Description

Technical Field

[0002] Existing hollow plastic products are usually made by extrusion blow molding machines, and when in use, the extrusion blow molding machine mainly extrude a softened thermoplastic parison through an extrusion die head, and then put the thermoplastic parison into the middle of an open mold, and then the mold is closed. After the mold is closed, the cutting device cuts off the upper end of the thermoplastic parison, so that the thermoplastic parison in the mold and the extrusion die head are disconnected, and then the mold is moved to the position of the upper blowing needle, and the thermoplastic parison in the mold is blown and extruded by the upper blowing needle. The blow-molded product after molding is manually taken out.

[0003] However, the existing blow molding machines also use a downward blowing object to blow and extrude the thermoplastic parison in the mold, so that the opening end of the blow-molded product after molding faces downward. When the blow-molded product after molding needs to be leak-tested, it is necessary to separately set up a flipping device to flip the blow-molded product with the opening facing downward so that its opening faces upward. In addition, in order to avoid the operation of manual material removal, a clamping device is currently used to automatically clamp the molded blow-molded product. However, separately setting up a clamping device and a flipping device will cause the extrusion blow molding machine to occupy a larger area and have low working efficiency.

There is no need to use a separate clamping device and flipping device, which reduces the processing cost and reduces the equipment footprint.

[0037] like Figure 1As shown, a clamping unit 50 is commonly connected at two opposite ends of the moving frame 103, and the clamping unit 50 includes: a guide rod 501, two guide rods 501 are symmetrically arranged and respectively connected to the two ends of the moving frame 103, a first locking block 107 is fixedly sleeved on the outer periphery of the two guide rods 501, and the two first locking blocks 107 are fixedly arranged on the lower surface of the moving frame 103 through a pin shaft, and a bottom plate 502 is commonly connected at one end of the two guide rods 501, and two symmetrical side plates 503 are arranged on the surface of the bottom plate 502 and are divided into a first side plate and a second side plate, a first clamping mechanism 40 is movably arranged on the inner surface of the first side plate, and a second clamping mechanism 60 is movably arranged on the inner surface of the second side plate, and the first clamping mechanism 40 and the second clamping mechanism 60 can be used to approach each other to clamp the blow-molded product, and the clamping direction of the first clamping mechanism 40 and the second clamping mechanism 60 is toward the waste clamping mechanism 30.

[0038] like Figure 1 , 2 As shown in Figure 4, the first clamping mechanism 40 includes: a first pushing cylinder 401, the first pushing cylinder 401 is fixedly arranged on the surface of the first side plate, the working end of the first pushing cylinder 401 extends out of the surface of the first side plate, the first supporting arm 402 is fixedly connected to the working end of the first pushing cylinder 401, the surface of the first supporting arm 402 is provided with a first guide rod movably connected to the first side plate, an active clamping disk 403 is rotatably connected to the side surface of one end of the first supporting arm 402 through a bearing, a driven gear 407 is arranged at one end of the active clamping disk 403, a fixed frame 404 is fixedly sleeved on the outer periphery of one end of the first supporting arm 402 close to the first side plate, a rotating motor 405 is fixedly arranged on the surface of the fixed frame 404, a driving gear is fixedly arranged on the working end of the rotating motor 405, and the driving gear is transmission-connected to the driven gear 407 through a toothed belt 406.

[0039] like Figure 1 , 2 As shown in Figure 4, the second clamping mechanism 60 includes: a second push cylinder 601, the second push cylinder 601 is fixedly arranged on the surface of the second side plate, the working end of the second push cylinder 601 extends out of the surface of the second side plate, the working end of the second push cylinder 601 is fixedly connected with a second support arm 602, the surface of the second support arm 602 is provided with a second guide rod movably connected with the second side plate, and the side surface of one end of the second support arm 602 is rotatably connected with a driven clamping disk 603 through a bearing, and the driven clamping disk 603 is symmetrically arranged with the active clamping disk 403. Through the cooperation between the first clamping mechanism 40 and the second clamping mechanism 60, the blow-molded product with the opening facing downward can be turned over so that the opening facing downward faces upward, which is convenient for the subsequent leak detection station to directly perform leak detection on the blow-molded product, and there is no need to manually adjust the opening direction of the blow-molded product, thereby improving the processing efficiency.

[0040] The working principle of the utility model is as follows: the manipulator of the utility model is installed on the mounting frame of the extrusion blow molding machine so that the manipulator is located between the blow molding product forming station and the side leakage station. Since the extrusion blow molding machine is a prior art, the method of using the extrusion blow molding machine will not be described in detail here, and only a brief description will be given to facilitate understanding of the working principle of the utility model. When the extrusion blow molding machine processes the blow molded product, the extrusion die head extrude the softened thermoplastic parison, and then the mold in the open mold state wraps the softened thermoplastic parison in the mold, the mold in the open mold state is closed, and then the softened thermoplastic parison on the extrusion die head is sheared by the shearing device, and the mold in the closed mold state is moved to the molding station for blowing processing through the lower blowing needle, and the blow molded product after molding needs to be removed because there will be parison waste at the upper end of the mold during shearing.

[0041] Therefore, when the mold moves to the molding station, the sheared waste at the upper end of the mold is in the middle of the open clamping plate 308. During the film blowing process, the lifting cylinder 303 is started to drive the connecting head 305 to move upward. During the upward movement of the connecting head 305, the connecting rod 306 is driven to move. The rotating plate 307 is rotated around the axis of the rotating shaft 309 through the connecting rod 306, so that the two clamping plates 308 are close to each other, and the waste at the upper end of the mold is clamped by the clamping plate 308. Then, when the blow molding of the parison in the mold is completed, the mold is opened, and the reduction motor 20 is started to drive the moving frame 103 to move toward the waste clamping mechanism 30 along the extension direction of the slide rail 105. 03 drives the clamping unit 50, the first clamping mechanism 40, and the second clamping mechanism 60 to follow and move. When the mobile frame 103 moves a certain distance, the reduction motor 20 stops, and the first push cylinder 401 and the second push cylinder 601 are started, so that the first support arm 402 and the second support arm 602 are close to each other to clamp the blow-molded product. When the active clamping plate 403 and the driven clamping plate 603 are both attached to the surface of the blow-molded product, the first push cylinder 401 and the second push cylinder 601 stop, and the reduction motor 20 restarts to drive the mobile frame 103 to reset, thereby driving the first clamping mechanism 40, the second clamping mechanism 60, and the blow-molded product to move through the mobile frame 103;

[0042] During the movement of the blow-molded product, the rotating motor 405 starts to drive the driven gear 407 to rotate through the toothed belt 406, thereby driving the active clamping disk 403 to rotate through the driven gear 407, and driving the blow-molded product to rotate through the active clamping disk 403 and the driven clamping disk 603, so that the blow-molded product's opening originally facing downward becomes facing upward, and then the rotating motor 405 stops, and the first push cylinder 401 and the second push cylinder 601 reset to release the clamping of the blow-molded product, so that the blow-molded product falls onto the conveyor belt (not shown in the figure), and the blow-molded product is moved to the leak detection station through the conveyor belt for subsequent inspection and processing.

[0043] Although the above describes the illustrative specific implementation methods of the present application so that technicians in this technical field can understand the present application, the present application is not limited to the scope of the specific implementation methods. For ordinary technicians in this technical field, as long as various changes are within the spirit and scope of the present application defined and determined by the attached claims, all application creations using the concept of the present application are protected.
