Description

Technical Field

[0001] This application relates to the technical field of thermal transfer, and particularly to an automatic thermal transfer machine. Background Art

[0002] Thermal transfer is a very mature printing process. It pre-prints a color pattern on a heat-resistant substrate film, and then, in cooperation with a special transfer machine, transfers the pattern on the substrate film to the surface of the product by means of hot stamping. The printed pattern has the characteristics of rich layers, bright colors, ever-changing, and small color difference, which can well meet the requirements of designers and is suitable for the needs of modern large-scale production.

[0003] The structure of a thermal transfer machine generally includes a frame. A film feeding roller, a film winding roller, and a tension roller are arranged on the frame. At the same time, a hot pressing device is also arranged. The transfer film on the film feeding roller enters between the hot pressing device and the transfer object through the tension roller. The hot pressing device presses down to transfer the item to the transfer object. Currently, the thermal transfer machines on the market generally use manual loading and unloading, and it is necessary to manually place the transfer object and take out the finished product after the transfer is completed. For some small-sized transfer objects, such as pen barrels, the operation is time-consuming and laborious, and the efficiency is low. Utility Model Content

The lifting roller includes a first lifting drive, a material pushing roller, and a fixed roller. Matching inclined surfaces are arranged on the material pushing roller and the fixed roller. A second lifting drive is connected to the material pushing roller.

[0007] Preferably, the roller fixing frame includes a horizontally arranged frame. A plurality of adjusting rods are movably connected to both sides of the frame. A film feeding roller, a tension roller, and a film winding roller are arranged between the adjusting rods. The transfer film passes through the feeding roller and the tension roller and then enters between the hot pressing device and the lifting roller, and finally winds and collects on the winding roller.

[0008] Preferably, the feeding box further includes a vertically arranged fixing plate. The horizontal cross-section of the fixing plate is in an inverted U shape. The feeding plate is arranged in the middle of the fixing plate. An outlet is arranged at a position on the side of the fixing plate corresponding to the lower end of the feeding plate.

[0012] Preferably, fixing blocks are arranged below both the top feeding roller and the fixed roller and the fixing blocks are in contact with the bottom plate. The upper and lower parts of the sides of the two fixing blocks close to each other are provided with inclined surfaces at the same angle. An elastic member is arranged on the side of the fixed roller away from the top feeding roller.

[0013] Preferably, a receiving groove is arranged on the workbench. The receiving groove is located on the side of the fixed roller and the receiving groove is inclined.

[0014] In summary, the present application includes at least one of the following beneficial technical effects:

[0015] 1. In the present application, by arranging a feeding box on the workbench and arranging an inclined feeding plate in the feeding box, the workpiece can fall freely. At the same time, a feeding mechanism is arranged below the feeding box, and automatic feeding is realized through the reciprocating movement of the feeding mechanism; by arranging a lifting roller below the hot pressing device, the transfer object can be lifted for transfer operation. At the same time, an inclined surface is arranged between the top feeding roller and the fixed roller, and the top feeding roller can be driven to rise by the second lifting drive. When the top feeding roller rises, the fixed roller moves horizontally, and finally the transferred finished product is pushed out, which is convenient for operation and saves time and effort.

[0016] 2. By setting a fixing plate with an inverted U-shaped cross-section and an opening on one side, it is convenient to place the transfer object. At the same time, an inclined feeding plate is arranged in the middle of the fixing plate. A discharge port is arranged at the lower end of the fixing plate corresponding to the feeding plate, and the size of the discharge port corresponds to the size of the pen holder, which can ensure that only one pen holder can fall each time and guarantee the feeding progress. By arranging a feeding groove below the discharge port and a feeding plate between the discharge port and the feeding groove, the feeding plate can push the pen holder falling into the feeding groove to the lifting roller. At the same time, the distance between the feeding plate and the discharge port is less than the diameter of the pen holder, and the feeding plate can play the role of closing the feeding plate to ensure single pen holder feeding one by one.

[0017] 3. By arranging a bottom plate at the bottom of the lifting frame and the edge of the bottom plate exceeding the lifting frame, the first lifting drive can be installed. The first lifting drive drives the lifting frame to rise or fall, and then drives the lifting roller to rise or fall to send the transfer object to be connected with the hot pressing device. At the same time, a second lifting drive is arranged below the top feeding roller, which can drive the top feeding roller to move through the second lifting drive. Combining the inclined surfaces arranged on the top feeding roller and the fixed roller, and the elastic member arranged on the side of the fixed roller, after the transfer is completed, the second lifting drive drives the top feeding roller to move upward, and at the same time, the fixed roller moves horizontally under the action of the elastic member and the inclined surface. Finally, the top feeding roller ejects the transferred transfer object to achieve automatic discharging, which is convenient for operation, time-saving and labor-saving. Description of the Drawings

The horizontal cross-section of the fixing plate 602 is in an inverted U shape. A material feeding plate 601 is arranged in the middle of the fixing plate 602. The material feeding plate 601 is arranged to incline downward. A plurality of pen holders to be heat transferred are placed on the material feeding plate 601. A discharging port 603 is arranged at the position corresponding to the lower end of the material feeding plate 601 on the side surface of the fixing plate 602. The size of the discharging port 603 corresponds to the size of the pen holder. A feeding mechanism 7 is arranged below the side surface of the material feeding box 6. The feeding mechanism 7 reciprocates between the lifting roller 5 and the material feeding box 6. The feeding mechanism 7 includes a feeding groove 701 and a feeding drive 702 arranged on the side surface of the feeding groove 701. The feeding groove 701 is located below the discharging port 603. The cross-section of the feeding groove 701 is in a "V" shape. The feeding drive 702 is a double-stroke cylinder. A feeding plate 703 is connected to the feeding drive 702. The feeding plate 703 is located between the feeding groove 701 and the discharging port 603 and the distance between the feeding plate 703 and the discharging port 603 is less than the diameter of the pen holder. Specifically, the feeding plate 703 is a square plate and a long strip-shaped convex strip is arranged on the side surface of the feeding plate 703. The convex strip is located above the feeding groove 701. During the feeding process, the convex strip can block the discharging port 603 to ensure single-piece feeding. The height of the feeding groove 701 matches the height of the lifting roller 5. The distance between the end of the feeding groove 701 and the lifting roller 5 is less than the length of the pen holder.

[0029] Reference Figures 1 to 6 As shown in Figures 1 to 6 , the lifting roller 5 includes a lifting frame 505. Specifically, in this actual example, a square hole is provided on the workbench 1 corresponding to the lower part of the hot pressing device. The lifting frame 505 is clamped in the square hole. A bottom plate is provided at the bottom of the lifting frame 505 and the bottom plate extends beyond the lifting frame 505. A blanking roller 502 and a fixed roller 503 are provided on the bottom plate inside the lifting frame 505. Fixed blocks are provided below both the blanking roller 502 and the fixed roller 503 and the fixed blocks are connected to the bottom plate. A fixing plate is provided on the fixed block and is connected to the blanking roller 502 and the fixed roller 503 through the fixing plate. The fixing plates of the blanking roller 502 and the fixed roller 503 are bent towards each other, and the rollers on the blanking roller 502 and the fixed roller 503 approach each other. A receiving groove 8 is provided on the workbench 1. The receiving groove 8 is inclined and arranged on the side of the fixed roller 503. The upper and lower parts of the mutually close sides of the two fixed blocks are provided with inclined surfaces at the same angle. An elastic member is provided on the side of the fixed roller 503 away from the blanking roller 502. The elastic member is a spring. Specifically, in this embodiment, the fixed blocks on the blanking roller 502 and the fixed roller 503 are connected to the inside of the lifting frame 505.

A second lifting drive 504 is provided below the blanking roller 502 and the second lifting drive 504 is connected to the bottom plate.

[0030] The implementation principle is as follows: When this application is in use, the staff first place a plurality of pen barrels or pen rods to be transferred in a certain direction on the feeding plate 601. Since the feeding plate 601 is inclined and the discharging port 603 is provided on the fixing plate 602, a single pen barrel falls into the feeding groove 701 through the discharging port 603. Since the feeding plate 703 is provided above the feeding groove 701, the feeding plate 703 can push the pen barrel between the lifting rollers 5. Then the first lifting drive 501 acts to raise the lifting frame 505 until the pen barrel can be connected to the hot pressing device 4. The transfer film performs a transfer operation between the pen barrel and the hot pressing device 4. After the transfer is completed, the first lifting drive 501 controls the lifting frame 505 to move down and reset. Then the second lifting drive 504 acts to drive the blanking roller 502 to rise. Since the fixed blocks of the fixed roller 503 and the blanking roller 502 are provided with mutually cooperating inclined surfaces, and at the same time an elastic member is provided on the side of the fixed roller 503, the fixed roller 503 can move horizontally when the blanking roller 502 ejects, and then the transferred pen barrel is ejected through the blanking roller 502 and finally falls into the receiving groove 8, which is convenient for collection. The overall structure is simple, the operation is convenient, and it saves time and effort.

[0031] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
