[0002] In the field of film printing, it is often necessary to bend and shape the edges of flexible materials such as films and paper, for example, to make the sealing edge of packaging bags or the reinforcing edge of films, in order to improve the appearance and structural strength of products or meet the requirements of subsequent processes.

[0003] Currently, common shaping methods typically employ shaping molds of fixed dimensions or simple guide plates. These existing technical solutions have the following significant drawbacks: When processing materials of varying widths, fixed forming dies or guide plates cannot adjust their spacing. Changing product specifications often requires stopping the machine and replacing the entire set of dies, impacting production efficiency. Utility Model Content The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a shaping device and printing equipment to solve the technical problem that the shaping mold cannot adjust the shaping spacing in the prior art.

[0004] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: In a first aspect, this utility model provides a shaping device, comprising: frame; Two shaping blocks are provided, with a material passage gap formed between them. The feeding side of the material passage gap is funnel-shaped, and the size of one funnel-shaped end of the material passage gap gradually decreases along the feeding direction. Shaping grooves are provided on opposite sides of the two shaping blocks, with openings at both ends along the feeding direction and one opening facing the other shaping block. An adjustment component, connecting the two shaping blocks and the frame, is used to adjust the height and spacing of the two shaping blocks.

[0005] In one embodiment, the adjustment assembly includes a first guide, two first sliders, and two second guides. The first guide is connected to the frame, and the two first sliders are spaced apart. The first sliders are slidably connected to the first guide along the guide of the first guide. The two second guides are slidably connected to the two first sliders respectively, and the sliding direction of the second guides is perpendicular to the sliding direction of the first sliders. The second guides are detachably connected to the shaping block.

[0006] In one embodiment, the adjustment assembly further includes two second sliders and two third guides. The two second sliders are spaced apart and are slidably connected to the first guide along the guide of the first guide. The two third guides are slidably connected to the two second sliders respectively, and the sliding direction of the third guides is perpendicular to the sliding direction of the first slider. The third guides can be detachably connected to the shaping block.

[0007] In one embodiment, two second sliders are disposed on opposite sides of two first sliders; The adjustment assembly further includes two first screws, both of which are connected to the frame. The two first screws are respectively slidably passed through the two second sliders and are respectively threaded to the two first sliders for adjusting the distance between the two first sliders.

[0008] In one embodiment, the adjusting assembly further includes a second screw that is slidably passed through the two first sliders and threadedly connected to the two second sliders.

[0009] In one embodiment, the shaping device further includes a roller pressing assembly, which includes two extrusion rollers, both of which are rotatably connected to the frame and are disposed on the discharge side of the shaping block, with a roller pressing gap formed between the two extrusion rollers.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] To address the technical problem that the forming mold cannot adjust the forming spacing, this utility model provides a forming device and printing equipment that can adjust the forming spacing.

[0020] It should be noted that the shaping device described in this utility model is used in, but not limited to, printing equipment. For ease of explanation, this utility model only uses the application of the shaping device in printing equipment as an example. The principle of the shaping device applied to other types of equipment is essentially the same as that applied to printing equipment, and will not be described in detail here.

[0021] Please see Figure 1 , Figure 2 and Figure 6 , Figure 1 This is a schematic diagram of the structure of the shaping device in one embodiment of the present invention. The shaping device includes a frame 1, two shaping blocks 2, and an adjustment component 3. A material passage gap 2a is formed between the two shaping blocks 2. The feeding side of the material passage gap 2a is funnel-shaped, and the size of the funnel-shaped end of the material passage gap 2a gradually decreases along the feeding direction. A shaping groove 2b is provided on the opposite side of the two shaping blocks 2. The two ends of the shaping groove 2b are open along the feeding direction, and the shaping groove 2b is open on one side facing the other shaping block 2. The adjustment component 3 connects the two shaping blocks 2 and the frame 1 and is used to adjust the height and spacing of the two shaping blocks 2.

[0022] The working principle is as follows: The film to be shaped enters the material passage gap 2a between the two shaping blocks 2, and first enters the flared opening of the material passage gap 2a. The two sides of the film enter the shaping groove 2b of the shaping block 2 from the flared opening, and gradually pass through the shaping block 2. The two shaping blocks 2 have shaping grooves 2b on opposite sides. When the edge of the film enters this area, it will be gradually bent and folded by the shaping groove 2b to form the required shape, such as sealing or reinforcing edge. By adjusting the component 3, the distance between the two shaping blocks 2 can be adjusted to accommodate materials of different widths. By adjusting the height of the shaping block 2, the bending depth or pressure can be controlled.

[0023] The feeding gap 2a is funnel-shaped, which makes the material feeding smoother, facilitates the insertion of the film into the shaping groove 2b of the shaping block 2, and facilitates the gradual shaping of the film, reducing the risk of material jamming, deviation or damage.

[0024] It should be understood that the adjustment component 3 can be a lead screw and nut adjustment structure or a slider and slide rail adjustment mechanism, etc. Specifically, in one embodiment, the adjustment component 3 includes a first guide 31, two first sliders 32 and two second guides 33. The first guide 31 is connected to the frame 1. The two first sliders 32 are spaced apart and are slidably connected to the first guide 31 along the guide of the first guide 31. The two second guides 33 are slidably connected to the two first sliders 32 respectively, and the sliding direction of the second guides 33 is perpendicular to the sliding direction of the first sliders 32. The second guides 33 can be detachably connected to the shaping block 2.

[0025] Two first sliders 32 can slide along a fixed first guide 31, thereby changing the horizontal distance between the two shaping blocks 2. Each shaping block 2 is connected to a second guide 33, and the second guide 33 can slide on the corresponding first slider 32. Its direction is perpendicular to the first guide 31, and the height of each shaping block 2 can be adjusted individually.

[0026] It should be understood that the first guide component 31 can be a guide rail, guide rod, etc. Specifically, for example... Figure 2 As shown, in one embodiment, the first guide member 31 includes two first guide rods 311, four limiting pieces 312, and four first fixing screws 313. The two first guide rods 311 are parallel to each other and spaced apart. The first guide rods 311 pass through the frame 1. Among the four limiting pieces 312, each first guide rod 311 has two limiting pieces 312 at both ends. The first fixing screws 313 pass through the first guide rods 311 and are threadedly connected to the first guide rods 311. The first slider 32 and the second slider 34 are slidably sleeved on the two first guide rods 311. The second guide member 33 includes two second guide rods 331 and a first fixing block 332. The two first guide rods 311 are parallel to each other and spaced apart. One end of the two first guide rods 311 can be slidably inserted into the first slider 32. The first fixing block 332 connects the other end of the two first guide rods 311. The first fixing block 332 and the shaping block 2 can be connected by bolts or screws.

[0027] To create multiple channels for shaping the film, allowing the equipment to shape two films simultaneously, for this purpose, such as... Figure 3 As shown, in one embodiment, the adjustment component 3 further includes two second sliders 34 and two third guides 35. The two second sliders 34 are spaced apart and are slidably connected to the first guide 31 along the guide of the first guide 31. The two third guides 35 are slidably connected to the two second sliders 34 respectively, and the sliding direction of the third guides 35 is perpendicular to the sliding direction of the first slider 32. The third guides 35 can be detachably connected to the shaping block 2.

[0028] The second slider 34 can slide along the guide of the first guide 31, and the third guide 35 slides perpendicularly to the second slider 34, which can adjust the distance and height between the two shaping blocks 2. By setting the first slider 32, the second slider 34, the second guide 33 and the third guide 35, two sets of structures for shaping the film can be formed.

[0029] The third guide member 35 includes two third guide rods 351 and a second fixing block 352. The two third guide rods 351 are parallel to each other and spaced apart. One end of the two third guide rods 351 can be slidably inserted into the second slider 34. The second fixing block 352 connects the other end of the two second guide rods 351. The second fixing block 352 and the shaping block 2 can be connected by bolts or screws.

[0030] It should be understood that the second slider 34 and the first slider 32 can be manually adjusted to drive them to slide. Specifically, for example... Figure 1 and Figure 4 As shown, in one embodiment, two second sliders 34 are disposed on opposite sides of two first sliders 32. The adjusting assembly 3 also includes two first screws 36, each connected to the frame 1. The two first screws 36 are slidably passed through the two second sliders 34 and threadedly connected to the two first sliders 32, respectively, for adjusting the distance between the two first sliders 32. The first screws 36 can be rotatably connected to the frame 1, or a handle can be provided at the end of the first screw 36 located outside the frame 1, the handle being used to limit the axial movement of the first screw 36 relative to the frame 1.

[0031] By setting two first screws 36, which are threadedly connected to the first slider 32, when the first screw 36 is rotated, the first slider 32 can be driven to slide along the first guide member 31. The first screw 36 can slide through the second slider 34. When the first screw 36 rotates, it will not cause the second slider 34 to slide.

[0032] In order to fix the relative position between the two first sliders 32, for this purpose, as follows: Figure 1 and Figure 4 As shown, in one embodiment, the adjusting assembly 3 further includes a second screw 37, which is slidably passed through the two first sliders 32 and threadedly connected to the two second sliders 34. It should be understood that the second screw 37 can be rotatably connected to the frame 1, or two handles can be provided at both ends of the second screw 37, which can restrict the axial movement of the second screw.

[0033] In this embodiment, since the first slider 32 and the second screw 37 are both threadedly connected, the first slider 32 cannot slide relative to the first guide member 31 under the limitation of the second screw 37, so that the position between the two first sliders 32 is relatively fixed.

[0034] It should be understood that the two shaping blocks 2 can be connected to two first guide members 31 respectively, or to two second guide members 33 respectively, or to both first guide members 31 and second guide members 33 respectively. When different guide members are connected, the film can be shaped. The number of shaping blocks 2 can be two or four.

[0035] like Figure 1 and Figure 4 As shown, in one embodiment, the adjusting assembly 3 further includes two third screws 38 and two fourth screws 39. The two third screws 38 are correspondingly arranged with the two first sliders 32, and the third screws 38 are threadedly connected to the first sliders 32 and rotatably connected to the first fixing block 332. The two fourth screws 39 are correspondingly arranged with the two second sliders 34, and the fourth screws 39 are threadedly connected to the second sliders 34 and rotatably connected to the second fixing block 352. A handle is provided on the side of the third screws 38 and the fourth screws 39 away from the first fixing block 332.

[0036] When it is necessary to adjust the height of the first fixing block 332 and the second fixing block 352, rotate the third screw 38 and the fourth screw 39 to adjust the height of the first fixing block 332 and the second fixing block 352.

[0037] In order to set the shape of the shaped film, for this purpose, such as Figure 1 and Figure 4 As shown, in one embodiment, the shaping device further includes a roller pressing assembly 4, which includes two extrusion rollers 41. Both extrusion rollers 41 are rotatably connected to the frame 1, and the two extrusion rollers 41 are disposed on the discharge side of the shaping block 2, with a roller pressing gap formed between the two extrusion rollers 41.

[0038] After the film is initially bent by the shaping block 2, the bent part may not be completely pressed and shaped. Then the film enters the roller gap between the two extrusion rollers 41. The rotating extrusion rollers 41 roll the initially formed bent edge to make it tightly bonded and shaped.

[0039] To guide the film into the roll gap and prevent the shaped film from spreading out, therefore, as follows: Figure 5 As shown, in one embodiment, the shaping device further includes a pre-pressing component 5, which is connected to the frame 1 and disposed between the extrusion roller 41 and the shaping block 2. The pre-pressing component 5 has an abutting end for the bent edge of the material.

[0040] By setting a pre-pressing component 5, the abutting end of which is located between the extrusion roller 41 and the shaping block 2, the film can be guided into the roller gap, thus preventing the film from unfolding after shaping.

[0041] It should be understood that the pre-compression component 5 can be in the form of blocks, rods, or strips, etc., specifically, such as... Figure 5 As shown, in one embodiment, the pre-compression component 5 includes a fixing block 51 and an abutment block 52. The fixing block 51 is connected to the frame 1, and the abutment block 52 is rotatably connected to the fixing block 51 and configured to abut the bent edge of the material.

[0042] The abutting block 52 is connected to the frame 1 via the fixing block 51, thereby fixing the abutting block 52 relative to the frame 1. The abutting block 52 abuts against the film, which can guide the film to slide and prevent the film from unfolding after shaping by abutting. By rotating the abutting block 52, the position of the abutting block 52 can be adjusted so that the abutting block 52 can rotate to fit the film.

[0043] It should be understood that the abutment block 52 can be strip-shaped, rod-shaped, etc., specifically, such as Figure 5 As shown, in one embodiment, the abutment block 52 is L-shaped, with one right-angled side of the abutment block 52 connecting to the fixing block 51 and the other right-angled side abutting the film.

[0044] It should be understood that, in order to adjust the position of the abutment block 52 relative to the film in the pre-compression assembly 5, for this purpose, such as Figure 5 As shown, in one embodiment, the pre-compression assembly 5 further includes a fourth guide member 53 and a set screw 54. The fourth guide member 53 is connected to the frame 1, and its orientation is perpendicular to the material movement direction. A fixing block 51 is slidably connected to the fourth guide member 53 along its guide direction. The set screw 54 is threadedly connected to the fixing block 51, and its threaded end can abut against or disengage from the fourth guide member 53. It should be understood that the fourth guide member 53 can be a guide rod, a guide rail, etc.

[0045] When it is necessary to adjust the position of the fixing block 51 and the abutment block 52, slide the fixing block 51 so that the fixing block 51 slides along the guide of the fourth guide rod, so that the position of the fixing block 51 relative to the film can be adjusted. After adjusting to the preset position, tighten the set screw 54 to fix the fixed block 51 in the position fixed by the guide rod.

[0046] Secondly, this utility model also provides a printing device, including the above-mentioned shaping device.

[0047] The shaping device is one of the components in the film printing equipment, used to shape the film material during the printing process.
