Description

Technical Field

[0001] The utility model relates to the field of thermoplastic rubber particle processing, in particular to a thermoplastic rubber particle molding device. Background Art

[0002] Thermoplastic rubber granules are a kind of material, usually mixed with rubber granules and thermoplastic resins. These granules are plastic and processable. When producing thermoplastic rubber, they usually need to be stored and transported in granular form. When in use, these granules are shaped by a thermoplastic machine. The granule forming device currently commonly used in the production of thermoplastic rubber usually uses a blade to cut the molded rubber and cut the rubber strips into small granules. The cut rubber granules will be transported to the collection box through the line.

[0003] After searching, Chinese patent announcement number: CN218948144U discloses a thermoplastic rubber particle forming device, including a support platform, a support frame, a telescopic rod, a connecting rod and a first knife holder, the support platform is installed with a support frame on the top, the support frame is installed with a telescopic rod, the bottom of the telescopic rod is installed with a connecting rod, the right end of the connecting rod is installed with a first knife holder, the bottom surface of the first knife holder is provided with a set cutting edge, the set cutting edges are evenly distributed, and the inside of the set cutting edges is installed with a first forming blade, and the first forming blade is inserted into the set cutting edge from bottom to top. The thermoplastic rubber particle forming device is provided with a first knife holder and a second knife holder, and the second forming blade on the second knife holder can be used to cut the strip of thermoplastic rubber to a fixed length, and the thermoplastic rubber after the fixed length can be divided again with the cooperation of the multiple first forming blades on the first knife holder, so that the thermoplastic rubber is formed into particles of uniform length, thereby improving the forming effect of the device.

[0004] In the above technology, although the structure designed by it has certain improvements, it still has certain defects.

A groove 37 is provided on the inner wall of the top of the supporting shell 36, and a through groove 310 is provided on the lower surface of the supporting shell 36. The inner wall of the groove 37 is rotatably connected to a rotating rod 39, and an arc plate 35 is fixedly connected to the rear surface of the rotating rod 39. The arc plate 35 has a certain curvature to ensure that the particles can smoothly fall into the inner wall of the collecting box 41, and the left end of the arc plate 35 contacts the lower surface of the cutting device 1.

[0033] Reference Figure 1 , Figure 3 The material taking component 4 includes a collecting box 41, which slides on the inner wall of the supporting shell 36. A moving wheel 47 is provided on the lower surface of the collecting box 41. The collecting box 41 can be moved by the moving wheel 47, which improves the flexibility of the collecting box 41. The moving wheel 47 slides on the inner wall of the through groove 1 310, and a through groove 2 44 is opened on the front surface of the collecting box 41.

[0034] Reference Figure 1 - Figure 2The cleaning assembly 3 also includes a roller 31, which is fixedly connected to the front surface of the drive shaft 2. The lower side of the roller 31 is connected to the roller 2 32 through a belt 33. One end of the belt 33 contacts the inner wall of the roller 1 31, and the other end of the belt 33 contacts the inner wall of the roller 2 32. Through the cooperation between the roller 1 31, the belt 33, and the roller 2 32, the cleaning column 34 is mobilized to rotate. There is no need to install other driving equipment to drive the cleaning column 34 to rotate, which reduces the cost. The rear surface of the roller 2 32 is fixedly connected to the cleaning column 34, which contacts the transmission belt provided on the cutting device 1, and can clean the transmission belt. The contacting part is a rubber scraper to avoid damage to the transmission belt. The cleaning column 34 penetrates and rotates to be connected to the lower side of the right end of the front surface of the cutting device 1 near the drive shaft 2, and the cleaning column 34 contacts the right side of the lower surface of the cutting device 1 near the arc plate 35.

[0035] Reference Figure 4 A torsion spring 38 is sleeved on the outer wall of the rotating rod 39. The torsion spring 38 is a prior art. It keeps the right end of the arc plate 35 in contact with the cutting device 1 at all times through its own elasticity, thereby improving the cleaning effect. One end of the torsion spring 38 is fixedly connected to the inner wall of the groove 37, and the other end of the torsion spring 38 is fixedly connected to the front surface of the right end of the arc plate 35.

[0036] Reference Figure 2 , Figure 5 The inner wall of the right end of the collection box 41 is elastically connected to a card plate 46 through a spring 45. The spring 45 always pushes the card plate 46 to move to the left through its own elasticity to ensure the stability of the limit. The card plate 46 slides on the inner wall of the right end of the collection box 41. One end of the spring 45 is fixedly connected to the inner wall of the right end of the collection box 41, and the other end of the spring 45 is fixedly connected to the rear surface of the card plate 46. A rectangular groove 311 is opened at the right end of the inner wall of the support shell 36, and the front end of the card plate 46 contacts the inner wall of the rectangular groove 311.

[0037] Reference Figure 2 , Figure 5 A rectangular block 43 is fixedly connected to the rear end of the right surface of the card plate 46, and the rectangular block 43 is slidably connected to the inner wall of the through groove 44. A handle 42 is fixedly connected to the right end of the upper surface of the rectangular block 43. The card plate 46 is arranged in a trapezoidal shape, and the front surface is arranged as an inclined surface. The inclined surface improves the efficiency of fixing the collection box 41.

[0038] Working principle: When in use, the cut products will be sent into the interior of the collecting box 41 through the conveyor belt arranged on the cutting device 1, and at the same time, the driving shaft 2 is rotated to drive the roller 1 31 to rotate, and the roller 1 31 will drive the roller 2 32 to rotate through the belt 33, and the roller 2 32 will drive the cleaning column 34 to rotate. The rotating cleaning column 34 will clean the conveyor belt and clean up the particles adhering to the conveyor belt. The cleaned particles will fall on the upper surface of the arc plate 35 and fall into the interior of the collecting box 41 along the arc surface of the arc plate 35. In this process, the arc plate 35 will be tightly attached to the conveyor belt through the elasticity of the torsion spring 38, thereby improving the cleaning effect.

[0039] When the collected particles need to be pulled out, it is only necessary to hold the handle 42 and push the rectangular block 43 to move through the handle 42. The rectangular block 43 will drive the card plate 46 to move, and the card plate 46 will squeeze the spring 45 until the card plate 46 is completely separated from the inner wall of the rectangular groove 311. At this time, the collection box 41 can be pulled, and the collection box 41 will be moved out of the inner wall of the support shell 36 through the moving wheel 47. In this way, the completed rubber particles can be processed. When installing, it is only necessary to push the collection box 41 into the inner wall of the support shell 36 , and the moving wheel 47 rolls into the inner wall of the through groove 310 until the card plate 46 contacts the support shell 36. The support shell 36 pushes the card plate 46 along the inclined surface of the card plate 46 to move the card plate 46 to the inner wall of the collection box 41. At the same time, the card plate 46 will squeeze the spring 45 until the card plate 46 completely overlaps with the rectangular groove 311. At this time, the spring 45 will push the card plate 46 to move in the opposite direction through its own elasticity, so that the card plate 46 is inserted into the inner wall of the rectangular groove 311, so that the collection box 41 can be fixed.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
