[0028] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0029] In view of the defects existing in the prior art, the present invention proposes a double-beam fixed-thickness automatic feeding and unloading corner plate hot press, which is used to manufacture corner plates. The hot pressing unit 4 provides appropriate pressure and heat to promote the curing and molding of the glue inside the product, shortening the product molding time and improving production efficiency.

[0030] The hot pressing unit 4 includes a corner block 43, which is detachably connected to facilitate replacement with different models. The corner block 43 includes a right-angle type and a rounded-angle type. The right-angle type is used to produce right-angle corner panels, and the rounded-angle type is used to produce rounded corner panels, which increases the types of corner panels that can be produced, expands the production range, and improves practicality.

[0031] The feeding mechanism, the corner plate hot press and the discharging mechanism constitute a hot processing system. The feeding mechanism realizes automatic loading of raw materials, and the discharging mechanism realizes automatic discharging of finished products. The feeding mechanism, the discharging mechanism and the corner plate hot press cooperate to realize the automation of feeding, pressing and discharging, thereby reducing the labor intensity of manual operations.

[0032] Embodiment 1:

[0033] like Figure 1 and Figure 2 As shown, a double-beam fixed-thickness automatic feeding and unloading corner plate hot press machine comprises an upper crossbeam 1, a lower crossbeam 2, a driving unit 3 and a hot pressing unit 4;

[0034] The upper crossbeam 1 and the lower crossbeam 2 are arranged opposite to each other, and the driving unit 3 connects the upper crossbeam 1 and the lower crossbeam 2 and can drive the upper crossbeam 1 to rise and fall;

[0035] There are two heat pressing units 4, and the two heat pressing units 4 are respectively arranged on the upper crossbeam 1 and the lower crossbeam 2;

[0036] Each hot pressing unit 4 includes a first hot pressing plate 41, a second hot pressing plate 42 and a corner block 43. The first hot pressing plate 41 and the second hot pressing plate 42 are both inclined and connected to the upper cross beam 1 or the lower cross beam 2. The ends of the first hot pressing plate 41 and the second hot pressing plate 42 are connected through the corner block 43. The corner block 43 is detachably connected to the upper cross beam 1 or the lower cross beam 2, and the processing surface of the corner block 43 in contact with the corner plate is configured as a right angle or a rounded angle.

[0037] Correspondingly, the bottom surface of the upper crossbeam 1 and the top surface of the lower crossbeam 2 are both configured as V-shaped surfaces; one of the two corner blocks 43 is configured as a negative angle, and the other is configured as a positive angle adapted to the negative angle.

[0038] The upper crossbeam 1 and the lower crossbeam 2 are arranged opposite to each other and form a double-beam structure, with a certain gap between them, which is used to place hot-pressed products; the upper crossbeam 1 and the lower crossbeam 2 are connected by a driving unit 3, which can drive the upper crossbeam 1 to rise and fall while playing a connecting role, and the lower crossbeam 2 remains relatively still. Specifically, the upper crossbeam 1 descends to reduce the gap, and at the same time, pressure is applied to the product to process the product, and the upper crossbeam 1 moves up to expand the gap, so as to facilitate the feeding of unprocessed products and the discharging of processed products. The lower crossbeam 2 is fixed on the site by any suitable connection method, which will not be repeated here.

[0039] In view of the fact that the processed product is a corner plate, the hot pressing unit 4 is divided into a first hot pressing plate 41 and a second hot pressing plate 42, both of which are inclined and intersect at a corner block 43. Specifically, the angle between the first hot pressing plate 41 and the second hot pressing plate 42 can be configured as any suitable angle, including but not limited to 60 degrees, 90 degrees and 120 degrees. Accordingly, the upper crossbeam 1 and the lower crossbeam 2 are both configured as V-shaped surfaces to adapt to the shape of the corner plate to be processed.

[0040] Preferably, when producing corner panels of different corner types, it is sufficient to replace the corner block 43 of the appropriate type. Therefore, the corner block 43 adopts a detachable connection method, which also reduces the workload of disassembling and assembling the hot pressing unit 4 and reduces the labor intensity.

[0041] During operation, the drive unit 3 lifts the upper beam 1, and the unprocessed product is conveyed into the gap. The drive unit 3 is activated to move the upper beam 1 downward and press the product. The hot pressing unit 4 is activated at the same time to heat the product, and the product is quickly formed under the pressure and high temperature. After the product processing is completed, the drive unit 3 lifts the upper beam 1 to loosen the product, and the processed product is sent out of the corner hot press machine, and the unprocessed product is conveyed into the corner plate hot press machine for the next hot pressing process.

[0042] Compared with the cold pressing process in the prior art, the hot pressing process is realized by heat supply by the hot pressing unit 4, which effectively shortens the pressing time from 3-6 hours to 1.5-10 minutes, greatly improves the production efficiency and solves the problem of long pressing time.

[0043] Preferably, two hot pressing units 4 are provided, and the two hot pressing units 4 are respectively arranged on the upper crossbeam 1 and the lower crossbeam 2. Based on the above design scheme, the number of hot pressing units 4 is increased, and the two hot pressing units 4 contact the upper and lower surfaces of the product at the same time, respectively, so that more heat is supplied to the product, the heat conduction area of ​​the product is larger, the product molding time is shortened, and the production efficiency is improved.

[0044] In a possible implementation, the hot pressing unit 4 includes a first heat insulating layer 44 and a second heat insulating layer 45, wherein the first heat insulating layer 44 is connected to the first hot pressing plate 41, and the second heat insulating layer 45 is connected to the second hot pressing plate 42. Based on the above design, the first heat insulating layer 44 and the second heat insulating layer 45 have the same functions and structures, and the first heat insulating layer 44 is used as an example for explanation. The first hot pressing plate 41 maintains a relatively high temperature during the pressing process, and the heat will not only be transferred to the product, but also to the upper beam 1 or the lower beam 2. The upper beam 1 or the lower beam 2 will be deformed at high temperature, which affects the product quality and the lifting and lowering of the upper beam 1, so the first heat insulating layer 44 is used for insulation.

[0045] The first heat insulating layer 44 reduces the heat transfer to the upper beam 1 or the lower beam 2, which not only protects the upper beam 1 or the lower beam 2, but also makes the heat of the first hot pressing plate 41 more concentrated on the product, so that the first hot pressing plate 41 works in a thermally balanced state, which helps to reduce energy consumption.

[0046] Regarding the setting of the first thermal insulation layer 44 and the second thermal insulation layer 45, specifically: for the hot pressing unit 4 fixed on the upper crossbeam 1, the first thermal insulation layer 44 is used to separate the first hot pressing platen 41 from the upper crossbeam 1, and the second thermal insulation layer 45 is used to separate the second hot pressing platen 42 from the upper crossbeam 1; for the hot pressing unit 4 fixed on the lower crossbeam 2, the first thermal insulation layer 44 is used to separate the first hot pressing platen 41 from the lower crossbeam 2, and the second thermal insulation layer 45 is used to separate the second hot pressing platen 42 from the lower crossbeam 2.

[0047] The insulation measure used in the prior art is a thermal insulation layer (including but not limited to wood boards and fiberboards), and the upper beam 1 is taken as an example for explanation: the thermal insulation layer has low thermal conductivity efficiency, but can still transfer heat. Given that the upper beam 1 has a certain thickness, the heat is gradually transferred from the part of the upper beam 1 that contacts the constant temperature insulation layer along the thickness direction of the upper beam 1. The upper beam 1 is heated unevenly along the thickness direction, which leads to thermal deformation of the upper beam 1.

[0048] Based on this, the first heat insulation layer 44 and the second heat insulation layer 45 are both heat-equalizing heat insulation layers, which include a number of spaced-apart bearing bars, and a heat-insulating space is formed between adjacent bearing bars. Among them, the bearing bars reduce the contact area between the first hot pressing plate 41 and the second hot pressing plate 42 and the upper crossbeam 1, and the heat transfer by heat conduction is reduced; the heat insulation space conducts heat through thermal convection, the heat conduction efficiency is reduced, and the heat is concentrated on the product; the two ends of the heat insulation space are connected to the outside world, so the air flows along the heat insulation space and forms a hot air flow, and the hot air flow flows along the upper crossbeam 1 and makes the upper crossbeam 1 heated more evenly, effectively solving the problem of thermal deformation of the upper crossbeam 1.

[0049] It is easy to understand that the bearing strip can be made of any suitable material on the basis of ensuring the compressive strength. The effect of the heat-dissipating insulation layer on the lower beam 2 is the same as that on the upper beam 1, which will not be described in detail here.

[0050] Optionally, the hot pressing unit 4 further includes a temperature control module, which is respectively connected to the first hot pressing plate 41 and the second hot pressing plate 42 in communication. The temperature control module is used to monitor and adjust the temperature of the first hot pressing plate 41 and the second hot pressing plate 42 in real time to ensure that the hot pressing temperature meets the process requirements. When the hot pressing unit 4 is provided on both the upper crossbeam 1 and the lower crossbeam 2, the temperature control module can synchronously control the temperature of the two hot pressing units 4, or asynchronously control them to meet the process requirements of products of different materials.

[0051] In a possible implementation, an anti-adhesive cloth and a tensioning device 6 thereof are provided on the upper crossbeam 1. Based on the above design scheme, the product includes glue for bonding, and pressure is provided by the upper crossbeam 1 during pressing, and heat is provided by the hot pressing unit 4 to solidify the glue and play a bonding role. However, when the amount of glue applied is large, the phenomenon of glue overflow is prone to occur, and the overflowed glue will solidify into blocks and adhere to the hot pressing unit 4. When the next product is processed, the glue block is pressed by the hot pressing unit 4, causing defects on the surface of the product. Therefore, the glue block on the hot pressing unit 4 is removed by the anti-adhesive cloth and the tensioning device 6 to ensure the surface quality of the product, improve the yield of production, and reduce the waste of products.

[0052] In a possible implementation, a conveying mechanism 7 for moving materials is provided on the lower crossbeam 2. Based on the above design, the conveying mechanism 7 is used to drive the products to move on the corner plate hot press so that the products are evenly distributed in the format without the need for workers to pull. Correspondingly, the upper crossbeam 1, the lower crossbeam 2, the hot pressing unit 4 and the conveying mechanism 7 are all provided with a friction-reducing layer in contact with the raw materials. The friction-reducing layer is made by friction-reducing measures such as air flotation, oil flotation, magnetic flotation or coating with a friction-reducing coating to reduce the friction coefficient and reduce the driving force required to move the raw materials.

[0053] like Figure 1 As shown, the driving unit 3 includes an upper support 31, a rod body 32, a driving part 33 and a lower support 34 which are connected in sequence from top to bottom. The upper support 31 is fixedly connected to the upper beam 1, the rod body 32 can guide the lifting direction of the upper beam 1, the lower support 34 is fixedly connected to the lower beam 2, and the driving part 33 is selected from an oil cylinder, a lift or an electric cylinder, and the oil cylinder and the lift are connected to a constant pressure hydraulic station.

[0054] Based on the above design, the driving part 33 can drive the rod body 32 to rise and fall, and the upper crossbeam 1 is driven to rise and fall by the rising and falling of the rod body 32, thereby providing a pressing force for pressing the product, and at the same time, the rod body 32 plays a guiding role. At the same time, the driving part 33, the upper crossbeam 1 and the lower crossbeam 2 form a closed force system, and the magnitude of the pressing force can be accurately adjusted according to the process requirements, so that the bonding quality of the product is better, which helps to improve the quality of the product.

[0055] In addition, the driving part 33 has a variety of options, including but not limited to oil cylinders, lifters and electric cylinders, and any other suitable commercially available equipment can be selected according to actual processing conditions. At the same time, the oil cylinder and lifter are connected to a constant pressure hydraulic station, which ensures that the pressing force is constant, avoiding the problem of reduced pressing quality due to fluctuations in the pressing force.

[0056] like Figure 2As shown, a set of driving groups are respectively arranged on both sides of the upper crossbeam 1, each driving group includes a plurality of driving units 3 arranged at intervals, and a guide device 8 is arranged between adjacent driving units 3. Based on the above design scheme, the driving units 3 are arranged symmetrically at multiple points, and the pressing force acts evenly on the product, avoiding the situation of inconsistent product thickness, which helps to improve the qualified rate of product processing.

[0057] At the same time, the guide device 8 is used to guide the lifting of the upper beam 1, thereby improving the lifting accuracy of the upper beam 1. The guide device 8 also enhances the stability of the lower beam 2 during the pressurization process, thereby ensuring the accuracy of product pressing. It is easy to understand that the guide device 8 can be any suitable commercially available model.

[0058] In a possible implementation, a stopper 9 is provided between the upper crossbeam 1 and the lower crossbeam 2, and the stopper 9 is used to control the thickness of the corner plate. Based on the above design, the lower limit position of the upper crossbeam 1 is controlled by the stopper 9, which can achieve the purpose of controlling the thickness of the corner plate on the one hand, and avoid the situation where the product is damaged due to excessive pressing force on the other hand. It is easy to understand that the stopper 9 can be any suitable commercially available model.

[0059] Optionally, the corner plate hot press machine also includes a control module and a communication module, and the control module is connected to the drive unit 3, the transmission mechanism 7 and the temperature control module through the communication module. Based on this, the control module is used to realize the automatic operation of the corner plate hot press machine, and the closed-loop control of time, temperature and pressure is realized. When there is a deviation between the measured value and the set value of any parameter, there will be a corresponding prompt or the execution of the corresponding deviation correction program. When all parameters meet the set values, the corner plate hot press machine will automatically execute the actions of feeding, closing, pressurizing, exhausting, maintaining pressure, opening, discharging and the like, realizing intelligent production.

[0060] Embodiment 2:

[0061] This embodiment introduces a hot pressing processing system based on the embodiment 1, wherein the feed port of the corner plate hot press machine is provided with a feed mechanism, and the discharge port of the corner plate hot press machine is provided with a discharge mechanism.

[0062] Based on this, the feeding mechanism and the discharging mechanism further improve the degree of automation of processing, reduce the intensity of manual work, and also help to improve production efficiency. In conjunction with the conveying mechanism 7 set on the corner plate hot press, the automation of feeding, pressing and discharging is realized, which greatly reduces the labor intensity of manual work.

[0063] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
