It is recorded in the specification that "the finished product receiving structure 503 includes a finished product collecting rack 509, a finished product downward moving rack 510, a finished product receiving left frame 511 and a finished product receiving right frame 512. The finished product downward moving rack 510 moves along the vertical direction on the finished product collecting rack 509. A finished product receiving cylinder 513 is installed on the finished product downward moving rack 510. A finished product left connecting plate 514 is hinged between the driving end of the finished product receiving cylinder 513 and the finished product receiving left frame 511. A finished product right connecting plate 515 is hinged between the driving end of the finished product receiving cylinder 513 and the finished product receiving right frame 512. Both the finished product receiving left frame 511 and the finished product receiving right frame 512 are hinged on the finished product downward moving rack 510". This finished product receiving structure 503 is the previous generation structure of this application.

The arc-shaped guide rail 221 is used to guide the arc-shaped material receiving frame 220 when the arc-shaped material receiving frame 220 reciprocally moves around the moving center a.

[0030] Compared with the prior art, one or more of the above technical solutions in the product transfer mechanism provided by the embodiment of the present invention at least have one of the following technical effects:

[0031] Referring to Figure 2 and Figure 3 , during operation, the driving component 230 drives the two arc-shaped material receiving frames 220 to reciprocally move around the moving center a, so that the lower ends of the two arc-shaped material receiving frames 220 approach or move away from each other. When the lower ends of the two arc-shaped material receiving frames 220 approach each other, the two arc-shaped material receiving frames 220 perform a closing action, and products (such as crayons, etc.) enter the two arc-shaped material receiving frames 220 from the front side of the two arc-shaped material receiving frames 220; when releasing the products, the lower ends of the two arc-shaped material receiving frames 220 move away from each other and open to form a discharging port, and the two arc-shaped material receiving frames 220 perform an opening action, and the products located in the two arc-shaped material receiving frames 220 fall into the material box from the discharging port. During the process of the two arc-shaped material receiving frames 220 reciprocally moving around the moving center a, the arc-shaped guide rail 221 slides to guide the arc-shaped material receiving frame 220, so that the arc-shaped material receiving frame 220 moves smoothly and smoothly, the structure is stable, and the service life is improved.

[0032] Among them, the arc-shaped guide rail 221 can be fixed to the upper end of the arc-shaped material receiving frame 220 by means of screwing or welding, etc.

[0033] Further, referring to Figure 2 and Figure 3 , the mounting frame 210 is provided with a guide groove 212, and the arc-shaped guide rail 221 is slidably connected to the guide groove 212, so that the arc-shaped material receiving frame 220 is stably slidably connected to the mounting frame 210 through the cooperation of the arc-shaped guide rail 221 and the guide groove 212.

[0034] Further, referring to Figure 2 and Figure 3, two sets of guiding structures are provided at the lower end of the mounting bracket 210. Two arc-shaped guide rails 221 are respectively fixed at the upper ends of the two arc-shaped material receiving frames 220 and are respectively arranged corresponding to the two sets of guiding structures. Each set of guiding structures includes at least a pair of guiding members 211. Guide grooves 212 are provided on the peripheral walls of each pair of guiding members 211. The opposite sides of the arc-shaped guide rail 221 are respectively slidably connected in the corresponding two guide grooves 212. During operation, driven by the driving component 230, the arc-shaped guide rail 221 moves along the corresponding two guide grooves 212, so that the arc-shaped material receiving frame 220 moves stably, and the structure is stable.

[0035] Further, referring to Figure 2 and Figure 3 , the guide groove 212 is a V-shaped or U-shaped guide groove. V-shaped or U-shaped guide strips are provided on the opposite sides of the arc-shaped guide rail 221 along its extending direction. Each guide strip is correspondingly slidably connected in a guide groove, so that the arc-shaped guide rail 221 is positioned and installed in the corresponding guide groove 212 and can move smoothly along the corresponding guide groove 212, and the structure is stable.

[0036] Further, referring to Figure 2 and Figure 3 , the guiding member 211 is a roller. The center of the guiding member 211 is rotatably arranged at the lower end of the mounting bracket 210 through a rotating shaft. The rotating shaft can be fixed to the lower end of the mounting bracket 210 by means of screwing or welding. A circle of guide grooves 212 is provided on the peripheral wall of the guiding member 211. Specifically, when the arc-shaped guide rail 221 moves along the corresponding guide groove 212, the guiding member 211 being a roller will rotate, which can reduce the friction between the arc-shaped guide rail 221 and the guide groove 212, with less wear, improve the service life, and the arc-shaped guide rail 221 moves smoothly.

[0037] In another embodiment of the present utility model, referring to Figure 2 and Figure 3, the driving component 230 includes a first driving unit 231, a gear 232 and two arc-shaped racks 233.

The first driving unit 231 is arranged on the mounting frame 210, the axis of the gear 232 is fixedly arranged on the output shaft of the first driving unit 231, and the gear 232 is located between the two arc-shaped racks 233 and is meshed and connected with the two arc-shaped racks 233. Specifically, the first driving unit 231 drives the gear 232 to rotate, thereby driving the two arc-shaped racks 233 to reciprocate, and further driving the two arc-shaped material receiving frames 220 to reciprocate around the moving center a. When the lower ends of the two arc-shaped material receiving frames 220 approach each other, the two arc-shaped material receiving frames 220 perform a closing action. When the lower ends of the two arc-shaped material receiving frames 220 move away from each other, the two arc-shaped material receiving frames 220 perform an opening action. The method of driving the arc-shaped material receiving frame 220 by the cooperation of the first driving unit 231, the gear 232 and the rack has less jitter or vibration, less noise and more stable movement compared with the method of driving the arc-shaped material receiving frame 220 by the cooperation of a cylinder and a connecting rod in the prior art.

[0038] Among them, the first driving unit 231 can be a rotary cylinder or a motor, etc., which is not limited herein.

[0039] Furthermore, the arc-shaped rack 233 and the arc-shaped material receiving frame 220 are of an integral structure or a split combined structure, which is not limited herein.

[0040] Furthermore, referring to Figure 2 and Figure 3 , a feeding port is formed between the front sides of the two arc-shaped material receiving frames 220. When the lower ends of the two arc-shaped material receiving frames 220 approach each other and close, products (such as crayons, etc.) can enter the two arc-shaped material receiving frames 220 from the feeding port. A baffle plate 240 is arranged at the rear sides of the two arc-shaped material receiving frames 220. The baffle plate 240 positions the products entering the two arc-shaped material receiving frames 220 to prevent the products from passing through the two arc-shaped material receiving frames 220. Preferably, there is a gap between the baffle plate 240 and the two arc-shaped material receiving frames 220, and the arc-shaped material receiving frames 220 will not contact the baffle plate 240 during the movement of the arc-shaped material receiving frames 220, so that the arc-shaped material receiving frames 220 move smoothly. Among them, the baffle plate 240 can be arranged on the mounting frame 210 or the vertical frame 110 of the transfer assembly 100.

[0041] In another embodiment of the present invention, referring to Figure 1, the transfer assembly 100 includes a vertical frame 110, a second driving unit 120, a linear guide rail 130, a synchronous belt 140, and two synchronous pulleys 150. The centers of the two synchronous pulleys 150 are respectively rotatably arranged on the upper and lower sides of the vertical frame 110 through mounting shafts, and the synchronous belt 140 is suitably sleeved outside the two synchronous pulleys 150. The second driving unit 120 is arranged on the vertical frame 110, and the output shaft of the second driving unit 120 is fixedly connected to one of the mounting shafts. The linear guide rail 130 is vertically arranged on the vertical frame 110, and the mounting frame 210 is slidably connected to the linear guide rail 130 through at least one slider 131. The mounting frame 210 is fixedly connected to the synchronous belt 140 through a connecting member 213. Specifically, the second driving unit 120 drives the synchronous pulley 150 to rotate to drive the synchronous belt 140 to rotate, thereby driving the mounting frame 210 to move up and down along the linear guide rail 130, and further driving the two arc-shaped material receiving frames 220 to move up and down. When it is necessary to unload the product, the driving member 230 drives the lower ends of the two arc-shaped material receiving frames 220 to approach each other to close. The product (for example, crayons, etc.) enters the two arc-shaped material receiving frames 220 from the front side of the two arc-shaped material receiving frames 220. Then, the second driving unit 120 drives the two arc-shaped material receiving frames 220 together with the product to move down along the linear guide rail 130 to the material box. Then, the driving member 230 drives the lower ends of the two arc-shaped material receiving frames 220 to move away from each other to open and form a discharge port. The product located in the two arc-shaped material receiving frames 220 falls from the discharge port into the material box, realizing the unloading of the product into the material box.

[0042] Among them, the second driving unit 120 can be a rotary cylinder or a motor, etc., which is not limited here.

[0043] In another embodiment, the transfer assembly 100 is a horizontal transfer mechanism, and the horizontal transfer mechanism is used to drive the opening and closing assembly 200 to move horizontally. For example, the horizontal transfer mechanism can be a linear module, etc.

[0044] In another embodiment of the present invention, an automatic crayon forming machine is further provided, which has the above-mentioned product transfer mechanism. Therefore, the automatic crayon forming machine also has the technical effects of the product transfer mechanism: Refer to Figures 1 - 3 , during the reciprocating movement of the two arc-shaped material receiving frames 220 around the movement center a, the arc-shaped guide rail 221 is used to guide the arc-shaped material receiving frames 220, so that the arc-shaped material receiving frames 220 move smoothly and stably, and the structure is stable, improving the service life.
