Description

Technical Field

[0001] This utility model relates to the field of flooring processing and production technology, and in particular to an automated production line for four-sided tongue and groove forming of flooring. Background Technology

[0002] Solid wood flooring and engineered wood flooring with a solid wood layer are popular flooring materials for home decoration. They attract consumers with their unique and natural wood texture, fresh and natural wood color, nostalgic light brown, simple and luxurious light gray, and other colorful options, as well as their comfortable and gentle feel underfoot.

[0003] The flooring production process requires a four-sided planing tongue-and-groove forming step. Currently, this step is completed in two sections. First, the double-end tongue-and-groove forming requires three people: one to hold the board, one to place it on the machine slot, and one to collect and stack the board. This requires high skill and physical strength from the workers. Next, the four-sided planing is used to cut the tongue and groove on the two long sides, requiring two people per machine: one to feed the board and one to collect and stack it. A total of seven people are needed to complete the process, including one double-end milling machine and two four-sided planers, with an average daily output of approximately 214 square meters per person. However, the aging of the frontline staff is becoming increasingly apparent, and the high physical demands and dependency on these workers are significant issues.

[0004] In the four-sided planer section, a dedicated person is required to feed the planks. This is because the planks coming from the production line inevitably shift, and shifted planks cannot enter the four-sided planer, or if they do, they will negatively impact the efficiency and accuracy of milling and planing. Therefore, a dedicated person needs to stand in front of the four-sided planer's feed inlet to ensure the planks are firmly against the machine before they enter the equipment via the production line. This is labor-intensive and poses safety hazards during operation. Moreover, conventional production lines cannot meet the rhythm requirements of a section using one double-end milling machine and two four-sided planers.

[0005] In view of this, how to solve the problems of high dependence on personnel, high labor intensity, and inability to meet the rhythm requirements of the production process in the existing four-sided tongue and groove forming process of flooring has become the research topic to be solved by this utility model. Summary of the Invention

[0006] The purpose of this invention is to provide an automated production line for four-sided tongue-and-groove molding of flooring.

[0007] To achieve the above objectives, this utility model proposes an automated production line for four-sided tongue-and-groove forming of flooring products. The automated production line includes a double-end milling machine and a four-sided planer. Its innovation lies in:

[0008] The double-end milling machine is located at the front end of the automated production line, and the four-sided planer is located at the rear end of the automated production line.

[0009] An automatic lifting frequency station is led out from the discharge end of the double-end milling equipment.

[0010] The discharge end of the automatic lifting frequency stage is equipped with a double-layer frequency stage.

[0011] At least two flow frequency separation lines are provided at the discharge end of the double-layer flow frequency station, and the end of the flow frequency separation line is provided with a pressure roller for pressing down the floor.

[0012] Each of the aforementioned flow frequency separation lines is equipped with a material storage flow frequency station at its discharge end. The material storage flow frequency station includes a front-end material storage station located at the front end for material storage and a rear-end conveying and adjustment station located at the rear end for floor product conveying and adjustment.

[0013] The material storage flow frequency station is equipped with a feeding platform at the end of the conveying and adjusting station. The feeding platform has a feeding backrest set along the length of the feeding platform. The feeding platform is also equipped with an auxiliary pusher device for automatically pushing the flooring products toward the feeding backrest and pressing them together.

[0014] The four-sided planer is installed at the discharge end of the feeding platform.

[0015] The relevant contents of this utility model are explained as follows:

[0016] 1. This utility model addresses the problems of high reliance on personnel, high labor intensity, and inability to meet the pace requirements of existing four-sided tongue-and-groove forming processes for flooring. An innovative automated production line for four-sided tongue-and-groove forming of flooring is designed. This automated production line is arranged sequentially from the production line direction, consisting of a double-end milling machine, an automatic lifting flow frequency table, a double-layer flow frequency table, and a flow frequency separation line. Multiple branches branch off from the discharge end of the flow frequency separation line, with a material storage flow frequency table, a feeding platform, and a four-sided planer arranged sequentially from the production line direction on each branch. This design achieves automated production line integration of a double-end milling machine (one double-end milling machine) and two or more four-sided planer stations, requiring only 5 people to complete the process. The average daily output per person is approximately 300 square meters, significantly improving production efficiency and effectively reducing costs. Furthermore, in this automated production line… To address the issue of flooring products deviating during transfer from the flow meter, specific equipment improvements have been implemented at each major flow meter as anti-deviation measures. Specifically, a first pressure roller is installed at the end of the flow meter separation line to hold the flooring in place. A conveying adjustment station for flooring products is located at the rear end of the storage flow meter. A feeding support is installed along the length of the feeding platform, along with an auxiliary pusher device to automatically push the flooring products towards the feeding support for pressing. This automated assembly line structure and automated equipment correct the flooring products, ensuring they smoothly enter the four-sided planer. This eliminates the need for dedicated personnel to feed the boards and ensures more stable, faster, and more precise conveying of the flooring products, improving the processing efficiency and quality of the four-sided tongue-and-groove forming process.

[0017] 2. In this utility model, a sensor device is provided on the automatic lifting flow table near the discharge end. When the number of products passing through is detected by the sensor and reaches the set amount, the lifting cylinder is activated, automatically lowering or raising the product, and the product is systematically and orderly distributed to the two four-sided planer tongue and groove forming machines, and the operation is repeated in this cycle.

[0018] 3. In this utility model, the dual-layer flow table includes an upper flow table and a lower flow table. Corresponding to the automatic lifting flow table, the heights of the upper and lower flow tables are both lower than the height of the automatic lifting flow table when it is in a high position. This allows the automatic lifting flow table to automatically transfer the flooring products to the upper and lower flow tables. The upper flow table products are transferred to the #1 four-sided planer, and the lower flow table products are transferred to the #2 four-sided planer.

[0019] 4. In this utility model, the upper and lower layers of the dual-layer flow frequency station are each provided with a first support and a first baffle. The distance between the first support and the first baffle is 8mm to 15mm larger than the width of the floor product, so that the board can automatically flow from both ends to the four-sided planer and form a straight line. The height of the first support and the first baffle above their respective upper and lower flow frequencies is 5mm to 10mm, and the height of the first support and the first baffle is less than the thickness of the floor product, so as to prevent the product from flying off the flow frequency line when abnormalities such as jamming occur.

[0020] 5. In this utility model, the flow frequency separation line is provided with a first pressure roller with a bearing near the discharge end. The distance between the bottom of the first pressure roller and the flow frequency separation line is 10mm~12mm. The first pressure roller presses down on the floor product and pushes the board onto the storage flow frequency platform through the flow frequency speed, so as to avoid the floor product from deviating or rushing out of the front end at high speed.

[0021] 6. In this invention, an adjustable baffle block is provided at the front storage station of the material storage and flow table. The height of the baffle block relative to the flow table is 5mm to 10mm higher than the thickness of a flooring product, and the baffle block is inclined at a 45° angle to the material storage and flow table. The height between the baffle and the flow table is adjusted appropriately according to the thickness of the product being produced, so that the products can enter the next process in an orderly manner. The baffle block is composed of metal and plastic blocks to prevent damage to the ends of the flooring products.

[0022] 7. In this utility model, a second pressure roller and a third pressure roller are sequentially arranged on the conveying adjustment station of the material flow frequency table. The distance between the second pressure roller and the material flow frequency table is 5mm~10mm, and the distance between the third pressure roller and the material flow frequency table is 10mm~12mm. The second pressure roller and the third pressure roller press down on the floor product in turn and push the board onto the feeding platform through the flow frequency speed to avoid the floor product from deviating.

[0023] 8. In this invention, the conveying adjustment station has a second support and a second baffle, which form a flared opening at a 15° angle to allow for smoother discharge of the flooring products.

[0024] 9. In this utility model, the auxiliary push plate device includes a push plate driving unit and a push plate arm. The push plate arm is equipped with a plurality of auxiliary pressure rollers acting on the upper surface of the flooring product and a plurality of auxiliary top rollers acting on the side of the flooring product. The push plate driving unit periodically drives the push plate arm to move toward the feeding backrest to further prevent the flooring product from deviating.

[0025] 10. In this utility model, the length extension direction of the push plate arm is parallel to the feeding backrest. Five auxiliary top rollers are spaced apart on the push plate arm. The auxiliary top rollers are spring rubber rollers, and the spacing between the auxiliary top rollers is 190mm~200mm. Four auxiliary pressure rollers are spaced apart on the push plate arm. The auxiliary pressure rollers are rubber pressure rollers, and each auxiliary pressure roller is correspondingly positioned between two auxiliary top rollers. This design ensures that before entering the four-sided planer, the flooring product is forced to fit tightly against the feeding backrest by the combined action of the auxiliary top rollers and auxiliary pressure rollers on the feeding platform. The positions of the auxiliary top rollers and auxiliary pressure rollers are reasonably designed, resulting in a greater effect.

[0026] 11. In this utility model, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0027] 12. In this utility model, the terms “center”, “upper”, “lower”, “axial”, “bottom”, “inner”, “outer”, etc., indicate the orientation or positional relationship based on the orientation or positional assembly relationship shown in the drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0028] 13. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] Due to the application of the above solution, this utility model has the following advantages and effects compared with the prior art:

[0030] 1. The above-mentioned solution of this utility model addresses the problems of high dependence on personnel, high labor intensity, and inability to meet the rhythm requirements of the existing four-sided tongue and groove forming process of flooring. It innovatively designs an automatic production line for four-sided tongue and groove forming of flooring. The automatic production line for four-sided tongue and groove forming of flooring is arranged in sequence from the production line direction as a double-end milling machine, an automatic lifting flow frequency table, a double-layer flow frequency table, and a flow frequency separation line table. Then, multiple branches are set from the discharge end of the flow frequency separation line table. On the branches, a material storage flow frequency table, a feeding platform, and a four-sided planer are arranged in sequence from the production line direction. This design realizes the automation of the production line by combining the double-end milling of one double-end milling machine with the four-sided planing station of two or more four-sided planers. Only 5 people are needed to complete the work, and the daily output per person is about 300 square meters, which can greatly improve production efficiency and effectively improve efficiency and reduce costs.

[0031] 2. In the above-described solution of this utility model, and in the automated production line, to address the problem of flooring products deviating during the transfer process from the flow frequency, corresponding equipment improvements have been made in each major flow frequency as anti-deviation measures. Specifically, a first pressure roller for pressing down the flooring is provided at the end of the flow frequency separation line, a conveying adjustment station for adjusting the flooring product is set at the rear end of the storage flow frequency station, and a feeding support is set along the length of the feeding platform on the feeding platform. An auxiliary pusher device is also provided to automatically push the flooring product towards the feeding support for pressing. This allows the automated production line structure and automated devices to correct the flooring product, ensuring it smoothly enters the four-sided planer. This eliminates the need for dedicated personnel to feed the boards and ensures more stable, faster, and more precise conveying of the flooring product, improving the processing efficiency and quality of the four-sided tongue-and-groove forming process.

[0066] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0067] This utility model aims to solve the problems of high dependence on personnel, high labor intensity, and inability to meet the rhythm requirements of the production process in the existing four-sided tongue and groove forming process of flooring. It innovatively designs an automatic production line for four-sided tongue and groove forming of flooring, realizing an automatic production line from automatic double end to forming tongue and groove. After automatic assembly, it can greatly improve production efficiency and effectively improve efficiency and reduce costs.

[0068] like Figures 1 to 7 As shown, this utility model proposes an automatic production line for four-sided tongue and groove forming of flooring products. The automatic production line includes a double-end milling machine 8 and a four-sided planer 9. The double-end milling machine 8 is located at the front end of the automatic production line, and the four-sided planer 9 is located at the rear end of the automatic production line.

[0069] An automatic lifting frequency stage 1 is led out from the discharge end of the double-end milling machine 8.

[0070] The discharge end of the automatic lifting frequency stage 1 is equipped with a double-layer frequency stage 2.

[0071] At least two flow frequency separation line stations 3 are provided at the discharge end of the double-layer flow frequency station 2, and the end of the flow frequency separation line station 3 is provided with a pressure roller for pressing down the floor.

[0072] Each of the flow frequency separation line stations 3 is provided with a material storage flow frequency station 4 at the discharge end. The material storage flow frequency station 4 includes a front material storage station 41 located at the front for material storage and a conveying adjustment station 42 located at the rear for conveying and adjusting floor products.

[0073] The material storage flow frequency station 4 has a feeding platform 5 at the end of the conveying adjustment station 42. The feeding platform 5 has a feeding backrest arranged along the length of the feeding platform 5. The feeding platform 5 is equipped with an auxiliary push plate device 51 for automatically pushing the flooring product toward the feeding backrest and pressing it.

[0074] The four-sided planer 9 is installed at the discharge end of the feeding platform 5.

[0075] Through the implementation of this utility model embodiment, the automated production line for four-sided tongue and groove forming of flooring is arranged sequentially from the production line direction as follows: a double-end milling machine 8, an automatic lifting flow frequency table 1, a double-layer flow frequency table 2, and a flow frequency separation line table 3. Multiple branches are then branched off from the discharge end of the flow frequency separation line table 3. On each branch, from the production line direction, a storage flow frequency table 4, a feeding platform 5, and a four-sided planer 9 are arranged sequentially. This design achieves automated production line integration of one double-end milling machine 8 (double-end milling) and two or more four-sided planer machines 9 (four-sided planing) stations, requiring only 5 people to complete the work. The average daily output per person is approximately 300 square meters, significantly improving production efficiency and effectively reducing costs. Furthermore, in the automated production line, to address the problem of flooring products deviating during the flow frequency transfer process, the following measures are implemented in each major flow frequency... Targeted equipment improvements were made to prevent deviation. Specifically, a first pressure roller 31 for pressing down the floorboards was installed at the end of the flow separation line 3. A conveying adjustment station 42 for floorboard product conveying adjustment was set at the rear end of the storage flow line 4. A feeding support was set along the length of the feeding platform 5, and an auxiliary pusher device 51 was installed to automatically push the floorboards towards the feeding support for pressing. This automatic production line structure and automated devices correct the floorboards, allowing them to smoothly enter the four-sided planer 9. This eliminates the need for dedicated personnel to feed the boards and ensures more stable, faster, and more precise conveying of the floorboards, improving the processing efficiency and quality of the four-sided tongue-and-groove forming process.

[0076] In this embodiment of the invention, a sensor device 11 is provided on the automatic lifting frequency table 1 near the discharge end. When the number of products passing through the sensor reaches a set quantity, the lifting cylinder is activated, automatically lowering or raising the product, and the product is systematically and orderly distributed to two four-sided planer tongue and groove forming machines, and the operation is repeated in this cycle.

[0077] In this embodiment of the invention, the dual-layer flow table 2 includes an upper flow table 21 and a lower flow table 22. Corresponding to the automatic lifting flow table 1, the heights of the upper flow table 21 and the lower flow table 22 are both lower than the height of the automatic lifting flow table 1 when it is in a high position. This allows the automatic lifting flow table 1 to automatically transfer flooring products to the upper flow table 21 and the lower flow table 22. Products from the upper flow table 21 are transferred to the #1 four-sided planer 9, and products from the lower flow table 22 are transferred to the #2 four-sided planer 9.

[0078] More specifically, the upper flow frequency 21 and the lower flow frequency 22 of the dual-layer flow frequency station 2 are each provided with a first support 23 and a first baffle 24. The distance between the first support 23 and the first baffle 24 is 8mm to 15mm larger than the width of the floor product, so that the board can automatically flow from both ends to the four-sided planer and form a straight line. The height of the first support 23 and the first baffle 24 above the height of their respective upper flow frequency 21 and lower flow frequency 22 is 5mm to 10mm, and the height of the first support 23 and the first baffle 24 is less than the thickness of the floor product, so as to prevent the product from flying out of the flow frequency line when abnormalities such as jamming occur.

[0079] In this embodiment of the utility model, the flow frequency separation line 3 is provided with a first pressure roller 31 with bearing near the discharge end. The distance between the bottom of the first pressure roller 31 and the flow frequency separation line 3 is 10mm~12mm. The first pressure roller 31 presses down on the floor product and pushes the board onto the storage flow frequency platform 4 through the flow frequency speed, so as to prevent the floor product from deviating or rushing out of the front end at high speed.

[0080] In this embodiment of the invention, an adjustable baffle block 43 is provided on the front storage station 41 of the material storage flow table 4. The height of the baffle block 43 relative to the flow table is 5mm to 10mm higher than the thickness of a flooring product. The baffle block 43 is inclined at a 45° angle to the material storage flow table 4. The height between the baffle and the flow table is adjusted appropriately according to the thickness of the product being produced, so that the products can enter the next process in an orderly manner. The baffle block 43 is composed of metal and plastic blocks to prevent damage to the ends of the flooring products.

[0081] In this embodiment of the utility model, a second pressure roller 44 and a third pressure roller 45 are sequentially arranged on the conveying adjustment station 42 of the storage flow frequency table 4. The distance between the second pressure roller 44 and the storage flow frequency table 4 is 5mm~10mm, and the distance between the third pressure roller 45 and the storage flow frequency table 4 is 10mm~12mm. The second pressure roller 44 and the third pressure roller 45 press down on the floor product in turn and push the board onto the feeding platform 5 through the flow frequency speed to avoid the floor product from deviating.

[0082] Specifically, the conveying adjustment station 42 has a second support 46 and a second baffle 47, which form a flared opening at a 15° angle to allow for smoother discharge of the flooring products.

[0083] In this embodiment of the utility model, the auxiliary push plate device 51 includes a push plate driving unit 511 and a push plate arm 512. The push plate arm 512 is equipped with a plurality of auxiliary pressure rollers 513 acting on the upper surface of the floor product and a plurality of auxiliary top rollers 514 acting on the side of the floor product. The push plate driving unit 511 periodically drives the push plate arm 512 to move toward the feeding backrest 52 to further prevent the floor product from deviating.

[0084] Furthermore, the length extension direction of the pusher arm 512 is parallel to the feeding backrest. Five auxiliary top rollers 514 are spaced apart on the pusher arm 512. The auxiliary top rollers 514 are spring rubber rollers, and the spacing between the auxiliary top rollers 514 is 190mm~200mm. Four auxiliary pressure rollers 513 are spaced apart on the pusher arm 512. The auxiliary pressure rollers 513 are rubber pressure rollers, and each auxiliary pressure roller 513 is positioned between two auxiliary top rollers 514. This design ensures that before entering the four-sided planer 9, the flooring product is forced to fit tightly against the feeding backrest by the combined action of the auxiliary top rollers 514 and auxiliary pressure rollers 513 on the feeding platform 5. The positions of the auxiliary top rollers 514 and auxiliary pressure rollers 513 are reasonably designed, resulting in a greater effect.

[0085] It should also be noted that the connection and control relationships between the various frequency converters, sensors, auxiliary pusher devices 51 and other equipment and the power supply are not described in detail in this article, as they are all existing technologies.

[0086] The specific implementation process of this utility model embodiment can be referred to as follows:

[0087] 1. Technicians adjust the length of the double-end milling machine 8 and the width and thickness of the four-sided planer 9 according to the specifications and interlocking type of the tongue and groove flooring products to be cut;

[0088] 2. The operator places the flooring product face down into the tongue and groove work point of the double-end milling machine 8. The product passes through the double-end milling machine 8, where it undergoes automatic milling and flows to the automatic lifting flow table 1.

[0089] 3. Automatic lifting frequency table 1, 2 meters long and 1.3 meters wide, frequency flow rate: 45-50 meters / minute. A sensor device 11 is installed 150mm from the end of the frequency table. When the number of products passing through the sensor reaches the set amount, the lifting cylinder is activated, automatically lowering or raising the frequency table, and this cycle continues. Connect the products to the upper / lower double-layer frequency table.

[0090] 4. Upper / lower double-layer flow frequency stage 2, with a height of 980mm. The distance between the upper and lower flow frequencies is 160±5mm, corresponding to the automatic lifting flow frequency stage 1, and both must be lower than the automatic lifting flow frequency stage 1. There are support plates and baffles on both sides of the flow frequency stage. The row of support plates on the right side must be in a straight line. The width of the plates is inconsistent, which is achieved by adjusting the left baffle. The distance between the support plate and the baffle is the actual plate width + 10mm, so that the plate can automatically flow from both ends to the four-sided planer and form a straight line. The height distance between the support plate, baffle, and flow frequency stage is 5mm-10mm, which must be less than the thickness of the flooring product to prevent the flooring product from flying off the flow frequency line in case of machine jamming or other abnormalities. After passing through the upper / lower double-layer flow frequency stage 2, the flooring product is conveyed to the flow frequency separation line stage 3.

[0091] 5. Flow frequency separation line 3, 2.5 meters long. The lower layer is directly pushed down from the lower layer corresponding to the upper / lower double-layer flow frequency platform 2 to the 1.2-meter wide transfer flow frequency platform to the storage flow frequency platform 4 of machine 2. The upper layer is flush with the upper layer flow frequency 21 of the upper / lower double-layer flow frequency, and its left and right sides are consistent with the upper / lower double-layer flow frequency, with a right backrest and baffle plate. At the end of the flow frequency separation line, 100mm away, there is a first pressure roller 31 with a bearing. The first pressure roller 31 is a soft rubber wheel with a diameter of 180mm. The distance between the first pressure roller 31 and the flow frequency is 10mm-12mm. The flow frequency speed is 45-50 meters / minute. The first pressure roller 31 presses down on the floor product and pushes the plate onto the storage flow frequency platform 4 through the flow frequency speed.

[0092] 6. Material storage flow frequency station 4, with a total length of 2.5 meters, a width the same as the upper layer of the flow frequency separation line, and a height 80mm lower than the upper layer of the flow frequency separation line. It is divided into two sections. The front section is the material storage station 41, which is 1.2 meters long. The side baffles are 200mm high. A baffle block 43 is installed 100mm from the end of the right side. The baffle block 43 is composed of iron and plastic blocks (to prevent damage to the end of the plate). The baffle block 43 is 70mm to 75mm wide. The height between the baffle block 43 and the flow frequency is: product thickness + (5mm to 10mm). The baffle plate is inclined at a 45° angle to the flow frequency and can be adjusted up and down. The height between the baffle plate and the flow frequency is adjusted appropriately according to the thickness of the product to facilitate the orderly entry of the product into the next process. The rear conveyor adjustment station 42 has a pressure device with two pneumatic rollers at its upper end, which is 1.3 meters long. The distance between the two rollers is 600mm. The height difference between the second roller 44 and the flow frequency is 5mm-10mm, and the height difference between the third roller 45 and the flow frequency is 10mm-12mm. The third roller 45, located at the rear, should be less forceful than the second roller 44, located at the front, so that the auxiliary pusher device 51 in the subsequent process can push the product to the side. There is a 15° micro-flare at the front 80mm of the right side support plate and the left side baffle plate, which brings the plate into the flow frequency table. The distance between the two baffle plates is the actual width of the product + (4mm-6mm). The flow frequency speed is (45-50) meters / minute. The product is pushed to the feeding platform 5 by the upper rollers and the flow frequency speed.

[0093] 7. Feeding platform 5, 1.8 meters long, is equipped with an auxiliary pusher device 51. The auxiliary pusher device 51 has a 1.2-meter-long pusher arm 512 with bearing spring rubber rollers. It has five movable spring rubber rollers, with a spacing of 190mm-200mm between them and a diameter of (73±1)mm. The distance between the rollers and the right-hand support is the actual product width minus (10mm-12mm). This allows the spring rubber rollers to push the product material straight and horizontally to the right, pressing it tightly against the right-hand support and pushing it into the tongue and groove of the four-sided planer table. Four movable auxiliary pressure rollers 513 are added above the middle of each of the movable spring rubber rollers. The diameter of each auxiliary pressure roller 513 is (60±1)mm, and the height of the rollers relative to the flow frequency is 1mm-2mm less than the product thickness, effectively placing them close to the product. The four vertically added auxiliary pressure rollers 513 prevent product overlap during the pushing process, improving the product loading rate.

[0094] 8. The product enters the four-sided planer forming machine through the feeding platform 5 for tongue and groove processing. Afterwards, one person or a subsequent production line receives the boards, thus completing the entire automated production line process for forming the tongue and groove joints on all four sides of the flooring product.
