Description

Technical Field

[0001] The utility model belongs to the field of printing machinery, and in particular relates to a paper feed head hanging mechanism in a paper feeder (feeder). Background Art

[0002] The paper feeder is a commonly used feeding part of sheet-fed printing and packaging equipment (such as offset printing machines, laminating machines, etc.). Its function is to accurately separate the top sheet of paper from the paper pile and transport it to the next station. The height of the paper feeder of some equipment is relatively low due to the main machine of the equipment. If this type of paper feeder still uses the traditional longitudinal suspension mechanism, the operator will bend or squat when operating the paper feeder, and there is a risk of hitting the head. Therefore, the market urgently needs to solve the problem of inconvenient operation and lack of safety of low-height paper feeders. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a paper feeding head suspension mechanism, which adopts the following technical solutions:

[0004] The paper feed head suspension mechanism includes a frame, with a support block on each side of the frame, and linear guide rails are fixedly connected to the support blocks on both sides. The linear guide rails on both sides cooperate with their corresponding linear bearings, and the linear bearings on both sides are fixedly connected to the connecting plates on both sides. The connecting plates on both sides are connected by fixed pillars, and a square seat is provided in the middle position of the fixed pillar. The square seat is provided with a through hole for the guide rail to slide, and a shaft sleeve is installed in the through hole to cooperate with the guide rail so that the guide rail can slide therein. One end of the guide rail is fixedly connected to the paper feed head mechanism, and an up and down driving device is provided on the square seat for driving the guide rail to slide on the square seat, thereby driving the paper feed head mechanism to move up and down.

[0005] Furthermore, a locking mechanism is provided on each side of the frame, and the two locking mechanisms are symmetrically arranged and connected in the middle by a fixed pillar. The fixed pillar can be composed of a round support and a square support. The round support and the square support are arranged in parallel, and there can be one or more than one; the locking mechanism includes a universal handle, a locking block, a locking shaft, a limit block, a first closing plate, and a second closing plate. The connecting plate includes a side plate and a bottom plate. The side plate of the connecting plate is fixedly connected to the limit block. The locking block is fixed to the bottom plate of the connecting plate and is arranged in the middle of the limit block. One end of the locking block is threadedly connected to the universal handle, and the locking block cooperates with the locking shaft. The locking shaft, the first closing plate, the second closing plate, and the support are fixed to form a whole by screws.

[0006] Furthermore, the up and down driving device includes a handwheel, a screw rod, and an adjustment plate, the handwheel is connected to one end of the screw rod, the adjustment plate is fixedly connected to the guide rail, and the screw rod is connected to the adjustment plate through a thread.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] By setting fixed pillars and connecting plates, linear bearings, and linear guide structures in the paper feeder head suspension mechanism, and adopting an up and down adjustment structure of an adjustment plate, a hand wheel, and a lead screw, the paper feeder head mechanism can be adjusted up and down, front and back, and at the same time, the locking mechanism is used to ensure stability during adjustment. Ultimately, the operator of the low-height paper feeder suspension no longer needs to bend over or hit his head, which is more ergonomic, convenient, and safe. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figure 1-Figure 4 As shown, a paper feed head suspension mechanism has two inner sides of the frame, each of which is provided with a support. The left side of the figure is an operating side support 1, and the right side is a transmission side support 2. The operating side support 1 and the transmission side support 2 are both fixed to the paper feeder wall plate 21 by screws, which strengthens the rigidity of the transmission side wall plate and the transmission side wall plate of the paper feeder. The two parts of the mechanism on both sides of the frame are symmetrically arranged. The following is only an introduction to the mechanism on the right transmission side. The transmission side support 2 is fixedly connected to a linear guide rail 8 by screws. The linear guide rail 8 and the linear bearing 10 are used in conjunction. The linear bearing 10 is fixed to the bottom plate of the connecting plate 5. The side plate of the connecting plate 5 is connected to one end of the round support 4 and the square support 5 by screws, and the other end is connected to the connecting plate on the left operating side. The sliding between the linear bearing 10 and the linear guide rail 8 drives the connecting plate 5 to realize the forward and backward movement of the paper feed head mechanism 20. The round support 4 and the square support 5 are arranged in parallel, and a square seat 18 is provided in the middle position of the two. The square seat 18 is provided with two through holes, and is connected with two guide rails 17 through the standard part GB12613.1 rolled shaft sleeve to achieve relative sliding. An adjustment plate 16 is provided above the square seat 18, and the adjustment plate 16 is fixedly connected to one end of the guide rail 17. The middle position of the adjustment plate 16 is connected to the screw rod 15 through a thread, and the screw rod 15 is fixed to the hand wheel 14 through a pin shaft. The other end of the guide rail 17 is connected to the paper feeding head mechanism through the paper feeding head connecting plate 19. When in use, the hand wheel 14 can be adjusted to drive the screw rod 15, so as to realize the up and down adjustment of the paper feeding head mechanism 20.

[0018] A locking mechanism is symmetrically provided on both sides of the paper feed head suspension mechanism. The mechanism on the right transmission side is also introduced below. The locking mechanism includes a universal handle 6, a locking block 7, a locking shaft 9, a limit block 11, a first closing plate 12, and a second closing plate 13. A limit block 11 is installed on the side plate of the connecting plate 5. The middle part of the limit block 11 is a through channel, in which a locking block 7 is provided. The locking block 7 is installed on the bottom plate of the connecting plate 5. One end of the locking block 7 is connected to the universal handle 6 by a threaded connection, and the locking block 7 cooperates with the locking shaft 9. The locking shaft 9, the first closing plate 12, the second closing plate 13, and the transmission side support 2 are fixed together by screws to form a whole. The locking and loosening between the locking block 7 and the locking shaft 9 are realized through the threaded connection between the universal handle 6 and the locking block 7. The mutual limitation between the limit block 11 and the locking block 7 realizes the locking of the entire mechanism at each required position during the relative sliding process.
