Description

Technical Field

[0001] The present invention relates to the technical field of brick-making mechanical equipment, and particularly to a single-board multi-feed board feeder. Background Art

[0002] In building materials production enterprises, when producing products such as ceramics and bricks, the board feeder is an indispensable key equipment. After the brick blanks are dried, they need to be conveyed to subsequent processing stations, and this process requires the board feeder to convey the pallets carrying the brick blanks.

[0003] The existing board feeders generally include a fixed frame, a board feeding mechanism, and a board box. Among them, the board box is arranged on the fixed frame and is used to accommodate multiple layers of pallets. The board feeding mechanism is arranged on the fixed frame and adopts a reciprocating pushing method, responsible for pushing the pallets out of the board box and transporting them to the designated position. The pallets in the board box are used to carry the brick blanks to realize the transportation of the brick blanks.

[0004] However, the existing board feeders have the following technical problems: First, the working efficiency of the existing board feeders is relatively low. Since the board feeding mechanism adopts a reciprocating pushing method and can only convey one pallet at a time, the conveying frequency of the pallets is limited. In actual production, this single-pallet conveying method can no longer meet the requirements of modern production lines for efficiency. Second, in order to improve production efficiency, the existing technology usually adopts the method of replacing large-sized pallets so that a single pallet can carry more brick blanks. However, this method has obvious defects: on the one hand, it is necessary to replace the original pallets, resulting in a waste of equipment resources; on the other hand, due to the change in the pallet size, other equipment supporting the pallets also needs to be replaced accordingly, which greatly increases the equipment investment cost of the enterprise. Summary of the Invention

[0005] The present invention provides a single-board multi-feed board feeder, which can effectively improve the board feeding frequency and processing efficiency without replacing the pallets and related supporting equipment.

[0006] In a first aspect, an embodiment of the present invention provides a single-board multi-feed board feeder, including: a fixed frame, a guide rail is arranged on the fixed frame along a first direction; a board box, arranged on the fixed frame, an outlet for the board is arranged at the bottom of the board box, and the board box is used to accommodate pallets; a first board feeding mechanism, arranged on the fixed frame, the first board feeding mechanism includes a first board feeding component that can slide along the guide rail, and the first board feeding component is located on one side of the board box; a second board feeding mechanism, arranged on the fixed frame, the second board feeding mechanism includes a second board feeding component that can slide along the guide rail, and the second board feeding component is located on the side of the board box away from the first board feeding component and is used to push the pallets in the board box onto the first board feeding component.

[0007] In a possible implementation, the first sheet feeding assembly includes: a first sheet feeding frame; a pushing plate block rotatably arranged on the first sheet feeding frame, and a plurality of pushing plate blocks are arranged at intervals in the first direction. The distance a between two adjacent pushing plate blocks in the first direction satisfies: a > 2b, where b is the length of the pallet in the first direction.

[0008] In a possible implementation, the second sheet feeding assembly includes: a second sheet feeding frame; a pushing plate arranged at one end of the second sheet feeding frame facing the sheet box, and the height of the pushing plate is less than or equal to the height of the bottommost pallet in the sheet box.

[0009] In a possible implementation, the second sheet feeding assembly further includes: a micro-supporting assembly arranged on the second sheet feeding frame for supporting the pallets in the sheet box.

[0010] In a possible implementation, the micro-supporting assembly includes a plurality of first supporting wheels, the axis of the first supporting wheels is perpendicular to the first direction, and the height of the first supporting wheels is greater than the height of the pushing plate.

[0011] In a possible implementation, a plurality of second supporting wheels are arranged on the fixing frame, and the plurality of second supporting wheels are used for supporting the pallets in the sheet box.

[0012] In a possible implementation, a check member is arranged on the fixing frame for restricting the conveyance of the pallet towards the sheet box.

[0013] In a possible implementation, a limiting frame is arranged on the fixing frame along the first direction, and a limiting space is arranged inside the limiting frame. The limiting space is greater than the thickness of a single-layer pallet and less than the thickness of two-layer pallets.

[0016] During the operation of the single-board multi-feed board feeder provided by the present invention, multiple pallet boards are stacked in the board box. The second board feeding mechanism is located on one side of the board box, and the first board feeding mechanism is located on the other side of the board box. The second board feeding mechanism first pushes the bottommost pallet board in the board box onto the first board feeding mechanism, and then returns to prepare to push the next pallet board. When the second board feeding mechanism pushes the second pallet board onto the first board feeding mechanism, the first board feeding mechanism can transport the two pallet boards to the designated position at one time. In this way, multiple pallet boards can be accumulated on the first board feeding mechanism according to actual needs and then transported, solving the problem of low transportation efficiency caused by the fact that the existing board feeder can only transport one pallet board at a time. By setting the cooperation working mode of the two board feeding mechanisms, the present invention enables the second board feeding mechanism to sequentially push multiple pallet boards onto the first board feeding mechanism, and then the first board feeding mechanism transports them at one time, breaking through the limitation that the traditional board feeder can only transport one pallet board at a time and improving the transportation frequency of the pallet boards. Moreover, there is no need to change the pallet board size and related supporting equipment. The production capacity is increased while keeping the original pallet board size unchanged, avoiding the investment waste caused by changing the pallet board and related supporting equipment. Furthermore, without changing the pallet board and related supporting equipment, the feeding frequency of the board can be effectively increased, and the processing efficiency can be improved.

Detailed implementation manners

[0027] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] The following Figure 1-8 describes that an embodiment of the present invention provides a single-board multi-feed sheet feeder, including a fixed frame 1, a sheet box 2, a first sheet feeding mechanism 3 and a second sheet feeding mechanism 4, wherein: The fixed frame 1 is provided with a guide rail 11 along the first direction X. Specifically, the first direction X is a horizontal direction or an inclined direction at a small angle to the horizontal direction.

[0029] The sheet box 2 is arranged on the fixed frame 1. The bottom of the sheet box 2 is provided with a sheet outlet, and the sheet box 2 is used for accommodating the support plate 5.

[0030] The first sheet feeding mechanism 3 is arranged on the fixed frame 1. The first sheet feeding mechanism 3 includes a first sheet feeding assembly 31 that can slide along the guide rail 11, and the first sheet feeding assembly 31 is located on one side of the sheet box 2.

[0031] The second plate feeding mechanism 4 is arranged on the fixed frame 1. The second plate feeding mechanism 4 includes a second plate feeding assembly 41 that can slide along the guide rail 11. The second plate feeding assembly 41 is located on the side of the plate box 2 away from the first plate feeding assembly 31 and is used to push the pallet 5 in the plate box 2 onto the first plate feeding assembly 31.

[0032] During the working process of the plate feeding machine in the present invention, multiple pallets 5 are stacked in the plate box 2. The second plate feeding mechanism 4 is located on one side of the plate box 2, and the first plate feeding mechanism 3 is located on the other side of the plate box 2. The second plate feeding mechanism 4 first pushes the bottommost pallet 5 in the plate box 2 onto the first plate feeding mechanism 3, and then returns to prepare to push the next pallet 5. When the second plate feeding mechanism 4 pushes the second pallet 5 onto the first plate feeding mechanism 3, the first plate feeding mechanism 3 can transport the two pallets 5 to the designated position at one time. In this way, multiple pallets 5 can be accumulated on the first plate feeding mechanism 3 according to actual needs and then transported, solving the problem of low transportation efficiency caused by the fact that the existing plate feeding machine can only transport one pallet 5 at a time. By setting the cooperation working mode of the two plate feeding mechanisms in the present invention, the second plate feeding mechanism 4 can push multiple pallets 5 onto the first plate feeding mechanism 3 in sequence, and then the first plate feeding mechanism 3 transports them at one time, breaking through the limitation that the traditional plate feeding machine can only transport one pallet 5 at a time and improving the transportation frequency of the pallet 5. Moreover, without changing the size of the pallet 5 and related supporting equipment, the production capacity is increased while keeping the original size of the pallet 5 unchanged, avoiding the investment waste caused by replacing the pallet 5 and related supporting equipment. Furthermore, without replacing the pallet 5 and related supporting equipment, the feeding frequency can be effectively increased and the processing efficiency can be improved.

[0033] Specifically, a smooth support rail 15 is arranged on the fixed frame 1 to support the pallet 5 during transportation through the smooth support rail 15, reducing the friction force received by the pallet 5 during transportation. Optionally, a conveying wheel can also be arranged on the fixed frame 1 to enable the pallet 5 to be conveyed along the conveying wheel. Only part of the first plate feeding mechanism 3 is shown in the drawings of the present invention. In an actual production line, multiple groups of the first plate feeding mechanism 3 will be arranged, and the multiple groups of the first plate feeding mechanism 3 are arranged continuously to ensure the conveying length of the pallet 5, so as to facilitate multi-faceted processing of the green bricks on the pallet 5.

[0034] In the related art, when a higher production capacity is required in a brick blank production line, traditional solutions usually require replacing the pallet 5 with a larger size and related supporting equipment. However, the replacement of the pallet 5 and related supporting equipment greatly increases the equipment investment cost of the enterprise. In this solution, by arranging two independent first pallet feeding mechanisms 3 and second pallet feeding mechanisms 4 on the fixed frame 1, the production capacity can be improved without replacing the original pallet 5. The specific working process is as follows: The second pallet feeding mechanism 4 sequentially pushes the pallets 5 in the pallet box 2 onto the first pallet feeding mechanism 3. When a predetermined number of pallets 5 are accumulated on the first pallet feeding mechanism 3, multiple pallets 5 are transported to the target position at one time.

[0035] Since the first pallet feeding mechanism 3 and the second pallet feeding mechanism 4 are respectively located on both sides of the pallet box 2, forming an opposed layout, the conveying path of the pallet 5 is linear, reducing the number of turns of the pallet 5 during conveying. In actual production, the turning of the pallet 5 easily causes the position deviation of the pallet 5 or the dropping of the brick blanks on the pallet 5, and the linear conveying path of this solution effectively avoids these problems.

[0036] This solution has significant economic benefits in practical applications: Taking a production line with an annual output of 100 million standard bricks as an example, after adopting this solution, the production capacity can be increased to 150 - 200 million pieces / year without replacing the original pallet 5. Compared with the traditional solution of replacing the large-size pallet 5, about 1.5 million yuan of equipment investment can be saved.

[0037] In some embodiments, the first pallet feeding assembly 31 includes: a first pallet feeding frame 311; a pushing plate block 312 rotatably arranged on the first pallet feeding frame 311, and a plurality of pushing plate blocks 312 are arranged at intervals along the first direction X. The distance a between two adjacent pushing plate blocks 312 along the first direction X satisfies: a > 2b, where b is the length of the pallet 5 along the first direction X.

[0038] In the present invention, the pushing plate block 312 adopts a rotatable design. When the pallet 5 contacts the pushing plate block 312 during conveying, the pushing plate block 312 can automatically flip by a certain angle to enable the pallet 5 to pass smoothly. When the second pallet feeding assembly 41 pushes the pallet 5 onto the first pallet feeding assembly 31, if the pushing plate block 312 is fixed, the pallet 5 cannot cross the pushing plate block 312; while adopting the rotatable design, the pallet 5 can easily pass, and after the pallet 5 passes, the pushing plate block 312 automatically resets under the action of gravity.

[0039] The distance design of the pushing plate blocks 312 (a > 2b) ensures that at least two pallets 5 can be placed between two adjacent pushing plate blocks 312. This distance design enables the first pallet feeding assembly 31 to accommodate multiple pallets 5 at the same time. For example: When the length of the pallet 5 is 1200 mm, the distance between adjacent pushing plate blocks 312 is at least 2400 mm, so that two pallets 5 can be placed between two pushing plate blocks 312, providing a space basis for realizing the simultaneous conveying of multiple pallets 5.

[0040] Optionally, when it is required that the first plate feeding assembly 31 can push three pallets 5 simultaneously, it is only necessary to make a > 3b. Similarly, this plate feeding machine can realize the single - time transportation of multiple pallets 5.

[0041] During the actual operation of the production line, due to the large spacing between the pushing plates 312, the number of the pushing plates 312 is reduced, thereby reducing the equipment manufacturing cost and the later maintenance cost. At the same time, the rotatable design of the pushing plates 312 reduces the wear between the pallet 5 and the pushing plates 312, and extends the service life of the equipment.

[0042] Specifically, the pushing plates 312 are grouped in pairs. One group of pushing plates 312 is arranged in a direction perpendicular to the first direction X, so that the two pushing plates 312 jointly push the pallet 5 to move, which can ensure the stability of the pallet 5 during the transportation process. The pushing plates 312 are connected to the first plate feeding frame 311 in a rotatable form. The first plate feeding frame 311 is provided with limit blocks for limiting the pushing plates 312, so as to limit the pushing plates 312 in the clockwise direction to ensure that the pushing plates 312 can push the pallet 5 to move; when the second plate feeding assembly 41 pushes the pallet 5 onto the first plate feeding frame 311, or when the second plate feeding frame 411 moves towards the plate box 2, the pushing plates 312 can rotate counter - clockwise, so that the pallet 5 can smoothly cross the pushing plates 312.

[0043] In some embodiments, the second plate feeding assembly 41 includes: a second plate feeding frame 411; a pushing plate 412, which is arranged at one end of the second plate feeding frame 411 facing the plate box 2, and the height of the pushing plate 412 is less than or equal to the height of the bottom - most pallet 5 in the plate box 2.

[0044] In the present invention, the height of the pushing plate 412 is designed to be less than or equal to the height of the bottom - most pallet 5 in the plate box 2. This design ensures that the pushing plate 412 can only push the bottom - most pallet 5. In actual production, there are usually multiple layers of pallets 5 (about 10 - 15 layers) stacked in the plate box 2. If the height of the pushing plate 412 is too high, it may push multiple layers of pallets 5 simultaneously, resulting in chaotic stacking of the pallets 5. However, this design realizes the precise separation and pushing of the pallets 5 by controlling the height of the pushing plate 412.

[0045] Specifically, when the thickness of the pallet 5 is 50 mm, the height of the pushing plate 412 is designed to be 45 - 50 mm. During the pushing process, the pushing plate 412 is exactly below the bottom - most pallet 5, and the upper - layer pallets 5 fall naturally due to gravity. However, since they have not completely fallen into place, at this time, the pushing plate 412 has pushed out the bottom - most pallet 5, realizing the individual separation of the pallets 5.

[0046] In some embodiments, the second plate feeding assembly 41 further includes: a micro - pallet assembly 413, which is arranged on the second plate feeding frame 411 and is used to support the pallets 5 in the plate box 2.

[0047] In the present invention, by providing a micro-support assembly 413 on the second plate feeding rack 411, during the process of the push plate 412 pushing the bottommost pallet 5 out of the pallet box 2, other pallets 5 in the pallet box 2 can be supported to prevent the pallets 5 from falling and interfering with the reset of the push plate 412.

[0048] Specifically, when the push plate 412 pushes the bottommost pallet 5 in the pallet box 2, it penetrates through the pallet box 2, so that the pallet 5 can be pushed onto the first plate feeding rack 311 and pass over the nearest push block 312. At this time, the other pallets 5 in the pallet box 2 are temporarily supported by the micro-support assembly 413 to ensure that the push plate 412 can be reset smoothly. When the push plate 412 pushes the second pallet 5, the second pallet 5 pushes the first pallet 5 on the first plate feeding rack 311, so that the two pallets 5 pass over the push block 312, realizing that a set of push blocks 312 of the first push plate assembly can push two pallets 5. When the first plate feeding mechanism 3 moves reciprocally, the step-by-step conveyance of two pallets 5 can be realized. The same applies to three or more pallets 5.

[0049] In a specific embodiment, currently, in order to ensure the stability of the push of the pallet 5 by the first plate feeding assembly 31 and the distance of a single reciprocating movement of the first plate feeding mechanism 3, generally, a set of push blocks 312 can push two pallets 5.

[0050] In some embodiments, the micro-support assembly 413 includes a plurality of first support wheels 4131. The axis of the first support wheel 4131 is perpendicular to the first direction X, and the height of the first support wheel 4131 is greater than the height of the push plate 412.

[0051] In the present invention, the micro-support assembly 413 supports the pallets 5 in the pallet box 2 through a plurality of first support wheels 4131. In actual production, when the push plate 412 pushes out the bottommost pallet 5, the upper pallets 5 will fall naturally. Without a support mechanism, the upper pallets 5 will directly press on the push plate 412, increasing the load and friction of the push plate 412. After the micro-support assembly 413 is provided, the upper pallets 5 are supported by the first support wheels 4131, reducing the contact with the push plate 412.

[0052] Specifically, the design that the height of the first support wheel 4131 is greater than the height of the push plate 412 ensures that the push plate 412 will not interfere with the upper pallets 5 during the pushing and retracting processes. In practical applications, if the height of the push plate 412 is 45 mm, the height of the first support wheel 4131 can be designed to be 55 mm, which can not only ensure the stable support of the pallets 5 but also not affect the operation of the push plate 412.

[0053] Moreover, the arrangement of multiple first support wheels 4131 also reduces the friction between the pallets 5. In production practice, pallets 5 are usually made of cast iron, steel plates, templates or PVC plates. If directly stacked, the friction between the pallets 5 is very large. However, through the rolling support of the first support wheels 4131, the friction is greatly reduced, making the movement of the pallets 5 smoother.

[0054] In some embodiments, a plurality of second support wheels 12 are provided on the fixing frame 1, and the plurality of second support wheels 12 are used to support the pallets 5 in the pallet box 2.

[0055] In the present invention, the second support wheels 12 are provided on the fixing frame 1 and are used to support the pallets 5 in the pallet box 2. In actual production, the total weight of the pallets 5 in the pallet box 2 can reach 500 - 800 kg. Without a support structure, the pallets 5 rely entirely on stacking, and the pressure on the bottom pallet 5 is very large, which is not conducive to the pushing of the push plate 412. After the second support wheels 12 are provided, part of the weight is borne by the second support wheels 12, reducing the pressure on the bottom pallet 5 and the friction when the pallet 5 is pushed out of the pallet box 2, facilitating the pushing of the pallet 5 out of the pallet box 2.

[0056] Specifically, the uniform distribution of the plurality of second support wheels 12 ensures uniform force on the pallets 5. In practice, usually a second support wheel 12 is provided every 300 - 400 mm, which can prevent the pallets 5 from deforming or being damaged during the support process. The rolling characteristics of the support wheels also make the movement of the pallets 5 smoother and reduce energy consumption.

[0057] In some embodiments, a check member 13 is provided on the fixing frame 1 for restricting the conveyance of the pallet 5 towards the pallet box 2.

[0058] In the present invention, the check member 13 is installed on the fixing frame 1 to prevent the pallet 5 from moving in the reverse direction during conveyance. In actual production, when the first pallet feeding assembly 31 moves back, due to inertia, the pallet 5 may move accordingly. After the check member 13 is provided, the pallet 5 can only move forward, ensuring the unidirectionality of the conveyance.

[0059] Specifically, the check member 13 adopts a one-way rotation structure. When the pallet 5 moves forward, the check member 13 can rotate without affecting the passage of the pallet 5; when the pallet 5 moves in the reverse direction, the check member 13 blocks the pallet 5 to prevent reverse movement. This design is simple and reliable and easy to maintain.

[0060] In some embodiments, a limiting frame 14 is provided on the fixing frame 1 along the first direction X. A limiting space 141 is provided inside the limiting frame 14. The limiting space 141 is larger than the thickness of a single-layer pallet 5 and smaller than the thickness of two layers of pallets 5.

[0061] In the present invention, the limiting frame 14 is arranged along the conveying direction, and the limiting space 141 inside it is larger than the thickness of a single pallet 5 but smaller than the thickness of two pallets 5. This design plays an important role in actual production: when multiple pallets 5 are conveyed, without a limiting structure, the pallets 5 may be stacked, resulting in jamming or damage. However, through the precise control of the limiting space 141, even if the pallets 5 bounce during the conveying process, stacking will not occur.

[0062] Taking the actual size as an example: when the thickness of the pallet 5 is 50 mm, the limiting space 141 can be designed to be 55 - 95 mm. Such a design not only ensures that a single pallet 5 can pass through smoothly but also effectively prevents the pallets 5 from being stacked. In production practice, this design greatly improves the reliability of conveying and reduces equipment failures and maintenance times.

[0063] Specifically, there are two limiting frames 14, and the two limiting frames 14 are arranged oppositely on the fixed frame 1. The limiting frame 14 is an angle steel. The oppositely arranged limiting frames 14 can not only limit the pallet 5 in the height direction to prevent the pallets 5 from being stacked or warped but also limit the two ends of the pallet 5 to prevent the pallet 5 from being deflected during the conveying process, ensuring the consistency of the position of the pallet 5 perpendicular to the first direction X and facilitating the subsequent supporting equipment to use the pallet 5.

[0064] In some embodiments, the first pallet conveying assembly 31 includes a plurality of first pulleys 313 arranged at intervals along the first direction X, and the plurality of first pulleys 313 are slidably engaged with the guide rail 11 to form a first pulley group; the second pallet conveying assembly 41 includes a plurality of second pulleys 414 arranged at intervals along the first direction X, and the plurality of second pulleys 414 are slidably engaged with the guide rail 11 to form a second pulley group.

[0065] In the present invention, the first pulley group and the second pulley group are respectively slidably engaged with the guide rail 11 to realize the smooth movement of the first pallet conveying assembly 31 and the second pallet conveying assembly 41. In actual production, the weight of the first pallet conveying assembly 31 and the second pallet conveying assembly 41 plus the weight of the pallet 5 can reach 100 - 150 kg. If a slider structure is adopted, the frictional force is large and a larger power output is required. However, by adopting a pulley group design, rolling friction is used instead of sliding friction, greatly reducing the movement resistance. The high-frequency reciprocating movement of the first pallet conveying mechanism 3 and the second pallet conveying mechanism 4 can effectively reduce energy consumption.

[0066] Specifically, the plurality of first pulleys 313 and the plurality of second pulleys 414 are arranged at intervals along the conveying direction, ensuring the stability of the movement of the first pallet conveying assembly 31 and the second pallet conveying assembly 41. In practice, usually a pulley is arranged every 600 - 800 mm. This layout not only ensures the bearing capacity but also avoids the tilting or shaking of the pallet conveying assembly during the movement.

[0067] In some embodiments, the first sheet feeding mechanism 3 includes a first power unit 32 for driving the first sheet feeding assembly 31 to reciprocate along the guide rail 11; and / or, the second sheet feeding mechanism 4 includes a second power unit 42 for driving the second sheet feeding assembly 41 to reciprocate along the guide rail 11.

[0068] In the present invention, the first power unit 32 and the second power unit 42 respectively drive the corresponding sheet feeding assemblies to reciprocate. In actual production, different types of power units can be selected according to specific requirements: for occasions requiring large thrust, a hydraulic cylinder can be selected; for occasions requiring fast response, a pneumatic cylinder can be selected; for occasions requiring precise control, a motor can be used in combination with a transmission mechanism.

[0069] Specifically, the independent setting of the two power units enables the two sheet feeding assemblies to work in coordination. In practice, the action timing of the two power units can be adjusted through a control system to achieve continuous conveyance of the pallet 5. For example: when the second sheet feeding assembly 41 completes one push, the first sheet feeding assembly 31 remains stationary; when a predetermined number of pallets 5 accumulates, the first sheet feeding assembly 31 then conveys. This coordinated cooperation improves the conveyance efficiency and reduces the chance of collision between the pallets 5.

[0070] During the working process of the single-sheet multi-feed sheet feeding machine provided by the embodiment of the present invention, multiple layers of pallets 5 are stacked in the sheet box 2. The second sheet feeding mechanism 4 is located on one side of the sheet box 2, and the first sheet feeding mechanism 3 is located on the other side of the sheet box 2. The second sheet feeding mechanism 4 first pushes the lowermost pallet 5 in the sheet box 2 onto the first sheet feeding mechanism 3, and then returns to prepare to push the next pallet 5. When the second sheet feeding mechanism 4 pushes the second pallet 5 onto the first sheet feeding mechanism 3, the first sheet feeding mechanism 3 can convey the two pallets 5 to the designated position at one time. In this way, multiple pallets 5 can be accumulated on the first sheet feeding mechanism 3 according to actual needs before conveyance, solving the problem of low conveyance efficiency caused by the existing sheet feeding machine being able to convey only one pallet 5 at a time. By setting the cooperation working mode of the two sheet feeding mechanisms, the second sheet feeding mechanism 4 can push multiple pallets 5 onto the first sheet feeding mechanism 3 in sequence, and then the first sheet feeding mechanism 3 conveys them at one time, breaking through the limitation that the traditional sheet feeding machine can only convey one pallet 5 at a time, and improving the conveyance frequency of the pallets 5. Moreover, without changing the size of the pallet 5 and related supporting equipment, the production capacity is increased while keeping the original size of the pallet 5 unchanged, avoiding the investment waste caused by replacing the pallet 5 and related supporting equipment, and thus effectively improving the sheet feeding frequency and processing efficiency without replacing the pallet 5 and related supporting equipment.

[0071] The first board feeding mechanism and the second board feeding mechanism of the present invention form a complete "push - support - feed" conveying chain. Specifically, the push board of the second board feeding mechanism pushes the pallet out of the board box. At this time, the support system formed by the micro - support component and the second support wheel supports the remaining pallets. The pushed - out pallet is unidirectionally conveyed under the cooperation of the rotatable push plate block and the check member, ensuring that the pallet does not move in the reverse direction. This structural design makes the pallet conveying process smoother and more reliable, effectively avoiding the situation of pallet jamming or damage during the conveying process.

[0072] In terms of motion control, the two power units achieve precise cooperation through the control system. When multiple pallets need to be conveyed, the second board feeding mechanism pushes the pallets to the first board feeding mechanism one by one according to a preset rhythm. For example, during the use of a brick and tile production line, the second board feeding mechanism first pushes the first pallet onto the first board feeding mechanism, and then returns to prepare to push the second pallet. During this process, the first board feeding mechanism remains stationary until a predetermined number of pallets are accumulated. This coordinated motion not only improves the conveying efficiency but also reduces the chance of collision between pallets.

[0073] To ensure the safe and reliable operation of the equipment, the present invention designs multiple protection mechanisms. The limit frame prevents the pallets from being stacked during the conveying process through a reasonable limit space design; the double - support system formed by the micro - support component and the second support wheel ensures the stable conveying of the pallets; the check member prevents the pallets from moving in the reverse direction. These protection measures cooperate with each other in actual production, significantly improving the reliability of the equipment. For example, the board feeding machine of a certain building materials enterprise adopting this solution did not have any failures during continuous operation for 3 months, while the average monthly maintenance times of the same - type traditional board feeding machine were 2 - 3 times.

[0074] The present invention also has remarkable effects in saving production costs. First, due to the use of a pulley - block structure to reduce the friction between moving parts, a power unit with a smaller power can be selected, reducing the energy consumption of the equipment. Second, the design of the rotatable push plate block reduces the wear between parts, extends the service life of the equipment, and reduces the maintenance cost. Most importantly, the present invention can improve the production capacity without replacing the original pallets and supporting equipment, greatly reducing the equipment investment cost of the enterprise.

[0075] In terms of actual production efficiency, the effect of the present invention has also been fully verified. Taking a building materials production enterprise as an example, after adopting the board feeding machine of the present invention, the daily production capacity has increased from the original 80,000 pieces to 140,000 pieces, with an increase rate of 75%. At the same time, the degree of automation of the equipment has increased, and the number of operators per shift has decreased from the original 3 to 1, significantly reducing the labor cost. In addition, due to the adoption of an efficient conveying method, the energy consumption per unit product has also been reduced by about 30%.
