Description

Technical Field

[0001] This invention relates to the field of acrylic sheet crushing technology, specifically to an acrylic sheet scrap crushing and recycling device. Background Technology

[0002] Acrylic (polymethyl methacrylate, PMMA) sheets are widely used in advertising signs, lighting fixtures, bathroom products, and architectural decoration due to their excellent light transmittance, weather resistance, and processing performance. During the production and processing of acrylic products (such as cutting, carving, drilling, and hot bending), a large amount of irregularly shaped scraps are generated, including strips, sheets, blocks, and irregularly shaped fragments with curves. To save resources and reduce production costs, these scraps are usually crushed and recycled, and then reused through methods such as melt granulation.

[0003] Currently, the following technical problems are commonly found in crushing and recycling equipment for plastic scraps:

[0004] First, acrylic scraps exhibit significant anisotropy (for example, the length of long strips is much greater than their thickness, and the width-to-thickness ratio of sheet-like materials is large). When entering the crushing chamber, they are very prone to interlocking and overlapping, forming stable "arch bridges" or "bird's nest" bridging structures. Existing crusher feed inlets lack active intervention mechanisms, and relying solely on gravity or simple stirring devices is insufficient to effectively break up these bridging structures. This results in material being suspended in mid-air and interrupted feeding, requiring frequent machine shutdowns for manual unblocking. This severely reduces recycling efficiency and the level of equipment automation, while also posing certain safety hazards.

[0005] Secondly, many devices attempt to achieve the target particle size in one go using single-stage crushing, resulting in "over-crushing" which generates a large amount of fine dust (increasing the burden of subsequent dust removal) or "under-crushing" which leaves behind excessively large particles (affecting the uniformity of melt granulation). Meanwhile, some devices that use multi-stage crushing methods are prone to increased energy consumption and poor synchronization due to power dispersion.

[0006] Therefore, in order to solve the above problems, a device for crushing and recycling acrylic sheet scraps is proposed. Summary of the Invention

[0030] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. The various embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0031] Example 1

[0032] Please see Figures 1 to 10The present invention preferably provides a technical solution: an acrylic sheet scrap crushing and recycling device, comprising: a frame, and a primary crushing component 06 and a secondary crushing component 07 arranged sequentially from top to bottom within the frame. The primary crushing component 06 includes a cam drive frame disposed on the inner wall of the frame and mounted opposite to each other, and a spike roller structure mounted with each cam drive frame. When the two sets of cam drive frames are relatively close or far apart, the gap between the two sets of spike roller structures is adjusted to achieve dynamic initial crushing of the acrylic sheet scrap. The secondary crushing component 07 is placed below the primary crushing component 06 and is used for crushing the acrylic sheet scrap. A meshing belt drive mechanism is disposed on the outer wall of the frame to drive the primary crushing component 06 and the secondary crushing component 07 to operate simultaneously. The device also includes an arch-breaking roller assembly 03 disposed on the primary crushing component 06, which can move the acrylic sheet scrap from multiple directions to destroy its anisotropic bridging structure.

[0033] This application is as follows Figure 2 , 5 As shown in Figures 6, 7, and 8, the frame is equipped with an arch-breaking roller assembly 03, a primary crushing assembly 06, and a secondary crushing assembly 07 from top to bottom. The arch-breaking roller assembly 03 can actively move acrylic scraps from multiple directions, effectively breaking the "bridging" or "overlapping" structure formed by the anisotropy of sheet or strip materials. This not only prevents materials from being suspended or piled up above the feed inlet or the primary crushing zone, avoiding downtime for cleaning due to blockage, but also ensures that materials enter the crushing zone evenly and stably, greatly improving the reliability of the equipment for long-term continuous operation. At the same time, the arch-breaking roller assembly 03 ensures continuous feeding, preventing the primary crushing assembly 06 and the secondary crushing assembly 07 from running idle or overloaded, further improving energy utilization efficiency.

[0034] The primary crushing component 06 and the secondary crushing component 07 are configured as follows:

[0035] Firstly, a graded crushing strategy of "coarse crushing (primary) + fine crushing (secondary)" is adopted. On the one hand, this avoids directly processing large pieces of material with high-energy-consuming fine crushing mechanisms. Specifically, large scraps are first coarsely crushed into medium-sized flakes by a low-energy-consuming bayonet roller structure before entering the secondary crushing component 07 for efficient crushing. The overall energy consumption curve is flatter, thereby optimizing energy utilization and reducing crushing energy consumption. On the other hand, the adjustable gap primary crushing component 06 can pre-treat the scraps into relatively uniform-sized flakes, providing ideal feeding conditions for the secondary crushing component 07. The secondary crushing component 07 then performs fine crushing on this basis, which can effectively reduce the phenomena of "over-crushing" (generating too much dust) or "under-crushing" (having excessively large particles). The final acrylic recycled particles have a more concentrated particle size distribution, which is conducive to subsequent melting, granulation or direct reuse, and improves the commercial value of recycled materials.

[0036] Secondly, the cam transmission frame is used to drive the bayonet roller structure and achieve dynamic gap adjustment, which further prevents the accumulation of scraps and achieves efficient and reasonable dynamic initial crushing.

[0037] The meshing belt drive mechanism set between the primary crushing component 06 and the secondary crushing component 07 can drive the primary crushing component 06 and the secondary crushing component 07 to run simultaneously. Only one power source is needed to realize the linkage of the crushing system. This not only saves the additional costs brought by multiple motors, multiple reducers and complex electronic control synchronization systems, but also reduces the number of failure points, simplifies the transmission system, and ensures the synchronization of the movement of each component and the speed ratio matching.

[0038] Example 2

[0039] In another embodiment of the present invention, the frame includes a base 01, a housing 02 fixed to the top of the base 01, and guide plates 04 symmetrically arranged in the middle of the housing 02, with a conical channel formed between the two guide plates 04 and a discharge port 05 formed at the bottom of the two.

[0040] like Figure 7 , 8 As shown, in this embodiment, two guide plates 04 are symmetrically fixed in the middle of the housing 02 and form a conical channel. When the scrap material is poured into the conical channel, the arch-breaking roller assembly 03, the primary crushing assembly 06 and the secondary crushing assembly 07 inside the conical channel can process the acrylic sheet scrap material step by step and discharge it through the outlet 05.

[0041] Furthermore, each bayonet roller structure includes two grooves internally disposed on the bottom side of one side of the housing 02, a slider slidably mounted with each groove, and a spring disposed between the slider and the groove; it also includes a slide plate 061 fixed to the top of each slider, with one end of each slide plate 061 extending into a tapered channel between two guide plates 04 and rotatably mounted with a first rotating shaft 062; and a first crushing roller 063 fixed on the first rotating shaft 062.

[0042] Furthermore, each cam drive frame includes a connecting plate fixed in the middle of two slide plates 061, with two mounting plates 0616 disposed in the middle of the connecting plate; and a drive wheel 0617 rotatably mounted between the two mounting plates 0616 via a rotating shaft; it also includes two fixing plates 0612 disposed on the bottom side of one side of the chassis 02, and a drive shaft 0613 rotatably mounted between the two fixing plates 0612, with a cam body 0615 disposed in the middle of the drive shaft 0613, the protruding end of the cam body 0615 being able to contact the drive wheel 0617.

[0043] like Figure 2 , 3As shown in Figure 10, two sliding plates 061 at both ends of one side of the chassis 02 have one end extending into a conical channel and equipped with a first rotating shaft 062. A first crushing roller 063 is fixed on the first rotating shaft 062, and a transmission wheel 0617 in the middle of the roller intermittently contacts the cam body 0615 on the transmission shaft 0613. When the belt drive mechanism is running, as shown in Figure 10, the first crushing roller 063 is fixed on the first rotating shaft 062. Figure 3 , 10 As shown, on the one hand, the first crushing roller 063 is rotated, and on the other hand, the convex end of the cam body 0615 is in contact with the transmission wheel 0617. At this time, the transmission wheel 0617 can push the first crushing roller 063 closer to the center of the conical channel. Conversely, when the concave end of the cam body 0615 is close to the transmission wheel 0617, the transmission wheel 0617 is adaptively reset and moved outward to realize the flexible adjustment of the distance between the two first crushing rollers 063 and realize the dynamic crushing process of the device.

[0044] Example 3

[0045] In another embodiment of the present invention, the secondary crushing assembly 07 includes two second rotating shafts 071 rotatably mounted on the housing 02, wherein the two second rotating shafts 071 are located at the lower part of the two guide plates 04 and near the discharge port 05; and a second crushing roller 072 fixed on each of the second rotating shafts 071.

[0046] Furthermore, the meshing belt drive mechanism includes drive gears 073 and first drive wheels 074 fixed sequentially from the inside to the outside at one end of each second rotating shaft 071, wherein the two drive gears 073 mesh with each other; and a second drive wheel 075 fixed to one end of each transmission shaft 0613 near the first drive wheel 074, and a drive belt 076 is sleeved between the second drive wheel 075 and the first drive wheel 074 distributed on the same side; it also includes a drive motor 077 disposed on the outer wall of the housing 02, the output shaft of the drive motor 077 being fixedly connected to one of the first drive wheels 074; and the transmission shaft 0613 and the first rotating shaft 062 being away from the second drive wheel 075. The end is also fixed with a second transmission gear 0610 and a fourth gear 0614 respectively; and a mounting block 064 is set on the bottom surface of one side of the chassis 02. The mounting block 064 is rotatably mounted with an optical shaft 065 and a spline shaft 066 that are fixed to each other. The optical shaft 065 is fixed with a third gear 0611 that meshes with the fourth gear 0614. The spline shaft 066 is splinedly connected to a spline sleeve 067 and a connecting sleeve 068 fixed on the outer periphery of the spline sleeve 067. The connecting sleeve 068 is connected to a slide plate 061 distributed on the same side. It also includes a first transmission gear 069 set on the spline sleeve 067, and the first transmission gear 069 meshes with the second transmission gear 0610.

[0047] This implementation example Figure 3 , 10As shown, one end of the drive shaft 0613 is connected to the second drive wheel 075, and the other end is fixed with the fourth gear 0614. The middle part is fixed with the cam body 0615. Therefore, when the drive motor 077 is running, on the one hand, the two second crushing rollers 072 are rotated relative to each other to achieve a secondary crushing effect; on the other hand, through the transmission action of the two drive belts 076, the two drive shafts 0613 are further rotated relative to each other. At this time, because the fourth gear 0614, the third gear 0611, the first transmission gear 069, and the second transmission gear 0610 mesh with each other, the two first crushing rollers 063 are rotated synchronously and in opposite directions to achieve a primary crushing effect.

[0048] Furthermore, since the relative rotation of the two first crushing rollers 063 can simultaneously realize the process of the two first crushing rollers 063 moving closer or further away from each other, the dynamic effect of primary crushing is further realized.

[0049] Example 4

[0050] In another embodiment of the present invention, the number of anti-bridging roller assemblies 03 is two and symmetrically assembled on two bayonet roller structures; each anti-bridging roller assembly 03 includes an assembly base 031 fixed to the top of one of the slide plates 061, a vertical plate 032 fixed on the assembly base 031, and a transmission frame 0311 spanning the two slide plates 061, with a first pin 033 and a second pin respectively disposed at both ends of the transmission frame 0311, wherein the inner end of the first pin 033 passes through a through groove opened in the vertical plate 032, and a tripod 0 is fixed to the opposite ends of the first pin 033 and the second pin respectively. 34; and assembly roller 035, which has equidistant breaking teeth 0351 on its outer periphery, and has several assembly holes 036 at both ends. Several swing rods 037 are staggered between the several assembly holes 036 and the tripod 034 distributed on the same side; it also includes a first motor 0314 mounted on the assembly base 031, and the output shaft of the first motor 0314 is fixedly connected to the first pin 033. When the first motor 0314 runs, it is used to drive the assembly roller 035 to rotate; the assembly base 031 is also provided with a worm gear structure to drive the assembly roller 035 to swing.

[0051] Furthermore, each swing arm 037 consists of a central support rod and two end rods installed at both ends of the support rod and distributed symmetrically at the center.

[0052] Furthermore, the worm gear structure includes a vertical plate 038 mounted on the mounting base 031, on which a second motor 039 is mounted; and a worm body 0310 connected to the output shaft of the second motor 039; and also includes an external tooth 0313 mounted on the transmission frame 0311 near the end of the first pin 033, and the external tooth 0313 meshes with the worm body 0310.

[0053] like Figure 3 , 4 As shown in Figures 5 and 9, it is known that the transmission frame 0311 has a tripod 034 rotatably mounted at both ends via a first pin 033 and a second pin, respectively. The two tripods 034 are connected to the assembly roller 035 via several swing rods 037. Each swing rod 037 consists of a central support rod and two end rods installed at both ends of the support rod and symmetrically distributed at the center. The two end rods rotate on a pair of assembly holes 036 and the tripod 034 distributed on the same side, respectively. The several swing rods 037 distributed on the same side have different installation depths. Therefore, during the rotation of the first pin 033 driven by the first motor 0314, the rotation process of the assembly roller 035 and its crushing teeth 0351 can be realized, thereby realizing the crushing process of the scrap material.

[0054] Furthermore, the external teeth 0313 at the end of the transmission frame 0311 mesh with the worm body 0310. When the second motor 039 drives the worm body 0310 to rotate, it can drive the external teeth 0313 and the transmission frame 0311 to pitch and deflect. Since the two arch-breaking roller assemblies 03 are symmetrically installed on the frame, the rotation of the two assembly rollers 035 and their relative pitch and deflection can simulate the plucking action and achieve the arch-breaking effect. This design greatly reduces the necessity of manual material feeding and cleaning of bridging, reduces the operator's close contact with the operating crushing mechanism, and improves the safety of use.

[0055] In this invention, unless otherwise explicitly specified and limited, the terms “installation,” “connection,” “linking,” “fixing,” etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part. There are various ways to install detachably, such as by using a plug-in and snap-fit ​​method, or by using a bolt connection, etc.

[0056] The above embodiments, which describe the specific features of the present invention, are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-essential improvements and adjustments made to the present invention by those skilled in the art based on the above description of the invention fall within the scope of protection of the present invention.
