Description

Technical Field

[0001] This utility model belongs to the field of open mill technology, and more specifically, it relates to a precision open mill protection device. Background Technology

[0002] An open mixing mill is a type of plastic mixing machine that is widely used in the plastics industry. It is usually set before the calender and after the mixer to mix and plasticize the uniformly mixed feed material, providing a more uniformly mixed molten material for the calender to calender and mold plastic products.

[0003] In the existing technology, manual operation is required to place the material to be refined between two rotating rollers so that the material can be processed by the rotation and compression of the two rotating rollers. However, the temperature of the two rotating rollers is high when the open mill is working. When the material to be refined is added manually, it is easy to cause burns to personnel and there is a risk of being pinched by the rotating rollers, which is dangerous. Utility Model Content

[0004] The purpose of this utility model is to provide a precision open mill protection device, which aims to solve the technical problem that existing open mills are prone to causing personnel injuries and posing safety hazards when conveying materials to be refined.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a precision open mill protective device, comprising:

[0006] Two sets of mounting brackets are spaced apart and arranged opposite each other along the axial direction of the open mill rotating roller; one side of each set of mounting brackets is fixed to the open mill body, and the other side extends towards each other, with the extended side of the mounting brackets positioned above the rotating roller;

[0007] A feeding bin is located between the two sets of mounting frames and is detachably connected to the two sets of mounting frames; the feeding bin has a vertically penetrating feeding channel, which extends downward to above the rotating rollers; the feeding channel covers the periphery of the two sets of rotating rollers.

[0008] In one possible implementation, the mounting bracket includes:

[0009] Multiple lifting mechanisms are spaced apart along the axis perpendicular to the rotating roller, and their bottoms are all fixed to the open mill body, with their telescopic ends extending upward in the vertical direction;

[0010] The first mounting plate is fixed to the telescopic end of the lifting mechanism; the first mounting plate is detachably connected to the feeding hopper.

[0011] In some embodiments, the first mounting plate has a first Z-shaped cross-section, one side of the first Z-shaped structure is fixed to the telescopic end of the lifting mechanism, and the other side extends upward toward the rotating roller; wherein the feeding bin overlaps the extended side of the first mounting plate and abuts against the longitudinal rib portion of the first Z-shaped structure.

[0012] For example, a limiting rod is provided between the feeding bin and the first mounting plate. One end of the limiting rod passes vertically through the feeding bin and the first mounting plate, and the other end is limited on the feeding bin.

[0013] In one possible implementation, the feeding bin is provided with two sets of spaced-apart first conveying rollers, which are arranged parallel to the rotating rollers; in a horizontal direction perpendicular to the axial direction of the rotating rollers, the two sets of first conveying rollers are placed outside the two sets of rotating rollers and close to the front and rear side walls of the feeding bin.

[0014] In some embodiments, the inner wall of the feed bin extends inward at an angle and surrounds the outer side of the first conveyor roller.

[0015] In one possible implementation, the bottom of the feeding bin is provided with second conveying rollers at intervals, the second conveying rollers being arranged perpendicular to the axial direction of the rotating roller; along the axial direction of the rotating roller, two sets of the second conveying rollers are respectively arranged directly below the left and right side walls of the feeding bin.

[0016] In some embodiments, a second mounting plate is provided at the bottom of the two sets of mounting frames, and the mounting frames are fixed to the open mill body by the second mounting plate; one side of the second mounting plate extends to the bottom of the feeding hopper and is connected to the second conveying roller.

[0017] For example, the second mounting plate has a second Z-shaped structure, one side of which is fixed to the open mill body, and the other side extends horizontally to near the bottom of the feed hopper and is connected to the second conveying roller.

[0018] In some embodiments, each of the second conveying rollers has a set of connecting plates at both ends, the connecting plates extending along the axial direction of the rotating roller and fixed to the second mounting plate.

[0019] Compared with the prior art, the solution shown in this application uses a mounting frame to fix the position of the feeding bin. By setting up the feeding bin, the material to be processed can be transported through the feeding channel of the feeding bin to the space between the two sets of rotating rollers, avoiding direct contact between the two sets of rotating rollers and effectively separating the distance between the operator and the rotating rollers, thus preventing injury to the operator. At the same time, the enclosed feeding bin can prevent splashing particles generated during the processing of the material to be processed from accidentally injuring the operator, effectively improving the safety of operation. On the other hand, the feeding bin and the mounting frame are detachably connected, which can facilitate the installation, disassembly and cleaning of the feeding bin. At the same time, the feeding channel is covered around the rotating rollers, which can ensure that the material to be processed can smoothly enter the rotating rollers for processing and prevent the material to be processed from scattering.

[0026] Please see Figure 1 The present invention provides a protective device for a precision open mill. The protective device includes two sets of mounting frames 1 and a feeding bin 2. The two sets of mounting frames 1 are spaced apart and arranged opposite each other along the axial direction of the rotating rollers 3 of the open mill. One side of each set of mounting frames 1 is fixed to the open mill body 4, and the other side extends towards each other, with the extended side of the mounting frame 1 positioned above the rotating rollers 3. The feeding bin 2 is located between the two sets of mounting frames 1 and is detachably connected to them. The feeding bin 2 has a vertically penetrating feeding channel that extends downwards above the rotating rollers 3. The feeding channel covers the periphery of the two sets of rotating rollers 3.

[0027] It should be noted that the open mill includes an open mill body 4, which includes a base and a left drive box and a right drive box mounted on the base. Two sets of rotating rollers 3 are located between the left drive box and the right drive box. The two mounting brackets 1 in this application are respectively mounted on the left drive box and the right drive box. The feeding bin 2 is mounted between the two sets of mounting brackets 1 and is positioned above the rotating rollers 3.

[0028] It should be understood that the feeding channel is installed around the two sets of rotating rollers 3 so as to transport the material to be refined between the two rotating rollers 3 and ensure maximum conveying efficiency, and avoid interference of the feeding bin 2 with the conveying of the material to be refined.

[0029] Optionally, the feeding bin 2 is a box-type structure, and the feeding channel runs through the upper and lower sides of the box-type structure so that the material to be refined can pass through the feeding bin 2.

[0030] Optionally, the mounting frame 1 can be a support structure made of channel steel or I-beams, which is convenient for material sourcing; and the feeding bin 2 is fixed to the channel steel of the mounting frame 1 by bolts or screws and other threaded connectors.

[0031] Compared with the prior art, the precision open mill protective device provided by this utility model has an installation frame 1 used to fix the position of the feeding bin 2. By setting the feeding bin 2, the material to be processed can be transported through the feeding channel of the feeding bin 2 to the space between the two sets of rotating rollers 3, avoiding direct contact between the two sets of rotating rollers 3 and the operator, effectively separating the distance between the operator and the rotating rollers 3, and preventing the operator from being injured. At the same time, the enclosed feeding bin 2 can prevent the splashing particles generated by the material to be processed during the processing from accidentally injuring the operator, effectively improving the safety of operation. On the other hand, the feeding bin 2 is detachably connected to the installation frame 1, which can facilitate the installation, disassembly and cleaning of the feeding bin 2. At the same time, the feeding channel is covered around the rotating rollers 3, which can ensure that the material to be processed can smoothly enter the rotating rollers 3 for processing and prevent the material to be processed from scattering.

[0032] Please see Figure 1 In some possible embodiments, the mounting frame 1 includes a plurality of lifting mechanisms 11 and a first mounting plate 12; the plurality of lifting mechanisms 11 are spaced apart along the axis perpendicular to the rotating roller 3, and the bottom of each mechanism is fixed to the open mill body, and the telescopic ends extend upward in the vertical direction; the first mounting plate 12 is fixed to the telescopic ends of the lifting mechanisms 11; the first mounting plate 12 is detachably connected to the feeding bin 2.

[0033] The lifting mechanism 11 is used to drive the first mounting plate 12 to rise and fall, thereby changing the position of the first mounting plate 12 and adjusting the relative height between the feeding bin 2 and the rotating roller 3. In this application, the first mounting plate 12 is driven to rise and fall by the telescopic end of the lifting mechanism 11, and the height of the feeding bin 2 can be adjusted according to different processing requirements, which is highly adaptable.

[0034] It should be understood that the size and dimensions of the materials to be refined vary. When the length of the materials to be refined is large, if the materials to be refined are placed directly in the feeding hopper 2, the bottom of the materials to be refined can be effectively supported, but the top of the materials to be refined is suspended. When the support of the materials to be refined is unstable, or when the rotating roller 3 clamps the materials to be refined, causing separation of the upper and lower parts, the support stability of the materials to be refined will be reduced. In this application, the support position of the first mounting plate 12 can be raised by the lifting mechanism 11, thereby moving the support position of the materials to be refined upward, thereby improving the support stability of the materials to be refined.

[0035] Furthermore, the first mounting plate 12 is fixed to the telescopic end of the lifting mechanism 11 and is detachably connected to the feeding bin 2, which facilitates the replacement or adjustment of the position and angle of the feeding bin 2 according to the actual situation.

[0036] Optionally, the lifting mechanism 11 can be one of an electric push rod, a telescopic drive cylinder, or a telescopic drive hydraulic cylinder, and its specific structure can be selectively set according to actual needs.

[0037] Please see Figure 1In some embodiments, the cross-section of the first mounting plate 12 is a first Z-shaped structure, one side of the first Z-shaped structure is fixed to the telescopic end of the lifting mechanism 11, and the other side extends above the rotating roller 3; wherein, the feeding bin 2 overlaps the extended side of the first mounting plate 12 and abuts against the longitudinal rib portion of the first Z-shaped structure.

[0038] By setting the first mounting plate 12 as a first Z-shaped structure, it is convenient to fix one side of the first mounting plate 12 while connecting the feeding bin 2 through the other side. Specifically, the first Z-shaped structure includes a first horizontal part, a first vertical part, and a second horizontal part. The first horizontal part is fixed to the telescopic end of the lifting mechanism 11, the first vertical part is the longitudinal rib part, and one side of the first vertical part abuts against the left drive box or the right drive box. The second horizontal part is used to connect the feeding bin 2.

[0039] In addition, the feeding bin 2 is attached to the second horizontal part of the first mounting plate 12, and the end of the feeding bin 2 abuts against the longitudinal rib. This structural design increases the stability and firmness of the feeding bin 2 installation, prevents the feeding bin 2 from shaking between the two mounting frames 1, and can better support the feeding bin 2.

[0040] Optionally, the feeding bin 2 includes an overlapping portion arranged in a rectangular ring and a box-shaped structure connected to the bottom of the rectangular ring structure, and the feeding channel passes through the rectangular ring structure and the box-shaped structure.

[0041] Please see Figure 1 For example, a limiting rod 13 is provided between the feeding bin 2 and the first mounting plate 12. One end of the limiting rod 13 passes through the feeding bin 2 and the first mounting plate 12 in a vertical direction, and the other end is limited on the feeding bin 2.

[0042] A limiting rod 13 is installed between the feeding bin 2 and the first mounting plate 12. One end passes through both and the other end is limited on the feeding bin 2. This can prevent the feeding bin 2 from shaking or shifting during operation and ensure the stability and accuracy of feeding.

[0043] Meanwhile, the limiting rod 13 is detachably connected to the feeding bin 2 and the first mounting plate 12, which makes it easy to remove the feeding bin 2. On the one hand, it facilitates the disassembly and maintenance of the feeding bin 2 and the rotating roller 3. On the other hand, when the size of the material to be refined is large, the feeding bin 2 can be removed so that the material to be refined can be directly conveyed against the mounting frames 1 on both sides, thus improving the practicality of the device.

[0044] Optionally, the limiting rod 13 includes a connecting part passing through the feeding bin 2 and the first mounting plate 12 and a limiting part limiting the feeding bin 2. Specifically, the cross-sectional dimension of the limiting part is larger than the size of the through hole of the connecting part.

[0045] Please see Figure 1In some possible embodiments, the feeding bin 2 is provided with two sets of first conveying rollers 21 spaced apart, the first conveying rollers 21 being arranged parallel to the rotating rollers 3; in the horizontal direction perpendicular to the axial direction of the rotating rollers 3, the two sets of first conveying rollers 21 are placed outside the two sets of rotating rollers 3 and close to the front and rear side walls of the feeding bin 2.

[0046] By setting two sets of first conveying rollers 21 spaced apart and parallel to the rotating rollers 3 in the feeding bin 2, the material conveying can be assisted, allowing the material to enter the rotating rollers 3 more smoothly and improving processing efficiency. At the same time, the friction between the material to be refined and the inner wall of the feeding channel is reduced, ensuring conveying efficiency.

[0047] Please see Figure 1 In some embodiments, the inner wall of the feeding bin 2 extends inward at an angle and surrounds the outside of the first conveying roller 21.

[0048] In addition, the inner wall of the feeding bin 2 extends inward at an angle and surrounds the outside of the first conveying roller 21, which is conducive to the concentration of materials in the middle and facilitates subsequent processing.

[0049] Optionally, the feeding bin 2 is inclined inward along the left and right side walls along the axis of the rotating roller 3, and the feeding bin 2 extends vertically along the front and rear side walls perpendicular to the axis of the rotating roller 3, so as to achieve centralized guidance of the material to be refined.

[0050] Please see Figure 1 In some possible embodiments, the bottom of the feeding bin 2 is provided with second conveying rollers 5 at intervals, and the second conveying rollers 5 are arranged perpendicular to the axial direction of the rotating roller 3; on the axial direction of the rotating roller 3, two sets of second conveying rollers 5 are respectively arranged directly below the left and right side walls of the feeding bin 2.

[0051] By setting second conveying rollers 5 perpendicular to the axis of the rotating roller 3 at intervals at the bottom of the feeding bin 2, the material to be refined conveyed to the lower part of the feeding channel is further guided, which enhances the material conveying capacity, ensures that the material can be supplied to the rotating roller 3 in a timely and uniform manner, and improves the continuity of production.

[0052] Furthermore, by setting a second conveying roller 5, it is possible to prevent the material to be refined from shifting during the conveying process, which would cause the material to be refined to be conveyed to the end of the rotating roller 3 and affect the rotation of the rotating roller 3.

[0053] Please see Figure 1 In some embodiments, a second mounting plate 6 is provided at the bottom of the two sets of mounting frames 1, and the mounting frame 1 is fixed to the open mill body 4 by the second mounting plate 6; one side of the second mounting plate 6 extends to the bottom of the feeding bin 2 and is connected to the second conveying roller 5.

[0054] By setting a second set of mounting plates 6 at the bottom of the two sets of mounting frames 1, the second conveying roller 5 can be installed, making the structure of the entire protective device more stable, and also facilitating the installation and fixing of the second conveying roller 5.

[0055] Optionally, as another example of the installation of the second conveying roller 5, the second conveying roller 5 is connected to the outer peripheral wall of the feeding bin 2 via a third mounting plate 12.

[0056] Please see Figure 1 For example, the second mounting plate 6 has a second Z-shaped structure. One side of the second Z-shaped structure is fixed to the open mill body 4, and the other side extends horizontally to near the bottom of the feeding bin 2 and is connected to the second conveying roller 5.

[0057] By configuring the second mounting plate 6 as a second Z-shaped structure, it is convenient to fix one side of the first mounting plate 12 while connecting the second conveyor roller 5 through the other side. Specifically, the second Z-shaped structure includes a third horizontal part, a second vertical part, and a fourth horizontal part. The third horizontal part is fixed to the open mill body 4, specifically to the left drive box and the right drive box. One side of the second vertical part abuts against the left drive box or the right drive box. The second horizontal part is used to connect the second conveyor roller 5. The second vertical part is used to lower the mounting position of the second conveyor roller 5 to avoid interference between the second conveyor roller 5 and the feed hopper 2.

[0058] The second Z-shaped structure ensures installation stability and makes reasonable use of space, making the layout of the entire protective device more compact.

[0059] Please see Figure 1 In some embodiments, each of the second conveying rollers 5 has a set of connecting plates 7 at both ends. The connecting plates 7 extend along the axial direction of the rotating roller 3 and are fixed to the second mounting plate 6.

[0060] Each of the second conveyor rollers 5 has a set of connecting plates 7 at both ends. The connecting plates 7 can be used to fix the second conveyor rollers 5 to the open mill body 4, which further enhances the installation strength and stability of the second conveyor rollers 5 and ensures that they can work normally.

[0061] The precision open mill protection device provided in this application can achieve comprehensive protection for the open mill, and at the same time play a good role in material conveying and processing, which can effectively improve production efficiency and safety, and reduce losses caused by equipment failure or improper operation.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
