Abstract
Description
Technical Field
[0001] This utility model belongs to the field of silicone production technology, specifically, it relates to a silicone production packaging equipment. Background Technology
[0002] Silica gel is a highly active adsorbent material, belonging to the amorphous category, and is mainly produced by aging and drying silica gel. It is soft, chemically stable, heat-resistant, and non-flammable. Due to its excellent adsorption properties, silica gel is widely used in food drying and preservation, medical products, electronic products, cosmetics and skincare, and industrial catalysis.
[0003] After silicone is produced and is in a liquid state, it is repackaged primarily for ease of storage, transportation, and use. Repackaging reduces storage space, prevents leakage from large containers during transport, and ensures product safety. At the same time, smaller packages allow for quick access on the production line, improving production efficiency.
[0004] Patent CN219730511 U discloses a high-efficiency silicone dispensing device, which improves the convenience of silicone dispensing and prevents spillage. However, in order to ensure continuous dispensing, the operator needs to constantly control the rotation of the dispensing tray and the opening and closing of the dispensing tube. The workload is large, and the operator will become more and more tired under the long-term repetitive operation, which is prone to errors and thus causes losses to the dispensing work. Utility Model Content
[0005] To address the technical problems of high workload and easy errors in silicone dispensing, this utility model provides a silicone dispensing equipment.
[0006] The objective of this utility model can be achieved through the following technical solutions:
[0007] A silicone packaging device includes a feed pipe connected to the upper center of a silicone tank.
[0008] The discharge pipe is connected to the lower center of the silicone box.
[0009] A circular conveyor belt is positioned below the silicone box.
[0010] A sealing plug is installed at the bottom of the silicone box corresponding to the position of the discharge pipe. A rotating rod is rotatably connected to the bottom of the sealing plug above the discharge pipe. An eccentric block is connected to the outside of the rotating rod. One end of the rotating rod passes through the discharge pipe and is connected to a gear on the outside of the discharge pipe.
[0011] The upper surface of the circular conveyor belt is connected to multiple evenly arranged placement plates. Above the placement plates, corresponding to the positions of the gears, are vertical plates. Above the vertical plates are racks, which intermittently mesh with the gears.
[0012] A base is located at the top center of the placement plate, and dispensing bottles are placed inside the base. A weighing sensor is installed inside the base.
[0013] Preferably, the bottom of the silicone box is shaped like an inverted platform.
[0014] Preferably, the sealing plug corresponds to the shape of the bottom of the silicone box and is in the shape of an inverted platform.
[0015] Preferably, a sliding plate is connected to the middle of the upper surface of the sealing plug, and symmetrically arranged limiting plates are provided on the outer side of the sliding plate. The sliding plate is slidably connected between the limiting plates, and a support rod is connected between the silicone line and the limiting plates.
[0016] Preferably, the length of the rack is equal to the circumference of the gear.
[0017] Preferably, the diameter of the upper opening of the dispensing bottle is greater than or equal to the diameter of the lower opening of the feeding pipe plus the diameter of the gear.
[0018] Preferably, the upper surface of the placement plate is symmetrically connected to the outside of the dispensing bottle, and the outside of the dispensing bottle is symmetrically connected to the auxiliary plates at the positions corresponding to the auxiliary plates. Multiple springs connect the auxiliary plates and the clamps.
[0019] A limit rod is connected to the clamp plate at the position corresponding to the spring. The limit rod is located inside the spring. A limit groove is opened on the auxiliary plate at the position corresponding to the limit rod. The limit rod is slidably connected in the limit groove.
[0020] Preferably, the upper part of the clamping plate has an arc-shaped surface.
[0021] The beneficial effects of this utility model are:
[0022] When dispensing liquid silicone, the circular conveyor belt is started, which drives the placement plate to move in a circular motion, thereby driving the rack and dispensing bottles to move in a circular motion. During the movement, the rack contacts and meshes with the gear. After the rack drives the gear to rotate 180°, the circular conveyor belt stops running. At this time, the liquid silicone flows out from the discharge pipe, and the dispensing bottles collect the liquid silicone. During the collection process, the weighing sensor weighs the liquid silicone. Once the liquid silicone collected in the dispensing bottles reaches the specified weight, the weighing sensor issues a running command to the circular conveyor belt, causing the conveyor belt to travel a certain distance (the distance between adjacent dispensing bottles). This allows for continuous dispensing of liquid silicone without errors, and can efficiently complete the dispensing work. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0038] Please see Figure 1 - Figure 5 As shown, a silicone production packaging device includes a silicone tank 1 for storing liquid silicone after production.
[0039] A feed pipe 11 is connected to the upper center of the silicone tank 1 for adding liquid silicone into the silicone tank 1.
[0040] A discharge pipe 12 is connected to the lower center of the silica gel tank 1 for collecting liquid silica gel;
[0041] The bottom of the silicone box 1 is shaped like an inverted platform. This design facilitates the flow of liquid silicone to the discharge pipe 12 and prevents liquid silicone from remaining in the silicone box 1.
[0042] A sealing plug 2 is provided inside the silicone box 1 at the lower position corresponding to the discharge pipe 12. The sealing plug 2 corresponds to the shape of the lower part of the silicone box 1 and is in the shape of an inverted platform. The sealing plug 2 is used to block the discharge pipe 12 to prevent liquid silicone from flowing out of the discharge pipe 12 when the liquid silicone has not been dispensed.
[0043] A sliding plate 22 is connected to the middle of the upper surface of the sealing plug 2. A symmetrically arranged limiting plate 23 is provided on the outer side of the sliding plate 22. The sliding plate 22 is slidably connected between the limiting plates 23. The sliding plate 22 and the limiting plate 23 cooperate to limit the position of the sealing plug 2, so that the sealing plug 2 can only move vertically, thereby enabling the sealing plug 2 to quickly and accurately block the discharge pipe 12.
[0044] A support rod 24 is connected between the silicone line and the limiting plate 23 to support the limiting plate 23.
[0045] A rotating rod 3 is rotatably connected above the discharge pipe 12 corresponding to the bottom of the sealing plug 2. An eccentric block 31 is connected to the outside of the rotating rod 3. The eccentric block 31 is used to squeeze the sealing plug 2, causing the sealing plug 2 to rise, so that the liquid silicone can flow from the silicone box 1 into the discharge pipe 12 for dispensing.
[0046] One end of the rotating rod 3 passes through the discharge pipe 12 and is connected to the gear 32 on the outside of the discharge pipe 12. The gear 32 is used to drive the rotating rod 3 to rotate.
[0047] A circular conveyor belt 13 is provided below the silicone box 1 to transport the dispensing bottles 52, so that the silicone box 1 can dispense liquid silicone into the dispensing bottles 52.
[0048] The upper surface of the annular conveyor belt 13 is connected to a plurality of evenly arranged placement plates 4. A vertical plate 41 is connected above the placement plate 4 at the position corresponding to the gear 32. A rack 42 is connected above the vertical plate 41. The rack 42 intermittently meshes with the gear 32 and is used to drive the gear 32 to rotate.
[0049] The length of rack 42 is equal to the circumference of gear 32. With this arrangement, after rack 42 moves to contact gear 32, gear 32, rotating rod 3 and eccentric block 31 can rotate one revolution. After the rotation of gear 32, rotating rod 3 and eccentric block 31, their positions do not change, so as not to affect the subsequent dispensing of liquid silicone and continuous operation can be carried out.
[0050] A base 5 is provided at the center of the upper part of the placement plate 4. A dispensing bottle 52 is placed inside the base 5. The base 5 is used to limit the position of the dispensing bottle 52 so that the dispensing bottle 52 can accurately correspond to the bottom of the discharge pipe 12.
[0051] The base 5 is equipped with a weighing sensor 51, which is used to weigh the liquid silica gel. After the liquid silica gel collected in the dispensing bottle 52 reaches the specified weight, the weighing sensor 51 will issue a running command to the circular conveyor belt 13, so that the circular conveyor belt 13 runs a certain distance (this running distance is the distance between adjacent dispensing bottles 52), thereby enabling continuous dispensing of liquid silica gel. It is worth noting that after the weighing sensor 51 issues a command, the dispensing bottle 52 containing liquid silica gel on the weighing sensor 51 needs to be removed. After removal, the gravity of the weighing sensor 51 is zeroed, and the next command can only be issued after the gravity is zeroed.
[0052] The diameter of the upper opening of the dispensing bottle 52 is greater than or equal to the diameter of the lower opening of the feeding pipe plus the diameter of the gear 32. This setting ensures that when dispensing liquid silicone, the liquid silicone flowing out of the discharge pipe 12 can completely enter the dispensing bottle 52 and will not flow out of the dispensing bottle 52, thus avoiding waste.
[0053] In practical use, when dispensing liquid silicone, the annular conveyor belt 13 is activated, causing the placement plate 4 to move in a circular motion. This, in turn, causes the rack 42 and the dispensing bottle 52 to move in a circular motion. During this motion, the rack 42 contacts and meshes with the gear 32.
[0054] When the rack 42 drives the gear 32 to rotate 90°, the gear 32 drives the rotating rod 3 and the eccentric block 31 to rotate, so that the eccentric block 31 just contacts the sealing plug 2, and under the operation of the placement plate 4, the lower opening of the feeding tube corresponds to the upper opening of the dispensing bottle 52.
[0055] When the rack 42 drives the gear 32 to rotate 90°-270°, the eccentric block 31 rotates and lifts the sealing plug 2, so that the upper end of the discharge pipe 12 is no longer blocked. Liquid silicone can enter the discharge pipe 12 from the silicone box 1 and fall from the discharge pipe 12 into the dispensing bottle 52 to dispense the liquid silicone. During the process of the rack 42 driving the gear 32 to rotate 90°-270°, the placement plate 4 will drive the dispensing bottle 52 to continue to move a certain distance. During this distance of movement of the dispensing bottle 52, the lower opening of the discharge pipe always corresponds to the upper opening of the dispensing bottle 52, so that the liquid silicone will not flow to the outside of the dispensing bottle 52.
[0056] When the rack 42 drives the gear 32 to rotate 270°-360°, the eccentric block 31 rotates to the initial position to prepare for the next assembly.
[0057] After the rack 42 drives the gear 32 to rotate 180°, the annular conveyor belt 13 will stop running. At this time, the liquid rubber is flowing out of the discharge pipe 12, and the dispensing bottle 52 collects the liquid rubber. During the collection process, the weighing sensor 51 weighs the liquid silicone. After the liquid silicone collected in the dispensing bottle 52 reaches the specified weight, the weighing sensor 51 will issue a running command to the annular conveyor belt 13, so that the annular conveyor belt 13 runs a certain distance (this running distance is the distance between adjacent dispensing bottles 52), so that the liquid silicone can be continuously dispensed without error and the dispensing work can be completed efficiently.
[0058] The upper surface of the placement plate 4 is connected to the outside of the dispensing bottle 52 by symmetrically arranged auxiliary plates 6. The outside of the dispensing bottle 52 is provided with symmetrically arranged clamping plates 62 corresponding to the auxiliary plates 6, which are used to clamp and fix the dispensing bottle 52 so that the dispensing bottle 52 can be stable.
[0059] An arc-shaped surface 63 is provided above the clamping plate 62, so that the dispensing bottle 52 can be placed more smoothly between the two clamping plates 62;
[0060] Multiple springs 61 are connected between the auxiliary plate 6 and the clamping plate 62 for resetting the clamping plate 62.
[0061] A limiting rod 64 is connected to the clamping plate 62 at the position corresponding to the spring 61. The limiting rod 64 is located inside the spring 61. A limiting groove 65 is opened on the auxiliary plate 6 at the position corresponding to the limiting rod 64. The limiting rod 64 is slidably connected in the limiting groove 65. The limiting rod 64 and the limiting groove 65 cooperate to limit the position of the clamping plate 62 and prevent the clamping plate 62 from deflecting.
[0062] In practical use, when removing the dispensing bottle 52 containing liquid silica gel, a new dispensing bottle 52 needs to be placed. When placing it, the dispensing bottle 52 is aligned between the two clamps 62 and inserted. With the cooperation of the arc surface 63, the dispensing bottle 52 can be inserted more smoothly. During the insertion process, the clamps 62 will be squeezed outward, which will cause the spring 61 to contract. After the spring 61 contracts, it will store the restoring force. The restoring force acts on the dispensing bottle 52, which can make the dispensing bottle 52 more stable.
