Technical Field

[0001] The present invention relates to the technical field of PE bag processing devices, in particular to a PE bag seamless sealing and cutting machine. Background Art

[0002] Dental floss sticks, also known as dental floss picks, are used in conjunction with toothbrushes in daily oral care. Before dental floss sticks, people used dental floss to achieve the same effect. Compared to dental floss, dental floss sticks offer advantages such as greater convenience, efficiency, safety, and hygiene. Toothbrushes only reach 70% of the upper surface of teeth, while dental floss addresses this deficiency. It is a commonly used household dental care product in Europe and the United States today. This product can be used as both a toothpick and dental floss.

[0003] After the production of dental floss sticks is completed, they need to be bagged. After bagging, they need to be packaged. The existing packaging method usually involves emptying the bags. After packaging, the waste edges are manually trimmed, which is inefficient.

[0023] In this application, unless otherwise specified or limited, terms such as "installation" and "disposition" should be understood in a broad sense. For example, they can refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on specific circumstances.

[0024] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0025] Example 1: like Figure 1-6 As shown, the embodiment of the present application discloses a PE bag seamless sealing and cutting machine, which is used to complete the sealing and cutting of PE bags. Compared with the existing manual operation method, it is more efficient. The present application integrates material pressing, sealing and cutting, and waste material processing into one device, effectively improving work efficiency.

[0026] like Figure 1 、 2 As shown, the specific structure of this application includes: Support frame 1, which is an existing frame body, includes a support plate at the top for mounting subsequent components to ensure stable operation, and the upper surface of the support plate is preferably flat; The sealing and cutting base 2 is installed on the support frame 1. The sealing and cutting base 2 is used for supporting, that is, the corresponding bags to be processed are placed on the sealing and cutting base 2, and the subsequent cutter performs cutting and processing in this area; The lifting guide assembly 3 is installed on the support frame 1. The lifting guide assembly 3 is used to provide the direction of lifting movement to ensure the stability of the subsequent lifting of the pressing mechanism and the sealing and cutting mechanism; The pressing mechanism 4 is installed on the lifting guide assembly 3. The pressing mechanism 4 is preferably located on the left side of the sealing and cutting base, that is, in the direction of feeding. In this way, the internal air of the bag to be processed can be discharged through the pressing mechanism 4 to avoid bulging and other phenomena during subsequent sealing and cutting, which affects the quality of the product. The sealing and cutting mechanism 5 is installed on the lifting and guiding assembly 3, and the sealing and cutting mechanism 5 is spaced apart from the pressing mechanism 4. The sealing and cutting mechanism 5 can realize the cutting of waste edges; The waste clamping mechanism 6 is installed on the support frame 1 and is located on the side of the sealing and cutting mechanism 5 away from the pressing mechanism 4. Specifically, the waste is first clamped, positioned, and pressed to replace manual operations, and then sealed and cut. Finally, the waste is taken away and discarded by the waste clamping mechanism 6. Compared with the existing cutter, the sealing and cutting mechanism 5 in the present application is provided with a sealing and cutting protection plate for squeezing both sides of the cutting edge to avoid wrinkles during high-temperature sealing and cutting, thereby improving product quality.

[0027] Specifically, the sealing and cutting mechanism 5 includes: The sealing and cutting lifting drive unit 501 is installed on the support frame 1. Specifically, the sealing and cutting lifting drive unit 501 can be a cylinder, which is vertically arranged, that is, the piston rod end faces upward, so as to facilitate the subsequent guide connecting block to perform lifting movement. At the same time, in order to improve stability, the sealing and cutting lifting drive unit 501 in this application is two, located at both ends of the sealing and cutting base 2; The guide connecting block 502 is installed on the lifting guide assembly 3, specifically, installed at the output end of the sealing and cutting lifting drive unit 501. Driven by this component, it moves up and down along the lifting guide assembly; The knife seat fixing plate 503 is installed on the guide connecting block 502 and is connected to the guide connecting block 502 by bolts to ensure stability; The cutter 504 is installed below the knife holder fixing plate 503, and the cutter 504 corresponds to the sealing and cutting base 2. The cutter 504 and the knife holder fixing plate 503 follow and can move up and down along the lifting guide assembly 3. When the cutter 504 descends, it contacts the sealing and cutting base 2 to complete the removal of the waste edge. The cutter 504 and the knife holder fixing plate 503 are connected by a screw, and the screw is equipped with the height limiting sleeve 510; The sealing and cutting protection plate 505 is arranged outside the cutter 504. The sealing and cutting protection plate 505 presses the bag to be processed, effectively preventing the waste edge of the bag from wrinkling during sealing and cutting, and also preventing the waste edge of the bag from adhering to the cutter.

[0028] As mentioned above, relative movement is required between the sealing and cutting protection plate 505 and the cutter 504 in this application so as to achieve the pressing and sealing and cutting actions. Because this application further designs the sealing and cutting mechanism 5, such as Figure 4 As shown, it includes: A floating stud 506 is mounted on the guide connection block 502. The floating stud 506 can float up and down to drive the sealing and cutting protection plate 505 to move up and down. The protective plate mounting block 507 is disposed at the bottom of the floating stud 506 and is connected to the inner wall of the sealing and cutting protective plate 505. Specifically, a gap is left between the protective plate mounting block 507 and the knife holder fixing plate 503 to facilitate the upward and downward movement of the sealing and cutting protective plate 505. A compression spring 508 is mounted on the floating stud 506 and is located between the protective plate mounting block 507 and the knife holder fixing plate 503. Driven by the compression spring 508, the protective plate mounting block 507 is forced to move upward, thereby completing the upward movement of the sealing and cutting protective plate 505. The height limiting sleeve 510 is connected to the top of the cutter 504 at one end and to the knife holder fixing plate 503 at the other end. The height limiting sleeve 510 is used to limit the height of the cutter 504 and is a rigid connection. Specifically, it can be a bakelite height limiting sleeve, which facilitates the subsequent relative movement of the sealing and cutting protective plate 505 and the cutter 504.

[0029] With respect to the sealing and cutting mechanism 5 in the present application, further explanation is given. The sealing and cutting protective plates 505 in the present application are two pieces, which are arranged at intervals. The cutter 504 is located between the sealing and cutting protective plates 505. At this time, the two ends of the protective plate mounting block 507 are connected to the two sealing and cutting protective plates 505, so that the two sealing and cutting protective plates 505 can move synchronously. The bag is first clamped and positioned by the waste clamping mechanism 6, and then the bottom of the sealing and cutting protective plate 505 contacts the product to be processed, and then continues to move downward, so that the cutter contacts the bag to be processed, completing the sealing and cutting operation, and the subsequent components move up, and then the waste edges are taken away by the waste clamping mechanism 6.

[0030] In order to achieve the above functions, the present application further designs the sealing and cutting protection plate 505 so that the horizontal plane of the bottom of the sealing and cutting protection plate 505 is not higher than the horizontal plane of the bottom of the cutter 504, so that compression during sealing and cutting can be achieved to avoid wrinkles.

[0031] At the same time, in order to ensure processing efficiency, the width of the sealing and cutting protection plate 505 is not less than the width of the cutter 504, which can also ensure sufficient width compression.

[0032] This application is hot cutting, so a heating tube installation hole 509 is opened inside the cutter 504, and a heating tube can be inserted later to complete the heating of the cutter 504.

[0033] In order to ensure the stable movement of the entire device components and the consistency of the movement direction, the lifting movement components of the present application are all concentrated on a lifting and guiding component 3, specifically, as Figure 2 As shown, the lifting and guiding component 3 includes: A plurality of guide shaft supports 301 are installed on the support frame 1 at intervals. The guide shaft supports 301 are existing structures and will not be described in detail here. A plurality of lifting guide shafts 302 are mounted on the guide shaft support 301 in a one-to-one correspondence, and the guide connecting block 502 is mounted on the lifting guide shaft 302 .

[0034] Further explanation is given for the lifting guide assembly 3 of this part. There are four lifting guide shafts 302, which are arranged at intervals. The lifting guide shafts 302 are grouped in pairs. The two groups of lifting guide shafts 302 are located at both ends of the sealing and cutting base 2. A guide connecting block 502 is installed on each group of lifting guide shafts 302 (the guide connecting blocks 502 are two and arranged in parallel). The guide connecting block 502 is perpendicular to the sealing and cutting base 2. A knife holder fixing plate 503 is connected between the two guide connecting blocks 502. This ensures that the subsequent cutter and sealing and cutting protective plate have four-point support to complete the lifting, thereby ensuring the stability of the cutter during sealing and cutting.

[0035] Before the bags are processed, they need to be emptied, that is, emptied by the pressing mechanism 4. Specifically, Figure 3 As shown, the pressing mechanism 4 includes: The pressing and locking plate 401 is mounted on the lifting guide shaft 302; The pressing guide rod 402 is vertically mounted on the pressing locking plate 401; The pressing drive unit 403 is vertically mounted on the pressing locking plate 401. The pressing drive unit 403 may be a cylinder. The press fixing plate 404 is installed at the bottom of the press guide rod 402, and the top of the press fixing plate 404 is connected to the bottom of the press guide rod 402 and the output end of the press driving unit 403; The pressing sponge 405 is installed on the bottom side of the pressing fixing plate 404. The pressing fixing plate 404 is driven by the pressing driving unit 403 to perform a lifting movement to complete the emptying action. In order to ensure the emptying effect and to avoid damage to the product, this application uses the pressing sponge 405 for the emptying operation.

[0036] In order to ensure the stability of the bags to be processed after placement, guide positioning plates 7 are provided on both sides of the sealing and cutting base 2. Limiting grooves 8 are provided on the guide positioning plates 7. The limiting grooves 8 correspond to the bags to be processed to complete the limiting position and prevent movement; a plurality of grooves 9 are provided on the sealing and cutting base 2. The grooves 9 correspond to the clamping ends of the waste clamping mechanism 6. A plurality of bags correspond to a plurality of grooves 9, which facilitates the stability of clamping and also improves the processing efficiency.

[0037] Specifically, if Figure 5As shown, the waste clamping mechanism 6 includes: A pushing cylinder 601, wherein the output end of the pushing cylinder 601 faces the sealing and cutting base 2; The clamping cylinder mounting plate 602 is mounted on the output end of the pushing cylinder 601; A plurality of clamping cylinders 603 are installed on the side of the clamping cylinder mounting plate 602 facing the sealing and cutting base 2; the pushing cylinder 601 of the present application pushes the clamping cylinder 603 close to the sealing and cutting base 2, and then completes the clamping of the waste edge of the bag to be processed. After the emptying and sealing and cutting are completed, the pushing cylinder 601 drives the clamping cylinder 603 away from the sealing and cutting base 2, and then releases the clamping cylinder 603, thereby realizing the discarding of the waste edge.

[0038] Specifically, if Figure 1 As shown, the present application further includes a waste collection hopper 10, which is tilted and communicated with the support frame 1, so as to facilitate the collection and processing of waste edges.

[0039] Further explanation for this application: This application is mainly used to complete the processing of the seamless sealing cut at the tail of a PE self-sealing bag. During operation, the PE self-sealing bag is placed on the sealing and cutting base 2, and the waste clamping mechanism 6 is activated, so that the clamping claw cylinder 603 clamps the waste edge of the PE self-sealing bag, and then the pressing mechanism 4 is activated, pushing the pressing sponge 405 to squeeze the PE self-sealing bag for emptying; then the sealing and cutting mechanism 5 is activated, the sealing and cutting protection plate 505 is pressed tightly, and then the cutter 504 completes the sealing and cutting. After the sealing and cutting is completed, the clamping claw cylinder 603 takes away the waste edge and puts it into the waste box from the waste collection hopper, thus realizing the sealing and cutting production process. This application also includes some other components such as air circuit control, which are existing technologies and will not be described here one by one.
