Description

Technical Field

[0001] This utility model relates to the field of cover glass sealing, and in particular to a sealing tape supply and cutting device. Background Technology

[0002] Traditional coverslip mounting equipment can automatically mount tissue sections or cell smears onto coverslips, ensuring long-term sample preservation and improving microscopic examination quality. The mounting process involves many steps, including taking the coverslip, applying adhesive, mounting the slide, and drying. To achieve these actions, the mechanical structure and electrical control system are relatively complex, resulting in a large overall size of the equipment. In recent years, a mounting tape has been introduced to replace the coverslips used in traditional mounting. This tape is coated on one side with a novel adhesive layer that reacts rapidly with high-concentration xylene to mount the sample onto the slide.

[0003] Therefore, automated equipment using adhesive tape for sealing coverslips eliminates the dispensing step inherent in traditional coverlip sealing equipment. Consequently, a suitable device for supplying and cutting the sealing tape needs to be designed. Utility Model Content

Detailed Implementation

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 As shown, an embodiment of this application discloses a feeding and cutting device for sealing tape, including a base plate 1, on which a tape limiting wheel group 2 is provided. A feeding assembly 4 is provided at the lower end of the tape limiting wheel group 2. The feeding assembly 4 includes a guide wheel 41, a primary feeding wheel 42, and a secondary feeding wheel 44 arranged sequentially along the feeding direction. A primary follower wheel 43 is provided under the primary feeding wheel 42. A gap for tape to pass through is provided between the primary feeding wheel 42 and the primary follower wheel 43. A secondary follower wheel 45 is provided under the secondary feeding wheel 44. A gap for tape to pass through is provided between the secondary feeding wheel 44 and the secondary follower wheel 45. The device also includes a first drive motor for driving the primary feeding wheel 42 to rotate and a second drive motor for driving the secondary feeding wheel 44 to rotate. A cutting mechanism 6 is provided between the primary feeding wheel 42 and the secondary feeding wheel 44.

[0026] In actual operation, the sealing tape reel 3 is first placed on the tape limiting wheel group 2. The tape on the sealing tape reel 3 is guided by the guide wheel 41 into the gap between the first-stage feeding wheel 42 and the first-stage follower wheel 43. The tape continues to move forward into the gap between the second-stage feeding wheel 44 and the second-stage follower wheel 45. The second-stage feeding wheel 44 and the second-stage follower wheel 45 tension the tape. When the tape moves to the correct position, the cutting mechanism 6 cuts the tape. The cut tape continues to be transported forward under the action of the second-stage feeding wheel 44.

[0027] This structure is simple and occupies little space. It can achieve continuous and stable tape feeding and cutting. Furthermore, through the independent control of the primary feeding wheel 42 and the secondary feeding wheel 44, the secondary feeding wheel 44 can be used as both a tensioning wheel and a feeding wheel to stably deliver the cut tape. At the same time, the tape feeding speed, feeding speed and cutting length can be changed by adjusting the operating parameters of the motors of both.

[0028] In this embodiment, a primary track 5 and a secondary track 7 are also included. The primary track 5 is located between the primary feeding wheel 42 and the cutting mechanism 6, and the secondary track 7 is located between the machine feeding wheel and the secondary follower wheel 45.

[0029] Specifically, the primary track 5 includes a first upper guide plate 51 and a first lower guide plate 52, and a gap is provided between the first upper guide plate 51 and the first lower guide plate 52 for the tape to pass through.

[0030] The secondary track 7 includes a second upper guide plate 71 and a second lower guide plate 72. A gap is provided between the second upper guide plate 71 and the second lower guide plate 72 for the tape to pass through. The second upper guide plate 71 and the second lower guide plate 72 are respectively provided with through grooves, so that the secondary feeding wheel 44 and the secondary follower wheel 45 can extend into the secondary track 7.

[0031] During operation, the conveyor belt is guided by the guide wheel 41 from the conveyor belt limiting wheel group 2, passes through the primary feeding wheel 42, and then enters the gap between the first upper guide plate 51 and the first lower guide plate 52 of the primary track 5. Under the constraint of the gap, the conveyor belt maintains a stable running path and moves forward. Then, the conveyor belt enters the gap between the second upper guide plate 71 and the second lower guide plate 72 of the secondary track 7. Similarly, under the positioning effect of the gap, the conveyor belt continues to move forward stably. At the same time, when the conveyor belt is in the secondary track 7, under the drive of the secondary feeding wheel 44 and the secondary follower wheel 45, the cut conveyor belt can still continue to be transmitted forward in the secondary track 7.

[0032] In this structure, the primary track 5 and the secondary track 7 are used to position the running path of the conveyor belt, ensuring the stability and accuracy of the conveyor belt's movement.

[0033] In this embodiment, the first-stage track 5 has a flared opening at one end facing the first-stage feeding wheel 42.

[0034] Specifically, this design allows the conveyor belt to enter the primary track 5 more smoothly. The flared structure acts as a guide and transition, preventing the conveyor belt from jamming or deviating due to suddenly entering a narrow gap, and further ensuring the stability and continuity of the conveyor belt.

[0035] In this embodiment, the primary track 5 and the secondary track 7 are arranged at an angle downwards.

[0036] Specifically, the primary track 5 and the secondary track 7 are collinear and form an acute angle with the horizontal plane, so that each piece of tape cut off is attached to the horizontally placed slice at a certain angle when it is fed out by the secondary feeding wheel 44, thereby effectively reducing air bubbles caused by uneven xylene coating during the sealing process.

[0037] In this embodiment, the cutting mechanism 6 includes a motor mounting plate 61 and a cutter mounting plate 62. The middle part of the cutter mounting plate 62 is rotatably connected to the motor mounting plate 61 via a rotating shaft 63. A cutter 64 is provided at the front end of the cutter mounting plate 62, and a roller 65 is provided at the rear end of the cutter mounting plate 62. A spring mounting member 67 is provided between the roller 65 and the rotating shaft 63. The mechanism also includes a return spring 66. One end of the return spring 66 is connected to the spring mounting member 67, and the other end of the return spring 66 is connected to the motor mounting plate 61, so that the cutter mounting plate 62 is tilted up under the action of the return spring 66. A third drive motor 68 is provided on the motor mounting plate 61, and a cam 69 that cooperates with the roller 65 is provided on the third drive motor 68, so that the cutter 64 performs a cutting action.

[0038] Specifically, during the cutting operation, the third drive motor 68 starts, driving the cam 69 to rotate. The rotation of the cam 69 causes it to contact the roller 65 and apply upward pressure. Under this pressure, the roller 65 drives the cutter mounting plate 62 to rotate around the shaft 63, overcoming the force of the return spring 66 and causing the cutter 64 to move downwards to cut the tape. When the cam 69 rotates to a certain angle, its contact point with the roller 65 gradually moves away, reducing the pressure on the roller 65. At this point, the force of the return spring 66 begins to act, pushing the spring mounting piece 67 to cause the cutter mounting plate 62 to rotate upwards around the shaft 63. The cutter 64 then lifts upwards, completing one cutting action. Through the continuous rotation of the third drive motor 68, the cam 69 continuously repeats the above actions, thereby achieving continuous cutting of the tape by the cutter 64.

[0039] In this embodiment, a handle 610 is provided on the end of the cutter mounting plate 62 near the cutter 64.

[0040] Specifically, when the automatic cutting mode malfunctions or a temporary single cut is required, the operator can press the handle 610 to overcome the elasticity of the return spring 66, causing the cutter mounting plate 62 to rotate around the pivot 63, which in turn drives the cutter 64 downward to cut the tape. This design retains the convenience of automatic cutting while increasing the flexibility of manual cutting, ensuring the applicability of the equipment in different situations.

[0041] In this embodiment, the tape limiting wheel group 2 includes a first limiting wheel 21 and a second limiting wheel 22, and the first limiting wheel 21 and the second limiting wheel 22 are located on the same horizontal line.

[0042] Specifically, the first limiting wheel 21 and the second limiting wheel 22 are used to support and restrict the tape reel 3, so that the tape reel 3 can roll freely on the tape limiting wheel group 2 without coming off.

[0043] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
