Description

Technical Field

[0001] The utility model relates to the technical field of food processing equipment, in particular to an automatic material conveying device on an integrated peeling machine. Background Art

[0002] As the pace of modern life accelerates, people's demand for food products is shifting towards convenience, speed, and standardization. Against this backdrop, industrialized food production is becoming a mainstream trend. In China in particular, dough wrappers, such as dumpling wrappers and wonton wrappers, are not only popular among consumers but also enjoy enormous market demand. These wrappers are not only suitable for large-scale industrial processing but also facilitate subsequent packaging and distribution, thus satisfying the modern urbanite's demand for quick, convenient foods.

[0003] Reference is made to the dough production system disclosed in the Chinese utility model patent application number 201810983331.X, which includes a dough conveyor belt, a dough cutting machine, and a residual material separation mechanism. The dough cutting machine is used to cut the dough into multiple groups of dough skins spaced apart along the width direction of the dough conveyor belt; the residual material separation mechanism includes multiple grids spaced apart along the width direction of the dough conveyor belt, the multiple grids are arranged downstream of the dough conveyor belt, and a lifting platform is provided between every two grids; the pushing mechanism is used to push the dough skins from the lifting platform. When the dough skins and residual material are conveyed to the residual material separation mechanism, the dough skins descend together with the lifting platform to separate the dough skins from the residual material. The residual material continues to move forward from the grid under the drive of the dough conveyor belt; the dough skins are pushed to the collection device by the pushing mechanism. After the dough skins are pushed out, the pushing mechanism retracts and the lifting platform is reset to between the grids to prepare for the next separation operation. The entire process of separating the dough skins from the residual material is efficient and does not affect the neatness of the dough skins.

[0004] However, the above production line has the following defects: since the time spent by the skin stacking machine to stack the skin is much longer than the time spent by the skin cutting machine to cut the skin, every time the skin cutting machine completes a skin cutting, it is necessary to wait for the skin stacking machine to stack the skin. This not only affects the skin cutting efficiency, but also wastes a lot of waiting time of the skin cutting machine, and the time cost does not match the benefit. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides an automatic material feeding device on a leather cutting machine.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention, but the present invention is not limited to the following embodiments.

[0029] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0030] In addition, if there are descriptions involving "first" or "second" in the embodiments of the present invention, the descriptions of "first" or "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0031] like Figures 1 to 8As shown, this embodiment discloses an automatic material conveying device on a dough cutting machine, comprising a frame 1, at least one group of transfer platforms 2 movably mounted on the top of the frame 1, and a control device 3 mounted on the frame 1 for controlling the movement of the transfer platform 2. One end of the automatic material conveying device is provided with a dough cutting device 4, and the other end is provided with at least two dough stacking devices 5 in a ratio of at least 1:2 according to the number of transfer platforms 2. The specific number of dough stacking devices 5 can be reasonably arranged after comparing the dough cutting efficiency and the dough stacking efficiency. The control device 3 controls the transfer platform 2 to sequentially convey the stacked dough skins on each dough stacking device 5 to the dough cutting device 4 for cutting. By configuring at least two dough stacking devices 5 and cooperating with the transfer platform 2 to sequentially convey the stacked dough skins to the dough cutting device 4, the dough cutting device 4 can cut the next pile of dough skins without waiting after cutting, thereby enabling the dough cutting device 4 to continuously and uninterruptedly cut the dough skin, thereby saving waiting time, improving production efficiency and reducing production costs.

[0032] In this embodiment, the top of the frame 1 is provided with a guide rail 11 extending in the left and right directions and a rack 12 extending in the direction of the guide rail 11. The transfer platform 2 includes a sliding plate 21 that slides on the guide rail 11, a conveying platform 22 installed on the sliding plate 21 and extending in the front and rear directions, and a drive motor 23 fixed on the sliding plate 21. The driving end of the drive motor 23 is provided with a gear. The driving end of the drive motor 23 passes through the sliding plate 21 from top to bottom and is engaged with the rack 12 through the gear to form a gear and rack mechanism. The control device 3 drives the transfer platform 2 to slide in the direction of the guide rail 11 by controlling the action of the drive motor 23.

[0033] Not limited to the above embodiments, the transfer platform 2 and the frame 1 can also be moved by a synchronous belt mechanism. The drive motor 23 is installed on the frame 1 and is located at one end of the guide rail 11. A synchronous wheel is provided at the other end of the guide rail 11. The driving end of the drive motor 23 and the synchronous wheel are connected by a synchronous belt. The sliding plate 21 is fixedly connected to the synchronous belt. The control device 3 controls the action of the drive motor 23 to drive the sliding plate 21 to move along the guide rail 11, thereby realizing the translation of the transfer platform 2. The synchronous wheel and synchronous belt are conventional components and are therefore not reflected in the accompanying drawings.

[0034] Furthermore, in order to improve the smoothness of the sliding of the sliding plate 21, a roller 211 is provided at the bottom of the sliding plate 21, and the middle part of the rolling surface of the roller 211 is recessed to form a rolling groove 212. The top of the guide rail 11 is provided with a guide groove 111 extending along the length direction, and the inner side of the guide groove 111 is provided with a limiting ridge 112 extending along the length direction at the middle part of the groove wall. The center axis of the roller 211 is arranged perpendicular to the sliding plate 21. After the roller 211 extends into the guide groove 111, the limiting ridges 112 on both sides cooperate to form a limit in the rolling groove 212. Limiting plates are provided at both ends of the guide rail 11 to prevent the roller 211 from leaving the guide groove 111.

[0035] Furthermore, the conveyor platform 22 includes a fixed seat 221 fixed on the sliding plate 21, a conveyor belt 222 installed on the fixed seat 221 and transported in the front and rear directions, and a conveying motor 223 installed on the fixed seat 221. The front and rear ends of the fixed seat 221 are equipped with rotating shafts 224, and the conveyor belt 222 is wrapped around the rotating shafts 224 at both ends. The conveying motor 223 drives the conveyor belt 222 to move by driving the rotating shaft 224 at one end to rotate.

[0036] Furthermore, adjustment holes 220 are provided on the fixing seats 221 on both sides below the conveyor belt 222, and a tensioning shaft 225 is slidably fitted in the adjustment hole 220. The tensioning shaft 225 is pressed against the conveyor belt 222 to tighten the conveyor belt 222, thereby increasing the friction between the conveyor belt 222 and the rotating shaft 224, avoiding sliding friction between the rotating shaft 224 and the conveyor belt 222, and improving the conveying efficiency. When the conveyor belt 222 is tightened, the two ends of the tensioning shaft 225 are fixed to the fixing seat 221 by bolts.

[0037] Furthermore, the conveying end of the conveyor belt 222 is also provided with a sensor device 226 for monitoring whether the dough is completely separated from the conveyor belt 222. The monitoring area of the sensor device 226 is located above the end of the conveyor belt 222 and is fixedly connected to the fixed seat 221 through a bracket. The monitoring signal of the sensor device 226 is transmitted to the control device 3.

[0038] In this embodiment, due to the matching errors between the multiple groups of dough stacking devices 5, there will be position differences between the dough piles on different dough stacking devices 5 after they are transported to the conveyor belt 222, and the transfer platform 2 will transport these dough piles with position differences to the dough cutting device 4, so that the cutting position of the dough pile by the dough cutting device 4 is not uniform. The deviation of the cutting position will cause a large amount of waste in the dough pile, resulting in a decrease in production efficiency and an increase in cost. Therefore, a touch sensing positioning device 6 for sensing the position of the dough pile is also provided on the frame 1, and the device includes a mounting seat 61 fixed on the frame 1, a touch cylinder 62 provided on the mounting seat 61 and a magnetic switch 63 connected to the touch cylinder 62. Specifically, the mounting seat 61 is a "7" shape. shaped structure and the top extends to the top of the conveyor table 22. The touch cylinder 62 is arranged at the extended end of the mounting seat 61. The telescopic end of the touch cylinder 62 is also provided with a touch block 64. The magnetic switch 63 is communicated with the drive motor 23. When the sliding plate 21 moves along the guide rail 11, the dough pile on the conveyor table 22 will collide with the touch block 64. At this time, the touch block 64 will compress the touch cylinder 62 to make the magnetic switch 63 generate an electrical signal, and the magnetic switch 63 will transmit the electrical signal to the drive motor 23 to stop it immediately, thereby making the dough pile stay at the corresponding position. Subsequently, when the conveyor table 22 transports the dough pile to the skin cutting device 4, there will be no position difference, so that the skin cutting device 4 has a certain cutting position on each pile of dough.

[0039] Furthermore, in the process of the conveyor table 22 conveying the dough pile to the dough cutting device 4, the touch block 64 may scratch the dough pile. In order to avoid this situation, an electromagnetic valve switch 65 is provided on the mounting seat 61 for driving the touch cylinder 62 to retract or extend. When the dough pile touches the touch block 64 to generate an electrical signal, the electromagnetic valve switch 65 controls the touch cylinder 62 to retract and move the touch block 64 away from the dough pile. After the dough pile is conveyed away, the electromagnetic valve switch 65 controls the touch cylinder 62 to reset.

[0040] Furthermore, since the dough is relatively soft, a touch signal needs to be generated immediately when the dough pile touches the touch block 64, otherwise the touch block 64 will squeeze the dough pile and damage the dough. Therefore, a pressure regulating valve 66 for adjusting the touch pressure of the touch cylinder 62 is also provided on the mounting seat 61. The pressure regulating valve 66 can also be used to reasonably set the touch pressure for different dough pile products.

[0041] In this embodiment, two groups of transfer platforms 2 are provided on the frame 1 , and each group of transfer platforms 2 is correspondingly configured with two groups of skin stacking devices 5 .
