Description

Technical Field

[0001] The invention belongs to the technical field of injection-molded toothbrush production, and in particular relates to a slitting device for injection-molded toothbrush production. Background Art

[0002] As an important category of daily chemical products, the large-scale production of injection molded toothbrushes relies on efficient and precise slitting processes to separate the conjoined toothbrush blanks after mold forming. However, the existing slitting devices have obvious shortcomings in terms of automation and process connectivity, resulting in rising production costs and fluctuations in yield rates.

[0003] First, during the current slitting process, the operator needs to manually position the injection-molded one-piece toothbrush blanks (usually an array of 6-12 pieces) to the slitting station, and then transfer them to the collection basket batch by batch after slitting is completed.

[0004] Secondly, the plastic flash and debris generated during the slitting process (accounting for about 3%-5% of the total weight of the blank) are usually scattered directly around the equipment and require regular shutdown and cleaning.

[0005] Finally, after the existing slitting equipment is completed, the cut single toothbrush falls randomly into the collection container due to gravity, and the orientation of the brush head and the brush handle is extremely chaotic. More than 90% of the toothbrushes do not meet the requirements. However, the subsequent hair transplantation process strictly requires the orientation of the brush head to accurately match the hair transplantation holes. Summary of the invention

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0023] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0024] Please see attached Figure 1 to Figure 2 As shown, this embodiment provides a slitting device for injection molded toothbrush production, including a conveying assembly 10, the conveying assembly 10 includes a conveying belt 11, a moving frame 13 is slidably connected below the conveying belt 11, a push plate 14 is fixedly connected to the upper end of the moving frame 13, and a collecting cover 15 is fixedly connected to the lower end; A cutting assembly 20, which is assembled on the rear side of the conveyor belt 11, and a storage rack 17 is provided below the cutting assembly 20; The guide assembly 30 includes a guide frame 31, which is mounted on the rear side of the conveyor belt 11. A conveyor belt 1 32 is disposed at the outlet end of the guide frame 31, a conveyor belt 2 33 is disposed at the guide end of the conveyor belt 1 32, and the width of the conveyor belt 2 33 is smaller than that of the conveyor belt 1 32. A return frame 34 is connected to the lower end of the conveyor belt 2 33, and the output end of the return frame 34 is fixedly connected to the upper part of the guide frame 31; When the movable rack 13 moves, the push plate 14 pushes the toothbrush on the conveyor belt 11 into the storage rack 17, and the movable rack 13 will move synchronously to the bottom of the cutting assembly 20. The guide frame 31 is used to send the cut toothbrushes to conveyor belt 1 32 and conveyor belt 2 33. When conveyor belt 2 33 transports toothbrushes, it can screen toothbrushes facing different directions into the reflux frame 34 and send them back to the guide frame 31.

[0025] It should be noted that the inner cavity of the guide frame 31 is an inclined bottom plate, the inclination is preferably greater than 10°, and the bottom end of the inclination is located at the outlet of the guide cover 31, the conveyor belt 1 32 is a crawler belt installed upwardly inclined, and the outer surfaces of the conveyor belt 11, the conveyor belt 1 32 and the conveyor belt 2 33 are all provided with convex strips for transporting toothbrushes; Here, the conveyor belt 11, the conveyor belt 1 32 and the conveyor belt 2 33 are all externally provided with a driving module and a control module for controlling the speed and start and stop of the operation thereof. Preferably, in order to ensure the unloading effect of the air guide cover 31 and the return flow frame 34, a vibration motor can be installed below the air guide cover 31 and the return flow frame 34, so that the air guide cover 31 and the return flow frame 35 can be vibrated by the vibration motor, thereby improving the efficiency of the downward sliding discharge of the toothbrush; An infrared sensor is installed on the outer wall of the conveyor belt 11 at the side of the push plate 14, so that when the push plate 14 moves, the infrared sensor will detect the movement of the push plate 14, and then control the conveyor belt 11 to stop running. After the push plate 14 is reset, the conveyor belt 11 is controlled to move again to realize automatic control of the conveyor belt 11; The width of conveyor belt 2 33 is smaller than that of conveyor belt 1 32, and its width is preferably 40% to 45% of that of conveyor belt 1 32, and conveyor belt 2 33 is inclined, and its side close to the center of conveyor belt 1 32 is inclined upward, and the inclination angle is preferably 3° to 5°, so that when the toothbrushes on conveyor belt 2 33 are transported, the toothbrushes on conveyor belt 2 33 with greater gravity at their end can rely on the inclination angle to fit above conveyor belt 2 33, while the toothbrushes on the outside of conveyor belt 2 33 with greater gravity at their end will fall downward due to gravity, thereby achieving screening.

[0026] In this embodiment, when in use, the conveyor belt 11 transports the injection molded toothbrush toward the push plate 14, and then the moving frame 13 drives the push plate 14 and the collection cover 15 to move, and the push plate 14 pushes the toothbrush to the bottom of the cutting assembly 20, and the collection cover 15 moves to the bottom of the cutting assembly 20 to collect waste, and then the cutting assembly 20 cuts and polishes the toothbrush. After the cutting is completed, the collection cover 15 is retracted, so that the toothbrush falls downward into the guide frame 31, and then the conveyor belt 1 32 conveys the toothbrush upward to the conveyor belt 2 33. At this time, the toothbrush with the center of gravity facing the outside of the conveyor belt 2 33 will fall into the return frame 34 due to gravity and flow back to the guide frame 31 for transportation again.

[0027] Next, please refer to Figures 2 to 4 An additional chassis is provided below the conveyor belt 11, and the guide frame 31, conveyor belt 1 32, conveyor belt 2 33 and return frame 34 are all installed on the additional chassis. The conveying assembly 10 also includes a pneumatic rod 12, which is fixedly installed below the conveyor belt 11, and the output end of the pneumatic rod 12 is fixedly connected to the movable frame 13. A collecting box 16 is fixedly installed on the additional chassis below the conveyor belt 11, and an inlet is opened at the upper end of the collecting box 16, and the discharge outlet at the lower end of the collecting cover 15 is movably sleeved in the inlet at the upper end of the collecting box 16.

[0028] The lower end of the conveyor belt 11 is fixedly connected with two sets of limiting long rods, and both ends of the collecting cover 15 are slidably connected to the outer rings of the limiting long rods, and the collecting cover 15 is a triangular hollow cover, the side with the largest surface area is close to the conveyor belt 11 and is provided with a material receiving port, and the lower end of the inclined part of the bottom surface is provided with a discharge port, and a pipe is fixedly installed at the lower end at the position of the discharge port, and the pipe is movably sleeved in the inlet at the upper end of the collecting box 16; Preferably, the width of the upper entrance of the collecting box 16 is greater than the width of the conveyor belt 11, so that when the push plate 14 pushes the toothbrush out of the conveyor belt 11, the collecting cover 15 will also move synchronously to the bottom of the cutting assembly 20 to receive the waste generated during slitting; The collecting box 16 is hinged with a box door to facilitate the subsequent recycling of waste materials.

[0029] In this embodiment, when the toothbrush is transported to the position of the push plate 14 by the conveyor belt 11, the pneumatic rod 12 drives the moving frame 13 and the push plate 14 to move, pushing the toothbrush backwards, and the moving frame 13 also drives the collection cover 15 to the bottom of the toothbrush, so that the waste generated when the toothbrush is cut can fall into the collection cover 15 and flow into the collection box 16 for collection. After the cutting is completed, the pneumatic rod 12 is reset, and drives the push plate 14 to reset and wait for the second push, and the collection cover 15 is also reset to avoid affecting the discharge of the toothbrush.

[0030] Next, please refer to Figure 5 to Figure 6Two groups of storage racks 17 are fixedly connected to one side of the conveyor belt 11 close to the cutting assembly 20, and the two groups of storage racks 17 are installed symmetrically with each other. Pneumatic rods 18 are fixedly installed at the lower ends of the two groups of storage racks 17, and clamping racks 19 are fixedly connected to the output ends of the pneumatic rods 18. The clamping racks 19 are slidably connected to the lower ends of the storage racks 17.

[0031] It should be noted that the clamping frame 19 is composed of two groups of cylindrical tubes and two groups of long plates, wherein the cylindrical tubes are slidably connected in the storage frame 17, the long plate at the lower end is connected to the pneumatic rod 18, and the upper end of the long plate at the upper end is fixedly connected with an anti-skid pad, and the inner cavity of the storage frame 17 and the side opposite to the upper end of the long plate are also fixedly connected with an anti-skid pad. Here, the material of the anti-skid pad is preferably rubber material, in order to use the two groups of anti-skid pads to clamp the cut toothbrush to prevent the toothbrush from slipping and displacement during the cutting process, which affects the cutting effect; The height of the lower end of the inner cavity of the storage rack 17 is lower than the height of the upper end of the conveyor belt 11, and when the clamping rack 19 is completely lowered and fits on the lower end of the inner cavity of the storage rack 17, the height of the upper end of the clamping rack 19 is flush with the height of the upper end of the conveyor belt 11, so that the push plate 14 can push the toothbrush directly to the upper end of the clamping rack 19, which is convenient for subsequent clamping; The collecting cover 15 cannot contact the pneumatic rod 18, so that the pneumatic rod 18 does not affect the movement of the collecting cover 15; The storage rack 17 is fixedly connected to the rear side of the conveyor belt 11 through a triangular bracket, and a plurality of groups of hole grooves (not shown in the figure) are reserved on the rear side of the conveyor belt 11, so that the distance between the two groups of storage racks 17 can be controlled by adjusting the installation position of the storage rack 17, so as to cope with toothbrushes of different lengths.

[0032] In this embodiment, after the push plate 14 pushes the injection molded toothbrush into the storage rack 17, the pneumatic rod 18 operates to push the clamping rack 19 upward, clamping the toothbrush between the clamping rack 19 and the upper end of the inner cavity of the storage rack 17, thereby stably clamping the toothbrush. After the toothbrush is cut, the clamping of the toothbrush is released, allowing the toothbrush to fall freely.

[0033] Next, please refer to Figure 6 to Figure 7The cutting assembly 20 includes an electric guide rail 21, which is installed on the rear side of the conveyor belt 11 through an assembly bracket (and the electric guide rail 21 is a common X-axis electric drive guide rail in the prior art, which will not be described in detail here), an electric push rod 22 is installed at the lower end of the electric guide rail 21, and a placement rack 23 is fixedly installed at the lower end of the electric push rod 22. The inner cavity of the placement rack 23 is slidably connected with two groups of tool holders 24, and the inner cavities of the two groups of tool holders 24 are rotatably connected with blades 25 through ball bearings. A motor 26 is fixedly installed on the outer side of the placement rack 23, and the output shaft of the motor 26 passes through the placement rack 23 and is fixedly connected to a drive shaft 27. The outer ring of the drive shaft 27 passes through the two groups of tool holders 24 and is slidably connected at the center of the two groups of blades 25. The upper ends of the two groups of tool holders 24 are slidably connected with positioning bolts 28, and the positioning bolts 28 are threadedly connected to the upper end of the placement rack 23.

[0034] A plurality of positioning slots are provided above the placement rack 23, and positioning bolts 28 are slidably connected in the slots, so as to use the positioning bolts 28 to fix the tool holder 24 at different positions, and to facilitate adjustment of the distance between the two sets of tool holders 24 to cope with toothbrushes of different widths.

[0035] The outer edge of the blade 25 is a cutting edge, and the inner ring parts of the two sets of blades 25 that are away from each other are fixedly connected with grinding sandpaper, so that during the slitting process, the grinding sandpaper on the inner ring of the blade 25 can be used to grind the toothbrush after slitting to avoid burrs on the surface of the toothbrush after slitting, which affects the product quality.

[0036] It should be noted that the inner cavity of the placement rack 23 is provided with a limit guide rod, and the two sets of tool holders 24 are slidably connected to the outer ring of the limit guide rod, thereby limiting the range of movement of the tool holders 24 and improving stability; The center of the two sets of blades 25 are provided with a hexagonal through slot, and the drive shaft 27 is a hexagonal long rod, which is designed to use the drive shaft 27 to drive the blades 25 to rotate and enable the blades 25 to slide on the outer ring of the drive shaft 27; The side of the placement rack 23 can be disassembled to facilitate the subsequent operation of replacing the blade; Preferably, the height of the lower end of the outer edge of the blade 25 is higher than the height of the lower end of the placement rack 23 to prevent the placement rack 23 from affecting the movement of the blade 25 during slitting.

[0037] In this embodiment, after the injection molded toothbrush is clamped and fixed by the clamping frame 19, the electric push rod 22 pushes the placement frame 23 down so that the blade 25 is at the same height as the toothbrush. At this time, the motor 26 runs, driving the drive shaft 27 and the blade 25 to rotate, and then the electric guide rail 21 runs, driving the blade 25 to move toward the position of the toothbrush. The toothbrush is cut and polished by the rotating blade 25, and then the blade 25 is reset, and the cut toothbrush is polished again to achieve rapid cutting of the toothbrush.

[0038] Please refer again Figures 9 and 10 The guide assembly 30 also includes a screw rod 36, which is threadedly connected to the middle part of the inner cavity of the guide frame 31. The lower end of the screw rod 36 is rotatably connected to a blocking rod 37 through a ball bearing. The blocking rod 37 is movably sleeved in the inner cavity at the outlet of the guide frame 31 and is located above the conveyor belt 32.

[0039] A mounting plate is fixedly connected to the middle of the outlet position at the lower end of the guide frame 31, and the screw rod 36 is threadedly connected to the mounting plate. Limit rods are fixedly connected to both sides of the upper end of the blocking rod 37, and the two sets of limit rods are slidably connected to the mounting plate of the inner cavity of the guide frame 31.

[0040] It should be noted that a handle is fixedly connected to the upper end of the screw rod 36, so as to control the height of the blocking rod 37 by rotating the screw rod 36, and thus control the height of the toothbrush that the conveyor belt 1 32 can pass through; Here, the blocking rod 37 is located at the upper end of the conveyor belt 1 32, and the gap between the convex strips on the top surface of the conveyor belt 1 32 allows only one toothbrush to lie inside, while the toothbrush facing vertically will be located above the convex strips. At this time, when the toothbrush is transported in the conveyor belt 1 32, the toothbrush lying in the gap between the convex strips will pass through the blocking rod 37 smoothly, while the toothbrush lying vertically above the convex strips will not be able to pass due to the obstruction of the blocking rod 37; Preferably, in order to ensure that the toothbrushes can still be stored in the gaps between the convex strips in the conveyor belt 33 when they are transported to the conveyor belt 33, a screw rod 36 and a blocking rod 37 compatible with the conveyor belt 33 can be installed on the conveyor belt 33, so that the toothbrushes will be blocked by the blocking rod 37 compatible with the conveyor belt 33 during transportation, so that only the toothbrushes stored in the gaps between the convex strips can pass through the blocking rod 37, and the toothbrushes located on the convex strips will fall into the gaps between the convex strips through limiting and pushing, thereby preventing the toothbrushes from being located above the convex strips during screening and causing tilting, thereby affecting the accuracy of screening.

[0041] In this embodiment, when the toothbrush falls into the guide frame 31 and is transported by the conveyor belt 32, the screw rod 36 is driven to rotate, pushing the blocking rod 37 to descend, so that the distance between the lower end of the blocking rod 37 and the convex strip on the surface of the conveyor belt 32 is smaller than the height of the toothbrush. At this time, the toothbrush lying in the gap between the convex strips of the conveyor belt 32 can pass smoothly under the blocking rod 37, while the vertical toothbrush lying on the convex strip will be blocked by the blocking rod 37 and cannot pass through, thereby screening the toothbrushes in the vertical and horizontal directions.

[0042] Please refer again Figures 11 to 13The guide assembly 30 also includes a pneumatic rod three 38, which is fixedly installed in the middle of the outer side of the conveyor belt two 33, and the output end of the pneumatic rod three 38 passes through the outer side of the conveyor belt two 33 and is placed above the conveying part of the conveyor belt two 33. A guide plate 39 is fixedly connected to the output end of the pneumatic rod three 38, and two sets of limit rods are fixedly connected to one end of the guide plate 39 close to the pneumatic rod three 38, and the limit rods are slidably connected to the conveyor belt two 33.

[0043] A discharge belt 35 is provided at the guide end of the conveyor belt 2 33, and the discharge belt 35 is used to receive the screened toothbrushes and transport the screened toothbrushes to the subsequent processing links. At the same time, the conveyor belt 1 32 is also provided with a matching guide plate 39 and a pneumatic rod 38 (such as Figure 8 As shown), when necessary, the guide plate 39 mounted on the conveyor belt 1 32 can be driven to move, pushing the toothbrush close to the conveyor belt 2 33, so that toothbrushes of different lengths and types can be pushed and limited by the guide plate 39 mounted on the conveyor belt 1 32 when being transported in the conveyor belt 1 32, so that they are always close to the direction of the conveyor belt 2 33, which is convenient for subsequent screening; The entrance and exit of the conveyor belt 2 33 are both provided with triangular baffles (such as Figure 8 As shown), the triangular baffle is not fixedly connected to the rolling crawler part, so that when the toothbrush is separated from the conveyor belt 1 32, the toothbrush can be stably placed in the conveyor belt 2 33 by relying on the limiting position of the baffle, and when the toothbrush is transported out of the conveyor belt 2 33, the baffle can also be relied on to stably place the toothbrush on the discharge belt 35; The pneumatic rod 1 12, the pneumatic rod 2 18 and the pneumatic rod 3 38 in this embodiment are all connected to a control module and an air pump (not shown in the figure, and this is a common technical structure in the prior art, but no further description is given), which is used to control the extension and retraction process; The guide plate 39 is provided with a slope at one end close to the conveyor belt 1 32, and the slope is placed above the end of the conveyor belt 1 32; Here, when the toothbrush located in the conveyor belt 1 32 is being transported upward, the guide plate 39 will use the slope at its end to control the displacement of the toothbrush during transportation, so that when the toothbrush is transported to the conveyor belt 2 33, it will fit on the guide plate 39, and the guide plate 39 can be driven by the pneumatic rod 38 to move at the upper end of the conveyor belt 2 33, so that the conveyor belt 2 33 can screen toothbrushes of different models and sizes, and avoid toothbrushes that are too short (such as children's toothbrushes) from remaining in the conveyor belt 2 33 no matter which side the heavier end faces, and when the shorter toothbrushes are transported to the top of the conveyor belt 2 33, they will also fit on the guide plate 39 due to the guidance of the slope of the guide plate 39, so as to avoid the guide plate 39 blocking the conveyor belt 2 33 after displacement, resulting in the toothbrushes transported by the conveyor belt 1 32 being blocked, affecting the transportation.

[0044] In this embodiment, after the toothbrushes are transported to the conveyor belt 2 33 via the conveyor belt 1 32, due to the short width of the conveyor belt 2 33, the toothbrushes with their centers of gravity facing the outside of the conveyor belt 2 33 will fall downward due to gravity and leave the conveyor belt 2 33, while the toothbrushes with their centers of gravity facing the inside of the conveyor belt 2 33 will stay on the conveyor belt 2 33 for transportation due to their centers of gravity being biased inside the conveyor belt 2 33, and the toothbrushes screened by the conveyor belt 2 33 will be discharged through the discharge belt 35. When screening toothbrushes of shorter length, the pneumatic rod 38 will push the guide plate 39 to move to shorten the transport area on the conveyor belt 2 33, so as to avoid the toothbrushes being too short, so that no matter which side the centers of gravity are facing, they can be transported by the conveyor belt 2 33, which affects the screening effect.

[0045] The working principle of the present invention is as follows: when in use, the conveyor belt 11 transports the injection molded toothbrush toward the push plate 14, and then the pneumatic rod 12 drives the moving frame 13 and the push plate 14 to move, pushing the toothbrush into the storage rack 17. At this time, the pneumatic rod 2 18 operates to push the clamping frame 19 to rise, clamping the toothbrush at the upper end of the inner cavity of the clamping frame 19 and the storage rack 17, and stably clamping the toothbrush. At the same time, the moving frame 13 will also drive the collecting cover 15 to the bottom of the toothbrush, so that the waste generated when the toothbrush is cut can fall into the collecting cover 15 and flow into the collecting box 16 for collection. At this time, the electric push rod 22 pushes the placement frame 23 down, so that the blade 25 is at the same height as the toothbrush, and then the motor 26 drives the drive shaft 27 and the blade 25 to rotate, and through the operation of the electric guide rail 21, drives the blade 25 to move to the position of the toothbrush for cutting and grinding, and then the blade 25 is reset, and the cut toothbrush is grinded for the second time, so as to achieve rapid cutting of the toothbrush. The processed toothbrush is released from the clamping state and falls into the guide frame 31, and is transported through the conveyor belt 1 32. At this time, the screw rod 36 is driven to rotate, pushing the blocking rod 37 down, so that the distance between the lower end of the blocking rod 37 and the convex strips on the surface of the conveyor belt 1 32 is smaller than the height of the toothbrush, so that the toothbrush lying in the gap between the convex strips of the conveyor belt 1 32 can pass smoothly under the blocking rod 37, while the vertical toothbrush lying on the convex strips will be blocked by the blocking rod 37 and cannot pass. After the toothbrush is transported to the conveyor belt 2 33, due to the short width of the conveyor belt 2 33, the toothbrush with the center of gravity facing the outside of the conveyor belt 2 33 will fall downward due to gravity and leave the conveyor belt 2 33. The toothbrush with the center of gravity facing the inside of the conveyor belt 2 33 will stay on the conveyor belt 2 33 for transportation because the center of gravity is biased inside the conveyor belt 2 33, and the toothbrush screened by the conveyor belt 2 33 will be discharged through the discharge belt 35.

[0046] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
