Description

Technical Field

[0001] The utility model belongs to the technical field of bag making machine equipment, and particularly relates to a lifting device for bag sealing of a bag making machine. Background Art

[0002] Sealing and cutting bag making machines are widely used in making plastic film packaging bags such as garment bags, socks bags, towel bags, bread bags and jewelry bags. The lifting transmission device is one of the most important structures of the sealing and cutting bag making machine. It can realize the lifting and lowering of the cutting structure or the sealing structure, thereby achieving the purpose of cutting and sealing.

[0003] In the prior art, there is a heat-sealing and cutting device for a plastic bag making machine with a patent announcement number of CN219256626U. When the above patent is in use, the two rubber pressure shafts will separate and descend in the inclined slide groove through the slider as the triangular plate is pressed down. When the rubber pressure shafts press the plastic bag, the rubber pressure shafts that are separated and pressed down from each other will flatten the front and rear ends of the hot air part of the plastic bag, so that the heat-sealing knife will not wrinkle when heat-sealing the plastic bag. However, there are still the following deficiencies in actual use: from a practical point of view, the device only uses a push rod motor to drive the heat-sealing knife to move downward. When sealing the bag, there is a lack of a guide structure, which easily causes the heat-sealing knife to fail to maintain a horizontal state, resulting in different sealing effects on both sides and affecting the sealing quality.

[0004] Therefore, a lifting device for bag sealing of a bag making machine is needed to solve the problem in the prior art that there is a lack of a guide structure, which affects the different bag sealing effects on both sides and affects the quality of the bag sealing. Utility Model Content

DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the embodiments.

[0023] See also Figure 1-4 The utility model provides a lifting device for sealing bags of a bag making machine, comprising a processing table 1, a support column 2, a lifting mechanism 3, a bag sealing mechanism 4 and a cutting mechanism 5. The support column 2 is symmetrically fixedly connected to the top of the processing table 1, a horizontal plate is fixedly connected to the top of the processing table 1, the lifting mechanism 3 is arranged between the support columns 2, the bag sealing mechanism 4 is symmetrically arranged below the lifting mechanism 3, and the cutting mechanism 5 is arranged between the bag sealing mechanisms 4.

[0024] The lifting mechanism 3 is composed of a cylinder 301, a mounting plate 302, a sliding rod 303, a gear 304 and a rack 305. The cylinder 301 is fixedly connected to the top of the horizontal plate, and the output end of the cylinder 301 passes through the horizontal plate. The mounting plate 302 is fixedly connected to the bottom of the output end of the cylinder 301. The middle part of the gear 304 is rotatably connected to a rotating shaft, and the gear 304 is fixedly connected to the left and right sides of the mounting plate 302 through the rotating shaft.

[0025] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth to explain in detail that the sliding rod 303 is symmetrically fixedly connected to the top of the mounting plate 302, and the sliding rod 303 is slidably connected to the cross plate.

[0026] The sliding rod 303 is provided to guide the up and down movement of the mounting plate 302 , thereby increasing the stability of the lifting mechanism 3 .

[0027] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth to explain in detail that the rack 305 is fixedly connected to the inside of the support column 2, and the rack 305 is meshed with the gear 304;

[0028] The gear 304 is meshed and rotated with the rack 305 to ensure that the two ends of the mounting plate 302 are raised and lowered absolutely synchronously, and the mounting plate 302 is kept level.

[0029] According to the above working process, it can be known that: by setting the lifting mechanism 3, the bag sealing mechanism 4 and the cutting mechanism 5 can be stably lifted and lowered, avoiding the imbalance on both sides of the upper heat sealing plate 404, resulting in inconsistent bag sealing effects on both sides, and improving the quality of bag sealing.

[0030] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth specifically explaining that the bag sealing mechanism 4 includes a telescopic rod 401, a connecting block 402, a first spring 403, an upper heat sealing plate 404 and a lower heat sealing plate 405. The telescopic rod 401 is fixedly and symmetrically connected to the bottom of the mounting plate 302, a groove is arranged above the connecting block 402, and the extended end of the telescopic rod 401 is fixedly connected to the inside of the groove. The upper heat sealing plate 404 is arranged on the bottom surface of the telescopic rod 401, and the lower heat sealing plate 405 is arranged above the processing table 1, and the lower heat sealing plate 405 is aligned with the upper heat sealing plate 404 in the upper and lower directions. The first spring 403 is fixedly connected between the connecting block 402 and the bottom surface of the mounting plate 302, and the first spring 403 is sleeved on the outside of the telescopic rod 401;

[0031] Through the elastic effect of the first spring 403, when the upper heat sealing plate 404 contacts the lower heat sealing plate 405, the cushioning of the bag body is increased, thereby improving the stability of the device.

[0032] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth specifically explaining that the cutting mechanism 5 is composed of a fixed block 501, a cutter 502, a positioning column 504, a push-pull plate 505 and a second spring 506. The fixed block 501 is fixedly connected to the lower middle part of the cylinder 301, and a rectangular groove is opened at the bottom of the fixed block 501. The cutter 502 is arranged inside the rectangular groove of the fixed block 501. The positioning column 504 is symmetrically slidably connected to both sides of the fixed block 501. The push-pull plate 505 is fixedly connected to one side of the positioning column 504. The second spring 506 is fixedly connected between the push-pull plate 505 and the fixed block 501.

[0033] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth to explain in detail that positioning grooves 503 are symmetrically opened on both sides of the cutter 502, and the shape of the positioning column 504 is adapted to the positioning groove 503;

[0034] By extending the positioning column 504 into the positioning groove 503, the position of the cutter 502 can be fixed, which makes it convenient for the staff to install the cutter 502 and improves the practicality of the device.

[0035] This scheme has the following working process: the cylinder 301 drives the mounting plate 302 to move downward, and the gears 304 on both sides mesh and rotate with the rack 305 to ensure the horizontality of the two ends of the mounting plate 302. At the same time, the sliding rod 303 is slidably connected with the cross plate to ensure the stability of the mounting plate 302 moving downward, until the upper heat sealing plates 404 on both sides are close to the lower heat sealing plates 405 below, and the bag body in the middle is heat-sealed. At the same time, the bag body is cut by the cutter 502 in the middle to separate the bag body, thereby improving the working efficiency of the device and completing When the cutter 502 needs to be replaced, the push-pull plate 505 is pushed outward to drive the positioning column 504 to disengage from the interior of the positioning groove 503, thereby releasing the fixation of the cutter 502, and the cutter 502 can be disassembled, and then a new cutter 502 is inserted into the interior of the fixing block 501, and the push-pull plate 505 is loosened. Under the elastic action of the second spring 506, the positioning column 504 is driven to reset, so that the positioning column 504 is inserted into the interior of the positioning groove 503, and the cutter 502 is fixed to ensure the stability of the cutter 502.

[0036] In summary: through the setting of the lifting mechanism 3, the bag sealing mechanism 4 and the cutting mechanism 5 can be stably lifted and lowered, avoiding the imbalance between the two sides of the upper heat sealing plate 404, resulting in inconsistent bag sealing effects on both sides, and improving the quality of bag sealing; through the setting of the cutting mechanism 5, the staff can disassemble the cutter 502, which is convenient for replacing a new cutter 502 and disassembling and assembling the cutter 502, thereby ensuring the cutting effect of the device and improving the practicality of the device.
