[0040] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0041] Example 1: See Figures 1 to 7 As shown, a sign pushing mechanism includes a sign pushing plate 51 and a sign pushing driving mechanism 52, wherein the sign pushing plate 51 and the sign pushing driving mechanism 52 are installed on a machine platform 1, wherein a top plate 11 is provided on the top of the machine platform 1, wherein a strip groove 12 is provided on the top plate 11, wherein the sign pushing plate 51 is movably arranged in the strip groove 12, wherein the sign pushing driving mechanism 52 drives the sign pushing plate 51 to move along the strip groove 12, wherein the top surface of the sign pushing plate 51 is arranged above the top of the strip groove 12, and a sign pushing groove 510 is provided on the top of the left end of the sign pushing plate 51;

[0042] The machine platform 1 at the right end of the push-sign board 51 is also provided with a push-sign limiting mechanism;

[0043] The push-sign limiting mechanism includes a housing 531 and a limiting pin 532. A cavity 533 communicating with the right end of the strip groove 12 is provided inside the housing 531. When the push-sign plate 51 moves to the right, the right end of the push-sign plate 51 moves into the cavity 533.

[0044] Two limiting holes 534 are arranged on the housing 531 at intervals, and the two ends of the limiting holes 534 respectively penetrate the front end surface and the rear end surface of the housing 531, and the middle part of the limiting holes 534 is connected with the cavity 533;

[0045] The limiting pin 532 is inserted into one of the limiting holes 534 . When the push plate 51 moves to the right, the right end of the push plate 51 abuts against the limiting pin 532 .

[0046] In the present embodiment, the push stick mechanism is used to push the stick material (bamboo stick or wooden stick), and the stick material is pushed to the left by the push stick mechanism and penetrated into the gluten, so as to realize the sticking action of the gluten. Among them, a stick delivery component is arranged above the strip groove, and the stick material is sequentially delivered to the push stick plate by the stick delivery component, and then the stick material is pushed to the left and the gluten is pierced by the movement of the push stick plate. Among them, when the push stick mechanism is used, the push stick driving mechanism first drives the push stick plate to move to the right, until the right end of the push stick plate is against the limit pin, and the push stick plate cannot continue to move to the right after the limit pin is limited, at this time, the stick delivery component of the gluten piercing device will drop the stick material, and the right end of the bottom stick material falls into the push stick slot, and then the push stick driving mechanism drives the push stick plate to move to the left, and the stick material is pushed to move to the left by the left end of the push stick slot, and when the stick material moves to the left, the tip of the left end of the stick material will penetrate into the gluten, so as to realize the sticking action of the gluten. After the sticking is completed, the stick pushing driving mechanism drives the stick pushing plate to move to the right until the right end of the stick pushing plate is against the limiting nail, returns to the original position, and waits for the next stick pushing action. Wherein, in the present embodiment, due to different gluten, the required stick material length is different, and the most common gluten on the market generally has large gluten and small gluten, the stick material length of large gluten is 350mm, and the stick material length of small gluten is 300mm. Therefore, if it is necessary to push the stick material of 300mm length, the limiting nail is inserted into the limiting hole on the left side, so that the left end position of the stick material is fixed, and when the stick material falls downward, its right end will fall into the stick pushing groove, and the stick pushing plate is smoothly pushed to the left. When it is necessary to push the stick material of 350mm length, the limiting nail is inserted into the limiting hole on the right side, the left end position of the stick material is unchanged, and when the stick material falls downward, its right end will fall into the stick pushing groove, and the stick pushing plate is smoothly pushed to the left. Therefore, in this embodiment, when it is necessary to push the sign materials of different lengths, the position of the limit pin is adjusted, and the reset of the push sign plate can be mechanically limited, so as to ensure that when the push sign plate moves to the left, it can push the sign materials to the left in the first time to thread the gluten. If the push sign plate does not move enough to the right, the right end of the sign material will not fall into the push sign slot, and when the push sign plate is pushed to the left, the push sign plate cannot push the sign material to the left normally. If the push sign plate moves too much to the right, after the sign material falls downward, when the push sign plate moves to the left, the push sign plate needs to move a certain distance to the left before it can push the sign material to the left through the push sign slot to thread the sign. It takes longer time, and the energy consumption required by the push sign driving mechanism is also higher, which not only affects the efficiency of threading the gluten, but also increases energy consumption and costs. Therefore, in this embodiment, by setting two limiting holes and a limiting pin, the push-sign board can be accurately mechanically limited after being reset, which can not only shorten the moving distance of the push-sign board and improve the efficiency of threading, but also save energy consumption and reduce costs.

[0047] See also Figure 5As shown, the two ends of the limiting pin 532 are respectively arranged outside the two ends of the limiting hole 534, and one end of the limiting pin 532 is provided with a screw head 535, and the screw head 535 is arranged on one side of the shell 531. The other side of the shell 531 is also provided with a magnet 536, and one end of the magnet 536 is adsorbed and connected with the limiting pin 532 exposed at the other end of the limiting hole 534, and the magnet 536 can also be adsorbed on the side wall of the shell 531.

[0048] In this embodiment, the diameter of the screw head is larger than the diameter of the limiting hole, the magnet is a cylindrical magnet, the diameter of the magnet is larger than the diameter of the limiting hole, and the shell and the limiting nail are made of metal materials that can be adsorbed by the magnet, such as iron. The limiting nail itself is radially limited by the limiting hole, one end of it is axially limited by the screw head, and the other end only needs to be axially limited. Therefore, the limiting nail is limited by a magnet instead of a nut, which has the following advantages:

[0049] The magnet itself has magnetic attraction, and its diameter is larger than the limiting hole. Therefore, when the limiting pin wants to move axially toward the screw head, the magnet will also move with it. If the magnet is directly adsorbed on the end of the limiting pin, when the end of the limiting pin retracts into the limiting hole, the end of the magnet will also be adsorbed on the shell, so that the end of the limiting pin will be axially limited by the magnet; if the magnet is adsorbed on the outer surface of the limiting pin exposed outside the limiting hole, at this time, one end of the magnet is adsorbed on the limiting pin, and the outer surface on the side is adsorbed on the shell, which can also achieve circumferential limitation of the limiting pin. In this way, the magnet can be quickly installed and positioned with the limiting pin. When the position of the limiting pin needs to be quickly adjusted, it is only necessary to apply a certain external force to separate the magnet and the limiting pin, so that the limiting pin can be taken out of the limiting hole, and then re-inserted into another limiting hole, and then the magnet is quickly adsorbed on the limiting pin to achieve rapid positioning of the limiting pin, that is, the visual limiting pin can be quickly installed and disassembled.

[0050] At the same time, for places with small operating spaces, if nuts are used, it is inconvenient to disassemble and assemble the nuts, the operating space is small, and tools are not convenient to operate. Magnets can quickly install, limit, disassemble and separate the limit pins without the help of tools. In addition, if the nut falls loose, or the nut and the limit pin fall off during installation, disassembly or use (falling during use: the operation of the equipment will generate vibration, long-term vibration, the screw connection between the nut and the limit pin loosens and falls off), especially if it falls into some small gaps inside the equipment, it is inconvenient to find. If magnets are used, even if the magnet falls or separates from the limit pin, it will be adsorbed on the machine near the shell or the limit hole (most of the machines are made of metal materials that can be magnetically adsorbed), which is easy to find and will not be lost. At the same time, it will not fall into other running mechanisms and will not affect the normal operation of other mechanisms.

[0051] See also Figure 6 As shown, the stick pushing driving mechanism 52 includes a stick pushing motor 521 and a stick pushing gear 522. The stick pushing motor 521 is installed on the machine platform 1, and the stick pushing motor 521 is configured to drive the stick pushing gear 522 to rotate;

[0052] A sign pushing rack 523 is provided at the bottom of the sign pushing plate 51, and the top of the sign pushing gear 522 is meshed with the sign pushing rack 523. When the sign pushing motor 521 drives the sign pushing gear 522 to rotate, the sign pushing plate 51 is driven to move along the strip groove 12 via the sign pushing gear 522 and the sign pushing rack 523.

[0053] In this embodiment, the push sign motor drives the gear to rotate, and since the gear is meshed with the rack at the bottom of the push sign board, when the gear rotates, it drives the push sign board to move along the strip groove. The moving direction of the push sign board is adjusted according to the rotation direction of the gear.

[0054] See also Figures 2 to 4 As shown, a push sign return detection mechanism is also provided on the machine platform at the right end of the push sign board 51, and the push sign return detection mechanism includes two groups of sensors 54 and a sensor switching switch 55 electrically connected to the two groups of sensors 54.

[0055] A detection clearance groove 537 is provided on the top of the shell 531 on the left side of each of the limiting holes 534. The middle of the detection clearance groove 537 is connected to the cavity 533, and the two ends of the detection clearance groove 537 are respectively connected to the front end surface and the rear end surface of the shell 531.

[0056] Each of the sensors 54 is disposed opposite to one of the detection clearance slots 537 .

[0057] In this embodiment, in order to ensure that after the push-stick plate is reset to the predetermined position, the other mechanisms of the gluten stick threading equipment can know the position and the push-stick plate is returned to the position, so as to be able to perform the next stick delivery action or the next stick threading action, at the same time, after the push-stick plate is reset, the push-stick motor also stops working and temporarily does not drive the gear to rotate to drive the push-stick plate to move to the right. By setting a push-stick return detection mechanism, two groups of sensors are used to respectively detect the return position of the push-stick plate, and the sensor switching switch is used to control which group of sensors are used to work. If it is necessary to thread the 300mm stick material, the sensor on the left is controlled to work, and the sensor on the right is not working. At this time, the limit pin is inserted into the limit hole on the left. When the push motor drives the push plate to move to the right, when the right end of the push plate is against the limit pin, it is facing the detection and clearance groove on the left. At this time, the sensor detects the push plate, and it will feed back the data to the controller of the gluten stick threading equipment. The controller controls the work of other mechanisms. For example, the stick feeding component can feed the next stick material into the strip groove, and the push motor stops working. In this way, electrical detection of the push plate's return can be achieved. If it is necessary to pass the 350mm stick material, the sensor on the right is controlled to work, and the sensor on the left is not working. In this way, when the push plate moves to the right and passes the detection and clearance groove on the left, the sensor on the left is not working and will not detect. Only when the right end of the push plate moves to the detection and clearance groove on the right, the sensor on the right detects the push plate, indicating that it has returned to its position. Of course, when the switch sensor is working, it is also necessary to adjust the limit pin and insert it into the corresponding limit hole.

[0058] See also Figure 2 , 4 As shown, the sensor 54 is a through-beam sensor, which includes a receiving end 541 and a transmitting end 542 . The receiving end 541 and the transmitting end 542 are respectively arranged on both sides corresponding to the detection yielding slot 537 , and the receiving end 541 is arranged opposite to the transmitting end 542 .

[0059] A through-beam sensor is used, with signals sent out by the transmitter and received by the receiver. When the push-sign board has not moved to the detection gap, the receiver can normally receive the signal sent out by the transmitter, indicating that the push-sign board has not moved to the right into position. After the push-sign board moves to the right into position, it will be in the detection gap, blocking the space between the receiver and the transmitter. The signal sent out by the transmitter is blocked by the push-sign board, and the receiver cannot receive the signal. Then the data will be fed back to the controller of the gluten threading device, indicating that the push-sign board is reset into position.

[0060] See also Figures 1 to 6As shown, a sensor mounting plate 56 is respectively provided on the front and rear sides of each of the detection clearance slots 537 , and the receiving end 541 and the transmitting end 542 of each of the sensors 54 are respectively mounted on the sensor mounting plates 56 on both sides of the detection clearance slots 537 .

[0061] The sensor switching switch 55 is installed on a sensor mounting plate 56 .

[0062] In this embodiment, the sensor mounting plate is used for installing the sensor and the sensor switching switch, so that the sensor can be arranged directly facing the detection clearance slot.

[0063] See also Figures 1 to 7 As shown, the machine 1 is provided with two mutually parallel guide rail components 511, the strip groove 12 is arranged just above the two guide rail components 511, and the lower movement of the push plate 51 is arranged between the two guide rail components 511;

[0064] The left end of the housing 531 is connected to the right ends of the two guide rail components 511 .

[0065] The arrangement of the two guide rail components can guide the movement of the sign-pushing plate, so that it can only move between the two guide rail components and stably push the sign material.

[0066] See also Figure 7 As shown, the inner side walls of the two guide rail components 511 are respectively provided with oppositely arranged guide grooves 512, the guide grooves 512 are arranged parallel to the extension direction of the guide rail component 511, and the two ends of the guide grooves 512 are respectively connected to the left end and the right end of the guide rail component 511.

[0067] At least two installation holes 513 are disposed on the push-sign plate 51 at intervals in a horizontal direction. A limiting pin 514 is installed in at least two installation holes 513 . Two ends of the limiting pin 514 are respectively pressed against the guide grooves 512 at two sides.

[0068] In this embodiment, if only the guide rail component is provided, the guide rail component can only limit the forward and backward freedom of the push-sign board, and the upward and downward freedom of the push-sign board cannot be limited. Therefore, the provision of the guide groove and the limit pin can limit the upward and downward movement of the push-sign board, so that the gear is always engaged with the rack, and the push-sign board can only move left and right. Furthermore, the diameter of the limit pin matches the height of the guide groove, the limit pin is rotatably connected to the mounting hole, and the outer surface of the limit pin contacts the top and bottom surfaces of the guide groove, so that when the push-sign board moves left and right, the limit pin and the guide groove are in rolling contact, so as to ensure the smoothness and stability of the movement of the push-sign board.

[0069] At the same time, when the push-sign board needs to be disassembled, it is directly pulled to the right to separate it from the guide rail component, which is convenient for maintenance and replacement, and also easy for installation.

In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.
