Description

Technical Field

[0001] This utility model relates to the field of packaging processing technology, specifically a clamping device for packaging printing. Background Technology

[0002] In the packaging and printing industry, during the printing and processing of packaging products such as boxes, cartons, and lunch boxes, clamps are needed to position and fix the packaging products to ensure printing accuracy. Currently, the clamps widely used in the industry mostly use cylinders or electric telescopic rods as driving components, which achieve the clamping and releasing of packaging products by driving the opening and closing of the clamp's jaws.

[0003] However, existing clamping devices of this type have obvious shortcomings in practical applications: on the one hand, the opening and closing of their grippers depends entirely on the drive of cylinders or electric telescopic rods. When installing or removing packaging, workers need to hold the packaging and wait for the drive device to complete its action. The grippers can only be fully opened before the operation can be carried out, and there is a waiting time in the whole process. On the other hand, when workers hold the packaging to pick it up or put it down, they need to hold the packaging, and the grippers are prone to causing hand injuries during the movement of the grippers. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a clamping device for packaging printing, which solves the technical problems of existing packaging clamping devices, such as waiting time for picking up and putting down, low efficiency, and easy hand injury.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for packaging printing, comprising a support frame, an mounting plate fixed on the support frame, a support platform on the mounting plate, a package for mounting on the support platform, and a clamping piece mounted on the support frame, the clamping piece having a clamping force that moves toward the support platform. In use, the package is inserted into the outside of the support platform, the support platform supports the inner wall of the package, and the clamping piece is used to clamp the package inserted into the support platform.

[0006] Furthermore, the front end of the clamping piece is provided with an outwardly expanding inclined portion. When the package is inserted into the support platform, the package comes into contact with the inclined portion, driving the two clamping pieces to expand outward.

[0007] Furthermore, a roller is rotatably mounted on the clamping piece, with one side of the roller protruding from the inner wall of the clamping piece.

[0008] Furthermore, a connecting block is fixed on the outer wall of the clamping piece, the roller is rotatably connected to the connecting block, and a through groove is opened on the clamping piece corresponding to the position of the roller. The roller passes through the through groove and protrudes from the inner wall of the clamping piece on one side.

[0009] Furthermore, the clamp is hinged to the mounting plate, the clamp is rotatable about the hinge position, and a spring is installed on the clamp, the spring force of which drives the clamp to hold the packaged items on the support platform.

[0010] Furthermore, an installation shaft is mounted on the clamping piece, and an installation block is fixedly mounted on the mounting plate. The installation shaft and the installation block are rotatably connected, so that the clamping piece and the mounting plate are hinged. An installation frame is fixedly mounted on the mounting plate, and one end of the spring is fixedly connected to the installation frame, and the other end is fixedly connected to the clamping piece.

[0011] Furthermore, the mounting plate has a through groove, the rear end of the clip passes through the through groove and extends rearward, and the spring is installed at the rear of the clip.

[0012] Furthermore, the rear end of the clip is fixedly mounted on the mounting plate, and the clip is made of an elastic material.

[0013] Furthermore, it also includes a worktable, on which the support frame is mounted, and a drive device is provided on the worktable. The drive device is connected to the support frame and is used to drive the support frame to move along the worktable.

[0014] Compared with the prior art, the present invention provides a clamping device for packaging printing, which has the following advantages:

[0015] This packaging and printing clamping device, through the arrangement of a support platform and clamping plates, allows the support platform to support the inner wall of the packaging, while the clamping plates have a clamping force that moves toward the support platform. The clamping plates achieve clamping, fixing, and positioning of the packaging. Workers only need to align the opening of the packaging with the support platform and insert it directly onto the support platform. When removing the packaging, the packaging can be directly pulled off the support platform to complete the loading and unloading operation. There is no need to hold the packaging while waiting for the traditional clamps to open and close, which greatly improves the efficiency of packaging clamping and positioning, while completely avoiding the safety hazard of hand injuries.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 2-4 This utility model discloses a clamping device for packaging printing, suitable for printing and processing packaging products with open structures such as packaging boxes, packaging cartons, and lunch boxes. It can also be used for sealing, trimming, and other processing of packaging products. The clamping device includes a support frame 1, a mounting plate 2 fixedly mounted on the support frame 1, a support platform 3 fixedly mounted on the mounting plate 2, and clamping pieces 4 mounted on the mounting plate 2. The clamping pieces 4 have a clamping force that moves towards the support platform 3. The specific driving method of this clamping force will be described in detail below.

[0025] The installation method of the clamping piece 4 can be set according to specific usage requirements: First, clamping pieces 4 can be installed on both sides of the support frame 1, and the packaging products inserted on the support platform 3 can be clamped and positioned on both sides by the cooperation of the clamping pieces 4 on both sides; Second, a single clamping piece 4 can be installed on only one side of the support frame 1, and the packaging products can be clamped and positioned on one side by the cooperation of the clamping piece 4 with the side wall of the support platform 3.

[0026] The structural dimensions of the support platform 3 can be set to meet different requirements depending on the different assembly forms of the clamping pieces 4: when the clamping pieces 4 on both sides are used for clamping, the support platform 3 can be set to a thinner structure, which only needs to support the inner wall of the packaged product; when the single clamping piece 4 is used to clamp the support platform 3, the support platform 3 needs to be set to have a certain thickness to ensure that the side wall of the support platform 3 and the clamping piece 4 cooperate to clamp the packaged product.

[0027] During operation, the staff places the packaging to be printed with its opening facing the support table 3 and inserts the packaging directly into the outside of the support table 3. At this time, the support table 3 extends into the inside of the packaging and provides support to its inner wall. The mounting plate 2 can limit the insertion depth of the packaging. In the subsequent printing process, the support table 3 can provide stable support for the packaging during printing and other processing steps. At the same time, the clamping piece 4 cooperates with the clamping piece 4 on the opposite side or the side wall of the support table 3, and uses its own clamping force to stably clamp the packaging inserted on the support table 3.

[0028] like Figure 1 As shown, the packaging printing clamping device also includes a worktable 14 for processing packaging products such as sealing, trimming, and printing. A support frame 1 is mounted on the worktable 14. To meet the needs of continuous multi-station processing, a drive device 15 is configured on the worktable 14. The drive device 15 can be a linear motor or a screw transmission mechanism where a motor drives a lead screw to rotate. The drive device 15 is connected to the support frame 1. During operation, the drive device 15 can drive the support frame 1 to move smoothly along the worktable 14, thereby causing the packaging products clamped and fixed on the support table 3 to move synchronously. This enables rapid switching between different processing stations and continuous operation of multiple processing steps such as trimming, sealing, and printing on packaging products, effectively improving the production efficiency of packaging printing and other processing.

[0029] There are multiple ways to provide the clamping force of the clip 4. The following describes two specific implementation methods, but it is not excluded that other methods can be used to provide the clamping force of the clip 4.

[0030] Implementation Method 1

[0031] like Figure 2-3 As shown, the clamping piece 4 is hinged to the mounting plate 2. This hinge connection can be achieved through a mounting shaft 10, a hinge, or a hinged joint. The clamping piece 4 can rotate around the hinged position, and its clamping force is provided by the spring 9 to drive the clamping piece 4 to clamp the packaged goods on the support platform 3. The following detailed description uses the mounting shaft 10 as an example: The clamping piece 4 is provided with a mounting shaft 10, and a mounting block 11 is fixedly provided on the mounting plate 2 at a position corresponding to the mounting shaft 10. The mounting shaft 10 and the mounting block 11 are rotatably connected, achieving the hinge connection between the clamping piece 4 and the mounting plate 2. A mounting frame 12 is also fixedly provided on the mounting plate 2. One end of the spring 9 is fixedly connected to the mounting frame 12, and the other end is fixedly connected to the clamping piece 4. The spring force of the spring 9 provides the clamping force for the clamping piece 4.

[0032] like Figure 4 and 6As shown, the mounting plate 2 further includes a through slot 13, through which the rear end of the clamping piece 4 passes and extends rearward. The spring 9 is correspondingly installed at the rear of the clamping piece 4. This arrangement extends the lever arm of the clamping piece 4. According to the lever principle, while ensuring sufficient clamping force of the clamping piece 4 on the packaged goods, a spring 9 with less elasticity can be selected, which reduces the cost of selecting the spring 9 and makes the opening and closing action of the clamping piece 4 easier.

[0033] One end of the clip 4 is fixedly installed on the mounting plate 2, and the clip 4 is made of elastic material.

[0034] Implementation Method 2

[0035] The rear end of the clamping piece 4 is fixedly installed on the mounting plate 2. The clamping piece 4 is made of an elastic material with elastic deformation capability, such as rigid elastic plastic or elastic steel sheet. The clamping piece 4 obtains the clamping force toward the support platform 3 through the elastic deformation of its own material, without the need for additional drive components such as spring 9. When the packaged product is inserted into the support platform 3, the clamping piece 4 is compressed and undergoes elastic deformation. Its own elasticity directly acts on the side wall of the packaged product, achieving a stable clamping of the packaged product.

[0036] like Figure 2 and 5 As shown, the front end of the clip 4 has an outwardly expanding inclined portion 5, which serves both as a guide and a flaring function. When the package is inserted into the support platform 3, the package will come into contact with the inclined portion 5. The force of the package insertion drives the clips 4 on both sides to expand outward through the guiding effect of the inclined portion 5, making it easier for the package to be inserted into the support platform 3. At the same time, the outwardly expanding inclined portion 5 increases the insertion area of ​​the package, allowing the package to be inserted into the support platform 3 more smoothly and conveniently, effectively reducing the difficulty of inserting the package and making the insertion more efficient.

[0037] like Figure 2 and 5 As shown, a roller 6 is rotatably mounted on the clamping plate 4, with one side of the roller 6 protruding from the inner wall of the clamping plate 4. In the clamping state, the roller 6 is in direct contact with the outer wall of the packaged product; during the insertion and removal of the packaged product, the roller 6 converts the sliding friction between the clamping plate 4 and the packaged product into rolling friction, significantly reducing the frictional force during insertion and removal, making the operation of picking up and putting down the packaged product smoother and less strenuous, while also reducing frictional damage to the outer wall of the packaged product.

[0038] The specific installation method of the roller 6 is as follows: A connecting block 7 is fixedly provided on the outer wall of the clamping piece 4. The roller 6 is rotatably connected to the connecting block 7. A through groove 8 is provided on the clamping piece 4 at the position corresponding to the roller 6. The roller 6 passes through the through groove 8 and protrudes from the inner wall of the clamping piece 4 on one side. Installing the connecting block 7 on the outer wall of the clamping piece 4 can prevent the connecting block 7 from contacting the outer wall of the packaging during the insertion and removal of the packaging and thus avoid scratching it. At the same time, it ensures that the inner wall of the clamping piece 4 remains smooth without any additional protrusions.

[0039] In summary, this packaging and printing clamping device allows the operator to simply hold the package to be processed, with its opening facing the support platform 3, and insert it towards the support platform 3. During insertion, the edge of the package contacts and applies force to the inclined portion 5 at the front end of the clamping piece 4, driving the clamping piece 4 to unfold outward. As the package continues to be inserted until it is fully installed, the clamping piece 4 applies clamping force to the side wall of the package, which, together with the support platform 3 supporting the interior of the package, completes the fixing, support, and positioning of the package. The entire installation process requires only one insertion action.

[0040] After the packaging is positioned, the drive device 15 on the workbench 14 is started. The drive device 15 moves the support frame 1 and the fixed packaging along the workbench 14 until the packaging is transported to different processing stations. Then, subsequent processing steps such as printing, trimming, and sealing can be performed in sequence. After processing, when removing the packaging, simply hold the packaging and pull it outwards from the support table 3 to remove it. The whole operation is convenient and efficient.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
