Description

A feeding mechanism for a glass slide thermal transfer printer Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a feeding mechanism for a glass slide thermal transfer printer. Background Technology

[0002] Glass slides, as a professional sampling carrier widely used in hospitals, primarily function to hold and transfer lesion samples to be tested. During medical testing, to ensure the accuracy and traceability of results, detailed patient information is precisely printed on one end of the slide using a thermal transfer printer.

[0003] Traditional methods of loading glass slides often involve manual loading, which is inefficient and cannot meet the needs of large-scale production or processing of large numbers of experimental samples. Secondly, manual loading makes it difficult to ensure that the position and angle of the glass slide are completely consistent each time, which can cause the glass slide to shift during the printing process, affecting printing accuracy and leading to problems such as misalignment and deformation of the printed pattern, thus reducing print quality. Summary of the Invention

[0004] The purpose of this invention is to provide a feeding mechanism for a glass slide thermal transfer printer, so as to solve the problem of low efficiency of manual feeding mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for a glass slide thermal transfer printer, comprising a feeding bin, in which multiple glass slides to be printed are stacked; side plates are movably connected to both sides of the feeding bin; a support plate is fixed to the bottom of the side plates; and a base box is fixedly connected to the bottom of the support plate via a fixing block; further comprising: a pushing block disposed directly below the feeding bin; an inclined surface provided on the upper side of the pushing block; a connecting block fixed to the bottom of the pushing block; the connecting block being slidably connected to the support plate; and a pushing drive component installed at the bottom of the connecting block; and a feeding component disposed above the support plate; a first slider fixed to the bottom of the feeding component; a first guide rail slidably connected to the bottom of the first slider; and a feeding drive component installed on one side of the first slider.

[0006] Preferably, the pusher block is made of plastic, and there are two sets of pusher blocks, which are symmetrically distributed.

[0007] Preferably, the feeding component includes a rectangular piece with ramps on both sides and a brim at one end. The brim is inclined downwards. The top surface of the rectangular piece is parallel to the top surface of the support plate. The bottom of the rectangular piece is fixedly connected to the first slider by a fixing block.

[0008] Preferably, the pusher drive includes a drive gear and a drive motor. A rack meshes with one side of the drive gear. The output end of the drive motor is fixedly connected to the drive gear. The drive motor is installed inside the base box. A connecting plate is fixedly connected to the top of the rack through a fixing block. Both ends of the connecting plate are fixedly connected to the pusher block through the connecting block.

[0009] Preferably, two second sliders are symmetrically fixed to the bottom of the connecting plate, and the bottom of the second sliders is slidably connected to a second guide rail, the bottom of the second guide rail being fixed to the base box.

[0010] Preferably, a material support plate is fixed at the bottom of the feeding hopper, with one side of the material support plate closed and the other side open.

[0011] Preferably, the feeding drive includes synchronous pulleys, two of which are mounted on the base box, and a toothed belt is drivingly connected between the two synchronous pulleys, the toothed belt being fixedly connected to the first slider.

[0012] Preferably, an L-shaped block is provided on one side of the rack, a sponge block is fixed to the outside of the L-shaped block, the sponge block is impregnated with grease, the bottom of the L-shaped block is fixed to the base box, and the teeth of the rack are in contact with the sponge block.

[0013] Preferably, the top of the support plate is provided with a horizontal groove, and the fixing block at the bottom of the rectangular piece slides automatically within the horizontal groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses a pusher drive to move a pusher block, which automatically pushes the glass slide at the bottom of the feeding bin onto the feeding component. The feeding drive then automatically moves the feeding component, which in turn pushes the glass slide below the heat transfer machine for printing. This facilitates the automatic feeding of glass slides one by one, solving the problems of low efficiency and difficulty in ensuring that the position and angle of the glass slides are completely consistent each time.

[0017] 2. The pusher block in this utility model has an inclined surface. The inclined surface can push the upper glass slide upward, thereby reducing the pressure on the second to last glass slide on the lower side, so that it will not be broken due to the pressure of multiple glass slides. This allows for better separation of the two bottom glass slides during the pusher process. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: Please refer to Figures 1-4. The figure shows a feeding mechanism for a glass slide thermal transfer printer, including a feeding bin 1. Multiple glass slides to be printed are stacked in the feeding bin 1. Side plates 2 are movably connected to both sides of the feeding bin 1. A support plate 3 is fixed to the bottom of the side plates 2. A base box 4 is fixedly connected to the bottom of the support plate 3 through a fixing block.

[0028] It also includes: a pusher block 5 located directly below the feeding bin 1, the upper side of the pusher block 5 having an inclined surface 6, the bottom of the pusher block 5 having a connecting block 7 fixed thereon, the connecting block 7 being slidably connected to the support plate 3, and the bottom of the connecting block 7 having a pusher drive component 8 installed thereon. The inclined surface 6 on the pusher block 5 can push the upper glass slide upwards, thereby reducing the pressure on the second to last glass slide on the lower side, preventing it from being crushed by the pressure of multiple glass slides, and thus allowing the two bottom glass slides to be better separated during the pusher process.

[0029] A feeding component 9 is disposed above the support plate 3. A first slider 10 is fixed at the bottom of the feeding component 9. A first guide rail 11 is slidably connected to the bottom of the first slider 10. A feeding drive component 12 is installed on one side of the first slider 10.

[0030] In this solution, the pusher 8 drives the pusher block 5 to move, thereby automatically pushing the glass slide at the bottom of the feeding bin 1 onto the feeding component 9. Then, the feeding drive 12 automatically moves the feeding component 9, and the feeding component 9 pushes the glass slide below the heat transfer machine for printing, thus facilitating the automatic feeding operation of the glass slides one by one.

[0031] Furthermore, referring to Figure 2, the pusher block 5 is made of plastic material. There are two sets of pusher blocks 5, and the two sets of pusher blocks 5 are symmetrically distributed. The pusher blocks are arranged in a left-right split manner, which makes the pressure on the glass slide from the upper glass slide more uniform and prevents skewing.

[0032] Furthermore, referring to Figure 5, the feeding component 9 includes a rectangular piece 13, with ramps 14 on both sides of the rectangular piece 13, a brim 15 at one end of the rectangular piece 13, the brim 15 being inclined downwards, the top surface of the rectangular piece 13 being parallel to the top surface of the support plate 3, and the bottom of the rectangular piece 13 being fixedly connected to the first slider 10 via a fixing block.

[0033] Specifically, when the rectangular piece 13 moves and drives the glass slide to move, the brim 15, which is inclined downward at one end of the rectangular piece 13, reduces the contact area with one end of the glass slide, preventing the glass slide from tilting up during the pushing process. This gives the glass slide a positioning effect during feeding, and the rectangular piece 13 will not detach when it retracts.

[0034] Further, please refer to Figure 7. The pusher drive component 8 includes a drive gear 16 and a drive motor 17. A rack 18 meshes with one side of the drive gear 16. The output end of the drive motor 17 is fixedly connected to the drive gear 16. The drive motor 17 is installed inside the bottom box 4. A connecting plate 19 is fixedly connected to the top of the rack 18 through a fixing block. Both ends of the connecting plate 19 are fixedly connected to the pusher block 5 through the connecting block 7.

[0035] As shown in Figure 7, the bottom of the connecting plate 19 has two second sliders 20 symmetrically fixed. The bottom of the second sliders 20 is slidably connected to a second guide rail 21. The bottom of the second guide rail 21 is fixed to the base box 4. The second sliders 20 and the second guide rail 21 enable the connecting plate 19 to move with higher precision.

[0036] Specifically, during the feeding process, the drive motor 17 drives the drive gear 16 to rotate, the drive gear 16 drives the rack 18 to move, the rack 18 drives the connecting plate 19 to move, and the connecting plate 19 drives the pusher block 5 to move, thereby pushing the glass slide at the bottom of the feeding bin 1 onto the rectangular sheet 13 for automatic feeding.

[0037] Furthermore, referring to Figure 6, a support plate 22 is fixed at the bottom of the feeding bin 1. One side of the support plate 22 is closed, while the other side is not closed. The glass slide at the bottom of the feeding bin 1 will fall onto the support plate 22. When the pusher block 5 returns to its initial position, the high point of the inclined surface 6 will come into contact with and separate from the next glass slide, which will generate a supporting force on the glass slide at that point, thereby offsetting the gravity generated by the upper glass slide and preventing the next glass slide to be fed from slipping off the support plate 22.

[0038] Furthermore, please refer to Figure 1. The top of the support plate 3 is provided with a horizontal groove 27. The fixing block at the bottom of the rectangular piece 13 slides automatically in the horizontal groove 27, thereby ensuring that the glass slide will not sway left and right in the horizontal groove 27, and ensuring that the rectangular piece 13 is more stable when pushing the glass slide.

[0039] Furthermore, referring to Figure 1, a fixing baffle 28 is also fixed on the top of the support plate 3. The fixing baffle 28 is located above the rectangular plate 13. When the pusher block 5 pushes the glass slide onto the rectangular plate 13, the pusher drive 8 moves backward, and the glass slide moves relative to the fixing baffle 28, thereby pushing the glass slide off the rectangular plate 13 and into the transverse groove 27. Then, the rectangular plate 13 moves forward to push the glass slide in the transverse groove 27 to feed it.

[0040] Example 2: Please refer to Figures 3 and 5. This embodiment further explains Example 1, and the difference lies in optimizing the movement mode of the feeding component 9.

[0041] Specifically, a first slider 10 is fixed to the bottom of the feeding component 9, a first guide rail 11 is slidably connected to the bottom of the first slider 10, and a feeding drive component 12 is installed on one side of the first slider 10; the feeding drive component 12 includes a synchronous wheel 23, two synchronous wheels 23 are installed on the bottom box 4, and a toothed belt 24 is connected between the two synchronous wheels 23 for transmission, and the toothed belt 24 is fixedly connected to the first slider 10.

[0042] Specifically, during the feeding process, an external motor (not shown in the figure) drives one of the synchronous pulleys 23 to rotate, which in turn drives the other synchronous pulley 23 to rotate via the toothed belt 24. One side of the toothed belt 24 will move linearly, causing the first slider 10 to slide on the first guide rail 11, thereby driving the feeding component 9 to move linearly, and thus smoothly moving the glass slide directly below the heat transfer machine for printing.

[0043] Example 3: Please refer to Figure 7. This embodiment further explains Example 2, with the difference being the optimization of the maintenance method for the rack 18.

[0044] Specifically, an L-shaped block 25 is provided on one side of the rack 18, and a sponge block 26 is fixed to the outside of the L-shaped block 25. The sponge block 26 is impregnated with grease. The bottom of the L-shaped block 25 is fixed to the base box 4. The teeth of the rack 18 are in contact with the sponge block 26. When the rack 18 moves towards the L-shaped block 25, the teeth of the rack 18 will contact the sponge block 26, thereby squeezing the sponge block 26. After squeezing, the grease inside the sponge block 26 will be squeezed out. As the rack 18 moves, the grease will be applied to the teeth of the rack 18, thereby lubricating the teeth and playing an automatic maintenance role for the rack 18.
