Description

Technical Field

[0001] This utility model relates to the field of open mill technology, specifically to a rubber open mill for producing rubber hoses. Background Technology

[0002] In the production of rubber hoses, the open mill is a key piece of equipment, and its performance directly affects product quality and production efficiency. Traditional open mills have many shortcomings in terms of operational complexity, uniformity of material distribution, and stability of finished product quality.

[0003] According to the published specifications of the rubber open mill (publication number: CN203210548U), it includes a base, a first impeller, a second impeller, an adjusting wheel, and a motor. The first impeller is movably mounted on the base via a first shaft, the second impeller is movably mounted on the base via a second shaft, and the adjusting wheel is movably mounted on the base via an adjusting shaft. The motor is connected to and drives the first shaft, the first shaft is connected to and drives the adjusting shaft, and the adjusting shaft is connected to and drives the second shaft. The adjusting wheel consists of multiple coaxial impellers of different diameters. This rubber open mill provides a quick and convenient adjustment of the speed difference between the two impellers, thus adapting to the mixing operations of different types of rubber.

[0004] In the aforementioned application, the speed difference of the rollers is adjusted by adjusting the rollers and multiple coaxial rollers of different diameters. Although this improves the flexibility of rubber mixing operations to a certain extent, there are still problems such as uneven material distribution, complex operation, and unstable finished product quality when producing rubber pipes. Therefore, we propose a rubber open mill for producing rubber pipes. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a rubber open mill for producing rubber hoses, which solves the technical problems of complex operation, uneven material distribution, and unstable finished product quality of existing rubber open mills.

[0006] According to one aspect, at least one embodiment of the present invention provides a rubber open mill for producing rubber hoses, comprising: a workbench, an open mill disposed on the top of the workbench, a control panel disposed on the side of the open mill, and a rubber turning device disposed on the side of the workbench.

[0007] The rubber-turning device includes a mounting plate, which is fixedly connected to the inner side of the workbench. A motor is fixedly connected to the side of the mounting plate, and a drive gear is fixedly connected to the output shaft of the motor. A transmission plate is fixedly connected to the side of the workbench, and a transmission shaft is rotatably connected through the side of the transmission plate. A driven gear is fixedly connected to the circumferential surface of the transmission shaft, and a pulley is fixedly connected to one end of the transmission shaft. A fixed plate is fixedly connected to the side of the open mill, and a reciprocating screw is rotatably connected through the side of the fixed plate. A pulley is fixedly connected to one end of the reciprocating screw, and a belt is provided on the circumferential surface of the pulley. The pulley and pulley are connected by belt drive. A threaded sleeve is threadedly connected to the circumferential surface of the reciprocating screw, and a moving plate is fixedly connected to the circumferential surface of the threaded sleeve. A connecting post is provided on the side of the moving plate, and a scraper is provided at the end of the connecting post away from the moving plate. A limit post is fixedly connected to the side of the fixed plate.

[0008] For example, in a rubber open mill for producing rubber tubes provided in at least one embodiment of the present invention, a limiting plate is fixedly connected to one end of the reciprocating screw away from the pulley, and the side of the scraper is set to be arc-shaped, which is to better fit the surface of the rubber tube, thereby reducing damage to the rubber tube during the rubber turning process and improving the rubber turning efficiency.

[0009] The driving gear and the driven gear mesh with each other. The driving gear has more teeth than the driven gear. Its function is to adjust the transmission ratio by the difference in the number of teeth between the driving gear and the driven gear, so that the scraper can move at a higher speed.

[0010] The circumferential surface of the limiting post penetrates and slides through the side of the moving plate. There are two limiting posts, which are symmetrically distributed along the vertical central axis of the reciprocating screw. Their function is to limit the moving plate and prevent it from shifting or shaking during movement, so as to ensure that the scraper can stably perform the rubber-turning operation on the surface of the rubber tube.

[0011] There are two fixed plates, which are symmetrically distributed along the vertical central axis of the reciprocating screw. There are also two transmission plates. Their function is to improve the stability and load-bearing capacity of the entire glue-turning device and ensure smooth operation during the glue-turning process. At the same time, the design of the fixed plates and transmission plates also makes the structure of the entire device more balanced.

[0012] According to another aspect, at least one embodiment of the present invention also provides a rubber open mill for producing rubber hoses, comprising: a balancing device, wherein the balancing device is provided on the side of the open mill, the balancing device includes a driving bevel gear, the driving bevel gear is fixedly connected to the circumferential surface of a transmission shaft, a shaking plate is provided on the inner bottom of the worktable, a material tray is fixedly connected to the top of the shaking plate, a rack is fixedly connected to the bottom of the shaking plate, an auxiliary plate is fixedly connected to the side of the open mill, a transmission shaft is rotatably connected through the side of the auxiliary plate, a driven bevel gear is fixedly connected to one end of the transmission shaft, a half gear is fixedly connected to the end of the transmission shaft away from the driven bevel gear, a vibration spring is fixedly connected to the side of the shaking plate, and a vibration plate is fixedly connected to the side of the worktable, the function of which is to make the shaking plate vibrate to prevent the material from solidifying or sticking.

[0013] For example, in a rubber open mill for producing rubber tubes provided in at least one embodiment of the present invention, a vibration spring is further included. The end of the vibration spring away from the shaking plate is fixedly connected to the side of the vibration plate, and the bottom of the shaking plate is slidably connected to the inner side of the open mill. Its function is to ensure that the shaking plate can remain stable during vibration and achieve smooth sliding, so as to avoid material accumulation or jamming on the shaking plate.

[0014] The driving bevel gear and the driven bevel gear mesh with each other. The driving bevel gear has more teeth than the driven bevel gear. Its function is to adjust the transmission ratio by the difference in the number of teeth between the driving bevel gear and the driven bevel gear, so that the transmission shaft rotates at a suitable speed, thereby driving the half gear to rotate.

[0015] The rack and the half gear mesh with each other, and the side cross section of the shaking plate is set in a U-shape. Its function is to make the shaking plate move intermittently in the horizontal direction through the meshing relationship between the rack and the half gear.

[0016] The vibrating plate and vibrating spring are provided in two quantities and are symmetrically distributed along the vertical central axis of the worktable. The side cross-section of the vibrating plate is set in an L shape, which enhances the stability of the vibrating plate during vibration. At the same time, the L-shaped vibrating plate design can also better adapt to the structure of the worktable, ensuring that the vibration effect can be evenly transmitted to the vibrating plate, thereby improving the material dispersion efficiency.

[0017] The beneficial effects of the embodiments of this utility model are as follows: 1. This utility model achieves automated rubber tube turning through the cooperation of components such as the mounting plate, motor, and drive gear in the rubber turning device, reducing the tediousness and labor intensity of manual turning. Simultaneously, the design of components such as the reciprocating screw, threaded sleeve, and moving plate in the turning device ensures that the scraper can move stably on the surface of the rubber tube, guaranteeing uniformity and efficiency in turning. Furthermore, the inclusion of limiting posts and fixing plates in the turning device improves the stability and load-bearing capacity of the entire device, making the turning process smoother and more reliable.

[0018] 2. In this invention, the coordinated operation of components such as the active bevel gear, the shaking plate, and the material tray in the balancing device achieves balanced material feeding and agitation dispersion, preventing material accumulation and adhesion in the open mill and improving the production efficiency and quality of rubber hoses. Simultaneously, the design of components such as the transmission shaft, half-gear, and rack in the balancing device allows the shaking plate to move intermittently back and forth, further enhancing the material dispersion effect. Furthermore, the inclusion of components such as the vibration spring and vibration plate in the balancing device not only improves the stability of the shaking plate during vibration but also...

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0023] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product.

Therefore, they should not be construed as limitations on this utility model.

[0027] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] like Figures 1-5 As shown, it illustrates a rubber open mill for producing rubber tubes according to one embodiment of the present invention, including a workbench 1, an open mill 2 disposed on the top of the workbench 1, a control panel 3 disposed on the side of the open mill 2, and a rubber turning device 4 disposed on the side of the workbench 1.

[0029] The rubber-turning device 4 includes a mounting plate 401, which is fixedly connected to the inner side of the workbench 1. A motor 402 is fixedly connected to the side of the mounting plate 401, and a drive gear 403 is fixedly connected to the output shaft of the motor 402. A transmission plate 404 is fixedly connected to the side of the workbench 1, and a transmission shaft 405 is rotatably connected through the side of the transmission plate 404. A driven gear 406 is fixedly connected to the circumferential surface of the transmission shaft 405, and a pulley 407 is fixedly connected to one end of the transmission shaft 405. A fixing plate 408 is fixedly connected to the side of the open mill 2, and the side of the fixing plate 408 is... A reciprocating screw 409 is rotatably connected to the reciprocating screw 409. A pulley 410 is fixedly connected to one end of the reciprocating screw 409. A belt 411 is provided on the circumferential surface of the pulley 410. The pulley 407 and the pulley 410 are connected by the belt 411. A threaded sleeve 412 is threadedly connected to the circumferential surface of the reciprocating screw 409. A movable plate 413 is fixedly connected to the circumferential surface of the threaded sleeve 412. A connecting post 414 is provided on the side of the movable plate 413. A scraper 415 is provided at the end of the connecting post 414 away from the movable plate 413. A limit post 416 is fixedly connected to the side of the fixed plate 408.

[0030] In some examples, the end of the reciprocating screw 409 away from the pulley 407 is fixedly connected to a limiting plate 5, and the side of the scraper 415 is set to be arc-shaped, which is to better fit the surface of the rubber tube, thereby reducing damage to the rubber tube during the rubber turning process and improving the rubber turning efficiency.

[0031] The driving gear 403 and the driven gear 406 mesh with each other. The driving gear 403 has more teeth than the driven gear 406. Its function is to adjust the transmission ratio by the difference in the number of teeth between the driving gear 403 and the driven gear 406, so that the scraper 415 can move at a higher speed.

[0032] The circumferential surface of the limiting post 416 penetrates and slides through the side of the moving plate 413. There are two limiting posts 416, which are symmetrically distributed along the vertical central axis of the reciprocating screw 409. Their function is to limit the moving plate 413 to prevent it from shifting or shaking during movement, and to ensure that the scraper 415 can stably perform the rubber-turning operation on the surface of the rubber tube.

[0033] There are two fixed plates 408, which are symmetrically distributed along the vertical central axis of the reciprocating screw 409. There are two transmission plates 404. Their function is to improve the stability and load-bearing capacity of the entire glue-turning device 4 and ensure smooth operation during the glue-turning process. At the same time, the design of the fixed plates 408 and transmission plates 404 also makes the structure of the entire device more balanced.

[0034] For example, such as Figures 1-5 As shown, the material is first placed on the open mill 2, and then the motor 402 is started. The output shaft of the motor 402 drives the drive gear 403 to rotate. Since the drive gear 403 and the driven gear 406 mesh with each other, and the number of teeth of the drive gear 403 is greater than that of the driven gear 406, the driven gear 406 will rotate at a faster speed, thereby driving the transmission shaft 405 and pulley 407 to rotate. Pulley 407 is connected to pulley 410 via belt 411, so pulley 410 will also rotate, thereby driving the reciprocating screw 409 to rotate. The rotation of the reciprocating screw 409 will cause the threaded sleeve 412 to move on the reciprocating screw 409. Since the threaded sleeve 412 is fixedly connected to the moving plate 413, the moving plate 413 will also move accordingly. At the same time, the limiting post 416 limits the moving plate 413 to prevent it from deviating or shaking during movement, ensuring that the scraper 415 can stably perform the rubber turning operation on the surface of the rubber tube. During the rubber turning process, the arc-shaped side of the scraper 415 can better fit the surface of the rubber tube, thereby reducing damage to the rubber tube and improving the turning efficiency.

[0035] like Figures 1-5As shown, this illustrates a rubber open mill for producing rubber hoses according to another embodiment of the present invention. It includes a balancing device 6, which is located on the side of the open mill 2. The balancing device 6 includes a drive bevel gear 601, which is fixedly connected to the circumferential surface of the transmission shaft 405. A material shaking plate 602 is located at the bottom inner side of the worktable 1. A material tray 603 is fixedly connected to the top of the material shaking plate 602, and a rack 604 is fixedly connected to the bottom of the material shaking plate 602. An auxiliary plate 605 is fixedly connected to the side of the worktable 2. A transmission shaft 606 is rotatably connected through the side of the auxiliary plate 605. A driven bevel gear 607 is fixedly connected to one end of the transmission shaft 606. A half gear 608 is fixedly connected to the other end of the transmission shaft 606 away from the driven bevel gear 607. A vibration spring 609 is fixedly connected to the side of the shaking plate 602. A vibration plate 610 is fixedly connected to the side of the worktable 1. Its function is to make the shaking plate 602 shake to prevent the material from solidifying or sticking.

[0036] In some examples, the end of the vibration spring 609 away from the shaking plate 602 is fixedly connected to the side of the vibration plate (610), and the bottom of the shaking plate 602 is slidably connected to the inner side of the open mill 2. Its function is to ensure that the shaking plate 602 can remain stable during vibration, while achieving smooth sliding and avoiding material accumulation or jamming on the shaking plate 602.

[0037] The driving bevel gear 601 meshes with the driven bevel gear 607. The driving bevel gear 601 has more teeth than the driven bevel gear 607. Its function is to adjust the transmission ratio by the difference in the number of teeth between the driving bevel gear 601 and the driven bevel gear 607, so that the transmission shaft 606 rotates at a suitable speed, thereby driving the half gear 608 to rotate.

[0038] The rack 604 meshes with the half gear 608, and the side section of the shaking plate 602 is set in a U-shape. Its function is to make the shaking plate 602 move intermittently in the horizontal direction through the meshing relationship between the rack 604 and the half gear 608.

[0039] There are two vibration plates 610 and vibration springs 609, which are symmetrically distributed along the vertical central axis of the worktable 1. The side cross section of the vibration plate 610 is L-shaped, which enhances the stability of the shaking plate 602 during vibration. At the same time, the L-shaped vibration plate 610 design can also better adapt to the structure of the worktable 1, ensuring that the vibration effect can be evenly transmitted to the shaking plate 602, thereby improving the material dispersion efficiency.

[0040] For example, such as 1~ Figure 5As shown, when the drive shaft 405 rotates, the driving bevel gear 601 fixed on its circumference will rotate accordingly. Since the driving bevel gear 601 meshes with the driven bevel gear 607, and the driving bevel gear 601 has more teeth than the driven bevel gear 607, the driven bevel gear 607 will rotate at a faster speed, thereby driving the transmission shaft 606 and the half gear 608 to rotate. The rotation of the half gear 608 will intermittently mesh with the rack 604, causing the shaking plate 602 to intermittently reciprocate in the horizontal direction. This reciprocating movement helps to evenly disperse the material on the tray 603, preventing the material from solidifying or sticking together. The combined design of the vibration spring 609 and the vibration plate 610 can further enhance the vibration effect of the shaking plate 602. When the half gear 608 meshes with the rack 604, the shaking plate 602 is subjected to a forward thrust, at which point the vibration spring 609 is compressed. When the half gear 608 disengages from the rack 604, the vibration spring 609 releases energy, pushing the shaking plate 602 backward. This reciprocating vibration and movement helps to distribute the material more evenly on the material tray 603, improving production efficiency.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
