[0032] In the description of the present application, it should be understood that the terms "left", "right", "front", "back", "up", "down" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.
[0033] The content of the present application will be further described in detail below in conjunction with specific embodiments, Figure 1 A three-dimensional schematic diagram of the vegetarian string forming equipment disclosed by the present application is shown, which can be known that it mainly consists of a machine 1, a sign supply machine 2, a vegetarian roll sign threading machine 3, a vegetarian roll cutting and spreading machine 4, and a vegetarian string taking-down machine 5. Among them, the sign supply machine 2, the vegetarian roll sign threading machine 3, the vegetarian roll cutting and spreading machine 4, and the vegetarian string taking-down machine 5 are all installed on the machine 1 as the installation base, and are arranged in sequence along the upstream and downstream directions. In actual application, the sign supply machine 2 is started to orderly deliver the sign, providing material preparation for subsequent sign threading operation. The vegetarian roll sign threading machine 3 receives the sign and threads it into the vegetarian roll. Then, the vegetarian roll after threading is fed into the vegetarian roll cutting and spreading machine 4 to perform cutting and spreading processing, and the vegetarian string finished product is formed. Finally, the vegetarian string taking-down machine 5 acts to take out the vegetarian string finished product from the vegetarian roll cutting and spreading machine 4, that is, the complete forming process of the vegetarian string is completed.
[0034] It is known that during the operation of the vegetarian roll sign threading machine 3, the batch of vegetarian rolls are sequentially threaded and fed into the vegetarian roll cutting and spreading machine 4. Figure 2 、 Figure 3The utility model discloses two different perspective three -dimensional schematic diagrams of vegetarian roll threading machine, can know, it mainly comprises vegetarian roll feeding device 31, vegetarian roll temporary storage device 32 and vegetarian roll side pushing mechanism 33 and so on several parts. Among them, vegetarian roll temporary storage device 32 is laid out in the upstream of vegetarian roll cutting and spreading machine 4, and with it keeps the direct opposite position. Vegetarian roll feeding device 31 is laid out in the front of vegetarian roll temporary storage device 32, and during its action, vegetarian roll can be supplied to vegetarian roll temporary storage device 32 in the side lying state horizontally. Vegetarian roll side pushing mechanism 33 is also used to match vegetarian roll temporary storage device 32, and during its action, the vegetarian roll of threading finished state can be taken out from vegetarian roll temporary storage device 32 and fed into vegetarian roll cutting and spreading machine 4.
[0035] During its operation, vegetarian roll threading machine 3 can batchly thread each vegetarian roll. Compared with traditional manual threading, manual operation is slow and easy to fatigue, and the vegetarian roll threading machine 3 can continuously and efficiently perform the threading task.
[0036] In practical application, thanks to the vegetarian roll feeding device 31 being laid in front of the vegetarian roll temporary storage device 32, and the vegetarian roll being fed in a side-lying position, on the one hand, the vegetarian roll feeding action is easy to realize, fast and orderly, ensuring the continuity of the vegetarian roll threading link and effectively reducing the time waste caused by waiting for materials, which lays a good foundation for improving the production efficiency of the vegetarian string forming equipment. On the other hand, it effectively avoids the deformation and damage of the vegetarian roll during the feeding process;
[0037] Furthermore, with the assistance of the vegetarian roll side pushing mechanism 33, the threaded vegetarian roll can be quickly taken out from the vegetarian roll temporary storage device 32 and fed into the vegetarian roll cutting and spreading machine 4. The vegetarian roll feeding device 31, the vegetarian roll temporary storage device 32 and the vegetarian roll side pushing mechanism 33 work together, the production process is compact and smooth, and the output of vegetarian strings per unit time is greatly improved.
[0038] As shown in Figure 5 , Figures 11 to 13 The vegetarian roll temporary storage device 32 mainly comprises a force bearing frame 321, a wide type finger air cylinder 322, an upper clamping piece 323 and a lower clamping piece 324. The force bearing frame 321 is placed and fixed on the machine table 1. The wide type finger air cylinder 322 is an integral purchased part, which takes the force bearing frame 321 as the installation base. The upper clamping piece 323 and the lower clamping piece 324 are fixed to the wide type finger air cylinder 322 in a detachable manner and are arranged opposite in the up-down direction. The upper clamping piece 323 and the lower clamping piece 324 respectively form an upper clamping sub-cavity 3231 and a lower clamping sub-cavity 3241 (as shown in Figures 7 to 9The vegetarian rolls are temporarily stored by the vegetarian roll temporary storage device 32 in the threading process, and the circumferential side walls thereof are constrained by the holding mother cavity, so that the phenomenon of relaxation and dispersion of the vegetarian rolls due to the axial threading force can be effectively avoided, and the yield of the products is ensured.
[0039] In particular, it is emphasized that the wide finger cylinder 322 can synchronously perform the opposite displacement movement when working, so that the upper holding sub-cavity 3231 and the lower holding sub-cavity 3241 are quickly folded into the holding mother cavity, the vegetarian rolls are quickly and stably clamped, and the subsequent skewer is more accurately inserted into the vegetarian rolls. After the vegetarian rolls are threaded, the upper holding member 323 and the lower holding member 324 synchronously perform the opposite displacement movement under the driving force from the wide finger cylinder 322, the holding mother cavity is split, the threaded vegetarian rolls lose the constraint force, and are smoothly discharged from the holding mother cavity.
[0040] It is known that the position accuracy of the holding mother cavity is crucial to the production efficiency of the vegetarian string forming equipment, and even to the normal operation. For example, if the position accuracy of the holding mother cavity is out of tolerance, it affects the accurate alignment between the holding mother cavity and the feeding port of the vegetarian roll cutting and spreading machine 4, and further directly relates to whether the threaded vegetarian rolls can be smoothly discharged from the vegetarian roll temporary storage device 32 and fed into the vegetarian roll cutting and spreading machine 4. In addition, if the position accuracy of the holding mother cavity is out of tolerance, it also affects the accurate alignment between the holding mother cavity and the skewer supply machine 2, and further directly relates to whether the skewer can be smoothly transferred from the skewer supply machine 2 to the vegetarian roll temporary storage device 32. Therefore, as a further optimization of the above technical solution, as shown in Figure 5 、 Figure 6 The force bearing frame 321 is fixed to the machine table 1 by means of the first fastener, and the wide finger cylinder 322 is fixed to the force bearing frame 321 by means of the second fastener. The machine table 1 is formed with a first threaded hole for screwing the first fastener, and the wide finger cylinder 322 is formed with a second threaded hole (not shown in the figure) for screwing the second fastener. The force bearing frame 321 is simultaneously formed with a plurality of first waist-shaped holes 3211 adapted to the first fastener and extending along the front-rear direction, and a second waist-shaped hole 3212 adapted to the second fastener and extending along the up-down direction. In actual application, when the position accuracy of the holding mother cavity is out of tolerance, the front-rear position of the force bearing frame 321 can be adjusted according to the actual situation, and the front-rear position of the wide finger cylinder 322 is also synchronously adjusted, or / and the height position of the wide finger cylinder 322 is adjusted, until the position accuracy of the holding mother cavity meets the design requirements.
[0041] It is known that, according to the design common sense, the vegetarian roll side pushing mechanism 33 can take various design structures to achieve the lateral pushing of the vegetarian roll in the finished state, but here a design structure is recommended, which is simple in design, easy to manufacture and implement, and extremely precise in side pushing action. Specifically, as shown in Figures 10 to 13 The vegetarian roll side pushing mechanism 33 mainly consists of a guide beam 331, a side pushing rack 332, a gear 333, and a rotary motor 334. The guide beam 331 is shaped with a guide groove 3311 that matches the side pushing rack 332 (as shown in Figure 11 、 Figure 12 The lower holding member 324 is shaped with an avoidance passage 3242 (as shown in Figure 8 、 Figure 9 The gear 333 is engaged with the side pushing rack 332 and is sleeved on the power output shaft of the rotary motor 334. During the operation of the rotary motor 334, the side pushing rack 332 performs a translational reciprocating motion along the guide groove 3311 due to the engagement force from the gear 333. In a certain period of time, the vegetarian roll is pushed out of the lower holding sub-cavity 3241 due to the side pushing force and fed into the vegetarian roll cutting and spreading mechanism 4; in the next period of time, the side pushing rack 332 performs a retreat action due to the reverse engagement force from the gear 333, reserving space for the vegetarian roll to fall into the lower holding sub-cavity 3241.
[0042] Furthermore, as shown in Figure 10 、 Figure 11 、 Figure 12 The vegetarian roll side pushing mechanism 33 is also provided with a side pushing plate 335. The side pushing plate 335 is vertically built-in the holding cavity and is welded with the free end of the side pushing rack 332. When the side pushing rack 332 performs a translational motion towards the vegetarian roll cutting and spreading mechanism 4, the vegetarian roll is pushed out of the lower holding sub-cavity 3241 due to the direct side pushing force from the side pushing plate 335. In this way, under the premise that the vegetarian roll performs a translational motion due to the side pushing, the side pushing stress distribution on the end part is more uniform, effectively avoiding the damage of the end part of the vegetarian roll due to excessive side pushing stress.
[0043] As shown in Figure 4 、 Figures 11 to 13As shown in the figure, the vegetarian roll feeding device 31 comprises a base 311, a bearing plate 312 and a push-up cylinder 313. The base 311 is installed on the machine table 1. The bearing plate 312 is horizontally placed and fixed on the base 311, and is in a critical top-touch state with the vegetarian roll temporary storage device 32. The push-up cylinder 313 is detachably fixed on the top wall of the bearing plate 312 and faces the vegetarian roll temporary storage device 32. During the working of the push-up cylinder 313, the vegetarian roll placed on the bearing plate 312 and located right behind the push-up cylinder 313 is translated by the side pushing force from the push-up cylinder 313, while the upper holding member 323 and the lower holding member 324 are simultaneously executed with a backward displacement movement by the driving force from the broad finger cylinder 322, and are leveled with the bearing plate 312 until the lower holding member 324, which is beneficial to the vegetarian roll to roll down into the lower holding sub-cavity 3241.
[0044] The above description of disclosed embodiments enables those skilled in the art to carry out or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
