Description

Technical Field

[0001] This application relates to the field of toothbrush production equipment technology, specifically to a toothbrush lifting machine. Background Technology

[0002] In existing technologies, toothbrush manufacturing typically involves injection molding of the toothbrush handle, material sorting and polishing, bristle implantation, and final cleaning and packaging. Bristle implantation is generally performed on an automatic bristle implantation machine. During this process, the toothbrush handle must be placed face up into the machine's fixture. To achieve automatic feeding and orientation of the toothbrush handles, a lifting mechanism is typically used to sequentially lift several handles upwards, orienting them during the lifting process.

[0003] Chinese patent document CN214340771U discloses a fully automatic two-section feeding and sorting toothbrush handle machine, specifically disclosing a conveyor belt. A loading platform is fixedly mounted at the end of the conveyor belt, and the loading platform is inclined. Multiple sets of stacked loading lifting groups are located at the bottom of the inclined surface of the loading platform, each including a lifting plate. This utility model relates to a handle sorting machine, and more particularly to a fully automatic two-section feeding and sorting toothbrush handle machine, belonging to the field of toothbrush manufacturing and processing technology. In this utility model, the lifting plate lifts and moves individual toothbrush handles to the upper part of the lifting plate at a higher position. By using a single set of lifting plates to feed the toothbrush handles individually, the problem of having too many toothbrush handles and the inconvenience of sorting and feeding them is solved.

[0004] However, in the aforementioned patent, the thickness of the lifting plates is uniform, which means that the lowermost lifting plate can only lift one toothbrush handle at a time. This places high demands on the initial placement of the toothbrush handles; otherwise, the lowermost lifting plate may need to lift and lower multiple times before it can lift and transport a toothbrush handle upwards, resulting in poor overall lifting efficiency. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this application provides a toothbrush lifting device.

[0006] This application adopts the following technical solution: a toothbrush lifting machine, including a pair of upright plates and a plurality of fixed plates disposed between the pair of upright plates, a movable top plate is provided between two adjacent fixed plates, the plurality of fixed plates are arranged in a stepped manner, the distance between two adjacent fixed plates gradually decreases from bottom to top, one side of the movable top plate is attached to the side wall of a fixed plate on the lower side, and the other side of the movable top plate is attached to the side wall of a fixed plate on the higher side;

[0007] A connecting plate is provided below the pair of upright plates, and the bottom of several movable top plates is located on the top of the connecting plate. A hydraulic cylinder is provided at the bottom of the connecting plate, and the hydraulic cylinder is used to drive the connecting plate and the movable top plates to reciprocate along the length direction of the fixed plate.

[0008] Optionally, the thickness of some of the movable top plates gradually decreases from bottom to top.

[0009] Optionally, the bottom of the connecting plate is provided with a wedge-shaped block, the inclined surface of the wedge-shaped block is connected to the connecting plate, and the flat surface of the wedge-shaped block is connected to the push rod of the hydraulic cylinder through a universal joint.

[0010] Optionally, the tilt angle of the connecting plate is the same as the tilt angle of the movable top plate, and the fixed plate is connected to the upright plate by bolts.

[0011] Optionally, when the push rod of the hydraulic cylinder is in the retracted state, the top height of the movable top plate is lower than the top height of the two adjacent fixed plates, and a toothbrush handle placement area is formed between the top of the movable top plate and the top of the two adjacent fixed plates.

[0012] When the push rod of the hydraulic cylinder is in the extended state, the top height of the movable top plate is lower than the top height of the two adjacent fixed plates, and the toothbrush handle moves from the placement area on the lower side to the placement area on the higher side.

[0013] Optionally, the movable top plate has a cavity, the top of the cavity extending upward through the top of the movable top plate, a support plate and an adjusting block adaptedly disposed within the cavity, the adjusting block being disposed on the top of the support plate, the outer wall of the adjusting block being fitted against the inner wall of the cavity, and the adjusting block comprising a plurality of mutually fitted adjusting plates.

[0014] The support plate is provided with an adjusting screw, which is connected to the support plate by a thread. The adjusting screw is used to adjust the length of the adjusting plate protruding to the outside of the cavity.

[0015] Optionally, each of the adjusting plates has a limiting hole at its bottom, and the support plate has a plurality of threaded holes. The plurality of limiting holes and the plurality of threaded holes correspond one-to-one and are coaxial. One end of the adjusting screw has a wrench insertion hole, and the other end of the adjusting screw passes through the threaded hole and extends into the limiting hole.

[0016] Compared with the prior art, this application adjusts the distance between two adjacent fixing plates to achieve a gradual decrease in the volume of several placement areas from bottom to top. This allows the lowest placement area to lift multiple toothbrush handles at once, and the multiple toothbrush handles are screened during the continuous lifting process, avoiding the placement area being in an empty state and improving the lifting efficiency of the toothbrush handles.

[0021] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] like Figure 1-3 As shown, a toothbrush lifting device includes a pair of upright plates 1 and a plurality of fixed plates 2 disposed between the pair of upright plates 1. A movable top plate 3 is provided between two adjacent fixed plates 2. The device is characterized in that the plurality of fixed plates 2 are arranged in a stepped manner, and the distance between two adjacent fixed plates 2 gradually decreases from bottom to top. One side of the movable top plate 3 is attached to the side wall of a fixed plate 2 on the lower side, and the other side of the movable top plate 3 is attached to the side wall of a fixed plate 2 on the higher side. A connecting plate 4 is provided below the pair of upright plates 1, and the bottom of the plurality of movable top plates 3 is located at the top of the connecting plate 4. A hydraulic cylinder 5 is provided at the bottom of the connecting plate 4, and the hydraulic cylinder 5 is used to drive the connecting plate 4 and the movable top plate 3 to reciprocate along the length direction of the fixed plates 2.

[0023] The fixed plates 2 have a uniform thickness, but the distance between adjacent fixed plates 2 is inconsistent, which causes the thickness of the movable top plates 3 to gradually decrease from bottom to top. Furthermore, when the push rod of the hydraulic cylinder 5 is in the retracted state, the top height of the movable top plate 3 is lower than the top height of the two adjacent fixed plates 2, and a toothbrush handle placement area 6 is formed between the top of the movable top plate 3 and the top of the two adjacent fixed plates 2. When the push rod of the hydraulic cylinder 5 is in the extended state, the top height of the movable top plate 3 is lower than the top height of the two adjacent fixed plates 2, and the toothbrush handle moves from the lower placement area 6 to the higher placement area 6. Thus, the volume of the lowermost placement area 6 is greater than the volume of the uppermost placement area 6, causing the number of toothbrushes that can be stored in the placement areas 6 to gradually decrease until only one remains. This achieves rapid lifting of the toothbrush handle and, during the lifting process, the toothbrush handle is screened, effectively improving the lifting efficiency and ensuring a sufficient supply of toothbrush handles to the bristle implantation machine.

[0024] The bottom of the connecting plate 4 is provided with a wedge block 40. The inclined surface of the wedge block 40 is connected to the connecting plate 4. The flat surface of the wedge block 40 is connected to the push rod of the hydraulic cylinder 5 through a universal joint 50. The cooperation between the wedge block 40 and the universal joint 50 ensures that the extension and retraction of the hydraulic cylinder 5 can reliably drive the connecting plate 4 to move up and down, thereby realizing the movement of the movable top plate 3 between the fixed plates 2.

[0025] The tilt angle of the connecting plate 4 is the same as that of the movable top plate 3, and the fixed plate 2 is connected to the upright plate 1 by bolts. The fixed plate 2 is in a detachable connection state, which allows for easy adjustment of the spacing between two adjacent fixed plates 2.

[0026] The movable top plate 3 has a cavity 31 inside, and the top of the cavity 31 extends upward through the top of the movable top plate 3. A support plate 32 and an adjusting block are adaptedly provided inside the cavity 31. The adjusting block is located on the top of the support plate 32, and the outer wall of the adjusting block is in contact with the inner wall of the cavity 31. The adjusting block includes several mutually in contact adjusting plates 33. An adjusting screw 34 is provided on the support plate 32. The adjusting screw 34 is connected to the support plate 32 by a thread. The adjusting screw 34 is used to adjust the length of the adjusting plate 33 protruding to the outside of the cavity 31. Rotating the adjusting screw 34, under the action of the threaded connection, the adjusting screw 34 will rotate towards the inside or outside of the cavity 31, thus realizing the ejection or retraction of the adjusting plate 33. This allows the tops of several adjusting plates 33 to be at different heights, thereby reliably changing the top shape of the adjusting block, which in turn changes the shape of the placement area 6. This ensures that the toothbrush handle can be placed oriented within the placement area 6, improving the stability of the toothbrush handle moving from the lower side of the placement area 6 to the higher side.

[0027] Each adjusting plate 33 has a limiting hole 330 at its bottom. The support plate 32 has several threaded holes 320, with each limiting hole 330 corresponding to and coaxial with the threaded holes 320. One end of the adjusting screw 34 has a wrench insertion hole 340, and the other end of the adjusting screw 34 passes through the threaded hole 320 and extends into the limiting hole 330. A wrench can be inserted into the wrench insertion hole 340, allowing adjustment of the screwing depth of the adjusting screw 34. Furthermore, the adjusting screw 34 is threadedly connected to the threaded hole 320, but there is no direct connection between the adjusting screw 34 and the limiting hole 330. This ensures that the rotation of the adjusting screw 34 causes the adjusting plate 33 to reciprocate vertically.

[0028] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
