DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Reference Figures 1 to 6 As shown, the present invention provides a temperature equalization system for an electric heating press machine based on multi-zone heating, comprising

[0035] Support frame;

[0036] A plurality of pressing modules are arranged in an array at the bottom of the support frame, and the top of the pressing module is used to place the plate to be heated and pressed;

[0037] A temperature regulating mechanism is arranged inside the lower pressing module, and is used to heat the plate to be heated and pressed during pressing and to adjust the heating temperature;

[0038] An adjustable positioning mechanism is arranged at the top of the lower pressing module, and is used to position and fix the plates to be heated and pressed of different sizes;

[0039] An upper pressure module is arranged above the lower pressure module;

[0040] The driving mechanism is arranged at the top of the support frame, and the upper pressing module is fixedly arranged at the bottom of the driving mechanism. The driving mechanism is used to adjust the position of the upper pressing module in the horizontal plane so that the upper pressing module corresponds to any lower pressing module up and down and heats and presses the plate to be heated and pressed.

[0041] By setting the number of the lower pressing modules to a certain number, the heating and pressing of the wooden boards can be carried out in an uninterrupted cycle. The lower pressing modules stagger the operating steps to position, heat and press, maintain pressure, and unload the finished products of the wooden boards, which solves the problem of time waste caused by the frequent loading and unloading of a single lower pressing module, and greatly improves the production efficiency. The set temperature regulating mechanism can solve the problem that the heating temperature is not easy to control due to the traditional reliance on heating medium to heat the wooden boards, so that the heating temperature can be stably controlled and easily adjusted, ensuring the excellent quality of the finished products produced. The set adjustable positioning mechanism can enable the lower pressing module to stably support wooden boards of different sizes, thereby improving the application range of the system. The set driving mechanism can drive the upper pressing module to adjust to any position in the horizontal plane, so that the upper pressing module can reach directly above each lower pressing module to heat and press the wooden boards. The system of the present invention can not only ensure the high quality of the products, but also greatly improve the processing efficiency.

[0042] Furthermore, the lower pressing module includes a heating seat 4, which is fixedly arranged at the bottom end of the support frame, and a lower pressing plate 5 is fixedly connected to the top of the heating seat 4. Receiving grooves are arranged inside the heating seat 4 and the lower pressing plate 5. A yielding groove 35 is also opened on the lower pressing plate 5. The temperature regulating mechanism is arranged in the receiving groove of the heating seat 4, and the adjustable positioning mechanism is arranged in the receiving groove of the lower pressing plate 5. The movable end of the adjustable positioning mechanism is slidably arranged in the yielding groove 35.

[0044] Furthermore, the temperature regulating part includes a linear motor 19, which is fixedly arranged on the outer wall of the heating seat 4. The output end of the linear motor 19 slides through the outer wall of the heating seat 4 and is fixedly connected to a rack 20. The rack 20 is horizontally slidably connected to the inner wall of the accommodating groove of the heating seat 4. A gear 22 is rotatably sleeved on one end of the electric heating tube 21 close to the rack 20. The gear 22 is meshed with the rack 20. A rotating ring 23 is rotatably sleeved on the other end of the electric heating tube 21. The side walls where the gear 22 and the rotating ring 23 are close to each other are fixedly connected to connecting rods 26. The two connecting rods 26 are jointly fixedly connected to a heat reflector 25. The side wall where the heat reflector 25 is away from the electric heating tube 21 is fixedly connected to a heat insulation plate 24.

[0045] The electric heating tube 21 is energized to generate heat, and the generated heat heats the lower pressing plate 5 and the wooden board placed above it. When the heat generated by the electric heating tube 21 is constant and the heating temperature of the wooden board by the lower pressing plate 5 needs to be further increased, the linear motor 19 drives the rack 20 to move, and the rack 20 drives the gear 22 to rotate around the electric heating tube 21. During the rotation, the heat insulation plate 24 and the heat reflection plate 25 rotate to the bottom of the electric heating tube 21. The heat insulation function of the heat insulation plate 24 and the heat reflection function of the heat reflection plate 25 can radiate the electric heating tube 21 downward. The heat is reflected to the lower pressure plate 5 and the wooden board above, so as to further increase the heating temperature. When the heat generated by the electric heating tube 21 is constant and the heating temperature of the wooden board by the lower pressure plate 5 needs to be lowered, the linear motor 19 rotates in the reverse direction to drive the rack 20 to move in the reverse direction, and the insulation plate 24 and the heat reflection plate 25 are rotated to the top of the electric heating tube 21. The heat radiated upward by the electric heating tube 21 is still reflected to the bottom through the heat insulation function of the insulation plate 24 and the heat reflection function of the heat reflection plate 25, so as to achieve the purpose of lowering the heating temperature of the wooden board by the lower pressure plate 5.

[0046] Furthermore, the adjustable positioning mechanism includes a third motor 27, the third motor 27 is fixedly connected to the top wall of the accommodating groove of the lower pressure plate 5, the output shaft of the third motor 27 is fixedly connected to one end of the third lead screw 28, the other end of the third lead screw 28 is rotatably connected to the third lead screw seat 29, the third lead screw seat 29 is fixedly connected to the top wall of the accommodating groove of the lower pressure plate 5, the outer side wall of the third lead screw 28 is threadedly connected to a movable slider 30, the top end of the movable slider 30 is in sliding contact with the top wall of the accommodating groove of the lower pressure plate 5 and is fixedly connected to an elastic positioning part, and the elastic positioning part is slidably arranged in the yielding groove 35.

[0047] Furthermore, the elastic positioning portion includes a stopper 32, and two cavities 33 are defined at the bottom end of the stopper 32.

The limiting rod 31 is fixedly connected to the top of the movable slider 30, and the limiting rod 31 is in sliding contact with the inner wall of the cavity 33.

[0048] The position of the stopper 32 is adjusted according to the size of the wooden board to be pressed. During adjustment, the third motor 27 works to drive the third lead screw 28 to rotate, thereby driving the movable slider 30 to drive the stopper 32 to move left and right, so that the stopper 32 is in contact with the side edge of the wooden board. The four stoppers 32 are all in contact with the side edges of the wooden board to achieve the positioning of the wooden board. Then the wooden board can be pressed by the upper pressing module. During the pressing process, the overall thickness of the template will be reduced, resulting in the top position of the stopper 32 being higher than the top position of the wooden board, causing downward interference with the upper pressing module. To address this problem, a cavity 33 is provided inside the stopper 32, and a spring 34 is provided in the cavity 33. The spring 34 can adjust the height position of the stopper 32 by its own elasticity. When the upper pressing module contacts the top of the stopper 32 and continues to apply pressure to descend, the spring 34 can be compressed to lower the height of the stopper 32 to ensure that the stopper 32 does not interfere with the descending action of the upper pressing module.

[0049] Furthermore, the driving mechanism includes a first motor 6, which is fixedly connected to one end of the top of the support frame, and the output shaft of the first motor 6 is fixedly connected to one end of the first lead screw 7, and the other end of the first lead screw 7 is rotatably connected to the support frame. The outer wall of the first lead screw 7 is threadedly connected to a first lead screw slider 8, and the other end of the top of the support frame is fixedly connected to a first light rod 9, the first light rod 9 is parallel to the first lead screw 7 and is located in the same horizontal plane, and the outer wall of the first light rod 9 is slidably sleeved with a first light rod slider 10, the first lead screw slider 8 and the top of the first light rod slider 10 are jointly fixedly connected with a driving part, the driving part is perpendicular to the first lead screw 7 and the first light rod 9, the top of the driving part is in sliding contact with the top of the support frame, and the upper pressure module is fixedly arranged at the bottom of the driving part.

[0050] Furthermore, the driving part includes a second motor 11, which is fixedly connected to one end of the top of the first lead screw slider 8, and the output shaft of the second motor 11 is fixedly connected to one end of the second lead screw 12, and the other end of the second lead screw 12 is rotatably connected to a second lead screw seat 13, the second lead screw seat 13 is fixedly connected to one end of the top of the first light rod slider 10, and the other end of the top of the first lead screw slider 8 and the other end of the top of the first light rod slider 10 are both fixedly connected to a second light rod seat 15, and a second light rod 14 is fixedly connected between the two second light rod seats 15, the second light rod 14 is parallel to the second lead screw 12 and located in the same horizontal plane, the second lead screw 12 and the first lead screw 7 are perpendicular to each other, and the outer side wall of the second lead screw 12 is threadedly connected to one end of the driving slider 16, and the other end of the driving slider 16 is slidably sleeved on the outside of the second light rod 14, the top of the driving slider 16 is in sliding contact with the top of the support frame, and the upper pressure module is fixedly set at the bottom of the driving slider 16.

[0053] After the driving slider 16 moves to just above one of the lower pressing plates 5, the piston end of the hydraulic cylinder 17 extends to drive the upper pressing plate 18 to descend, and press the wooden board placed on the lower pressing plate 5. After the pressing is completed, the hydraulic cylinder 17 drives the upper pressing plate 18 to rise, and then drives the upper pressing plate 18 to the top of the other lower pressing plate 5 through the first screw 7 and the second screw 12, and continues to press the wooden board placed on the other lower pressing plate 5. During this process, the previous finished product that has been heated and pressed is transferred and unloaded by the staff, and then the wooden board to be pressed is replaced and waits for pressing.
