Description

Technical Field

[0001] This utility model relates to the technical field of geomembrane production equipment, and in particular to an adjustable trimming device for geomembrane production. Background Technology

[0002] In geomembrane production, after the membrane material has cooled and shaped, excess and uneven sides need to be removed. Existing trimming devices have two main problems: First, when adjusting the cutting position, some devices use direct lateral drive, which causes the cutting edge to rub against the supporting platform continuously, resulting in blunting of the cutting edge and scratches on the platform; Second, the disassembly process of the cutting discs is cumbersome, affecting maintenance efficiency. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as easy damage to the blade and cumbersome disassembly, by proposing an adjustable trimming device for geomembrane production.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An adjustable trimming device for geomembrane production includes a base, on the top of which a support platform is fixedly installed.

[0006] Two guide rollers are mounted on both sides of the top of the base via bearings, and the support platform is located above the two guide rollers;

[0007] A gantry frame is fixedly installed on a base, and a support platform is located below the gantry frame. The gantry frame is internally fitted with a bidirectional threaded rod and a limit rod is fixedly installed.

[0008] Two movable seats are respectively threaded onto both sides of the outer wall of the bidirectional threaded rod and slidably connected to the limiting rod;

[0009] The lifting seat is slidably connected to the inside of the movable seat via a vertical slide rail;

[0010] Cut circular pieces and install them on the outer wall of the lifting base via bearings;

[0011] The motor is installed on the top inner wall of the lifting platform, and its output shaft is connected to the rotating shaft of the cutting disc through a sprocket and chain.

[0012] The L-shaped frame is slidably connected to the limiting shaft fixed on the back of the gantry frame, and threadedly sleeved on the threaded shaft rotatably installed on the back of the gantry frame.

[0013] The inclined guide frame is fixedly installed on the top of the lifting seat, and its inclined surface matches the horizontal part of the L-shaped frame;

[0014] When the L-shaped frame moves, its horizontal portion abuts against the inclined surface of the inclined guide frame, pushing the lifting seat upward and causing the cutting disc to detach from the support platform, thus avoiding friction damage between the cutting edge and the support platform during lateral adjustment.

[0015] In one possible design, a limiting plate is fixedly installed on the side wall of the movable seat;

[0016] The end of the rotating shaft of the cutting disc is threaded with a limiting cap, and the limiting cap cooperates with the limiting plate;

[0017] When the lifting seat moves upward, the limit cap is released from the constraint of the limit plate, making it easier to disassemble and cut the disc.

[0018] In one possible design, a telescopic rod is installed between the top inner wall of the movable seat and the top of the lifting seat, and a compression spring is provided inside the telescopic rod;

[0019] The compression spring provides the restoring force, causing the lifting seat to move downwards when the L-shaped frame is reset.

[0020] One possible design also includes:

[0021] The limiting cross seat is fixedly installed inside the gantry frame, and its side wall has multiple through holes;

[0022] The insertion rod is elastically connected to the movable seat by a tension spring, and one end of it can be inserted into the through hole of the limiting cross seat;

[0023] The abutment is fixedly installed on the side wall of the vertical section of the L-shaped frame;

[0024] When the L-shaped frame moves, the abutment rod inserts into the through hole of the limiting cross seat and pushes the insert rod out, releasing the limiting of the moving seat.

[0025] In one possible design, the sidewall of the movable seat is fitted with a protective shell to shield the sprockets and chains.

[0026] The outer wall of the bidirectional threaded rod is fitted with a bellows-shaped protective cover for sealing and protection.

[0027] In one possible design, a rotating plate is mounted on the side of the limiting plate via a bearing;

[0028] Among them, the rotating plate reduces friction when the limit cap rotates.

[0029] In one possible design, the cutting disc is detachably mounted on its shaft;

[0030] When the lifting platform moves upward, the cutting disc can be easily removed and replaced.

[0031] In this application, during actual use, the trimming device is installed between the conveying devices after the geomembrane has cooled. The geomembrane passes sequentially under the guide roller, over the top of the supporting platform, and then under another guide roller. A drive motor rotates the sprocket chain, which in turn drives the cutting disc to rotate, thereby cutting off the excess and uneven sides of the membrane. (See attached document.) Figure 1 If the membrane is conveyed from one side of the L-shaped frame to the other side of the moving seat, the motor will drive counterclockwise.

[0032] When adjusting the cutting edge position of the membrane, the operator first drives the threaded shaft to rotate, thereby controlling the L-shaped frame to move to one side of the moving seat. As the L-shaped frame moves, its horizontal end will abut against the inclined surface of the inclined guide frame, pushing the lifting seat upwards. This causes the cutting disc to disengage from the support platform, preventing damage caused by the cutting surface of the cutting disc directly contacting the surface of the support platform during lateral adjustment. Simultaneously, as the lifting seat moves upwards, the limit cap will disengage from the limit plate, allowing it to be unscrewed and released from the constraint on the cutting disc, making it easy for the operator to remove and replace it. Furthermore, when the L-shaped frame moves laterally, causing the lifting seat to move upwards, the abutment rod on the side wall of the L-shaped frame will... The rod is inserted into the through hole of the limiting horizontal seat, causing it to push the rod to move and disengage from the through hole, thereby releasing the restriction between the moving seat and the limiting horizontal seat. When the lifting seat moves to its highest position, the end of the abutment rod is flush with the side wall of the limiting horizontal seat. Then, the bidirectional threaded rod can be driven to rotate, thereby causing the moving seats on both sides of the outer wall to move in opposite directions, realizing the adjustment of the cutting disc position. After the adjustment is completed, the threaded shaft can be driven to drive the L-shaped frame to reset. At this time, the lifting seat will be reset by gravity and the force of the internal compression spring of the telescopic rod, so that the cutting disc is once again attached to the top of the support platform. The rod will also be reset by the force of the tension spring, so that one end is re-inserted into the through hole, limiting and fixing the moving seat to ensure stability during cutting.

[0033] In this utility model, the adjustable trimming device for geomembrane production can achieve linkage control of lifting and lateral adjustment of the cutting component through the wedge mechanism of the L-shaped frame and the inclined guide frame. When the limit of the moving seat is released, it automatically drives the cutting disc to rise, thereby avoiding frictional damage between the cutting edge and the supporting surface.

[0034] In this utility model, the adjustable trimming device for geomembrane production, through the cooperation of the lifting seat and the limiting plate, can release the restriction of the limiting twist cover when the lifting seat is driven to move upward, so as to facilitate the replacement of the cutting disc.

[0035] In this invention, when the limit of the movable seat used to install the cutting disc is released, the cutting disc can be moved upward to disengage from the bottom support platform, thus avoiding wear and scratches. At the same time, the constraint of the limit cover can be released, making it convenient to replace the cutting disc. Attached Figure Description

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0044] In one embodiment: Reference Figure 1An adjustable trimming device includes: a base 1, a support platform 3 fixed to the top of the base by bolts, guide rollers 2 symmetrically arranged on both sides, a gantry frame 7 fixed above the base 1 by bolts, a bidirectional threaded rod 6 rotatably installed on the side of its crossbeam through bearing seats, limit rods fixed to the inner walls of the two vertical beams, two movable seats 5 respectively threadedly sleeved on the left and right threaded sections of the bidirectional threaded rod 6, and slidably sleeved on the limit rods to form a lateral moving pair, a reduction motor installed on the side wall of the gantry frame 7, the output shaft of which is connected to one end of the bidirectional threaded rod 6, driving the bidirectional threaded rod 6 to rotate by driving the reduction motor, thereby driving the movable seats 5 to perform lateral displacement, thereby driving the corresponding cutting disc 4 to be adjusted.

[0045] refer to Figure 3 Inside the movable seat 5, a lifting seat 13 is slidably connected via a vertical slide rail. A telescopic rod 12 with a compression spring is provided between its top and the top wall of the movable seat. A motor 15 is fixed to the inner wall of the top of the lifting seat by bolts. The output shaft of the motor is connected to the rotating shaft of the cutting disc 4 via a sprocket and chain. The cutting disc 4 is slidably sleeved on the outer wall of the rotating shaft.

[0046] Specifically, the trimming device is installed between the conveying devices after the geomembrane has cooled. The geomembrane passes sequentially under the guide roller 2, over the support platform 3, and then under another guide roller 2. The drive motor 15 rotates the sprocket chain, which in turn drives the cutting disc 4 to rotate, thereby cutting off the excess and uneven sides of the membrane. (See attached diagram.) Figure 1 If the membrane is conveyed from one side of the L-shaped frame 10 to one side of the movable seat 5, the motor 15 will drive counterclockwise.

[0047] refer to Figure 2-4 A threaded shaft 11 is rotatably mounted on the back side of the gantry frame 7 via a bearing seat, and a limit shaft 8 is fixed thereon. The threaded shaft 11 is driven by a geared motor (not shown in the figure). The L-shaped frame 10 is slidably sleeved on the limit shaft, and it has a threaded hole that mates with the threaded shaft. An inclined guide frame 19 is welded to the top of the lifting seat. When the L-shaped frame 10 moves horizontally, its horizontal section end mates with the inclined surface. When the L-shaped frame 10 is driven to move, its horizontal section end will abut against the inclined surface of the inclined guide frame 19, thereby pushing the lifting seat 13 to move upward, so that the cutting disc 4 is separated from the support platform 3, thereby avoiding damage caused by the cutting surface of the cutting disc 4 directly touching the surface of the support platform 3 when it moves laterally.

[0048] The limiting horizontal seat 17 is fixed inside the gantry frame 7 by bolts. Both sides of its side wall are provided with through holes. The through holes are drilled according to the required cutting edge position. The side wall of the movable seat 5 is connected to the insertion rod 16 by a tension spring. The end of the insertion rod can be inserted into the through hole of the limiting horizontal seat 17 to form a positioning. The outer wall of the vertical section of the L-shaped frame is welded with a stop rod 9. The outer diameter of the stop rod is adapted to the through hole size of the limiting horizontal seat.

[0049] Specifically, when it is necessary to adjust the cutting edge position of the film, the operator first drives the threaded shaft 11 to rotate, thereby controlling the movement of the L-shaped frame 10, which pushes the lifting seat 13 to move upward. When the L-shaped frame 10 drives the lifting seat 13 to move upward, the abutment 9 on the side wall of the L-shaped frame 10 will be inserted into the through hole of the limiting horizontal seat 17, which pushes the insertion rod 16 to move, so that the insertion rod 16 disengages from the through hole, thereby releasing the restriction between the moving seat 5 and the limiting horizontal seat 17. When the lifting seat 13 moves to the highest position, the end of the abutment 9 is flush with the side wall of the limiting horizontal seat 17. Then, the bidirectional threaded rod 6 can be driven to rotate, thereby driving the moving seats 5 on both sides of the outer wall to move in opposite directions, realizing the adjustment of the position of the cutting disc 4.

[0050] After adjustment, the threaded shaft 11 can be driven to drive the L-shaped frame 10 to reset. At this time, the lifting seat 13 will be reset by gravity and the force of the internal compression spring of the telescopic rod 12, so that the cutting disc 4 is once again attached to the top of the support platform 3. The insertion rod 16 will also be reset by the force of the tension spring, so that one end is re-inserted into the through hole, and the moving seat 5 is limited and fixed to ensure the stability during cutting.

[0051] This application can be used in the field of geomembrane production equipment, or in other fields applicable to this application.

[0052] In another embodiment: Reference Figure 4 An adjustable trimming device for geomembrane production is applied to the field of geomembrane production equipment. The end of the rotating shaft of the cutting disc 4 is threaded with a limiting cap 18, and the side wall of the movable seat 5 is welded with a limiting plate 14.

[0053] Specifically, when the lifting seat 13 moves upward, the limit cap 18 will be released from the constraint of the limit plate 14, and it can then be unscrewed to release the constraint on the cutting disc 4, making it convenient for the staff to directly remove the cutting disc 4 for replacement.

[0054] A rotating plate is mounted on the side of the limiting plate 14 via a bearing, which reduces the friction between the limiting cover 18 and the limiting plate 14 when the trimming is rotated.

[0055] refer to Figure 6 The outer wall of the bidirectional threaded rod 6 is fitted with a bellows cover 20 to form a fully enclosed protection for the bidirectional threaded rod 6. The side wall of the movable seat 5 is fitted with a protective shell 21 to cover the sprocket and chain and prevent foreign objects from being caught in the chain drive mechanism.

[0056] The telescopic rod 12 can be installed using an existing detachable structure, such as a snap-fit ​​mechanism, which facilitates replacement when the tension spring loses its original restoring force after prolonged use.

[0057] However, as is well known to those skilled in the art, the working principle and wiring method of the motor are conventional methods or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0058] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0059] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
