[0026] See also Figures 1 to 3 The present application provides a curved surface indexing cam module 100, which includes a bracket 10, an input shaft assembly 20 and an output shaft assembly 30. The bracket 10 includes a top wall 11 and two side walls 12. The two side walls 12 are respectively connected to the two ends of the top wall 11 and are surrounded by the top wall 11 to form a working chamber 13, and an opening 14 is formed on the opposite sides of the working chamber 13; the two ends of the input shaft assembly 20 are respectively movably connected to the two side walls 12, and the output shaft assembly 30 is rotatably installed on the top wall 11, and extends into the working chamber 13 to cooperate with the input shaft assembly 20 for transmission.

[0027] It can be understood that by connecting the two side walls 12 to the two ends of the top wall 11 respectively and forming a working chamber 13 between the two side walls 12 and the top wall 11, and forming an opening 14 on the opposite sides of the working chamber 13, not only the structure of the bracket 10 is simple and the weight is lighter, but also the openings 14 on both sides of the working chamber 13 allow air to flow through the working chamber 13 and take away the heat generated by the input shaft assembly 20 and the output shaft assembly 30 working in the working chamber 13, thereby helping to improve the heat dissipation efficiency of the input shaft assembly 20 and the output shaft assembly 30.

[0028] Optionally, in one embodiment, if Figure 1 As shown, each side wall 12 includes a support portion 121 and a mounting portion 122. Along the axial direction of the output shaft assembly 30, the support portion 121 is located above the mounting portion 122 and connected to the top wall 11. The mounting portion 122 is used to mount the input shaft assembly 20. The width of the support portion 121 is greater than the width of the mounting portion 122, and a gap 123 is formed between the support portion 121 and the mounting portion 122. In this way, it is beneficial to further reduce the weight of the bracket 10, thereby reducing the weight of the arc surface indexing cam module 100. Optionally, one side edge of the support portion 121 is flush with one side edge of the mounting portion 122, and the other side edge of the support portion 121 and the other side edge of the mounting portion 122 are arranged at an obtuse angle.

[0029] Optionally, in one embodiment, if Figure 2 and Figure 3 As shown, the bracket 10 further includes a bottom wall 15, which is arranged opposite to the top wall 11, and the two ends of the bottom wall 15 are respectively connected to the two side walls 12; and the bottom wall 15 is provided with an oil receiving groove 151 arranged toward the working chamber 13. The oil receiving groove 151 can be used to store lubricating oil. The bottom wall 15 can form a support between the two side walls 12, thereby improving the structural strength of the bracket 10.

[0030] The input shaft assembly 20 includes an input shaft 21 and a cambered indexing cam 22 fixedly sleeved on the outer circumference of the input shaft 21. The output shaft assembly 30 includes an output shaft 31 and a plurality of cam follower bearings 32. A dividing plate 35 is provided at one end of the output shaft 31. The plurality of cam follower bearings 32 are mounted on the dividing plate 35 and are distributed at intervals along the circumference of the dividing plate 35. The plurality of cam follower bearings 32 are meshed with the cambered indexing cam 22. The dividing plate 35 and the output shaft 31 are an integral structure.

[0031] Specifically, Figure 2 As shown, one end of the arc surface indexing cam 22 stops at the shoulder of the input shaft 21, and the other end is locked by a locking nut, so that the arc surface indexing cam 22 and the input shaft 21 are fixed along the axial direction. The arc surface indexing cam 22 and the input shaft 21 are fixed by a square pin. Among them, the locking nut can be configured as a round nut with a back-stop washer.

[0032] The arc surface indexing cam module 100 further includes two eccentric nut sleeves 50, the two ends of the input shaft 21 are respectively connected to the inner peripheral walls of the two eccentric nut sleeves 50, and the outer peripheral walls of the two eccentric nut sleeves 50 are respectively rotatably mounted on the two side walls 12; wherein, as the two eccentric nut sleeves 50 rotate relative to the side walls 12, the axial center distance between the input shaft 21 and the output shaft 31 increases or decreases. In this way, the axial center distance between the input shaft 21 and the output shaft 31 is adjusted simply.

[0033] The input shaft assembly 20 further includes a deep groove ball bearing 24, which is installed between the input shaft 21 and one of the eccentric nut sleeves 50, and the two ends of the deep groove ball bearing 24 along its own axial direction are respectively used to stop and cooperate with the input shaft 21 and the eccentric nut sleeve 50. The deep groove ball bearing 24 can not only improve the rotation stability of the input shaft 21, but also limit the relative movement of the input shaft 21 along its own axial direction and the eccentric nut sleeve 50 by respectively stopping and cooperating with the input shaft 21 and the eccentric nut sleeve 50 at the two ends of the deep groove ball bearing 24 along its own axial direction.

[0034] like Figure 2 As shown, the arc surface indexing cam module 100 further includes two eccentric nuts 60, and the input shaft assembly 20 further includes two first tapered roller bearings 25, each of which is correspondingly installed between the input shaft 21 and an eccentric nut sleeve 50; each corresponding thread is connected to an eccentric nut sleeve 50, and is used to cooperate with the input shaft 21 to clamp a corresponding first tapered roller bearing 25. Specifically, by screwing the eccentric nut 60 relative to the eccentric nut sleeve 50, the eccentric nut 60 moves along the axial direction of the input shaft 21, thereby realizing pre-compression of the first tapered roller bearing 25.

[0035] like Figure 1 and Figure 3 As shown, the arc surface indexing cam module 100 also includes a mounting seat 40, a mounting hole 111 is opened on the top wall 11, one end of the mounting seat 40 is fixedly connected to the mounting hole 111, and the other end extends toward the working chamber 13, and the output shaft 31 is rotatably mounted on the mounting seat 40. The mounting seat 40 is used to support the output shaft 31 to prevent the output shaft 31 from deflecting.

[0036] The output shaft assembly 30 also includes two second tapered roller bearings 33 and two fastening nuts 34. Each second tapered roller bearing 33 is respectively installed between the output shaft 31 and the mounting seat 40. Each fastening nut 34 is correspondingly threadedly connected to the output shaft 31 and is used to cooperate with the mounting seat 40 to clamp a corresponding second tapered roller bearing 33.

[0037] Specifically, Figure 3 As shown, a mounting groove 41 is respectively formed at both ends of the mounting seat 40, and each second tapered roller bearing 33 is correspondingly mounted in one mounting groove 41, and one end of each second tapered roller bearing 33 abuts against the bottom wall of the mounting groove 41, and the other end is locked by a fastening nut 34. The fastening nut 34 can be configured as a round nut with a stop washer.

[0038] Furthermore, a washer 36 may be provided between the fastening nut 34 and the second tapered roller bearing 33. The arc surface indexing cam module 100 further includes an oil seal 70, the inner ring of the oil seal 70 is sealed with the washer 36, and the outer ring of the oil seal 70 is sealed with the mounting seat 40 to prevent the lubricating oil from leaking during the rotation of the output shaft 31.

[0039] The present application also provides a paper cup machine, which includes the arc surface indexing cam module 100 described in any one of the above embodiments.

[0040] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
