Description

Technical Field

[0001] The invention relates to the technical field of hollow plate processing, in particular to a hollow plate extrusion device. Background Art

[0002] As a new type of material with the advantages of light weight, non-toxic, pollution-free, shockproof, anti-aging, corrosion-resistant, and rich colors, hollow board is currently mainly used in electronics, packaging, machinery, light industry, postal services, food, medicine, pesticides, home appliances and other industries, and has a wide range of uses.

[0003] At present, with the increase in market demand for hollow boards, the improvement of corresponding equipment for producing hollow boards has become a key topic for researchers in this field. For example, from the actual processing situation, it is known that in the production process of hollow boards, the extrusion device is one of the more commonly used equipment, but the shearing process in the later stage of processing often causes uneven cuts. After investigating the cause, it was found that the hollow board is subjected to unidirectional pressure from top to bottom when being sheared. If the cutter is not sharp enough, it will cause the hollow board to bend downward to a certain extent before being strongly sheared. Secondly, during the reciprocating shearing process of the cutter, some hollow board raw materials will remain on the surface of the cutter, affecting the sharpness of the cutter and the smoothness of the shearing, which will cause the cut to be not smooth, and ultimately have an adverse effect on the overall process. Summary of the invention

[0004] The present invention provides a hollow plate extrusion device, which solves the problems raised in the above background technology.

[0005] The present invention provides the following technical solutions: a hollow plate extrusion device, comprising an extruder body, an extruder head installed on one side of the extruder body, a hollow plate extruded in the extruder head, a support platform arranged outside one side of the extruder head, a first linkage plate, a hollow seat, and a lead screw transmission assembly arranged on the top of the support platform, an output structure inside the lead screw transmission assembly is connected to the top of the first linkage plate in transmission, a cutter is installed at the bottom of the first linkage plate, and a cutting plate aligned with the cutter is installed inside the top of the hollow seat;

[0006] A second constraint rod is arranged on the top of the support platform, and one end of the second constraint rod passes through the corner structure of the bottom of the hollow seat and the corner structure of the first linkage plate in sequence and extends to the top outside of the first linkage plate. A meshing linkage assembly and a transition cylinder are arranged between the hollow seat and the first linkage plate. The meshing linkage assembly includes a first transmission gear, and the external meshing transmission of the first transmission gear has two opposite spur gear plates, one end of the two spur gear plates are respectively fixedly connected to the bottom surface of the first linkage plate and the bottom surface of the hollow seat, a support rod is fixedly connected between the surface of the transition cylinder and the top surface of the support platform, and the interior of the transition cylinder is movably connected to the first transmission gear and the two spur gear plates.

[0007] The front and rear ends of the top of the hollow seat are both provided with sliding grooves, the two ends of the cutting plate are respectively clamped in the inside of the two sliding grooves, and the ends of the cutting plate are fixedly connected with threaded rods, and the surfaces of the two threaded rods are threadedly connected with limit nuts that can be fitted and connected with the surface of the hollow seat. The cutting plate can be used in two states of top pressing and giving way inside the hollow seat, alternately to meet different usage requirements.

[0008] The screw transmission assembly comprises a screw, a transmission nut, a second linkage plate and a brake servo motor. The output end of the brake servo motor is transmission-connected to one end of the top of the screw, and a support frame is fixedly installed between the shell surface of the brake servo motor and the top of the second constraint rod. The transmission nut is threadedly connected to the surface of the screw. The second linkage plate is installed between the bottom of the transmission nut and the top of the first linkage plate as the output structure of the screw transmission assembly, so that the first linkage plate can be synchronously raised and lowered with the transmission nut. The screw transmission assembly serves as the power for the first linkage plate to automatically move away from or close to the hollow seat, which can improve the automation performance of the overall device.

[0009] Preferably, a through hole is provided in one end of the two spur gear plates, a first constraint rod is fixedly connected to the bottom surface of the first linkage plate and the bottom surface of the hollow seat, and one end of the two first constraint rods is respectively clamped in the two through holes, and both end ends of the first transmission gear are optical axis structures and are respectively movably sleeved in the side walls on both sides of the middle part of the transition tube, and the interior of the transition tube is provided with two first clearance grooves that can be movably sleeved with the two spur gear plates respectively, and two second clearance grooves that can be movably sleeved with the two first constraint rods respectively, thereby avoiding structural interference.

[0010] The selected part has two corresponding first transmission shafts movably sleeved inside the hollow seat, and transition sleeves are fixedly sleeved on the surfaces of the two first transmission shafts, and rubber scrapers capable of reciprocating rotation inside the hollow seat are fixedly connected on the surfaces of the two transition sleeves, and the number of the rubber scrapers is not less than two and they are evenly arranged and installed on the surfaces of the two transition sleeves, and the transition sleeve serves as a transition support so that the multiple rubber scrapers can rotate synchronously with the first transmission shaft, thereby providing structural conditions for the subsequent multiple rubber scrapers to move the cutters to the structure inside the hollow seat for scraping and cleaning, and the side structure of the rubber scraper away from the transition sleeve is set to an L-shaped folding structure, which is convenient for the subsequent flipping and scraping of the hollow plate raw material attached to the surface of the shearing structure at the bottom of the cutter, and the L-shaped folding structure is provided with a through-state drainage hole at the right-angle flipping position, so that the residual materials scraped and cleaned out subsequently can be temporarily stored.

[0011] The two ends of the first transmission shafts are carefully selected to extend to the outside of the hollow seat, and the second transmission gears are fixedly sleeved on the outside of one end of the two first transmission shafts, and one end of one of the first transmission shafts is transmission-connected to an auxiliary motor, and the two second transmission gears are meshingly connected to each other, and a support seat is fixedly connected between the shell surface of the auxiliary motor and the surface of the hollow seat. The combined use of the two second transmission gears, the auxiliary motor and the first transmission shaft can enable the first transmission shaft and the transition sleeve associated with the first transmission shaft, and multiple rubber scrapers to automatically contact and scrape and clean the structure where the cutter moves to the inside of the hollow seat, thereby eliminating adverse factors in the reciprocating shearing process of the cutter and maintaining the smooth shearing effect of the cutter for a long time.

[0012] The surfaces of the two first transmission shafts are fixedly connected with first blades movably sleeved inside the hollow seat, and the number of the first blades is not less than two. The linkage between the first blades and the first transmission shaft can generate airflow in the air inside the hollow seat, and then the structure of the cutter moved to the inside of the hollow seat is cooled by air blowing, thereby reducing the thermal wear rate of the cutter during shearing and maintaining a sharp use effect for a long time. There is a make way space between the first blades and the corresponding rubber scraper to avoid structural interference during operation.

[0013] The optical axis structure surface of the first transmission gear is fixedly connected with a second fan blade movably sleeved inside the transition tube, and the number of the second fan blade is not less than two. After the second fan blade rotates in conjunction with the first transmission gear, it can generate airflow to dissipate the meshing friction between the first transmission gear and the two spur gear plates, thereby ensuring the service life of the first transmission gear and the two spur gear plates.

[0014] The middle part of the transition tube is fixedly connected with a guide tube which is connected with its own space. The output direction of the guide tube is toward the hollow plate, and there is a makeshift space between the guide tube and the nearest straight tooth plate. The guide tube guides the wind output after the second fan blade rotates to the surface of the hollow plate, and then preliminarily cools the newly processed hollow plate, thereby improving the structure of the hollow plate and creating favorable conditions for subsequent smooth shearing.

[0015] Preferably, two second constraint rods are provided, and one end of one of the second constraint rods sequentially penetrates the corner structure at the front end of the bottom of the hollow seat and the corner structure at the front end of the first linkage plate and extends to the top outside of the first linkage plate, and one end of the other second constraint rod sequentially penetrates the corner structure at the rear end of the bottom of the hollow seat and the corner structure at the rear end of the first linkage plate and extends to the top outside of the first linkage plate. The provision of two first linkage plates can further enhance the stability between the hollow seat and the first linkage plate which are reciprocating close to or apart, and maintain the characteristics of sustainable use of the hollow seat and the first linkage plate.

[0016] The present invention has the following beneficial effects:

[0017] 1. The present invention combines and drives the first linkage plate and the hollow seat through the screw transmission assembly and the meshing linkage assembly, so that the cutter associated with the first linkage plate and the cutting plate associated with the hollow seat can be automatically sheared at the position of the hollow plate, and the specific shearing depth of the cutter is automatically regulated by the screw transmission assembly. During the shearing process, the hollow plate is first clamped by the cutter and the cutting plate, and then sheared by the cutter. This can fully ensure the flatness and neatness of the incision and solve the problems existing in the prior art.

[0018] 2. The present invention forms a relative cleaning structure by setting two first transmission shafts, transition sleeves respectively installed on the two first transmission shafts, and a rubber scraper. Then, when the cutter moves to the inside of the hollow seat for shearing operation, the relative cleaning structure can automatically scrape and clean the bottom structure of the cutter set to the inside of the hollow seat under the corresponding transmission of the auxiliary motor and the two second transmission gears, thereby avoiding the hollow plate raw materials adhering to the cutting surface of the bottom structure of the cutter, maintaining the neat shearing effect of the cutter during long-term operation, and creating more favorable conditions for the smoothness of the incision.

The surfaces of the two threaded rods are threadedly connected with limit nuts that can be connected to the surface of the hollow seat 6. The cutting plate 8 can be used in the hollow seat 6 in two alternate use states: top pressing use and giving way use, to meet different use requirements;

[0033] A second restraining rod 10 is provided on the top of the supporting platform 4, one end of which passes through the corner structure at the bottom of the hollow seat 6 and the corner structure of the first linkage plate 5 in sequence and extends to the outer side of the top of the first linkage plate 5;

[0034] There are two second restraining rods 10, and one end of one of the second restraining rods 10 sequentially penetrates the corner structure at the front end of the bottom of the hollow seat 6 and the corner structure at the front end of the first linkage plate 5 and extends to the top outer side of the first linkage plate 5, and one end of the other second restraining rod 10 sequentially penetrates the corner structure at the rear end of the bottom of the hollow seat 6 and the corner structure at the rear end of the first linkage plate 5 and extends to the top outer side of the first linkage plate 5. The arrangement of the two first linkage plates 5 can further enhance the stability between the reciprocating close or separated hollow seat 6 and the first linkage plate 5, and maintain the characteristics of sustainable use of the hollow seat 6 and the first linkage plate 5;

[0035] A meshing linkage assembly 9 and a transition cylinder 19 are arranged between the hollow seat 6 and the first linkage plate 5. The meshing linkage assembly 9 includes a first transmission gear 91. The external meshing transmission of the first transmission gear 91 has two opposite spur plates 92. One end of the two spur plates 92 is fixedly connected to the bottom surface of the first linkage plate 5 and the bottom surface of the hollow seat 6, respectively. A support rod is fixedly connected between the surface of the transition cylinder 19 and the top surface of the support platform 4, and the interior of the transition cylinder 19 is movably connected to the first transmission gear 91 and the two spur plates 92, and the two spur plates 92 are fixedly connected to the bottom surface of the first linkage plate 5 and the bottom surface of the hollow seat 6. A through hole is provided in one end of the plate 92, and the bottom surface of the first linkage plate 5 and the bottom surface of the hollow seat 6 are fixedly connected with a first constraint rod 93, and one end of the two first constraint rods 93 is respectively clamped in the two through holes, and the two ends of the first transmission gear 91 are optical axis structures and are respectively movably sleeved in the side walls on both sides of the middle part of the transition tube 19, and the interior of the transition tube 19 is provided with two first clearance grooves that can be movably sleeved with the two straight tooth plates 92, and two second clearance grooves that can be movably sleeved with the two first constraint rods 93;

[0036] Two corresponding first transmission shafts 12 are movably sleeved inside the hollow seat 6, and transition sleeves 13 are fixedly sleeved on the surfaces of the two first transmission shafts 12. Rubber scrapers 14 that can reciprocate inside the hollow seat 6 are fixedly connected on the surfaces of the two transition sleeves 13. The number of rubber scrapers 14 is not less than two and they are arranged and installed on the surfaces of the two transition sleeves 13 in an evenly distributed manner. The transition sleeves 13 serve as transition supports to enable multiple rubber scrapers 14 to rotate synchronously with the first transmission shaft 12, thereby providing structural conditions for the subsequent multiple rubber scrapers 14 to move the cutter 7 to the structure inside the hollow seat 6 for scraping and cleaning;

[0037] The ends of the two first transmission shafts 12 at both ends extend to the outside of the hollow seat 6, and the second transmission gears 15 are fixedly sleeved on the outside of one end of the two first transmission shafts 12, and one end of one of the first transmission shafts 12 is transmission-connected to an auxiliary motor 16, and the two second transmission gears 15 are meshed and connected with each other, and a support seat is fixedly connected between the shell surface of the auxiliary motor 16 and the surface of the hollow seat 6. The combination of the two second transmission gears 15, the auxiliary motor 16 and the first transmission shaft 12 can make the first transmission shaft 12 associated with the first transmission shaft 12 The transition sleeve 13 and multiple rubber scrapers 14 automatically contact and scrape the structure inside the hollow seat 6 when the cutter 7 moves, thereby eliminating adverse factors in the reciprocating shearing process of the cutter 7 and maintaining the smooth shearing effect of the cutter 7 for a long time. The side structure of the rubber scraper 14 away from the transition sleeve 13 is set as an L-shaped folding structure, which is convenient for subsequent flipping and scraping of the hollow plate 3 raw materials attached to the surface of the shearing structure at the bottom of the cutter 7, and the L-shaped folding structure is provided with a through-state drainage hole at the right-angle flipping position, so that the residual materials scraped and cleaned out later can be temporarily stored;

[0038] The surfaces of the two first transmission shafts 12 are fixedly connected with first blades 17 that are movably sleeved inside the hollow seat 6, and the number of the first blades 17 is not less than two. The linkage between the first blades 17 and the first transmission shaft 12 can generate airflow in the air inside the hollow seat 6, and then the cutter 7 is moved to the structure inside the hollow seat 6 for air blowing cooling, thereby reducing the thermal wear rate of the cutter 7 during the shearing process and maintaining a sharp use effect for a long time. There is a clearance space between the first blades 17 and the corresponding rubber scraper 14 to avoid structural interference during operation;

[0039] The optical axis structure surface of the first transmission gear 91 is fixedly connected with a second fan blade 18 movably sleeved inside the transition tube 19. The number of the second fan blade 18 is not less than two. After the second fan blade 18 rotates in conjunction with the first transmission gear 91, an airflow can be generated to dissipate the meshing friction between the first transmission gear 91 and the two spur gear plates 92 by air blowing, thereby ensuring the service life of the first transmission gear 91 and the two spur gear plates 92. The middle part of the transition tube 19 is fixedly sleeved with a guide tube 20 that is connected to its own space. The output direction of the guide tube 20 is toward the hollow plate 3, and there is a makeshift space between the guide tube 20 mounted on the end of the transition tube 19 and the nearest spur gear plate 92. The guide tube 20 guides the wind output after the second fan blade 18 rotates to the surface of the hollow plate 3, and then preliminarily cools the newly processed hollow plate 3, improves the structure of the hollow plate 3, and creates favorable conditions for subsequent smooth shearing.

[0040] Working principle:

[0041] Embodiment 1

[0042] In the case where the guide tube 20 and the second fan blade 18 are not provided, the brake servo motor 114 inside the screw transmission assembly 11 is started, and the output end of the brake servo motor 114 drives the screw 111 to rotate synchronously, and then the screw 111 and the transmission nut 112 are meshed and driven, so that the transmission nut 112 drives the second linkage plate 113, the first linkage plate 5 and the cutter 7 to automatically move downward;

[0043] During the downward movement of the first linkage plate 5, a spur plate 92 that moves synchronously with the first linkage plate 5 will mesh with the first transmission gear 91 for transmission, and then another spur plate 92 that meshes with the first transmission gear 91 drives the hollow seat 6 and the cutting plate 8 to move upward synchronously and move close to the cutter 7, and the close movement of the first linkage plate 5 and the hollow seat 6 stops after the cutter 7 contacts the cutting plate 8 to complete the automatic shearing of the hollow plate 3, and the hollow plate 3 is first clamped by the cutter 7 and the cutting plate 8 during the shearing process, and then pressed and sheared by the cutter 7, thereby fully ensuring the flatness and neatness of the incision;

[0044] After a cycle of shearing operation on the hollow plate 3 is completed, the brake servo motor 114 is output in the reverse direction, and the output end of the brake servo motor 114 drives the lead screw 111 to rotate synchronously, and then the meshing transmission between the lead screw 111 and the transmission nut 112 is used to make the transmission nut 112 drive the second linkage plate 113, the first linkage plate 5 and the cutter 7 to automatically move up and reset. Similarly, a spur plate 92 that moves synchronously with the first linkage plate 5 will mesh with the first transmission gear 91 for transmission, and then another spur plate 92 meshing with the first transmission gear 91 drives the hollow seat 6 and the cutting plate 8 to move down and reset synchronously, thereby returning each component to its initial position and preparing for the next shearing operation. The reciprocating close or separated cutter 7 and cutting plate 8 can adapt to the shearing requirements of hollow plates 3 of different thicknesses while avoiding output interference facing hollow plates 3 of different thicknesses.

[0045] Embodiment 2

[0046] In the case where the guide tube 20 and the second blade 18 are provided, the automatic shearing of the hollow plate 3 by the cutter 7 and the cutting plate 8 can be realized according to the steps of the first embodiment above. However, during the reciprocating movement of the two spur plates 92 together with the corresponding first linkage plate 5 and the corresponding hollow seat 6, the first transmission gear 91 of the transition meshing transmission will drive the second blade 18 to rotate synchronously, thereby generating airflow inside the transition cylinder 19.

[0047] The airflow generated by the second fan blade 18 first blows air to cool the meshing point between the first transmission gear 91 and the two spur plates 92, thereby reducing the thermal wear rate of the meshing between the first transmission gear 91 and the two spur plates 92. Then the airflow will be blown toward the hollow plate 3 through the guide tube 20, thereby preliminarily cooling the newly processed hollow plate 3, improving the structure of the hollow plate 3, and thus creating favorable conditions for subsequent smooth shearing, further ensuring the smooth shearing effect of the cutter 7 on the hollow plate 3.

[0048] Embodiment 3

[0049] When the raw material of the hollow plate 3 is attached to the shearing structure surface at the bottom of the cutter 7, the shearing mode of the cutter 7 can be adjusted as follows;

[0050] Twist the nuts outside the two ends of the cutting plate 8 and temporarily move the two nuts away from the hollow seat 6. After completion, push the cutting plate 8 to make the cutting plate 8 close to the side structure on one side or the other side of the hollow seat 6, and end the use state of the cutter 7 being aligned. Then, reset and twist the two nuts to limit and lock the moved cutting plate 8.

[0051] After the displacement adjustment of the cutting plate 8 is completed, the shearing demand of the hollow plate 3 is met, and the brake servo motor 114 inside the screw transmission assembly 11 is started, and the output end of the brake servo motor 114 drives the screw 111 to rotate synchronously, and then the screw 111 and the transmission nut 112 are meshed and driven, so that the transmission nut 112 drives the second linkage plate 113, the first linkage plate 5 and the cutter 7 to automatically move downward;

[0052] During the downward movement of the first linkage plate 5, a spur plate 92 that moves synchronously with the first linkage plate 5 will mesh with the first transmission gear 91 for transmission, and then another spur plate 92 that meshes with the first transmission gear 91 will drive the hollow seat 6 and the cutting plate 8 to move upward synchronously and move close to the cutter 7, and the close movement of the first linkage plate 5 and the hollow seat 6 ends after the bottom structure of the cutter 7 completes the automatic shearing of the hollow plate 3 and moves between the two first transmission shafts 12, and the hollow plate 3 is first clamped by the cutter 7 and the hollow seat 6 during the shearing process, and then pressed and sheared by the cutter 7, thereby fully ensuring the flatness and neatness of the incision;

[0053] After the bottom structure of the cutter 7 is set into the hollow seat 6, the auxiliary motor 16 will be started synchronously, and the output end of the auxiliary motor 16 will drive the corresponding first transmission shaft 12 to rotate synchronously. Under the mutual meshing transmission of the two second transmission gears 15, the other first transmission shaft 12 will also rotate synchronously and in the opposite direction to the rotation direction of the first transmission shaft 12 that rotates initially, and finally the rubber scrapers 14 set on the two first transmission shafts 12 will automatically and reciprocally scrape the hollow board 3 materials attached to the two cutting surfaces of the bottom structure of the cutter 7 in a counterclockwise manner, so as to keep the bottom structure of the cutter 7 clean and create favorable conditions for the long-term smooth shearing of the cutter 7;

[0054] After a cycle of shearing operation on the hollow plate 3 is completed, the brake servo motor 114 is reversed, and the output end of the brake servo motor 114 drives the lead screw 111 to rotate synchronously, and then the meshing transmission between the lead screw 111 and the transmission nut 112 is utilized to make the transmission nut 112 drive the second linkage plate 113, the first linkage plate 5 and the cutter 7 to automatically move up and reset. Similarly, a spur plate 92 that moves synchronously with the first linkage plate 5 will mesh with the first transmission gear 91 for transmission, and then another spur plate 92 meshing with the first transmission gear 91 drives the hollow seat 6 to move down and reset synchronously, thereby returning each component to its initial position and preparing for the next shearing operation.
