[0002] Application No. 202111519330.8 is a shoe material punch cutting machine. Figure 7 It can be seen that the Y-axis gear (30) and the Y-axis rack (31) are both exposed to the outside. Leather punching will generate a large amount of dust and debris. During use, these dust and debris will float onto the gear and the rack. After accumulating to a certain amount, the gear will not be able to mesh normally with the teeth on the rack, resulting in material jamming. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a cutting machine anti-stuck material mechanism and a cutting machine thereof, which are used to solve the problem of dust and debris entering the rack and gear.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a cutting machine anti-stuck material mechanism, applied to the cutting machine, used to cover the moving track that guides the movement of the cutter head assembly, characterized in that the blocking belt is extended to both ends of the moving track in the form of being attached to the outside of the moving component, and the moving track exposed when the moving component is moving is covered by the above-mentioned blocking belt. The moving component is a component in the cutting machine that drives the cutter head assembly to move back and forth on the moving track.

[0005] Furthermore, the barrier belt covers the moving track in a stretched state.

[0006] Furthermore, a ratchet group adjustment component is also included, and the ratchet group adjustment component pulls the two ends of the barrier belt into a stretched and straight state.

[0007] Furthermore, the ratchet group adjustment component includes a ratchet, a pawl, a pressure seat with an adjusting wheel rod, and a torsion spring. The end of the retaining belt is connected to the circumferential surface of the adjusting wheel rod. The two ends of the adjusting wheel rod pass through the pressure seat, and one end thereof is covered by the above-mentioned ratchet. The surface of the pressure seat adjacent to or in contact with the ratchet is the first surface. The pawl is rotatably connected to the first surface and meshes with the ratchet. A concave surface is also provided on the first surface. The first end of the torsion spring abuts against the inner side wall of the concave surface, and the second end of the torsion spring abuts against the first side of the pawl.

[0008] Furthermore, it also includes a plurality of belt guide wheels for guiding the barrier belt to avoid the driving assembly and maintaining the barrier belt attached to the outer surface of the driving assembly to cover the connection of the subsequently exposed moving track.

[0009] Furthermore, the staggered positions between the belt guide wheels on the driving assembly are used to guide the barrier belt to avoid the driving assembly and fit on the driving assembly, and the barrier belt is staggered around the belt guide wheels at the staggered positions.

[0010] Furthermore, the other end of the adjusting wheel rod is a connection port used with an external adjusting device.

[0027] Figure 1 It is a three-dimensional diagram of the structure of the mobile component part.

[0028] As can be seen from the figure, the moving track is exposed, and the driving gear Y in the moving assembly is meshed with the rack X in the moving track. When the driving gear Y rotates, the cutter head assembly on the moving assembly moves back and forth along the length direction of the rack X.

[0029] Figure 3 This is a three-dimensional picture of the cutting machine's anti-stuck mechanism applied to the moving track.

[0030] The anti-stuck material mechanism of the cutting machine is located at both ends of the cutting machine 1 . The cutting machine 1 is composed of two cutting devices spliced ​​together, and the two cutting devices share the same console assembly 10 .

[0031] like Figure 2-5 As shown, the anti-jamming mechanism of the cutting machine includes a housing 2 and a ratchet group adjustment component 3, a belt guide wheel 4, and a blocking belt 5 located in the housing 2. The belt guide wheel 4 is arranged on the outside of the moving component. The blocking belt 5 is wound around the belt guide wheel 4 and covers the exposed moving track to isolate dust and debris from the outside, prevent dust and debris from entering the moving track, and avoid affecting the transmission between the rack X and the driving gear Y, thereby solving the problem of material jamming;

[0032] It can be seen that the greatest feature of the anti-jamming mechanism of the cutting machine is that it can block debris and dust from the moving components of the cutter head assembly, thereby assisting the normal operation of the moving components.

[0033] Furthermore, the anti-stuck material mechanism of the cutting machine is designed based on the structure of the moving component connected to the cutter head assembly. Therefore, it can be used in conjunction with the cutter head assembly without any interference with the cutter head assembly.

[0034] like Fig.11As shown, the belt guide wheels 4 have multiple, especially two belt guide wheels 4 that guide the barrier belt 5 from the outermost surface of the moving component to the moving track. The barrier belt 5 is staggered and wound on the above-mentioned upper belt guide wheels 4. Under the action of the belt guide wheels 4, the barrier belt 5 is attached to the three surfaces of the moving component. Therefore, the design of the belt guide wheels 4 has the function of lifting the barrier belt 5 from the moving track to allow the driving gear Y and the rack X to engage when the moving component moves forward, and covering the moving track exposed at the rear when the moving component moves. The covering is that the belt guide wheels 4 constrain the barrier belt 5 to cover the moving track.

[0035] The blocking belt 5 is preferably in a stretched state, on this basis, the blocking effect of the blocking belt 5 is optimal.

[0036] In this embodiment, a pair of ratchet adjustment components 3 are used, and the two ends of the stop belt 5 are pulled by the ratchet adjustment components 3 to form a straight state.

[0037] It should be noted that the blocking effect of the cutting machine anti-jamming mechanism of the present invention is not only against debris, dust, etc., but also against materials and components that exist in the outside world and affect the normal operation of the moving components.

[0038] like Figure 6-8 As shown, the ratchet adjustment assembly 3 includes a ratchet 31, a pawl 32, a pressure seat 33 with an adjustment wheel rod 34, and a torsion spring 35. The two ends of the adjustment wheel rod 34 extend out of the pressure seat 33, one end of which is a connection port for use with an external adjustment device, and the other end is covered by the ratchet 31. The surface of the pressure seat 33 adjacent to or in contact with the ratchet 31 is a first surface 33'. The pawl 32 is rotatably connected to the first surface 33' and meshes with the ratchet 31. The first surface 33' is also provided with a concave surface 33'-a, and the first end 35a of the torsion spring 35 abuts against the first surface 33'. On the inner wall of the concave surface 33'-a, the second end 35b of the torsion spring 35 is against the first side 32' of the pawl 32. When the barrier belt 5 needs to be adjusted to a straight state, the adjusting wheel rod 34 is rotated to make the barrier belt 5 wrap around the adjusting wheel rod 34. At the same time, the teeth of the ratchet 31 will push the pawl 32 to separate the pawl 32 from the ratchet 31. Under the rebound of the torsion spring 35, the pawl 32 engages with other teeth on the ratchet 31, thereby inhibiting the adjusting wheel rod 34 from rotating in the opposite direction and keeping the barrier belt 5 in a straight state.

[0039] In addition, both ends of the barrier belt 5 are fixed to the adjusting wheel rod 34 by screws to prevent the barrier belt 5 from falling off the adjusting wheel rod 34 .

[0040] It also includes a positioning screw. A threaded hole is provided on the concave surface 33'-a. An opening structure for the positioning screw to pass through is preset on the torsion spring 35. After the positioning screw passes through the torsion spring 35, it is threadedly connected with the screw hole to constrain the torsion spring 35 on the concave surface 33'-a.

[0041] Figure 2 and Fig. 9 Two groups of cutter head assemblies are shown, namely the first cutter head assembly 6, the second cutter head assembly 7, the third cutter head assembly 8, and the fourth cutter head assembly 9. The second cutter head assembly 7 and the third cutter head assembly 8 are opposite to each other, the second cutter head assembly 7 is facing away from the first cutter head assembly 6, and the third cutter head assembly 8 is facing away from the fourth cutter head assembly 9.

[0042] The first blade assembly 6 or the fourth blade assembly 9 is used to punch holes in the leather, and the second blade assembly 7 and the third blade assembly 8 are used to cut, in order to improve the cutting efficiency and enable quick punching of the leather;

[0043] In addition, the time difference between cutting and punching can be reduced, so that the time spent on cutting and punching the leather is the same or nearly the same, and the first cutter head assembly 6 or the fourth cutter head assembly 9 will not stop waiting for the second cutter head assembly 7 or the third cutter head assembly 8.

[0044] Fig.10 This is another cutting machine in the second embodiment that uses the above-mentioned cutting machine material jamming prevention mechanism.

[0045] In this cutting machine, the first cutter head assembly 6a and the second cutter head assembly 7a are opposite to each other, and the third cutter head assembly 8 and the fourth cutter head assembly 9 are opposite to each other.

[0046] The cutter head assembly mentioned above has patent number CN202221265278.8 and is named CNC multifunctional combined cutter head.

[0047] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
