Description

Technical Field

[0001] The utility model belongs to the technical field of medical infusion bottle processing, and specifically relates to an empty bottle steering auxiliary mechanism in a blowing and filling connecting line clamping device for an infusion bottle. Background Art

[0002] In the medical field, infusion bottles are often used for infusion. In the production and processing of empty infusion bottles, they need to be blown into shape using a preheated biaxial stretch blow molding machine. After molding, they need to be transported to the subsequent process for bottle washing through the blowing and filling line clamping mechanism. The bottle washing equipment in the subsequent process needs to flip the empty bottles 180° before handing them over to the bottle washing machine. This requires that the empty bottles be turned 90° when they are clamped and transported on the blowing and filling line mechanism, otherwise the subsequent 180° flipping action cannot be met. The existing practice is to set a silicone baffle on one side of the bottle body. When the empty bottle moves to the silicone baffle, because the empty bottle is clamped by the clamping mechanism, it can only rotate slightly due to friction with the silicone baffle and cannot rotate 90°.

[0003] In view of this, this patent application is filed. Utility Model Content

[0018] The advantages and beneficial effects of the utility model compared to the prior art are:

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the scope of protection of the present invention.

[0031] The existing blowing and filling line clamping device includes a machine base 5, a finger empty bottle clamping mechanism 3 and a conveyor belt. A plurality of finger empty bottle clamping mechanisms 3 are provided and arranged on the conveyor belt. The conveyor belt is arranged on the machine base 5. The conveyor belt moves forward with each finger empty bottle clamping mechanism 3 during transportation. Among them, the finger 302 empty bottle holding mechanism is in the shape of a finger 302 clamping, including two finger arms 301, two fingers 302 at the ends of the finger arms 301, and a reset spring is connected between the two finger arms 301. The two finger arms 301 can rotate, so that the finger 302-shaped clamping claws open and close to clamp and release the empty infusion bottle.

[0032] like Figure 1As shown in the figure, an empty bottle steering auxiliary mechanism in a blowing and filling line clamping device for an infusion bottle comprises an opening and closing abutment member 1 and a friction steering contact member 2, wherein the opening and closing abutment member 1 and the friction steering contact member 2 are fixed on a base 5 of the blowing and filling line clamping device and are located on both sides of a finger empty bottle clamping mechanism 3. The opening and closing abutment member 1 is located on a side close to a finger arm 301 of the finger empty bottle clamping mechanism 3, and the friction steering contact member 2 is located on a side close to a finger 302 of the finger empty bottle clamping mechanism 3, and the two are arranged on both sides of the finger empty bottle clamping mechanism 3.

[0033] The opening and closing abutment member 1 has a straight section 101 and an arc section 102. The distance between the straight section 101 and the end of the finger arm 301 is smaller than the distance between the arc section 102 and the end of the finger arm 301. The distance between the straight section 101 and the end face of the finger arm 301 is 0, so that the finger arm 301 contacts the straight section 101 during the movement to produce a friction abutment effect, which can make a finger arm 301 rotate and make the "claw" slightly open. The slight opening makes a gap between the bottleneck of the empty bottle and the finger 302 and loosens, so that the empty bottle can be turned. The opening between the two fingers 302 of the finger empty bottle clamping mechanism 3 is 2°~4° to ensure that there is a gap between the bottleneck and the finger 302 but it will not tilt and fall. During the entire movement process of the finger arm 301, it is in contact with the straight section 101, the "gripper" always remains slightly open, and always maintains the same opening degree of the finger 302; and the distance between the arc section 102 and the end face of the finger arm 301 increases, so that when the finger arm 301 leaves the straight section 101 and moves to the arc section 102, the arc section 102 and the end face of the finger arm 301 are no longer in contact, thereby releasing the contact, and the corresponding finger arm 301 will rotate and reset under the action of the spring to close, clamping the neck of the empty bottle.

[0034] Therefore, in this embodiment, when the finger arm 301 moves to the straight section 101 of the opening and closing abutment member 1, the opening and closing abutment member 1 abuts against the end of the finger arm 301, so that the distance between the clamping fingers 302 becomes larger and opens, and when it moves to the arc section 102, the abutment is released, so that the clamping fingers 302 are reset and clamped. In the process of the empty bottle moving to the opening and closing abutment member 1, the friction steering contact member 2 located on one side of the empty bottle also contacts the empty bottle, rubbing the moving empty bottle, so that the empty bottle is rotated 90 degrees.

[0035] Furthermore, the opening and closing abutment member 1 is in the shape of a strip, and the straight section 101 and the arc section 102 are integrally formed. The opening and closing abutment member 1 also includes a buffer arc section 103, which is connected to one end of the straight section 101 away from the arc section 102, and the distance between the buffer arc section 103 and the end of the finger arm 301 is greater than the distance between the straight section and the end of the finger arm 301. The buffer arc section 103 is an arc-shaped sheet, and there is a certain angle between the buffer arc section 103 and the straight section 101, and an arc chamfer is provided at the connection between the buffer arc section 103 and the straight section 101.

[0036] When the finger empty bottle clamping mechanism 3 moves to the position of the opening and closing abutment 1, since the finger empty bottle clamping mechanism 3 is constantly moving, a certain impact will be generated when it contacts the straight section 101 of the opening and closing abutment 1. In order to buffer the impact, a buffer arc section 103 is provided, which can buffer the impact between the end face of the finger arm 301 and the opening and closing abutment 1, reduce the impact vibration, and extend the service life of the opening and closing abutment 1.

[0037] Furthermore, the steering assist mechanism also includes a mounting seat 4, the opening and closing abutment 1 is fixed on the mounting seat 4, facing the direction of the finger empty bottle clamping mechanism 3, and the mounting seat 4 is fixedly mounted on the base 5 of the blowing and filling line clamping device, and the opening and closing member is fixedly connected to the mounting seat 4 by screws.

[0038] Embodiment 2:

[0039] On the basis of Example 1, Figure 2 , 3 As shown in the figure, the friction steering contact member 2 is set as an arched tube, and the two ends of the arched tube are fixedly connected to the base 5 of the blowing and filling line clamping device, and the arched tube is made of soft material. When the empty bottle contacts the arched tube, the friction between the soft material and the plastic empty bottle is used to rotate the empty bottle from the longitudinal position to the transverse position by 90°. Preferably, the arched tube is made of polyurethane.

[0040] Furthermore, the steering assist mechanism further includes a steering adjustment assembly 6, which includes a fixing screw 601, a connecting nut 602 and a holding ring 603. One end of the fixing screw 601 is fixedly connected to the base 5 of the blowing and filling line clamping device. The fixing screw 601 is located on the side of the friction steering contact member 2 away from the holding member 1. The connecting nut 602 is threadedly sleeved on the fixing screw 601. Both ends of the holding ring 603 are connected to the connecting nut 602. Two groups of the steering adjustment assembly 6 are provided, which are respectively located at both ends of the friction steering contact member 2.

[0041] During operation, the arched tube will be deformed to a certain extent in the long-term friction process. In order to keep the arched tube and the empty bottle in good contact at all times, a steering adjustment component 6 is provided. By rotating the connecting nut 602, the supporting ring 603 can be driven to rotate and move along the fixing screw 601, so that the supporting ring 603 can be brought into contact with the arched tube, and the curvature of the arched tube and the height of the arched top of the arched tube can be adjusted to adjust the contact position and contact area between the arched tube and the empty bottle, thereby realizing a 90° steering of the empty bottle.

[0042] Furthermore, the arc length of the arch tube is preferably set to 300 mm-350 mm, the bending radius R is set to 100 mm ~130 mm, and the adjustment range of the supporting ring 603 is within 40 mm, that is, the supporting ring 603 can be moved along the forward and backward stroke range of the fixing screw 601 within 40 mm, and the length of the fixing screw 601 is preferably 110 mm, and the diameter of the supporting ring 603 is 50 mm, so that the supporting ring 603 and the arch tube can be effectively matched to ensure a 90° steering effect of the empty bottle.

[0043] The above specific implementation methods further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above are only specific implementation methods of the utility model and are not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
