Abstract
Description
Technical Field
[0001] The present application relates to the technical field of open mixing mill manufacturing, and in particular to a double-roll open mixing mill. Background Art
[0002] In the prior art, double-roll mills are widely used in many fields (for example, in the production of rubber or plastic products) due to their advantages such as high efficiency, convenience and good operating stability. However, due to the poor structural design of the existing double-roll mills, when a safety accident occurs, especially when the operator's hands are injured and lose mobility or their hands are stuck in the equipment, it is difficult for the operator to trigger the emergency stop switch in a timely and convenient manner, which can easily cause more serious secondary injuries to the operator. Utility Model Content
[0003] The purpose of the present application is to provide a twin-roll mill that can shut down the equipment promptly and conveniently after an accident occurs, thereby reducing the probability of secondary accidents and better protecting the personal safety of operators.

[0005] The embodiment of the present application provides a double-roll mill, comprising a base, two working rolls, an auxiliary trigger unit and an auxiliary emergency stop switch. The base has two mounting parts arranged opposite to each other; the two working rolls are mounted side by side between the two mounting parts, and the two ends of each working roll are respectively rotatably arranged on the two mounting parts; the auxiliary trigger unit comprises a trigger rod, and the two ends of the trigger rod are respectively slidably arranged on the two mounting parts; the auxiliary emergency stop switch is electrically connected to the control system of the double-roll mill, and the auxiliary emergency stop switch is located on the sliding path of the trigger rod and can be triggered by the trigger rod.
[0006] In the above technical scheme, the double-roll mill is additionally provided with an auxiliary trigger unit and an auxiliary emergency stop switch, wherein the two ends of the trigger rod in the auxiliary trigger unit are respectively slidably arranged on two mounting parts (i.e., the trigger rod spans the entire working roll), and the auxiliary emergency stop switch is located on the sliding path of the trigger rod and can be triggered by the trigger rod. Through the mutual cooperation of the trigger rod and the auxiliary emergency stop switch, when an accident occurs and the equipment needs to be shut down, the operator can drive the trigger rod through many positions of the body (such as hands, head, and torso, etc.) by virtue of the large space occupied by the trigger rod and the sliding characteristics, thereby shutting down the equipment. Compared with the mill of traditional structure (usually the emergency stop switch can only be triggered by hand to shut down the equipment), after an accident occurs, the specific form of the double-roll mill provided in the present application can shut down the equipment more promptly and conveniently, thereby reducing the probability of secondary accidents, so as to better protect the personal safety of the operator.
[0007] In some optional implementation schemes, two auxiliary emergency stop switches are provided, and the two auxiliary emergency stop switches are respectively mounted on two mounting members and are respectively located on two sliding paths at two ends of the trigger rod.

[0009] In some optional embodiments, the two auxiliary emergency stop switches are located on the same side of the two sliding paths.
[0010] In the above technical solution, the two auxiliary emergency stop switches are arranged on the same side of the two sliding paths so that the two auxiliary emergency stop switches can be triggered simultaneously each time, which has the advantage of a higher safety factor. At the same time, this setting form also has the advantage of strong controllability.
[0011] In some optional embodiments, each mounting member includes a mounting plate, a guide rod and two mounting rods, the two mounting rods are spaced apart and vertically protruded on the top of the mounting plate, the two ends of the guide rod are respectively fixed to the two mounting rods, and the guide rod is arranged along the extension direction of the sliding path, and the auxiliary emergency stop switch is located at the end of the sliding path; the trigger rod includes a rod body and trigger plates located at both ends of the rod body, and each trigger plate is slidably set on the corresponding guide rod along the direction of the sliding path.
[0012] In the above technical solution, the mounting part is arranged in the form of a mounting plate, a guide rod and two mounting rods cooperating with each other, the trigger rod is arranged in the form of a rod body and a trigger plate cooperating with each other, and the trigger plate is slidably arranged on the corresponding guide rod, so that the double-roll mill has the advantages of a relatively simple overall structure and a relatively reasonable spatial layout.
[0013] In some optional embodiments, two guide rods are provided, the two guide rods are vertically spaced apart, and each trigger plate is slidably provided on the corresponding two guide rods along the direction of the sliding path.
[0014] In the above technical solution, each mounting part is provided with two guide rods, so that each trigger plate can slide with the two guide rods at the same time, thereby making the trigger plate have the advantage of higher movement stability, so as to trigger the auxiliary emergency stop switch more stably, and at the same time, it can also improve the installation stability of the trigger plate itself.
[0015] In some optional embodiments, the trigger plate is provided with a through hole, and the trigger plate is sleeved on the guide rod through the through hole, so that the trigger plate can slide along the direction of the sliding path.
[0016] In the above technical solution, a hole is opened on the trigger plate and the trigger plate is sleeved on the guide rod through the opened through hole, which has the advantage of a relatively stable overall structure.
[0017] In some optional embodiments, the guide rod is provided with a first elastic member that can be compressed or restored along the direction of the sliding path, the trigger plate is located on the side of the first elastic member away from the auxiliary emergency stop switch, and when the first elastic member is compressed by the trigger plate, the trigger plate can trigger the auxiliary emergency stop switch.
[0018] In the above technical solution, a first elastic member that can be compressed or restored along the direction of the sliding path is added to the guide rod on the side close to the auxiliary emergency stop switch, so that during the normal operation of the equipment, the trigger plate will not contact and trigger the auxiliary emergency stop switch, that is, it will not interfere with the normal operation of the equipment. Moreover, when the trigger plate triggers the auxiliary emergency stop switch, it can automatically reset, which has high controllability.
[0019] In some optional embodiments, the guide rod has a first section close to the auxiliary emergency stop switch and a second section away from the auxiliary emergency stop switch, the first section is provided with a first elastic member, the second section is provided with a second elastic member that can be compressed or restored along the direction of the sliding path, and the trigger plate is clamped between the first elastic member and the second elastic member.
[0020] In the above technical solution, the guide rod is divided into two sections, and a second elastic member is added to the second section so that the trigger plate is clamped between the first elastic member and the second elastic member. During normal operation of the equipment, this setting can fix the trigger plate at a relatively suitable position on the guide rod, thereby facilitating the subsequent triggering of the auxiliary emergency stop switch by the trigger plate.
[0021] In some optional embodiments, in the direction of the sliding path, the size of the first elastic member is smaller than the size of the second elastic member.
[0022] In the above technical solution, the first elastic member is set to be smaller than the second elastic member, so that the distance between the trigger plate and the auxiliary emergency stop switch is smaller in the initial state, so that the auxiliary emergency stop switch can be triggered more timely.

[0036] The twin-roll mill provided in the present application is described in detail below.
[0037] See also Figure 1 and Figure 2 The embodiment of the present application provides a double-roll mill 10, comprising a base 100, two working rolls 200, an auxiliary trigger unit 300 and an auxiliary emergency stop switch 400. The base 100 has two mounting members 110 arranged opposite to each other; the two working rolls 200 are installed side by side between the two mounting members 110, and the two ends of each working roll 200 are respectively rotatably arranged on the two mounting members 110; the auxiliary trigger unit 300 includes a trigger rod 310, and the two ends of the trigger rod 310 are respectively slidably arranged on the two mounting members 110; the auxiliary emergency stop switch 400 is electrically connected to the control system of the double-roll mill 10, and the auxiliary emergency stop switch 400 is located on the sliding path of the trigger rod 310 and can be triggered by the trigger rod 310.
[0038] In the present application, the double-roll mill 10 is additionally provided with an auxiliary trigger unit 300 and an auxiliary emergency stop switch 400, wherein the two ends of the trigger rod 310 in the auxiliary trigger unit 300 are respectively slidably arranged on two mounting parts 110 (i.e., the trigger rod 310 spans the entire working roll 200), and the auxiliary emergency stop switch 400 is located on the sliding path of the trigger rod 310 and can be triggered by the trigger rod 310. Through the mutual cooperation of the trigger rod 310 and the auxiliary emergency stop switch 400, when an accident occurs and the equipment needs to be shut down, the trigger rod 310 occupies a large space and is slidable, and the operator can drive the trigger rod 310 through many positions of the body (such as the hand, head, and torso of the body, etc.), thereby shutting down the equipment. Compared with the traditional structure of the mill (usually the emergency stop switch can only be triggered by hand to shut down the equipment), after an accident occurs, the specific form of the double-roll mill 10 provided in the present application can shut down the equipment more promptly and conveniently, thereby reducing the probability of secondary accidents, so as to better protect the personal safety of the operator.
[0039] It should be noted that the form of the base 100 is not limited. For example, it can be a split form (that is, the two mounting parts 110 are also completely separated), or it can be an integrated form (that is, the two mounting parts 110 are also connected together). The embodiments of the present application all take the integrated setting as an example.
[0040] As an example, two auxiliary emergency stop switches 400 are provided, and the two auxiliary emergency stop switches 400 are respectively mounted on two mounting members 110 and are respectively located on two sliding paths at two ends of the trigger rod 310 .
[0041] In this embodiment, two auxiliary emergency stop switches 400 are provided. When one of the switches fails or malfunctions, the equipment can be shut down by triggering the other switch, which has the advantage of a higher safety factor.
[0042] As an example, the two auxiliary emergency stop switches 400 are located on the same side of the two sliding paths.
[0043] In this embodiment, the two auxiliary emergency stop switches 400 are arranged on the same side of the two sliding paths so that the two auxiliary emergency stop switches 400 can be triggered simultaneously each time, which has the advantage of a higher safety factor. At the same time, this arrangement also has the advantage of greater controllability.
[0044] In other possible implementations, in the direction of the sliding path, the two auxiliary emergency stop switches 400 may also be distributed at intervals, that is, located on both sides.
[0045] See also Figure 3 and Figure 4As an example, each mounting member 110 includes a mounting plate 111, a guide rod 112 and two mounting rods 113. The two mounting rods 113 are spaced apart and vertically protruded on the top of the mounting plate 111. Both ends of the guide rod 112 are respectively fixed to the two mounting rods 113, and the guide rod 112 is arranged along the extension direction of the sliding path. The auxiliary emergency stop switch 400 is located at the end of the sliding path; the trigger rod 310 includes a rod body 311 and trigger plates 312 located at both ends of the rod body 311. Each trigger plate 312 is slidably arranged on the corresponding guide rod 112 along the direction of the sliding path.
[0046] In this embodiment, the mounting member 110 is configured in the form of a mounting plate 111, a guide rod 112 and two mounting rods 113 cooperating with each other, the trigger rod 310 is configured in the form of a rod body 311 and a trigger plate 312 cooperating with each other, and the trigger plate 312 is slidably arranged on the corresponding guide rod 112, so that the double-roll mill 10 has the advantages of a relatively simple overall structure and a relatively reasonable spatial layout.
[0047] It should be noted that the number of guide rods 112 is not limited and can be adjusted according to actual needs.
[0048] See also Figure 4 As an example, two guide rods 112 are provided, the two guide rods 112 are vertically spaced apart, and each trigger plate 312 is slidably provided on the corresponding two guide rods 112 along the direction of the sliding path.
[0049] In this embodiment, each mounting member 110 is provided with two guide rods 112, so that each trigger plate 312 can slide with the two guide rods 112 at the same time, thereby making the trigger plate 312 have the advantage of higher movement stability, so as to trigger the auxiliary emergency stop switch 400 more stably, and at the same time, it can also improve the installation stability of the trigger plate 312 itself.
[0050] It should be noted that the manner in which the trigger plate 312 and the guide rod 112 are slidably matched is not limited and can be set according to conventional options in the art.
[0051] As an example, the trigger plate 312 is provided with a through hole, and the trigger plate 312 is sleeved on the guide rod 112 through the through hole, so that the trigger plate 312 can slide along the direction of the sliding path.
[0052] In this embodiment, a hole is opened on the trigger plate 312 and the trigger plate 312 is sleeved on the guide rod 112 through the opened through hole, which has the advantage of a relatively stable overall structure.
[0053] As an example, in the trigger rod 310 , the vertical dimension of the rod body 311 is smaller than the vertical dimension of the trigger plate 312 .
[0054] In this embodiment, the above-mentioned specific configuration can effectively reduce the weight of the trigger rod 310, thereby making it easier to drive.
[0055] See also Figure 4 As an example, the guide rod 112 is provided with a first elastic member 1121 which can be compressed or restored along the direction of the sliding path, and the trigger plate 312 is located on the side of the first elastic member 1121 away from the auxiliary emergency stop switch 400, and when the first elastic member 1121 is compressed by the trigger plate 312, the trigger plate 312 can trigger the auxiliary emergency stop switch 400.
[0056] In this embodiment, a first elastic member 1121 that can be compressed or restored along the sliding path is added to the guide rod 112 on one side close to the auxiliary emergency stop switch 400, so that during the normal operation of the equipment, the trigger plate 312 will not contact and trigger the auxiliary emergency stop switch 400, that is, it will not interfere with the normal operation of the equipment, and when the trigger plate 312 triggers the auxiliary emergency stop switch 400, it can also automatically reset, which has high controllability.
[0057] As an example, the first elastic member 1121 is sleeved on the guide rod 112 , and two ends of the first elastic member 1121 are respectively connected to the trigger plate 312 and the corresponding mounting rod 113 .
[0058] In this embodiment, the above-mentioned specific form is used to install the first elastic member 1121, which has the advantage of strong structural stability.
[0059] It is understandable that if the trigger plate 312 is far away from the auxiliary emergency stop switch 400 , it is difficult to trigger the auxiliary emergency stop switch 400 in time. Based on this, the structure of the guide rod 112 can be optimized.
[0060] See also Figure 4 As an example, the guide rod 112 has a first section close to the auxiliary emergency stop switch 400 and a second section away from the auxiliary emergency stop switch 400, the first section is provided with a first elastic member 1121, and the second section is provided with a second elastic member 1122 that can be compressed or restored along the direction of the sliding path, and the trigger plate 312 is clamped between the first elastic member 1121 and the second elastic member 1122.
[0061] In this embodiment, the guide rod 112 is divided into two sections, and a second elastic member 1122 is added to the second section so that the trigger plate 312 is clamped between the first elastic member 1121 and the second elastic member 1122. During normal operation of the equipment, this setting can fix the trigger plate 312 at a relatively suitable position of the guide rod 112, thereby facilitating the subsequent triggering of the auxiliary emergency stop switch 400 by the trigger plate 312.
[0062] As an example, the second elastic member 1122 is sleeved on the guide rod 112 , and two ends of the second elastic member 1122 are respectively connected to the trigger plate 312 and the corresponding mounting rod 113 .
[0063] In this embodiment, the above-mentioned specific form is used to install the second elastic member 1122, which has the advantage of strong structural stability.
[0064] See also Figure 4 As an example, in the direction of the sliding path, the size of the first elastic member 1121 is smaller than the size of the second elastic member 1122.
[0065] In this embodiment, the first elastic member 1121 is set to be smaller than the second elastic member 1122, so that the distance between the trigger plate 312 and the auxiliary emergency stop switch 400 is smaller in the initial state, so that the auxiliary emergency stop switch 400 can be triggered more timely.
[0066] In other possible implementations, in the direction of the sliding path, the size of the first elastic member 1121 may also be equal to or larger than the size of the second elastic member 1122 .
[0067] As an example, the stiffness coefficient of the second elastic member 1122 is greater than the stiffness coefficient of the first elastic member 1121 .
[0068] In this embodiment, the stiffness coefficient of the second elastic member 1122 is set to be greater than the stiffness coefficient of the first elastic member 1121, so that when the deformation amount is the same, the second elastic member 1122 can provide a greater elastic force, thereby providing a better buffering and limiting effect for the trigger plate 312.
[0069] In other possible implementations, the stiffness coefficient of the second elastic member 1122 may also be equal to or less than the stiffness coefficient of the first elastic member 1121 .
[0070] It should be noted that any structural or functional unit not specifically described or limited in the twin-roll mill 10 is not limited and can be configured according to conventional selections in the art.
[0071] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
