Description

Technical Field

[0001] This utility model relates to the field of agricultural product packaging technology, specifically a clamping and heating mechanism. Background Technology

[0002] Agricultural products refer to primary products derived from planting, forestry, animal husbandry, and fisheries, namely plants, animals, microorganisms and their products obtained in agricultural activities, such as rice, sorghum, peanuts, corn, wheat, dried matsutake mushroom slices, and local specialties of various regions. Agricultural products need to be sealed using vacuum packing machines during the packaging process. Vacuum packing machines are equipped with clamping and heating mechanisms inside.

[0003] Existing clamping and heating mechanisms typically consist of two sets of identical frames and heating components. By closing the packing machine cover, the upper and lower frames can fit together, thereby pressing and clamping the outlet end of the packaging bag. During the clamping process, the heating components heat the clamping area to complete the sealing operation of the packaging bag. After the sealing is completed, the excess portion of the packaging bag needs to be manually torn off. Manual tearing can result in an uneven outlet of the packaging bag, which in turn affects the overall sealing of the packaging bag. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping heating mechanism to solve the problem mentioned in the background art that after the clamping heating mechanism is sealed, it is necessary to manually tear off the excess part of the packaging bag, which will result in uneven packaging bag outlet.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping and heating mechanism, comprising a storage part and a clamping part. The storage part has a storage frame bolted to the top of a packaging machine, and a support frame is fixed inside the storage frame. The clamping part is located above the storage frame and has a flip-top plate connected to the top of the storage frame via a rotating connector. A heating clamping frame is fixed to the bottom inner side of the flip-top plate. An installation frame is fixed to the outer wall of the heating clamping frame. An electric telescopic rod is fixed to the outer wall of the installation frame. An output rod is fixedly connected to the output end of the electric telescopic rod. A transmission block is fixedly sleeved on the output rod. A first connecting rod is hinged to the bottom of the transmission block, and an installation block is hinged to the bottom end of the first connecting rod. A cutting blade is fixed to the bottom of the installation block. Driving the electric telescopic rod pushes the output rod to move longitudinally relative to the storage part, thereby moving the transmission block.

[0006] By adopting the above technical solution, the output rod can be driven to move by activating the electric telescopic rod. The movement of the output rod can drive the cutting blade to move vertically under the influence of the first connecting rod. The vertical movement of the cutting blade can cut off the excess parts of the packaging bag, reduce the occurrence of unevenness at the packaging bag outlet, and ensure the subsequent sealing effect of the packaging bag.

[0007] Preferably, the clamping part further has a second connecting rod hinged to the other side of the mounting block that is in contact with the heating clamping frame, and a transmission frame is hinged to the bottom end of the second connecting rod, and a stretching roller is rotatably connected to the bottom of the transmission frame.

[0008] By adopting the above technical solution, during the downward movement of the mounting block, the transmission frame will be driven to move under the action of the second connecting rod. The movement of the transmission frame will drive the stretching roller to move. The movement of the stretching roller will flatten the excess part of the packaging bag before it is cut, thereby ensuring the flatness of the cut part of the packaging bag.

[0009] Preferably, a sliding rod is fixedly provided on the inner wall of the mounting frame, and the sliding rod is slidably connected to the output rod.

[0010] By adopting the above technical solution, the sliding rod can limit one end of the output rod, thus improving the stability of the output rod during its movement.

[0011] Preferably, a limiting plate is fixedly provided on the upper inner side of the mounting frame, and the limiting plate is in contact with the transmission block.

[0012] By adopting the above technical solution, the transmission block can be limited by the limiting plate, thus ensuring the stability of the transmission block during its movement.

[0013] Preferably, there are three sets of transmission blocks, and the bottom of each of the three sets of transmission blocks is hinged to a first connecting rod.

[0014] By adopting the above technical solution, the installation block can be better pushed downward by setting three sets of transmission blocks, thus ensuring the stability of the installation block during vertical movement.

[0015] Preferably, the transmission frame is provided with limit protrusions on both sides, and the limit protrusions are slidably connected to the mounting frame.

[0016] By adopting the above technical solution, the movement trajectory of the transmission frame can be limited to a certain extent by the limiting protrusion, so that the stretching roller can better push the packaging bag to flatten.

[0017] Preferably, the inside of the stretching roller is made of stainless steel, and a rubber pad is provided on the outside of the stretching roller.

[0018] By adopting the above technical solution, the rubber pads allow the stretching roller to better push the packaging bag to move and make it flat.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] (1) By starting the electric telescopic rod, the output rod can be driven to move. The movement of the output rod can drive the cutting blade to move vertically under the influence of the first connecting rod. The vertical movement of the cutting blade can cut off the excess parts of the packaging bag, reduce the occurrence of unevenness at the outlet of the packaging bag, and ensure the subsequent sealing effect of the packaging bag.

[0021] (2) During the downward movement of the mounting block, the transmission frame will be driven to move under the action of the second connecting rod. The movement of the transmission frame will drive the stretching roller to move. The movement of the stretching roller will flatten the excess part of the packaging bag before it is cut, thereby ensuring the flatness of the cut part of the packaging bag.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] The following is in conjunction with the appendix Figure 1-6 The present invention will be described in further detail below.

[0032] Example 1

[0033] Please see Figure 1-6 This embodiment provides a technical solution: a clamping and heating mechanism, including a storage part 1 and a clamping part 2. The storage part 1 has a storage frame 101 bolted to the top of a packaging machine. A support frame 102 is fixed inside the storage frame 101 and connected to the storage frame 101 by bolts, facilitating disassembly or installation by the operator. The clamping part 2 is located above the storage frame 101 and has a flip-top plate 201 connected to the top of the storage frame 101 by a rotating connector. A heating clamping frame 202 is fixed to the bottom inner side of the flip-top plate 201. The heating clamping frame 202 mainly consists of a heating plate and a clamping frame. By activating the heating plate, the packaging bag at the bottom of the clamping plate can be sealed. An installation frame 203 is fixed to the outer wall of the heating clamping frame 202 and bolted to prevent the heating clamping frame 202 from separating from the installation frame 203.

[0034] An electric telescopic rod 204 is detachably mounted on the outer wall of the mounting frame 203. The electric telescopic rod 204 is electrically connected to the control board of the packaging machine, and the mounting frame 203 can be controlled by the controller of the packaging machine. An output rod 205 is fixedly connected to the output end of the electric telescopic rod 204. The operation of the electric telescopic rod 204 can drive the output rod 205 to move. A transmission block 206 is fixedly sleeved on the output rod 205. The movement of the output rod 205 can drive the transmission block 206 to move in the same way. A first connecting rod 207 is hinged to the bottom of the transmission block 206. The horizontal movement of the transmission block 206 can drive the first connecting rod 207 to rotate. An installation block 208 is hinged to the bottom of the first connecting rod 207. The rotation of the first connecting rod 207 can drive the installation block 208 to move vertically. A cutting blade 209 is fixedly provided at the bottom of the installation block 208. Driving the electric telescopic rod 204 pushes the output rod 205 to move longitudinally relative to the storage part 1, thereby driving the transmission block 206 to move.

[0035] The vertical movement of the mounting block 208 will drive the cutting blade 209 to move downwards. A sliding rod 213 is fixedly provided on the inner wall of the mounting frame 203, and the sliding rod 213 is slidably connected to the output rod 205. The sliding rod 213 can limit one end of the output rod 205 to ensure the stability of the output rod 205 during movement. A limiting plate 214 is fixedly provided on the upper inner side of the mounting frame 203, and the limiting plate 214 is in contact with the transmission block 206. The limiting plate 214 can limit the transmission block 206 to ensure the stability of the transmission block 206 during movement. There are three sets of transmission blocks 206, and the bottom of each of the three sets of transmission blocks 206 is hinged to a first connecting rod 207. By setting three sets of transmission blocks 206, the mounting block 208 can be pushed downwards more effectively, ensuring the stability of the mounting block 208 during vertical movement.

[0036] Example 2

[0037] Please see Figure 1-6 The clamping part 2 also has a second connecting rod 210 hinged to the other side of the mounting block 208 that is in contact with the heating clamping frame 202. When the mounting block 208 moves horizontally, it can drive the second connecting rod 210 to rotate. The bottom end of the second connecting rod 210 is hinged to a transmission frame 211. The rotation of the second connecting rod 210 will drive the transmission frame 211 to move. The bottom of the transmission frame 211 is rotatably connected to a stretching roller 212. The movement of the transmission frame 211 will drive the stretching roller 212 to move. The movement of the stretching roller 212 pushes... The transmission frame 211 moves to cut the outer packaging bag. Both sides of the transmission frame 211 are provided with limiting protrusions, and the limiting protrusions are slidably connected to the mounting frame 203. The limiting protrusions can limit the movement trajectory of the transmission frame 211 to a certain extent, so that the stretching roller 212 can better push the packaging bag to flatten it. The inside of the stretching roller 212 is made of stainless steel, and the outside of the stretching roller 212 is provided with a rubber pad. The rubber pad allows the stretching roller 212 to better push the packaging bag to move and flatten it.

[0038] Working principle: First, when the packaging bag needs to be clamped, place the packaging bag with the agricultural product end inside the support frame 102. Then, select the required position of the packaging bag and close the flip cover 201. The rotation of the flip cover 201 will drive the heated clamping frame 202 to move and fit against the support frame 102, thereby clamping the sealing position of the packaging bag. Then, start the vacuum packing machine to draw a vacuum. After vacuuming, start the heating module inside the heated clamping frame 202 to heat and seal the packaging bag. After the packaging bag is sealed, start the electric telescopic rod 204. The operation of the electric telescopic rod 204 will drive the output rod 205 to move. The movement of the output rod 205 will drive the transmission block 206 to move. Since the transmission block 206 is hinged to the first connecting rod 207, and the first connecting rod 207 is hinged to the mounting block 208, and the mounting block 208 is slidably connected to the inner wall of the mounting frame 203, the movement of the transmission block 206 will drive the mounting block 208 to move downward under the action of the first connecting rod 207.

[0039] Secondly, since the mounting block 208 is hinged to the second connecting rod 210, and the second connecting rod 210 is hinged to the transmission frame 211, and the limiting protrusion of the transmission frame 211 is slidably connected to the inner wall of the mounting frame 203, the movement of the mounting block 208 will drive the transmission frame 211 to move horizontally under the action of the second connecting rod 210. The movement of the transmission frame 211 will drive the stretching roller 212 to move. Since the height of the stretching roller 212 is lower than that of the cutting blade 209, the stretching roller 212 will first fit with the excess part of the packaging bag, and the movement of the stretching roller 212 will push the packaging bag into a relatively tight state. Then, during the downward movement of the mounting block 208, it will drive the cutting blade 209 to move downward to cut off the excess part of the packaging bag, thereby reducing the occurrence of uneven sealing of the packaging bag.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
