Description

TECHNICAL FIELD

[0001] The utility model relates to packing bag loading technology field, concretely relates to a packing bag loading device. BACKGROUND

[0002] Packaging bags are bags used to package various items for protection, storage, transportation, display, and sale. They are typically made from plastic, paper, cloth, metal, or other synthetic materials, and the choice of material depends on the nature, weight, size, and required level of protection of the items being packaged. Packaging bags come in a variety of designs and functions to meet the needs of different items and situations.

[0003] During the production of packaging bags, the production materials may need to be replaced according to the actual specifications of the packaging bags. During the replacement process, the widths of the materials may not be consistent, which may cause deviation in the conveying process of materials of different specifications. This deviation may lead to production errors during the production of materials. Therefore, it is necessary to limit the materials during the loading process to maintain the orderliness and regularity of the loading of materials. SUMMARY

[0004] The utility model aims at providing a packaging bag loading device to solve the problem of deviation of materials during the loading process of packaging bags in the background art.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme:

[0006] A packaging bag loading device includes a cabinet body, four support legs are fixedly installed at the bottom corners of the cabinet body to support the device, a material winding structure is fixedly installed at one end of the top of the cabinet body to convey materials, a position limiting and adjusting mechanism is provided on one side of the material winding structure to limit the position of the materials, and a tension degree adjusting mechanism is fixedly installed at the other end of the top of the cabinet body to adjust the tension degree of the materials.

[0007] The position limiting and adjusting mechanism includes two mounting brackets fixedly installed on the upper surface of the cabinet body, a horizontal rod is fixedly installed between the top ends of the two mounting brackets, a rotating gear is rotatably connected in the horizontal rod, two sliding racks are meshingly connected on both sides of the rotating gear, the two sliding racks are slidingly connected in the horizontal rod, a sliding seat is fixedly installed at one end of each of the two sliding racks, the sliding seat is slidingly connected with the horizontal rod, and a matching groove is symmetrically formed in each side of the horizontal rod and slidingly connected with the sliding seat.

[0008] Using the above technical solution, in the production process of packaging bags, the roll structure feeds the production materials into the device. During the feeding process, the materials are changed according to the actual specifications of the packaging bags to be produced. Due to the change in material specifications, it is necessary to restrict the feeding process to increase the stability of the materials during the conveying process. After the materials are conveyed from the roll structure, they are conveyed to the limiting and adjusting mechanism. The movement trajectory of the materials is restricted by the limiting and adjusting mechanism to increase the smoothness of the material movement during the conveying process. Subsequently, the materials pass through the tension adjusting mechanism, where the tension of the materials is adjusted to keep the materials in a taut state, facilitating fast and stable conveying and subsequent production processing.

[0009] A further improvement of this utility model is that the limiting adjustment mechanism also includes a connecting rod fixedly installed at the bottom of the sliding seat. A limiting frame for limiting the material is fixedly installed at the bottom end of the connecting rod. The two limiting frames are fixedly connected to both ends of the guide rod, and the two ends of the guide rod are slidably connected to the two mounting frames. A pressure block for limiting the sliding of the sliding seat is slidably connected inside one of the sliding seats. A sliding rod is fixedly installed at the top end of the pressure block. A limiting spring is sleeved at the bottom end of the sliding rod, and the limiting spring is located inside the sliding seat. A pull block is fixedly installed at one end of the sliding rod through the side wall of the sliding seat.

[0010] Using the above technical solution, when the movement trajectory of the material is restricted by the limiting adjustment mechanism, the operator pulls the pressure block upwards using the pull block and sliding rod. This compresses the limiting spring. As the pressure block moves upwards, the friction between the sliding seat and the crossbar decreases, causing the sliding seat to move. As the sliding seat moves, a sliding rack fixedly mounted on it drives another sliding rack to move synchronously in the opposite direction via a rotating gear. The sliding rack is fixedly connected to the other sliding seat, thus adjusting the position between the two sliding seats and restricting the material's position. Once the sliding seat's position is determined, the pull block is released, and the limiting spring causes the pressure block to move downwards due to its elasticity. The pressure block restricts the position of the sliding seat, thereby maintaining the stability of the device.

[0011] A further improvement of this utility model is that: both ends of the limiting frame are provided with extension frames for limiting the material.

[0012] By adopting the above technical solution, the extension frames set at both ends of the limiting frame can restrict the movement of materials, thereby increasing the smoothness and stability of material conveying.

[0013] The further improvement of the utility model technical scheme lies in: the bottom end of the pressing block is fixedly installed with a rubber pad for increasing the friction between the pressing block and the cross rod.

[0014] By the above technical scheme, in the embodiment, the setting of the rubber pad at the bottom end of the pressing block can increase the friction between the pressing block and the cross rod, thereby increasing the stability of the sliding seat on the cross rod, and further increasing the operation stability of the device.

[0015] The further improvement of the utility model technical scheme lies in: the tension adjusting mechanism comprises a fixed frame fixedly installed on the top of the cabinet body, the top end of the fixed frame is rotationally connected with a mounting bracket, the mounting brackets are rotationally connected with transmission rollers, one side of the cabinet body is fixedly installed with a fixed seat, the inside of the fixed seat is rotationally connected with two transmission gears, the two transmission gears are meshingly connected, the side of the two transmission gears is transmissionally and cooperatively connected with a synchronous belt structure, the end of the two synchronous belt structures away from the transmission gears is fixedly connected with one side of the mounting bracket, the inside of the fixed seat is rotationally connected with a worm wheel, the side of the worm wheel is fixedly connected with the side of one of the transmission gears, the inside of the fixed seat is rotationally connected with a worm, the worm and the worm wheel are meshingly connected, the bottom end of the fixed seat is fixedly installed with a driving motor, the output end of the driving motor is fixedly connected with one end of the worm through the side wall of the fixed seat.

[0016] By the above technical scheme, after the conveying position of the material is adjusted by the limiting adjusting mechanism, the material is conveyed into the inside of the tension adjusting mechanism, the material is passed through the four transmission rollers in a convex shape, then the driving motor drives the worm and the worm wheel, the rotation of the transmission gears is realized through the transmission of the worm wheel and the worm, the rotation of the two synchronous belt structures is realized with the transmission of the transmission gears, the rotation of the mounting bracket and the transmission rollers is realized with the rotation of the synchronous belt structures, and the tension of the material is adjusted, so that the material is in a taut state, and the material is better conveyed.

[0017] The further improvement of the utility model technical scheme lies in: the rotation directions of the two groups of transmission rollers are symmetrically arranged.

[0018] By the above technical scheme, the symmetrically rotating transmission rollers can quickly adjust the tension of the material, and further quickly increase the tension of the material.

[0019] The further improvement of the utility model technical scheme lies in: the side of the mounting bracket is provided with a convex rod for connecting with the synchronous belt structure.

[0020] By the above technical scheme, the convex rod arranged on the side of the mounting bracket can increase the connecting and matching degree between the mounting bracket and the synchronous belt structure, and increase the connecting stability therebetween.

[0021] Due to the adoption of the above technical scheme, the present application has the following technical progress compared with the prior art:

[0022] 1、The present application can quickly complete the delivery restriction of the packaging bag material by the setting of the restriction adjustment mechanism, avoid the deviation in the delivery process, and thus avoid the production error, and can quickly complete the restriction of the two sides of the material by the setting of the bidirectional transmission structure, and thus maintain the order and stability of the material in the delivery process, and thus better deliver the material, and the bidirectional transmission mechanism can simplify the adjustment steps, facilitate the adjustment, reduce the workload, and facilitate the operation of the staff.

[0023] 2、The present application can further adjust and deliver the material by the setting of the tension adjustment mechanism in cooperation with the restriction adjustment mechanism, and can quickly adjust the tension of the material by the tension adjustment mechanism after the adjustment and restriction of the restriction adjustment mechanism are completed, so that the material is in a taut state, and thus avoid the contact between the material and the table body due to the relaxation of the material in the delivery process, and thus avoid the attachment of sundries on the surface of the material, which is not convenient for the subsequent production operation.

[0044] As Figure 5 The utility model provides a technical scheme based on embodiment 1, preferably, the tension degree adjusting mechanism 5 includes the fixed frame 19 who is symmetrically fixedly installed at the top of the cabinet 1, the top end of fixed frame 19 is rotatably connected with the mounting bracket 20, the transmission roller 21 is rotatably connected between mounting bracket 20, one side of the cabinet 1 is fixedly installed with fixed seat 22, the inside of fixed seat 22 is rotatably connected with two transmission gears 23, and the two transmission gears 23 are meshedly connected, the one side of two transmission gears 23 is all transmissionally and cooperatively connected with synchronous belt structure 24, and the one end of two synchronous belt structures 24 away from transmission gear 23 is fixedly connected with the one side of mounting bracket 20, the inside of fixed seat 22 is rotatably connected with worm wheel 25, the one side of worm wheel 25 is fixedly connected with the one side of one of transmission gears 23, the inside of fixed seat 22 is rotatably connected with worm 26, and the worm 26 is meshedly connected with worm wheel 25, the bottom end of fixed seat 22 is fixedly installed with drive motor 27, and the output end of drive motor 27 is fixedly connected with the one end of worm 26 through the side wall of fixed seat 22.

[0045] In the embodiment, after the adjusting mechanism 4 is limited to adjust the conveying position of the material, then the material is conveyed to the inside of the tension degree adjusting mechanism 5, the material is in the shape of a Chinese character from four transmission rollers 21, then the worm 26 and the worm wheel 25 are driven by the drive motor 27, and then the rotation of the transmission gear 23 is realized by the transmission of the worm wheel 25 and the worm 26, and then the rotation of the two synchronous belt structures 24 is realized by the transmission of the transmission gear 23, and then the rotation of the mounting bracket 20 and the transmission roller 21 is realized by the rotation of the synchronous belt structure 24, and then the tension degree of the material is adjusted, so that the material is in a taut state, and then the material is better conveyed.

[0050] The working principle of the packaging bag feeding device will be specifically described below.

[0051] As Figures 1-5As shown, in the production process of the packaging bag, the material feeding work of the device is carried out by the roll structure 3, and the material is replaced according to the actual production specification of the packaging bag during the feeding process. Due to the replacement of the material specification, the material needs to be limited during the feeding process to increase the stability of the material during the conveying process. After the material is conveyed out of the roll structure 3, the material is conveyed into the limiting adjustment mechanism 4. When the limiting adjustment mechanism 4 limits the movement track of the material, at this time, the worker pulls the pressing block 15 upwards by pulling the block 17 and cooperating with the sliding rod 16. At this time, the pressing block 15 will compress the limiting spring 18. With the upward movement of the pressing block 15, the friction between the sliding seat 11 and the cross rod 7 is reduced.

The sliding rack 9 is fixedly connected with the other sliding seat 11. This will cause the position between the two sliding seats 11 to be adjusted, thereby limiting the position of the material. When the position of the sliding seat 11 is determined, the pulling block 17 is loosened. The limiting spring 18 moves the pressing block 15 downwards due to the elastic force. The position of the sliding seat 11 is limited by the pressing block 15, thereby maintaining the stability of the device.

[0052] The movement track of the material is limited by the adjustment of the limiting adjustment mechanism 4 to increase the smoothness of the movement of the material during the conveying process. Subsequently, the material passes through the tension adjustment mechanism 5. The tension of the material is adjusted by the tension adjustment mechanism 5. After the conveying position of the material is adjusted by the limiting adjustment mechanism 4, the material is conveyed into the tension adjustment mechanism 5. The material is in the shape of a convex letter and passes through the four transmission rollers 21. Subsequently, the drive motor 27 drives the worm 26 and the worm gear 25, thereby realizing the rotation of the transmission gear 23 through the transmission of the worm gear 25 and the worm 26. With the transmission of the transmission gear 23, the rotation of the two synchronous belt structures 24 is realized. With the rotation of the synchronous belt structure 24, the rotation of the mounting bracket 20 and the transmission roller 21 is realized, thereby adjusting the tension of the material to make the material in a taut state, thereby better conveying the material, making the material in a taut state, and facilitating fast and stable conveying.

[0053] The above is a detailed description of the general application of the application. However, some modifications or improvements can be made on the basis of the application, which is obvious to those skilled in the art. Therefore, without departing from the spirit of the application, the modifications or improvements are within the scope of the application.
