Description

Technical Field

[0001] This utility model belongs to the field of packaging bag processing technology, and specifically relates to a packaging bag anti-leakage processing device. Background Technology

[0002] Food packaging bags are a type of packaging design. In order to facilitate the preservation and storage of food, food packaging bags have been developed. Food packaging bags refer to thin film containers that come into direct contact with food and are used to hold and protect food. When sealing food packaging bags, food packaging bag processing equipment is required to seal them.

[0003] In the prior art, CN202120629291.6 discloses an air-leakage prevention processing device for food packaging bags, including: a mounting plate, a collection box, and a worktable. A first sealing wheel is movably mounted on the surface of the mounting plate on one side of the transmission wheel, and a second sealing wheel is movably mounted on the surface of the mounting plate on one side of the first sealing wheel. A storage box is movably mounted between the sliding frames. A collection box is movably mounted on one side of the worktable at the bottom of the storage box. A display is fixedly mounted on the surface of the collection box. An infrared counter is fixedly mounted on one side inside the collection box. A weighing sensor is movably mounted on the bottom of the collection box.

[0004] In practical use, the above-mentioned technology lacks a clamping and conveying mechanism for the packaging bags. The device only uses a pair of guide wheels to convey the packaging bags forward. When the packaging bags move between the guide wheels and the sealing wheels, if the packaging bag is not long enough, it is easy for the packaging bags to fall off. After falling off, the operator needs to bring the packaging bags back to the front end and reload them onto the equipment for sealing, thus resulting in low processing efficiency.

[0005] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a packaging bag anti-leakage processing device.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] The purpose of this utility model is to provide a packaging bag anti-leakage processing device, which can solve the problem that packaging bags are easy to fall off when using existing packaging bag processing devices.

[0008] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0009] A packaging bag anti-leakage processing device includes: a base plate, a conveying trough, a pair of drive shafts, a pair of driven shafts, a pair of chains, a transmission assembly, a sealing mechanism, and a cutting mechanism.

[0010] A support plate is fixed to the top of the base plate. The conveying trough is horizontally carved into the support plate. A pair of drive shafts and a pair of driven shafts are respectively installed at both ends of the support plate and symmetrically arranged on both sides of the conveying trough. A drive wheel and a driven wheel are respectively installed at one end of the drive shafts and the driven shafts on the back side of the support plate. A pair of chains are respectively installed on the drive wheel and the driven wheel, and multiple clamps are tightly installed on each chain. The transmission assembly is installed on the base plate and is used to simultaneously drive the pair of drive shafts to rotate in opposite directions.

[0011] The sealing mechanism is mounted on a support plate and includes two pairs of drive shafts, two pairs of chain teeth, and two pairs of sealing wheels. The two pairs of drive shafts rotate on the support plate and are symmetrically arranged on both sides of the conveying trough. The two pairs of chain teeth are respectively mounted on the ends of the two pairs of drive shafts near the chains, and each pair of chain teeth meshes with a pair of chains. The two pairs of sealing wheels are respectively mounted on the ends of the two pairs of drive shafts away from the chain teeth.

[0012] The cutting mechanism is installed at the end of the conveyor trough furthest from the drive wheel, and is used to trim the excess portion of the sealed packaging bag. The receiving mechanism is installed at the end of the support plate furthest from the drive wheel, and is used to collect the sealed packaging bags and the trimmed scraps.

[0013] In one embodiment of this utility model, a guide plate is provided at one end of the conveying trough near the drive wheel, so that the packaging bag can be easily slid into the conveying trough and between a pair of chains.

[0014] In one embodiment of this utility model, a pair of right-angled plates are fixed to the bottom of each of the plurality of clamping blocks, and the pair of right-angled plates are respectively fixed to the two side walls of the chain. The clamping blocks are fixed to the two side walls of the chain by the pair of right-angled plates, thereby being installed on the clamping blocks.

[0015] In one embodiment of this utility model, support rails are installed on the back of the support plate at the inner wall of the two chains that are close to each other. The chains slide within the support rails. The support rails support the two chains, thereby preventing the two chains from clamping the packaging bag in the middle and preventing the two chains from deforming inward, which would cause the clamping of the packaging bag to loosen.

[0016] In one embodiment of this invention, a support slide plate is installed on the front side of the support plate at the bottom of the conveying trough. When the packaging bag slides along the conveying trough, the support slide plate supports the packaging bag, allowing the packaging bag to slide more smoothly between a pair of sealing wheels.

[0017] In one embodiment of this utility model, the transmission assembly includes: a bearing seat and a pair of spur gears. The bearing seat is fixed to a base plate and located on one side of a pair of drive wheels. The ends of the pair of drive shafts near the drive wheels rotate on the bearing seat. The pair of spur gears are respectively mounted on the pair of drive shafts, and the pair of spur gears mesh with each other. In use, one end of one drive shaft needs to be externally driven by a drive motor. The drive shaft synchronously drives the other drive shaft to rotate in the opposite direction through the pair of spur gears. This causes the pair of drive shafts to drive a pair of chains to rotate synchronously in the opposite direction through the pair of drive wheels. Thus, the pair of chains clamp the packaging bag forward through multiple clamps on them for transport.

[0018] In one embodiment of this utility model, a pair of clamping plates are fixed to the side of the support plate near the chain. The pair of clamping plates are respectively disposed at the upper and lower ends of the pair of chains and at the two pairs of chain teeth. The pair of clamping plates are used to limit the position of the chain, so that the two pairs of chain teeth can always mesh with the pair of chains.

[0019] In one embodiment of this invention, multiple pulleys are mounted on each of the pair of clamps. The pulleys are used to reduce the friction between the clamps and the chain.

[0020] In one embodiment of this utility model, the cutting mechanism includes: a T-shaped mounting groove, a T-shaped component, and a pair of conveyor wheels. The T-shaped mounting groove is carved into the side wall of the support plate near the chain and is located at the end of the conveyor groove away from the drive wheel. The T-shaped component is installed in the T-shaped mounting groove, and a V-shaped cutting head is provided at its end near the drive wheel. The pair of conveyor wheels are respectively fixed to a pair of driven shafts located at the front end of the support plate. After the packaging bag is sealed by the two pairs of sealing wheels and moves to the pair of conveyor wheels, it is clamped onto the packaging bag by the pair of conveyor wheels and the pair of chains, and the packaging bag passes through the V-shaped cutting head, so that the V-shaped cutting head cuts the packaging bag, cutting off the excess part at the end of the packaging bag. The T-shaped mounting groove is used for the embedded installation of the T-shaped component.

[0021] In one embodiment of this utility model, the receiving mechanism includes a material box and a waste box. The material box is fixed to the front side of the support plate away from the drive wheel, and a second sliding plate is fixed thereon. The waste box is fixed to the rear side of the support plate away from the drive wheel, and a first sliding plate is fixed thereon. The material box is used to store sealed packaging bags, and the waste box is used to store cut plastic scraps. After the packaging bag slides along the conveyor trough to the end of the conveyor trough away from the drive wheel, the cut packaging bag slides down the second sliding plate into the material box, and the corner scraps slide down the first sliding plate into the waste box.

[0022] Compared with the prior art, the packaging bag anti-leakage processing device of this utility model uses a pair of chains to clamp the packaging bag and drive the packaging bag forward for conveying, sealing and cutting, which reduces the problem of packaging bags falling and effectively improves processing efficiency.

Detailed Implementation

[0031] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0032] like Figures 1 to 5 As shown, an embodiment of the present invention provides a packaging bag anti-leakage processing device, comprising: a base plate 1, a conveying groove 102, a pair of drive shafts 104, a pair of driven shafts 106, a pair of chains 108, a transmission assembly, a sealing mechanism 2, and a cutting mechanism 3.

[0033] like Figures 1 to 5 As shown, a support plate 101 is fixed to the top of the base plate 1. A conveying groove 102 is horizontally carved into the support plate 101. A pair of drive shafts 104 and a pair of driven shafts 106 are respectively installed at both ends of the support plate 101 and symmetrically arranged on both sides of the conveying groove 102. A drive wheel 105 and a driven wheel 107 are respectively installed at one end of the pair of drive shafts 104 and the pair of driven shafts 106 on the back side of the support plate 101. A pair of chains 108 are respectively installed on the pair of drive wheels 105 and driven wheels 107, and multiple clamping blocks 110 are tightly installed on each pair of chains 108. A transmission assembly is installed on the base plate 1 and is used to simultaneously drive the pair of drive shafts 104 to rotate in opposite directions.

[0034] In use, the transmission assembly simultaneously drives a pair of drive shafts 104 to rotate in opposite directions. The drive shafts 104 drive a pair of drive wheels 105 to rotate synchronously. The drive wheels 105 drive a pair of chains 108 to rotate simultaneously in opposite directions. When the chains 108 rotate, the driven shaft 106 and driven wheel 107 assist the chains 108 in rotating. When the other pair of chains 108 rotates, the packaging bag slides from one end of the pair of conveying grooves 102 near the drive wheels 105 into the conveying grooves 102. The end of the packaging bag is clamped by the clamps 110 on the chains 108, causing the chains 108 to slide the packaging bag from one end of the conveying groove 102 to the other.

[0035] like Figures 1 to 5As shown, the sealing mechanism 2 is mounted on the support plate 101. The sealing mechanism 2 includes two pairs of drive shafts 201, two pairs of chain teeth 202, and two pairs of sealing wheels 203. Both pairs of drive shafts 201 rotate on the support plate 101 and are symmetrically arranged on both sides of the conveying trough 102. The two pairs of chain teeth 202 are respectively mounted on the ends of the two pairs of drive shafts 201 near the chain 108, and each pair of chain teeth 202 meshes with a pair of chains 108. The two pairs of sealing wheels 203 are respectively mounted on the ends of the two pairs of drive shafts 201 away from the chain teeth 202.

[0036] In use, when a pair of chains 108 rotate, they drive two pairs of chain teeth 202 to rotate. The two pairs of chain teeth 202 drive two pairs of sealing wheels 203 to rotate through two pairs of transmission shafts 201. When a pair of chains 108 moves the packaging bag to the two pairs of sealing wheels 203, the packaging bag is double-sealed by the two pairs of sealing wheels 203.

[0037] like Figures 1 to 5 As shown, the cutting mechanism 3 is installed at the end of the conveying trough 102 away from the drive wheel 105, and is used to trim the excess part of the sealed packaging bag end. The receiving mechanism 4 is installed at the end of the support plate 101 away from the drive wheel 105, and is used to collect the sealed packaging bag and the cut scraps.

[0038] like Figures 1 to 5 As shown, a guide plate 103 is provided at one end of the conveying trough 102 near the drive wheel 105, which facilitates the sliding of the packaging bag into the conveying trough 102 and between the pair of chains 108. A pair of right-angle plates 109 are fixed to the bottom of each of the multiple clamping blocks 110, and the pair of right-angle plates 109 are respectively fixed to the two side walls of the chains 108. The clamping blocks 110 are fixed to the two side walls of the chains 108 by the pair of right-angle plates 109, thus being mounted on the clamping blocks 110.

[0039] like Figures 1 to 5 As shown, support rails 113 are installed on the back of the support plate 101 at the inner walls of the ends of the pairs of chains 108 that are close to each other. The chains 108 slide within the support rails 113. The support rails 113 support the pairs of chains 108, thereby preventing the chains 108 from clamping the packaging bag in the middle and preventing the chains 108 from deforming inward, which would cause the clamping of the packaging bag to loosen. A support slide plate 114 is installed on the front side of the support plate 101 at the bottom of the conveyor trough 102. When the packaging bag slides along the conveyor trough 102, the support slide plate 114 supports the packaging bag, allowing the packaging bag to slide more smoothly between the pairs of sealing wheels 203.

[0040] like Figures 1 to 5As shown, the transmission assembly includes a bearing seat 111 and a pair of spur gears 112. The bearing seat 111 is fixed to the base plate 1 and located on one side of a pair of drive wheels 105. The ends of a pair of drive shafts 104 near the drive wheels 105 rotate on the bearing seat 111. The pair of spur gears 112 are respectively mounted on the pair of drive shafts 104, and the pair of spur gears 112 mesh with each other. In use, one end of one of the drive shafts 104 requires an external drive motor, model KF107DRN132M4. The drive shaft 104 synchronously drives the other drive shaft 104 to rotate synchronously in the opposite direction through the pair of spur gears 112. This causes the pair of drive shafts 104 to drive a pair of chains 108 to rotate synchronously in the opposite direction through the pair of drive wheels 105. This causes the pair of chains 108 to clamp the packaging bag forward through multiple clamps 110 on them.

[0041] like Figures 1 to 5 As shown, a pair of clamping plates 204 are fixed to the support plate 101 near the chain 108. The pair of clamping plates 204 are respectively located at the upper and lower ends of the pair of chains 108 and at the two pairs of chain teeth 202. The pair of clamping plates 204 are used to limit the position of the chain 108, so that the two pairs of chain teeth 202 can always mesh with the pair of chains 108. Multiple pulleys 205 are installed on each pair of clamping plates 204. The pulleys 205 are used to reduce the friction between the clamping plates 204 and the chain 108.

[0042] like Figures 1 to 5 As shown, the cutting mechanism 3 includes a T-shaped mounting groove 301, a T-shaped component 302, and a pair of conveyor wheels 304. The T-shaped mounting groove 301 is carved into the side wall of the support plate 101 near the chain 108 and is located at the end of the conveyor groove 102 away from the drive wheel 105. The T-shaped component 302 is installed in the T-shaped mounting groove 301, and a V-shaped cutting head 303 is provided at its end near the drive wheel 105. The pair of conveyor wheels 304 are respectively fixed to a pair of driven shafts 106 located at the front end of the support plate 101. After the packaging bag is sealed by the two pairs of sealing wheels 203 and moves to the pair of conveyor wheels 304, it is clamped onto the packaging bag by the pair of conveyor wheels 304 and the pair of chains 108, and the packaging bag is passed through the V-shaped cutting head 303, so that the V-shaped cutting head 303 cuts the packaging bag and cuts off the excess part at the end of the packaging bag. The T-shaped mounting groove 301 is used for the embedded mounting of the T-shaped part 302.

[0043] like Figures 1 to 5As shown, the receiving mechanism 4 includes a material box 401 and a waste box 402. The material box 401 is fixed to the front side of the support plate 101 away from the drive wheel 105, and a second sliding plate 404 is fixed thereon. The waste box 402 is fixed to the rear side of the support plate 101 away from the drive wheel 105, and a first sliding plate 403 is fixed thereon. The material box 401 is used to store sealed packaging bags, and the waste box 402 is used to store cut plastic scraps. After the packaging bag slides along the conveyor trough 102 to the end of the conveyor trough 102 away from the drive wheel 105, the cut packaging bag slides down the second sliding plate 404 into the material box 401, and the corner scraps slide down the first sliding plate 403 into the waste box 402.

[0044] Working principle: In operation, the transmission assembly first drives a pair of drive shafts 104 to rotate in opposite directions simultaneously. The drive shafts 104 drive a pair of drive wheels 105 to rotate synchronously, which in turn drive a pair of chains 108 to rotate in opposite directions. As the chains 108 rotate, the end of the packaging bag slides along the guide plate 103 into the conveying trough 102, pushing the bag between the chains 108. The end of the bag is clamped by the clamping blocks 110 on the chains 108, causing the chains to slide the bag from one end of the conveying trough 102 to the other. When the chains 108 move the bag to the two pairs of sealing wheels 203, the two pairs of sealing wheels provide a double seal.

[0045] When a pair of chains 108 move the packaging bag to a pair of conveyor wheels 304, the conveyor wheels 304 and chains 108 simultaneously clamp the packaging bag, and the packaging bag passes through the V-shaped cutting head 303, which cuts the packaging bag, removing the excess portion at the ends. The cut packaging bag slides down the second sliding plate 404 into the material box 401, while the scraps slide down the first sliding plate 403 into the waste box 402.

[0046] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this disclosure.
