Description

Technical Field

[0001] This invention relates to the field of bag making technology, specifically a bag making hot stamping device that controls the feed through mechanical cooperation. Background Technology

[0002] A bag-making machine is a machine that produces various plastic or other material packaging bags. Its processing range includes packaging bags of various sizes, thicknesses, and specifications made of plastic or other materials. Generally speaking, packaging bags are the main product.

[0003] Currently, packaging bags are used in various fields, especially in food and pharmaceutical packaging. As people's living standards improve, their demand for aesthetics also increases, leading to higher requirements for the style and appearance of packaging bags. To meet market demands and ensure packaging bags are exquisite and highly recognizable, hot stamping is commonly used to imprint patterns on the surface of the bags. Most hot stamping machines on the market currently use conveyor belts or rewind rollers to feed the bags to the hot stamping machine. Once the packaging bag is below the machine, a cylinder drives the machine to move up and down to complete the hot stamping operation. Therefore, to ensure the quality of the hot stamping process... For the hot stamping machine to achieve the same stamping position on the packaging bags, a connection needs to be established between the feeding structure and the cylinder. In existing hot stamping devices, after the packaging bags are transported to the designated position, electronic devices such as sensors are used to detect the transport position of the packaging bags. After the sensing device receives the signal, it sends a command to the cylinder, thereby driving the cylinder to move the hot stamping machine. During this process, the sensing device is easily affected by external environmental factors such as temperature, network load, humidity, and electromagnetic interference, which may cause the packaging bags to fail to move to the designated position. In this case, after the hot stamping machine performs the hot stamping operation, it will result in different stamping positions or depths between the packaging bags, ultimately affecting the product quality of the packaging bags. Summary of the Invention

[0004] The purpose of this invention is to provide a bag-making hot stamping device that controls the feeding through mechanical means, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A bag-making hot stamping device with feed controlled by mechanical cooperation includes: a support frame, on which a feeding component and a hot stamping component are provided. The feeding component includes a reciprocating component slidably disposed on the support frame. When the feeding component is activated, it can drive the reciprocating component to reciprocate along the length direction of the support frame.

[0007] The reciprocating component is provided with a pressing component, which is connected to the reciprocating component through an elastic locking component. When the reciprocating component moves to the end of its stroke, the elastic locking component cooperates with a trigger component provided on the support frame to change the contact state between the pressing component and the placement platform on the support frame, thereby enabling the packaging bag placed on the placement platform to be transported to the area below the hot stamping component.

[0008] The hot stamping component is connected to the feeding component via a linkage component. During the process of the pressing part transporting the packaging bag and resetting, the linkage component can drive the hot stamping component to move, thereby hot stamping the packaging bag.

[0009] As described above, the bag making hot stamping device with feed controlled by mechanical cooperation includes a hot stamping component and a drive structure. The lifting component includes a lifting plate, and two sets of lifting plates are provided. The two sets of lifting plates are slidably disposed on the left and right side walls of the support frame. A hot stamping machine is fixedly disposed between the two sets of lifting plates, and a moving groove is provided on the side of each set of lifting plates away from the hot stamping machine.

[0010] As described above, the bag making hot stamping device with feed controlled by mechanical cooperation has two sets of drive structures. Each set of drive structures includes a turntable rotatably mounted on the support frame. A protruding post is fixedly provided on the side of the turntable facing the lifting plate, and the protruding post is slidably disposed in the moving groove.

[0011] As described above, the bag making hot stamping device with feed controlled by mechanical cooperation: the reciprocating component includes a reciprocating plate, and two sets of the reciprocating plates are provided. The two sets of reciprocating plates are slidably arranged on the left and right sides of the support frame, and each set of the reciprocating plates is provided with a sliding groove.

[0012] As described above, the bag making and hot stamping device with feeding controlled by mechanical cooperation includes two sets of driving components disposed on the left and right side walls of the support frame. Each set of driving components includes pulleys rotatably mounted on the support frame. Two sets of pulleys are disposed along the length of the support frame. A belt is disposed between the two sets of pulleys. A protruding post is fixedly disposed on the belt. The protruding post is slidably disposed in the groove.

[0013] As described above, the bag making and hot stamping device with feed controlled by mechanical cooperation includes a pressing component comprising lifting rods slidably disposed on two sets of reciprocating plates, the two sets of lifting rods being fixedly connected by a connecting plate, and a pressing plate being fixedly disposed at one end of the two sets of lifting rods facing the placement platform.

[0014] As described above, the bag making hot stamping device with feed controlled by mechanical cooperation: the elastic locking assembly includes an elastic structure and a locking element. The elastic structure includes a fixed sleeve disposed on the lifting rod. A spring is slidably disposed inside the fixed sleeve. One end of the spring abuts against the lifting rod, and the other end abuts against a telescopic rod slidably disposed inside the fixed sleeve. A pulley is rotatably mounted on the end of the telescopic rod away from the spring.

[0015] As described above, the bag making and hot stamping device with feed controlled by mechanical cooperation includes a locking block fixedly mounted on the reciprocating plate, and the locking block is provided with a first locking groove, a second locking groove, a first inclined surface, and a second inclined surface.

[0016] The bag-making hot stamping device described above, which controls the feed through mechanical cooperation, includes a first wedge block and a second wedge block fixedly mounted on the support frame.

[0017] As described above, the bag-making hot stamping device with feed controlled by mechanical cooperation includes a second linkage wheel and a transmission wheel rotatably mounted on the support frame. The transmission wheel is connected to a rotating rod coaxially fixed on one of the pulleys via a transmission belt. The second linkage wheel is connected to a first linkage wheel rotatably mounted on the support frame via a linkage belt. A driving wheel is coaxially fixed on the transmission wheel. The driving wheel cooperates with a driven wheel coaxially fixed on the second linkage wheel, which can drive the second linkage wheel to rotate.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] In this invention, by setting up a feeding component, a hot stamping component, and a linkage component, the transportation of the packaging bag and the hot stamping operation of the hot stamping machine can be driven to proceed sequentially by mechanical cooperation. When the feeding component is in operation, due to the cooperation of the elastic locking component, the pressing plate can only drive the packaging bag laid on the placement platform to move towards the hot stamping device. Moreover, the travel distance of each transport is the same, which can ensure that the position of the hot stamping component on the packaging bag is the same.

[0020] Furthermore, with the cooperation of the linkage components, the feeding component can drive the hot stamping component to move during the reset process, thereby driving the hot stamping machine to complete the hot stamping operation of the packaging bag.

[0021] Compared to traditional methods, using mechanical transmission ensures that the lifting height of the hot stamping machine and the transport distance of the packaging bag remain consistent, resulting in consistent hot stamping depth and position on the final packaging bag, thereby improving the product quality of the packaging bag.

[0033] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0034] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0035] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0036] Please see Figures 1-10 In this embodiment of the invention, a bag-making hot stamping device with feed controlled by mechanical means includes:

[0037] A support frame 1 is provided with a feeding assembly and a hot stamping assembly. The feeding assembly includes a reciprocating component that is slidably disposed on the support frame 1. When the feeding assembly is activated, it can drive the reciprocating component to reciprocate along the length direction of the support frame 1.

[0038] For preferred options, please refer to [link / reference]. Figure 1 The aforementioned support frame 1 is configured in a box-shaped structure, with its front end (left side) connected to the bag-making device and its rear end (right side) connected to the bag-cutting device (not shown in the figure). The packaging bags produced by the front-end bag-making device are continuously collected at the front end of the support frame 1. Initially, the rolled packaging bags are placed on the placement platform 2. After being transported by the feeding component, the packaging bags placed on the placement platform 2 can move forward a distance to the hot stamping position below the hot stamping component. After the hot stamping component completes the hot stamping operation, the feeding component can transport the packaging bags that have not been hot stamped to the hot stamping position again, and at the same time move the hot stamped packaging bags to the bag-cutting device so that the subsequent cutting device can divide the continuous packaging bags to obtain complete packaging bags.

[0039] For details, please refer to Figure 1 , Figure 2 , Figure 7 , Figure 8The hot stamping assembly includes a lifting component and a driving structure. The lifting component includes a lifting plate 7. Two sets of lifting plates 7 are provided. The two sets of lifting plates 7 are slidably disposed on the left and right side walls of the support frame 1. A hot stamping machine 8 is fixedly disposed between the two sets of lifting plates 7. Each set of lifting plates 7 has a moving groove 701 on the side away from the hot stamping machine 8.

[0040] Specifically, the aforementioned lifting plate 7 is slidably disposed in the through groove 102 opened on the side wall of the support frame 1. Under the restriction of the through groove 102, the lifting plate 7 can only move up and down in the vertical direction, thereby driving the hot stamping machine 8 to move closer to the placement platform 2 to complete the hot stamping operation on the packaging bag.

[0041] Furthermore, the drive structure is provided in two sets, each set of the drive structure includes a turntable 9 rotatably mounted on the support frame 1, and a protruding post 901 is fixedly provided on the side of the turntable 9 facing the lifting plate 7, and the protruding post 901 is slidably disposed in the moving groove 701.

[0042] In detail, in the initial state, the hot stamping machine 8 is far away from the placement platform 2. When the turntable 9 is driven by an external force to rotate one revolution, the protrusion 901 can slide in the moving groove 701. During the sliding process of the protrusion 901, the contact and pressure generated by the protrusion 901 on the groove wall of the moving groove 701 can force the lifting plate 7 to reciprocate along the through groove 102 once, thereby driving the hot stamping machine 8 to first descend towards the placement platform 2 until the hot stamping machine 8 completes the hot stamping operation on the packaging bag on the placement platform 2, and then rises back to the initial position so that the packaging bag can be transported.

[0043] For further details, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The reciprocating component includes a reciprocating plate 3, and two sets of the reciprocating plates 3 are provided. The two sets of reciprocating plates 3 are slidably disposed on the left and right sides of the support frame 1, and each set of the reciprocating plates 3 is provided with a sliding groove 301.

[0044] For details, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 The aforementioned reciprocating plate 3 is fixedly provided with a snap-fit ​​rod 302. Two sets of snap-fit ​​rods 302 are symmetrically arranged along the length direction of the reciprocating plate 3. The two sets of snap-fit ​​rods 302 are slidably arranged in the snap-fit ​​grooves 101 opened on the side wall of the support frame 1. With the cooperation between the snap-fit ​​rods 302 and the snap-fit ​​grooves 101, the reciprocating plate 3 can only reciprocate along the length direction of the support frame 1, thereby driving the pressing parts set on the reciprocating parts to transport the packaging bags laid on the placement platform 2.

[0045] The feeding assembly also includes two sets of driving components disposed on the left and right side walls of the support frame 1. Each set of driving components includes pulleys 15 rotatably mounted on the support frame 1. Two sets of pulleys 15 are disposed along the length of the support frame 1. A belt 4 is disposed between the two sets of pulleys 15. A protruding post 401 is fixedly disposed on the belt 4. The protruding post 401 is slidably disposed in the groove 301.

[0046] Specifically, one of the two sets of pulleys 15 is coaxially and fixedly connected to the output shaft of the motor 6, which is fixedly mounted on the support frame 1, in combination with... Figure 1 , Figure 2 In the initial state, the reciprocating plate 3 is close to the front end of the support frame 1. When performing the hot stamping operation on the packaging bag, the motor 6 is started first. Then, the output shaft of the motor 6 can drive the pulley 15 to rotate continuously clockwise (refer to...). Figure 2 (Description) At this time, the pulley 15 can drive the belt 4 to rotate continuously clockwise. During this process, the protrusion 401 fixed on the belt 4 can slide in the groove 301. During the movement of the protrusion 401, the contact and compression of the protrusion 401 against the groove wall of the groove 301 can drive the reciprocating plate 3 to reciprocate in the snap-fit ​​groove 101. When the reciprocating plate 3 reciprocates, the cooperation between the elastic locking component and the pressing component enables the pressing component to perform the packaging bag transportation work normally, thereby delivering the packaging bag to the hot stamping component so that the subsequent hot stamping component can perform the hot stamping operation normally.

[0047] For details, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 The pressing component is disposed on the reciprocating component, and the pressing component is connected to the reciprocating component through an elastic locking component. When the reciprocating component moves to the end of its stroke, the elastic locking component cooperates with the trigger component disposed on the support frame 1 to change the contact state between the pressing component and the placement platform 2 on the support frame 1, thereby enabling the packaging bag placed on the placement platform 2 to be transported to the bottom of the hot stamping component.

[0048] The pressing component includes lifting rods 5 slidably disposed on two sets of reciprocating plates 3. The two sets of lifting rods 5 are fixedly connected by a connecting plate 502, and a pressing plate 501 is fixedly disposed on one end of the two sets of lifting rods 5 facing the placement platform 2.

[0049] The elastic locking assembly includes an elastic structure and a locking element. The elastic structure includes a fixed sleeve 17 disposed on the lifting rod 5. A spring 18 is slidably disposed inside the fixed sleeve 17. One end of the spring 18 abuts against the lifting rod 5, and the other end abuts against a telescopic rod 19 slidably disposed inside the fixed sleeve 17. A pulley is rotatably mounted on the end of the telescopic rod 19 away from the spring 18.

[0050] In particular, please see Figure 6 The spring 18 is always in a compressed state. In the compressed state, the spring 18 can push the telescopic rod 19 to tend to move away from the lifting rod 5. At the same time, with the cooperation of the locking member, the height of the lifting rod 5 can be fixed so that the pressing plate 501 can be kept away from or close to the placement platform 2, thereby enabling the pressing plate 501 to complete the directional transportation operation of the packaging bag.

[0051] Specifically, the locking component includes a locking block 16 fixedly mounted on the reciprocating plate 3. The locking block 16 is provided with a first locking groove 1601, a second locking groove 1602, a first inclined surface 1603, and a second inclined surface 1604. The first locking groove 1601 and the first inclined surface 1603 are symmetrical with the second inclined surface 1604 and the second locking groove 1602.

[0052] The triggering element includes a first wedge block 1401 and a second wedge block 1402 fixedly mounted on the support frame 1;

[0053] For preferred options, please refer to [link / reference]. Figure 3 , Figure 4 The first wedge block 1401 and the second wedge block 1402 are configured in a near-right trapezoidal structure. This right trapezoidal structure includes a set of inclined trigger surfaces 1403. Specifically, the first wedge block 1401 and the second wedge block 1402 are respectively disposed at both ends of the latching groove 101, and their positions are as follows: Figure 4 As shown, the height of the first wedge block 1401 is lower than that of the second wedge block 1402;

[0054] In the initial state, please refer to Figure 3The pressing plate 501 is close to the front end of the support frame 1. The pulley on the telescopic rod 19 engages with the second locking groove 1602. At this time, the pressing plate 501 contacts the placement platform 2 and can press the packaging bag onto the placement platform 2. Then, the motor 6 is started. The belt 4, with the cooperation between the protrusion 401 and the reciprocating plate 3, drives the reciprocating plate 3 to move along the snap-fit ​​groove 101 toward the hot stamping machine 8. During this process, due to the pressing of the packaging bag by the pressing plate 501, the reciprocating plate 3 can drive the packaging bag toward the hot stamping machine 8. When the reciprocating plate 3 moves close to the end of the stroke of the snap-fit ​​groove 101, the fixed sleeve 17 can contact the trigger surface 1403 on the first wedge block 1401. With the continued movement of the reciprocating plate 3, the contact compression generated by the trigger surface 1403 on the fixed sleeve 17 can force the fixed sleeve 17 to engage. The cylinder 17 drives the lifting rod 5 and the pressing plate 501 to rise. During this process, the pulley separates from the second locking groove 1602 and then slides along the second inclined surface 1604. When sliding, the compression of the pulley by the second inclined surface 1604 can force the telescopic rod 19 to retract into the fixed sleeve 17, which increases the elastic potential energy of the spring 18. When the reciprocating plate 3 moves to the end of the stroke of the snap-fit ​​groove 101, the pulley crosses the axis of symmetry between the second inclined surface 1604 and the first inclined surface 1603 and contacts the first inclined surface 1603. At this time, the spring 18 releases its elastic potential energy, which can push the telescopic rod 19 to move towards the reciprocating plate 3. At the same time, under the guidance of the first inclined surface 1603, the pulley finally contacts the first locking groove 1601. At this time, the lifting rod 5 and the pressing plate 501 can quickly separate from the packaging bag.

[0055] Next, belt 4 drives reciprocating plate 3 to move in the opposite direction. During this process, since pressing plate 501 is separated from placement platform 2, the position of packaging bag will remain unchanged so that the subsequent hot stamping component can perform hot stamping action. When reciprocating plate 3 moves to a position near the end of the stroke, fixing sleeve 17 contacts the trigger surface 1403 of second wedge block 1402. Subsequently, as reciprocating plate 3 continues to move, second wedge block 1402 can force pulley to separate from first locking groove 1601 and slide along first inclined surface 1603 until pulley contacts second inclined surface 1604. Spring 18 releases elastic potential energy, which can force pulley to quickly contact second locking groove 1602, thereby enabling pressing plate 501 to quickly contact placement platform 2 and return to the state of contacting placement platform 2 and pressing packaging bag, so that when pressing plate 501 moves with reciprocating plate 3, it can transport packaging bag toward hot stamping component again.

[0056] By repeating the above operations, the packaging bag can be continuously transported to the hot stamping assembly so that the hot stamping assembly can perform the hot stamping operation.

[0057] For further details, please refer to [link / reference]. Figure 2 , Figure 7 , Figure 9 , Figure 10 The hot stamping component is connected to the feeding component through a linkage component. During the process of the pressing part carrying the packaging bag and resetting, the linkage component can drive the hot stamping component to move, thereby hot stamping the packaging bag.

[0058] The linkage assembly includes a second linkage wheel 11 rotatably mounted on the support frame 1 and a transmission wheel 21. The transmission wheel 21 is connected to a rotating rod 12 coaxially fixed on one of the pulleys 15 via a transmission belt. The second linkage wheel 11 is connected to a first linkage wheel 10 rotatably mounted on the support frame 1 via a linkage belt. A driving wheel 13 is coaxially fixed on the transmission wheel 21. The driving wheel 13 cooperates with a driven wheel 20 coaxially fixed on the second linkage wheel 11, which can drive the second linkage wheel 11 to rotate.

[0059] It should be further explained that the first linkage wheel 10 is fixed coaxially with the turntable 9, and the radius of the transmission wheel 21 is many times the radius of the rotating rod 12. When the motor 6 drives the pulley 15 to drive the belt 4 to rotate one revolution, the rotating rod 12, which is fixed coaxially with the pulley 15, can only drive the transmission wheel 21 to rotate one revolution. The radius of the second linkage wheel 11 is four times the radius of the first linkage wheel 10. The driving wheel 13 is provided with a fixing rod 1301 and a positioning block 1302. The driven wheel 20 is provided with four sets of grooves 2001 at equal intervals along its circumference.

[0060] In summary, when the motor 6 drives the pulley 15 to work and drives the belt 4 to rotate one revolution, due to the proportional relationship between the rotating rod 12 and the transmission wheel 21, the transmission wheel 21 can only drive the driving wheel 13 to rotate one revolution. During the first three-quarters of the revolutions of the driving wheel 13, the reciprocating plate 3 has completed the transportation process of the packaging bag and returned to the middle of the snap-fit ​​groove 101. During this process, the positioning block 1302 cooperates with the driven wheel 20 to lock the position of the driven wheel 20 so that the positions of the second linkage wheel 11, the first linkage wheel 10 and the turntable 9 remain unchanged, thereby fixing the position of the hot stamping machine 8 away from the placement platform 2.

[0061] When the drive wheel 13 has rotated one-quarter of a turn, the fixed rod 1301 can engage with the groove 2001, thereby driving the driven wheel 20 and the transmission wheel 21 to rotate one-quarter of a turn in opposite directions. During this process, the second linkage wheel 11 can drive the first linkage wheel 10 to rotate one turn, so that the turntable 9 rotates one turn, driving the hot stamping machine 8 to perform one lowering and raising operation, thereby completing the hot stamping of the packaging bag.

[0062] During operation, the aforementioned feeding component drives the hot stamping component to control the hot stamping machine 8 to perform hot stamping on the packaging bag. Compared with traditional bag-making hot stamping devices that use sensors, cylinders, and conveyor belts, in this invention, the feeding component and the hot stamping component are driven and controlled by the same drive source, so that the transportation of the packaging bag and the lifting and lowering of the hot stamping machine 8 can be completed sequentially. In traditional hot stamping devices, the hot stamping machine 8 usually uses a cylinder or electric telescopic drive to complete the lifting and lowering process. Cylinders usually require air source support, which is costly. Furthermore, uneven damage to the inner sealing ring or the presence of obstacles may lead to uneven force, resulting in inconsistent lifting and lowering heights of the hot stamping machine 8. Ultimately, this results in inconsistent hot stamping depths on the packaging bag, thus affecting the final production quality of the packaging bag. In contrast, this invention uses a mechanical structure to drive the hot stamping machine 8 to lift and lower, ensuring that the lifting and lowering heights of the hot stamping machine 8 remain consistent, so that the final hot stamping depth on the packaging bag is consistent.
