[0030] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] like Figure 1-Figure 6 As shown, one embodiment of the utility model provides a medical tape cutting device, comprising a box body 1, a cutting mechanism 2, an anti-twisting mechanism, a retaining assembly and a rod body 6 for placing adhesive tape; a discharge port for the adhesive tape to pass through is opened on the side wall of the box body 1, the cutting mechanism 2 is installed on the outer wall of the box body 1 and is close to the discharge port, and the cutting mechanism 2 is used to cut the adhesive tape; the rod body 6, the anti-twisting mechanism and the retaining assembly are successively installed inside the box body 1, and the retaining assembly is close to the cutting mechanism 2; one end of the adhesive tape on the rod body 6 passes through the anti-twisting mechanism, the retaining assembly and the cutting mechanism 2 in sequence; the anti-twisting mechanism is used to filter the adhesive tape to prevent the adhesive tape from twisting, and the retaining assembly is used to retain the adhesive tape passing through the retaining assembly.

[0032] In this embodiment, the tape roll 3 is first inserted onto the rod body 6, and then one end of the tape is pulled so that the tape passes through the anti-twisting mechanism and the retaining assembly in sequence. The anti-twisting mechanism is used to filter and flatten the tape to prevent the tape from twisting. Then, one end of the tape passes through the opening on the side wall of the box body 1 and enters the cutting mechanism 2. When the tape is cut, the retaining assembly retains the tape on the right side of the cutting mechanism 2, and then the nursing staff pulls the tape toward the side away from the cutting mechanism 2, so that the tape between the retaining assembly and the cutting mechanism 2 is in a taut state, and then the cutting mechanism 2 is used to cut the tape.

[0033] In this way, the tape can be cut quickly, the cutting effect is good, time and labor are saved, and the work efficiency is high.

[0034] As a preferred embodiment, Figure 1 and Figure 2As shown, the rod body 6 is a cylindrical rod, one end of the rod body 6 is fixedly mounted on the back inner wall of the box body 1, a baffle is installed on the rod body 6, the baffle is a circular ring plate, and the baffle is coaxially arranged with the rod body 6, the tape roll 3 is sleeved on the rod body 6 and blocked by the baffle.

[0035] Preferably, Figure 2 and Figure 3 As shown, the anti-twisting mechanism includes two rods 104, a first roller 102 and a second roller 103, wherein the same end of the two rods 104 is rotatably mounted on the inner wall of the back of the box 1, one rod 104 is higher than the discharge port, and the other rod 104 is lower than the discharge port, and there is a gap between the two rods 104 for the tape to pass through. Further, the first roller 102 and the second roller 103 are located on the right side of the rod 104, that is, located between the rod 104 and the rod 6, and one end of the first roller 102 and the second roller 103 is rotatably mounted on the inner wall of the back of the box 1, the first roller 102 is higher than the feed port, and the second roller 103 is lower than the feed port.

[0036] When installing the tape roll 3, first put the tape roll 3 on the rod body 6, then pull the free end of the tape roll 3 and bypass the first roller body 102 and the second roller body 103 in sequence, then make the free end of the tape roll 3 pass through the gap between the two rod bodies 104, and finally pull the tape through the feed port into the cutting mechanism 2.

[0037] It should be noted that, since the adhesive tape passes through the first roller 102 and the second roller 103 in sequence, the adhesive tape has a certain tension when it is pulled, and the adhesive tape is not easily twisted. Furthermore, since the twisted part of the adhesive tape itself will be smoothed when the adhesive tape passes through the gap between the two rods 104, the adhesive tape at the cutting position can be better prevented from twisting.

[0038] It should be noted that the adhesive tape used in this embodiment has oil paper pasted on its adhesive surface. Figure 2 From the perspective of FIG. 1 , the upper surface of the adhesive tape portion between the two rods 104 is an adhesive surface, and oil paper is pasted on the adhesive surface. In this way, even if the two rods 104 squeeze the adhesive tape, the two will not adhere to each other. After the adhesive tape is cut off later, the oil paper pasted on the adhesive tape can be torn off to expose the adhesive surface.

[0039] As a preferred embodiment, Figure 2 As shown, the retaining assembly includes a lifting mechanism 5, an upper sphere 505 and a lower sphere 4. The lifting mechanism 5 is installed on the inner wall of the box body 1 and is close to the feed port. The lower sphere 4 is fixed on the inner wall of the box body 1 and is located below the lifting mechanism 5. The upper sphere 505 is installed on the lifting mechanism 5. The lifting mechanism 5 is used to drive the upper sphere 505 to rise and fall. The upper sphere 505 is higher than the discharge port, the lower sphere 4 is lower than the discharge port, and the lower sphere 4 is located directly below the upper sphere 505.

[0040] In this way, the lower sphere 4 is driven downward by the lifting mechanism 5 to reduce the gap between the lower sphere 4 and the upper sphere 505 until the upper sphere 505 squeezes the tape placed on the lower sphere 4.

[0041] It should be noted that the lifting mechanism 5 can adopt a threaded screw lifting method, a cylinder lifting method, an electric guide rail or a linear module lifting method, etc., as long as it can drive the upper ball 505 to move up and down.

[0042] Preferably, Figure 2 and Figure 4 As shown, the lifting mechanism 5 is an electric guide rail, which includes a guide rail 501, a slider 502 and a fixed plate 503. The fixed plate 503 is horizontally fixed on the slider 502. A vertically arranged spring 2 504 is installed at the bottom of the fixed plate 503, and the upper ball 505 is fixed at the bottom of the spring 2 504.

[0043] It should be noted that when cutting, the tape only needs to be kept tight, so there is no need for the retaining assembly to press the tape to avoid damaging it. By adding the second spring 504, a certain buffer can be ensured when the upper ball 505 presses the tape downward to avoid excessive downward pressure.

[0044] Preferably, a controller is installed on the box body 1, and the linear module is electrically connected to the controller, and the operation of the electric guide rail can be controlled by the controller.

[0045] As an alternative embodiment, Figure 3 As shown, the retaining assembly includes a carrier plate 8, a vacuum pump and a negative pressure nozzle 7. The carrier plate 8 is mounted on the side wall of the box body 1, and the negative pressure nozzle 7 is mounted on the carrier plate 8. The top of the negative pressure nozzle 7 is lower than the discharge port, so that the lower surface of the adhesive tape rests on the top of the negative pressure nozzle 7. The vacuum pump and the negative pressure nozzle 7 are connected through an air pipe. In this way, when the adhesive tape is cut, the adhesive tape can be sucked by the negative pressure nozzle 7.

[0046] Preferably, Figure 5 As shown, the cutting mechanism 2 includes a block 201, a cutter 203, a mounting member 202, a punching rod 204 and a spring 205. A through hole is provided in the block 201. The through hole is a rectangular hole. The width of the through hole is greater than the width of the adhesive tape. A blade groove is provided on the inner bottom wall of the through hole. A hole is provided on the inner top wall of the through hole for the punching rod 204 to pass through. The block 201 is mounted on the side wall of the box 1, and the through hole on the block 201 faces the feed hole on the side wall of the box 1.

[0047] Furthermore, the top of spring 1 205 is fixed to the inner top wall of the through hole, and the bottom of spring 1 205 is fixed to the mounting member 202. The cutter 203 is detachably mounted at the bottom of the mounting member 202, and the blade slot is located directly below the cutter 203. The bottom end of the punch rod 204 is inserted from the hole at the top of the block 201 into the through hole.

[0048] Optionally, the mounting member 202 is in the shape of a rectangular plate, a slot for inserting the cutter 203 is provided on the lower surface of the mounting member 202, and a screw hole is provided on the front of the mounting member 202, and the cutter 203 can be connected to the mounting member 202 by screws.

[0049] When cutting the tape, the tape is first fixed by the fixing mechanism, and then the free end of the tape is pulled outward so that the tape in the cutting mechanism 2 is in a taut state. Then the punching rod 204 is pressed downward, and the punching rod 204 pushes the cutter 203 downward to cut the tape. Then the punching rod 204 is released, and under the action of the spring 205, the cutter 203 moves up and resets, and pushes the punching rod 204 upward.

[0050] Optional, such as Figure 1 and Figure 6 As shown, the front of the box body 1 has an opening, the bottom of the box door 101 is hinged to the bottom of the opening by a hinge, and the top of the box door 101 can be buckled with the top of the opening by a latch or a lock. Further, a spring 3 9 is installed on the side of the box door 101 facing the opening, and a limit plate 10 is fixedly installed at one end of the spring 3 9. The limit plate 10 is a circular plate, and the inner diameter of the circular plate is larger than the inner diameter of the rod body 6.

[0051] In this way, when the door 101 is in a closed state, the limiting plate 10 just squeezes the tape roll 3 sleeved on the rod body 6, and cooperates with the baffle on the rod body 6 to limit the tape roll 3 to prevent the tape from shaking or falling.

[0052] Optional, such as Figure 1 , Figure 2 and Figure 3 As shown, a feed port is provided on the inner walls of the left and right sides of the box body 1, a rod body 6 is installed in the middle of the box body 1, two cutting mechanisms 2, two anti-twisting mechanisms, and two retaining components are provided, and two springs 3 9 and two limit plates 10 are also provided on the box door 101. In this way, two tape rolls 3 can be cut at the same time, improving work efficiency. When one tape roll 3 is used up, the other tape roll 3 can still be used.
