Description

[Technical field]

[0001] The invention relates to the technical field of vest bag production, and in particular to a vest bag production device and method which are convenient for adapting to different specifications. [Background technology]

[0002] A vest bag is a packaging bag that is usually used to package and protect items to prevent leakage and contamination. The vest bag is usually made of high-density plastic material with excellent leak-proof performance and load-bearing capacity.

[0003] The vest bag production device usually includes a hot needle mechanism, a film-beating mechanism and a cutting and heat-sealing mechanism, wherein the film-beating mechanism is arranged between the hot needle mechanism and the cutting and heat-sealing mechanism, and the film-beating mechanism usually adopts a transmission chain to drive a rapping rod for transmission. During operation, after the vest bag is delivered to the right place, the hot needle mechanism will pass through the position to be hot-joined of the vest bag; then the cutting and heat-sealing mechanism will be used to cut and heat-seal the vest bag; then the film-beating mechanism will be used to beat the cut end of the vest bag downwards, so that the cut end of the vest bag leaves the cutting and heat-sealing mechanism; finally, after the required number of vest bags are stacked, the hot needle mechanism will heat the position to be hot-joined, so as to realize the hot-joining of the whole stack of vest bags together. The structure of the vest bag 100' is as follows Figure 1 As shown, in Figure 1 Where W represents the width of the vest bag 100', L represents the height of the vest bag 100', and A represents the distance between the cut and the hot-welding position of the vest bag 100'. However, the existing vest bag production device has the following defects in actual use:

[0004] 1. The distance between the hot needle mechanism and the cutting and heat sealing mechanism is fixed, that is, the distance A between the incision of the vest bag and the hot-sealing position is fixed, which cannot meet the production needs of vest bags of various specifications. Instead, corresponding production devices need to be purchased for each specification of vest bags, which has poor flexibility and high cost.

[0005] 2. The film-beating mechanism uses a transmission chain to drive a beater rod for transmission. The entire film-beating mechanism occupies a large space, so that the minimum distance A between the incision of the vest bag and the ironing position is 80 mm, which cannot increase the use capacity of the vest bag.

[0006] In view of the above-mentioned problems, the inventor of this case conducted in-depth research on the issue, which led to the creation of this case. [Summary of the invention]

[0007] The technical problem to be solved by the present invention is to provide a vest bag production device and method that are easy to adapt to different specifications, so as to solve the problem that the existing vest bag production device cannot meet the production needs of vest bags of various specifications and cannot improve the use capacity of the vest bags.

[0008] The present invention is achieved in that:

[0009] In a first aspect, a vest bag production device that is easy to adapt to different specifications includes a frame, a cutting and heat-sealing mechanism, a hot needle mechanism, a film-beating plate mechanism, and a hot needle adjustment mechanism; the cutting and heat-sealing mechanism, the film-beating plate mechanism, and the hot needle mechanism are sequentially arranged on the frame along the production direction;

[0010] The hot needle adjustment mechanism includes a supporting swing plate, a movable supporting plate, a first linear sliding assembly, an adjusting screw and a screw driving assembly; supporting swing plates are provided on the frame at positions corresponding to the two ends of the hot needle mechanism, and the upper part of each supporting swing plate is slidably connected to a movable supporting plate through a first linear sliding assembly, and the hot needle mechanism is connected between the two movable supporting plates; the screw driving assembly is connected to the supporting swing plate, and the adjusting screw is extended along the production direction, and the adjusting screw is threadedly connected to the movable supporting plate, and one end of the adjusting screw is connected to the screw driving assembly, and the screw driving assembly drives the adjusting screw to drive the movable supporting plate and the hot needle mechanism to move and adjust along the production direction.

[0011] In a second aspect, a production method for a vest bag production device that is easy to adapt to different specifications, the production method comprises the following steps:

[0012] Step S1, determining the distance between the incision and the hot-stitching position of the vest bag according to the specifications of the vest bag to be produced, and using the hot-stitching needle adjustment mechanism to drive the hot-stitching needle mechanism to adjust the position according to the distance between the incision and the hot-stitching position;

[0013] Step S2, during the production process, the hot needle of the hot needle mechanism is controlled to extend upward, and when the vest bag is delivered to the right position, the pressing plate of the hot needle mechanism is controlled to descend to press the vest bag tightly and make the hot needle pass through the hot connection position of the vest bag, and the hot needle mechanism is used to heat the hot connection position of the vest bag, and at the same time, the cutting and heat sealing mechanism is controlled to cut and heat seal the connection end of the vest bag;

[0014] Step S3, after the cutting and heat-sealing are completed, the film-patting plate mechanism is controlled to pat the vest bag downward, so that the end of the vest bag that has been cut and heat-sealed is away from the bottom of the cutting and heat-sealing mechanism;

[0015] Step S4, repeating steps S2 and S3 until the stacked vest bags reach a set number, thereby realizing ironing and joining the vest bags together.

[0016] By adopting the technical solution of the present invention, at least the following beneficial effects are achieved:

[0017] 1. A hot needle adjustment mechanism is arranged between the hot needle mechanism and the frame, and the hot needle adjustment mechanism is designed to include a movable support plate connected to the hot needle mechanism, an adjusting screw rod screwed with the movable support plate along the production direction, a screw rod driving assembly connected with the adjusting screw rod, and a support swing plate, and the movable support plate is connected with the support swing plate through a first linear sliding assembly. In the specific use process, the screw rod driving assembly can be used to drive the adjusting screw rod to drive the movable support plate and the hot needle mechanism to move and adjust along the production direction, so that the production needs of vest bags of various specifications can be well met, the use flexibility is good, and there is no need to purchase multiple sets of production equipment, which can reduce costs.

[0018] 2. By arranging second linear sliding assemblies along the vertical direction at both ends of the film-beating sheet, and connecting the two second linear sliding assemblies with the sheet driving assembly, the sheet driving assembly can be used to drive the second linear sliding assembly to drive the film-beating sheet to reciprocate up and down during operation, thereby well realizing the slapping downward of the cut and heat-sealed end of the vest bag, so that the vest bag leaves the bottom of the cutting and heat-sealing mechanism; at the same time, because the film-beating sheet is relatively thin, and the second linear sliding assemblies are arranged at both ends of the film-beating sheet along the vertical direction, the film-beating sheet occupies very little space between the cutting and heat-sealing mechanism and the ironing needle mechanism, so the distance between the incision and the ironing position of the vest bag can be reliably reduced from 80 mm to 50 mm, thereby greatly improving the use capacity of the vest bag and meeting the production needs of vest bags with a width of less than 300 mm.

[0019] 3. By arranging a first air blowing pipe with a first air blowing hole at the bottom of the film-beating sheet and arranging a second air blowing pipe with a second air blowing hole on the cutting and heat-sealing mechanism, during specific operation, on the one hand, the first air blowing hole of the first air blowing pipe can be used to blow down one end of the cut and heat-sealed vest bag; on the other hand, the second air blowing hole of the second air blowing pipe can be used to blow air forward to form an air flow layer to prevent the bag head of the next vest bag from falling down when conveying the next vest bag, and also to prevent the vest bag beaten downward from floating upward subsequently.

[0020] 4. The first drive assembly, the second drive assembly and the third drive assembly are designed to adopt the same linkage drive structure, so that in the specific implementation, only one second drive motor is needed to link the cutting and hot knife assembly, the pressure plate and the first eccentric wheel to work, which not only helps to reduce the overall cost and make the overall structure more compact and beautiful, but also can ensure the synchronization of the cutting and hot knife assembly, the pressure plate and the first eccentric wheel.

In a specific implementation of the present invention, the first linear sliding assembly 53 includes a first linear guide rail 531 and a first guide block 532, the first linear guide rail 531 is fixed on the support swing plate 51, the first guide block 532 is fixed on the movable support plate 52, the first guide block 532 is slidably assembled and connected to the first linear guide rail 531, and each first linear guide rail 531 is equipped with at least two first guide blocks 532.

[0049] The present invention sets a needle ironing adjustment mechanism 5 between the needle ironing mechanism 3 and the frame 1, and designs the needle ironing adjustment mechanism 5 to include a movable support plate 52 connected to the needle ironing mechanism 3, an adjusting screw rod 54 screwed to the movable support plate 52 along the production direction, a screw rod driving assembly 55 connected to the adjusting screw rod 54, and a support swing plate 51, and the movable support plate 52 is slidably assembled and connected to the support swing plate 51 through a first linear sliding assembly 53, so that in the specific use process, the screw rod driving assembly 55 can be used to drive the adjusting screw rod 54 to drive the movable support plate 52 and the needle ironing mechanism 3 to move and adjust along the production direction, thereby being able to well meet the production needs of vest bags of various specifications, having good flexibility in use, and without the need to purchase multiple sets of production equipment, thereby reducing costs.

[0050] In some embodiments of the present invention, please refer to Figure 4 and Figure 5 As shown, the film-beating plate mechanism 4 includes a film-beating sheet 41, a second linear sliding component 42 and a sheet driving component 43. The film-beating sheet 41 is extended in a direction perpendicular to the production direction, so that the film-beating sheet 41 can better beat down one end of the cut and heat-sealed vest bag; both ends of the film-beating sheet 42 are provided with the second linear sliding components 42 in the vertical direction, the sheet driving component 43 is connected to the two second linear sliding components 42, and the second linear sliding components 42 are driven by the sheet driving component 43 to drive the film-beating sheet 41 to reciprocate up and down, so that the film-beating sheet 41 can continuously beat down one end of the cut and heat-sealed vest bag during the up and down reciprocating movement.

[0051] The present invention arranges second linear sliding components 42 along the vertical direction at both ends of the film-beating sheet 41, and connects the two second linear sliding components 42 with the sheet driving component 43, so that during operation, the sheet driving component 43 can be used to drive the second linear sliding components 42 to drive the film-beating sheet 41 to reciprocate up and down, thereby well achieving the effect of slapping the cut and heat-sealed end of the vest bag downward, so that the vest bag leaves the bottom of the cutting and heat-sealing mechanism 2; at the same time, because the film-beating sheet 41 is relatively thin, and the second linear sliding components 42 are arranged at both ends of the film-beating sheet 41 along the vertical direction, the film-beating sheet 41 occupies very little space between the cutting and heat-sealing mechanism 2 and the ironing needle mechanism 3, so the distance between the incision of the vest bag and the ironing position can be reliably reduced from 80 mm to 50 mm, thereby well improving the use capacity of the vest bag, and meeting the production needs of vest bags with a width of less than 300 mm.

[0052] As a specific embodiment of the present invention, the sheet driving assembly 43 includes a first driving motor 431, a first pulley 432, a first synchronous belt 433, a first connecting shaft 434, a driving disk 435, a first connecting rod 436, a swing arm 437, a first transmission shaft 438 and a second connecting rod 439; the first connecting shaft 434 and the first transmission shaft 438 are both rotatably arranged on the frame 1;

[0053] The first pulley 432 is provided at one end of the first connecting shaft 434 and the output end of the first driving motor 431, the first synchronous belt 433 is sleeved on the two first pulleys 432, the other end of the first connecting shaft 434 is fixedly connected to the middle of the driving disk 435, so that the first connecting shaft 434 can drive the driving disk 435 to rotate; one end of the first connecting rod 436 is eccentrically connected to the driving disk 435, the other end of the first connecting rod 436 is connected to the lower end of the swing arm 437, the upper end of the swing arm 437 is fixedly connected to one end of the first transmission shaft 438; the first transmission shaft 438 is fixedly provided with a connecting arm 4381 at a position corresponding to each second linear sliding assembly 42, the upper end of the second connecting rod 439 is connected to the connecting arm 4381, and the lower end of the second connecting rod 439 is connected to the second linear sliding assembly 42. As a preferred embodiment of the present invention, the first driving motor 431 adopts a servo motor to achieve more accurate control of the movement of the entire film-beating plate mechanism 4.

[0054] When the thin plate driving assembly 43 of the present invention is working, the power output by the first driving motor 431 drives the first synchronous belt 433 to transmit, and the first synchronous belt 433 will drive the first connecting shaft 434 and the driving disk 435 to rotate together during the transmission process; because the first connecting rod 436 is eccentrically connected to the driving disk 435, the driving disk 435 will drive the swing arm 437 to swing back and forth through the first connecting rod 436 during the rotation process; during the reciprocating swing of the swing arm 437, it will drive the second linear sliding assembly 42 to reciprocate up and down through the first transmission shaft 438, the connecting arm 4381 and the second connecting rod 439, and then drive the film-beating thin plate 41 to reciprocate up and down, so that the film-beating thin plate 41 can continuously beat down the cut and heat-sealed vest bags.

[0055] In some embodiments of the present invention, in order to achieve tension adjustment of the first synchronous belt 433, the vest bag production device 100 further includes a synchronous belt tensioning mechanism 6;

[0056] The synchronous belt tensioning mechanism 6 includes a second connecting shaft 61, a top wheel 62 and an adjustment frame 63; the top wheel 62 is rotatably connected to one end of the second connecting shaft 61, the top wheel 62 is abutted on the first synchronous belt 433, and the other end of the second connecting shaft 61 is connected to the adjustment frame 63; the adjustment frame 63 is provided with a long strip adjustment hole 631 along the vertical direction, and the adjustment frame 63 is locked on the frame 1 through the long strip adjustment hole 631, and the adjustment frame 63 can be specifically locked on the frame 1 by bolts. When the tension of the first synchronous belt 433 needs to be adjusted during use, it is only necessary to loosen the adjustment frame 63, and adjust the adjustment frame 63 up and down using the long strip adjustment hole 631, and after adjustment, it is only necessary to lock the adjustment frame 63 on the frame 1 again.

[0057] In some embodiments of the present invention, the second linear sliding assembly 42 includes a second linear guide rail 421 and a second guide block 422, the second linear guide rail 421 is arranged along the vertical direction, and the second linear guide rail 421 is slidably assembled and connected to the second guide block 422, and each second linear guide rail 421 can be equipped with a plurality of second guide blocks 422, the two ends of the film-beating plate 41 are connected to the upper part of the second linear guide rail 421, the thin plate driving assembly 43 is connected to the lower part of the second linear guide rail 421, and the second guide block 422 is fixed on the frame 1.

[0058] In some embodiments of the present invention, the film-beating plate mechanism 4 also includes a first air blowing pipe 44 and a second air blowing pipe 45; the first air blowing pipe 44 is arranged at the bottom of the film-beating sheet 41, and a plurality of first air blowing holes 441 are opened at the bottom of the first air blowing pipe 44; the second air blowing pipe 45 is arranged on the cutting and heat sealing mechanism 2, and the second air blowing pipe 45 is opened on the side facing the film-beating sheet 41.

[0059] The present invention provides a first blowing pipe 44 with a first blowing hole 441 at the bottom of the film-beating sheet 41 and a second blowing pipe 45 with a second blowing hole 451 on the cutting and heat-sealing mechanism 2, so that during specific operation, on the one hand, the first blowing hole 441 of the first blowing pipe 44 can be used to blow down one end of the cut and heat-sealed vest bag; on the other hand, the second blowing hole 451 of the second blowing pipe 45 can be used to blow forward to form an air flow layer to prevent the bag head from falling down when the next vest bag is transported, and also to prevent the vest bag that is beaten down from floating upwards later. Of course, during the specific implementation of the present invention, whether the first blowing pipe 44 and the second blowing pipe 45 are blown can be controlled according to actual needs.

[0060] In some embodiments of the present invention, please refer to Figure 6 and Figure 7As shown, the hot needle adjustment mechanism 5 also includes a swing plate drive cylinder 56, a first eccentric wheel 57, a second transmission shaft 58 and a first drive assembly; the second transmission shaft 58 is rotatably arranged on the frame 1, and a first eccentric wheel 57 is provided on the second transmission shaft 58 at a position corresponding to each adjusting screw rod 54, and one end of the adjusting screw rod 54 away from the screw rod drive assembly 55 abuts against the surface of the first eccentric wheel 57; one end of the swing plate drive cylinder 56 is connected to the frame 1, and the other end of the swing plate drive cylinder 56 is connected to the lower end of the support swing plate 51, and the support swing plate 51 is swingably mounted on the frame 1; the first drive assembly is transmission-connected to the second transmission shaft 58 to drive the second transmission shaft 58 to rotate through the first drive assembly.

[0061] Because the vest bag production device 100 of the present invention is used for actual production, in order to make the stacked vest bags slightly staggered, the hot needle mechanism 3 needs to reciprocate slightly during operation, and the specific movement distance is 1-2mm. To this end, the present invention adopts the method of swingably mounting the support swing plate 51 on the frame 1, and connecting the lower end of the support swing plate 51 to the swing plate driving cylinder 56, and the free end of the adjusting screw rod 54 is pressed against the first eccentric wheel 57, and the first eccentric wheel 57 is connected to the first driving assembly through the second transmission shaft 58, so that when the first driving assembly drives the second transmission shaft 58 to drive the first eccentric wheel 57 to rotate, the support swing plate 51 can slightly reciprocate under the joint action of the first eccentric wheel 57, the adjusting screw rod 54 and the swing plate driving cylinder 56.

[0062] From the above, it can be seen that by adopting the structural design of the hot needle adjustment mechanism 5 of the present invention, not only can the position of the hot needle mechanism 3 be quickly adjusted by using the adjusting screw rod 54 without disassembling the equipment, thereby adapting to the production needs of vest bags of various specifications; at the same time, the adjusting screw rod 54 can also maintain abutment with the surface of the first eccentric wheel 57, so that the support swing plate 51 can slightly reciprocate and swing under the joint action of the first eccentric wheel 57, the adjusting screw rod 54 and the swing plate driving cylinder 56, thereby driving the hot needle mechanism 3 to perform slight reciprocating movements.

[0063] In some embodiments of the present invention, the screw drive assembly 55 includes a screw support seat 551, a third transmission shaft 552, a first bevel gear 553, a second bevel gear 554, a position indicator 555 and a tightening bolt 556;

[0064] The screw support seat 551 is connected to the upper part of the support swing plate 51, and the third transmission shaft 552 is rotatably arranged on the screw support seat 551; both ends of the third transmission shaft 552 are provided with first bevel gears 553, and one end of each of the adjusting screws 54 is provided with a second bevel gear 554, and each of the first bevel gears 553 is meshed with a second bevel gear 554, and the adjusting screw 54 is driven to rotate by rotating the third transmission shaft 552;

[0065] The position indicator 555 is disposed on the screw support seat 551 , and the third transmission shaft 552 passes through the position indicator 555 ; the tightening bolt 556 is threadedly connected to the screw support seat 551 , and the third transmission shaft 552 is tightened by the tightening bolt 556 .

[0066] When the screw drive assembly 55 of the present invention is working, the third transmission shaft 552 can be manually rotated. When the third transmission shaft 552 is rotated, the adjusting screw 54 can be driven to rotate through the meshing action of the first bevel gear 553 and the second bevel gear 554. Since the movable support plate 52 is threadedly connected to the adjusting screw 54, and the adjusting screw 54 itself can only rotate but cannot move, the movable support plate 52 can be driven to move under the action of the adjusting screw 54; and since one end of the two adjusting screws 54 are transmission-connected to the end of the third transmission shaft 552 through the first bevel gear 553 and the second bevel gear 554, the two movable support plates 4 can be reliably driven to move synchronously when the third transmission shaft 552 is rotated. At the same time, because the third transmission shaft 552 passes through the position indicator 555, when the third transmission shaft 552 rotates one circle, the scale of the position indicator 555 increases or decreases by 1mm, so that the user can intuitively know the distance A between the incision of the vest bag and the ironing position during the adjustment process, which can bring convenience to the actual adjustment. In addition, during the specific use of the present invention, when it is necessary to adjust the position of the ironing needle mechanism 3, it is only necessary to loosen the tightening bolt 556 outward so that the third transmission shaft 552 can rotate; and after adjusting the position of the ironing needle mechanism 3, it is only necessary to tighten the tightening bolt 556 inward so that the tightening bolt 556 can fix the third transmission shaft 552, thereby ensuring that the third transmission shaft 552 cannot continue to rotate.

[0067] In some embodiments of the present invention, please refer to Fig.10As shown, the hot needle mechanism 3 includes a support beam 31, a hot needle assembly 32, a pressing plate 33 and a second driving assembly; the support beam 31 is connected between two movable support plates 52, the hot needle assembly 32 is arranged on the support beam 31, and the pressing plate 33 is arranged above the support beam 31; the second driving assembly is connected to the pressing plate 33, and the pressing plate 33 is driven by the second driving assembly to move up and down. In a specific implementation of the present invention, the hot pin assembly 32 includes a hot pin 321, a first heating block 322, a hot pin bracket 323, a lifting drive cylinder 324 and a connecting frame 325; the hot pin 321 is located below the support beam 31, and the support beam 31 and the pressure plate 33 are both provided with hot pin holes 34 at the positions corresponding to the hot pin 321; the hot pin 321 is installed on the first heating block 322, and the first heating block 322 is arranged on the hot pin bracket 323, the connecting frame 325 is connected to the support beam 31, the lifting drive cylinder 324 is fixed on the connecting frame 325, and the movable end of the lifting drive cylinder 324 is connected to the hot pin bracket 323. When the ironing needle mechanism 3 is working, after the vest bag is transported forward to the right position, the lifting drive cylinder 324 is controlled to drive the ironing needle 321 to rise, and the second drive component is controlled to drive the pressing plate 33 to descend. Because the vest bag is located between the supporting beam 31 and the pressing plate 33, the pressing plate 33 will press the vest bag tightly against the supporting beam 31, and the ironing needle 321 will pass through the ironing position of the vest bag when passing through the ironing needle hole 34.

[0079] Step S1, determining the distance between the incision and the hot-joining position of the vest bag according to the specifications of the vest bag to be produced, and using the hot-joining adjustment mechanism 5 to drive the hot-joining mechanism 3 to adjust the position according to the distance between the incision and the hot-joining position; because in the actual production process, the distance requirements between the incision and the hot-joining position are different for vest bags of different specifications, it is necessary to first determine the distance according to the specifications of the vest bag, and then use the hot-joining adjustment mechanism 5 to adjust the position of the hot-joining mechanism 3 so that the distance between the incision and the hot-joining position can be adapted to the vest bag of corresponding specifications;

[0080] Step S2, during the production process, the hot needle 321 of the hot needle mechanism 3 is controlled to extend upward. When the vest bag is delivered to the right place, the pressing plate 33 of the hot needle mechanism 3 is controlled to descend and press the vest bag tightly so that the hot needle 321 passes through the hot-joining position of the vest bag, so as to realize positioning of the vest bag, so that the vest bag will not deviate during the cutting process, and the hot needle mechanism 3 is used to heat the hot-joining position of the vest bag, and at the same time, the cutting and heat-sealing mechanism 2 is controlled to cut and heat-seal the connecting end of the vest bag; in the actual production process of the present invention, it is necessary to first control the lifting drive cylinder 324 to drive the hot needle 321 to rise to the top of the supporting beam 31, and keep the hot needle 321 motionless, and then when the vest bag is delivered to the right place, the second driving component is used to drive the pressing plate 33 to press the vest bag down and string it onto the hot needle 321; at the same time, the hot needle 321 of the hot needle mechanism 3 will keep heating the hot-joining position of the vest bag, so that each vest bag on the string can be reliably hot-joined together;

[0081] Step S3, after the cutting and heat-sealing are completed, the film-slapping plate mechanism 4 is controlled to slap the vest bag downward, so that the end of the vest bag that has been cut and heat-sealed is away from the bottom of the cutting and heat-sealing mechanism 2, so as to prevent the vest bag that has been cut and heat-sealed from being cut by the cutting and heat-sealing mechanism 2;

[0082] Step S4, repeat step S2 and step S3 until the stacked vest bags reach the set number, so as to realize the ironing of the vest bags together; at the same time, when it is necessary to take out the stacked vest bags, control the lifting drive cylinder 324 to drive the ironing needle 321 to descend and return to its position.
