Description

Technical Field

[0001] This invention relates to the field of plastic masterbatch feeding technology, and more specifically, to a plastic semi-finished product masterbatch raw material feeding device. Background Technology

[0002] Plastic semi-finished product masterbatch raw materials are an important component of the plastics processing industry. Masterbatch raw materials are usually made by mixing high-concentration pigments, additives and carrier resins through a specific process. They have many advantages, such as ensuring the uniform dispersion of pigments or additives in plastics, thereby improving the color consistency and performance stability of plastic products.

[0003] The plastic semi-finished product masterbatch raw material feeding device is an important piece of equipment used to accurately and efficiently transport plastic semi-finished product masterbatch raw materials into the processing equipment.

[0004] Existing feeding devices use hoisting equipment to lift the packaging bags containing plastic semi-finished masterbatch raw materials and then transport them into the hopper. During the hoisting process, hooks are typically used to hang the packaging bags by their ropes. When the ropes are hoisted, they form a triangular shape with the hooks, causing the stress point to concentrate at the top of the hooks, which can easily lead to rope breakage and feeding failure. Therefore, we propose a new feeding device for plastic semi-finished masterbatch raw materials. Summary of the Invention

[0005] The purpose of this invention is to provide a feeding device for plastic semi-finished product masterbatch raw materials, so as to solve the technical problem that the hanging rope is easily broken when using a hook to lift the masterbatch raw material packaging bag, resulting in feeding failure.

[0011] The inner bottom surface of the rope channel two is provided with multiple toothed grooves;

[0012] The rope locking assembly includes a fixed frame disposed above the second rope channel. The top surface of the fixed frame is integrally formed with a concave plate, and the side wall of the concave plate is provided with a groove. A rotating block is disposed in the groove of the concave plate, and the rotating block is rotatably connected to the inner side wall of the groove of the concave plate through a rotating shaft.

[0013] A torsion spring is also provided in the groove of the concave plate, and one side wall of the torsion spring is in contact with the side wall of the rotating block.

[0014] The top surface of the concave plate is connected to a support frame, and the top surface of the support frame is provided with a clamping plate and a second torsion spring. The top surface of the support frame is rotatably connected to the clamping plate through the second torsion spring.

[0015] The rotating block has a plurality of toothed blocks on its sidewall that match the toothed groove, and a protrusion is provided on the top surface of the rotating block;

[0016] The bottom surface of the card plate has a groove that matches the protrusion.

[0017] Preferably, the fixing plate has a long strip-shaped structure, and the two ends of the fixing plate are set as arc-shaped structures.

[0018] Preferably, a fixing block is provided inside the rope frame, and the fixing block has a rack channel from top to bottom.

[0019] Preferably, the rack plate is movably connected inside the rope frame via the pull rod.

[0020] Preferably, gear one and gear two are rotatably connected to the inner wall of the pull rope frame, and the support plate is rotatably connected to the inner wall of the pull rope frame through the rotating shaft of gear two.

[0021] Preferably, a masterbatch raw material packaging bag is provided below the feeding component, and a hanging rope is provided on the side wall of the masterbatch raw material packaging bag.

[0022] Preferably, a plurality of hoppers are provided below the fixing frame, and a discharge pipe is provided on the side wall of the hopper.

[0023] Preferably, the sidewall of the card plate is configured as an arc-shaped curved surface structure to facilitate movement along the end of the fixing plate to the top surface of the fixing plate.

[0024] Preferably, the top surface of the first rope channel and the top surface of the second rope channel are mutually complementary arc-shaped curved surface structures.

[0025] Preferably, the method of using the plastic semi-finished product masterbatch raw material feeding device includes the following steps:

[0026] S1. Hanging material: Place the masterbatch material packaging bag containing the plastic semi-finished masterbatch material under the feeding component, and then put the two hanging ropes of the masterbatch material packaging bag into the rope channel one on the top surface of the two rope frames respectively. Then put the hanging ropes extending from both ends of the rope channel one into the rope channel two at the end of the support plate.

[0027] S2. Ascending: The hoisting motor operates, causing the cable to retract and pull the pulley below upward, further driving the feeding assembly upward. During the upward pull of the pulley, the connecting rod moves upward. At this time, the rope frame is pulled by the hanging rope in the rope channel one, causing the rack plate to slide upward, driving gear one to rotate, further driving gear two to rotate, causing the support plate coaxially connected to gear two to rotate until the bottom of the rack plate contacts the top surface inside the rope frame and drives the rope frame to move upward. At this time, the support plate rotates to be flush with rope channel one, tauts the hanging rope, and drives the masterbatch raw material packaging bag to move upward.

[0028] S3. Locking the rope: During the rotation of the support plate toward the rope channel, the arc-shaped curved surface structure of the side wall of the clamping plate moves along the end of the fixed plate to the top surface of the fixed plate, causing the clamping plate to rotate. The groove at the bottom of the clamping plate leaves the protrusion on the top surface of the rotating block. At this time, the rotating block loses the clamping function of the clamping plate and is subjected to the torque of the first torsion spring, causing the rotating block to rotate into the second rope channel. The multiple toothed blocks at the bottom of the rotating block cooperate with the multiple toothed grooves on the bottom surface of the second rope channel to clamp and lock the hanging rope.

[0029] S4. Feeding: The crane works to slide the hoisting frame along the slide rail, which slides the masterbatch raw material packaging bag to the top of the silo. By cutting open the bottom of the masterbatch raw material packaging bag, the plastic semi-finished masterbatch raw material falls into the silo and is discharged into the processing equipment through the discharge pipe.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. This invention utilizes a hoisting motor to retract the cable, pulling the lower pulley upwards, which in turn moves the feeding assembly upwards. During this upward movement, the connecting rod moves upwards as well. At this time, the rope frame is pulled by the rope within the rope channel, causing the rack plate to slide upwards. This drives gear one to rotate, which in turn drives gear two to rotate, causing the support plate coaxially connected to gear two to rotate until the bottom of the rack plate contacts the top surface inside the rope frame, moving the rope frame upwards. At this point, the support plate rotates to the position where it is aligned with the rope channel. The rope is taut and aligned, causing the masterbatch raw material packaging bag to move upwards for loading. The rope frame, in conjunction with two rotating and unfolding support plates, stretches the rope into a square shape, distributing the stress across the frame and support plates. This improves the rope's durability and avoids the triangular shape of traditional lifting methods, where the stress is concentrated at the top, leading to breakage and loading failure of the plastic semi-finished masterbatch raw material. This solves the problem of rope breakage and loading failure when using hooks to lift masterbatch raw material packaging bags.

[0032] 2. In addition, during the rotation of the support plate towards the rope channel, the arc-shaped curved surface structure of the side wall of the clamping plate moves along the end of the fixed plate to the top surface of the fixed plate, causing the clamping plate to rotate. The groove at the bottom of the clamping plate moves away from the protrusion on the top surface of the rotating block. At this time, the rotating block loses the clamping function of the clamping plate and is subjected to the torsion force of the first torsion spring, causing the rotating block to rotate into the second rope channel. The multiple toothed blocks at the bottom of the rotating block cooperate with the multiple toothed grooves on the bottom surface of the second rope channel to clamp and lock the hanging rope. Even if the hanging rope breaks, the hanging rope on the other side, due to the gravity of the masterbatch raw material packaging bag, pulls the multiple toothed blocks of the rotating block to engage and lock the hanging rope with the multiple toothed grooves on the bottom surface of the second rope channel, playing an auxiliary lifting role and preventing the masterbatch raw material packaging bag from falling and causing danger. This further improves the stability and safety of the feeding process and further solves the problem that the hanging rope is easily broken when using a hook to lift the masterbatch raw material packaging bag, resulting in feeding failure.

[0033] 3. The present invention also designs the top surfaces of rope channel one and rope channel two as mutually cooperating arc-shaped curved surface structures, which enables the hanging rope to be more stably attached to the bottom surface in rope channel one and rope channel two, making the force on the hanging rope more uniform, avoiding the risk of concentrated force points and easy breakage of the hanging rope, and further solving the problem that the hanging rope is prone to breakage when using hooks to lift masterbatch raw material packaging bags, resulting in material loading failure.

[0049] like Figures 1 to 8 As shown, the present invention relates to a plastic semi-finished product masterbatch raw material feeding device, including a crane body 1, a feeding component 2 and a rope locking component 3;

[0050] In an embodiment of the present invention, the crane body 1 includes a fixed frame 101, a plurality of slide rails 102 are provided on the top surface of the fixed frame 101, a lifting frame 103 is slidably connected to the top surface of the slide rails 102, a lifting motor 104 is provided on the top surface of the lifting frame 103, and a plurality of pulleys 105 and a sliding cable 106 are provided at the output end of the lifting motor 104.

[0051] Below the feeding component 2, there is a masterbatch raw material packaging bag 401. The side wall of the masterbatch raw material packaging bag 401 is provided with a hanging rope 402. Below the fixing frame 101, there are multiple material bins 501. The side wall of the material bins 501 is provided with a discharge pipe 502.

[0052] The feeding assembly 2 includes a connecting rod 201 located at the bottom of the pulley 105. A pull rod 202 is connected to the bottom of the connecting rod 201. A rope frame 203 passes through the pull rod 202. A fixing plate 205 is connected to the top surface of the rope frame 203. A rope channel 204 is provided on the side wall of the fixing plate 205. A rack plate 206 is connected to the bottom of the pull rod 202. A gear 207 is meshed on one side of the rack plate 206. A gear 208 is meshed at the output end of the gear 207. A support plate 209 is coaxially connected to the gear 208. The same structure is provided on the other side of the rack plate 206. A rope channel 212 is provided at the end of the support plate 209. Multiple tooth grooves 213 are provided on the bottom surface of the rope channel 212. The gear 207 and the gear 208 are rotatably connected to the inner side wall of the rope frame 203. The support plate 209 is rotatably connected to the inner side wall of the rope frame 203 through the rotating shaft of the gear 208.

[0053] In this invention, the hoisting motor 104 operates, causing the sliding cable 106 to retract, pulling the lower pulley 105 upward, further driving the feeding assembly 2 upward. During the upward pulling of the pulley 105, the connecting rod 201 moves upward. At this time, the rope frame 203 is subjected to the tension of the hanging rope 402 in the rope channel 204, causing the rack plate 206 to slide upward, driving the gear 1 207 to rotate, further driving the gear 2 208 to rotate, causing the support plate 209 coaxially connected to the gear 2 208 to rotate, until the bottom of the rack plate 206 contacts the inner top surface of the rope frame 203 and drives the feeding assembly 2 to move upward. As the rope frame 203 moves upward, the support plate 209 rotates to be flush with the rope channel 204, taut the hanging rope 402, and drives the masterbatch raw material packaging bag 401 upward to perform the feeding operation. By using the rope frame 203 in conjunction with the two rotating and unfolding support plates 209, the hanging rope 402 is pulled into a square shape, so that the stress point of the rope is distributed on the rope frame 203 and the two support plates 209, improving the durability of the hanging rope 402 and avoiding the traditional lifting method where the hanging rope 402 is in a triangular state, the stress point is concentrated at the top, which is easy to break and causes the failure of feeding the plastic semi-finished masterbatch raw material.

[0054] In an embodiment of the present invention, the rope locking assembly 3 includes a fixing frame 301 disposed above the rope channel 212. A concave plate 302 is integrally formed on the top surface of the fixing frame 301. A groove is provided on the side wall of the concave plate 302. A rotating block 303 is disposed within the groove of the concave plate 302. The rotating block 303 is rotatably connected to the inner side wall of the groove of the concave plate 302 via a rotating shaft. A torsion spring 304 is also disposed within the groove of the concave plate 302. The side wall of the torsion spring 304 is connected to the rotating block 303 via a rotating shaft. The side walls of block 303 are in contact with each other. The top surface of concave plate 302 is connected to support frame 305. The top surface of support frame 305 is provided with clamping plate 306 and torsion spring 307. The top surface of support frame 305 is rotatably connected to clamping plate 306 through torsion spring 307. The side wall of rotating block 303 is provided with multiple tooth blocks 308 that match tooth groove 213. The top surface of rotating block 303 is provided with protrusion 309. The bottom surface of clamping plate 306 is provided with slots that match protrusion 309.

[0055] During the rotation of the support plate 209 toward the rope channel 204, the arc-shaped curved surface structure of the side wall of the clamping plate 306 moves along the end of the fixing plate 205 to the top surface of the fixing plate 205, causing the clamping plate 306 to rotate. The slot at the bottom of the clamping plate 306 moves away from the protrusion 309 on the top surface of the rotating block 303. At this time, the rotating block 303 loses the clamping effect of the clamping plate 306 and is subjected to the torsion force of the torsion spring 304, causing the rotating block 303 to rotate into the rope channel 212. The multiple teeth at the bottom of the rotating block 303... Block 308 and multiple toothed grooves 213 on the inner bottom surface of rope channel 212 cooperate with each other to clamp and lock the hanging rope 402. Even if the hanging rope 402 breaks, the other side of the hanging rope 402, due to the gravity of the masterbatch raw material packaging bag 401, pulls the multiple toothed blocks 308 of rotating block 303 and multiple toothed grooves on the inner bottom surface of rope channel 212 to lock the hanging rope 402, which plays an auxiliary lifting role, prevents the masterbatch raw material packaging bag 401 from falling and causing danger, and further improves the stability and safety of the feeding process.

[0056] In another embodiment of the present invention, the fixing plate 205 is a long strip-shaped structure with arc-shaped ends. The side wall of the clamping plate 306 is an arc-shaped curved surface structure, which facilitates movement along the end of the fixing plate 205 to the top surface of the fixing plate 205. The rope frame 203 is provided with a fixing block 210. The fixing block 210 has a rack channel 211 from top to bottom. The fixing block 210 enhances the stability of the rope frame 203 structure, and the rack channel 211 increases the movement space of the rack plate 206. The rack plate 206 is movably connected inside the rope frame 203 by the pull rod 202.

[0057] In another embodiment of the present invention, the top surface of rope channel one 204 and the top surface of rope channel two 212 are mutually cooperating arc-shaped curved surface structures. By designing the arc-shaped curved surface structure, the hanging rope 402 can be more stably attached to the bottom surface in rope channel one 204 and rope channel two 212, so that the force on the hanging rope 402 is more uniform, avoiding the risk of concentrated force points and easy breakage of the hanging rope 402.

[0058] Working principle: This embodiment provides a plastic semi-finished product masterbatch raw material feeding device. In use, the masterbatch raw material packaging bag 401 containing the plastic semi-finished product masterbatch raw material is placed below the feeding component 2. Then, the two hanging ropes 402 of the masterbatch raw material packaging bag 401 are respectively looped into the rope channels 204 on the top surface of the two rope frames 203. The hanging ropes 402 extending from both ends of the rope channels 204 are then looped into the rope channels 212 at the end of the support plate 209. The hoisting motor 104 operates, causing the sliding cable 106 to retract, thus feeding the lower part of the masterbatch. The pulley 105 is pulled upwards, further driving the feeding assembly 2 to move upwards. During the upward movement of the pulley 105, the connecting rod 201 is also moved upwards. At this time, the rope frame 203 is pulled by the hanging rope 402 in the rope channel 204, causing the rack plate 206 to slide upwards, driving the gear 207 to rotate, which in turn drives the gear 208 to rotate, causing the support plate 209, which is coaxially connected to the gear 208, to rotate until the bottom of the rack plate 206 contacts the inner top surface of the rope frame 203, driving the rope frame 203 to move upwards. When the support plate 209 rotates to be flush with the rope channel 204, the hanging rope 402 is taut, causing the masterbatch raw material packaging bag 401 to move upward. During the rotation of the support plate 209 towards the rope channel 204, the arc-shaped curved surface structure of the side wall of the clamping plate 306 moves along the end of the fixed plate 205 to the top surface of the fixed plate 205, causing the clamping plate 306 to rotate. The groove at the bottom of the clamping plate 306 moves away from the protrusion 309 on the top surface of the rotating block 303. At this time, the rotating block 303 loses the clamping effect of the clamping plate 306 and is subjected to the torsion spring 304. The torque causes the rotating block 303 to rotate into the rope channel 212. The multiple toothed blocks 308 at the bottom of the rotating block 303 cooperate with the multiple toothed grooves 213 on the bottom surface of the rope channel 212 to clamp and lock the hanging rope 402. Through the operation of the crane body 1, the lifting frame 103 slides along the slide rail 102, and slides the masterbatch raw material packaging bag 401 above the silo 501. By cutting open the bottom of the masterbatch raw material packaging bag 401, the plastic semi-finished masterbatch raw material falls into the silo 501 and is discharged into the processing equipment through the discharge pipe 502.

[0059] The embodiments disclosed in this invention are preferred embodiments, but are not limited thereto. Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.

Locking the rope: During the rotation of the support plate (209) toward the rope channel one (204), the arc-shaped curved surface structure of the side wall of the clamping plate (306) moves along the end of the fixed plate (205) to the top surface of the fixed plate (205), causing the clamping plate (306) to rotate. The slot at the bottom of the clamping plate (306) leaves the protrusion (309) on the top surface of the rotating block (303). At this time, the rotating block (303) loses the clamping function of the clamping plate (306) and is subjected to the torque of the torsion spring one (304), causing the rotating block (303) to rotate into the rope channel two (212). The multiple tooth blocks (308) at the bottom of the rotating block (303) cooperate with the multiple tooth grooves (213) on the bottom surface of the rope channel two (212) to clamp and lock the hanging rope (402). S4. Loading: The crane body (1) operates to make the lifting frame (103) slide along the slide rail (102) to slide the masterbatch raw material packaging bag (401) above the silo (501). By cutting open the bottom of the masterbatch raw material packaging bag (401), the plastic semi-finished masterbatch raw material falls into the silo (501) and is discharged into the processing equipment through the discharge pipe (502).
