Description

Technical Field

[0001] The present application relates to the technical field of slitting machines, and in particular to an inner tube cutting device. Background Art

[0002] Rubber inner tube, commonly known as inner tube, refers to a circular elastic tube with a tire valve used to maintain the internal pressure of the tire. The valve is used to inflate and keep the air at a certain pressure in the inner tube. When the rubber inner tube needs to be replaced after long-term use, the replaced inner tube needs to be cut and recycled. At present, the rubber inner tube needs to be cut with a cutting and crushing device when it is recycled. The cut waste rubber inner tube can be used for the production of recycled rubber products.

[0003] For example, the patent with publication number CN106808611A specifically discloses a waste tire slitting and recycling mechanism, which divides the tire into several strips through a strip cutting mechanism, and then sends the preliminarily cut tire strips to the slitting blades of the slitting mechanism through a pulling mechanism, which can cut the waste tire into particles of equal size, which is beneficial to the direct utilization of the tire particles and the next step of crushing the tire particles.

[0004] However, in the above patent, the device divides the tire into several strips through the strip cutting mechanism, which is helpful for the subsequent shredding process. However, when the inner tube is placed in the slitting machine, it is mostly done manually. However, if the worker does not operate it properly, the entry position of the inner tube will be offset. At this time, when the inner tube enters the machine, it is very likely to be entangled on the rotating shafts on both sides of the cutting knife, which may cause the production line to stop running and require shutdown to handle the fault, affecting the production progress and efficiency, resulting in a decrease in production capacity and an increase in production costs. Therefore, it is necessary to provide an inner tube cutting device with a guide device to solve the above problems.

[0005] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0006] Based on the above problems existing in the prior art, the problem to be solved by the present application is: to provide an inner tube cutting device to achieve the effect that the inner tube will not be deflected when entering the slitting machine.

[0007] The technical solution adopted by the present application to solve its technical problems is: an inner tube cutting device, including a base; a slitter, which is arranged on the top of the base, the slitter has a feed end and a discharge end, a cutting cavity is arranged between the feed end and the discharge end, and a cutting knife is arranged in the cutting cavity; a guide assembly, which is arranged at the feed end, the guide assembly includes a mounting frame, the mounting frame is installed on the side of the base close to the feed end, and the mounting frame has two groups of mounting plates; a roller, which is rotatably connected between the two groups of mounting plates; an adjusting rod, which is rotatably connected to the bottom between the two groups of mounting plates, and the adjusting rod is a bidirectional screw; at least two groups of guide plates, and the two groups of guide plates are symmetrically sleeved on the two sections of the thread of the adjusting rod.

[0008] Furthermore, an opening is provided on the guide plate at a position corresponding to the rotating roller, and the size of the opening is adapted to the size of the rotating roller.

[0009] Furthermore, a cover shell is detachably mounted on the top of the cutting chamber, and the cutting knife is suitable for being shielded by the cover shell.

[0010] Furthermore, two groups of guide rods are arranged on both sides of the adjusting rod, and through holes are arranged at the bottom of the guide plate at positions corresponding to the guide rods.

[0011] Furthermore, a protective net is detachably connected to the feed end.

[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0024] like Figure 1-Figure 3 As shown, the present application provides an inner tube cutting device, including a cutting component 1, which is arranged in a tire processing plant and is used to cut and recycle waste inner tubes. Through the cutting component 1, the waste inner tubes can be effectively divided into strips, which is helpful for subsequent recycling and reduces resource waste.

[0025] The cutting assembly 1 includes a base 11, a slitter 2 is fixedly mounted on the top of the base 11, a feed end 21 is provided on one side of the slitter 2, a protective net 211 is detachably connected to the feed end 21, and the protective net 211 is used to prevent debris from entering the slitter 2, and a discharge end 22 is provided on the other side, and a plurality of rollers 221 are provided at the discharge end 22, and the rollers 221 are used for unloading the inner tube after slitting;

[0026] A cutting cavity 24 is provided between the feed end 21 and the discharge end 22, and a plurality of cutters 23 are provided in the cutting cavity 24. The cutters 23 are adapted to rotate at high speed under the drive of an external driving device. When the inner tube is cut, it enters the cutting cavity 24 through the feed end 21, and is cut into strips by the plurality of cutters 23, and then output from the discharge end 22.

[0027] At the same time, a cover shell 25 is detachably mounted on the top of the cutting chamber 24, and the cover shell 25 is used to shield the cutter 23 to prevent external factors from interfering with the cutter 23 and causing safety hazards.

[0028] like Figure 3-Figure 5 As shown, a guide assembly 3 is provided on one side of the base 11 at the feed end 21, and the guide assembly 3 is used to guide the inner tube into the slitting machine 2. The guide assembly 3 includes a mounting frame 31, and the mounting frame 31 is fixedly mounted on the base 11, and the mounting frame 31 has two groups of mounting plates 32, and a plurality of groups of rollers 33 are rotatably connected between the two groups of mounting plates 32, and the rollers 33 are used to contact the inner tube;

[0029] At the same time, an adjusting rod 34 is rotatably installed at the bottom between the two groups of mounting plates 32. The adjusting rod 34 is a bidirectional screw having two symmetrical and oppositely directed threads. At the same time, two groups of guide plates 35 are arranged on the adjusting rod 34, and openings 351 are arranged on the guide plates 35 at positions corresponding to the rollers 33. The size of the openings 351 matches the size of the rollers 33. The two groups of guide plates 35 are symmetrically sleeved on the two sections of the threads of the adjusting rod 34. When the adjusting rod 34 rotates, the two groups of guide plates 35 gradually approach or move away from each other to adapt to inner tubes of different sizes or types.

[0030] At the same time, two sets of guide rods 36 are fixedly installed on both sides of the adjustment rod 34, and through holes are provided at the bottom of the guide plate 35 corresponding to the positions of the guide rods 36. When the guide plate 35 moves driven by the adjustment rod 34, it will slide on the guide rods 36 synchronously, thereby ensuring that the guide plate 35 has a stable guiding structure when moving, which helps to maintain the stability and accuracy of the device.

[0031] At the same time, one end of the adjusting rod 34 passes through one of the mounting plates 32, and a driving motor 4 is fixedly installed on the mounting plate 32. A transmission part 5 is arranged between the driving motor 4 and the adjusting rod 34. The transmission part 5 in this embodiment can be a traditional belt transmission mechanism. When the driving motor 4 is working, it will drive the transmission part 5 to move, thereby driving the adjusting rod 34 to rotate synchronously, and then the distance between the two groups of guide plates 35 is adjusted according to the size of the inner tube.

[0032] When the discarded inner tube needs to be cut, first adjust the distance between the two sets of guide plates 35 according to the model and size of the inner tube, and then put the inner tube into the top of the roller 33. At this time, the inner tube will be restricted by the two sets of guide plates 35 so that it will not deviate to both sides when entering the slitting machine 2.

[0033] In summary, the device sets the guide assembly 3 so that the inner tube is always kept in the correct position during the entire slitting process, avoiding deviation and instability, thereby ensuring the accuracy and stability of the slitting process.

[0034] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
