[0001] The utility model relates to the technical field of multi - cutter rubber cutting machines, and specifically relates to a multi - cutter rubber cutting machine. Background Art

[0002] A rubber cutting machine is a rubber processing device, and its function is to cut rubber blocks of natural rubber or synthetic rubber into smaller rubber blocks that are easy to process. Rubber is a solid with high elasticity and toughness. During the production process of rubber pipes, a rubber cutting machine is required to cut large rubber blocks into small pieces, then roll them into sheets, and finally attach the sheets to the pipe mold to heat - form rubber pipes and then demold.

[0003] Existing rubber cutting machines all have a single cutter head and can only cut once at a time. Multiple operations are required to cut the desired rubber block. When cutting, it can only cut the rubber block horizontally and cannot cut vertically or obliquely, and cannot cut at the desired angle. For this reason, we provide a multi - cutter rubber cutting machine to solve the above problems. Content of the Utility Model

Specific embodiments

[0026] 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.

[0027] Embodiment 1

[0028] As Figures 1-7 shown, a technical solution is provided: a multi-cutter head rubber cutting machine, including a base 1, a fixing frame 3 fixed on the base 1 through a three-legged block 2, a hydraulic rod 4 fixed in the middle of the upper part of the fixing frame 3, a rotating groove 11 opened at the bottom end of the hydraulic rod 4, a rotatable rotating block 5 arranged at the rotating groove 11 at the bottom end of the hydraulic rod 4, and a clamping mechanism 6 fixed at the bottom end of the rotating block 5. By arranging the rotating groove 11 and the rotating block 5 at the bottom end of the hydraulic rod 4, the clamping mechanism 6 and the first cutter head 7 or the second cutter head 71 can be rotated, and the cutting angle can be changed during cutting to realize cutting of rubber blocks at different angles. An elastic component 61 is arranged inside the clamping mechanism 6, and the first cutter head 7 or the second cutter head 71 is clamped at the bottom end of the clamping mechanism 6;

[0029] As Figure 6 shown, the clamping mechanism 6 includes a fixing plate 601 fixed to the rotating block 5, a receiving groove 603 is opened in the fixing plate 601, a clamping plate 602 is arranged in the receiving groove 603, one end of the clamping plate 602 inside the receiving groove 603 is fixed to the elastic component 61, and the other end of the clamping plate 602 is clamped with a clamping groove 16 opened on the surface of the first cutter head 7 or the second cutter head 71.

[0030] The above solution can facilitate the operator to replace the cutting head by pulling the clamping plate 602 in the clamping mechanism 6 and using the clamping groove 16 that matches the first cutting head 7 or the second cutting head 71. Especially when using, for example, Figure 5 the first cutting head 7 or the second cutting head 71 with different shapes in it can cut the rubber block into strips or blocks. At the same time, the utility model can also adopt cutting heads of other shapes so as to complete the cutting and use of rubber blocks of different shapes.

[0031] Specifically, as Figure 7 shown, the elastic force assembly 61 includes a sliding groove 6101 opened in the fixed plate 601. A sliding rod 6102 is fixed in the sliding groove 6101. A slider 6104 is slidably arranged on the surface of the sliding rod 6102, and the side surface of the slider 6104 is fixed to the side surface of the clamping plate 602. A spring 6103 is arranged on the surface of the sliding rod 6102, and both ends of the spring 6103 are respectively lapped with the slider 6104 and the inner wall of the sliding groove 6101.

[0032] By adopting the spring 6103 and the slider 6104 in the elastic force assembly 61, they can cooperate with the clamping plate 602 to move. Especially, the elastic force of the spring 6103 can be used to clamp the first cutting head 7 or the second cutting head 71 by the clamping plate 602, avoiding the shaking of the first cutting head 7 or the second cutting head 71, and it is also extremely convenient for the operator to replace different cutting heads.

[0033] Specifically, as Figure 6 shown, the number of the clamping plates 602 is four, and they are evenly distributed at the middle positions around the fixed plate 601. The number of the elastic force assemblies 61 matches that of the clamping plates 602. By setting the matching elastic force assemblies 61 and clamping plates 602, the stretching and shrinking of the clamping plates 602 can be more stable.

[0034] Embodiment 2

[0035] As Figure 1 , Figure 2 and Figure 4 shown, on the basis of Embodiment 1, this embodiment provides another technical solution: a support plate 9 is arranged above the base 1. A substrate 8 is lapped on the surface of the support plate 9, and the central positions of the substrate 8 and the support plate 9 are connected by a rotating shaft 12. Grooves 13 are opened on the opposite surfaces of the substrate 8 and the support plate 9, and balls 14 are arranged in the grooves 13.

[0036] Specifically, as Figure 1 and Figure 2 shown, a limiting groove 10 is opened on the base 1. A pulley 15 is arranged in the limiting groove 10, and the upper part of the pulley 15 is fixed to the bottom end of the support plate 9. Inclined slopes are arranged at the front and rear ends of the limiting groove 10.

[0037] In this embodiment, a rotating shaft 12 and balls 14 are adopted between the support plate 9 and the substrate 8, so that an operator can rotate the angle of the rubber block without replacing the cutting head, which is beneficial to cutting the rubber block, can also achieve inclined cutting, and can avoid direct contact with the cutting head during the working process, reducing accidental injuries. At the same time, slopes are provided at both front and rear ends of the limiting groove 10, which is beneficial to pushing the support plate 9 and the substrate 8 to the top of the base 1.

[0038] Working principle: During use, a staff member places the rubber block to be cut above the substrate 8, pushes the support plate 9 and the substrate 8 to move through the pulley 15, and uses the slopes at both front and rear ends of the limiting groove 10 to push them to the top of the base 1. Then, by pulling the clamping plate 602 in the receiving groove 603 inside the clamping mechanism 6, the first cutting head 7 or the second cutting head 71 to be used and other types of cutting heads are clamped by the clamping plate 602. When stretching the clamping plate 602, the slider 6104 on the side of the clamping plate 602 will also squeeze the spring 6103 on the surface of the sliding rod 6102 to cooperate with the movement of the clamping plate 602. Finally, the hydraulic rod 4 is started by the controller to drive the first cutting head 7 or the second cutting head 71 to move downward to complete the cutting of the rubber block above the substrate 8. When the angle of the rubber block needs to be rotated, the position of the first cutting head 7 or the second cutting head 71 can be rotated by rotating the substrate 8 or using the rotating block 5 above the clamping mechanism 6 for cutting. After cutting is completed, the support plate 9 and the substrate 8 can be pushed down from the base 1.
