Description

Technical Field

[0001] This utility model relates to the field of shaping machine technology, specifically to a shaping pressing mechanism and a shaping machine. Background Technology

[0002] A ton bag shaping machine is a mechanical device used to automatically shape and stack ton bags. It mainly includes a feeding device, a shaping device, a stacking device, and a control system.

[0003] Publication number CN218877811U discloses a manual and automatic integrated precipitated silica ton bag pressing and shaping machine. Before pressing and shaping the ton bag, the drive cylinder is first connected and fixed to the movable pressure plate. Then, the ton bag is placed on the surface of the base plate. The drive cylinder is controlled by the PLC controller to push the movable pressure plate down in a cycle. The movable pressure plate is guided by the cooperation of the support column and the guide column, so that the movable pressure plate can press and shape the ton bag.

[0004] However, during automated feeding, differences in the weight of goods and the type of outer bag among different batches of ton bags can easily lead to deviations in the position of the ton bags delivered to the base plate. In this patent, however, because the inner cavities of the guide column and the support column are matched, the orthogonal projection position of the movable pressure plate on the base plate is fixed, preventing the movable pressure plate from being directly aligned with different batches of ton bags, thus hindering the effective shaping of different batches of ton bags. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a shaping and pressing mechanism and a shaping machine to solve the technical problem in the prior art that, due to the matching of the inner cavities of the guide column and the support column, the orthogonal projection position of the movable pressing plate on the base plate is fixed, and the movable pressing plate cannot be aligned with different batches of ton bags, thus failing to effectively shape different batches of ton bags.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0010] A guide arm, passing through the channel and movable along the extension direction of the channel; and

[0011] The pressing part is connected to one end of the guide arm.

[0012] In some embodiments, each of the abutting portions includes an abutting member and a locking member. The abutting member is mounted on the mounting portion and is movable in a direction toward and away from the guide arm. The locking member connects the mounting portion and the abutting member, and is used to lock the abutting member to the mounting portion and to unlock the abutting member.

[0013] The abutting end is located on the side of the abutting member that is close to the opposite abutting member.

The sliding groove is provided in at least two sets, and the at least two sets of sliding grooves are located on opposite sides of the guide arm and correspond one-to-one with at least two abutting members. Each sliding groove is provided with a locking screw hole on the side away from the guide arm.

[0015] The abutting member has a slider that is slidably disposed in the groove, and the locking member includes a locking screw, one end of which is screwed into the locking screw hole and extends into the groove, pressing against the slider.

[0016] In some embodiments, two slides are provided in the same group, the two slides in the same group are located on the same side of the guide arm, and their arrangement direction intersects with the arrangement direction of the two opposing abutments;

[0017] Each of the aforementioned abutting members has two sliders, which are respectively slidably disposed in the two grooves of the same group.

[0018] In some embodiments, the abutting member includes a mounting shaft and an abutting roller. The mounting shaft is mounted on the mounting portion and can move in a direction close to and away from the guide arm. The abutting roller is rotatably mounted on the mounting shaft and rolls against the guide arm, with one end of the roller close to the guide arm being the abutting end.

[0019] The locking member connects the mounting part and the mounting shaft, and is used to lock the mounting shaft to the mounting part and to unlock the mounting shaft.

[0020] In some embodiments, the abutting member includes a plurality of abutting rollers and a plurality of mounting shafts, the plurality of abutting rollers being spaced apart along the extension direction of the channel, and the plurality of mounting shafts corresponding one-to-one with the plurality of abutting rollers.

[0021] In some embodiments, the mounting part has a mounting channel, the extending direction of the mounting channel is the same as the extending direction of the channel, and its sidewall is provided with a clearance opening communicating with the outside, and the clearance opening is provided in multiple ways along the circumference of the mounting channel.

[0022] Each of the plurality of abutting portions corresponds one-to-one with a plurality of clearance openings, and a portion of each abutting portion extends from the clearance opening into the mounting channel to form the abutting end.

This ensures that the pressing part connected to the guide arm is directly facing the material at the shaping position, and that the guide arm is always in contact with the multiple contact parts, guaranteeing stable movement of the pressing part driven by the guide arm. Thus, this mechanism not only stably guides the guide arm but also flexibly adjusts the position of the pressing part at the shaping position, ensuring that the pressing part presses directly onto the material, meeting the shaping needs of different batches of ton bags and improving practicality.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0036] To address the technical problem in existing technologies where the inner cavities of the guide column and support column are matched, resulting in a fixed orthographic projection position of the movable pressure plate on the base plate, preventing the movable pressure plate from facing different batches of ton bags and thus hindering effective shaping of ton bags from different batches, this utility model provides a shaping and pressing mechanism. This mechanism can stably guide the guide arm while flexibly adjusting the position of the pressing section at the shaping position, ensuring that the pressing section presses directly onto the material, thus meeting the shaping needs of different batches of ton bags and improving practicality.

[0037] It should be noted that the shaping and pressing mechanism described in this utility model is used in, but not limited to, shaping machines. For ease of explanation, this utility model only uses the application of the shaping and pressing mechanism in a shaping machine as an example. The principle of the shaping and pressing mechanism applied to other types of equipment is essentially the same as that applied to a shaping machine, and will not be described in detail here.

[0038] Please see Figures 1 to 4 , Figures 1 to 4 This is a schematic diagram of the shaping and pressing mechanism in one embodiment of the present invention. The shaping and pressing mechanism includes a mounting part 1, a guide arm 3, a pressing part 4, and multiple contact parts 2. The mounting part 1 has a shaping position 11 for placing materials. Multiple contact parts 2 are mounted on the mounting part 1 and surround a channel 2a. The channel 2a extends away from the shaping position 11. At least two contact parts 2 are located on opposite sides of the channel 2a and have contact ends 21 that can move relative to the mounting part 1. When moving, the contact ends 21 can approach and move away from the other contact end 21 and can maintain the position after the movement. The guide arm 3 passes through the channel 2a and can move in the direction of approaching and moving away from the shaping position 11. The pressing part 4 is connected to the end of the guide arm 3 that is close to the shaping position 11.

[0039] In the shaping and pressing mechanism provided by this utility model, a channel 2a is formed by multiple contact parts 2, and a guide arm 3 is movably inserted into the channel 2a. This allows for adjustment of the two contact parts 2 as needed. In specific operation, the two opposing contact parts 2 move synchronously in the same direction, thereby adjusting the position of the guide arm 3 in the direction of the contact parts 2's movement. This ensures that the pressing part 4 connected to the guide arm 3 is directly facing the material at the shaping position 11, and that the guide arm 3 is always in contact with the multiple contact parts 2, ensuring stable movement of the pressing part 4 driven by the guide arm 3. Thus, while stably guiding the guide arm 3, this mechanism can also flexibly adjust the position of the pressing part 4 at the shaping position 11, ensuring that the pressing part 4 is pressing directly onto the material, meeting the shaping needs of different batches of ton bags and improving practicality.

[0040] It should be noted that the mounting part 1 can be configured as a mounting base, mounting platform, or other forms. Furthermore, the pressing part 4 can be configured as a pressing seat, pressing plate, or other forms. Specifically, in this solution, the mounting part 1 is configured as a mounting bracket, and the pressing part 4 is configured as a pressing plate.

[0041] Furthermore, it should be noted that, to ensure the guide arm 3 moves within the channel 2a, a certain clearance is maintained between each contact part 2 and the guide arm 3. The contact part 2 can be configured as a hydraulic rod, an electric actuator, or other forms. When the contact part 2 is configured as a hydraulic rod or an electric actuator, the contact end 21 is the end of its telescopic rod, and a certain clearance is maintained between the contact end 21 and the guide arm 3 to ensure the guide arm 3 can move smoothly.

[0042] In one embodiment, each abutment 2 includes an abutment 22 and a locking member 23. The abutment 22 is mounted on the mounting part 1 and can move in the direction of approaching and moving away from the guide arm 3. The locking member 23 connects the mounting part 1 and the abutment 22, and is used to lock the abutment 22 to the mounting part 1 and can unlock the abutment 22. The abutment end 21 is the side of the abutment 22 that is close to the opposite abutment 22.

[0043] In this embodiment, each contact member 22 is configured to move close to and away from the guide arm 3, and the guide arm 3 is limited by the contact member 22. At the same time, the contact member 22 is locked at any position in its movement stroke by the locking member 23, so the structure is stable and reliable.

[0044] It should be noted that the locking element 23 can be configured as a pressing screw, a pin, or other forms.

[0045] In one embodiment, the mounting part 1 is provided with a slide groove 1a along the direction close to the guide arm 3. There are at least two sets of slide grooves 1a, which are located on opposite sides of the guide arm 3 and correspond one-to-one with at least two abutting members 22. Each slide groove 1a has a locking screw hole 1b on the side away from the guide arm 3. The abutting member 22 has a slider 221 that is slidably disposed in the slide groove 1a. The locking member 23 includes a locking screw 231, one end of which is screwed into the locking screw hole 1b and extends into the slide groove 1a and presses against the slider 221.

[0046] In this embodiment, the abutment 22 is slidably installed in the slide groove 1a via the slider 221, so that the abutment 22 can move in the direction of approaching and moving away from the guide arm 3. When the abutment 22 moves to the preset position, the slider 221 is limited by the locking screw 231. The structure is simple and reliable, saves costs, and is easy to operate.

[0047] In one embodiment, there are two slide grooves 1a in the same group. The two slide grooves 1a in the same group are located on the same side of the guide arm 3, and their arrangement direction intersects with the arrangement direction of the two opposing abutments 22. Each abutment 22 has two sliders 221, which are respectively slidably disposed in the two slide grooves 1a in the same group.

[0048] In this embodiment, a slider 221 is provided at both the upper and lower ends of the abutment member 22. Correspondingly, two sliding grooves 1a are provided on the mounting part 1 for each abutment member 22, making the movement of the abutment member 22 more stable. It should be noted that in this solution, each of the two sliding grooves 1a corresponding to each abutment member 22 is provided with a locking screw hole 1b, and each locking screw hole 1b is provided with a locking screw 231.

[0049] It should be noted that the contact element 22 can be configured as a contact seat, a contact plate, or other forms.

[0050] In one embodiment, the abutment member 22 includes a mounting shaft 222 and an abutment roller 223. The mounting shaft 222 is mounted on the mounting part 1 and can move in the direction of approaching and moving away from the guide arm 3. The abutment roller 223 is rotatably mounted on the mounting shaft 222 and rolls against the guide arm 3, with its abutment end 21 on the side near the guide arm 3. The locking member 23 connects the mounting part 1 and the mounting shaft 222, and is used to lock the mounting shaft 222 to the mounting part 1 and can unlock the mounting shaft 222.

[0051] In this embodiment, the contact member 22 is configured as a mounting shaft 222 and a contact roller 223, so that the guide arm 3 rolls in contact with the contact roller 223, reducing frictional resistance and making the movement of the guide arm 3 closer to and away from the mounting position smoother.

[0052] In one embodiment, the abutment member 22 includes a plurality of abutment rollers 223 and a plurality of mounting shafts 222. The plurality of abutment rollers 223 are spaced apart along the extension direction of the channel 2a, and the plurality of mounting shafts 222 correspond one-to-one with the plurality of abutment rollers 223.

[0053] In this embodiment, multiple abutment rollers 223 are spaced apart along the movement direction of the guide arm 3 to provide balanced support for the guide arm 3 and prevent the guide arm 3 from tilting during movement. Specifically, in this embodiment, each abutment member 22 includes two sets of abutment rollers 223 and a mounting shaft 222.

[0054] In one embodiment, please refer to Figure 5 and Figure 6 The mounting part 1 has a mounting channel 1c, which extends in a direction away from the shaping position 11, and its side wall is provided with a clearance opening 1d that communicates with the outside. Multiple clearance openings 1d are provided along the circumference of the mounting channel 1c. Multiple abutment parts 2 correspond one-to-one with multiple clearance openings 1d. A portion of each abutment part 2 extends into the mounting channel 1c from the clearance opening 1d to form an abutment end 21.

[0055] In this embodiment, the contact part 2 extends partially into the mounting hole 1c of the mounting part 1, that is, the channel 2a enclosed by the contact part 2 is located in the mounting hole 1c, which can guide the guide arm 3 to a certain extent through the mounting hole 1c. At the same time, it can also reduce the ingress of foreign objects between the contact part 2 and the guide arm 3.

[0056] In one embodiment, the guide arm 3 has a plurality of pressing end faces 31, and a plurality of abutting parts 2 correspond one-to-one with the plurality of pressing end faces 31, and each abutting part 2 can press against the corresponding pressing end face 31.

[0057] In this embodiment, each end face of the guide arm 3 is provided with a movable abutment portion 2, thereby allowing for flexible adjustment of the position of the guide arm 3 and further ensuring that the pressing portion 4 is directly facing the material. Specifically, in this design, the guide arm 3 is rectangular and has four pressing end faces 31. Correspondingly, there are eight sets of abutment rollers 223 and mounting shafts 222. Every four abutment rollers 223 form a channel 2a, which roll and press against the four mounting end faces of the guide arm 3 respectively, and the two channels 2a are spaced apart along the extension direction of the guide arm 3.

[0058] In one embodiment, the shaping and pressing mechanism further includes a drive unit 5, which is mounted on the mounting unit 1 and connected to the guide arm 3, for driving the guide arm 3 to move in directions toward and away from the shaping position 11.

[0059] In this embodiment, the drive unit 5 drives the guide arm 3 to move closer to and away from the mounting position, thereby improving the automation level of the mechanism. It should be noted that the drive unit 5 can be configured as a hydraulic cylinder, a pneumatic cylinder, or an electric actuator. In one embodiment, the drive unit 5 is configured as a hydraulic cylinder, with both ends of the hydraulic cylinder rotatably connected to the guide arm 3 and the mounting part 1, respectively, ensuring that it can drive the guide arm 3 to move in the direction of approaching and moving away from the mounting position. Specifically, this can be achieved through a ball joint rotatable connection.

[0060] Furthermore, this utility model also provides a shaping machine, which includes the shaping pressing mechanism described in any of the above embodiments. It should be noted that the detailed structure of the shaping pressing mechanism of the shaping machine can be referred to the embodiments of the shaping pressing mechanism described above, and will not be repeated here. Since the shaping pressing mechanism described above is used in the shaping machine of this utility model, the embodiments of the shaping machine of this utility model include all the technical solutions of all the embodiments of the shaping pressing mechanism described above, and the achieved technical effects are also completely the same, and will not be repeated here.

[0061] To better understand this utility model, the following is combined with... Figures 1 to 6 The technical solution of this utility model is described in detail below:

[0062] In this design, a channel 2a is formed by four contact rollers 223, and a guide arm 3 is movably inserted into the channel 2a, allowing adjustment of two opposing contact rollers 223 as needed. In operation, by tightening and loosening the locking screw 231, the two opposing contact rollers 223 move synchronously in the same direction, thereby adjusting the position of the guide arm 3 in the direction of the contact rollers 223's movement. This ensures that the pressing part 4 connected to the guide arm 3 is directly facing the material at the shaping position 11, and that the guide arm 3 is always in rolling contact with the multiple contact rollers 223, ensuring stable movement of the pressing part 4 driven by the guide arm 3. Thus, while stably guiding the guide arm 3, this mechanism can also flexibly adjust the position of the pressing part 4 at the shaping position 11, ensuring that the pressing part 4 is pressing directly onto the material, meeting the shaping needs of different batches of ton bags and improving practicality.
