Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation cotton processing, in particular to a material pressing mechanism for cutting rubber and plastic thermal insulation cotton. Background Technique

[0002] Rubber and plastic thermal insulation cotton is a new type of thermal insulation material composed of a mixture of rubber and plastic, with excellent thermal insulation and fire prevention properties. It is widely used in many fields such as construction, machinery, transportation, ships, and electricity. Therefore, due to different application scenarios, it is often necessary to cut it into specified sizes.

[0003] After retrieval, a utility model with the Chinese patent publication number CN217144131U discloses a material pressing mechanism for cutting rubber and plastic thermal insulation cotton, including a gantry, a placement plate, a guide post, a pressing plate, and a winch. A guide groove is formed through the top of the gantry, a guide post is sleeved in the guide groove, the bottom of the guide post is connected with a pressing plate, a fourth through hole is formed through one side of the top of the guide post, a mounting plate is welded to one side of the bottom of the gantry, and a winch is installed on the top of the mounting plate through bolts.

[0004] The above device squeezes and fixes the material by the self-weight of the pressing plate. When in use, in order to ensure production efficiency, multiple layers of thermal insulation cotton are often stacked together for operation. If the material is narrow, when it is under pressure, the problem of the wide surface of the stacked material being sunken inward is likely to occur, as shown below Figure 5 shown, which may cause other materials not to be cut, or even the materials to be scattered directly. Summary of the Invention

[0005] The purpose of the utility model is to provide a material pressing mechanism for cutting rubber and plastic thermal insulation cotton to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A material pressing mechanism for cutting rubber and plastic thermal insulation cotton, including a workbench. One side of the outer wall of the top of the workbench is rotatably connected with a placement plate through a bearing. Two support components are installed on the top of the placement plate, and the two support components are symmetrically arranged. The other side of the outer wall of the top of the workbench is fixedly connected with a support plate. A cylinder is fixedly installed on the outer wall of the top of the support plate. The output end of the cylinder is fixedly connected with a horizontally arranged pressing plate. Both support components can be located directly below the support plate. The support component includes an installation groove formed inside the placement plate. The same lead screw is rotatably connected to the inner walls of both sides of the installation groove. A support back plate is threadedly sleeved on the outside of the lead screw. Two horizontally arranged limiting rods are fixedly connected to the inner walls of both sides of the installation groove. The support back plate is slidably sleeved on the outside of the two limiting rods.

[0007] As a further preference of the present technical solution, two limiting grooves are provided on the outer wall of one side of the support backboard, and a side support frame is slidably inserted into each of the two limiting grooves. A plurality of positioning slots are provided on the outer wall of the top of the two side support frames at equal intervals. A bolt is slidably inserted into the middle of the outer wall of the top of the support backboard, and the bolt can pass through a plurality of positioning slots.

[0008] It can support and limit the positions on both sides and the back of the stacked heat insulation cotton, thus ensuring that it will not be indented inward due to external forces during the processing work, and it is also convenient for its work. By driving the screw rod connected thereto to rotate through the handle, the support backboard restricted by the two limiting rods can only move horizontally. Therefore, the screw rod will drive the support backboard to translate, and then pull the two side support frames outward or push them inward. When they can just fit with both sides of the heat insulation cotton, then insert the bolt downward from the support backboard, and it will be inserted into the two corresponding positioning slots of the two side support frames. Thus, the positions of the two side support frames will be restricted. Under the restriction of the support backboard and the two side support frames, the stacked heat insulation cotton will not change randomly, and it can also be used as a reference for placement.

[0009] As a further preference of the present technical solution, a position-changing component is installed at the output end of the air cylinder, and the position-changing component forms a transmission cooperation with the placement plate.

[0010] As a further preference of the present technical solution, the position-changing component includes a moving rod fixedly sleeved at the bottom of the output end of the air cylinder. One end of the moving rod is fixedly connected with a vertically arranged rack. Two mounting seats are fixedly connected to the outer wall of the bottom of the workbench. The two mounting seats are rotatably connected with the same gear rod through bearings. The rack meshes with the gear end of the gear rod, and the number of convex teeth of the rack is half of the number of convex teeth of the gear rod. One end of the gear rod is coaxially fixed with a bevel gear one. A bevel gear two is fixedly sleeved on the circumferential outer wall of the rotating shaft of the placement plate. The bevel gear one meshes with the bevel gear two.

[0011] As a further preference of the present technical solution, a positioning rod is slidably inserted into a corner of the placement plate. A positioning groove adapted to the positioning rod is provided at a corner of the outer wall of the top. After the positioning rod is inserted into the positioning groove, the workbench will be parallel to the placement plate. A spring is sleeved outside the positioning rod, and the two ends of the spring are respectively fixedly connected with one end of the positioning rod and the placement plate.

[0012] The air cylinder drives the rack to move downward through the moving rod. The rack drives the gear rod to rotate inside the two mounting seats through meshing. Furthermore, the first bevel gear will also be driven by the gear rod to rotate half a circle. The first bevel gear drives the second bevel gear to rotate half a circle through meshing. Subsequently, the material placing plate will drive the material to move to the bottom position of the support plate. Then, when the positioning rod that is pushed up by the workbench moves to the positioning hole, the spring will drive the positioning rod into the positioning hole, thereby ensuring that the position of the material will not shift and facilitating the subsequent reset work of the rack. That is, when the rack is driven to move upward, the machined material will be driven by the material placing plate to move outside the workbench, so that the material will not approach the output component during the feeding and taking processes, ensuring that the device is safer.

[0013] As a further preferred embodiment of this technical solution, a vertically arranged stabilizing rod is fixedly connected to the outer wall of one side of the support plate, and the rack is slidably sleeved outside the stabilizing rod.

[0014] As a further preferred embodiment of this technical solution, the lead angle of the thread of the external thread of the screw rod is less than the equivalent friction angle.

[0015] The utility model provides a material pressing mechanism for cutting rubber and plastic insulation cotton, having the following beneficial effects:

[0016] (1) By setting the support assembly in the utility model, the two side positions and the back position of the stacked insulation cotton can be supported and restricted, thereby ensuring that it will not be indented inward due to external force during the processing work and facilitating the progress of its work. By driving the screw rod connected thereto to rotate through the handle, the support back plate restricted by the two limiting rods can only move horizontally. Therefore, the screw rod will drive the support back plate to translate, and then pull the two side support frames outward or push them inward. When they can just fit with the two sides of the insulation cotton, insert the bolt downward from the support back plate, and it will be inserted into the two corresponding positioning slots of the two side support frames. Thus, the positions of the two side support frames will be restricted. Under the restriction of the support back plate and the two side support frames, the stacked insulation cotton will not change randomly, and they can also be used as references for easy placement.

[0017] (2) The utility model ensures the safety of the device by setting a position-changing component. The air cylinder drives the rack to move downward through a moving rod. The rack drives the gear rod to rotate inside two mounting seats through meshing. Then, the first bevel gear will also be driven by the gear rod to rotate half a circle. The first bevel gear drives the second bevel gear to rotate half a circle through meshing. Subsequently, the material placing plate drives the material to move to the bottom position of the support plate. Then, when the positioning rod that is pushed up by the workbench moves to the positioning hole, the spring drives the positioning rod into the positioning hole, ensuring that the position of the material does not shift and facilitating the subsequent reset work of the rack. That is, when the rack is driven to move upward, the machined material will be driven by the material placing plate to move outside the workbench, so that the material will not approach the output component during the feeding and taking processes, ensuring the device is safer.

Specific Embodiments

[0024] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model.

[0025] The utility model provides the following technical solutions: As Figure 2 , Figure 3 and Figure 5As shown in the figure, in this embodiment, a material pressing mechanism for cutting rubber and plastic insulation cotton includes a workbench 1. One side of the outer wall of the top of the workbench 1 is rotatably connected to a storage plate 607 through a bearing. Two support components 5 are installed on the top of the storage plate 607, and the two support components 5 are symmetrically arranged. The other side of the outer wall of the top of the workbench 1 is fixedly connected to a support plate 2. A cylinder 3 is fixedly installed on the outer wall of the top of the support plate 2. The output end of the cylinder 3 is fixedly connected to a horizontally arranged pressing plate. When the cylinder 3 on the top of the support plate 2 is started, the pressing plate at the bottom of its output end is driven to move synchronously. Finally, when the pressing plate continues to move, the stacked materials will be pressed tightly. Both support components 5 can be located directly below the support plate 2. The support component 5 includes an installation groove opened inside the storage plate 607. The same lead screw 501 is rotatably connected to the inner walls on both sides of the installation groove. A support back plate 503 is sleeved on the outside of the lead screw 501 in a threaded manner. Two horizontally arranged limiting rods 502 are fixedly connected to the inner walls on both sides of the installation groove. The support back plate 503 is slidably sleeved on the outside of the two limiting rods 502.

[0026] Two limiting grooves are opened on one side outer wall of the support back plate 503, and a side support frame 504 is slidably inserted into each of the two limiting grooves. A plurality of equally spaced positioning slots 505 are opened on the outer walls of the tops of the two side support frames 504. A bolt 506 is slidably inserted into the middle of the outer wall of the top of the support back plate 503, and the bolt 506 can pass through a plurality of positioning slots 505.

[0027] By driving the lead screw 501 connected thereto to rotate through a handle, the support back plate 503 restricted by the two limiting rods 502 can only move horizontally. Therefore, the lead screw 501 will drive the support back plate 503 to translate, and then pull the two side support frames 504 outward or push them inward. When the two side support frames 504 can just fit the two sides of the insulation cotton, then insert the bolt 506 downward from the support back plate 503, and it will be inserted into two corresponding positioning slots 505 of the two side support frames 504. Thus, the positions of the two side support frames 504 will be restricted. Under the restriction of the support back plate 503 and the two side support frames 504, the stacked insulation cotton will not change randomly, and the three can also be used as a reference for easy placement.

[0028] As Figure 2 and Figure 4 As shown in the figure, a conversion component 6 is installed at the output end of the cylinder 3, and the conversion component 6 forms a transmission cooperation with the storage plate 607.

[0029] The commutation component 6 includes a moving rod 601 fixedly sleeved at the bottom of the output end of the air cylinder 3. One end of the moving rod 601 is fixedly connected with a vertically arranged rack 602. Two mounting seats 603 are fixedly connected to the outer wall of the bottom of the workbench 1. The two mounting seats 603 are rotatably connected by a bearing to the same gear rod 604. The rack 602 meshes with the gear end of the gear rod 604, and the number of convex teeth of the rack 602 is half of the number of convex teeth of the gear rod 604. One end of the gear rod 604 is coaxially fixed with a first bevel gear 605. A second bevel gear 606 is fixedly sleeved on the circumferential outer wall of the rotating shaft of the placing plate 607. The first bevel gear 605 meshes with the second bevel gear 606.

[0030] A positioning rod 608 is slidably inserted into a corner of the placing plate 607. A positioning groove adapted to the positioning rod 608 is provided at a corner of the outer wall of the top. When the positioning rod 608 is inserted into the positioning groove, the workbench 1 will be parallel to the placing plate 607. A spring 609 is sleeved outside the positioning rod 608. The two ends of the spring 609 are respectively fixedly connected with one end of the positioning rod 608 and the placing plate 607.

[0031] The air cylinder 3 drives the rack 602 to move downward through the moving rod 601. The rack 602 drives the gear rod 604 to rotate inside the two mounting seats 603 through meshing. Furthermore, the first bevel gear 605 will also be driven by the gear rod 604 to rotate half a circle. The first bevel gear 605 drives the second bevel gear 606 to rotate half a circle through meshing. Subsequently, the placing plate 607 will drive the material to move to the bottom position of the support plate 2. Then, when the positioning rod 608 that is pushed up by the workbench 1 moves to the positioning hole, the spring 609 will drive the positioning rod 608 to enter the positioning hole, so as to ensure that the position of the material will not shift, and it is also convenient for the subsequent reset work of the rack 602. That is, when the rack 602 is driven to move upward, the cut material will be driven by the placing plate 607 to move outside the workbench 1, so that the material will not approach the output component during the feeding and taking processes, ensuring that the device is safer.

[0032] As Figure 2 shown, a vertically arranged stabilizing rod 4 is fixedly connected to the outer wall of one side of the support plate 2. The rack 602 is slidably sleeved outside the stabilizing rod 4. Under the action of the stabilizing rod 4, the state of the rack 602 can be ensured to be stable enough, so that the subsequent transmission can proceed smoothly.

[0033] As Figure 1 and Figure 3 shown, the lead angle of the thread of the external thread of the lead screw 501 is smaller than the equivalent friction angle, so that it has a self-locking property, and further ensures that the support back plate 503 has good enough abutting performance.

[0034] The present utility model provides a material pressing mechanism for cutting rubber and plastic insulation cotton. The specific working principle is as follows:

[0035] When the device is working, first adjust the support assembly 5 according to the size of the thermal insulation cotton. Drive the lead screw 501 connected to it to rotate through the handle. The support back plate 503 restricted by the two limit rods 502 can only move horizontally. Therefore, the lead screw 501 will drive the support back plate 503 to translate. Then pull the two side support frames 504 outwards or push them inwards. When they can just fit the two sides of the thermal insulation cotton, insert the bolt 506 downwards from the support back plate 503, and it will insert into the two positioning slots 505 corresponding to the two side support frames 504. Thus, the positions of the two side support frames 504 will be restricted. Restricted by the support back plate 503 and the two side support frames 504, the stacked thermal insulation cotton will not change randomly, and it can also be used as a reference for placing. Then start the cylinder 3 on the top of the support plate 2, and the pressure plate at the bottom of its output end will be driven to move synchronously. The cylinder 3 drives the rack 602 to translate downwards through the moving rod 601. The rack 602 drives the gear rod 604 to rotate inside the two mounting seats 603 through meshing. Furthermore, the first bevel gear 605 will also be driven by the gear rod 604 to rotate half a circle. The first bevel gear 605 drives the second bevel gear 606 to rotate half a circle through meshing. Subsequently, the placing plate 607 will drive the material to move to the bottom position of the support plate 2. Then when the positioning rod 608 that moves upward against the workbench 1 moves to the positioning hole, the spring 609 will drive the positioning rod 608 into the positioning hole, thus ensuring that the position of the material will not shift and facilitating the subsequent reset work of the rack 602. That is, when the rack 602 is driven to move upward, the cut material will be driven by the placing plate 607 to move outside the workbench 1, so that the material will not approach the output component during the feeding and taking processes, ensuring the safety of the device. Finally, the pressure plate continues to move, and the stacked materials will be pressed tightly, and then the cutting work can be carried out.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
