[0001] This utility model relates to the technical field of sprue cutting machinery and equipment, specifically to a sprue cutting robot for injection molded bottle preforms. Background Technology

[0002] In the production of plastic preforms, the removal of the sprue at the end of the preform has always been a critical step. Currently, many manufacturers still use manual methods to cut the sprue after the preforms are injection molded on a sprue machine. This traditional manual method not only increases labor costs but also leads to low production efficiency due to the instability and variability of manual operation. Furthermore, the cutting effect is difficult to guarantee, which can easily result in defective products. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of existing technologies and provide a cutting robot for injection-molded bottle preforms. The mounting base of the mounting frame provides a stable foundation for the robot, and the raised seat effectively reduces the impact or vibration generated during operation on the foundation structure, ensuring the stability of the cutting robot's operation. The angle and position of the cutting robot can be adjusted through a rotation adjustment mechanism, ensuring that the robot can be flexibly adjusted according to different production needs and adapt to the cutting requirements of bottle preforms at different positions. The precise coordination of the lifting linear module and the horizontal linear module achieves accurate displacement of the sprue cutting mechanism in the vertical and horizontal directions, thereby ensuring the accuracy and consistency of the cutting action. At least two sets of cutting blade components in the sprue cutting mechanism allow multiple materials to be cut off from the sprue simultaneously, greatly improving production efficiency. Through the coordinated work of components such as the cutting cylinder, floating joint, and cutting blade in the cutting blade assembly, the cutting blade, guided by the limiting plate and positioning plate, ensures that it cuts into the sprue area of ​​the material with stable force and speed, avoiding the instability and variability of manual operation, and ensuring the stability of the cutting effect and the yield rate of the product.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A cutting robot for injection-molded bottle preforms includes a mounting frame for connection to processing equipment. The mounting frame is connected to a lifting linear module via a rotary adjustment mechanism for adjusting the horizontal turning angle of the lifting linear module. A horizontal linear module is provided on one side of the lifting linear module for adjusting its vertical displacement. The horizontal linear module is connected to a sprue-cutting mechanism for processing and cutting the material.

[0006] The sprue cutting mechanism consists of a connecting plate on one side of the horizontal linear module, an adjusting plate on one end of the connecting plate, at least two sets of cutting assemblies on one side of the adjusting plate, a sprue funnel below the cutting assemblies, and a sprue collection funnel below the sprue funnel. The sprue collection funnel is fixedly connected to the adjusting plate via a reinforcing plate. The connecting plate is used to slide with the adjusting plate and the horizontal linear module. The adjusting plate is used to install the cutting assemblies. The cutting assemblies are used to process and trim the material. The sprue funnel is used to collect and transfer the sprue material in conjunction with the sprue collection funnel.

[0007] The cutter assembly consists of a cutter seat located on one side of the adjusting plate, a cutter cylinder connected to the cutter seat via a cylinder pressure plate, a floating connector located at the output end of the cutter cylinder, a cutter connected to one end of the floating connector via a floating seat, a limiting plate located below the cutter, and a positioning plate located on the limiting plate.

The limiting plate is used to guide the direction of travel of the cutter. The positioning plate is used to cooperate with the cutter seat to position the material.

[0008] The cutter holder has a slot, and a retaining groove is provided at one end of the slot. The slot is used to limit the position of the cutter cylinder. A cutting groove is provided at the other end of the slot. The cutting groove is used to install the cutter in the cutter cylinder. A discharge port is provided at one end of the cutting groove. The discharge port is used to allow the cut sprue material to fall into the sprue funnel.

[0009] The sprue funnel is provided with an inclined chute, and a discharge port is provided at one end of the chute. The chute is used to cooperate with the discharge port to slide the sprue material into the discharge port.

[0010] The sprue collecting funnel is provided with a chute inclined to one end, and a collecting conduit is provided at the lower end of the chute. The chute is used to collect sprue material in conjunction with the discharge port and guide the sprue material into the collecting conduit. The collecting conduit is used to discharge the sprue material. An installation plate is provided on the outside of the sprue collecting funnel. The installation plate is used to fix the reinforcing plate and the adjusting plate together.

[0011] The mounting frame consists of a mounting base plate and a raised platform mounted on the mounting base plate. The mounting base plate provides a stable foundation for the tail-cutting robot. The raised platform is used to increase the height of the tail-cutting robot. The raised platform consists of a base plate mounted on the mounting base plate, a heightening plate mounted on the base plate, and a top plate mounted on the heightening plate. The base plate reduces the impact or vibration generated by the tail-cutting robot during operation on the mounting base plate and foundation structure.

Through the close cooperation of the lifting linear module and the horizontal linear module, the sprue cutting mechanism can be quickly and accurately moved to the bottom of the material and lifted to the sprue cutting position, realizing automated operation without manual intervention, which greatly saves labor costs and operation time. The sprue cutting mechanism is equipped with at least two sets of cutting blade components, which can simultaneously cut sprue material from multiple materials, greatly improving the production capacity per unit time and effectively solving the problem of low efficiency in traditional manual sprue cutting methods.

[0015] 2. The cutter assembly, including the cutter cylinder, floating joint, and cutter, works in concert to ensure that the cutter, guided by the limiting plate and positioning plate, cuts into the material's sprue area with stable force and speed. This avoids the instability and variability of manual operation, ensuring the stability and consistency of the shearing effect. The cut sprue material is collected and transferred in a timely manner through the sprue funnel and sprue collection funnel, avoiding interference from waste material in the processing and further ensuring product quality. This tail-cutting robot automatically completes the bottle preform tail-cutting work, effectively solving the problems of poor shearing effect and high defect rate caused by manual sprue cutting, and realizing a highly efficient, stable, and automated sprue cutting process.

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] As shown in Figures 1-10, this utility model relates to a cutting robot for injection-molded bottle preforms, including a mounting frame 1 for mounting the cutting device. The mounting frame 1 has a rotation adjustment mechanism 2 for adjusting the angle of the lifting linear module 3 of the cutting robot to meet the material cutting process. A lifting linear module 3 is mounted on the rotation adjustment mechanism 2 for adjusting the vertical displacement of the horizontal linear module 4 of the cutting robot. A sprue cutting mechanism 5 is slidably connected to one side of the lifting linear module 3 via the horizontal linear module 4. The horizontal linear module 4 is used to fine-tune the horizontal displacement of the sprue cutting mechanism 5, which is used to cut the material. After the mounting frame 1 is fixedly connected to the device, the working position of the cutting robot is adjusted by the rotation adjustment mechanism 2, and the lifting linear module... The precise coordination between the horizontal linear module 3 and the horizontal linear module 4 accurately adjusts the processing position of the sprue cutting mechanism 5 to efficiently remove sprue material from the material in conjunction with the automated production line. When the horizontal linear module 4 drives the sprue cutting mechanism 5 to move directly below the material, the lifting linear module 3 then drives the sprue cutting mechanism 5 to rise to the material shearing position, allowing the sprue cutting mechanism 5 to precisely remove the sprue material. After completion, the lifting linear module 3 drives the sprue cutting mechanism 5 to descend and disengage from the material shearing position. The automated production line then moves the material that has completed the tail-cutting process forward, and the next batch of materials to be processed enters the workstation. The lifting linear module 3 then drives the sprue cutting mechanism 5 to rise to the shearing position again, and the process is repeated in a cycle. No manual operation is required. The sprue material of multiple materials is removed simultaneously by two or more sets of cutting blade components 52 in the sprue cutting mechanism 5, improving the production efficiency of the product, with good shearing effect and high yield.

[0030] As shown in Figures 1-2, the mounting frame 1 consists of a mounting base plate 10 and a raised seat 11 mounted on the mounting base plate 10. The mounting base plate 10 provides a stable fixed foundation for the tail-cutting robot. The raised seat 11 is used to increase the height of the tail-cutting robot. The raised seat 11 consists of a base plate 110 mounted on the mounting base plate 10, a heightening plate 111 mounted on the base plate 110, and a top plate 112 mounted on the heightening plate 111. The base plate 110 reduces the impact and vibration generated by the tail-cutting robot during operation on the mounting base plate 10. The heightening plate 111 increases the height of the tail-cutting robot to meet the tail-cutting operation requirements of different heights. The top plate 112 ensures the flatness and verticality accuracy requirements of the connection with the tail-cutting robot.

[0031] As shown in Figures 1 and 3, the rotation adjustment mechanism 2 consists of a rotation adjustment seat 20 on the top plate 112 and a clamping seat 21 on the rotation adjustment seat 20. The clamping seat 21 is used to adjust the rotation angle in conjunction with the rotation adjustment seat 20. The rotation adjustment seat 20 consists of a rotating base 200 and a rotating shaft 201. The rotating base 200 of the rotation adjustment seat 20 is fixedly installed on the top plate 112, and the clamping seat 21 is sleeved on the rotating shaft 201. The angle of the clamping seat 21 is adjusted, and the clamping seat 21 is locked by the clamping bolt 22, so that the rotating shaft 201 and the clamping seat 21 are tightly connected.

[0032] As shown in Figures 1 and 4-9, the sprue cutting mechanism 5 consists of a connecting plate 50 located on one side of the horizontal linear module 4, an adjusting plate 51 located at one end of the connecting plate 50, at least two sets of cutting blade assemblies 52 located on one side of the adjusting plate 51, a sprue funnel 53 located below the cutting blade assembly 52, and a sprue collection funnel 54 located below the sprue funnel 53. The sprue collection funnel 54 is fixedly connected to the adjusting plate 51 via a reinforcing plate 55. The connecting plate 50 is used to slide with the adjusting plate 51 and the horizontal linear module 4. The adjusting plate 51 is used to mount the cutting blade assembly 52, which is used to process and trim the material. The sprue funnel 53 is used to collect and transfer sprues in conjunction with the sprue collection funnel 54. The connecting plate 50 is vertically fixedly connected to the adjusting plate 51. The adjusting plate 51 has adjusting holes 510 corresponding to the installation positions of each set of cutter assemblies 52. The adjusting plate 51 also has adjusting blocks 511 corresponding to the installation positions of each set of cutter assemblies 52. The adjusting bolts 512 are threadedly connected to the cutter assemblies 52. The installation height of the cutter assemblies 52 on the adjusting plate 51 is adjusted by adjusting bolts 512. The adjusting holes 510 and adjusting blocks 511 on the adjusting plate 51, together with the adjusting bolts 512, can finely adjust the installation height of the cutter assemblies 52 according to the material specifications to adapt to the tail-cutting operation with different height requirements, ensuring that the cutting action is accurately matched with the material position, thereby realizing an efficient and stable material nozzle tail-cutting process in the automated production line.

[0033] As shown in Figure 5-9, the cutter assembly 52 further comprises a cutter seat 520 located on one side of the adjusting plate 51, a cutter cylinder 522 located on the cutter seat 520 and connected by a cylinder pressure plate 521, a floating connector 523 located at the output end of the cutter cylinder 522, a cutter 525 located at one end of the floating connector 523 and connected by a floating seat 524, a limiting plate 526 located below the cutter 525, a positioning plate 527 located on the limiting plate 526, and a cover plate 528 located on the cutter cylinder 522. The cutter seat 520 is used to cooperate with the adjusting plate 51 to install the cutter cylinder 522 and the cutter 525. The cutter cylinder 522 is used to cooperate with the floating connector 523 to drive the cutter 525 to move. The cutter 525 is used to trim the material. The limiting plate 526 is used to guide the travel direction of the cutter 525. The positioning plate 527 is used to guide the material to move. The cover plate 528 is used to position the material in conjunction with the cutter holder 520. It also forms a protective barrier for the cutter cylinder 522. The limiting plate 526 has a guide groove 5260 that matches the cutter 525. The cutter assembly 52 is the key actuator of the tail-cutting robot. It mainly performs precise tail-cutting operations on the material sprue. The cutter cylinder 522 is mounted on the cutter holder 520 through the cylinder pressure plate 521. When the cutter cylinder 522 is started, its output end is connected to the floating seat 524 through the floating connector 523, driving the cutter 525 to cut into the material sprue area with controllable force and speed along the guide groove 5260 in the limiting plate 526, completing the cutting action. Through the cooperation of the limiting plate 526 and the positioning plate 527, the cutter maintains a stable and precise movement trajectory during the tail-cutting process, avoiding incomplete cutting or material damage caused by cutter deviation.

[0034] As shown in Figure 7-9, further, the cutter holder 520 is provided with a slot 5200, and a retaining groove 5201 is provided at one end of the slot 5200. The slot 5200 is used to limit the cutting cylinder 522 in conjunction with the retaining groove 5201. A cutting groove 5202 is provided at the other end of the slot 5200. The cutting groove 5202 is used to install the cutter 525 in conjunction with the cutting cylinder 522. A discharge port 5203 is provided at one end of the cutting groove 5202. The discharge port 5203 is used to allow the sprue material cut by the cutter 525 to fall into the sprue funnel 53. The slot 5200 is used to install the cutting cylinder 522. The tail end of the cutting cylinder 522 is installed in the retaining groove 5201. A cylinder pressure plate is used between the slot 5200 and the retaining groove 5201. 521. Fix the cutter cylinder 522 onto the cutter holder 520. Install the limiting plate 526 inside the cutter groove 5202. The guide groove 5260 of the limiting plate 526 faces outward. Then, install the cutter 525 into the cutter groove 5202 along the guide groove 5260. One end of the cutter 525 is connected to the output end of the cutter cylinder 522 through the cooperation of the floating seat 524 and the floating connector 523. The cutting edge of the cutter 525 faces the side of the discharge port 5203. The groove 5200 and the slot 5201 on the cutter holder 520 provide a stable installation base for the cutter cylinder 522 to prevent the cutter cylinder 522 from shifting due to vibration during shearing. The cutter groove 5202 and the discharge port 5203 allow the sheared sprue material to fall smoothly into the sprue funnel 53 for subsequent collection and processing.

[0035] As shown in Figures 5-7 and 10, the sprue funnel 53 is provided with an inclined chute 530, and a discharge port 531 is provided at one end of the chute 530. The chute 530 is used to cooperate with the discharge port 5203 to slide the sprue material into the discharge port 531. One end of the chute 530 cooperates with the discharge port 5203. The sprue funnel 53 is installed in the same direction as the cutter holder 520. Each cutter holder 520 is provided with a corresponding sprue funnel 53. The sprue funnel 53 is an important supporting component of the tail-cutting robot. Its main function is to collect and guide the cut sprue material in a timely manner after the cutter 525 completes the tail-cutting action. The material is transferred to ensure the orderly handling of waste during material processing. After the cutter assembly 52 cuts the sprue material, the cut sprue material falls into the inclined chute 530 through the discharge port 5203. The discharge port 531 at one end of the chute 530 is connected to the sprue material collection funnel 54. Due to the inclination angle of the chute 530 and the gravity of the sprue material itself, the sprue material slides smoothly into the discharge port 531 along the chute 530 and is then guided into the sprue material collection funnel 54, realizing the centralized collection of sprue material, avoiding the accumulation of waste in the processing area, and maintaining the smooth operation of subsequent automated production processes.

[0036] As shown in Figures 5-7 and 10, the sprue collecting funnel 54 has a chute 540 inclined at one end. A collecting conduit 541 is located at the lower end of the chute 540. The chute 540 cooperates with the discharge port 531 to collect sprue material and guide it into the collecting conduit 541. The collecting conduit 541 is used to discharge the sprue material. A mounting plate 542 is provided on the outer side of the sprue collecting funnel 54. The mounting plate 542 is used to cooperate with the reinforcing plate 55 and the adjusting plate 51 for fixed connection. The sprue collecting funnel 54 is a supporting component of the tail-cutting robot. The main function is to collect and centrally discharge the sprue material cut by the cutter assembly 52, ensuring efficient and orderly waste treatment. The sprue material collection funnel is connected to the adjustment plate 51 through the mounting plate 542 to ensure structural stability. The sprue material cut by the cutter 525 is guided by the chute 530 of the sprue funnel 53 and falls from the discharge port 531 into the inclined chute 540 of the sprue material collection funnel 54. It slides down the chute 540 by gravity and is guided to the designated collection container through the collection conduit 541 connected to the lower end of the chute 540, keeping the production environment clean.

[0037] Working principle: First, fix the mounting base plate 10 of the mounting bracket 1 to the equipment. Then, install the base plate 110, the raising plate 111, and the top plate 112 of the raised seat 11 onto the mounting base plate 10 in sequence. The rotating base 200 of the rotating adjustment mechanism 2 is installed on the top plate 112. The clamping seat 21 is sleeved on the rotating shaft 201 and locked by the clamping bolts 22 to adjust the rotation angle. The lifting linear module 3 is installed on the rotating adjustment mechanism 2. One side of the horizontal linear module 4 is connected to the sliding side of the lifting linear module 3. (Water cutter...) Mechanism 5 is installed on the other side of the horizontal straight module 4. The sprue cutting mechanism 5 consists of a connecting plate 50, an adjusting plate 51, a cutter assembly 52, a sprue funnel 53, and a sprue collecting funnel 54. The connecting plate 50 is slidably connected to the sliding side of the horizontal straight module 4. The adjusting plate 51 is vertically fixedly connected to the connecting plate 50. The cutter assembly 52 is installed on the adjusting plate 51. The sprue funnel 53 is located below the cutter assembly 52 and is connected to the sprue collecting funnel 54.

The cutter assembly 52 consists of a cutter holder 520, a cutter cylinder 522, a floating connector 523, a cutter 525, a limiting plate 526, and a positioning plate 527. The cutter cylinder 522 is fixed to the cutter holder 520 via a cylinder pressure plate 521. The cutter 525 is connected to the floating connector 523. The limiting plate 526 and the positioning plate 527 work together to guide and position the cutter 525. When the tail-cutting operation begins, the mounting frame 1 is fixedly connected to the equipment. The rotation adjustment mechanism 2 adjusts the working position of the tail-cutting robot to coordinate with the automatic production line. The lifting linear module 3 and the horizontal linear module 4 work closely together. The horizontal linear module 4 moves the cutting nozzle mechanism 5 directly below the material. The lifting linear module 3 then lifts it to the material cutting nozzle position. The cutter cylinder 522 is activated, driving the cutter 525 to cut into the material along the guide groove 5260 in the limiting plate 526. The shearing action is completed at the sprue section. The cut sprue material falls through the discharge port 5203 below the cutter 525 into the chute 530 of the sprue funnel 53, then slides into the discharge port 531, enters the chute 540 of the sprue collection funnel 54, and is finally discharged through the collection conduit 541. This tail-cutting robot automatically completes the material tail-cutting work, greatly improving production efficiency. It can simultaneously cut sprue material from multiple materials with good shearing effect and high yield, reducing labor costs and labor intensity, and avoiding the safety hazards and quality problems that may occur with manual tail-cutting. At the same time, the coordinated use of the rotary adjustment mechanism 2, the lifting linear module 3, and the horizontal linear module 4 allows this tail-cutting robot to be flexibly adjusted according to different production needs, making it highly adaptable and widely applicable in the injection molding field, especially in the production and processing of plastic products such as preforms.
