Description

Technical Field

[0001] This utility model relates to the field of silicone processing equipment design, and in particular to a driven roller adjustment mechanism for a silicone open mill. Background Technology

[0002] Silicone is a common material that is non-toxic, odorless, and insoluble in water. Due to its strong chemical stability, silicone is widely used in various fields, such as industry, medical, food, and furniture.

[0003] To facilitate the shaping of silicone into various products, it is necessary to use a silicone open mill for plasticizing. Common silicone open mills typically include a drive roller and a driven roller that rotate relative to each other. By repeatedly passing the silicone material between these rotating rollers, the material undergoes shearing and compression, effectively improving its plasticity and achieving plasticization.

[0004] In actual processing, it was found that the distance between the driven roller and the driving roller of the commonly used silicone open mill is mostly constant. However, the silicone material passing through it requires different distances due to different thicknesses and other conditions. The open mill often cannot effectively meet these requirements, resulting in insufficient flexibility. In addition, the silicone material tends to stick to the driven roller after being compressed, forming residues that are not conducive to the use of the driven roller. This means that common silicone open mills need to be stopped for cleaning the driven roller after long-term use, which is time-consuming and labor-intensive. Utility Model Content

[0005] The purpose of this invention is to provide a driven roller adjustment mechanism for a silicone open mill, which can solve one or more of the above-mentioned problems.

[0006] According to one aspect of the present invention, a driven roller adjustment mechanism for a silicone open mill is provided, comprising a driven roller, an adjustment mechanism, a scraper mechanism, and a support.

[0007] The adjustment mechanism comprises two components, each including a cylinder mechanism, a rocker arm, a connecting shaft, and a linear motor. One end of the rocker arm is hinged to a bracket, and the other end is connected to the connecting shaft. The cylinder mechanism is mounted on the bracket and connected to the rocker arm. A guide rail is provided on the rocker arm, and the linear motor is connected to the guide rail.

[0008] The two ends of the driven roller are respectively connected to the connecting shafts of the two adjustment mechanisms, and the two ends of the scraper mechanism are respectively connected to the linear motors of the two adjustment mechanisms.

[0009] The beneficial effects of this utility model are as follows: In this utility model, the driven roller can rotate on the connecting shaft, and the cylinder mechanism can drive the swing arm to swing, thereby adjusting the position of the driven roller and changing the distance between the driven roller and the driving roller to adapt to different plasticizing requirements of silicone. It is highly flexible and practical. In addition, a scraper mechanism and a linear motor that can drive the scraper mechanism to move are also provided. It is convenient to drive the scraper mechanism close to the driven roller to scrape off the silicone material attached to the driven roller when it is necessary. This operation does not require special machine stopping, saving time and effort.

[0010] In some embodiments, the scraper mechanism includes a scraper, a connecting column, and clamping blocks, wherein there are multiple clamping blocks, the scraper is connected to multiple clamping blocks, and the clamping blocks are sleeved on the connecting column.

[0011] In some embodiments, the clamping block includes an upper clamping block and a lower clamping block, the upper clamping block being connected to the lower clamping block and forming a through hole through which the connecting post can pass. Thus, the upper and lower clamping blocks can be easily separated and reassembled when needed, facilitating adjustment of the clamping position and angle of the clamping block on the connecting post, thereby adjusting the setting angle and position of the scraper to match different needs.

[0012] In some embodiments, the present invention further includes a limiting mechanism mounted on a bracket, which is configured to limit the swing limit position of the swing arm. The limiting mechanism prevents excessive swinging of the swing arm from causing collisions between the driven roller and the driving roller, thus improving the operational safety of the present invention.

[0013] In some embodiments, the limiting mechanism includes a limit switch and a switch base, wherein the switch base is mounted on a bracket and the limit switch is mounted on the switch base.

[0014] In some embodiments, the cylinder mechanism includes a cylinder body, a piston rod, a first hinge block, and a second hinge block. One end of the piston rod is mounted in the cylinder body, and the other end is connected to the first hinge block. The cylinder body and the second hinge block are connected, and the second hinge block is hinged to a bracket. The first hinge block facilitates the hinge connection between the piston rod and the rocker arm, while the second hinge block facilitates the hinge mounting of the cylinder body to the bracket.

[0015] In some embodiments, the first hinge block has a groove, and the rocker arm has a protrusion that extends into the groove and is hinged to the first hinge block. The groove and protrusion facilitate the hinge of the rocker arm to the first hinge block, and the groove also acts as a limiter to restrict the range of motion of the protrusion.

[0016] In some embodiments, the driven roller includes a roller body and a bearing, the bearing being fitted into the roller body and sleeved on a connecting shaft. The bearing facilitates rotation of the roller body on the connecting shaft.

[0017] In some embodiments, the linear motor includes a motor body, a gear, and a housing. The motor body is mounted on the housing and connected to the gear. The rocker arm has a rack, and the gear meshes with the rack. The housing is slidably connected to a guide rail. As the motor body operates, the gear rotates on the rack, thereby driving the linear motor to move along the guide rail. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] refer to Figures 1-4 The present invention relates to a driven roller adjustment mechanism for a silicone open mill, comprising a driven roller 1, an adjustment mechanism 2, a scraper mechanism 3, and a support 4.

[0026] The adjustment mechanism 2 is preferably two, and each adjustment mechanism 2 includes a cylinder mechanism 21, a rocker arm 22, a connecting shaft 23 and a linear motor 24.

[0027] The cylinder mechanism 21 includes a cylinder body 211, a piston rod 212, a first hinge block 213, and a second hinge block 214. One end of the piston rod 212 is linearly movable inside the cylinder body 211 via a piston, and the other end of the piston rod 212 is fixedly connected to the first hinge block 213 by screws. The bottom of the cylinder body 211 is fixedly connected to the second hinge block 214 by screws.

[0028] The second hinge block 214 is hinged to the bracket 4 by a pin, so that the cylinder 211 can rotate on the bracket 4.

[0029] The first hinge block 213 has a groove 2131 in the middle, and the rocker arm 22 has a protrusion 221 on one side. The protrusion 221 extends into the groove 2131, and the protrusion 221 is hinged to the first hinge block 213 by a pin, so that the protrusion 221 can rotate relative to the first hinge block 213.

[0030] One end of the swing rod 22 is hinged to the bracket 4 by a pin. The movement of the piston rod 212 can drive the swing rod 22 to swing around the pin that connects it to the bracket 4. The other end of the swing rod 22 is fixedly connected to a connecting shaft 23, which is set perpendicular to the swing rod 22.

[0031] The driven roller 1 includes a roller body 11 and bearings 12. Preferably, there are two bearings 12. The two bearings 12 are fixedly embedded in the center of both ends of the roller body 11, and the two bearings 12 are fixedly sleeved on the connecting shafts 23 of the two adjusting mechanisms 2. So that the two ends of the driven roller 1 are connected to the connecting shafts 23 of the two adjusting mechanisms 2, the driven roller 1 can move with the movement of the connecting shafts 23. At the same time, the driven roller 1 can also rotate relative to the connecting shafts 23.

[0032] A guide rail 222 is provided on the other side of the swing arm 22. The linear motor 24 is connected to the guide rail 222. Under the operation of the linear motor 24, the linear motor 24 can move linearly along the guide rail 222.

[0033] Preferably, the linear motor 24 can be a commercially available linear motor that can move linearly directly on the guide rail 222. In this embodiment, the linear motor 24 can include a motor body, a gear 241, and a housing. A rack 242 is also provided on the rocker arm 22. The motor body is embedded in the housing, and the output shaft of the motor body extends from the housing and is connected to the gear 241, so that the motor body can drive the gear 241 to rotate. The housing is slidably fitted on the guide rail 222, and the gear 241 and the rack 242 mesh, so that the motor body can drive the gear 241 to rotate, so that the gear 241 moves along the rack 242, thereby causing the housing to slide along the guide rail 222 to realize the linear movement of the linear motor 24.

[0034] The scraper mechanism 3 includes a scraper 31, a connecting column 32, and a clamping block 33. There can be multiple clamping blocks 33. In this embodiment, two clamping blocks 33 are preferred. The scraper 31 and the two clamping blocks 33 are fixedly connected by screws, and the two clamping blocks 33 are fixedly sleeved on the connecting column 32.

[0035] Preferably, each clamping block 33 includes an upper clamping block 331 and a lower clamping block 332, which are fixedly connected by screws. The upper clamping block 331 and the lower clamping block 332 can form a through hole through which the connecting post 32 can pass. When needed, the user can disassemble the clamping block 33 to separate the upper clamping block 331 and the lower clamping block 332, thereby allowing the clamping block 33 to detach from the connecting post 32. At this time, the setting angle and setting position of the upper clamping block 331 and the lower clamping block 332 on the connecting post 32 can be adjusted. After that, the upper clamping block 331 and the lower clamping block 332 can be reconnected to effectively adjust the setting of the clamping block 33 on the connecting post 32, thereby effectively adjusting the setting angle and setting position of the scraper 31 connected to the clamping block 33 on the connecting post 32.

[0036] The two ends of the connecting column 32 in the scraper mechanism 3 are respectively connected to the linear motors 24 of the two adjustment mechanisms 2 through connecting blocks, so that the movement of the linear motors 24 can drive the connecting column 32 to move together.

[0037] The driven roller adjustment mechanism of this silicone open mill also includes a limit mechanism 5. The limit mechanism 5 includes a limit switch 51 and a switch base 52. The limit switch 51 is fixedly mounted on the switch base 52 by screws, and the switch base 52 is fixedly mounted on the bracket 4 by screws. The setting position of the limit switch 51 can be set according to the swing limit position required by the swing rod 22, so that when the swing rod 22 swings to the required limit position, it will abut against the limit switch 51.

[0038] This silicone open mill driven roller adjustment mechanism can be used in silicone open mills. The drive roller of the silicone open mill can also be set on the support 4. After the setting, there is a certain distance between the drive roller and the driven roller 1. When the drive roller rotates, the silicone material can pass through the distance between the drive roller and the driven roller 1, and the driven roller 1 can also rotate accordingly. The silicone material can be plasticized by the shear force between them. The user can adjust the position of the driven roller 1 through the adjustment mechanism 2, thereby adjusting the distance between the driven roller 1 and the drive roller to match the different needs of the silicone material being plasticized.

[0039] Specifically, the cylinder mechanism 21 can be activated to move the piston rod 212. The movement of the piston rod 212 can drive the swing rod 22 to swing, so that the driven roller 1 connected to the swing rod 22 can follow the movement, thereby allowing the driven roller 1 to move closer to or further away from the driving roller, thus realizing the adjustment of the distance between the driven roller 1 and the driving roller.

[0040] In addition, after prolonged plasticizing of silicone material, when a large amount of silicone material remains on the driven roller 1, the linear motor 24 can be activated. The linear motor 24 can move along the guide rail 222, and the connecting column 32 connected to the linear motor 24 moves. The scraper 31 connected to the connecting column 32 via the clamping block 33 moves accordingly, causing the scraper 31 to gradually approach the surface of the driven roller 1. At this time, when the driven roller 1 rotates, the silicone material adhering to the surface of the driven roller 1 can be gradually scraped off by the scraper 31, thus cleaning the driven roller 1. After the silicone material is scraped off, the linear motor 24 can move along the guide rail 222 to drive the scraper 31 away from the driven roller 1, avoiding contact between the scraper 31 and the driven roller 1 and thus preventing obstruction of the operation of the driven roller 1.

[0041] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
