Description

Technical Field

[0001] The utility model relates to the technical field of horizontal and vertical slitting machines, in particular to an automatic knife adjustment structure for a pearl cotton horizontal and vertical slitting machine. Background Art

[0002] Pearl cotton, also known as polyethylene foam or PE foam, is a lightweight, closed-cell foam plastic material. It is made of polyethylene resin through a foaming process and has many tiny bubble structures. These bubbles form independent closed spaces inside the material, giving the pearl cotton unique physical properties. When processing pearl cotton, a pearl cotton horizontal and vertical slitting machine is required.

[0003] The pearl cotton horizontal and vertical slitting machine is a cutting equipment used in industrial production, which is specially used to cut pearl cotton into the required size and shape. The horizontal and vertical slitting machine cuts the pearl cotton material in both horizontal and vertical directions during processing. It often uses a circular knife with adjustable spacing for vertical cutting, and then uses an intermittent up and down moving cutter for horizontal cutting.

[0004] During specific production and processing, under different processing requirements, the cutting size required for pearl cotton is often different. When its length needs to be adjusted, it is often sufficient to adjust the cutting spacing of the cutter that moves up and down. When its width needs to be adjusted, the spacing of the circular knives needs to be adjusted, which means that all the circular knives need to be adjusted one by one. This adjustment method requires a lot of downtime for the horizontal and vertical slitting machines during adjustment, which seriously affects the processing effect of the equipment.

[0005] In view of this, an automatic knife adjustment structure for a pearl cotton horizontal and vertical slitting machine is proposed. Utility Model Content

[0006] The utility model aims to solve the problem that the positions of circular knives need to be adjusted one by one when adjusting the knives of a horizontal and vertical slitting machine, and provides an automatic knife adjusting structure for a pearl cotton horizontal and vertical slitting machine.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions: an automatic knife adjustment structure of a pearl cotton horizontal and vertical slitting machine, comprising a mounting frame and a sliding rod fixedly connected to the mounting frame, a cutting module is arranged on the sliding rod, and the cutting module comprises a fixed knife group fixedly connected to the middle part of the sliding rod, two first knife groups slidably arranged on the sliding rod and respectively located on both sides of the fixed knife group, and two second knife groups slidably arranged on the sliding rod and respectively located at both ends of the sliding rod, a bidirectional screw is rotatably installed on the mounting frame, the bidirectional screw is used to drive the first knife group and the second knife group to move to complete the knife adjustment operation, and a first motor for driving the bidirectional screw to rotate is fixedly installed on the mounting frame.

[0008] Furthermore, the fixed knife assembly includes a bracket fixedly mounted on the slide rod and a circular knife for cutting rotatably mounted on the bracket, and a second motor for driving the circular knife to rotate is fixedly connected to the bracket.

[0009] Furthermore, the first knife group and the second knife group both include a bracket slidably arranged on the slide rod and a circular knife rotatably mounted on the bracket for cutting.

[0010] Furthermore, a first sliding hole is provided on the brackets of the first knife group and the second knife group, and the first sliding hole is used to sleeve the first knife group or the second knife group on the sliding rod.

[0011] Furthermore, a second sliding hole is formed on both the first knife assembly and the second knife assembly.

[0012] Furthermore, the bidirectional screw is provided with a first thread segment in a mirror-like arrangement, and the first thread segments on both sides are threadedly connected with a first screw sleeve, the first screw sleeve is located in the second sliding hole of the first tool group and is rotatably connected to the bracket of the first tool group, and the bidirectional screw is provided with a second thread segment in a mirror-like arrangement, and the second thread segments on both sides are threadedly connected with a second screw sleeve, the second screw sleeve is located in the second sliding hole of the second tool group and is rotatably connected to the bracket of the second tool group.

[0013] Further, the pitch of the thread of the second thread segment is twice the pitch of the thread of the first thread segment.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the automatic knife adjustment structure of the pearl cotton horizontal and vertical slitting machine provided by the utility model can synchronously adjust the two first knife groups and the two second knife groups through the rotation of the bidirectional screw, so that the two first knife groups and the two second knife groups are equidistant from each other or away from the fixed knife group, which greatly improves the knife adjustment efficiency of the horizontal and vertical slitting machine. In addition, through the threaded connection relationship between the first knife group, the second knife group and the bidirectional screw, the accuracy of knife adjustment can be improved, ensuring that the distance between the circular knives can be kept consistent, and further improving the processing accuracy of the horizontal and vertical slitting machine.

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. 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.

[0023] See also Figure 1-5 .

[0024] The utility model discloses an automatic knife-adjusting structure for a pearl cotton horizontal and vertical slitting machine, comprising a mounting frame 1 and a slide bar 2 fixedly connected to the mounting frame 1, a cutter module 4 is arranged on the slide bar 2, and the cutter module 4 comprises a fixed knife group 41 fixedly connected to the middle part of the slide bar 2, two first knife groups 42 slidingly arranged on the slide bar 2 and respectively located on both sides of the fixed knife group 41, and two second knife groups 43 slidingly arranged on the slide bar 2 and respectively located at both ends of the slide bar 2, a bidirectional screw rod 3 is rotatably installed on the mounting frame 1, and the bidirectional screw rod 3 is used to drive the first knife group 42 and the second knife group 43 to move to complete the knife-adjusting operation, and a first motor 31 for driving the bidirectional screw rod 3 to rotate is fixedly installed on the mounting frame 1.

[0025] That is to say, the knife adjustment method of the device is that the fixed knife group 41 remains stationary, and the positions of the first knife group 42 and the second knife group 43 on both sides of the fixed knife group 41 are adjusted by the bidirectional screw 3 to adjust the distance between each circular knife 410 to complete the knife adjustment.

[0026] Secondly, the fixed knife group 41 includes a bracket 44 fixedly mounted on the slide rod 2 and a circular knife 410 for cutting rotatably mounted on the bracket 44, and a second motor 49 for driving the circular knife 410 to rotate is fixedly connected to the bracket 44. The first knife group 42 and the second knife group 43 both include a bracket 44 slidably set on the slide rod 2 and a circular knife 410 for cutting rotatably mounted on the bracket 44, and a second motor 49 for driving the circular knife 410 to rotate is fixedly connected to the bracket 44.

[0027] It should be noted that the fixed knife group 41 is fixedly installed on the slide rod 2, the two first knife groups 42 and the two second knife groups 43 are all slidably set on the slide rod 2, and the fixed knife group 41, the first knife group 42 and the second knife group 43 all include a bracket 44, a second motor 49 and a circular knife 410.

[0028] Again, the brackets 44 of the first knife group 42 and the second knife group 43 are both provided with a first sliding hole 45, and the first sliding hole 45 is used to sleeve the first knife group 42 or the second knife group 43 on the slide rod 2, and the first knife group 42 and the second knife group 43 are both provided with a second sliding hole 46.

[0029] Specifically, the bidirectional screw rod 3 is provided with a first threaded segment 32 in a mirror-like arrangement, and the first threaded segments 32 on both sides are threadedly connected with a first screw sleeve 47, the first screw sleeve 47 is located in the second sliding hole 46 of the first tool group 42 and is rotatably connected to the bracket 44 of the first tool group 42, and the bidirectional screw rod 3 is provided with a second threaded segment 33 in a mirror-like arrangement, and the second threaded segments 33 on both sides are threadedly connected with a second screw sleeve 48, the second screw sleeve 48 is located in the second sliding hole 46 of the second tool group 43 and is rotatably connected to the bracket 44 of the second tool group 43.

[0030] like Figure 3 As shown, there are two first thread segments 32 and two second thread segments 33 on the bidirectional screw 3, wherein the two first thread segments 32 are mirror-symmetrical at both ends of the slide rod 2, and the two second thread segments 33 are mirror-symmetrical at both ends of the slide rod 2, that is, when the bidirectional screw 3 rotates, the two first screw sleeves 47 approach or move away from each other, and the two second screw sleeves 48 also approach or move away from each other.

[0031] like Figure 5 As shown, the outer sides of the first screw sleeve 47 and the second screw sleeve 48 are provided with a T-shaped swivel ring for rotatably connecting the two with the bracket 44 of the first knife group 42 or the second knife group 43. When the bidirectional screw 3 rotates, the first screw sleeve 47 and the second screw sleeve 48 will drive the first knife group 42 and the second knife group 43 to move respectively.

[0032] It should be noted that the pitch of the thread of the second thread segment 33 is twice the pitch of the thread of the first thread segment 32 shown, that is, when the bidirectional screw 3 rotates, the moving distance of the second screw sleeve 48 is twice that of the first screw sleeve 47, that is, the moving distance of the second knife group 43 on the slide rod 2 when moving is twice that of the first knife group 42, so that the distance between the first knife group 42 and the second knife group 43 is always consistent with the distance between the first knife group 42 and the fixed knife group 41, that is, the spacing between the five circular knives 410 is always consistent, so that when adjusting the spacing of the circular knives 410, it is only necessary to rotate the bidirectional screw 3 forward or reverse and control the rotation angle.

[0033] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
