[0025] Ginseng Figures 1 to 5 As shown, a feeding mechanism for pulp molded products includes a conveying mechanism 1 connected between a molding machine and a placement rack, the conveying mechanism 1 is movably arranged between the molding machine and the placement rack through a mounting frame, the mounting frame includes a gantry 2, a lifting shaft 3 slidably connected to the gantry 2 and a connecting frame 4 arranged at the bottom end of the lifting shaft 3, and the conveying mechanism 1 is slidably arranged on the connecting frame 4.

[0026] In this technical solution, the molding machine and the placement rack are both existing structures, wherein the placement rack is a multi-layer structure, and a number of pulp molded products can be placed in each layer of the placement rack. After the molding machine completes the pressing of a single or multiple pulp molded products, the conveying mechanism moves to the side of the molding machine discharge, and the pulp molded products are transported to the conveying mechanism through the molding machine's conveyor belt and other output devices, and then the conveying mechanism moves to the placement layer corresponding to the placement rack, and transfers the pulp molded products to the corresponding placement layer. This action is repeated, and when the placement rack is full of pulp molded products, the fully loaded placement rack is moved to the drying or drying area, and the empty drying rack is placed in the docking area with the conveying mechanism. The whole process does not require manual participation, thereby improving production efficiency, while avoiding deformation and other damage caused by manual picking, and improving product qualification rate.

[0027] For example, see Figures 1 to 3 As shown, the conveying mechanism 1 includes a horizontally arranged support frame 11, rollers 12 rotatably arranged at both ends of the support frame 11, and a conveying belt 13 sleeved on the two rollers 12, and a first motor (not shown) is connected to the end of one roller 12.

[0028] In this technical solution, the support frame, rollers and conveyor belt are all conventional structures. The conveyor belt is arranged horizontally to prevent the pulp molded product from sliding on its surface. The first motor is fixed to the side of the support frame by conventional bolts or motor seats, and drives the corresponding rollers by conventional couplings or chains or synchronous belts or gears to achieve the rotation of the conveyor belt. The first motor is arranged at the end of the conveyor belt away from the placement rack to prevent the first motor from interfering with the placement rack when the conveyor belt enters the placement rack near the end of the placement rack.

[0029] For example, see Figures 1 to 3 As shown, the support frame 11 includes two parallel support rods and roller 12 mounting seats respectively arranged at both ends of the support rods, and the outer sides of the support rods are slidably connected to the connecting frame 4 through the first guide rails.

[0030] In this technical solution, in order to reduce the deadweight of the conveying mechanism, the support rod is made of conventional aluminum profiles with preset grooves on its surface. The first guide rail and the mounting seat are respectively installed on the support rod by conventional bolts and preset nuts. The two ends of the roller can also be directly connected to the support rod by conventional bearing seats. The connecting frame includes two oppositely arranged side panels and a top plate connected to the top ends of the two side panels. The sliders of the first guide rail are respectively fixed to the inner walls of the corresponding side panels by bolts, etc. The top end of the top plate is connected to the lifting shaft, and the bottom surface of the top plate and the conveyor belt are spaced apart to ensure that there is enough space to accommodate the pulp molded products.

[0031] For example, see Figures 1 to 3 As shown, a first rack 14 is disposed on the bottom surface of a support rod, and a second motor 15 is disposed in the connecting frame 4 and is connected to a first gear 16 meshed with the first rack 14 .

[0032] In this technical solution, the first rack is arranged on the bottom surface of the corresponding support rod by conventional bolts and prefabricated nuts, the second motor is a conventional servo motor, and is arranged on the outer wall of the corresponding side plate of the connecting frame (the side away from the conveyor belt) by conventional motor seats, etc., its output shaft passes through the corresponding side wall, and is connected with a first gear, the first gear is meshed with the first rack, so that the conveyor belt is driven to move as a whole by the second motor, before the molding machine discharges the material, the conveyor belt moves to the side of the output device such as the conveyor belt of the molding machine, when the molding machine discharges the material, the conveyor belt and the conveyor belt of the molding machine rotate synchronously, all the pulp molded products are moved from the conveyor belt to the conveyor belt, the conveyor belt stops rotating, the conveying mechanism moves to one side of an empty placement layer of the placement rack, the second motor starts, the conveyor belt moves to the top surface of the corresponding placement layer, the second motor reverses, and the first motor starts at the same time, driving the conveyor belt to rotate, while the conveyor belt moves as a whole to the side away from the placement rack, the pulp molded products fall from the surface of the conveyor belt to the top surface of the corresponding placement layer in sequence, completing the transfer of the pulp molded products.

[0033] Exemplarily, a plurality of water leakage holes (not shown) are provided in the conveyor belt 13 .

[0034] In this technical solution, the pressed pulp molded product contains a certain amount of moisture, which will remain on the surface of the conveyor belt and be easily absorbed by subsequent pulp molded products or cause the pulp molded products to slip on the conveyor belt surface and other adverse effects. The formed water droplets are guided to the ground through the provided leakage holes, or a sewage bucket is placed on the ground to collect and treat the dripping water droplets.

[0035] For example, see Figure 3 As shown, the conveyor belt 13 is provided with an inclined surface at one end close to the placement rack.

[0036] In this technical solution, a wedge block or a wedge-shaped sheet metal is provided inside the conveyor belt near the placement rack. The conveyor belt slides along the surface of the wedge block or the wedge-shaped sheet metal to reduce the height difference of the pulp molded product from falling from the conveyor belt surface to the placement rack, thereby avoiding its deformation or damage. The wedge block or the wedge-shaped sheet metal is a conventional structure, and mounting ears with strip-shaped structures protrude from both ends, and are fixed to the outer wall of the corresponding mounting seat by bolts.

[0037] For example, see Figure 1 and Figure 4 As shown, the gantry 2 includes a crossbeam and vertical beams supported at both ends of the crossbeam, and the lifting shaft 3 is slidably connected to the crossbeam through a slide seat 5.

[0038] In this technical solution, two vertical beams are vertically arranged on the ground by means of embedded bolts or chemical anchors to support the horizontally arranged cross beams, thereby forming a conventional gantry structure. The conveyor belt is suspended in the air in conjunction with the lifting shaft and the connecting frame, and the sliding seat and the lifting shaft are used to realize the lateral (in the direction of the length of the cross beam) and vertical (in the direction of the length of the lifting shaft) movement of the conveyor belt. It can simultaneously connect to multiple forming machines and multiple multi-layer placement racks, thereby improving the utilization rate of the feeding mechanism.

[0039] For example, see Figure 1 and Figure 4 As shown, a second rack 6 is disposed on the surface of the crossbeam, a third motor 7 is disposed in the slide 5, and is connected to a second gear (not shown) meshed with the second rack 6, and is slidably connected to the crossbeam via a second guide rail 8.

[0040] In this technical solution, the slide includes a horizontal plate and a vertical plate which are perpendicular to each other. The vertical plate is slidably connected to the side of the beam through a second guide rail. The horizontal plates are spaced above the top surface of the beam. The second rack is fixed to the top surface of the beam through conventional bolts, etc. The third motor is a conventional servo motor, etc., and is fixed to the top surface of the horizontal plate through conventional bolts and a motor seat, etc. Its output shaft passes through the horizontal plate and is connected to a second gear meshing with the second rack. The slide is driven to reciprocate along the beam by the third motor, that is, the conveyor belt is driven to move laterally, wherein the second rack and the second gear can also be replaced by a conventional screw rod and nut, the third motor is connected to one end of the screw rod, the slide is connected to the nut, or the third motor, the second rack and the second gear can be replaced by a conventional slide electric cylinder.

[0041] For example, see Figure 1 and Figure 4 As shown, a connecting seat 9 is provided on the side of the slide 5 close to the lifting shaft 3, and both sides of the lifting shaft 3 are slidably connected to the connecting seat 9 through third guide rails 10 respectively. A third rack 20 is provided on the side of the lifting shaft 3 close to the slide 5, and a fourth motor 30 is provided in the slide 5, and is connected to a third gear meshing with the third rack 20.

[0042] In this technical solution, the connecting seat includes two end plates perpendicular to the vertical plate of the slide seat, and are fixed to the corresponding side surfaces of the vertical plate by conventional bolts. The ends of the two end plates facing away from the vertical plate are connected by a connecting plate to ensure the fixing strength of the end plates. A space for accommodating a lifting shaft is formed in the connecting seat. The lifting shaft is made of conventional aluminum profiles, and third guide rails are respectively arranged on both sides close to the end plates. The sliders of the third guide rails are respectively fixed to the inner walls of the corresponding end plates (the side walls close to the lifting shaft) by bolts, etc. A third rack is arranged on one side of the lifting shaft close to the slide seat by conventional bolts and preset nuts, etc. An extension plate protrudes from the top end of one side of the vertical plate of the slide seat close to the third rack, and the fourth motor is a conventional servo motor The third rack and the third gear can also be replaced by conventional screw rods and nut, the fourth motor is connected to one end of the screw rod, and the lifting shaft is connected to the nut, or the connecting seat, the fourth motor, the third rack, the third gear and the lifting shaft can be replaced by conventional servo electric cylinders, the servo electric cylinders are directly fixed to the vertical plate of the slide seat, and the end of the piston rod is fixed to the top surface of the connecting frame by bolts.

[0043] For example, see Figure 1 and Figure 4 As shown, a fixing seat 40 connected to the lifting shaft 3 is provided at the top of the connecting frame 4 .

[0044] In this technical solution, baffles are respectively provided on both sides of the top surface of the connecting frame top plate to facilitate the rapid positioning and installation of the fixing seat. The fixing seat includes two L-shaped supports, which are respectively fixed to the top surface of the connecting frame top plate by bolts, etc. The bottom end of the lifting seat is arranged between the two L-shaped supports and is fixed by bolts and pre-set nuts.

[0045] See also Figure 5As shown, the feeding mechanism can serve multiple molding machines and multiple multi-layer placement racks at the same time. Take two molding machines (molding machine No. 1 and molding machine No. 2) and an eight-layer placement rack as an example (the bottom layer is the first placement layer). Each placement layer is divided into four placement areas, and each placement area can meet the placement needs of the molding machine for one discharge. Before the molding machine No. 1 discharges, the conveyor belt is driven by the third motor and the fourth motor to move to the side of the output device such as the conveyor belt of the molding machine No. 1, and is at the same horizontal height as the conveyor belt of the molding machine No. 1. When the molding machine No. 1 discharges, the first motor drives the conveyor belt and keeps synchronous rotation with the conveyor belt of the molding machine No. 1. All pulp molded products are moved from the conveyor belt of the molding machine No. 1 to the conveyor belt, and the conveyor belt stops rotating. The conveyor mechanism is driven by the third motor and the fourth motor to move to one side of the first placement layer of the placement rack (starting from the bottom layer of the placement rack to avoid top-heavy and loss of balance). The second motor is started, and the conveyor belt moves to the top surface of the first placement layer (within the same placement layer). , first placed in the placement area away from the molding machine side to avoid the pulp molded products placed in the subsequent placement, the second motor reverses, and the first motor starts, driving the conveyor belt to rotate. While the conveyor belt moves as a whole to the side away from the placement rack, the pulp molded products fall from the conveyor belt surface to the top surface of the corresponding placement layer in sequence, completing the transfer of the pulp molded products. During the continuous pressing of the No. 1 molding machine, the conveyor belt is driven by the third motor and the fourth motor to move to the side of the output device such as the conveyor belt close to the No. 2 molding machine, and completes the rotation of the pulp molded products of the No. 2 molding machine, that is, the feeding mechanism is alternately connected to the No. 1 molding machine and the No. 2 molding machine, reducing waiting time and improving utilization. After pulp molded products are placed on each layer of the placement rack, the fully loaded placement rack is moved to the drying or drying area, and the empty drying rack is placed in the docking area with the conveying mechanism. The whole process does not require manual participation, which improves production efficiency, while avoiding deformation and other damage caused by manual picking, and improving product qualification rate.

[0046] In summary, the feeding mechanism for pulp molded products has a simple structure, and the pulp molded products produced by the molding machine are automatically transferred to the placement rack, thereby improving production efficiency, while avoiding deformation and other damages caused by manual handling, thereby improving the product qualification rate.

[0047] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
