The cam transmission mechanism comprises a fourth cam rail (2) and a fifth cam rail (3) which are sleeved on a center shaft (1), and further comprises a fourth roller follower (4), a fifth roller follower (5), a rotating shaft (6), a gear (7), a rack (8) and a support (9), wherein the gear (7) meshes with the rack (8), the fourth cam rail (2) is connected with the fourth roller follower (4) through a cam pair, the fifth cam rail (3) is connected with the fifth roller follower (5) through a cam pair, a fourth roller wheel (4-1) is arranged on the upper portion of a stay bar (4-2), the lower portion of the stay bar (4-2) is arranged on the support (9), a stay bar resetter (10) is further mounted on the lower portion of the support frame (9), and the fifth roller follower (5) is connected with the gear (7) through the rotating shaft (6). The cam transmission mechanism is simple in structure, low in cost and excellent in transmission effect, and realizes precision transmission.

Description

Cam drive

Technical field

The utility model relates to a kind of package packing machine, particularly a kind of cam drive that is used for Cover whirling Machine or filling machine.

Background technique

At present, in industries such as daily use chemicals, food, medicine, the spiral cover driving mechanism of filling machine or Cover whirling Machine is the important component part of filling machine or Cover whirling Machine, by the spiral cover driving mechanism power is transmitted, be beneficial to the finishing of relevant action of spiral cover parts on filling machine or the Cover whirling Machine, handle the spiral cover parts at the accurate bottle cap on the aligning spiral cover operation position on height and the distance.The existing spiral cover driving mechanism that is used for filling machine or Cover whirling Machine generally adopts pneumatic or the Electric actuator structure realizes, spiral cover driving mechanism complex structure, cost height, and finishing of pneumatic or the wayward trickle action of Electric actuator structure, transmission precision is poor, and the transmission effect is undesirable.

The model utility content

The purpose of model utility is the deficiency that exists in the above-mentioned technology, provide a kind of simple in structure, cost is low, transmission is effective, can realize the cam drive that is used for filling machine or Cover whirling Machine of precision drive.

Realize that the above-mentioned purpose technological scheme is: a kind of cam drive, include No. four cam rails and No. five cam rails of being sleeved on the axis, also include roller follower No. four, No. five roller followers, rotating shaft, gear, tooth bar and supporting frame, No. four roller followers include No. four rollers and strut, No. five roller followers include No. five rollers and swing arm, No. four cam rail is connected by the cam parafacies with No. four roller followers, No. five cam rail is connected by the cam parafacies with No. five roller followers, No. four roller is arranged on strut top, the strut bottom is arranged on the supporting frame, the strut resetter also is equipped with in the strut bottom, No. five roller follower is connected with gear by rotating shaft, and gear is meshed with tooth bar on being arranged on supporting frame.

Further, described strut resetter is a spring.

Further, described No. five rollers are arranged on an end of swing arm, and the swing arm the other end is connected with rotating shaft top, and gear is arranged on the rotating shaft bottom.

After adopting technique scheme, have a lot of benefits: the utility model is simple in structure, cost is low, and No. four cam rails of the present utility model are connected by the cam parafacies with No. four roller followers, and No. five cam rail is connected by the cam parafacies with No. five roller followers, wheel and rack is meshed, the structure that the utility model adopts can be controlled finishing of trickle action, the transmission precision height, transmission is effective, has realized precision drive.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

Embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

Embodiment

As shown in drawings, a kind of cam drive, include suit and be fixed on No. four cam rails 2 and No. five cam rails 3 on the axis 1, also include roller follower 4 No. four, No. five roller followers 5, rotating shaft 6, gear 7, tooth bar 8 and supporting frame 9, No. four roller followers 4 include No. four roller 4-1 and strut 4-2, No. five roller followers 5 include No. five roller 5-1 and swing arm 5-2, No. four cam rail 2 is connected by the cam parafacies with No. four roller followers 4, No. four roller 4-1 contacts with the lower end surface of No. four cam rails 2, and can on the lower end surface of No. four cam rails 2, roll, No. five cam rail 3 is connected by the cam parafacies with No. five roller followers 5, No. five roller 5-1 contacts with the outer peripheral surface of No. five cam rails 3, and can on the outer peripheral surface of No. five cam rails 3, roll, No. four roller 4-1 is arranged on strut 4-2 top, No. four roller 4-1 is connected with strut 4-2 top by bearing pin 4-3, strut 4-2 bottom is arranged on the supporting frame 9, strut resetter 10 springs also are equipped with in strut 9 bottoms, strut 9 can be under the effect of strut resetter 10, keep No. four roller 4-1 to contact with the lower end surface of No. four cam rails 2, No. five roller follower 5 is connected with gear 7 by rotating shaft 6, No. five roller 5-1 fixed cover dresses are arranged on the end of swing arm 5-2, the swing arm 5-2 the other end is connected with rotating shaft 6 tops, gear 7 fixed covers dresses is arranged on rotating shaft 6 bottoms, and gear 7 is meshed with tooth bar 8 on being fixedly installed on supporting frame 9.

Working principle of the present utility model is: No. four cam rails 2 and No. five cam rails 3 that suit is fixed on the axis 1 maintain static, and remain static.No. four cam rails 2 are connected the generation relative movement with No. four roller followers 4 by the cam parafacies, thereby make No. four roller followers 4 produce axial motions; No. five cam rails 3 are connected the generation relative movement with No. five roller followers 5 by the cam parafacies, thereby make rotating shaft 6 that the rotation of several angle be arranged, and the rotation of rotating shaft 6 makes gear 7 be meshed with tooth bar 8 and produces motion, makes tooth bar 8 produce radial motions.By the synthetic motion of the cooperation of two pairs of cam pairs, make the utility model can handle the bottle cap of spiral cover parts on accurate aligning spiral cover operation position on height and the distance of filling machine or Cover whirling Machine, help spiral cover.

The utility model is not limited to the foregoing description, and the technological scheme that all employings are equal to replacement or equivalence replacement formation all belongs to the claimed scope of the utility model.
