables the rotating mechanism to drive the sleeve rod to rotate through the sliding mechanism, while the lifting mechanism can adjust the height of the sleeve rod, which is convenient for actual adjustment and use, and also convenient for adjusting the height position of the nozzle, thereby facilitating the rapid and uniform gas distribution inside the blank, which is convenient for use in some large blanks.
[0039] By adjusting the number of transmission gears in the transmission mechanism, multiple connecting pipes can be driven synchronously. By adjusting the length of the connecting plate, the height of multiple sleeve rods can be adjusted synchronously, so as to adjust according to the number of blanks discharged synchronously. This makes it suitable for use in multi-station forming equipment such as dual-station equipment, thereby improving forming efficiency. Attached Figure Description

[0074] In specific implementation, the servo motor 91 is started, the servo motor 91 drives the connecting pipe 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, so that the flowability of the plastic bottle raw materials is increased after the plastic bottle raw materials enter the guide cavity 4, so that the plastic bottle raw materials are more evenly distributed in the guide cavity 4, so as to improve the uniformity of the subsequent parison, and further improve the quality of the pesticide plastic bottle;
[0075] 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 flowability of the plastic bottle raw material, making the plastic bottle raw material more compact, and avoiding the traditional situation of only continuously conveying the plastic bottle raw material to extrude the raw material in the guide cavity 4, so that the plastic bottle raw material is discharged from the guide pipe 5, causing the plastic bottle raw material to be discharged slowly, thereby improving the speed of forming the parison, which is beneficial to improve the work efficiency, and avoiding the situation that the parison is suspended at the bottom of the guide pipe 5 for too long time and the parison is deformed.

[0078] Embodiment two: please refer to Figure 12 、 Figure 13 、 Figure 14 、 Figure 15 、 Figure 16 、 Figure 17 and Figure 18 The difference between the technical scheme of the embodiment and the embodiment one is that the auxiliary mechanism 12 includes:
[0079] The connecting seat 121 is fixedly arranged at the bottom of the sleeve rod 11. The side wall of the connecting seat 121 is embedded with a ring array of nozzles 129 for spraying lubricating oil and gas into the parison.
[0080] The auxiliary mechanism 12 further includes:
[0081] The connecting head 1292 is rotatably arranged at the top of the connecting seat 121 and extends into the sleeve rod 11.
[0082] The liquid guide pipe 124 is sleeved in the sleeve rod 11 and extends to the top of the connecting plate 82. The liquid outlet end of the liquid guide pipe 124 is connected with the liquid inlet end of the connecting head 1292, and the liquid outlet end of the connecting head 1292 is connected with the liquid inlet end of the nozzle 129, so as to convey the lubricating oil into the nozzle 129.
[0083] The auxiliary mechanism 12 further includes:
[0084] The gas guide pipe 127 is sleeved in the sleeve rod 11 and extends to the top of the connecting plate 82. The gas outlet end of the gas guide pipe 127 is fixedly provided with an elbow pipe 1291. The gas outlet end of the elbow pipe 1291 is communicated with the liquid guide pipe 124. The outer wall of the elbow 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 pipe 124 located at the top of the elbow pipe 1291 is provided with a second one-way valve 122 and a second valve body 123. The bottom of the gas guide pipe 127 is rotationally connected with the top of the connecting head 1292.
[0085] The auxiliary mechanism 12 further comprises:
[0086] The fixed rod 126 is fixedly arranged at 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.
[0087] The first limiting rod 1294 is fixedly arranged at the side wall of one end of the fixed rod 126 located at the bottom of the connecting seat 121 and is arranged in an annular array. The first limiting rod 1294 is designed in a bent shape. The top of the first limiting rod 1294 is fixedly provided 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 sleeving the second limiting rod 128. The top of the second limiting rod 128 is designed to protrude outward so as to limit the disengagement of the second limiting rod 128 from the limiting groove.
[0088] In the specific implementation, in the process of forming the parison, the gas pipeline and the lubricating oil pipeline are respectively connected to the gas guide pipe 127 and the liquid guide pipe 124, so that the gas and the lubricating oil are mixed and then sprayed into the parison through the nozzle 129, thereby reducing the adhesion between the inner walls of the parison and increasing the buoyancy of the parison in the air, so as to reduce the uneven distribution of the plastic bottle raw materials of the parison due to the excessive length of the downward sagging after the parison is extruded from between the second guide rod 6 and the guide pipe 5, thereby avoiding the influence on the quality of the pesticide plastic bottle.
[0089] After the gas pipeline and the lubricating oil pipeline are respectively connected to the gas guide pipe 127 and the liquid guide pipe 124, the first valve body 125 and the second valve body 123 are opened. The gas enters the elbow pipe 1291 through the gas guide pipe 127 and enters the liquid guide pipe 124 through the elbow pipe 1291. At the same time, the lubricating oil enters the connecting head 1292 through the liquid guide pipe 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 then sprayed into the parison through the nozzle 129, thereby reducing the adhesion between the inner walls of the parison and reducing the uneven distribution of the plastic bottle raw materials of the parison due to the excessive length of the downward sagging after the parison is extruded from between the second guide rod 6 and the guide pipe 5, thereby avoiding the influence on the quality of the pesticide plastic bottle. By mixing the gas and the lubricating oil and then discharging them into the parison, the uniformity of the distribution of the lubricating oil is improved, thereby improving the effect of reducing the adhesion between the inner walls of the parison.
[0090] When the lubricating oil is sprayed, the parison is discharged through the guide pipe 5 and the second guide rod 6 and continuously moves downward, so that the lubricating oil can be in full contact with the inner wall of the parison, and since the diameter of the side wall of the connecting seat 121 is smaller than the diameter of the outer wall of the second guide rod 6, the spraying of the lubricating oil and the gas does not affect the formation of the parison.
[0091] By arranging the first valve body 125 and the second valve body 123, the gas guide pipe 127 and the liquid guide pipe 124 can be controlled separately. When the parison is uniformly sprayed with the lubricating oil but the gas is insufficient, the second valve body 123 is closed, and the gas is sprayed into the parison through the nozzle 129, so that the parison reaches the specified buoyancy, thereby avoiding the spraying of too much lubricating oil and reducing the uneven distribution of the plastic bottle raw materials caused by the sagging process.
[0092] The connecting head 1292 is a rotary joint, which is a prior art and will not be described here.
[0093] The inner side wall of the second guide rod 6 is fixedly sleeved with a plurality of sealing rings arranged at intervals, so as to dynamically seal between the second guide rod 6 and the sleeve rod 11;
[0094] The length of the sleeve rod 11 located at the top of the connecting pipe 13 is matched with the moving distance of the second limiting rod 128 in the limiting groove, so that the second limiting rod 128 can always limit the second guide rod 6 when the sleeve rod 11 is raised and lowered, and the second guide rod 6 does not rotate.
[0095] The outer wall of the sleeve rod 11 is provided with a sliding mechanism 10 for limiting the sleeve rod 11.
[0096] Please refer to Figure 8 , the sliding mechanism 10 comprises:
[0097] The spline groove 102 is annularly arranged on the inner wall of the first guide rod 32 and the second guide block 33;
[0098] The spline convex strip 101 is annularly arranged on the outer wall of the sleeve rod 11 and is 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.
[0099] Please refer to Figure 8 、 Figure 9 and Figure 11 , the lifting mechanism 8 comprises:
