Description

Technical Field

[0001] The invention belongs to the technical field of polyurethane glass fiber composite material processing, and specifically relates to a pultrusion device for producing polyurethane glass fiber composite material. Background Art

[0002] Polyurethane fiberglass composite material is a composite material composed of polyurethane resin and glass fiber. It combines the advantages of two materials: polyurethane resin has chemical resistance and wear resistance, and glass fiber provides good mechanical strength and rigidity. Polyurethane resin has excellent chemical corrosion resistance and can be used for a long time in harsh environments. The combination of polyurethane and glass fiber can improve the wear resistance of the material and is suitable for high-wear application scenarios. Compared with traditional metal materials, polyurethane fiberglass composite materials have a lower density, making the overall structure lighter.

[0003] In the prior art, when the polyurethane glass fiber composite material is extruded at the mold position, the extruded material needs to be pulled by a pulling device. During extrusion, the extruder is greatly affected by the material, and its extrusion speed changes. The existing pulling equipment can only provide a constant pulling speed to pull the material, which causes the extrusion speed and the pulling speed to be inconsistent, affecting the quality of the product. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a pultrusion device with adjustable pulling speed.

[0005] The technical solution adopted to solve the above technical problems is: a pultrusion device for the production of polyurethane glass fiber composite materials, including a pulling platform, two traction chutes are opened on one side of the upper surface of the pulling platform, and the main traction structure and the auxiliary traction structure are respectively arranged inside the two traction chutes.

[0006] Through the above technical solution, the pulling platform can be installed to support the main pulling structure, the auxiliary pulling structure and the cutter. The main pulling structure and the auxiliary pulling structure slide in the pulling chute position to pull the extruded polyurethane glass fiber.

[0007] A cutting slot is provided on the upper surface of the pulling platform at the side of the auxiliary traction structure away from the main traction structure, a cutter is slidably connected to the inner wall of the cutting slot, and a synchronous linkage mechanism is provided between the cutter and the auxiliary traction structure.

[0008] Through the above technical solution, the cutting groove limits the horizontal sliding of the cutter, so that the cutter moves synchronously with the main traction structure and the auxiliary traction structure to achieve cutting of the pulled glass fiber composite material. The synchronous linkage mechanism enables the main traction structure and the auxiliary traction structure to provide power to the cutter through the auxiliary traction structure when moving, without the need for an additional power source, and with high synchronization.

[0009] Furthermore, the main traction structure and the auxiliary traction structure both include a traction body slidably connected to the inner wall of the traction slot, and floating guide pillars are fixedly connected to the four corner positions between the inner top wall and the inner bottom wall of the traction body. A traction pressure block with guide holes penetrating through the four corners is arranged on the inner side of the traction body, and the guide holes of the traction pressure block are slidably connected to the floating guide pillars at the corresponding positions.

[0010] Through the above technical solution, the floating guide column can realize the vertical upward and downward movement of the traction pressing block at the position of the traction main body, so that the traction pressing block can be pressed downward to clamp the extruded polyurethane glass fiber composite material for traction.

[0011] Furthermore, a traction hydraulic cylinder is fixedly connected to the middle position of the upper surface of the traction body, and the telescopic end of the traction hydraulic cylinder faces downward and penetrates the traction body and is fixedly connected to the upper surface of the traction pressure block. A speed regulating groove is provided in the middle position of the lower surface of the traction pressure block, and the traction pressure block has two symmetrically arranged spring grooves located on both sides of the speed regulating groove.

[0012] Through the above technical solution, the traction hydraulic cylinder provides power for the traction pressing block to move up and down, and by adjusting the stroke of the traction hydraulic cylinder, it can adapt to polyurethane glass fiber composite materials of different thicknesses.

[0013] Furthermore, two symmetrically arranged support guide pillars are fixedly connected to the inner walls of the two spring grooves, a traction block is slidably connected to the inner wall of the speed regulating slide groove, and two symmetrically arranged reset plates are fixedly connected to the middle positions on both sides of the traction blocks. The two reset plates are slidably connected to the support guide pillars at the corresponding positions, and force feedback springs are fixedly connected between the two sides of the reset plates and the inner walls of the spring grooves, and the force feedback springs are concentrically arranged with the support guide pillars.

[0014] Through the above technical scheme, the support guide column can realize the horizontal sliding of the traction block on the inner wall of the speed regulating slide groove to adapt to different extrusion forces. The rubber material is arranged on the lower surface of the traction block, which can effectively protect the polyurethane glass fiber composite material when extruding the polyurethane glass fiber composite material to avoid indentations on the surface of the polyurethane glass fiber composite material. The force feedback spring can make the traction block slide under the action of the force feedback spring when the extrusion force changes.

[0015] Furthermore, a sliding rheostat is fixedly connected to the inner wall of any one of the spring grooves, the slider of the sliding rheostat is fixed to the reset plate at the corresponding position, the traction platform is located in the traction slide groove and is provided with two traction electric slide rails, and the sliders of the two traction electric slide rails are connected to the main traction structure and the auxiliary traction structure at the corresponding positions, and the power source of the traction electric slide rails is electrically controlled by the sliding rheostat.

[0016] When the extrusion force changes, the traction block slides, and the slider of the sliding rheostat is moved by the reset plate at the corresponding position, so the resistance changes and the moving speed of the traction electric slide rail changes, thereby adapting to the extrusion speed of the polyurethane glass fiber composite material. The traction electric slide rail provides power for the sliding traction of the main traction structure and the auxiliary traction structure.

[0017] Furthermore, two symmetrically arranged limiting protrusions are fixedly connected to the inner bottom wall of the traction body, and a linkage slide plate is slidably connected between the two limiting protrusions.

[0018] Through the above technical solution, the limiting protrusion limits the sliding of the linkage slide plate, and the linkage slide plate is adjusted more accurately when the traction force of the traction block changes, avoiding the large friction between the polyurethane glass fiber composite material and the linkage slide plate to affect the adjustment accuracy.

[0019] Furthermore, the synchronous linkage mechanism includes an adjusting control groove, and the adjusting control groove is located on either side of the pulling platform, a through slide groove is opened between the adjusting control groove and the traction slide groove and the cutting slide groove, the traction body side wall position of the auxiliary traction structure is fixedly connected with a limiting guide rod, the limiting guide rod is slidably connected to the inner wall of the through slide groove, the through slide groove is slidably connected with a side shift slide, the side shift slide is fixedly connected to the slide table of the cutter, and a compression spring is fixedly connected between the side shift slide and the inner wall of the adjusting control groove close to the cutter.

[0020] Through the above technical solution, the control pull block can be adjusted through the adjustment control groove, thereby adjusting the effective working length of the bottom slide, and the cutting length of the polyurethane glass fiber composite material can be adjusted. The normal sliding of the limit guide rod and the side shift slide is not affected by the sliding groove. When the auxiliary traction structure moves, the limit guide rod and the bottom slide are driven to move together. When the bottom slide squeezes the side shift slide, the side shift slide drives the cutter to move. When the auxiliary traction structure is reset, the cutter is reset under the action of the compression spring.

[0021] Furthermore, the inner wall of the adjustment control groove is slidably connected to a bottom slide, a positioning adjustment groove is provided on the surface of the bottom slide, a linkage adjustment groove is penetrated through the surface of the bottom slide, the limiting guide rod slides through the linkage adjustment groove, and the bottom slide has positioning adjustment grooves on the upper and lower sides of the linkage adjustment groove.

[0022] Through the above technical solution, the linkage adjustment groove can allow the limiting guide rod to be penetrated, and the positioning adjustment groove cooperates with the positioning block that controls the position of the pull block, so that the bottom slide plate moves together with the limiting guide rod.

[0023] Furthermore, an elastic groove is opened at the center position of one end of the limiting guide rod away from the main traction structure, and a tensioning spring is fixedly connected to the inner wall of the elastic groove, and a control pull block is fixedly connected to the position of the tensioning spring, and two rows of symmetrically arranged positioning blocks are fixedly connected to the side of the control pull block close to the positioning adjustment groove, and the positioning blocks are engaged with the positioning adjustment groove.

[0024] Through the above technical solution, the tension spring allows the control pull block to automatically reset when there is no tension, so that the positioning block fully acts on the positioning adjustment groove.

[0025] The beneficial effects of the present invention are as follows: (1) By setting a force feedback spring and a sliding rheostat, the present invention can provide feedback through the force feedback spring when the extrusion force of the polyurethane glass fiber composite material changes, so that the traction block slides under the action of the force feedback spring, and the slider of the sliding rheostat slides, and then the traction speed of the traction electric slide rail is adjusted by the sliding rheostat, so that the equipment has strong adaptability; (2) By setting a synchronous linkage mechanism, the present invention can adjust the working effective length of the bottom slide by sliding the bottom slide, so that the polyurethane glass fiber composite material can be cut to a specified length. When the auxiliary traction structure moves, the bottom slide moves accordingly, and the bottom slide squeezes the cutter, so that the cutter moves synchronously with the auxiliary traction structure, which can adapt to the traction speed of the auxiliary traction structure, has stronger adaptability, and has high cutting accuracy.

[0035] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0036] like Figure 1-8 As shown, a pultrusion device for producing a polyurethane glass fiber composite material in this embodiment includes a pulling platform 1. Two traction chutes 3 are provided at one side of the upper surface of the pulling platform 1. A main traction structure 2 and an auxiliary traction structure 7 are respectively provided inside the two traction chutes 3. The pulling platform 1 can be installed to support the main traction structure 2, the auxiliary traction structure 7 and the cutter 5. The main traction structure 2 and the auxiliary traction structure 7 slide at the position of the traction chute 3 to pull the extruded polyurethane glass fiber.

[0037] Both the main traction structure 2 and the auxiliary traction structure 7 include a traction body 201 slidably connected to the inner wall of the traction chute 3, and floating guide pillars 203 are fixedly connected to the four corner positions between the inner top wall and the inner bottom wall of the traction body 201. A traction pressure block 202 with guide holes 208 penetrating through the four corners is arranged on the inner side of the traction body 201, and the guide holes 208 of the traction pressure block 202 are slidably connected to the floating guide pillars 203 at the corresponding positions. The floating guide pillars 203 can realize the vertical up and down movement of the traction pressure block 202 at the position of the traction body 201, so that the traction pressure block 202 can be pressed down to clamp the extruded polyurethane glass fiber composite material for traction.

[0038] A traction hydraulic cylinder 207 is fixedly connected to the middle position of the upper surface of the traction body 201, and the telescopic end of the traction hydraulic cylinder 207 faces downward and penetrates the traction body 201 and is fixedly connected to the upper surface of the traction pressure block 202. A speed regulating groove 200 is provided in the middle position of the lower surface of the traction pressure block 202. The traction pressure block 202 has two symmetrically arranged spring grooves 212 located on both sides of the speed regulating groove 200. The traction hydraulic cylinder 207 provides power for the traction pressure block 202 to move up and down, and by adjusting the stroke of the traction hydraulic cylinder 207, it can adapt to polyurethane glass fiber composite materials of different thicknesses.

[0039] Two symmetrically arranged support guide pillars 211 are fixedly connected to the inner wall positions of the two spring grooves 212, and a traction block 206 is slidably connected to the inner wall of the speed regulating slide groove 200. Two symmetrically arranged reset plates 213 are fixedly connected to the middle positions on both sides of the traction block 206. The two reset plates 213 are slidably connected with the support guide pillars 211 at the corresponding positions. A force feedback spring 210 is fixedly connected between the two sides of the reset plate 213 and the inner wall of the spring groove 212, and the force feedback spring 210 is concentrically arranged with the support guide pillar 211. The support guide pillar 211 can enable the traction block 206 to slide horizontally on the inner wall position of the speed regulating slide groove 200 to adapt to different extrusion forces. A rubber material is arranged on the lower surface of the traction block 206, which can effectively protect the polyurethane glass fiber composite material when extruding the polyurethane glass fiber composite material to avoid indentations on the surface of the polyurethane glass fiber composite material. When the extrusion force changes, the traction block 206 slides under the action of the force feedback spring 210.

[0040] A sliding rheostat 209 is fixedly connected to the inner wall of any spring groove 212, and the slider of the sliding rheostat 209 is fixed to the reset plate 213 at the corresponding position. The pulling platform 1 is located in the traction slide groove 3 and is provided with two traction electric slide rails 4, and the sliders of the two traction electric slide rails 4 are connected to the main traction structure 2 and the auxiliary traction structure 7 at the corresponding positions, and the power source of the traction electric slide rail 4 is electrically controlled by the sliding rheostat 209. When the traction block 206 slides, the slider of the sliding rheostat 209 is moved by the reset plate 213 at the corresponding position, and the resistance changes, and the moving speed of the traction electric slide rail 4 changes, thereby adapting to the extrusion speed of the polyurethane glass fiber composite material, and the traction electric slide rail 4 provides power for the sliding traction of the main traction structure 2 and the auxiliary traction structure 7.

[0041] Two symmetrically arranged limiting protrusions 204 are fixedly connected to the inner bottom wall of the traction body 201, and a linkage slide plate 205 is slidably connected between the two limiting protrusions 204. The limiting protrusions 204 limit the sliding of the linkage slide plate 205, and the linkage slide plate 205 can be adjusted more accurately when the traction force of the traction block 206 changes, thereby avoiding the large friction between the polyurethane glass fiber composite material and the linkage slide plate 205 affecting the adjustment accuracy.

[0042] A cutting slot 6 is provided on the upper surface of the pulling platform 1, which is located on the side of the auxiliary traction structure 7 away from the main traction structure 2. The inner wall of the cutting slot 6 is slidably connected to a cutter 5. A synchronous linkage mechanism is provided between the cutter 5 and the auxiliary traction structure 7. The cutting slot 6 limits the horizontal sliding of the cutter 5, so that the cutter 5 moves synchronously with the main traction structure 2 and the auxiliary traction structure 7 to achieve cutting of the pulled glass fiber composite material. The synchronous linkage mechanism enables the main traction structure 2 and the auxiliary traction structure 7 to provide power to the cutter 5 through the auxiliary traction structure 7 when moving, without the need for an additional power source, and with high synchronization.

[0043] The synchronous linkage mechanism includes an adjustment control groove 10, and the adjustment control groove 10 is located on either side of the pulling platform 1, a through slide groove 14 is provided between the adjustment control groove 10 and the traction slide groove 3 and the cutting slide groove 6, a limit guide rod 13 is fixedly connected to the side wall of the traction body 201 of the auxiliary traction structure 7, the limit guide rod 13 is slidably connected to the inner wall of the through slide groove 14, a side shift slide plate 16 is slidably connected to the through slide groove 14, the side shift slide plate 16 is fixedly connected to the slide table of the cutter 5, and a compression spring is fixedly connected between the side shift slide plate 16 and the inner wall of the adjustment control groove 10 close to the cutter 5. The spring 15 can adjust the control pull block 12 through the adjustment control groove 10, thereby adjusting the effective working length of the bottom slide 8, and can adjust the cutting length of the polyurethane glass fiber composite material. The slide groove 14 is passed through so that the normal sliding of the limit guide rod 13 and the side shift slide 16 is not affected. When the auxiliary traction structure 7 moves, the limit guide rod 13 and the bottom slide 8 are driven to move together. When the bottom slide 8 squeezes the side shift slide 16, the side shift slide 16 drives the cutter 5 to move. When the auxiliary traction structure 7 is reset, the cutter 5 is reset under the action of the compression spring 15.

[0044] The inner wall of the adjustment control groove 10 is slidably connected with the bottom slide 8, a positioning adjustment groove 11 is opened on the surface of the bottom slide 8, a linkage adjustment groove 9 is penetrated on the surface of the bottom slide 8, a limiting guide rod 13 penetrates and slides with the linkage adjustment groove 9, and the bottom slide 8 is provided with positioning adjustment grooves 11 at the upper and lower sides of the linkage adjustment groove 9, the linkage adjustment groove 9 allows the limiting guide rod 13 to be penetrated, and the positioning adjustment groove 11 cooperates with the positioning block 17 that controls the position of the pull block 12, so that the bottom slide 8 moves with the limiting guide rod 13.

[0045] An elastic groove 18 is opened at the center position of one end of the limiting guide rod 13 away from the main traction structure 2, and a tensioning spring 19 is fixedly connected to the inner wall of the elastic groove 18, and a control pull block 12 is fixedly connected to the tensioning spring 19. The control pull block 12 is fixedly connected to two rows of symmetrically arranged positioning blocks 17 on the side close to the positioning adjustment groove 11, and the positioning blocks 17 are engaged with the positioning adjustment groove 11. The tensioning spring 19 makes the control pull block 12 automatically reset when there is no tension, so that the positioning block 17 fully acts on the positioning adjustment groove 11.

[0046] The working principle of this embodiment is as follows: pull the control pull block 12 to lengthen the tension spring 19 and separate the positioning block 17 from the positioning adjustment slot 11, so that the bottom slide plate 8 can be slid to adapt to the cutting length of the polyurethane glass fiber composite material. Then release the control pull block 12, and under the action of the tension spring 19, the control pull block 12 is reset, so that the positioning block 17 and the positioning adjustment slot 11 are reset, so that the bottom slide plate 8 is relatively fixed;

[0047] The polyurethane glass fiber composite material extruded by the extruder passes through the traction pressing block 202 and the linkage slide plate 205 of the main traction structure 2 and the auxiliary traction structure 7, and the traction hydraulic cylinder 207 at the position of the main traction structure 2 is started, so that the traction pressing block 202 presses the polyurethane glass fiber composite material at the position of the main traction structure 2, and the main traction structure 2 is driven to move through the traction electric slide rail 4 at the corresponding position. At this time, the extrusion force is consistent with the traction force of the main traction structure 2, and the polyurethane glass fiber composite material is pulled normally;

[0048] When the extrusion force changes, the traction block 206 and the linkage slide plate 205 move under the action of the force feedback spring 210, and the reset plate 213 drives the slider of the sliding rheostat 209 to move, and the resistance of the sliding rheostat 209 changes, and the corresponding traction speed of the traction electric slide rail 4 changes, thereby adapting to the extrusion force of the polyurethane glass fiber composite material extruder, and ensuring the quality of the polyurethane glass fiber composite material;

[0049] When the main traction structure 2 moves to the position of the auxiliary traction structure 7, the traction hydraulic cylinder 207 of the main traction structure 2 is reset, so that the traction pressure block 202 rises and resets, and the traction hydraulic cylinder 207 of the auxiliary traction structure 7 is pressed down, and the traction pressure block 202 at the position of the auxiliary traction structure 7 is pressed down to compress the polyurethane glass fiber composite material, and the polyurethane glass fiber composite material is pulled by the auxiliary traction structure 7, and the main traction structure 2 slides back to reset, and when the auxiliary traction structure 7 pulls the polyurethane glass fiber composite material, when the bottom slide plate 8 touches the side shift slide plate 16, it will squeeze the cutter 5, so that the cutter 5 cuts the polyurethane glass fiber composite material, when the auxiliary traction structure 7 moves to the cutting slide groove 6 position, the main traction structure 2 is switched to pull the polyurethane glass fiber composite material, and the auxiliary traction structure 7 is reset and moved back, then the side shift slide plate 16 loses the squeezing force, and the cutter 5 is reset under the action of the compression spring 15.
