[0029] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below. In the following description, a large number of specific details are set forth in order to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the scope of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0030] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can be a middle element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there can be a middle element. Conversely, when an element is referred to as being "directly on" another element, there is no middle element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] like Figs. 1 to 3 As shown, a rubber block conveying and feeding system for receiving rubber blocks and a rubber cutter includes:

[0033] Conveying mechanism 1 is used to convey the rubber blocks;

[0034] Glue cutter 3 is used to cut the glue blocks into small pieces and transport them to the production system;

[0035] Transfer structure 2 is used to push the glue block conveyed by the transmission mechanism to the glue cutter 3;

[0036] The control system receives the cutting data from the glue cutter 3, and simultaneously controls the frequency at which the conveying mechanism 1 transmits the glue block to the transfer structure 2, and also controls the frequency at which the transfer structure 2 transmits the glue block to the glue cutter 3.

[0037] The control system controls the intermittent transmission of glue blocks to the glue cutter 3 position, preventing the glue blocks from accumulating at the glue cutter 3 position. During operation, the glue cutter 3 cuts only a preset number of glue blocks, preventing blockage. At the same time, the control system controls the operation of the transmission mechanism, the transfer structure 2, and the glue cutter 3, linking the transmission mechanism and the glue cutter 3 to achieve automatic operation of the production line, thereby improving production efficiency and reducing production costs.

[0038] At this point, the transfer structure is a rubber block turning conveyor, and the control system uses a PLC to control the conveying mechanism, the rubber cutter, and the transfer structure, thereby realizing the linkage between multiple devices.

[0039] To shred the rubber block, a rubber cutter 3 is required. In this embodiment, the rubber cutter 3 includes a cutting body 31, which is equipped with a cutter 32. A motor that drives the cutter 32 to rotate is located on the outside of the cutting body 31. One end of the cutting body 31 has a rubber inlet, and the other end has a rubber outlet. The rubber outlet is equipped with a baffle 4 with a through hole. With the baffle 4 at the rubber outlet and the through hole, after the rubber block enters the rubber cutter 3, it is shredded into rubber particles by the cutter 32 and then exits through the through hole in the baffle 4 to the outside of the rubber cutter 3.

[0040] In order to avoid the rubber particles obtained after cutting from being out of the rubber cutting machine 3, in the embodiment, the rubber cutting body 31 is circular, the rubber outlet is located at the lower side of the rubber cutting body 31, the baffle 4 is arc-shaped, and the rubber cutting body 31 and the inner side of the baffle 4 are circular after being fixed with the rubber cutting body 31. After the baffle 4 is fixed with the rubber cutting body 31, the inner side of the baffle 4 and the rubber cutting body 31 is circular, which does not affect the rotation of the rubber block and the rubber particles in the rubber cutting body 31. When the cutting knife 32 does not rotate or rotates at a low speed, the rubber particles can move to the position of the baffle 4 at the lower side of the rubber cutting body 31 under the action of gravity, and then come out from the through hole of the baffle 4, so that the rubber particles can be avoided to be stuck at the inner side of the rubber cutting body 31 to form the "stuck material" phenomenon.

[0041] Further, in order to cut the rubber block into rubber particles by the cutting knife 32, in the embodiment, the distance between the cutting knife 32 and the inner side of the rubber cutting body 31 is smaller than the designed size of the rubber particles. In order to discharge the rubber particles obtained after cutting from the rubber cutting body 31, in the embodiment, the size of the through hole of the baffle 4 is matched with or slightly larger than the size of the rubber particles, so as to avoid the rubber particles from being blocked at the position of the through hole of the baffle 4.

[0042] In order to link the transmission mechanism and the rubber cutting machine 3, and realize the transmission of the rubber block to the rubber cutting machine 3 after the cutting is completed, in the embodiment, the rubber block conveying and feeding device and the receiving system of the rubber cutting machine 3 further include a detection switch for detecting whether the rubber block is cut to a preset degree. At this time, the preset degree refers to cutting the rubber block into rubber particles with a certain diameter. At this time, the size of the rubber particles can be detected to determine, or the working time of the rubber cutting machine 3 can be preset. When the rubber cutting machine 3 runs for a preset time (for example, 40s / 50s / 60s, etc.), it is determined that the rubber block cutting knife 32 is cut to a preset degree, then the rubber particles in the rubber cutting machine 3 are discharged, and the new rubber block is transmitted to the rubber cutting machine 3 for the next cutting.

[0043] In the embodiment, in order to detect whether the rubber block is cut to the preset degree, specifically, the rubber block is cut to the preset degree, the outer side of the baffle 4 of the glue outlet is provided with a discharge pipe 5, the position of the discharge pipe 5 is provided with a switch plate 6, the switch plate 6 is horizontally arranged or arranged obliquely downward, the switch plate 6 is rotationally connected with the discharge pipe 5, the outer side of the switch plate 6 is provided with a platform extending to the outer side of the discharge pipe 5, the upper side of the platform is provided with a counterweight 7, under the action of the counterweight 7, the switch plate 6 on the inner side of the discharge pipe 5 blocks the discharge pipe 5, when the rubber particles on the upper side of the switch plate 6 increase to the preset weight, the switch plate 6 rotates, the discharge pipe 5 is opened, and the rubber particles come out from the discharge pipe 5. At this time, since the baffle 4 is provided with a plurality of through holes, the rubber block can be cut during the rotation of the cutter 32, and the cut rubber particles can also be discharged from the through holes to the discharge pipe 5. With the operation of the cutter 32, more and more rubber particles enter the discharge pipe 5 from the through holes. These rubber particles in the discharge pipe 5 are all located on the upper side of the switch plate 6. At this time, the middle of the switch plate 6 is provided with a circular hole, a rotating shaft is arranged at the position of the circular hole, the rotating shaft is rotationally connected with the discharge pipe 5. Of course, the side of the discharge pipe 5 is provided with a slot which can accommodate the circular hole. The platform is located on the outer side of the discharge pipe 5. Under the action of the rotating shaft, the switch plate 6 and the platform are similar to a balance structure. Under the action of the counterweight 7, the switch plate 6 blocks the discharge pipe 5.

[0044] When the switch plate 6 is horizontally arranged, the whole switch plate 6 is the same as the cross section of the discharge pipe 5 (the size is slightly smaller than the cross section size of the discharge pipe 5). In order to avoid the switch plate 6 from being upward, a stop block is arranged on the inner wall of the discharge pipe 5, which is located on the horizontal upper side of the switch plate 6, so as to avoid the switch plate 6 from being upward under the action of the counterweight 7.

[0045] When the switch plate 6 is arranged obliquely downward, the switch plate 6 is arranged obliquely at this time. The size of the switch plate 6 is larger than the cross section size of the discharge pipe 5, so that the stop block does not need to be arranged, and the switch plate 6 can also be avoided from being upward.

[0046] The rubber particles cut by the cutter 32 enter the discharge pipe 5 through the through holes and accumulate on the upper side of the switch plate 6. With the action of the cutter 32, more and more rubber particles enter the discharge pipe 5, until the downward force of the rubber particles on the switch plate 6 is greater than the downward force of the counterweight 7 on the platform. In this way, the switch plate 6 rotates downward, so that the rubber particles accumulated on the upper side of the switch plate 6 can be transmitted to the production system. At this time, whether the switch plate 6 rotates can be detected, so as to determine the preset degree of the rubber block cutting. When it is detected that the switch plate 6 rotates, it means that there are more rubber particles accumulated on the upper side of the switch plate 6, that is, the rubber block is cut into pieces or most of the rubber block is cut into pieces. New rubber block can be put into the rubber cutting machine 3, so as to realize the linkage of the rubber cutting machine 3, the transmission mechanism and the transfer structure 2, and automatic operation production.

[0047] Specifically, in order to detect whether the switch plate 6 rotates, in the embodiment, a micro switch is arranged on the upper side of the platform or the outer side of the discharge pipe 5. When the switch plate 6 rotates, the micro switch contacts the discharge pipe 5 or the platform, thereby detecting the rotation of the switch plate 6.

[0048] In different needs, rubber particles of different diameters / sizes may be required, and therefore, in the embodiment, an opening is arranged on the lower side of the rubber cutting body 31, a rubber outlet is formed at the opening position, the rubber outlet is provided with a groove, and the baffle 4 is detachably fixed with the rubber cutting machine 3 through the groove. By detachably arranging the baffle 4 with the rubber cutting machine 3, the baffle 4 with a through hole of different sizes can be adjusted according to actual needs. Meanwhile, by detachably fixing the baffle 4 with the rubber cutting machine 3 through the groove, the baffle 4 can be taken out for cleaning in the case that the through hole of the baffle 4 is blocked, so as to avoid the blockage of the through hole of the baffle 4 and affect the entry of the rubber particles into the discharge pipe 5.

[0049] A control method of a rubber block conveying and feeding and a rubber cutting machine 3 to an accepting system, characterized in that the method comprises:

[0050] S1, starting the transmission mechanism to transmit the rubber block to the transfer structure 2;

[0051] S2, the transfer structure 2 transmits the rubber block to the rubber cutting machine 3;

[0052] S3, the rubber cutting machine 3 is started to shred the rubber block, and after the rubber cutting machine 3 is started, the rotating speed of the cutter 32 alternately runs at a fast speed and a slow speed;

[0053] S4, the shredded rubber particles fall through the through hole of the baffle 4 to the upper side of the switch plate 6, and after the rubber particles on the upper side of the switch plate 6 reach a preset weight, the switch plate 6 is opened, and the rubber particles enter the production system;

[0054] S5, after detecting that the rubber particles enter the production system, steps S1 and S2 are repeated to transmit the rubber block to the rubber cutting machine 3, and then steps S3 and S4 are repeated.

[0055] At this time, in order to ensure that the rubber particles can smoothly enter the discharge pipe 5, in step S3, when the cutter 32 runs fast, the cutter 32 shreds the rubber block, and when the cutter 32 runs slowly, the cutter 32 pushes the rubber particles through the through hole of the baffle 4 to the discharge pipe 5. If the rotating speed of the cutter 32 is always fast, the shredded rubber particles are easy to rotate at high speed in the rubber cutting machine 3, and the rubber particles entering the discharge pipe 5 through the through hole are less. Therefore, the speed of the cutter 32 is reduced, and at this time, the cutter 32 is equivalent to a pushing block for pushing the rubber particles in the rubber cutting machine 3 out of the through hole position, thereby improving the efficiency of the rubber particles entering the discharge pipe 5.

[0056] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, as long as the combination of the technical features does not exist in contradiction, it shall be considered within the scope of the present disclosure.

[0057] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it shall not be understood as a limitation on the patent scope of the present application. It shall be pointed out that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these shall be within the protection scope of the present application. Therefore, the protection scope of the present application patent shall be subject to the appended claims.
