Description

Technical Field

[0001] The utility model relates to the technical field of bag processing, and particularly relates to a base material roll pretreatment device for a bag forming machine. Background Art

[0002] Packaging bags are essential items in people's daily lives and are often used to hold other items. They are widely used because of their advantages of low cost, extremely light weight, large capacity, and convenient storage. With the development of science and technology, in order to reduce environmental pollution and achieve the purpose of environmental protection, non-woven bags have been designed. Non-woven bags, also known as non-woven fabric bags, are green products and are famous for their characteristics of toughness, durability, beauty, good air permeability, reusability, and washability. They are made of non-woven fabric, which is a new generation of environmental protection material with characteristics such as moisture resistance, air permeability, flexibility, light weight, non-flammability, easy decomposition, non-toxic and non-irritating, rich colors, and low price. Non-woven bags can decompose naturally outdoors, while indoors they can maintain a long lifespan. When burned, they are non-toxic, odorless, and do not leave any harmful residues, so they do not pollute the environment.

[0003] For the processing of non-woven bags, it is mostly processed by a bag forming machine, and a fabric pretreatment device is arranged at its front end. The fabric pretreatment device is used for the feeding and pretreatment of fabric rolls, such as hemming, gluing, etc. In order to ensure that the cut non-woven fabric sheets reach the forming device without deviation, the position of the fabric pretreatment device needs to be adjusted at the beginning, and at the same time, it is necessary to ensure that the center of the continuous fabric is aligned with the center of the forming device for accurate feeding. However, in the actual production process, during the unwinding process, the fabric may shift in the horizontal left-right direction, resulting in the fabric not being aligned and fed into the forming assembly, affecting the quality of subsequent paper bag forming.

[0004] In the prior art, a deviation correction sensor is usually arranged on the feeding roller of the bag forming machine to detect the position of the fabric. When the fabric position deviates, the fabric is corrected by moving the conveying roller. This setting method corrects the fabric to the correct position by changing the position of the fabric on the conveying roller in the horizontal direction; however, in this setting method, during the production process, when the thickness of the fabric roll changes or after correcting the position of the fabric on the conveying roller, there is an angular difference between the fabric and the fabric roll, and the fabric is very likely to run off again and needs to be calibrated, and the deviation correction frequency is relatively high, resulting in a relatively high defective rate of the produced products.

[0005] Therefore, the fabric pretreatment device of the bag forming machine in the prior art has problems of high deviation correction frequency and high defective rate of the produced products during feeding. Summary of the Utility Model

[0006] The utility model aims to solve the problems of high deviation correction frequency and high defective rate of produced products in a cloth pretreatment device of a bag forming machine in the prior art during material feeding.

[0007] To solve the above problems, the utility model provides a base material roll preprocessing device for a bag forming machine, comprising: a frame, on which a base material supplying station and a preprocessing station are sequentially arranged along the conveying direction of the base material; a base material supplying mechanism, which is arranged on the frame at the base material supplying station, and the base material supplying mechanism includes a supporting assembly and a position adjusting assembly.

[0008] Furthermore, a support assembly is arranged at the upstream end of the frame along the conveying direction of the base material and supports the base material roll, including a support component for supporting the base material roll, an intermediate connecting component connecting the support component to the position adjustment component, and a first driving component; and the position adjustment component is arranged at the downstream side of the support component in the conveying direction of the base material, including a base movably arranged on the frame base, an adjustment mechanism arranged on the base, and a second driving component arranged on the frame; the support component is connected to the adjustment mechanism through the intermediate connecting component and extends outward from the front end of the frame.

[0009] Furthermore, a first driving component is installed at one end of the intermediate connecting component and is transmission-connected to the supporting component for driving the supporting component to rotate. The supporting component is rotatably arranged at one end of the intermediate connecting component, and the other end of the intermediate connecting component is connected to the adjusting mechanism. The adjusting mechanism can drive the intermediate connecting component to rotate relative to the base, and further link the supporting component to move; the second driving component drives the base to translate relative to the frame along the width direction of the frame, and further links the adjusting mechanism and the supporting assembly to translate along the width direction of the frame; and the pre-processing station is provided with a base material pre-processing mechanism, which can pre-process the edge of the base material, and the pre-processing includes at least one of folding, heat sealing, and gluing.

[0010] By adopting the above technical scheme, when processing non-woven bags, the base material roll is placed on the supporting component, and the adjusting mechanism is used to drive the intermediate connecting component to rotate relative to the base, and further link the supporting component to move, so as to adjust the position of the base material roll in the vertical direction. On the one hand, the base material roll is flush with the conveying plane of the base material in the height direction; on the other hand, the tensioning force between the base material roll and the adjusting mechanism can be adjusted, which reduces the risk of the base material being broken during the conveying process due to excessive tensioning force during conveying, and reduces the degree of wear of the base material during conveying; and then the base is driven by the second driving component to translate relative to the frame in the width direction of the frame, and the adjusting mechanism and the supporting assembly are further linked to translate in the width direction of the frame, so as to adjust the two ends of the base material roll on the supporting component and the conveying plane of the base material to be aligned with each other in the width direction of the frame.

[0011] Furthermore, the position of the base material roll is adjusted by the aforementioned two methods. Then, the support component is driven to rotate by the first driving component, and the base material roll is gradually unwound. The base material is conveyed in the conveying plane along the conveying direction of the base material, ensuring that the base material can accurately enter the base material pretreatment mechanism without position deviation. Therefore, after the base material is conveyed to the pretreatment mechanism, the base material can be accurately pretreated, such as hemming, heat sealing, gluing, etc.

[0012] Furthermore, when the base material roll pretreatment device of the bag forming machine is conveying the base material and the position of the base material deviates, such as when the base material runs off due to the shaking of the device or the thinning of the base material roll thickness, the position of the base material is adjusted by the aforementioned two adjustment methods, so that the base material roll and the conveyed base material are translated simultaneously along the width direction of the machine frame and the positions of the base material roll and the base material in the vertical direction are changed simultaneously. Furthermore, there is no angular difference between the base material roll and the conveyed base material. It has the advantages of low rectification frequency and high rectification accuracy, and reduces the defective rate of the produced products.

[0013] In summary, the base material roll pretreatment device of the bag forming machine can adjust the tension between the base material roll and the adjustment mechanism, reducing the risk of breaking the base material during conveying due to excessive tension and reducing the wear degree of the base material during conveying; reducing the rectification frequency of the base material during conveying, enabling the base material to be accurately pretreated, such as hemming, heat sealing, gluing, etc., after being conveyed to the pretreatment mechanism, thereby reducing the defective rate of the produced products, and there is no angular difference between the base material roll and the conveyed base material, with the advantages of low rectification frequency and high rectification accuracy.

[0014] According to the base material roll pretreatment device of the bag forming machine provided by the present invention, the intermediate connecting component extends obliquely upward from the rear end of the machine frame; and the support assembly further includes a limiting component. The limiting component is arranged at the other end of the intermediate connecting component, and the limiting component and the support component are located on the same side of the intermediate connecting component for limiting the base material roll.

[0015] Furthermore, the position adjustment component further includes a lifting component that can move in the vertical direction. One end of the lifting component is installed on the base, and the other end is connected to the intermediate connecting component for supporting the support assembly and adjusting the position of the support assembly in the vertical direction.

[0016] By adopting the above technical solution, on the one hand, the limiting component can limit the base material roll located on the support component to prevent the base material roll from loosening; on the other hand, by measuring the distance between the support component and the limiting component, the thickness dimension of the base material roll can be determined, avoiding abutting against the position adjustment component due to the excessive thickness of the base material roll, thereby affecting the conveying of the base material.

[0017] Furthermore, by providing a lifting member, on the one hand, it can support the support assembly, preventing the intermediate connecting member from rotating and falling back relative to the base due to the excessive weight of the base material roll on the support member, thus improving the reliability of the base material roll pretreatment device of the bag forming machine; on the other hand, by providing a lifting member to provide assistance for the intermediate connecting member to rotate relative to the base, the reliability of the base material roll pretreatment device of the bag forming machine during use is also higher.

[0018] According to the base material roll pretreatment device of the bag forming machine provided by the present utility model, the adjusting mechanism includes a driving roller, a driving member and a supporting member. The supporting member is vertically extended and arranged on the base. The driving roller is rotatably connected to the end of the supporting member away from the base, and the other end of the intermediate connecting member is drivingly connected to the end of the driving roller; the driving member is installed on the supporting member, and the driving end of the driving member is drivingly connected to the driving roller; the driving member drives the driving roller to rotate relative to the supporting member, drives the intermediate connecting member to swing and further drives the supporting member to move.

[0019] Adopting the above technical solution, by arranging the driving roller to be rotatably connected to the end of the supporting member away from the base, when the driving member drives the driving roller to rotate relative to the supporting member, drives the intermediate connecting member to swing and further drives the supporting member to move, there is a larger moving space.

[0020] According to the base material roll pretreatment device of the bag forming machine provided by the present utility model, the supporting member includes a first support seat and a second support seat arranged at intervals in the width direction of the frame, and the intermediate connecting member includes a first swing arm and a second swing arm; and the limiting member is arranged as a limiting roller.

[0021] Furthermore, one end of the driving roller is rotatably connected to the first support seat, and the other end is rotatably connected to the second support seat. One end of the supporting member is rotatably connected to one end of the first swing arm, and the other end is rotatably connected to one end of the second swing arm. The other end of the first swing arm is drivingly connected to one end of the driving roller, and the other end of the second swing arm is drivingly connected to the other end of the driving roller; one end of the limiting roller is rotatably connected to the first swing arm, and the other end extends in the width direction of the frame and is rotatably connected to the second swing arm.

[0022] Adopting the above technical solution, by arranging one end of the supporting member to be rotatably connected to one end of the first swing arm and the other end to be rotatably connected to one end of the second swing arm; on the one hand, the base material roll located on the supporting member can be limited, so that the base material roll will not become loose due to the shaking of the base material roll pretreatment device of the bag forming machine; on the other hand, by arranging two swing arms to support the supporting member, when the base material roll is placed on the supporting member, sufficient supporting force is provided for the base material, improving the reliability of the base material roll pretreatment device of the bag forming machine.

[0023] According to the base material roll pretreatment device of the bag forming machine provided by the present utility model, one ends of the first swing arm and the second swing arm are both provided with bending parts adapted to the ends of the supporting parts. In the vertical direction, when the first swing arm and the second swing arm swing to the lowest position, the openings of the bending parts are flush with the central axis of the base material roll.

[0024] By adopting the above technical solution, when the staff assembles the base material roll onto the supporting part, the first swing arm and the second swing arm can be swung to the lowest position, and the openings of the bending parts are flush with the central axis of the base material roll, so that it is convenient for the staff to assemble the new base material roll onto the supporting part.

[0025] According to the base material roll pretreatment device of the bag forming machine provided by the present utility model, the lifting part includes a first driving cylinder and a second driving cylinder.

[0026] Further, along the conveying direction of the base material, the driving cylinder body of the first driving cylinder is fixedly connected to the middle position of the first swing arm, and the driving end of the first driving cylinder is connected to the base.

[0027] Further, along the conveying direction of the base material, the driving cylinder body of the second driving cylinder is fixedly connected to the middle position of the second swing arm, and the driving end of the second driving cylinder is connected to the base.

[0028] By adopting the above technical solution, since the driving cylinder body of the first driving cylinder is fixedly connected to the first swing arm and the driving cylinder body of the second driving cylinder is fixedly connected to the second swing arm, during the rotation process of the first swing arm and the second swing arm, the driving cylinder body of the driving cylinder will not limit the first swing arm and the second swing arm, so that the swing range of the first swing arm and the second swing arm is larger.

[0029] According to the base material roll pretreatment device of the bag forming machine provided by the present utility model, it further includes a plurality of feeding rollers arranged downstream of the base material roll; wherein, the plurality of feeding rollers are arranged at intervals between the first support seat and the second support seat along the conveying direction of the base material, and one ends of the plurality of feeding rollers are all rotatably connected to the first support seat, and the other ends all extend along the width direction of the machine frame and are rotatably connected to the second support seat.

[0030] By adopting the above technical solution, by arranging a plurality of feeding rollers, and since the first support seat and the second support seat are located on the downstream side of the supporting part along the conveying direction of the base material, therefore, when the base material roll located on the supporting part is driven by the first driving part to start conveying, the base material first passes through the plurality of feeding rollers; and since the plurality of feeding rollers are relatively close to the supporting part, the base material is supported and conveyed by the plurality of feeding rollers, reducing the probability of the base material running off track.

[0031] According to the base material roll pre-processing device of the bag forming machine provided by the utility model, the supporting component includes an inflatable shaft and a pair of locking components, and the first driving component includes a mounting bracket and a driving motor.

[0032] Furthermore, one end of the inflatable shaft is rotatably connected to one end of the first swing arm, and the other end is rotatably connected to one end of the second swing arm; a pair of locking members are installed at both ends of the inflatable shaft for locking the inflatable shaft, and a driving motor is installed at either end of the inflatable shaft for driving the inflatable shaft to rotate.

[0033] Furthermore, the mounting bracket is fixedly mounted on one end of the first swing arm or the second swing arm, the drive motor is fixedly mounted on the mounting bracket, and the drive end of the drive motor is transmission-connected to one end or the other end of the inflatable shaft, for driving the inflatable shaft to rotate relative to the first swing arm and the second swing arm.

[0034] With the above technical solution, when assembling the base material roll, the staff opens the locking member, removes the air shaft, sets the base material roll on the air shaft, and then places the air shaft on the first swing arm and the second swing arm, and installs the two ends of the air shaft on the first swing arm and the second swing arm through the locking member; when feeding, the air shaft is driven to rotate by the driving motor. Therefore, the setting of the locking member has the advantage of convenient material replacement.

[0035] According to the base material roll preprocessing device of the bag forming machine provided by the utility model, the support assembly also includes a position detection component, which is located on the downstream side of the adjustment mechanism in the conveying direction of the base material; the position detection component includes a correcting electric eye, a guide component and a power component, wherein the guide component is arranged on the frame in parallel with the support component, the power component is fixedly installed on the frame, the correcting electric eye is slidably arranged on the guide component, and the driving end of the power component is transmission-connected to the correcting electric eye.

[0036] Furthermore, the power component can drive the deflection-correcting electric eye to slide on the guide component, thereby changing the position of the deflection-correcting electric eye in the width direction of the frame to align with the initial positioning point of the base material roll.

[0037] By adopting the above technical solution, the deflection correction electric eye is set to be aligned with the initial positioning point of the base material roll. When the deflection correction electric eye deviates from the initial positioning point of the base material roll, the position of the base material roll can be adjusted by the position adjustment component to correct the position of the base material roll, thereby ensuring that the base material can be accurately pre-processed subsequently, such as folding, heat sealing and gluing.

[0038] When producing non-woven bags, different-sized non-woven bags need to be produced according to the bag type. Therefore, by setting a guiding member and a power member, the power member drives the deviation-correcting photoelectric eye to slide along the guiding member, thereby changing the position of the deviation-correcting photoelectric eye. When producing non-woven bags of different sizes, it can be aligned with the initial positioning point of the base material roll for producing non-woven bags of different bag types, having the advantage of high applicability.

[0039] According to the base material roll pretreatment device of the bag forming machine provided by the present utility model, the base material pretreatment mechanism includes a flat folding assembly, a heat sealing assembly, an adhesive pasting assembly, and a roller assembly that are sequentially arranged on the frame along the conveying direction of the base material.

[0040] Furthermore, the flat folding assembly is used to fold the two side edges of the base material during conveyance, the heat sealing assembly is used to perform heat sealing treatment on the two side folds of the base material during conveyance, the adhesive pasting assembly is used to paste glue on at least one side fold of the base material with a preset length, and the roller assembly is used to convey the base material after adhesive pasting treatment and adjust the conveying speed of the base material after adhesive pasting treatment.

[0041] By adopting the above technical solution, the base material can be pretreated by setting a flat folding assembly, a heat sealing assembly, an adhesive pasting assembly, and a roller assembly, thereby processing high-quality non-woven bags.

[0042] The beneficial effects of the present utility model are as follows:

[0081] The fabric pretreatment device is an indispensable equipment in the process of processing cloth bags. They play an important role in the early stage of fabric processing, aiming to improve the quality and processing efficiency of the fabric. The designs and functions of these devices vary, but the common goal is to provide a better foundation for subsequent fabric forming processes, such as hemming, indenting, and gluing. Therefore, it is essential for the fabric pretreatment device to perform deviation correction work during the production and manufacturing of cloth bags to ensure that the fabric maintains the correct position during processing and avoid deviation or offset.

[0082] The deviation correction mechanism on the fabric pretreatment device is a mechanical device specially designed to correct the side error of the fabric during forward movement. Its main function is to ensure the neatness of the fabric during production by adjusting the side position of the fabric, thereby improving production efficiency and product quality. In the prior art, most deviation correction mechanisms of fabric pretreatment devices mainly correct the fabric by adjusting the position of a certain component on the fabric conveying path; for example, a deviation correction roller is set to correct the fabric; or it directly acts on the fabric itself through pneumatic, electric, etc. methods to correct its position deviation.

[0083] However, in the production method of rectifying the fabric by adjusting the position of a certain component on the fabric conveying path, taking the setting of a rectifying roller as an example, during the production process, when the thickness of the fabric roll changes or the position of the fabric on the rectifying roller is corrected, there is an angular difference between the fabric on the rectifying roller and the fabric roll. During the process of conveying the fabric, the fabric is prone to deviation, and calibration is required again, with a high rectifying frequency, resulting in a high defective rate of the produced products.

[0084] Therefore, how to reduce the rectifying frequency of the fabric pretreatment device when processing the fabric so as to reduce the defective rate of the produced products has become an urgent problem to be solved.

[0085] To solve the above technical problems, the present utility model provides a base material roll pretreatment device for a bag forming machine, including a frame, a base material supply mechanism, and a base material pretreatment mechanism; the base material supply mechanism and the base material pretreatment mechanism are both arranged on the frame. The base material supply mechanism includes a support assembly and a position adjustment assembly; the support assembly includes a support component, an intermediate connection component, and a first driving component; the position adjustment assembly includes a base, a setting adjustment mechanism, and a second driving component; the adjustment mechanism can drive the intermediate connection component to rotate relative to the base, and further drive the support component to move; the second driving component drives the base to translate relative to the frame along the width direction of the frame, and further drives the adjustment mechanism and the support assembly to translate along the width direction of the frame; by adjusting the position of the base material roll in these two ways, the rectifying frequency during the conveying process of the base material is reduced, so that after the base material is conveyed to the pretreatment mechanism, the base material can be accurately pretreated, thereby reducing the defective rate of the produced products.

[0086] To make the purpose, technical solution, and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below in conjunction with the accompanying drawings.

[0087] First, a general description of the base material roll pretreatment device of the bag forming machine is given.

[0088] As Figure 1 and Figure 2 shown, the embodiment of the present utility model discloses a base material roll pretreatment device for a bag forming machine, including a frame 2, a base material supply mechanism, and a base material pretreatment mechanism 6. The base material supply mechanism and the base material pretreatment mechanism 6 are both arranged on the frame 2; moreover, the frame 2 is sequentially provided with a base material supply station 1 and a pretreatment station 5 along the conveying direction L of the base material. The base material pretreatment mechanism 6 is located at the base material supply station 1, and the base material pretreatment mechanism 6 is located at the pretreatment station 5; the base material pretreatment mechanism 6 can pretreat the edge of the base material, and the pretreatment includes at least one of hemming, heat sealing, and gluing.

[0089] The base material supply mechanism includes a support assembly 30 and a position adjustment assembly 31. The support assembly 30 is disposed at the upstream end of the frame 2 along the conveying direction L of the base material and supports the base material roll. It includes a support member 300 for supporting the base material roll, an intermediate connecting member 301 connecting the support member 300 to the position adjustment assembly 31, and a first driving member 302. And the position adjustment assembly 31 is disposed on the downstream side of the support member 300 in the conveying direction L of the base material. It includes a base 310 movably disposed on the base of the frame 2, an adjustment mechanism 311 disposed on the base 310, and a second driving member (not shown in the figure) disposed on the frame 2. The support member 300 is connected to the adjustment mechanism 311 through the intermediate connecting member 301 and extends outward from the front end of the frame 2.

[0090] The first driving member 302 is installed at one end of the intermediate connecting member 301 and is in transmission connection with the support member 300 for driving the support member 300 to rotate. The support member 300 is rotatably disposed at one end of the intermediate connecting member 301, and the other end of the intermediate connecting member 301 is connected to the adjustment mechanism 311. The adjustment mechanism 311 can drive the intermediate connecting member 301 to rotate relative to the base 310 and further drive the support member 300 to move. The second driving member drives the base 310 to translate relative to the frame 2 in the width direction W of the frame 2 and further drives the adjustment mechanism 311 and the support assembly 30 to translate in the width direction W of the frame 2.

[0091] Specifically, the working principle of the base material roll pretreatment device of this bag forming machine provided in this embodiment is as follows: When processing non-woven bags, the staff places the base material roll on the support member 300. By driving the intermediate connecting member 301 to rotate relative to the base 310 through the adjustment mechanism 311 and further driving the support member 300 to move, the position of the base material roll in the vertical direction can be adjusted. On the one hand, it makes the base material roll flush with the conveying plane of the base material in the height direction. On the other hand, the tension between the base material roll and the adjustment mechanism 311 can be adjusted, reducing the risk of breaking the base material during transportation due to excessive tension and reducing the wear degree of the base material during transportation. Then, the second driving member drives the base 310 to translate relative to the frame 2 in the width direction W of the frame 2 and further drives the adjustment mechanism 311 and the support assembly 30 to translate in the width direction W of the frame 2, so as to adjust the two ends of the base material roll located on the support member 300 to be aligned with the conveying plane of the base material in the width direction W of the frame 2.

[0092] Specifically, the position of the base material roll is adjusted by the above two methods, and then the support member 300 is driven to rotate by the first driving member 302. The base material roll is gradually unrolled, and the base material is conveyed in the conveying plane along the conveying direction L of the base material, so as to ensure that the base material can accurately enter the base material pretreatment mechanism 6 and the position will not shift. Therefore, after the base material is conveyed to the pretreatment mechanism, the base material can be accurately pretreated, such as hemming, heat sealing, pasting, etc.

[0093] More specifically, when the base material roll pretreatment device of the bag forming machine is conveying the base material, if the position of the base material shifts, such as when the base material runs off due to the shaking of the device or the thinning of the base material roll thickness, the position of the base material is adjusted by the above two adjustment methods, so that the base material roll and the conveyed base material are translated simultaneously along the width direction W of the frame 2, and the positions of the base material roll and the base material in the vertical direction are changed simultaneously, so that there is no angular difference between the base material roll and the conveyed base material. It has the advantages of low rectification frequency and high rectification accuracy, thus reducing the defective rate of the products produced.

[0094] Therefore, the base material roll pretreatment device of the bag forming machine provided by the present invention can adjust the tension between the base material roll and the adjusting mechanism 311, reducing the risk of breaking the base material during conveying due to excessive tension, and reducing the wear degree of the base material during conveying; reducing the rectification frequency of the base material during conveying, so that after the base material is conveyed to the pretreatment mechanism, the base material can be accurately pretreated, such as hemming, heat sealing, pasting, etc., thus reducing the defective rate of the products produced, and there is no angular difference between the base material roll and the conveyed base material, with the advantages of low rectification frequency and high rectification accuracy.

[0095] It should be understood that there is no angular difference between the base material roll and the conveyed base material, which means that there is no angular difference between the base material roll and the conveyed base material in both the horizontal direction and the vertical direction. That is, the two side edges of the base material roll in the horizontal direction are aligned with the two side edges of the conveyed base material in the horizontal direction, and the height of the base material roll in the vertical direction is the same as the height of the conveyed base material in the vertical direction.

[0096] Of course, it further needs to be understood that since the base material will gradually become thinner during the process of gradually unrolling the base material roll, the adjusting mechanism 311 can also be set to a normal operation state. When the base material is gradually unrolled, the adjusting mechanism 311 gradually drives the intermediate connecting member 301 to swing, so that the thinning size of the base material roll is synchronized with the swinging angle of the intermediate connecting member 301, thereby reducing the rectification frequency of the subsequent base material roll pretreatment device of the bag forming machine.

[0097] More specifically, the structure of the second driving component is not limited. For example, it can be a linear motor, an electric push rod, etc.

[0098] For example, in one embodiment, the second driving component is set as a linear motor. The linear motor is fixedly installed on the frame 2, and its driving end is in transmission connection with the base 310. When the linear motor is turned on, the base 310 is driven to translate along the width direction W of the frame 2 through its driving end.

[0099] In another embodiment, the second driving component is set as an electric push rod. The electric push rod is fixedly installed on the frame 2, and its driving end is in transmission connection with the base 310. When the electric push rod is turned on, the base 310 is driven to translate along the width direction W of the frame 2 through the driving end of the electric push rod.

[0100] The structure of the adjusting mechanism 311 of the intermediate connecting component 301 will be further described in detail below, so as to more clearly understand the rotation mode and running track of the intermediate connecting component 301.

[0101] As Figure 1 and Figure 2 shown, in the embodiment disclosed in this embodiment, the adjusting mechanism 311 includes a driving roller 3110, a driving member 3111 and a supporting member 3113. The supporting member 3113 is arranged on the base 310 extending in the vertical direction. The driving roller 3110 is rotatably connected to the end of the supporting member 3113 away from the base 310, so that the position of the driving roller 3110 in the vertical direction is far from the base 310. The other end of the intermediate connecting component 301 is in transmission connection with the end of the driving roller 3110. Furthermore, when the driving member 3111 drives the driving roller 3110 to rotate relative to the supporting member 3113, drives the intermediate connecting component 301 to swing and further drives the supporting member 300 to move, the intermediate connecting component 301 has a larger moving space.

[0102] Specifically, the driving member 3111 is installed on the supporting member 3113, and the driving end of the driving member 3111 is in transmission connection with the driving roller 3110. The driving member 3111 drives the driving roller 3110 to rotate relative to the supporting member 3113, drives the intermediate connecting component 301 to swing and further drives the supporting member 300 to move. Thus, the position of the supporting member 300 is changed in the vertical direction, and the position of the base material roll located on the supporting member 300 is adjusted, so that the position of the base material roll in the vertical direction can be flush with the conveying plane of the base material.

[0103] More specifically, the structure of the driving member 3111 is not limited. It can be set as an electric motor, a driving motor 3021, etc. The driving end of the driving motor 3021 or the electric motor is in transmission connection with the driving roller 3110 to drive the driving roller 3110 to rotate self.

[0104] More specifically, the transmission connection manner between the other end of the intermediate connection member 301 and the end of the driving roller 3110 is not limited.

[0105] For example, in one embodiment, a driving disk is provided at the end of the driving roller 3110. The driving disk is disposed around the end of the driving roller 3110 and fixedly connected to the driving roller 3110. The other end of the intermediate connection member 301 is fixedly connected to the driving disk. When the driving member 3111 drives the driving roller 3110 to rotate self - rotatably, it drives the driving disk to drive the intermediate connection member 301 to rotate relative to the support member 3113, thereby achieving the purpose of changing the position of the support member 300 in the vertical direction.

[0106] In another embodiment, a threaded hole is provided at the other end of the intermediate connection member 301, and a screw rod section is provided at the end of the driving roller 3110. The bolt connection is achieved by inserting the screw rod section into the mounting hole, so as to achieve the purpose of the transmission connection between the driving roller 3110 and the intermediate connection member 301.

[0107] In yet another embodiment, the other end of the intermediate connection member 301 and the end of the driving roller 3110 are welded to each other, thereby realizing the transmission connection between the intermediate connection member 301 and the driving roller 3110.

[0108] More specifically, the structures of the intermediate connection member 301 and the support member 3113 are not limited.

[0109] For example, in one embodiment disclosed in this embodiment, as Figure 1 and Figure 2 shown, the support member 3113 includes a first support seat 3113a and a second support seat 3113b that are spaced apart along the width direction W of the frame 2. The intermediate connection member 301 includes a first swing arm 3010 and a second swing arm 3011.

[0110] Specifically, one end of the driving roller 3110 is rotatably connected to the first support seat 3113a, and the other end is rotatably connected to the second support seat 3113b. One end of the support member 300 is rotatably connected to one end of the first swing arm 3010, and the other end is rotatably connected to one end of the second swing arm 3011. The other end of the first swing arm 3010 is in transmission connection with one end of the driving roller 3110, and the other end of the second swing arm 3011 is in transmission connection with the other end of the driving roller 3110.

[0111] More specifically, one end of the support member 300 is rotatably connected to one end of the first swing arm 3010, and the other end is rotatably connected to one end of the second swing arm 3011. On the one hand, the base material roll located on the support member 300 can be limited, so that the base material roll will not become loose due to the shaking of the base material roll pretreatment device of the bag forming machine. On the other hand, by providing two swing arms to support the support member 300, when the base material roll is placed on the support member 300, sufficient support force is provided for the base material, improving the reliability of the base material roll pretreatment device of the bag forming machine.

[0112] More specifically, one end of each of the first swing arm 3010 and the second swing arm 3011 is provided with a bent portion 3012 adapted to the end of the support member 300. In the vertical direction, when the first swing arm 3010 and the second swing arm 3011 swing to the lowest position, the opening of the bent portion 3012 is flush with the central axis of the base material roll. When the staff assembles the base material roll onto the support member 300, the first swing arm 3010 and the second swing arm 3011 are swung to the lowest position, and the opening of the bent portion 3012 is flush with the central axis of the base material roll, so as to facilitate the staff to assemble the new base material roll onto the support member 300.

[0113] More specifically, the shape of the bent portion 3012 is not limited. It can be an "L"-shaped bent portion 3012 with an opening facing the support member 300, or an inverted triangular bent portion 3012 with an opening facing the support member 300, etc. Those skilled in the art can set it according to their own needs, and this embodiment does not make a limitation here.

[0114] In another implementation manner disclosed in this embodiment, the support member 3113 includes a first triangular bracket and a second triangular bracket spaced along the width direction W of the frame 2, and the intermediate connecting member 301 includes a first rocker and a second rocker.

[0115] Specifically, one end of the driving roller 3110 is rotatably connected to the first triangular bracket, and the other end is rotatably connected to the second triangular bracket. One end of the support member 300 is rotatably connected to one end of the first rocker, and the other end is rotatably connected to one end of the second rocker. The other end of the first rocker is drivingly connected to one end of the driving roller 3110, and the other end of the second rocker is drivingly connected to the other end of the driving roller 3110. By setting the support member 3113 as a triangular bracket, when the driving member 3111 drives the driving roller 3110 to rotate relative to the support member 3113, drives the intermediate connecting member 301 to swing and further drives the support member 300 to move, the stability is higher.

[0116] The structure of the support member 300 will be further described in detail below to more clearly understand the connection relationship between the support member 300 and the intermediate connecting member 301.

[0117] like Figure 1 and Figure 2 As shown, in the embodiment disclosed in this embodiment, the support component 300 includes an inflatable shaft 3001 and a pair of locking members 3002, and the first driving component 302 includes a mounting bracket 3020 and a driving motor 3021. One end of the inflatable shaft 3001 is rotatably connected to one end of the first swing arm 3010, and the other end is rotatably connected to one end of the second swing arm 3011; a pair of locking members 3002 are installed at both ends of the inflatable shaft 3001 for locking the inflatable shaft 3001, and a driving member 3111 is installed at either end of the inflatable shaft 3001 for driving the inflatable shaft 3001 to rotate. The mounting bracket 3020 is fixedly mounted on one end of the first swing arm 3010 or the second swing arm 3011, the driving motor 3021 is fixedly mounted on the mounting bracket 3020, and the driving end of the driving motor 3021 is transmission-connected to one end or the other end of the inflatable shaft 3001, so as to drive the inflatable shaft 3001 to rotate relative to the first swing arm 3010 and the second swing arm 3011.

[0118] Specifically, when assembling the base material roll, the staff opens the locking member 3002, removes the air shaft 3001, sleeves the base material roll on the air shaft, and then places the air shaft on the first swing arm 3010 and the second swing arm 3011, and installs the two ends of the air shaft on the first swing arm 3010 and the second swing arm 3011 through the locking member 3002; when feeding, the air shaft is driven to rotate by the driving motor 3021, so that the base material roll on the air shaft 3001 is gradually opened. Therefore, the setting of the locking member 3002 has the advantage of convenient material replacement.

[0119] The structure of the locking member 3002 is not limited. For example, it can be configured as a pressure motor with a ring buckle at the driving end and a ring buckle.

[0120] For example, in one embodiment, the locking member 3002 is configured as a pressure motor with a ring buckle at the driving end. When installing the inflatable shaft 3001, the two ends of the inflatable shaft 3001 are respectively installed on the first swing arm 3010 and the second swing arm 3011 through the ring buckle at the driving end of the press. When removing the inflatable shaft 3001, the ring buckle is driven to open by the driving motor 3021 to remove the inflatable shaft 3001.

[0121] In another embodiment, the locking member 3002 is configured as an annular buckle, and a mounting hole is provided at the rotational connection between the first swing arm 3010 and the second swing arm 3011 and the end of the inflatable shaft 3001. When installing the inflatable shaft 3001, the staff inserts the annular buckle into the mounting hole to thereby install the inflatable shaft 3001 on the first swing arm 3010 and the second swing arm 3011. When removing the inflatable shaft 3001, the inflatable shaft 3001 is removed by opening the annular buckle.

[0122] It should be understood that when the locking member 3002 installs the inflatable shaft 3001 on the first swing arm 3010 and the second swing arm 3011, both ends of the inflatable shaft 3001 are rotationally connected to the first swing arm 3010 and the second swing arm 3011.

[0123] In the implementation method disclosed in this embodiment, Figure 1 and Figure 2 As shown, the support assembly 30 further includes a limiting component 303, and the structure and arrangement of the limiting component 303 are further described below.

[0124] In a feasible embodiment, the intermediate connecting component 301 extends obliquely upward from the rear end of the frame 2; the limiting component 303 is arranged at the other end of the intermediate connecting component 301 (the end connected to the limiting roller 3031 in transmission), and the limiting component 303 and the supporting component 300 are located on the same side of the intermediate connecting component 301, which is used to limit the base material roll.

[0125] Specifically, by setting the limiting component 303, on the one hand, the base material roll located on the supporting component 300 can be limited to prevent the base material roll from being loose; on the other hand, by measuring the distance between the supporting component 300 and the limiting component 303, the thickness of the base material roll can be determined to prevent the base material roll from abutting against the position adjustment component 31 due to being too thick, thereby affecting the transportation of the base material.

[0126] More specifically, the structure and form of the limiting component 303 are not limited, and it can be, for example, a limiting roller 3031, a limiting rod, a limiting rotating shaft, etc.

[0127] In a feasible implementation, the limiting component 303 is configured as a limiting roller 3031 , one end of which is rotatably connected to the first swing arm 3010 , and the other end of which extends along the width direction W of the frame 2 and is rotatably connected to the second swing arm 3011 .

[0128] In another feasible implementation, the limiting component 303 is configured as a limiting rod, one end of which is rotatably connected to the first swing arm 3010 , and the other end of which extends along the width direction W of the frame 2 and is rotatably connected to the second swing arm 3011 .

[0129] In the implementation method disclosed in this embodiment, Figure 1 and Figure 2 As shown, the position adjustment component 31 also includes a limiting component 303. The structure and setting method of the limiting component 303 are further described below.

[0130] In an implementable embodiment, the position adjustment assembly 31 further includes a lifting member 304 that can move in the vertical direction. One end of the lifting member 304 is installed on the base 310, and the other end is connected to the intermediate connection member 301, which is used to support the support assembly 30 and adjust the position of the support assembly 30 in the vertical direction.

[0131] Specifically, by providing the lifting member 304, on the one hand, the support assembly 30 can be supported, preventing the intermediate connection member 301 from rotating and falling back relative to the base 310 due to the excessive weight of the base material roll located on the support member 300, thus improving the reliability of the base material roll pretreatment device of the bag forming machine; on the other hand, by providing assistance for the intermediate connection member 301 to rotate relative to the base 310 through the lifting member 304, the reliability of the base material roll pretreatment device of the bag forming machine during use is also higher.

[0132] More specifically, the structure and form of the lifting member 304 are not limited. For example Figure 1 and Figure 2 As shown, in an implementable embodiment, the lifting member 304 includes a first driving cylinder 3040 and a second driving cylinder 3041; along the conveying direction L of the base material, the driving cylinder body of the first driving cylinder 3040 is fixedly connected to the middle position of the first swing arm 3010, and the driving end of the first driving cylinder 3040 is connected to the base 310; the driving cylinder body of the second driving cylinder 3041 is fixedly connected to the middle position of the second swing arm 3011, and the driving end of the second driving cylinder 3041 is connected to the base 310.

[0133] More specifically, since the driving cylinder body of the first driving cylinder 3040 is fixedly connected to the first swing arm 3010 and the driving cylinder body of the second driving cylinder 3041 is fixedly connected to the second swing arm 3011, during the rotation of the first swing arm 3010 and the second swing arm 3011, the driving cylinder body of the driving cylinder will not limit the first swing arm 3010 and the second swing arm 3011, so that the swing range of the first swing arm 3010 and the second swing arm 3011 is larger.

[0134] More specifically, since the driving cylinder body of the first driving cylinder 3040 is fixedly connected to the middle position of the first swing arm 3010 and the driving cylinder body of the second driving cylinder 3041 is fixedly connected to the middle position of the second swing arm 3011. Therefore, through this setting method, the stress of the base material roll located on the support member 300 can be reasonably distributed, reducing the risk that the transmission connection between the first swing arm 3010 and the second swing arm 3011 and the driving roller 3110 is disconnected due to excessive bearing capacity caused by the excessive weight of the base material roll.

[0135] It should be understood that the driving ends of the first driving cylinder 3040 and the second driving cylinder 3041 are both rotatably connected to the base 310, so that when the first swing arm 3010 and the second swing arm 3011 swing, the first driving cylinder 3040 and the second driving cylinder 3041 can also swing accordingly to adapt to the swing angles of the first swing arm 3010 and the second swing arm 3011.

[0136] In another implementable embodiment, the lifting member 304 includes a first electric push rod and a second electric push rod; along the conveying direction L of the base material, the power motor of the first electric push rod is fixedly connected to the middle position of the first swing arm 3010, and the driving end of the first electric push rod is connected to the base 310; the power motor of the second electric push rod is fixedly connected to the middle position of the second swing arm 3011, and the driving end of the second electric push rod is connected to the base 310.

[0137] In the embodiment disclosed in the present embodiment, as Figure 1 and Figure 2 shown, the base material roll pretreatment device of the bag forming machine further includes a plurality of feeding rollers 4 arranged downstream of the base material roll. The structure and arrangement mode of the plurality of feeding rollers 4 will be further described below.

[0138] In one implementable embodiment, the plurality of feeding rollers 4 are arranged at intervals between the first support seat 3113a and the second support seat 3113b along the conveying direction L of the base material, and one ends of the plurality of feeding rollers 4 are all rotatably connected to the first support seat 3113a, and the other ends all extend along the width direction W of the frame 2 and are rotatably connected to the second support seat 3113b.

[0139] Specifically, by arranging a plurality of feeding rollers 4, and since the first support seat 3113a and the second support seat 3113b are located on the downstream side of the support member 300 along the conveying direction L of the base material, when the base material roll on the support member 300 is driven by the first driving member 302 to start conveying, the base material first passes through the plurality of feeding rollers 4; and since the plurality of feeding rollers 4 are relatively close to the support member 300, the base material is supported and conveyed by the plurality of feeding rollers 4, reducing the probability of the base material running off track.

[0140] More specifically, the number of the plurality of feeding rollers 4 can be set to 2, 3, 5, etc. Those skilled in the art can set it according to their own needs, and this embodiment does not make a limitation here.

[0141] In the embodiment disclosed in the present embodiment, as Figures 1 - 3 shown, the support assembly 30 further includes a position detection member 305. The structure and setting mode of the position detection member 305 will be further described below.

[0142] In an achievable implementation, the position detection component 305 is located on the downstream side of the adjustment mechanism 311 in the conveying direction L of the base material; the position detection component 305 includes a deviation correction photoelectric eye 3050, a guiding member 3051, and a power member 3052. Among them, the guiding member 3051 is arranged on the frame 2 in parallel with the supporting component 300, the power member 3052 is fixedly installed on the frame 2, the deviation correction photoelectric eye 3050 is slidably arranged on the guiding member 3051, and the driving end of the power member 3052 is in transmission connection with the deviation correction photoelectric eye 3050. The power member 3052 can drive the deviation correction photoelectric eye 3050 to slide on the guiding member 3051, changing the position of the deviation correction photoelectric eye 3050 in the width direction W of the frame 2 to align with the initial positioning point of the base material roll.

[0143] Specifically, by setting the deviation correction photoelectric eye 3050 to align with the initial positioning point of the base material roll, when the deviation correction photoelectric eye 3050 deviates from the initial positioning point of the base material roll, the position of the base material roll can be adjusted through the position adjustment assembly to correct the position of the base material roll, thereby ensuring accurate pre-treatment of the base material in the subsequent process, such as hemming, heat sealing, and pasting.

[0144] The structure of the guiding member 3051 is not limited. For example, it can be a guide rod, a guide rail, or a slide rail, etc.

[0145] The structure of the power member 3052 is not limited. For example, it can be a combination of a handwheel, a slider, and a lead screw, or an electric push rod and a linear motor, etc.

[0146] In an achievable implementation, the guiding member 3051 is set as a guide rod, the power member 3052 includes a handwheel and a lead screw, the deviation correction photoelectric eye 3050 is slidably connected to the guide rod, the slider is screwed onto the lead screw, and the slider is fixedly connected to the deviation correction photoelectric eye 3050. When it is necessary to change the position of the deviation correction photoelectric eye 3050, the staff can drive the deviation correction photoelectric eye 3050 to slide along the guide rod by turning the handwheel, changing the position of the deviation correction photoelectric eye 3050, and it has the advantage of convenient operation.

[0147] In an achievable implementation, the guiding member 3051 is set as a guide rail, the power member 3052 is set as an electric push rod, the deviation correction photoelectric eye 3050 is slidably connected to the guide rail, and the driving end of the electric push rod is in transmission connection with the deviation correction photoelectric eye 3050. When it is necessary to change the position of the deviation correction photoelectric eye 3050, the staff can open the electric push rod to push the deviation correction photoelectric eye 3050 to slide along the guide rail, changing the position of the deviation correction photoelectric eye 3050.

[0148] It should be understood that the initial positioning point of the base material roll is a target located on the base material roll. When the deviation correction photoelectric eye 3050 is aligned with the initial positioning point, the height of the base material roll in the vertical direction is flush with the height of the conveying plane of the base material in the vertical direction. In the width direction W of the frame 2, the two side edges of the base material roll are aligned with the two side edges of the conveying plane of the base material.

[0149] More specifically, the position detection component 305 further includes a controller, which is installed on the frame 2 and electrically connected to the deviation correction photoelectric eye 3050, the driving member 3111 of the adjustment mechanism 311, and the second driving component. Among them, the deviation correction photoelectric eye 3050 is used to collect the position information of the fabric during the conveying process and feedback the position information to the controller. When the position information of the fabric collected by the deviation correction photoelectric eye 3050 is offset, the controller controls the second driving component to drive the base 310 to move and adjust the position of the base material in the width direction W of the frame 2. The controller controls the driving member 3111 of the adjustment mechanism 311 to adjust the position of the base material in the vertical direction, so that the deviation correction photoelectric eye 3050 is always aligned with the initial positioning point of the base material roll, improving the quality of the produced products.

[0150] In the implementation manner disclosed in this embodiment, as Figures 4 - 7 shown, the structure and setting method of the base material pretreatment mechanism 6 located at the pretreatment station 5 on the frame 2 will be further described below.

[0151] In a realizable implementation manner, the base material pretreatment mechanism 6 includes a flat folding assembly 60, a heat sealing assembly 61, an adhesive pasting assembly 62, and a roller assembly 63 that are sequentially arranged on the frame 2 along the conveying direction L of the base material. The flat folding assembly 60 is used to fold the two side edges of the conveying base material, the heat sealing assembly 61 is used to perform heat sealing treatment on the two side folds of the conveying base material, the adhesive pasting assembly 62 is used to paste glue on at least one side fold of the base material with a preset length, and the roller assembly 63 is used to convey the base material after the adhesive pasting treatment and adjust the conveying speed of the base material after the adhesive pasting treatment.

[0152] Specifically, by setting the flat folding assembly 60, the heat sealing assembly 61, the adhesive pasting assembly 62, and the roller assembly 63, the base material can be pretreated, so that the quality of the processed non-woven fabric bag is relatively high.

[0153] In the implementation manner disclosed in this embodiment, as Figure 4 and Figure 5 shown, the structure and setting method of the flat folding assembly 60 will be further explained below.
