Description

Technical Field

[0001] This utility model relates to the technical field of packaging paper bag production equipment, specifically to a folding device for a bag-making machine used in the production of high-barrier solid pharmaceutical packaging paper bags. Background Technology

[0002] In the production process of high-barrier solid pharmaceutical packaging paper bags, the packaging paper needs to be cut and heat-sealed by a bag-making machine, and then folded by a folding machine before being unloaded by a feeding plate. However, in the existing technology, the folded packaging paper is prone to positional deviation due to conveying deviation when conveying along the feeding plate, resulting in multiple pieces of packaging paper being stacked messily, requiring subsequent manual sorting, which increases labor costs and reduces production efficiency. At the same time, there are many air gaps between the stacked packaging papers, which makes the packaging paper occupy a large space during storage or transportation, resulting in a narrow operating space around the feeding plate, which is inconvenient for operators to carry out subsequent transportation or sorting operations. In addition, the guiding structure of the existing device cannot adjust the spacing according to the packaging paper bags of different widths, which has a narrow range of applications and cannot meet diverse production needs. Therefore, a folding device for a bag-making machine for the production of high-barrier solid pharmaceutical packaging paper bags is proposed. Utility Model Content

[0003] This utility model proposes a folding device for a bag-making machine used in the production of high-barrier solid pharmaceutical packaging paper bags. After the bag-making machine body completes the basic processing of the packaging paper, the folding machine body folds the packaging paper according to a preset trajectory. When the folded packaging paper is conveyed to the feeding plate of the folding machine, the guide plate can adjust the spacing according to the size of the packaging paper through the adjustment mechanism. During the entire movement of the packaging paper, it guides and limits the two sides of the packaging paper. This not only guides the packaging paper to the designated position, but also corrects the positional deviation caused by the conveying deviation, so that multiple pieces of packaging paper are neatly arranged in the same direction. No subsequent manual sorting is required, which effectively reduces manual processes and improves the overall production efficiency.

[0004] According to one aspect, at least one embodiment of the present invention provides a folding device for a bag-making machine used in the production of high-barrier solid pharmaceutical packaging paper bags, including a bag-making machine body, a folding machine body, and a folding machine feeding plate. The folding machine body is provided at one end of the bag-making machine body, and the folding machine feeding plate is installed on one side of the folding machine body. A guide plate is provided on one side of the folding machine feeding plate through an adjustment mechanism, and the guide plate is used to align and arrange the folded packaging paper. A compression plate is provided on the guide plate through a pressing mechanism, and the compression plate is used to press and compress the arranged packaging paper to reduce the gaps between the packaging papers.

[0005] For example, at least one embodiment of this utility model provides a folding device for a bag-making machine for producing high-barrier solid pharmaceutical packaging paper bags, which further includes: an adjustment mechanism including a moving groove, the moving groove being opened on the top of the folding machine's feeding plate, a guide plate passing through the moving groove and being fixedly connected to a transmission sleeve, a lead screw being driven inside the transmission sleeve, a motor being provided at one end of the lead screw, and the motor's transmission end being fixedly connected to the lead screw.

[0006] For example, at least one embodiment of this utility model provides a folding device for a bag-making machine for producing high-barrier solid pharmaceutical packaging paper bags, which further includes: two sets of guide plates arranged symmetrically on the folding machine feed plate, and threads on the surface of the lead screw arranged symmetrically.

[0007] For example, at least one embodiment of this utility model provides a folding device for a bag-making machine used in the production of high-barrier solid pharmaceutical packaging paper bags, which further includes: a first stabilizing groove provided above the moving groove, the first stabilizing groove being opened on the folding machine feeding plate, a guide plate passing through the first stabilizing groove and being fixedly connected to the transmission sleeve by a support rod; a stabilizing rod provided on the surface of the folding machine feeding plate, an array of second stabilizing grooves being opened on the surface of the folding machine feeding plate, the stabilizing rods passing through the second stabilizing grooves and being fixed on the guide plate, the stabilizing rods being in contact with the surface of the folding machine feeding plate.

[0008] For example, at least one embodiment of the present invention provides a folding device for a bag-making machine for producing high-barrier solid pharmaceutical packaging paper bags, which further includes: a pressing mechanism including a sliding groove, the sliding groove being opened at the end of the guide plate, a sliding sleeve being slidably connected inside the sliding groove, one end of the sliding sleeve passing through the sliding groove and fixedly connected to the compression plate, and a sliding column being movably connected to the inner wall of the other end of the sliding sleeve, the sliding column being fixedly connected to the outside of the guide plate.

[0009] For example, at least one embodiment of this utility model provides a folding device for a bag-making machine for producing high-barrier solid pharmaceutical packaging paper bags, which further includes: a spring wound around the outside of the slide column, one end of the spring being fixedly connected to the slide sleeve, and the other end of the spring being fixedly connected to the slide column.

[0010] For example, at least one embodiment of this utility model provides a folding device for a bag-making machine for producing high-barrier solid pharmaceutical packaging paper bags, which further includes: compression plates arranged symmetrically on the folding machine feeding plate, all compression plates being fixed inside each guide plate, and each set of sliding sleeves arranged symmetrically on the guide plate.

[0011] For example, at least one embodiment of this utility model provides a folding device for a bag-making machine for producing high-barrier solid pharmaceutical packaging paper bags, which further includes: each set of compression plates is fixedly connected to a pressing plate, the pressing plate is arranged in an arc shape, and a rubber pad is provided on the surface of the pressing plate.

[0012] The working principle and beneficial effects of this utility model are as follows: After the bag-making machine body completes the basic processing of the packaging paper, the folding machine body folds the packaging paper according to a preset trajectory. When the folded packaging paper is conveyed to the folding machine's unloading plate, the guide plate can adjust the spacing according to the size of the packaging paper through an adjustment mechanism. During the entire movement of the packaging paper, it guides and limits the two sides of the paper, not only guiding the packaging paper to the designated position, but also correcting the positional deviation caused by conveying deviation, so that multiple pieces of packaging paper are neatly arranged in the same direction, eliminating the need for subsequent manual sorting, effectively reducing manual processes, and improving overall production efficiency. When the packaging paper is stacked to a certain quantity on the folding machine's feed plate, the compression plate moves towards the packaging paper through the pressing mechanism, directly acting on the top of the stacked packaging paper, squeezing the air gap between the packaging paper and the adjacent paper bags, making the stacked packaging paper more compact, thereby expanding the operating space around the folding machine's feed plate, making it easier for operators to carry out subsequent transfer or sorting operations. At the same time, the adjustable design of the guide plate also allows the device to adapt to packaging paper bags of different sizes, broadening the device's applicability.

[0020] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] Refer to the instruction manual appendix Figure 1-4A folding device for a bag-making machine used in the production of high-barrier solid pharmaceutical packaging paper bags includes a bag-making machine body 1, a folding machine body 2, and a folding machine feeding plate 3. The folding machine body 2 is located at one end of the bag-making machine body 1, and the folding machine feeding plate 3 is installed on one side of the folding machine body 2. A guide plate 4 is positioned on one side of the folding machine feeding plate 3 via an adjustment mechanism and is used to align and arrange the folded packaging paper. A compression plate 14 is moved onto the guide plate 4 via a pressing mechanism and is used to press and compress the arranged packaging paper to reduce gaps. The bag-making machine body 1 first performs basic processing such as cutting and heat sealing on the high-barrier solid pharmaceutical packaging paper to form a preliminary packaging paper structure. The preliminary packaging paper is then conveyed to the folding machine body 2, where it folds the packaging paper according to a preset folding trajectory. The folded packaging paper is then folded through the folding machine body 2. The discharge end of the machine body 2 is conveyed to the folding machine's unloading plate 3, realizing the output of the folded paper after production by the equipment. During the entire process of the packaging paper moving along the folding machine's unloading plate 3, the guide plate 4 continuously guides and limits the two sides of the packaging paper, guiding the folded packaging paper strip to the designated position. At the same time, it corrects the packaging paper strip that has shifted position due to conveying deviation, ensuring that multiple packaging paper strips can be neatly arranged in the same direction, achieving a neat unloading effect, avoiding the subsequent manual sorting process of the packaging paper, and improving production efficiency. In addition, after the packaging paper is stacked to a certain quantity on the folding machine's unloading plate 3, the downward pressing action of the compression plate 14 can directly act on the top of the stacked packaging paper, effectively squeezing the air gap between the packaging paper bags and adjacent paper bags, making the stacked packaging paper more compact, thereby increasing the operating space around the folding machine's unloading plate, making it convenient for operators to carry out subsequent transfer or sorting operations.

[0022] Then, the adjustment mechanism includes a moving groove 5, which is located on top of the folding machine's feed plate 3. A guide plate 4 passes through the moving groove 5 and is fixedly connected to a transmission sleeve 6. A lead screw 7 is connected inside the transmission sleeve 6, and a motor 8 is installed at one end of the lead screw 7. The transmission end of the motor 8 is fixedly connected to the lead screw 7. The motor 8 is connected to the main power supply via a wire, which is also connected to a control switch to control the start and stop of the motor 8. When it is necessary to adjust the spacing of the guide plate 4 to accommodate different sizes of packaging paper bags, the motor 8 is started by the control switch. The transmission end drives the lead screw 7 to rotate forward or backward. During the rotation of the lead screw 7, since the transmission sleeve 6 is threadedly connected to the lead screw 7 and the guide plate 4 is limited by the moving groove 5 and cannot rotate with the lead screw 7, the transmission sleeve 6 will move along the lead screw 7 axis. When the transmission sleeve 6 moves, it drives the guide plate 4 fixedly connected to it to move synchronously, thereby adjusting the distance between the two sets of guide plates 4. This allows it to adapt to the guiding operation of paper bags of different widths and ensures that packaging paper of different specifications can be stably guided and stacked during the conveying process.

[0023] Subsequently, two sets of guide plates 4 are symmetrically arranged on the folding machine's feed plate 3, and the threads on the surface of the lead screw 7 are also symmetrically arranged. With this arrangement, when the motor 8 drives the lead screw 7 to rotate, the two transmission sleeves 6, respectively connected to the threads on both sides of the lead screw 7, will move in opposite directions along the axial direction of the lead screw 7. One transmission sleeve 6 moves closer to the midpoint of the lead screw 7, and the other transmission sleeve 6 moves further away from the midpoint of the lead screw 7. This causes the two sets of guide plates 4 to either move closer or further apart, quickly achieving the adjustment effect of the guide plate spacing. Furthermore, the moving distance of the two sets of guide plates 4 remains consistent, ensuring that after adjustment, the two sets of guide plates 4 are still symmetrically distributed with the center line of the folding machine's feed plate 3 as the axis of symmetry, guaranteeing that the guiding and aligning effect of the packaging paper is not affected by the adjustment process.

[0024] Next, a first stabilizing groove 9 is provided above the moving groove 5. The first stabilizing groove 9 is opened on the folding machine unloading plate 3. The guide plate 4 passes through the first stabilizing groove 9 and is fixedly connected to the transmission sleeve 6 through the support rod. A stabilizing rod 11 is provided on the surface of the folding machine unloading plate 3. An array of second stabilizing grooves 10 are opened on the surface of the folding machine unloading plate 3. The stabilizing rods 11 all pass through the second stabilizing grooves 10 and are fixed on the guide plate 4. The stabilizing rods 11 are in contact with the surface of the folding machine unloading plate 3. When the transmission sleeve 6 drives the guide plate 4 to move, the guide plate 4 will ensure the stability of the equipment movement through the sliding of the first stabilizing groove 9 and the support rod. When the transmission sleeve 6 drives the guide plate 4 to move, the side of the guide plate 4 will keep in contact with the inner wall of the first stabilizing groove 9 and slide along the groove wall. At the same time, the support rod will also move with the guide plate 4. Through the sliding cooperation between the first stabilizing groove 9 and the support rod, the guide plate 4 can be limited from swaying up and down or shifting left and right during the movement, thus ensuring the stability of the equipment movement.

[0025] At this time, the pressing mechanism includes a sliding groove 12, which is opened at the end of the guide plate 4. A sliding sleeve 13 is slidably connected inside the sliding groove 12. One end of the sliding sleeve 13 passes through the sliding groove 12 and is fixedly connected to the compression plate 14. A sliding column 15 is movably connected to the inner wall of the other end of the sliding sleeve 13. The sliding column 15 is fixedly connected to the outside of the guide plate 4. When it is necessary to press and compress the stacked packaging paper, the operator presses the compression plate 14 towards the packaging paper. The compression plate 14 drives the sliding sleeve 13 to slide along the axis of the sliding column 15. During the sliding process, the sliding sleeve 13 moves along the length of the sliding groove 12, so that the compression plate 14 can move towards the packaging paper inside the guide plate 4 until it contacts the surface of the packaging paper and applies pressure, thus completing the pressing and compression operation.

[0026] Next, a spring 16 is wound around the outside of the slide column 15. One end of the spring 16 is fixedly connected to the slide sleeve 13, and the other end of the spring 16 is fixedly connected to the slide column 15. When the operator presses the compression plate 14 and causes the slide sleeve 13 to slide downward along the slide column 15, the slide sleeve 13 will exert a squeezing effect on the spring 16, causing the spring 16 to undergo elastic deformation and store elastic potential energy. When the operator releases the pressure on the compression plate 14, the spring 16 returns to its original shape under the action of elastic potential energy, pushing the slide sleeve 13 to slide upward along the slide column 15. The slide sleeve 13 drives the compression plate 14 back to its initial position, thereby ensuring that the pressing mechanism can achieve repeated pressing operations, meet the pressing and compression needs of multiple batches of stacked packaging paper, and ensure the repeated use effect of the equipment.

[0027] Secondly, the compression plates 14 are symmetrically arranged on the feeding plate 3 of the folding machine, and each compression plate 14 is fixed inside the guide plate 4. Each set of sliding sleeves 13 is symmetrically arranged on the guide plate 4. With this arrangement, when the packaging paper is pressed and compressed, the two sets of compression plates 14 can apply pressure from both sides of the packaging paper to the middle, so that both sides of the packaging bag can be subjected to uniform pressure, avoiding the packaging paper from tilting due to pressure on one side, ensuring that the packaging paper can still maintain a neat stacked state after pressing, and further improving the pressing and compression effect.

[0028] Finally, each compression plate 14 is fixedly connected to a pressing plate 17. The pressing plate 17 is arc-shaped, and its surface is covered with a rubber pad. Pressing the compression plate 14 allows for pressing the pressing plate 17. This arc-shaped structure matches the curvature of the operator's fingers, making it easy for the operator to apply pressure by placing their fingers on the pressing plate 17. The rubber pad on the surface of the pressing plate 17 is attached by adhesive or vulcanization. The surface of the rubber pad has anti-slip textures, which increases the friction between the operator's fingers and the pressing plate 17, preventing slippage during pressing. By pressing the pressing plate 17 on the compression plate 14, the operator can apply force more comfortably and control the pressing pressure more easily, ensuring effective compression of the packaging paper gaps while avoiding damage to the packaging paper due to excessive force.

[0029] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
