Abstract
Description
Technical Field
[0001] This utility model relates to the field of bottom filling packaging machine technology, and in particular to an anti-pinch bag clamp for bottom filling packaging machines. Background Technology
[0002] Currently, on bottom-fill packaging machines, the packaging of materials is often done manually by loading the bags. The tool used manually is a bag clamp (the bag is manually placed onto the clamp, which then moves up and down along the vertical feed cylinder with the bag to complete the bottom filling). The main disadvantages of existing bag clamps are:
[0003] 1) Cannot clamp tightly: It can only clamp a small part of the bag and is easy to slip off.
[0004] 2) The bag is easily torn: It can only clamp a small part of the bag, and in order to prevent it from slipping, the cylinder is enlarged, which sometimes results in the bag being torn.
[0005] 3) Safety hazards: Workers may easily get their fingers pinched if they are not careful or do not follow the proper procedures when putting on the bags. Utility Model Content
[0006] The purpose of this utility model is to provide a solution to the above-mentioned technical problems.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A bag clamping device for bottom-fill packaging machines includes a bag clamping body, a bag clamping mechanism, and a sensing device. The bag clamping body consists of a mounting base, a cylinder, and anti-slip ribs. The mounting base is welded to the upper side of the cylinder, and the anti-slip ribs are welded to the lower side of the cylinder. The bag clamping mechanism consists of a bag clamping arm, a fixing rod, a bag clamping cylinder, a bag clamping rubber block, and a flexible clamping band. Two opposite bag clamping arms along the bag clamping body are connected as a whole by the fixing rod. The flexible clamping band is pressed and fixed to the two opposite bag clamping arms by the bag clamping rubber block. The telescopic rod of the bag clamping cylinder is connected to the fixing rod. The telescopic movement of the bag clamping cylinder realizes clamping and opening. The mounting bracket of the sensing device is bolted to the bag clamping body. The sensing plate is hinged to the mounting bracket by a pin. An inductive proximity switch is mounted on the end of the mounting bracket away from the sensing device.
[0009] Preferably, the anti-slip ribs are made of round steel or flat steel.
[0010] Preferably, the sensor is touched by a human hand by gravity, and the angle is swung by the lower limit and the upper limit.
[0011] Compared with the prior art, this utility model has the following advantages: This utility model uses ribs on the sleeve to increase resistance, male and female rubber bag clamping blocks on both sides, and flexible straps tightly attached to the sleeve to ensure that the bag is fully surrounded and clamped on the cylinder, so that it will not loosen or be torn; by setting touch switches on both sides (the touch switches automatically disconnect by gravity and are connected by human touch, and the sensing plate will not contact the inductive proximity switch, thus extending the service life of the inductive proximity switch), when manually bagging, only when the operation is standardized and the touch switches on both sides receive the signal at the same time will the bag clamping action be allowed, thereby fundamentally eliminating the hidden danger of pinching fingers.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0017] like Figure 1-3 As shown, an anti-pinch bag clamp for a bottom-fill packaging machine includes a bag clamp body 1, a bag clamping mechanism 2, and a sensing device 3. The bag clamp body 1 consists of a mounting base 11, a cylinder 12, and anti-slip ribs 13. The mounting base 11 is welded to the upper side of the cylinder 12; the anti-slip ribs 13 are welded to the lower side of the cylinder 12. The bag clamping mechanism 2 consists of bag clamping arms 21, a fixing rod 22, a bag clamping cylinder 23, a bag clamping rubber block 24, and a flexible clamping band 25. The two bag clamping arms 21, which are opposite each other along the bag clamp body 1, are connected by the fixing rod 22. The flexible clamping band 25 is pressed and fixed to the two opposing clamping arms 21 by the clamping rubber block 24. The telescopic rod of the clamping cylinder 23 is connected to the fixed rod 22. The telescopic movement of the clamping cylinder 23 realizes clamping and opening. The mounting bracket 31 of the sensing device 3 is bolted to the main body 1 of the bag clamper (which can be adjusted up and down). The sensing plate 32 is hinged to the mounting bracket 31 by the pin 34. The inductive proximity switch 33 is mounted on the end of the mounting bracket 31 away from the sensing device 3.
[0018] The anti-slip ribs 13 are made of round steel or flat steel, etc. The sensing device can be installed on the bag clamp body 1 or in other parts. The sensing plate 32 is touched by gravity and swings at a certain angle through the lower limit 311 and the upper limit 312. By setting touch switches on both sides, the touch switches will automatically disconnect by gravity and the signal will be connected by human touch. The sensing plate will not contact the inductive proximity switch, thus extending the service life of the inductive proximity switch. When manually bagging, the bag clamping action is only allowed when the operation is standardized and both touch switches receive signals at the same time, thereby fundamentally eliminating the risk of pinching fingers.
[0019] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
