Description

Technical Field

[0001] This application relates to the field of heat transfer equipment, and more particularly to a multi-station roll cutting and labeling machine. Background Technology

[0002] Thermal transfer printing is a printing process. Its core principle is to use heat energy to precisely transfer patterns pre-printed on a heat-resistant substrate film (transfer film) onto the surface of the target product through high temperature and high pressure. It has a wide range of applications and significant technical advantages.

[0003] In the manufacturing process of footwear and apparel, small trademark logos are often printed using heat transfer printing. Chinese patent application CN114084722A discloses an automatic labeling machine, including a frame with a heat-pressing mechanism, a feeding base, and a cutting and transferring mechanism. The feeding base guides and supports the transfer film, while the cutting and transferring mechanism transfers the film at the end of the feeding base. Based on this, by placing the heat transfer carrier on the heat-pressing mechanism, the cutting and transferring mechanism can transfer the cut transfer film onto the carrier, and the heat-pressing mechanism performs a stamping heat transfer between the transfer film and the carrier, resulting in a high degree of automation.

[0004] Regarding the aforementioned technical solutions, although the automatic labeling machine can automatically complete the cutting and transfer of the transfer film, the heat transfer carrier still needs to be manually placed under the working area of ​​the heat pressing mechanism. The manual operation method is unsafe. Although the equipment is equipped with corresponding sensors and foolproof mechanisms to reduce the risk of accidental hand crushing by the heat pressing mechanism, there are still situations where the sensors are not sensitive enough, causing the foolproof mechanism to fail to function, thus still posing certain safety hazards and requiring improvement. Utility Model Content

[0005] Based on this, this application provides a multi-station roll cutting and labeling machine. By separating the feeding station and the hot pressing station, the possibility of accidental hand pressing by the hot pressing mechanism can be greatly reduced, thereby improving the safety factor.

[0006] The multi-station roll cutting and labeling machine provided in this application adopts the following technical solution:

[0008] Rack assembly;

[0009] A rotating mechanism is rotatably mounted on the frame assembly and is connected to a drive structure.

[0010] The stage mechanism is located on the rotating mechanism. The stage mechanism is equipped with multiple negative pressure mold seats, each of which is circumferentially linked to the stage mechanism. The negative pressure mold seats are used to position the heat transfer carrier and make it rotate with the stage mechanism. All negative pressure mold seats are connected to a negative pressure generator.

[0011] The cutting and transfer mechanism is located on the frame assembly and is situated on the rotation path of the negative pressure mold base.

[0012] The hot pressing mechanism is located on the frame assembly, on the rotation path of the negative pressure mold base and at the rear end of the cutting and transfer mechanism.

[0013] Optionally, the stage mechanism includes:

[0014] The platform base is fixedly connected to the rotating mechanism, and each negative pressure mold base is evenly distributed on the platform base.

[0015] The workstation plate is fixed to the top of the platform base. The workstation plate has workstation slots for each negative pressure mold base to pass through. There is a receiving space between the workstation plate and the platform base for fixing the negative pressure mold base.

[0016] The space contains a manifold mold base, and each negative pressure mold base is connected to the manifold mold base. The manifold mold base is connected to the negative pressure generator through a pipeline mechanism to maintain the negative pressure of the negative pressure mold base when the platform mechanism rotates.

[0017] Optional, the piping system includes:

[0018] The connector is fixedly mounted inside the frame assembly; the connector is equipped with an air passage interface for connecting to the negative pressure generator;

[0019] The connector assembly is located between the connector seat and the manifold seat. The top end of the connector assembly is connected to the inside of the manifold seat, and the bottom end of the connector assembly is connected to the inside of the connector seat.

[0020] Optionally, the takeover components include:

[0021] The first pipe section is matched and installed inside the connector seat. The connector seat is equipped with a return spring, which is normally pressed against the first pipe section.

[0022] The second pipe section is located above and abuts against the first pipe section; the second pipe section is rotatably connected to the inner wall of the joint seat via a bearing;

[0023] The third pipe section is fixedly connected to the bottom of the manifold base. The third pipe section is located above the second pipe section and is tightly inserted and fitted with the second pipe section through a return spring.

[0024] Optionally, a connecting component is provided on the outer periphery of the connector seat, and two shaft members are vertically arranged on the inner side of the frame assembly. The connector seat can be detachably fixed between the two shaft members through the connecting component.

[0025] Optionally, the frame assembly is provided with multiple sets of support units on the side near the platform mechanism, and all support units are evenly distributed around the rotation axis of the rotating mechanism; wherein, the support unit includes a fixed support column and a rolling component rotatably connected to the fixed support column, and the platform mechanism normally rests against the rolling component.

[0026] Optionally, the support unit located below the hot pressing mechanism is set as the main load-bearing unit. The main load-bearing unit includes multiple fixed supports, all of which are evenly distributed around the center of the hot pressing mechanism. Each fixed support is rotatably connected to a rolling component.

[0027] Optionally, there are at least four sets of negative pressure mold bases, and the positions of each negative pressure mold base are set as loading station, labeling station, hot pressing station and unloading station in sequence.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. When the operator is performing the operation, by placing the heat transfer carrier at the loading station and having it attracted by the negative pressure mold base, the rotation mechanism can be controlled to rotate the platform mechanism. The heat transfer carrier moves sequentially to the label station, the hot pressing station, and the unloading station, which can automatically complete the two processes of label placement and hot pressing transfer. The operator can easily take out the transferred finished product at the unloading station, making the operation convenient. By separating the loading station and the hot pressing station, the possibility of accidental hand crushing by the hot pressing mechanism is greatly reduced, improving the safety factor.

[0030] 2. When the negative pressure generator of this application is working, the air inside each negative pressure mold base can be drawn into the manifold mold base and extracted by the negative pressure generator along the pipeline mechanism and connector seat, so that negative pressure can be formed inside each negative pressure mold base. Then, when the heat transfer carrier is placed in the negative pressure mold base, it can be stably adsorbed, so that the rotating mechanism can smoothly drive the heat transfer carrier to move when it rotates, and the heat transfer carrier can smoothly enter the label station and the hot pressing station.

[0031] 3. The pipeline structure of this application consists of a first pipe section, a second pipe section and a third pipe section, and the connector seat is detachably fixed between two shaft members by connecting components. By removing the connecting components, the connector seat and each pipe section can be easily separated and removed, which helps to quickly disassemble and clean the connector seat and pipeline structure, and reduces the possibility that the accumulation of dust inside the connector seat and pipeline structure will affect the adsorption effect.

[0032] 4. This application provides support for the platform mechanism by setting up multiple sets of support units, which helps the platform mechanism maintain good stability when rotating. Furthermore, it can enhance the load-bearing capacity of the platform mechanism when the hot pressing mechanism performs heat transfer on the carrier, and reduce the possibility of the platform mechanism being deformed or displaced under pressure.

[0043] The following is in conjunction with the appendix Figure 1-6This application will be described in further detail.

[0044] This application discloses a multi-station roll cutting and labeling machine.

[0045] Reference Figure 1 , Figure 2 A multi-station roll cutting and labeling machine includes a frame assembly 1, a rotating mechanism 2, a platform mechanism 3, a cutting and transferring mechanism 4, and a hot pressing mechanism 5. The rotating mechanism 2 is rotatably mounted on the frame assembly 1 and is connected to a drive structure 23 to drive its rotation. Specifically, the rotating mechanism 2 includes a base 21 and a rotating seat 22 rotatably mounted inside the base 21. The rotating seat 22 can rotate circumferentially around its central axis. The drive structure 23 is a servo motor, fixed to the base 21, and its output is connected to the rotating seat 22 to drive its rotation.

[0046] Reference Figure 2 The platform mechanism 3 includes a platform base 31 and a work station plate 32. The platform base 31 is fixed to the top of the rotating seat 22 and is coaxial with the rotating seat 22; see reference. Figure 3 The top of the platform base 31 is fixed with several connecting columns 311, and the workstation plate 32 is fixed to the connecting columns 311, so that the workstation plate 32 and the platform base 31 are spaced apart and form an accommodating space. The accommodating space is provided with a manifold mold base 34 and a negative pressure mold base 33. The manifold mold base 34 is fixed to the bottom of the workstation plate 32 by fasteners. The bottom of the manifold mold base 34 is provided with an extension 341, which passes through the inner side of the rotating seat 22 of the rotating mechanism 2 and is coaxially arranged with the platform base 31.

[0047] Multiple negative pressure mold bases 33 are provided, and all negative pressure mold bases 33 are equidistantly arranged around the central axis of the platform base 31. In this embodiment, each negative pressure mold base 33 is fixed to the top surface of the platform base 31 by fasteners, so that the negative pressure mold base 33 can rotate with the platform base 31, thereby realizing circumferential linkage between the negative pressure mold base 33 and the platform mechanism 3. The workstation plate 32 has multiple workstation slots 321, and the number of workstation slots 321 is set to be equal to the number of negative pressure mold bases 33. Each negative pressure mold base 33 is matched and located in its respective workstation slot 321, and the top surface of the negative pressure mold base 33 can be flush with the top surface of the workstation plate 32.

[0048] Reference Figure 2 , Figure 3The negative pressure mold base 33 is configured as a shell structure. The top surface of the negative pressure mold base 33 is provided with a negative pressure hole 331 that communicates with the interior. Several first air passage connectors 332 are connected to the side of the negative pressure mold base 33. Several second air passage connectors 342 are connected to each side of the manifold mold base 34. The first air passage connectors 332 and the adjacent second air passage connectors 342 are connected by hoses (not shown in the figure), so that each negative pressure mold base 33 is connected to the manifold mold base 34.

[0049] Additionally, refer to Figure 4 The bottom of the manifold mold base 34 is provided with a pipeline mechanism 6. The manifold mold base 34 is connected to a negative pressure generator 7 through the pipeline mechanism 6. The negative pressure generated by the negative pressure generator 7 can be dispersed to each negative pressure mold base 33, so that when the heat transfer carrier is placed in the negative pressure mold base 33, it can be adsorbed by the negative pressure and achieve a stable positioning effect.

[0050] Back Figure 1 It should be noted that in this embodiment, the number of negative pressure mold bases 33 is set to four, and the positions of each negative pressure mold base 33 can be arranged in a counterclockwise direction as loading station 35, labeling station 36, hot pressing station 37, and unloading station 38. However, it is understood that in other feasible embodiments, the number of negative pressure mold bases 33 can also be 5, 6, or 7, and is not limited to the number shown in this embodiment.

[0051] Reference Figure 5 The piping mechanism 6 includes a connector seat 61 and a pipe assembly 63. A connecting member 62 is provided on the outer periphery of the connector seat 61. The connecting member 62 includes a clamping ring 621 fixedly sleeved on the outer periphery of the connector seat 61 and two connecting plates 622 connected to the clamping ring 621. Two shaft members 11 are fixedly connected to the bottom of the workbench of the frame assembly 1. The two connecting plates 622 are detachably fixed to the two shaft members 11, thereby fixing the connector seat 61 inside the frame assembly 1. Additionally, returning to... Figure 4 The outer peripheral surface of the connector 61 is partially provided with an air passage interface 611. The negative pressure generator 7 is fixed to the inner bottom of the frame assembly 1, and the negative pressure port of the negative pressure generator 7 is connected to the air passage interface 611 through a hose (not shown in the figure), which can provide negative pressure suction to the inside of the connector 61.

[0052] Reference Figure 6The connector assembly 63 includes a first pipe section 631, a second pipe section 632, and a third pipe section 633. The outer diameter of the first pipe section 631 is equal to the inner diameter of the connector seat 61, allowing it to be fitted inside the connector seat 61. A return spring 612 is also provided inside the connector seat 61. One end of the return spring 612 abuts against the inner bottom wall of the connector seat 61, and the other end abuts against the first pipe section 631. The return spring 612 can always generate an elastic force acting on the first pipe section 631, normally forcing the first pipe section 631 to move upwards.

[0053] The outer diameter of the second pipe section 632 is equal to that of the first pipe section 631. A bearing is fixed to the outer circumference of the second pipe section 632, allowing it to rotatably mount on the inner wall of the connector seat 61. The bottom end of the second pipe section 632 abuts against the first pipe section 631 and remains coaxial with it, with internal communication between the two. (See also...) Figure 4 The third pipe section 632 is fixedly connected to the bottom of the extension 341 of the manifold base 34, and the third pipe section 633 and the extension 341 are coaxial; the bottom end of the inner cavity of the third pipe section 632 is provided with a flared part, and the top end of the second pipe section 632 is provided with a constricted part, and the flared part can be fitted with the constricted part.

[0054] Based on this, in this embodiment, the elastic force generated by the return spring 612 acting on the first tube segment 631 can force the first tube segment 631 to press against the second tube segment 632, while maintaining a tight fit between the second tube segment 632 and the third tube segment 633, ensuring a good sealing effect. When the rotating mechanism 2 rotates and drives the platform mechanism 3 to rotate, the second tube segment 632 can rotate relative to the connector seat 61 through the bearing, thereby ensuring that the negative pressure of the negative pressure mold seat 33 is maintained during the rotation, which helps the heat transfer carrier to smoothly follow the rotation of the platform mechanism 3.

[0055] It should also be noted that by removing the connecting plate 622 from the shaft member 11, the first pipe section 631, the second pipe section 632 and the third pipe section 633 can be easily separated and disassembled, which facilitates the quick disassembly and cleaning of the connector seat 61 and the pipeline mechanism 6, and reduces the possibility that the accumulation of dust inside the connector seat 61 and the pipeline mechanism 6 may affect the adsorption effect.

[0056] Back Figure 1The cutting and transferring mechanism 4 is located on the top of the frame assembly 1 and is situated on the rotation path of the negative pressure mold base 33, essentially at the label station 36. The specific structure of the cutting and transferring mechanism 4 is identical to that disclosed in the existing patent application publication number CN114084722A, and is not the focus of this case; therefore, it will not be elaborated upon here. It can be understood that when the heat transfer carrier is adsorbed by the negative pressure mold base 33 and rotates with the platform mechanism 3 to the label station 36, the cutting and transferring mechanism 4 can automatically cut and transfer the entire roll of labels. Finally, a single label can be placed on the surface of the heat transfer carrier. Due to the presence of negative pressure, the single label can be tightly adsorbed onto the surface of the heat transfer carrier by the negative pressure.

[0057] The hot pressing mechanism 5 is also located on the top of the frame assembly 1. It is situated on the moving path of the negative pressure mold base 33 and at the rear end of the cutting and transfer mechanism 4, essentially at the hot pressing station 37. The specific structure of the hot pressing mechanism 5 is a conventional design in this field and is not the focus of this case; therefore, it will not be elaborated further here. It can be understood that when the heat transfer carrier and a single label rotate with the platform mechanism 3 to the hot pressing station 37, the hot pressing mechanism 5 can press and heat the label to integrally form it onto the heat transfer carrier. The resulting transfer product can then rotate with the platform mechanism 3 to the unloading station 38 for safe removal by the operator.

[0058] Reference Figure 2 The frame assembly 1 has multiple sets of support units 8 near the platform mechanism 3, which support the platform base 31. In this embodiment, there are four sets of support units 8, which are evenly distributed around the rotation axis of the rotating mechanism 2 and are positioned below the four workstations. Specifically, the support unit 8 includes a fixed support column 81 and a rolling component 82. The fixed support column 81 is threaded to the frame assembly 1 and is vertically arranged. The rolling component 82 is rotatably connected to the top of the fixed support column 81, and the platform base 31 normally rests against the rolling component 82.

[0059] It should be noted that the rolling component 82 in this embodiment is a bearing, but in other feasible embodiments, the rolling component 82 may also be a rotatable component such as a roller or ball, and is not limited to the manner shown in this embodiment.

[0060] In addition, in this embodiment, the support unit 8 located below the hot pressing mechanism 5 is defined as the main load-bearing unit 83. The main load-bearing unit 83 includes multiple fixed support columns 81. The specific number can be two or more, without specific limitation, as long as it can meet the load-bearing capacity of the platform mechanism 3 when the hot pressing mechanism 5 is working. All fixed support columns 81 are equidistantly arranged around the work station center of the hot pressing mechanism 5, and the top of each fixed support column 81 is rotatably connected to the aforementioned rolling component 82. This can enhance the load-bearing capacity of the platform mechanism 3 when the hot pressing mechanism 5 performs heat transfer on the carrier, and reduce the possibility of the platform mechanism 3 being deformed or displaced under pressure.

[0061] The implementation principle of a multi-station roll cutting and labeling machine according to an embodiment of this application is as follows:

[0062] When the operator is working, the negative pressure generator 7 remains running, continuously drawing air from the connector seat 61, pipeline mechanism 6, manifold mold seat 34, and negative pressure mold seat 33 to create negative pressure. The operator places the heat transfer carrier on the negative pressure mold seat 33, and the heat transfer carrier can be attracted by the negative pressure of the negative pressure hole 331. By controlling the drive structure 23 to move, the rotating seat 22 and the platform mechanism 3 are driven to rotate. The heat transfer carrier can move sequentially to the label station 36, the hot pressing station 37, and the unloading station 38, thereby automatically completing a series of processes such as label placement and hot pressing transfer. The operator can take out the transferred finished product at the unloading station 38. Since the loading station 35 and the hot pressing station 37 are separated, the possibility of accidental hand crushing by the hot pressing mechanism 5 is greatly reduced, improving the safety factor.

[0063] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
