Description

Technical Field

[0001] The present invention relates to the technical field of blister product packaging, and more specifically, to a packaging device for producing blister products. Background Art

[0002] Blister products, also known as vacuum blister or blister forming products, are a plastic processing technology that heats and softens plastic sheets and then uses vacuum suction to fit them on the mold surface to form plastic products of the desired shape. This technology is widely used in packaging, display, electronics, automobiles, furniture and other fields.

[0003] In order to improve production efficiency, most of the existing blister products are formed into trays with several groups of products of the same shape. These formed trays generally need to be stacked first, then uniformly transported to the slitting unit for slitting, and then further punched into the required shape before finally entering the sealing machine. The sealing machine is used to bond the blister products with paper cards or other materials to form a sealed package, which is the so-called heat-sealed packaging of blister products. This method makes it impossible to directly heat-seal the blister products after forming, thus reducing the efficiency of blister product packaging;

[0004] On the other hand, when slitting the tray of blister products, most of the time, a cutter is used to slit the blister products from the top of the tray. If the blister packaging object is a small package product such as stationery, this method of slitting only requires cutting the tray into several columns before entering the sealing machine for heat-sealing packaging. However, when packaging products with larger volumes, it is necessary to continue to slit each column of trays for a second time after cutting the tray into several columns, so as to cut out individual blister products. During the secondary slitting process, the individual blister products are more likely to be offset than the entire column of blister products, which causes the original shape of the blister products after the secondary slitting to be destroyed, and ultimately causes the blister products to fail to be heat-sealed normally.

[0005] At the same time, the waste generated by the punching of existing blister products generally enters the sealing machine together with the blister products to complete the heat-sealing packaging, and then the excess feed is cleaned up. And unlike the overall waste generated by cutting into a whole row of material trays, the waste generated by secondary cutting is more scattered and inconvenient to be processed uniformly. At the same time, in actual use, this treatment method will have a certain probability of adhesion between the waste and the blister products during the heat-sealing packaging process due to the small distance between the waste and the blister products, resulting in the heat-sealing packaging effect of the blister products failing to meet production requirements. Summary of the invention

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a packaging equipment for blister product production, which can directly perform secondary cutting on blister products after molding to improve packaging efficiency, position the blister products during the secondary cutting to avoid displacement caused by force, and directly perform unified adsorption treatment on waste materials after the secondary cutting is completed, so as to avoid the waste materials from sticking to the blister products during the heat-sealed packaging process and affecting the packaging effect.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0021] 1. Different from the traditional slitting from the top of the blister product tray, the slitting component slits the blister product tray horizontally from the side edge, so that during the slitting process of the blister product tray, the slitting component can also cooperate with the positioning component synchronously, and the positioning slide bar is used to limit the blister product tray, which effectively prevents the blister product tray from shifting due to the force of the slitting knife, ensuring that the shape of the blister product after slitting meets the requirements and can be heat-sealed and packaged normally.

[0022] 2. When performing secondary cutting, the secondary cutting knife is set at the bottom of the entire column of blister products, and secondary cutting is performed from the bottom.

Not only can the scattered waste be processed in a unified manner, but also the waste can be prevented from adhering to the blister product during the heat-sealing packaging process, thereby affecting the packaging effect.

[0041] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0042] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

After the blister is completed, the blister product tray is conveyed by the conveying unit 1 and arrives at the sealing and packaging unit 5 for heat sealing packaging. During the conveying process, the primary cutting unit 2 cuts the blister product tray, and the positioning punching unit 4 assists in positioning the blister product tray during the cutting process to prevent it from being offset by force.

[0045] See also Figure 1-2The conveying unit 1 includes a horizontally arranged conveyor belt assembly 12, a sealing and packaging unit 5 is arranged at one end of the conveyor belt assembly 12, and a support frame 11 is arranged at the four corners of the bottom of the conveyor belt assembly 12.

A group of conveying rollers 122 are connected to the output end of the conveying drive 121, and multiple groups of conveying belts 123 are equidistantly arranged on the conveying rollers 122. Another group of conveying rollers 122 are installed on the top of the support frame 11 close to the sealing and packaging unit 5. The connection between the two groups of conveying rollers 122 is realized by two groups of conveying belts 123. When the blister product tray is placed on the top of the conveyor belt 123 after blister molding, the conveying drive 121 drives the conveyor roller 122 to rotate, and the conveyor roller 122 rotates during the synchronous rotation of the conveyor belt 123, thereby conveying the blister product tray.

[0046] See also Figure 1-2 A loading platform 13 is provided on the top of the conveyor belt assembly 12, and the loading platform 13 is arranged inside the conveyor belt 123. Multiple groups of cutting grooves 14 are provided through the loading platform 13, and the cutting grooves 14 are arranged along the length direction of the conveyor belt assembly 12. A slitting platform 15 is provided at the bottom of the conveyor belt assembly 12, and a secondary slitting unit 3 is installed on the top of the slitting platform 15.

[0047] See also Figure 1 and Figure 3-4 The top of the conveyor belt assembly 12 is sequentially installed with a primary slitting unit 2 and a positioning punching unit 4. The primary slitting unit 2 includes two groups of slitting frames 21 symmetrically installed on both sides of the conveyor belt assembly 12. The slitting frames 21 are vertically arranged on the top of the conveyor belt assembly 12. A transverse adjustment component 22 is installed between the two groups of slitting frames 21. A longitudinal adjustment component 23 is slidably installed on the transverse adjustment component 22. A slitting component 24 is sleeved inside the longitudinal adjustment component 23. The longitudinal adjustment component 23 can slide along the direction of the transverse adjustment component 22, and can also drive the slitting component 24 to slide along the vertical direction, thereby adjusting the position of the slitting component 24, so that the slitting component 24 can slid the blister product tray.

[0048] See also Figure 1 and Figure 3-4The transverse adjustment assembly 22 includes a transverse slide bar 221 disposed between two groups of slitting frames 21. The transverse slide bar 221 is disposed in the horizontal direction and one end of the transverse slide bar 221 is connected to a transverse drive 222, which is mounted on the side wall of the slitting frame 21. The longitudinal adjustment assembly 23 includes a connecting block 231 sleeved on the transverse slide bar 221, and the internal shape of the connecting block 231 is adapted to the shape of the transverse slide bar 221. The transverse drive 222 drives the transverse slide bar 221 to rotate, and can synchronously drive the connecting block 231 to adjust the position relative to the transverse slide bar 221. A longitudinal drive 232 is installed on the top of the connecting block 231, and the slitting assembly 24 is slidably connected to the side of the connecting block 231 away from the transverse slide bar 221. The longitudinal drive 232 can drive the slitting assembly 24 to slide relative to the connecting block 231 in the vertical direction, thereby adjusting the position of the slitting assembly 24. The slitting assembly 24 is provided with a slitting drive 241 at the top and a slitting lift rod 242 that can slide in the vertical direction at the bottom, and a slitting knife 243 is connected to the bottom of the slitting lift rod 242. The slitting drive 241 can drive the slitting lift rod 242 to slide in the vertical direction, thereby fine-tuning the position of the slitting knife 243, so that the slitting knife 243 can slitting the blister product tray.

[0049] Specifically, after the blister product tray is blister-formed, it is placed on the top of the conveyor belt assembly 12. After the conveyor belt assembly 12 conveys it to the bottom of the primary slitting unit 2, the longitudinal drive 232 drives the slitting assembly 24 to slide relative to the connecting block 231 in the vertical direction, thereby adjusting the position of the slitting assembly 24, and further drives the slitting lifting rod 242 to slide in the vertical direction through the slitting drive 241, thereby fine-tuning the position of the slitting knife 243, and finally making the slitting knife 243 contact the position where the blister product tray needs to be cut. Then, the lateral slide bar 221 is driven to rotate by the lateral drive 222, and the connecting block 231 is synchronously driven to adjust the position relative to the lateral slide bar 221, so that the slitting knife 243 slides in the horizontal direction. During the sliding process of the slitting knife 243, the slitting of the blister product tray can be completed, so that it forms a whole row of blister products.

[0050] See also Figure 1 and Figure 7-10The positioning punching unit 4 includes two groups of positioning frame assemblies 41 symmetrically installed on both sides of the conveyor belt assembly 12, and a positioning bar assembly 42 is slidably installed between the two groups of positioning frame assemblies 41, and a positioning assembly 43 is installed at the bottom of the positioning bar assembly 42. The positioning frame assembly 41 includes two groups of positioning mounting frames 411 arranged vertically on the top of the conveyor belt assembly 12, and the positioning mounting frame 411 is provided with a positioning slide rail 412 along the vertical direction on the side wall of the side near the center of the conveyor belt assembly 12. The positioning bar assembly 42 includes a positioning connecting plate 423 installed between the two groups of positioning slide rails 412, and a positioning frame 421 is installed on the top of the positioning connecting plate 423. The bottoms of both ends of the positioning frame 421 are connected to the top of the positioning mounting frame 411, and a positioning drive 422 is installed on the top. The positioning drive 422 is arranged through the positioning frame 421, and its output end is connected to the positioning connecting plate 423. A positioning bar 424 is connected to the bottom of the positioning connecting plate 423, and a plurality of groups of positioning assemblies 43 are equidistantly arranged at the bottom of the positioning bar 424. The positioning drive 422 can drive the positioning connecting plate 423 to slide along the direction of the positioning slide rail 412, thereby synchronously driving the positioning bar 424 and several groups of positioning components 43 at its bottom to move in the vertical direction, so that the positioning component 43 abuts against the blister product tray, making it easier for the positioning component 43 to limit the blister product tray.

[0051] See also Figure 1 and Figure 7-10 Each group of positioning components 43 includes a mounting plate 431 installed at the bottom of the positioning strip 424, and the mounting plate 431 is used to realize the connection between the positioning components 43 and the positioning strip 424. A group of adsorption positioning modules 432 are installed at the four corners of the mounting plate 431. The four groups of adsorption positioning modules 432 are arranged through the mounting plate 431, and can abut against it from the bottom of the blister product tray to prevent it from being displaced by force during the slitting process. Each group of adsorption positioning modules 432 includes a mounting rod 4321 connected to the mounting plate 431, the mounting rod 4321 is arranged through the mounting plate 431, and a positioning slide bar 4322 is slidably installed on the inner wall of the bottom of the mounting rod 4321, and a suction cup slide bar 4323 is slidably installed on the outer wall of the bottom of the mounting rod 4321, and a disc-structured adsorption disc 4324 is installed at the bottom of the suction cup slide bar 4323. A driving member is arranged inside the mounting rod 4321, which can respectively drive the positioning slide bar 4322 and the suction cup slide bar 4323 to slide relative to the bottom of the mounting rod 4321.

[0052] Specifically, before the blister product tray is cut, after the conveyor belt assembly 12 conveys the blister product tray to the primary cutting unit 2, the positioning slide bars 4322 at the four corners of the mounting plate 431 are synchronously slid relative to the bottom of the mounting bar 4321, and the positioning slide bars 4322 are kept lower than the adsorption plate 4324. The positioning drive 422 drives the positioning connecting plate 423 to slide along the direction of the positioning slide rail 412, and synchronously drives the positioning bar 424 and several groups of positioning components 43 at the bottom thereof to move in the vertical direction, so that the positioning slide bars 4322 at the bottom of the positioning components 43 are in contact with the blister product tray. During the cutting process, the positioning slide bars 4322 at the bottom of the positioning components 43 can limit the blister product tray from the four corners of the blister product, thereby effectively preventing the blister product tray from being displaced by the force of the slitting knife 243, resulting in the destruction of the original shape of the blister product, and ultimately causing the blister product to fail to be heat-sealed and packaged normally.

[0053] Different from the traditional cutting from the top of the blister product tray, the cutting component 24 cuts the blister product tray in the horizontal direction from the side edge, so that during the process of the cutting component 24 cutting the blister product tray, it can also cooperate with the positioning component 43, and use the positioning slide bar 4322 to limit the blister product tray, effectively avoiding the displacement of the blister product tray due to the force of the cutting knife 243, ensuring that the shape of the blister product after cutting meets the requirements and can be heat-sealed and packaged normally.

[0054] See also Figure 1 and Fig.12 , a sealing and packaging unit 5 is provided at one end of the conveyor belt assembly 12, and the cut blister products can be transported to the sealing and packaging unit 5 through the conveyor belt assembly 12 for heat-sealing packaging. The sealing and packaging unit 5 includes a loading turntable 51 abutting against the conveyor belt assembly 12, and the cut blister products can enter the loading turntable 51 after falling from the conveyor belt assembly 12. The loading turntable 51 is set as a disc structure, and a driving member is arranged inside it, which can drive the loading turntable 51 to rotate. The side wall of the loading turntable 51 is sequentially surrounded by a first material taking component 52, a sealing component 54 and a second material taking component 53. The rotation of the loading turntable 51 can drive the blister product line placed on the top thereof to the first material taking component 52, and after the product to be packaged is placed inside the blister product; the loading turntable 51 continues to rotate to make the blister product reach the second material taking component 53, and the paper card to be packaged is placed on the top of the blister product; finally, the blister product is transported to the sealing component 54 for heat-sealing packaging.

[0055] See also Figure 1 and Fig.12The first material picking component 52 includes a first material picking rack 521 arranged horizontally and a first material picking suction cup 522 installed on the first material picking rack 521. The first material picking suction cup 522 can absorb the product to be packaged and put it into the blister product. The second material picking component 53 includes a second material picking rack 531 arranged horizontally and a second material picking suction cup 532 installed on the second material picking rack 531. The second material picking suction cup 532 can absorb the paper card and put it on the top of the blister product. The sealing component 54 includes a sealing rack 541 arranged horizontally. The upper sealing member 543 and the lower sealing member 544 are symmetrically arranged inside the sealing rack 541. A sealing drive 542 is arranged on the top of the upper sealing member 543. When performing heat-sealing packaging, the blister product can be placed on the lower sealing member 544, and the upper sealing member 543 is driven by the sealing drive 542 to approach the lower sealing member 544 for heat-sealing packaging.

[0056] For example 2, please refer to Figure 2 and Figure 5-6 , the second embodiment of the present invention makes the following improvements on the basis of the first embodiment. Although the cooperation between the slitting component 24 and the positioning component 43 can limit the position of the blister product tray in the process of slitting the blister product tray into a whole row of blister products, it is effectively prevented that the blister product tray is displaced by the force of the slitting knife 243, and the shape of the blister product after slitting is ensured to meet the requirements and can be heat-sealed and packaged normally. However, when packaging products with larger volumes, it is necessary to continue to perform secondary slitting on the whole row of blister products on the basis of slitting the tray into several rows, so as to cut out individual blister products. During the secondary slitting process, individual blister products are more likely to be offset by force than the whole row of blister products. Therefore, it is necessary to set a secondary slitting unit 3, which cooperates with the positioning component 43 to perform secondary slitting on the whole row of blister products without interfering with the slitting component 24 and the positioning component 43.

[0057] See also Figure 2 and Figure 5-6 A secondary slitting unit 3 is installed on the top of the slitting platform 15. The secondary slitting unit 3 includes a slitting slide assembly 31 installed on the top of the slitting platform 15 and multiple groups of secondary slitting assemblies 32 arranged on the top of the slitting slide assembly 31. The position of each group of secondary slitting assemblies 32 corresponds to the position of the slitting groove 14. Each group of secondary slitting assemblies 32 can pass through the slitting groove 14 to perform secondary slitting on the entire column of blister products placed on the top of the conveyor belt assembly 12 to form individual blister products.

[0058] See also Figure 2 and Figure 5-6The slitting slide assembly 31 includes symmetrically arranged slitting rails 311, which are mounted on the top of the slitting platform 15 and arranged along the length direction of the conveyor belt assembly 12. A slitting mounting plate 312 is mounted on the top of the slitting slide rail 311, and a secondary slitting frame 314 is mounted on the top of the slitting platform 15 near the sealing and packaging unit 5. A slitting cylinder 313 is mounted on the secondary slitting frame 314, and the slitting cylinder 313 is mounted on the top of the slitting mounting plate 312. Multiple groups of secondary slitting assemblies 32 are mounted on the top of the slitting mounting plate 312. The slitting cylinder 313 can be extended and retracted to drive the slitting mounting plate 312 to slide along the slitting rail 311, thereby synchronously driving the secondary slitting assembly 32 to move for secondary slitting.

[0059] See also Figure 2 and Figure 5-6 Each secondary slitting assembly 32 includes a secondary slitting platform 321 mounted on the top of the slitting mounting plate 312, and a secondary slitting motor 322 is mounted on one end of the secondary slitting platform 321. A slitting pulley 323 is connected to the output end of the secondary slitting motor 322, and a positioning connecting plate 423 is mounted on the other end of the secondary slitting platform 321, and a slitting pulley 323 is connected to the positioning connecting plate 423. A secondary slitting knife 325 with an arc structure is arranged on the slitting transmission block 324, and the secondary slitting motor 322 can drive the secondary slitting knife 325 mounted on the slitting transmission block 324 to rotate through the slitting pulley 323, and the secondary slitting knife 325 can complete the secondary slitting of the entire column of blister products during the rotation process.

[0060] Specifically, during the secondary slitting, the positioning slide bar 4322 is kept lower than the adsorption disk 4324, so as to limit the positions of the entire column of blister products that need to be slid. Then, each group of secondary slitting motors 322 drives the secondary slitting cutter 325 installed on the slitting transmission block 324 to rotate through the slitting pulley 323. During the rotation of the secondary slitting cutter 325, the secondary slitting cutter 325 passes through the cutting grooves 14 of each group, and the entire column of blister products is secondary slitting into separate blister products. During the secondary slitting process, the positioning slide bar 4322 can limit the blister product tray from the four corners of the entire column of blister products, so as to effectively prevent the blister product tray from being displaced by the force of the secondary slitting cutter 325, resulting in the destruction of the original shape of the blister product, and finally causing the blister product to fail to be normally heat-sealed and packaged.

[0061] When performing secondary cutting, the secondary cutting knife 325 is set at the bottom of the entire row of blister products, and they are cut for the second time from the bottom. During the process of the secondary cutting component 32 cutting the blister product tray, it can also cooperate with the positioning component 43 synchronously, and use the positioning slide bar 4322 to limit the entire row of blister products, effectively preventing the entire row of blister products from being displaced by the force of the secondary cutting knife 325, ensuring that the shape of the blister products after cutting meets the requirements and can be heat-sealed and packaged normally.

[0062] For example 3, please refer to Figure 8 and Fig.11 , the third embodiment is improved on the basis of the second embodiment as follows: although the cooperation between the secondary cutting component 32 and the positioning component 43 can limit the position of the entire row of blister products during the secondary cutting process, effectively avoiding the displacement of the entire row of blister products due to the force of the secondary cutting knife 325, ensuring that the shape of the blister products after cutting meets the requirements and can be heat-sealed and packaged normally. However, the blister products still need to be punched before heat-sealing and packaging. If the waste generated by punching is not processed, it will adhere to the blister products during the heat-sealing and packaging process, affecting the packaging effect. At the same time, the waste generated by the secondary cutting is dispersed and not connected to each other, which is not convenient for overall processing.

[0063] See also Figure 8 and Fig.11 A group of punching modules 433 are installed at the center of the bottom of the mounting plate 431. The punching module 433 includes a punching drive block 4331 installed at the bottom of the mounting plate 431. A punching connection plate 4332 is connected to the bottom of the punching drive block 4331, and an annular punching knife 4333 is connected to the bottom of the punching connection plate 4332. The annular punching knife 4333 is set as a hollow structure, and its shape is adapted to the shape of the punching connection plate 4332. When punching, the punching drive block 4331 can synchronously drive the punching connection plate 4332 and the annular punching knife 4333 to move downward synchronously, so as to punch a separate blister product using the shape of the annular punching knife 4333.

[0064] After the punching is completed, the positioning slide bars 4322 of each group at the four corners of the mounting plate 431 slide upwards synchronously relative to the bottom of the mounting rod 4321, and the suction cup slide bars 4323 of each group slide downwards synchronously relative to the bottom of the mounting rod 4321, so that the suction cup 4324 remains lower than the positioning slide bars 4322. Then, the suction cups 4324 on each group of suction positioning modules 432 are used to uniformly absorb the waste after punching of each group of individual blister products.

[0065] By sliding and switching between the positioning slide bar 4322 and the adsorption plate 4324, after the punching of individual blister products is completed, the adsorption plates 4324 on each group of adsorption positioning modules 432 can be used to adsorb the waste after the punching of each group of individual blister products. Not only can the scattered waste be processed in a unified manner, but also the waste can be prevented from adhering to the blister products during the heat-sealing packaging process, thereby affecting the packaging effect.

[0066] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
