Description

Technical Field

[0001] This utility model relates to the field of plastic container processing technology, specifically a multi-angle blow molding device for plastic container processing. Background Technology

[0002] Blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method. With the advent of high-density polyethylene and the development of blow molding machines, blow molding technology has been widely applied. Hollow containers can reach volumes of several thousand liters, and some production processes have adopted computer control. Plastics suitable for blow molding include polyethylene, polyvinyl chloride, polypropylene, and polyester, and the resulting hollow containers are widely used as industrial packaging containers.

[0003] In the prior art, such as the multi-angle blow molding device for processing plastic containers disclosed in CN221622989U, the device connects the fixed seat and the mounting seat under the action of the column. Then, the mounting plate is placed on the top of the mounting seat and positioned by the positioning bolts, which makes it convenient for the user to disassemble and assemble the mounting plate. The mounting plate is connected to the turntable under the action of the working motor, which makes it convenient to adjust the rotation direction of the working plate.

[0004] In the field of plastic container processing, existing technologies use components such as fixed seats to adjust the working plate, thereby adjusting the direction of the blow molding head. However, in actual use, when the blow molding head is inserted into the mold, the blow molding channel is a single hole, which cannot perform blow molding at multiple angles, resulting in slow overall blow molding efficiency. At the same time, some parts may be unstable under pressure, leading to uneven wall thickness. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that the existing blow molding channels are all single-hole when the material is inserted into the mold for blow molding, multi-angle blow molding is not possible, resulting in slow overall blow molding efficiency and the possibility of unstable pressure in some areas, leading to uneven wall thickness.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A multi-angle blow molding apparatus for processing plastic containers, characterized in that it comprises:

[0009] The support shell has a sealing door movably connected to its front end, and a blow molding equipment body is fixedly installed on one side of the top of the support shell. A lower pressure plate is slidably connected to one side of the blow molding equipment body, and an adjustment mechanism is provided above the lower pressure plate.

[0010] The adjustment mechanism includes a telescopic tube, which is fixedly installed inside the lower pressure plate. A fixed tube is sleeved on the top end of the telescopic tube, and a rotating tube is rotatably connected to the bottom end of the telescopic tube. A blow molding groove is opened on the lower outer wall of the rotating tube.

[0011] As a further improvement of this utility model: a gear is fixedly installed on the upper part of the outer wall of the rotating tube, a servo motor is fixedly installed on one side of the telescopic tube at the top of the lower pressure plate, and a drive rod is fixedly installed on the power output end of the servo motor.

[0012] As a further improvement of this utility model: a connector is fixedly installed at the bottom end of the rotating tube, and a blow molding hole is opened at the bottom end of the connector.

[0013] As a further embodiment of this utility model: the fixed tube and the telescopic tube form a sliding structure, and the telescopic tube and the rotating tube form a rotating structure.

[0014] As a further improvement of this utility model: a rubber plate is embedded on one side of the blow molding equipment body at the top of the bearing shell, and a stabilizing mechanism is provided above the rubber plate.

[0015] As a further embodiment of this utility model: the stabilizing mechanism includes a mounting rod, which is fixedly installed below the gear on the outer wall of the rotating tube, and a movable rod is fixedly installed at the bottom end of the mounting rod, with a sleeve sleeved at the bottom end of the movable rod.

[0016] As a further improvement of this utility model: a sealing gasket is fixedly installed at one end of the moving rod that passes through the sleeve, and a vent hole is provided on the outer wall of the sleeve.

[0017] As a further improvement of this utility model: an elastic telescopic rod is fixedly installed at the top of the rubber sheet, and a support ring is fixedly installed at the top of the elastic telescopic rod.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model, through the design of a rotating tube, blow molding groove, gear, servo motor and blow molding hole, enables multi-angle blow molding of plastic containers in the mold, avoiding uneven pressure and affecting the uniformity of wall thickness. At the same time, multi-angle blow molding can improve the overall blow molding efficiency, and with the rotation of the rotating tube, it can avoid dead corners, which would cause pressure loss in some areas and affect the blow molding effect.

[0020] 2. This utility model, through the design of the moving rod, sleeve, sealing gasket, elastic telescopic rod and support ring, can reserve space for the travel of the rotating tube and maintain stability during the travel process. At the same time, it can maintain stability during the rotation of the rotating tube, avoiding the shaking of the rotating tube from affecting the blow molding effect, thereby affecting the quality and aesthetics of the plastic container.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0030] Example 1

[0031] Please see Figures 1 to 3 This is the first embodiment of the present utility model. This embodiment provides a multi-angle blow molding device for processing plastic containers, including: a support shell 1, a sealing door 2 movably connected to the front end of the support shell 1, a blow molding equipment body 3 fixedly installed on one side of the top of the support shell 1, a lower pressure plate 4 slidably connected to one side of the blow molding equipment body 3, and an adjustment mechanism 5 provided above the lower pressure plate 4.

[0032] The adjustment mechanism 5 includes a telescopic tube 501, which is fixedly installed inside the lower pressure plate 4. A fixed tube 502 is sleeved on the top end of the telescopic tube 501, and a rotating tube 503 is rotatably connected to the bottom end of the telescopic tube 501. A blow molding groove 504 is provided on the lower outer wall of the rotating tube 503.

[0033] Specifically, a gear 505 is fixedly installed on the upper part of the outer wall of the rotating tube 503, a servo motor 506 is fixedly installed on one side of the telescopic tube 501 at the top of the lower pressure plate 4, and a drive rod 507 is fixedly installed on the power output end of the servo motor 506.

[0034] Furthermore, through the cooperation of the servo motor 506 and the drive rod 507, and the meshing of the two gears 505, the rotating tube 503 can rotate under the rotational engagement of the telescopic tube 501, thereby causing the blow molding tank 504 to rotate, forming multi-angle blow molding to improve the uniformity of internal pressure and make the container wall thickness uniform.

[0035] Specifically, a connector 508 is fixedly installed at the bottom end of the rotating tube 503, and a blow molding hole 509 is opened at the bottom end of the connector 508.

[0036] Furthermore, the blow molding hole 509 at the bottom of the connector 508 allows for multi-angle blow molding downwards or to the lower side, further improving the efficiency and uniformity of the entire blow molding process.

[0037] Specifically, the fixed tube 502 and the telescopic tube 501 form a sliding structure, and the telescopic tube 501 and the rotating tube 503 form a rotating structure.

[0038] Furthermore, by slidingly engaging the fixed tube 502 with the telescopic tube 501, and by rotating and engaging the telescopic tube 501 with the rotating tube 503, the rotating tube 503 can be inserted into the mold inside the bearing shell 1 and can be rotated for blow molding.

[0039] In use, the main body 3 of the blow molding equipment consists of multiple parts, including a control system, a power system, a material conveying system, and a blow molding system. This is conventional technology and will not be described in detail here. The opening and closing of the sealing door 2 facilitates the placement of the mold inside the bearing shell 1. At the same time, the power system causes the lower pressure plate 4 to move, allowing the rotating tube 503 to be inserted into the pre-drilled hole in the bearing shell 1 and enter the mold for blow molding. The fixed tube 502 is connected to the blow molding system, etc., which allows the rotating tube 503 to be inserted into the mold and blow molded through the blow molding groove 504 after sliding displacement via the telescopic tube 501. With the help of the connector 508 and the blow molding hole 509, multi-angle blow molding is possible. With the help of the servo motor 506, the drive rod 507 is rotated. Through the transmission of two gears 505, the rotating tube 503 rotates, which can maintain the uniformity of the blow molding pressure and avoid dead angles.

[0040] In summary, by setting multiple blow molding grooves 504 and blow molding holes 509, multi-angle blow molding can be achieved, improving the uniformity of blow molding and increasing the overall blow molding efficiency. At the same time, with the servo motor 506 and drive rod 507 providing power, the rotating tube 503 can be rotated through the transmission of two gears 505 to avoid dead angles during blow molding, which would cause uneven thickness of the blow-molded container.

[0041] Example 2

[0042] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 This is the second embodiment of the present invention, which provides an improved design for a multi-angle blow molding device for processing plastic containers.

[0043] Specifically, a rubber plate 6 is embedded on one side of the blow molding equipment body 3 at the top of the bearing shell 1, and a stabilizing mechanism 7 is set above the rubber plate 6.

[0044] Furthermore, a rubber plate 6 is bonded to one side of the bearing shell 1 corresponding to the reserved hole of the rotating tube 503. The rubber plate 6 has a reserved hole, which is slightly smaller than the rotating tube 503. The elasticity of the rubber allows the rotating tube 503 to be inserted, thus achieving a certain degree of sealing.

[0045] Specifically, the stabilizing mechanism 7 includes a mounting rod 701, which is fixedly installed below the gear 505 on the outer wall of the rotating tube 503. A movable rod 702 is fixedly installed at the bottom end of the mounting rod 701, and a sleeve 703 is sleeved at the bottom end of the movable rod 702.

[0046] Furthermore, by having two movable rods 702 slide along the sleeve 703 and be fixed to the outer wall of the rotating tube 503 by the mounting rod 701, the stability of the rotating tube 503 when inserted into the bearing shell 1 can be improved.

[0047] Specifically, a sealing gasket 704 is fixedly installed at one end of the moving rod 702 that passes through the sleeve 703, and a vent hole 705 is provided on the outer wall of the sleeve 703.

[0048] Furthermore, the sealing gasket 704 and the vent 705 allow the moving rod 702 and the sleeve 703 to slide and extend in a piston-like manner, thereby further improving the stability of the displacement process.

[0049] Specifically, an elastic telescopic rod 706 is fixedly installed at the top of the rubber sheet 6, and a support ring 707 is fixedly installed at the top of the elastic telescopic rod 706.

[0050] Furthermore, the slots opened in the support ring 707 correspond to the casters at the bottom of the moving rod 702, which can improve the stability of the rotating tube 503 during rotation.

[0051] In use, when the rotating tube 503 is displaced, the two moving rods 702 slide along the sleeve 703 driven by the mounting rod 701, and together with the sealing gasket 704 and the vent hole 705, they form a piston motion to improve stability. At the same time, the universal wheel at the bottom of the moving rod 702 rotates and engages with the groove of the support ring 707, which can keep the rotating tube 503 rotating stably. The support ring 707, through the elastic telescopic rod 706, reserves space and maintains stability when the rotating tube 503 is displaced.

[0052] In summary, the telescopic structure formed by the moving rod 702 and the sleeve 703 creates a piston motion, while the elastic telescopic rod 706 provides space for the rotating tube 503 to insert into the bearing shell 1 and the mold, and maintains stability during the displacement process. Furthermore, the slot of the support ring 707 and the universal wheel at the bottom of the moving rod 702 enhance the stability of the rotating tube 503 during rotation.
