Description

Technical Field

[0001] The invention relates to a semi-finished license plate feeding mechanism, in particular to a semi-finished license plate automatic feeding thermostatic box and a use method thereof. Background Art

[0002] The production process of license plates mainly includes the following steps: 1. Unfolding of aluminum; 2. Applying reflective film on the surface of aluminum plate; 3. Printing one side of blue ink on the reflective film; After the first three steps, a semi-finished license plate is obtained; 4. According to the license plate number, under the operation of the vehicle management office staff, the corresponding Chinese characters / letters / numbers are stacked in the bottom mold, sorted one by one, and the blank license plate semi-finished license plate is put into the pressing machine for stamping; 5. Wipe out the license plate number, use cotton cloth dipped in organic solvent, and gently wipe the semi-finished license plate. Since the place with words has been stamped and raised, the paint here is very easy to dissolve in the potion, revealing the previously covered white reflective film. In order to facilitate better pressing of the license plate number and prevent the paint film from falling off and being damaged by impact, the semi-finished license plate is generally heated so that the paint film can perform at its best performance. However, the existing semi-finished license plate is generally heated in an oven and pressed immediately after heating, so it is necessary to wait until the license plate is pressed before heating, and it cannot be used immediately, which is inefficient. Therefore, the existing technology has the problem of low efficiency. Summary of the invention

[0013] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0014] Embodiment. A thermostatic box for automatic feeding of semi-finished license plates, comprising: Figure 1 to Figure 2 As shown, it includes a box body 1, a heating plate 2 is provided at the bottom of one side of the box body 1, an upper limit block 3 and a lower limit block 4 are respectively provided at the upper and lower ends of the other side of the box body 1, and a vertical screw mechanism 5 is also provided on the other side of the box body 1, and a supporting tray 6 is provided on the vertical screw mechanism 5; the upper end of the box body 1 is provided with a discharge port 7 corresponding to the supporting tray 6, and photoelectric sensors 8 are provided on both sides of the discharge port 7.

[0015] A temperature sensor 9 is also provided in the box body 1 .

[0016] A preheating rack 10 is also provided in the middle of one side of the box body 1 .

[0017] A method for using a thermostatic box for automatic feeding of semi-finished license plates, which uses a heating plate to preheat the semi-finished license plates on a supporting tray to a set temperature, monitors the taking status of the semi-finished license plates at a discharge port through a photoelectric sensor, controls a vertical screw mechanism to replenish materials in time, and ensures that the temperature of the semi-finished license plates is constant when they are taken away.

[0018] The preheating rack preheats the semi-finished license plates to be placed on the tray.

[0019] The heating plate is an electric heating plate.

[0020] The box body is also provided with a controller, which is respectively connected with the temperature sensor, the photoelectric sensor and the vertical screw mechanism.

[0021] The use process of the present invention is as follows: when using it for the first time, manually place the semi-finished license plate on the support tray, start the heating switch, and the heating plate starts to heat. After heating to the set temperature, the mode is changed from manual to automatic, and the photoelectric sensor checks whether there is an object blocking the discharge port. If there is an object blocking it, the status quo is maintained. If there is no obstruction, the vertical screw mechanism starts to rotate, driving the support tray to rise. When the photoelectric sensor detects that there is an object (semi-finished license plate) blocking it, the vertical screw mechanism stops. After the semi-finished license plate at the discharge port is taken away, the vertical screw mechanism continues to operate until the photoelectric sensor detects that there is an object blocking it again, and the vertical screw mechanism stops; repeat the above process until the semi-finished product on the support tray is used up. The preheating rack preheats the semi-finished license plate. After the semi-finished license plate on the support tray is used up, the semi-finished license plate on the preheating rack is directly moved to the support tray for use.

[0022] A push plate is provided at one end of the preheating rack, and a cylinder matched with the push plate is provided on the outer side of the box body.

[0023] The support tray includes a chassis fixed on a vertical screw mechanism, and baffles are provided on the front and rear sides of the chassis; slide grooves are provided on the front and rear side walls of the chassis, and vertical slide bars matching the slide grooves are provided on the baffles; a tension reset spring is provided between the bottom of the chassis and the bottom of the baffle. The setting of this structure is not only convenient for the subsequent transfer of the semi-finished license plates on the preheating rack to the support tray, but also convenient for the stability of the placement of the semi-finished license plates on the support tray during the feeding process, and is not easily affected by external vibrations. During the feeding process, the baffle rises with the chassis first, and when it rises to a certain position, the upper end of the baffle contacts the top wall of the box body, and then the chassis rises along the baffle with the material, and in this process, the tension reset spring will have a tension spring force; when the chassis descends after the feeding is completed, the baffle will be reset under the action of the spring force.

[0024] A flush infrared sensor is arranged on the inner side of the preheating rack.

[0025] When it is necessary to transfer the semi-finished license plate in the preheating rack to the supporting tray, the vertical screw mechanism, under the action of the flush infrared sensor, controls the chassis of the supporting tray to move to a state flush with the preheating rack, and the cylinder drives the push plate to work, pushing the semi-finished license plate on the preheating rack to the supporting tray, completing the transfer of the semi-finished license plate.
