Abstract
The utility model relates to a pneumatic type cover screwing device. Both sides of a cover screwing device body similar to a cuboid are respectively provided with a clamp claw, compressed air is utilized to push the clamp claw to hold the cover of a bottle, a reset tension spring is used for reset, the lower end of the cover screwing device is provided with a friction plate so as to make up the defect of insufficient holding force of the clamp claw on the cover of the bottle and eliminate the phenomenon that the clamp claw and the cover of the bottle slip. The utility model has the advantages of simple structure and long service life.
Description
Technical field
The utility model relates to a kind of pneumatic type cap screwing device, belongs to packing machinery technology.
Background technology
Relevant by retrieval patent documentation does not have the cap screwing device identical with the utility model.
As everyone knows, a variety of containers and lid adopt screw thread fit.Various lid tighteners are used for bottling product line, and cap screwing device is the critical component of lid tightener, and its function is the clamping lid and is rotated down, lid is tightened on the container.At present, the cap screwing device of widespread usage all adopts mechanical drive mode.Its structure more complicated heaviness, manufacture difficulty is big, and cost is higher, and lacks flexibility, damages bottle cap sometimes.
The utility model patent applicant once designed a kind of pneumatic type cap screwing device and was used for reality, this cap screwing device has the screw capping body of an approximate cuboid, screw capping body upper end is connected with the transmission shaft of a hollow, the hole of a horizontal direction is arranged at screw capping body top, two valve pistons are housed in the hole, a claw respectively is equipped with in screw capping body both sides, and claw can rotate around the bearing pin at its middle part, and claw upper end portion contacts with two valve piston outside end faces respectively.When pressurized air was from the lateral aperture of transmission shaft importing screw capping body, two valve pistons moved laterally, and then promote the claw head, so claw rotates around bearing pin, the lateral movement inwards of the lower end of claw clamps bottle cap.At this moment, transmission shaft is rotated down under the driving of other parts of lid tightener, tightens bottle cap.When pressurized air was discharged, a compression spring of screw capping body lower end was pushed the lower end of claw open to both sides, so claw and bottle cap break away from, valve piston also sets back.
This existing pneumatic type cap screwing device has overcome the shortcoming of aforesaid mechanical type cap screwing device, but itself has two shortcomings, and the first is when the screw capping moment of torsion is big, and claw is not enough to the lid Clamping force, and skidding between claw and the bottle cap takes place easily.Its two because the restriction of installing space, the compression spring size that resets is less, its stressed ultimate limit state that is in, thereby the service life of this spring is short.Because above-mentioned two shortcomings are a greater impact the functional reliability of this pneumatic cap screwing device and widespread popularity.
The utility model content
The purpose of this utility model is that a kind of later-model pneumatic type cap screwing device will be provided, and to overcome the above-mentioned shortcoming of existing pneumatic cap screwing device, makes its more extensive reality that is used for reliably.
The purpose of this utility model is achieved in that it includes: transmission shaft, screw capping body, piston, claw, bearing pin, reset tension spring installation sheet, reset tension spring and friction shim etc., it is characterized in that: respectively there is a claw both sides at the screw capping body of an approximate cuboid, respectively there is a reset tension spring installation sheet in each head outside, claw upper end, between two reset tension spring installation sheets, two reset tension springs are installed, a friction shim also is housed in the cap screwing device lower surface.
Structure of the present utility model has been compared two place's important improvement with existing pneumatic type cap screwing device, one, increased friction shim in the cap screwing device lower end, this friction shim is made by the material that has great friction coefficient between rubber or other and bottle cap, produced static friction force between this friction shim and the bottle cap upper surface during screw capping, remedy claw to bottle cap Clamping force defect of insufficient, eliminated the phenomenon that claw and bottle cap skid.Its two, be two extension springs that the reseting pressuring spring that will place the cap screwing device lower end originally places the claw upper end instead, like this, each spring stress reduces half, and installing space is bigger, the spring size can strengthen, spring greatly prolongs service life.
In sum, the utility model pneumatic type cap screwing device has overcome the above-mentioned shortcoming of existing pneumatic type cap screwing device effectively, can more extensively be used for reality reliably.
Description of drawings
Fig. 1 is the main cutaway view of an embodiment of the utility model pneumatic type cap screwing device, as the structural representation of this embodiment.
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described in detail:
Referring to Fig. 1, introduce the structure of the utility model pneumatic type cap screwing device and form.Among the figure: the 1st, transmission shaft, the 2nd, screw capping body, the 3rd, piston, the 4th, piston packing ring, the 5th, claw, the 6th, claw bearing pin, the 7th, reset tension spring, the 8th, reset tension spring installation sheet, the 9th, friction shim, the 10th, bottle cap, the 11st, container.
As seen from Figure 1, the hole of horizontal direction is arranged on the top of screw capping body 2, two valve pistons 3 are housed in the hole.When pressurized air enters the lateral aperture middle part by transmission shaft 1, promoting two valve pistons moves laterally, thereby promoting claw 5 upper ends moves laterally, claw lower end lateral movement inwards clamps bottle cap 10, this moment, transmission shaft 1 was rotated down under other parts of lid tightener drive, so produce static friction force between friction shim 9 and the bottle cap upper surface, the existence of this static friction force has just remedied the deficiency of claw to the bottle cap Clamping force.
Referring to Fig. 2, introduce the mounting means of reset tension spring in the utility model pneumatic type cap screwing device.From overlooking direction, respectively there is a reset tension spring installation sheet 8 in the head outside, upper end of two claws 5, two reset tension springs 7 are housed between two installation sheets, and after bottle cap was tightened, pressurized air was discharged, under the reset tension spring effect, the lateral movement inwards of claw upper end head pushes back original position with piston, and open the claw lower end simultaneously, break away from bottle cap, finished the screw capping working cycle like this one time.
