Description

Technical Field

[0001] This utility model relates to the field of agricultural production technology, and more specifically, to a handheld bagging mechanism. Background Technology

[0002] In many sectors, including agriculture, food processing, and small-scale manufacturing, bagging is a common and crucial operational procedure. To keep the surface of items clean and sealed, they are usually placed in bags for simple sealing, which facilitates subsequent storage and transportation.

[0003] However, existing bagging methods have the following problems:

[0004] When bagging items, the traditional manual bagging method is still used. The traditional bagging method mostly relies on pure manual operation. The operator needs to open the bag with one hand and put the item in with the other hand, and then seal it. This process is not only inefficient, but also consumes a lot of manpower, which is not conducive to reducing costs and improving efficiency, and it is difficult to ensure the consistency and airtightness of the seal.

[0005] This invention features a main rod, sleeve, and other components that work together to facilitate operation, significantly improve bagging speed, and ensure a tight bag opening by coordinating the pressing frame and receiving groove. The reset spring automatically and quickly pulls the left and right clamps back to their initial open positions, eliminating the need for operators to spend extra effort on adjustments and greatly shortening the bagging interval. Utility Model Content

[0006] The present invention aims to solve the technical problems mentioned in the background art and provide a handheld bagging mechanism.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a handheld bag-making mechanism, comprising: a clamping plate, a main rod disposed below the clamping plate, and fixed plates connected to the left and right ends of the clamping plate by hinges. The clamping plate is composed of a right clamping plate and a left clamping plate. The fixed plates are respectively installed at the right end of the right clamping plate and the left end of the left clamping plate. Hinges two are fixedly installed on the inner side of each fixed plate. The fixed plates are connected to the clamping plate hinges via hinges two. A pressing frame is fixedly installed at the upper end of the clamping plate, and hinges one are fixedly installed at the middle of the front and rear sides of the upper end of the pressing frame.

[0008] A further preferred embodiment: The hinge has receiving grooves on both the left and right sides, and the internal size of the receiving grooves is larger than that of the hinge.

[0009] A further preferred embodiment: both the bottom inner sides of the left and right clamping plates are provided with moving grooves, and the front and rear sides of the moving grooves are provided with sliding grooves.

[0010] A further preferred embodiment: a sleeve is nested at the upper end of the main rod, a crossbar is fixedly installed at the upper end of the sleeve, connecting rods are fixedly installed at both ends of the crossbar, and sliding rods are fixedly installed at the upper ends of the connecting rods. The front and rear ends of the sliding rods are slidably connected to the sliding grooves opened inside the moving grooves opened on the inner sides of the left and right clamping plates.

[0011] A further preferred embodiment: a limit block is fixedly installed at the bottom of the main rod.

[0012] A further preferred embodiment: a return spring is fixedly installed on the inner side of the fixing plate, and the other end of the return spring is fixedly connected to the bottom of the right clamping plate and the left clamping plate respectively.

[0013] Beneficial effects:

[0014] 1. By incorporating a receiving groove, the pressing frame needs to fit tightly during the bag opening compression operation to achieve a good sealing effect. Without the receiving groove, the structural volume of the hinge itself may prevent the pressing frame from being completely folded and closed, resulting in some areas of the bag opening not being fully compressed, leaving gaps and affecting the bag's sealing performance. The space of the receiving groove is larger than that of the hinge, allowing the hinge to enter without obstruction during the folding process of the pressing frames approaching each other, ensuring that the pressing frame can achieve an ideal folded and fitted state, allowing the bag opening to be evenly and tightly closed. When the pressing frame can be perfectly closed, its entire working surface can effectively act on the bag opening, enhancing the degree of compression of the bag opening.

[0015] 2. By setting a limit block, during the frequent use of the bagging mechanism, the sleeve needs to slide up and down along the main rod to drive the opening and closing of the clamping plate and other actions. Without the limit block, when the sleeve slides down due to improper operation or other factors, it is very easy to swallow the main rod. The existence of the limit block can effectively prevent the sleeve from swallowing the entire main rod when it slides down, thereby ensuring that the main rod can always maintain the proper structural state and maintain the basic structural integrity of the entire handheld bagging mechanism.

[0016] 3. With the addition of a return spring, after the bagging operation is completed, the operator needs to return the clamps to their initial open position in order to perform the next bagging. Without the return spring, this process would have to be done manually, which is not only time-consuming and laborious, but also prone to causing abnormal clamp positions due to inaccurate operation, affecting the subsequent bagging efficiency. However, the return spring, with its own elastic restoring force, can automatically and quickly pull the left and right clamps back to their initial open positions when the sleeve is pulled up, without requiring the operator to spend extra effort to adjust. This greatly shortens the bagging interval time, allowing the entire bagging process to be carried out quickly and smoothly, significantly improving work efficiency.

[0017] 4. In summary, this handheld bagging mechanism, through the design of a pressing frame, receiving groove, sliding groove, sliding rod, and return spring, features a clamping plate consisting of left and right clamping plates. The pressing frame is fixed at the upper end and connected via a hinge with a receiving groove. The receiving groove provides flexible space for the hinge, ensuring the pressing frame can move freely during bagging and sealing operations, avoiding structural interference and ensuring a tight bag opening. The bottom inner side of the clamping plate has a sliding groove that slides in conjunction with the sliding rod connected to the sleeve on the main rod. The operator pushes the sleeve, causing the sliding rod to slide along the groove, which in turn drives the clamping plate to open and close around the hinge, achieving rapid opening and clamping of the bag opening and efficiently completing the bagging process. Furthermore, after bagging, the return spring automatically pulls the clamping plate back to its initial open state, facilitating the next bagging operation, buffering the impact of the clamping plate opening and closing, protecting the mechanism components, and optimizing the operating feel. The coordinated operation of all structures in the entire bagging mechanism greatly improves the convenience, accuracy, and efficiency of bagging operations. Attached Figure Description

[0023] The following will refer to the appendix in the embodiments of this utility model. Figures 1-4 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0024] Please see Figure 1-4In this embodiment of the utility model, a handheld bag-making mechanism includes: a clamping plate 1, a main rod 2 disposed below the clamping plate 1, and fixing plates 3 hinged to the left and right ends of the clamping plate 1. The clamping plate 1 is composed of a right clamping plate 101 and a left clamping plate 102. The fixing plates 3 are respectively installed at the right end of the right clamping plate 101 and the left end of the left clamping plate 102. Hinges 2 301 are fixedly installed on the inner side of the fixing plates 3. The fixing plates 3 are hinged to the clamping plate 1 through the hinges 2 301. A pressing frame 103 is fixedly installed on the upper end of the clamping plate 1. Hinges 1 104 are fixedly installed on the middle of the front and rear sides of the upper end of the pressing frame 103. The bottom of the inner side of the left clamping plate 102 and the right clamping plate 101 are both provided with a sliding opening. The moving groove 106 has sliding grooves 107 on both its front and rear sides. A sleeve 201 is nested at the upper end of the main rod 2. A crossbar 202 is fixedly installed at the upper end of the sleeve 201. Connecting rods 203 are fixedly installed at both ends of the crossbar 202. Sliding rods 204 are fixedly installed at the upper ends of the connecting rods 203. The front and rear ends of the sliding rods 204 are slidably connected to the sliding grooves 107 inside the moving grooves 106 on the inner sides of the left and right clamping plates 102 and 101. The left and right clamping plates 1 are in a naturally open state because the fixed plate 3 is connected to the clamping plates 1 by hinge 301, providing a certain degree of freedom of movement. The sleeve 201 on the main rod 2 is nested at the upper end of the main rod 2. The connecting rods 203 and sliding rods 204 at both ends of the crossbar 202 are located within the moving groove 106. At this time, the entire mechanism is in a ready-to-operate state, allowing the operator to hold the main rod 2 for the next action. The operator first opens the plastic bag, places the two sides of the bag opening on the outside of the pressing frame 103 on the left clamp 102 and right clamp 101 respectively, and applies glue or attaches adhesive strips to the bag opening. The item to be bagged (such as fruit, parts, etc.) is aligned with the opened bag opening and slowly placed into the bag so that the item touches the bottom of the bag. At this time, the pressing frame 103 is located below the item. Then, the operator holds the main rod 2 with both hands and pushes the sleeve 201 downward. The sleeve 201 drives the crossbar 202 to descend. The connecting rods 203 and sliding rods 204 at both ends of the crossbar 202 slide downward along the sliding groove 107 in the moving groove 106. Since the slide bar 204 and the clamping plate 1 are slidably connected, the descent of the slide bar 204 will cause the left clamping plate 102 and the right clamping plate 101 to rotate inward around the second hinge 301, and bring the left clamping plate 102 and the right clamping plate 101 closer to each other, so that the bag openings come into contact with each other, thereby gradually clamping the plastic bag opening. After the item is completely put into the bag, the operator slowly pulls the sleeve 201 upward, so that the slide bar 204 moves upward along the slide groove 107. Under the action of the second hinge 301, the left clamping plate 102 and the right clamping plate 101 gradually loosen their clamping on the bag opening. When the left clamping plate 102 and the right clamping plate 101 are flat, the main rod 2 can be moved downward directly to make the bag detach from the clamping plate 1, thus completing the bagging work.

[0025] In this embodiment of the invention, hinge 104 has receiving grooves 105 on both its left and right sides. The internal size of the receiving grooves 105 is larger than that of hinge 104. Because the space of the receiving grooves 105 is larger than that of hinge 104, hinge 104 can enter the receiving grooves 105 without obstruction during the process of the pressing frames 103 approaching and folding together. This avoids the awkward situation where the pressing frames 103 cannot be completely closed due to the space occupied by the structure of hinge 104 itself. For example, in scenarios where the bag opening needs to be tightly closed and compressed, if there is no suitable space, hinge 104 may "push" against it, making it difficult for the pressing frame 103 to achieve the ideal folded fit, thus affecting the effective compression of the bag opening. Because the pressing frame 103 can be folded and closed smoothly, when the bag opening is compressed, it can be closed more evenly and tightly, and its entire working surface can effectively act on the bag opening, thereby improving the degree of compression of the bag opening and enhancing the sealing performance of the bag.

[0026] In this embodiment of the invention, a limiting block 205 is fixedly installed at the bottom of the main rod 2. During operation, the sleeve 201 slides up and down along the main rod 2 to drive the movement of related components, thereby realizing the opening and closing of the clamp 1 and other functions. The presence of the limiting block 205 can effectively prevent the sleeve 201 from swallowing the entire main rod 2 when it slides down.

[0027] In this embodiment of the utility model, a return spring 302 is fixedly installed on the inner side of the fixing plate 3. The other end of the return spring 302 is fixedly connected to the bottom of the right clamping plate 101 and the left clamping plate 102 respectively. During the bagging operation, when the operator pushes the sleeve 201 downward, the slide rod 204 slides downward along the slide groove 107, causing the left clamping plate 102 and the right clamping plate 101 to rotate inward around the hinge 301 to clamp the bag and open the bag opening, the return spring 302 begins to play its role when the bagging is completed and the sleeve 201 is pulled upward. Relying on its own elastic restoring force, the reset spring 302 can automatically pull the left clamp 102 and the right clamp 101 back to their initial open state, eliminating the need for operators to manually adjust the position of the clamps and preparing for the next bagging operation. This greatly improves the convenience and efficiency of the operation, allowing the entire bagging process to be repeated quickly and smoothly. During the reset process, it is necessary to control the reset speed. If the speed is too fast, the bottom of the clamp 1 may hit the item in the bag. When the reset is about to be completed, hold the sleeve 201 to stop the reset, and then move the entire device downwards away from the bagged item before completing the reset action.

[0028] Working Principle: First, ensure the left clamping plate 102 and right clamping plate 101 are in a naturally open state. The sleeve 201 on the main rod 2 is nested at the upper end of the main rod 2. The connecting rods 203 and sliding rods 204 at both ends of the crossbar 202 are located within the moving groove 106. The operator holds the main rod 2, and the entire mechanism is ready for bagging. Take a plastic bag, open the bag opening, and place the two sides of the bag opening on the outside of the pressing frames 103 on the left clamping plate 102 and right clamping plate 101 respectively. Apply glue or attach adhesive strips to the bag opening according to the packaging requirements. Move the entire device towards the item, aligning the item with the open bag opening until the item touches the bottom of the bag. At this point, the pressing frame 103 is located below the item. Hold the main rod 2 with both hands and push the sleeve 201 downwards. The sleeve 201 causes the crossbar 202 to descend, and the connecting rods 203 and sliding rods 204 at both ends of the crossbar 202 slide downwards along the sliding grooves 107 within the moving groove 106. Since the slide bar 204 and the clamping plate 1 are slidably connected, the descent of the slide bar 204 will cause the left clamping plate 102 and the right clamping plate 101 to rotate inward around the second hinge 301, bringing the left clamping plate 102 and the right clamping plate 101 closer together, thereby gradually clamping the opening of the plastic bag and ensuring that the bag fits the item tightly. After the item is completely placed in the bag, the operator slowly pulls the sleeve 201 upward, causing the slide bar 204 to move upward along the slide groove 107. Under the action of the second hinge 301, the left clamping plate 102 and the right clamping plate 101 gradually loosen their clamping on the bag opening. During this process, since the inner side of the fixing plate 3 is fixedly installed with a return spring 302, and its other end is fixedly connected to the bottom of the right clamping plate 101 and the left clamping plate 102 respectively, the return spring 302 will automatically pull the left clamping plate 102 and the right clamping plate 101 back to the initial open state. However, care should be taken to control the return speed, because if the speed is too fast, the bottom of the clamping plate 1 may hit the item in the bag. Just before the reset is complete, hold the sleeve 201 to stop the reset, then move the entire device downwards away from the bagged item before completing the reset action, thus completing one full bagging operation. Throughout the operation, the limiting block 205 at the bottom of the main rod 2 effectively prevents the sleeve 201 from sliding downwards and engulfing the entire main rod 2, ensuring the normal operation of the mechanism; while the receiving grooves 105 on both sides of the hinge 104 ensure that the pressing frame 103 can be smoothly folded and closed when pressing the bag opening, improving the tightness and sealing of the bag opening and optimizing the bagging effect.
