Description

Technical Field

[0001] This utility model relates to the technical field of PE bag processing equipment, and in particular to a PE self-sealing bag tail sealing and cutting device. Background Technology

[0002] Dental floss picks, also known as floss picks, are products used in conjunction with a toothbrush in daily oral care. Before dental floss picks, people used dental floss to achieve the same effect. Compared to dental floss, dental floss picks are more convenient, efficient, safe, and hygienic. A toothbrush can only reach about 70% of the surface of teeth; dental floss fills this gap and is a widely used household oral care product in Europe and America. This product can be used as both a toothpick and dental floss.

[0003] After dental floss picks are produced, they need to be bagged and then sealed. The current sealing method usually involves emptying the bag and then manually trimming the waste edges. This is inefficient and can easily tear the sealed part during the trimming process, causing damage to the PE bag and affecting product quality. Utility Model Content

[0004] The purpose of this invention is to provide a PE self-sealing bag tail sealing and cutting device, which solves the technical problem of low sealing and cutting efficiency of PE bags containing dental floss in the prior art.

The advantage of this step is that it prevents the product and waste edges from adhering to the cutter, and it can also further ensure the processing quality of the product.

[0027] Furthermore, the bottom of the sealing and cutting protective plate is not higher than the bottom of the cutter. The advantage of this step is that it facilitates the sealing and cutting protective plate in preventing waste edges from adhering to the cutter.

[0028] Furthermore, the cutter has a heating tube mounting hole inside, which facilitates hot cutting.

[0029] Furthermore, the lifting and guiding assembly includes:

[0030] Multiple guide shaft supports are installed at intervals on the support frame;

[0031] Multiple lifting guide shafts are installed one-to-one on the guide shaft support, and the lifting guide shaft is equipped with the guide connecting block. The beneficial effect of this step is to ensure that the relevant components can be lifted and lowered stably.

[0038] Furthermore, guide positioning plates are provided on both sides of the sealing and cutting base, and multiple grooves are provided on the sealing and cutting base. The grooves correspond to the clamping ends of the waste clamping mechanism. The beneficial effect of this step is to facilitate the placement of PE bags.

[0039] Furthermore, the waste clamping mechanism includes:

[0040] A push cylinder, the output end of which faces the sealing and cutting base;

[0041] A gripper cylinder mounting plate is installed at the output end of the push cylinder;

[0042] Several gripper cylinders are installed on the side of the gripper cylinder mounting plate facing the sealing and cutting base. The advantage of this step is that the gripper cylinders facilitate positioning.

Therefore, they should not be construed as limiting this utility model.

[0064] In this application, unless otherwise expressly specified and limited, the terms "installation," "setup," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0065] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0066] Example 1:

[0067] like Figure 1-6As shown in the figure, this application discloses a PE self-sealing bag tail sealing and cutting device for sealing and cutting PE bags. Compared with the existing manual operation method, it is more efficient. This application integrates material pressing, sealing and cutting and waste disposal into one device, which effectively improves work efficiency.

[0068] like Figure 1 , 2 As shown, the specific structure of this application includes:

[0069] Support frame 1, which is an existing frame, includes a support plate at the top for installing other components to ensure stable operation. The upper surface of the support plate is preferably flat.

[0070] The sealing and cutting base 2 is installed on the support frame 1. The sealing and cutting base 2 is used for support, that is, the corresponding bag to be processed is placed on the sealing and cutting base 2, and the subsequent cutting blade performs cutting and processing in this area;

[0071] 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 and ensure the stability of the subsequent pressing mechanism and sealing and cutting mechanism.

[0072] 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 first, so as to avoid bulging and other phenomena during subsequent sealing and cutting, which would affect the quality of the product.

[0073] 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 remove the waste edge.

[0074] The waste clamping mechanism 6 is installed on the support frame 1, and the waste clamping mechanism 6 is located on the side of the sealing and cutting mechanism 5 away from the pressing mechanism 4. Specifically, the waste clamping and positioning and pressing are performed first to replace manual operation, and then sealing and cutting are performed. Finally, the waste edge is taken away and discarded through the waste clamping mechanism 6.

[0075] Compared with existing cutters, the sealing and cutting mechanism 5 in this application is equipped with a sealing and cutting protective plate, which is used to squeeze both sides of the cut edge to avoid wrinkling during high-temperature sealing and cutting, thereby improving product quality.

[0076] Specifically, the sealing and cutting mechanism 5 includes:

[0077] 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 drive the subsequent guide connecting block to make lifting and lowering movements. At the same time, in order to improve stability, there are two sealing and cutting lifting drive units 501 in this application, located at both ends of the sealing and cutting base 2.

[0078] The guide connecting block 502 is installed on the lifting and guiding assembly 3, specifically 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 and guiding assembly.

[0079] The tool holder 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.

[0080] The cutter 504 is installed below the cutter holder fixing plate 503 and corresponds to the sealing and cutting base 2. The cutter 504 and the cutter holder fixing plate 503 move together 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 waste edges. The cutter 504 and the cutter holder fixing plate 503 are connected by a screw, and the height limiting sleeve 510 is fitted on the screw.

[0081] At least two sealing and cutting protective plates 505 are set on both sides of the cutter 504. The sealing and cutting protective plates 505 will press down on 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 sticking to the cutter.

[0082] A plurality of pressure plate connecting rods 511 are installed between the sealing and cutting protective plates 505, and the pressure plate connecting rods 511 are spaced apart along the length direction of the sealing and cutting protective plates 505.

[0083] As mentioned above, relative movement is required between the sealing and cutting protective plate 505 and the cutter 504 in this application to achieve the pressing and sealing actions. Therefore, this application further designs the sealing and cutting mechanism 5, such as... Figure 4 As shown, it includes:

[0084] A floating stud 506 is installed on the guide connecting block 502. The floating stud 506 can float up and down, and its purpose is to drive the sealing and cutting protective plate 505 to move up and down.

[0085] The protective plate mounting block 507 is located at the bottom of the floating stud 506 and is connected to the inner wall of the sealing and cutting protective plate 505. Specifically, there is a gap between the protective plate mounting block 507 and the knife holder fixing plate 503, which facilitates the up and down movement of the sealing and cutting protective plate 505.

[0086] A compression spring 508 is fitted onto the floating stud 506, and the compression spring 508 is located between the protective plate mounting block 507 and the knife holder fixing plate 503. That is, under the action of the compression spring 508, the protective plate mounting block 507 can be moved upward by force, thereby completing the upward movement of the sealing and cutting protective plate 505.

[0087] The height limiting sleeve 510 is connected at one end to the top of the cutter 504 and at the other end to the cutter holder fixing plate 503. 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 relative movement of the sealing and cutting protective plate 505 and the cutter 504.

[0088] To further explain the sealing and cutting mechanism 5 in this application, the sealing and cutting protective plate 505 in this application consists of two pieces, spaced apart. The cutter 504 is located between the sealing and cutting protective plates 505. At this time, both 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. First, the waste clamping mechanism 6 clamps and positions the bag. Then, after the bottom of the sealing and cutting protective plate 505 contacts the product to be processed, it continues to move downward, so that the cutter contacts the bag to be processed, completing the sealing and cutting operation. The subsequent components move upward, and the waste edge is removed by the waste clamping mechanism 6.

[0089] To achieve the above functions, this application further designs the sealing and cutting protective plate 505, wherein the bottom of the sealing and cutting protective plate 505 is not higher than the bottom of the cutter 504, so as to achieve compression during sealing and cutting and avoid wrinkling.

[0090] Meanwhile, in order to ensure processing efficiency, the width of the sealing and cutting protective plate 505 is not less than the width of the cutter 504, which can also ensure sufficient width for clamping.

[0091] This application is for hot cutting, therefore the cutter 504 has a heating tube mounting hole 509 inside, and a heating tube can be inserted to complete the heating of the cutter 504.

[0092] To ensure stable movement and consistent direction of motion of the entire device, all lifting and lowering components in this application are concentrated on a single lifting and guiding assembly 3. Specifically, as shown in... Figure 2 As shown, the lifting and guiding assembly 3 includes:

[0093] Multiple guide shaft supports 301 are installed at intervals on the support frame 1. The guide shaft supports 301 are existing structures and will not be described in detail here.

[0094] Multiple lifting guide shafts 302 are installed one-to-one on the guide shaft support 301, and the guide connecting block 502 is installed on the lifting guide shaft 302.

[0095] Further explanation is given regarding the lifting guide assembly 3 in this part. There are four lifting guide shafts 302, spaced apart. The lifting guide shafts 302 are arranged in pairs, and the two sets of lifting guide shafts 302 are located at both ends of the sealing and cutting base 2. Each set of lifting guide shafts 302 is equipped with a guide connecting block 502 (there are two guide connecting blocks 502, 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 cutting knife and sealing and cutting protective plate have four points of support to complete the lifting and lowering, thereby ensuring the stability of the cutting knife during sealing and cutting.

[0096] Before processing, the bags need to be emptied, which is done through the pressing mechanism 4. Specifically, as follows: Figure 3 As shown, the pressing mechanism 4 includes:

[0097] The material clamping plate 401 is installed on the lifting guide shaft 302;

[0098] The pressure guide rod 402 is vertically installed on the pressure locking plate 401;

[0099] The pressing drive unit 403 is vertically mounted on the pressing locking plate 401. The pressing drive unit 403 can be a cylinder.

[0100] A pressing plate 404 is installed at the bottom of the pressing guide rod 402, and the top of the pressing plate 404 is connected to the bottom of the pressing guide rod 402 and the output end of the pressing drive unit 403.

[0101] The pressing sponge 405 is installed on the bottom side of the pressing fixing plate 404. The pressing fixing plate 404 moves up and down under the drive of the pressing drive unit 403 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 to perform the emptying operation.

[0102] To ensure the stability of the bags after they are placed, guide positioning plates 7 are provided on both sides of the sealing and cutting base 2. The guide positioning plates 7 have limiting grooves 8, which correspond to the bags to be processed, thus limiting their movement and preventing them from moving. The sealing and cutting base 2 has multiple grooves 9, which correspond to the clamping ends of the waste clamping mechanism 6. Multiple bags correspond to multiple grooves 9, which facilitates the stability of clamping and also improves the processing efficiency.

[0103] Specifically, such as Figure 5 As shown, the waste clamping mechanism 6 includes:

[0104] Push cylinder 601, the output end of push cylinder 601 faces the sealing and cutting base 2;

[0105] A gripper cylinder mounting plate 602 is installed at the output end of the push cylinder 601;

[0106] Several gripper cylinders 603 are installed on the side of the gripper cylinder mounting plate 602 facing the sealing and cutting base 2. The push cylinder 601 of this application pushes the gripper cylinders 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 emptying and sealing and cutting are completed, the push cylinder 601 drives the gripper cylinders 603 away from the sealing and cutting base 2, and then releases the gripper cylinders 603, thereby realizing the discarding of the waste edge.

[0107] Specifically, such as Figure 1 As shown, this application also includes a waste collection hopper 10, which is inclined and connected to the support frame 1, thus facilitating the collection and processing of waste.

[0108] Further explanation is provided regarding this application:

[0109] This application is mainly used to complete the processing of the seamless sealing and cutting of the tail of PE self-sealing bags. During operation, the PE self-sealing bag is placed on the sealing and cutting base 2. The waste material clamping mechanism 6 operates, causing the gripper cylinder 603 to clamp the waste edge of the PE self-sealing bag. Then, the pressing mechanism 4 operates, pushing the pressing sponge 405 to squeeze the PE self-sealing bag and expel the waste. Next, the sealing and cutting mechanism 5 operates, the sealing and cutting protective plate 505 presses firmly, and then the cutter 504 completes the sealing and cutting. After sealing and cutting, the gripper cylinder 603 removes the waste edge and places it into the waste bin from the waste collection hopper; thus realizing the sealing and cutting production process. This application also includes some other pneumatic control components, which are existing technologies and will not be described in detail here.
