Description

Technical Field

[0001] The utility model belongs to the technical field of clamping devices, and particularly relates to a clamping mechanism for bagging. Background Technique

[0002] The sub-packaging of traditional Chinese medicine requires the dispersion, mixing, impurity removal, bagging, weighing and sewing of the piled traditional Chinese medicine. Currently, the bagging work is generally that workers put a cloth bag on the discharge port of the hopper and continuously hold it by hand until all the medicinal materials are put into the cloth bag. In this bagging method, workers holding the cloth bag by hand for a long time are likely to cause fatigue in the hands of workers, which in turn increases the labor intensity of workers, and the work efficiency is also relatively low.

[0003] In view of this, in order to solve the problems of high labor intensity of workers and low work efficiency, the utility model proposes a clamping mechanism that can clamp the cloth bag at the discharge port to liberate the hands of workers, reduce the labor intensity of workers and improve work efficiency. The structure of the mechanism is simple and the cost is low. Summary of the Invention

[0004] The utility model provides a clamping mechanism for bagging, which has a simple structure and low cost. When bagging, the cloth bag can be clamped at the discharge port, reducing the labor intensity of workers and improving work efficiency. The specific scheme is as follows:

[0005] A clamping mechanism for bagging includes an operating table and a conveyor arranged on the operating table. A loading hopper is arranged on the lower side of the output end of the conveyor. A double-headed cylinder is respectively arranged on one opposite side of the discharge port of the loading hopper, and clamping blocks are respectively arranged on the other opposite side. The two clamping blocks are attached to the side wall of the discharge port of the loading hopper. The double-headed cylinder is connected to a controller. The two ends of the two clamping blocks are respectively connected to the output ends of the double-headed cylinders on the opposite sides. Clamping sub-blocks are horizontally arranged on both side walls of the loading hopper corresponding to the two clamping blocks. A plurality of limiting holes are spaced apart along the length direction of the two clamping sub-blocks. Limiting protrusions corresponding to the plurality of limiting holes are arranged on the corresponding clamping blocks. Installation blocks are arranged on both sides at the lower end of the loading hopper. The double-headed cylinder is detachably arranged on the installation blocks. Tightening blocks that can extend along the bottom surface of the installation blocks are horizontally arranged on the two clamping blocks opposite to the two ends of the installation blocks.

[0006] Furthermore, the depths of the plurality of limiting holes are the same as the lengths of the plurality of limiting protrusions.

[0007] Still further, anti-slip rubber pads are arranged on the inner walls of the plurality of limiting holes, the ends of the plurality of limiting protrusions and the free ends of the two tightening blocks.

[0008] The beneficial effects of the utility model are:

[0009] A clamping mechanism for bagging of the present utility model includes two double-headed cylinders arranged on both sides of the discharge port of a loading funnel and two clamping blocks connected to the output ends of the two double-headed cylinders. When bagging, workers only need to put a cloth bag on the side wall of the discharge port and control the operation of the two double-headed cylinders. Their output ends can drive the two clamping blocks to move relatively, and then the cloth bag can be clamped on the side wall of the discharge port. By setting a pressing block, an arc-shaped clamping groove and an arc-shaped clamping block, the cloth bag can be further clamped on the side wall of the discharge port, liberating the hands of workers during bagging, reducing the labor intensity of workers and further improving work efficiency.

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0016] Refer to Figures 1-4, A clamping mechanism for bagging, including an operation table and a conveyor arranged on the operation table. There is a loading funnel 1 under the output end of the conveyor. On one opposite side of the discharge port of the loading funnel 1, double-headed cylinders 2 are respectively arranged, and on the other opposite side, clamping blocks 3 are respectively arranged. The discharge port of the loading funnel 1 is of a rectangular structure. Among them, the two double-headed cylinders 2 are respectively located on both sides in the width direction, and the two clamping blocks 3 are respectively located on both sides in the length direction. The double-headed cylinders 2 are connected to the controller. The two clamping blocks 3 are in contact with the side wall of the discharge port of the loading funnel 1. Both ends of the two clamping blocks 3 are respectively connected to the output ends of the double-headed cylinders 2 on the opposite side. When bagging, the cloth bag is sleeved on the discharge port. The controller controls the two double-headed cylinders 2 to work, and their output ends drive the two clamping blocks 3 to approach the discharge port. When the cloth bag is pressed against the side wall of the discharge port, the clamping of the cloth bag can be completed; on both side walls of the loading funnel 1 corresponding to the two clamping blocks 3, clamping auxiliary blocks 4 are horizontally arranged. Along their length directions, a number of limiting holes 5 are spaced apart on the two clamping auxiliary blocks 4. On the corresponding clamping blocks 3, there are limiting protrusions 6 corresponding to the number of limiting holes 5 one by one. The setting of the number of limiting holes 5 and the number of limiting protrusions 6 is convenient for increasing the contact area when clamping the cloth bag and better clamping and fastening the cloth bag; on both sides at the lower end of the loading funnel 1, mounting blocks 7 are arranged. The double-headed cylinders 2 are detachably arranged on the mounting blocks 7. On both clamping blocks 3 opposite to both ends of the mounting blocks 7, pressing blocks 8 that can extend along the bottom surface of the mounting blocks 7 are horizontally arranged. The pressing blocks 8 at both ends can press against the cloth bag on the side away from the clamping blocks 3, so that the circumference of the cloth bag can be clamped.

[0017] The depth of the number of limiting holes 5 is the same as the length of the number of limiting protrusions 6, so that when clamping the cloth bag, the number of limiting holes 5 and the number of limiting protrusions 6 are more closely fitted.

[0018] Anti-slip rubber pads are arranged on the inner walls of the number of limiting holes 5, the ends of the number of limiting protrusions 6, and the free ends of the two pressing blocks 8, which can enhance the friction force when clamping the cloth bag and prevent the cloth bag from falling due to excessive weight during bagging.

[0019] Working principle: When bagging, first sleeve the cloth bag on the end of the discharge port of the loading funnel 1. The controller controls the two double-headed cylinders 2 to work, and their output ends drive the two clamping blocks 3 to approach the side wall of the discharge port. When the number of limiting protrusions 6 drives the cloth bag to fit with the limiting holes 5 and the pressing blocks 8 on the two clamping blocks 3 drive the cloth bag to be pressed tightly, the clamping of the cloth bag can be completed. After the bagging is completed, the worker holds the cloth bag. At this time, the two double-headed cylinders 2 are controlled to start, driving the two clamping blocks 3 on them to gradually move away from the discharge port of the loading funnel 1, and the cloth bag can be taken off.
