Description

Technical Field

[0001] The present application relates to the technical field of labeling machines, and in particular to a labeling machine capable of automatically loading and smoothing materials. Background Art

[0002] The labeling machine is a device that can stick rolled paper labels or metal foil labels on PCB, products or specified packaging. Its main structure includes a support platform, a labeling host installed on the support platform (used to drive the entire roll of labels and peel off individual labels to supply products. It consists of a stepper motor, a polyurethane label dividing wheel, a label output plate, a label guide shaft, a brake mechanism, a label measuring mechanism, a label stripping plate, a synchronous label receiving mechanism, a lifting mechanism and a front and rear adjustment mechanism.), a transport device installed on the support platform on the output side of the labeling host, and a transport device installed on the side of the transport device away from the labeling host and opposite to the output end. The method of using the limiting device of the labeling host is as follows: place the material to be labeled on the transport device. When the transport device transports it to between the output end of the limiting device and the output end of the labeling host, the limiting device is started, and its output end pushes the material to be attached to the output end of the labeling host. The output end of the labeling host rotates to drive the material to rotate and attach the label to the material at the same time (the output end of the limiting device is mainly composed of two vertical cylinders. Therefore, when the output end of the labeling host rotates, the limiting device will not limit the rotation of the material), and then the output end of the limiting device retracts, so that the transport device transports the material away and completes the attachment.

[0003] However, a problem often occurs in the prior art, that is, due to the unstable viscosity of the label, the two sides of the label will curl up after the label is attached to the material, causing the subsequent staff to have to press the label again, which is very inconvenient. Some technicians have proposed: setting multiple sets of limiting devices in the second half of the transportation device, so that the marks on the surface of the material are rolled by the cylinder of the limiting device for multiple times, thereby preventing the two sides of the label from curling up. However, setting multiple sets of limiting devices will result in the material needing to be limited multiple times during the entire transportation process, which greatly affects the efficiency of the transportation device in transporting materials and reduces the production efficiency of the labeling machine. For this reason, the present application proposes a labeling machine that can automatically load and smooth the material, which is used to make the label on the material stick tighter without affecting the efficiency of the transportation device in transporting materials. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of this application is to provide a labeling machine that can automatically load and smooth the materials, so that the labels on the materials are attached more tightly without affecting the efficiency of the transport device in transporting the materials.

[0005] The above-mentioned purpose of the present application is achieved through the following technical solutions: a labeling machine that can automatically load and smooth materials, including a supporting platform, a labeling main unit installed on the supporting platform, a transportation device installed on the supporting platform and located on the output end side of the labeling main unit, and a limiting device arranged on the side of the transportation device away from the labeling main unit and with the output end relative to the labeling main unit, the transportation device is arranged along the length direction of the supporting platform and exceeds the supporting platform, the transportation device is used to transport materials from the left side of the supporting platform to the right side of the supporting platform, and the front and rear sides of a section of the transportation device located on the right side of the labeling main unit are provided with a rolling structure for making the label on the material adhere more tightly without affecting the efficiency of the transportation device in transporting materials.

[0006] Furthermore, the rolling structure includes two fixed platforms and sliding platforms respectively arranged on both sides of the transport device and along the length direction of the transport device, a roller structure arranged on the sliding platform for rotating the material during movement, and an extrusion structure arranged on the fixed platform for extruding the material. The upper surfaces of the fixed platform and the sliding platform are provided with slide grooves arranged along their own width directions, and multiple slide grooves are provided along the length directions of the fixed platform and the sliding platform. The fixed platform and the sliding platform are provided with extrusion structures and roller structures in the same number as the number of slide grooves opened on them.

[0007] Furthermore, the roller structure includes a first sliding plate slidably connected to the sliding platform through a sliding groove, a positioning plate installed on the sliding platform on the side of the first sliding plate away from the transportation device, a pushing spring located between the first sliding plate and the positioning plate for pushing the first sliding plate toward the transportation device, a mounting plate arranged on the side of the first sliding plate close to the transportation device, two fixed plates respectively arranged at the upper and lower ends of the mounting plate, and a roller arranged between the two fixed plates and vertically rotatably connected to the fixed plates, and multiple rollers are arranged along the length direction of the fixed plates.

[0008] Furthermore, the extrusion structure includes a second sliding plate slidably connected to the fixed platform through a sliding groove, a limiting plate installed on the fixed platform on the side of the second sliding plate away from the transportation device, an extrusion spring located between the second sliding plate and the limiting plate for pushing the second sliding plate closer to the transportation device, and an extrusion plate arranged on the side of the second sliding plate close to the transportation device.

[0009] By adopting the above technical scheme, when the limiting device releases the limiting of the material, the material continues to be transported by the transport device. At this time, the material is transported by the transport device between the roller and the extrusion plate, and the material pushes the roller and the extrusion plate to compress the pushing spring and the extrusion spring. At the same time, during the transportation process, the circumference of the material contacts the circumference of the roller, and due to the effect of inertia, the material rotates together with the roller. During the rotation, the extrusion plate is pushed by the extrusion spring to extrude the circumference of the other side of the material, so that the material is close to the roller, so that the roller presses the label on the surface of the material, so that the label on the material is attached more tightly, and because the pushing spring and the extrusion spring are set, the roller and the extrusion plate have a certain elastic space, so that when the transport device transports the material, the material will not be stuck by the extrusion structure and the roller structure, thereby achieving the purpose of making the label on the material stick more tightly without affecting the efficiency of the transport device in transporting the material.

[0010] Furthermore, a first support rod is provided between the first sliding plate and the mounting plate, one end of the first support rod is fixedly connected to the mounting plate, and the other end is fixedly connected to the first sliding plate, and the mounting plate is mounted on the first sliding plate through the first support rod.

[0011] By adopting the above technical solution, the first support rod can make the bottom surface of the mounting plate extend directly above the transport device without contacting the sliding platform or the transport device, thereby preventing the bottom surface of the mounting plate from being damaged when the roller is pushed and squeezed by the material to push the spring.

[0012] Furthermore, a second support rod is provided between the extrusion plate and the second sliding plate, one end of the second support rod is fixedly connected to the extrusion plate, and the other end of the second support rod is fixedly connected to the second sliding plate, and the extrusion plate is mounted on the second sliding plate through the second support rod.

[0013] By adopting the above technical solution, the second support rod can allow the bottom surface of the extrusion plate to extend directly above the transport device without contacting the fixed platform or the transport device, thereby preventing the bottom surface of the extrusion plate from being damaged when the extrusion plate is pushed by the material to compress the extrusion spring.

[0014] Furthermore, the roller structure and the extrusion structure are respectively provided with a first control structure and a second control structure for controlling the distance between the roller structure and the extrusion structure on the side away from the transportation device, and the fixed platform and the sliding platform are both provided with limiting grooves arranged along their own width directions, and the limiting grooves are located on the side of the slide away from the transportation device and are colinear with the slide, the positioning plate is slidably installed on the sliding platform through the limiting grooves, and the limiting plate is slidably installed on the fixed platform through the limiting grooves.

[0015] Furthermore, the first control structure includes a U-shaped plate fixedly arranged on a side of the sliding platform away from the transport device, a connecting plate located between the U-shaped plate and the sliding platform, connecting rods arranged on the connecting plate in the same number as the roller structure, and a control threaded rod passing through the U-shaped plate from a side of the U-shaped plate away from the sliding platform and rotatably connected to the connecting plate, the control threaded rod being threadedly connected to the U-shaped plate, and a plurality of connecting rods being respectively connected to a side of the positioning plates of a plurality of roller structures away from the transport structure, and the other ends are all fixedly connected to the connecting plate, and the second control structure is the same as the first control structure, but the second control structure is arranged on a side of the extrusion structure away from the transport device.

[0016] By adopting the above technical solution, although the setting of the rolling structure makes the label on the material stick tighter without affecting the efficiency of the transport device in transporting materials, since the diameters of different batches of materials produced by the user are also different each time, if the distance between the roller structure and the extrusion structure is too large, the roller structure and the extrusion structure will not be able to effectively apply pressure to the material. If the distance between the roller structure and the extrusion structure is too small, the material will not be able to pass through. The setting of the first control structure and the second control structure solves this technical problem. When the user needs to process the next batch of materials, he only needs to turn the control threaded rod according to the size of the material. The control threaded rod pulls the connecting plate forward and backward. The connecting plate that moves forward and backward drives the roller structure and the extrusion structure to move through the connecting rod, thereby changing the distance between the roller structure and the extrusion structure to adapt to the new material size, thereby improving the applicability and practicality of the rolling structure.

[0017] Furthermore, the connecting rod includes a fixed rod and a plug-in rod, the fixed rod is arranged on a connecting plate, the plug-in rod is arranged on a roller structure or an extrusion structure, an end surface of the fixed rod away from the connecting plate is provided with a plug-in interface, the plug-in rod is plugged into the fixed rod through the plug-in interface, and a fixing structure for fixing the plug-in rod is provided at the joint between the plug-in rod and the fixed rod.

[0018] Furthermore, the fixing structure includes a positioning hole opened on the upper surface of the fixing rod and connected to the plug interface, a limiting hole opened on the upper surface of the plug rod and matched with the positioning hole, and a limiting rod extending through the positioning hole and into the limiting hole to fix the plug rod.

[0019] By adopting the above technical solution, although the setting of the first control structure and the second control structure improves the applicability and practicality of the rolling structure, it also causes the first control structure and the second control structure to connect multiple roller structures and extrusion structures in series, so that if a single roller structure is damaged, it is necessary to replace the entire first control structure and the roller structure connected thereto or the second control structure and the extrusion structure connected thereto, which is troublesome to replace and greatly increases the production cost. The setting of the fixed structure solves this technical problem. Through the setting of the fixed structure, when one of the multiple roller structures and the multiple extrusion structures is damaged, the user only needs to pull out the limit rod on the plug-in rod corresponding to the structure, and then slide the structure to make the plug-in rod detach from the fixed rod, so that the user can disassemble the structure for a separate replacement, which saves production costs and makes it more convenient for users to replace the roller structure or extrusion structure.

[0020] In summary, the present application includes at least one of the following beneficial technical effects: Through the setting of the rolling structure, when the limiting device releases the limit on the material, the material continues to be transported by the transportation device. At this time, the material is transported between the roller and the extrusion plate by the transportation device, and the material pushes the roller and the extrusion plate to compress the pushing spring and the extrusion spring. At the same time, during the transportation process, the circumference of the material contacts the circumference of the roller, and due to the effect of inertia, the material rotates together with the roller. During the rotation, the extrusion plate is pushed by the extrusion spring to extrude the circumference of the other side of the material, so that the material is close to the roller, so that the roller presses the label on the surface of the material, so that the label on the material is attached more tightly, and because the pushing spring and the extrusion spring are set, the roller and the extrusion plate have a certain elastic space, so that when the transportation device transports the material, the material will not be stuck by the extrusion structure and the roller structure, thereby achieving the purpose of making the label on the material stick more tightly without affecting the efficiency of the transportation device in transporting the material.

The transport device 11 is arranged along the length direction of the supporting platform 1 and exceeds the supporting platform 1. The transport device 11 is used to transport materials from the left side of the supporting platform 1 to the right side of the supporting platform 1. The front and rear sides of a section of the transport device 11 located on the right side of the labeling main machine 10 are provided with a rolling structure 3 for making the label on the material more tightly attached without affecting the efficiency of the transport device 11 in transporting the material. The rolling structure 3 comprises two blocks respectively provided with A fixed platform 30 and a sliding platform 31 are arranged on both sides of the transport device 11 and along the length direction of the transport device 11, a roller structure 32 is arranged on the sliding platform 31 for rotating the material during the movement, and an extrusion structure 33 is arranged on the fixed platform 30 for extruding the material. The upper surfaces of the fixed platform 30 and the sliding platform 31 are provided with a slide groove 34 arranged along their own width direction. A plurality of slide grooves 34 are provided along the length direction of the fixed platform 30 and the sliding platform 31. The fixed platform 30 and the sliding platform 31 are provided with an extrusion structure 33 and a roller structure 32 with the same number of slide grooves 34 as the number of the slide grooves 34 provided thereon. The roller structure 32 includes a first sliding plate 320 slidably connected to the sliding platform 31 through the slide groove 34, a position The first sliding plate 320 is provided with a positioning plate 321 mounted on the sliding platform 31 at a side of the first sliding plate 320 away from the transport device 11, a pushing spring 322 located between the first sliding plate 320 and the positioning plate 321 for pushing the first sliding plate 320 toward the transport device 11, a mounting plate 323 arranged on a side of the first sliding plate 320 close to the transport device 11, two fixing plates 324 respectively arranged at the upper and lower ends of the mounting plate 323, and a roller 325 arranged between the two fixing plates 324 and vertically connected to the fixing plates 324 for rotation, wherein the roller 325 is provided with a plurality of rollers along the length direction of the fixing plates 324, and the extrusion structure 33 includes a second sliding plate 330 slidably connected to the fixed platform 30 through a slide groove 34, and a second sliding plate 330 located away from the second sliding plate 330. The conveying device 11 has a limit plate 331 installed on the fixed platform 30 on one side, an extrusion spring 332 located between the second sliding plate 330 and the limit plate 331 for pushing the second sliding plate 330 toward the conveying device 11, and an extrusion plate 333 arranged on the second sliding plate 330 close to the conveying device 11. When the limit device 12 releases the limit on the material, the material continues to be transported by the conveying device 11. At this time, the material is transported by the conveying device 11 to between the roller 325 and the extrusion plate 333. The material pushes the roller 325 and the extrusion plate 333 to compress the push spring 322 and the extrusion spring 332. At the same time, during the transportation process, the circumference of the material contacts the circumference of the roller 325, and due to the effect of inertia, the material rotates together with the roller 325.During the rotation process, the squeezing plate 333 is pushed by the squeezing spring 332 to squeeze the circumference of the other side of the material, so that the material is close to the roller 325, so that the roller 325 presses the label on the surface of the material, so that the label on the material is attached more tightly, and because the setting of the pushing spring 322 and the squeezing spring 332 makes the roller 325 and the squeezing plate 333 have a certain elastic space, so that when the transport device 11 transports the material, the material will not be stuck by the squeezing structure 33 and the roller structure 32, thereby achieving the purpose of making the label on the material more tightly attached without affecting the efficiency of the transport device 11 in transporting the material.

[0025] In this embodiment, a first support rod 326 is provided between the first sliding plate 320 and the mounting plate 323. One end of the first support rod 326 is fixedly connected to the mounting plate 323, and the other end is fixedly connected to the first sliding plate 320. The mounting plate 323 is installed on the first sliding plate 320 through the first support rod 326. The first support rod 326 enables the bottom surface of the mounting plate 323 to extend directly above the transport device 11 without contacting the sliding platform 31 or the transport device 11, thereby preventing the bottom surface of the mounting plate 323 from being damaged when the roller 325 is pushed by the material to squeeze the push spring 322.

[0026] In this embodiment, a second support rod 334 is provided between the extrusion plate 333 and the second sliding plate 330. One end of the second support rod 334 is fixedly connected to the extrusion plate 333, and the other end is fixedly connected to the second sliding plate 330. The extrusion plate 333 is installed on the second sliding plate 330 through the second support rod 334. The second support rod 334 enables the bottom surface of the extrusion plate 333 to extend directly above the transport device 11 without contacting the fixed platform 30 or the transport device 11, thereby preventing the bottom surface of the extrusion plate 333 from being damaged when the extrusion plate 333 is pushed by the material to compress the extrusion spring 332.

[0027] Although the setting of the rolling structure 3 makes the label on the material stick more tightly without affecting the efficiency of the transport device 11 in transporting the material, since the diameters of different batches of materials produced by the user are also different each time, if the distance between the roller structure 32 and the extrusion structure 33 is too large, the roller structure 32 and the extrusion structure 33 will not be able to effectively apply pressure to the material. If the distance between the roller structure 32 and the extrusion structure 33 is too small, the material will not be able to pass. In order to solve this technical problem, in this embodiment, the roller structure 32 and the extrusion structure 33 are far away from the transport device 11. The first control structure 4 and the second control structure 5 for controlling the distance between the roller structure 32 and the extrusion structure 33 are respectively provided on one side of the device 11. The fixed platform 30 and the sliding platform 31 are both provided with a limit groove 35 arranged along their own width direction. The limit groove 35 is located on the side of the slide 34 away from the transport device 11 and is in line with the slide 34. The positioning plate 321 is slidably installed on the sliding platform 31 through the limit groove 35. The limit plate 331 is slidably installed on the fixed platform 30 through the limit groove 35. The first control structure 4 includes a fixedly arranged on the sliding platform 31. The U-shaped plate 40 on the side away from the transport device 11, the connecting plate 41 located between the U-shaped plate 40 and the sliding platform 31, the connecting rods 42 arranged on the connecting plate 41 and the same number as the roller structures 32, and the control threaded rod 43 passing through the U-shaped plate 40 from the side away from the sliding platform 31 and rotatably connected to the connecting plate 41, the control threaded rod 43 is threadedly connected to the U-shaped plate 40, and the plurality of connecting rods 42 are respectively connected to the sides of the positioning plates 321 of the plurality of roller structures 32 away from the transport structure, and the other ends are fixedly connected to the connecting plate 41, and the second control The control structure 5 is the same as the first control structure 4, but the second control structure 5 is arranged on the side of the extrusion structure 33 away from the transportation device 11. When the user needs to process the next batch of materials, he only needs to turn the control threaded rod 43 according to the size of the material. The control threaded rod 43 pulls the connecting plate 41 to move forward and backward. The connecting plate 41 that moves forward and backward drives the roller structure 32 and the extrusion structure 33 to move through the connecting rod 42, thereby changing the distance between the roller structure 32 and the extrusion structure 33 to adapt to the new size of the material, thereby improving the applicability and practicality of the rolling structure 3.

[0028] Although the arrangement of the first control structure 4 and the second control structure 5 improves the applicability and practicality of the rolling structure 3, it also causes the first control structure 4 and the second control structure 5 to connect multiple roller structures 32 and extrusion structures 33 in series, so that if a single roller structure 32 is damaged, it is necessary to replace the entire first control structure 4 and the roller structure 32 connected thereto or the second control structure 5 and the extrusion structure 33 connected thereto. The replacement is troublesome and greatly increases the production cost. In order to solve this technical problem, the present embodiment arranges the connecting rod 42 to include a fixed rod 420 and a plug-in rod 421, the fixed rod 420 is arranged on the connecting plate 41, the plug-in rod 421 is arranged on the roller structure 32 or the extrusion structure 33, and the end face of the fixed rod 420 away from the connecting plate 41 is provided with a plug-in interface, and the plug-in rod 421 is connected to the roller structure 32 or the extrusion structure 33 by plugging The port is plugged into the fixing rod 420, and a fixing structure 6 for fixing the plug-in rod 421 is provided at the connection between the plug-in rod 421 and the fixing rod 420. The fixing structure 6 includes a positioning port 60 opened on the upper surface of the fixing rod 420 and connected to the plug-in port, a limiting port opened on the upper surface of the plug-in rod 421 and matched with the positioning port 60, and a limiting rod 61 passing through the positioning port 60 and extending into the limiting port to fix the plug-in rod 421. When one of the multiple roller structures 32 and the multiple extrusion structures 33 is damaged, the user only needs to pull out the limiting rod 61 on the plug-in rod 421 corresponding to the structure, and then slide the structure to make the plug-in rod 421 detach from the fixing rod 420, so that the user can disassemble the structure for separate replacement, which saves production costs and makes it more convenient for the user to replace the roller structure 32 or the extrusion structure 33.

[0029] Specific implementation process: Place the material to be labeled on the transport device 11, start the transport device 11 and the labeling host 10, when the transport device 11 transports the material to between the output end of the limiting device 12 and the output end of the labeling host 10, the limiting device 12 is started, and its output end pushes the material to attach to the output end of the labeling host 10, the output end of the labeling host 10 rotates to drive the material to rotate and attach the label to the material, then the output end of the limiting device 12 retracts, so that the transport device 11 transports the material, and then the transport device 11 transports the material to between the roller 325 and the extrusion plate 333, the material pushes the roller 325 and the extrusion plate 333 to compress the push spring 322 and The extrusion spring 332, during the transportation process, the circumference of the material contacts the circumference of the roller 325, and due to the effect of inertia, the material rotates together with the roller 325. During the rotation, the extrusion plate 333 is pushed by the extrusion spring 332 to extrude the circumference of the other side of the material, so that the material is close to the roller 325, so that the roller 325 presses the label on the surface of the material, making the label on the material stick tighter. In addition, due to the setting of the pushing spring 322 and the extrusion spring 332, the roller 325 and the extrusion plate 333 have a certain elastic space, so that the material will not be stuck by the extrusion structure 33 and the roller structure 32 when the transportation device 11 transports the material.

[0030] When the user needs to change the distance between the roller structure 32 and the extrusion structure 33, he only needs to turn the control threaded rod 43 according to the size of the material. The control threaded rod 43 pulls the connecting plate 41 forward and backward, and the connecting plate 41 that moves forward and backward drives the roller structure 32 and the extrusion structure 33 to move through the connecting rod 42, thereby changing the distance between the roller structure 32 and the extrusion structure 33 to adapt to the new size of the material.

[0031] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application.
