Description

Technical Field

[0001] The present invention relates to the technical field of UV paint drying and curing, and specifically relates to an energy-saving ultraviolet dryer for the UV paint surface of SPC wall panels. Background Art

[0002] In order to improve the decoration of SPC wall panels, a transfer film printed with a pattern needs to be fixed to the surface of the board using a hot press. Then a UV coating is applied, and then a drying device is used for photocuring treatment. When the drying device operates, heat is generated. If the heat accumulates and causes the temperature of the parts to be too high, it will not only pose a safety hazard, but also cause situations such as part deformation, affecting the operation stability of the device. Therefore, a cooling mechanism or a heat exchange mechanism is usually required to handle the heat. However, the heat exchange equipment will generate losses during operation and needs to be maintained regularly. However, the disassembly and assembly of the existing heat exchange equipment are too complicated, resulting in difficult maintenance.

[0003] For this reason, the Chinese patent with the authorization announcement number CN218627845U discloses an air-type heat exchanger for drying equipment. The heat exchanger body is fixed to the connecting frame by inserting elastic protrusions into the jacks inside the front and rear connecting vertical plates of the connecting frame. When using the air-type heat exchanger for drying equipment, first fix the connecting frame inside the drying equipment through the connecting holes and bolts, and then insert the heat exchanger body into the jacks inside the front and rear connecting vertical plates of the connecting frame through the elastic protrusions, so as to realize the fixation of the heat exchanger body and the connecting frame. Through the setting of the connecting frame, when using the air-type heat exchanger for drying equipment, the disassembly and repair of the air-type heat exchanger for drying equipment become very convenient, enabling the air-type heat exchanger for drying equipment to be better used, thereby improving the use performance of the air-type heat exchanger for drying equipment.

[0004] However, when using the heat exchanger for temperature control, a large amount of waste heat is still discharged into the air. If the waste heat is not utilized, it will not only increase the temperature of the working environment, but also cause the service life of a large number of parts to be significantly reduced under high temperature for a long time, resulting in a large amount of cost loss, and it is easy to cause safety accidents.

[0016] The beneficial effects of the present invention compared with the prior art are as follows: 1. The present invention realizes the function of preheating the board with the heat generated during the drying process through a conveyor, a drying oven, a heat exchanger, a preheating box and a diversion mechanism. When the UV curing lamp group in the drying oven works, waste heat is generated. The hot air flow in the drying oven is collected through the diversion mechanism, and the temperature of the hot air flow is adjusted through the heat exchanger. The heat in the hot air flow is used to preheat the board, eliminate the thermal stress of the board, reduce the deformation amount of the board, and ensure the coating uniformity and curing quality under high-speed production.

[0017] 2. The present invention realizes the function of collecting the heat flow at multiple positions in the drying oven and centrally inputting it into the heat exchanger through the diversion bin and the buffer bin. Collecting the heat flow at multiple positions can improve the heat flow collection efficiency and avoid the situation of too large local temperature difference in the drying oven. The air flow in the diversion bin enters the buffer bin through the docking groove, and then enters the heat exchanger from the buffer bin through a pipeline. Through the arrangement of multiple diversion bins, the uniformity of air flow attraction can be improved, the heat can be attracted with the highest efficiency, and the situation of too large local temperature difference caused by heat loss in the drying oven can be avoided.

Through the closing function of the closing mechanism, the operator can disassemble the diversion bin during the working process. When the diversion bin is disassembled, the closing can timely close the installation groove and the docking groove to avoid heat leakage. When installing the diversion bin, the operator inserts the diversion bin into the installation groove along the guide seat. When the diversion bin is inserted and matched with the installation groove, through the extrusion action of the diversion bin, the closing of the installation groove and the docking groove by the closing mechanism is released, and the diversion bin, the drying oven and the heat exchanger are connected, achieving the effect of preheating the board with waste heat.

Detailed implementation manners

[0030] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0031] Refer to Figures 1-3 : A UV paint surface energy-saving ultraviolet dryer for SPC wall panels, comprising a conveyor 1, a drying oven 11, a heat exchanger 12 and a preheating box 13 are provided on the conveyor 1; the heat exchanger 12 is communicated with the drying oven 11 and the preheating box 13 through pipelines; a flow guiding mechanism 2 for guiding the heat flow is provided on the drying oven 11; in the working state, the heat flow in the drying oven 11 is guided by the flow guiding mechanism 2 to enter the heat exchanger 12 through the pipeline, and after the heat exchanger 12 adjusts the temperature of the heat flow, the heat flow is sent into the preheating box 13 through the pipeline.

[0032] The present invention realizes the function of preheating the board with the heat generated during the drying process through the conveyor 1, the drying oven 11, the heat exchanger 12, the preheating oven 13 and the diversion mechanism 2. When the UV curing lamp group in the drying oven 11 works, waste heat is generated. The diversion mechanism 2 collects the hot air flow in the drying oven 11, and adjusts the temperature of the hot air flow through the heat exchanger 12. The heat in the hot air flow is used to preheat the board, eliminate the thermal stress of the board, reduce the deformation amount of the board, and ensure the coating uniformity and curing quality under high-speed production. It solves the problem that a large amount of waste heat is discharged during the operation of traditional drying equipment. A plurality of UV curing lamps are provided in the drying oven 11, and the heat exchanger 12 is a plate heat exchanger. In the working state, the surface of the board is first dusted and the static electricity is eliminated, and then UV coating is carried out. Then the board is transported by the conveyor 1, and the board passes through the preheating oven 13 and the drying oven 11 in sequence on the conveyor 1. The board is preheated in the preheating oven 13. When the board enters the drying oven 11, it is subjected to photocuring treatment by the UV curing lamps in the drying oven 11. During this process, the hot air flow in the drying oven 11 is introduced into the heat exchanger 12 through the diversion mechanism 2. After the temperature of the hot air flow is adjusted by the heat exchanger 12, the hot air flow is sent into the preheating oven 13 to preheat the board. By reusing the waste heat, the heat utilization rate is improved, the energy consumption is greatly reduced, and the effect of energy conservation and emission reduction is achieved. After the board is dried, its glossiness is detected, the adhesion is tested, and the hardness is detected. After passing the inspection, the board is registered and stored in the warehouse.

[0033] Refer to Figures 1-3 : The diversion mechanism 2 includes a diversion bin 21 and a buffer bin 22; there are at least two diversion bins 21, and the diversion bins 21 are arranged on the drying oven 11; the buffer bin 22 is arranged on the diversion bin 21, a docking groove 221 is opened on the buffer bin 22, and the diversion bin 21 is communicated with the buffer bin 22 through the docking groove 221.

[0034] The present invention realizes the function of collecting the heat flow at multiple positions in the drying oven 11 and centrally inputting it into the heat exchanger 12 through the diversion bin 21 and the buffer bin 22. By collecting the heat flow at multiple positions, the heat flow collection efficiency can be improved, and at the same time, the situation of too large local temperature difference in the drying oven 11 can be avoided. A plurality of diversion bins 21 are spaced apart and evenly distributed on the drying oven 11. The buffer bin 22 is communicated with the heat exchanger 12 through a pipeline, and an air pump for controlling the air flow is provided on the pipeline of the heat exchanger 12.

[0035] In the working state, a negative pressure is formed at the diversion chamber 21 through an air pump, thereby attracting air flow into the diversion chamber 21. The air flow in the diversion chamber 21 enters the buffer chamber 22 through the docking groove 221, and then enters the heat exchanger 12 from the buffer chamber 22 through a pipeline. Through the arrangement of multiple diversion chambers 21, the uniformity of air flow attraction can be improved, and while attracting heat with the maximum efficiency, the situation of excessive local temperature difference due to heat loss in the drying oven 11 can be avoided.

[0036] Refer to Figure 1 and Figure 3 : A clamping mechanism 3 and a closing mechanism 4 are provided on the drying oven 11; an installation groove 111 for accommodating the diversion chamber 21 is formed on the drying oven 11. When the diversion chamber 21 is inserted and matched with the installation groove 111, the diversion chamber 21 is connected to the drying oven 11 through the clamping mechanism 3; when the diversion chamber 21 is separated from the installation groove 111, the closing mechanism 4 closes the installation groove 111 and the docking groove 221.

[0037] The present invention realizes the function of disassembling and assembling the diversion chamber 21 during the working process through the clamping mechanism 3 and the closing mechanism 4. Through the closing effect of the closing mechanism 4, the operator can disassemble the diversion chamber 21 during the working process. When the diversion chamber 21 is removed, the closing mechanism 4 can timely close the installation groove 111 and the docking groove 221 to avoid heat leakage. A guiding seat 112 for guiding the disassembly and assembly of the diversion chamber 21 is provided on the drying oven 11. When installing the diversion chamber 21, the operator inserts the diversion chamber 21 into the installation groove 111 along the guiding seat 112. When the diversion chamber 21 is inserted and matched with the installation groove 111, through the extrusion effect of the diversion chamber 21, the closing of the installation groove 111 and the docking groove 221 by the closing mechanism 4 is released, connecting the diversion chamber 21, the drying oven 11 and the heat exchanger 12, achieving the effect of preheating the plate by using waste heat.

[0038] Refer to Figure 1 、 Figure 3 and Figure 4 : The clamping mechanism 3 includes a clamping component 31 and a control component 32; when the diversion chamber 21 is inserted and matched with the installation groove 111, the clamping component 31 restricts the movement of the diversion chamber 21; the control component 32 is used to release the movement restriction of the clamping component 31 on the diversion chamber 21.

[0039] The present invention realizes the function of quickly connecting the diversion bin 21 and the drying box 11 through the clamping component 31 and the control component 32, achieving the effect of quickly disassembling and assembling the diversion bin 21. When maintaining the diversion bin 21, the operator first releases the movement restriction of the diversion bin 21 by the clamping component 31 through the control component 32. Then, the diversion bin 21 is removed, and the diversion bin 21 is cleaned and maintained. After the maintenance is completed, the diversion bin 21 is inserted into the installation groove 111 along the guiding seat 112. When the diversion bin 21 is inserted and matched with the installation groove 111, the clamping component 31 connects the drying box 11 and the diversion bin 21, restricting the movement of the diversion bin 21. During this process, through the extrusion action of the diversion bin 21, the closing mechanism 4 releases the closing restriction on the installation groove 111 and the docking groove 221.

[0040] Refer to Figure 3 and Figure 4 : The closing mechanism 4 includes a first closing component 41 and a second closing component 42; the first closing component 41 is arranged on the drying box 11, and the second closing component 42 is arranged on the buffer bin 22; the first closing component 41 and the second closing component 42 are respectively used to close the installation groove 111 and the docking groove 221.

[0041] The present invention realizes the function of automatically closing the installation groove 111 and the docking groove 221 through the first closing component 41 and the second closing component 42, achieving the effect of timely closing the channel and reducing heat loss after disassembling the diversion bin 21. Through the first closing component 41 and the second closing component 42 respectively arranged on the drying box 11 and the buffer bin 22, the installation groove 111 and the docking groove 221 can be automatically closed after the diversion bin 21 is disassembled.

[0042] Refer to Figures 4-7 : The clamping component 31 includes a first mounting seat 311, a clamping block 312 and a first elastic member 313; the first mounting seat 311 is arranged on the drying box 11; the clamping block 312 is slidably mounted on the first mounting seat 311; both ends of the first elastic member 313 are connected to the clamping block 312 and the first mounting seat 311 respectively; a second mounting seat 211 is provided on the diversion bin 21, and a clamping groove 2111 matching with the clamping block 312 is formed on the second mounting seat 211.

[0043] The present invention realizes the function of connecting the guide chamber 21 and the drying box 11 through the first mounting seat 311, the clamping block 312, the first elastic member 313 and the second mounting seat 211. The clamping block 312 is provided with an inclined surface, and the first mounting seat 311 is provided with a receiving groove for receiving the clamping block 312. When installing the guide chamber 21, the guide chamber 21 is pushed into the mounting groove 111 along the guide seat 112, and the second mounting seat 211 on the guide chamber 21 contacts the clamping block 312, and the inclined surface of the clamping block 312 is squeezed by the second mounting seat 211, and the first elastic member 313 is compressed under the pressure, and then the clamping block 312 is pushed into the receiving groove of the first mounting seat 311. Then continue to push the guide chamber 21 to allow the second mounting seat 211 to pass through the block 312. When the slot 2111 on the second mounting seat 211 is aligned with the block 312, the second mounting seat 211 no longer pushes the block 312. The block 312 is plugged into and matched with the slot 2111 under the elastic force of the first elastic member 313.

[0044] Reference Figures 4-7 : The control component 32 includes a bracket 321, a wedge block 322, a push plate 323 and a second elastic member 324; the bracket 321 is connected to the block 312, and the bracket 321 is slidably matched with the first mounting seat 311; the wedge block 322 is slidably installed on the first mounting seat 311, and the wedge block 322 is slidably matched with the bracket 321; the push plate 323 is connected to the wedge block 322; the two ends of the second elastic member 324 are respectively connected to the push plate 323 and the first mounting seat 311.

[0045] The present invention realizes the function of controlling the movement of the card block 312 through the bracket 321, the wedge block 322, the push plate 323 and the second elastic member 324, so as to achieve the effect of removing the movement restriction of the guide bin 21 by the card connection. The bracket 321 has a straight groove, and the wedge block 322 is plugged and matched with the bracket 321 through the straight groove, and the inclined surface of the wedge block 322 is slidably matched with the bracket 321. When disassembling the guide bin 21, the operator presses the push plate 323, and the second elastic member 324 is compressed under the pressure, and then the wedge block 322 is driven to move downward through the push plate 323. The wedge block 322 squeezes the bracket 321 connected to the card block 312 during the downward movement, thereby pushing the bracket 321 to move. The bracket 321 is slidably matched with the first mounting seat 311, and the movement of the bracket 321 is guided by the first mounting seat 311, so that the bracket 321 stably drives the card block 312 to move when moving, and the first elastic member 313 is compressed under the pressure. After the clamping block 312 is separated from the clamping slot 2111 , the restriction on the movement of the flow guide bin 21 by the clamping assembly 31 is released, and the operator removes the flow guide bin 21 from the installation slot 111 .

[0046] Reference Figures 3-5: The first closing component 41 includes a first closing plate 411, a guide rod 412, and a third elastic member 413; the guide rod 412 is connected to the first closing plate 411, and the guide rod 412 is slidably engaged with the drying box 11; a limiting piece 4121 is connected to the end of the guide rod 412 away from the first closing plate 411; both ends of the third elastic member 413 are respectively connected to the limiting piece 4121 and the drying box 11; when the diversion bin 21 is separated from the installation groove 111, the first closing plate 411 abuts against the drying box 11 under the elastic force of the third elastic member 413 and blocks the installation groove 111.

[0047] The present invention realizes the function of closing the installation groove 111 through the first closing plate 411, the guide rod 412, and the third elastic member 413. After the diversion bin 21 is removed, the limiting piece 4121 moves upward under the elastic force of the third elastic member 413, and the limiting piece 4121 pulls the first closing plate 411 to move synchronously through the guide rod 412 until the first closing plate 411 abuts against the drying box 11, and the first closing plate 411 completely blocks the installation groove 111. When installing the diversion bin 21, the operator inserts the diversion bin 21 along the guide seat 112. After the diversion bin 21 contacts the first closing plate 411, the first closing plate 411 is pushed to move. The third elastic member 413 is compressed under the thrust, and after the first closing plate 411 is separated from the drying box 11, the channel between the diversion bin 21 and the drying box 11 is opened, so that the heat flow can enter the diversion bin 21 through the installation groove 111. When disassembling the diversion bin 21, the operator pushes the push plate 323, and the control assembly 32 releases the movement restriction of the clamping assembly 31 on the diversion bin 21. Then the first closing plate 411 moves upward under the elastic force of the third elastic member 413, and then the diversion bin 21 is pushed to move upward through the first closing plate 411, which is convenient for the operator to remove the diversion bin 21 and further improves the disassembly portability of the diversion bin 21.

[0048] Refer to Figure 4 、 Figures 8-10 : The second closing component 42 includes a second closing plate 421, a third mounting seat 422, a movable rod 423, and a fourth elastic member 424; the second closing plate 421 is rotatably arranged on the buffer bin 22, and the second closing plate 421 is connected to the buffer bin 22 through a torsion spring; the third mounting seat 422 is arranged on the diversion bin 21, and the movable rod 423 is slidably mounted on the third mounting seat 422; both ends of the fourth elastic member 424 are respectively connected to the third mounting seat 422 and the movable rod 423.

[0049] The present invention realizes the function of closing the docking groove 221 through the second closing plate 421, the third mounting seat 422, the movable rod 423 and the fourth elastic member 424. When the diversion chamber 21 and the mounting groove 111 are in a separated state, the second closing plate 421 forms a rigid contact with the side wall of the buffer chamber 22 under the elastic reset action of the torsion spring, realizing the full-section closing of the docking groove 221. During the assembly process of the diversion chamber 21, the diversion chamber 21 is guided to axially advance along the mounting groove 111 through the guide seat 112. When the guide member reaches the preset installation position, the movable rod 423 arranged in the third mounting seat 422 generates a displacement under the axial driving force of the fourth elastic member 424, and this displacement amount is converted through the kinematic pair to form a tangential thrust on the second closing plate 421. Under the action of this thrust, the second closing plate 421 rotates, releasing the closed state of the docking groove 221 and establishing a heat conduction channel between the diversion chamber 21 and the buffer chamber 22. So that the heat flow in the diversion chamber 21 can enter the buffer chamber 22 through the docking groove 221.

[0050] Refer to Figures 8-10 : An arc-shaped block 4231 is connected to the end of the movable rod 423 away from the third mounting seat 422.

[0051] The present invention realizes the function of facilitating the installation of the diversion chamber 21 through the arc-shaped block 4231. Since the movable rod 423 will be in an extended state under the elastic force of the fourth elastic member 424, when installing the diversion chamber 21, in order to prevent the movable rod 423 from abutting against the outer wall of the buffer chamber 22 and hindering the installation of the diversion chamber 21. The operator needs to first push the movable rod 423 into the third mounting seat 422 during the installation process, which is extremely cumbersome. Therefore, a cylindrical arc-shaped block 4231 is provided at the end of the movable rod 423. When installing the diversion chamber 21, the arc-shaped block 4231 at the end of the movable rod 423 abuts against the outer wall of the buffer chamber 22. Guided by the arc surface of the arc-shaped block 4231, the arc-shaped block 4231 will be subjected to the extrusion of the outer wall of the buffer chamber 22, and the fourth elastic member 424 is compressed under the extrusion, thereby achieving the effect of automatically controlling the contraction of the movable rod 423 and preventing the movable rod 423 from affecting the installation of the diversion chamber 21.

[0052] The above embodiments only represent one or several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but should not be construed as limiting the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
