[0004] However, in the production process, the pressing device provided by the prior art requires that the organic glass of special specifications be pressed by the pressing device and then cut by the cutting device. The process is complicated and the production time is too long. Therefore, a solution is needed to improve this problem. Utility Model Content

[0005] The purpose of the utility model is to provide a pressing and cutting device for the production of organic glass. During the production process, the existing pressing device can only press the organic glass, with a single function, and the subsequent process requires the use of a cutting device, which makes the production time cost too high. The present scheme provides a pressing and cutting device for the production of organic glass, which performs pressing and cutting work simultaneously, thereby reducing the production time cost.

[0006] The utility model provides a pressing and cutting device for producing organic glass, comprising a base and a knife die fixed on the top of the base, wherein the knife die is used for shaping and cutting the organic glass; further comprising a pressing unit which is lifted and arranged on the top of the knife die and a heating unit which is lifted and arranged on the inner side of the knife die, wherein the pressing unit and the heating unit cooperate with each other to press at least two overlapping organic glasses; a reset member for resetting the heating unit is arranged between the heating unit and the base.

[0007] By adopting the above technical solution, the base fixes the cutting die, so that when the plexiglass needs to be pressed and cut, the plexiglass to be pressed and cut is stacked on the heating unit in advance, the heating unit heats the plexiglass and softens it, the pressing unit moves downward toward the heating unit and applies pressure to the plexiglass, so that the stacked plexiglass is pressed, and in addition, as the pressing unit descends, the heating unit moves downward on the base, so that the cutting die is exposed and the plexiglass is shaped and cut; at the same time, when the cutting is completed, the reset member resets the heating unit and moves the cut plexiglass to the outside of the cutting die, which is convenient for taking. The utility model can cut the plexiglass synchronously when pressing it, which can effectively improve work efficiency.

[0008] Optionally, a matching groove matching with the cutting die is provided at the bottom of the pressing unit, and after the cutting die shapes and cuts the organic glass, the top of the cutting die is located in the matching groove.

[0009] By adopting the above technical solution, during the lamination and cutting process, the matching groove at the bottom of the lamination unit can provide a penetration margin for the plexiglass, which is conducive to the knife die to completely cut the plexiglass. In addition, it can play a certain protective role for the lamination unit to avoid rigid contact between the knife die and the lamination unit to cause structural damage.

[0010] Optionally, the base is provided with two parallel positioning frames located at the heating unit, and when the pressing unit is pressed with the heating unit, the side edge of the organic glass is in sliding contact with the inner side of the positioning frame.

[0011] Through the above technical solution, when the plexiglass to be pressed and cut is placed on the heating unit, the two side edges of the plexiglass respectively contact the positioning frame, so that the plexiglass can be positioned; in addition, the positioning frame can play a positioning role for the plexiglass during the pressing process, thereby avoiding the displacement and dislocation of the plexiglass during the pressing process, thereby improving the cutting effect.

[0012] Optionally, the pressing unit is provided with a guide column facing the positioning frame, and the positioning frame is provided with a guide hole which is plugged and matched with the guide column.

[0013] By adopting the above technical solution, when the pressing unit is lifted and moved on the positioning frame, the guide hole of the positioning frame is plugged into and matched with the guide column of the pressing unit, so that the pressing unit corresponds to the positioning frame, which can effectively improve the lifting stability of the pressing unit.

[0014] Optionally, a discharging mechanism is provided between the pressing unit and the heating unit, and the discharging mechanism is located between the two positioning frames, and the discharging mechanism is used to push the plexiglass out of the heating unit in a direction away from the positioning frames; when the pressing unit and the heating unit are pressed, the side edge of the plexiglass slides in contact with the discharging mechanism.

[0015] Through the above technical scheme, when the pressing unit presses the plexiglass, the side edge of the plexiglass slides in contact with the discharging mechanism, so that the discharging mechanism plays a role in positioning the plexiglass. In addition, the pressing unit also slides in contact with the side wall of the discharging mechanism during the descending process; when the plexiglass completes the pressing and cutting operation, the discharging mechanism pushes the plexiglass out of the heating unit, thereby effectively improving the working efficiency of the overall device.

[0016] Optionally, the discharging mechanism includes a pushing plate and a pushing member for displacing the pushing plate, the pushing plate is located between the two positioning frames, and when the heating unit is reset, the pushing plate is used to push the organic glass out.

[0017] Through the above technical scheme, when the pressing unit presses the plexiglass, the side of the plexiglass and the pressing unit are in sliding contact with the pushing plate. At the same time, when the pressing and cutting operation is completed, the heating unit is reset to make one side of the plexiglass contact with the pushing plate, so that the pushing member outputs power to displace the pushing plate, and then pushes the plexiglass out, making the overall operation more automated and avoiding burns caused by manual pushing.

[0018] Optionally, before lamination begins, the push plate contacts the positioning frame and positions the unlaminated organic glass.

[0019] Through the above technical solution, before the organic glass is pressed together, the two sides of the push plate are in contact with the inner side surfaces of the two bosses on the positioning frame, and the organic glass is respectively contacted with the push plate and the inner surface of the two bosses on the positioning frame to position the organic glass, thereby ensuring that there is a maximum pressing and cutting area between the two pieces of organic glass, thereby avoiding waste of materials.

[0020] Optionally, the base is provided with a discharging platform along the direction in which the discharging mechanism pushes the organic glass, and the discharging platform is used for temporarily storing the organic glass.

[0022] Optionally, a separation port is provided on the discharging table, and the separation port is used to separate the cut organic glass.

[0023] Through the above technical solution, when the pressed and cut organic glass is pushed out to the discharging table, a separation port is provided on the discharging table, so that the pushed organic glass falls into the separation port, and the materials required for subsequent production are quickly stored in a centralized manner.

[0024] Optionally, the separation opening is adapted to the shape of the cutting die, and the opening area of ​​the separation opening is greater than or equal to the cutting area of ​​the cutting die.

[0030] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the utility model belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0031] See also Figure 1 The utility model provides a pressing and cutting device for producing organic glass, comprising a table-type base 10 and a knife die 15 fixed on the top of the base 10, wherein the top of the knife die 15 is a cutting end, and shapes and cuts the organic glass. In fact, the table-type design of the base 10 can be better placed on the production table, and can also be integrated into the organic glass production line.

[0032] In some embodiments, the cutting die 15 is fixed to the top of the base 10 by bolts, thereby improving the position stability of the cutting die 15 on the base 10, and the cutting die 15 that has reached its working limit can be replaced by dismantling the bolts. In addition, the shape of the cutting die 15 is adapted to the shape of the organic glass to be cut, that is, different cutting dies 15 can be replaced to adapt to different organic glass cutting conditions.

[0033] In some embodiments, the cutting die 15 is fixed to the top of the base 10 by welding, which can greatly improve the position stability of the cutting die 15 when performing organic glass cutting.

[0034] See also Figure 1 The base 10 also has a pressing unit that is lifted and lowered on the top of the cutting die 15, and a heating unit that is lifted and lowered inside the cutting die 15. When the plexiglass needs to be pressed and cut, at least two pieces of plexiglass are stacked on the top of the cutting die 15, the heating unit heats and softens the plexiglass, the pressing unit and the heating unit press the plexiglass, and the cutting die 15 cuts the plexiglass at the same time.

[0035] In some embodiments, the pressing unit includes an upper fixing seat 30 and an upper lifting member driving the upper fixing seat 30 to move up and down, and the side of the upper fixing seat 30 facing the die cutter 15 is a pressing plane. In fact, during the pressing operation, the pressing plane is in contact with the organic glass to be pressed, thereby improving the force uniformity of the organic glass. Specifically, the lifting member is an electric telescopic rod 24.

[0036] In some embodiments, a matching groove that matches with the cutting die 15 is opened at the bottom of the upper fixing seat 30. After the cutting die 15 shapes and cuts the organic glass, the top of the cutting die 15 is located in the matching groove.

[0037] In some embodiments, the cutting die 15 needs to be completely closed to ensure that the cut material is completely separated from the waste material.

[0038] In some embodiments, the shape of the matching groove corresponds to the cutting die 15. The matching groove can have a variety of shapes, in which the cross-section is rectangular or the same shape as the cutting die 15, and the matching groove must avoid the tip part of the cutting die 15 to avoid destroying the cutting stability of the cutting die 15.

[0039] In some embodiments, an electric heating plate A 32 is embedded in the upper fixing seat 30, and the upper fixing seat 30 is heated by the electric heating plate A 32, thereby cooperating with the heating unit to heat the organic glass to 80-120°C to soften it, thereby improving the pressing and molding effect.

[0040] In some embodiments, the upper fixing seat 30 is made of metal or other heat-conductive rigid materials.

[0041] In fact, when the heating unit is lifted and arranged in the cutting die 15, the side wall of the heating unit is in sliding contact with the inner wall of the cutting die 15, thereby improving the lifting stability of the heating unit during the pressing process.

[0042] In some embodiments, the heating unit includes a placement plate 16 and a reset mechanism that drives the placement plate 16 to move up and down, and the side of the placement plate 16 facing the pressing unit is a placement plane, and the heating unit also includes an electric heating plate B17 fixedly connected to the placement plate 16, a heating plate top column 18, and a return spring 19, and the return spring 19 and the heating plate top column 18 form a reset mechanism. In fact, the heating plate top column 18 is plugged into the guide hole of the base 10 to guide the placement plate 16 to move up and down.

[0043] In fact, the heating unit is lifted and lowered by the return spring 19, or by other reset members with reset function.

[0044] In fact, when the heating unit is lifted and lowered in the cutting die 15, it has a maximum compression stroke. When the heating unit is in the maximum compression stroke, the heating unit is in the cutting die 15, and the top of the heating plate top column 18 is in conflict with the base 10. When the heating unit is in an uncompressed state, the top plane of the heating unit is higher than the top of the cutting die 15, which protects the top of the cutting die 15, and the bottom of the heating plate top column 18 is in conflict with the base 10. In fact, when the heating unit is in an uncompressed state, the top plane of the heating unit is 3-5 mm higher than the top of the cutting die 15, and also includes when the top plane of the heating unit is 15-20 mm lower than the top of the cutting die 15 in the maximum compression state.

[0045] See also Figure 2 The pressing unit is provided with a guide post 31 toward the positioning frame 11, and the positioning frame 11 is provided with a guide hole plugged with the guide post 31. In fact, the pressing unit is guided and moved by the guide post 31, contacts the positioning frame 11, and presses the organic glass.

[0046] In some embodiments, the pressing unit guide can also use a slide rail, which makes the lifting process smoother and shortens the lifting process time. Figure 2 A discharge mechanism is provided between the laminating unit and the heating unit, and the discharge mechanism is located between the two positioning frames 11. In addition, the discharge mechanism is used to push the organic glass out of the heating unit in a direction away from the positioning frame 11; when the laminating unit and the heating unit are pressed together, the side of the organic glass slides in contact with the discharge mechanism.

[0047] In fact, the discharge mechanism is located between the heating unit and the pressing unit, and the movement direction of the discharge mechanism is parallel to the plane of the placement plate 16, pushing the plexiglass out along the movement direction of the discharge mechanism. In addition, during the pressing process, the discharge mechanism is in sliding contact with the plexiglass to avoid interfering with the pressing of the plexiglass.

[0048] See also Figure 3 The discharging mechanism includes a pushing plate 23 and a pushing member 21 for displacing the pushing plate 23 . The pushing plate 23 is located between the two positioning frames 11 . When the heating unit is reset, the pushing plate 23 is driven by the pushing member 21 to push the organic glass out.

[0049] In fact, after the pressing and cutting operation is completed, the push plate 23 contacts the organic glass, and the push member 21 drives the screw rod 22 to drive the push plate 23 to push the organic glass out of the heating unit. Specifically, the push member 21 is a motor.

[0050] In some embodiments, the lifting mechanism of the positioning frame 11 is disposed at the bottom of the positioning frame 11, and when the pressing unit is pressed downward, the positioning frame 11 is driven by the pressing unit to perform lifting and lowering movements. In fact, the positioning frame 11 needs to be lifted and lowered by pressing the pressing unit through the lifting mechanism, and the positioning frame 11 is also provided with a top column of the positioning frame 11 that is plugged into the guide hole on the base 10. Specifically, the reset mechanism is composed of a return spring 13 and a top column of the positioning frame 11.

[0051] In fact, the positioning frame 11 is lifted and moved on the base 10. When the positioning frame 11 has the maximum compression stroke, the bottom of the positioning frame 11 contacts the base 10, and the pressing unit interferes with the movement of the positioning frame 11, so that the positioning frame 11 is fixed to ensure that the glass can be fully pressed after being cut through. When the positioning frame 11 is not in a compressed state, the bottom of the positioning frame top column 12 contacts the base 10. Specifically, the base 10 is used to limit the positioning frame top column 12 from sliding out of the guide hole, so as to control the lifting stroke of the positioning frame 11.

[0052] In some embodiments, the top column 12 of the positioning frame is plugged into the guide hole on the base 10 to improve the lifting stability of the positioning frame 11.

[0053] In some embodiments, after the pressing and cutting is completed, the positioning frame 11 is reset, the positioning frame 11 is in sliding contact with both sides of the pushing plate 23 , and the pushing member 21 pushes the screw rod 22 to drive the pushing plate 23 to push the organic glass out of the positioning frame 11 .

[0054] See also Figure 3 , the push plate 23 contacts the positioning frame 11 and positions the unpressed organic glass. In fact, before pressing, the organic glass is placed on the placement plate 16, and the organic glass is in contact with the push plate 23 and the positioning frame 11, so that the two organic glasses are aligned, ensuring the maximum contact area of ​​the two organic glasses to avoid wasting materials.

[0055] In some embodiments, the positioning frame 11 is fixed on the base 10 to position the organic glass, but when it contacts the glass, it will produce large friction and easily get stuck.

[0056] See also Figure 3 The base 10 is provided with a discharging platform 14 along the direction in which the discharging mechanism pushes out the organic glass, and the discharging platform 14 is used for temporarily storing the organic glass.

[0057] In fact, a discharge platform 14 is installed on the side of the base 10. After the pressing and cutting are completed, the discharge mechanism pushes the organic glass out of the positioning frame 11, and the material reaches the discharge platform 14. The temporary storage of the material can expose the material to the air for cooling, so that the organic glass is not easily deformed in subsequent work, which is convenient for batch transportation.

[0058] See also Figure 3 A separation port is provided on the discharge table 14 for separating the cut organic glass. In addition, the separation port is adapted to the shape of the knife die 15 , and the opening area of ​​the separation port is greater than or equal to the cutting area of ​​the knife die 15 .

[0059] In fact, the shape cut by the knife die 15 is square, and the separation port on the discharge platform 14 is also square, and the separation port is greater than or equal to the shape specification cut by the knife die 15. In addition, when the plexiglass is pushed out to the discharge platform 14, the cut plexiglass falls into the separation port, and the waste is pushed out of the discharge platform 14, so as to separate the materials and facilitate the subsequent batch operation.

[0060] Although the embodiments of the present invention are described in detail above, it is obvious to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention as described in the claims. Moreover, the present invention described herein may have other embodiments and may be implemented or realized in a variety of ways.
