Description

Technical Field

[0001] The invention relates to the technical field of granular material crushing, and in particular to an assembled granular material crushing device and a crushing method for plastic processing. Background Art

[0002] The pellet crushing equipment is a device that crushes the plastic granules to make the crushed plastic easier to process later.

[0003] The existing pellet crushing equipment for plastic processing needs to be transported to a designated location when in use. Firstly, due to the overall height of the pellet crushing equipment for plastic processing being relatively high and the fact that the pellet crushing equipment for plastic processing cannot be disassembled as a whole, the pellet crushing equipment for plastic processing cannot be loaded and transported, which increases the difficulty of transporting the pellet crushing equipment for plastic processing. Secondly, the existing crushing only crushes the pellets once, which easily causes uneven crushing. It is necessary to manually pour the crushed pellets into the crusher again for repeated crushing in order to achieve uniform crushing, which reduces work efficiency and affects the quality of crushing. Finally, the position of the crushing blades in the existing crushing equipment is fixed, and the pellets splashed in the corners cannot be crushed, resulting in waste of pellets. In addition, it is necessary to manually clean the residual pellets in the crushing equipment, which increases the work steps. Summary of the invention

[0004] Based on the technical problems that the existing pulverizing equipment for crushing plastic pellets is too large, causing transportation difficulties, the existing crushing equipment only crushes the pellets once, which easily causes uneven crushing, reduces work efficiency, and affects the crushing quality, the crushing blades in the existing crushing equipment are fixed in position, and the pellets in the corners cannot be crushed, resulting in waste of pellets and increasing the number of working steps, the present invention proposes an assembled pellet crushing equipment and crushing method for plastic processing.

[0005] The present invention provides an assembled granular material crushing device for plastic processing, which comprises a multi-stage telescopic shell, and also comprises a feeding device, a telescopic device and a crushing device installed in the multi-stage telescopic shell.

[0006] The multi-stage telescopic shell is composed of a first shell, a second shell and a third shell which are slidably plugged in sequence.

[0007] The unloading device is located on the outer surface of the multi-stage telescopic shell, and automatically unloads the granular materials that need to be crushed. The unloading device includes an unloading dividing plate, and the unloading dividing plate holds the granular materials that need to be crushed.

[0008] The telescopic device is located on the outer surface of the multi-stage telescopic shell and lifts the multi-stage telescopic shell. The telescopic device includes an adjusting screw rod. The rotation of the adjusting screw rod drives the first shell and the second shell of the multi-stage telescopic shell to lift and lower.

[0009] The crushing device is located on the outer surface of the telescopic shell, and crushes the granular materials to be crushed. The crushing device also includes a crushing mechanism and a moving mechanism. The crushing mechanism includes a crushing knife roller, and the rotation of the crushing knife roller crushes the granular materials. The moving mechanism includes a driving frame, and the movement of the driving frame drives the two crushing knife rollers to move relative or oppositely.

[0010] Preferably, the unloading device also includes a support plate, which is fixedly mounted on the upper surface of the first shell of the multi-stage telescopic shell. A support connecting rod is hinged on the upper side of the support plate through a pin. One end of the support connecting rod is hinged to the outer surface of the unloading plate through a pin. A plurality of the unloading plates are distributed in a circular array to form a unloading hopper.

[0011] Through the above technical scheme, the feed hopper surrounded by the feed dividing plates can hold the plastic pellets that need to be crushed. At the same time, after the multiple feed dividing plates are deflected, they can be close to the support plate, thereby reducing the height of the crushing equipment and facilitating the transportation of the crushing equipment. At the same time, the support plate is fixed to the first shell of the multi-stage telescopic shell by bolts, which is convenient for installation and disassembly, and the support connecting rod facilitates the deflection of the feed dividing plates.

[0012] Preferably, a driving motor is fixedly installed on the outer surface of the first shell of the multi-stage telescopic shell, and a driving worm is rotatably connected to the inner wall of the first shell of the multi-stage telescopic shell through a bearing, and a feeding sleeve with a feeding port is rotatably connected to the lower surface of the support plate through a bearing, and a stirring plate is fixedly installed on one end of the feeding sleeve, and one end of the driving worm drives the rotation of the feeding sleeve through a worm gear, and a rotating sleeve is slidably inserted into the inner wall of the groove of the feeding sleeve through a column, and the outer surface of the rotating sleeve is rotatably connected to the driving plate through a bearing, and one end of the feeding plate is hinged to the outer surface of the driving plate through a pin shaft, and a sealing arc plate is fixedly installed on the upper surface of the rotating sleeve, and the inner surface of the sealing arc plate is slidably connected to the outer side surface of the feeding sleeve.

[0013] Through the above technical scheme, after the driving motor drives the driving worm to rotate, the worm gear can drive the two discharge sleeves to rotate, so that the discharge port on the discharge sleeve is separated from the seal of the sealing arc plate through the rotation of the discharge sleeve, and the discharge sleeve is deflected left and right, which is convenient for indirect discharge and prevents blockage, and facilitates the granular material in the discharge hopper surrounded by the discharge dividing plate to enter the multi-stage telescopic shell through the discharge port. The rotation of the discharge sleeve can drive the stirring plate to rotate, stir the granular material in the discharge hopper, and facilitate discharge. After the discharge sleeve rotates continuously, the column in the rotating sleeve can move in the arc groove of the discharge sleeve, drive the rotating sleeve to rise, and push the driving plate to rise, thereby driving the discharge dividing plate to deflect.

[0014] Preferably, the telescopic device also includes an adjustment plate, which is fixedly mounted on the outer side of the multi-stage telescopic shell, and an adjustment motor is fixedly mounted on the upper surface of the adjustment plate. One end of the output shaft of the adjustment motor is fixedly mounted on one end of the adjusting screw rod through a coupling, and the outer surface of the adjusting screw rod is threadedly connected with a first telescopic sleeve, and the outer surface of the first telescopic sleeve is fixedly mounted on the outer surface of the second shell of the multi-stage telescopic shell through a connecting plate.

[0015] Through the above technical solution, the adjusting motor can drive the adjusting screw to rotate, thereby driving the first telescopic sleeve to rise and fall, thereby driving the second shell on the multi-stage telescopic shell fixedly installed with the first telescopic sleeve to rise and fall, so that after the second shell descends and is located inside the third shell, the height of the multi-stage telescopic shell is reduced.

[0016] Preferably, the inner wall of the first telescopic sleeve is rotatably connected with a threaded sleeve through a bearing, the inner wall of the threaded sleeve is slidably plugged with the outer surface of the adjusting screw rod, the outer surface of the threaded sleeve is threadedly connected with a second telescopic sleeve, the outer surface of the second telescopic sleeve is fixedly installed with the outer surface of the first shell of the multi-stage telescopic shell through a connecting plate, the outer surface of the third shell of the multi-stage telescopic shell is fixedly installed with a limit rod through a support plate, and the outer surfaces of the first and second shells of the multi-stage telescopic shell are slidably plugged with the outer surface of the limit rod.

[0017] Through the above technical solution, the rise of the first telescopic sleeve drives the threaded sleeve to rise, and the threaded sleeve and the adjusting screw are slidably connected and can rotate synchronously, driving the second telescopic sleeve to rise after the threaded sleeve rises, and at the same time, it rises on the rotation of the threaded sleeve, so that the first shell can be driven to cooperate with the second shell to descend, and after further descending, it is located inside the second shell, and the limit rod limits the first shell and the second shell.

[0018] Preferably, the crushing mechanism also includes a sealing plate, and a plurality of the sealing plates are respectively slidably inserted into the first shell and the second shell of the multi-stage telescopic shell, one end of the crushing knife roller is rotatably connected to the outer side surface of the sealing plate through a bearing, and a filter screen is fixedly installed on the inner wall of the telescopic shell, and the lower surfaces of the two filter screens are hinged with guide plates with torsion springs through pin shafts.

[0019] Through the above technical scheme, the sealing plate can facilitate the movement of the crushing knife roller, and at the same time can seal the first shell and the second shell to prevent the leakage of crushed granular materials. The filter screen is convenient for blocking unqualified granular materials and facilitating the passage of qualified granular powder. The shape formed by the deflection of the guide plate facilitates the granular materials to enter between the two crushing knife rollers for crushing, reducing the splashing of granular materials. The torsion spring on the guide plate facilitates the guide plate to maintain the deflected position after resetting, so as to facilitate guiding.

[0020] Preferably, an adjusting rack is fixedly mounted on the upper surface of the adjusting plate, and an adjusting gear is fixedly mounted after one end of the pin shaft of the guide plate passes through the outer side surface of the multi-stage telescopic housing, and the adjusting gear is meshed with the adjusting rack.

[0021] Through the above technical solution, after the first shell and the second shell in the multi-stage telescopic shell are lowered, the adjusting gear is engaged with the adjusting rack, which can drive the guide plate to deflect and approach the filter screen, making it easier for the first shell and the second shell to lower.

[0022] Preferably, the moving mechanism also includes a moving motor, which is fixedly mounted on the outer surface of the multi-stage telescopic shell through a support plate, and one end of the output shaft of the moving motor is fixedly mounted with a rotating rod through a coupling, and a moving frame with a bevel gear is slidably inserted on the outer surface of the rotating rod, and one end of the moving frame is rotatably connected to a double-headed screw through a bearing, and one end of the double-headed screw is meshed with the bevel gear of the moving frame through a bevel gear.

[0023] Through the above technical scheme, the mobile motor can drive the rotating rod to rotate, so that the bevel gear plugged with it on the mobile frame can be rotated, and at the same time, the movement of the mobile frame is not affected. The bevel gear on the double-headed screw is driven by the bevel gear on the mobile frame to rotate, and the double-headed screw is rotated.

[0024] Preferably, one end of the crushing knife roller is rotatably connected to the outer surface of the driving frame through a bearing, the outer surface of the driving frame is rotatably connected to a driving bevel gear, the driving bevel gear is meshed with the bevel gear of the crushing knife roller, the inner wall of the driving bevel gear is slidingly plugged into the outer surface of the double-headed screw rod, the outer surface of the double-headed screw rod is threadedly connected with a threaded sleeve, the outer surface of the driving frame is slidably plugged with a fixed electromagnet with a reset spring, and one end of the fixed electromagnet is magnetically connected to the inner wall of the groove of the threaded sleeve.

[0025] Through the above technical scheme, the rotation of the double-headed screw drives the driving bevel gear to rotate, which can drive the crushing knife roller to rotate. The two crushing knife rollers can rotate synchronously in opposite directions, thereby completing the crushing work. At the same time, the threaded sleeve can be slidably inserted after being magnetically connected to the fixed electromagnet, and the threaded sleeve can be limited. The rotation of the double-headed screw drives the drive frame to move, and at the same time, the double-headed screw drives the driving bevel gear to rotate, thereby driving the two crushing knife rollers to move relative to or oppositely and then rotate, so as to crush the granular materials in other places.

[0026] The present invention provides a crushing method for an assembled pellet crushing device for plastic processing, comprising the following steps:

[0027] S1: Pour the granular materials to be crushed into the discharge hopper surrounded by the discharge dividing plates, and drive the driving motor to rotate after starting. The rotation of the driving worm drives the discharge sleeve to rotate back and forth left and right. The column inside the rotating sleeve rotates in the annular groove of the discharge sleeve, and will not drive the rotating sleeve to rotate. At the same time, the rotation of the discharge sleeve will drive the gap of the sealing plug to be opposite to the feed port of the discharge sleeve. After that, the granular materials in the discharge hopper enter the first shell of the multi-stage telescopic shell through the feed port, the mobile motor is started, and the rotating rod is driven to rotate. The rotating rod drives the bevel gear on the mobile frame to rotate. The bevel gear drives the bevel gear of the double-headed screw that is meshed with it to rotate, so that the driving bevel gear on the double-headed screw rotates synchronously, and then drives the two relative crushing cutter rollers to rotate synchronously in the opposite direction to crush the discharged granular materials;

[0028] S2: The crushed granules are filtered through the filter screen and then crushed between the crushing rollers in the second housing through the guide plate, and then enter between the third crushing rollers through the filter screen and the guide plate for crushing, and then are collected after passing through the filter screen on the third housing. After the crushing is completed, the fixed electromagnet on the drive frame is energized and slidably inserted into the inner wall of the groove of the threaded sleeve. The threaded sleeve drives the drive frame to move under the rotation of the double-headed screw. After the drive frame drives the crushing rollers to move relatively, the granules that have not been crushed on the filter screen are crushed;

[0029] S3: When the crushing equipment needs to be transported, the adjusting motor on the adjusting plate drives the rotation of the adjusting screw rod, driving the first telescopic sleeve to descend while driving the second shell of the multi-stage telescopic shell to descend. At the same time, the descent of the first telescopic sleeve drives the threaded sleeve to descend. At the same time, after the threaded sleeve is slidably plugged with the adjusting screw rod, the threaded sleeve descends and rotates synchronously, driving the second telescopic sleeve to descend, driving the first shell of the multi-stage telescopic shell to descend, and after the first shell and the second shell are descended, the adjusting gear is driven to mesh with the adjusting rack, which can drive the guide plate to deflect inward, so that the first shell and the second shell of the multi-stage telescopic shell can be conveniently descended, thereby reducing the volume occupied by the multi-stage telescopic shell;

[0030] S4: After the driving motor is started by controlling it, it drives the driving worm to rotate, and after the transmission through the worm gear, it drives the unloading sleeve to rotate, so that the column in the rotating sleeve slides along the groove track of the unloading sleeve, drives the rotating sleeve to rise, and the rotating sleeve drives the driving plate to rise, so that the unloading dividing plate hinged to the driving plate is deflected, and then drives the supporting connecting rod to deflect, so that the unloading dividing plate is unfolded, reducing the occupied area.

[0031] The beneficial effects of the present invention are:

[0032] 1. By setting up a feeding device, it is possible to facilitate the feeding of plastic pellets. After the driving motor drives the driving worm to rotate, it drives the feeding sleeve to rotate, so as to drive the stirring plate to stir the pellets in the feeding hopper surrounded by the feeding dividing plate. At the same time, after the feeding sleeve rotates, the feeding port on the feeding sleeve is separated from the seal of the sealing arc plate, and the feeding sleeve is deflected left and right, which is convenient for indirect feeding and prevents blockage. After the continuous rotation of the feeding sleeve, the column in the rotating sleeve can be driven to move in the arc groove on the feeding sleeve, and then the rotating sleeve is driven to rise, so that the driving plate rises and drives the feeding dividing plate to deflect, thereby reducing the height of the crushing equipment, and solving the technical problem that the existing crushing equipment for crushing plastic pellets is too large and causes transportation difficulties.

[0033] 2. By setting up a telescopic device, the height of the multi-stage telescopic shell can be reduced, which is convenient for transportation. By adjusting the drive of the motor, the rotation of the adjusting screw rod can be driven to drive the first telescopic sleeve to descend. The descent of the first telescopic sleeve can drive the threaded sleeve to descend and rotate at the same time, driving the second telescopic sleeve threadedly connected with the threaded sleeve to descend synchronously with the threaded sleeve and continue to descend under the rotation of the threaded sleeve, so that the first shell can be driven to cooperate with the descent of the second shell and be located inside the second shell after further descent, thereby solving the technical problem that the existing crushing equipment for crushing plastic pellets is too large and causes transportation difficulties.

[0034] 3. By setting up a crushing device, the granular materials that need to be crushed can be crushed in multiple stages to increase the crushing effect. The filter screen is used for easy screening, so that qualified granular materials are retained on the filter screen for re-crushing. At the same time, the rotation of the double-headed screw can drive the driving bevel gear to rotate, and then drive the crushing knife roller to rotate to complete the crushing work. After the fixed electromagnet is inserted into the threaded sleeve and the threaded sleeve is limited, the rotation of the double-headed screw can drive the driving frame to move, thereby driving the crushing knife roller connected to the driving frame to move, and the granular materials remaining on the filter screen are crushed, thereby reducing the waste of granular materials. This solves the problem that the existing crushing equipment for crushing plastic granular materials only crushes the granular materials once, which is easy to cause uneven crushing, reduces work efficiency, and affects the quality of crushing. The position of the crushing blade in the existing crushing equipment is fixed, and the granular materials in the corners cannot be crushed, resulting in waste of granular materials and increasing the technical problems of working steps.

Multiple sealing plates 5 are respectively slidably inserted into the first shell and the second shell of the multi-stage telescopic shell 1. One end of the crushing knife roller 51 is rotatably connected to the outer side of the sealing plate 5 through a bearing. The blades on the two opposite crushing knife rollers 51 are staggered. After reducing the generation of gaps, it is convenient to crush the granular materials. In order to screen the crushed granular materials, a filter screen 52 is fixedly installed on the inner wall of the telescopic shell. In order to transport the granular materials between the two crushing knife rollers 51, the lower surfaces of the two filter screens 52 are hinged with a guide plate 53 with a torsion spring through a pin shaft.

[0063] like Figure 1-Figure 13 As shown, the present invention provides a crushing method for an assembled pellet crushing device for plastic processing, comprising the following steps:

[0064] S1: Pour the granular materials to be crushed into the discharge hopper surrounded by the discharge dividing plate 22, and drive the driving motor 3 to rotate after starting. The driving worm 31 drives the discharge sleeve 32 to rotate back and forth, and the column in the rotating sleeve 34 rotates in the annular groove of the discharge sleeve 32, which will not drive the rotating sleeve 34 to rotate. At the same time, the rotation of the discharge sleeve 32 will drive the notch of the sealing plug to be opposite to the feed port of the discharge sleeve 32. After that, the granular materials in the discharge hopper enter the first shell of the multi-stage telescopic shell 1 through the feed port, the mobile motor 6 is started, and the rotating rod 61 is driven to rotate. The rotating rod 61 drives the bevel gear on the mobile frame 62 to rotate. The bevel gear drives the bevel gear of the double-headed screw 63 meshing therewith to rotate, so that the driving bevel gear 65 on the double-headed screw 63 rotates synchronously, and then drives the two relative crushing knife rollers 51 to rotate synchronously in the opposite direction to crush the granular materials discharged;

[0065] S2: The crushed granular material is filtered through the filter screen 52 and then crushed between the crushing rollers 51 in the second housing through the guide plate 53, and then enters between the third crushing rollers 51 through the filter screen 52 and the guide plate 53 for crushing, and then is collected after passing through the filter screen 52 on the third housing. After the crushing is completed, the fixed electromagnet 67 on the drive frame 64 is energized and slidably inserted into the inner wall of the groove of the threaded sleeve 66. The threaded sleeve 66 drives the drive frame 64 to move under the rotation of the double-headed screw 63. After the drive frame 64 drives the crushing rollers 51 to move relatively, the uncrushed granular material on the filter screen 52 is crushed;

[0066] S3: When the crushing equipment needs to be transported, the adjusting motor 41 on the adjusting plate 4 drives the adjusting screw 42 to rotate, driving the first telescopic sleeve 43 to descend while driving the second shell of the multi-stage telescopic shell 1 to descend. At the same time, the descent of the first telescopic sleeve 43 drives the threaded sleeve 44 to descend.
