DETAILED DESCRIPTION

[0029] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0030] Referring to Figures 1-4The utility model provides a kind of drying device for synthetic resin manufacturing, including drying frame 1, drying unit 2, vacuum unit 3, drying unit 2 is provided with drying cavity for storing synthetic resin (mainly for synthetic resin particles and synthetic resin product), vacuum unit 3 is used to remove air in drying cavity, so that drying cavity is in vacuum state, reduce the boiling point of moisture in synthetic resin in drying cavity, to let the water in synthetic resin can be quickly discharged, reach the purpose of let synthetic resin dry quickly, the input of vacuum unit 3, reduce the boiling point of water, reduce the heat input required for drying synthetic resin in drying cavity, also reduce the energy input of device overall, reach the effect of reducing energy consumption, energy saving.

[0031] When vacuum unit 3 works, it will remove the air in the drying cavity of drying unit 2, so that the drying cavity is in a vacuum state. Then, by heating the synthetic resin in the drying cavity of drying unit 2, the synthetic resin is quickly dried. In the drying process, to avoid risks, workers need not to touch the components in drying unit 2 and vacuum unit 3. Currently, a protective door is usually arranged on drying frame 1 to open and close the opening on drying frame 1. The existing protective door is mostly controlled by a single button when opening. When closing, some workers may carelessly place their hands inside drying frame 1, which may cause the protective door to pinch the workers when closing. Moreover, if power failure occurs during the opening process of the protective door, the components that push the protective door to move will lose power, and the powerless protective door may directly fall, causing damage to drying frame 1 and the protective door. To solve the above problems, a baffle 4 is arranged in drying frame 1.

[0032] Specifically, baffle 4 can only move up and down relative to drying frame 1. Baffle 4 is connected with a support 5 at the bottom. Support 5 is hinged with an extension rod 6. The other end of extension rod 6 is connected with a lower mounting seat 7. Lower mounting seat 7 is fixedly installed in drying frame 1. Extension rod 6 is provided with two, and the output ends of the two extension rods 6 are respectively connected with two supports 5. The two supports 5 are parallelly distributed at the bottom of baffle 4.

[0033] More specifically, baffle 4 is provided with a mounting groove 401. A protective plate 8 is inserted into mounting groove 401. Protective plate 8 is connected with a spring 404. Protective plate 8 has an extended state and a contracted state. Drying frame 1 is provided with a blocking piece 9. Blocking piece 9 is provided with a plurality of blocking grooves. When protective plate 8 is in the extended state, the blocking grooves block the passage of protective plate 8 moving downward.

[0034] During the upward movement of baffle 4, protective plate 8 is converted between each blocking groove under the action of spring 404. After protective plate 8 is inserted into a blocking groove, it cannot move downward under the action of the elasticity of spring 404. Even if extension rod 6 loses power due to power failure, protective plate 8 and baffle 4 will not fall down.

[0035] It should be noted that the guard plate 8 includes a trapezoidal plate 801, which is arranged in a right trapezoidal shape and provided with an inclined edge. In the stretched state, the inclined edge of the trapezoidal plate 801 is aligned with the outer wall of the blocking groove. The top and bottom of the trapezoidal plate 801 are respectively provided with an upper guide block 802 and a lower guide block 803. The baffle 4 is provided with an upper guide groove 402 and a lower guide groove 403 at the position corresponding to the installation groove 401. The upper guide block 802 cooperates with the upper guide groove 402, and the lower guide block 803 cooperates with the lower guide groove 403. A magnetic adsorption unit 405 is arranged in the installation groove 401. When the magnetic adsorption unit 405 is started, it can move the trapezoidal plate 801 to the inside of the installation groove 401 by magnetic force, so that the guard plate 8 is converted to the retracted state. In the case of power failure, the magnetic adsorption unit 405 is powered off, and the trapezoidal plate 801 loses the magnetic force and is converted to the stretched state under the action of the spring 404, so that the baffle 4 is clamped in the blocking groove, avoiding the baffle 4 from directly falling down when the telescopic rod 6 loses power.

[0036] Specifically, the blocking piece 9 includes a blocking frame 901 and a protection block 902. The blocking groove is arranged inside the protection block 902. A plurality of protection blocks 902 are installed on the blocking frame 901 at equal intervals. The blocking piece 9 is provided with two, and the two blocking pieces 9 are respectively located on both sides of the baffle 4.

[0037] In order to detect the human hand, a detection groove is arranged on the top of the baffle 4. A laser detection unit 10 (including a laser emitter and a laser receiver, which are respectively installed on the baffle 4 and the drying frame 1) is arranged in the detection groove. The laser detection unit 10 detects whether there is a person by laser. It is connected to the controller. If the laser is blocked, it means that there is an obstacle in the direction of the baffle 4. At this time, the telescopic rod 6 needs to be turned off so that it cannot continue to move, avoiding injury to the human body.

[0038] Further, two manual pressing buttons 13 are arranged on the drying frame 1. The telescopic rod 6 is connected with a control switch for controlling the switch. The control switch is connected in series with the two manual pressing buttons 13. It also needs to be connected with the controller and the power supply. In this way, only when the two manual pressing buttons 13 are pressed, the telescopic rod 6 can be started. There is a certain distance between the two manual pressing buttons 13, which needs to be closed by both hands. In this way, the staff can only close the baffle 4 by both hands, which can avoid the staff's palms from being left in the drying frame 1 when the baffle 4 is closed.

[0039] The bottom of the drying frame 1 is provided with four casters 12 with brake function, and the casters 12 are provided with bases 11 on the sides for adjusting the height of the drying frame 1, and the side edges of the drying frame 1 are provided with net plates 14 for avoiding the staff from entering from other directions, and the staff can only feed and discharge the synthetic resin from the baffle 4.

[0040] Working principle:

[0041] The vacuumizing unit 3 is used for drawing away the air in the drying cavity, so that the drying cavity is in a vacuum state, the boiling point of the moisture in the synthetic resin in the drying cavity is reduced, and then the water in the synthetic resin can be quickly discharged, so that the purpose of quickly drying the synthetic resin is achieved, the input of the vacuumizing unit 3 reduces the boiling point of the water, reduces the heat input required for drying the synthetic resin in the drying cavity, and also reduces the overall energy input of the device, so that the effect of reducing energy consumption and saving energy is achieved.

[0042] During the upward movement of the baffle 4, the protection plate 8 is converted between the blocking grooves under the action of the spring 404, and after the protection plate 8 is inserted into the blocking groove, it cannot be moved downward under the action of the elastic force of the spring 404, even if the telescopic rod 6 loses power due to power failure, the protection plate 8 and the baffle 4 will not fall down.

[0043] The drying frame 1 is provided with two manual pressing buttons 13, and the telescopic rod 6 is connected with a control switch for controlling the switch, and the control switch is connected with the two manual pressing buttons 13 in series, and also needs to be connected with a controller and a power supply, so that only when the two manual pressing buttons 13 are pressed, the telescopic rod 6 can be started, and there is a certain distance between the two manual pressing buttons 13, which needs to be closed by two hands, so that the staff can only close the baffle 4 by two hands, which can avoid the staff leaving part of the palm in the drying frame 1 when the baffle 4 is closed.

[0044] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
