Description

Technical Field

[0002] Calender is an industrial equipment, mainly used in rubber, plastic and textile industries, used to calender materials into uniform thin sheets. It is mainly composed of a feeding assembly and two or more rollers. By adjusting the roller distance and temperature, the continuous extension and forming of the material can be achieved. Calender is widely used in the production of rubber sheets, rubber sheets, as well as in processes such as glue sticking and rubbing. It is a key equipment for manufacturing rubber and plastic products.

[0003] The prior art also proposes some solutions. For example, a Chinese patent with announcement number CN214137001U discloses a high-efficiency thermally conductive silicone calender feeding device, including a feed hopper, a feed bin arranged at the bottom of the feed hopper, a conical stirring barrel penetrating the feed bin, and a screw feeder arranged in the conical stirring barrel. An overflow prevention device is provided on the outside of the feed hopper to prevent the overflow of raw materials. A driving device for driving the screw feeder is provided in the feed hopper. The feeding function of the raw materials is realized through the feed hopper, and the raw materials are fed into the feed hopper, and then stirred and fed by the screw feeder to make the raw materials mixed more fully. Then, the overflow prevention function of the raw materials is realized through the overflow prevention device, that is, the wedge-shaped overflow prevention sleeve provides the function of limiting and draining the raw materials.

[0004] The calender feeding device in the above technology delivers the mixed material to the feed port through a screw feeder.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8As shown, a uniform feeding device for a calender according to an embodiment of the present invention is suitable for a calender, the calender comprises a calender body 1 and a feed hopper 2, the feeding device comprises a mixing barrel 3; both sides of the mixing barrel 3 are rotatably connected with a rotating rod 4; the surface of the rotating rod 4 is rotatably connected with a support arm 5, and the support arm 5 is L-shaped; a connecting seat 6 is provided at one end of the two support arms 5 away from the mixing barrel 3, and the connecting seat 6 is fixedly connected to the calender body 1 by bolts; both sides of the connecting seat 6 are at corresponding positions of the support arm 5 The support arms 5 are all fixedly connected with rotating columns 7; the support arms 5 are rotatably connected to the surface of the rotating columns; the support arms 5 are driven by the driving components at the connecting seat 6; the bottom of the mixing barrel 3 is fixedly connected with a guide bucket 8; the top of the mixing barrel 3 is fixedly connected with a support frame 9; a servo motor 10 is installed on the surface of the support frame 9; the output shaft of the servo motor 10 is fixedly connected with a pair of symmetrically arranged stirring blades 11; an electric control valve is installed inside the guide bucket 8 and near the bottom; when working, in order to make the material poured into the feed hopper 2 more uniform, the embodiment of the present invention can be used, first The user needs to pour the material into the mixing barrel 3 first, then the servo motor 10 on the support frame 9 starts working and drives the stirring blade 11 to stir the material in the mixing barrel 3, so that the materials are mixed more evenly. Then the user drives the support arm 5 to rotate on the surface of the rotating column 7 through the driving assembly at the connecting seat 6. In the process of the support arm 5 driving the mixing barrel 3 to rotate to the top of the feed hopper 2, the user also needs to hold the mixing barrel 3 at the connecting rod so that the mixing barrel 3 can maintain a vertical state by its own gravity, and then open the electric control valve at the guide bucket 8 so that the mixed material enters the guide bucket 8 from the mixing barrel 3, and then enters the feed hopper 2 of the calender from the guide bucket 8. Finally, the guide bucket 8 guides the material into the feed hopper 2, and then completes the feeding operation. The mixing barrel 3 is driven to rotate to the top of the feed hopper 2 by the support arm 5, so that the material can fall into the feed hopper 2 with the help of gravity, thereby avoiding the residue of the material in the mixing barrel 3. At the same time, the stirring blades stir the internal materials of the mixing barrel 3, which can also ensure that the materials are mixed more evenly, thereby improving the final product quality.

[0023] like Figures 1 to 6As shown, the driving assembly includes a driving ring 12; the driving ring 12 is rotatably connected to the surface of the connecting seat 6, and the driving ring 12 is driven by the motor inside the connecting seat 6; a driving rod 13 is installed on the surface of the driving ring 12; a slot 14 is provided on the surface of the supporting arm 5 close to the driving rod 13 at a position corresponding to the driving rod 13, and the slot 14 is adapted to the driving rod 13; a gear set 15 is installed between the rotating rod 4 and the rotating column 7; during operation, when the user needs to rotate the supporting arm 5, the user needs to drive the control motor to drive the driving ring 12 to rotate, and then the driving ring 12 will drive the driving rod 13 to rotate, and because the driving rod 13 and the supporting arm 5 are connected The driving rod 13 is connected through the card slot 14, so the driving rod 13 can drive the supporting arm 5 to rotate. During the rotation of the supporting arm 5, the gear located at the end of the rotating column 7 in the gear set 15 will not rotate, and the supporting arm 5 will drive the other gears in the gear set 15 on its surface to rotate around the gear at the rotating column 7, so that the gear on the surface of the supporting arm rotates, and then the rotation is transmitted to the rotating rod 4, and then the rotating rod 4 drives the mixing barrel 3 to rotate, and finally the rotating column 7 drives the rotating rod 4 to rotate at the same time through the gear set 15, so that during the rotation of the supporting arm 5, the mixing barrel 3 is always kept in a vertical state, thereby preventing the material in the mixing barrel 3 from spilling out due to the tilt of the mixing barrel 3.

[0024] like Figure 3 and Figure 8 As shown, the bottom of the guide bucket 8 is slidably connected with a connecting pipe 16; the surface of the connecting pipe 16 is slidably connected with an extension pipe 17; the bottom surface of the extension pipe 17 is fixedly connected with an outer cover 18; the outer cover 18 is arranged in a trumpet shape, and the bottom area of ​​the bottom is larger than its top area; during operation, when the mixing barrel 3 rotates to the top of the feed hopper 2, the user needs to slide the extension pipe 17 on the surface of the connecting pipe 16 toward the feed hopper 2, and make the outer cover 18 at the bottom of the extension pipe 17 cover the inner wall of the feed hopper 2, so as to prevent the material from splashing to the outside of the feed hopper 2 during the pouring process.

[0025] like Figure 1 , Figure 2 Figure 5 and Figure 6As shown, the top surface of the calender body 1 and the side away from the connecting seat 6 are fixedly connected to a limiting frame 19; the top of the limiting frame 19 is adapted to the surface of the mixing barrel 3; the surface of the support arm 5 is provided with a slide groove 20 at the bottom of the slot 14, and the slot 14 is connected to the slide groove 20; the surface of the support frame 9 is fixedly connected with a push rod 21 at the corresponding position of the slot 14; the end of the push rod 21 away from the support frame 9 is fixedly connected with a push block 22, and the cross-section of the push block 22 is circular; the driving rod 13 is slidably connected to the driving ring 12; the side of the driving rod 13 and the driving ring 12 close to the center of the circle is fixedly connected with a spring 23; the driving The surface of the ring 12 is fixedly connected with a plurality of evenly arranged convex teeth 24; the surface of the extension tube 17 is installed with a tooth plate 25; the tooth plate 25 is slidably connected to the support arm 5, and the tooth plate 25 is meshedly connected with the convex teeth 24; during operation, when the support arm 5 rotates from a horizontal state to a vertical state, the mixing barrel 3 at the end of the support arm 5 will be blocked by the limit frame 19 and will be located directly above the feed hopper 2, and at the same time, the stop rod 21 on the surface of the limit frame 19 and the stop block 22 at its end will squeeze the driving rod 13 at the slot 14, so that the driving rod 13 at the slot 14 slides from the slot 14 to the slide groove 20 and compresses the spring 23. The driving rod 13 is located in the slide groove 20, so the driving ring 12 will continue to rotate, thereby driving the driving rod 13 on its surface to continue to slide along the slide groove 20 on the surface of the rotating arm, so that the convex teeth 24 on the surface of the driving ring 12 are engaged with the tooth plate 25, and drive the tooth plate 25 to move downward, thereby bringing the extension tube 17 connected thereto to move downward, thereby completing the automatic drop of the extension tube 17. At the same time, after the unloading is completed, when the driving ring 12 needs to drive the support arm 5 to return to the initial horizontal state, the connecting rod will return from the slide groove 20 to the bottom of the card slot 14, thereby driving the extension tube 17 and the outer cover 18 to rise, so that the outer cover 1 8 is separated from the feed hopper 2, and then the support arm 5 gradually moves away from the limit frame 19, and the stop block 22 no longer blocks the driving rod 13. At this time, the compressed spring 23 recovers, thereby driving the driving rod 13 to return to the card slot 14 to complete the control of the support arm 5 to rotate to a horizontal state, thereby achieving the support arm 5 driven by the driving ring 12 and the driving rod 13 to rotate, while also driving the extension tube 17 to slide on the connecting tube 16, so that the outer cover 18 at the bottom of the extension tube 17 can be automatically inserted into and pulled out of the feed hopper 2, thereby avoiding manual operation of the user, reducing the operating difficulty of the example of the present invention, and improving the usability of the embodiment of the present invention.

[0026] like Figure 1 , Figure 2 and Figure 7As shown, a pair of symmetrically arranged limit rods 26 are fixedly connected to the surface of the support frame 9 at the corresponding positions of the guide bucket 8; a sleeve 27 is sleeved on the surface of the limit rod 26; a plurality of uniformly arranged spring pieces 28 are fixedly connected between the inner wall of the sleeve 27 and the limit rod 26, and the spring pieces 28 are respectively located on both sides of the limit rod 26; during operation, when the mixing barrel 3 rotates to the limit frame 19, the guide bucket 8 will squeeze the sleeve 27 on the surface of the limit rod 26, so that the sleeves 27 on both sides move toward the two sides of the guide bucket 8, and through the spring piece 28 between the sleeve 27 and the limit rod 26, the sleeve 27 can clamp the guide bucket 8, thereby limiting the mixing barrel 3 fixed to the guide bucket 8, and preventing the mixing blade from causing the mixing barrel 3 to shake when working, or after the driving rod 13 enters the slide groove 20, the restriction of the driving rod 13 and the card slot 14 is released, resulting in the rotation of the support arm 5, the mixing barrel 3 and the guide bucket 8 in the vertical state.

[0027] like Figure 7 As shown, a conical tube 29 is fixedly connected to one end of the sleeve 27 away from the support frame 9; a protrusion 30 is fixedly connected to one end of the conical tube 29 away from the sleeve 27, and the protrusion 30 is arranged in an arc shape; during operation, when the guide bucket 8 rotates to between the two sleeves 27, the guide bucket 8 will first contact the protrusion 30. Since the protrusion 30 is arranged in an arc shape, the guide bucket 8 can smoothly pass through the two protrusions 30, and through the guidance of the conical tube 29, the guide bucket 8 can finally enter between the two sleeves 27, avoiding the guide bucket 8 being directly blocked by the end of the sleeve 27 during the process of turning to the two sleeves 27, and being unable to enter between the two sleeves 27.

[0028] like Figure 3 to Figure 4 As shown, the bottoms of the two stirring blades 11 are fixedly connected with connecting plates 31; a screw rod 32 is fixedly connected between the two connecting plates 31; during operation, when the servo motor 10 drives the stirring blades 11 to rotate, the stirring blades 11 will also drive the connecting plates 31 and the screw rod 32 to rotate, and the material in the guide bucket 8 can also be brought up through the rotation of the screw rod 32, thereby further improving the mixing effect of the mixed materials in the mixing barrel 3 and the guide bucket 8.

[0029] like Figure 3 and Figure 8As shown, a feed port 33 is provided on one side of the mixing barrel 3; a guide plate 34 is rotatably connected to the bottom of the feed port 33; baffles 35 are fixedly connected to the outer wall of the mixing barrel 3 and both sides of the guide plate 34, and the baffles 35 are wedge-shaped; a cross plate 36 is fixedly connected between the two baffles 35 and near the top; during operation, when the user needs to pour materials into the mixing barrel 3, the user can make the top of the guide plate 34 lean against the cross plate 36, so that the feed port 33 is in an open state, so that the user can pour the material into the mixing barrel 3 along the guide plate 34. In this process, the baffles 35 on both sides of the guide plate 34 can also play a limiting role to prevent the material from overflowing from the two sides of the guide plate 34. Therefore, loading can avoid directly pouring the material from the top of the mixing barrel 3, which causes part of the material to splash out of the mixing barrel 3 due to the obstruction of the stirring blades.

[0030] like Figure 3 and Figure 8 As shown, the surface of the transverse plate 36 is threadedly connected with a push rod 37; the push rod 37 is arranged in an arc shape at one end close to the guide plate 34, and the surface of the push rod 37 contacts the surface of the guide plate 34; during operation, when the user has loaded the material, the user can screw the push rod 37 at the transverse plate 36 to squeeze the guide plate 34 at the end, and push the guide plate 34 back to the feed port 33, thereby closing the feed port 33 to prevent the material from splashing out of the feed port 33 during the rotation of the mixing barrel 3 and the stirring blade 11.

[0031] like Figure 3 and Figure 8 As shown, the top of the mixing barrel 3 is rotatably connected to a pair of symmetrically arranged cover shells 38; the two cover shells 38 are fixedly connected to the sides close to each other with magnet blocks 39; the two magnet blocks 39 attract each other; during operation, when the user needs to stir the material, the user can rotate the cover shells 38 so that the two cover shells 38 are buckled together and adsorbed together by the magnet blocks 39, thereby closing the top of the mixing barrel 3, thereby further preventing the material from splashing out of the mixing barrel 3 when the stirring blade 11 stirs the material in the mixing barrel 3.

[0032] During operation, in order to make the materials poured into the feed hopper 2 more uniform, the embodiment of the present invention can be used. First, the user needs to pour the materials into the mixing barrel 3. Then, the servo motor 10 on the support frame 9 starts to work and drives the stirring blade 11 to stir the materials in the mixing barrel 3, so that the materials are mixed more uniformly. Then, the user drives the support arm 5 to rotate on the surface of the rotating column 7 through the driving component at the connecting seat 6. In the process of the support arm 5 driving the mixing barrel 3 to rotate to the top of the feed hopper 2, the user also needs to hold the mixing barrel 3 at the connecting rod so that the mixing barrel 3 can be stirred by itself. Gravity maintains a vertical state, and then the electric control valve at the guide bucket 8 is opened, so that the mixed material enters the guide bucket 8 from the mixing barrel 3, and then enters the feed hopper 2 of the calender from the guide bucket 8, and finally the guide bucket 8 guides the material into the feed hopper 2, thereby completing the loading operation, thereby driving the mixing barrel 3 to rotate to the top of the feed hopper 2 through the support arm 5, so that the material can fall into the feed hopper 2 with the help of gravity, thereby avoiding the residue of material in the mixing barrel 3, and at the same time, the stirring of the internal material of the mixing barrel 3 by the stirring blade can also ensure that the material is mixed more evenly, thereby improving the final product quality.

[0033] When the user needs to rotate the support arm 5, the user needs to drive the control motor to drive the drive ring 12 to rotate, and then the drive ring 12 will drive the drive rod 13 to rotate. Since the drive rod 13 and the support arm 5 are connected by the card slot 14, the drive rod 13 can drive the support arm 5 to rotate. During the rotation of the support arm 5, the gear located at the end of the rotating column 7 in the gear set 15 will not rotate, and the support arm 5 will drive the other gears in the gear set 15 on its surface to rotate around the gear at the rotating column 7, so that the gear on the surface of the support arm rotates, and then the rotation is transmitted to the rotating rod 4, and then the rotating rod 4 drives the mixing barrel 3 to rotate, and finally the rotating column 7 drives the rotating rod 4 to rotate at the same time through the gear set 15, so that during the rotation of the support arm 5, the mixing barrel 3 is always kept in a vertical state, thereby avoiding the material in the mixing barrel 3 from spilling out due to the tilt of the mixing barrel 3.

[0034] When the mixing barrel 3 rotates to the top of the feed hopper 2, the user needs to slide the extension tube 17 on the surface of the connecting tube 16 toward the feed hopper 2, and make the outer cover 18 at the bottom of the extension tube 17 cover the inner wall of the feed hopper 2, so as to prevent the material from splashing to the outside of the feed hopper 2 during the pouring process.

[0035] In the process of the support arm 5 rotating from the horizontal state to the vertical state, the mixing barrel 3 at the end of the support arm 5 will be blocked by the limit frame 19 and will be located directly above the feed hopper 2. At the same time, the stop rod 21 on the surface of the limit frame 19 and the stop block 22 at its end will squeeze the driving rod 13 at the slot 14, so that the driving rod 13 at the slot 14 slides from the slot 14 to the slide groove 20 and compresses the spring 23. Since the driving rod 13 is located in the slide groove 20, the driving ring 12 will continue to rotate, thereby driving the driving rod 13 on its surface to continue to slide along the slide groove 20 on the surface of the rotating arm, so that the convex teeth 24 on the surface of the driving ring 12 are engaged with the tooth plate 25, and drive the tooth plate 25 to move downward, thereby bringing the extension tube 17 connected thereto to move downward, thereby completing the automatic drop of the extension tube 17. At the same time, after the unloading is completed, the driving ring When 12 needs to drive the support arm 5 back to the initial horizontal state, the connecting rod will return from the slide groove 20 to the bottom of the slot 14, thereby driving the extension tube 17 and the outer cover 18 to rise, so that the outer cover 18 is separated from the feed hopper 2, and then the support arm 5 gradually moves away from the limit frame 19, and the stop block 22 no longer blocks the driving rod 13. At this time, the compressed spring 23 is restored, thereby driving the driving rod 13 back to the slot 14 to complete the control of the support arm 5 to rotate to a horizontal state, thereby achieving the rotation of the support arm 5 by the driving ring 12 and the driving rod 13, and can also drive the extension tube 17 to slide on the connecting tube 16, so that the outer cover 18 at the bottom of the extension tube 17 can be automatically inserted into and pulled out of the feed hopper 2, thereby avoiding manual operation of the user, reducing the operating difficulty of the example of the present invention, and improving the ease of use of the embodiment of the present invention.

[0036] When the mixing barrel 3 rotates to the limit frame 19, the guide bucket 8 will squeeze the sleeve 27 on the surface of the limit rod 26, so that the sleeves 27 on both sides move toward the two sides of the guide bucket 8, and through the spring piece 28 between the sleeve 27 and the limit rod 26, the sleeve 27 can clamp the guide bucket 8, thereby limiting the mixing barrel 3 fixed to the guide bucket 8, to prevent the mixing barrel 3 from shaking when the stirring blade is working, or after the driving rod 13 enters the slide groove 20, the restriction of the driving rod 13 and the card groove 14 is released, causing the support arm 5, the mixing barrel 3 and the guide bucket 8 in the vertical state to rotate.

[0037] When the guide bucket 8 rotates to between the two sleeves 27, the guide bucket 8 will first contact the protrusion 30. Since the protrusion 30 is arranged in an arc shape, the guide bucket 8 can smoothly pass through the two protrusions 30 and be guided by the tapered tube 29 so that the guide bucket 8 can finally enter between the two sleeves 27, thereby avoiding the guide bucket 8 being directly blocked by the end of the sleeve 27 during the process of turning to the two sleeves 27 and being unable to enter between the two sleeves 27.

[0038] When the servo motor 10 drives the stirring blade 11 to rotate, the stirring blade 11 will also drive the connecting plate 31 and the screw rod 32 to rotate. The material in the guide bucket 8 can also be brought up through the rotation of the screw rod 32, thereby further improving the mixing effect of the mixed materials in the mixing barrel 3 and the guide bucket 8.

[0039] When the user needs to pour the material into the mixing barrel 3, the user can make the top of the guide plate 34 lean against the cross plate 36, so that the feed port 33 is in an open state, thereby the user can pour the material into the mixing barrel 3 along the guide plate 34. In this process, the baffles 35 on both sides of the guide plate 34 can also play a limiting role to prevent the material from overflowing from both sides of the guide plate 34. In this way, the material can be prevented from being poured directly from the top of the mixing barrel 3, which may cause part of the material to splash out of the mixing barrel 3 due to the obstruction of the stirring blades.

[0040] When the user has finished loading the materials, the user can screw the push rod 37 at the horizontal plate 36 to squeeze the guide plate 34 at the end, and push the guide plate 34 back to the feed port 33, thereby closing the feed port 33 to prevent the materials from splashing out of the feed port 33 during the rotation of the mixing barrel 3 and the stirring blade 11.

[0041] When the user needs to stir the material, the user can rotate the cover 38 so that the two cover shells 38 are buckled together and adsorbed together by the magnet block 39, thereby closing the top of the mixing barrel 3, thereby further preventing the material from splashing out of the mixing barrel 3 when the stirring blade 11 stirs the material in the mixing barrel 3.

[0042] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
