Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a rotary tube labeling machine. Background Technology

[0002] Hose products refer to packaging products made of flexible materials with a hollow tubular structure, mainly used to store fluid or semi-fluid substances. The contents can be discharged by squeezing the tube body during use. Hose labeling refers to the process of accurately affixing labels such as product information labels and anti-counterfeiting labels to the surface of hose packaging products.

[0003] Traditional tube labeling is done manually. However, manual labeling is inefficient and relies on visual judgment of label alignment and the operator's skill level, leading to inconsistent labeling accuracy and quality. Automatic labeling machines for tubes have emerged on the market. These machines move the loaded tube to the labeling station in front of the peeling plate. The peeled label first contacts the tube surface, and then the application roller rolls at a set pressure from the initial contact end to the other, completely pressing the label onto the tube. However, different tubes have different shapes, such as cylindrical and tapered. Cylindrical tubes have straight sides, while tapered tubes have sloping sides, resulting in different labeling angles. Some existing labeling machines cannot adjust the labeling angle for different tube shapes, limiting their applicability. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a rotary tube labeling machine with high labeling efficiency, labeling accuracy and stable labeling quality, and the ability to adjust the labeling angle for tube products of different shapes.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A rotary tube labeling machine includes a frame with a worktable on top. A rotary assembly, a label application assembly, a label conveying assembly, and a label peeling assembly are mounted on the worktable. The rotary assembly includes a rotary table and a rotary drive device. The axis of the rotary table is parallel to the worktable. Multiple stations are equidistantly spaced along the circumference of the rotary table. Each station is rotatably connected to a tube support cylinder for supporting the tube product. The rotary drive device drives the rotary table to rotate intermittently clockwise. The label application assembly includes a label angle adjustment bracket and a label application mechanism. The label angle adjustment bracket includes a positioning bracket, two side plates, and an angle adjustment pad. The positioning bracket is vertically positioned behind the rotary table. The two side plates are fixedly connected to the top sides of the positioning bracket. Each side plate has a first connecting through hole and a first arc-shaped through hole. The center of the first arc-shaped through hole is connected to the first connecting through hole. The centers of the holes coincide. The angle adjustment pad has a first screw hole and a second screw hole at both ends that match the first connecting through hole and the first arc-shaped through hole, respectively. The labeling mechanism is installed on the angle adjustment pad and located above the turntable. It is used to further compact the label initially pasted on the surface of the hose product at the labeling station. The label tape conveying assembly is located on one side of the turntable assembly. The label tape conveying assembly has a second connecting through hole and a second arc-shaped through hole. The center of the second arc-shaped through hole coincides with the center of the second connecting through hole. The label peeling assembly includes a label peeling angle adjustment block and a label peeling plate. The label peeling angle adjustment block has a third screw hole and a fourth screw hole that match the second connecting through hole and the second arc-shaped through hole, respectively. The label peeling plate is installed on the label peeling angle adjustment block and extends above the hose product at the labeling station. It is used to peel the label off the backing paper.

[0007] In some embodiments, the label tape conveying assembly includes an orientation adjustment bracket and a label tape conveying mechanism. The orientation adjustment bracket is mounted on a worktable, and the label tape conveying mechanism is mounted on the orientation adjustment bracket and located on one side above the turntable.

[0008] Compared with the prior art, this utility model achieves at least the following beneficial effects:

[0009] (1) This utility model can realize automatic labeling of hose products with high labeling efficiency, labeling accuracy and stable quality. First, the hose product is manually attached to the hose support cylinder of the turntable loading station. The turntable drive device drives the turntable to rotate clockwise intermittently. When the hose product rotates to the labeling station, the label tape conveying mechanism, the label covering mechanism and other components work. The label tape conveying mechanism conveys the label tape to the labeling station. When the back paper of the label tape passes around the edge of the peeling plate, the label separates from the back paper due to inertia. The separated label first contacts the surface of the hose. Then the label covering mechanism presses the label completely onto the hose. Finally, the turntable rotates the finished labeled hose to the unloading station for unloading.

[0010] (2) When in use, this utility model can change the angle of the angle adjustment pad to make it tilt, and the labeling mechanism will tilt accordingly. When the labeling hose product is a conical tube, the tilt angle of the labeling mechanism can be adjusted to match the tilted side of the conical tube. It can also change the angle of the peeling angle adjustment block to make it tilt, and the peeling plate will tilt accordingly, so that the angle of the separated label matches the tilted side of the conical tube. It has good applicability. Attached Figure Description

"Below," "below," and "under" of a second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0021] like Figures 1-7 As shown in the embodiment of this application, the rotary tube labeling machine includes a frame 1, a worktable 11 on the top of the frame 1, and a rotary assembly 2, a labeling assembly 3, a label tape conveying assembly 4 and a label peeling assembly 5 installed on the worktable 11.

[0022] The turntable assembly 2 includes a turntable 21 and a turntable drive device 22. The axis of the turntable 21 is parallel to the worktable 11. Multiple workstations are equidistantly spaced along the circumference of the turntable 21, including a loading workstation 211, a labeling workstation 212, and a unloading workstation 213. Each workstation is rotatably connected to a hose support cylinder 6 for supporting the hose product 30. The turntable drive device 22 is used to drive the turntable 21 to rotate clockwise intermittently.

[0023] Specifically, the turntable drive device 22 is a cam divider, and a central shaft 7 is vertically fixedly connected to the turntable 21. The central shaft 7 is connected to the output shaft of the turntable drive device 22.

[0024] The labeling assembly 3 includes a labeling angle adjustment bracket 31 and a labeling mechanism 32. The labeling angle adjustment bracket 31 includes a positioning bracket 311, two side plates 312, and an angle adjustment pad 313. The positioning bracket 311 is erected behind the turntable 21. The two side plates 312 are respectively fixedly connected to the top two sides of the positioning bracket 311. Each of the two side plates 312 is provided with a first connecting through hole 312a and a first arc-shaped through hole 312b. In this embodiment, the first connecting through hole 312a is located at the front position on the side plate 312, and the first arc-shaped through hole 312b is located on the side plate 312. The first arc-shaped through hole 312b is positioned at the rear of the first arc-shaped through hole 312b, and the center of the first arc-shaped through hole 312a coincides with the center of the first connecting through hole 312a. The two ends of the angle adjusting pad 313 are provided with a first screw hole 313a and a second screw hole 313b that match the first connecting through hole 312a and the first arc-shaped through hole 312b, respectively. A first screw (not shown in the figure) is inserted through the first connecting through hole 312a and threaded to the first screw hole 313a. A second screw (not shown in the figure) is inserted through the first arc-shaped through hole 312b and threaded to the second screw hole 313b. The labeling angle adjustment bracket 31 is used to adjust the angle of the labeling mechanism 32. When the first screw and the second screw at both ends of the angle adjustment pad 313 are loosened, the angle adjustment pad 313 and the first screw can rotate around the axis of the first connecting through hole 312a, while the movement trajectory of the second screw is an arc. The second screw can move along the first arc-shaped through hole 312b, thereby changing the angle of the angle adjustment pad 313 and causing it to tilt. The labeling mechanism 32 is installed on the angle adjustment pad 313 and is located above the turntable 21. Therefore, when the angle adjustment pad 313 tilts, the labeling mechanism 32 tilts accordingly. When the hose product 30 to be labeled is a tapered tube, the tilt angle of the labeling mechanism 32 is adjusted to match the tilted side of the tapered tube. When the labeling mechanism 32 is working, it further compacts and smooths the label initially pasted on the surface of the hose product 30 at the labeling station 212, ensuring that the label is tightly attached to the surface of the hose product 30.

[0025] Specifically, the labeling mechanism 32 includes a cylinder mounting plate 321, a labeling cylinder 322, a roller bracket 323, a labeling and coating roller 324, and a labeling motor. The cylinder mounting plate 321 is fixed on the angle adjustment pad 313 and extends forward. The labeling cylinder 322 is fixed vertically downward on the cylinder mounting plate 321. The roller bracket 323 is fixed at the output end of the labeling cylinder 322. A spindle 324a is fixed at the center of the labeling and coating roller 324. The two ends of the spindle 324a are rotatably connected to the roller bracket 323. The labeling motor is used to drive the spindle 324a and the labeling and coating roller 324 to rotate. The rotation of the labeling and coating roller 324 further compacts and smooths the label on the surface of the hose product 30.

[0026] The label tape conveying assembly 4 is located on one side of the turntable assembly 2. The label tape conveying assembly 4 is used to convey the label tape to the labeling station 212. The label tape conveying assembly 4 is provided with a second connecting through hole 421 and a second arc-shaped through hole 422. In this embodiment, the second arc-shaped through hole 422 is located at the lower left edge of the label tape conveying assembly 4, and the second connecting through hole 421 is located to the right of the second arc-shaped through hole 422. The center of the second arc-shaped through hole 422 coincides with the center of the second connecting through hole 421. The label peeling assembly 5 includes a label peeling angle adjusting block 51 and a label peeling plate 52. The label peeling angle adjusting block 51 is provided with a third screw hole 511 and a fourth screw hole 512 that match the second connecting through hole 421 and the second arc-shaped through hole 422, respectively. The label peeling plate 52 is installed on the label peeling angle adjusting block 51 and extends above the hose product 30 of the labeling station 212. It is used to peel the label off from the backing paper. A third screw (not shown in the figure) is inserted through the second connecting through hole 421 and threaded into the third screw hole 511. A fourth screw (not shown in the figure) is inserted through the second arc-shaped through hole 422 and threaded into the fourth screw hole 512. The label peeling angle adjusting block 51 is used to adjust the angle of the label peeling plate 52. When the third and fourth screws of the label peeling angle adjusting block 51 are loosened, the label peeling angle adjusting block 51 and the third screw can rotate around the axis of the second connecting through hole 421, while the movement trajectory of the fourth screw is an arc. The fourth screw can move along the second arc-shaped through hole 422. The hole 422 moves, thereby changing the angle of the peeling angle adjustment block 51 and the peeling plate 52, causing the peeling plate 52 to tilt. The peeling plate 52, through its sharp edge and specific angle design, makes a sharp turn when the backing paper of the label tape passes around the edge of the peeling plate 52. The label separates from the backing paper due to inertia and is individually conveyed to the hose product 30 of the labeling station 212. The separated label first contacts the surface of the hose, and then the labeling and coating roller 324 of the labeling mechanism 32 rolls from the initial contact end of the label to the other end with a set pressure, so that the label can be completely pressed onto the hose.

[0027] Specifically, the label tape conveying assembly 4 includes an orientation adjustment bracket 41 and a label tape conveying mechanism 42. The orientation adjustment bracket 41 is mounted on the workbench 11, and the label tape conveying mechanism 42 is mounted on the orientation adjustment bracket 41 and located above the turntable 21. The orientation adjustment bracket 41 is used to adjust the orientation of the label tape conveying mechanism 42 on the workbench 11, and can also indirectly adjust the orientation of the label peeling assembly 5 to adapt it to the shape of the flexible tube product 30. It should be noted that the structure of the label tape conveying mechanism 42 is well known. For example, Chinese patent document CN216103192U discloses a turntable labeling machine, whose label tape conveying mechanism 42 consists of a mounting plate, a material tray, a tension roller, a conveying motor, etc. The label tape roll is mounted on the material tray, and the label tape is wound onto the tension roller and other roller components in a specified order. This application does not limit the structure of the label tape conveying mechanism 42, as long as it can realize the conveying of the label tape.

[0028] Furthermore, the orientation adjustment bracket 41 includes a left-right displacement adjustment bracket 4110, a right-down displacement adjustment bracket 4120, and a front-back displacement adjustment bracket 4130; the left-right displacement adjustment bracket 4110 includes a first bracket 4111, an X-axis slide rod 4112, an X-axis lead screw and nut pair 4113, a first adjustment handwheel 4114, and an X-axis slide block 4115. The first bracket 4111 is fixed on the worktable 11, the X-axis slide rod 4112 is fixed on the first bracket 4111, and the X-axis lead screw and nut pair 4113... The rod is rotatably connected to the first bracket 4111. The first adjusting handwheel 4114 is located at the outer end of the X-axis lead screw nut pair 4113. The X-axis slide 4115 is slidably connected to the X-axis slide rod 4112 and fixedly connected to the nut of the X-axis lead screw nut pair 4113. The vertical displacement adjusting bracket 4120 includes a second bracket 4121, a Z-axis slide rod 4122, a Z-axis lead screw nut pair 4123, a second adjusting handwheel 4124, and a Z-axis slide 4125. The second bracket 4121 is fixed on the X-axis slide 4115. The Z-axis slide bar 4122 is fixed on the second bracket 4121. The lead screw of the Z-axis lead screw nut pair 4123 is rotatably connected to the second bracket 4121. The second adjusting handwheel 4124 is located at the outer end of the Z-axis lead screw nut pair 4123. The Z-axis slide block 4125 is slidably connected to the Z-axis slide bar 4122 and fixedly connected to the nut of the Z-axis lead screw nut pair 4123. The front and rear displacement adjusting bracket 4130 includes a third bracket 4131, a Y-axis slide bar 4132, a Y-axis lead screw nut pair 4133, and a third adjusting handwheel. Wheel 4134 and Y-axis slide 4135, third bracket 4131 is fixed on Z-axis slide 4125, Y-axis is fixed on third bracket 4131, Y-axis lead screw nut pair 4133 is rotatably connected to third bracket 4131, third adjusting handwheel 4134 is located at the outer end of Y-axis lead screw nut pair 4133, Y-axis slide 4135 is slidably connected to Y-axis slide rod 4132 and fixedly connected to nut of Y-axis lead screw nut pair 4133; label tape conveying assembly 4 is installed on Y-axis slide 4135. By rotating the lead screw of the X-axis lead screw and nut pair 4113 using the first adjusting handwheel 4114, the rotational motion of the lead screw is converted into the linear motion of the nut, thereby driving the X-axis slide 4115 and the vertical displacement adjusting bracket 4120 on the X-axis slide 4115 to move left and right, adjusting the left and right positions. Similarly, the vertical position of the Z-axis slide 4125 and the front and rear displacement adjusting bracket 4130 can be adjusted by the second adjusting handwheel 4124, and the front and rear position of the Y-axis slide 4135 and the label tape conveying mechanism 42 can be adjusted by the third adjusting handwheel 4134.

[0029] Optionally, the front end of the hose support cylinder 6 is set as a tapered body that matches the shape of the hose product 30, and the side wall of the hose support cylinder 6 is provided with an annular positioning shoulder 61. The hose product 30 is sleeved on the front end of the hose support cylinder 6, and the hose support cylinder 6 can adapt to the tapered tube body. The annular positioning shoulder 61 is used to limit the hose product 30.

[0030] In this embodiment, a clamping assembly 8 is also installed on the workbench 11. The clamping assembly 8 is located in front of the turntable 21. The clamping assembly 8 includes an aluminum profile support frame 81 and a clamping cylinder 82. An optical fiber sensor 83 is installed on the aluminum profile support frame 81 below the hose support cylinder 6 at the labeling station 212. The optical fiber sensor 83 is used to detect whether the hose product 30 is in place. It is used to transmit the in-place signal to the control system of the labeling machine. The control system can control the operation of components such as the clamping cylinder 82, the labeling mechanism 32, and the label tape conveying mechanism 42. The clamping cylinder 82 is installed on the aluminum profile support frame 81. Its output end faces the hose product 30 at the labeling station 212 and is equipped with a cam bearing follower 821. A top block 822 is installed on the outer ring of the cam bearing follower 821. The top block 822 is used to clamp the hose product 30 onto the hose support cylinder 6.

[0031] In this embodiment, the workbench 11 is also equipped with a feeding chute 9 and an air blowing assembly 10. The feeding chute 9 is located in front of the turntable 21, and the side wall of the feeding chute 9 is provided with an inlet hole that matches the hose product 30 of the feeding station 213. The air blowing assembly 10 is located behind the turntable 21. It is used to blow the hose product 30 of the feeding station 213 from the hose support cylinder 6 into the feeding chute 9. The air blowing assembly 10 includes a pneumatic connector 101 and an air nozzle 102. The air nozzle 102 is connected to one end of the pneumatic connector 101, and the air nozzle 102 is aligned with the rear opening of the hose support cylinder 6 of the feeding station 213. The other end of the pneumatic connector 101 is connected to an external air compressor through a pipe.

[0032] In this embodiment, the workbench 11 is also equipped with a control panel 20.

[0033] The working process of this utility model is as follows:

[0034] First, the hose product 30 is manually fitted onto the hose support cylinder 6 of the loading station 211 of the turntable 21. The turntable drive device 22 drives the turntable 21 to rotate clockwise intermittently. Then, when the fiber optic sensor 83 detects that the hose product 30 has rotated to the labeling station 212, the label tape conveying mechanism 42, the labeling mechanism 32, the clamping component 8 and other components work. The label tape conveying mechanism 42 conveys the label tape to the labeling station 212. When the backing paper of the label tape passes around the edge of the peeling plate 52, it makes a sharp turn. Due to inertia, the label separates from the backing paper and is conveyed separately to the hose product 30 at the labeling station 212. The separated label first contacts the surface of the hose, and then the labeling and coating roller 324 of the labeling mechanism 32 rolls from the initial contact end of the label to the other end, which can automatically press the label completely onto the hose. Finally, the turntable 21 rotates the finished labeled hose to the unloading station 213 for unloading. In use, this utility model can change the angle of the angle adjustment pad 313 to make it tilt, and the labeling mechanism 32 will tilt accordingly. When the labeling hose product 30 is a conical tube, the tilt angle of the labeling mechanism 32 can be adjusted to match the tilted side of the conical tube. It can also change the angle of the peeling angle adjustment block 51 to make it tilt, and the peeling plate 52 will tilt accordingly, so that the angle of the separated label matches the tilted side of the conical tube.

[0035] It should be understood that all the above embodiments are exemplary and not restrictive. Any modifications, equivalent changes and alterations made by those skilled in the art to the specific embodiments described above under the concept of this utility model shall still fall within the scope of the technical solution of this utility model.
