Description

Technical Field

[0001] This utility model relates to the technical field of rosin crushing equipment, and in particular to a rosin hydraulic crusher. Background Technology

[0002] In the rosin production industry, large pieces of raw rosin must first be effectively crushed before entering subsequent processes. Currently, toothed roller crushers are commonly used in the industry to crush rosin lumps. The specific operation involves first separating the rosin from the packaging barrels using manual tools and simple machinery. Then, the rosin lumps are fed into the toothed roller crusher, where the high-speed rotating toothed rollers subject them to intense impact and compression, breaking them into small particles.

[0003] However, existing toothed roller crushing technology has the following drawbacks in practical applications: First, when separating rosin barrels and rosin, workers need to use tools and simple machinery, resulting in low efficiency and requiring personnel assistance, which poses a safety hazard. Second, due to the high rotation speed of the toothed rollers, a large amount of dust is easily generated during the rosin crushing process, requiring high-power dust extraction equipment, leading to high energy consumption. Furthermore, rosin dust is flammable, posing a safety risk. Third, this technology requires a high-power motor to drive the toothed rollers, resulting in high energy consumption. If the motor power is insufficient, the rotational torque of the toothed rollers will be insufficient, and jamming may easily occur when encountering large pieces of rosin, leading to motor overload. Finally, the toothed roller crushing operation site generates significant noise. Utility Model Content

[0004] The purpose of this invention is to provide a rosin hydraulic crusher that can solve the problems of low production efficiency, low safety, high energy consumption and easy overload, as well as serious noise pollution in existing rosin crushing equipment.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: This rosin hydraulic crusher includes a frame and a crushing box fixed on the frame. One end of the crushing box is provided with a hydraulic extrusion mechanism, and the other end is provided with a rotating clamping mechanism. The hydraulic extrusion mechanism includes a hydraulic cylinder and a first extrusion component connected to the piston rod of the hydraulic cylinder. The rotating clamping mechanism includes a drive motor and a second extrusion component, and the output shaft of the drive motor is connected to the second extrusion component. The first extrusion component and the second extrusion component are coaxially arranged opposite each other in the crushing box, and a material drop frame for supporting the rosin barrel is provided between the first extrusion component and the second extrusion component.

[0006] In the above-mentioned technical solution for the rosin hydraulic crusher, a more specific technical solution may be: the first extrusion component and / or the second extrusion component is an extrusion plate.

[0007] In some possible implementations, the surface of the extrusion plate is provided with protruding teeth.

[0008] In some possible implementations, the crushing chamber has a feed inlet on its side, and a feed curtain is installed at the feed inlet.

[0009] In some possible implementations, the feeding rack has a support beam and limiting rods, with multiple limiting rods provided on the side of the support beam away from the feed inlet.

[0010] In some possible implementations, the crushing box has a barrel opening at the top, and the crushing box is fixed with a top cover back plate, which is hinged to a top cover for opening and closing the barrel opening.

[0011] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: 1. A hydraulic extrusion mechanism provides significant and controllable static pressure, eliminating the need for pre-separation of rosin and rosin barrels. Both can be crushed together, greatly improving production efficiency and eliminating the safety risks associated with manual separation. The drive motor of the rotary clamping mechanism only needs to rotate the rosin barrel, resulting in a much lower load than traditional crushers that use high-speed toothed rollers to crush large, hard objects, significantly reducing motor power. The entire crushing process involves slow extrusion and rotation, rather than high-speed impact and shearing, resulting in extremely low noise. The slow movement also avoids the generation of large amounts of dust from violent impacts, minimizing dust generation. Operators can push the rosin barrel into the crushing chamber while the equipment is stationary and then start the crushing process from a safe distance, avoiding the risks associated with close-range feeding required in traditional equipment. The discharge rack provides a clear placement position for the rosin barrel, ensuring its axis is coaxial with the two extrusion components.

[0012] 2. The extrusion plate design can evenly apply the force of the hydraulic cylinder or motor to the entire end face of the rosin barrel, ensuring that the barrel body is stably and completely crushed, rather than partially punctured, which helps to completely and efficiently extrude the rosin from the barrel; the extrusion plate has a robust structure, low manufacturing and maintenance costs, and can withstand huge pressure without being easily damaged.

[0013] 3. The extrusion plate is equipped with protruding teeth that can be embedded in the rosin barrel skin and rosin to prevent slippage during rotation and ensure the reliability of rotation clamping.

[0014] 4. A feed inlet is provided on the side of the crushing box to facilitate operators in rolling or pushing rosin barrels into the crushing box; the design of the feed curtain allows materials to pass through while closing the feed inlet during equipment operation, effectively preventing the small amount of dust and noise generated during the crushing process from spreading out of the feed inlet, improving the cleanliness and quietness of the working environment. At the same time, because the dust is confined in a relatively enclosed space, the efficiency of the exhaust dust removal equipment is higher.

[0015] 5. The material feeding frame is equipped with a limit rod to prevent the rosin barrel from sliding off the material feeding frame, thus ensuring the stability and reliability of the extrusion process.

[0016] 6. A barrel retrieval opening is provided on the crushing box for cleaning waste rosin barrels or performing internal maintenance on the equipment; the hinged top cover can form a good seal with the crushing box when closed, further enhancing the dust suppression and noise reduction effect.

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments: Figure 1 The rosin hydraulic crusher shown mainly consists of a frame 13, a crushing box 14, a hydraulic extrusion mechanism, and a rotating clamping mechanism. The crushing box 14 is fixed to the frame 13. The hydraulic extrusion mechanism is located at one end of the crushing box 14, and the rotating clamping mechanism is located at the opposite end. The hydraulic extrusion mechanism includes a hydraulic cylinder 10, a hydraulic rod 9 (i.e., the hydraulic cylinder piston rod), and a first extrusion plate 8 located at the front end of the hydraulic rod 9. The first extrusion plate 8 is rotatably connected to the hydraulic rod 9. The hydraulic cylinder 10 is connected to a hydraulic oil pump 12 via a hydraulic oil pipe 11, forming a complete hydraulic power system. The rotating clamping mechanism includes a motor 1, a gearbox 2 connected to the output end of the motor 1, and a second extrusion plate 3 supported on the frame 13 by bearings. The first extrusion plate 8 and the second extrusion plate 3 are coaxially arranged opposite each other within the crushing box 14. A material dropper 16 is provided between them to support the rosin barrel to be crushed, ensuring that the rosin barrel can be stably placed between the two extrusion components, thereby achieving efficient and controllable crushing operations under hydraulic action.

[0020] In this embodiment, both the first extrusion plate 8 and the second extrusion plate 3 are equipped with protruding teeth 4. These protruding teeth 4 can embed into the rosin barrel during the extrusion process, effectively preventing the rosin barrel from slipping during rotation and ensuring the reliability of clamping and rotation. Preferably, the protruding teeth 4 are steel teeth to ensure sufficient hardness to penetrate the rosin barrel. The crushing box 14 has an inlet on its side and is equipped with an inlet curtain 7, which facilitates the operator to push the rosin barrel into the crushing box 14, and effectively seals the space during operation to suppress dust and noise leakage. The discharge rack 16 includes a support beam 16-1 and multiple limiting rods 16-2 on one side of it, which are used to quickly position the rosin barrel and prevent the rosin barrel from slipping during the extrusion process, ensuring the stability and safety of the operation. It is worth mentioning that the support beam 16-1 is composed of at least two or fewer crossbeams as needed; the limiting rods 16-2 are located on the side away from the inlet. In addition, the top of the crushing box 14 is provided with a barrel opening, which can be opened and closed by the upper cover 5 hinged to the upper cover back plate 6, making it convenient to clean the crushed rosin barrel fragments and perform equipment maintenance; the lower part of the crushing box 14 is provided with a hopper 15, which narrows to form a discharge port.

[0021] During operation, the operator first pushes the rosin-filled barrel into the crushing box 14 through the side inlet and places it on the discharge rack 16, aligning the barrel's axis with the two extrusion components. Then, the hydraulic pump 12 is started, supplying oil to the hydraulic cylinder 10 via the hydraulic pipe 11. This causes the hydraulic rod 9 to push the first extrusion plate 8 towards the rosin barrel until the protrusions 4 on the second extrusion plate 3 and the first extrusion plate 8 are inserted into both ends of the rosin barrel. Next, the motor 1 is started, and after deceleration and torque amplification via the gearbox 2, it drives the second extrusion plate 3, the rosin barrel, and the first extrusion plate 8 to rotate. Rotation stops when the seam of the rosin barrel reaches the bottom. The hydraulic cylinder 10 is then controlled to push the first extrusion plate 8 forward again, causing the rosin barrel to crack along the seam. Subsequently, by controlling the motor 1 to rotate forward and reverse, the rosin barrel rotates accordingly, and the rosin falls out from the crack under gravity, achieving separation of the rosin from the barrel. Throughout the process, the operator can complete the loading while the equipment is stationary and operate from a safe distance, significantly improving operational safety.

[0022] This invention achieves complete crushing of packaged rosin barrels by combining hydraulic extrusion and rotary clamping, eliminating the need for pre-separation of the rosin barrels and rosin, significantly improving production efficiency and reducing manual operation risks. The stable and controllable static pressure provided by the hydraulic system avoids the high noise and large amount of dust generated by traditional high-speed crushing methods, improving the working environment and reducing reliance on high-power motors, resulting in a significant reduction in overall energy consumption. Furthermore, the enclosed crushing chamber structure, combined with the feed curtain and top cover design, further enhances the dust suppression and noise reduction effects of the equipment, improving the efficiency of the dust removal system and ensuring the health and safety of operators.
