[0043] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0044] The core of the present utility model is to provide a packaging bag manufacturing device capable of punching out a heart - shaped pattern, which can cut out a beautiful heart - shaped pattern and is convenient for subsequent manual tearing of the packaging bag.

[0045] It should be noted that in this embodiment, the orientation or positional relationship indicated by "upper", "lower", "front", "rear", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present application.

[0046] Please refer to Figures 3 to 5 , the present application provides a packaging bag manufacturing device capable of punching out a heart - shaped pattern, including a frame 1. A heart - shaped cutting device 10 is provided on the frame 1. The heart - shaped cutting device 10 includes a driver 112, a male die and a female die which are opposite and spaced apart. A plurality of cutting blocks 108 arranged at equal intervals in a heart - shaped pattern are provided at the end of the female die facing the male die. An elastic pad 111 which is in extrusion fit with the cutting blocks 108 is provided at the end of the male die facing the female die. The driver 112 is connected to the male die and is used to drive the male die to move towards the female die.

[0047] It should be noted that, please refer to Figure 1 and Figure 2 , the packaging bag manufacturing device usually consists of a film feeding device 2, a film damping device 3, a rotary cutting knife device 5, a waste edge winding device 6, a filling device, a sealing device and a round - corner cutting knife device 11 to successively perform operations such as feeding, cutting, forming, filling, sealing and cutting on the film to form the output packaging bag. And the packaging bag manufacturing device capable of punching out a heart - shaped pattern in the present application has a heart - shaped cutting device 10. The heart - shaped cutting device 10 is installed below the sealing device to cut a heart - shaped pattern on the packaging bag that has been sealed with filler. Therefore, the packaging bag manufacturing device capable of punching out a heart - shaped pattern in the present application integrates operations such as feeding, cutting, forming, filling, sealing, making a heart - shaped pattern and cutting. There is no need to additionally install a pattern processing device on the production line, saving floor space and production costs.

[0048] In addition, the heart-shaped cutter device 10 includes a male mold, a female mold, and a driver 112. A heart-shaped cutter is provided at the end of the female mold facing the male mold. The heart-shaped cutter is composed of a plurality of cutter blocks 108 arranged at equal intervals in a heart shape. An elastic pad 111 is provided at the end of the male mold facing the female mold, and the male mold is connected to the driver 112. In this way, after the rolled film sequentially completes processes such as feeding, cutting, forming, filling, and sealing through the device, a packaged bag with sealed filler is formed. The end of the packaged bag falls between the female mold and the male mold. Then, the driver 112 is controlled to drive the male mold to move towards the female mold, so that the elastic pad 111 of the male mold pushes the packaged bag towards the heart-shaped cutter for stamping. The plurality of cutter blocks 108 penetrate the packaged bag, and a heart-shaped pattern is cut out on the packaged bag. It should be noted that since the heart-shaped cutter is a discontinuous design, the edge of the heart-shaped pattern is composed of alternating connecting segments and vacant segments. During the punching process, the cut-off part of the vacant segment is still connected to the heart-shaped pattern. When the heart-shaped cutter continues to squeeze the elastic pad 111, it can stretch the heart-shaped pattern, making the heart-shaped pattern have a concave-convex three-dimensional aesthetic compared to the packaged bag, so as to cut out a beautiful heart-shaped pattern, and the edge of the heart-shaped pattern has vacant segments, which is convenient for manually tearing the packaged bag later.

[0049] To enhance the three-dimensional sense of the heart-shaped pattern and improve the service life of the female mold at the same time, on the basis of the above embodiment, please refer to Figure 4 and Figure 5 , the female mold includes a female mold body 101, a pressing plate 102, and an elastic buffer member provided therebetween. A heart-shaped through hole 107 for arranging a plurality of cutter blocks 108 is provided on the pressing plate 102, and the heart-shaped through hole 107 is adapted to the shape of the heart-shaped elastic pad 111 and is arranged opposite to it.

[0050] Specifically, a heart-shaped through hole 107 is provided on the pressing plate 102, and a plurality of cutter blocks 108 are arranged at equal intervals in the heart-shaped through hole 107. At this time, the elastic pad 111 facing the heart-shaped through hole 107 needs to be set in a heart shape, and the shape of the heart-shaped elastic pad 111 is adapted to the shape of the heart-shaped through hole 107, so that the heart-shaped elastic pad 111 can press the packaging bag into the heart-shaped through hole 107 for cutting. In addition, the female die body 101 is a fixed component, and an elastic buffer member is arranged between the female die body 101 and the pressing plate 102. The elastic buffer member has the characteristics of buffering and shock absorption, as well as storing and releasing energy through elastic deformation. In this way, when the male die presses towards the female die, the pressing plate 102 squeezes the elastic buffer member backward, and the elastic buffer member is compressed to absorb and store a certain amount of impact energy, that is, it plays a role of buffering and shock absorption for the pressing plate 102 and the female die body 101, which is beneficial to improving the service life of the female die. After the punching and cutting are completed, when the male die initially moves away from the female die, that is, after the punching force of the pressing plate 102 initially disappears, the elastic buffer member releases the stored impact energy, that is, it provides a rebounding force to the pressing plate 102, and the heart-shaped cutter can continue to squeeze the elastic pad 111 forward, and at the same time drive the heart-shaped pattern to continue to stretch forward, so as to further enhance the three-dimensional sense of the heart-shaped pattern.

[0051] To achieve precise control of the punching and cutting stroke of the male die, on the basis of the above-mentioned embodiment, first position sensors and second position sensors that are both signal-connected to the control device are respectively provided on the opposite end faces of the pressing plate 102 and the male die.

[0052] It can be understood that the maximum distance that the driver 112 drives the male die to move towards the female die is the punching and cutting stroke of the male die. The size of the punching and cutting stroke determines the punching force of the male die on the pressing plate 102, and the punching force also determines the three-dimensional degree of the heart-shaped pattern. Therefore, the present application further includes a control device. The first position sensor is arranged on the end face of the pressing plate 102 facing the male die, and is used to collect the position information of the pressing plate 102 in real time and transmit it to the control device. The second position sensor is arranged on the end face of the male die facing the pressing plate 102, and is used to collect the position information of the male die in real time and transmit it to the control device. The control device can calculate the real-time distance value between the male die and the pressing plate 102, and compare it with the preset distance value. When the real-time distance value reaches the preset distance value, the control device transmits a return signal to the driver 112, so that the driver 112 drives the male die to reset. Therefore, by adopting the above method, the punching and cutting stroke of the male die can be precisely controlled, not only can the punching force of the male die on the pressing plate 102 be precisely controlled to ensure that the pressing plate 102 is not damaged, but also the mutual extrusion depth between the heart-shaped elastic pad 111 and the heart-shaped cutter can be controlled to ensure that the heart-shaped pattern has a beautiful three-dimensional sense, and at the same time ensure that the elastic pad 111 is not damaged.

[0053] Considering the fixing method between the pressing plate 102 and the female die body 101, on the basis of the above-mentioned embodiment, please refer to Figure 4 and Figure 5, a clamping groove 105 is provided on the side wall of the female mold body 101, and a clamping block 106 is provided on the side wall of the pressing plate 102 corresponding to the position of the clamping groove 105. The clamping block 106 is slidably clamped in the clamping groove 105.

[0054] Specifically, the clamping groove 105 is provided in the middle of the upper side wall of the female mold body 101. The clamping groove 105 extends a certain length along the moving direction of the pressing plate 102. The clamping block 106 is provided in the middle of the upper side wall of the pressing plate 102. The clamping block 106 is adapted to the shape of the clamping groove 105 and the two are movably clamped, so as to realize that the pressing plate 102 is movably installed on the female mold body 101 relative to the female mold body 101, and the pressing plate 102 and the female mold body 101 are connected by a clamping method, which is convenient for installation and disassembly.

[0055] Considering the specific structure of the elastic buffer member, on the basis of the above embodiments, please refer to Figure 4 and Figure 5 , the elastic buffer member includes four guide shafts 103 and four compression springs 104 corresponding to them one by one. The four guide shafts 103 are arranged symmetrically in pairs, and one end of the guide shaft 103 is fixed on the end face of the pressing plate 102 facing the female mold body 101, and the other end is movably penetrated through the female mold body 101. The compression spring 104 is sleeved on the corresponding guide shaft 103 and is located between the female mold body 101 and the pressing plate 102.

[0056] Specifically, four perforations are arranged symmetrically in pairs on the mold body, that is, the four perforations are arranged in a rectangle. Four mounting holes corresponding to the four perforations are arranged on the pressing plate 102. The front end of the guide shaft 103 is fixed in the mounting hole, and the rear end is movably penetrated through the perforation corresponding to the mounting hole, and the compression spring 104 is sleeved on the guide shaft 103 and is located between the female mold body 101 and the pressing plate 102. It can be seen that during the forward and backward movement of the pressing plate 102, the spring plays a role in buffering and damping and providing a rebounding force. The four guide shafts 103 all play a role in supporting and guiding to prevent the pressing plate 102 from shifting and affecting the quality of the heart-shaped pattern cut out, that is, to ensure the correct movement track of the pressing plate 102. Therefore, the elastic buffer member arranged with the above structure not only has the functions of buffering and damping and providing a rebounding force, and this function realizes enhancing the three-dimensional sense of the heart-shaped pattern and improving the service life of the female mold at the same time; the elastic buffer member also has the function of ensuring the correct movement track of the pressing plate 102, and this function is beneficial to improving the quality of the heart-shaped pattern.

[0057] To ensure the correct movement track of the male mold, on the basis of the above embodiments, please refer to Figure 4 and Figure 5, the male mold includes a male mold body 109 and two guide plates 110. An elastic pad 111 is provided on the end face of the male mold body 109 facing the heart-shaped through hole 107. The two guide plates 110 are symmetrically arranged on both side walls of the male mold body 109 and both extend through the pressing plate 102 and the female mold body 101 in sequence.

[0058] Specifically, two guide plates 110 are symmetrically provided on both sides of the male mold body 109. First long holes are symmetrically penetrated through both sides of the pressing plate 102, and second long holes are symmetrically penetrated through both sides of the female mold body 101. The guide plates 110 pass through the first long holes and the second long holes in sequence. The end face of the male mold body 109 facing away from the pressing plate 102 is connected to the output shaft of the driver 112. During the forward and backward movement of the male mold body 109, the two guide plates 110 play a guiding role to ensure the correct movement trajectory of the male mold body 109, so as to ensure that the elastic pad 111 and the heart-shaped through hole 107 maintain an accurate relative position, which is beneficial to improving the quality of the heart-shaped pattern.

[0059] Furthermore, four guide shafts 103 are respectively arranged between the four corners of the female mold body 101 and the pressing plate 102, and the guide plates 110 are placed between the two guide shafts 103 on the same side as them to avoid position interference between the guide plates 110 and the guide shafts 103, thereby ensuring the safe and stable operation of the punching operation.

[0060] To improve the firmness of the heart-shaped cutter device 10 and save installation space, on the basis of the above embodiments, please refer to Figure 3 , the heart-shaped cutter device 10 further includes a box-shaped bracket 113. The female mold, the male mold and the driver 112 are coaxially arranged along the length direction of the box-shaped bracket 113 inside the box-shaped bracket 113.

[0061] Specifically, due to the strong structural stability of the box-shaped bracket 113 and the installation space inside it, the box-shaped bracket 113 is installed on the equipment frame 1, and the female mold, the male mold and the driver 112 are all installed inside the box-shaped bracket 113, thereby improving the firmness of the heart-shaped cutter device 10. In addition, the female mold body 101 in the female mold is fixed at the rear end of the box-shaped bracket 113, the driver 112 is fixed at the front end of the box-shaped bracket 113, the male mold body 109 is movably located between the pressing plate 102 and the driver 112 in the female mold, and the output shafts of the female mold, the male mold and the driver 112 are coaxially arranged, so that the female mold, the male mold and the driver 112 are compactly arranged inside the box-shaped bracket 113, thus saving installation space.

[0062] It should be noted that two sockets 114 for the packaging bag to pass through are symmetrically provided on the upper side wall and the lower side wall of the box-shaped bracket 113. The sockets 114 are located on the side of the female mold facing the male mold to realize the feeding and discharging of the packaging bag.
