Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of modifier production equipment, and in particular to a material retaining structure for a two-roll mill and a two-roll mill for modifier testing. Background Technology
[0002] The full name of an open mixing mill is an open-type rubber mixing mill. It is one of the basic pieces of equipment in the rubber industry. Its structure usually includes a base, frame, motor, rollers installed in parallel between the frame, and a receiving tray set below the rollers. The drive device drives the rollers to move inward at different speeds. The rubber compound is added from the middle of the rollers and is drawn into the gap between the rollers as the rollers rotate. It is mixed by strong shearing and extrusion. The sheet-like rubber compound that falls from the middle of the rollers and the overflow material that spills from the sides of the rollers are caught by the receiving tray and collected together and then added back from the middle of the rollers. Through repeated shearing and extrusion, the purpose of plasticizing or mixing is achieved.
[0003] When the rollers extrude the rubber material, some of the material slides along the rollers and easily falls to both ends of the roller's long axis. The rollers cannot extrude the material that has fallen to both ends, so workers need to repeatedly place the material between the two rollers for extrusion, which increases the workload of the workers and reduces production efficiency.
[0004] In view of this, the inventor specifically designed a material retaining structure for a two-roll mill and a two-roll mill for testing modifiers, which led to this invention. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model. Example 1
[0027] Please see Figures 1 to 6 This is a material blocking structure for an open mill, as described in Embodiment 1 of this utility model. It is installed on the open mill and includes a support base 10, an adjusting device 20, a first locking member 30, and a material blocking device 40. The support base 10 is installed on the open mill; the adjusting device 20 is installed on the support base 10 and is tunably connected to it; the first locking member 30 is installed on the support base 10 and is used to restrict the movement of the adjusting device 20 on the support base 10; the material blocking device 40 is installed on the adjusting device 20; the material blocking device 40 includes a baffle 41 installed on the adjusting device 20 and pulleys 42 installed on the baffle 41. At least two pulleys 42 are provided and located at the lower edge of the baffle 41. The tunable connection can be understood as: the adjusting device 20 is movably connected to the support base 10 and is limited by bolts to prevent the adjusting device 20 from moving on its own. The present invention uses a material blocking device 40 to block the rubber material, which can prevent the rubber material from slipping to both ends and improve production efficiency. At the same time, a pulley 42 is also provided to prevent the open mill roll 70 from squeezing the baffle 41 and avoid affecting its use.
[0028] Please refer to details. Figure 4 The outermost edge of pulley 42 extends beyond the bottom of baffle 41 so that pulley 42 can abut against the outer surface of open mill roll 70, while preventing the lower edge of the baffle from contacting open mill roll 70.
[0029] Please refer to details. Figure 2-3The adjusting device 20 includes an adjusting rod 21 mounted on and slidably connected to a support base 10, and an adjusting plate 22 located at the end of the adjusting rod 21. The support base 10 has holes 11 through which the adjusting rod 21 passes. After passing through the support base 10, the adjusting rod 21 is fixedly connected to the adjusting plate 22. At least one adjusting rod 21 is provided; this invention provides two, corresponding to two first locking members 30. The first locking members 30 are threadedly connected to the support base 10 for a stable connection. That is, two adjusting rods 21 are provided side-by-side, and the adjusting plate 22 is located at the ends of the two adjusting rods 21. The adjusting rod 21 can be fixed to the adjusting plate 22 by screwing or welding. A limiting step 221 is also provided at the end of the adjusting rod 21 furthest from the adjusting plate 22. The first locking member 30 can be a bolt, threadedly connected to the support base 10. When the bolt abuts against the outer wall of the adjusting rod 21, the adjusting rod 21 is restricted from moving. The first locking element 30 preferably uses a quick-release bolt, such as a wing bolt. This utility model uses two adjusting rods 21, which not only stably support the material blocking device 40, but also strengthen the restriction on the position of the adjusting device 20 by setting two first locking elements 30, thus preventing displacement after use.
[0030] Please refer to the details. Figure 4 , 6 The baffle 41 has inwardly recessed arc-shaped grooves 411 on both sides below it. The arc-shaped grooves 411 are mainly designed to fit the shape of the open mill roll 70, so that the bottom of the baffle 41 can be as close as possible to the outer surface of the open mill roll 70.
[0031] Please refer to the details. Figure 3 , 4 5. The material-stopping device 40 also includes a limiting component 43 for restricting the pulleys 42 to the baffle 41. The limiting component 43 includes a fixed plate 431 and a rotating shaft 432 with one end disposed on the baffle 41 and the other end disposed on the fixed plate 431. The pulleys 42 are sleeved on the rotating shaft 432 and are located between the fixed plate 431 and the baffle 41. The fixed plate 431 is bolted to the baffle 41, and a groove similar to the arc-shaped groove 411 is also provided below the fixed plate 431. This utility model provides six pulleys 42, with three pulleys provided in any one of the arc-shaped grooves 411. The pulleys 42 can adopt a bearing-like structure.
[0032] Please refer to the details. Figure 3 , 4 An elongated hole 221 is provided on the adjusting plate 22. The second locking member 50 passes through the elongated hole 221 and is connected to the baffle 41. Specifically, the elongated hole 221 is vertically arranged to adjust the vertical height of the baffle 41. The second locking member 50 is a bolt that passes through the elongated hole 221 and is threadedly connected to the baffle 41. Therefore, the baffle 41 is provided with an internal threaded hole for cooperating with the second locking member 50.
[0033] Please refer to details. Figure 5 A clearance groove 412 is provided on the baffle 41 along the arc groove 411. The pulley 42 is placed in the clearance groove 412 and partially protrudes from the clearance groove 412 and is located in the arc groove 411. The fixing plate 431 is provided with a protrusion facing the clearance groove 412. The space formed between the protrusion and the clearance groove 412 is used to install the pulley 42. This arrangement can reduce the overall thickness of the baffle 41 device, reduce the weight, and facilitate quick adjustment of the position of the baffle 41 device. Example 2
