[0030] 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.
[0031] Such as Figures 1 to 7As shown in the figure, an EPS foam board hot cutting device includes a conveying device 1. On both sides of the conveying device 1, a connecting seat 3 and a first electric push rod 2 for driving the connecting seat 3 to move up and down are respectively arranged. On one side of the connecting seat 3, a limiting seat 4 and a second electric push rod 31 for driving the limiting seat 4 to move back and forth are arranged. A plurality of slidable sliders 6 are slidably arranged on the limiting seat 4. The two symmetrically corresponding sliders 6 on both sides of the conveying device 1 are connected by a heating wire 7 in a transitional manner. An adjusting seat 5 and a third electric push rod 33 for driving the adjusting seat 5 to move left and right are arranged outside the limiting seat 4. The adjusting seat 5 is provided with adjusting grooves 51 corresponding to the sliders 6 one by one. The plurality of adjusting grooves 51 are arranged in a divergent shape. A limiting block 52 is arranged outside the adjusting seat 5. A plurality of uniformly arranged third limiting grooves 521 are arranged on the limiting block 52. The third limiting grooves 521 coincide with the corresponding adjusting grooves 51. The distance between two adjacent adjusting grooves 51 in the same vertical plane is the same. A limiting plug 62 that passes through the adjusting groove 51 and inserts into the corresponding third limiting groove 521 is arranged on one side of the slider 6 facing the adjusting seat 5.
[0032] Specifically, in this embodiment, the conveying device 1 adopts a roller conveyor. Fixed frames 11 are respectively arranged on both sides of the roller conveyor. The first electric push rods 2 are respectively fixed on the corresponding fixed frames 11.
[0033] Further, in this embodiment, the fixed frame 1 and the connecting seat 3 can be connected in a transitional manner through a slide rail and a slider to increase the stability of the up and down sliding of the connecting seat 3.
[0034] As a specific implementation manner, as Figures 5 to 7 shown, a first limiting groove 41 extending up and down is arranged on the limiting seat 4. A second limiting groove 42 is arranged on the side of the first limiting groove 41 facing the adjusting seat 5 and around the first limiting groove 41. The slider 6 is slidably arranged in the first limiting groove 41. A limiting portion 61 is arranged on one side of the slider 6. The limiting portion 61 is slidably arranged in the second limiting groove 42. In this way, under the action of the first limiting groove 41, the slider 6 is restricted to move only up and down. Under the limiting action of the second limiting groove 42 on the limiting portion 61, the slider 6 is prevented from moving inward (the side where the sliders 6 on both sides of the transmission device 1 face each other is the inner side). Under the pulling force of the heating wire 7 and the shielding action of the adjusting seat 5 on the limiting portion 61, the slider 6 is prevented from moving outward (the side where the sliders 6 on both sides of the transmission device 1 face away from each other is the outer side). In summary, the slider 6 can only move up and down along the first limiting groove 41.
[0035] Working principle: When adjusting the spacing of the heating wire 7, first, the third electric push rod 33 drives the adjusting seat 5 to move outward, so that the limit plug 62 disengages from the corresponding third limit groove 521. It should be noted here that the third electric push rod 33 only drives the adjusting seat 5 to move to disengage the third limit groove 521 from the limit plug 62, and the limit plug 62 is still in the adjusting groove 51. In this way, when the second electric push rod 31 drives the limit seat 4 to move back and forth, under the guiding action of the divergently arranged adjusting grooves 51, all the heating wires 7 move up and down evenly and synchronously, and finally the spacing is increased by diffusion or decreased by reduction. When the spacing of the required cutting thickness is adjusted, the third electric push rod 33 is used to push the adjusting seat 5 to move inward again and at the same time make the limit plug 62 inserted and matched with the corresponding third limit groove 521, so as to form a vertical movement limit for the slider 6 and completely fix the slider 6.
[0036] As Figure 8 shown, for the adjusting grooves 51 arranged in a divergently structured manner, when the spacing between two adjacent adjusting grooves 51 in the same vertical plane is the same, each corresponding adjusting groove 51 extends linearly. In this way, it not only ensures that the spacing between all the adjusting grooves 51 in the same vertical plane is the same, but also enables the limit plug 62 to slide evenly under force in the adjusting groove 51.
[0037] In addition, according to the up and down positions of the adjusted heating wire 7 and the thickness of the EPS foam board to be cut, the first electric push rod 2 can be further used to drive the connecting seat 3 to move up and down, and finally complete the overall up and down height adjustment of all the heating wires.
[0038] After adjusting the cutting thickness and the cutting height, place the EPS foam board to be cut on the conveying device 1. The conveying device 1 drives the EPS foam board to move. When it moves to the position of the heating wire 7, the EPS foam board can be cut. When the EPS foam board completely passes through the heating wire 7, the cutting is completed.
[0039] Specifically, in this embodiment, a support seat 32 is fixedly connected to the connecting seat 3 through a connecting rod, and the third electric push rod 33 is fixed on the support seat 32. Preferably, a plurality of the third electric push rods 33 are evenly connected around the adjusting seat 5, and the plurality of the third electric push rods 33 drive the adjusting seat 5 to move synchronously, increasing the smoothness and stability of the movement of the adjusting seat 5.
[0040] Preferably, two second electric push rods 31 are used. The driving arms of the two second electric push rods 31 are respectively connected to the upper and lower ends of the limit seat 4, also increasing the smoothness and stability of the movement of the limit seat 4.
[0041] Furthermore, as Figure 7As shown, a chamfered portion 522 is provided on one side of the third limiting groove 521 facing the limiting plug 62. The chamfered portion 522 can provide a guiding for the insertion of the limiting plug 62 into the third limiting groove 521, improve the insertion range, and enable the limiting plug 62 to be inserted into the third limiting groove 521 more smoothly.
[0042] Furthermore, as Figure 7 shown, the slider 6 and the heating wire 7 are connected by a tension spring 63 in a transitional manner. The heating wire is straightened by the tension spring 63, which not only ensures the straightness of the heating wire but also improves the compressive toughness of the heating wire to prevent breakage due to excessive tension.
[0043] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
