Punched card equipment
Technical field
The utility model belongs to and relates to a kind of punched card equipment.
Background technology
Punched card equipment is the common equipment in food filling field.Existing punched card equipment is when checking card, because the packaging bag many places of filling material are in the fold state, planeness and the tightness of checking card like this descend greatly.
The utility model content
At the defective that exists in the prior art and deficiency, it is a kind of when checking card that the utility model embodiment provides, and guarantees the punched card equipment of packaging bag planeness.
In order to achieve the above object, the utility model proposes a kind of punched card equipment, comprise pedestal, described pedestal is provided with punch-card device, described punch-card device one side is provided with stretching device, and described stretching device comprises draft cylinder, and described draft cylinder connects fixing device, it is laterally mobile that described draft cylinder can drive fixing device, and described fixing device can clamp the packaging bag of filling material.
Preferential as technique scheme, described fixing device comprises clamp fitting head and clamping movable head on the other side, described clamp fitting head with clamp the interval of leaving the clamping packaging bag between the movable head.
Technique scheme is preferential on the work, and described control setup comprises the stretching handle, and described stretching handle connects connecting rod, when described stretching handle presses down, and described fixing device retraction; When described connecting rod clamping stroke switch, fixing device stops action.
Preferential as technique scheme is provided with pintle hook lock mechanism between described stretching handle and the connecting rod.
The utility model proposes a kind of punched card equipment, comprise pedestal, described pedestal is provided with punch-card device, described punch-card device one side is provided with stretching device, described stretching device comprises draft cylinder, described draft cylinder connects fixing device, and it is laterally mobile that described draft cylinder can drive fixing device, and described fixing device can clamp the packaging bag of filling material; Also comprise control setup, described control setup connects draft cylinder, and it is flexible that described control setup can be controlled described draft cylinder so that described fixing device approach/away from the place that checks card of punch-card device.Like this, punched card equipment is finished packaging bag by draft cylinder and fixing device and is stretched when checking card, the planeness at the position that effectively guaranteed to check card.
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.For the person of ordinary skill in the field, to the detailed description of the present utility model, described and other purposes of the present utility model, feature and advantage will be apparent.
Description of drawings
Fig. 1 is preferred embodiment structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the right elevation of Fig. 1;
Fig. 4 is the birds-eye view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The utility model proposes a kind of punched card equipment, as Fig. 1, Fig. 2, shown in Figure 3, comprise pedestal 1, described pedestal 1 is provided with punch-card device, described punch-card device one side is provided with stretching device, and described stretching device comprises draft cylinder 4, and described draft cylinder 4 connects fixing device 13, it is laterally mobile that described draft cylinder 3 can drive fixing device 13, and described fixing device 13 can clamp the packaging bag of filling material;
By the pressure of rotation air pressure adjustment button 8 adjustable cylinder, the size of pressure can be read respectively on compression indicator 2.
Also comprise control setup, described control setup connects draft cylinder 4, and it is flexible that described control setup can be controlled described draft cylinder 4 so that described fixing device 13 approach/away from the place that checks card of punch-card device.
Described fixing device 13 comprises clamp fitting head 5 and clamping movable head 6 on the other side, leaves the interval that clamps packaging bag between described clamp fitting head 5 and the clamping movable head 6.
Described control setup comprises stretching handle 9, and described stretching handle 9 connects connecting rod 12, when described stretching handle 9 presses down, and described fixing device 13 retractions; When described connecting rod 12 clamping stroke switches 11, fixing device stops action, is provided with pintle hook lock mechanism 15 between described stretching handle 9 and the connecting rod 12.。
During work, the packaging bag of sealing of will checking card has an end of material to be placed on a side of baffle plate 7, the other end is put into the clamp fitting head 5 of clamping structure 13 and is clamped between the movable head 6, to clamp movable head 6 is wrenched to clamp fitting head 5, with stretching handle 9 to pressing down, draft cylinder 4 withdrawal piston rods, drive clamping structure 13 away from the place that checks card, pintle hook lock mechanism 15 is locked with buckle downwards simultaneously, when connecting rod 12 clamping stroke switches 11, draft cylinder 4 stops action, depresses the handle 10 of checking card, and punch-card device 3 is checked card downwards.Lift stretching handle 9, draft cylinder 4 stretches out, and clamping mechanism 13 unclamps to reload and carries out next cycling, and the extension elongation of punch-card device 3 can adjust to reach optimum efficiency by adjusting mechanism 14.
Certainly; the utility model also can have other embodiment; under the situation that does not deviate from the utility model spirit and essence thereof; the person of ordinary skill in the field works as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of claim of the present utility model.
