Description

Technical Field

[0001] The utility model relates to the technical field of expandable polystyrene sheet cutting, in particular to an expandable polystyrene sheet cutting device. Background Technique

[0002] Expandable polystyrene (referred to as EPS) is one of the world's three major plastic products. It has the characteristics of light weight, good heat insulation, water resistance, and low price. It can be widely used in product packaging, thermal insulation, color steel plate houses, decoration, and the production of industrial product models, pipeline insulation and other industrial products. At present, the cutting of expandable polystyrene sheets uses resistance wire heating cutting.

[0003] However, the control structure of the guide rail slider in the existing cutting device is complex and has a high failure rate.

[0004] As disclosed in a Chinese patent CN204382397U for an expandable polystyrene sheet cutting machine, when in use, low-voltage alternating current is applied to the surface thread conductive columns, and the cutting resistance wire wound around the two surface thread conductive columns generates heat, and reciprocating linear motion is coordinated with the horizontal walking drive mechanism to achieve cutting. The guide rails on both sides of the longitudinal table play a guiding role, so that the movement of the cutting wire can be ensured to be stable, and the cut sheet can be made uniform and not deformed. The surface thread conductive columns on the middle part of the column of the utility model can play a role in fixing and positioning the cutting resistance wire. Because the threads are obliquely designed, there is a distance between adjacent threads, and they can rotate relative to the upper and lower insulating supports. In this way, when there are different thickness requirements for single-piece or small-batch production, the cutting resistance wire wound around the threads of the two surface thread conductive columns can rotate with the rotation of the two surface thread conductive columns to complete continuous adjustment of the up and down positions. The quality of the cut sheet is significantly improved. And in one production process, sheet products of multiple specifications can be processed at the same time. Therefore, the utility model can make the cutting of expandable polystyrene sheets of multiple varieties and specifications easy to adjust and has a simple structure.

[0005] However, the position of the cutting resistance wire on this cutting machine cannot be adjusted, so it is not convenient to adjust according to the cutting position of the expandable polystyrene board.

[0006] Therefore, we urgently need to provide an expandable polystyrene sheet cutting device with an adjustment function. Content of the Utility Model

[0007] The purpose of the utility model is to provide an expandable polystyrene sheet cutting device to solve the problem that the position of the cutting resistance wire on the cutting machine proposed in the above background technique cannot be adjusted, so it is not convenient to adjust according to the cutting position of the expandable polystyrene board.

[0008] To achieve the above object, the present utility model provides the following technical solutions: A cutting device for expandable polystyrene sheets, comprising an upper cross beam and columns. The columns are fixedly connected to the front and rear sides of the upper cross beam. At the lower left and right ends of the columns, rollers are fixedly connected. The lower ends of the rollers are in rolling connection with guide rails. The outer ends of the upper cross beam and the columns are connected with a cutting mechanism. The cutting mechanism includes a cutting unit and a heat dissipation unit. The cutting unit is arranged at the outer end of the column, and the heat dissipation unit is arranged at the outer end of the upper cross beam.

[0009] The cutting unit includes a first threaded rod, a first handle, a bearing, a moving plate, an insulating rod, a surface-threaded conductive column, and a cutting resistance wire. The first threaded rod is connected to the upper end inside the column. The first handle is fixedly connected to the upper end of the first threaded rod. The bearing is fixedly connected to the outer side of the lower end of the first threaded rod. The moving plate is fixedly connected to the outer end of the bearing. The surface-threaded conductive column is arranged below the moving plate. The insulating rod is fixedly connected to the upper and lower ends of the surface-threaded conductive column. The cutting resistance wire is fixedly connected to the outer end of the surface-threaded conductive column.

[0010] Further improvement lies in that a through groove is provided inside the column. A first threaded hole is opened at the position inside the column above the through groove. The outer side of the first threaded rod is in threaded connection with the inner side of the first threaded hole. Thus, when the first handle is rotated to drive the first threaded rod to rotate in the first threaded hole, the first threaded rod can move relative to the column while rotating.

[0011] Further improvement lies in that the left and right sides of the moving plate are in sliding connection with the inner side of the through groove. The upper side of the insulating rod at the upper end of the surface-threaded conductive column is fixedly connected to the lower side of the moving plate. Thus, when the first handle is rotated to drive the first threaded rod to rotate and move, and the lower moving plate slides along the inner side of the through groove, the lower surface-threaded conductive column and the cutting resistance wire can be driven to move together.

[0012] Further improvement lies in that the heat dissipation unit includes a connecting plate, a second threaded rod, a second handle, a motor, a rotating rod, and an impeller. The connecting plate is fixedly connected to the middle position on the left side of the upper cross beam. The second threaded rod is connected to the front of the left end inside the connecting plate. The second handle is fixedly connected to the upper end of the second threaded rod. The motor is connected to the left end inside the connecting plate. The rotating rod is fixedly connected to the upper front and rear sides of the motor. The impeller is fixedly connected to the outer side of the lower end of the output shaft of the motor.

[0013] A further improvement lies in that a groove is formed in the middle position at the left end inside the connecting plate, and rotating holes are formed in the middle positions at the front and rear ends of the groove inside the connecting plate. The front and rear sides at the upper end of the motor are slidably connected to the front and rear ends inside the groove, and the outer side of the rotating rod is rotatably connected to the inner side of the rotating hole. Thus, when the rotating rod rotates in the rotating hole, the motor can be driven to rotate together, and then the angle of the impeller can be driven to rotate.

[0014] A further improvement lies in that a second threaded hole is formed in the position in front of the upper end of the rotating hole inside the connecting plate. The outer side of the second threaded rod is threadedly connected to the inner side of the second threaded hole, and the lower end of the second threaded rod abuts against the upper end of the outer side of the rotating rod at the front end of the motor. Thus, after adjusting the angle of the impeller by rotating the rotating rod, while rotating the second handle to drive the second threaded rod to rotate and move downward until the second threaded rod moves to contact the upper end of the outer side of the rotating rod, the rotating rod can be squeezed and fixed to the inner side of the rotating hole.

[0015] A further improvement lies in that a third threaded hole is formed in the front of the lower end of the output shaft of the motor, and a circular hole is formed in the front end inside the impeller. Thus, by passing a bolt through the circular hole and then threadedly connecting it into the third threaded hole, the impeller can be fixed to the outer side of the output shaft of the motor.

[0016] In summary, the present application discloses a cutting device for expandable polystyrene plates.

[0017] In this technical solution, when driving the first threaded rod to rotate and move by rotating the first handle, and driving the lower moving plate to slide along the inner side of the through groove, the surface wire conductive column and the cutting resistance wire at the lower end can be driven to move together, so as to facilitate the adjustment of the cutting position of the cutting resistance wire.

[0018] Furthermore, after adjusting the angle of the impeller by rotating the rotating rod, while rotating the second handle to drive the second threaded rod to rotate and move downward until the second threaded rod moves to contact the upper end of the outer side of the rotating rod, the rotating rod can be squeezed and fixed to the inner side of the rotating hole, so that the impeller can be adjusted to a suitable angle and then fixed, and thus the cutting resistance wire can be cooled and dissipated heat in time, preventing it from being damaged due to excessive temperature during long-term operation.

Specific implementation mode

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1 - 4 , the present utility model provides a technical solution:

[0026] Embodiment 1:

[0027] An expandable polystyrene sheet cutting device includes an upper crossbeam 1 and columns 2. The columns 2 are fixedly connected to the front and rear sides of the upper crossbeam 1. The left and right ends of the lower sides of the columns 2 are fixedly connected with rollers 3. The lower ends of the rollers 3 are in rolling connection with a guide rail 4. A cutting mechanism is connected to the outer ends of the upper crossbeam 1 and the columns 2. The cutting mechanism includes a cutting unit and a heat dissipation unit. The cutting unit is arranged at the outer end of the column 2, and the heat dissipation unit is arranged at the outer end of the upper crossbeam 1.

[0028] The cutting unit includes a first threaded rod 501, a first handle 502, a bearing 503, a moving plate 504, an insulating rod 505, a surface-threaded conductive column 506, and a cutting resistance wire 507. The first threaded rod 501 is connected to the upper end inside the column 2. The first handle 502 is fixedly connected to the upper end of the first threaded rod 501. A through groove is arranged inside the column 2. A first threaded hole is opened at the position above the through groove inside the column 2. The outer side of the first threaded rod 501 is threadedly connected to the inner side of the first threaded hole. Thus, when the first handle 502 is rotated to drive the first threaded rod 501 to rotate in the first threaded hole, the first threaded rod 501 can move relative to the column 2 while rotating.

[0029] The bearing 503 is fixedly connected to the outer side of the lower end of the first threaded rod 501. The moving plate 504 is fixedly connected to the outer end of the bearing 503. The surface-threaded conductive column 506 is arranged below the moving plate 504. The insulating rod 505 is fixedly connected to the upper and lower ends of the surface-threaded conductive column 506. The cutting resistance wire 507 is fixedly connected to the outer end of the surface-threaded conductive column 506. The left and right sides of the moving plate 504 are slidably connected to the inner side of the through groove. The upper side of the insulating rod 505 at the upper end of the surface-threaded conductive column 506 is fixedly connected to the lower side of the moving plate 504. Thus, when the first handle 502 is rotated to drive the first threaded rod 501 to rotate and move at the same time, and the lower moving plate 504 is driven to slide along the inner side of the through groove, the lower surface-threaded conductive column 506 and the cutting resistance wire 507 can be driven to move together, so as to facilitate the adjustment of the cutting position of the cutting resistance wire 507.

[0030] Embodiment Two:

[0031] On the basis of Embodiment One: The heat dissipation unit includes a connecting plate 601, a second threaded rod 602, a second handle 603, a motor 604, a rotating rod 605 and an impeller 606. The connecting plate 601 is fixedly connected to the middle position on the left side of the upper cross beam 1. The second threaded rod 602 is connected to the front of the inner left end of the connecting plate 601. The second handle 603 is fixedly connected to the upper end of the second threaded rod 602. The motor 604 is connected to the inner left end of the connecting plate 601. The rotating rod 605 is fixedly connected to the upper ends on the front and rear sides of the motor 604. The impeller 606 is fixedly connected to the outer side of the lower end of the output shaft of the motor 604. A groove is opened at the middle position of the inner left end of the connecting plate 601. Through holes are opened at the middle positions of the front and rear ends of the connecting plate 601 inside the groove. The front and rear sides of the upper end of the motor 604 are slidably connected to the front and rear ends of the inner side of the groove. The outer side of the rotating rod 605 is rotatably connected to the inner side of the through hole. Thus, when the rotating rod 605 rotates in the through hole, the motor 604 can be driven to rotate together, so that the angle of the impeller 606 can be rotated, so as to facilitate the adjustment of the blowing angle of the impeller 606 according to the position of the cutting resistance wire 507.

[0032] A second threaded hole is opened at the position in front of the upper end of the through hole inside the connecting plate 601. The outer side of the second threaded rod 602 is threadedly connected to the inner side of the second threaded hole. The lower end of the second threaded rod 602 abuts against the outer side of the upper end of the rotating rod 605 at the front end of the motor 604. Thus, after the angle of the impeller 606 is adjusted by rotating the rotating rod 605, by rotating the second handle 603 to drive the second threaded rod 602 to rotate and move downward at the same time, until the second threaded rod 602 moves to contact the outer side of the upper end of the rotating rod 605, the rotating rod 605 can be squeezed and fixed to the inner side of the through hole, so that the impeller 606 can be adjusted to a suitable angle and fixed.

[0034] On the basis of the first embodiment: There is a third threaded hole at the front of the lower end of the output shaft of the motor 604, and a round hole is provided at the inner front end of the impeller 606. Thus, by passing a bolt through the round hole and then threadedly connecting it into the third threaded hole, the impeller 606 can be fixed to the outside of the output shaft of the motor 604. Therefore, after the impeller 606 has been used for a long time, it can be disassembled from the round hole by rotating the bolt, and then the impeller 606 can be removed from the outer end of the output shaft of the motor 604, and then the impeller 606 can be cleaned.

[0035] Working principle: When in use, first rotate the first handle 502 to drive the first threaded rod 501 to rotate, while driving the moving plate 504 to move along the inner side of the through groove, driving the surface thread conductive column 506 and the cutting resistance wire 507 at the lower end to move to a suitable position, and then rotate the motor 604 so that the rotating rod 605 rotates in the rotating hole. At the same time, when the impeller 606 rotates to make the direction of the generated air flow face the cutting resistance wire 507, place the expandable polystyrene sheet to be cut on the guide rail 4, and then drive the roller 3 to roll on the guide rail 4, driving the cutting resistance wire 507 at the upper end to move towards the expandable polystyrene sheet for cutting.
