Description

Technical Field

[0001] This utility model relates to the field of sealed bag transmission technology, and more specifically, it relates to a sealed bag transmission device with a swing tensioning function. Background Technology

[0002] In order to meet the requirements of continuous output and continuous processing during factory processing, sealing bags are usually transported over long distances and processed continuously without interruption on the production line. For example, multiple processing steps may be carried out on the same processing line to shorten the forming time, reduce processing and transportation costs, and achieve efficient production with less human intervention.

[0003] Currently, during the feeding stage of sealed bag processing, the sealed bag rolls are usually very large and heavy. There are usually two situations: motor-assisted release or free release. Both of these production conditions can lead to excessive release. The loosening of the sealed bag caused by excessive release will directly cause wrinkles during the transmission of the sealed bag. The appearance of wrinkles during the uninterrupted transmission process will cause complete chaos in subsequent processing. Utility Model Content

[0004] The purpose of this invention is to provide a sealing bag transmission device with a swing tensioning function, and a sealing bag tensioning device that can tighten excessively released sealing bags.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a sealing bag transmission device with swing tensioning function, including a mounting frame, a feeding assembly, a tensioning assembly and a transmission assembly.

[0006] The mounting frame is a frame structure formed by combining several profiles;

[0007] A feeding assembly is provided at one end of the mounting frame to feed materials toward the far end of the mounting frame;

[0008] The tensioning assembly is disposed on the mounting frame and located in the feeding direction of the feeding assembly. The tensioning assembly includes a mounting base fixedly disposed at the bottom of the mounting frame, a rotating roller disposed on the mounting base, a suspension frame disposed on the side of the mounting base away from the feeding assembly, at least one suspension roller disposed on the suspension frame, and the tensioning assembly also includes a fixing frame disposed on the top surface of the mounting frame, and at least two fixing rollers disposed side by side between the fixing frames.

[0009] A transmission component is mounted on the mounting frame and located on the side of the tensioning component away from the feeding component;

[0010] The sealed bag is wound and overlapped by the fixed roller close to the feeding component from the feeding component, and then wound and abutted by the hanging roller, so that the hanging roller tensions the sealed bag. The sealed bag is then overlapped by the fixed roller away from the feeding component and connected to the transmission component.

[0011] By setting a tensioning component between the transmission component and the feeding component, the speed difference between the transmission component and the feeding component can be effectively reduced.

[0012] The fixed roller effectively prevents the sealed bag from contacting the frame and causing damage.

[0013] The fixed roller setting can also effectively change the transmission direction of the sealed bag, so that it fits more closely to the transmission roller. After fitting closely to the transmission roller, the downward tension will prevent wrinkles from appearing. Even if wrinkles appear, the tension will open up the wrinkles of the sealed bag.

[0014] The present invention is further configured such that: two horizontally arranged and spaced-apart suspension rollers are provided on the suspension frame, and three fixed rollers arranged and spaced-apart along the axial direction of the fixed frame are provided on the fixed frame, and the suspension rollers are respectively arranged between the gaps of the fixed rollers.

[0015] The suspension rollers effectively tighten the sealing bag.

[0016] The present invention is further configured such that the rotating roller is a damping roller capable of rotating slowly.

[0017] By setting the rotating roller as a damping roller, bag jumping can be prevented.

[0018] The present invention is further configured such that the fixed roller and the suspension roller are optical shaft rollers.

[0019] The optical axis setting helps guide the bag while preventing scratches from forming on the sealed bag.

[0020] The present invention is further configured such that: the feeding assembly includes a mounting plate disposed at the end of the mounting frame; a release motor is disposed on the side of the mounting plate away from the conveying direction of the mounting frame; a detachable release roller is disposed on the output end of the release motor; a quick-release base is disposed on the side of the mounting frame away from the mounting plate corresponding to the release motor; one end of the release roller is poweredly connected to the release motor; and the other end is rotatably disposed on the quick-release base.

[0021] The release roller allows the release speed of the roll material to be controlled by the release motor, preventing excessive release speed differences caused by inertial release due to pulling.

[0022] The present invention is further configured such that: the transmission assembly includes platform plates disposed on both sides of the top surface of the mounting frame, two longitudinally parallel transmission rollers are disposed between the two platform plates, the two transmission rollers abut against each other, and the two transmission rollers squeeze and transmit the sealed bag, at least one end of the transmission roller closer to the top surface of the mounting frame passes through one of the platform plates, and the portion of the transmission roller passing through the platform plate is provided with a driven wheel, the transmission assembly also includes a lower platform plate on the same side as the driven wheel and located on the bottom surface of the mounting frame, a driving wheel is also disposed on the same side of the lower platform plate as the driven wheel, and a transmission motor is also disposed on the side of the lower platform plate away from the driving wheel, and the output end of the transmission motor passes through the lower platform plate and is poweredly connected to the driving wheel.

[0023] The arrangement of the transfer rollers allows the folds to unfold according to the tension during transmission. The transfer roller closer to the bottom acts as a power roller, which can better apply power to the transmission and also counteract the sag effect of the suspension frame, preventing transmission failure due to excessive sag force.

[0024] In summary, this utility model has the following beneficial effects:

[0025] By setting a tensioning component between the transmission component and the feeding component, the speed difference between the transmission component and the feeding component can be effectively reduced.

[0026] The fixed roller effectively prevents the sealed bag from coming into contact with the mounting frame and causing damage.

[0027] The fixed roller setting can also effectively change the transmission direction of the sealed bag, so that it fits more closely to the transmission roller. After fitting closely to the transmission roller, the downward tension will prevent wrinkles from appearing. Even if wrinkles appear, the tension will open up the wrinkles of the sealed bag.

[0040] Example

[0041] like Figure 1 , Figure 2As shown, a sealing bag transmission device with swing tensioning function includes a mounting frame, a feeding assembly 2, a tensioning assembly 3, and a transmission assembly 4.

[0042] The mounting frame is a frame structure formed by combining several profiles.

[0043] The feeding component 2 is located at one end of the mounting frame and feeds materials towards the far end of the mounting frame.

[0044] The tensioning assembly 3 is mounted on the mounting frame and located in the feeding direction of the feeding assembly 2. The tensioning assembly 3 includes a mounting base 32 fixedly mounted at the bottom of the mounting frame. A rotating roller 31 is mounted on the mounting base 32. A suspension frame 33 is mounted on the side of the mounting base away from the feeding assembly 2. At least one suspension roller 34 is mounted on the suspension frame 33. The tensioning assembly 3 also includes a fixing frame 36 mounted on the top surface of the mounting frame. At least two fixing rollers 37 are arranged side by side between the fixing frames 36.

[0045] The transmission component 4 is placed on the mounting frame and located on the side of the tensioning component 3 away from the feeding component 2.

[0046] The sealed bag is wound and overlapped with the fixed roller 37 close to the feeding component 2, and then wound and abutted against the suspension roller 34, so that the suspension roller 34 tensions the sealed bag. The sealed bag is then overlapped with the fixed roller 37 away from the feeding component 2 and connected to the transmission component 4.

[0047] By setting a tensioning component 3 between the transmission component 4 and the feeding component 2, the transmission speed difference between the transmission component 4 and the feeding component 2 can be effectively reduced.

[0048] The fixed roller 37 effectively prevents the sealed bag from coming into contact with the mounting frame and causing damage.

[0049] The setting of the fixed roller 37 can also effectively change the transmission direction of the sealed bag, so that it is closer to the transmission roller 42. After being close to the transmission roller 42, it can prevent wrinkles from appearing due to its downward tension. Even if wrinkles appear, the tension will open the wrinkles of the sealed bag.

[0050] The suspension frame 33 is provided with two horizontally parallel and spaced-apart suspension rollers 34, and the fixed frame 36 is provided with three fixed rollers 37 arranged in parallel and spaced-apart along the axial direction of the fixed frame 36. The suspension rollers 34 are all correspondingly arranged between the gaps of the fixed rollers 37. The suspension rollers 34 can effectively tighten the sealing bag.

[0051] The rotating roller 31 is a damping roller that can rotate slowly; by setting the rotating roller 31 as a damping roller, the occurrence of bag jumping can be prevented.

[0052] The fixed roller 37 and the hanging roller 34 are optical axis rollers; the optical axis setting can prevent scratches on the sealed bag body while guiding.

[0053] like Figure 2 As shown, a load-bearing plate 35 is provided on the end of the suspension frame 33 away from the rotating roller 31, and a load can be added to the load-bearing plate 35.

[0054] The feeding assembly 2 includes a mounting plate 24 disposed at the end of the mounting frame. A release motor 23 is disposed on the side of the mounting plate 24 away from the conveying direction of the mounting frame. A detachable release roller is disposed on the output end of the release motor 23. A quick-release base 21 is disposed on the side of the mounting frame away from the mounting plate 24 corresponding to the release motor 23. One end of the release roller is poweredly connected to the release motor 23, and the other end is rotatably disposed on the quick-release base 21. The release roller 22 can control the release speed of the roll material through the release motor 23 to prevent inertial release due to pulling, which would result in an excessively large difference in release speed.

[0055] The transmission assembly 4 includes two platform plates 41 disposed on both sides of the top surface of the mounting frame. Two longitudinally arranged transmission rollers 42 are disposed between the two platform plates 41. The two transmission rollers 42 abut against each other and compress the sealed bag for transmission. At least one end of the transmission roller 42 closer to the top surface of the mounting frame passes through one of the platform plates 41. A driven wheel is disposed on the part of the transmission roller 42 that passes through the platform plate 41. The transmission assembly 4 also includes a lower platform plate 45 on the same side as the driven wheel and located on the bottom surface of the mounting frame. A drive wheel is disposed on the same side of the lower platform plate 45 as the driven wheel. A transmission motor 46 is disposed on the side of the lower platform plate 45 away from the drive wheel, and the output end of the transmission motor 46 passes through the lower platform plate 45 and is poweredly connected to the drive wheel. The arrangement of the transmission rollers 42 allows the folds to unfold according to the tension during transmission. The transmission roller 42 closer to the bottom acts as a drive roller, which can better apply power to the transmission and also counteract the hanging effect of the suspension frame 33, preventing transmission failure due to excessive hanging force.

[0056] In summary, this utility model has the following beneficial effects:

[0057] By setting a tensioning component 3 between the transmission component 4 and the feeding component 2, the transmission speed difference between the transmission component 4 and the feeding component 2 can be effectively reduced.

[0058] The fixed roller 37 effectively prevents the sealed bag from contacting the mounting frame and causing damage.

[0059] The setting of the fixed roller 37 can also effectively change the transmission direction of the sealed bag, so that it is closer to the transmission roller 42. After being close to the transmission roller 42, it can prevent wrinkles from appearing due to its downward tension. Even if wrinkles appear, the tension will open the wrinkles of the sealed bag.

[0060] It should be noted that all features disclosed in this specification, or all steps in all methods or processes disclosed, may be combined in any way, except for mutually exclusive features and / or steps.

[0061] Furthermore, the specific embodiments described above are exemplary.
