[0001] This utility model belongs to the technical field of material feeding devices for blow molding machines, and in particular relates to a material feeding device for blow molding machines. Background Technology

[0002] The feeding device of a blow molding machine is a key auxiliary device that connects the blow molding process with subsequent processing, inspection, or warehousing. Its core function is to smoothly and efficiently transfer the hollow plastic products ejected from the molding station after the blow molding mold is opened. According to production needs, it performs pre-processing or auxiliary operations such as cooling, deflashing, sorting, and counting, and finally delivers qualified finished products to designated areas to achieve continuous and automated blow molding production, reduce manual intervention, and ensure product quality and production efficiency.

[0003] However, when the existing equipment is used, its fixed height makes it difficult to match the discharge port of the blow molding machine with the device. This not only increases the difficulty of on-site installation and commissioning, but also causes problems such as poor material conveying and leakage due to docking deviation, which affects production efficiency and product quality. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding device for a blow molding machine. By setting up a lifting part, it solves the problem that when docking with different blow molding machines, the fixed height of the device makes it difficult to match the discharge port of the blow molding machine. This not only increases the difficulty of on-site installation and debugging, but also causes problems such as poor material conveying and leakage due to docking deviation, which affects production efficiency and product quality.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a feeding device for a blow molding machine, comprising a base plate, and further comprising: a lifting part disposed on the top of the base plate; a positioning part disposed on the top of the lifting part; the lifting part comprising a lifting assembly mounted on the base plate; and a limiting assembly mounted on the lifting assembly; the lifting assembly comprising a U-shaped frame fixedly connected to the top of the base plate, a motor fixedly connected to the left side of the U-shaped frame, the output shaft of the motor being fixedly connected to a rotating shaft via a coupling, and the outer side of the rotating shaft... A connecting rod 1 is fixedly connected to the wall. A connecting rod 2 is hinged to the end of the connecting rod 1 away from the pivot. A U-shaped frame 2 is hinged to the end of the connecting rod 2 away from the connecting rod 1. A top plate is fixedly connected to the top of the U-shaped frame 2. A balancing component is provided on the bottom plate. The pivot passes through the U-shaped frame 1 and is rotatably connected to the U-shaped frame 1. The balancing component includes several sleeves fixedly connected to the top of the bottom plate. Each of the several sleeves has a sliding rod 1 slidably connected inside it. The top ends of the several sliding rods 1 are fixedly connected to the top plate. There are four sleeves and four sliding rods 1.

[0006] Furthermore, the positioning part includes a positioning component mounted on the top of the top plate; and a driving component mounted on the positioning component.

[0007] Furthermore, the limiting component includes a limiting plate fixedly connected to the right side of the U-shaped frame, a limiting rod fixedly connected to the outer wall of the right end of the rotating shaft, an insert rod slidably connected to the limiting rod, the left end of the insert rod extending into the limiting plate, and the right end of the rotating shaft extending out of the limiting plate and rotatably connected to the limiting plate. The limiting plate on the right side of the U-shaped frame provides support for the rotation of the rotating shaft, and cooperates with the limiting rod on the outer wall of the right end of the rotating shaft to construct the limiting foundation of the rotating shaft.

[0008] Furthermore, the positioning assembly includes a conveyor frame fixedly connected to the top of the top plate. Two slide rods are slidably connected to both sides of the conveyor frame. Two guide rollers are fixedly connected to the ends of several slide rods that are close to each other. Connectors are provided on the two guide rollers. There are four slide rods, which slide in pairs on the left and right sides of the conveyor frame. The connectors include rectangular blocks that are fixedly connected to the top of the two guide rollers. Connecting rods are hinged to the top of the two rectangular blocks. The ends of the two connecting rods away from the guide rollers are hinged to the slide plate. The conveyor frame at the top of the top plate provides a sliding base for the slide rods.

[0009] Furthermore, the drive assembly includes a mounting plate fixedly connected to the top of the conveyor frame. Two slide rod assemblies are slidably connected to the mounting plate. A slide plate is fixedly connected to the front end of each slide rod assembly. A hydraulic push rod is fixedly connected to the top of the mounting plate. The output end of the hydraulic push rod is fixedly connected to the slide plate. The mounting plate on the top of the conveyor frame provides a stable mounting foundation for the slide rod assemblies, slide plate, and hydraulic push rod, ensuring stable operation of the power components.

[0010] This utility model has the following beneficial effects: 1. By setting up a lifting unit, when matching the device with the discharge port of a blow molding machine of different sizes, first pull out the insert rod on the limit rod to release the limit on the rotating shaft; start the motor, and the motor drives the connecting rod one to rotate through the rotating shaft. Because the other end of the connecting rod two, which is hinged to the connecting rod one, is hinged to the U-shaped frame two at the bottom of the top plate, the top plate drives the device on it to adjust to the appropriate position through the transmission between the two. During the adjustment, the sliding rod one at the bottom of the top plate slides synchronously in the bottom plate sleeve to ensure stability. After the adjustment is completed, reinsert the insert rod into the limit rod and the limit plate of the U-shaped frame one to limit the rotating shaft and prevent accidental rotation. This setting can achieve precise docking of the device with discharge ports of different sizes, improving the adaptability of the equipment and the convenience of operation.

[0011] 2. By setting up a positioning unit, after the device is adjusted, the finished product of the blow molding machine falls onto the conveyor frame and is transported to the subsequent process. If it is necessary to adjust according to the size of the finished product before conveying, the hydraulic push rod is activated, which drives the slide plate to move with the help of two sliding rod groups. Since the other end of the two connecting rods three of the slide plate is hinged to the guide roller, when the slide plate moves, it is driven by the connecting rod three, so that the two guide rollers move closer or further apart with the cooperation of the sliding rod two, and the finished product on the conveyor frame is centered and positioned. This setting can prevent the finished product from deviating, falling or colliding with the equipment during the conveying process, ensuring the stability and safety of the conveying and reducing product loss.

[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 As shown, this utility model is a feeding device for a blow molding machine, including a base plate 1, and further including: a lifting part 2, which is disposed on the top of the base plate 1; and a positioning part 3, which is disposed on the top of the lifting part 2.

[0018] The lifting unit 2 includes a lifting assembly 21, which is mounted on the base plate 1; and a limiting assembly 22, which is mounted on the lifting assembly 21. The lifting assembly 21 includes a U-shaped frame 211 fixedly connected to the top of the base plate 1. A motor 212 is fixedly connected to the left side of the U-shaped frame 211. The output shaft of the motor 212 is fixedly connected to a rotating shaft 213 via a coupling. A connecting rod 214 is fixedly connected to the outer wall of the rotating shaft 213. A connecting rod 215 is hinged to the end of the connecting rod 214 away from the rotating shaft 213. A U-shaped frame 216 is hinged to the end of the connecting rod 215 away from the connecting rod 214. A top plate 217 is fixedly connected to the top of the U-shaped frame 216. A balancing component is provided on the base plate 1. The rotating shaft 213 passes through... A U-shaped frame 211 is inserted and rotatably connected to it. The limiting assembly 22 includes a limiting plate 221 fixedly connected to the right side of the U-shaped frame 211. A limiting rod 222 is fixedly connected to the outer wall of the right end of the rotating shaft 213. An insert rod 223 is slidably connected to the limiting rod 222. The left end of the insert rod 223 extends into the limiting plate 221, and the right end of the rotating shaft 213 extends outside the limiting plate 221 and rotatably connects to it. The balancing component includes several sleeves 218 fixedly connected to the top of the base plate 1. Each sleeve 218 has a sliding rod 219 slidably connected to it. The top ends of each sliding rod 219 are fixedly connected to the top plate 217. Four sleeves 218 and four sliding rods 219 are provided. A lifting part 2 is provided. When using this device to match the discharge port of blow molding machines of different sizes, first pull out the insert 223 on the limiting rod 222 so that the insert 223 can release the limiting rod 222 on the rotating shaft 213, allowing the rotating shaft 213 to drive the limiting rod 222 to rotate freely. Then, the motor 212 can be started. The motor 212 will drive the connecting rod 1 214 to rotate through the rotating shaft 213. Since the connecting rod 1 214 is hinged with the connecting rod 215, and the other end of the connecting rod 215 is hinged to the U-shaped frame 216 at the bottom of the top plate 217, when the motor 212 drives the connecting rod 1 214 to rotate through the rotating shaft 213, the transmission between the connecting rod 215 and the U-shaped frame 216 will allow the U-shaped frame to rotate freely. The top plate 217 at the top of the second 216 can drive the device on it to adjust to a position that matches the discharge port of different sizes of blow molding machines. During the adjustment of the top plate 217, the multiple sliding rods 219 at its bottom will also slide synchronously in the multiple sleeves 218 at the top of the base plate 1, thus ensuring the stability of the top plate 217 during the adjustment process. After the top plate 217 and the device on it are adjusted, the insertion rod 223 can be reinserted into the limiting rod 222 on the rotating shaft 213 and the limiting plate 221 on the U-shaped frame 211 to limit the rotating shaft 213 and prevent it from accidentally rotating the device on it. Through this setting, the device can be quickly and accurately connected to the discharge port of different sizes of blow molding machines, greatly improving the adaptability and ease of operation of the equipment.

[0019] The positioning unit 3 includes a positioning assembly 31, which is mounted on the top of the top plate 217; and a driving assembly 32, which is mounted on the positioning assembly 31. The positioning assembly 31 includes a conveyor frame 311 fixedly connected to the top of the top plate 217. Two slide rods 312 are slidably connected to both sides of the conveyor frame 311. Two guide rollers 313 are fixedly connected to the ends of several slide rods 312 that are close to each other. Connectors are provided on the two guide rollers 313. There are four slide rods 312, which slide in pairs on the left and right sides of the conveyor frame 311. The drive assembly 32 includes a mounting plate 321 fixedly connected to the top of the conveyor frame 311. Two slide rod assemblies 322 are slidably connected to the mounting plate 321. A slide plate 323 is fixedly connected to the front end of each slide rod assembly 322. A hydraulic push rod 324 is fixedly connected to the top of the mounting plate 321. The output end of the hydraulic push rod 324 is fixedly connected to the slide plate 323. The connecting parts include rectangular blocks 314 fixedly connected to the tops of the two guide rollers 313. Connecting rods 315 are hinged to the tops of the two rectangular blocks 314. The two connecting rods 315 are located away from the guide rollers 313. One end is hinged to the slide plate 323. With the positioning part 3, after all adjustments are made, the finished product produced on the blow molding machine will fall onto the conveyor frame 311. At this time, the finished product can be conveyed to the subsequent process via the conveyor frame 311. Before conveying, if the device needs to be adjusted according to the size of the finished product, the hydraulic push rod 324 can be activated. The hydraulic push rod 324 will move the slide plate 323 on the slide rod assembly 322 via two slide rod assemblies 322. Since two connecting rods 315 are hinged to the slide plate 323, and the other... One end of each guide roller 313 is hinged to the other two guide rollers 313. Therefore, during the movement of the slide plate 323 driven by the hydraulic push rod 324, the two guide rollers 313 hinged to the two connecting rods 315 can move closer or further apart with the cooperation of the upper slide rods 312. This can center the product being conveyed on the conveyor frame 311 and prevent it from shifting, falling or colliding with the edge of the equipment during the conveying process. This setting can ensure the stability and safety of the finished product conveying process and reduce product loss.

[0020] It should be noted that the control of the motor 212 and the hydraulic push rod 324 in this application can be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be implemented using existing technologies, such as PLC.

[0021] A specific application of this embodiment is as follows: When using this device to match the discharge port of blow molding machines of different sizes, the insert rod 223 on the limiting rod 222 can be pulled outwards first, so that the insert rod 223 can release the limiting rod 222 on the rotating shaft 213, allowing the rotating shaft 213 to drive the limiting rod 222 to rotate freely. Then, the motor 212 can be started. The motor 212 will drive the connecting rod 1 214 to rotate through the rotating shaft 213. Since the connecting rod 214 is hinged to the connecting rod 215, and the other end of the connecting rod 215 is hinged to the U-shaped frame 216 at the bottom of the top plate 217, the motor 212 can drive the connecting rod 214 to rotate freely. When shaft 213 drives connecting rod 214 to rotate, the transmission between connecting rod 215 and U-shaped frame 216 allows the top plate 217 of U-shaped frame 216 to adjust its device to a position suitable for the discharge port of blow molding machines of different sizes. During the adjustment of top plate 217, multiple sliding rods 219 at its bottom will also slide synchronously within multiple sleeves 218 on the top of base plate 1, thus ensuring the stability of top plate 217 during adjustment. After the top plate 217 and its device are properly adjusted, the insert rod 223 can be reinserted into the limiting rod 222 on shaft 213 and the limiting disc 2 on U-shaped frame 211. Within 21, the rotating shaft 213 is limited to prevent it from accidentally rotating the device on it. This setting allows for quick and precise docking of the device with the discharge port of blow molding machines of different sizes, greatly improving equipment adaptability and ease of operation. After all adjustments are made, the finished product produced on the blow molding machine will fall onto the conveyor frame 311. At this time, the finished product can be conveyed to the subsequent process via the conveyor frame 311. If the device needs to be adjusted according to the size of the finished product before conveying, the hydraulic push rod 324 can be activated. The hydraulic push rod 324 will move the slide plate 323 on the slide rod assembly 322 with the help of two slide rod assemblies 322. 3 has two connecting rods 315 hinged to it, and the other end of each connecting rod 315 is hinged to two guide rollers 313. Therefore, during the movement of the slide plate 323 driven by the hydraulic push rod 324, the two guide rollers 313 hinged to the two connecting rods 315 can move closer or further away from each other with the cooperation of the upper slide rod 312. This can center the product being conveyed on the conveyor frame 311 and prevent it from shifting, falling or colliding with the edge of the equipment during the conveying process. This setting can ensure the stability and safety of the finished product conveying process and reduce product loss.
