Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, and particularly relates to a material collecting device used in the production of building block toys. Background Art

[0002] Building block toys are usually plastic solid toys that can be arranged in different ways to form various building forms. Building block toys play a great role in the intellectual development of children and are also a way to improve children's hand-eye coordination ability. The production of building block toys usually adopts the injection molding method. In the whole set of fully automatic injection molding production equipment, a supporting manipulator is used to assist in demolding and transporting the building block toys. At present, due to the use of a special demolding device to improve the demolding efficiency of building block toys, there is no need for a relatively costly manipulator to assist in demolding. After demolding, the building block toys will directly fall into the box, and manual labor is required to control the weight and pack them, which instead increases the labor cost. Moreover, when the building block toys fall from a height, due to the instability of the demolding device, the building block toys will deviate from the box, or when the building block toys are stacked relatively high, collisions will cause the building block toys to fall out of the box, resulting in building block toys scattered around the injection molding equipment. Therefore, after overcoming the technical difficulty of demolding, it is necessary to redesign the material collecting device to collect and transport the demolded building block toys, while ensuring the smooth collection of building block toys and reducing the labor cost. Summary of the Utility Model

[0028] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined invention purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features, and effects of the present utility model as follows.

[0029] As Figures 1-8 shown, a receiving device used in the production of building block toys includes a longitudinal conveying mechanism, a sliding plate 5, a guiding plate 6, and a receiving box 7. Baffles 4 are provided on both sides of the longitudinal conveying mechanism to enclose both sides of the longitudinal conveying mechanism and prevent the building block toys from rolling off from the side. The sliding plate 5, the guiding plate 6, and the receiving box 7 are all installed between the baffles 4. An upwardly narrowing flared opening 13 is formed between the upper part of the sliding plate 5 and the guiding plate 6 for the building block toys to pass through. The lower part of the sliding plate 5 extends in an arc shape above the longitudinal conveying mechanism. After passing through the flared opening 13, the building block toys slide along the sliding plate 5, fly off from the end of the sliding plate 5, and fall onto the longitudinal conveying mechanism. The receiving box 7 is a rectangular frame that narrows from top to bottom and is used to receive the building block toys demolded from the injection molding equipment to prevent them from falling out of the device. The lower end of the receiving box 7 extends into the flared opening 13, and the building block toys are collected onto the longitudinal conveying mechanism through the receiving box 7 and the flared opening 13.

[0030] In the above embodiment, the upper part of the sliding plate 5 is vertically arranged, and the lower end of the material receiving box 7 is located on the side of the guiding plate 6. After the building block toys are received by the material receiving box 7, they slide along the guiding plate 6 to the side of the sliding plate 5 and fall from the flared opening 13. The whole movement process is smooth, avoiding the building block toys from falling vertically and passing through the flared opening 13, rolling at a relatively high speed and rushing out of the baffles 4 on both sides of the longitudinal conveying mechanism. The baffle 4 is provided with a sliding groove 401, and both ends of the guiding plate 6 and the material receiving box 7 are slidably connected in the sliding groove 401, and the positions of the guiding plate 6 and the material receiving box 7 can be adjusted; when the guiding plate 6 is longitudinally adjusted, the width of the flared opening 13 can be adjusted to adapt to the size of the building block toys, ensuring that the building block toys are properly blocked and buffered when passing through the flared opening 13, forcing the building block toys to start falling from the lower end of the flared opening 13, reducing their gravitational potential energy, and enabling them to just rush out of the sliding plate 5 after falling along the sliding plate 5, avoiding the building block toys from tumbling and bouncing over the baffle 4 due to excessive gravitational potential energy; when the material receiving box 7 is longitudinally adjusted, the distance between its lower end and the guiding plate 6 can be adjusted to ensure that the building block toys entering from above the material receiving box 7 can be accurately placed on the guiding plate 6, and the guiding plate 6 guides the building block toys to the lower end of the flared opening 13, thereby ensuring the normal use of the above-mentioned blocking and buffering functions.

[0031] In the above embodiment, a connecting plate 8 is provided between the baffles 4. The connecting plate 8 is located on the side of the guiding plate 6 outside the flared opening 13. The connecting plate 8 is provided with a threaded hole 801, and a first lead screw 9 is threadedly connected in the threaded hole 801. One end of the first lead screw 9 is rotatably connected to the guiding plate 6. By rotating the first lead screw 9, the position of the guiding plate 6 can be accurately adjusted, thereby accurately adjusting the width of the flared opening 13 and the blocking and buffering effects of the flared opening 13. Moreover, after adjustment by screw transmission, the first lead screw 9 is not easy to rotate, and the position of the guiding plate 6 remains unchanged; one end of the first lead screw 9 is rotatably connected to the guiding plate 6 through a bearing 10, reducing the transmission friction force and making the longitudinal movement of the guiding plate 6 smoother. The sliding plate 5 is provided with a through hole, and the side of the material receiving box 7 is provided with a second lead screw 11. Two nuts 12 are threadedly connected to the second lead screw 11. The second lead screw 11 passes through the through hole, and the two nuts 12 are respectively located on both sides of the sliding plate 5; after the position of the guiding plate 6 is adjusted, the material receiving box 7 is moved to abut against one end of the first lead screw 9 of the guiding plate 6, and then the second lead screw 11 is locked by the two nuts 12 to fix the position of the material receiving box 7, ensuring that the material receiving box 7 does not shift and accurately placing the building block toys at the starting position on the guiding plate 6, making full use of the stroke of the guiding plate 6 to block and buffer the building block toys, and also ensuring the normal use of the blocking and buffering functions of the flared opening 13.

[0032] In the above embodiment, the longitudinal conveying mechanism includes a first frame 1, a longitudinal conveyor belt 3 and a first motor 2. The longitudinal conveyor belt 3 and the baffle 4 are respectively installed on the first frame 1. The baffle 4 is located on both sides of the longitudinal conveyor belt 3. The first motor 2 is installed on the side of the baffle 4. The output end of the first motor 2 passes through the baffle 4 and is in transmission connection with the longitudinal conveyor belt 3. The surface layer of the longitudinal conveyor belt 3 is made of rubber material, which can provide frictional force for the building block toys to decelerate and provide buffering force to avoid wear. In addition, the device further includes a transverse conveying mechanism and a storage box 23. The transverse conveying mechanism is arranged below the end of the longitudinal conveying mechanism. The transverse conveying mechanism is perpendicular to the conveying direction of the longitudinal conveying mechanism. The storage box 23 is placed at the upper end of the transverse conveying mechanism. The storage box 23 can be horizontally conveyed to the lower part of the end of the longitudinal conveying mechanism to catch the building block toys falling from the longitudinal conveyor belt 3, and then be packed and sealed. First position sensors 14 and second position sensors 15 are respectively arranged on both sides of the first frame 1. The first position sensors 14 and the second position sensors 15 face above the transverse conveying mechanism. The first position sensors 14 and the second position sensors 15 can be simultaneously aligned with the side of the storage box 23 to judge the position of the storage box 23. When the storage box 23 is full and needs to be replaced, the first motor 2 stops driving. After the new storage box 23 triggers both the first position sensor 14 and the second position sensor 15 at the same time, the first motor 2 continues the longitudinal conveying.

[0033] In the above embodiment, the lateral conveying mechanism includes a second frame 16, a lateral conveyor belt 19, and a second motor 17. The lateral conveyor belt 19 is installed on the second frame 16. A guardrail 18 is provided on the second frame 16. The guardrail 18 is located on both sides of the lateral conveyor belt 19. The second motor 17 is installed on the side of the guardrail 18. The output end of the second motor 17 passes through the guardrail 18 and is in driving connection with the lateral conveyor belt 19. The storage bin 23 is located between the guardrails 18, ensuring that the storage bin 23 does not deviate and can be accurately conveyed to the designated position, and ensuring that the building block toys accurately fall into the storage bin 23. A weighing mechanism is provided at the lower end of the second frame 16. The weighing mechanism is electrically connected to the second motor 17, the first position sensor 14, and the second position sensor 15. The weighing mechanism can pass upward through the second frame 16 and the lateral conveyor belt 19 and abut against the storage bin 23; the weighing mechanism measures the overall weight of the storage bin 23 in real time. After the storage bin 23 is loaded to a certain weight, the second motor 17 is timely driven to replace the storage bin 23, ensuring the normal operation of the storage of the building block toys. The weighing mechanism includes a cylinder 20, a support plate 21, and a weighing device 22. The weighing device 22 is a commonly used commercially available industrial weighing device. The cylinder 20 is installed at the lower end of the second frame 16. The output end of the cylinder 20 faces upward and is connected to the support plate 21. The weighing device 22 is installed on the support plate 21. The weighing device 22 can support the storage bin 23 upward and lift the storage bin 23 from the lateral conveyor belt 19 to ensure the accuracy of weighing; the cylinder 20, the weighing device 22, the motor, the first position sensor 14, and the second position sensor 15 are electrically connected, and the components cooperate with each other for linkage to ensure the orderly progress of the work. Handles 2301 are provided on both sides of the storage bin 23, facilitating the operation of the staff.

[0034] Description of the working mode of the present utility model:

[0035] Install this device at the demoulding and discharging position of the injection molding equipment. Rotate the first lead screw 9 according to the injected building block toys, so as to adjust the distance between the guide plate 6 and the sliding plate 5, and then adjust the width of the flared opening 13 to adapt to the size of the building block toys. Adjust until the building block toys can pass smoothly at the flared opening 13. At the same time, under the blocking and buffering action of the flared opening 13, the building block toys stay briefly and then pass through the flared opening 13, and slide and fall onto the longitudinal conveyor belt 3 through the sliding plate 5. The building block toys located on the longitudinal conveyor belt 3 are gradually conveyed to the transverse conveying mechanism at the end of the longitudinal conveyor belt 3 under the drive of the first motor 2, and accurately fall into the storage bin 23. Under the real-time weighing of the weighing device 22, the storage bin 23 is replaced in time. During this process, the first position sensor 14 and the second position sensor 15 are aligned with the side of the storage bin 23. When replacing the storage bin 23, the first motor 2 stops driving the longitudinal conveyor belt 3, and the air cylinder 20 controls the weighing device 22 to descend. The transverse conveyor belt 19 undertakes and conveys the storage bin 23 to the end, and the new storage bin 23 is placed at the designated position, that is, the position aligned by the first position sensor 14 and the second position sensor 15. Triggering both position sensors is regarded as in place. Immediately afterwards, the air cylinder 20 pushes the weighing device 22 to lift the storage bin 23 upwards. Finally, the first motor 2 drives the longitudinal conveyor belt 3 to continue conveying the building block toys, realizing the entire material collection and transfer process of the building block toys.
