Description

Technical Field

[0001] This utility model relates to the field of bag making machine mold mounting rack equipment, specifically to an adjustable mold mounting rack for a bag making machine. Background Technology

[0002] A bag-making machine is used to produce plastic or other material packaging bags of various sizes and thicknesses. It has a wide processing range, with plastic packaging bags as its main product. It uses frequency conversion speed regulation and computer control, allowing for precise adjustment of bag length. An electric eye tracking device ensures accurate positioning of the printed bag pattern. During operation, raw materials are fed into the machine and undergo a series of processes such as bag making, gluing, shaping, creasing, and bottom sealing, ultimately outputting finished bags. Different molds are needed to process bags of different specifications and materials. Adjusting the mold position ensures accurate bag dimensions and standardized shapes, improving production efficiency. Mold adjustment is also a key step in solving common problems such as bag wrinkles and inconsistent bag lengths.

[0003] In the existing bag-making machine mold mounting system, the method of fixing the mold with bolts or nuts is widely used and ensures the stability of the mold and the reliability of operation to a certain extent. However, its defects are becoming increasingly prominent. Specifically, this fixing method is particularly cumbersome in adjusting the position of the mold. Whenever it is necessary to adjust the mold to adapt to the production of packaging bags of different sizes or types, the operator must manually tighten or loosen the nuts of each connection part one by one. This not only consumes a lot of time and energy, but also increases the complexity of operation. In addition, during manual operation, due to human factors, such as different tightening forces, the mold may be unevenly fixed, which will affect the accuracy and efficiency of bag making. More seriously, frequent tightening and loosening of nuts can easily cause wear on nuts and bolts, shorten their service life, and increase the maintenance cost of the equipment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the aforementioned technologies by proposing an adjustable mold mounting frame for a bag-making machine, thereby solving the aforementioned technical problems.

[0005] This utility model provides an adjustable mold mounting bracket for a bag making machine, including a bag making machine frame and a mold mounting bracket disposed on the bag making machine frame, wherein the bag making machine frame is provided with a horizontal adjustment surface, and further includes:

[0006] End plate, the end plate is set on the adjustment surface of the bag making machine frame;

[0007] A connecting plate is mounted on the end plate and is slidably connected to the end plate. The connecting plate is fixedly connected to the mold mounting frame.

[0008] The longitudinal displacement adjustment component is set on the adjustment surface of the bag making machine frame and connected to the end plate. It is used to drive the end plate to move on the adjustment surface of the bag making machine frame to adjust the longitudinal position of the mold mounting frame.

[0009] A lateral displacement adjustment assembly is mounted on the end plate and connected to the connecting plate. It is used to drive the connecting plate to move along the lateral length direction of the end plate to adjust the lateral position of the mold mounting frame.

[0010] The clamping mechanism is located on the end plate and abuts against the connecting plate. The clamping mechanism is used to limit the position between the end plate and the connecting plate in order to limit and fix the mold mounting frame.

[0011] Preferably, the longitudinal displacement adjustment assembly includes a rocker arm that is disposed through the end plate. A gear is fixed to one end of the rocker arm. A rack that meshes with the gear is fixedly installed on the adjustment surface of the bag making machine frame. A longitudinal locking member that abuts against the rack is disposed through the end plate.

[0012] Preferably, the lateral displacement adjustment assembly includes a drive handle, which is disposed through the end plate and has a threaded portion. A fixing plate is disposed on the connecting plate and has a threaded hole that mates with the threaded portion on the drive handle. A lateral locking member that abuts against the drive handle is disposed through the end plate.

[0013] Preferably, the clamping mechanism includes a bolt, which is threadedly connected to the end plate. A clamping plate is provided between the bolt and the end plate, abutting against the connecting plate. The bolt and the clamping plate cooperate to limit the position of the end plate and the connecting plate.

[0014] Preferably, a limit ring is fixedly installed on the outer side of the rocker arm, with one side surface of the limit ring abutting against the end plate. The limit ring and gear on the same rocker arm are located on the left and right sides of adjacent end plates, respectively.

[0015] Preferably, thrust ball bearings are provided on both sides of the end plate, the drive handle passes through the thrust ball bearings, and a nut is threaded onto the threaded part of the drive handle, with the nut pressing against the thrust ball bearing.

[0016] Preferably, the end plate has a groove that matches the position and size of the connecting plate, and the connecting plate fits into the groove.

[0017] Compared with existing technologies, it has the following beneficial effects:

[0018] This invention provides an adjustable mold mounting frame for a bag-making machine. By introducing longitudinal and lateral displacement adjustment components, the mold mounting frame achieves precise adjustment in both horizontal and vertical directions. This design greatly simplifies the mold position adjustment process. Operators no longer need to manually tighten or loosen nuts one by one; they can easily achieve rapid mold positioning simply by adjusting the components, thus significantly improving operating efficiency and adjustment accuracy. In addition, the design of the clamping mechanism further enhances the stability of the mold mounting frame. Through the abutment between the clamping mechanism and the connecting plate, the position between the end plate and the connecting plate can be effectively limited, thereby achieving the limiting and fixing of the mold mounting frame. This design not only improves the stability of the mold during processing but also reduces production problems caused by mold loosening or displacement, ensuring the stability and consistency of product quality and reducing the risk of wear and damage caused by frequent operation. This not only reduces equipment maintenance costs but also improves the overall performance and reliability of the equipment, providing a strong guarantee for the long-term stable operation of the bag-making machine.

[0030] This section will describe in detail the specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0031] Example 1:

[0032] like Figures 1 to 9 As shown, this utility model provides an adjustable mold mounting frame 2 for a bag making machine, including a bag making machine frame 1 and a mold mounting frame 2 disposed on the bag making machine frame 1, wherein the bag making machine frame 1 is provided with a horizontal adjustment surface, and further includes:

[0033] End plate 3 is set on the adjustment surface of the bag making machine frame 1;

[0034] Connecting plate 4 is mounted on end plate 3 and slidably connected to end plate 3. Connecting plate 4 is fixedly connected to mold mounting frame 2.

[0035] The longitudinal displacement adjustment component 5 is set on the adjustment surface of the bag making machine frame 1 and is connected to the end plate 3. It is used to drive the end plate 3 to move on the adjustment surface of the bag making machine frame 1 to adjust the longitudinal position of the mold mounting frame 2.

[0036] Lateral displacement adjustment component 6 is disposed on end plate 3 and connected to connecting plate 4. It is used to drive connecting plate 4 to move along the lateral length direction of end plate 3 to adjust the lateral position of mold mounting frame 2.

[0037] The clamping mechanism 7 is disposed on the end plate 3 and abuts against the connecting plate 4. The clamping mechanism 7 is used to limit the position between the end plate 3 and the connecting plate 4 in order to limit and fix the mold mounting frame 2.

[0038] In use, when it is necessary to adjust the specific position of the mold mounting frame 2 on the bag making machine frame 1, the longitudinal displacement adjustment component 5 is driven to drive the end plate 3 to move longitudinally on the adjustment surface of the bag making machine frame 1, thereby further driving the longitudinal position of the mold mounting frame 2 on the adjustment surface of the bag making machine frame 1. At the same time, the transverse displacement adjustment component 6 is driven to drive the connecting plate 4 to move in the transverse length direction of the end plate 3, thereby further driving the transverse position of the mold mounting frame 2 in the transverse length direction of the end plate 3. After the longitudinal and transverse positions of the mold mounting frame 2 on the bag making machine frame 1 are adjusted, the clamping mechanism 7 is used to fix the end plate 3 and the connecting plate 4 in the current position of the bag making machine frame 1, thereby ensuring that the mold mounting frame 2 is fixed in the current position of the bag making machine frame 1. In order to make the connection between the end plate 3 and the connecting plate 4 more stable, two end plates 3 and two connecting plates are provided respectively, and a clamping mechanism 7 is provided at each end of the connection between the end plate 3 and the connecting plate 4.

[0039] Example 2:

[0040] like Figures 1 to 7 As shown, in conjunction with the technical solution of Embodiment 1, in this technical solution, the longitudinal displacement adjustment component 5 includes a rocker arm 51, which is disposed through the end plate 3. A gear 52 is fixed on one end of the rocker arm 51. A rack 54 that meshes with the gear 52 is fixedly installed on the adjustment surface of the bag making machine frame 1. A longitudinal locking member 53 that abuts against the rack 54 is disposed through the end plate 3. In order to make the movement of the end plate 3 more stable, there are two end plates 3. The rocker arm 51 passes through the two end plates 3. Two gears 52 that abut against the end plate 3 are fixedly installed on the rocker arm 51 in the area between the two end plates 3. The two gears 52 move longitudinally along the length direction of the rack 54 on the adjustment surface of the bag making machine frame 1. The longitudinal locking member 53 disposed through the end plate 3 is a clamping bolt. By rotating and turning the clamping bolt, the bolt 71 on the clamping bolt can be driven to abut against the side of the rack 54, thereby fixing the end plate 3 at the current position on the rack 54.

[0041] Furthermore, the lateral displacement adjustment assembly 6 includes a drive handle 61, which is disposed through the end plate 3. The drive handle 61 is provided with a threaded portion. The connecting plate 4 is provided with a fixing plate 62, which is provided with a threaded hole 63 that mates with the threaded portion on the drive handle 61. The end plate 3 is provided with a lateral locking member 64 that abuts against the drive handle 61. The drive handle 61 passes through one side of the end plate 3 and is threadedly connected to the fixing plate 62. The fixing plate 62 is provided with a threaded through hole and an internal thread. The drive handle 61 is provided with a threaded part. The internal and external threads cooperate with each other. When the drive handle 61 is rotated, the threaded part on the drive handle 61 rotates and drives the internal thread on the fixing plate 62 to move along the threaded part on the drive handle 61. The transverse locking member 64, which is provided through the end plate 3 and abuts against the drive handle 61, is a locking bolt. When the drive handle 61 moves to the appropriate position, the locking bolt is rotated and the bolt 71 of the locking bolt abuts against the side of the drive handle 61, fixing the drive handle 61 in the current position.

[0042] Furthermore, the clamping mechanism 7 includes a bolt 71, which is threadedly connected to the end plate 3. A clamping plate 72 is provided between the bolt 71 and the end plate 3, abutting against the connecting plate 4. The bolt 71 and the clamping plate 72 cooperate to limit the position of the end plate 3 and the connecting plate 4. A threaded blind hole is provided on the end plate 3, and the bolt 71 is threadedly connected to the threaded blind hole on the end plate 3. The limiting pressure plate abuts against the connecting plate 4, and the connecting plate 4 abuts against the end plate 3. Therefore, when the bolt 71 on the limiting pressure plate is rotated, as the bolt 71 gradually enters the threaded blind hole on the end plate 3, the clamping force of the bolt 71 on the limiting pressure plate gradually increases, and the limiting pressure plate further abuts against the connecting plate 4 and the end plate 3, fixing the connecting plate 4 and the end plate 3 in their current positions.

[0043] Furthermore, a limiting ring 8 is fixedly installed on the outer side of the rocker arm 51. One side surface of the limiting ring 8 abuts against the end plate 3. The limiting ring 8 and the gear 52 on the same rocker arm 51 are located on the left and right sides of the adjacent end plates 3, respectively. The limiting ring 8 is an annular ring fitted around the outer circumference of the rocker arm 51. The diameter of the limiting ring 8 is larger than the diameter of the rocker arm 51. The limiting ring 8 and the gear 52 are fixedly installed on the left and right sides of the rocker arm 51 that passes through the end plate 3, respectively. When the rocker arm 51 is pulled to the left by an unexpected force, the rocker arm 51 is restricted from moving to the left due to the obstruction of the gear 52. When the rocker arm 51 is pulled to the right by an unexpected force, the rocker arm 51 is restricted from moving to the right due to the obstruction of the limiting ring 8.

[0044] Furthermore, thrust ball bearings 9 are provided on both sides of the end plate 3. The drive handle 61 passes through the thrust ball bearings 9, and a nut 10 is threaded onto the threaded part of the drive handle 61, which abuts against the thrust ball bearing 9. The thrust ball bearing 9 consists of an inner ring, an outer ring, and balls. The drive handle 61 is fixedly installed with the inner ring. One side of the thrust ball bearing 9 abuts against the abutting part on the drive handle 61, and the other side of the thrust ball bearing 9 abuts against the nut 10 on the drive handle 61. The nut 10 presses one side of the thrust ball bearing 9 against the end plate 3, and the end plate 3 presses the other side of the thrust ball bearing 9 against the abutting part of the drive handle 61, thereby limiting the position between the drive handle 61 and the end plate 3.

[0045] Furthermore, the end plate 3 has a groove 11 that matches the position and size of the connecting plate 4, and the connecting plate 4 fits into the groove 11 with a clearance. The connecting plate 4 slides within the groove 11 on the end plate 3, which allows for easy adjustment of the specific position between the connecting plate 4 and the end plate 3.

[0046] The working principle of the adjustable mold mounting frame 2 for a bag making machine disclosed in this application is as follows:

[0047] In use, to adjust the specific position of the mold mounting frame 2 on the bag making machine frame 1, firstly, the rocker arm 51 is rotated to drive the gear 52 on the rocker arm 51 to move longitudinally along the length direction of the rack 54 on the bag making machine frame 1, thereby further moving the mold mounting frame 2 to the longitudinal position on the bag making machine frame 1. When the mold mounting frame 2 moves to the appropriate longitudinal position, the clamping bolt is rotated to drive the clamping bolt to clamp against the rack 54, thereby restricting the longitudinal position of the mold mounting frame 2 on the bag making machine frame 1. Then, the drive handle 61 is rotated, and the rotation of the drive handle 61 drives the fixed plate 62 threadedly connected to the drive handle 61 to move. The fixed plate 62 is fixedly connected to the connecting plate 4, thereby further driving the lateral movement of the connecting plate 4. The mold mounting frame 2 is fixedly connected to the connecting plate 4, which further adjusts the lateral displacement of the mold mounting frame 2 in the lateral position. After the mold mounting frame 2 moves to a suitable lateral position, another clamping bolt on the end plate 3 drives another clamping bolt to clamp the drive handle 61, thereby further restricting the position of the fixed plate 62 on the drive handle 61, and further restricting the lateral position of the connecting plate 4 and the mold mounting frame 2. After the longitudinal and lateral positions of the mold mounting frame 2 are determined, the bolt 71 threaded to the end plate 3 is rotated, driving the bolt 71 to clamp the limiting pressure plate. The limiting pressure plate clamps the connecting plate 4 and the end plate 3, thereby further fixing the position of the end plate 3 and the connecting plate, making the position of the mold mounting frame 2 on the bag making machine frame 1 more stable.

[0048] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
