Detailed Description

The present invention will be further explained with reference to the following embodiments and accompanying drawings.

In the embodiment, as shown in FIGS. 1 to 7: a push type paper discharging device comprises two rolling clamping assemblies 100 which are arranged in pair and close to each other, a gap between the two rolling clamping assemblies 100 is used for clamping and leading out a roll paper 01, and the push type paper discharging device also comprises a locking piece 200 and a resetting piece 300; the locking member 200 has a first state of locking to prevent the rolling clamp assembly 100 from rotating, a second state of releasing the rolling clamp assembly 100, and a third state of returning from the second state to the first state under the action of the returning member 300. When the locking member 200 of the present embodiment locks the rolling clamping assembly 100, the rolling clamping assembly 100 cannot rotate, the roll paper 01 cannot be discharged, and the paper can be torn; when the locking member 200 is released, the roll paper 01 can be pulled out; and the locking member 200 is re-lockable by the reset member 300. Namely, the process of quantitatively taking paper can be completed by one operation action of the locking piece 200, and the quantitative paper discharge is realized through a purely mechanical structure, so that the cost is lower than that of an electric appliance product, the fault is not easy to occur, and the reliability and the stability of the product are better.

In the embodiment, as shown in FIGS. 3 to 5 and 7: the locking piece 200 is an articulated rod, one end of the locking piece is a locking part 201 matched with the rolling clamping assembly 100, the other end of the locking piece is a pressing part 202, and the reset piece 300 is an elastic piece acting on the articulated rod. The pressing portion 202 of the present embodiment extends from the housing assembly 500 to facilitate the pressing operation, and the reset member 300 is a tension spring. Pressing the pressing portion 202, i.e., the second state shown in fig. 5B, and releasing the pressing portion 202, the restoring member 300 rebounds, i.e., the third state shown in fig. 5C.

In the embodiment, as shown in fig. 4 and 5: the locking portion 201 is a toothed structure, and in the first state, the linked gear on the rolling clamping assembly 100 is engaged and locked with the locking portion 201. The locking portion 201 in this embodiment is indirectly engaged with the rolling clamp assembly 100 for locking. Locking portion 201 adopts dentate structure, is convenient for with gear structure's locking with throw off, the dead condition of card is difficult to appear.

In the embodiments, as shown in FIGS. 2 to 5: in the third state, the locking member 200 drives the rolling clamping member 100 to rotate through the one-way transmission member 400, and the rotation direction of the rolling clamping member 100 is consistent with the paper discharging direction of the roll paper 01. In the third state, the reset member 300 is used as a power to drive the rolling clamp assembly 100 to rotate in turn, and manual paper pulling is not needed, so that the operation is very convenient. The one-way transmission assembly 400 means that the pressing down of the lock member 200 in the second state does not drive the rolling clamp assembly 100 to rotate, and this structure can prevent the roll paper 01 from accumulating in the housing assembly 500.

In the embodiment, as shown in fig. 3 and 4: the unidirectional transmission assembly 400 is of a unidirectional gear set structure or a ratchet structure. The unidirectional transmission assembly 400 can be realized in various ways, in the unidirectional gear set structure adopted in this embodiment, at least one intermediate gear 401 in the unidirectional gear set has a floating rotating shaft, and can float in the axial direction or the radial direction, the pressing down of the locking member 200 in the second state can move the position of the intermediate gear 401, so that the intermediate gear is separated from each meshing gear and cannot transmit, and the resetting of the locking member 200 in the third state can also reset the intermediate gear 401 to recover the transmission function, so that the unidirectional transmission is realized. In addition, the present embodiment can also adopt a ratchet structure to realize one-way transmission. The technical means are mature technologies.

In the embodiment, as shown in fig. 3 and 4: the one-way transmission assembly 400 is a multi-stage reduction mechanism. The number of stages and the transmission ratio of the unidirectional transmission assembly 400 of this embodiment can be designed according to actual requirements, and generally requires that the locking member 200 rotates a certain angle, and the rolling clamping assembly 100 can rotate for many cycles, so that it can be ensured that paper of sufficient length is pulled out by one action of the rolling clamping assembly 100.

In the example, as shown in fig. 7: the locking member 200 is a hinged rod, and one end of the hinged rod is provided with a sector gear portion 203, and the sector gear portion 203 is a power output section of the one-way transmission assembly 400. In the structure of this embodiment, the locking member 200 can directly drive the unidirectional transmission assembly 400 and the rolling clamping assembly 100 to rotate through the sector gear portion 203, and the structure is compact and the motion reliability is high.

In the examples, as shown in fig. 1: the roll paper roll clamping device further comprises a shell assembly 500 and a roll paper assembly 600, wherein the roll paper assembly 600 is used for placing roll paper 01, and the roll clamping assembly 100, the locking member 200, the resetting member 300, the one-way transmission assembly 400 and the roll paper assembly 600 are all installed in the shell assembly 500. The housing assembly 500 of the present embodiment is an openable cover structure, and can protect the roll paper 01 and the internal structure, and the roll paper assembly 600 is a rotating shaft structure, and the roll paper 01 can rotate around the roll paper assembly 600.

In the example, as shown in fig. 6: the rolling clamping assembly 100 comprises a roller 101, and an anti-slip sleeve 102 with a plurality of elastic protrusions is arranged on the outer portion of the roller 101. The structure can ensure that the roll paper 01 can be uniformly contacted with the roller 101 along the axial direction, avoid the situation that the two rollers 101 are tight and loose at one time due to the error of the appearance and the axle center of the roller 101, and ensure smooth paper discharge. In addition, the drum 101 may be replaced by another type of rotating member, and it is only necessary to maintain a good contact with the roll paper 01.

It is obvious that the above embodiments of the present invention are only examples for illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. There is no need or no way to give poor examples of all embodiments. And that such obvious changes and modifications are within the scope of the present invention as defined by the appended claims.
