Summary of the invention:

[0006] The object of the present invention is to provide a stable reciprocating horizontal blade sponge cutting machine to solve one or more of the above-mentioned prior art problems.

[0007] In order to solve the above technical problems, the present invention provides a stable reciprocating horizontal blade sponge cutting machine, whose structure includes a gantry, and a knife belt for cutting sponge is horizontally arranged at the bottom of the gantry. The innovation point is that: symmetrical first steering assemblies are arranged at both ends of the bottom of the gantry, and symmetrical second steering assemblies are arranged at both ends of the top of the gantry. Both the first steering assembly and the second steering assembly are rotatably arranged on the gantry, and a cross bar is arranged between the two second steering assemblies. Vertical rods and connecting rods are respectively arranged between the first steering assembly and the second steering assembly. The vertical rods and the connecting rods are respectively located at both ends of the gantry, and the two first steering assemblies are respectively connected to the two ends of the knife belt with driving rods, and a driving assembly for driving the connecting rod to reciprocate up and down is provided on the gantry.

[0008] Furthermore, when the driving assembly drives the connecting rod to move upward, the first steering assembly and the second steering assembly rotate clockwise on the gantry and cause the connecting rod, the cross rod, the vertical rod, and the driving rod to move upward, rightward, downward, and leftward, respectively.

[0009] Furthermore, when the driving assembly drives the connecting rod to move downward, the first steering assembly and the second steering assembly rotate counterclockwise on the gantry and cause the connecting rod, the cross rod, the vertical rod, and the driving rod to move downward, leftward, upward, and rightward, respectively.

[0010] Furthermore, when the driving rod moves left and right, the knife belt is driven to move left and right at the bottom of the gantry.

[0011] Furthermore, the above-mentioned first steering assembly includes a first rotating bearing, a first rotating rod a and a first rotating rod b parallel to the knife belt, the ends of the first rotating rod a and the first rotating rod b are fixed perpendicularly to each other on the first rotating bearing, the lengths of the first rotating rod a and the first rotating rod b are the same, the bottom of the first rotating rod a is vertically downward and on the same horizontal line as the knife belt, the driving rod is fixed between the knife belt and the first rotating rod a, the extension directions of the two first rotating rods b are relatively arranged and are respectively fixed perpendicularly to the bottom of the connecting rod and the bottom of the vertical rod, and when the first steering assembly rotates, the first rotating rod a and the first rotating rod b make synchronous rotational motion with the first rotating bearing as the center.

[0012] Furthermore, the above-mentioned second steering assembly includes a second rotating bearing arranged on the top of the gantry, a second rotating rod a parallel to the knife belt, and a second rotating rod b.

When the second steering assembly rotates, the second rotating rod a and the second rotating rod b make synchronous rotational motion with the second rotating bearing as the center.

[0013] Furthermore, the above-mentioned driving assembly includes a rotating motor and a rocking arm arranged on the gantry, the rotating motor is provided with a cam, the cam is connected to a moving rod parallel to the connecting rod, one end of the rocking arm can be rocked up and down on the gantry, the other end of the rocking arm is vertically fixed to the moving rod, and the other end of the rocking arm extends outward with two inclined rods, the two inclined rods are inclined toward the top and bottom of the connecting rod respectively and are fixedly connected to the connecting rod respectively.

[0014] The beneficial effects of the present invention are as follows: the present invention provides a stable reciprocating horizontal knife sponge cutting machine.

[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0019] like Figure 1 It is a specific embodiment of the present invention, and its structure includes a gantry 1, a knife belt 2 for cutting sponge is horizontally arranged at the bottom of the gantry 1, symmetrical first steering components 3 are arranged at both ends of the bottom of the gantry 1, and symmetrical second steering components 4 are arranged at both ends of the top of the gantry 1. The first steering component 3 and the second steering component 4 are rotatably arranged on the gantry 1, a cross bar 5 is arranged between the two second steering components 4, a vertical rod 6 and a connecting rod 7 are respectively arranged between the first steering component 3 and the second steering component 4, the vertical rod 6 and the connecting rod 7 are respectively located at both ends of the gantry 1, the two first steering components 3 are respectively connected to the two ends of the knife belt 2 with driving rods 8, and the gantry 1 is provided with a driving component 9 for driving the connecting rod 7 to move reciprocally up and down.

[0020] The working principle of the present invention is as follows: when cutting the sponge workpiece, turn on the driving assembly 9. When the driving assembly 9 drives the connecting rod 7 to move upward, the first steering assembly 3 and the second steering assembly 4 rotate clockwise on the gantry 1 and make the connecting rod 7, the cross bar 5, the vertical bar 6, and the driving rod 8 move upward, rightward, downward, and leftward respectively. At this time, the driving rod 8 drives the knife belt 2 to move leftward on the gantry 1, and the knife belt 2 cuts the sponge workpiece. When the driving assembly 9 drives the connecting rod 7 to move downward, the first steering assembly 3 and the second steering assembly 4 rotate counterclockwise on the gantry 1 and make the connecting rod 7, the cross bar 5, the vertical bar 6, and the driving rod 8 move upward, rightward, downward, and leftward respectively. The rod 5, the vertical rod 6 and the driving rod 8 move downward, leftward, upward and rightward respectively. At this time, the driving rod 8 drives the knife belt 2 to move rightward on the gantry 1, and the knife belt 2 continues to cut the sponge workpiece. In the process of the knife belt 2 cutting the sponge workpiece, a driving component 9 drives the knife belt 2 to move back and forth to cut the sponge workpiece, which saves energy. At the same time, through the clockwise rotation and counterclockwise rotation of the first steering component 3 and the second steering component 4, the motion transmission between the driving rod, the vertical rod, the cross rod and the connecting rod is more stable, thereby improving the stability of the reciprocating movement of the knife belt 2.

[0021] In the present invention, in order to specifically illustrate the specific structure of the first steering assembly 3, the first steering assembly 3 includes a first rotating bearing 31, a first rotating rod a32, and a first rotating rod b33 parallel to the knife belt 2, the ends of the first rotating rod a32 and the first rotating rod b33 are fixed perpendicularly to each other on the first rotating bearing 31, the lengths of the first rotating rod a32 and the first rotating rod b33 are the same, the bottom of the first rotating rod a32 is vertically downward and on the same horizontal line as the knife belt 2, and the driving rod 8 is fixed between the knife belt 2 and the first rotating rod a3 2, the extension directions of the two first rotating rods b33 are relatively arranged and are respectively fixed vertically to the bottom of the connecting rod 7 and the bottom of the vertical rod 6. When the first steering assembly 3 rotates, the first rotating rod a33 and the first rotating rod b33 make synchronous rotational motion with the first rotating bearing 31 as the center. By setting the length and position of the first rotating rod a32 and the first rotating rod b33, during the synchronous rotation of the first rotating rod a32 and the first rotating rod b33, the motion transmission between the two driving rods 8 and the bottom of the vertical rod 6 and the bottom of the connecting rod 7 is more stable.

[0022] In the present invention, in order to specifically illustrate the specific structure of the second steering assembly 4, the above-mentioned second steering assembly 4 includes a second rotating bearing 41 arranged at the top of the gantry 1, a second rotating rod a42 parallel to the knife belt 2, and a second rotating rod b43. The ends of the second rotating rod a42 and the second rotating rod b43 are fixed perpendicularly to each other on the second rotating bearing 41. The lengths of the second rotating rod a42 and the second rotating rod b43 are consistent. The extension directions of the two second rotating rods a42 are relatively arranged and are respectively vertically connected to the top of the connecting rod 7 and the top of the vertical rod 6. The end of the second rotating rod b43 is vertically upward and the cross bar 5 is fixed between the second rotating rods b43. When the second steering assembly 4 rotates, the second rotating rod a42 and the second rotating rod b43 perform synchronous rotational motion with the second rotating bearing 41 as the center. By setting the length and position of the second rotating rod a42 and the second rotating rod b43, during the synchronous rotation of the second rotating rod a42 and the second rotating rod b43, the motion transmission between the two ends of the cross bar 5, the top of the vertical rod 6 and the top of the connecting rod 7, is more stable.

When the driving assembly 9 drives the connecting rod 7 to move up and down reciprocatingly , using the rotating motor 91 as the power, through the movement transmission of the cam 911, the moving rod 101 is moved up and down along the extension direction of the connecting rod 7 (the movement steering of the cam 911 belongs to the prior art, and is not described in detail in the present invention), thereby pushing the rocking rod 92 to swing up and down, and the up and down swinging of the rocking rod 92 drives the connecting rod 7 to move up and down through the tilting rod 102. Specifically, the up and down swinging distance of the rocking rod 92 is consistent, so that the counterclockwise and clockwise rotation angles of the first steering assembly 3 and the second steering assembly 4 are consistent, so that the distance of the left and right movement of the knife belt is consistent, thereby further improving the stability of the left and right reciprocating movement of the knife belt 2.
