Description

Technical Field

[0001] The utility model belongs to the technical field of demoulding mechanisms, and in particular relates to a lifting, clamping and demoulding mechanism. Background Art

[0002] During the bottle production process, in order to ensure the stability of the bottle when transferring between two adjacent devices, a movable mold base is usually matched at the bottom of the bottle. The bottle is directly placed in the movable mold base. The bottle placed in it can be moved by moving the movable mold base.

[0003] However, after the bottle processing is completed, the movable mold base and the bottle need to be separated so that the movable mold base can be reused. The current common method is manual demoulding, which wastes manpower costs and is inefficient, and also affects the production rhythm of the equipment. However, the use of automated equipment requires consideration of demoulding for different bottle specifications, so the automated demoulding technology for bottles still needs to be improved and optimized. Utility Model Content

[0004] In view of the problems raised by the above background technology, the purpose of the present utility model is to provide a lifting, clamping and demoulding mechanism.

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0025] Example 1:

[0026] like Figure 1 、 Figure 2 、 Figure 3 As shown, a lifting, clamping and demoulding mechanism of the present invention comprises a base frame 1, with lifting mechanisms 2 installed at the four corners of the top of the base frame 1, a short connecting rod 3 connecting the two groups of lifting mechanisms 2 on the left and right sides, and a long connecting rod 4 connecting the two lifting mechanisms 2 on the front side, and a height adjustment hand wheel 5 connected to the power end of one of the lifting mechanisms 2. When the height adjustment hand wheel 5 is rotated, the output ends of the four lifting mechanisms 2 rise and fall synchronously;

[0027] The output ends of the four jacking mechanisms 2 are connected to the frame 6, the output end of the frame 6 is connected to the turning feeding conveyor belt 7, the output end of the frame 6 is connected to the straight feeding conveyor belt 8, the frame 6 is suspended with three mounting brackets 9, the horizontal height of the mounting bracket 9 in the middle is higher than the two mounting brackets 9 on both sides, the three mounting brackets 9 are equipped with a width adjustment mechanism 10 in conjunction with the frame 6, and a clamping conveyor line 11 is installed on the lower side of the three width adjustment mechanisms 10. The input end and output end of the clamping conveyor line 11 correspond to the turning feeding conveyor belt 7 and the straight feeding conveyor belt 8 respectively;

[0028] The width adjustment mechanism 10 includes several right-angle steering gear boxes 101 installed on the frame 6 and a width adjustment seat 102 installed on the lower side of the mounting frame 9. A rotating rod 103 is connected between the several right-angle steering gear boxes 101, and the rotating rod 103 passes through the end of the width adjustment seat 102. The rotating rod 103 is installed with a first bevel gear 104 inside the width adjustment seat 102, and a slide 105 is provided inside the width adjustment seat 102. A positive and negative threaded screw rod 106 is rotatably installed in the slide 105. The threads of the positive and negative threaded screw rod 106 are opposite from the center position to the threads on both sides. The ends of the positive and negative threaded screw rod 106 are fixedly connected to a second bevel gear 107 that meshes with the first bevel gear 104. The two sections of the threads of the positive and negative threaded screw rod 106 are each threadedly connected to a slider 108. The lower ends of the two sliders 108 are each connected to a side conveyor line of the clamping conveyor line 11, and the power end of the rotating rod 103 is connected to a width adjustment hand wheel 109.

[0029] In this embodiment, the bottles in the movable mold base are fed into the frame 6 by the curved feeding conveyor belt 7. When the upper end of the bottle enters the clamping conveyor line 11, the bottle is clamped by the clamping conveyor line 11. Because the middle section of the clamping conveyor line 11 is higher than the two ends, the bottle will be lifted when moving in the clamping conveyor line 11. The movable mold base has its own weight, so the bottle and the movable mold base are automatically demoulded. The movable mold base is moved to the next process by the rotating feeding conveyor belt 7, and the bottle that falls off the movable mold base is clamped by the clamping conveyor line 11 and moved to the straight unloading conveyor belt 8 for placement and then moved to the next process.

[0030] When it is necessary to adjust the distance between the clamping conveyor line 11 and the curved loading conveyor belt 7 and the straight unloading conveyor belt 8 to adapt to the demoulding of bottles of different heights, the height adjustment hand wheel 5 is turned to realize the synchronous operation of the output ends of the four jacking mechanisms 2 at the four corners of the top of the base frame 1, thereby causing the upper frame 6 to rise and fall, and then causing the mounting frame 9 installed thereon to rise and fall, and the clamping conveyor line 11 to rise and fall immediately, thereby achieving the adjustment purpose. It should be noted that the clamping conveyor line 11 for bottles has been produced and put into use in the prior art;

[0031] When it is necessary to adjust the spacing between the two side conveyor lines of the clamping conveyor line 11 to adapt to the clamping of bottles with different bottle diameters, the width adjustment hand wheel 109 is turned to drive the rotating rod 103 to rotate. With the cooperation of multiple right-angle steering gear boxes 101, all the rotating rods 103 located in the width adjustment seat 102 at different heights rotate synchronously in the same direction. The rotation of the rotating rod 103 causes the first bevel gear 104 and the second bevel gear 107 meshing with the first bevel gear 104 to rotate. The rotation of the second bevel gear 107 drives the forward and reverse threaded screw rod 106 to rotate, and then causes the slider 108 threadedly connected to the two screws of the forward and reverse threaded screw rod 106 to move synchronously in the same direction or synchronously in the opposite direction, thereby realizing the distance adjustment between the two sliders 108, thereby realizing the change of the distance between the side conveyor lines installed on the lower side of the slider 108.

[0032] Example 2:

[0033] like Figure 1 As shown, a protective cover 13 is installed on the outside of the frame 6. This design plays a role in dust protection and preventing mechanical injuries;

[0034] In this embodiment, the protective cover 13 preferably uses a transparent protective cover with an inspection door, which can not only provide protection but also allow the operating status of the internal components to be intuitively viewed, and can also facilitate adjustment of the width and height.

[0035] Example 3:

[0036] like Figure 1 、 Figure 2 As shown, the lower end surfaces of the curved loading conveyor belt 7 and the straight unloading conveyor belt 8 do not contact the frame 6. This design provides space for lifting and adjusting.

[0037] In this embodiment, the support of the curved loading conveyor belt 7 and the straight unloading conveyor belt 8 is supported by their own support feet, so it is preferred that the support feet of the curved loading conveyor belt 7 and the straight unloading conveyor belt 8 have a height adjustment function to enhance the adaptation effect with the frame 6.

[0038] Example 4:

[0039] like Figure 1 、 Figure 2As shown, the lifting mechanism 2 is a worm gear screw lift, and a coupling 12 is installed at the position where the lifting mechanism 2 connects the long connecting rod 4 and the short connecting rod 3. The worm gear screw lift is a product that can be directly purchased in the existing technology and can be directly purchased and used. The coupling 12 has the functions of buffering and shock absorption, which can effectively reduce equipment wear and internal noise, and at the same time absorb and buffer the vibration and impact generated by the motor or equipment. The coupling 12 also serves as a safety device to prevent the connected parts from bearing excessive loads and plays a role in overload protection. The coupling 12 can compensate for the offset between the two shafts due to inaccurate manufacturing and installation, deformation during operation or thermal expansion, etc., to ensure stable operation of the equipment.

[0040] In this embodiment, the jacking mechanism has the lifting and lowering adjustment function, and the long connecting rod 4 and the short connecting rod 3 are both power transmission parts, so the fundamental purpose is the synchronous operation of all jacking mechanisms, so the choice of jacking mechanism can be made according to the specific situation.

[0041] Embodiment 5:

[0042] like Figure 1 、 Figure 2 As shown, the front shape of the clamping conveyor line 11 is convex, and this design achieves the purpose of separating the bottle body from the movable mold base during the transfer process.

[0043] In this embodiment, the middle section of the clamping conveyor line 11 is raised upwards to allow the bottle to be lifted, thereby achieving automatic separation from the movable mold base. The specific amount of upward protrusion depends on the specific situation.

[0044] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical principles disclosed herein shall be covered by the claims of the present invention.
