DETAILED DESCRIPTION

[0047] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0048] The embodiment of the present application provides a driving feeding device for plastic-wrapped wood extruded strip production, solves the problem of uneven manual feeding pressure and easy strip disconnection and finished product fracture in the prior art, and improves plastic-wrapped wood extruded strip production efficiency.

[0049] The technical scheme in the embodiment of the present application is to solve the above technical problem, and the general idea is as follows:

[0050] The plastic-wrapped wood extrusion process requires that the feeding of the extruded strip must be continuous. In the prior art, physical connection (nailing or gluing) is usually used, and then manual feeding is performed without interruption to the plastic-wrapped wood mold. However, the physical connection method has the following problems: nailing has serious nail marks that affect the feeding flow; gluing affects the mold flow channel, and the adhesion of the flow channel causes paste, and the manual feeding pressure is uneven, which easily causes strip disconnection and finished product fracture, resulting in low production efficiency.

[0051] It is found through research that, as shown in Figures 1-7 By setting up the active feeding device, the active feeding device is connected with the plastic-wood extrusion die, the active feeding device feeds the plastic-wood extrusion die, the active roller and the driven wheel on the active feeding device are used to tightly compact the extruded slats, and the active roller gives uninterrupted and stable forward thrust through the rubber sleeve, the extruded slats are fed into the die, and the friction between the active roller and the technical slats is used to facilitate the feeding operation of the active roller combined with the driven wheel on the technical slats;

[0052] In actual application, it is found that direct feeding with the active roller combined with subsequent automatic feeding of the material bin will cause slipping. After repeated research, a rubber sleeve is set on the surface of the active roller to increase the friction of the extruded slats during active feeding, thereby realizing automatic feeding and active feeding operation. The outer surface of the rubber sleeve is provided with a pattern to increase the roughness, and the feeding will be more stable.

[0053] Through the above research, the problem of uneven manual feeding pressure and easy disconnection of slats and breakage of finished products in the prior art is solved, and the production efficiency of plastic-wood extruded slats is improved.

[0054] In order to better understand the above technical solutions, the above technical solutions will be described in detail in combination with the drawings of the specification and specific embodiments.

[0055] Embodiment:

[0056] As shown in Figures 1-5 An active feeding device for plastic-wood extruded slat production, comprising a frame body 1 and a driving motor 12 installed on the frame body 1, a plurality of active rollers 122 are rotatably connected to the frame body 1, and a transmission wheel 123 is fixedly sleeved on one end of each active roller 122;

[0057] A plurality of transmission wheels 123 are synchronously transmitted through chains;

[0058] The output end of the driving motor 12 is drivingly connected with one of the transmission wheels 123 through a belt 121;

[0059] At least two limiting profiles 101 are installed on the frame body 1, and the spacing formed between the two limiting profiles 101 is used for limiting the extruded slats;

[0060] A plurality of driven wheels 51 are installed on the frame body 1, and each driven wheel 51 is located directly above the spacing formed between the corresponding limiting profiles 101;

[0061] A rubber sleeve 10 is fixedly sleeved on the active roller 122;

[0062] When feeding, the plurality of driven wheels 51 above the gap are in abutment with the extruded slats placed in the gap.

[0063] By setting the active feeding device, the active feeding device is connected with the plastic-wood extrusion die, the active feeding device feeds the plastic-wood extrusion die, the active roller 122 and the driven wheel 51 on the active feeding device are used to tightly compact the extruded slats, and the active roller 122 provides uninterrupted and stable forward thrust to the extruded slats, and the extruded slats are fed into the die, and the rubber sleeve 10 is used to lift the extruded slats. The friction between the active roller 122 and the technical plate facilitates the feeding operation of the active roller 122 combined with the driven wheel 51 on the technical slats, solves the problem of uneven pressure in manual feeding in the prior art, and the problem of slat disconnection and product fracture is solved. The production efficiency of the plastic-wood technical slats is improved.

[0064] As shown in Figures 1-2 The frame body 1 is provided with at least two mounting blocks 11, and an adjusting groove 111 is formed in each mounting block 11 for adjusting the fixed position of the limiting profile 101 to control the distance between adjacent mounting blocks 11.

[0065] The plurality of limiting profiles 101 are slid through the adjusting grooves 111 and fixed by bolts.

[0066] By providing the mounting blocks 11 on the frame body 1 and adjusting the fixed position of the limiting profile 101 through the adjusting grooves 111 on the mounting blocks 11, the distance is adjusted, and the feeding operation of the extruded slats of different widths is facilitated.

[0067] As shown in Figures 1-2 and Figures 5-6 A plurality of driven wheels 51 are mounted on the frame body 1 through at least two groups of first adjusting structures.

[0068] Each group of first adjusting structures is composed of two symmetrically arranged first adjusting assemblies 3 and a plurality of second adjusting assemblies 4 arranged between adjacent two groups of first adjusting assemblies 3.

[0069] The first adjusting assembly 3 comprises a first vertical rod 30 and a first adjusting block 31 sleeved along the vertical direction of the first vertical rod 30, the first adjusting block 31 slides along the vertical direction of the first vertical rod 30 and is fixed with the first vertical rod 30 by bolts, and is used for synchronously adjusting the height between the plurality of driven wheels 51 and the surface of the rubber sleeve 10.

[0070] A plurality of second adjusting assemblies 4 are respectively mounted through corresponding first horizontal rods 40 and adjacent two first adjusting assemblies 3 located on the same side of the frame body 1.

[0071] By setting the first adjusting assembly 3, the first adjusting assembly 3 is used to realize different adjustments of the distance between the multiple driven wheels 51 and the surface of the rubber sleeve 10, and to realize feeding of extruded plates of different thicknesses while improving the adjustment efficiency of the driven wheels 51.

[0072] As shown in Figures 1-2 and Figures 5-6 The second adjusting assembly 4 comprises a second horizontal rod 41 and two second adjusting blocks 42.

[0073] The second horizontal rod 41 is horizontally slid with the two second adjusting blocks 42 and the corresponding first horizontal rod 40, and is fixed by bolts, and is used to adjust the distance between the driven wheels 51 installed on the adjacent two groups of second adjusting assemblies 4.

[0074] By setting the second adjusting assembly 4 in the form of a second horizontal rod 41 and two second adjusting blocks 42, the second adjusting assembly 4 is controlled to slide horizontally along the first horizontal rod 40, and then the distance between the driven wheels 51 installed on the adjacent two groups of second adjusting assemblies 4 is adjusted to meet the needs of different use scenarios.

[0075] As shown in Figures 5-6 The second adjusting assembly 4 further comprises multiple third adjusting blocks 43.

[0076] Each third adjusting block 43 slides horizontally along the outer surface of the second horizontal rod 41 and is fixed by bolts, and is used to adjust the distance between the adjacent two driven wheels 51 installed on the same second horizontal rod 41.

[0077] By setting the third adjusting block 43, the third adjusting block 43 is used to adjust the distance between the adjacent two driven wheels 51 installed on the same second horizontal rod 41, so as to facilitate the adjustment of the driven wheels 51 to the corresponding center position of the extruded plate, and improve the stability during the feeding of the extruded plate.

[0078] As shown in Figures 5-6 Each driven wheel 51 is fixed with the corresponding third adjusting block 43 through a fourth adjusting block 5.

[0079] The driven wheel 51 slides vertically along the fourth adjusting block 5 through the corresponding second vertical rod 50 and is fixed by bolts, and is used to adjust the distance between the single driven wheel 51 and the rubber sleeve 10.

[0080] By setting the driven wheel 51 to slide vertically along the fourth adjusting block 5 through the corresponding second vertical rod 50 and be fixed by bolts, the distance between the single driven wheel 51 and the rubber sleeve 10 is adjusted, and then different thicknesses of extruded plates can be fed synchronously.

[0081] As shown in Figure 1 andFigure 7 As shown, at least one hopper 2 matched with the extruded plate to be fed is installed on the frame body 1;

[0082] The position of the hopper 2 is matched with the corresponding adjacent two limiting profiles 101;

[0083] A plurality of extruded plates are vertically stacked in each hopper 2;

[0084] The friction between the rubber sleeve 10 and the extruded plate is greater than the friction between the extruded plates.

[0085] By setting the hopper 2, the automatic feeding of the feeding device is realized by gravity, and the friction between the rubber sleeve 10 and the extruded plate is greater than the friction between the extruded plates. The rubber sleeve 10 generates a pushing force on the extruded plate located on the rubber sleeve 10 through the rotation of the driving roller 122 and the pressing force of the driven wheel 51, realizing the active feeding operation of the extruded plate.

[0086] It should be noted that the friction coefficient between the extruded plates is 0.2-0.3, and the friction coefficient between the extruded plate and the rubber is 0.4-0.6.

[0087] And according to the actual demand, the surface of the rubber sleeve 10 is provided with a protrusion or a rough texture, which is used to improve the roughness of the rubber sleeve 10, thereby improving the friction between the rubber sleeve 10 and the extruded plate, and facilitating the feeding of the extruded plate by the rubber sleeve 10.

[0088] As shown in Figure 1 and Figure 7 A plurality of hoppers 2 are installed on the frame body 1 through the second adjusting structure.

[0089] The second adjusting structure is the same as the first adjusting structure.

[0090] Each hopper 2 is detachably connected to the third adjusting block 43 through the connecting piece 6, and is fixed by a bolt.

[0091] Similarly, by setting the hopper 2 to be installed on the frame body 1 by the second adjusting structure, the adjustment of the hopper 2 in three dimensions is realized, thereby facilitating the automatic feeding operation of the hopper 2 to meet the application requirements of different types of extruded plates and different scenes.

[0092] When working, first, according to the width of the extruded plate to be fed, the limiting profile 101 is adjusted, and the distance between the adjacent two limiting profiles 101 is adjusted to meet the passing of the extruded plate. During adjustment, the limiting profile 101 is controlled to slide along the adjusting groove 111, and after adjustment is completed, the limiting profile 101 and the mounting block 11 are fixed by a bolt to complete the adjustment of the distance between the limiting profiles 101;

[0093] According to the thickness of the feeding extruded plate required by the corresponding limiting profile 101, the vertical distance between the driven wheel 51 and the rubber sleeve 10 is adjusted to meet the pressure connection of the extruded plate by the driven wheel 51, when the multiple driven wheels 51 are synchronously adjusted, only the height of the multiple first adjusting blocks 31 and the corresponding first vertical rod 30 needs to be adjusted, when the single driven wheel 51 needs to be adjusted, the second vertical rod 50 is controlled to slide along the vertical direction of the fourth adjusting block 5, and then fixed by the bolt, so as to realize the adjustment of the vertical height of the single driven wheel 51, so as to meet the pressure connection of the corresponding extruded plate by the driven wheel 51 in different scenes;

[0094] Then, the corresponding material bin 2 of the extruded plate is selected, and the material bin 2 is installed to the second adjusting structure through the connecting piece 6, and the three-dimensional adjustment of the material bin 2 is realized through the second adjusting structure, so as to match the foregoing adjusted driving feeding device;

[0095] After the adjustment is completed, the multiple extruded plates are stacked along the inner wall of the material bin 2, at this time, the lowermost extruded plate is in contact with the surface of the rubber sleeve 10;

[0096] Finally, the driving motor 12 is started to provide the driving force for the feeding device, since the output end of the driving motor 12 is connected with one of the driving rollers 122 through the belt 121, and the multiple driving rollers 122 are synchronously driven by the chain, the driving of the driving motor 12 controls the synchronous rotation of the multiple rubber sleeves 10, when the rubber sleeve 10 rotates synchronously with the driving roller 122, the lowermost extruded plate moves forward under the action of the friction force, and then slides along the gap formed between the corresponding limiting profiles 101, in the process of sliding, the driven wheel 51 between the corresponding limiting profiles 101 pressure-connects the extruded plate in the process of the driving feeding, so as to ensure the stability in the whole process of the driving feeding;

[0097] In this process, after the lowermost extruded plate completely separates from the material bin 2, the extruded plate in the material bin 2 falls to the outer surface of the rubber sleeve 10 under the action of the gravity, so as to realize the automatic discharging.

[0098] It should be noted that the spacing between the lowermost part of the material bin 2 and the rubber sleeve 10 is adjusted, and only one extruded plate is discharged at a time;

[0099] And the multiple driving rollers 122 are used for feeding, and there is a gap between the adjacent two driving rollers 122, which can facilitate the falling of the wood chips attached to the extruded plate during the machining;

[0100] The side of the whole device away from the material bin 2 is connected with the feeding end of the plastic-wrapped wood mold, and is used for the feeding operation of the feeding end of the plastic-wrapped wood mold.

[0102] 1. By setting the active feeding device, the active feeding device is connected with the plastic-wood extrusion die, the active feeding device feeds the plastic-wood extrusion die, the active roller 122 and the driven wheel 51 on the active feeding device are used to tightly compact the extruded slats, and the active roller 122 provides uninterrupted and stable forward thrust to the extruded slats, and the extruded slats are fed into the die, and the rubber sleeve 10 is used to lift the extruded slats, the friction between the active roller 122 and the technical slats facilitates the feeding operation of the active roller 122 in combination with the driven wheel 51 on the technical slats, the problems of uneven manual feeding pressure and easy disconnection of the slats in the prior art are solved, and the production efficiency of the plastic-wood technical slats is improved.

[0103] 2. By setting the hopper 2, the automatic feeding of the feeding device is realized by gravity, the friction between the rubber sleeve 10 and the extruded slats is greater than the friction between the extruded slats, the rubber sleeve 10 generates a pushing force on the extruded slats located on the rubber sleeve 10 through the rotation of the active roller 122 and the pressing force of the driven wheel 51, and the active feeding operation of the extruded slats is realized.

[0104] 3. The hopper 2 is installed on the frame 1 by using the second adjusting structure, so as to realize the adjustment of the hopper 2 in three dimensions, and the automatic feeding operation of the hopper 2 is facilitated to meet the application requirements of different types of extruded slats and different scenes.
