Description

Technical Field

[0001] The utility model belongs to the technical field of film curing, and in particular relates to a curing heating device for printed films. Background Art

[0002] By heating the film to a specific temperature and holding it for a certain period of time, the components in the film undergo chemical reactions or physical changes, thereby achieving curing. During the thermal curing process, the temperature and time need to be strictly controlled. Too high a temperature may damage the film's performance, while too low a temperature will not achieve a good curing effect. Too long a time will waste energy and production time, while too short a time will result in incomplete curing. During the process of fixing the film, it is necessary to ensure that the temperature is evenly distributed on the surface of the film to avoid local overcooling or overheating. In the existing technology, thermal cycling is usually used to cure the film, but the air outlet of the thermal cycle is usually concentrated in one place, and the hot air blown out cannot heat the film evenly across the area. Utility Model Content

[0003] In view of the problems raised by the above background technology, the purpose of the present invention is to provide a curing heating device for printed films to solve the problems raised by the above background technology.

[0004] In order to achieve the above technical objectives, the technical solutions adopted by this utility model are as follows:

[0005] A curing and heating device for printed films, comprising a support cabinet, a conveyor mounted on the support cabinet, a heating box mounted on the conveyor, a hot air system mounted in the heating box, a reciprocating movable plate slidably mounted below the hot air system, the movable plate having a strip groove perpendicular to the moving direction, slide rails mounted on both sides of the movable plate, and a reciprocating mechanism mounted between the movable plate and the slide rails in the heating box;

[0006] The reciprocating mechanism includes a rack frame with racks symmetrically arranged above and below, the rack frame is fixedly connected to the moving plate, the rack frame is meshed and connected with sector teeth, and the output shaft of the sector teeth is transmission-connected to a motor assembled with a slide rail.

[0007] Preferably, the distance that the rack frame moves in one direction when the sector teeth rotate is the same as the width of the strip groove, and the edge distance between two adjacent strip grooves of the movable plate is the same as the width of the strip groove.

[0008] Preferably, the hot air system includes a fan assembled and connected to the upper side of the heating box, and the lower side of the fan is provided with an electric heating component assembled and connected to the heating box. The fan and the electric heating component are assembled and connected in an assembly frame fixedly connected to the heating box.

[0009] Preferably, the electric heating component is an electric heating wire mesh.

[0010] Preferably, a cleaning mechanism is assembled and connected to the lower part of one side of the conveyor, and the cleaning mechanism includes a cleaning sleeve, and a connecting column is fixedly connected inside the cleaning sleeve, and both ends of the connecting column are assembled and connected to the conveyor.

[0011] Preferably, springs assembled and connected to both ends of the connecting column are assembled on both sides of the conveyor, and the springs abut against the end of the cleaning sleeve.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] The utility model drives the movable plate to move by the reciprocating movement mechanism, thereby making the strip grooves of the movable plate move back and forth. Under the operation of the fan, the air will move in the direction of the movable plate along the wind direction. When the air movement is resisted by the movable plate, the air will move in the direction of less resistance, so that the air heated by the electric heating component is discharged from the strip grooves of the movable plate, so that the hot air will be discharged from the strip grooves with less resistance. In the process of the reciprocating movement of the movable plate, the blown hot air can be evenly distributed on the printed film, so that the printed film is heated evenly.

[0014] The utility model makes the wind blown out from the strip groove more concentrated by setting the movable plate without adding air outlet components, thereby making the wind force of the wind discharged from the strip groove more consistent, so that the temperature of the hot air can be more easily adjusted by adjusting the temperature of the electric heating component.

[0015] The utility model cleans the conveyor by arranging a cleaning sleeve under the conveyor, thereby reducing dust on the conveyor. At the same time, the cleaning sleeve can be disassembled, which is convenient for cleaning and replacing the cleaning sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0031] Example 1: Figure 1-7 As shown, a curing and heating device for printed films includes a support cabinet 1, a conveyor 2 is assembled and connected above the support cabinet 1, a heating box 3 is provided above the conveyor 2, a hot air system 400 is provided in the heating box 3, a reciprocating movable plate 5 is slidably connected below the hot air system 400, the movable plate 5 has a strip groove perpendicular to the moving direction, and slide rails 110 are slidably connected on both sides of the movable plate 5, and a reciprocating moving mechanism 600 is assembled and connected between the movable plate 5 and the slide rails 110 in the heating box 3;

[0032] The reciprocating mechanism 600 includes a rack frame 610 with racks symmetrically arranged above and below. The rack frame 610 is fixedly connected to the moving plate 5. The rack frame 610 is internally meshed with a sector tooth 620, and the output shaft of the sector tooth 620 is transmission-connected to a motor 630 assembled with the slide rail 110.

[0033] By adopting the technical solution of this embodiment, the printed film is moved to the bottom of the heating box 3 under the drive of the conveyor 2, and the heating box heats and cures the printed film. The hot air system 400 forms a relatively closed space in the heating box 3 to concentrate the heat generated by the hot air system 400. The movable plate 5 prevents the heat generated by the hot air system from being directly dissipated, reduces the air outlet area below the hot air system, and at the same time makes the heat discharged from the strip groove more concentrated. The movable plate 5 slides along the slide rail 1110, and the reciprocating mechanism 600 drives the movable plate 5 to move back and forth, so that the hot air blown out from the strip groove is uniform. The rack frame 610 is distributed on the film so that the film is heated evenly. The rack frame 610 is a straight notch type or a rectangular type. When the sector teeth 620 rotate 1 to engage with the rack frame 610 above, the rack frame 610 rotates in one direction. When the sector teeth 620 rotate to engage with the rack below, the rack frame 610 rotates in the other direction, so that the rack frame 610 drives the movable plate 5 to move back and forth. The unidirectional rotation of the motor 610 can realize the reciprocating rotation of the movable plate 5. Buffers for the movable plate 5 are provided on both sides of the heating box 3 to reduce the impact of the movable plate 5 on the heating box 3 during the reciprocating movement.

[0034] Example 2: Reference Figure 6 This embodiment further defines the strip grooves of the movable plate 5 based on the first embodiment. The rotation of the sector teeth 620 drives the rack frame 610 to move in one direction a distance equal to the width of the strip grooves. The distance between the edges of two adjacent strip grooves of the movable plate 5 is equal to the width of the strip grooves. When the sector teeth 620 rotate, the rack frame 610 moves in opposite directions when the sector teeth 620 engage with the upper rack and the lower rack, causing the movable plate between the two strip grooves to reciprocate between the adjacent strip grooves and the movable plate.

[0035] Example 3 3: With reference to the figure: This example further defines the hot air system 400 based on Example 1. The hot air system 400 includes a fan 410 assembled and connected to the upper side of the heating box 3. The lower side of the fan 410 is provided with an electric heating component 420 assembled and connected to the heating box 3. The fan 410 and the electric heating component 420 are assembled and connected in an assembly frame fixedly connected to the heating box 3. The electric heating component 420 can be a heating tube, a heating wire, or other components. An air inlet is opened above the assembly frame, and outside air enters the assembly frame through the air inlet.

[0036] Reference Figure 3 : The electric heating component 420 is an electric heating wire mesh.

[0037] Example 4: Reference Figure 2 and Figure 7This embodiment further defines the cleaning mechanism 700 based on the first embodiment. The cleaning mechanism 700 is assembled and connected to the lower portion of one side of the conveyor 2. The cleaning mechanism 700 includes a cleaning sleeve 710. A connecting post 720 is fixedly connected to the cleaning sleeve 710. Both ends of the connecting post 720 are assembled and connected to the conveyor 2. The cleaning sleeve 710 contacts the conveyor belt of the conveyor 2 and is used to clean dust attached to the conveyor belt.

[0038] Example 5: Reference Figure 2 This embodiment further defines the ends of the connecting post 720 based on the fourth embodiment. Springs 730 are assembled and connected to both ends of the connecting post 720 on both sides of the conveyor 2. The springs 730 abut the ends of the cleaning sleeve 710. The connecting posts 720 at both ends are located within the springs. By pressing one end of the cleaning sleeve 710 against the spring 730 and removing the connecting post 720 at the other end from the spring 730, the cleaning sleeve 710 can be removed.

[0039] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0040] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical principles disclosed herein shall be covered by the claims of the present invention.
