Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Referring to fig. 1-3, a weight lifting safety testing device for a plastic packaging bag comprises a base plate 1, wherein supporting legs 21 are fixedly mounted at the bottom corners of the base plate 1 and used for supporting an integrated device, a lifting mechanism 2 is fixedly mounted at the left side of the base plate 1, a supporting rod 3 is mounted on the lifting mechanism 2, the lifting mechanism 2 can drive the supporting rod 3 to move up and down, in this embodiment, the lifting mechanism 2 is implemented by a motor 16 and a lead screw 17, namely, the integrated lifting mechanism 2 comprises a mounting sleeve 14 fixed at the left side of the base plate 1, the mounting sleeve 14 is hollow, a strip-shaped hole 15 is formed in the right side of the mounting sleeve 14, the motor 16 is fixedly mounted at the bottom of the mounting sleeve 14, the lead screw 17 is fixedly mounted at the output end of the motor 16, the top of the lead screw 17 is mounted at the top of the mounting sleeve 14 through a bearing, a first thread bushing 18 is in threaded connection with the outer wall of the lead screw 17, the first thread bushing 18 is fixed with the supporting rod 3, and the supporting rod 3 is located inside the strip-shaped hole 15.

Through the technical scheme, the motor 16 can be started when the up-and-down movement of the support rod 3 is realized, the motor 16 drives the screw rod 17 to rotate in the mounting sleeve 14, the first threaded sleeve 18 on the outer wall of the screw rod 17 and the support rod 3 are driven to move up and down in the strip-shaped hole 15, and the up-and-down reciprocating movement of the support rod 3 is realized through the forward and reverse rotation of the motor 16.

It is further supplemented that, because the length that the bracing piece 3 stretches out is longer, and the pulling force that current wrapping bag generally bore is also generally great, in order to guarantee that bracing piece 3 has sufficient holding power when supporting, install second thread bush 19 on lead screw 17 in proper order, and fixed mounting has stiffener 20 on the outer wall of second thread bush 19, stiffener 20 is located bar hole 15 equally, and the top of stiffener 20 is fixed in the bottom of bracing piece 3, consequently stiffener 20 also can move along with the removal of bracing piece 3 when bracing piece 3 reciprocates, stiffener 20 can increase the holding power to bracing piece 3 simultaneously, avoid the production of above-mentioned condition as far as possible.

And there are tensiometer 4 at the bottom fixed mounting of bracing piece 3, the bottom fixed mounting of tensiometer 4 has dead lever 5, and the bottom both sides of dead lever 5 then the symmetry install couple 6, couple 6 is used for hanging the handle part of wrapping bag, and be provided with the slide rail 7 that two symmetries set up in the bottom of couple 6, and slide rail 7 is then fixed on bottom plate 1, and the equal slidable mounting in inside of every slide rail 7 has two sliders 8, install first grip block 9 and second grip block 10 on two sliders 8 of homonymy, and all be provided with first step 11 and second step 12 on the one side that is close to of first grip block 9 and second grip block 10, the equal threaded connection in inside of two sliders 8 of homonymy has two-way screw 13 simultaneously, two sliders 8 of homonymy mutually support with two screw on the two-way screw 13 respectively, and fixed mounting has the knob 22 that makes things convenient for rotatory two-way screw 13 at the both ends of two-way screw 13.

Through the technical scheme, the hook 6 is used for hanging a handle part of a test package, the bottom of the package bag is clamped and fixed through the first clamping plate 9 and the second clamping plate 10, concretely, the bottom of the package bag is placed between the first clamping plate 9 and the second clamping plate 10, then the rotary knob 22 drives the bidirectional screw 13 to rotate in the slider 8, the slider 8 is driven to be close to or away from each other in the slide rail 7, when the two parts are close to each other, the bottom of the package bag is clamped in the first step 11 and the second step 12, so that the bottom of the package bag is fixed, after the fixing, the lifting mechanism 2 drives the support rod 3 and the tension meter 4 at the bottom of the support rod 3 to move upwards, the package bag is gradually stretched, along with the ascending height change, the package bag is gradually tightened and deformed, the tension meter 4 at the top can display the tension in real time until the fracture position of the package bag, the maximum value of the lifting force of the package bag is known, and the safety test of the package bag is realized.

And through the fixed of first step 11 and second step 12 for the wrapping bag can increase in the centre gripping and the area of contact between first grip block 9 and the second grip block 10, thereby improve the centre gripping effect to the wrapping bag, and to the wrapping bag in the centre gripping, the bottom of wrapping bag is the extrusion of bending form in two grip blocks, and then is difficult for droing when fixed, fixes more firmly.

Furthermore, rubber pads can be bonded on the inner walls of the first step 11 and the second step 12, so that friction force between the first step and the second step can be increased, and firmness in fixing is further improved.

When the lifting device is used, the top of the packaging bag is hung on the two hooks 6, the bottom of the packaging bag is fixed through the first clamping plate 9 and the second clamping plate 10, the packaging bag is lifted by controlling the lifting mechanism 2 to move upwards, and meanwhile, the tension meter 4 measures the tension.
