Description

Technical Field

[0001] The invention relates to the technical field of spherical fillers, in particular to a spherical filler capping mechanism. Background Art

[0002] With the vigorous development of the environmental protection industry, the demand for spherical fillers used in the environmental protection industry is increasing. Figure 4 The spherical filler is a two-hemispherical mesh injection molded part. In the normal state, it is formed by two hemispheres that are unfolded 180° and connected. The two hemispherical fillers 100 have multiple buckles on the fitting surface. Put the filler into the closing mechanism and flip the hemisphere on one side 180° to the fitting surface to complete the assembly.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] like Figure 1-3 As shown, a spherical filler closing mechanism according to a preferred embodiment of an embodiment of the present invention comprises two relatively arranged support seats 1, a first mold 2, a second mold 3, a driving mechanism and a pressing assembly, the first mold 2 and the second mold 3 are both provided with a receiving hole 4 for accommodating a hemispherical filler, the edge of the receiving hole 4 is provided with a clamping assembly for clamping the hemispherical filler 100, the first mold 2 is fixedly arranged between the two support seats 1, the second mold 2 is rotatably connected between the two support seats 1, the driving mechanism is used to drive the second mold 3 to rotate around its rotation point to realize the closing of two hemispherical fillers 100, the pressing assembly is arranged above the first mold 2 and the second mold 3, after the two hemispherical fillers 100 are closed, the pressing assembly is pressed downward to realize the separation of the second mold 3 from the spherical filler.

[0027] The spherical filler closing mechanism based on the above technical features is achieved by fixing the first mold 2 between the two support seats 1, and the second mold 3 is rotatably connected between the two support seats 1. At the same time, a driving mechanism is set to drive the second mold 3 to rotate around its rotation point. When closing is required, the two hemispherical fillers 100 are first placed in the two accommodating holes 4 respectively, and then the driving mechanism drives the second mold 3 to rotate. When the second mold 3 is rotated to fit with the first mold 2, the closing of the spherical filler is achieved. Since the hemispherical filler 100 is pressed by the pressing assembly during the closing process, the position of the filler during the closing process and after demolding can be stably controlled to prevent the filler from flying outward, and the closing process of the spherical filler is completed efficiently and accurately, thereby improving production efficiency.

[0028] In this embodiment, a first sensor 5 and a second sensor 6 are respectively provided on any one of the support seats 1 corresponding to the first mold 2 and the second mold 3, and a sensing sheet 7 is provided on the second mold 3, and the sensing sheet 7 cooperates with the first sensor 5 and the second sensor 6 to detect the rotation position of the second mold 3. Specifically, before closing the cover, the first mold 2 and the second mold 3 are 180° apart, and when closing the cover, the second mold 3 rotates. When it rotates 150°, the angle between the two molds is 30°. At this time, the sensing sheet 7 enters the detection range of the first sensor 5, and the feedback signal drives the pressing assembly to separate from the hemispherical filler 100. After separation, the second mold 3 continues to rotate. When the first mold 2 and the second mold 3 bracket are 0°, the pressing assembly is pressed down, and the two hemispherical fillers 100 form a complete spherical filler. When the second mold 3 is reset, it rotates to 150° with the first mold 2, and the sensing sheet 7 enters the detection range of the second sensor 6 until the second mold 3 is completely reset, and the second sensor 6 feedbacks a signal to proceed to the next process.

[0029] In this embodiment, a connecting rod 8 is rotatably connected to the support seat 1, and the second mold 3 is fixed on two connecting rods 8, wherein any one of the connecting rods 8 is connected to the driving mechanism. The driving mechanism drives the connecting rod 8 to drive the second mold 3 to rotate.

[0030] Specifically, a bearing seat 9 is provided on the support seat 1, a bearing is provided in the bearing seat 9, a rotating shaft 10 is inserted in the bearing, and the connecting rod 8 is connected to the rotating shaft 10. The driving mechanism includes a motor 11, and the motor 11 is connected to any one of the rotating shafts 10 through a reducer. The motor 11 and the reducer are directly connected to drive, the transmission structure is simple, and the space occupied is small. The motor 11 is a stepper motor, the stepper motor controls the rotation angle accurately, the mechanism has an angle position feedback, and the various actions of the mechanism during the rotation process are controlled in real time, so that the lid can be closed stably and quickly.

[0031] Please refer to the attached Figure 3In this embodiment, there are four clamping assemblies, two of which are arranged for each mold. The clamping assembly includes a cylinder 12, a pressure claw 13, a cylinder support 14 and a pressure claw support 15. The cylinder support 14 and the pressure claw support 15 are fixed on the lower surface of the first mold 2 and the second mold 3. The cylinder 12 is fixed on the cylinder support 14. The pressure claw 13 includes a connecting portion 16 and a clamping portion 17 connected to each other. The middle part of the pressure claw 13 is hinged with the pressure claw support 15. The telescopic rod of the cylinder 12 is hinged with the connecting portion 16. The first mold 2 and the second mold 3 are both provided with a clamping hole, and the clamping portion 17 is inserted into the clamping hole. When clamping is required, the telescopic rod of the cylinder 12 rises, driving the connecting portion 16 to move up, and the middle part of the pressure claw 13 rotates around its hinge point, driving the clamping portion 17 to press down, so as to achieve the clamping of the hemispherical filler 100; when released, the reverse action is performed.

[0032] In addition, in order to avoid the pressing part 17 of the pressing claw 13 from colliding and interfering with the mold when the cover is closed, a first avoidance groove 18 is provided on one side of the pressing hole of the first mold 2. When the second mold 3 is rotated to fit with the first mold 2, the pressing part 17 on the second mold 3 is inserted into the first avoidance groove 18; a second avoidance groove 19 is provided on one side of the pressing hole of the second mold 3. When the second mold 3 is rotated to fit with the first mold 2, the pressing part 17 on the first mold 2 is inserted into the second avoidance groove 19. By providing the avoidance groove, when the mold is closed, the pressing claw 13 does not need to be completely retracted under the mold, so that the pressing claws 13 on the two molds can be avoided from colliding with the mold, simplifying the structure of the pressing claw and making the structure more stable.

[0033] In this embodiment, the pressing assembly is arranged beside the first mold 2 and the second mold 3, and includes a guide shaft support 20, and the guide shaft support 20 is used to connect to the frame of the filler assembly machine. A support tube 21 is inserted into the guide shaft support 20 so as to be movable up and down, and a cylinder mounting plate 22 is provided at the upper end of the support tube 21, and a pressing cylinder 23 is provided on the cylinder mounting plate 22, and a pressing block 24 is provided on the telescopic rod of the pressing cylinder 23, and the pressing block 24 realizes pressing under the action of the pressing cylinder 23. By designing an independent pressing assembly beside the mold, the spherical material is always stably fixed on the first mold during the demoulding process, preventing the spherical material from flying outward or sticking to the second mold 3, thereby improving the stability and efficiency of demoulding, and providing stability and uniqueness for the subsequent processes of the automatic assembly equipment.

[0034] In this embodiment, a buffer 25 is provided on the upper surface of the first mold 2 to buffer impact when the first mold 2 and the second mold 3 are closed. A support shaft is provided in the middle of the lower surface of the first mold 2 to increase the stability of the first mold 2. A polyurethane buffer column 26 is provided on the lower surface of the second mold 3. When the second mold 3 is reset, the buffer column 26 plays a buffering role to protect the second mold 3.

[0035] The lid closing mechanism of the present invention has a small size and multiple functions. One mechanism can be used for multiple workstations and is suitable for a multi-station rotary automatic lid closing assembly machine. Multiple workstations use the same mechanism, and there is no need to design multiple different workstations to realize different actions in the lid closing process, thus saving manufacturing and assembly costs.

[0036] The working process of the spherical filler provided by the present invention is:

[0037] (1) Open the cover and wait for material to be fed in: The initial state of the mechanism is that the two molds are 180 degrees apart. The lower part of the second mold 3 is supported by an adjustable polyurethane buffer column 26, which can make the two molds 180 degrees apart. At the same time, when the second mold 3 rotates to the initial position, it has a buffering effect on the mold, eliminating collision noise. The opening size and center distance of the two molds are consistent with the spherical material, ensuring that the spherical material can smoothly enter the two molds from the previous process.

[0038] (2) Open the cover and press the material in:

[0039] After the hemispherical filler 100 passes through the previous process and enters the two molds, the four cylinders 12 at the bottom of the two molds are activated, and the four pressing claws 13 are driven by the connecting rod mechanism to press the edge of the hemispherical filler 100 to ensure that the spherical filler is fixed on the mold and the spherical material is stable and motionless during the rotation process.

[0040] (3) The second mold rotates 150° counterclockwise and closes the claws:

[0041] The stepper motor accurately drives the second mold 3 to rotate 150° counterclockwise. At this time, the two molds are 30° apart. The induction sheet 7 simultaneously rotates to the detection range of the first sensor 5, and the claw retraction signal is fed back. The four cylinders are actuated to drive the release of the pressure claw 13 to avoid affecting the closing of the spherical material.

[0042] (4) Close the lid and press the material:

[0043] After the pressing claw 13 is retracted, the stepper motor accurately drives the second mold 3 to continue rotating until the two molds are fitted to each other at 0°, and the spherical material is fastened and fitted by the built-in buckles, and the two semicircles are combined into a spherical whole. The two buffer parts 25 on the first mold 2 can adjust the height, and play a buffering role when closing the cover to eliminate collision noise. The two molds are provided with pressing claw avoidance grooves to prevent the claws from colliding with the molds when closing the cover. The pressing cylinder 23 of the pressing assembly extends downward to press the spherical material.

[0044] (5) Rotate the second mold 30° clockwise and demould:

[0045] The pressing assembly continuously presses the spherical filler to ensure that the filler is on the first mold 2. The stepper motor accurately drives the second mold 3 to rotate 30° clockwise, and the second mold 3 is separated from the spherical filler. At the same time, the induction sheet 7 on the mold turns to the detection range of the second sensor 6 and feeds back a return signal.

[0046] (6) Open the cover and return to the 180° initial position:

[0047] After the pressing assembly receives the return signal, the pressing block returns to avoid collision with the rotating mold. The stepper motor accurately drives the second mold 3 to rotate 150° clockwise and return to the initial position of the second mold 3. The polyurethane buffer column 26 plays a supporting and buffering role. At the same time, the second sensor 6 senses that the second mold 3 is in place and feeds back the signal of the initial position to complete the opening action. The spherical filler is pushed out through the next process.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
