Description

Technical Field

[0001] This invention belongs to the field of rubber production technology, specifically a filling equipment for the production of organosilicon rubber. Background Technology

[0002] Currently, silicone rubber is divided into two types: solid and liquid. When producing liquid silicone rubber, filling equipment is needed to fill the liquid silicone rubber into the corresponding containers for subsequent storage and sales.

[0003] In existing technologies, when filling liquid silicone rubber using filling equipment, it is often necessary to manually adjust the position of the container to ensure it is accurately positioned below the filling nozzle. Then, the solenoid valve on the filling nozzle is manually activated to allow the liquid silicone rubber in the storage tank to be sprayed into the container, thus completing the filling operation. It is evident that this filling method requires excessive manual intervention, cannot achieve continuous automatic filling of liquid silicone rubber, and suffers from low filling efficiency, which urgently needs improvement. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a filling equipment for the production of silicone rubber.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A filling device for producing silicone rubber includes a filling table, a tray, a storage cylinder, a material handling assembly, a drive assembly, and a pumping assembly. The tray is rotatably mounted on the upper part of the filling platform to provide support for several containers used to hold liquid silicone rubber. A support plate is fixedly installed on the upper part of the filling platform at the edge of the holding tray. The storage cylinder is fixedly installed on the side wall of the support plate. Liquid silicone rubber is stored inside the storage cylinder. The material handling assembly is rotatably arranged below the storage cylinder. The drive assembly is mounted on the side wall of the support plate and is used to drive the holding tray and the material handling assembly to rotate intermittently. When the holding tray rotates intermittently, it is used to sequentially transfer several containers to a position below the material handling assembly. The pumping component is disposed inside the material taking component. When the material taking component and the holding tray remain stationary, the pumping component is used to draw the liquid silicone rubber inside the storage cylinder into the material taking component, and to press the liquid silicone rubber inside the material taking component into the container below.

[0006] As a further improvement of the present invention: the driving assembly includes a ring gear, a rotating wheel, an arc-shaped rack, and a motor. The motor is fixedly mounted on the side wall of the bracket plate, the wheel is located at the output end of the motor, the annular gear ring is fixedly located on the upper edge of the holding tray, and the arc-shaped rack is fixedly mounted on the circumferential side wall of the wheel and can intermittently mesh with the annular gear ring.

[0007] As a further improvement of the present invention: a feeding pipe is provided at the bottom of the storage cylinder. The material handling assembly includes a material handling wheel and a rectangular frame plate. The rectangular frame plate is fixedly mounted on one side of the support plate, and the material-collecting wheel is disposed inside the rectangular frame plate. A rotating shaft is fixedly mounted at one end of the material-collecting wheel, passing through the rectangular frame plate and rotatably engaging with it. The bottom of the feeding pipe is in contact with the circumferential sidewall of the material-collecting wheel. Two sets of storage cavities are provided inside the material-collecting wheel, symmetrically distributed about the center of the wheel. Two sets of through holes are provided on the circumferential sidewall of the material-collecting wheel, communicating with the two sets of storage cavities respectively. The arc-shaped racks are provided in two sets at intervals on the circumferential sidewall of the wheel, and the drive assembly also includes gears. Both sets of arc-shaped racks can intermittently mesh with the annular gear ring and the gears.

[0008] As a further improvement of the present invention: the pumping assembly includes a piston and a connecting rod. The piston is provided in two sets, and the two sets of pistons are respectively movably disposed inside the two sets of storage cavities. One end of the connecting rod extends into the storage cavity of one set and is fixedly connected to the piston in that storage cavity, and the other end extends into the storage cavity of the other set and is fixedly connected to the piston in that storage cavity.

[0009] As a further improvement of the present invention: a limiting wheel is fixedly installed on the inner wall of the rectangular frame plate, and the limiting wheel has vertically distributed grooves. The material taking wheel has a sliding groove on the side away from the rotating shaft, and a sliding rod is fixedly installed on the side wall of the connecting rod. The end of the sliding rod away from the connecting rod extends from the sliding groove to the outside of the material taking wheel and acts on the circumferential side wall of the limiting wheel.

[0010] As a further improvement of the present invention: the bottom of the feeding pipe is configured with an arc-shaped structure that matches the circumferential sidewall of the feeding wheel.

[0011] As a further improvement of the present invention: the upper edge of the holding tray is provided with a plurality of slots for containers to be inserted, and the plurality of slots are distributed in a ring at equal intervals.

[0012] Compared with the prior art, the beneficial effects of the present invention are: In this embodiment of the invention, when a filling operation is required for liquid silicone rubber, the drive component can drive the holding tray and the picking component to rotate intermittently. At the same time, a robotic arm is used to place several containers for holding liquid silicone rubber in sequence at the upper edge of the holding tray. When the holding tray rotates intermittently, it drives several containers to rotate intermittently in sync, thereby transferring several containers in sequence to the position below the picking component. When the picking component and the holding tray remain stationary, the pumping component located inside the picking component draws the liquid silicone rubber from the storage cylinder into the picking component and presses the liquid silicone rubber inside the picking component into the container below. In this way, a continuous automatic filling operation of liquid silicone rubber can be realized. Compared with the prior art, it can realize automatic continuous filling of liquid silicone rubber without much manual intervention, and has the advantages of good filling effect and high filling efficiency.

Detailed Implementation

[0014] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0015] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0016] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 This embodiment provides a filling device for producing silicone rubber, including a filling platform 10, a holding tray 20, a storage cylinder 30, a material handling component 40, a driving component 50, and a pumping component 60. The holding tray 20 is rotatably mounted on the upper part of the filling platform 10 to provide support for several containers for holding liquid silicone rubber. A support plate 101 is fixedly mounted on the upper part of the filling platform 10 at the edge of the holding tray 20. The storage cylinder 30 is fixedly mounted on the side wall of the support plate 101 and contains liquid silicone rubber. The material handling component 40 is rotatably mounted below the storage cylinder 30. The drive assembly 50 is disposed on the side wall of the support plate 101 and is used to drive the holding tray 20 and the picking assembly 40 to rotate intermittently. When the holding tray 20 rotates intermittently, it is used to transfer several containers to the position below the picking assembly 40 in sequence. The pumping assembly 60 is disposed inside the picking assembly 40. When the picking assembly 40 and the holding tray 20 remain stationary, the pumping assembly 60 is used to draw the liquid silicone rubber inside the storage cylinder 30 into the picking assembly 40 and press the liquid silicone rubber inside the picking assembly 40 into the container below.

[0017] When filling liquid silicone rubber is required, the drive component 50 can drive the holding tray 20 and the picking component 40 to rotate intermittently. At the same time, a robotic arm can be used to place several containers for holding liquid silicone rubber in sequence at the upper edge of the holding tray 20. When the holding tray 20 rotates intermittently, it drives several containers to rotate intermittently in sync, thereby transferring several containers in sequence to the position below the picking component 40. When the picking component 40 and the holding tray 20 remain stationary, the pumping component 60 located inside the picking component 40 draws the liquid silicone rubber inside the storage cylinder 30 into the picking component 40 and presses the liquid silicone rubber inside the picking component 40 into the container below. In this way, continuous automatic filling operation of liquid silicone rubber can be realized.

[0018] Please see Figure 3 as well as Figure 6 In one embodiment, the drive assembly 50 includes an annular gear ring 501, a rotating wheel 502, an arc-shaped rack 503, and a motor 505. The motor 505 is fixedly mounted on the side wall of the support plate 101. The rotating wheel 502 is disposed at the output end of the motor 505. The annular gear ring 501 is fixedly disposed on the upper edge of the holding tray 20. The arc-shaped rack 503 is fixedly mounted on the circumferential side wall of the rotating wheel 502 and can intermittently mesh with the annular gear ring 501.

[0019] The motor 505 drives the rotating wheel 502 to rotate, which in turn drives the arc-shaped rack 503 to rotate. When the arc-shaped rack 503 meshes with the ring gear 501, it can drive the holding tray 20 to rotate. When the arc-shaped rack 503 disengages from the ring gear 501, the holding tray 20 remains stationary. Through the intermittent meshing of the arc-shaped rack 503 and the ring gear 501, the holding tray 20 and several containers located on the upper edge of the holding tray 20 can be rotated intermittently, thereby transferring several containers to the position below the material handling component 40 in sequence.

[0020] Please see Figure 1 , Figure 4 as well as Figure 5 In one embodiment, the storage cylinder 30 has a feeding pipe 301 at its bottom, and the material picking assembly 40 includes a picking wheel 401 and a rectangular frame plate 402. The rectangular frame plate 402 is fixedly disposed on one side of the support plate 101, and the picking wheel 401 is disposed inside the rectangular frame plate 402. A rotating shaft 403 is fixedly disposed at one end of the picking wheel 401. The rotating shaft 403 passes through the rectangular frame plate 402 and rotates in cooperation with the rectangular frame plate 402. The bottom of the feeding pipe 301 is in contact with the circumferential side wall of the picking wheel 401. The material taking wheel 401 has two sets of storage cavities 405 inside, which are centrally symmetrical about the material taking wheel 401. The material taking wheel 401 has two sets of through holes 404 on its circumferential sidewall, which are respectively connected to the two sets of storage cavities 405. The arc-shaped rack 503 has two sets spaced apart on the circumferential sidewall of the rotating wheel 502. The drive assembly 50 also includes a gear 504. Both sets of arc-shaped racks 503 can intermittently mesh with the annular gear ring 501 and the gear 504.

[0021] When the rotary wheel 502 rotates, it drives two sets of arc-shaped racks 503 to rotate. When one set of arc-shaped racks 503 meshes with the ring gear 501, thereby driving the holding tray 20 to rotate, the other set of arc-shaped racks 503 meshes with the gear 504, thereby driving the rotating shaft 403 and the picking wheel 401 to rotate. When one set of arc-shaped racks 503 disengages from the ring gear 501, keeping the holding tray 20 stationary, the other set of arc-shaped racks 503 disengages from the gear 504, thereby causing the picking wheel 401 to rotate. When the tray 20 remains stationary and the picking wheel 401 is stationary, the two sets of storage chambers 405 and the two sets of through holes 404 are vertically distributed. At this time, the pumping component 60 is activated to draw the liquid silicone rubber inside the storage cylinder 30 into the upper storage chamber 405 through the upper through hole 404, and at the same time, to press the liquid silicone rubber inside the lower storage chamber 405 into the container below the picking wheel 401 through the lower through hole 404, thereby realizing the picking and filling operation of liquid silicone rubber.

[0022] Please see Figure 4 In one embodiment, the pumping assembly 60 includes a piston 601 and a connecting rod 602. The piston 601 is provided in two sets, and the two sets of pistons 601 are respectively movably disposed inside the two sets of storage cavities 405. One end of the connecting rod 602 extends into the interior of one set of storage cavities 405 and is fixedly connected to the piston 601 in that storage cavity 405, and the other end extends into the interior of the other set of storage cavities 405 and is fixedly connected to the piston 601 in that storage cavity 405.

[0023] When the picking wheel 401 remains stationary and the two sets of storage chambers 405 are vertically distributed, the two sets of pistons 601 and connecting rods 602 move downward under the action of gravity. When the piston 601 located inside the upper storage chamber 405 moves downward, it draws the liquid silicone rubber inside the storage cylinder 30 into the upper storage chamber 405 through the upper through hole 404. When the piston 601 located inside the lower storage chamber 405 moves downward, it pushes out the liquid silicone rubber in the lower storage chamber 405 through the lower through hole 404, so that the liquid silicone rubber is filled into the container located below the picking wheel 401.

[0024] When the material-receiving wheel 401 rotates, causing the two sets of storage chambers 405 to be in an inclined state, the two sets of pistons 601 and connecting rods 602 will also be affected by gravity and move downwards. At this time, since the two sets of storage chambers 405 have not rotated to a vertical distribution state, when the downward-moving pistons 601 squeeze out the liquid silicone rubber inside the lower storage chamber 405, the squeezed liquid silicone rubber may not accurately enter the container, thus affecting the smooth filling of the liquid silicone rubber. Based on this, please refer to... Figure 4 , Figure 7 as well as Figure 8In one embodiment, a limiting wheel 407 is fixedly provided on the inner wall of the rectangular frame plate 402. The limiting wheel 407 has vertically distributed grooves 408. The material picking wheel 401 has a sliding groove 406 on the side away from the rotating shaft 403. A sliding rod 603 is fixedly provided on the side wall of the connecting rod 602. The end of the sliding rod 603 away from the connecting rod 602 extends from the sliding groove 406 to the outside of the material picking wheel 401 and acts on the circumferential side wall of the limiting wheel 407.

[0025] As the material-taking wheel 401 rotates, driving the two sets of pistons 601 and connecting rod 602 to rotate, the connecting rod 602 can drive the sliding rod 603 to slide against the circumferential side wall of the limiting wheel 407. At this time, the limiting wheel 407 limits the sliding rod 603, preventing the inclined connecting rod 602 and the two sets of pistons 601 from moving downwards due to gravity. That is, the liquid silicone rubber in the lower storage cavity 405 cannot be squeezed out. When one set of arc-shaped racks 503 disengages from the gear 504, keeping the material-taking wheel 401 stationary, the two sets of storage cavities 405 are vertically distributed. At this time, the sliding rod 603 slides to the position directly above the limiting wheel 407, the channel 408 is located below the sliding rod 603, and the two sets of pistons 601 and connecting rod 602 move downwards due to gravity. 602 drives the slide rod 603 to pass downwards along the inside of the channel 408. At the same time, the slide rod 603 slides down along the inside of the slide groove 406. When the piston 601 inside the upper storage cavity 405 moves down, it draws the liquid silicone rubber inside the storage cylinder 30 into the upper storage cavity 405 through the upper through hole 404. When the piston 601 inside the lower storage cavity 405 moves down, it presses the liquid silicone rubber in the lower storage cavity 405 into the container through the lower through hole 404, thereby realizing the precise filling operation of liquid silicone rubber. After the slide rod 603 passes through the inside of the channel 408, it moves to the bottom of the limiting wheel 407. After that, as the material picking wheel 401, the two sets of pistons 601 and the connecting rod 602 continue to rotate, the slide rod 603 continues to slide upwards against the circumferential side wall of the limiting wheel 407.

[0026] In one embodiment, the bottom of the feeding pipe 301 is configured with an arc-shaped structure that adapts to the circumferential sidewall of the picking wheel 401, so that the circumferential sidewall of the picking wheel 401 can fully fit with the bottom of the feeding pipe 301 during rotation, thereby preventing the liquid silicone rubber in the storage cylinder 30 from leaking between the feeding pipe 301 and the picking wheel 401.

[0027] In one embodiment, the upper edge of the holding tray 20 is provided with a plurality of slots for containers to be inserted. The plurality of slots are distributed in a ring at equal intervals. By inserting the container into the slot, the container can be positioned so that after the holding tray 20 is rotated at a certain angle, the container can be accurately transferred to the position below the material picking wheel 401, thereby improving the accuracy of liquid silicone rubber filling.

[0028] In this embodiment of the invention, when a filling operation is required for liquid silicone rubber, the drive component 50 can drive the holding tray 20 and the picking component 40 to rotate intermittently. At the same time, a robotic arm is used to place several containers for holding liquid silicone rubber in sequence at the upper edge of the holding tray 20. When the holding tray 20 rotates intermittently, it drives several containers to rotate intermittently in sync, thereby transferring several containers in sequence to the position below the picking component 40. When the picking component 40 and the holding tray 20 remain stationary, the pumping component 60 located inside the picking component 40 draws the liquid silicone rubber inside the storage cylinder 30 into the picking component 40 and presses the liquid silicone rubber inside the picking component 40 into the container below. In this way, a continuous automatic filling operation of liquid silicone rubber can be realized. Compared with the prior art, it can realize automatic continuous filling of liquid silicone rubber without much manual intervention, and has the advantages of good filling effect and high filling efficiency.

[0029] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
