Description

Technical Field

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

[0002] In recent years, with the development of the global building decoration industry and the increasing demand of consumers for environmentally friendly, durable and beautiful floor materials, the floor market has shown a trend of diversification and personalization. Due to its excellent physical properties, such as waterproof, anti-slip, wear-resistant, easy to maintain and other characteristics, as well as diverse surface designs, SPC floors have become a popular choice in the market. Especially in commercial spaces, public places and residential renovations, the application of SPC floors is becoming more and more extensive.

[0003] As the core equipment of the SPC floor substrate production line, the technical level of the extruder directly affects the product quality, production efficiency and energy consumption. At present, the common extruders in 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 internally rotating screw, so that the raw materials are formed and discharged through the die 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 realized 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, and part of the energy is consumed in the form of frictional heat energy, with relatively large energy losses. Especially when a large driving force needs to be provided for the raw materials, the effectiveness of the force transmission is even lower. Summary of the Invention

[0064] The following combines the drawings and embodiments to further describe in detail the specific implementation manners of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0065] As Figures 1 to 4 shown, a direct-effect floor substrate extruder of the present invention includes:

[0066] A pushing unit 100 for pushing raw materials;

[0067] A feed pipe 200, which is connected and installed on the pushing unit 100;

[0068] A pressure equalizing auxiliary structure 300, which is connected and installed on the pushing unit 100 and is used for performing a pressure stabilizing treatment on the raw materials extruded by the pushing unit 100;

[0069] A discharge pipe 400, which is connected and installed on the pressure equalizing auxiliary structure 300;

[0070] Among them, the pushing unit 100 includes:

[0071] The outer ring 101 has an annular material groove opened on the inner wall of the circumference;

[0072] The inner ring 102 is rotatably installed inside the outer ring 101, and the inner ring 102 seals the material groove to form an annular closed state. A plurality of partition plates 105 are slidably inserted through the inner ring 102. The partition plates 105 are elastically slidably arranged along the radial direction of the inner ring 102. The elasticity is used to keep the end of the partition plate 105 in sealing fit with the outer ring 101. The partition plates 105 divide the internal space of the material groove;

[0073] The filling block 103 is fixedly installed in the material groove. The filling block 103 is used to divide the material groove. Two channels 104 are opened on the filling block 103. One channel 104 is communicated with the feed pipe 200, and the other channel 104 is communicated with the pressure equalizing auxiliary structure 300;

[0074] The side wall of the filling block 103 extends along the axis direction of the outer ring 101, and the two ends are respectively connected with the side wall of the outer ring 101 to divide the annular material groove into two regions. When the partition plate 105 passes through the side wall, it is elastically retracted by the side wall extrusion. A space with a volume changing with the rotation of the inner ring 102 is formed between the retracted partition plate and its adjacent rear partition plate;

[0075] 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 guiding surfaces at the front and back. The two channels 104 are respectively located on the two guiding surfaces. And by using the characteristics of the installation position of the filling block 103, when the outer end of the partition 105 slides to the guiding surface, the guiding 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 coincide with each other. The outer ring 101 and the inner ring 102 together form an annular closed material trough space, which is used to transport raw materials. Here, the raw materials 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 raw materials. When the partition 105 passes through the middle part of the side wall of the filling block 103 and slides on one guiding surface of the filling block 103 in a direction away from the middle part of the side wall of the filling block 103, the partition 105 slides into the material trough. At this time, the space between the partition 105 and the filling block 103 will gradually increase, and the raw materials can be introduced into this space through the feed pipe 200, thus realizing the feeding work of the raw materials. When two adjacent partitions 105 both leave the filling block 103 and move in the material trough, the size of the space between two adjacent partitions 105 remains unchanged. At this time, the raw materials are in the conveying state. And because the raw materials are directly pushed by the partition 105, the acting force can be directly transmitted to the raw materials, improving the effectiveness of the acting force transmission and realizing the direct-acting pushing method. When two adjacent partitions 105 move to the other guiding surface of the filling block 103 and move towards the middle part of the side wall of the filling block 103, this guiding surface can push the partition 105 to slide towards the middle part of the inner ring 102. The space between two adjacent partitions 105 decreases, and the raw materials in this space can be discharged into the pressure equalizing auxiliary structure 300 through the corresponding channel 104, thus completing the extrusion work of the raw materials. By continuously rotating the inner ring 102, continuous and direct-acting extrusion work of the raw materials can be realized;

[0076] During actual use, in order to melt the raw materials and keep them in a flowing state, an electric heating structure can be installed on the outer ring 101 to heat the raw materials.

[0077] During the process of the partition 105 rotating with the inner ring 102, since 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, its stability and sealing performance are significantly low. To improve this situation, it is necessary to adopt such as Figures 4 to 5In the shown structural manner, the pushing unit 100 further includes two discs 106. Both of the two discs 106 are located inside the inner ring 102, and the two discs 106 are distributed vertically. The two discs 106 are connected by a connecting plate 107. Guide grooves are formed on the end faces of the discs 106. The directions of the two guide grooves are opposite to each other. The guide groove is composed of an arc groove 108 and a V-shaped groove 109. The opening of the V-shaped groove 109 faces away from the arc groove 108.

[0078] A plurality of sliding columns 110 are slidably arranged in the guide grooves. The sliding columns 110 are connected to the partition plate 105. When the sliding columns 110 slide in the arc groove 108, the partition plate 105 divides the material groove. When the sliding columns 110 slide in the V-shaped groove 109, the partition plate 105 slides on the inner ring 102.

[0079] The two discs 106 are respectively located on the upper and lower sides of the partition plate 105. The upper and lower surfaces of the partition plate 105 inside the inner ring 102 are both provided with sliding columns 110. The sliding columns 110 are slidably installed in the guide grooves. In this way, the two discs 106 can be used to realize the dual guiding work of the partition plate 105. The center of the arc groove 108 coincides with the axis of the inner ring 102. Therefore, when the sliding columns 110 slide in the arc groove 108, the partition plate 105 is relatively stationary with respect to the inner ring 102. The V-shaped groove 109 is composed of two arc parts. In this way, when one end of the partition plate 105 moves linearly along the guiding surface of the filling block 103, the other end of the partition plate 105 can move along the arc part of the V-shaped groove 109, so as to ensure that the partition plate 105 can move smoothly on the inner ring 102 and avoid jamming. By using the discs 106 and the guide grooves arranged thereon, the movement of the partition plate 105 can be made more stable, and the sealing performance of the partition plate 105 when dividing the material groove can be improved.

[0080] As Figure 2 shown, the pushing unit 100 further includes:

[0081] A support frame 111, fixed on the outer ring 101, and one disc 106 is fixed on the support frame 111;

[0082] A first motor 112, fixed on the support frame 111;

[0083] A first transmission wheel 113, installed on the output end of the first motor 112;

[0084] A transmission ring 114, installed on the inner ring 102, and the transmission ring 114 is in transmission connection with the first transmission wheel 113;

[0085] The support frame 111 can 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, so as to drive the inner ring 102 to rotate and realize the conveying and extrusion work of the equipment for the raw materials.

[0086] As shown Figures 6 to 7 in the figure, the pressure equalizing auxiliary structure 300 includes:

[0087] A fixed cylinder 301, which is installed on the side wall of the outer ring 101 and communicates with a channel 104;

[0088] A piston 302, which is slidably located inside the fixed cylinder 301;

[0089] A sleeve 303, which is installed on the piston 302. The discharge pipe 400 passes through the piston 302 and the sleeve 303 and communicates with the inside of the fixed cylinder 301. The discharge pipe 400 is fixedly connected to the fixed cylinder 301;

[0090] A counterweight unit, which is connected to the sleeve 303 and is used to provide a constant thrust for the sleeve 303;

[0091] The discharge pipe 400 and the fixed cylinder 301 can be fixedly connected through a connecting frame. The position of the discharge pipe 400 remains unchanged. The raw material can enter the fixed cylinder 301 under the extrusion of the pushing unit 100. The raw material in the fixed cylinder 301 can be extruded into the mold through the discharge pipe 400, thus completing the extrusion work of the raw material. When the raw material enters the fixed cylinder 301, due to the pushing action of the pushing unit 100 and the caliber limitation of the discharge pipe 400, there will be a pressure inside the raw material. This pressure acts on the piston 302, so that the piston 302 can slide inside the fixed cylinder 301. At this time, the space for storing the raw material inside the fixed cylinder 301 increases. Since the counterweight unit can provide a constant thrust for the piston 302 through the sleeve 303, the pressure of the raw material 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 inside the fixed cylinder 301, thereby automatically adjusting the space for storing the raw material inside the fixed cylinder 301 and keeping the raw material pressure constant. In this way, the extruded raw material can have a constant pressure, avoiding the change of the raw material thickness caused by pressure fluctuation and affecting the floor processing quality.

[0092] As shown Figures 7 to 8 in the figure, the counterweight unit includes:

[0093] A first rack 304, which is slidably installed 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;

[0094] A tooth column 305, which is rotatably installed on the outer wall of the fixed cylinder 301, and the tooth column 305 is meshed with the first rack 304;

[0095] A second rack 306, which moves vertically and is meshed with the tooth column 305. A counterweight is arranged at the top of the second rack 306;

[0096] The side plate 307 is fixed to the outer ring 101, and the second rack 306 is vertically slidably mounted on the side plate 307;

[0097] The side plate 307 provides guidance and support for the second rack 306. Due to gravity, the counterweight and the second rack 306 will provide a lateral thrust for the first rack 304 through the tooth column 305. 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 action of gravity, the thrust of the piston 302 on the raw material can be kept constant, which can improve the stability of the thrust.

[0098] When the piston 302 needs to provide different magnitudes of thrust to the raw material, it can be achieved by changing the acting force of the counterweight on the second rack 306. Specifically, as Figure 8 shown, the counterweight includes:

[0099] The vertical groove plate 308 is vertically fixed to the outer wall of the outer ring 101;

[0100] The counterweight block 309 is vertically slidably mounted on the vertical groove plate 308, and there is a frictional force between the counterweight block 309 and the vertical groove plate 308;

[0101] The telescopic rod 310 is used to connect the second rack 306 and the counterweight block 309. The telescopic rod 310 is inclined, and the fixed end and the movable end of the telescopic rod 310 are locked by a set screw;

[0102] 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 length of the telescopic rod 310 is locked by the set screw thereon, due to the inclination of the telescopic rod 310, the telescopic rod 310 will generate a lateral thrust on the counterweight block 309 by its own gravity. Since there is a frictional force between the counterweight block 309 and the vertical groove plate 308, the frictional force will share part of the force of the counterweight block 309 and the telescopic rod 310 in the vertical direction, and the remaining force will directly act on the second rack 306, thereby providing a counterweight for the second rack 306; when it is necessary to adjust the counterweight, the set 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, thereby changing the frictional force between the counterweight block 309 and the vertical groove plate 308, and indirectly adjusting the counterweight force acting on the second rack 306;

[0103] It should be pointed out here that this structure realizes the adjustment of the counterweight by using the gravity and the way of sharing and adjusting the 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.

[0104] As Figure 8As shown, a sliding plate 311 is slidably arranged on the vertical groove plate 308. The sliding plate 311 is connected to the counterweight 309 through an elastic sheet 312. The elastic sheet 312 provides a basic thrust for the counterweight 309, so that a basic frictional force is generated between the vertical groove plate 308 and the counterweight 309. Since the frictional force between the vertical groove plate 308 and the counterweight 309 is adjustable, the counterweight 309 can move horizontally within a small range on the vertical groove plate 308. Then, the vertical groove plate 308 and the counterweight 309 need to be relatively independent, and this independence will cause the counterweight 309 to break away from the vertical groove plate 308. To avoid this phenomenon, it is necessary to use the sliding plate 311 and the elastic sheet 312 to limit the counterweight 309 so that the counterweight 309 remains on the vertical groove plate 308. When the counterweight 309 moves, it will drive the sliding plate 311 and the elastic sheet 312 to move.

[0105] 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. Then the raw material pressure at this time cannot meet the production requirements. To avoid this phenomenon, structures such as Figure 7 and Figure 8 can be adopted. The end of the discharge pipe 400 facing the outer ring 101 is sealed. A plurality of material guiding holes 401 are formed on the outer wall of the discharge pipe 400. A spring 313 for buffering the second rack 306 is arranged on the side plate 307. To cooperate with the spring 313, the second rack 306 can be set in a right-angled shape, and the top of the second rack 306 is horizontal. In the natural state, the inner wall of the sleeve 303 seals the material guiding holes 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. At this time, the second rack 306 rises. When the piston 302 and the sleeve 303 move and the material guiding holes 401 are exposed in the fixed cylinder 301, the raw material in the fixed cylinder 301 can enter the discharge pipe 400 through the material guiding holes 401. At this time, the raw material starts the normal extrusion work, 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 only when the second rack 306 and the counterweight on it reach a certain height can the raw material extrusion work start. The spring 313 on the side plate 307 can provide a buffering effect for the second rack 306.

[0106] During the process of transporting the raw material in the fixed cylinder 301, in order to make the raw material near the inner wall of the fixed cylinder 301 and the raw material in the middle of the fixed cylinder 301 form an intersecting flow to improve the uniformity of the raw material, structures such as Figure 9In the manner shown, the uniform pressure assisting structure 300 further includes a plurality of rotating columns 314. The plurality of rotating columns 314 are annularly distributed around the axis of the fixed cylinder 301 within the fixed cylinder 301. A spiral blade 315 is provided on the outer wall of the rotating column 314. The end of the rotating column 314 passes through the piston 302 and extends out. The rotating column 314 is rotatably connected to the piston 302. When the rotating column 314 rotates, it will stir the raw materials in the fixed cylinder 301 through the spiral blade 315. Since the plurality of spiral blades 315 are annularly distributed 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, while the other side is close to the middle of the fixed cylinder 301. In this way, the spiral blade 315 can alternately convey and stir the raw materials near the inner wall of the fixed cylinder 301 and in the middle of the fixed cylinder 301, so as to ensure the overall uniformity of the raw materials in the fixed cylinder 301.

[0107] As Figure 7 shown, the uniform pressure assisting structure 300 further includes:

[0108] A plurality of prisms 316, located outside the fixed cylinder 301, are respectively slidably inserted into the plurality of rotating columns 314;

[0109] A plurality of second transmission wheels 317 are respectively installed on the plurality of prisms 316. An annular tooth groove is formed on the circumferential outer wall of the second transmission wheel 317;

[0110] A power unit for providing power for the rotation of the sleeve 303;

[0111] Wherein, the first rack 304 is rotatably connected to the sleeve 303. An outer edge 318 is provided at the end of the fixed cylinder 301 away from the outer ring 101. Teeth are provided on the outer edge 318. The teeth on the outer edge 318 are meshed with the teeth on the second transmission wheel 317. The inner wall of the tooth groove on the second transmission wheel 317 will limit the outer edge 318, so as to limit the position of the second transmission wheel 317 through the fixed cylinder 301, so that the tooth groove on the second transmission wheel 317 and the teeth on the outer edge 318 always remain in a meshed state. When the power unit drives the sleeve 303 to rotate, it will drive the piston 302 and the plurality of 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 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. When the piston 302 moves horizontally, 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.

[0112] As Figure 7 shown, the power unit includes:

[0113] A second motor 319 fixed on the fixed cylinder 301;

[0114] Two third drive wheels 320, one third drive wheel 320 is installed on the output end of the second motor 319, and the other third drive wheel 320 is slidably installed on the sleeve 303 along the axis direction of the sleeve 303, and the sleeve 303 rotates synchronously with the third drive wheel 320 thereon;

[0115] A drive belt 321, sleeved on the two third drive wheels 320 and used to transmit power to the two third drive wheels 320;

[0116] When the second motor 319 operates, it drives the third drive wheel 320 and the drive belt 321 to transmit power, thereby driving the sleeve 303 to rotate. When the piston 302 and the sleeve 303 move laterally, the sleeve 303 and the third drive wheel 320 thereon slide relative to each other and maintain synchronous rotation. Of course, in order to prevent the drive belt 321 from disengaging from the third drive wheel 320, two retaining edges can be provided on each third drive wheel 320 to improve the stability of the transmission.

[0117] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
