Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic bag production technology, and in particular to a clamping and transverse movement mechanism. Background Technology
[0002] During the production process, plastic bags need to be laid out individually on a transfer rack, and then the stacks of plastic bags are clamped by a clamp to the subsequent folding station. However, due to the different sizes and specifications of the plastic bags produced, when the size is changed, the plastic bags laid out on the transfer rack and the subsequent folding station cannot be guaranteed to be aligned. This means that the subsequent production line needs to be laterally offset as a whole during the design and use, so as to generate a certain margin. Utility Model Content
[0003] The technical problem to be solved by this utility model is to address the aforementioned technical deficiencies by providing a clamping and lateral movement mechanism. This mechanism employs a clamp that slides laterally on a movable frame, working in conjunction with a drive mechanism. This allows the clamp to freely adjust the lateral position of the plastic bag after it has been clamped and removed from the transfer frame, before dragging it to the subsequent workstation. This addresses the misalignment between the plastic bag position on the front transfer frame and the plastic bag position at the subsequent folding workstation. Furthermore, since the clamp removes the plastic bag from the gap in the transfer frame, the clamp cannot move laterally at the bag removal position, which would cause it to collide with the transfer frame. Therefore, for those skilled in the art, installing a laterally movable clamp on the movable frame is not an easy concept to conceive.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a clamping and lateral movement mechanism, including a frame and a transfer frame disposed on the frame; a movable frame is mounted on the frame; the clamping and lateral movement mechanism is mounted on the movable frame; gaps are provided at intervals on the transfer frame, the gaps are opened in the swing direction, and the clamping and lateral movement mechanism is provided with clamps corresponding to the openings of the gaps; multiple clamps are laterally slidably mounted on the movable frame, and the movable frame is also provided with a drive mechanism for driving the clamps to slide laterally.
[0005] To further optimize this technical solution, the driving mechanism consists of a transverse belt mounted on a movable frame and a motor that drives the belt to rotate; multiple clamps are mounted and fixed on the belt.
[0006] To further optimize this technical solution, the clamp is positioned opposite to the gap, facing the direction of the transfer frame.
[0007] To further optimize this technical solution, a slide rail is installed on the movable frame, and the slide rail is arranged laterally along the movable frame.
[0008] To further optimize this technical solution, a slider is installed on the gripper; the gripper is slidably mounted on the slide rail via the slider.
[0009] To further optimize this technical solution, a bracket is installed between the multiple grippers; a slider is installed on the bracket; and the grippers are mounted on a slide rail via the bracket and the slider.
[0010] Compared with the prior art, this utility model has the following advantages: It employs a gripper that slides laterally on the moving frame, working in conjunction with a drive mechanism. This allows the gripper to freely adjust the lateral position of the plastic bag after it has been gripped and removed from the transfer frame, before dragging it to the subsequent workstation. This addresses the misalignment between the plastic bag position on the front transfer frame and the plastic bag position at the subsequent folding workstation. Furthermore, since the gripper removes the plastic bag from the gap in the transfer frame, it cannot move laterally at the bag removal position, as this would cause a collision with the transfer frame. Therefore, for those skilled in the art, installing a laterally movable gripper on the moving frame is not an easy concept to conceive. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0017] Detailed implementation method: combined with Figure 1-4As shown, the clamping and lateral movement mechanism includes a frame 1 and a transfer frame 2 mounted on the frame 1; the transfer frame 2 has a swingable type and a normally horizontal type, and a movable frame 3 is mounted on the frame 1; the clamping and lateral movement mechanism is mounted on the movable frame 3; gaps 4 are provided at intervals on the transfer frame 2, and the gaps 4 are opened in the swing direction; the clamping and lateral movement mechanism is provided with clamps 5 corresponding to the openings of the gaps 4; multiple clamps 5 are slidably mounted laterally on the movable frame 3, and the movable frame 3 is also provided with a drive mechanism for driving the clamps 5 to slide laterally.
[0018] The movable frame 3 is mounted on the frame 1 via sliding mechanisms on both sides. At the same time, the movable frame 3 is equipped with a corresponding reciprocating motion mechanism to realize the transfer of plastic bags between different workstations. This is common knowledge in the field. For example, a motor can be used to drive the belt to rotate in order to drive the movable frame 3 to transfer plastic bags between different workstations on the frame 1.
[0019] The driving mechanism consists of a transverse belt 7 mounted on the movable frame 3 and a motor 6 that drives the belt 7 to rotate; multiple clamps 5 are mounted and fixed on the belt 7.
[0020] The clamp 5 is oriented toward the transfer frame 2 and is positioned opposite the gap 4.
[0021] The movable frame 3 is equipped with a slide rail 8, which is arranged laterally along the movable frame 3.
[0022] The clamp 5 is equipped with a slider 9; the clamp 5 is slidably mounted on the slide rail 8 via the slider 9. Alternatively, a bracket 10 is installed between multiple clamps 5; the bracket 10 is equipped with sliders 9; the clamps 5 are mounted on the slide rail 8 via the bracket 10 and the sliders 9.
[0023] Combination Figure 1-4As shown, during use, the transfer frame 2 tilts downwards and swings to receive individual plastic bags to form a stack. Then it swings upwards to a position parallel to the gripper 5 on the moving frame 3. The moving frame 3 then moves, and the gripper 5 enters from the opening side of the gap 4, clamping the plastic bags from above and below the gap 4. At this time, due to the presence of the transfer frame 2, the gripper 5 cannot move laterally. When using a swingable transfer frame 2, after the transfer frame 2 swings downwards, or after the gripper 5 is pulled away from the transfer frame 2 by the moving frame 3, before reaching the next workstation, it can be driven by the motor 6. The belt 7 rotates, further driving the clamp 5 to move laterally on the moving frame 3. When a fixed horizontal transfer frame 2 is used, after the clamp 5 is pulled away from the transfer frame 2 by the moving frame 3, before reaching the next work station, the belt 7 can be driven to rotate by the motor 6, further driving the clamp 5 to move laterally on the moving frame 3. The plastic bag being pulled laterally may collide with other mechanisms, causing temporary creases and compression. However, when the moving frame 3 continues to drag the plastic bag to the next work station, the plastic bag will naturally stretch and flatten during the dragging process.
[0024] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.
[0025] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
