Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0031] Please refer to the drawings in the embodiments of the present application Figure 1 to the drawings in the embodiments of the present application Figure 8The embodiment provides an automatic positioning blow molding feeding device, which comprises a transfer seat 1, a transfer mechanism 2, a rotating mechanism 3 and a positioning mechanism 4; the transfer seat 1 is provided with a parison positioning mounting part 11 and a positioning protrusion 12; the transfer mechanism 2 comprises a transfer guide rail 21, the transfer guide rail 21 comprises a heating conveying section 211, a blow molding conveying section 212 and a positioning conveying section 213 arranged between the heating conveying section 211 and the blow molding conveying section 212; the rotating mechanism 3 is connected with the transfer seat 1 and used for driving the transfer seat 1 to rotate; the positioning mechanism 4 comprises a first positioning module 41 arranged on the positioning conveying section 213, the first positioning module 41 is provided with a first limiting side wall 410, the first limiting side wall 410 is arranged along the conveying direction of the positioning conveying section 213, and the distance between the first limiting side wall 410 and the rotating shaft of the transfer seat 1 is less than the distance between the positioning protrusion 12 and the rotating shaft of the transfer seat 1; when the transfer mechanism 2 drives the transfer seat 1 to pass through the first positioning module 41, the rotating mechanism 3 drives the transfer seat 1 to rotate until the positioning protrusion 12 abuts against the first limiting side wall 410. The automatic positioning blow molding feeding device provided by the embodiment is characterized in that: the tubular plastic parison 6 is positioned and mounted in the parison positioning mounting part 11 on the transfer seat 1, the tubular plastic parison 6 is heated and softened in the heating work station 7 of the heating conveying section 211, then passes through the positioning conveying section 213 and enters the blow molding work station 8 of the blow molding conveying section 212, when the tubular plastic parison 6 passes through the positioning conveying section 213, the rotating mechanism 3 drives the transfer seat 1 to rotate until the positioning protrusion 12 on the transfer seat 1 abuts against the first limiting side wall 410 on the first positioning module 41, the cooperation of the rotating mechanism 3, the positioning protrusion 12 and the first positioning module 41 enables the transfer seat 1 to realize automatic positioning during the transfer process, so that the positioning part 61 on the tubular plastic parison 6 can keep a unified direction when entering the blow molding work station 8 after passing through the positioning conveying section 213, the structure is ingenious, the positioning efficiency is high, and the continuous automatic and standardized production can be realized.

[0032] The first positioning module 41 is provided with an import end 411 and an export end 412, the distance between the first limiting side wall 410 and the rotating shaft of the transfer seat 1 is less than the distance between the positioning protrusion 12 and the rotating shaft of the transfer seat 1, when the transfer seat 1 is transferred to be close to the first positioning module 41, the rotating mechanism 3 drives the transfer seat 1 to rotate, some positioning protrusions 12 on the transfer seat 1 just avoid the import end 411 and abut against the first limiting side wall 410 automatically along with the rotation of the transfer seat 1 to realize automatic positioning, and a small number of positioning protrusions 12 on the transfer seat 1 just contact the front end face of the import end 411 and cannot abut against the first limiting side wall 410 along with the rotation of the transfer seat 1.

[0033] In order to further realize automatic positioning, the lower end surface of the guide-in end 411 is provided with a guide-in slope 4111. When the rotating mechanism 3 drives the transfer seat 1 to rotate to the position where the positioning protrusion 12 contacts the front end surface of the guide-in end 411, the positioning protrusion 12 passes through the guide-in end 411 along the guide-in slope 4111 and abuts against the first limiting side wall 410. When the transfer seat 1 is transferred to the position close to the first positioning module 41 and the transfer seat 1 is rotated to the position where the positioning protrusion 12 just contacts the front end surface of the guide-in end 411, with the continuous rotation of the transfer seat 1, the positioning protrusion 12 moves along the guide-in slope 4111 and generates a slanting thrust on the guide-in slope 4111, thereby lifting the first positioning module 41. Thus, the positioning protrusion 12 can smoothly pass through the guide-in end 411 and, with the continuous rotation of the transfer seat 1, move to abut against the first limiting side wall 410. By providing the guide-in slope 4111 on the lower end surface of the guide-in end 411 of the first positioning module 41, no matter what position the positioning protrusion 12 is rotated to when the transfer seat 1 is close to the first positioning module 41, the positioning protrusion 12 can move to abut against the first limiting side wall 410 with the rotation of the transfer seat 1, thereby realizing automatic positioning.

[0034] Further, the first positioning module 41 is provided with a plurality of weight-reducing holes 413. If the weight of the first positioning module 41 is too large, the positioning protrusion 12 is difficult to lift the first positioning module 41 when moving along the guide-in slope 4111 or the positioning protrusion 12 is difficult to continue moving when moving along the guide-in slope 4111. Therefore, the appropriate weight of the first positioning module 41 is particularly important. In the embodiment, the weight-reducing holes 413 are arranged on the first positioning module 41 to make the weight of the first positioning module 41 be lifted by the positioning protrusion 12 and at the same time not affect the continuous movement of the positioning protrusion 12. The size and number of the weight-reducing holes 413 can be obtained by multiple tests according to the actual situation of the first positioning module 41.

[0035] Further, in order to make the positioning protrusion 12 more smoothly pass through the guide-in slope 4111, the front of the guide-in slope 4111 is provided with a first guide-in arc surface 4112 and the rear of the guide-in slope 4111 is provided with a second guide-in arc surface 4113. The curvature of the first guide-in arc surface 4112 is greater than that of the second guide-in arc surface 4113. The first guide-in arc surface 4112 connects the front end surface of the guide-in end 411 and the guide-in slope 4111 and has a large curvature, which can make the positioning protrusion 12 smoothly enter the guide-in slope 4111 from the front end surface of the guide-in end 411. The second guide-in arc surface 4113 connects the guide-in slope 4111 and the lower end surface of the guide-in end 411 and has a small curvature, which is a transition between the guide-in slope 4111 and the lower end surface of the guide-in end 411 and has a reasonable and simple structure.

[0036] Further, the positioning mechanism 4 comprises a second positioning module 42 arranged on the blow conveying section 212, the second positioning module 42 is provided with a second limiting side wall 420, the second limiting side wall 420 extends along the conveying direction of the blow conveying section 212, the transfer seat 1 is provided with a positioning plate 13, the positioning plate 13 is provided with a positioning side wall 131 matched with the second limiting side wall 420, when the transfer mechanism 2 drives the transfer seat 1 to pass through the second positioning module 42, the positioning side wall 131 on the positioning plate 13 tightly abuts against the second limiting side wall 420 on the second positioning module 42. On the basis of the automatic positioning realized by the cooperation of the positioning protrusion 12 and the first positioning module 41, the second positioning module 42 is further arranged to realize secondary positioning by the cooperation of the second limiting side wall 420 on the second positioning module 42 and the positioning side wall 131 on the positioning plate 13, so as to further improve the positioning accuracy.

[0037] Further, the positioning mechanism 4 comprises a third positioning module 43 arranged between the first positioning module 41 and the second positioning module 42, the third positioning module 43 is provided with a third limiting side wall 430, the third limiting side wall 430 cooperates with the positioning side wall 131. When the transfer mechanism 2 drives the transfer seat 1 to pass through the third positioning module 43, the positioning side wall 131 on the positioning plate 13 tightly abuts against the third limiting side wall 430 on the third positioning module 43.

[0038] Further, the heating conveying section 211 and the blow conveying section 212 are straight conveying sections, the positioning conveying section 213 can be a straight conveying section or an arc-shaped conveying section, in the embodiment, the positioning conveying section 213 is an arc-shaped conveying section; accordingly, the first limiting side wall 410 is an arc-shaped surface, the second limiting side wall 420 is a flat surface, the third limiting side wall 430 is provided with an arc-shaped surface at one end close to the first limiting side wall 410, and the third limiting side wall 430 is provided with a flat surface at one end close to the second limiting side wall 420. Since the second limiting side wall 420 and the third limiting side wall 430 cooperate with the positioning plate 13, the second limiting side wall 420 and the third limiting side wall 430 are consistent in height. Since the first limiting side wall 410 cooperates with the positioning protrusion 12, the lower end surface of the first limiting side wall 410 is higher than the upper end surface of the positioning plate 13, so as to avoid the interference between the first limiting side wall 410 and the positioning plate 13.

[0039] Further, the automatic positioning blow molding feeding device of the embodiment further comprises a positioning detection mechanism 5 arranged at the input end of the blow molding conveying section 212. The positioning detection mechanism 5 comprises two infrared sensors which respectively detect the adjacent two conveying seats 1. When the two infrared sensors simultaneously detect the positioning protrusions 12, it indicates that the two conveying seats 1 are positioned correctly. When one of the infrared sensors detects the positioning protrusion 12 and the other infrared sensor does not detect the positioning protrusion 12, it indicates that the latter conveying seat 1 is not positioned correctly. By arranging the positioning detection mechanism 5, the positioning effect can be verified in time, and the positioning abnormality can be found in time, which is beneficial to realize continuous automatic and standardized production.
