DETAILED DESCRIPTION

[0021] In order to make the purpose, technical scheme and advantages of the present application more clear, the following embodiments are further described in detail.

[0022] Reference is made to Figure 1 ​​The embodiment of the application provides a roller device for a cylindrical barrel with a diameter greater than a length, which can be used for mounting workpieces in a compressor and the like. The device comprises a base 10, a first roller 20, a second roller 30, a driving mechanism 40, a stand 50 and a pressing mechanism 60. The first roller 20 and the second roller 30 are arranged in parallel along the axis and are adjustably connected to the base 10; the driving mechanism 40 is arranged on the base 10 and is connected to the first roller 20 and the second roller 30, and is used for driving the first roller 20 and the second roller 30 to rotate; and the pressing mechanism 60 is movably connected to the stand and corresponds to the position between the first roller 20 and the second roller 30.

[0023] The first roller 20 and the second roller 30 in the embodiment of the application can be used for placing a cylindrical barrel with a diameter greater than an axial length (for example, the cylindrical barrel with a diameter ranging from 200mm to 3000mm and an axial length ranging from 100mm to 1000mm, and the ratio of the diameter to the axial length is greater than or equal to 1), the first roller 20 and the second roller 30 are driven to rotate by the driving mechanism 40, and then the cylindrical barrel is driven to rotate, and the pressing mechanism 60 is pressed on the top of the cylindrical barrel, thereby solving the problem that the cylindrical barrel with a length less than a diameter is easy to fall down, and ensuring the stability of the cylindrical barrel during the mounting process. In addition, since the first roller 20 and the second roller 30 can drive the cylindrical barrel to rotate, the position of the cylindrical barrel to be mounted is at a low place, which is convenient for the operator to install, not only reduces various safety hazards that may be caused by the operator due to climbing when installing various parts, but also reduces the working hours wasted by the operator due to multiple lifting, walking, carrying and the like, and improves the production efficiency.

[0024] The technical scheme of the embodiment of the application will be described in detail below with reference to the drawings.

[0025] Referring to Figure 1 The roller device for a cylindrical barrel with a diameter greater than a length according to the embodiment of the application comprises a base 10, a first roller 20, a second roller 30, a driving mechanism 40, a stand 50 and a pressing mechanism 60.

[0026] The first roller 20 and the second roller 30 are arranged in parallel along the axis and are adjustably connected to the base 10, and the first roller 20 and the second roller 30 are used for placing a cylindrical barrel (not shown in the figure).

[0027] The first roller 20 and the second roller 30 are arranged in parallel and are adjustably connected to the base 10. In particular, the first roller 20 and the second roller 30 can be adjustably connected to the base 10; or the first roller 20 can be fixedly connected to the base 10, and the second roller 30 can be adjustably connected to the base 10; or the second roller 30 can be fixedly connected to the base 20, and the first roller 20 can be adjustably connected to the base 10. In summary, as long as the distance between the first roller 20 and the second roller 30 can be adjusted, the specific connection form is not limited in the embodiment.

[0028] In a specific implementation, the base 10 can include a base plate 11, a second lead screw 12, a first base 13 and a second base 14. The first base 13 and the second base 14 are slidably connected to the base plate 11. In an example, the base plate 11 is provided with a sliding rail, and the first base 13 and the second base 14 are connected to the sliding blocks embedded in the sliding rail, respectively. The second lead screw 12 is arranged on the base plate 11, and the second lead screw 12 is sleeved with a first nut (not shown in the figure) and a second nut (not shown in the figure) that can move relative to or away from each other. The first base 13 is connected to the first nut, the second base 14 is connected to the second nut, the first roller 20 is arranged on the first base 13, and the second roller 30 is arranged on the second base 14.

[0029] When the second lead screw 12 is manually or electrically driven to rotate, the first base 13 and the second base 14 can be brought close to or away from each other, thereby driving the first roller 20 and the second roller 30 to approach or move away from each other, adjusting the distance between the first roller 20 and the second roller 30 to adapt to cylindrical barrels of different diameters.

[0030] The driving mechanism 40 is arranged on the base 10 and connected to the first roller 20 and the second roller 30, and is used for driving the first roller 20 and the second roller 30 to rotate. In particular, the driving mechanism 40 includes a first driving motor 41 and a second driving motor 42. The first driving motor 41 is connected to the first roller 20 and is used for driving the first roller 20 to rotate. The second driving motor 42 is connected to the second roller 30 and is used for driving the second roller 30 to rotate.

[0031] In an example, the first driving motor 41 and the second driving motor 42 can be variable frequency motors, and the first roller 20 and the second roller 30 can rotate in clockwise and counterclockwise directions. A variable frequency controller is used to control the first driving motor 41 and the second driving motor 42 simultaneously to realize synchronous driving.

[0032] The pressing mechanism 60 is movably connected to the stand 40 close to or away from the base 10, and is used for pressing the cylindrical barrel. In particular, the pressing mechanism 60 is used for pressing the side surface of the cylindrical barrel.

[0033] The stand 40 can be arranged at any position around the base 10, and can be connected with the base 10 or not, as long as the position between the pressing mechanism 60 and the first roller 20 and the second roller 30 is corresponding, so as to press the top of the cylindrical barrel (not shown in the figure) placed on the first roller 20 and the second roller 30.

[0034] In a specific implementation, the stand 40 can be a rectangular beam, a double-track type, etc. In order to ensure the strength and rigidity of the stand, the stand can also adopt a cold bending and welding structure.

[0035] In the embodiment of the application, the first roller 20 and the second roller 30 can be used for placing a cylindrical barrel with a length less than a diameter. The first roller 20 and the second roller 30 are driven to rotate by the driving mechanism 40, and then drive the cylindrical barrel to rotate. The pressing mechanism 60 is pressed on the top of the cylindrical barrel, which solves the problem that the cylindrical barrel with a length less than a diameter is easy to fall down, and ensures the stability of the cylindrical barrel during installation. In addition, it is also convenient for the operator to install, saves working hours, and improves production efficiency.

[0036] In some embodiments, continuing to refer to Figure 1 , the first roller 20 and the second roller 30 are both columnar rollers, and the axial length of the first roller 20 and the second roller 30 is greater than or equal to the axial length of the cylindrical barrel. When placing a cylindrical barrel with a length less than a diameter, the axes of the first roller 10, the second roller 30 and the cylindrical barrel can be arranged in parallel, so that the columnar roller and the cylindrical barrel have a larger contact area, and then the cylindrical barrel can rotate stably.

[0037] It can be understood that in some implementations, a control device 10a can also be included. The control device 10a is arranged on the stand 50. The control device 10a is connected with the pressing mechanism 60, and is used to control the pressing mechanism 60 to move along the stand 50. The control device 10a is also connected with the driving mechanism 40, and is used to control the driving mechanism 40 to rotate, and then drive the first roller 20 and the second roller 30 to rotate.

[0038] Continuing to refer to Figure 1 , in some embodiments, the pressing mechanism 60 includes a first connecting piece 61, a pressing roller 62 and a support frame 63. The first connecting piece 61 is movably connected to the stand 50 along the direction close to or away from the base 10.

[0039] In a specific implementation, the stand 50 is provided with a first lead screw 51, and the first connecting piece 61 is connected with the first lead screw 51 through a nut. The first lead screw 51 can be manually or electrically driven to rotate, and then drive the first connecting piece 61 to move through the nut.

[0040] The support frame 63 is connected to the first connecting member 61 , and the pressing roller 62 is connected to the support frame 63 and corresponds to the position between the first roller 20 and the second roller 30 to press the top of the cylindrical barrel placed on the first roller 20 and the second roller 30 .

[0041] Further, see Figure 1 In some embodiments, the invention further comprises: a connecting rod 64. The first connecting member 61 is provided with a connecting hole, the connecting rod 64 is passed through the connecting hole and is threadedly connected to the connecting hole, and one end of the connecting rod 64 ( Figure 1 The upper end shown) is formed with a handle 641, and the other end ( Figure 1 The lower end shown in FIG. 1 is connected to the support frame 63. By screwing the connecting rod 64 with the handle 641, the support frame 63 can be driven to drive the pressing roller 62 to move along the radial direction of the first roller 20 and the second roller 30.

[0042] When the cylindrical body is pressed, the first connecting frame 61 is first controlled downward (relative to the first connecting frame 61) by the first screw 51. Figure 1 When the pressure roller 62 and the cylindrical body are at a certain distance (for example, 1 mm), the first lead screw 51 stops rotating, and then the operating handle 641 is used for fine adjustment so that the pressure roller 62 is pressed against the top of the cylindrical body.

[0043] In one specific implementation, an elastic member, such as a spring, is sleeved on the exterior of the connecting rod 64. When the connecting rod 64 moves toward the cylindrical body, the elastic member compresses. When the elastic member compresses to a certain amount, it contacts a limit travel switch in the connecting hole. The limit travel switch then sends a travel signal to the control device, which records the fine-tuning movement of the connecting rod 64 and adjusts the travel of the first lead screw 51 accordingly. When a cylindrical body of the same diameter is crimped again, the control device incorporates the fine-tuning movement into the travel of the first lead screw 51, eliminating the need for fine-tuning via the connecting rod 64.

[0044] Furthermore, in some embodiments, the pressing roller 62 may be a cylindrical roller, and the axes of the pressing roller 62, the first roller 20, and the second roller 30 are arranged in parallel to increase the pressing area between the pressing roller 62 and the cylindrical barrel.

[0045] To locate the cylindrical body in the axial direction, see Figure 1 and Figure 3 In some embodiments, the first limiting mechanism 70 is further included. The first limiting mechanism 70 is connected to the base 10 and is placed on the first side of the axial direction of the first roller 20 and the second roller 30. Figure 1 The right side shown in the figure prevents the cylindrical barrel from axial movement during rotation.

[0046] In some embodiments, an axial limiting mechanism can also be included. The axial limiting mechanism is connected to the base 10 and is configured to limit the axial direction of the cylindrical barrel.

[0047] Further, in some embodiments, the axial limiting mechanism includes a first limiting mechanism 70 and a second limiting mechanism 80. The first limiting mechanism 70 and the second limiting mechanism 80 are both connected to the base 10 and are respectively arranged on the two sides of the axial direction of the cylindrical barrel, and are configured to limit the two sides of the axial direction of the cylindrical barrel.

[0048] Further, referring to Figure 3 In some embodiments, the first limiting mechanism 70 includes a first connecting assembly 71 and a first limiting roller 72.

[0049] The first connecting assembly 71 is adjustably connected to the base 10. In one specific implementation, one or more mounting holes are formed on the base 10 along the axial direction of the first roller 20 and the second roller 30. The first connecting assembly is connected to the base 10 through any of the mounting holes, for example, by screwing, etc., so as to adjust the position between the first connecting assembly 71 and the base 10.

[0050] The first limiting roller 72 is arranged on one end of the first connecting assembly 71 close to the first roller 20 and the second roller 30, so that the first limiting roller 72 can abut against the end of the cylindrical barrel.

[0051] It should be noted that the first limiting roller 72 in the present embodiment can be arranged corresponding to the axial line of the first roller 20 and the second roller 30, or can be arranged corresponding to any position in the region between the first roller 20 and the second roller 30, as long as it can contact the end surface of the cylindrical barrel to limit the first side of the axial direction of the cylindrical barrel.

[0052] In one specific implementation, the axial line of the first limiting roller 72 can be arranged perpendicular to the first roller 20 and the second roller 30. Since the axial lines of the cylindrical barrel, the first roller 20 and the second roller 30 can be arranged in parallel, the axial line of the first limiting roller 72 is arranged perpendicular to the axial line of the cylindrical barrel. When the cylindrical barrel rotates, the first limiting roller 72 can roll along the end surface of the cylindrical barrel, reducing friction and avoiding damage to the cylindrical barrel.

[0053] Further, referring to Figure 3In some embodiments, the first connecting assembly 71 may include: a sleeve 711, a slide rod 712, and a first locking member 713. The sleeve 711 is adjustably connected to the base 10, and the slide rod 712 is slidably sleeved on the sleeve 711. The sleeve 711 has a first connecting hole, and the slide rod 712 has at least one second connecting hole. The locking member 713 is inserted into the first connecting hole and any one of the second connecting holes. The first limiting roller 72 is installed at the protruding end of the slide rod 712 (for example, Figure 3 When the slide rod 712 has two or more second connection holes, the locking member 713 can be selectively passed through any one of the second connection holes to adjust the installation height of the first limiting roller 72 to accommodate cylindrical bodies of different diameters.

[0054] Alternatively, the slide rod 712 is provided with a first mounting hole, the sleeve 711 is provided with at least one second connection hole, and the locking member 713 is passed through the first mounting hole and any one of the second connection holes to lock the slide rod 712 and the sleeve 711 .

[0055] In this embodiment, the sleeve 711 is adjustable in position by bolts to the base 10. Specifically, the base 10 has one, two, or more connecting holes formed along the axial direction of the first roller 20 and the second roller 30. The sleeve 711 can be installed in any of the connecting holes to limit the position of cylindrical bodies of different lengths.

[0056] In some embodiments, the slide rod 712 may have a bending portion 712A, the bending portion 712a is arranged parallel to the axis of the cylindrical barrel, and the first limiting roller 72 is installed at the end of the bending portion 712a to fully contact the end of the cylindrical barrel.

[0057] In some embodiments, one first limiting mechanism 70 may be provided, or two or more may be provided. The specific number may be determined according to actual conditions and is not limited in this embodiment.

[0058] See also Figure 1 and Figure 2 In some embodiments, the second limiting mechanism 80 may include: a support body 81, a second connecting assembly 82, a second limiting roller 83, a cylinder 821b, and a telescopic rod 821c. The support body 81 is connected to the base 10, and the second connecting assembly 82 is adjustably connected to the support body 81 along the axial position of the first roller 20 and the second roller 30. The sleeve 821b is connected to the second connecting assembly 82, and the second limiting roller 83 is connected to the end of the telescopic rod 821c ( Figure 1 As shown in the upper end, the sleeve 821b is sleeved on the outside of the telescopic rod 821c, the second limiting roller 83 and the cylinder 821b have the same radial size, and the second limiting roller 83 and the cylinder 821b are used to abut against the end of the cylindrical cylinder.

[0059] The sleeve 821b is arranged at one end of the second connecting assembly 82 close to the first roller 20 and the second roller 30, the radial dimension of the sleeve 821b is the same as that of the second limiting roller 83, and the sleeve 821b and the second limiting roller 83 can simultaneously abut against the end surface of the cylindrical body to axially limit the cylindrical body.

[0060] In a specific implementation, the telescopic rod 821c and the sleeve 821b can be threadedly connected, and the second limiting roller 83 is fixedly connected (for example, welded, screwed, etc.) to the end of the telescopic rod 821c.

[0061] It should be noted that the second limiting roller 83 and the sleeve 821b in the embodiment can be arranged in correspondence with the axis of the first roller 20 and the second roller 30, or can be arranged at any position in the region between the first roller 20 and the second roller 30, as long as the second limiting roller 83 and the sleeve 821b can contact the end surface of the cylindrical body to limit the second side (the right side shown in FIG. 8) of the axis of the cylindrical body. Figure 1

[0062] In the embodiment, the mounting position of the second connecting assembly 82 and the support body 81 is adjusted to adjust the position of the second limiting roller 83 and the sleeve 821b, so as to limit the cylindrical bodies with different axial lengths. In addition, the telescopic rod 821c can be telescoped relative to the sleeve 821b to adjust the position of the second limiting roller 83 relative to the sleeve 821b, so as to abut against the end surface of the cylindrical body with different radial lengths.

[0063] Further, in some embodiments, the second connecting assembly 82 can include a second connecting piece 821 and a second locking piece 822. The support body 81 is provided with a first mounting hole, and the second connecting piece 821 is provided with a second mounting hole 821a, which is an oblong hole (as shown in FIG. 8B), and the length direction of the oblong hole is along the axis direction of the first roller 20 and the second roller 30. The second locking piece 822 is arranged in the first mounting hole and the second mounting hole to lock the support body 81 and the second connecting piece 821. Figure 2

[0064] The sleeve 821b is arranged at one end of the second connecting piece 821 close to the first roller 20 and the second roller 30. In one specific implementation, the sleeve 821b is connected to one end of the second connecting piece 821 close to the first roller 20 and the second roller 30, and the telescopic rod 821c is telescopically arranged in the sleeve 821b, and the telescopic rod 821c and the sleeve 821b can be threadedly connected. The second limiting roller 83 is fixedly arranged at the upper end of the telescopic rod 821c (relative to the second connecting piece 821). Figure 2 ​​In the shown state, the position of the second limiting roller 83 relative to the cylinder 821b can be adjusted in the radial direction of the first roller 20 and the second roller 30 when the telescopic rod 821c is telescopically moved relative to the cylinder 821b.

[0065] In the embodiment, the second mounting hole 821a is set as an oblong hole to adjust the mounting position of the second connecting piece 821 relative to the support body 81, and further adjust the position of the second limiting roller 83 and the cylinder 821b, so as to axially limit the cylindrical cylinder with different lengths.

[0066] Alternatively, the second connecting piece 82 is provided with a first mounting hole, the support body 81 is provided with a second mounting hole, and the fourth mounting hole is an oblong hole.

[0067] It can be seen that the first roller 20 and the second roller 30 can be used to place the cylindrical cylinder with a length less than a diameter. The first roller 20 and the second roller 30 are driven to rotate by the driving mechanism 40, and further drive the cylindrical cylinder to rotate. The compression mechanism 60 is compressed on the top of the cylindrical cylinder, which solves the problem that the cylindrical cylinder with a length less than a diameter is easy to fall down, and ensures the stability of the cylindrical cylinder during the installation process. In addition, it is also convenient for the operator to install, saves the working hours, and improves the production efficiency.

[0068] The above only describes the preferred embodiments of the present application and is not used to limit the present application.
