Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of cold presses, specifically to a multi-layer wooden building template cold press. Background Technology

[0002] In the production of multi-layer wooden building formwork, the cold press is the core equipment for bonding the boards. It applies pressure to the baseboard and the face layer to ensure that the glue is fully cured and forms a stable composite structure. However, existing cold presses have significant drawbacks in practical applications, especially the cleaning problem during the pressing process, which seriously affects the production quality and efficiency of the formwork.

[0003] Traditional cold presses inevitably encounter interference from impurities and wood chips before and after pressing the boards. On one hand, factory environments commonly contain dust, fibers, and other impurities that easily settle on the pressing base surface of the cold press. On the other hand, during transportation and pre-treatment, vibrations may cause surface wood chips to fall off and accumulate in the pressing area. If these impurities and wood chips are not removed promptly, they will be squeezed to the bottom surface of the board during subsequent pressing, forming protrusions or granular defects. For example, when the base layer board is pressed with the face layer, wood chips from the base can become embedded in the glue layer, causing unevenness on the board surface. In severe cases, this can lead to poor adhesion, delamination, and other quality problems, affecting the flatness and structural strength of multi-layer templates.

[0004] Long-term uncleaned pressing bases can become a source of contamination, leading to continuous quality problems in subsequent batches of formwork, increasing scrap rates and rework costs. For high-precision building formwork, surface flatness is a critical indicator. Defects caused by impurities can lead to problems such as grout leakage and surface roughness during concrete pouring, affecting the forming quality of building components. Furthermore, manually cleaning the pressing bases requires machine downtime, which is not only time-consuming and labor-intensive but also disrupts the production line, reducing efficiency. This is especially true in large-scale industrial production, where the time and economic losses from frequent cleaning are even more significant.

[0005] With the increasing demands for formwork quality in the construction industry and the growing popularity of green production and efficient manufacturing concepts, the shortcomings of traditional cold presses in terms of cleanliness have become a bottleneck restricting industrial upgrading. Developing a cold press that can automatically remove impurities from the pressing base and maintain a clean pressing environment is urgently needed. Utility Model Content

[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide a multi-layer wooden building formwork cold press, which solves the technical problem in the prior art where sawdust on the base gets embedded in the glue layer, causing unevenness on the surface of the board, and in severe cases, may cause poor bonding, delamination and other quality problems, affecting the flatness and structural strength of the multi-layer formwork.

[0007] According to one aspect, at least one embodiment of this disclosure provides a multi-layer wooden building formwork cold press, comprising:

[0008] A base and a top frame, wherein the top frame is mounted on the base;

[0009] A pair of hydraulic cylinders and a cold pressing plate, wherein the hydraulic cylinders are both located at the bottom of the top frame, and the cold pressing plate is located at the output end of the hydraulic cylinders;

[0010] A material ejection assembly is disposed in the base;

[0011] An outer frame and a cleaning component are provided, wherein the outer frame is disposed on the base and the cleaning component is disposed on both the outer frame and the base;

[0012] The cleaning assembly includes a pair of telescopic cylinders, both of which are located at the bottom ends of the base. The output end of the telescopic cylinder is connected to the bottom of the outer frame. The outer frame slides against the side surface of the base for a circumference. A groove is formed on the surface of the base, which is located directly below the outer frame. A collection groove is formed on the inner surface of the outer frame.

[0013] As a further technical solution, a pusher auger is installed in the collection tank, a pair of long slots are opened on the top of the outer frame, and a drive screw and a guide rod are respectively installed in the long slots. A flat slot is opened at one end of the top of the outer frame.

[0014] As a further technical solution, a movable pipe is connected to the drive screw and the guide rod. The movable pipe is located in the flat groove, and an air pipe is provided on one side of the movable pipe. Several air blowing holes are opened on the side surface of the movable pipe.

[0015] As a further technical solution, the unloading assembly includes a pair of ports, both of which are opened at both ends of the base surface. A pair of second cylinders are provided at both ends of the bottom of the base, and the output end of the second cylinders is connected to an inner frame.

[0016] As a further technical solution, a pair of drive shafts are rotatably connected in the inner frame, and conveyor wheels are provided at both ends of the drive shafts. A pair of drive motors are provided at the bottom of the inner frame, and transmission gears are provided at the output end of the drive motors and on the drive shafts.

[0017] As a further technical solution, the outer frame and the upper surface of the moving pipe are located on the same horizontal plane, and after the outer frame is lowered to its lowest point, the upper surface is flush with the base surface.

[0018] As a further technical solution, the surface of the conveyor wheel is an anti-slip structural surface.

[0019] As a further technical solution, one end of the collection tank is an open structure, and the pushing auger extends to the outside.

[0020] The beneficial effects of the embodiments disclosed herein are as follows:

[0021] 1. The beneficial effects of the cleaning component in this disclosure are that the telescopic cylinder drives the outer frame to slide up and down, and in conjunction with the lateral movement of the moving pipe, it achieves all-round cleaning of the base surface. The airflow from the blowing holes can effectively blow away impurities and sawdust, preventing them from remaining on the base surface. The design of the collection trough and the pushing auger ensures that the residue is discharged in time, preventing secondary pollution. This automatic cleaning method requires no manual intervention and can complete the cleaning simultaneously during the unloading process, avoiding the time-consuming and downtime problems of traditional manual cleaning. It significantly improves the cleanliness of the pressing environment, thereby ensuring the flatness and bonding quality of subsequent board pressing, reducing the scrap rate caused by impurities, and improving production efficiency and product quality stability.

[0022] 2. In this disclosure, the beneficial effects of the unloading assembly are as follows: the design of the second cylinder and the inner frame enables automatic ejection of the formed sheet material; the anti-slip surface of the conveyor wheels ensures stable conveying of the sheet material; and the drive motor synchronously controls the rotation of the transmission shaft through the transmission gears, making the sheet material unloading process uniform and stable, avoiding damage to the sheet material that may be caused by manual handling. The temporary conveying platform formed after the outer frame descends to be level with the base, in conjunction with the conveyor wheels, enables continuous output of the sheet material, improving the automation level of the production line.

[0035] like Figures 1-4 As shown, it illustrates a multi-layer wooden building formwork cold press according to an embodiment of the present disclosure, comprising:

[0036] A base 1 and a top frame 2, wherein the top frame 2 is disposed on the base 1;

[0037] A pair of hydraulic cylinders 3 and a cold pressing plate 4 are provided. The hydraulic cylinders 3 are all located at the bottom of the top frame 2, and the cold pressing plate 4 is located at the output end of the hydraulic cylinders 3.

[0038] Material ejection assembly 7 is disposed in the base 1;

[0039] The outer frame 5 and the cleaning component 6 are provided, wherein the outer frame 5 is disposed on the base 1 and the cleaning component 6 is disposed on the outer frame 5 and the base 1.

[0040] The cleaning component 6 includes a pair of telescopic cylinders 6-1, both of which are located at the bottom ends of the base 1. The output end of each telescopic cylinder 6-1 is connected to the bottom of the outer frame 5. The outer frame 5 slides against the side surface of the base 1 for a circumference. A groove 6-2 is formed on the surface of the base 1, located directly below the outer frame 5. A collection groove 6-3 is formed on the inner surface of the outer frame 5, and a pusher auger 6-4 is installed in the collection groove 6-3. A pair of long grooves 6-5 are formed on the top of the outer frame 5, and a drive screw 6-6 and a guide rod 6-7 are respectively arranged in the long grooves 6-5. A flat groove 6-8 is formed at one end of the top of the outer frame 5. A moving pipe 6-9 is connected to the drive screw 6-6 and the guide rod 6-7. The moving pipe 6-9 is located in the flat groove 6-8. An air pipe 6-10 is provided on one side of the moving pipe 6-9, and several air holes 6-11 are formed on the side surface of the moving pipe 6-9.

[0041] In some examples, during the continuous operation of a multi-layer wooden formwork cold press, a cleaning component 6 is designed to keep the surface of the base 1 clean. This component is powered by a pair of telescopic cylinders 6-1 located at both ends of the bottom of the base 1. The output end of the telescopic cylinders 6-1 is connected to the bottom of the outer frame 5, which can drive the outer frame 5 to slide up and down along the side surface of the base 1. The grooves 6-2 on the surface of the base 1 are located directly below the outer frame 5. A pusher auger 6-4 installed in the collection groove 6-3 on the inner surface of the outer frame 5 can transport the cleaned residue outward. The grooves 6-2 are concentrated directly below the pusher auger 6-4 because... Equipped with a pusher auger 6-4, the bottom of which protrudes slightly, it can enter the groove 6-2 when descending. It is located in a pair of long slots 6-5 on the top of the outer frame 5. The moving pipe 6-9, which is connected to the drive screw 6-6 and the guide rod 6-7, can move along the long slots 6-5 when the drive screw 6-6 rotates. The air pipe 6-10 connected to one side of the moving pipe 6-9 blows air through the air hole 6-11, which can blow off the residue on the surface of the base 1, causing it to fall into the groove 6-2 and enter the collection tank 6-3. The pusher auger 6-4 transports the residue from the collection tank 6-3 to the flat slot 6-8 on the top of the outer frame 5, and finally discharges it outside the equipment.

[0042] Through the coordinated operation of components such as telescopic cylinder 6-1, outer frame 5, groove 6-2, collection groove 6-3, push auger 6-4, drive screw 6-6, guide rod 6-7, moving pipe 6-9, air pipe 6-10 and blowing hole 6-11, the cleaning component 6 realizes the function of cleaning the residue on the surface of the base 1 by blowing air and discharging it outward.

[0043] like Figures 1-4 As shown in the figure, the material unloading assembly 7 in this embodiment includes a pair of ports 7-1, both of which are opened at both ends of the surface of the base 1. A pair of second cylinders 7-2 are provided at both ends of the bottom of the base 1. The output end of the second cylinders 7-2 is connected to an inner frame 7-3. A pair of drive shafts 7-4 are laterally rotatably connected in the inner frame 7-3. Both ends of the drive shafts 7-4 are provided with conveying wheels 7-5. A pair of drive motors 7-6 are provided at the bottom of the inner frame 7-3. The output end of the drive motors 7-6 and the drive shafts 7-4 are provided with transmission gears 7-7. The outer frame 5 and the upper surface of the moving pipe 6-9 are located on the same horizontal plane. After the outer frame 5 is lowered to its lowest point, its upper surface is flush with the surface of the base 1.

[0044] In some examples, after the multi-layer wooden building template is cold-pressed, a material ejection assembly 7 is designed to facilitate the removal of the boards. This assembly has a pair of openings 7-1 at both ends of the surface of the base 1. The output ends of the second cylinders 7-2 set at both ends of the bottom of the base 1 are connected to the inner frame 7-3. The transmission shaft 7-4 connected laterally in the inner frame 7-3 is equipped with conveyor wheels 7-5 at both ends for supporting and conveying the formed boards. The drive motor 7-6 at the bottom of the inner frame 7-3 drives the transmission shaft 7-4 to rotate through the transmission gear 7-7, causing the conveyor wheels 7-5 to rotate and push the boards. When the cold-pressed plate 4 rises and resets, the second cylinder 7-2 drives the inner frame 7-3 to rise, and the conveyor wheels 7-5 extend from the openings 7-1 out of the surface of the base 1 to push the boards outward. When the outer frame 5 descends to its lowest point, its upper surface is flush with the surface of the base 1, which can serve as a temporary conveying platform to smoothly deliver the boards in conjunction with the conveyor wheels 7-5.

[0045] Through the coordinated operation of components such as the through-hole 7-1, the second cylinder 7-2, the inner frame 7-3, the drive shaft 7-4, the conveying wheel 7-5, the drive motor 7-6, and the transmission gear 7-7, the unloading assembly 7 realizes the function of pushing the formed sheet material outward for easy removal.

[0046] For example, such as Figure 1 As shown, the surface of the conveyor wheel 7-5 is an anti-slip structure.

[0047] In some examples, the anti-slip surface allows the plate to be moved outwards stably during rotation after contact with the plate surface.

[0048] For example, such as Figure 3 As shown, one end of the collection groove 6-3 is an open structure, and the pusher auger 6-4 extends to the outside.

[0049] In some examples, the open structure allows the collected residue to be discharged outwards via the pusher auger 6-4, facilitating collection.

[0050] In actual use: First, place the base plate and the panel layer on the surface of the base 1 in sequence. Start the hydraulic cylinder 3 to drive the cold pressing plate 4 to descend and apply pressure to the plate to complete the bonding. After the pressing is completed, the hydraulic cylinder 3 resets. The second cylinder 7-2 of the unloading component 7 drives the inner frame 7-3 to rise. The conveying wheel 7-5 extends out from the opening 7-1. The drive motor 7-6 drives the conveying wheel 7-5 to rotate through the transmission gear 7-7, conveying the formed plate outward. At the same time, the telescopic cylinder 6-1 of the cleaning component 6 drives the outer frame 5 to rise. The moving pipe 6-9 moves along the long groove 6-5 under the action of the drive screw 6-6 and the guide rod 6-7. The air pipe 6-10 sprays air through the air blowing hole 6-11 to blow impurities and wood chips on the surface of the base 1 into the collection groove 6-3 inside the outer frame 5. The auger 6-4 pushes the residue in the collection groove 6-3 out of the equipment through the opening structure to ensure that the surface of the base 1 is clean and ready for the next pressing operation.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
