Description

Technical Field

[0001] The present application relates to the technical field of nozzle processing equipment, and in particular to an automatic nozzle cutting machine. Background Art

[0002] In the production process of plastic shell products, the removal of nozzles is an important process. The traditional method is mainly to cut the nozzles manually, which is not only inefficient, but also has unstable cutting quality due to human factors, which can easily lead to product damage or operator injury. With the development of industrial automation technology, some automatic nozzle removal equipment has appeared on the market, which can improve work efficiency and product quality to a certain extent.

[0003] The automatic water outlet cutting machine in the related art includes a machine body, a driving mechanism arranged in the machine body, and a cutter connected to the driving mechanism. A groove for the cutter to move horizontally is provided on the surface of the machine body, and the cutter extends from the groove and exceeds the surface of the machine body. The shell to be processed is placed on the upper surface of the machine body, and the cutter corresponds to the position of the water outlet. The driving mechanism drives the cutter to move so as to remove the water outlet.

[0004] When removing the nozzle of some shells, the shell opening faces downwards, and after it is placed on the machine body, the cutter extends into the inner cavity of the shell, and then the nozzle is removed. However, when the staff places the shell on the machine body, it takes a certain amount of time to make the position of the cutter and the nozzle correspond, and the shell may still be offset after being placed on the machine body, so there is still room for improvement.

[0029] The following is combined with Figure 1-9 This application is described in further detail.

[0030] The present application embodiment discloses an automatic water cutter. Figure 1 and Figure 2 The automatic water outlet cutting machine includes a workbench 3 and a cutter 2 arranged on the workbench 3. After the shell 1 is placed on the workbench 3, the water outlet part in the shell 1 is removed by driving the cutter 2 to move. A positioning mechanism 5 is also installed on the workbench 3. The positioning mechanism 5 is used to position the shell 1 so that when the shell 1 is processed at the water outlet, the position of the water outlet processing can correspond to the cutter 2, and there is no need to manually adjust the position. One or more cutters 2 can be set on the workbench 3; in this embodiment, two cutters 2 are set, that is, the water outlet removal operation can be performed on two shells 1.

[0031] Reference Figure 2 and Figure 3 Two mounting seats 4 are fixed on the upper surface of the workbench 3 on both sides of each cutter 2. The mounting seats 4 are in a long strip structure and are parallel to each other. The positioning mechanism 5 includes a first positioning member 51 respectively mounted on the two mounting seats 4, a second positioning member 52 mounted between the two ends of the two mounting seats 4, and a driving assembly 53 mounted on the workbench 3. A space for placing the shell 1 is enclosed between the two first positioning members 51 and the two second positioning members 52. When the shell 1 is placed in the space, the driving assembly 53 drives the first positioning member 51 to move toward each other and abut against the outer wall of the shell 1, thereby pushing the shell 1 to the middle position between the first positioning members 51 on both sides; the driving assembly 53 continues to drive the second positioning member 52 to move toward each other, and the second positioning member 52 abuts against the other two sides of the shell 1, thereby pushing the shell 1 to the middle position between the two first positioning members 51. While the driving assembly 53 drives the second positioning member 52, the first positioning member 51 can maintain the state of abutting against the shell 1. Therefore, under the action of the first positioning member 51 and the second positioning member 52, the housing 1 is pushed to a predetermined position, at which time the nozzle position can correspond to the cutter 2, and during the nozzle removal process, the first positioning member 51 and the second positioning member 52 can position the housing 1, and the housing 1 is not easily offset. After the nozzle is removed, the driving component 53 drives the first positioning member 51 and the second positioning member 52 to reset, that is, the housing 1 can be removed and a new housing 1 to be processed can be placed.

[0032] Reference Figure 3 and Figure 4The mounting seat 4 is provided with a receiving chamber 6, and the first positioning member 51 includes a rotating ring 511 rotatably mounted in the receiving chamber 6 and a contact rod 512 fixed to the side wall of the rotating ring 511. The upper end surface of the mounting seat 4 is provided with a clearance groove 7 connected to the receiving chamber 6, and the contact rod 512 passes through the clearance groove 7 and exceeds the upper end surface of the mounting seat 4. The driving assembly 53 can drive the rotating ring 511 to rotate, so that the contact rod 512 moves in the clearance groove 7 and contacts the side wall of the shell 1 through the contact rod 512. Figure 5 The upper end of the accommodating chamber 6 is in an arc shape, and the inner wall of the accommodating chamber 6 is provided with an annular groove 32, and the rotating ring 511 is snapped into the annular groove 32, so that the rotating ring 511 can rotate in the inner wall of the accommodating chamber 6 and is not easily offset. In this embodiment, two first positioning members 51 are installed on each mounting seat 4, so that the two sides of the housing 1 are positioned by the two first positioning members 51 respectively, and when the second positioning member 52 positions the housing 1, the housing 1 is less likely to be offset.

[0033] Reference Figure 3 and Figure 5 The driving assembly 53 includes a sliding rod 531 that slides through the rotating ring 511, a pushing rod 532 that slides in the accommodating chamber 6, and a power source 533 for driving the pushing rod 532 to slide. The length directions of the sliding rod 531 and the pushing rod 532 are parallel, and an extension seat 8 is installed on the side wall of the sliding rod 531, and the extension seat 8 extends downward. One end of the pushing rod 532 can abut against the extension seat 8. When the power source 533 drives the pushing rod 532 to slide, the pushing rod 532 can drive the sliding rod 531 to slide through the extension seat 8. The power source 533 is preferably a cylinder fixed on the workbench 3, and the pushing rods 532 in the two mounting seats 4 are both connected to the piston rod of the cylinder, so that the power source 533 can drive the two pushing rods 532 to slide at the same time.

[0034] Reference Figure 3 and Figure 4 An elastic member 11 is installed on the end of the mounting seat 4 away from the power source 533, and the end of the sliding rod 531 is connected to the elastic member 11. When the power source 533 drives the sliding rod 531 to slide, the elastic member 11 is compressed. When the power source 533 drives the push rod 532 to reset, the elastic member 11 can drive the sliding rod 531 to reset. The elastic member 11 is a spring, and a cylinder 29 is fixed on the end surface of the mounting seat 4 to provide a space for spring installation. The end of the sliding rod 531 is connected to one end of the spring.

[0035] Reference Figure 4The inner wall of the rotating ring 511 is fixed with a protrusion 10, which is preferably a cylindrical structure. The side wall of the sliding rod 531 is provided with a limiting groove 9, which extends obliquely along the circumference of the sliding rod 531. The protrusion 10 extends in the limiting groove 9. When the push rod 532 drives the sliding rod 531 to slide, the rotating rings 511 on the two mounting seats 4 move toward each other, so that the abutting rod 512 can abut on both sides of the housing 1. When the elastic member 11 drives the sliding rod 531 to reset, it also drives the rotating ring 511 to reset.

[0036] Reference Figure 3 The second positioning member 52 includes a rotating rod 521 rotatably connected between the two ends of the two mounting seats 4 and an extension rod 522 fixed to the side wall of the rotating rod 521, and the side wall of the rotating rod 521 can fix the two extension rods 522. The rotating rod 521 is rotatably connected to the side wall of the mounting seat 4 by means of a bearing or the like, and one end of the rotating rod 521 extends into the accommodating cavity 6.

[0037] Reference Figure 5 and Figure 6 The inner wall of the accommodating chamber 6 is rotatably connected to two connecting rods 12, and the two connecting rods 12 are located in the middle position near the mounting seat 4. One end of the rotating rod 521 extending into the accommodating chamber 6 is connected to the adjacent connecting rods 12 with a synchronous belt 13, so that the connecting rods 12 and the rotating rods 521 can be synchronously driven. In order to improve the driving effect of the synchronous belt 13, a synchronous wheel can be used for connection.

[0038] One of the connecting rods 12 is linked to the push rod 532, and the push rod 532 can drive the connecting rod 12 to rotate. The outer walls of the two connecting rods 12 are coaxially fixed with meshing gears 14, and the two meshing gears 14 mesh with each other. Therefore, the push rod 532 drives one of the connecting rods 12 to rotate, that is, the two connecting rods 12 can be driven to rotate toward each other, and then the two extension rods 522 can be driven to rotate toward each other, so that the extension rods 522 can abut against the two sides of the housing 1.

[0039] The lower surface of the push rod 532 is evenly provided with teeth 15, and a linkage gear 16 is coaxially fixed to the outer wall of one of the connecting rods 12. When the teeth 15 and the linkage gear 16 are meshed, the connecting rod 12 can be driven to rotate.

[0040] After the first positioning member 51 abuts against the side wall of the housing 1 , the push rod 532 continues to move to drive the second positioning member 52 to move. Therefore, after the rotating ring 511 rotates, the sliding rod 531 cannot affect the push rod 532 to continue to drive the connecting rod 12 to rotate.

[0041] Reference Figure 5 and Figure 7The extension seat 8 is connected to the side wall of the sliding rod 531 for sliding upward and downward sliding. The side wall of the sliding rod 531 is provided with a sliding groove 20 for sliding the extension seat 8. The extension seat 8 and the inner wall of the accommodating chamber 6 are linked so that when the push rod 532 pushes the sliding rod 531 to slide, the extension seat 8 can gradually slide upward.

[0042] Reference Figure 5 and Figure 8 , the upper surface of the end of the push rod 532 close to the extension seat 8 has a stepped cavity 19, and the position of the stepped cavity 19 is slidably installed with a resistance block 17. The push rod 532 is correspondingly provided with a receiving groove 30 for the resistance block 17 to slide, one end of the resistance block 17 is located in the receiving groove 30, and the other end extends out. A reset member 18 is installed in the receiving groove 30, and the reset member 18 is a spring, one end of which is connected to the inner end surface of the receiving groove 30, and the other end is connected to the end surface of the resistance block 17. When the end of the push rod 532 abuts against the extension seat 8, in the process of the push rod 532 pushing the sliding rod 531 to slide, the extension seat 8 can gradually slide upward, and when the extension seat 8 and the push rod 532 are separated, the resistance block 17 can abut against the extension seat 8, and the push rod 532 continues to move forward, and the resistance block 17 is relatively pressed into the receiving groove 30. At this time, the housing 1 is positioned by the abutment rods 512 on both sides. The push rod 532 continues to move, and the teeth 15 begin to cooperate with the meshing gear 14 to drive the connecting rod 12 to rotate, thereby driving the rotating rod 521 to rotate. Further, in order to facilitate the separation of the extension seat 8 and the end of the push rod 532, the end of the push rod 532 is provided with an inclined surface 28 inclined downward.

[0043] Reference Figure 6 and Figure 7 The side wall of the extension seat 8 is symmetrically fixed with a guide block 21, which is a cylindrical structure. The inner wall of the accommodating cavity 6 is provided with a guide groove 22, which is inclined upward toward the direction close to the elastic member 11, and the guide block 21 extends in the guide groove 22. When the push rod 532 pushes the extension seat 8 to move, the extension seat 8 can gradually slide upward into the sliding groove 20 and gradually separate from the push rod 532.

[0044] In a further embodiment, referring to Figure 4 and Fig. 9, a mounting groove 23 is provided in the abutting rod 512, and the mounting groove 23 passes through to the end of the abutting rod 512. A reinforcing rod 24 is slidably inserted in the mounting groove 23. A return member 25 is connected between the end of the reinforcing rod 24 and the inner end surface of the mounting groove 23, and the return member 25 is a spring. One end of the spring is connected to the inner end surface of the mounting groove 23, and the other end is connected to the end surface of the reinforcing rod 24. Under the action of the spring, the reinforcing rod 24 is received in the mounting groove 23. An elastic block is fixed to one end of the reinforcing rod 24 near the opening of the mounting groove 23, and the elastic block can be made of rubber or other materials. The rotating rod 521 and the reinforcing rod 24 can be linked to each other. When the rotating rod 521 rotates, the reinforcing rod 24 is driven to slide out of the mounting groove 23, and the elastic block can abut against the side wall of the shell 1, thereby further positioning the shell 1. At this time, the return member 25 is in a stretched state, thereby providing a force for the reinforcing rod 24 to reset.

[0045] The side wall of the abutment rod 512 is provided with a slot 26 connected to the mounting slot 23, and the side wall of the reinforcement rod 24 is provided with a fixed support rod 27, which extends from the slot 26. The side wall of the rotating rod 521 is fixed with a contact rod 31, which is a round rod. When the rotating rod 521 rotates, the contact rod 31 is driven to move, and the contact rod 31 contacts the support rod 27, and pushes the reinforcement rod 24 to slide through the support rod 27, so that the end of the reinforcement rod 24 slides out and contacts the side wall of the housing 1.

[0046] The implementation principle of an automatic water outlet cutting machine in the embodiment of the present application is as follows: the housing 1 is placed on the workbench 3, and then the housing 1 is positioned at the middle position between the two first positioning members 51 through the first positioning member 51, and then the housing 1 is positioned between the two second positioning members 52 through the second positioning member 52, at which time the water outlet position of the housing 1 corresponds to the position of the cutter 2. During the water outlet removal process, the first positioning member 51 and the second positioning member 52 can also simultaneously position the housing 1, so that the housing 1 is not easily offset.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
