Description

Technical Field

[0001] This utility model relates to the field of blow molding clamp technology, specifically a bottle clamp with a flipping function. Background Technology

[0002] Traditional PET bottle blowing machines are components used to grip preforms and feed them into the mold, and to grip bottles from the mold and output them outwards. They rely on the preforms or bottles to push open the spring-loaded gripper openings to complete the gripping and releasing of the preforms or bottles.

[0003] The existing publication number CN119217690B discloses a gripper assembly for a rotary blow molding machine, including a support arm, a gripping mechanism, an expansion mechanism, a front observation mechanism, a fine-tuning component, and an auxiliary locking mechanism. The support arm has symmetrically opened through holes through which a rotating central shaft of the gripping mechanism is rotatably connected via bearings. The bottom end of the rotating central shaft is fixed to a flipping block. This invention adds an expansion mechanism that can drive the flipping block to the traditional gripper structure, eliminating the need for the bottle mouth to push open the gripper, preventing impact deformation at the bottle mouth gripping position, reducing product loss, and avoiding PET debris from contaminating the product during gripping and releasing.

[0004] Existing blow molding clamps can only perform the function of clamping, but cannot flip the blown products. Therefore, we propose a bottle clamp with a flipping function. Utility Model Content

[0005] The purpose of this invention is to provide a bottle clip with a flipping function to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bottle clamp with a flipping function, comprising an outer seat, an inner seat, an inner groove cam, and a clamping assembly, wherein the outer seat and the inner seat rotate synchronously relative to the inner groove cam; the clamping assembly comprises a nut seat, a screw, a guide rod, and a clamping assembly, wherein the nut seat is equipped with the screw and the guide rod, and both ends of the screw are rotatably connected to the outer seat and the inner seat respectively through bearings, and a clamping assembly is installed at one end of the screw; when the outer seat and the inner seat drive the clamping assembly to rotate, the inner groove cam can drive the nut seat to reciprocate, and the reciprocating movement of the nut seat drives the screw to rotate.

[0007] Preferably, the bottom of the nut seat is provided with a guide wheel that cooperates with the guide groove of the inner groove cam.

[0008] Preferably, a plurality of clamping components are provided, and the plurality of clamping components are distributed at equal intervals on the outer side of the inner seat.

[0009] Preferably, the clamping assembly includes a base, a roller, a first clamping jaw, and a second clamping jaw. The base is rotatably mounted with the first clamping jaw and the second clamping jaw via a pin. The first clamping jaw and the second clamping jaw engage with each other via teeth. One end of the first clamping jaw is rotatably mounted with a roller via a pin.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the outer seat and the inner seat are as a whole, and the relatively fixed inner groove cam rotates synchronously, driving multiple clamping components installed on the outer side of the inner seat to rotate together. In the clamping components, the guide wheel at the bottom of the nut seat precisely matches the guide groove of the inner groove cam. When the clamping components rotate with the outer seat and the inner seat, the guide wheel slides along the guide groove trajectory. Constrained by the shape of the guide groove, the nut seat is forced to achieve reciprocating linear movement (towards / away from the inner groove cam). The nut seat and the screw are threadedly connected, and the two ends of the screw are rotatably connected to the outer seat and the inner seat through bearings. When the nut seat moves back and forth, the threaded drive drives the screw to rotate around its own axis; the clamping component connected to one end of the screw rotates synchronously with the screw, ultimately realizing the flipping action of the bottle; multiple clamping components are evenly distributed on the outer side of the inner seat, which can simultaneously perform clamping and flipping operations on multiple groups of bottles; and each component is synchronously driven by the outer seat and the inner seat, with high consistency of action, adapting to the mass production scenario of rotary blow molding machines and improving production efficiency.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0020] Please see Figure 1-6 In this embodiment of the present invention, a bottle clamp with a flipping function includes an outer seat 1, an inner seat 2, an inner groove cam 3, and a clamping assembly 4. The outer seat 1 and the inner seat 2 rotate synchronously relative to the inner groove cam 3. Multiple clamping assemblies 4 are provided, and are evenly distributed on the outer side of the inner seat 2. Each clamping assembly 4 includes a nut seat 41, a screw 42, a guide rod 43, and a clamping assembly 44. The nut seat 41 is equipped with the screw 42 and the guide rod 43. Both ends of the screw 42 are rotatably connected to the outer seat 1 and the inner seat 2 respectively via bearings. The clamping assembly 44 is installed at one end of the screw 42. When the outer seat 1 and the inner seat 2 drive the clamping assembly 4 to rotate, the inner groove cam 3 can drive the nut seat 41 to reciprocate. The reciprocating movement of the nut seat 41 drives the screw 42 to rotate. The bottom of the nut seat 41 is provided with a guide wheel that mates with the guide groove of the inner groove cam 3. The guide wheel at the bottom of the nut seat precisely mates with the guide groove of the inner groove cam. As the clamping assembly rotates with the outer and inner seats, the guide wheel slides along the guide groove trajectory. Constrained by the shape of the guide groove, the nut seat is forced to reciprocate linearly (moving closer to / away from the inner groove cam). The nut seat and the screw are threadedly connected, and both ends of the screw are rotatably connected to the outer and inner seats through bearings. When the nut seat reciprocates, the threaded drive drives the screw to rotate around its own axis; the clamping assembly connected to one end of the screw rotates synchronously with the screw, ultimately achieving the flipping action of the bottle.

[0021] The clamping assembly 4 includes a base 441, a roller 442, a first gripper 443, and a second gripper 444. The base 441 is rotatably mounted with the first gripper 443 and the second gripper 444 via a pin. The first gripper 443 and the second gripper 444 are engaged by teeth. One end of the first gripper 443 is rotatably mounted with the roller 442 via a pin. In the clamping assembly, the first gripper and the second gripper are linked by tooth engagement to achieve stable clamping of the bottle (the opening and closing of the first gripper and the second gripper are realized by an external drive assembly).

[0022] The working principle of this utility model is as follows: the outer seat and the inner seat are as a whole, and the relatively fixed inner groove cam rotates synchronously, driving multiple clamping components installed on the outer side of the inner seat to rotate together with it.

[0023] In the clamping assembly, the guide wheel at the bottom of the nut seat precisely engages with the guide groove of the inner groove cam. As the clamping assembly rotates with the outer and inner seats, the guide wheel slides along the guide groove trajectory. Constrained by the shape of the guide groove, the nut seat is forced to reciprocate linearly (towards / away from the inner groove cam).

[0024] The nut seat and the screw are connected by a thread, and both ends of the screw are rotatably connected to the outer and inner seats through bearings. When the nut seat moves back and forth, the thread drive drives the screw to rotate around its own axis; the clamp assembly connected to one end of the screw rotates synchronously with the screw, ultimately realizing the flipping action of the bottle.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
