Detailed Implementation

[0017] To illustrate the technical content, structural features, achieved objectives, and effects of the application in detail, the technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, structure, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0018] This application provides a clamping, adsorption, and transfer device for blow molding barrel production, such as... Figure 1 As shown, a pair of transfer devices 100 are mounted on the blow molding machine in opposite directions to clamp the blow molding barrel 200 between them and carry the clamped blow molding barrel to move in the left-right direction.

[0019] like Figure 2 , 3 As shown, each transfer device 100 includes an adsorption mechanism 10, a transverse movement mechanism 20, and a longitudinal movement mechanism 30. The adsorption mechanism 10 of each transfer device 100 cooperates with the adsorption mechanism 10 of the opposite transfer device 100 to adsorb and clamp the blow-molded barrel 200 between them, ensuring the stability of the blow-molded barrel during the transfer process without damaging the barrel body.

[0020] The adsorption mechanism 10 includes a clamping arm 1 extending in the left-right direction, a pair of adsorption components 2 spaced apart on the clamping arm 1 in the left-right direction, and a mounting plate 3 fixedly installed in the middle of the clamping arm 1. Each adsorption component 2 includes a middle clamping plate 21 and multiple suction cups 22 for adsorbing the blow-molded barrel 200. The middle clamping plate 21 is adjustable in position on the clamping arm 1 in the left-right direction. Multiple suction cups 22 are installed on the middle clamping plate 21, and each suction cup 22 is threaded with an air pipe connector at its tail end, which is connected to an external air source. The external air source applies a suction negative pressure at the suction cup 22, so that the suction cup 22 can adsorb onto the surface of the blow-molded barrel 200.

[0021] like Figure 2 , 4As shown, the middle clamping plate 21 includes a middle mounting portion 211, a left mounting portion 212 mounted on the left end of the middle mounting portion 211, and a right mounting portion 213 mounted on the right end of the middle mounting portion 211. At least one pair of suction cups 22 arranged at intervals along the vertical direction are respectively mounted on the middle mounting portion 211, the left mounting portion 212, and the right mounting portion 213. The middle mounting portion 211 is mounted on the clamping arm 1. The left mounting portion 212 and the right mounting portion 213 are arranged opposite each other and are both inclined from the middle mounting portion 211 to the side away from the clamping arm 1, so that the multiple suction cups 22 on the middle clamping plate 21 can be distributed around the circumference of the blow molding barrel 200, increasing the contact points between the adsorption component 2 and the blow molding barrel 200 and improving the stability of adsorption on the blow molding barrel 200.

[0022] In this embodiment of the application, a pair of adsorption components 2 are respectively installed at the left and right ends of the clamping arm 1.

[0023] The transverse mechanism 20 includes a drive assembly 4 that is connected to the clamping arm 1 and a transverse guide assembly 5 arranged between the clamping arm 1 and the drive assembly 4. The drive assembly 4 is used to drive the adsorption mechanism 10 to move back and forth in the left and right direction. The transverse guide assembly 5 guides the movement of the adsorption mechanism 10 in the left and right direction to avoid the adsorption mechanism 10 from deviating during the movement, which could lead to product damage and personnel safety issues.

[0024] like Figure 2 , 3 As shown, the drive assembly 4 includes a pair of synchronous pulleys 41 facing each other, a synchronous belt 42 passing over the pair of synchronous pulleys 41, a transverse motor 43 connected to one of the synchronous pulleys 41, and a tension block 44 fixed to the synchronous belt 42. The axis of each synchronous pulley 41 extends in the front-back direction, and the synchronous belt 42 extends in the left-right direction and is taut on the pair of synchronous pulleys 41. The transverse motor 43 drives the connected synchronous pulleys 41 to rotate around their own axis. Each synchronous pulley 41 meshes with the synchronous belt 42. When the synchronous pulleys 41 rotate, the synchronous belt 42 moves in the left-right direction, and the tension block 44 fixed to the synchronous belt 42 moves in the left-right direction along with the synchronous belt 42. The tension block 44 includes an upper tension plate 441 and a lower tension plate 442. The upper tension plate 441 and the lower tension plate 442 clamp the upper and lower sides of a section of the synchronous belt 42, which are tightened together by bolts to achieve a fixed connection with the synchronous belt 42.

[0025] The transverse guide assembly 5 includes a fixed frame 51, a linear guide rail 52 mounted on the fixed frame 51, multiple sliders 53 that slide in cooperation with the linear guide rail 52, and a sliding base 54 fixedly connected to the multiple sliders 53. The linear guide rail 52 extends in the left-right direction. A synchronous belt fixing plate 55 is fixedly connected between the sliding base 54 and the tensioning block 44. The lower tensioning plate 442 of the tensioning block 44 is locked to the synchronous belt fixing plate 55 by multiple bolts. The multiple sliders 53 can move back and forth along the linear guide rail 52 to reduce the friction between the sliding base 54 and the fixed frame 51 during movement, ensuring that the sliding base 54 can move smoothly in the left-right direction. When the synchronous belt 42 moves in the left-right direction, the tensioning block 44 drives the synchronous belt fixing plate 55 to move left and right with the synchronous belt 42, so that the sliding base 54 fixed to the synchronous belt fixing plate 55 can move synchronously in the left-right direction, realizing the displacement of the adsorption mechanism 10 in the left-right direction.

[0026] The fixed frame 51 is welded to the frame of the blow molding machine. A pair of synchronous pulleys 41 are supported on the blow molding machine by a pair of wheel frames 45 welded to the frame of the blow molding machine, so that a pair of transfer devices 100 can be supported as a whole on the blow molding machine.

[0027] The transverse motors 43 of the pair of transfer devices 100 cooperate with each other. When the pair of transfer devices 100 transfer the blow molding barrel 200, the pair of transverse motors 43 are driven synchronously, so that the adsorption mechanism 10 of the pair of transfer devices 100 can move synchronously in the left and right directions, thereby ensuring the stability of the blow molding barrel 200 during the transfer process.

[0028] like Figure 2-5 As shown, the longitudinal movement mechanism 30 includes a stroke-adjustable cylinder 6 and multiple longitudinal movement guide components 7, which are connected in a transmission manner between the drive assembly 4 and the mounting plate 3. The stroke-adjustable cylinder 6 can drive the adsorption mechanism 10 to move in the front-back direction relative to the transverse movement mechanism 20, and can also move in the left-right direction along with the connected adsorption mechanism 10 under the drive of the drive assembly 4. The stroke-adjustable cylinder 6 includes a cylinder body and a pneumatic rod that is movably mounted in the cylinder body in the front-back direction. The cylinder body is fixedly connected to the timing belt fixing plate 55, and the pneumatic rod is fixedly connected to the mounting plate 3 on the clamping arm 1. A through hole is provided on the sliding base 54 for the pneumatic rod to pass through in the front-back direction. When the stroke-adjustable cylinder 6 is working, the pneumatic rod extends and retracts, allowing the mounting plate 3 to move in the front-back direction relative to the sliding base 54, thus completing the displacement of the adsorption mechanism 10 in the front-back direction. Since the timing belt fixing plate 55 fixes the tension block 44, the cylinder body of the stroke adjustable cylinder 6 and the sliding base 54 together, when the timing belt 42 drives the tension block 44 to move left and right, the stroke adjustable cylinder 6, the sliding base 54 and the adsorption mechanism 10 connected to the air rod of the stroke adjustable cylinder 6 can move synchronously in the left and right direction. The cooperation between the slider 53 at the bottom of the sliding base 54 and the linear guide rail 52 restricts the lateral displacement of the adsorption mechanism 10.

[0029] Multiple longitudinal guide components 7 restrict the direction of displacement of the adsorption mechanism 10 relative to the sliding base 54 when the stroke-adjustable cylinder 6 drives it to move in the front-back direction. Each longitudinal guide component 7 includes a guide rod 71 mounted on the mounting plate 3 and a guide sleeve 72 mounted on the sliding base 54. The guide rod 71 extends in the front-back direction and is configured to move in the front-back direction through the corresponding guide sleeve 72. The guide sleeves 72 of each longitudinal guide component 7 are arranged to avoid through holes. The guide sleeves 72 are made of brass and graphite. Graphite has lubricating properties, which improves the movement effect of the guide rod 71 and enhances the guiding performance of the guide rod 71. Each longitudinal guide component 7 ensures the straightness of the mounting plate 3 during movement.

[0030] Multiple longitudinal guide components 7 are arranged in pairs along the vertical direction on the sliding base 54. Each pair of longitudinal guide components 7 is arranged opposite each other on the left and right sides of the through hole, and multiple pairs of longitudinal guide components 7 are arranged opposite each other on the upper and lower sides of the through hole. The multiple longitudinal guide components 7 are evenly and symmetrically arranged on the outside of the stroke adjustable cylinder 6, so that when the stroke adjustable cylinder 6 drives the adsorption mechanism 10 to move back and forth, the mounting plate 3 is always parallel to the sliding base 54 during the movement.

[0031] The working principle of this application is as follows: the transverse motors 43 of a pair of transfer devices 100 synchronously drive the adsorption mechanism 10 to move laterally to a suitable clamping position. Each adsorption component 2 is aligned with the corresponding blow molding barrel 200. The stroke adjustable cylinders 6 of the pair of transfer devices 100 work simultaneously to push the adsorption mechanism 10 toward the corresponding blow molding barrel 200. After the adsorption mechanism 10 of the pair of transfer devices 100 clamps the corresponding blow molding barrel 200, the external air source works, and each suction cup 22 applies suction negative pressure to adsorb onto the surface of the blow molding barrel 200, thereby stably clamping the blow molding barrel 200. The pair of adsorption mechanisms 10 move laterally synchronously under the drive of the transverse motors 43 to transfer the clamped blow molding barrel 200 to another station. After the work is completed, the external air source is withdrawn, each suction cup 22 is depressurized, and the pair of stroke adjustable cylinders 6 retract, thereby putting down the clamped blow molding barrel 200, thus completing the transfer work of the blow molding barrel.

[0032] This application uses an adjustable-stroke cylinder to clamp the blow-molded barrel, with an adjustable clamping distance. The suction cup uses the principle of vacuum negative pressure adsorption, which ensures the adsorption effect and improves the stability of the clamping process without damaging the barrel body. At the same time, the relative connection of the adjustable-stroke cylinder, the adsorption mechanism and the drive component allows the adjustable-stroke cylinder and the adsorption mechanism to move synchronously in the left and right directions under the drive of the drive component, ensuring the accuracy of the movement position and improving the transfer efficiency and safety.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made without departing from the spirit and scope of this application. The scope of protection claimed by this application is defined by the appended claims, specification, and their equivalents.
