TECHNICAL FIELD

[0001] The application belongs to the technical field of hot pressing, and particularly relates to a hot pressing material pushing device. BACKGROUND

[0002] Hot pressing is a process of heating and pressing the material after being laid and formed to produce a material product with certain mechanical strength and water resistance. Whether it is wet production of hard products or semi-hard products, or dry production of hard products or medium-density products, hot pressing is required to form the products. During hot pressing of the material product, the material needs to be pushed.

[0003] In the prior art (patent application with the patent name of a protective device for a conveying belt of a telescopic table skin hot pressing machine, and the announcement number CN222699269U), the hinge can be prevented from being exposed, and the surface of the plate can be cleaned during conveying. In the process of implementing the technical solution, it is found that at least the following problems exist in the prior art.

[0004] During the pushing and conveying of the material, the material is directly pushed and conveyed by the conveying belt or the conveying roller. During this period, due to the influence of the friction coefficient of the surface of the material, the material is prone to short-term idle stop during the pushing and conveying of the material. The material cannot be mechanically pulled and fed based on the premise of stable limitation, and the conveying site cannot be simultaneously cleaned and wiped. SUMMARY

A winding frame is fixedly connected to both sides of the horizontal shaft, and a steel wire rope for pulling and feeding the material on the placement table is wound on the winding frame.

[0011] Preferably, the limiting assembly further includes ratchet wheels fixed at both ends of the horizontal shaft, and one side of the ratchet wheel is engaged with a pawl that is hinged to the fixed cover and fixedly connected to the dial head. The outer side of the pawl is fixedly connected with a limiting spring that is fixedly engaged with the fixed cover. The inner cavity of the conveyor frame is rotatably connected with a rotating rod. A spring ring that is fixedly engaged with the conveyor frame is sleeved at the center of the rotating rod, and both sides of the rotating rod are fixedly connected with a stopper that is limited by the placement platform.

[0012] Preferably, the cleaning assembly further includes a main sprocket meshing with the inner side of the teeth and rotating with the placement platform, and a driven sprocket meshing with the placement platform on one side of the main sprocket. A cleaning disc that cooperates with the conveyor frame is fixedly connected to the bottom of the main sprocket, and a scraping strip that cooperates with the conveyor frame is fixedly connected to the bottom of the driven sprocket. An exhaust fan is fixedly connected to the top of both the main sprocket and the driven sprocket, and a flow equalization net for use with the exhaust fan is embedded around the top of the placement platform.

[0013] Preferably, the conveyor frame has a transverse groove on the side near the baffle that is in contact with the stop member, and a main slide and a secondary slide that are fixedly connected to the placement platform and in contact with the stop member are slidably connected in the transverse groove. The main slide is fixed to the end of the wire rope.

[0014] Preferably, a limiting head is fixedly connected to the outer side of the main carriage, and a return spring that is fixedly connected inside the limiting head and is fixedly engaged with the conveyor frame.

[0017] Preferably, the main sprocket and the driven sprocket adopt a one-to-one transmission design and do not mesh with each other, and the bottom of the sweeping disc is attached to the sweeping cloth by Velcro, and the scraping strips are distributed in a triangular equidistant shape.

[0018] Preferably, the top of the placement platform is provided with air collection chambers that communicate and cooperate with the exhaust fan and the air distribution network, and the placement platform is provided with ventilation ducts that communicate and cooperate with the air collection chambers, and the ventilation ducts are provided with ventilation holes.

[0019] The hot-pressing feeding device of the present invention has the following advantages:

[0020] 1. This hot-press material feeding device first adjusts the meshing stroke between the first main gear and the first auxiliary gear to the correct position using a first electric push rod. Then, a double-headed motor drives the winding frames at both ends of the horizontal shaft to rotate synchronously through the meshed first main gear and the first auxiliary gear. The two sets of winding frames wind and unwind two steel wire ropes. At the same time, the rotating horizontal shaft drives the pawls on the two sets of ratchet wheels to skip teeth under the support of two limit springs, achieving a reverse restriction effect on the winding frames at both ends of the horizontal shaft. The reverse restriction of the winding frames is manually released by the dial head, improving the material feeding stability on the placement platform. Furthermore, the spring coils on several arrayed rotating rods provide elastic limit and elastic reset for the abutment components. These abutment components provide equidistant restriction on the placement platform in the material feeding state to prevent reverse displacement and slippage, further improving the material feeding stability on the placement platform. Based on the premise of stable restriction, the material is mechanically traction fed.

[0021] 2. In this hot-press material feeding device, the two sets of main spur gears, driven by two rows of teeth meshing with the two sets of main spur gears, rotate as the platform moves. These main spur gears then drive two sets of driven spur gears to rotate, which in turn drives two sets of cleaning discs to clean the conveyor frame. Simultaneously, the driven spur gears drive scraping strips to wipe the conveyor frame. At the same time, the main and driven spur gears drive exhaust fans to rotate. The rotating exhaust fans generate airflow within the air collection chamber, which is then evenly blown onto the material area on the platform by a flow equalization net. This provides auxiliary heat dissipation for the material and also cleans the platform and the material on it. Furthermore, the airflow within the air collection chamber is blown through ventilation holes to the surrounding area of ​​the material on the platform, further enhancing heat dissipation and cleaning, thus improving the cleanliness of the material during transport and the overall cleanliness of the conveyor frame.

[0022] 3. In this hot-press material feeding device, the meshing stroke between the second main gear and the second auxiliary gear is first adjusted by the second electric push rod. Then, the double-headed motor drives the turntable on the vertical shaft to rotate through the meshed second main gear and the second auxiliary gear. The turntable drives the swing frame to swing back and forth horizontally. The swing frame swings back and forth horizontally, and the support arm on the three-stage electric cylinder moves accordingly through the sliding parts. The three-stage electric cylinder adjusts the height of the two sets of electric suction cups through the support arm. At the same time, the swinging support arm drives the two sets of electric suction cups to alternately stack and place the material on the delivery platform, achieving a fast and orderly feeding effect. During this period, the position sensor monitors the alternating displacement of the two sets of electric suction cups in real time, and the industrial camera tracks and re-inspects the material adsorption and stacking of the two sets of electric suction cups in real time to ensure the accuracy of material stacking.

[0044] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0045] like Figures 1-19 As shown, a hot pressing feeding device of the present invention includes a conveying frame 1, with baffles 2 fixedly connected to both sides of the top of the conveying frame 1, and a placement platform 3 that slides and cooperates with the baffles 2 slidably connected to the feeding part of the conveying frame 1, a fixing cover 4 fixedly connected to the outer side of the conveying frame 1 near the placement platform 3, a pre-inspection platform 5 fixedly connected to the unloading part of the conveying frame 1, and a processor 6 fixedly connected to one side of the inner cavity of the conveying frame 1.

[0046] The inner cavity of the conveyor frame 1 is equipped with a traction component for mechanical feeding with the placement platform 3, and the traction component includes a double-headed motor 71 embedded in one side of the inner cavity of the conveyor frame 1; the conveyor frame 1 and the fixed cover 4 are equipped with a limiting component that cooperates with the traction component, and the limiting component includes a dial 84 that rotates outside the fixed cover 4. Under the premise of stable limitation, the material is mechanically traction fed. The placement platform 3 is equipped with a cleaning component that cooperates with the conveyor frame 1 for cleaning, and the cleaning component includes teeth 91 arrayed and embedded in the inner side of the baffle 2. While cleaning and wiping the conveyor frame 1, it also plays an auxiliary role in heat dissipation and blowing and cleaning the material.

[0047] like Figures 5-13As shown, the traction assembly also includes a first electric push rod 72 embedded in one output shaft of the dual-head motor 71, and a first main gear 73 is fixedly connected to the first electric push rod 72. A first auxiliary gear 74 is provided on the outside of the first main gear 73, and a horizontal shaft 75 that rotates with the conveyor frame 1 and the fixed cover 4 is fixedly connected to the inner cavity of the first auxiliary gear 74. Both sides of the horizontal shaft 75 are fixedly connected to the winding frames 76. After the first electric push rod 72 adjusts the meshing stroke between the first main gear 73 and the first auxiliary gear 74 to the correct position, the dual-head motor 71 drives the winding frames 76 at both ends of the horizontal shaft 75 to rotate synchronously through the meshed first main gear 73 and the first auxiliary gear 74. The winding frames 76 are wound with steel wire ropes 77 for the placement platform 3 to pull and feed materials. The two sets of winding frames 76 perform winding and unwinding actions on the two steel wire ropes 77.

[0048] The limiting assembly also includes ratchet wheels 81 fixed at both ends of the horizontal shaft 75. One side of each ratchet wheel 81 is engaged with a pawl 82 hinged to the fixed cover 4 and fixedly connected to the dial head 84. A limiting spring 83, fixedly engaged with the fixed cover 4, is fixedly connected to the outer side of the pawl 82. When the horizontal shaft 75 rotates, the pawls 82 on the two sets of ratchet wheels 81, supported by the two limiting springs 83, perform a skipping action, achieving a reverse limiting effect on the winding frames 76 at both ends of the horizontal shaft 75. The dial head 84 manually releases the reverse action of the winding frames 76, improving the material handling on the placement table 3. To improve conveying stability, the inner cavity of the conveyor frame 1 is rotatably connected with rotating rods 85. A spring coil 86 fixedly engages with the conveyor frame 1 at the center of the rotating rod 85. Both sides of the rotating rod 85 are fixedly connected with stoppers 87 that restrict the placement platform 3. The spring coils 86 on the array of rotating rods 85 provide elastic limiting and elastic reset for the stoppers 87. The stoppers 87 provide equidistant restriction for the placement platform 3 in the material feeding and conveying state, so as to prevent the placement platform 3 from sliding in the opposite direction, and further improve the material feeding and conveying stability on the placement platform 3.

[0049] A transverse groove 12 is provided on the side of the conveyor frame 1 near the baffle 2, which is through-fitted with the stop member 87. A main slide 13 and a secondary slide 14, which are fixedly fitted to the placement platform 3, are slidably connected within the transverse groove 12 and are also through-fitted with the stop member 87, providing sliding support for the placement platform 3 and improving the material conveying stability of the placement platform 3. The main slide 13 is fixed to the end of the wire rope 77. A limit head 15 is fixedly connected to the outside of the main slide 13, and a return spring 16, which is fixedly fitted to the conveyor frame 1, is fixedly connected inside the limit head 15. The main slide 13 provides elastic buffering and reset for the placement platform 3. Both sides of the platform 3 are provided with slide rails 17 that slide with the baffle 2, which play a sliding limit role on the side of the platform 3 to prevent the platform 3 from shaking during the pulling displacement. The rotating rod 85 is fixed diagonally on both sides near the stop member 87 with abutment heads 18 that abut with the conveyor frame 1, which play a stop limit role on the stop member 87. The side of the platform 3 near the main slide 13 and the auxiliary slide 14 is provided with abutment groove 19 that is used in conjunction with the stop member 87. The abutment groove 19 is distributed in an inclined state to guide the stop member 87 downward to prevent jamming between the platform 3 and the stop member 87.

[0050] The cleaning assembly also includes a main sprocket 92 meshing with the inner side of the teeth 91 and rotating with the placement platform 3. Under the meshing transmission of the two sets of main sprockets 92 by the two rows of teeth 91, the two sets of main sprockets 92 rotate as the placement platform 3 moves. One side of each main sprocket 92 meshes with a driven sprocket 93 that rotates with the placement platform 3. The two sets of main sprockets 92 drive the two sets of driven sprockets 93 to rotate accordingly. A cleaning disc 94 that cleans the conveyor frame 1 is fixedly connected to the bottom of each main sprocket 92. The two sets of main sprockets 92 drive the two sets of cleaning discs 94 to clean the conveyor frame 1. The bottom of the driven sprocket 93 is fixedly connected with... The conveyor frame 1 is wiped clean with the cleaning strip 95. Two sets of driven spur gears 93 drive the cleaning strip 95 to wipe the conveyor frame 1. The top of the main spur gear 92 and the driven spur gear 93 are fixedly connected with exhaust fans 96. The top of the placement platform 3 is embedded with flow equalization nets 97 that are used in conjunction with the exhaust fans 96. The two sets of main spur gears 92 and the two sets of driven spur gears 93 drive the exhaust fans 96 to rotate. The rotating exhaust fans 96 generate wind in the air collection chamber 20 and are evenly blown onto the material area on the placement platform 3 by the flow equalization nets 97. This not only helps to cool the material but also achieves the effect of blowing and cleaning the placement platform 3 and the material on it.

[0051] The main sprocket 92 and the driven sprocket 93 adopt a one-to-one transmission design and do not mesh with each other. This facilitates the one-to-one drive of the driven sprocket 93 by the main sprocket 92 to rotate in sections. The bottom of the sweeping disc 94 is attached to a sweeping cloth via Velcro, which facilitates cleaning and replacement of the sweeping cloth and improves the cleaning effectiveness of the sweeping disc 94 on the conveyor frame 1. The scraping strips 95 are distributed in a triangular, equidistant pattern, simultaneously sweeping and wiping the conveyor frame 1. The four... The platform 3 is provided with an air collection chamber 20 that is connected and cooperates with the exhaust fan 96 and the flow equalization net 97. The exhaust fan 96 rotates in the air collection chamber 20 and generates air force. The air force is then blown out by the flow equalization net 97. The platform 3 is provided with a ventilation duct 21 that is connected and cooperates with the air collection chamber 20. The ventilation duct 21 is provided with ventilation holes 22. The air force generated in the air collection chamber 20 reaches the ventilation duct 21 and is then blown out by the ventilation holes 22, which plays an auxiliary role in blowing and cooling the platform 3 and the materials on it.

[0052] like Figures 14-18 As shown, after the material is fed and transported, the material is mostly unloaded manually. Alternating stacking is not possible for rapid and orderly unloading, which is time-consuming, labor-intensive, and inefficient. The pre-inspection station 5 is equipped with alternating and stacking components used in conjunction with an external material feeding box. The alternating component includes a second electric push rod 101 embedded in the other output shaft of the dual-head motor 71. A second main gear 102 is fixedly connected to the second electric push rod 101, and a second auxiliary gear 103 is located on the outer side of the second main gear 102. The top of 103 is fixedly connected to a vertical shaft 104 that rotates with the pre-inspection table 5. The top of the vertical shaft 104 is fixedly connected to a turntable 105. First, the second electric push rod 101 adjusts the meshing stroke between the second main gear 102 and the second auxiliary gear 103 to the correct position. Then, the double-head motor 71 drives the turntable 105 on the vertical shaft 104 to rotate through the meshed second main gear 102 and the second auxiliary gear 103. A swing frame 106 is slidably connected to the turntable 105 through a protrusion. The turntable 105 drives the swing frame 106 to swing back and forth horizontally.

[0053] The stacking assembly includes a sliding member 111 fixed on the swing frame 106 and slidingly engaged with a pre-reserved opening on the pre-inspection table 5. A three-stage electric cylinder 112 is fixedly connected to one side of the sliding member 111, and a support arm 113 is fixedly connected to the bottom of the three-stage electric cylinder 112. The horizontally swinging swing frame 106 drives the support arm 113 on the three-stage electric cylinder 112 to move accordingly through the sliding member 111. Both sides of the support arm 113 are fixedly connected to electric suction cups 114 that cooperate with the external material feeding box. The three-stage electric cylinder 112 adjusts the height of the two sets of electric suction cups 114 through the support arm 113, while the horizontally swinging support arm also adjusts the height of the two sets of electric suction cups 114. 113 drives two sets of electric suction cups 114 to alternately stack and place the materials on the placement table 3, which is delivered to the position, thus achieving a fast and orderly unloading function. A position sensor 115 is fixedly connected to the center of the support arm 113, and an industrial camera 116 is fixedly connected to both sides of the position sensor 115. The industrial camera 116 is designed to be tilted towards the unloading direction of the electric suction cups 114 and the external unloading box. The position sensor 115 monitors the alternating displacement of the two sets of electric suction cups 114 in real time, and the industrial camera 116 tracks and re-inspects the material adsorption and stacking of the two sets of electric suction cups 114 in real time to ensure the accuracy of material stacking.

[0054] The working principle of a hot-press material feeding device is as follows: First, the first electric push rod 72 is opened, driving the first main gear 73 to move outward and engage with the first auxiliary gear 74. Then, the double-head motor 71 is opened, and the first main gear 73 and the first auxiliary gear 74, which are in position, drive the horizontal shaft 75 to rotate. The horizontal shaft 75 drives the winding frames 76 at both ends to wind up the wire ropes. The two sets of winding frames 76 drive the two wire ropes 77 to wind up the wire ropes. As the length of the two wire ropes 77 gradually shortens, and with the main slide 13 and the auxiliary slide 14 sliding in the transverse groove 12, the two wire ropes 77, whose lengths are gradually shortening, pass through the main slide. 13 drives the material on the placement table 3 to be conveyed forward on the conveyor frame 1. At the same time, the main slide 13 drives the return springs 16 in the two sets of limit heads 15 to stretch forward. Meanwhile, the horizontal shaft 75 drives the two sets of ratchet 81 to rotate synchronously. With the two limit springs 83 providing elastic support and reset for the two pawls 82, the two sets of ratchet 81 force the two pawls 82 to jump on them, and drive the pusher head 84 to jump accordingly. The two sets of ratchet 81 on the horizontal shaft 75 play a back-slip restriction role on the two sets of winding frames 76 to prevent the placement table 3, which is conveying material forward, from sliding backward.

[0055] When the placement platform 3 passes the stop member 87, the stop groove 19 applies downward pressure to the stop member 87, forcing the stop member 87 to drive the rotating rod 85 to rotate. The rotating rod 85 drives the spring coil 86 to rotate and wind, and the rotating rod 85 also drives the diagonally designed stop head 18 to rotate, which stops the downward pressure on the stop member 87. After the placement platform 3 passes the stop member 87, the stop member 87, which loses downward pressure, is reset by the reset force of the spring coil 86 on the rotating rod 85. Similarly, the placement platform 3 for forward material conveying operation passes the stop member 87 in sequence, and several sets of stop members 87 also play an orderly reverse interception role for the placement platform 3 until the placement platform 3 reaches the unloading point of the conveyor frame 1. The last set of stop members 87 then stops the placement platform 3 after it has reached the unloading point, so that the placement platform 3 after it has reached the unloading point of the conveyor frame 1 is stably stopped, waiting for the unloading operation.

[0056] During the material conveying process of the placement platform 3 along with the conveyor frame 1, the two sets of main spur gears 92 inside the placement platform 3, driven by the meshing transmission of the teeth 91 inside the two sets of baffles 2, force the two sets of main spur gears 92 to rotate. The rotating main spur gears 92 drive the two sets of cleaning discs 94 to clean the area where the placement platform 3 passes through the conveyor frame 1. Simultaneously, the two sets of main spur gears 92 also drive the two sets of scraping strips 95 on the spur gears 93 to rotate, also wiping the area where the placement platform 3 passes through the conveyor frame 1, thus completing the process of the conveyor frame 1... The cleaning and wiping are carried out simultaneously. At the same time, the two sets of main sprockets 92 and the driven sprockets 93 drive the four sets of exhaust fans 96 to rotate in the air collection chamber 20 and generate air force. The air force is then blown evenly to the material area on the placement platform 3 through the four sets of flow equalization nets 97. This helps to dissipate heat from the hot-pressed material and also blows away and cleans the dust on the material. In addition, the air force in the air collection chamber 20 is blown evenly to the four corner areas of the material on the placement platform 3 through the ventilation holes 22 on the ventilation duct 21, which plays a role in helping to dissipate heat and blow away dust from the material.

[0057] After the material on the placement table 3 is conveyed to the unloading point of the conveyor frame 1, the dual-head motor 71 is first stopped, then the first electric push rod 72 is closed and the first main gear 73 is moved inward to disengage from the meshing part of the first auxiliary gear 74 to the initial position. Then, the second electric push rod 101 is opened and the second main gear 102 is moved outward to engage with the meshing part of the second auxiliary gear 103. Then, the dual-head motor 71 is reopened and the turntable 105 on the vertical shaft 104 is rotated through the meshing of the second main gear 102 and the second auxiliary gear 103. The turntable 105 drives the swing frame 106 to swing back and forth horizontally through the protrusion. The swing frame 106 drives the support arm 113 and the electric suction cup 114 on the three-stage electric cylinder 112 to swing back and forth through the sliding part 111.

[0058] Two sets of electric suction cups 114 on the swing arm 113 alternately swing along the placement platform 3. The height of the two sets of electric suction cups 114 is adjusted in three stages by the three-stage electric cylinder 112 through the swing arm 113. After the two sets of electric suction cups 114 adsorb the material on the placement platform 3 in an alternating swing manner, they are then alternately stacked in the two sets of external material boxes. During this period, the position sensor 115 monitors the material adsorption position between the two sets of electric suction cups 114 and the external material boxes in real time. The industrial camera 116 tracks and re-inspects the stacking of the material between the two sets of electric suction cups 114 and the external material boxes in an alternating swing state to ensure that the material is alternately stacked in the two sets of external material boxes. The inspection personnel use the pre-inspection platform 5 to randomly inspect the material in the two sets of external material boxes.

[0059] After all the materials on the placement platform 3 have been stacked and unloaded, first control the double-head motor 71 to shut down, then control the second electric push rod 101 to shut down and drive the second main gear 102 to move inward and disengage from the meshing part of the second auxiliary gear 103 to the initial position. Then manually turn the dial head 84 and drive the two pawls 82 to disengage from the ratchet 81. After releasing the reverse restriction measures of the ratchet 81 on the two winding frames 76 at both ends of the horizontal shaft 75, control the two sets of winding frames 76 to rotate in opposite directions and loosen the two steel wire ropes 77. The placement platform 3, which has lost its tension, moves back to its original position on the conveyor frame 1 under the rebound force of the two return springs 16. When the empty placement platform 3 passes the raised stop 87, the raised stop 87 can be pressed down in advance to allow the empty placement platform 3 to pass back to the loading position of the conveyor frame 1 and prepare for the feeding and conveying of the next batch of materials.

[0060] It should be noted that the specific models and specifications of the dual-head motor 71, electric push rod, and three-stage electric cylinder 112 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0061] The power supply circuits for the dual-head motor 71, the electric push rod, and the three-stage electric cylinder 112 are clear to those skilled in the art and will not be described in detail here.
