Description

Technical Field

[0001] The present application relates to the field of wood processing technical equipment, and in particular to a continuous operation square machine. Background Art

[0002] ‌Squaring machine‌ is a woodworking machine used to glue wood together into larger boards. This machine plays an important role in the processing of furniture, handicrafts, cabinets, solid wood doors, and boards. The square machine applies glue to multiple small wooden boards and then flattens and compacts them physically. After a certain period of stable drying, the boarding process is completed. It is a commonly used equipment in the production of solid wood products.

[0003] When the square machine is working, it needs to cut the wood into boards of the required size and apply glue. The hoisting equipment cooperates with manual work to neatly stack the processed boards into the square machine. The square machine starts to physically squeeze the boards to ensure that the boards are tightly fitted and maintained for a period of time until the glue solidifies to obtain the finished wooden beams. The boards need to be loaded one by one by hoisting. The whole loading process is time-consuming. In order to prevent the water on the surface of the boards loaded in the early stage from solidifying before being squeezed, glue with a longer curing time is usually selected to ensure that each part of the board can be fully squeezed before solidification and bonding to ensure structural strength.

[0004] With regard to the above-mentioned related technologies, wooden boards are loaded one by one manually in combination with machinery, which is time-consuming. In order to cope with the long loading process, glue with a long curing time needs to be selected, which further affects the efficiency of the wooden beam splicing. Summary of the invention

[0005] In order to improve the efficiency of squaring wooden beams, the present application provides a continuous operation squaring machine.

[0006] The present application provides a continuous operation square machine, which adopts the following technical solution: A continuous operation square machine comprises a base, a receiving platform for receiving and squeezing wooden boards is provided at the top of the base, a feeding conveyor for conveying wooden boards is provided on the base, a main square cylinder and an auxiliary square cylinder are provided on the base, the telescopic shaft of the main square cylinder and the telescopic shaft of the auxiliary square cylinder are arranged parallel to each other and are both parallel to the upper end surface of the receiving platform, the telescopic shaft of the main square cylinder is fixedly connected to a first squeezing block for squeezing wooden beams, and the telescopic shaft of the auxiliary square cylinder is fixedly connected to a second squeezing block for squeezing the wooden beam from one end of the wooden beam away from the first squeezing block.

[0007] By adopting the above technical scheme, the loading conveyor transports the cut and glued wooden boards to one side of the receiving platform, and pushes the wooden boards from the loading conveyor to the upper end surface of the receiving platform one by one, and the adjacent wooden boards are aligned and abutted. The main splicing cylinder drives the first extrusion block, and the auxiliary splicing cylinder drives the second extrusion block to respectively abut and apply pressure on the two sides of the wooden board. As the wooden boards are continuously loaded, the wooden beam as a whole gradually moves away from the loading conveyor. The wooden boards are loaded and squeezed at the same time, which reduces the time required for the splicing work and helps to improve the efficiency of the splicing of wooden beams.

[0008] Optionally, an extrusion beam is fixedly connected to the base, and a side pressure cylinder is provided on the side of the extrusion beam close to the receiving platform. The telescopic axis of the side pressure cylinder is arranged perpendicular to the upper end surface of the receiving platform, and the telescopic axis of the side pressure cylinder is connected to a side pressure block for aligning and extruding the wooden beam from the side.

[0009] By adopting the above technical solution, one end of the wooden board abuts against the upper end surface of the receiving platform under the action of its own gravity, thereby ensuring that the wooden boards are kept in a horizontally aligned state. The first extrusion block and the second extrusion block squeeze the wooden board from both sides respectively, which may cause some wooden boards to be displaced in the vertical direction, thereby affecting the overall straightness of the wooden beam. In this application, a side pressure cylinder and a side pressure block are provided to cooperate with the receiving platform to squeeze the wooden board from the upper and lower directions, which helps to keep the wooden board aligned during the square splicing process, thereby improving the straightness of the finished wooden beam.

[0010] Optionally, the side pressure cylinder includes a first side pressure cylinder located at one end of the extrusion beam close to the main assembly cylinder and a second side pressure cylinder located at one end of the extrusion beam close to the auxiliary assembly cylinder, the side pressure block includes a first side pressure block connected to the telescopic shaft of the first side pressure cylinder and a second side pressure block connected to the telescopic shaft of the second side pressure cylinder, and a side pressure beam is connected between the first side pressure block and the second side pressure block for increasing the contact area between the side pressure block and the wooden beam.

[0011] By adopting the above technical solution, the side pressure beam can effectively increase the contact and force application area between the side pressure beam and the top of the wooden beam, and can reduce the pressure between the side pressure beam and the wooden beam under the same pressure, thereby better protecting the wooden beam and further improving the straightness of the wooden beam.

[0012] Optionally, the first side pressure block and the second side pressure block are provided with anti-slip racks for increasing the friction coefficient between the wooden beam and one end close to the receiving platform.

[0013] By adopting the above technical solution, the present application adopts the method of extruding while loading. After the extrusion starts, the auxiliary square cylinder will continue to drive the second extrusion block to apply pressure to the wooden beam. When adding new wooden boards, the main square cylinder needs to drive the first extrusion block to separate from the wooden beam. At this time, the wooden beam may be forced to move closer to the loading conveyor under the action of the second extrusion block. The provision of a protective rack can prevent the wooden beam from being displaced during the feeding process, which helps to improve the stability of the device operation.

[0014] Optionally, the base is provided with a first guide plate for flipping the wooden board, the first guide plate includes an upper end face and a vertically arranged side end face, the upper end face includes a horizontal section and an inclined section, the horizontal section is flush with the top end of the feeding conveyor, and the inclined section is inclined from one end away from the horizontal section toward a direction close to the upper end face of the receiving platform. The first guide plate slides horizontally and is connected to the base, and the base is provided with a guide cylinder for driving the first guide plate to slide.

[0015] By adopting the above technical solution, in order to maintain stability, the wide side of the wooden board is usually in contact with the feeding conveyor when the wooden board is transported on the feeding conveyor. In the process of square splicing, sometimes it is required to glue the wide sides of adjacent wooden boards together. At this time, it is necessary to manually flip the wooden board sideways, which consumes a certain amount of labor. The first guide plate can automatically flip the wooden board 90 degrees and turn it sideways during the process of moving from the conveyor to the receiving platform, which helps to further save labor and improve square splicing efficiency.

[0016] Optionally, a second guide plate is vertically slidably connected to the base, the sliding direction of the second guide plate is perpendicular to the conveying direction of the feeding conveyor, the upper end surface of the second guide plate is horizontally arranged, and a guide drive device for driving the second guide plate to slide is provided on the base.

[0017] By adopting the above technical solution, during the square process, it is sometimes required to glue the narrow sides of adjacent wooden boards together. At this time, the wooden boards need to be transferred from the feeding conveyor to the receiving platform in the state they were conveyed in. After the wooden boards are transferred to the second guide plate, they can be vertically transferred to the upper surface of the receiving platform along with the second guide plate while maintaining their original state.

[0018] Optionally, a discharging conveyor for conveying wooden beams is provided on the base, and the discharging conveyor is located at one end of the receiving platform away from the loading conveyor, and the top end of the discharging is flush with the upper end surface of the receiving platform.

[0019] By adopting the above technical solution, the weight of the finished wooden beams is further increased. It is difficult to transfer the wooden beams in time by manual labor alone. Manual labor and crane are required to transfer them, but the efficiency is low, which affects the continuous progress of the square work. A discharge conveyor is set up, and the wooden beams that have completed the square work can be directly transferred to the discharge conveyor under the drive of the first extrusion block, thereby realizing rapid discharge, which helps to further improve the efficiency of the wooden beam square work.

[0020] Optionally, the base is provided with a push plate and a push assembly for driving the push plate to slide.

[0021] By adopting the above technical solution, the pushing assembly drives the pushing plate to move, thereby stably transferring the wooden board to the receiving table.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. After pushing the wooden boards one by one from the feeding conveyor to the upper end surface of the receiving platform, the main splicing cylinder drives the first extrusion block, and the auxiliary splicing cylinder drives the second extrusion block to respectively press the two sides of the wooden board and apply pressure to start the splicing work. As the wooden boards are continuously fed, the wooden beam as a whole gradually moves away from the feeding conveyor. The splicing is done while feeding, which reduces the time required for the splicing work. Water with a shorter curing time can be selected, which helps to improve the efficiency of splicing the wooden beams. 2. After the extrusion and splicing process begins, the auxiliary splicing cylinder will continue to drive the second extrusion block to apply pressure to the wooden beam. When a new wooden board is added, the main splicing cylinder drives the first extrusion block to separate from the wooden beam. At this time, the wooden beam may be moved toward the feeding conveyor under the action of the second extrusion block. The present application provides a protective rack to prevent the wooden beam from being displaced during the feeding process, which helps to improve the stability of the device operation.

[0032] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0033] The embodiment of the present application discloses a continuous operation square assembling machine.

[0034] Reference Figure 1 and Figure 2 A continuous operation square machine includes a base 1 for installing equipment used for square assembly and providing support. The base 1 is equipped with a feeding conveyor 3, which adopts a roller conveyor. After the cut wood boards are coated with glue, they are transported to the working position through the feeding conveyor 3. The top of the base 1 is fixedly connected with a receiving platform 2, which is made of metal material, and its upper end surface is flat and smooth and in a horizontal state. When square assembly, the wood boards will be transferred to the receiving platform 2, and the receiving platform 2 is used to provide support and align adjacent wood boards. A main splicing cylinder 4 and an auxiliary splicing cylinder 5 are installed on the base 1, and the two are respectively located on both sides of the receiving platform 2. The loading conveyor 3 transports the cut and glued wooden boards to one side of the receiving platform 2, and pushes the wooden boards one by one from the loading conveyor 3 to the upper end surface of the receiving platform 2, and the splicing work is carried out by the main splicing cylinder 4 and the auxiliary splicing cylinder 5. With the continuous loading of wooden boards, the wooden beam as a whole gradually moves to the side away from the loading conveyor 3, and squeezes while adding materials, which reduces the time required for the splicing work and helps to improve the efficiency of the wooden beam splicing.

[0035] Reference Figure 1 and Figure 2, the main square oil cylinder 4 and the auxiliary square oil cylinder 5 are arranged in several groups and are neatly distributed on both sides of the receiving platform 2. The main square oil cylinder 4 is located on the side of the receiving platform 2 close to the feeding conveyor 3, and the auxiliary square oil cylinder 5 is located on the side of the receiving platform 2 away from the feeding conveyor 3. The telescopic axes of the main square oil cylinder 4 and the auxiliary square oil cylinder 5 are arranged parallel to each other and are parallel to the upper end surface of the receiving platform 2. The telescopic axis of the main square oil cylinder 4 is fixedly connected to the first extrusion block 41, and the telescopic axis of the auxiliary square oil cylinder 5 is fixedly connected to the second extrusion block 51. During the square operation, the main square oil cylinder 4 drives the first extrusion block 41, and the auxiliary square oil cylinder 5 drives the second extrusion block 51 to respectively press and apply pressure on the two sides of the wooden board, and realize the uniform movement of the wooden board in the discharge direction through the pressure difference on both sides.

[0036] Reference Figure 2 and Figure 3 When the wooden board is on the receiving platform 2, it only relies on its own gravity to abut against the upper end surface of the receiving platform 2, thereby ensuring that the wooden boards remain in a horizontally aligned state. When the first extrusion block 41 and the second extrusion block 51 squeeze the wooden boards from both sides respectively, some of the wooden boards may be displaced in the vertical direction, thereby affecting the overall straightness of the wooden beam. In this embodiment, an extrusion beam 6 is fixedly connected to the base 1, and the horizontal part of the extrusion beam 6 is arranged above the receiving platform 2. A lateral pressure cylinder 61 is installed on the side of the extrusion beam 6 close to the receiving platform 2. The telescopic axis of the lateral pressure cylinder 61 is arranged perpendicular to the upper end surface of the receiving platform 2, and a lateral pressure block 62 is installed at its end. When squaring, the lateral pressure cylinder 61 cooperates with the receiving platform 2 to squeeze the wooden boards from the upper and lower directions, which helps to maintain the alignment of the wooden boards during the squaring process, thereby improving the straightness of the finished wooden beams.

[0037] Reference Figure 2 and Figure 3 The side pressure cylinder 61 includes a first side pressure cylinder 611 and a second side pressure cylinder 612. The first side pressure cylinder 611 is located at one end of the extrusion beam 6 close to the main square cylinder 4, and the second side pressure cylinder 612 is located at one end of the extrusion beam 6 close to the auxiliary square cylinder 5. The side pressure block 62 includes a first side pressure block 621 and a second side pressure block 622. The first side pressure block 621 is connected to the telescopic shaft of the first side pressure cylinder 611, and the second side pressure block 622 is connected to the telescopic shaft of the second side pressure cylinder 612. A side pressure beam 63 is connected between the first side pressure block 621 and the second side pressure block 622, which can effectively increase the contact area with the top of the wooden beam. Under the same pressure, the pressure between the wooden beam and the wooden beam can be effectively reduced, the degree of intrusion and damage to the wooden beam can be weakened, the wooden beam can be effectively protected, and the straightness of the wooden beam can be further improved.

[0038] Reference Figure 2 , Figure 3 and Figure 4, the present application adopts the method of squeezing while feeding. After the squaring operation begins, it is necessary to continuously apply pressure to the wooden beam, so the auxiliary squaring cylinder 5 will continuously drive the second squeezing block 51 to apply pressure to the wooden beam. When adding new wooden boards, the main squaring cylinder 4 needs to drive the first squeezing block 41 to separate from the wooden beam. The wooden beam loses pressure on one side and may move toward the feeding conveyor 3 under the action of the second squeezing block 51, affecting the continued feeding. In this embodiment, the first side pressure block 621 and the second side pressure block 622 are installed with an anti-slip rack 623 near one end of the receiving platform 2, which can increase the friction coefficient between the wooden beam and prevent the wooden beam from being displaced during the feeding process, which helps to improve the stability of the device operation.

[0039] Reference Figure 1 and Figure 5 In order to keep the wooden board in a stable state during the conveying process and prevent it from tipping over, the wooden board is usually kept in a state where the wide side is in contact with the feeding conveyor 3 when being transported on the feeding conveyor 3. In the process of square splicing, it is sometimes required to glue the wide sides of adjacent wooden boards to each other, that is, the wooden board needs to be flipped on the receiving platform 2 so that the narrow side is in contact with the receiving platform 2. If the wooden board is flipped sideways manually, the labor cost is high. In the present application, a first guide plate 11 is installed on the base 1. The first guide plate 11 includes an upper end face and a vertically arranged side end face. The upper end face includes a horizontal section 111 and an inclined section 112. The horizontal section 111 is flush with the top of the feeding conveyor 3. The inclined section 112 is inclined from one end away from the horizontal section 111 to the direction close to the upper end face of the receiving platform 2. The first guide plate 11 is horizontally slidably connected to the base 1. A guide cylinder 14 is installed on the base 1. The telescopic shaft of the guide cylinder 14 is fixedly connected to the first guide plate 11 to drive the first guide plate 11 to slide. When the wooden board moves from the feeding conveyor 3 to the receiving platform 2, it can automatically flip along with the change of the inclination angle of the upper end surface of the first guide plate 11, and finally become a sideways state, which helps to further save labor and improve the efficiency of square assembly.

[0040] Reference Figure 1 and Figure 6 During the square splicing process, it is sometimes required to glue the narrow sides of adjacent wooden boards together. At this time, the wooden boards need to maintain the state during transportation and be directly transferred from the feeding conveyor 3 to the receiving platform 2. In the embodiment of the present application, a second guide plate 12 is vertically slidably connected to the base 1. The sliding direction of the second guide plate 12 is perpendicular to the conveying direction of the feeding conveyor 3. The upper end surface of the second guide plate 12 is horizontally arranged. A guide drive device 15 is provided on the base 1 for driving the second guide plate 12 to slide. After the wooden board is transferred to the upper end surface of the second guide plate 12, it can maintain its original state and be vertically transferred to the upper surface of the receiving platform 2 with the second guide plate 12, thereby realizing a flexible transition between the two wooden board splicing methods.

[0041] Reference Figure 5 and Figure 6 The guide drive device 15 includes a servo motor 151, a transmission assembly 152 and a transmission chain 153. The second guide plate 12 is fixedly connected to the transmission chain 153. The transmission chain 153 can drive the second guide plate 12. The transmission assembly 152 is used to connect the servo motor 151 and the transmission chain 153, so that the servo motor 151 can drive the transmission chain 153 to move, thereby driving the second guide plate 12 to slide.

[0042] Reference Figure 1 and Figure 2 The wooden beam that has been squared off is a combination of multiple wooden boards glued together, and its weight is further increased. It is difficult to transfer the wooden beams in time by manual labor alone. Usually, manual labor and crane transfer are required, but the efficiency is low, and the corresponding position of the receiving platform 2 will be occupied for a long time, affecting the continuous squared off work. A discharge conveyor 7 is installed on the base 1, which is located at the end of the receiving platform 2 away from the loading conveyor 3. The top of the discharge conveyor 7 is flush with the upper end surface of the receiving platform 2. The wooden beams that have completed the squared off work can be directly transferred to the discharge conveyor 7 under the drive of the first extrusion block 41. The wooden beams are directly transferred by the discharge conveyor 7, which can achieve rapid discharge and help to further improve the efficiency of the squared off work of the wooden beams.

[0043] Reference Figure 7 and Figure 8 The wooden boards are usually of large mass. Manually transferring the wooden boards from the loading conveyor 3 to the receiving platform 2 is inefficient and costly. In the present application, a pushing assembly 13 is provided on the base 1. The pushing assembly 13 includes a pushing arm 132. The pushing arm 132 is provided with a pushing plate 131 for pushing the wooden board to move. The pushing arm 132 is horizontally slidably connected to the base 1. A pushing motor 133 is provided on the base 1. The output shaft of the pushing motor 133 is coaxially fixedly connected with a pushing gear 134. A pushing rack 135 meshing with the pushing gear 134 is fixedly connected to the pushing arm 132. The pushing motor 133 drives the pushing gear 134 to rotate, and the pushing gear 134 drives the pushing rack 135 to move, thereby driving the pushing arm 132 and the pushing plate 131 to move, so as to stably transfer the wooden board to the receiving platform 2 and save labor.

[0044] The implementation principle of a continuous operation square splicing machine in an embodiment of the present application is as follows: the wood raw materials are cut into wooden boards of required sizes, and glue is applied to the wooden boards. The loading conveyor 3 conveys the wooden boards to one side of the receiving platform 2. The pushing assembly 13 drives the pushing plate 131 to move and stably transfer the wooden boards to the receiving platform 2. Adjacent wooden boards are aligned and abutted. The side pressure cylinder 61 cooperates with the receiving platform 2 to squeeze the wooden boards from the upper and lower directions to keep the wooden boards aligned during the square splicing process. The main square splicing cylinder 4 drives the first squeezing block 41, and the auxiliary square splicing cylinder 5 drives the second squeezing block 51 to respectively abut and apply pressure on the two sides of the wooden board to start the square splicing work. As the wooden boards are continuously fed, the wooden beam as a whole gradually moves to the side away from the loading conveyor 3, and is squeezed while feeding, which reduces the time required for the square splicing work, and then watering with a shorter curing time can be selected, which helps to improve the efficiency of the wooden beam square splicing.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
