Description

Technical Field

[0001] This utility model relates to the technical field of waste material collection equipment, specifically to waste material collection equipment for sprue outlets. Background Technology

[0002] In the injection molding process of plastic parts, the handling of sprue residue is an indispensable and important step. With the continuous improvement of the level of automation in the manufacturing industry, more and more injection molding equipment is equipped with robotic arms and pick-up devices to work together. During the process of removing the injection molded part from the injection molding machine, the sprue can be removed by the robotic arm while it is suspended in the air at a high position. This high-level sprue removal method greatly improves production efficiency.

[0003] However, technological innovation also brings new challenges. When removing sprue nozzles at a high elevation, residual material often splashes out. Currently, the common practice is to install baffles around the robotic arm to limit this splashing. While this helps prevent the material from scattering to some extent, it doesn't effectively solve the problem of messy, scattered sprue nozzle material falling from a height. This messy, scattered material not only increases the difficulty of on-site cleanup but also reduces the efficiency of material collection, failing to meet the demands of efficient and orderly automated production. Therefore, there is an urgent need to design equipment capable of directional collection of sprue nozzle material. Utility Model Content

[0004] The purpose of this invention is to provide a sprue residue collection device to solve the problem mentioned in the background art, which is to limit the splashing of residue by setting up a curtain around the robot arm. Although this can prevent the residue from flying around to a certain extent, it still cannot effectively solve the problem of the messy scattering of sprue residue falling from a high position.

[0005] To achieve the above objectives, this utility model provides a sprue residue collection device, including a collection chamber. The collection chamber is a square chamber with an open top. Baffles are installed on the top of the four side walls of the collection chamber. The outer side of the baffles is protected by a protective frame. A guide plate is fixedly installed inside the collection chamber. A discharge port is opened in the middle of the guide plate. The guide plate is inclined along the inner wall of the collection chamber to the discharge port. A negative pressure pump is connected to the bottom of the collection chamber through a negative pressure pipe.

[0006] This feature includes an opening at the top of the collection bin to facilitate the entry of residual material from the sprue, and a square bin providing a regular collection space; baffles on the top of the four side walls prevent residual material from splashing, and a protective frame further protects the baffles; an inclined guide plate allows residual material to slide down the slope to the discharge port using gravity; and a negative pressure pump connected to the negative pressure pipe generates negative pressure suction to draw the residual material falling to the discharge port into the designated channel.

[0007] Preferably, a cleaning door is installed on one side of the bottom of the collection chamber, and a base is installed on the bottom of the collection chamber.

[0008] The cleaning door provides staff with access to the collection chamber, facilitating the cleaning of residual materials and debris. The base is installed at the bottom of the collection chamber, increasing the contact area between the equipment and the ground and enhancing the stability of the equipment.

[0009] Preferably, the protective frame includes a baffle, which is fixedly sleeved on the outside of the curtain. Several buffer pads are installed on the inner side wall of the baffle, and the buffer pads abut against the outer side wall of the curtain.

[0010] The baffles of this protective frame support and protect the curtain, while the buffer pads on the inner wall absorb the impact force and reduce the impact intensity when residual material splashes and hits the curtain.

[0011] Preferably, the negative pressure port of the negative pressure pipe is located below the discharge port, and a protective net is installed at the top of the negative pressure port end of the negative pressure pipe.

[0012] The negative pressure port of this device is located below the discharge port, which can accurately generate suction force on the residual material falling to this point; the protective net is installed on the top of the negative pressure port end to prevent large residual material or debris from entering the negative pressure pipe and avoid pipe blockage.

[0013] Preferably, the protective net adopts a conical structure, and the material falling from the discharge port slides to the side through the inclined surface of the conical structure.

[0014] This protective net features a conical structure, the slope of which can change the direction of material falling from the discharge port, causing the material to slide along the slope and avoid direct accumulation at the negative pressure port.

[0015] Preferably, the aperture size of the protective net is smaller than the width of the sprue residue.

[0016] This feature sets up a protective mesh with a mesh size smaller than the width of the sprue residue, thus restricting the residue from entering the negative pressure pipe. Only small debris that meets the size requirements can pass through, while the main sprue residue is blocked.

[0017] Preferably, the inner surface of the guide plate is fitted with several silicone pads for cushioning.

[0018] The silicone pads on the surface of the guide plate are elastic. When the excess material falls and hits the guide plate, the pads can cushion the impact and reduce the collision force on the excess material.

[0019] Preferably, the inner wall surface of the collection chamber is coated with a wear-resistant coating.

[0020] This wear-resistant coating has high hardness and wear resistance. After being applied to the inner wall surface of the collection bin, it can effectively resist friction and impact during the falling of residual material.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This sprue residue collection device effectively solves the problems existing in traditional sprue residue collection through a series of innovative structural designs, achieving significant technical results.

[0023] In terms of splash prevention and directional collection, the baffles on the top of the four side walls of the collection chamber, together with the outer protective frame, form an effective splash barrier, reducing the scattering of residual material. The inclined guide plate inside the collection chamber guides the residual material to slide down the slope to the discharge port. Combined with the design of the negative pressure pump connected to the bottom of the collection chamber through the negative pressure pipe, the residual material is accurately and quickly put into the designated channel by using negative pressure suction, realizing the directional collection of residual material from the sprue, greatly improving the collection efficiency and avoiding the cleaning problems caused by the scattering of residual material.

[0024] In terms of equipment protection and stable operation, the buffer pads on the inner wall of the protective frame baffle can reduce the impact of splashed residual material on the baffle curtain, extending the service life of the baffle curtain; the silicone pads on the inner surface of the guide plate can buffer the impact force of falling residual material, reducing damage to residual material and noise generation; the wear-resistant coating on the inner wall of the collection bin enhances the wear resistance of the bin body and extends the overall service life of the equipment. At the same time, the conical structure of the protective net at the negative pressure port of the negative pressure pipe, with an aperture smaller than the width of the residual material, can not only prevent residual material from clogging the negative pressure port, but also guide the residual material to slide sideways through the inclined surface, ensuring the stable operation of the negative pressure system.

[0030] 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.

[0031] This utility model provides a device for collecting residual material from sprue outlets, such as... Figure 1 , Figure 2 , Figure 3 As shown, the collection chamber includes a collection bin 1, which is a square chamber with an open top. The top of the four side walls of the collection bin 1 is equipped with a curtain 11. The outer side of the curtain 11 is protected by a protective frame 2. A guide plate 3 is fixedly installed inside the collection bin 1. A discharge port 31 is opened in the middle of the guide plate 3. The guide plate 3 is inclined along the inner wall of the collection bin 1 to the discharge port 31. The bottom of the collection bin 1 is connected to a negative pressure pump 41 through a negative pressure pipe 4.

[0032] In use, the top opening of the collection chamber 1 facilitates the entry of residual material from the sprue, and the square chamber provides a regular collection space. The baffles 11 installed on the top of the four side walls prevent splashing of residual material, and the protective frames 2 on the outside of the baffles 11 further protect them. The guide plate 3 installed in the middle inside the collection chamber 1 is inclined along the inner wall of the collection chamber 1 towards the discharge port 31, allowing the residual material to slide down the inclined surface to the discharge port 31 using gravity. The bottom of the collection chamber 1 is connected to a negative pressure pump 41 via a negative pressure pipe 4, which generates negative pressure suction to draw the residual material falling to the discharge port 31 into a designated channel. This achieves effective blocking, guiding, and directional collection of residual material from the sprue, reducing splashing and scattering, improving collection efficiency, and making the collection process more orderly.

[0033] In this embodiment, as Figure 1 As shown, a cleaning door 12 is installed on one side of the bottom of the collection chamber 1, and a base 13 is installed at the bottom of the collection chamber 1. The cleaning door 12 provides a passage for workers to enter the interior of the collection chamber 1, facilitating the cleaning of residual materials and debris inside the chamber; the base 13 increases the contact area between the equipment and the ground, enhances the stability of the equipment, facilitates daily maintenance and cleaning, ensures continuous and efficient operation of the equipment, and ensures that the equipment will not easily shake or tip over due to external forces during operation, thereby improving the safety of equipment operation.

[0034] Specifically, such as Figure 2As shown, the protective frame 2 includes a baffle 21, which is fixedly sleeved on the outside of the curtain 11. Several buffer pads 22 are installed on the inner wall of the baffle 21, and these buffer pads 22 abut against the outer wall of the curtain 11. The baffle 21 of the protective frame 2 provides support and protection for the curtain 11. The buffer pads 22 installed on the inner wall of the baffle 21 absorb the impact force and reduce the impact intensity when residual material splashes and hits the curtain 11, effectively reducing the impact damage to the curtain 11, extending the service life of the curtain 11, reducing equipment maintenance costs, and enhancing the protective performance of the equipment.

[0035] Furthermore, such as Figure 3 As shown, the negative pressure port of the negative pressure pipe 4 is located below the discharge port 31, and a protective net 42 is installed at the top of the negative pressure port end of the negative pressure pipe 4. Because the negative pressure port of the negative pressure pipe 4 is located below the discharge port 31, it can accurately generate suction for the residual material falling to this location. The protective net 42 can prevent larger residual materials or debris from entering the negative pressure pipe 4, avoiding pipe blockage, ensuring stable operation of the negative pressure system, preventing suction reduction or equipment failure due to blockage, and ensuring the continuity of residual material collection at the sprue.

[0036] Furthermore, such as Figure 1 As shown, the protective net 42 adopts a conical structure, and the material falling from the discharge port 31 slides to the side through the inclined surface of the conical structure. By adopting a conical structure, the inclined surface of the protective net 42 can change the direction of movement of the material falling from the discharge port 31, allowing the material to slide sideways along the inclined surface, avoiding direct accumulation at the negative pressure port, further reducing the risk of residual material clogging the negative pressure port, ensuring that the negative pressure suction can continuously and effectively act on the residual material, and improving collection efficiency and equipment operation stability.

[0037] Furthermore, such as Figure 1 As shown, the aperture size of the protective net 42 is smaller than the width of the sprue residue. By restricting the residue from entering the negative pressure pipe 4 by its size, only small debris that meets the size requirements can pass through, while the main sprue residue is blocked outside. This fundamentally prevents the sprue residue from entering the negative pressure pipe 4 and causing blockage, ensuring the smooth flow of the negative pressure system and providing a guarantee for the normal operation of the equipment.

[0038] Furthermore, such as Figure 3 As shown, several silicone pads 32 for cushioning are installed on the inner surface of the guide plate 3. The silicone pads 32 are elastic. When the residual material falls and hits the guide plate 3, the pads 32 can buffer the impact force, reduce the collision force on the residual material, reduce the risk of damage caused by the collision, and at the same time reduce the noise generated by the impact, making the collection process more stable and quiet.

[0039] Furthermore, the inner wall surface of the collection bin is coated with a wear-resistant coating. The wear-resistant coating has high hardness and wear resistance, which can effectively resist friction and impact during the falling of residual material, extend the service life of the collection bin 1, reduce the frequency of maintenance or replacement due to wear of the inner wall, reduce equipment maintenance costs, and ensure long-term stable operation of the equipment.

[0040] When the sprue residue collection device of this utility model is in use, after the injection molding machine robot removes the sprue at a high position, the sprue residue falls, and the top opening of the collection bin 1 allows the residue to smoothly enter the bin. At this time, the baffles 11 on the top of the four side walls of the collection bin 1 prevent the residue from splashing in all directions, while the protective frame 2 on the outside of the baffles 11, especially the buffer pad 22 on the inner wall of the baffle 21, further absorbs the impact force when the residue hits the baffles 11, preventing damage to the baffles 11 and initially limiting the movement range of the residue.

[0041] The remaining material entering the collection bin 1 falls onto the guide plate 3. Since the guide plate 3 is inclined along the inner wall of the collection bin 1 towards the discharge port 31, the remaining material slides along the surface of the guide plate 3 towards the discharge port 31 in the middle under its own gravity. During this process, the silicone pad 32 on the inner surface of the guide plate 3 buffers the impact force of the falling and sliding of the remaining material, reducing the damage of the remaining material and the generation of noise.

[0042] After the residual material slides to the discharge port 31, it falls. At this time, the negative pressure pump 41 is turned on. The aperture size of the protective net 42 is smaller than the width of the residual material at the water outlet, and it adopts a conical structure to prevent the residual material from entering the negative pressure pipe 4 and causing blockage. At the same time, it guides the residual material to slide along the conical inclined surface to ensure that the negative pressure suction can continue to act on the residual material, so that the residual material can be smoothly sent to the collection bin 1.

[0043] After the equipment has been running for a period of time, staff can enter the chamber by opening the cleaning door 12 to clean up any remaining material and debris. The base 13 at the bottom of the collection chamber 1 provides stable support for the equipment, ensuring that the equipment remains stable during operation and maintenance. The wear-resistant coating on the inner wall of the collection chamber 1 resists the friction and impact of the remaining material during long-term use, extending the service life of the equipment.

[0044] Finally, it should be noted that the electronic components in the negative pressure pump 41 and other components in this embodiment are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires. The specific connection method should refer to the working order between each electrical component in the above working principle to complete the electrical connection. All of these are technologies known in the art.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
