Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of injection molding, and in particular to a machine for separating and screening injection molding products and material heads. Background Art
[0002] After the injection molding product is completed, the slug and the finished product need to be screened and separated. The common discharging method of injection molding machines on the market is to eject the slug and the product together and then sort them manually or by other means. This method has relatively high production capacity, but other costs will be invested in subsequent sorting. The other method is that after the injection molding machine opens the mold, the robot reaches into the mold to grab the product and take it out, and the slug is directly ejected. This method has a high degree of automation, but the action of the robot reaching in and retracting increases the production cycle of each mold of the equipment. Utility Model Content
[0003] In order to solve the above technical problems, the utility model provides an injection molding product and material head separation screening machine, which realizes the automatic screening and separation of injection molding products and material heads, has a simple structure, low cost and high efficiency.
[0004] Specifically, the utility model discloses a machine for separating and screening injection molded products and material heads, comprising:
[0005] The material receiving and transporting line is used to receive and transport the injection molded products and material heads discharged from the injection molding machine;
[0006] A screening conveyor line is connected to the material receiving conveyor line, and comprises a screening mechanism, a driving mechanism and a vibrating mechanism. The screening mechanism comprises a frame and a mesh screening chain arranged on the frame. The mesh screening chain rotates under the driving of the driving mechanism, and the vibrating mechanism contacts the mesh screening chain.
[0007] The discharge transport line, including the discharge runner, is used to transport the screened injection molded products.
[0008] The benefit of adopting the above technical solution is that it can realize automatic screening of injection molded products and slugs, directly connect with the injection molding machine, shorten the production cycle of each mold, improve production capacity, low cost and high efficiency.
[0009] Furthermore, the material receiving and transporting line includes: a flat belt line, a material receiving rack, and a height and angle adjustment mechanism, and the height and angle adjustment mechanism is arranged on the lower side of the flat belt line and connected to the material receiving rack.
[0010] The advantage of adopting the above technical solution is that the height and position adjustment mechanism is used to connect with injection molding equipment of different heights, and at the same time, the angle of the transport line can be changed to facilitate connection with the screening conveyor line.
[0011] Furthermore, a material receiving baffle and a material guide plate are arranged on the upper side of the flat belt line, the material receiving baffle surrounds the end of the flat belt line close to the injection molding machine, and the material guide plate is arranged obliquely.
[0012] The benefit of adopting the above technical solution is that the material receiving and transporting line receives the products and stubs after the injection molding machine is completed. The setting of the material receiving baffle can prevent the injection molded products and stubs from falling to the outside of the material receiving and transporting line, thereby improving the accuracy of material receiving.
[0013] Furthermore, the mesh screening chain is provided with a plurality of drop holes for accommodating the injection molded products to pass through.
[0014] The benefit of adopting the above technical solution is that the blanking hole is set for the injection molded products to pass through. Since the material head is large in size and cannot pass through, the injection molded products and the material head can be separated and screened. At the same time, some injection molded products that are too large and unqualified will not pass through the blanking hole, thereby achieving preliminary separation of defective products and improving the efficiency of subsequent product inspection.
[0015] Furthermore, the vibration mechanism includes a vibration motor and a vibration wheel, the vibration motor drives the vibration wheel to rotate, the vibration wheel is provided with protrusions protruding to both sides, and the vibration wheel is arranged in contact with the mesh screening chain.
[0016] The benefit of adopting the above technical solution is that the vibration motor drives the vibration cam to rotate. When the protrusion of the vibration wheel contacts the mesh screening chain during rotation, the mesh screening chain is pushed upward, and then the vibration wheel continues to rotate and the protrusion rotates to the side. At this time, the mesh screening chain falls back to realize the vibration function. The vibration wheel completes two vibrations for each rotation of the vibration wheel.
[0017] Furthermore, the discharge channel includes: a transport belt, which is arranged at the lower side of the upper mesh screening chain, and the transport direction of the transport belt is perpendicular to the transport direction of the mesh screening chain.
[0018] The advantage of adopting the above technical solution is that, since the mesh screening chain is ring-shaped, separation and screening are performed on the upper layer, and the injection molded products fall to the conveyor belt for transportation, and the separation efficiency is high.
[0019] Furthermore, the discharging transport line also includes a material collection baffle, which is symmetrically arranged on the upper side of the transport belt.
[0020] The benefit of adopting the above technical solution is that the aggregate baffle allows the injection molded products scattered and dropped on the discharge conveyor line to be concentrated in the middle of the conveyor line, which is convenient for transportation.
[0021] Furthermore, the height and angle adjustment mechanism includes lifting plates arranged at the four corners of the material receiving frame, the top of the lifting plate is connected to the flat belt line, and the side of the lifting plate is provided with vertically arranged strip holes.
[0022] The benefit of adopting the above technical solution is that the height adjustment is achieved by controlling the position of the lifting plate, and then moving the lifting plates on both sides of the same end to control the pitch angle of the entire flat belt line. The setting of the strip holes facilitates connection with the profiles on the material receiving rack.
[0023] Furthermore, a transfer plate is provided at the end of the material receiving and transporting line, and the transfer plate connects the material receiving and transporting line and the screening conveying line.
[0024] The benefit of adopting the above technical solution is that the setting of the transfer plate ensures that all injection molded products and material heads enter the screening conveyor line for screening, thereby ensuring processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0032] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0033] like Figure 1-4 As shown, the utility model discloses a machine for separating and screening injection molded products and material heads, comprising:
[0034] Material receiving and transporting line 1 is used to receive and transport the injection molded products and material heads discharged from the injection molding machine, and one end is connected to the discharge port of the injection molding machine;
[0035] The screening conveyor line 2 is connected to the material receiving conveyor line 1, and includes a screening mechanism, a driving mechanism 21 and a vibrating mechanism. The screening mechanism includes a frame 22 and a mesh screening chain 23 arranged on the frame 22. The mesh screening chain 23 rotates under the drive of the driving mechanism 21, and the vibrating mechanism contacts the mesh screening chain 23. An electric control box is arranged at the end of the screening conveyor line 2 to control the speed of transportation and screening.
[0036] The discharge transport line, including a discharge flow channel 3, is used to transport the screened injection molded products.
[0037] The benefit of adopting the above technical solution is that it can realize automatic screening of injection molded products and slugs, directly connect with the injection molding machine, shorten the production cycle of each mold, improve production capacity, low cost and high efficiency.
[0038] In some embodiments, the material receiving and transporting line 1 includes: a flat belt line 11, a material receiving rack 12, and a height and angle adjustment mechanism 13. The height and angle adjustment mechanism 13 is arranged on the lower side of the flat belt line 11 and connected to the material receiving rack 12. The material receiving rack 12 is a profile rack that plays a supporting role. The flat belt line 11 is driven to rotate by a motor to transport the injection molded products and the material heads to the screening conveyor line.
[0039] The height and position adjustment mechanism is used to connect with injection molding equipment at different heights, and can also change the angle of the transport line to facilitate connection with the screening conveyor line 2.
[0040] In some embodiments, a material receiving baffle 111 and a material guide plate 112 are provided on the upper side of the flat belt line 11. The material receiving baffle 111 surrounds the end of the flat belt line 11 close to the injection molding machine. The material receiving baffle 111 is connected to the material guide plate 112 and is inclined. A fixed plate 113 is also provided on the side of the flat belt line 11 opposite to the material guide plate 112. A gradually shrinking outlet is formed between the material guide plate 112 and the fixed plate 113, which plays the role of gathering the injection molded products and the material heads, and can prevent the injection molded products and the material heads from falling to the outside of the material receiving and transporting line 1, thereby improving the accuracy of material receiving.
[0041] In some embodiments, the mesh screening chain 23 is provided with a plurality of drop holes 231 for accommodating the injection molded products to pass through, and is driven to rotate by a motor and a sprocket.
[0042] The drop hole 231 is set for the injection molded products to pass through. Since the material head is too large, it cannot pass through, thereby realizing the separation and screening of the injection molded products and the material head. At the same time, some injection molded products that are too large and unqualified will not pass through the drop hole 231, and will fall into the defective product box from the end of the mesh screening chain 23, thereby realizing the preliminary separation of defective products and improving the efficiency of subsequent product inspection.
[0043] In some embodiments, the vibration mechanism includes a vibration motor 24 and a vibration wheel 25. The vibration motor 24 drives the vibration wheel 25 to rotate. The vibration wheel 25 is provided with protrusions 251 protruding to both sides and arranged in contact with the mesh screening chain 23. The vibration wheel 25 is symmetrically arranged and driven to rotate together by a transmission shaft.
[0044] The vibration motor 24 drives the vibration cam to rotate. When the protrusion 251 of the vibration wheel 25 contacts the mesh screening chain 23 during the rotation, the mesh screening chain 23 is pushed upward, and then the vibration wheel 25 continues to rotate, and the protrusion 251 rotates to the side. At this time, the mesh screening chain 23 falls back to realize the vibration function. The vibration wheel 25 completes two vibrations for each rotation. The vibration wheel 25 rotates continuously and vibrates continuously, which speeds up the screening while preventing the injection molded products and the material heads from being stuck in the blanking hole 231.
[0045] In some embodiments, the discharge channel 3 includes: a transport belt 31, which is arranged on the lower side of the upper mesh screening chain 23, and the transport direction of the transport belt 31 is perpendicular to the transport direction of the mesh screening chain 23. A good product receiving box is arranged on the lower side of the end of the transport belt 31 for receiving good products.
[0046] Since the mesh screening chain 23 is annular, it continuously screens and separates during the rotation process, and is located at the upper layer for separation and screening, and the injection molded products fall to the conveyor belt 31 for transportation, and the separation efficiency is high.
[0047] Furthermore, the discharge transport line further includes a collection baffle 32, which is symmetrically arranged on the upper side of the transport belt 31. The collection baffle 32 allows the injection molded products scattered and dropped on the discharge transport line to be concentrated in the middle of the transport line for easy transportation.
[0048] In some embodiments, the height and angle adjustment mechanism 13 includes lifting plates 131 arranged at the four corners of the material receiving rack 12, with a total of four lifting plates 131. The top of each lifting plate 131 is fixedly connected to the flat belt line 11, and the side of the lifting plate 131 is provided with vertically arranged strip holes.
[0049] The height adjustment is achieved by controlling the position of the lifting plate 131, and then moving the lifting plates 131 on both sides of the same end to control the pitch angle of the entire flat belt line 11 and connect the screening conveyor lines 2 at different heights. The setting of the strip holes facilitates the connection with the profiles on the receiving rack 12.
[0050] Furthermore, a transfer plate 14 is provided at the end of the material receiving and transporting line 1, and the transfer plate 14 connects the material receiving and transporting line 1 and the screening conveying line 2. The transfer plate 14 is connected to both sides of the material receiving and transporting line 1 through two side connecting plates. The setting of the transfer plate 14 ensures that all injection molded products and material heads enter the screening conveying line 2 for screening, thereby ensuring processing efficiency.
[0051] During the working process, after the injection molded products and the material heads are ejected from the injection molding machine, they fall directly onto the material receiving and conveying line 1. The material receiving and conveying line 1 conveys the injection molded products and the material heads to the screening conveying line 2. At this time, the products smaller than the blanking hole 231 will fall to the discharge conveying line, and the material heads larger than the blanking hole 231 will be conveyed to the end of the mesh chain through the mesh screening chain 23 and fall freely. At the same time, the vibration wheel 25 continuously vibrates the mesh screening chain 23, so that the stacked or stuck injection molded products shake and are more likely to fall into the discharge conveying line, thereby improving the overall screening efficiency. The whole process does not involve the robot, shortening the production cycle of each mold and improving production capacity. The screening is carried out by the difference in the size of the material heads and the injection molded products. The screening is fully automatic, without the participation of the sorting equipment or manpower in the later stage, saving costs.
[0052] For ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the utility model, which all fall within the protection scope of the utility model.
