Description

Technical Field

[0001] The invention relates to the technical field of extrusion equipment, in particular to a direct-effect floor substrate extruder. Background Art

[0002] In recent years, with the development of the global building decoration industry and the growing demand of consumers for environmentally friendly, durable and beautiful floor materials, the flooring market has shown a trend of diversification and personalization. SPC flooring has become a popular choice in the market due to its excellent physical properties, such as waterproof, anti-slip, wear-resistant, easy to maintain, and diversified surface design. Especially in commercial spaces, public places and residential decoration, SPC flooring is increasingly widely used.

[0003] As the core equipment of SPC floor substrate production line, the technical level of extruder directly affects the quality, production efficiency and energy consumption of products. At present, the common extruders on the market are mainly screw extruders, which are divided into single-screw extruders and twin-screw extruders according to the number of screws. The screw extruder mainly pressurizes and pushes the fluid raw materials through the rotating screw inside, so that the raw materials are discharged through the mold at the discharge end of the extruder to complete the shaping of the raw materials. However, due to the fluidity of the raw materials, the force of the screw on the raw materials can only be achieved through the spiral surface of the screw. Therefore, the raw materials are easy to flow on the screw, resulting in a decrease in the effectiveness of the driving force provided by the screw for the raw materials. Part of the energy is consumed in the form of frictional heat energy, resulting in a large energy loss. Especially when it is necessary to provide a large driving force for the raw materials, the effectiveness of its force transmission is even lower. Summary of the invention

DETAILED DESCRIPTION

[0019] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] like Figures 1 to 4 As shown, a direct-effect floor substrate extruder of the present invention comprises: A pushing unit 100, used for pushing the raw materials; A feeding pipe 200 is connected and installed on the pushing unit 100; The pressure-homogenizing auxiliary structure 300 is connected and installed on the pushing unit 100, and is used for performing pressure stabilization processing on the raw material extruded by the pushing unit 100; A discharge pipe 400 is connected and installed on the pressure equalization auxiliary structure 300; The push unit 100 includes: The outer ring 101 has an annular material groove on its inner wall; The inner ring 102 is rotatably mounted on the inner side of the outer ring 101, and the inner ring 102 blocks the material trough to form a ring-shaped closed state. A plurality of partitions 105 are slidably inserted on the inner ring 102. The partitions 105 are elastically slidably arranged along the radial direction of the inner ring 102. The elasticity is used to maintain the sealing fit between the end of the partition 105 and the outer ring 101. The partitions 105 separate the internal space of the material trough; A filling block 103 is fixedly installed in the material trough. The filling block 103 is used to separate the material trough. Two channels 104 are opened on the filling block 103. One channel 104 is connected to the feed pipe 200, and the other channel 104 is connected to the pressure-equalizing auxiliary structure 300. The side wall of the filling block 103 extends along the axial direction of the outer ring 101, and the two ends are respectively connected to the side wall of the outer ring 101 to divide the annular material groove into two areas. When the partition 105 passes through the side wall, it is squeezed by the side wall and elastically retracts. The volume formed between the retracted partition and the adjacent rear partition changes with the rotation of the inner ring 102. Since the filling block 103 divides the material trough, that is, the middle part of the side wall of the filling block 103 is in sliding contact with the outer wall of the inner ring 102, the side wall of the filling block 103 can be divided into two front and rear guide surfaces, and the two channels 104 are respectively located on the two guide surfaces. In addition, by utilizing the characteristics of the installation position of the filling block 103, when the outer end of the partition 105 slides onto the guide surface, the guide surface will guide the partition 105 so that it can slide on the inner ring 102; the axes of the outer ring 101 and the inner ring 102 are both vertical and overlap each other, and the outer ring 101 and the inner ring 102 together form an annular closed material trough space, which is used to transport raw materials. The raw materials here can be materials recycled from plastic waste or directly purchased raw materials; the position of the outer ring 101 is fixed, and the inner ring 102 can rotate on the outer ring 101. At this time, the inner ring 102 will drive multiple partitions 105 to rotate synchronously. The space between two adjacent partitions 105 is used to hold the raw materials. When the partition 105 passes through the middle of the side wall of the filling block 103 and moves away from the side of the filling block 103 on a guide surface of the filling block 103, When sliding in the middle direction of the wall, the partition 105 slides and inserts into the material trough. At this time, the space between the partition 105 and the filling block 103 will gradually increase, and the raw material can be introduced into the space through the feeding pipe 200, thereby realizing the feeding of the raw material. When two adjacent partitions 105 leave the filling block 103 and move in the material trough, the size of the space between the two adjacent partitions 105 remains unchanged. At this time, the raw material is in a conveying state, and because the raw material is directly pushed by the partition 105, the force can be directly transmitted to the raw material, which improves the force. The effectiveness of the transmission is achieved by realizing a direct-effect pushing method. When two adjacent partitions 105 move to another guide surface of the filling block 103 and move toward the middle of the side wall of the filling block 103, the guide surface can push the partition 105 to slide toward the middle of the inner ring 102, and the space between the two adjacent partitions 105 is reduced. The raw materials in the space can be discharged into the uniform pressure auxiliary structure 300 through the corresponding channel 104, thus completing the extrusion of the raw materials. By utilizing the continuous rotation of the inner ring 102, continuous and direct-effect extrusion of the raw materials can be achieved. In actual use, in order to melt the raw material and keep it in a fluid state, an electric heating structure may be installed on the outer ring 101 to heat the raw material.

[0021] When the partition 105 rotates with the inner ring 102, the partition 105 needs to slide on the inner ring 102, and this sliding is only provided by the side wall of the filling block 103, so its stability and sealing performance are obviously low. To improve this situation, it is necessary to adopt Figures 4 to 5In the structural manner shown, the pushing unit 100 further includes two discs 106, both of which are located inside the inner ring 102, and the two discs 106 are distributed up and down, and the two discs 106 are connected by a connecting plate 107, and guide grooves are provided on the end faces of the discs 106, and the two guide grooves are opposite to each other, and the guide grooves are composed of an arc groove 108 and a V-shaped groove 109, and the opening of the V-shaped groove 109 faces the direction away from the arc groove 108; A plurality of slide posts 110 are slidably arranged in the guide groove, and the slide posts 110 are connected to the partition 105. When the slide posts 110 slide in the arc groove 108, the partition 105 separates the material groove, and when the slide posts 110 slide in the V-shaped groove 109, the partition 105 slides on the inner ring 102; The two discs 106 are respectively located on the upper and lower sides of the partition 105. The upper and lower surfaces of the partition 105 on the inner side of the inner ring 102 are equipped with sliding columns 110. The sliding columns 110 are slidably installed in the guide groove, so that the two discs 106 can realize double guiding work of the partition 105. The center of the arc groove 108 coincides with the axis of the inner ring 102. Therefore, when the sliding column 110 slides in the arc groove 108, the partition 105 and the inner ring 102 are relatively stationary; the V-shaped groove 109 is composed of two arc-shaped parts, so that when one end of the partition 105 moves in a straight line along the guide surface of the filling block 103, the other end of the partition 105 can move along the arc-shaped part of the V-shaped groove 109, thereby ensuring that the partition 105 can move smoothly on the inner ring 102 to avoid jamming. The setting of the disc 106 and the guide groove thereon can make the movement of the partition 105 more stable and improve the sealing of the partition 105 when separating the material trough.

[0022] like Figure 2 As shown, the push unit 100 also includes: A support frame 111 is fixed on the outer ring 101, and a disc 106 is fixed on the support frame 111; A first motor 112 is fixed on the support frame 111; A first transmission wheel 113 is mounted on the output end of the first motor 112; A transmission ring 114 is mounted on the inner ring 102 and is in transmission connection with the first transmission wheel 113; The support frame 111 can be used to support the first motor 112, the first transmission wheel 113 and the two discs 106. The first motor 112 can drive the transmission ring 114 to rotate through the first transmission wheel 113, thereby driving the inner ring 102 to rotate, thereby realizing the equipment's conveying and extruding of raw materials.

[0023] like Figure 6 to Figure 7 As shown, the pressure equalization auxiliary structure 300 includes: A fixed cylinder 301 is mounted on the side wall of the outer ring 101 and communicated with a channel 104; The piston 302 is slidably disposed in the fixed cylinder 301; The sleeve 303 is mounted on the piston 302. The discharge pipe 400 passes through the piston 302 and the sleeve 303 and communicates with the interior of the fixed cylinder 301. The discharge pipe 400 is fixedly connected to the fixed cylinder 301. A counterweight unit connected to the casing 303 and used to provide a constant thrust for the casing 303; The discharge pipe 400 and the fixed cylinder 301 can be fixedly connected by a connecting frame, and the position of the discharge pipe 400 is fixed. The raw material can enter the fixed cylinder 301 through the extrusion of the pushing unit 100, and the raw material in the fixed cylinder 301 can be extruded into the mold through the discharge pipe 400, thereby completing the extrusion of the raw material; when the raw material enters the fixed cylinder 301, due to the pushing effect of the pushing unit 100 and the caliber limitation of the discharge pipe 400, there will be a pressure inside the raw material, and the pressure acts on the piston 302, so that the piston 302 can be pressed in the fixed cylinder 301. Sliding, at this time, the space inside the fixed cylinder 301 for storing raw materials increases. Since the counterweight unit can provide a constant thrust to the piston 302 through the sleeve 303, the raw material pressure inside the fixed cylinder 301 can be kept constant. When the raw material pressure increases or decreases, the pressure will cause the piston 302 to slide in the fixed cylinder 301, thereby automatically adjusting the space inside the fixed cylinder 301 for storing raw materials, so that the raw material pressure remains constant. In this way, the extruded raw material can have a constant pressure, avoiding pressure fluctuations that cause changes in raw material thickness and affect the floor processing quality.

[0024] like Figures 7 and 8 As shown, the counterweight unit includes: A first rack 304 is slidably mounted on the outer wall of the fixed cylinder 301 along the axial direction of the fixed cylinder 301, and the first rack 304 is connected to the sleeve 303; The tooth column 305 is rotatably mounted on the outer wall of the fixed cylinder 301, and the tooth column 305 is meshedly connected with the first rack 304; The second rack 306 moves vertically and is meshed with the gear column 305. A counterweight is disposed on the top of the second rack 306; The side plate 307 is fixed on the outer ring 101, and the second rack 306 is vertically slidably mounted on the side plate 307; The side plate 307 provides guidance and support for the second rack 306. The counterweight and the second rack 306 provide a lateral thrust for the first rack 304 through the tooth column 305 due to gravity. The first rack 304 provides a lateral thrust for the piston 302 through the sleeve 303, so that the piston 302 can provide a constant pressure for the raw material in the fixed cylinder 301. By utilizing the effect of gravity, the thrust of the piston 302 on the raw material can be kept constant, thereby improving the stability of the thrust.

[0025] When the piston 302 needs to provide different thrusts to the raw material, this can be achieved by changing the force of the counterweight on the second rack 306. Figure 8 As shown, the weight includes: A vertical slot plate 308 is vertically fixed on the outer wall of the outer ring 101; The counterweight block 309 is vertically slidably mounted on the vertical slot plate 308, and there is friction between the counterweight block 309 and the vertical slot plate 308; The telescopic rod 310 is used to connect the second rack 306 and the counterweight 309. The telescopic rod 310 is inclined, and the fixed end and the movable end of the telescopic rod 310 are locked by a top screw. The fixed end of the telescopic rod 310 is rotatably mounted on the second rack 306, and the movable end of the telescopic rod 310 is rotatably mounted on the side wall of the counterweight block 309. When the telescopic rod 310 is locked in length by the top screw on it, due to the inclination of the telescopic rod 310, the telescopic rod 310 uses its own gravity to generate a lateral thrust on the counterweight block 309. Since there is a friction force between the counterweight block 309 and the vertical slot plate 308, the friction force will share part of the vertical force of the counterweight block 309 and the telescopic rod 310, and the remaining force will directly act on the second rack 306, thereby providing counterweight for the second rack 306; when it is necessary to adjust the mating, the top screw on the telescopic rod 310 can be loosened, and the length of the telescopic rod 310 can be adjusted, so that the inclination angle of the telescopic rod 310 can be adjusted, so that the friction force between the counterweight block 309 and the vertical slot plate 308 changes, and the counterweight force acting on the second rack 306 is indirectly adjusted; It should be pointed out here that the structure realizes the adjustment of the counterweight by utilizing gravity and adjusting the shared gravity, without the need to adjust the counterweight by replacing the counterweight, and it can achieve a stepless adjustment effect and improve the adjustment accuracy.

[0026] like Figure 8As shown, a slide plate 311 is slidably provided on the vertical slot plate 308, and the slide plate 311 is connected to the counterweight block 309 by a spring clip 312. The spring clip 312 provides a basic thrust for the counterweight block 309, thereby generating a basic friction force between the vertical slot plate 308 and the counterweight block 309; since the friction force between the vertical slot plate 308 and the counterweight block 309 is adjustable, the counterweight block 309 can move laterally in a small range on the vertical slot plate 308, so the vertical slot plate 308 and the counterweight block 309 need to be relatively independent, and this independence will cause the counterweight block 309 to detach from the vertical slot plate 308. To avoid this phenomenon, the slide plate 311 and the spring clip 312 need to be used to limit the counterweight block 309 so that the counterweight block 309 remains on the vertical slot plate 308. When the counterweight block 309 moves, it will drive the slide plate 311 and the spring clip 312 to move.

[0027] In the initial state, since there is no raw material in the fixed cylinder 301, gravity will cause the piston 302 to move to a position close to the outer ring 101. When the raw material enters the fixed cylinder 301, if the raw material pressure is small, it cannot push the piston 302 to move and directly enters the discharge pipe 400. In this case, the raw material pressure cannot meet the production requirements. To avoid this phenomenon, the following method can be used: Figure 7 and Figure 8 In the structure shown, the end of the discharge pipe 400 facing the outer ring 101 is sealed, and a plurality of guide holes 401 are provided on the outer wall of the discharge pipe 400. A spring 313 for caching the second rack 306 is provided on the side plate 307. To cooperate with the spring 313, the second rack 306 can be set to a right angle shape, and the top of the second rack 306 is horizontal. In the natural state, the inner wall of the sleeve 303 seals the guide hole 401. At this time, the raw material in the fixed cylinder 301 cannot enter the discharge pipe 400. When the raw material enters the fixed cylinder 301, the raw material will push the piston 302 to move. When the second rack 306 rises, when the piston 302 and the sleeve 303 move and make the guide hole 401 appear in the fixed cylinder 301, the raw material in the fixed cylinder 301 can enter the discharge pipe 400 through the guide hole 401, and the raw material starts to be extruded normally, and the raw material pressure remains constant; through this structural method, it can be ensured that the pressure of the extruded raw material is always the specified requirement, and the raw material extrusion work can only be started when the second rack 306 and the counterweight thereon reach a certain height; the spring 313 on the side plate 307 can provide a buffering effect for the second rack 306.

[0028] During the transportation of the raw materials in the fixed cylinder 301, in order to make the raw materials near the inner wall of the fixed cylinder 301 and the raw materials in the middle of the fixed cylinder 301 form a cross flow to improve the uniformity of the raw materials, the following method can be used: Fig. 9As shown, the pressure-equalizing auxiliary structure 300 also includes a plurality of rotating columns 314, which are distributed in a ring shape around the axis of the fixed cylinder 301 in the fixed cylinder 301, and spiral blades 315 are arranged on the outer wall of the rotating column 314. The end of the rotating column 314 passes through the piston 302 and extends out, and the rotating column 314 is rotatably connected to the piston 302. When the rotating column 314 rotates, it stirs the raw materials in the fixed cylinder 301 through the spiral blades 315. Since the plurality of spiral blades 315 are distributed in a ring shape around the axis of the fixed cylinder 301, one side of the spiral blade 315 is close to the inner wall of the fixed cylinder 301, and the other side is close to the middle of the fixed cylinder 301. In this way, the spiral blade 315 can alternately transport and stir the raw materials near the inner wall of the fixed cylinder 301 and in the middle of the fixed cylinder 301, thereby ensuring that the raw materials in the fixed cylinder 301 are uniform as a whole.

[0029] like Figure 7 As shown, the pressure equalization auxiliary structure 300 also includes: A plurality of prisms 316 are located outside the fixed cylinder 301 and are slidably inserted into the plurality of rotating cylinders 314 respectively; A plurality of second transmission wheels 317 are respectively mounted on the plurality of prisms 316, and an annular tooth groove is formed on the outer circumferential wall of the second transmission wheel 317; A power unit, used to provide power for the sleeve 303 to rotate; The first rack 304 is rotatably connected with the sleeve 303, and an outer edge 318 is provided at the end of the fixed cylinder 301 away from the outer ring 101, and teeth are provided on the outer edge 318. The teeth on the outer edge 318 are meshed and connected with the teeth on the second transmission wheel 317, and the inner wall of the tooth groove on the second transmission wheel 317 will limit the outer edge 318, so that the position of the second transmission wheel 317 is limited by the fixed cylinder 301, so that the tooth groove on the second transmission wheel 317 and the teeth on the outer edge 318 are always in meshing state. When rotating, it will drive the piston 302 and multiple rotating columns 314 thereon to rotate synchronously. The rotating column 314 drives the second transmission wheel 317 to roll on the outer edge 318, so that the rotating column 314 and the spiral blade 315 can perform circular motion and self-rotation motion around the axis of the fixed cylinder 301. The spiral blade 315 can stir the raw materials in the fixed cylinder 301, and when the piston 302 moves laterally, the rotating column 314 and the prism 316 slide relative to each other, and by utilizing the shape characteristics of the prism 316, the rotating column 314 and the prism 316 can always maintain a transmission state.

[0030] like Figure 7 As shown, the power unit includes: A second motor 319 is fixed on the fixed cylinder 301; Two third transmission wheels 320, one of which is mounted on the output end of the second motor 319, and the other of which is slidably mounted on the sleeve 303 along the axis direction of the sleeve 303, and the sleeve 303 and the third transmission wheel 320 thereon rotate synchronously; A transmission belt 321 is sleeved on the two third transmission wheels 320 and is used to transmit power to the two third transmission wheels 320; When the second motor 319 is running, it will drive the third transmission wheel 320 and the transmission belt 321 to transmit, thereby driving the sleeve 303 to rotate. When the piston 302 and the sleeve 303 move laterally, the sleeve 303 and the third transmission wheel 320 thereon slide relative to each other and keep rotating synchronously. Of course, in order to prevent the transmission belt 321 from disengaging from the third transmission wheel 320, two ribs can be set on each third transmission wheel 320 to improve the stability of the transmission.

[0031] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
