Description

TECHNICAL FIELD

[0001] The application relates to the technical field of toothbrush manufacturing, and particularly relates to a polyethylene toothbrush handle production injection molding all-in-one machine. BACKGROUND

[0002] A toothbrush is a cleaning product, which is a handle type brush, is used for adding toothpaste on the brush, and then repeatedly brushes each part of the tooth, and the earliest toothbrush originates from China. At present, the types of toothbrushes are particularly various, including adult toothbrushes, children's toothbrushes and electric toothbrushes. The toothbrushes need to use an injection molding all-in-one machine during production and manufacturing. The working principle of the injection molding machine is similar to that of a syringe for injection. The injection molding machine is used for injecting the plastic in a molten state (i.e. in a viscous flow state) into a closed mold cavity by means of the pushing force of a screw (or a plunger), and the product is obtained after solidification and setting.

[0003] When the mechanical hand takes out the toothbrush handle, the toothbrush handle is cut, and the cut toothbrush handle is conveyed and collected through a conveying belt. The existing collection mode is to directly place a material collecting box below the end of the conveying belt. The toothbrush handle falls into the material collecting box after being conveyed through the conveying belt. However, the toothbrush handles falling into the material collecting box are randomly stacked, the space utilization rate of the material collecting box is low, manual arrangement is needed to stack the toothbrush handles neatly, and the material collecting box needs to be manually replaced in time after being filled with the toothbrush handles, which is time-consuming and labor-consuming. Therefore, the polyethylene toothbrush handle production injection molding all-in-one machine is provided to solve the above problems. SUMMARY

[0004] The application aims to provide a polyethylene toothbrush handle production injection molding all-in-one machine to solve the problems in the background.

[0005] To achieve the above-mentioned purpose, the application provides the following technical scheme.

[0006] A polyethylene toothbrush handle production injection molding all-in-one machine, comprising a rack, an injection molding device and a conveying assembly, wherein the upper end of the rack is provided with an injection molding device, the left end of the injection molding device is provided with an injection molding device, the injection molding device is provided with a taking-out mechanical hand, the front side of the rack is provided with a conveying belt, the conveying belt is provided with a support, the upper end of the support is provided with a plurality of first fixing frames, the first fixing frames are provided with fans, the support is provided with a fixed plate, the lower end of the fixed plate is provided with a plurality of guide strips matched with the conveying belt, the left end of the support is provided with a second fixing frame, the second fixing frame is provided with a guide plate matched with the guide strips, and the lower side of the guide plate is provided with a material collecting box.

[0007] The conveying assembly, the lower side of the material collecting box is provided with a bottom plate, the upper end of the bottom plate is provided with a conveying assembly matched with the material collecting box, and the conveying assembly is used for automatically conveying the material collecting box after the material collecting box is filled with materials.

[0008] A blocking component is provided on the second fixing frame corresponding to the guide strip. The blocking component is used to close the guide strip when changing the receiving box.

[0009] When collecting toothbrush handles, a receiving box is placed on the transport component. The injection-molded and cut toothbrush handles fall onto the conveyor belt for transport. Guide bars facilitate separation and restrict the movement path of the toothbrush handles. During the movement, a fan is activated to cool the toothbrush handles. When the toothbrush handles move to the guide plate, the guide plate further restricts their fall path, allowing them to fall into the receiving slot within the receiving box. The receiving slot structure, formed by the guide bars, guide plate, and partitions, ensures that the toothbrush handles are stacked neatly during collection, preventing them from being placed haphazardly in the receiving box and improving its utilization rate. At the same time, the transport component facilitates automatic replacement and transport of the receiving box, saving labor, time, and effort.

[0010] As a further embodiment of the present invention, the transport assembly includes a first transport plate, a support plate, and a second transport plate. The lower end of the receiving box is attached to the support plate, and telescopic rods are provided at the four corners of the lower end of the support plate. The lower ends of the telescopic rods are fixedly connected to the base plate. The left end of the support plate is attached to the first transport plate, and the four corners of the lower end of the first transport plate are provided with first fixing posts fixedly connected to the base plate. The right end of the support plate is attached to the second transport plate, and the upper end of the second transport plate is lower than the lower end of the support plate. The four corners of the lower end of the second transport plate are provided with second fixing posts fixedly connected to the base plate. Receiving boxes are placed on both the first transport plate and the support plate. Toothbrush handles fall into the receiving boxes on the support plate. The second transport plate is used to transport the receiving boxes filled with toothbrush handles.

[0011] As a further embodiment of the present invention, a support frame is attached to the left end of the base plate, and a limiting block is provided at the right end of the support frame. The limiting block is slidably connected to the base plate, and a limiting groove is provided at the left end of the base plate corresponding to the limiting block. A first threaded rod is threadedly connected to the support frame. A motor is provided at the rear end of the first threaded rod, and a mounting plate fixedly connected to the base plate is provided at the lower end of the motor. A bearing seat fixedly connected to the base plate is provided at the front end of the first threaded rod. By starting the motor, the first threaded rod is driven to rotate, thereby driving the support frame to move forward. The limiting block and limiting groove structure facilitates the limiting of the support frame and prevents the support frame from rotating on its own as the first threaded rod rotates.

[0012] As a further embodiment of the present invention, the right end of the support frame is provided with a first electric telescopic rod, the right end of the first electric telescopic rod is provided with a connecting plate, and the right end of the connecting plate is symmetrically provided with first push blocks corresponding to the front and rear of the receiving box. When the support frame moves forward, the support frame drives the first electric telescopic rod, the connecting plate and the first push blocks to move forward. The first push blocks thus push the receiving box full of toothbrush handles forward to the second transport plate, and at the same time push the empty receiving box to move below the guide plate, thereby realizing the automatic replacement and transport of the receiving box.

[0013] As a further embodiment of the present invention, a fixed block is provided at the upper end of the first push block on the front side, and a second push block is slidably connected to the front end of the fixed block. A second electric telescopic rod is provided at the rear end of the second push block, which passes through the fixed block. A first mounting bracket is provided at the rear end of the second electric telescopic rod, which is fixedly connected to the fixed block. By activating the second electric telescopic rod, the second push block is driven to move forward, thereby pushing the receiving box forward, thereby moving the uncollected material in the receiving box to the area directly below the guide plate, so that the receiving box can continue to collect the toothbrush handle.

[0014] As a further embodiment of the present invention, a first spring is fitted onto the telescopic rod. The upper end of the first spring is fixedly connected to the support plate, and the lower end of the first spring is fixedly connected to the base plate. A first switch is provided at the lower end of the support plate, and a second switch is provided at the upper end of the base plate corresponding to the support plate. The elastic potential energy of the first spring facilitates the provision of support force to the support plate. When the toothbrush handle falls into the collection box, the weight of the collection box gradually increases, causing the collection box to move downwards along with the support plate and the first switch. The first switch then contacts and opens the base plate. At this time, the second electric telescopic rod is activated, driving the second pusher block forward. The second pusher block then pushes the collection box forward. This process moves the uncollected toothbrush handles in the receiving bin to directly below the guide plate. Then, the third electric telescopic rod is activated to return the baffle to its original position, allowing the receiving bin to continue collecting toothbrush handles. When the receiving bin is full of toothbrush handles, the support plate is level with the second transport plate, and the support plate contacts and opens the second switch. At this point, the first electric telescopic rod is activated, moving the connecting plate and the first push block to the right. The first push block then pushes the receiving bin full of toothbrush handles forward onto the second transport plate, while simultaneously pushing the empty receiving bin to below the guide plate. This achieves automatic replacement and transport of the receiving bin, saving labor, time, and effort.

[0015] As a further embodiment of the present invention, the blocking assembly includes a baffle, a third electric telescopic rod, and a second mounting bracket. The second mounting bracket is provided at the left end of the second mounting bracket, and the third electric telescopic rod is provided at the right end of the second mounting bracket. The baffle is provided at the right end of the third electric telescopic rod corresponding to the guide strip. By activating the third electric telescopic rod, the baffle is driven to move to the right, thereby closing the guide strip and preventing the toothbrush handle inside the guide strip from falling off when adjusting or replacing the collection box.

[0016] As a further embodiment of the present invention, the receiving box is provided with a receiving groove through several partitions corresponding to the guide plate, and the right end of the receiving box is provided with a discharge port corresponding to the receiving groove. The receiving groove is provided with a discharge component, and the inner wall of the discharge port is provided with a limiting component. The receiving groove structure formed by the set guide plate and partitions makes it easy for the toothbrush handles to be stacked neatly when collecting materials, and avoids the toothbrush handles being placed haphazardly in the receiving box.

[0017] As a further embodiment of the present invention, the discharge assembly includes a push plate, and the receiving trough is provided with the push plate. The left end of the push plate is provided with a connecting rod that penetrates the receiving box, and the other end of the connecting rod is provided with a horizontal plate. The horizontal plate is threadedly connected to a second threaded rod. One end of the second threaded rod is provided with a bearing that is fixedly connected to the receiving box, and the other end of the second threaded rod is provided with a handle. When it is necessary to remove the toothbrush handle from the receiving box, rotating the handle drives the second threaded rod to rotate. The second threaded rod thereby drives the horizontal plate, the connecting rod and the push plate to move, and the push plate thereby pushes the toothbrush handle in the receiving trough toward the discharge port.

[0018] As a further embodiment of the present invention, the limiting component includes a groove, a limiting plate, and a second spring. The inner wall of the discharge port is provided with a groove, and the limiting plate is slidably connected in the groove. The limiting plate is in the shape of a right trapezoid. A plurality of second springs are provided in the groove. One end of the second spring is fixedly connected to the inner wall of the groove, and the other end of the second spring is fixedly connected to the limiting plate. When the toothbrush handle contacts the limiting plate, the toothbrush handle continues to move, causing the two limiting plates to move away from each other. The limiting plate compresses the second spring, thereby facilitating the removal of the toothbrush handle from the receiving box.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In use, a receiving box is placed on the transport assembly. The injection-molded and cut toothbrush handles fall onto the conveyor belt for transport. The guide strips facilitate separation and restrict the movement path of the toothbrush handles. During the movement, a fan is activated to cool the toothbrush handles. When the toothbrush handles move to the guide plate, the guide plate restricts the path of the toothbrush handles as they fall into the receiving trough inside the receiving box. The receiving trough structure formed by the guide strips, guide plate, and partitions facilitates the neat stacking of toothbrush handles during collection, preventing them from being placed haphazardly in the receiving box and improving the utilization rate of the receiving box.

[0021] 2. The set transportation components facilitate the automatic replacement and transportation of receiving boxes, saving manpower, time and effort.

[0022] 3. When using this invention, if it is necessary to remove the toothbrush handle from the receiving box, the provided discharge component facilitates the movement of the toothbrush handle in the receiving trough toward the discharge port, thereby making it easy to remove the toothbrush handle from the receiving box.

[0036] Example

[0037] like Figure 1 and Figure 2 As shown in the embodiment of the present invention, a polyethylene toothbrush handle production injection molding machine includes a frame 1, an injection molding device 2, and a transport component 10. The upper end of the frame 1 is provided with an injection molding device 101, and the left end of the injection molding device 101 is provided with an injection molding device 2. The injection molding device 2 is provided with a take-out robot 201. The front side of the frame 1 is provided with a conveyor belt 3, and the conveyor belt 3 is provided with a support 301. The upper end of the support 301 is provided with a plurality of first fixed frames 4, and the first fixed frames 4 are provided with fans 5. The support 301 is provided with a fixed plate 601, and the lower end of the fixed plate 601 is provided with a plurality of guide strips 6 that are in contact with the conveyor belt 3. The left end of the support 301 is provided with a second fixed frame 7, and the second fixed frame 7 is provided with a guide plate 701 corresponding to the guide strips 6. The lower side of the guide plate 701 is provided with a receiving box 9.

[0038] The transport component 10 is provided on the lower side of the receiving box 9, and the upper end of the bottom plate 8 is provided with the transport component 10 corresponding to the receiving box 9. The transport component 10 is used for automatic transport when the receiving box 9 is full of materials.

[0039] The second fixing frame 7 is provided with a blocking component 11 corresponding to the guide strip 6. The blocking component 11 is used to close the guide strip 6 when the receiving box 9 is replaced.

[0040] Specifically, a receiving box 9 is placed on the transport component 10. The injection-molded and cut toothbrush handles fall onto the conveyor belt 3 for transport. The guide strips 6 facilitate separation and restrict the movement path of the toothbrush handles. During the movement of the toothbrush handles, the fan 5 is activated to cool them down. When the toothbrush handles move to the guide plate 701, the guide plate 701 restricts the path of the toothbrush handles as they fall into the receiving trough inside the receiving box 9. The receiving trough structure formed by the guide strips 6, guide plate 701, and partition 901 facilitates the neat stacking of toothbrush handles during collection, preventing them from being placed haphazardly in the receiving box 9 and improving the utilization rate of the receiving box 9. At the same time, the transport component 10 facilitates the automatic replacement and transport of the receiving box 9, saving labor, time, and effort.

[0041] like Figure 2As shown, the transport assembly 10 includes a first transport plate 1002, a support plate 1003, and a second transport plate 1005. The lower end of the receiving box 9 is attached to the support plate 1003. Telescopic rods 1006 are provided at the four corners of the lower end of the support plate 1003. The lower ends of the telescopic rods 1006 are fixedly connected to the base plate 8. The left end of the support plate 1003 is attached to the first transport plate 1002. The four corners of the lower end of the first transport plate 1002 are provided with first fixing posts 1001 fixedly connected to the base plate 8. The right end of the support plate 1003 is attached to the second transport plate 1005. The upper end of the second transport plate 1005 is lower than the lower end of the support plate 1003. The four corners of the lower end of the second transport plate 1005 are provided with second fixing posts 1004 fixedly connected to the base plate 8.

[0042] Specifically, receiving boxes 9 are placed on both the first transport plate 1002 and the support plate 1003. The toothbrush handles fall into the receiving boxes 9 on the support plate 1003. The second transport plate 1005 is used to transport the receiving boxes 9 filled with toothbrush handles.

[0043] like Figure 5 and Figure 7 As shown, a support frame 1013 is attached to the left end of the base plate 8, and a limiting block 1017 is provided at the right end of the support frame 1013. The limiting block 1017 is slidably connected to the base plate 8. A limiting groove 1018 is provided at the left end of the base plate 8 corresponding to the limiting block 1017. A first threaded rod 1014 is threadedly connected to the support frame 1013. A motor 1015 is provided at the rear end of the first threaded rod 1014. A mounting plate 1016 fixedly connected to the base plate 8 is provided at the lower end of the motor 1015, and a bearing seat 1019 fixedly connected to the base plate 8 is provided at the front end of the first threaded rod 1014.

[0044] Specifically, the motor 1015 drives the first threaded rod 1014 to rotate, which in turn drives the support frame 1013 to move forward. The limiting block 1017 and the limiting groove 1018 structure facilitate the limiting of the support frame 1013, preventing the support frame 1013 from rotating on its own as the first threaded rod 1014 rotates.

[0045] like Figure 4 and Figure 5 As shown, the support frame 1013 is provided with a first electric telescopic rod 1012 at the right end, and a connecting plate 1011 is provided at the right end of the first electric telescopic rod 1012. The connecting plate 1011 is provided with a first push block 1010 symmetrically arranged at the front and rear of the receiving box 9.

[0046] Specifically, by moving the support frame 1013 forward, the support frame 1013 drives the first electric telescopic rod 1012, the connecting plate 1011 and the first push block 1010 to move forward. The first push block 1010 then pushes the collection box 9 filled with toothbrush handles forward to the second transport plate 1005, and at the same time pushes the empty collection box 9 to move below the guide plate 701, thereby realizing the automatic replacement and transport of the collection box 9.

[0047] like Figure 4 As shown, a fixing block 1020 is provided at the upper end of the first push block 1010 on the front side. The front end of the fixing block 1020 is slidably connected to the second push block 1021. The rear end of the second push block 1021 is provided with a second electric telescopic rod 1022 that passes through the fixing block 1020. The rear end of the second electric telescopic rod 1022 is provided with a first mounting bracket 1023 that is fixedly connected to the fixing block 1020.

[0048] Specifically, by activating the second electric telescopic rod 1022, the second push block 1021 is driven to move forward. The second push block 1021 pushes the receiving box 9 forward, thereby moving the uncollected material in the receiving box 9 to directly below the guide plate 701, so that the receiving box 9 can continue to collect the toothbrush handle.

[0049] like Figure 7 As shown, a first spring 1007 is sleeved on the telescopic rod 1006. The upper end of the first spring 1007 is fixedly connected to the support plate 1003, and the lower end of the first spring 1007 is fixedly connected to the base plate 8. A first switch 1008 is provided at the lower end of the support plate 1003, and a second switch 1009 is provided at the upper end of the base plate 8 corresponding to the support plate 1003.

[0050] Specifically, the elastic potential energy of the first spring 1007 provides support for the support plate 1003. When the toothbrush handle falls into the receiving box 9, the weight of the receiving box 9 gradually increases. The receiving box 9 then drives the support plate 1003 and the first switch 1008 to move downwards. The first switch 1008 then contacts and opens the bottom plate 8. At this time, the second electric telescopic rod 1022 is activated, which drives the second push block 1021 to move forward. The second push block 1021 pushes the receiving box 9 forward, thereby moving the uncollected material in the receiving box 9 to directly below the guide plate 701. Then, the third electric telescopic rod 1102 is activated, which drives the baffle 110... 1. Return to its original position to facilitate the collection box 9 to continue collecting toothbrush handles. When the collection box 9 is full of toothbrush handles, the support plate 1003 is level with the second transport plate 1005. At the same time, the support plate 1003 contacts and opens the second switch 1009. At this time, the first electric telescopic rod 1012 is activated to drive the connecting plate 1011 and the first push block 1010 to move to the right. The first push block 1010 pushes the collection box 9 full of toothbrush handles forward to the second transport plate 1005, and at the same time pushes the empty collection box 9 to move below the guide plate 701, thereby realizing the automatic replacement and transportation of the collection box 9, saving manpower, time and effort.

[0051] like Figure 6 As shown, the blocking assembly 11 includes a baffle 1101, a third electric telescopic rod 1102, and a second mounting bracket 1103. The second mounting bracket 1103 is provided at the left end of the second fixed bracket 7, and the third electric telescopic rod 1102 is provided at the right end of the second mounting bracket 1103. The baffle 1101 is provided at the right end of the third electric telescopic rod 1102 corresponding to the guide strip 6.

[0052] Specifically, by activating the third electric telescopic rod 1102, the baffle 1101 is moved to the right, thereby closing the guide strip 6 and preventing the toothbrush handle inside the guide strip 6 from falling off when adjusting or replacing the receiving box 9.

[0053] like Figure 8 , Figure 9 and Figure 10 As shown, the receiving box 9 has a receiving groove provided in the guide plate 701 through several partitions 901. The right end of the receiving box 9 is provided with a discharge port 902 corresponding to the receiving groove. The receiving groove is provided with a discharge component 12, and the inner wall of the discharge port 902 is provided with a limiting component 13.

[0054] Specifically, the receiving trough structure formed by the guide plate 701 and the partition plate 901 facilitates the neat stacking of toothbrush handles during collection, preventing them from being placed haphazardly in the receiving box 9.

[0055] like Figure 8As shown, the discharge assembly 12 includes a push plate 1201. The receiving trough is provided with the push plate 1201. The left end of the push plate 1201 is provided with a connecting rod 1202 that passes through the receiving box 9. The other end of the connecting rod 1202 is provided with a horizontal plate 1203. The horizontal plate 1203 is threadedly connected with a second threaded rod 1204. One end of the second threaded rod 1204 is provided with a bearing 1205 that is fixedly connected to the receiving box 9. The other end of the second threaded rod 1204 is provided with a handle 1206.

[0056] Specifically, when it is necessary to remove the toothbrush handle from the receiving box 9, the rotating handle 1206 drives the second threaded rod 1204 to rotate. The second threaded rod 1204 then drives the horizontal plate 1203, the connecting rod 1202 and the push plate 1201 to move. The push plate 1201 then pushes the toothbrush handle in the receiving trough toward the discharge port 902.

[0057] like Figure 10 As shown, the limiting component 13 includes a groove 1301, a limiting plate 1302, and a second spring 1303. The inner wall of the discharge port 902 is provided with a groove 1301, and the limiting plate 1302 is slidably connected in the groove 1301. The limiting plate 1302 is in the shape of a right trapezoid. A plurality of second springs 1303 are provided in the groove 1301. One end of the second spring 1303 is fixedly connected to the inner wall of the groove 1301, and the other end of the second spring 1303 is fixedly connected to the limiting plate 1302.

[0058] Specifically, when the toothbrush handle comes into contact with the limiting plate 1302, the toothbrush handle continues to move, causing the two limiting plates 1302 to move away from each other. The limiting plate 1302 compresses the second spring 1303, thereby making it easier to remove the toothbrush handle from the collection box 9.

[0059] The working principle of this invention is:

[0060] In use, a receiving box 9 is placed on both the first transport plate 1002 and the support plate 1003. The injection-molded and cut toothbrush handles fall onto the conveyor belt 3 for transport. Guide bars 6 facilitate separation and restrict the movement path of the toothbrush handles. During movement, a fan 5 is activated to cool the toothbrush handles. When the toothbrush handles reach the guide plate 701, the guide plate 701 restricts their fall path, causing them to fall into the receiving trough within the receiving box 9. The receiving trough structure formed by the guide bars 6, guide plate 701, and partition 901 ensures that the toothbrush handles are neatly stacked during collection, preventing them from being randomly placed within the receiving box 9. The utilization rate of the receiving box 9 is increased. When the toothbrush handle falls into the receiving box 9, the weight of the receiving box 9 gradually increases. The receiving box 9 then moves the support plate 1003 and the first switch 1008 downward. The first switch 1008 then contacts and opens the base plate 8. At this time, the third electric telescopic rod 1102 is activated, which moves the baffle 1101 to the right. The baffle 1101 then closes the guide strip 6. At the same time, the second electric telescopic rod 1022 is activated, which moves the second push block 1021 forward. The second push block 1021 pushes the receiving box 9 forward, thereby moving the uncollected material in the receiving box 9 to directly below the guide plate 701. Then, the third electric telescopic rod 1102 is activated again, which moves the baffle 1101 back to its original position. This facilitates the collection box 9 to continue collecting toothbrush handles. When the collection box 9 is full of toothbrush handles, the support plate 1003 is level with the second transport plate 1005, and the support plate 1003 contacts and opens the second switch 1009. At this time, the first electric telescopic rod 1012 is activated, driving the connecting plate 1011 and the first push block 1010 to move to the right. Then, the motor 1015 is activated, driving the first threaded rod 1014 to rotate. The first threaded rod 1014 then drives the support frame 1013, the first electric telescopic rod 1012, the connecting plate 1011, and the first push block 1010 to move forward. The first push block 1010 then pushes the collection box 9, which is full of toothbrush handles, forward onto the second transport plate 1005. The empty receiving box 9 is moved to below the guide plate 701, thereby realizing the automatic replacement and transportation of the receiving box 9, saving manpower, time and effort. When it is necessary to remove the toothbrush handle in the receiving box 9, the rotating handle 1206 drives the second threaded rod 1204 to rotate. The second threaded rod 1204 drives the horizontal plate 1203, the connecting rod 1202 and the push plate 1201 to move. The push plate 1201 pushes the toothbrush handle in the receiving groove toward the discharge port 902. When the toothbrush handle contacts the limiting plate 1302, the toothbrush handle continues to move, causing the two limiting plates 1302 to move away from each other. The limiting plate 1302 compresses the second spring 1303, thereby facilitating the removal of the toothbrush handle from the receiving box 9.
