Description

Technical Field

[0001] The utility model relates to the technical field of heat transfer printers, in particular to a high-precision paper pressing wheel applied to a heat transfer machine. Background Art

[0002] A heat transfer printer is a device used to print patterns onto various materials through thermal transfer technology. The pinch roller is an important component in the heat transfer machine, used to ensure smooth transportation and precise positioning of the paper during the printing process. The pinch roller fixes the paper in the correct position by applying appropriate pressure to prevent it from moving or offsetting during the printing process.

[0003] Although the pinch wheel in the prior art has many benefits during use, it still has the following problems: the existing pinch wheel mechanism is fixed in a fixed position, which results in the paper feeding direction at the rear having to be from bottom to top, and cannot achieve a paper feeding trajectory from top to bottom, resulting in limitations in the paper heat transfer processing. Utility Model Content

[0006] By adopting the above technical solution, the fixed plate can keep the rotation angle outside the support plate controlled through the bearing sleeve, connecting shaft and clamping sleeve, and the second hook cooperates with the first hook to connect the retaining spring, keeping the retaining spring in a stable position between the fixed plate and the support plate.

[0007] Specifically, a support frame is installed on the outer wall of one end of the support plate, and a paper pressing roller is rotatably installed inside the support frame.

[0008] By adopting the above technical solution, the paper pressing roller maintains a stable rotation position inside the support frame, and the paper pressing roller can squeeze the paper outside the central axis.

[0009] Specifically, the fixing plate is designed in an L-shape, the fixing plate is provided with fixing holes that are equidistant and parallel to each other, and a crossbeam is provided on an outer wall of one side of the fixing plate.

[0010] By adopting the above technical solution, the fixing plate can be screwed into the interior of the beam through the external bolts passing through the fixing hole, so that the fixing plate can be fixed to the outside of the beam, maintaining the stability of the connection between the fixing plate and the beam, and keeping the use position of the support plate relatively stable.

[0011] Specifically, a connecting shaft is rotatably installed inside the bearing sleeve, and outer walls at both ends of the connecting shaft are connected to the clamping sleeve.

[0012] By adopting the above technical solution, the support plate can be rotated outside the fixed plate through the bearing sleeve, the connecting shaft and the clamping sleeve, so that the use angle of the support plate and the paper pressing roller can be adjusted.

[0013] Specifically, first hooks are installed on the outer walls of both sides of the support plate, a clip is hung on the outer side of the first hook, and the other end of the clip is connected to the second hook.

[0014] By adopting the above technical solution, the first hook and the second hook can keep the use position of the retaining spring stable, and the tension of the retaining spring can pull one end of the support plate to rotate toward the fixed plate, keeping the relative position between the fixed plate and the support plate stable, and the generated tension can push the paper pressing roller to ensure the squeezing force of the paper pressing roller on the center axis.

[0015] Specifically, support shafts are installed on the outer walls of both sides of the support plate, and paper guide wheels are rotatably installed on the outer sides of the support shafts.

[0016] By adopting the above technical solution, the paper guide wheel maintains a stable position outside the support shaft, and the paper guide wheel can limit and guide the moving trajectory of the paper.

[0017] Specifically, a central shaft is provided on the outer side of the support plate, and the central shaft is located at the lower end of the paper pressing roller.

[0018] By adopting the above technical solution, the central shaft can be driven to rotate by an external power structure, and the paper is driven to move by the central shaft, which can ensure the transportation of the paper, and the paper can be flattened by squeezing the paper through the central shaft and the paper pressing roller.

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] In order to save manpower and improve efficiency, as an embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, a high-precision paper pressing wheel of the present invention is used in a heat press machine, comprising a support plate 1, a fixed plate 6 and a paper pressing roller 3. Bearing sleeves 4 are installed on both sides of the outer wall of the upper end of the support plate 1, a fixed plate 6 is provided on the outer wall of the upper end of the support plate 1, and clamping sleeves 7 are installed on both sides of the lower end of the outer wall of the fixed plate 6. Second hooks 11 are installed on the upper ends of the outer walls of both sides of the fixed plate 6.

[0030] When in use, the fixed plate 6 can keep the rotation angle outside the support plate 1 controlled through the bearing sleeve 4, the connecting shaft 5 and the clamping sleeve 7, and the second hook 11 cooperates with the first hook 10 to connect the retaining spring 12, keeping the retaining spring 12 in a stable position between the fixed plate 6 and the support plate 1. The support plate 1 is designed with plastic material, the fixed plate 6 is designed with metal material, and the outer wall of the paper pressing roller 3 is designed with rubber material.

[0031] For pressing paper, for example, Figure 2 As shown, a support frame 2 is installed on the outer wall of one end of the support plate 1, and a paper pressing roller 3 is rotatably installed inside the support frame 2.

[0032] When in use, the paper pressing roller 3 maintains a stable rotation position inside the support frame 2 , and the paper pressing roller 3 can press the paper outside the central axis 14 .

[0033] In order to fix the fixing plate 6, for example, Figure 4 As shown, the fixing plate 6 is designed in an L-shape, and fixing holes distributed equidistantly and parallelly are opened inside the fixing plate 6 . A crossbeam 13 is provided on the outer wall of one side of the fixing plate 6 .

[0034] When in use, the fixing plate 6 can be screwed into the interior of the beam 13 through the external bolts passing through the fixing holes, so that the fixing plate 6 can be fixed to the outside of the beam 13, maintaining the stability of the connection between the fixing plate 6 and the beam 13, and keeping the use position of the support plate 1 relatively stable.

[0035] To maintain the rotational position, for example, Figure 1 As shown, a connecting shaft 5 is rotatably mounted inside the bearing sleeve 4 , and outer walls at both ends of the connecting shaft 5 are connected to the clamping sleeve 7 .

[0036] When in use, the support plate 1 can rotate outside the fixed plate 6 through the bearing sleeve 4, the connecting shaft 5 and the clamping sleeve 7, so as to ensure that the use angle of the support plate 1 and the paper pressing roller 3 can be adjusted.

[0037] In order to maintain the squeezing force, for example, Figure 1 As shown, first hooks 10 are installed on the outer walls of both sides of the support plate 1 , a clip 12 is hung on the outer side of the first hook 10 , and the other end of the clip 12 is connected to the second hook 11 .

[0038] When in use, the first hook 10 and the second hook 11 can keep the use position of the retaining spring 12 stable, and the tension of the retaining spring 12 can pull one end of the support plate 1 to rotate toward the fixed plate 6, keeping the relative position between the fixed plate 6 and the support plate 1 stable, and the generated tension can push the paper pressing roller 3 to ensure the squeezing force of the paper pressing roller 3 on the center axis 14.

[0039] For paper guidance, for example, Figure 1As shown, support shafts 8 are installed on the outer walls of both sides of the support plate 1, and paper guide wheels 9 are rotatably installed on the outer sides of the support shafts 8.

[0040] When in use, the paper guide wheel 9 maintains a stable position outside the support shaft 8, and the paper guide wheel 9 can limit and guide the moving trajectory of the paper.

[0041] For paper transport, for example, Figure 4 As shown, a central shaft 14 is provided on the outer side of the support plate 1 , and the central shaft 14 is located at the lower end of the paper pressing roller 3 .

[0042] When in use, the central shaft 14 can be driven to rotate by an external power structure, and the paper is driven to move by the central shaft 14, which can ensure the transportation of the paper, and the paper is squeezed by the central shaft 14 and the paper pressing roller 3, so that the paper can be flattened.

[0043] When the utility model is in use, the staff installs the paper pressing roller 3 inside the support frame 2 to maintain the stability of the use position of the paper pressing roller 3, and the staff fixes the paper guide wheel 9 with screws to keep the position of the paper guide wheel 9 on the outside of the support shaft 8 stable, and the paper guide wheel 9 guides the paper moving from above to below;

[0044] The staff connected the connecting shaft 5 to the fixed plate 6 to ensure that the circumferential rotation position of the fixed plate 6 was controlled by the connecting shaft 5. Afterwards, the staff hung the two ends of the clamping spring 12 on the outside of the first hook 10 and the second hook 11 respectively. The tension generated by the clamping spring 12 can pull the support plate 1. The tension driven by the clamping spring 12 can push the paper pressing roller 3, maintaining the squeezing force of the paper pressing roller 3 on the central shaft 14;

[0045] The staff takes screws and passes them through the fixing holes to fix the fixing plate 6 to the outside of the beam 13.

[0046] The external drive mechanism can drive the central shaft 14 to rotate in a circular motion, so that when the paper is driven to move outside the central shaft 14, the paper can move out between the central shaft 14 and the paper pressing roller 3. The paper is squeezed and flattened by the squeezing force of the paper pressing roller 3 on the paper outside the central shaft 14.
