Description

Technical Field

[0001] The invention relates to the technical field of toothbrush production and transportation, in particular to a toothbrush automatic sorting and unloading device. Background Art

[0002] Toothbrushes are a type of daily cleaning utensil that plays a role in maintaining oral hygiene. In a toothbrush production line, due to the streamlined production, the output of toothbrushes on a production line is relatively large. Therefore, it is necessary to use transportation equipment to automatically load the toothbrushes into the production line.

[0003] Currently, there are devices on the market that automatically feed toothbrushes to the production line. For long products such as toothbrushes, the feeding and sorting method generally uses a lifting structure. However, the efficiency of the lifting structure is relatively slow and it also takes up a large space, resulting in a high cost for the entire equipment. In addition, there are many maintenance points for the mechanism, which is relatively inconvenient. Summary of the invention

[0004] In view of the above-mentioned shortcomings of the prior art, the object of the present invention is to provide an automatic sorting and unloading device for toothbrushes, which adopts a back-and-forth rubbing method to make the toothbrushes flow into the production line in a certain direction.

[0005] A toothbrush automatic sorting and unloading device, comprising a device frame; the unloading device also includes: Feed silo; A material unloading track, which is fixedly mounted on the equipment frame; and The material rubbing mechanism includes a toothbrush fixture, a speed regulating motor located at a position on one side corresponding to a feeding bin, an eccentric wheel, a cam follower, a tension spring fixedly mounted on the eccentric wheel, a rocker for connecting the toothbrush fixture and the tension spring, a rocker fulcrum acting on the rocker, and a guide assembly for providing movement and positioning of the toothbrush fixture; wherein the cam follower is fixedly mounted on the eccentric wheel, and the cam follower and the rocker are in conflict with each other on the side close to each other.

[0006] As a further improvement of the above scheme, the unloading track is composed of four arc-shaped rods, which are arranged in parallel. The two arc-shaped rods at the edge are in contact with the two ends of the toothbrush respectively; the two arc-shaped rods in the middle are located at the corresponding side of the equipment frame, and the distance between the arc-shaped rod and the equipment frame is consistent with the thickness of the toothbrush. In the present invention, the unloading track composed of four arc-shaped rods forms a limited space, so that the toothbrushes sorted by the rubbing mechanism can maintain the order through the unloading track and enter the toothbrush output mechanism.

[0007] As a further improvement of the above scheme, an opening for passing the toothbrush fixture is provided through the bottom of the side wall corresponding to the corresponding feeding track, and the feeding silo is fixedly mounted on the equipment frame, and the feeding end of the feeding track corresponds to the feeding silo opening.

[0008] As a further improvement of the above scheme, a toothbrush receiving groove is provided at the position of the toothbrush fixture facing the equipment frame, at least six toothbrushes are aligned and arranged along the same plane in the toothbrush receiving groove, and the distance between the toothbrush fixture and the equipment frame is consistent with the thickness of the toothbrush. The present invention adopts a design in which the distance between the toothbrush fixture and the equipment frame is consistent with the thickness of the toothbrush, ensuring that the toothbrush fixture always rubs the toothbrushes arranged in a layer back and forth, avoiding jamming and improving the smoothness of rubbing the toothbrushes. In addition, the toothbrush receiving groove adopts a design that imitates the outer contour of the toothbrush. Only when the direction of the toothbrush is completely in line with the toothbrush receiving groove, can the toothbrush pass through the toothbrush receiving groove and enter the feeding track.

[0009] As a further improvement of the above scheme, the speed regulating motor and the equipment frame are fixed, and the eccentric wheel is fixedly installed at the output end of the speed regulating motor, and the eccentric wheel is located below the rocker; the rocker fulcrum has a rectangular block and a convex rod, the rectangular block is fixed to the outer wall of the equipment frame on one side facing the speed regulating motor, and the convex rod is fixedly connected through the center position of the rectangular block.

[0023] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with the embodiments. Additional aspects and advantages of the present invention will be given in part in the following description, and will become apparent from the following description, or will be understood through the practice of the present invention. It should be understood that the following description is only used to explain the present invention and is not intended to limit the present invention.

[0024] The specific embodiments of the present invention are described in detail below. Example 1

[0025] See also Figure 1-4 The present embodiment provides a toothbrush automatic sorting and unloading device, which includes an equipment frame 1, a feeding bin 2 and a unloading track 3 fixedly mounted on the equipment frame 1, and a rubbing mechanism.

[0026] The bottom of the side wall of the feeding bin 2 facing the corresponding unloading track 3 is provided with an opening for passing the toothbrush fixture 4. It should be noted that in order to reduce the difficulty of rubbing the toothbrush back and forth to feed, the toothbrush needs to be placed in the feeding bin 2 in the same posture, that is, multiple toothbrush heads are located on the same side, and the tail ends of the toothbrush handles are also located on the same side. The feeding bin 2 of this embodiment is slightly longer than the toothbrush, so as to improve the neatness of stacking multiple toothbrushes in the bin space.

[0027] The feeding end of the unloading track 3 corresponds to the opening of the feeding bin 2. The unloading track 3 is composed of four arc-shaped rods, which are arranged in parallel. The two arc-shaped rods at the edge are in contact with the two ends of the toothbrush respectively; the two arc-shaped rods in the middle are located at the corresponding side of the equipment frame 1, and the distance between the arc-shaped rod and the equipment frame 1 is consistent with the thickness of the toothbrush. Based on this, the unloading track 3 composed of four arc-shaped rods forms a limited space, so that the toothbrushes sorted by the rubbing mechanism can keep the order through the unloading track 3 and enter the toothbrush output mechanism 13.

[0028] The material rubbing mechanism includes a toothbrush fixture 4, a speed regulating motor 5 located at a position corresponding to one side of the feeding bin 2, an eccentric wheel 6, a cam follower 7, a tension spring 10, a rocker 8 for connecting the toothbrush fixture 4 and the tension spring 10, a rocker fulcrum 9 acting on the rocker 8, and a guide assembly 11 for providing movement and positioning of the toothbrush fixture 4. The cam follower 7 is fixedly mounted on the eccentric wheel 6, and the cam follower 7 and the rocker 8 are in conflict with each other on the side close to each other.

[0029] A toothbrush accommodating groove is provided at the position of the toothbrush fixture 4 facing the equipment frame 1. At least six toothbrushes are aligned and arranged along the same plane in the toothbrush accommodating groove. The distance between the toothbrush fixture 4 and the equipment frame 1 is consistent with the thickness of the toothbrush. Based on this, it is ensured that the toothbrush fixture 4 always rubs the toothbrushes arranged in a layer back and forth to avoid jamming and improve the smoothness of rubbing the toothbrushes. In this embodiment, the toothbrush accommodating groove is designed to imitate the outer contour of the toothbrush. Only when the direction of the toothbrush is completely in line with the toothbrush accommodating groove can the toothbrush pass through the toothbrush accommodating groove and enter the unloading track 3.

[0030] The speed regulating motor 5 is fixed to the equipment frame 1, and the eccentric wheel 6 is fixedly installed at the output end of the speed regulating motor 5, and the eccentric wheel 6 is located below the rocker 8. The rocker fulcrum 9 has a rectangular block and a convex rod. The rectangular block is fixed to the outer wall of the equipment frame 1 on one side facing the speed regulating motor 5, and the convex rod is fixedly connected to the center of the rectangular block. A limiting groove I is provided through the rocker 8, and the convex rod of the rocker fulcrum 9 passes through the rocker 8 through the limiting groove. In this embodiment, the rocker fulcrum 9 is provided to play two roles. On the one hand, the rocker 8 is compressed by means of the rectangular block of the rocker fulcrum 9, thereby preventing the rocker 8 from shaking vertically when moving, thereby ensuring that the cam follower 7 always conflicts with the rocker 8 without separation. On the other hand, when the rocker 8 moves, the convex rod of the rocker fulcrum 9 cooperates with the limiting groove I to realize the movement of the rocker 8 along a fixed trajectory, thereby improving the stability of the operation of the rubbing mechanism. The equipment frame 1 is provided with a limit groove II for providing a moving space for the rocker 8, and the rocker 8 is arranged through the limit groove II through the equipment frame 1. The end of the rocker 8 facing away from the tension spring 10 is connected to the toothbrush fixture 4 through the positioning pin I, and the rocker 8 is slidably sleeved on the positioning pin I. One end of the tension spring 10 is connected to the rocker 8 through the positioning pin II, and the tension spring 10 is slidably sleeved on the positioning pin II, and the other end of the tension spring 10 is fixed to the equipment frame 1. The end of the tension spring 10 connected to the equipment frame 1 is lower than the end connected to the rocker 8. In this embodiment, based on the tension spring 10, the cam follower 7 and the rocker 8 are fitted together. When the speed regulating motor 5 drives the eccentric wheel 6 to rotate, the tension spring 10 outputs a flexible pulling force, so that the rocker 8 drives the toothbrush fixture 4 to move back and forth, thereby achieving the effect of rubbing the toothbrush back and forth.

[0031] Below, the position closest to the feeding bin 2 is marked as point A, and the position closest to the base is marked as point B. At point B, the tension spring 10 is in a stretched state. This embodiment is described by taking the toothbrush fixture 4 making a reciprocating motion between points A and B as an example. The process is as follows: the speed regulating motor 5 continues to drive the eccentric wheel 6 to rotate. At this time, the cam follower 7 shows a tendency to separate from the rocker 8, and the tension spring 10 rebounds due to the reduced resistance to adapt to the aforementioned separation trend. At this time, the rocker 8 drives the toothbrush fixture 4 to move to point A under the action of the rebound force of the tension spring 10. When the tension spring 10 is completely reset, it moves to point A. Then, the speed regulating motor 5 continues to drive the eccentric wheel 6 to rotate, and the resistance force of the cam follower 7 to the rocker 8 continues to increase. At this time, the tension spring 10 is transformed into an extended state again, so that the rocker 8 drives the toothbrush fixture 4 to move to point B.

[0032] The guide assembly 11 is composed of a base and two guide rods. The base is fixedly mounted on the equipment frame 1 and is located above the unloading track 3. The toothbrush fixture 4 is provided with a slide groove adapted to the guide rod, and the toothbrush fixture 4 is slidably sleeved between the two guide rods through the slide groove. The toothbrush fixture 4 is located on the side of the base facing the feeding bin 2. In this embodiment, the toothbrushes are arranged one by one along a certain angle and direction based on the rubbing mechanism, so that the toothbrushes are neatly arranged in a certain order and direction and flow to the production line in sequence.

[0033] In summary, the toothbrush unloading equipment of this embodiment has the following advantages: after the toothbrush is put into the hopper, the toothbrush is rubbed back and forth to make it flow into the production line in a certain direction. The entire unloading structure is simple and easy to maintain, occupies a small area and can be flexibly placed on the production line to improve the toothbrush production efficiency. Example 2

[0034] Please continue reading Figure 5 This embodiment provides a toothbrush automatic sorting and unloading device, which differs from Embodiment 1 in that the unloading device of this embodiment also includes a toothbrush unloading mechanism 13 installed on the device frame 1, and a unloading control mechanism 12 fixedly installed on the device frame 1.

[0035] The toothbrush export mechanism 13 corresponds to the discharge end of the material discharge track 3, and the material discharge control mechanism 12 is located between the toothbrush export mechanism 13 and the material rubbing mechanism. The material discharge control mechanism 12 includes a cylinder and a pressure plate fixedly connected to the output end of the cylinder; the pressure plate is arranged facing the material discharge track 3, and the start-up cycle of the material discharge control mechanism 12 and the toothbrush export mechanism 13 is consistent. The toothbrush export mechanism 13 adopts a manipulator, and the toothbrush it receives is transferred to the production line based on the flipping of the manipulator, which will not be described in detail here.

[0036] In this embodiment, the unloading control mechanism 12 starts to apply pressure to the toothbrushes being transported in a certain order to stop the transportation process. When the pressure plate acts on the toothbrush, the pressure plate is located between the two middle arc rods. At the same time, the toothbrush delivery mechanism 13 starts to transfer the toothbrush under the unloading control mechanism 12 to the production line, thereby optimizing the functional coordination between the toothbrush rubbing sorting, transportation and unloading, thereby meeting the production needs of toothbrushes. It should be noted that the effect of quantitative unloading can be achieved by setting the start cycle of the unloading control mechanism 12, which will not be elaborated here.

[0037] The above embodiments are merely preferred implementations of the present invention. Any simple modification, amendment and substitution of the above embodiments based on the technical essence of the present invention shall fall within the scope of the technical solution of the present invention.
