[0005] To address the shortcomings of existing technologies, this utility model provides a silicone rubber product cleaning device, which solves the problem that drying silicone rubber products consumes manpower and time, affecting production efficiency.

[0006] According to an embodiment of this utility model, a silicone rubber product cleaning device includes a frame and a cleaning tank mounted on the frame. The frame also includes a liftable cover and a first drive assembly pulsatingly connected to the cover. The first drive assembly drives the cover to move closer to or further away from the opening of the cleaning tank. The cover includes a rotatable main shaft and a second drive assembly pulsatingly connected to the main shaft. The main shaft is vertically mounted on the cover. The end of the main shaft has a sleeve, and the axial direction of the sleeve is perpendicular to the axial direction of the main shaft. A rotatable rotating frame is provided inside the sleeve. A cleaning cage and a spherical head are fixedly connected to the rotating frame. The cover also includes a liftable movable ring and a third drive assembly pulsatingly connected to the movable ring. The inner circumferential wall of the movable ring has an annular groove, and the spherical head extends into the annular groove and abuts against the movable ring. A fan bracket is provided on the cleaning tank, and a fan is provided on the fan bracket. The air outlet direction of the fan is towards the opening of the cleaning tank.

[0007] Furthermore, the first drive assembly includes a first motor and a lead screw disposed at the output end of the first motor. The lead screw is rotatably disposed on the frame and the axial direction of the lead screw is consistent with the vertical direction. The cover plate is provided with a threaded hole that mates with the lead screw.

[0008] Furthermore, the frame is also provided with a guide rod, which is arranged parallel to the lead screw, and the cover plate is provided with a guide hole that cooperates with the guide rod.

[0009] Furthermore, the second drive assembly includes a second motor and a rotating rod disposed at the output end of the second motor. The rotating rod is rotatably connected to the cover plate and fixedly connected to the main shaft.

[0010] Furthermore, the rotating frame has a connecting seat with a through hole, the cleaning cage has a connecting screw that mates with the through hole, the connecting screw has a connecting nut that mates with the connecting screw, and the connecting nut abuts against the side of the connecting seat away from the cleaning cage.

[0011] Furthermore, the cleaning cage has a material inlet, and the cleaning cage is also provided with a rotatable cage door that closes the material inlet.

[0012] Furthermore, the cleaning cage is provided with a locking seat, the locking seat is provided with a rotatable locking screw and a locking nut that cooperates with the locking screw, the cage door is provided with a locking plate, the locking plate has a slot for the locking screw to pass through, and the locking nut abuts against the side of the locking plate away from the locking seat and presses the locking plate onto the locking seat.

Detailed Implementation

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 5 As shown in the figure, this utility model embodiment proposes a silicone rubber product cleaning device for cleaning silicone rubber products to remove dust or dirt adhering to the surface of silicone rubber products during the production process, and drying the cleaned silicone rubber products.

[0025] Please refer to Figure 1 , Figure 2 and Figure 3The silicone rubber product cleaning device includes a frame 1 and a cleaning tank 2 mounted on the frame 1. The frame 1 also has a liftable cover 3 and a first drive assembly pulsatingly connected to the cover 3. The first drive assembly drives the cover 3 to move closer to or further away from the opening of the cleaning tank 2. When the cover 3 moves to a position covering the opening of the cleaning tank 2, it closes the opening. The cover 3 has a rotatable main shaft 4 and a second drive assembly pulsatingly connected to the main shaft 4. The main shaft 4 is vertically mounted on the cover 3. A sleeve 41 is provided at the end of the main shaft 4, and the axial direction of the sleeve 41 is perpendicular to the axial direction of the main shaft 4. A rotatable rotating frame 5 is provided inside the sleeve 41. A cleaning cage 6 and a spherical head 51 are fixedly connected to the rotating frame 5. The cleaning cage 6 is used to place the silicone rubber product to be cleaned. When the main shaft 4 rotates under the drive of the second drive assembly, it drives the cleaning cage 6 to rotate axially around the main shaft 4. The cover plate 3 is also provided with a liftable movable ring 7 and a third drive assembly connected to the movable ring 7. The inner circumferential wall of the movable ring 7 has an annular groove 71, and the spherical head 51 extends into the annular groove 71 and abuts against the movable ring 7. When the movable ring 7 rises and falls under the drive of the third drive assembly, it drives the spherical head 51 to move and causes the rotating frame 5 to rotate within the sleeve 41, thereby causing the cleaning cage 6 to rotate axially around the sleeve 41. The cleaning tank 2 is provided with a fan bracket 8, and the fan bracket 8 is provided with a fan 81. The airflow of the fan 81 faces the opening of the cleaning tank 2, and the airflow blown by the fan 81 can dry the silicone rubber products inside the cleaning cage 6.

[0026] Specifically, the operation steps for cleaning silicone rubber products using the silicone rubber product cleaning device provided in this embodiment are as follows: First, the silicone rubber product to be cleaned is placed in the cleaning cage 6. Then, the first driving component drives the cover plate 3 to descend to cover the opening of the cleaning tank 2. At this time, the cleaning cage 6 is placed in the cleaning tank 2. Cleaning liquid is injected into the cleaning tank 2, and the second driving component drives the main shaft 4 to rotate, thereby rotating the cleaning cage 6 inside the cleaning tank 2. This cleans the silicone rubber product in the cleaning cage 6. After cleaning, the cleaning liquid in the cleaning tank 2 is discharged, and the second driving component drives the cleaning cage 6 to rotate and spin-dry the silicone rubber product. During the spin-drying process, the third driving component drives the movable ring 7 to move vertically. The lifting mechanism, through the engagement of the spherical head 51 and the annular groove 71, drives the rotating frame 5 to rotate within the sleeve 41. The rotation of the rotating frame 5 tilts the cleaning cage 6, causing the silicone rubber products to roll within it, preventing accumulation and incomplete drying. After drying, the first drive assembly drives the cover plate 3 to rise, removing the cleaning cage 6 from the cleaning tub 2. Then, the fan 81 blows airflow into the cleaning cage 6 to dry the silicone rubber products. During this drying process, the second and third drive assemblies simultaneously rotate and oscillate the cleaning cage 6, ensuring full contact between the silicone rubber products and the airflow, guaranteeing complete drying. The silicone rubber product cleaning device provided in this embodiment can automatically clean, spin-dry, and blow-dry silicone rubber products, improving drying efficiency, saving manpower, and increasing production efficiency.

[0027] like Figure 2 and Figure 4 As shown, the first drive assembly includes a first motor 11 and a lead screw 12 disposed at the output end of the first motor 11. The lead screw 12 is rotatably mounted on the frame 1, and the axial direction of the lead screw 12 is aligned with the vertical direction. The cover plate 3 is provided with a threaded hole 31 that mates with the lead screw 12. When the lead screw 12 rotates under the drive of the first motor 11, the cover plate 3 is driven to move along the axial direction of the lead screw 12 through the engagement of the threaded hole 31 with the lead screw 12, thereby adjusting the position of the cover plate 3 in the vertical direction. This allows the cover plate 3 to be moved to a position covering the opening of the cleaning tub 2 or to a position away from the cleaning tub 2.

[0028] In this embodiment, the frame 1 is further provided with a guide rod 13, which is arranged parallel to the lead screw 12, and the cover plate 3 is provided with a guide hole 32 that cooperates with the guide rod 13. The guide rod 13 on the frame 1 is used to cooperate with the guide hole 32 on the cover plate 3 to limit the movement direction of the guide rod 13, prevent the cover plate 3 from deviating from the preset direction or tilting when it moves vertically, and improve the stability of the cover plate 3 when it moves.

[0029] like Figure 3 As shown, the second drive assembly includes a second motor 33 and a rotating rod 34 disposed at the output end of the second motor 33. The rotating rod 34 is rotatably connected to the cover plate 3 and fixedly connected to the main shaft 4. The transmission connection between the main shaft 4 and the second motor 33 is achieved by setting the rotating rod 34, which is fixedly connected to the main shaft 4, at the output end of the second motor 33. When the second motor 33 drives the rotating rod 34 to rotate, it drives the main shaft 4 to rotate, and simultaneously drives the cleaning cage 6 to rotate, thereby cleaning and drying the silicone rubber products inside the cleaning cage 6.

[0030] Please refer to the following: Figure 3 and Figure 5 The rotating frame 5 has a connecting seat 52 with a through hole. The cleaning cage 6 has a connecting screw 61 that mates with the through hole. The connecting screw 61 has a connecting nut 62 that mates with the connecting screw 61, and the connecting nut 62 abuts against the side of the connecting seat 52 away from the cleaning cage 6. When installing the cleaning cage 6 onto the rotating frame 5, first pass the connecting screw 61 through the through hole, then use the connecting nut 62 to mate with the connecting screw 61 and tighten the connecting nut 62 so that the connecting nut 62 abuts against the connecting seat 52. This fixes the cleaning cage 6 onto the rotating frame 5 and ensures a secure connection between the cleaning cage 6 and the rotating frame 5.

[0031] Please refer to Figure 5 The cleaning cage 6 has a material inlet 63 and a rotatable cage door 64 that closes the material inlet 63. The material inlet 63 is used to place or remove silicone rubber products from the cleaning cage 6. The material inlet 63 can be opened or closed by rotating the cage door 64. When the cage door 64 closes the material inlet 63, the silicone rubber products inside the cleaning cage 6 remain inside the cleaning cage 6 during the cleaning process, preventing the silicone rubber from being thrown out of the cleaning cage 6 when it rotates.

[0032] In detail, the cleaning cage 6 is provided with a locking seat 65, the locking seat 65 is provided with a rotatable locking screw 66 and a locking nut 67 that cooperates with the locking screw 66, the cage door 64 is provided with a locking plate 68, the locking plate 68 has a slot 69 for the locking screw 66 to pass through, and the locking nut 67 abuts against the side of the locking plate 68 away from the locking seat 65 and presses the locking plate 68 onto the locking seat 65. After the cage door 64 is rotated to close the feed inlet 63, the locking plate 68 approaches the locking seat 65. At this time, the locking screw 66 is rotated to enter the slot 69 on the locking plate 68, and then the locking nut 67 is rotated to abut against the locking plate 68, so that the locking plate 68 is pressed against the locking seat 65, thus keeping the cage door 64 closed and preventing the cage door 64 from rotating unexpectedly during the cleaning process.

[0033] like Figure 2 and Figure 3 As shown, the third drive assembly includes a cylinder 35 and a piston rod 36 disposed at the output end of the cylinder 35. One end of the piston rod is fixedly connected to the movable ring 7. The piston rod 36 is extended or retracted by the cylinder 35, causing the movable ring 7 to move vertically under the influence of the piston rod 36. This allows the rotating frame 5 to rotate within the sleeve 41 by controlling the cylinder 35, thus adjusting the tilt angle of the cleaning cage 6. The tilt angle of the cleaning cage 6 can be adjusted so that the end of the cleaning cage 6 with the material inlet 63 is lower than the height of the inlet 63, causing the silicone rubber products inside the cleaning cage 6 to gather towards the material inlet 63 under gravity, facilitating the removal of the cleaned silicone rubber products.

[0034] In this embodiment, two cylinders 35 are spaced apart on the cover plate 3, and the piston rods 36 on the two cylinders 35 are fixedly connected to the opposite sides of the movable ring 7. By setting the two cylinders 35 to drive the piston ring to move vertically at the same time, the piston ring moves smoothly, which helps to improve the stability of the silicone rubber product cleaning device during operation.

[0035] like Figure 1 As shown, two fans 81 are spaced apart on the fan bracket 8, and the fans 81 are arranged in a row on the fan bracket 8. The two fans 81 spaced apart on the fan bracket 8 blow airflow onto the silicone rubber products in the cleaning cage 6, which helps to accelerate the drying of the silicone rubber products in the cleaning cage 6 and improves the working efficiency of the silicone rubber product cleaning device.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
