Description

Technical Field

[0001] The present invention relates to the technical field of container shaping and processing, in particular to a device for shaping and processing curved surfaces of glass containers. Background Art

[0002] The double-layer glass cup consists of an inner cup and an outer cup. Its unique structure gives it the advantages of heat preservation, cold preservation, scalding prevention and durability. The molding process of the double-layer glass cup mainly includes molding, edge melting, embossing, annealing and quality inspection steps. Among them, the edge melting and embossing steps determine the functionality and durability of the glass cup in the production process.

[0003] At present, when performing edge melting and embossing operations, the outer cup and the inner cup are usually clamped separately by a manual operation using existing clamping equipment, and the rims of the outer cup and the inner cup are heated by existing hot melting equipment (such as a glass hot melting machine). After the heating is completed, the inner and outer cups are rotated synchronously, and then the rim of the inner cup is expanded to make it close to the outer cup, and the edge melting operation is performed. After the edge melting is completed, the above-mentioned expansion effect is released, and the fused edge area is embossed using an existing embossing mold. At this point, the required steps are completed. The changing state between the outer cup and the inner cup can be seen in the figure. Figure 7 .

[0004] The above operation process has the following problems: 1. The clamping process of the inner cup and the outer cup is carried out separately. Therefore, after the inner cup is placed into the outer cup, the axis reference between the two is not defined. As a result, during processing, the position deviation of the inner cup and the outer cup may lead to poor edge melting effect and affect the aesthetics.

[0005] 2. During the edge melting operation, the rims of the inner and outer cups are both in a softened state. At this time, the outward expansion effect is mainly applied to the rim of the inner cup, and the outer cup has no corresponding restrictive effect. As a result, the edge melting effect of the inner and outer cups is uncontrollable, which can easily lead to poor edge melting effects due to the softened state and the lack of restrictive effect of the outer cup. Secondly, the softened inner and outer cups are prone to deformation during operation, affecting the aesthetic effect of the shape and the processing quality. Summary of the Invention

DETAILED DESCRIPTION

[0033] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a glass container curved surface shaping processing device is used in conjunction with an existing machine tool platform and a glass hot-melt machine, wherein the chuck 1 is arranged at the right position of the machine tool platform, the tailstock 2 is arranged at the left position of the machine tool platform, and the glass hot-melt machine is arranged on the machine tool platform and is located between the chuck 1 and the tailstock 2. The processing device includes: a clamping mechanism 5, a clamping mechanism 5 is commonly provided between the chuck 1 and the tailstock 2, and the outer cup 3 is clamped by multiple claws on the chuck 1, and a movable column 50 with an axis extending left and right is rotatably provided on the tailstock 2, and a clamping portion 51 for clamping the inner cup 4 is provided on the movable column 50.

[0035] The clamping mechanism 5 also includes a coaxial part 52 that makes the axis of the inner cup 4 and the axis of the outer cup 3 collinear and is arranged on the machine tool platform. The coaxial part 52 includes two reference columns 520 whose axes extend left and right and are symmetrical front and back. The two ends of the reference column 520 are respectively connected to the chuck 1 and the clamping part 51. The chuck 1 and the clamping part 51 form a rectangular frame through the front and rear two reference columns 520 to ensure that the axes of the inner cup 4 and the outer cup 3 are collinear.

[0036] like Figure 1 、 Figure 2 、 Figure 3 and Figure 6 As shown, the two reference columns 520 and the movable column 50 are jointly provided with a processing mechanism 6, the processing mechanism 6 includes a movable seat 60, the movable seat 60 is provided on the movable column 50 for left and right sliding sleeves, and the upper and lower end surfaces of the movable seat 60 are both installed with arc plates 61 with inner arc surfaces facing the movable column 50, and the two reference columns 520 are jointly provided with left and right sliding sleeves for left and right sliding sleeves, the V-shaped frame 62 is provided with an embossing part 63 and a pressing plate 64, and the V-shaped frame 62 is provided with a transposition part, through which the embossing part 63 and the pressing plate 64 are switched up and down to adapt to the edge melting operation and embossing operation.

[0037] like Figure 1 and Figure 6 As shown, the movable seat 60 is provided with a switching portion 65 , which controls the arc plate 61 to switch between an inclined state and a horizontal state, wherein the inclined state is inclined from right to left in a direction away from the movable column 50 .

[0038] In the inclined state, the upper arc plate 61 and the pressing plate 64 cooperate with each other to melt the edges of the inner cup 4 and the outer cup 3. In the horizontal state, the upper arc plate 61 and the embossing part 63 cooperate with each other to emboss the melted edge parts of the inner cup 4 and the outer cup 3.

[0039] It should be additionally noted that a motor (not shown in the figure) is provided on the left side of the tailstock 2 , and the motor drives the movable column 50 to rotate synchronously through existing transmission technology (such as sprocket transmission, gear transmission and belt transmission, etc.).

[0040] During operation, the outer cup 3 is first manually installed on the chuck 1, and the chuck 1 on it forms an external clamp on the outer cup 3. Then the inner cup 4 is installed on the movable column 50, so that the movable column 50 drives the clamping part 51 to enter the inner cup 4, and the inner cup 4 is internally stretched and clamped by the clamping part 51. At this time, the axis of the outer cup 3 and the axis of the inner cup 4 use the axis of the movable column 50 as the intermediate reference. During the left and right movement of the inner cup 4, the axis of the inner cup 4 and the axis of the outer cup 3 always remain collinear.

[0041] The tailstock 2 drives the inner cup 4 to move right, so that the cup openings of the inner cup 4 and the outer cup 3 are both located above the glass hot-melt machine. The motor and the spindle box and the motor in the machine tool platform operate synchronously, so that the chuck 1 drives the outer cup 3 and the moving column 50 drives the inner cup 4 to rotate synchronously, and the cup openings of the outer cup 3 and the cup openings of the inner cup 4 are heated synchronously.

[0042] After the rims of the outer cup 3 and the inner cup 4 are heated, the tailstock 2 moves to the right so that the bottoms of the outer cup 3 and the inner cup 4 touch each other. At this time, the rims of the two cups are aligned. Then, the switching part 65 is used to make the arc plate 61 in an inclined state, and the pressing plate 64 is located on the lower side. At this point, the edge melting operation begins: the movable seat 60 is moved to the right by manual pushing or external electric guide rod pushing, and the arc plate 61 and the pressing plate 64 are moved to the right synchronously. At this time, the outer cup 3 and the inner cup 4 are located between the upper arc plate 61 and the pressing plate 64. As the arc plate 61 initially moves to the left, the rim area of ​​the inner cup 4 gradually approaches the rim of the outer cup 3, and finally the rims of the two cups begin to fuse. The upper arc plate 61 gradually squeezes the rim area in an inclined state and the pressing plate 64 cooperates to improve the edge melting effect of the cup rim.

[0043] After the edge melting is completed, the movable seat 60 moves to the left, and the switching part 65 works to adjust the curved plate 61 to a horizontal state. At the same time, the position conversion part adjusts the upper and lower positions of the embossing part 63 and the pressing plate 64 so that the two are interchanged up and down. At this point, the embossing operation begins: the embossing part 63 moves downward to press the fused cup mouth onto the upper curved plate 61, and forms the desired texture on the cup mouth, thus completing the shaping process of the container.

[0044] In summary, the two operating states of the upper curved plate 61 are adapted to the edge melting operation and the embossing operation respectively. Secondly, the lower curved plate 61 provides auxiliary support for the cup mouth during the two operating processes, reducing the problem of collapse caused by softening of the cup mouth area after heating, which affects the plastic shape. The pressing plate 64 assists the hot melting process of the inner cup 4 and the outer cup 3 to ensure that the cup mouths of the two are fully fused.

[0045] like Figure 1 、 Figure 2 and Figure 3 As shown, the clamping portion 51 includes a fixing sleeve 510 , and the right end of the movable column 50 is provided with a fixing sleeve 510 . The fixing sleeve 510 is provided with a plurality of circumferentially distributed sliding blocks 511 for radial sliding. A support plate 512 is fixedly provided on the outer side of the sliding block 511 .

[0046] A threaded rod 513 is provided on the movable column 50 for rotation, and a round table 515 with a smaller right side and a larger left side is provided in the fixed sleeve 510 for left and right sliding. A driving ring 514 is provided on the threaded rod 513 for threading. The driving ring 514 is fixedly connected to the round table 515, and the end of the sliding block 511 close to the round table 515 is a wedge-shaped surface that fits with its circumferential surface.

[0047] By manually rotating the threaded rod 513 , all the opening plates 512 are opened to clamp the inner cup 4 , and by manually operating the clamping claws on the chuck 1 , the outer cup 3 is clamped externally.

[0048] During operation, the outer cup 3 is manually installed on the chuck 1, and the outer clamping of the outer cup 3 is formed by the claws on it. Then the inner cup 4 is installed on the movable column 50, so that the movable column 50 drives the clamping part 51 to enter the inner cup 4. The threaded rod 513 is manually rotated, and the cooperation between the threaded rod 513 and the drive ring 514 makes the drive ring 514 drive the round table 515 to move right synchronously through the sliding block 511. The cooperation between the circumferential surface of the round table 515 and the sliding block 511 makes the sliding block 511 drive the expansion plate 512 away from the fixed sleeve 510. At this point, all the expansion plates 512 cooperate with each other to expand and clamp the inner cup 4.

[0049] like Figure 1 and Figure 2 As shown, the coaxial portion 52 further includes a fixing frame 521 . The fixing frames 521 are fixedly provided on both the front and rear sides of the machine tool platform, and the reference column 520 is fixedly provided on the fixing frame 521 .

[0050] A rotating disk 522 is fixedly sleeved on the movable column 50, and two front-to-back symmetrical sliding frames 523 are slidably provided on the circumferential surfaces of the chuck 1 and the rotating disk 522. The sliding frame 523 on the chuck 1 is fixedly sleeved on the corresponding reference column 520, and the sliding frame 523 on the rotating disk 522 is slidably sleeved left and right on the corresponding reference column 520.

[0051] A rectangular frame is formed by the chuck 1, the rotating disk 522 and the reference columns 520 on the front and rear sides to ensure that the axis of the outer cup 3 on the chuck 1 and the axis of the inner cup 4 corresponding to the rotating disk 522 are always collinear during the left and right movement of the inner cup 4, thereby improving the stability during processing while improving the processing accuracy, and avoiding the problem of large deviation between the axis of the inner cup 4 and the axis of the outer cup 3 affecting the cup edge melting effect and embossing effect, as well as affecting the aesthetics.

[0052] like Figure 1 、 Figure 2 and Figure 4 As shown, the processing mechanism 6 also includes a movable frame 66. The left and right sliding sleeves on the reference column 520 are provided with a movable frame 66 located on the right side of the V-shaped frame 62. The movable seat 60 is fixedly connected to the movable frame 66. The movable frame 66 and the V-shaped frame 62 are fixedly connected via a connecting sleeve.

[0053] like Figure 5 and Figure 6 As shown, U-shaped frames 67 are provided on both upper and lower end surfaces of the movable seat 60 for sliding up and down. The two U-shaped frames 67 are symmetrical up and down. The horizontal section of the U-shaped frame 67 is fixed with a fixed shaft 68 extending forward and backward along the axis away from the end surface of the movable seat 60. The arc-shaped plate 61 is rotatably provided on the fixed shaft 68. The U-shaped frame 67 is provided with a locking portion 69 for locking its height.

[0054] like Figure 5 and Figure 6 As shown, the locking portion 69 includes a bolt 690, and bolts 690 extending forward and backward along the axis are fixedly provided on the opposite back surfaces of the two vertical sections of the U-shaped frame 67. A sliding groove 691 for accommodating the bolt 690 is provided on the movable seat 60. The U-shaped frame 67 is locked by tightening the nut onto the bolt 690, thereby finally locking the height of the arc plate 61.

[0055] Before processing the container, the height of the arc plate 61 is manually adjusted according to the size of the inner cup 4 to be processed, and the height of the U-shaped frame 67 is adjusted based on the position where the arc plate 61 needs to fit in with the embossed cup mouth area of ​​the inner cup 4 when in a horizontal state. The upper U-shaped frame 67 is adjusted by tightening the nut, and the lower U-shaped frame 67 is moved symmetrically and locked with reference to the adjustment position of the upper U-shaped frame 67. In summary, it is easy to adapt to the processing requirements of inner cups 4 and outer cups 3 of different sizes, and improve the practicality of the device.

[0056] like Figure 1 、 Figure 5 and Figure 6As shown, the switching portion 65 includes a spiral spring 650. Two spiral springs 650 extending forward and backward are fixedly disposed between the fixed shaft 68 and the curved plate 61. A winding device 651 is fixedly disposed on the front movable frame 66. A secondary rope 652 is fixedly disposed on the opposing surfaces of the two curved plates 61. The other ends of the two secondary ropes 652 are fixedly disposed with a main rope 653 that passes through the movable frame 66 and is wound around the winding device 651. The winding action of the winding device 651 changes the angle of the curved plate 61.

[0057] like Figure 1 and Figure 6 As shown, the switching portion 65 further includes a reference plate 654 , and reference plates 654 are fixedly provided on both left and right end surfaces of the horizontal section of the U-shaped frame 67 , and the vertical length of the right reference plate 654 is smaller than that of the left reference plate 654 .

[0058] like Figure 1 and Figure 4 As shown, the transposition part includes a switching shaft, and a switching shaft with an axis extending left and right is rotated on the V-shaped frame 62 by the lifting block that slides up and down. The lifting block is driven by an electric push rod to move up and down, and a switching plate 655 is fixedly sleeved on the switching shaft. The switching shaft is connected to the switching motor installed on the lifting block. When the switching motor works, the embossing part 63 and the pressing plate 64 are switched up and down, corresponding to the edge melting operation and the embossing operation respectively. The embossing part 63 is rotatably set on the upper side of the switching plate 655 through the installation shaft, and the pressing plate 64 is fixedly set on the lower side of the switching plate 655. The embossing part 63 is composed of an embossing section and a flushing section from right to left. In order to press the cup mouth while embossing, the flushing section is parallel to the arc plate 61 in the horizontal state.

[0059] During operation, in the initial state, the arc plate 61 is in an inclined state, and the edge melting operation is performed in this state. After the edge melting operation is completed, the arc plate 61 needs to be switched to a horizontal state. The specific operation is as follows: the winding device 651 works to wind the main rope 653, and the main rope 653 pulls the two auxiliary ropes 652 and makes the left ends of the two arc plates 61 close to the movable column 50. The arc plate 61 gradually changes from an inclined state to a horizontal state, and then performs an embossing operation. The above process causes the vortex spring 650 to deform. When the subsequent winding device 651 resets and releases the main rope 653, the arc plate 61 resets under the elastic force generated by the deformation of the vortex spring 650, which is convenient for the subsequent edge melting operation. The main rope and the auxiliary rope are both made of high-temperature resistant material. Compared with the method of directly driving the arc plate to rotate by the motor, the method of driving the arc plate to rotate by winding the main rope and the auxiliary rope avoids the problem of the motor entering the high-temperature cup mouth area and causing damage to the motor.

[0060] Secondly, it should be additionally explained that the reference plate 654 on the right side contacts the corresponding arc plate 61, so that the arc plate 61 maintains an inclined state from left to right toward the moving column 50 at this time, and the reference plate 654 on the left side contacts the corresponding arc plate 61, so that the arc plate 61 maintains a horizontal state at this time.

[0061] like Figure 4 and Figure 6 As shown, the lower end surface of the pressing plate 64 is curved, and its curvature is the same as the circumferential curvature of the outer cup 3. During the edge melting operation, the electric push rod operates to drive the pressing plate 64 downward via the lifting block, so that the curved plate 61 of the pressing plate 64 is aligned with the curved surface of the outer cup 3, improving the edge melting effect. It should be noted that the pressing plate 64 and the embossed member 63 are both detachable, which facilitates the processing requirements of containers of different sizes.

[0062] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings.
