Description

Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to a side suction jig for bottle embryos. Background Art

[0002] The preform is the prototype of the PET bottle before it is formed. The preform can be prepared by a one-piece mold. However, the existing mold can simultaneously mold dozens of products. The products are relatively scattered, with a small distance between each two products and a large span between products. In addition, the surface of these products is smooth and curved, and no marks should be left on the product surface. Considering the weight of the jig and the space required for product removal, as well as the need to maintain a certain verticality when removing the bottle preform, traditional jigs cannot automatically remove multiple products. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the utility model provides a bottle embryo side suction fixture, which solves the problem that the traditional fixture cannot automatically take out multiple products.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a side suction jig for bottle preforms, comprising a jig plate, the surface of which is symmetrically provided with a side suction linkage device, the surface of which is provided with a positioning sleeve, and the inner cavity of the positioning sleeve is provided with a bottle preform.

[0005] The side suction linkage device includes upper and lower hardware fixing plates and a cylinder, and the surface of the hardware fixing plate is fixedly sleeved with a guide post through a guide post fixing plate, the surface of the guide post is symmetrically and slidingly sleeved with a linear bearing, and the surface of the linear bearing is fixedly sleeved with a bearing fixing seat, the surface of the hardware fixing plate is fixedly sleeved with a hardware head, and one end of the hardware head is fixedly connected to a suction cup, and the output end of the cylinder is fixedly connected to the surface of any upper or lower hardware fixing plate.

[0006] Preferably, the bearing fixing seat and the cylinder are both fixedly connected to the surface of the jig plate.

[0007] Preferably, the positioning sleeve is fixedly sleeved on the surface of the jig plate.

[0008] Preferably, a through hole for the suction cup to adsorb is opened on the surface of the positioning sleeve.

[0009] Preferably, both ends of the guide column pass through the surface of the hardware fixing plate and extend to the outside.

[0010] The utility model provides a side suction fixture for preforms. Compared with the existing technology, it has the following advantages:

[0011] This preform side suction fixture uses a cylinder to drive the hardware fixing plate to slide through the guide column, so that multiple suction cups can suck the preform tightly in a vacuum form, thereby clamping multiple preforms at one time, solving the problem that many products with large spans cannot be automatically removed using conventional fixtures. The vertical end of the preform can also be ensured through the adsorption of the positioning sleeve and the suction cup. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-5 The utility model provides a technical solution: a bottle preform side suction fixture, including a fixture plate 4, a side suction linkage device 3 is symmetrically arranged on the surface of the fixture plate 4, and a positioning sleeve 2 is arranged on the surface of the side suction linkage device 3, and the inner cavity of the positioning sleeve 2 is provided with a bottle preform 1, the positioning sleeve 2 is fixedly sleeved on the surface of the fixture plate 4, and the surface of the positioning sleeve 2 is provided with a through hole for the suction cup 31 to adsorb. Please refer to Figure 4 In this way, the suction cup 31 enters the through hole and fits on the bottle blank 1. The suction cup 31 is vacuumed to suck the bottle blank 1 tightly.

[0025] The air inlet end of the hardware head 32 is connected to the hose, and the hose is bound in a suitable position, and then the hose is connected to an external vacuum pump. In this way, during operation, the suction cup 31 is sucked by the external vacuum pump and the hose to create a vacuum, thereby sucking the bottle blank 1 tightly.

[0026] See also Figure 6-10 The side suction linkage device 3 includes an upper and lower hardware fixing plate 33 and a cylinder 38, and the surface of the hardware fixing plate 33 is fixedly sleeved with a guide post 37 through a guide post fixing plate 34. Both ends of the guide post 37 pass through the surface of the hardware fixing plate 33 and extend to the outside. The surface of the guide post 37 is symmetrically and slidingly sleeved with a linear bearing 36, and the surface of the linear bearing 36 is fixedly sleeved with a bearing fixing seat 35. The surface of the hardware fixing plate 33 is fixedly sleeved with a hardware head 32, and one end of the hardware head 32 is fixedly connected to the suction cup 31. The output end of the cylinder 38 is fixedly connected to the surface of one of the upper and lower hardware fixing plates 33. It is only necessary to drive one of the hardware fixing plates 33 to move through the cylinder 38. The bearing fixing seat 35 and the cylinder 38 are both fixedly connected to the surface of the fixture plate 4.

[0027] During operation, the bottle blank 1 is first placed into the positioning sleeve 2 by the robot arm, and then the cylinder 38 is started, so that the output end of the cylinder 38 pushes one of the upper and lower hardware fixing plates 33, wherein the hardware fixing plate 33 is fixedly connected to the guide post 37 through the guide post fixing plate 34, so that the guide post 37 slides in the inner cavity of the linear bearing 36, thereby causing the upper and lower hardware fixing plates 33 to move simultaneously, so that the suction cup 31 passes through the through hole opened on the surface of the positioning sleeve 2 and contacts the surface of the bottle blank 1, and then the vacuum pump is started and the suction cup 31 is sucked through the hose, so that the suction cup 31 forms a vacuum to suck the bottle blank 1 tightly, thereby ensuring the verticality of the bottle blank 1. When taking out, the vacuum pump is turned off, so that the suction cup 31 loses the suction force on the bottle blank 1, and finally the bottle blank 1 is taken out of the mold by the action of the robot arm. Therefore, the design of the cylinder 38 linking multiple suction cups 31 successfully solves the problem that multiple products with a large span cannot be automatically taken out using conventional jigs.
